Description

Technical Field

[0001] The utility model relates to the technical field of dust-proof net disassembly, in particular to a box-type substation with a conveniently detachable dust-proof net. Background Technique

[0002] A box-type substation, also known as a prefabricated substation or prefabricated transformer substation, is a factory prefabricated indoor and outdoor compact power distribution equipment that combines high-voltage switchgear, distribution transformers, and low-voltage distribution devices according to a certain wiring scheme.

[0003] In the prior art, the dust-proof net of the box-type substation is often designed to be vertically fixed. However, since the dust-proof net needs to cover a large area to effectively block dust from entering the substation, it is often large in size. When the dust-proof net needs to be cleaned or replaced due to long-term use, its vertically fixed state greatly increases the difficulty of disassembly. When the staff tries to disassemble it, they need to face the strong resistance generated by the self-weight and area of the dust-proof net. This not only requires the staff to have high operation skills but also increases the safety risks during the operation. And because the dust-proof net is vertically installed, it is not easy to control the disassembly direction and speed. If care is not taken, the dust-proof net may fall off or be damaged, which will have an adverse impact on the surrounding environment and equipment of the substation.

[0004] Therefore, we have proposed a box-type substation with a conveniently detachable dust-proof net to solve the above problems. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present invention provides a box-type substation with a conveniently detachable dust-proof net, which solves the problems raised in the above background technique.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A box-type substation with a conveniently detachable dust-proof net includes a substation body. Symmetrically fixed to the side wall of the substation body are sliding rails. Sliding blocks are slidably connected within the sliding rails. A rotating shaft is rotatably connected between the sliding blocks. Fixed to the center of the outer surface of the rotating shaft is an installation frame. Fixed within the installation frame is a net body.

[0008] As a further scheme of the utility model: Arc-shaped grooves are respectively formed on one side of the sliding blocks close to the installation frame. Limit posts are slidably connected within the arc-shaped grooves. One end of each limit post away from the arc-shaped groove is fixedly connected to a connection block. The connection blocks are all fixedly connected to the outer surface of the rotating shaft.

[0009] As a further solution of the utility model: a cross plate is fixedly connected to one side of the installation frame, grooves are symmetrically formed on the side of the cross plate away from the net body, moving blocks are slidably connected in the grooves, vertical plates are fixedly connected to the moving blocks, handles are fixedly connected to the sides of the vertical plates away from the moving blocks, clamping columns are symmetrically and fixedly connected to the opposite sides of the vertical plates, fixing blocks are slidably connected to the outer surfaces of the clamping columns, the fixing blocks are fixedly connected to the side walls of the installation frame, limiting blocks are symmetrically and fixedly connected to the side of the substation body close to the installation frame, and the upper clamping columns are all inserted and connected to the limiting blocks.

[0010] As a further solution of the utility model: support plates are fixedly connected to the upper end faces of the slide rails, and the lower clamping columns are all inserted and connected to the support plates.

[0011] As a further solution of the utility model: return springs are fixedly connected to the opposite sides of the moving blocks, and the ends of the return springs away from the moving blocks are fixedly connected to the inner walls of the grooves.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. Through the arranged rotating shaft, arc-shaped groove and limiting column, during the process of the staff disassembling the net body, the net body can be rotated and adjusted from a vertical state to a horizontal state, so that the direction of the gravity of the net body changes and no longer directly acts on the disassembly point, thereby significantly reducing the resistance that the staff needs to overcome, making the disassembly process smoother, and the net body in the horizontal state is also easier to control its disassembly direction and speed.

[0014] 2. Through the arranged clamping columns, limiting blocks and support plates, the installation frame can be stably clamped to the substation body. Different from the existing technology of using bolts for fixation, it not only facilitates the staff to disassemble, simplifies the disassembly process, enables the staff to not need to use special tools (such as wrenches, screwdrivers, etc.) to loosen or tighten bolts, and only needs simple operations to realize the quick disassembly and installation of the installation frame, thereby improving work efficiency and reducing the problems of bolt wear and loosening caused by frequent disassembly, but also through the clamping method, it can ensure the close fit between the installation frame and the substation body, reduce the gaps or looseness caused by improper installation, thereby further improving the stability and bearing capacity of the installation frame, and ensuring that the net body will not fall off or be damaged due to vibration or external forces during use.

Specific implementation mode

[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment:

[0024] As Figures 1-5 shown, a dust-proof net detachable box-type substation includes a substation body 1, slide rails 4 are symmetrically and fixedly connected to the side walls of the substation body 1, sliders 5 are slidably connected in the slide rails 4, a rotating shaft 18 is rotatably connected between the sliders 5, and an installation frame 3 is fixedly connected to the center of the outer surface of the rotating shaft 18, and a mesh body 2 is fixedly connected in the installation frame 3.

[0025] In this embodiment, as Figure 5 shown, arc grooves 16 are respectively formed on one side of the sliders 5 close to the installation frame 3, limiting columns 17 are slidably connected in the arc grooves 16, connecting blocks 19 are fixedly connected to one ends of the limiting columns 17 far away from the arc grooves 16, and the connecting blocks 19 are fixedly connected to the outer surface of the rotating shaft 18. By limiting the limiting columns 17 through the arc grooves 16 provided, the rotating shaft 18 can only rotate 90 degrees between the two sliders 5, driving the installation frame 3 to move between the vertical and horizontal states.

