Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ring main unit, in particular to a primary and secondary fusion complete ring main unit. BACKGROUND

[0002] The ring main unit is a group of power transmission and distribution electrical equipment installed in a metal or non-metal insulated cabinet or made into a power supply unit with a ring-shaped interval, and the core part adopts load switch and fuse, which has the advantages of simple structure, small size, low price, improved power supply parameters and performance, power supply safety, etc. When the ring main unit is working, the electrical components inside it are in a relatively closed environment, and air flow is only relied on the air vent on the door. Since the electrical components generate a lot of heat during operation in the cabinet, the natural convection cooling effect in the cabinet is poor when relying on the air vent for heat dissipation, and hot air accumulates in the cabinet, reducing the stability of the electrical component performance during operation and affecting the heat dissipation efficiency in the cabinet. SUMMARY

[0003] The purpose of the present application is to provide a primary and secondary fusion complete ring main unit to solve the problems in the background art.

[0004] To solve the above technical problems, the present application is realized by the following technical scheme: The present application is a primary and secondary fusion complete ring main unit, which comprises a main body and further comprises: A limiting mechanism is installed on the side wall of the main body to achieve heat dissipation during equipment operation. An activity mechanism is installed on the side wall of the limiting mechanism to prevent hot air from flowing back and diffusing along the side wall of the limiting mechanism during heat dissipation.

[0005] Further, the main body comprises: A closing assembly is installed on the front of the main body to dissipate heat inside the cabinet after it is closed. A guide assembly is installed on the side wall of the closing assembly to guide the flow of external air.

[0006] Further, the limiting mechanism comprises a limiting frame installed on the side wall of the closing assembly, and further comprises: A rotating assembly is installed on the side wall of the limiting frame to suck the heat inside the main body and accelerate the discharge of heat when the air flows.

[0007] Further, the activity mechanism comprises an activity plate installed on the top of the guide assembly, and further comprises: A flexible assembly is installed on the side wall of the activity plate to prevent the activity mechanism from colliding with the closing assembly during operation.

[0008] Furthermore, the closing assembly includes four boxes on the front of the main body, the four boxes are hinged in pairs, each pair of boxes is hinged to the side wall of the main body, and an inclined plate is fixedly connected to the side of the box near the main body. The side wall of the box door has several air vents and several air inlets.

[0009] Furthermore, the guide assembly includes an arc-shaped triangular plate bolted to the side of the door near the main body, with a rectangular frame fixedly connected to the top of the arc-shaped triangular plate; The side wall of the arc-shaped triangle is rotatably connected to two rotating plates, and the rectangular frame is set at an angle at the top of the arc-shaped triangle.

[0010] Furthermore, the limiting frame is fixedly connected to the top of the rectangular frame, and several rectangular grooves are opened on the side wall of the limiting frame. Several rubber sheets are fixedly connected to the side of the limiting frame near the door. The limiting frame is bolted to the side wall of the door, and the limiting frame enables the heating element of the main body to form an independent hot air rising channel in the main body.

[0011] Furthermore, the rotating assembly includes two central shafts fixedly connected to the side wall of the limiting frame, and a torsion plate is rotatably connected to the outer surface of the central shafts; The side wall of the twisted plate is rotatably connected to a connecting lug, and the center plate is rotatably connected inside the connecting lug. By utilizing the curved structure on the surface of the twisted plate, the wind-receiving area of ​​the twisted plate and the rising gas is increased.

[0012] Furthermore, the movable plate is rotatably connected between the two center plates, and four linear springs are fixedly connected to the side of the movable plate near the limiting frame. The ends of the four linear springs away from the movable plate are fixedly connected to the side wall of the limiting frame. The side wall of the movable plate has several round holes, and a horizontal plate is fixedly connected inside the round holes. A bending spring is fixedly connected to the side wall of the horizontal plate.

[0013] Furthermore, the bottom of the movable plate is slidably connected between two rotating plates, and the flexible component includes several flexible bags fixedly connected to the side of the movable plate away from the limiting frame, with the several flexible bags arranged at equal intervals; The flexible bag has a conical ring fixedly connected inside, and a flow channel is provided between the conical ring and the flexible bag.

