Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a suspended sludge discharge pipe for dredging projects. Background Technology

[0002] Dredging engineering mainly refers to the process of excavating and transporting underwater soil and rock using hydraulic or mechanical methods. It is primarily used for dredging, widening, and deepening rivers and lakes, and is of great significance for port and urban construction, as well as economic and social development. Dredgers and discharge pipes are commonly used equipment in dredging operations. Discharge pipes are mainly divided into ordinary steel discharge pipes and composite discharge pipes.

[0003] Currently, most onshore steel reclamation pipelines are directly connected by flanges and bolts. This connection method has significant drawbacks. Since it is impossible to guarantee the alignment of the flange holes on the two flanges, workers need to adjust the rotation angle of the other pipeline. However, since the diameter of the sludge discharge pipe is usually large, it is difficult to manually drive its rotation, which reduces the efficiency of the pipeline connection process. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a suspended sludge discharge pipe for dredging projects.

[0005] The technical solution of this utility model is a suspended sludge discharge pipe for dredging projects, comprising:

[0006] The suspended sludge discharge pipe has port rings connected to both ends; a sealing ring is installed on one side of the port ring.

[0007] The fixed installation mechanism includes a fixed ring, a movable ring, and multiple sets of bolt fixing components. The fixed ring and the movable ring are respectively located at both ends of the suspended sludge discharge pipe. The fixed ring is fixedly connected to the suspended sludge discharge pipe, and the movable ring is movably located on the outer periphery of the suspended sludge discharge pipe. Multiple first through holes and multiple second through holes are respectively opened on the fixed ring and the movable ring. The fixed ring and the movable ring are detachably connected by multiple sets of bolt fixing components.

[0008] Preferably, the bolt fastening assembly includes a bolt and a nut.

[0009] Preferably, it also includes multiple reinforcing frames, which are symmetrically arranged at both ends. The middle part of the reinforcing frame is "U"-shaped, and both ends of the reinforcing frame extend along the length of the suspended sludge discharge pipe. Both ends of the reinforcing frame fit into the surface of the suspended sludge discharge pipe. A third through hole for bolts to pass through is opened at both ends of the middle part of the reinforcing frame.

[0010] Preferably, a nut limiting groove is provided at one end of the middle of the reinforcing frame, and a wedge block is slidably connected to the other end of the middle of the reinforcing frame, with an elastic rope connecting the wedge block and the reinforcing frame.

[0011] Preferably, a ring is connected to the port ring on the side away from the sealing ring, and an annular sealing groove is formed on the sealing ring.

[0012] Preferably, the multiple first perforations are configured to correspond one-to-one with the multiple second perforations.

[0013] Preferably, the inner diameter of the sealing ring is equal to the inner diameter of the suspended sludge discharge pipe.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: By setting a rotatable movable ring in the present technical solution, compared with the traditional flange connection structure, the tedious hole-aligning operation before installation is eliminated, thus enabling the rapid connection of two suspended mud discharge pipes, thereby improving installation efficiency.

[0019] Example 1

[0020] like Figures 1-4 As shown in the figure, this embodiment proposes a suspended sludge discharge pipe for dredging projects, including a suspended sludge discharge pipe 1 and a fixed installation mechanism.

[0021] Both ends of the suspended sludge discharge pipe 1 are connected to port rings 8; a sealing ring 5 is installed on one side of the port ring 8, and the inner diameter of the sealing ring 5 is equal to the inner diameter of the suspended sludge discharge pipe 1. This setting can prevent local turbulence and increased flow resistance inside the pipe; a ring 6 is connected to the port ring 8 on the side away from the sealing ring 5, and an annular sealing groove 501 is opened on the sealing ring 5. During installation, the ring 6 is inserted into the inner side of the annular sealing groove 501. The above structure can increase the sealing area and thus improve the sealing effect.

[0022] The fixed installation mechanism includes a fixed ring 2, a movable ring 3, and multiple sets of bolt fixing components. The fixed ring 2 and the movable ring 3 are respectively located at both ends of the suspended sludge discharge pipe 1. The fixed ring 2 is fixedly connected to the suspended sludge discharge pipe 1, and the movable ring 3 is movably located on the outer periphery of the suspended sludge discharge pipe 1. The fixed ring 2 and the movable ring 3 are respectively provided with multiple first through holes 201 and multiple second through holes 301. The multiple first through holes 201 and multiple second through holes 301 are arranged one-to-one. The fixed ring 2 and the movable ring 3 are detachably connected by multiple sets of bolt fixing components. The bolt fixing components include bolts 71 and nuts 72.

[0023] In this embodiment, when connecting the two suspended sludge discharge pipes 1, the two suspended sludge discharge pipes 1 are aligned so that they are coaxially arranged. Then, the movable ring 3 is rotated until the multiple second through holes 301 correspond one-to-one with the multiple first through holes 201. Multiple sets of bolt fixing components are used to fix the fixed ring 2 and the movable ring 3. After the bolt 71 passes through the first through hole 201 and the second through hole 301, it is threaded through the nut 72. The bolt 71 is tightened with a tool. Through the above connection structure, the two suspended sludge discharge pipes 1 can be quickly connected, eliminating the tedious intermediate hole alignment work and thus improving the installation efficiency.

[0024] Example 2

[0025] like Figures 2-4 As shown, this embodiment proposes a suspended sludge discharge pipe for dredging projects. Compared with Embodiment 1, this embodiment also includes multiple reinforcing frames 4. The reinforcing frames 4 are symmetrically arranged at both ends, and the middle part of the reinforcing frame 4 is "U" shaped. The reinforcing frame 4 is made of high-strength alloy material, and both ends of the reinforcing frame 4 extend along the length direction of the suspended sludge discharge pipe 1, and both ends of the reinforcing frame 4 fit with the surface of the suspended sludge discharge pipe 1. The middle part of the reinforcing frame 4 has a third through hole 401 for bolts 71 to pass through. Before connecting and fixing the ring 2 and the movable ring 3, the reinforcing frame 4 is first installed so that the third through hole 401 is aligned with the first through hole 201 and the second through hole 301. The bolts 71 are passed through the first through hole 201, the second through hole 301 and the third through hole 401 and then fixed with nuts 72. The installed reinforcing frame 4 can strengthen the connection strength between two adjacent suspended sludge discharge pipes 1. The reinforcing frame 4 wraps around the local part of the pipe connection, which can disperse stress and reduce local stress concentration.

[0026] The reinforcing frame 4 has a nut limiting groove 402 at one end of its middle section. The nut 72 is placed inside the nut limiting groove 402, which can limit the nut 72. At this time, the bolt 71 can be rotated by simply driving the tool. The other end of the reinforcing frame 4 is slidably connected to a wedge block 9. An elastic rope 10 is connected between the wedge block 9 and the reinforcing frame 4. Before rotating the bolt 71, the wedge block 9 should be pulled to the side away from the bolt 71. When the bolt 71 is tightened to the limited position, the wedge block 9 is released. At this time, under the elastic force of the elastic rope 10, the tip of the wedge block 9 is driven to get into the gap between the head of the bolt 71 and the reinforcing frame 4. Through the cooperation with the nut limiting groove 402, the bolt 71 and the nut 72 can be prevented from loosening.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
