[0017] Please refer to the appendix carefully. Figure 1-4 A crawler suitable for cleaning water supply and drainage pipes includes a crawler body 1, a mounting frame 5 is mounted on the crawler body 1 via a Z-shaped frame 4, a sliding block 6 is slidably mounted on the inner wall of the mounting frame 5, an electric push rod 7 is mounted on the bottom of the inner wall of the mounting frame 5, the telescopic end of the electric push rod 7 is connected to the sliding block 6, and a spray assembly 8 is provided on the sliding block 6.

[0018] The spray assembly 8 includes a fixed housing 801, a fixed pipe 802 on one side of the fixed housing 801, a connecting pipe 803 through one side of the inner wall of the fixed housing 801, and a connecting pipe 804 rotatably connected through the other side of the inner wall of the fixed housing 801. A water guide shell 805 is installed at one end of the connecting pipe 804. Multiple installation pipes 806 are arranged in a ring on the outer wall of the water guide shell 805. An adjusting pipe 807 is threaded on each installation pipe 806. A nozzle is installed at one end of each adjusting pipe 807. One end of the connecting pipe 803 is rotatably connected to one end of the connecting pipe 804 through a sealed bearing. A high-pressure rotary sealing ring is provided at the connection between the connecting pipe 803 and the connecting pipe 804.

[0019] In this embodiment, as Figure 1As shown, a U-shaped frame 2 is provided on the crawler body 1. Both the U-shaped frame 2 and the mounting frame 5 are equipped with photography modules. An LED lighting module is provided on one side of the mounting frame 5 near the top. The crawler body 1 integrates a control host, a motor driver, and an energy storage module. The motor driver is used to drive the bottom tires to move.

[0020] With the above structure, the photography module uses a waterproof camera, which can visually monitor the environment around the crawler, making it easy to keep track of the operation status in the pipeline scene in real time. At the same time, the LED lighting module on the mounting bracket 5 can provide supplementary lighting for the photography module to solve the problem of blurry imaging in dim environments.

[0021] The crawler body 1 integrates a control host, a motor driver, and an energy storage module. The motor driver can directly drive the bottom tires to move, and the energy storage module can provide unified power to all electrical components. The control host coordinates functions such as movement, monitoring, lighting, and spraying to ensure that all components respond in unison.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, a gas detection module is installed on the Z-shaped frame 4, and a lidar is installed on one side of the water guide shell 805.

[0023] Through the above structure, a gas detection module is installed on the Z-shaped frame 4, which can monitor the gas composition and concentration in the crawler's working environment in real time, thereby avoiding the safety risks faced by workers due to exposure to harmful gases. Simultaneously, the lidar on the water guide shell 805 can scan the terrain contour of the working area. Combined with the electric push rod 7, it can automatically adjust the height of the spray assembly 8 according to the pipe diameter, placing it in the center of the pipe to improve cleaning efficiency. The signal output terminals of both the lidar and the gas detection module are electrically connected to the signal input terminal of the control host. The control host has a pre-installed control algorithm that can receive the pipe contour data obtained from the lidar scan, automatically calculate the pipe center coordinates, generate control commands to drive the electric push rod 7, and adjust the spray assembly 8 to the center position of the pipe.

[0024] In this embodiment, as Figure 1 As shown, the sliding block 6 has a circular hole, and the fixing tube 802 is installed in the circular hole. Both ends of the outer wall of the sliding block 6 are provided with sliders, and the front and rear ends of the inner wall of the mounting bracket 5 are provided with corresponding sliding grooves that are adapted to the sliders. The sliders and the sliding grooves form a sliding fit.

[0025] With the above structure, when the height of the spray assembly 8 is adjusted by the electric push rod 7, the electric push rod 7 drives the sliding block 6 to move up and down. The sliders at both ends of the outer wall of the sliding block 6 form a sliding fit with the corresponding matching grooves opened at the front and rear ends of the inner wall of the mounting frame 5. The matching of the sliders and the grooves restricts the movement trajectory of the sliding block 6, preventing it from shifting laterally when moving up and down, ensuring that the spray assembly 8 can be stably adjusted in the preset direction. In addition, a telescopic protective cover can be set between the mounting frame 5 and the sliding block 6 to prevent impurities from entering the groove and affecting the stability of the sliding block 6 when moving up and down.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, a first gear 808 is provided on the outer wall of the connecting pipe 804, a worm gear reducer motor 809 is installed on the inner wall of the fixed shell 801, and a second gear 8010 is installed on the output end of the worm gear reducer motor 809, and the first gear 808 and the second gear 8010 form a meshing transmission cooperation.

