Abstract

The invention provides a tide sand protection dike, and belongs to the field of tidal power generation. The tide sand protection dike is composed of a pile foundation, a stand column, an anchor cable, gate openings, gates, a floating body and the like. The gates are divided into the water inlet gate, the sand blocking gate and the sand flushing gate according to the different functions of the gates, so that mud and sand in a reservoir can come out, and mud and sand outside the reservoir can not come in. According to the design requirement, all the needed parts are made of weather-proof and bittern-resistance manganese and vanadium alloy steel, abrasion-resistant, impact-resistant and anti-ageing high polymer materials are used as a protecting layer, and the influence on the service life of underwater parts of sea phagocytosis is lightened.

Description

Morning and evening tides sand-protecting dam

Technical field:

The invention belongs to tidal power generation field, be specifically related to a kind of morning and evening tides sand-protecting dam.

Background technology:

Oceanic tide is being contained huge clean reproducible energy, as far back as 1970, and China's First tidal power station, Rushan, Shandong Province white sand mouth tidal power station just starts to start building, lasted completion in 27 years to 1987, due to silt silting, storage capacity atrophy, bite seriously in submarine mechanical parts sea, this power station is out of service in 1989, although application life is of short duration, but the social benefit index of the output value that it is earned and realization, more than 20 times that invest in power station itself, the present invention is directed to silt silting and submarine mechanical sea and bite serious this two large outstanding problem, according to oceanic tide feature and ocean water environment, on the bases such as my original invention " rolling curtain type sluice gate " " non-batardeau concrete dam construction method " " automatic open and close lock " and " steel frame dam ", comprehensively improve.

Summary of the invention:

The invention provides a kind of morning and evening tides sand-protecting dam, belong to tidal power generation field, it is characterized in that: required each parts are according to designing requirement, select manganese vanadium alloy steel weather-proof, salt tolerant halogen to do, taking wear-resisting, shock resistance, aging-resistant macromolecular material as overcoat, specifically comprise pile foundation 1, column 2, anchor cable 3, water inlet sluice gate 4, inlet gate 5, sand prevention sluice gate 6, sediment trapping gate 7, scouring sluice 8, open the parts such as lock draw ring 9, buoyancy aid 10.Column 2 and anchor cable 3 are installed in its pile foundation 1, with anchor cable 3 vertical columns 2, between each adjacent upright posts, be installed into sluice mouth 4, inside-of-refrigerator at water inlet sluice gate 4 is installed the inlet gate 5 with hydraulic pressure automatic open and close, the husky sluice gate 6 of setting up defences below water inlet sluice gate 4, in the off-lying sea of sand prevention sluice gate 6 side, the sediment trapping gate 7 with hydraulic pressure automatic open and close is installed, inside-of-refrigerator at sand prevention sluice gate 6 is installed the scouring sluice 8 with buoyancy automatic open and close, the lock draw ring 9 that opens of scouring sluice 8 lower ends is connected with buoyancy aid 10 by anchor cable 3, its inlet gate 5, sediment trapping gate 7, scouring sluice 8 is curtain-type sluice gate, to organize rigid section 12 by bolt 11 is fixed on flexible substrate 13 and forms more.High tide higher than in storehouse when water level, inlet gate 5 is automatically opened under Water Pressure, seawater pours in storehouse by water inlet sluice gate 4, meanwhile, sediment trapping gate 7 is automatically closed under Water Pressure, prevent that bottom seawater from sweeping along silt to enter in storehouse, when water level in storehouse is during higher than established standards, scouring sluice 8 is automatically opened under buoyancy, at ebb tide, in storehouse, water level is higher than outside storehouse, inlet gate 5 is automatically closed retaining under Water Pressure, sediment trapping gate 7 is automatically opened under Water Pressure, the water yield more than needed is washed away away silt in storehouse by scouring sluice 8 and sediment trapping gate 7 from sand prevention sluice gate 6, thereby effectively prevent silt silting

Fig. 2 is curtain-type sluice gate,

Fig. 3 is sand-protecting dam schematic diagram

Detailed description of the invention: Fig. 1 is morning and evening tides sand-protecting dam, first: by required each parts according to designing requirement, with weather-proof, the manganese vanadium alloy steel of salt tolerant halogen is done, with wear-resisting, shock resistance, aging-resistant macromolecular material is overcoat, after making adequate preparation, implant pile foundation 1 in corresponding marine site, column 2 and anchor cable 3 are installed in pile foundation 1, with anchor cable 3 vertical columns 2, between each adjacent upright posts 2, be installed into sluice mouth 4 and sand prevention sluice gate 6, to organize firm section bar 12 with bolt 11 is fixed on flexible substrate 13 more, composition inlet gate 5, sediment trapping gate 7 and the required curtain-type sluice gate of scouring sluice 8, inlet gate 5 is installed on into the inside-of-refrigerator of water sluice gate 4, sediment trapping gate 7 is installed on to the off-lying sea side of sand prevention sluice gate 6, scouring sluice 8 is installed on to the inside-of-refrigerator of sand prevention sluice gate 6, the lock draw ring 9 that opens of scouring sluice 8 lower ends is connected with buoyancy aid 10 by anchor cable 3, by adjusting draw ring 9 and buoyancy aid 10, the length of anchor cable 3 between buoyancy aid 10 and pile foundation 1, set the control water level of scouring sluice 8.
