DETAILED DESCRIPTION

[0037] The present application is described in further detail below. Figures 1-6 The present application is described in further detail below.

[0038] The embodiment discloses a prefabricated substation. Referring to Figure 1 and Figure 2 A prefabricated substation comprises a box body 1, wherein a mounting groove 11 is formed in the box body 1, and the mounting groove 11 is used for mounting electrical components. A placement groove 12 is formed in the box body 1, and a plurality of placement springs 121 are fixedly connected to the bottom wall of the placement groove 12 and extend along the length direction of the box body 1.

[0039] Referring to Figure 2 ​A baffle 2 is disposed within the placement slot 12. A placement spring 121 is fixedly connected to the baffle 2 on its surface near the bottom wall of the placement slot 12. The placement spring 121 drives the baffle 2 out of the placement slot 12. When the baffle 2 is fully within the placement slot 12, the placement spring 121 is in a compressed state. When the baffle 2 protrudes from the placement slot 12, the placement spring 121 is in a non-stressed state.

[0040] Reference Figure 3 The baffle 2 has a receiving groove 21 on its surface away from the ground. A first receiving plate 22 and a second receiving plate 23 are rotatably connected within the receiving groove 21. Two torsion springs 211 are fixedly connected within the receiving groove 21. One torsion spring 211 drives the first receiving plate 22 to rotate, while the other torsion spring 211 drives the second receiving plate 23 to rotate. The first receiving plate 22 tilts upwards on the side closest to the torsion spring 211, while the second receiving plate 23 tilts upwards on the side closest to the torsion spring 211. This creates an angle between the first and second receiving plates 22, 23. At this point, the distance between the first and second receiving plates 22, 23 gradually increases in a vertically downward direction, allowing rainwater to fall along the outer surfaces of the first and second receiving plates 22, 23.

[0041] Reference Figure 3 and Figure 4 Guide bars 24 are slidably connected to the sides of the first and second receiving plates 22, 23. Two grooves 241 are defined in the baffle 2, each receiving a different guide bar 24. When the two guide bars 24 are inserted into the respective guide grooves 252, the first and second receiving plates 22, 23 are fixed to the baffle 2. At this point, one side of the first and second receiving plates 22, 23 is tilted, forming an angle between the first and second receiving plates 22, 23.

[0042] Reference Figure 3 and Figure 4 A guide block 25 is slidably connected to the surface of the first and second receiving plates 22 and 23. A limit hole 254 is provided on the surface of the guide block 25, and the limit hole 254 extends in the vertical direction. A guide hole 251 is provided on the surface of the guide block 25 facing the placement slot 12, and the guide hole 251 is connected to the limit hole 254. A guide groove 252 is provided on the surface of the first and second receiving plates 22 and 23, and the guide groove 252 extends along the length of the baffle 2. The guide bar 24 can block the opening of the guide groove 252. Two drop holes 253 are provided on the surface of the baffle 2. When the guide hole 251 is connected to the guide groove 252, the limit hole 254 is connected to the drop hole 253, allowing rainwater to fall through the drop hole 253.

[0043] Reference Figure 3 and Figure 4When the guide strip 24 blocks the opening of the guide groove 252, the guide strip 24 is not located in the groove 241, and at this time, the first containing plate 22 is located in the containing groove 21. When the first containing plate 22 is lifted, the guide strip 24 slides on the first containing plate 22, the guide strip 24 is inserted into the groove 241, so that the guide strip 24 can limit the rotation of the first containing plate 22, then the worker slides the guide block 25 to make the guide hole 251 communicate with the guide groove 252, so that the rainwater can pass through the guide groove 252, the guide hole 251, the limiting hole 254 and the falling hole 253 in turn, and the rainwater can fall down smoothly.

[0044] With reference to Figure 2 and Figure 5 , the limiting plate 3 is provided on the baffle 2, and the moving block 31 is slidingly connected to the surface of the limiting plate 3 close to the ground. The moving groove 26 is formed in the surface of the baffle 2 away from the bottom wall of the placing groove 12, extends in the vertical direction, and is used for sliding of the moving block 31. The activity groove 261 is formed in the surface of the baffle 2 away from the ground, extends in the length direction of the baffle 2, communicates with the moving groove 26, and is used for sliding of the moving block 31.

[0045] With reference to Figure 3 , Figure 4 and Figure 5 , the limiting strip 32 is fixedly connected to the surface of the limiting plate 3, and the limiting strip 32 can be inserted into the limiting hole 254. When the first containing plate 22 and the second containing plate 23 are completely located in the containing groove 21, the two guide blocks 25 can be vertically distributed, and the two guide holes 251 communicate with each other. When the limiting strip 32 is inserted into the limiting hole 254, the first containing plate 22 and the second containing plate 23 can be fixed to each other, and at this time, the first containing plate 22 and the second containing plate 23 are completely located in the containing groove 21.

