Description

Technical Field

[0001] This utility model relates to the field of fire-fighting robot technology, specifically a clearing component at the front end of a fire-fighting robot. Background Technology

[0002] Firefighting robots are a type of special robot primarily used for firefighting and rescue operations. Through advanced technology and powerful functions, they greatly improve the efficiency and safety of firefighting and rescue efforts. Firefighting robots can conduct reconnaissance, detection, and search and rescue operations at dangerous disaster sites such as those involving toxic substances, oxygen deficiency, or dense smoke.

[0003] In actual use, existing firefighting robots face challenges due to the unpredictable nature of accident scene environments during fires. These challenges can obstruct the robots' routes, forcing them to take detours or even preventing them from reaching their designated locations. Furthermore, obstacles can cause the robots to tip over. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a clearing component for the front end of a fire-fighting robot, comprising a robot body, tracked wheels for travel on both sides of the robot body, a mounting base fixedly mounted on the top side of the robot body, a bracket fixedly mounted on the top side of the mounting base, a water spray nozzle rotatably connected to the top of the bracket, a mounting frame fixedly mounted on one side of the front of the robot body, and a clearing component for clearing obstacles in front of the mounting frame at its end;

[0005] The obstacle clearing component includes a slide rail fixedly installed at the end of the mounting frame. A reciprocating component that can move back and forth is provided on the top side of the slide rail. A transmission component for driving the reciprocating component to move back and forth relative to each other is provided inside the slide rail. A rotating plate is rotatably connected to the reciprocating component. A cleaning plate is fixedly installed on the bottom side of the rotating plate.

[0006] The reciprocating component includes a sleeve plate that is slidably sleeved on the outside of the slide rail. A rotating column is rotatably connected to the top side of the sleeve plate, and the rotating plate is rotatably connected to the top side of the sleeve plate through the rotating column. A support plate is fixedly installed on the top side of the sleeve plate, and an electric push rod is rotatably connected to the end of the support plate. The telescopic end of the electric push rod is rotatably connected to the end of the rotating plate.

[0007] The transmission component includes a bidirectional screw rotatably connected inside the slide rail. Reciprocating sliders are slidably connected inside both sides of the slide rail, and the bidirectional screw is screwed into the center of the reciprocating slider. The sleeve is fixedly installed on the top of the reciprocating slider.

[0008] As an optimization, the ends of the cleaning plates on both sides are joined together at an angle, and several ball bearings are hinged to the bottom side of the cleaning plates.

[0009] As an optimization, the sleeve plate is U-shaped and the support plate is L-shaped at right angles.

[0010] As an optimization, a fixed base is fixedly installed on the outer side of the end of the slide rail, a servo motor is fixedly installed inside the fixed base, a drive wheel is fixedly installed on one end of the output shaft of the servo motor, a driven wheel is fixedly installed on the end of the bidirectional screw near the servo motor, and a transmission belt is driven and sleeved on the outer side of the drive wheel and the driven wheel.

[0011] The beneficial effects of this utility model are:

[0012] The obstacle-clearing component at the front of the firefighting robot uses an angled clearing plate to push obstacles to both sides. Activating the electric push rod drives the rotating plate to rotate around the rotating column, causing the clearing plates on both sides to rotate to a parallel state. Then, through internal transmission components, the sleeve plates on both sides slide relatively away, thus moving the parallel clearing plates on both sides relatively away, thereby pushing the obstacles to both sides of the robot, facilitating the robot's continued movement.

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 A clearing component at the front end of a fire-fighting robot includes a robot body 1, with tracked wheels 2 on both sides of the robot body 1 for travel, a mounting base 3 fixedly mounted on the top side of the robot body 1, a bracket 4 fixedly mounted on the top side of the mounting base 3, a water spray tube 5 rotatably connected to the top of the bracket 4, a mounting frame 6 fixedly mounted on one side of the front of the robot body 1, and a clearing component 7 for clearing obstacles in front of the mounting frame 6 is provided at the end of the mounting frame 6.

