Description

Technical Field

[0001] This invention relates to the field of de-icing technology, and in particular to a de-icing device for the dam slope of a pumped storage power station and its usage method. Background Technology

[0002] Pumped storage is an energy storage technology that uses water as the energy storage medium, converting electrical energy into potential energy to store and manage electrical energy. It utilizes electricity generated during off-peak hours to pump water to an upper reservoir, and releases it to a lower reservoir during peak hours to generate electricity. This converts excess electricity generated during periods of low grid load into high-value electricity generated during peak periods. It is suitable for frequency and phase regulation, stabilizing the frequency and voltage of the power system, and can also improve the efficiency of thermal and nuclear power plants within the system. In northern my country, the climate is cold, and reservoirs often freeze when temperatures drop to a certain level. Large ice-breaking equipment is typically required to break up the ice surface over a large area for upper reservoirs. For pumped storage of the lower reservoir, holes need to be drilled in the ice surface to insert pipes for pumping. Current ice-breaking devices cannot adjust the size of the holes according to the pipe radius, and the slippery ice surface makes the equipment unstable during operation. Therefore, a de-icing device for the dam slope of a pumped storage power station is designed to solve the aforementioned problems. Summary of the Invention

[0003] This invention addresses the problems mentioned in the background section regarding the inability of previous ice-breaking devices to adjust the size of the holes drilled on the ice surface according to the radius of the pipeline, and the instability of the equipment due to the slippery ice surface and lack of adhesion during operation. It provides a de-icing device for the dam slope of a pumped storage power station that can increase adhesion and improve device stability, and can also adjust the size of the holes drilled on the ice surface according to the pipeline.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows: A de-icing device for a pumped-storage power station dam slope includes a base plate with a vertical plate at the upper end. A liftable ice-breaking device is mounted on the vertical plate. The ice-breaking device includes a rotatable first disc with multiple ice-breaking blades at its lower end. When the first disc rotates, the ice-breaking blades can rotate in a circular motion while oscillating up and down. A rotatable worm gear is also provided at the upper end of the first disc. When the worm gear rotates, the ice-breaking blades can move synchronously inward or outward. Multiple suction cups are provided on both sides of the lower end of the base plate, and a rotatable bidirectional threaded rod is provided in the middle of the upper end of the base plate. When the bidirectional threaded rod rotates, the multiple suction cups can move synchronously outward and then downward, adsorbing and fixing the ice surface.

[0005] The left and right ends of the outer surface of the bidirectional threaded rod are respectively threaded to long sliders that are slidably connected to the base plate. The front and rear ends of the long sliders are respectively provided with reinforcing plates, and the suction cups are respectively installed on the corresponding reinforcing plates.

[0006] The reinforcing plate is slidably connected to the left and right ends of the corresponding long slider. The upper surface of the reinforcing plate is fixedly connected to the support, and the inner wall of the support is fixedly connected to the first sliding pin. Multiple track plates are fixedly connected to the left and right sides of the upper surface of the base plate. The inner wall of the track plate is provided with track grooves that cooperate with the corresponding first sliding pins.

[0007] The inner walls of the left and right ends of the reinforcing plate are respectively fixed with straws, and the suction cups are respectively set at the lower ends of the corresponding straws. The inner walls of the straws are respectively slidably connected with straws, and the upper surfaces of the straws are respectively fixed with piston rods, which are respectively fixed to the long sliders.

[0008] The front surface of the upright plate is slidably connected to a long slide plate, and the front surface of the long slide plate is fixedly connected to a support frame. The ice-breaking device also includes a first motor fixedly connected to the long slide plate. The output end of the first motor is fixedly connected to a long rotating shaft that is rotatably connected to the support frame. The upper end of the outer surface of the long rotating shaft is fixedly connected to a drive pulley. The rear pulley of the drive pulley is connected to a driven pulley that is rotatably connected to the long slide plate. The inner wall of the center of the driven pulley is threadedly connected to a long threaded rod that is fixedly connected to the upright plate.

[0009] The inner wall of the support frame is slidably connected to a first slide plate. The inner wall of the middle part of the first slide plate is rotatably connected to a transmission shaft that is slidably connected to a long rotating shaft. The first disc is fixed to the lower end surface of the transmission shaft. The inner wall of the bottom end of the support frame is rotatably connected to a driving bevel gear that is slidably connected to the transmission shaft. A driven bevel gear meshes with the outer surface of the driving bevel gear. An eccentric wheel is coaxially fixed to one side of the driven bevel gear. A sleeve rod that is hinged to the first slide plate is rotatably connected to the outer surface of the eccentric wheel.

