Description

Technical Field

[0002] At present, the cable laying pipelines of 10kV distribution network projects are often blocked by soil, sand, construction waste, etc., and the cable pipelines are not completely cleared after being blocked. There are sharp hard objects (such as stones, etc.) in the pipelines, which will cause scratches on the cables during cable laying. The construction site often uses municipal sprinkler trucks with high-pressure water guns to flush the pipelines. When the blockage is serious, it takes 1-2 days, which is time-consuming and labor-intensive, and the clearing effect and efficiency are low.

[0003] To this end, a Chinese patent with authorization announcement number CN118635219B discloses a cable pipe cleaning device, which realizes the intermittent advancement of forward disc one and forward disc two through the cooperation of a stop assembly and a threaded rod. When forward disc one moves forward, it pushes the silt and debris in front of it forward to the front of the dredging assembly. When forward disc two moves forward, it collects and gathers the silt and debris in front of forward disc two and transports them to the front of the dredging assembly through spiral blade one and spiral blade two.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 3 : A 10kV distribution network power pipeline pipe-clearing device, comprising a base 1, a push-pull device 2 and a cable rack 3; the push-pull device 2 comprises a slide 21, a clamping assembly 22 and a reciprocating propulsion assembly 23, the slide 21 is slidably mounted on the base 1, the clamping assembly 22 is arranged on the slide 21, and the base 1 is provided with a first station and a second station; the reciprocating propulsion assembly 23 is used to drive the slide 21 to reciprocate between the first station and the second station; a flexible cable 31 is wound around the cable rack 3, and a dredging head 32 for cleaning the pipeline is provided at the end of the flexible cable 31, the dredging head 32 comprises a traction head 321 and a push ring 322, the traction head 321 is connected to the flexible cable 31, and the push ring 322 is connected to the traction head 321; in the working state, when the slide 21 moves from the first station to the second station, the flexible cable 31 is clamped in the clamping assembly 22, and when the slide 21 moves from the second station to the first station, the clamping assembly 22 releases the flexible cable 31.

[0033] The present invention realizes the function of dredging the pipeline through the push-pull device 2, the flexible cable 31 and the dredging head 32, and solves the problem that the existing dredging equipment cannot effectively clean the pipeline with curvature. In the working state, the push-pull device 2 is started to push the flexible cable 31, and the flexible cable 31 pushes the dredging head 32 to move along the inner wall of the pipeline. The push ring 322 of the dredging head 32 pushes away the impurities on the inner wall of the pipeline, and the intermittent advancement of the flexible cable 31 is completed by clamping and loosening the clamping assembly 22. Compared with the traditional continuous advancement, the intermittent advancement can use the pause time after the dredging head 32 advances a certain distance to allow the dirt accumulated in front to have the opportunity to be dispersed or removed by the subsequent cleaning operation, thereby reducing the possibility of pipeline blockage. For example, when cleaning a cable pipeline containing a large amount of sludge, intermittent advancement combined with regular backwashing operations can effectively prevent sludge from accumulating in the pipeline to form a blockage, thereby efficiently cleaning the pipeline with a curved section. When cleaning the pipeline, the operator first connects the traction head 321 with the flexible cable 31, then passes the flexible cable 31 through the slide 21, and sends the dredging head 32 into the pipeline. Then, the slide 21 is pushed to move back and forth along the base 1 by the reciprocating propulsion component 23. When the slide 21 moves from the first station to the second station, the clamping component 22 clamps the flexible cable 31, and the slide 21 pushes the flexible cable 31 and the dredging head 32 deep into the pipeline; when the slide 21 moves from the second station to the first station, the clamping component 22 releases the flexible cable 31, controls the slide 21 to reset, and repeats the above actions to complete the intermittent propulsion of the dredging head 32.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The clamping assembly 22 includes two movable supports 221; the movable supports 221 are slidably arranged on the base 1, and a first elastic member 2211 is provided on the movable supports 221, and the first elastic member 2211 connects the two movable supports 221; each movable support 221 is provided with a clamping block 2212 and an oblique abutment block 2213; the base 1 is provided with an auxiliary control mechanism 4 for controlling the opening and closing of the movable supports 221, and the auxiliary control mechanism 4 includes two push rods 41, and each push rod 41 is provided with an extension rod 411, The push rod 41 is transmission connected to the reciprocating propulsion assembly 23; in the working state, when the push rod 41 moves from the first station to the second station, the extension rod 411 on the push rod 41 squeezes the oblique abutment block 2213, and the oblique abutment block 2213 and the clamping block 2212 are in a clamping state under the squeezing action; when the push rod 41 moves from the second station to the first station, the extension rod 411 on the push rod 41 separates from the oblique abutment block 2213, and the two movable supports 221 are in an open state under the elastic force of the first elastic member 2211.

