Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, specifically to an electricity meter with rainproof protection function. Background Technology

[0002] Traditional electricity meters are susceptible to water damage in outdoor environments, which can lead to short circuits or data distortion. In recent years, the integration of waterproof materials and sealing structures has driven breakthroughs in electricity meter rainproof technology. However, conventional seals are prone to leakage after aging, and airtight protection can easily lead to internal condensation.

[0003] Patent publication number CN115586359A discloses a protective electricity meter, belonging to the field of electricity meter technology. It includes a device body, with a mounting plate fixedly installed on the inner wall of the device body. An electricity meter device is mounted on the top of the mounting plate, and a connecting block is fixedly installed on the back of the electricity meter device. A connecting groove is formed at the bottom of the connecting block. This protective electricity meter has a connecting block on the meter device, which connects to a conductor. In the event of a fire in the electricity meter device, the gas inside the sealing frame expands, pushing a piston and a push rod downwards. The push rod pushes a locking block away from a force plate, and under the action of a spring clip, a sliding plate moves downwards, causing the conductor to disengage from the connecting groove of the connecting block. This disconnects the conductor from the electricity meter device, preventing the circuit from becoming connected after the electricity meter device burns and deforms.

[0004] When the above-mentioned electricity meter is in use, the conductor is disconnected from the connecting groove of the connecting block in the event of a fire in the meter device. The wire will be disconnected from the meter device, which can prevent the circuit from being connected after the meter device is burned and deformed. However, it fails to take into account the situation in the long rainy season when the meter is soaked and corroded by rainwater, which may cause the meter to be damaged prematurely and thus potentially cause a safety accident. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an electricity meter with rainproof protection, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electricity meter with rainproof protection function, comprising an electricity meter body and a housing, wherein the electricity meter body is fixed to the inner wall of the housing, the upper side of the housing is fixedly connected to the lower side of the rainproof top, the upper side of the rainproof top is provided with a squeegee to prevent the rainproof top from being soaked, the lower side of the rainproof top is provided with a protective device to cover the equipment during heavy rain, and the upper side of the housing is provided with a defogging device; The wiper device includes a reciprocating screw, a threaded block, a large slider, a limit rod, a compression spring, a wiper blade, a small slider, a connecting rod, a short spring, a push claw, a long spring, an intercepting claw, a rain sensor, and a waterproof motor. The front end of the rainproof top is fixedly connected to the rear end of the waterproof motor, the rain sensor is fixed to the top of the waterproof motor, the inner side of the rainproof top is rotatably connected to one end of the reciprocating screw, and the other end of the reciprocating screw is fixedly connected to the output end of the waterproof motor.

[0007] According to the above technical solution, the outer wall of the reciprocating screw is slidably connected to the inner wall of the threaded block, the front end of the rainproof top is slidably connected to the rear end of the large slider, the upper end of the large slider is fixedly connected to the lower end of the limiting rod, the upper end of the large slider is fixedly connected to the lower end of the compression spring, the upper end of the compression spring is fixedly connected to the lower end of the scraper, and the inner wall of the scraper is slidably connected to the outer wall of the limiting rod. The reciprocating screw pulls the threaded block to move, causing the threaded block to squeeze the scraper. Through the cooperation of the large slider and the long spring, the rainwater on the rainproof top is scraped off, causing the reciprocating screw to push away the threaded block. Through the cooperation of the compression spring and the limiting rod, the scraper does not contact the rainproof top when it resets.

[0008] According to the above technical solution, the outer end of the scraper blade is slidably connected to the inner end of the small slider, the inner wall of the small slider is slidably connected to the outer wall of the connecting rod, the upper end of the connecting rod is fixedly connected to the lower end of the short spring, and the upper end of the short spring is fixedly connected to the lower end of the scraper blade, the outer wall of the connecting rod is fixedly connected to the inner wall of the push claw, the outer end of the large slider is fixedly connected to one end of the long spring, and the other end of the long spring is fixedly connected to the rainproof top, and the inner end of the rainproof top is fixedly connected to the outer end of the intercepting claw. This allows the short spring to push the push claw, causing the push claw to slide on the rainproof top, pushing away dirt such as leaves that are difficult to scrape off from the rainproof top. When the push claw resets, it passes through the intercepting claw, removing the dirt for the next round of work.

