Description

Technical Field

[0001] The invention relates to the field of electric energy meters, and in particular to an intelligent anti-electricity theft electric energy meter. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities.

[0003] When using an energy meter, please note that in the case of low voltage (no more than 500 volts) and small current (tens of amperes), the energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the energy meter cannot be directly connected to the circuit and must be used in conjunction with a voltage transformer or current transformer.

[0004] With the development of science and technology, anti-electricity theft energy meters have also been designed. They are equipped with carrier communication modules and periodically send information such as electricity consumption to the background. The background determines whether the electricity consumption of the relevant users is normal based on the data and a reasonable circuit loss value. With the carrier communication module opened on such anti-electricity theft energy meters being installed in the corresponding installation slot, and when the box cover is opened, the carrier communication module can also send relevant data such as the time and place of opening to the background. However, such a design still makes it easier for the carrier communication module to be removed, which makes it easy for electricity thieves to interfere with the carrier communication module, thereby affecting its normal and accurate monitoring of the data. At the same time, the existing anti-electricity theft energy meters still use traditional bolt installation for the connection of wires, which makes the installation more inconvenient and not fast enough. For example, the Chinese patent with application number CN202310368402.6 discloses "an anti-theft electric energy meter, including an electric meter housing, the electric meter housing having an electric meter connection for wiring and connecting a circuit, and the electric meter housing having an instrument for displaying counting data, an external fixing frame fixedly connected to the wiring position at the lower end of the electric meter housing, two limiting clamps are arranged in the external fixing frame, and the electric meter connection is located between the two limiting clamps; if the wiring mode needs to be changed, the first anti-theft plate and the second anti-theft plate need to be removed, the mutual lead plate contacts the power connection connector in a certain regularity, and the occurrence of electric theft is detected by the constant change of the current, and the toggle rod can squeeze the elastic cutter and cut off the passage of the electric meter connection and the second lead, disconnect the operation of the instrument, so that the overall electric energy meter can timely detect the fluctuation of abnormal electric quantity and the increase in the difficulty of wiring when preventing theft, and reduce the phenomenon of electric quantity loss caused by the change of wiring mode". However, the above technical scheme can achieve effective prevention and control of electric theft, but cannot achieve good stabilization of the carrier communication module installed in the existing electric energy meter.

[0016] Compared with the related art, the intelligent anti-electricity theft electric energy meter provided by the present invention has the following beneficial effects: 1. The present invention provides an intelligent anti-electricity theft energy meter. When installing the energy meter, the energy meter can be installed at the required wall position first. Then, when wiring, the communication slot cover and the power connection slot cover can be opened first, and then the carrier communication module can be card-mounted in the communication module slot, and the power connection slot cover can be opened. Then, the wires to be connected can be stripped of wire sheaths using a wire stripper, and then the wire cores can be wound into a circle and inserted into the power connection terminals. Then, the screws on both sides can be driven to rotate synchronously, and then the pressing plate and the wire pressing terminal can be driven to move backward respectively, until the wire pressing terminal moves into the power connection slot to squeeze the wire core wound in the power connection terminal, so that one operation can be achieved to squeeze the wire cores on multiple power connection terminals synchronously, and a stable connection can be achieved.

[0017] 2. The present invention provides an intelligent anti-electricity theft energy meter. When the pressing plate moves backward, the supporting plate can be synchronously driven to move backward through the contact plate fixedly connected to the pressing plate, thereby driving the rotating rod to rotate, so as to push the push rod to drive the mounting plate to move into the slot, so that the sliding column at the end of the rotating plate A rotatably connected to each mounting plate can contact the inner wall of the slot, and then the two rotating plates A gradually rotate, driving the sliding columns on both sides to move away from each other and respectively contact and fit with the inner walls of the two sides of the slot. At this time, the sliding column will also move to the front side of the L-shaped limiting slide plate, so that the sliding column can be The column limits the L-shaped limit slide plate, thereby realizing the stable installation of the carrier communication module. At the same time, the backward movement of the pressure plate can also drive the front clamping block to move backward. At this time, it is only necessary to lift the cover plate to contact with the bottom of the electric energy meter, and the front clamping block can be moved backward to make it gradually cooperate with the rear clamping block on the cover plate. At this time, the cover plate can be firmly installed at the bottom of the power connection slot, and when the pressure plate drives the front clamping block to move forward, the elastic force of the spring C can be used to drive the cover plate to move backward, thereby leaving more space for facilitating the installation of the cable on the power connection terminal.

