Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and in particular to a ventilation and moisture-proof structure for prefabricated substations. Background Technology

[0002] Prefabricated substations, also known as box-type substations, are a type of substation that organically combines transformer voltage reduction and low-voltage power distribution functions. They are compact, prefabricated indoor and outdoor power distribution equipment, particularly suitable for urban power grid construction and renovation. They represent a new type of substation that has emerged after traditional civil engineering substations. Box-type substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system.

[0003] Most existing prefabricated substations only meet basic ventilation requirements and lack efficient dehumidification functions. This allows moisture from the external environment to easily penetrate into the substation, affecting the normal operation of internal electrical components and seriously threatening the stability and safety of the system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a ventilation and moisture-proof structure for prefabricated substations.

[0005] This utility model provides a ventilation and moisture-proof structure for a box-type substation, comprising: a substation body; a ventilation and moisture-proof component, the ventilation and moisture-proof component including a ventilation pipe, a bidirectional fan, a drying box, a mesh plate, and a heating wire, the ventilation pipe being fixedly installed through one side of the substation body, the bidirectional fan being fixedly installed inside the ventilation pipe, the drying box being abutted against the inner wall of the ventilation pipe, the drying box being filled with a desiccant, one end of the mesh plate being fixedly connected to a hinge, the other end of the hinge being fixedly installed on the ventilation pipe, and the heating wire being fixedly installed on the inner side of the mesh plate; and a dustproof component, the dustproof component being used to isolate external dust, the dustproof component including a positioning frame and a dustproof net, the positioning frame being slidably fitted onto the outer end of the ventilation pipe, the dustproof net being fixedly installed inside the positioning frame, and a magnetic block being fixedly installed inside the positioning frame.

[0006] Furthermore, a spring plate is fixedly installed at the bottom of the ventilation pipe, and a locking block is fixedly installed on the spring plate, with the outer side of the locking block being inclined.

[0007] Furthermore, a cover plate is rotatably connected to the top of the drying box, a limiting frame is fixedly installed inside the ventilation pipe, the drying box abuts against the limiting frame, and multiple top posts are fixedly installed on the inner side of the mesh plate, the top posts abutting against the drying box.

[0008] Furthermore, a humidity sensor and a controller are fixedly installed inside the substation body.

[0009] Furthermore, a ventilation hole is provided through one side of the substation body, and a filter screen is fixedly installed inside the ventilation hole.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. A ventilation and moisture-proof component is installed. During use, the bidirectional fan can achieve ventilation through the ventilation pipe and ventilation hole; the desiccant in the drying box can absorb moisture in the air, reduce the humidity of the air, ensure the stable operation of the internal components of the substation, and improve stability and safety; the heating wire can heat the desiccant to promote the evaporation of its internal moisture, and the moisture can be discharged by the bidirectional fan, reducing the moisture in the desiccant, enhancing its dehumidification efficiency, avoiding frequent desiccant replacement, and reducing the cost of use.

[0012] 2. A dustproof component is installed. The dustproof net can isolate external dust and avoid affecting the temperature operation of internal components. The positioning frame can be magnetically attached to the outer end of the ventilation duct. The positioning frame can be removed by separating the magnetic block from the ventilation duct, making it easy to clean or replace the dustproof net, avoiding blockage and affecting the ventilation effect, and increasing practicality.

[0013] In summary, this utility model incorporates a ventilation and moisture-proof component, which ensures ventilation while reducing air humidity, thus improving stability and safety. It also allows for the drying and recycling of the desiccant, reducing operating costs. Furthermore, a dustproof component provides dust protection while allowing for easy disassembly and cleaning of the dustproof net, enhancing its practicality. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a ventilation and moisture-proof structure for a box-type substation, including: a substation body 1, with a ventilation hole 16 extending through one side of the substation body 1 for heat dissipation; a filter screen is fixedly installed inside the ventilation hole 16 for dust removal; a humidity sensor 18 and a controller 17 are fixedly installed inside the substation body 1, and the controller 17 is electrically connected to the humidity sensor 18, the bidirectional fan 3, and the heating wire 12. The humidity sensor 18 is responsible for detecting the humidity of the air inside the substation body 1 and then transmitting the acquired humidity data to the controller 17. The controller 17 is responsible for receiving the humidity data from the humidity sensor 18 and controlling the airflow direction of the bidirectional fan 3 based on this data, and can also control the opening and closing of the heating wire 12. The humidity sensor 18 and the controller 17 are both within the scope of existing mature technology, and therefore will not be described in detail.

