[0016] 1. A fire-fighting robot for new energy vehicles. By setting up a small car and a fire-fighting device, after the vehicle catches fire, the fire-fighting device and the controller are connected through a soft water pipe and a soft air pipe. The small car is controlled by a remote control to move to the bottom of the new energy vehicle (under the battery), and the gas source valve on the gas tank is opened. The gas passes through the soft air pipe and the air outlet pipe in turn and is discharged. The air pressure is used to puncture the battery of the faulty vehicle.

[0017] 2. A new energy vehicle fire-fighting robot, by setting branch pipes, when water flows through the branch pipes, the recoil force formed by the water at the first bend drives the branch pipes and the upper cylinder to rotate as a whole, and the water sprayed from multiple branch pipes can form a conical partition, which can effectively isolate the outside air from entering the partition, thereby accelerating the oxygen consumption in the partition, thereby improving the fire-fighting efficiency, and because the branch pipes are rotating, the recoil forces in various directions on the trolley are balanced and balanced, thereby preventing the trolley from being easily tipped over by the recoil force from a certain direction, and the cooperation between the branch pipes and the main pipe increases the water coverage area, improves the fire-fighting efficiency, and the recoil force formed by the water at the second bend is downward, which can make the trolley more stable on the ground, thereby preventing the trolley from tipping over due to the recoil force.

[0018] 3. A new energy vehicle fire-fighting robot, which is equipped with a material box. After the gate valve assembly is opened, water enters the material box from the first pipe, and the water is mixed with a foaming agent and flows into the water collecting cylinder from the second pipe. A large amount of foam is formed and sprayed out under the action of the water flow, thereby improving the fire-fighting effect.

[0019] 4. A fire-fighting robot for new energy vehicles is provided with an outer guide ring. Water and a foaming agent are mixed and flow into the outer guide ring from the second pipe, then flow into the inner guide ring through the circular hole, and then flow into the cylinder through the third pipe, and then follow the water flow to be sprayed out from the main pipe, so that the foam is not sprayed out through the branch pipe, avoiding the influence on the barrier formed by the water of the branch pipe. When the upper cylinder is rotating, the foaming agent and water are fully stirred through the rotating circular hole to quickly generate foam.

[0020] 5.

Implementation

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0033] Reference Figure 1-7 A new energy vehicle fire-fighting robot comprises a trolley 1, a fire-fighting device installed on the trolley 1, and a remote controller 2 for wirelessly controlling the trolley 1. The top of the trolley 1 is provided with a mounting groove 6. The fire-fighting device comprises a water collecting cylinder fixed in the mounting groove 6. A main pipe 9 is arranged on the top of the water collecting cylinder. A water inlet pipe 10 and an air outlet pipe 11 are arranged on the side of the water collecting cylinder, both of which have input ends passing through the trolley 1. The water inlet pipe 10 is communicated with the water collecting cylinder, and the output end of the air outlet pipe 11 passes through the main pipe 9. A replaceable gas tank 3 is installed on the remote controller 2. A soft air pipe 4 is passed between the gas tank 3 and the air outlet pipe 11. The input end of the water inlet pipe 10 is connected to a soft water pipe 5 for connecting to a water source. After a vehicle catches fire, the fire extinguishing device and the controller are connected through the soft water pipe 5 and the soft air pipe 4. The remote controller 2 is used to control the trolley 1 to move to the bottom of the new energy vehicle (under the battery). The gas source valve on the gas tank 3 is opened, and the gas passes through the soft air pipe 4 and the air outlet pipe 11 in turn and is discharged. The air pressure is used to puncture the battery of the faulty vehicle, and then the valve of the pressure water source is opened. Water passes through the soft water pipe 5 and the water collecting cylinder in turn and is sprayed out from the main pipe 9, and the water is injected into the battery pack of the accident vehicle to extinguish the fire.

[0034] Furthermore, the water collecting cylinder includes a lower cylinder 7 and an upper cylinder 8 which is rotatably connected with the lower cylinder 7. The main cylinder 9 and the upper cylinder 8 are integrally formed. The water inlet pipe 10 and the air outlet pipe 11 are both fixed to the lower cylinder 7. The top of the upper cylinder 8 is provided with a plurality of branch pipes 12 distributed around the main cylinder 9 in an annular array. The branch pipes 12 are bent at the first bend 13 and the second bend 14 respectively. When water flows through the branch pipes 12, the recoil force formed by the water at the first bend 13 drives the branch pipes 12 and the upper cylinder 8 to rotate as a whole. The water sprayed from the plurality of branch pipes 12 can form a conical partition. The partition can effectively isolate the outside air from entering the partition, thereby accelerating the oxygen consumption in the partition, thereby improving the fire extinguishing efficiency, and because the branch pipe 12 is rotating, the recoil forces in various directions on the trolley 1 are balanced and mutually balanced, thereby preventing the trolley 1 from being easily tipped over by the recoil force from a certain direction. The branch pipe 12 and the main pipe 9 cooperate to increase the water coverage area and improve the fire extinguishing efficiency. The recoil force formed by the water at the second bend 14 is downward, which can make the trolley 1 more stable on the ground, thereby preventing the trolley 1 from tipping over due to the recoil force.

