Description

Technical Field

[0001] This invention belongs to the technical field of power construction and emergency rescue equipment, and in particular relates to a lifting lighting device with emergency power supply function. Background Technology

[0002] Reliable lighting is essential for ensuring work quality and personnel safety during nighttime operations, including power grid construction, urban emergency repairs, flood and drought control, and various unforeseen incidents. Since these construction sites are typically located in the wild, remote mountainous areas, or regions damaged by natural disasters, they often lack mains power or have experienced power outages. Therefore, self-powered mobile lighting equipment is widely used. This equipment needs to be able to be quickly deployed to the work site, providing high-brightness, wide-area lighting coverage to meet the demands of nighttime operations under complex conditions.

[0003] However, existing traditional mobile lighting equipment primarily relies on fuel-powered generator sets (diesel or gasoline generators) as its power source in practical applications. While this internal combustion engine-based technology is mature, it has revealed significant technical shortcomings in the context of increasingly stringent modern power construction and environmental protection requirements. First, internal combustion engines generate high-decibel mechanical noise and vibration during operation, which not only severely interferes with command and dispatch and voice communication at the construction site, but also causes serious noise pollution problems, leading to construction complaints due to environmental noise, especially when used in tunnels, underground utility tunnels, or poorly ventilated confined spaces. Second, fuel-powered generators continuously emit exhaust gases, which do not meet current green construction and low-carbon environmental protection standards. Especially when used in tunnels, underground utility tunnels, or poorly ventilated confined spaces, the accumulation of exhaust gases poses a safety hazard to the respiratory health of workers. In addition, traditional lifting lighting structures mostly use hand-cranked winches or simple hydraulic push rods to drive the lamp post to rise and fall. The illumination angle (pitch and rotation) of the lamps usually needs to be fixed manually on the ground. Once the lamp post is raised to the high working position, the operator cannot make secondary fine adjustments to the direction of illumination according to the changes in the working surface, resulting in many blind spots and low deployment efficiency.

[0004] Therefore, how to completely eliminate the noise and exhaust pollution caused by internal combustion engine power generation while ensuring that mobile lighting equipment has sufficient battery life and light intensity, and at the same time solve the problems of inflexible adjustment of lighting height and angle, inability to achieve all-round precise coverage, and difficulty in adapting to the power supply needs of precision equipment, are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a lifting lighting device with emergency power supply function.

[0006] A lifting lighting device with emergency power supply function includes: A mobile cabinet assembly, comprising a housing and wheels mounted on the bottom of the housing; A power supply unit is located inside the enclosure and is used to store electrical energy and output alternating current. An automatic lifting mechanism is vertically installed inside the housing, its bottom end fixed to the bottom of the housing, and its top end passing through the top of the housing and extending to the outside; and A fully adjustable lighting assembly is installed at the top of the automatic lifting mechanism; The power supply unit is electrically connected to the automatic lifting mechanism and the omnidirectional adjustable lighting component, respectively. The power supply unit drives the automatic lifting mechanism to adjust the height and provides working power to the omnidirectional adjustable lighting component.

[0007] Furthermore, the power supply unit includes: A battery bracket is fixedly installed on one side of the interior of the housing. Energy storage battery modules are stacked and mounted on the battery bracket; and An inverter control unit is installed inside the enclosure and electrically connected to the energy storage battery module. The inverter control unit is equipped with a power output interface and a status display screen.

[0008] Furthermore, the automatic lifting mechanism includes: An air compression assembly is fixed inside the housing; and A multi-section telescopic pneumatic mast, the base of which is fixed to the center of the chassis of the box, and the mast sections are connected sequentially from bottom to top and can slide and extend relative to each other; The air output end of the air compression assembly is connected to the air inlet of the multi-section telescopic pneumatic mast via an air pipe.

[0009] Furthermore, the air compression assembly includes an air compressor and an air tank. The air compressor is installed above the air tank, and the air tank is fixed to the chassis of the housing. The air compressor is powered by the power supply unit.

[0010] Furthermore, the omnidirectional adjustable lighting assembly includes: An automatic rotating gimbal is fixedly installed on the top of the automatic lifting mechanism. The automatic rotating gimbal has a horizontal rotation axis and a pitch rotation axis. An illumination beam is connected to the output end of the automatic rotating gimbal; and Several LED lighting heads are symmetrically installed on both sides of the lighting beam.

[0011] Furthermore, the mobile cabinet assembly also includes a mast fixing flange, which is disposed on the top plate of the cabinet, and the automatic lifting mechanism passes through the mast fixing flange and is fastened to it by bolts; A sealing cover is provided on the top plate of the housing around the protrusion position of the automatic lifting mechanism.

