Description

Technical Field

[0001] This utility model belongs to the technical field of automotive fire extinguishing equipment, specifically relating to an externally extending automotive chassis fire extinguishing device. Background Technology

[0002] Currently, the number of vehicles on the road is increasing, but the accumulation of new energy vehicle technology is insufficient, and the stability and reliability of electric systems still need to be gradually improved. Once a vehicle catches fire, the surface flames are easy to extinguish, but the areas under the chassis that are not easily observed are not easy to extinguish or cool down, which can easily lead to explosions or reignition, posing a threat to firefighting and rescue operations and on-site personnel. In view of this, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an externally extendable car chassis fire extinguishing device that can be folded and stored and can be extended into the bottom of the car to extinguish fires.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an externally extending automobile chassis fire extinguishing device, including a mobile integrated box and a chassis water spray frame. The chassis water spray frame is installed on the lower end of one side of the mobile integrated box and can be flipped towards the mobile integrated box. The chassis water spray frame includes multiple first water spray pipes, a water inlet pipe and a connecting pipe. One end of the multiple first water spray pipes is connected to the water inlet pipe, and the other end of the multiple first water spray pipes is connected to the connecting pipe. Multiple nozzle interfaces are formed on the multiple first water spray pipes at intervals.

[0005] Furthermore, the first water spray pipe has an outwardly extending nozzle mounting pipe formed on its side wall, and the nozzle interface is disposed on the upper surface of the nozzle mounting pipe.

[0006] Furthermore, there are three first water spray pipes, and the adjacent nozzle mounting pipes on the middle first water spray pipe face opposite directions.

[0007] Furthermore, reinforcing ribs are provided between adjacent first water spray pipes on the same chassis water spray frame.

[0008] Furthermore, a first hinge seat is formed on the side of the water inlet pipe facing the movable integrated box, and a second hinge seat is formed at the lower end of one side of the movable integrated box, and the first hinge seat and the second hinge seat are hinged to each other.

[0009] Furthermore, a reinforcing plate is fixedly connected to the upper end of the second hinge seat, the reinforcing plate extends toward either side of the second hinge seat, and a first pulley is provided on the lower surface of the reinforcing plate.

[0010] Furthermore, an inwardly extending mounting plate is fixedly connected to the upper surface of the connecting pipe, and a second pulley is provided on the lower surface of the mounting plate.

[0011] Furthermore, a first water inlet is formed on the side wall of the water inlet pipe, and a first water outlet is formed on the mobile integrated box. The first water outlet and the first water inlet are connected by a high-temperature resistant water pipe.

[0012] Furthermore, a second water spray pipe is connected between adjacent first water spray pipes, and multiple nozzle interfaces are formed on the second water spray pipe at intervals.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the chassis water spray frame is rotatably connected to the bottom of one side of the mobile integrated housing. In the folded state, the chassis water spray frame can be flipped upwards towards the side of the mobile integrated housing for storage, taking up less space. In the unfolded state, the chassis water spray frame flips to be parallel to the horizontal plane, and the mobile integrated housing moves, allowing the chassis water spray frame to extend into the chassis of the vehicle from the front or rear. Personnel activate the chassis water spray frame to spray water, and then withdraw from the rear side of the mobile integrated housing. Water flows into the inlet pipe of the chassis water spray frame and sprays out from the nozzles installed at the nozzle interfaces on the multiple first water spray pipes, cooling the car chassis and suppressing fire sources.

[0030] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0031] Example 1

[0032] like Figure 1 , Figures 9-12 As shown, this embodiment provides an externally extending vehicle chassis fire extinguishing device, including a mobile integrated housing 1 and a chassis water spray frame 2.

[0033] The mobile integrated cabinet 1 is driven by a motor, a common technology in the field, which will not be described in detail here. The mobile integrated cabinet 1 is used to house circuit boards, control panels, water tanks, and water tank valve assemblies, etc.

[0034] A base 11 is formed at the bottom of the integrated housing facing the chassis water spray frame 2. A first water outlet 15 is provided on the base 11. A water outlet frame 111 is provided on the upper surface of the base 11. Multiple nozzles 212 are provided on the side of the water outlet frame 111 facing the chassis water spray frame 2. A fireproof blanket is laid on the side of the water outlet frame 111 facing the mobile integrated housing 1 to prevent flames from shooting out and causing the temperature on the side of the mobile integrated housing 1 to be too high, which could cause injury to the operator.

