Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline cleaning devices, in particular to a pipeline cleaning device based on water jet power. BACKGROUND

[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 deposits and dirt inside the pipeline, improve the flowability of the pipeline, reduce the occurrence of pipeline blockage, and ensure the normal operation of the pipeline for a long time. Regular cleaning of the pipeline can also reduce the occurrence of pipeline corrosion and wear, prolong the service life of the pipeline, and reduce the cost of maintenance and replacement of the pipeline.

[0003] The existing pipeline cleaning devices are basically driven by electricity to clean the pipeline. Chinese patent document CN115193832A discloses a pipeline cleaning device, which comprises a rotating body, a support body and a driving body for abutting against the pipe wall and driving the rotating body and the support body to slide along the pipeline, which are arranged in sequence. The support body is in the form of a cylinder, and a rotating motor is arranged on the support body to drive the rotating body to rotate. A plurality of flushing nozzles for flushing the pipe wall are arranged on the rotating body in the circumferential direction thereof. A main pipe is rotatably connected to the end face of the rotating body away from the rotating motor. A plurality of arc-shaped support blocks are uniformly arranged on the support body in the circumferential direction thereof. A plurality of pulleys for abutting against the pipe wall are arranged on the support blocks. When cleaning the pipeline, first place the device as a whole in the pipeline to be cleaned and make the pulleys arranged on the support blocks abut against the pipe wall. Then use an external pressurized device to input pressurized water into the rotating body through the main pipe and output it through the flushing nozzles to flush the pipe wall. Then start the rotating motor to make the rotating body rotate. Later, use the driving body to drive the device as a whole to slide along the pipeline to complete the cleaning of the pipeline.

[0004] The technical solution in the above patent document drives the rotating body to rotate by the rotating motor, and drives the whole device to slide along the pipeline by the driving device.

[0087] As shown in Figures 7-8As shown, the water spraying pipe assembly in the embodiment includes a water spraying pipe 2 and a rotary joint; wherein the water spraying pipe 2 is rotatably installed on the shell 1, one end of which extends out of the shell 1 and the other end of which is located inside the shell 1; the water outlet end of the water spraying pipe 2 extending out of the shell 1 is directed in a rearward oblique direction; the rotary joint 21 has a rotatable end 23 and a fixed end 24, the rotatable end 23 is rotatably and sealingly connected with the other end of the water spraying pipe 2, and the fixed end 24 is connected with the water outlet of the water inlet chamber 3 through a connecting pipe 22. The water outlet end of the water spraying pipe 2 extending out of the shell 1 is directed in a rearward oblique direction, so that the water flow sprayed from the water outlet end can also generate a driving force, which, together with the driving assembly, drives the moving wheel 8 to move along the inner wall of the pipeline.

[0088] As a preferred solution, a direction changing assembly is further included, which can drive the water spraying pipe 2 to rotate by a certain angle after the pipeline cleaning device of the embodiment is used to clean a pipeline with one end closed and the cleaning device hits the inner wall of the end of the pipeline.

[0089] Specifically, as shown in Figures 2-3 and Figures 9-12 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 shell 1 and can move back and forth along the axial direction, has a part extending out of the top of the shell 1 and a part located inside the shell 1; the main reversing gear 13 is rotatably installed on the top of the shell 1 and can drive the main reversing gear 13 to rotate through a linkage structure when the reversing rod 10 moves along the axial direction; the slave reversing gear 14 is fixedly installed on the part of the water spraying pipe 2 located inside the shell 1 and is in meshing connection 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 in turn, drive the water spraying pipe 2 to rotate, so as to adjust the direction of the water outlet end of the water spraying pipe 2 located outside the shell 1.

[0090] When the reversing rod 10 hits the inner wall of the end of the pipeline, the impact force of hitting the inner wall of the pipeline drives the reversing rod 10 to move into 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 in meshing connection therewith to rotate, the slave reversing gear 14 is fixedly connected with the water spraying pipe 2, and the rotation of the slave reversing gear 14 drives the water spraying pipe 2 to turn, so as to adjust the direction of the water outlet end of the water spraying pipe 2 located outside the shell 1, and in turn, change the direction of the driving force of the water spraying pipe; after the direction of the driving force of the water spraying pipe is changed, the rotation of the shell 1 is reversed, and in turn, the moving wheel 8 is driven by the driving assembly to roll reversely.

[0091] As Figure 8 and 9 shown, the linkage structure includes an axial slot 100, a first limiting piece 11, a spiral slot 101 and a second limiting piece 12; wherein the axial slot 100 is opened on the outer wall of the reversing rod 10, the first limiting piece 11 is fixedly arranged on the shell 1, and has a first sliding column 111 capable of extending into the inside of the axial slot 100 and slidingly matched with the axial slot 100; the spiral slot 101 is opened on the outer wall of the reversing rod 10, and is independent of the axial slot 100, the second limiting piece 12 is fixedly arranged on the main reversing gear 13, and has a second sliding column 121 capable of extending into the inside of the spiral slot 101 and slidingly matched with the spiral slot 101. When the reversing rod 10 moves along the axial direction, the first sliding column 111 slides in the axial slot 100 to prevent the reversing rod 10 from rotating, and the second sliding column 121 slides in the spiral slot 101 to drive the main reversing gear 13 to rotate.

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

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

[0094] When the reversing rod 10 hits the inner wall of the end portion of the pipeline, the force of hitting the inner wall of the end portion of the pipeline drives the reversing rod 10 to move into 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 connected therewith to rotate, the slave reversing gear 14 is fixedly connected with the water jet pipe 2, and the rotation of the slave reversing gear 14 drives the water jet pipe 2 to change direction, so as to adjust the orientation of the water outlet end of the water jet pipe 2 located outside the shell 1, and further change the direction of the water jet driving force, the water jet driving force after changing the direction drives the shell 1 to reverse, and further drives the moving wheel 8 to reverse through the inner tooth cylinder 5, the transmission member 61 and the transmission cable 7, so that the pipeline cleaning device of the embodiment can return from the end portion of the tail end of the pipeline to the end portion of the pipeline at the initial position under the action of the force after changing the direction.

[0095] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present technical solution.
