Description

Technical Field

[0001] This application relates to the field of JP cabinet technology, and in particular to a JP cabinet for outdoor use. Background Technology

[0002] In power systems, outdoor JP (Power Switchgear) cabinets, as crucial electrical equipment, undertake key functions such as power distribution, control circuits, and protection devices. They are widely used in urban and rural power grid upgrades, residential communities, factories, and other outdoor locations. With the continuous development of the power industry, higher demands are placed on the performance and reliability of outdoor JP cabinets. Good moisture-proof and heat dissipation performance is essential for ensuring the normal operation of electrical components within the JP cabinet, extending equipment lifespan, and reducing the failure rate. Improper handling of moisture-proofing and heat dissipation can lead to damage to electrical components due to moisture, decreased insulation performance, short circuits, and other faults, seriously affecting the stability and security of power supply.

[0003] In related technologies, the following methods are commonly used to solve the problems of moisture prevention and heat dissipation. One method is to use a sealed cabinet, sealing the gaps in the cabinet with materials such as sealing strips to prevent humid air from entering the cabinet and thus achieving the purpose of moisture prevention. At the same time, a few ventilation openings are made in the cabinet and filters are installed to achieve a certain degree of heat dissipation through natural ventilation. Another method is to install a dehumidifier and a cooling fan inside the cabinet. The dehumidifier removes moisture from the cabinet through cooling or moisture absorption, while the cooling fan accelerates heat dissipation by forcing airflow. Some designs also coat the cabinet surface with a heat-insulating coating to reduce the transfer of external heat.

[0004] However, while sealed cabinets offer some moisture protection, their ventilation and heat dissipation are poor, easily leading to excessively high internal temperatures and affecting the performance and lifespan of electrical components. Installing dehumidifiers and cooling fans requires additional power, increasing energy consumption and equipment costs; furthermore, in humid environments, dehumidifiers and fans are susceptible to moisture damage. Applying heat-insulating coatings only reduces some heat transfer; they cannot effectively dissipate heat generated inside the cabinet, failing to fundamentally solve the heat dissipation problem. Furthermore, traditional methods struggle to automatically adjust moisture protection and heat dissipation based on changes in ambient humidity, failing to simultaneously meet the dual requirements of "sealed moisture protection" and "ventilation and heat dissipation," resulting in poor adaptability of outdoor JP cabinets under varying humidity conditions. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a JP cabinet for outdoor use.

[0006] An outdoor JP cabinet includes a cabinet body, and an adaptive moisture-proof valve is installed on the side wall of the cabinet body; the adaptive moisture-proof valve includes: The valve body is located on the side wall of the cabinet and has a through-hole to connect the inside and outside of the cabinet. The valve core assembly is movably housed within the valve body cavity for opening and closing the valve body cavity. A drive element, made of an ambient humidity-responsive material, is disposed within the valve body cavity and connected to the valve core assembly, for driving the valve core assembly to close the valve body cavity when the ambient humidity increases; and... The elastic reset element acts on the valve core assembly to drive the valve core assembly to open the valve body cavity when the ambient humidity decreases. The valve body is made of thermally conductive material, and its exposed surface has a heat dissipation structure.

[0007] By adopting the above technical solutions, an intelligent response infrastructure was established, enabling bidirectional functional self-adaptation. It automatically seals and protects in humid environments and automatically opens for heat dissipation in dry conditions. This solves the fundamental contradiction between traditional JP cabinets with open-hole heat dissipation and sealed moisture prevention, and also provides passive heat dissipation capabilities, allowing for continuous heat dissipation through heat conduction even when the valve is closed.

[0008] Optionally, the valve core assembly includes a valve core rod and a sealing head disposed at one end of the valve core rod; the valve body cavity is provided with a valve seat that mates with the sealing head; when the driving component drives the valve core rod to move, the sealing head engages or disengages from the valve seat.

