Description

Technical Field

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

[0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewer pipes". In engineering, they are usually called municipal drainage pipes. However, during the long-term use of the pipes, some garbage and silt will block the pipes. It is necessary to use dredging devices to dredge the pipes in time to ensure normal production and life.

[0003] However, in the process of using the unclogging device in the prior art, a plurality of high-pressure water flows are usually used to drive the nozzle to enter the pipeline, and the high-speed water flow is used to flush the inside of the pipeline. The water consumption is large during use, and when encountering a hard blockage, the nozzle cannot rotate and is easily stuck by the blockage, resulting in low unclogging efficiency.

[0004] And the way to discharge the blockage is to use high-pressure water flow to remove the blockage through the recovery nozzle, so the nozzle must be recovered periodically to discharge the blockage, which undoubtedly increases the workload and makes it difficult to discharge the blockage during the dredging process;

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a municipal engineering drainage pipe dredging device, which, through the set dredging components, can adapt to a variety of hardness blockages and also discharge the blockages during the dredging process to solve the technical defects proposed by the background technology.

[0007] The purpose of the utility model can be achieved through the following technical scheme: a municipal engineering drainage pipe dredging device, including a shell, a motor is fixedly installed inside the shell, a fixed block is fixedly installed at the bottom of the shell, a control button is fixedly installed on the fixed block, a fixed pipe is fixedly installed at one end of the shell, a cavity is arranged inside the fixed pipe, a dredging component is movably installed in the fixed pipe, a slag discharge port is opened at the bottom of the fixed pipe, the slag discharge port is arranged close to the shell, and a push plate is fixedly installed on the fixed pipe.

[0008] Preferably, the dredging assembly includes a drill bit and a rotating rod, the rotating rod is movably installed inside the cavity, and one end of the rotating rod away from the shell penetrates the shell and is fixedly connected to the drill bit.

[0009] Preferably, a groove is provided on the drill bit, the groove is spiral-shaped, and a side of the drill bit close to the fixed tube is loosely matched with the fixed tube.

[0010] Preferably, a spiral blade is fixedly mounted on the rotating rod, a plurality of feed ports are opened on the fixed tube, the feed ports are evenly distributed on the circumference of the outer wall of the fixed tube, and the feed ports are located between the push plate and the drill bit.

[0011] Preferably, a limit plate is fixedly installed on the fixed pipe, the limit plate is arranged close to the shell, and the slag discharge port is located between the limit plate and the shell.

[0012] The beneficial effects of the utility model are as follows:

[0013] (1) The utility model uses a drill bit and a rotating rod in combination. First, the fixed pipe is inserted into the pipe to be dredged, and the control button is pressed to start the motor. The motor drives the rotating rod to rotate, and then drives the drill bit to rotate synchronously. When encountering a blockage with low hardness, the blockage is pushed around by the drill bit. When encountering a blockage with high hardness, the blockage is broken by rotating the drill bit and the groove, and moved around the fixed pipe along the groove. The cost is low and the dredging efficiency is high, so it is suitable for blockages of various hardness.

[0014] (2) The utility model uses a rotating rod and a spiral blade in coordination. After the drill bit pushes the blockage to the surroundings of the fixed pipe, the blockage enters the cavity from the feed port, is transported to the slag discharge port by the spiral blade, and is then discharged through the slag discharge port. The fixed pipe does not need to be pulled out of the pipeline during the entire slag discharge process, thereby achieving the discharge of the blockage during the dredging process.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] The present embodiment is used to solve the problem that the unblocking device in the prior art usually uses multiple high-pressure water streams to drive the nozzle into the pipe during use, and uses high-speed water flow to flush the inside of the pipe. The amount of water used during use is large, and when encountering harder blockages, the nozzle cannot rotate and is easily stuck by the blockage, resulting in low unblocking efficiency.

[0025] See also Figure 1 - Figure 3 As shown, this embodiment is a municipal engineering drainage pipe dredging device, including a shell 1, a motor 2 is fixedly installed inside the shell 1, a fixed block 3 is fixedly installed at the bottom of the shell 1, a control button 301 is fixedly installed on the fixed block 3, a fixed pipe 4 is fixedly installed at one end of the shell 1, a cavity 401 is arranged inside the fixed pipe 4, a dredging component 5 is movably installed in the fixed pipe 4, a slag discharge port 404 is opened at the bottom of the fixed pipe 4, the slag discharge port 404 is arranged close to the shell 1, and a push plate 402 is fixedly installed on the fixed pipe 4. In the process of placing the fixed pipe 4 in the pipeline, the edge of the push plate 402 is in contact with the inner wall of the pipeline. When the fixed pipe 4 moves into the pipeline, the push plate 402 pushes the silt on the inner wall of the pipeline, so that the silt accumulates at the feed port 505, and is transported to the slag discharge port 404 through the rotating rod 502 and the spiral blade 504 for discharge, thereby achieving thorough cleaning of the inside of the pipeline.

