Description

Technical Field

[0001] The present invention relates to the technical field of river channel regulation, in particular to a river channel regulation and silt removal device. Background Art

[0002] River silt blockage is a complex urban environmental problem, caused by the interaction of natural and human factors. Sediment removal in river management is a key step in restoring river functions and improving the water environment. Targeted measures must be taken based on the causes of siltation.

[0003] In actual practice, it was found that high-velocity water would wash away surface sediments on the riverside walls. When the water flow slowed down, these sediments would re-aggregate and settle in the depressions of the riverside walls. When the vegetation on the riverbank was lush, suspended matter was more likely to adhere to the vegetated sidewalls, forming a thin layer of silt. On the contrary, areas lacking vegetation may be more susceptible to erosion, and the sidewalls would not have much silt.

[0004] Therefore, in the process of river management, it is also very important to clean up the silt accumulated on the side walls of the river. This is because the accumulation of silt on the side walls will reduce the water flow section of the river and reduce the flood discharge capacity of the river. During heavy rain or floods, the river with silt accumulation is prone to flood disasters, causing huge losses to agriculture, industry and residents in the surrounding areas.

[0005] The existing method of clearing river silt is mostly to divide the river into sections and build cofferdams, use water pumps to drain the accumulated water within the cofferdam range, and then use long-arm excavators to clear the silt. This method clears the silt thoroughly and is easy to control the silt clearing depth. However, due to the limitations of the excavator's digging claws, after the protruding silt on both sides is cleared, the silt in the sunken positions cannot be further cleared. Summary of the Invention

[0006] The purpose of the present invention is to propose a river channel management and silt removal device to solve the problem that when using a long-arm excavator for silt removal, the silt in the recessed position cannot be further cleaned after the protruding silt on both sides is cleared due to the limitations of the excavator's digging claws.

[0060] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical river channel management and silt removal device in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0061] In order to solve the problem that the silt in the recessed position cannot be further cleaned after the protruding silt on both sides is cleaned due to the limitation of the excavator's digging claws when using a long-arm excavator for silt removal, the present invention proposes a river channel management and silt removal device, such as Figure 1 - Figure 14 As shown:

[0062] The cleaning device 10 includes a pump 11, two mud discharge channels 12 connected to the pump 11, and a sliding base 13 installed at the bottom of the pump 11. The pump 11 sucks the silt entering the sliding base 13 through the mud discharge channel 12 at the bottom and pumps it out through the mud discharge channel 12 at the top. A cutting mechanism 20 is installed on both sides of the sliding base 13. The cutting mechanism 20 includes a mounting cavity 21 rotatably mounted on the sliding base 13 and a rotatable cutting reamer 22 mounted on the mounting cavity 21.

[0063] The sliding base 13 includes a top plate 133 mounted on the bottom of the pump 11, mounting plates 132 disposed on both sides of the top plate 133, and an inclined shovel plate 131 disposed at the bottom of the mounting plate 132. The inclined shovel plate 131 can better shovel the cut silt.

[0064] The mounting cavity 21 is rotatably mounted on the top plate 133 and extends into the mounting plate 132. The cutting reamer 22 extends through the mounting plate 132 and outward. The middle of the top plate 133 is penetrated by the mud discharge channel 12, and the mud discharge channel 12 extends to the middle of the shovel plate 131.

[0065] Before using the cleaning equipment 10 for dredging, it is necessary to first divide the river channel into sections and build a cofferdam, use a water pump to drain the accumulated water within the cofferdam range, and then use a long-arm excavator to clear the silt in the protruding positions on both sides of the river bank. After the cleaning is completed, the cleaning equipment 10 is used to clean the silt in the recessed positions. In order to facilitate the pushing of the cleaning equipment 10 and the rotation of the mounting cavity 21, a handle 27 that is easy to hold is installed on the mounting cavity 21. By pushing the handle 27, the handle 27 drives the shovel plate 131 to slide on the river channel. During the sliding process, the rotating cutting auger 22 is close to the edge of the river channel. At this time, the cutting auger 22 rotates to cut the silt on the river channel wall. The cut silt is shoveled up by the moving shovel plate 131 and reaches the mud discharge channel 12 set at the bottom of the pump 11. The silt is pumped to the mud discharge channel 12 set at the top through the pump 11. The mud discharge channel 12 at the top can be connected to the mud suction pipe to transport the silt to the yard.