[0009] By adopting the above technical solutions, the separate valve core rod and sealing head design facilitates processing and maintenance, improves sealing reliability, and ensures precise fit between the sealing head and valve seat. The valve core rod can effectively transmit the thrust of the driving component to the sealing head, forming a stable sealing pressure. The modular design allows the sealing head to be replaced individually, reducing maintenance costs. An intelligent response structure is established, which can automatically adjust moisture-proof and heat dissipation according to the ambient humidity. It automatically closes for protection in humid environments and automatically opens for heat dissipation in dry conditions, resolving the contradiction between traditional JP cabinets with open-hole heat dissipation and sealing for moisture protection. The valve body, made of thermally conductive material, combined with the external heat dissipation structure, can continue to dissipate heat through heat conduction even when the valve is closed.

[0010] Optionally, the sealing head is a conical head, and the valve seat is provided with a sealing surface that matches the sealing head, forming a conical sealing pair.

[0011] By adopting the above technical solutions, an intelligent response infrastructure was established, enabling bidirectional functional self-adaptation and providing passive heat dissipation capabilities; improving sealing reliability, optimizing force transmission paths, and enhancing system maintainability; enhancing sealing performance, providing self-alignment capabilities, and extending service life.

[0012] Optionally, the driving component is an annular moisture-absorbing expander, which is sleeved on the valve core assembly; after absorbing moisture, the moisture-absorbing expander expands radially and generates axial thrust, driving the valve core assembly to move and close the valve body cavity.

[0013] By adopting the above technical solutions, precise humidity response is achieved. The annular hygroscopic expansion body provides uniform axial thrust, ensuring timely and reliable valve closure. Space utilization is optimized, with the annular structure compactly fitted onto the valve core assembly, maximizing the use of the valve body's internal cavity space. Long-term stability is guaranteed, as the radial expansion of the hygroscopic expansion material is converted into axial thrust, avoiding interference with the valve core's movement.

[0014] Optionally, the heat dissipation structure is a heat dissipation fin integrally formed with the valve body.

[0015] By adopting the above technical solutions, a basic structure for intelligent response is established, enabling bidirectional functional self-adaptation, providing passive heat dissipation capabilities, maximizing heat dissipation efficiency, enhancing structural integrity, and reducing manufacturing costs.

[0016] Optionally, the valve body is attached to the cabinet sidewall via a quick-installation assembly, which includes: A magnetic sealing ring is fitted onto the valve body to magnetically attract the metal surface of the cabinet side wall during installation, thus achieving a preliminary seal. The rotating buckle, located on the valve body, is used to lock and tighten the sealing ring by rotating it at a certain angle to the mounting groove on the cabinet after the valve body is connected to the side wall of the cabinet.

[0017] By adopting the above technical solutions, rapid installation and maintenance are achieved. The magnetic sealing ring provides initial positioning and sealing, while the rotating buckle ensures reliable locking, significantly shortening the installation time. The installation is sealed, and the double sealing design guarantees the protection level at the connection between the valve body and the cabinet. On-site operation convenience is improved, and installation and disassembly can be completed without special tools, reducing the technical requirements for operators.

[0018] Optionally, a dust filter is provided at the air inlet end of the valve body cavity.

[0019] By adopting the above technical solution, a dust filter is installed at the air inlet end of the valve body cavity on the basis of the adaptive moisture-proof valve. This can filter particulate matter in the air when the valve is opened, keep the cabinet clean, reduce the impact of dust, insects, etc. on the valve core moving mechanism and moisture-absorbing expansion body, prevent dust accumulation on the heat dissipation fins from affecting heat dissipation efficiency, extend the service life of the valve, and maintain stable heat dissipation performance.

[0020] Optionally, the inner wall of the valve body is provided with a limiting boss to limit the maximum opening stroke of the valve core assembly.

