Description

Technical Field

[0001] This utility model belongs to the field of power plant facility anti-collision technology, and in particular relates to an anti-collision structure for power plant facilities. Background Technology

[0002] In power systems, power plant facilities (especially core equipment such as transformers) are crucial to ensuring stable power transmission, and their operating status directly affects the reliability of regional power supply. However, power plants usually require outdoor installation areas, and equipment such as transformers are exposed to complex environments for a long time, facing various collision risks. Currently, most power plants only rely on basic fences or simple metal frames to protect transformers. When such protective structures encounter external impacts, such as collisions caused by misoperation of maintenance vehicles, the impact force will be directly transmitted to the transformer body, which can easily lead to deformation of the transformer shell, loosening of terminals, and in severe cases, damage to the internal iron core or windings, causing oil leakage, short circuit tripping and other faults in oil-immersed transformers, resulting in long-term power outages. Therefore, a collision protection structure for power plant facilities is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-collision structure for power plant facilities. By setting up an anti-collision mechanism, specifically, when an external impact occurs, the anti-collision plate slides along the sliding track of the fixed frame via a trapezoidal groove. In the initial stage, it contacts the damping rod, compressing the first spring and converting part of the impact force into elastic potential energy, completing the first layer of buffering. If the impact force is large, the anti-collision plate continues to slide, driving the second hinge block to move. Through the hinge rod, the first hinge block and the sliding block slide along the inclined slide rod, compressing the second spring. The inclined slide rod disperses the force, and the second spring absorbs energy and can be reset, achieving the second layer of protection. This reduces the impact force directly transmitted to the fixed frame and the transformer, effectively protecting the transformer body from impact damage. This solves the problem that the protection of transformers in existing power plants relies only on basic fences or simple metal frames. When such protective structures encounter external impacts, such as collisions caused by misoperation of maintenance vehicles, the impact force is directly transmitted to the transformer body, which can easily lead to deformation of the transformer shell, loosening of terminals, and in severe cases, damage to the internal iron core or windings, causing oil leakage, short circuit tripping, and other faults in oil-immersed transformers, resulting in long-term power outages.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an anti-collision structure for power plant facilities, comprising a support plate on which a transformer is mounted, and further comprising: an anti-collision mechanism disposed on the top of the support plate; an anti-deformation mechanism disposed on the top of the support plate; the anti-collision mechanism comprising protective components disposed on the front and back of the transformer; and a buffer component disposed inside the protective components of the support plate; the protective components comprising two fixing frames respectively mounted on the front and back of the transformer, with damping rods installed on the inner sides of each fixing frame, and springs wound around the outer surfaces of each damping rod.

[0006] Furthermore, anti-collision plates are provided on the opposite sides of the two fixed frames, and sliding rails are installed at the four corners of the inner sides of the two fixed frames. Slide grooves are provided at the four corners of the two anti-collision plates. All four sliding rails and slide grooves are trapezoidal. The anti-collision plates slide along the sliding rails via the four slide grooves. The sliding rails are made of high-strength alloy material, and their trapezoidal structure is precisely calculated and processed. The width of the upper base of the trapezoid is slightly smaller than the opening width of the slide groove, while the width of the lower base matches the inner width of the slide groove. This structural design can effectively prevent the anti-collision plates from falling off during the sliding process.

[0007] Furthermore, two sliding rods are installed inside each of the two fixed frames, and springs are wound around the outer surface of each of the four sliding rods. The four sliding rods are arranged in pairs, and the two pairs of sliding rods are installed inside the two fixed frames respectively. Both sliding rods are inclined. The inclined arrangement of the sliding rods can maximize the dispersion of impact force while ensuring that the sliding block slides smoothly on the sliding rods. The two ends of the sliding rods are connected to the inner sidewall of the fixed frame by welding.

[0008] Furthermore, the buffer assembly includes several sliding blocks, which are respectively disposed inside the two fixed frames. The sliding blocks slide on the outer surfaces of the four slide rods. A hinge block is installed on the side of each sliding block that is far away from each other. The sliding blocks are arranged in pairs, with a total of four groups. The four groups of sliding blocks slide on the outer surfaces of the four slide rods respectively.

[0009] Furthermore, several hinge blocks are installed on the side of each of the two anti-collision plates that are close to each other. A hinge rod is rotatably connected between several hinge blocks and several hinge blocks. Protective rods are provided on the left and right sides of the transformer. Both protective rods are fixed to the side of the two fixed frames that are close to each other. The two protective rods are inclined and are supported by the two fixed frames.

