Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, and in particular to a ring main unit with dehumidification and anti-condensation functions. Background Technology

[0002] A ring main unit is a key electrical device used in medium-voltage power distribution networks (typically 6kV~24kV voltage levels). Its core function is to construct a ring power supply network to achieve flexible power distribution and fault isolation.

[0003] Chinese patent application CN202011215327.2 discloses an anti-condensation ring main unit. Although this application can activate the cooling fan to blow air out of the cabinet when condensation is detected, and simultaneously activate the heating device and drive device to make the cooling fan swing back and forth, the condensation generated in the cabinet is dried by the hot air blown by the cooling fan, thereby eliminating condensation, when this application is put into use, the temperature on the outside is difficult to keep constant due to the different geographical locations of the ring main unit. When the ring main unit is placed in a metal box exposed to direct sunlight outdoors, the temperature inside the cabinet will rise rapidly, resulting in a lower external ambient temperature. This creates a situation where the internal temperature is high and the external temperature is low, which easily leads to condensation. At the same time, if it is placed outdoors in winter, the external temperature of the ring main unit is low, while the internal components of the ring main unit continue to work, resulting in a higher internal temperature. The heat dissipation method alone cannot effectively prevent the formation of condensation. The high temperature and moisture inside the cabinet condenses into water on the cold outer shell, causing condensation, which can lead to a decrease in insulation or flashover.

[0004] Therefore, how to provide a ring main unit with dehumidification and anti-condensation functions is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide a ring main unit with dehumidification and anti-condensation functions. This invention can effectively adaptively and dynamically adjust the internal components of the ring main unit in response to environmental changes, in order to cope with different situations.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a ring network cabinet with dehumidification and anti-condensation function, including a ring network cabinet body and a rotary drive assembly, wherein a partition frame is fixedly connected to the bottom rear side of the ring network cabinet body, and a ball bearing fan is provided at the top of the partition frame.

[0007] The rotation drive assembly includes: The drive motor is fixedly connected to the back of the partition frame. The drive motor has an output shaft that passes through the inner wall of the back of the ring main unit and extends into the interior of the ring main unit. A rotating cylinder is fixedly connected to the inner wall of the back of the rotating cylinder. An electric telescopic rod is fixedly connected to the front of the rotating cylinder. The front of the rotating base is rotatably connected to the back of the partition frame. A positioning frame is fixedly connected to the rear end of the outer side of the rotating base. The electric telescopic rod has a telescopic end. A sliding guide plate is fixedly connected to the telescopic end of the electric telescopic rod. Drive frames are fixedly connected to the outer side of the sliding guide plate in a circumferential manner at equal intervals. When the drive motor is working, it can drive the rotating cylinder and the rotating base to rotate on the back of the partition frame. When the electric telescopic rod is working, it can drive the sliding guide plate and drive frames to move.

[0008] Furthermore, it also includes a flipping assembly, which consists of a flipping connecting arm plate, a second drive frame, a rotating flipping frame, a guide positioning rod, a moving slider, and an elastic telescopic belt.

[0009] The flipping connecting arm plate is hinged to the inner middle of the drive frame one, and the drive frame two is hinged to the side of the flipping connecting arm plate away from the drive frame one.

When the drive frame one moves, it can drive the rotating flipping frame on the drive frame two to move through the flipping connecting arm plate, and the movable slider can slide guided by the guide positioning rod.

[0010] Furthermore, it also includes an adaptive adjustment component, which consists of a telescopic sleeve, a connecting rotating frame, a rotating connecting block, a bidirectional telescopic arc rod, a fixed plate, a hinge frame, and an elastic heat-absorbing plate.

[0011] The telescopic sleeve is fixedly connected to the left and right sides of the movable slider. The telescopic sleeve has a telescopic end. The connecting rotating frame is fixedly connected to the telescopic end of the telescopic sleeve. The rotating connecting block is rotatably connected to the middle of the connecting rotating frame. The bidirectional telescopic arc rod is fixedly connected to the side of the rotating connecting block away from the telescopic sleeve. The fixed plate is fixedly connected to the middle of the bottom of the bidirectional telescopic arc rod. The hinge frame is rotatably connected to the fixed plate through a torsion spring in the middle. The elastic heat-absorbing plate is fixedly connected to the side of the hinge frame away from the fixed plate. When the telescopic sleeve extends or retracts, it enables the rotating connecting block to rotate within the connecting rotating frame.

