Description

Technical Field

[0001] This invention relates to the field of power emergency repair lighting equipment technology, and in particular to an emergency repair lighting device. Background Technology

[0002] Emergency repair operations often occur in sudden situations, such as natural disasters or equipment failures, which are usually accompanied by insufficient lighting. Lighting devices can provide the necessary illumination to ensure that repair personnel can clearly see the work area, enabling them to make accurate judgments and take appropriate actions, and avoiding safety accidents caused by poor visibility.

[0003] Chinese invention patent CN117432986B discloses a mobile power emergency repair lighting device, including a lighting platform set on a horizontal plane, with a center-of-gravity balancing device on top of the lighting platform. This invention adjusts the lighting range by regulating the positional distribution of several lighting components. Simultaneously, a second balancing component controls several counterweights to move synchronously, ensuring that the lighting components and counterweights are always symmetrically positioned and correspond one-to-one. This guarantees that the device remains in a state of center-of-gravity balance during the adjustment of the lighting range, preventing the device from tipping over due to excessive weight on one side. Furthermore, the device has a compact overall structure, facilitating passage in relatively narrow environments.

[0004] While the above-mentioned solution improves work efficiency to some extent when using lighting devices during emergency repairs, in actual use, the existing solution only solves simple problems through complex structures. Adding sufficient counterweights to the bottom of the device can ensure the stability of the lighting platform's center of gravity and prevent swaying or overall tipping. However, since the supporting parts of the lighting components are single-structure rods, they are prone to swaying in strong winds. This causes the lights located at high positions to sway, resulting in poor wind resistance. This not only affects the lighting effect but may also damage the lights themselves, shortening their lifespan. Furthermore, the swaying of a single light can be transmitted to the entire device, leading to a decrease in the overall stability of the device. Summary of the Invention

[0005] This application provides an emergency repair lighting device, which solves the technical problems of poor wind resistance, reduced lighting effect and poor overall stability in the prior art, and achieves the technical effects of improved wind resistance, improved lighting effect and improved overall stability.

[0006] This application provides an emergency repair lighting device, including a lighting platform, a plurality of universal self-locking wheels fixed at the bottom of the lighting platform, a plurality of lighting components fixed above the lighting platform, and wind-resistant components for dispersing and resisting wind force on the lighting components;

[0007] The wind-resistant component is rotatably connected to the outside of the lighting component through a sleeve; the cross-section of the wind-resistant component is a triangular structure, and a tail flag is fixed on one side. Under the action of wind, the tail flag drives the wind-resistant component to deflect at an angle, so that the tip of the cross-section of the wind-resistant component points to the direction of the wind, which is used to disperse and resist the wind force.

[0008] Furthermore, the lighting assembly includes a telescopic pole and a lighting lamp;

[0009] The telescopic rod is a telescopic adjustment structure, vertically fixed to the lighting platform, used to adjust the height of the lighting lamp; the lighting lamp is rotatably connected to the telescopic end of the telescopic rod, used for lighting in emergency situations.

[0010] Furthermore, the wind-resistant component includes a first sleeve, a second sleeve, a hinged seat, a flapping plate, a tail flag, and an airbag;

[0011] The first sleeve is mounted on the telescopic rod; the second sleeve is rotatably connected to the outside of the first sleeve via a bearing; the hinge seat is fixed on the second sleeve; two flipping plates are provided, arranged in a mirror image, and rotatably connected to the hinge seat respectively, the two flipping plates and the airbag together forming a triangular cross-section; the tail flag is a triangular structure, placed vertically, and fixed to the second sleeve via a connecting rod, opposite to the hinge seat; the airbag is fixed to the second sleeve via a connecting plate and located between the two flipping plates.

[0012] Furthermore, the two flipping plates are arc-shaped and connected by a windproof cloth, which is made of a flexible and elastic material.

[0013] Furthermore, the airbag is connected to an external air pump via a pipe. The airbag has an elliptical cross-section and expands along its long axis, thereby pushing the flipping plate to rotate and changing the angle between the two flipping plates.

[0014] Furthermore, both of the aforementioned flipping plates are rotatably connected to the hinge seat via ball joints, and the side of each flipping plate closest to the airbag is connected to both sides of the top of the airbag via connecting blocks.

[0015] Furthermore, the airbag includes multiple vertically arranged small airbags, the volume of which increases sequentially from top to bottom when fully inflated, forming a stepped inclined structure. This causes the flipping plates on both sides to flip about the hinge point of the hinge seat and the connecting block as the axis, thus making the flipping plates inclined.

