Description

Technical Field

[0001] This invention relates to the field of fire hose trailer transportation and detachment technology, specifically a remote-controlled fire extinguishing robot hose detachment trailer. Background Technology

[0002] Fire hose trailers are mainly used for transporting fire hoses by fire-fighting robots. Fire-fighting robots are used by firefighters in fire rescue operations involving explosions, collapses, and other hazards to improve rescue safety and reduce casualties. Therefore, fire-fighting robots typically require a safe distance of tens to hundreds of meters, which places high demands on the rapid and effective deployment of fire hoses.

[0003] Fire hoses are typically 20 meters long per reel. When firefighters cannot access the fire scene, fire-fighting robots require long hose lines, resulting in numerous hose connections. Dragging these connections on the ground can damage or detach them, preventing the robot from discharging water. Hose trailers solve most hose laying problems by folding several hoses and placing them in the trailer. One end connects to the robot, and the other end connects to the fire truck's outlet. The trailer is connected to the robot, and as the robot moves the trailer forward, the hoses fall off.

[0004] However, the hose trailer still has the following problems: when the fire truck supplies water to the robot after it arrives at the scene, the hose trailer hanging behind the robot greatly affects the normal water output of the hose; the robot's movement and relocation after it outputs water are restricted by the trailer; and the robot is obstructed by the trailer when it retreats.

[0005] Therefore, a remote-controlled fire extinguishing robot hose separation trailer is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a remote-controlled fire extinguishing robot hose separation trailer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a remote-controlled fire extinguishing robot hose separation trailer, comprising a base plate, wherein side plates are rotatably mounted on the front and rear ends of the upper side of the base plate via symmetrical hinges, a left baffle is rotatably mounted on the left end of the two side plates on the upper side of the base plate via a pivot pin, and a right baffle is rotatably mounted on the right end of the two side plates on the upper side of the base plate via a pivot pin, a first de-energized electromagnet is fixed on the front and rear sides of the left and right baffles, the left and right baffles are adsorbed and connected to the inner wall of the side plates via the first de-energized electromagnets, a first fixing ring is fixed on the lower right side of the left baffle, a second fixing ring is fixed on the left end of the upper side of the base plate, a connecting rope is fixed between the first and second fixing rings, a limit rope is fixed on the upper end of the two side plates on the side closest to each other, and a second de-energized electromagnet is fixed on the end of the two limit ropes on the side closest to each other;

[0008] A water hose is stacked on the upper end of the base plate. The left end of the water hose is located on the upper end of the left baffle, and the right end of the water hose is located on the upper end of the right baffle. A connecting pipe is fixed to the right end of the water hose.

[0009] A connecting frame is provided on the right side of the base plate, a connecting chain is fixed on the right side of the connecting frame, and a hook is fixed on the right end of the connecting chain;

[0010] Symmetrical brushless motor drive wheels are provided on the right side of the lower side of the base plate, and symmetrical follower wheels are fixed on the left side of the lower side of the base plate. A chassis is fixed on the lower side of the base plate, a battery is fixed inside the chassis, and a monitoring camera is fixed on the lower side wall of the chassis.

[0011] Both side panels have extension plates mounted on their left sides via symmetrical hinges, and a common insertion mechanism is provided between the upper side of the two extension plates and the upper side of the side panels.

[0012] Preferably, the side walls of the two side plates, the left baffle and the right baffle are all provided with protective iron mesh, and the side plates, the left baffle and the right baffle are all welded from iron pipes.

[0013] Preferably, a first spring is fixed to both the front and rear sides of the right baffle, and the opposite ends of the two first springs are in contact with the side of the side plate that is close to each other.

[0014] Preferably, a support block is fixed to the upper right end of the base plate, and a second spring is fixed to the right side of the support block, with the right end of the second spring contacting the left side of the right baffle.

[0015] Preferably, the first de-energized electromagnet and the second de-energized electromagnet are electrically connected to the power supply.

[0016] Preferably, a storage plate is provided on the upper side of the base plate at both the front and rear ends of the water hose. The storage plate has a storage cavity inside. A rotating rod is rotatably installed inside the storage cavity via a damping bearing. The right end of the rotating rod extends to the right end of the storage plate and is fixed with a handle. A winding roller is fixed to the rod wall. A sunshade layer is wound around the outside of the winding roller. An adsorption magnet is fixed to the upper end of the sunshade layer.

