Description

Technical Field

[0001] This invention belongs to the technical field of electricity metering boxes, specifically relating to an intelligent dust-removing electricity metering box. Background Technology

[0002] Existing electricity metering boxes are mostly installed outdoors or in distribution rooms. After long-term operation, a large amount of dust easily accumulates inside the box, covering the current transformer, wiring terminals and the surface of the meter. This not only affects heat dissipation efficiency and accelerates insulation aging, but may also cause creepage or short circuit faults due to dust accumulation and moisture, reducing metering accuracy and equipment reliability. Traditional metering boxes rely only on natural ventilation or simple filters for dust prevention and lack active dust removal function, making it impossible to remove internal dust in a timely manner. There is an urgent need for an electricity metering box with intelligent dust removal function.

[0003] Patent CN121055167B discloses an intelligent dust-removing electricity metering box, relating to the field of electricity metering box technology. The box includes a main body with two protective doors on its side. Inside the main body are a first chamber and a second chamber. The first chamber houses an electricity meter and a miniature circuit breaker, while the second chamber houses a plastic-cased circuit breaker. A cooling fan is fixed to the side of the main body, and a controller is fixed to the side of the main body away from the cooling fan. This patent uses a wind speed sensor to intelligently monitor the airflow through the air inlet pipe in real time. When the airflow is insufficient to meet the cooling requirements, a drive motor is activated, causing the cleaning brush to reciprocate and automatically clean the dust adhering to the dust filter, reducing dust on the filter, ensuring its permeability, and effectively preventing the impact of dust filter blockage on the overall cooling of the metering box.

[0004] The above-mentioned device also has the following problems: During the use of the above-mentioned device to remove dust from the dustproof net, if it is raining heavily, the dust on the surface of the dustproof net will mix with the rainwater, causing the dust to adhere to the dustproof net. At this time, it is easy to cause incomplete dust removal, which will affect the dust removal effect and efficiency of the device in the future. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent dust-removing power metering box to solve the problem of difficulty in removing dust when dust and rainwater adhere to the dustproof net at the same time.

[0006] To achieve the above objectives, the present invention provides an intelligent dust-removing electricity metering box, comprising: a metering box body; an electric telescopic rod fixedly connected to the inner wall of the metering box body; an elastic telescopic rod fixedly connected to the telescopic end of the electric telescopic rod; a top plate fixedly connected to the telescopic end of the elastic telescopic rod; a scraping mechanism provided on the left side of the metering box body; a sealing mechanism provided on the left side of the top plate; a ventilation plate fixedly connected to the inner wall of the top plate; an installation rod fixedly connected to the top of the metering box body; a slanted scraper fixedly connected to the inner wall of the installation rod; a connector fixedly connected to the inner wall of the top plate; an exhaust plate fixedly connected to the inner wall of the connector; a fixing frame fixedly connected to the front of the connector; a heating rod fixedly connected to the inner wall of the fixing frame; a fan fixedly connected to the inner wall of the metering box body; and a corrugated pipe fixedly connected to the fan. The slanted scraper can scrape away dust from the surface of the ventilation plate as it moves downwards, cleaning dust from multiple ventilation plates on the metering box body, ensuring ventilation and improving the dust removal effect of the device.

[0007] According to another advantageous design of the present invention, the ventilation plate is in contact with the inclined scraper, and the inclined scraper is used to scrape and clean the dust on the surface of the ventilation plate. The inclined scraper is located on the movement trajectory of the top plate, and the dust on the surface of the ventilation plate after drying can be pushed and scraped off in time by the inclined scraper, which can improve the dust removal effect and quality of the device.

[0008] According to another advantageous design of the invention, the corrugated pipe is connected to the exhaust plate, the exhaust opening of the exhaust plate faces the ventilation plate one, and the exhaust plate is used to remove dust from the ventilation plate one. The ventilation plate one will be reset, at which time the heating rod will be started, and the fan will also be started. The fan can draw the hot gas in the metering box body into the exhaust plate through the corrugated pipe and discharge the hot gas to the ventilation plate one.

