Description

Technical Field

[0001] This invention relates to the field of hydropower station cleaning technology, and in particular to a rotary cleaning device for fixed trash racks in hydropower stations. Background Technology

[0002] A hydropower station typically has a water guide mechanism, spiral casing, water diversion tunnel / pressure steel pipe, working gate, maintenance gate, and trash rack installed sequentially on the front side of the turbine. The trash rack can block natural waste, domestic garbage and plastic products, construction or industrial waste, etc., to ensure power generation efficiency, equipment safety and maintain power grid stability.

[0003] When trash racks are used for a long time, floating debris will clog the racks, reducing the water flow area and increasing head loss. This may disrupt the balance between power supply and demand and result in power loss. At the same time, decaying animal carcasses and organic waste will consume oxygen in the water, causing water quality deterioration and odor spread, which will affect the surrounding landscape and ecology. Therefore, it is necessary to clean the floating debris at the trash racks intermittently to keep the water flow of floating debris stable and to keep the trash racks clean.

[0004] Currently, common cleaning structures on trash racks generally include conveyor belts, scraper shafts, and toothed scraper plates. The toothed scraper plates scrape away floating debris accumulated on the trash rack, and then the conveyor belt, scraper shaft, and toothed scraper plates transport the debris. However, with this cleaning structure, floating debris naturally approaches the scraper shaft and toothed scraper plates. When the scraper shaft and toothed scraper plates lift the debris off the water surface for collection, it easily detaches from the scraper shaft and toothed scraper plates due to the water flow, resulting in low collection efficiency. Simultaneously, floating debris easily gets caught on the scraper shaft and toothed scraper plates, and after being circumferentially transported by the conveyor belt, the scraper shaft and toothed scraper plates carry the debris back into the water, also leading to low collection efficiency. Furthermore, this structure is difficult to apply to hydropower stations. With the conveyor belt transporting the scraper shaft and toothed scraper plates circumferentially, the scraper shaft and toothed scraper plates can easily carry floating debris to the side of the trash rack near the maintenance gate, causing some of the debris to enter the hydropower station's power generation system, affecting normal power generation and the system's lifespan. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rotary cleaning device for fixed trash racks in hydropower stations, which solves the problem that floating debris easily gets caught on the scraper shaft and scraper blades, and then, after being driven circumferentially by the conveyor belt, the scraper shaft and scraper blades will carry the floating debris back into the water, resulting in low efficiency in cleaning and collecting floating debris.

[0006] To achieve the above objectives, the basic solution of the present invention is as follows: A rotary cleaning device for a fixed trash rack in a hydropower station, comprising a trash rack body and a cleaning unit attached to the side of the trash rack body away from the maintenance gate, the cleaning unit comprising:

[0007] The scraper is set vertically, and one side of the scraper slides in contact with the surface of the garbage rack body;

[0008] A horizontal sliding assembly that drives the scraper to move along the horizontal direction of the trash rack body is installed on the top side of the trash rack body;

[0009] Also includes:

[0010] A collection and compression assembly for collecting and compressing floating debris is installed vertically on one side of the vertical side of the debris rack body, with the vertical sidewall of the scraper facing the collection and compression assembly.

[0011] The technical principle of this invention is as follows: When cleaning the floating debris accumulated on the body of the baffle, the horizontal sliding component drives the scraper to move horizontally along the surface of the baffle body. The scraper can scrape off the floating debris on the surface of the baffle body and push the floating debris towards the collection and compression component. The collection and compression component can collect the floating debris, reducing the amount of floating debris scattered along the water flow during the collection process. At the same time, when a large amount of floating debris is collected in the collection and compression component, the collection and compression component compresses the floating debris, which facilitates the collection, bagging and transportation of the floating debris. The collection and processing of floating debris is more streamlined and reliable, improving the collection and processing efficiency.

[0012] Furthermore, the collection and compression components include:

[0013] The collecting cylinder has a vertical axis and is open at both ends. A slag inlet hole is provided on the side wall of the collecting cylinder, extending through the upper end of the cylinder. The slag inlet hole is directly opposite the side wall of the scraper, and the side wall of the scraper can abut against the outer wall of the collecting cylinder. An arc-shaped groove is coaxially arranged at the upper end of the collecting cylinder, located near the maintenance gate, and extending through the upper end of the collecting cylinder. The central angle occupied by the cross-sectional profile of the arc-shaped groove is greater than or equal to 180° and less than 190°. A water outlet hole is provided on the side wall of the collecting cylinder.

