Description

Technical Field

[0001] The invention belongs to the technical field of rainwater storage and regulation in sponge cities, and in particular relates to a diversion system for an artificial storage lake in a sponge city. Background Art

[0002] The regulation lake is an important way to store, purify and reuse rainwater in the concept of sponge city. In addition to the use of natural lakes, artificial lakes are often used in cities for rainwater regulation. Artificial lakes are set between rainwater drainage pipes. According to the sponge city regulation index, the rainwater that needs to be regulated is stored in the lake to relieve the drainage pressure and then discharged after the peak rainfall period. At present, the artificial regulation lake is in the purpose of optimizing water flow conditions to avoid "short flow" and the water body must flow through the lake to be fully purified. The rainwater inlet and outlet are mostly arranged along the diagonal direction of the lake body. This arrangement is easy to achieve in newly built drainage planning areas, but in the old city with a high degree of construction, when sponge transformation is carried out and a regulation lake is added to the original pipeline, the inlet and outlet positions on both sides are fixed, and this arrangement is difficult to achieve.

[0003] The existing pipelines have been transformed into sponge types, and the positions of the inlet and outlet pipes on both sides are fixed. Direct use will cause the new rainwater to be discharged directly along the shortest path according to the "short-term flow effect" without flowing through the entire lake, making it impossible for the entire lake area to circulate water, turning it into "dead water", forcing relevant purification measures to be taken. Aquatic plant and animal communities can only be arranged on one side of the inlet and outlet pipes, and the lake area cannot be utilized together. Summary of the invention

[0004] In order to solve the above technical problems, the present invention belongs to the technical field of rainwater storage and regulation in sponge cities, and in particular, relates to a diversion system for an artificial storage lake in a sponge city.

[0005] The technical solution adopted by the present invention is: a diversion system for an artificial regulating lake in a sponge city, comprising an inlet area, an outlet area, a diversion dam, a water pump flow promoter and a submersible pump, characterized in that: the inlet area and the outlet area are located at both ends of the artificial regulating lake; the diversion dam is arranged between the water inlet and the water outlet; the water pump flow promoter and the submersible pump are arranged in the artificial regulating lake.

[0006] Preferably, the diversion dam comprises a first diversion dam and a second diversion dam, and the first diversion dam and the second diversion dam can separate the artificial storage lake into an S-shape.

[0007] Preferably, the diversion dam comprises a retaining wall, and the height of the retaining wall is at least 50 cm higher than the normal water level of the artificial storage lake.

[0008] Preferably, the water inlet area and the water outlet area include a drain outlet, and the drain outlet is an eight-shaped drain outlet.

[0009] Preferably, the water pump flow promoter is arranged relatively in the artificial storage lake of the first diversion dam, and the water pump flow promoter cooperates with the water flow in the water inlet area to form the water flow in the lake.

[0010] Preferably, the submersible pump is disposed in the artificial storage lake in front of the second diversion dam, and the submersible pump guides water to the water outlet area.

[0011] Preferably, a method for using a diversion system of an artificial storage lake in a sponge city is characterized by comprising the following steps:

[0025] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of the technology of the known structure is omitted to avoid unnecessary confusion of the concept of the present invention.

[0026] The structural schematic diagram of an embodiment of the present invention includes an inlet area 1, a first diversion dam 2, a water pump flow generator 3, a second diversion dam 4, a submersible pump 5 and an outlet area 6.

[0027] The water inlet area 1 and the water outlet area 6 are respectively set at the two ends of the artificial storage lake. Figure 3 The figure shows a schematic diagram of a drain outlet of an embodiment of the present invention, including a drain pipe 10 and an eight-shaped drain outlet 11, wherein the drain pipe 10 is a large pipe suitable for an artificial lake, and a filter screen is also installed in the drain pipe 10. The design of the drain pipe 10 ensures that the water in the artificial storage lake flows quickly and remains unobstructed. The filter screen can filter some larger garbage and impurities out of the artificial storage lake, thereby ensuring the water quality in the artificial storage lake and facilitating cleaning; the eight-shaped drain outlet 11 is arranged at the outlet of the drain pipe 10, which speeds up the water flow speed at the outlet and allows for faster drainage and water inflow.

[0028] like Figure 1 As shown, the first diversion dam 2 and the second diversion dam 4 are respectively built on the artificial storage lake and between the water inlet area 1 and the water outlet area 6. The first diversion dam 2 is built near the water inlet area 1, and the second diversion dam 4 is built near the water outlet area 6. Because of the establishment of the diversion dam, the artificial storage lake is shaped into an S shape, so that the newly entered rainwater flows out along the diversion dam and flows through most of the lake body according to the designed flow direction for water circulation; the first diversion dam 2 and the second diversion dam 4 include the following Figure 2 The platform 7, railing 8 and retaining wall 9 shown in the figure, wherein the height of the retaining wall 9 is higher than the normal water level of the artificial storage lake and not lower than the normal water level by 50 cm, the platform 7 can be designed as an artificial landscape peninsula and a hydrophilic platform according to demand, so that the first diversion dam 2 and the second diversion dam 4 not only play the role of diverting lake water and new rainwater, but also reflect the lake water to become the landscape of the artificial storage lake, enrich the lake view, and also add a touch of color to the urban scenery and convenient life.

[0029] A water pump flow promoter 3 is installed in the artificial regulating lake near the water inlet area 1 and the first diversion dam 2, and a submersible pump 5 is installed in the artificial regulating lake near the water outlet area 6 and the second diversion dam 4. The water pump flow promoter 3 guides the lake water and the newly incoming rainwater in the water inlet area 1, and the submersible pump 5 simultaneously guides the lake water and the newly incoming rainwater to be discharged through the water outlet area 6. They cooperate in the artificial regulating lake to further promote water circulation, adjust the water flow direction again, and avoid a certain degree of short-circuit.

[0030] Embodiment 1:

[0031] An inlet area 1 and an outlet area 6 are designed and installed in the artificial regulating lake, and the inlet area 1 and the outlet area 6 are respectively located at the two ends of the artificial regulating lake. A first diversion dam 2 and a second diversion dam 4 are designed and constructed in the lake. The two diversion dams make the artificial regulating lake S-shaped, forming a river-like shape to promote water flow; the first diversion dam 2 and the second diversion dam 4 include a retaining wall 9, and the height of the retaining wall 9 is at least 50 cm higher than the normal water level of the artificial regulating lake; the first diversion dam 2 is close to the inlet curve 1, and the second diversion dam 4 is close to the outlet area 6. A water pump thruster 3 is installed in the artificial regulating lake opposite to the first diversion dam 2, and a submersible pump 5 is installed in the artificial regulating lake near the second diversion dam 4.

[0032] After the artificial storage lake is filled with water, more new rainwater will flow into the lake on rainy days. The artificial storage lake needs to divert the original lake water and the new rainwater. The first diversion dam 2 and the second diversion dam 4 make the artificial storage lake form a river shape to promote the rapid flow of lake water. The water pump flow promoter 3 and the submersible pump 5 are started to further promote water circulation and adjust the water flow direction again.

[0033] This embodiment solves the problem of water circulation failure caused by the short-flow effect to a large extent. By utilizing the hydrophilic platform and the viewing peninsula as diversion dams and reasonably arranging the purification equipment, water circulation is promoted, water quality and landscape effects are improved, the original drainage pipes can be used normally, and the construction of new rainwater pipes is avoided, saving construction costs. It has broad application prospects in the sponge transformation of old urban areas.

[0034] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
