Description

Technical Field

[0001] This invention relates to the field of fencing technology, and more specifically to a collision protection fence for power facilities. Background Technology

[0002] Generally speaking, crash protection fences are devices used for the protection, isolation, and collision prevention of power facilities. During the operation and protection of power facilities, they need to block and buffer accidental impacts from external vehicles, equipment, and personnel, prevent impact forces from acting directly on the power facilities themselves, prevent damage to power equipment, power outages, and safety accidents, and at the same time ensure the safe and stable operation of personnel and equipment around the power facilities.

[0003] Collision buffering and structural stability are crucial aspects, directly impacting the operational safety of power facilities and the personal safety of surrounding personnel. While existing collision protection fences generally incorporate buffer devices to mitigate impact damage, these structures cannot completely offset the impact energy under significant external force. This can lead to the railings detaching from the fence body, or even flying debris. These flying fragments can directly impact power facilities, causing equipment deformation, line damage, power outages, and even electric shock risks. More seriously, high-speed flying fence debris can cause severe personal injury to on-site construction workers, pedestrians, and vehicles, posing a significant safety hazard. Furthermore, once the railings and frame break or detach, the entire structure becomes completely ineffective, making quick partial disassembly and replacement impossible. Complete removal and repair or replacement is necessary, resulting in high maintenance costs, long maintenance times, and the loss of protection for power facilities during maintenance, further increasing safety risks. Therefore, this invention aims to provide a collision protection fence for power facilities that reduces the risk of impact debris, improves protective safety, and facilitates partial disassembly and maintenance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a collision protection fence for power facilities, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: A collision protection fence for power facilities includes: A base is fixedly installed on the ground in front of the power facility. A groove is provided on the top of the base, and two symmetrically arranged sliding blocks are slidably installed within the groove. Each sliding block has a column on its top. Each sliding block is connected to the base via a tension spring. The preload of the two tension springs brings the two sliding blocks closer together. A separation assembly is provided inside the base and is connected to the two sliding blocks. An inclined side is provided on the opposite face of each of the two columns, and a wheel groove is provided on the inclined side. The inclined side is arranged at an angle, and the distance between the two inclined sides decreases along the direction from the base towards the power facility. Two symmetrically arranged vertical rods are provided between the two columns, and a connecting assembly is provided on each vertical rod. The two vertical rods are connected by the connecting assembly to multiple equally spaced horizontal rods. Rollers are rotatably installed on the vertical rods, and the rollers are rolled within wheel grooves. The connecting rods are rotatably mounted on the top of the vertical rod. The connecting rods have a waist-shaped groove. The top of the column is provided with a second screw, which is located in the waist-shaped groove and is slidably connected to the waist-shaped groove.

[0006] As a further aspect of the present invention: the column and the slide are rotatably connected, and each slide is rotatably mounted with a rotating shaft on its top. The rotating shaft is coaxially and fixedly connected to the column. Two symmetrically arranged locking blocks are fixedly mounted on the base. Each column is fixedly mounted with a U-shaped rod. One end of the U-shaped rod is slidably mounted in the locking block. When the crossbar is impacted and moves toward the power facility, the roller and the wheel groove roll together to make the column move. At this time, the two columns move away from each other, and the U-shaped rod moves out of the locking block. At the same time, the roller and the wheel groove separate, causing the column to rotate and the column to abut against the locking block. At this time, the preload of the two tension springs makes the two slides move closer together.

[0007] As a further embodiment of the present invention: a screw hole is provided at the top of the column, the screw hole is coaxially arranged with the slide block, and the bottom end of the second screw is threadedly connected to the screw hole.

[0008] As a further embodiment of the present invention: the connecting component includes a U-shaped block, a first screw, and a through hole. Multiple U-shaped blocks are fixedly installed on the vertical rod and are arranged at equal intervals. The through hole is opened at both ends of the horizontal rod. The first screw passes through the U-shaped block and is threadedly connected to the U-shaped block. The end of the horizontal rod is slidably connected to the groove of the U-shaped block. The first screw is slidably inserted into the through hole.

