Description

Technical Field

[0001] The present invention relates to the technical field of electric meter equipment, in particular to an electric meter that is easy to disassemble and maintain. Background Art

[0002] Electricity meters that are easy to disassemble and maintain are used to measure and record electricity consumption. They are installed in various links of the power system to monitor electricity usage and help users understand actual electricity consumption for energy management and cost accounting. At the same time, the design of electricity meters that are easy to disassemble and maintain makes installation, maintenance and replacement more convenient and quick, thereby improving the efficiency and reliability of the electricity meter.

[0003] Given that the operation of an electric meter involves the connection of numerous power cords, these power cords are complex and tangled together, making it quite challenging to quickly identify the corresponding connection port. In addition, when performing maintenance work on a large number of power cords, disassembling and reconnecting these wiring harnesses is also cumbersome. Each time maintenance is performed, the staff needs to spend a lot of time and energy to handle these wiring harnesses, which undoubtedly increases the difficulty of maintenance work.

[0016] The present invention provides an electric meter that is easy to disassemble and maintain, and has the following technical points and beneficial effects:

[0017] 1. The present invention uses devices such as a liquid storage tube, a clip, and a bellows. When the wiring in the wiring port is powered off by pulling down the safety switch, the magnetic particles of the magnetorheological fluid lose the guidance of the magnetic field and return to a free-flowing Newtonian fluid state. At this time, the clip moves backward under the pull of the springs on both sides of the movable box, thereby canceling the fastening of the clamping rod and releasing the clamping plate, allowing the wiring to be freely pulled out. At the same time, the pressure plate pops up, making it easier for maintenance personnel to find the wiring port corresponding to the wiring and quickly locate the maintenance process.

[0018] 2. The present invention uses devices such as a buckle, a sleeve rod and a pressure rod. When it is necessary to take out the wires in the wiring ports at the same time, the push blocks on both sides are pushed backward to slide in the opening, and the push blocks drive the pressure rod to slide inward of the movable groove. At this time, the pressure rod simultaneously pushes the buckle inward, so that the buckle cancels the fastening of the clamping rod, and the pressure plate is released. The movable pressure rod bounces upward under the action of the electromagnetic spring coil, and the splint is loosened, which makes it convenient for the wires to be drawn out from the wiring ports at the same time. At this time, the staff can conveniently replace or check the wires in all wiring ports.

[0019] 3. The present invention uses devices such as a buckle, a pressing rod and a sleeve rod. When it is necessary to take out the wiring in the wiring port separately, the buckle is moved synchronously to the inside of the movable groove by pressing the pressing rod, so that the buckle cancels the buckling of the clamping rod. When the wiring in the wiring port is maintained or replaced, the movable pressure rod is pressed down by pressing the pressure plate and the electromagnetic spring coil is pressed down at the same time, so that the electromagnetic spring coil presses the sleeve rod downward under the elastic potential energy, so that the clamping plate below the sleeve rod presses and clamps the wiring, and the buckle re-fastens the fixed clamping rod to install and use the wiring.

[0020] 4. The present invention uses devices such as sliding rods, pressure rods and push blocks. When the terminal block needs to be removed from the electric meter for maintenance, the power supply to the wiring port is first disconnected. The maintenance personnel press the sliding rods in the openings on both sides to squeeze the two sides of the pressure rod, and then the pressure rod running through the openings on both sides undergoes elastic deformation and retracts into the terminal block. At this time, the terminal block is pulled outward and removed from the installation slot.

[0021] 5. The present invention uses devices such as fixing plugs, sockets and fixing rods. Maintenance personnel can install the electric meter on a wall, meter box or other supporting structure by rotating the fixing plug. The meter cover is engaged with the socket inside the meter through the fixing rod below it, thereby achieving installation of the meter cover. When the meter cover needs to be removed from the meter, the maintenance personnel can buckle the meter cover from the meter through the slot, and the fixing plug passes through the inside of the fixing hole and engages with the socket. The maintenance personnel can then manually rotate the fixing plug to install and disassemble the circuit board, thereby facilitating the maintenance personnel to disassemble and maintain the electric meter and other devices.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 14 The present invention provides a technical solution for an electric meter that is easy to disassemble and maintain:

[0039] An electric meter that is easy to disassemble and maintain, comprising an electric meter 1 and a mounting slot 8 on one side of the electric meter 1. A wiring terminal 3 is embedded and installed inside the mounting slot 8. Openings are provided on both sides of one end of the electric meter 1, and a push block 2 is embedded and movably installed in the opening. A slide bar 201 is embedded and movably installed on one side of the push block 2. A return spring 202 is embedded and installed in the opening, and the two sides of the return spring 202 are respectively fixedly connected to the electric meter 1 and the push block 2. A plurality of wiring ports 301 are provided on one side of the wiring terminal 3, and a mounting block 303 is fixedly installed equidistantly above the wiring terminal 3.