[0012] Furthermore, several heat dissipation louvers are provided on the side wall of the enclosure corresponding to the positions of the inverter control unit and the energy storage battery module; an inspection door is provided on the other side wall of the enclosure, and the inspection door is equipped with an embedded door lock.

[0013] Furthermore, the casters are omnidirectional casters with brake locking devices; the outer side of the housing is also equipped with a control panel, which has control buttons for controlling the lifting of the automatic lifting mechanism and the switching of the omnidirectional adjustable lighting components.

[0014] The beneficial effects of this invention are: This invention provides a lifting lighting device with emergency power supply function. A power supply unit for storing electrical energy and outputting AC power is installed inside the mobile cabinet assembly, serving as the core power source to directly drive the automatic lifting mechanism and the omnidirectional adjustable lighting components. Because the use of electrical energy storage and output directly replaces the traditional fuel-powered internal combustion engine, the device eliminates the need for fuel combustion during operation, physically cutting off the source of exhaust emissions and high-decibel mechanical noise. This achieves zero emissions and ultra-quiet operation, significantly improving the environmental protection level and work comfort at construction sites, making it perfectly adaptable to special scenarios with strict environmental restrictions, such as tunnels, confined spaces, and residential areas. Simultaneously, thanks to the power supply unit's electrical drive control of the automatic lifting mechanism and the omnidirectional adjustable lighting components, the device can achieve automated vertical adjustment of the lighting height and flexible multi-dimensional changes in the lighting angle. This electromechanical integrated linkage control structure allows the lighting beam to accurately and quickly cover the target work area, effectively avoiding the lag of manual adjustment and the safety risks of high-altitude operations, greatly improving the efficiency of lighting deployment. In addition, the combination of the mobile cabinet components and the bottom casters not only achieves a high degree of integration and physical protection of the power supply and lighting systems, but also gives the device high mobility for rapid response and flexible relocation in emergency rescue scenarios, ensuring the timeliness and reliability of power supply and lighting support.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the present application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0018] In the following description, references to "some embodiments" refer to a subset of all possible embodiments; however, it is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. Unless otherwise defined, all technical and scientific terms used in the embodiments of the invention have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of the invention pertain. The terminology used in the embodiments of the invention is for the purpose of describing the embodiments of the invention only and is not intended to limit the invention.

[0019] Those skilled in the art should understand that, in the following description of the embodiments of the present invention, the sequence of numbers does not imply the order of execution. Some or all steps may be executed in parallel or sequentially. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0020] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a lifting lighting device 100 with emergency power supply function. This lifting lighting device 100 is an electromechanical composite system integrating mobile energy storage, automatic lifting, and omnidirectional high-intensity lighting functions. It is mainly used in scenarios requiring independent power supply and wide-area lighting, such as power repair, field construction, emergency rescue, and large-scale event support. From an overall architectural perspective, the lifting lighting device 100 mainly consists of a mobile cabinet assembly 110 as the basic support carrier, a power supply unit 120 as the core energy center, an automatic lifting mechanism 130 as the height adjustment actuator, and an omnidirectional adjustable lighting assembly 140 located at the top to perform lighting tasks. These four core parts form a compact, stable, and functionally coordinated organic whole through mechanical, electrical, and pneumatic connections.

[0022] The mobile cabinet assembly 110 serves as the physical foundation and protective shell for the entire lifting lighting device 100, with its core component being the housing 111. The housing 111 is a rectangular hexahedral structure manufactured from high-strength cold-rolled steel plate through laser cutting, CNC bending, and welding. Its surface undergoes pickling, phosphating, and electrostatic powder coating treatment, providing excellent rust resistance, corrosion resistance, and UV resistance, enabling it to withstand harsh outdoor operating environments such as humidity and salt spray. The wall thickness design of the housing 111 fully considers the load-bearing requirements of the internal load, ensuring that the housing structure does not deform when fully loaded with the energy storage battery module 122 and under the dynamic load generated by the lifting of the pneumatic mast 132. To facilitate convenient movement and rapid deployment of the device, casters 112 are securely installed at the four corners of the chassis at the bottom of the housing 111. These casters 112 are industrial-grade heavy-duty swivel casters, preferably made of wear-resistant polyurethane or high-strength nylon, and integrate double ball bearings to reduce rolling friction resistance, allowing a single person to push the entire device on a flat surface. More importantly, the mobile wheel 112 is equipped with a dual brake locking device. When the locking device is pressed, it can lock the rolling direction and the omnidirectional rotation direction of the wheel at the same time, ensuring that the device can be stably parked after arriving at the designated construction site. This prevents the device from being accidentally displaced due to ground slope or wind load after the mast is raised, thus ensuring operational safety.

