Description

Technical Field

[0001] The utility model relates to the technical field of fire protection of new energy vehicle charging stations, in particular to an automatic fire protection sprinkler device. Background Art

[0002] In recent years, with the popularity of electric vehicles, the construction of charging stations has also grown rapidly. Due to factors such as battery heating and improper operation during the fast charging process of electric vehicles, accidents of charging piles or charging vehicles catching fire are also frequent. Most charging stations are unmanned. In order to control the fire in time, reduce economic losses and improve safety when a fire occurs, sprinkler devices are installed near the charging piles to extinguish the fire in time. At present, the common charging pile sprinkler devices are sprinkler heads and sprinkler pipes. When a fire occurs, the sprinkler head sprays water on the charging vehicle to extinguish the fire. For example, an automatic fire sprinkler device for a charging pile with application number CN202320516069.4 includes a sprinkler pipe and several sprinkler heads evenly installed at the lower end of the sprinkler pipe. One end of the sprinkler pipe is fixedly connected to a mixing pipe, and a group of buckles are installed on the outside of the sprinkler pipe, and a lifting frame is installed on the upper end of each buckle. Although the above common types of automatic sprinkler devices can be raised and lowered to adjust the spray height and control the spray range, the following problems still exist:

[0003] Since the probability of fire in charging piles is relatively low, the sprinkler device is idle for a long time, and rust or moss will appear in the sprinkler pipes. In addition, groundwater is mostly used for sprinkler water. Once a fire occurs, these impurities can easily clog the fire sprinkler head, making it impossible to spray and extinguish the fire in a timely and efficient manner. Only adding a filtering structure at the water inlet is not convenient for disassembly, cleaning and maintenance. At the same time, since the length of electric vehicles is usually around 4-5 meters, and the charging piles have a large front and rear span, after a fire occurs, the sprinkler device is fixed in position and cannot be sprayed and extinguished in a targeted manner. Not only does it consume a lot of water, but the fire extinguishing is also not timely and efficient. Utility Model Content

[0004] The utility model aims to provide an automatic fire sprinkler device to solve the problems in the prior art that the sprinkler head of the existing sprinkler device is easily blocked and difficult to clean, and the sprinkler device is fixed in position and cannot perform targeted spraying and fire extinguishing.

[0008] Preferably, a sealing gasket is fixedly provided on the top of the inner wall of the internal threaded sealing cap, an inner pad is fixedly provided on the inner side wall of the straight-through pipe, and the top of the filter screen cylinder is arranged opposite to the oblique-through pipe, so as to facilitate regular cleaning and maintenance.

[0009] Preferably, a solenoid valve is fixedly installed in the middle of the water supply hose, so that automatic sprinkler fire extinguishing can be achieved.

[0010] Preferably, the spray slide is slidably arranged on the spray rack; the spray fire can be extinguished in a targeted manner, thereby improving the fire extinguishing efficiency and reducing the waste rate of water resources.

[0011] Preferably, assembly frames are fixedly provided at both ends of the spray frame to facilitate installation of the spray frame on the charging carport.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