[0040] The inner side of the mounting block 303 is fitted with a pressure plate 9, and the pressure plate 9 is arranged corresponding to the wiring port 301. A clamping rod 901 is fixedly installed on both sides of one end of the pressure plate 9. A movable pressure rod 902 is fitted and movably installed below the pressure plate 9. A sleeve rod 903 is nested and installed below the movable pressure rod 902. The sleeve rod 903 penetrates and is movably installed on the inner side of the wiring port 301. An electromagnetic spring coil 9031 is fitted on the inner side of the sleeve rod 903. A clamping plate 904 for clamping the wiring is fixedly installed below the sleeve rod 903. A movable groove is provided on the inner side of the wiring terminal 3. Buckles 11 are provided on both sides of the movable pressure rod 902, and the clamping rod 901 is fixed on both sides of the clamping rod 903. The buckle 11 is located in the movable groove and is movably mounted. A push rod 10 is provided on one side of the buckle 11, and the push rod 10 is movably mounted in the movable groove. A movable box 12 is fixedly installed at equal distances on the inner side of the movable groove. A mounting box 1202 is provided in the middle of the movable box 12, and the mounting box 1202 is fixedly mounted in the movable groove. A bellows 1201 is fixedly installed in the middle of the inner side of the movable box 12, and the inner side of the mounting box 1202 is fixedly connected to a liquid storage tube 1203 filled with magnetorheological fluid. A flow groove 304 is provided on the inner side of the terminal 3, and the bellows 1201 is connected to the liquid storage tube 1203 through the flow groove 304.

[0041] As an embodiment of the present invention, Figures 1 to 14 As shown, a pressure rod 13 is provided below the push rod 10, and the pressure rod 13 is movably mounted in the movable groove and passes through the openings on both sides of the terminal 3. The pressure rod 13 is connected to the slide rod 201 by passing through the openings on both sides of the terminal 3.

[0042] When working, the terminal block 3 is installed and used through the installation slot 8, and the pressure plate 9 is installed and used through the installation clamp block 303. When the terminal block 3 needs to be removed from the meter 1 for maintenance, the power connection connected to the wiring port 301 is first disconnected, and the maintenance personnel presses the sliding rods 201 in the openings on both sides to squeeze the two sides of the pressure rod 13, so that the pressure rod 13 passing through the openings on both sides undergoes elastic deformation and retracts into the terminal block 3, at this time, the terminal block 3 is pulled outward and then removed from the installation slot 8. When the maintenance is completed, the terminal block 3 is reinstalled in its original position. At this time, the elastic potential energy of the pressure rod 13 pushes the slide bar 201 out of the push block 2, and then the slide bar 201 is reset, and the pressure rod 13 is buckled by the push block 2 to be fixed, and then the terminal block 3 is installed in the installation slot 8 for use;

[0043] When the wiring in the wiring port 301 needs to be taken out at the same time, the push blocks 2 on both sides are pushed back to make them slide in the openings, and the push blocks 2 drive the pressure rods 13 to slide toward the inside of the movable groove. At this time, the pressure rods 13 push the buckles 11 inward synchronously, so that the buckles 11 cancel the buckling of the clamping rod 901, and the pressure plate 9 is released. The movable pressure rod 902 bounces upward under the action of the electromagnetic spring coil 9031, and the clamping plate 904 is loosened, making it easy to draw the wiring from the wiring port 301 at the same time. At this time, the staff can easily replace or check the wiring in all the wiring ports 301. Secondly, the reset spring 202 is used to reset the push block 2. When the wiring in the wiring port 301 is taken out separately, the push rod 10 is pressed to make The buckle 11 moves synchronously toward the inside of the movable groove, and similarly cancels the buckle 11 from buckling the clamping rod 901. Since the pressure rod 13 is staggered below the pressing rod 10, when the wiring in the wiring port 301 is taken out separately, it will not affect the buckling state of the pressure rod 13 and the other buckles 11, thereby ensuring the independence of operation. At this time, the staff can check the wiring in the wiring port 301 separately. When the wiring in the wiring port 301 is maintained or replaced, the movable pressure rod 902 is pressed down by pressing the pressure plate 9 and the electromagnetic spring coil 9031 is pressed down at the same time, so that the electromagnetic spring coil 9031 presses the sleeve rod 903 downward under the elastic potential energy, so that the clamping plate 904 below the sleeve rod 903 presses and clamps the wiring, and the buckle 11 re-fastens the fixed clamping rod 901 for wiring installation and use;

