Description

Technical Field

[0001] This utility model relates to the field of condenser descaling technology, and in particular to a pipeline cleaning device for condensers. Background Technology

[0002] The cooling water system of a power plant is an open circulating water system. The condenser in the cooling water system is usually made of stainless steel. As the water evaporates and dries, some of the less soluble calcium salts will precipitate out of the water and form scale.

[0003] Therefore, a descaling device for a power plant condenser, disclosed in CN214892833U, has equidistantly spaced springs fixedly connected to the circumferential sidewall of a rotating shaft. These springs are all fixedly connected to a cleaning brush to facilitate cleaning the inner wall of the pipe. When the cleaning brush penetrates the inner wall of the pipe, the uneven surface caused by scale buildup causes the springs to extend and retract, pulling the cleaning brush to adapt to the unevenness of the pipe's interior. This facilitates cleaning the inner wall of the pipe. In use, the servo motor is turned on, driving the screw to rotate. The screw drives the screw sleeve to slide along the groove, which in turn drives the cleaning mechanism to reciprocate, thus achieving multiple cleanings of the inner wall of the pipe.

[0004] However, since the cleaning brush of this device has a fixed size, it may not be able to make good contact with the inner wall of the pipe if the pipe diameter is too different when cleaning pipes of different diameters, thus affecting the cleaning effect. Utility Model Content

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1-5 As shown, a pipe cleaning device for a condenser includes a base 1, on which a lead screw 4 is mounted. One end of the lead screw 4 is fixedly connected to a cleaning mechanism for cleaning pipes. The cleaning mechanism includes a support sleeve 11 fixedly connected to the lead screw 4. A plurality of cleaning blocks 13 arranged in a circular array are slidably connected through the side of the support sleeve 11. A connecting ball 18 is provided at the other end of the cleaning block 13. A plurality of limiting rods 16 arranged in a circular array are fixedly connected to one side of the inside of the support sleeve 11. A frustum-shaped sleeve 15 driven to slide by a driving component is provided inside the support sleeve 11. A plurality of limiting grooves 17 are opened inside the frustum-shaped sleeve 15 and slidably connected to the limiting rods 16. The outer side of the frustum-shaped sleeve 15 abuts against a plurality of connecting balls 18. The driving component is preferably an electric telescopic rod. The method of use is that the fixed end of the electric telescopic rod is fixed to one side of the inside of the support sleeve 11, and the telescopic end is fixed to one end of the frustum-shaped sleeve 15.

[0020] In this technical solution, the working principle of the cleaning mechanism is as follows: When it is necessary to clean pipes of different diameters, the driving component drives the frustum sleeve 15 to slide inside the support sleeve 11. Since the outer side of the frustum sleeve 15 is a conical surface and abuts against the connecting ball 18, it will exert different degrees of compression on the connecting ball 18 during its sliding process. After the connecting ball 18 is compressed, it will push the associated cleaning block 13 to move outward of the support sleeve 11. Since the cleaning blocks 13 are distributed in a ring array, multiple cleaning blocks 13 can expand outward at the same time, thereby adapting to pipes of different inner diameters.

[0021] Meanwhile, the limiting rod 16 inside the support sleeve 11 is slidably connected to the limiting groove 17 of the frustum sleeve 15. This structure guides and limits the sliding of the frustum sleeve 15, ensuring that the frustum sleeve 15 can only slide stably along the direction of the limiting rod 16, avoiding deviation or shaking during the sliding process, and ensuring the stability and accuracy of the expansion or contraction of the cleaning block 13.

[0022] like Figure 5 As shown, the cleaning block 13 and the connecting ball 18 are fixedly connected to the spring rod 19. The fixed end of the spring rod 19 is fixed to the connecting ball 18, and the telescopic end of the spring rod 19 is fixed to the cleaning block 13. A compression spring 14 is fixedly connected between the outer side of the fixed end of the spring rod 19 and the support sleeve 11.

[0023] In this technical solution, the spring rod 19 connects the cleaning block 13 and the connecting ball 18. Its extensibility allows the cleaning block 13 to elastically expand and contract to a certain extent according to the unevenness of the inner wall of the pipe when it comes into contact with the inner wall of the pipe, so as to avoid rigid collision between the cleaning block 13 and the inner wall of the pipe, while ensuring that the cleaning block 13 always keeps in contact with the inner wall of the pipe, thus ensuring thorough cleaning.

[0024] In addition, when this device is in use, the compression spring 14 is always in a contracted state. When the cleaning block 13 moves outward during the sliding of the frustum sleeve 15, the compression spring 14 can only be in a more contracted state. The purpose is that when the cleaning structure encounters a pipe with a smaller diameter, the driving member drives the frustum sleeve 15 to retract. At this time, under the action of the restoring force of the compression spring 14, the cleaning block 13 is also retracted.