[0023] At the center of the top plate of the enclosure 111, there is a dedicated outlet for installing and fixing the automatic lifting mechanism 130. A mast fixing flange 113 is also installed at this location. The mast fixing flange 113 is securely connected to the top plate frame of the enclosure 111 using high-strength bolts. Its inner hole precisely matches the outer diameter of the multi-section telescopic pneumatic mast 132, serving not only as a radial limit to prevent the mast from swaying when raised, but also dispersing the bending moment load transmitted by the mast through the flange structure. To prevent rainwater, sand, and other foreign objects from entering the enclosure 111 through the mast outlet, a sealing cover is also installed on the top plate of the enclosure 111 around the outlet of the automatic lifting mechanism 130. This cover typically uses an aging-resistant rubber bellows or a multi-layer sealing ring structure, tightly fitting against the base of the mast to ensure that the enclosure 111 as a whole meets an IP54 or higher protection rating.

[0024] To facilitate routine inspection, maintenance, and replacement of the electrical equipment and pneumatic components inside the enclosure 111, a maintenance door 114 is hinged to one side wall of the enclosure 111. A continuous EPDM sealing strip is affixed to the inner edge of the maintenance door 114, which is pressed shut when the door is closed to prevent external moisture. An embedded lock is also installed on the maintenance door 114; this lock preferably uses a flat-press type spring-loaded lock, ensuring a smooth and aesthetically pleasing surface, preventing scratches during transportation, and ensuring that unauthorized personnel cannot access the internal high-voltage electrical equipment. Considering that the inverter control unit 123 and the energy storage battery module 122 in the power supply unit 120 will generate heat during charging and discharging, several ventilation louvers 115 are provided on the side wall of the enclosure 111, specifically corresponding to the internal heat sources. The 115 heat dissipation louvers adopt a stamped downward opening structure. This "gill-like" design guides the internal hot airflow through natural convection or forced air cooling and discharges it, while effectively preventing external rainwater from flowing back into the cabinet along the wall, thus achieving a balance between heat dissipation and waterproofing.

[0025] like Figure 4The vertical cross-sectional view shown indicates that the power supply unit 120 is the energy source for the entire device. Unlike traditional fuel generators, this device achieves zero emissions and low noise. The power supply unit 120 mainly includes a battery bracket 121, energy storage battery modules 122, and an integrated inverter control unit 123. The battery bracket 121 is fixedly installed on one side inside the housing 111, using a frame structure welded from angle steel or square tubing, and rigidly connected to the base and side walls of the housing 111 by bolts to support the heavy weight of the battery pack. The energy storage battery modules 122 are stacked in the various compartments of the battery bracket 121. This stacked layout not only makes full use of the longitudinal space of the housing 111, making the device more compact, but also effectively lowers the center of gravity of the entire unit, improving its anti-tipping ability. The energy storage battery modules 122 preferably use lithium iron phosphate battery packs, which are very suitable for use as a mobile power source due to their high thermal stability, long cycle life, and good safety. The battery packs are connected in series and parallel via busbars to output DC power that meets the system voltage requirements (e.g., 48V or 72V).

[0026] Located beside or above the battery bracket 121 is the inverter control unit 123, which is electrically connected to the energy storage battery module 122 via a high-current cable. The inverter control unit 123 integrates the functions of a battery management system, an MPPT charging controller, and a DC-AC inverter. Its core function is to convert the DC power output from the energy storage battery module 122 into pure sine wave AC power (e.g., 220V / 50Hz) to drive internal AC loads (such as the air compressor 1311) and external loads. The panel of the inverter control unit 123 is directly embedded in or mounted on the inner wall of the enclosure 111, exposing the operating interface through openings, or connected to an external control panel via an extension cable. The inverter control unit 123 has a power output interface 1231, which is typically configured as an industrial-grade waterproof socket with a spring cover, providing stable power support for power tools such as electric drills, cutting machines, and welding machines on the construction site, enabling the device to serve multiple purposes. Meanwhile, the inverter control unit 123 is also equipped with a status display screen 1232. The display screen uses an LCD screen or a high-brightness LED digital tube to display key information such as the current battery power, output voltage, load power, remaining running time and fault codes in real time, so that operators can intuitively grasp the system operating status.

[0027] The automatic lifting mechanism 130, vertically mounted at the center of the housing 111, is a key component for adjusting the lighting height. The automatic lifting mechanism 130 consists of an air compression assembly 131 as the power source and a multi-section telescopic pneumatic mast 132 as the actuator. The base of the multi-section telescopic pneumatic mast 132 is fixed to the center of the reinforcing ribs of the housing 111 chassis with high-strength bolts, ensuring uniform force distribution. The mast is constructed from multiple sections of aluminum alloy round or shaped tubes with progressively decreasing diameters, with precision guide bushings and airtight seals between adjacent sections. The aluminum alloy surface undergoes hard anodizing, resulting in extremely high surface hardness and wear resistance. When the internal air pressure increases, each section extends sequentially from bottom to top under the pressure; when the air pressure is released, the mast retracts under its own weight and external gravity. To prevent unintended horizontal rotation of the lighting fixture during lifting, anti-rotation keyways are typically provided between the mast sections.

