[0002] An electrical protection box is a device specially used to protect electrical equipment. It is mainly used to provide a safe and stable working environment for electrical equipment to prevent it from being disturbed and damaged by the external environment such as dust and vibration. At the same time, when electrical equipment fails, such as short circuit, overload, etc., the electrical protection box can quickly cut off the power supply or take other protective measures to prevent sparks, discharges and other dangerous situations, and protect the safety of personnel and equipment. In addition, it can also provide a stable working environment to reduce the failure rate of electrical equipment, thereby extending its service life. Electrical protection boxes are widely used in various places where electrical equipment is required, and are one of the important equipment to ensure the safe and stable operation of the power system.

[0003] In the related art, when an electrical protection box is in use, it is placed at the workplace, and then electrical equipment is placed in the protection box to protect the electrical equipment.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] The following describes an electrical protection box 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0034] like Figure 1-7 As shown, the electrical protection box 100 according to the embodiment of the present invention includes a box body 1 , a first baffle 2 , a second baffle 3 and a ventilation assembly 4 .

[0035] The box 1 has a chamber, an air inlet (not shown in the figure) and an air outlet 12. The air inlet is arranged at the top of the box 1, and the air outlet 12 is arranged at the bottom of the box 1. The air inlet and the air outlet 12 are both connected to the chamber. The chamber is suitable for storing electrical equipment. Specifically, Figure 1-2 As shown, the box body 1 is a rectangular box extending in the up-down direction, the air inlet is arranged at the top of the box body 1, the air outlet 12 is arranged at the bottom of the box body 1, and the air inlet and the air outlet 12 are arranged opposite to each other in the up-down direction, so that the air flow can flow into the chamber through the air inlet and flow out of the chamber from the air outlet 12, thereby ventilating the box body 1 and ensuring the dryness of the electrical equipment in the box body 1.

[0036] The first baffle 2 and the second baffle 3 are both arranged in the chamber, the first baffle 2 is arranged at the top of the box body 1, and the second baffle 3 is arranged at the bottom of the box body 1, and the first baffle 2 and the second baffle 3 both have a first position and a second position in the box body 1. In the first position, the first baffle 2 is arranged below the air inlet so that the first baffle 2 blocks the air inlet, and the second baffle 3 is arranged above the air outlet 12 so that the second baffle 3 blocks the air outlet 12. In the second position, the first baffle 2 and the air inlet are spaced apart along the length direction of the box body 1, and the second baffle 3 and the air outlet 12 are spaced apart along the length direction of the box body 1 so that the air inlet and the air outlet 12 are open. Specifically, as Figure 1-2 As shown, the first baffle 2 and the second baffle 3 are both horizontal plates extending in the left-right direction and are both arranged in the chamber. The first baffle 2 is arranged at the top of the box body 1, and the second baffle 3 is arranged at the bottom of the box body 1. The first baffle 2 and the second baffle 3 can both move between a first position and a second position along the left-right direction. In the first position, the first baffle 2 covers the air inlet and the second baffle 3 covers the air outlet 12, thereby preventing airflow from flowing into the chamber. In the second position, the first baffle 2 is located on the right side of the air inlet and the second baffle 3 is located on the right side of the air outlet 12. As a result, the air inlet and the air outlet 12 are opened, so that the box body 1 is ventilated to dehumidify the box body 1.

[0037] The ventilation assembly 4 is arranged at the top of the box body 1 and is located outside the chamber. The ventilation assembly 4 is connected to the air inlet so that the ventilation assembly 4 can deliver air through the air inlet. Figure 1 As shown, the ventilation component 4 is arranged on the top of the box body 1 and is connected to the air inlet. When the first baffle 2 and the second baffle 3 are in the second position, the ventilation component 4 is opened, so that the ventilation component 4 ventilates the chamber through the air inlet and flows out from the air outlet 12, thereby dehumidifying the box body 1.

