Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and more specifically, to a moisture-proof electricity meter. Background Technology

[0002] An electricity meter, usually referring to an energy meter, is an instrument used to measure electrical energy consumption. It is installed in a circuit and records the amount of electricity used. Electricity meters are generally not used independently; usually, multiple electricity meters are housed in a meter box and used in conjunction with circuit breakers, fuses, and other power distribution components. Therefore, broadly speaking, a meter box that integrates electricity meters and related power distribution components can also be called an electricity meter.

[0003] Because meter boxes contain many integrated power distribution components, they generate a lot of heat. In southern coastal areas or in factories and workshops with high humidity and temperature, the air is hot and humid. Therefore, many meter boxes are equipped with heat dissipation devices, usually fans, for ventilation and heat dissipation. At the same time, due to the high humidity, some meter boxes also have water-absorbing filters at the air inlet to keep the inside of the meter box dry and extend the service life of the power distribution components. However, in order not to affect the ventilation effect of the air inlet, the thickness of the water-absorbing filter is generally small, and the amount of water it can absorb is relatively small. Therefore, the water-absorbing filter needs to be replaced frequently, making it cumbersome to use. Utility Model Content

[0004] The present invention provides a moisture-proof electricity meter, which aims to solve the following problem: the existing water-absorbing filter screens used in electricity meter boxes to keep the meter box dry for a long time are generally thin and can absorb relatively little water in order not to affect the ventilation effect. Therefore, the water-absorbing filter screens need to be replaced frequently, which is quite cumbersome.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a moisture-proof electricity meter, comprising: an electricity meter box, the electricity meter box including a shell, ventilation openings provided on both sides of the shell, a heat dissipation mechanism provided inside the shell, the heat dissipation mechanism including two symmetrically arranged partitions, the partitions being parallel to the side walls of the shell, and through holes being provided on the partitions, with a fan provided on one of the through holes;

[0006] The housing is equipped with a moisture-proof mechanism, which includes several water-absorbing components arranged vertically, with the water absorption capacity of each component increasing sequentially from bottom to top. The water-absorbing components are adapted to the vents. The moisture-proof mechanism also includes a support component, which includes several sets of support plates rotatably mounted on the inner wall of the housing. The connection between the support plate and the inner wall of the housing is provided with an elastic support component, and the support plate is used to support the water-absorbing components.

[0007] In a preferred embodiment, a connecting rod is rotatably arranged between several support plates located on the same side.

[0008] In a preferred embodiment, the two partitions are respectively enclosed by the two side walls of the shell to form a cavity, and the through holes are adapted to the corresponding vents. The vents are provided with dust covers, and several water absorption components are respectively located in the corresponding cavities.

[0009] In a preferred embodiment, guide strips are provided on both inner walls of the housing, and a guide groove is provided on the side of the water absorption component near the corresponding vent, the guide groove being adapted to the guide strip.

[0010] In a preferred embodiment, an upper sealing plate is provided at the top of the housing, and a lower sealing plate is provided at the bottom of the housing. One end of the lower sealing plate is rotatably connected to the housing, and an elastic tensioning component is provided at the connection between the lower sealing plate and the housing.

[0011] In a preferred embodiment, the front of the housing is open, and a door is rotatably provided on the front of the housing, with an observation window provided on the door.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a heat dissipation mechanism, enables the meter box to maintain a suitable temperature for a long time, effectively extending the service life of the power distribution components.

[0014] This invention, by setting up a moisture-proof mechanism, can automatically replace the water-absorbing component, significantly reducing the frequency and difficulty of manual replacement of the water-absorbing component, allowing the meter box to remain dry for a long time, and further improving the service life of the power distribution components.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 6 A moisture-proof electric meter includes: an electric meter box 1, the electric meter box 1 includes a shell 11, ventilation openings 12 are provided on both sides of the shell 11, a heat dissipation mechanism 2 is provided inside the shell 11, the heat dissipation mechanism 2 includes two symmetrically arranged partitions 21, the partitions 21 are parallel to the two side walls of the shell 11, and through holes are opened on the partitions 21, and a fan 22 is provided on one of the through holes.

