Description

Technical Field

[0001] The present application relates to the technical field of silt cleaning, and particularly relates to a maintenance device for the sludge pipeline of a dredger. Background Art

[0002] At present, the accumulation of silt in existing river channels and lakes is becoming increasingly serious, seriously affecting the ecological systems of river channels and lakes. In particular, these silts contain a large amount of pollutants, polluting the water source, and the silt accumulates higher and higher, raising the riverbed. With the increase in global abnormal weather, it is no longer a small probability event for large-scale basin floods to occur in rivers. Therefore, the cleaning of river silt has become a top priority, and most of the existing silt cleaning equipment is dredgers.

[0003] The silt ship sucks the silt at the bottom of the river into the sludge pipeline, so that the silt moves along the sludge pipeline to the shore, thereby achieving the purpose of silt cleaning. However, once the sludge pipeline is blocked, the silt cleaning work cannot be carried out, and the sludge pipeline needs to be dredged and repaired. Due to the material of the sludge pipeline, it may be bent, resulting in a more complex dredging and repair of the sludge pipeline. Summary of the Invention

[0004] In order to make the dredging and repair of the sludge pipeline more convenient, the present application provides a maintenance device for the sludge pipeline of a dredger.

[0005] The above technical object of the present application is achieved by the following technical solutions: A maintenance device for the sludge pipeline of a dredger includes a positioning ring and a connecting pipe. There are multiple positioning rings, and the multiple positioning rings are arranged inside the connecting pipe and are evenly distributed along the axial direction of the connecting pipe. The connecting pipe is connected with a driving structure for driving the connecting pipe to move forward. When in use, the connecting pipe is inserted into the sludge pipeline. A sludge conveying structure for driving the sludge to be discharged along the connecting pipe is arranged inside the connecting pipe. The connecting pipe is designed with a semi-rigid structure and has controllable bending deformation ability and resilience characteristics.

[0006] By adopting the above solution, when the sludge pipeline needs to be repaired and cleaned, the connecting pipe is inserted into the sludge pipeline, and the connecting rod is driven to move into the sludge pipeline through the driving structure. At the same time, the sludge conveying structure conveys the sludge in the sludge pipeline into the connecting pipe and discharges the sludge along the connecting pipe. And because the connecting pipe is designed with a semi-rigid structure, the connecting pipe can move more smoothly in the sludge pipeline, thereby making the repair and cleaning of the sludge pipeline more smooth.

[0007] Optionally, an isolation layer is arranged inside the connecting pipe. The sludge conveying structure is located between the isolation layer and the connecting pipe. The isolation layer is fixedly connected with the positioning ring, and the isolation layer is made of an elastic material.

[0008] By adopting the above solution, the mud conveying structure is separated from the silt, so as to prevent the silt from blocking the mud conveying structure and causing the mud conveying structure to fail to work normally.

[0009] Optionally, the driving structure includes a driving bracket, a driving wheel and a driving motor. A support ring is fixedly provided on the driving bracket. A plurality of driving wheels are provided. The plurality of driving wheels are rotatably connected to the support ring in a circular array, and the output shaft of the driving motor is connected to the axis of the driving wheel. The connecting pipe passes through the center of the support ring. The driving bracket is placed on the ground, and the driving motor drives the driving wheel to rotate, thereby driving the connecting pipe to move along the axis direction of the support ring.

[0010] By adopting the above solution, the driving motor drives the driving wheel to rotate, so that the driving wheel drives the connecting pipe to move into the mud conveying pipeline, thereby realizing the movement of the connecting pipe into the mud conveying pipeline.

[0011] Optionally, a circular scraper is provided at the outer edge of one end of the connecting pipe, and the scraper is made of semi-rigid material and can undergo elastic deformation.

[0012] By adopting the above solution, the amount of sludge entering the gap between the sludge conveying pipe and the connecting pipe is reduced, the sludge cleaning is more comprehensive, and the scraper made of semi-rigid material is not easy to scratch the sludge conveying pipe.

[0013] Optionally, the mud conveying structure includes a threaded rod, which is rotatably connected to a positioning ring, the positioning ring is fixedly connected to a mud conveying motor, the threaded rod is fixedly connected to an output shaft of the mud conveying motor, and a threaded sleeve is sleeved on the outer side of the threaded rod, which is connected to a vertical rod.

