Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, and in particular to a fire-fighting device for spontaneous combustion of batteries of new energy vehicles. Background Art

[0002] Electric vehicles mainly rely on their own battery packs to carry a large amount of energy to meet the power needs of the vehicle's own driving. However, when a large number of battery packs are stacked together, if an individual battery fails, it is easy to cause the entire battery pack to spontaneously combust or even fail, thereby threatening the personal safety and property safety of users.

[0003] Chinese patent document CN220917975U discloses a fire extinguishing device for spontaneous combustion of new energy vehicle batteries, which solves the problem that the current fire extinguishing method of fire extinguishers is not easy to act directly on the fire source from the bottom of the vehicle, and cannot reduce the oxygen content in the air around the fire source, resulting in low fire extinguishing efficiency. It includes a main pipe, the outer end of the main pipe is connected to a water inlet joint near the edge, and the outer end of the main pipe is sequentially embedded with a first four-way joint, a second four-way joint and a third four-way joint, and both ends of the first four-way joint are connected to a first branch pipe. The utility model connects the device to a high-pressure water device and moves it under the chassis of the vehicle. Each nozzle atomizes the high-pressure water and sprays it into a fine mist to cover the vehicle body and chassis. The mist droplets can quickly absorb heat and vaporize, reducing the temperature of the vehicle body. The mist droplets cover the surrounding of the vehicle body, displacing a large amount of air and reducing the oxygen content around the vehicle body, thereby effectively preventing the spread of combustion and achieving the purpose of fire extinguishing.

[0004] The existing technology has the following problems:

[0005] The fire extinguishing equipment uses a support rod installed on one side to drive the overall movement. However, since the component used for spraying is too long, it is difficult to control the overall direction when moving with the support rod, making it difficult to move the equipment to the bottom of the car, which may cause the equipment to collide with the front and rear side accessories of the bottom of the car.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 5 As shown, a fire extinguishing device for spontaneous combustion of new energy vehicle batteries includes a spraying section 1, the left end of the spraying section 1 is fixedly connected to the injection section 2, the right end of the spraying section 1 is fixedly connected to the blocking section 3, the bottoms of the injection section 2 and the blocking section 3 are fixedly connected to a mechanism plate 4, the lower sides of the two mechanism plates 4 are rotatably connected to two universal wheels 5 distributed front and back symmetrically, and the upper side of the mechanism plate 4 on the right side is fixedly connected to a control mechanism 6;

[0027] The control mechanism 6 includes a motor 61, the left side of which is fixedly connected to a boss on the upper side of the right mechanism plate 4 near the left front side, the output end of the motor 61 is fixedly connected to a right-angle reducer 62, the output end of the right-angle reducer 62 is fixedly connected to a winding disk 612, and the inner side of the winding disk 612 is wound with a cable 63.

[0028] It should be noted that the spraying section 1 is provided with multiple nozzles for spraying foam or water. The injection section 2 is L-shaped, which is used to facilitate the control of the movement of the equipment. At the same time, the connecting pipe is used to inject water or foam into the spraying section 1. The motor 61 drives the internal components of the right-angle reducer 62 to operate, and the right-angle reducer 62 drives the winding disk 612 to rotate. The winding disk 612 winds and stores the cable 63. There is a one-way component between the winding disk 612 and the right-angle reducer 62. When the cable 63 is pulled out from the inside of the winding disk 612, the winding disk 612 cannot drive the internal components of the right-angle reducer 62 to rotate in the opposite direction. When the winding disk 612 stores the cable 63, the right-angle reducer 62 can drive the winding disk 612 to rotate. A counterweight block is fixedly connected to the cable 63.

[0029] like Figure 4 、 Figure 5 As shown, a rotating seat 64 is rotatably connected to the upper side of the right mechanism plate 4 near the right rear side, and a control rod 65 is movably sleeved on the inner side of the rotating seat 64 .

[0030] It should be noted that the control rod 65 is used to facilitate the movement of the right end of the device. A limiting ring is fixedly connected to the upper side of the right mechanism plate 4 near the left rear side, which, together with the rotating seat 64, can limit the control rod 65 to maintain a horizontal state in the stored state.

[0031] like Figure 5 As shown, a clamping block 67 is movably sleeved in the upper mechanism hole of the control rod 65 , and the clamping block 67 is located on the left side of the rotating seat 64 , and a first spring 68 is fixedly connected to the lower side of the clamping block 67 .