[0012] Furthermore, the top of the partition frame is provided with ventilation slots that connect the upper and lower sides, the front of the partition frame is provided with airflow slots that connect the front and back, and the bottom of the back of the ring main unit is provided with an air outlet slot. By setting the ventilation slots and airflow slots, the heat inside the ring main unit can be directed to the back of the partition frame, and by setting the air outlet slot, the air at the partition frame can be sent out of the ring main unit through the air outlet slot.

[0013] Furthermore, a rectangular groove is provided on the outer side of the rotating cylinder, and a sliding groove is provided inside the sliding guide plate. The sliding guide plate is slidably connected to the inner wall of the rotating cylinder through the sliding groove. During the movement of the sliding guide plate, the drive frame can move synchronously within the rectangular groove on the outer side of the rotating cylinder.

[0014] Furthermore, the rotating flip-plate frame is rotatably connected to the center of the positioning frame on the side near the rotating base. When the rotating flip-plate frame is subjected to the force transmitted by the second drive frame, it can rotate around the center of the positioning frame in an adaptive direction.

[0015] Furthermore, the elastic telescopic belt is fixedly connected to the inner wall of the rotating flip-plate frame on the side away from the moving slider, which can fix the elastic telescopic belt and provide elastic support for the moving slider after the elastic telescopic belt is fixed.

[0016] Furthermore, the front of the elastic heat-absorbing plate is in contact with the back of the partition frame, and the elastic heat-absorbing plate can absorb the heat from the front of the partition frame when it is in contact with the partition frame.

[0017] Furthermore, a temperature monitor is installed inside the ring main unit to monitor the temperature inside the ring main unit in real time. Multiple ball bearings are installed on the side of the elastic heat-absorbing plate that contacts the back of the partition frame. When the motor drives the rotating cylinder to rotate, the elastic heat-absorbing plate can roll normally on the back of the partition frame. The electric telescopic rod is a battery-driven electric push rod.

[0018] Furthermore, both ends of the bidirectional telescopic arc rod are provided with telescopic sleeves, connecting rotating frames, and rotating connecting blocks. The number of drive frame one, flip connecting arm plate, drive frame two, rotating flip plate frame, guide positioning rod, movable slider, elastic telescopic belt, telescopic sleeve, connecting rotating frame, rotating connecting block, bidirectional telescopic arc rod, fixed plate, hinge frame, and elastic heat absorption plate are all four. The four drive frame one, flip connecting arm plate, drive frame two, rotating flip plate frame, guide positioning rod, movable slider, elastic telescopic belt, telescopic sleeve, connecting rotating frame, rotating connecting block, bidirectional telescopic arc rod, fixed plate, hinge frame, and elastic heat absorption plate are all arranged in a ring on the outside of the rotating base. Adjacent movable sliders are connected by telescopic sleeves, connecting rotating frames, rotating connecting blocks, and bidirectional telescopic arc rods. When the distance between the movable sliders changes, the telescopic sleeve and bidirectional telescopic arc rod can dynamically extend and retract synchronously.

