Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformers, and in particular to a transformer sunshade and rain protection device. Background Technology
[0002] A transformer shading and rain protection device is a device used to protect transformers from direct sunlight and rain erosion. It is usually installed on or around the transformer to prevent the internal temperature from rising due to direct sunlight or internal corrosion caused by rain.
[0003] Existing transformer sunshade and rain protection devices typically have a fixed length for their sunshade and rain shields, which cannot be retracted or extended. This results in poor protection during summer or heavy rain, and the inability to remove debris from the surface of the sunshade and rain shields can lead to structural loosening due to excessive debris accumulation.
[0004] Therefore, in view of the problems of existing transformer sunshade and rain protection devices, such as the inability to retract or extend the sunshade and rain protection panels during use, the poor protective effect in summer or rainstorm weather, and the inability to remove debris from the top of the sunshade and rain protection panels, there is an urgent need to design a new type of transformer sunshade and rain protection device. Utility Model Content
[0005] To overcome the problems of existing transformer sunshade and rain protection devices, such as the inability to retract or extend the sunshade and rain shield during use, resulting in poor protection in summer or rainstorm weather, and the inability to remove debris from the top of the sunshade and rain shield.
[0006] The technical solution of this utility model is as follows: a transformer sunshade and rainproof device, including a protective top; it also includes a movable plate, a double-acting screw, a driven gear, a mounting base, a drive motor, a drive gear, a mounting frame, a waterproof motor, a screw, a movable base, and a scraper. Movable plates are slidably connected to both the front and rear surfaces of the protective top. A double-acting screw is threaded between the two movable plates. A driven gear is installed at the middle position of the outer surface of the double-acting screw. A drive gear meshes with the side of the driven gear. A drive motor is connected to the rear surface of the drive gear. A mounting base is installed on the rear surface of the drive motor. A mounting frame is set at the front position of the upper surface of the protective top. A waterproof motor is installed on the right side surface of the mounting frame. The output end of the waterproof motor passes through the right side wall of the mounting frame and is connected to one end of the screw. The other end of the screw is rotatably connected to the left side of the inner surface of the mounting frame. A movable base is threaded through the outer surface of the screw. A scraper is connected to the rear surface of the movable base. The bottom surface of the scraper is in contact with the top surface of the protective top.
[0007] Preferably, by setting a drive motor, its output end can drive the drive gear to rotate during operation. When the drive gear rotates, it can drive the double-acting screw to rotate through the cooperation of the driven gear. The two movable plates can move back and forth under the cooperation of the threads on the outer surface of the double-acting screw, thereby expanding the rain and sun protection range. Furthermore, by setting a waterproof motor, its output end can drive the screw to rotate during operation. When the screw rotates, it can drive the movable seat that is threaded to it to move back and forth, thereby driving the scraper to slide along the upper surface of the protective top, thereby scraping away fallen leaves and other debris on the top. This solves the problems of existing transformer sunshade and rain protection devices, where the length of the sunshade and rainproof plate is usually fixed and cannot be retracted or extended, resulting in poor protection in summer or rainstorm weather, and the inability to scrape away debris on the upper surface of the sunshade and rainproof plate, which can easily lead to structural loosening due to excessive debris accumulation.
[0008] Preferably, sliders are installed on both the left and right surfaces of the two movable plates, and the movable plates are slidably connected to the protective top through the sliders.
[0009] Preferably, inclined plates are installed at the ends of the two movable plates away from the bidirectional lead screw, and the inclined plates are fixed to the movable plates by welding.
[0010] Preferably, two symmetrical support rods are installed at the middle of the bottom surface of the protective top, and guide rods are provided on the front and rear sides of the outer surface of the two support rods, with the movable plate slidably connected to the corresponding guide rods.
[0011] Preferably, a limiting frame is installed on the rear side of the upper surface of the protective top, and limiting rods are installed on the left and right sides of the inner surface of the limiting frame. A limiting block is slidably connected through the outer surface of the limiting rod, and the front surface of the limiting block is connected to the rear end of the scraper.
