Description

Technical Field

[0001] The invention relates to the technical field of pipe cleaners, in particular to a municipal pipeline cleaning device. Background Art

[0002] Since the pipe cleaner is an efficient and widely used pipe cleaning tool, it is particularly suitable for cleaning long-distance and large-diameter pipes, such as sewage pipes, water pipes, etc. And the pipe cleaner can effectively remove sediments, sand, scale and other impurities in the pipe to keep the pipe unobstructed, so the pipe cleaner is often used in municipal pipeline cleaning.

[0003] As in the prior art, the patent with the patent authorization announcement number CN206951721U discloses a pipe cleaner, including: at least two segment parts and an elastic component, each segment part includes a shaft body and at least one leather cup sleeved on the shaft body; wherein the first shaft body of the first segment part is rotatably connected with the second shaft body of the second segment part, and the first segment part and the second segment part are any two adjacent segment parts of the at least two segment parts; an elastic component is sleeved at the connection between the first shaft body and the second shaft body, and the elastic component is used to keep the first shaft body and the second shaft body on the same axis in a straight pipeline. This type of pipe cleaner reduces the probability of the pipe cleaner getting stuck, and no additional operations are required to solve the problem of the pipe cleaner getting stuck, thereby improving work efficiency.

[0004] Although the pipe cleaner in the above patent can reduce the probability of the pipe cleaner getting stuck at the bend, the pipe cleaner still has certain defects; when the pipe cleaner is cleaning the pipeline, if there are too many impurities at the front end of the pipe cleaner, the pipe cleaner may be blocked and unable to move (for example, if there is a lot of scale in the water supply pipeline, the scale can easily accumulate at the bend of the water supply pipeline, which will cause the pipe cleaner to be stuck and unable to move). At this time, a common method is to increase the pressure so that the pipe cleaner can push the impurities to move, so that the pipe cleaner can continue to clean the pipeline. However, since the length of the pipeline to be cleaned is relatively long, it takes a long time to pressurize the pipe cleaner to move it, so the existing pipe cleaner needs to be improved. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a municipal pipeline cleaning device to solve the problems raised by the background technology, making it easier to solve the blockage problem of the pipe cleaner after it is blocked.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1 to 12 A municipal pipeline cleaning device comprises a first frame 1, a first leather cup 2 is fixedly connected to the outer side of the first frame 1, a second frame 3 is arranged on one side of the first frame 1, a second leather cup 4 is fixedly connected to the outer side of the second frame 3, a third frame 5 is arranged on the side of the second frame 3 away from the first frame 1, a third leather cup 6 is fixedly connected to the outer side of the third frame 5, a placement cavity 11 is opened inside the first frame 1 near one end of the second frame 3, a limiting piston 10 matching the placement cavity 11 is fixedly connected to one end of the second frame 3 near the first frame 1, a hydraulic cavity 7 is opened at one end of the second frame 3 away from the limiting piston 10, and the hydraulic cavity 7 is filled with Hydraulic medium, a hydraulic piston 8 is slidably connected to the end of the hydraulic chamber 7 away from the limit piston 10, the hydraulic piston 8 is hinged to the end of the third skeleton 5, and a symmetrically arranged receiving groove 12 is opened at the end of the limit piston 10 close to the hydraulic piston 8, and a plurality of support blocks 13 are slidably connected inside the receiving groove 12, and a clamping block 15 is fixedly connected to the end of the support block 13 away from the central axis of the limit piston 10, and a wedge-shaped groove 14 is opened at the end of the side of the support block 13 away from the clamping block 15, and a wedge-shaped insert rod 9 is fixedly connected to the end of the hydraulic piston 8 close to the limit piston 10, and the end of the wedge-shaped insert rod 9 passes through the second skeleton 3 and abuts against the wedge-shaped groove 14.

[0031] The municipal pipeline cleaning device of the present invention can be pressurized into the pipeline after the device is stuck inside the pipeline, so that the pressure in the hydraulic chamber 7 of the second frame 3 is less than the pressure in the pipeline, and the third frame 5 will slowly push the hydraulic piston 8 to move in the direction of the limit piston 10, and at the same time, the hydraulic piston 8 will drive the wedge-shaped rod 9 to move synchronously, so that the wedge-shaped rod 9 is gradually inserted into the wedge-shaped groove 14 of the support block 13. After the pressure in the pipeline reaches a certain limit, the wedge-shaped rod 9 will be completely inserted into the wedge-shaped groove 14, so that the support block 13 and the card block 15 return to the receiving groove 12. At the moment when the support block 13 and the card block 15 return to the receiving groove 12, the second frame 3 and the third frame 5 will be moved to the direction of the limit piston 10. A distance between the skeletons 1 will lose support restriction. Under the strong pressure in the pipeline, the second skeleton 3 and the third skeleton 5 will move quickly toward the first skeleton 1 together, so that the second skeleton 3 and the third skeleton 5 will collide with the first skeleton 1 together, and the first skeleton 1 will transfer the force generated by the collision to the impurities at the front end of the first skeleton 1, thereby forming an impact force to loosen the impurities, thereby solving the blockage problem. Since multiple support blocks 13 and blocking blocks 15 are provided, if the blockage problem is still not solved, the pipeline will continue to be pressurized. After the pressure is increased to a certain level, the movement in the above steps will be triggered again, and a new impact force will be formed to make the impurities looser. Compared with the prior art, the traditional method is to continuously increase the pressure in the pipeline until it reaches a certain value to solve the blockage problem. However, since the pipeline is long, it takes a long time to solve the blockage problem. The municipal pipeline cleaning device in the present invention will generate an impact force as long as the pressure in the pipeline changes to a certain extent, thereby improving the efficiency of solving the blockage problem. In addition, the first leather cup 2, the second leather cup 4 and the third leather cup 6 in the present invention are existing mature products, so they will not be elaborated on here.

