Description

Technical Field

[0001] The invention relates to the technical field of dam slope reinforcement, in particular to a dam slope reinforcement device for a pumped storage power station. Background Art

[0002] A pumped storage power station is a power facility that uses water as an energy storage medium and realizes the storage and management of electric energy through the mutual conversion of electric energy and potential energy. When the power load is low, the excess electric energy is used to pump water from the lower reservoir to the upper reservoir and store it as potential energy; when the power load is high, the water in the upper reservoir is released to the lower reservoir, and the potential energy is converted back into electric energy through the turbine to supply the power grid. This method can balance the load fluctuations of the power grid and improve the stability and economy of the power grid. During the construction of the pumped storage power station, the dam slopes on both sides of the river need to be reinforced to prevent the collapse of the pumped storage power station due to the loss of water and soil.

[0003] At present, when reinforcing the dam slope, it is usually firstly to use a pile driver to drive the anchor rod into the soil to fix the anchor rod, then pour concrete into the soil through the anchor rod to form a cement column, and finally pour concrete on the dam slope, so that the concrete on the dam slope and the concrete in the soil become a whole, thereby realizing the reinforcement of the dam slope. However, since the diameter of the anchor rod is fixed, although the anchor rod is driven into the soil by a pile driver and is relatively deep, the tightness between the cement column and the soil will be affected after the dam slope is subjected to thermal expansion and contraction in the later stage, so that the cement column will shake in the soil, and therefore the dam slope cannot be well reinforced. Summary of the invention

[0004] The object of the present invention is to provide a dam slope reinforcement device for a pumped storage power station to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] The pulling mechanism includes four round rollers that are rectangularly distributed and rotatably connected to the inner bottom surface of the column. A collar is rotatably connected to the outer wall of the anchor rod. A steel wire that penetrates and slides through the column and is fixed to the collar at the corresponding position is wound and fixed on the outer wall of the round roller. A connecting member is arranged between the tops of the four round rollers. The bottom end of the cylindrical shell is fixedly connected to a spherical shell one that communicates with the inside of the cylindrical shell at the corresponding position. The top end of the anchor rod is fixedly connected to a spherical shell two that communicates with the inside of the anchor rod at the corresponding position. The spherical shell two rolls inside the spherical shell one at the corresponding position. The outer side surface of the spherical shell one is rotatably connected to a rotating shaft that penetrates and is fixed to the spherical shell two at the corresponding position. A gear one is fixedly connected to the outer wall of the rotating shaft. A connecting plate is arranged inside the cylindrical shell. A rack one that meshes with the gear one at the corresponding position is fixedly connected to the bottom end of one side surface of the connecting plate.

[0008] Furthermore: A rectangular hole is penetrated and opened at the top end of the round roller. The connecting member includes a bottom plate that slides on the inner wall of the column. A round rod is rotatably penetrated through the top surface of the bottom plate. Gear fours are fixedly connected to both ends of the outer wall of the round rod. A rotating block is rotatably connected to the bottom surface of the bottom plate at the position corresponding to the round roller. A square rod that is inserted into the rectangular hole at the corresponding position is fixedly connected to the bottom end of the rotating block. A gear five that meshes with the gear four is fixedly connected to the outside of the square rod.

[0009] Furthermore: Two symmetrical sliding grooves are opened on the top surface of the bottom plate. A sliding rod is fixedly connected between the two short side surfaces inside the sliding groove. A limiting block penetrates and slides on the outer wall of the sliding rod. A spring is fixed between the limiting block and the sliding groove at the corresponding position. A moving plate is fixedly connected between the two limiting blocks. A rack two that meshes with the gear four at the corresponding position is fixedly connected to one side surface of the moving plate.

[0010] Furthermore: Two symmetrical jacks are penetrated and opened on the opposite side surfaces of the two limiting blocks. Two symmetrical plug plates of a U-shaped structure penetrate and slide on the outer wall of the bottom plate at the position corresponding to the sliding groove. The plug plates are inserted into the two jacks at the corresponding positions.

[0011] Furthermore: A plurality of sliding rails are fixedly connected to the inner wall of the column at equal angles in a ring shape. A sliding block that slides on the sliding rail at the corresponding position is fixedly connected to the outer wall of the bottom plate at the position corresponding to the sliding rail.

[0012] Preferably: A hexagonal block two is fixedly connected to the top end of the round rod.

