Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and in particular to a river channel desilting device used in the construction of high-efficiency water conservancy projects. Background Art

[0002] In water conservancy projects, silt accumulation at the bottom of the river is a common problem, which not only affects the smoothness of the river, but also may have a negative impact on the river's ecological environment. Therefore, it is particularly important to develop an efficient and professional river dredging equipment;

[0003] Since the depth of each river channel, water flow conditions and silt accumulation are different, the cleaning shovel may not be able to adapt to all scenarios. In a shallow river channel, a cleaning shovel that is too high may damage the rocks or other structures at the bottom of the river channel; in a deeper river channel, a cleaning shovel that is too low may not be able to reach the silt layer, resulting in poor dredging effect. In view of the above defects, the present utility model is proposed. Utility Model Content

[0024] The lifting assembly 5 drives the cleaning shovel 4 to lift through the adjusting assembly 6, and the adjusting assembly 6 is used to adjust the use angle of the cleaning shovel 4;

[0025] The lifting assembly 5 includes an electric turntable 51 provided on the hull 1, a fixed frame 52 is provided on the electric turntable 51, a lead screw 53 rotates in the fixed frame 52, a motor 54 is provided on the fixed frame 52 at the top of the lead screw 53, the output end of the motor 54 penetrates the fixed frame 52 and is connected to one end of the lead screw 53, a plurality of groups of guide rods 55 are vertically arranged on the inner wall of the fixed frame 52, a sliding plate 56 slides on the guide rods 55, and the sliding plate 56 is threadedly connected to the lead screw 53, and an adjusting assembly 6 is provided on the left side of the sliding plate 56.

[0026] When the staff needs to use the cleaning shovel 4, first start the motor 54 through the controller to make the motor 54 drive the lead screw 53 to rotate in the fixed frame 52, then start the electric turntable 51 to make the electric turntable 51 drive the cleaning shovel 4 to rotate, and then the lead screw 53 acts on the sliding plate 56 while rotating, so that the sliding plate 56 moves up and down on the lead screw 53 and slides on the guide rods 55 until the cleaning shovel 4 fits the bottom of the river, and then drive the hull 1 to move through the propeller 2 to make the cleaning shovel 4 clean the silt in the river.

[0027] There are two sets of guide rods 55, and the two sets of guide rods 55 are symmetrically arranged on the inner wall of the fixed frame 52 at the front and rear ends of the lead screw 53 respectively. Through this design, the stability of the sliding plate 56 sliding up and down on the lead screw 53 can be ensured, and the shaking of the sliding plate 56 during movement can be prevented, thereby affecting the effect of the cleaning shovel 4 for cleaning silt.

[0028] The motor 54 is internally provided with a power supply, and the motor 54 is wirelessly connected to the controller through a wireless module. Through this design, it is convenient for the staff to operate the motor 54 on the shore, enabling the staff to stay away from the motor 54, avoiding the influence of harsh environments such as high temperature, high altitude, toxicity, and dust on the site, and remotely controlling the motor 54, thus ensuring the personal safety of the operators.

[0029] The adjusting assembly 6 includes a rotating groove 61 opened on the left surface of the sliding plate 56. A rotating rod 62 is rotated in the rotating groove 61. A brake disc 63 is provided at the front end of the rotating rod 62. A plurality of groups of limiting grooves 64 are opened on the outer wall of the brake disc 63. Two sets of movable frames 65 are arranged on the left surface of the sliding plate 56. Connecting rods 66 are horizontally arranged on the inner walls of the movable frames 65. Sliders 67 are slid on the connecting rods 66. Positioning rods 68 are provided on the side surfaces of the sliders 67 facing the limiting grooves 64. Springs 69 are wound around the surfaces of the connecting rods 66 between the connecting rods 66 and the movable frames 65. A cleaning shovel 4 is provided at the bottom of the rotating rod 62.

[0030] When the staff needs to process the sludge in the cleaning shovel 4, first pull the slider 67 in the direction away from the brake disc 63, so that the slider 67 slides on the connecting rod 66 and squeezes the spring 69 against the inner wall of the movable frame 65 until the slider 67 drives the positioning rod 68 to slide out of the limiting groove 64. Then rotate the cleaning shovel 4, so that the cleaning shovel 4 drives the rotating rod 62 to rotate in the rotating groove 61, and the rotating rod 62 drives the brake disc 63 to rotate synchronously while rotating. Until the cleaning shovel 4 rotates to the required angle, at this time the limiting groove 64 is aligned with the positioning rod 68, and then release the slider 67. Use the restoring force of the spring 69 to push the slider 67 to reset and slide on the connecting rod 66, and insert the positioning rod 68 into the limiting groove 64 to achieve the purpose of adjusting the use angle of the cleaning shovel 4.

[0031] There are eight groups of limiting grooves 64, and the eight groups of limiting grooves 64 are all arranged equidistantly around the outer wall of the brake disc 63. Through this design, the cleaning shovel 4 can drive the rotating rod 62 to rotate in the rotating groove 61, so that the rotating rod 62 drives the brake disc 63 to rotate synchronously, making the eight groups of limiting grooves 64 align with the positioning rod 68 in turn, and then using the restoring force of the spring 69 to push the positioning rod 68 into the limiting groove 64 to achieve the purpose of adjusting the eight use directions of the cleaning shovel 4.

[0032] The slider 67 is designed in a T shape. Both the upper and lower ends of the slider 67 are in contact with the inner wall of the movable frame 65. Through this design, it is convenient for the staff to push the slider 67, so that the slider 67 slides on the connecting rod 66 and squeezes the spring 69, preventing the situation of slippery hands when pulling the slider 67.

[0033] The above is only the preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
