Technical Field
[0001] This utility model relates to the field of power construction safety protection technology, and in particular to a power facility safety protection device for power construction sites. Background Technology
[0002] Electricity is an energy source that uses electrical energy as its power source. It is a power production and consumption system composed of power generation, transmission, transformation, distribution, and consumption. It converts primary energy from nature into electricity through power generation devices, and then supplies the electricity to various users through transmission, transformation, and distribution. The safety protection devices for power facilities used at construction sites are generally modular. The modular protective devices can provide safety protection for the power construction site.
[0003] Although it enables multi-angle splicing of protective devices, it has limitations, including complex structure, numerous parts, high production costs, and difficulty in later maintenance, which increases the cost of later maintenance.
[0004] An existing patent (publication number: CN222362820U) discloses a safety protection device for power facilities at construction sites. This utility model can be installed by simply plugging the mounting block and the mounting base together, and then using a spring to push the limiting plate to limit the mounting block. This allows for multi-angle splicing installation, has a simple and easy-to-operate structure, fewer parts, and is easier to produce. It is energy-saving and environmentally friendly, and has higher installation efficiency.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, the power construction safety protection devices proposed in these patents have some practical application problems from an operational perspective. Although the extension frame can slide and extend within the protective frame, it lacks a locking structure. This makes the extension frame prone to sliding due to shaking during transport, which may not only damage itself and other components but also increase the difficulty and cost of transport. During use, the extended frame cannot be effectively fixed and is prone to movement or retraction, resulting in unstable extension length of the protective device. This makes it impossible to provide a stable protection range for the construction site and seriously affects the safety protection performance.
[0006] Therefore, a safety protection device for power facilities at power construction sites is proposed. Utility Model Content

[0027] 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 protection scope of the present utility model.
[0028] Please see Figure 1-6 The present invention provides the following technical solution:
[0029] A safety protection device for power facilities at a power construction site includes a protective mesh frame 1, with bases 2 fixedly connected to the front and rear sides of the top of the protective mesh frame 1, an extension mesh plate 3 inside the protective mesh frame 1, a positioning component 4 between the extension mesh plate 3 and the protective mesh frame 1, and an extension connection component 5 on the outer side of the protective mesh frame 1 and the extension mesh plate 3.
[0030] The positioning component 4 includes a T-slot 41 inside the rear side of the protective mesh frame 1. T-blocks 42 are fixedly connected to the bottom and top of the rear side of the extension mesh plate 3. The T-blocks 42 are slidably connected inside the T-slot 41. An adjustment groove 43 is provided on the top of the front side of the protective mesh frame 1. A sliding screw 44 is fixedly connected to the top of the front side of the extension mesh plate 3. The front side of the sliding screw 44 is slidably connected inside the adjustment groove 43. A hand-tightening nut 45 is threadedly connected to the outer side of the sliding screw 44. The hand-tightening nut 45 is located on the front side of the adjustment groove 43. An auxiliary transfer wheel 46 is bolted to the bottom of the extension mesh plate 3.
[0031] In this embodiment: by setting up a protective mesh frame 1, an extension mesh plate 3, a positioning component 4, and an extension connection component 5, when protection is required at a power construction site, the auxiliary moving wheel 46 of the positioning component 4 can be used to easily push the extension mesh plate 3 to slide within the protective mesh frame 1. At this time, the T-block 42 slides within the T-slot 41, ensuring the smooth movement of the extension mesh plate 3 and preventing deviation. After the extension mesh plate 3 is stretched to a suitable length, the hand-tightening nut 45 on the outside of the sliding screw 44 is rotated to press it against the protective mesh frame 1 within the adjusting groove 43, locking the extension mesh plate 3 and preventing it from slipping during transportation or... If slippage or retraction occurs during use, the extended length of the stabilizing protective device ensures the stability of the protection range at the construction site and improves safety performance. When splicing multiple protective devices, the extension connecting component 5 plays a role, allowing the adjacent extended mesh panel 3 to be directly parallel to the protective mesh frame 1. Compared with the traditional method, there is no need to lift the components, which greatly reduces labor intensity. Construction personnel can complete the splicing work more efficiently, ensuring the standardization of installation. This is conducive to the widespread application of the protective device at the construction site, making the splicing of the protective device more efficient and stable.
[0032] Specifically, such as Figure 5 As shown, the extension connection assembly 5 includes a fixing sleeve 51 fixedly connected to the top and bottom left side of the extension mesh plate 3, and a torsion block 52 is rotatably connected inside the fixing sleeve 51.
[0033] Specifically, such as Figure 5 As shown, a slot 53 is provided on the left side of the twist block 52, and a card block 54 is fixedly connected to the bottom and top of the right side of the protective net frame 1. The size of the card block 54 is slightly smaller than the size inside the slot 53.
[0034] Specifically, such as Figure 5 As shown, a pressure groove 55 is provided on the front side of the card block 54, and a pressing structure 56 is provided inside the front side of the torsion block 52. The rear side of the pressing structure 56 is located on the front side inside the card groove 53.