[0013] Furthermore: A fixing block is fixedly connected to the top end of the outer wall of the anchor rod. A plurality of threaded holes are penetrated and opened on the top surface of the fixing block at equal angles in a ring shape. The limiting mechanism includes a cylindrical tube. A screw rod that penetrates the protective plate and is screwed into the threaded hole at the corresponding position is rotatably connected to the inner top surface of the cylindrical tube.

[0014] Furthermore, a gear 2 is fixedly connected to the top of the outer wall of the screw rod, a rotating rod is rotatably connected to the inner top surface of the cylindrical tube, and a gear 3 meshing with the plurality of gears 2 is fixedly connected to the outer wall of the rotating rod.

[0015] Preferably, the top end of the rotating rod passes through the top surface of the cylindrical tube at the corresponding position and is fixedly connected with a hexagonal block 1.

[0016] Furthermore, a guide groove is provided on the inner wall of the cylindrical shell, and a limit strip which is slidably plugged into the guide groove at a corresponding position is fixedly connected to one side surface of the connecting plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The steel rope can tilt the anchor rod at the corresponding position by rotating the round roller, and then the tilted anchor rod can be rotated in the soil by rotating the cylindrical shell, so that a chamber similar to a suction cup structure is formed in the soil. Then, concrete is poured into the chamber, and the contact surface with the soil can be increased after the concrete dries. Although the suction cup-shaped cement column will shake after the soil expands and contracts later, the cement column cannot be pulled out of the soil at that time, so the stability of the protective plate can be increased. The improved stability of the protective plate is conducive to preventing soil erosion on the dam slope, thereby increasing the stability of the dam slope;

[0019] 2. Rack 2 is always meshed with gear 4 at the corresponding position under the action of two springs. Therefore, the four steel ropes are always in a straight state during the process of driving the columns and the four cylindrical shells into the soil, so that it is convenient to tilt the anchor rods at the corresponding positions through the steel ropes later;

[0020] 3. By screwing the screw rod into the threaded hole at the corresponding position, the anchor rod can be limited so that the anchor rod and the cylindrical shell at the corresponding position are on the same straight line, making it easier for the pile driver to drive the anchor rod into the soil;

[0021] 4. By recycling the limit mechanism, connecting plates and connecting parts, the purchase quantity can be reduced, thereby reducing the cost expenditure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 10 In an embodiment of the present invention, a dam slope reinforcement device for a pumped storage power station includes a protective plate 1, a column 2 with a conical bottom end is fixedly connected to the bottom surface of the protective plate 1, a cylindrical shell 3 is rotatably connected to the four corners of the bottom surface of the protective plate 1, an anchor rod 31 is arranged at the bottom end of the cylindrical shell 3, a limiting mechanism 4 for vertically fixing the anchor rod 31 is arranged at the bottom surface of the protective plate 1 corresponding to the cylindrical shell 3, a pulling mechanism 5 is arranged inside the column 2, a through hole 11 is penetrated and opened at the top surface of the protective plate 1 corresponding to the column 2, and the top end of the cylindrical shell 3 penetrates the top surface of the protective plate 1 and is fixedly connected with a nut;

[0035] The pulling mechanism 5 includes four round rollers 51 which are distributed in a rectangular shape and are rotatably connected to the inner bottom surface of the column 2. A ring 52 is rotatably connected to the outer wall of the anchor rod 31. A steel rope 511 is wound and fixed on the outer wall of the round roller 51, which slides through the column 2 and is fixed to the ring 52 at the corresponding position. A connecting piece is arranged between the top ends of the four round rollers 51. The bottom end of the cylindrical shell 3 is fixedly connected to a spherical shell 1 32 which is connected to the inside of the cylindrical shell 3 at the corresponding position. The top end of the anchor rod 31 is fixedly connected to a spherical shell 2 34 which is connected to the inside of the anchor rod 31 at the corresponding position. The spherical shell 2 34 rolls in the spherical shell 1 32 at the corresponding position. The outer side surface of the spherical shell 1 32 is rotatably connected to a rotating shaft which penetrates and is fixed to the spherical shell 2 34 at the corresponding position. A gear 1 35 is fixedly connected to the outer wall of the rotating shaft. A connecting plate 36 is arranged inside the cylindrical shell 3. A rack 1 37 which meshes with the gear 1 35 at the corresponding position is fixedly connected to the bottom end of one side of the connecting plate 36.