[0012] Preferably, damping springs are provided at the corners of the bottom surface of the protective top, and washers are installed on the bottom surface of the damping springs.
[0013] Preferably, a rain sensor is installed on the top surface of the mounting frame, and a controller is installed on the right side of the bottom surface of the protective top.
[0014] Preferably, the bottom of the mounting base is fixed to the top of the transformer cabinet with screws.
[0015] The beneficial effects of this utility model are:
[0016] 1. By setting a drive motor, its output end can drive the active gear to rotate, the active gear drives the driven gear to rotate, and the driven gear can drive the double-sided lead screw to rotate. The two movable plates can move back and forth in cooperation with the threads on the outer surface of the double-sided lead screw, thereby expanding the range of rain and sun protection. This solves the problem that the length of the sun and rain protection plate of the existing transformer sunshade and rain protection device is usually fixed and cannot be retracted or extended, resulting in poor protection effect in summer or rainstorm weather.
[0017] 2. By setting up a waterproof motor, the output end can drive the screw to rotate. The rotation of the screw can drive the moving seat to move back and forth, thereby driving the scraper to slide along the upper surface of the protective top, thus scraping away fallen leaves and other debris on the top. This solves the problem that the existing transformer sunshade and rainproof device cannot scrape away debris from the upper surface of the sunshade and rainproof board during use, and that excessive accumulation of debris can easily lead to structural loosening.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please see Figures 1-5This utility model provides an embodiment of a transformer sunshade and rainproof device, including a protective top 1; it also includes a movable plate 2, a bidirectional lead screw 3, a driven gear 4, a mounting base 5, a drive motor 6, a driving gear 7, a mounting frame 12, a waterproof motor 13, a screw 14, a movable base 15, and a scraper 16. Movable plates 2 are slidably inserted into the front and rear surfaces of the protective top 1. A bidirectional lead screw 3 is threaded between the two movable plates 2. A driven gear 4 is installed at the middle position of the outer surface of the bidirectional lead screw 3. The driven gear 4 meshes with the driving gear 7 on its side. The drive motor 6 is connected to the rear surface of the driving gear 7. A mounting base 5 is installed on the rear surface of the drive motor 6. A mounting frame 12 is located at the front position of the upper surface of the protective top 1. A waterproof motor 13 is installed on the right side surface of the mounting frame 12. The output end of the waterproof motor 13 passes through the right side wall of the mounting frame 12 and is connected to one end of the screw 14. The other end of 4 is rotatably connected to the left side of the inner surface of the mounting frame 12. The outer surface of the screw 14 is threadedly connected to the movable seat 15. The rear surface of the movable seat 15 is connected to the scraper 16. The bottom surface of the scraper 16 is in contact with the top surface of the protective top 1. By setting the drive motor 6, its output end can drive the drive gear 7 to rotate during operation. When the drive gear 7 rotates, it can drive the double-acting screw 3 to rotate through the cooperation with the driven gear 4. The two movable plates 2 can move back and forth under the cooperation with the threads on the outer surface of the double-acting screw 3, thereby expanding the rain and sun protection range. Furthermore, by setting the waterproof motor 13, its output end can drive the screw 14 to rotate during operation. When the screw 14 rotates, it can drive the movable seat 15, which is threadedly engaged with it, to move back and forth, thereby driving the scraper 16 to slide along the upper surface of the protective top 1, thereby scraping away the fallen leaves and other debris on its top.
