Technical Field

[0001] This utility model relates to the field of suction pump technology, and in particular to a pipe structure for a suction pump used in dredging operations. Background Technology

[0002] In municipal drainage pipe dredging construction, sewage mixed with silt is sucked in and transported to the treatment area using suction pumps and pipeline structures. Existing pump bodies and pipeline structures often have low pumping efficiency when dealing with high-concentration sludge or viscous silt, resulting in slow overall treatment speed and affecting project progress. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new structural composition that differs from existing technologies. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, which often have low pumping efficiency when dealing with high-concentration mud or viscous sludge, and to propose a suction pump pipeline structure for dredging construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A suction pump pipeline structure for dredging construction includes a first connecting pipe and a second water pipe. One end of the second water pipe is fixedly connected to the second connecting pipe. The second connecting pipe and the first connecting pipe are fixed together by a detachable connecting component. The top and bottom of the first and second connecting pipes are provided with through grooves. The top and bottom outer walls of the first and second connecting pipes are fixedly connected with positioning blocks, and two adjacent positioning blocks are in contact with each other. A slot is provided on each of the positioning blocks, and the slot is connected to the through groove. A guide pipe is inserted into the cavity formed by the slots on two adjacent positioning blocks. The bottom end of the guide pipe passes through the through groove and is fixedly connected to a high-pressure nozzle.

[0005] As a further embodiment of this utility model, the connecting assembly includes a plurality of first protrusions, which are welded to the outer wall of the second connecting pipe. Each of the plurality of first protrusions is fitted with a connecting bolt. A plurality of second protrusions are fixedly connected to the outer side of one end of the first connecting pipe. Each of the plurality of second protrusions is provided with a threaded groove, and the connecting bolt is threadedly connected to the threaded groove at the corresponding position.

[0006] As a further embodiment of this utility model, a sealing ring is fixedly connected to the bottom end of the guide tube, and the sealing ring is in contact with the inner wall of the positioning block.

[0007] As a further improvement of this utility model, the first connecting pipe has a beveled surface on its wall, and the high-pressure nozzle is designed to be inclined.

[0008] As a further embodiment of this utility model, a first water pipe is installed at one end of the first connecting pipe via a connecting assembly.

[0009] As a further embodiment of this utility model, the connecting component includes a corrugated pipe, which is bonded to one end of the first water pipe, and the other end of the corrugated pipe is connected and fixed to the first connecting pipe.

[0010] As a further embodiment of this utility model, a high-pressure water pipe is fixedly connected to the top end of the guide pipe, and a check valve is fixedly connected to the top end of the guide pipe.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model uses a high-pressure nozzle to spray water along the inclined surface of the first connecting pipe wall, creating suction at the front end of the second water pipe. This solves the problem of not being able to use conventional water pumps in some situations during municipal drainage pipe dredging construction, expands the applicability of dredging construction equipment, and improves the effectiveness of the device.

[0012] 2.

Detailed Implementation

[0016] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0017] Reference Figures 1-3 A suction pump pipeline structure for dredging construction includes a first connecting pipe 4 and a second water pipe 8. The wall of the first connecting pipe 4 is provided with an inclined surface 12. One end of the second water pipe 8 is welded with a second connecting pipe 9. The second connecting pipe 9 and the first connecting pipe 4 are fixed together by a detachable connecting component. A sealing ring is provided between the first connecting pipe 4 and the second water pipe 8. The connecting assembly includes multiple first protrusions 10, which are welded to the outer wall of the second connecting pipe 9. Each of the multiple first protrusions 10 is fitted with a connecting bolt 16. Multiple second protrusions 11 are welded to the outer side of one end of the first connecting pipe 4. Each of the multiple second protrusions 11 is provided with a threaded groove 17, and the connecting bolt 16 is threadedly connected to the threaded groove 17 at the corresponding position. The operator rotates the connecting bolt 16 to move it out of the threaded groove 17. The operator pulls the second water pipe 8 and the first connecting pipe 4 to separate the second connecting pipe 9 from the first connecting pipe 4.

[0018] In particular, the top and bottom of the first connecting pipe 4 and the second connecting pipe 9 are provided with through grooves, and the top outer wall and bottom outer wall of the first connecting pipe 4 and the second connecting pipe 9 are welded with positioning blocks 7, and two adjacent positioning blocks 7 are in contact. Each of the multiple positioning blocks 7 has a slot 15, and the slot 15 is connected to the through slot. A guide pipe 6 is inserted into the cavity formed by the slot 15 on two adjacent positioning blocks 7. The bottom end of the guide pipe 6 passes through the through slot and is threaded to a high-pressure nozzle 13. The cleaning liquid enters the guide pipe 6 and is sprayed out under high pressure through the high-pressure nozzle 13. When the second connecting pipe 9 separates from the first connecting pipe 4, the two positioning blocks 7 separate, and the staff can directly remove the guide pipe 6. The high-pressure nozzle 13 sprays water into the first connecting pipe 4 along the inclined surface 12, causing the front end of the second water pipe 8 to form a suction force, thereby sucking up mud and water. This can solve the problem of not being able to use a water pump to pump water during some of the dredging operations of municipal drainage pipes.

[0019] It should be noted that a sealing ring 14 is bonded to the bottom end of the guide pipe 6, and the sealing ring 14 is in contact with the inner wall of the positioning block 7. The sealing ring 14 is in close contact with the through grooves on the guide pipe 6, the first connecting pipe 4, and the second connecting pipe 9 to achieve sealing at the through grooves. The high-pressure nozzle 13 is designed to be tilted. One end of the first connecting pipe 4 is connected to the first water pipe 1 through a connecting assembly. The connecting assembly includes a corrugated pipe 2, which is telescopic and can adapt to the movement of the pipe, thus avoiding damage to the connection part due to changes in the position of the pipe. The corrugated pipe 2 is threaded and sealed to one end of the first water pipe 1. The other end of the corrugated pipe 2 is sealed and fixed to the first connecting pipe 4. The top end of the guide pipe 6 is connected and fixed to a high-pressure water pipe 3. The guide pipe 6 is connected to an external high-pressure cleaning vehicle through two high-pressure water pipes 3. The top end of the guide pipe 6 is fixed with a check valve 5 by bolts to prevent liquid backflow.

[0020] Working principle: When dredging is required, first connect the two high-pressure water pipes 3 to the external high-pressure cleaning vehicle, and the working pressure reaches 15 MPa. Insert the second water pipe 8 into the area that needs to be dredged, and connect the first water pipe 1 to the external high-pressure collection equipment or high-pressure extraction pump. The cleaning fluid inside the external high-pressure cleaning vehicle enters the guide pipe 6 through the high-pressure water pipe 3 and is sprayed out under high pressure through the high-pressure nozzle 13. The high-pressure nozzle 13 sprays water into the first connecting pipe 4 along the inclined surface 12, which creates suction at the front end of the second water pipe 8 to pump out mud and water. This can solve some of the working conditions where water pumps cannot be used during the dredging of municipal drainage pipes.

[0021] When it is necessary to disassemble the second water pipe 8 and the first connecting pipe 4, the worker rotates the connecting bolt 16 to move it out of the threaded groove 17, and pulls the second water pipe 8 and the first connecting pipe 4 to separate the second connecting pipe 9 from the first connecting pipe 4. At the same time, the two positioning blocks 7 separate, and the worker can directly remove the guide pipe 6.

Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
