Description

Technical Field

[0001] This utility model belongs to the field of power safety fence technology, and specifically relates to a pre-embedded power safety fence with warning function. Background Technology

[0002] In the field of power construction, the proper use of safety protection equipment plays a key role in ensuring personnel safety and reducing accident risks. As an important component, safety fences mainly function to clearly define and restrict the range of personnel movement within a specific area of ​​the power site, thereby effectively eliminating or mitigating potential safety hazards. Given the diverse needs of different power construction scenarios, safety fences have evolved into various types, such as netting, fencing, and warning tape. Among them, warning tape safety fences are widely used in various power operation environments due to their eye-catching warning effect.

[0003] However, the common power safety fences currently in use have revealed many problems in actual use. Most safety fences adopt a fixed structure design, which makes it extremely inconvenient to disassemble and move them after the construction site changes or the work is completed. This seriously affects work efficiency and equipment reusability. More importantly, many safety fences have simple structures, limited height, and lack effective blocking and prevention measures, which can be easily climbed over by personnel. This greatly weakens the protective effectiveness of the safety fences and leads to high safety risks at the construction site.

[0004] To address these issues, Chinese Patent No. CN219100927U discloses a warning-oriented pre-embedded power safety fence. This fence, by incorporating a pre-embedded base, a base, a pole, a disassembly mechanism, and a fence mechanism, to some extent solves the problems of inconvenient disassembly and easy climbing of existing fixed safety fence structures. However, in practical applications, this device still has significant limitations. Firstly, it uses a screw-assisted installation method. When disassembly or assembly is required, because the pre-embedded base is deeply buried in the soil, it can only be disassembled by turning the bolts. However, in harsh outdoor environments, the bolts are prone to corrosion. Even if no corrosion occurs, soil and sand can easily enter the thread gaps, causing the threads to jam and making it difficult to turn the bolts, greatly increasing the difficulty and complexity of disassembly and assembly. Secondly, this safety fence lacks height adjustment functionality, failing to flexibly adjust its height according to the specific needs of different construction scenarios, resulting in poor adaptability in various complex environments and making it difficult to fully exert its safety protection function. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a pre-embedded power safety fence with warning features, so as to solve the problems of difficulty in quick disassembly and maintenance and lack of height adjustment function during the application of the existing technology.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A warning-oriented pre-embedded power safety fence includes a base plate, with buried frames fixedly installed on both sides of the bottom of the base plate, an installation mechanism fixedly installed on the top of the base plate, a base plate installed on the top of the base plate through the installation mechanism, a lifting fence fixedly installed on the top of the base plate, and a warning mechanism fixedly installed on the top of the lifting fence.

The top of the telescopic frame is connected to a warning mechanism, and an adjusting handle is rotatably connected to the bottom of the rail frame. The top of the adjusting handle is connected to the bottom of the lead screw.

[0011] As a preferred technical solution, a fixing screw is threadedly connected to one side of the adjusting handle, and the end of the fixing screw passes through the adjusting handle. The fixing screw is a hand-tightening screw.

[0012] As a preferred technical solution, the bottom of the rail frame has limit holes arranged in a ring at equal intervals, and the top of the fixing screw is inserted into the limit hole.

[0013] As a preferred technical solution, the warning mechanism includes a top plate, which is fixedly installed on the top of the telescopic frame. An LED warning sign is fixedly installed on the front of the top plate. A battery is installed in the middle of the rear side of the LED warning sign's housing.

This design greatly improves the ease of use of the device.

[0017] Secondly, this device improves adaptability by setting up a lifting fence. When adjusting, turning the adjustment handle drives the lead screw to make the sliding block slide on the rail frame, thereby enabling the telescopic frame and other components to adjust the height. After adjustment, the fixing screw is inserted into the limit hole to lock it in place. In addition, the warning mechanism is powered by a photovoltaic panel, and the LED light sign illuminates at night. The protective spikes prevent people from climbing over, thus improving the overall protective performance. Attached Figure Description

[0025] Example

[0026] refer to Figures 1 to 6 This embodiment of a pre-embedded power safety fence with warning features includes a base plate 1, with buried frames 2 fixedly installed on both sides of the bottom of the base plate 1, an installation mechanism 3 fixedly installed on the top of the base plate 1, a base plate 4 installed on the top of the base plate 1 through the installation mechanism 3, a lifting fence 5 fixedly installed on the top of the base plate 4, and a warning mechanism 6 fixedly installed on the top of the lifting fence 5.

