Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical energy metering box protection technology, specifically to an electrical energy metering box with moisture-proof function. Background Technology
[0002] A metering box is a combination of current transformers and measuring instruments and meters, including an energy meter, voltage and current transformers for metering and their secondary circuits, cabinets and boxes, etc. It accurately measures and records the use of electrical energy through the internal energy meter. When operating, metering boxes require moisture-proofing. Traditional electricity metering boxes typically use rubber sealing strips around the door to keep the box relatively sealed, relying only on small side vents for air circulation to achieve moisture protection. However, due to the sealed nature of the box and the large amount of heat generated by the electrical components inside, moisture can easily condense and accumulate on the inner wall of the box due to temperature differences between the inside and outside during prolonged operation, thus affecting the moisture-proofing efficiency of the metering box. Summary of the Invention
[0003] The purpose of this invention is to provide an energy metering box with moisture-proof function to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a moisture-proof electricity metering box, comprising a main body, with several ventilation openings on the left and right inner walls of the main body, and further comprising: A rotating mechanism is installed inside the main body to improve the moisture resistance of the equipment. The rotating mechanism includes several limiting plates fixedly connected to the inner walls of the left and right sides of the main body, and the limiting plates are arranged symmetrically in pairs. The auxiliary mechanism is installed inside the main body to prevent periodic gas leakage during the moisture-proofing process. The auxiliary mechanism includes a rectangular frame fixedly connected inside the main body, with a thin plate on the top of the rectangular frame.
[0005] Furthermore, the main body includes: The active component is installed inside the main body to prevent moisture condensation.
[0006] Furthermore, the rotating mechanism also includes: A guiding component is installed on the side wall of the limiting plate to guide the incoming gas.
[0007] Furthermore, the auxiliary mechanisms also include: A sliding assembly is installed on top of the thin plate to prevent the thin plate from vibrating periodically when gas flows. The pusher assembly is installed at the bottom of the thin plate to reduce backflow of rising gas.
[0008] Furthermore, the active component includes a water collection chamber fixedly connected to the inner walls of the left and right sides of the main body, and the water collection chamber is connected to the outside of the main body through the side wall of the main body; The water collection tank is internally fixed with rubber pads; The rubber pad allows condensed water droplets to drain outwards and prevents external gases from entering the interior of the body through this channel.
[0009] Furthermore, a perforated plate is slidably connected to the top of the water collection tank, and an auxiliary spring is fixedly connected to the side wall of the perforated plate. The end of the auxiliary spring away from the perforated plate is fixedly connected to the inner wall of the main body.
[0010] Furthermore, the guide assembly includes a limiting shaft rotatably connected between the two limiting plates; An inclined plate is fixedly connected to the outer surface of the limiting shaft, and a bending plate is fixedly connected to the side of the inclined plate near the mesh plate. In its initial state, the guide plate is set at an angle. The opening formed between the curved plate and the inclined plate can be aligned with the vent to guide the faster-flowing airflow back.
[0011] Furthermore, two inclined plates are fixedly connected to the bottom of the thin plate, and the inclined plates are in contact with the side wall of the perforated plate; The sliding assembly includes a limiting frame rotatably connected to the top of the thin plate, and a T-shaped rod is fixedly connected to the inner top wall of the limiting frame.
[0012] Furthermore, a hollow cylinder is slidably connected to the outer surface of the T-shaped rod, and several tapered holes are opened on the outer surface of the hollow cylinder; The top of the hollow cylinder is fixedly connected to the top inner wall of the main body.
[0013] Furthermore, the bottom of the thin plate is provided with several sliding grooves, which are arranged in pairs at equal distances; The pushing component includes a fixed rod that is slidably connected inside the sliding groove, a center plate that is rotatably connected to the outer surface of the fixed rod, and a V-shaped plate that is rotatably connected between the two center plates.
