[0079] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0080] The present application provides a fire prevention sprinkler system for a car charging and parking area.

[0081] like Figure 1 As shown, in one embodiment of the present application, a fire sprinkler system for a car charging and parking area includes a support frame 100, an early warning relay box 200, a booster pump 300, a fire extinguishing agent tank 400, a constant pressure pipe 500, a solenoid valve 600, a ground pipe 700, a top pipe 800 and a pressure gauge 900.

[0082] The support frame 100 includes a vertical column 110 and a horizontal beam 120 . The vertical column 110 is fixedly connected to the horizontal beam 120 . The vertical column 110 is perpendicular to the ground and is fixedly connected to the ground.

[0083] The early warning relay box 200 is hung on the vertical column 110 .

[0084] The booster pump 300 is electrically connected to the early warning relay box 200 , and an input end of the booster pump 300 is externally connected to a fire extinguishing agent pipeline network.

[0085] The input end of the fire extinguishing agent tank 400 is connected to the output end of the booster pump 300 .

[0086] The first end of the constant pressure tube 500 is connected to the output end of the fire extinguishing agent tank 400 .

[0087] The solenoid valve 600 includes a valve body 610 and a connecting three-way pipe 620. The first end of the connecting three-way pipe 620 is connected to the second end of the constant pressure tube 500, and the second end of the connecting three-way pipe 620 is connected to the input end of the valve body 610. The solenoid valve 600 is electrically connected to the early warning relay box 200.

[0088] The ground pipe 700 includes a pipe body 710 and a diverter tee pipe 720, the first end of the diverter tee pipe 720 is connected to the output end of the valve body 610, the second end of the diverter tee pipe 720 is connected to the pipe body 710, the first end 714 of the pipe body 710 is sealed, and the second end 715 of the pipe body 710 is provided with a plurality of normally open nozzles 730.

[0089] The top pipe 800 includes a vertical pipe 810 and a transverse pipe 820. The vertical pipe 810 is connected to the transverse pipe 820. The vertical pipe 810 is connected to the third end of the diversion three-way pipe 720. The transverse pipe 820 is parallel to the ground and is provided with a plurality of centrifugal nozzles 830.

[0090] The pressure gauge 900 is in conduction with the third end of the connecting three-way pipe 620 , and the pressure gauge 900 is electrically connected with the early warning relay box 200 .

[0091] Specifically, Figure 2 As shown, the lithium-based batteries of electric vehicles are mostly set at the bottom of the electric vehicle, and the conventional high-set sprinkler system is difficult to extinguish the fire in time and effectively, so a ground pipe 700 attached to the ground is set. When the external fire sensor detects the fire, the early warning relay box 200 gives the electromagnetic valve 600 an action level signal, the electromagnetic valve 600 is turned on, and the high-pressure fire extinguishing agent of the constant pressure tube 500 fills the ground pipe 700 and the top pipe 800. The ground pipe 700 performs a spray fire extinguishing operation on the bottom of the electric vehicle, and the top pipe 800 sprays the top of the electric vehicle to extinguish the fire. The top pipe 800 is fixedly connected to the support frame 100, so that the top pipe 800 realizes the fire extinguishing function on the roof. When the fire of the lithium-based battery of the electric vehicle spreads to the roof, the fire extinguishing system of the top pipe 800 can effectively contain the fire and prevent the fire from spreading to vehicles in adjacent parking spaces. It is worth mentioning that the booster pump 300 performs the operation of replenishing and pressurizing the fire extinguishing agent through the action level of the pressure gauge 900 relayed by the early warning relay box 200. The fire extinguishing agent tank 400 is used to store high-pressure fire extinguishing agent, so that the constant pressure pipe 500 connected thereto maintains a continuous high-pressure standby state.

[0092] It is worth mentioning that the fire sprinkler systems in car charging and parking places are mostly installed in parking spaces with charging piles.

[0093] The present application relates to a fire prevention sprinkler system for automobile charging and parking areas, which solves the defect that traditional fire extinguishing equipment is difficult to control fire in time.

[0094] like Figure 3 As shown, in one embodiment of the present application, the tube body 710 includes a connecting tube 711, a first drainage tube 712 and a second drainage tube 713. The connecting tube 711 is in communication with the output end of the valve body 610. The connecting tube 711 is in communication with the first drainage tube 712. The first drainage tube 712 is in communication with the second drainage tube 713.

