Description

Technical Field

[0001] The present application relates to the technical field of electric meters, and in particular to a smart electric meter. Background Art

[0002] With the rapid development of science and technology and the continuous changes in the global energy structure, the construction of smart grids has become an important trend in the power industry. As the core component of the smart grid, smart meters undertake the important tasks of real-time monitoring, automatic recording and analysis of electricity consumption data. They can monitor electricity consumption data in real time and transmit the data to the power company's data center, providing strong support for the power company's electricity management and decision-making. Electricity meters are usually installed on the outer walls of houses, especially near the entrance of the house and in areas that are convenient for power supply. This installation method is convenient for power workers to read meters and perform maintenance work, and it also complies with power safety regulations. However, while installing it outside the house brings convenience, it also brings inevitable disadvantages.

[0003] The existing technology still has the following problems: 1. Traditional electric meters installed outdoors are easily affected by the weather. The outdoor environment is changeable, and the electric meter may be affected by natural factors such as wind and rain, resulting in inaccurate meter readings or damage. For example, electric meters usually have a ventilation structure. In windy and rainy weather, rainwater can easily enter the inside of the electric meter under the action of wind, which may damage the electronic components inside the electric meter, thereby affecting its normal operation. At the same time, rainwater mixed with dust adheres to the outer surface of the electric meter box, making it difficult to see the specific degree of the electric meter. The outer box of the electric meter needs to be opened, or the electric meter box needs to be wiped, which affects the work efficiency of the staff.

[0004] 2. Traditional electric meters are mostly installed outdoors. If the installation location is inappropriate or the protective measures are insufficient, certain safety hazards may occur. For example, the meter box may be damaged by external impact. In addition, the meter is fixed to the wall by bolts, which makes it inconvenient to disassemble the meter as a whole. At the same time, the meter needs regular maintenance and inspection to ensure its normal operation and safety. If it is inconvenient to disassemble, it will increase the difficulty and time cost of maintenance personnel, thereby affecting maintenance efficiency and effectiveness. In emergency situations, such as circuit failure or damage to electrical equipment, if the meter box is inconvenient to disassemble, it may delay maintenance time and increase losses and risks.

[0016] The technical solution provided by this application has at least the following technical effects or advantages: 1. Due to the use of ventilation and dustproof components, the problem that the traditional electric meter installed outdoors is easily affected by the outside weather is effectively solved. The outdoor environment is changeable, and the electric meter may be affected by natural factors such as wind and rain, which may cause the electric meter reading to be inaccurate or damaged. For example, the electric meter usually has a ventilation structure. In windy and rainy weather, rainwater can easily enter the inside of the electric meter under the action of wind, so that the electronic components inside the electric meter may be damaged, thereby affecting its normal operation. At the same time, rainwater mixed with dust adheres to the outer surface of the electric meter box, resulting in unclear readings of the electric meter. The outer box of the electric meter needs to be opened, or the electric meter box body needs to be wiped, which affects the work efficiency of the staff. The present invention can prevent rainwater from bringing dust into the electric meter under the action of wind in rainy weather through the ventilation and dustproof components, avoiding damage to the electronic components inside the electric meter. After the rain stops, the electric meter box continues to maintain a ventilation state. At the same time, the perspective window on the outer surface of the electric meter box can be wiped in rainy weather to keep the perspective window of the electric meter box clean, which is convenient for the staff to read the power consumption, thereby improving the staff efficiency.

[0017] 2. The use of flexible connection components effectively solves the problem that most traditional electric meters are installed outdoors. If the installation position is improper or the protective measures are insufficient, certain safety hazards may occur. For example, the meter box may be damaged by external impact. In addition, the meter is fixed to the wall by bolts, which makes it inconvenient to disassemble the meter as a whole. At the same time, the meter needs regular maintenance and inspection to ensure its normal operation and safety. If it is inconvenient to disassemble, it will increase the operating difficulty and time cost of the maintenance personnel, thereby affecting the maintenance efficiency and effect. In emergency situations, such as circuit failure or damage to electrical equipment, if the meter box is inconvenient to disassemble, it may delay the maintenance time, increase losses and risks. The present invention can reduce the damage to the meter when the meter collides through the flexible connection component. At the same time, the meter can be quickly disassembled during maintenance, and has an anti-falling alarm effect. No alarm will be generated during normal disassembly, and an alarm will be generated when it falls off unplanned, reminding the staff to perform maintenance in time. At the same time, the buffer mechanism greatly reduces the possibility of the meter falling off during collision, and improves the service life of the meter. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting plate 3 and the fixing plate 4 can be quickly disassembled through the flexible connecting component 6, which is convenient for timely maintenance. At the same time, the flexible connecting component 6 can be buffered when the outside of the meter box 1 is hit. The ventilation and dustproof component 5 can be used to clean the perspective window on the outer surface of the meter box 1 in rainy weather, which is convenient for observing the readings on the display of the component assembly 2 for the staff to record data. At the same time, the vent is blocked in rainy weather to prevent rainwater from entering the inner cavity of the meter box 1 and avoid the component assembly 2 from being affected by rainwater and causing a short circuit.

