Description

Technical Field

[0001] The invention relates to the technical field of electric energy meters, in particular to an intelligent electric energy meter with a remote safety management function. Background Art

[0002] An energy meter is an instrument used to measure electrical 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. When using an energy meter, please note that in the case of low voltage (not exceeding 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 a current transformer.

[0003] As an important tool for measuring electric energy, outdoor electric energy meters can perform stable metering work in the case of external rain due to their own sealing. However, due to the influence of rain, intuitive electric energy readings cannot be performed and manual wiping is required to ensure the cleanliness of the observation window. Manual operation is inconvenient and reduces the user experience. If a corresponding automatic cleaning mechanism is set, an additional power source mechanism needs to be set, which is costly. In addition, the electric energy meter generally does not have a corresponding protective structure. When subjected to a large external collision, it is easy to cause damage to the electric energy meter in the circuit, thereby reducing the safety of the electric energy meter and the safety level is low.

[0014] Furthermore, the crossbeam is connected with a strip groove matching it along the height direction of the outer wall of the frame, and the central axis of the second bevel gear and the screw shaft are connected by a fastening ring. As the water storage tank rotates downward to discharge the water and resets through the first spring rod, the screw shaft drives the cleaning brush on the crossbeam to perform reciprocating cleaning of the observation window.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the present invention, by setting a cleaning mechanism, rainwater from the outside can be collected into the water collection box, and the setting of the sliding inclined column on the water collection box can play a role of filtering and separation on the one hand, and can play a role of anti-blocking on the other hand, to prevent blockage from occurring at the notch. When water falls into the water storage tank, due to the continuous increase of gravity, the water storage tank rotates downward under the action of the rotating shaft, and after the water is discharged, due to the elastic recovery effect of the first spring rod, the rotating shaft rotates and resets, and through the action of mechanical transmission, the crossbeam on the lead screw nut moves up and down, so that the cleaning brush can automatically clean back and forth, so that the observation window will not be affected by rainwater, and no additional power source is required. The design is reasonable, the cost is low, and the degree of automation is high.

[0026] 2. The device of the present invention drives the first lifting column to move by the pressure when the magnetic protection component is hit by the outside world, and realizes the pressure unloading effect based on the magnetic resistance between the first magnet and the second magnet. In the process of the first magnet moving downward, the resistance part on it is constantly in contact with the baffle plate, and the resistance provided by the baffle plate is used to achieve the purpose of unloading the resistance part, thereby having a buffering effect on the first lifting column, effectively buffering and protecting the collision force when the circuit board collides in time, solving the problem that the electric energy meter is difficult to protect itself when it is accidentally hit by the outside world, and at the same time improving the safety performance of the device.

[0027] 3. During the descent process, the magnetic protection component will pull the buffer column upward, and use the buffer column to contact and push the second panel, thereby generating an opposite pushing force on the second panel, thereby achieving the purpose of using the second panel to provide buffering protection for the circuit board, further reducing the impact force of the circuit board and protecting the circuit board in the electric energy meter.

[0028] 4. The shock-absorbing protection component utilizes the effect of mechanical shock absorption to provide better protection for the second panel. By pulling the second swing rod outward, the force acting on the second panel is converted into the pushing force of the slider and the elastic potential energy of the third spring rod, thereby achieving better shock absorption. At the same time, the shock-absorbing protection component and the magnetic protection component are linked for protection, which can further improve the safety performance of the device.

DETAILED DESCRIPTION

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] According to an embodiment of the present invention, an intelligent electric energy meter has a remote safety management function.

[0043] Reference Manual Attached Figure 1 and attached Figure 2 , intelligent electric energy meter with remote safety management function, including:

[0044] A housing 1, the inner wall of which is provided with a meter 2, a circuit board 3 and a control switch 4 from top to bottom; a rear cover 5, which is connected to the housing 1 by locking and fixing with a positioning bolt; a front cover 6, which is connected to the edge of the rear cover 5 by plugging, and an observation window 7 is embedded and connected to the front cover 6;

[0045] The meter 2, circuit board 3 and control switch 4 are all detachably mounted on the housing 1. The reading on the meter 2 can be read through the observation window 7, so as to intuitively understand the power consumption in the current state. Positioning holes are also adaptively installed on the housing 1, so that it is convenient to connect with the external mounting plate by locking and fixing it through a bolt assembly.

