Supporting hydraulic lifting dam

Abstract

The invention discloses a supporting hydraulic lifting dam which comprises a gate plate, a supporting rod device, a hydraulic lifting device, a mounting base, a limit plate, a protection cover and a main control system. One end of the hydraulic lifting device is fixedly connected with the gate plate, the other end of the hydraulic lifting device is fixedly connected with the mounting base, a sliding groove is formed in the upper end of the limit plate, one end of the supporting rod is fixedly connected with the gate plate, the other end of the supporting rod and the sliding groove in the limitplate are used in a matched manner, the limit plate is fixedly mounted at the upper end of the mounting base, one end of the gate plate is fixedly connected with the mounting base through a first hinge device, the protection cover is fixedly mounted at the upper end of the first hinge device, the gate plate is lifted by the aid of a gate plate lifting cylinder, a supporting rod body is laid out by the aid of a supporting rod cylinder, so that an 'inverted V-shaped' support is formed between the supporting rod body and the gate plate, the gate plate lifting cylinder and the supporting rod cylinder can be unloaded, and the lifting dam has the advantages of convenience in use and reliability in supporting.

Description

technical field [0001] The invention relates to a hydraulic lifting dam, in particular to a supporting type hydraulic lifting dam. Background technique [0002] The hydraulic dam is a relatively simple movable dam, which is widely used in the construction of agricultural irrigation, fishery, ship locks, seawater tidal protection, urban river landscape engineering and small hydropower stations. The mechanical structure of the hydraulic lifting dam is scientific, not blocking water, not afraid of mud and sand deposition; not affected by floating objects; in the case of a very small loss of water, it can easily wash away the floating objects upstream, making the river clear; the dam is released quickly, Does not affect flood control safety; strong ability to resist flood impact. The structure of the hydraulic dam is usually composed of an arc or straight gate plate, a gate plate lifting cylinder and a hydraulic pump station. It uses the gate plate lifting cylinder to directly...

AI Technical Summary

Problems solved by technology

In principle, this structure can support the hydraulic dam when the two support rods are in a straight line, but the connection of the first support rod driving the second support rod through the pin shaft is not reliable, and it is prone to instability.

In the entire dam body, as long as a part of the hydraulic dam strut fails, the huge water flow will cause serious personal injury and property loss.

[0003] Traditional hydraulic dams have no water level monitoring function. Generally, manual visual water level scales are used to judge the water level height, and then the opening and closing movable plates are manually controlled, so the working status of the hydraulic dam cannot be adjusted in time according to the current water level.