[0014] By adopting the above solution, the rotation of the mud conveying motor drives the threaded rod to rotate, thereby driving the threaded pipe and the vertical rod to move along the threaded rod. During the movement of the vertical rod, the vertical rod drives the sludge entering the connecting pipe to move toward the outlet, thereby achieving the mud conveying effect.

[0015] Optionally, an arc-shaped silt removal plate is fixedly connected to the side of the vertical rod facing away from the threaded sleeve.

[0016] By adopting the above solution, a silt removal plate is provided to increase the contact area with the silt, thereby driving more silt to move to the outlet and accelerating the efficiency of sludge transportation.

[0017] Optionally, the positioning ring is connected to a guide rod parallel to the threaded rod, the guide rod passes through the threaded sleeve, and the guide rod is slidably connected to the threaded sleeve.

[0018] By adopting the above solution, the threaded sleeve is prevented from rotating together with the threaded rod, so that the movement of the threaded sleeve is smoother.

[0019] Optionally, a rotating groove is formed in the threaded sleeve, and the vertical rod can rotate in the rotating groove, enabling the vertical rod to switch between a state perpendicular to the threaded rod and a state parallel to the threaded rod. A pin groove is formed at one end of the vertical rod located in the rotating groove. A pin spring and a latch are arranged in the pin groove. The latch is slidably connected in the pin groove, and a clamping groove is formed in the rotating groove. When the vertical rod is perpendicular to the threaded rod, a part of the latch is inserted into the clamping groove.

[0020] By adopting the above scheme, the sludge conveying motor drives the threaded rod to rotate, thereby driving the threaded sleeve and the vertical rod to move along the threaded rod, enabling the vertical rod to drive the sludge to move in the connecting pipe. The latch is stuck in the clamping groove, enabling the vertical rod to maintain a state perpendicular to the threaded rod, so that the vertical rod can drive the sludge to move in the connecting pipe more smoothly.

[0021] Optionally, the positioning ring is fixedly connected with an unlocking block and a state-changing block, and the unlocking block and the state-changing block are respectively located at both ends of the threaded rod. The unlocking block is fixedly connected with an unlocking rod, and the threaded sleeve is provided with an unlocking hole, and the unlocking hole is communicated with the clamping groove. One side of the latch inserted into the clamping groove is inclined. When the threaded sleeve approaches the unlocking block, the unlocking rod is inserted into the clamping groove and contacts the inclined surface of the latch to press the latch out of the unlocking groove. A torsion spring is connected to the rotating shaft of the vertical rod. When the torsion spring is in its original length, the vertical rod is parallel to the threaded rod. The state-changing block is connected with an inclined block. When the threaded sleeve approaches the state-changing block, the vertical rod contacts the inclined surface of the inclined block and drives the vertical rod to rotate from a state parallel to the threaded rod to a state perpendicular to the threaded rod.

[0022] By adopting the above scheme, when the vertical rod moves towards the side away from the inlet of the connecting pipe, the vertical rod is perpendicular to the threaded rod, enabling the vertical rod to drive the sludge to move towards the outlet direction in the connecting pipe. At this time, the torsion spring is in an energy storage state. Until the threaded sleeve reaches the position of the unlocking block, the unlocking rod is inserted into the unlocking hole, and the end of the unlocking rod is inserted into the clamping groove and presses the latch out of the clamping groove. The torsion spring rebounds, driving the vertical rod to rotate around the hinge axis, making the vertical rod parallel to the threaded rod. Subsequently, the vertical rod moves towards the inclined block, enabling the vertical rod to contact the inclined surface of the inclined block, and making the vertical rod rotate around the hinge axis until the vertical rod is perpendicular to the threaded rod and the latch is inserted into the clamping groove.

[0023] Optionally, each positioning ring is connected with a plurality of sludge conveying structures, and the plurality of sludge conveying structures are arranged in a circumferential array.

[0024] By adopting the above scheme, the sludge cleaning efficiency is higher and the cleaning effect is better.

[0025] In summary, the present application has the following technical effects: 1. By providing the connecting pipe and the sludge conveying structure, the sludge in the pipeline can be transported out along the connecting pipe; 2. By providing the isolation layer, the sludge conveying structure is prevented from being blocked by the mud; 3. By providing the sludge cleaning plate, the sludge can be cleaned more smoothly.

Detailed implementation manners

[0028] The following further elaborates on the present application in conjunction with the attached drawings.

