Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering dredging technology, specifically a dredging device for water conservancy projects. Background Technology

[0002] In the survival and development of human society, it is necessary to constantly adapt to, utilize, transform, and protect the water environment. Water conservancy projects develop continuously along with the growth of social productivity. Water conservancy projects often require the removal of silt to reduce silt accumulation, thus necessitating the use of silt removal mechanisms.

[0003] Meanwhile, the announcement number CN222206548U, "A Dredging Machine for Water Conservancy Projects," describes a dredging machine for water conservancy projects. This machine includes a support plate, a storage tank connected to the top of the support plate, a motor base connected to the top of the support plate, a motor mounted on the top of the motor base, an electric push rod connected to one end of the motor, a push plate connected to one end of the electric push rod, and a bracket connected to the top of the storage tank. This invention utilizes a suction pump to draw sludge into a first pipe via a suction pipe, from which it is discharged into the storage tank. Simultaneously, the motor is activated, causing the electric push rod to generate thrust. The moving electric push rod causes the push plate to compress the sludge inside the storage tank. The water contained in the compressed sludge flows out of the storage tank through an outlet and into a water tank via a water outlet pipe. This avoids wasting storage space due to water in the sludge and prevents a reduction in the effectiveness and efficiency of sludge removal.

[0004] The above-mentioned technical solution has the disadvantage of not being easily disassembled and assembled due to the integrated structure of the suction pipe. During the dredging process, the silt has a complex composition, containing a large amount of mud, sand, stones, aquatic plants and various debris. As the dredging work continues, these substances will inevitably accumulate inside the suction pipe. When the accumulation reaches a certain level, it will easily cause pipe blockage and seriously hinder the normal progress of the dredging work.

[0005] Therefore, a dredging device for water conservancy projects is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a dredging device for water conservancy projects. It has the advantage of being able to disassemble and assemble the suction pipe, thus avoiding the blockage caused by impurities such as sand, stones, aquatic plants and various debris inside the silt, which would seriously hinder the normal progress of dredging work after long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dredging device for water conservancy projects, including a traveling vehicle, a sludge tank installed on the surface of the traveling vehicle, a sludge pumping mechanism installed on the surface of the sludge tank, a sludge pumping pipe provided on one side surface of the sludge tank, and a disassembly and assembly assembly installed on the surface of the sludge tank.

[0008] The disassembly and assembly assembly includes a connecting pipe. One end of the sludge suction pipe is connected to the connecting pipe.

The connecting pipe is connected to the sludge suction pump mechanism. A positioning plate is installed on the surface of the connecting pipe. The positioning plate is inserted into the interior of the disassembly and assembly pipe. A support plate is installed on the surface of the positioning plate. A connecting rod is slidably connected inside the support plate. One end of the connecting rod passes through the support plate and extends to the top of the support plate, and is connected to a positioning block provided on the top of the support plate. A blocking block is symmetrically installed on the surface of the disassembly and assembly pipe. An auxiliary operation assembly is installed on the surface of the support plate.

[0009] Preferably, the positioning block abuts against one side surface of the blocking block.

[0010] Preferably, a pin is installed on one side surface of the blocking block, and the pin is inserted into a socket opened on the surface of the positioning block.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6 As shown, this utility model provides a dredging device for water conservancy projects, including a traveling vehicle 1, a sludge tank 12 installed on the surface of the traveling vehicle 1, a sludge pumping mechanism 13 installed on the surface of the sludge tank 12, a sludge pumping pipe 14 provided on one side surface of the sludge tank 12, and a disassembly and assembly assembly 2 installed on the surface of the sludge tank 12.

[0027] The disassembly assembly 2 includes a connecting pipe 21. One end of the sludge suction pipe 14 is connected to the connecting pipe 21. A disassembly assembly pipe 22 is provided on one side surface of the sludge tank 12. The disassembly assembly pipe 22 is connected to the sludge suction pump mechanism 13 via a flange. A positioning plate 23 is installed on the surface of the connecting pipe 21 and is inserted into the interior of the disassembly assembly pipe 22. A support plate 24 is installed on the surface of the positioning plate 23. A connecting rod 25 is slidably connected inside the support plate 24, and one end of the connecting rod 25 passes through the support plate 24. Plate 24 extends above support plate 24 and connects with positioning block 26 located above support plate 24. Blocking blocks 27 are symmetrically installed on the surface of disassembly pipe 22, and auxiliary operation components 3 are installed on the surface of support plate 24. This enables convenient disassembly and assembly of mud suction pipe 14, avoiding the situation where mud suction pipe 14 cannot be disassembled and long-term use leads to sludge accumulation in the pipe, causing blockage that is difficult to clean. This effectively avoids long-term accumulation of sludge in the pipe, greatly reduces the risk of pipe blockage, and extends the service life of the equipment.

[0028] Specifically, the positioning block 26 abuts against one side surface of the blocking block 27, thereby enabling the positioning block 26 to be positioned.

[0029] like Figures 1 to 6 As shown, a pin 28 is installed on one side surface of the blocking block 27. The pin 28 is inserted into the socket opened on the surface of the positioning block 26, thereby enabling further positioning of the positioning block 26.

