Description

Technical Field

[0001] The present application relates to the technical field of drainage pipeline repair spraying, and specifically relates to a municipal drainage pipeline spraying machine. Background Technique

[0002] Pipe repair generally includes two types: excavation type and trenchless type. Among them, the trenchless type is widely used because of its small damage to the road and low cost. The trenchless repair methods include the in-situ spraying method of polyurea. This method sprays modified polyurea materials on the inner wall of the pipeline, the inner wall of the well chamber or the surface of other pools through the spraying method. The spraying material undergoes a chemical reaction on the surface to be sprayed and quickly solidifies, thereby forming a polymer lining with a certain thickness on the inner wall of the pipeline, thus solving the problem of leakage of the pipeline and the well chamber.

[0003] The above operation method requires the use of a pipeline spraying machine. In related technologies, the spraying machine mainly includes a box body, a feeding mechanism containing paint, a power mechanism arranged inside the box body, and a nozzle. The power mechanism includes a high-pressure pump connected to the feeding mechanism, and the high-pressure pump is connected to the nozzle through a hose. When the spraying machine is in use, the staff holds the nozzle and sprays the paint on the inner wall of the pipeline or the inner wall of the well chamber. A municipal drainage pipeline spraying machine is disclosed in Chinese Patent (Publication No.: CN 213468293 U), which is convenient for the storage of the hose. However, when spraying and repairing the inside of the pipeline in the above document, the staff needs to hold the nozzle and rotate it inside the pipeline to spray and repair the inner wall of the pipeline in all directions, and spraying needs to be carried out repeatedly to ensure uniform spraying, resulting in a slow spraying and repairing efficiency. Summary of the Utility Model

[0013] Adopting the above technical solution, the two spray nozzles and the brush can rotate 360° inside the drainage pipe, effectively enhancing the spraying range and the brushing area.

[0014] Further, the connecting plate is in the shape of a circular hollow with the left side missing, and a fixing hole for fixing it to the outside of the I-shaped cylinder is formed on the right side of the connecting plate.

[0015] Adopting the above technical solution, the connecting plate can be fixed to the outside of the I-shaped cylinder.

[0016] Further, the left end of the driving motor is fixed to the left side wall inside the I-shaped cylinder, and the fixing hole corresponds to the gear ring.

[0018] Further, a connecting hole is formed on the left side of the I-shaped cylinder, and the connecting pipe penetrates into the interior of the connecting hole and is fixed thereto.

[0019] Adopting the above technical solution, the connecting pipe can be fixed to the inside of the I-shaped cylinder, so as to drive the connecting pipe to rotate.

[0020] Further, a circular hole is formed on the left side of the circular plate, and the I-shaped cylinder is fixed inside the circular hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figures 1 to 2 , a municipal drainage pipe spraying machine in this embodiment includes a box body 1. The left side wall of the box body 1 is rotatably connected with a winding roller 2 through a bearing. The outer surface of the winding roller 2 is wound with a spraying pipe 3. The left end of the spraying pipe 3 is fixedly connected with a rotary joint 4. The other end of the rotary joint 4 is fixed with a connecting pipe 5. Both the upper and lower ends of the connecting pipe 5 are fixedly connected and communicated with a spray head 6. The outer surface of the connecting pipe 5 is provided with a brushing component.

[0032] Moreover, a water pump is fixed to the liquid outlet end of the box body 1, and the output end of the water pump is fixed to the other end of the spraying pipe 3, so as to convey the paint in the box body 1 into the nozzle 6.

[0033] Please refer to Figures 2 to 5 , in this embodiment, the brushing assembly includes two brushes 64, two sliding rods 62, a sleeve rod 63 fixedly installed at the opposite ends of the two brushes 64, a stopper 610 fixedly installed at the opposite ends of the two sliding rods 62, a circular plate 61 fixedly installed on the opposite sides of the two sliding rods 62, and a rotating structure fixedly installed inside the circular plate 61 for driving its rotation.

[0034] Wherein, circular holes are formed at the opposite ends of the two sleeve rods 63, and the sliding rods 62 penetrate through the circular holes into the interior of the sleeve rods 63 and are slidably connected thereto, so that the sliding rods 62 can be retracted into the interior of the sleeve rods 63, and the diameter of the stopper 610 is larger than that of the circular holes, thereby preventing the sleeve rods 63 from falling off the outside of the sliding rods 62.