[0009] According to the above technical solution, the protective device includes a sliding plate, a sleeve plate, a strong spring, a water collection box, a water storage box, a drain hole, a bump and groove, a sliding rod, a pressure block, a return spring, and a striking block; the lower end of the rainproof top is fixedly connected to the upper end of the sleeve plate.

[0010] According to the above technical solution, the inner wall of the sleeve plate is slidably connected to the outer wall of the slide plate, the upper end of the slide plate is fixedly connected to the lower end of the strong spring, and the upper end of the strong spring is fixedly connected to the lower end of the rainproof top, the outer end of the rainproof top is fixedly connected to the inner end of the water collection box, the outer end of the slide plate is fixedly connected to the inner end of the water storage box, and a drain hole is opened on the water storage box to increase the rainwater in the water storage box. Pulling the slide plate will cover the side of the meter to prevent rainwater from seeping horizontally.

[0011] According to the above technical solution, the front end of the large slider is fixedly connected to the rear end of the bump block, the inner wall of the rainproof top is slidably connected to the outer wall of the slide rod, the outer wall of the slide rod is fixedly connected to the inner wall of the pressure block, the upper end of the slide rod is fixedly connected to one end of the return spring, and the other end of the return spring is fixedly connected to the lower side of the rainproof top, and the outer wall of the slide rod is fixedly connected to the inner wall of the striking block, so that the bump block moves and collides with the pressure block. At this time, through the cooperation of the slide rod and the return spring, the striking rod strikes the rainproof top, breaking the surface tension of the rainwater.

[0012] According to the above technical solution, the demisting device includes an air chamber, an air pipe, a filter sponge, an L-plate, a flexible switch, a controller, and a heating plate; the air chamber is detachably installed on the inner side of the sleeve plate, the inner wall of the air chamber is fixedly connected to the outer wall of the air pipe, and the interiors of the shell, air pipe, air chamber, and sleeve plate are interconnected. The inner wall of the air chamber is fixedly connected to the outer wall of the filter sponge. When the sliding plate slides in, the air inside the sleeve flows, passes through the air chamber, absorbs moisture through the filter sponge, and finally allows the air pipe to input dry air into the meter.

[0013] According to the above technical solution, the lower side of the sleeve plate is fixedly connected to the upper end of the L plate, the lower side of the L plate is slidably connected to the elastic switch, the elastic switch is electrically connected to the controller, and the rear side of the controller is fixedly connected to the front side of the housing. The upper end of the air chamber is fixedly connected to the lower end of the heating plate, and the controller is electrically connected to the heating plate, so that the slide plate slides out and moves, colliding with the elastic switch, and through the cooperation of the L plate and the controller, the heating plate is activated, so that the air chamber and the filter sponge are dried.

[0014] This invention provides an electricity meter with rainproof protection. It has the following beneficial effects: 1. This invention incorporates a squeegee device. When heavy rain occurs, a rain sensor detects the rainwater and emits an electrical signal, which is transmitted to a controller. Upon receiving the signal, the controller activates a waterproof motor, causing a reciprocating screw to rotate. This screw drives a threaded block, which in turn presses against the squeegee. Through the cooperation of a large slider and a long spring, rainwater is squeegeed off the rainproof roof, preventing water accumulation and erosion. This solves the problem of rainwater buildup and erosion of the rainproof roof over long-term use, thus preventing excessive rainwater from seeping into the meter and damaging it. When the reciprocating screw drives the threaded block at an angle... When moving upwards, the scraper blade moves upwards and resets itself through the cooperation of the compression spring and the limit rod, preventing it from contacting the rainproof roof and thus preventing the scraper blade from bringing rainwater and impurities back. At the same time, the threaded sleeve moves downwards at an angle, and through the cooperation of the short spring, the push rod moves downwards, causing the push claw to move against the top of the rainproof roof, pushing away dirt such as leaves that are difficult to scrape off the rainproof roof. This solves the problem of dirt accumulation causing the rainwater flow rate to slow down. At the same time, through the cooperation of the intercepting claw and the scraper blade, when the push claw resets, it passes through the intercepting claw to remove the dirt, making it easier for the next round of work, thereby improving the drainage efficiency of the rainproof roof.

