Description

Technical Field

[0001] This application relates to the field of pipeline cleaning equipment technology, specifically an auxiliary device for cleaning silt and sand from pipelines using the bottom-dragging method. Background Technology

[0002] Currently, the cleaning of silt in pipelines is mostly done using the bottom-dragging method. This involves inserting a high-pressure nozzle into the pipeline to spray high-pressure water to impact the silt, while simultaneously moving the water pipe connected to the high-pressure nozzle manually or mechanically, thus cleaning the silt along the entire length of the pipeline.

[0003] Chinese utility model patent CN222990888U discloses a trenchless pipeline sludge removal device. It utilizes an electric reel, rotating nozzles, a oscillating water pipe, and a cutting ring to efficiently remove stubborn sludge from pipes of different sizes. However, because it directly uses the electric reel to wind up and down the water pipe, the pipe is only subject to the winding force of the reel during this process. Due to the flexible nature of the water pipe, it is prone to irregular displacement and stacking as the reel rotates without directional constraints, easily leading to entanglement and bending. This results in a sharp reduction in the water flow cross-sectional area, causing water pressure loss, reducing the impact force of the high-pressure nozzle, and affecting the sludge removal effect. Furthermore, the turbulent water flow at the bends can also cause nozzle blockage.

[0004] Therefore, this application provides an auxiliary device for cleaning silt from pipelines using the bottom-dragging method to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an auxiliary device for bottom-dragging pipeline mud and sand cleaning, which aims to solve the problems mentioned in the background art, such as the existing water spray pipe being wound and unwound by an electric reel, where the water spray pipe is only subject to winding traction force and is not directionally constrained due to its own flexibility, which makes it prone to irregular deviation, stacking, tangling and bending during winding and unwound, resulting in water pressure loss, reduced cleaning effect and nozzle blockage.

[0006] To achieve the above objectives, this application provides the following technical solution: a bottom-dragging method pipe silt cleaning auxiliary device, including a base, a water pipe for connecting to a water source, a high-pressure nozzle fixedly connected to the end of the water pipe away from the water source, and a winding structure set on the base for winding and unwinding the water pipe. The pipe silt cleaning auxiliary device also includes a guide traction structure set on the base and connected to the winding structure for traction and guidance during the winding and unwinding of the water pipe.

[0007] The guiding and traction structure includes a lead screw rotatably connected to the base and located on one side of the winding structure, a slider screwed onto the lead screw, a movable seat slidably connected to the top of the base and located above the slider, a guide roller rotatably connected between the slider and the movable seat and located at the corners of both for limiting and guiding both sides of the water pipe, and a transmission component disposed on one side of the base and connected to the lead screw and the winding structure for transmitting power from the winding structure to the lead screw, causing the slider to drive the movable seat and the guide roller to move reciprocally horizontally. The transmission component transmits power from the winding structure to the lead screw, causing the lead screw to rotate synchronously, so that the slider screwed onto the lead screw drives the movable seat and the guide roller. The guide roller forms a limiting constraint and guidance for the water pipe, which can realize the traction and guidance during the winding and unwinding of the water pipe, prevent the water pipe from tangling or bending during the winding and unwinding process, ensure a constant cross-sectional area of ​​water flow in the water pipe to avoid water pressure loss, thereby improving the mud and sand cleaning effect and efficiency of the high-pressure nozzle and reducing the probability of nozzle clogging.

[0008] Preferably, to achieve the winding and unwinding of the water pipe, the winding structure includes a winding roller rotatably connected to the base and located on one side of the lead screw, a fixed frame fixedly installed on one side of the base, and a motor fixedly installed on the fixed frame. The output shaft of the motor is fixedly connected to one end of the winding roller, and the water pipe is wound around the winding roller. By driving the winding roller to rotate through the motor, the water pipe wound on the winding roller completes the winding and unwinding action with the forward and reverse rotation of the winding roller, thereby replacing manual winding and unwinding of the water pipe and improving winding and unwinding efficiency. The fixed frame provides stable support for the motor and the winding roller.

[0009] Preferably, to ensure the stability of winding and unwinding, a pressure roller is rotatably connected to the base for abutting against the surface of the water pipe. The pressure roller is located on the side of the take-up roller closer to the lead screw. The pressure roller abuts against the surface of the water pipe and uses its own pressure to form a pressure constraint on the water pipe, so that the water pipe is tightly wrapped against the surface of the take-up roller, thereby preventing the water pipe from loosening or shifting during the winding process and improving the winding quality.

