Description

Technical Field

[0001] The present invention relates to the technical field of outdoor ring main units, and specifically to an anti-condensation device for an outdoor ring main unit. Background Art

[0002] The anti-condensation device for an outdoor ring main unit is mainly used to avoid the occurrence of condensation inside the cabinet due to temperature and humidity changes. This kind of condensation may damage electrical equipment or cause equipment failures; However, the existing anti-condensation devices for outdoor ring main units have the following problems during the anti-condensation process: Problem 1: The existing anti-condensation devices prevent condensation by heating, dehumidifying, or continuously powering on. At night, the environmental temperature is relatively low, and the temperature difference between the cabinet body and the outside of the cabinet is relatively large. Condensation is likely to occur inside the cabinet body. By setting heating elements to prevent condensation, the use of heating elements will increase the additional output power of the cabinet body, resulting in an increase in operating costs. At the same time, it will cause the inside of the cabinet body to overheat, which will also lead to a relatively high temperature at the core part of the cabinet body, and a large temperature difference will be formed with the surrounding parts of the cabinet body; Based on Problem 1, Problem 2 is proposed: The existing cabinet bodies do not have corresponding ventilation structures set according to the outdoor environment. During the day, in different regions, the outdoor temperature is either relatively high or relatively low. When the outdoor temperature is relatively high, ventilation and heat dissipation are required for the cabinet body to prevent the cabinet body temperature from being too high. At the same time, corresponding adjustment components are set to adjust the ventilation system to prevent the influence on equipment operation when the outdoor temperature is too low. In view of the above problems, the inventor proposes an anti-condensation device for an outdoor ring main unit to solve the above problems. Summary of the Invention

[0003] In order to solve the condensation problem caused by a large temperature difference, corresponding ventilation and diversion structures need to be set; the purpose of the present invention is to provide an anti-condensation device for an outdoor ring main unit.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: It includes a cabinet body, a cabinet door is installed on the outer wall of the cabinet body, and a temperature and humidity sensor and a door switch are installed on the cabinet door; A first housing is arranged inside the cabinet body, a gap is arranged between the first housing and the inner wall of the cabinet body, a circulation port is arranged on the outer wall of the first housing, the circulation port leads to the gap between the first housing and the cabinet body, and a ventilation component is installed at one end of the first housing close to the circulation port; Through holes are arranged on the outer wall of the first housing, a second housing is arranged inside the first housing, a plurality of fixing plates are installed on the inner wall of the second housing, and heat-conducting aluminum plates are installed on the fixing plates, and the heat-conducting aluminum plates extend to the top and bottom of the second housing; The fixing plates are used to carry equipment, and the heat-conducting aluminum plates are used to conduct the heat of the equipment; The gap and the top port of the second housing extend to the top of the cabinet body. An installation plate is installed on the top of the cabinet body, and a diversion component is installed on the installation plate. The diversion component extends to the bottom of the cabinet body through the gap; By adopting the above technical solution, the temperature and humidity sensor is installed on the cabinet door, which can monitor the temperature and humidity of the internal or surrounding environment of the cabinet body in real time. At night, when the temperature difference between the inside and outside of the cabinet body is detected to be large, the control switch door and the ventilation component are operated to control the introduction of external gas into the cabinet body. The gas passes through the circulation port and the through hole to reach the gap. Driven by the ventilation component continuously, the gas flows upward, is preheated at the bottom of the second housing, and the cold air flow forms normal temperature gas. Subsequently, the normal temperature gas passes through the top of the second housing, mixes with the hot air flow of the heat-conducting aluminum plate, and drives the hot air flow to flow upward, flowing to the diversion component. The heat is diffused to the inside of the cabinet body through the diversion component and then flows out to the outside of the cabinet body, thereby reducing the temperature difference and playing a role in preventing condensation.

[0005] Preferably, the switch door includes a door panel and a cylinder. The cylinder is installed on the cabinet door, the door panel is installed on the output shaft of the cylinder, a port is opened on the cabinet door, and the door panel is slidably connected to the cabinet door and closes the port; By adopting the above technical solution, at night, when the temperature difference between the inside and outside of the cabinet body is detected to be large, the control switch door is operated, and the output shaft of the cylinder drives the door panel to move, opening the port of the cabinet door, so as to facilitate gas circulation.

[0006] Preferably, the ventilation component includes a double-shaft motor and fan blades. The double-shaft motor is installed on the outer wall of the first housing, the fan blades are installed on the output shaft of the double-shaft motor, and the fan blades are arranged inside the circulation port; By adopting the above technical solution, the output shaft of the double-shaft motor drives two fan blades to rotate simultaneously. The rotation directions of the two fan blades are opposite. One of the circulation ports is for air intake, and the other circulation port is for air exhaust, thereby increasing the air flow circulation inside the cabinet body.

[0007] Preferably, an inlet is opened on the top of the first housing, and a plug door is inserted into the inlet; By adopting the above technical solution, the plug door is installed or disassembled to open the port of the first housing, so as to install the network device.