[0035] Furthermore, a material box 15 is fixed in the mounting groove 6, and the material box 15 is filled with a foaming agent. A first pipe 16 is connected to the bottom of the material box 15, and the other end of the first pipe 16 leads to the lower cylinder 7. A second pipe 17 for passing the foaming agent to the water collecting cylinder is connected to one side of the material box 15. A gate valve assembly is arranged in the first pipe 16, and a one-way valve 18 is installed in the second pipe 17. After opening the gate valve assembly, water enters the material box 15 from the first pipe 16, and the water and the foaming agent are mixed and flow into the water collecting cylinder from the second pipe 17. A large amount of foam is formed and sprayed out under the action of the water flow, thereby improving the fire extinguishing effect.

[0036] Furthermore, a pair of baffles 30 distributed up and down are provided on the circumferential outer wall of the upper cylinder 8, and an outer guide ring 29 with a U-shaped cross-section that is rotatably connected to the upper cylinder 8 is provided between the two baffles 30. The other end of the second pipe 17 leads to the outer guide ring 29. The upper cylinder 8 is provided with a plurality of circular holes 31 distributed in an annular array and corresponding to the position of the outer guide ring 29. After the water and the foaming agent are mixed, they flow into the outer guide ring 29 from the second pipe 17, and then flow into the water collecting cylinder through the circular holes 31. When the upper cylinder 8 rotates, the foaming agent and water are fully stirred through the rotating circular holes 31, so that they quickly generate foam.

[0037] Furthermore, an inner guide ring 32 with a U-shaped cross-section is fixed to the circumferential inner wall of the upper cylinder 8, the circular hole 31 is located between the outer guide ring 29 and the inner guide ring 32, the inner arc surface of the inner guide ring 32 is connected to the third pipe 33, and a cylinder 34 coaxial with the main pipe 9 is fixed to the inner wall of the top of the upper cylinder 8, and the other end of the third pipe 33 leads to the cylinder 34, water and foaming agent flow into the inner guide ring 32 through the circular hole 31, and then flow into the cylinder 34 through the third pipe 33, and then follow the water flow to be sprayed out from the main pipe 9, so that the foam is not sprayed out through the branch pipe 12, thereby avoiding affecting the barrier formed by the water of the branch pipe 12.

[0038] Furthermore, the gate valve assembly includes a valve box 19 installed on the first pipe 16, and a sealing plate 20 for blocking the first pipe 16 is arranged in the valve box 19. The top of the sealing plate 20 is detachably connected to a column 21 whose top passes through the valve box 19. A spring 22 is sleeved on the column 21, and the top of the spring 22 is fixed on the top inner wall of the valve box 19, and the bottom end of the spring 22 is fixed on the sealing plate 20. A component for intermittently lifting the column 21 is provided on the upper cylinder 8. The component for intermittently lifting the column 21 will intermittently lift the column 21 upward, and the column 21 drives the sealing plate 20 to move upward, so that water can pass through the first pipe 16 normally, and then the sealing plate 20 is pushed back and moved downward under the elastic force of the spring 22, and the first pipe 16 is sealed again, so that the foaming agent is intermittently flushed out, so that the foaming agent is used in an optimal way.

[0039] Furthermore, the component for intermittently lifting the column 21 includes a second T-block 24 fixed on the circumferential outer wall of the upper cylinder 8, and a first T-block 23 that can contact the second T-block 24 is provided on the side of the top of the column 21. When the upper cylinder 8 rotates, it drives the second T-block 24 to rotate. When the second T-block 24 contacts the first T-block 23, the second T-block 24 will push the first T-block 23 upward, thereby lifting the column 21 upward.

[0040] Furthermore, a stud 25 is provided at the bottom end of the column 21, and a threaded groove 26 that can form a threaded connection with the stud 25 is opened at the top end of the sealing plate 20. The bottom end of the column 21 is inserted into the valve box 19, and then the column 21 is rotated and the stud 25 is tightened into the threaded groove 26, so that it can be easily installed.

[0041] Furthermore, a feeding pipe is provided at the top of the material box 15 , and a cover 35 is threadedly connected to the feeding pipe. By opening the cover 35 , the foaming agent can be conveniently added to the material box 15 .

[0042] Furthermore, an impeller is provided in the water collecting cylinder, and the impeller includes a ring 27 mounted on the air outlet pipe 11 and a plurality of blades 28 distributed in a circular array on the outer wall of the ring 27. The blades 28 are fixed to the bottom end of the upper cylinder 8. When the upper cylinder 8 rotates, the impeller is driven to rotate synchronously to form a vortex, which can enhance the stirring effect on the foaming agent, thereby accelerating the foaming.