[0009] As a further aspect of the present invention: the separation component includes an inner groove, sliding blocks, and a driving component. The inner groove is formed within a sliding groove, and two symmetrically arranged sliding blocks are slidably installed within the inner groove. One end of each sliding block extends into the sliding groove. The two sliding blocks are driven by the driving component to move towards each other. When the driving component drives the two sliding blocks to move away from each other, the two sliding blocks abut against two sliding seats, causing the sliding seats to move against the preload of the tension spring.

[0010] As a further aspect of the present invention: the driving assembly includes a bidirectional lead screw and a servo motor. The bidirectional lead screw is rotatably installed in the inner groove, and both ends of the bidirectional lead screw are threadedly connected to two sliding blocks respectively. The bidirectional lead screw is driven to rotate by a servo motor fixedly installed on the base.

[0011] As a further aspect of the present invention, a buffer pad is fixedly installed on the side of the column away from the power facility.

[0012] As a further aspect of the present invention, a reflective strip is fixedly installed on the side of the crossbar away from the power facility.

[0013] The beneficial effects of this invention are: 1. In this invention, the waist-shaped groove on the connecting rod slides into the second screw at the top of the column. When the horizontal bar is severely impacted and the roller disengages from the groove, the waist-shaped groove and the second screw form a rigid limit, preventing the vertical bar and horizontal bar from continuing to move and splash. At the same time, the tension spring pulls the column to close in opposite directions to clamp the impacting object, forming double protection. This avoids the problems of traditional fences splashing after impact and the impacting object continuing to approach the power facilities. It eliminates the safety hazards of the splashing fence to the power facilities and surrounding personnel from the root and prevents the impact accident from further escalating. 2. In this invention, the column and the slide are rotatably connected, and the U-shaped rod and the locking block are used for limiting. In the event of a severe impact, the U-shaped rod moves out of the locking block, the column rotates around the axis and is positioned by the locking block. Its flat side replaces the beveled tip to clamp the impacting object. At the same time, the buffer pad on the column provides flexible cushioning, avoiding the problem of secondary damage to the impacting object during clamping, thus improving the safety of protection. In addition, the contact area between the rotated column and the object is larger, and the clamping is more stable, further ensuring the safety of power facilities. 3. In this invention, the U-shaped block of the connecting component, the first screw and the through hole cooperate to realize the quick assembly and disassembly of a single horizontal bar and vertical bar. Combined with the threaded connection of the second screw and the screw hole, the assembly and disassembly of the entire railing and the post can be completed quickly. It can meet the replacement needs of partially damaged parts, avoid the problems of traditional fence railing assembly and disassembly and high maintenance costs. At the same time, other protective structures can still play a role during maintenance, preventing power facilities from losing protection, simplifying the maintenance process and reducing maintenance costs.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 As shown, the present invention is a collision protection fence applied to power facilities, comprising: A base 1 is fixedly installed on the ground in front of the power facility. The top of the base 1 has a groove 9, in which two symmetrically arranged slide blocks 10 are slidably installed. Each slide block 10 has a column 2 on its top. Each slide block 10 is connected to the base 1 by a tension spring 12. The preload of the two tension springs 12 brings the two slide blocks 10 closer together. A separation component is provided inside the base 1 and is connected to the two slide blocks 10. The opposite faces of the two columns 2 have inclined sides 3, and wheel grooves 4 are provided on the inclined sides 3. The inclined sides 3 are arranged at an angle, and the distance between the two inclined sides 3 decreases along the direction from the base 1 toward the power facility. Two symmetrically arranged vertical rods 5 are arranged between the two columns 2. Each vertical rod 5 has a connecting component 8. The two vertical rods 5 are connected by the connecting component 8 to multiple equally spaced horizontal rods 7. Rollers 6 are rotatably installed on the vertical rods 5 and are rolled in the wheel grooves 4. Two connecting rods 15 are rotatably mounted on the top of the vertical rod 5. The connecting rod 15 has a waist-shaped groove 16. The top of the column 2 is provided with a second screw 17, which is located in the waist-shaped groove 16 and is slidably connected to the waist-shaped groove 16.