[0024] The housing 11 is provided with a moisture-proof mechanism 3, which includes several water-absorbing components 31 arranged vertically, and the water absorption capacity of a single water-absorbing component 31 increases sequentially from bottom to top. The water-absorbing components 31 are adapted to the vent 12. The moisture-proof mechanism 3 also includes a support component 32, which includes several sets of support plates 321 rotatably mounted on the inner wall of the housing 11. The connection between the support plate 321 and the inner wall of the housing 11 is provided with an elastic support component 322. The support plate 321 is used to support the water-absorbing components 31.

[0025] It should be noted that the absorbent material in the absorbent component 31 may be absorbent silicone or other materials with similar functions known to those skilled in the art.

[0026] In this embodiment, the specific implementation scenario is as follows: When using the meter box, by starting the fan 22, air can be drawn into the housing 11 through the ventilation port 12 on one side, thereby generating a flowing airflow in the meter box 1, which carries away the heat generated by the power distribution components through the ventilation port 12 on the other side and discharges it from the housing; furthermore, by setting up several water-absorbing components 31 supported by the support component 32, and arranging the several water-absorbing components 31 in order of increasing water absorption capacity from bottom to top, the water-absorbing components 31, whose weight increases after absorbing water, press all the support plates 321 downward and rotate. When the water-absorbing components 31 reach or approach their maximum water absorption capacity, the rotation angle of the support plate 321 is just enough to cause the water-absorbing component 31 at the bottom to fall off and be discharged from the housing 11. At the same time, the previous water-absorbing component 31 falls onto the support plate 321 at the bottom, thereby automatically completing the replacement of the water-absorbing component 31.

[0027] Refer to the instruction manual appendix Figure 5 and Figure 6 In this embodiment, several support plates 321 located on the same side are rotatably connected by connecting rods 323.

[0028] It should be noted that the spacing between the two adjacent support plates 321 used to support the two adjacent water absorption components 31 is adapted to the height of the corresponding water absorption component 31, and a suitable redundant space is reserved.

[0029] Refer to the instruction manual appendix Figure 2 and Figure 3 In this embodiment, the two partitions 21 are respectively enclosed by the two side walls of the housing 11 to form a cavity, and the through holes are adapted to the corresponding vents 12. The vents 12 are provided with dust covers, and several water absorption components 31 are respectively located in the corresponding cavities.

[0030] It should be noted that the dust cover and the housing 11 are detachably connected.

[0031] Refer to the instruction manual appendix Figure 3 and Figure 5 In this embodiment, guide strips 16 are provided on both inner walls of the housing 11, and guide grooves are provided on the side of the water absorption assembly 31 near the corresponding vent 12. The guide grooves are adapted to the guide strips 16.

[0032] It should be noted that the guide groove and guide bar 16 are technologies well known to those skilled in the art, and will not be described in detail in this utility model.

[0033] Refer to the instruction manual appendix Figure 5 and Figure 6In this embodiment, an upper sealing plate 13 is provided on the top of the housing 11, and a lower sealing plate 14 is provided on the bottom of the housing 11. One end of the lower sealing plate 14 is rotatably connected to the housing 11, and an elastic tensioning component 15 is provided at the connection between the lower sealing plate 14 and the housing 11.

[0034] It should be noted that both the upper sealing plate 13 and the lower sealing plate 14 are detachably connected to the housing 11, and the elastic tension assembly 15 can be a tension spring assembly or other devices with similar functions known to those skilled in the art.

[0035] Furthermore, a collection box can be provided below the lower sealing plate 14 to collect the used water absorption component 31. This is a technology well known to those skilled in the art and will not be described in detail in this utility model.

[0036] Refer to the instruction manual appendix Figure 1 In this embodiment, the front of the housing 11 is open, and a door 17 is rotatably provided on the front of the housing 11, with an observation window 18 provided on the door 17.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