[0008] Preferably, a plurality of air flow grooves are opened on the outer wall of the second housing, and the air flow grooves are inside the gap; By adopting the above technical solution, when the external air flow enters the gap, it circulates along the air flow grooves. During the flow process, due to the large temperature difference between the inside and outside of the cabinet body, the external air flow exchanges heat with the heat on the outer wall of the second housing.

[0009] Preferably, the heat-conducting aluminum plate at the top of the second shell has a plurality of air flow holes on its outer wall, and the air flow holes extend to the top of the heat-conducting aluminum plate; By adopting the above technical solution, the air flow passes through the heat-conducting aluminum plate to conduct the heat of the device, and then takes the heat away upward through the air flow holes, thereby preventing the internal heat of the second shell from being too high.

[0010] Preferably, a guide plate is installed on the inner wall of the gap, and the guide plate extends to the port of the through hole; By adopting the above technical solution, the guide plate guides the incoming airflow and the outgoing airflow.

[0011] Preferably, a plurality of inclined plates are fixedly connected to the outer wall of the second shell and the inner wall of the first shell, and the two groups of inclined plates are staggered and inclined with respect to each other; By adopting the above technical solution, the flow distance of the airflow is increased, thereby increasing the time for heat exchange between two different heats.

[0012] Preferably, the flow guide component comprises a foam plate, the foam plate is provided with a plurality of air holes, and the flow guide component is mounted on the mounting plate and is located at the top ports of the two second shells; By adopting the above technical solution, the air holes on the foam board can reserve a certain amount of heat in the airflow. When subsequent gas enters, the heat inside the foam board will continue to be pushed, and part of the heat will rise to the top inner wall of the cabinet, exchanging heat with the top of the cabinet to prevent excessive heat.

[0013] Preferably, the bottom of the foam board is connected to a plurality of plastic rods, the plastic rods are located at the inner corners of the cabinet, and a plurality of circular holes are opened on the outer walls of the plastic rods; By adopting the above technical solution, the heat in the foam board is supplemented to the periphery of the cabinet through the plastic rod, thereby preventing the center and edge of the cabinet from having a high temperature and preventing condensation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a flow guide component, and the air flow passes through the heat-conducting aluminum plate to conduct the heat of the equipment, and then takes the heat upward through the air flow holes to avoid excessive heat inside the second shell and the equipment. The air holes on the foam plate reserve a certain amount of heat in the air flow. When subsequent gas enters, the heat inside the foam plate is continued to be pushed, and part of the heat rises to the top inner wall of the cabinet, and heat exchanges with the top of the cabinet to prevent excessive heat. The heat in the foam plate is supplemented to the surrounding of the cabinet through the plastic rod to prevent the center and edge of the cabinet from being too hot, thereby preventing condensation.

[0015] 2. Through the arrangement of the ventilation component, when the temperature difference between the inside and outside of the cabinet is detected to be large at night, the control switch door operates, thereby controlling the adjustment of the air flow rate entering and leaving the inside of the cabinet to adapt to different working environments. The output shaft of the double-shaft motor drives two fan blades to rotate simultaneously, and the rotation directions of the two fan blades are opposite. One of the circulation ports is for air intake, and the other circulation port is for air exhaust, thereby increasing the internal air flow circulation of the cabinet. While exchanging heat between the external air flow and the internal air flow of the cabinet, the gas circulation is maintained, enhancing the air flow inside the cabinet, helping to evenly distribute the temperature, and at the same time reducing the temperature difference between the inside and outside of the cabinet, thereby further preventing condensation.

[0016] 3. Through the arrangement of the inclined plate, the two groups of inclined plates are arranged in an intersecting and inclined manner, increasing the travel of the air flow, thereby increasing the time for heat exchange between two different heats, and thus increasing the time for heat exchange of the core part of the cabinet. While dissipating heat from the core part, the waste heat is supplemented to the periphery of the cabinet through the foam board and the plastic rod, preventing a large temperature difference between the central part and the edge of the cabinet, and further preventing condensation.

The rotation directions of the two fan blades 602 are opposite. One of the circulation ports 501 is used for air intake, and the other circulation port 501 is used for air exhaust, so as to increase the air flow circulation inside the cabinet 1.

[0039] A plurality of air flow grooves 1001 are provided on the outer wall of the second housing 10, and the air flow grooves 1001 are located inside the gap; By adopting the above technical solution, when the external air flow enters the interior of the gap, it flows along the air flow grooves 1001. During the flowing process, due to the large temperature difference between the inside and outside of the cabinet body 1, the external air flow exchanges heat with the heat on the outer wall of the second housing 10.

[0040] A heat conduction aluminum plate 11 is provided at the top of the second housing 10, and a plurality of air holes 1101 are provided on its outer wall, and the air holes 1101 extend to the top of the heat conduction aluminum plate 11; By adopting the above technical solution, the air flow conducts the heat of the equipment through the heat conduction aluminum plate 11, and then takes the heat away upward through the air holes 1101, so as to prevent the heat inside the second housing 10 from being too high.