[0009] According to another advantageous design of the present invention, the scraping mechanism includes a mounting frame fixedly connected to the left side of the metering box body. A motor is fixedly connected to the front of the mounting frame. A reciprocating lead screw is rotatably connected to the inner wall of the mounting frame. A moving rod is movably connected to the circumferential surface of the reciprocating lead screw. A slider is fixedly connected to the right side of the moving rod. A vertical rod is fixedly connected to the top of the moving rod. A push plate is fixedly connected to the right side of the vertical rod. A second ventilation plate is fixedly connected to the inner wall of the top plate. The push plate can scrape off the dust on the surface of the second ventilation plate, ensuring the ventilation stability of the device and enabling the device to simultaneously perform dust removal treatment on multiple ventilation areas.

[0010] According to another advantageous design of the present invention, the scraping mechanism further includes a fixed top frame, which is fixedly connected to the inner wall of the metering box body. An elastic telescopic rod II is fixedly connected to the inner wall of the top plate. A sealing plate is fixedly connected to the telescopic end of the elastic telescopic rod II. A buffer block is fixedly connected to the bottom of the sealing plate. A laser rangefinder is fixedly connected to the left side of the buffer block. The laser rangefinder can detect the distance between itself and the ventilation plate II and compare the distance with the pre-calibrated numerical control data. At this time, it can detect that the surface of the ventilation plate II is covered with a lot of dust, which affects the heat dissipation and ventilation of the device. This provides a guarantee for subsequent manual cleaning or intelligent dust removal of the ventilation plate II by pushing the plate.

[0011] According to another advantageous design of the present invention, the buffer block is located on the movement trajectory of the sealing plate, and the fixed top frame is used to push the buffer block to move in the opposite direction. The sealing plate is in contact with the top plate and is used to seal the top plate. The slider is slidably connected to the left side of the metering box body and is used to provide movement guidance and limit for the moving rod. The push plate is located on the movement trajectory of the second ventilation plate. The movement of the second elastic telescopic rod will drive the sealing plate to move, and the sealing plate will drive the buffer block to move. During the movement, the buffer block will drive the laser ranging sensor to move.

[0012] According to another advantageous design of the present invention, the sealing mechanism includes a horizontal plate fixedly connected to the left side of the push plate, a sliding column slidably connected to the inner wall of the horizontal plate, a roller rotatably connected to the inner wall of the sliding column, a sponge block fixedly connected to the right side of the sliding column, and a guide rod fixedly connected to the top of the mounting bracket. During the movement of the sponge block on the second surface of the ventilation plate, the sponge block can wipe away rainwater and dust from the second surface of the ventilation plate, thereby improving the dust removal effect of the device and preventing rainwater and dust from clogging the ventilation area.

[0013] According to another advantageous design of the present invention, the sealing mechanism further includes a slot frame, which is fixedly connected to the left side of the top plate. A sliding door is slidably connected to the inner wall of the slot frame, and a limit post is slidably connected to the inner wall of the slot frame. The sliding door can seal and close the ventilation plate two after it is moved, so as to prevent dust and other debris from adhering to the surface of the ventilation plate two and causing subsequent dust removal difficulties.

[0014] According to another advantageous design of the present invention, the guide rod is located on the movement trajectory of the roller and is used to push the roller to move. The limiting post is in contact with the sliding door and is used to limit the sliding door. A return spring is connected between the sliding post and the cross plate. The operator can manually pull the limiting post to move it. After the limiting post moves, it will release the limitation on the sliding door.

[0015] The beneficial effects of this invention are: 1. This intelligent dust-removing electricity metering box, through the coordinated movement of the metering box body, electric telescopic rod, elastic telescopic rod 1, top plate, scraping mechanism, sealing mechanism, ventilation plate 1, mounting rod, inclined scraper, connecting parts, exhaust plate, fixing frame, heating rod, fan, and corrugated pipe, enables the inclined scraper to scrape away dust on the surface of the ventilation plate 1 as it moves downward. This cleans the dust from multiple ventilation plates on the metering box body, ensuring the ventilation status of the device and improving its dust removal effect. The dried dust on the surface of the ventilation plate 1 can be promptly pushed and scraped away by the inclined scraper, thus improving the dust removal effect and quality of the device.