[0026] Please see Figures 1-5 In this embodiment, sliders 8 are installed on both the left and right sides of the two movable plates 2. The movable plates 2 are slidably connected to the protective top 1 through the sliders 8. By setting the sliders 8, the movable plates 2 can slide inside the groove of the protective top 1 when they move, thereby improving the stability of the movable plates 2 when they move. Inclined plates 9 are installed on the ends of the two movable plates 2 away from the bidirectional lead screw 3. The inclined plates 9 are fixed to the movable plates 2 by welding. By setting the inclined plates 9, rainwater can be drained. Two symmetrical support rods 10 are installed in the middle of the bottom surface of the protective top 1. Guide rods 11 are set on the front and rear sides of the outer surface of the two support rods 10. The movable plates 2 are slidably connected to the corresponding guide rods 11. By setting the guide rods 11, the movement direction of the two movable plates 2 can be further restricted, thereby improving stability.
[0027] Please see Figures 1-5In this embodiment, a limiting frame 17 is installed on the rear side of the upper surface of the protective top 1. Limiting rods 18 are installed on the left and right sides of the inner surface of the limiting frame 17. A limiting block 19 is slidably connected through the outer surface of the limiting rod 18. The front surface of the limiting block 19 is connected to the rear end of the scraper 16. By setting the limiting block 19 and the limiting rod 18, the limiting block 19 can slide on the outer surface of the limiting rod 18 when the scraper 16 moves. The limiting rod 18 can restrict the sliding direction of the limiting block 19, thereby improving the stability of the scraper 16 movement. Damping springs 20 are provided at the corners of the bottom surface of the protective top 1. A pad 21 is installed on the surface of the protective top 1. By setting the damping spring 20 and the pad 21, the shock absorption performance of the protective top 1 can be improved. A rain sensor 22 is installed on the top surface of the mounting frame 12. A controller 23 is installed on the right side of the bottom surface of the protective top 1. By setting the rain sensor 22, model FY-PY1, the amount of rainfall can be monitored. The controller 23 controls the operation of the drive motor 6 to automatically adjust the extension length of the movable plate 2. The bottom of the mounting base 5 is fixed to the top of the transformer cabinet with screws. By using screws to fix the mounting base 5, the installation is convenient and the fixing strength is effectively improved.
[0028] During operation, the slider 8 is set to slide inside the groove of the protective top 1 when the movable plate 2 moves, thereby improving the stability of the movable plate 2 during movement. The inclined plate 9 is set to divert rainwater. The guide rod 11 is set to further restrict the movement direction of the two movable plates 2, improving stability. The limit block 19 and the limit rod 18 are set to drive the limit block 19 to slide on the outer surface of the limit rod 18 when the scraper 16 moves. The limit rod 18 can restrict the sliding direction of the limit block 19, thereby improving the stability of the scraper 16 movement. The damping spring 20 and the shim 21 are set to improve the shock absorption performance of the protective top 1. The rain sensor 22, model FY-PY1, is set to monitor the amount of rainfall, thereby controlling the drive motor 6 to operate through the controller 23, thereby automatically adjusting the extension and retraction length of the movable plate 2. The mounting base 5 is fixed with screws, which facilitates installation and effectively improves the fixing strength.
[0029] Through the above steps, by setting the drive motor 6, its output end can drive the active gear 7 to rotate during operation. When the active gear 7 rotates, it can drive the double-acting screw 3 to rotate through the cooperation with the driven gear 4. The two movable plates 2 can move back and forth under the cooperation with the threads on the outer surface of the double-acting screw 3, thereby expanding the rain and sun protection range. Furthermore, by setting the waterproof motor 13, its output end can drive the screw 14 to rotate during operation. When the screw 14 rotates, it can drive the movable seat 15 with its thread cooperation to move back and forth, thereby driving the scraper 16 to slide along the upper surface of the protective top 1, thereby scraping away the fallen leaves and other debris on its top. This solves the problem that the length of the sunshade and rainproof device of the existing transformer sunshade and rainproof device is usually fixed and cannot be retracted or extended, resulting in poor protection effect in summer or rainstorm weather, as well as the problem that it cannot scrape away the debris on the upper surface of the sunshade and rainproof device, and that excessive accumulation of debris can easily lead to structural loosening.
