Description

Technical Field

[0001] The present invention relates to the technical field of river flood control and waterproofing, and in particular to a waterproof structure for a pumped storage power station. Background Art

[0002] Waterproof wall is a concrete or masonry water retaining structure used to ensure flood control safety or other special requirements in towns and important industrial and mining enterprises, along rivers and coastal areas. It is also called flood control wall. The function of flood control wall is the same as that of dike. Because there are important traffic arteries and dense buildings along the river in the city, sometimes due to the limitation of existing projects, the needs of urban planning and development, or the limitation of soil resources, flood control wall is used to reduce land occupation and demolition.

[0003] However, most current pumped-storage power station waterproofing structures are unable to automatically erect the waterproof wall, requiring manual labor to move sand and gravel. This not only wastes manpower and material resources, but is also inefficient and unsuitable for widespread promotion. Furthermore, during use, a significant amount of time and effort is required for subsequent maintenance. Some waterproofing structures that can automatically erect are used for temporary use, but if not used promptly, they will not achieve the desired waterproofing effect. Furthermore, the transmission mechanism used to erect the waterproof structure needs to be immersed in water during waterproofing, shortening its service life. Furthermore, the waterproof wall has poor sealing properties. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a waterproof structure for a pumped storage power station which can automatically flip up to achieve timely waterproofing and can adjust the flood control height.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A waterproof structure for a pumped-storage power station includes a concrete edge barrier, a turntable, a waterproof wall and a linkage mechanism. A water collection trough is provided on the top of the concrete edge barrier, and the turntable can be rotatably arranged in the water collection trough. A plurality of mounting rods are provided on the circumference of the turntable and are evenly spaced around the central axis of the turntable. Each mounting rod is hinged with a barrel body for rotating the turntable after filling water. A flip column is provided below the turntable for flipping the lowest barrel body to pour out water during the rotation of the turntable. The waterproof wall includes a hinged wall body and a telescopic wall body. The hinged wall body can be flipped and hinged to the top of the concrete edge barrier and is located on the outside of the water collection trough. The telescopic wall body can be telescopically arranged on the hinged wall body. The turntable is connected to the telescopic wall through a linkage mechanism, so that the waterproof wall can be flipped up to prevent water.

[0007] As a further improvement of the above technical solution:

[0008] The linkage mechanism includes a push rod, a lifting screw, a transmission shaft, a gear pair and a lifting transmission member for driving the lifting screw to rise and fall. The transmission shaft and the lifting transmission member are both rotatably arranged in the concrete edge protection. One end of the transmission shaft is linked to the turntable through the gear pair, and the other end is linked to the lifting transmission member. One end of the push rod is hinged to the top end of the lifting screw, and the other end is hinged to the telescopic wall.

[0009] The lifting transmission member is a first helical gear, the lifting screw rod is passed through the center of the first helical gear and is threadedly connected to the first helical gear, a second helical gear is provided on the transmission shaft, and the first helical gear is meshed with the second helical gear.

[0010] The gear pair includes a third helical gear and a fourth helical gear meshing with each other, the third helical gear is arranged on the transmission shaft, and the fourth helical gear is fixed on the turntable and is coaxial with the turntable.

[0011] A hinged rod is fixed on one side of the hinged wall, a support rod is fixed on one side of the telescopic wall, one end of the hinged rod away from the hinged wall is hinged on the concrete edge protection, and the push rod is hinged to the middle of the support rod.

[0012] A lifting column is provided on the top of the concrete edge protection, and the hinged rod is hinged to the lifting column.

[0013] The concrete edge barrier is provided with a pressing surface between the lifting column and the water collecting trough. When the waterproof wall is turned over, the bottom of the hinged wall body presses against the pressing surface.

[0014] A sealing gasket is provided on the abutting surface.

[0015] The concrete edge protection is provided with a cover plate above the water collecting tank, and the cover plate is provided with a water inlet, and the water inlet is located obliquely above the water collecting tank.

