Description

Technical Field

[0001] This invention relates to the field of ring network box technology, and in particular to a ring network box with a condensation and dehumidification structure. Background Technology

[0002] A ring main unit (also known as a ring main cabinet) is an electrical device that houses a set of power transmission and distribution equipment in a metal or non-metal insulated cabinet or is assembled into a modular ring main power supply unit. However, ring main units are usually installed in outdoor open-air environments with harsh working conditions. In spring and autumn, there are large temperature differences between day and night, and large differences in temperature and humidity between the inside and outside of the cabinet. In addition, due to factors such as water accumulation in cable wells, small space inside the cabinet, and poor air circulation, the humidity inside the ring main unit is high and condensation may even occur. This can lead to a decrease in equipment insulation and electrical flashover, and in severe cases, it can cause safety accidents. Therefore, in order to prevent condensation inside the ring main unit, the existing technology usually adopts a condensation dehumidification method, which uses the cooling function of semiconductor electronic components to condense water vapor molecules in the air into water, and then discharges them outside the cabinet through a water pipe, thereby achieving the purpose of moisture prevention and dehumidification.

[0003] However, existing ring main units are usually seamless, enclosed, all-metal structures with strong sealing but limited internal convection space. When the dehumidifier needs maintenance, it usually needs to be disassembled first. Although existing technologies have removable dehumidification structures, this only solves the problem of ease of disassembly and assembly. When the dehumidifier is pulled out for maintenance, the drainage structure of the dehumidifier still needs to be disassembled, which is cumbersome and prone to leakage. In addition, in humid or low-temperature environments, the drainage structure is prone to sewage or moisture backflow, and the drainage pipe may freeze, causing dehumidification failure. At the same time, the heat dissipation system, drainage system and installation structure of existing ring main units are designed independently, lacking functional coupling and synergy. Summary of the Invention

[0004] The problems to be solved by this invention are: cumbersome disassembly and assembly of pipes during dehumidification equipment maintenance; easy backflow and icing of drainage structures; and lack of coordination between various functional structures.

[0005] To solve the above-mentioned technical problems, the present invention provides a ring network box with a condensation dehumidification structure, including a box body and a dehumidifier disposed in the upper part of the inner cavity of the box body. Linear guide rails are fixedly connected to both sides of the upper part of the inner wall of the box body. A heat dissipation plate is fixedly connected to the back of the inner cavity of the box body. A connecting groove is opened in the middle of the heat dissipation plate. A drain pipe is disposed in the inner cavity of the connecting groove. A water outlet pipe is fixedly connected to the output end of the dehumidifier. A detachable sealing docking structure is provided between the drain pipe and the water outlet pipe. The sealing assembly includes a first pair of connectors connected to the end of the outlet pipe, a second pair of connectors connected to the top of the drain pipe, a tapered plug connected to the end of the first pair of connectors away from the outlet pipe, and a tapered docking block connected to the end of the second pair of connectors away from the drain pipe.

[0006] Preferably, both the first and second connecting pipes are equipped with self-sealing valves, the conical plug is interference-fitted to the inner cavity of the conical mating block, a sealing ring is fixedly connected to the side of the second connecting pipe near the conical plug, and one end of the conical mating block is connected to the inner cavity of the sealing ring.

[0007] Preferably, the top ends of the two linear guide rails are jointly mounted with a mounting bracket, the dehumidifier is fixedly mounted on the mounting bracket, and the mounting bracket is movably mounted in the inner cavity of the box via the linear guide rails.

[0008] Preferably, the inner wall of the connecting groove is arc-shaped, the drain pipe contacts the heat dissipation plate through the inner wall of the connecting groove, and the hot end of the back of the dehumidifier contacts the heat dissipation plate.

[0009] Preferably, the end of the drain pipe away from the second connecting pipe passes through the box and is connected to an anti-backflow pipe for discharging condensate outside the box. One end of the anti-backflow pipe is connected to an external drain pipe. A floating block is provided at the bottom of the inner cavity of the anti-backflow pipe. The floating block is movably connected to the connection between the anti-backflow pipe and the external drain pipe. A limiting groove is provided on the lower part of the inner wall of the anti-backflow pipe to limit the floating position of the floating block.