[0035] The present invention realizes the function of controlling the opening and closing of the clamping assembly 22 through the movable support 221, the first elastic member 2211, the clamping block 2212, the oblique abutment block 2213 and the push rod 41, and utilizes the squeezing and separation of the extension rod 411 and the oblique abutment block 2213 to achieve the effect of automatically controlling the opening and closing of the clamping block 2212 in the process of driving the slide 21 to move back and forth. In the process of pushing the slide 21 to reciprocate on the base 1 by the reciprocating propulsion assembly 23, when the slide 21 moves from the first station to the second station, the reciprocating propulsion assembly 23 drives the push rod 41, and the extension rod 411 on the push rod 41 squeezes the oblique abutment block 2213, and the two extension rods 411 on both sides squeeze the oblique abutment blocks 2213 on the two movable supports 221 at the same time, driving the two clamping blocks 2212 to approach each other, and the clamping blocks 2212 clamp the flexible cable 31, and then the extension rod 411 on the push rod 41 pushes the movable support 221 to move, and then the slide 21 is driven by the movable support 221 to push the flexible cable 31 and the dredging head 32 deep into the pipeline to dredge and clean the pipeline. During the pushing process, the extension rod 411 and the oblique abutment block 2213 are always abutted. When the slide 21 moves from the second station to the first station, the push rod 41 drives the extension rod 411 to move in the opposite direction. The push rod 41 separates from the oblique abutment block 2213 during the movement and no longer presses the oblique abutment block 2213, and the clamping assembly releases the flexible cable 31. Then the extension rod 411 on the push rod 41 pushes the movable support 221, thereby controlling the slide 21 to reset, and repeating the above actions to complete the intermittent advancement of the dredging head 32.

[0036] Reference Figure 2-Figure 4 : Each movable support 221 is provided with two connecting seats 2214, and the extension rod 411 is located between the two connecting seats 2214; two mounting frames 211 are provided on the slide 21, and each mounting frame 211 is provided with two limiting components 42 for limiting the movement of the connecting seats 2214, and the two limiting components 42 on the mounting frame 211 are respectively located at the first station and the second station.

[0037] The present invention realizes the function of limiting the movement of the movable support 221 during the separation or abutment between the extension rod 411 and the oblique abutment block 2213 through the mounting frame 211, the connecting seat 2214 and the limiting assembly 42, thereby preventing the extension rod 411 from pushing the movable support 221 to move when squeezing the oblique abutment block 2213.

[0038] When the slide 21 is in the first station, the limit assembly 42 located in the first station limits the movement of the connecting seat 2214 close to the second station, thereby limiting the movable support 221 from moving toward the second station. At this time, the slide 21 is in the first station, that is, the slide 21 is located at the end of the base 1 and cannot continue to move in the direction away from the second station. At this time, the operator drives the push rod 41 to move toward the second station through the reciprocating propulsion assembly 23, and the push rod 41 drives the extension rod 411 to move. After the extension rod 411 contacts the oblique abutment block 2213, it squeezes the oblique abutment block 2213, and then the elastic force of the first elastic member 2211 is overcome by the squeezing force to push the movable support 221 to move. When the two extension rods 411 squeeze the two oblique abutment blocks 2213 at the same time, the first elastic member 2211 contracts, and the two clamping blocks 2212 approach each other to clamp the flexible cable 31. When the extension rod 411 on the push rod 41 contacts the connecting seat 2214 near the second workstation, the operator releases the movement restriction of the connecting seat 2214 by the limit assembly 42, and the extension rod 411 pushes the connecting seat 2214 to move, and the connecting seat 2214 drives the movable support 221 and the slide 21 to move, thereby pushing the flexible cable 31 and the dredging head 32 forward.

[0039] When the slide 21 moves to the second station, the limit assembly 42 located at the second station limits the movement of the connecting seat 2214 near the first station. At this time, the reciprocating propulsion assembly 23 drives the push rod 41 to move toward the first station, and the push rod 41 drives the extension rod 411 to move. The extension rod 411 separates from the oblique abutment block 2213 during the movement, and the two movable supports 221 separate under the elastic force of the first elastic member 2211 until the extension rod 411 abuts against the clamping block 2212. When the extension rod 411 contacts the connecting seat 2214 near the first station, it pushes the connecting seat 2214, and then drives the movable support 221 and the slide 21 to move toward the first station through the connecting seat 2214.

[0040] When the two movable supports 221 are separated by the elastic force of the first elastic member 2211, the two clamping blocks 2212 are respectively abutted against the two extension rods 411 through the elastic force of the first elastic member 2211, and the flexible cable 31 is located between the two clamping blocks 2212, thereby preventing the slide 21 from contacting and rubbing with the flexible cable 31 during the resetting process.

[0041] Reference Figure 4 and Figure 5 : A fourth elastic member 2215 is provided on the oblique abutment block 2213, and the oblique abutment block 2213 is slidably matched with the clamping block 2212, and two ends of the fourth elastic member 2215 are respectively connected to the oblique abutment block 2213 and the clamping block 2212.

