[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, an embodiment of the present invention proposes an inner wall cleaning device for repairing drainage pipes in municipal pipe network projects, including a shell 1, having a channel with an opening at one end, a baffle plate being arranged in the channel to separate the channel into an installation bin 101 and a water storage bin 102, the water storage bin 102 being provided with an installation through hole 103, both ends of the installation through hole 103 respectively pass through the baffle plate and the shell 1, for connecting the installation bin 101 with the outside of the shell 1; a cleaning unit, including a driving source 3 arranged in the installation bin 101 and a cleaning piece arranged at the output end of the driving source 3, the cleaning piece being located at the front end of the shell 1, for cleaning the inner wall of the pipe body 100 a spray unit, including a water guide pipe 5 having one end arranged in the water storage bin 102 and the other end connected to an arc pipe 501, a plurality of groups of nozzles 502 being evenly distributed on the arc pipe 501; a moving unit, arranged on the periphery of the shell 1, for driving the shell 1 to move.

[0026] The detailed working process of this embodiment is as follows: the installation bin 101 is used to install the driving source 3, the water storage bin 102 is used to store water for use by multiple groups of nozzles 502, and the water pipe 5 is located in the water storage bin 102 so that a pressure water pump can deliver high-pressure water flow to multiple groups of nozzles 502. The sprayed water is poured on the inner wall of the pipe, and the water flow will flow along the inner wall to the bottom of the pipe. In this process, the solidified body attached to the inner wall can be attacked to soften it, which is convenient for cleaning. The moving unit is used to support the shell 1 to move in the pipe. The moving unit can be connected to the driving device by transmission, or the shell 1 can be driven to move in the pipe by external force.

[0027] The driving source 3 in the cleaning unit drives the cleaning piece to rotate to clean the inner wall of the pipe, and at the same time, the multiple groups of nozzles 502 in the spraying unit spray high-pressure water to flush the inner wall of the pipe. The cleaning piece rotates to clean the inner wall of the pipe, and at the same time, the multiple groups of nozzles 502 spray high-pressure water to flush the inner wall of the pipe. The impurities solidified on the inner wall of the pipe can be softened by water flushing. After cleaning by the cleaning piece, the impurities attached to the inner wall of the pipe can be washed away by the high-pressure water flow. The two complement each other to effectively improve the cleaning data. While cleaning, the shell 1 moves forward in the pipe to clean the entire pipe.

[0028] The driving source 3 in this embodiment is a motor. In other embodiments, a suitable driving unit can be selected according to actual conditions.

[0029] like Figure 3 As shown, a driving shaft 301 is provided at the output end of the driving source 3, and the driving shaft 301 passes through the mounting through hole 103. The cleaning member includes a driving disk 6 provided at one end of the driving shaft 301, and a plurality of support arms 601 evenly distributed on the driving disk 6, and each support arm 601 is provided with a scraper 606.

[0030] like Figure 2 and Figure 4 As shown, a mounting groove 6011 is provided at one end of each arm 601 away from the driving disk 6, and travel grooves 6012 are provided on both sides of the arm 601, and the travel grooves 6012 are connected to the mounting grooves 6011. Limit blocks 605 are fixedly arranged on both sides of each scraper 606, and the scraper 606 is movably arranged in the mounting groove 6011, and each limit block 605 is respectively located in the corresponding travel groove 6012, wherein a plurality of groups of compression springs 604 are arranged at the bottom of the travel groove 6012, and the plurality of groups of compression springs 604 abut against the bottom of the scraper 606, and each scraper 606 abuts against the inner wall of the pipe body 100 under the elastic force of the corresponding compression spring 604.

[0031] The detailed working process of this embodiment is as follows: the driving shaft 301 passes through the mounting through hole 103, and one end extends out of the shell 1 to be connected with the cleaning piece. The scraper 606 is movably arranged in the mounting groove 6011. With the cooperation of the limit block 605 and the travel groove 6012, the scraper 606 moves in the mounting groove 6011 along the direction of the travel groove 6012. At the same time, multiple groups of compression springs 604 are arranged at the bottom of the travel groove 6012. Each scraper 606 abuts against the inner wall of the pipe body 100 under the elastic force of the compression spring 604, which can ensure that during the rotation process, each scraper 606 can abut against the inner wall of the pipe body 100, and the debris attached to the inner wall of the pipe body 100 can be scraped and cleaned.

[0032] like Figure 5 As shown, each arm 601 extends along its length direction to be connected to the driving disk 6 and forms an angle with the axis of the driving disk 6 .

