[0035] The invention provides a pipeline cleaning machine.

[0036] Please refer to Figure 1 Figure 2 and Figure 5 In an embodiment of the present invention, the pipeline cleaning machine comprises:

[0037] An upper housing 10, wherein a first accommodating cavity 11 is formed in the upper housing 10;

[0038] a lower housing 20 , the lower housing 20 being connected to the upper housing 10 , and a second accommodating cavity 21 being formed in the lower housing 20 ; and

[0039] The walking mechanism 30 is installed on the upper housing 10 and / or the lower housing 20 .

[0040] The upper housing 10 and the lower housing 20 constitute the main body of the pipe cleaning machine, which is mainly used to provide support and installation space for other components of the pipe cleaning machine, such as the nozzle assembly 70, the walking mechanism 30, the electronic control assembly 40 and the driving assembly 50, and can control the cleaning pipe to move along the pipe, thereby spraying cleaning water to clean the inner wall of the pipe. The walking mechanism 30 can be installed on the upper housing 10 alone, or installed on the lower housing 20 alone, or partially installed on the upper housing 10 and partially installed on the lower housing 20.

[0041] Specifically, the connection between the upper shell 10 and the lower shell 20 can be detachably connected by screws, or detachably connected by snaps, so that when disassembly and maintenance are required, the upper shell 10 or the lower shell 20 can be disassembled separately without disassembly of the entire shell, thereby reducing the workload of disassembly and maintenance.

[0042] In an embodiment of the present application, the pipe cleaning machine includes an electronic control component 40 and a drive component 50. The electronic control component 40 can be detachably installed in the first accommodating chamber 11, and the drive component 50 can be detachably installed in the second accommodating chamber 21. The drive component 50 is electrically connected to the electronic control component 40 and is transmission-connected to the walking mechanism 30.

[0043] In this embodiment, the walking mechanism 30 includes a walking wheel 31 and an auxiliary wheel 32. The walking wheel 31 is installed on the lower housing 20 and is in transmission connection with the driving assembly 50. The auxiliary wheel 32 is installed on the upper housing 10. Specifically, the walking wheel 31 partially extends out of the lower housing 20 so as to be able to abut against the inner wall of the pipeline, while the auxiliary wheel 32 partially extends out of the upper housing 10 and abuts against the inner wall of the pipeline. In this embodiment, the walking wheel 31 is formed as a driving wheel and the auxiliary wheel 32 is formed as a driven wheel. Therefore, when the driving assembly 50 drives the walking wheel 31 to rotate and move along the inner wall of the pipeline, the auxiliary wheel 32 also abuts against the inner wall of the pipeline and moves synchronously with the walking wheel 31. In this way, the friction resistance between the upper housing 10 and the lower housing 20 and the inner wall of the pipeline is small, and the moving process is smoother, so that it is convenient to clean the pipeline.

[0044] It should be noted that, in this embodiment, the number of running wheels 31 can be four, and two are respectively arranged on the opposite sides of the lower casing 20, and the running wheels 31 are arranged at positions adjacent to the two ends of the lower casing 20, while two auxiliary wheels 32 can be provided, and the two auxiliary wheels 32 are respectively arranged on the opposite sides of the upper casing 10, and the two auxiliary wheels 32 can be arranged in the middle position of the upper casing 10, so that the connecting line between the running wheels 31 and the auxiliary wheels 32 on each side of the upper casing 10 and the lower casing 20 can form a triangle-like shape, thereby, in the process of moving along the pipeline, the balance and stability of force can be guaranteed, and at the same time, the addition of additional running wheels 31 or auxiliary wheels 32 can be avoided, thereby saving costs.

[0045] The electric control component 40 is mainly used to provide electric energy for the pipe cleaning machine and to transmit signals; the driving component 50 can convert electric energy into motive energy to ensure the normal operation of the pipe cleaning machine. In actual situations, since the pipe cleaning machine relies on a cleaning pipe connected between the upper housing 10 and the lower housing 20 to spray high-pressure clean water to flush the inner wall of the pipe, the electric control component 40 is installed in the upper housing 10 relatively above the cleaning pipe, and the driving component 50 is installed in the lower housing 20 relatively below the cleaning pipe. In this way, the clean water overflowing from the cleaning pipe can be prevented from affecting the electric control component 40, thereby meeting the high sealing and waterproof requirements of the electric control component 40.

[0046] Therefore, the technical solution of the present invention can drive the pipeline cleaning machine to move along the pipeline to clean the pipeline by installing the walking mechanism 30 on the upper housing 10 and / or the lower housing 20. When it is necessary to maintain the inside of the pipeline cleaning machine, the upper housing 10 or the lower housing 20 connected to the upper housing 10 can be selectively removed to perform targeted maintenance on the pipeline cleaning machine without having to disassemble the entire machine, which not only greatly reduces the difficulty and workload of disassembly and maintenance, but also improves work efficiency.