[0044] When the wiring is long and entangled with each other, it is inconvenient to inspect and maintain the safety switch corresponding to the wiring in the wiring port 301. Therefore, in the design of the wiring terminal 3, a movable box 12 and an installation box 1202 are added, and a liquid storage tube 1203 is provided in the installation box 1202, and a bellows 1201 is provided in the movable box 12. The spring and push plate in the installation box 1202 squeeze the magnetorheological fluid through the flow groove 304 and transport it into the bellows 1201. When the electromagnetic spring coil 9031 is connected to the conductive sheet 302, the current flowing through the electromagnetic spring coil 9031 will generate a magnetic field. At this time, the magnetic particles in the magnetorheological fluid will quickly arrange themselves in the direction of the magnetic field to form a chain or columnar structure, the viscosity of the fluid will increase sharply, and the fluidity will decrease, so that the magnetorheological fluid will be converted into a Bingham fluid (Bingham fluid is also called plastic fluid, which means that when the cutting When the stress reaches a certain yield stress, shear deformation begins to occur, and the deformation rate and shear stress are linearly related). At this time, the magnetorheological fluid in the form of a Bingham fluid in the bellows 1201 will support the buckle 11 to prevent the springs on both sides of the movable box 12 from pulling the buckle 11 inward under the elastic potential energy, so that it cancels the fastening to the clamping rod 901. When the wiring in the wiring port 301 is powered off by pulling down the safety switch, the magnetic particles of the magnetorheological fluid lose the magnetic field guidance and return to the free-flowing Newtonian fluid state. At this time, the buckle 11 moves backward under the pull of the springs on both sides of the movable box 12, thereby canceling the fastening to the clamping rod 901, and then releasing the splint 904, so that the wiring can be freely pulled out, and at the same time, the pressure plate 9 pops up, so that the maintenance personnel can find the wiring port 301 corresponding to the wiring for quick positioning maintenance.

[0045] As an embodiment of the present invention, Figures 1 to 7 As shown, a meter cover 4 is provided above the meter 1, and fixing rods 401 are fixedly installed at the four corners below the meter cover 4. Slots 101 are provided on both sides of the meter 1, and holes 104 are provided on the inner side of the meter 1. The meter cover 4 is mounted on the top of the meter 1 by means of the fixing rods 401 so as to be engaged with the holes 104. An observation window 5 is provided on one side of the meter cover 4, and a reporting template 102 is provided below the other side of the meter cover 4. A partition 106 is fitted on the inner side of the meter 1. Fixing blocks 6 are fixedly installed at the four corners of the meter 1, and fixing plugs 7 for mounting the meter 1 are fitted on the inner side of the fixing blocks 6.

[0046] During operation, the meter cover 4 is engaged with the socket 104 inside the meter 1 through the fixing rod 401 below it, thereby achieving the installation of the meter cover 4. When the meter cover 4 needs to be removed from the meter 1, the maintenance personnel can buckle the meter cover 4 from the meter 1 through the slot 101. An observation window 5 is provided on one side of the meter cover 4 to facilitate maintenance personnel to observe the data displayed on the display 107 inside the meter 1 on site, while the reporting template 102 below the other side is used for data exchange and communication to transmit the data detected by the meter 1 to an external monitoring device. The reporting template 102 is installed by the partition 106 installed by the inner side of the meter 1. At the same time, the circuit board 105 inside the meter 1 can be isolated from other components to reduce interference and improve the stability and safety of the meter 1. The maintenance personnel can install the meter 1 on a wall, meter box or other supporting structure by rotating the fixing plug 7 installed by the fixing block 6.