[0014] The present invention has the following beneficial effects: 1. In this invention, external air is rapidly drawn into the channel through the air inlet, and the two are mixed and move upward at a higher speed. When the mixed gas flows upward, it will drive the heat inside the main body to be discharged outward through the air outlet under the tilting guidance of the inclined plate, thereby accelerating the heat dissipation efficiency inside the main body and ensuring the stability of the operation of the electrical components inside the main body.

[0015] 2. In this invention, when the movable plate slides away from the limiting frame, the movable plate will form a negative pressure suction force within the limiting frame. This causes the rubber sheet to open and allow the hot gas inside the main body to enter between the movable plate and the limiting frame through multiple rectangular grooves on the limiting frame, and flow upwards rapidly. When the reciprocating motion of the movable plate draws the heat inside the main body into the space between the movable plate and the limiting frame, it can accelerate the heat dissipation speed of the main body and further improve the heat dissipation efficiency of the main body.

[0016] 3. In this invention, when gas enters the flexible bag, it can reduce the situation where gas entering the channel from the outside collides with the side wall of the movable plate during the resetting process, forming turbulent airflow and flowing downwards. This ensures that the gas is continuously discharged through this channel while reducing the situation where the gas flow is obstructed in this channel, thereby improving the stability of heat dissipation when discharging gas and improving the continuity and stability of the gas flow when discharging gas.

[0017] 4. This invention, by slowing down the shrinkage speed of the flexible bag, enables a flexible buffer layer to be formed between the movable plate and the box door when the movable plate is pushed and slid. This reduces the large collision force between the movable plate and the side wall of the box door during the reciprocating sliding process, reduces the impact of the movable plate on the box door during the reciprocating sliding, reduces the vibration and noise generated by the equipment during operation, and improves the reliability of the equipment and its internal structure during operation.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 9 As shown, the present invention is a primary and secondary integrated ring network box, including a main body 1, and further including: Restriction mechanism 2 is installed on the side wall of the main body 1 and is used to dissipate heat when the equipment is working; The movable mechanism 3 is installed on the side wall of the limiting mechanism 2 to prevent hot air from flowing back and spreading along the side wall of the limiting mechanism 2 during the heat dissipation process.

[0024] Entity 1 includes: Closure component 11 is installed on the front of the main body 1 and is used to dissipate heat inside the box after it is sealed. The guide component 12 is installed on the side wall of the closure component 11 and is used to guide the gas entering from the outside.

[0025] The limiting mechanism 2 includes a limiting frame 201 disposed on the side wall of the closing component 11, and the limiting mechanism 2 also includes: Rotating component 21 is installed on the side wall of the limiting frame 201 and is used to drive the moving mechanism 3 to draw heat from the inside of the main body 1 when the gas flows, thereby accelerating the heat discharge.

[0026] The active mechanism 3 includes an active plate 301 disposed on top of the guide assembly 12, and the active mechanism 3 also includes: The flexible component 31 is installed on the side wall of the movable plate 301 to prevent the movable mechanism 3 from colliding with the closing component 11 during operation.

[0027] The closing assembly 11 includes four boxes 111 disposed on the front of the main body 1. The four boxes 111 are arranged in pairs and are hinged together. Each pair of boxes 111 is hinged to the side wall of the main body 1. An inclined plate 112 is fixedly connected to the side of the box 111 closest to the main body 1. The side wall of the box door 111 has several air outlets 113 and several air inlets 114. First, the staff installs a filter screen at the entrance of the air inlet 114. Then, the limiting frame 201 and the arc-shaped triangular plate 121 are bolted to the side wall of the box door 111. At the same time, a rubber sealing strip is installed on the side wall of the box door 111.

[0028] The guide assembly 12 includes an arc-shaped triangular plate 121 bolted to the side of the door 111 near the main body 1, and a rectangular frame 122 is fixedly connected to the top of the arc-shaped triangular plate 121. The side wall of the arc-shaped triangular plate 121 is rotatably connected to two rotating plates 123, and the rectangular frame 122 is inclined at the top of the arc-shaped triangular plate 121.

