Therefore, trash racks are installed at the turbine inlet to prevent debris from entering the turbine and causing head loss and equipment damage. During use, a large amount of debris adheres to and accumulates on the trash racks, which not only affects their trash-blocking effect but also shortens their service life. Utility Model Content
[0003] In view of this, the purpose of this application is to propose a trash rack for a storage power station and a storage power station, so as to solve the problem that the trash rack is affected by the accumulation of a large amount of debris during the use of the trash rack.
[0004] To achieve the above objectives, this application provides a trash rack for a storage power station, comprising:
[0005] Rotating shaft;
[0006] The debris-blocking impeller, wherein a plurality of the debris-blocking impellers are arranged along the length of the rotating shaft and rotate with the rotating shaft;
[0007] A cleaning rod is located between two adjacent debris-blocking paddles. One end of the cleaning rod is rotatably connected to the rotating shaft to keep its position fixed when the debris-blocking paddle rotates with the rotating shaft. The projection of its other end on the debris-blocking area formed by the debris-blocking paddle is set close to the edge of the debris-blocking area.
[0008] Optionally, the cleaning rod is a helical rod, which is an arc-shaped rod structure arranged around the rotation axis, and gradually moves away from the rotation axis along the water flow direction.
[0009] Optionally, the screw rod includes a first helical part and a second helical part. The first helical part is a counterweight and is sleeved on the rotating shaft through a bearing and rotatably connected to the rotating shaft. The first helical part and the second helical part are integrally formed.
[0010] Optionally, each of the debris-blocking paddles includes a plurality of arc-shaped rods, which are fixed to the periphery of the rotating shaft.
[0011] Based on the same inventive concept, this disclosure also provides an energy storage power station, including the energy storage power station trash rack as described in any of the preceding claims;
[0012] The water tank has two ends of the rotating shaft that are rotatably connected to two opposite side walls of the water tank, and its bottom is close to the bottom of the water tank to prevent garbage from passing through the bottom of the water tank.
[0013] The storage tank is located on one side of the debris-blocking paddle along the direction of water flow.
[0014] Optionally, the bottom of the water tank is provided with the flow channel facing downwards, the bottom of the storage tank is located in the flow channel, and the two opposite side walls of the storage tank along the length of the rotation axis are respectively connected to the two opposite side walls of the flow channel. The other two side walls and the bottom wall of the storage tank are left with gaps between them and the wall of the flow channel to allow water to flow through.
[0015] Optionally, the storage tank has its side away from the debris-blocking paddle protruding above the water surface to form a debris-blocking plate, and the side of the storage tank near the debris-blocking grid of the power station is lower than part of the debris-blocking paddle to facilitate the falling of debris from the debris-blocking paddle into the storage tank.
[0016] Optionally, a comb plate is installed on the upper end of the storage tank near the debris barrier, and the comb plate is attached to the side of the auger away from the rotating shaft to restrict the auger from rotating with the water flow.
[0017] Optionally, the energy storage power station also includes an installation slot, which is disposed on one side of the water tank. A drive assembly is disposed in the installation slot, and one end of the rotating shaft extends into the installation slot and is driven by the drive assembly.
[0018] Optionally, the drive assembly includes a motor, a first sprocket, a chain, and a second sprocket. The output shaft of the motor is fixedly connected to the first sprocket, and the second sprocket is fixedly connected to one end of the rotating shaft. The first sprocket and the second sprocket rotate synchronously through the chain, and the diameter of the first sprocket is smaller than the diameter of the second sprocket.
[0019] As can be seen from the above, the energy storage power station trash rack provided in this application includes a rotating shaft and trash rack slurry. Therefore, the trash rack in this application is a rotating trash rack. The rotating trash rack can effectively intercept debris on the water surface and automatically clean the debris on the trash rack by utilizing its own rotating structure. In addition, when the trash rack slurry rotates, the cleaning rod pushes outward the debris such as plastic bags wrapped around the trash rack slurry, thereby causing the debris on the trash rack slurry to be peeled off, further realizing the cleaning of the trash rack, thereby improving the trash rack's interception effect and extending its service life.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0027] As mentioned in the background, in the upstream area of pumped power stations, reservoirs often contain a lot of floating debris such as branches, leaves, and garbage bags. Therefore, trash racks are installed at the turbine inlet to prevent debris from entering the turbine and causing head loss and equipment damage. During use, a large amount of debris adheres to and accumulates on the trash racks, which not only affects their debris-blocking effect but also shortens their service life.
[0028] To address the aforementioned problems, this application designs a trash rack for a storage power station, such as... Figure 1 and Figure 2 As shown, including
[0029] Rotating shaft 2;
[0030] The debris-blocking paddles 3, a plurality of the debris-blocking paddles 3 are arranged along the length of the rotating shaft 2 and rotate with the rotating shaft 2;
[0031] The cleaning rod 4 is located between two adjacent debris-blocking paddles 3. One end of the cleaning rod 4 is rotatably connected to the rotating shaft 2 so as to keep the position fixed when the debris-blocking paddle 3 rotates with the rotating shaft 2. The projection of the other end of the cleaning rod 4 onto the debris-blocking area formed by the debris-blocking paddle 3 is set close to the edge of the debris-blocking area.
