Recently, the Yunnan Mojiang Wenwu Tea Complementary Photovoltaic Power Generation-Ground Fire Box Pump Integrated Project undertaken by our company was successfully completed and delivered. This project is located in Longtan Township and Wenwu Town, Mojiang Hani Autonomous County, Pu'er City, Yunnan Province. As a key national new energy supporting project, its successful operation has built a fire safety barrier for this large-scale tea-solar complementary power station with an installed capacity of over one million kilowatts. It also marks a new level of our company's fire protection system integration service capabilities in the new energy field.

In view of the characteristics of the Chaguan complementary power station covering a large area, complex terrain, and scattered fire water sources, our technical team customized a Japanese-shaped integrated fire box pump integrated pump station plan with a bottom plate. The pumping station adopts a modular design with an overall size of 15×10×4m, supporting independent equipment room dimensions 15×5×4m, integrating fire protection water storage, pressurized water supply and intelligent control, realizing "one stop shop" Fire protection.

The main body of the pump station is welded with high-strength food-grade stainless steel and is equipped with complete safety auxiliary facilities, including anti-slip ladders, maintenance manholes, standardized various inlet and outlet openings, unpowered ventilators, fire-proof and anti-theft equipment room doors and anti-slip ladder steps, etc., to fully meet daily operation and maintenance and emergency maintenance needs.

The fire protection system configuration of this project has reached the industry-leading level and can simultaneously meet the fire extinguishing needs of different areas and different fire types in the power station:

Fire hydrant system: equipped with a set of high-performance fire hydrant skid-mounted pump unit, water inlet diameter DN150, water outlet diameter DN150, can provide a stable high-pressure fire water source, covering all production and living areas of the power station

Deluge fire extinguishing system: specially equipped with a large-flow deluge skid-mounted pump unit with water inlet diameter DN300, water outlet diameter DN250, specially designed for key fire prevention areas such as photovoltaic module areas and inverter rooms, and can respond quickly and effectively extinguish electrical fires

Intelligent control system: equipped with professional liquid level display cabinet and high-precision input pressure transmitter to realize real-time monitoring and automatic control of fire water level and pipe network pressure

Environmental guarantee system: Weteng industrial dehumidifiers are installed in the equipment room to effectively solve the impact of the high humidity environment in the south on electrical equipment and ensure stable operation of the system throughout the year.

Yunnan Mojiang Wenwucha Photovoltaic Complementary Photovoltaic Power Generation Project is a project of Yunnan Province "Fourteenth Five-Year Plan" Key new energy construction projects adopt "Generate electricity on the board and grow tea under the board" The compound development model achieves efficient utilization of land resources. The fire box and pump integration project undertaken by our company serves as the key to the safe operation of the power station. "patron saint", using energy-saving water pumps and intelligent control technology, while ensuring fire safety, minimizing operating energy consumption, and matching the project "Green, low carbon, sustainable" The development concept is highly consistent.

The successful delivery of this project once again demonstrates our company's technical strength and engineering quality in the field of fire box and pump integration. In the future, our company will continue to delve into the construction of fire protection systems in new energy, industry, municipal and other fields, and use more advanced technology, better products, and more professional services to protect the safe development of my country's green energy industry.