[0095] In one embodiment of the present application, the size of the first drainage tube 712 is the same as the size of the second drainage tube 713. The length of the first drainage tube 712 is greater than or equal to 1.9 meters and less than or equal to 2.1 meters. The length of the connecting tube 711 is greater than or equal to 1 meter and less than or equal to 1.4 meters.

[0096] Specifically, the length of a general car is mostly less than 5.2 meters. The tube body 710 is attached to the ground, and is ten to twenty centimeters away from the bottom of the car. Through the three-section connecting pipe 711, the first drainage pipe 712 and the second drainage pipe 713, the tube body 710 can extend from the front of the car to the rear of the car.

[0097] The pipe body 710 divided into three pipes can be connected to multiple normally open nozzles 730. When the solenoid valve 600 is turned on, the normally open nozzles 730 conduct high-pressure fire extinguishing agent to achieve timely fire extinguishing work under the vehicle.

[0098] In one embodiment of the present application, the plurality of normally open nozzles 730 are respectively a first normally open nozzle 732, a second normally open nozzle 733 and a third normally open nozzle 734. The first normally open nozzle 732 is disposed between the connecting pipe 711 and the first drainage pipe 712. The second normally open nozzle 733 is disposed between the first drainage pipe 712 and the second drainage pipe 713. The third normally open nozzle 734 is disposed at an end of the second drainage pipe 713 away from the valve body 610.

[0099] Specifically, since the normally open nozzle 730 is 10 to 20 centimeters away from the bottom of the car, the distance between the normally open nozzles 730 can be selected to be greater than or equal to 1.9 meters and less than or equal to 2.1 meters, so that the sprayed fire extinguishing agent can cover as much area as possible under the car.

[0100] At the same time, as few normally open nozzles 730 as possible can keep the internal pressure of the fire extinguishing agent pipe network uniform and stable. The uniform and stable internal pressure of the fire extinguishing agent pipe network can achieve uniform distribution space of the fire extinguishing agent. At the same time, it can also prevent the booster pump 300 from supplying uneven pressure.

[0101] like Figure 5As shown, in one embodiment of the present application, the outer circumferential surfaces of the connecting pipe 711, the first drainage pipe 712 and the second drainage pipe 713 are all covered with a shock-absorbing belt 740. The thickness of the middle part of the shock-absorbing belt 740 is greater than the thickness of the two ends of the shock-absorbing belt 740. A through hole 741 is provided in the middle part of the shock-absorbing belt 740. The central axis of the through hole 741 is perpendicular to the ground. The first normally open nozzle 732, the second normally open nozzle 733 and the third normally open nozzle 734 are respectively provided in the through hole 741.

[0102] Specifically, the shock absorbing belt 740 can protect the pipe body 710 composed of the three sections of the connecting pipe 711, the first drainage pipe 712 and the second drainage pipe 713. In fact, the bottom of the shock absorbing belt 740 in the extension direction is provided with a strip groove, and the pipe body 710 is embedded in the strip groove.

[0103] More specifically, the bottom of the shock-absorbing belt 740 is provided with a through hole, and the connecting pipe 711, the first drainage pipe 712 or the second drainage pipe 713 are provided through the through hole. The cross section of the shock-absorbing belt 740 is a trapezoid. The cross section of the shock-absorbing belt 740 is a surface perpendicular to the end surface of the connecting pipe 711, the first drainage pipe 712 or the second drainage pipe 713. The length of the upper bottom of the cross section of the shock-absorbing belt 740 is less than the length of the lower bottom of the cross section of the shock-absorbing belt 740. The shock-absorbing belt 740 is provided with a through hole 741, and the through hole 741 passes through the top and bottom surfaces of the shock-absorbing belt 740, and the central axis of the through hole 741 is perpendicular to the ground. The first normally open nozzle 732, the second normally open nozzle 733 and the third normally open nozzle 734 are respectively arranged in the through hole 741.

[0104] It is worth mentioning that the normally open nozzle 730 protrudes from the tube body 710, so the shock-absorbing belt 740 needs to be separately provided with a through hole 741 to protect the normally open nozzle 730 and prevent the vehicle tire from rolling over it. At the same time, the through hole 741 can effectively open up a fire extinguishing agent injection channel.

[0105] In one embodiment of the present application, the shock-absorbing belt 740 is provided with a dust cover 742. The diameter of the dust cover 742 is smaller than the diameter of the through hole 741. An elastic layer 743 is provided at the edge of the dust cover 742. The dust cover 742 is clamped in the through hole 741. The elastic layer 743 is clamped between the dust cover 742 and the through hole 741.