[0016] A water retaining plate is provided at the bottom of the cover plate.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] The present invention provides a waterproof structure for a pumped storage power station. When waterproofing is not carried out, the waterproof wall is in a downward-turned horizontal state, which does not affect the landscape on both sides of the river channel. When flooding arrives and waterproofing is required, the flood first flows from the river channel into the sump to fill the barrel body on the turntable close to the river channel. The filled barrel body drives the turntable to rotate under the action of gravity. When the barrel body rotates to the bottom, it is blocked by the turning column and flipped to pour out the water, so that the barrel body on the turntable close to the river channel has water, and the barrel body on the side away from the river channel has no water, so that a gravity difference is formed on both sides of the turntable. The turntable rotates and operates under the action of the gravity difference on both sides. During the rotation process, the turntable drives the waterproof wall to flip up to a vertical state through a linkage mechanism to prevent water in the river channel from flowing out of the river channel. Furthermore, because the waterproof wall comprises an articulated wall body and a telescopic wall body, the articulated wall body is hingedly connected to the top of the concrete edge barrier and positioned outside the sump, and the telescopic wall body is telescopically mounted on the articulated wall body. In other words, the waterproof wall is retractable. When the flood is small, the turntable flips the waterproof wall upward via a linkage mechanism, placing the telescopic wall body in a low position. When the flood is large, the turntable flips the waterproof wall upward via a linkage mechanism and lifts the telescopic wall body until the telescopic wall body extends upward to a high position, thereby increasing the flood control height. When a flood approaches, the waterproof wall of this pumped-storage power station waterproof structure automatically flips upward under the action of the gravity of the flood water, achieving timely waterproofing. Furthermore, the waterproof wall is retractable to adjust the flood control height. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 and Figure 2 An embodiment of the waterproof structure for a pumped-storage power station of the present invention is shown. The waterproof structure for a pumped-storage power station includes a concrete edge 1, a turntable 2, a waterproof wall 3 and a linkage mechanism 4. A water collecting trough 5 is provided on the top of the concrete edge 1. The turntable 2 can be rotatably arranged in the water collecting trough 5. A plurality of mounting rods 21 are provided on the circumference of the turntable 2 and are evenly spaced around the central axis of the turntable 2. Each mounting rod 21 is hinged with a barrel body 22 for rotating the turntable 2 after filling water. A flip column 23 is provided below the turntable 2 for flipping the lowest barrel body 22 to pour out water during the rotation of the turntable 2. The waterproof wall 3 includes a hinged wall body 33 and a telescopic wall body 34. The hinged wall 33 can be flipped and hinged to the top of the concrete edge 1 and is located on the outside of the water collecting trough 5. The telescopic wall body 34 can be telescopically arranged on the hinged wall body 33. The turntable 2 is connected to the telescopic wall 34 through the linkage mechanism 4, so that the waterproof wall 3 can be flipped up to prevent water. Specifically, the concrete edge 1 is set on the side of the river, the outer side of the water collection tank 5 is the side away from the river, the upper end of the water collection tank 5 is open for flooding, and the upper end of the barrel 22 is open for flooding. Figure 1 As shown, the waterproof wall 3 is in a horizontal state with a downward turn, which does not affect the landscape on both sides of the river. When floods come and waterproofing is required, as shown in FIG. Figure 2 As shown, the flood first flows from the river channel into the sump 5 to fill the barrel body 22 on the turntable 2 close to the river channel. The filled barrel body 22 drives the turntable 2 to rotate under the action of gravity. When the barrel body 22 rotates to the bottom, it is blocked by the flip column 23 to flip over to pour out the water, so that the barrel body 22 on the turntable 2 close to the river channel has water, and the barrel body 22 on the side away from the river channel has no water, so that a gravity difference is formed on both sides of the turntable 2. The turntable 2 rotates under the action of the gravity difference on both sides. During the rotation process, the turntable 2 drives the waterproof wall 3 to flip up to a vertical state through the linkage mechanism 4 to prevent the water in the river channel from flowing out of the river channel. Furthermore, since the waterproof wall 3 includes an articulated wall 33 and a telescopic wall 34, the articulated wall 33 is hingedly connected to the top of the concrete edge 1 and positioned outside the sump 5, and the telescopic wall 34 is telescopically mounted on the articulated wall 33. In other words, the waterproof wall 3 is telescopic. When the flood is small, the turntable 2, via the linkage mechanism 4, flips the waterproof wall 3 upward, placing the telescopic wall 34 in a low position. When the flood is large, the turntable 2, via the linkage mechanism 4, flips the waterproof wall 3 upward and lifts the telescopic wall 34 until the telescopic wall 34 extends upward to a high position, thereby increasing the flood control height. When a flood arrives, the pumped-storage power station waterproof structure automatically flips the waterproof wall 3 upward under the action of the gravity of the flood to achieve timely waterproofing. Furthermore, the waterproof wall 3 is telescopic to adjust the flood control height.

[0025] Specifically, the hinged wall 33 is provided with a telescopic guide slot 35, and one end of the telescopic wall 34 is movably inserted into the guide slot 35, allowing the telescopic wall 34 to slide within the guide slot 35 to achieve a telescopic function. When the telescopic wall 34 is slid away from the guide slot 35 (i.e., sliding out of the guide slot 35), the flood control height of the waterproof wall 3 is raised. When the telescopic wall 34 is slid toward the guide slot 35 (i.e., sliding into the guide slot 35), the flood control height of the waterproof wall 3 is lowered.