[0035] Moreover, spring 611 is fixedly installed on the inner cavity walls of the two sleeve rods 63, and the other ends of the two springs 611 are respectively fixedly installed at the opposite ends of the two sliding rods 62. When the sleeve rods 63 are located above the circular plate 61, the spring 611 exerts a resistance force on them, preventing them from sliding down due to inertia and the sliding rods 62 moving into their interior, resulting in the brushes 64 not being easily abutted against the top end of the inner cavity of the pipeline.

[0036] Please refer to Figures 3 to 4 , in this embodiment, the rotating structure includes an I-shaped cylinder 65, a gear 68, a connecting plate 66 fixedly installed on the left side wall inside the I-shaped cylinder 65, a gear ring 67 fixedly installed on the right side wall inside the connecting plate 66, and a driving motor 69 fixedly installed at the front end of the gear 68.

[0037] Secondly, the connecting plate 66 is in the shape of a circular hollow with the left side missing, and a fixing hole for fixing it to the outside of the I-shaped cylinder 65 is formed on the right side of the connecting plate 66, so that the connecting plate 66 can be fixed to the outside of the I-shaped cylinder 65.

[0038] At the same time, the left end of the driving motor 69 is fixedly installed on the left side wall inside the I-shaped cylinder 65, so that the connecting plate 66 can hide the gear ring 67, the gear 68 and the driving motor 69. The fixing hole corresponds to the gear ring 67, and the I-shaped cylinder 65 can penetrate into the inside of the gear ring 67.

[0039] In addition, a connecting hole is formed on the left side of the I-shaped cylinder 65, and the connecting pipe 5 penetrates into the inside of the connecting hole and is fixed thereto, facilitating its fixation to the outside of the connecting pipe 5. When the gear ring 67 drives the connecting plate 66 to rotate, the connecting plate 66 can drive the connecting pipe 5 to rotate through the I-shaped cylinder 65, so that the connecting pipe 5 can drive the two nozzles 6 to perform circular motion.

[0040] In addition, a circular hole is provided on the left side of the circular plate 61, and the I-shaped cylinder 65 is fixed inside the circular hole so that the circular plate 61 can be fixed outside the I-shaped cylinder 65, enabling the I-shaped cylinder 65 to drive the circular plate 61 to rotate. The circular plate 61 can drive two brushes 64 to rotate through the sleeve rod 63 and the slide rod 62, and the two brushes 64 smear the inner cavity wall of the drainage pipe.

[0041] It should be noted that all the electronic components mentioned in the text are well-known to the public in the prior art. The control mode of this new type of implementation is controlled by a controller, and the electrical components mentioned in the text are all connected to the controller and the power supply. The control circuit of the controller can be realized by simple programming by those skilled in the art, and the provision of the power supply also belongs to the well-known knowledge in this field. Therefore, the control mode and circuit connection of this new type of utility model will not be explained in detail.

[0042] The working principle of the above embodiment is as follows:

[0043] During use, when the two spray heads 6 spray and repair the inner cavity wall of the drainage pipe, the two brushes 64 are in contact with the inner cavity wall of the drainage pipe, enabling the two brushes 64 to brush the paint sprayed by the spray heads 6. The driving motor 69 drives the gear 68 to rotate, so that the gear 68 can mesh with the gear ring 67, causing the gear ring 67 to rotate. During the rotation of the gear ring 67, it drives the I-shaped cylinder 65 to rotate, and the I-shaped cylinder 65 drives the two spray heads 6 to rotate inside the drainage pipe through the connecting pipe 5, so that the two spray heads 6 can spray paint on the inner cavity wall of the drainage pipe in all directions, effectively increasing the spraying range. Without the need for staff to manually rotate the spray heads 6, the spraying efficiency can be effectively improved.

[0044] Moreover, when the I-shaped cylinder 65 drives the connecting pipe 5 to rotate, it also drives the circular plate 61 to rotate, enabling the circular plate 61 to drive the two slide rods 62 to rotate 360° inside the drainage pipe. That is, the two slide rods 62 drive the two brushes 64 to rotate inside the drainage pipe through the two sleeve rods 63, so that the two brushes 64 can evenly brush the paint on the inner cavity wall of the drainage pipe, effectively improving the uniformity of paint smearing and thus improving the repair efficiency of the drainage pipe.