[0017] Preferably, the insertion mechanism includes a fixed plate, which is fixedly connected to the upper left end of the side plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1) After the trailer arrives at the scene with the fire-fighting robot, the water hose is laid out by the trailer. By controlling the electrical control electromagnet between the side panels of the trailer and the electrical control electromagnet connecting the front end of the trailer to the fire-fighting vehicle, the trailer can be quickly separated from the fire-fighting robot, which will not cause the water hose to be folded and piled up, thus avoiding affecting the normal water output of the water hose.

[0020] 2) Ensure that after the trailer is separated from the fire-fighting robot, when the fire-fighting robot needs to change the position of the water spray and the direction of the trolley, the trailer will not affect the operation of the fire-fighting robot and will not restrict the range of movement of the fire-fighting robot.

[0021] 3) When the fire-fighting robot needs to retreat after completing its work, it effectively avoids the trailer being attached to the rear end of the fire-fighting robot, thus preventing obstruction of retreat and ensuring that the fire-fighting robot can retreat normally.

Therefore, they should not be construed as limitations on this invention.

[0030] Example:

[0031] Please see Figure 1-5 The present invention provides a technical solution:

[0032] A remote-controlled fire extinguishing robot hose separation trailer includes a base plate 1. Side plates 2 are rotatably mounted on the front and rear ends of the upper side of the base plate 1 via symmetrical hinges. A left baffle 3 is rotatably mounted on the left end of the two side plates 2 on the upper side of the base plate 1 via a pivot pin. A right baffle 4 is rotatably mounted on the right end of the two side plates 2 on the upper side of the base plate 1 via a pivot pin. A first de-energized electromagnet 5 is fixed on the front and rear sides of the left baffle 3 and the right baffle 4. The left baffle 3 and the right baffle 4 are both connected to the inner wall of the side plates 2 by adsorption through the first de-energized electromagnet 5. A first fixing ring 6 is fixed on the lower right side of the left baffle 3. A second fixing ring 7 is fixed on the left end of the upper side of the base plate 1. A connecting rope 8 is fixed between the first fixing ring 6 and the second fixing ring 7. A limit rope 9 is fixed on the upper end of the two side plates 2 that are close to each other. A second de-energized electromagnet 10 is fixed on the end of the two limit ropes 9 that are close to each other.

[0033] Water is stacked on the upper end of the base plate 1. The right end of the connecting pipe 12 is connected to the water inlet of the fire robot and fixed with a strap 11. The left end of the water hose 11 is located on the upper end of the left baffle 3, and the right end of the water hose 11 is located on the upper end of the right baffle 4. The right end of the water hose 11 is fixed with a connecting pipe 12.

[0034] A connecting frame 13 is provided on the right side of the base plate 1. A connecting chain 14 is fixed on the right side of the connecting frame 13. A hook 15 is fixed on the right end of the connecting chain 14. The hook 15 is hung on the rear end of the fire truck. When the fire truck arrives at the scene, the hook position is a de-energized electromagnet. The firefighters control the electromagnet to de-energize, thereby separating the hook 15 from the fire truck.

[0035] Symmetrical brushless motor drive wheels 16 are provided on the right side of the lower side of the base plate 1. The two brushless motor drive wheels 16 are controlled separately. When both are controlled at the same time, the vehicle can only travel in a straight line. When turning is required, only one of the brushless motor drive wheels 16 needs to be controlled. A housing 18 is fixed on the lower side of the base plate 1. A battery 19 is fixed inside the housing 18. The battery is a 24V lithium battery with a capacity of 5000mA, which continuously provides power. A monitoring camera 20 is fixed on the lower side wall of the housing 18. The monitoring camera 20 can capture images of the surrounding environment to facilitate changing the direction of travel of the trailer. Symmetrical follower wheels 17 are fixed on the left side of the lower side of the base plate 1. A housing 18 is fixed on the lower side of the base plate 1. A battery 19 is fixed inside the housing 18. A monitoring camera 20 is fixed on the lower side wall of the housing 18.

[0036] Both side plates 2 have extension plates 31 mounted on their left sides via symmetrical hinges. The upper sides of the two extension plates 31 and the upper sides of the side plates 2 are connected by a common insertion mechanism.

[0037] The trailer is composed of a base plate 1, two side plates 2, a left baffle 3, a right baffle 4, a brushless motor drive wheel 16, and a follower wheel 17. The trailer dimensions are 1.2 meters long, 0.8 meters wide, 0.48 meters high, and the tire height is 0.33 meters.

[0038] The side walls of the two side plates 2, the left baffle 3 and the right baffle 4 are all equipped with protective iron mesh 21. The side plates 2, the left baffle 3 and the right baffle 4 are all welded with iron pipes. By using protective iron mesh 21, fire hoses can be fully loaded and the weight of the fire hoses can be reduced. In addition, the processing material of the side plates 2, the left baffle 3 and the right baffle 4 is iron, so that they can be used in conjunction with the first de-energized electromagnet 5 and the second de-energized electromagnet 10.