[0014] The present invention has the following beneficial effects: 1. In this invention, incoming air and rising moisture from inside the main body come into contact with the perforated plate. At this time, the water vapor in the moisture condenses on the surface of the perforated plate and flows downward along its condensation surface, and is discharged outward through the water collection chamber. This further reduces the penetration of moisture into the main body, and also reduces the situation where moisture condenses and accumulates on the inner wall of the main body due to the temperature difference between the inside and outside of the main body, thus improving the moisture-proof efficiency of this device during operation.
[0015] 2. In this invention, the recess between the curved plate and the inclined plate will guide the rapidly entering gas back after it comes into contact with the fast-flowing wind. By reversing the airflow, the situation where the fast-flowing gas blows away the water vapor condensed on the mesh plate when it enters the main body through the vent can be reduced, thus further ensuring moisture-proof stability and moisture-proof efficiency.
[0016] 3. In this invention, when the T-shaped rod slides inside the hollow cylinder to form a negative pressure, external gas will slowly enter the hollow cylinder. At this time, the T-shaped rod can limit and slow down the resetting speed of the thin plate, thereby reducing the reciprocating vibration of the thin plate when the gas flows between the thin plate and the rectangular frame. This further ensures the stability of gas flow during moisture removal and ventilation, and also improves the safety of the equipment during operation and enhances the moisture-proof strength.
[0017] 4. In this invention, when the gas flows upward, the gas that comes into contact with the bottom of the thin plate and diffuses is blocked, thereby reducing the diffusion and backflow of the gas after it collides with the side wall of the thin plate during its ascent. By blocking the diffused gas, the excessive accumulation of gas in the main body during diffusion and backflow can be reduced. At the same time, the continuity of gas discharge can be ensured, further improving the discharge of hot and humid air and the efficiency of moisture prevention.
[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

Detailed Implementation
[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 Figures 1-10 As shown, the present invention is an energy metering box with moisture-proof function, including a main body 1, wherein the left and right inner walls of the main body 1 are provided with a plurality of ventilation openings 101, and further includes: Rotating mechanism 2 is installed inside the main body 1 to improve the moisture resistance of this equipment. The rotating mechanism 2 includes several limiting plates 201 fixedly connected to the inner walls of the left and right sides of the main body 1. The limiting plates 201 are arranged symmetrically in pairs. Auxiliary mechanism 3 is installed inside the main body 1 to prevent periodic gas leakage during the moisture-proof process; The auxiliary mechanism 3 includes a rectangular frame 301 fixedly connected inside the main body 1, and a thin plate 311 is provided on the top of the rectangular frame 301.
[0024] Entity 1 includes: Active component 11 is installed inside the main body 1 to prevent moisture condensation.
[0025] The rotating mechanism 2 also includes: The guide component 21 is installed on the side wall of the limiting plate 201 and is used to guide the incoming gas.
[0026] Auxiliary mechanism 3 also includes: The sliding component 31 is installed on the top of the thin plate 311 to prevent the thin plate 311 from vibrating periodically when the gas flows. A pusher assembly 32 is installed at the bottom of the thin plate 311 to reduce backflow of rising gas.
[0027] The active component 11 includes a water collection tank 111 fixedly connected to the inner walls of the left and right sides of the main body 1. The water collection tank 111 is connected to the outside of the main body 1 through the side wall of the main body 1. Among them, the water collection tank 111 is internally fixedly connected with a rubber pad; The rubber pad allows condensed water droplets to drain outwards and prevents external gases from entering the interior of the body through this channel.
[0028] A perforated plate 112 is slidably connected to the top of the water collection tank 111, and an auxiliary spring 113 is fixedly connected to the side wall of the perforated plate 112. The end of the auxiliary spring 113 away from the perforated plate 112 is fixedly connected to the inner wall of the main body 1. The auxiliary spring 113 located in the top area of the perforated plate 112 will push the top of the perforated plate 112, causing the perforated plate 112 to tilt. At this time, the tilted perforated plate 112 can increase the contact area with the rising airflow.
