Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to an underground sewage pipeline cleaning device. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Since power plants use domestic waste to generate electricity, and domestic waste contains a large amount of water and soluble organic matter, during the stacking and treatment process, the waste will flow out with the water to form garbage leachate. In order to avoid polluting the environment, it is generally collected and discharged through underground sewage pipes to facilitate subsequent harmless treatment.

[0004] During the long-term transportation of garbage leachate in underground sewage pipes, the sediment in the sewage will gradually adhere and accumulate in the pipes. If they are not cleaned for a long time, the pipes will be blocked. There are generally two ways to clean underground sewage pipes. One is to use a high-pressure water gun to flush the inner wall of the pipe. This method consumes a lot of water when cleaning the pipe and cannot meet today's environmental protection and green needs. The other is to use a mechanical trolley to enter the sewage pipe, and use the scraper or chain carried by the trolley to scrape off the adhesions on the inner wall of the pipe during rotation. However, in actual use, the scraper will encounter greater resistance when rotating and scraping, and the cleaning effect is poor. The chain rotates and hits the pipe, which will cause damage to the inner wall of the pipe, affecting the service life of the pipe. Summary of the invention

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-6 The present invention discloses an underground sewage pipe cleaning device, comprising:

[0037] At least two traveling mechanisms 1, used for traveling inside the pipeline and capable of being fixed inside the pipeline;

[0038] A connecting mechanism 2, used for connecting two adjacent walking mechanisms 1;

[0039] The cleaning rope 3 is arranged between two adjacent walking mechanisms 1 and can move toward and away from one side of the pipe wall;

[0040] The driving mechanism 4 includes a rotating assembly 41 for driving the cleaning rope 3 to rotate, a telescopic assembly 42 for driving the cleaning rope 3 to move toward and away from the pipe wall, and a reciprocating assembly 43 for driving the cleaning rope 3 to reciprocate along the length direction of the pipe.

[0041] According to the present invention, the cleaning rope 3 is driven to move inside the pipe by the traveling mechanism 1. When it moves to the desired position, the two traveling mechanisms 1 are fixed inside the pipe and the cleaning rope 3 is tightened. Then, the telescopic component 42 is used to push the cleaning rope 3 close to the pipe wall that needs to be cleaned. Then, with the cooperation of the rotating component 41 and the reciprocating motion component 43, the cleaning rope 3 is reciprocated and sawed during the process of rotating close to the pipe wall, so that the dirt adhered to the pipe wall is cut and scraped off, thereby reducing the water consumption when cleaning the pipe. At the same time, due to the sawing method, the dirt adhered to the pipe wall can be scraped off as quickly as possible while reducing the damage to the pipe wall. Compared with the current method of hitting the pipe by chain rotation, the damage to the pipe is less.

[0042] It should be noted that the cleaning rope 3 is preferably a metal wire rope, which can reduce the wear of the cleaning rope 3 by dirt during the cleaning process.

[0043] In one embodiment, the traveling mechanism 1 includes a wheeled traveling trolley 11, on which a supporting assembly 12 capable of telescopically supporting the pipe wall is provided;

[0044] The supporting assembly 12 includes a first telescopic component 121 disposed on the top of the wheeled walking trolley 11 and a supporting block 122 driven by the first telescopic component 121 to move toward and away from the pipe wall.

[0045] Such a design enables the wheeled trolley 11 to move to the desired position, and the top support block 122 is driven to rise by the first telescopic component 121, and abuts against the pipe wall, thereby cooperating with the wheel of the wheeled trolley 11 to complete the positioning of the wheeled trolley 11. Since the top support block 122 can be raised and lowered, the walking mechanism 1 can be fixed inside pipes of different diameters, and has a wider applicability.

[0046] The specific working process is to first use the wheeled walking trolley 11 to advance to the set point in the pipeline, then make the top support assembly 12 on one of the wheeled walking trolleys 11 abut against the pipe wall, and then make the remaining wheeled walking trolleys 11 continue to move along the pipeline. After tightening the cleaning rope 3, the top support assembly 12 on the corresponding wheeled walking trolley 11 works again, so that the cleaning rope 3 can remain taut when cleaning dirt, ensuring the scraping effect of the dirt.

[0047] It should be noted that the power supply method and control method of the wheeled walking vehicle 11 are both existing technologies and will not be described in detail here.

[0048] In one embodiment, an image acquisition mechanism 5 for acquiring images inside the pipeline is disposed at the bottom of the top support block 122. The image acquisition mechanism 5 is composed of a camera component for acquiring and transmitting images and a fill light component for filling light for the camera component.

[0049] This design enables maintenance personnel to observe the internal conditions of the pipeline through the image acquisition mechanism 5 at the pipeline maintenance port, and can achieve remote control, further improving the scope of use.

[0050] It should be noted that the camera assembly and the fill light assembly are both existing technologies and will not be described in detail here.

[0051] In one embodiment, the rotating assembly 41 includes a plurality of rotating disks 411 rotatably disposed on the wheeled walking trolley 11, each cleaning rope 3 corresponds to two rotating disks 411, and two adjacent rotating disks 411 are connected by a connecting mechanism 2 to rotate synchronously, and the cleaning rope 3 is connected to the adjacent rotating disk 411 and rotates with the rotating disk 411;

[0052] The rotating assembly 41 also includes a rotating motor (not shown) disposed inside one of the two adjacent wheeled walking carts 11 , and the output end of the rotating motor is connected to one of the corresponding turntables 411 of each cleaning rope 3 to drive the corresponding turntable 411 to rotate.

