Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging, and more specifically, to a drainage pipeline dredging device for a municipal engineering project. Background Art

[0002] Municipal pipelines are one of the important components of urban infrastructure, which can timely discharge urban ground rainwater and domestic sewage. Since the drainage pipelines of municipal projects are mostly unpowered pipelines, the slope of the pipelines is used to provide the power of water flow. Rainwater and sewage contain a lot of silt and debris. During the drainage process, the silt and debris in the rainwater and sewage are easy to deposit in the drainage pipelines. Long-term deposition will cause blockage inside the drainage pipelines. Therefore, it is necessary to regularly clear and dredge the drainage pipelines.

[0003] The commonly used cleaning method is to use a high-pressure nozzle driven by a high-pressure pump to penetrate the pipe for flushing. The principle is that water is transported to the high-pressure nozzle through the high-pressure pipeline. A small diameter hole is opened on the back of the high-pressure nozzle to form a high-pressure and high-speed jet. The water sprayed backward will generate a thrust on the nozzle, pushing the nozzle to drive the high-pressure water pipe forward. At the same time, the high-pressure water will flush and dredge the drainage pipe wall and take the debris out of the pipe.

[0004] During pipeline dredging operations, it is necessary to open the drain manhole cover and place the high-pressure nozzle into the drain manhole. After the high-pressure pump starts working, the water flow will reverse and spray the blockage from the inside of the drain pipe to the outside. Sewage containing microorganisms and domestic garbage will splash onto the workers from the drain manhole. The workers need to work continuously and there is a chance of infection if they do not have time to clean up in time. Therefore, the sanitary environment of the operation needs to be guaranteed.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a municipal engineering drainage pipe dredging device. Utility Model Content

[0013] Preferably, the blocking block belongs to a supporting structure, and the supporting structure is used to support the inlet of the drainage well to prevent the auxiliary pipe from being dragged into the drainage well by the recoil force generated by the high-pressure water flow.

[0034] like Figure 1-3 As shown, a municipal engineering drainage pipe dredging device includes a high-pressure nozzle 1 that sprays high-pressure water backwards to dredge the drainage pipe. The high-pressure nozzle 1 is connected to a high-pressure water tank 3 through a delivery pipe 2. The high-pressure water tank 3 is used to provide power and water source for the high-pressure nozzle 1.

[0035] The delivery pipeline 2 is outer-connected with an auxiliary pipe 4, which is used to prevent the delivery pipeline 2 from being damaged by friction with the drainage wellhead when it is pulled forward by the high-pressure nozzle 1;

[0036] When it is necessary to dredge the pipeline, set an auxiliary sign at the drainage well mouth to prevent pedestrians from entering by mistake and causing danger. After opening the drainage well cover at the blocked part, set the auxiliary pipe 4 outside the delivery pipe 2, and extend a part of the auxiliary pipe 4 into the drainage well, and then lower the high-pressure nozzle 1 into the drainage well;

[0037] The supporting structure 6 is used to support the inlet of the drainage well to prevent the auxiliary pipe 4 from being dragged into the drainage well by the recoil force generated by the high-pressure water flow;

[0038] The supporting structure 6 includes a positioning block 62, a supporting plate 61 and a leg 63. The positioning block 62 is fixed on the surface of the supporting plate 61. The leg 63 is distributed in a circle around the surface of the auxiliary pipe 4. One end of the supporting plate 61 is rotatably connected to the leg 63 by providing a rotation groove 611.

[0039] In the initial state, the support plate 61 naturally hangs down and fits the surface of the auxiliary pipe 4. When in use, ensure that the legs 63 are located above the drainage wellhead, and rotate the support plate 61 upward. The support plate 61 rotates upward with the rotation connection with the legs 63 as the rotation center.

[0040] A limit guard plate 612 is provided on one side of the rotating groove 611 which is horizontally upward, and is used to limit the rotation angle of the supporting plate 61, so that the supporting plate 61 can rotate up to 90 degrees to a flattened state. It is worth noting that the outer diameter of the supporting plate is larger than the inner diameter of the drainage well inlet, so that after the auxiliary pipe 4 is naturally lowered, the supporting plate 61 can be flattened and stuck on the drainage well mouth;

[0041] Therefore, by providing a supporting mechanism, the high-pressure nozzle 1 can be supported at the drainage well mouth when the back-jet water flow generates recoil, so as to prevent the auxiliary pipe 4 from being pulled by the delivery pipe 2 and falling into the drainage well;

[0042] A shielding mechanism 5 is installed on the outside of the auxiliary pipe 4 to shield the sewage brought out by the reverse spraying of water from the high-pressure nozzle 1;

[0043] The shielding mechanism 5 includes an umbrella cloth 51, a hinge rod 52, a support rod 53 and a top ring 56. The top ring 56 is sleeved on the surface of the auxiliary tube 4. The side of the top ring 56 is rotatably connected to the hinge rod 52 in a circumferential distribution. The hinge rod 52 is fixed to the shielding surface of the umbrella cloth 51 by sewing thread as a supporting skeleton. The hinge rod 52 is rotatably connected to the support rod 53 by a connecting handle 55. One end of the support rod 53 connected to the hinge rod 52 is a rotating end, and the other end is a supporting end.