[0010] Furthermore, the anti-deformation mechanism includes four push plates, which are respectively installed on the side of the two anti-collision plates that are close to each other. Two push-in frames are installed inside the two fixed frames. When the anti-collision plate is impacted and moves towards the fixed frame, the push plate will push accordingly, transmitting the pressure to the push-in frames and airbags. The impact force is absorbed by the expansion of the airbags, preventing the fixed frames and transformer from deforming.

[0011] Furthermore, each of the two fixed frames has an airbag on its side closest to each other, and each of the two airbags has a slot on its side furthest from each other. All four slots are connected to the four push-in frames, and the inner walls of the four slots are in contact with the four push plates. The airbags are made of high-strength elastic rubber material, which has good elastic recovery ability and pressure resistance. They are filled with inert gas. The shape of the airbag is adapted to the space inside the fixed frame and is a rectangular bag-shaped structure. The surface of the airbag is provided with reinforcing ribs, which are made of the same rubber material as the airbag and are manufactured by an integral molding process. This can effectively enhance the tear resistance of the airbag and prevent the airbag from rupturing due to excessive pressure during the expansion process.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up an anti-collision mechanism, specifically, when an external impact occurs, the anti-collision plate slides along the sliding track of the fixed frame via a trapezoidal groove. In the initial stage, it contacts the damping rod, compressing the first spring and converting part of the impact force into elastic potential energy, completing the first layer of buffering. If the impact force is large, the anti-collision plate continues to slide, driving the second hinge block to move. Through the hinge rod, the first hinge block and the sliding block slide along the inclined slide rod, compressing the second spring. The inclined slide rod disperses the force, and the second spring absorbs energy and can be reset, achieving the second layer of protection. This reduces the impact force directly transmitted to the fixed frame and the transformer, effectively protecting the transformer body from impact damage and improving the reliability of the structure.

[0014] 2. This utility model incorporates an anti-deformation mechanism. Specifically, during the movement of the anti-collision plate towards the fixed frame, a pusher plate on the anti-collision plate pushes into the frame and slot to compress the airbag. After the airbag inflates, it provides support to the inside of the fixed frame, preventing the fixed frame from being deformed by impact and preventing secondary damage to the transformer caused by deformation. This reduces the deformation of the fixed frame due to impact, and the flexible support of the airbag can reduce the secondary compression of the transformer by the deformation of the fixed frame, thus improving the safety of protection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5As shown, this utility model is an anti-collision structure for a power plant facility, including a support plate 1, on which a transformer 111 is mounted. It also includes: an anti-collision mechanism 2, disposed on the top of the support plate 1; and an anti-deformation mechanism 3, also disposed on the top of the support plate 1. The anti-collision mechanism 2 includes a protective component 21, disposed on the front and back of the transformer 111; and a buffer component 22, disposed inside the protective component 21 of the support plate 1. The protective component 21 includes two fixing frames 211, respectively installed on the front and back of the transformer 111. Damping rods 212 are installed inside each of the two fixing frames 211, and springs 213 are wound around the outer surfaces of both damping rods 212. Each frame 211 has a crash plate 214 on its opposite side. Sliding rails 215 are installed at the four inner corners of each of the two fixed frames 211. Sliding grooves 216 are provided at the four corners of each of the two crash plates 214. All four sliding rails 215 and four sliding grooves 216 are trapezoidal. The crash plates 214 slide along the sliding rails 215 via the four sliding grooves 216. Two sliding rods 217 are installed inside each of the two fixed frames 211. Springs 218 are wound around the outer surface of each of the four sliding rods 217. The four sliding rods 217 are arranged in pairs, with two sets of sliding rods 217 installed inside the two fixed frames 211 respectively. Both sliding rods 217 are inclined. The buffer assembly 22 includes several sliding blocks 221, each set with... Inside the two fixed frames 211, several sliding blocks 221 slide on the outer surface of four sliding rods 217. A hinge block 222 is installed on the side of each sliding block 221 that is far apart from each other. The sliding blocks 221 are arranged in pairs, for a total of four sets. The four sets of sliding blocks 221 slide on the outer surface of the four sliding rods 217. Several hinge blocks 223 are installed on the side of each anti-collision plate 214 that is close to each other. Hinges 224 rotatably connect the hinge blocks 222 and 223. Protective rods 225 are installed on the left and right sides of the transformer 111. Both protective rods 225 are fixed to the side of each fixed frame 211 that is close to each other. The two protective rods 225 are inclined. The rod 225 is supported by two fixed frames 211. Specifically, when the external impacts the anti-collision plate 214, it slides along the sliding track 215 of the fixed frame 211 through the trapezoidal groove 216. In the initial stage, it contacts the damping rod 212 and compresses the first spring 213, converting part of the impact force into elastic potential energy, thus completing the first layer of buffering. If the impact force is large, the anti-collision plate 214 continues to slide, driving the second hinge block 223 to move. Through the hinge rod 224, the first hinge block 222 and the sliding block 221 are pushed to slide along the inclined slide rod 217, compressing the second spring 218. The slide rod 217 is inclined to disperse the force, and the second spring 218 absorbs energy and can be reset, thus achieving the second layer of protection, reducing the impact force directly transmitted to the fixed frame and the transformer, and effectively protecting the transformer body from impact damage.

