Description

Technical Field

[0001] The present application relates to the field of silt removal, and in particular to a silt removal pipeline for silt removal. Background Art

[0002] Ditches, canals and other sewage structures often need to be desilted after long-term use to reduce the occurrence of blockage of the sewage structures.

[0003] Dredging is typically accomplished using dredging equipment, dredging pipes, connecting pipes, and dredging hoses. The dredging equipment generates negative pressure and stores waste, while the dredging pipes connect the dredging equipment to the connecting pipes. The connecting pipes connect to the dredging hoses, which extend into the drainage structure to draw waste.

[0004] In the existing related technology, the dredging hard pipe and the connecting hard pipe are connected through a clamp joint, that is, the dredging hard pipe and the connecting hard pipe are fixedly plugged into the two ends of the clamp joint respectively, so that the dredging hard pipe and the connecting hard pipe are connected through the connecting chamber inside the clamp joint.

[0005] Regarding the above-mentioned related technologies, during actual use, leakage is likely to occur between the dredging hard pipe and the connecting hard pipe, affecting the dredging work. Summary of the Invention

[0006] In order to prevent leakage from occurring between the silt removal hard pipe and the connecting hard pipe, the present application provides a silt removal pipeline for silt removal.

[0007] The present application provides a silt removal pipeline that adopts the following technical solution:

[0008] A silt removal pipe for silting, comprising a silt removal hard pipe and a connecting hard pipe;

[0009] The connecting rigid pipe includes a connecting abutment portion and a connecting plug portion. The connecting abutment portion is flange-connected to the dredging rigid pipe. The connecting abutment portion is arranged in a truncated cone shape. The connecting plug portion is connected to the end of the connecting abutment portion with a smaller outer diameter. The connecting plug portion is used to sleeve the dredging hose and plug it into the connecting rigid pipe.

[0010] By adopting the above technical solution, the flange-connected dredging pipe and the connecting pipe are more stable, making it less likely for leakage to occur between the dredging pipe and the connecting pipe. In addition, by inserting the connecting plug into the dredging hose and sealing the end of the dredging hose with the frustum-shaped connecting abutment, leakage at the end of the dredging hose is also reduced.

[0011] Optionally, the connecting abutment portion is provided with a connecting column, and the dredging hose plugged into the connecting plug portion is connected to the connecting column via a connecting rope.

[0012] By adopting the above technical solution, the dredging hose is plugged into the connecting plug part and then connected to the connecting column through the connecting rope, which is conducive to ensuring the connection stability between the dredging hose and the connecting hard pipe, thereby further reducing the occurrence of leakage.

[0013] Optionally, the connecting plug portion is chamfered away from the pipe opening of the connecting abutment portion.

[0014] By adopting the above technical solution, it is convenient for operators to align the connecting plug part and insert it into the dredging hose.

[0015] Optionally, the desilting hard pipe and the connecting hard pipe are both made of metal.

[0016] The adoption of the above technical solution is helpful to ensure the service life of the dredging hose and the connecting hard pipe.

[0017] Optionally, the connecting plug portion is provided with a sealing ring.

[0018] By adopting the above technical solution, after the dredging hose is plugged into the connecting plug part, the sealing ring is tightly fitted into the inner wall of the dredging hose, which is conducive to reducing the occurrence of leakage.

[0019] Optionally, a sealing groove is provided on the outer peripheral surface of the connecting plug portion, and the sealing ring is embedded in the sealing groove.

[0020] By adopting the above technical solution, it is beneficial to fix the sealing ring and it is convenient to replace the sealing ring when the sealing ring is not suitable.

[0021] Optionally, the connecting column includes a telescopic column and a fixed end head, the fixed end head is telescopically arranged on the telescopic column, and the outer diameter of the fixed end head is larger than the outer diameter of the telescopic column.

[0022] By adopting the above technical solution, the fixed end limits the connection rope wrapped around the telescopic column, so that the connection rope is not easy to fall off from the telescopic column.

[0023] Optionally, the connecting column is provided with a threaded cavity, and the fixed end is threadedly fitted into the threaded cavity.

[0024] By adopting the above technical solution, after the connecting rope is wrapped around the connecting column, the fixed end is rotated so that the fixed end is tightly fitted against the connecting rope, which is beneficial to improving the connection stability between the connecting rope and the connecting column.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The flange-connected dredging pipe and the connecting pipe are more stable, making it less likely for leakage to occur between the dredging pipe and the connecting pipe. In addition, by inserting the connecting plug into the dredging hose and sealing the end of the dredging hose with the frustum-shaped connecting abutment, leakage at the end of the dredging hose is also reduced.

[0027] 2. After the dredging hose is plugged into the connecting plug part, it is then connected to the connecting column through the connecting rope, which helps to ensure the connection stability between the dredging hose and the connecting hard pipe, thereby further reducing the occurrence of leakage;

[0028] 3. After the connecting rope is wrapped around the connecting column, rotate the fixed end so that the fixed end is tightly fitted against the connecting rope, which is beneficial to improving the connection stability between the connecting rope and the connecting column.

