For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In the present invention, Figure 1-6 As shown in the figure, a water circulation pump station suitable for flood control, drainage and water replenishment is provided, including: a water collection tank 1; at least three pipes 2, the pipes 2 are connected to the lower end of the water collection tank 1; a first valve member 3, arranged at the connection between the pipe 2 and the water collection tank 1, capable of connecting and disconnecting the pipe 2 and the water collection tank 1; a water diversion tank 4, surrounding the outside of the water collection tank 1, and the bottom of the water diversion tank 4 is respectively connected to each of the pipes 2; a second valve member 5, arranged at the connection between the pipe 2 and the water diversion tank 4, capable of connecting and disconnecting the pipe 2 and the water diversion tank 4; a pumping member 7, arranged in the water collection tank 1, capable of pumping water in the water collection tank 1 to the water diversion tank 4.

[0029] When the circulating pump station of the present invention is in use, water can be supplied to the water collecting tank 1 through one or two of the pipes 2. At this time, the second valve member 5 at the water supply pipe 2 is closed and the first valve member 3 is opened, and the water in the water collecting tank 1 is discharged to the water diversion tank 4 through the pumping member 7. Since the water diversion tank 4 is located above each pipe 2, the water level in the water diversion tank 4 is higher than the water level of each pipe 2. At this time, the second valve member 5 at at least one pipe 2 in the remaining pipes 2 can be selected to open and the first valve member 3 to close. At this time, a water flow path can be formed from the water supply pipe 2 to the drainage pipe 2.

[0030] It can be seen from this that when the circulating pump station of the present invention is in use, Figure 6 As shown, each pipe 2 can be connected to different waterways of the water system 15 (the water system 15 in this embodiment refers to the collection of internal circulating waterways in the application), so that the water in the waterway can circulate and flow, and dead water can be prevented in the entire water system 15. Moreover, by opening the first valve member 3 and the second valve member 5, the flow direction of the water in the pipe 2 can be changed, so that the pipe 2 becomes an inlet pipe 2 or an outlet pipe 2, which is convenient for managing the water flow direction in the water system 15, especially for a multi-waterway water system 15, it is beneficial to distribute the water flow through the water distribution tank 4.

[0031] Moreover, one of the pipes 2 can be connected to the external water supply waterway 21. When the water system 15 needs to be replenished and the water level is low: at this time, if the water volume in the external water supply waterway 21 is large and the water level is high, the first valve member 3 of each pipe 2 can be directly opened, and the water in the water supply waterway 21 can flow into the remaining pipes 2 and enter the water system 15 after entering the water collection tank 1; when the water volume in the external water supply waterway 21 is not enough to flow into the water system 15, the first valve member 3 of the pipe 2 connected to the water supply waterway 21 can be opened, and the second valve member 5 can be closed, and the first valve members 3 of the remaining pipes 2 can be closed and the second valve members 5 can be opened. At this time, the water supply waterway 21 enters the water collection tank 1, and the water is pumped into the water distribution tank 4 through the pumping member 7, and then enters the remaining pipes 2 through the water distribution tank 4, and the water replenishment can be completed.

[0032] When the amount of water in the water system 15 is too large and the water level is high, it is necessary to drain the water to the outside: if the amount of water in the water replenishment waterway 21 is small and the water level is low, at this time, the first valve member 3 of each pipeline 2 can be directly opened, and the water of the water system 15 enters the water collecting tank 1 and flows to the pipeline 2 connected to the water replenishment waterway 21. At this time, the water replenishment waterway 21 becomes a drainage waterway; when the amount of water in the water replenishment waterway 21 is large and the water level is high, the first valve member 3 of the pipeline 2 connected to the water replenishment waterway 21 can be closed and the second valve member 5 can be opened, and the first valve members 3 of the remaining pipelines 2 can be opened and the second valve members 5 can be closed. At this time, the water replenishment waterway 21 enters the water collecting tank 1, and the water is pumped into the water diversion tank 4 through the pumping member 7, and then enters the pipeline 2 connected to the water replenishment waterway 21 through the water diversion tank 4, which can complete the drainage of the water system 15 and play a role in flood prevention and drainage.

