A mobile fire pump for electric vehicle charging stations

Abstract

This invention discloses a mobile fire pump for electric vehicle charging stations, comprising a foundation, a roof, partition walls, and a charging box. The partition walls divide the foundation into several parking areas, and each parking area is equipped with a charging box containing a heat-sensing fire detector. The pump also includes a ground-rail fire suppression system, a hanging-rail fire suppression system, and a wall-mounted fire suppression system. By installing movable ground-rail and hanging-rail fire suppression systems within the parking areas, this invention enables simultaneous fire suppression operations on both the upper and lower parts of a burning electric vehicle. When a battery located inside the footrest catches fire, the hanging-rail fire suppression system can directly extinguish the fire. However, when a battery located inside the seat catches fire, the hanging-rail fire suppression system is difficult to activate quickly due to the obstruction of the seat. Therefore, the ground-rail fire suppression system can act on the battery through the gap between the rear wheel and the frame, enabling timely fire suppression in the early stages of a fire.

Description

Technical Field

[0001] This invention belongs to the field of fire safety technology, specifically a mobile fire pump for electric vehicle charging stations. Background Technology

[0002] Currently, many residential communities and factories have set up charging sheds for electric bicycles. These charging stations consist of a charging shed and several charging piles. Some of these charging sheds are located in open areas, while others are located in underground parking lots. As a result, many electric bicycles are placed in the charging sheds. When electric bicycles are charging, the batteries are prone to spontaneous combustion. When they are parked together, a chain reaction of fires can easily occur. If not dealt with in time, this can easily lead to a large-scale fire.

[0003] Chinese Patent Publication No. CN 114379395 B discloses a protective device for a charging station, including a base plate, a support frame mounted on the base plate, a plurality of charging piles mounted on the support frame, a charging control box electrically connected to the plurality of charging piles, and a protective canopy mounted on the support frame. The charging control box is installed on one side of the support frame outside. The side of the support frame near the charging piles is provided with a charging protection device to prevent electric vehicles from occupying the charging position when not charging and to protect the electric vehicles when charging. This protective device of the charging station achieves the function of protecting electric vehicles. At the same time, in the event of a fire, since the charging protection device is specifically located around the electric vehicle, it can quickly isolate the electric vehicle by spraying fire extinguishing agent. Furthermore, after the electric vehicle has reached the charging time, it prevents a fully charged electric vehicle from remaining at the charging pile, thus enabling the effective use of the charging pile.

[0004] The above-mentioned technical solutions collect and store rainwater during rainy days, spray water around the vehicle to cool it down when the air temperature is high, and extinguish fires with fire extinguishing agents in the event of a fire. However, the rainwater storage device has a limited storage capacity, and in summer, there are often continuous high temperatures, so the stored rainwater is simply not enough for cooling purposes. At the same time, the above solutions do not effectively isolate the electric vehicle battery. When the battery explodes, the flames spray a wide range, and the charging protection device alone cannot effectively block the fire.

[0005] Therefore, this application proposes a mobile fire pump for electric vehicle charging stations, which can effectively isolate the fire area in a timely manner to prevent the fire from spreading, and can also quickly spray water to extinguish the fire on the burning vehicle.

The end face of the first sliding part is provided with a threaded hole, and the end faces of the second sliding part and the third sliding part are both provided with through holes.

[0014] Preferably, a plurality of movable rings are slidably connected to the body of the second slide rod, and pipe clamps are fixedly connected to the surface of the movable rings, with the ground rail water supply pipe fixedly connected inside the pipe clamps.

[0015] Preferably, the suspended rail fire-fighting assembly includes a suspended rail, a moving block, a lead screw, a suspended rail nozzle, and a suspended rail water supply pipe. The suspended rail is fixedly connected to the top plate, the moving block is slidably connected to the surface of the suspended rail, and a strip groove is formed on the surface of the suspended rail.

The moving block is threadedly connected to the lead screw, and the suspended rail nozzle is fixedly connected to the lower part of the moving block and connected to the suspended rail water supply pipe.

