Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a cleaning device for water conservancy pipelines. Background Art

[0002] Water conservancy pipes are important facilities for transporting water resources in water conservancy projects. They can be classified by pipe materials into metal pipes, plastic pipes, composite pipes and cement pipes. When metal pipes are used in water conservancy projects, a layer of anti-corrosion coating will be coated on their inner walls. The purpose is to extend the service life of the pipes and reduce friction damage and fluid resistance. Cleaning of water conservancy pipes is an important part of ensuring the normal operation of water conservancy projects and extending the service life of pipes. Common cleaning methods include flushing the inner wall of the water conservancy pipe with high-pressure water and cleaning the inner wall of the water conservancy pipe with a brush.

[0003] A Chinese patent document with announcement number CN114798619B discloses a construction water conservancy pipeline cleaning device, including a mounting frame, on which a cleaning mechanism, a spraying assembly and a guide assembly are provided. A cleaning brush is used in combination with a cleaning liquid to clean the sludge and oil stains on the inner wall of the sewage pipe. A cleaning brush is used in combination with clean water to perform a secondary cleaning on the inner wall of the sewage pipe, thereby achieving a thorough cleaning of the dirt on the inner wall of the sewage pipe. An electric wheel and a guide wheel are used to fit closely with the inner wall of the sewage pipe, and the guide wheel adopts an anti-skid wheel to achieve anti-skid during the vertical upward movement. This device can overcome the disadvantage of wasting a lot of water resources by using a large amount of high-pressure and high-speed flowing water to clean the sludge, oil stains and other impurities deposited in the sewage pipe.

[0004] However, the above patent document still has the following shortcomings: during the use of water conservancy pipes, some microorganisms are prone to form large protruding impurities on the inner wall of the pipes, which are difficult to remove by high-pressure water flushing and cleaning brushes. It is easy to cause solid impurities in the water to become entangled with the large protruding impurities when the water conservancy pipes continue to be used, thereby causing blockage of the pipes. Summary of the invention

[0005] The present invention provides a cleaning device for water conservancy pipelines, aiming to solve the problem in the related art that some microorganisms are prone to form large protruding impurities on the inner wall of the pipeline, which are difficult to remove by high-pressure water flushing and cleaning brushes, and are likely to cause entanglement between solid impurities in the water and the large protruding impurities when the water conservancy pipeline continues to be used, thereby causing pipeline blockage.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 9 As shown, the cleaning device for water conservancy pipelines of the present invention comprises a traveling mechanism 1 and a cleaning mechanism 2. The cleaning mechanism 2 is connected to the traveling mechanism 1. The traveling mechanism 1 can drive the cleaning mechanism 2 to enter the water conservancy pipeline after cleaning. The cleaning mechanism 2 can shear the protruding impurities that have not been cleaned in the water conservancy pipeline to avoid entanglement between solid impurities in the water and large protruding impurities when the water conservancy pipeline continues to be used.

[0031] like Figures 1 to 5 As shown, the walking mechanism 1 includes a shell 11, an end cover 12, a telescopic leg 13, an elastic part 14, an electric wheel 15, a telescopic part 16, a moving frame 17, a driving wheel 18, a connecting arm 19, an induction member 110 and an elastic part 2 111, the end cover 12 is connected to the left end of the shell 11, the telescopic leg 13 is inserted into the outer side of the shell 11, the elastic part 14 is connected between the shell 11 and the telescopic leg 13, the electric wheel 15 is connected to the end of the telescopic leg 13 away from the shell 11, and the telescopic leg 13 is provided in two groups, each group of telescopic legs 1 The number of 3 is set to three, the three telescopic legs 13 in the same group are arranged in a ring, the end of the telescopic leg 13 extending into the shell 11 is provided with an inclined surface 131, the telescopic part 16 is connected to the end cover 12, the telescopic part 16 is a cylinder, the mobile frame 17 is connected to the telescopic end of the telescopic part 16, the driving wheel 18 is rotatably connected to the mobile frame 17, the driving wheels 18 are set to two groups, the number of driving wheels 18 in each group is set to three, and the three driving wheels 18 in the same group are arranged correspondingly to the inclined surfaces 131 on the three telescopic legs 13 in the same group.

