[0003] With the continuous advancement of power grid construction, the application scope of European-style substations is becoming more and more extensive. They are not only used in urban centers, but also frequently appear in some construction sites and suburban areas. The changeable geographical environment in these areas has brought new challenges to the installation and maintenance of substations. At present, in order to solve the stability problem of European-style substations in complex environments, the existing technical means mainly include placing pads directly on the ground to adjust the height of the substation box, and pouring cement columns on site to support the substation. In addition, there are also ways to use fixed feet and other auxiliary support components to adjust the flatness of the foundation and maintain the stability of the substation.

[0004] Regarding the above-mentioned related technologies, there are many inconveniences in the actual application process. For example, when using pads, it is necessary to place pads of different heights according to the unevenness of the ground. The operation is complicated and it is not easy to adjust to the precise level; and the method of pouring cement columns on site is time-consuming, costly, and inconvenient for later maintenance.

The support frame 2 is located at the lower end of the transformer box 1, the control seat 3 and the several support seats 4 are installed at the lower end of the support frame 2, and the control seat 3 is located in the middle of the support frame 2. This embodiment takes four support seats 4 as an example. The four support seats 4 are respectively located at the four corners of the support frame 2, and a connecting seat 10 is installed between the support seat 4 and the control seat 3.

[0044] Reference Figure 2A telescopic seat 5 is installed in the support seat 4, and a telescopic groove 41 for the telescopic seat 5 to slide in the vertical direction is opened on the lower end surface of the support seat 4. The telescopic seat 5 has a storage state and a use state: when the telescopic seat 5 is in the storage state, the telescopic seat 5 is completely located in the telescopic groove 41; when the telescopic seat 5 is in the use state, the telescopic seat 5 extends out of the telescopic groove 41.

[0045] Reference Figure 3 A fixing member 6 is installed on the support seat 4, and the fixing member 6 slides horizontally on the fixing rod 61 on the support seat 4. A sliding groove 42 for the fixing rod 61 to slide is opened on the support seat 4. A fixing block 51 is installed on the telescopic seat 5, and a fixing groove 511 for inserting the fixing rod 61 is opened on one end surface of the fixing block 51 in the horizontal direction.

[0046] Reference Figure 3 When the telescopic seat 5 is in the storage state, the fixing rod 61 is aligned with the fixing groove 511, and the fixing rod 61 is inserted into the fixing groove 511. At this time, the telescopic seat 5 cannot slide in the vertical direction, so that the fixing member 6 fixes the telescopic seat 5 in the storage state in the support seat 4.

[0047] Reference Figure 2 and Figure 4 A control rod 7 is installed on the control seat 3, and a control groove 31 for the control rod 7 to slide vertically is opened on the lower end surface of the control seat 3. A first spring 8 is also installed in the control seat 3, one end of the first spring 8 abuts against the upper groove wall of the control groove 31, and the other end of the first spring 8 abuts against the upper end surface of the control rod 7.

[0048] Reference Figure 2 and Figure 4 Under the action of the elastic force of the first spring 8, the control rod 7 always moves toward the lower end until the control rod 7 extends out of the control groove 31.

[0049] Reference Figure 2 and Figure 4 A contact plate 9 is also installed at the lower end of the control seat 3. The contact plate 9 is connected to the control seat 3 by a shaft, and the rotation center line of the contact plate 9 is arranged in a horizontal direction. A rotation groove 91 for the control seat 3 to rotate is provided on the contact plate 9. When the control seat 3 is about to contact the ground with a certain slope, the contact plate 9 is rotated to align the angle of the contact plate 9 with the slope, so that the control seat 3 can adapt to the ground with different slopes.

[0050] Reference Figure 4A stabilizing member for fixing the abutment plate 9 is provided on the control seat 3, and the stabilizing member may be a screw or a latch (not shown in the figure). During installation, a first opening for the stabilizing member to pass through may be firstly provided on the outer wall of the abutment plate 9, and then a plurality of second openings may be provided on the side wall of the control seat 3 accordingly. As the abutment plate 9 rotates to different positions, the stabilizing member may pass through the first opening and be plugged into the second opening.

[0051] Reference Figure 4 and Figure 5 An unlocking member 11 is installed on the connecting seat 10. The unlocking member 11 is an unlocking rod 111 that slides in the horizontal direction. An unlocking groove 101 is opened on the connecting seat 10 for the unlocking rod 111 to slide. One end of the unlocking groove 101 is connected to the control groove 31, and the other end of the unlocking groove 101 is connected to the telescopic groove 41.

