Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a water supply device for a fire-fighting robot. Background Technology

[0002] The dedicated water supply system for firefighting robots is a core support system that ensures the robots can continuously and efficiently extinguish fires. This equipment typically adopts a modular design, allowing it to quickly dock with the robot body or be integrated into its chassis. The water supply system mainly consists of a high-pressure water pump, high-temperature and high-pressure resistant pipelines, intelligent control valves, and filtration devices.

[0003] The water pump provides a stable and powerful water flow, ensuring range and penetration. The intelligent control module can adjust the water flow and spray mode (such as direct current or mist) in real time according to the fire situation, achieving water conservation optimization while extinguishing fires efficiently. The equipment supports connection to external fire hydrants or has its own water tank and features a quick water replenishment interface to ensure the continuity of firefighting operations. With its high reliability, strong adaptability, and intelligent control capabilities, this water supply system has become a key guarantee for the firefighting robot to perform its tasks, significantly improving the robot's independent operation and firefighting efficiency.

[0004] The water supply system relies on flexible water pipes, and bends in the pipes can cause water supply obstruction. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, the present invention provides a water supply device for a fire extinguishing robot, which can ensure smooth water supply.

[0006] The technical solution adopted in this invention is:

[0007] The water supply equipment for the fire-fighting robot includes a pressure system, a pipe system, a water supply pipe, and a water cannon system. The pressure system has an outlet pipe. The pipe system includes a pipe support rod, a pipe rod telescopic device, and a hydraulic traction device. The pipe rod telescopic device is installed on the outlet pipe. The hydraulic traction device includes a hydraulic opening component, an opening return spring, an opening degree maintaining rope, and a limiting slider. The limiting slider is slidably installed inside the pipe support rod. The hydraulic opening component is installed on the side of the pipe support rod away from the pressure system. The length of the opening return spring in its free state is shorter than the opening degree maintaining rope. The hydraulic opening assembly has an opening and closing end. One end of the opening degree maintaining rope is installed on the limiting slider, and the other end of the opening degree maintaining rope is installed on the opening and closing end of the hydraulic opening assembly through the opening degree control rope. Both ends of the opening reset spring are installed on the opening degree control rope and the limiting slider. A limiting block is provided inside the pipe support rod. The limiting slider presses against the side of the limiting block near the pressure system. The limiting block is provided with a neodymium iron boron permanent magnet that attracts the limiting slider. The pipe extension device is connected to the limiting slider in a transmission connection. The water outlet pipe of the pressure system is connected to the water cannon system through the water supply pipe.

[0008] Preferably, the pressure system includes a drive engine, a transmission device, and a water pump, wherein the drive engine is connected to the water pump via the transmission device, and the water pump has an outlet pipe.

[0009] Preferably, the water cannon system includes a rotating device and an tilt adjustment device. The rotating device is connected to the water supply pipe, and the tilt adjustment device is rotatably mounted on the rotating device.

[0010] Preferably, the pipe support rod has a rounded head on the side near the water cannon system.

[0011] Preferably, the pipe extension device includes a traction rope winding reel, a traction rope winding motor, and a reset traction rope. The traction rope winding reel is rotatably installed inside the water outlet pipe, the traction rope winding motor is installed on the water outlet pipe, the reset traction rope is wound around the traction rope winding reel, and the reset traction rope is installed on the limit slider.

[0012] Preferably, the hydraulic opening assembly includes an elastic plate and a water-collecting cover. The elastic plate is installed on the side wall of the pipe support rod, and each elastic plate is installed on the water-collecting cover. The end of the elastic plate forms an opening and closing end.

[0013] Preferably, the open return spring is a rubber rope.

[0014] Preferably, the distance between the limiting slider and the inner wall of the through pipe support rod is 0.5 mm to 1 mm.

[0015] The beneficial effects of this invention are:

[0016] The pressure system has an outlet pipe to achieve pressurized water supply. The pipe connection system includes a pipe connection support rod, a pipe connection rod telescopic device, and a hydraulic traction device. The hydraulic traction device is used to drive the pipe connection support rod to move inside the water supply pipe under the action of water flow. The pipe connection rod telescopic device realizes the reset of the pipe connection support rod. The pipe connection rod telescopic device is installed on the outlet pipe and is used to pull the pipe connection support rod to move, thus realizing the reset of the pipe connection support rod.