[0032] The contraction of the telescopic end of the telescopic part 16 can drive the moving frame 17 to move, and the two sets of pushing wheels 18 on the moving frame 17 respectively push the two sets of telescopic legs 13, so that each telescopic leg 13 moves in a direction away from the axis of the shell 11 until the electric wheel 15 contacts the inner wall of the water conservancy pipe. At the same time, the telescopic legs 13 themselves can be retracted so that the electric wheel 15 can pass over the impurities on the inner wall of the water conservancy pipe, so as to avoid the electric wheel 15 being blocked by impurities and causing the walking mechanism 1 to be unable to operate normally. Starting the electric wheel 15 can enable the walking mechanism 1 to drive the cleaning mechanism 2 to move in the water conservancy pipe.

[0033] A mounting port is provided at the right end of the shell 11, and the connecting arm 19 is inserted into the mounting port at the right end of the shell 11. The sensing piece 110 is connected in the mounting port, and the sensing piece 110 is in contact with the connecting arm 19. The sensing piece 110 is a pressure sensor. The elastic part 111 is connected between the connecting arm 19 and the shell 11. The cleaning mechanism 2 is connected to the connecting arm 19 and the shell 11. When the walking mechanism 1 drives the cleaning mechanism 2 to move in the water conservancy pipeline, the cleaning mechanism 2 is blocked by large protruding impurities, so that the connecting arm 19 squeezes the sensing piece 110. At this time, the sensing piece 110 detects the pressure. After the pressure reaches the set value, the electric wheel 15 is closed, and the cleaning mechanism 2 is started to shear and clean the large protruding impurities on the inner wall of the water conservancy pipeline.

[0034] like Figure 1 , Figure 4 , Figures 6 to 9As shown, the cleaning mechanism 2 includes a support ring 21, a driving member 1 22, a driving member 23 and a cutter member 24. The support ring 21 is connected to the connecting arm 19, the driving member 1 22 is connected to the right end of the shell 11, the driving member 23 is connected to the driving member 1 22, and the cutter member 24 is connected to the driving member 2 23. The support ring 21 can contact the left side of the large protruding impurities, thereby providing support for the subsequent shearing of the large protruding impurities to avoid the anti-corrosion coating on the inner wall of the water conservancy pipeline being damaged due to the thrust of the cutting member 24 when the cutting member 24 shears the large protruding impurities. The driving member 23 can drive the cutting member 24 to expand into a ring shape to facilitate the subsequent shearing of the large protruding impurities. The driving member 1 22 can drive the driving member 2 23 and the cutter member 24 to approach the support ring 21, so that the large protruding impurities are sheared and cleaned by the cutting member 24.

[0035] Continue to refer Figure 1 , Figure 4 , Figures 6 to 9 As shown, the outer diameter of the support ring 21 is slightly smaller than the inner diameter of the water conservancy pipe, so as to facilitate the placement of the support ring 21 in the water conservancy pipe. The support ring 21 includes a support part 1 211, a support part 212 and a telescopic part 213. The support part 1 211 is connected to the connecting arm 19. The support part 1 211 is provided with an opening, and the opening of the support part 1 211 faces downward. The telescopic part 213 is connected to the support part 1 211. The telescopic part 213 is an electric telescopic rod. The support part 212 is connected to the telescopic end of the telescopic part 213, and the support part 212 is located in the opening of the support part 1 211.

[0036] After being sheared, the large protruding impurities fall to the inner bottom wall of the water conservancy pipe. Starting the telescopic part 213 can drive the supporting part 212 to move upward, so that when the walking mechanism 1 drives the cleaning mechanism 2 to continue to move, the supporting ring 21 can pass over the cleaned large protruding impurities.

