Outdoor protection type box-type substation

Abstract

The invention relates to an outdoor protective box-type substation, which relates to the technical field of box-type substations and comprises a box body, a box door hinged to the box body and a box cover covering the top of the box body. A plurality of heat dissipation openings are formed in the opposite vertical side faces of the box body, protective covers with downward openings are fixedly arranged on the outer side opening edges of the heat dissipation openings, and drainage covers with upward openings are fixedly arranged on the inner side opening edges of the heat dissipation openings. According to the invention, the protective cover can shield most of rainwater falling from the side surface and prevent the rainwater from directly entering the heat dissipation opening, so that the risk of rainwater permeation is greatly reduced. Meanwhile, due to the design of the drainage cover, when rainwater infiltrates accidentally, water flow can be guided to flow out upwards along the cover body, and the water flow is prevented from making contact with electrical elements in the box body. The dual protection mechanism not only guarantees the heat dissipation requirement of the box-type substation, but also remarkably improves the rainproof performance of the box-type substation, and ensures the stable operation of equipment under severe weather conditions.

Description

Technical Field

[0001] The present application relates to the technical field of box-type substations, and in particular to an outdoor protective box-type substation. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a compact power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment. It organically combines the functions of transformer step-down and low-voltage power distribution, housed in a fully enclosed steel structure box that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, and heat-insulated.

[0003] Existing outdoor box-type substation designs typically include a box body divided into high-voltage, low-voltage, and transformer compartments, with hinged doors to accommodate the installation of various electrical components. To ensure necessary heat dissipation during equipment operation, cooling vents are provided on the side walls of the box.

[0004] When this type of equipment is deployed in coastal areas with high rainfall, particularly during the summer rainy season, a significant technical challenge arises: while the heat dissipation vents within the enclosure help dissipate heat from internal electrical components, they can also serve as pathways for rainwater to penetrate. Once rainwater enters the enclosure through these openings, it can not only affect the proper functioning of electrical components and degrade system performance, but in extreme cases, it can also cause electrical shorts and lead to safety incidents. This poses a serious threat to the long-term stable operation of the equipment, leaving room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an outdoor protective box-type substation to solve the rainwater protection problem of the box-type substation in the above-mentioned coastal rainy areas.

[0006] The outdoor protective box-type substation provided in this application adopts the following technical solutions: An outdoor protective box-type substation comprises a box body, a box door hinged on the box body, and a box cover arranged on the top of the box body; a plurality of heat dissipation openings are opened on the opposite vertical sides of the box body, a protective cover with an opening facing downward is fixed on the outer opening edge of the heat dissipation opening, and a drainage cover with an opening facing upward is fixed on the inner opening edge of the heat dissipation opening.

[0007] By adopting the above technical solution, a protective cover with a downward opening is set on the outside of the heat dissipation port of the box body, and a drainage cover with an upward opening is set on the inside of the heat dissipation port, which effectively solves the rain protection problem faced by box-type substations in rainy coastal areas. The protective cover can block most of the rainwater falling from the side, preventing it from directly entering the heat dissipation port, thereby greatly reducing the risk of rainwater penetration. At the same time, the design of the drainage cover can guide the water flow upward along the cover body when rainwater accidentally seeps in, preventing it from contacting the electrical components in the box body. This dual protection mechanism not only guarantees the heat dissipation needs of the box-type substation, but also significantly improves its rainproof performance, ensuring the stable operation of the equipment under adverse weather conditions.

[0008] Optionally, a cover plate is provided in the box body horizontally above the drainage hood, and vertical rods are vertically fixed at both ends of the cover plate, and the vertical rods are slid on the inner wall of the box body; a driving part is provided on the inner wall of the box body to drive the vertical rod to slide downward to block the drainage hood opening, and a reset part is provided to slide upward to release the blockage of the drainage hood.

[0009] By adopting the above technical solution, the cover plate arranged horizontally in the box body can slide on the inner wall of the box body through the vertical rods at both ends, realizing the flexible blocking and opening of the drainage cover. When the outside rain is heavy, the driving member can drive the vertical rods and cover plate to slide downward, quickly blocking the drainage cover opening, effectively preventing rainwater from invading the interior of the box body through the heat dissipation vents. When the weather improves and the rain decreases, the reset member drives the cover plate and vertical rods to slide upward, releasing the blockage of the drainage cover and restoring the normal heat dissipation function of the box body. This design not only improves the automation level of the box-type substation, but also ensures its stable operation under different weather conditions.

