Description

Technical Field

[0001] This application relates to the field of river dredging, and in particular to a river dredging device and dredging method. Background Technology

[0002] River dredging methods typically include dry dredging and wet dredging. Wet dredging usually involves using dredging vessels and other equipment to remove silt from the bottom of the river without the need for cofferdams. However, dry dredging is necessary for small rivers where dredging vessels cannot access them.

[0003] Currently, before dredging small rivers, it is usually necessary to set up cofferdams to cut off the water flow in the river, exposing the silt at the bottom of the river. Then, excavators and other equipment are used to clean up the exposed silt at the bottom of the river.

[0004] However, this method requires the construction of cofferdams, which takes time to set up cofferdams in the river channel during the entire dredging process. After the dredging is completed, the cofferdams need to be dismantled to restore the flow of water in the river channel. This makes the dredging process take a long time, thus reducing the efficiency of dredging. Summary of the Invention

[0005] In order to improve the efficiency of river dredging, firstly, this application provides a river dredging device.

[0006] The river dredging equipment provided in this application adopts the following technical solution:

[0007] The system includes a walking mechanism, a robotic arm, a connecting base, a dredging component, and an interception component. One end of the robotic arm is connected to the walking mechanism, and the other end is connected to the connecting base. The dredging component includes a fixed arc cover, a dredging arc cover, and a drive motor. The fixed arc cover is mounted on the connecting base, and the dredging arc cover is mounted on the fixed arc cover. The drive motor is mounted on the connecting base to drive the dredging arc cover to rotate around its own axis on the fixed arc cover. A holding space for holding silt in the river channel can be formed between the dredging arc cover and the fixed arc cover. Two sets of interception components are provided and located at both ends of the fixed arc cover. The interception components are detachably mounted on the connecting base and are used to intercept the water flow in the river channel.

[0008] By adopting the above technical solution, when dredging a small river channel is required, the traveling mechanism is first activated, causing the connecting base to move to the riverbank via a robotic arm. Then, the robotic arm is driven to position the connecting base above the river channel and lower it towards the channel. This allows the interception components to cut off the water flow. Once the water flow is cut off, the connection between the connecting base and the interception components is broken, allowing the connecting base to move freely between the two sets of interception components. Finally, the drive motor is activated to move the dredging arc cover. The dredging arc cover rotates around its own axis inside the fixed arc cover, allowing it to clean the silt at the bottom of the river when it rotates out of the fixed arc cover. When the dredging arc cover rotates back, the robotic arm can be driven to move the connecting base from above the river to the side, and the dredging arc cover can be driven by the drive motor to rotate around its own axis to empty the silt inside the dredging arc cover. This process is repeated until the silt between the two sets of interception components is cleared. During the entire dredging process, there is no need to spend extra time building and dismantling cofferdams, thus improving the efficiency of river dredging.

[0009] Optionally, the dredging arc cover is provided with multiple water filter tanks, which are distributed at intervals along the length of the dredging arc cover.

[0010] By adopting the above technical solution, the water filter tank allows the water carried in the sludge inside the dredging arc cover to flow out through the water filter tank, reducing the weight of the sludge inside the dredging arc cover, and also reducing the weight of the dredging arc cover itself, thus reducing the load on the robotic arm.

[0011] Optionally, the connecting base includes a connecting seat and two mounting seats. The connecting seat is connected to the robotic arm. A fixed arc cover is fixedly mounted on the connecting seat. The two mounting seats are located at both ends of the connecting seat. Two sets of interception components are respectively mounted on the two mounting seats. The mounting seats and the connecting seat are connected in a detachable manner.

[0012] By adopting the above technical solution, the connecting base includes a connecting seat and two mounting seats. The two mounting seats are located at both ends of the connecting seat and are detachably connected to the connecting seat. This allows the connecting seat to be detached from the two mounting seats, thereby enabling the dredging arc cover to repeatedly clean the silt in the river channel between the two mounting seats without moving the mounting seats. At the same time, it also further reduces the load on the robotic arm during the dredging process, thus extending the service life of the robotic arm.

[0013] Optionally, the interception assembly includes an interception plate and a driving component. The mounting base is provided with a sliding groove, the sliding groove extending perpendicular to the length direction of the fixed arc cover. The interception plate is provided with a sliding part located in the sliding groove and capable of sliding within the sliding groove. The driving component is mounted on the mounting base to drive the interception plate to slide along the extension direction of the sliding groove.

[0014] By adopting the above technical solution, the sliding fit between the sliding groove and the sliding part guides the sliding direction of the intercepting plate, while the driving component drives the intercepting plate to slide along the length of the sliding groove. By driving the two intercepting plates separately with two driving components, the actions of the two driving plates can be sequential. This ensures that, under the premise of water flow in the river channel, the two intercepting plates will not be inserted into the river channel at the same time to cut off the water flow, and the water between the two intercepting plates will not need to be drained afterward, thus saving construction costs.

