Description

Technical Field

[0001] This utility model relates to the field of suction device technology, and in particular to a suction device for polluted river sediment. Background Technology

[0002] The riverbed sediment suction device is an environmental engineering equipment specifically designed to remove pollutant-rich sediment from the bottom of rivers and lakes. Its core objective is to safely remove sediment without significantly disturbing the water body and avoiding secondary pollution. The device typically consists of a suction head, a mud pump, and a delivery pipeline. During operation, the negative pressure of the mud pump mixes the sediment with water to form a slurry, which is then sucked up and transported through pipelines to a designated location for further treatment. This effectively reduces endogenous pollution, improves black and odorous water bodies, and increases the flow capacity of rivers.

[0003] However, in the use of existing river polluted sediment suction devices, the corresponding support frame cannot be independently fine-tuned when placed on the bank. This results in instability on uneven ground, affecting the stability of the sludge pump's suction head during suction and potentially causing sludge to spread. Therefore, those skilled in the art have provided a river polluted sediment suction device to solve the problems mentioned in the background art. Utility Model Content

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-5 A riverbed polluted sediment suction device includes an assembly bracket 1, a horizontal adjustment mechanism 2 fixed to the outside of the assembly bracket 1 by bolts, a winding mechanism 3 installed at the bottom of the horizontal adjustment mechanism 2, a wire rope 4 installed on the outside of the winding mechanism 3, a mud pump 5 fixed to one end of the wire rope 4, adjustment mechanisms 6 installed at the four corners of the bottom of the assembly bracket 1, an installation bracket 7 fixed to the outside of the assembly bracket 1, a maintenance mechanism 8 fixed to the end of the installation bracket 7 away from the assembly bracket 1, and a conveying pipe 9 connected to the outside of the mud pump 5.

[0026] The adjustment mechanism 6 includes a mounting plate 61, with a mounting housing 62 fixed to the bottom of the mounting plate 61. A rotating rod 64 is connected to the inside of the mounting housing 62 via a bearing. A handle bracket 63 is fixed to one end of the rotating rod 64. A first bevel gear 65 is fixed to the outside of the rotating rod 64. A second bevel gear 66 meshes with the bottom of the first bevel gear 65. A ball screw 67 is fixed to the axis of the second bevel gear 66. A ball nut 68 is threaded onto the outside of the ball screw 67. A fixed... A fixed bracket 69 is provided, and a lifting frame 610 is fixed to the outside of the fixed bracket 69. A self-locking universal wheel 611 is installed at the bottom of the lifting frame 610. The mounting plate 61 and the assembly bracket 1 are fixedly connected. The interior of the mounting housing 62 is provided with a limiting groove to accommodate the vertical movement of the lifting frame 610. The outside of the handle 63 is provided with anti-slip texture. The second bevel gear 66 is fixedly connected to the ball screw 67 through a connecting shaft. The outside of the connecting shaft is connected to a metal pad through a bearing, and the metal pad is fixedly connected to the mounting housing 62.

[0027] Specifically, by setting up the adjustment mechanism 6, when pumping polluted sediment from the riverbed, the assembly bracket 1 is first moved to the corresponding riverbank. When the height of the four corners of the assembly bracket 1 needs to be adjusted, the handle 63 is manually turned to rotate the rotating rod 64. This, in turn, drives the first bevel gear 65 to rotate the second bevel gear 66, which in turn drives the ball screw 67. The ball nut 68 on the outside of the ball screw 67 can move vertically. The fixed bracket 69 on the outside of the ball nut 68 drives the lifting frame 610 to move vertically, thereby fine-tuning the height of the corresponding feet of the assembly bracket 1. This allows the assembly bracket 1 to adapt to uneven ground after placement, ensuring that the device remains horizontal and stable on riverbanks and slopes. After starting the winding mechanism 3, the lifting of the wire rope 4 and the mud pump 5 is controlled, ensuring that the suction head of the mud pump 5 remains stable during pumping. This helps improve the dredging accuracy, avoids the diffusion of sediment caused by shaking, and facilitates the smooth progress of the pumping operation.

[0028] Furthermore, the maintenance mechanism 8 includes a fixing plate 81, a first protective sleeve 82 fixed to one side of the fixing plate 81, a second protective sleeve 83 hinged to the outside of the first protective sleeve 82, a first connecting plate 84 installed on the outside of the first protective sleeve 82, a second connecting plate 85 fixed to the outside of the second protective sleeve 83, a first semi-threaded rod 86 installed on one side of the first connecting plate 84, a second semi-threaded rod 87 installed on one side of the second connecting plate 85, and a limit nut 88 threadedly connected to the outside of the first semi-threaded rod 86 and the second semi-threaded rod 87. The fixing plate 81 and the mounting bracket 7 are fixedly connected. The inner walls of the second protective sleeve 83 and the first protective sleeve 82 are both in contact with the conveying pipe 9. The corresponding surfaces of the first connecting plate 84 and the second connecting plate 85 are in contact. The radius of the first semi-threaded rod 86 is equal to the radius of the second semi-threaded rod 87.

[0029] Specifically, by setting up a maintenance mechanism 8, when the polluted riverbed sediment pumped by the mud pump 5 is discharged through the conveying pipe 9, which is a rubber hose, when the conveying pipe 9 is in place, the corresponding surface of the conveying pipe 9 can be attached to the outside of the first protective sleeve 82. Then, the second protective sleeve 83 on the outside of the first protective sleeve 82 is rotated. After the corresponding surfaces of the second connecting plate 85 and the first connecting plate 84 on the outside of the second protective sleeve 83 are attached, the limiting nut 88 is threadedly connected to the first semi-threaded rod 86 and the second semi-threaded rod 87, which conveniently completes the fixation between the second protective sleeve 83 and the first protective sleeve 82. By clamping the inner walls of the first protective sleeve 82 and the second protective sleeve 83 to the outside of the conveying pipe 9, the outside of the conveying pipe 9 can be clamped and limited during suction, making it easy to place and position the mud outlet end of the conveying pipe 9, which is beneficial to the suction.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