[0053] Such a design enables the turntable 411 to synchronously drive the two ends of the cleaning rope 3 to rotate together under the connection of the connection mechanism 2, thereby ensuring that the cleaning rope 3 can maintain a set posture during operation.

[0054] In one embodiment, the connection mechanism 2 includes at least two connection rods, two adjacent connection rods are rotatably connected, and the first and last connection rods are fixedly connected to the corresponding rotating disk 411 respectively.

[0055] Such a design ensures that the multiple wheeled walking vehicles 11 do not need to maintain a working state when entering the pipeline, and can be bent according to the shape of the pipeline maintenance opening, thereby being able to adapt to a narrower working environment.

[0056] In one embodiment, the cleaning rope 3 is laid in a ring shape between two adjacent walking mechanisms 1, and both ends of the cleaning rope 3 are connected to the reciprocating motion component 43, and is driven by the reciprocating motion component 43 to reciprocate along the laying track of the cleaning rope 3;

[0057] The telescopic assembly 42 includes a plurality of positioning blocks 422 for keeping the cleaning rope 3 in a ring shape and being clamped with the cleaning rope 3. Each positioning block 422 is provided with a second telescopic component 421 for pushing the positioning block 422 to move toward and away from one side of the pipe wall. The second telescopic component 421 is fixedly arranged on the adjacent turntable 411.

[0058] This design allows the cleaning rope 3 to contact both sides of the pipe wall at the same time, increasing the cleaning efficiency, and by guiding the laying direction of the cleaning rope 3 through the positioning block 422, it can ensure that the shape of the cleaning rope 3 remains roughly unchanged when it is in a non-tensioned state, and can quickly restore the set shape after subsequent tensioning.

[0059] It should be noted that a through hole is provided on the positioning block 422 for the cleaning rope 3 to pass through, so as to facilitate the replacement of the cleaning rope 3 after the cleaning rope 3 is damaged.

[0060] In one embodiment, the reciprocating motion component 43 includes a speed-increasing gear set 431 rotatably arranged on the other of two adjacent wheeled walking carts 11, and an internal tooth groove meshing with the speed-increasing gear set 431 is provided in the turntable 411 of the adjacent speed-increasing gear set 431, and an eccentric wheel 432 driven by the speed-increasing gear set 431 is provided at the output end of the speed-increasing gear set 431, and the outer sleeve of the eccentric wheel 432 is provided with a rectangular frame 433 that can be rotated by the eccentric wheel 432 and reciprocate in the corresponding turntable 411, and the reciprocating motion component 43 also includes a fixed clamping component for fixing the two ends of the cleaning rope 3 to the rectangular frame 433.

[0061] In this design, the power of the rotating disk 411 drives the speed-increasing gear set 431 to rotate, so that the eccentric wheel 432 installed on the speed-increasing gear set 431 rotates. During the rotation of the eccentric wheel 432, the rectangular frame 433 is pushed along the Figure 4 The cleaning rope 3 shown reciprocates in the width direction, so that the cleaning rope 3 fixed on the rectangular frame 433 by the fixed clamping component moves back and forth to achieve a cutting effect. At the same time, due to the speed-increasing effect of the speed-increasing gear set 431, when the turntable 411 is at a slower rotation speed, it can also ensure that the cleaning rope 3 can move back and forth faster, thereby ensuring that the rotation speed of the turntable 411 and the back and forth cutting speed of the cleaning rope 3 can meet the requirements during operation.

[0062] In one embodiment, the fixed clamping component includes a locking seat 434 fixedly connected to the rectangular frame 433 and one end of which is inserted into an adjacent connecting rod. The locking seat 434 is located at one end of the connecting rod and is provided with a locking pressure block 435 that can move axially along the connecting rod. The connecting rod is externally threaded with an adjusting screw sleeve 436. The connecting rod is also provided with a push plate 437 located at one end of the locking pressure block 435 away from the locking seat 434 and can be pushed by the adjusting screw sleeve 436 to move toward the side close to the locking seat 434. The locking seat 434 is provided with a compression spring 438 for pushing the locking pressure block 435 to move into the connecting rod. When the compression spring 438 is in an uncompressed state, a slot is provided between the locking seat 434 and the locking pressure block 435 for the cleaning rope 3 to pass through at both ends.

[0063] This design allows maintenance personnel to directly rotate the adjusting screw sleeve 436 from the outside to move the adjusting screw sleeve 436 away from the compression spring 438, thereby releasing the pressure on the push plate 437 and allowing the compression spring 438 to push the locking pressure block 435 away from the locking seat 434, thereby allowing the cleaning rope 3 to be quickly pulled out and replaced. Conversely, after inserting the two ends of the cleaning rope 3 into the slot, the adjusting screw sleeve 436 can be rotated in the opposite direction to push the push plate 437 to squeeze the locking pressure block 435, so that the locking pressure block 435 presses the cleaning rope 3, thereby allowing the cleaning rope 3 to be driven by the locking seat 434 to move together, and because the push plate 437 and the locking pressure block 435 are not fixed, the squeezing force on the locking pressure block 435 can be maintained without affecting the locking pressure block 435 from moving together with the locking seat 434.

[0064] In a specific implementation, the first telescopic component 121 and the second telescopic component 421 can be hydraulic telescopic components, pneumatic telescopic components, and electric telescopic components in the prior art.

[0065] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0067] In addition, "plurality" means two or more.