[0017] The hydraulic traction device includes a hydraulic opening component, an opening return spring, an opening degree holding rope, and a limiting slider. The limiting slider is slidably installed inside the pipe support rod. The hydraulic opening component is installed on the side of the pipe support rod away from the pressure system. The length of the opening return spring in its free state is shorter than that of the opening degree holding rope. The hydraulic opening component has an opening and closing end, and after water is introduced...

[0018] The hydraulically opening assembly unfolds, causing the pipe support rod to move inside the water supply pipe, ensuring unobstructed water flow. One end of the opening maintaining rope is mounted on the limit slider, and the other end is mounted on the opening / closing end of the hydraulically opening assembly via the opening control rope. The two ends of the opening return spring are mounted on the opening control rope and the limit slider. A limit block is located inside the pipe support rod, with the limit slider pressing against the side of the limit block closest to the pressure system. The limit block has neodymium iron boron permanent magnets that attract the limit slider. The combined use of the neodymium iron boron permanent magnets on the limit block and the opening return spring ensures that during the unfolding of the hydraulically opening assembly… The tension of the pipe extension device on the limiting slider does not affect the deployment of the hydraulic opening component. However, when the pipe support rod is retracted, since the water pipe is now clear, the water pressure is directly transmitted to the hydraulic opening component. When the pipe extension device retracts at this time, it is resisted by the hydraulic opening component. The pipe extension device pulls the limiting slider to overcome the attraction of the neodymium iron boron magnet, and the hydraulic opening component is retracted accordingly. The pipe extension device and the limiting slider are connected by a transmission. When the pipe extension device drives the limiting slider to move, the hydraulic opening component retracts, which facilitates the reset of the pipe support rod. The outlet pipe of the pressure system is connected to the water cannon system through the water supply pipe. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figure 1 — Figure 7 As shown, this embodiment provides a water supply device for a fire extinguishing robot, including a pressure system 1, a pipe system 2, a water supply pipe 3, and a water cannon system 4. The pressure system 1 has a water outlet pipe 15 to achieve pressurized water supply. The pipe system 2 includes a pipe support rod 21, a pipe rod telescopic device 22, and a hydraulic traction device 23. The hydraulic traction device 23 is used to drive the pipe support rod 21 to move within the water supply pipe 3 under the action of water flow. The pipe rod telescopic device 22 resets the pipe support rod 21. The pipe rod telescopic device 22 is installed on the water outlet pipe 15 and is used to pull the pipe support rod 21 to move, thereby resetting the pipe support rod 21.

[0033] The hydraulic traction device 23 includes a hydraulic opening assembly 231, an opening return spring 232, an opening degree maintaining rope 233, and a limiting slider 234. The limiting slider 234 is slidably installed inside the pipe support rod 21. The hydraulic opening assembly 231 is installed on the side of the pipe support rod 21 away from the pressure system 1. The length of the opening return spring 232 in its free state is shorter than that of the opening degree maintaining rope 233. The hydraulic opening assembly 231 has an opening and closing end. Please note... Figure 7 , Figure 7 In the state where the pipe rod telescopic device 22 pulls the opening holding rope 233, so that the opening holding rope 233 maintains tension, and the hydraulic opening component 231 is as follows: Figure 7 As indicated, when the pipe is closed, the water flow decreases due to bends, and the pipe extension device 22 gradually loosens. Figure 5 In this state, the opening holding rope 233 is released, causing the hydraulic opening component 231 to gradually open. As the hydraulic opening component 231 gradually opens, the opening return spring 232 is gradually pulled open until it reaches the desired state. Figure 6 When the opening return spring 232 is stretched to its longest state, the hydraulic opening component 231 reaches its maximum opening. The opening holding rope 233 is taut, maintaining the hydraulic opening component 231 in its unfolded state. The hydraulic opening component 231 drives the pipe support rod 21 to push the bent water pipe, releasing the water pipe from the bend. During retraction, the pipe extension device 22 pulls, causing the hydraulic opening component 231 and the pipe support rod 21 to retract.