[0016] Furthermore, each of the lighting components is provided with a support rod between itself and the lighting platform. The support rod is an elastic telescopic structure, with its fixed section connected to the lighting platform by a hinge, and its telescopic section slidably connected to the telescopic rod by a ring. The ring is fixed to the telescopic rod by a fixing bolt, which is used to fix the position of the support rod according to the change of the lighting height, and to support the lighting component through the ring.

[0017] Furthermore, multiple position holes are evenly provided on the outer side of the telescopic rod fixing section along its length.

[0018] Furthermore, multiple wind-resistant components are provided, each fixed to a position hole at a corresponding height position by locking bolts. The multiple wind-resistant components and the support rod work together to provide multi-point support for the lighting assembly, so as to ensure the overall stability of the lighting assembly.

[0019] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0020] By setting up a triangular cross-section wind-resistant component and guiding it with a tail flag, the wind-resistant component automatically adjusts its direction in strong winds. By dynamically adjusting the windward side of the wind-resistant component, its tip always points in the wind direction, regardless of the direction the wind blows. This minimizes the impact of wind resistance and wind force, effectively reducing the impact of wind resistance on the equipment and improving its wind resistance stability. It effectively solves the technical problems of poor wind resistance, reduced lighting effect, and poor overall stability in existing technologies, achieving the technical effects of improved wind resistance, improved lighting effect, and improved overall stability.

[0033] Please see Figure 1The above is a schematic diagram of the overall structure of an emergency repair lighting device of the present invention. The emergency repair lighting device of this application sets up a wind-resistant component 200 with a triangular cross section, and drives the wind-resistant component 200 to automatically adjust its direction in strong wind environment by the guidance of the tail flag 250, dynamically adjusts the windward surface of the wind-resistant component 200, minimizes the impact of wind resistance and wind force, effectively reduces the impact of wind resistance on the equipment, and achieves the technical effects of improved wind resistance, improved lighting effect and improved overall stability.

[0034] Example 1: As Figures 1 to 4 As shown, this application discloses an emergency repair lighting device, including a lighting platform 100. The bottom of the lighting platform 100 is fixed with a plurality of universal self-locking wheels 110, and a plurality of lighting components 120 are fixed on the top of the lighting platform 100. The lighting components 120 are provided with wind-resistant components 200 for dispersing and resisting wind force.

[0035] The wind-resistant component 200 is rotatably connected to the outside of the lighting component 120 via a sleeve 210;

[0036] The wind-resistant component 200 has a triangular cross-section, and a tail flag 250 is fixed on one side. Under the action of wind, the tail flag 250 drives the wind-resistant component 200 to deflect at an angle, so that the tip of the cross-section of the wind-resistant component 200 points in the direction of the wind, which is used to disperse and resist the wind force.

[0037] The lighting assembly 120 includes a telescopic rod 121 and a lighting lamp 122;

[0038] The telescopic rod 121 is a telescopic adjustment structure, vertically fixed on the lighting platform 100, and is used to adjust the height of the lighting lamp 122; the lighting lamp 122 is rotatably connected to the telescopic end of the telescopic rod 121 and is used for lighting in emergency situations.

[0039] The lighting platform 100 is a platform with uniform weight, which can ensure that the overall center of gravity of the device is stable when the device is tilted, and that the bottom of each lighting component 120 is stable and will not shift as a whole. All of these are existing technologies and will not be described in detail here.

[0040] In actual operation, the steps of this embodiment are as follows: First, the lighting platform 100 is moved to the designated position by the universal self-locking wheel 110, and the universal self-locking wheel 110 is locked to fix the device; then, according to the needs of the emergency, the height of the telescopic rod 121 is adjusted so that the lighting lamp 122 reaches a suitable lighting height; finally, when encountering strong winds, the tail flag 250 drives the sleeve 220 to rotate inside the sleeve 210 under the action of the wind, so that the tip of the cross section of the wind-resistant component 200 automatically points to the direction of the wind. The triangular cross section of the wind-resistant component 200 effectively disperses and resists the wind force by pointing its tip to the wind direction, reducing the impact of wind resistance on the equipment.