[0033] During the above-mentioned water replenishment and drainage process, the first valve member 3 and the second valve member 5 corresponding to each pipeline 2 connected to the water system 15 can be opened and closed, thereby replenishing or draining water in the water channel connected to the single pipeline 2.

[0034] To sum up, the flood control, drainage, water replenishment, and water system circulation pump station of the present invention can promote the circulation and flow of water in the water system 15, and can also adjust the direction of the water flow in the water system 15. Moreover, when the pipeline 2 is connected to the external water replenishment waterway, it is also convenient for water replenishment and drainage.

[0035] It should be noted that the above-mentioned embodiments are merely examples of the use of the circulation pump station of the present invention and are not intended to limit the use of the present invention. In alternative embodiments, the pipeline 2 may not be connected to the external water replenishment waterway 21, and the pipeline 2 is only connected to the waterway within the water system 15. In this way, the pump station only circulates within the water system 15, and the water replenishment of the water system 15 can rely on natural precipitation or direct flow into the waterway from a well.

[0036] Moreover, the above-mentioned water replenishment waterway 21 is preferably an active river, and the pipeline 2 can be connected not only to one water replenishment waterway 21 but also to multiple water replenishment waterways 21.

[0037] The pipeline 2 may be a concrete culvert or a concrete pipeline 2 or a metal pipeline 2 or a plastic pipeline 2 .

[0038] A further optimization is that an overflow tank 6 surrounding the outside of the water collecting tank 1 is provided between the water collecting tank 1 and the water diversion tank 4, and the pumping member 7 can pump the water in the water collecting tank 1 to the overflow tank 6, so that the water overflowing from the overflow tank 6 can overflow into the water diversion tank 4. As shown in the figure, by setting the overflow tank 6, the water entering the water diversion tank 4 can be more uniform, so that when the second valve member 5 with multiple pipes 2 is opened to inlet water and the first valve member 3 is closed, the water in the water diversion tank 4 can flow evenly into each opened second valve member 5; and, by setting the overflow tank 6, the water can be fully in contact with the air during the overflow process, which can inhibit and eliminate anaerobic microorganisms and play a certain role in sewage purification; and, the water head pumped out by the pumping member 7 is relatively high, and the water overflows and flows down from the overflow tank 6 in a dispersed manner, which can reduce the impact force of water rushing down directly from a high place.

[0039] In a preferred embodiment, more specifically, the outer side of the water collecting pool is surrounded by an overflow wall 8, and the outer side of the overflow wall 8 is surrounded by a water dividing wall 9, the overflow wall 8 and the outer wall of the water collecting pool 1 form the overflow pool 6, and the overflow wall 8 and the water dividing wall 9 form the water dividing pool 4. As shown in the figure, the pipeline 2 is connected to the water collecting pool 1 from the lower side of the bottom wall of the water dividing pool 4.

[0040] A further optimization is that the bottom wall of the overflow pool 6 is not lower than the bottom wall of the water diversion pool 4, and the overflow wall 8 is provided with a drain port 10 at the bottom wall of the overflow pool 6, and a drain valve 11 is provided at the drain port 10. As shown in the figure, when overflow is not required, the water pumped into the overflow pool 6 by the pumping member 7 can quickly enter the water diversion pool 4 through the drain valve 11, thereby realizing low head operation. At the same time, when the overflow pool 6 is cleaned, the water in the overflow pool 6 can be quickly discharged through the drain valve 11. Moreover, when the water volume of the water system 15 and the water replenishment waterway 21 is too large, and the water in the water system 15 needs to be discharged into the water replenishment waterway 21, the drain valve 11 can be opened so that the water in the overflow pool 6 can quickly enter the water diversion pool 4, and then quickly enter the pipe 2 connected to the water replenishment waterway.