[0038] The electrical protection box 100 of the embodiment of the present invention is provided with a first baffle 2 and a second baffle 3, so that the air inlet and the air outlet 12 can be blocked by the first baffle 2 and the second baffle 3, so as to prevent moisture from entering the chamber when the external humidity is heavy in rainy weather, so as to prevent moisture from affecting the electrical equipment, achieve better moisture-proof effect, and help to extend the service life of the electrical protection box 100. A ventilation component 4 is provided, so that when the air inlet and the air outlet 12 are in an open state, the ventilation component 4 can bring the outside air into the protection box through the air inlet and accelerate the flow of the air inside it, so as to help to quickly disperse the moisture in the protection box through the air outlet 12, further improve the moisture-proof effect, and extend the service life of the electrical protection box 100.

[0039] In some embodiments, the electrical protection box 100 further includes a plurality of mounting plates 5, which are arranged in the box body 1 at intervals along the vertical direction, so that the mounting plates 5 divide the box body 1 into a plurality of sub-cavities, each of which is used to store electrical equipment, and a plurality of ventilation holes on the mounting plates 5 that penetrate the mounting plates 5 in the vertical direction, and the plurality of ventilation holes are arranged in a plurality of rows along the length direction of the mounting plates 5, and each row includes a plurality of ventilation holes arranged at intervals along the width direction of the mounting plates 5. Specifically, as Figure 1-2 As shown, the mounting plate 5 is arranged in the chamber at intervals along the up-down direction to divide the chamber into a plurality of sub-cavities, each of which can store electrical equipment, thereby rationally utilizing the space of the chamber, and the mounting plate 5 is provided with a plurality of ventilation holes penetrating the mounting plate 5 along the up-down direction, and the ventilation holes are arranged in a plurality of rows at intervals along the left-right direction, and each row includes a plurality of ventilation holes arranged at intervals along the front-back direction, thereby allowing airflow to flow into the lower sub-cavity through the ventilation holes, thereby ensuring the circulation of airflow.

[0040] In some embodiments, the ventilation assembly 4 includes a housing 41 , a water absorbing member 42 and an impeller 43 .

[0041] The housing 41 is disposed above the air inlet and communicated with the air inlet. An opening is disposed on one side of the housing 41 so that air can flow into the housing 41 through the opening. Figure 1-2 As shown, the shell 41 is a rectangular shell without a bottom surface. The shell 41 is arranged on the box body 1 and covers the air inlet. The shell 41 is connected to the air inlet. An opening is provided on the right side of the shell 41, so that the air flow can flow into the shell 41 through the opening and then flow into the chamber through the air inlet.

[0042] In some embodiments, the water absorbing member 42 is disposed in the housing 41 and above the air inlet, and the water absorbing member 42 is used to absorb moisture from the air flowing into the box body 1. Figure 2-3 As shown, the water absorbing member 42 is disposed in the housing 41 and covers the air inlet. The water absorbing member 42 absorbs moisture from the airflow flowing into the box body 1 to dehumidify the airflow and ensure the dryness of the airflow.

[0043] The impeller 43 is rotatably disposed in the housing 41 and adjacent to the opening of the housing 41. The impeller 43 draws air into the housing 41. Specifically, Figure 2 and 6 As shown, there are two impellers 43, both of which are rotatably disposed in the shell 41 and located at the opening of the shell 41. The motor is disposed on the shell 41 and connected to the impeller 43, so that the impeller 43 is driven to rotate by the motor, so that the air flow is drawn into the chamber through the impeller 43.

[0044] In some embodiments, the water absorbing member 42 includes a first mesh plate 421 , a second mesh plate 422 and a water absorbing layer 423 .

[0045] The first mesh plate 421 and the second mesh plate 422 are detachably connected and the first mesh plate 421 and the second mesh plate 422 are spaced apart in the up-down direction to form an installation cavity. Figure 6-7 As shown, the first mesh plate 421 and the second mesh plate 422 are both mesh plates extending horizontally, and the first mesh plate 421 and the second mesh plate 422 are arranged at intervals in the up-down direction to form a mounting cavity.

[0046] The water absorbing layer 423 is arranged in the installation cavity to absorb the moisture flowing into the air. Figure 6-7 As shown, the water absorption layer 423 is a horizontal water absorption layer 423 extending in the left-right direction. The water absorption layer 423 can be a high-efficiency moisture absorption material such as molecular sieve, activated carbon, etc. The water absorption layer 423 is arranged between the first mesh plate 421 and the second mesh plate 422, so that the airflow is dehumidified through the water absorption layer 423.