[0034] Specifically, after water is supplied, the hydraulic opening assembly 231 unfolds, causing the pipe support rod 21 to move inside the water supply pipe 3, ensuring the water supply pipe 3 remains unobstructed. One end of the opening degree holding rope 233 is installed on the limiting slider 234, and the other end of the opening degree holding rope 233 is installed on the opening and closing end of the hydraulic opening assembly 231 via the opening degree control rope 235. Both ends of the opening reset spring 232 are installed on the opening degree control rope 235 and the limiting slider 234. A limiting block 211 is provided inside the pipe support rod 21. The limiting slider 234 presses against the side of the limiting block 211 closest to the pressure system 1. The limiting block 211 is provided with neodymium iron boron permanent magnets that attract the limiting slider 234. The combined use of the neodymium iron boron permanent magnets on the limiting block 211 and the opening reset spring 232 ensures that the hydraulic opening assembly... During the unfolding of component 231, the pulling force of the pipe extension device 22 on the limiting slider 234 will not affect the unfolding of the hydraulic opening component 231. However, when the pipe support rod 21 is retracted, since the water pipe is already cleared, the water pressure is directly transmitted to the hydraulic opening component 231. When the pipe extension device 22 is retracted, it is resisted by the hydraulic opening component 231. The pipe extension device 22 pulls the limiting slider 234 to overcome the attraction of the neodymium iron boron magnet, and the hydraulic opening component 231 is retracted accordingly. The pipe extension device 22 is connected to the limiting slider 234 through a transmission. When the pipe extension device 22 drives the limiting slider 234 to move, the hydraulic opening component 231 retracts, which facilitates the reset of the pipe support rod 21. The outlet pipe 15 of the pressure system 1 is connected to the water cannon system 4 through the water supply pipe 3.

[0035] Specifically, the pressure system 1 includes a drive engine 11, a transmission device 12, and a water pump 13. The drive engine 11 is connected to the water pump 13 via the transmission device 12. The water pump 13 has an outlet pipe 15. The drive engine 11 drives the water pump 13 to pressurize the water.

[0036] Specifically, the water cannon system 4 includes a rotating device 41 and an tilt adjustment device 42. The rotating device 41 is connected to the water supply pipe 3. The tilt adjustment device 42 is rotatably mounted on the rotating device 41 to change the direction of water flow. The rotating device 41 and the tilt adjustment device 42 are existing technologies and will not be described in detail here.

[0037] Specifically, the pipe support rod 21 has a round head on the side near the water cannon system 4 to facilitate the movement of the pipe support rod 21.

[0038] Specifically, the pipe extension device 22 includes a traction rope winding reel, a traction rope winding motor 221, and a reset traction rope 222. The traction rope winding reel is rotatably installed inside the water outlet pipe 15. The traction rope winding motor 221 is installed on the water outlet pipe 15. The reset traction rope 222 is wound around the traction rope winding reel and is installed on the limit slider 234. The traction rope winding motor 221 drives the traction rope winding reel to wind up, and the reset traction rope 222 realizes the reset of the pipe support rod 21.

[0039] Specifically, the hydraulic opening component 231 includes an elastic plate 2311 and a water-collecting cover 2312. The elastic plate 2311 is installed on the side wall of the pipe support rod 21, and each elastic plate 2311 is installed on the water-collecting cover 2312 by rivets. The ends of the elastic plates 2311 form opening and closing ends. The water-collecting cover 2312 unfolds under the action of water flow, causing the elastic plate 2311 to open. When the pipe support rod telescopic device 22 is retracted, the opening control rope 235 drives the elastic plate 2311 to retract, thereby retracting the water-collecting cover 2312. In order to avoid the elastic plate 2311 getting stuck on the inner wall of the water pipe when the pipe support rod 21 is retracted, when the elastic plate 2311 unfolds the water-collecting cover 2312, the diameter of the water-collecting cover 2312 is 0.9 times the diameter of the hose. This allows the water-collecting cover 2312 to obtain sufficient traction force while avoiding getting stuck.

[0040] Specifically, the open return spring 232 is a rubber rope that enables the water cover 2312 to retract when the water flow is not through.

[0041] Specifically, the distance between the limiting slider 234 and the inner wall of the through pipe support rod 21 is 0.5 mm to 1 mm to avoid jamming.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention.
