Description

Technical Field

[0001] The present invention relates to the technical field of safety protection for electric power high-altitude operations, and in particular to a protective device for preventing electric poles from falling objects and injuring people, and a working method thereof. Background Art

[0002] In power systems, 10kV poles are common transmission infrastructure, supporting and securing power lines and related equipment. When installing and maintaining equipment such as circuit breakers, drop switches, and voltage transformers on poles, workers must work at height, creating the risk of falling tools, materials, and other objects. Falling objects can not only cause serious injuries to personnel on the ground but can also damage equipment and delay construction. Therefore, ensuring safety during high-altitude operations and preventing injuries from falling objects are crucial requirements for the power industry.

[0003] Currently, common measures to prevent falling objects during overhead power operations include using safety ropes to tie tools to the operator or to the pole, and installing safety fences around the pole. While safety ropes can prevent falling tools to a certain extent, in practice, their use can be limited by the frequent movement and use of multiple tools by operators, and they cannot completely prevent tools from accidentally falling. Safety fences primarily prevent unauthorized access to the danger zone and are limited in their effectiveness against falling objects. These measures are less effective in complex working environments, such as crowded areas. Furthermore, the operator on the pole must tie materials (tools or waste) to the ropes and then slowly lower them down the pole using the ropes. The specific process involves the operator on the pole securing the material to the ropes; lowering the ropes while controlling the speed; after the material hits the ground, the operator on the ground unties and recovers it; then pulling the ropes back upwards; and repeating the process.

[0004] Therefore, the prior art has the following technical problems:

[0005] First, while using a safety rope can connect tools to workers or poles, when workers frequently move and operate multiple tools, the rope can become entangled or interfere with their work, making it inconvenient and reducing work efficiency. Second, safety fences only restrict access to dangerous areas and cannot effectively intercept materials falling from heights. Furthermore, the rope descent requires coordination between personnel on the pole and on the ground. If the lashing is not secure or coordination fails, materials can easily fall mid-air, causing injuries. Furthermore, the amount of material transferred at a time is limited, and frequent tying and untying significantly increases equipment installation time, resulting in low construction efficiency.

[0031] It should be noted that the following detailed description is illustrative and is intended to further illustrate the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] Example 1

[0033] like Figure 1 、 Figure 2 As shown, this embodiment proposes a protective device for preventing falling objects from injuring people on an electric pole 4, the protective device includes a storage umbrella 2 and a storage tube 3; the storage umbrella 2 can be hung on the pole tower cross arm 41, and the side of the storage umbrella 2 has a first opening and closing line 23, and when the first opening and closing line 23 is closed, the storage umbrella 2 is funnel-shaped and can be sleeved on the outer periphery of the electric pole 4; the upper end of the storage tube 3 is connected to the bottom end of the storage umbrella 2, and the side of the storage tube 3 has a second opening and closing line 31, and when the second opening and closing line 31 is closed, the storage tube 3 is sleeved on the outer periphery of the electric pole 4, and a storage belt 32 is provided at the bottom end of the storage tube 3, and the storage belt 32 can tie the bottom end of the storage tube 3 to the electric pole 4.

[0034] The storage umbrella 2 is installed on the cross arm 41 at the top of the pole 4. When closed, it forms a funnel-shaped structure. This design, unlike traditional flat safety nets, can expand the scope of reception and has an automatic diversion function. It can effectively guide tools, materials and other objects dropped from high altitudes to the opening at the bottom of the umbrella to prevent them from scattering and improve collection efficiency. The storage belt 32 at the bottom of the storage tube 3 provides the final fixed anchor point for the device, ensuring that the entire system remains stable in position under stress or wind load and is not easily displaced. The integrated umbrella-tube design realizes a "receiving-collecting-fixing" closed loop, effectively solving the problem of personal injury caused by falling objects from high altitudes. At the same time, it avoids the frequent transfer of waste materials by people on the pole, improves storage efficiency, and reduces operational interference.

