Description

Technical Field

[0001] This invention relates to the field of new energy fire extinguishing technology, and in particular to a rotary hydraulically driven fire extinguishing device for new energy vehicles. Background Technology

[0002] New energy vehicles refer to vehicles that use unconventional fuels as their power source and integrate advanced technologies in vehicle power control and drive. New energy vehicles mainly include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Due to structural limitations, the battery pack located at the bottom of the chassis of new energy vehicles is prone to fire in the event of a collision. Once a fire occurs, traditional fire extinguishing methods cannot directly target the ignition point, resulting in a significant reduction in fire extinguishing effectiveness.

[0004] Currently, the fire extinguishing method involves directly injecting high-pressure water into the ignition point. However, this method requires the spray nozzle to be inserted under the vehicle, which greatly limits the operation. When directly spraying water to extinguish the fire, a large amount of water vapor is generated and overflows in all directions, making it impossible to accurately observe the fire status. Moreover, the fire extinguishing efficiency is also very limited. Summary of the Invention

[0005] The technical problem that this invention aims to solve is that current fire extinguishing methods require the spray nozzle to be inserted under the vehicle, which greatly limits the operation. When directly spraying to extinguish the fire, a large amount of water vapor is generated and overflows in all directions, making it impossible to accurately observe the fire status, and the fire extinguishing efficiency is also very limited.

[0006] The technical solution adopted by this invention to solve its technical problem is: a rotating hydraulically driven fire extinguishing device for new energy vehicles, including a main frame and an external connecting pipe installed on the outer side of the main frame for connecting a high-pressure water pipe. A centrally mounted adjusting plate is movably assembled inside the main frame. A horizontally placed water guide pipe is fixed on the upper surface of the centrally mounted adjusting plate. An annular sinking and closing groove for installing the centrally mounted adjusting plate is opened on the inner side of the main frame. An annular driving groove is opened on the inner side of the annular sinking and closing groove. Laterally driven blades are provided on the outer arc surface of the centrally mounted adjusting plate. A centrally mounted liquid injection pipe with an upward protrusion is provided at the middle of the inner bottom surface of the main frame. Spray angle adjustment covers with externally mounted high-pressure water nozzles are installed on the outer walls on both sides of the horizontally placed water guide pipe.

[0007] The lower outer side of the main frame is equipped with a height-adjustable support leg, and the lower outer side of the height-adjustable support leg is movably fitted with a bottom drive wheel.

[0008] The central regulating plate has an internal flow channel. One end of the internal flow channel is connected to the interior of the horizontal water pipe, and the other end of the internal flow channel is connected to the central injection pipe. The central regulating plate is sleeved on the outside of the central injection pipe through the internal flow channel and is movably connected to the central injection pipe.

[0009] The horizontal water guide pipe is provided with lateral assembly through holes on both sides. The spray angle adjustment cover includes an outer assembly cover that is sleeved and fixed at the opening position of the lateral assembly through hole, an arc-shaped flow guide fixed on the outside of the outer assembly cover, and a horizontal outer cover fixed at the liquid outlet position of the arc-shaped flow guide. The outer side of the horizontal outer cover is provided with a side mounting hole for installing a high-pressure water nozzle.

[0010] An external flow control valve body with an internally installed electronic control valve is fixed on the outer side of the main frame at the connection end of the external connecting pipe.

[0011] The main frame has a lateral tilting groove on its outer side. The height-adjustable support includes a tilting adjustment arm that is movably inserted into the outer side of the main frame via a side mounting shaft, a linkage control shaft that is movably mounted on the outer side of the tilting adjustment arm, a transverse rotating shaft that is movably mounted on the outer end of the tilting adjustment arm for connecting the bottom drive wheel, a built-in linkage shaft that is movably mounted inside the tilting adjustment arm, and a hydraulic drive support rod that is mounted between the main frame and the tilting adjustment arm.

[0012] The hydraulically driven strut is inserted into the main frame through a lateral connecting pipe and is movably assembled with the main frame.

[0013] A transmission gear set is provided between the linkage control shaft and the built-in linkage shaft, and between the horizontal rotation shaft and the built-in linkage shaft. An external drive impeller is fixedly mounted on the outer side of the linkage control shaft.

[0014] The linkage control shaft and the horizontal rotation shaft are connected by a built-in linkage shaft transmission.

[0015] The outer surface of the external assembly cover is threaded with a lateral locking bolt.

[0016] The beneficial effects of this invention are:

[0017] (1) The rotating water-driven fire extinguishing device for new energy vehicles of the present invention uses water-driven driving, which does not require additional power driving and greatly improves safety.

[0018] (2) High-pressure water can not only drive the bottom drive wheel, but also control the rotation of the central adjustment plate, thereby adjusting the angle and position of the horizontal water guide pipe. The spray angle adjustment cover is attached to both sides of the horizontal water guide pipe so that the angle and position of the high-pressure water nozzle can be changed, greatly improving the applicable range and operability.

