Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning devices, and in particular to a gas-water pulse pipeline cleaning device. Background Technology

[0002] With the widespread adoption of urban infrastructure and industrial pipeline systems, the accumulation of dirt, rust, and deposits on the inner walls of pipes over long-term use can easily lead to reduced flow efficiency, water pollution, and even pipe blockage. Air-water pulse cleaning technology, due to its high efficiency in cleaning the inner walls of pipes through the mixing of high-speed pulsed airflow and water flow, is widely used in various pipeline maintenance scenarios. Developing a cleaning device with a flexible connection structure and stable fixing performance to meet the cleaning needs of pipes of different diameters and lengths has become a key direction for improving the efficiency and applicability of cleaning operations.

[0003] In existing technologies, pipeline cleaning devices mostly use traditional flange connections or threaded connections, achieving the connection between the pipeline and the cleaning equipment through the mechanical engagement of rigid components. This type of connection relies on manual precision alignment of bolt holes or thread tightening, making the installation process cumbersome and time-consuming, especially in scenarios requiring frequent replacement or extension of the delivery pipe, resulting in low operational efficiency. Regarding fixing devices, some equipment uses hydraulic clamping or snap-fit ​​structures, achieving positioning by mechanically squeezing the outer wall of the pipeline. The fixing force is difficult to control precisely, and its adaptability to pipelines of different materials (such as plastic and metal) or different outer diameters is poor.

[0004] Traditional pulse pipeline cleaning devices typically use rigid connections for the delivery pipes, which are difficult to adapt to pipes of various diameters and require multiple sets of accessories of different specifications, increasing equipment costs and operational complexity. This invention, however, effectively solves these technical problems through the design of an elastic sealing structure and adjustable connection components. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas-water pulse pipeline cleaning device, which aims to improve the problem that the delivery pipe of the traditional pulse pipeline cleaning device usually adopts a rigid connection method, which is difficult to flexibly adapt to pipelines of various diameters and requires multiple sets of accessories of different specifications, increasing the equipment cost and operational complexity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas-water pulse pipeline cleaning device, including a connecting seat, a fixing ring fixedly connected to the bottom of the connecting seat, a conveying pipe provided on the inner wall of the fixing ring, a rotating shaft fixedly connected to one end of the fixing ring, a movable ring fixedly connected to the outer wall of the rotating shaft, a screw rotatably connected to the other end of the fixing ring, a nut fixedly connected to the outer wall of the screw, a washer threadedly connected to the outer wall of the nut, a gas-water pulse flushing device body fixedly connected to the top of the connecting seat, and a sealing component provided on one side of the outer wall of the fixing ring;

[0007] The sealing assembly includes a fixing ring and a sealing ring. The outer wall of the fixing ring is fixedly connected to one side of the outer wall of the fixing ring. The sealing ring is slidably connected inside the fixing ring. A telescopic rod is provided inside the sealing ring, and a spring is sleeved on the outer wall of the telescopic rod.

[0008] Furthermore, a rotating shaft is rotatably connected inside the connecting seat, an L-shaped connecting rod is fixedly connected to the outer wall of the rotating shaft, a threaded seat is fixedly connected to one side of the outer wall of the L-shaped connecting rod, a threaded rod is threadedly connected inside the threaded seat, and a fixing component is provided at one end of the threaded rod.

[0009] Furthermore, the fixing component includes a V-shaped elastic clamping plate, which is rotatably connected to one end of the threaded rod, and a guide post is fixedly connected to the outer wall of the V-shaped elastic clamping plate.

[0010] Furthermore, the outer wall of the guide post slides inside the L-shaped connecting rod, and the guide post is used to guide the V-shaped elastic clamping plate.

[0011] Furthermore, the threaded rod passes through the interior of the L-shaped connecting rod to drive the V-shaped elastic clamping plate to move.

[0012] Furthermore, the V-shaped elastic clamping plate has a V-shaped design and can fit against the outer wall of the pipe through its own elastic deformation.

[0013] Furthermore, one end of the spring is fixedly connected inside the fixed ring, and the other end of the spring is fixedly connected inside the sealing ring.

