[0049] The electric meter box with waterproof and moisture-proof functions has the water blocking device 8 and the waterproof coating arranged on the outer side of the box body 1 to prevent water from entering the inside of the box body 1, thereby improving the safety of the equipment, the dehumidification modes are various, the moisture absorbing part 5 is used for absorbing and removing the moisture in the box body 1, the heat drying part 6 is used for heating and removing the moisture in the box body 1, and the air drying part 2 is used for blowing and removing the moisture in the box body 1, the moisture absorbing part 5, the heat drying part 6 and the air drying part 2 absorb, heat and blow to remove the moisture in the box body 1, thereby greatly improving the dehumidification effect, the water blocking device 8, the waterproof coating, the moisture absorbing part 5, the heat drying part 6 and the air drying part 2 are interrelated and jointly act, thereby greatly improving the waterproof and moisture-proof effect of the electric meter box, improving the safety of the equipment, and prolonging the service life of the electric wire in the box body 1, the included angle α between the first water blocking plate 81 and the second water blocking plate 82 is arranged to completely cover the box body 1 to prevent water from entering the inside of the box body 1 and does not affect the heat dissipation of the box body 1, the telescopic assembly 7 can press and start the heat drying part 6 to dehumidify the inside of the box body 1, thereby improving the dehumidification effect and reducing unnecessary loss.

[0050] Specifically, as shown in the figure, Figure 1 and Figure 3 the included angle α between the first water blocking plate 81 and the second water blocking plate 82 satisfies 135°≤α≤150°. The arrangement can completely cover the box body 1 to prevent water from entering the inside of the box body 1 and does not affect the heat dissipation of the box body 1. If the included angle is too small, the box body 1 cannot be completely covered to prevent water from entering the inside of the box body 1, and if the included angle is too large, the heat dissipation of the box body 1 is affected.

[0051] More specifically, the first water blocking plate 81 and the second water blocking plate 82 are arranged above the box body 1,

[0052] The connection between the first water baffle 81 and the second water baffle 82 is arranged towards the side away from the box 1. This arrangement can completely cover the box 1 to prevent water from entering the inside of the box 1, and does not affect the heat dissipation of the box 1.

[0053] Specifically, as shown in Figure 1 and Figure 3 , the water baffle device 8 further comprises a third water baffle 83 and a fourth water baffle 84, the third water baffle 83 and the fourth water baffle 84 are symmetrically arranged on the left and right sides of the box 1, and the third water baffle 83 and the fourth water baffle 84 are arranged towards the lower side of the box 1.

[0054] This arrangement further prevents water from entering the inside of the box 1 outside the box 1, thereby improving the waterproof effect of the electric meter box.

[0055] Specifically, as shown in Figure 1 , the box 1 comprises an upper panel 11, a lower panel 12, a left panel 13, a right panel 14 and a rear panel 15.

[0056] Specifically, as shown in Figure 4 , the moisture absorption part 5 comprises a high molecular water absorption resin 54 and a first shell 51, and the high molecular water absorption resin 54 is uniformly and fixedly arranged in the inside of the first shell 51.

[0057] The high molecular water absorption resin 54 has a very strong water absorption effect and can absorb the moisture in the inside of the box 1. The weight of the high molecular water absorption resin 54 will increase after absorbing water.

[0058] More specifically, the number of the high molecular water absorption resin 54 is not limited.

[0059] More specifically, as shown in Figure 5 , air inlet holes 511 and air outlet holes 512 are arranged on the first shell 51.

[0060] More specifically, as shown in Figure 4 and Figure 5 , the inside of the first shell 51 is a hollow structure, a partition assembly 52 is arranged in the inside of the first shell 51, the partition assembly 52 comprises a second partition 521 and a third partition 522, the partition assembly 52 divides the inside of the first shell 51 into four first cavities 53, and the high molecular water absorption resin 54 is arranged in the inside of the first cavity 53.

[0061] More specifically, as shown in Figure 5 , air flow holes 523 are arranged on the partition assembly 52. This arrangement facilitates the air flow in the inside of the first cavity 53.

[0062] Specifically, the heated tube 6 includes a self-heating bag 63 and a second housing 61, with the self-heating bag 63 fixed inside the second housing 61.

[0063] This setup has two advantages. First, the self-heating bag 63 generates heat when activated, which heats up and removes moisture from the cabinet 1, improving the dehumidification effect. Second, the heat source for heating the heat-generating tube 6 is provided by the exothermic reaction of the supersaturated solution in the self-heating bag 63, eliminating the need for additional heating components and reducing energy consumption.

[0064] Specifically, the self-heating bag 63 contains a supersaturated solution, such as... Figure 6 As shown, a button device 64 is provided on the self-heating bag 63, and the button device 64 is in contact with the supersaturated solution.

