Description

Technical Field

[0001] This application relates to the field of rope winding technology, and more specifically, to a winding device for a hydroelectric power station. Background Technology

[0002] In the daily operation and maintenance of hydropower stations, ropes are frequently used, but the winding and coiling operations face significant technical challenges. Due to the high humidity of the hydropower station environment, the surface of the ropes often adheres to a large amount of water stains and mud and dirt. Traditional winding devices lack targeted cleaning structures, causing residual contaminants to repeatedly rub against the surface during winding, accelerating surface wear and significantly shortening service life. Although some existing winding devices have added cleaning functions, they do not solve the problem of real-time cleaning during the winding process. Maintenance personnel still need to spend a lot of time on secondary cleaning, resulting in low work efficiency and safety hazards. In addition, manual cleaning can easily cause surface damage, especially for large-diameter ropes, and improper cleaning operations may damage their structural integrity. Therefore, there is an urgent need to develop a winding device with integrated cleaning functions to simultaneously remove water and surface contaminants during the winding process. Utility Model Content

[0007] In some embodiments, the first roller and the second roller are pressed together at a position lower than the position where the unwinding reel is taking up the wire.

[0008] In some embodiments, when the unwinding reel is taking in the yarn, the yarn enters from below the second roller and wraps around between the first roller and the second roller, and enters the unwinding reel from above the first roller.

[0009] In some embodiments, the dewatering mechanism further includes a base and a mounting base, the mounting base being elastically mounted on the base and the base being mounted on the frame, the first roller being mounted on the base and the second roller being mounted on the mounting base, the second roller being squeezed by the elasticity of the mounting base against the first roller.

[0022] Please see Figure 1 This application discloses a winding device 100 for a hydroelectric power station, used for winding damp rope. The winding device 100 includes a frame 10, an unwinding reel 20, a water-squeezing mechanism 30, and a cleaning mechanism 40. The unwinding reel 20 is used for releasing and winding the rope. The water-squeezing mechanism 30 includes a first roller 31 and a second roller 32 that press against each other, with the first roller 31 above the second roller 32, and the rope passing between the first roller 31 and the second roller 32. The cleaning mechanism 40 is used to clamp the rope to remove dirt from its surface.

[0023] The winding device 100 of this application effectively solves the problem of damage caused by moisture contamination during the winding of hydropower station cables by integrating a dual-function structure of water squeezing and cleaning. Specifically, the squeezing design of the first roller 31 and the second roller 32 can simultaneously squeeze out surface moisture during the cable's movement, reducing the risk of oxidation and corrosion caused by residual water stains; the cleaning mechanism 40 adopts a clamping method to remove attached mud and sand through mechanical contact friction.

[0024] Specifically, please refer to Figure 1The frame 10 has a frame structure, and a receiving tray 11 is provided on the frame 10. The receiving tray 11 is located at the bottom of the frame 10 and is used to collect the squeezed water and scraped dirt to prevent secondary pollution. The unwinding reel 20, the water squeezing mechanism 30 and the cleaning mechanism 40 are arranged in a V-shape along the longitudinal direction of the frame 10 to ensure that the water-squeezed rope is prevented from flowing back during the winding process.

[0025] Please see Figure 1 The unwinding reel 20 includes a spool 21 and a baffle 22. The spool 21 is used to wind the rope. Multiple reinforcing ribs 211 are evenly spaced along the axial direction on the outer periphery of the spool 21 to enhance torsional stiffness. At the same time, drainage gaps are formed between adjacent reinforcing ribs 211 to facilitate the drainage of moisture from the rope surface. The baffle 22 has a ring-shaped array of permeable holes to accelerate the evaporation of residual moisture in the rope.

[0026] Please see Figure 1 and Figure 2 The squeezing mechanism 30 includes a first roller 31, a second roller 32, a base 33, a mounting base 34, a screw 35, and an elastic element 36. The mounting base 34 is elastically mounted on the base 33, which is mounted on the frame 10. The first roller 31 is mounted on the base 33, and the second roller 32 is mounted on the mounting base 34. The second roller 32 compresses the first roller 31 by the elasticity of the mounting base 34. The elastic element 36 is sleeved on the first roller 32, and the screw 35 passes through the mounting base 34 and is fixed to the base 33. The elastic element 36 is located between the nut and the mounting base 34. The squeezing force between the two rollers can be controlled by adjusting the compression of the elastic element 36 by turning the screw 35.

[0027] Furthermore, the position where the first roller 31 and the second roller 32 press against each other is lower than the position where the unwinding reel 20 takes up the wire, which refers to the position where the reel 21 of the unwinding reel 20 has just been wound up. In one embodiment, the position where the first roller 31 and the second roller 32 press against each other is lower than the bottommost position of the circular baffle 22.

[0028] Furthermore, to facilitate the winding of the rope on the unwinding reel 20, grooves 37 are provided on the surfaces of the first roller 31 and the second roller 32 for the rope to pass through. These grooves 37 are located in the middle of the rollers. Alternatively, the same effect can be achieved by providing a groove 37 on either the first roller 31 or the second roller 32. The rope passes through the grooves 37 to prevent deviation. The depth of the grooves 37 is 1 / 3 to 1 / 2 of the rope diameter, ensuring that water is fully squeezed out during compression without damaging the rope.

[0029] Furthermore, in order to facilitate the squeezing out of water from the rope, when the unwinding reel 20 is winding the rope, the rope enters from below the second roller 32, is squeezed between the two rollers, and is then discharged from above the first roller 31, forming an S-shaped winding path to enhance the water squeezing effect.

[0030] Please see Figure 1 The cleaning mechanism 40 includes a guide shaft 41, a scraping mother block 42, and a scraping daughter block 43. The guide shaft 41 passes through the scraping mother block 42 and the scraping daughter block 43. The scraping mother block 42 and / or the scraping daughter block 43 have notches 44. The rope passes through the notches 44. The scraping daughter block 43 slides along the guide shaft 41 to change the size of the notches 44 to scrape off dirt from the surface of the rope.

[0031] Specifically, two guide shafts 41 are arranged parallel to each other on the frame 10. The scraping mother block 42 has an L-shaped structure, and the scraping daughter block 43 cooperates with the scraping mother block 42 to form a cuboid-shaped block. The notch 44 of the scraping mother block 42 is opened at the bend position on the inner side of the L-shape, and the notch 44 of the scraping daughter block 43 is opened at the position corresponding to the bend on the inner side of the L-shape of the scraping mother block 42. It should be noted that the same effect can be achieved if either the scraping mother block 42 or the scraping daughter block 43 has a notch 44 at the corresponding position.

[0032] The upper guide shaft 41 passes through the scraping mother block 42 and the scraping daughter block 43, while the lower guide shaft 41 passes through the middle of the L-shaped rightward extension of the scraping mother block 42. The scraping mother block 42 and the scraping daughter block 43 are slidably mounted on the guide shaft 41 and are adjusted and tightened by screws 35 to accommodate different wire diameters.
