Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cleaning devices, and in particular relates to a pipeline cleaning device for water conservancy projects. Background Art

[0002] During the construction of water conservancy projects, a large number of pipes are laid for the transportation of resources. During the transportation process, a large amount of silt and dirt will accumulate in the pipes, and the inner wall of the pipe is in a humid environment for a long time. It is also easy for algae and other floating objects to stick to the inner wall of the pipe. Therefore, the pipes need to be cleaned regularly after long-term use.

[0003] Existing pipeline cleaning devices usually flush the pipeline manually using high-pressure water, but some debris is difficult to flush down. Since the pipeline is long, it is difficult to brush it all off with a brush, which easily leads to incomplete pipeline cleaning. When the pipeline is used later, it is easier for debris to accumulate in places that have not been cleaned, affecting the use of the pipeline. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a pipeline cleaning device for water conservancy projects, and the technical solution adopted is as follows:

[0005] A pipeline cleaning device for water conservancy engineering comprises a nozzle, a mounting frame is connected to the rear end of the nozzle through a connecting rod, an extension pipe is arranged at the rear end of the mounting frame, the front end of the extension pipe passes through the mounting frame and is connected to the connecting rod, and a scraping mechanism is installed on any edge surface of the mounting frame;

[0006] The scraping mechanism includes a support plate fixed to the outside of the mounting frame, a bow frame is provided on the outside of the support plate, two telescopic rods are connected to the inside of the bow frame, one end of the telescopic rod passes through the mounting frame and is slidably connected to the mounting frame; a spring is sleeved on the outside of the telescopic rod between the support plate and the bow frame, and a roller in contact with the inner wall of the pipe is provided in the middle position of the outer side of the bow frame, and a scraper strip is embedded on the outer side of the bow frame and at the upper and lower positions of the roller.

[0007] Furthermore, the mounting frame adopts a square column or a regular polygonal column, and the scraping mechanisms located on different edges of the mounting frame are arranged in sequence from one end connected to the nozzle to the other end, and are at different horizontal positions, which can avoid affecting the work of the scraping mechanisms due to the cross-setting of the telescopic rods when they are at the same horizontal position.

[0008] Furthermore, a convex plate is provided on the outer side of one end of the telescopic rod passing through the mounting frame, and a telescopic groove for the convex plate to be embedded and slid is provided inside the mounting frame, which can limit the moving distance of the telescopic rod.

[0009] Furthermore, the bow frame is a plastic plate with an arc-shaped structure and has a certain elastic deformation range. Under the action of the spring, the bow frame can be pushed to the junction with the inner wall of the pipe. When the curvature of the inner diameter of the pipe is different from the curvature of the bow frame, the bow frame will undergo a certain deformation under the thrust of the spring, so that the scraper bar on the outside of the bow frame can fully contact the inner wall of the pipe with different inner diameters. When the operator pulls through the extension pipe or the external water pipe, the mounting frame can move inside the pipe, so that the scraper bar in the scraping mechanism can scrape off the dirt on the inner wall of the pipe.

[0010] Furthermore, the roller adopts a conical structure with small ends and a large middle. The roller can prevent the bow frame from contacting the inner wall of the pipe, reduce friction, and enable the mounting frame and the scraping mechanism to move more easily in the pipe.

[0011] Furthermore, the scraper strip is a rubber strip, and the outer edge of the scraper strip protruding from the bow frame is in the same plane as the outer edge of the roller. After the roller presses against the inner wall of the pipe, the scraper strip can just contact the inner wall of the pipe. While being able to scrape off debris on the inner wall of the pipe, it can also reduce the friction caused by the too close contact between the scraper strip and the pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model arranges a scraping mechanism on the rear side of the nozzle, and the nozzle can be used for the first cleaning to flush down some debris or green algae in the inner wall of the pipe, and soak the dirt that has not been flushed down, so that the scraping bar in the scraping mechanism can perform the second cleaning on it and scrape it clean. When working, it is only necessary to push the device as a whole back and forth, and the device can be rotated during the pushing, so that the cleaning effect achieved is better and more thorough, and the normal use of the pipe in the later stage can be guaranteed.

[0014] The utility model can reduce the contact between the bow frame and the inner wall of the pipeline and reduce friction by installing a tapered roller on the outer side of the bow frame, so that the mounting frame together with the scraping mechanism can move more easily in the pipeline, and the scraping strip protruding from the outer edge of the bow frame and the outer edge of the roller are in the same plane, so that after the roller abuts against the inner wall of the pipeline, the scraping strip can also contact the inner wall of the pipeline, so that the inner wall of the pipeline can be fully scraped and cleaned.

[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] As attached Figure 1-7 As shown; a pipeline cleaning device for water conservancy projects, including a nozzle 1, a mounting frame 3 with a square column structure is connected to the rear end of the nozzle 1 through a connecting rod 2, an extension pipe 4 is provided at the rear end of the mounting frame 3, the front end of the extension pipe 4 passes through the mounting frame 3 and is connected to the connecting rod 2, the tail end of the extension pipe 4 is connected to a water pipe, and a water pump is used to provide water flow that can be sprayed out to impact the inside of the pipeline 9 for the nozzle 1 at the front end.