[0028] The air supply for the multi-section telescopic pneumatic mast 132 is provided by an air compression assembly 131 fixed inside the housing 111. This air compression assembly 131 includes an air compressor 1311 and an air tank 1312. The air tank 1312 is horizontally fixed to the chassis of the housing 111, located opposite the battery bracket 121, serving to balance the overall weight distribution. The air compressor 1311 is mounted on a mounting base above the air tank 1312, and the two are connected by a metal hose or high-pressure air pipe. The air compressor 1311 is driven by electricity provided by the power supply unit 120, and preferably uses an oil-free silent reciprocating compressor to maintain the quiet operation of the device at night. The high-pressure gas generated by the air compressor 1311 first enters the air tank 1312 for pressure stabilization and gas-liquid separation. The air tank 1312 not only eliminates airflow pulsations, making mast raising and lowering more stable, but also maintains system pressure after the compressor stops working. The air output end of the air compression assembly 131 is connected to the air inlet at the bottom of the multi-section telescopic pneumatic mast 132 via a high-pressure resistant PU tube or nylon tube. The air circuit system also includes a solenoid valve (or manual reversing valve), a check valve, and a speed regulating throttle valve connected in series. By controlling the on / off state and flow direction of the solenoid valve, the raising, stopping, and lowering actions of the mast can be precisely controlled.

[0029] Mounted atop the automatic lifting mechanism 130 is an omnidirectional adjustable lighting assembly 140. A mounting flange is fixed to the top of the multi-section telescopic pneumatic mast 132, and the base of the omnidirectional adjustable lighting assembly 140 is rigidly connected to it. The core of this assembly is an automatic rotating pan-tilt head 141, an electromechanical actuator with dual-axis degrees of freedom, containing a horizontal rotation motor and a pitch rotation motor, driven by a worm gear or gear reduction mechanism. The automatic rotating pan-tilt head 141 has a horizontal rotation axis and a pitch rotation axis, enabling 360-degree unlimited horizontal rotation and more than 90 degrees of vertical pitch adjustment. A conductive slip ring is integrated inside the pan-tilt head to ensure that the power cord and control signal line will not become tangled or broken during unlimited rotation. Connected to the output end of the automatic rotating pan-tilt head 141 is a lighting beam 142, made of lightweight, high-strength aluminum alloy profile, in a straight or T-shaped structure. Several LED lighting heads 143 (four shown in the illustration) are symmetrically mounted on both sides of the lighting beam 142. The LED lighting head 143 uses high-efficiency LED modules as its light source, with a color temperature typically selected to be close to sunlight (5000K-6500K). It boasts a high color rendering index, accurately reproducing the colors of objects at the construction site. The head housing is made of die-cast aluminum alloy, with dense heat dissipation fins on the back and a tempered glass lens covering the front. The lens's optical design can be configured as either a focused (long-range) or floodlight (large-area coverage) type, depending on requirements. The power supply unit 120 supplies power to the automatic rotating pan / tilt head 141 and the LED lighting head 143 via a spiral cable that passes through the inside of the mast or spirally winds around its exterior.

[0030] In terms of control logic, the external side of the enclosure 111 features an integrated control panel (not shown separately in detail in the figure, but a standard configuration in this field). The control panel is electrically connected to the inverter control unit 123 and various actuators. The panel includes "Up," "Down," and "Stop" buttons for controlling the lifting action of the automatic lifting mechanism 130, as well as "Light On / Off" and "Brightness Adjustment" knobs for controlling the omnidirectional adjustable lighting component 140, and directional joysticks or buttons for controlling the "Up, Down, Left, Right" movement of the automatic rotating pan-tilt unit 141. Operators can complete the entire process from mast raising and light activation to fine-tuning the illumination angle without climbing, simply by standing on the ground and using the control panel. Furthermore, the system incorporates safety interlocking logic, such as issuing an alarm when the caster 112 is not locked, or prohibiting long-distance towing when the mast is not fully lowered, to maximize equipment and personnel safety. Through the close cooperation of the aforementioned components, the entire device perfectly solves the problems of high noise, heavy pollution, and difficult adjustment associated with traditional fuel-fired lighthouses, providing a green, intelligent, and efficient nighttime construction lighting solution.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
