Water is an indispensable precious resource for human production and life. However, its natural state does not fully meet the needs of humans. Only by building a water conservancy project can the water flow be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. During the construction of a water conservancy project, the silt at the bottom needs to be cleared to build buildings.

Small-sized stones can flow normally inside the pipeline along with the silt, but large-sized stones will damage the pump body or block the dredging device. Although the existing dredging pipes are equipped with a filter screen at the head for protection, the installation method is inconvenient. Content of the Utility Model

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0029] In the related art, the silt in the river channel often contains a large amount of stones. Small-volume stones can flow normally inside the pipeline along with the silt, but large-volume stones will damage the pump body or block the dredging device. Although the existing dredging pipes are equipped with filter nets at the head for protection, the installation method is inconvenient.

[0030] To solve the problems in the related art to a certain extent, the embodiments of the present application provide a water conservancy project dredging device. When in use, only need to sleeved the cylinder body 21 on the pipeline 13 and the suction head 14, and connect them with bolts. And the suction head 14 is located between the top wall of the cylinder body 21 and the first plate 23, which increases the stability between the cylinder body 21 and the suction head 14.

[0031] Next, the present application will be described in conjunction with the accompanying drawings and with reference to specific embodiments:

[0032] Combined with Figures 1 - 4 , an embodiment of the present application provides a dredging device for water conservancy projects, including a dredging component 1; the dredging component 1 includes: a pump body 12 is arranged on the top of a base 11; a pipeline 13 is arranged at the suction port of the pump body 12; a suction head 14 is arranged at one end of the pipeline 13; an auxiliary component 2 is arranged on the pipeline 13, and the auxiliary component 2 includes: a cylinder body 21 is sleeved on the outer side walls of the pipeline 13 and the suction head 14; a through hole 22 is opened on the outer side wall of the cylinder body 21; a fixing block 24 is arranged on the outer side wall of the cylinder body 21; a fixing bolt 25 connects the fixing block 24.

[0033] When in use, first connect the pipeline 13 to the pump body 12 of the base 11, then sleeve the cylinder body 21 on the pipeline 13 and the suction head 14 of the pipeline 13, align the fixing blocks 24, and use the fixing bolt 25 to connect the fixing blocks 24 to fix the cylinder body 21. Then large-volume stones are filtered out by the cylinder body 21, and the silt is sucked in through the through holes 22 and discharged through the pipeline 13.

[0034] In some embodiments, a plate body 23 is arranged inside the cylinder body 21, and through holes 22 are opened in the plate body 23. The plate body 23 cooperates with the top of the cylinder body 21 to sleeve the suction head of the pipeline 13 in the middle, which can effectively reduce the blockage caused by the suction head contacting large-volume stones.

[0035] In some embodiments, insertion pins 231 and grooves matching the insertion pins 231 are arranged on the inner wall of the plate body 23. Only the mutually matching insertion pins 231 and grooves exist between the plate bodies 23 to assist in fixing between the plate body 23 and the cylinder body 21 and increase stability.

[0036] In some embodiments, a plate body 26 is arranged inside the cylinder body 21, and the plate body 26 is connected to the through hole 22 by bolts. The plate body 26 cooperates with the plate body 23 to further increase the protection of the suction head 14. Since the suction force of the suction head is directly downward, the number of the plate bodies 26 installed can be freely selected and the distance between the plate body 26 and the plate body 23 can be adjusted, and they are fixed by bolts through the through holes 22.

[0037] In some embodiments, a plurality of rod bodies 27 are arranged at the bottom of the cylinder body 21. The rod bodies 27 are used to increase the height of the cylinder body 21, prevent the cylinder body 21 from completely entering the silt, and increase the working power of the pump body.

[0038] In some embodiments, a fixing part 28 is arranged at the top of the rod body 27, and a fixing bolt 281 is arranged between the fixing part 28 and the through hole 22. The fixing part 28 passes through the through hole 22 by the fixing bolt 281 to assist in the installation of the rod body 27, which is convenient for the disassembly and replacement of the rod body 27.

[0039] In some embodiments, the cylinder body 21 has a cylindrical structure. The cylinder body 21 is arranged in a cylindrical shape, which can reduce the damage caused by collision with the stones at the bottom of the river.

[0040] In some embodiments, the diameter of the rod body 27 is greater than the wall thickness of the cylinder body 21. This enables the rod body 27 to have a certain strength, making it not easily bend and being able to support the cylinder body 21 well.

[0041] In the description of this specification, the descriptions with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