[0026] The dredging assembly 5 includes a drill bit 501 and a rotating rod 502. The rotating rod 502 is movably installed inside the cavity 401. The end of the rotating rod 502 away from the shell 1 passes through the shell 1 and is fixedly connected to the drill bit 501. A groove 503 is opened on the drill bit 501, and the groove 503 is spiral. The side of the drill bit 501 close to the fixed tube 4 is gap-matched with the fixed tube 4.

[0027] First, insert the fixed pipe 4 into the pipe that needs to be dredged, press the control button 301 to start the motor 2, and use the motor 2 to drive the rotating rod 502 to rotate, and then drive the drill bit 501 to rotate synchronously. When encountering a blockage with low hardness, the blockage is pushed around by the drill bit 501. When encountering a blockage with higher hardness, the rotating drill bit 501 and the groove 503 are used to break the blockage and move it around the fixed pipe 4 along the groove 503. The cost is low and the dredging efficiency is high, so it is suitable for blockages of various hardness.

[0028] Embodiment 2:

[0029] The method used in this embodiment to solve the problem of discharging the blockage is to recover the nozzle and use high-pressure water flow to remove the blockage. Therefore, the nozzle must be recovered periodically to discharge the blockage, which undoubtedly increases the workload and makes it difficult to discharge the blockage during the dredging process.

[0030] See also Figure 4 - Figure 5 As shown, the utility model also includes a spiral blade 504, which is fixedly mounted on the rotating rod 502, and a plurality of feed ports 505 are opened on the fixed tube 4, and the feed ports 505 are evenly distributed on the circumference of the outer wall of the fixed tube 4, and the feed ports 505 are located between the push plate 402 and the drill bit 501, and a limit plate 403 is fixedly mounted on the fixed tube 4, and the limit plate 403 is arranged close to the shell 1, and the slag discharge port 404 is located between the limit plate 403 and the shell 1.

[0031] After the drill bit 501 pushes the blockage around the fixed pipe 4, the blockage enters the cavity 401 from the feed port 505, is transported to the slag discharge port 404 by the spiral blade 504, and is discharged through the slag discharge port 404. The entire slag discharge process does not require the fixed pipe 4 to be pulled out of the pipeline, thereby achieving the discharge of the blockage during the dredging process.

[0032] In combination with Example 1 and Example 2, by using the drill bit 501 and the rotating rod 502 in coordination, the motor 2 is used to drive the drill bit 501 to rotate, and the drill bit 501 is used to push the blockage to the surroundings. When encountering a blockage with higher hardness, the rotating drill bit 501 and the groove 503 are used to break the blockage, so as to adapt to blockages of various hardnesses. The blockage enters the cavity 401 from the feed port 505, is transported to the slag discharge port 404 by the spiral blade 504, and is then discharged through the slag discharge port 404. The entire slag discharge process does not require the fixed pipe 4 to be pulled out of the pipeline, so that the blockage can be discharged during the dredging process.

[0033] The working process and principle of the utility model are as follows:

[0034] First, insert the fixed pipe 4 into the pipe to be dredged, press the control button 301 to start the motor 2, use the motor 2 to drive the rotating rod 502 to rotate, and then drive the drill bit 501 to rotate synchronously. When encountering a blockage with low hardness, the blockage is pushed around by the drill bit 501. When encountering a blockage with high hardness, the blockage is broken by rotating the drill bit 501 and the groove 503, and moves around the fixed pipe 4 along the groove 503. The cost is low and the dredging efficiency is high, so it is suitable for blockages of various hardnesses.

[0035] Furthermore, after the drill bit 501 pushes the obstruction around the fixed pipe 4, the obstruction enters the cavity 401 from the feed port 505, is transported to the slag discharge port 404 by the spiral blade 504, and is discharged through the slag discharge port 404. The fixed pipe 4 does not need to be pulled out from the pipeline during the entire slag discharge process, thereby achieving the discharge of the obstruction during the dredging process;

[0036] The utility model, through the dredging component 5, can adapt to blockages of various hardnesses and discharge the blockages during the dredging process.