[0030] Furthermore, a strip plate 29 is snapped into the groove of the disassembly tube 22. Multiple rubber pads 210 are evenly distributed on the side of the strip plate 29 near the center of the disassembly tube 22. The rubber pads 210 are in contact with the connecting tube 21, which can stabilize the connecting tube 21 and increase the friction between them.

[0031] It is worth noting that the surface of the disassembly tube 22 is threaded with a fastening ring 211, which allows the disassembly tube 22 to be fastened and tightly fitted to the surface of the connecting tube 21.

[0032] like Figures 1 to 6 As shown, the auxiliary operation component 3 includes a limiting plate 31. The limiting plate 31 is installed at the other end of the connecting rod 25. An auxiliary handle 32 is installed on the surface of the limiting plate 31. A relief groove 33 adapted to the auxiliary handle 32 is opened on the surface of the support plate 24. The auxiliary handle 32 is slidably connected inside the relief groove 33 and extends to the outside of the relief groove 33. A force-applying strip 34 is installed on the surface of the auxiliary handle 32. The auxiliary handle 32 and the force-applying strip 34 provide the operator with a convenient way of operation. By holding the auxiliary handle 32, the connecting rod 25 and the positioning block 26 can be easily moved to realize the connection and disassembly of the connecting pipe 21 and the disassembly pipe 22. The force-applying strip 34 increases the friction between the operator's hand and the auxiliary handle 32, making the operation more labor-saving and effectively reducing the operator's fatigue even during long-term operation.

[0033] It is worth emphasizing that a return spring 35 is sleeved on the surface of the connecting rod 25. One end of the return spring 35 is connected to the limiting plate 31, and the other end of the return spring 35 is installed inside the support plate 24, which makes it easy to reset the position of the positioning block 26, so that it can spring up and lock after being released.

[0034] The structures such as the driving vehicle 1, sludge tank 12, sludge pump mechanism 13, and sludge pipe 14 are existing technologies and have the same working principle as the comparative patent, announcement number CN222206548U, "A Dredging Machine for Water Conservancy Projects". For specific operation, please refer to the comparative patent.

[0035] Working principle and process: Drive the vehicle 1 to the dredging site. At this time, the operator starts the mud pump mechanism 13. The mud pump mechanism 13 extracts the silt from the water conservancy project through the connecting pipe 21 and the mud pumping pipe 14. The extracted silt enters the silt box 12, thereby realizing subsequent operations. For details, please refer to the comparative patent.

[0036] When the mud suction pipe 14 becomes clogged and needs to be cleaned after prolonged use, after the mud suction pump mechanism 13 stops running, first rotate the fastening ring 211 to unscrew it from the surface of the disassembly pipe 22. Then press the auxiliary handle 32. Since the auxiliary handle 32 is installed on the limiting plate 31, which is connected to the connecting rod 25, press the auxiliary handle 32 down. At this time, the auxiliary handle 32 slides in the clearance groove 33 opened on the surface of the support plate 24, causing the connecting rod 25 to move downward against the elastic force of the return spring 35, thereby causing the positioning block 26 to move downward and disengage from the abutment state with the blocking block 27. At this time, the positioning block 26 separates from the pin 28. Then pull the connecting pipe 21 to overcome the resistance of the rubber pad 210 on the strip plate 29, so that the positioning plate 23 on the connecting pipe 21 drives the support plate 24 to slide inside the disassembly pipe 22, thereby realizing the disassembly of the connecting pipe 21 and the mud suction pipe 14.

[0037] During installation, first align the positioning plate 23 with the disassembly tube 22, then press down on the auxiliary handle 32. The force strip 34 on the auxiliary handle 32 can better apply force. At this time, the auxiliary handle 32 slides in the clearance groove 33 on the surface of the support plate 24, driving the connecting rod 25 to move downward against the elastic force of the return spring 35. Then push the positioning plate 23, so that the positioning plate 23 drives the support plate 24 to slide inside the disassembly tube 22. At this time, the positioning block 26 slides at the bottom of the blocking block 27. Move the positioning block 26 to a position that aligns with one side surface of the blocking block 27 that is symmetrically installed on the surface of the disassembly tube 22. Release the auxiliary handle 32. At this time, under the action of the return spring 35, the positioning block 26 moves upward quickly and tightly abuts against one side surface of the blocking block 27. At this time, the pin 28 is inserted into the insertion hole on the surface of the positioning block 26, thereby realizing the positioning of the positioning block 26.

[0038] Multiple rubber pads 210 are evenly distributed on the side of the strip plate 29 near the center of the disassembly tube 22 to ensure that the rubber pads 210 are in close contact with the connecting tube 21. These rubber pads 210 increase the friction between the connecting tube 21 and the connecting tube 21, thereby stabilizing the position of the connecting tube 21 and reducing the vibration of the connecting tube 21. Finally, by rotating the fastening ring 211, the fastening ring 211 is threaded onto the surface of the disassembly tube 22. At this time, the disassembly tube 22 receives the fastening force and is tightly attached to the connecting tube 21, thereby stabilizing the position of the connecting tube 21.

[0039] When it is necessary to separate the disassembly pipe 22 from the mud pump mechanism 13, the disassembly and installation operations can be achieved through the operating flange.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
