Description
Technical Field
[0001] This utility model relates to the field of electricity meter technology, specifically to an antifreeze, highly stable electricity meter. Background Technology
[0002] Electricity meters, also known as energy meters, are mostly used to detect electrical energy. With the continuous development of science and technology, my country's electricity meter manufacturing has reached a considerable level and scale, and the types and lifespans of electricity meters are also diverse. Nowadays, semi-intelligent electricity meters are widely used in household, commercial, and industrial electricity use. However, existing electricity meters still have some defects and shortcomings in certain aspects:
[0003] An electricity meter, such as one with application number CN202110826333.X, includes a meter body; a lower positioning frame is fixedly connected to the lower surface of the meter body; a limiting lock plate is slidably connected to the front side plate of the lower positioning frame; an outer movable block is slidably connected to the front side of the lower positioning frame; and an inner movable conductor post is slidably connected to the rear side of the lower positioning frame. The meter body includes a meter connector located below the meter body, and the meter connector is a pentagonal conical structure made of copper. The lower positioning frame includes an outer positioning plate located on the front wall of the lower positioning frame; an inner positioning plate located behind the outer positioning plate; and a locking plate guide frame located on both sides of the front surface of the lower positioning frame, with a rectangular groove structure provided in the middle of the locking plate guide frame. The outer positioning plate includes an outer adjustment groove, which is formed on the outer positioning plate and has a trapezoidal cross-section. The inner positioning plate includes an inner adjustment groove, which is formed on the inner positioning plate and also has a trapezoidal cross-section.
[0004] The electricity meters mentioned in the above document do not have antifreeze treatment. Most existing electricity meters are installed outdoors. When the outdoor temperature is low, ice may condense on the meter wall due to the temperature difference between day and night and the moisture contained in the air. At this time, the internal components of the meter may freeze and crack, thus damaging the meter. When the ice melts, the water vapor produced cannot be discharged, which may affect the internal components.
[0005] The electricity meters mentioned in the above document have poor protection on the outside. Most existing electricity meters use bolt-fixed protective covers to protect the meter, and the fixing bolts can be opened by turning them with tools. At this time, the protective cover can be removed from the electricity meter, which poses a possibility that some outsiders may dismantle it and steal electricity.
[0006] Therefore, we proposed a freeze-resistant, highly stable electricity meter to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this utility model is to provide a freeze-resistant, highly stable electricity meter to solve the problems mentioned in the background art, such as damage to the electricity meter due to the lack of freeze protection and the poor protection effect of the outer end of the meter, which allows some outsiders to disassemble it and steal electricity.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a freeze-resistant, high-stability electricity meter, comprising a housing, hinges, a protective plate body, a shelf, and electrical components. Hinges are fixedly connected to both sides of the housing, and the protective plate body is nested inside the hinges. A shelf is fixedly connected inside the housing, and electrical components are fixedly connected to the upper surface of the shelf.
[0009] A heating tank is provided inside a housing, and a temperature sensor is fixedly connected to the bottom surface of the housing. The lower end of the temperature sensor is electrically connected to a heater. The heating tank is filled with heating liquid, and a drainage assembly is also provided inside the housing.
[0010] The protective plate groove is formed on the inner side of the protective plate body, and a protective component is provided on one side of the protective plate groove.
[0011] Furthermore, a first driving plate is nested on the upper surface of the placement rack, and a brush is fixedly connected to the side of the first driving plate. The brush is in contact with the inner wall of the housing. A motor is fixedly connected to the top of the inner part of the housing, and a rotating shaft is fixedly connected to the output end of the motor. The other end of the rotating shaft is fixedly connected to the upper surface of the first driving plate. The brush will brush away the water droplets formed by the water vapor generated when the inner wall of the housing is heated.