[0029] Referring to Figure 1 , a mud conveying pipeline repair device for a dredger, comprising a positioning ring 1 and a connecting pipe 2. A plurality of positioning rings 1 are provided, and the plurality of positioning rings 1 are arranged inside the connecting pipe 2 and are evenly distributed along the axial direction of the connecting pipe 2. The connecting pipe 2 is connected with a driving structure 3 for driving the connecting pipe 2 to move forward. When in use, the connecting pipe 2 is inserted into the mud conveying pipeline. A mud conveying structure 4 for driving the mud to be discharged along the connecting pipe 2 is arranged inside the connecting pipe 2. The connecting pipe 2 is designed with a semi-rigid structure and has controllable bending deformation ability and resilience characteristics. When the mud conveying pipeline needs to be repaired and cleaned, the connecting pipe 2 is inserted into the mud conveying pipe, and the driving structure 3 drives the connecting rod to move into the mud conveying pipe. At the same time, the mud conveying structure 4 conveys the mud in the mud conveying pipe into the connecting pipe 2 and discharges the mud along the connecting pipe 2. And because the connecting pipe 2 is designed with a semi-rigid structure, the connecting pipe 2 can move more smoothly in the mud conveying pipe, thereby making the repair and cleaning of the mud conveying pipeline smoother.

[0030] Referring to Figure 1An isolation layer 5 is provided in the connecting pipe 2, the mud transport structure 4 is located directly between the isolation layer 5 and the connecting pipe 2, and the isolation layer 5 is fixedly connected to the positioning ring 1, and the isolation layer 5 is made of elastic material. The isolation layer 5 separates the mud transport structure 4 from the silt, preventing the silt from blocking the mud transport structure 4 and causing the mud transport structure 4 to fail to work normally.

[0031] Reference Figure 2 The driving structure 3 includes a driving bracket 31, a driving wheel 32 and a driving motor 33. A supporting ring 311 is fixedly arranged on the driving bracket 31. A plurality of driving wheels 32 are arranged. The plurality of driving wheels 32 are rotatably connected to the supporting ring 311 in a circular array, and the output shaft of the driving motor 33 is connected to the axis of the driving wheel 32. The connecting pipe 2 passes through the center of the supporting ring 311. The driving bracket 31 is placed on the ground. The driving motor 33 drives the driving wheel 32 to rotate, thereby driving the connecting pipe 2 to move along the axis direction of the supporting ring 311. The driving motor 33 drives the driving wheel 32 to rotate, so that the driving wheel 32 drives the connecting pipe 2 to move into the mud conveying pipeline, thereby realizing the movement of the connecting pipe 2 into the mud conveying pipeline. A circular scraper 6 is arranged at the outer edge of one end of the connecting pipe 2. The scraper 6 is made of semi-rigid material and can be elastically deformed. The amount of sludge entering the gap between the mud conveying pipe and the connecting pipe 2 is reduced, so that the sludge cleaning is more comprehensive. The scraper 6 made of semi-rigid material is not easy to scratch the mud conveying pipe.

[0032] Reference Figure 3 and Figure 4 , each positioning ring 1 is connected to a plurality of mud conveying structures 4, and the plurality of mud conveying structures 4 are arranged in a circular array. The mud conveying structure 4 includes a threaded rod 41, the threaded rod 41 is rotatably connected to the positioning ring 1, the positioning ring 1 is fixedly connected to a mud conveying motor 43, the threaded rod 41 is fixedly connected to the output shaft of the mud conveying motor 43, and a threaded sleeve 42 is sleeved on the outer side of the threaded rod 41, and the threaded sleeve 42 is connected to a vertical rod 7. A circular arc-shaped dredging plate 71 is fixedly connected to the side of the vertical rod 7 away from the threaded sleeve 42. The positioning ring 1 is connected to a guide rod 8 parallel to the threaded rod 41, the guide rod 8 passes through the threaded sleeve 42, and the guide rod 8 is slidably connected to the threaded sleeve 42. The rotation of the mud conveying motor 43 drives the threaded rod 41 to rotate, thereby driving the threaded pipe and the vertical rod 7 to move along the threaded rod 41. During the movement of the vertical rod 7, the vertical rod 7 drives the silt entering the connecting pipe 2 to move toward the outlet, thereby achieving the mud conveying effect.

