[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined. Example

[0039] like Figure 1-Figure 3As shown, an earthquake-resistant box-type substation suitable for harsh environments is provided, including a substation body 100 and a base 101 arranged at the bottom of the substation body 100, the base 101 is fixed to a pedestal by bolts, side panels are fixedly connected on both sides of the base 101, power units 200 are symmetrically arranged on both sides of the side panels, and flip support members 120 are arranged below the center of the power units 200 on both sides, the flip support members 120 are rotatably connected to the side panels, and the power unit 200 is used to drive the flip support members 120 to flip counterclockwise when the substation body 100 shakes violently, and limit parts 400 pre-buried in the ground are arranged on both sides of the base 101, The limiting part 400 is used to limit the rotation of the flip support 120. The flip support 120 on both sides supports the substation body 100. A lifting mechanism 130 is arranged between the limiting parts 400 on both sides. The lifting mechanism 130 is used to push out the pushing part 300 arranged on the inner side of the flip support 120. The pushing part 300 is used to squeeze the airbag 110 arranged on the side panel. The airbag 110 fills the gap between the flip support 120 and the side panel, so as to use the flip support 120 to provide support for the substation body 100, thereby preventing the substation body 100 from being skewed after the foundation pit at the bottom of the substation body 100 is broken.

[0040] It can be seen that when the substation body 100 shakes violently, the power unit 200 is used to release the flip support 120, so that the flip support 120 rotates counterclockwise and is fixed by the limit unit 400 pre-buried in the ground, so that the substation body 100 is supported by the flip support 120 on both sides, and the pushing unit 300 squeezes the airbag 110 to fill the gap, thereby preventing the substation body 100 from tilting after the base at the bottom is broken, thereby protecting the substation body 100.

[0041] Therefore, based on the above structure, combined with Figure 4 The structure of the power unit 200 is further disclosed. The power unit 200 includes a winding disc 210 and a piston plate 220. A traction rope is wound around the winding disc 210, and the winding disc 210 drives the flip support 120 to rotate through a transmission shaft. The other end of the traction rope is fixedly connected to a push plate 320. In order to make the flip support 120 rotate counterclockwise when violent shaking occurs, for this purpose, the turning support 120 is rotated counterclockwise by the turning support 120. Figure 5As shown, the piston plate 220 is slidably connected to the piston cylinder 201 fixed on the side plate, and the piston cylinder 201 is spliced ​​in two halves, and the two halves of the piston cylinder 201 are connected by rotation at one end and magnetically matched at the other end. The top of the piston cylinder 201 is connected to the oblique straight pipe, and a storage tank 202 is arranged at the top of the oblique straight pipe. A plurality of weighted balls 230 are arranged inside the storage tank 202. When the substation body 100 shakes violently, the weighted balls 230 in the storage tank 202 fall into the piston cylinder 201. The weighted balls 230 and the shaking of the substation body 100 and the impact force generated by the collision of the plurality of auxiliary wheels 203 make the piston plate 220 drive the traction rope to move downward, and the piston cylinder 201 releases the traction rope and drives the flip support 120 to flip, thereby lowering the center of gravity of the substation body 100 as a whole through the flipping of the flip support 120, and making the substation body 100 more stable.

[0042] When the shaking of the transformer substation body 100 stops, the two halves of the piston cylinder 201 are separated, and the weight ball 230 is placed in the storage tank 202 for reuse.

[0043] It should be noted that the winding disk 210 can not only be directly connected to the flip support 120 through the transmission shaft, but also the winding disk 210 and the flip support 120 can be connected through a reduction gear. This connection method is a prior art and will not be described in detail here.

[0044] Considering that when the traction rope is pulled by the piston plate 220, if the traction rope is excessively tilted, the friction between the traction rope and the piston cylinder 201 is likely to increase, which is not conducive to the release of the flip support 120. Therefore, an auxiliary wheel 203 is provided beside the piston cylinder 201, and the auxiliary wheel 203 is flush with the top of the piston cylinder 201, and a plurality of balls are arranged in an array at the top of the piston cylinder 201 and the sliding connection with the traction rope, so that the traction rope can be kept level when it is pulled, and the balls can reduce the wear of the traction rope and increase the service life of the traction rope.

[0045] In addition, in order to prevent the traction rope from being stretched when the substation body 100 does not shake violently (that is, the weight ball 230 in the oblique branch pipe will not fall into the piston cylinder 201), a stopper (such as silicone) is provided near the connection between the oblique branch pipe and the piston cylinder 201, and the stopper is used to prevent the auxiliary wheel 203 from sliding. When the weight ball 230 shakes excessively, the weight ball 230 can break through the limit of the stopper and slide from the oblique branch pipe into the piston cylinder 201, thereby applying pressure to the piston plate 220, causing the flip support 120 to flip counterclockwise.

[0046] When the violent shaking causes the flip support 120 to rotate until it is fixed by the limit part 400, the support of the flip support 120 on both sides of the substation body 100 remains stable. Figure 7As shown, supporting feet are arranged on both sides of the bottom of the flip support 120, and a fixing block 121 is arranged inside the supporting feet. The fixing block 121 is in an inclined shape, and a plug hole is opened in the fixing block 121 to fix the fixing block 121 later.

