Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, and more specifically, to a moisture-proof high-voltage power distribution cabinet. Background Art

[0002] The distribution cabinet is an important device in the power system, the final equipment of the distribution system, and a general term for the motor control center.

[0003] In order to perform moisture-proof treatment on the inside of the distribution cabinet, the prior art: CN220066447U, discloses a moisture-proof structure for the distribution cabinet. The prior art sends hot air into the distribution cabinet, thereby performing emergency moisture-proof treatment on the inside of the distribution cabinet, and can squeeze out the moisture in the absorbent cotton to facilitate subsequent normal use.

[0004] However, the inventors discovered that the structure of the prior art design has some unreasonable aspects: in the prior art, the top frame and ventilation holes on the power distribution cabinet are exposed, so that under normal use, external moisture can enter the cabinet through the top frame and ventilation holes respectively, which increases the amount of moisture entering the cabinet. Although absorbent cotton is provided in the cabinet, the absorption amount of the absorbent cotton is fixed. Excessive moisture will increase the absorption burden of the absorbent cotton, reduce the normal use time of the absorbent cotton, and cause some moisture to be unable to be absorbed completely. Therefore, the heating structure needs to be turned on, which increases resource waste. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a moisture-proof high-voltage distribution cabinet which can close the installation frame when there is less moisture inside the distribution cabinet, thereby minimizing the problem that external moisture enters the cabinet through the installation frame, which increases the burden on the absorbent cotton and causes some moisture to not be absorbed cleanly, further ensuring the moisture-proof effect of the distribution cabinet and increasing the service life of the absorbent cotton.

DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] See also Figure 1 and 4 , the utility model provides the following technical solutions:

[0023] Specifically, it refers to a moisture-proof high-voltage distribution cabinet, including a cabinet body 1. The outer surface of the cabinet body 1 is provided with a heat dissipation hole 19 connected with the interior thereof. At the same time, a dustproof net 20 is fixedly installed in the heat dissipation hole 19, and the dustproof net 20 is flush with the outer surface of the cabinet body 1. Water-absorbing cotton 21 is installed in the heat dissipation hole 19. When in use, external cold air enters the cabinet body 1 through the heat dissipation hole 19 and cools down the components in the cabinet body 1. At the same time, the setting of the water-absorbing cotton 21 can absorb water vapor in the air entering the cabinet body 1, and try to avoid excessive water vapor from entering the cabinet body 1.

[0024] Specifically, an electric push rod 22 is fixedly connected to the inner wall of the heat dissipation hole 19, and the other end of the telescopic rod of the electric push rod 22 is fixedly connected to an extrusion plate 23, which is in contact with the absorbent cotton 21. A drainage groove 24 is opened on the bottom wall of the heat dissipation hole 19 near the absorbent cotton 21, and the lower side of the drainage groove 24 extends out of the outer surface of the cabinet 1. A dustproof net 20 is also fixedly installed in the drainage groove 24.

[0025] When the absorbent cotton 21 is saturated, the electric push rod 22 is started, so that the telescopic rod can push the squeezing plate 23 to squeeze the absorbent cotton 21, so that the water absorbed in the absorbent cotton 21 is squeezed out and finally flows out along the drainage chute 24, thus ensuring the long-term use effect of the absorbent cotton 21.

[0026] Embodiment 2

[0027] See also Figure 1-3 A mounting frame 2 is fixedly installed on the top surface of the cabinet 1, and the mounting frame 2 is connected to the inside of the cabinet 1. A dustproof net 20 is also fixedly installed on the top of the mounting frame 2. A plurality of rotating plates 3 are rotatably connected in the mounting frame 2. When the plurality of rotating plates 3 rotate to a horizontal state, the inside of the mounting frame 2 can be sealed. A control chamber 5 is opened in the side wall of the mounting frame 2. A connecting shaft 4 is fixedly connected to the surface of one side of the rotating plate 3 close to the control chamber 5. The other end of the connecting shaft 4 rotates and penetrates into the control chamber 5 and is rotatably connected to the inner wall of the control chamber 5. A gear 6 is fixedly sleeved on the outer surface of the connecting shaft 4 located in the control chamber 5. A rack 7 is meshed and connected to one side of the gear 6. A connecting plate 8 is fixedly connected to the bottom of the rack 7. A limiting slide bar 9 is fixedly connected to the bottom wall of the control chamber 5. The connecting plate 8 is slidably sleeved on the outer surface of the limiting slide bar 9. A reset spring 10 is fixedly connected between the bottom of the connecting plate 8 and the bottom wall of the control chamber 5. The reset spring 10 is movably sleeved on the outer surface of the limiting slide bar 9. A driving structure is provided in the mounting frame 2.