[0010] The worm gear is rotatably connected to the upper surface of the first disk. A worm wheel, which is rotatably connected to the first disk, is meshed on the outer surface of the worm gear. Multiple evenly distributed first connecting rods are hinged at the non-center of the lower surface of the worm wheel. The other end of each first connecting rod is hinged to a square slider that is slidably connected to the first disk. The ice-breaking blade is fixedly connected to the lower surface of the corresponding square slider.

[0011] A drill rod is fixed at the center of the lower surface of the first disk.

[0012] A method for using a de-icing device on the slope of a pumped storage power station dam includes the following steps; S1. After the device reaches the designated position, the rotatable bidirectional threaded rod enables multiple suction cups to move outward and then downward simultaneously to adhere to and fix the ice surface, thus stabilizing the device in the designated position. S2. The position of the ice-breaking blade can be adjusted according to the radius of the pipe by means of a rotatable worm gear; S3. Through the liftable ice-breaking device and the rotatable first disc, when the first disc rotates, it can drive the corresponding ice-breaking blade to rotate in a circle and oscillate up and down. Then, by lowering the ice-breaking device and cooperating with the ice-breaking blade, it can break the ice and open a hole on the designated ice surface.

[0013] The present invention has a novel and ingenious structure, and has the following advantages compared with the prior art: In use, once the device is moved to the designated position, a rotatable bidirectional threaded rod drives the corresponding suction cup to move outward. After moving outward, the suction cup moves downward, generating suction upon contact with the ice surface, thus securing the entire device and ensuring stability during ice breaking. The ice-breaking device can cut and break the ice. Its adjustable height allows it to rise to a designated position, away from the ground for easy movement. Upon descending to the designated position and contacting the ground, the ice-breaking device activates and continues its descent. The system breaks up the ice surface. Starting the first motor causes the first disc to rotate, which in turn drives the corresponding ice-breaking blade to rotate in a circle while oscillating up and down. The rotating blade cuts through the ice, while the oscillating motion reduces resistance during cutting, preventing jamming or damage from excessive load. Driving the first handle rotates the worm gear, which in turn drives the corresponding ice-breaking blade to move synchronously inward or outward. Moving the blade inward reduces the ice-cutting radius, and moving it outward increases it, allowing for adaptive adjustments based on the pipe radius. Attached Figure Description

Detailed Implementation

[0026] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1-11 As shown, the present invention provides a de-icing device for the dam slope of a pumped storage power station, including a base plate 1. The upper end of the base plate 1 is provided with a vertical plate 15, and the vertical plate 15 is provided with a liftable ice-breaking device. The ice-breaking device includes a rotatable first disc 29, and a plurality of ice-breaking blades 31 are provided at the lower end of the first disc 29. When the first disc 29 rotates, it can form a structure in which the ice-breaking blades 31 rotate in a circle and oscillate up and down. The upper end of the first disc 29 is also provided with a rotatable worm gear 35. When the worm gear 35 rotates, it can form a structure in which the ice-breaking blades 31 move synchronously inward or outward. A plurality of suction cups 11 are provided on both sides of the lower end of the base plate 1, and a rotatable bidirectional threaded rod 4 is provided in the middle of the upper end of the base plate 1. When the bidirectional threaded rod 4 rotates, it can form a structure in which the plurality of suction cups 11 move synchronously outward and then downward and adsorb and fix the ice surface.

[0028] like Figure 1-8 As shown, foot brake wheels 3 are fixed to each corner of the lower surface of the base plate 1, facilitating the movement of the device to a designated position. A handle 2 is fixed to the rear side of the upper surface of the base plate 1, allowing for easy control of the device's movement. The foot brake wheels 3 are existing technology and will not be described further. When the device moves to the designated position, a rotatable bidirectional threaded rod 4 drives the corresponding suction cup 11 to move outward. After moving outward, the suction cup 11 moves downward, generating suction upon contact with the ice surface, thus fixing the entire device and ensuring stability during ice breaking. The ice-breaking device can cut and break the ice surface. The liftable ice-breaking device allows it to rise to a designated position and move away from the ground. The device is designed for easy movement. After descending to the designated position, the ice-breaking device contacts the ground, activates, and continues to descend to break the ice. A rotatable first disc 29 drives the corresponding ice-breaking blade 31 to rotate in a circle while oscillating up and down. The rotating disc cuts through the ice, while the oscillating motion reduces resistance during cutting, preventing jamming or damage from excessive load. A rotatable worm gear 35 drives the ice-breaking blade 31 to move inward or outward simultaneously. Moving inward reduces the ice-cutting radius, while moving outward increases it, allowing for adaptive adjustments based on the pipe radius.