[0041] Among them, in a specific embodiment, Figure 1 As shown, a drain pipe can be provided at the drain outlet 10, and the drain valve 11 is a flange baffle connected to the drain outlet 10. Alternatively, as Figure 4 As shown, the drain valve 11 is a manual ball valve arranged on the drain pipe.

[0042] More specifically, the overflow wall 8 is annular, and the water dividing wall is annular. Figure 1 As shown, the force on the pump station is more uniform and symmetrical, making the entire pump station more stable.

[0043] To be more specific, Figure 2 As shown, the first valve member 3 includes a gate plate 13 vertically slidably disposed between the water collecting tank 1 and the pipeline 2, and a driving member 12 driving the gate plate 13 to move up and down, and the driving member 12 can drive the gate plate 13 to switch between blocking and opening the pipeline 2. Figure 3 As shown, the drive member 12 can be selected from existing sluice lifting mechanisms.

[0044] Preferably, more specifically, the pipeline 2 extends from the bottom of the water dividing pool 4 to the water collecting pool 1 and is connected to the water collecting pool 1, the bottom wall of the water dividing pool 4 is provided with a through hole 14 connected to the pipeline 2, and the second valve member 5 can close the through hole 14. As shown in the figure, through such an arrangement, the water in the fractional pool can quickly enter the pipeline 2.

[0045] As for the structure of the second valve member 5, to be more specific, the second valve member 5 includes a closing plate 16 closing the through hole 14, one end of the closing plate 16 is hinged to the bottom wall of the water diversion pool 4, and the other end is connected to the side wall of the water diversion pool 4 through a retractable lifting member 17. Figure 1 As shown, the lifting member 17 can be a cylinder.

[0046] Or, in an alternative embodiment, Figure 4 As shown, the second valve member 5 comprises: a closing plate 16, comprising two adjacent plate bodies 18, the inner sides of the plate bodies 18 are respectively rotatably connected to the bottom wall of the water diversion pool 4; a lifting member 17, comprising two pull rods 19, a lifting rod 19 hinged to the upper ends of the two pull rods 19, and the lower ends of the two pull rods 19 are respectively hinged to the outer ends of the two plate bodies 18. Figure 4 As shown, the through hole 14 between the plates 18 is provided with a rotating shaft connected to the bottom wall of the water diversion pool 4, and the two plates 18 are rotatably connected to the rotating shafts. When the pull rod 19 moves upward, the two ends of the two plates 18 can be pulled up to open the through hole 14. When the pull rod 19 moves downward, the plates 18 can be pressed against the bottom wall of the water diversion pool 4 by the two pull rods 19. The lifting mechanism of the lifting rod can select the lifting mechanism in the existing sluice, or directly use the oil cylinder.

[0047] The present invention also provides a circulating water system, such as Figure 5 As shown, it includes the above-mentioned circulating pump station, and the pipelines 2 are provided with four, one of which is a water supply pipeline 2 connected to an external water supply river, and the other three pipelines 2 are respectively connected to at least one river channel, and the river channels are connected to each other at one end away from the pipeline 2. Figure 5 As shown, the pipes 2 on the left and right sides are respectively connected to a waterway, and both waterways are equipped with wetland parks. The lower pipe 2 is connected to the return waterway, and the upper pipe 2 is connected to the external water supply waterway 21. During normal use, the water flows in the direction shown in the figure, and the water system 15 can complete the internal circulation at this time. When water supply is needed, the first valve member 3 of the upper pipe 2 is opened and the second valve member 5 is closed, and then the first valve members 3 and the second valve members 5 of the remaining three pipes 2 are selected to be opened and closed according to the water level of the water supply waterway 21. When draining water, it is only necessary to close the first valve member 3 of the upper pipe 2 and open the second valve member 5, and then the first valve members 3 and the second valve members 5 of the remaining three pipes 2 are selected to be opened and closed according to the water level of the water supply waterway 21.