[0041] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0042] This application sets up a wind-resistant component 200 with a triangular cross-section and uses the tail flag 250 to guide and drive the wind-resistant component 200 to automatically adjust its direction in strong wind environments. By dynamically adjusting the windward side of the wind-resistant component 200, its tip always points in the wind direction, regardless of which direction the wind blows from, thus minimizing the impact of wind resistance and wind force. This effectively reduces the impact of wind resistance on the equipment, improves the wind resistance stability of the equipment, effectively reduces the swaying of the lighting lamp 122 and the telescopic pole 121, ensures the stability of the lighting effect, and ensures that the lighting lamp 122 continues to work normally in severe weather.

[0043] Meanwhile, when the apex of the triangle faces the wind, the airflow is diverted to both sides, creating a laminar separation effect that significantly reduces frontal wind pressure. Simultaneously, the turbulence intensity in the wake region is weakened, avoiding the risk of structural resonance caused by periodic vortex shedding, thus improving equipment stability. When subjected to wind force, the triangular structure can more effectively disperse and resist wind pressure, reducing swaying and deformation caused by wind. The design of the wind-resistant component 200 not only reduces the mechanical stress of wind on the lighting equipment but also effectively prevents cracks or deformation of the lamp housing caused by long-term wind impact, thereby extending the overall service life of the lamp. This solves the problem of traditional emergency lighting equipment being easily affected by wind interference in strong wind environments, leading to swaying, tipping, or even damage. Through structural optimization, the environmental adaptability of the equipment is enhanced, ensuring the continuity and safety of emergency repair operations, achieving the technical effects of improved wind resistance, improved lighting effect, and improved overall stability.

[0044] Example 2: Although the pointed end of the triangular section of the wind-resistant component 200 can point towards the wind direction under the action of the tail flag 250, its fixed geometry cannot cope with drastic changes in wind speed (such as gusts or turbulence), resulting in limitations in the performance of the fixed section structure under varying wind speeds. To avoid the problem of sudden changes in wind load caused by a single section shape, this application proposes the following technical solution to address the above-mentioned technical problems, specifically:

[0045] like Figures 2 to 4 As shown, the wind-resistant component 200 includes a first sleeve 210, a second sleeve 220, a hinge seat 230, a flapping plate 240, a tail flag 250, and an airbag 260.

[0046] The first sleeve 210 is mounted on the telescopic rod 121; the second sleeve 220 is rotatably connected to the outside of the first sleeve 210 via a bearing; the hinge seat 230 is fixed on the second sleeve 220; two flipping plates 240 are provided, arranged in a mirror image, and rotatably connected to the hinge seat 230 respectively, the two flipping plates 240 and the airbag 260 together form a transverse cross section of a triangular structure; the tail flag 250 is a triangular structure, placed vertically, and fixed to the second sleeve 220 via a connecting rod, opposite to the hinge seat 230; the airbag 260 is fixed to the second sleeve 220 via a connecting plate and is located between the two flipping plates 240.

[0047] The two flipping plates 240 are arc-shaped and connected by a windproof cloth 241, which is made of elastic nylon fiber. The connecting block 242 is made of flexible rubber and is connected to the flipping plates 240 by snap-fit, which can flexibly adapt to the expansion of the airbag 260 and drive the flipping plates 240 on both sides to rotate at an angle.

[0048] The airbag 260 is connected to an external air pump through a pipe. The airbag 260 has an elliptical cross-section. By inflating itself, the airbag 260 extends along its own long axis, thereby pushing the flipping plate 240 to rotate and changing the included angle between the two flipping plates 240.

[0049] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0050] This application, by more precisely adjusting the angle of the tip and the cross-sectional size of the wind-resistant component 200, can more effectively resist the action of wind, prevent the lighting component 120 from swaying or tipping due to uneven force, and further improve the stability and safety of the equipment; by expanding and contracting the airbag 260, the included angle between the two flipping plates 240 can be adjusted in real time, that is, the cross-sectional shape of the wind-resistant component 200 can be changed, so that the wind-resistant component 200 can dynamically optimize the cross-sectional shape according to the changes in wind speed and wind direction, thereby dynamically adjusting the wind resistance and avoiding the problem of sudden wind load caused by a single cross-sectional shape.

[0051] Under weak wind conditions, the wind-resistant component 200 can maintain an acute angle (low-drag streamline) to reduce wind resistance; under strong wind conditions, it unfolds into an obtuse angle to induce airflow separation in advance, reduce pressure, and enable the lighting equipment to better adapt to the needs of different wind environments. At the same time, by adjusting the included angle to change the size of the wake vortex, large vortices are broken into smaller vortices, accelerating the dissipation of turbulent kinetic energy and reducing structural vibration.

