[0002] Manhole repair equipment is a type of machinery used to repair defects such as cracks, damage, corrosion, and blockages inside manholes. This equipment typically employs trenchless technology, operating inside the manhole to avoid the damage to surface traffic and the surrounding environment caused by traditional excavation repair methods. In the existing technology, when using repair equipment to repair the cracks inside the inspection well, the repair equipment must first be placed inside the inspection well, and then the equipment nozzle is operated to spray repair material onto the crack. However, there is usually clump of dirt inside the inspection well, which will hinder the movement of the repair equipment and thus affect its progress. Therefore, we propose an inspection well repair equipment to solve the above problems. Utility Model Content

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are merely one embodiment of this utility model, and not all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Specific embodiments are as follows: A kind of maintenance well repair equipment, such as Figures 1-5 The system includes an outer casing 1, with a dirt cleaning module 2 installed on one side of the casing 1. A support 3 is installed between the outer casing 1 and the dirt cleaning module 2, and a paint spray pipe 4 is installed on the surface of the support 3. The support 3 fixes the paint spray pipe 4 to the surface of the dirt cleaning module 2. The dirt cleaning module 2 drives the paint spray pipe 4 to enter the repair and maintenance well simultaneously. The dirt cleaning module 2 scrapes away the dirt on the inner wall of the repair and maintenance well, and the paint spray pipe 4 sprays out the repair paint. This allows the dirt inside the maintenance well to be scraped and cleaned before repair, avoiding the problem of dirt obstructing the movement of the equipment.

[0018] The dirt cleaning module 2 includes a motor 21, a rotating rod 22, an upper connecting seat 23, a lower connecting seat 24, several sets of fixing rods 25, and several sets of scrapers 26. The motor 21 is located inside the motor 21, the rotating rod 22 is located at the output end of the motor 21, and the rotating rod 22 is rotatably connected to the outer casing 1. The upper connecting seat 23 is located at the end of the rotating rod 22, the lower connecting seat 24 is located on one side of the surface of the upper connecting seat 23, several sets of fixing rods 25 are located on the side of the lower connecting seat 24, and several sets of scrapers 26 are respectively located at one end of several sets of fixing rods 25. In use, the scraper 26 is inserted into the manhole, and the motor 21 is started. The motor 21 begins to rotate, which causes the rotating rod 22 to rotate. The scraper 26, fixed at the end of the rotating rod 22, rotates synchronously. During the rotation, the scraper 26 scrapes away the dirt on the inner wall of the manhole. While scraping, the scraper 26 is pushed into the manhole. The paint spray pipe 4 moves synchronously with the rotating rod 22. The scraper 26 serves to clean the path inside the manhole for the paint spray pipe 4, preventing the dirt inside the manhole from affecting the movement of the paint spray pipe 4.

[0019] Several sets of scrapers 26 are evenly distributed around the lower connecting seat 24, and one side of the cutting edge of the scrapers 26 is inclined. The inclined cutting edge can reduce the contact area between the scraper 26 and the dirt on the inner wall of the inspection well, thereby reducing the resistance during scraping, making it easier for the scraper 26 to penetrate into the dirt, and thus improving the scraping efficiency of the scraper 26.

[0020] The bottom of the lower connecting seat 24 has an inverted conical structure, and there is a gap between the two adjacent sets of scrapers 26. When scraping off the dirt on the inner wall of the inspection well, some of the scraped dirt is moved out through the gap between the two adjacent sets of scrapers 26, and the remaining dirt concentrated on one side of the lower connecting seat 24 is moved out from between the connecting rods 32 along the inverted conical slope of the lower connecting seat 24. This can avoid excessive dirt accumulation at the front end of the cutting edge of the scraper 26, thus affecting the movement of the scraper 26.

[0021] The bracket 3 includes several sets of connecting pipes 31 and several sets of connecting rods 32. The several sets of connecting pipes 31 are equally spaced on the surface of the rotating rod 22. The connecting pipes 31 are rotatably connected to the rotating rod 22. The several sets of connecting rods 32 are respectively connected between the outer shell 1 and the connecting pipes 31, and between two adjacent sets of connecting pipes 31. The several sets of connecting pipes 31 and connecting rods 32 work together to support the surface of the rotating rod 22, reducing the pressure at the connection between the rotating rod 22 and the outer shell 1, thereby extending the service life of the device.

[0022] The bracket 3 also includes several sets of limiting rings 33, which are respectively set on the surface of several sets of connecting pipes 31. Each set of limiting rings 33 has an opening on one side. The paint spray pipe 4 is sequentially inserted into the inside of the limiting rings 33. The several sets of limiting rings 33 cooperate to fix the connecting module 5 on the surface of the rotating rod 22, thus preventing the paint spray pipe 4 from shifting randomly and thus hindering the normal operation of the rotating rod 22.

[0023] A connecting module 5 is provided between the connecting pipe 31 and the connecting rod 32. The connecting module 5 includes several sets of bolts 51. The upper connecting seat 23 and the lower connecting seat 24 are fixedly connected through the connecting module 5. When repairing different types of inspection wells, the several sets of bolts 51 are removed from the inside of the upper connecting seat 23 and the lower connecting seat 24 in sequence. The assembly of the lower connecting seat 24, the fixing rod 25 and the scraper 26 is removed. Then, the scraper 26 that is suitable for the inspection well is replaced. One side of the lower connecting seat 24 is attached to the surface of the upper connecting seat 23. Then, the several sets of bolts 51 are screwed back into the inside of the upper connecting seat 23 and the lower connecting seat 24. In this way, the scraper 26 that is suitable for different types of inspection wells can be replaced to ensure that the scraper 26 can fit into the inside of the inspection well, thereby achieving effective scraping and cleaning.

[0024] The connecting module 5 also includes a limiting block 52 and a limiting groove 53. The limiting block 52 is located on the top of the lower connecting seat 24, and the top of the limiting block 52 is chamfered. The limiting groove 53 is located at the bottom of the upper connecting seat 23. When the lower connecting seat 24 is installed on one side of the surface of the upper connecting seat 23, the limiting block 52 is inserted into the limiting groove 53 under the action of the lower connecting seat 24. This can help align the installation of the lower connecting seat 24, making it easier to screw the bolt 51 into the upper connecting seat 23 and the lower connecting seat 24. The chamfered design can guide the insertion of the limiting block 52, so that the limiting block 52 can be accurately inserted into the limiting groove 53, thereby reducing the installation difficulty.

[0025] Handles 6 are provided on both sides of the outer casing 1. Rubber pads 7 are fitted on the surface of the handles 6. Several sets of annular rubber strips are formed on the surface of the rubber pads 7, and the several sets of annular rubber strips are evenly distributed. The two sets of handles 6 work together to facilitate the operation of the device by hand. The rubber pads 7 on the surface of the handles 6 increase the friction between the handles 6 and the operator's hand, making it more stable for the operator to hold. At the same time, the handles 6 can also cushion the operator's hand, reducing the impact on the operator's hand when the device is operating and improving the operator's comfort.

[0026] The outer casing 1 has several sets of heat dissipation holes 8 around its perimeter, and each set of heat dissipation holes 8 is equipped with a heat dissipation filter 9 inside. When the motor 21 is running, the several sets of heat dissipation holes 8 can effectively dissipate heat from the motor 21, preventing the motor 21 from degrading due to overheating. The heat dissipation filter 9 can effectively block dust and debris from entering the interior of the motor 21, preventing dust and debris from hindering the heat dissipation of the motor 21, thereby improving the service life of the motor 21.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
