Description

Technical Field

[0001] This utility model relates to the field of ring network box technology, specifically a primary and secondary integrated ring network box. Background Technology

[0002] The integrated primary and secondary ring main unit is a significant technological innovation in the power distribution field in recent years. It deeply integrates the primary and secondary equipment that were previously separate in traditional power distribution systems, forming a highly integrated intelligent power distribution solution. This type of equipment is becoming a new option for building green and smart grids, playing a crucial role in improving power supply reliability, security, and operation and maintenance efficiency.

[0003] During the period from late autumn to early winter (late October to early December), the large temperature difference between day and night causes moisture in the air to condense into water droplets on the inner wall of the low-temperature enclosure, making it the period of most severe condensation. When these water droplets fall onto the ring main unit housing the primary and secondary fusion equipment, they can cause corrosion and pose a risk of short circuits in the equipment's power system. Existing equipment typically uses electrical control devices to activate anti-condensation devices, which consumes electricity and is costly. Therefore, we propose a new primary and secondary fusion ring main unit. Utility Model Content

[0004] The purpose of this utility model is to provide a primary and secondary integrated ring network box to solve the problems mentioned in the background art.

[0006] Preferably, the top two sides of the cover plate are fixedly connected to connectors, and the connectors are slidably connected to sliding columns. One end of the sliding column is fixedly connected to the inner wall of one side of the box, and the other end of the sliding column is fixedly connected to a limiting piece for limiting the position of the connector.

[0007] Preferably, air inlet slots are respectively provided on the bottom of the opposite side of the box, and multiple air inlet slots are arranged in a linear array along the height direction of the box to form an air inlet.

[0008] Preferably, the air inlet and outlet slots are used to connect the housing to the outside and dissipate heat through natural air cooling.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By placing an airtight cylinder with an internal air pressure lower than that of room temperature inside the enclosure, the gas inside the airtight cylinder expands as the temperature rises during summer or when the equipment generates high temperatures inside the enclosure, causing the cover plate and sealing ring to separate. This allows the enclosure to circulate air through the air outlet and inlet slots, cooling the interior of the enclosure. When the ambient temperature drops in autumn and winter, the internal temperature of the enclosure also decreases, preventing the gas in the airtight cylinder from expanding. Under negative pressure, the cover plate adheres to the sealing ring, thus insulating the interior of the enclosure and preventing condensation that could lead to corrosion and short circuits. This structure requires no power supply, reducing energy consumption. Furthermore, it is simple in structure and inexpensive to manufacture.

[0012] By using the combination of an airtight cylinder, a sealing piston, a sealing ring, a cover plate, and a push-pull rod, when the internal temperature of the chamber is higher than the threshold, the cover plate and the sealing ring separate. When the ambient temperature is lower, the gas inside the airtight cylinder contracts, causing the cover plate and the sealing ring to close, thereby achieving automatic control of heat dissipation and heat preservation. The structure is simple and easy to maintain. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution: such as Figures 1-4The illustrated primary and secondary fusion ring network box includes a box body 1. Adjustment components are respectively installed on the inner walls of opposite sides of the box body 1. Each adjustment component includes an air outlet slot 2 formed at the top of one side of the box body 1. Multiple air outlet slots 2 are arranged in a linear array along the height direction of the box body 1 to form air outlets. A sealing ring 4 is fixedly connected to the inner wall of one side of the box body 1, and the sealing ring 4 surrounds the outer edge of the air outlet. A cover plate 5 for sealing is abutted against the other side of the sealing ring 4. A fixing cover 6 is fixedly connected to the inner wall of one side of the box body 1. An airtight cylinder 7 is fixedly sleeved inside the fixing cover 6. A sealing piston 8 is slidably sleeved on the inner wall of the airtight cylinder 7 for moving with the thermal expansion and contraction of the gas. The other end of the sealing piston 8 is fixedly connected to a push-pull rod 9, and the other end of the push-pull rod 9 is fixedly connected to one side of the cover plate 5. In the high temperature environment of summer, the air temperature in the cavity between the sealing piston 8 and the airtight cylinder 7 away from the push-pull rod 9 increases with the operation of the primary and secondary fusion equipment of the box 1, causing the air in the cavity to expand, thereby pushing the push-pull rod 9 to move laterally from inside the airtight cylinder 7 to the outside, so that the cover plate 5 fixed to it is no longer in contact with the sealing ring 4, thus forming a gap between the cover plate 5 and the sealing ring 4, allowing hot air to be discharged through the air outlet slot 2, and external air to enter the box 1 through the air inlet slot 13 at the bottom, so that the air circulates naturally in the box. The primary and secondary fusion equipment in body 1 is air-cooled. In autumn and winter, when the ambient temperature is low, the cooling requirements of the primary and secondary fusion equipment can be met by natural heat exchange between the metal body 1 and the outside environment. Due to the low ambient temperature, the gas inside the airtight cylinder 7 is not easily heated and expands, creating a negative pressure in the airtight cylinder 7. This pressure, in turn, pulls the push rod 9 through the sealing piston 8, causing the cover plate 5 to abut against the sealing ring 4. Under the heat released during the operation of the primary and secondary fusion equipment, the temperature inside body 1 is maintained within a certain range. This prevents water droplets from condensing on the inner wall of body 1 when it comes into contact with moisture in the air, thus avoiding water droplets dripping onto the surface. In the secondary fusion equipment, corrosion and short circuits occur. Under normal temperature conditions, the air pressure inside the airtight cylinder 7 is lower than the standard atmospheric pressure, forming a negative pressure. This causes the sealing piston 8 to pull the cover plate 5 to adhere to the sealing ring 4. When the heat from the operation of the primary and secondary fusion equipment heats the air inside the chamber 1, the air inside the airtight cylinder 7 is heated. At this time, the gas expands, causing the sealing piston 8 to move towards the push rod 9, separating the cover plate 5 from the sealing ring 4. The heated air rises and is discharged through the air outlet slot 2. The air inlet slot 13 replenishes the external air for circulating air cooling. When the internal temperature of the chamber 1 gradually recovers, the cover plate 5 and the sealing ring 4 adhere to each other again to form a seal.

