Technical Field

[0001] The invention relates to the field of electrical technology, in particular to a dustproof and heat dissipation component for an electric power metering box. Background Art

[0002] The power cabinet is a cabinet used to store various electrical devices. There are many electrical components inside it, and the current and voltage are high. The temperature inside the cabinet rises quickly. If the heat inside the cabinet is not dissipated in time, the internal components will be affected by high temperature for a long time and age, affecting the safety of electricity use.

[0003] Existing power cabinets have a relatively simple heat dissipation method, usually using fans for heat dissipation. This method requires opening the power cabinet, which not only consumes energy, but also easily causes external dust to enter the power cabinet, affecting the operation of electronic components in the power cabinet. There is also a heat dissipation method that directly exposes the heat sink to the outside world, but the heat dissipation effect of this method is difficult to guarantee. Summary of the invention

[0006] Furthermore, the heat dissipation device includes a dust cover, which is fixedly installed on both sides of the power cabinet. The side of the dust cover away from the power cabinet is movably connected to a sealing door through a hinge. The bottom of the dust cover is connected through an exhaust pipe. A desiccant placement box is fixedly arranged in the middle of the exhaust pipe, and a plurality of desiccant boxes are plugged into the desiccant placement box.

[0007] Furthermore, through grooves are provided on both sides of the power cabinet, an exhaust fan is movably arranged in the through grooves, a rotating shaft is fixedly connected to a side wall facing the exhaust fan, a gear is fixedly connected to a side of the rotating shaft away from the exhaust fan, a fixing rod is fixedly provided on the inner wall of the power cabinet, and the rotating shaft is throughly connected to the fixing rod.

[0008] Furthermore, the wind power generation device includes a generator, which is fixedly mounted on the bottom end of the inner wall of the column. The top end of the rotor of the generator is fixedly connected to the bottom end of the rotating cylinder. A plurality of exhaust holes are opened in the middle of the rotating cylinder, and a metal mesh is fixedly mounted on each of the exhaust holes.

[0009] Furthermore, a gear ring is fixedly installed on the outer wall of the rotating cylinder, and the gear ring is located above the exhaust hole. Half-moon wheels are fixedly connected at high positions on the outer walls of both sides of the rotating cylinder. The top cross-section of the half-moon wheel is crescent-shaped, and a through hole is opened at the bottom of the inner wall of the half-moon wheel. The half-moon wheel is fixedly connected to an air duct through the through hole at the bottom, and the air duct is connected to the rotating cylinder through and through.

[0010] Furthermore, a rain collecting funnel is fixedly connected to the top of the rotating cylinder, and a plurality of drainage holes are opened at a lower position through the outer side of the rotating cylinder, and the drainage holes are in a circular array.

[0011] Furthermore, the dehumidification device includes a spring, which is fixedly installed at the bottom of the inner wall of the rotating cylinder. The top of the spring is fixedly connected to a water collecting trough, and the top of the water collecting trough is fixedly connected to a sealing ring through a connecting rod. A limit block is fixedly installed on the inner wall of the rotating cylinder.

[0012] Furthermore, the lighting device includes a support frame, which is fixedly mounted on a side of the power cabinet away from the cabinet door, a solar cell panel is fixedly mounted on the top end of the support frame, and an LED lamp is fixedly mounted on the bottom end of the support frame.

[0013] Furthermore, a waterproof rubber ring is fixedly installed on the top of the power cabinet.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. Under normal conditions: the components in the power cabinet will generate heat, which will cause the central air pressure inside the power cabinet to be too low, and there is a high and low pressure difference between the rain collecting funnel and the exhaust pipe. Therefore, the airflow will enter the power cabinet through the bottom of the exhaust pipe to achieve the purpose of cooling the components in the power cabinet from bottom to top, thereby improving the heat dissipation efficiency and saving energy.

[0016] 2. When encountering windy weather: the wind drives the half-moon wheel and the rotating cylinder to rotate counterclockwise as a whole, the rotating cylinder drives the gear ring to rotate, the gear ring drives the gear to rotate, and the gear drives the exhaust fan to rotate. Because the blades of the exhaust fans on both sides are tilted in opposite directions, the exhaust fans on both sides absorb and discharge the hot gas in the power cabinet, and the airflow blown by the exhaust fan pushes the sealing door to open. The hot air flow in the power cabinet is discharged through the rectangular notches on both sides of the dust cover. At this time, a negative pressure state is formed in the center of the power cabinet, and the external cold air passes through the through hole at the bottom of the inner wall of the half-moon wheel, enters the rotating cylinder through the air guide pipe, and enters the power cabinet through the exhaust hole, so as to achieve the purpose of cooling the components in the power cabinet from top to bottom by the cold air flow, thereby saving energy and further improving the heat dissipation efficiency.

[0017] 3. When it rains: Rainwater enters the rotating drum through the rainwater collecting funnel. Because the rotating drum is made of heat-conducting materials, the rainwater can also cool down the inner wall of the rotating drum when it flows through the rotating drum in the power cabinet, further improving the heat dissipation efficiency. The rainwater flows through the inner wall of the rotating drum to achieve the purpose of dust removal on the inner wall of the rotating drum.