[0016] 2. This intelligent dust-removing power metering box, through the coordinated movement of the mounting frame, motor, reciprocating screw, moving rod, slider, vertical rod, push plate, fixed top frame, elastic telescopic rod II, sealing plate, buffer block, laser rangefinder, and ventilation plate II, enables the push plate to scrape dust off the surface of ventilation plate II, ensuring the ventilation stability of the device. It allows the device to simultaneously remove dust from multiple ventilation areas. The laser rangefinder can detect the distance between itself and ventilation plate II and compare the distance with pre-calibrated numerical control data. This allows it to detect when ventilation plate II is covered with excessive dust, which could affect the device's heat dissipation and ventilation. This provides assurance for subsequent manual cleaning by staff or intelligent dust removal by the push plate.

[0017] 3. This intelligent dust-removing power metering box, through the coordinated movement of the horizontal plate, sliding column, roller, sponge block, guide rod, slot frame, sliding door, and limit column, allows the sponge block to wipe away rainwater and dust from the surface of the second ventilation plate during its movement. This improves the dust removal effect of the device and prevents rainwater and dust from clogging the ventilation area. The sliding door can seal and close the second ventilation plate after movement, preventing dust and other debris from adhering to the surface of the second ventilation plate and causing difficulties in subsequent dust removal.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-10 As shown, one embodiment of the present invention is an intelligent dust-removing power metering box, comprising: a metering box body 1, an electric telescopic rod 2 fixedly connected to the inner wall of the metering box body 1, an elastic telescopic rod 3 fixedly connected to the telescopic end of the electric telescopic rod 2, a top plate 4 fixedly connected to the telescopic end of the elastic telescopic rod 3, a scraping mechanism 5 provided on the left side of the metering box body 1, a sealing mechanism 6 provided on the left side of the top plate 4, a ventilation plate 7 fixedly connected to the inner wall of the top plate 4, an installation rod 8 fixedly connected to the top of the metering box body 1, an inclined scraper 9 fixedly connected to the inner wall of the installation rod 8, a connector 10 fixedly connected to the inner wall of the top plate 4, an exhaust plate 11 fixedly connected to the inner wall of the connector 10, a fixing frame 12 fixedly connected to the front of the connector 10, a heating rod 13 fixedly connected to the inner wall of the fixing frame 12, a fan 14 fixedly connected to the inner wall of the metering box body 1, and a corrugated pipe 15 fixedly connected to the fan 14. When the device is used for a long time, dust will accumulate on the surface of the ventilation plate 7 on the top plate 4. In order to prevent the dust from affecting the ventilation of the ventilation plate 7, the electric telescopic rod 2 will be activated by the electrical signal released by the external controller. The telescopic end of the electric telescopic rod 2 will drive the elastic telescopic rod 3 to move downward. The downward movement of the elastic telescopic rod 3 will simultaneously drive the top plate 4 to move downward. During the downward movement of the top plate 4, the ventilation plate 7 will move downward. During the downward movement of the ventilation plate 7, the ventilation plate 7 will come into contact with the inclined scraper 9. At this time, the inclined scraper 9 can scrape off the dust on the surface of the ventilation plate 7 as it moves downward. This can clean the dust from the multiple ventilation plates 7 on the metering box body 1, ensure the ventilation of the device, and improve the dust removal effect of the device. Ventilation plate 7 contacts the inclined scraper 9, and the inclined scraper 9 is used to scrape and clean the dust on the surface of ventilation plate 7. The inclined scraper 9 is located on the movement trajectory of the top plate 4. The corrugated pipe 15 is connected to the exhaust plate 11. The exhaust opening of the exhaust plate 11 faces the ventilation plate 7, and the exhaust plate 11 is used to remove gas dust from the ventilation plate 7. When the device is used in humid, rainy weather, some dust will adhere to the surface of the ventilation plate 7 along with rainwater, forming a layer of mud-like residue. After the inclined scraper 9 completes the initial dust removal of the ventilation plate 7, the ventilation plate 7 will reset. At this time, the heating rod 13 will start, and the fan 14 will also start. The fan 14 can draw the hot gas from the metering box 1 through the corrugated pipe 15 into the exhaust plate 11 and discharge the hot gas toward the ventilation plate 7. During the discharge process, the hot gas can simultaneously carry the hot gas emitted by the heating rod 13, and the gas can come into contact with the ventilation plate 7. At this time, the hot gas can remove the loose dust on the ventilation plate 7. Dust and debris are blown away, and the hot gas dries the mud-like dust after contacting the ventilation plate 7. After running for a period of time, the top plate 4 will be moved downward again by the elastic telescopic rod 3. The movement of the top plate 4 will cause the connecting piece 10 to move synchronously. The movement of the connecting piece 10 will cause the exhaust plate 11 to move. At the same time, the connecting piece 10 will also cause the fixing frame 12 to move. The movement of the fixing frame 12 will cause the heating rod 13 to move. At the same time, the top plate 4 will also cause the ventilation plate 7 to move downward again. At this time, the dust on the surface of the ventilation plate 7 can be pushed and scraped off by the inclined scraper 9 in time, which can improve the dust removal effect and quality of the device. Overall working principle: The inclined scraper 9 can scrape off the dust on the surface of the ventilation plate 7 as it moves downward, and can clean the dust from the multiple ventilation plates 7 on the metering box body 1, ensuring the ventilation status of the device and improving the dust removal effect. The dust on the surface of the ventilation plate 7 after it has dried can be pushed and scraped off by the inclined scraper 9 in time, which can improve the dust removal effect and quality of the device.

