[0001] This utility model relates to the field of river cleaning technology, specifically to a silt removal device for river restoration. Background Technology

[0002] In the process of ecological restoration of rivers, it is usually necessary to use silt removal equipment to remove silt.

[0003] Chinese patent document CN212078067U discloses a riverbed silt removal device for river restoration. This device uses an electric telescopic rod to drive a motor to move up and down. The motor drives the silt cutting blade to rotate. When the boat moves to the left, the electric telescopic rod, motor and silt cutting blade can break up the silt and rocks at the bottom of the riverbed. The broken silt can be sucked away by the pump, second spring tube and sludge discharge pipe.

[0004] However, when the above solution is used, because there are aquatic plants and garbage on the bottom of the riverbed, when the silty water is sucked through the pipe, the aquatic plants and garbage on both sides of the pipe will enter the pipe along with the silty water through the suction of the pump, causing blockage of the pipe and pump. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a silt removal device for river restoration.

[0029] Example 1

[0030] like Figure 1-3 As shown, the present invention proposes a silt removal device for river restoration, comprising a pipe 1, an agitator 2, a mounting plate 4, and a drive assembly;

[0031] Mounting plate 4 is mounted on the hull, and a connecting rod 3 for extending to the bottom of the water during dredging is rotatably mounted on one end of mounting plate 4; wherein, the connecting rod 3 is rotatably mounted on one end of mounting plate 4 through a rotating shaft, universal bearing and other structures.

[0032] Pipe 1 is installed at the bottom of connecting rod 3 and is connected to the external pump body pipe in the dredging state to transport sludge water to the inside of the ship;

[0033] The drive assembly is installed in the middle of the pipe 1 and extends to the inside of the pipe 1; the agitator 2 is installed at the bottom of the drive assembly and inserted into the bottom of the pipe 1 for use in dredging. The agitator 2 rotates at the bottom of the pipe 1 by the drive assembly, mixing the sludge deposited at the bottom of the water with the water. The agitator 2 is cylindrical and cage-like in shape, and the bottom of the agitator 2 is arc-shaped to prevent water head collision and debris such as aquatic plants from entering the inside of the pipe 1 and causing blockage of the external pump.

[0034] It should be noted that the shape of pipe 1 is Z-shaped, and both ends are arranged vertically. One end of the drive component extends along the central axis of one end of pipe 1 to the inside of pipe 1.

[0035] In this embodiment, the mounting plate 4 is installed on the hull, and the length of the connecting rod 3 is set to be greater than the water depth. The pipe 1 is moved towards the silt at the bottom of the water by gravity, so that the connecting rod 3 rotates on the mounting plate 4 to an inclined position. The connecting rod 3 drives the pipe 1 to be placed in the water at an inclination by gravity, so that the agitator 2 comes into contact with the silt. This avoids the need to adjust the height of the agitator 2 during the dredging process when the connecting rod 3 is placed vertically. At the same time, the driving component drives the agitator 2 to rotate at one end of the pipe 1, so that the agitator 2 mixes the silt with the water. The silt water is discharged to the hull by an external pump through the pipe 1 for filtration. At the same time, the shape of the agitator 2 and the fact that the agitator 2 is inserted into the inner side of one end of the pipe 1 make the agitator 2 block the impurities in the water, preventing the external pump from getting blocked.

[0036] Example 2

[0037] like Figure 2As shown, the silt removal device for river restoration proposed in this utility model, compared with Embodiment 1, has a drive structure including a motor 6 and a rotating shaft 7.

[0038] The motor 6 is installed in the middle of the pipe 1 and its output shaft is coaxially arranged with one end of the pipe 1. It should be noted that a sealing shell 5 is provided on the outside of the motor 6, and the sealing shell 5 is sealed to the pipe 1 to prevent water from entering and damaging the motor 6 when in use.

[0039] The rotating shaft 7 is mounted on the output shaft of the motor 6, and one end extends along the central axis of one end of the pipe 1 to the inner side of one end of the pipe 1 and is connected to the agitator 2.

[0040] In an optional embodiment, it should be noted that a spiral plate 8 is provided on the outer side of the rotating shaft 7 and on the inner side of one end of the pipe 1, and there is a small gap between the edge of the spiral plate 8 and the inner wall of the pipe 1. This is used so that when the rotating shaft 7 drives the agitator 2 to rotate, the rotating shaft 7 drives the spiral plate 8 to rotate on the inner side of the pipe 1, thereby increasing the speed at which sludge water is transported to the inner side of the pipe 1.

[0041] In this embodiment, the motor 6 is sealed and installed on the pipe 1 by the sealing shell 5, and the motor 6 drives the rotating shaft 7 to rotate in the pipe 1. The rotating shaft 7 drives the agitator 2 to rotate to agitate the sludge and block the debris. When the agitator 2 rotates, the rotating shaft 7 drives the spiral plate 8 to rotate inside the pipe 1, so that the spiral plate 8 carries the sludge water into the pipe 1, thereby improving the sludge water transportation efficiency.

[0042] Example 3

[0043] like Figure 3 As shown, the silt removal device for river restoration proposed in this utility model, compared with Embodiment 1, in this embodiment, the connecting rod 3 includes an installation rod 31, an adjustment rod 32 and a limiting rod 33;

[0044] Mounting rod 31 is installed on the outside of pipe 1;

[0045] The limiting rod 33 is rotatably mounted on one end of the mounting plate 4;

[0046] The number of adjusting rods 32 is at least one. The adjusting rod 32 is installed between the mounting rod 31 and the limiting rod 33 by bolts to place the pipe 1 in the river silt during dredging.

[0047] In an optional embodiment, one end of the limiting rod 33 and the adjusting rod 32 are provided with a protrusion 34, and the other end of the adjusting rod 32 and one end of the mounting rod 31 are provided with a groove 35. When the mounting rod 31, the adjusting rod 32 and the limiting rod 33 are installed together, the protrusion 34 is accommodated in the groove 35. The protrusion 34 is non-circular in shape, so that when the protrusion 34 is installed inside the groove 35, the protrusion 34 has an interaction force with the adjusting rod 32 and the mounting rod 31, avoiding the situation where the rotation is restricted only by bolts, thus improving the connection stability. In use, one or more adjusting rods 32 are installed between the mounting rod 31 and the limiting rod 33 through the cooperation of the protrusion 34 and the groove 35, so that the length of the connecting rod 3 can be adjusted to adapt the connecting rod 3 to river channels of different depths.

[0048] In summary, when using this utility model, the mounting plate 4 is installed on the hull, and one or more adjusting rods 32 are installed between the mounting rod 31 and the limiting rod 33 through the cooperation of the protrusion 34 and the groove 35, so that the length of the connecting rod 3 is adjusted to be greater than the water depth. The pipe 1 is moved to the bottom silt by gravity, so that the pipe 1 drives the connecting rod 3 to be tilted in the water by gravity, and the agitator 2 comes into contact with the silt. The position of the agitator 2 is automatically adjusted by the speed of the hull. At the same time, the motor 6 drives the rotating shaft 7 to rotate in the pipe 1, so that the rotating shaft 7 drives the agitator 2 to rotate, agitating the silt and blocking debris. When the agitator 2 rotates, the rotating shaft 7 drives the spiral plate 8 to rotate inside the pipe 1, so that the spiral plate 8 carries the silt water into the pipe 1. The pipe 1 allows the external pump to discharge the silt water to the hull for filtration.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