[0014] The extrusion base plate is coaxially and slidably installed inside the lower end of the collecting cylinder;

[0015] The top extrusion plate is horizontally snapped onto the upper end of the collecting cylinder, with the top extrusion plate directly opposite the bottom extrusion plate.

[0016] Several pull ropes are provided, and a connecting groove is vertically provided on the side wall of the collecting cylinder for the pull ropes to pass through. After the lower end of the pull rope passes through the connecting groove, it is fixedly connected to the edge of the extrusion base plate.

[0017] The winding roller has its axis set horizontally, and the upper end of the pull rope is fixedly connected to the outer wall of the winding roller.

[0018] The arc-shaped baffle can block and cover the slag inlet hole of the collection cylinder.

[0019] With the above setup, when collecting and compressing floating debris, first, the arc-shaped baffle at the slag inlet is moved to expose the slag inlet. Then, the scraper pushes the floating debris through the slag inlet into the collection cylinder, efficiently and quickly pushing the floating debris accumulated on the surface of the slag rack into the collection cylinder. When a large amount of floating debris accumulates in the collection cylinder, the arc-shaped baffle is reinstalled to cover the slag inlet. The winding roller is then rotated, winding the pull rope. At this time, the pull rope pulls the compression bottom plate upwards. When the floating debris is compressed to the compression top plate, the compression bottom plate and compression top plate compress and tighten the floating debris, simultaneously driving the floating debris... The entire object is moved upwards to the arc-shaped groove. When the thickness of the compressed floating object is greater than the vertical distance between the bottom surface of the arc-shaped groove and the lower surface of the extrusion plate, the extrusion plate is removed horizontally. The extrusion plate continues to push the compressed floating object upwards, allowing the compressed floating object to be quickly transferred to the dam body. When the thickness of the compressed floating object is less than the vertical distance between the bottom surface of the arc-shaped groove and the lower surface of the extrusion plate, the compressed floating object can be removed horizontally through the arc-shaped groove, further enabling the compressed floating object to be quickly transferred to the dam body. Through the above process, the compressed floating object can be quickly bagged, making the bagging and transfer of the floating object more convenient.

[0020] Furthermore, the water outlet is located on the side of the collection cylinder away from the slag inlet.

[0021] With the above settings, when the scraper pushes the floating objects into the collection cylinder, the water flows out from the outlet hole, reducing the amount of water overflowing from the slag inlet hole and reducing the amount of floating objects flowing out from the slag inlet hole, making it easier for the floating objects to enter the collection cylinder stably.

[0022] Furthermore, an arc-shaped mounting groove for receiving an arc-shaped baffle is coaxially provided on one side of the slag inlet hole of the collecting cylinder, and a limiting groove for embedding the end of the arc-shaped baffle is provided on the other side of the slag inlet hole of the collecting cylinder.

[0023] The collection and compression components also include:

[0024] lever;

[0025] The connecting sliding component has an arc-shaped cross-sectional profile. The collecting cylinder has a groove for the connecting sliding component to rotate circumferentially and coaxially. One end of the connecting sliding component is fixedly connected to the end of the arc-shaped baffle away from the limiting groove. The other end of the connecting sliding component passes through the collecting cylinder and is located at the bottom surface of the arc-shaped groove in the collecting cylinder. The lever is vertically fixedly installed at the end of the connecting sliding component near the arc-shaped groove.

[0026] With the above settings, when controlling the overlap between the arc-shaped baffle and the slag inlet hole, hold the lever and push it to slide along the groove. The lever pulls the connecting sliding component to rotate clockwise or counterclockwise relative to the collection cylinder. The connecting sliding component drives the arc-shaped baffle to rotate along the arc-shaped mounting groove, so that the arc-shaped baffle is blocked or exposed at the slag inlet hole, which is convenient to adapt to the timing of floating objects entering the slag inlet hole. In the above process, the lever can cooperate with the connecting sliding component, and thus the relative position of the arc-shaped baffle and the slag inlet hole can be controlled from the arc-shaped groove, making the position control of the arc-shaped baffle more convenient and reliable.

[0027] Furthermore, several filter holes are horizontally penetrating the curved baffle.

