Description

Technical Field

[0001] This invention relates to the field of construction protection technology, specifically a portable protective device for power construction. Background Technology

[0002] Power construction is a critical operation to ensure the safe and stable operation of the power system, as well as to carry out the construction, expansion, renovation and maintenance of the power grid. It involves multiple links such as the erection of transmission and distribution lines, the laying of cables, the installation and commissioning of substation equipment, and emergency repair of faults. The quality and efficiency of power construction are related to the normal order of production and life and the reliability and economy of the power grid.

[0003] When carrying out power construction, especially temporary construction in densely populated areas, it is necessary to set up protective devices around the construction area to isolate the work area and warn pedestrians and vehicles. Existing protective devices are mostly fixed barriers and fences, which lack flexibility. The rigid barrier components lack storage design, making transportation, storage and frequent handling between different construction sites very inconvenient. The protective devices have relatively simple functions and cannot support and protect temporarily laid cables and wires. Summary of the Invention

[0004] The purpose of this invention is to provide a portable protective device for power construction, so as to solve the problem of inconvenience in using existing protective devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A portable protective device for power construction includes a support frame and further includes:

[0007] The movable frame has fixed blocks on both sides of the support frame, rotating plates on the fixed blocks, and rotating shafts at both ends of the rotating plates. Multiple rotating plates are connected in series by hinges at both ends of the rotating shafts to form a foldable and unfoldable guardrail body. Two guardrail bodies are symmetrically arranged on both sides of the support frame. A movable frame is provided on the side of the guardrail body away from the support frame. A support plate is provided at the bottom of the movable frame, and multiple rollers are provided on the support plate.

[0008] The limiting assembly includes a sleeve disposed outside the support frame and the movable frame, a support rod disposed between the two sleeves, and a support block in contact with the outside of the support rod. A hinge rod is disposed at the center of the rotating plate, a movable plate is disposed at one end of the hinge rod, a telescopic sleeve is disposed outside the movable plate, and a support block is disposed at one end of the telescopic sleeve.

[0009] The support assembly includes a protective plate disposed inside the support frame, multiple support sleeves disposed on the protective plate, a lifting rod disposed at the top of the support sleeve, and a horizontal plate disposed at the top of the lifting rod. The horizontal plate has multiple wire passage grooves. The lifting rod is provided with a sleeve on the outside. The sleeve has an mounting plate on its side wall. The mounting plate has multiple rotating rollers.

[0010] The transmission mechanism is located between the protective plate and the hinge rod. The movable frame moves away from the support frame and drives multiple rotating plates to unfold outward to form the protective railing body. The horizontal plate supports and protects the cable through the cable groove on it.

[0011] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0012] In one alternative embodiment: the transmission mechanism includes a pressure plate, a connecting plate, and a transmission groove. The connecting plate is slidably disposed on the fixed block. The connecting plate is rotatably connected to the hinge rod. The transmission groove is provided on one side of the connecting plate that penetrates into the support frame. A pressure plate is disposed at the bottom of the protective plate, and the pressure plate is in contact with the transmission groove.

[0013] In one alternative: the movable frame has a slot on its side wall, one end of the rotating plate passes through the movable frame and is provided with a guide block, the guide block is slidably disposed inside the movable frame, and a locking block is slidably disposed on the side wall of the guide block, the locking block slidably passing through the slot.

[0014] In one alternative: the movable frame has a mounting block on its side wall, a rotating frame is mounted on the mounting block, a rod is mounted on the outside of the rotating frame, a connecting block is mounted between two rods, and a threaded sleeve is mounted on the connecting block.

[0015] In one alternative: a lead screw is provided inside the threaded sleeve, one end of the lead screw is rotatably connected to the rotating frame, and the other end of the lead screw is provided with a turntable.

[0016] In one alternative: a locking bolt is provided on the outside of the telescopic sleeve, and one end of the locking bolt is connected to the movable plate.