[0010] Preferably, a guide groove for guiding the flow direction of the drying gas is provided on one side of the top of the inner cavity of the box, and a return groove for the circulating return of the drying gas is provided on the other side of the top of the inner cavity of the box. The guide groove is inclined towards the return groove, and the inner wall of the return groove is arc-shaped.

[0011] Preferably, the surface of the drain pipe is fitted with a first fixing ring for reinforcement, and the second connecting pipe is fitted with a second fixing ring for reinforcement. The first fixing ring is fixedly connected to the heat dissipation plate, and the second fixing ring is fixedly connected to the inner wall of the box.

[0012] Preferably, two cooling fans for heat dissipation are installed on the back of the heat sink, the air outlets of the cooling fans penetrate through the back of the housing, and the inner cavity of the housing is provided with a device rack for installing electronic components.

[0013] The technical effects and advantages of this invention are as follows: This invention utilizes a heat dissipation plate to absorb the heat generated during the operation of the dehumidifier and the ring network box. The drain pipe is tightly attached to the heat dissipation plate through a connecting groove on the arc-shaped inner wall, effectively increasing the contact area between the drain pipe and the heat dissipation plate. The drain pipe runs along the direction of the connecting groove, effectively extending the contact length with the heat dissipation plate. The waste heat absorbed by the heat dissipation plate heats the drain pipe, keeping the temperature inside the pipe above the freezing point. This effectively prevents condensate from freezing and clogging the pipe in low-temperature winter environments, and reuses the waste heat. No additional deheating equipment is needed to solve the problem of drain pipe freezing, effectively avoiding resource waste. At the same time, during the condensate discharge process, the floating block increases buoyancy and floats upward, automatically opening the drain outlet and allowing the condensate to be discharged from the external drain pipe. After drainage stops, the floating block falls and automatically closes the drain outlet. This automatic drainage structure effectively prevents water accumulation or rainwater backflow from the external environment and also prevents the intrusion of humid air.

[0014] This invention achieves pipe sealing during dehumidifier assembly and disassembly by incorporating a sealing docking assembly. When the dehumidifier requires maintenance or repair, it is pulled from the working position to the maintenance position via a linear guide rail, separating the first and second pairs of connecting pipes. When pushed back, the first and second pairs of connecting pipes automatically dock. A self-sealing valve is also included, automatically closing when the first and second pairs of connecting pipes separate and automatically opening when they are inserted, preventing residual water in the pipes from flowing into the housing when the first and second pairs of connecting pipes separate. When the first and second pairs of connecting pipes dock, the conical plug and the conical docking block form an interference fit. Even if there is a slight deviation in the initial positioning, the conical surface will guide the component to automatically slide into the correct position during insertion, achieving precise docking. This avoids the need to disassemble the drain pipe during the assembly and disassembly process of existing dehumidifier installation methods, where the disassembled drain pipe cannot be precisely docked and may become entangled within the device, affecting the normal operation of other electronic components.

[0015] This invention utilizes a guide channel and a return channel to guide the flow of dry gas, forming a circulating return airway. The dry gas, dehumidified by the dehumidifier, is ejected upwards from the outlet into the guide channel, flows along the inclined direction of the guide channel into the inner cavity of the return channel, and then flows downwards along the curvature of the inner wall of the return channel. Utilizing the principle of rising humid air, the design incorporates air intake from both sides and exhaust from the top. The dry air impacts the top of the chamber and then flows downwards, forming an internal circulation system. This design facilitates effective airflow within the chamber, ensuring dehumidification and preventing the introduction of high-humidity external air in humid environments from actually increasing the humidity inside the chamber. The circulating dry air also continuously removes moisture from the surfaces of electrical equipment, fundamentally preventing condensation and maintaining the insulation performance of the equipment and a stable environmental control within the chamber.

