3. The utility model discloses the accessible sets up the check gate control flow, can provide the view water level for middle and small river, improves the peripheral water environment of river, resumes the river ecology.

4. The utility model discloses promote and improve river quality of water for the economic value in river both sides land used increases, promotes the faster development of surrounding city social economy.

5. The utility model discloses not only have the effect of guarantee river quality of water, the regulation lake ecological landscape is made to the accessible moreover, provides the condition of hydrophilic paddling for the visitor, promotes the development of local tourism economy.

6. The utility model discloses under the condition of guaranteeing river water flow, the regulation lake can provide peripheral agricultural irrigation water, and the effect of lake irrigation is regulated and stored in the performance.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the following description of the preferred embodiments of the present invention is given with reference to the accompanying examples, but it should be understood that the drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

As shown in fig. 1, a certain amount of internal lakes or newly-built artificial lakes are selected as a regulation lake 1 of a water quality assurance system at the upstream of a plain river network, a large lake 2 and the regulation lake 1 are connected through a water intake runner 3 (tunnel or pipeline) having a certain slope, and the large lake 2 and the regulation lake 1 are connected together through the plain river network arranged at the periphery, so that a circulating flow of river water and lake water is formed in the river network. Wherein the plain river network is a plurality of rivers (river one to river eight) connecting the large lake 2 and/or the regulation lake 1.

The water taking flow channel 3 is connected with the regulation and storage lake 1 and the large lake 2, and a water taking pump station 4 is arranged on the side of the large lake 2. The upstream of the water taking channel 3 is connected with the large lake 2, the downstream is connected with the regulation and storage lake 1, the water taking pump station 4 is used for lifting the lake water to the water taking channel 3 with a certain gradient (the elevation of one end of the water taking channel 3 close to the large lake 2 is higher than that of one end close to the regulation and storage lake 1), the self weight of the lake water is used for conveying the lake water into the regulation and storage lake 1, the water level in the regulation and storage lake is stored high, and the water storage level in the regulation and storage lake is higher than that of the plain river network, so that the self-flow condition is met.

In order to prevent the water flow of the regulation lake 1 from flowing back to the large lake 2, a check gate 5 is arranged at the downstream end of the water taking flow passage 3. The water taking flow channel 3 determines a reasonable gradient according to the water taking length and the water taking water level height difference, and ensures that the plain river network can carry out self-flowing circulation through the water level height difference, thereby realizing the purpose of improving the water quality of the river network.

By utilizing the characteristic that the height difference is generated between the water storage level of the regulation lake 3 and the water level of the peripheral river network, the water taking pump station is adopted to store the high water level of the regulation lake, and the high water level flows to the peripheral river network or returns to the large lake 2 in a river self-flowing mode, so that the water body in the target area circularly flows, and the water quality of the plain river network is continuously improved.

When the landscape water level in the river channel needs to be ensured and the river flow in the river network is controlled, a check gate 5 can be arranged at the joint of the storage lake 1 and the river to realize the orderly control of the flow.

According to the utility model discloses a description and attached drawing, the field technical personnel make or use very easily the utility model discloses a promote and face the guarantee system that lake or face river plain river network quality of water to can produce the positive effect that the utility model discloses record.
