Description

Technical Field

[0001] This utility model relates to the field of underground pipeline dredging technology, and more specifically, to a device for dredging underground pipelines. Background Technology

[0002] In the production system of large chemical enterprises, underground pipelines play a crucial role in transporting liquids. However, due to the complex production environment, various debris, waste residues and sediments can easily accumulate inside the pipelines, leading to problems with poor water flow. Once a blockage occurs, it will not only reduce production efficiency, but may also cause corrosion to the pipeline due to liquid stagnation, shorten the pipeline's service life, and increase maintenance costs.

[0003] Traditional pipe dredging methods, such as high-pressure cleaning equipment and manual dredging, have significant drawbacks. High-pressure cleaning requires shutting off the water supply beforehand, otherwise the high-pressure water flow cannot effectively target the blockage. Moreover, the cleaning process is time-consuming, and the wastewater needs to be specially treated afterward. Manual dredging is not only inefficient but also poses safety risks. It also requires operation under water outage conditions. However, in actual production, chemical companies have extremely high requirements for the continuity of water supply. Once the water supply is cut off, a series of production processes will be forced to stop, resulting in serious economic losses.

[0004] In view of this, the present invention proposes a device for unblocking underground pipes. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for dredging underground pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for dredging underground pipelines, comprising a steel pipe, both ends of which are connected to steel wire ropes, and a buckle structure is provided at the connection point between one end of each steel wire rope and the steel pipe, and the other end of one of the steel wire ropes is connected to a driving structure.

[0007] To improve the unblocking range and effectiveness, preferably, the steel pipe has multiple sets of sleeves fixedly distributed in a ring on its surface. A sleeve rod is slidably mounted inside each sleeve. A limit block is located at one end of the sleeve rod inside the sleeve. A compression spring is located at one end of the limit block, and a mounting block is located at the other end of the sleeve rod. A sliding ball is rolled on the mounting block. The outer wall of the limit block is slidably connected to the inner wall of the sleeve, and the outer diameter of the limit block is larger than the opening of the sleeve. The limit block is used to prevent the sleeve rod from detaching from the inside of the sleeve. The two ends of the compression spring are connected to the limit block and the inner wall of the sleeve, respectively.

[0008] In order to connect the wire rope to the steel pipe, preferably, the buckle structure includes a connecting rod, which is fixed to one end of the steel pipe and has a ring fixedly provided at one end of the connecting rod. A pressure plate is fixedly provided at one end of the wire rope. A U-shaped clamp is provided inside the ring, and two locking nuts are installed on the U-shaped clamp. The pressure plate is installed on the U-shaped clamp and slides with the U-shaped clamp. Both locking nuts are threadedly connected to the U-shaped clamp.

[0009] In order to provide power for dragging the steel pipe, the drive structure is preferably a winch, which consists of a support, a take-up roller and a motor. The take-up roller is rotatably connected inside the support, and the motor is fixedly installed on the outer wall of the support, with the output end of the motor fixedly connected to the take-up roller.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This application utilizes a winch as a driving structure to provide a stable and large drag force, which can effectively drive the steel pipe to move in the underground pipeline, so that the sleeve and sleeve rod can fully contact the blockage and generate friction, thereby clearing the blockage and ensuring the smooth flow of the pipeline.

[0012] The sleeve rod can slide inside the sleeve and compress the spring, so that the mounting block fits tightly against the inner wall of the pipe, expanding the unblocking range and improving the unblocking efficiency. It can better deal with blockages in different locations of the pipe. The sliding ball on the mounting block rolls during the dragging process to avoid jamming, ensuring smooth movement of the steel pipe and further improving the unblocking effect.

[0013] 2. By setting up a buckle structure, using U-shaped clamps, pressure plates and locking nuts, a stable connection between the wire rope and the steel pipe can be achieved. The operation is relatively simple during installation. Just pass the U-shaped clamp through the ring, slide the pressure plate and tighten the locking nut to complete the connection. It is convenient and quick, and can ensure the reliability of the connection during dragging. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1-5 The device shown is for unblocking underground pipes, including a steel pipe 1, with steel wire ropes 2 connected to both ends of the steel pipe 1. Each end of the two steel wire ropes 2 is connected to the steel pipe 1 with a buckle structure, and the other end of one of the steel wire ropes 2 is connected to a drive structure.

[0022] The surface of the steel pipe 1 has multiple sets of sleeves 3 fixedly distributed in a ring. A sleeve rod 4 is slidably arranged inside the sleeve 3. A limit block 5 is set at one end of the sleeve rod 4 inside the sleeve 3. A compression spring 6 is set at one end of the limit block 5. An installation block 7 is set at the other end of the sleeve rod 4. A sliding ball 8 is rolled on the installation block 7. The outer wall of the limit block 5 is slidably connected to the inner wall of the sleeve 3, and the outer diameter of the limit block 5 is larger than the opening of the sleeve 3. The limit block 5 is used to prevent the sleeve rod 4 from detaching from the inside of the sleeve 3. The two ends of the compression spring 6 are connected to the limit block 5 and the inner wall of the sleeve 3, respectively.