[0026] The anti-deformation mechanism 3 includes four push plates 311, which are respectively installed on the sides of the two anti-collision plates 214 that are close to each other. Two push-in frames 312 are installed inside each of the two fixed frames 211. Airbags 314 are provided on the sides of the two fixed frames 211 that are close to each other, and slots 313 are provided on the sides of the two airbags 314 that are far apart from each other. All four slots 313 communicate with the four push-in frames 312, and the inner walls of the four slots 313 are in contact with the four push plates 311. Specifically, in the anti-deformation mechanism... During the movement of the impact plate 214 toward the fixed frame 211, the push plate 311 on the impact plate 214 pushes the airbag 314 into the frame 312 and the slot 313 to compress the airbag 314. After the airbag 314 is inflated, it forms support on the inside of the fixed frame 211, preventing the fixed frame 211 from being deformed by the impact, preventing the deformation from causing secondary damage to the transformer 111, reducing the deformation of the fixed frame 211 due to the impact, and at the same time, the flexible support of the airbag 314 can reduce the secondary compression of the transformer by the deformation of the fixed frame, thus improving the safety of protection.

[0027] A specific application of this embodiment is as follows: In use, when an external impact occurs to the anti-collision plate 214, the anti-collision plate 214 slides stably along the sliding track 215 on the fixed frame 211 via the trapezoidal groove 216. In the initial stage of the anti-collision plate 214 sliding inward toward the fixed frame 211 along the track, the side of the anti-collision plate 214 closest to the fixed frame 211 will first contact the damping rod 212 installed on the inner side of the fixed frame 211. The damping rod 212, utilizing its own damping characteristics, can quickly weaken the instantaneous impact force generated by the impact. At the same time, the compression of the anti-collision plate 214 on the damping rod 212 will be synchronously transmitted to the spring 213 wrapped around the outer surface of the damping rod 212. This causes the spring 213 to undergo elastic deformation. The deformation of the spring 213 converts part of the impact force into elastic potential energy, further dispersing the initial impact pressure and preventing the impact force from being directly transmitted to the fixed frame 211 and transformer 111, thus completing the first layer of buffer protection. If the external impact force is large, the anti-collision plate 214 will continue to slide inwards towards the fixed frame 211 after completing the initial buffer. At this time, several hinge blocks 223 installed on the side of the anti-collision plate 214 near the fixed frame 211 will move synchronously with the anti-collision plate 214. Since hinge blocks 223 are rotatably connected to hinge block 222 inside the fixed frame 211 via hinge rod 224, the movement of hinge block 223 will push the hinge rod 224 to rotate around the hinge point, thereby causing the sliding block 221 fixedly connected to hinge block 222 to move along the inclined sliding rod 217 installed inside the fixed frame 211. When the sliding block 221 slides along the sliding rod 217, it compresses the spring 218 wrapped around the outer surface of the sliding rod 217, causing the spring 218 to undergo elastic deformation. Since the sliding rods 217 are set in pairs and installed inside the two fixed frames 211 respectively, the sliding direction of the sliding block 221 forms a certain angle with the direction of the impact force, which can disperse the remaining impact force to different directions of the fixed frame 211, avoiding the impact force from being concentrated in a single area of ​​the fixed frame 211. At the same time, the elastic deformation process of the spring 218 can continuously absorb the impact energy, converting the impact kinetic energy into elastic potential energy and storing it. After the impact force disappears, the spring 218 can push the sliding block 221, the hinge rod 224 and the hinge block 223 back to the initial position by resetting. The anti-collision plate 214 is reset, realizing the second level of energy absorption and structural reset function. At the same time, the inclined protective rods 225 on both sides of the transformer 111 provide lateral support for the fixed frame 211 to prevent the fixed frame 211 from tipping over. During the movement of the anti-collision plate 214 toward the fixed frame 211, the push plate 311 on the anti-collision plate 214 pushes the airbag 314 into the frame 312 and the slot 313 to compress the airbag 314. After the airbag 314 is inflated, it forms support on the inside of the fixed frame 211 to prevent the fixed frame 211 from being deformed by impact and to prevent the deformation from causing secondary damage to the transformer 111, thus achieving comprehensive anti-collision protection for the power station transformer.
