Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning devices, in particular to a pipeline cleaning device based on water spray power. Background Art

[0002] Pipeline cleaning is one of the important tasks to maintain the normal operation of the pipeline system. Cleaning the pipeline can effectively remove the sediment and dirt in the pipeline, improve the flow of the pipeline, reduce the occurrence of pipeline blockage, and ensure the normal operation of the pipeline for a long time; regular pipeline cleaning can also reduce the occurrence of pipeline corrosion and wear, extend the service life of the pipeline, and reduce the cost of repairing and replacing the pipeline.

[0003] Existing pipeline cleaning devices are basically driven by electricity to clean pipelines. Chinese patent document CN115193832A discloses a pipeline cleaning device, including a rotating body, a supporting body and a driving body for contacting the pipe wall and driving the rotating body and the supporting body to slide along the pipeline, the supporting body is arranged in a cylindrical shape, a rotating motor for driving the rotating body to rotate is arranged on the supporting body, a plurality of flushing nozzles for flushing the pipe wall are arranged on the rotating body along its circumferential direction, a main pipe is rotatably connected on the end face of the rotating body away from the rotating motor, a plurality of arc-shaped supporting blocks are evenly arranged on the supporting body along its circumferential direction, and a plurality of pulleys for contacting the pipe wall are arranged on the supporting blocks. When cleaning the pipeline, first place the entire device in the pipeline to be cleaned and make the pulley arranged on the support block contact the pipe wall. Then use the external pressurizing equipment to input the pressurized water into the rotating body through the main pipe and output it through the flushing nozzle to flush the pipe wall. Then start the rotating motor to rotate the rotating body. Later, use the driving body to drive the entire device to slide along the pipeline to complete the cleaning of the pipeline.

[0004] The technical solution in the above patent document drives the flushing nozzle to rotate by a rotating motor, and uses a driving device to drive the entire device to slide along the pipeline. However, the structure of the above technical solution is relatively complex, and the working environment is humid and watery. Once a failure occurs due to leakage caused by inadequate sealing, it will affect the normal operation of the entire device. In addition, electric components are prone to oxidation and rust when they are in a humid environment for a long time.

[0046] The technical solution provided by the utility model has the following advantages:

[0047] 1. The utility model is a pipeline cleaning device based on water spray power, comprising a shell, a water inlet tank, a sealed bearing, a main pipe and a water spray pipe assembly; wherein the shell has an inner cavity, and a first pipe inlet is provided at the bottom end; the water inlet tank is installed inside the inner cavity of the shell, and has a closed inner cavity, the bottom end of the closed inner cavity is fixedly connected to the inner side of the bottom wall of the shell, and a second pipe inlet opposite to the first pipe inlet is provided, and a water outlet is provided at the top of the closed inner cavity; the sealed bearing is installed inside the closed inner cavity, and a water containing space is formed between the sealed bearing and the top surface of the sealed inner cavity, and the water containing space is connected to the water outlet; one end of the main pipe is connected to an external water pipe, and the other end extends into the water inlet tank and is connected to the water containing space, and the outer wall of the main pipe is sealed and connected to the inner ring of the sealed bearing; one end of the water spray pipe assembly is connected to the water outlet, and the other end extends out of the shell by a certain length, and the extended end is bent in an arc to change the direction of water spraying.

[0049] That is to say, the water-spray-powered pipe cleaning device of the utility model directly drives the outer shell to rotate through the reaction force of the water spraying outward, thereby driving the water spray pipe assembly to rotate without the need for electric drive. Therefore, it is safer and is not constrained by electricity, and can clean the inner cavity of a longer pipe.