[0047] In some embodiments, the electrical protection box 100 further includes a filter 6, which is disposed at the opening of the housing 41 and is used to filter impurities in the air flowing into the housing 1. Specifically, Figure 6 As shown, the filter element 6 can be a filter net, which can effectively block dust, particles and other impurities in the external air, preventing these impurities from entering the box body 1 and affecting the normal operation of the electrical equipment.

[0048] In some embodiments, Figure 7 As shown, a first magnet 43 is provided on the first mesh plate 421, and a second magnet 44 is provided at the air inlet. The first magnet 43 and the second magnet 44 are attracted to each other so that the first mesh plate 421 is detachably connected to the air inlet. A slide groove is provided on one of the first mesh plate 421 and the second mesh plate 422, and a slide rail is provided on the other of the first mesh plate 421 and the second mesh plate 422, so that the second mesh plate 422 is slidably connected to the first mesh plate 421, thereby, the water absorbent member 42 can be pulled out with the second mesh plate 422, so that the water absorbent member 42 can be replaced.

[0049] In some embodiments, the electrical protection box 100 further includes a driving assembly 7, which is disposed on the box body 1 and connected to the first baffle 2 and the second baffle 3, and is used to drive the first baffle 2 and the second baffle 3 to move between the first position and the second position. Thus, the first baffle 2 and the second baffle 3 are driven to move between the first position and the second position by the driving assembly 7, providing movement power for the first baffle 2 and the second baffle 3.

[0050] In some embodiments, the driving assembly 7 includes a motor (not shown in the figure), a winding wheel 72 , a first connecting rope 73 , a second connecting rope 74 , a first coil spring 75 and a second coil spring 76 .

[0051] The motor is disposed in the box body 1, and the winding wheel 72 is rotatably disposed in the box body 1 and connected to the motor. Figure 2-5 As shown, the motor is arranged in the box body 1, the winding wheel 72 is arranged in the box body 1 and is located in the middle of the box body 1, and the winding wheel 72 is connected to the motor, so that the motor drives the winding wheel 72 to rotate forward or reverse.

[0052] One end of the first connecting rope 73 is wound around the winding wheel 72, and the other end of the first connecting rope 73 is connected to the first baffle 2, so that the first connecting rope 73 drives the first baffle 2 to move. One end of the second connecting rope 74 is wound around the winding wheel 72, and the other end of the second connecting rope 74 is connected to the second baffle 3, so that the second connecting rope 74 drives the second baffle 3 to move. Specifically, Figure 4-5 As shown, the lower end of the first connecting rope 73 is wound around the winding wheel 72, the upper end of the first connecting rope 73 is connected to the right end of the first baffle 2, the upper end of the second connecting rope 74 is wound around the winding wheel 72, and the lower end of the second connecting rope 74 is connected to the right end of the second baffle 3. Therefore, when the motor drives the winding wheel 72 to rotate forward, the first connecting rope 73 and the second connecting rope 74 are wound around the winding wheel 72, and when the motor drives the winding wheel 72 to rotate reversely, the winding wheel 72 releases the first connecting rope 73 and the second connecting rope 74.

[0053] The first coil spring 75 and the second coil spring 76 are both arranged in the box body 1, and the first coil spring 75 is connected to the side of the first baffle 2 away from the first connecting rope 73, and the second coil spring 76 is connected to the side of the second baffle 3 away from the second connecting rope 74.

Therefore, when the first baffle 2 and the second baffle 3 move from the first position to the second position, the motor can be rotated forward so that the first connecting rope 73 and the second connecting rope 74 are wound around the winding wheel 72, thereby driving the first baffle 2 and the second baffle 3 to move to the right, so that the air inlet and the air outlet 12 are opened, and when the first baffle 2 and the second baffle 3 move from the second position to the first position, the motor can be flipped, so that the winding wheel 72 releases the first connecting rope 73 and the second connecting rope 74, and the first coil spring 75 and the second coil spring 76 pull the first baffle 2 and the second baffle 3 to move to the left to block the air inlet and the air outlet 12.

[0054] In some embodiments, the electrical protection box 100 further includes a first sliding bar 77 , a second sliding bar 78 , a third sliding bar 79 and a fourth sliding bar 80 .