[0015] 2. This invention incorporates a protective device. When rainwater is blown down, it is collected in a water collection box. Then, through the cooperation of a sliding plate and a strong spring, when the rainwater concentration speed exceeds the drainage speed, the sliding plate lowers to protect the heat dissipation holes on the side of the casing. This solves the problem of rainwater entering the meter through the heat dissipation holes during heavy rain, thus improving the equipment's lifespan. When the large sliding block moves downwards at an angle, it moves the convex and concave blocks, causing them to collide with the pressure block. At this time, through the cooperation of a sliding rod and a return spring, the striking rod strikes the rainproof top, solving the problem of rainwater remaining in a clump and flowing slowly due to tension in areas the scraper cannot reach. This further increases the speed at which rainwater leaves the rainproof top.

[0016] 3. This invention incorporates a defogging device. When the scraper stops scraping rainwater in, the outflow of rainwater from the water storage box exceeds the inflow, reducing the weight of the water storage box. At this time, a powerful spring pulls the sliding plate into the sleeve, injecting air from the sleeve into the air chamber. Through the absorption of moisture by the filter sponge, the air pipe finally introduces dry air into the housing. This solves the problem of unclear display on the meter screen due to high humidity during heavy rain, preventing users from having difficulty reading the meter and affecting their work. Furthermore, the sliding plate moves out and collides with the elastic switch. Through the cooperation of the L-plate and the controller, the heating plate is activated to dry the air chamber and filter sponge, solving the problem of decreased moisture filtration efficiency during continuous rainy weather, thereby improving the performance.

[0020] 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.

[0021] Please see Figures 1-8 One embodiment of the present invention is: an electric meter with rainproof protection function, including an electric meter body 1 and a housing 8. The electric meter body 1 is fixed to the inner wall of the housing 8. The upper side of the housing 8 is fixedly connected to the lower side of the rainproof top 2. The upper side of the rainproof top 2 is provided with a squeegee device 3 to prevent the rainproof top 2 from being soaked. The wiper device 3 includes a reciprocating screw 301, a threaded block 302, a large slider 303, a limiting rod 304, a compression spring 305, a wiper blade 306, a small slider 307, a connecting rod 308, a short spring 309, a pusher 310, a long spring 311, an intercepting claw 312, and a waterproof motor 6. The front end of the rainproof top 2 is fixedly connected to the rear end of the waterproof motor 6. A rain sensor 7 is fixedly mounted on the top of the waterproof motor 6. The waterproof motor 6 is electrically connected to the controller 506, and the rain sensor 7 is electrically connected to the controller 506. The inner side of the rainproof top 2 is connected to the reciprocating screw 301. One end of the reciprocating screw 301 is rotatably connected, and the other end of the reciprocating screw 301 is fixedly connected to the output end of the waterproof motor 6. The outer wall of the reciprocating screw 301 is rotatably connected to the inner wall of the threaded block 302. The front end of the rainproof top 2 is slidably connected to the rear end of the large slider 303. The upper end of the large slider 303 is fixedly connected to the lower end of the limiting rod 304. The upper end of the large slider 303 is fixedly connected to the lower end of the compression spring 305. The upper end of the compression spring 305 is fixedly connected to the lower end of the scraper 306, and the inner wall of the scraper 306 is slidably connected to the outer wall of the limiting rod 304, so that the reciprocating screw 301 drives the threaded block 6. The movement of block 302 causes the threaded block 302 to press against the scraper 306, and through the cooperation of the large slider 303 and the long spring 311, the rainwater on the rainproof roof 2 is scraped off. When the reciprocating screw 301 drives the threaded block 302 to move obliquely upward, through the cooperation of the compression spring 305 and the limiting rod 304, the scraper 306 returns to its original position and does not contact the rainproof roof 2. The outer end of the scraper 306 is slidably connected to the inner end of the small slider 307, the inner wall of the small slider 307 is slidably connected to the outer wall of the connecting rod 308, and the upper end of the connecting rod 308 is fixedly connected to the lower end of the short spring 309. The upper end of 09 is fixedly connected to the lower end of the scraper 306. The outer wall of the connecting rod 308 is fixedly connected to the inner wall of the pusher 310. The outer end of the large slider 303 is fixedly connected to one end of the long spring 311, and the other end of the long spring 311 is fixedly connected to the rainproof top 2. The inner end of the rainproof top 2 is fixedly connected to the outer end of the intercepting claw 312, so that the short spring 309 pushes the pusher 310, so that the pusher 310 slides on the rainproof top 2, pushing away the dirt that is difficult to scrape off, such as leaves, adsorbed on the rainproof top 2. When the pusher 310 resets, it passes through the intercepting claw 312, removing the dirt to facilitate the next round of work.