[0036] Specifically, first, the connecting plate 36 is inserted into the cylindrical shell 3 at the corresponding position, and the rack 37 is meshed with the gear 35 at the corresponding position. The rack 37 moving downward can make the gear 35 drive the anchor rod 31 at the corresponding position to rotate, until the rack 37 moves downward and disengages from the gear 35. At this time, the anchor rod 31 is not restricted by the rack 37 and can rotate freely. Then, the anchor rod 31 and the cylindrical shell 3 at the corresponding position are placed in the same straight line through the limiting mechanism 4, and the four rollers 51 are limited by the connecting piece to prevent rotation. Then, the protective plate 1, the column 2 and the four cylindrical shells 3 are driven into the soil by the pile driver. In the process of the four cylindrical shells 3 and the column 2 being driven into the soil, the steel rope 511 between the roller 51 and the anchor rod 31 at the corresponding position will also be driven into the soil until the protective plate 1 is tightly attached to the inclined surface of the dam slope. Then, the four rollers 51 are rotated through the connecting piece. The rotating rollers 51 can tilt the anchor rod 31 at the corresponding position through the steel rope 511 The cylindrical shell 3 is inclined, and then the rotation of the cylindrical shell 3 can drive the anchor rod 31 at the corresponding position to rotate, and then the concrete is poured into the soil through the grouting equipment. Since the cylindrical shell 3 drives the inclined anchor rod 31 to rotate, a suction cup-like chamber can be formed in the soil, and then by pulling up the connecting plate 36, the rack 37 can drive the gear 35 at the corresponding position to rotate, so that the anchor rod 31 can be rotated in the opposite direction to restore the original state until the rack 37 is separated from the gear 35 at the corresponding position. At this time, the connecting plate 36 can be collected for use when installing other protective plates 1, and then the concrete is poured into the soil through the grouting equipment. Since a chamber with a suction cup structure is formed in the soil, the shape of the concrete after drying is also a suction cup structure, so that the contact area between the concrete and the soil after drying can be increased, so that the stability of the protective plate 1 can be increased. The improved stability of the protective plate 1 is conducive to preventing soil erosion on the dam slope, thereby increasing the stability of the dam slope.

[0037] Example 1

[0038] As Figure 8-10 shown, in this embodiment, a rectangular hole 512 is formed through the top end of the circular roller 51. The connecting member includes a bottom plate 53 that slides on the inner wall of the column 2. A round rod 54 is rotatably penetrated through the top surface of the bottom plate 53. Gear fours 541 are fixedly connected to both ends of the outer wall of the round rod 54. A rotating block 55 is rotatably connected to the bottom surface of the bottom plate 53 corresponding to the circular roller 51. A square rod 551 that is inserted into the rectangular hole 512 at the corresponding position is fixedly connected to the bottom end of the rotating block 55. A gear five 552 that meshes with the gear four 541 at the corresponding position is fixedly connected to the outside of the square rod 551.

[0039] In this embodiment, by inserting the square rod 551 into the rectangular hole 512 at the corresponding position, the rotation of the round rod 54 can cause the two gear fours 541 to rotate. Since the four gear fives 552 mesh with the gear fours 541 at the corresponding positions, the rotating gear fours 541 can cause the four gear fives 552 to rotate. The rotating gear fives 552 can cause the square rod 551 at the corresponding position to drive the circular roller 51 at the corresponding position to rotate. The rotating circular roller 51 can wind up the steel rope 511 at the corresponding position, thereby pulling the anchor rod 31 at the corresponding position towards the column 2, making the anchor rod 31 in an inclined state. Then, by rotating the cylindrical shell 3, the inclined anchor rod 31 can rotate in the soil, forming a chamber similar to a suction cup structure in the soil. When the concrete poured into the chamber dries up, the formed cement column can increase the stability with the soil, thereby increasing the stability of the protection plate 1.

