[0002] The traditional water conservancy protection slope structure mainly uses a concrete base as the water retaining main body, which is fixed at a certain position to block the water flow at this position. During flood control, the water flow may wash away the water retaining structure, and the water flow flows out from the damaged position, causing damage to the downstream buildings or land.

[0015] With the above technical solution, the beneficial effects of the present utility model are as follows:

[0016] Since the water conservancy protection slope structure includes a sliding frame, during the use of this structure, the support frame can be placed at the position where water needs to be blocked. Then, the first water retaining cylinder is installed on the support frame at a certain distance. Push the second water retaining cylinder on the sliding frame along the Y-axis direction. After the sliding frame is installed on the support frame, each second water retaining cylinder is arranged downstream of the first water retaining cylinder. This can enable the first water retaining cylinder to block the impact of the water flow on the second water retaining cylinder, making the installation of the sliding frame smoother. After the sliding frame is installed on the support frame, push the second water retaining cylinder so that the second water retaining cylinders are all arranged between two adjacent first water retaining cylinders. Driven by the linear drive mechanism, the sliding frame moves towards the direction close to the first water retaining cylinder, so that the second water retaining cylinder blocks most of the water flow between two adjacent first water retaining cylinders. Then, place stones between the first water retaining cylinder and the second water retaining cylinder. At this time, under the action of the stones, the first water retaining cylinder and the second water retaining cylinder, the water flow is blocked. Then, position the first water retaining cylinder and the second water retaining cylinder through the first adjustable mounting plate and the second adjustable mounting plate, and then install the arc-shaped buffer side plates on both sides of this structure, that is, the installation of this structure is completed. In the present invention, both the first water retaining cylinder and the sliding frame are adopted in a detachable manner, so that this structure can be installed more flexibly at the position where water needs to be blocked for flood prevention operations. At the same time, arc-shaped buffer side plates are slidably installed on both sides of this structure. When this structure is impacted by the side water flow, the arc-shaped buffer side plates are deformed by the force, and the mounting rods slide along the sliding grooves. The impact force of the water flow on this structure is released by the deformation of the arc-shaped buffer side plates under the force, increasing the impact resistance of this structure and making this structure more stable.

[0017] In the present invention, the upper end of the first water retaining cylinder is fixedly installed on one of the first support rods through a right-angle folding plate and a positioning plate, and is fixedly installed on the other first support rod through a first fixing plate, a first adjustment groove and a second positioning bolt. The lower end of the first water retaining cylinder limits the weight base at the bottom of the first water retaining cylinder through a limiting groove. The present invention fixes both the upper end and the lower end of the first water retaining cylinder, ensuring the installation flexibility of the first water retaining cylinder while increasing the stability of the first water retaining cylinder.

[0018] In the present invention, both ends of the second water retaining cylinder can be fixed on the sliding frame through a first guide sleeve, a second guide sleeve and a guide sleeve fixing bolt. The sliding frame is fixed to the support frame through a sliding rod fixing bolt. The second water retaining cylinder is also fixed to the support frame through a second fixing plate, a third positioning bolt and a second adjustable mounting plate. The present invention fixes both ends of the second water retaining cylinder, ensuring the installation flexibility of the second water retaining cylinder while increasing the stability of the second water retaining cylinder.