[0018] 3. The present invention provides an intelligent anti-electricity theft energy meter. By rotating the circular ring on the outer side of the rotating ring, the support plate can be rotated away from the bottom of the contact plate. Then, when the pressure plate is in the installation state on the rear side, the contact between the support plate and the contact plate can be eliminated by simply rotating the circular ring. Then, under the elastic force of the spring, the rotating ring is driven to move forward, and then the sliding column is pulled back into the opening, and the limitation on the carrier communication module is eliminated, so that the carrier communication module can be directly taken out from the communication module slot, and the carrier communication module can be replaced or repaired. After reinstallation, the carrier communication module can be first installed in the communication module slot, and then the rotating ring is pressed by the elastic force of the customer spring B to move it to the rear side of the contact plate, and then the rotating ring is rotated again so that the support plate can be installed here on the rear side of the contact plate.

[0019] 4. The present invention provides an intelligent anti-electricity theft energy meter, which is equipped with a push block in the carrier communication module, and can be pressed to drive the rotating plates B on both sides to rotate, and drive the L-shaped limit slides on both sides to move away from each other, so that the limit of the L-shaped limit slide and the slide column is cancelled. At this time, the carrier communication module can be taken out from the communication module slot, but it is only used in emergency situations, because when the carrier communication module is taken out, the detachment alarm installed between it and the communication module slot will alarm with a timing alarm. At this time, due to the removal of the carrier communication module, the slide column will be driven by the rotating plate B to reset to the position limited by the limit bevel block. At this time, if it is reinstalled again, the power connection slot cover can only be opened first. The power connection slot cover is locked with the energy meter through an electronic lock, and can only be opened by background remote control. In this way, it can also be prevented that irrelevant personnel will open the communication slot cover at will and take out the carrier communication module, thereby increasing the safety of use.

[0020] This allows the device to connect electric wires conveniently, efficiently and quickly, and can also install the carrier communication module stably and safely. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1: See also Figure 1-4 , 8-9, the present invention provides a technical solution: an intelligent anti-electricity theft electric energy meter, comprising an electric energy meter 1, a communication module slot 2, a power connection slot 3, a communication slot cover 4, a power connection slot cover 5, a bottom cover 6, a threading hole 7, a carrier communication module 8, and a power connection board 9.

[0033] Among them, the electronic lock is remotely controlled to realize the opening and closing of the power connection slot cover 5 and the power connection slot 3, and the bottom of the carrier communication module 8 and the rear inner wall of the communication module slot 2 are respectively provided with conductive terminals. There will be no alarm when the two are in contact, but an alarm will be issued when the two are out of the set time. The specific time can be set according to the usage scenario.

[0034] A communication slot cover 4 is installed on the outer side of the communication module slot 2 through a hinge, and a power connection slot cover 5 is installed on the outer side of the power connection slot 3 through a hinge.

[0035] A power board 9 is fixedly installed on the inner wall of the rear side of the power connection slot 3, and a power connection slot 10 is arranged in an array on the front surface of the power connection plate 9, and a power connection terminal 11 is fixedly sleeved on the inner wall array of the power connection slot 10. Two openings 12 are symmetrically arranged between the communication module slot 2 and the power connection slot 3. Slide bars A13 are arranged on the upper and lower sides of the left and right ends of the power connection plate 9, and the rear end of each slide bar A13 is fixedly connected to the inner wall of the rear side of the power connection slot 3. A pressing plate 14 is slidably sleeved between each slide bar A13, and the lower end surface array of the pressing plate 14 is arranged on the lower end surface of the pressing plate 14. A plurality of crimping terminals 1401 are fixedly connected, and the outer side surface of each slide rod A13 is sleeved with a spring A15, the upper side of the pressing plate 14 is fixedly connected with a contact plate 16, and the left and right ends of the contact plate 16 are also fixedly connected with extension plates 17, the left and right sides of the lower end of the pressing plate 14 are fixedly connected with front clamping blocks 18, the left and right sides of the rear inner wall of the power connection slot 3 are fixedly connected with screws 19, each extension plate 17 is threadedly sleeved on the outer side of the screw 19 on one side, and the left and right sides of the bottom cover 6 are provided with a closing mechanism; The screw rod 19 can be rotated to drive the extension plate 17 threadedly sleeved therewith to move backward, thereby driving the pressing plate 14 and the abutting plate 16 to move backward synchronously, and also driving the front clamping block 18 to move backward synchronously.

