Description

Technical Field

[0001] The utility model relates to the field of outdoor distribution boxes, in particular to an outdoor distribution box with a dehumidification function. Background Art

[0002] The distribution box is a total circuit distribution box for all users' electricity. The distribution box assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements to form a low-voltage distribution device.

[0003] Most distribution boxes work directly in open air and are easily affected by the external environment. Since there are many electrical components in the distribution box, these electrical components are easily affected by the environment, especially rain and humid environment, which cause great damage to electrical components. Rain and moisture generally enter the distribution box from the vents, and the vents of the distribution box generally cannot perform moisture-proof and dehumidification functions;

[0004] Therefore, it is necessary to propose an outdoor distribution box with a dehumidification function to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an outdoor distribution box with a dehumidification function to solve the problem that rainwater and moisture generally enter the interior of the distribution box through the vents, and the vents of the distribution box generally cannot perform moisture-proof and dehumidification functions.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an outdoor distribution box with a dehumidification function, comprising a box body, an integrated fan for ventilation is arranged inside the box body, a dehumidification shell is fixedly arranged at one end of the box body corresponding to the integrated fan, an outer filter plate, a sponge layer and an inner filter plate are fixedly arranged inside the dehumidification shell in sequence, and filter holes are fixedly opened at one end of the outer filter plate and the inner filter plate;

[0007] A cavity is formed between the sponge layer and the outer filter plate and the inner filter plate;

[0008] A circular plate is fixedly provided at one end of the box body away from the integrated fan, and a plurality of sealing plates are rotatably provided inside the circular plate.

[0009] Preferably, a sealing column is fixedly provided on the upper end of the sealing plate, a rotating shaft is fixedly provided at both ends of the sealing column, and a limiting plate is fixedly provided on the outer side of the rotating shaft.

[0010] Preferably, a plurality of center holes are symmetrically provided on the inner side of the circular plate, a plurality of limiting grooves are symmetrically provided on the inner side of the circular plate, and the limiting grooves are arranged in a fan shape.

[0011] Preferably, the rotating shaft rotates on the inner side of the corresponding center hole, and the limiting plate rotates on the inner side of the corresponding limiting groove.

[0012] Preferably, the limiting groove and the corresponding center hole are connected.

[0013] Preferably, the filter holes on the outer filter plate are larger than the filter holes on the inner filter plate.

[0014] Technical effects and advantages of the utility model:

[0015] 1. The sponge layer intercepts the moisture in the air entering the distribution box, and can also intercept impurities such as dust, achieving two functions. The sponge's own characteristics, which are easy to dry under the sun, prevent more humid air from directly entering the distribution box to achieve a preventive effect. In the event of heavy rain, the formation of the cavity prevents the outer and inner filter plates from directly contacting the sponge layer, causing the liquid to be drained into the distribution box;

[0016] 2. By setting the limit groove, the sealing plate can only let out air. When it is set vertically, it can prevent air from entering the distribution box from the circular plate. When the integrated fan is started, the wind force is used to open the sealing plate to achieve the effect of air circulation, thereby changing the setting of the conventional two-way ventilation holes.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 - Figure 5 An outdoor distribution box with a dehumidification function is shown, comprising a box body 1, an integrated fan 2 for ventilation is arranged inside the box body 1, the integrated fan 2 is driven by an integrated servo motor, and can perform forward and reverse blowing, which is a commonly used prior art and will not be described in detail here. A dehumidification shell 3 is fixedly arranged at one end of the box body 1 corresponding to the integrated fan 2, and an outer filter plate 4, a sponge layer 5 and an inner filter plate 6 are fixedly arranged inside the dehumidification shell 3 in sequence, wherein the sponge layer 5 is arranged in two layers, namely, an acetic sponge and a graphene-based sponge, wherein the graphene-based sponge is arranged close to the inner filter plate 6, and the inner filter plate 6 is arranged close to the integrated fan 2, wherein the acetic sponge is arranged close to the outer filter plate 4, and the acetic sponge is used to absorb moisture in the air by utilizing the good water absorption of the acetic sponge, and the non-water-absorbing property of the graphene-based sponge is utilized to prevent moisture from entering the box body 1 from the integrated fan 2, and filter holes are fixedly opened at one end of the outer filter plate 4 and the inner filter plate 6;

[0025] The filter holes on the outer filter plate 4 are larger than the filter holes on the inner filter plate 6 to complete multi-stage filtration. A cavity 7 is formed between the sponge layer 5 and the outer filter plate 4 and the inner filter plate 6 to prevent the outer and inner filter plates from directly contacting the sponge layer 5, causing the liquid to be drained into the distribution box;

[0026] A circular plate 8 is fixedly provided at one end of the box body 1 away from the integrated fan 2 , and a plurality of sealing plates 10 are rotatably provided inside the circular plate 8 .

[0027] A sealing column 9 is fixedly provided at the upper end of the sealing plate 10 , a rotating shaft 12 is fixedly provided at both ends of the sealing column 9 , and a limiting plate 14 is fixedly provided at the outer side of the rotating shaft 12 .

[0028] A plurality of center holes 11 are symmetrically provided on the inner side of the circular plate 8. The rotating shaft 12 rotates on the inner side of the corresponding center hole 11. A plurality of limiting grooves 13 are symmetrically provided on the inner side of the circular plate 8. The limiting plates 14 rotate on the inner side of the corresponding limiting grooves 13. The limiting grooves 13 are arranged in a fan shape.

[0029] The limiting groove 13 and the corresponding central hole 11 are connected.

[0030] Working principle: the operator turns on the integrated fan 2, so that the integrated fan 2 blows air toward the inside of the distribution box body 1, so that the wind sucked by the integrated fan 2 will first pass through the outer filter plate 4 in the dehumidification shell 3 to filter large particles and other impurities in the air, and then the wind contacts the sponge layer 5, and the acetic sponge in the sponge layer 5 filters the relatively moist air in the air and absorbs moisture to complete the dehumidification, and can perform secondary filtration of dust in the air through the holes on the surface of the acetic sponge, and use the graphene-based sponge to block the water in the acetic sponge, so that the air finally passes through the inner filter plate 6 to enter the inside of the distribution box;

[0031] The integrated fan 2 blows air toward the circular plate 8, thereby blowing up the sealing plate 10, which in turn drives the sealing column 9 to rotate. Then, with the cooperation of the limiting groove 13 and the limiting plate 14, the sealing plate 10 opens a certain angle, allowing air to be discharged, thereby completing the air circulation inside the distribution box;

[0032] When ventilation is not required, the integrated fan 2 stops working, so that the sealing plate 10 naturally sags due to gravity and is arranged vertically, thereby completing the sealing of the circular plate 8 to prevent humid air and impurities from entering the distribution box;

[0033] And the integrated fan 2 blows air toward the dehumidification shell 3 according to its own control program after blowing air toward the inside of the distribution box for a certain period of time, so as to blow away the impurities intercepted on the surface of the sponge layer 5 and the outer filter plate 4, so as to facilitate the long-term use of the sponge layer 5 and the outer filter plate 4 inside the dehumidification shell 3.
