Description

Technical Field

[0001] The present invention relates to the technical field of electricity meters, and specifically to a remote monitoring and control intelligent electricity meter based on the Internet of Things. Background Art

[0002] Electricity meters are widely used in households, commercial buildings, industrial facilities, etc. With the development of smart grid technology, the application of smart electricity meters is becoming more and more extensive. They not only improve the efficiency of power management, but also contribute to energy conservation and emission reduction and the optimal allocation of power resources. The wiring terminals of electricity meters are the key parts for connecting the electricity meters to external circuits. They are responsible for correctly connecting the electricity meters to the circuits to ensure that the electricity meters can accurately measure electric energy.

[0003] Chinese Patent with application number 2021207148683 discloses a fast-wiring type intelligent electricity meter, which relates to the technical field of intelligent electricity meters and includes a meter body. A groove is opened at the bottom end of the meter body. A wiring head for connecting the live wire and the neutral wire is arranged in the groove. The wiring head adopts a concave structure. A copper sheet is attached to the inner bottom end of the wiring head. A pressing terminal that slides in it is arranged on the wiring head. An adjusting mechanism for adjusting the pressing terminal is arranged in the groove. The inner wall of the wiring head is provided with an inclined surface, and the height of the inclined surface increases from inside to outside. The pressing terminal is composed of a connecting block, a terminal frame and a terminal. The terminal is horizontally arranged in the wiring head. However, after long-term use, a large amount of impurities and dust will adhere to the wiring part of the electricity meter, which will accelerate the corrosion and damage of the wiring terminals of the electricity meter. Moreover, the conductors at the wiring part are directly exposed to the outside, which is likely to cause open circuits and electric shock accidents. In addition, when connecting the external power supply cable to the electricity meter, it is easy to deviate, and the end of the cable cannot be in good contact with the input end of the electricity meter.

[0004] In addition, in actual use, due to the complexity of the meter installation environment, such as factors like vibration, wind blowing, and human pulling, the cable is prone to looseness or even detachment, resulting in poor contact and power-off of the circuit. Summary of the Invention

[0021] 3. When the loose power supply cable loosens further in the present invention, first fix the loose power supply cable by the above method, then close the second control valve to maintain the fixation.

Specific embodiments

[0028] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-5 , the present invention provides a remote monitoring and control intelligent electric meter based on the Internet of Things, including a meter body 1. One side of the bottom of the meter body 1 is provided with a wiring base 101. The bottom of the wiring base 101 is provided with an input port 102 for connecting to an external power supply cable. The side of the wiring base 101 is provided with an output port 103 for the power output cable. Fixed studs are threadedly connected to both the input port 102 and the output port 103. The fixed studs are used to fix the ends of the cables connected to and led out of the meter body 1. As Figure 2 shown, the fixed studs corresponding to the input port 102 and the output port 103 are both located on the side of the wiring base 101, that is, the conductors between the power supply cable and the meter body 1 and between the power output cable and the meter body 1 are both located on the side of the wiring base 101.

[0030] A battery pack, a controller, and a wireless communication module are provided inside the meter body 1. The battery pack is used to supply power to each load on the meter body 1. The controller controls the actions of each driving component by receiving signal instructions. The wireless communication module is preferably an NB-loT module and is used for wireless connection with an external control terminal to achieve remote wireless control and monitoring.