[0028] With the above settings, when the top and bottom plates compress the floating objects, the arc-shaped baffle can both limit and block the floating objects, and allow the water between the floating objects to be quickly discharged through the filter holes, thereby improving the compression efficiency of the floating objects.

[0029] Furthermore, the end of the scraper away from the main body of the sludge rack is an arc-shaped plate extending towards the slag inlet hole.

[0030] The above design facilitates the fit between the end of the scraper and the outer wall of the collection cylinder, allowing the scraper to push floating objects into the collection cylinder. At the same time, as the scraper moves toward the collection cylinder, the arc-shaped plate of the scraper can fully limit the floating objects, reducing the amount of floating objects that drift and disperse along the water flow during the pushing process.

[0031] Furthermore, the horizontal sliding component includes:

[0032] The sliding rail is horizontally and fixedly installed on the side of the trash rack body near the maintenance gate;

[0033] The slider is rectangular and slides in conjunction with the sliding rail. A sliding groove is provided on the top side of the sludge rack body for the slider to slide horizontally. The slider slides in contact with the bottom surface of the sliding groove of the sludge rack body. The upper end of the scraper is fixedly connected to the end of the slider away from the sliding rail.

[0034] The cleaning unit also includes:

[0035] A rotating shaft is vertically positioned, with its upper end rotatably connected to the end of the slider furthest from the slide rail.

[0036] Several elastic bristles that can contact the surface of the waste rack body are fixedly installed on the circumferential surface of the rotating shaft.

[0037] The first motor that drives the rotating shaft to rotate is fixedly mounted on the upper surface of the slider.

[0038] With the above settings, when the scraper moves laterally, the control slider slides horizontally along the sliding rail, and the first motor starts synchronously. The slider moves horizontally stably under the support of the moving slot on the main body of the sluice gate. The front end of the slider drives the scraper, the rotating shaft, and the first motor to move horizontally synchronously. The first motor drives the rotating shaft to rotate, and the rotating shaft drives the elastic bristles to rotate. Under the action of centrifugal force, the elastic bristles are in an inclined state in contact with the surface of the sluice gate, cleaning the floating objects adhering to the surface of the sluice gate, so that the floating objects can be removed from the surface of the sluice gate as much as possible. The floating objects can be limited by the scraper and the arc-shaped end of the scraper. At the same time, the slider, the sluice gate, and the sliding rail can stably guide the horizontal movement of the scraper, the rotating shaft, and the first motor. The cooperation of the rotating shaft and the elastic bristles can clean the floating objects adhering to the surface of the sluice gate more thoroughly, and can push the floating objects accumulated on the surface area of ​​the sluice gate more thoroughly into the collection cylinder.

[0039] Furthermore, an ear plate that can be embedded into a connecting groove is fixedly provided at the edge of the extrusion base plate, and the ear plate of the extrusion base plate is fixedly connected to the pull rope; several pull ropes are evenly arranged around the circumference of the collection cylinder.

[0040] With the above configuration, the ear plate can slide and engage with the connecting groove, allowing the extrusion base plate to move stably up and down along the connecting groove under the traction of the pull rope. The pull rope can provide a stable pulling force for the extrusion base plate. During the process of the pull rope pulling the extrusion base plate up and down, the extrusion top plate can also limit the pull rope's interaction up and down along the connecting groove.

[0041] Furthermore, a cover is installed at the water outlet of the collection cylinder, and a water pump is connected to the water pump.

[0042] With the above setup, while pushing the floating debris into the collection cylinder, the water pump is started. The negative pressure is transmitted to the water outlet through the water pumping pipe, thereby drawing water from the collection cylinder. This allows the floating debris at the slag inlet of the collection cylinder to move into the collection cylinder under the action of the water flow, improving the collection efficiency of the floating debris.

[0043] Furthermore, the surface of the arc-shaped baffle near the limiting groove is wedge-shaped.