[0041] A flow guide plate 9 is installed on the inner wall of the gap, and the flow guide plate 9 extends to the port of the through hole 502; By adopting the above technical solution, the flow guide plate 9 guides the incoming air flow and the outgoing air flow.

[0042] A plurality of inclined plates 12 are fixedly connected to the outer wall of the second housing 10 and the inner wall of the first housing 5, and the two groups of inclined plates 12 are inclined alternately; By adopting the above technical solution, the travel of the air flow is increased, so as to increase the time of heat exchange between two different heats.

[0043] The flow guide assembly 7 includes a foam board 701, a plurality of air holes are provided on the foam board 701, and the flow guide assembly 7 is installed on the mounting plate 13 and is located at the top ports of the two second housings 10; By adopting the above technical solution, the air holes on the foam board 701 store a certain amount of heat in the air flow. When the subsequent gas enters, the heat inside the foam board 701 is continuously pushed, and part of the heat rises to the top inner wall of the cabinet body 1 and exchanges heat with the top of the cabinet body 1 to prevent the heat from being too high.

[0044] A plurality of plastic rods 702 are communicated with the bottom of the foam board 701, the plastic rods 702 are located at the inner corners of the cabinet body 1, and a plurality of round holes are provided on the outer wall of the plastic rods 702; By adopting the above technical solution, the heat in the foam board 701 is supplemented to the periphery of the cabinet body 1 through the plastic rod 702, preventing the temperature difference between the central part and the edge of the cabinet body 1 from being large and preventing condensation.

[0045] Working principle: The temperature and humidity sensor 3 is installed on the cabinet door 2 and can monitor the temperature and humidity of the internal or surrounding environment of the cabinet body 1 in real time. At night, when the temperature difference between the inside and outside of the cabinet body 1 is detected to be large, the control switch door 4 and the ventilation component 6 are controlled to operate, so as to control the introduction of external gas into the cabinet body 1. The gas reaches the gap through the circulation port 501 and the through hole 502. Driven by the ventilation component 6 continuously, the gas flows upward from bottom to top inside the gap, is preheated at the bottom of the second housing 10, and the cold air flow forms normal temperature gas, reducing the temperature difference from the internal core temperature. Subsequently, the normal temperature gas passes through the top of the second housing 10, mixes with the hot air flow of the heat conduction aluminum plate 11, and drives the hot air flow to flow upward, flowing to the diversion component 7. The heat diffuses to the periphery inside the cabinet body 1 through the diversion component 7, compensating the surrounding temperature, thereby reducing the temperature difference between the core part and the surrounding part of the cabinet body 1, and then flowing out to the outside of the cabinet body 1. At the same time, the internal air flow of the cabinet body 1 is maintained, so that the internal temperature is evenly distributed, and thus the function of preventing condensation is achieved; The output shaft of the biaxial motor 601 drives two fan blades 602 to rotate simultaneously. The rotation directions of the two fan blades 602 are opposite. One of the circulation ports 501 is used for air intake, and the other circulation port 501 is used for air exhaust, thereby increasing the internal air flow circulation of the cabinet body 1, helping to evenly distribute the temperature, and preventing the local temperature from being too high; When the external air flow enters the gap, it circulates along the air flow groove 1001. During the flowing process, due to the large temperature difference between the inside and outside of the cabinet body 1, after the external air flow enters, heat exchange occurs between the external air flow and the heat on the outer wall of the second housing 10. The air flow circulation conducts the heat of the equipment through the heat conduction aluminum plate 11, and then takes the heat upward through the air flow hole 1101 to avoid the excessive heat inside the second housing 10. The two groups of inclined plates 12 are arranged in a staggered and inclined manner to increase the travel of the air flow, thereby increasing the time for heat exchange between the two different heats. When the external air flow enters, it cools down the second housing 10 and the heat conduction aluminum plate 11. When part of the air flow flows out from the other direction through the circulation port 501, the heat carried by the air flow is compensated along the outer wall of the second housing 10, keeping the temperature of the second housing 10, the heat conduction aluminum plate 11 and the equipment neither too high nor too low, preventing the high temperature from affecting the operation of the equipment, and leaving a certain temperature to keep the equipment running; During the process of the air flow entering and discharging from the cabinet body 1, the guide plate 9 guides the incoming air flow and the discharged air flow, and the air flow flows out or flows in through the through hole 502; The pores in the foam board 701 store a certain amount of heat in the air flow. When subsequent gas enters, the heat inside the foam board 701 is further pushed. Part of the heat rises to the top inner wall of the cabinet 1 and exchanges heat with the top of the cabinet 1 to prevent the temperature from being too high. The heat in the foam board 701 is supplemented to the periphery of the cabinet 1 through the plastic rods 702, preventing a large temperature difference between the central part and the edge of the cabinet 1 and preventing condensation.