[0029] The guide assembly 21 includes a limiting shaft 211 that is rotatably connected between two limiting plates 201; An inclined plate 212 is fixedly connected to the outer surface of the limiting shaft 211, and a curved plate 213 is fixedly connected to the side of the inclined plate 212 near the mesh plate 112. In its initial state, the guide plate is inclined. The opening formed between the curved plate 213 and the inclined plate 212 can be aligned with the vent 101 to guide the faster-flowing airflow back. When there is a strong wind in the external environment of the main body 1 and the wind speed is fast, the fast-flowing gas will impact the side wall of the inclined plate 212. At this time, the top area of the inclined plate 212 will drive the bending plate 213 to rotate downward through the limiting shaft 211. At this time, the recess between the bending plate 213 and the inclined plate 212 will face the direction of the vent 101.
[0030] Two inclined plates are fixedly connected to the bottom of the thin plate 311, and the inclined plates are in contact with the side wall of the mesh plate 112; The sliding assembly 31 includes a limiting frame 312 rotatably connected to the top of the thin plate 311, and a T-shaped rod 313 is fixedly connected to the inner top wall of the limiting frame 312. When the gas pushes the thin plate 311 to slide upward, the sliding of the thin plate 311 will drive the T-shaped rod 313 to slide upward through the limiting frame 312. When the T-shaped rod 313 slides upward, it will squeeze the gas inside the hollow cylinder 314.
[0031] A hollow cylinder 314 is slidably connected to the outer surface of the T-shaped rod 313, and a number of tapered holes are opened on the outer surface of the hollow cylinder 314; The top of the hollow cylinder 314 is fixedly connected to the top inner wall of the main body 1; When the T-shaped rod 313 slides inside the hollow cylinder 314 and forms a negative pressure, the external gas will slowly enter the hollow cylinder 314. At this time, the T-shaped rod 313 can limit and slow down the resetting speed of the thin plate 311 as it resets downward.
[0032] The bottom of the thin plate 311 has several sliding grooves, which are arranged in pairs at equal distances. The pushing component 32 includes a fixed rod 321 slidably connected inside the sliding groove, a center plate 322 rotatably connected to the outer surface of the fixed rod 321, and a V-shaped plate 323 rotatably connected between the two center plates 322.
[0033] In use, the staff first installs a filter screen inside the vent 101 to prevent external dust and insects from entering. Then, the staff installs a sealing strip on the side wall of the door. At the same time, multiple upward-blowing fans are installed at the bottom of the main body 1 as needed. When the door and the main body 1 are closed, the sealing strip will put the main body 1 in a near-completely sealed state. The fans can not only dissipate heat inside the main body 1, but also accelerate the air flow inside the main body 1. In turn, the sealing strip can seal the main body 1, achieving the purpose of moisture prevention when the main body 1 is in operation.
[0034] Initially, the vent 101 is blocked by multiple inclined plates 212. When the electrical components inside the main body 1 operate, generating more hot gas inside the main body 1, the internal air pressure of the main body 1 increases. This increased pressure pushes the thin plate 311 upwards, separating it from the rectangular frame 301. The gas then passes between the thin plate 311 and the rectangular frame 301 and exits through the top area of the main body 1. As the thin plate 311 slides upwards, it causes the two inclined plates at the bottom to move upwards simultaneously. These inclined plates then separate from the perforated plate 112, and the auxiliary spring 113 at the top of the perforated plate 112 pushes the top of the perforated plate 112, causing it to tilt. This tilted perforated plate 112 increases the contact area with the rising airflow. Then, when… When the hot and humid air inside the main body 1 is discharged from the top, the relatively dry air outside will enter the interior of the main body 1 through the vent 101. At this time, the air entering the main body 1 will flow obliquely upward under the guidance of the inclined surfaces of multiple inclined plates 212. The obliquely upward flowing air can carry away the heat inside the main body 1 and disrupt the formation of high temperature and high humidity inside the main body 1. At the same time, the air entering from the outside and the rising moisture inside the main body 1 will come into contact with the perforated plate 112. At this time, the water vapor in the moisture will condense on the surface of the perforated plate 112 and flow downward along its condensation surface, and be discharged outward through the water collection chamber 111. This can further reduce the penetration of moisture into the main body 1, and also reduce the situation where moisture condenses and accumulates on the inner wall of the main body 1 due to the temperature difference between the inside and outside, thus improving the moisture-proof efficiency of this device during operation.
