[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0051] like Figures 1 to 11 As shown, the present application proposes a prefabricated substation, including a box body 100, the box body 100 is a rectangular parallelepiped, and also includes a shielding assembly 200, the shielding assembly 200 is used to absorb the surrounding reflected light and reduce the reflected light appearing on the surface of the box body 100; the shielding assembly 200 includes a mounting seat 210, a roller 1 211, a roller 212 and a driving unit 214; the mounting seat 210 is a hollow rectangular parallelepiped inside, fixed to the top of the box body 100, and the area of ​​the mounting seat 210 is not less than the area of ​​the box body 100, that is, the light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121 can block On the outside of the box body 100; there are two rollers 211, which are respectively fixed on both sides of the long side direction of the mounting seat 210, and a light-absorbing cloth 2111 is fixed on the outside of each roller 211, and the light-absorbing cloth 2111 is a black cloth body, which can absorb light, and the light will not be reflected or transmitted, and each light-absorbing cloth 2111 is wrapped around the outside of each roller 211, and a gravity plate 2112 is fixed to the free end of the light-absorbing cloth 2111, and the gravity plate 2112 can move down by its own weight when the light-absorbing cloth 2111 is released;

[0052] There are two rollers 212, which are fixed on both sides of the short side of the mounting seat 210, and a light-absorbing cloth 2121 is fixed on the outside of each roller 212. The light-absorbing cloth 2121 is a black cloth body, which can absorb light without reflecting or transmitting the light. Each light-absorbing cloth 2121 is wrapped around the outside of each roller 212, and a gravity plate 2122 is fixed on the free end of the light-absorbing cloth 2121. The gravity plate 2122 can rely on its own weight when the light-absorbing cloth 2121 is released. Move downward; magnet blocks 120 are fixed on both sides of the long side direction of the bottom of the box body 100, and the magnet block 120 can magnetically attract the gravity plate 2112; magnet blocks 110 are fixed on both sides of the short side direction of the bottom of the box body 100, and the magnet block 110 can magnetically attract the gravity plate 2122; the driving part 214 drives the roller 1 211 and the roller 2 212 to rotate through the motor 213, so that the gravity plate 2112 is magnetically attracted to the magnet block 120, and the gravity plate 2122 is magnetically attracted to the magnet block 110;

[0053] It is easy to understand that the light reflected by the lamp can be absorbed by the light absorbing cloth 1 2111 and the light absorbing cloth 2 2121. At the same time, in hot weather, the light absorbing cloth 1 2111 and the light absorbing cloth 2 2121 can be released to shield the box 100, play a role in absorbing heat, form a layer of protection outside the box 100, and reduce the damage of the high temperature environment to the electrical equipment in the box 100;

[0054] Specifically, if Figure 4 As shown, the driving part 214 includes an active bevel gear 2141 and a driven bevel gear 2142, and a driven bevel gear 2142 is fixed at both ends of each roller wheel 1 211, and a active bevel gear 2141 is fixed at both ends of each roller wheel 212. The active bevel gear 2141 and the driven bevel gear 2142 form a meshing connection. When the active bevel gear 2141 rotates, the driven bevel gear 2142 is driven to rotate, and the meshing connection between the two makes the rotational movement more stable; a driven bevel gear 2142 at one end of the roller wheel 1 211 and an active bevel gear 2141 at one end of the corresponding roller wheel 212 form a group; the two ends of each roller wheel 1 211 and the two ends of each corresponding roller wheel 212 have four groups of active bevel gears 2141 and driven bevel gears 2142, and the output end of the motor 213 is connected to one group of active bevel gears 2141;

[0055] It is easy to understand that the motor 213 drives one group of active bevel gears 2141 to rotate, so that the roller 212 corresponding to the active bevel gears 2141 rotates, and the light-absorbing cloth 2121 is released outward, and at the same time drives the corresponding driven bevel gears 2142 to rotate, so that the roller 1 211 corresponding to the driven bevel gears 2142 rotates, and the light-absorbing cloth 1 2111 is released outward. On the contrary, when the motor 213 rotates in the opposite direction, the light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121 are rewound outside the corresponding roller 1 211 and roller 2 212 again.

[0056] Specifically, if Figure 3 As shown, an electromagnet 2113 is fixed on one side of each of the gravity plates 2112 close to the box 100. When the electromagnet 2113 is powered on, it can generate a magnetic force that attracts the magnet block 120. That is, when the electromagnet 2113 is powered off, it can quickly separate from the magnet block 120, making it convenient to roll up the light-absorbing cloth 2111 on the roller 211.