[0012] Furthermore, the drainage assembly includes a drainage channel, a plug, and a base plate. The drainage channel is located at the bottom of the housing, and the upper diameter of the drainage channel is smaller than the lower diameter. A plug is nested inside the upper end of the drainage channel. A connecting rod is fixedly connected to the bottom end of the plug, and the other end of the connecting rod is fixedly connected to the base plate. The drainage channel will discharge the water vapor it generates to the outside.
[0013] Furthermore, a placement groove is provided on the outer bottom of the housing, and an airbag is fixedly connected to the top of the placement groove. The other end of the airbag is fixedly connected to the upper surface of the base plate. Limiting rods are fixedly connected to both sides of the upper surface of the base plate, and the other end of the limiting rods is nested inside the bottom of the housing. The airbag will push the base plate to move.
[0014] Furthermore, the protective assembly includes an electric gear, a driven gear, and a rotating rod. The electric gear is nested in the groove of the protective plate, and the driven gear meshes with one side of the electric gear. The driven gear is also nested in the groove of the protective plate. Meanwhile, a rotating rod is fixedly connected to the outside of the driven gear. The driven gear will drive the rotating rod to rotate under the action of the electric gear.
[0015] Furthermore, a limiting sleeve is fixedly connected to the groove of the protective plate, and an insert rod is nested inside the limiting sleeve on the other side. One end of the insert rod is nested inside the locking sleeve, while the locking sleeve is fixedly connected to the groove of the protective plate on the other side. The other end of the insert rod is fixedly connected to a second driving plate, and a driving block is nested inside the second driving plate. The other end of the driving block is fixedly connected to a rotating rod. When the insert rod enters the locking sleeve, it will fix the two protective plate bodies.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This antifreeze, high-stability electricity meter is equipped with a drainage component. When ice forms on the outside of the meter, the temperature sensor will activate the heater to melt the ice. As the ice melts, a lot of water vapor may appear inside the casing. At this time, the motor can be activated to brush away the water droplets formed by the water vapor through the brush. The water droplets can drip to the bottom of the casing. If the plug is not used to block the top of the drainage channel, the liquid dripping from the casing can be discharged outward through the drainage channel. This structure reduces the possibility of the meter freezing and being damaged in low-temperature environments to a certain extent. At the same time, it automatically drains the liquid generated when the casing is heated, reducing the possibility of internal liquid damaging electrical components.
[0018] 2. This antifreeze, high-stability electricity meter is equipped with protective components. When the user closes the protective plate body, the electric gear can be activated through the control panel. When the electric gear rotates, the second drive plate drives the plug rod to move within the limit sleeve until the plug rod enters the locking sleeve, locking and fixing the two protective plate bodies. To a certain extent, it can be fixed inside the housing, so that the fixing structure is not exposed, reducing the possibility of external personnel removing the meter's protective mechanism to steal electricity.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-5 This utility model provides a technical solution: a freeze-resistant, high-stability electricity meter, comprising a housing 1, a hinge 2, a protective plate body 3, a heating groove 4, a temperature sensor 5, a heater 6, a placement rack 7, electrical components 8, a motor 9, a rotating shaft 10, a first driving plate 11, a brush 12, a drainage groove 13, a plug 14, a connecting rod 15, a base plate 16, a placement groove 17, an airbag 18, a limiting rod 19, a protective plate groove 20, an electric gear 21, a driven gear 22, a rotating rod 23, a second driving plate 24, a driving block 25, a limiting sleeve 26, an insertion rod 27, and a locking sleeve 28.
[0027] In this embodiment:
[0028] Hinges 2 are fixedly connected to both sides of the housing 1, and a protective plate body 3 is nested inside the hinges 2. A storage rack 7 is fixedly connected inside the housing 1, and an electrical component 8 is fixedly connected to the upper surface of the storage rack 7.
[0029] Heating tank 4 is located inside housing 1, and temperature sensor 5 is fixedly connected to the bottom surface of housing 1. Temperature sensor 5 is electrically connected to heater 6 at the lower end of temperature sensor 5. Heating liquid is provided inside heating tank 4, and drainage assembly is also provided inside housing 1.