[0021] Please see Figure 2-3 The obstacle clearing component 7 includes a slide rail 8 fixedly installed at the end of the mounting frame 6. A reciprocating component that can move back and forth is provided on the top side of the slide rail 8. A transmission component is provided inside the slide rail 8 to drive the reciprocating component to move back and forth relative to each other. A rotating plate 9 is rotatably connected to the reciprocating component. A cleaning plate 10 is fixedly installed on the bottom side of the rotating plate 9. The ends of the two cleaning plates 10 are joined together at an angle. Several ball bearings 11 are hinged on the bottom side of the cleaning plate 10. By driving the reciprocating component to slide relative to each other through the transmission component, the servo motors 19 on both sides can be driven to move away from each other. Therefore, the obstacles blocking the front will be pushed aside to both sides, thereby completing the obstacle clearing function and facilitating the passage of the fire-fighting robot.

[0022] Please see Figure 2-3The reciprocating component includes a sleeve plate 12 that is slidably sleeved on the outside of the slide rail 8. The sleeve plate 12 is U-shaped. A rotating column 13 is rotatably connected to the top side of the sleeve plate 12, and a rotating plate 9 is rotatably connected to the top side of the sleeve plate 12 through the rotating column 13. A support plate 14 is fixedly installed on the top side of the sleeve plate 12. The support plate 14 is L-shaped with a right angle. An electric push rod 15 is rotatably connected to the end of the support plate 14, and the telescopic end of the electric push rod 15 is rotatably connected to the end of the rotating plate 9. The electric push rod 15 pushes and pulls the rotating plate 9, which in turn drives the rotating plate 9 to rotate around the rotating column 13 as an axis. Therefore, the cleaning plates 10 on both sides rotate to a parallel state, thereby clearing the obstacles to both sides.

[0023] Please see Figure 4 The transmission component includes a bidirectional screw 16 rotatably connected inside the slide rail 8. Reciprocating sliders 17 are slidably connected inside both sides of the slide rail 8, and the bidirectional screw 16 is screwed into the center of the reciprocating slider 17. The sleeve 12 is fixedly installed on the top of the reciprocating slider 17. By rotating the bidirectional screw 16 inside the reciprocating slider 17, the reciprocating sliders 17 on both sides can be driven to move closer to or away from the moving tube, thereby pushing the obstacles on both sides to the sides of the robot, making it easier for the robot to move forward.

[0024] Please see Figure 4 A fixed base 18 is fixedly installed on the outer side of the end of the slide rail 8. A servo motor 19 is fixedly installed inside the fixed base 18. A drive wheel 20 is fixedly installed on one end of the output shaft of the servo motor 19. A driven wheel 21 is fixedly installed on the end of the bidirectional screw 16 near the servo motor 19. A transmission belt 22 is provided on the outer side of the drive wheel 20 and the driven wheel 21. By starting the fixed base 18, the drive wheel 20 can be driven to rotate, which in turn will drive the driven wheel 21 to rotate through the transmission belt 22, thereby driving the bidirectional screw 16 to rotate inside the reciprocating slider 17.

[0025] In use, the fire-fighting robot is first driven forward by the track wheels 2. When it encounters an obstacle, the cleaning plates 10, which are joined together at an angle, can push the obstacle to both sides. As the obstacle gathers on both sides, it will slow down the movement speed of the fire-fighting robot. At this time, the electric push rod 15 can be activated, which will push the rotating plate 9, so that the rotating plate 9 rotates around the rotating column 13 as the axis, thus driving the cleaning plates 10 on both sides to rotate to a parallel state.

[0026] At the same time, the servo motor 19 is restarted to drive the drive wheel 20 to rotate, which in turn drives the driven wheel 21 to rotate through the transmission belt 22. This in turn drives the bidirectional screw 16 to rotate inside the reciprocating slider 17, causing the reciprocating sliders 17 on both sides to slide away from each other. This causes the sleeve plates 12 on both sides to slide away from each other along the top side of the slide rail 8. As a result, the parallel cleaning plates 10 on both sides are moved away from each other, thus pushing the obstacles to both sides of the robot, making it easier for the robot to continue moving.

[0027] In summary, the obstacle-clearing component at the front of the fire-fighting robot, through the angled clearing plate 10 at the front of the robot, will push obstacles to both sides. Activating the electric push rod 15 will push the rotating plate 9 to rotate around the rotating column 13, causing the clearing plates 10 on both sides to rotate to a parallel state. Then, through the internal transmission components, the sleeve plates 12 on both sides will slide relatively away, thus causing the parallel clearing plates 10 on both sides to move relatively away, thereby pushing the obstacles to both sides of the robot, facilitating the robot's continued movement.
