[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-8 As shown in the embodiment of the present invention, a fireproof and moisture-proof power cabinet includes an outer cabinet 1 and an inner cabinet 7. The inner wall of the outer cabinet 1 is coated with a moisture-proof layer 4, which blocks external moisture. A hydraulic cylinder 10 is bolted to the bottom inner wall of the moisture-proof layer 4. The output shaft of the hydraulic cylinder 10 lifts the inner cabinet 7 upward. A cabinet door 31 is movably connected to one side of the outer cabinet 1 via a hinge. A cabinet door 31 is provided on the front of the inner cabinet 7. A cabinet box 2 is bolted to the top of the outer cabinet 1. A dry powder cover 23 is movably installed at the lower end of the cabinet box 2. A dry powder box 20 is bolted to the inside of the cabinet box 2. The dry powder box 20 contains dry powder for fireproofing.

[0030] In another embodiment provided by the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, protruding posts 32 are fixedly installed on both sides of the inner cabinet 7, and a latching rod 14 is movably attached to the outside of the protruding post 32. An anti-slip pad 27 is provided on one side of the outer wall of the latching rod 14. Gears 15 are provided on both sides of the inner cabinet 7. One side of the latching rod 14 is fixedly installed on the outer wall of the gear 15. After the hydraulic cylinder 10 pushes the inner cabinet 7, the inner cabinet 7 is raised and lowered on the side of the vertical rod 5. During the raising and lowering, the inner cabinet 7 and the vertical rod 5 slide relative to each other. The gear 15 is driven to rotate through the toothed groove 34 on the side of the vertical rod 5, thereby driving the gear 15 on the side of the inner cabinet 7, thereby causing the latching rod 14 to rotate and lock onto the outside of the latching block 13, so that the cabinet door 31 is tightly attached to the outer wall of the inner cabinet 7, preventing the entry of external moisture.

[0031] In another embodiment provided by the present invention, such as Figure 3 , Figure 4 and Figure 5 As shown, grooves 12 are provided on both sides of the inner wall of the cabinet door 31. A buckle block 13 is fixedly installed on the inner wall of the groove 12. A strip-shaped movable groove 33 is provided on one side of the buckle rod 14. The strip-shaped movable groove 33 of the buckle rod 14 moves outside the protrusion 32, so that the buckle rod 14 is locked and surrounded by the buckle block 13, so that the cabinet door 31 is tightly attached to the outer wall of the inner cabinet 7, preventing the entry of external moisture.

[0032] In another embodiment provided by the present invention, such as Figure 2 and Figure 6As shown, limit frames 25 are welded to both sides of the inside of the cabinet 2, and limit strips 26 are movably inserted into the inside of the limit frames 25. The limit strips 26 move in the limit frames 25. A dry powder cover 23 is movably installed at the lower end of the cabinet 2. An electric telescopic rod 11 is installed on the inner wall of the top of the cabinet 2 by bolts. Several spray heads 24 are installed on the bottom of the dry powder cover 23 by bolts. The output end of the electric telescopic rod 11 pushes the dry powder cover 23 downward.

[0033] In another embodiment provided by the present invention, such as Figure 2 and Figure 6 As shown, an air pump 21 is bolted to the inner wall of the bottom of the dry powder box 20. A powder conveying pipe 22 is provided on one side of the top of the dry powder box 20. A fireproof opening 17 is provided on the top of the inner cabinet 7. The dry powder cover 23 is pushed down to the fireproof opening 17. One end of the powder conveying pipe 22 is fixedly inserted into the top of the dry powder cover 23. The spray head 24 sprays out the dry powder in the dry powder cover 23. The connecting pipe of the air pump 21 is connected to the dry powder in the dry powder box 20. After the air pump 21 is started, the dry powder is sprayed out from the dry powder box 20.

[0034] In another embodiment provided by the present invention, such as Figure 2 and Figure 8 As shown, several moisture-proof pads 19 are adhered to the inner wall of the inner cabinet 7. The moisture-proof pads 19 reduce the intrusion of moisture. A fireproof board 8 is fixedly installed on the inner wall of the moisture-proof pads 19. Fire-retardant filler 18 is filled between the fireproof board 8 and the inner wall of the inner cabinet 7. The fireproof board 8 and the fire-retardant filler 18 block the external fire.

[0035] In another embodiment provided by the present invention, such as Figure 2 and Figure 8 As shown, the inner wall of the fireproof board 8 is provided with a fire-resistant layer 16, which blocks external fire. The bottom outer wall of the outer cabinet 1 is welded with a base 3 on both sides.

[0036] In another embodiment provided by the present invention, such as Figure 1 and Figure 7 As shown, a heat dissipation frame 30 is fixedly installed on one side of the outer cabinet 1, and a heat dissipation mesh 29 is installed on the inner wall of the heat dissipation frame 30 by bolts. A heat dissipation cover 28 is threadedly connected to the outer wall of the heat dissipation frame 30. After the heat dissipation cover 28 is rotated and opened, the heat in the outer cabinet 1 can be dissipated through the heat dissipation mesh 29.