[0029] The limiting frame 201 is fixedly connected to the top of the rectangular frame 122. Several rectangular grooves are opened on the side wall of the limiting frame 201. Several rubber sheets 202 are fixedly connected to the side of the limiting frame 201 near the door 111. The limiting frame 201 is bolted to the side wall of the box door 111. The limiting frame 201 enables the heating element of the main body 1 to form an independent hot air rising channel in the main body 1. When the twisted plate 212 is subjected to the flow of gas, the twisted plate 212 will rotate on the surface of the central shaft 211.

[0030] The rotating assembly 21 includes two central shafts 211 fixedly connected to the side wall of the limiting frame 201, and a torsion plate 212 is rotatably connected to the outer surface of the central shafts 211; The side wall of the twisted plate 212 is rotatably connected to the connecting ear 213, and the center plate 214 is rotatably connected inside the connecting ear 213. With the help of the curved structure on the surface of the twisted plate 212, the wind-receiving area of ​​the twisted plate 212 and the rising gas is increased. When the twisted plate 212 rotates, it will push the movable plate 301 through the center plate 214 to make it slide away from the limiting frame 201.

[0031] The movable plate 301 is rotatably connected between two center plates 214. Four linear springs are fixedly connected to the side of the movable plate 301 near the limiting frame 201. The ends of the four linear springs away from the movable plate 301 are fixedly connected to the side wall of the limiting frame 201. The side wall of the movable plate 301 has several round holes, and a horizontal plate is fixedly connected inside the round holes. A bending spring is fixedly connected to the side wall of the horizontal plate.

[0032] The bottom of the movable plate 301 is slidably connected between two rotating plates 123. The flexible component 31 includes a number of flexible bags 311 fixedly connected to the side of the movable plate 301 away from the limiting frame 201. The number of flexible bags 311 are arranged at equal distances. A conical ring 312 is fixedly connected inside the flexible bag 311. A flow channel is provided between the conical ring 312 and the flexible bag 311. When the movable plate 301 and the limiting frame 201 slide away from each other, the movable plate 301 will form a negative pressure suction force in the limiting frame 201. After the rubber sheet opens, the hot gas in the main body 1 enters between the movable plate 301 and the limiting frame 201 through multiple rectangular grooves on the limiting frame 201.

[0033] In use, the staff first installs a filter screen at the inlet of the air inlet 114. Then, the limiting frame 201 and the arc-shaped triangular plate 121 are bolted to the side wall of the door 111. At the same time, a rubber sealing strip is installed on the side wall of the door 111. After the door 111 is closed to the main body 1, the heat generated inside the main body 1 will flow upward and be discharged outward through the air outlet 113. Meanwhile, the outside air will enter the interior of the main body 1 through the air inlet 114, thereby achieving the purpose of heat dissipation inside the main body 1.

[0034] When external air enters the main body 1 through the air inlet 114, part of the incoming air flows upward along the inclined surface of the arc-shaped triangular plate 121 and enters the space between the limiting frame 201 and the movable plate 301. The other part of the air, guided by the curved surface of the arc-shaped triangular plate 121, enters the interior of the main body 1 to dissipate heat from the electrical components inside. Simultaneously, as the air, guided by the arc-shaped triangular plate 121, enters the space between the movable plate 301 and the limiting frame 201 and flows upward, the hot air inside the main body 1 also rises and flows through the rectangular... The gas enters the channel between the limiting frame 201 and the movable plate 301. At this time, the rising gas in the channel accelerates upwards. The accelerated airflow in the channel forms a low-pressure zone at the inlet at the bottom of the movable plate 301 and the limiting frame 201. This low-pressure zone can create a suction force through the outer area between the rectangular frame 122 and the two rotating plates 123, actively drawing hot air from inside the main body 1 into the channel between the movable plate 301 and the limiting frame 201. Simultaneously, external air can be accelerated into this channel through the air inlet 114, causing the two to mix and move upwards at a higher speed, exhibiting… Figure 8 In the flow state, when the mixed gas flows upward, it will drive the heat inside the main body 1 to be discharged outward through the air outlet 113 under the tilting guidance of the inclined plate 112, thereby accelerating the heat dissipation efficiency inside the main body 1 and ensuring the stability of the operation of the electrical components inside the main body 1.