[0021] By adopting the above technical solutions, a basic structure for intelligent response was established, enabling bidirectional functional self-adaptation, providing passive heat dissipation capabilities, while precisely controlling valve opening, protecting the drive mechanism, and ensuring optimized airflow channels.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining the valve body, valve core assembly, drive component and elastic reset component, a moisture-proof heat dissipation system that can automatically adjust according to the ambient humidity is constructed, realizing fully autonomous humidity response control without external energy, and solving the fundamental contradiction between the traditional JP cabinet's open heat dissipation and sealed moisture prevention. 2. The valve body, made of thermally conductive material, is combined with one-piece molded heat dissipation fins, which can continue to dissipate heat through heat conduction even when the valve is closed. The combination of conduction and convection heat dissipation forms a composite heat dissipation mechanism, which improves heat dissipation efficiency. 3. The design employs a multi-stage sealing and protection system, including a conical sealing head and valve seat forming a conical sealing pair, a magnetic sealing ring, and a rotating snap fastener, to ensure long-term stable operation in harsh outdoor environments.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0026] A JP cabinet for outdoor use, see reference Figure 1The system includes a cabinet 1, an adaptive moisture-proof valve mounted on the side wall of cabinet 1, and a heat dissipation structure within the adaptive moisture-proof valve, establishing a self-responsive core structure for moisture-proof and heat dissipation. The adaptive moisture-proof valve detects the humidity environment inside cabinet 1 and opens or closes cabinet 1 according to the humidity level. The heat dissipation structure lowers the temperature of cabinet 1 by reducing the surface temperature of the adaptive moisture-proof valve. The adaptive moisture-proof valve, in conjunction with the heat dissipation structure within it, achieves the dual function of "sealed protection in humid conditions and ventilation and heat dissipation in dry conditions," resolving the long-standing technical contradiction between "sealed moisture protection" and "ventilation and heat dissipation" in outdoor JP cabinets. Simultaneously, it improves the environmental adaptability of the JP cabinet, enabling it to automatically optimize its operating status under different humidity conditions.

[0027] Reference Figure 1 , Figure 2 , Figure 3 The adaptive moisture-proof valve includes a valve body 2, a valve core assembly 3 disposed within the valve body 2, and a drive assembly 4 for driving the valve core assembly 3 to work. The drive assembly 4 is used to drive the valve core assembly 3 to close the valve body 2 when the ambient humidity increases, thereby sealing the cabinet 1.

[0028] The valve body 2 is made of high thermal conductivity aluminum alloy. The surface of the cabinet 1 has a mounting groove 5, and the bottom of the mounting groove 5 has a mounting hole 6 for the valve body 2 to pass through. In addition, a fixing plate 7 is fixed to the outer surface of the inner part of the valve body 2 by screws, so that the fixing plate 7 is axially fitted on the outer surface of the valve body 2.

[0029] The fixing plate 7 includes a heat-conducting part 701 and a connecting part 702. The connecting part 702 is an annular structure that matches the outer surface of the valve body 2 and is sleeved on the outer surface of the valve body 2. The heat-conducting part 701 is integrally formed on the outer wall of the connecting part 702 away from the valve body 2. The heat-conducting part 701 can be a circular plate or a square plate, and a heat-conducting pad 8 is covered on its surface. This allows the heat-conducting part 701 to abut against the inner wall of the cabinet 1 through the heat-conducting pad 8, thereby allowing the heat inside the cabinet 1 to be transferred to the side wall of the cabinet 1 through the heat-conducting pad 8. The surface of the heat-conducting part 701 has multiple pre-set holes for connecting with the cabinet 1. Screws can pass through the heat-conducting pad 8 and the pre-set holes to be threaded into the cabinet 1, thereby fixing the heat-conducting part 701 of the fixing plate 7 to the cabinet 1.