[0014] Furthermore, the outer wall of the telescopic rod is slidably connected inside the fixed ring to guide the spring and the sealing ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the coordinated design of a fixed ring, spring, sealing ring, movable ring, screw, nut, and washer enables rapid installation and stable connection between the conveying pipe and the connecting seat. The spring pushes the sealing ring into the pre-set groove of the pipe, forming a tight seal and preventing leakage of the air-water mixture during cleaning, thus improving the safety and reliability of the cleaning operation. The fit design of the movable ring and the fixed ring, combined with the fixing method of the screw and nut, not only facilitates the extension and installation of the conveying pipe to meet the cleaning needs of pipes of different lengths, but also allows for flexible adaptation to various pipe diameters by adjusting the tightness of the nut, significantly improving the versatility and ease of operation of the device.

[0017] 2. In this utility model, the linkage mechanism based on the rotating shaft, L-shaped connecting rod, threaded rod, threaded seat, guide column, and V-shaped elastic clamping plate realizes the rapid positioning and firm fixation of the device and the pipeline. Pulling the L-shaped connecting rod to rotate around the rotating shaft to make it fit against the outer wall of the pipeline can quickly complete the initial positioning of the device. When the threaded rod is driven to rotate, the cooperation between the threaded seat and the guide column can ensure that the V-shaped elastic clamping plate moves smoothly towards the pipeline. The elastic clamping force realizes the adaptive fixation of pipelines of different materials, which not only avoids damage to the pipeline caused by rigid clamping, but also effectively counteracts the vibration generated by air and water pulses during the cleaning process, improves the stability and reliability of the device during operation, and provides strong support for efficient pipeline cleaning.

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a gas-water pulse pipeline cleaning device, including a connecting seat 1. A fixing ring 7 is fixedly connected to the bottom of the connecting seat 1, serving as a positioning reference for the top of the connecting seat 1 and providing radial installation positioning for the delivery pipe 2, ensuring that it coincides with the axis of the connecting seat 1. The delivery pipe 2 is arranged on the inner wall of the fixing ring 7. A rotating shaft 8 is fixedly connected to one end of the fixing ring 7, and a movable ring 9 is fixedly connected to the outer wall of the rotating shaft 8. The movable ring 9, which is sleeved on the outside of the delivery pipe 2, transmits locking force through the contact surface with the fixing ring 7, thereby achieving axial fixation between the delivery pipe 2 and the connecting seat 1. It can move along the axial direction of the delivery pipe 2 to adapt to different lengths. To extend installation requirements, a screw 10 is rotatably connected to the other end of the fixed ring 7. A nut 11 is fixedly connected to the outer wall of the screw 10. The screw 10 passes through the radial through hole of the movable ring 9 and is threadedly engaged with the nut 11. When the nut 11 is rotated, the movable ring 9 is pressed onto the fixed ring 7 by the washer 12, forming a mechanical locking structure to ensure the stability of the connection. By adjusting the tightness of the nut 11, the position of the movable ring 9 can be flexibly adjusted to adapt to various pipe diameters of the conveying pipe 2. The outer wall of the nut 11 is threadedly connected to the washer 12. The top of the connecting seat 1 is fixedly connected to the air-water pulse flusher body 13. A sealing component is provided on one side of the outer wall of the fixed ring 7.

[0027] The sealing assembly includes a fixing ring 3 and a sealing ring 6. The annular rubber seal, after being embedded in the groove of the connecting seat 1 and the groove of the delivery pipe 2, fills the gap through elastic deformation, preventing the gas-water mixture from leaking from the connection. The outer wall of the fixing ring 3 is fixedly connected to one side of the outer wall of the fixing ring 7. The sealing ring 6 is slidably connected to the inside of the fixing ring 3. A telescopic rod 4 is provided inside the sealing ring 6. A spring 5 is sleeved on the outer wall of the telescopic rod 4. The pre-compression elastic force pushes the sealing ring 6 to move towards the pipe connection, so that the sealing ring 6 is tightly embedded in the preset groove of the connecting seat 1 and the delivery pipe 2, forming an elastic sealing force, compensating for installation errors and maintaining a long-term sealing effect. One end of the spring 5 is fixedly connected to the inside of the fixing ring 3, and the other end of the spring 5 is fixedly connected to the inside of the sealing ring 6. The outer wall of the telescopic rod 4 is slidably connected to the inside of the fixing ring 3, which is used to guide the spring 5 and the sealing ring 6.

