When the snow accumulation on the roof is thick, the snow removal scraper encounters significant resistance, making the process time-consuming and laborious. Therefore, a high- and low-voltage prefabricated substation is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 A high- and low-voltage prefabricated substation in this embodiment includes a substation body 1 and a substation top cover 2. A compartment 3 is provided on the top of the substation top cover 2. A scraper 4 for scraping snow and a U-shaped cutting plate 5 are movably provided on the substation top cover 2. A first drive mechanism 6 for driving the U-shaped cutting plate 5 to move up and down is provided on the scraper 4. A second drive mechanism 7 for driving the scraper 4 and the U-shaped cutting plate 5 to move horizontally is provided on the right side of the substation body 1.
[0020] The second drive mechanism 7 includes a cover 71, which is fixedly installed on the right side of the chamber 3. Three threaded rods 72 are rotatably installed on the right side of the inner wall of the cover 71. A sprocket 73 is fixedly sleeved on the right end of the outer peripheral wall of the threaded rod 72. The three sprockets 73 are movably connected by a chain 74. A threaded slider 75 is threadedly connected to the outer peripheral wall of the threaded rod 72 and located to the left of the sprocket 73. A motor is fixedly installed on the right side of the cover 71. The output end of the motor passes through the cover 71 and is fixedly connected to the threaded rod 72 above.
[0021] The front and back bottom of the container 3 are provided with sliding holes, which are matched with the scraper 4.
[0022] The three threaded rods 72 are arranged in a triangle inside the cover 71. The upper threaded rod 72 extends into the interior of the chamber 3 and is rotatably connected to the left side of the inner wall of the chamber 3. The lower threaded rod 72 extends to the bottom of the substation top cover 2 and is rotatably connected to the substation top cover 2, so that all three threaded rods 72 can rotate.
[0023] In addition, the upper threaded slider 75 is fixedly connected to one end of both sides of the scraper 4, and the lower threaded slider 75 is fixedly connected to the other end of the scraper 4, so that the threaded slider 75 can drive the scraper 4 to move horizontally.
[0024] Specifically, starting the motor can rotate the upper threaded rod 72. When the upper threaded rod 72 rotates, it drives the sprockets 73 on both sides to rotate synchronously through the chain 74. The sprockets 73 transmit power to the threaded rods 72 on both sides. At this time, the three threaded rods 72 can rotate synchronously. The threaded rods 72, along with the threaded sliders 75, drive the scrapers 4 on both sides to move from right to left.
[0025] In this embodiment, the first drive mechanism 6 includes a housing 61, which is fixedly installed on the top of the scraper 4. A second motor 62 is fixedly installed on the inner side wall of the housing 61 located on the edge of the substation top cover 2. A lead screw 63 is fixedly installed at the output end of the second motor 62. A connecting block 64 is threadedly connected to the outer peripheral wall of the lead screw 63. A connecting plate 65 is fixedly installed on the connecting block 64, one end of which is fixedly connected to the top of the U-shaped cutting plate 5.
[0026] A through hole 66 is provided on the left side of the housing 61, and the connecting block 64 matches the through hole 66.
[0027] The lead screw 63 is rotatably connected to the inner wall of the housing 61 via a bearing, thereby enabling the lead screw 63 to rotate.
[0028] In addition, the connecting block 64 passes through the through hole 66 and extends to the outside of the housing 61, so that the connecting block 64 can move horizontally as the lead screw 63 rotates.
[0029] Specifically, the starter motor 62 can rotate the lead screw 63, and the lead screw 63 drives the connecting block 64 to move the U-shaped cutting plate 5 to perform snow cutting operations.
[0030] In this embodiment, two vertical cutting plates 51 are fixedly installed inside the U-shaped cutting plate 5.
[0031] Among them, a triangular block is provided at one end of the vertical cutting plate 51 near the silo body, thereby reducing the coefficient of friction between the vertical cutting plate 51 and the snow accumulation, and facilitating the movement of the vertical cutting plate 51.
[0032] Specifically, the vertical cutting plate 51 can further divide the snow into smaller pieces, making it easier for the snow blocks to fall off.
[0033] The working principle of the above embodiments is as follows:
[0034] (1) When it is necessary to clear the snow on the top cover 2 of the substation, start the motor to rotate the threaded rod 72 above. When the threaded rod 72 rotates, it drives the sprockets 73 on both sides to rotate synchronously through the chain 74. The sprockets 73 transmit power to the threaded rods 72 on both sides. At this time, the three threaded rods 72 can rotate synchronously. The threaded rods 72 drive the scrapers 4 on both sides to move from right to left with the threaded sliders 75.
[0035] (2) After the scraper 4 moves to the bottom of the snow, the motor 62 is started and the lead screw 63 rotates. The lead screw 63 drives the connecting block 64 to move the U-shaped cutting plate 5 to perform the snow cutting operation. The cut snow blocks fall down along the scraper 4.
[0036] (3) Repeat steps (1) and (2) until the snow on the top cover 2 of the substation is completely cleared. In this way, when clearing snow, the method of cutting and clearing is adopted, which solves the problem that the snow scraper will encounter greater resistance when scraping snow, and the scraping is more time-consuming and laborious, thus achieving the purpose of efficient snow removal.