[0017] In one alternative: a fixed frame is provided on the outside of the support frame, a movable tube is rotatably provided inside the fixed frame, a reinforcing rod is provided at the bottom end of the movable tube, and a storage hole that cooperates with the reinforcing rod is provided inside the fixed frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] Portable power construction protective devices utilize a movable frame, rotating plate, and locking slots to adjust the length of the guardrail body. This allows for adjustments to the isolation area based on site requirements, overcoming the limitations of traditional fixed guardrails in narrow spaces and improving the device's site adaptability. Reinforcing rods on the support frame enhance lateral stability, while support blocks tighten against the support rods, providing central support and preventing guardrail sagging. This improves the overall structure's impact and toppling resistance, ensuring construction safety. Height-adjustable rotating rollers facilitate cable guidance and redirection, combining area isolation and cable protection into one function, reducing equipment investment and optimizing site layout.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] like Figure 1-8 As shown, a portable protective device for power construction provided in one embodiment of the present invention includes a support frame 1, and further includes:

[0032] The movable frame 2 has fixed blocks 26 on both sides of the support frame 1. The fixed blocks 26 are fixedly mounted on the support frame 1. Each fixed block 26 has two sets of rotating plates 11 rotatably mounted on it. Each rotating plate 11 has a rotating shaft 10 at both ends. Multiple rotating plates 11 are connected in series by hinges at both ends through the rotating shafts 10 to form a foldable and unfoldable guardrail body. Two guardrail bodies are symmetrically arranged on both sides of the support frame 1. The movable frame 2 is located on the side of the guardrail body away from the support frame 1. Pulling the movable frame 2 outward can unfold the entire guardrail body, thereby isolating the construction area. The bottom of the movable frame 2 is equipped with a support plate 3, and multiple rollers 4 are provided on the support plate 3 to facilitate the movement and positioning of the movable frame 2.

[0033] The limiting assembly includes a sleeve 13 disposed outside the support frame 1 and the movable frame 2, a support rod 14 disposed between the two sleeves 13, and a support block 151 in contact with the outside of the support rod 14. The sleeve 13 is rotatably mounted on the support frame 1 and the movable frame 2. The support rod 14 is elastically connected to the sleeve 13 through an elastic element (such as a spring), so that the support rod 14 has a certain buffering and adjustment capacity. The center positions of the two rotating plates 11 are rotatably connected by a rotating shaft. A hinge rod 17 is provided on the side of the two rotating plates 11 that are far apart. One end of the hinge rod 17 is fixedly connected to the adjacent rotating plate 11. The other end of the hinge rod 17 is provided with a movable plate 16. When the guardrail body is unfolded, the two adjacent rotating plates 11 at the center rotate in opposite directions, thereby driving the two hinge rods 17 fixed thereto to also rotate in opposite directions. The movable plate 16 is fixedly disposed on the hinge rod 17. The other end of the movable plate 16 is fixedly connected to the telescopic sleeve 15. The end of the telescopic sleeve 15 is provided with the support block 151.

[0034] The support assembly includes a protective plate 24 disposed inside the support frame 1, a plurality of support sleeves 23 disposed on the protective plate 24, a lifting rod 19 disposed at the top of the support sleeve 23, and a horizontal plate 18 disposed at the top of the lifting rod 19. The horizontal plate 18 has a plurality of cable grooves 181 for supporting and separating different types of cables. The lifting rod 19 is also fitted with a sleeve 20 that can be adjusted up and down along it. The side wall of the sleeve 20 is fixed with an mounting plate 21. A plurality of rotating rollers 22 for guiding the direction of the cables are mounted on the mounting plate 21.