[0010] Preferably, in order to achieve power linkage between the winding structure and the guiding traction structure, the transmission assembly includes two sprockets rotatably connected to the fixed frame and respectively fixedly sleeved on one end of the winding roller and one end of the lead screw, and a chain wound around the two sprockets. The two sprockets are connected and transmit power through the chain. When the winding roller rotates, it drives the sprocket fixedly sleeved with it to rotate synchronously. Through the transmission action of the chain, the power can be transmitted to the sprocket fixedly sleeved with the lead screw, thereby driving the lead screw to rotate, thus ensuring that the winding and guiding actions are synchronized and coordinated.

[0011] Preferably, to protect the lead screw, telescopic bellows are provided on both sides of the lead screw corresponding to the slider. The two ends of the telescopic bellows are fixedly connected to the side of the slider and the side wall of the base, respectively. The design of the telescopic bellows allows it to expand and contract synchronously with the reciprocating movement of the slider, always covering the area on both sides of the lead screw corresponding to the slider, thereby isolating impurities such as mud and dust, preventing impurities from adhering to the surface of the lead screw or entering the screw gap between the lead screw and the slider, avoiding corrosion or jamming of the lead screw, and ensuring smooth movement of the slider.

[0012] Preferably, in order to clean the mud and sand impurities attached to the surface of the water pipe simultaneously during the water pipe winding and unwinding process, a cleaning component for cleaning the surface of the water pipe is provided on the side of the slider away from the guide roller; the design of the cleaning component can remove mud and sand impurities from the surface of the water pipe in a timely manner, reducing the amount of impurities that enter the winding roller with the water pipe winding, affecting the winding of the water pipe or affecting the rotation of the winding roller.

[0013] Preferably, to achieve water pipe cleaning, the cleaning assembly includes a mounting bracket fixedly installed on the side of the slider away from the guide roller for the water pipe to pass through; a sleeve sleeved on the outside of the water pipe and fixedly connected to the mounting bracket on the side away from the guide roller; high-pressure nozzles fixedly connected to the sleeve and arranged in a ring; a pump body fixedly installed on one side of the base for connection to a water source; and a hose fixedly connected to the pump body at the end away from the water source. The end of the hose away from the pump body is fixedly connected to the sleeve. The high-pressure nozzles are inclined towards the surface of the water pipe. After the pump body draws water and pressurizes it, it is transported to the sleeve through the hose. Then, high-pressure water is sprayed through the ring-arranged high-pressure nozzles inclined towards the surface of the water pipe, which can wash away impurities on the surface of the water pipe, thereby removing mud and sand impurities from the surface of the water pipe, preventing impurities from entering the take-up roller with the water pipe, and reducing the wear of impurities on the outer wall of the water pipe or affecting the rotation of the take-up roller.

[0014] This bottom-dragging pipeline sludge cleaning auxiliary device transmits power from the winding structure to the lead screw through a transmission component, causing the lead screw to rotate synchronously. This causes the slider screwed to the lead screw to drive the moving seat and guide roller. The guide roller forms a limiting constraint and guide for the water pipe, which can realize the traction and guidance of the water pipe during winding and unwinding. This prevents the water pipe from getting tangled or bent during the winding and unwinding process, ensures that the cross-sectional area of ​​the water flow inside the water pipe is constant to avoid water pressure loss, and thus improves the sludge cleaning effect and efficiency of the high-pressure nozzle, and reduces the probability of nozzle clogging.

[0015] This bottom-drag method pipeline mud and sand cleaning auxiliary device can remove mud and sand impurities from the surface of water pipes in a timely manner by setting up cleaning components, reducing the amount of impurities that enter the winding roller with the water pipe and affect the winding of the water pipe or the rotation of the winding roller.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Example 1