[0016] Preferably, the wall-mounted fire protection component includes an adjustment mechanism embedded in the inner wall of the partition wall panel. The inner wall of the adjustment mechanism is rotatably connected to a plurality of partitions. Each partition is hollow and has a spray hole communicating with its interior on its surface. A rubber plug is fixedly connected to the lower end of each partition at the position of the spray hole on the next partition. A connecting ring is rotatably connected to the end of each partition.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention, by installing movable ground-rail fire extinguishing components and hanging-rail fire extinguishing components within the parking area, enables simultaneous fire suppression operations on a burning electric bicycle from both above and below. Since the batteries of electric bicycles are generally located inside the pedals or under the seat, when a battery located inside the pedals catches fire, the hanging-rail fire extinguishing component can directly extinguish the fire. However, when a battery located inside the seat catches fire, the hanging-rail fire extinguishing component is difficult to operate quickly due to the obstruction of the seat. Therefore, the ground-rail fire extinguishing component can act on the battery through the gap between the rear wheel and the frame, enabling timely fire suppression in the early stages of a fire.

[0022] 2. This invention installs wall-mounted fire-fighting components on the partition wall panels. When a vehicle catches fire in the corresponding parking area, the heat-sensing fire detector in the corresponding parking area alarms and controls the corresponding third servo motor to rotate through the built-in intelligent integrated management platform. This causes the partition doors on both sides of the parking area where the fire occurred to close, preventing the fire from spreading. At the same time, water is injected into the water supply ring through the water inlet pipe and finally sprayed downwards through the spray holes on the partition door, achieving the purpose of covering the entire parking area where the fire occurred and reducing the ambient temperature around the fire.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 11This invention provides a technical solution: a mobile fire pump for electric vehicle charging stations, comprising a foundation 1, a roof slab 2, a partition wall 3, and a charging box 4. The partition wall 3 divides the foundation 1 into several parking areas 5 for easy parking of electric vehicles. Each parking area 5 is equipped with a charging box 4, and each charging box 4 has multiple charging ports. A heat-sensing fire detector 6 is installed on the front of the charging box 4. The heat-sensing fire detector 6 adopts the WT-GL-100 distributed fiber optic linear heat-sensing fire detector host produced by Hebei Weitan Technology Co., Ltd., which has a built-in fiber optic temperature measurement module, an industrial control all-in-one computer, a touch screen display, and uses DC24V. Powered by a power supply, it features information display, temperature measurement, information storage, and fire alarm linkage functions. The signal processing unit is compact, easy to install, highly stable, and safe and reliable. The manufacturer provides a built-in intelligent AI integrated management platform. The foundation 1 and the top plate 2 are fixedly supported by a partition wall 3. It also includes a ground rail fire-fighting component 7, a hanging rail fire-fighting component 8, and a wall fire-fighting component 9. The ground rail fire-fighting component 7 is installed inside the foundation 1 and is used for fire extinguishing operations at the bottom of the electric vehicle. The hanging rail fire-fighting component 8 is suspended on the top plate 2 and is used for fire extinguishing operations at the top of the electric vehicle. The wall fire-fighting component 9 is installed on the partition wall 3 and is used for fire extinguishing operations in the entire fire-affected parking area 5.

