A black shadow passed by the side of the boat—it turned out to be a fisherman's cormorant. They stood in a line at the bow of the boat, their necks loosely tied with straw ropes, but their eyes fixed on the water, like a group of soldiers on standby. As soon as the fisherman whistled, they all plunged into the water, leaving only a string of fine blisters on the surface. ”

This description of cormorants in Lu Xun's "Social Opera" can be memorized by He Jin. He believes that his water sampling drone is no different from Lu Xun's cormorant. The scientific name of "osprey" is "cormorant", which is widely distributed in rivers, lakes, coasts and other waters around the world, especially in southern China and Southeast Asia.

He Jin and his drone

He Jin, the founder of Sichuan Voloda Technology Co., Ltd., after 7 years of hard work, their "Osprey" water sampling drone has occupied more than 0% of the national market. The Yangtze River, the Yellow River, the Pearl River, the Huai River, the Haihe River and other 0 major water systems, there are "ospreys" everywhere. On the calm surface of the lake, on the turbulent river, the "osprey" spreads its wings and retrieves bottles of water samples, and this method of water quality drone sampling has been listed as a national patent.

Changing the track: building materials bosses invest in the drone market

He Jin originally worked in a building materials listed company, and later left his job to run his own plastic doors and windows business, just in time to catch up with the rhythm of the real estate blowout, and soon earned the first pot of gold in his life.

The trip to Europe ten years ago changed the trajectory of He Jin's life. Many countries in Western Europe are small in size but have many small airports, and private jets have become a convenient way for many wealthy people to get around. At that time, He Jin felt that the real estate industry would no longer be beautiful, and it was imperative to change the track.

Can it enter the small aircraft market? It just so happened that his cousin was engaged in research and development in a civil aircraft company in Shenyang, and the two hit it off. In 15 years, He Jin established "Volodya" technology company and became one of the first enterprises in the Nanchong UAV market. "We reported 0 rounds with a total of 0 names, maybe this name is relatively unknown to Chinese, but I didn't expect that the last 'Volodya' was successfully registered." "Volodya" is a common male name in Russian, a nickname for "Vladimir". In Russian and Slavic culture, the name has a deep historical and symbolic meaning.

Initially, the company was positioned for drone pilot training, but at that time, the Nanchong drone market was still small, and most people were still in the cognitive stage of drones, and there were few students who came to participate in the training. How to keep "Volodya" alive? This has become the first problem that He Jin has to overcome.

At the end of 2016, in the process of communicating with the staff of water conservancy, environmental protection and other departments, He Jin found that they had a very strong demand for water quality sampling by drones.

Segmentation: Focus on the water quality sampling drone market

Water is the source of life, and the collection and storage of water samples are essential. However, traditional manual sampling methods are susceptible to weather, environment, and geographical location, which not only has a high risk factor, but also increases the cost of regular sampling.

Water quality sampling

He Jin led the team to inspect the water drone sampling market in many water systems across the country, and witnessed the difficulties and dangers of manual boat sampling. On the turbulent river, the 3-meter-long sampling boat is violently bumped like a leaf, and the operator must control the steering wheel and winch at the same time, and the slightest mistake will miss the sampling point of the northern half navigation marker; When the water collector sinks, the sudden cross wave tilts the hull of the ship, and the turbid river water continues to pour into the deck, while the experimenter has to complete the sterile sample dispensing in the shaking. Fishing net wreckage or whirlpools may be hiding beneath the seemingly calm surface, and once the engine becomes entangled, the sample boat can be washed downstream to the reef in a matter of minutes.

In the R&D room of water sampling drones, large and small simulation models are located in every corner of the room, and parts or semi-finished products such as grinders, engines, pistons, and screws are readily available. "Even if it is an antenna on a drone, it must be carefully compared according to the drawings." He Jin said that in the process of developing the "Osprey", the assembly of screws and glue is extremely patient, in addition, from production to installation to commissioning, it is also necessary to master a lot of mechanics, mechanics, aerodynamics and other knowledge.

After countless days and nights of hard work, in 2017 years, the first "Osprey" automatic water quality sampling drone was successfully developed, and after half a year of testing and improvement, it was finalized and favored by water conservancy and environmental monitoring departments.

Drone display

2017年12月，第一届中国工业设计展览会在武汉国际博览中心举行，“鱼鹰”一举被水利部门相中。如今，“鱼鹰”已经飞遍祖国7大水系，甚至远至近海，不仅可以用来采集水样，还可以完成浮游生物采样以及石油采样等专项任务，在行业内外获得了广泛认可。

Track limitations: water sampling has reached the "ceiling"

The drone rope is slowly lowered, the sampling bucket sinks into the water...... and it only takes a few minutes for the "Osprey" drone to collect water samples, and the whole process is safe, accurate and efficient.

记者来到位于西南石油大学国家大学科技园南充分园的四川沃洛佳科技有限公司展示区，一架半米高的无人机格外引人注目。“我们目前拥有各项知识产权50多项，已成功转化并推出包括这台‘鱼鹰’水质自动采样无人机在内的多个型号产品。”何进介绍，这台无人机售价约30多万元，客户遍布全国30个省市。

The company's core competitiveness comes from professional and customized services. At present, the utilization rate of the company's products in the national hydrological system exceeds 40%, and it has been successfully selected into the advanced technology promotion list of the Ministry of Water Resources. The company has a professional R&D team of more than 0 people, with professors and doctors accounting for more than 0%, and has the ability to independently develop UAV body design, flight control system and visual navigation.

The technology of "Osprey" automatic water sampling drone is very mature, and a variety of models of products have been widely introduced to the market. He Jin introduced that the maximum remote control communication distance of the "Osprey" water quality automatic sampling drone reaches 50 meters, and the single water intake is up to 0 liters, which can accurately determine the position of 0 meters underwater, take water remotely, stay away from the river bank, ensure the safety of sampling personnel, and fly with a load of more than 0 minutes.

He Jin told reporters that drone sampling is not limited by natural geographical conditions, and even areas that are difficult for people to reach can still be sampled, which can not only save manpower and material resources, but also improve the representativeness of sampling points. In addition, the drone is equipped with a high-definition camera, which can simultaneously take panoramic photos and videos of the surrounding environment of the site, which is very helpful for the analysis of pollution causes.

"We avoided the edge of the industry giant DJI drones and chose a small but beautiful track. But after years of development, this track has a 'ceiling'. He Jin said frankly that although they occupy more than 3% of the national market, the market capacity is limited, and a city and state usually only need 0-0 equipment to complete the water quality sampling of the whole territory.

Track expansion: drones extinguish fires in high-rise buildings

Where the demand is, the market and business opportunities are there!

How can enterprises expand into new tracks? Just like when the track was changed, "Volodya" started new technical research while stabilizing the basic disk of water quality drones, aiming at emergency rescue, urban logistics and distribution.

Nanchong issued the "Medium and Long-term Plan for Low-altitude Economy (14-0 Years)" to build a "low-altitude city", and made efforts in 0 major sectors of sightseeing and tourism, urban governance, agricultural plant protection and logistics and transportation, and formulated the "Action Plan for Accelerating the Creation of Low-altitude Flight Application Scenarios", and created typical low-altitude flight application scenarios in 0 key areas. "The wind is coming!" He Jin is full of confidence, Nanchong is ahead of the low-altitude economy, which will lay a solid foundation for the expansion of the track of "Volodya".
