Description

Technical Field

[0001] The utility model belongs to the technical field of waterway dredging, in particular to a port waterway dredging device. Background Art

[0002] The formation of port silt is the result of a combination of natural and human factors. Natural factors, including silt sources, topography, and climate, jointly determine the transport and deposition patterns of silt in port areas. Human factors, such as port construction, ship activity, and pollution emissions, further exacerbate the silt formation process. Therefore, the impact of these factors on silt formation must be fully considered during port planning, construction, and operation, and appropriate measures must be implemented to reduce silt generation and accumulation.

[0003] According to patent authorization announcement number: CN221321099U, a waterway dredging device is proposed. This utility model discloses a waterway dredging device, comprising: a dredging pipe head; the top of the dredging pipe head is connected to a ship-borne mud pump via a pipeline, and the bottom of the dredging pipe head is fixedly connected to a fixed bottom ring via screws; a supporting inner frame is provided inside the dredging pipe head, a motor is installed on the top of the supporting inner frame, and a hemispherical mesh cover is installed inside the bottom of the dredging pipe head; a rotating dredging head, the rotating dredging head is installed at the connection between the dredging pipe head and the fixed bottom ring, the hemispherical mesh cover is located on the top of the rotating dredging head, and the motor is connected to the top of the rotating dredging head. The motor of the utility model drives the rotating dredging head to rotate, and the rotating dredging head stirs the silt, causing the silt to form slurry. The slurry is sucked into the dredging pipe head under the influence of suction force, and the dredging pipe head transports the slurry to the dredging ship through a pipeline to ensure the waterway dredging effect.

[0004] The function of the mesh in the above-mentioned existing channel dredging device is to intercept large pieces of material carried in the silt and only allow materials below the mesh diameter to pass through.

[0029] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The present invention provides a device for clearing silt from a port or waterway. Figure 1-5 As shown, it includes a first dredging pipe head 1, a motor 4 is installed inside the first dredging pipe head 1, the motor 4 is fixedly connected to the inner wall of the first dredging pipe head 1 through a second mounting bracket 5, and the output end of the motor 4 is fixedly connected to a connector 6;

[0031] The second dredging pipe head 2 is connected to the lower end of the first dredging pipe head 1. A first mounting bracket 22 is provided inside the second dredging pipe head 2. A rotating rod 7 is rotatably connected to the middle of the first mounting bracket 22 through a bearing. A docking hole 71 for docking with the connector 6 is provided on the top of the rotating rod 7. A plurality of paddle blades 8 are provided around the outer wall of the rotating rod 7. A mesh plate 9 is sleeved on the upper end of the rotating rod 7; and

[0032] Two sets of connecting components 3 are symmetrically arranged between the first dredging pipe head 1 and the second dredging pipe head 2, and are used to guide the docking or separation of the first dredging pipe head 1 and the second dredging pipe head 2, and at the same time limit the mesh plate 9 to fix or release the limit;

[0033] A first connecting ring 11 is provided at the lower open end of the first dredging pipe head 1, and a second connecting ring 2 is provided at the upper open end of the second dredging pipe head 2; a limiting groove 23 for accommodating the mesh plate 9 is provided between the first connecting ring 11 and the second connecting ring 12; the cross-section of the lower end of the joint 6 is a regular polygonal structure.

[0034] In this embodiment, the dredging pipe head may cause some small objects to get stuck in the mesh during the process of sucking silt, and then the mesh cover needs to be removed for cleaning or replacement after a period of dredging. However, the existing mesh cover is not convenient to disassemble and assemble, which takes a lot of time and affects the subsequent dredging operation. Therefore, this solution sets two sets of connecting components 3 between the first dredging pipe head 1 and the second dredging pipe head 2, and uses the connecting components 3 to achieve rapid docking or separation of the first dredging pipe head 1 and the second dredging pipe head 2, thereby facilitating the disassembly or installation of the mesh plate 9 between the first dredging pipe head 1 and the second dredging pipe head 2, greatly improving the convenience of installation or disassembly of the mesh plate 9, simplifying disassembly and assembly, and reducing the labor intensity of workers in disassembly and installation.