[0044] With the above settings, when the arc-shaped baffle closes the slag inlet hole, the wedge-shaped end of the arc-shaped baffle can be quickly embedded into the limiting groove, making the limiting installation of the arc-shaped baffle reliable and easy to adjust. Attached Figure Description

The axis of the collection cylinder 40 is vertically arranged. The second motor 506 is fixedly installed on the upper side of the dam body 10. Both ends of the collection cylinder 40 are open, and the lower end of the collection cylinder 40 is lower than... On the lower side of the sludge rack body 20, the side wall of the collection cylinder 40 is provided with a slag inlet hole 401 that communicates with the collection cylinder 40. The lower inner wall of the slag inlet hole 401 is lower than the lower side of the scraper 301. At the same time, the slag inlet hole 401 penetrates the upper end of the collection cylinder 40. The slag inlet hole 401 is directly opposite the side wall of the scraper 301, and the side wall of the scraper 301 can abut against the outer wall of the collection cylinder 40. The front end of the scraper 301 is an arc-shaped plate extending towards the slag inlet hole 401.

[0056] like Figure 3 and Figure 4 As shown, an arc-shaped groove 402 is coaxially provided at the upper end of the collecting cylinder 40. The arc-shaped groove 402 is located on the side near the maintenance gate and penetrates through the upper end of the collecting cylinder 40. The central angle occupied by the cross-sectional profile of the arc-shaped groove 402 is greater than or equal to 180°. Figure 1 and Figure 2 As shown, a water outlet 408 is provided on the left front side wall of the collecting cylinder 40; the extrusion base plate 501 is coaxially and slidably installed in the lower end of the collecting cylinder 40; a semi-circular annular groove 403 is provided at the top of the collecting cylinder 40 for the extrusion top plate 503 to be horizontally embedded, the semi-circular annular groove 403 and the arc groove 402 are horizontally aligned, so that the extrusion top plate 503 can be horizontally snapped onto the upper end of the collecting cylinder 40, and the extrusion top plate 503 and the extrusion base plate 501 are aligned; at the same time, as Figure 4 As shown, a connecting groove 404 for the pull rope 504 to pass through is vertically provided on the side wall of the collecting cylinder 40. The lower end of the pull rope 504 passes through the connecting groove 404 and is fixedly connected to the edge of the extrusion base plate 501. The axis of the winding roller 505 is horizontally arranged, and the winding roller 505 is directly opposite the upper end of the collecting cylinder 40. The upper end of the pull rope 504 is fixedly connected to the outer wall of the winding roller 505. An ear plate 502 that can be embedded in the connecting groove 404 is fixedly provided at the edge of the extrusion base plate. The ear plate 502 slides in contact with the inner wall of the connecting groove 404. The ear plate 502 of the extrusion base plate 501 is fixedly connected to the pull rope 504. The two sets of pull ropes 504 are evenly arranged around the circumference of the collecting cylinder 40.

[0057] like Figure 4 As shown, the arc-shaped baffle 508 can block and cover the slag inlet hole 401 of the collecting cylinder 40, and several filter holes 518 are horizontally penetrating the arc-shaped baffle 508; an arc-shaped mounting groove 405 for receiving the arc-shaped baffle 508 is coaxially provided on the right side of the slag inlet hole 401 of the collecting cylinder 40, and a limiting groove 406 for the end of the arc-shaped baffle 508 to be embedded in the other side of the slag inlet hole 401 of the collecting cylinder 40; the right end surface of the arc-shaped baffle 508 is wedge-shaped; connecting The cross-sectional profile of the sliding member 509 is arc-shaped. The collection cylinder 40 is provided with a groove 407 for the connecting sliding member 509 to rotate circumferentially and coaxially. One end of the connecting sliding member 509 is fixedly connected to the end of the arc-shaped baffle 508 away from the limiting groove 406. The other end of the connecting sliding member 509 passes through the collection cylinder 40 and is located at the bottom surface of the arc-shaped groove 402 of the collection cylinder 40. The lever 507 is vertically fixedly installed at the end of the connecting sliding member 509 near the arc-shaped groove 402.

[0058] In addition, such as Figure 1 As shown, a water outlet 408 of the collection cylinder 40 is covered with a water pump 60, which is connected to a water pump.

[0059] In this embodiment, a rotary cleaning device for a fixed trash rack in a hydropower station is used as follows: Figure 4 As shown, hold the lever 507 and push the lever 507 to slide to the left along the slide groove 407. The lever 507 pulls the connecting sliding part 509 to rotate to the left. The connecting sliding part 509 drives the arc-shaped baffle 508 to rotate along the arc-shaped mounting groove 405, so that the slag inlet hole 401 is exposed.