[0066] In order to be able to drive the cutting reamer 22 to rotate, as Figure 5 and Figure 6 As shown, the cutting mechanism 20 further includes a driving wheel 24 and a transmission belt 26 rotatably disposed inside the mounting cavity 21 , and a driven wheel 25 is provided on the surfaces of the driving wheel 24 and the transmission belt 26 that engage with each other;

[0067] A power source is mounted on the mounting cavity 21. A motor mounting platform 211 for placing the power source is mounted on the outer wall of the mounting cavity 21. A power source motor 23 is mounted on the motor mounting platform 211. The output end of the power source is connected to the driving wheel 24. The cutting reamer 22 is connected to the transmission belt 26. When the motor 23 is started, the torque generated by the motor 23 is transmitted to the transmission belt 26 through the driving wheel 24 and the driven wheel 25 to drive the cutting reamer 22 to rotate.

[0068] At the same time, in order to ensure the stability of the rotation of the driving wheel 24 and the transmission belt 26, a mounting platform 241 is provided on the inner wall of the mounting cavity 21 at the same axial position as the driving wheel 24 and the transmission belt 26. A plurality of mounting brackets 242 are mounted on the mounting platform 241. Grooves that engage with the mounting brackets 242 are provided on both sides of the driving wheel 24 and the transmission belt 26.

[0069] This design allows the driving wheel 24 and the transmission belt 26 to rotate within the constraints of the mounting bracket 242 , preventing them from deflecting during rotation, while increasing the stability of the cutting reamer 22 connected to the transmission belt 26 during rotation.

[0070] In order to cut the silt in the concave position, the cutting reamer 22 needs to be tilted toward the side of the river channel wall to come into contact with the silt. To achieve this purpose, it is necessary to hold and push the handle 27 so that the handle 27 drives the mounting chamber 21 to rotate under the restriction of the top plate 133. The cutting reamer 22 deviates with the rotation of the mounting chamber 21, thereby achieving the purpose of cleaning the silt in the concave positions on both sides of the river channel.

[0071] At the same time, in order to ensure that the mud under the tilt can enter the shovel plate 131, Figure 3 、 Figure 4 and Figure 11 As shown, a guide plate mounting platform 212 is integrally formed on the motor mounting platform 211, and a mounting rod 52 is mounted on the end of the guide plate mounting platform 212. A guide plate 53 is mounted on the mounting rod 52, and the guide plate 53 is arranged at an angle on the inner side of the cutting reamer 22. Under the guidance of the guide plate 53, the silt cut by the cutting reamer 22 can move toward the middle of the shovel plate 131 under the guidance of the guide plate 53. As the shovel plate 131 moves, the silt is scooped up by the shovel plate 131 and reaches the mud discharge channel 12.

[0072] A guide groove 51 is provided on the surface of the top plate 133 for the installation rod 52 to pass through. Through this design, when the installation cavity 21 rotates, the installation rod 52 moves in the guide groove 51 to drive the guide plate 53 and the cutting reamer 22 to adjust synchronously, so as to ensure that the angle between the guide plate 53 and the cutting reamer 22 does not change with the deviation of the cutting reamer 22, thereby achieving the purpose of ensuring that the silt can be normally gathered under the guidance of the shovel plate 131 and the guide plate 53.

[0073] Furthermore, the mounting cavity 21 is locked by the locking mechanism 30 after being rotated, such as Figure 3 、 Figure 5 、 Figure 9 and Figure 10 As shown, the locking mechanism 30 includes a connector 31 connected to the bottom of the installation cavity 21 and a lifting rod 34 slidably mounted on the surface of the connector 31. The connector 31 is provided with a snap ring 32. The lifting rod 34 is provided with a limit ring 36 that engages with the snap ring 32. When the lifting rod 34 slides to separate the snap ring 32 from the limit ring 36, the installation cavity 21 is rotated to adjust the distance between the cutting reamer 22 and the river wall.

[0074] The locking mechanism 30 further includes a mounting slot 33 provided in the mounting plate 132 , a lifting rod 34 slidably embedded in a first spring 35 and a first spring 35 is provided at the bottom of the lifting rod 34 ;

[0075] An annular chamber is provided on the surface of the connecting member 31. When it is necessary to release the restriction of the mounting cavity 21 so that it can rotate to adjust the angle of the cutting reamer 22, the lifting rod 34 is pushed to make the lifting rod 34 slide under the restriction of the mounting groove 33. During the sliding process, the lifting rod 34 pulls the first spring 35 to cause it to elastically deform. At the same time, the lifting rod 34 drives the limiting ring 36 to move on the surface of the clamping ring 32, so that the limiting ring 36 separates from the clamping ring 32 and reaches the annular chamber of the connecting member 31. At this time, the mounting cavity 21 drives the connecting member 31 and the clamping ring 32 to rotate without being restricted by the limiting ring 36. The mounting cavity 21 drives the connecting member 31 to rotate in the lifting rod 34, thereby achieving the purpose of rotating the cutting reamer 22.