[0027] The mounting mechanism 3 includes a frame 31, a limiting component 32, and an insert block 33. The frame 31 is fixedly installed on the top two sides of the base plate 1, and the insert block 33 is fixedly installed on the bottom two sides of the base plate 4. The insert block 33 is inserted into the inside of the frame 31. The limiting component 32 is fixedly installed in the middle of the top of the base plate 1, and the outer end of the limiting component 32 passes through the frame 31 and the insert block 33 to engage. During use, the entire fence can be securely buried underground by the underground frame 2 fixedly installed on the bottom two sides of the base plate 1 to ensure its foundation stability. When it is necessary to install the base plate 4 and the upper structure, the insert blocks 33 fixed on the bottom two sides of the base plate 4 are inserted into the frame 33 on the top two sides of the base plate 1. Inside 1, the insert 33 on the insert block 33 also enters the frame 31. Then, the limiting component 32 located in the middle of the top of the base plate 1 is operated. The outer end of the limiting component 32 moves, passes through the frame 31 and engages with the insert 33, thereby firmly fixing the base plate 4 to the base plate 1. On this basis, the lifting fence 5 and the warning mechanism 6 fixed on the top of the base plate 4 can function normally. The lifting fence 5 provides protection, and the warning mechanism 6 serves as a warning in electrical locations. When it is necessary to remove, the limiting component 32 is operated in reverse so that its outer end separates from the insert 33, and the base plate 4 can be removed from the base plate 1 to complete the disassembly of the relevant components.

[0028] refer to Figures 1-4 and Figure 6The limiting component 32 includes a frame 321 and a slot 322. The frame 321 is fixedly installed in the middle of the top of the base plate 1. Limiting springs 323 are fixedly connected to both sides of the inside of the frame 321. A movable block 324 is fixedly connected to the outer end of the limiting spring 323. A limiting frame 325 is fixedly installed on the outer side of the movable block 324. The slot 322 is opened in the inner side of the insert block 33. A limiting block 326 is fixedly installed on the outer end of the limiting frame 325. The outer end of the limiting block 326 passes through the frame 31 and is inserted into the inside of the slot 322. The lifting fence 5 includes a rail frame 51. The rail frame 51 is fixedly installed on both sides of the bottom of the base plate 4. A lead screw 52 is rotatably connected inside the rail frame 51. A sliding block 53 is threadedly connected to the outer surface of the lead screw 52. A telescopic frame 54 is fixedly installed on the outer side of the sliding block 53. The top of the telescopic frame 54 is connected to the warning mechanism 6. An adjusting handle 55 is rotatably connected to the bottom of the rail frame 51. The top of the adjusting handle 55 is connected to the lead screw 52. The bottom of the rod 52 is connected. During installation, the movable blocks 324 on both sides of the frame 321 are pushed to compress the limiting spring 323, which causes the limiting frame 325 and the outer limiting block 326 to retract inward. The bottom insert block 33 of the base plate 4 and the insert block 33 are inserted into the card frame 31 on the base plate 1. The movable block 324 is released, the limiting spring 323 rebounds, and the movable block 324 and the limiting frame 325 are pushed outward, so that the limiting block 326 passes through the card frame 31 and is inserted into the card slot 322 on the inner side of the insert block 33, thus realizing a stable connection between the base plate 4 and the base plate 1. When adjusting the height of the lifting fence 5, the bottom adjustment handle 55 of the rail frame 51 is rotated to drive the lead screw 52 to rotate. The lead screw 52 drives the sliding block 53 connected to the thread on the outer surface to slide in the rail frame 51. The telescopic frame 54 on the outer side of the sliding block 53 moves accordingly. Since the top of the telescopic frame 54 is connected to the warning mechanism 6, the warning mechanism 6 and the entire lifting fence 5 can be adjusted in height to adapt to different scene requirements.

[0029] refer to Figures 1-4A fixing screw 56 is threadedly connected to one side of the adjusting handle 55. The end of the fixing screw 56 passes through the adjusting handle 55. The fixing screw 56 is a hand-tightening screw. Limiting holes 57 are evenly spaced and arranged in a ring at the bottom of the rail frame 51. The top of the fixing screw 56 is inserted into the limiting hole 57. When adjusting the height of the lifting fence 5 during use, the adjusting handle 55 is rotated, which drives the lead screw 52 to operate, thereby raising and lowering the lifting fence 5. When the appropriate height is reached, the hand-tightening fixing screw 56 is threadedly connected to one side of the adjusting handle 55, and the end of the fixing screw 56 passes through the adjusting handle 55. The bottom of the rail frame 51 has limit holes 57 arranged in a ring at equal intervals. At this time, by manually rotating the fixing screw 56, its top is inserted into the limit hole 57 of the corresponding height. The fixing screw 56 and the limit hole 57 cooperate with each other to restrict the rotation of the adjusting handle 55, thereby fixing the position of the lead screw 52. This prevents the movable block 324 from sliding freely in the rail frame 51, ensuring that the telescopic frame 54 and the entire lifting fence 5 remain stable at the adjusted height. This prevents the fence height from changing due to accidental contact with the adjusting handle 55, ensuring the safety and stability of the power safety fence during use.