[0028] When the reset spring 10 is not squeezed, the reset spring 10 will generate a thrust on the connecting plate 8, so that the initial position of the connecting plate 8 is at a higher position in the control chamber 5, and the rack 7 is synchronously at a higher position, so the gear 6 drives the rotating plate 3 to be initially horizontal, and the mounting frame 2 is sealed. Therefore, the above structure can be used to close the mounting frame 2 when there is less moisture inside the distribution cabinet, thereby avoiding external moisture from entering the cabinet 1 through the mounting frame 2, and increasing the burden on the absorbent cotton 21, resulting in the problem that some moisture cannot be absorbed cleanly, further ensuring the moisture-proof effect of the distribution cabinet and increasing the service life of the absorbent cotton 21.

[0029] Specifically, a sealing rubber pad is provided on the outer surface of the rotating plate 3, thereby increasing the sealing between the rotating plates 3 without affecting the rotation of the rotating plate 3, and avoiding the situation where external water vapor enters the cabinet 1 after multiple rotating plates 3 rotate to a horizontal state and seal the mounting frame 2.

[0030] Specifically, the driving structure includes a mounting frame 11, which is fixedly installed in the mounting frame 2. A servo motor 12 is fixedly connected to the bottom of the mounting frame 11. The output shaft of the servo motor 12 rotates and passes through the upper surface of the mounting frame 11. The top of the output shaft of the servo motor 12 is fixedly connected to a fan blade 13. The upper surface of the fan blade 13 is fixedly connected to a first rotating shaft 14. The upper end of the first rotating shaft 14 is fixedly connected to a first bevel gear 15. The upper side of the first bevel gear 15 is meshed and connected to a second bevel gear 17. The side of the second bevel gear 17 is fixedly connected to a second rotating shaft 16. The other end of the second rotating shaft 16 rotates and passes through the control cavity 5. One end of the second rotating shaft 16 located in the control cavity 5 is fixedly connected to a cam 18. The outer surface of the cam 18 contacts the upper surface of the connecting plate 8. A heating wire is provided in the mounting frame 2, and a temperature and humidity sensor is provided in the cabinet 1. The heating wire and the temperature and humidity sensor are both existing technologies and will not be described in detail here.

[0031] When the temperature and humidity sensor detects that the humidity in the cabinet 1 exceeds the standard, the servo motor 12 and the heating wire are started synchronously and drive the fan blade 13 to rotate. At the same time, the first rotating shaft 14 drives the first bevel gear 15 to rotate, and the second bevel gear 17 rotates synchronously under the meshing transmission of the first bevel gear 15, and the second rotating shaft 16 rotates with the second bevel gear 17, so the second rotating shaft 16 drives the cam 18 to rotate, so that the cam 18 can squeeze the connecting plate 8, so that the connecting plate 8 moves downward, and the rack 7 moves downward synchronously, so that the rack 7 drives the gear 6 to rotate ninety degrees, so that the rotating plate 3 no longer blocks the installation frame 2, so that the external air can enter the installation frame 2, and the heating wire can heat and dry the air at the same time, and the heated air enters the cabinet 1, so that the cabinet 1 is filled with dry air, and its internal pressure is greater than the external pressure. Since the servo motor 12 continues to operate, the dry air is finally discharged through the heat dissipation hole 19, and the dry air can dry the squeezed absorbent cotton 21, thereby ensuring the later use effect of the absorbent cotton 21.

[0032] In the present solution, since the output shaft of the servo motor 12 drives the fan blades 13 to rotate at high speed, the cam 18 rotates synchronously at high speed, so that the outer ring of the cam 18 is circular after rotation, which can always form a downward thrust on the connecting plate 8. At the same time, since the servo motor 12 has no self-locking property, when the servo motor 12 stops running, the reset spring 10 loses its extrusion and can push the connecting plate 8 to move to the initial position.

[0033] The utility model provides a moisture-proof high-voltage power distribution cabinet with the following working principle: when the temperature and humidity sensor detects that the humidity in the cabinet 1 exceeds the standard, the servo motor 12 and the heating wire are started synchronously, and the fan blades 13 are driven to rotate, and at the same time, the first rotating shaft 14 drives the first bevel gear 15 to rotate, and the second bevel gear 17 rotates synchronously under the meshing transmission of the first bevel gear 15, and the second rotating shaft 16 rotates with the second bevel gear 17, so the second rotating shaft 16 drives the cam 18 to rotate, so that the cam 18 can squeeze the connecting plate 8, so that the connecting plate 8 moves downward, and the rack 7 moves downward synchronously, so that the rack 7 drives the gear 6 to rotate ninety degrees, so that the rotating plate 3 no longer blocks the installation frame 2, so that the external air can enter the installation frame 2, and at the same time, the heating wire can heat and dry the air, and the heated air enters the cabinet 1, so that the cabinet 1 is filled with dry air, and its internal pressure is greater than the external pressure;

[0034] The electric push rod 22 is started, so that the telescopic rod can push the squeezing plate 23 to squeeze the absorbent cotton 21, so that the water absorbed in the absorbent cotton 21 is squeezed out and finally flows out along the drainage chute 24. Since the servo motor 12 continues to run, the dry air is finally discharged through the heat dissipation holes 19. The dry air can dry the squeezed absorbent cotton 21.