[0020] The ventilation and moisture-proof component includes a ventilation duct 2, a bidirectional fan 3, a drying box 4, a mesh plate 7, and a heating wire 12. The ventilation duct 2 is fixedly installed through one side of the substation body 1. The bidirectional fan 3 is fixedly installed inside the ventilation duct 2. The bidirectional fan 3 is an existing mature technology that controls the rotation direction of the motor by changing the current flow, thereby realizing the reversal of the fan's airflow direction.

[0021] The drying box 4 adopts a mesh structure design to ensure that air can smoothly penetrate and enter the interior of the drying box 4; the drying box 4 is set against the inner wall of the ventilation pipe 2, thereby limiting the position of the drying box 4; the drying box 4 is filled with desiccant, which is used to absorb moisture in the air; a cover plate 5 is rotatably connected to the top of the drying box 4, which is used to cover the top of the drying box 4. The cover plate 5 fits against the inner top of the ventilation pipe 2, thereby preventing the desiccant from escaping; a limiting frame 6 is fixedly installed inside the ventilation pipe 2, and the drying box 4 is set against the limiting frame 6, which is used to limit the position of the drying box 4;

[0022] The mesh plate 7 is used to cover the inner side of the ventilation duct 2. One end of the mesh plate 7 is fixedly connected to a hinge 8, and the other end of the hinge 8 is fixedly set on the ventilation duct 2, so that the mesh plate 7 can rotate through the hinge 8. Multiple top posts 9 are fixedly set on the inner side of the mesh plate 7. The top posts 9 are set against the drying box 4. The top posts 9 are used to press the drying box 4 tightly, thereby fixing the drying box 4.

[0023] A spring plate 10 is fixedly installed at the bottom of the ventilation pipe 2, and a locking block 11 is fixedly installed on the spring plate 10. The locking block 11 can lock the mesh plate 7. The outer side of the locking block 11 is set with an inclined surface, so that squeezing the inclined surface of the locking block 11 can push the locking block 11 downward and bend the spring plate 10.

[0024] After prying the locking block 11 downwards to separate it from the mesh plate 7, the mesh plate 7 can be opened, and the drying box 4 can be taken out. The cover plate 5 can then be opened to replace the desiccant inside. After replacement, the cover plate 5 is closed, and the drying box 4 is placed into the ventilation pipe 2 and abutted against the limiting frame 6. Finally, the mesh plate 7 is closed, and the inclined surface of the locking block 11 is pressed down to push it downwards and bend the spring plate 10. When the mesh plate 7 moves into the locking block 11, the locking block 11 can be reset under the action of the spring plate 10, thereby locking the mesh plate 7. At the same time, the drying box 4 is pressed tightly by the top column 9 to complete the replacement.

[0025] Heating wire 12 is fixedly installed on the inner side of mesh plate 7. Heating wire 12 is located close to drying box 4 and is used to heat the desiccant in drying box 4 to remove moisture from the desiccant.

[0026] The dustproof component is used to isolate external dust. The dustproof component includes a positioning frame 13 and a dustproof net 14. The positioning frame 13 is slidably sleeved on the outer end of the ventilation pipe 2. The dustproof net 14 is fixedly installed inside the positioning frame 13. A magnetic block 15 is fixedly installed inside the positioning frame 13.

[0027] The ventilation duct 2 is made of magnetic metal, so that the magnetic block 15 can be attracted and fixed to the ventilation duct 2, thereby fixing the positioning frame 13 and the dustproof net 14. The positioning frame 13 is pulled out, so that the magnetic block 15 is separated from the ventilation duct 2, and the dustproof net 14 can be removed for cleaning or replacement to avoid blockage and affect the ventilation effect.

[0028] In use, the bidirectional fan 3 blows outside air into the substation body 1 through the ventilation pipe 2, and finally blows it out through the ventilation hole 16. During this process, the desiccant in the drying box 4 absorbs moisture from the air entering the substation body 1, reducing the humidity and ensuring the stable operation of the internal components of the substation body 1. When the humidity inside the substation body 1 decreases due to the reduced dehumidification effect of the desiccant, the humidity sensor 18 detects this change and identifies that the humidity is at a low level. Subsequently, through the action of the controller 17, the bidirectional fan 3 can be instructed to adjust the airflow direction, and at the same time, the heating wire 12 is activated to heat the desiccant, causing the moisture in the desiccant to evaporate. At this time, the bidirectional fan 3 uses the ventilation pipe 2 to discharge the evaporated moisture, effectively reducing the moisture content in the desiccant, thereby enhancing its dehumidification efficiency. When the moisture in the desiccant has been fully dissipated, the controller 17 will turn off the heating wire 12 in time and restore the airflow direction of the bidirectional fan 3 to its original position.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