[0057] Specifically, if Figure 3 As shown, an electromagnet 2123 is fixed on one side of each of the gravity plates 2122 close to the box 100. When the electromagnet 2123 is powered on, it can generate a magnetic force that attracts the magnet block 110. That is, when the electromagnet 2123 is powered off, it can quickly separate from the magnet block 110, making it convenient for the light-absorbing cloth 2121 to be rolled up on the roller 212.

[0058] In the above embodiment, when the light-absorbing cloth 1 2111 is released downward, the electromagnet 1 2113 is energized to make the gravity plate 1 2112 adsorbed on the magnet block 2 120, and when the light-absorbing cloth 2 2121 is released downward, the electromagnet 2 2123 is energized to make the gravity plate 2 2122 adsorbed on the magnet block 1 110, so as to avoid the light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121 from shaking, thereby ensuring the stability of use. After the electromagnet 1 2113 and the electromagnet 2 2123 are powered off, the gravity plate 1 2112 will be separated from the magnet block 2 120, and the gravity plate 2 2122 will be separated from the magnet block 1 110, so that the separation is simple, saving time and effort.

[0059] In some embodiments of the present invention, Figures 1 to 12 As shown, the cleaning component 300 is also included;

[0060] The cleaning assembly 300 includes a fixed seat 310; there are two fixed seats 310, and the two fixed seats 310 are respectively fixed on both sides of the short side direction of the top of the mounting seat 210; a reciprocating screw rod 311 is fixed in each of the fixed seats 310, and the reciprocating screw rod 311 is used to drive the fixed plate 3121 to move, and a reciprocating screw rod 311 and a roller wheel 212 are connected through a transmission part 220. When the roller wheel 212 rotates, the reciprocating screw rod 311 is driven to rotate through the transmission part 220, and a moving block 312 is sleeved on one end of each reciprocating screw rod 311 close to the transmission part 220, and a moving block 312 is threadedly connected to a reciprocating screw rod 311, that is, when the reciprocating screw rod 311 rotates, it can drive the moving block 312 to move;

[0061] The transmission part 220 includes a driven wheel 221 and a driving wheel 222; the driven wheel 221 is fixed on the reciprocating screw rod 311, the driving wheel 222 is fixed on one end of the roller wheel 212, and the driven wheel 221 and the driving wheel 222 are connected by a belt 223;

[0062] Specifically, if Figures 6 to 10 As shown, a fixing plate 3121 is fixed between the two moving blocks 312, a reserved groove is opened on one side of the fixing seat 310 close to the fixing plate 3121, the fixing plate 3121 extends into the reserved groove of the fixing seat 310 and is fixed to the moving block 312, the fixing plate 3121 can be driven by the moving block 312 to move linearly, a scraper 3122 is fixed to the bottom of the fixing plate 3121 close to the mounting seat 210, a dust removal brush 3123 is fixed to the bottom of the scraper 3122, and the dust removal brush 3123 is in contact with the top of the mounting seat 210, so as to facilitate the cleaning of dust and impurities on the mounting seat 210, that is, the top of the box body 100;

[0063] Specifically, if Figure 6 , Fig. 9 and Fig.10 As shown, a guide rod 313 is fixed in each of the fixed seats 310, and a fixed block is fixed on one side of a moving block 312 close to the guide rod 313, and the fixed block is sleeved on the guide rod 313, that is, the moving block 312 is guided and limited by the guide rod 313, so that the moving block 312 will not flip when driven by the reciprocating screw rod 311;

[0064] In the above embodiment, when the roller 212 rotates, the reciprocating screw rod 311 is driven to rotate through the transmission part 220, so that the moving block 312 drives the fixing plate 3121 to move, and the dust on the top of the mounting seat 210 is swept away by the dust removal brush 3123, that is, the dust on the top of the box body 100 is removed, and some fallen branches or large-diameter stones can be swept away at the same time, without manually looking for tools to sweep them away, and the snow on the top can be swept away in the cold winter, reducing the danger of manual cleaning with the help of tools such as ladders, and preventing the water after the melted snow from entering the box body 100;

[0065] In some embodiments of the present invention, Figures 5 to 10 As shown, a collecting box 330 is fixed on one side of the long side of the mounting seat 210. The collecting box 330 is used to collect scraped impurities so that the impurities will not splash around and are easy to clean. A cover plate 321 is fixed on the top of the collecting box 330. The cover plate 321 can prevent foreign impurities from entering the collecting box 330. A fixing frame 320 is fixed on the free end of each of the moving blocks 312. A through groove is opened on one side of the fixing seat 310 close to the fixing frame 320. The fixing frame 320 extends into the through groove of the fixing seat 310 and is connected to the moving block 312. One end of the fixing frame 320 is fixedly connected to the cover plate 321.

