Description

Technical Field

[0001] This application relates to the field of dredging devices for water conservancy projects, and in particular to a high-efficiency dredging device for water conservancy projects. Background Technology

[0002] River dredging is an important water conservancy project. By dredging rivers, we can increase river capacity, restore smooth water flow, purify water bodies, maintain ecological balance, remove harmful substances, and ensure water safety.

[0003] Some riverbeds are low-lying with a significant height difference from the ground. For such riverbeds, the existing dredging method involves moving the excavation equipment to the riverbed and setting up a basket and loading truck on the ground. The basket is first moved above the riverbed, and then the excavation equipment is used to dredge the silt from the riverbed and put it into the basket. The basket is then used to move the silt to the loading truck. The whole process is inefficient. Utility Model Content

[0004] In order to improve the dredging efficiency of rivers with low riverbeds, this application provides a high-efficiency dredging device for water conservancy projects.

[0005] The high-efficiency dredging device for water conservancy projects provided in this application adopts the following technical solution:

[0006] A high-efficiency dredging device for water conservancy projects includes a moving mechanism, a housing, a conveying pipeline, a robotic arm, and a dredging bucket. The housing is installed on the moving mechanism and is used to hold silt. One end of the conveying pipeline is installed on the housing, and the other end is connected to the silt bucket. The conveying pipeline is used to transport the silt in the silt bucket to the housing. The robotic arm is installed on the conveying pipeline, and the dredging bucket is connected to the end of the robotic arm away from the conveying pipeline. The robotic arm is used to drive the dredging bucket to excavate the silt in the river channel.

[0007] By adopting the above technical solution, during dredging, a moving mechanism is used to move the container, conveying pipeline, and robotic arm to the bottom surface of the riverbed, extending the conveying pipeline and robotic arm above the riverbed. Then, the robotic arm drives the shovel bucket to excavate the silt from the riverbed, transferring the silt from the shovel bucket to the silt hopper. The conveying pipeline then transports the silt from the silt hopper to the container. Compared to existing methods, the shovel bucket can continuously transport silt to the silt hopper without waiting, thus improving dredging efficiency.

[0008] Optionally, the delivery pipe may be detachably connected to a support rod.

[0009] By adopting the above technical solutions, the stability of the conveying pipeline during operation is enhanced, preventing the pipeline from sagging or deforming due to the weight generated during sludge transport, thereby improving the reliability and safety of dredging operations. Simultaneously, the detachable connection between the support rod and the conveying pipeline facilitates adjustment of the support position or replacement of components according to actual working conditions, improving the flexibility and ease of maintenance of the device.

[0010] Optionally, the support rod is a lifting rod, and the conveying pipe is hinged to the box body.

[0011] By adopting the above technical solution, the angle of the conveying pipeline can be adjusted according to the riverbed depth, which further enhances the operational flexibility of the equipment and improves the efficiency and applicability of dredging and conveying silt.

[0012] Optionally, a supporting semi-ring is provided at one end of the support rod near the conveying pipe, and the concave surface of the support plate is used for the outer wall of the conveying pipe to abut against.

[0013] By adopting the above technical solution, the concave surface of the supporting semi-ring is used for the outer wall of the conveying pipeline to abut against, thereby achieving effective support for the conveying pipeline, enhancing the stability of the conveying pipeline during operation, reducing the possibility of the conveying pipeline shifting or being damaged due to external vibration or gravity, and thus improving the overall reliability of dredging operations.

[0014] Optionally, the concave surface of the supporting semi-ring is provided with a plurality of balls, which are evenly distributed on the concave surface of the supporting semi-ring.

[0015] By adopting the above technical solution, the frictional resistance between the conveying pipeline and the supporting semi-ring is reduced, making the conveying pipeline move more smoothly when it is displaced under force. At the same time, the evenly distributed design of multiple ball bearings further ensures the balance of force distribution, avoiding excessive local wear that could lead to structural instability, thereby improving the overall service life and operational reliability of the device. It is suitable for dredging operations that require frequent adjustments to angle or position, significantly improving operational flexibility and work efficiency.

[0016] Optionally, the conveying pipeline includes a sludge pipe and a sludge pump, wherein the sludge pump is installed on the sludge pipe.

[0017] Optionally, the sludge pipe includes a connecting section and an installation section, the sludge pump is installed in the installation section, and the installation section and the connecting section are detachably connected.

[0018] By adopting the above technical solution, the sludge pipe is divided into a connection section and an installation section, and the installation section and the connection section are detachably connected. This facilitates adjustments to the length and structure of the conveying pipeline according to actual needs, while simplifying the assembly, maintenance, and transportation of the equipment. Furthermore, it improves the flexibility and adaptability of the equipment, better meeting the needs of different river dredging scenarios.

[0019] Optionally, the connecting segment is provided in multiple segments, and adjacent connecting segments are detachably connected.

[0020] By adopting the above technical solutions, adjustments can be made flexibly according to actual dredging needs, making it easy to adapt to river environments of different depths and widths. The detachable connection between adjacent sections simplifies the assembly and disassembly process, reduces transportation difficulties, and improves maintenance convenience. Furthermore, it helps reduce the likelihood of the entire equipment becoming unusable due to damage to a single component, thus enhancing the overall reliability and economy of the equipment.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The integrated design of the container, conveying pipeline, robotic arm and hopper is carried by a mobile mechanism, eliminating the need for additional basket devices and loading vehicles, reducing intermediate transfer links, simplifying the dredging process and significantly improving dredging efficiency;

[0023] 2. By setting up a support rod and setting a support semi-ring at the end of the support rod near the conveying pipe, multiple balls are rolled on the concave surface of the support semi-ring, which not only supports the conveying pipe but also improves the smoothness of the conveying pipe's movement relative to the riverbed.