[0029] The left and right ends of the outer surface of the bidirectional threaded rod 4 are respectively threaded to long sliders 5 that are slidably connected to the base plate 1. The front and rear ends of the long slider 5 are respectively provided with reinforcing plates 6, and the suction cups 11 are respectively installed on the corresponding reinforcing plates 6.

[0030] like Figure 4 As shown, the left and right ends of the outer surface of the bidirectional threaded rod 4 are rotatably connected to bearing seats, and the bottom ends of the bearing seats are fixed to the lower end surface of the base plate 1, limiting the bidirectional threaded rod 4 to rotate only. The long slider 5 is slidably connected to the lower end surface of the base plate 1 on the left and right sides respectively. The bidirectional threaded rod 4 is driven by a motor, transmission gear or pulley. The motor, transmission gear and pulley are all existing technologies and will not be described in detail. The left and right ends of the outer surface of the bidirectional threaded rod 4 are respectively provided with two sections of threads with the same pitch but different directions. When the bidirectional threaded rod 4 rotates, the long slider 5 will move outward due to the threaded connection with it. When the long slider 5 moves outward, it will drive the corresponding reinforcing plate 6, suction cup 11 and other components to move outward synchronously. The threaded connection between the bidirectional threaded rod 4 and the long slider 5 has a self-locking function. When the long threaded rod 17 does not rotate, it can limit the position of the long slider 5, so that the long slider 5, suction cup 11 and other components are fixed in the designated position.

[0031] The reinforcing plate 6 is slidably connected to the left and right ends of the corresponding long slider 5. The upper surface of the reinforcing plate 6 is fixedly connected to the support 7, and the inner wall of the support 7 is fixedly connected to the first sliding pin 8. The upper surface of the base plate 1 is fixedly connected to the left and right sides of the base plate 9, and the inner wall of the track plate 9 is provided with track grooves 10 that cooperate with the corresponding first sliding pin 8.

[0032] like Figure 3-5 As shown, the reinforcing plate 6 is slidably connected to the inner wall of the long slider 5. A rectangular groove is formed on the upper surface of the base plate 1, and the upright 7 is slidably connected to the inner wall of the rectangular groove. The track groove 10 includes two sections: a horizontal groove and an inclined groove. When the first sliding pin 8 engages in the inner wall of the horizontal groove, the corresponding reinforcing plate 6 will move horizontally inward or outward. When the first sliding pin 8 engages in the inner wall of the horizontal groove, it will cause the reinforcing plate 6 to move downward outward or upward inward. That is, when the long slider 5 moves outward, it can drive the corresponding reinforcing plate 6 and the upright 7 to move outward synchronously. When the upright 7 moves outward, it will drive the... The corresponding first sliding pin 8 moves outward. When the first sliding pin 8 moves outward, it engages with the transverse groove, causing the corresponding reinforcing plate 6, stand 7, suction cup 11, etc., to move horizontally outward simultaneously. When the long slider 5, reinforcing plate 6, first sliding pin 8, suction cup 11, etc., move outward to the designated position, the first sliding pin 8 enters the inner wall of the inclined groove. After the first sliding pin 8 enters the inner wall of the inclined groove, it will move outward and downward at the same time. That is, the corresponding reinforcing plate 6, stand 7, suction cup 11 will move outward and downward at the same time. When the suction cup 11 moves downward, it can be released to the ice surface.

[0033] The inner walls of the left and right ends of the reinforcing plate 6 are respectively fixed with straws 12, and the suction cups 11 are respectively set at the lower ends of the corresponding straws 12. The inner walls of the straws 12 are respectively slidably connected with straws 13, and the upper surfaces of the straws 13 are respectively fixed with piston rods 14, which are respectively fixed on the long slider 5.

[0034] like Figure 5-6As shown, support seats 37 are fixedly connected to the upper end of the outer surface of the piston rod 14, and the bottom ends of the support seats 37 are fixedly connected to the corresponding long sliders 5. The piston rod 14 and the suction tube 13 can move back and forth with the suction tube 12, but cannot move up and down. The suction cup 11 is made of rubber and has a certain elastic deformation. When the reinforcing plate 6, the suction cup 11, etc., move downward and outward under the engagement of the first sliding pin 8 and the track groove 10, when the suction cup 11 moves downward to the designated position, that is, after contacting the ice surface, since the ice surface is usually relatively smooth, the suction cup 11 can move downward. After the disk 11 moves downward and contacts the ice surface, it continues to move downward, which will compress and deform the suction cup 11. Since the piston rod 14 and the suction tube 13 are essentially fixed to the long slider 5, the piston rod 14 and the suction tube 13 cannot move up or down under the limitation of the long slider 5. When the suction tube 12 and the suction cup 11 move downward, they move relative to the suction tube 13, which is equivalent to the suction tube 13 moving upward. When the piston rod 14 moves upward, it will create a negative pressure state inside the suction tube 12, thereby allowing the suction cup 11 to adhere and fix to the ice surface, which can strengthen the stability of the device.