[0023] This invention provides a ring network box with a condensation and dehumidification structure, such as... Figure 1 - Figure 6As shown, the device includes a housing 1 and a dehumidifier 2 located in the upper part of the inner cavity of the housing 1. Linear guide rails 3 are fixedly connected to both sides of the upper part of the inner wall of the housing 1. A heat dissipation plate 4 is fixedly connected to the back of the inner cavity of the housing 1. A connecting groove 5 is opened in the middle of the heat dissipation plate 4. A drain pipe 6 is installed in the inner cavity of the connecting groove 5. A water outlet pipe 7 is fixedly connected to the output end of the dehumidifier 2. A detachable sealing docking assembly 8 is provided between the drain pipe 6 and the water outlet pipe 7. The condensing dehumidifier 2 mainly consists of a semiconductor cooling chip, a cold-end condenser with a condensation cavity, a hot-end radiator with a heat dissipation cavity, and a cooling fan. It is based on the Peltier effect, which causes the cold end of the semiconductor cooling chip to cool down and condense air after being energized. Water vapor in the air and the hot end generate heat simultaneously and are discharged through the heat dissipation structure. The water vapor contained therein reaches a saturated state and condenses into liquid water, thereby separating and discharging the moisture in the air to achieve continuous dehumidification. The condensate produced is discharged through the water outlet pipe 7. Meanwhile, the linear guide rail 3 is mainly composed of a track, a slider and a drive device. The drive device drives the slider to move linearly on the track. The linear guide rail 3 allows the dehumidifier 2 to be installed and moved within the cavity of the housing 1, enabling uninterrupted maintenance and quick disassembly and assembly of the condensation dehumidification structure in the ring network box. Since the existing technologies of the linear guide rail 3 and the dehumidifier 2 are relatively mature, they will not be described in detail here.

[0024] Furthermore, such as Figure 1 - Figure 3 As shown, the sealing assembly 8 includes a first pair of connecting pipes 81 connected to the end of the outlet pipe 7, and a second pair of connecting pipes 82 connected to the top of the drain pipe 6. A tapered plug 83 is connected to the end of the first pair of connecting pipes 81 furthest from the outlet pipe 7, and a tapered connecting block 84 is connected to the end of the second pair of connecting pipes 82 furthest from the drain pipe 6. When the dehumidifier 2 needs maintenance or repair, it is pulled from the working position to the maintenance position via the linear guide rail 3, separating the first pair of connecting pipes 81 and the second pair of connecting pipes 82, thus enabling operation without shutting down the ring main unit. After completing the maintenance or repair of dehumidifier 2, dehumidifier 2 is pushed back to its original position. When dehumidifier 2 is pushed back, the first pair of connecting pipes 81 connects with the second pair of connecting pipes 82. The linear guide rail 3 and the automatic sealing docking assembly 8 realize the linear insertion and removal action of dehumidifier 2. This prevents the existing installation method of dehumidifier from requiring the removal of the drainage structure during disassembly and reassembly. Furthermore, the disassembled drainage structure cannot be accurately reconnected when reinstalled, making the operation very cumbersome. It may also cause entanglement in the device and affect the normal use of other electronic components.

[0025] Furthermore, such as Figure 3As shown, both the first pair of connecting pipes 81 and the second pair of connecting pipes 82 are equipped with self-sealing valves 85. The conical plug 83 is interference-fitted with the inner cavity of the conical mating block 84. A sealing ring 86 is fixedly connected to the surface of the second pair of connecting pipes 82 near the conical plug 83. One end of the conical mating block 84 is connected to the inner cavity of the sealing ring 86. The self-sealing valve 85 automatically closes when the first pair of connecting pipes 81 and the second pair of connecting pipes 82 are separated and automatically opens when they are inserted, preventing residual water in the pipes from flowing into the housing 1 when the first pair of connecting pipes 81 and the second pair of connecting pipes 82 are separated. At the same time, the conical design... The designed connection structure ensures that even if there is a slight initial positioning deviation between the first pair of connecting pipes 81 and the second pair of connecting pipes 82, the conical surface will guide the components to automatically slide into the correct position during insertion, achieving precise docking. At the same time, the conical mating surfaces of the conical plug 83 and the conical docking block 84 will form an interference fit after being inserted to the bottom, ensuring efficient sealing between the water outlet pipe 7 and the drain pipe 6, preventing water leakage at the water outlet connection when the dehumidifier 2 is pushed back into its original position after maintenance. In addition, the sealing ring 86 is added to ensure the tightness of the connection between the conical plug 83 and the conical docking block 84.

