Description

Technical Field

[0001] The present invention relates to the technical field of electric meters, and specifically to an electric meter structure with moisture-proof and anti-theft functions. Background Art

[0002] An electric meter is an instrument used to measure electric energy, also known as a kilowatt-hour meter, a watt-hour meter, an electric energy meter, or a kilowatt-hour meter, which refers to an instrument for measuring various electrical quantities.

[0003] After retrieval, it is found that the prior art publication number is CN114062747B, which discloses an electric meter structure with moisture-proof and anti-theft functions, including an anti-electric leakage device for an electric meter. The anti-electric leakage device for an electric meter includes a housing, including an induction unit; a limiting unit; an insulating unit; the induction unit is arranged on the outer side of the housing, the limiting unit is arranged on the upper side of the housing to limit the insulating unit, and when the housing leaks electricity, the induction unit triggers the limiting unit to make the insulating unit wrap the housing.

[0004] The above-mentioned existing moisture-proof electric meter is set in a sealed state, and a desiccant is provided inside. However, the joints of the electric meter are still connected to the air. After the wires at the joints are weathered for a long time, the wires and the joints of the electric meter will rust and become brittle, resulting in wire detachment or short circuit. Therefore, based on the above retrieval and combined with the existing problems, an electric meter structure with moisture-proof and anti-theft functions is provided. Summary of the Invention

[0005] The purpose of the present invention is to provide an electric meter structure with moisture-proof and anti-theft functions to solve the problem that the wires at the joints will rust and become brittle after being weathered for a long time, resulting in wire detachment or short circuit as proposed in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An electric meter structure with moisture-proof and anti-theft functions comprises an electric meter box, an electric recorder is slidably mounted on the inner wall of the electric meter box, an electric input connector is slidably mounted on the input end of the electric meter box, an electric connection connector is fixedly mounted on one end of the electric meter box away from the electric input connector, moisture-proof mechanisms are arranged at the joints at both ends of the electric wire connected to the electric recorder to prevent the connection from being damp and rusted, an alarm mechanism for sounding an alarm is arranged on the inner wall of the electric meter box, a detection mechanism for illegal power-off is arranged on the inner wall of the electric meter box close to the alarm mechanism, and a control mechanism for controlling the alarm mechanism to be turned on and off is arranged between the detection mechanism and the alarm mechanism. Specifically, the material in the moisture-proof mechanism removes moisture and rusts the connection of the electric meter, a separate power supply is arranged inside the alarm mechanism, so that the alarm can still be sounded in the case of power failure, a wire cutting triggering alarm mechanism device is arranged in the detection mechanism, so that after the thief steals and cuts the wire, the alarm mechanism sounds an alarm, and the control mechanism is a simple operation but has a trap mechanism, so that the real user can use it conveniently, and the thief will be confused by the trap to trigger the alarm mechanism, thereby protecting the electric meter from being stolen.

[0008] Further, the moisture-proof mechanism includes a moisture-proof cylinder, and the moisture-proof cylinder is fixedly installed on the upper ends of the power-in connector and the power-on connector, a moisture-proof cover is rotatably installed on the upper end of the moisture-proof cylinder, a rotating buckle is rotatably installed on the upper end of the moisture-proof cover, a drying bag is fixedly installed on the lower end of the rotating buckle, and a bag-breaking piece is fixedly installed on the rotating buckle near the lower end of the drying bag, and arc grooves are provided on the side ends of the moisture-proof cylinder and the moisture-proof cover, and a rubber ring is fixedly installed in the arc groove. Specifically, when the recorder is connected to the connector, the rotating buckle is fastened and twisted, so that the rotating buckle drives the drying bag to start rotating, and the bag-breaking piece cuts the drying bag, so that the calcium chloride dust particles stored in the drying bag wrap the connector, thereby protecting the connector from moisture and rust. At the same time, the calcium chloride dust particles absorb water vapor and are converted into a gel to wrap the connector, isolating the connector from air, which can achieve a better moisture-proof effect.

