Description

Technical Field

[0001] This utility model relates to the field of fire-fighting robot technology, and in particular to a combined car cooling and fire-extinguishing robot. Background Technology

[0002] With the increasing popularity of new energy vehicles, more and more people are using electric vehicles in their daily lives, which brings with it the issue of fire safety. Electric vehicle batteries are prone to catching fire under high temperatures or impacts. Battery fires are complex, spread rapidly, and are difficult to extinguish. Timely cooling of the battery is crucial for controlling the fire. Since the battery packs of electric vehicles are mostly located under the vehicle body, traditional firefighting methods, which involve spraying large amounts of water onto the entire vehicle, cannot accurately cool the batteries at the bottom of the vehicle, resulting in ineffective firefighting. Furthermore, the effectiveness of traditional firefighting methods is further weakened when large vehicles or vehicles with low chassis catch fire, making it impossible to effectively control the fire. Utility Model Content

[0003] The purpose of this invention is to provide a combined car cooling and fire extinguishing robot. This robot has two fire extinguishing mechanisms, which increases the fire extinguishing range. Moreover, the two fire extinguishing mechanisms are low in height, which allows them to easily penetrate under the vehicle to precisely cool the battery and quickly and effectively control the fire.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a combined car cooling and fire extinguishing robot, comprising an active fire extinguishing mechanism and a passive fire extinguishing mechanism. The active fire extinguishing mechanism includes a housing, with a cover plate on the top of the housing, and a plurality of mounting holes evenly distributed on the cover plate. Walking mechanisms are provided on both sides of the housing. A fire extinguishing pipeline is installed inside the housing, including a water inlet pipe. One end of the water inlet pipe has a first water inlet, and the other end has a water outlet. A plurality of water inlet branch pipes are evenly connected to both sides of the water inlet pipe. The water inlet branch pipe is perpendicular to the water inlet pipe. The end of the water inlet branch pipe is connected to a vertically upward-mounted sprinkler pipe. The outlet of the sprinkler pipe is equipped with a first nozzle, which is located in the mounting hole. The driven fire extinguishing mechanism includes a fire extinguishing frame. The bottom of the fire extinguishing frame is equipped with casters. A water inlet channel is provided inside the fire extinguishing frame. Second nozzles are evenly arranged on the top of the fire extinguishing frame. A second water inlet is provided on the side of the fire extinguishing frame near the casing. The second water inlet is connected to the water inlet channel. A connecting pipe is provided between the water outlet and the second water inlet.

[0005] Optionally, the traveling mechanism may be a tracked traveling mechanism.

[0006] Optionally, the outer side of the walking mechanism is provided with an integral track guard plate.

[0007] Optionally, quick connectors are provided on the outlet and the second inlet, and the connecting pipe is connected between the outlet and the second inlet through a quick structure.

[0008] Optionally, the fire extinguishing frame is a rectangular frame, and the water inlet channel is an annular channel that matches the fire extinguishing frame.

[0009] Optionally, casters are installed at the four corners of the fire extinguishing frame.

[0010] The combined car cooling and fire extinguishing robot of this utility model has the following advantages:

[0011] (1) The combination of active fire extinguishing mechanism and passive fire extinguishing mechanism can increase the fire extinguishing range of the robot and improve the fire extinguishing capability of the robot; the active fire extinguishing mechanism can drive the passive fire extinguishing mechanism to move. Since the main body of the passive fire extinguishing mechanism is the fire extinguishing frame, it is lower in height and can enter the gap to extinguish the fire, and has a wider range of applications; when the spray water falls, it will also cool down the robot itself for protection.

[0012] (2) The tracked walking mechanism is highly adaptable to the terrain and can move and extinguish fires in most fire areas. The track guard plate can protect the walking mechanism, isolate some of the flames from the walking mechanism, and prevent the fire extinguishing robot from being unable to move and losing its fire extinguishing ability due to the failure of the walking mechanism.

[0013] (3) Quick couplings can save installation time for connecting pipes and improve efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-5As shown, a combined car cooling and fire extinguishing robot includes an active fire extinguishing mechanism 1 and a passive fire extinguishing mechanism 2. The active fire extinguishing mechanism 1 includes a chassis 3, with walking mechanisms 4 on both sides of the chassis 3. The walking mechanisms 4 are tracked, which have strong adaptability to terrain. The outer side of the walking mechanisms 4 is equipped with an integral track guard plate 5 to provide high-temperature fire protection for the tracks, preventing high-temperature flames from scorching the tracks and avoiding malfunctions of the walking mechanisms 4. A partition is horizontally arranged inside the chassis 3, dividing the chassis 3 into an upper space and a lower space. The lower space is equipped with power components such as batteries and controllers. The chassis 3 is equipped with start / stop buttons 6, charging ports, data transmission antennas 7, power display screens 8, and emergency stop buttons 9, etc. The robot's movement can be controlled by a remote control. Fire extinguishing pipe 10 is installed in the upper space inside the chassis 3. The fire extinguishing pipe 10 includes a water inlet pipe 11. One end of the water inlet pipe 11 is provided with a first water inlet 12, and the other end of the water inlet pipe 11 is provided with a water outlet 13. Several water inlet branch pipes 14 are evenly connected to both sides of the water inlet pipe 11. The water inlet branch pipes 14 are perpendicular to the water inlet pipe 11. The end of the water inlet branch pipes 14 is connected to a vertically upward-mounted sprinkler pipe 15. A first nozzle 16 is installed at the outlet of the sprinkler pipe 15. A cover plate 17 is provided on the top of the chassis 3. Several mounting holes are evenly opened on the cover plate 17. The first nozzle 16 is located in the mounting hole.

[0021] The driven fire extinguishing mechanism 2 includes a fire extinguishing frame 18, which is a rectangular frame with an annular water inlet channel inside. Second nozzles 19 are evenly distributed on the top of the fire extinguishing frame 18 and are connected to the water inlet channel. A second water inlet 20 is located on the side of the fire extinguishing frame 18 near the housing 3. Quick connectors 21 are provided on the outlet 13 and the second water inlet 20. A connecting pipe 22 connects the outlet 13 and the second water inlet 20 via the quick connectors 21. The quick connectors 21 save installation time on the connecting pipe 22 and improve the connection efficiency between the active fire extinguishing mechanism 1 and the driven fire extinguishing mechanism 2. Casters 23 are installed at the bottom of the fire extinguishing frame 18 at its four corners. Two connecting rods 24 are hinged between the fire extinguishing frame 18 and the housing 3, symmetrically installed on both sides of the connecting pipe 22, facilitating stable movement of the fire extinguishing frame 1 by the active fire extinguishing mechanism 1.

[0022] When using a robot for firefighting, first transport the robot to the work site, connect the connecting pipe 22 between the outlet 13 and the second inlet 20, connect the fire hose to the first inlet 12, and then remotely operate the active fire extinguishing mechanism 1 to drive the driven fire extinguishing mechanism 2 into the bottom of the burning vehicle. The driven fire extinguishing mechanism 2 can enter locations that the active fire extinguishing mechanism 1 cannot reach. When it moves to the location of the battery pack, it activates the fire water to precisely cool and extinguish the battery. The fire extinguishing effect is good and fast, and the spray water also cools and protects the robot itself, improving the robot's continuous operation capability. Solenoid valves can also be installed at the first nozzle 16 and the second nozzle 19, which allows for active control of the fire water spray, making the robot's firefighting operation more flexible. In addition, the first inlet 12 can also be connected to other fire extinguishing equipment to use foam, gas, or other fire extinguishing media for firefighting operations.