[0015] Optionally, the interceptor plate has a cavity, and the cavity contains a ground insertion component and two movable plates. The two movable plates are located on both sides of the ground insertion component. The ground insertion component includes a fixedly connected ground insertion part and a transmission part. The ground insertion part is located outside the cavity for insertion into the bottom of the river channel, and the transmission part is located inside the cavity. Racks are provided on both sides of the transmission part. A hinge rod is provided on each movable plate. The hinge rod is fixedly installed in the cavity. The two movable plates are provided with transmission teeth that can mesh with the racks.

[0016] By adopting the above technical solution, when the intercepting plate is inserted into the river channel, the insertion part of the insertion component abuts against the bottom of the river channel, thereby causing the transmission part on the insertion component to rise relative to the intercepting plate in the cavity. Since each movable plate is provided with transmission teeth that can mesh with the rack on the transmission part, this causes the two movable plates to rotate around the axis of the hinge rod, and then rotate out from the intercepting plate and press against both sides of the river channel, which increases the stability of the intercepting plate when cutting off the water flow in the river channel. At the same time, when the insertion plate is lifted out of the river channel, the insertion component descends relative to the insertion plate under its own weight. At this time, under the action of the transmission teeth and the rack, the movable plate rotates back, which reduces the space occupied by the intercepting plate.

[0017] Optionally, a limit block is provided on the ground insertion part, which can abut against the interceptor plate.

[0018] By adopting the above technical solution, a limiting block is set on the insertion part, which allows the insertion part to enter the cavity of the interception plate when it is inserted with the bottom of the river channel, so that the meshing between the rack and the transmission gear will not easily fail.

[0019] Optionally, an anti-detachment block is provided at the end of the transmission unit away from the insertion part. The anti-detachment block is used to prevent the transmission unit from coming out of the cavity.

[0020] By adopting the above technical solution, an anti-detachment block is provided at the end of the transmission part away from the ground insertion part, so that the ground insertion part will not come out of the interceptor plate, reducing the possibility of the ground insertion part falling off the interceptor plate.

[0021] Secondly, this application provides a river dredging method, which employs the aforementioned river dredging equipment and includes the following steps:

[0022] S100: Move the walking mechanism to the location on the river where silt needs to be cleared;

[0023] S200: The robotic arm moves the connecting base above the river channel and drives the connecting base to move towards the river channel;

[0024] S300: The water flow in the river is intercepted by the interception component, thus cutting off the water flow between the two sets of dredging components;

[0025] S400: Uses a dredging arc cover to clean the silt in the section of the river where the water flow is blocked.

[0026] In summary, this application includes at least the following beneficial technical effects:

[0027] 1. By setting a connecting base on the robotic arm, and installing dredging and interception components on the connecting base, the interception components can cut off the water flow in the river during dredging operations in small waterways, thus acting as a cofferdam. After the dredging is completed, the interception components can be removed from the river by removing the connecting base from the river. The entire process does not require the construction and dismantling of cofferdams, saving time and improving the efficiency of dredging operations.

[0028] 2. By setting the connecting base as a connecting seat and two mounting seats, and the connection between the two mounting seats and the connecting seat is detachable, the connecting seat can be detached from the two mounting seats and move together with the robotic arm after the interception component is inserted into the river channel to cut off the water flow in the river channel. This allows the dredging arc cover to clean the river channel between the two mounting seats repeatedly, thereby improving the cleaning quality. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] Example 1

[0037] Embodiment 1 of this application discloses a river dredging device, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a walking mechanism 1, a robotic arm 2, a connecting base 3, a dredging component 4, and an interception component 5. The walking mechanism 1 uses tracks for movement. One end of the robotic arm 2 is mounted on the walking mechanism 1, and the other end of the robotic arm 2 is connected to the connecting base 3. The connecting base 3 includes a connecting seat 9 and two mounting seats 10. The two mounting seats 10 are respectively installed at both ends of the length direction of the connecting seat 9. Both mounting seats 10 are connected to the connecting seat 9 by bolts, which allows the connecting seat 9 to detach from the two mounting seats 10 while the two mounting seats 10 are fixed. The dredging component 4 is installed on the lower surface of the connecting seat 9, and there are two sets of interception components 5, which are respectively installed on the mounting seats 10.

[0038] In other embodiments, electromagnets can be provided at both ends of the connecting seat 9 along its length, so that the mounting seat 10 can be magnetically attached to the connecting seat 9, thereby achieving a detachable connection between the mounting seat 10 and the connecting seat 9.

