For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific situations.

[0047] As Figures 1-3 shown in FIGS. 6, 7, and 14, a substation box sealing device according to an embodiment of the present invention includes: a box body 2, an adjustment component 8, and a box door 3;

[0048] The bottom of the box body 2 is provided with an opening 21 for the substation box 1 to be inserted. A second opening 22 is provided on one side wall of the box body 2. An extension portion 4 is provided on the outer side wall of the box body 2 around the second opening 22, and a first sealing strip 5 is installed on the extension portion 4.

[0049] The adjustment component 8 is installed on the box body 2, and the adjustment component 8 forms a first opening 81 corresponding to the opening 21. The first opening 81 is used for the substation box 1 to be inserted, and the adjustment component 8 can adjust the size of the first opening 81.

[0050] The box door 3 is provided on one side of the box body 2 for opening and closing the second opening 22. When the box door 3 closes the second opening 22, the first sealing strip 5 abuts against the inner side surface of the box door 3.

[0051] It should be noted that the box body 2 of the sealing device is sleeved outside the substation box 1. The substation box 1 enters the box body 2 from the opening 21 at the bottom of the box body 2 and is sleeved inside the first opening 81 formed by the adjusting component 8. The size of the first opening 81 is adjusted so that the adjusting component 8 abuts against the outer side of the substation box 1 to narrow the gap between the substation box 1 and the sealing device. When the box door 3 closes the second opening 22, the first sealing strip 5 installed on the extension part 4 abuts against the inner side surface of the box door 3, improving the sealing effect of the sealing device on the substation box 1. This application can sleeve the sealing device outside the original substation box 1, which is convenient for installation.

[0052] Even if moisture enters the box body 2 of the sealing device, before the moisture enters the interior of the substation box 1, the sealing device can be promptly detached from the substation box 1, which is convenient for removal. Then, the replaced sealing device is sleeved outside the substation box 1, effectively reducing the entry of moisture into the substation box 1, avoiding the migration of the internal components of the box body of the already operating substation box 1, and the situations of reinstallation, wiring, and debugging, reducing the maintenance cost and shortening the construction time and power outage time.

[0053] The extension part 4 is preferably integrally formed with the outer side wall of the box body 2 to avoid the gap at the connection and improve the sealing performance.

[0054] As Figures 5-7 shown, in this embodiment, the adjusting component 8 includes:

[0055] Four first sealing plates 82, the four first sealing plates 82 are connected end to end in sequence and installed on the box body 2, and two opposite first sealing plates 82 can move towards or away from each other. A first opening 81 is defined between the four first sealing plates 82.

[0056] It should be noted that the box body 2 is sleeved outside the substation box 1. The substation box 1 passes through the opening 21 at the bottom of the box body 2 and the first opening 81 between the four first sealing plates 82 in sequence. Two opposite first sealing plates 82 can move towards or away from each other. Therefore, when two opposite first sealing plates 82 move towards each other, the length or width of the first opening 81 can be adjusted to be smaller, and when two opposite first sealing plates 82 move away from each other, the length or width of the first opening 81 can be adjusted to be larger, thereby being able to seal the gap between the box body 2 and the substation box 1 and improving the sealing effect.

[0057] The size of the opening 21 is larger than the outer shape sizes of all substation boxes 1 on the market, and the maximum size of the first opening 81 is larger than the outer shape sizes of all substation boxes 1 on the market, ensuring that the substation box 1 can be sleeved into the opening 21 and the first opening 81.

[0058] To improve the sealing performance, self-leveling sealant can be poured into the gap between the first opening 81 and the substation box 1 for sealing.

[0059] As Figure 7 shown, in this embodiment, further, in a more specific embodiment, the adjusting component 8 further includes a connecting member 83. The first sealing plate 82 is provided with a sliding groove 821 extending along the width or length direction of the first sealing plate 82 at the connection with an adjacent first sealing plate 82. The connecting member 83 passes through the sliding grooves of two adjacent first sealing plates 82 and connects the two adjacent first sealing plates 82.

[0060] It should be noted that the first sealing plate 82 is provided with a sliding groove 821 extending along the width direction of the first sealing plate 82 at the connection with an adjacent first sealing plate 82, so that the first sealing plate 82 can move back and forth along its width direction (alternatively, a sliding groove 821 extending along the length direction of the first sealing plate 82 is provided, so that the first sealing plate 82 can move back and forth along its length direction), and the size of the first opening 81 formed between the four sealing plates 82 can be adjusted. By passing the connecting member 83 through the sliding grooves of two adjacent first sealing plates 82 and connecting the two adjacent first sealing plates 82, the relative positions of the two adjacent first sealing plates 82 are fixed.

