Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically a fire extinguishing robot for new energy vehicles. Background Technology

[0002] New energy vehicles are cars that use electricity as their energy source and are powered by batteries. Because the batteries in new energy vehicles are prone to catching fire after overheating or being punctured by a collision, it is necessary to extinguish the fire promptly and quickly once a fire is discovered in a new energy vehicle.

[0003] Existing fire extinguishing devices for new energy vehicles, such as the one disclosed in CN220938841U, have the advantage of forming a water curtain with multiple sets of high-pressure mist water jets to spray onto the bottom of the burning vehicle, thus cooling and extinguishing the fire. However, when extinguishing fires on the bottom battery of new energy vehicles, it is inconvenient to adjust the length of the extinguishing process or to swing and adjust the extinguishing range, which limits its extinguishing effect. Therefore, we propose a fire extinguishing robot for new energy vehicles. Utility Model Content

[0026] The following describes some embodiments of the new energy vehicle fire extinguishing robot provided by this utility model with reference to the accompanying drawings.

[0027] Example 1:

[0028] Combination Figure 1-6As shown, the new energy vehicle fire extinguishing robot provided by this utility model includes: a robot car 100 and a lower fire extinguishing assembly 200; the robot car 100 includes an electrical box 101 and a water tank 102 fixedly installed on its top two sides respectively, and a pulse-type high-pressure water cannon 103 and a camera device 104 fixedly installed on the top and front end of the water tank 102 respectively; the lower fire extinguishing assembly 200 includes a fixed base 201 fixedly installed on the rear side of the bottom of the robot car 100, and a movable arm 2 rotatably connected to the bottom of the fixed base 201. 02. A restraint cavity 203 is provided inside the movable arm 202; an extension arm 204 is movably installed inside the restraint cavity 203; a first reduction motor 205 is fixedly installed on the front side of the bottom of the robot car 100; a connecting rod 206 is rotatably connected to the bottom of the first reduction motor 205; a movable sleeve 207 is rotatably connected to the bottom of the connecting rod 206; an electric three-way valve 208 is fixedly installed at the front of the extension arm 204; and an upper nozzle 209 and a side nozzle 210 are fixedly installed at the upper front end and both sides of the extension arm 204, respectively. A slot 211 is opened on one side of the movable arm 202. A gear 212 is movably installed on one side of the slot 211. A second reduction motor 213 is fixedly installed on the outer end of the gear 212 and is fixed to the movable arm 202. A rack 214 is fixedly installed on one side of the extension arm 204, and the rack 214 is meshed with the gear 212. Stops 215 are fixedly installed on both sides of the rear end of the extension arm 204. The electric three-way valve 208 in the extension arm 204 is also... A single connecting pipe 216 and a double connecting pipe 217 are fixedly installed, and the single connecting pipe 216 and the double connecting pipe 217 are fixedly connected to the upper nozzle 209 and the side nozzle 210, respectively. A liquid pump 218 is also fixedly installed at the front end of the water tank 102. A water pipe 219 is also fixedly connected to the liquid pump 218. The front end of the water pipe 219 is installed inside the extension arm 204 and is fixedly connected to the electric three-way valve 208. The movable sleeve 207 is movably installed at the outer end of the movable arm 202. The extension arm 204 is a vacuum structure.

[0029] Specifically, new energy vehicles are cars powered by electricity and driven by batteries. Because the batteries in new energy vehicles are prone to catching fire after overheating or being punctured in a collision, it is necessary to promptly and quickly extinguish the fire at the bottom of the battery when a fire is discovered. The movable arm 202 installed at the bottom of this robot car 100 can move the extension arm 204 inside the movable arm 202 through the gear 212 driven by the second reduction motor 213, thereby increasing the fire extinguishing length of the front upper nozzle 209 and the side nozzles 210. It can also be driven by the first reduction motor 205. The movable sleeve 207 cyclically swings the movable arm 202 and the extension arm 204, thereby increasing the fire extinguishing range of the front upper nozzle 209 and the side nozzle 210. This improves the practicality of the lower fire extinguishing structure of the robotic vehicle 100 by extending the fire extinguishing length and range of the upper nozzle 209 and the side nozzle 210. Simultaneously, the electric three-way valve 208 installed at the front of the extension arm 204 can flexibly open or close the upper nozzle 209 or the side nozzle 210 according to actual fire extinguishing needs, thus saving water and extending the fire extinguishing time. The restraint cavity 203 within the movable arm 202 mainly... The first geared motor 205 drives a connecting rod 206 to restrain the movement of the extension arm 204. This rod moves outside the extension arm 202 via a transmission sleeve 207, causing the extension arm 202 to swing along the fixed base 201. This, in turn, swings the upper nozzle 209 or side nozzle 210 at the front end of the extension arm 204. The second geared motor 213 drives a gear 212 on the extension arm 202, which, through a rack 214, extends and retracts the extension arm 204 within the extension arm 202, thereby adjusting the position of the upper nozzle 209 or side nozzle 210 at the front of the extension arm 204. The stop blocks 215 installed on both sides of the extension arm 204 are mainly used to restrain the extension arm 204 and prevent it from falling out of the restraint chamber 203. The extension arm 204 is a vacuum structure to ensure easy adjustment. The single pipe 216 and the double pipe 217 on both sides of the electric three-way valve 208 are mainly used to supply water to the upper nozzle 209 and the side nozzle 210, respectively. The liquid pump 218 at the front end of the water tank 102 is mainly used to supply water in the lower fire extinguishing process, so as to transport the water source to the electric three-way valve 208 through the water pipe 219, and extinguish the fire through the upper nozzle 209 and the side nozzle 210 connected by the electric three-way valve 208.

[0030] Working principle and usage process of this utility model:

[0031] When extinguishing a fire in a new energy vehicle, the robot car 100 is first moved to the front or rear of the vehicle. After the robot car 100 is in position, the liquid pump 218 is started to deliver extinguishing water. Once the extinguishing water is delivered, the second reduction motor 213 on the movable arm 202 is started. This, through the gear 212 driven by the second reduction motor 213, drives the extension arm 204 inside the movable arm 202 to move forward until it reaches the bottom of the fire area. This allows the water to be sprayed upwards from the front end of the extension arm 204. When the head 209 is used for fire extinguishing, the first reduction motor 205 at the bottom of the robot car 100 can also be started to drive the rotating connecting rod 206 to swing the movable arm 202 and the extension arm 204 together through the movable sleeve 207, thereby expanding the spraying range of the upper nozzle 209. After the fire is extinguished on the upper part of the upper nozzle 209, the electric three-way valve 208 can also be started to close the connecting single pipe 216 and open the connecting double pipe 217, so that the fire on the lower side of the car can be extinguished through the side nozzles 210 on both sides.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