[0022] like Figures 1-10 As shown, based on the above embodiment, the scraping mechanism 5 includes a mounting frame 501, which is fixedly connected to the left side of the metering box body 1. A motor 502 is fixedly connected to the front of the mounting frame 501. A reciprocating screw 503 is rotatably connected to the inner wall of the mounting frame 501. A moving rod 504 is movably connected to the circumferential surface of the reciprocating screw 503. A slider 505 is fixedly connected to the right side of the moving rod 504. A vertical rod 506 is fixedly connected to the top of the moving rod 504. A push plate 507 is fixedly connected to the right side of the vertical rod 506. A ventilation plate 513 is fixedly connected to the inner wall of the top plate 4. When the device is used in heavy rain, to prevent water from entering the metering box 1, the top plate 4 needs to move downwards, causing the ventilation plate 7 to move and reduce ventilation. During this downward movement, the top plate 4 will move the ventilation plate 513. After moving a certain distance, the ventilation plate 513 will be positioned on the trajectory of the push plate 507. Then, the motor 502 will be started via an electrical signal from an external control terminal. The movement of the motor 502 will cause the reciprocating screw 503 to rotate. During this rotation, the reciprocating screw 503 will cause the moving rod 504 to move, which in turn will move the slider 50. 5. During the movement, the slider 505 always slides on the left side of the metering box body 1. The slider 505 can provide movement guidance for the moving rod 504. The slider 505 causes the moving rod 504 to move laterally only through the reciprocating groove opened on the surface of the reciprocating screw 503 during the rotation of the reciprocating screw 503. During the lateral movement of the moving rod 504, the moving rod 504 will drive the vertical rod 506 to move. The movement of the vertical rod 506 will drive the push plate 507 to move. During the movement of the push plate 507, the push plate 507 can scrape the dust on the surface of the ventilation plate 513, ensuring the ventilation stability of the device and enabling the device to perform dust removal treatment on multiple ventilation areas at the same time. The scraping mechanism 5 also includes a fixed top frame 508, which is fixedly connected to the inner wall of the metering box body 1. An elastic telescopic rod 509 is fixedly connected to the inner wall of the top plate 4. A sealing plate 510 is fixedly connected to the telescopic end of the elastic telescopic rod 509. A buffer block 511 is fixedly connected to the bottom of the sealing plate 510. A laser range sensor 512 is fixedly connected to the left side of the buffer block 511. The buffer block 511 is located on the movement trajectory of the sealing plate 510, and the fixed top frame 508 is used to push the buffer block 511 to move in the opposite direction. The sealing plate 510 contacts the top plate 4 and is used to seal the top plate 4. A slider 505 is slidably connected to the left side of the metering box body 1 and is used to provide movement guide limit for the moving rod 504. The push plate 507 is located on the movement trajectory of the ventilation plate 513. When the device is in use, as the top plate 4 moves downward, the movement of the top plate 4 causes the elastic telescopic rod 509 to move, which in turn causes the sealing plate 510 to move. The sealing plate 510 then moves the buffer block 511, which in turn moves the laser rangefinder 512. After moving downward a certain distance, the buffer block 511 comes into contact with the fixed top frame 508. At this point, the fixed top frame 508 pushes the buffer block 511 in the opposite direction, causing the buffer block 511 to rise as the top plate 4 moves downward. This rise of the buffer block 511 then causes the sealing plate 510 to move further downward. As the buffer block 511 rises, it will also cause the laser range sensor 512 to rise. At this time, the laser range sensor 512 will be activated and can release multiple laser beams. It can judge the degree of dust coverage by the change of reflected light intensity. If the surface of the ventilation plate 513 is blocked by dust or other debris, the laser range sensor 512 can detect the distance between itself and the ventilation plate 513 and compare the distance with the pre-adjusted