Description

Technical Field

[0001] The present invention relates to the technical field of electric power operation and maintenance, and in particular to a novel outdoor electric power box safety guardrail device. Background Art

[0002] With the acceleration of urbanization and the increasing density of power facilities, outdoor power boxes (such as box-type transformers and cable junction boxes) are widely used in distribution networks due to their miniaturization, centralized deployment, and flexible installation. However, these devices are often installed in public places or along roadsides, posing safety risks such as electric shock and accidental contact. Therefore, current standards require that outdoor power boxes be equipped with safety railings to isolate dangerous areas and protect the public and maintenance personnel.

[0003] At present, traditional outdoor power box safety guardrails mainly adopt an integrated hard connection structure, which has the following technical defects:

[0004] ① Inconvenient transportation: The integral guardrail is large in size and heavy in weight, making it difficult to transport and carry, especially when installed at high places or in narrow spaces.

[0005] ②Poor size adaptability: The fixed structure cannot be flexibly adjusted in size according to on-site requirements.

[0006] ③Poor environmental adaptability: Traditional guardrail materials are prone to corrosion, and their structural strength decreases after long-term outdoor use, affecting the protective effect.

[0007] In response to the above problems, the industry urgently needs a new type of guardrail device that is modular, quickly installable, safe and reliable to improve the safety protection level of power facilities while optimizing operation and maintenance efficiency and economy.

[0008] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Summary of the Invention

[0009] One object of the present invention is to provide a novel outdoor power box safety guardrail device that can effectively solve the problems of existing outdoor power box safety guardrails such as inconvenient transportation, poor size adaptability, and poor environmental adaptability.

[0010] To achieve the above objectives, the present invention provides a novel outdoor power box safety guardrail device, comprising:

[0011] A plurality of anti-corrosion meshes, each of which has a storage state in which the meshes are stored in a rolled-up shape, and an unfolded state in which the meshes are unfolded to a straight shape under the action of a tension force;

[0012] A plurality of quick-install corner mechanisms, each of which wraps around two quick-install clamping assemblies and a hinge assembly that hinges the two quick-install clamping assemblies;

[0013] Each of the quick-install clamping assemblies is used to clamp and fix an end portion of the anti-corrosion grid, so that each of the anti-corrosion grids and each of the quick-install corner mechanisms encloses a box installation area for accommodating an outdoor power box.

[0014] Optionally, the anti-corrosion grid is a polyester-coated steel wire mesh;

[0015] The polyester coated steel wire mesh comprises a steel wire mesh and a PVC layer or a PE layer coated on the outer layer of the steel wire mesh.

[0016] Optionally, the PVC layer or PE layer is yellow or red.

[0017] Optionally, the hinge assembly includes a central rotating shaft and two hinge blades hinged to the central rotating shaft.

[0018] Wherein, each of the quick-release clamping components is mounted and fixed on one of the hinge blades.

[0019] Optionally, the quick-release clamping assembly is connected to the hinge blade by welding, or fastened by bolts.

[0020] Optionally, the bottom of the central rotating shaft protrudes downward relative to the two hinge blades and is provided with a tapered external thread on the circumferential surface.

[0021] Optionally, the quick-release clamping assembly includes a fixed clamping plate installed and fixed on the hinge blade, and a movable clamping plate detachably connected to the fixed clamping plate.

[0022] Optionally, at least one of the two clamping plates is provided with a hook portion and a slot for the hook portion of the other clamping plate to pass through;

[0023] The mesh size of the anti-corrosion grid is larger than the size of the hook portion so that the hook portion can pass through.

[0024] Optionally, the fixed splint and the movable splint are connected by an anti-lost rope.

[0025] The beneficial effects of the present invention are: providing a new outdoor power box safety guardrail device,

[0026] Firstly, the anti-corrosion mesh adopts a flexible structure that can be rolled up and stored, which can significantly reduce the volume during transportation. Only 1-2 people are needed to carry a single mesh, making it particularly suitable for narrow spaces or high-altitude operations.

[0027] Secondly, the quick-install corner components and anti-corrosion mesh are designed as separate components, allowing for easy individual packaging and transportation, eliminating the bulky transportation difficulties associated with traditional, integrated guardrails. More importantly, this design allows all components to be transported via standard logistics vehicles, eliminating the need for specialized heavy equipment and significantly reducing transportation costs.

[0028] During on-site assembly, the curled anti-rust mesh grid only needs to be unfolded to automatically return to a straight state. Combined with the clamping and fixing connection method of the quick-release clamping assembly, the entire guardrail system can be quickly assembled without welding.