[0009] Furthermore, the alarm mechanism includes a battery, a charger is fixedly installed at the input end of the battery, a charging wire is fixedly installed at the input end of the charger, and the charging wire is fixedly installed at the lower end of the power-on connector, an output wire is fixedly installed at the output end of the battery, a power-on block is fixedly installed at the end of the output wire away from the battery, a brush block is fixedly installed on the inner wall of the meter box close to the power-on block, a connecting wire is fixedly installed at the end of the brush block away from the power-on block, and an alarm is fixedly installed at the end of the connecting wire away from the brush block. Specifically, when the gap between the power-on block and the brush block is connected by the energized metal in the detection mechanism, the battery provides power for the alarm, causing the alarm to start to sound an alarm to remind people that the meter has been stolen, thereby avoiding the meter from being stolen.

[0010] Furthermore, the detection mechanism includes a live wire, and the live wire is fixedly installed at the input end of the relay. The end of the live wire away from the relay is fixedly installed with a threaded coil, and the threaded coil is fixedly installed at the side end of the power input connector. A connecting telescopic rod is fixedly installed on the inner wall of the meter box close to the threaded coil, and an electromagnetic rod is fixedly installed at the upper end of the connecting telescopic rod. Specifically, when the power passes through the threaded coil, the threaded coil generates an electromagnetic field, and the electromagnetic field generated by the threaded coil provides a lifting force for the electromagnetic rod, causing the electromagnetic rod to start moving. When the power is cut off, the electromagnetic rod moves downward under the action of gravity, thereby detecting whether the wire is energized.

[0011] Furthermore, an insulating sheet is fixedly installed at the upper end of the electromagnetic rod, a power-on sheet is fixedly installed at the upper end of the insulating sheet, a metal sheet is slidably installed at the side end of the power-on sheet, a disconnecting sheet is fixedly installed at the lower end of the metal sheet, and the disconnecting sheet is slidably installed at the side end of the power-on block close to the brush block. Specifically, when a power outage occurs, the electromagnetic rod drives the power-on sheet to move downward. The power-on sheet contacts the power-on block, but the disconnecting sheet still separates the power-on block from the brush block, preventing the alarm from being triggered when the power is cut off or the circuit breaker is turned off.

[0012] Furthermore, a pushing spring is fixedly installed between the meter box and the disconnecting sheet. A control rope is fixedly installed at the end of the disconnecting sheet close to the pushing spring, and the other end of the control rope is fixedly installed at the side end of the power input connector. A control block is slidably installed on the inner wall of the meter box close to the disconnecting sheet. Specifically, when the wire is cut, the power input connector is no longer pulled. The pushing spring pushes the disconnecting sheet, causing the metal sheet to contact the brush block. At the same time, the wire is cut, the threaded coil no longer has current, the electromagnetic rod moves, the power-on sheet contacts the power-on block, the brush block and the power-on block are energized, and the alarm is energized to sound an alarm.

[0013] Furthermore, the control mechanism includes a control rod, and the control rod is fixedly installed at the side end of the relay close to the control block. A data rod is fixedly installed at the output end of the relay. A display is provided at the end of the data rod away from the relay, and the display is slidably attached to the surface of the meter box. A sliding groove is opened at the side end of the meter box close to the data rod. Specifically, when it is necessary to disassemble the meter to prevent the alarm on the meter from sounding, the display is pushed, causing the data rod to drive the relay to start moving, the control rod to push the control block to move, and the control block to push the disconnecting sheet to contact the brush block, so that the alarm will not be triggered when the circuit is disassembled.

