Description

Technical Field

[0001] The utility model relates to the technical field of pipeline silt cleaning, in particular to a non-excavation pipeline construction silt cleaning device. Background Technique

[0002] Non-excavation refers to a new construction technology that uses various geotechnical drilling and excavation equipment and technical means to lay, replace, and repair various underground pipelines, including cleaning the inside of the pipeline, especially cleaning the silt that enters the inside of the pipeline.

[0003] After retrieval

[0004] A non-excavation pipeline construction silt cleaning device, with the publication number: CN219887132U. When cleaning the silt in the pipeline, the device is placed in the pipeline to be cleaned, the high-pressure pump is started to pump out the water in the water storage tank and spray it out from the nozzle. The sprayed high-pressure water flow flushes the bottom of the pipe wall of the pipeline to be cleaned, so that the silt at the bottom of the pipe is separated from the pipe wall and diluted, facilitating the silt to flow from the pipeline to be cleaned into the inspection well at the end of the pipeline to be cleaned, realizing the cleaning of the pipeline to be cleaned. At the same time, the driving mechanism drives the bottom wheels to rotate, thereby driving the water storage tank to move along the pipeline direction, and further driving the nozzle to move along the pipeline direction. During the movement of the water storage tank, the nozzle always flushes the pipe wall directly below itself. When the water storage tank moves along the pipeline to be cleaned, the scraping plate comes into contact with the bottom silt, which can push the bottom silt, causing the silt to break away from its original position. The separated silt flows into the inspection well at the end of the pipeline to be cleaned along with the diluted slurry of the silt in the pipeline.

[0005] However, the existing technology uses the method of placing a water storage tank in the pipeline to achieve silt cleaning. However, the sizes of pipelines for different purposes are different, and the thicknesses of the deposited silt are also different. Therefore, the water storage tank will be restricted in use. There may be a situation where the volume of the water storage tank is too large to enter a smaller pipeline, or the pipeline size is too large. Even if the water storage tank enters the pipeline in time, the water stored in it will be quickly consumed, and it is necessary to frequently take out the pipeline and add water to the water storage tank. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a non-excavation pipeline construction silt cleaning device.

[0007] To achieve the above object, the utility model adopts the following technical scheme: A non-excavation pipeline construction sludge cleaning device, including a water storage tank and a nozzle. An electric winding reel is installed at the water outlet of the water storage tank. A water pipe for connecting the water outlet of the water storage tank and the nozzle is wound on the electric winding reel. The nozzle is rotatably connected to one end of the water pipe, and an electric push rod is fixedly connected inside the nozzle. The outer wall of the nozzle is hollowed out, and a water spray pipe is in clearance fit with the hollowed-out part.

A connecting plate is fixedly connected to the shaft surface of the rotating shaft. The connecting plate is arranged in a U shape and is clamped on the connecting frame. The side of the connecting plate is arranged in a column shape and is slidably connected to the inner wall of the connecting frame.

[0008] Preferably, a spiral ring threadedly connected to one end of the water pipe is rotatably connected to the water inlet of the nozzle. A turbine is rotatably connected inside the spiral ring, and one end of the turbine shaft extends to be fixed to the inner wall of the nozzle.

[0009] Preferably, an elastic waterproof cloth is fixedly connected between the outer wall of the water spray pipe and the inner wall of the hollowed-out part of the nozzle.

[0010] Preferably, a cutting ring is further arranged on the outer wall of the nozzle. An installation rail is fixedly connected to the inner wall of the cutting ring. A plurality of electric wire reels are detachably connected inside the installation rail.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are as follows.

[0015] 1. In the utility model, by setting an external water storage tank, the water in the water storage tank is transported to the nozzle through a water pipe.

Detailed Embodiment

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Such as Figures 1-6As shown, a non-excavation pipeline construction sludge cleaning device includes a water storage tank 1 and a nozzle 5. An electric winding reel 2 is installed at the water outlet of the water storage tank 1. A water pipe 3 for connecting the water outlet of the water storage tank 1 and the nozzle 5 is wound on the electric winding reel 2. The water storage tank 1 is externally placed by being loaded on a vehicle, which is convenient for filling a large amount of water. And a water pump is connected between the water outlet of the water storage tank 1 and the other end of the water pipe 3. The water outlet of the water pump and the other end of the water pipe 3 are connected by a rotary joint. The rotary joint is installed at the center of the end face of the electric winding reel 2. Therefore, the water in the water storage tank 1 can be pumped into the nozzle 5 along the water pipe 3 by the water pump, and the nozzle 5 can move forward or backward in the pipeline by rotating and releasing or winding the water pipe 3 by the electric winding reel 2:

[0027] The nozzle 5 is rotatably connected to one end of the water pipe 3, and an electric push rod 13 is fixedly connected inside the nozzle 5. The outer wall of the nozzle 5 is hollowed out, and a water spray pipe 9 is in clearance fit with the hollowed-out part. The water entering the nozzle 5 sprays out along a plurality of water spray pipes 9 at a relatively high flow rate and acts on the inner wall of the pipeline. And along with the rotation of the nozzle 5, a plurality of sprayed water columns rotate in a spiral shape. Also as Figure 4 shown, the water outlet of the water spray pipe 9 faces the direction of the water pipe 3. Therefore, the water column sprayed backward generates a forward thrust on the nozzle 5, realizing the forward movement of the nozzle 5 along the inner wall of the pipeline. Moreover, during the forward movement of the nozzle 5, the water spray pipe 9 swings obliquely by using the gap between the water spray pipe 9 and the nozzle 5 to adjust the length of the water column sprayed by the nozzle 5 from the inner wall of the pipeline, and then adjust the impact force of the sprayed water column acting on the sludge, which is convenient for dealing with relatively stubborn sludge:

[0028] An elastic waterproof cloth 11 is fixedly connected between the outer wall of the water spray pipe 9 and the inner wall of the hollowed-out part of the nozzle 5. The provided elastic waterproof cloth 11 ensures that the water spray pipe 9 can swing smoothly and also ensures that the water in the nozzle 5 will not spray out along the gap between the water spray pipe 9 and the nozzle 5. A rotating shaft 16 corresponding to the positions of a plurality of water spray pipes 9 one by one and fixedly connected to one end of the water spray pipe 9 is rotatably connected to the inner wall of the nozzle 5. The electric push rod 13 is located at the center line of the nozzle 5, and a connecting frame 14 is fixedly connected to the telescopic end of the electric push rod 13. A connecting plate 15 is fixedly connected to the shaft surface of the rotating shaft 16. The connecting plate 15 is arranged in a U shape and is clamped on the connecting frame 14. The side of the connecting plate 15 is arranged in a column shape and is slidably connected to the inner wall of the connecting frame 14. In this solution, the electric push rod 13 used adopts wireless control technology, and the electric push rod 13 can be telescopically extended smoothly by installing a waterproof battery inside the nozzle 5. Therefore, by telescoping the electric push rod 13, the connecting frame 14 at its telescopic end can be moved. By using the contact between the connecting frame 14 and the side of the connecting plate 15, the connecting plate 15 is pushed to swing around the rotating shaft 16. And because the connecting plate 15 is fixed to the rotating shaft 16, the rotating shaft 16 can rotate along with the swing of the connecting plate 15, and then the water spray pipe 9 fixed to the rotating shaft 16 swings.

[0029] In order to realize that the nozzle 5 can rotate and emit a spiral water column to flush the silt in the pipeline: the water inlet of the nozzle 5 is rotatably connected to a spiral ring 10 threadedly connected to one end of the water pipe 3, and a turbine 12 is rotatably connected inside the spiral ring 10. One end of the turbine 12 axle extends to be fixed to the inner wall of the nozzle 5. Before water passes through the water pipe 3 and enters the nozzle 5, it first passes through the spiral ring 10, and the turbine 12 inside the spiral ring 10 can rotate smoothly under the flushing action of the water flow, and drive the nozzle 5 to rotate relative to the spiral ring 10.

[0030] In order to prevent the silt from sticking to the inner wall of the pipe and being unable to be flushed clean: a cutting ring 4 is also provided on the outer wall of the nozzle 5, and a mounting rail 6 is fixedly connected to the inner wall of the cutting ring 4, and a plurality of electric wire reels 7 are detachably connected to the mounting rail 6. The wire wound in the electric wire reel 7 extends toward the nozzle 5 and is fixedly connected to an internal threaded ring 17 sleeved on the nozzle 5. An external threaded ring 18 threadedly connected to the internal threaded ring 17 is rotatably connected to the outer wall of the nozzle 5, and bolts 8 symmetrically distributed about the internal threaded ring 17 are threadedly connected to the outer side of the external threaded ring 18, and the spacing between the two bolts 8 on the external threaded ring 18 is equal to the width of the internal threaded ring 17, the electric wire reel 7 is slidably connected to the inner wall of the mounting rail 6, and bolts 8 are also installed between the electric wire reel 7 and the mounting rail 6. In this scheme, the electric wire reel 7 is fixed to the corresponding position of the mounting rail 6 by bolts 8, so that Several electric cable reels 7 are distributed in a circular array, and the position installation and fixing are achieved by threaded connection of the internal thread ring 17 and the external thread ring 18. Then, under the traction of the center line of several electric cable reels 7, the nozzle 5 drives the cutting ring 4 to move in the pipeline. By selecting a cutting ring 4 with the same inner diameter as the pipeline, the cutting ring 4 removes the sludge before the nozzle 5 flushes the sludge, so that the sludge is separated from the inner wall of the pipeline, and by adjusting the release length of the electric cable reel 7 at different positions, the internal thread ring 17 and the nozzle 5 can be driven to move in the cutting ring 4, that is, the relative position of the nozzle 5 and the sludge can be adjusted. By adjusting the position of the nozzle 5 and the sludge, the water spray pipe 9 is close to the position of the sludge, that is, the water column sprayed by the water spray pipe 9 flushes the sludge surface with a shorter distance and greater impact force, which is convenient for targeting stubborn sludge:

[0031] In addition, the two bolts 8 arranged on the external thread ring 18 in this solution can prevent the internal thread ring 17 from rotating on the external thread ring 18 and falling off, and the rotational connection between the external thread ring 18 and the nozzle 5 can ensure that the nozzle 5 can rotate in the cutting ring 4 without causing the cutting ring 4 to rotate.

[0032] Working principle: Use a vehicle to transport the water storage tank 1 filled with water to the corresponding location. Use a water pump to pump the water in the water storage tank 1 along the water pipe 3 into the nozzle 5, and then spray it out in a spiral manner through the turbine 12 and the water spray pipe 9. Then, use the electric winding reel 2 to release the water pipe 3. Use the spiral water flow to push the nozzle 5 and the cutting ring 4 to move inside the pipeline. During the movement, use the cutting ring 4 to separate the silt from the inner wall of the pipeline, and then use the sprayed spiral water column to wash the separated silt. The silt is mixed with the sprayed water to form a thinner slurry and flows out of the pipeline.

[0033] The wiring diagrams of the electric winding reel 2, the electric cable reel 7 and the electric push rod 13 in the present utility model belong to the

[0034] common general knowledge in the field. Their working principles are already well-known technologies. Select appropriate models according to actual use. Therefore, the control methods and wiring arrangements of the electric winding reel 2, the electric cable reel 7 and the electric push rod 13 will not be explained in detail.

[0035] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