[0037] Continue to refer Figure 1 , Figure 4 , Figures 6 to 9 As shown, the driving member 22 includes a mounting seat 221, a movable sleeve 222 and a telescopic part 3 223. The mounting seat 221 is connected to the right end of the shell 11, the movable sleeve 222 is sleeved on the outside of the mounting seat 221, the telescopic part 3 223 is connected to the mounting seat 221, the telescopic part 3 223 is a cylinder, the telescopic end of the telescopic part 3 223 is connected to the movable sleeve 222, and the driving member 23 is connected to the movable sleeve 222. Starting the telescopic part 3 223 can drive the movable sleeve 222 to move left and right, thereby driving the driving member 23 and the cutting member 24 to move closer to or away from the support ring 21.

[0038] Continue to refer Figure 1 , Figure 4 , Figures 6 to 9As shown, the driving member 23 includes a connecting structure 1, a connecting structure 2, a pushing portion 237 and a driving source 238. The connecting structure 1 includes a guide rail 231, a connecting portion 232 and a fixed column 233. The guide rail 231 is connected to the outer side of the movable sleeve 222. The connecting portion 232 is slidably connected to the guide rail 231. The fixed column 233 is connected to the connecting portion 232. The connecting structure 2 includes a guide rail 234, a connecting portion 235 and a fixed column 236. The guide rail 234 is connected to the outer side of the movable sleeve 222. On the outside of the movable sleeve 222, the connecting part 235 is slidably connected to the guide rail 234, the fixed column 236 is connected to the connecting part 235, the connecting structure 1 and the connecting structure 2 are both set to three groups, the three groups of connecting structures 1 and the three groups of connecting structures 2 are arranged alternately in a ring shape, the pushing part 237 is rotatably connected to the right end of the movable sleeve 222, the driving source 238 is connected to the inner right end of the movable sleeve 222, the driving source 238 is a motor, and the output shaft of the driving source 238 is connected to the pushing part 237.

[0039] The pushing portion 237 is provided with a pushing groove 1 2371 and a pushing groove 2372. The pushing groove 1 2371 and the pushing groove 2372 are both provided in three numbers. The three pushing grooves 1 2371 and the three pushing grooves 2372 are alternately arranged in a ring shape. The three fixing posts 1 233 are respectively slidably connected in the three pushing grooves 1 2371. When the pushing portion 237 rotates, the three fixing posts 1 233 can be simultaneously pushed by the three pushing grooves 1 2371, so that the three connecting portions 1 232 are simultaneously moved away from or close to each other. The pushing portion 237 moves in the direction close to the center of the circle. The three fixed columns 236 are respectively slidably connected in the three pushing grooves 2372. The pushing groove 2372 includes an arc segment 1 23721 and an arc segment 23722. The arc segment 23722 is close to the edge of the pushing portion 237, and the arc segment 23722 and the center of the circle of the pushing portion 237 are located on the same axis. When the fixed column 236 is in the arc segment 23722, the rotation of the pushing portion 237 will not drive the three fixed columns 236 to move.

[0040] Continue to refer Figure 1 , Figure 4 , Figures 6 to 9 As shown, the cutter member 24 includes a cutter 1 241 and a cutter 242. The cutter 1 241 and the cutter 2 242 are each provided in three numbers. The three cutters 241 are respectively connected to the three connecting parts 1 232, the three cutters 242 are respectively connected to the three connecting parts 235, and the three cutters 242 are located on the inner side of the three cutters 1 241.

