Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging, in particular to a pipeline dredging device for municipal engineering. Background Art

[0002] Municipal infrastructure projects refer to the civil engineering, pipeline and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardening, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities and ancillary facilities. Among them, municipal pipelines are used in the field of urban drainage, including rainwater discharge, sewage treatment and sludge treatment. Municipal companies will lay various drainage pipelines in the city to ensure that rainwater and sewage in the city are treated and discharged in a timely manner.

[0003] When sewage or sludge is discharged through municipal pipelines, the sediment contained in the sewage or sludge will gradually settle in the pipeline during the flow process, thus forming a sludge layer in the pipeline. Especially when the flow rate in the pipeline is slow or the discharge is scheduled, the flow effect of the sludge decreases, so that the sedimentation of sludge in the pipeline is more serious.

[0004] When sludge accumulates in municipal pipelines, the method of unclogging the pipelines usually requires manual use of tools to hook out the silt layer. During the unclogging process, manual work is required to constantly observe the blockage location and perform corresponding cleaning actions. The unclogging method is relatively laborious and it is difficult to improve the efficiency of unclogging the pipelines. Utility Model Content

[0005] The purpose of the utility model is to provide a pipeline dredging device for municipal engineering in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pipeline dredging device for municipal engineering, comprising a circular body, six sliding wheels annularly arranged on the circular body for allowing the circular body to move horizontally in the pipeline, a rotating column rotatably arranged on the left side of the circular body, a rotating motor for driving the rotating column to rotate, a fixed end arranged at the left end of the circular body and an output end connected to the right end of the rotating column, at least two fixed seats annularly equidistantly arranged on the rotating column, sliding holes respectively opened on each of the fixed seats, sliding rods respectively slidably arranged on each of the fixed seats and located in the sliding holes, a return spring arranged between one end of each of the sliding rods and the fixed seat and located in the sliding hole, a cutting block arranged at the other end of each of the sliding rods, an anti-slip member arranged between each of the sliding rods and the fixed seat for preventing the sliding rod from slipping out of the sliding hole, and a pushing handle arranged on the right end face of the circular body.

[0007] A further improvement is that the anti-dropping member comprises a guide opening formed on the fixing seat and connected to the sliding hole, and a guide block provided on the peripheral side of the sliding rod and having a clearance fit with the guide opening.

[0008] A further improvement is that six mounting seats are equidistantly arranged in a ring on the circular body, each mounting seat is provided with an adjustment opening, each mounting seat is provided with an adjustment rod which can be raised and lowered in the adjustment opening, an extrusion spring is provided between one end of each adjustment rod and the mounting seat, the extrusion spring is located in the adjustment opening, and each sliding wheel is rotatably arranged at the other end of the adjustment rod.

[0009] A further improvement is that: the return spring is a tension spring.

[0010] Further improvements are: a water flow groove is provided in a ring shape on the circular body, the water flow groove is close to the left side of the circular body, a plurality of water spray heads are provided in a ring shape on the left end face of the circular body, each water spray head is connected to the water flow groove, a water inlet hole is provided on the right end face of the circular body, the left end of the water inlet hole is connected to the right end of the water flow groove, and a connecting head is provided on the right end face of the circular body at the end of the water inlet hole, the connecting head is used to be connected and fixed to an external water pipe, and the connecting head is connected to the water inlet hole.

[0011] A further improvement is that an anti-slip ring is provided on the outer periphery of the connector.

[0012] A further improvement is that the anti-slip ring is a rubber ring.

[0013] A further improvement is that the pushing handle includes a fixed column arranged on the right end surface of the circular body, a sliding opening opened on the fixed column, a telescopic rod slidably arranged on the fixed column and located in the sliding opening, a driving disk arranged on the right end surface of the telescopic rod, and a fixing member arranged between the fixed column and the telescopic rod for fixing the telescopic rod in the sliding opening.

[0014] A further improvement is that the fixing member includes a threaded hole opened on the peripheral side of the fixing column and a fixing bolt threadedly connected to the threaded hole, and the threaded hole is located on the peripheral side of the right end of the fixing column.

[0015] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when there is sludge accumulation in the municipal pipeline, the circular body is first put into the pipeline opening until each sliding wheel contacts the inner wall of the pipeline, thereby supporting the circular body in the pipeline, and then starting the rotating motor to drive the rotating column to rotate. During the rotation of the rotating column, the sliding rod is caused to slide outward in the sliding hole by the action of centrifugal force, so that each cutting block is closer to the inner wall of the pipeline, and the anti-slip part is used to prevent the sliding rod from slipping out of the sliding hole due to the centrifugal force. As the rotating column rotates, the cutting blocks are driven to move together. At this time, it is only necessary to push the circular body in the direction of the sludge layer, and the rotating cutting blocks will chop the sludge layer. After the processing is completed, the rotating motor is turned off, and the pushing handle is pulled outward to pull the circular body out to complete the dredging process. This method of dredging the pipeline is more labor-saving and can improve the dredging efficiency of the pipeline.