[0035] A transmission mechanism is located between the protective plate 24 and the hinge rod 17. The movable frame 2 moves away from the support frame 1 and drives multiple rotating plates 11 to unfold outward to form the guardrail body. The horizontal plate 18 supports and protects the cable through the cable groove 181 on it. After the guardrail body unfolds outward and is fixedly installed, the protective plate 24 moves downward under its own weight and external pressure, thereby driving the transmission mechanism connected to it to move. The transmission mechanism drives the two sets of connecting plates 25 to move away from each other. The connecting plates 25 push the hinge rod 17 to move away from the support frame 1, thus transmitting the load acting on the protective plate 24. The rotation of the rotating plate 11 is distributed throughout the entire unfolded guardrail body, enhancing the overall structural stability and anti-overturning ability. During the unfolding process of the guardrail body, the rotation of the rotating plate 11 is transmitted to the movable plate 16 through the hinge rod 17, causing it to flip. The other end of the movable plate 16 pushes the support rod 14 upward through the telescopic sleeve 15 and the support block 151. The support rod 14 is pushed upward, and the hinge rod 17 drives the guardrail plate 24 to rise through the sleeve 13, thereby providing additional support for the unfolded guardrail body, preventing it from falling due to its own weight or external force, and ensuring the flatness and stability of the guardrail body.

[0036] like Figure 1-6As shown in the preferred embodiment of the present invention, the transmission mechanism includes a pressure plate 29, a connecting plate 25, and a transmission groove 251. The connecting plate 25 is slidably disposed on the fixing block 26. The connecting plate 25 is rotatably connected to the hinge rod 17. The connecting plate 25 has a transmission groove 251 on one side that penetrates into the support frame 1. The bottom of the protective plate 24 is provided with a pressure plate 29. The lower end of the pressure plate 29 contacts the inner wall of the transmission groove 251. When the guardrail body is unfolded and bears load, the protective plate 24 moves downward under force, causing the pressure plate 29 to move downward synchronously. Since the lower end of the pressure plate 29 is located in the inclined transmission groove 251, its downward vertical movement is converted into a force that pushes the connecting plate 25 to slide horizontally through the inclined surface of the groove wall. This drives the two connecting plates 25 to move away from each other, thereby pushing the hinge rod 17, which is hinged to it, to move. This effectively transfers and distributes the vertical load borne by the protective plate 24 to the entire unfolded guardrail body structure.

[0037] like Figure 1-6 As shown, in a preferred embodiment of the present invention, the movable frame 2 has a slot 201 on its side wall. The slot 201 consists of a vertical slot and multiple horizontal slots connected thereto. One end of the rotating plate 11 is inserted into the movable frame 2 and a guide block 28 is rotatably provided thereon. The guide block 28 can only move horizontally. The guide block 28 is slidably disposed inside the movable frame 2. A locking block 12 is slidably disposed on the side wall of the guide block 28. The locking block 12 slides into the slot 201. When the guardrail body is unfolded outward to adjust the isolation range, the guide block 28 slides up and down along the inner wall of the movable frame 2. When adjusted to the desired position, the locking block 12 on the guide block 28 is pushed horizontally. The locking block 12 slides into the corresponding horizontal slot of the slot 201, locking the movable frame 2 and the guardrail body in the designated position, effectively preventing them from retracting during construction and ensuring the stability of the protected area.

[0038] like Figure 1-6 As shown, in a preferred embodiment of the present invention, a mounting block 5 is fixedly provided on the side wall of the movable frame 2, a rotating frame 6 is rotatably provided on the mounting block 5, an insert rod 7 is slidably provided on the outside of the rotating frame 6, a connecting block 8 is fixedly provided between the two insert rods 7, and a threaded sleeve 801 is provided on the connecting block 8. After the protective device is positioned and installed, the rotating frame 6 rotates downward and inserts the insert rod 7 downward into the ground, thereby providing additional anchoring support for the entire movable frame 2 and enhancing its impact resistance and anti-tipping ability.

