Movable dam with buffering protection function

Abstract

The invention discloses a movable dam with a buffering protection function, and relates to the technical field of movable dams. According to the movable dam, a protection mechanism comprises a first movable groove, a second movable groove and a supporting spring, wherein the first movable groove and the second movable groove are both formed in the other side of a movable dam body, a first movable plate is slidably connected into the first movable groove, and one side of the first movable plate is fixedly connected with a first supporting rod. According to the movable dam with the buffer protection function, when water flow collides with the first movable plate and a second movable plate, most impact force is transmitted to a concrete base through the supporting plate, so that the stress effect of a lifting oil cylinder is relieved, and the problems that during water storage of an existing movable dam, water in a river collides with the movable dam, when water collides with the movable dam, the collision force can be directly transmitted to an electric oil cylinder, the electric oil cylinder can be damaged after a long time, and therefore normal use of the movable dam is affected are solved.

Description

technical field [0001] The invention relates to the technical field of movable dams, in particular to a movable dam with a buffer protection function. Background technique [0002] The movable dam is a hydraulic structure that can lift the dam body and has the functions of water storage and flood discharge. Dams can be divided into fixed dams and movable dams according to whether the dam body can move. The water conservancy landscape movable dam is a new type of low-head dam. After years of practice, it has become the most advanced movable dam in the water conservancy industry. It has a wide range of applications, such as irrigation in water areas, restoration of groundwater levels in water storage areas, and winter water storage in cold and frozen areas. It is a major invention of water conservancy technology. [0003] During the water storage of the existing movable dam, the water in the river will impact the movable dam, and an electric cylinder is installed between the...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a movable dam with a buffer protection function, which solves the problem that during the water storage of the existing movable dam, the water in the river will hit the movable dam, and when the water hits the movable dam, , the impact force will be directly transmitted to the electric cylinder, which will cause damage to the electric cylinder after a long time, thus affecting the normal use of the movable dam