[0019] (3) By using an oblique spraying method, high-temperature smoke can be discharged outside the vehicle at a fixed point and in a directional manner, which greatly improves the fire extinguishing effect;

[0020] (4) The entire device adopts a split structure design, which not only facilitates later maintenance and replacement, but also reduces the cost of use;

[0021] (5) Height-adjustable support legs are installed on the main frame, which can not only adjust the bottom clearance of the main frame, but also make it adaptable to various models;

[0022] (6) An electronic control valve is installed on the outside of the main frame at the connection end of the external connecting pipe. This not only makes it convenient to adjust the direction of high-pressure water flow, but also adopts a long-distance structural design, which greatly improves the safety of the adjustment equipment.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4The rotating hydraulically driven fire extinguishing device for new energy vehicles shown includes a main frame 1 and an external connecting pipe 2 installed on the outer side of the main frame 1 for connecting a high-pressure water pipe. A centrally mounted adjusting plate 3 is movably installed inside the main frame 1. A horizontally mounted water guide pipe 4 is fixed on the upper surface of the centrally mounted adjusting plate 3. An annular sinking closure groove 5 for installing the centrally mounted adjusting plate 3 is opened on the inner side of the main frame 1. An annular drive groove 6 is opened on the inner side of the annular sinking closure groove 5. Lateral drive blades 7 are provided on the outer arc surface of the centrally mounted adjusting plate 3. A centrally mounted liquid injection pipe 8 with an upward protrusion is provided at the middle of the inner bottom surface of the main frame 1. Spray angle adjustment covers 10 with externally mounted high-pressure water nozzles 9 are installed on the outer walls on both sides of the horizontally mounted water guide pipe 4.

[0031] To accommodate bottom height adjustment and drive, a height-adjustable support leg 11 is installed on the lower outer side of the main frame 1, and a bottom drive wheel 12 is movably mounted on the lower outer side of the height-adjustable support leg 11.

[0032] In order to facilitate internal flow, the central regulating plate 3 has an internal flow channel 13. One end of the internal flow channel 13 is connected to the interior of the horizontal water pipe 4, and the other end of the internal flow channel 13 is connected to the central injection pipe 8. The central regulating plate 3 is sleeved on the outside of the central injection pipe 8 through the internal flow channel 13 and is in movable communication with the central injection pipe 8.

[0033] To facilitate the flow from both sides, the horizontal water guide pipe 4 is provided with lateral assembly through holes on both sides. The spray angle adjustment cover 10 includes an outer assembly cover 101 that is sleeved and fixed at the opening of the lateral assembly through hole, an arc-shaped flow guide cover 102 fixed on the outside of the outer assembly cover 101, and a horizontal outer cover 103 fixed at the outlet of the arc-shaped flow guide cover 102. A side mounting hole for installing the high-pressure water nozzle 9 is provided on the outer surface of the horizontal outer cover 103.

[0034] In order to facilitate external adjustment, an external flow control valve body 15 with an internally installed electronic control valve 14 is fixed on the outer side of the main frame 1 at the connection end of the external connecting pipe 2.

[0035] The electronic control valve 14 is existing technology, which adjusts the internal flow direction by rotating it.

[0036] To facilitate height adjustment and drive, a lateral tilting groove is provided on the outer side of the main frame 1. The height-adjustable support leg 11 includes a tilting adjustment arm 111 that is movably inserted into the outer side of the main frame 1 via a side mounting shaft, a linkage control shaft 112 that is movably mounted on the outer side of the tilting adjustment arm 111, a transverse rotation shaft 113 that is movably mounted on the outer end of the tilting adjustment arm 111 for connecting the bottom drive wheel 12, a built-in linkage shaft 114 that is movably mounted inside the tilting adjustment arm 111, and a hydraulic drive support rod 115 that is installed between the main frame 1 and the tilting adjustment arm 111.

[0037] The hydraulically driven strut 115 consists of a hydraulic cylinder movably mounted on the main frame 1, a piston rod slidably mounted inside the hydraulic cylinder, and a return spring fitted on the outside of the piston rod. A lateral internal threaded through hole for mounting an internal closing bolt is provided on the outer side of the hydraulic cylinder, allowing adjustment of the extension and retraction length of the hydraulically driven strut 115 from the outside. This adjusts the bottom clearance of the main frame 1.

[0038] To facilitate movement and telescopic adjustment, the hydraulically driven strut 115 is inserted into the main frame 1 via a lateral connecting pipe and is movably assembled with the main frame 1.

[0039] To facilitate meshing transmission, a transmission connecting gear set 116 is provided between the linkage control shaft 112 and the built-in linkage shaft 114, and between the transverse rotating shaft 113 and the built-in linkage shaft 114. An external drive impeller 117 is fixedly mounted on the outer side of the linkage control shaft 112.

[0040] High-pressure water is injected into the main frame 1 through the external high-pressure water pipe 2. Then, the high-pressure water is introduced through the electronic control valve 14 to impact the external drive impeller 117, causing the external drive impeller 117 to rotate, thereby controlling the linkage control shaft 112 to rotate. The linkage control shaft 112 drives the internal linkage shaft 114 to rotate through the transmission connection gear set 116. The internal linkage shaft 114 then drives the transverse rotating shaft 113 to rotate through the transmission connection gear set 116 on the other side. Then, the transverse rotating shaft 113 drives the bottom drive wheel 12 to rotate, and the bottom drive wheel 12 drives the entire main frame 1 to move.

[0041] The main frame 1 is divided into four independent chambers by partitions. One is connected to the inside of the hydraulic drive strut 115, one is connected to the inside of the external drive impeller 117, one is connected to the inside of the central injection pipe 8, and one is connected to the inside of the annular drive groove 6. The external connecting pipe 2 adjusts the connection state with the chambers by rotating the electronic control valve 14.

[0042] To facilitate the transmission connection, the linkage control shaft 112 and the horizontal rotation shaft 114 are connected by a built-in linkage shaft 115.

[0043] In order to adjust and lock the angle of the spray angle adjustment cover 10, a lateral locking bolt 104 is threaded on the outer side of the outer mounting cover 101.

[0044] Lateral limiting blind holes arranged in a ring array are provided at both ends of the outer side of the horizontal water guide pipe 4. The spray angle adjustment cover 10 is fixed and locked to the outside of the horizontal water guide pipe 4 by inserting the lateral locking bolt 104 into the lateral limiting blind hole.
