Gate type breakwater with adjustable angle

Abstract

The invention relates to a gate type breakwater with the adjustable angle. Under the small-wave sea condition, a worker slowly puts a first gate with holes in seawater along a first upper rail and a first lower rail, at the moment, the breakwater is in the semi-opening state which is equivalent to a semi-transparent embankment, water flow can freely flow in the holes, the influence on a tidal field is small, and therefore sediment deposition in a harbor can be reduced. In addition, some small waves can be blocked, the influence of the small waves on ship navigation and berthing in the harbor can be reduced, when sea waves are quite small, the worker starts a motor to lift the first gate with the holes, at the moment, the breakwater is in the opening state which is equivalent to a transparent embankment, the influence on the motion of the tidal field and the motion of sediment is small, normal flowing of water flow in the harbor can be kept, sediment deposition is reduced, and the inner portion of the harbor can be kept clean.

Description

technical field [0001] The invention relates to a port hydraulic structure, in particular to an angle-adjustable gate type breakwater. Background technique [0002] The breakwater is an important port hydraulic structure. Its function is to maintain the calm water surface in the port and prevent waves from invading the port or coast, so that ships can berth and operate safely. The breakwater can also play a role in preventing the siltation of the harbor basin and the erosion of the shoreline by waves. It is an important part of artificially sheltered coastal ports. [0003] However, existing breakwaters cannot take into account the above functions. Breakwaters with good anti-wave effects often cause serious siltation in the port, making the water depth in the port shallower and affecting the use of the port; breakwaters that can effectively prevent silting are often unable to withstand large waves The attack caused damage to the buildings in the port. Therefore, it is an ...