[0039] The front and rear sides of the right baffle 4 are both fixed with first springs 22. The opposite ends of the two first springs 22 are in contact with the side of the side plate 2 that is close to each other. The first springs 22 can ensure that when the second de-energized electromagnet 10 is de-energized, the two side plates 2 will flip to both ends under the elastic force of the first springs 22.

[0040] A support block 23 is fixed to the upper right end of the base plate 1. A second spring 24 is fixed to the right side of the support block 23. The right end of the second spring 24 contacts the left side of the right baffle 4. The second spring 24 can ensure that the right baffle 4 flips to the right after it separates from the two side plates 2.

[0041] The first power-off type electromagnet 5, the second power-off type electromagnet 10, and the monitoring camera 20 are all electrically connected to the power supply.

[0042] A storage plate 25 is provided on the upper side of the base plate 1 at both the front and rear ends of the water hose 11. The storage plate 25 has a storage cavity inside. A rotating rod 26 is rotatably installed inside the storage cavity via a damping bearing. The right end of the rotating rod 26 extends to the right end of the storage plate 25 and is fixed with a handle 27. A winding roller 28 is fixed to the wall of the rotating rod 26. A sunshade layer 29 is wound around the outside of the winding roller 28. An adsorption magnet 30 is fixed to the upper end of the sunshade layer 29. When the trailer is not in use, the sunshade layer 29 can be pulled out to protect the upper end of the water hose 11, thereby preventing the water hose 11 from being directly exposed to sunlight for a long time and thus extending the service life of the water hose 11.

[0043] The insertion mechanism includes a fixed plate 32, which is fixedly connected to the upper left end of the side plate 2. The fixed plate 32 has a cavity inside, and a limit block 33 is slidably arranged inside the cavity. A pull rod 34 is fixed to the right side of the limit block 33 and is slidably connected to the right side of the fixed plate 32. A third spring 35 is sleeved on the outside of the pull rod 34. The left end of the third spring 35 is fixedly connected to the right side of the limit block 33, and the right end of the third spring 35 is fixedly connected to the right end of the inner wall of the cavity. An insertion plate 36 is fixed to the left side of the limit block 33, and an insertion block 37 is fixed to the upper right end of the extension plate 31. The left end of the insertion plate 36 is inserted into the insertion block 37.

[0044] The trailer includes a control unit, which is a handheld controller held by firefighters.

[0045] It also includes a signal receiving feedback module and a control module. The signal receiving feedback module is used to receive signals sent by the control terminal and transmit the received information to the control module. The control module controls the first de-energized electromagnet 5, the second de-energized electromagnet 10, the monitoring camera 20 and the two brushless motor drive wheels 16 to start and stop their operation, and at the same time transmits the operation information to the control terminal through the signal receiving feedback module.

[0046] Working principle:

[0047] Before use, first neatly fold the water hose and place it on the top of the base plate 1. Activate the first de-energized electromagnet 5 and the second de-energized electromagnet 10. At this time, both side plates 2, the left baffle 3, and the right baffle 4 are all in a vertical position. During the transportation of the water hose, deactivate the first de-energized electromagnet 5 on the front and rear sides of the left baffle 3. Under the limiting action of the connecting rope 8, the left baffle 3 will shift and rotate 20 degrees to the left. As the trailer moves with the fire-fighting robot, the water hose will be neatly laid flat on the ground until the fire-fighting robot reaches the corresponding position. At this time, deactivate the right baffle. The first de-energized electromagnet 5, the second de-energized electromagnet 10 on the side wall of plate 4, and the de-energized electromagnet used to connect the hook 15 on the left end of the fire truck (this part is on the fire truck and is not shown in this application). The right baffle 4 rotates to the right under the elastic force of the second spring 24. The two side plates 2 rotate in opposite directions simultaneously under the action of the first spring 22. The connecting chain 14 separates from the side wall of the fire robot. After the fire robot is freed from restraint, it moves to the corresponding position. The fire is extinguished by the firefighters controlling the fire robot.

[0048] At this point, the water hoses have been completely laid on the road surface. Firefighters control the trailer by controlling its two brushless motor drive wheels 16. These two brushless motor drive wheels 16 are controlled independently. Starting them simultaneously will cause the trailer to go straight, while starting one of them will cause the trailer to turn, thus moving the trailer to its initial position.