[0047] In order to fix the fixed block 121, the specific structure of the limiting part 400 is disclosed below. The limiting part 400 includes a limiting rod 410 and an auxiliary top plate 420. The front end of the limiting rod 410 is arc-shaped, and the rear end is fixedly connected to the auxiliary top plate 420. The limiting rod 410 and the auxiliary top plate 420 are slidably connected to the fixing ring. The bottom of the fixing ring is fixedly connected to the bottom plate. The auxiliary top plate 420 passes through the fixing ring and fits the upper surface of the bottom plate. In addition, a second spring 401 is sleeved on the limiting rod 410. One end of the second spring 401 is fixedly connected to the fixing ring, and the other end is fixedly connected to the connection between the limiting rod 410 and the auxiliary top plate 420. In this way, when the flip support 120 flips to the maximum extent, the fixing block 121 gradually squeezes the limiting rod 410, and the front end of the limiting rod 410 slides along the inclined surface of the fixing block 121 until the limiting rod 410 is completely pushed outward, and the limiting rod 410 is inserted into the socket under the elastic action of the second spring 401, thereby fixing the flip support 120.

[0048] It should be disclosed that: in a normal state, the flip support 120 is perpendicular to the ground, and a magnet is embedded in the side panel, and the magnet is used to absorb the iron block provided at the corresponding position of the flip support 120.

[0049] Furthermore, when the substation body 100 shakes left and right, although the flip supports 120 on both sides can provide support for the substation body 100, the two ends of the flip supports 120 are rotatably connected to the side panels and the limiting plug rods 410 respectively. In this way, there will be an angle between the flip supports 120 and the side panels on both sides during shaking. The gap at the angle makes the substation body 100 have a shaking range, which is not conducive to maintaining the stability of the substation body 100.

[0050] Therefore, the substation body 100 disposed on the side plate is used to protect the substation body 100 under normal conditions, and when the substation body 100 shakes violently, the gap between the flip support 120 and the side plate is filled to limit the shaking of the substation body 100. Figure 6As shown, the specific structure of the push part 300 is disclosed. The push part 300 includes a push rod 310 and a push plate 320. The push rod 310 is fixed on the top of the push plate 320. The push plate 320 is slidably connected to the auxiliary block fixed on the inner side of the flip support 120, and a baffle is coaxially connected to the push plate 320. A first spring 301 fixedly connected to the baffle is sleeved on the push plate 320, and the other end of the first spring 301 is against the auxiliary block. When the flip support 120 rotates, under the influence of centrifugal force, the push rod 310 and the push plate 320 will move as a whole to the opposite side of the connection between the flip support 120 and the side plate. The purpose of doing this is to move the push rod 310 to the lower side of the airbag 110 in the horizontal direction, so that the airbag 110 is squeezed after the push plate 320 is ejected, thereby filling the gap.

[0051] In order to squeeze the airbag 110 so that the gap is filled, Figure 6 Based on Figure 8 As shown, the lifting mechanism 130 is slidably connected to the bottom plate, and an auxiliary column 102 fixedly connected to the bottom plate is arranged below the lifting mechanism 130, and the two sides of the lifting mechanism 130 are slidably connected to the limit bars 103, and the limit bars 103 are fixedly connected to the bottom plate. Those skilled in the art can know that: the lifting mechanism 130 has the same principle as the traditional lifting device, and the lifting mechanism 130 is composed of a plurality of connecting rods, and the plurality of connecting rods are rotatably connected to each other, which is common knowledge and will not be described in detail here.

[0052] When the auxiliary top plates 420 on both sides squeeze the lifting mechanism 130 inward, the limit strip 103 is used to keep the lifting mechanism 130 stable during the lifting and lowering process of the lifting mechanism 130, and the bottom of the push plate 320 slides on the top of the lifting mechanism 130, and the lifting mechanism 130 moves upward and cooperates with the elastic potential energy of the first spring 301 to push the push plate 320 to move, so that the push rod 310 squeezes the airbag 110, and the airbag 110 expands to fill the gap, and the side plate and the flip support 120 are supported by the airbag 110 (a triangular support is formed between the flip support 120, the airbag 110 and the side plate to limit the left and right shaking of the substation body 100).

[0053] At the same time, in order to ensure that the pushing plate 320 continues to squeeze the airbag 110, the pushing plate 320 does not move in the opposite direction due to the reaction force between the airbag 110 and the pushing plate 320 during shaking, thereby causing the substation body 100 to shake.

[0054] To this end, combined Fig. 9As shown, a groove is opened in the middle of the push plate 320, and an elastic sheet 302 is fixedly connected inside the groove. When the elastic sheet 302 is fixed to the push plate 320, the elastic sheet 302 extends outward to support the auxiliary block. When the substation body 100 shakes left and right, the elastic sheet 302 can support the auxiliary block, thereby limiting the reverse movement of the push plate 320, thereby achieving the squeezing of the airbag 110, ensuring the stability of the substation body 100, and improving the seismic performance of the substation body 100.

[0055] At the same time, after the push plate 320 is restricted, it will not push the lifting mechanism 130 in the reverse direction, so that it can ensure that the limiting rod 410 always fixes the fixing block 121. When the airbag 110 stops shaking, the elastic sheet 302 is pushed into the groove to make the push plate 320 move in the reverse direction. The push plate 320 squeezes the lifting mechanism 130, thereby pushing out the limiting rods 410 on both sides, thereby restoring the device to its initial state for reuse.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