[0022] When heavy rain occurs, the rain sensor 7 detects the rainwater and sends an electrical signal to the controller 506. The controller 506 then starts the waterproof motor 6, causing the reciprocating screw 301 to rotate. Since the reciprocating screw 301 is not parallel to the rainproof roof 2 and tends to intersect it, the screw 301 drives the threaded block 302 to tilt and move closer to the rainproof roof 2. This causes the threaded block 302 to press against the scraper 306, and through the cooperation of the large slider 303 and the long spring 311, the scraper... The rainwater on the rain cover 2 is wiped off, preventing rainwater from accumulating, seeping and eroding the rain cover 2. This solves the problem of rainwater accumulation and erosion of the rain cover 2 after long-term use, thus avoiding the damage to the meter body 1 caused by excessive rainwater seeping into it. At the same time, when the reciprocating screw 301 drives the threaded block 302 to move obliquely upward, the scraper 306 is reset and does not contact the rain cover 2 through the cooperation of the compression spring 305 and the limit rod 304, preventing the scraper 306 from bringing rainwater and impurities back when it resets. By using a short spring 309 to push the pusher 310, dirt such as leaves that are difficult to scrape off are pushed away from the rainproof roof 2, solving the problem of dirt accumulation causing the rainwater flow rate to slow down. At the same time, through the cooperation of the interceptor 312 and the scraper 306, when the pusher 310 resets, it passes through the interceptor 312 to remove the dirt, making it easier for the next round of work, thereby improving the drainage efficiency of the rainproof roof 2.

[0023] In this embodiment, during heavy rain, the rain sensor 7 detects rainwater and sends an electrical signal to control the waterproof motor 6 to start. This motor drives the reciprocating screw 301 to rotate. The reciprocating screw 301 causes the threaded block 302 to move closer to the rainproof top 2. When the reciprocating screw 301 causes the threaded block 302 to move closer to the rainproof top 2, the threaded block 302 presses against the scraper 306. When the threaded block 302 presses against the scraper 306, the scraper 306 moves downward. When compressed and moved downwards, the scraper 306 compresses the limiting rod 304 and moves downwards. When the limiting rod 304 is compressed and moves downwards to the bottom, the scraper 306 compresses the large slider 303. When the large slider 303 is compressed, it causes the scraper 306 to slide downwards, scraping the rainwater from the rainproof roof 2 downwards. Conversely, when the reciprocating screw 301 drives the threaded block 302 to move obliquely upwards, the scraper 306 loses the compression from the threaded block 302. When the scraper 306 loses the compression from the threaded block 302, the compression spring... Spring 305 pushes scraper 306 upward. When scraper 306 moves upward, it drives limit rod 304 upward. When limit rod 304 moves upward, large slider 303 loses its compression. When large slider 303 is no longer compressed, long spring 311 pushes large slider 303 to drive scraper 306 upward, ensuring that scraper 306 does not contact rainproof top 2 during reset. When scraper 306 moves downward, it drives small slider 307 downward. When small slider 307 moves downward, it drives connecting rod 3... When the connecting rod 308 moves downward, it drives the pusher 310 to move downward, pushing away some flat debris such as leaves that are difficult to scrape off. When the scraper 306 moves upward, the short spring 309 presses the connecting rod 308, causing the connecting rod 308 to return to its original position. When the connecting rod 308 moves upward, it drives the pusher 310 to move synchronously, causing the pusher 310 to be misaligned with the interceptor 312. When the pusher 310 and the interceptor 312 are misaligned, the interceptor 312 squeezes and scrapes off the leaves driven by the pusher 310.