[0019] The beneficial effects of this invention are: 1. In this invention, when the internal temperature of the ring main unit is continuously high, the centrifugal force generated by the rotation of the drive motor can automatically expand the spacing of the elastic heat absorption plates, significantly increasing the heat dissipation area and air circulation efficiency, thereby achieving rapid and powerful heat dissipation. 2. In this invention, the drive motor controls the continuous rotation of the elastic heat-absorbing plate so that it periodically contacts the high-temperature areas of different regions, avoiding local overheating. At the same time, the centrifugal force can automatically remove dust and lint from the plate surface, maintain heat dissipation efficiency, and reduce maintenance requirements. 3. In this invention, when the external temperature of the ring main unit is high and the internal temperature is low, the electric telescopic rod can be controlled to gather the elastic heat absorption plate and turn off the ball bearing fan, thereby reducing heat loss and air flow. The heat stored in the gathered elastic heat absorption plate can be released slowly, delaying the temperature drop inside the unit and playing an active heat preservation role, preventing the problem of condensation at low temperatures. 4. In this invention, when the elastic heat-absorbing plate itself overheats and threatens the life of the fan, the position and angle of the elastic heat-absorbing plate can be actively adjusted so that it is removed from the heat source and directly exposed to the airflow of the ball fan, thereby achieving rapid and efficient cooling and protecting the heat-absorbing plate from high temperature damage. 5. In this invention, when the outside temperature is low and the inside temperature is high, the elastic heat dissipation plate is driven to unfold by an electric telescopic rod, so that the elastic heat absorption plate is in close contact with the partition frame to absorb the heat of the electronic components. With the help of the ball bearing fan for forced convection, the heat is discharged from the air outlet slot on the back side, which significantly reduces the temperature difference between the inside and outside of the cabinet and fundamentally avoids the formation of condensation.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] Example 1 refer to Figure 1-9 The present invention provides a technical solution: a ring network cabinet with dehumidification and anti-condensation function, including a ring network cabinet body 1, and a rotary drive assembly 4. A partition frame 2 is fixedly connected to the bottom rear side of the ring network cabinet body 1, and a ball bearing fan 3 is provided at the top of the partition frame 2.

[0024] The rotary drive component 4 includes: A drive motor 401 is fixedly connected to the back of the partition frame 2. The drive motor 401 has an output shaft that passes through the inner wall of the back of the ring network cabinet 1 and extends into the interior of the ring network cabinet 1. A rotating cylinder 402 is fixedly connected to the inner wall of the back of the rotating cylinder 402. An electric telescopic rod 403 is fixedly connected to the front of the rotating cylinder 402. A rotating base 404 is fixedly connected to the front of the rotating base 404 and rotatably connected to the back of the partition frame 2. A positioning frame 405 is fixedly connected to the rear end of the outer side of the rotating base 404. The electric telescopic rod 403 has a telescopic end. A sliding guide plate 406 is fixedly connected to the telescopic end of the electric telescopic rod 403. A drive frame 407 is fixedly connected to the outer side of the sliding guide plate 406 in a circumferential manner at equal intervals. When the drive motor 401 is working, it can drive the rotating cylinder 402 and the rotating base 404 to rotate on the back of the partition frame 2. When the electric telescopic rod 403 is working, it can drive the sliding guide plate 406 and the drive frame 407 to move.

[0025] The top of the partition frame 2 has ventilation slots that connect the upper and lower sides, and the front of the partition frame 2 has air flow slots that connect the front and back. The bottom of the back of the ring main unit 1 has an air outlet slot. By setting the ventilation slots and air flow slots, the heat inside the ring main unit 1 can be introduced to the back of the partition frame 2. By setting the air outlet slots, the air at the partition frame 2 can be sent out from the ring main unit 1 through the air outlet slots.

[0026] A rectangular groove is provided on the outer side of the rotating cylinder 402, and a sliding groove is provided in the inner side of the sliding guide plate 406. The sliding guide plate 406 is slidably connected to the inner wall of the rotating cylinder 402 through the sliding groove. During the movement of the sliding guide plate 406, the drive frame 407 can move synchronously in the rectangular groove on the outer side of the rotating cylinder 402.

[0027] When the ring main unit cabinet 1 is at room temperature, air continuously enters the cabinet from the outside, making the electronic components inside susceptible to moisture and reducing their lifespan. To address this, the ball bearing fan 3 inside the cabinet operates. When the ball bearing fan 3 is running, it draws air downwards through the ventilation slots at the top of the partition frame 2 and sends it out through the air outlet slots at the back of the cabinet. This accelerates airflow within the cabinet, maintaining a balanced humidity level and effectively preventing damage to the electronic components caused by moisture. Dehumidification is achieved without the need for heating, as airflow blocks the conditions for dew point temperature formation.

