Description

Technical Field

[0001] The utility model relates to the technical field of dam protection, in particular to an anti-collision protection structure of a dam used in a water conservancy project. Background Art

[0002] In water conservancy projects, dams are one of the common water conservancy construction facilities. At present, the existing dams are generally not equipped with a special structure to buffer the impact of water waves in the dam, resulting in the water waves in the dam directly hitting the dam, and the dam has to bear all the impact of the water waves in the dam. This makes the dam easy to be damaged, which directly reduces the service life of the dam.

[0003] Here, in order to provide certain protection for the dam and effectively extend the service life of the dam, we propose an anti-collision protection structure for the dam for water conservancy projects. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a dam anti-collision protection structure for water conservancy projects, which, when in use, can effectively block and buffer the impact of water waves in the dam, thereby effectively extending the service life of the dam.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A dam anti-collision protection structure for a water conservancy project comprises a dam, including:

[0007] The impact plate has a limited groove pit reserved on the dam, and the impact plate is movably arranged in the limited groove pit, and the impact surface extends to the outside of the limited groove pit;

[0008] A mounting plate is installed and fixed on the inner bottom of the limiting groove pit;

[0009] The buffer structure includes a spring steel plate, a spring and a damper; the two ends of the spring steel plate, the spring and the damper are respectively fixedly connected to the collision plate and the mounting plate, the damper passes through the inner side of the spring, the spring steel plate is located on the outer side of the spring, and multiple spring steel plates are evenly arranged along the circumference of the spring; multiple buffer structures are evenly arranged along the left and right directions.

[0010] As an improvement, the collision surface of the collision plate is an arc-shaped surface, and the bottom end of the arc-shaped surface is tangent to the vertical surface, so that when the water waves in the dam collide with the collision plate, they can be better drained by the arc-shaped surface.

[0011] As an improvement, the spring steel plate is a U-shaped plate structure, and the middle part forms an arc plate structure that is concave inward, and the connection between the middle plate and the side plate of the spring steel plate forms a rounded corner, so that the spring steel plate can effectively buffer the impact force of water waves in the dam.

[0012] The advantages of the utility model compared with the prior art are:

[0013] When the utility model is in use, most of the water waves in the dam will directly collide with the collision plate, and the design of the curved surface will effectively drain the water waves, so that the impact force of the water waves will not completely act on the collision plate, and then through the design of the spring and the spring steel plate, the impact force on the collision plate can be effectively buffered, thereby greatly reducing the impact of the water waves on the dam, allowing very little water wave impact force to act on the dam, effectively protecting the dam, and extending the service life of the dam.