[0047] As an embodiment of the present invention, Figures 1 to 5 As shown, pressure blocks 103 are fixedly mounted on both sides of the partition 106, and the reporting template 102 is mounted on the top of the partition 106 through the pressure blocks 103. The inner sides of the pressure blocks 103 are provided with anti-slip sheets. A display 107 is fixedly mounted on one side of the circuit board 105, and the display 107 is connected to the reporting template 102 via the circuit board 105 and the reporting interface 108. A circuit board 105 is provided below the partition 106, and a socket 104 is provided below the circuit board 105. The socket 104 is fixedly connected to the electric meter 1. Fixing holes are penetrated on both sides of the circuit board 105, and the fixing plug 7 passes through the inner side of the fixing hole and is engaged with the socket 104.

[0048] During operation, the reporting template 102 is installed and used by inserting it between the pressure blocks 103. At the same time, the anti-slip sheet on the pressure block 103 can effectively prevent the reporting template 102 from sliding during use, so as to ensure that the reporting template 102 can be tightly installed on the partition 106. After receiving the signal transmitted by the circuit board 105, the reporting template 102 processes and analyzes the data through its internal processor, and displays the basic data of the electric meter 1 in real time through the display 107, so as to facilitate the maintenance personnel in monitoring the operating status of the equipment. Secondly, the fixing plug 7 passes through the inside of the fixing hole and is engaged with the socket 104, so that the maintenance personnel can install and remove the circuit board 105 by manually rotating the fixing plug 7.

[0049] As an embodiment of the present invention, Figures 2 to 8As shown, a reporting interface 108 is fixedly installed above the circuit board 105, and the reporting interface 108 is embedded with the reporting socket provided below the reporting template 102. A plurality of power connection plates 109 are provided on the inner side of the mounting groove 8, and the power connection plates 109 are electrically connected to the circuit board 105. A plurality of conductive plates 302 are provided on one side of the connection terminal 3, and the conductive plates 302 are installed through the inner side of the connection port 301. The circuit board 105 is electrically connected to the conductive plates 302 through the power connection plates 109.

[0050] During operation, the reporting template 102 (the reporting template 102 is a device for data exchange, which presents various faults and abnormal conditions detected by the electric meter 1 in a specific format and manner, and interacts with external devices or systems to transmit error information to the management platform for remote fault diagnosis and processing, so that maintenance personnel can intuitively understand the problem. This type of reporting template 102 device is common knowledge among those skilled in the art. In this technical solution, only this device is used and will not be described in detail here) is engaged with the reporting socket below the reporting template 102 and the reporting interface 108, and then the reporting template 102 is installed on the circuit board 105 for use. At the same time, the power connection plate 109 is fitted with the conductive plate 302. When the power connection is inserted into the connection port 301, power is transmitted to the power connection plate 109 through the conductive plate 302, so that the circuit board 105 and the reporting template 102 are powered and used.

[0051] Working principle: During installation, the maintenance personnel install the electric meter 1 on a wall, electric meter box or other supporting structure by rotating the fixing plug 7. The electric meter cover 4 is connected to the socket 104 inside the electric meter 1 through the fixing plug rod 401 below it, thereby realizing the installation of the electric meter cover 4. When the electric meter cover 4 needs to be removed from the electric meter 1, the maintenance personnel can buckle the electric meter cover 4 from the electric meter 1 through the slot 101. An observation window 5 is provided on one side of the electric meter cover 4 to facilitate the maintenance personnel to observe the data displayed on the display 107 inside the electric meter 1 on site, and the reporting template 102 below the other side is used for data exchange and communication to transmit the data detected by the electric meter 1 to the external monitoring equipment. The partition 106 installed by the inner side of the electric meter 1 is used to install the reporting template 102, and the circuit board 105 inside the electric meter 1 can be installed at the same time. The electric meter 1 is isolated from other components to reduce interference and improve the stability and safety of the electric meter 1. The reporting template 102 is installed and used by inserting it between the pressing blocks 103. At the same time, the anti-slip sheet on the pressing block 103 can effectively prevent the reporting template 102 from sliding during use, thereby ensuring that the reporting template 102 can be tightly installed on the partition 106. Secondly, the fixing plug 7 passes through the inner side of the fixing hole and is engaged with the socket 104, so that the maintenance personnel can install and remove the circuit board 105 by manually rotating the fixing plug 7. At the same time, the power connection sheet 109 is in contact with the conductive sheet 302. When the power connection is inserted into the connection port 301, the conductive sheet 302 transmits power to the power connection sheet 109, thereby enabling the circuit board 105 and the reporting template 102 to be powered and used;