[0035] When the gas flows rapidly upward between the movable plate 301 and the limiting frame 201, the flowing gas impacts the side walls of the two tortuous plates 212. When the tortuous plates 212 are subjected to the gas flow, they rotate on the surface of the central shaft 211. During rotation, the tortuous plates 212 push the movable plate 301 through the central plate 214, causing it to slide away from the limiting frame 201. At this time, the linear springs on the movable plate 301 are in a stretched state. When the tortuous plates 212 change from an inclined state to an approximately horizontal state and push the movable plate 301, the movable plate 301 will be reset under the contraction of multiple linear springs. At this time, the movable plate 301 will slide back and forth during the gas flow. When 301 is reset, it will compress the gas between the movable plate 301 and the limiting frame 201. At this time, the rubber sheet on the limiting frame 201 will close, and the gas in this channel will continue to flow upward. When the movable plate 301 and the limiting frame 201 slide away from each other, the movable plate 301 will form a negative pressure suction force in the limiting frame 201, causing the rubber sheet to open and allowing the hot gas in the main body 1 to enter between the movable plate 301 and the limiting frame 201 through multiple rectangular grooves on the limiting frame 201, and flow upward quickly. When the reciprocating motion of the movable plate 301 draws the heat inside the main body 1 into the space between the movable plate 301 and the limiting frame 201, it can accelerate the heat dissipation speed inside the main body 1 and further improve the heat dissipation efficiency inside the main body 1.

[0036] When the movable plate 301 is pushed and resets, the reset of the movable plate 301 will cause multiple flexible bags 311 to reset synchronously. When the multiple flexible bags 311 reset with the movable plate 301, the movable plate 301 will be in an open state under the push of the bending spring. At the same time, during the reset process, the opening of the multiple flexible bags 311 will allow the gas flowing between the movable plate 301 and the limiting frame 201 to enter the flexible bags 311 through the center and edge of the conical ring 312. When the gas enters the flexible bags 311, it can reduce the situation where the gas entering this channel from the outside during the reset process of the movable plate 301 will collide with the side wall of the movable plate 301 and form turbulent airflow, and flow downward back. This ensures that the gas is continuously discharged through this channel while reducing the situation where the gas flow is obstructed in this channel, thereby improving the stability of heat dissipation when discharging gas and improving the continuity and stability of the gas flow when discharging gas.

[0037] When the tortuous plate 212 pushes the movable plate 301 to slide through the central plate 214, the sliding of the movable plate 301 will cause the flexible bag 311 to slide synchronously. At this time, the movable plate 301 will squeeze the side wall of the box door 111 through the flexible bag 311. When the flexible bag 311 is squeezing the side wall of the box door 111, the gas inside the flexible bag 311 will be squeezed outward through the conical ring 312. Since the conical ring 312 is a conical structure, when the flexible bag 311 is squeezed and the gas inside flows outward, the flow of gas will push the conical ring 312 to slide outward and cause the flexible bag 311 to wrinkle. At this time, the outer wall of the conical ring 312 will be in contact with the round hole. When the inner diameter of the conical ring 312 is in contact with the outer diameter of the flexible bag 311, the gas can only flow outward through the small-diameter channel in the middle of the conical ring 312. At the same time, the conical ring 312 also blocks the gas flowing outward from the flexible bag 311, causing it to flow out slowly. This also slows down the contraction speed of the flexible bag 311. As a result, when the movable plate 301 is pushed and slid, a flexible buffer layer is formed between the movable plate 301 and the box door 111. This reduces the large collision force between the movable plate 301 and the side wall of the box door 111 during the reciprocating sliding process, reduces the impact of the movable plate 301 on the box door 111 during the reciprocating sliding process, reduces the vibration and noise generated by the equipment during operation, and improves the reliability of the equipment and its internal structure during operation.
