Abstract
A hydraulic telescopic dam comprises a dam base (101), a dam body (102) and a hydraulic cylinder (103). The dam base (101) comprises an inclined face (1011), and the dam body (102) and the hydraulic cylinder (103) are arranged along the inclined face (1011); the telescopic end of the hydraulic cylinder (103) is fixed to the top of the dam body (102), and the other end of the hydraulic cylinder (103) is fixed to the dam base (101); and the corresponding positions of the dam body (102) and the inclined face (1011) are provided with a pulley and a sliding groove respectively. The hydraulic cylinder (103) telescopically drives the dam body (102) to vertically slide along the inclined face (1011). Back hydraulic lifting of the dam surface is changed into top hydraulic lifting, the back face of the dam body and the inclined face of the dam base are in pulley rolling so as to reduce friction force, and the hydraulic cylinder is mounted on the top of the dam base, so that maintenance is convenient.
Description
Technical field
The present invention relates to water conservancy projects technical field, especially a kind of hydraulically extensible dam.
Background technology
At present, hydraulic pressure dam progressively replaces rubber dam, shutter dam, is widely used in the fields such as agricultural irrigation, fishery, ship lock, seawater gear tide, city river landscape engineering and Construction of Small Hydropower Station.
Hydraulic pressure dam is primarily of movable dam facing, sliding supporting bar, hydraulic cylinder and hydraulic power unit composition, and the conveniently height of adjustment activity dam facing, arranges multistage limitation locking mechanism usually.The advantage on hydraulic pressure dam is that structure is simple, flexible operation, but the main building block such as hydraulic cylinder is all positioned at bottom absorption basin, and be not easy to maintenance, the cost of overhaul is high.Limitation locking structure is immersed in water is for a long time blocked by silt, or loses limit function, then makes sliding supporting bar lose supporting role; Or be in holding state for a long time, cause dam body to decline.If use hydraulic cylinder to carry out long term support to movable dam facing simple, can form interior leakage between two oil pockets of hydraulic cylinder, this interior leakage can cause dam body to decline.Hydraulic cylinder also needs tight cooperation with limitation locking mechanism, not so can cause the problems such as dam body damage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of stable performance, is easy to the hydraulically extensible dam of maintenance.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of hydraulically extensible dam, comprise the dam foundation, dam body, hydraulic cylinder, the dam foundation comprises inclined plane, and dam body and hydraulic cylinder are arranged along inclined plane; Hydraulic cylinder extension end is fixed on dam body top, and the other end is fixed on the dam foundation; The correspondence position on dam body and inclined plane is equipped with pulley and chute respectively, and hydraulic cylinder extension drives dam body to slide up and down along inclined plane.
The crossbeam of fixer cylinder pressure is arranged at dam foundation top; The ears or side handles of a utensil of connecting fluid cylinder pressure are arranged at dam body top, the ears or side handles of a utensil and dam body one-body molded.
The dam foundation is provided with groove near the side in dam foundation tilting face, and dam body correspondence position is provided with fin, and dam body fin gos deep in dam foundation groove, and the gap adhesive tape between dam body fin and dam foundation groove is sealed.
Dam facing back hydraulic pressure is lifted to fall and is improved to top hydraulic lifting by the present invention, and adopt pulley rolling to reduce friction between the dam body back side and dam foundation tilting face, hydraulic cylinder is arranged on dam foundation upper top, is convenient to safeguard.
