Description

Technical Field

[0001] This utility model relates to the field of drainage pipe cleaning technology, specifically to a drainage pipe internal cleaning device. Background Technology

[0002] Drainage pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or elsewhere, any pipe that serves a drainage function should be counted as a drainage pipe. After prolonged use, drainage pipes accumulate impurities on their inner walls, easily causing blockages.

[0003] Existing pipe cleaning devices mostly rely on high-pressure water jets for flushing and suction, which can easily lead to incomplete cleaning and the presence of cleaning residue. Therefore, there is a need for an internal cleaning device for drainage pipes that can both clean impurities inside the pipes and prevent the formation of residue. Utility Model Content

[0004] Therefore, this utility model provides a drainage pipe internal cleaning device, which solves the problem that most pipe cleaning devices rely on high-pressure water flow to flush the pipes, which can easily lead to incomplete cleaning and the presence of cleaning residue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage pipe internal cleaning device, comprising a water injection shell, a water injection port fixedly provided on one side of the water injection shell, a motor fixedly connected to one end of the water injection shell, a connector fixedly connected to the output end of the motor, a water injection pipe fixedly connected to one side of the connector, a flushing assembly fixedly connected to one end of the water injection pipe, the flushing assembly comprising a front flushing cylinder, a connecting pipe, and a rear flushing cylinder, a cleaning component sleeved on the outside of the connecting pipe, the cleaning component comprising a fixed sleeve, two through slots fixedly provided on the outside of the fixed sleeve, a rotating shaft inserted inside the fixed sleeve, a knob fixedly provided at one end of the rotating shaft, a gear sleeved on the outside of the rotating shaft, a turntable provided outside the gear, an arc-shaped rack fixedly provided on one side wall of the turntable, the gear meshing with the arc-shaped rack, multiple arc-shaped grooves opened inside the turntable, two cleaning components provided inside the turntable, each cleaning component comprising a connecting shaft, the connecting shaft passing through the two arc-shaped grooves and slidably connected to the two arc-shaped grooves, a movable plate fixedly sleeved on the outside of the connecting shaft, and a brush plate fixedly provided at one end of the movable plate.

[0006] Preferably, one end of the connector passes through one side wall of the water injection housing and is connected to the side wall of the water injection housing via a bearing.

[0007] Preferably, the water injection pipe passes through the other side wall of the water injection housing and is connected to the other side wall of the water injection housing via a bearing.

[0008] Preferably, the two sides of the fixing sleeve are fixedly connected to the front flushing cylinder and the rear flushing cylinder, respectively.

[0009] Preferably, the rotating shaft is embedded inside the fixed sleeve and connected to the fixed sleeve via a bearing.

[0010] Preferably, the turntable is located inside the fixed sleeve and is slidably connected to the fixed sleeve.

[0011] Preferably, the turntable is sleeved outside the connecting pipe and connected to the connecting pipe via a bearing.

[0012] Preferably, the movable plate passes through the through groove and is slidably connected to the through groove.

[0013] The present invention has the following advantages:

[0014] 1. When the turntable rotates, the arc groove and the connecting shaft cooperate to make the movable plate move longitudinally along the through groove, thereby changing the distance between the two brush plates. This allows the two brush plates to adapt to the diameter of the pipe to be cleaned, preventing the brush plates from not contacting the pipe during subsequent cleaning and thus preventing cleaning dead corners.

[0015] 2. Water is sprayed out through the water outlets on the outside of the front and rear flushing cylinders. The front and rear flushing cylinders pre-flushed the pipes. After the rear flushing cylinder pressurizes and flushes, the brush plate washes the pipes while rotating. The front flushing cylinder rinses the area washed by the brush plate, which greatly improves the cleaning efficiency and ensures the cleanliness of the cleaning. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1 -Appendix Figure 5This utility model provides a drainage pipe internal cleaning device, including a water injection shell 1, a water injection port 2 fixedly provided on one side of the water injection shell 1, a motor 3 fixedly connected to one end of the water injection shell 1, a connector 4 fixedly connected to the output end of the motor 3, a water injection pipe 5 fixedly connected to one side of the connector 4, a flushing assembly 6 fixedly connected to one end of the water injection pipe 5, the flushing assembly 6 including a front flushing cylinder 61, a connecting pipe 62, and a rear flushing cylinder 63, a cleaning assembly 7 sleeved on the outside of the connecting pipe 62, the cleaning assembly 7 including a fixing sleeve 71, two through grooves 72 fixedly provided on the outside of the fixing sleeve 71, the fixing sleeve 7... 1. An internal rotating shaft 74 is inserted, and a knob 73 is fixedly provided at one end of the rotating shaft 74. A gear 75 is sleeved on the outside of the rotating shaft 74, and a turntable 77 is provided on the outside of the gear 75. An arc-shaped rack 76 is fixedly provided on one side wall of the turntable 77. The gear 75 meshes with the arc-shaped rack 76. Multiple arc-shaped grooves 78 are opened inside the turntable 77. Two cleaning components are provided inside the turntable 77. The cleaning components include a connecting shaft 79. The connecting shaft 79 passes through the two arc-shaped grooves 78 and is slidably connected to the two arc-shaped grooves 78. A movable plate 80 is fixedly sleeved on the outside of the connecting shaft 79. A brush plate 81 is fixedly provided at one end of the movable plate 80.

