As shown in Figures 1 and 2, the present invention provides a distribution box with a protective structure, comprising:

The first support platform 16 is equipped with a power distribution box 12.

The second support platform 25 is raised and lowered around the first support platform 16 through the central perforation. Two pairs of vertical baffles 9 are detachably installed on the second support platform 25 to block the front, back, left and right sides of the distribution box 12 respectively.

The canopy 5 is raised and lowered above the distribution box 12 and detachably connected to the top of the baffle 9. catch.

The distribution box 12 with protective structure provided by this technical solution mainly consists of a first support platform 16 for placing the distribution box 12, a liftable second support platform 25, and a canopy 5 that shields the distribution box 12 from the top. The distribution box 12 is placed on the first support platform 16. The second support platform 25 has a through hole in the middle. The first support platform 16 is inserted into the through hole and is located in the middle of the second support platform 25 along with the distribution box 12. Two pairs of vertical baffles 9 are detachably installed on the second support platform 25. The two pairs of baffles 9 surround the distribution box 12 and shield the front, back, left and right sides of the distribution box 12 to block foreign objects from the surroundings. The canopy 5 is lifted and positioned above the distribution box 12 and is detachably connected to the top of each baffle 9 to prevent foreign objects from the top from directly colliding with the distribution box 12.

The installation process of the distribution box 12 with protective structure provided by this technical solution is as follows: During installation, the first support platform 16 and the second support platform 25 can be placed in the installation pit according to the design position. Then, the distribution box 12 is placed on the first support platform 16. Next, the height of the canopy 5 is adjusted, and each baffle 9 is installed on the second support platform 25 and then connected to the canopy 5. The working principle is as follows: the two pairs of baffles 9 surround the distribution box 12 to prevent foreign objects from the surrounding area from directly colliding with the distribution box 12, and the canopy 5 is located above the distribution box 12 to prevent foreign objects from the top from directly colliding with the distribution box 12.

The present invention has at least the following beneficial effects: a distribution box 12 is provided on a first support platform 16, and a second support platform 25 is raised and lowered around the first support platform 16 through a central perforation. Two pairs of vertical baffles 9 are detachably provided on the second support platform 25 to shield the front, back, left, and right sides of the distribution box 12 respectively. A canopy 5 is raised and lowered above the distribution box 12. The two pairs of baffles 9 surround the distribution box 12, and the canopy 5 is positioned above the distribution box 12, which can effectively block foreign objects from the surroundings and top from directly impacting the distribution box 12, further preventing damage to the distribution box 12 and potential danger. Moreover, compared with the traditional integrated protective room that shields and protects the distribution box, the protective structure of the distribution box 12 in the present invention allows the first support platform 16 and the second support platform 25 to rise and fall relative to each other, the canopy 5 is raised and lowered above the distribution box 12, and the baffles 9 are located around the distribution box 12 and are detachably connected to the second support platform 25 and the canopy 5, making the assembly and disassembly of the protective structure and the distribution box 12 more convenient.

In another technical solution, as shown in Figures 1 and 2, in the distribution box with a protective structure, the first support platform 16 is provided with multiple vertical first support pipes 21 with bottom seals, and a first piston 11 is provided inside the first support pipe 21. The bottom of the second support platform 25 is provided with multiple bottom seals. The vertical support cylinder 18 has its bottom connected to the bottom of its corresponding first support tube 21. A second piston 20 is provided inside the support cylinder 18. The area of the support cylinder 18 connected to the first support tube 21 is filled with a flowable liquid and can push the first piston 11 or the second piston 20 up and down. A vertical support column 19 is provided on the top of the second piston 20.

The bottom of the canopy 5 is provided with multiple vertical first support rods 8, each of which is movably inserted into its corresponding first support tube 21. When the canopy 5 is hit by an object coming from above, the canopy 5 moves downward, pushing the first support rods 8 downward, which in turn pushes the first piston 11 downward. At the same time, the liquid in the first support tube 21 continuously flows into the support cylinder 18, pushing the second piston 20, support column 19, and second support platform 25 upward, weakening the impact force of the object above on the canopy 5. After the object above the canopy is cleared, downward pressure can be applied to the second support platform 25, pushing the support column 19 and second piston 20 downward. At the same time, the liquid in the support cylinder 18 continuously flows into the first support tube 21, causing the first piston 11, first support rods 8, and canopy 5 to rise and return to their original positions.

In another technical solution, as shown in Figure 1, a first spring 10 is provided between the first support rod 8 and the first piston 11 in the distribution box with a protective structure. The first support rod 8 moves downward to compress the first spring 10, which can weaken and buffer the impact force received by the roof.

In another technical solution, as shown in Figures 1 and 2, in the distribution box with a protective structure, the first support platform 16 has multiple support blocks 14 located above the second support platform 25 on its side. Each support block 14 has a first lifting hole, into which an adjusting rod 13 is inserted. The second support platform 25 has a second lifting hole corresponding to the first lifting hole, and below the second lifting hole is the support column 19. The first lifting hole is a threaded hole, and the adjusting rod 13 is a threaded rod. Adjusting the adjusting rod 13 lowers it; after passing through the second lifting hole, the adjusting rod 13 pushes the support column 19 down, which in turn pushes the second piston 20 down. The support blocks 14 support the adjusting rod 13 and also prevent the second support platform 25 from rising excessively.

In another technical solution, as shown in Figure 1, in the distribution box with a protective structure, at the bottom of the canopy 5, the first support rod 8 is fitted with a first limiting tube 6. The top of the first support tube 21 is movably inserted into the first limiting tube 6. A first limiting ring 34 is provided at the bottom of the inner wall of the first limiting tube 6, and a first limiting block 7 is provided at the top of the outer wall of the first support tube 21, located above the first limiting ring 34. The first limiting ring 34 and the first limiting block 7 prevent the canopy 5 from rising excessively and detaching from the first support. Pipe 21.