[0030] The protective plate groove 20 is formed on the inner side of the protective plate body 3, and a protective component is provided on one side of the protective plate groove 20.
[0031] A first driving plate 11 is nested and connected to the upper surface of the placement rack 7, and a brush 12 is fixedly connected to the side of the first driving plate 11. The brush 12 is in contact with the inner wall of the housing 1. A motor 9 is fixedly connected to the top of the inside of the housing 1, and a rotating shaft 10 is fixedly connected to the output end of the motor 9. The other end of the rotating shaft 10 is fixedly connected to the upper surface of the first driving plate 11. The drainage assembly includes a drainage channel 13, a plug 14, and a bottom plate 16. The drainage channel 13 is opened at the bottom of the housing 1, and the upper diameter of the drainage channel 13 is small. A plug 14 is nested inside the upper end of the drain groove 13, and a connecting rod 15 is fixedly connected to the bottom end of the plug 14. The other end of the connecting rod 15 is fixedly connected to the bottom plate 16. A placement groove 17 is opened on the outer side of the bottom of the housing 1. An airbag 18 is fixedly connected to the top of the placement groove 17. The other end of the airbag 18 is fixedly connected to the upper surface of the bottom plate 16. Limiting rods 19 are fixedly connected to both sides of the upper surface of the bottom plate 16. The other end of the limiting rods 19 is nested inside the bottom of the housing 1.
[0032] according to Figure 1 , Figure 2 and Figure 3 When ice forms on the outside of the meter, the temperature sensor 5 is activated and the heater 6 is activated. The heater 6 heats the liquid inside the heating tank 4, thereby raising the temperature of the casing 1 and melting the ice on the outside of the meter. When the ice melts, a lot of water vapor may appear inside the casing 1. At this time, the motor 9 can be activated. When the motor 9 is running, it drives the first driving plate 11 to rotate along the placement frame 7 through the rotating shaft 10. During the rotation, the first driving plate 11 brushes away the water droplets formed by the water vapor generated when the inner wall of the casing 1 is heated through the brush 12. The water droplets can drip onto the bottom of the casing 1. When the temperature of the casing 1 rises, the air bladder 18 in the placement tank 17 expands due to heat. At this time, the air bladder 18 pushes the bottom plate 16 downward to move. Under the action of the limiting rod 19, the bottom plate 16 drives the plug 14 to move downward through the connecting rod 15 to limit the movement. At this time, the plug 14 does not block the top of the drain tank 13, and the liquid dripping from the casing 1 can be discharged outward through the drain tank 13.

The electric gear 21 is nested in the groove 20 of the protective plate, and the driven gear 22 meshes with one side of the electric gear 21. The driven gear 22 is also nested in the groove 20 of the protective plate, and the rotating rod 23 is fixedly connected to the outside of the driven gear 22. A limiting sleeve 26 is fixedly connected to the groove 20 of the protective plate, and a plug rod 27 is nested inside the limiting sleeve 26 on the other side. One end of the plug rod 27 is nested in the engaging sleeve 28, and the engaging sleeve 28 is fixedly connected to the groove 20 of the protective plate on the other side. The other end of the plug rod 27 is fixedly connected to a second driving plate 24, and a driving block 25 is nested inside the second driving plate 24. The other end of the driving block 25 is fixedly connected to the rotating rod 23.
[0034] according to Figure 1 , Figure 4 and Figure 5 When the user closes the protective plate body 3, the electric gear 21 can be activated through the control panel. When the electric gear 21 rotates, it will synchronously drive the driven gear 22 to rotate. When the driven gear 22 rotates, it will drive the rotating rod 23 to rotate. When the rotating rod 23 rotates, it will drive the driving block 25 to slide in the second driving plate 24. The second driving plate 24 will drive the insertion rod 27 to move within the limiting sleeve 26 until the insertion rod 27 enters the locking sleeve 28 and locks the two protective plate bodies 3 in place.
