Description

Technical Field

[0001] This invention relates to the field of waste filtration technology for pumped storage power stations, and in particular to a waste filtration device for pumped storage power stations. Background Technology

[0002] Pumped-storage hydroelectric power stations, also known as pumped-storage hydroelectric power stations, are hydroelectric power stations that pump water to an upper reservoir to store energy. They utilize electricity generated during periods of low electricity demand to pump water to the upper reservoir, and then release the water to the lower reservoir to generate electricity during periods of high demand. This allows them to convert excess electricity generated during periods of low grid load into high-value electricity generated during peak periods. They are also suitable for frequency and phase regulation, stabilizing the frequency and voltage of the power system, and serve as emergency backups. Furthermore, they can improve the efficiency of thermal and nuclear power plants within the system. Pumped-storage hydroelectric power stations are experiencing rapid capacity increases and a high rate of development.

[0003] The main components of a pumped-storage power station include: an upper reservoir, a water conveyance system, a powerhouse, a switchyard and outgoing line yard, and a lower reservoir. Because the upper and lower reservoirs are located in a natural environment, debris such as branches, leaves, and garbage often float in the water. Without filtration devices, this debris can clog the pipelines, posing a risk of damage to the power station.

[0004] When water is pumped from the upper reservoir to the lower reservoir, it is done through the water inlet at the bottom of the upper reservoir. The existing method of filtering debris is to set up a filter screen at the water inlet to filter the debris. However, since it is underwater, a simple filter screen is not convenient for cleaning debris. Summary of the Invention

[0005] This invention provides a waste filtration device for pumped-storage power stations, aiming to solve the technical problem of inconvenient waste cleaning in existing pumped-storage power station waste filtration devices. This invention changes the traditional water flow method by extending the water inlet of the upper reservoir through a pipe to the water surface. Filter holes are installed on the outer side of the upper part of the pipe. Water from the upper reservoir is filtered through these holes before entering the pipe, where waste is adsorbed onto the outer side. The water entering the pipe impacts the impeller, causing it to rotate, which in turn drives the spiral blades to rotate. The spiral blades guide the waste to the water surface, where it is then transported away by a conveyor belt, achieving automatic cleaning.

[0006] The present invention provides the following technical solution to achieve the above objectives: A sewage filtration device for a pumped storage power station includes a pipe with filter holes at the top, a support fixed inside the pipe, an impeller rotatably connected to the top of the support, a rotating rod connected to the top of the impeller, a rotating block connected to the top of the rotating rod, and a spiral blade connected to the outside of the pipe.

[0007] The aforementioned pumped storage power station sludge filtration device includes a platform with holes, through which pipes and spiral blades are inserted. A conveying device is installed on the top of the platform, surrounding the outside of the spiral blades.

[0008] In the aforementioned pumped storage power station waste filtration device, the spiral blades are recessed and the top and tail ends of the spiral blades are twisted.

[0009] In the aforementioned pumped storage power station sludge filtration device, the conveying device includes a conveyor belt formed by interlocking and hinged unit plates and vertical plates arranged around the inner and outer sides of the conveyor belt. The vertical plates are installed on a platform, and chains are correspondingly arranged at the bottom of the unit plates. The outer side of the spiral blades is connected to an outer cylinder, and the outer side of the outer cylinder is connected to a gear through a first connecting block. The gear meshes with the chain.

[0010] In the aforementioned pumped storage power station sludge filtration device, an extension plate is installed on the top of the platform, surrounding the inner side of the spiral blades. The extension plate is inclined from the middle to several unit plates on both sides, and the inner vertical plate has notches at both ends of the extension plate.

[0011] In the aforementioned pumped storage power station waste filtration device, the bottom of the outer cylinder is connected to rising blades arranged around the through pipe via a second connecting block.

[0012] In the aforementioned pumped storage power station sludge filtration device, the platform is connected to a support frame at the end away from the spiral blades, and a collection bag is connected to the bottom of the support frame via a hook; a collection port is provided on the outer upright plate near the collection bag, a baffle is provided at the collection port, and an inclined plate is provided at the bottom of the collection port.

[0013] In the aforementioned pumped storage power station waste filtration device, the support frame and the platform are connected by a rotating shaft, and a tension sensor is installed between the support frame and the platform. An alarm is installed at the bottom of the platform, and a solar panel is installed at the top of the platform. The solar panel is connected to the tension sensor and the alarm.

[0014] In the aforementioned pumped storage power station waste filtration device, a set of support columns are connected to the bottom of the platform.

[0015] In the aforementioned pumped storage power station waste filtration device, a bearing is provided between the bottom of the rotating block and the top of the through pipe.

[0016] Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: 1. This invention changes the traditional water flow method. By extending the water flow hole of the upper reservoir into the water surface through a pipe, a filter hole is set on the outer side of the upper part of the pipe. Water in the upper reservoir enters the pipe after being filtered through the filter hole. The dirt is adsorbed on the outer side of the pipe. An impeller is installed inside the pipe, and a spiral blade is rotatably connected to the outer side of the pipe. The impeller and the spiral blade can be driven. The water entering the pipe impacts the impeller, causing it to rotate, which in turn drives the spiral blade to rotate. The spiral blade guides the dirt to the water surface. A platform is also set at the edge of the upper reservoir, and a conveying device is installed on the platform. The power of the conveying device is also driven by the impeller, which is more environmentally friendly. The conveying device surrounds the spiral blade. The dirt guided by the spiral blade falls onto the conveying device, and the conveying device removes the garbage, realizing automatic cleaning.

[0017] 2. The present invention connects rising blades to the bottom of the spiral blades. When the spiral blades rotate, they drive the rising blades to rotate. The rising blades disturb the water flow and generate an upward attraction, thereby attracting the dirt at the bottom to the top.

