Technical Field
[0001] The utility model relates to the technical field of fire fighting, and in particular to an underground fire fighting system for new energy vehicles. Background Art
[0002] With the continuous promotion of new energy vehicles, the fire protection problem of new energy vehicle fires has received more and more attention. When a new energy vehicle catches fire, traditional fire extinguishers are limited in effect and can only be put out with a large amount of fire water. Especially when a car catches fire in a parking space, the fire can easily spread to other parking spaces, causing serious property losses. Existing garage fire sprinklers are generally on the ceiling, while new energy vehicles usually catch fire in the bottom battery compartment, and fire sprinklers cannot effectively extinguish the fire. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figures 1 to 4 As shown, the embodiment of the utility model provides an underground fire protection system for new energy vehicles, including a temperature detector, a fire branch pipe, a fire sprinkler group, a fire main pipe 2, and a fire sensor valve 9. Among them:
[0026] The temperature detector is used to detect the ambient temperature of the parking space and can be installed on the wall near parking space 1.
[0027] The fire branch pipe is buried under the ground of parking space 1.
[0028] The fire sprinkler group is connected to the fire branch pipe and the nozzles of the fire sprinkler group are connected to the ground. Figure 1 , Figure 3 , Figure 4 As shown, the fire sprinkler group includes adjacently arranged vertical fire sprinkler 6 and inclined fire sprinkler 7. The vertical fire sprinkler 6 is arranged around the parking space 1, and the inclined fire sprinkler 7 is arranged on the side of the vertical fire sprinkler 6 close to the parking space 1, and the nozzle of the inclined fire sprinkler 7 is arranged toward the parking space 1. Fire water is sprayed through the vertical fire sprinkler 6 to form a fire water curtain in the parking space 1 to prevent the fire from spreading to other parking spaces. Fire water is sprayed to the bottom of the new energy vehicle through the inclined fire sprinkler 7 to extinguish fires in key areas such as the battery compartment.
[0029] The fire main pipe 2 is arranged outside the parking space 1 and is connected with the fire branch pipe.
[0030] The fire sensing valve 9 is arranged between the fire main pipe 2 and the fire branch pipe, and is connected to the temperature detector. When a fire occurs in the parking space, the fire sensing valve 9 receives the fire sensing signal from the temperature detector and opens the valve, so that the fire water in the fire main pipe 2 enters the fire branch pipe and is sprayed out through the fire sprinkler group.
[0031] As a preferred implementation, there are multiple fire sprinkler groups, and the multiple fire sprinkler groups are arranged along the periphery of the parking space.
[0032] As a preferred implementation, Figure 1 and Figure 2 As shown, a pair of inclined fire sprinklers 7 with nozzles facing in opposite directions are also provided in the center of the parking space, and the nozzles of the pair of inclined fire sprinklers 7 are oriented parallel to the length direction of the parking space. The pair of inclined fire sprinklers 7 in the center of the parking space can extinguish fires at the bottom of the vehicle, especially at key locations such as the charging compartment. In actual applications, the number of fire branch pipes and corresponding sprinklers can be increased according to different vehicle models.
[0033] As a preferred implementation, Figure 4 As shown, the nozzle of the fire sprinkler group is an elliptical pot mouth, which can simply pressurize the fire water and spray it over a larger range to increase the fire fighting effect.
[0034] As a preferred embodiment, a cover 8 is movably connected to the nozzle of the fire sprinkler group, such as the cover 8 connected by a hinge, the cover 8 connected by an ear plate and a pin shaft, etc. Under normal circumstances, the cover 8 remains closed to prevent foreign objects from clogging the fire hose. When a fire occurs, the fire water is pressurized through the elliptical fire sprinkler group of the pot mouth. Under the action of the water pressure, the cover 8 of the nozzle of the fire sprinkler group is pushed open, and the fire water is sprayed out.
[0035] As a preferred embodiment, the fire branch pipe includes a longitudinal fire branch pipe 4 arranged along the length direction of the parking space and a transverse fire branch pipe 5 arranged along the width direction of the parking space, and the longitudinal fire branch pipe 4 and the transverse fire branch pipe 5 are connected.
[0036] As a preferred embodiment, the temperature detector is also connected to the charging pile 3. When a fire occurs, the charging pile 3 receives the fire sensing signal from the temperature detector and cuts off the power to prevent electric shock.
[0037] When a fire occurs in a parking space, the temperature detector detects the temperature of the environment in the parking space and transmits the fire sensing signal to the fire sensing valve 9 and the charging pile 3 in the corresponding parking space. The valve 9 of the fire sensing valve opens, and the fire water in the fire main pipe 2 flows into the longitudinal fire branch pipe 4 and the horizontal fire branch pipe 5 in the parking space, and the water is simply "pressurized" and sprayed out through the special nozzle of the fire sprinkler group. Under the action of water pressure, the cover of the nozzle of the fire sprinkler group is pushed open and the fire water is sprayed out. The fire water sprayed by the vertical fire sprinkler 6 forms a fire water curtain in the parking space 1 to prevent the fire from spreading to other parking spaces. The inclined fire sprinkler 7 at the bottom of the vehicle body (i.e., a pair of inclined fire sprinkler 7 set in the center of the parking space) and the inclined fire sprinkler 7 tilted inward on all sides spray to the bottom of the new energy vehicle, effectively extinguishing the fire at the bottom of the vehicle body, especially extinguishing the fire at key parts such as the battery compartment. At the same time, the charging pile 3 is powered off after receiving the fire sensing signal, and electric shock is prevented while extinguishing the fire.
[0038] All fire-fighting facilities of the utility model are pre-buried underground, do not occupy the garage space above ground, have no impact on the vehicles entering and exiting, and can realize automatic fire-fighting of open-air parking spaces. The utility model can effectively deal with the parking and charging fire problems of new energy vehicles through special nozzles and arrangement methods, especially for extinguishing fires in the battery compartments of new energy vehicles, which has advantages that traditional fire-fighting methods cannot match, and the combined arrangement of nozzles can effectively control the spread of fire and avoid causing greater property losses. The utility model cuts off the power to the charging pile while extinguishing the fire, and prevents electric shock accidents while extinguishing the fire.

Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