[0018] 4. By setting up a water pool and a metal mesh membrane, external dust can be filtered to reduce the dust in the air from entering the power cabinet.

[0019] 5. By utilizing wind power to drive the generator to generate electricity, the energy generated by the generator is input into the battery of the solar panel for use in nighttime lighting, which greatly improves energy utilization and saves more energy. BRIEF DESCRIPTION OF THE DRAWINGS

The heat dissipation device 2 is mainly used for dissipating the heat inside the electric power cabinet 103, and the cooperation of the heat dissipation device 2 and the water pool 1 can prevent external dust from entering the electric power cabinet 103. The end of the drain pipe 102 away from the column 101 is penetrated and connected with the heat dissipation device 2.

The lighting device 5 is fixedly installed on the side of the power cabinet 103 away from the cabinet door.

[0030] The heat dissipation device 2 includes a dust cover 201, which is fixedly installed on both sides of the power cabinet 103. Rectangular slots are opened on both sides of the dust cover 201. A sealing door 202 is movably connected to the side of the dust cover 201 away from the power cabinet 103 through a hinge. Under normal conditions, the sealing door 202 and the dust cover 201 naturally fit together to achieve the effect of sealing the rectangular slot. An exhaust pipe 203 is opened at the bottom of the dust cover 201, and a desiccant placement box 204 is fixedly set in the middle of the exhaust pipe 203. Several desiccant boxes 205 are plugged into the desiccant placement box 204, and a number of air holes are evenly opened on the surface of the desiccant box 205. When the desiccant needs to be replaced, the desiccant box 205 is directly taken out and a new desiccant box 205 is put in, which is fast to replace and easy to operate.

[0031] Through slots are provided on both sides of the power cabinet 103, and exhaust fans 206 are movably arranged in the through slots. A rotating shaft 207 is fixedly connected to a side wall facing the exhaust fan 206, and a gear 208 is fixedly connected to the side of the rotating shaft 207 away from the exhaust fan 206. A fixing rod 209 is fixedly provided on the inner wall of the power cabinet 103, and the rotating shaft 207 is connected through the fixing rod 209. There are four fixing rods 209, wherein the fixing rods 209 on the left and right sides are symmetrical to each other, and the two fixing rods 209 on the outer sides and the two fixing rods 209 on the center are fixedly connected to each other. The fixing rods 209 are respectively abutted against one side of the exhaust fan 206 and the gear 208 to prevent the exhaust fan 206, the rotating shaft 207 and the gear 208 from being offset to the left and right, and the blades of the two exhaust fans 206 are tilted in opposite directions, so that when the rotating cylinder 302 rotates counterclockwise, it drives the gear ring 305 to rotate, and the rotation of the gear ring 305 drives the gear 208 to rotate, and the rotation of the gear 208 drives the fixing rod 209 and the exhaust fan 206 to rotate, and the exhaust fan 206 is always in a state of extracting the hot air in the power cabinet 103 to the outside.

[0032] The wind power generation device 3 includes a generator 301, which is fixedly mounted on the bottom end of the inner wall of the column 101. The top end of the rotor of the generator 301 is fixedly connected to the bottom end of the rotating cylinder 302. A plurality of exhaust holes 303 are opened in the middle of the rotating cylinder 302. Metal mesh films 304 are fixedly mounted on the exhaust holes 303. The metal mesh films 304 are provided to reduce dust in the air from entering the power cabinet 103.

[0033] A gear ring 305 is fixedly installed on the outer wall of the rotating cylinder 302, and teeth are fixedly installed on the bottom of the gear ring 305. The gear ring 305 is meshed with the gear 208. The gear ring 305 is located above the exhaust hole 303. Half-moon wheels 306 are fixedly connected to the high positions of the outer walls on both sides of the rotating cylinder 302. The top cross-section of the half-moon wheel 306 is crescent-shaped, and a through hole is opened at the bottom of the inner wall of the half-moon wheel 306. The half-moon wheel 306 is fixedly connected to an air guide pipe 307 through the through hole at the bottom. The air guide pipe 307 is connected to the rotating cylinder 302 through and through. By setting the half-moon wheel 306 to a crescent shape, when there is wind, the half-moon wheel 306 and the rotating cylinder 302 can only rotate counterclockwise.

[0034] A rain collecting funnel 308 is fixedly connected to the top of the rotating cylinder 302. Since air often circulates through the inner wall of the rotating cylinder 302, dust accumulates on the inner wall of the rotating cylinder 302. By setting the rain collecting funnel 308, the inner wall of the rotating cylinder 302 can be flushed when it rains. Several drainage holes are opened at a lower position on the outside of the rotating cylinder 302. The drainage holes are in a circular array to facilitate rainwater to flow out through the drainage holes.