[0028] Specifically, the spring 5 pushes the sealing ring 6 into the pre-set groove inside the connecting seat 1 and the conveying pipe 2, which can form a tight seal, prevent the leakage of air-water mixture during the cleaning process, and improve the safety and reliability of the cleaning operation. The fit design of the movable ring 9 and the fixed ring 7, combined with the fixing method of the screw 10 and the nut 11, not only facilitates the extension and installation of the conveying pipe 2 to meet the cleaning needs of pipes of different lengths, but also allows for flexible adaptation to various pipe diameters by adjusting the tightness of the nut 11, which significantly improves the versatility and ease of operation of the device.

[0029] Reference Figure 1 , Figure 4 and Figure 5The connecting seat 1 is rotatably connected to a rotating shaft 14, which serves as the fulcrum for the rotation of the L-shaped connecting rod 15, allowing the L-shaped connecting rod 15 to swing around its center. The L-shaped connecting rod 15 is fixedly connected to the outer wall of the rotating shaft 14, with one end hinged to the outer wall of the connecting seat 1 via the rotating shaft 14. A threaded seat 16 is fixedly connected to one side of the outer wall of the L-shaped connecting rod 15, and a threaded rod 17 is threadedly connected inside the threaded seat 16. The rotational motion is converted into linear motion through threaded transmission, driving the threaded seat 16 to move axially. It cooperates with the guide post 19 to ensure the stability of the translation of the V-shaped elastic clamping plate 18 and avoid offset or jamming. One end of the threaded rod 17 is provided with a fixing component, which includes the V-shaped elastic clamping plate 18, made of elastic metal material, with a wave-shaped anti-slip texture on the inner side. When the V-shaped structure moves towards the pipeline under the drive of the threaded rod 17, it adapts to the pipeline with different outer diameters through elastic deformation, providing a stable clamping force. The V-shaped elastic clamping plate 18 is rotatably connected to one end of the threaded rod 17. The outer wall of the V-shaped elastic clamping plate 18 is fixedly connected to the guide post 19. The outer wall of the guide post 19 slides inside the L-shaped connecting rod 15. The guide post 19 is used to guide the V-shaped elastic clamping plate 18. The threaded rod 17 passes through the interior of the L-shaped connecting rod 15 and is used to drive the V-shaped elastic clamping plate 18 to move. The V-shaped elastic clamping plate 18 has a V-shaped design and can fit against the outer wall of the pipeline through its own elastic deformation.

[0030] Specifically, pulling the L-shaped connecting rod 15 to rotate around the rotating shaft 14 to fit against the outer wall of the pipe can quickly complete the initial positioning of the device; when driving the threaded rod 17 to rotate, the cooperation between the threaded seat 16 and the guide post 19 can ensure that the V-shaped elastic clamping plate 18 moves smoothly towards the pipe. The elastic clamping force can achieve adaptive fixation for pipes of different materials, which not only avoids damage to the pipe caused by rigid clamping, but also effectively counteracts the vibration generated by air and water pulses during the cleaning process, improving the stability and reliability of the device during operation, and providing strong support for efficient pipe cleaning.

[0031] Working principle: When the air-water pulse pipeline cleaning device is needed, first place the delivery pipe 2 on one side of the outer wall of the fixed ring 7 and fit it with the fixed ring 3. Then, the sealing ring 6 is pushed into the groove inside the connecting seat 1 and the delivery pipe 2 by the spring 5, so that they fit tightly and achieve a seal. Next, pull one end of the movable ring 9 to fit with one end of the fixed ring 7. Then, move the screw 10 to the inside of one end of the movable ring 9. Then, rotate the nut 11 to drive the washer 12 to fit tightly with the movable ring 9 and fix the movable ring 9. This realizes the installation connection between the connecting seat 1 and the delivery pipe 2, realizes the extension of the delivery pipe 2, and cleans the pipeline respectively.

[0032] In addition, before use, the bottom of the connecting seat 1 is first inserted into the pipe, and then the L-shaped connecting rod 15 is pulled to rotate around the rotating shaft 14, so that the outer side of the L-shaped connecting rod 15 moves to the outer wall of the pipe. Then the threaded rod 17 is driven to rotate. With the thread relationship between the threaded rod 17 and the threaded seat 16, and the guidance of the guide post 19, the threaded rod 17 drives the V-shaped elastic clamping plate 18 to move towards the pipe, so that the V-shaped elastic clamping plate 18 fits and is fixed to the pipe.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