[0028] In practical applications, this design significantly improves the operational stability of the ring main unit (RN) cabinet 1. By optimizing the airflow path, it not only effectively reduces the risk of internal moisture accumulation but also reduces energy consumption, offering advantages over traditional heating and dehumidification methods. Furthermore, the structure considers adaptability to different environmental conditions, maintaining good working conditions in both hot and humid summers and cold and dry winters. To further enhance the effect, a temperature monitor is installed inside the equipment to collect temperature and humidity data in real time and dynamically adjust the airflow rate according to environmental changes, ensuring that the cabinet is always in an ideal operating environment. This design cleverly combines physical principles with modern technology, providing a strong guarantee for the long-term reliable operation of the RN.

[0029] Example 2 See Figure 9-10 Based on Embodiment 1, the present invention provides a technical solution that further includes a flipping assembly 5, which consists of a flipping connecting arm plate 501, a second drive frame 502, a rotating flipping frame 503, a guide positioning rod 504, a movable slider 505, and an elastic telescopic belt 506.

[0030] The flip-up connecting arm plate 501 is hinged to the middle of the drive frame 1 407. The drive frame 2 502 is hinged to the side of the flip-up connecting arm plate 501 away from the drive frame 1 407. The rotating flip plate frame 503 is fixedly connected to the front of the drive frame 2 502. The guide positioning rod 504 is fixedly connected to the middle of the rotating flip plate frame 503. The movable slider 505 is slidably connected to the outside of the guide positioning rod 504. The elastic telescopic belt 506 is fixedly connected to the side of the movable slider 505 near the rotating base 404. When the drive frame 1 407 moves, it can drive the rotating flip plate frame 503 on the drive frame 2 502 to move through the flip-up connecting arm plate 501. The movable slider 505 can slide guided on the outside of the guide positioning rod 504.

[0031] The rotating flip-plate frame 503 is rotatably connected to the middle of the positioning frame 405 on the side near the rotating base 404. When the rotating flip-plate frame 503 is subjected to the force transmitted by the drive frame 502, it can rotate around the middle of the positioning frame 405 in an adaptive direction.

[0032] The elastic telescopic belt 506 is fixedly connected to the inner wall of the rotating flip frame 503 on the side away from the movable slider 505, which can fix the elastic telescopic belt 506. At the same time, after the elastic telescopic belt 506 is fixed, it can provide elastic support for the movable slider 505.

[0033] Example 3 See Figure 11-13Based on Embodiment 2, the present invention provides a technical solution that further includes an adaptive adjustment component 6, which is composed of a telescopic sleeve 601, a connecting rotating frame 602, a rotating connecting block 603, a bidirectional telescopic arc rod 604, a fixing plate 605, a hinge frame 606, and an elastic heat-absorbing plate 607.

[0034] The telescopic sleeve 601 is fixedly connected to the left and right sides of the movable slider 505. The telescopic sleeve 601 has a telescopic end. The connecting rotating frame 602 is fixedly connected to the telescopic end of the telescopic sleeve 601. The rotating connecting block 603 is rotatably connected to the middle of the connecting rotating frame 602. The bidirectional telescopic arc rod 604 is fixedly connected to the side of the rotating connecting block 603 away from the telescopic sleeve 601. The fixing plate 605 is fixedly connected to the middle of the bottom of the bidirectional telescopic arc rod 604. The hinge frame 606 is rotatably connected to the fixing plate 605 through the torsion spring in the middle. The elastic heat-absorbing plate 607 is fixedly connected to the side of the hinge frame 606 away from the fixing plate 605. When the telescopic sleeve 601 is telescopic, the rotating connecting block 603 can rotate inside the connecting rotating frame 602.

[0035] The front of the elastic heat-absorbing plate 607 is in contact with the back of the partition frame 2. When the elastic heat-absorbing plate 607 is in contact with the partition frame 2, it can absorb the heat from the front of the partition frame 2.

[0036] The ring main unit cabinet 1 is equipped with a temperature monitor for real-time monitoring of the temperature inside the ring main unit cabinet 1. The elastic heat absorption plate 607 is provided with multiple ball bearings on the side that contacts the back of the partition frame 2. When the drive motor 401 drives the rotating cylinder 402 to rotate, the elastic heat absorption plate 607 can roll normally on the back of the partition frame 2. The electric telescopic rod 403 is a battery-driven electric push rod.