[0023] Specifically, in this structure, one end of each of the two steel wire ropes 2 is connected to both ends of the steel pipe 1 via a snap-fit ​​structure, and the other end of one of the steel wire ropes 2 is connected to the drive structure. This structure is pre-installed inside the underground pipeline when it is unobstructed. Underground wells are installed at intervals along the underground pipeline; in this application, these are designated as well 1 and well 2, respectively, as shown in the attached diagram. Figure 5 As shown, place the steel pipe 1 and the steel wire rope 2 at one end in the well 1 and fix them in place. The steel wire rope 2 at the other end of the steel pipe 1 is passed through the underground pipe and placed in the well 2.

[0024] When the underground pipeline is blocked, steel pipe 1 is inserted into the underground pipeline, and the steel wire rope 2 reserved at the other end of the wellhead is fixed to the drive structure. By starting the drive structure, steel pipe 1 is dragged, so that the sleeve 3 and sleeve rod 4 on the surface of steel pipe 1 come into contact with the blockage and generate friction, thereby breaking and removing the blockage.

[0025] The sleeve rod 4 can slide inside the sleeve 3 and squeeze the compression spring 6 through the limiting block 5, which can adjust the length between the sleeve 3 and the sleeve rod 4, and make the mounting block 7 at one end of the sleeve rod 4 fit against the inner wall of the underground pipe, which can greatly improve the unblocking range of the blockage. In addition, during the process of dragging the steel pipe 1, the sliding ball 8 rolls on the surface of the mounting block 7 to avoid jamming.

[0026] In this embodiment, as shown in the appendix Figure 1 , 4 As shown, the buckle structure includes a connecting rod 9, which is fixed to one end of the steel pipe 1. A ring 10 is fixedly installed at one end of the connecting rod 9, and a pressure plate 11 is fixedly installed at one end of the wire rope 2. A U-shaped clamp 12 is installed inside the ring 10. Two locking nuts 13 are installed on the U-shaped clamp 12. The pressure plate 11 is installed on the U-shaped clamp 12 and slides with the U-shaped clamp 12. Both locking nuts 13 are threadedly connected to the U-shaped clamp 12.

[0027] Specifically, in this structure, when the wire rope 2 is connected to the steel pipe 1 through the buckle structure, the U-shaped clamp 12 is first passed through the ring 10, and the pressure plate 11 at one end of the wire rope 2 is slid on the U-shaped clamp 12, so that the pressure plate 11 squeezes the U-shaped clamp 12. Finally, the pressure plate 11 and the U-shaped clamp 12 are locked and fixed by two locking nuts 13, thereby completing the connection between the wire rope 2 and the steel pipe 1.

[0028] In this embodiment, as shown in the appendix Figure 1 As shown, the drive structure is specifically a winch, which consists of a support 14, a take-up roller 15 and a motor 16. The take-up roller 15 is rotatably connected inside the support 14, and the motor 16 is fixedly installed on the outer wall of the support 14, with the output end of the motor 16 fixedly connected to the take-up roller 15.

[0029] Specifically, in this structure, when the steel pipe 1 is dragged using the drive structure, one end of the wire rope 2 is first connected to the winding roller 15. At this time, the motor 16 drives the winding roller 15 to rotate inside the bracket 14. The rotation of the winding roller 15 can wind up the wire rope 2, thereby providing power for dragging the steel pipe 1 inside the underground pipeline.

[0030] Working principle of this utility model:

[0031] This application provides a device for unblocking underground pipelines, mainly used to unblock debris, waste residue and sediment in underground pipelines during the production of large chemical enterprises. In specific use;

[0032] First, when the underground pipeline is unobstructed, connect the two wire ropes 2 to both ends of the steel pipe 1 through the buckle structure. Specifically, pass the U-shaped clamp 12 through the ring 10 on the connecting rod 9 at one end of the steel pipe 1, slide the pressure plate 11 at one end of the wire rope 2 onto the U-shaped clamp 12, and then use two locking nuts 13 to lock and fix the pressure plate 11 and the U-shaped clamp 12. After that, connect the other end of one of the wire ropes 2 to the winding roller 15 of the winch. Then, place the steel pipe 1 and the wire rope 2 at one end in the well 1 and fix them. Let the wire rope 2 at the other end of the steel pipe 1 pass through the underground pipeline, leaving the rope end in the well 2, so that the device is in standby mode inside the underground pipeline.

[0033] When the underground pipeline is blocked, insert the steel pipe 1 at well 1 into the underground pipeline, then fix the steel wire rope 2 reserved at well 2 to the winding roller 15 of the winch, start the winch, the motor 16 drives the winding roller 15 to rotate, the winding roller 15 begins to wind up the steel wire rope 2, thereby generating a pulling force to drag the steel pipe 1 to move inside the underground pipeline.

[0034] During the movement of the steel pipe 1, the sleeve 3 and the sleeve rod 4 on its surface will come into contact with the blockage. Since the sleeve rod 4 can slide inside the sleeve 3, when it encounters the blockage, the sleeve rod 4 will slide into the sleeve 3 and squeeze the limiting block 5. The limiting block 5 compresses the spring 6. This elastic structure allows the mounting block 7 at one end of the sleeve rod 4 to fit tightly against the inner wall of the underground pipe, increasing the contact area and friction with the blockage, thereby breaking and clearing the blockage. At the same time, the sliding ball bearing 8 on the mounting block 7 rolls during the dragging process, reducing the friction between the mounting block 7 and the inner wall of the pipe, avoiding jamming, ensuring that the steel pipe 1 can move smoothly, and improving the unblocking effect.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