[0065] When activated, simply press button 64. The supersaturated solution in the self-heating bag 63 will generate an exothermic reaction under the action of button 64, eliminating the need for additional heating components and reducing power consumption.

[0066] Furthermore, when the internal temperature of the housing 1 is high, the supersaturated solution in the self-heating bag 63 absorbs heat and changes from solid to liquid, which helps dissipate heat from the housing 1. The self-heating bag 63 is reusable, saving resources.

[0067] Specifically, the supersaturated solution is not limited. Preferably, in this embodiment, the supersaturated solution can be a supersaturated sodium acid solution. Supersaturated sodium acid solution is harmless to the human body.

[0068] More specifically, such as Figure 7 As shown, the interior of the second housing 61 is a hollow structure, forming a second cavity 62. A self-heating bag 63 is installed inside the second cavity 62.

[0069] More specifically, such as Figure 6 As shown, a partition strip 65 is provided on the self-heating bag 63, which divides the self-heating bag 63 into four independent supersaturated solution holding chambers.

[0070] Specifically, such as Figure 7 As shown, mounting holes 66 are provided on the second housing 61, such as... Figure 2 As shown, the button device 64 is installed in the mounting hole 66, and the button device 64 passes through the mounting hole 66 and is disposed on the outside of the moisture-absorbing part 5.

[0071] This design facilitates the installation of the button device 64 on the one hand, and exposes the button device 64 on the other hand, thereby facilitating the activation of the supersaturated solution in the self-heating bag 63 to carry out an exothermic reaction.

[0072] Specifically, such asFigure 1 、 Figure 2 and Figure 3 As shown in the drawings, the heat-drying part 6 is arranged directly above the moisture-absorbing part 5.

[0073] On one hand, the heat-drying part 6 can heat and remove the moisture in the box 1, and on the other hand, the heat-drying part 6 can heat and remove the moisture absorbed by the polymer water-absorbing resin 54 in the moisture-absorbing part 5, thereby increasing the water-absorbing capacity and service life of the polymer water-absorbing resin 54 in the moisture-absorbing part 5.

[0074] Specifically, the air-drying part 2 comprises a first fan 21, a second fan 22 and a third fan 23, which are evenly arranged in the interior of the box 1.

[0075] This arrangement facilitates the air-drying part 2 to blow and remove the moisture in the box 1, thereby improving the dehumidification effect, and is also conducive to heat dissipation and dust removal in the box 1.

[0076] Specifically, a retractable assembly 7 is arranged in the interior of the box 1, which is used to start the heat-drying part 6.

[0077] The retractable assembly 7 is associated with the heat-drying part 6 and cannot be separated, and the heat-drying part 6 can be pressed to start the dehumidification of the interior of the box 1 through the retractable assembly 7, which can improve the dehumidification effect and reduce unnecessary loss.

[0078] Specifically, a telescopic adjusting device 4 is arranged on the box 1, which is used to adjust the extension or retraction of the retractable assembly 7.

[0079] The telescopic adjusting device 4, the retractable assembly 7 and the heat-drying part 6 are associated with each other and cannot be separated, and the telescopic adjusting device 4 can control the extension of the retractable assembly 7 to start the dehumidification of the interior of the box 1 through the heat-drying part 6, thereby improving the dehumidification effect.

[0080] The air inlet hole 511 is arranged at the rear left position of the first shell 51, which makes the air entering the interior of the first shell 51 necessarily enter the interior of the first cavity 53 at the rear left position first, so that the polymer water-absorbing resin 54 in the first cavity 53 at the rear left position absorbs the moisture first, and thus the weight of the polymer water-absorbing resin 54 in the first cavity 53 at the rear left position begins to increase first, thereby causing the moisture-absorbing part 5 to be unbalanced.

[0081] The moisture absorption part 5, the telescopic adjusting device 4, the telescopic assembly 7 and the heat drying part 6 are associated with each other and jointly act, when the moisture absorption part 5 starts to absorb the moisture in the box 1, the moisture absorption part 5 will be unbalanced, the telescopic adjusting device 4 detects the unbalance of the moisture absorption part 5, the telescopic adjusting device 4 adjusts the current size of the telescopic assembly 7 to adjust the telescopic assembly 7 to extend, the telescopic assembly 7 extends to press the button device 64 to start the heat drying part 6 to dehumidify the inside of the box 1.

[0082] The moisture absorption part 5, the telescopic adjusting device 4, the telescopic assembly 7 and the heat drying part 6 are associated with each other and cannot be separated, and play multiple roles. First, the moisture absorption part 5 and the heat drying part 6 jointly remove the moisture in the box 1 to improve the dehumidification effect; second, the heat source of the heat drying part 6 is provided by the heat release of the supersaturated solution in the self-heating bag 63, without additional heating components, reducing power consumption; third, the heat drying part 6 is started at the same time when the moisture absorption part 5 starts to absorb the moisture in the box 1, which can increase the water absorption capacity and service life of the polymer water absorption resin 54 of the moisture absorption part 5; fourth, when the internal temperature of the box 1 is relatively high, the supersaturated solution in the self-heating bag 63 will absorb heat to change from solid to liquid, which is beneficial to heat dissipation of the box 1.