[0038] Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, the ground rail fire-fighting assembly 7 includes a mounting block 701, a threaded rod 702, a first sliding rod 703, a slider 704, a ground rail water supply pipe 705, and a ground rail sprinkler head 706. The mounting block 701 is slotted and installed in the foundation 1. Rectangular slots 707 are provided on both sides of the mounting block 701. Sealing plates 708 are fixedly installed at both ends of the rectangular slots 707 by bolts. The threaded rod 702 and the first sliding rod 703 are respectively set in the two rectangular slots 707. One end of the threaded rod 702 is fixedly connected to a first servo motor 709, which is fixedly connected to the sealing plate 708. The other end of the threaded rod 702 is rotatably connected to the sealing plate 708. The first sliding rod 703 is fixedly connected to the two sealing plates 704. Between 8, a movable groove 710 is provided in the middle of the mounting block 701. An inclined groove 711 is provided between the movable groove 710 and the rectangular groove 707. The inclined groove 711 opens downward. A second sliding rod 712 is fixedly connected to the inner wall of the movable groove 710. A slider 704 is provided on the rod body of the threaded rod 702, the first sliding rod 703 and the second sliding rod 712. The slider 704 is threadedly connected to the threaded rod 702. The slider 704 is slidably connected to the first sliding rod 703 and the second sliding rod 712. The ground rail nozzle 706 is fixedly installed on the upper end of the slider 704. The ground rail nozzle 706 is connected to the ground rail water supply pipe 705. The ground rail water supply pipe 705 is spirally arranged on the second sliding rod 712.

[0039] By installing a ground rail fire-fighting component 7 on the foundation 1, when a fire occurs, the heat-sensing fire detector 6 detects the fire and controls the first servo motor 709 to start through its own intelligent AI integrated management system. This drives the threaded rod 702 to rotate, which in turn drives the slider 704 to move quickly to the parking area 5 where the heat-sensing fire detector 6 detected the fire. The ground rail water supply pipe 705 and the ground rail nozzle 706 installed on the slider 704 are used to spray water to extinguish the fire at the bottom of the burning electric vehicle.

[0040] Among them, such as Figure 6 As shown, the slider 704 includes a first sliding part 7041, a second sliding part 7042, a third sliding part 7043, and a connecting rod 7044. The second sliding part 7042 is fixedly connected to the first sliding part 7041 and the third sliding part 7043 through the connecting rod 7044. The end face of the first sliding part 7041 is provided with a threaded hole, and the end faces of the second sliding part 7042 and the third sliding part 7043 are provided with through holes. The first sliding part 7041 and the third sliding part 7043 are located in the rectangular grooves 707 on both sides of the mounting block 701, and the second sliding part 7042 is located in the moving groove 710. The two connecting rods 7044 slide in the inclined groove 711. The inclined groove 711 opens downward, which can effectively prevent rainwater from entering the rectangular groove 707.

[0041] Among them, such as Figure 11 As shown, several movable rings 713 are slidably connected to the body of the second sliding rod 712. Pipe clamps 714 are fixedly connected to the surface of the movable rings 713. The ground rail water supply pipe 705 is fixedly connected inside the pipe clamp 714. The ground rail water supply pipe 705 is fixed at intervals on the pipe clamp 714. When the slider 704 moves, it pulls the ground rail water supply pipe 705 to move, which serves to straighten the ground rail water supply pipe 705 and prevent the ground rail water supply pipe 705 from getting tangled.

[0042] Specifically, such as Figure 1 , Figure 5 and Figure 7 As shown, the suspended rail fire-fighting assembly 8 includes a suspended rail 801, a moving block 802, a lead screw 803, a suspended rail nozzle 804, and a suspended rail water supply pipe 805. The suspended rail 801 is fixedly connected to the top plate 2, and the moving block 802 is slidably connected to the surface of the suspended rail 801. A strip groove 806 is formed on the surface of the suspended rail 801. A second servo motor 807 is fixedly installed at one end of the strip groove 806. The output end of the second servo motor 807 is fixedly connected to one end of the lead screw 803, and the other end of the lead screw 803 is rotatably connected to the inner wall of the strip groove 806. The moving block 802 is threadedly connected to the lead screw 803. The suspended rail nozzle 804 is fixedly connected to the lower part of the moving block 802, and the suspended rail nozzle 804 is connected to the suspended rail water supply pipe 805.