[0029] This embodiment provides an auxiliary device for bottom-drag pipe sludge cleaning, such as... Figures 1-3As shown, the pipeline silt cleaning auxiliary device includes a base 1, a water pipe 2 for connecting to a water source, a high-pressure nozzle 3 fixedly connected to the end of the water pipe 2 away from the water source, and a winding structure 4 set on the base 1 for winding and unwinding the water pipe 2. The pipeline silt cleaning auxiliary device also includes a guide traction structure 5 set on the base 1 and connected to the winding structure 4 for traction and guidance during the winding and unwinding of the water pipe 2. The guide traction structure 5 includes a lead screw 51 rotatably connected to the base 1 and located on one side of the winding structure 4, a slider 52 screwed to the lead screw 51, a movable seat 53 slidably connected to the top of the base 1 and located above the slider 52, a guide roller 54 rotatably connected between the slider 52 and the movable seat 53 and located at the corners of both for limiting and guiding both sides of the water pipe 2, and a transmission component 55 set on one side of the base 1 and connected to the lead screw 51 and the winding structure 4 for transmitting power from the winding structure 4 to the lead screw 51, so that the slider 52 drives the movable seat 53 and the guide roller 54 to move horizontally back and forth.

[0030] It should be noted that the high-pressure nozzle 3 is a self-propelled nozzle. Its working principle is that when the high-pressure water flow is sprayed out of the nozzle, it will generate a reverse thrust, which drives the high-pressure nozzle 3 to move forward autonomously in the pipeline. With the help of the water pipe 2 winding structure 4 and the limiting guidance of the guiding traction structure 5, the pipeline mud and sand can be efficiently cleaned.

[0031] In order to protect the lead screw 51, telescopic bellows 511 are provided on both sides of the lead screw 51 corresponding to the slider 52. The two ends of the telescopic bellows 511 are fixedly connected to the side of the slider 52 and the side wall of the base 1, respectively. The design of the telescopic bellows 511 can extend and retract synchronously with the reciprocating movement of the slider 52, always covering the area on both sides of the lead screw 51 corresponding to the slider 52, thereby isolating impurities such as mud and dust, preventing impurities from adhering to the surface of the lead screw 51 or entering the screw gap between the lead screw 51 and the slider 52, avoiding corrosion or jamming of the lead screw 51, and ensuring smooth movement of the slider 52.

[0032] When using the bottom-dragging method for cleaning silt from pipes, first connect water pipe 2 to a water source, which can be stored water in a bucket or other regularly supplied water from other pipes. Then, use a booster pump or high-pressure pump to deliver the water to water pipe 2 and pressurize it. The high-pressure water flows through water pipe 2 to a high-pressure nozzle 3 fixedly connected to the end of water pipe 2 away from the water source. Under the impact of the high-pressure water, the high-pressure nozzle 3 moves back and forth in the pipe to flush away the silt. During this process, the winding structure 4 set on the base 1 starts synchronously, and the water pipe 2 is wound up and down according to the moving direction of the high-pressure nozzle 3. When the winding structure 4 is running, the power is transmitted to the lead screw 51 rotatably connected to the base 1 through the transmission component 55 connected to it. The screw 51 is driven to rotate synchronously. At this time, the slider 52 screwed on the screw 51 moves horizontally back and forth along the axis of the screw 51. The slider 52 drives the movable seat 53 slidably connected to the top of the base 1 to move synchronously, which in turn drives the guide rollers 54 rotatably connected to the corners of the slider 52 and the movable seat 53 to move synchronously. During this process, the water pipe 2 passing between the four guide rollers 54 is pulled to move horizontally back and forth, which can realize the limiting guidance of the water pipe 2 during the opening and closing process, prevent the water pipe 2 from bending, and thus ensure that the cross-sectional area of ​​the water flow in the water pipe 2 is constant to avoid affecting the water output efficiency, thereby stabilizing the water pressure of the high-pressure nozzle 3 and preventing the high-pressure nozzle 3 from being blocked due to the water flow being obstructed by the bending of the water pipe 2.

[0033] Specifically, the winding structure 4 includes a winding roller 41 rotatably connected to the base 1 and located on one side of the lead screw 51, a fixed frame 42 fixedly installed on one side of the base 1, and a motor 43 fixedly installed on the fixed frame 42. The output shaft of the motor 43 is fixedly connected to one end of the winding roller 41, and the water pipe 2 is wound around the winding roller 41.