[0046] With reference to Figure 2 and Figure 4 , the containing groove 13 for insertion of the limiting block is formed in the groove wall of the placing groove 12. When the limiting plate 3 is inserted into the containing groove 13, the limiting strip 32 is still located in the two limiting holes 254, the limiting plate 3 limits the movement of the baffle 2 in the placing groove 12, and the baffle 2 is completely located in the placing groove 12.

[0047] With reference to Figure 3 , Figure 4 and Figure 5When the moving block 31 is located in the moving groove 26, the worker slides the limiting plate 3 upwards, so that the limiting strip 32 is disengaged from the two limiting holes 254, the guiding block 25 can slide on the first containing plate 22 or the second containing plate 23, then the worker rotates the first containing plate 22 and the second containing plate 23, so that the first containing plate 22 and the second containing plate 23 form an included angle, and then the worker slides the limiting plate 3, so that the moving block 31 is moved from the moving groove 26 to the movable groove 261, and the limiting plate 3 abuts against the first containing plate 22 close to the side of the bottom wall of the containing groove 21.

[0048] With reference to Figure 3 and Figure 6 , the surface of the first containing plate 22 close to the bottom wall of the containing groove 21 is slidably connected with a locking strip 27, and the surface of the second containing plate 23 close to the bottom wall of the containing groove 21 is provided with a locking groove 271 for inserting the locking strip 27. When the locking strip 27 is inserted into the locking groove 271, the first containing plate 22 and the second containing plate 23 are fixed to each other, and at this time, the first containing plate 22 and the second containing plate 23 form an included angle.

[0049] With reference to Figure 2 , Figure 5 and Figure 6 , the surface of the locking strip 27 is provided with a locking inclined surface 272, the distance between the locking inclined surface 272 and the limiting plate 3 gradually decreases along the direction from the locking strip 27 to the bottom wall of the locking groove 271, and the locking inclined surface 272 is located on the moving path of the limiting plate 3. When the moving block 31 is located in the movable groove 261, the limiting plate 3 drives the locking strip 27 to move through the locking inclined surface 272, so that the locking strip 27 can be inserted into the locking groove 271, and the first containing plate 22 and the second containing plate 23 can be fixed to each other.

[0050] With reference to Figure 2 and Figure 5 , the surface of the baffle 2 close to the ground is provided with a dehumidification groove 4, and the groove wall of the dehumidification groove 4 is fixedly connected with a clamping block 41. A dehumidification bag 42 capable of adsorbing moisture is placed in the dehumidification groove 4. The groove wall of the placing groove 12 is provided with a through hole 43 communicating with the mounting groove 11, and when the baffle 2 is located in the placing groove 12, the through hole 43 communicates with the dehumidification groove 4.

[0051] With reference to Figure 2 and Figure 5The groove wall of the dehumidification tank 4 is fixedly connected with a sliding spring 44, the surface of the sliding spring 44 is fixedly connected with a sliding plate 45, and the surface, away from the sliding spring 44, of the sliding plate 45 is fixedly connected with a sliding block 46. The sliding spring 44 drives the sliding plate 45 to abut against the dehumidification bag 42, and the sliding block 46 abuts against the side of the dehumidification bag 42, which is close to the through hole 43. When the sliding plate 45 abuts against the dehumidification bag 42, the sliding spring 44 is in a non-stressed state; when the sliding plate 45 does not abut against the dehumidification bag 42 and the sliding block 46 does not abut against the dehumidification bag 42, the sliding spring 44 is in a compressed state, at which time the limiting plate 3 is fixed by friction force, so as to avoid that the sliding spring 44 drives the moving block 31 to slide in the active groove 261.

[0052] With reference to Figure 5 The sliding plate 45 extends into the active groove 261, and the sliding plate 45 is located on the moving path of the moving block 31 in the active groove 261. When the moving block 31 is located in the active groove 261, the moving block 31 pushes the sliding plate 45 to move, so that the sliding plate 45 does not abut against the dehumidification bag 42, and the sliding block 46 does not abut against the dehumidification bag 42. Therefore, the worker can directly pull out the dehumidification bag 42 from the dehumidification tank 4, so as to realize replacement of the dehumidification bag 42.

[0053] The implementation principle of the preassembled transformer substation is as follows: the worker slides the limiting plate 3 to take out the limiting plate 3 from the containing groove 13, at which time the baffle 2 extends out of the placing groove 12. Then the worker slides the limiting plate 3 to enable the limiting strip 32 to be separated from the two limiting holes 254, slides the guide block 25, and rotates the first containing plate 22 and the second containing plate 23 until the guide strip 24 is inserted into the recess 241, and the guide hole 251 is communicated with the guide groove 252, so that the rainwater falls from the falling hole 253. At this time, the worker slides the limiting plate 3 to enable the limiting plate 3 to drive the locking strip 27 to be inserted into the locking groove 271 through the locking inclined surface 272. At this time, the limiting plate 3 abuts against the surface, close to the bottom wall of the containing groove 21, of the first containing plate 22, so as to complete the opening of the first containing plate 22 and the second containing plate 23.