CNC data. At this time, it can detect that the surface of the ventilation plate 513 is covered with a lot of dust, which will affect the heat dissipation and ventilation of the device. This provides a guarantee for subsequent manual cleaning by staff or intelligent dust removal of the ventilation plate 513 by the push plate 507. The sealing mechanism 6 includes a horizontal plate 601, which is fixedly connected to the left side of the push plate 507. A sliding column 602 is slidably connected to the inner wall of the horizontal plate 601. A roller 603 is rotatably connected to the inner wall of the sliding column 602. A sponge block 604 is fixedly connected to the right side of the sliding column 602. A guide rod 605 is fixedly connected to the top of the mounting bracket 501. When the device is in use, the vertical rod 506 moves, which in turn moves the horizontal plate 601. The horizontal plate 601 moves, which in turn moves the sliding column 602. The sliding column 602 moves, which in turn moves the roller 603. At the same time, the sponge block 604 moves. When the roller 603 has moved a certain distance, it will come into contact with the inclined surface of the guide rod 605. At this time, the inclined surface of the guide rod 605 will press and push the roller in the opposite direction as the roller 603 moves. The roller 603 moves, which drives the sliding column 602 to move. The sliding column 602 moves, which drives the sponge block 604 to move. At this time, the sponge block 604 will contact the ventilation plate 2 513 and move on the surface of the ventilation plate 2 513. During the process of moving on the surface of the ventilation plate 2 513, the sponge block 604 can wipe away rainwater and dust on the surface of the ventilation plate 2 513, which can improve the dust removal effect of the device and prevent rainwater and dust from mixing and blocking the ventilation area. The sealing mechanism 6 also includes a slot frame 606, which is fixedly connected to the left side of the top plate 4. A sliding door 607 is slidably connected to the inner wall of the slot frame 606. A limit post 608 is slidably connected to the inner wall of the slot frame 606. A guide rod 605 is located on the movement trajectory of the roller 603 and is used to push the roller 603 to move. The limit post 608 contacts the sliding door 607 and is used to limit the sliding door 607. A return spring is connected between the sliding post 602 and the horizontal plate 601. When the device is used in heavy rain, in order to prevent rainwater or other substances from entering the top plate 4 with the strong wind, the staff can manually pull the limiting column 608 to move it. After the limiting column 608 moves, it will release the limiting of the sliding door 607. At this time, the sliding door 607 will slide down the inner wall of the trough frame 606 by gravity. After the sliding door 607 moves, it can seal and close the ventilation plate 2 513, preventing dust and other debris from adhering to the surface of the ventilation plate 2 513 and causing difficulties in subsequent dust removal.

[0023] Overall working principle: The push plate 507 can scrape away dust from the surface of the second ventilation plate 513, ensuring the ventilation stability of the device and enabling the device to simultaneously remove dust from multiple ventilation areas. The laser rangefinder 512 can detect the distance between itself and the second ventilation plate 513 and compare the distance with the pre-calibrated CNC data. At this time, it can detect that the surface of the second ventilation plate 513 is covered with a lot of dust, which affects the heat dissipation and ventilation of the device. This provides a guarantee for subsequent manual cleaning by staff or intelligent dust removal of the second ventilation plate 513 by the push plate 507. During the movement of the sponge block 604 on the surface of the second ventilation plate 513, the sponge block 604 can wipe away rainwater and dust on the surface of the second ventilation plate 513, which can improve the dust removal effect of the device and prevent rainwater and dust from mixing and blocking the ventilation area. The sliding door 607 can seal and close the second ventilation plate 513 after it moves, preventing dust and other debris from adhering to the surface of the second ventilation plate 513 and causing difficulties in subsequent dust removal.