[0040] As Figure 8 and Fig. 9 shown, in this embodiment, two symmetric sliding grooves 531 are formed on the top surface of the bottom plate 53. A sliding rod is fixedly connected between the two short side surfaces inside the sliding groove 531. A limiting block 56 is slidably penetrated through the outer wall of the sliding rod. A spring is fixed between the limiting block 56 and the sliding groove 531 at the corresponding position. A moving plate 561 is fixedly connected between the two limiting blocks 56. A rack two 562 that meshes with the gear four 541 at the corresponding position is fixedly connected to one side surface of the moving plate 561. Two symmetric jacks 563 are formed through the opposite side surfaces of the two limiting blocks 56. Two symmetric C-shaped inserting plates 57 that penetrate and slide on the outer wall of the bottom plate 53 corresponding to the sliding grooves 531 are inserted into the two jacks 563 at the corresponding positions. A plurality of slide rails 21 are fixedly connected to the inner wall of the column 2 in an annular and equiangular manner. A slider 532 that slides on the corresponding slide rail 21 is fixedly connected to the outer wall of the bottom plate 53 corresponding to the slide rail 21. A hexagonal block two is fixedly connected to the top end of the round rod 54.

[0041] In this embodiment, since the rack 2 562 is always meshed with the gear 4 541 at the corresponding position under the action of two springs, the four steel ropes 511 are always in a straight state when the pillars 2 and the four cylindrical shells 3 are driven into the soil. When the protective plate 1 is tightly attached to the inclined surface of the dam slope, the rack 2 562 is separated from the gear 4 541 at the corresponding position, and then the two plug plates 57 are respectively inserted into the limit blocks 56 at the corresponding positions. At this time, the round rod 54 can be driven to rotate by an electric wrench. The rotating round rod 54 can make the two gears 4 541 rotate, and one of the rotating gears 4 541 can make the four gears 552 drive the round roller 51 at the corresponding position to rotate. The rotating round roller 51 can reel in the steel rope 511 at the corresponding position, so that the anchor rod 31 at the corresponding position can be pulled toward the column 2, so that the anchor rod 31 is in an inclined state, and then the connecting piece is removed from the four round rollers 51 for installation and use of the next protective plate 1, and the through hole 11 is blocked to prevent rainwater from flowing into the column 2.

[0042] Embodiment 2

[0043] like Figure 5-7 As shown, in this embodiment, the top end of the outer wall of the anchor rod 31 is fixedly connected to a fixing block 33, and a plurality of threaded holes are formed in an annular manner at equal angles on the top surface of the fixing block 33. The limiting mechanism 4 includes a cylindrical tube 41, and a screw 42 is rotatably connected to the inner top surface of the cylindrical tube 41, which penetrates the protective plate 1 and is screwed with the threaded holes at corresponding positions. A gear 2 43 is fixedly connected to the top end of the outer wall of the screw 42, and a rotating rod is rotatably connected to the inner top surface of the cylindrical tube 41. A gear 3 44 meshing with a plurality of gears 2 43 is fixedly connected to the outer wall of the rotating rod. The top end of the rotating rod penetrates the top surface of the cylindrical tube 41 at corresponding positions and is fixedly connected to a hexagonal block 1 45. A guide groove is formed on the inner wall of the cylindrical shell 3, and a limiting strip slidably plugged into the guide groove at the corresponding position is fixedly connected to one side of the connecting plate 36.

[0044] In this embodiment, by using an electric wrench to drive the gear three 44 to rotate, the rotating gear three 44 can drive the four gear twos 43 at the corresponding positions to rotate, and the rotating gear two 43 can make the screw rod 42 at the corresponding position screw into the threaded hole at the corresponding position, so that the anchor rod 31 can be limited, so that the anchor rod 31 and the cylindrical shell 3 at the corresponding position are on the same straight line, so that it is convenient for the pile driver to drive the anchor rod 31 into the soil. After driving into the soil, the electric wrench is used to reversely drive the gear three 44 to rotate in the opposite direction, so that the screw rod 42 and the corresponding cylindrical shell 3 are aligned. The threaded hole at the position is disengaged, and then the entire limiting mechanism 4 can be taken out from the protective plate 1. At the same time, when the rack 37 at the corresponding position is pulled up by the connecting plate 36, the rack 37 can make the gear 35 at the corresponding position rotate, so that the anchor rod 31 at the corresponding position can be rotated in the opposite direction to restore its original state. Then the pulled out connecting plates 36 are collected together for use when installing the next protective plate 1 together with the limiting mechanism 4 and the connecting parts. Therefore, the order quantity of the connecting plates 36, the limiting mechanism 4 and the connecting parts can be reduced, thereby reducing the cost expenditure.