[0032] Specifically, such as Figure 1 As shown, a cleaning rod 4 is provided between each of two adjacent debris-blocking slurries 3. One cleaning rod 4 can clean the debris on the debris-blocking surface of two adjacent debris-blocking slurries 3 at the same time, which can further improve the cleaning efficiency of the arc-blocking slurry.
[0033] In this embodiment, the debris barrier is a rotating debris barrier. The rotating debris barrier can effectively intercept debris on the water surface and automatically cleans the debris from the barrier using its own rotating structure. Furthermore, one end of the cleaning rod 4 is rotatably connected to the rotating shaft 2, thus allowing the cleaning rod 4 to maintain a relatively fixed position when the rotating shaft 2 rotates. Because the debris-blocking paddle 3 rotates and the cleaning rod 4 is fixed in position, when the debris-blocking paddle 3 rotates, the cleaning rod 4 can push outwards debris such as plastic bags wrapped around it, thereby peeling off the debris from the paddle 3. The coordinated movement of the debris-blocking paddle 3 and the cleaning rod 4 further cleans the debris barrier, thereby improving its debris-blocking effect and extending its service life. The projection of the end of the cleaning rod 4 away from the rotating shaft 2 onto the debris-blocking area formed by the debris-blocking paddle 3 is positioned close to the edge of the debris-blocking area to expand the cleaning area of the cleaning rod 4 on the debris-blocking paddle 3, thus enabling a more thorough cleaning of the paddle 3 and further improving its cleaning effect.
[0034] Furthermore, such as Figure 1 and Figure 2As shown, each of the debris-blocking paddles 3 includes multiple arc-shaped rods 31, which are fixed to the periphery of the rotating shaft 2. The arc-shaped rods 31 are evenly arranged along the axis of the rotating shaft 2, and the end of the arc-shaped rod 31 away from the rotating shaft 2 adopts a flat end design.
[0035] In this embodiment, the debris-blocking paddle 3 is composed of multiple arc-shaped rods 31. Compared to straight rods, the arc-shaped rods 31 can rotate, thus better adapting to changes in water flow, reducing resistance when water flows through, and withstanding greater water flow impact and debris load, thereby extending the service life of the debris-blocking grid. The flat-end design at the tail of the arc-shaped rods 31 facilitates the removal of debris from the arc-shaped rods 31 by the cleaning rods 4, improving the cleaning effect of the cleaning rods 4 on the arc-shaped rods 31.
[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the cleaning rod 4 is a spiral rod 41, which is an arc-shaped rod structure arranged around the rotating shaft 2, and it gradually moves away from the rotating shaft 2 along the water flow direction.
[0037] In addition, the screw rod 41 includes a first screw part 411 and a second screw part 412. The first screw part 411 is a counterweight part and is sleeved on the rotating shaft 2 through a bearing and rotatably connected to the rotating shaft 2. The first screw part 411 and the second screw part 412 are integrally formed.
[0038] In this embodiment, the cleaning rod 4 is configured as a spiral structure, mainly because the spiral rod 41 can better adapt to changes in water flow, reduce resistance when water flows through, and withstand greater water flow impact, thereby extending the service life of the cleaning rod 4. The spiral rod 41 is sleeved on the rotating shaft 2 through a bearing, so that the position of the spiral rod 41 can be kept relatively fixed. Furthermore, the first spiral part 411 is a counterweight part, which increases the weight of the end of the spiral rod 41 near the rotating shaft, further improving the stability of the spiral rod 41. In addition, one cleaning rod 4 is disposed between two adjacent debris-blocking paddles 3, and the two adjacent debris-blocking paddles 3 can limit the spiral rod 41, thereby further maintaining the fixed position of the cleaning rod 4 when the rotating shaft 2 rotates.
[0039] Based on the same inventive concept, corresponding to any of the above embodiments, this application also provides an energy storage power station, such as... Figure 1 and Figure 2 As shown, it includes the trash rack of the energy storage power station as described above;
[0040] Water tank 5, the two ends of the rotating shaft 2 are respectively rotatably connected to the two opposite side walls of the water tank 5, and its bottom is close to the bottom of the water tank 5 to prevent garbage from passing through the bottom of the water tank 5;
[0041] Storage tank 6 is located on one side of the debris-blocking paddle 3 along the water flow direction.
[0042] Specifically, a transition arc surface 53 is provided at the bottom of the water tank 5. The transition arc surface 53 is located directly below the arc rod 31. The transition arc surface 53 is a circular arc surface cut out by the arc rod 31 at the bottom of the water tank 5 with the distance between itself and the rotating shaft 2 as the radius. The arc length of the transition arc surface 53 is equal to the arc length formed between the outer ends of two adjacent arc rods 31. When the rotating shaft 2 rotates, at least one arc rod 31 is located in the area of the transition arc surface 53 to prevent garbage from passing through the transition arc surface 53.