[0037] The bidirectional telescopic arc rod 604 is equipped with telescopic sleeves 601, connecting rotating frames 602, and rotating connecting blocks 603 at both ends. It also includes four drive frames 407, four flipping connecting arm plates 501, four drive frames 502, four rotating flip plate frames 503, four guide positioning rods 504, four moving sliders 505, four elastic telescopic belts 506, four telescopic sleeves 601, four connecting rotating frames 602, four rotating connecting blocks 603, four bidirectional telescopic arc rods 604, four fixed plates 605, four hinge frames 606, and four elastic heat-absorbing plates 607. The guide positioning rod 504, movable slider 505, elastic telescopic belt 506, telescopic sleeve 601, connecting rotating frame 602, rotating connecting block 603, bidirectional telescopic arc rod 604, fixing plate 605, hinge frame 606 and elastic heat absorption plate 607 are all distributed in a ring on the outside of the rotating base 404, and adjacent movable sliders 505 are connected by telescopic sleeve 601, connecting rotating frame 602, rotating connecting block 603 and bidirectional telescopic arc rod 604. When the distance between the movable sliders 505 changes, the telescopic sleeve 601 and bidirectional telescopic arc rod 604 can extend and retract synchronously.

[0038] When the ring main unit cabinet 1 is in a situation where the external temperature is low and the internal temperature is high, such as in winter when the external ambient temperature is low and the ring main unit cabinet 1 is in normal operation, condensation is likely to form on the outer shell of the ring main unit cabinet 1. At this time, it is necessary to quickly dissipate heat from the inside of the ring main unit cabinet 1. This is achieved by controlling the electric telescopic rod 403 to operate. When the electric telescopic rod 403 operates, it can drive the sliding guide plate 406 and the drive frame 407 to move synchronously, allowing the sliding guide plate 406 and the drive frame 407 to slide on the outer wall of the rotating cylinder 402. At this time, the drive frame 407, through the central flipping connecting arm plate 501, presses against the drive frame 502, causing the rotating flipping frame 503 on the other side of the drive frame 502 to be stressed, thus enabling... The rotating flip-plate frame 503 rotates relative to the positioning frame 405 at the connection point, so that the rotating flip-plate frame 503 and the drive frame 502 are perpendicular to each other. At this time, during the rotation, the rotating flip-plate frame 503 can make the elastic heat-absorbing plate 607 gradually contact the back of the partition frame 2, so that the elastic heat-absorbing plate 607 can absorb the heat generated by the electronic components on the front of the partition frame 2. With the help of the ball fan 3 set in the top of the partition frame 2, the heat absorbed by the elastic heat-absorbing plate 607 can be dissipated. Then, the heat is sent out through the air outlet duct set in the back of the ring network cabinet 1. When the external temperature is low and the internal temperature is high during use, the device can dissipate heat inside and avoid condensation caused by large temperature difference.

[0039] When the internal temperature of the ring main unit cabinet 1 continuously rises, requiring rapid heat dissipation, the drive motor 401 is activated. When the drive motor 401 is activated, it drives the rotating cylinder 402 to rotate. As the rotating cylinder 402 rotates, it rotates synchronously with the rotating base 404. The rotation of the rotating base 404 generates centrifugal force on the rotating flip-plate frame 503. Under the action of centrifugal force, the moving slider 505 slides on the guide positioning rod 504 within the rotating flip-plate frame 503, allowing the elastic telescopic band 506 on the moving slider 505 to stretch. Simultaneously, as the moving slider 505 moves outward on the guide positioning rod 504, the distance between the moving sliders 505 of adjacent rotating flip-plate frames 503 increases, enabling the telescopic sleeve 601 to adaptively stretch. This causes the connecting rotating frame 602 to move away from the rotating flip-plate frame 503, and the bidirectional telescopic arc rod 604 stretches synchronously, allowing it to move away from the rotating base 404. When the telescopic arc rod 604 moves, it can drive the elastic heat-absorbing plate 607 to move outward at the air flow groove on the back of the partition frame 2 via the bottom fixing plate 605. This increases the spacing between the four elastic heat-absorbing plates 607, allowing them to absorb the heat generated inside the ring main unit 1 evenly. At this time, the ball bearing fan 3 works, effectively dissipating heat from the elastic heat-absorbing plates 607. Meanwhile, the increased spacing between the elastic heat-absorbing plates 607 also helps to improve the smoothness of airflow, allowing heat to be quickly discharged from the inside of the ring main unit 1. The continuous rotation of the rotating cylinder 402 further optimizes the entire heat dissipation process, allowing the elastic heat-absorbing plates 607 to continuously move in contact with the air flow groove on the back of the partition frame 2. Compared to the static heat absorption of the elastic heat-absorbing plates 607, the rotation places the elastic heat-absorbing plates 607 in different areas on the back of the partition frame 2, allowing them to be periodically exposed to the high-temperature airflow, avoiding local overheating. At the same time, the centrifugal force generated by the rotation can shake off dust and lint adhering to the plate surface, maintaining surface cleanliness.