[0066] Specifically, if Figures 5 to 10 As shown, a limiting frame 331 is fixed to one side of the top of the collecting box 330 near the mounting seat 210, and the side of the cover plate 321 contacts the limiting frame 331, that is, the cover plate 321 can be limited by the limiting frame 331, and when the reciprocating screw rod 311 drives the scraper 3122 to move, the cover plate 321 moves accordingly, and when the reciprocating screw rod 311 drives the scraper 3122 to reset, the cover plate 321 is reset synchronously and finally contacts the limiting frame 331. By observing whether the cover plate 321 contacts the limiting frame 331, it can be judged whether each component is accurately reset.

[0067] In the above embodiment, the moving fixing frame 320 of the moving block 312 can move synchronously therewith, and the cover plate 321 is removed from the collection box 330, so that the collection box 330 does not need to be opened and closed manually, and the scraped dust, solid impurities and snow can enter the collection box 330, which is convenient for cleaning;

[0068] In some embodiments of the present invention, Figures 11 to 13 As shown, the collecting box 330 is a rectangular box with a hollow interior and openings at the top and bottom. A limiting plate 333 is positioned at the opening at the bottom of the collecting box 330. The limiting plate 333 is used to carry the scraped impurities. Two slide grooves 332 are opened at the edge of the bottom of the collecting box 330. A discharge box 340 is positioned below the collecting box 330. Two slide plates 341 are fixed on the top of the discharge box 340. One slide plate 341 extends into one slide groove 332.

[0069] It is easy to understand that when there are a lot of materials collected in the collection box 330, the discharge box 340 is slidably installed at the bottom of the collection box 330, and then the limit plate 333 is pulled to expose the opening at the bottom of the collection box 330, and the collected materials will fall into the discharge box 340, and then the discharge box 340 can be removed.

[0070] When the prefabricated substation of the embodiment of the present application is actually used,

[0071] First, the motor 213 is used to drive one group of active bevel gears 2141 to rotate, so that the corresponding driven bevel gears 2142 rotate synchronously, driving the two rollers 1 211 and the two rollers 212 to rotate, and the corresponding light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121 are released downwards. At the same time, the electromagnet 1 2113 and the electromagnet 2 2123 are energized. When the gravity plate 1 2112 approaches the magnet block 2 120, the electromagnet 1 2113 will be magnetically attracted to the magnet block 2 120. Similarly, the electromagnet 2 2123 will be magnetically attracted to the magnet block 1 110, so as to position the light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121, and reduce the approach of insects with positive phototropism.

[0072] As the rotating transmission part 220 of the roller 212 starts to drive the reciprocating screw 311 to perform synchronous rotational motion, the moving block 312 performs linear motion under the rotation of the reciprocating screw 311, and the moving block 312 drives the scraper 3122 and the fixing frame 320 to move, and the fixing frame 320 is used to open the cover 321, and the dust removal brush 3123 sweeps the dust on the top of the box 100 into the collection box 330, and the scraper 3122 can be used to sweep away the snow on the top of the box 100, and the dust, impurities and snow on the top of the box 100 are scraped into the collection box 330;

[0073] When the light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121 are rolled up and reset, the electromagnet 1 2113 and the electromagnet 2 2123 are powered off, so that the gravity plate 1 2112 is separated from the magnet block 2 120, and the gravity plate 2 2122 is separated from the magnet block 1 110. Then, the motor 213 drives the active bevel gear 2141 to rotate in the opposite direction, so that the light-absorbing cloth 1 2111 and the light-absorbing cloth 2 2121 are gradually rolled up onto the roller 1 211 and the roller 2 212. At the same time, the reciprocating screw rod 311 is driven to rotate in the opposite direction, so that the scraper 3122 moves in the opposite direction and resets, and at the same time drives the cover plate 321 to reset, so as to prevent foreign objects from falling into the collection box 330.

[0074] The present invention can shield and protect the box body 100 by setting up the shielding component 200 and the cleaning component 300, reduce the situation where the reflected light at the box body 100 attracts insects, and can clean the dust and impurities on the top of the box body 100. It can also handle the snow on the top of the box body 100 in the cold winter to keep the box body 100 clean and beautiful. At the same time, it is convenient to clean the collected impurities, the operation is simple, and it saves time and effort.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
