Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, and in particular to a water conservancy pipeline dredging device. Background Technology

[0002] In the field of water conservancy engineering, water pipelines play a vital role, such as for irrigation and urban water supply. However, with the increase of service time and the influence of the operating environment, silt often accumulates inside water pipelines. Silt may come from various factors such as sedimentation in the water source and impurities produced by pipeline corrosion. The accumulation of silt will gradually reduce the effective water flow cross-section of the pipeline, leading to increased water flow resistance.

[0003] Traditional manual dredging methods are not only inefficient, but also difficult to operate on pipes with small diameters or large burial depths, as manual access is challenging. Most mechanical dredging equipment is designed for pipes of specific diameters, requiring different models when dealing with pipes of different diameters, which increases equipment costs and dredging time. For example, some dredging tools based on scraping principles have fixed dimensions and are difficult to adapt to pipes with large diameter variations. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water conservancy pipeline dredging device.

[0005] This utility model is achieved using the following technical solution: a water conservancy pipeline dredging device, comprising a support ring seat. A partition plate is fixedly connected to the inner wall of the support ring seat, a water supply pipe is fixedly connected inside the partition plate, a main high-pressure nozzle is fixedly connected to one end of the water supply pipe, several auxiliary high-pressure nozzles are fixedly connected to the surface of the water supply pipe, a protective sleeve is fixedly connected to the outer surface of the support ring seat, an electric push rod is fixedly connected to the inner wall of the protective sleeve, and a movable wheel is fixedly connected to the top end of the electric push rod.

[0006] Through the above technical solution, the device, with its main and auxiliary high-pressure nozzles, can effectively remove silt from pipelines. Furthermore, the combination of the electric push rod and movable wheels allows the device to adapt to pipelines of different diameters, improving its applicability. Operation is relatively simple and requires no complex adjustments.

[0007] As a further improvement to the above scheme, the number of auxiliary high-pressure nozzles is set to several, and the several auxiliary high-pressure nozzles are evenly distributed in a circumferential array on the outer surface of the water supply pipe.

[0008] The above technical solution ensures the comprehensiveness of sludge removal by evenly distributed secondary high-pressure nozzles, avoiding incomplete sludge removal in certain areas and improving the sludge removal effect.

[0009] As a further improvement to the above solution, the number of movable wheels is set to three, and the three movable wheels are evenly distributed in a circular array on the outer surface of the support ring seat.

[0010] The above technical solutions enhance the stability of the device's movement within the pipeline and also play an important role in adapting to different pipe diameters.

[0011] As a further improvement to the above solution, a pipe joint is fixedly connected to the surface of the water supply pipe.

[0012] Through the above technical solution, the existence of the pipe joint facilitates the connection between the device and the external pump equipment, enabling the water supply system to smoothly provide the required high-pressure water flow to the sludge removal device.

[0013] As a further improvement to the above solution, a push rod is fixedly connected to the surface of the water pipeline.

[0014] Through the above technical solution, the prop rod can ensure that the water pipeline and the nozzles on it move in an orderly manner inside the pipeline, thereby cleaning the silt in different locations inside the pipeline and expanding the scope of silt removal.

[0015] As a further improvement to the above solution, a hydraulic rod is fixedly connected to the surface of the push rod, and an outer sleeve is provided on the surface of the hydraulic rod.

[0016] Through the above technical solutions, the design of the hydraulic rod and outer sleeve makes the process of pushing the support rod to move the water pipeline into the pipeline more stable and controllable, thereby improving the accuracy and efficiency of sludge removal work.

[0017] As a further improvement to the above solution, the hydraulic rod is fixedly connected to the inner wall of the outer sleeve.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention features an electric push rod and three movable wheels arranged in a circular array. When dealing with pipes of different diameters, activating the electric push rod adjusts the extension or retraction position of the movable wheels, allowing them to contact the inner wall of the pipe and move. Once the electric push rod is deactivated, the support ring seat can move stably within pipes of varying diameters. This design enables the effective application of the desilting device in pipes of various diameters and ensures the smooth removal of sludge by the high-pressure water jet from the nozzle. This significantly enhances the applicability of the device, making it widely applicable to desilting operations in pipes of various diameters. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment of a water conservancy pipeline sludge removal device includes a support ring seat 1. A partition plate 2 is fixedly connected to the inner wall of the support ring seat 1. A water supply pipe 3 is fixedly connected inside the partition plate 2. A main high-pressure nozzle 4 is fixedly connected to one end of the water supply pipe 3. Several auxiliary high-pressure nozzles 5 are fixedly connected to the surface of the water supply pipe 3. A protective sleeve 6 is fixedly connected to the outer surface of the support ring seat 1. An electric push rod 7 is fixedly connected to the inner wall of the protective sleeve 6. A movable wheel 8 is fixedly connected to the top of the electric push rod 7. The main high-pressure nozzle 4 and auxiliary high-pressure nozzles 5 are connected to the water supply pipe 3. The water supply pipe 3 receives water from an external pump device connected to a pipe joint 9. When the pump is working, water is transported to the water supply pipe 3, and then high-pressure water jets are sprayed from the main high-pressure nozzle 4 and auxiliary high-pressure nozzles 5 to flush and remove the sludge inside the water conservancy pipeline. An electric push rod 7 is fixed on the support ring seat 1. The top of the electric push rod 7 is connected to a movable wheel 8. When facing pipes of different diameters, the electric push rod 7 is activated to adjust the extension or retraction position of the movable wheel 8. When the movable wheel 8 contacts the inner wall of the pipe and can move, the electric push rod 7 is turned off. Then, the movable wheel 8 moves on the inner wall of the pipe, and at the same time, the nozzle sprays high-pressure water to remove sludge.