[0010] Optionally, the reset member includes a spring, a guide block fixed on the inside of the box, and a baffle fixed on the outer periphery of the vertical rod, the guide block is located below the baffle, and the two ends of the spring are respectively fixedly connected to the side surfaces of the baffle and the guide block close to each other.

[0011] With this technical solution, once the cover and vertical rods move downward under the action of the driver to block the drainage hood, the spring begins to accumulate force. Once the driver stops, the spring's elastic force pushes the baffle and vertical rods upward, thereby returning the cover to its original position and releasing the blockage from the drainage hood. The guide block design ensures the stability and accuracy of the vertical rods during movement, preventing them from deviating from their intended trajectory. This reset mechanism is not only simple in structure and easy to maintain, but also rapidly responds to external changes, ensuring the stable operation of the box-type substation.

[0012] Optionally, the driving member includes a horizontally arranged connecting rod and an electric cylinder located above the connecting rod, the two ends of the connecting rod are fixedly connected to the upper ends of the two vertical rods, the electric cylinder is fixed on the inner wall of the box along the horizontal direction, and a vertical downward push rod is fixed on the outer periphery of the telescopic rod of the electric cylinder; a vertical upward adjustment rod is fixed in the middle of the upper side of the connecting rod, and a guide slope is provided on the end edge of the adjustment rod; the push rod can squeeze the adjustment rod downward along the guide slope when sliding with the telescopic rod on the electric cylinder.

[0013] By adopting this technical solution, the electric cylinder serves as the power source, and its telescopic rod, through the push rod and the adjustment rod on the connecting rod, precisely controls the vertical movement of the cover. The guiding bevel at the end of the adjustment rod allows the push rod to smoothly push the adjustment rod downward along the bevel as it slides with the electric cylinder's telescopic rod, thereby driving the connecting rod and vertical rod downward to seal the drainage cover opening. This design not only improves the automation level of the box-type substation, but also ensures the accuracy and stability of the sealing action. Furthermore, by adjusting the extension and extension stroke and speed of the electric cylinder, it can flexibly adapt to the rain protection requirements in different weather conditions, providing a strong guarantee for the long-term and stable operation of the box-type substation.

[0014] Optionally, a protective plate is hinged on the lower edge of the side of the box cover facing the box door, an extension rod is coaxially fixed to the end of the telescopic rod on the electric cylinder, and a positioning hole for the extension rod to pass through is provided on the side of the box body facing the protective plate; the outer end of the extension rod is hinged with a connecting block, and the connecting block is slidably connected to the side away from the extension rod and the inner side of the protective plate; when the extension rod slides back and forth with the telescopic rod on the electric cylinder, it drives the protective plate to rotate through the connecting block.

[0015] By adopting this technical solution, the protective plate can be quickly rotated to a vertical position in rainy or humid environments, effectively blocking the intrusion of rain and moisture, and protecting the normal operation of the electrical equipment within the box-type substation. In sunny or dry weather, the protective plate can be rotated to a diagonal downward angle to avoid interfering with the normal opening of the box door while maintaining a certain degree of protection. This design not only improves the automation level of the box-type substation, but also enhances its ability to adapt to different environmental conditions, providing a strong guarantee for the stable operation of the power system.

[0016] Optionally, an observation window is fixed on the box door, and a fixed block is slidably provided in the horizontal direction on the inner side surface of the protective plate, and cleaning cotton is fixed on the fixed block; the protective plate can be rotated downward to a vertical state and fixed, and the cleaning cotton can fit with the outer side surface of the observation window when the protective plate is in this state, and the cleaning cotton synchronously cleans the outside of the observation window when the fixed block slides back and forth.

[0017] By adopting this technical solution, when the protective plate is rotated to the vertical position, the cleaning cotton on the fixed block can be tightly attached to the outer surface of the observation window. By sliding the fixed block, the cleaning cotton can easily wipe away dust and stains on the surface of the observation window, maintaining a clear field of vision. This design not only avoids the danger and inconvenience of manual wiping, but also greatly improves cleaning efficiency and quality.

