Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a protective structure for a slope of a hydropower and water conservancy project. Background Art

[0002] The slopes of hydropower and water conservancy projects are usually protected by cement blankets. The cement blankets form a high-strength protective layer with both waterproofing and soil-fixing functions. Flood walls are usually built under the cement blanket protection structure next to the river. Although flood walls can effectively block river water, they also have certain shortcomings. That is, because the flood walls are set high, pedestrians will feel a greater sense of oppression when walking next to the flood walls. At the same time, the flood walls will also obstruct pedestrians' vision, making it impossible for them to appreciate the river scenery. Furthermore, the construction cost of flood walls is high and the construction period is long. Summary of the Invention

[0003] The purpose of the present invention is to provide a protective structure for the slope of a hydropower and water conservancy project to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A protective structure for a slope of a hydropower and water conservancy project, comprising a cement protective plate, a walkway fixedly provided on the lower side of the cement protective plate, a water collection channel provided on the walkway, and drainage channels connected at both ends of the water collection channel;

[0006] The walkway is equipped with a movable water retaining assembly, which moves upward synchronously to block the river water when the water level in the river rises;

[0007] The movable water retaining assembly is connected to a water retaining assembly auxiliary support mechanism, and the movable water retaining assembly drives the auxiliary support mechanism to move, and the auxiliary support mechanism provides auxiliary support for the movable water retaining assembly;

[0008] The walkway is also provided with a two-way sealing assembly, which contacts the walkway and the movable water retaining assembly respectively to seal the connection;

[0009] The bidirectional sealing assembly is provided with a blocking mechanism, and the auxiliary supporting mechanism of the water retaining assembly drives the blocking mechanism to move, thereby fixing the bidirectional sealing assembly and blocking the drainage channel at the same time.

[0010] Preferably, the movable water retaining assembly is a movable water retaining plate, on which an inclined buoyancy plate is fixedly provided, the movable water retaining plate is partially inserted into the river water, and the inclined buoyancy plate floats on the water surface.

[0011] Preferably, the auxiliary support mechanism of the water retaining assembly includes a matching support block, a pushing support bar, a movable support column, a movable support block and a movable reinforcing plate. The matching support block is connected to the movable water retaining plate, and the movable water retaining plate drives the matching support block to move synchronously.

[0012] Preferably, the push carrier bar is installed on the matching bearing block, and when the matching bearing block moves, the push carrier bar is driven to move.

[0013] Preferably, a movable bearing column is symmetrically hinged on the mating bearing block, and a movable bearing block is hinged at the lower end of the movable bearing column, and the movable bearing column drives the movable bearing block to move.

[0014] Preferably, the movable reinforcing plate is installed on a movable bearing column, and the pushing bar is connected to the movable reinforcing plate to drive the movable reinforcing plate to move.

[0015] Preferably, a reinforcing contact plate is movably provided on the movable reinforcing plate, and the movable water baffle is auxiliary supported by the reinforcing contact plate in contact with the movable water baffle.

[0016] Preferably, the bidirectional sealing component is a load-bearing bar frame, and a sealing matching sleeve is provided on the periphery of the load-bearing bar frame. The lower side of the sealing matching sleeve contacts the walkway, and the side of the sealing matching sleeve close to the movable water baffle contacts the movable water baffle.

[0017] Preferably, the blocking mechanism includes a first movable bearing block and a blocking bearing bar, the first movable bearing block is movably installed in the bearing bar frame, and the bearing bar frame is fixed by the first movable bearing block.

[0018] Preferably, blocking plates are symmetrically fixedly provided on the blocking bearing bars, and the drainage channel is blocked by the blocking plates.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. A movable water retaining plate is provided on the lower side of the cement protective plate. When the water level of the river does not rise, the movable water retaining plate is in a lower position, which will not cause a greater sense of oppression to pedestrians and will not affect pedestrians' appreciation of the river scenery. When the water level of the river rises, the movable water retaining plate will rise according to the rise in the water level and thus can play a role in blocking the water. It is easy to lay, low in cost, short in construction period, easy to install and dismantle, and easy to maintain.

[0021] 2. When the river water level rises, the inclined floating force plate will move up with the rising of the water level because it floats on the water surface, and then it can drive the movable water baffle to move up to block the river water, at the same time, the movable water baffle will drive the matched bearing block to move, and then it can drive the movable bearing column to move, the movement of the movable bearing column will make the movable reinforcing plate move to the direction of the movable water baffle, so that the reinforcing contact plate will contact with the movable water baffle when the water level rises to a certain degree, which can support the movable water baffle and further strengthen its bearing strength to better block the water.

[0022] 3. In addition, the movement of the movable bearing column will also drive the movement of the movable bearing block, and then under the action of the movable bearing block, the first movable bearing block will be moved to be sleeved on the limiting insertion bar to fix the bearing strip frame and ensure the sealing between the bearing strip frame and the cement protection plate, at the same time, the movement of the first movable bearing block will make the sealing bearing strip move down under the action of its own gravity, and then it can seal the drainage channel under the action of the sealing insertion plate to avoid the reverse movement of the river water from the drainage channel to the cement protection plate when the river water level rises.