[0026] Furthermore, such as Figure 1 As shown, a mounting bracket 9 is installed at the top of both linear guide rails 3. The dehumidifier 2 is fixedly installed on the mounting bracket 9, and the mounting bracket 9 is movably installed in the inner cavity of the housing 1 via the linear guide rails 3. The mounting bracket 9 is connected by a slider in the linear guide rails 3. Maintenance personnel only need to pull out the entire dehumidifier 2 along the linear guide rails 3, just like pulling out a drawer. When the dehumidifier 2 is pulled out, the conical plug 83 and the conical mating block 84 automatically separate, and the self-sealing valves 85 on both sides close simultaneously to prevent water leakage. After the dehumidifier 2 is fully pulled out, it will be exposed to the outside of the housing 1 without any obstruction, providing a very spacious operating space for inspection, cleaning and replacement of parts. After maintenance, the dehumidifier 2 can be pushed back. When the dehumidifier 2 is pushed back, the conical plug 83 and the conical mating block 84 automatically align and insert, and the self-sealing valves 85 on both sides open simultaneously, restoring the sealing passage. The use of the linear guide rails 3 to make the mounting bracket 9 flush along its direction of movement effectively improves the accuracy of the mating of the conical plug 83 and the conical mating block 84.

[0027] Furthermore, such as Figure 2 and Figure 5As shown, the inner wall of the connecting groove 5 is arc-shaped. The drain pipe 6 contacts the heat sink 4 through the inner wall of the connecting groove 5. The hot end of the back of the dehumidifier 2 contacts the heat sink 4. The arc-shaped inner wall of the connecting groove 5 increases the contact area, allowing the drain pipe 6 to fit tightly against the heat sink 4. At the same time, the drain pipe 6 runs along the inner wall of the connecting groove 5, effectively extending the contact length with the heat sink 4, allowing the flowing water sufficient time to absorb heat. Meanwhile, when the semiconductor cooler in the dehumidifier 2 is working, the residual heat generated at the hot end is absorbed by the heat sink 4, effectively improving the heat dissipation effect of the dehumidifier 2. Furthermore, since the heat sink 4 continuously absorbs heat during the operation of the ring network box, the heat on the heat sink 4 is used to preheat the drain pipe 6, keeping the temperature inside the pipe above the freezing point, thereby effectively preventing condensate from freezing and clogging the pipe in low-temperature winter conditions.

[0028] Furthermore, such as Figure 2 and Figure 4 As shown, the end of the drain pipe 6 away from the second connecting pipe 82 passes through the housing 1 and is connected to a backflow prevention pipe 10 for draining condensate outside the housing 1. One end of the backflow prevention pipe 10 is connected to an external drain pipe 11. A floating block 12 is provided at the bottom of the inner cavity of the backflow prevention pipe 10. The floating block 12 is movably connected to the connection between the backflow prevention pipe 10 and the external drain pipe 11. A limiting groove 13 is provided at the lower part of the inner wall of the backflow prevention pipe 10 to limit the floating position of the floating block 12. After the condensate flows into the inner cavity of the backflow prevention pipe 10, the water level rises, and the buoyancy of the floating block 12 increases. When the buoyancy is greater than its own weight, the floating block... 12 floats up and automatically opens the drain outlet; when there is no condensate, the water level drops, the buoyancy disappears, and the floating block 12 falls down by its own weight, automatically closing the drain outlet; at the same time, the floating block 12 floats up and down within the range of the limiting groove 13, and the limiting groove 13 ensures that the floating block 12 can move vertically and stably up and down, accurately landing on the drain outlet. The automatic drainage structure effectively avoids the situation where sewage backflow occurs when water or rainwater accumulates in the external environment and is higher than the outlet of the external drain pipe 11. At the same time, it can also prevent humid air in the external environment from entering the box 1 through the external drain pipe 11 and affecting the use of the ring network box.

[0029] Furthermore, such as Figure 5As shown, a guide channel 14 for guiding the flow of dry gas is provided on one side of the top of the inner cavity of the housing 1, and a return channel 15 for the recirculation of dry gas is provided on the other side of the top of the inner cavity of the housing 1. The guide channel 14 is inclined towards the return channel 15, and the inner wall of the return channel 15 is arc-shaped. The air inlet of the dehumidifier 2 is located at both ends, and the air outlet is located at the top, with the position of the air outlet corresponding to the position of the guide channel 14. The humid air in the housing enters the dehumidifier 2 through the air inlets on both sides, and the dry gas dehumidified by the dehumidifier 2 is sprayed upward from the air outlet to the guide channel 14. The air flows along the inclined direction of the guide channel 14 into the inner cavity of the return channel 15, and then flows downward along the curvature of the inner wall of the return channel 15. Utilizing the principle of rising humid and hot air, air is drawn in from both sides and discharged from the top. The dry air impacts the top of the box and flows downward, forming an internal circulation design. This design helps to create effective airflow inside the box, ensuring dehumidification and preventing the introduction of high external air humidity in a humid environment from increasing the humidity inside the box. The dry air circulating inside the box can also continuously remove moisture from the surface of electrical equipment, fundamentally preventing condensation and maintaining the insulation performance of the equipment and stable environmental control inside the box.