[0061] The connecting member 83 is preferably a bolt.

[0062] As Figures 2-3 shown in FIGS. 14 and 15, in this embodiment, it further includes: a base 7;

[0063] The base 7 is installed at the bottom of the box body 2. The base 7 is provided with an opening channel 73 that penetrates from the bottom to the top. The opening channel 73 communicates with the opening 21. The base 7 is installed with a footrest 9 for adjusting the height.

[0064] It should be noted that the size of the opening channel 73 is larger than the outer dimensions of all substation boxes 1 on the market, ensuring that the substation box 1 can pass through the opening channel 73, the opening 21, and the first opening 81 in sequence.

[0065] Since the height of the base 7 of the sealing device needs to be higher than the height of the base of the substation box 1 in on-site operation to ensure the sealing reliability between the sealing device and the substation box 1, the base 7 is installed with a footrest 9 for adjusting the height to adapt to the bases of substation boxes 1 with different heights.

[0066] As Figure 3 、 8 shown, in this embodiment, further, a cavity 71 is provided inside the base 7, and an installation hole 72 is provided at the bottom of the base 7. The installation hole 72 penetrates to the cavity 71;

[0067] The pedestal 9 includes a fixed base 91, a seat body 92, an adjusting bolt 93 and an adjusting nut 94. The fixed base 91 is installed in the mounting hole 72. One end of the adjusting bolt 93 is vertically connected to the seat body 92. The other end of the adjusting bolt 93 passes through the fixed base 91 and enters the cavity 71. The adjusting nut 94 is sleeved on the adjusting bolt 93 and fixed at the top of the fixed base 91.

[0068] It should be noted that the fixed base 91 of the pedestal 9 is installed in the mounting hole 72 at the bottom of the base 7. One end of the adjusting bolt 93 is vertically connected to the seat body 92. The other end of the adjusting bolt 93 passes through the fixed base 91 and enters the cavity 71. The adjusting nut 94 is sleeved on the adjusting bolt 93 and fixed at the top of the fixed base 91. The seat body 92 is placed on the ground. By rotating the relative position between the adjusting bolt 93 and the adjusting nut 94, the height of the base 7 can be adjusted, and then the height of the box body 2 can be adjusted, so that the height of the base 7 of the sealing device is higher than the height of the base of the substation box 1 in on-site operation, ensuring the sealing reliability between the sealing device and the substation box 1.

[0069] As Figure 14 shown, in this embodiment, a second sealing strip 6 is installed on the inner side of the box door 3. When the box door 3 closes the second opening 22, the second sealing strip 6 surrounds the first sealing strip 5 and abuts against the outer side wall of the box body 2.

[0070] It should be noted that when the box door 3 closes the second opening 22, the first sealing strip 5 abuts against the inner side of the box door 3, the second sealing strip 6 surrounds the first sealing strip 5 and abuts against the outer side wall of the box body 2. The two-layer sealing of the first sealing strip 5 and the second sealing strip 6 can improve the sealing performance of the box body 2 of the sealing device, thus providing a better sealing effect for the substation box 1 inside the box body 2 and being more conducive to preventing moisture from entering the substation box 1.

[0071] As Figures 9-14 shown, in this embodiment, further, the box door 3 includes:

[0072] a door panel 31;

[0073] a lining board 32, the lining board 32 is installed on the inner side of the door panel 31. The lining board 32 includes a straight board 321 and a U-shaped board 322 connected to the edge of the straight board 321. The straight board 321 is parallel to and spaced from the door panel 31.

[0074] The U-shaped plate 322 includes a straight section 3221, a first folded section 3222, and a second folded section 3223. The straight section 3221 is parallel to the straight plate 321. The straight section 3221 is fitted to the inner side surface of the door panel 31. The first folded section 3222 and the second folded section 3223 are perpendicularly connected to both ends of the straight section 3221. The first folded section 3222 is connected to the straight plate 321, and the second folded section 3223 is installed with the second sealing strip 6. When the box door 3 closes the second opening 22, the first sealing strip 5 abuts against the inner side surface of the straight section 3221, and the second sealing strip 6 abuts against the outer side wall of the box body 2.

[0075] The reinforcing rib plate 33 is installed between the door panel 31 and the straight plate 321 of the lining plate 32.