[0031] At the position corresponding to the wiring base 101 at the bottom of the meter body 1, a sealing unit 2 is provided. The sealing unit 2 is used for sealing the input port 102 and the output port 103. The sealing unit 2 includes a sealing cover 201. The sealing cover 201 is of a cuboid structure. Both adjacent sides of the sealing cover 201 are transparent. The two transparent sides of the sealing cover 201 correspond to the bottom surface of the meter body 1 and the side surface of the wiring base 101 respectively. On the side of the sealing cover 201 opposite to the wiring base 101, a pressing plate 202 is provided. Between the pressing plate 202 and the sealing cover 201, there is a corrugated expansion bag 203. The corrugated expansion bag 203 is made of an elastic material. Both the pressing plate 202 and the corrugated expansion bag 203 are of a U-shaped structure. The inside of the pressing plate 202 is hollow and is communicated with the corrugated expansion bag 203. A pressing groove 205 is formed on the inner side of the pressing plate 202. The pressing groove 205 corresponds to the position of the output port 103. The pressing groove 205 is used for positioning the electric energy output cable led out of the meter body 1, and there is a gap between the pressing groove 205 and the electric energy output cable. Magnetic sheets are correspondingly embedded on the inner side surface of the pressing plate 202 and the side surface of the wiring base 101. The magnetic poles of the opposite side surfaces of the two magnetic sheets are opposite, so that the pressing plate 202 is actively attracted to the wiring base 101. An electric telescopic mechanism 204 is provided on the side surface of the meter body 1. The telescopic end of the electric telescopic mechanism 204 is fixedly connected to the side surface of the sealing cover 201. The electric telescopic mechanism 204 is preferably an electromagnetic telescopic device. By driving the sealing cover 201 to extend and contract, the sealing cover 201 is correspondingly separated from and close to the wiring base 101. In the process of the electric telescopic mechanism 204 extending to separate the sealing cover 201 from the wiring base 101, the electric telescopic mechanism 204 first drives the sealing cover 201 to move, so that the sealing cover 201 gradually moves away from the wiring base 101. Under the action of the attraction of the magnetic sheets on both sides, the corrugated expansion bag 203 is gradually stretched, while the pressing plate 202 remains stationary. When the pulling force of the corrugated expansion bag 203 on the pressing plate 202 overcomes the attraction of the magnetic sheets on both sides, the corrugated expansion bag 203 can drive the pressing plate 202 to move, so that the pressing plate 202 is separated from the wiring base 101.

[0032] Guide grooves 208 are formed on both sides of the wiring base 101. A guide seat 209 is slidably fitted in the guide grooves 208. The guide seat 209 is fixedly connected to the inner side of the sealing cover 201. The cooperation between the guide grooves 208 and the guide seat 209 provides guidance for the movement of the sealing cover 201 towards the wiring base 101 to prevent deviation.

[0033] At the position corresponding to the input port 102 at the bottom of the meter body 1, a guiding unit 3 is provided. The guiding unit 3 is used to introduce the external power supply cable into the input port 102. The guiding unit 3 includes a pipe seat 301, a hollow seat 306 and a guide wheel 311. The pipe seat 301 is arranged on the bottom surface of the wiring seat 101 through a support 302. The top surface of the pipe seat 301 is provided with support rods at equal intervals. The hollow seat 306 is arranged on the top of the support rods. A limiting groove 307 is opened in the middle of the side surface of the hollow seat 306. The limiting groove 307 is used for limiting the power supply cable. Guide columns 308 are arranged at both ends of the side surface of the hollow seat 306. The guide wheel 311 is rotatably connected between the ends of the guide columns 308 on both sides. A groove is opened on the circumferential surface of the guide wheel 311. In the initial state, the maximum gap between the groove and the limiting groove 307 is the same as the diameter of the power supply cable. A displacement sensor is arranged on the end surface of the guide wheel 311. The guide wheel 311 corresponds to the limiting groove 307 and the input port 102 in position. When the meter body 1 accesses the external power supply cable, the stripped end of the power supply cable is inserted through the gap between the groove and the limiting groove 307, and then it can directly enter the input port 102 along the guidance of the guide wheel 311, so that the stripped end of the power supply cable just corresponds to the end of the fixing stud.

[0034] During use, after the meter body 1 is fixed, the electric telescopic mechanism 204 is used to drive the sealing cover 201 to move by elongation. The sealing cover 201 moves to the side away from the wiring seat 101, so that the side surface of the wiring seat 101 is exposed. The power supply cable and the power output cable are respectively connected to the wiring terminals of the meter body 1. When connecting the power supply cable to the meter body 1, the end of the power supply cable is stripped to expose the internal conductor. The end of the power supply cable is inserted through the gap between the groove in the middle of the guide wheel 311 and the limiting groove 307. The guide wheel 311 rotates accordingly until the stripped position of the end of the power supply cable corresponds to the end of the fixing stud. At this time, tightening the fixing stud can fix the power supply cable. When connecting the power output cable to the meter body 1, the insulating layer at the end of the power output cable is stripped to expose the internal conductor, and the end of the power output cable is inserted into the output port 103, and the power output cable corresponds to the pressure groove 205. Tighten the fixing stud to fix the end of the power output cable.

