Construction site all-directional illumination projection lamp

Abstract

The invention discloses a construction site all-directional illumination projection lamp. The lamp comprises a mounting frame body provided with a groove in the top, and a mounting base rotationally matched and connected with the bottom of the mounting frame body; a projection lamp module is arranged in the groove; a searchlight cap is arranged on the front end surface of the projection lamp module; a first rotating shaft and a second rotating shaft are respectively arranged on the left and right sides of the projection lamp module; the tail end of the left side of the first rotating shaft is rotationally matched and connected with a first slide block; an opening groove is formed in the first slide block; a third conical wheel fixedly connected with the first rotating shaft is arranged in the opening groove; the tail end of the right side of the second rotating shaft is rotationally matched and connected with a second slide block; mounting grooves are symmetrically formed in the tops of the inner walls of the left and right sides of the groove; a first cavity is formed in the mounting frame body on one side, far from the grove, of the mounting groove on the left side; a second cavity is formed in the mounting frame body below the first cavity; a third cavity is formed in the mounting frame body on the right side of the second cavity; a spline driving rod extending left and right is arranged in the third cavity; and the right side end of the spline driving rod is in power connection with a 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.
