DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0018] As shown in Figures 1-9, the present invention has the following specific embodiments. Example

[0019] A transformer protection device includes a transformer 9 and further includes: Support rod 1, four support rods 1 are provided, and are respectively located near the four corners of transformer 9. A fixing flange 101 is fixedly connected to the lower end of support rod 1, and a plurality of groups of fixing seats 105 are fixedly connected to support rod 1. An arc-shaped slide bar 106 is fixedly connected between each group of fixing seats 105. Two connecting feet 103 are fixedly connected to the position near the lower edge of support rod 1. The two connecting feet 103 are distributed at 90 degrees. Two connecting sleeves 107 are fixedly connected at the position, and the two connecting sleeves 107 are aligned with the connecting pin 103 up and down; The first fence 2 includes a connecting rod 201 and a plurality of transverse plates 202. The plurality of transverse plates 202 are fixedly connected to the connecting rod 201. The transverse plates 202 have sliding holes 203 formed therein. The sliding holes 203 are slidably matched with the arc-shaped sliding rod 106. The protection component 4 includes a connecting seat 5 and a connecting plate 6. A connecting square hole 501 is horizontally opened in the connecting seat 5. A fixing groove 502 is opened on the connecting seat 5. The fixing groove 502 is communicated with the inside of the connecting square hole 501. The connecting plate 6 cooperates with the connecting square hole 501 and the connecting foot 103. A hinged ear 503 is fixedly connected to the front end of the connecting seat 5. Connecting holes 504 are opened on the inner walls of both sides of the hinged ear 503. A connecting shaft 505 is rotatably installed in the connecting hole 504. A protection rod 506 is fixedly connected to the connecting shaft 505. An energy absorbing torsion spring 507 is symmetrically sleeved on the connecting shaft 505. One end of the energy absorbing torsion spring 507 is fixedly connected to the inner wall of the connecting hole 504, and the other end of the energy absorbing torsion spring 507 is fixedly connected to the protection rod 506.

[0020] In this embodiment, the connecting plate 6 cooperates with the connecting square hole 501, and the two connecting seats 5 can be connected together by the connecting plate 6. By controlling the number of the connecting plates 6 and the connecting seats 5, the overall length of the protective assembly 4 can be controlled, so that the protective assembly 4 can be connected between the support rods 1 with different spacings, and transformers 9 of different sizes can be enclosed. The protective rod 506 connected to the connecting seat 5 by the hinged ear 503 is vertically upward, and multiple vertical fences are formed. The first fence 2 is rotatably connected to the support rod 1, and the gap between the fence composed of the support rod 1 and the protective rod 506 can be filled, thereby effectively preventing outsiders from approaching the transformer 9 at will. The first fence 2 is rotatably installed on the arc sliding bar 106. The first fence 2 can be rotated at a certain angle to expose the gap between the fence composed of the support rod 1 and the protective rod 506. The maintenance personnel can enter the enclosure through the gap to perform maintenance and other operations on the transformer 9. When foreign objects hit the device, Taking a vehicle as an example, when the vehicle hits the vertical fence formed by the guard bar 506, the guard bar 506 contacts the vehicle and is subjected to force. 506 is connected to the hinged ear 503 by rotation through the connecting shaft 505, and the protective rod 506 rotates when subjected to force. The rotation of the guard bar 506 will compress the energy absorbing torsion spring 507, thereby converting a certain impact force into the torsion of the energy absorbing torsion spring 507, providing a certain buffer for the vehicle and the guard bar 506 itself, and avoiding direct hard collision between the vehicle and the device. The protective rod 506 will be in contact with the telescopic blocking rod 7 after rotating and tilting to a certain extent, and then the protective rod 506 will contact with the telescopic blocking rod 7 to prevent the protective rod 506 from continuing to rotate. At this time, the protective rod 506 is in an inclined state, and the impact force of the vehicle has not been completely reduced. At this time, the chassis of the vehicle will be lifted up by the protective rod 506, and a part of the impact force of the vehicle will be decomposed into upward gravitational potential energy, further reducing the impact force, thereby effectively reducing the impact force and reducing the damage to the vehicle and the device itself. Example

[0021] As shown in FIGS. 1 , 3 and 9 , a plugging cone hole 102 is provided at the upper end of the support rod 1, a shielding top plate 8 is provided above the transformer 9, plugging cone columns 801 are connected to the bottom of the shielding top plate 8 near the four corners through magnets, and the plugging cone columns 801 are plugged into the plugging cone holes 102, a telescopic blocking rod 7 is provided between the two support rods 1, the telescopic blocking rod 7 cooperates with the connecting sleeve 107, a connecting through hole 701 is provided near the two ends of the telescopic blocking rod 7, a through hole is provided on the connecting sleeve 107, a bolt is provided in the through hole, and the bolt cooperates with the connecting through hole 701.