[0035] The chassis water spray frame 2 includes two first water spray pipes 21, a water inlet pipe 22, and a connecting pipe 23. One end of each of the two first water spray pipes 21 is connected to the water inlet pipe 22. A first water inlet 221 is formed on the side wall of the water inlet pipe 22. The first water outlet 15 and the first water inlet 221 are connected through a high-temperature resistant water pipe. The other end of each of the two first water spray pipes 21 is connected to the connecting pipe 23. Four to six nozzle 212 interfaces are formed on each of the two first water spray pipes 21. Specifically, a nozzle mounting pipe 211 extending outward is formed on the side wall of the first water spray pipe 21. The nozzle 212 interface is located on the upper surface of the nozzle mounting pipe 211. A nozzle 212 is provided on the nozzle 212 interface. The nozzle 212 includes an annular conical surface and a flat surface. Multiple annular nozzles are provided on the annular conical surface, and nozzles are also provided on the flat surface. As shown in Figure 11, the solid cross-section circle represents the spray range, and the matrix dashed lines indicate the battery location area. This configuration significantly increases the spray range of the nozzle 212. In actual operation, the adjustment direction of the nozzle 212 is adjusted according to the optimal method at the moment. Preferably, the nozzle 212 is tilted, with a tilt angle of 42°-120°. The tilting of the nozzle 212 is achieved by setting an tilted nozzle 212 interface. Figure 12 As shown, the cross-section inside the triangle is the spraying area, and the tilted nozzle 212 increases the spraying area.

[0036] To ensure the stability of the chassis water spray frame 2, reinforcing ribs 24 are provided between adjacent first water spray pipes 21 on the same chassis water spray frame 2.

[0037] The chassis water spray rack 2 is installed on the lower end of one side of the mobile integrated box 1 and can be flipped towards the mobile integrated box 1. In this embodiment, the chassis water spray rack 2 has two states: when the chassis water spray rack 2 is flipped to the front of the integrated box 1, it is in a folded state; when the chassis water spray rack 2 is flipped to the bottom of the integrated box 1, it is in an unfolded state. Specifically, the water inlet pipe 22 has two spaced-apart first hinge seats 222 on the side facing the mobile integrated box 1, and two second hinge seats 13 are formed at the lower end of one side of the mobile integrated box 1. The second hinge seats 13 are located on the side of the seat body 11 facing the chassis spray frame 2. The first hinge seats 222 and the second hinge seats 13 are hinged to each other. The storage and placement of the chassis spray frame 2 can be turned over manually or by motor drive, depending on the actual situation. The water outlet frame 111 is provided with two locking pins 12 that are rotatably connected to its pipe body. The end face of the locking pin 12 is provided with a claw 121. The claw 121 has a notch. The connecting pipe 23 is fixed by deforming and inserting into the claw 121 through the notch. A reinforcing plate 14 is fixedly connected to the upper end of the second hinge seat 13. The reinforcing plate 14 is welded to the seat body 11. The reinforcing plate 14 extends to either side of the second hinge seat 13. Stable triangular plates extending upward and downward are formed at both ends of the reinforcing plate 14, respectively. A first pulley 141 is provided on the lower surface of the reinforcing plate 14. An inwardly extending mounting plate 231 is fixedly connected to the upper surface of the connecting pipe 23. A second pulley 232 is provided on the lower surface of the mounting plate 231. A triangular support is formed by the two first pulleys 141 and the one second pulley 232, which facilitates the movement of the chassis spray frame 2 after it is placed.

[0038] Example 2

[0039] like Figure 2 , Figures 9-12 As shown, the difference between this embodiment and Embodiment 1 is that the length of the water inlet pipe 22 and the connecting pipe 23 on the chassis water spray frame 2 is less than the length of the water inlet pipe 22 and the connecting pipe 23 on the chassis water spray frame 2 in Embodiment 1. There are two chassis water spray frames 2. By setting two chassis water spray frames 2, more water spray interfaces can be arranged, thereby setting more nozzles 212.

[0040] Example 3

[0041] like Figures 3-5 , Figures 9-12 As shown, the difference between this embodiment and embodiment 1 is that there are three first water spray pipes 21, and the adjacent nozzle mounting pipes 211 on the middle first water spray pipe 21 have opposite orientations.

[0042] Example 4

[0043] like Figure 6 , Figures 9-12As shown, the difference between this embodiment and embodiment 3 is that the length of the water inlet pipe 22 and the connecting pipe 23 on the chassis water spray frame 2 is less than the length of the water inlet pipe 22 and the connecting pipe 23 on the chassis water spray frame 2 in embodiment 3, and the number of chassis water spray frames 2 is two.

[0044] Example 5

[0045] like Figure 7 , Figures 9-12 As shown, the difference between this embodiment and embodiment 1 is that a second water spray pipe 25 is connected between adjacent first water spray pipes 21. Multiple nozzle 212 interfaces are formed on the second water spray pipe 25 at intervals. The installation of the second water spray pipe 25 can improve the stability of the overall chassis water spray frame 2 and increase the number of nozzles 212.

[0046] Example 6

[0047] like Figure 8 , Figures 9-12 As shown, the difference between this embodiment and embodiment 3 is that a second water spray pipe 25 is connected between adjacent first water spray pipes 21. Multiple nozzle 212 interfaces are formed on the second water spray pipe 25 at intervals. The installation of the second water spray pipe 25 can improve the stability of the overall chassis water spray frame 2 and increase the number of nozzles 212.
