A searchlight, which is a lighting device, has a powerful light source and a concave mirror capable of focusing light to project the light in a specific direction. Starting from birth, it is for remote illumination and searching. But is of a larger volume and weight than its powerful lighting capacity. For convenience of operation, most searchlight is provided with side support rods or movable carriers, and even large searchlight is provided with a special vehicle as a carrier.
Since the birth of searchlight, it has been widely used in national defense, military, judicial (prison, guard house, working and teaching house, work and improvement farm), water conservancy (sluice, reservoir, hydropower station, hydrologic station), electric power and other departments, and in large industrial and mining enterprises, large Cheng Shi industrial sites, oil fields, iron and steel works, airports, wharfs, offshore or field search and rescue sites. The wide application range corresponds to various searchlight lamp holders. In order to meet the working conditions of searchlight under different environments, the lamp bracket also derives various frameworks.
The marine searchlight is a device for lighting when a fishing boat runs at sea at night, and a lamp bracket for installing the searchlight needs to have the performance of resisting the bumping of the boat body because the boat body runs on the sea for a long time, for example, a side support rod is assembled at the periphery of the lamp bracket, so that the searchlight is prevented from being damaged due to the bumping of the boat body. However, in the running process of the fishing boat, the searchlight and the corresponding lamp bracket thereof are required to bear the force and moment generated by bumping from the boat body, and also the impact of wind resistance on the searchlight and the lamp bracket under different navigation conditions, because the bending moment resistance of the lamp bracket is limited, if the wind resistance reaches a certain preset value or even exceeds the preset value, the bending moment stress (shear stress) borne by the lamp bracket is very likely to exceed the allowable stress to cause the bending and breaking of the lamp bracket; besides, the lamp bracket is welded on the ship body generally due to the large volume, so that the application range of the lamp bracket is limited.