[0047] In one embodiment of the present application, a middle partition 110 is provided in the first accommodating chamber 11, and the middle partition 110 divides the first accommodating chamber 11 into a first installation chamber 111 and a second installation chamber 112; the electric control assembly 40 includes an electrically connected battery panel 41 and an electric control panel 42, the battery panel 41 is installed in the first installation chamber 111, and is electrically connected to the drive assembly 50, and the electric control panel 42 is installed in the second installation chamber 112. Specifically, the battery panel 41 can be a lithium battery, which has a large battery energy density, a high average output voltage, excellent cycle performance, fast charge and discharge, and a long service life, and can provide sufficient power for the drive assembly 50; the electric control panel 42 includes a switch control panel and a PCB circuit board, which can realize the switch control of the power supply and the transmission of signals. In this embodiment, the first accommodating chamber 11 is divided into two installation chambers by the middle partition 110, so that the electronic control component 40 can be arranged and installed in a more detailed and regular manner, so that when a certain component needs to be maintained or replaced, it can be found quickly and maintenance can be carried out in a targeted manner without disassembling other components, thereby reducing the difficulty of maintenance and improving the efficiency of maintenance work.

[0048] Combined with reference Figure 3In one embodiment of the present application, a first isolation column 113 is provided on one side of the middle partition 110 adjacent to the first installation chamber 111, and a mounting rib 114 is provided on the side wall of the first installation chamber 111 facing the middle partition 110, and the battery panel 41 is detachably clamped between the first isolation column 113 and the mounting rib 114. The first isolation column 113 can be an integral structure with the middle partition 110, or the first isolation column 113 can be connected and fixed to the middle partition 110 by screwing, welding, etc. Similarly, the mounting rib 114 can also be fixed to the upper housing 10 by screwing, welding, etc. Thus, the installation space of the battery panel 41 is defined in the first installation chamber 111 by the first isolation column 113 and the mounting rib 114, so that the battery panel 41 can be clamped and fixed. This installation method makes the battery panel 41 stable to install, will not shake during the movement of the pipeline cleaning vehicle, and is easy to disassemble, and the battery panel 41 can be quickly removed for maintenance. On the other hand, the provision of the first isolation column 113 and the mounting rib 114 forms a gap between the battery panel 41 and the middle partition 110 as well as the shell wall of the upper housing 10, thereby facilitating the discharge of the electric heat generated by the battery panel 41 during operation, while taking into account both the convenience of disassembly and assembly of the battery panel 41 and the heat dissipation performance of the battery panel 41.

[0049] Furthermore, in the present application, a pad 115 is protruding from the bottom wall of the first installation chamber 111, and the battery panel 41 abuts against the upper surface of the pad 115. By providing the pad 115, the battery panel 41 can be spaced apart from the bottom wall of the first installation chamber 111, so as to avoid the battery panel 41 directly abutting against the bottom wall of the first installation chamber 111, thereby facilitating heat dissipation of the battery panel 41.

[0050] Combined with reference Figure 4 In the embodiment of the present application, two second isolation columns 116 are provided on the side wall of the second installation chamber 112 away from the middle partition 110, and the electric control board 42 is clamped between the two second isolation columns 116. The second isolation column 116 is located in the corner of the second installation chamber 112 away from the middle partition 110, so that the electric control board 42 is clamped and fixed in the middle position of the second installation chamber 112. This installation method not only makes the electric control board 42 stable in installation and does not shake during the movement of the pipeline cleaning vehicle, but also facilitates disassembly, and the battery panel 41 can be quickly removed for maintenance and maintenance. On the other hand, a gap is formed between the electric control board 42 and the shell wall of the upper housing 10, which is beneficial to the heat dissipation of the electric control board 42.

[0051] In one embodiment of the present application, the top of the second installation chamber 112 has an opening 1121, and the pipe cleaning machine further includes a cover plate 13, and the cover plate 13 is detachably sealed on the opening 1121. In this embodiment, by covering the cover plate 13, the second installation chamber 112 can be formed into a relatively tight installation space, so that after the electric control board 42 is installed, it can prevent external water from entering the second installation chamber 112 and affecting the electric control board 42, thereby greatly improving the sealing and waterproof performance of the second installation chamber 112.

[0052] Furthermore, the top wall of the upper housing 10 of the present application is provided with a maintenance port 12 connected to the first accommodating cavity 11, and the maintenance port 12 is connected to the opening 1121. The pipe cleaning machine also includes an upper cover 14, and the upper cover 14 is detachably covered on the maintenance port 12. When the upper cover 14 is removed, the battery panel 41 is exposed through the maintenance port 12.