[0034] In addition, to ensure the stability of winding and unwinding, a pressure roller 11 is rotatably connected to the base 1 for abutting against the surface of the water pipe 2. The pressure roller 11 is located on the side of the take-up roller 41 near the lead screw 51. The pressure roller 11 abuts against the surface of the water pipe 2 and uses its own pressure to form a pressure constraint on the water pipe 2, so that the water pipe 2 is tightly wrapped against the surface of the take-up roller 41, thereby preventing the water pipe 2 from loosening or shifting during the winding process and improving the winding quality.

[0035] When the water pipe 2 needs to be wound up or unwound, the motor 43, which is fixedly mounted on the fixed frame 42, starts. The output shaft of the motor 43 drives the winding roller 41, which is fixedly connected to it, to rotate. When the winding roller 41 rotates, it will wind up or unwind the water pipe 2 wrapped around its surface. The fixed frame 42 provides stable support for the motor 43 and the winding roller 41, which is rotatably connected to the base 1. During the winding up or unwinding of the water pipe 2, the pressure roller 11 abuts against the surface of the water pipe 2, which allows the water pipe 2 to fit tightly against the surface of the winding roller 41 and complete the winding up or unwinding action as the winding roller 41 rotates, thus preventing the water pipe 2 from loosening or shifting when winding up.

[0036] Furthermore, the transmission assembly 55 includes two sprockets 551 rotatably connected to the fixed frame 42 and respectively fixedly sleeved on one end of the take-up roller 41 and one end of the lead screw 51, and a chain 552 wound around the two sprockets 551. The two sprockets 551 are connected and transmit power through the chain 552.

[0037] When the water pipe 2 is wound up and down through the winding structure 4, the motor 43 drives the winding roller 41 to rotate. The sprocket 551, which is fixedly sleeved at one end of the winding roller 41 and rotatably connected to the fixed frame 42, will also rotate synchronously with the winding roller 41. Since the two sprockets 551 are connected and transmit power through the chain 552, when the sprocket 551 on the winding roller 41 rotates, the power will be transmitted through the chain 552 to the sprocket 551, which is fixedly sleeved at one end of the lead screw 51 and rotatably connected to the fixed frame 42, thereby driving the lead screw 51 to rotate synchronously. This realizes the transmission of the rotational power of the winding roller 41 to the lead screw 51, ensuring that the winding up and down and traction guidance of the water pipe 2 are synchronized.

[0038] Example 2

[0039] Unlike Example 1, as Figure 1 and Figure 4 As shown, a cleaning component 6 for cleaning the surface of the water pipe 2 is provided on the side of the slider 52 away from the guide roller 54. The cleaning component 6 includes a mounting bracket 61 fixedly installed on the side of the slider 52 away from the guide roller 54 for the water pipe 2 to pass through, a sleeve 62 sleeved on the outside of the water pipe 2 and fixedly connected to the side of the mounting bracket 61 away from the guide roller 54, high-pressure nozzles 63 fixedly connected to the sleeve 62 and arranged in a ring, a pump body 64 fixedly installed on one side of the base 1 for connecting to the water source, and a hose 65 fixedly connected to the end of the pump body 64 away from the water source. The end of the hose 65 away from the pump body 64 is fixedly connected to the sleeve 62. The high-pressure nozzles 63 are inclined towards the side closer to the surface of the water pipe 2.

[0040] During the retraction and extension of the water pipe 2, the pump body 64 of the cleaning component 6, which is fixedly installed on the side of the slider 52 away from the guide roller 54, starts synchronously. After the pump body 64 starts, it draws water from the connected water source. Then, the water pump body 64 pressurizes the water and delivers it to the sleeve 62 through the fixedly connected hose 65. The high-pressure water delivered to the sleeve 62 is sprayed through the high-pressure nozzles 63 distributed in a ring on it. Since the high-pressure nozzles 63 are inclined towards the surface of the water pipe 2, a high-pressure water flow towards the surface of the water pipe 2 can be formed. Thus, as the water pipe 2 moves and the slider 52 moves back and forth, the water flow sprayed by the high-pressure nozzles 63 can wash away the mud and sand impurities attached to the surface of the water pipe 2 in time, reducing the impurities from being wound onto the winding roller 41 with the water pipe 2 and affecting the winding of the water pipe 2. At the same time, due to the flexible nature of the hose 65, it can deform synchronously with the retraction and extension of the water pipe 2 and the movement of the slider 52, without interfering with the retraction and extension of the water pipe 2, ensuring that the cleaning and retraction operations are carried out in a coordinated manner.

[0041] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