[0106] Specifically, the dust cover 742 is clamped on the through hole 741 to prevent dust from clogging the normally open nozzle 730. In order to ensure that the fire extinguishing agent sprayed from the normally open nozzle 730 can flush the dust cover 742, the diameter of the dust cover 742 is smaller than the diameter of the through hole 741. The elastic layer 743 is clamped between the dust cover 742 and the through hole 741.

[0107] like Figure 4 As shown, in one embodiment of the present application, the horizontal pipe 820 includes a connecting pipe 821, a first conduit 822, a second conduit 823, and a third conduit 824. The connecting pipe 821 is in communication with the vertical pipe 810. The connecting pipe 821 is in communication with the first conduit 822. The first conduit 822 is in communication with the second conduit 823. The second conduit 823 is in communication with the third conduit 824. The connecting pipe 821, the first conduit 822, the second conduit 823, and the third conduit 824 are all in the same straight line.

[0108] Specifically, the height of the transverse pipe 820 from the ground meets the spray range index of the centrifugal nozzle 830. At this time, the reasonable distribution of the centrifugal nozzle 830 can effectively ensure the range and effectiveness of the area of ​​fire control. The connecting pipe 821, the first conduit 822, the second conduit 823, and the third conduit 824 are combined into the trunk of the transverse pipe 820. On the one hand, it can ensure that the centrifugal nozzle 830 extends from the front of the vehicle to the rear of the vehicle. On the other hand, it can provide a dispersed channel for the fire extinguishing agent that is more suitable for the fire situation.

[0109] In one embodiment of the present application, the transverse pipe 820 further includes a first branch pipe 825, a second branch pipe 826, a third branch pipe 827 and a fourth branch pipe 828. The first branch pipe 825 and the second branch pipe 826 are connected to each other. The first branch pipe 825 and the second branch pipe 826 are on the same straight line. The first branch pipe 825 is perpendicular to the first conduit 822. The first branch pipe 825, the second branch pipe 826, the first conduit 822 and the second conduit 823 are connected to the first connection point, and the first branch pipe 825, the second branch pipe 826, the first conduit 822 and the second conduit 823 are connected to each other at the first connection point 841. The third branch pipe 827 and the fourth branch pipe 828 are connected to each other. The third branch pipe 827 and the fourth branch pipe 828 are on the same straight line. The third branch pipe 827 , the fourth branch pipe 828 , the second conduit 823 , and the third conduit 824 are connected to the second connection point, and the third branch pipe 827 , the fourth branch pipe 828 , the second conduit 823 , and the third conduit 824 are interconnected at the second connection point 842 .

[0110] Specifically, the first branch pipe 825, the second branch pipe 826, the third branch pipe 827 and the fourth branch pipe 828 can focus the range of the fire extinguishing agent spread by the centrifugal nozzle 830 on the door side. In fact, when a lithium-based battery fails thermally, the spread of fire often spreads through the edge of the door first.

[0111] In one embodiment of the present application, the centrifugal nozzle 830 includes a first nozzle 831, a second nozzle 832, a third nozzle 833, a fourth nozzle 834, a fifth nozzle 835 and a sixth nozzle 836. The first nozzle 831 is disposed at the connection between the connecting pipe 821 and the first conduit 822. The second nozzle 832 is disposed at one end of the third conduit 824 away from the connecting pipe 821. The third nozzle 833 is disposed at one end of the first branch pipe 825 away from the first conduit 822. The fourth nozzle 834 is disposed at one end of the second branch pipe 826 away from the first conduit 822. The fifth nozzle 835 is disposed at one end of the third branch pipe 827 away from the second conduit 823. The sixth nozzle 836 is disposed at one end of the fourth branch pipe 828 away from the second conduit 823.

[0112] Specifically, the first nozzle 831 and the second nozzle 832 are mainly used to spray out the fire of the transformer equipment in the front hood of the car. The third nozzle 833, the fourth nozzle 834, the fifth nozzle 835 and the sixth nozzle 836 are mainly used to prevent the spread of fire, which often spreads first through the edge of the car door.

[0113] like Figure 3 As shown, in one embodiment of the present application, a secondary constant pressure tube 510 is provided between the third end of the connecting three-way tube 620 and the pressure gauge 900 .

[0114] Specifically, by adding a secondary constant pressure pipe 510, a plurality of adjacent parking spaces can share a booster pump 300, a fire extinguishing agent tank 400 and an early warning relay box 200, and electromagnetic valves 600, ground pipes 700 and top pipes 800 are laid in these adjacent parking spaces.

[0115] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0116] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the present application. It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