[0023] See also Figure 2 and Figure 3 As shown, the ventilation and dustproof assembly 5 includes a water collecting box 51, a pressure rod 52 is fixedly connected to the bottom end of the water collecting box 51, a dustproof mechanism 53 is arranged at the bottom end of the pressure rod 52, a cleaning mechanism 54 is arranged on the outer surface of the meter box body 1, ventilation holes are opened on both sides of the meter box body 1, ventilation grilles 55 are fixedly installed at the ventilation holes on both sides of the meter box body 1, a dust box 56 is slidably connected to the inner cavity of the meter box body 1, the water collecting box 51 is slidably connected to the connecting plate 3, and the outer surfaces of the water collecting box 51 and the connecting plate 3 are tightly fitted, the pressure rod 52 is slidably connected to the meter box body 1, and when it rains, the water collecting box 51 and the connecting plate 3 are The inner cavity formed on the outer surface of the connecting plate 3 collects rainwater, which increases the overall weight of the water collecting box 51. The increased weight of the water collecting box 51 causes the pressure rod 52 to slide down in the inner cavity of the meter box 1. The movement of the pressure rod 52 drives the dustproof mechanism 53 to move downward. At this time, the dustproof mechanism 53 blocks the vent. At the same time, the downward movement of the dustproof mechanism 53 drives the cleaning mechanism 54 to clean the perspective window on the outer surface of the meter box 1. The ventilation grille 55 is used for dust-proof ventilation. The dust box 56 is used to collect dust near the vent, which is convenient for timely cleaning, reduces pollution to the inside of the meter box 1, and prolongs the service life of the entire meter.

When it rains, the weight of the water collection box 51 increases, driving the pressure rod 52 to squeeze the movable frame 531, and at this time, the movable frame 531 slides down the inner wall of the meter box 1, and the movable frame 531 The downward movement of the movable frame 531 drives the movable frame 531 to slide on the first slide bar 533. At this time, the movable frame 531 is close to the support plate 535 and the first slide bar 533 is compressed. When the water collecting box 51 is full of water, the first button 536 contacts the pressure block 532 and presses the first button 536. The length of the pressure block 532 can be adjusted in actual use to ensure that the pressure block 532 can press the first button 536 under the gravity of the water collecting box 51 and rainwater, so that the first button 536 controls the cleaning mechanism 54 to clean the perspective window on the outer surface of the meter box 1, so that the staff can quickly read the electricity consumption of the meter after rainy weather. The downward movement of the movable frame 531 drives the first shielding plate 537 to move downward, thereby blocking the vent to prevent rain Water flows into the inner wall of the meter box 1 from the ventilation grille 55. At the same time, when the first baffle plate 537 moves downward, the first baffle plate 537 drives the driving block 538 to move downward. The driving block 538 moves downward and drives the driving rod 5311 on the slide 5310 to rotate in the inner cavity of the driving groove 539, so that the slide 5310 moves outward in the inner cavity of the meter box 1. At this time, the second baffle plate 5312 moves outward in the inner cavity of the meter box 1. The second baffle plate 5312 better blocks the outer surface of the ventilation grille 55, plays the role of an eave, and reduces the possibility of rainwater entering the inner cavity of the ventilation grille 55.

At the same time, the vents are shielded in rainy weather to prevent rainwater from entering the inner cavity of the meter box 1 and to prevent the component assembly 2 from being affected by rainwater and causing a short circuit. In rainy weather, the inner cavity formed by the water collecting box 51 and the outer surface of the connecting plate 3 collects rainwater, which increases the overall weight of the water collecting box 51. The increase in the weight of the water collecting box 51 causes the pressure rod 52 to slide down in the inner cavity of the meter box 1. The movement of the pressure rod 52 drives the dustproof mechanism 53 to move downward. At this time, the dustproof mechanism 53 shields the vents. At the same time, the dustproof mechanism 53 moves downward. The cleaning mechanism 54 is driven to clean the perspective window on the outer surface of the meter box 1. The ventilation grille 55 is used for dust-proof ventilation. The dust box 56 is used to collect dust near the vent, which is convenient for timely cleaning, reduces the pollution to the inside of the meter box 1, and prolongs the service life of the meter as a whole. By fixing the anti-drop plug 61 between the limit blocks 64, the connecting plate 3 is fixed as a whole to the outer surface connected to the fixing plate 4, so that the anti-drop plug 61 is taken out from the middle of the limit block 64 when disassembly is required, so as to achieve the effect of quick disassembly. At the same time, in the case of unplanned disassembly, The alarm mechanism 66 can give an alarm in time to prevent the meter box 1 from falling off. The elastic force of the fourth spring 65 drives the limit block 64 to limit the anti-falling plug 61, thereby realizing the connection between the anti-falling plug 61 and the connecting seat 62, that is, the connection between the connecting plate 3 and the fixing plate 4, and at the same time achieving the effect of starting disassembly. The buffer mechanism 67 can reduce the damage to the meter box 1 when an external collision occurs to the meter box 1. The flexible buffering enables the equipment to have a good buffering effect during a collision, thereby reducing the probability of the meter box 1 falling off and reducing the damage to the meter box 1 when it is hit.