[0044] The support end of the support rod 53 is provided with an elbow 54 of a bent structure, and the elbow 54 is movably inserted into the positioning hole 621, and the positioning hole 621 is provided in the positioning block 62, and the positioning block 62 is used to limit the elbow 54 so that the shielding mechanism 5 remains in the open state;

[0045] In the natural state, the umbrella cloth 51 and the hinge rod 52 are folded downward and attached to the surface of the auxiliary tube 4, and cover the supporting structure 6 in the folded state;

[0046] After the supporting mechanism is flattened, the auxiliary pipe 4 can be pulled upward, and the supporting plate 61 rotates under natural gravity with the connection with the supporting legs 63 as the rotation center, and the supporting plate 61 tilts downward;

[0047] As attached Figure 2 As shown, the positioning block 62 is arranged at the position of the supporting plate 61 close to the auxiliary pipe 4, and the supporting plate 61 is tilted downward, and the positioning block 62 thereon is no longer close to the surface of the auxiliary pipe 4, but gradually opens outward. At this time, the elbows 54 of the support rods 53 are correspondingly inserted into the positioning holes 621 of the positioning blocks 62 at their respective positions, and the support rods 53 are propped up obliquely. The support rods 53 push the hinge rods 52 upward through the connecting handles 55, and the ends of the hinge rods 52 are rotatably connected to the top ring 56, and the top ring 56 is sleeved on the surface of the auxiliary pipe 4. The ends of the hinge rods 52 rotate around the connection between the two, and the hinge rods 52 are pushed upward by the support rods 53 to unfold, and the umbrella cloth 51 is stretched upward by the hinge rods 52 distributed circumferentially and covers the drainage wellhead;

[0048] Therefore, by setting a positioning plate on the supporting structure 6, the support rod 53 of the shielding mechanism 5 is limited, so as to achieve the technical effect of assisting the umbrella cloth 51 to be opened;

[0049] At this point, the preliminary preparation work is completed. At this time, the power source of the high-pressure water tank 3 is turned on again, and the water flows along the delivery pipe 2 to the high-pressure nozzle 1, and then sprayed backwards by the high-pressure nozzle 1. It should be noted that there is a gap between the umbrella cloth 51 and the auxiliary pipe 4 to avoid blocking the air circulation at the drainage wellhead to form a negative pressure to suck the umbrella cloth 51 into it. The high-pressure nozzle 1 will disperse the blockage and spray it out, and the sewage will be blocked by the opened umbrella cloth 51. The recoil force will carry the delivery pipe 2 to continuously extend into the drainage pipe, and finally the drainage pipe will be unblocked;

[0050] By arranging a shielding mechanism 5 outside the auxiliary pipe 4 that prevents the auxiliary delivery pipe 2 from being stuck, when sewage is sprayed out from the drainage well, the hinge rod 52 can be propped up by the support rod 53, and the hinge rod 52 can open the umbrella cloth 51, and the umbrella cloth 51 can shield the drainage well mouth, so as to achieve the technical effect of preventing sewage from splashing onto the staff, thereby solving the problem that the water flow is reversed and the blockage is sprayed out from the drainage pipe, and the sewage containing microorganisms and domestic garbage will splash onto the staff from the drainage well, and the staff needs to work continuously, and there is a probability of infection if there is no time to clean it in time;

[0051] When the strong force pulls the delivery pipe 2 forward, it will also drive the auxiliary pipe 4 to move toward the drainage well, and the support plate 61 is limited by the limit guard plate 612, and the support plate 61 will not continue to rotate upward, but will be stuck at the drainage well mouth. To achieve this effect, the material structure of the rotating connection and the limit guard plate 612 must have a certain strength to prevent the support plate 61 from being broken due to excessive recoil.

[0052] After the dredging operation, the high-pressure nozzle 1 is recovered from the drainage pipe by pulling the delivery pipe 2 back, and then the auxiliary pipe 4 is lifted upward, the support plate 61 naturally hangs down under the action of gravity, the positioning block 62 opens outward, and the elbow 54 of the support rod 53 is taken out from the corresponding positioning holes 621, and the support rod 53, the hinge rod 52 and the umbrella cloth 51 all hang down naturally, thus completing the folding process;

[0053] The shielding mechanism 5 and the supporting structure 6 can be folded and stored to save transportation space, and can be quickly opened when in use to improve use efficiency.

[0054] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