[0041] Before the support ring 21 comes into contact with the large protruding impurity, the fixing column 1 233 is located at one end of the pushing groove 1 2371 close to the center of the pushing portion 237, and the fixing column 236 is located at one end of the arc segment 1 23721 close to the center of the pushing portion 237. After the support ring 21 comes into contact with the large protruding impurity, the driving source 238 is started to drive the pushing portion 237 to rotate, and the three connecting portions 1 232 are simultaneously pushed toward the direction away from the pushing portion 237 through the three pushing grooves 1 2371. The three pushing grooves 2372 simultaneously push the three connecting parts 235 to move in a direction away from the pushing part 237. After the fixing column 236 on the connecting part 235 enters the arc segment 23722, the connecting part 235 stops moving until the cutting pieces 24 of the three cutting knives 1 241 and the three cutting knives 242 are in a ring shape, and the driving piece 1 22 drives the ring-shaped cutting piece 24 to approach the supporting ring 21, thereby shearing and cleaning the large protruding impurities on the inner wall of the water conservancy pipe.

[0042] When the cutting blade 24 is driven to reset after shearing is completed, the driving source 238 drives the pushing part 237 to rotate in the opposite direction, so that the connecting part 235 remains stationary under the action of the arc segment 23722, and the connecting part 1 232 moves toward the direction close to the center of the pushing part 237 under the push of the pushing groove 1 2371. After the fixing column 236 on the connecting part 235 enters the arc segment 1 23721, the fixing column 236 is pushed by the arc segment 1 23721 to make the connecting part 235 move toward the direction close to the center of the pushing part 237, thereby realizing the resetting of the cutting blade 24 to ensure that large protruding impurities can enter between the cutting blade 24 and the support ring 21.

[0043] In other embodiments, the three cutters 1 241 and the three cutters 2 242 can also be controlled by two groups of cylinders to expand the three cutters 1 241 and the three cutters 2 242 outward, and make the cutter member 24 in a ring shape, and can drive the three cutters 1 241 and the three cutters 2 242 to retract and reset.

[0044] Working principle:

[0045] Put the walking mechanism 1 and the cleaning mechanism 2 into the water conservancy pipeline from the left end of the water conservancy pipeline, and the cleaning mechanism 2 is located on the right side of the walking mechanism 1, and at the same time, make the opening of the support ring 21 face downward, start the telescopic part 16, drive the moving frame 17 to move, and use the two sets of pushing wheels 18 on the moving frame 17 to push the two sets of telescopic legs 13 respectively, so that each telescopic leg 13 moves in a direction away from the axis of the shell 11 until the electric wheel 15 contacts the inner wall of the water conservancy pipeline.

[0046] The electric wheel 15 is started so that the traveling mechanism 1 drives the cleaning mechanism 2 to move rightward in the water conservancy pipeline.

[0047] After the support ring 21 contacts the large protruding impurities, it is blocked by the large protruding impurities, and the electric wheel 15 continues to run, so that the connecting arm 19 squeezes the sensing element 110. At this time, the sensing element 110 detects the pressure, and when the pressure reaches the set value, the electric wheel 15 is closed.

[0048] The driving source 238 is started to drive the pushing part 237 to rotate, and the three connecting parts 232 are pushed simultaneously to move in a direction away from the pushing part 237 through the three pushing grooves 1 2371, and the three connecting parts 235 are pushed simultaneously to move in a direction away from the pushing part 237 through the three pushing grooves 2372. After the fixing column 236 on the connecting part 235 enters the arc segment 2 23722, the connecting part 235 stops moving until the cutting piece 24 of the three cutting knives 1 241 and the three cutting knives 242 are in a ring shape.

[0049] The telescopic part 3 223 is started to drive the movable sleeve 222 to move leftward, so that the annular cutter piece 24 is close to the supporting ring 21, and the large protruding impurities are sheared and cleaned, and the cleaned large protruding impurities fall on the inner bottom wall of the water conservancy pipeline.

[0050] The telescopic part 213 is started to drive the supporting part 212 to move upward, and the walking mechanism 1 drives the cleaning mechanism 2 to continue to move to the right. After the supporting part 212 passes over the large protruding impurities under cleaning, the telescopic part 213 is started to drive the supporting part 212 to move downward and reset.