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] Example 1:

[0036] The embodiment of the present application discloses a silt removal pipeline for silting. Figure 1 The silt removal pipeline includes a silt removal hard pipe 1 and a connecting hard pipe 2. The materials of the silt removal hard pipe 1 and the connecting hard pipe 2 are both metal, such as iron or steel.

[0037] One end of the dredging rigid pipe 1 is connected to the dredging equipment (not shown in the figure). The connecting rigid pipe 2 includes a connecting abutment portion 21 and a connecting plug portion 22. The connecting abutment portion 21 of the connecting rigid pipe 2 is arranged in a truncated cone shape, and the end of the connecting abutment portion 21 with a larger outer diameter is flange-connected to the other end of the dredging rigid pipe 1, and the connecting abutment portion 21 is arranged coaxially with the dredging rigid pipe 1. The connecting plug portion 22 of the connecting rigid pipe 2 is arranged in a cylindrical shape, and the connecting plug portion 22 is integrally connected to the end of the connecting abutment portion 21 with a smaller outer diameter. The connecting plug portion 22 is used to sleeve the dredging hose and plug it into the connecting rigid pipe 2, thereby connecting the dredging hose to the dredging equipment through the connecting rigid pipe 2 and the dredging rigid pipe 1.

[0038] The outer circumference of the connecting abutment portion 21 is provided with a connecting column 3 fixedly connected by welding. The two connecting columns 3 are distributed along the axial direction of the connecting abutment portion 21. After the dredging hose is plugged into the connecting plug portion 22 of the connecting rigid pipe 2, the dredging hose can be further fixed by the connecting rope, thereby firmly connecting the dredging hose to the connecting rigid pipe 2 and ensuring that the pipe mouth of the dredging hose is tightly fitted with the truncated cone-shaped connecting abutment portion 21 of the connecting rigid pipe 2, thereby ensuring connection stability and sealing. In the present application, the connecting rope can be a flexible rope-like object such as a braided rope, iron wire, or cloth.

[0039] In addition, the outer edge of the pipe mouth of the connecting plug part 22 away from the connecting abutment part 21 is chamfered to facilitate the insertion of the connecting abutment part 21 of the required length into the interior of the dredging hose, thereby ensuring the connection stability between the dredging hose and the connecting abutment part 21, and increasing the length of the leakage path between the connecting plug part 22 and the dredging hose, so that dirt is not easily leaked.

[0040] The implementation principle of the silt removal pipe for silt removal in Example 1 of the present application is as follows: the flange-connected silt removal hard pipe 1 and the connecting hard pipe 2 are relatively stable, making it difficult for leakage to occur between the silt removal hard pipe 1 and the connecting hard pipe 2. In addition, by inserting the connecting plug 22 into the silt removal hose and sealing the end of the silt removal hose with the truncated cone-shaped connecting abutment 21, the occurrence of leakage at the end of the silt removal hose is also reduced. Moreover, after the silt removal hose is plugged into the connecting plug 22, the silt removal hose is connected to the connecting column 3 via a connecting rope, which is conducive to ensuring the stability of the connection between the silt removal hose and the connecting hard pipe 2, thereby further helping to reduce the occurrence of leakage.

[0041] Example 2:

[0042] The present application discloses a silt removal pipeline for silting, which includes all the technical features of Example 1 and also includes the following technical features:

[0043] Reference Figure 2 and Figure 3The connecting column 3 includes a telescopic column 31 and a fixed end 32. The telescopic column 31 is welded and fixedly connected to the outer circumference of the connecting rigid tube 2. A threaded cavity is provided inside the telescopic column 31. One end of the fixed end 32 is threadedly fitted into the threaded cavity so that the fixed end 32 can be extended and retracted along the axis of the telescopic column 31. Figure 4 The outer diameter of the other end of the fixed end 32 is larger than the outer diameter of the telescopic column 31, so that the connecting rope used to fix the dredging hose is fixedly wrapped around one end of the diameter size of the fixed end 32, and then by rotating the fixed end 32, the connecting rope drives the dredging hose to further fit tightly against the connecting abutment portion 21 of the connecting hard pipe 2, and it is beneficial to fit the connecting rope stably to the connecting column 3 through the end with the larger outer diameter of the fixed end 32.

[0044] Refer to 3 and Figure 4 A sealing groove 201 is provided on the outer peripheral surface of the connecting plug part 22, and a sealing ring 221 is embedded in the sealing groove 201, so that after the dredging hose is plugged into the connecting plug part 22, the sealing ring 221 is tightly fitted against the inner wall of the dredging hose, thereby reducing the occurrence of leakage.

[0045] The implementation principle of a dredging pipe for dredging in Example 2 of the present application is: the sealing between the dredging hose and the connecting hard pipe 2 is increased by using a sealing ring 221 on the outer peripheral surface of the connecting hard pipe 2, and the connecting rope is tightened and fixed by a retractable and fixed connecting column 3, thereby improving the connection stability between the dredging hose and the connecting hard pipe 2.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