[0035] When the perforated plate 112 is tilted under the push of the auxiliary spring 113, multiple tilting plates 212 will be tilted between the vent 101 and the perforated plate 112. When the external gas is in a stable flow and the flow rate is not high, the gas flowing into the main body 1 will flow through the tilted surface of the tilting plate 212. At this time, the gas will flow normally into the main body 1 and will not impact the surface of the perforated plate 112. When there is a large wind outside the main body 1 and the wind speed is fast, the faster flow of gas will impact the side wall of the tilting plate 212. At this time, the tilting plate 212 will... The top area of 2 will drive the bending plate 213 to rotate downward through the limiting shaft 211. At this time, the recess between the bending plate 213 and the inclined plate 212 will face the direction of the vent 101. When the recess between the bending plate 213 and the inclined plate 212 comes into contact with the fast-flowing wind, it will guide the fast-flowing air to be deflected. By deflecting the airflow, the situation where the fast-flowing air blows away the water vapor condensed on the mesh plate 112 when it enters the body 1 through the vent 101 can be reduced. This further ensures the stability of moisture protection and the efficiency of moisture protection.
[0036] When the gas pushes the thin plate 311 upward, the sliding of the thin plate 311 will cause the T-shaped rod 313 to slide upward through the limiting frame 312. When the T-shaped rod 313 slides upward, it will compress the gas inside the hollow cylinder 314. At this time, the gas inside the hollow cylinder 314 will be discharged outward through multiple conical holes as the T-shaped rod 313 slides. When the thin plate 311 experiences a downward sliding and reset vibration with the gas flow, the downward sliding of the thin plate 311 will cause the limiting frame 312 and the T-shaped rod 313 to slide synchronously. When the T-shaped rod 313 slides downward inside the hollow cylinder 314, the T-shaped rod 313 will be in the hollow... Negative pressure is generated inside the cylinder 314. Due to the small outer diameter of the conical hole on the hollow cylinder 314, when the T-shaped rod 313 slides inside the hollow cylinder 314 to form negative pressure, the external gas will slowly enter the interior of the hollow cylinder 314. At this time, the T-shaped rod 313 can limit and slow down the resetting speed of the thin plate 311, thereby reducing the reciprocating vibration of the thin plate 311 when the gas flows between the thin plate 311 and the rectangular frame 301. This further ensures the stability of gas flow during gas dehumidification and ventilation, and also improves the safety of the equipment during operation and enhances the moisture-proof strength.
[0037] When the gas inside the main body 1 pushes the thin plate 311 upward, the thin plate 311 will separate from the rectangular frame 301. At this time, the thin plate 311 will slightly change from an inclined state to a reverse inclined state. When the thin plate 311 is in a reverse inclined state, the V-shaped plate 323 on the thin plate 311 will slide along the inclination of the thin plate 311. When the V-shaped plate 323 slides, it will drive the two central plates 322 and the fixing rod 321 to slide closer together. At this time, a force will be formed between the two fixing rods 321 and the V-shaped plate 323. The V-shaped structure at a large angle can block the gas from diffusing as it flows upward, thus reducing the diffusion and backflow of gas after it collides with the sidewall of the thin plate 311 during its ascent. By blocking the diffused gas, excessive accumulation of gas within the main body 1 during diffusion and backflow can be reduced. At the same time, it can also ensure the continuity of gas discharge, further improving the discharge of hot and humid air and the efficiency of moisture prevention.