[0046] like Figure 3 and Figure 4 As shown, the cleaning mechanism 8 includes a water collecting box 9 fixed to the bottom end of the front cover 6, and the notch on the water collecting box 9 is connected with sliding inclined columns 10 distributed equidistantly along the length direction of the front cover 6, and an inclined portion 11 disposed on the inner wall of the water collecting box 9 is provided below the sliding inclined column 10, and the bottom end of the inner wall of the water collecting box 9 is connected to a water storage tank 13 through a first spring rod 12, and one end of the water storage tank 13 is movably connected to the inner wall of the water collecting box 9 through a rotating shaft 14, and the cleaning mechanism 8 is used to reciprocate and clean the observation window 7;

[0047] The cleaning mechanism 8 converts the gravitational potential energy of the water into mechanical energy, thereby driving the cleaning brush 21 to clean the observation window 7, so as to avoid causing corresponding ambiguity to the observation window 7 in the case of external rain, making it impossible for personnel to clearly read the power consumption count. In addition, the sliding inclined column 10 on the water collection box 9 can play the role of filtering by the filter, and can also discharge particulate impurities to the outside through sliding friction. If only a single filter is used, the impurity particles are easily retained and blocked on the filter, thereby affecting the water collection effect, which is not conducive to the normal operation of the cleaning mechanism 8.

[0048] Specifically, both ends of the rotating shaft 14 pass through the water collecting box 9 and extend to the first bevel gear 16 inside the frame. The outer wall of the first bevel gear 16 is meshed with a second bevel gear 18 fixed on the screw shaft 17. The outer wall edge of the screw shaft 17 is spirally driven with a screw nut 19 connected to the ball. The screw nuts 19 are fixedly connected by a cross beam 20, and a cleaning brush 21 is detachably mounted on the cross beam 20.

[0049] The cross beam 20 is connected with a strip groove matched with it along the height direction of the outer wall of the frame. The central axis of the second bevel gear 18 and the screw shaft 17 are connected by a fastening ring. As the water storage tank 13 rotates downward to discharge the water and resets through the first spring rod 12, the screw shaft 17 drives the cleaning brush 21 on the cross beam 20 to reciprocate and clean the observation window 7. A guide port 22 that runs through the interior of the water collecting box 9 is opened on one side of the bottom end thereof.

[0050] Specifically, as the amount of water in the water tank 13 increases, the water tank 13 will rotate downward through the rotating shaft 14 at one end and with the rotating shaft 14 as the center, and then the rotating shaft 14 will drive the first bevel gears 16 at both ends to rotate, and through the gear meshing transmission, the screw nut 19 on the second bevel gear 18 will be driven to rotate, and then with the help of the spiral transmission, the screw nut 19 drives the cleaning brush 21 to move downward through the crossbeam 20 and clean the observation window 7 to prevent the ambiguity caused by rainwater from affecting the reading observation. When the water in the water tank 13 is discharged through the diversion port 22, due to the weight reduction and the elastic restoring force of the first spring rod 12 itself, the water tank 13 is reset. At this time, the rotating shaft 14 rotates in the opposite direction, and then through the action of mechanical transmission, the cleaning brush 21 moves upward for cleaning, so that the entire cleaning mechanism 8 performs reciprocating cleaning.

[0051] During the up and down movement of the beam 20, the strip grooves on the frame provide corresponding space for movement, while also preventing the beam 20 from deviating from its position during movement. The cleaning mechanism 8 does not rely on an additional power source for natural power rotation, and has a reasonable design, saves resources, and is environmentally friendly.

[0052] like Figure 5 As shown, the first bevel gear 16 and the second bevel gear 18 are bidirectionally synchronously arranged, which can provide a stable supporting force for the crossbeam 20, and the setting of the fastening ring can play a positioning and locking role between the center axis of the second bevel gear 18 and the screw shaft 17, so as to maintain the stability of the transmission.

[0053] In the present invention, by setting up a cleaning mechanism 8, rainwater from the outside can be collected into a water collecting box 9, and the setting of the sliding inclined column 10 on the water collecting box 9 can play a role of filtering and separation on the one hand, and can play a role of anti-blocking on the other hand, to prevent blockage from occurring at the slot. When water falls into the water storage tank 13, due to the continuous increase in gravity, the water storage tank 13 rotates downward under the action of the rotating shaft 14, and after the water is discharged, due to the elastic recovery effect of the first spring rod 12, the rotating shaft 14 rotates and resets, and through the action of mechanical transmission, the crossbeam 20 on the screw nut 19 moves up and down, and then the cleaning brush 21 performs automatic back and forth cleaning work, so that the observation window 7 will not be affected by rainwater, and no additional power source is required. The design is reasonable, the cost is low, and the degree of automation is high.

[0054] like Figure 2 , Figure 6 and Figure 7As shown, a protection mechanism 15 is installed between the shell 1 and the circuit board 3, and the protection mechanism 15 is used to perform collision protection work on the circuit board 3. The protection mechanism 15 includes a first panel 23 connected to the inner wall of the shell 1, and buffer columns 25 are installed on both sides of the first panel 23 through second spring rods 24. First lifting columns 27 and second lifting columns 28 are installed on both ends of the buffer columns 25 through first swing rods 26. The first lifting columns 27 and the second lifting columns 28 are respectively connected to magnetic protection components 29 and shock-absorbing protection components 30. The magnetic protection components 29 and the shock-absorbing protection components 30 are both installed with second panels 31 connected to the circuit board 3 on one end away from the first panel 23.