[0036] The left and right sides of the inner wall of the rear side of the power connection slot 3 are also fixedly connected with a guide slide bar 20, and the outer rotating sleeve of the guide slide bar 20 is provided with a swivel ring 21, and the front end of the swivel ring 21 is fixedly connected with a support plate 2102, and the outer rotating sleeve of the lower end of the swivel ring 21 is provided with a circular ring 2101, and the rear end of the circular ring 2101 and the other side relative to the support plate 2102 are rotatably connected with a rotating rod 2103, and the other end of the rotating rod 2103 is rotatably connected with a push rod 2104, and the upper end of the push rod 2104 is fixedly connected with a mounting plate 2105, and each mounting plate 2105 is slidably connected in the opening 12 on its own side, and the carrier communication The left and right sides of the lower end of the module 8 are respectively provided with card slots 22 corresponding to the openings 12 on both sides, and a locking mechanism is arranged between the mounting plate 2105 and the card slot 22. A disassembly mechanism is also arranged in the carrier communication module 8, and the front side surface of the support plate 2102 is fitted and connected with the rear end surface of the contact plate 16, so that when the pressure plate 14 is driven to move backward, the support plate 2102 and the contact plate 16 are fitted and contacted, and the rotating ring 21 can be synchronously driven to move backward, and the push rod 2104 can be pushed upward through the rotating rod 2103, thereby driving the mounting plate 2105 to slide upward in their respective openings 12.

[0037] In this way, when installing, the energy meter 1 is installed on the wall at the required position, and then when wiring, the communication slot cover 4 and the power connection slot cover 5 can be opened first, and then the carrier communication module 8 can be clamped in the communication module slot 2, and then the wires to be connected can be stripped of the wire sheath with a wire stripper, and then the wire core can be wound into a circle and inserted into the power connection terminal 11, and then the screws 19 on both sides can be driven to rotate synchronously, and the pressure plate 14 can drive the wire pressing terminal 1401 to move backward, and the wire core on the power connection terminal 11 in the docking slot 10 can be pressed and stabilized.

[0038] Furthermore, since the swivel ring 21 is rotatable, it can drive the support plate 2102 to rotate through its own rotation, so that the support plate 2102 can rotate to the rear side of the contact plate 16 to contact it, or it can rotate away, thereby achieving the effect of moving down synchronously or asynchronously with the pressure plate 14.

[0039] Embodiment 2: See also Figure 1-9The present invention provides a technical solution: the locking mechanism includes a limiting inclined block 2106, a rotating plate A2107, and a sliding column 2108. One end of each mounting plate 2105 away from the push rod 2104 is fixedly connected to the limiting inclined block 2106. Both sides of each limiting inclined block 2106 are symmetrically rotatably provided with a rotating plate A2107. One end of the rotating plate A2107 is rotatably connected to the mounting seat 2105 through a spring hinge, and the other end is fixedly connected to a sliding column 2108. The sliding columns 2108 on both sides of each mounting seat 2105 slide on the left and right sides of the corresponding locking groove 22 respectively. A spring B2109 is also sleeved on the outer side of the guide slide bar 20. The front and rear ends of the spring B2109 are respectively fixedly connected to the rear end of the rotating ring 21 and the inner wall of the power connection groove 3.

[0040] The rotating plates A2107 on both sides of the limiting inclined block 2106 rotate toward the middle limiting inclined block 2106 under the action of the spring hinge, and are limited by the left and right sides of the limiting inclined block 2106. Each mounting plate 2105, rotating plate A2107, and sliding column 2108 slides in the opening 12 on one side thereof, and passes through the opening 12 to slide in the slot 22, and the sliding column 2108 slides in contact with the inner wall of the slot 22 on one side thereof.

[0041] In this way, in the process of driving the pressure plate 14 and the wire pressing terminal 1401 to move backward, the installation plate 2105 will also be driven to move upward in the opening 12 synchronously, and the rotating plate A2107 and the sliding column 2108 on both sides of the installation plate 2105 that are rotatably connected by spring hinges will gradually move into the slot 22 opened on the carrier communication module 8, so that the sliding column 2108 will contact the inner wall of the slot 22, and gradually rotate away from each other until they contact the inner walls of the two sides of the respective slots 22. At this time, since the L-shaped limiting slide plate 2302 is on the rear side of the sliding column 2108, the sliding column 2108 can limit it to achieve limited installation of the carrier communication module 8, so that even if the communication slot cover 4 can be opened, it is not easy to remove the carrier communication module 8.