[0032] It should be noted that the block 67 is used to limit the control rod 65, so that the control rod 65 cannot slide left and right on the inner side of the rotating seat 64. Pressing the block 67 allows the control rod 65 to slide left and right. When the control rod 65 slides out of the limiting ring, the control rod 65 can rotate.

[0033] like Figure 5As shown, an insert block 69 is slidably connected to the upper side of the right mechanism plate 4 near the rear side, and a limiting rod 610 is fixedly connected to the left side of the insert block 69. The outer side of the limiting rod 610 is movably sleeved in the vertical plate on the upper side of the right mechanism plate 4 near the left rear side, and the outer side of the limiting rod 610 is movably sleeved with a second spring 611, and the second spring 611 is located on the right side of the vertical plate. A socket is provided on the upper side of the right mechanism plate 4 near the right rear side, and the socket is located on the left side of the rotating seat 64.

[0034] It should be noted that when the left end of the control rod 65 is inserted into the insertion hole, the control rod 65 is in an oblique position at this time, and the insert block 69 is inserted into the fixing hole on the upper side of the control rod 65 near the left end, so that the state of the control rod 65 is fixed.

[0035] like Figure 5 As shown, the upper side of the block 67 is provided with cut corners near the left and right sides.

[0036] It should be noted that the setting of the cut angle allows the clamping block 67 to pass through the rotating seat 64 without being pressed down completely.

[0037] like Figure 4 、 Figure 5 As shown, limiting grooves 66 are provided on the front and rear sides of the outer side of the control rod 65 , and the inner convex strips of the rotating seat 64 are slidably connected to the inner sides of the limiting grooves 66 .

[0038] It should be noted that the limiting groove 66 is used to limit the state of the control rod 65 so that the control rod 65 can no longer rotate axially inside the rotating seat 64 .

[0039] like Figure 4 As shown, the control rod 65 is L-shaped.

[0040] It should be noted that the shape of the control rod 65 is used to facilitate control so that the force application position is located in the middle of the right side of the blocking section 3.

[0041] The working principle of the present invention is as follows: first, a plurality of nozzles are provided on the spraying section 1 for spraying foam or water; the injection section 2 is L-shaped for conveniently controlling the movement of the device; at the same time, a pipe is connected to inject water or foam into the spraying section 1; the motor 61 drives the internal components of the right-angle reducer 62 to operate; the right-angle reducer 62 drives the winding disk 612 to rotate; the winding disk 612 winds and stores the cable 63; there is a one-way component between the winding disk 612 and the right-angle reducer 62; when the cable 63 is pulled out from the inside of the winding disk 612, The winding disc 612 cannot drive the internal components of the right-angle reducer 62 to rotate in the reverse direction. When the winding disc 612 stores the cable 63, the right-angle reducer 62 can drive the winding disc 612 to rotate. A counterweight is fixedly connected to the cable 63. By pulling the cable 63 out from the inside of the winding disc 612, the injection section 2 is placed close to the front or rear of the car, and the counterweight on the cable 63 is used to swing the cable 63 from the bottom of the car to the other side of the car. Finally, the cable 63 is used to pull the device into the bottom of the car, which is convenient for the device. The placement of the cable 63 is convenient and quick. Finally, the control rod 65 is used to facilitate the movement of the right end of the device. The upper side of the right mechanism plate 4 near the left rear side is fixedly connected with a limiting ring, which cooperates with the rotating seat 64 to limit the control rod 65 to maintain a horizontal state in the stored state. The block 67 is used to limit the control rod 65, so that the control rod 65 cannot slide left and right on the inner side of the rotating seat 64. Pressing the block 67 allows the control rod 65 to slide left and right. When the control rod When 65 slides out of the restriction ring, the control rod 65 can be rotated, and the left end of the control rod 65 is inserted into the socket. The control rod 65 is in an oblique state at this time, and the insert block 69 is inserted into the fixing hole on the upper side of the control rod 65 near the left end, so that the state of the control rod 65 is fixed. The device is controlled to move forward and backward through the control rod 65 and the two sides of the injection section 2, so that the spraying section 1 can be made into a linear shape, avoiding the problem that the spraying section 1 is made into a surface shape in order to extinguish a large area of ​​flames, resulting in the overall shape being too large and difficult to store.
