Problems solved by technology
However, the problems in this case are: first, it only has a one-way function; second, its action depends on the presence of water in the tank. If it is in an arid area, it is difficult to ensure that there is water in the tank. How to solve the problem of water in the tank? It has become the main problem restricting its use in arid areas; the third is the problem of water sealing. When there is a drop in the upstream and downstream water levels, this kind of flap gate cannot solve the problem of water sealing only by relying on rubber sealing strips; the fourth is the sedimentation in the tank The problem is difficult to solve, resulting in the gate not sinking to the bottom, affecting flood discharge, and in severe cases, it may lead to heavy losses of personnel and property

Abstract
The invention discloses a bidirectional hidden air shield dam, and relates to water level control gate dams of irrigation channels, ecology landscape river channels and drainage river channels, in particular to an improvement of an air shield dam drive structure. The bidirectional hidden air shield dam which is not provided with an underwater metal drive component and does not depend on water storage driving is provided. The bidirectional hidden air shield dam includes side walls, a dam base, a shield plate structure and a drive air bag, wherein the side walls are arranged on the two shores ofa river channel, the dam base is embedded in the bottom face of the river channel, the shield plate structure is hinged to the dam base, and the drive air bag is used for driving the shield plate structure; the shield plate structure includes an arc shield plate and a truss structure which is located on the back face of the arc shield plate, the cross section of the whole shield plate structure is a fan-shaped cylinder, and an inflation side seal air bag is formed between a guide plate and the arc board face of the shield plate structure. The bidirectional hidden air shield dam can be widelyapplied to water-deficient areas for water resource adjustment, water-abundant areas for discharging flood and urban sites with water adjustment and landscape effects.
Description
technical field [0001] The invention relates to water level control gates and dams for irrigation canals, ecological landscape rivers and flood discharge rivers, in particular to the improvement of the driving structure of the air shield dam. Background technique [0002] Gates and dams are generally used for water retaining control of channels and river courses. For different applications, the requirements for gates and dams are different. As a fixed structure, the dam needs to be combined with the gate to control and adjust the water level. However, there are also small dam structures that have a certain water level adjustment function, such as rubber dams, air shield dams, etc. However, most fixed dams require gates for water level regulation. [0003] The following patented technologies are available in the prior art: [0004] For example, "A Hidden Arc Gate, 2016101776042, 2016-03-25" disclosed by the State Intellectual Property Office provides a hidden arc gate for...