[0035] After the meter body 1 is connected to the circuit, start the electric telescopic mechanism 204 to drive the sealing cover 201 to contract. When the pressing plate 202 approaches the wiring seat 101, the magnetic sheets on both sides are attracted to each other, so that the pressing plate 202 is tightly adsorbed on the side surface of the wiring seat 101. The pressure groove 205 corresponds and cooperates with the power output cable, as Figure 1 shown, to realize the sealing of the wiring part of the meter body 1 and prevent short circuits and electric shock accidents caused by the attachment of external impurities and floating objects.

[0036] However, during use, a relatively large amount of heat is generated at the side wiring of the terminal block 101. The sealing cover 201 cannot quickly dissipate the heat, resulting in too high a temperature inside the sealing cover 201, causing the conductor resistance to increase, generating a relatively large amount of power loss, and affecting the power supply effect. Therefore, the following improvements are made:

[0037] An exhaust valve 206 and an intake valve 207 are respectively provided on the outer and inner sides of the corrugated expansion bladder 203. A temperature sensor 210 is provided inside the sealing cover 201. The exhaust valve 206 is used to achieve one-way exhaust of the corrugated expansion bladder 203 to the outside, and the intake valve 207 is used to achieve one-way absorption of external air by the corrugated expansion bladder 203.

[0038] During use, when the temperature sensor 210 detects that the temperature inside the sealing cover 201 is greater than the set temperature threshold, it actively determines that the inside of the sealing cover 201 is in a high-temperature state. At this time, the electric telescopic mechanism 204 is activated to drive the sealing cover 201 to expand and contract. The expansion and contraction of the corrugated expansion bladder 203 is realized in the state where the magnetic sheets on both sides are attracted. When the corrugated expansion bladder 203 is stretched, the internal volume of the corrugated expansion bladder 203 increases, and at the same time, the intake valve 207 is in an open state to achieve air extraction. The high-temperature air inside the sealing cover 201 is pumped into the corrugated expansion bladder 203 through the intake valve 207. At the same time, the air outside the sealing cover 201 is supplemented into the sealing cover 201 through the gap at the pressure groove 205. When the corrugated expansion bladder 203 is compressed, the exhaust valve 206 is in an open state, and the high-temperature air inhaled into the corrugated expansion bladder 203 is squeezed out through the exhaust valve 206. Thus, through this cycle, by the reciprocating expansion and contraction of the electric telescopic mechanism 204, the high-temperature air inside the sealing cover 201 can be discharged when the inside of the sealing cover 201 is in a high-temperature state, realizing heat dissipation inside the sealing cover 201 and ensuring that the terminal block 101 is in a good conductive state.

[0039] In addition, in actual use, due to the complexity of the electricity meter installation environment, such as factors like vibration, wind blowing, and human pulling, the cable is prone to looseness or even detachment, resulting in poor contact or power outage. Therefore, the following improvements are made:

[0040] As Figure 5 shown, the end of the guide post 308 slidably penetrates through the side of the hollow seat 306 and extends into the hollow seat 306. A limiting spring 310 is sleeved on the guide post 308. The two ends of the limiting spring 310 are respectively fixedly connected to the guide post 308 and the hollow seat 306. After high-pressure gas enters the hollow seat 306, the air pressure inside the hollow seat 306 increases, which can cause the guide post 308 to extend outward, and successively adjust the distance between the groove and the limiting groove 307.

[0041] A control hose 312 is fixedly connected to the top of the socket 301. The end of the control hose 312 is fixedly connected to the hollow seat 306. A second control valve 313 is provided on the control hose 312. An air intake pipe 314 is fixedly connected to the end of the socket 301. The end of the air intake pipe 314 is fixedly connected to the pressing plate 202. The high-pressure gas in the corrugated expansion bladder 203 enters the socket 301 through the air intake pipe 314. When the second control valve 313 is in the open state, the high-pressure gas in the socket 301 enters the hollow seat 306 through the control hose 312.

