DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: a desilting device for water conservancy and hydropower construction, comprising: a silt extraction pipe 1, a vehicle-mounted mechanical arm connection seat 2, an algae winding drum 3 and a rotating driving drum 4;

[0028] A vehicle-mounted mechanical arm connection seat 2 is sleeved on the side of the silt extraction pipe 1, and the vehicle-mounted mechanical arm connection seat 2 is used to connect with the vehicle-mounted mechanical arm, and the activity of the entire silt removal device is controlled by the vehicle-mounted mechanical arm;

[0029] A main shaft 12 is provided in the silt extraction pipe 1. A spiral blade 121 is welded on the surface of the main shaft 12 located in the silt extraction pipe 1. The rotation of the main shaft 12 drives the spiral blade 121 to rotate, and the silt in the river channel is extracted by cooperating with the silt extraction pipe 1. A silt discharge pipe 11 is connected to the upper side of the silt extraction pipe 1 to send out the extracted silt.

[0030] A power output box 21 is provided in the vehicle-mounted mechanical arm connection seat 2. The power output box 21 includes a servo motor, a speed regulating gear set and a clutch. The power output box 21 drives and connects the main shaft 12 to realize the driving of the main shaft 12.

[0031] The outer side of the lower part of the silt extraction pipe 1 is rotatably connected to the rotating driving drum 4 through a bearing, and the outer side of the rotating driving drum 4 is rotatably connected to the algae winding drum 3 through a bearing. A circle of conical gear ring 41 is integrally provided on the outer surface of the upper part of the rotating driving drum 4. The conical gear ring 41 is transmission-connected to the power output box 21, so that the rotation of the main shaft 12 is realized, and the rotating driving drum 4 is driven to rotate at the same time;

[0032] The clutch of the power output box 21 can control the synchronous and asynchronous rotation of the main shaft 12 and the rotating drive drum 4;

[0033] A hook-claw telescopic track assembly 5 is provided between the rotating driving drum 4 and the algae winding drum 3;

[0034] The hook claw telescopic track assembly 5 comprises a connecting seat 52 and a track 51. The connecting seat 52 and the track 51 are connected end to end and are provided with four groups. The connecting seat 52 is welded to the surface of the rotating driving drum 4. A plurality of tracks 51 are welded in parallel on the connecting seat 52. The track 51 is designed as a centrifugal arc. One end of the track 51 is close to the rotating driving drum 4, and the other end of the track 51 is close to the algae winding drum 3. The track 51 is slidably connected to the waterweed hook 6.

[0035] Specifically, the tail end of the waterweed hook 6 is fixedly connected to the limiting pulley 62, and the limiting pulley 62 is fixedly welded on the connecting rod 61. The connecting rod 61 keeps the limiting pulley 62 synchronous, so that the waterweed hook 6 moves synchronously. The limiting pulley 62 is slidably connected to the track 51, and the waterweed hook 6 slides through the waterweed winding drum 3;

[0036] When the rotary drive drum 4 rotates clockwise, the track 51 moves clockwise with the axis of the rotary drive drum 4. Due to the centrifugal design of the track 51, the limiting pulley 62 gradually deviates against the waterweed hook 6, so that the waterweed hook 6 extends from the surface of the waterweed winding drum 3 to hook waterweed, algae and other plants.

[0037] When the track 51 slides to the maximum distance relative to the waterweed hook 6, the rotary drive roller 4 continues to rotate, so that the waterweed winding roller 3 rotates in the same direction, and the waterweed and algae and other aquatic plants are wound around the surface of the waterweed winding roller 3 to prevent them from falling off;

[0038] When enough plants are wound around, the rotary drive roller 4 rotates in the opposite direction, and the waterweed hook claw 6 retracts along the track 51, so that the waterweed and algae can be smoothly removed from the algae winding roller 3;

[0039] A baffle 31 is integrally provided at the upper end of the algae winding drum 3 to block the waterweed and algae and prevent them from winding to other positions of the device.

[0040] Working principle: The entire silting device is controlled to reach the designated silting position through the vehicle-mounted mechanical arm connection, and the power output box 21 is turned on to drive the main shaft 12 and the rotating driving drum 4 to rotate. The main shaft 12 extracts silt through the cooperation of the spiral blade 121 and the silt extraction pipe 1. At the same time, the rotating driving drum 4 pushes out the water grass hook 6 through the cooperation of the hook claw telescopic track assembly 5, hooks the water grass and algae and wraps them on the surface of the algae winding drum 3;

[0041] When the amount of waterweed and algae on the surface of the algae winding drum 3 reaches a certain amount, the rotary drive drum 4 can be controlled to rotate in the opposite direction to achieve the retraction of the waterweed hook 6, so as to smoothly remove the waterweed and algae on the surface of the algae winding drum 3;

[0042] In the dredging work of water conservancy and hydropower construction, it is convenient to clean aquatic plants and algae, with diversified functions and stronger applicability.