[0035] The front surface of the upright plate 15 is slidably connected to a long slide plate 16, and the front surface of the long slide plate 16 is fixedly connected to a support frame 22. The ice-breaking device also includes a first motor 18 fixedly connected to the long slide plate 16. The output end of the first motor 18 is fixedly connected to a long rotating shaft 19 rotatably connected to the support frame 22. The upper end of the outer surface of the long rotating shaft 19 is fixedly connected to a drive pulley 20. The rear pulley of the drive pulley 20 is connected to a driven pulley 21 rotatably connected to the long slide plate 16. The inner wall of the center of the driven pulley 21 is threadedly connected to a long threaded rod 17 fixedly connected to the upright plate 15.

[0036] like Figure 7-8 As shown, support plates are fixed to the upper and lower ends of the outer surface of the long threaded rod 17, and the bottom ends of the support plates are fixed to the front end surface of the vertical plate 15. The long slide plate 16 is slidably connected to the front end surface of the vertical plate 15. The support frame 22 is used to install the first disc 29, the long rotating shaft 19 and other components. The function of the first motor 18 is to provide rotational power to the long rotating shaft 19, the first disc 29 and other components. The motor is existing technology and will not be described in detail. The driven pulley 21 passes through and is rotatably connected to the inner wall of the long slide plate 16. When the first motor 18 is started, it can drive the corresponding long rotating shaft 19 to rotate. The rotation of the long rotating shaft 19 will drive the driving pulley 20 and the driven pulley 21 to rotate synchronously. When the driven pulley 21 rotates, it will cause the driven pulley 21, the long slide plate 16, the support frame 22 and other ice-breaking devices to move slowly up or down through the threaded connection with the long threaded rod 17, thereby driving the corresponding ice-breaking devices to rise and fall.

[0037] The inner wall of the support frame 22 is slidably connected to a first slide plate 23. The inner wall of the middle part of the first slide plate 23 is rotatably connected to a transmission shaft 24 that is slidably connected to a long rotating shaft 19. The first disc 29 is fixedly connected to the lower end surface of the transmission shaft 24. The inner wall of the bottom end of the support frame 22 is rotatably connected to a driving bevel gear 25 that is slidably connected to the transmission shaft 24. A driven bevel gear 26 meshes on the outer surface of the driving bevel gear 25. An eccentric wheel 27 is coaxially fixed to one side of the driven bevel gear 26. A sleeve rod 28 that is hinged to the first slide plate 23 is rotatably connected to the outer surface of the eccentric wheel 27.

[0038] like Figure 7-9 As shown, the first sliding plate 23 is slidably connected to the inner wall of the support frame 22. The long rotating shaft 19 and the drive shaft 24 are splinedly connected. The drive shaft 24 can slide up and down at the lower end of the outer surface of the long rotating shaft 19, and can also drive the drive shaft 24 to rotate when the long rotating shaft 19 rotates. The drive shaft 24 and the driving bevel gear 25 are splinedly connected. Similarly, the drive shaft 24 can slide up and down on the inner wall of the driving bevel gear 25, and can also drive the driving bevel gear 25 to rotate when the drive shaft 24 rotates. A rotating shaft is fixed to the inner wall of the driven bevel gear 26 and the eccentric wheel 27, and the rotating shaft is rotatably connected to the inner wall of the support frame 22. The first sliding plate 23, the sleeve rod 28, and the eccentric wheel 27 are installed and shaped as follows. Figure 9 As shown, when the eccentric wheel 27 rotates, it will cause one end of the sleeve rod 28 to rotate in a circle, while the other end will pull the corresponding first slide plate 23 to move back and forth slightly. The back and forth movement of the first slide plate 23 will drive the corresponding transmission shaft 24 and the first disc 29 to oscillate back and forth. When the long rotating shaft 19 rotates, it will drive the corresponding transmission shaft 24 to rotate. The rotation of the transmission shaft 24 will drive the corresponding driving bevel gear 25 and the first disc 29 to rotate. When the driving bevel gear 25 rotates, it will mesh with the driven bevel gear 26, causing the driven bevel gear 26 and the eccentric wheel 27 to rotate. When the eccentric wheel 27 rotates, it will drive the first slide plate 23, the transmission shaft 24, and the first disc 29 to oscillate back and forth, thus causing the disc to rotate and oscillate back and forth.