[0042] During use, due to the fitting of the power supply cable with the guide wheel 311, when the power supply cable becomes loose, the guide wheel 311 will rotate slightly. At the same time, the displacement sensor detects the slight rotation of the guide wheel 311. At this time, the second control valve 313 corresponding to the loose power supply cable is opened, so that the electric telescopic mechanism 204 extends rapidly, causing the sealing cover 201 to drive the corrugated expansion bladder 203 to be stretched rapidly. At this time, both the exhaust valve 206 and the intake valve 207 are in the closed state. The air extraction effect generated by the stretching of the corrugated expansion bladder 203 makes the inside of the hollow seat 306 corresponding to the loose power supply cable in a negative pressure state through the air intake pipe 314, the socket 301 and the control hose 312, and generates a suction force on the inner end of the guide post 308, causing the inner end of the guide post 308 to slide into the hollow seat 306, and the limiting spring 310 is compressed, reducing the space between the groove and the limiting groove 307. At this time, the maximum circumferential side of the guide wheel 311 is in contact with the side of the hollow seat 306, so that the guide wheel 311 can tightly press the loose power supply cable to position the loose power supply cable and prevent the power supply cable from becoming loose again. Then, the second control valve 313 is closed to maintain the positioning state of the loose power supply cable.

[0043] Further, the support rod is a telescopic rod. The support rod includes a support cylinder 303 and a sliding cylinder 304. The bottom of the support cylinder 303 is fixedly connected to the socket 301. The sliding cylinder 304 is slidably fitted in the support cylinder 303. A first control valve 305 is provided on the support cylinder 303. Initially, the first control valve 305 is in the closed state, and the support cylinder 303 and the sliding cylinder 304 will not slide relative to each other. The top of the sliding cylinder 304 is fixedly connected to the bottom of the hollow seat 306. When the first control valve 305 is in the open state, the gas entering the socket 301 enters the sliding cylinder 304 through the support cylinder 303, causing the sliding cylinder 304 to extend out of the support cylinder 303, realizing the upward movement of the hollow seat 306.

[0044] However, when the displacement sensor detects that the guide wheel 311 makes a large rotational movement and the circuit is in a power-off state, it is actively determined that the connection between the end of the power supply cable and the terminal block 101 has become detached. That is, when a slight rotation of the loose power supply cable is detected and it continues to rotate, at this time, when the guide wheel 311 makes a slight rotational movement in the initial stage, the above method is first used to fix the loose power supply cable. Then, with the power supply cable positioned, the second control valve 313 is closed to maintain the fixed state of the loose power supply cable. When the guide wheel 311 continues to rotate, the first control valve 305 is opened, and the electric telescopic mechanism 204 is activated to drive the sealing cover 201 to contract, causing the corrugated telescopic bladder 203 to be compressed. At this time, the exhaust valve 206 and the intake valve 207 are still in the closed state. The high-pressure gas generated by the compression of the corrugated telescopic bladder 203 sequentially passes through the air guide pipe 314 and the pipe seat 301 and enters the support cylinder 303, causing the sliding cylinder 304 to extend and drive the hollow seat 306 to move upward. By using the positioning of the power supply cable by the guide wheel 311, the guide wheel 311 and the hollow seat 306 jointly drive the loose power supply cable to move upward, so that the end of the loose power supply cable remains in contact with the conductor in the input port 102. Then, the first control valve 305 is closed to maintain the extended state of the sliding cylinder 304 and continuously provide support for the loose power supply cable, thereby ensuring the normal supply of electric energy. At the same time, a signal is sent to the external control terminal through the wireless communication module to remind the user to perform maintenance and repair on the wiring of the meter body 1. After the maintenance and repair are completed, the corrugated telescopic bladder 203 returns to its initial state, and the limit spring 310 resets, releasing the fixing and supporting state of the guide wheel 311 on the power supply cable.

[0045] It should be noted that the loosening and detachment of the power supply cable is a slow process. The generation time of the negative pressure and high pressure in the hollow seat 306 is sufficient to drive the guide wheel 311 to act quickly and intervene in time in the loosening or detachment of the power supply cable. In addition, when the corrugated telescopic bladder 203 is stretched, since the magnetic sheets between the pressing plate 202 and the terminal block 101 are attracted to each other, the pressing plate 202 will not move together with the corrugated telescopic bladder 203.

[0046] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