[0030] The portion of the valve body 2 outside the cabinet 1 is detachably connected to the outer wall of the cabinet 1 via a quick-installation assembly 9. Simultaneously, multiple heat dissipation fins 10 are integrally formed on the portion of the valve body 2 outside the cabinet 1. Furthermore, a copper heat-conducting plate 11 is fixedly connected to the side of the heat dissipation fins 10 closest to the cabinet 1. The heat-conducting plate 11 is inserted into a corresponding slot on the surface of the cabinet 1 and passes through the slot to adhere to the heat-conducting pad 8 on the surface of the fixing plate 7. The fixing plate 7 is then connected and fixed to the heat-conducting plate 11 and the heat dissipation fins 10 with screws, thereby improving the stability of the valve body 2. Additionally, the heat dissipation fins 10 can be detachably connected to the surface of the valve body 2 with screws, and the heat-conducting plate 11 can be integrally formed onto the heat dissipation fins 10, thereby increasing the assembly speed of the valve body 2.

[0031] A fixing groove 12 is formed on the surface of the valve body 2. A magnetic sealing ring 901 is axially fitted on the surface of the valve body 2, and the sealing ring 901 abuts against the inner wall of the fixing groove 12. It is used to generate magnetic attraction with the metal surface of the side wall of the cabinet 1 when the valve body 2 is installed, thereby sealing the gap between the valve body 2 and the mounting hole 6. At the same time, a rotating buckle 902 is threadedly connected to the inner wall of the fixing groove 12, and the rotating buckle 902 is fitted on the outer surface of the valve body 2. The peripheral of the rotating buckle 902 is provided with a threaded structure, which is used to connect with the arc-shaped surface of the mounting groove 5. While initially fixing and locking the valve body 2 to the cabinet 1, it further presses the sealing ring 901.

[0032] The valve body 2 has an inner cavity that extends through itself, which is used to connect the inside of the cabinet 1 with the external environment. A dust filter 13 is fixedly connected to the inner wall of the air inlet end of the valve body 2 to prevent external impurities from entering the valve body 2 through the inner cavity.

[0033] The valve core assembly 3 is movably housed within the inner cavity of the valve body 2. A limiting boss 14 and a valve seat 15 are fixedly connected to the inner wall of the valve body 2, wherein the valve seat 15 cooperates with the limiting boss 14 to limit the travel of the valve core assembly 3. The valve core assembly 3 is slidably mounted between the valve seat 15 and the limiting boss 14, and the valve seat 15 cooperates with the valve core assembly 3 to open or close the inner cavity of the valve body 2.

[0034] The limiting boss 14 includes an integrally formed fixing part 1401 and a boss part 1402. The fixing part 1401 is sleeved on the outer surface of the boss part 1402 and is fixedly connected to the valve body 2 by screws. The boss part 1402 protrudes towards the side near the valve seat 15 and is hollow. Both the fixing part 1401 and the boss part 1402 have multiple through holes on their surfaces for gas exchange between the inside of the cabinet 1 and the outside.

[0035] The valve core assembly 3 includes a valve core rod 301 and a sealing head 302 fixedly connected to one end of the valve core rod 301. One end of the valve core rod 301 passes through a positioning hole opened in the center of the positioning plate boss 1402, and the positioning plate and the inner wall of the positioning block are rotatably connected by ball bearings 16 to reduce frictional loss between the valve core rod 301 and the positioning plate. The sealing head 302 is fixedly connected to the end of the valve core rod 301 facing the valve seat 15. The sealing head 302 is a conical head with a rubber gasket covering its surface. The valve seat 15 has a sealing surface that matches the sealing head 302, and the sealing head 302 and the sealing surface combine to form a conical sealing pair.

[0036] The drive assembly 4 includes a drive member 401 and an elastic reset member 402. The drive member 401 is an annular hygroscopic expansion body, specifically a synthetic rubber modified with a superabsorbent polymer. The drive member 401 is sleeved on the portion of the valve core rod 301 within the limiting boss 14. Simultaneously, a drive plate is fixedly connected to the surface of the portion of the valve core rod 301 within the limiting boss 14. The drive member 401 is located between the drive plate and the sidewall of the limiting boss 14 on the side away from the valve seat 15. After the drive member 401 absorbs moisture, the drive member 401, composed of the hygroscopic expansion body, expands radially and generates axial thrust, thereby pushing the drive plate towards the valve seat 15 to close the inner cavity.