[0017] like Figures 1-3As shown, connectors 10 are fixedly connected to both sides of the top of the cover plate 5. A sliding column 11 is slidably connected inside the connector 10, and one end of the sliding column 11 is fixedly connected to the inner wall of one side of the housing 1. The other end of the sliding column 11 is fixedly connected to a limiting piece 12 for limiting the connector 10. By placing an airtight cylinder 7 with an internal air pressure lower than the normal temperature air pressure inside the housing 1, in summer or when the inside of the housing 1 generates high temperature due to equipment operation, the gas inside the airtight cylinder 7 expands with the temperature rise, causing the cover plate 5 and the sealing ring 4 to... Separately, the housing 1 forms a natural air-cooled circulation through the air outlet slot 2 and the air inlet slot 13 to cool the inside of the housing 1. When the ambient temperature is low in autumn and winter, the internal temperature of the housing 1 also decreases, preventing the gas in the airtight cylinder 7 from expanding. Under the action of negative pressure, the cover plate 5 is pressed against the sealing ring 4, thereby insulating the inside of the housing 1 to avoid condensation, corrosion, and short circuits. Moreover, this structure does not require power supply, thus reducing energy consumption. At the same time, the structure is simple and the manufacturing cost is low.

[0018] Through the cooperation of the airtight cylinder 7, sealing piston 8, sealing ring 4, cover plate 5 and push-pull rod 9, when the internal temperature of the box 1 is higher than the threshold, the cover plate 5 and sealing ring 4 are separated. When the ambient temperature is low, the gas in the airtight cylinder 7 contracts, causing the cover plate 5 and sealing ring 4 to close, thus keeping the inside of the box 1 warm. This achieves automatic control of heat dissipation and heat preservation, and the structure is simple and easy to maintain.

[0019] like Figures 1-3 As shown, air inlet slots 13 are respectively opened on the bottom of the opposite side of the box 1, and multiple air inlet slots 13 are arranged in a linear array along the height direction of the box 1 to form an air inlet.

[0020] like Figures 1-3 As shown, the air inlet slot 13 and the air outlet slot 2 are used to connect the housing 1 to the outside and dissipate heat through natural air cooling. A guide shroud 3 is fixedly connected to the opposite side of the housing 1, and the guide shroud 3 is located at the top edge of each air outlet slot 2 and air inlet slot 13.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a hinge 16 is fixedly connected to one side of the box body 1, and an opening and closing door 14 is hinged to the box body 1 via the hinge 16. A sealing strip 15 for providing a seal to the opening and closing door 14 is fixedly connected to one side of the door frame of the box body 1.

[0022] like Figure 2 and Figure 3 As shown, a ring network cabinet 17 for accommodating primary and secondary fusion equipment is fixedly connected to the bottom inner wall of the housing 1, and grooves 18 distributed in a ring array around the central axis of the fixed cover 6 are opened on the side surface of the fixed cover 6.

[0023] Working Principle: In the high-temperature environment of summer, the air temperature in the cavity between the sealing piston 8 and the airtight cylinder 7, away from the push-pull rod 9, rises with the operation of the primary and secondary fusion equipment in the housing 1. This causes the air in the cavity to expand, pushing the push-pull rod 9 from inside the airtight cylinder 7 to the outside. This causes the cover plate 5, which is fixed to it, to no longer adhere to the sealing ring 4, thus creating a gap between the cover plate 5 and the sealing ring 4. This allows hot air to be discharged through the air outlet slot 2, while external air enters the housing 1 through the air inlet slot 13 at the bottom, allowing the air to circulate naturally and air-cool the primary and secondary fusion equipment in the housing 1. In autumn and winter, when the ambient temperature is low, the cooling requirements of the primary and secondary fusion equipment can be met by natural heat exchange between the metal housing 1 and the outside environment. Due to the low ambient temperature, the gas inside the airtight cylinder 7 is not easily heated and expands, creating a negative pressure in the airtight cylinder 7. This negative pressure causes the sealing piston 8 to pull the push-pull rod 9, causing the cover plate 5 to move laterally from inside the airtight cylinder 7 to the outside. 5 abuts against the sealing ring 4, and under the heat released during the operation of the primary and secondary fusion equipment, keeps the temperature inside the box 1 within a certain range, so that when the inner wall of the box 1 comes into contact with moisture in the air, it is not easy for water droplets to condense into water droplets, thus avoiding water droplets from dripping onto the primary and secondary fusion equipment, causing corrosion and short circuits; under normal temperature conditions, the air pressure inside the airtight cylinder 7 is lower than the standard atmospheric pressure, forming a negative pressure, which causes the sealing piston 8 to pull the cover plate 5 to adhere to the sealing ring 4. When the heat from the operation of the primary and secondary fusion equipment heats the air inside the box 1, the air inside the airtight cylinder 7 is heated, and the gas expands, which causes the sealing piston 8 to move towards the push rod 9, causing the cover plate 5 to separate from the sealing ring 4. The heated air rises and is discharged through the air outlet slot 2, and the air inlet slot 13 replenishes the external air for circulating air cooling. When the internal temperature of the box 1 gradually recovers, the cover plate 5 and the sealing ring 4 adhere to each other again to form a seal.