[0033] The detailed working process of this embodiment is as follows: each arm 601 forms an angle with the axis of the driving disk 6, so that the scraper 606 installed on the arm 601 is in an inclined state. The inclined scraper 606 can better adapt to the movement state of the driving disk 6, thereby achieving a better effect when scraping debris on the inner wall surface of the pipeline. At the same time, when rotating to scrape the inner wall surface of the pipeline, the resistance can be reduced. When the scraper 606 is parallel to the axis of the driving disk 6, the area cleaned at the same time is the largest, and the resistance is also the largest. Within a certain range, the larger the angle formed by the scraper 606 and the axis of the driving disk 6, the smaller the resistance, but the smaller the area cleaned at the same time. In this embodiment, the angle formed by the arm 601 and the axis of the driving disk 6 is 30°.

[0034] like Figure 4 As shown, the scraper 606 includes multiple groups of scrapers 602 and multiple groups of cleaning brushes 603 , and each scraper 602 and each cleaning brush 603 are adjacently arranged on the corresponding support arm 601 .

[0035] The detailed working process of this embodiment is as follows: the scraper 602 cooperates with the cleaning brush 603, and the scraper 602 can directly remove dirt, grease, dry tree roots and other impurities attached to the pipe wall by physical scraping. This direct scraping effect is more effective than simple flushing, especially for cleaning stubborn dirt. After the scraper 602 scrapes, it is cleaned again by the cleaning brush 603 to further improve the cleaning quality. Multiple sets of scrapers 602 and multiple sets of cleaning brushes 603 are arranged at intervals to effectively improve the cleaning effect.

[0036] like Figure 5 As shown, each nozzle 502 extends along its length direction and is connected to the arc tube 501 , and forms an angle with the axis of the driving disk 6 .

[0037] The detailed working process of this embodiment is as follows: the nozzle 502 is tiltedly arranged on the arc tube 501, and the water flow sprayed by the nozzle 502 directly impacts the contact range between the scraper 606 and the inner wall of the pipe. In the process of cleaning the pipe wall, the scraper 606 is used for physical cleaning to remove most of the dirt, sediment or other impurities attached to the pipe wall. This physical cleaning method is particularly effective for removing stubborn stains. At the same time, the nozzle 502 is used for water washing, and the tiny particles or residues that are loosened by the scraper 602 but have not yet separated from the pipe wall can be further removed through the hydraulic flushing effect. The benefit of water washing is not only its direct cleaning effect, but also that it can create a smoother working environment for the scraper 606 to clean. The wet pipe wall can reduce friction, making the scraper 606 smoother when moving, which helps to avoid unnecessary damage to the pipe wall caused by the scraper 606. At the same time, water can also take away the debris and dust generated by the cleaning of the scraper 606 to prevent them from being deposited on the pipe wall again.

[0038] like Figure 1 As shown, the mobile unit includes a plurality of support bases 2 evenly distributed on both ends of the housing 1 , and each support base 2 is provided with a roller 201 .

[0039] The detailed working process of this embodiment is as follows: the roller 201 is used to support the housing 1 to move in the pipeline. The roller 201 can be connected to the driving device by transmission, or the housing 1 can be driven to move in the pipeline by external force.

[0040] like Figure 2 As shown, a fan-shaped scraper 4 is provided at the bottom of the shell 1 . The scraper 4 is located at one end close to the installation bin 101 , and the arc-shaped end of the scraper 4 abuts against the inner wall of the pipe body 100 .

[0041] like Figure 6 As shown, a conical surface 401 is provided on one side of the scraper 4 close to the water storage tank 102 , and a rubber block 402 is provided on the conical surface 401 .

[0042] The detailed working process of this embodiment is as follows: the arc-shaped end of the scraper 4 abuts against the inner wall of the pipe body 100, and the scraper 4 moves forward synchronously as the shell 1 moves forward, so that the accumulated water and debris in the pipe can be removed from the pipe; under the setting of the rubber block 402, the contact gap with the inner wall of the pipe body 100 is reduced to prevent water from flowing back to the cleaned area during the forward movement.

[0043] like Figure 2 As shown, an air hole 1013 is formed at one end of the shell 1 away from the cleaning piece, and a heat dissipation baffle 1012 is provided at the air hole 1013.

[0044] The detailed working process of this embodiment is as follows: the function of the air vents 1013 and the heat dissipation baffle 1012 is to prevent the driving source 3 in the installation compartment 101 from generating severe heat during operation, thereby affecting the use.

[0045] The implementation principle of the embodiment of the present application is: first, fill the water storage tank 102 with water, and then energize the driving source 3 to drive the multiple groups of scrapers 606 to rotate, pushing the shell 1 forward in the pipeline, and the multiple groups of scrapers 606 clean the inner wall of the pipeline. At the same time, multiple groups of nozzles 502 spray high-pressure water flow to further remove tiny particles or residues loosened by the scraper 602 but not yet separated from the pipe wall. During the forward movement, the scraper 4 can take the accumulated water and debris in the pipeline away from the pipeline, and the cleaning work is completed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
