Description

Technical Field

[0001] The utility model relates to the field of municipal pipelines, and specifically relates to a municipal pipeline dredging device. Background Technique

[0002] As an important part of urban infrastructure, municipal pipelines include drainage pipelines, which are mainly used to collect sewage, rainwater and industrial wastewater in the city and transport them to sewage treatment plants or other treatment facilities for treatment. Drainage pipelines are of great significance for urban flood control and environmental protection.

[0003] However, with the increase of the service life of the pipeline, phenomena such as wear, corrosion or scaling may occur on the inner wall of the pipeline, which will increase the possibility of silt deposition in the pipeline. Moreover, in the rainy season, a large amount of sediment and garbage carried by rainwater may enter the municipal pipeline through the rainwater inlet, increasing the generation amount of silt in the pipeline, and causing the pipeline to be blocked by silt over time.

[0004] When the pipeline is blocked by silt, most of them use the method of high-pressure water guns to remove silt. By spraying water with high-pressure water guns, the accumulated substances are washed out of the pipeline. Although this method can handle pipelines of various shapes and specifications, the cost is relatively high, and it may cause certain damage to the pipeline wall. Content of the Utility Model

[0005] The purpose of the utility model is to provide a municipal pipeline dredging device, which effectively solves the problem that in the process of removing silt from municipal pipelines, when using the high-pressure water gun dredging method, the impact on the pipeline wall may cause certain damage to the pipeline.

[0006] The technical solution of the utility model is as follows:

[0007] A municipal pipeline dredging device includes a main pipeline and a branch pipeline. The branch pipeline is vertically distributed on the main pipeline and is connected to it. A baffle is provided at the top of the branch pipeline. An elevator plate is provided inside the branch pipeline. An elevating assembly is provided between the elevator plate and the baffle. Silt suction pipes are symmetrically provided on the elevator plate. One end of the silt suction pipe extends below the elevator plate, and the other end of the silt suction pipe extends out of the baffle. A stirring column is provided below the elevator plate. Stirring shafts are evenly distributed on the outer wall of the stirring column. A motor is provided at the top of the elevator plate, and the output shaft of the motor is connected to the stirring shaft. Sprayers are symmetrically provided below the elevator plate, and a water delivery pipe vertically passing through the baffle is provided on the sprayer.

[0008] Furthermore, the cross-sections of the baffle and the elevator plate are circular, and the diameter of the baffle is not less than the diameter of the branch pipeline. The outer wall of the elevator plate matches the inner wall of the branch pipeline.

[0009] Further, the lifting assembly includes a lifting rope, a mating wheel, and a handle. The lifting ropes are symmetrically arranged at the top of the lifting plate. The lifting ropes pass through the baffle. The mating wheel is connected above the baffle through a mounting plate. The lifting ropes are movably attached to the wheel wall of the mating wheel. The other end of the lifting rope is fixedly connected to a handle.

[0010] Further, a buffer block is provided below the stirring column. The vertical cross-section of the buffer block is arc-shaped. A buffer spring is provided between the buffer block and the stirring column.

[0011] Further, a downward guiding groove is provided at the top of the stirring column. The cross-section of the guiding groove is circular. The inner wall of the guiding groove is provided with outward limiting grooves distributed in a ring shape.

[0012] Further, annularly distributed positioning strips are provided on the outer wall of the output shaft of the motor near the bottom. Above the positioning strips, there is a threaded connection part on the output shaft. A threaded locking ring is provided on the output shaft and above the stirring column. After the output shaft is inserted into the guiding groove, the threaded locking ring connects the output shaft to the stirring shaft.

[0013] The advantages of the present utility model are as follows:

[0014] 1. By providing a baffle at the top of the branch pipeline in the present utility model, the lifting plate is movably arranged inside the branch pipeline. There is a silt suction pipe on the lifting plate. When starting, one end of the water delivery pipe is connected to a water tank. The water in the water tank will be sprayed out from the nozzle through the water delivery pipe to dilute the silt, and then the silt will be sucked away through the suction of the silt suction pipe. Compared with the original method using a high-pressure water gun, it effectively protects the municipal pipeline and avoids damage to the municipal pipeline.

[0015] 2. By arranging a stirring column between two silt suction pipes below the lifting plate in the present utility model, there is a stirring shaft connected to the stirring column. The silt is stirred through the stirring shaft, so that the water can be better diluted with the silt, and the silt suction pipe can suck away the silt faster, improving the efficiency of pipeline dredging.

[0016] 3. By providing a buffer block and a buffer spring at the bottom of the stirring column in the present utility model, when the amount of silt being sucked away decreases, the lifting plate descends inside the branch pipeline and finally reaches the main pipeline. The buffer block will eventually contact the inner wall of the main pipeline, so that the staff can know and avoid the stirring shaft rotating and touching the main pipeline, thus causing damage to the pipeline.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] As Figures 1 to 5 shown, the present utility model provides a municipal pipeline dredging device, which includes a main pipeline 1 and a branch pipeline 2. The branch pipeline 2 is vertically distributed on the main pipeline 1 and is connected to it. A baffle 3 is provided at the top of the branch pipeline 2. By means of the provided baffle 3, the silt suction pipe 5 and the water delivery pipe 11 can enter the interior of the branch pipeline 2.

[0025] A lifting plate 4 is provided inside the branch pipeline 2. Through the cooperation of the provided lifting rope 12, the lifting plate 4 can change its height inside the branch pipeline 2, so that it can also descend when the silt decreases.

