Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] like Figure 1 As shown, this embodiment provides a river and lake water purification and drought relief system, including a river 1, two lakes 2, three water storage units, and a water lifting device 8.

[0025] The three water storage units are designated as first water storage unit 3, second water storage unit 4, and third water storage unit 5, with their elevations decreasing sequentially. First water storage unit 3 and second water storage unit 4 are adjacent units connected by a ditch 6, allowing water in first water storage unit 3 to flow naturally to second water storage unit 4. Second water storage unit 4 is located in... Figure 1 On the high ground on the left bank of Lake 2, the second water storage unit 4 is connected to Lake 2 via a ditch 6, allowing water in the second water storage unit 4 to flow naturally to Lake 2. The first water storage unit 3 and the third water storage unit 5 are located on... Figure 1 On the high ground on the right bank of Lake 2, the first water storage unit 3 is connected to Lake 2 on the right through a ditch 6, so that the water in the first water storage unit 3 can flow naturally to Lake 2 on the right. The elevation of the third water storage unit 5 is lower than that of Lake 2 on the left and higher than that of Lake 2 on the right. The third water storage unit 5 is connected to both Lake 2 through the ditch 6, so that the water in Lake 2 on the left can flow to Lake 2 on the right through the third water storage unit 5, thus forming a loop between the two lakes 2 and the three water storage units.

[0026] In this embodiment, the first water storage unit 3 and the third water storage unit 5 are ponds and weirs, and the second water storage unit 4 is a reservoir. Ponds, weirs, puddles, and swamps on hillsides can all be used as water storage units, reducing the amount of construction work required for this system.

[0027] Both lakes 2 are connected to river 1 via canals 6. The elevation of lake 2 on the left is lower than that of river 1, and the elevation of lake 2 on the right is lower than that of river 1. The elevation of the third reservoir 5 is lower than that of river 1. The third reservoir 5 is connected to river 1 via canals 6, allowing water from river 1 to flow naturally into the third reservoir 5 and lake 2 on the left. A control gate 13 is installed on the canal 6 connecting lake 2 and river 1 to regulate the amount of water entering and leaving lake 2.

[0028] Water lifting devices 8 are installed beside the left lake 2, the right lake 2, the second water storage unit 4, and the third water storage unit 5. They are used to lift water from the left lake 2 to the second water storage unit 4, water from the right lake 2 to the first water storage unit 3, water from the second water storage unit 4 to the first water storage unit 3, and water from the third water storage unit 5 to the left lake 2. All water lifting devices 8 use water conveyance pipes 12, which are arranged along the ditch 6.

[0029] It should be noted that the setting of the water lifting device 8 should be determined according to the elevation of the river, lake, and water storage unit. When the elevation of the two lakes 2 and the three water storage units is higher than that of the river 1, water can be supplied to the water storage unit closest to the river 1 through the water lifting device 8, thereby realizing the water circulation between the river 1, the lake 2, and the water storage unit.

[0030] Overflow outlets 14 are provided on the lake 2 on the left and on the three water storage units. When the water level reaches a certain height, the water can flow out from the overflow outlets 14. The overflow outlet 14 of the first water storage unit 3 is located on the side of the first water storage unit 3 near the right lake 2. The overflow outlet 14 of the second water storage unit 4 is located on the side of the second water storage unit 4 near the left lake 2. The overflow outlet 14 of the third water storage unit 5 is located on the side of the first water storage unit 3 near the right lake 2. The overflow outlet 14 of the left lake 2 is located on the side of the left lake 2 near the third water storage unit 5. Ecological grass slopes 7 are provided between the first water storage unit 3 and the right lake 2, between the second water storage unit 4 and the left lake 2, between the left lake 2 and the third water storage unit 5, and between the third water storage unit 5 and the right lake 2. The water flowing out of the overflow outlets 14 can irrigate the ecological grass slopes 7, and the ecological grass slopes 7 can also purify the water flowing out of the overflow outlets 14.

[0031] Figure 1 The arrows in the diagram indicate the direction of water flow in ditch 6 and the direction of water flow on the ecological grass slope 7.

[0032] In this embodiment, duckweed 11 is planted in lake 2, water storage unit, and ditch 6, and aquatic plants are planted on the bottom and inner wall of ditch 6. The aquatic plants are low-growing to reduce resistance to water flow. Both duckweed 11 and aquatic plants can adsorb, filter, and transform impurities in the water, thereby purifying the water.

[0033] The working principle of this river and lake water purification and drought relief system is as follows:

[0034] When the water lifting device 8 is not working, the water in the river 1 enters the lake 2 on the left through the ditch 6. The water in the lake 2 on the left flows back into the river 1 through the third water storage unit 5 and the lake 2 on the right.

[0035] When the water lifting device 8 is working, the water in the lake 2 on the right and the water in the second water storage unit 4 are lifted into the first water storage unit 3. The water in the first water storage unit 3 will flow back to the lake 2 on the right and the second water storage unit 4. The water in the lake 2 on the left is lifted into the second water storage unit 4. The water in the second water storage unit 4 will flow back to the lake 2 on the left. The water in the third water storage unit 5 is lifted into the lake 2 on the left. The water in the lake 2 on the left will flow back to the second water storage unit 4. During the above flow process, the plants in the first water storage unit 3, the second water storage unit 4, the two lakes 2, and the ditch 6 can all purify the water.

[0036] When the water level in the first water storage unit 3 is higher than the overflow outlet 14, the water in the first water storage unit 3 flows out from the overflow outlet 14, flows through the ecological grass slope 7 and then flows into the lake 2 on the right. When the water level in the second water storage unit 4 is higher than the overflow outlet 14, the water in the second water storage unit 4 flows out from the overflow outlet 14, flows through the ecological grass slope 7 and then flows into the lake 2 on the left. When the water level in the lake 2 on the left is higher than the overflow outlet 14, the water in the lake 2 on the left flows out from the overflow outlet 14, flows through the ecological grass slope 7 and then flows into the third water storage unit 5. When the water level in the third water storage unit 5 is higher than the overflow outlet 14, the water in the third water storage unit 5 flows out from the overflow outlet 14, flows through the ecological grass slope 7 and then flows into the lake 2 on the right. During the above flow process, the water can irrigate the vegetation on the hillside, and the water body is ecologically filtered, adsorbed, decomposed and purified by the ecological grass slope 7, thereby purifying the water quality.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