[0030] The number of auxiliary high-pressure nozzles 5 is set to several. The auxiliary high-pressure nozzles 5 are evenly distributed on the outer surface of the front end of the water conveying pipe 3 in a circular array. When the water conveying pipe 3 conveys water, the auxiliary high-pressure nozzles 5 in all directions can spray high-pressure water flow, so that the sludge around the inner wall of the pipe can be flushed more evenly and comprehensively during the sludge removal.

[0031] There are three movable wheels 8. The three movable wheels 8 are evenly distributed on the outer surface of the support ring seat 1 in a circular array. Under the push of the electric push rod 7, the three movable wheels 8 can move closer to or away from the inner wall of the pipe at the same time. After contacting the inner wall of the pipe, it can ensure that the support ring seat 1 moves stably in the pipe and can adapt to pipes of different diameters.

[0032] The surface of the water supply pipeline 3 is fixedly connected with a pipe joint 9. The external pump equipment delivers water into the water supply pipeline 3 through the pipe joint 9, thereby providing a water source for the main high-pressure nozzle 4 and the auxiliary high-pressure nozzle 5 to achieve high-pressure water jet removal.

[0033] A push rod 10 is fixedly connected to the surface of the water pipeline 3. During the sludge removal process, the push rod 10 pushes the water pipeline 3 to move into the pipeline, thereby driving the main high-pressure nozzle 4 and the auxiliary high-pressure nozzle 5 to move in the pipeline and remove sludge from different positions of the pipeline.

[0034] A hydraulic rod 11 is fixedly connected to the surface of the push rod 10. The surface of the hydraulic rod 11 is provided with an outer sleeve 12. When the hydraulic rod 11 extends, it will push the push rod 10 because it is connected to the push rod 10, thereby driving the water pipeline 3 to move into the pipeline and realize the sludge removal work.

[0035] The hydraulic rod 11 is fixedly connected to the inner wall of the outer sleeve 12.

[0036] The implementation principle of a water conservancy pipeline sludge removal device in this application embodiment is as follows: Based on the required pipeline diameter for sludge removal, the electric push rod 7 is activated. The electric push rod 7 pushes the movable wheel 8 at the top to extend or retract. The movement of the movable wheel 8 is observed. When the movable wheel 8 contacts the inner wall of the pipeline and can move smoothly within the pipeline, the electric push rod 7 is turned off. At this time, the three movable wheels 8 are evenly distributed in a circular array on the outer surface of the support ring seat 1, ensuring that the support ring seat 1 moves stably within the pipeline and adapts to the pipeline diameter. The external pump body is then activated, and the pump body delivers water to the water supply pipeline 3 through the pipeline joint 9. The water flows within the water supply pipeline 3, and high-pressure water jets are sprayed from the main high-pressure nozzle 4 and the auxiliary high-pressure nozzle 5. Several auxiliary high-pressure nozzles... 5. The front end of the water supply pipe 3 is evenly distributed in a circular array on the outer surface to uniformly and thoroughly flush and remove the silt around the inner wall of the pipe. The hydraulic rod 11 is activated and extends. Since the hydraulic rod 11 is connected to the push support rod 10 and fixed to the inner wall of the outer sleeve 12, the extension of the hydraulic rod 11 will push the push support rod 10. The push support rod 10 pushes the water supply pipe 3 to move into the pipe, driving the main high-pressure nozzle 4 and the auxiliary high-pressure nozzle 5 to move in the pipe to remove silt from different positions of the pipe. After the silt removal work is completed, the pump equipment is turned off to stop the water supply to the water supply pipe 3. The nozzles stop spraying high-pressure water. The hydraulic rod 11 is turned off to stop the push support rod 10 from pushing the water supply pipe 3. Then the personnel take out the device.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