[0022] In this embodiment, the plug-in cone column 801 is a cone with a small bottom and a large top, which cooperates with the plug-in cone hole 102. After the plug-in cone column 801 is inserted into the plug-in cone hole 102 and the plug-in cone column 801 is inserted into the plug-in cone hole 102 by downward pressure, the friction force will fix the plug-in cone column 801 inside the plug-in cone hole 102, so that the shielding top plate 8 is supported above the transformer 9 to prevent rainwater from directly contacting the transformer 9 body. The shielding top plate 8 and the plug-in cone column 801 are connected by magnets. The shielding top plate 8 is made of iron as a whole. A strong magnet is embedded and installed at the upper end of the plug-in cone column 801, so that the position of the plug-in cone column 801 can be changed according to the support rod 1, and the shielding top plate 8 can also be lifted. In windy weather, the shielding top plate 8 needs to be removed to prevent the shielding top plate 8 from being blown away. The telescopic blocking rod 7 is telescopic as a whole, so that it can be installed between adjacent support rods 1 with different spacings. After the two ends of the telescopic blocking rod 7 are respectively inserted into the connecting sleeve 107, the telescopic blocking rod 7 and the connecting sleeve 107 can be fixedly connected by bolts, so that the telescopic blocking rod 7 is fixed between the two support rods 1 to form a support rod, which supports the rotating protection rod 506 and prevents the arc-shaped sliding rod 106 from being rotated at an excessively large angle under force and contacting the transformer 9. Example As shown in Figures 2, 3, 4 and 5, a limiting groove 204 is provided in the transverse plate 202, a limiting pin 205 is slidably installed in the limiting groove 204, a spring pad 206 is fixedly connected to the limiting pin 205, a return spring 207 is sleeved on the limiting pin 205, a pull ring 208 is fixedly connected to the upper end of the limiting pin 205, a limiting block 3 is symmetrically fixedly connected to the support rod 1, a limiting hole 301 is provided in the limiting block 3, the limiting hole 301 cooperates with the limiting pin 205, a first limiting block 508 is symmetrically fixedly connected to the connecting shaft 505, a second limiting block 509 is fixedly connected to both sides of the hinged ear 503, and the first limiting block 508 and the second limiting block 509 cooperate with each other.

[0023] In this embodiment, the return spring 207 can provide a certain thrust for the spring washer 206. The spring washer 206 is subjected to the thrust and drives the limit pin 205 to move down and insert into the limit hole 301, thereby fixing the position of the first fence 2 to prevent the first fence 2 from rotating at will. Pulling the pull ring 208 drives the limit pin 205 to move up, so that the limit pin 205 can be moved out of the limit hole 301, thereby releasing the restriction on the first fence 2. At this time, the first fence 2 can rotate to a certain angle to expose the gap between the support rod 1 and the protective rod 506 to form a fence, so that maintenance personnel can enter the enclosure. The first limit block 508 and the second limit block 509 cooperate with each other to limit the rotation angle of the connecting shaft 505, and cooperate with the energy-absorbing torsion spring 507 to keep the protective rod 506 in an upright state. Example

[0024] As shown in FIGS. 2, 5 and 6, nuts 601 are symmetrically embedded and installed on the connecting plate 6, a connecting groove 104 is provided in the connecting foot 103, a through hole is provided on the connecting foot 103, a bolt is provided in the through hole, and the bolt and the nut 601 cooperate with each other.

[0025] In this embodiment, the connecting groove 104 cooperates with the connecting plate 6. After one end of the connecting plate 6 is inserted into the connecting groove 104, the connecting plate 6 can be fixedly connected to the connecting foot 103 by passing a bolt through the nut 601, thereby fixing the first fence 2 and the support rod 1 together. Similarly, the connecting plate 6 can be fixedly connected to the connecting seat 5 by passing a bolt through the fixing groove 502 and the nut 601. The fixing groove 502 is a long square groove, which can control the insertion depth of the connecting plate 6 and adjust the distance between the two connecting seats 5, thereby controlling the density of the protective rod 506.

[0026] The working principle and use process of the present invention: When in use, the support rod 1 needs to be fixed by the fixing flange 101. The first fence 2 is fixed near the four corners of the transformer 9, and then the number of the connecting seat 5 and the connecting plate 6 is adjusted according to the spacing between the adjacent support rods 1, the length of the first fence 2 is controlled, and the first fence 2 is fixed between the adjacent support rods 1 by bolts to enclose the transformer 9, and then the telescopic blocking rod 7 is inserted into the connecting sleeve 107 and fixed by bolts, and then the plug-in cone column 801 is respectively inserted into the plug-in cone hole 102, and the shielding top plate 8 is adsorbed and installed on the upper end of the plug-in cone column 801, and the installation of the device can be completed. When the maintenance personnel need to inspect the transformer 9, they pull the pull ring 208 to drive the limit pin 205 to move up, so that the limit pin 205 can be moved out of the limit hole 301, thereby releasing the restriction on the first fence 2. At this time, the first fence 2 can be rotated to a certain angle to expose the gap between the fence composed of the support rod 1 and the protective rod 506. Through the gap, maintenance personnel can climb over the telescopic barrier 7 and enter the enclosure to perform maintenance operations on the transformer 9.
