Self-spinning steel dam with centre rotating shaft

Abstract

The invention discloses a self-spinning steel dam with a centre rotating shaft, and relates to the field of water conservancy and hydropower; the self-spinning steel dam comprises a dam foundation; side walls are poured on the two sides of the dam foundation; a plurality of supporting piers are poured on the top of the dam foundation; the tops of the supporting piers are fixedly connected with pre-embedded steel plates through anchor bolts; foot support shaft sleeves are fixedly connected to the plurality of pre-embedded steel plates; the same rotating main shaft penetrates through the plurality of foot support shaft sleeves; the upper side of the rotating main shaft is fixedly connected with an upper panel; and the lower side of the rotating main shaft is fixedly connected with a lower panel. According to the invention, panel stress is more scientific; a rotating fulcrum of the hydraulic self-rotating dam is located in the middle; mutual offset of upper water pressure and lower water pressure is fully utilized; opening and closing force is greatly reduced; when the hydraulic self-rotating dam is full of water, panel stress is self-balanced; meanwhile, a main shaft can penetrate through a side wall to be provided with a hydraulic pump room; a hydraulic control system and a vertical dam releasing mechanical locking structure are installed in the pump room; and the retaining dam is convenient to maintain, is attractive in appearance and stable in structural design.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower, in particular to a central rotating shaft spinning steel dam. Background technique [0002] In the construction of water conservancy and hydropower, with the needs of urban water use, landscape construction, environmental improvement, irrigation and power generation, flap gates, sluice gates and rubber dams are widely used. However, the production of rubber dams is more complicated, and the water is filled during operation ( It takes a long time to lift the dam by inflating or release water (deflate) to collapse the dam, which affects the rapid closure or flood discharge. In addition, the disadvantage of rubber aging is easy to cause quality accidents. Therefore, a large number of steel structure gates appear on the market now. [0003] The hydraulic steel dam is a kind of steel structure gate. Considering various aspects such as water level characteristics, construction conditions...

[0002] In the construction of water conservancy and hydropower, with the needs of urban water use, landscape construction, environmental improvement, irrigation and power generation, flap gates, sluice gates and rubber dams are widely used. However, the production of rubber dams is more complicated, and the water is filled during operation ( It takes a long time to lift the dam with air or release water (deflate) to collapse the dam, which affects the rapid closure or flood discharge. In addition, the disadvantage of rubber aging is easy to cause quality accidents. Therefore, there are a large number of steel structure gates on the market now.