[0039] Reference Figure 3 and Figure 4The dredging component 4 includes a fixed arc cover 6 and a dredging arc cover 7. Both the fixed arc cover 6 and the dredging arc cover 7 are semi-circular covers. The fixed arc cover 6 is fixedly installed on the lower surface of the connecting seat 9 with the opening facing downwards, while the dredging arc cover 7 is coaxially installed inside the fixed arc cover 6. When the dredging arc cover 7 is in its initial position, the opening of the dredging arc cover 7 overlaps with the opening of the fixed arc cover 6. A drive motor with a braking function is fixedly installed at the bottom of the connecting base 9. The output shaft of the drive motor is connected to the dredging arc cover 7. The drive motor is used to drive the dredging arc cover 7 to rotate around its own axis inside the fixed arc cover 6. This allows the dredging arc cover 7 to clean the silt accumulated at the bottom of the river channel by rotating around its own axis. At the same time, as the dredging arc cover 7 rotates, the opening of the dredging arc cover 7 will rotate to a position opposite to the opening of the fixed arc cover 6. At this time, the drive motor stops rotating. This allows the dredging arc cover 7 to form a silt-holding space between the fixed arc cover 6 and the dredging arc cover 7. The fixed arc cover 6 ensures that the silt inside the dredging arc cover 7 will not easily spill out during the process of the robotic arm 2 moving the connecting base 3.

[0040] Furthermore, multiple water filter channels 8 are provided on the dredging arc cover 7. The water filter channels 8 are distributed at intervals along the length of the dredging arc cover 7. This allows the water in the sludge to flow out through the water filter channels 8 when there is sludge in the dredging arc cover 7. This reduces the weight of the dredging arc cover when it is filled with sludge, thereby reducing the load borne by the robotic arm 2.

[0041] Reference Figure 2 and Figure 5 The interception component 5 includes an interception plate 11 and a drive component 12. The drive component 12 is a motor with a braking function. A sliding groove 13 is provided on the mounting base 10. The sliding groove 13 is a C-shaped groove. The extension direction of the sliding groove 13 is perpendicular to the length direction of the fixed arc cover 6. A sliding part 14 adapted to the sliding groove 13 is provided on the interception plate 11. A connecting transmission rack is provided on the side of the sliding part 14 away from the interception plate 11. The length direction of the transmission rack is consistent with the length direction of the interception plate 11. An active gear that can mesh with the transmission rack is installed on the output shaft of the drive component 12. This allows the position of the interception plate 11 on the mounting base 10 to be adjusted by the drive component 12 driving the active gear to rotate, thereby realizing the height adjustment of the interception plate 11 on the mounting base 10.

[0042] A cavity 15 is provided inside the interceptor plate 11. A grounding component 16 and two movable plates 17 are disposed within the cavity 15. The two movable plates 17 are located on either side of the grounding component 16. The grounding component 16 includes a fixedly connected grounding part 18 and a transmission part 19. The grounding part 18 is located outside the cavity 15 and below the grounding plate, while the transmission part 19 is located inside the cavity 15 and can slide up and down within it. Racks 20 are provided on both sides of the transmission part 19, with the length direction of the racks 20 aligned with the length direction of the transmission part 19. The two movable plates 17 are fan-shaped, and each movable plate 17 is provided with a hinge rod 21. The hinge rod 21 can rotate relative to the movable plate 17 around its own axis. The hinge rod 21 is fixedly connected in the cavity 15. The axis of the hinge rod 21 is perpendicular to the intercepting plate 11. This allows the movable plate 17 to rotate out of or back into the cavity 15 of the intercepting plate 11 by rotating around the axis of the hinge rod 21. At the position where the movable plate 17 connects to the hinge rod 21, there is also a transmission tooth 22 that can mesh with the rack 20 on the transmission part 19.

[0043] This allows the two movable plates 17 to rotate out from both sides of the interceptor plate 11 or rotate back into the interceptor plate 11 simultaneously due to the meshing between the transmission teeth 22 and the rack 20 when the transmission part 19 slides up and down in the cavity 15 of the interceptor plate 11. This makes it possible for the transmission part 19 to move relative to the interceptor plate 11 out of the river after the ground insertion part 18 is inserted into the ground when the interceptor plate 11 is placed in the river. During the movement of the transmission part 19 out of the river, the two movable plates 17 will rotate out from the side of the interceptor plate 11 and press against the river slope, further increasing the stability of the interceptor plate 11 in the river. This ensures that when the connection between the mounting plate and the connecting plate is lost, the interceptor plate 11 will not easily shift position or overturn in the river due to the impact of the water flow when it cuts off the water flow.