[0052] Reference Figure 4 and Figure 5 A first guide slope 1111 is provided on the unlocking rod 111, and a second guide slope 611 is provided on the fixing rod 61. When the control rod 7 moves toward the upper end, the control rod 7 will abut against the first guide slope 1111 of the unlocking rod 111. At this time, under the action of the first guide slope 1111, the unlocking rod 111 slides toward the support seat 4 until the unlocking rod 111 abuts against the second guide slope 611 of the fixing rod 61. At this time, under the action of the second guide slope 611, the fixing rod 61 slides toward the direction away from the bottom of the fixing groove 511 until the fixing rod 61 is out of the fixing groove 511.

[0053] Reference Figure 4 and Figure 5 When the fixing rod 61 is out of the fixing groove 511, the support seat 4 no longer fixes the telescopic seat 5. Under the action of the gravity of the telescopic seat 5, the telescopic seat 5 slides away from the support seat 4 until the telescopic seat 5 abuts against the ground.

[0054] Reference Figure 2 and Figure 3 A locking assembly 12 is also installed on the support seat 4, and the locking assembly 12 includes a locking cylinder 121, a locking rod 122 and a starting rod 123, wherein the locking cylinder 121 includes a locking cylinder body 1211 and a locking piston rod 1212, and a placement groove 43 for placing the locking cylinder body 1211 is opened on the support seat 4, and the locking rod 122 is welded to the side of the locking piston rod 1212 away from the locking cylinder body 1211. A moving groove 44 for the locking rod 122 and the locking piston rod 1212 to slide horizontally is opened on the support seat 4, and a plurality of locking grooves 52 for inserting the locking rod 122 are opened in the vertical direction on the telescopic seat 5.

[0055] Reference Figure 2 and Figure 3The starting rod 123 is located on the telescopic seat 5. A starting groove 53 for the starting rod 123 to slide in the vertical direction is provided on the lower end surface of the telescopic seat 5. A locking switch 13 is installed on the upper groove wall of the starting groove 53.

[0056] Reference Figure 2 and Figure 3 , the telescopic seat 5 moves in the direction away from the supporting seat 4. When the telescopic seat 5 abuts against the ground, the starting rod 123 will be pushed into the starting groove 53 by the ground, and the starting rod 123 abuts against the locking switch 13. At this time, the locking cylinder 121 drives the locking rod 122 to move toward the corresponding locking groove 52. When the locking rod 122 is inserted into the locking groove 52, the telescopic seat 5 is fixed on the supporting seat 4, thereby achieving the effect that the fixed component fixes the telescopic seat 5 in use state on the supporting seat 4.

[0057] Reference Figure 2 and Figure 3 In order to prevent the actuating rod 123 from being accidentally used in an idle state and causing the actuating rod 123 to abut against the locking switch 13, a second spring 14 is provided on the telescopic seat 5, one end of the second spring 14 abuts against the upper groove wall of the actuating groove 53, and the other end of the second spring 14 abuts against the upper end surface of the actuating rod 123. Under the action of the elastic force of the second spring 14, the actuating rod 123 always has a tendency to move downward until the actuating rod 123 extends out of the actuating groove 53. Under the action of the second spring 14, the actuating rod 123 can be pushed downward in a normal placement state, thereby reducing the occurrence of accidental use of the actuating rod 123.

[0058] Reference Figure 2 In an optional embodiment, the substation further includes a water accumulation sensor 23 and a lifting device 24, wherein the water accumulation sensor 23 is fixed to the inner side of the support frame 2, the lifting device 24 is arranged on the support frame 2, and the water accumulation sensor 23 is connected to the lifting device 24. When water rises on rainy days or other occasions, the water accumulation sensor 23 senses water accumulation and can send a signal to control the lifting device 24 to start, thereby moving the substation upward to prevent water from entering the substation and reduce safety hazards.