In another technical solution, as shown in Figure 1, in the distribution box with a protective structure, a second limiting ring 17 is provided on the inner wall of the support cylinder 18, located above the second piston 20. Multiple second springs 15 are arranged between the second limiting ring 17 and the second piston 20. The second piston 20 moves upward to compress the second springs 15, buffering the pressure and assisting in pushing the second piston 20 downward.

In another technical solution, as shown in Figures 1, 2, and 3, in the distribution box with a protective structure, the second support platform 25 is provided with two pairs of lower limit structures, and the bottom of the canopy 5 is provided with two pairs of upper limit structures. The lower limit structures include:

A pair of vertical first lower limit plates 31 are disposed on the second support platform 25, and the first lower limit plates 31 away from the distribution box 12 are detachably connected to the second support platform 25;

A pair of horizontal second lower limit plates 24 are respectively disposed on the top of a pair of first lower limit plates 31 on opposite sides;

A horizontally movable plate 22 is movably disposed between a pair of first lower limit plates 31 and located below the second lower limit plate 24. A lower buffer spring 23 is disposed between the movable plate 22 and the first lower limit plate 31. The baffle 9 is disposed on the movable plate 22 and is movably disposed between the pair of second lower limit plates 24.

The upper limit structure includes:

A pair of vertical first upper limit plates 1 are disposed at the bottom of the canopy 5;

A pair of horizontal buffer slides 2 with opposite openings are respectively set at the bottom of a pair of first upper limit plates 1. A horizontal upper moving plate 3 is movably arranged in the buffer slide 2. An upper buffer spring 4 is arranged between the upper moving plate 3 and the bottom wall of the corresponding buffer slide 2. The top of the baffle 9 is movably clamped between the pair of upper moving plates 3.

In this technical solution, the lower limit structure is used to restrict the position of the bottom of the baffle 9, and the upper limit structure is used to restrict the position of the top of the baffle 9 and to make the baffle 9 detachably connected to the ceiling 5. When the baffle 9 is subjected to physical impacts from all directions, the baffle 9 moves towards the distribution box 12. At the same time, the lower moving plate 22 moves towards the distribution box 12, causing the lower buffer spring 23 on the side closer to the distribution box 12 to be compressed and the lower buffer spring 23 on the side away from the distribution box 12 to be stretched. The upper moving plate 3 on the side closer to the distribution box 12 moves towards the distribution box 12. The upper buffer spring 4 near the distribution box 12 is compressed to buffer and weaken the impact force; after the impact, the upper buffer spring 4 and the lower buffer spring 23 provide the baffle 9 with the power to return to its original position. An appropriate gap is left between the pair of second lower limit plates 24 and between the pair of buffer slides 2 for the baffle 9 to move.

When the second support platform abuts against the top of the support cylinder 18, the adjusting rod 13 continues to descend, pushing the support column 19 and the second piston 20 to descend. At the same time, it pushes the first piston 11, the first support rod 8, and the roof 5 to rise, causing the top of the baffle 9 to slide off between the pair of upper moving plates 3, thus separating the baffle 9 from the roof 5. Then, the first lower limit plate 31 away from the distribution box 12 is removed, and the baffle 9 is moved away from the distribution box 12, so that the baffle 9 can be removed from the second support platform 25.

In another technical solution, as shown in Figures 1, 2, and 4, in the distribution box with a protective structure, the baffles 9 located on the front and rear sides of the distribution box 12 are arc-shaped, and the baffles 9 on the left and right sides of the distribution box 12 are located within the circular area where the baffles 9 on the front and rear sides are located. The baffle 9 on the front side of the distribution box 12 is detachably spliced from a pair of secondary baffles 27. A T-shaped sliding groove 32 is provided on the lower moving plate 22 corresponding to the secondary baffle 27. The bottom of the secondary baffle 27 is T-shaped and is movably disposed within the sliding groove 32. The baffles 9 on the left and right sides of the distribution box 12 are located within the circular area where the baffles 9 on the front and rear sides are located, which facilitates the movement of the front baffle 9. The splicing edge of the primary baffle 27 is provided with a snap-fit groove 28, and the splicing edge of the other secondary baffle 27 is inserted into the snap-fit groove 28 so that the two baffles 27 are spliced together to form the baffle 9. The T-shaped sliding groove 32 prevents the baffle 9 from moving up and down.

In another technical solution, as shown in Figures 2 and 5, in the distribution box with a protective structure, a limiting block 33 and a corresponding horizontal limiting rod 26 are provided on the second support platform near the edge of the lower moving plate 22 corresponding to the secondary baffle 27. One end of the limiting rod 26 is hinged to the second support platform 25, and the other end of the limiting rod 26 is located between the corresponding limiting block 33 and the secondary baffle 27. The position of the limiting rod 26 is higher than the lower moving plate 22. Pulling the other end of the limiting rod 26 causes the limiting rod 26 to rotate around the junction point of one end, and after the rotation angle is greater than 90 degrees, the baffle 27 is pulled in the opposite direction twice. The bottom of the secondary baffle 27 moves along the moving slide 32, creating a certain gap between the two baffles 27, allowing workers to approach the distribution box 12 for maintenance and other operations; the limiting rod 26 prevents the secondary baffle 27 from moving arbitrarily along the moving slide 32.

In another technical solution, as shown in Figures 1, 2, and 3, in the distribution box with a protective structure, a mounting plate 30 is provided at the bottom of the first lower limit plate 31 away from the distribution box 12. The mounting plate 30 is connected to the second platform by screws 29. Assembly and disassembly are flexible and convenient.