[0035] The storage umbrella 2 includes an upper support ring 21, an umbrella surface 22 and a lower support ring 24. The diameter of the upper support ring 21 is larger than the diameter of the lower support ring 24. The upper end of the umbrella surface 22 is connected to the upper support ring 21, and the lower end of the umbrella surface 22 is connected to the lower support ring 24.

[0036] The diameter of the upper support ring 21 is larger than that of the lower support ring 24, so that the entire umbrella cover 22 is naturally folded, which is more conducive to expanding the range of receiving falling objects and enhancing the object's conductivity, so that objects falling from different positions can be effectively captured, so that the fallen objects can naturally slide into the storage tube 3 without the need for secondary guidance during the sliding process, achieving "natural storage" of objects, and improving the guidance and collection efficiency of the protective device for falling objects. The upper and lower ends of the umbrella cover 22 are respectively connected between the two support rings to form a tension structure, reducing the possibility of deformation and damage of the umbrella cover 22 due to the impact of heavy objects, effectively enhancing the reliability of the device. The umbrella cover 22 is made of high-strength waterproof fabric, which can not only receive metal tools, but also withstand certain wind speeds and rain impacts, enhancing the all-weather applicability of the device.

[0037] The upper support ring 21 is circular as a whole, with a rotatable stud 25 at one end and a threaded sleeve 26 at the other end. The stud 25 is installed in the threaded sleeve 26 to make the upper support ring 21 form a complete circle. The structure of the lower support ring 24 is the same as that of the upper support ring 21, and the two only differ in diameter.

[0038] The detachable structure of the stud 25 and the screw sleeve 26 facilitates the flexible disassembly and assembly of the support ring when installing or disassembling the storage umbrella 2, thereby improving the convenience of operation and ensuring the stability of the support ring during use. It can better maintain the shape of the storage umbrella 2 and ensure that it can normally play the role of receiving and guiding falling objects. The upper support ring 21 and the lower support ring 24 have the same structure, which unifies the design of the components and facilitates production and maintenance.

[0039] The storage umbrella 2 is hung on the pole tower cross arm 41 through the hanging assembly 1. The hanging assembly 1 includes a safety hook 11 and a hanging chain 12. The safety hook 11 is hung on the pole tower cross arm 41. The upper end of the hanging chain 12 is connected to the safety hook 11, and the lower end of the hanging chain 12 is connected to the upper support ring 21.

[0040] The safety hook 11 is attached to the tower crossarm 41, forming the first stable anchor point. The hanging chain 12 connects the safety hook 11 to the support ring, suspending the umbrella. This precisely positions the canopy 22 directly below the operating point, maximizing its interception area and avoiding blind spots caused by installation deviations. The overall structure completes the attachment path from the tower crossarm 41 to the support ring, providing a stable foundation for the subsequent opening of the canopy 22 and docking with the storage tube 3.

[0041] like Figure 1As shown, the hanging chain 12 has an upper section and a lower section. The upper hanging chain 12 has one, which is connected to the safety hook 11. The lower hanging chains 12 have multiple, and the upper ends of the multiple lower hanging chains 12 are all connected to the upper hanging chain 12, and the lower ends of the multiple lower hanging chains 12 are evenly connected to different circumferential points of the upper support rod.

[0042] The multi-point evenly distributed hanging design makes the storage umbrella 2 more evenly stressed, and can better transfer the weight of the storage umbrella 2 and the impact force caused by the falling object to the safety hook 11 and the pole tower cross arm 41. Especially at the moment when the object falls, it can effectively disperse the impact force, avoid deformation, tearing or falling off of the umbrella cover 22 in a certain direction due to concentrated force, and greatly enhance the structural safety of the umbrella cover 22.

[0043] Both the first and second opening / closing lines 23, 31 are zippers. Zippers, as closure structures, offer tight closure, quick opening and closing, and high strength, making them suitable for outdoor use. Compared to Velcro and other fasteners, zippers are less likely to come loose in the face of impact from falling objects or wind loads. By using zippers as the opening and closing structure, the device can be flexibly deployed before operation and quickly stowed afterward, improving work efficiency and operational safety.