[0055] The protection mechanism 15 essentially performs shock absorption and buffering protection through the linkage of mechanical shock absorption, magnetic protection and buffering protection components. In addition, since the material of the circuit board 3 is not strong and hard, it is easy to be damaged when subjected to a large collision. Therefore, the patent sets a corresponding protection mechanism to improve the safety of the device. Since the technical solution of the patent only protects one side of the circuit board 3, the protection performance does not meet the comprehensive requirements. Therefore, buffer materials such as air cushions, sponge boards, etc. can be added around the circuit board 3, which can increase the comprehensive protection requirements around the circuit board 3.

[0056] like Figure 8 As shown, the magnetic protection component 29 includes a first magnet 32 ​​disposed at the bottom end of the first lifting column 27, and a second magnet 34 disposed on the inner wall of a sleeve 33 is provided directly below the first magnet 32. The first magnet 32 ​​and the second magnet 34 have opposite surfaces in the same direction with the same magnetic pole setting, and both ends of the first magnet 32 ​​are integrally connected with a resistance part 35. A baffle plate 37 is fixedly installed on the inner wall of the sleeve 33 by an elastic member 36, and the baffle plate 37 and the resistance part 35 are used in coordination with each other.

[0057] During the descent process, the magnetic protection component 29 will pull the buffer column 25 upward, and use the buffer column 25 to contact and push the second panel 31, thereby generating an opposite pushing force on the second panel 31, thereby achieving the purpose of using the second panel 31 to provide buffering protection for the circuit board 3, further reducing the impact force on the circuit board 3 and protecting the circuit board 3 in the electric energy meter.

[0058] like Fig. 9As shown, the shock-absorbing protection assembly 30 includes a second swing rod 38 placed on the second lifting column 28, one end of the second swing rod 38 is connected to a slider 40 inside the fixed block 39, one end of the slider 40 is connected to the side wall of the fixed block 39 through a third spring rod 41, and a strip groove is provided on the second swing rod 38 along the edge of the outer wall of the fixed block 39; wherein both ends of the first swing rod 26 are rotatably connected to the first lifting column 27 and the second lifting column 28 through a first movable shaft, and both ends of the second swing rod 38 are rotatably connected to the second lifting column 28 and the slider 40 through a second movable shaft.

[0059] The shock-absorbing protection component 30 utilizes the effect of mechanical shock absorption to provide better protection for the second panel 31. By pulling the second swing rod 38 outward, the force acting on the second panel 31 is converted into the pushing force of the slider 40 and the elastic potential energy of the third spring rod 41, thereby providing better shock absorption. At the same time, the shock-absorbing protection component 30 and the magnetic protection component 29 are linked for protection, which can further improve the safety performance of the device.

[0060] The device of the present invention drives the first lifting column 27 to move by the pressure when the magnetic protection component 29 is hit by the outside world. Based on the magnetic resistance between the first magnet 32 ​​and the second magnet 34, the pressure unloading effect is achieved by means of the principle of "like repels like and opposites attract". During the downward movement of the first magnet 32, the resistance part 35 thereon is constantly in contact with the baffle plate 37. The resistance provided by the baffle plate 37 is used to achieve the purpose of unloading the resistance part 35, thereby having a buffering effect on the first lifting column 27, effectively providing timely buffering protection for the collision force when the circuit board 3 is hit, solving the problem that the electric energy meter is difficult to protect itself when accidentally hit by the outside world, and at the same time improving the safety performance of the device.

[0061] The intelligent electric energy meter with remote safety management function also includes a data acquisition module 43 and a power failure monitoring unit 44 connected to the input end of the processor 42, and the output end of the processor 42 is connected to a display 45 and a storage module 46;

[0062] like Fig.10 As shown, the data acquisition module 43 is used to collect the power consumption of the electric energy meter and the working environment temperature data of the electric energy meter; the power failure monitoring unit 44 monitors power outages, power failures or power quality to determine whether the electric energy meter is in a normal working state, the data acquisition module 43 and the power failure monitoring unit 44 are connected to the processor 42 via 5G transmission, and the display 45 and the storage module 46 are connected to the processor 42 via wired transmission.

[0063] The quality requirements of electric energy refer to the standard GB / T12325-2008. When the electric energy does not meet the above standards, the power failure monitoring unit 44 can monitor whether the electric energy meter is still in a normal state, and the working data of the electric energy meter will be sent to the display 45 through the processor 42 for feedback and stored through the storage module 46. In this way, the working data of the electric energy meter can be observed through the remote management mode, thereby improving the safety of the device. GB / T12325-2008 "Power Quality Supply Voltage Deviation" applies to the deviation of the supply voltage from the system nominal voltage under normal operating conditions of the AC 50Hz power system.

[0064] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

Obviously, many modifications and changes can be made according to the content of this specification.