[0083] Specifically, as shown in Figure 1 , a first partition 16 is arranged in the inside of the box 1, the first partition 16 divides the inside of the box 1 into a first installation area 101 and a second installation area 102, the ammeter 3 is installed in the first installation area 101, the moisture absorption part 5 and the heat drying part 6 are installed in the second installation area 102, and the air drying part 2 is installed on the first partition 16.

[0084] More specifically, as shown in Figure 1 , the first partition 16 is uniformly provided with a first air hole 161, a second air hole 162 and a third air hole 163, the first fan 21 is installed in the first air hole 161, the second fan 22 is installed in the second air hole 162, and the third fan 23 is installed in the third air hole 163.

[0085] Specifically, the moisture absorption part 5 is installed at the center position above the lower panel 12 of the box 1, the telescopic adjusting device 4 is arranged at the center position below the lower panel 12, the telescopic assembly 7 is uniformly arranged on the side of the moisture absorption part 5, and the telescopic assembly 7 is arranged directly below the button device 64.

[0086] This setting is ingenious, on the one hand, it is convenient for the telescopic adjusting device 4 to monitor the balance of the moisture absorption part 5 to control the extension of the telescopic assembly 7; on the other hand, the telescopic assembly 7 can press the button device 64 to start the heat drying part 6 to dehumidify the inside of the box 1 after being extended and lengthened.

[0087] Specifically, the number of the telescopic assemblies 7 is not limited.

[0088] In the embodiment, as shown in Figure 1 and Figure 2 , the number of the telescopic assemblies 7 is set to four.

[0089] Specifically, as shown in Figure 8 , the telescopic assemblies 7 are set to multiple sections, and the circuits triggering the telescoping of the sections are connected in parallel.

[0090] More specifically, as shown in Figure 9 and Figure 10 , the telescopic adjusting device 4 includes a center ball 41 located at the center of the lower plate 12, a plane 42 supporting the center ball 41, and sliding resistors 43 arranged along the lines connecting the center ball 41 and the telescopic assemblies 7 in corresponding directions; the sliding resistors 43 include sliding parts 431 and stationary parts 432, the sliding parts 431 are sleeved on the outside of the stationary parts 432, and the outer ends of the sliding parts 431 are connected with the center ball 41; the number of the sliding resistors 43 is the same as that of the telescopic assemblies 7, and the sliding resistors 43 are connected in series with the circuits triggering the telescoping of the telescopic assemblies 7. The telescopic adjusting device 4 can quickly and accurately control the size of the current of the telescopic assemblies 7.

[0091] When the moisture absorption part 5 starts to absorb the moisture in the box 1, the moisture absorption part 5 will be unbalanced. When the telescopic adjusting device 4 detects that the moisture absorption part 5 is unbalanced, the telescopic adjusting device 4 controls the center ball 41 to tilt and slide to one side, pushes the sliding part 431 of the sliding resistor 43 on the tilted side to slide to the side of the stationary part 432, so that the resistance becomes smaller; the sliding part 431 of the sliding resistor 43 on the other side slides to the outside of the stationary part 432, so that the resistance becomes larger; thereby the current of the corresponding telescopic assemblies 7 becomes larger and smaller, prompting the telescopic assemblies 7 on the tilted side to elongate and the telescopic assemblies 7 on the other side to shorten.

[0092] In the embodiment, the number of the telescopic assemblies 7 and the sliding resistors 43 is set to four.

[0093] Specifically, a weight sensor (not shown in the figure) is arranged below the polymer water-absorbing resin 54, the weight sensor is used to detect the weight of the polymer water-absorbing resin 54, and the weight sensor is communicatively connected with the control module.

[0094] The weight of the polymer water-absorbing resin 54 increases after absorbing water, and the more water the polymer water-absorbing resin 54 absorbs, the more the weight increases. The water absorption capacity of the polymer water-absorbing resin 54 is constant, and when the water absorption capacity of the polymer water-absorbing resin 54 reaches the maximum, the weight of the polymer water-absorbing resin 54 also reaches the maximum, and the polymer water-absorbing resin 54 no longer absorbs water, and the weight of the polymer water-absorbing resin 54 no longer increases.

[0095] In addition to the box body 1, the box door, the control module, the electric meter 3, the moisture absorption part 5, the heat drying part 6, the telescopic adjustment device 4, and the telescopic assembly 7, the moisture-proof electric meter box also includes other related components. The specific structure and assembly relationship of the related components are prior art and will not be described here.
