Description

Technical Field

[0001] This utility model relates to the field of dredging devices, and in particular to a dredging device for municipal drainage pipelines. Background Technology

[0002] Municipal drainage pipelines are a crucial component of urban infrastructure, primarily used to collect and transport wastewater such as sewage and rainwater from urban life, ensuring the smooth operation of the urban drainage system. These pipelines are typically constructed from materials such as concrete, plastics (e.g., HDPE), clay, or metals (e.g., steel pipes, cast iron pipes). The appropriate pipe material is selected based on the usage scenario and geological conditions to ensure durability and functionality. Municipal drainage pipeline systems include sewage pipelines, rainwater pipelines, and combined sewer systems (which treat both sewage and rainwater). They transport wastewater to sewage treatment plants or natural water bodies through underground pipe networks, preventing urban flooding and environmental pollution. Furthermore, the design and construction of drainage pipelines must consider factors such as topography, climate, and population density to ensure they can effectively cope with drainage needs under extreme weather conditions, safeguarding urban safety and the quality of life for residents.

[0003] In existing technologies, municipal drainage pipes accumulate a large amount of silt, debris, grease and other dirt during long-term use. This dirt gradually accumulates and blocks the pipes, causing poor drainage. Therefore, dredging devices are needed to dredge municipal drainage pipes to restore their drainage capacity.

[0004] Currently, municipal pipelines are typically cleaned using sludge removal trucks. These trucks use a suction hose connected to a sludge pump to extract sludge from the drainage pipes and transfer it to a storage tank. However, during the sludge removal process, the suction hose lacks a filter, causing larger solid debris such as stones, branches, and plastic bags contained in the sludge to be sucked into the hose. This not only clogs the hose but also damages the pump, reducing the effectiveness of the sludge removal process. Utility Model Content

[0005] The main purpose of this utility model is to provide a municipal drainage pipeline dredging device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A municipal drainage pipe dredging device includes a dredging vehicle equipped with a sludge storage tank. A sludge suction pump is fixedly connected to the top surface of the sludge storage tank. A connecting pipe connects the output end of the sludge suction pump to the sludge storage tank, and a sludge suction hose is connected to the input end of the sludge suction pump. An anti-clogging mechanism is provided at the bottom end of the sludge suction hose. The anti-clogging mechanism includes a filter cartridge, a fixing ring, an L-shaped plate, a base plate, a screw knob, and a clamping plate. The fixing ring is fixedly connected to the bottom end of the outer wall of the sludge suction hose, and two L-shaped plates are movably connected to the outer wall of the fixing ring through rotating rods on both sides of the horizontal portion. The base plate is fixedly connected to the vertical portion of the L-shaped plate, and the screw knob is movably connected to a screw hole opened on the top surface of the base plate. The clamping plate is fixedly connected to the top end of the screw knob, and the filter cartridge is fixedly connected to the bottom end of the sludge suction hose through a connecting ring at the top end of the outer wall.

[0008] Preferably, a fixing ring is fixedly installed at the bottom of the outer wall of the suction hose, and a set of symmetrical positioning holes are opened on the top surface of the fixing ring.

[0009] Preferably, the outer wall of the fixing ring is provided with a set of symmetrical notches, and the inner walls of the notches are provided with rotation holes on both sides.

[0010] Preferably, rotating rods are fixedly installed on both sides of the horizontal portion of the L-shaped plate, and the rotating rods are movably installed in the rotating holes. A base plate is fixedly installed at the bottom of the inner side wall of the vertical portion of the L-shaped plate, and a screw hole is opened on the top surface of the base plate. A screw knob is threaded into the screw hole, and a clamping plate is fixedly installed at the top of the screw knob. A limit rod is fixedly installed at the top of the clamping plate.

[0011] Preferably, a connecting ring is fixedly installed on the top of the outer wall of the filter cartridge, and a set of symmetrical positioning rods are fixedly installed on the top surface of the connecting ring and inserted into the positioning hole. A set of symmetrical limiting holes are also opened on the top surface of the connecting ring, and the limiting rods are inserted into the limiting holes.

