[0011] Preferably, the two sides of the impact-resistant plate are ten centimeters away from one end where the two channels are close to each other, so that water can flow from the gap between the impact-resistant plate and the channel to the gate assembly, thereby reducing the impact force of the water flow on the gate assembly.

[0012] Compared with the related art, the utility model provides a water conservancy opening and closing gate for water conservancy project construction, which has the following advantages:

[0013] Beneficial effects:

[0014] 1. The utility model provides a water conservancy opening and closing gate for water conservancy project construction. The installation body is placed in a first slot body, and then the gate assembly is installed in the installation body. The first installation block is first installed on the outer wall of the first guide column, and then the second installation block is installed on the outer wall of the first guide column. When water flow impact occurs in the channel, the water flow will impact the anti-impact plate, and the anti-impact plate will be pushed toward the movable plate by the water flow. The movable plate will be compressed by the pressure, and the damper will expand and contract to absorb energy to achieve buffering, thereby reducing the impact force of the water body on the gate assembly.

[0015] 2. When the anti-impact plate is impacted by water flow, the second mounting block will move along the outer wall of the first guide column, which is conducive to the stable movement of the anti-impact plate. By setting the second spring, when the anti-impact plate needs to be moved out of the outer wall of the first guide column, the anti-impact plate is pressed toward the gate assembly, so that the second spring is compressed in the pop-up assembly, and then the pressure is removed. The rebound force of the second spring can quickly pop out the anti-impact plate, thereby facilitating the rapid removal of the anti-impact plate;

[0016] 3. After placing the bottom end of the first limit block on the inner wall of the bottom end of the third slot body, the third mounting block is placed on the inner wall of the fourth slot body. In this way, after the second spring is rebounded by the buffer assembly, the first limit block will be blocked by the third mounting block, and will always move in the space formed by the third slot body and the third mounting block, thereby improving the water blocking ability.