[0018] 3. This invention provides a waste collection mechanism. A collection bag is hooked on the bottom of one end of the platform via a support frame. A tension sensor is also installed between the support frame and the platform. Waste on the conveying device will fall into the collection bag. When the tension detected by the tension sensor reaches the full load weight of the collection bag, an alarm will be triggered to remind the staff to replace the collection bag in time.

Furthermore, some terms, besides indicating direction or positional relationship, may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0024] Example. A sludge filtration device for a pumped storage power station, referenced. Figure 1-8As shown, it includes a water passage pipe 1, which extends vertically from the water passage hole at the bottom of the upper reservoir to the water surface. The outer side of the upper half of the water passage pipe 1 is provided with filter holes 3. A support 4 is fixed inside the water passage pipe 1. An impeller 5 is rotatably connected to the top of the support 4. A rotating rod 6 is connected to the top of the impeller 5, and a rotating block 7 is connected to the top of the rotating rod 6. A spiral blade 8 is also rotatably provided on the outer side of the upper half of the water passage pipe 1, and the spiral blade 8 is connected to the rotating block 7. A bearing is provided between the bottom of the rotating block 7 and the top of the water passage pipe 1 to reduce friction. The spiral blade 8 is infinitely close to the water passage pipe 1 but does not contact it.

[0025] Water from the upper reservoir enters the pipe 1 through the filter hole 3. During the process of water entering through the filter hole 3, it will attract the dirt to the outside of the pipe 1 and suck it in. The water entering the pipe 1 impacts the impeller 5. The impeller 5 rotates and drives the rotating rod 6 to rotate. The rotating rod 6 drives the rotating block 7 to rotate. The rotating block 7 drives the spiral blade 8 to rotate, thereby the spiral blade 8 discharges the dirt attached to the outside of the pipe 1 upward to the water surface.

[0026] A platform 2 is constructed on the upper reservoir. The platform 2 is built on the top of the reservoir by support columns 20. The platform 2 is provided with holes through which the supply pipe 1 and the spiral blade 8 pass. A conveying device 12 surrounding the spiral blade 8 is installed on the top of the platform 2. The sewage carried out by the spiral blade 8 will fall onto the conveying device 12 and be transported away by the conveying device 12.

[0027] The recessed design of the spiral blade 8 facilitates the collection of dirt, and the recessed design can also carry out some water, which can be used to flush the extension plate 13 to prevent dirt from staying on the extension plate 13. In addition, the twisted design at the top and tail of the spiral blade 8 makes it easy for dirt to fall off the spiral blade 8.

[0028] The conveying device 12 includes a conveyor belt formed by interlocking and hinged unit plates 22, and upright plates arranged around the inner and outer sides of the conveyor belt. The upright plates are mounted on the platform 2. Chains 21 are correspondingly arranged at the bottom of the unit plates 22, and the chains 21 drive the unit plates 22. The outer side of the spiral blade 8 is connected to the outer cylinder 9, and the outer side of the outer cylinder 9 is connected to the gear 10 through the first connecting block 26. The gear 10 meshes with the chain 21. When the spiral blade 8 rotates, it drives the outer cylinder 9 to rotate. The outer cylinder 9 drives the gear 10 to rotate through the first connecting block 26, thereby driving the chain 21 to rotate, which in turn makes the conveying device 12 operate and removes the waste. The power for the operation of the conveying device 12 is also provided by the impeller 5, which is more environmentally friendly.

[0029] An extension plate 13 is installed on the top of platform 2, surrounding the inner side of the spiral blade 8. The extension plate 13 is inclined from the middle to several unit plates 22 on both sides, and the inner vertical plate has notches at both ends of the extension plate 13. Since the conveying device 12 can only surround half of the position of the spiral blade 8 (outer side), half of the dirt will not fall onto the conveying device 12 after the spiral blade 8 rotates once. Therefore, the extension plate 13 is installed so that the other half of the dirt will fall onto the extension plate 13 and slide down the notches onto the conveying device 12 and be transported away.

[0030] The bottom of the outer cylinder 9 is also connected to a rising blade 11 via a second connecting block 27. The rising blade 11 surrounds the through pipe 1. When the outer cylinder 9 rotates, it will disturb the water flow, causing the water flow to generate upward lift, thereby sucking up some garbage at the bottom and then transporting it away through the spiral blade 8.

[0031] The platform 2 is connected to a support frame 16 at the end furthest from the spiral blade 8. A collection bag 19 is connected to the bottom of the support frame 16 via a hook 18. A collection port 28 is provided on the outer upright plate near the collection bag 19. A baffle 14 is provided at the collection port 28, and an inclined plate 25 is provided at the bottom of the collection port 28. When the waste on the conveying device 12 reaches the collection port 28, it is blocked and guided by the baffle 14, and the waste slides down through the collection port 28 and the inclined plate 25 into the collection bag 19 for collection.

[0032] One end of the support frame 16 is connected to the platform 2 via a pivot 15, and a tension sensor 17 is installed between the support frame 16 and the platform. An alarm 23 is installed at the bottom of the platform 2 near the collection bag 19, and a solar panel 24 is installed on the top of the platform 2. The power generated by the solar panel 24 powers the tension sensor 17 and the alarm 23. When the tension detected by the tension sensor 17 reaches the full load weight of the collection bag 19, the alarm 23 will be triggered to remind the staff to replace the collection bag in time.

[0033] A bearing is provided between the bottom of the rotating block 7 and the top of the through pipe 1. The bearing reduces friction between the rotating block 7 and the through pipe 1.

The above embodiments are not intended to limit the present invention, and various modifications and variations can be made to the present invention by those skilled in the art.