[0035] Specifically, a through hole is opened in the middle of the mesh plate 9 in this scheme, the inner diameter of the through hole is matched with the outer diameter of the upper end of the rotating rod 7, and the through hole in the center of the mesh plate 9 is sleeved on the rotating rod 7, and then when the first dredging pipe head 1 and the second dredging pipe head 2 are connected through the connecting component 3, the outer edge of the mesh plate 9 is in the limiting groove, and the first connecting ring 11 and the second connecting ring 12 press and limit the mesh plate 9 to achieve the limited and fixed installation of the mesh plate 9; on the contrary, when the mesh plate 9 needs to be disassembled, cleaned or replaced, the first dredging pipe head 1 and the second dredging pipe head 2 are separated through the connecting component 3, and the first connecting ring 11 and the second connecting ring 12 will release the pressure on the mesh plate 9, and then the mesh plate 9 only needs to be removed from the rotating rod 7.

[0036] It should be noted that the first dredging pipe head 1 of this scheme is the same as the existing technology. An external dredging pump is connected to the upper end of the first dredging pipe head 1 through a pipeline. The motor is used to drive the paddle 8 to stir the silt, which is then sucked out by the external dredging pump, and large objects are intercepted by the mesh plate 9.

[0037] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the connection component 3 includes:

[0038] A fixing block 301 is formed integrally with one side wall of the first desilting pipe head 1, and an inner groove 302 is formed on the outer side wall of the fixing block 301;

[0039] Two guide rods 303 are symmetrically arranged inside the inner groove 302, with the upper ends of the guide rods 303 fixedly connected to the top wall of the inner groove 302, and the lower ends of the guide rods 303 are connected to the upper end of the second connecting ring 21;

[0040] A movable seat 304 slidably mounted on the guide rod 303 along the length direction of the guide rod 303;

[0041] A spring 305 sleeved on the lower end of the guide rod 303, the spring 305 being located between the second connecting ring 21 and the movable seat 304; and

[0042] The rotating seats 308 are symmetrically arranged on the two side walls of the upper end of the second dredging pipe head 2, and the lower end of the movable seat 304 is rotatably connected to the rotating seat 308 through a shaft.

[0043] In this embodiment, after the first dredging pipe head 1 is separated from the second dredging pipe head 2, the second dredging pipe head 2 can rotate relative to the first dredging pipe head 1 through the relationship between the movable seat 304 and the rotating seat 308. Therefore, after the first dredging pipe head 1 and the second dredging pipe head 2 are separated parallel to each other for a distance, the mesh plate 9 can be completely exposed by rotating the second dredging pipe head 2, so that the mesh plate 9 can be removed and installed later.

[0044] When the first dredging pipe head 1 and the second dredging pipe head 2 need to be docked, the first dredging pipe head 1 and the second dredging pipe head 2 are placed on the same horizontal line, and the compressed spring 305 pushes the movable seat 304 upward to achieve pre-docking of the first dredging pipe head 1 and the second dredging pipe head 2.

[0045] It should be noted that during the docking process between the first dredging pipe head 1 and the second dredging pipe head 2, the connector 6 will also be inserted into the docking hole 71. If the docking position of the connector 6 and the docking hole 71 is misaligned, it is only necessary to slowly rotate the rotating rod 7 to correct the misalignment of the connector 6 and the docking hole 71 and dock them.

[0046] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the connecting component 3 also includes a screw 306 threadedly connected to the upper end of the movable seat 304; and a screw hole 307 opened on the inner wall of the inner groove 302; the inner diameter of the screw hole 307 is adapted to the outer diameter of the threaded end of the screw 306, and the center of the screw hole 307 is on the same horizontal line as the axis of the screw 306.

[0047] In this embodiment, when the first dredging pipe head 1 and the second dredging pipe head 2 are docked, the spring 305 will push the movable seat 304 to contact the top of the inner groove 302. At this time, the screw 306 is just aligned with the screw hole 307. Then, only the screw 306 needs to be tightened to fix the movable seat 304. The first dredging pipe head 1 and the second dredging pipe head 2 are also in a completely fixed docking state.