[0033] Reference Figure 4 , Figure 5 ,and Figure 6The threaded sleeve 42 is provided with a rotation groove 421, and the vertical rod 7 can rotate in the rotation groove 421, so that the vertical rod 7 can switch between the state of being perpendicular to the threaded rod 41 and being parallel to the threaded rod 41. A pin groove 72 is provided at one end of the vertical rod 7 located in the rotation groove 421, and a pin spring 74 and a bayonet 73 are provided in the pin groove 72. The bayonet 73 is slidably connected in the pin groove 72, and a bayonet groove 422 is provided in the rotation groove 421. When the vertical rod 7 is perpendicular to the threaded rod 41, the bayonet pin 73 is partially inserted into the bayonet groove 422. The positioning ring 1 is fixedly connected with an unlocking block 91 and a state-changing block 9, and the unlocking block 91 and the state-changing block 9 are respectively located at the two ends of the threaded rod 41, the unlocking block 91 is fixedly connected with an unlocking rod 92, and the threaded sleeve 42 is provided with an unlocking hole 423, and the unlocking hole 423 is communicated with the card slot 422, and the bayonet 73 is inserted into the card slot 422 at one side in an inclined state. When the threaded sleeve 42 approaches the unlocking block 91, the unlocking rod 92 is inserted into the card slot 422 and contacts the inclined surface of the bayonet 73 to press the bayonet 73 out of the unlocking groove, and the rotating shaft of the vertical rod 7 is connected with a torsion spring 75. When the torsion spring 75 is at its original length, the vertical rod 7 is parallel to the threaded rod 41, and the state-changing block 9 is connected with an inclined block 93. When the threaded sleeve 42 approaches the state-changing block 9, the vertical rod 7 contacts the inclined surface of the inclined block 93, and drives the vertical rod 7 from a state parallel to the threaded rod 41 to a state perpendicular to the threaded rod 41. When the vertical rod 7 moves away from the inlet side of the connecting pipe 2, the vertical rod 7 is perpendicular to the threaded rod 41, so that the vertical rod 7 drives the silt to move in the connecting pipe 2 toward the outlet direction. At this time, the torsion spring 75 is in an energy storage state. Until the threaded sleeve 42 reaches the position of the unlocking block 91, the unlocking rod 92 is inserted into the unlocking hole 423, and the end of the unlocking rod 92 is inserted into the inside of the slot 422, and the bayonet 73 is pressed out of the slot 422, and the torsion spring 75 rebounds, driving the vertical rod 7 to rotate around the hinge axis, so that the vertical rod 7 is parallel to the threaded rod 41, and then the vertical rod 7 moves close to the inclined block 93, so that the vertical rod 7 contacts the inclined surface of the inclined block 93, and the vertical rod 7 rotates around the hinge axis until the vertical rod 7 is perpendicular to the threaded rod 41 and the bayonet 73 is inserted into the slot 422.

[0034] The specific implementation principle of this application is as follows: When it is necessary to repair and clean the sludge conveying pipeline, the connecting pipe 2 is inserted into the pipeline interior. Subsequently, the driving motor 33 rotates to drive the driving wheel 32 to rotate, thereby driving the connecting pipe 2 to move into the sludge conveying pipe. At the same time, the sludge cleaning motor 43 rotates to drive the threaded rod 41 to rotate, thereby driving the threaded sleeve 42 and the vertical rod 7 to move away from the inlet direction of the connecting pipe 2, thus driving the sludge to move. When the threaded sleeve 42 moves to the position of the unlocking block 91, the unlocking rod 92 is inserted into the unlocking hole 423, thereby ejecting the latch 73 out of the card slot 422. At this time, the torsion spring 75 rebounds, driving the vertical rod 7 to rotate around the hinge axis, making the vertical rod 7 parallel to the threaded rod 41. Subsequently, the sludge cleaning motor rotates in reverse, causing the threaded sleeve 42 and the vertical rod 7 to move closer to the switching block 9. The vertical rod 7 contacts the inclined surface of the inclined block 93, causing the vertical rod 7 to move along the inclined surface and rotate around the hinge axis until the vertical rod 7 is perpendicular to the threaded rod 41. At this time, the pin spring 74 rebounds, causing the latch 73 to be inserted into the card slot 422. Subsequently, the sludge cleaning motor rotates in reverse again, driving the vertical rod 7 to move away from the inlet direction of the connecting pipe 2, and so on, thereby realizing the removal of the sludge.