[0029] This innovative design of "compressing volume during transportation and quickly expanding during use" perfectly overcomes the transportation and installation difficulties caused by the integrated hard-connected structure of traditional guardrails. It is particularly suitable for power facility maintenance scenarios that require frequent handling or are space-constrained, and realizes full process optimization from transportation to installation.

[0030] Therefore, the novel outdoor power box safety guardrail device provided by the present invention can effectively solve the problems of existing outdoor power box safety guardrails such as inconvenient transportation, poor size adaptability, and poor environmental adaptability.

[0046] The novel outdoor power box safety guardrail device provided by the present invention effectively solves the problems of inconvenient transportation, poor size adaptability, and poor environmental adaptability of traditional guardrails in the background art through modular design and quick assembly structure.

[0047] See also Figure 1 and Figure 2 The present invention provides a novel outdoor power box safety guardrail device, comprising:

[0048] A plurality of anti-corrosion meshes 1, each of which has a storage state in which the meshes are stored in a rolled-up shape, and an unfolded state in which the meshes are unfolded to a straight shape under the action of a tension force;

[0049] A plurality of quick-install corner mechanisms 2, each of which includes two quick-install clamping assemblies 201 and a hinge assembly 202 that articulates the two quick-install clamping assemblies 201;

[0050] Each of the quick-install clamping components 201 is used to clamp and fix an end of the anti-corrosion grid 1, so that each of the anti-corrosion grids 1 and each of the quick-install corner mechanisms 2 encloses a box installation area 3 for accommodating an outdoor power box.

[0051] The novel outdoor power box safety guardrail device provided in this embodiment works as follows:

[0052] 1. Warehousing and transportation stage

[0053] (1) Curling and storing the anti-corrosion grid 1

[0054] The anti-corrosion grid 1 is made of a flexible metal mesh (such as a galvanized steel wire mesh) or a composite material. It is curled into a cylindrical shape at the factory and fixed with straps, etc., which greatly reduces the occupied space.

[0055] The weight of a single roll of mesh is controlled at 10-20kg, which is convenient for manual handling or mechanical lifting. It is especially suitable for narrow roads or high-altitude operations (such as installing power boxes under viaducts).

[0056] (2) Split packaging of quick-install corner mechanism 2

[0057] The quick-install corner mechanism 2 (including the splint, hinge assembly 202, and fasteners) is packed and transported in standardized modules, with a single component weighing ≤5 kg.

[0058] 2. On-site assembly stage (quick installation, flexible adaptation)

[0059] (1) Expand and position the grid

[0060] The curled anti-corrosion grid 1 is spread out flatly and restored to a straight state by utilizing its own elasticity.

[0061] According to the size of the power box, determine the required number of anti-corrosion grids 1 and the enclosure shape (such as rectangle, polygon).

[0062] (2) Install the quick-release corner mechanism 2

[0063] Step 1: Insert the end of the anti-corrosion grid 1 into the gap of the quick-install clamping assembly 201 , and clamp the end of the anti-corrosion grid 1 through the quick-install clamping assembly 201 .

[0064] Step 2: Repeat the above steps to connect all anti-corrosion grilles 1 and quick-install corner mechanisms 2 to form a closed guardrail.

[0065] The novel outdoor power box safety guardrail device provided in this embodiment:

[0066] First, the anti-corrosion mesh 1 adopts a flexible structure that can be rolled up and stored, which can greatly reduce the volume during transportation. Only 1-2 people are needed to carry a single mesh, which is particularly suitable for narrow spaces or high-altitude work scenarios.

[0067] Secondly, the quick-install corner components and anti-corrosion mesh 1 are designed as separate components, allowing for easy individual packaging and transportation, eliminating the bulky transportation difficulties associated with traditional, integrated guardrails. More importantly, this design allows all components to be transported via standard logistics vehicles, eliminating the need for specialized heavy equipment and significantly reducing transportation costs.

[0068] During on-site assembly, the curled anti-rust mesh 1 can automatically return to a straight state by simply unfolding it. Combined with the clamping and fixing connection method of the quick-release clamping assembly 201, the entire guardrail system can be quickly assembled without welding.

[0069] This innovative design of "compressing volume during transportation and quickly expanding during use" perfectly overcomes the transportation and installation difficulties caused by the integrated hard-connected structure of traditional guardrails. It is particularly suitable for power facility maintenance scenarios that require frequent handling or are space-constrained, and realizes full process optimization from transportation to installation.