[0018] Optionally, a traction rod is hinged to the lower end of the fixing block, and the fixing block can be slidably adjusted by the traction rod.

[0019] By adopting this technical solution, workers can conveniently slide and adjust the fixed block and the cleaning cotton on it by holding and pulling the traction rod, achieving comprehensive and uniform cleaning of the exterior of the observation window. This design not only improves cleaning efficiency but also reduces operational difficulty, making cleaning work more time-saving and labor-saving.

[0020] Optionally, a dovetail slide rail is fixedly provided on the inner side of the protective plate in the horizontal direction, and a dovetail slide groove is provided on the fixed block for the dovetail slide rail to slide into; elastic clips are provided on the outer periphery of both ends of the dovetail slide rail, and a positioning groove is provided on the inner wall of the dovetail slide groove for the elastic clip to be inserted into.

[0021] By adopting the above technical solution, the coordinated design of the dovetail rail and dovetail groove ensures the stability and accuracy of the fixed block during sliding, preventing shaking or deviation, thereby improving cleaning results. At the same time, the engagement of the elastic clip with the positioning groove ensures that the fixed block can be firmly positioned after sliding to the desired position, preventing accidental sliding due to external forces, and ensuring the safety and reliability of cleaning operations.

[0022] Optionally, a blocking plate is fixedly provided on the inner wall of the opening of the protective cover, and a blocking through-hole is provided on the blocking plate. Several blocking plates are slidably provided in the horizontal direction on the outer edges of the openings of the protective cover, and the blocking through-holes are provided on the blocking plates; a support rod is commonly fixed on the side of the several blocking plates facing the box door, and the end of the traction rod away from the fixed block is detachably hinged to the outer peripheral surface of the support rod; during the rotation process, the protective plate drives the blocking plate to slide back and forth through the traction rod to control the misalignment or overlap of the blocking through-hole and the blocking through-hole.

[0023] By adopting the above technical solution, during the rotation of the protective plate, the traction rod not only drives the fixed block and the cleaning cotton on it to clean the observation window, but also synchronously drives the blocking plate to slide on the opening of the protective cover, thereby accurately controlling the misalignment or overlap of the blocking holes and the isolation holes. This design enables the box-type substation to maintain the best protection status under different weather conditions: on rainy days or in humid environments, the blocking holes and the isolation holes are misaligned, effectively preventing rainwater and moisture from invading the interior of the box through the heat dissipation vents; on sunny or dry days, the blocking holes and the isolation holes overlap, ensuring normal ventilation and heat dissipation of the heat dissipation vents. This intelligent adjustment mechanism not only improves the automation level of the box-type substation, but also significantly enhances its adaptability and durability, providing a solid guarantee for the stable operation of the power system.

[0024] Optionally, a hinge seat is fixed on the outer periphery of the support rod, a locking screw hole is opened on the hinge seat, and a locking through hole that can coincide with the locking screw hole is opened on the end of the traction rod; a locking bolt is provided on the outside of the box body, which passes through the locking through hole and is screwed into the locking screw hole.

[0025] By adopting the above technical solution, the design of the hinged seat on the support rod, the locking through hole at the end of the drawbar, and the locking screw hole, combined with the locking bolt, ensures that the connection between the drawbar and the support rod can be flexibly disassembled and re-articulated as needed, while remaining stable and prevented from falling off during operation. This design not only facilitates quick installation of the drawbar for cleaning the observation window, but also allows for easy removal after cleaning, restoring the box-type substation to its original state. Furthermore, the tightening action of the locking bolt ensures the stability and reliability of the drawbar during operation, preventing safety hazards caused by loosening or falling off.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A downward-facing protective cover is set on the outside of the heat dissipation port of the box, and an upward-facing drainage cover is set on the inside of the heat dissipation port, which effectively solves the rainwater protection problem faced by box-type substations in rainy coastal areas.

[0027] 2. A horizontal cover plate inside the enclosure slides along the inner wall of the enclosure via vertical rods at either end, flexibly sealing and opening the hood opening. When heavy rain falls, a driver drives the vertical rods and cover plate downward, quickly sealing the hood opening and effectively preventing rainwater from entering the enclosure through the heat dissipation vents. When the weather improves and the rain subsides, a reset element drives the cover plate and vertical rods upward, releasing the seal on the hood and restoring normal cooling function.