[0052] When it is necessary to remove the terminal block 3 from the electric meter 1 for maintenance, the power supply connected to the wiring port 301 is first disconnected. The maintenance personnel press the slide bars 201 in the openings on both sides to squeeze the two sides of the pressure bar 13, so that the pressure bar 13 running through the openings on both sides undergoes elastic deformation and retracts into the terminal block 3. At this time, the terminal block 3 is pulled outward and then removed from the installation slot 8. When the maintenance is completed, the terminal block 3 is reinstalled in its original position. At this time, the elastic potential energy of the pressure bar 13 pushes the slide bar 201 out of the push block 2, thereby resetting the slide bar 201 and fastening the pressure bar 13 with the push block 2 to fix it, and then the terminal block 3 is installed in the installation slot 8 for use;

[0053] When the wires in the wiring port 301 need to be taken out at the same time, the push blocks 2 on both sides are pushed backward to make them slide in the opening, and the push blocks 2 drive the pressure rod 13 to slide inward of the movable groove. At this time, the pressure rod 13 pushes the buckle 11 inward synchronously, so that the buckle 11 cancels the buckle of the clamping rod 901, and the pressure plate 9 is released. The movable pressure rod 902 bounces upward under the action of the electromagnetic spring coil 9031, and the clamping plate 904 is loosened, making it easy to draw the wires out of the wiring port 301 at the same time. At this time, the staff can easily replace or check the wires in all the wiring ports 301. Secondly, the reset spring 202 is used to push the push rod 11 inward. Block 2 is reset. When the wiring in the wiring port 301 is taken out separately, the pressing rod 10 is pressed to make the buckle 11 move synchronously to the inside of the movable groove. Similarly, the buckle 11 cancels the buckling of the clamping rod 901. When the wiring in the wiring port 301 is maintained or replaced, the pressing plate 9 is pressed to press the movable pressing rod 902 downward and simultaneously press the electromagnetic spring coil 9031 downward. Then, the electromagnetic spring coil 9031 presses the sleeve rod 903 downward under the elastic potential energy, so that the clamping plate 904 under the sleeve rod 903 presses and clamps the wiring. At the same time, the buckle 11 re-fastens the fixed clamping rod 901, so that the wiring can be installed and used.

[0054] When the wiring is long and entangled with each other, the magnetorheological fluid is squeezed through the flow slot 304 and transported to the bellows 1201 by the spring and push plate in the installation box 1202. When the electromagnetic spring coil 9031 is connected to the conductive sheet 302, the current flowing through the electromagnetic spring coil 9031 will generate a magnetic field. At this time, the magnetic particles in the magnetorheological fluid will quickly arrange themselves along the direction of the magnetic field to form a chain or columnar structure, and the viscosity of the fluid will increase sharply, while the fluidity will decrease, causing the magnetorheological fluid to be converted into a Bingham fluid. At this time, the magnetorheological fluid in the form of a Bingham fluid in the bellows 1201 will support the buckle 11 to prevent The springs on both sides of the movable box 12 pull the buckle 11 inward under elastic potential energy, so that it cancels the fastening to the clamping rod 901. When the wiring in the wiring port 301 is powered off by pulling down the safety switch, the magnetic particles of the magnetorheological fluid lose the guidance of the magnetic field and return to the free-flowing Newtonian fluid state. At this time, the buckle 11 moves backward under the pull of the springs on both sides of the movable box 12, thereby canceling the fastening to the clamping rod 901, and then releasing the splint 904, so that the wiring can be freely pulled out, and at the same time, the pressure plate 9 pops up, so that the maintenance personnel can find the wiring port 301 corresponding to the wiring for quick positioning maintenance.

[0055] It should be noted that when the buckle 11 cancels the fastening of the card rod 901, since the electromagnetic spring coil 9031 is provided in the sleeve rod 903, the elastic potential energy of the electromagnetic spring coil 9031 is released, and at the same time, the clamping plate 904 is provided with a clamping tooth under the clamping plate 904, so that the clamping plate 904 can maintain a certain clamping degree on the wiring to prevent the wiring from escaping from the wiring port 301. When the pressure plate 9 is pushed upward, the sleeve rod 903 is driven to rise by the movable pressure rod 902 to cancel the clamping of the wiring by the clamping plate 904 to prevent the wiring from directly escaping from the wiring port 301 when there is no power. When the buckle 11 is fastened to the card rod 901, it is necessary to pull the push rod 10 to drive the buckle 11 to move forward to overcome the pulling force of the springs on both sides of the movable box 12 on the buckle 11.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