[0076] It should be noted that the lining plate 32 is installed on the inner side surface of the door panel 31. The lining plate 32 includes a straight plate 321 and a U-shaped plate 322 connected to the edge of the straight plate 321, which can strengthen the strength of the box door 3 and has fewer parts. The straight section 3221 of the U-shaped plate 322 is fitted to the inner side surface of the door panel 31, the first folded section 3222 is connected to the straight plate 321, and the second folded section 3223 is installed with the second sealing strip 6. When the box door 3 closes the second opening 22, the first sealing strip 5 abuts against the inner side surface of the straight section 3221, and the second sealing strip 6 abuts against the outer side wall of the box body 2, improving the structural stability and enabling a tighter seal.

[0077] Installing the reinforcing rib plate 33 between the door panel 31 and the straight plate 321 of the lining plate 32 can reduce the deformation amount generated during the pressing process of the box door 3 and avoid affecting the sealing effect. The reinforcing rib plate 33 is provided with a lock hole.

[0078] As Figure 14 shown, in this embodiment, the box door 3 and the box body 2 are hinged by a hinge 10.

[0079] It should be noted that the box door 3 and the box body 2 are hinged by a hinge 10, which is convenient for opening the box door 3 and can more accurately locate the abutting positions of the first sealing strip 5 and the second sealing strip 6.

[0080] As Figure 4 、 15 shown, in a more specific embodiment, a third opening 23 is formed in a side wall of the box body 2 away from the box door 3, and the third opening 23 is covered with a second sealing plate 11 detachably connected to the box body 2.

[0081] It should be noted that a third opening 23 is provided on a side wall of the box body 2 away from the box door 3, and a second sealing plate 11 detachably connected to the box body 2 is covered on the third opening 23. Thus, the second sealing plate 11 can be detached from the third opening 23 and extended into the interior of the box body 2 for operation. When sealing is required, the second sealing plate 11 is reinstalled into the third opening 23. To improve the sealing performance, self-leveling sealant can be poured into the gap between the third opening 23 and the second sealing plate 11 for sealing.

[0082] As Figure 15 shown, in a more specific embodiment, the box body 2 is integrally bent from a plate 25, and reinforcing frames 26 are installed along each edge on the inner side surface of the box body 2.

[0083] It should be noted that the box body 2 is integrally bent from a plate 25, reducing the weld seams of the box body 2 and decreasing the possibility of protection failure caused by welding defects. Reinforcing frames 26 are installed along each edge on the inner side surface of the box body 2, which can improve the strength of the box body 2.

[0084] The plate 25 is preferably a high-strength plate such as a steel plate.

[0085] As Figure 1 shown, in a more specific embodiment, a top cover 12 is installed on the top of the box body 2, and a plurality of lifting rings 13 are provided on the top of the top cover 12. The lifting rings 13 are respectively arranged near the four corners of the top cover 12, and the lifting rings 13 can be lifted by a lifting rope, thereby realizing the disassembly and assembly of the sealing device.

[0086] As Figure 1 shown, in a more specific embodiment, a door lock 14 is provided on the box door 3.

[0087] As Figures 2-3 shown, in a more specific embodiment, a dehumidification system 15 is installed in the box body 2, which can create an environment with controllable humidity in the box body 2. A dehumidification system can also be installed in the substation box 1 to assist in dehumidification.

[0088] The working process of the present invention is as follows: The box body 2 of the sealing device is sleeved outside the substation box 1, and the substation box 1 enters the box body 2 from the opening 21 at the bottom of the box body 2 and is sleeved inside the first opening 81 formed by the adjusting component 8. The size of the first opening 81 is adjusted so that the adjusting component 8 abuts against the outer side of the substation box 1 to narrow the gap between the substation box 1 and the sealing device. When the box door 3 closes the second opening 22, the first sealing strip 5 installed on the extension part 4 abuts against the inner side surface of the box door 3, improving the sealing effect of the sealing device on the substation box 1. This application can sleeve the sealing device outside the original substation box 1, which is convenient for installation.

[0089] Even if moisture enters the box body 2 of the sealing device, before the moisture enters the interior of the substation box 1, the sealing device can be promptly detached from the substation box 1, which is convenient for removal. Then, the replaced sealing device is sleeved outside the substation box 1, effectively reducing the entry of moisture into the substation box 1, avoiding the migration of the internal components of the box body of the already operating substation box 1, and the situations of reinstallation, wiring, and debugging, reducing the maintenance cost and shortening the construction time and power outage time.

[0090] In summary, the embodiment of the present invention provides a sealing device for a substation box, which can effectively reduce the entry of moisture into the substation box, avoid the migration of the internal components of the box body of the already operating substation box, and the situations of reinstallation, wiring, and debugging, reducing the maintenance cost and shortening the construction time and power outage time.

[0091] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