[0039] like Figure 1-6As shown, in a preferred embodiment of the present invention, a lead screw 9 is provided inside the threaded sleeve 801. One end of the lead screw 9 is rotatably connected to the rotating frame 6, and the other end of the lead screw 9 is provided with a turntable 901. Rotating the turntable 901 drives the lead screw 9 to rotate, and the threaded transmission controls the insertion rod 7 to slide vertically along the rotating frame 6, thereby realizing the fine adjustment of the support height, so that the insertion rod 7 can adapt to the ground with different hardness and ensure stable support.

[0040] like Figure 1-5 As shown, in a preferred embodiment of the present invention, a locking bolt 27 is provided on the outside of the telescopic sleeve 15. One end of the locking bolt 27 is connected to the movable plate 16. Tightening the locking bolt 27 causes its end to press against the inner tube of the telescopic sleeve 15, thereby locking the telescopic length of the telescopic sleeve 15 and fixing the relative position between the movable plate 16 and the support block 151.

[0041] like Figure 1 As shown in the preferred embodiment of the present invention, the support frame 1 is provided with a fixed frame 31 on the outside, and a movable tube 32 is rotatably provided inside the fixed frame 31. A reinforcing rod 33 is provided at the bottom end of the movable tube 32. The reinforcing rod 33 is threadedly engaged with the movable tube 32. The fixed frame 31 is provided with a storage hole 34 that cooperates with the reinforcing rod 33. The reinforcing rod 33 is unscrewed and supported on the ground to provide lateral support force for the support frame 1, further improving the overall stability. After use, the reinforcing rod 33 is retracted and its bottom end is embedded in the storage hole 34 to achieve storage and facilitate transportation.

[0042] The above embodiments of the present invention provide a portable protective device for power construction. The protective device, in its folded and stored state, is transported to the construction area. Two movable frames 2 are pulled outwards (away from the support frame 1). The movable frames 2 move via rollers 4 at their bottom, causing multiple rotating plates 11 to unfold, forming a protective barrier body symmetrical to both sides of the support frame 1, defining an isolation area. The locking blocks 12 on the sidewalls of the guide block 28 slide into the corresponding horizontal grooves of the locking slots 201, thereby locking the movable frame 2 to the protective barrier body and achieving multi-level adjustment of the isolation length. The rotating frame 6 mounted on the movable frame 2 is rotated downwards, and the rotating disc 901 rotates, causing the connecting block 8 and two insert rods 7 to slide downwards along the rotating frame 6 via the threaded sleeve 801 until the tips of the insert rods 7 are firmly inserted into the ground, providing anchor support for the movable frame 2. The reinforcing rod 33 is unscrewed from the fixed frame 31, and the bottom support... Supported on the ground, it provides lateral stability for the support frame 1. As the guardrail body is fully extended and bears the load, the protective plate 24 inside the support frame 1 moves downward under pressure, and the pressure plate 29 at the bottom of the protective plate 24 descends accordingly, pressing into the transmission groove 251 of the connecting plate 25, driving the two connecting plates 25 to move away from each other. The connecting plate 25 drives the hinge rod 17 to move, and the support block 151 at the end of the telescopic sleeve 15 pushes the support rod 14 upward to provide central support for the guardrail body. Pulling up or pressing down the horizontal plate 18 drives the lifting rod 19 to move to a suitable position within the support sleeve 23. The construction cable is placed in the cable groove 181 of the horizontal plate 18 for support and isolation. The height of the sleeve 20 on the lifting rod 19 is adjusted and fixed by the fixing bolt 30, so that the cable is laid on the rotating roller 22 of the mounting plate 21 for guidance and to avoid cable wear. After construction is completed, the insert rod 7 and the reinforcing rod 33 are retracted in sequence, the locking block 12 on the movable frame 2 and the locking bolt 27 on the telescopic sleeve 15 are loosened, and the movable frame 2 is pushed inward. Each rotating plate 11 then folds and retracts around the hinge of the rotating shaft 10 in sequence.

[0043] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
