An automatic control device for lagoon-type sea area ecological water level

Abstract

The invention discloses an automatic control device for the ecological water level of lagoon type sea areas. The device is characterized in that multiple bidirectional water taking pipes are arranged in a bulwark which separates a landscape area from an open sea, wherein the two sides of each bidirectional water taking pipe communicate with each other; and multiple unidirectional draining pipes are arranged at the positions, below the bidirectional water taking pipes, in the bulwark, wherein the two sides of each unidirectional draining pipe communicate with each other. The multiple bidirectional water taking pipes are horizontally arranged in the bulwark, and the unidirectional draining pipes are obliquely arranged in the bulwark. One downwards-oblique ends of the unidirectional draining pipes communicate with the open sea, and the other downwards-oblique ends of the unidirectional draining pipes communicate with an inland sea. Each unidirectional draining pipe is internally provided with a unidirectional valve. First control valves are arranged at the positions, communicating with the inland sea, on the bidirectional water taking pipes, and second control valves are arranged at the positions, communicating with the inland sea, on the unidirectional draining pipes. The automatic control device for the ecological water level of the lagoon type sea areas has the beneficial effects that the high tide level, the low tide level and the inland sea tidal capacity of the lagoon type sea areas are controlled, and therefore distribution of intertidal zones of the lagoon type water areas can be controlled, the design difficulty and the construction difficulty of artificial beaches and artificial red beaches are lowered, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and water transport engineering, in particular to an automatic control device for lagoon-type sea area ecological water level. Background technique [0002] Panjin Red Beach is located in the northeast of Bohai Bay, in the wetland of Liaohe Delta, Panjin City in Liaohe Delta, and is a famous national nature reserve. Red Beach Scenic Area is a national 4A-level scenic spot and an excellent tourist attraction in Liaoning Province. It is located in Zhaoquanhe Township, Dawa County, Panjin City, Liaoning Province. It belongs to the wetland eco-tourism scenic spot. It is based on the best preserved and largest wetland resources in the world, relying on the rare red beach in the world and the largest reed marsh in the world. It is a perfect combination of natural environment and cultural landscape. It is a comprehensive green eco-tourism scenic spot integrating tourism, sightseeing, leisure ...

AI Technical Summary

Problems solved by technology

The design of the artificial beach encounters the following problems: A. Affected by the wind, wave and tide level, the unsheltered artificial beach is easily polluted by muddy sand

B. Changes in tidal levels within a year lead to a large range of changes in the intertidal zone. To achieve a better landscape effect, it is necessary to spread sand in a larger range, resulting in waste