[0042] The present invention realizes the elastic buffering function between the clamping block 2212 and the oblique abutting block 2213 through the fourth elastic member 2215. When the oblique abutting block 2213 is squeezed by the extension rod 411, the fourth elastic member 2215 contracts under the squeezing action, and the oblique abutting block 2213 pushes the clamping block 2212 and the movable support 221 through the elastic force provided by the fourth elastic member 2215, and the flexible cable 31 is clamped by the mutual approach of the two clamping blocks 2212. Through the deformation ability of the fourth elastic member 2215, the clamping block 2212 can stably clamp the flexible cables 31 of different diameters.

[0043] Reference Figure 4 and Figure 7 : The limiting component 42 includes a block 421 and a second elastic member 422; a mounting groove for accommodating the block 421 is opened on the mounting frame 211, and the block 421 is telescopically arranged in the mounting groove; the two ends of the second elastic member 422 are respectively connected to the block 421 and the groove wall of the mounting groove; a control component 43 for controlling the contraction of the block 421 is provided on the connecting seat 2214, and when the block 421 is in an extended state and the block 421 abuts against the connecting seat 2214, the movement of the connecting seat 2214 is limited.

[0044] The present invention realizes the function of limiting the movement of the connecting seat 2214 through the block 421, the second elastic member 422 and the control assembly 43. When the slide 21 is in the first station, the block 421 is in an extended state, and the block 421 abuts against the connecting seat 2214 near the second station, limiting the movement of the connecting seat 2214 toward the second station. When the extension rod 411 moves toward the second station under the push of the reciprocating propulsion assembly 23, the extension rod 411 squeezes the oblique abutment block 2213, thereby pushing the two movable supports 221 closer to each other, and the movable support 221 drives the clamping block 2212 to move, and the flexible cable 31 is clamped by the two clamping blocks 2212. When the extension rod 411 abuts against the connecting seat 2214, the control assembly 43 controls the block 421 to shrink, the second elastic member 422 shrinks under the squeezing action, the block 421 separates from the connecting seat 2214, and then releases the movement restriction of the limiting assembly 42 on the connecting seat 2214.

[0045] Reference Figure 5-Figure 7: The control component 43 includes a guide rod 431 and a first push block 432; the guide rod 431 is slidably installed on the connecting seat 2214, and the first push block 432 is arranged at the end of the guide rod 431 away from the extension rod 411; the block 421 is provided with a first inclined surface 4211 and a second inclined surface 4212; in the working state, when the connecting seat 2214 moves from the first inclined surface 4211 to the second inclined surface 4212 of the block 421, the connecting seat 2214 squeezes the first inclined surface 4211 of the block 421, and the block 421 contracts under the action of the squeezing force; when the first push block 432 moves from the second inclined surface 4212 to the first inclined surface 4211, the first push block 432 squeezes the second inclined surface 4212, and the block 421 contracts under the action of the squeezing force.

[0046] The present invention realizes the function of controlling the contraction of the card block 421 through the guide rod 431 and the first push block 432. When the slide 21 is in the first station and the push rod 41 pushes the movable support 221 toward the second station, the first push block 432 on the connecting seat 2214 near the second station is controlled to squeeze the second inclined surface 4212 of the card block 421, driving the card block 421 to contract, and releasing the movement restriction of the connecting seat 2214 by the limit assembly 42. When the slide 21 moves from the first station to the second station, when the connecting seat 2214 of the movable support 221 close to the second station contacts the block 421 located at the second station, the connecting seat 2214 squeezes the first inclined surface 4211 of the block 421, thereby driving the block 421 to shrink until the movable support 221 passes through the block 421. After losing the squeezing effect, the block 421 extends out under the elastic force of the second elastic member 422. At this time, the block 421 abuts against the connecting seat 2214 on the movable support 221 close to the first station, thereby limiting the movement of the connecting seat 2214.

[0047] Reference Figure 5-Figure 7 : A second push block 433 is provided at one end of the guide rod 431 close to the extension rod 411; a third elastic member 434 is provided on the second push block 433, and both ends of the third elastic member 434 are respectively connected to the second push block 433 and the connecting seat 2214.

[0048] The present invention realizes the function of pushing the guide rod 431 and the first push block 432 to move through the movement of the extension rod 411 through the second push block 433 and the third elastic member 434. When the slide 21 is in the first station and the push rod 41 pushes the movable support 221 in the direction close to the second station, the extension rod 411 on the push rod 41 pushes the second push block 433, and the third elastic member 434 contracts under the action of the thrust, and the second push block 433 drives the first push block 432 to move through the guide rod 431, and the first push block 432 squeezes the second inclined surface 4212 of the card block 421, driving the card block 421 to contract, and releasing the movement restriction of the limit assembly 42 on the connecting seat 2214. The movement of the extension rod 411 automatically drives the guide rod 431 and the first push block 432 on the connecting seats 2214 on both sides to move.