[0055] When the pipe cleaning device based on water spray power of the utility model is used for cleaning a pipe with one end closed, after the cleaning device moves to the closed end of the pipe and the reversing rod hits the inner wall of the closed end of the pipe, the impact force of hitting the inner wall of the closed end of the pipe drives the reversing rod to move toward the inside of the shell, and the movement of the reversing rod drives the main reversing gear to rotate through the linkage structure, and the main reversing gear drives the slave reversing gear meshing with it to rotate, and the slave reversing gear is fixedly connected to the water spray pipe, and the rotation of the slave reversing gear drives the water spray pipe to turn, so that the direction of the water outlet end of the water spray pipe located outside the shell can be adjusted, thereby changing the direction of action of the driving force of the water spray pipe, and the driving force after changing the direction drives the entire pipe cleaning device to move in the opposite direction until it reaches the outlet at one end of the pipe.

[0056] 5. The utility model is a pipeline cleaning device based on water spray power, and the linkage structure includes an axial slide groove, a first limit piece, a rotating slide groove and a second limit piece; wherein the axial slide groove is arranged on the outer wall of the reversing rod, and the first limit piece has a first slide column that can extend into the axial slide groove and is slidably connected thereto; the rotating slide groove is arranged on the outer wall of the reversing rod, and its position is opposite to the axial slide groove in front and back and is not connected to each other, and the second limit piece has a second slide column that can extend into the rotating slide groove and is slidably connected thereto; when the reversing rod moves axially, the first slide column slides in the axial slide groove to prevent the reversing rod from rotating, and the second slide column slides in the rotating slide groove to drive the main reversing gear to rotate.

[0087] like Figure 7-8As shown, the water spray pipe assembly in this embodiment includes a water spray pipe 2 and a rotary joint; wherein the water spray pipe 2 is rotatably mounted on the housing 1, with one end extending outward from the housing 1 and the other end located inside the housing 1; the water outlet end of the water spray pipe 2 extending out of the housing 1 faces obliquely backward; the rotary joint 21 has a rotatable end 23 and a fixed end 24, the rotatable end 23 is rotatably sealedly connected to the other end of the water spray pipe 2, and the fixed end 24 is connected to the water outlet of the water inlet tank 3 through a connecting pipe 22. The water outlet end of the water spray pipe 2 extending out of the housing 1 faces obliquely backward, and after the water flow is sprayed out from the water outlet end, it can also generate a driving force, and together with the driving assembly, drives the moving wheel 8 to move along the inner wall of the pipe.

[0088] As a preferred solution, a direction-changing component is further included. When the pipeline cleaning device of this embodiment is used for cleaning a pipeline with one end closed, the direction-changing component can drive the water spray pipe 2 to rotate by a certain angle after the cleaning device reaches the end point and hits the inner wall of the end of the pipeline. Further preferably, the direction-changing component can be set to drive the water spray pipe 2 to rotate by 180° after hitting the inner wall of the end of the pipeline.

[0089] Specifically, Figure 2-3 and Figure 9-12 As shown, the direction-changing assembly includes a reversing rod 10, a main reversing gear 13 and a slave reversing gear 14; wherein the reversing rod 10 is installed on the top of the housing 1, can move back and forth along the axial direction, and has a part extending outward from the top of the housing 1, and a part located inwardly inside the housing 1; the main reversing gear 13 is rotatably installed on the top of the housing 1, and when the reversing rod 10 moves along the axial direction, the main reversing gear 13 can be driven to rotate through a linkage structure; the slave reversing gear 14 is fixedly sleeved and installed on the part of the water spray pipe 2 located inside the housing 1, and is meshed and connected with the main reversing gear 13; when the reversing rod 10 moves up and down to drive the main reversing gear 13 to rotate, the slave reversing gear 14 can be driven by the main reversing gear 13, and then drive the water spray pipe 2 to rotate, so as to adjust the direction of the water outlet end of the water spray pipe 2 located outside the housing 1.