[0035] The dehumidification device 4 includes a spring 401, which is fixedly installed at the bottom of the inner wall of the rotating cylinder 302. The top of the spring 401 is fixedly connected to a water collecting tank 402. The top of the water collecting tank 402 is fixedly connected to a sealing ring 403 through a connecting rod. A limit block 404 is fixedly installed on the inner wall of the rotating cylinder 302. A leakage hole is opened at a lower position on the outer side of the water collecting tank 402. The leakage holes are in an annular array, and the leakage holes on the water collecting tank 402 are vertically colinear with the drainage holes on the rotating cylinder 302. Under normal conditions, the outer wall of the water collecting tank 402 is sealed and movably connected to the inner wall of the rotating cylinder 302, and the outer wall of the rotating cylinder 302 is sealed and movably connected to the inner wall of the column 101. Rainwater in the rain collecting funnel 308 falls into the water collecting tank 402. The water collecting tank 4 02 will overcome the thrust of spring 401 and move downward. When the leakage hole on the sump 402 and the drainage hole on the rotating drum 302 reach the same horizontal position, and the drainage hole of the rotating drum 302 corresponds to the aperture of the drainage pipe 102, the rainwater in the sump 402 will pass through the leakage hole on the sump 402, the drainage hole on the rotating drum 302, the drainage pipe 102 and finally flow into the water tank 1 through the exhaust pipe 203. When the sump 402 moves downward, it will drive the sealing ring 403 to move downward. When the leakage hole on the sump 402 and the drainage hole on the rotating drum 302 reach the same horizontal position, the sealing ring 403 will block the exhaust hole 303 to prevent moisture in the rainwater from entering the power cabinet 103 from the exhaust hole 303.

[0036] The lighting device 5 includes a support frame 501, which is fixedly installed on a side of the power cabinet 103 away from the cabinet door. A solar panel 502 is fixedly installed on the top of the support frame 501, and an LED lamp 503 is fixedly installed on the bottom of the support frame 501. A battery is fixedly installed at the bottom of the solar panel 502. The solar panel 502 is electrically connected to the generator 301. The electric energy generated by the generator 301 is transmitted to the battery at the bottom of the solar panel 502 for storage so as to be used by the LED lamp 503 for night lighting.

[0037] Working principle of the present invention:

[0038] Under normal conditions: the components in the power cabinet 103 will generate heat, and the gas in the power cabinet 103 will be heated and discharged through the exhaust hole 303, and then through the rotating cylinder 302 and the rain collecting funnel 308 in turn. This will cause the central air pressure inside the power cabinet 103 to be too low, and there is a high-low air pressure difference between the rain collecting funnel 308 and the exhaust pipe 203. Therefore, the airflow will enter the desiccant placement box 204 through the bottom of the exhaust pipe 203 for dehumidification, and then enter the power cabinet 103 through the dust cover 201, so as to achieve air circulation in the power cabinet 103, and exchange of hot and cold gases, so as to achieve the purpose of heat dissipation of the components in the power cabinet 103 from bottom to top by the cold airflow.

[0039] When encountering windy weather: the wind drives the half-moon wheel 306 and the rotating cylinder 302 to rotate counterclockwise as a whole, the rotating cylinder 302 drives the gear ring 305 to rotate, the gear ring 305 drives the gear 208 to rotate, and the gear 208 drives the exhaust fan 206 to rotate. Because the blades of the exhaust fans 206 on both sides are inclined in opposite directions, the exhaust fans 206 on both sides absorb and discharge the hot gas in the power cabinet 103, and the airflow blown by the exhaust fans 206 pushes the sealing door 202 to open, and the hot air flow in the power cabinet 103 is discharged through the rectangular notches on both sides of the dust cover 201. At this time, a negative pressure state is formed in the center of the power cabinet 103, and the external cold air passes through the through hole at the bottom of the inner wall of the half-moon wheel 306, passes through the air guide pipe 307, enters the rotating cylinder 302, and enters the power cabinet 103 through the exhaust hole 303, so as to achieve the purpose of cooling the components in the power cabinet 103 from top to bottom by the cold air flow.

[0040] In rainy weather: Rainwater enters the rotating drum 302 through the rainwater collecting funnel 308, and washes away the dust on the inner wall of the rotating drum 302. Because the rotating drum 302 is made of heat-conducting materials, the rainwater can also cool down the inner wall of the rotating drum 302 when it flows through the rotating drum 302 in the power cabinet 103, so as to achieve the purpose of heat dissipation inside the power cabinet 103. Since there is a lot of moisture in the air during rainy weather, the rainwater will eventually flow into the water collecting tank 402. The spring 401 moves downward under the action of gravity until the leakage hole on the water collecting trough 402 is flush with the drainage hole on the rotating drum 302, and the rainwater will flow into the pool 1 through the drainage pipe 102 and finally through the exhaust pipe 203. At the same time, due to the downward displacement of the water collecting trough 402, the sealing ring 403 will be driven to block the exhaust hole 303, thereby minimizing the moisture in the rainwater from entering the power cabinet 103 through the exhaust hole 303 and causing corrosion of the components in the power cabinet 103.