[0042] The disassembly mechanism includes a concave groove 23, a slideway opening A2301, an L-shaped limiting slide plate 2302, a push block 2303, and a rotating plate B2304. The lower side of the carrier communication module 8 is symmetrically provided with two left and right concave grooves 23. Each concave groove 23 is provided with a slideway opening A2301 penetrating between the left and right inner walls of the card slot 22 on each side. The left and right sides of the concave groove 23 are symmetrically provided with L-shaped limiting slide plates 2302, and the lower ends of the L-shaped limiting slide plates 2302 on both sides are close to each other. The near side passes through the slide opening A2301 on each side and extends into the concave groove 23, and the extended end is on the rear side of the slide column 2108. The front end of the concave groove 23 passes through the front side of the carrier communication module 8 and is provided with a slide opening B2306, and a push block 2303 is slidably connected in the slide opening B2306. The left and right sides of the rear end of the push block 2303 are rotatably connected with a rotating plate B2304, and the other ends of the two rotating plates B2304 are respectively rotatably connected to the front ends of the L-shaped limiting slide plates 2302 on both sides.

[0043] In this way, by simply opening the communication slot cover 4, the L-shaped limiting slides on both sides can be driven away from each other by pressing the push block 2303, so as to cancel the limit between them and the slide post 2108, so that the carrier communication module 8 can be taken out directly. However, this method is only limited to emergency situations. Therefore, after taking out the carrier communication module 8 in this way, under the action of the spring hinge, the turn plate A2107 will rotate and reset. At this time, the slide post 2108 will also rotate to the front side of the mounting seat 2105. At this time, it will limit the carrier communication module 8 reinstalled in the communication module slot 2, making it impossible to install it. After a certain period of time, the detachment alarm will alarm the background.

[0044] If it needs to be reinstalled, it is necessary to contact the background control to open the electronic lock, so as to open the power supply slot cover 5, and then rotate the support plate 2102 to cancel the interference between it and the contact plate 16. Then, under the elastic force of the spring B2109, the swivel 21 moves forward and resets, and pulls the swivel plate A2107 and the slide column 2108 back into the opening 12. At this time, the carrier communication module 8 can be installed. After installation, press down the swivel 21 so that it drives the slide column 2108 to contact the slot 22 again, and limit it with the L-shaped limiting slide plate 2302. Then, when the swivel 21 moves to the rear side of the contact plate 16, rotate the swivel 21 again so that the support plate 2102 contacts the rear side of the contact plate 16 again to achieve installation.

[0045] This method effectively prevents unauthorized personnel from opening the communication slot cover 4, taking out the carrier communication module 8, and changing it, which affects the reliability of subsequent monitoring data. However, it can also take into account emergency opening. The electronic lock can only be opened after contacting the background, which also prevents the power-saving slot cover 5 from being opened at will and the cables from being privately connected to steal electricity.

[0046] Grooves 2305 are also provided on the left and right sides of the front side of the carrier communication module 8, and the grooves 2305 on both sides are respectively arranged above the slide openings B2306 on both sides. The design of the grooves 2305 is to facilitate pressing the push block 2303, and use two fingers to place in the grooves 2305 to lift out the carrier communication module 8.

[0047] Embodiment three: See also Figure 1-4 The present invention provides a technical solution: the cover closing mechanism includes a side frame 601, a connecting plate 602, a sliding rod B603, and a spring C604. The left and right sides of the bottom cover 6 are fixedly connected with the side frames 601, the left and right sides of the electric energy meter 1 are fixedly connected with the connecting plates 602, and the connecting plates 602 are fixedly connected with the sliding rod B603. Each side frame 601 is slidably sleeved on the outer side of the sliding rod B603 on its own side, and the outer side of the sliding rod B603 is also sleeved with a spring C604, and the upper and lower ends of the spring C604 are respectively fixedly connected to the side frame 601 and the connecting plate 602.

[0048] The bottom cover 6 is also fixedly connected to rear clamping blocks 605 on both sides of the upper end. Each rear clamping block 605 corresponds to the upper and lower positions of the front clamping block 18 on its side, and a corresponding inclined surface is provided on the side close to each other. The front clamping block 18 and the rear clamping block 605 on its side are locked in place through the inclined surfaces.

[0049] In this way, when the screw 19 is rotated to move the pressure plate 14 forward, after the front block 18 is disengaged from the rear block 605, the bottom cover 6 will be popped open under the action of the spring C604, leaving more space for connecting electricity in the power terminal 11. When the pressure plate 14 moves backward to press and fix the wire core in the power terminal 11, the bottom cover 6 can be simultaneously pushed upward to overcome the elastic force of the spring C604 and contact with the bottom of the electric energy meter 1. At this time, as the pressure plate 14 moves backward, the front block 18 will also be driven to gradually cooperate with the rear block 605 to achieve a stable and fitting installation of the bottom cover 6 at the bottom of the electric energy meter 1.
