[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] The present utility model provides a skid-mounted substation protection device as shown in Figure 1 and Figure 2 , which includes: a base 1, an outer shell 2 is installed on the top of the base 1, an insulating rubber layer 4 is installed at the bottom end of the outer shell 2, the insulating rubber layer 4 is in contact with the base 1, two support rods are fixed on the top of the outer shell 2, and a rain guide plate 6 is jointly connected to the tops of the two support rods. A receiving seat 7 is installed inside the outer shell 2.

[0029] As can be seen from the above, during use, first place the base 1 at the place where it needs to be used, then place the equipment of the skid-mounted substation on the receiving seat 7, and protect it through the outer shell 2. Subsequently, support the rain guide plate 6 through the two support rods, so that during rainy weather, the rain guide plate 6 can shield the outer shell 2 from rain, ensuring that the equipment is not invaded by rain, and having a good protection effect on the equipment.

[0030] Referring to Figures 1 - 4 , a disassembly mechanism 3 is located between the outer shell 2 and the insulating rubber layer 4, and the disassembly mechanism 3 includes a fixing plate 31 fixed on one side of the insulating rubber layer 4 and a slot opened on the top of the fixing plate 31. A positioning plate 33 is inserted into the slot. A control plate 32 is fixed on one side of the positioning plate 33. An anti-offset mechanism for preventing the positioning plate 33 from shifting is arranged between the control plate 32 and the fixing plate 31. A limiting mechanism for limiting the positioning plate 33 is arranged between the positioning plate 33 and the outer shell 2. The anti-offset mechanism includes two positioning grooves penetrating through the inside of the fixing plate 31 and positioning rods 36 inserted into the two positioning grooves. One side of the two positioning rods 36 is fixed to the control plate 32. The limiting mechanism includes a limiting groove opened on one side of the outer shell 2 and a receiving groove opened on the top of the limiting groove. The positioning plate 33 corresponds to the limiting groove. An insertion mechanism for inserting the positioning plate 33 is arranged between the receiving groove and the positioning plate 33. The insertion mechanism includes an opening groove opened on one side of the positioning plate 33 and a limiting block 34 installed inside the receiving groove. The limiting block 34 corresponds to the opening groove, and a spring 35 is connected between the limiting block 34 and the receiving groove.

[0031] Through the above technical solution:

[0032] During use, first pull the limit block 34 to make it move in the storage groove. The movement of the limit block 34 drives the spring 35 to contract, so that the limit block 34 is separated from the opening groove. After the separation of the limit block 34 from the opening groove, pull the control plate 32 to drive the positioning plate 33 to move. The movement of the control plate 32 drives the positioning rod 36 to move in the fixed plate 31, so that the positioning plate 33 is separated from the limit groove. After the separation of the positioning plate 33 from the limit groove, the control and adjustment mechanism 5 is used to drive the moving housing 2 to drive the insulating rubber layer 4 to move, so that the insulating rubber layer 4 is separated from the base 1. After the separation of the insulating rubber layer 4 from the base 1, the rapid disassembly of the insulating rubber layer 4 can be realized, which is convenient for the replacement of the insulating rubber layer 4, solves the problem that maintenance personnel of the existing device may need to spend more time and energy when replacement or repair is needed, increases the difficulty of maintenance, avoids the situation of the decline of the insulation performance of the insulating rubber layer 4, reduces the safety risks such as electric leakage of the device, and further makes the operation efficiency of the entire substation higher, increasing the reliability and safety of the substation.

[0033] In addition, as shown in Figures 1 - 5 Figure 5, an adjustment mechanism 5 for adjusting the height of the housing 2 is provided between the base 1 and the housing 2. The adjustment mechanism 5 is provided on both sides of the housing 2. The adjustment mechanism 5 includes a fixed seat 52 fixed on the top of the base 1 and a moving plate 51 installed on one side of the housing 2. A threaded rod 53 is connected between the moving plate 51 and the fixed seat 52. The threaded rod 53 is screwed with the moving plate 51, and the threaded rod 53 extends to the top of the moving plate 51 and is fixed with a rotating disk 55. A control rod is installed on the top of the rotating disk 55. A positioning mechanism for positioning the moving plate 51 is provided between the moving plate 51 and the base 1. The positioning mechanism includes two movable columns 54 fixed on the top of the base 1 and two slot holes opened inside the moving plate 51. The two movable columns 54 correspond to the two slot holes.

[0034] Through the above technical solutions:

[0035] When it is not rainy weather, rotating the control rod drives the rotating disk 55 to rotate. The rotation of the rotating disk 55 drives the threaded rod 53 to start rotating. Through the rotation of the threaded rod 53, the moving plate 51 moves on its outer wall. The movement of the moving plate 51 drives the synchronous movement of the outer shell 2. Thus, the outer shell 2 drives the insulating rubber layer 4 to move. After separating the insulating rubber layer 4 from the base 1, the rotation of the control rod can be stopped. By separating the insulating rubber layer 4 from the base 1, the height of the outer shell 2 can be adjusted, thereby avoiding the situation that the insulating rubber layer 4 abuts against the base 1 for a long time in non-rainy weather. At the same time, it can avoid the long-term friction of the insulating rubber layer 4, reduce the maintenance cost and downtime, improve the operation efficiency of the device, reduce the damage and aging of the insulating rubber layer 4, effectively increase the service life of the insulating rubber layer 4, and reduce the replacement and maintenance frequency.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