[0026] In this implementation scheme, in order to improve the cleaning effect of the pipeline and prevent cleaning residue, during cleaning, the motor 3 is started. The rotation of the motor 3 drives the water injection pipe 5 to rotate through the connector 4. The rotation of the water injection pipe 5 drives the cleaning component 7 to rotate through the flushing component 6. The rotation of the cleaning component 7 causes the brush plate 81 to rotate and clean the inner wall of the pipeline, improving the cleaning effect and preventing cleaning dead corners. At the same time, water enters the water injection housing 1 through the water inlet 2 through the water inlet device, and then enters the flushing component 6 through the water injection pipe 5. Water is sprayed out through the water outlets on the outside of the front flushing cylinder 61 and the rear flushing cylinder 63. The front flushing cylinder 61 and the rear flushing cylinder 63 pre-flushed the pipeline. After the rear flushing cylinder 63 pressurized flushed, the brush plate 81 scrubbed the pipeline while rotating. The front flushing cylinder 61 rinsed the area scrubbed by the brush plate 81, which greatly improved the cleaning efficiency and ensured the cleanliness of the cleaning.

[0027] To achieve the rotation of the flushing assembly 6, the device employs the following technical solution: one end of the connector 4 penetrates one side wall of the water injection housing 1 and is connected to the side wall of the water injection housing 1 via a bearing; the water injection pipe 5 penetrates one side wall of the water injection housing 1 and is connected to the side wall of the water injection housing 1 via a bearing; the motor 3 is started, and the rotation of the motor 3 drives the rotation of the water injection pipe 5 through the connector 4; the rotation of the water injection pipe 5 drives the rotation of the cleaning assembly 7 through the flushing assembly 6; when the flushing assembly 6 rotates, water is sprayed out from the outlet holes outside the front flushing cylinder 61 and the rear flushing cylinder 63; the front flushing cylinder 61 and the rear flushing cylinder 63 pre-flushing the pipe.

[0028] To enable the brush plate 81 to contact the inner walls of pipes with various diameters, the device employs the following technical solution: the fixed sleeve 71 is fixedly connected to the front flushing cylinder 61 and the rear flushing cylinder 63 on both sides, respectively; the rotating shaft 74 is embedded inside the fixed sleeve 71 and connected to the fixed sleeve 71 via a bearing; the turntable 77 is located inside the fixed sleeve 71 and slidably connected to the fixed sleeve 71; the turntable 77 is sleeved on the outside of the connecting pipe 62 and connected to the connecting pipe 62 via a bearing; and the movable plate 80 passes through the through groove 72 and connects to the through groove 72. The sliding connection allows for the rotation of knob 73. Knob 73 rotates, which in turn drives gear 75 via shaft 74. Gear 75 rotates, which in turn drives turntable 77 via arc-shaped rack 76. Turntable 77 rotates, and through the engagement of arc-shaped groove 78 and connecting shaft 79, the movable plate 80 moves longitudinally along through groove 72. This changes the distance between the two brush plates 81, allowing them to adapt to the diameter of the pipe to be cleaned. This prevents the brush plates 81 from not contacting the pipe during subsequent cleaning, thus preventing cleaning dead zones.

[0029] The usage process of this utility model is as follows: When using this utility model, the motor 3 is connected to an external power source, and the water inlet 2 is connected to a water inlet device. When cleaning pipes of different diameters, the knob 73 is rotated. The rotation of the knob 73 drives the gear 75 to rotate through the rotating shaft 74. The rotation of the gear 75 drives the turntable 77 to rotate through the arc-shaped rack 76. When the turntable 77 rotates, the movable plate 80 moves longitudinally along the through groove 72 through the cooperation of the arc-shaped groove 78 and the connecting shaft 79, thereby changing the distance between the two brush plates 81. This allows the two brush plates 81 to adapt to the diameter of the pipe to be cleaned, preventing the brush plates 81 from not contacting the pipe during subsequent cleaning, and thus preventing cleaning dead corners. During cleaning, the motor 3 is started, and the rotation of the motor 3 drives the connecting piece 4 to rotate. The water injection pipe 5 rotates, which in turn drives the cleaning component 7 to rotate via the flushing component 6. The rotation of the cleaning component 7 causes the brush plate 81 to rotate and clean the inner wall of the pipe, improving the cleaning effect and preventing cleaning dead corners. At the same time, water enters the water injection housing 1 through the water inlet 2 through the water inlet device, and then enters the flushing component 6 through the water injection pipe 5. The water is sprayed out through the water outlets on the outside of the front flushing cylinder 61 and the rear flushing cylinder 63. The front flushing cylinder 61 and the rear flushing cylinder 63 pre-flushed the pipe. After the rear flushing cylinder 63 pressurized flushed, the brush plate 81 scrubbed the pipe while rotating, and the front flushing cylinder 61 rinsed the area scrubbed by the brush plate 81, greatly improving the cleaning efficiency and ensuring the cleanliness of the cleaning.

[0030] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
