Abstract

The present invention relates to a freshwater reservoir in a sea, which comprises a water retaining dam, wherein a water overflow channel (12a) is arranged on the water retaining dam. The present invention is characterized in that a river channel entrance (4) is arranged on the water retaining dam, and water baffling boards (3) are movably distributed on the periphery of the upper end part of the water retaining dam positioned in the sea; the water retaining dam is rectangular and formed by a surrounding of four dams, wherein dams (11, 12, 13) in three directions are built in the surface of the sea, the other dam is an original sea dam (1), and the river channel entrance (4) is positioned on the original sea dam (1). Compared with the prior art, the present invention has the advantages that farmland is not occupied, only dams are built and work of move, blasting, excavation, etc. is not needed, which saves land resource, reduces investment on a vast scale, simplifies construction of reservoirs of super large volume. In addition, compared with traditional dams, the present invention adds a plurality of movable water baffling boards and waterproof clothes which can effectively prevent pollution of water and reduce damage of the sea to people.

Description

Marine fresh water reservoir

Technical field

The present invention relates to a kind of hydraulic engineering technical field, especially refer to a kind of marine fresh water reservoir that is built on the sea.

Background technology

China is that fresh water lacks one of state, and for production and the living water use that solves people, government had made to be determined to develop seawater resources, but was costly after all.On the other hand, we have river, the river of flood tide to enter big Hiroad every year is seawater, become seawater with its fresh water such as grade and extract again, why not before entering the sea, it is stored away? reason is very simple, builds reservoir on land and has not only taken up an area of but also consume huge fund.An existing application number is 99122586.4 and is called that the Chinese invention patent of " method of marine storing fresh water " discloses a kind of method of storing up fresh water at sea, its imagination better, but its shortcoming is just with the fresh water transferring position, and does not fundamentally solve the shortage problem of freshwater resources.Also have a kind of in March, 1997 China Hohai University journal the 25th volume the 2nd phase title " choose reasonable of tidal land reservoir filling position " that has been published in to disclose a kind of structure, its content is: the tidal land reservoir is that fill all around surrounds reservoir on tidal land, the water lift warehouse-in stores from the network of waterways, and earth embankment is the major project of reservoir.Build the tidal land reservoir, retaining fresh water is an effective way that solves the disparities between supply and demand of water.Four kitchen range Pu tidal land reservoirs are positioned at Hangzhou Wan south bank, surround reservoir by mount all around, and reservoir Bei Di faces Hangzhou Wan.But its shortcoming is that only the height of rational position, cost, capacity and dykes and dams is selected in prompting, does not provide the concrete structure that prevents effectively fresh water pollution in the storehouse, so its structure awaits to improve.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of at above-mentioned prior art present situation and do not take cultivated land, need not move and only build dykes and dams and economize the land resource, invest low and can prevent marine fresh water reservoir to fresh water pollution in the storehouse effectively.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this marine fresh water reservoir, include check dam, on check dam, have spillway, described check dam has the river course inlet on it, it is characterized in that being distributed with water baffle versatilely, and in check dam, be provided with continuous canvas cloth in the periphery that is positioned at marine check dam upper end.

As improvement, its profile of described check dam can be preferably square four dykes and dams and surround, and wherein three dykes and dams are built by laying bricks or stones in the sea, and another is former sea dykes, and described river course inlet is positioned on the former sea dykes; In order to play more anti-pollution, described continuous its top of canvas cloth is fixed with the plastic foam piece of floating power effect a little more than the water surface and on the end, its bottom hangs with the weight that canvas cloth is erect near the sea bed position, and has water outlet with the river course inlet on the canvas cloth of one side; This canvas cloth can parallel with being positioned at three marine dykes and dams respectively, and be floated on respectively with the check dam of three dykes and dams away from a segment distance position in.

As further improvement, described spillway is positioned on the dykes and dams relative with the river course inlet, and on the dykes and dams that are positioned at these both sides, spillway bottom, can have emptying gate; And described water baffle can be arc, and the one end is fixed with the plastic foam piece of floating power effect, and the other end is embedded in the base for being arranged at the dykes and dams periphery movably; And the structure that described water baffle is arranged in the base movably can be preferably by the rotating shaft connection, can certainly be that hinge connects, and specifically can decide by specific requirement.And water baffle engagement edge place each other can be provided with the water stopping trough that cooperatively interacts.

Improve again, described check dam may be selected to be ellipse, circle, trapezoidal or polygon, the dykes and dams that can certainly be other shape surround, also can be provided with continuous canvas cloth in the described check dam, the top of canvas cloth is fixed with the plastic foam piece of floating power effect a little more than the water surface and on the end, its bottom hangs with the weight that canvas cloth is erect near the sea bed position, and has water outlet with the river course inlet on the canvas cloth of one side; And the bottom of described check dam also can have emptying gate.

Compared with prior art, the present invention uses because of employing will enter marine fresh water, enters marine entrance in the river course and builds a reservoir, and be distributed with water baffle movably in the periphery that is positioned at marine check dam upper end.The source that the invention has the advantages that water is river, river, rainwater and life sewage, and is just recycling through simple process, and it is secure to originate; And do not take cultivated land, only build dykes and dams and don't need do resettlement, explosion and excavation work etc., not only economize the land resource but also reduced investment significantly, and be easy to build up the reservoir of vast capacity; Also having the present invention to compare with conventional dam has increased mobilizable water baffle of part and dash canvas cloth, and they can prevent seawater effectively to Fresh Water Pollution in the storehouse, and can stop the impact of wave to a certain extent, thereby reduces the harm of wave to people; Have the present invention of being to build because of artificial again, its geographical position and outward appearance can be selected and design on request, and superior geographical location can also be visited for the visitor, and also can culture aquatic product in reservoir as tourism resource with the profile that is designed beautifully like this.So the present invention is a kind of invention very ingenious, utilization is worthy to be popularized.
