Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipe cleaning, and in particular relates to a pipeline silting device. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment, so that water resources can be rationally allocated and utilized. These include flood control, water diversion and other engineering projects. A variety of pipelines are needed in the water diversion process. Long-term water diversion will cause silt and other debris to accumulate inside the pipeline, requiring staff to regularly desilt to avoid blockage.

[0003] In view of the above problems, devices for cleaning pipeline sludge have appeared in the prior art, for example, a drainage pipe silt cleaning mechanism with patent authorization announcement number CN 220469096 U is provided with a silt cleaning head seat, and a first nozzle and a second nozzle are provided at the rear of the silt cleaning head seat for moving and flushing sludge; although the device can realize the cleaning of sludge, there are still certain problems. When the silt cleaning head seat is located inside the pipeline, there is no corresponding supporting device and it can only be placed at the bottom of the pipeline. During the silt cleaning process, the water sprayed by the second nozzle can clean the inner wall of the pipeline. For the silt on the top of the pipeline, the impact force of the water may be insufficient, resulting in its incomplete cleaning. If the water pressure is increased so that its impact force can clean the sludge above the inner wall of the pipeline, a large amount of water resources will be wasted. Utility Model Content

However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0033] like Figure 1-3 As shown, this embodiment provides a pipeline desilting device, which includes:

[0034] A spiral cone head 1, the tail of the spiral cone head 1 is connected with a plurality of groups of high-pressure nozzles 2 for driving the spiral cone head 1 to rotate and feed; specifically, the tail end of the spiral cone head 1 has a cavity 3, the high-pressure nozzles 2 are arranged circumferentially with the outer wall of the cavity 3 and are connected with the cavity 3, the plurality of groups of high-pressure nozzles 2 are arranged in a circular and inclined manner, the high-pressure nozzles 2 are inclined as a whole, and the inclination direction is consistent with clockwise or counterclockwise;

[0035] An intermediate water pipe 4, which is connected to the spiral cone head 1. Specifically, the intermediate water pipe 4 is connected to the cavity 3 in the spiral cone head 1. A plurality of groups of support plates 5 are arranged in an annular direction outside the intermediate water pipe 4, and the support plates 5 can be synchronously unfolded for support;

[0036] The water pipe 6 is connected to the middle water pipe 4. In the present embodiment, the water pipe 6 is a flexible pipe.

[0037] In actual use, water is input into the volume 3 of the spiral cone head 1 through the water pipe 6, and then the high-pressure nozzle 2 is ejected. Since the high-pressure nozzle 2 is tilted, the water impacts the sludge or the inner wall of the pipe during the ejection process, and the reaction force brought by the water drives the spiral cone head 1 to rotate and feed. In order to make the water ejected by the high-pressure nozzle 2 more evenly impact the sludge passing through the inner wall of the pipe, a plurality of groups of synchronously deployable support plates 5 are provided on the high-pressure nozzle 2. When the support plates 5 are deployed, the spiral cone head 1 can be located at the center of the pipe. Compared with the spiral head being directly placed at the bottom of the pipe, the sludge in the inner wall of the pipe is more evenly impacted, and the sludge cleaning efficiency is more outstanding.

[0038] In order to realize the synchronous expansion of the support plates 5, the following structure is adopted in this embodiment: a fixed limiting ring 7 and a linearly movable propulsion ring 8 are arranged on the outer wall of the middle water pipe 4, and the limiting ring 7 and the propulsion ring 8 are jointly provided with the above-mentioned several groups of support plates 5, and when the propulsion ring 8 moves close to the limiting ring 7, several groups of support plates 5 are lifted up to realize their expansion. Specifically, the method of lifting the support plates 5 by moving the propulsion ring 8 is that several groups of first hinged plate assemblies 9 are hinged on the limiting ring 7, and several groups of second hinged plate assemblies 10 are hinged on the propulsion ring 8, and the first hinged plate assemblies 9 and the second hinged plate assemblies 10 are hinged and the tops are jointly connected with the support plates 5.

[0039] Furthermore, the stop ring 7 and the propulsion ring 8 are both provided with a plurality of sets of ear plate sets 11, and the ear plate sets 11 on the stop ring 7 and the propulsion ring 8 are both hinged to the first hinge plate assembly 9 and the second hinge plate assembly 10. The rear section of the intermediate water pipe 4 is provided with a threaded section 12, and the threaded section 12 is threadedly connected with a propulsion nut 13, and the propulsion nut 13 is located behind the propulsion ring 8.

[0040] During actual use, by screwing the push nut 13, the push ring 8 is pushed toward the limit ring 7 during the feeding process. During the approaching process, the support plate 5 connected to the first hinge plate assembly 9 and the second hinge plate assembly 10 is driven to expand outward. When the support plate 5 is expanded to fit the inner wall of the pipe, it is ready.

[0041] Furthermore, a cleaning brush 14 is detachably connected to the support plate 5. When the spiral cone head 1 rotates, the intermediate water pipe 4 and the support plate 5 connected to the intermediate water pipe 4 are driven to rotate synchronously. The cleaning brush 14 arranged on the support plate 5 can further clean the silt on the inner wall of the pipe during the rotation process, thereby improving the cleaning efficiency.

[0042] Working principle of this device:

[0043] Connect the water pipe 6 to the external high-pressure pump in advance;

[0044] Put the spiral cone head 1 into the pipe to be cleaned, and screw the push nut 13. During the rotation of the push nut 13, the push ring 8 is pushed to move toward the limit ring 7, so that the plurality of support plates 5 are expanded outward until the cleaning brush 14 is attached to the inner wall of the pipe;

[0045] The water is transported to the cavity 3 of the spiral cone head 1 by a high-pressure pump, and the pressurized water is sprayed toward the inner wall of the water pipe or the sludge on the inner wall through the high-pressure nozzle 2. The reaction force brought by the water propels the spiral cone head 1 to rotate and feed at the same time. During the rotation of the spiral cone head 1, the sludge is further flushed by the water sprayed by the high-pressure nozzle 2 to achieve the purpose of cleaning. Subsequently, the cleaning brush 14 rotates to clean the inner wall of the pipe, thereby achieving a deeper cleaning of the sludge inside the pipe.

[0046] As an optional embodiment, a rotating joint may be connected between the spiral nozzle head and the intermediate water pipe 4. The rotating joint may also be connected between the intermediate water pipe 4 and the water pipe 6, or be set in other places to avoid affecting the connection between the water pipe 6 and the high-pressure pump when the spiral cone head 1 rotates.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