[0060] Then, the slider 303 is controlled to slide horizontally along the sliding rail 302, and the first motor 306 starts synchronously. The slider 303 moves horizontally stably under the support of the moving through groove 201 on the screen body 20. The front end of the slider 303 drives the scraper 301, the rotating shaft 304 and the first motor 306 to move horizontally synchronously. The first motor 306 drives the rotating shaft 304 to rotate, and the rotating shaft 304 drives the elastic bristles 305 to rotate. Under the action of centrifugal force, the elastic bristles 305 are in an inclined state in contact with the surface of the screen body 20, cleaning the floating objects adhering to the surface of the screen body 20, so that the floating objects can be removed from the surface of the screen body 20 as much as possible. At the same time, the floating objects can be limited by the scraper 301 and the arc-shaped plate end of the scraper 301. As the scraper 301 moves towards the side close to the slag inlet hole 401, the scraper 301 pushes the floating objects into the collection cylinder 40 through the slag inlet hole 401. Repeat this process to clean the surface of the screen body 20. The floating debris accumulated on the surface is efficiently and quickly pushed into the collection cylinder 40. During the process of pushing the floating debris into the collection cylinder 40, the slider 303, the baffle body 20, and the sliding rail 302 can stably guide the horizontal movement of the scraper 301, the rotating shaft 304, and the first motor 306. The cooperation between the rotating shaft 304 and the elastic bristles 305 can thoroughly clean the floating debris adhering to the surface of the baffle body 20. At the same time, the arc-shaped plate end of the scraper 301 can... The floating objects are fully restrained to reduce the amount of floating objects that drift and disperse along the water flow during the pressing process; the rotating shaft 304 and the scraper 301 vertically cover the surface of the screen body 20 from bottom to top, which comprehensively pushes the floating objects accumulated on the surface area of ​​the screen body 20 into the collection cylinder 40, and can also push the floating objects floating on the liquid surface at the same time, which can effectively improve the cleaning efficiency of floating objects and allow the surface of the screen body 20 to be quickly exposed, reducing the impact on the subsequent power generation process.

[0061] At the same time, the water pump is started, and the negative pressure is transmitted to the water outlet 408 through the water pumping pipe 60, thereby drawing water into the collection cylinder 40. This allows the floating objects at the slag inlet 401 of the collection cylinder 40 to move into the collection cylinder 40 under the action of the water flow, thus improving the collection efficiency of the floating objects.

[0062] When a large amount of floating matter accumulates in the collection cylinder 40, hold the lever 507 again and push it to slide to the right along the slide groove 407. The lever 507 pulls the connecting sliding member 509 to rotate to the right. The connecting sliding member 509 drives the arc-shaped baffle 508 to rotate along the arc-shaped mounting groove 405, so that the slag inlet hole 401 is covered by the arc-shaped baffle 508. Start the second motor, which drives the winding roller 505 to rotate in the forward direction. The winding roller 505 winds up the two sets of pull ropes 504. At this time, the pull ropes 504 drive the extrusion bottom plate 501 to move upward through the ear plate 502. The extrusion bottom plate 501 pushes the floating matter in the collection cylinder 40 to move upward along the connecting groove 404. When the floating matter is squeezed to the extrusion top plate 503, the extrusion bottom plate 501 and the extrusion top plate 503 squeeze the floating matter. The compressed material is simultaneously moved upwards to the arc-shaped groove 402. When the thickness of the compressed material is greater than the vertical distance between the bottom surface of the arc-shaped groove 402 and the lower surface of the extrusion plate 501, the extrusion plate 503 is horizontally removed along the semi-circular groove 403. The extrusion plate 503 continues to push the compressed material upwards, allowing the compressed material to be quickly transferred to the dam body 10. When the thickness of the compressed material is less than the vertical distance between the bottom surface of the arc-shaped groove 402 and the lower surface of the extrusion plate 501, the compressed material can be horizontally removed through the arc-shaped groove 402, further enabling the compressed material to be quickly transferred to the dam body 10. Through the above process, the compressed material can be quickly bagged, making the bagging and transfer of the material more convenient.

[0063] After the single floating debris is lifted and compressed, the above process can be repeated to continuously clean, collect and transfer the floating debris, making the handling of floating debris efficient and orderly, and ensuring the normal power generation of the hydropower station's power generation system.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