[0014] Further, a false keyhole is fixedly installed on the side end of the meter box close to the control block. A crowbar is rotatably arranged in the false keyhole, and a linkage rod is slidably installed at one end of the crowbar away from the false keyhole. One end of the linkage rod away from the crowbar is rotatably installed with a power-on rod, and the power-on rod is slidably arranged at the upper end of the inner wall of the meter box. An elastic cord causes the crowbar to tilt upwards under normal circumstances, and the power-on rod does not contact the brush block. Specifically, when a thief places a key or other item in the false keyhole, the crowbar is pushed open, causing the crowbar to start rotating. The linkage rod drives the power-on rod to slide, and the power-on rod connects the power-on block and the brush block, energizing the alarm. Thus, an obvious trap is used to lure the thief into triggering the alarm and prevent the meter from being violently removed.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By tightening the rotating buckle and turning the rotating buckle, the rotating buckle drives the drying bag to start rotating, and the bag-breaking piece cuts the drying bag. The calcium chloride dust particles stored in the drying bag wrap the joint, thereby protecting the joint from moisture and rust. At the same time, after the calcium chloride dust particles absorb water vapor, they are converted into a gel that wraps the joint, isolating the joint from the air and achieving a better moisture-proof effect.

[0017] 2. When the wire is cut, the threaded coil does not generate an electromagnetic field. Under the action of gravity, the electromagnetic rod moves downward, pushing the spring to drive the disconnecting piece to move, connecting the power-on block and the brush block, and causing the alarm to sound, thereby preventing the meter from being stolen.

[0018] 3. When a power outage occurs, the electromagnetic rod drives the power-on piece to move downward. The power-on piece contacts the power-on block, but the disconnecting piece still separates the power-on block and the brush block, preventing the alarm from being triggered when there is a power outage or the circuit breaker is turned off.

[0019] 4. A trap is provided in the control mechanism of the present invention. When a thief places a key or other item in the false keyhole, the crowbar is pushed open, causing the crowbar to start rotating. The linkage rod drives the power-on rod to rotate, connecting the power-on block and the brush block, and energizing the alarm. Thus, an obvious trap is used to lure the thief into triggering the alarm and prevent the meter from being violently removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer toFigures 1 to 9 , an electricity meter structure with moisture-proof and anti-theft functions, including an electricity meter box 1. A relay 101 is slidably installed on the inner wall of the electricity meter box 1. The above relay 101 is a prior art and will not be elaborated here. The relay 101 converts the accessed electric energy into mechanical energy or other forms of signals through the internal measurement mechanism. After processing and calculation, the electricity consumption is displayed in digital or pointer form. An incoming power connector 102 is slidably installed at the input end of the electricity meter box 1. A power-on connector 103 is fixedly installed at one end of the electricity meter box 1 away from the incoming power connector 102. A moisture-proof mechanism 2 for preventing the connection part from getting damp and rusty is provided at the two ends of the wire connected to the relay 101. Specifically, the material in the moisture-proof mechanism 2 dehumidifies and rust-proofs the connection part of the electricity meter. An alarm mechanism 3 for emitting an alarm is provided on the inner wall of the electricity meter box 1. Specifically, a separate power supply is provided inside the alarm mechanism 3 so that an alarm can still be emitted in the case of a power outage. A detection mechanism 4 for detecting illegal power-off is provided on the inner wall of the electricity meter box 1 near the alarm mechanism 3. Specifically, a device for cutting the wire to trigger the alarm mechanism 3 is provided in the detection mechanism 4, so that after a thief steals and cuts the wire, the alarm mechanism 3 emits an alarm. A control mechanism 5 for controlling the opening and closing of the alarm mechanism 3 is provided between the detection mechanism 4 and the alarm mechanism 3. Specifically, the control mechanism 5 is a mechanism with a simple operation but a trap, making it convenient for the real user to use, and the thief will be confused by the trap and trigger the alarm mechanism 3, thereby protecting the electricity meter from being stolen.

