Description

Technical Field

[0002] As an important emergency rescue equipment, portable emergency lighting was mainly used in building fire fighting, power repair, outdoor adventure and other scenes in the early days. Its core technology revolves around high-brightness light sources (such as LEDs), rechargeable battery systems and portable structural design. As emergency lighting scenes expand to extreme environments such as mines, tunnels, and marine rescue, the equipment needs to operate stably under the following conditions: high dust environment (such as the concentration of suspended particulate matter in the air after mine blasting> 10 mg / m³); high humidity and fog (such as humidity> 90% in coastal areas or condensation caused by temperature difference); dynamic temperature and pressure changes (such as pressure fluctuations caused by the start and stop of the ventilation system in the tunnel).

[0003] Traditional designs focus on lightweight, long battery life and fast response, but they generally have the following limitations: Inadequate environmental adaptability: In complex environments such as dust, humidity, rain and fog, insufficient sealing of the lamp body can easily lead to short circuits in the internal circuits and dust accumulation in the optical components, reducing lighting efficiency. High maintenance costs: Frequent cleaning of filters or removal of the outer shell for dust removal is complicated, affecting equipment reliability and user experience.

[0027] The avoidance track 7 includes an avoidance section 71 and two limit sections 72. The two limit sections 72 are respectively arranged at the two ends of the avoidance section 71, and the limit sections 72 and the avoidance section 71 are smoothly arranged; when the cleaning arm 5 located inside the avoidance track 7 moves along the avoidance section 71, it can make way for the moving path of the other cleaning arm 5 along the limit track 6 to avoid interference between the movement paths of the two cleaning arms 5; when the cleaning arm 5 located inside the avoidance track 7 moves along the limit section 72, the cleaning arm 5 can move close to the transparent protective cover 2; when the cleaning arm 5 located inside the limit track 6 moves along the limit track 6, the cleaning arm 5 can always move close to the transparent protective cover 2.

The movable end of the telescopic connecting rod 52 is fixed to one end of the arc-shaped mounting rod 51. The arc center of the arc-shaped mounting rod 51 coincides with the spherical center of the transparent protective cover 2. Bristles are arranged on the arc-shaped mounting rod 51, and the bristles are tightly attached to the transparent protective cover 2. When the arc-shaped mounting rod 51 is driven to be tightly attached to the transparent protective cover 2, the bristles arranged on the arc-shaped mounting rod 51 can clean the transparent protective cover 2.

A portable emergency lighting lamp according to claim 6, characterized in that: The cleaning drive assembly comprises a cleaning drive motor and a coaxial reversing unit, wherein the coaxial reversing unit comprises a fixed shaft, a reversing drive gear and two rotating sleeve shafts, and the ends of the rotating sleeve shafts close to the reversing drive gears are each provided with end face teeth; The two rotating sleeve shafts are both sleeved on the outside of the fixed shaft, and the two rotating sleeve shafts are respectively meshed with the reversing drive gear through the end face teeth, and the cleaning drive motor is power-connected with the reversing drive gear; The fixed ends of the telescopic connecting rods of the two cleaning arms are fixedly connected to the two rotating sleeve shafts respectively, and a limiting block is also arranged on one side of the telescopic connecting rod, and the limiting block can be respectively embedded in the limiting track and the avoidance track.

8. A portable emergency lighting lamp according to claim 7, characterized in that: The circumferential rotation unit comprises a circumferential support frame, a circumferential drive gear ring and a circumferential drive motor, wherein the circumferential drive motor is fixed on one side of the circumferential support frame; The radial mounting frame is arranged at the top end of the circumferential support frame, the circumferential drive gear ring is fixed between the radial mounting frame, a plurality of limit gears and circumferential drive gears are rotatably arranged on the circumferential support frame, and the limit gears and the circumferential drive gears are respectively meshed with the gears between the circumferential drive gear rings; The circumferential drive motor is power-connected to the circumferential drive gear. The circumferential drive motor can drive the radial mounting frame to rotate circumferentially under the support of the circumferential support frame through the gear meshing between the circumferential drive gear and the circumferential drive gear ring.

9. A portable emergency lighting lamp according to claim 8, characterized in that: The connecting ring comprises a rotating connecting ring and a driven internal gear ring, the limiting gear and the circumferential driving gear both pass through the accommodating cavity, and the limiting gear and the circumferential driving gear are respectively meshed with the driven internal gear ring; The rotating connecting ring is fixed to the driven inner gear ring, and the limiting track and the avoiding track are both fixed to the rotating connecting ring; The driven inner gear ring can rotate synchronously with the radial mounting frame in the circumferential direction, and at the same time, drive the limiting track and the avoidance track to rotate synchronously in the circumferential direction.

10. A method for using a portable emergency lighting, characterized in that: A portable emergency lighting device as claimed in any one of claims 1 to 9 is used, comprising the following steps: A portable emergency lighting fixture is fixed to a selected lighting location by means of a mounting base; The radial rotation unit drives the lighting assembly to rotate radially, and the circumferential rotation unit indirectly drives the lighting assembly to rotate circumferentially by driving the radial rotation unit, thereby changing the lighting position of the linear light source generated by the lighting assembly.