[0044] Furthermore, a limiting block 23 is provided at the position of the insertion part 18 near the transmission part 19. The limiting block 23 can abut against the lower end face of the intercepting plate 11. This allows the intercepting plate 11 to be pressed down further by activating the driving component 12 when the insertion depth of the insertion part 18 at the bottom of the river is insufficient. The pressure is then transmitted to the insertion part 18 through the limiting block 23, allowing the insertion part 18 to be inserted further into the bottom of the river. At the same time, the limiting block 23 also prevents the insertion part 18 from entering the cavity 15 from outside the intercepting plate 11. This prevents the connection between the transmission teeth 22 20 and the transmission teeth 22 from easily failing.

[0045] Furthermore, an anti-detachment block 24 is fixedly connected to the end of the transmission part 19 away from the ground insertion part 18. The anti-detachment block 24, like the ground insertion part 18, is located outside the cavity 15. The anti-detachment block 24 can abut against the upper surface of the interceptor plate 11, which prevents the ground insertion part 16 from easily detaching from the interceptor plate 11 when the interceptor plate 11 is in a suspended state.

[0046] The implementation principle of this application embodiment is as follows: First, the walking mechanism 1 moves to the section of the river that needs to be cleaned. Then, the robotic arm 2 moves both the connecting seat 9 and the mounting seat 10 above the river. The robotic arm 2 further moves the connecting seat 9 and the mounting seat 10 toward the river. After reaching the target height, the drive component 12 on the mounting seat 10 near the upstream of the river is activated first. This causes the intercepting plate 11 near the upstream of the river to be inserted into the river under the action of the drive component 12. Under the action of the transmission part 19 of the ground insertion part 16, the movable plate 17 rotates out from both sides of the connecting plate and abuts against the river slope. The intercepting plate 11 cuts off the water flow in the river. When the silt in the river is exposed, the drive component 12 on the mounting seat 10 near the downstream of the river is activated, causing another intercepting plate 11 to fall down to prevent the river water from flowing back.

[0047] Next, the connection between the connecting seat 9 and the mounting seat 10 is disconnected, allowing the robotic arm 2 to drive the connecting seat 9 to move independently of the two mounting seats 10. The robotic arm 2 moves the connecting seat 9 closer to the bottom of the riverbed. Then, the drive motor mounted on the connecting seat 9 is activated, causing the dredging arc cover 7 to rotate out of the fixed arc cover 6. As the dredging arc cover 7 rotates around its own axis, it excavates the silt in the riverbed. When the dredging arc cover 7 rotates to a position where the opening direction is opposite to the opening direction of the fixed arc cover (i.e., rotated 180° from the initial position), the robotic arm 2 drives the connecting seat 9 to move out of the two mounting seats 10. The silt is removed and the dredging arc cover 7 is rotated again by the drive motor to pour the silt out and place it on the bank. The above steps are repeated until the silt in the current segment is completely cleared. Then the connection between the interception seat and the mounting seat 10 is restored. The drive component 12 closest to the downstream of the river is activated first, so that the interception plate 11 rises. The ground insert 16 drives the movable plate 17 that has been rotated out to rotate back under its own gravity. Then the other drive component 12 is activated, so that the other interception plate 11 also rises, so that the water flow that was blocked in the river can flow again. The above operations are repeated until the silt in all locations in the river is completely cleared.

[0048] Example 2

[0049] This application also provides a dredging method, which uses a river dredging device as described in Embodiment 1 above, and includes the following steps:

[0050] S100: Move the walking mechanism 1 to the location on the river where silt needs to be cleared;

[0051] S200: The connecting seat 9 and the mounting seat 10 are moved to the upper part of the river channel by the robotic arm 2. At this time, the length direction of the connecting seat 9 is consistent with the length direction of the river channel.

[0052] S300: The drive unit 12 near the upstream starts first, and the interceptor plate 11 descends to intercept the water flow in the river. Then the drive unit 12 near the downstream starts, so that the two interceptor plates 11 can intercept the water flow in the river section that needs to be cleared of silt.

[0053] S400: Disconnect the connection between the connecting seat 9 and the mounting seat 10, and drive the connecting seat 9 to descend, so that the dredging arc cover 7 is above the silt in the river channel.

[0054] S500: Start the motor used to drive the dredging arc cover 7 to rotate around its own axis, so that the dredging arc cover 7 cleans the silt exposed in the river channel until all the silt in the river channel between the two intercepting plates 11 is cleaned.

[0055] S600: After cleaning, reconnect the connector 9 to the mounting base 10, then start the drive unit 12 near the downstream first, and then start the drive unit 12 near the upstream to complete the recovery of the interceptor plate 11, thus completing the silt removal of the current section of the river.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