[0026] In this embodiment, as Figure 2As shown in the figure, a cross plate 6 is fixedly connected to one side of the installation frame 3. Grooves 12 are symmetrically formed on the side of the cross plate 6 away from the net body 2. Moving blocks 13 are slidably connected in the grooves 12. Vertical plates 7 are fixedly connected to the moving blocks 13. Handles 15 are fixedly connected to the sides of the vertical plates 7 away from the moving blocks 13. Columns 8 are symmetrically and fixedly connected to the opposite sides of the vertical plates 7. Fixed blocks 9 are slidably connected to the outer surfaces of the columns 8. The fixed blocks 9 are fixedly connected to the side walls of the installation frame 3. Limit blocks 10 are symmetrically and fixedly connected to the side of the substation body 1 close to the installation frame 3. The upper columns 8 are all inserted and connected to the limit blocks 10. Through the mutual clamping of the columns 8 and the limit blocks 10, after the installation frame 3 drives the net body 2 to move to a vertical state, the vertical state of the net body 2 and the installation frame 3 can be maintained, and the net body 2 and the installation frame 3 can be fixed on the side wall of the substation body 1.

[0027] In this embodiment, as Figure 2 shown, support plates 11 are fixedly connected to the upper end faces of the slide rails 4. The lower columns 8 are all inserted and connected to the support plates 11. By clamping the lower columns 8 on the support plates 11, the installation stability of the installation frame 3 and the net body 2 on the side wall of the substation body 1 can be further increased.

[0028] In this embodiment, as Figure 3 shown, return springs 14 are fixedly connected to the opposite sides of the moving blocks 13. One ends of the return springs 14 away from the moving blocks 13 are fixedly connected to the inner walls of the grooves 12. When the moving blocks 13 are forced to slide in the grooves 12, the return springs 14 will be compressed. When the force on the moving blocks 13 disappears, the moving blocks 13 can be pushed back to the initial position by the rebounding force of the return springs 14.

[0029] The effects achieved by this embodiment are as follows: In the prior art, since the dust-proof net needs to cover a large area to effectively block dust from entering the substation, it is often large in size. When the dust-proof net needs to be cleaned or replaced due to long-term use, its vertically fixed state greatly increases the difficulty of disassembly. When the staff tries to disassemble it, they need to face the strong resistance generated by the self-weight and area of the dust-proof net. This not only requires the staff to have high operation skills but also increases the safety risks during the operation. And because the dust-proof net is vertically installed, it is not easy to control its disassembly direction and speed. If not careful, the dust-proof net may fall off or be damaged, which will have an adverse impact on the surrounding environment and equipment of the substation. Compared with the prior art, during the disassembly process of the net body 2 by the staff, the net body 2 can be rotated and adjusted from a vertical state to a horizontal state, so that the direction of gravity of the net body 2 changes and no longer directly acts on the disassembly point, thus significantly reducing the resistance that the staff needs to overcome and making the disassembly process smoother. And the net body 2 in the horizontal state is also easier to control its disassembly direction and speed.

[0030] The working process and principle involved in the overall content of the above embodiments are as follows:

[0031] When the staff needs to disassemble the net body 2 from the substation body 1 for cleaning, repair or replacement, first pull the handles 15 on both sides. Since the moving block 13 is slidably connected to the groove 12, pulling the vertical plates 7 on both sides to slide closer to each other on the side wall of the cross plate 6. During the process of the vertical plates 7 approaching each other, the clamping columns 8 connected to the opposite sides of the vertical plates 7 can be driven to move synchronously, so that the clamping columns 8 slide out of the limiting blocks 10 and the support plates 11 respectively. After the clamping columns 8 completely slide out of the limiting blocks 10 and the support plates 11, the staff can pull the installation frame 3 to drive the net body 2 to be disassembled from the substation body 1, simplifying the disassembly process. The staff does not need to use special tools (such as wrenches, screwdrivers, etc.) to loosen or tighten bolts, and only needs to perform simple operations to achieve the quick disassembly and installation of the installation frame 3, thereby improving work efficiency and reducing the problems of bolt wear and loosening caused by frequent disassembly. Moreover, through the clamping method, it can ensure the close fit between the installation frame 3 and the substation body 1, reducing the gaps or looseness caused by improper installation, thereby further improving the stability and load-bearing capacity of the installation frame 3, and ensuring that the net body 2 will not fall off or be damaged due to vibration or external forces during use;

[0032] During the process of pulling the installation frame 3 away from the substation body 1, the installation frame 3 will rotate between the two sliders 5 through the rotating shaft 18. As the rotating shaft 18 rotates, the rotating shaft 18 will drive the limiting column 17 to slide in the arc-shaped groove 16 opened on the side wall of the slider 5 through the connecting block 19 connected to the outer surface. Due to the limitation of the limiting column 17 by the arc-shaped groove 16, after the installation frame 3 rotates from the vertical state to the horizontal state, the installation frame 3 and the net body 2 will be kept in the horizontal state, thus significantly reducing the resistance that the staff needs to overcome, making the disassembly process smoother, and the net body 2 in the horizontal state is also easier to control its disassembly direction and speed;

[0033] When the staff needs to completely disassemble the installation frame 3 and the net body 2 from the substation body 1, after the installation frame 3 and the net body 2 rotate to the horizontal state, the staff can horizontally pull the installation frame 3 to drive the slider 5 to slide on the slide rail 4. When the slider 5 slides out of the inside of the slide rail 4, the installation frame 3 and the net body 2 will be separated from the substation body 1.
