Lifting wharf capable of automatically adapting to tide level

Abstract

The invention provides a lifting wharf capable of automatically adapting to the tide level. The lifting wharf comprises a fixed platform, a lifting platform and a water level self-adaption mechanism, and positioning holes are formed along the slope of the fixed platform at interval; a through hole is formed in the slope face of the lifting platform, and a limiting column is arranged in the through hole and connected with a lifting control mechanism; the water level self-adaption mechanism comprises a box body and a controller, a longitudinal partition plate is arranged in a cavity of the box body and divides the cavity into a first cavity body and a second cavity body, and water permeable holes are formed in the side wall of the first cavity body; partition plates are arranged in the second cavity body, the second cavity body is divided into a plurality of second sub-cavities, a cavity plate is further arranged in each second sub-cavity, and a gap is formed between the cavity plates and the corresponding partition plates; a floating block is arranged in each second sub-cavity; a through hole is formed in the longitudinal partition plate and communicates with the first cavity body and each second sub-cavity; and the controller is used for controlling the lifting control mechanism to work according to the air pressure value of the second sub-cavities. The lifting wharf can judge the water level change trend according to the change of air pressure in the box body, and self-adaptive water level adjustment of the lifting platform is achieved through an electric control mechanism.

Description

technical field [0001] The invention relates to the technical field of port devices, in particular to an elevating wharf that automatically adapts to tide levels. Background technique [0002] Wharves should be used to aid in disembarkation. [0003] Affected by natural conditions, the tide level of sea water is constantly changing. During the process of high or low water level changes, the wharf will be submerged and its normal use will be affected. [0004] In the prior art, the wharf is usually fixedly arranged beside the shore foundation. This form of pier may render it unusable at high or low tide. There are also wharves with lifting functions, usually by combining purely mechanical adjustment structures to adjust the height of the wharf to adapt to changes in tidal levels. On the one hand, this structure cannot follow the tide level changes in time and accurately, on the other hand, it is easily affected by instantaneous large waves, and responds to instantaneous ch...