[0027] Through the above structure, the meshing transmission of the first gear 808 and the second gear 8010 can smoothly transmit the power of the worm gear reducer motor 809 to the connecting pipe 804, driving the water guide shell 805 and the ring-shaped nozzles to rotate synchronously, thereby realizing rotational rinsing and improving the cleaning effect.

[0028] In this embodiment, as Figure 1 As shown, a support pipe 3 is provided on the crawler body 1, and a flexible hose 9 is inserted through the inner wall of the support pipe 3. One end of the flexible hose 9 is connected to one end of the connecting pipe 803, and the flexible hose 9 is composed of a water pipe and a cable.

[0029] Through the above structure, the support pipe 3 can provide guidance for the hose 9, which is composed of a water pipe and a cable. It can simultaneously supply water and transmit power / signal, deliver working water to the spray assembly 8 and supply power and control signals to related components, such as the worm gear reducer motor 809. One end of the hose 9 is connected to the connecting pipe 803. With the cooperation of the sliding block 6 moving along the mounting frame 5, its flexibility can adapt to the height changes of the spray assembly 8.

[0030] In another embodiment, a cleaning brush 10 of corresponding length can be fitted onto the regulating pipe 807 by means of a clamp, so that after the cleaning brush 10 is installed, its bristles can make close contact with the inner wall of the pipe to be cleaned. When the spray assembly 8 rotates, the cleaning brush 10 can simultaneously perform physical wiping on the inner wall of the pipe, and the water flow sprayed from the nozzle forms a flushing effect, which can remove stubborn stains attached to the inner wall of the pipe and further improve the cleaning effect of the pipe. The bristles of the cleaning brush 10 are made of corrosion-resistant, highly elastic nylon or steel wire material.

[0031] The specific operating procedure of this utility is as follows: First, after the crawler is started, the energy storage module inside the crawler body 1 provides unified power to all electrical components (photography module, LED lighting module, gas detection module, lidar, worm gear reducer motor 809, motor driver, etc.). The control host receives remote control commands through cables and coordinates the operation of each component. The motor driver drives the bottom tires to rotate, moving the crawler into the pipeline and other working areas. After entering the work area, the camera module on the U-shaped frame 2 and the mounting frame 5 performs visual monitoring of the area around the crawler and the working area of ​​the spray assembly 8. If the environment is dark, the LED lighting module near the top of the mounting frame 5 will automatically supplement the light to ensure clear imaging.

[0032] The gas detection module on the Z-shaped frame 4 monitors the gas composition and concentration in the environment in real time. The laser radar on one side of the water guide shell 805 scans the terrain outline of the work area, obtains the pipe diameter data, and feeds the data back to the control host. The control host then drives the electric push rod 7 at the bottom of the inner wall of the mounting frame 5 to extend and retract, which drives the sliding block 6 to move along the mounting frame 5, so that the spray assembly 8 is stably adjusted to the center position of the pipe. During the spraying operation, the hose 9 running through the support pipe 3 on the crawler body 1 supplies water to the spraying assembly 8. The water flows through the connecting pipe 803 into the connecting pipe 804, and then through the water guide shell 805 to the ring-shaped installation pipe 806. Finally, it is sprayed out by the nozzle at one end of the regulating pipe 807. At the same time, the cable in the hose 9 supplies power to the worm gear reducer motor 809 and transmits control signals to drive the motor to run. The second gear 8010 at its output end meshes with the first gear 808 on the outer wall of the connecting pipe 804 to transmit power to the connecting pipe 804, which drives the water guide shell 805 and the nozzle to rotate synchronously, realizing the rotational flushing of the inner wall of the pipe and improving the cleaning coverage.

[0033] Furthermore, the regulating tube 807 with cleaning brush 10 can be replaced as needed. When the cleaning brush 10 rotates with the spray assembly 8, it works in conjunction with the water flow to remove stubborn stains.

[0034] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