[0026] A lifting assembly is provided between the lifting plate 4 and the baffle 3. Silt suction pipes 5 are symmetrically provided on the lifting plate 4. One end of the silt suction pipe 5 extends below the lifting plate 4, and the other end of the silt suction pipe 5 extends out of the baffle 3. By means of the provided silt suction pipe 5, the other end of the silt suction pipe 5 is connected to a silt box. The suction generated by the silt suction pipe 5 can suck the silt away and transport it into the silt box, thereby realizing the rapid cleaning of the silt.

[0027] A stirring column 6 is provided below the lifting plate 4. The outer wall of the stirring column 6 is provided with uniformly distributed stirring shafts 7. Through the cooperation of the provided stirring column 6 and the stirring shafts 7, when the silt is relatively dry, the silt can be broken up, so that the silt suction pipe 5 can better suck and transport the silt.

[0028] A motor 8 is provided at the top of the lifting plate 4. The output shaft 9 of the motor 8 is connected to the stirring shaft 7. Symmetrically arranged below the lifting plate 4 are spray nozzles 10. A water delivery pipe 11 vertically penetrating through the baffle 3 is provided on the spray nozzle 10. The other end of the water delivery pipe 11 is connected to a water tank with a water pump, and the water in the water tank can be sprayed out from the spray nozzle 10 through the water delivery pipe 11 to dilute the sludge, so that the sludge can be pumped away better.

[0029] The cross-sections of the baffle 3 and the lifting plate 4 are circular, and the diameter of the baffle 3 is not less than the diameter of the branch pipeline 2, so that the baffle 3 can cover the top of the branch pipeline 2, making it difficult for the toxic gas in the branch pipeline 2 to leak out, thus ensuring the safety of the dredging workers.

[0030] The outer wall of the lifting plate 4 is matched with the inner wall of the branch pipeline 2, enabling the lifting plate 4 to change its height within the branch pipeline 2.

[0031] The lifting assembly includes a lifting rope 12, a mating wheel 13 and a handle 14. The lifting ropes 12 are symmetrically arranged at the top of the lifting plate 4. The lifting ropes 12 pass through the baffle 3. The mating wheel 13 is connected above the baffle 3 through a mounting plate. The lifting ropes 12 are movably attached to the wheel wall of the mating wheel 13. The other end of the lifting rope 12 is fixedly connected to the handle 14. By means of the provided lifting assembly, the height change of the lifting plate 4 within the branch pipeline 2 can be controlled manually, and the height of the lifting plate 4 can be adjusted flexibly.

[0032] A buffer block 15 is provided below the stirring column 6. The vertical cross-section of the buffer block 15 is arc-shaped. A buffer spring 16 is provided between the buffer block 15 and the stirring column 6. When the stirring column 6 enters the interior of the main pipeline 1 and moves downward, the buffer block 15 will contact the bottom of the main pipeline 1. Under the limit of the buffer spring 16, the stirring column 6 can be effectively prevented from moving downward, protecting the main pipeline 1.

[0033] A downward guiding groove 17 is provided at the top of the stirring column 6. The cross-section of the guiding groove 17 is circular. The inner wall of the guiding groove 17 is provided with outwardly distributed limiting grooves 18 along the ring. Annularly distributed positioning strips 19 are provided on the outer wall near the bottom of the output shaft 9 of the motor 8. Above the positioning strips 19 is a threaded connection part 20 on the output shaft 9. A threaded locking ring 21 is provided on the output shaft 9 and above the stirring column 6. After the output shaft 9 is inserted into the guiding groove 17, the threaded locking ring 21 connects the output shaft 9 to the stirring shaft 7. By designing the stirring column 6 and the output shaft 9 to be movably detachable, after the sludge in the pipeline is cleaned, the stirring column 6 can be separated, so that the sludge on the stirring column 6 and the stirring shaft 7 can be cleaned.

[0034] The detailed usage method and functions of the above embodiments:

[0035] Generally, most of the silt accumulates at the intersection of the main pipeline 1 and the branch pipeline 2. When it is necessary to clean the silt, first, the two sides of the silt accumulation area of the branch pipeline 2 are sealed, the top of the pipe orifice at the silt accumulation area is opened, the lifting plate 4 is placed inside the branch pipeline 2, and the baffle plate 3 is placed on the top of the branch pipeline 2. In the initial state, one end of the water delivery pipe 11 is connected to a water tank, and the water in the water tank will be sprayed out from the nozzle 10 through the water delivery pipe 11 and sprayed on the silt to dilute the silt to a certain extent. The motor 8 is started, and the output shaft 9 of the motor 8 drives the stirring column 6 to rotate. There is a surrounding stirring shaft 7 outside the stirring column 6 to stir the silt. When the two dredging pipes 5 on both sides come into contact with the silt, the silt will be pumped away and transported to the silt box. When the silt is gradually pumped away, the handle 14 cooperates with the lifting rope 12 to descend on the cooperating wheel 13, so that the lifting plate 4 descends inside the branch pipeline 2 to realize the gradual pumping of the silt. When continuously pumping, after the lifting plate 4 enters the inside of the main pipeline 1, there is a buffer block 15 at the bottom of the stirring column 6. After the buffer block 15 contacts the bottom of the main pipeline 1, the lifting plate 4 will no longer descend, ensuring that the stirring shaft 7 will not damage the main pipeline 1.

[0036] When the silt in the pipeline is almost pumped away, the baffle plate 3 is removed, and the lifting plate 4 is taken out of the branch pipeline 2 through the lifting rope 12. The threaded locking ring 21 is screwed, so that the threaded locking ring 21 moves upward on the threaded connection part 20, and the positioning strip 19 will disengage from the limiting groove 18, so that the output shaft 9 can be separated from the stirring column 6, and the stirring column 6 can be cleaned, completing the cleaning work of the silt blockage in the pipeline.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