[0035] In this embodiment: by setting the extension connection component 5, when splicing multiple protective devices, the torsion block 52 in the fixing sleeve 51 on the adjacent extension mesh plate 3 is aligned with the locking block 54 on the protective mesh frame 1. The torsion block 52 is basically in a horizontal state, so that the locking block 54 slides into the locking groove 53 on the left side of the torsion block 52. Then, according to the usage requirements, the rotating pressing structure 56 presses the pressing groove 55 on the front side of the locking block 54 to ensure that the locking block 54 is firmly connected inside its locking groove 53. This design realizes the direct parallel docking of the extension mesh plate 3 and the protective mesh frame 1, abandoning the traditional laborious lifting and installation method, greatly reducing labor intensity, improving construction efficiency, ensuring installation standardization, and making the splicing of protective devices more efficient and stable, which is conducive to the widespread application of the product on the construction site.
[0036] Specifically, such as Figure 6 As shown, the clamping structure 56 includes a threaded post 561 threadedly connected to the front side of the torsion block 52, and a turntable 562 is fixedly connected to the front side of the threaded post 561.
[0037] Specifically, such as Figure 6 As shown, an elastic clamping block 563 is fixedly connected to the rear side of the threaded post 561. The elastic clamping block 563 is located on the front side inside the pressure groove 55, and the size of the elastic clamping block 563 is slightly smaller than the size inside the pressure groove 55.
[0038] In this embodiment: by setting a clamping structure 56, after the locking block 54 slides into the locking groove 53, the turntable 562 on the front side of the rotating threaded column 561 is rotated, causing the threaded column 561 to rotate, so that the elastic clamping block 563 moves into the pressure groove 55. Since the size of the elastic clamping block 563 is slightly smaller than the pressure groove 55, it can fit tightly into the pressure groove 55 during the movement, and use its own elasticity to generate squeezing force to firmly fix the locking block 54 in the locking groove 53. This enhances the stability of the splicing point between the extension mesh plate 3 and the protective mesh frame 1, avoids the splicing part from loosening during use, and ensures the overall safety and reliability of the protective device.
[0039] Specifically, such as Figure 4 As shown, a push-pull handle 6 is bolted to the left side of the extension mesh plate 3, and the left side of the push-pull handle 6 is arc-shaped.
[0040] Specifically, such as Figure 4 As shown, the top and bottom of the front side of the extended mesh plate 3 are provided with hidden grooves 7, and rollers 8 are rotatably connected inside the hidden grooves 7. The outer side of the rollers 8 is in contact with the inside of the protective mesh frame 1.
[0041] In this embodiment: by setting up a push-pull handle 6, a hidden groove 7, and rollers 8, when the extension mesh plate 3 is pulled, the arc-shaped push-pull handle 6 fits the human hand, making it easy to apply force and making the operation more comfortable and effortless. When the extension mesh plate 3 moves, the rollers 8 in the hidden groove 7 roll inside the protective mesh frame 1, changing sliding friction into rolling friction, effectively reducing the friction between the extension mesh plate 3 and the protective mesh frame 1, making the sliding of the extension mesh plate 3 in the protective mesh frame 1 smoother, reducing component wear, extending the service life of the protective device, and further improving the user experience and work efficiency.
[0042] Working principle: When using the power facility protection device at a power construction site, the protection range is first adjusted. The base 2 at the bottom of the protective mesh frame 1 contacts the ground to ensure its overall stability. Then, the construction worker applies force by holding the arc-shaped push-pull handle 6 bolted to the left side of the extension mesh plate 3. At this time, the auxiliary moving wheel 46 at the bottom of the extension mesh plate 3 contacts the ground. In conjunction with the rollers 8 rotatably connected in the hidden grooves 7 at the top and bottom of the front side of the extension mesh plate 3, the sliding friction is converted into rolling friction, which greatly reduces the friction force, allowing the extension mesh plate 3 to slide easily within the protective mesh frame 1. During the sliding process, the T-shaped blocks 42 at the top and bottom of the rear side of the extended mesh plate 3 slide along the T-shaped groove 41 inside the rear side of the protective mesh frame 1, ensuring that the extended mesh plate 3 moves smoothly and does not deviate. When the extended mesh plate 3 is stretched to a suitable length to meet the protection range requirements of the construction site, the construction personnel turn the hand-tightening nut 45 on the outside of the sliding screw 44. The hand-tightening nut 45 gradually presses the protective mesh frame 1 in the adjusting groove 43, thereby locking the extended mesh plate 3. In this way, the extended mesh plate 3 will not slide or retract during subsequent adjustment, handling, or use, ensuring stability. The extension length of the protective device is determined to ensure the stability of the protection range at the construction site and improve the safety performance. When splicing is required, the construction personnel align the torsion block 52 in the fixing sleeve 51 on the adjacent extension mesh plate 3 with the locking block 54 on the protective mesh frame 1, so that the torsion block 52 is in a basically horizontal state, making it easy for the locking block 54 to slide into the locking groove 53 on the left side of the torsion block 52. After the initial connection is completed, the construction personnel rotate the turntable 562 on the front side of the threaded column 561, causing the threaded column 561 to rotate, so that the elastic clamping block 563 fixedly connected on the rear side moves into the pressing groove 55 on the front side of the locking block 54. During the internal movement, since the elastic clamping block 563 is slightly smaller than the pressure groove 55, the elastic clamping block 563 closely fits the pressure groove 55 and uses its own elasticity to generate squeezing force, firmly fixing the card block 54 in the card groove 53. This achieves a stable splicing of the extension mesh plate 3 and the protective mesh frame 1. This splicing method abandons the traditional laborious lifting and installation method, greatly reduces labor intensity, and allows construction personnel to complete the splicing work more efficiently, ensuring the standardization of installation and making the splicing of the protective device more efficient and stable, which is conducive to the widespread application of the protective device on the construction site.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