[0024] 3. The sludge pipe includes a connecting section and an installation section. The sludge pump is installed in the installation section, allowing for separate cleaning of the pump. Furthermore, multiple connecting sections are provided, allowing for the selection of an appropriate number for installation based on specific working conditions, thus improving the flexibility of the dredging device.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a high-efficiency dredging device for water conservancy projects.

[0031] Reference Figure 1-3 A high-efficiency dredging device for water conservancy projects includes a moving mechanism 1, a housing 2, a conveying pipe 3, a robotic arm 4, and a dredging hopper 5. The housing 2 is installed on the moving mechanism 1 and is used to hold silt. One end of the conveying pipe 3 is installed on the housing 2, and the other end is connected to a silt hopper 31. The conveying pipe 3 is used to transport the silt in the silt hopper 31 to the housing 2. The robotic arm 4 is installed on the conveying pipe 3, and the dredging hopper 5 is connected to the end of the robotic arm 4 away from the conveying pipe 3. The robotic arm 4 is used to drive the dredging hopper 5 to excavate the silt in the riverbed. During dredging, the moving mechanism 1 moves the housing 2, the conveying pipe 3, and the robotic arm 4 to the bottom surface of the riverbed, extending the conveying pipe 3 and the robotic arm 4 above the riverbed. Then, the robotic arm 4 drives the dredging hopper 5 to excavate the silt from the riverbed, and the silt in the dredging hopper 5 is moved to the silt hopper 31. The conveying pipe 3 then transports the silt in the silt hopper 31 to the housing 2. Compared to existing methods, the sludge hopper 5 can continuously transport sludge into the sludge hopper 31 without waiting, thus improving dredging efficiency.

[0032] The structure of the box body 2 plus the moving mechanism 1 can be directly used by existing open-top cargo trucks.

[0033] The robotic arm 4 includes multiple lever arms that are hinged in sequence and hydraulic cylinders for driving the rotation of each lever arm. The movement of the robotic arm 4 can be controlled by a remote terminal, which is a conventional method in the prior art and will not be described in detail in this application.

[0034] The conveying pipeline 3 includes a sludge pipe 32 and a sludge pump 33. The sludge pump 33 is installed in the sludge pipe 32 and is used to convey the sludge in the sludge hopper 31 to the housing 2.

[0035] Furthermore, in this embodiment, the sludge pipe 32 includes a connecting section 321 and an installation section 322, wherein the sludge pump 33 is installed in the installation section 322, and the installation section 322 and the sludge section are detachably connected. The detachable connection methods include, but are not limited to, threaded connection, bolt connection, etc.

[0036] In this embodiment, two connecting segments 321 are provided, and the two connecting segments 321 are respectively connected to the two ends of the mounting segment 322. In other embodiments, the number of connecting segments 321 may be more than two, and adjacent connecting segments 321 may be detached and connected, so as to select an appropriate number of connecting segments 321 to form an appropriate length of sludge pipe 32 according to the actual working conditions.

[0037] Furthermore, the conveying pipe 3 is detachably connected to a support rod 6. One end of the support rod 6 has multiple inclined rods 61, which are used to abut against the ground. If necessary, the inclined rods 61 can be fixed to the ground with expansion bolts.

[0038] The end of the support rod 6 furthest from the diagonal rod 61 is bolted to a support semi-ring 62, the concave surface of which is used for the sludge pipe 32 to abut against. Thus, the support rod 6 provides support for the sludge pipe 32 on which the robotic arm 4 is mounted, enhancing the stability of the conveying pipeline 3 during operation, reducing the possibility of displacement or damage to the conveying pipeline 3 due to external vibration or gravity, and thereby improving the overall reliability of the dredging operation.

[0039] In this embodiment, the support rod 6 is a lifting rod, and the sludge pipe 32 is hinged to the box body 2 through the hinge 34. The hinge 34 is welded and fixed to the sludge pipe 32, and the hinge 34 is detachably connected to the box body 2 by bolts.

[0040] Furthermore, multiple rolling balls 63 are evenly distributed on the concave surface of the supporting semi-ring 62, providing a rolling connection. This design reduces the frictional resistance between the conveying pipe 3 and the supporting semi-ring 62, allowing the conveying pipe 3 to move more smoothly under stress. Simultaneously, the even distribution of multiple rolling balls 63 further ensures the balance of force, preventing excessive local wear that could lead to structural instability, thereby improving the overall service life and operational reliability of the device.

[0041] The implementation principle of a high-efficiency dredging device for water conservancy projects is as follows: Before dredging, the dredging device is installed: First, the moving mechanism 1 is used to move the box 2 to the ground next to the river; then, a support rod 6 with the height adjusted is installed between the moving mechanism 1 and the river, with one end of the support rod 6 near the bottom abutting or connecting to the ground; then, the sludge pipe 32, which is equipped with the mechanical arm 4 and the sludge pump 33, is hinged to the box 2 through the hinge 34, and the sludge pipe 32 is then mounted on the support semi-ring 62.

[0042] During dredging, the robotic arm 4 is activated, and the robotic arm 4 drives the dredging bucket 5 to dig out the silt. The dredged silt is then transported to the silt bucket 31, and the silt pump 33 transports the silt in the silt bucket 31 to the housing 2.

[0043] In a wider river channel, the sludge pipe 32 is moved relative to the supporting semi-ring 62 by the moving mechanism 1 to change the range of sludge dredging.

[0044] 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.
