Description

Technical Field

[0001] The utility model belongs to the field of pipeline dredging devices, in particular to a stepped water conservancy pipeline clogging dredging device. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the street or anywhere else, as long as they are pipes that play a role in drainage, they should be counted as drainage pipes. In the use of drainage pipes, they are usually mixed with sludge. Due to the long-term accumulation of sludge, the drainage pipes are blocked by sludge. The existing drainage pipe sludge dredging devices have complex structures and single functions, resulting in poor dredging effects. At present, the existing equipment for dredging pipeline sludge is mostly to squeeze the sludge to make it move and discharge it from the other end of the pipeline. If there is too much sludge accumulation in the pipeline or the sludge accumulation forms lumps, the dredging action requires great pressure to achieve a stable and effective dredging effect. Therefore, it is not suitable for pipes blocked by high-density sludge. The common improvement method is to stir and hit the sludge or lumps to keep them loose, so as to reduce the pressure required to push and discharge the sludge, but it can only deal with the sludge and lumps near the front of the equipment, and the continuous accumulation of broken lumps will still increase the pressure required to push the sludge out of the pipeline. The drill bit is stuck and scrapped, which affects work efficiency, brings a series of problems to actual production, and also increases production costs. The existing technology uses a flat end face dredging device, and the silt drainage ditch has no or is too small, resulting in poor silt drainage and easy blockage; since the end face is flat and there is no positioning core, it will deviate, and the dredging device will directly contact the inner wall of the pipe, causing damage to the inner wall of the pipe. Utility Model Content

[0003] (1) Technical problem to be solved: In view of the defects of existing dredging devices that are difficult to position during the dredging process and are prone to deviation, thus damaging the pipeline, the utility model provides a stepped water conservancy pipeline dredging device that is not prone to deviation.

[0004] (2) The technical solution adopted by the utility model is as follows:

[0005] A stepped water conservancy pipeline clogging dredger comprises a dredger body, a connecting portion is arranged at the tail end of the dredger body, a multi-step surface is arranged at the head of the dredger body, a plurality of crushing ball teeth are evenly distributed on each step surface, a plurality of wings are arranged at the head of the dredger body, the crushing ball teeth are evenly distributed on the plurality of wings, and a silt drainage ditch is arranged between two adjacent wings.

[0006] A further technical solution is to provide a loading and unloading platform at the rear of the dredger body.

[0007] A further technical solution is that an exhaust groove is provided at the edge of the wing and between the two crushing ball teeth.

[0008] A further technical solution is that a high-pressure air hole is provided at the root of the drainage ditch, and the high-pressure air hole is connected to the buffer zone of the inner cavity of the dredging device body.

[0009] A further technical solution is that the connection portion is provided with a trapezoidal reverse thread in the inner cavity at the rear end of the dredge body for connecting with the drill rod.

[0010] A further technical solution is that the wing portion includes six, and the head of the dredger body forms a six-wing structure.

[0011] A further technical solution is that the transition angle between the wing and the tail of the dredge body is 35°-55°.

[0012] (3) Due to the adoption of the above technical solution, the beneficial effect of the utility model is as follows: by arranging a multi-step surface on the head of the dredger body, and a number of crushing ball teeth are evenly distributed on each step surface, in the process of connecting the utility model to the drill rod for dredging, the multi-step surface arranged on the head of the dredger body will form holes of corresponding shapes on the blockage, so that the head of the dredger body is not easy to deviate and can position itself, avoiding the problem that the dredger deviates and is difficult to position in actual work, causing damage and damage to the wall of the drainage pipe hole. The head of the dredger body is provided with a plurality of wings, and the crushing ball teeth are evenly distributed on the plurality of wings. A silt drainage ditch is provided between two adjacent wings, and the drilled blockage will be discharged along the silt drainage ditch to the tail of the dredger body, ensuring that the dredger continues to move forward.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-Figure 4 shown.

[0019] A stepped water conservancy pipeline clogging dredger comprises a dredger body 1, a connecting portion is arranged at the tail end of the dredger body 1, a multi-step surface 3 is arranged at the head of the dredger body 1, a plurality of crushing ball teeth 4 are evenly distributed on each step surface 3, a plurality of wings 5 ​​are arranged at the head of the dredger body 1, the crushing ball teeth 4 are evenly distributed on the plurality of wings 5, and a silt drainage ditch 6 is arranged between two adjacent wings 5.

[0020] When in use, the connection part at the tail end of the clearing machine body 1 is used to connect with the drill rod of the existing drilling rig, and then the clearing machine is placed in the pipeline. After the clearing machine contacts the blockage, the position of the clearing machine is pre-positioned, and the drilling rig is started to continue to push the clearing machine. As the clearing machine rotates, the multi-step surface 3 arranged on the head of the clearing machine body 1 will form holes of corresponding shapes on the blockage, so the head of the clearing machine body 1 is not easy to deviate, and the drilled blockage will be discharged to the tail end of the clearing machine body 1 along the drainage ditch 6. The clearing machine is continued to be pushed until the clearing work is completed. The connection part is a trapezoidal reverse-rotating thread 10 for connecting with the drill rod is provided in the inner cavity at the tail end of the clearing machine body 1, and the wing 5 includes six, and the head of the clearing machine body 1 forms a six-wing structure. The transition angle between the wing 5 and the tail of the dredge body 1 is 35°-55°, and the crushing ball teeth 4 are cold pressed into the blind hole of the multi-step surface 3 through interference tolerance, and the interference amount is 0.15-0.25mm; when the crushing ball teeth 4 fall off, new ball teeth can be pressed in again for continued use.

[0021] A loading and unloading platform 2 is arranged at the tail of the dredge body 1, which is equivalent to a keyway pin. After the tail of the body is inserted into the drill pipe, it is locked with a latch to prevent the tail of the body from rotating and slipping in the drill pipe. The loading and unloading platform 2 and the connecting part are two different ways of connecting with the drill pipe.

[0022] An exhaust groove 7 is provided at the edge of the wing 5 and between the two crushing ball teeth 4. The function of the exhaust groove 7 is to timely remove the silt and slag between the two crushing ball teeth and reduce the weight of the drill body.