[0026] In this embodiment, the linkage mechanism 4 includes a push rod 41, a lifting screw 42, a transmission shaft 43, a gear pair 44, and a lifting transmission member 45 for driving the lifting screw 42 up and down. The transmission shaft 43 and the lifting transmission member 45 are both rotatably disposed in the concrete edge protection 1. One end of the transmission shaft 43 is linked to the turntable 2 via the gear pair 44, and the other end is linked to the lifting transmission member 45. One end of the push rod 41 is hinged to the top of the lifting screw 42, and the other end is hinged to the telescopic wall 34. The rotation of the turntable 2 drives the transmission shaft 43 through the gear pair 44, which in turn drives the lifting transmission member 45 to rotate. The lifting transmission member 45 drives the lifting screw 42 up and down. The lifting screw 42 causes the waterproof wall 3 to flip up and down through the push rod 41.

[0027] In this embodiment, the lifting transmission member 45 is a first helical gear. The lifting screw 42 is disposed through the center of the first helical gear and is threadedly connected to the first helical gear. The transmission shaft 43 is provided with a second helical gear 46, which meshes with the first helical gear 46. Because the lifting screw 42 is disposed through the center of the first helical gear and is threadedly connected to the first helical gear, the rotation of the first helical gear can drive the lifting screw 42 up and down. Moreover, when the lifting screw 42 is subjected to downward pressure, a reverse locking force is generated between the lifting screw 42 and the first helical gear, preventing the lifting screw 42 from descending under the downward pressure. Thus, when the turntable 2 is stationary, the waterproof wall 3 is maintained in the upward, waterproof state.

[0028] In this embodiment, the gear pair 44 includes a third helical gear 47 and a fourth helical gear 48 that mesh with each other. The third helical gear 47 is mounted on the transmission shaft 43, while the fourth helical gear 48 is fixed to and coaxial with the turntable 2. The turntable 2 and the transmission shaft 43 are linked by the third and fourth helical gears 47 and 48, ensuring smooth transmission. The transmission shaft 43, the lifting transmission member 45, and the first and second helical gears 46 are all located within the concrete edge protection 1, preventing the linkage mechanism 4 from being completely submerged in water and thus increasing its service life. Furthermore, the linkage mechanism 4 is concealed, minimizing its exposure and space occupation.

[0029] In this embodiment, a hinged rod 31 is fixed to one side of the hinged wall 33, and a support rod 32 is fixed to one side of the telescopic wall 34. The end of the hinged rod 31, distal to the hinged wall 33, is hinged to the concrete edge barrier 1, and a push rod 41 is hinged to the middle of the support rod 32. Specifically, a raised column 11 is provided at the top of the concrete edge barrier 1, and the end of the hinged rod 31, distal to the hinged wall 33, is hinged to the raised column 11. When not waterproofing, the waterproof wall 3 is supported on the top of the concrete edge barrier 1 by the hinged rod 31 and the support rod 32. It is best to keep the waterproof wall 3 in a horizontal position to improve the aesthetics.

[0030] In this embodiment, the concrete edge 1 is provided with a pressing surface 12 between the lifting column 11 and the water collecting trough 5. When the waterproof wall 3 is flipped up, the bottom of the hinged wall 33 is pressed against the pressing surface 12, thereby limiting the flipping of the waterproof wall 3 and achieving a better waterproof effect.

[0031] In this embodiment, a sealing gasket 121 is provided on the abutting surface 12 to ensure that the bottom of the hinged wall 33 is in sealing contact with the abutting surface 12, thereby preventing water leakage and improving the waterproof effect.

[0032] In this embodiment, the concrete edge barrier 1 is provided with a cover plate 6 above the sump 5. The cover plate 6 is provided with a water inlet 61, which is located diagonally above the sump 5. Specifically, when not waterproofed, the waterproof wall 3, in its downward position, is flush with the cover plate 6, creating an aesthetically pleasing appearance and allowing for use as a sidewalk. The water inlet 61 is located diagonally above the sump 5. A diversion slope is provided on the side of the sump 5 near the water inlet 61. Floodwater flows from the water inlet 61 under the cover plate 6, then along the diversion slope into the sump 5, filling the barrel 22 of the turntable 2 near the diversion slope, causing the turntable 2 to rotate.

[0033] In this embodiment, a water baffle 62 is provided at the bottom of the cover plate 6. The top of the water baffle 62 is fixedly connected to the cover plate 6, and the bottom of the water baffle 62 extends to the upper middle portion of the turntable 2, and is used to prevent water from entering the side of the turntable 2 away from the diversion slope when the water inflow is too large. The water capacity of the water collection tank 5 can be designed so that when the waterproof wall 3 is flipped up to a vertical state, part of the barrel body 22 or the entire barrel body 22 is immersed in the water in the water collection tank 5, so that the gravity difference on both sides of the turntable 2 is very small or zero, so that the turntable 2 has no upward flipping force on the upright waterproof wall 3 or has a very small upward flipping force, thereby reducing the force acting on the linkage mechanism 4 during waterproofing, thereby improving the service life.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