[0025] like Figure 1 As shown, a groove 2 is provided on one side of the top of the base 1. A slide block 3 is slidably connected in the groove 2. A motor 9 is fixedly connected to the slide block 3. The main shaft of the motor 9 is fixed to the other end of the lead screw 4. A threaded sleeve 5 is fixedly connected to the base 1. The threaded sleeve 5 is threadedly connected to the lead screw 4.

[0026] In this technical solution, the motor 9 is fixed on the slide 3, and its main shaft is connected to the lead screw 4, providing power for the rotation of the lead screw 4. When the motor 9 starts, the lead screw 4 rotates accordingly. Since the lead screw 4 is threadedly connected to the threaded sleeve 5 on the base 1, the threaded sleeve 5 will generate a reaction force on the lead screw 4 during its rotation, causing the lead screw 4 to move along its own axial direction while rotating. The movement of the lead screw 4 will drive the slide 3, which is fixedly connected to it, to slide in the slide groove 2. The slide groove 2 guides the sliding of the slide 3, ensuring the stable movement of the slide 3 and the motor 9. The cleaning mechanism connected to the other end of the lead screw 4 will penetrate into the inside of the pipe as the lead screw 4 rotates and moves axially, and advance forward while rotating, so that the cleaning block 13 can perform spiral cleaning on the inner wall of the pipe, improving the comprehensiveness and efficiency of cleaning.

[0027] like Figure 1 and Figure 3 As shown, two storage rods 8 for supporting pipes are provided on the other side of the top of the base 1. A bidirectional threaded rod 12 that is rotatably connected to the base 1 is threaded between the two storage rods 8. A guide groove 10 that is slidably connected to the bottom of the storage rods 8 is provided on the top of the base 1. A motor 9 is also fixedly installed on one side of the base 1. The main shaft of the motor 9 located on one side of the base 1 is fixed to one end of the bidirectional threaded rod 12.

[0028] In this technical solution, the two storage rods 8 serve as support components for the pipeline, and their relative positions can be adjusted by the bidirectional threaded rod 12. When the motor 9 starts, it drives the bidirectional threaded rod 12 to rotate. Since both storage rods 8 are threadedly connected to the bidirectional threaded rod 12, and the thread direction of the bidirectional threaded rod 12 is symmetrical, the two storage rods 8 will slide closer or further apart along the guide groove 10 during the rotation of the bidirectional threaded rod 12. The guide groove 10 guides and limits the sliding of the storage rods 8, ensuring that the storage rods 8 maintain a stable movement trajectory during the adjustment process and avoiding deviation.

[0029] By adjusting the distance between the two storage rods 8, condenser pipes of different diameters can be adapted, ensuring that the pipes remain stable when placed on the storage rods 8, and that the center of the pipes is aligned with the center of the cleaning structure.

[0030] like Figure 1 As shown, a hydraulic rod 7 is fixedly installed at the tail end of the base 1, and a push plate 6 for pressing the pipe is fixedly connected to the telescopic end of the hydraulic rod 7.

[0031] In this technical solution, after the pipe is placed on the two storage rods 8 and the position is adjusted, the hydraulic rod 7 can drive the push plate 6 to move towards the pipe; after the push plate 6 contacts the end of the pipe, it will apply a certain pressure to the pipe, pressing the other end of the pipe against the threaded sleeve 5, thereby pressing the pipe onto the storage rods 8.

[0032] The method of using this utility model is as follows: First, according to the diameter of the pipe to be cleaned, start the motor 9 on one side of the base 1 to drive the bidirectional threaded rod 12 to rotate, so that the two storage rods 8 move closer or further apart along the guide groove 10 to fit the pipe. Place the pipe on the storage rods 8, and start the hydraulic rod 7 to push the push plate 6 to press the pipe. Then, drive the frustum sleeve 15 to slide in the support sleeve 11 through the driving component. Utilize the abutment of the frustum sleeve 15 and the connecting ball 18, combined with the action of the spring rod 19 and the compression spring 14, to adjust the expansion degree of the cleaning block 13 to fit the inner diameter of the pipe. Then, start the motor 9 on the slide 3 to drive the lead screw 4 to rotate. Under the action of the threaded sleeve 5, the lead screw 4 rotates and moves axially, while driving the slide 3 to slide in the slide groove 2, so that the cleaning mechanism goes deeper into the pipe with the lead screw 4. The cleaning block 13 cleans the inner wall of the pipe during the rotation and advancement process.

[0033] The wiring diagrams of the drive unit, hydraulic rod 7, and motor 9 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the drive unit, hydraulic rod 7, and motor 9 will not be explained in detail. Among them, the motor 9 is preferably a servo motor.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
