Mirror surface perpendicularity inspection method of marine sextant additionally provided with alignment module

Abstract

The invention discloses a mirror surface perpendicularity inspection method for a navigation sextant additionally provided with an alignment module, and belongs to the technical field of navigation equipment.The navigation sextant comprises a navigation sextant body and a fixing shaft, the fixing shaft is fixedly installed at the top of the navigation sextant body, and a gradienter perpendicular instrument is arranged on the inner side of the fixing shaft; and the gradienter verticality instrument is used for checking the verticality of the angle of the mirror surface. By combining the vertical connecting column, the gradienter vertical instrument, the instrument opening and closing cover, the handheld grip, the center connecting cylinder, the movable shaft, the angle scale ring, the connecting rectangular column and the gravity orthocenter, the problem that when an existing ship travels on the sea, the ship is prone to being impacted by sea surface waves, and consequently a navigation sextant cannot keep vertical balance is conveniently solved; therefore, when a ship travels on the sea, the mirror surface angle perpendicularity can be checked through the device, the device is prevented from being impacted by sea surface waves, the perpendicularity cannot be found, and the practical effect of the marine sextant is improved.

Description

technical field [0001] The invention relates to the technical field of navigation equipment, in particular to a method for inspecting the perpendicularity of a mirror surface with an alignment module added to a navigation sextant. Background technique [0002] A sextant is an optical instrument that can measure the angle between two distant targets. The most commonly used is to measure the angle between a celestial body and the sea (horizon) or between a celestial body and a celestial body. The latitude of the observer can be determined by measuring the included angle and checking the latitude of the point where the sun directly shines on that day. This has great implications for sailing. The sextant has been an important positioning and navigation tool since its introduction in the 18th century. This is an extremely simplified how-to. In actual use, there must be calibration and adjustment steps, and it is also necessary to ensure that the sextant is perpendicular to the...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a mirror verticality inspection method for adding an alignment module to a marine sextant, wherein the purpose is to have a vertical connecting column, a spirit level plumb, an instrument opening and closing cover, a hand-held grip, and a central connecting cylinder , active axis, angle scale ring, connecting rectangular column, and gravitational orthocenter, to solve the problem that existing ships are easily impacted by sea waves when they are driving on the sea, which leads to the problem that the nautical sextant cannot maintain vertical balance, so as to make the ship travel on the sea When using the device, the mirror angle can be checked vertically to prevent the device from finding the vertical angle due to the impact of sea waves, and to improve the practical effect of the nautical sextant