[0030] Furthermore, such as Figure 3 and Figure 5 As shown, a first fixing ring 16 for reinforcement is fitted on the surface of the drain pipe 6, and a second fixing ring 87 for reinforcement is fitted on the second connecting pipe 82. The first fixing ring 16 is fixedly connected to the heat dissipation plate 4, and the second fixing ring 87 is fixedly connected to the inner wall of the box 1. The stability of the second connecting pipe 82 and the drain pipe 6 is increased by the first fixing ring 16 and the second fixing ring 87.

[0031] Furthermore, such as Figure 1 and Figure 6 As shown, two cooling fans 17 for heat dissipation are installed on the back of the heat sink 4. The air outlet of the cooling fan 17 passes through the back of the box 1. The inner cavity of the box 1 is provided with a device rack 18 for installing electronic components. The heat absorbed on the heat sink 4 is discharged from the box 1 by the cooling fans 17, so as to achieve the heat dissipation effect of the ring network box.

[0032] The working principle of this invention is as follows: First, the dehumidifier 2 is fixed on the mounting bracket 9, which is then connected to it via a slider in the linear guide rail 3, achieving a sliding connection of the dehumidifier 2 within the housing 1. During the operation of the ring network box, the dehumidifier 2 is activated, and the humid air inside the box enters the dehumidifier 2 through the air inlets on both sides. The dry air after being dehumidified by the dehumidifier 2 is sprayed upward from the air outlet to the guide channel 14, flows along the inclined direction of the guide channel 14 to the inner cavity of the return channel 15, and then flows downward along the arc of the inner wall of the return channel 15, forming an internal circulation within the housing 1. This also continuously removes moisture from the surface of electrical equipment. The dehumidifier 2 removes... The condensate generated during the wetting process flows from the outlet pipe 7 to the drain pipe 6, and then flows along the drain pipe 6 to the anti-backflow pipe 10. After the condensate flows into the inner cavity of the anti-backflow pipe 10, the water level rises, and the floating block 12 experiences increased buoyancy. When the buoyancy exceeds its own weight, the floating block 12 floats up, automatically opening the drain outlet, and the condensate is discharged from the outer drain pipe 11 outside the housing 1. When there is no condensate, the water level drops, the buoyancy disappears, and the floating block 12 falls under its own weight, automatically closing the drain outlet. Since the ring network box and dehumidifier 2 generate heat during operation, this heat is absorbed by the heat dissipation plate 4, and the drain pipe 6... The heat sink 4 is connected to its inner wall via a connecting groove 5 on the heat sink 4. The heat from the heat sink 4 preheats the drain pipe 6, keeping the temperature inside the pipe above freezing. This effectively prevents condensate from freezing and clogging the pipe in low-temperature winter conditions. When the dehumidifier 2 needs maintenance or repair, it is pulled from the working position to the maintenance position via the linear guide rail 3. The first pair of connecting pipes 81 and the second pair of connecting pipes 82 separate, and the conical plug 83 and the conical mating block 84 also automatically separate. The self-sealing valves 85 on both sides close simultaneously to prevent leakage, allowing maintenance or repair of the dehumidifier 2 to be completed without shutting down the ring network box. After the operation is completed, the dehumidifier 2 is pushed back to its original position. When the dehumidifier 2 is pushed back, the first pair of connecting pipes 81 connects with the second pair of connecting pipes 82. At the same time, the conical plug 83 and the conical docking block 84 automatically align and insert, and the self-sealing valves 85 on both sides open simultaneously, restoring the sealing passage. The linear guide rail 3 and the automatic sealing docking assembly 8 realize the linear insertion and removal action of the dehumidifier 2, forming a complete closed loop of coordinated work among the three major functional modules: the waste heat reuse structure of the drain pipe 6 to the heat dissipation plate 4, the antifreeze and anti-backflow structure of the drain pipe 6, and the installation structure of the dehumidifier 2 and the on / off structure of the pipeline in the automatic sealing docking assembly 8.