[0037] Please refer to Figures 1 to 8, the moisture-proof mechanism 2 includes a moisture-proof cylinder 201, and the moisture-proof cylinder 201 is fixedly installed at the upper ends of the power input connector 102 and the power-on connector 103 respectively. A moisture-proof cover 202 is rotatably installed at the upper end of the moisture-proof cylinder 201, a rotating buckle 203 is rotatably installed at the upper end of the moisture-proof cover 202, a drying bag 204 is fixedly installed at the lower end of the rotating buckle 203. The drying bag 204 is set as a film bag, and calcium chloride dust particles are stored in the drying bag 204. Calcium chloride is a high-efficiency adsorption material, and its main components are calcium chloride and starch gum. Through a chemical method, water molecules react with calcium chloride to absorb moisture from the surrounding environment and turn it into a gel, achieving an adsorption effect. The moisture absorption rate is 8-15 times that of ordinary desiccants. After the calcium chloride dust particles absorb water vapor, they are converted into a gel. A bag-breaking piece 205 is fixedly installed at the lower end of the rotating buckle 203 near the drying bag 204. After the electrical appliance 101 is connected to the connector, tighten the rotating buckle 203 and twist the rotating buckle 203 to drive the drying bag 204 to start rotating. The bag-breaking piece 205 cuts the drying bag 204, so that the calcium chloride dust particles stored in the drying bag 204 wrap the connector, thus protecting the connector from getting damp and rusty. At the same time, after the calcium chloride dust particles absorb water vapor, they are converted into a gel that wraps the connector, isolating the connector from the air and achieving a better moisture-proof effect. A sealing ring 206 is fixedly installed at the upper edge of the moisture-proof cylinder 201. After the moisture-proof cover 202 is rotated and closed, the moisture-proof cover 202 squeezes the sealing ring 206 with the moisture-proof cylinder 201, thereby sealing the power input connector 102 and the power-on connector 103 and preventing the calcium chloride dust particles from floating out of the moisture-proof cylinder 201, playing a sealing role. Arc grooves 207 are provided on the side ends of the moisture-proof cylinder 201 and the moisture-proof cover 202, and rubber rings 208 are fixedly installed in the arc grooves 207. When the moisture-proof cover 202 is rotated and closed after the connector is connected to the wire, the rubber rings 208 provided on the moisture-proof cover 202 and the moisture-proof cylinder 201 squeeze the wire to seal the wire near the moisture-proof cover 202 and the moisture-proof cylinder 201.

[0038] Please refer to Figures 1 to 4, the alarm mechanism 3 includes a storage battery 301. The storage battery 301 is a lead-acid battery in the prior art, made of lead and sulfuric acid, with a positive electrode of lead dioxide and a negative electrode of spongy lead. Its advantages are low price, mature technology, and high reliability. A charger 302 is fixedly installed at the input end of the storage battery 301. The charger 302 is a prior art technology and will not be elaborated here. When the power is turned on, the charger 302 works to charge the storage battery 301. A charging wire 303 is fixedly installed at the input end of the charger 302, and the charging wire 303 is fixedly installed at the lower end of the power connection joint 103. The charging wire 303 connected through the power connection joint 103 charges the storage battery 301, keeping the power of the storage battery 301 in a normal state all the time. An output wire 304 is fixedly installed at the output end of the storage battery 301. One end of the output wire 304 away from the storage battery 301 is fixedly installed with a power connection block 305. A brush block 306 is fixedly installed on the inner wall of the meter box 1 close to the power connection block 305. One end of the brush block 306 away from the power connection block 305 is fixedly installed with a connection wire 307. One end of the connection wire 307 away from the brush block 306 is fixedly installed with an alarm 308. The alarm 308 is a multi-functional alarm in the prior art, with functions such as anti-theft, anti-theft, help seeking, fire prevention, and prevention of poisoning by combustible gases. Once an alarm situation occurs, the host automatically dials the set phone numbers in a loop and emits a voice alarm signal. Specifically, when the gap between the power connection block 305 and the brush block 306 is filled by the structure in the detection mechanism 4, the storage battery 301 provides power for the alarm 308, causing the alarm 308 to start sounding an alarm to remind people that the meter has been stolen, thus avoiding the theft of the meter.