[0052] Example 3: Since the tilting plate 240, through a single-degree-of-freedom hinge, can only cope with wind loads in a single plane, it cannot adapt to three-dimensional wind fields (such as a combination of gusts and crosswinds), thus limiting its applicability. To address the aforementioned technical problems, this application proposes the following technical solution:

[0053] like Figures 4 to 7 As shown, both of the flipping plates 240 are rotatably connected to the hinge seat 230 via ball joints, and the side of each of the flipping plates 240 near the airbag 260 is connected to both sides of the top of the airbag 260 via connecting blocks 242.

[0054] The airbag 260 includes a plurality of vertically arranged small airbags 261. The volume of the multiple small airbags 261 in the fully inflated state increases sequentially from top to bottom, so that the airbag 260 forms a stepped inclined structure, which drives the flipping plates 240 on both sides to flip to both sides with the hinge point of the hinge seat 230 and the connecting block 242 as the axis, so that the flipping plates 240 are arranged at an incline.

[0055] This application utilizes a ball joint connection to allow the tilting plate 240 to adjust synchronously in both pitch (longitudinal) and yaw (lateral) directions, thereby adapting to three-dimensional wind fields, such as combinations of gusts and crosswinds, ensuring the lighting equipment remains stable even in complex wind environments. The inclined windward surface allows the airflow to accelerate along the curved surface, expanding the area of ​​the local negative pressure zone, thus reducing pressure drag, delaying laminar separation, and further reducing frictional resistance. Simultaneously, the stepped inclined structure formed by multiple small airbags 261, along with the inclined arrangement of the tilting plate 240, further optimizes the streamlined structure, helping to better disperse wind force, reduce wind resistance, and improve the equipment's wind resistance. Through more precise angle adjustment and optimized streamlined structure, this device can more effectively resist wind forces, preventing the equipment from swaying or tipping over due to excessive wind, thereby improving the equipment's stability and wind resistance.

[0056] Example 4: Considering that different emergency scenarios require lighting at different heights, and that the strength and direction of wind may change with height, especially in high-rise buildings or open areas, as the lighting lamps 122 rise, the tops of multiple lighting lamps 122 may sway in strong winds, resulting in poor lighting performance in strong winds. This application proposes the following technical solution to address the above-mentioned technical problems:

[0057] like Figure 2 and Figure 8As shown, each of the lighting components 120 is provided with a support rod 130 between it and the lighting platform 100. The support rod 130 is an elastic telescopic structure. Its fixed section is rotatably connected to the lighting platform 100 by a hinge, and its telescopic section is slidably connected to the telescopic rod 121 by a ring 160. The ring 160 is fixed to the telescopic rod 121 by a fixing bolt. It is used to fix the position of the support rod 130 according to the change of the height of the lighting lamp 122, and to support the lighting component 120 through the ring 160.

[0058] Multiple position holes 123 are evenly provided on the outer side of the fixed section of the telescopic rod 121 along its length.

[0059] Multiple wind-resistant components 200 are provided, each fixed to the position hole 123 at the corresponding height position by locking bolts 150. The multiple wind-resistant components 200 and the support rod 130 work together to provide multi-point support for the lighting component 120 as a whole, so as to ensure the overall stability of the lighting component 120.

[0060] This application sets up multiple support rods 130 and places them at an angle to pull and support the lighting components 120, which can effectively reduce the synchronous swaying of multiple lighting components 120 under the action of wind. The multi-point support method can disperse the effect of wind on individual lighting components 120, thereby improving the stability of the entire lighting system.

[0061] Multiple position holes 123 are evenly distributed along the length of the telescopic pole 121 on its outer side. Each wind-resistant component 200 has its sleeve 210 fixed to the corresponding position hole 123 by a locking bolt 150. This allows the wind-resistant component 200 to flexibly adjust its fixed position on the telescopic pole 121 according to the different lighting height requirements of the lighting lamp 122, thus achieving multi-point protection at different heights. Regardless of changes in wind force or direction, the wind-resistant component 200 can effectively protect the overall structure of the telescopic pole 121 and the lighting lamp 122 and resist wind force, protecting the lighting component 120 from damage. Through the cooperation of multiple sets of wind-resistant components 200 and the support pole 130, a multi-point support system for the lighting component 120 is formed, which not only enhances the overall stability of the lighting system but also significantly improves its wind resistance. In strong wind environments, the multi-point support system can more effectively disperse wind force, reducing the risk of swaying and damage to the lighting component 120.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