[0039] The worm 35 is rotatably connected to the upper surface of the first disk 29. A worm wheel 34, which is rotatably connected to the first disk 29, is meshed on the outer surface of the worm 35. Multiple evenly distributed first connecting rods 33 are hinged at the non-center of the lower surface of the worm wheel 34. The other end of each first connecting rod 33 is respectively hinged to a square slider 32 that is slidably connected to the first disk 29. The ice-breaking blade 31 is respectively fixed to the lower surface of the corresponding square slider 32.

[0040] like Figure 10-11As shown, bearing seats are rotatably connected to the left and right ends of the outer surface of the worm gear 35, and the bottom ends of the bearing seats are fixed to the upper surface of the first disk 29, limiting the worm gear 35 to rotate only on the first disk 29. Multiple rectangular grooves are provided on the first disk 29, and the square slider 32 can slide inward or outward along the inner wall of the rectangular groove. The first connecting rod 33, the square slider 32, and the icebreaker 31 are installed and shaped as follows: Figure 11 As shown, the worm gear 35 has a first handle 36 fixed to its left and right ends. The function of the first handle 36 is to facilitate the rotation of the worm gear 35. When it is necessary to adjust the position of the icebreaker 31, that is, to adjust the position of the icebreaker 31 according to the pipe radius, the worm gear 35 can be driven to rotate by rotating the first handle 36. The rotation of the worm gear 35, through meshing with the worm wheel 34, will cause the worm wheel 34 to rotate. The rotation of the worm wheel 34 will drive the inner end of the first connecting rod 33 to rotate in a circle. The outer end of the first connecting rod 33 will drive the corresponding square slider 32 and icebreaker 31 to move inward or outward, thereby adjusting the position of the icebreaker 31 according to the pipe size. Furthermore, the worm wheel 34 and worm gear 35 have a self-locking function under meshing. When the worm gear 35 does not rotate, the positions of the corresponding worm wheel 34, first connecting rod 33, square slider 32, and icebreaker 31 are fixed, so that the icebreaker 31 can work stably.

[0041] A drill rod 30 is fixedly attached to the center of the lower surface of the first disk 29.

[0042] like Figure 10 As shown, the drill rod 30 can break or drill holes in the middle of the ice surface during hole opening, making it easier to clean up ice debris in the middle.

[0043] A method for using a de-icing device on the slope of a pumped storage power station dam includes the following steps; S1. After the device reaches the designated position, the rotatable bidirectional threaded rod 4 enables multiple suction cups 11 to move outward and then downward simultaneously to adhere to and fix the ice surface, thus stabilizing the device in the designated position. S2. The position of the ice-breaking blade 31 can be adjusted according to the radius of the pipe by means of the rotatable worm gear 35; S3. Through the liftable ice-breaking device and the rotatable first disc 29, when the first disc 29 rotates, it can drive the corresponding ice-breaking blade 31 to rotate in a circle and oscillate up and down. Then, by lowering the ice-breaking device and cooperating with the ice-breaking blade 31, it can break the ice and open a hole on the designated ice surface.

[0044] In use, when the device is moved to a designated position, the rotatable bidirectional threaded rod 4 drives the corresponding suction cup 11 to move outward. After moving outward, the suction cup 11 moves downward, and upon contact with the ice surface, it generates suction, thus fixing the entire device and ensuring stability during ice breaking. The ice-breaking device can cut and break the ice surface. The liftable ice-breaking device allows it to rise to a designated position, away from the ground for easy movement, and then descend to the designated position, contacting the ground. The ice-breaking device then activates and continues to descend, thus breaking the ice surface. Breaking: By starting the first motor 18, the first disc 29 can rotate, which in turn drives the corresponding ice-breaking blade 31 to rotate in a circle and oscillate up and down. When rotating in a circle, the ice-breaking blade 31 can cut the ice surface. When oscillating up and down, it can reduce the resistance of the ice-breaking blade 31 during cutting, preventing jamming or damage due to excessive load on the device. By driving the first handle 36, the worm gear 35 can rotate. When the worm gear 35 rotates, it can drive the corresponding ice-breaking blade 31 to move inward or outward synchronously. When the ice-breaking blade 31 moves inward, it can reduce the ice surface cutting radius. Similarly, when it moves outward, it can increase the ice surface cutting radius, making adaptive adjustments according to the radius of the pipeline.