[0030] refer to Figures 1-3The warning mechanism 6 includes a top plate 61, which is fixedly installed on the top of the telescopic frame 54. An LED warning light sign 62 is fixedly installed on the front of the top plate 61. A battery is installed in the middle of the rear side of the housing of the LED warning light sign 62. Photovoltaic panels 63 are fixedly installed on both sides of the top of the top plate 61. Support rods 64 are fixedly installed on both sides of the bottom of the top plate 61 in a linear arrangement with equal spacing. Sliding sleeves 65 are slidably connected to the outer surface of the support rods 64. The bottom of the sliding sleeves 65 is connected to the top of the base plate 4. Protective tips are fixedly connected to the top of the top plate 61 in a linear arrangement with equal spacing. When the warning mechanism 6 of this device is working, the top plate 61 serves as a carrier, fixedly installed on top of the telescopic frame 54. Its height adjusts with the raising and lowering of the telescopic frame 54. In daily use, the photovoltaic panels 63 on both sides of the top of the top plate 61 collect solar energy, converting it into electrical energy and storing it in the battery installed in the middle of the rear side inside the LED warning sign housing. This provides power to the warning sign. When entering nighttime or low-light environments, the battery powers the LED warning sign, causing it to illuminate and emit a conspicuous warning signal to the surrounding environment, alerting personnel. In the power safety area, the top plate 61 has linearly arranged support rods 64 at equal intervals on both sides of its bottom, and a sliding sleeve 65 is fitted on its outer surface to ensure the stability of the lifting and lowering action of the top plate 61 as it rises and falls with the telescopic frame 54. In addition, the protective spikes 66 at equal intervals on the top of the top plate 61 can effectively prevent people from climbing over the fence, further enhancing the safety protection effect and ensuring the safety of the power site in all aspects. An infrared proximity sensor 67 is fixedly connected to one side of the front of the LED warning light sign 62, and an audible and visual buzzer 68 is fixedly connected to the other side of the front of the LED warning light sign. The LED warning light sign 62 has a control module inside. By setting the infrared proximity sensor 67, the device can detect the area around the safety fence during use. When someone approaches the safety fence, the infrared proximity sensor 67 can assist in detection and feed the information back to the control module. At this time, the control module can activate the audible and visual buzzer 68 to sound an alarm, which can further improve the warning effect and also play a certain role in repelling birds, further improving the warning performance of the device during use.

[0031] Operating Principle and Advantages: This device, through the installation mechanism 3, effectively improves the efficiency of installation and disassembly. During the installation of the lifting fence 5, the inserts 33 on both sides of the bottom of the lifting fence 5 are precisely inserted into the frame 31. During this process, by adjusting the mechanism, the two movable blocks 324 are pushed inwards. The movement of the movable blocks 324 exerts pressure on the limiting spring 323. Simultaneously, the limiting frame 325 is pulled out, causing the limiting block 326 to move inwards. After the inserts 33 are inserted into the frame 31, the lifting fence 5 can be installed on the top of the base plate 4. After installation, the movable blocks 324 are released. As the limiting spring 323 returns to its original position, it pushes the movable blocks 324 outwards. The outward movement of the movable blocks 324 further pushes the limiting frame 326. 25 moves outward, thereby causing the limiting frame 325 to push the limiting block 326 into the slot 322. When the limiting block 326 and the slot 322 are mutually engaged and limited, the installation and fixation of the lifting fence 5 and the warning mechanism 6 on the top of the device are quickly completed. When the lifting fence 5 needs to be removed, simply push the two movable blocks 324 inward to pull the limiting frame 325 and the limiting block 326 at its end out of the slot 322. After the limiting block 326 is separated from the slot 322, the limiting relationship between the insert block 33 and the frame 31 is released. At this time, the lifting fence 5 can be easily removed from the top of the base plate 4. This design of the installation mechanism 3 enables the device to quickly realize the installation and disassembly of the lifting fence 5, greatly improving the convenience of the device.

[0032] This device, through its lifting fence 5, effectively enhances its adaptability in different scenarios. When adjusting the protective height of the lifting fence 5, the adjustment handle 55 is rotated. The rotation of the adjustment handle 55 drives the lead screw 52 to rotate, causing the sliding block 53 to slide inside the rail frame 51. The sliding of the sliding block 53 inside the rail frame 51 drives the telescopic frame 54 to slide up and down. The up and down sliding of the telescopic frame 54, in turn, assists in moving the top plate 61 up and down. During the up and down movement of the top plate 61, the support rod 64 and the sliding sleeve 65 slide up and down synchronously, thereby realizing the lifting fence. The height of the barrier 5 is extended. After the height adjustment is completed, simply twist the fixing screw 56 upwards to insert it into the matching limiting hole 57. Once the fixing screw 56 and the limiting hole 57 are mutually inserted and limited, the lifting barrier 5 can be quickly locked and fixed. In addition, this device is also equipped with a warning mechanism 6. During use, the photovoltaic panel 63 can convert light energy into electrical energy and supply it to the battery. At night, the LED warning light can be activated to provide a good warning effect. At the same time, the protective spikes 66 on the device can effectively prevent people from climbing over the lifting barrier 5, significantly improving the overall protective performance of the device.