[0059] Reference Figure 6Specifically, the lifting device 24 includes a screw 241, a threaded barrel 242 and a power piece 243. A mounting rod 21 is provided between two adjacent support seats 4. The mounting rod 21 can also be a rectangular metal rod. The mounting rod 21 is located below the support frame 2. The lower end of the screw 241 is rotatably connected to the mounting rod 21, and the threaded barrel 242 is slidably provided on the support seat 4 up and down. A block is provided on the outer wall of the threaded barrel 242, and a slot is provided on the support seat 4 to cooperate with the block to ensure that the threaded barrel 242 maintains vertical stability when sliding up and down. The upper end of the screw 241 is inserted into the threaded barrel 242 and is threadedly connected to the inner wall of the threaded barrel 242. The power piece 243 is used to drive the screw 241 to rotate, thereby driving the threaded barrel 242 to move upward. Multiple screws 241 and threaded barrels 242 can be provided along the circumference of the transformer box 1, and the transformer box 1 is lifted upward by multiple threaded barrels 242. In this embodiment, the mounting rods 21 are respectively provided at the left and right ends of the transformer box 1 , and screw rods 241 and threaded barrels 242 are provided at both ends of each mounting rod 21 , so as to stably support the box body 16 .

[0060] Reference Figure 6 In this embodiment, the power member 243 is a control motor 244, which is fixed to the lower surface of the mounting rod 21, and its output end is vertically passed through the mounting rod 21 and connected to the screw rod 241. The control motors 244 and the screw rods 241 are arranged one by one, and all the control motors 244 are connected to the water accumulation sensor 23, so that when the phase changing box needs to be lifted, the four threaded cylinders 242 can be synchronously controlled to move upward.

[0061] Reference Figure 6 In order to improve the stability of the transformer box 1 when it moves up and down, a slot 151 for the upper end of the threaded tube 242 to be inserted is also provided at the bottom of the transformer box 1. The transformer box 1 includes a box body 16 and a base 15. The box body 16 is fixed to the center of the base 15. The upper end of the box body 16 is provided with a sloping roof for water blocking. Furthermore, a plurality of guide rods 17 are fixed to the lower surface of the base 15 by bolts, and a guide seat 22 is fixed to the inner side wall of the support frame 2. A guide hole 221 is provided on the guide seat 22 that passes through the upper and lower parts. The guide rod 17 slides through the guide hole 221. When the transformer box 1 moves up and down, the cooperation between the guide rod 17 and the guide hole 221 can increase the stability of the transformer box 1.

[0062] Reference Figure 6In an optional embodiment, a floating rod 25 and a waterproof cloth 26 are also provided on the base 15 of the transformer box 1. Specifically, a receiving groove 152 is provided on the base 15, and the receiving groove 152 is provided along the circumference of the box body 16. The floating rod 25 is provided in the receiving groove 152, which is configured as a hollow round rod and adopts a lightweight material such as PVC. The waterproof cloth 26 is fixed between the floating rod 25 and the bottom wall of the receiving groove 152, and can be received in the receiving groove 152 together with the floating rod 25. When the accumulated water flows into the receiving groove 152 at a high level, the floating rod 25 will be driven to move upward, so that the waterproof cloth 26 surrounds the circumference of the box body 16 for waterproofing. When the accumulated water recedes, the waterproof cloth 26 and the floating rod 25 can be re-received in the receiving groove 152, which will not affect the use of the transformer box 1.

[0063] The implementation principle of a European-style substation in an embodiment of the present application is as follows: when installing the substation, first put the support frame 2 in a horizontal state, and then move the control seat 3 toward the ground until the abutment plate 9 abuts against the ground. At this time, the control rod 7 is pressed and moves toward the upper end. With the cooperation of the first guide slope 1111 and the second guide slope 611, the fixed rod 61 is disengaged from the fixed groove 511, and then the telescopic seat 5 descends under the action of gravity.

[0064] When the telescopic seat 5 falls to the ground, the starting rod 123 is pressurized and rises, and the starting rod 123 abuts against the locking switch 13. The locking cylinder 121 drives the locking rod 122 to insert into the locking groove 52. At this time, the telescopic seat 5 in use is fixed on the support seat 4, which can achieve the support frame 2 to be adjusted to the surface horizontal state under different terrains. In particular, when the ground is uneven, the telescopic seats 5 in the four support seats 4 can be extended to different lengths, and when they abut against the ground respectively, they can be fixed separately without manual adjustment, which improves the adaptability of the substation installation and can also install the substation quickly and conveniently.

[0065] Then, the transformer box 1 is placed on the support frame 2 by hoisting, and the guide rod 17 is aligned with the guide hole 221 and inserted, and at the same time, the upper end of the threaded cylinder 242 is inserted into the slot 151. When the water accumulation sensor 23 senses water accumulation, the control motor 244 is started, thereby driving the threaded cylinder 242 to move upward through the screw 241 to lift the transformer substation, and when the water level is higher and submerges the base 15 of the box body 16, it can drive the floating rod 25 to float, thereby protecting the bottom of the transformer box 1 through the waterproof cloth 26.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