[0012] Preferably, the outer wall of the filter cartridge has several filter holes, and a cage-like protective cover is fixedly installed on the outer wall of the filter cartridge outside the filter holes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the anti-clogging mechanism allows the filter cartridge to be positioned and installed at the suction end of the suction hose after the positioning rod is inserted into the positioning hole. By rotating the L-shaped plate inwards with the rotating rod, the bottom plate is positioned below the connecting ring. Rotating the screw knob rotates the clamping plate upwards and pushes the limiting rod, inserting it into the limiting hole. The clamping plate then pushes the connecting ring to press the filter cartridge against the suction end of the suction hose, allowing for quick and secure installation of the filter cartridge and suction hose. The protective cover on the outer wall of the filter cartridge prevents plastic debris from adhering tightly to the filter cartridge wall and clogging the filter holes. The filter holes on the outer wall of the filter cartridge effectively filter larger solid debris such as stones, branches, and plastic bags from the sludge, preventing blockage of the suction hose and avoiding damage to the suction pump. This improves the dredging and cleaning effect on municipal drainage pipes. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 - Figure 4As shown, a municipal drainage pipe dredging device includes a dredging vehicle 1, a sludge storage tank 2 mounted on the dredging vehicle 1, and a sludge suction pump 3 fixedly connected to the top surface of the sludge storage tank 2. A connecting pipe 4 connects the output end of the sludge suction pump 3 to the sludge storage tank 2, and a suction hose 5 connects to the input end of the sludge suction pump 3. An anti-clogging mechanism 6 is provided at the bottom end of the suction hose 5, and the anti-clogging mechanism 6 includes a filter cartridge 7, a fixing ring 13, an L-shaped plate 17, a base plate 19, a screw knob 21, and a clamping plate 22. The fixed ring 13 is fixedly connected to the bottom of the outer wall of the suction hose 5, and the two L-shaped plates 17 are movably connected to the outer wall of the fixed ring 13 through the rotating rods 18 on both sides of the horizontal part. The bottom plate 19 is fixedly connected to the vertical part of the L-shaped plate 17, and the screw knob 21 is movably connected to the screw hole 20 opened on the top surface of the bottom plate 19. The clamping plate 22 is fixedly connected to the top of the screw knob 21. The filter cartridge 7 is fixedly connected to the bottom of the suction hose 5 through the connecting ring 10 at the top of the outer wall.

[0022] like Figure 4 As shown, a fixing ring 13 is fixedly installed at the bottom of the outer wall of the suction hose 5, and a set of symmetrical positioning holes 14 are opened on the top surface of the fixing ring 13. The positioning holes 14 opened on the top surface of the fixing ring 13 are used to cooperate with the positioning rod 11 to achieve positioning and installation of the filter cartridge 7.

[0023] like Figure 4 As shown, a set of symmetrical notches 15 are provided on the outer wall of the fixed ring 13, and rotating holes 16 are provided on both sides of the inner wall of the notch 15. The rotating holes 16 on both sides of the inner wall of the notch 15 are used to cooperate with the rotating rod 18 to realize the rotation operation.

[0024] like Figure 4 As shown, rotating rods 18 are fixedly installed on both sides of the horizontal part of the L-shaped plate 17, and the rotating rods 18 are movably installed in the rotating holes 16. A base plate 19 is fixedly installed at the bottom of the inner side wall of the vertical part of the L-shaped plate 17, and a screw hole 20 is opened on the top surface of the base plate 19. A screw knob 21 is threadedly connected in the screw hole 20, and a clamping plate 22 is fixedly installed at the top of the screw knob 21. A limiting rod 23 is fixedly installed at the top of the clamping plate 22. After the L-shaped plate 17 is flipped inward by rotating rod 18, so that the base plate 19 is placed below the connecting ring 10, the screw knob 21 in the screw hole 20 is rotated, so that the screw knob 21 rotates along the thread and moves upward until the screw knob 21 pushes the limiting rod 23 into the limiting hole 12 through the clamping plate 22 at the top. The filter cartridge 7 can be installed and fixed on the suction end of the suction hose 5. It is also convenient to disassemble when the filter cartridge 7 is damaged or needs to be cleaned.

