Description
Technical field
The present invention relates to the measurement of physical parameter, the particularly sunray measuring method relative to the angle of inclination of level ground.
Background technology
The earth revolves around the sun owing to will enclose, the axis of the earth is tilt relative to revolution orbit place plane (ecliptic plane), along with the change of earth present position, the position of sunshine point of vertical is also changing, move between the tropic of north and south, the region outside the tropic of north and south, sunray is all oblique fire state forever, so the angle of earth horizontal surface and sunray is exactly the physical quantity of a dynamic change, so how to measure such parameter.
Summary of the invention
For measuring the angle of inclination of sunray relative to level ground, the present invention proposes a kind of measuring method.
The technical scheme that the present invention realizes goal of the invention employing is: the method measuring sunray relative level terrain slope angle, it is characterized in that: a detection disk, the center of detection disk is light intensity sensor, light intensity sensor is connected electrically to light intensity display device by call wire, detection disk and light intensity sensor are in same plane and have the common center of circle, and there is a spirit bubble at the edge of detection disk, the lower surface of detection disk has two grooves and a hinge, two grooves are rectangular parallelepiped cavity, the central axis of two grooves is mutually vertical, the intersection point of the central axis extended line of two grooves is the center of circle of detection lower disk surface, hinge is positioned on the extended line of one of them groove central axis, described groove and hinge are positioned at the both sides in the center of circle of detection lower disk surface, the top of iron square hinge another one pillar under the spherical top of a lower contact pillar of described groove and described hinge, the bottom of these two pillars is connected by connecting rod, two pillars and connecting rod form a door word frame, the pillar of the lower contact of described groove there is above-below direction regulating device, the spherical top of lower contact the 3rd pillar of another groove, the 3rd pillar has left and right directions regulating device, and the bottom of the 3rd pillar is connected to a center for word frame bottom connecting rod by connecting rod, first regulate above-below direction regulating device, the light intensity value that light intensity display device is shown is maximum, and then regulate left and right directions regulating device, the light intensity value that light intensity display device is shown is maximum, records light intensity value Q1 now, regulate above-below direction regulating device and left and right directions regulating device, observed by spirit bubble, make detection disk be in level, now record the light intensity value Q2 of light intensity display device, then Q2/Q1=cos
2θ, wherein θ is the angle of inclination on sunray relative level ground.
The invention has the beneficial effects as follows: solar irradiation is mapped to ground, the horizontal direction (tangential direction of earth surface) on ground, because earth surface is not a plane (partial sphere), there is height to rise and fall, thus the light intensity sensor needing spirit bubble to indicate detection disk to be embedded in whether be in horizontal direction; When the surface of light intensity sensor is vertical with sunray, the light intensity now detected is maximum, because 3 determine a plane, so two points at least should be regulated to change the orientation of plane, door type is presented owing to there being two pillars, after one of them pillar raises or reduces, the run-off the straight of detection disk, distance between two pillars of its lower surface contact must occur to become large, so realized by a groove, make the upper end of one of them pillar be arranged in groove, and can slide in the trench, its top is spherical, is conducive to reducing friction; The top of the 3rd pillar is arranged in another groove, and top is spherical, is conducive to reducing friction, the height of adjustable fixing, thus changes the orientation of detection disk; The bottom of pillar is connected by connecting rod, strengthens its stability; Structure is simple, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is device schematic diagram of the present invention.
Embodiment
Support is made up of three pillars, and wherein two pillars and bottom linkage rod form a door word frame, and the bottom linkage rod of another pillar is connected to a center for word frame bottom connecting rod, a detection disk is fixed at the top of support, the center of detection disk is light intensity sensor, light intensity sensor is connected electrically to light intensity display device by call wire, and detection disk and light intensity sensor are in same plane and have the common center of circle, and there is a spirit bubble at the edge of detection disk, the lower surface of detection disk has two grooves and a hinge, two grooves are rectangular parallelepiped cavity, the axis of two grooves is mutually vertical, the intersection point of the axis extended line of two grooves is the center of circle of detection lower disk surface, hinge is positioned on the extended line of one of them groove axis, described groove and hinge are positioned at the both sides in the center of circle of detection lower disk surface, one of them post top portion (sphere-contact of door word frame, reduce friction) be arranged in groove, can slide in the trench, described pillar has above-below direction regulating device, another pillar upper end of door word frame is connected to hinge, the top (sphere-contact reduces friction) of the remaining pillar of another trench contact (or being called the 3rd) below detection disk, pillar has left and right directions regulating device, first regulate above-below direction regulating device, the light intensity value that light intensity display device is shown is maximum, and then regulate left and right directions regulating device, the light intensity value that light intensity display device is shown is maximum, records light intensity value Q1 now, regulate above-below direction regulating device and left and right directions regulating device, observed by spirit bubble, make detection disk be in level, now record the light intensity value Q2 of light intensity display device, then Q2/Q1=cos
2θ, wherein θ is the angle of inclination on sunray relative level ground.
Sunshine direct projection is maximum to light vector during light intensity sensor, and when being mapped to light intensity sensor after sunshine cant angle theta angle, its light vector component is cos θ, and square being directly proportional of light intensity and light vector amplitude, therefore light intensity is changed to cos
2θ doubly.