[0070] Therefore, the novel outdoor power box safety guardrail device provided by the present invention can effectively solve the problems of existing outdoor power box safety guardrails such as inconvenient transportation, poor size adaptability, and poor environmental adaptability.

[0071] Optionally, the anti-corrosion grid 1 is a polyester-coated steel wire mesh; the polyester-coated steel wire mesh includes a steel wire mesh, and a PVC layer or a PE layer coated on the outer layer of the steel wire mesh.

[0072] This polyester-coated steel mesh is extruded and coated with PVC or PE, creating a dual-layer protection system. The inner steel mesh provides high-strength support, while the outer polymer layer effectively isolates moisture, oxygen, and corrosive media, improving corrosion resistance by 3-5 times compared to traditional galvanized mesh. Furthermore, the insulating properties of the coating enable the mesh to withstand 10kV voltage, significantly reducing the risk of electric shock around power boxes, making it particularly suitable for high-voltage distribution sites.

[0073] Furthermore, the PVC or PE layer is yellow or red. By setting the PVC or PE layer to yellow or red, the mesh grid is given an active warning function, increasing visibility by 40% in foggy or low-light environments, significantly enhancing operational safety. Optionally, a UV absorber can be incorporated into the coating layer to ensure that the warning color remains colorfast for over five years in outdoor exposure, eliminating the need for frequent maintenance.

[0074] The stainless steel grille can be optionally painted in a reflective color to further enhance nighttime warning effectiveness. Under headlights, the reflective intensity exceeds 500 cd / lx, creating an all-weather protection system. This color customization can also be matched to the safety level requirements of different power facilities, such as red for high-risk areas and yellow for general warning areas.

[0075] In some other embodiments, the anti-corrosion grid 1 may also be a galvanized steel wire mesh, a stainless steel wire mesh, or a glass fiber reinforced plastic grid.

[0076] In this embodiment, the hinge assembly 202 includes a central rotation axis 2021 and two hinge blades 2022 hinged to the central rotation axis 2021, wherein each of the quick-release clamping assemblies 201 is mounted and fixed on one of the hinge blades 2022. The quick-release clamping assembly 201 is connected to the hinge blades 2022 by welding or fastening with bolts.

[0077] Furthermore, the bottom of the central rotating shaft 2021 protrudes downward relative to the two hinge blades 2022, and is provided with a tapered external thread on the circumferential surface. The design of the bottom of the central rotating shaft 2021 protruding downward forms a positioning pile structure, which increases the anti-overturning torque of the guardrail by 300% after being inserted into the ground, and can withstand the impact of strong winds without additional reinforcement. Optionally, the protrusion adopts a tapered external thread design, which can be screwed into the hard ground for fixation, and can also be used as an interface of the counterweight box to connect the concrete base or the water-filled counterweight module to achieve rapid and stable installation of temporary facilities. This structure also has a guiding function, which can automatically correct the vertical deviation during construction in soft soil foundations to ensure the overall installation accuracy of the guardrail. So that it can be inserted into the soil or weighted base, thereby realizing the positioning of the new outdoor power box safety guardrail device.

[0078] In this embodiment, the quick-release clamping assembly 201 comprises a fixed plate 201a mounted on the hinge blade 2022, and a movable plate 201b detachably connected to the fixed plate 201a. At least one of the two plates is provided with a hook portion 2011 and a slot for the hook portion 2011 of the other plate to pass through. The mesh size of the anti-corrosion grid 1 is larger than that of the hook portion 2011 to facilitate its passage.

[0079] The interlocking structure of the hook 2011 and the slot creates a mechanical self-locking mechanism, ensuring a pull-out resistance of 800N at the connection point. The clever design of a mesh with a larger size than the hook allows the hook to penetrate the mesh for bidirectional locking, eliminating the risk of loosening even in vibrating environments. The bidirectional buckle design enables blind operation, ensuring reliable secure attachment without the need for visual alignment during installation, making it particularly suitable for emergency repairs at night or in low visibility. The structure also features a self-cleaning feature, with the hook scraping away dust accumulated in the mesh during movement, preventing problems with long-term use.

[0080] Furthermore, the fixed splint 201a and the movable splint 201b are connected by an anti-lost rope 203. Optionally, the anti-lost rope 203 is made of Kevlar fiber material, which can withstand more than 200 opening and closing operations without breaking, completely solving the problem of small parts being lost.

[0081] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
