Construction site all-directional illumination projection lamp

Abstract

The invention discloses an omnidirectional lighting projection lamp for construction sites. The front end is provided with a searchlight head, and the left and right sides of the projection lamp assembly are respectively provided with a first rotating shaft and a second rotating shaft. A third conical wheel fixedly connected with the first rotating shaft is arranged in the groove, a second sliding block is rotatably connected to the right end of the second rotating shaft, and the tops of the inner walls of the left and right sides of the groove are symmetrically provided with installation grooves, and the left installation groove A first cavity is provided in the mounting frame on the side away from the groove, a second cavity is provided in the mounting frame below the first cavity, and a third cavity is provided in the mounting frame on the right side of the second cavity. The three cavities are provided with spline drive rods extending left and right, and the right end of the spline drive rod is powered with the first motor.

Description

technical field [0001] The invention relates to the technical field of projection lamps, in particular to an all-round lighting projection lamp for a construction site. Background technique [0002] Projector lights are commonly used lighting equipment on construction sites, and their proper arrangement directly affects the construction at night and in dark environments. At present, the traditional way is to use fixed searchlights to solve lighting problems. Ways are adopted: frame body fixing, rod body fixing, fixing on the ground by means of structure fixing, etc. When solving multi-directional lighting in different time periods, it is usually solved by reinstalling the searchlight orientation or increasing the number of searchlights, which is very inconvenient in actual use and requires a lot of investment, or directly fix related facilities such as projection lights and switch boxes at will. A certain fixed point on the site, and the operation of the free rotation of th...

Problems solved by technology

When solving multi-directional lighting in different time periods, it is usually solved by reinstalling the searchlight orientation or increasing the number of searchlights, which is very inconvenient in actual use and requires a lot of investment, or directly fix related facilities such as projection lights and switch boxes at will. A certain fixed point on the site, and the operation of the free rotation of the projection lamp is extremely cumbersome, which affects the efficiency of on-site construction; moreover, the projection lamp in the prior art has a fixed lighting angle and has a large dead angle, which cannot realize omnidirectional lighting, and the work efficiency is low.