[0039] Please refer to Figures 1 to 5, the detection mechanism 4 includes a current-carrying wire 401, and the current-carrying wire 401 is fixedly installed at the input end of the relay 101. One end of the current-carrying wire 401 away from the relay 101 is fixedly installed with a threaded coil 402. The above-mentioned threaded coil 402 is a threaded coil 402 in the prior art. When current passes through the threaded coil 402, a magnetic field will be generated around it. For a straight current-carrying wire, the magnetic field around it is a concentric circle with each point on the wire as the center. The direction of the magnetic field is judged according to the "right-hand screw rule". And the threaded coil 402 is fixedly installed at the side end of the power input connector 102. A connecting telescopic rod 403 is fixedly installed on the inner wall of the meter box 1 close to the threaded coil 402. The upper end of the connecting telescopic rod 403 is fixedly installed with an electromagnetic rod 404. The connecting telescopic rod 403 prevents the electromagnetic rod 404 from tilting or shifting during the movement process, playing a guiding role. Specifically, when the power supply passes through the threaded coil 402, the threaded coil 402 generates an electromagnetic field. When the electromagnetic rod 404 is in the magnetic field generated by the threaded coil 402 and there is current passing through the electromagnetic rod 404, it will be affected by the magnetic field force. For the force on a straight current-carrying wire in a magnetic field, the left-hand rule is usually used to judge: stretch out the left hand, let the magnetic induction line pass through the palm, the four fingers point to the current direction, and the direction pointed by the thumb is the direction of the Ampere force received by the wire. When there are multiple current elements on the electromagnetic rod 404, each current element will be affected by the Ampere force. The resultant force of these Ampere forces will cause the electromagnetic rod 404 to move, so that the electromagnetic field generated by the threaded coil 402 provides a lifting force for the electromagnetic rod 404. The electromagnetic rod 404 starts to move. When the power is cut off, the electromagnetic rod 404 moves downward under the action of gravity, thereby detecting whether the wire is energized.

[0040] Please refer to Figures 1 to 5 , the upper end of the electromagnetic rod 404 is fixedly installed with an insulating sheet 405, the upper end of the insulating sheet 405 is fixedly installed with a power-on sheet 406, and the power-on sheet 406 is slidably attached to the side end of the brush block 306. A metal sheet 407 is slidably installed at the side end of the power-on sheet 406. The lower end of the metal sheet 407 is fixedly installed with a disconnecting sheet 408, and the disconnecting sheet 408 is slidably installed at the side end of the power-on block 305 close to the brush block 306. Specifically, when a power outage occurs, the electromagnetic rod 404 drives the power-on sheet 406 to move downward. The power-on sheet 406 contacts the power-on block 305, but the disconnecting sheet 408 still separates the power-on block 305 from the brush block 306, preventing the alarm from being triggered when the power is cut off or the circuit breaker is turned off.

[0041] Please refer to Figures 1 to 5, a push spring 409 is fixedly installed between the meter box 1 and the disconnecting piece 408. One end of the disconnecting piece 408 close to the push spring 409 is fixedly installed with a control rope 410, and the other end of the control rope 410 is fixedly installed on the side end of the incoming power connector 102. When the incoming power connector 102 connects the wire, pull the incoming power connector 102, cut the wire to a suitable length and connect it to the incoming power connector 102. After the wire is fixed, restrict the incoming power connector 102 and limit the incoming power connector 102 at the pulled position. The control rope 410 pulls the disconnecting piece 408 to move, compresses the push spring 409, and straightens the wire. Thus, when the wire is cut, the push spring 409 pushes the disconnecting piece 408 to move. A control block 411 is slidably installed on the inner wall of the meter box 1 close to the disconnecting piece 408 (for details, please refer to Figure 2 ). Specifically, when the wire is cut, the incoming power connector 102 is no longer pulled. The push spring 409 pushes the disconnecting piece 408, so that the metal piece 407 contacts the brush block 306. At the same time, the wire is cut, the threaded coil 402 is no longer energized, the electromagnetic rod 404 moves, the energizing piece 406 contacts the energizing block 305, so that the brush block 306 and the energizing block 305 are energized, and the alarm 308 is energized to give an alarm.