[0043] By installing a suspended rail fire-fighting component 8 on the top plate 2, when a fire occurs, the heat-sensing fire detector 6 detects the fire and controls the second servo motor 807 to start through its own intelligent AI integrated management system, which drives the lead screw 803 to rotate, thereby causing the moving block 802 to move along the suspended rail 801 to the parking area 5 where the fire occurred, and then using the suspended rail water supply pipe 805 and the suspended rail nozzle 804 to spray water to extinguish the fire on the electric vehicle.

[0044] Specifically, such as Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the wall-mounted fire-fighting component 9 includes an adjustment mechanism 901 embedded in the inner wall of the partition wall panel 3. Several partition panels 902 are rotatably connected to the inner wall of the adjustment mechanism 901. The adjustment mechanism 901 controls the rotation of the partition panels 902, facilitating timely isolation of the burning storage area 5 and preventing the spread of fire. Each partition panel 902 has a hollow structure, and its surface has spray holes 903 communicating with its interior. A rubber plug 907 is fixedly connected to the lower end of each partition panel 902 at the position corresponding to the spray hole 903 on the next partition panel 902. A connecting ring 908, also hollow, is rotatably connected to the end of each partition panel 902. For example... Figure 8 As shown, when the partition 902 is rotated to the fire extinguishing state, the spray holes 903 on the side facing away from the fire-damaged parking area 5 are blocked by rubber plugs 907 to prevent water leakage, and the spray holes 903 on the side facing the fire-damaged parking area 5 begin to spray water into the entire parking area 5 to cool it down. Compared with traditional fire sprinkler heads on the ceiling, the spray holes 903 are more densely distributed and have a larger water output.

[0045] Among them, such as Figure 8 As shown, the adjustment mechanism 901 includes an installation strip 9011 fixedly installed on the inner wall of the partition wall panel 3. A third servo motor 9012 is fixedly installed at the top of the installation strip 9011. A transmission shaft 9013 is rotatably connected to the inner wall of the installation strip 9011. A first bevel gear 9014 is fixedly installed on the surface of the transmission shaft 9013. The two ends of the partition page 902 extend into the two installation strips 9011 respectively, and a second bevel gear 9015 is fixedly installed thereon. The first bevel gear 9014 and the second bevel gear 9015 mesh with each other. A connecting ring 908 is sleeved on the shaft of the transmission shaft 9013, and a water inlet 9016 is opened at the corresponding position of the transmission shaft 9013. The third servo motor 9012 is controlled by the intelligent AI intelligent integrated management system to drive the transmission shaft 9013 to rotate. Through the transmission of the first bevel gear 9014 and the second bevel gear 9015, the partition page 902 rotates, thereby achieving the purpose of isolating the fire storage area 5.

[0046] Among them, such as Figure 10As shown, a water supply ring 904 is rotatably connected to the end of the drive shaft 9013. A water inlet pipe 905 is fixedly connected to the surface of the water supply ring 904. A water inlet hole 906 is opened inside the water supply ring 904 on the drive shaft 9013. After the water in the water inlet pipe 905 enters the water supply ring 904, it enters the drive shaft 9013 through the water inlet hole 906, then enters the partition page 902 through the connecting ring 908, and finally sprays out through the spray hole 903 to achieve the purpose of regional cooling.

[0047] Specifically, such as Figure 4 As shown, two limiting rods 10 are provided on the surface of the foundation 1. The two limiting rods 10 are connected to the ground through a telescopic cylinder 11, and a return spring 12 is sleeved on the surface of the telescopic cylinder 11. When the electric vehicle is parked, the front wheel is placed between the two limiting rods 10, which can simply restrict the parking position of the electric vehicle and facilitate the ground rail fire-fighting component 7 to pass through the bottom of the electric vehicle.

[0048] Specifically, all water inlet pipes 905 on each partition wall panel 3 are supplied with water by a main water pipe, and a solenoid valve is installed on the main water pipe. The ground rail water supply pipe 705, the hanging rail water supply pipe 805 and the main water pipe are all supplied with water by a unified water supply base station, and a water pump is installed. The solenoid valve and the water supply base station are all controlled by a unified intelligent AI integrated management system.