[0037] In another embodiment provided by the present invention, such as Figure 2 and Figure 6 As shown, the bottom outer wall of the inner cabinet 7 is fixedly installed on the top of the hydraulic cylinder 10, and the bottom end of the electric telescopic rod 11 is installed on the top of the dry powder cover 23 by bolts. The electric telescopic rod 11 can push the dry powder cover 23 to move downward.

[0038] In another embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, fans 9 are bolted to both sides of the inner side of the outer cabinet 1. The fans 9 exhaust the heat from the outer cabinet 1. Sleeves 6 are welded to both sides of the inner cabinet 7. Vertical rods 5 are welded to both sides of the bottom inner wall of the moisture-proof layer 4. The outer wall of the vertical rods 5 is provided with toothed grooves 34. The sleeves 6 are slidably installed on the outside of the vertical rods 5. The sleeves 6 move outside the vertical rods 5, so that the movement of the inner cabinet 7 is limited.

[0039] For example, especially important, please see Figure 4 In one embodiment, the inner cabinet 7 is provided with two limiting posts 105, which are located on the upper and lower sides of the latching rod 14, respectively. The two limiting posts 105 limit the rotation angle of the latching rod 14 to prevent it from flipping arbitrarily or over-flipping. The two limiting posts 105 are located on the upper left and lower left of the protrusion 32, respectively, thus allowing for a larger vertical rotation angle on the right side of the latching rod 14. Each limiting post 105 is provided with a compression spring 101, one end of which is connected to the limiting post 105, and the other end is connected to the center of the end face of the gear 15. The included angle between the two compression springs 101 is 30-75 degrees. For example, the angle between the upper compression spring 101 and the horizontal plane is greater than the angle between the lower compression spring 101 and the horizontal plane. The compression spring 101 is used to drive the gear 15 to mesh tightly with the tooth groove 34. Moreover, the relative arrangement of the two limiting posts 105 and the protrusion 32 prevents the compression spring 101 from flipping, even if the gear 15 moves to the uppermost or lowermost limit position.

[0040] Furthermore, the cooperation of the two compression springs 101 ensures that the combined force between them remains within a reasonable range, making it easier for the gear 15 to return to its original position, i.e., to return to the position where the latching rod 14 is approximately horizontal. This is because, for example, when the gear 15 moves upward to its limit position, the pressure of the lower compression spring 101 gradually decreases to a smaller extent, while the pressure of the upper compression spring 101 increases to a larger extent. The combined force of the two allows the gear 15 to maintain a tight engagement with the tooth groove 34 to the right, but also generates a downward component force, causing the gear 15 to tend to move downward, thereby maintaining a tight engagement with the lower side wall of the tooth groove 34. The limiting post 105 can both perform the limiting function and install the compression spring 101, so that the compression spring 101 pushes the gear 15, and the compression spring 101 can also generate a tendency for the gear 15 to move, so that the gear 15 tightly abuts against the upper or lower side wall of the tooth groove 34. Furthermore, by making the inclination angles of the two compression springs 101 different, the angle between the upper compression spring 101 and the horizontal plane is greater than the angle between the lower compression spring 101 and the horizontal plane. This results in the lower compression spring 101 exerting a greater downward force on the gear 15 than the lower compression spring 101 exerting an upward force on the gear when the latching rod 14 is in the horizontal position. Consequently, the resultant force of the two compression springs 101 on the gear 15 will have a downward component, thus enabling the latching rod 14 to remain engaged with the latching block 13.

[0041] Working principle: Moisture easily accumulates at the bottom of the outer cabinet 1. When the hydraulic cylinder 10 in the outer cabinet 1 is activated, the end of the hydraulic cylinder 10 pushes the inner cabinet 7, which can then be pushed upward and placed against the bottom of the dry powder cover 23. The sleeve 6 slides outside the vertical rod 5, keeping the inner cabinet 7 away from ground moisture. When the cabinet door 31 is opened, the hydraulic cylinder 10 pushes the inner cabinet 7 downward. If the cabinet door 31 is closed at this time, the hydraulic cylinder 10 is activated, pushing the inner cabinet 7 upward. The inner cabinet 7 and the gear 15 slide relative to each other, and the tooth groove 34 on the vertical rod 5 pushes the gear 15 to rotate, causing the latching rod 14 to rotate and engage with the latching block 13, locking the cabinet door 31. The latching rod 14 can then tightly engage the latching block 13, and then... The anti-slip pad 27 on the buckle 14 can be locked onto the outside of the buckle block 13, so that the cabinet door 31 is sealed on one side of the inner cabinet 7. At this time, the inner cabinet 7 is a relatively sealed environment, and external moisture cannot enter the inner cabinet 7. After the personnel start the air pump 21, the dry powder in the dry powder box 20 can be introduced into the dry powder hood 23 through the powder conveying pipe 22. The end of the electric telescopic rod 11 pushes the dry powder hood 23 downward, and the spray head 24 sprays dry powder to extinguish the fire. It can reach the depth of the inner cabinet 7 to prevent the fire from spreading. The fire-resistant filler 18 and the moisture-proof pad 19 are installed between the inner cabinet 7 and the fireproof board 8, which can prevent fire and moisture. The fire-resistant layer 16 blocks the fire. After the fan 9 is started, the heat dissipation cover 28 is rotated, and the heat in the outer cabinet 1 can be discharged through the heat dissipation net 29.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