[0044] The storage tape 32 is self-adhesive. It's easy to use, securely adheres, and is reusable. When securing the bottom end of the storage tube 3 to the pole 4, the tape adheres tightly to the surface of the pole 4, eliminating the need for complex tools or devices. This allows for quick, secure binding, saving installation time and improving work efficiency.

[0045] For tools (such as screwdrivers, pliers) and recyclable electrical components (such as voltage transformers), they will collide with each other after falling or collide with the pole 4 during the falling process, thereby causing damage. Based on this, the protective device of this embodiment is further provided with an isolation component 5, such as Figure 3 As shown, the isolation assembly 5 includes an isolation rod 51 and an isolation layer 52, the two ends of the isolation rod 51 are connected to the inner wall of the upper support ring 21, the upper end of the isolation layer 52 is connected to the isolation rod 51, the side of the isolation layer 52 is connected to the umbrella surface 22 of the storage umbrella 2 and the tube wall of the storage tube 3, the bottom of the isolation layer 52 is connected to the tube wall of the storage tube 3, and the isolation assembly 5 and the storage umbrella 2 and the storage tube 3 form an isolation compartment 53.

[0046] The isolation assembly 5 is mainly used to isolate and collect tools and recyclable electrical components that are easily damaged by falling and collisions from ordinary waste materials during the falling process. Tools and recyclable electrical components are collected through the isolation chamber 53. When a tool or electrical component falls, it is taken out through the discharge port at the bottom, and then another tool or electrical component is lowered. When such items fall into the isolation chamber 53, they can avoid collisions with other items or electric poles 4 and cause damage, thus achieving lossless recycling, improving the recycling rate of items, and reducing loss costs. Waste materials can fall directly through the compartments outside the isolation chamber 53, optimizing the spatial layout and functional zoning inside the protective device, enabling it to be classified, collected, and processed for different types of falling objects, thereby improving the overall performance of the protective device.

[0047] A discharge port is provided on the wall of the storage tube 3, and the discharge port is located at the bottom of the isolation bin 53. An opening and closing door 33 is provided on the discharge port, and the opening and closing door 33 is attached to the wall of the storage tube 3 by Velcro or magnetism.

[0048] When it is necessary to take out the tools, electrical components and other items collected in the isolation bin 53, the removal operation can be performed directly by opening the discharge port opening and closing door 33. The opening and closing door 33 controls the release of objects from the isolation bin 53 one by one, effectively avoiding collisions and management difficulties caused by the concentrated release of multiple objects; there is no need to remove the entire storage tube 3 or perform large-scale disassembly, which improves the convenience and efficiency of operation.

[0049] The use of Velcro or magnetic attachment makes the opening and closing operation of the opening and closing door 33 simple and quick, and can ensure the sealing and stability when closed. It is also convenient to flexibly adjust the opening and closing state of the opening and closing door 33 according to actual needs, further improving the performance of the protective device during the collection, temporary storage and retrieval of items.

[0050] Example 2

[0051] This embodiment provides a method for operating the falling object protection device for the electric pole 4 as described in Example 1, including:

[0052] The funnel-shaped storage umbrella 2 suspended on the tower cross arm 41 is used to receive objects falling from a high altitude, and then the objects are made to slide along the slope of the umbrella surface 22 into the storage tube 3 connected to the bottom of the umbrella surface 22 .

[0053] Differentiate the processing objects: recyclable objects and objects that need to be protected are introduced into the isolation bin 53 and taken out individually from the discharge port at the bottom of the isolation bin 53; objects that do not need to be recycled directly fall into the buffer zone at the bottom of the storage tube 3 through the non-isolation area for centralized processing.

[0054] The entire working method includes: interception, diversion, storage, classification, and removal. It gives full play to the structural characteristics and functional advantages of each part of the protective device, and classifies and processes the objects according to their properties and protection needs. It not only effectively prevents falling objects from high altitude from injuring people, but also realizes the reasonable collection and management of different items, improves the safety and work efficiency of the work site, and echoes the various structural characteristics of the protective device. It can be widely used in high-altitude power operation scenarios such as 10kV poles 4.

[0055] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