[0025] like Figure 3As shown, a connecting ring 10 is fixedly installed on the top of the outer wall of the filter cartridge 7, and a set of symmetrical positioning rods 11 are fixedly installed on the top surface of the connecting ring 10 and inserted into the positioning hole 14. A set of symmetrical limiting holes 12 are also opened on the top surface of the connecting ring 10, and a limiting rod 23 is inserted into the limiting hole 12. By inserting the positioning rod 11 on the top surface of the connecting ring 10 into the positioning hole 14, the filter cartridge 7 can be positioned and installed on the suction end of the suction hose 5. After the limiting rod 23 is inserted into the limiting hole 12, the filter cartridge 7 can be fixed and limited on the suction end of the suction hose 5 for use, so as to ensure the stability of the filter cartridge 7 during use.

[0026] like Figure 3 As shown, the outer wall of the filter cylinder 7 has several filter holes 8. The filter cylinder 7 can filter larger solid waste in the sludge through the filter holes 8 on the outer wall. In addition, a cage-like protective cover 9 is fixedly installed on the outer wall of the filter cylinder 7 outside the filter holes 8. The protective cover 9 can intercept larger plastic waste and prevent larger plastic waste from being adsorbed on the outer wall of the filter cylinder 7 under the action of suction and causing blockage of the filter holes 8, so as to ensure the suction efficiency of sludge.

[0027] The specific operating principle of using the anti-clogging mechanism 6 in conjunction with the dredging vehicle 1 to dredge municipal drainage pipes is as follows:

[0028] Before dredging, the anti-clogging mechanism 6 is installed on the suction end of the suction hose 5. During installation, the positioning rod 11 on the top surface of the connecting ring 10 installed at the top of the outer wall of the filter cartridge 7 is inserted into the positioning hole 14 on the top surface of the fixing ring 13 installed at the bottom of the outer wall of the suction hose 5. This achieves the purpose of quickly positioning and installing the filter cartridge 7 on the suction end of the suction hose 5. The L-shaped plates 17 located on both sides of the fixing ring 13 are flipped inward. The lateral part of the L-shaped plate 17 will rotate within the notch 15 opened on both sides of the fixing ring 13, and the rotating rods 18 on both sides of the lateral part of the L-shaped plate 17 will be recessed in the notch 15. Rotate within the rotating holes 16 on both sides of the inner wall of the L-shaped plate 17. After the bottom plate 19 installed at the bottom of the inner side wall of the vertical part of the L-shaped plate 17 is placed below the connecting ring 10, rotate the screw knob 21 in the screw hole 20 on the top surface of the bottom plate 19. The screw knob 21 will rotate upward within the screw hole 20 and drive the top clamping plate 22 to rotate upward until the clamping plate 22 is pressed against the bottom surface of the connecting ring 10. The limiting rod 23 installed on the top surface of the clamping plate 22 is inserted into the limiting hole 12 on the top surface of the connecting ring 10. Therefore, the filter cartridge 7 can be fixedly installed on the output end of the suction hose 5 for use.

[0029] During dredging, the suction hose 5 is inserted into the municipal drainage pipe to be dredged, and the suction pump 3 installed on the top of the sludge tank 2 is turned on. The suction pump 3 will suck up the sludge in the municipal drainage pipe through the suction hose 5. When the sludge enters the suction hose 5, it will pass through the protective cover 9 installed on the outer wall of the filter cylinder 7. The protective cover 9 can intercept larger plastic bags and other plastic waste to the outside, preventing these wastes from adhering tightly to the outer wall of the filter cylinder 7 under the action of suction and clogging the filter holes 8 opened on the outer wall of the filter cylinder 7. 8 can further effectively filter larger solid waste such as stones, branches, and plastic bags in the sludge, preventing the suction hose 5 from being blocked by these wastes, and avoiding damage to the suction pump 3 caused by these wastes. This improves the sludge removal effect on municipal drainage pipes. The filtered sludge will enter the filter cartridge 7 through the filter hole 8, and then enter the suction hose 5 to be extracted. After that, it will be transported to the sludge storage tank 2 through the connecting pipe 4 installed on the output end of the suction pump 3 for storage.

[0030] When it is necessary to disassemble the filter cartridge 7, rotate the screw knob 21 in the opposite direction to move the limiting rod 23 out of the limiting hole 12 through the clamping plate 22, and then flip the L-shaped plate 17 outward to move the bottom plate 19 away from the bottom of the connecting ring 10. Then, the filter cartridge 7 can be directly removed from the bottom of the suction end of the suction hose 5, so that the filter cartridge 7 can be cleaned or replaced.

[0031] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