[0019] The working principle of this invention is as follows: First, multiple horizontal bars 7 are connected by vertical rods 5 and connecting components 8 to form a railing assembly. After the base 1 is fixed to the ground, the separation component pushes the slide block 10 to overcome the pre-tightening force of the tension spring 12, causing the two uprights 2 to separate. The railing assembly is then placed between the two uprights 2, ensuring that the rollers 6 on the vertical rod 5 are installed in the wheel grooves 4 of the uprights 2, and that the waist-shaped groove 16 of the connecting rod 15 is slidably connected to the second screw 17. Finally, the pushing of the separation component is canceled, and under the pre-tightening force of the tension spring 12, the slide block 10 drives the uprights 2 to move closer together, completing the assembly. Normal protection status: such as Figure 1 As shown in the example, the base 1 is fixed to the ground, the tension spring 12 is in the normal contracted state, the two slides 10 are pulled closer to each other, the slides 10 drive the column 2 to tighten, the roller 6 on the vertical rod 5 rolls in the wheel groove 4 of the inclined side 3 to keep the horizontal bar 7 in a stable position away from the power facilities, forming a protective barrier. Minor impact condition: such as Figure 6As shown in the example, when an external object slightly impacts the horizontal bar 7, the impact force is transmitted to the horizontal bar 7, pushing the horizontal bar 7 and the vertical bar 5 together to move towards the power facility. When the vertical bar 5 moves, it drives the rollers 6 on both sides to roll upward along the grooves 4 of the inclined sides 3 of the column 2. Since the distance between the two inclined sides 3 decreases in the direction towards the power facility, the rollers 6 will generate a lateral thrust on the inclined sides 3 during the rolling process, forcing the two columns 2 to move away from each other. The columns 2 drive the slide block 10 to slide to both sides along the slide groove 9. The slide block 10 stretches the tension spring 12, and the tension spring 12 undergoes elastic deformation, converting the impact energy into elastic potential energy, realizing primary buffering, reducing the transmission of impact force to the power facility, and solving the problems of poor buffering effect and easy damage to the power facility by impact force in existing fences. When the impact force is removed, the vertical rod 5 moves toward the power facility, causing the connecting rod 15 at the top to rotate around the rotation point at the top of the vertical rod 5. The second screw 17 at the top of the column 2 slides relative to the waist groove 16 of the connecting rod 15, providing a margin of movement for the vertical rod 5 to avoid the vertical rod 5 and the column 2 getting stuck, ensuring a smooth buffering process. When the impact force is removed, the tension spring 12 contracts under the action of elastic restoring force, pulling the slide 10 and the column 2 back to the center. The slide 10 drives the column 2 to move closer, the roller 6 falls back along the wheel groove 4, the vertical rod 5 and the horizontal rod 7 return to the initial protective position, the connecting rod 15 returns to the center with the vertical rod 5, the second screw 17 returns to the center of the waist groove 16, and the fence returns to the normal protective state without manual intervention. Severe impact condition: When the impact force exceeds the buffer limit of the tension spring 12, the roller 6 will disengage from the wheel groove 4. At this time, the vertical bar 5 and the horizontal bar 7 lose the lateral restraint of the column 2, and there is a risk of flying outwards. As the vertical bar 5 continues to move towards the power facility, the connecting rod 15 moves synchronously until the second screw 17 moves to the end of the waist groove 16. The waist groove 16 and the second screw 17 form a rigid restraint, preventing the vertical bar 5 and the horizontal bar 7 from continuing to move and fly out, avoiding the high-speed flying of railing fragments that may hit the power facility or surrounding personnel, thus solving the major safety hazard of railing fragments flying out after an impact from the root. At the same time, after the roller 6 disengages from the groove 4, the column 2 loses its lateral constraint. The tension spring 12 quickly pulls the two columns 2 together to clamp the impacting object, restricting it from continuing to approach the power facility, thus achieving secondary protection and preventing the impact accident from escalating further.