[0028] A plurality of scraping mechanisms are sequentially installed in the mounting frame 3 from one end connected to the nozzle 1 toward the other end. The scraping mechanisms are respectively installed in different edges of the mounting frame 3. The number of the scraping mechanisms is equal to the number of edges of the mounting frame 3. The length of the mounting frame 3 is the sum of the thicknesses of all the mounting frames 3 so that the mounting frames 3 can be arranged in sequence and installed in different edges.

[0029] The scraping mechanism includes a support plate 5 fixed to the outside of the mounting frame 3, a bow frame 6 is provided on the outside of the support plate 5, and two telescopic rods 7 are connected to the inner side of the bow frame 6. One end of the telescopic rod 7 passes through the mounting frame 3 and is slidably connected to the mounting frame 3; a convex plate is provided on the outside of one end of the telescopic rod 7 passing through the mounting frame 3, and a telescopic groove 31 for the convex plate to be embedded and slid is provided inside the mounting frame 3, which can limit the moving distance of the telescopic rod 7.

[0030] A spring 8 is mounted on the outside of the portion of the telescopic rod 7 between the support plate 5 and the bow frame 6. The bow frame 6 is a plastic plate with an arc-shaped structure, and a roller 61 in contact with the inner wall of the pipe 9 is provided in the middle position of the outer side of the bow frame 6. A scraper bar 62 is embedded on the outer side of the bow frame 6 and at the upper and lower positions of the roller 61. The bow frame 6 can be pushed by the spring 8 so that the scraper bar 62 on the outside of the bow frame 6 is in full contact with the inner wall of the pipe 9. When the operator pulls through the extension pipe 4 or the external water pipe, the mounting frame 3 can move inside the pipe 9, so that the scraper bar 62 in the scraping mechanism scrapes off the dirt on the inner wall of the pipe.

[0031] The roller 61 is a conical wheel with small ends and a large middle. The roller 61 can reduce the contact between the bow frame 6 and the inner wall of the pipe 9, reduce friction, and enable the mounting frame 3 together with the scraping mechanism to move more easily in the pipe 9. The scraper strip 62 protrudes from the outer edge of the bow frame 6 and is in the same plane as the outer edge of the roller 61. The scraper strip 62 is a rubber strip, so after the roller 61 is against the inner wall of the pipe 9, the scraper strip 62 can also fully contact the inner wall of the pipe 9.

[0032] The usage process is as follows: when the pipe 9 needs to be cleaned, just insert one end of the nozzle 1 of the device into the pipe 9 first, and then connect the extension tube 4 at the tail end of the device to the water pipe, so that the water flows out from the outside of the nozzle 1. The nozzle 1 adopts a rotating nozzle, which can flush the inner wall of the pipe 9 while moving.

[0033] After the nozzle 1 is inserted into the pipe 9, the mounting frame 3 and the scraping mechanism outside the mounting frame 3 need to be inserted into the pipe 9 in turn. Because the bow frame 6 in the scraping mechanism will remain in an extended state under the action of the spring 8, manual assistance is required to compress the bow frame 6 outside the mounting frame 3 to be smaller than the inner diameter of the pipe 9 when inserting into the pipe 9. Since there are multiple scraping mechanisms, one hand can be used to compress and the other hand can be used to push the multiple scraping mechanisms into the interior of the pipe 9 in turn.

[0034] After the scraping mechanism is inserted into the pipe 9, under the action of the spring 8, the scraping bar 62 in the scraping mechanism will be in close contact with the inner wall of the pipe 9. When the mounting frame 3 is pulled by the extension pipe 4 or the external water pipe, the scraping bar 62 in the scraping mechanism will be able to scrape the inner wall of the pipe 9.

[0035] Since the diameters of the pipes 9 to be cleaned are different, and the size of the bracket 6 is affected, only when cleaning pipes 9 of a specific diameter, the bracket 6 in each scraping mechanism can be as shown in the attached figure. Figure 4 As shown, the mounting frame 3 is formed into a circle, and when cleaning the pipeline 9, there is no need to rotate the mounting frame 3, and only need to push it back and forth.

[0036] When the brackets 6 in the scraping mechanisms are not combined into a circle in the pipe 9, there will be dead zones in the adjacent scraping mechanisms. In view of this situation, the cleaning device is rotated while being pushed back and forth to clean the dead zones.

[0037] The rotation of the cleaning device can be achieved by rotating the extension tube 4 or the external water pipe, and the movement of the cleaning device can be achieved by pulling the extension tube 4 or the external water pipe.

[0038] Embodiment 2:

[0039] As attached Figure 8 As shown; the difference from Example 1 is that the shape of the mounting frame 3 is different. In this embodiment, the mounting frame 3 adopts a regular polygonal prism structure, and a scraping mechanism having an equal number of edges of the mounting frame 3 is provided on the outer side of the mounting frame 3.

[0040] The more facets the mounting frame 3 has, the more scraping mechanisms are provided, and the smaller the dead zone area between corresponding adjacent scraping mechanisms is. Considering the comprehensive factors of weight and cost, the mounting frame 3 can best be a regular hexagonal prism.

[0041] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