[0037] The elastic reset member 402 is axially sleeved between the valve core rod 301 and the side wall of the drive plate and the limiting boss 14 near the valve seat 15. The elastic reset member 402 can be a spring and is coated with an anti-rust layer. After the drive member 401 dries, the elastic reset member 402 is used to push the drive plate to slide away from the valve seat 15 to open the inner cavity.

[0038] The cabinet 1 is also equipped with a drainage structure, which includes a water guide pipe 17 embedded in the side wall of the cabinet 1. One end of the water guide pipe 17 extends into the inner cavity of the valve body 2 and is connected to the bottom of the boss portion 1402 of the limiting boss 14. The other end of the water guide pipe 17 is fixedly connected to a drain check valve 18, and the outlet of the drain check valve 18 is located on the outer surface of the side wall of the cabinet 1. It is used to collect the residual water in the driving member 401 when the elastic reset member 402 squeezes the driving member 401 and causes the inner cavity to open, and discharge it through the drain check valve 18.

[0039] The implementation principle of this application embodiment is as follows: the outdoor JP cabinet dynamically responds to environmental changes through a highly integrated adaptive moisture-proof and heat dissipation system, and its working principle is based on the synergistic effect of mechanical balance and thermodynamic conduction.

[0040] When the ambient humidity increases, the annular hygroscopic expansion body made of superabsorbent polymer modified rubber absorbs moisture from the air, generates radial expansion, and converts it into axial thrust.

[0041] The thrust overcomes the elastic force of the elastic reset element 402, pushes the drive plate and valve core rod 301, and makes the conical sealing head 302 tightly pressed into the valve seat 15, forming a reliable conical sealing pair, completely blocking the exchange of air inside and outside the cabinet and preventing moisture intrusion.

[0042] At this time, the magnetic sealing ring 901 and the rotating buckle 902 ensure the static seal of the installation interface between the valve body 2 and the cabinet 1, achieving all-round high-level protection.

[0043] When the ambient humidity decreases, the moisture-absorbing expansion body loses water and shrinks, reducing the axial thrust it exerts. The elastic force of the elastic reset element 402 is then released, pushing the drive plate and valve core rod 301 to move in the opposite direction, causing the sealing head 302 to leave the valve seat 15, and the valve to open.

[0044] Hot air inside the cabinet is exhausted through the through-holes on the limiting boss 14, the open valve port, and the inner cavity, while cold air from the outside enters, creating natural convection that carries away the heat. Heat inside the cabinet is transferred to the fixing plate 7 via air convection and radiation, and then conducted to the side wall of the cabinet 1 via the thermal pad 8, dissipating from the entire surface of the cabinet 1 to the outside. Simultaneously, heat from the fixing plate 7 is conducted through the slot to the thermal plate 11, and then to the heat dissipation fins 10 integrated with the valve body 2, achieving efficient heat dissipation through the large surface area.

[0045] Both incoming and outgoing airflow are filtered through the dust filter 13 to keep the cabinet clean. When the valve is first opened after a long period of closure, the elastic reset element 402 forcefully compresses the moisture-absorbing expansion body. Any trace moisture that may be released is collected by the water guide pipe 17 at the bottom of the limiting boss 14 and discharged outside the cabinet through the drain check valve 18, eliminating any possibility of internal water accumulation. The ball bearing 16 design between the valve core rod 301 and the limiting boss 14 reduces frictional loss, and the rust-proof layer of the spring ensures its long-term elastic stability.

[0046] In summary, this embodiment integrates humidity sensing, power drive, sealing, ventilation, heat conduction and drainage functions through ingenious mechanical structure design, and realizes intelligent, efficient and reliable control of the internal environment of the JP cabinet in a purely physical way.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