[0020] like Figures 1-7As shown in the preferred embodiment of the present invention, the column 2 is rotatably connected to the slide 10, and a rotating shaft 11 is rotatably mounted on the top of each slide 10. The rotating shaft 11 is coaxially fixedly connected to the column 2. Two symmetrically arranged locking blocks 14 are fixedly mounted on the base 1. A U-shaped rod 13 is fixedly mounted on each column 2. One end of the U-shaped rod 13 is slidably mounted in the locking block 14. When the crossbar 7 is impacted and moves toward the power facility, the roller 6 and the wheel groove 4 roll together to make the column 2 move. At this time, the two columns 2 move away from each other, and the U-shaped rod 13 moves out of the locking block 14. At the same time, the roller 6 separates from the wheel groove 4, causing the column 2 to rotate, and the column 2 abuts against the locking block 14. At this time, the preload of the two tension springs 12 makes the two slides 10 move closer.

[0021] In practical application, under normal conditions, the U-shaped rod 13 is slidably installed within the locking block 14. The locking block 14 limits the movement of the U-shaped rod 13, restricting the rotation of the column 2 around the pivot 11, ensuring the column 2 remains vertical, and allowing the roller 6 to stably engage with the wheel groove 4, thus guaranteeing the overall installation stability of the railing. Figure 7 As shown in the example, when the impact force causes the roller 6 to roll along the groove 4 and the posts 2 to move away from each other, the U-shaped rod 13 moves synchronously with the posts 2 and gradually moves out of the locking block 14. When the roller 6 completely leaves the groove 4, the U-shaped rod 13 completely leaves the locking block 14, releasing the rotation restriction on the posts 2. At this time, the lateral thrust of the roller 6 on the inclined side 3 after leaving the groove 4 will drive the posts 2 to rotate around the pivot 11 until the side of the posts 2 abuts against the locking block 14. The locking block 14 plays a positioning role for the posts 2, preventing the posts 2 from rotating excessively. After the posts 2 rotate, their flat side replaces the tip of the inclined side 3. When the tension spring 12 pulls the posts 2 to clamp the impacting object, it avoids the tip causing secondary damage to the impacting object, solving the problem of secondary damage that is easy to occur when the existing fence clamps. At the same time, the contact area between the rotated posts 2 and the object is larger, the clamping is more stable, further restricts the movement of the object, and improves the reliability of protection.

[0022] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the top of the column 2 is provided with a screw hole 18, the screw hole 18 is coaxially arranged with the slide 10, and the bottom end of the second screw 17 is threadedly connected to the screw hole 18.

[0023] In practical application, when assembling the railing assembly with the post 2, first adjust the rotation angle of the connecting rod 15 at the top of the vertical rod 5 so that the slot 16 on the connecting rod 15 aligns with the screw hole 18 at the top of the post 2. Pass the second screw 17 through the slot 16, and then thread the bottom end of the second screw 17 into the screw hole 18. Tighten the second screw 17 clockwise to complete the fixed connection between the connecting rod 15 and the post 2. The operation is simple and convenient, requiring no complicated tools. When the railing assembly is damaged and needs to be disassembled for repair or replacement, unscrew the second screw 17 counterclockwise to release the second screw 17 from the slot 16, thereby releasing the constraint of the post 2 on the vertical rod 5 and the horizontal rod 7. The railing assembly can then be removed from between the two posts 2 for subsequent repair or replacement.

[0024] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the connecting component 8 includes a U-shaped block 801, a first screw 802, and a through hole 803. Multiple U-shaped blocks 801 are fixedly installed on the vertical rod 5, and are arranged at equal intervals. The through hole 803 is opened at both ends of the horizontal rod 7. The first screw 802 passes through the U-shaped block 801 and is threadedly connected to the U-shaped block 801. The end of the horizontal rod 7 is slidably connected to the groove of the U-shaped block 801, and the first screw 802 is slidably inserted into the through hole 803.

[0025] In practical application, when assembling the railing as a whole, align the two ends of the horizontal bar 7 with the corresponding U-shaped block 801 grooves on the two vertical bars 5, insert the ends of the horizontal bar 7 into the grooves, ensuring that the through holes 803 at both ends of the horizontal bar 7 are aligned with the holes on the U-shaped block 801. Then, insert the first screw 802 through one side of the U-shaped block 801 into the through hole 803, and then thread the first screw 802 to the U-shaped block 801. Tighten the first screw 802 to complete the fixing of a single horizontal bar 7 to the vertical bar 5. Multiple horizontal bars 7 are installed sequentially according to the above steps. It can be assembled into a complete railing, and the assembly process is simple and can be completed quickly. When a horizontal bar 7 is damaged by an impact, it is not necessary to disassemble the entire railing. Simply unscrew the first screws 802 at both ends of the horizontal bar 7, and the damaged horizontal bar 7 can be taken out from the groove of the U-shaped block 801. After replacing the new horizontal bar 7, tighten the first screws 802 to complete the repair. This achieves quick partial replacement, solves the problem of high cost of disassembly and maintenance of existing railings, and ensures that other horizontal bars 7 can still play a protective role during the repair, preventing the power facilities from losing protection.

