[0002] A drainage pumping station is a facility used to lift and discharge wastewater, usually set in the middle and end of the drainage pipeline to play a role when wastewater needs to be lifted. The main components of the drainage pumping station include a pump house and a sump. In the pump house, there is a unit composed of a water pump and a power device.

Detailed Description of the Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a diversified drainage pumping station for large reservoirs as shown in Figure 1 - Figure 4 which includes a pumping station body 1 and a plurality of conveying water pumps 2 fixedly arranged in the pumping station body 1, mainly used for conveying water. One end of the pumping station body 1 is communicated with a water inlet pipe 3. A fixed vane 4 for blocking impurities is fixedly arranged inside the water inlet pipe 3. A self-rotating impeller 7 is rotatably arranged at one end of the fixed vane 4. A plurality of first water inlet holes 11 are formed through one side of the fixed vane 4, and a plurality of second water inlet holes 12 are formed through one side of the self-rotating impeller 7 to increase the water flow rate.

[0024] A conical surface 5 is arranged at one end of the fixed vane 4 close to the self-rotating impeller 7. A plurality of filter holes 6 are formed through one side of the conical surface 5 for main filtration. A through hole for discharging impurities is formed inside the water inlet pipe 3.

[0025] A plurality of power blades 8 are fixedly arranged on the side of the self-rotating impeller 7 away from the fixed vane 4. The self-rotating impeller 7 is driven to rotate by the flow of water. A plurality of scraping plates 9 are fixedly arranged on the outside of the self-rotating impeller 7. The scraping plates 9 are attached to the conical surface 5 to scrape off impurities.

[0026] A baffle 10 is fixedly arranged on one side of the scraping plate 9. Through the arrangement of the self-rotating impeller 7, when the water inlet pipe 3 intakes water, the flow rate of the water can be utilized to automatically scrape away the impurities on the filter holes 6 to complete automatic cleaning. Its use cost is low. By using the flow of water and the centrifugal force when the self-rotating impeller 7 rotates, the impurities are thrown away for collection.

[0027] Through the arrangement of the first water holes 11 and the second water inlet holes 12, the water flow rate is increased, and when the self-rotating impeller 7 rotates, the centrifugal force of the water is utilized to throw the impurities into the filter holes 6.

[0028] One end of the water inlet pipe 3 corresponding to the pump station body 1 is fixedly provided with a collection bin 15. The collection bin 15 is communicated with the water inlet pipe 3 through a through hole. A water collection cavity 16 is arranged inside the collection bin 15. A filter plate 17 is fixedly arranged inside the water collection cavity 16. The collection bin 15 and the water collection cavity 16 are separated by the filter plate 17. A siphon pipe 18 is communicated and arranged inside the water collection cavity 16. The end position of the siphon pipe 18 inside the water collection cavity 16 is higher than the height inside the pump station body 1 to ensure the siphon effect. When starting the siphon, an integrated water pump can be set separately to start the siphon effect. When the integrated water pump is turned off, one end of the siphon pipe 18 away from the water collection cavity 16 is arranged inside the pump station body 1. Through the arrangement of the siphon pipe 18, the water in the collection bin 15 is automatically discharged to make the water flow in a flowing state, and the water flow drives the impurities to flow into the collection bin 15.

[0029] An acceleration ring 14 is fixedly arranged inside the water inlet pipe 3. The cross section of the acceleration ring 14 is in a conical shape, so that when the water flow enters the water inlet pipe 3, the water flow velocity is increased to increase the rotation speed of the self-rotating impeller 7.

[0030] One end of the self-rotating impeller 7 away from the fixed vane 4 is fixedly provided with a conical head 13. The conical head 13 is fixedly connected to the end of the power vane 8 to ensure the fluidity of the water flow.

[0031] A pipe for discharging impurities is fixedly arranged at the lower end of the collection bin 15. When not draining water, the impurities in the collection bin 15 are cleared. Water is injected into the collection bin 15 by the integrated water pump, and then the impurities in the collection bin 15 are quickly flushed out.

[0032] Working principle: When the pump station body 1 needs to drain water, the water inlet pipe 3 is opened to make the water flow into the inside of the water inlet pipe 3. Then, through the arrangement of the acceleration ring 14, the water flow velocity is increased. The water flow drives the self-rotating impeller 7 to rotate through the power vane 8. Then, the self-rotating impeller 7 drives a plurality of scraping plates 9 to rotate, so that the scraping plates 9 scrape the surface of the filter holes 6 on the conical surface 5, collect the impurities staying on the filter holes 6, and then drive the impurities into the inside of the collection bin 15. Then, the water in the water collection cavity 16 is pumped out through the siphon pipe 18, and the filter plate 17 is used to prevent impurities from entering the siphon pipe 18.