[0024] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a protective device 4 for covering the equipment during heavy rain is provided on the lower side of the rainproof roof 2. The protective device 4 includes a sliding plate 401, a sleeve plate 402, a strong spring 403, a water collection box 404, a water storage box 405, a drain hole 406, a bump and recess 407, a sliding rod 408, a pressure block 409, a return spring 410, and a striking block 411. The lower end of the rainproof roof 2 is fixedly connected to the upper end of the sleeve plate 402, the inner wall of the sleeve plate 402 is slidably connected to the outer wall of the sliding plate 401, the upper end of the sliding plate 401 is fixedly connected to the lower end of the strong spring 403, and the upper end of the strong spring 403 is fixedly connected to the lower end of the rainproof roof 2. The outer end of the rainproof roof 2 is fixedly connected to the inner end of the water collection box 404, and the outer end of the sliding plate 401 is fixedly connected to the inner end of the water storage box 405. A drain hole 406 is provided on the water storage box 405 to increase the amount of rainwater in the water storage box 405. Pulling the sliding plate 401 covers the side of the meter body 1 to prevent rainwater from seeping horizontally. The front end of the large slider 303 is fixedly connected to the rear end of the bump block 407. The inner wall of the rainproof top 2 is slidably connected to the outer wall of the sliding rod 408. The outer wall of the sliding rod 408 is fixedly connected to the inner wall of the pressure block 409. The upper end of the sliding rod 408 is fixedly connected to one end of the return spring 410, and the other end of the return spring 410 is fixedly connected to the lower side of the rainproof top 2. The outer wall of the sliding rod 408 is fixedly connected to the inner wall of the striking block 411. By moving the bump block 407 and colliding with the pressure block 409, the striking block 411 strikes the rainproof top 2 through the cooperation of the sliding rod 408 and the return spring 410, thereby breaking the surface tension of the rainwater.

[0025] When rainwater is blown down, it is collected in the water storage box 405 through the water collection box 404. At this time, through the cooperation of the sliding plate 401 and the strong spring 403, when the rainwater collection speed is greater than the drainage speed, the sliding plate 401 is lowered to protect the side of the housing 8. This solves the problem of rainwater seeping into the meter body 1 through the heat dissipation holes during heavy rain and improves the service life of the equipment. As the bump block 407 moves and collides with the pressure block 409, the sliding rod 408 and the return spring 410 work together to make the striking block 411 strike the rainproof roof 2, which solves the problem that rainwater is slowed down due to tension in places that the scraper 306 cannot reach, thereby further increasing the speed at which rainwater leaves the rainproof roof 2.

[0026] A defogging device 5 is provided on the upper side of the housing 8 to prevent excessive fogging from affecting the reading of the meter body 1. The defogging device 5 includes an air chamber 501, an air pipe 502, a filter sponge 503, an L-plate 504, a flexible switch 505, a controller 506, and a heating plate 507. The air chamber 501 is detachably installed on the inner side of the sleeve 402. The inner wall of the air chamber 501 is fixedly connected to the outer wall of the air pipe 502, and the housing 8, air pipe 502, air chamber 501, and sleeve 402 are interconnected. The inner wall of the air chamber 501 is fixedly connected to the outer wall of the filter sponge 503, and the filter sponge 504... 3 is made of wood pulp cotton. When the slide plate 401 slides in, it causes the air inside the sleeve to flow. The air passes through the air chamber 501 and the moisture is absorbed by the filter sponge 503. Finally, the air pipe 502 inputs dry air into the meter body 1. The lower side of the sleeve plate 402 is fixedly connected to the upper end of the L plate 504. The lower side of the L plate 504 is slidably connected to the elastic switch 505. The elastic switch 505 is electrically connected to the controller 506. The rear side of the controller 506 is fixedly connected to the front side of the housing 8. The upper end of the air chamber 501 is fixedly connected to the lower end of the heating plate 507. The controller 506 and the heating plate 507 are electrically connected.