[0040] When the ring main unit cabinet 1 is in a condition where the external temperature is high and the internal temperature is low, it is necessary to insulate the interior to prevent condensation. The drive motor 401 is turned off, allowing the elastic telescopic belt 506 to regain its elasticity and pull the movable slider 505 along the guide positioning rod 504 towards the side closer to the rotating base 404. During the movement of the movable slider 505, the distance between the movable sliders 505 of two adjacent rotating flip-plate frames 503 shortens. At this time, the telescopic sleeve 601 dynamically and adaptively retracts, allowing the connecting rotating frame 602 to move towards the rotating flip-plate frame 503. Simultaneously, the rotating connecting block 603 rotates within the connecting rotating frame 602, and the bidirectional telescopic arc rod 604 adaptively and synchronously retracts. The elastic heat-absorbing plate 607 on the bidirectional telescopic arc rod 604 can move towards the rotating base 404. Since there are four of each type of elastic heat-absorbing plate 607, they can quickly converge on the outside of the rotating base 404. When the four elastic heat-absorbing plates 607 converge, they can concentrate the heat absorption. At the same time, the convergence of the elastic heat-absorbing plates 607 can partially block the airflow groove on the front of the partition frame 2, reducing the rate of temperature loss. At the same time, the ball bearing fan 3 is turned off, reducing the airflow inside the ring main unit 1. When the equipment temporarily stops heating or the heat output drops suddenly, the heat stored in the elastic heat-absorbing plate 607 can be slowly released, slowing down the rate of temperature drop inside the cabinet and effectively maintaining the temperature.

[0041] When the elastic heat-absorbing plate 607 continuously absorbs heat, resulting in a consistently high temperature, the lifespan of the ball bearing fan 3 is prone to overheating and reduction. At this time, the electric telescopic rod 403 inside the rotating cylinder 402 is activated, causing the electric telescopic rod 403 to pull the sliding guide plate 406. This causes the drive frame 407 on the sliding guide plate 406 to pull the flipping connecting arm plate 501, which in turn causes the drive frame 502 on the other side of the flipping connecting arm plate 501 to be stressed. Simultaneously, when the drive frame 502 is stressed, it causes the rotating flipping frame 503 to rotate in the middle of the positioning frame 405, causing the rotating flipping frame 503 to rotate towards the side closer to the rotating cylinder 402. The fixed plate 605 rotates within the hinge frame 606 via a torsion spring. After the elastic heat-absorbing plate 607 separates from the partition frame 2, the heat-absorbing side of the elastic heat-absorbing plate 607 can face away from the rotating cylinder 402. The drive motor 401 is slowly controlled to work, so that while the drive motor 401 drives the rotating cylinder 402 to rotate, the heat-absorbing side of the elastic heat-absorbing plate 607 can move to below the ball fan 3, so that the airflow delivered by the ball fan 3 can be directly blown onto the surface of the elastic heat-absorbing plate 607, thereby accelerating the heat dissipation rate of the elastic heat-absorbing plate 607 and preventing the elastic heat-absorbing plate 607 from overheating and causing damage.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