[0016] Further effect: when the six sliding wheels abut against the inside of the pipe, a force is applied to the adjusting rod toward the inner wall of the pipe by squeezing the spring, thereby increasing the abutment force between the sliding wheels and the inner wall of the pipe, and preventing a gap between the sliding wheels and the inner wall of the pipe from affecting the movement of the circular body; when the circular body needs to be placed in the pipe, a part of the sliding wheels is first placed in the pipe, and the pipe is pressed to allow the other part of the sliding wheels to enter the pipe, which makes it easier for the circular body to be placed in the pipe.

[0017] Further effect: when the cutting block breaks up the silt layer, water is transported to the water flow trough through the water inlet hole through the external water pipe, and then the water is sprayed out from several sprinkler heads, thereby wetting the agglomerated silt layer, reducing the hardness of the agglomerates and improving the dredging effect on the silt layer.

[0018] Further effect: after the water pipe is inserted into the connector, the anti-slip ring and the inner wall of the water pipe are squeezed to tighten the water pipe on the connector, thereby improving the stability of the water pipe and the connector.

[0019] Further effect: Through the deformation effect of the rubber material, the tensioning effect with the inner wall of the water pipe can be improved, and the sealing between the water pipe and the connecting head can be improved after being connected with the water pipe.

[0020] Further effect: after the circular body is placed in the pipeline, the telescopic rod is pulled outward to increase the control distance between the telescopic rod and the fixed column, and then the fixing bolt is screwed into the threaded hole until the fixing bolt is pressed against the surface of the telescopic rod, thereby fixing the telescopic rod in the sliding opening, allowing the operator to push the circular body deep into the pipeline to dredge the silt layer at some depths.

[0046] The push handle includes a fixed column 21 arranged on the right end surface of the circular body 1, a sliding opening 22 opened on the fixed column 21, a telescopic rod 23 slidably arranged on the fixed column 21 and located in the sliding opening 22, a driving disk 24 arranged on the right end surface of the telescopic rod 23, and a fixing member arranged between the fixed column 21 and the telescopic rod 23 for fixing the telescopic rod 23 in the sliding opening 22.

[0048] The working principle of the utility model is as follows: when there is sludge accumulation in the municipal pipeline, the circular body 1 is first put into the pipeline opening until each sliding wheel 2 contacts the inner wall of the pipeline, thereby supporting the circular body 1 in the pipeline, and then starting the rotating motor 4 to drive the rotating column 3 to rotate. During the rotation of the rotating column 3, the sliding rod 7 slides outward in the sliding hole 6 through the action of centrifugal force, so that each cutting block 9 is closer to the inner wall of the pipeline, and the sliding rod 7 is prevented from slipping out of the sliding hole 6 due to the centrifugal force through the cooperation of the guide opening 10 and the guide block 11. As the rotating column 3 rotates, the cutting blocks 9 are driven to move together. At this time, it is only necessary to push the circular body 1 in the direction of the silt layer, and the rotating cutting blocks 9 chop the silt layer. After the processing is completed, turn off the rotating motor 4, and pull the pushing handle outward to pull out the circular body 1 to complete the dredging process. This is a more labor-saving way to dredge the pipeline, and can improve the dredging efficiency of the pipeline.

[0049] When the six sliding wheels 2 are in contact with the pipe, the adjusting rod 14 is forced toward the inner wall of the pipe by squeezing the spring 15, thereby increasing the contact force between the sliding wheels 2 and the inner wall of the pipe, and preventing a gap between the sliding wheels 2 and the inner wall of the pipe from affecting the movement of the circular body 1. When the circular body 1 needs to be placed in the pipe, a part of the sliding wheels 2 is first placed in the pipe, and the pipe is pressed to allow the other part of the sliding wheels 2 to enter the pipe, which facilitates the placement of the circular body 1 in the pipe.

[0050] When the cutting block 9 breaks up the silt layer, water is delivered to the water flow channel 16 through the water inlet hole 18 through the external water pipe, and then the water is sprayed out from a plurality of water spray heads 17, thereby wetting the agglomerated silt layer, reducing the hardness of the agglomerates and improving the dredging effect on the silt layer;

[0051] After the circular body 1 is placed in the pipeline, the telescopic rod 23 is pulled outward to increase the control distance between the telescopic rod 23 and the fixing column 21, and then the fixing bolt 26 is screwed into the threaded hole 25 until the fixing bolt 26 is pressed against the surface of the telescopic rod 23, thereby fixing the telescopic rod 23 in the sliding opening 22, so that the operator can push the circular body 1 deeply into the pipeline to dredge the silt layer at some depth.
