The full report is as follows：

“This is our new product.，Today, we will witness our innovative achievements with you.。”Take off slowly as the high-altitude tethered UAV，Jiangsu Xuzhou Hailunzhe Special Vehicle Co., Ltd.（Hereinafter referred to as Helen Zhe）Chen Huiyuan, director and deputy general manager, is confident in his voice.，“Now the UAV is at an altitude of 90 meters.……It's 150 meters now……”The dense snow-white fire fighting foam is transported from the fire truck to the UAV through the pipe belt.，Ejected at an altitude of more than 100 meters.。

“8 tons of water per truck，After the compressed air fire extinguishing foam is formed by automatic proportional mixing,‘Combat’Time can be extended from 2 minutes to half an hour。” High-altitude UAV fire extinguishing truck not only improves fire extinguishing efficiency, but also achieves high efficiency and water saving.。Fire-fighting combat vehicle with domestic leading level，It is just a microcosm of Helen Zhe's cultivation and development of new quality productivity.。

Diversified Development Helps Urban Flood Control

“Every drainage truck has to go through pressure.、Flow rate、Power and other tests，The sub-vehicle of the primary-secondary drainage vehicle often works underwater.，Therefore, the car has to be tested for 24 hours under two meters of water.。”Director of Helen Zhe R & D Center、Hu Demin, Minister of Emergency Department, introduced in detail the various tests that need to be carried out before each drainage truck leaves the factory.。

2020，In response to the state“Actively promote the modernization of emergency management system and capacity”A call，Helen Zhe is active in action，Scientific research，Finally, it focuses on the field of urban flood control in the emergency industry.。Helen Zhe, who started with R & D and production of special vehicles，Marching into the relatively unfamiliar field of urban flood control，How to get started？

Helen Zhe combines the original industrial advantages，Take the large capacity drainage special vehicle as the breakthrough point.，Explore the development of urban flood control and drainage。With the increasing pressure of urban flood control and drainage in recent years,，In 2023, Helen Zhe further optimized the organizational structure and set up a special emergency department.，Provide an integrated solution for drainage and rescue。Nowadays，Helen Zhe's emergency drainage vehicles have initially formed a series of products.，Including pump-set drainage truck、Primary and secondary drainage vehicles, drainage robots, etc.。2024，Helen Zhe Riding on the East Wind of New Quality Productivity，It will promote the development of high-end products such as boom drainage trucks.，Before the arrival of the flood season, 10 drainage emergency vehicles were built.，To contribute to winning the hard battle of flood control and disaster relief。

Not only in the development and production of drainage products“Work hard”，Helen Zhe also took practical actions to help flood control and disaster relief work throughout the country.。“In addition to dozens of Helen Zhe emergency power generation vehicles mobilized from all over the country to ensure power supply,，We also sent more than 10 employees carrying six sets of drainage equipment to the affected areas for support.。Pumping and drainage operations were carried out for eight consecutive days and nights.， Metro station 、Parking lots and other hard-hit areas have our figures.。”Recalling the torrential rain in Zhengzhou, Henan in 2021，Hu Demin said。

Technology Enabling Efficient Water Saving

“Considering that the performance test of each fire truck requires continuous operation at full flow for 6 hours，Consume hundreds or even thousands of cubic meters of water，All we use is continuously recycled water.。”Mention the water-saving effect of enterprises，Shanghai Graman International Fire Fighting Equipment Co., Ltd., a wholly-owned subsidiary of Helen Zhe（Hereinafter referred to as Graman）Deputy general manager Feng Hao said.。

In order to make the product meet the national standard，All kinds of fire engines in the company、Fire pumps and military vehicles shall be subject to hydraulic strength performance test of water pump、Sealing performance test of tank body、Rain test of the whole vehicle and the spray flow of the water cannon、Distance（ Spray ）And other performance tests，It needs to consume more water resources in the process of various tests.。“We always insist on saving resources.、The principle of recycling，All test facilities involving water，All of them are constructed according to the concept of recycling.。”Feng Hao introduced，Helen Zhe is in the car、The circulating reservoir is designed for the fire pump test bench.；On the deluge test stand and at the impact point of the water cannon，Set up a trench，Collect the water falling to the ground to the sedimentation tank。

“We have also integrated the concept of water saving into product development and design.，Committed to achieving efficient water conservation through technology。”Yang Weili, general manager of Graman, added.。The company's compressed air foam fire truck，Real-time monitoring of system flow and pressure parameters through intelligent control system，Can reasonably control that proportion of foam mix liquid and air，Compared to traditional system，Save water consumption 75％，At the same time, it can also significantly improve the fire extinguishing efficiency and reduce the use of stock solution.；Fire truck equipped with multi-agent combined fire extinguishing system，Mix thoroughly with dry powder and high pressure nitrogen，Maybe even“Extinguish fire without water”。

“Our liquid nitrogen fire truck is jointly developed with Sinopec Safety Engineering Research Institute.，Its application of liquid nitrogen and foam liquid mixed foaming fire extinguishing technology is in the leading position in the field of fire fighting in the world.。”Talking about the advantages of liquid nitrogen fire truck，Feng Hao talks a lot。Compared with ordinary foam fire truck，Extinguishing efficiency of liquid nitrogen foam fire truck increased by more than 2 times，Can save foam mix liquid（6％ Bubble ＋94％Water）40％Above。

“Helen Zhe will use more advanced technology.、More intelligent products help urban flood control，Improve water-saving efficiency。”Helen Zhe Chairman Gao Peng said.，“We will accelerate the development and manufacturing capabilities of intelligent equipment.，Sound the Development with New Quality Productive Forces‘Charge bugle’，High and new technology in the new era、High efficiency、Benchmarking enterprises in the industry on the road of high-quality development such as high efficiency。”