[0043] In this embodiment, the trash rack is located between the two vertical side walls of the water tank 5, which can intercept the trash in the water tank 5 to the greatest extent. The storage tank 6 can store the trash that the cleaning rod 4 cleans from the arc rod 31, preventing the trash from flowing away with the water and affecting the normal operation of the water turbine.
[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the bottom of the water tank 5 is provided with the flow channel 51 facing downwards. The bottom of the storage tank 6 is located in the flow channel 51. The two opposite side walls of the storage tank 6 along the length of the rotation axis 2 are respectively connected to the two opposite side walls of the flow channel 51. A gap 52 is left between the other two side walls and the bottom wall of the storage tank 6 and the wall of the flow channel 51 to allow water to flow through.
[0045] Specifically, the flow channel 51 is a regular rectangular channel that can accommodate storage boxes 6 of different shapes. The opening of the flow channel 51 allows the water tank 5 to accommodate taller and larger storage boxes 6, so as to store more garbage and reduce the workload of the staff in cleaning up the garbage. The two opposite side walls of the storage box 6 along the length of the rotation axis 2 are respectively connected to the two opposite side walls of the flow channel 51, which can maximize the absorption of garbage peeled off from the arc-shaped rod 31 by the cleaning rod 4, and prevent garbage from scattering due to the small size of the storage box 6 and the mismatch between the size of the trash rack, which would affect the operation of the downstream water turbine.
[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the storage tank 6 protrudes from the water surface on the side away from the debris-blocking paddle 3 to form a debris-blocking plate 61. The side of the storage tank 6 closest to the debris-blocking grid of the power station is lower than part of the debris-blocking paddle 3 to facilitate the falling of debris on the debris-blocking paddle 3 into the storage tank 6.
[0047] In addition, a comb plate 62 is installed on the upper end of the storage tank 6 near the side of the debris-blocking paddle 3, and the side of the spiral rod 41 away from the rotating shaft 2 overlaps the comb plate 62 to restrict the spiral rod 41 from rotating with the water flow.
[0048] Specifically, the two sides of the debris baffle 61 are fixedly connected to the two sides of the water tank 5 to prevent garbage from drifting over the storage tank 6 and affecting the operation of the water turbine; the comb plate 62 is inclined from bottom to top towards the direction of the screw rod 41 to facilitate the overlap of the screw rod 41. In addition to restricting the screw rod 41 from rotating with the water flow, the comb plate 62 also facilitates the flow of water in the storage tank 6 into the flow channel 51 through the comb plate 62, reducing the water flow pressure on the comb plate 62 and thus extending its service life.
[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the energy storage power station also includes an installation groove 7, which is located on one side of the water tank 5. A drive assembly 1 is installed in the installation groove 7, and one end of the rotating shaft 2 extends into the installation groove 7 and is driven by the drive assembly 1.
[0050] In this embodiment, the drive component 1 is completely isolated from the water tank 5 to prevent the water in the water tank 5 from affecting the operation of the drive component 1, making it easier to operate the drive component 1 and improving its service life. In addition, the drive component 1 drives the rotating shaft 2 to rotate, making the rotation speed of the trash rack controllable. In actual operation, the rotation speed of the trash rack can be adjusted according to factors such as the amount of trash and water flow to ensure that the trash rack achieves the best interception effect and improves the flexibility of the trash rack.
[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the drive assembly 1 includes a motor 11, a first sprocket 12, a chain 13, and a second sprocket 14. The output shaft of the motor 11 is fixedly connected to the first sprocket 12, and the second sprocket 14 is fixedly connected to one end of the rotating shaft 2. The first sprocket 12 and the second sprocket 14 rotate synchronously through the chain 13. The diameter of the first sprocket 12 is smaller than the diameter of the second sprocket 14.
[0052] Specifically, the side wall of the mounting groove 7 is provided with a receiving groove, which provides an installation position for the motor 11, thereby reserving more space for the first sprocket 12 and the second sprocket 14 in the mounting groove 7, so that the first sprocket 12 and the second sprocket 14 can be set facing each other in the vertical direction, and thus facilitate the two to maintain synchronous rotation through the sprockets; since the motor 11 rotates too fast, the diameter of the first sprocket 12 is smaller than the diameter of the second sprocket 14, which makes it easier to reduce the rotation speed of the second sprocket 14, thereby reducing the rotation speed of the rotating shaft 2, and thus ensuring the normal operation of the trash rack.
[0053] The trash rack in this application is used in the following exemplary process:
[0054] When motor 11 is turned on, motor 11 drives the first sprocket 12 to rotate, and the second sprocket 14 rotates synchronously through chain 13. The second sprocket 14 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the arc rod 31 to rotate. While the arc rod 31 rotates, the spiral rod 41 peels off the garbage on the rotating rod, and the garbage enters the storage box 6 for storage.
