[0002] Water conservancy projects are important infrastructure for the development of the national economy, and they play an irreplaceable role in ensuring water supply, flood prevention and disaster reduction, and improving the ecological environment. However, with the influence of long-term operation and the natural environment, waterways in water conservancy projects often accumulate a lot of silt and sediment, leading to problems such as poor water flow, reduced water storage capacity, and deterioration of water quality. Therefore, regular dredging has become an important part of water conservancy project maintenance. However, existing dredging devices are often complex in structure and expensive, especially in small waterways. There are many limitations, and technical innovation and optimization are urgently needed.

[0003] Technical defects of existing dredging devices: Many existing dredging devices are complex in design and contain a large number of mechanical components and control systems, which makes their deployment and operation on small waterways difficult. These devices not only require professional technicians to operate and maintain, but also take up a large space, which is not conducive to use in small waterways with narrow or complex terrain. Therefore, a new type of dredging device for water conservancy projects is urgently needed to provide an effective solution to the defects of existing technologies. Utility Model Content

When the debris moves to the guide plate position, it is retained on the guide plate and cut under the action of the strip blades. The guide plate is inclined with a low front and a high rear so that the debris retained on the guide plate can be discharged from the front. In order to improve the applicability of the utility model in actual use, solar photovoltaic panels can be used to provide electrical energy for the motor.

DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1: Please refer to Figures 1 to 3 A silt removal device for a water conservancy project comprises a rotating blade group 4 and a guide plate 5. The rotating blade group 4 is arranged in multiple groups and fixedly mounted on a rotating shaft 3. The rotating shaft 3 is rotatably mounted with the top of a rotating shaft bracket 2. The rotating shaft 3 is driven to rotate by a motor 1. The rotating blade group 4 is evenly distributed on the rotating shaft 3. The guide plate 5 is arranged on the right side of the rotating shaft 3. A plurality of air-avoiding knife grooves 6 are evenly distributed on the guide plate 5. The air-avoiding knife grooves 6 are used to avoid the rotating blade group 4. The guide plate 5 is tilted with a low front and a high rear.

[0024] The rotating blade assembly 4 includes a plurality of strip blades 10 distributed radially, and the ends of the strip blades 10 are provided with barbs 15 .

[0025] The cutting edge of the strip blade 10 is configured to be sawtooth-shaped.

[0026] Working principle of this embodiment:

[0027] This embodiment can be installed in a narrow waterway to salvage debris flowing through the waterway, thereby preventing the waterway from clogging. When the motor 1 is started, the shaft 3 is driven to rotate through the transmission device, and the multiple rotating blade groups 4 installed on the shaft also rotate accordingly. Each rotating blade group 4 includes a plurality of strip blades 10 distributed radially, and a hook barb 15 at the end of the strip blade 10. The strip blades 10 arranged in parallel during the rotation process salvage debris from the bottom of the waterway. When the debris moves to the position of the guide plate 5, it is retained on the guide plate 5 and cut under the action of the strip blade 10. The equidistantly distributed air-avoiding knife grooves 6 on the guide plate 5 ensure that the rotating blade group 4 can pass smoothly during the rotation process. The guide plate 5 is tilted with a low front and a high rear, so that the debris retained on the guide plate 5 can be exported from the front end. The cutting edges of these blades 10 are designed to be serrated, which can improve the adhesion to the debris. In actual use, in order to improve the applicability of this embodiment, a solar photovoltaic panel can be used to provide electrical energy for the motor 1.

[0028] This embodiment is suitable for installation in narrow waterways of various terrains. It prevents clogging of the waterway by automatically salvaging debris flowing through the waterway. It has a simple structure, low cost and is easy to promote.

[0030] A push plate 9 is slidably mounted between the baffles 7 on the left and right sides.

[0031] A pair of wheel frames 11 are respectively provided at the left and right ends of the front and rear side walls of the push plate 9 , and rollers 12 are rotatably connected to the wheel frames 11 , and the circumferential outer surfaces of the rollers 12 abut against the inner side walls of the baffle 7 .

[0032] A push rod hinge seat 13 is provided at the rear side of the push plate 9 , and a push plate rod 14 is hingedly connected to the push rod hinge seat 13 .

[0033] In this embodiment, the limit plate 8 can prevent debris from moving from the left and right sides of the guide plate 5. When debris is trapped on the guide plate 5, the maintenance personnel can manually push the push plate 9 to remove the debris. The roller 12 can improve the smoothness of the push plate 9 to avoid jamming, and the push plate rod 14 facilitates manual pushing of the push plate 9.