[0055] The first slide bar 77 and the second slide bar 78 are both arranged in the box body 1 and extend along the length direction of the box body 1. The first slide bar 77 and the second slide bar 78 are arranged on both sides of the first baffle 2, and the first slide bar 77 and the second slide bar 78 are penetrated on the first baffle 2 so that the first baffle 2 slides on the first slide bar 77 and the second slide bar 78. Specifically, as Figure 4 As shown, the first slide bar 77 and the second slide bar 78 both extend in the left-right direction and are spaced apart in the front-back direction. The left and right ends of the first slide bar 77 and the second slide bar 78 are connected to the top of the box body 1. The first baffle plate 2 is arranged between the first slide bar 77 and the second slide bar 78. Support blocks 81 are provided at the front and back ends of the first baffle plate 2. The support block 81 is provided with a slide groove that penetrates the support block 81 in the left-right direction. The first slide bar 77 and the second slide bar 78 are both inserted in the slide groove, so that the first baffle plate 2 can slide smoothly between the first position and the second position.

[0056] In some embodiments, the third slide bar 79 and the fourth slide bar 80 are both arranged in the box body 1 and the third slide bar 79 and the fourth slide bar 80 extend along the length direction of the box body 1, the third slide bar 79 and the fourth slide bar 80 are arranged on both sides of the second baffle 3, and the third slide bar 79 and the fourth slide bar 80 are passed through the second baffle 3 so that the second baffle 3 slides on the third slide bar 79 and the fourth slide bar 80.

[0057] Specifically, Figure 4 As shown, the third slide bar 79 and the fourth slide bar 80 both extend in the left-right direction and are spaced apart in the front-back direction, the left and right ends of the third slide bar 79 and the fourth slide bar 80 are connected to the bottom of the box body 1, the second baffle plate 3 is arranged between the third slide bar 79 and the fourth slide bar 80, and the front and rear ends of the second baffle plate 3 are both provided with support blocks 81, the support block 81 is provided with a slide groove that penetrates the support block 81 in the left-right direction, the third slide bar 79 and the fourth slide bar 80 are both inserted in the slide groove, so that the second baffle plate 3 can slide smoothly between the first position and the second position.

[0058] In some embodiments, the electrical protection box 100 has a first working state and a second working state. In the first working state, the first baffle 2 and the second baffle 3 are both in the first position, and the ventilation component 4 is closed. In the second working state, the first baffle 2 and the second baffle 3 are both in the second position, and the ventilation component 4 is closed or opened. Specifically, when it is rainy or the humidity outside the box body 1 is high, the electrical protection box 100 is in the first working state, the first baffle 2 and the second baffle 3 are in the first position, so that the air inlet and the air outlet 12 are closed to prevent the external air flow from flowing into the chamber, and the ventilation component 4 is closed. When ventilation and dehumidification are required, the electrical protection box 100 is in the second working state, the first baffle 2 and the second baffle 3 are both in the second position so that the air inlet and the air outlet 12 are opened, and the ventilation component 4 is closed or opened according to the actual situation, thereby ensuring the dehumidification efficiency of the electrical protection box 100.

[0059] Working principle: When using the electrical protection box 100 with a moisture-proof structure, the electrical equipment is placed on the mounting plate 5 in the box body 1. When the humidity sensor detects that the humidity in the box body 1 is high, the ventilation component 4 is operated so that the outside air can be brought into the box body 1 through the air inlet and the flow of the air inside it is accelerated, so that the moisture in the box body 1 can be quickly dispersed through the air outlet 12. At the same time, the incoming air can be dehumidified through the water absorption layer 423, so that the moist air can be prevented from entering and affecting the electrical equipment. When the outside humidity is high in rainy weather, , start the drive motor so that the output end of the drive motor drives the winding wheel 72 to rotate, so that the first connecting rope 73 and the second connecting rope 74 can be unwound through the winding wheel 72, and at the same time, the first coil spring 75 and the second coil spring 76 automatically reset and pull the first baffle 2 and the second baffle 3 to slide horizontally, so that the air inlet and the air outlet 12 can be blocked through the first baffle 2 and the second baffle 3, thereby preventing moisture from entering when the external humidity is heavy in rainy weather, thereby preventing moisture from affecting electrical equipment, thereby achieving better moisture-proof effect.