[0076] After the position adjustment of the cutting reamer 22 is completed, the lifting rod 34 is reset under the pull of the elastic deformation recovery of the first spring 35, and the limiting ring 36 is re-engaged with the clamping ring 32. Under the restriction of the clamping ring 32 and the limiting ring 36, the installation cavity 21 cannot drive the connecting member 31 to rotate, thereby preventing the cutting reamer 22 from deflecting during the cutting process.

[0077] In order to enable the staff to adjust the position of the lifting rod 34 by other actions while holding the handle 27 with both hands, such as Figure 8 and Figure 9 As shown, the lifting rod 34 is driven to slide by an unlocking mechanism 40. The unlocking mechanism 40 includes a hinge 41 mounted on the mounting plate 132 and connecting shafts 45 mounted on both sides of the lifting rod 34. A hinge shaft 42 is rotatably provided on the hinge 41, and a telescopic link 43 and a fixed link 44 are respectively connected to the two sides of the hinge shaft 42. The connecting shaft 45 is connected to the telescopic link 43, and a pedal 46 is connected to the end of the fixed link 44.

[0078] When it is necessary to release the restriction on the installation cavity 21 so that it can rotate, the staff can step on the pedal 46, so that the pedal 46 drives the hinge shaft 42 to rotate under the restriction of the hinge 41 through the fixed connecting rod 44. A torsion spring (not shown in the figure) can be set in the hinge 41. The elastic deformation of the torsion spring resets the hinge shaft 42 to reverse, thereby resetting the pedal 46. As the hinge shaft 42 rotates, the telescopic connecting rod 43 rotates with the hinge 41 as the axis and pulls the connecting shaft 45. The connecting shaft 45 drives the lifting rod 34 to rise. Since the lifting rod 34 is nested in the installation groove 33, the telescopic connecting rod 43 will shrink during the rotation to adapt to the change in the distance between the connecting shaft 45 and the hinge shaft 42. The position adjustment of the lifting rod 34 is completed, and the installation cavity 21 can be rotated.

[0079] In order to ensure that the silt can be pumped out smoothly through the pump 11 and the mud outlet channel 12, the top plate 133 is separated into an inlet and an outlet by the mounting plate 132. The top of the connection between the inlet and the outlet is penetrated by the mud outlet channel 12 and the bottom is provided with an opening and closing mechanism 60, such as Figure 12and Figure 13 As shown, the opening and closing mechanism 60 includes a rotating seat 61 rotatably arranged at the connection, and an arc-shaped baffle 62 is installed on the rotating seat 61 to block the connection, and a notch is provided on the surface of the baffle 62 for silt to pass through;

[0080] By rotating the baffle 62, the baffle 62 is rotated under the restriction of the rotating seat 61 to cooperate with the mounting plates 132 on both sides to block the connection. At this time, the sludge entering the shovel plate 131 cannot pass through the connection to reach the outlet. The sludge can be temporarily accumulated at the connection and wait for being sucked into the mud outlet channel 12.

[0081] At the same time, during the dredging operation, sometimes it is not necessary to clear the silt from the river channel, but to gather it at the shallower position of the silt at the bottom of the river channel for filling. Therefore, it is possible to choose not to start the pump 11 and the mud outlet channel 12, and then rotate the baffle 62 to release the blockage of the connection. The silt can pass through the gap on the surface of the baffle 62 to reach the outlet, and the silt passes through the outlet and remains in the river channel.

[0082] Furthermore, in order to fix the position of the baffle 62, as shown in FIG. Figure 14 As shown, two positioning holes 63 are provided on the surface of the baffle 62, and a positioning member 64 is provided on the mounting plate 132 to fix the position of the baffle 62 through the positioning holes 63;

[0083] The positioning member 64 includes a receiving cavity 641 provided on the mounting plate 132 and a latch 642 slidably disposed in the receiving cavity 641 and capable of being inserted into the positioning hole 63. When the latch 642 is inserted into the positioning hole 63 at different positions, the baffle 62 is respectively in an open and closed state at the connection. A second spring 643 is provided between the receiving cavity 641 and the latch 642.

[0084] A straight groove is formed on the surface of the accommodating cavity 641, and a handle 644 is provided on the latch 642 and passes through the straight groove;

[0085] By pulling the handle 644, the handle 644 drives the pin 642 to slide in the accommodating cavity 641 and squeeze the second spring 643, and the pin 642 moves out of the positioning hole 63 to release the restriction on the position of the baffle 62. After the baffle 62 is rotated and adjusted, the pin 642 can be inserted into another positioning hole 63 to further restrict the baffle 62.

[0086] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field of the present invention can make equivalent replacements or changes to the river channel management and silt removal device and its inventive concept within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