[0027] When the wiper device 3 stops wiping rainwater in, the outflow of rainwater in the water storage box 405 is greater than the inflow, and the weight of the water storage box 405 is reduced. At this time, the strong spring 403 pulls the slide plate 401 into the sleeve plate 402, injecting air from the sleeve into the air chamber 501. Through the absorption of moisture by the filter sponge 503, the air pipe 502 finally introduces dry air into the housing 8, which solves the problem that the display of the meter body 1 is not clear due to high humidity, and prevents users from having difficulty reading the reading and affecting their work. Furthermore, the slide plate 401 slides out and moves, colliding with the elastic switch 505. Through the cooperation of the L plate 504 and the controller 506, the heating plate 507 is activated to dry the air chamber 501 and the filter sponge 503, solving the problem of reduced moisture filtration effect during continuous rainy weather, thereby improving the performance.

[0028] In this embodiment, when the scraper blade 306 falls, rainwater is propelled through the water collection box 404 to the water storage box 405. As the rainwater flows into the water storage box 405, it flows out through the drain hole 406. If the rainwater is heavy, the water accumulation rate is greater than the drainage rate, causing the weight of the water storage box 405 to continuously increase. As the weight of the water storage box 405 increases, it compresses the sliding plate 401. When the sliding plate 401 is compressed, it compresses the strong spring. Spring 403: When the sliding plate 401 compresses the strong spring 403, the sliding plate 401 slides out from the inner wall of the sleeve plate 402, covering the side of the housing 8 to prevent excessive rainwater from wetting the meter body 1 from the side. Conversely, when the rain is light or stops, the drainage volume is greater than the water accumulation volume. When the drainage volume is greater than the water accumulation volume, the weight inside the water storage box 405 is reduced. When the water storage box 405 is lighter, the compressive force on the sliding plate 401 is reduced, causing the strong spring 403 to pull the sliding plate 401. Plate 401 resets; when the large slider 303 slides, it causes the large slider 303 to drive the bump block 407 to move. When the bump block 407 moves downward, the protrusion of the bump block 407 collides with the pressure block 409. When the protrusion of the bump block 407 collides with the pressure block 409, the pressure block 409 is squeezed. When the pressure block 409 is squeezed, the pressure block 409 drives the slide rod 408 to move downward. When the slide rod 408 moves downward, it drives the striking block 411 to move downward. Conversely, when the protrusion of the bump 407 passes over the pressure block 409, the pressure block 409 is no longer squeezed and loses its pressure. When the pressure block 409 loses its pressure, the short spring 309 pulls the slide rod 408 to reset. When the slide rod 408 resets, it drives the striking block 411 to move upward and collide with the rainproof roof 2. This is repeated to continuously strike the rainproof roof 2, causing the rainwater in the area that the scraper 306 at the lower end of the rainproof roof 2 cannot reach to fall faster.

[0029] When the slide plate 401 slides into the sleeve, it allows air from the sleeve to enter the air chamber 501. This air then passes through the filter sponge 503, becoming dry, and flows into the air pipe 502. This dry air then flows into the meter body 1, reducing the likelihood of blurring on the meter screen due to condensation. Conversely, when the slide plate 401 slides out of the sleeve 402, it presses the elastic switch 505 on the L-plate 504. When the elastic switch 505 on plate L 504 is activated, it moves and releases an electrical signal to controller 506. When the elastic switch 505 releases an electrical signal to controller 506, controller 506 activates heating plate 507, which heats air chamber 501 to keep filter sponge 503 dry for the next round of work to filter moisture. When the heavy rain stops, slide plate 401 moves upward to reset. At this time, the pressure of slide plate 401 is released, elastic switch 505 resets, and stops releasing electrical signals to controller 506, causing controller 506 to control heating plate 507 to stop heating to prevent energy waste caused by continuous heating.