[0042] Please refer to Figures 1 to 4 , the control mechanism 5 includes a control rod 501, and the control rod 501 is fixedly installed on the side end of the relay 101 close to the control block 411. The output end of the relay 101 is fixedly installed with a data rod 502. One end of the data rod 502 away from the relay 101 has a display 503, and the display 503 is slidably attached to the surface of the meter box 1. A sliding groove 504 is opened on the side end of the meter box 1 close to the data rod 502 (for details, please refer to Figure 1 ). Specifically, when it is necessary to disassemble the meter to avoid the alarm on the meter from sounding, push the display 503, so that the data rod 502 drives the relay 101 to start moving, the control rod 501 pushes the control block 411 to move, and the control block 411 pushes the disconnecting piece 408 to contact the brush block 306, so that the alarm will not be triggered when the circuit is disassembled.

[0043] Please refer to Figures 1 to 8, a false lock hole 505 is fixedly installed on the side end of the meter box 1 close to the control block 411. A pry bar 506 is rotatably arranged in the false lock hole 505. One end of the pry bar 506 away from the false lock hole 505 is slidably installed with a linkage rod 507. One end of the linkage rod 507 away from the pry bar 506 is rotatably installed with a power-on rod 508. The sliding expansion of the linkage rod 507 enables the power-on rod 508 to move vertically up and down, avoiding damage caused by the shaking of the power-on rod 508. The power-on rod 508 is slidably arranged at the upper end of the inner wall of the meter box 1, and the power-on rod 508 is arranged directly above the power-on block 305 and the brush block 306. A elastic rope 509 is fixedly installed between the power-on rod 508 and the meter box 1. The elastic rope 509 causes the pry bar 506 to tilt upward under normal circumstances, and the power-on rod 508 does not contact the brush block 306. Specifically, when a thief places a key or other item in the false lock hole 505, the pry bar 506 is pushed open, causing the pry bar 506 to start rotating. The linkage rod 507 drives the power-on rod 508 to slide, and the power-on rod 508 connects the power-on block 305 and the brush block 306, enabling the alarm 308 to be powered on. Thus, an obvious trap is used to lure the thief into triggering the alarm, preventing the meter from being violently removed.

[0044] The working principle of the present invention is as follows: When installing the meter, pull the incoming power connector 102, the control rope 410 pulls the disconnecting piece 408 to move, compressing the push spring 409, straightening the wire. The wire is cut to an appropriate length and connected to the incoming power connector 102, and the wire is fixed. Fasten the rotating buckle 203 and turn the rotating buckle 203, so that the rotating buckle 203 drives the drying bag 204 to start rotating. The bag-breaking piece 205 cuts the drying bag 204, and the calcium chloride dust particles stored in the drying bag 204 wrap the connector, thereby protecting the connector from getting damp and rusty. At the same time, after the calcium chloride dust particles absorb water vapor, they are converted into a gel to wrap the connector, isolating the connector from the air, and can achieve a better moisture-proof effect.

[0045] When the wire is cut, the threaded coil 402 does not generate an electromagnetic field, and the electromagnetic rod 404 moves downward under the action of gravity, pushing the push spring 409 to push the disconnecting piece 408 to move, connecting the power-on block 305 and the brush block 306, and enabling the alarm 308 to sound an alarm, thereby preventing the meter from being stolen;

[0046] At the same time, when a power outage occurs, the electromagnetic rod 404 drives the power-on piece 406 to move downward, and the power-on piece 406 contacts the power-on block 305, but the disconnecting piece 408 still separates the power-on block 305 and the brush block 306, preventing the alarm from being triggered in the event of a power outage or the circuit breaker being turned off;

[0047] Moreover, a trap is provided in the control mechanism 5. When a thief places a key or other item in the false keyhole 505, the pry bar 506 is pushed open, causing the pry bar 506 to start rotating. The linkage rod 507 drives the energizing rod 508 to rotate. The energizing rod 508 connects the energizing block 305 to the brush block 306, energizing the alarm 308, thereby using an obvious trap to lure the thief into triggering the alarm and preventing the electricity meter from being violently removed.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