[0026] like Figures 1-2As shown, in a preferred embodiment of the present invention, the separation component includes an inner groove 20, sliding blocks 21, and a drive component. The inner groove 20 is opened in the slide groove 9. Two symmetrically arranged sliding blocks 21 are slidably installed in the inner groove 20. One end of each sliding block 21 extends into the slide groove 9. The two sliding blocks 21 are driven by the drive component to move towards each other. When the drive component drives the two sliding blocks 21 to move away from each other, the two sliding blocks 21 respectively abut against the two slide seats 10, so that the slide seats 10 move against the preload of the tension spring 12.

[0027] Specifically, the drive assembly includes a bidirectional lead screw 22 and a servo motor 23. The bidirectional lead screw 22 is rotatably installed in the inner groove 20, and both ends of the bidirectional lead screw 22 are threadedly connected to two sliding blocks 21 respectively. The bidirectional lead screw 22 is driven to rotate by the servo motor 23 fixedly installed on the base 1.

[0028] In practical application, under normal conditions, the servo motor 23 is off, the bidirectional lead screw 22 remains stationary, and the two sliding blocks 21 are close to each other and located in the middle of the inner groove 20, not in contact with the slide block 10, thus not affecting the contraction action of the tension spring 12 on the slide block 10, ensuring the stability of the fence under normal protection. When it is necessary to assemble the entire fence, the servo motor 23 is started, and the output shaft of the servo motor 23 drives the bidirectional lead screw 22 to rotate clockwise. Since the threads at both ends of the bidirectional lead screw 22 rotate in opposite directions, the two sliding blocks 21 will move away from each other along the inner groove 20, and the sliding blocks 21 extend into the groove 9. The end gradually abuts against the slide block 10 and continuously pushes the slide block 10 to slide along the slide groove 9 to both sides. The slide block 10 stretches the tension spring 12, causing the two posts 2 to move away from each other until a suitable distance is reached for the installation of the entire railing. The servo motor 23 is turned off, and the sliding block 21 maintains its current position, fixing the open state of the posts 2, which facilitates the overall installation of the railing and solves the problem of the posts 2 being difficult to fix and the assembly being cumbersome when assembling existing fences. When an impact accident occurs and it is necessary to release the clamping of the posts 2 on the impacting object, the two posts 2 can also be separated by pushing the slide block 10 to release the clamping and facilitate the cleaning of the impacting object.

[0029] like Figures 1-7 As shown, in a preferred embodiment of the present invention, a buffer pad 19 is fixedly installed on the side of the column 2 away from the power facility.

[0030] In practical application, under normal conditions, the buffer pad 19 covers the side of the post 2 away from the power facilities, which can provide initial buffering for minor collisions, reduce damage to the post 2 body, and extend the service life of the post 2. When the post 2 rotates and clamps the impacting object, the buffer pad 19 comes into contact with the object again, further buffering and shock absorption, avoiding damage to the object or wear of the post 2 caused by rigid friction between the post 2 and the object, while improving the stability of clamping and preventing the object from sliding, thus solving the problem that the existing fence post 2 is too rigid and easily causes secondary damage.

[0031] like Figure 1 As shown, in a preferred embodiment of the present invention, a reflective strip 24 is fixedly installed on the side of the crossbar 7 away from the power facility.

[0032] In practical applications, the reflective strips 24 on the crossbar 7 reflect light in low-light conditions, reminding passing vehicles and pedestrians to pay attention and avoid the area, reducing the probability of accidental collisions, and solving the problem of poor warning effect and easy accidental collisions of existing fences.

[0033] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