[0032] As a preferred technical solution of the present invention, a slider 19 is fixedly connected to the side of the support block 13 away from the wedge-shaped insertion rod 9, a slide groove 16 matching the slider 19 is opened on the side wall of the storage groove 12, a positioning column 17 is fixedly connected to the inside of the slide groove 16, the slider 19 is sleeved on the outside of the positioning column 17 and is slidably connected to the positioning column 17, an elastic member 18 is sleeved on the end of the positioning column 17 away from the blocking block 15, one end of the elastic member 18 is fixedly connected to the end of the slide groove 16, and the other end of the elastic member 18 is fixedly connected to the slider 19.

[0033] As a preferred technical solution of the present invention, a slot 20 is provided at the center position of the limit piston 10, and an active rack plate 23 is slidably connected inside the slot 20, and the active rack plate 23 is fixedly connected to the wedge-shaped insertion rod 9. Temporary storage grooves 21 are provided at the upper and lower ends of the limit piston 10, and a driven rack plate 25 is slidably connected inside the temporary storage groove 21. A transmission gear 24 is provided between the slot 20 and the temporary storage groove 21, and the transmission gear 24 is rotatably connected to the limit piston 10. The active rack plate 23 and the driven rack plate 25 are both meshed and connected with the transmission gear 24, and the end of the driven rack plate 25 is against the end of the placement cavity 11.

[0034] Specifically, after the jamming problem is solved, the device continues to move, and the pressure behind the third skeleton 5 will gradually decrease until it returns to a normal level. In the process of reducing the pressure, the hydraulic piston 8 will be pushed away, so that the second skeleton 3 and the third skeleton 5 are separated, so as to facilitate the impact when the jamming occurs next time. When the hydraulic piston 8 moves in the direction away from the second skeleton 3, the active rack plate 23 will drive the driven rack plate 25 to move through the transmission gear 24, so that the driven rack plate 25 moves in the direction away from the limit piston 10, thereby stretching the first skeleton 1 and the second skeleton 3 apart. At the same time, the wedge-shaped rod 9 will gradually disengage from the wedge-shaped groove 14, so that the support block 13 loses its restriction. Then, under the action of the elastic member 18, the block 15 will be pushed out by the support block 13, and then stuck between the first skeleton 1 and the second skeleton 3. In this way, the resetting work of the device can be completed, which is convenient for the next impact.

[0035] As a preferred technical solution of the present invention, a limiting groove 22 is provided on one side of the temporary storage groove 21 , and a limiting block 26 matching the limiting groove 22 is fixedly connected to one side of the driven rack plate 25 .

[0036] Specifically, the driven rack plate 25 is restricted by the limit block 26 so that the driven rack plate 25 is more stable when moving.

[0037] As a preferred technical solution of the present invention, the end of the limit block 26 is set in a trapezoidal shape, and the length of the limit block 26 is less than the length of the limit slot 22. The limit block 26 set in a trapezoidal shape has a better limiting effect, and the length of the limit block 26 is less than the length of the limit slot 22, so that the limit block 26 can be completely received in the limit slot 22, reducing the probability of damage to the limit block 26.

[0038] As a preferred technical solution of the present invention, the support blocks 13 are distributed at equal intervals, and the sum of the lengths of the plurality of support blocks 13 is equal to the distance between the first skeleton 1 and the second skeleton 3 .

[0039] Specifically, the plurality of support blocks 13 will be collected back into the receiving groove 12 in sequence, so that multiple collisions can be formed at a stable frequency within a certain period of time, thereby improving the efficiency of solving the blocking problem.

[0040] As a preferred technical solution of the present invention, the first frame 1 and the first leather cup 2, the second frame 3 and the second leather cup 4, and the third frame 5 and the third leather cup 6 are all fixedly connected by multiple bolts. Fixing the leather cups by bolts makes it easier to replace and maintain the leather cups.

[0041] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
