Problems solved by technology

Obviously, when the water retaining height of the existing hydraulically driven landscape hinge movable dam is high, the load of the hydraulic system is relatively large, the piston rod of the hydraulic cylinder protrudes longer, and the stability is poor, especially when the water retaining height of the dam is high. When the hydraulic cylinder is impacted by the dam body and the water flow, it needs to bear a large locking force to prevent the dam body from moving, which will lead to the risk of collapse of the hydraulic system

Embodiment Construction

[0056] The present application will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0057] Such as Figure 1-9 As shown, the embodiment of the present application provides a landscape hinge movable dam, including a dam body 10, a base 20, a tie rod 30, a support 40, a hydraulic cylinder 50, and a locking structure 60. The base 20 can be fixed to the foundation, such as by Anchor screws are fixed to the foundation. The dam body 10 is connected to the base 20 around the first rotating shaft, the supporting member 40 is rotating around the second rotating shaft, and one end of the hydraulic cylinder 50 is respectively connected to the base 20 around the third rotating shaft; The fifth rotating shaft is rotatably connected to the dam body 10 ; the other end of the hydraulic cylinder 50 is rotatably connected to the pull rod 30 around the sixth rotating shaft. One end of the locking structure 60 is rotatably c...

Abstract

The invention relates to the technical field of dams, in particular to a landscape hinge movable dam. The landscape hinge movable dam comprises a dam body, a base, pull rods, supporting pieces, hydraulic cylinders and locking structures. The dam body is rotationally connected to the base around a first rotation shaft. Each supporting piece is rotationally connected to the base around a second rotation shaft. One end of each hydraulic cylinder is rotationally connected to the base around a third rotation shaft. One end of each pull rod is rotationally connected to the corresponding supporting piece through a fourth rotation shaft, and the other end of each pull rod is rotationally connected to the dam body around a fifth rotation shaft. The other end of each hydraulic cylinder is rotationally connected to the corresponding pull rod around a sixth rotation shaft. One end of each locking structure is rotationally connected to the corresponding supporting piece through a seventh rotation shaft, and the other end of each locking structure is provided with a locking groove. Each supporting piece is provided with a track. Each hydraulic cylinder is provided with a sliding block. The sliding blocks can move along the corresponding tracks and can move into the corresponding locking grooves. According to the landscape hinge movable dam, the overall stability and the flood prevention ability of the movable dam are improved; and damage of the hydraulic cylinders due to dam locking water blockage can be prevented.

Description

technical field [0001] The application relates to the technical field of dams, in particular to a landscape hinge movable dam. Background technique [0002] The hydraulically driven landscape hinge movable dam is a low-head water-retaining structure, and a hydraulic cylinder is often used to directly drive the dam body, that is, one end of the hydraulic cylinder is connected to the dam body, and the other end is connected to the foundation. Obviously, when the water retaining height of the existing hydraulically driven landscape hinge movable dam is high, the load of the hydraulic system is relatively large, the piston rod of the hydraulic cylinder protrudes longer, and the stability is poor, especially when the water retaining height of the dam is high. At this time, the hydraulic cylinder needs to bear a large locking force due to the impact of the dam body and the water flow to prevent the dam body from moving, which will lead to the risk of collapse of the hydraulic syst...