[0053] In actual situations, there is a gap between the battery panel 41 and the upper cover 14. When the battery panel 41 needs to be maintained, the battery panel 41 can be directly maintained by removing the upper cover 14. The gap between the battery panel 41 and the upper cover 14 facilitates air circulation and helps the battery panel 41 to dissipate heat. By closing the upper cover 14, the first accommodating chamber 11 is formed as a tight installation space, so that water will not seep in during the flushing of the pipeline. The combined design of the upper cover 14 and the cover plate 13 takes into account the different requirements of the electric control board 42 and the battery panel 41 for waterproofing and heat dissipation, and the design is more reasonable.

[0054] In the embodiment of the present application, the driving assembly 50 includes a driving motor 51 and a reducer 52 which is transmission-connected to the driving motor 51, and the walking mechanism 30 is transmission-connected to the reducer 52. It can be understood that the number of the driving motor 51 and the reducer 52 should be set accordingly according to the number of the walking wheels 31 of the walking mechanism 30. For example, when there are 4 walking wheels 31, the reducer 52 and the driving motor 51 should also be set accordingly. The output shaft of the driving motor 51 is connected to the reducer 52, and the walking wheels 31 are driven to rotate after being decelerated by the reducer 52, so that the pipeline cleaning machine moves along the pipeline.

[0055] In one embodiment of the present application, a heat dissipation space 22 is also formed in the second accommodating chamber 21, and the heat dissipation space 22 is arranged corresponding to the drive motor 51. In this embodiment, the volume of the heat dissipation space 22 is adapted to the volume of the drive motor 51, the drive motor 51 is located in the middle of the second accommodating chamber 21, and the reducer 52 is located on both sides of the second accommodating chamber 21. With such an arrangement, the interior of the second accommodating chamber 21 is relatively compact, and the design and planning are reasonable, so that the overall volume of the pipe cleaning machine is relatively small and does not occupy too much space. By providing the heat dissipation space 22, a gap is formed between the drive motor 51 and the side wall of the lower housing 20, so that the heat generated during the working process can be discharged in time, avoiding the generation of high temperature and affecting the drive motor 51, thereby increasing the service life of the drive motor 51.

[0056] Further, the pipeline cleaning machine includes a rotatable spray head assembly 70, the spray head assembly 70 includes a mounting seat 72 and a spray head 71 for spraying cleaning water, the mounting seat 72 is fixed to the side of the lower housing 20 facing the upper housing 10, and the spray head 71 is rotatably connected to the end of the mounting seat 72 away from the lower housing 20. In this embodiment, the spray head 71 can be connected to the mounting seat 72 through a small rotary motor and rotate relative to the mounting seat 72 through gear transmission; or the spray head 71 is circumferentially provided with a plurality of spray holes, and the sprays of the plurality of spray holes form vortices, so that the high-pressure spray flow causes the spray head 71 to rotate itself, so that when the spray head 71 moves along the pipeline, the rotating spray head 71 sprays high-pressure cleaning water, so that the cleaning water can flush the inner wall of the pipeline in a 360° direction, thereby greatly improving the degree of cleaning of the pipeline. On the other hand, the gear transmission drives the nozzle assembly 70 to rotate, so different rotation speeds can be set for the nozzle assembly 70 according to different requirements for the cleanliness of the pipeline. For example, when the cleanliness requirement of the pipeline is high, the nozzle assembly 70 can be controlled to rotate slowly to increase the time that the cleaning water stays on the pipeline wall. Otherwise, the nozzle assembly 70 is controlled to rotate quickly, so as to save water efficiently and reasonably.

[0057] In order to further improve the cleaning ability of the pipeline, in one embodiment of the present application, the spray head assembly 70 further includes a cleaning brush (not shown) connected to the liquid spray head 71, and the cleaning brush can rotate relative to the mounting seat 72 and can be pressed against the inner wall of the pipeline. In this embodiment, the rotation of the liquid spray head 71 drives the cleaning brush to rotate as well, so that after the liquid spray head 71 sprays cleaning water, the cleaning brush can scrub the inner wall of the pipeline, thereby greatly improving the cleaning ability of the pipeline cleaning machine.

[0058] In one embodiment, a camera module 60 is further installed on the outer side of the upper housing 10, and the camera module 60 is located at the front end and / or the rear end of the upper housing 10 and is connected to the electronic control component 40. By providing the camera module 60, the inside of the pipeline can be photographed in real time, and the image is transmitted and displayed in real time through the electronic control component 40, thereby detecting the cleanliness of the pipeline, thereby cleaning the pipeline more thoroughly.

[0059] In one embodiment of the present application, the top wall of the lower housing 20 is provided with a disassembly opening 210 communicating with the second accommodating chamber 21, and the pipe cleaning machine further comprises a lower cover 23, and the lower cover 23 is detachably covered on the disassembly opening 210. By providing the lower cover 23, the driving assembly 50 installed in the second accommodating chamber 21 can be protected, and the waterproof performance is good. When the driving assembly 50 needs to be maintained, the maintenance can be carried out directly after the lower cover 23 is removed, without the need to disassemble and assemble other components, so that targeted maintenance can be carried out, which improves the maintenance efficiency and reduces the difficulty of maintenance.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