[0090] When the reversing rod 10 hits the inner wall of the pipe end, the impact force of the inner wall of the pipe will drive the reversing rod 10 to move toward the inside of the shell 1. The movement of the reversing rod 10 drives the main reversing gear 13 to rotate through the linkage structure. The main reversing gear 13 drives the slave reversing gear 14 meshing with it to rotate. The slave reversing gear 14 is fixedly connected to the water spray pipe 2. The rotation of the slave reversing gear 14 drives the water spray pipe 2 to turn, so that the direction of the water outlet end of the water spray pipe 2 located outside the shell 1 can be adjusted, thereby changing the direction of action of the water spray pipe driving force; after the direction of the water spray pipe driving force changes, the rotation of the shell 1 is reversed, and then the moving wheel 8 is driven to roll in the opposite direction through the driving component.

[0091] like Figure 8 and 9 As shown, the linkage structure includes an axial slide 100, a first stopper 11, a rotary slide 101 and a second stopper 12; wherein the axial slide 100 is provided on the outer wall of the reversing rod 10, the first stopper 11 is fixedly arranged on the housing 1, and has a first slide post 111 that can extend into the axial slide 100 and slide with the axial slide 100; the rotary slide 101 is provided on the outer wall of the reversing rod 10, and is opposite to the axial slide 100 in front and back positions and is not connected to each other, the second stopper 12 is fixedly arranged on the main reversing gear 13, and has a second slide post 12 that can extend into the rotary slide 101 and slide with the rotary slide 101. When the reversing rod 10 moves axially, the first slide post 111 slides in the axial slide 100 to prevent the reversing rod 10 from rotating, and the second slide post 121 slides in the rotary slide 101 to drive the main reversing gear 13 to rotate.

[0092] The pipe cleaning device based on water spraying power of this embodiment has the following working process: when in use, one end of the main pipe 4 is connected to a water pipe, and water with a certain pressure enters the water storage space 33 of the water inlet tank 3 from the main pipe 4, and is further sprayed out through the water outlet end of the water spraying pipe assembly through the water outlet; when the water flow is sprayed out from the water outlet end of the water spraying pipe assembly, the reaction force of the water spraying drives the housing 1 to rotate, and then drives the water spraying pipe assembly to rotate, so as to clean the inner wall of the pipe;

[0093] The rotation of the outer shell 1 drives the inner gear cylinder 5 to rotate, and the inner gear cylinder 5 drives the transmission gear 62 of the transmission member 61 to rotate through the meshing teeth on the inner wall, thereby driving the transmission cable 7 to rotate, and the main transmission tooth 71 at the other end of the transmission cable 7 meshes with the slave transmission tooth 72 on the moving wheel 8, thereby driving the moving wheel 8 to rotate, and then driving the pipeline cleaning device of this embodiment to automatically move along the inner wall of the pipeline;

[0094] When the reversing rod 10 hits the inner wall of the pipe end, the force of hitting the inner wall of the pipe end drives the reversing rod 10 to move toward the inside of the shell 1. The movement of the reversing rod 10 drives the main reversing gear 13 to rotate through the linkage structure. The main reversing gear 13 drives the slave reversing gear 14 meshing with it to rotate. The slave reversing gear 14 is fixedly connected to the water spray pipe 2. The rotation of the slave reversing gear 14 drives the water spray pipe 2 to turn, so that the direction of the water outlet end of the water spray pipe 2 located outside the shell 1 can be adjusted, thereby changing the direction of action of the water spray pipe driving force. The water spray driving force after changing direction drives the shell 1 to reverse, and then drives the moving wheel 8 to reverse through the internal gear cylinder 5, the transmission member 61, the transmission cable 7, etc., so that the pipeline cleaning device of this embodiment can return from the pipe end at the tail end to the pipe end at the initial position under the action of the force with changed direction after hitting the inner wall of the pipe end.

[0095] Obviously, the above embodiments are only examples for clear explanation, and are not limitations on the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description, and the obvious changes or modifications derived therefrom are still within the protection scope of the present innovative technical solution.
