Description

Technical Field

[0001] The utility model relates to the technical field of photometers, and more particularly to a compact portable photometer. Background Art

[0002] With the advancement of science and technology and the continuous improvement of living standards, people's demands for their living environment have also increased. The chemical composition of atmospheric aerosols is complex, significantly impacting climate change and human health. Photometers, a key instrument for measuring and monitoring atmospheric aerosols, are primarily used to measure the visible and near-infrared radiance of the sun, moon, and sky at different times and wavelengths.

[0003] Before the initial installation and fixation of existing photometers, precise north pointing operations and horizontal leveling of the equipment mounting base are generally required. In addition, the optical probe must be aligned during the initial installation and operation, that is, the initial azimuth position of the equipment and the initial pitch position of the optical probe need to be adjusted. In particular, the adjustment of the initial alignment position of the optical probe needs to be made during daytime and in good weather conditions, so that the position of the light spot formed by sunlight passing through the alignment hole can be clearly identified.

[0004] Currently, most of the connecting cables of photometers are installed externally. As a result, the connecting cables between the optical probe, control electrical box, and two-dimensional pointing turntable are in a dynamic stretching or bending state during the operation of the equipment, which is prone to failure. At the same time, the connecting cables are exposed to the external environment of the equipment and are prone to aging, which has a serious impact on the service life of the equipment and the continuity of measurement data. In view of this, we propose a compact portable photometer. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a compact portable photometer to solve the technical problem that most of the connecting cables of the current existing photometers are arranged externally, and the cables are easily stretched and bent during the operation of the equipment, causing malfunctions.

[0006] In order to solve the above technical problems, the present utility model provides the following technical solutions: a compact portable photometer, comprising a two-dimensional turntable with a fixing member rotatably provided on one side;

[0007] A pitch direction rotation axis is rotatably mounted in the center of one side of the two-dimensional turntable, a pitch direction conductive slip ring is rotatably mounted at the center of the end of the pitch direction rotation axis, a fixing piece is provided on the outside of the pitch direction conductive slip ring, and a cable socket is provided at the bottom of the fixing piece;

[0008] The bottom of the two-dimensional turntable is rotatably connected to a base, and an azimuth conductive slip ring is arranged inside the two-dimensional turntable. A three-axis electronic gyroscope is fixedly arranged on one side of the interior of the two-dimensional turntable. Internal cables are connected between the cable socket, the pitch direction conductive slip ring, the azimuth direction conductive slip ring and the three-axis electronic gyroscope.

[0009] The utility model designs a conductive slip ring in the pitch direction and a conductive slip ring in the azimuth direction. The pitch direction rotation axis has no mechanical limit and can realize continuous multiple-turn rotation. When rotating, the fixing part, the optical probe, the cable socket and the cable body are driven to rotate as a whole. The fixing part, the optical probe, the cable socket and the cable body remain relatively stationary, thereby avoiding the situation where the cable is in a dynamic stretching or bending state during the operation of the equipment. Moreover, since the internal cable is arranged inside, it is avoided that it is exposed to the external environment of the equipment for a long time and causes aging.

[0010] Preferably, the end of the pitch direction rotation axis away from the two-dimensional turntable extends into the interior of the fixing member and is coaxially fixedly connected to the fixing member, and the pitch direction conductive slip ring is arranged inside the fixing member.

[0011] Preferably, a triangular support frame is provided at the bottom of the base, and the base and the triangular support frame are detachably connected.

[0012] Preferably, a fixed shaft is centrally provided on one side of the fixing member, an optical probe is fixedly connected to one end of the fixed shaft away from the fixing member, and a cable body is connected between the optical probe and the cable socket.

[0013] Preferably, an azimuth rotation shaft is fixedly provided on the top of the base, and the azimuth conductive slip ring is installed at the end axis position of the azimuth rotation shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model designs a conductive slip ring in the pitch direction and a conductive slip ring in the azimuth direction. The pitch direction rotation axis has no mechanical limit and can realize continuous multiple-turn rotation. When rotating, the fixing part, the optical probe, the cable socket and the cable body are driven to rotate as a whole. The fixing part, the optical probe, the cable socket and the cable body remain relatively stationary, thereby avoiding the situation where the cable is in a dynamic stretching or bending state during the operation of the equipment. Moreover, since the internal cable is arranged inside, it is avoided that it is exposed to the external environment of the equipment for a long time to cause aging, and solves the problem that most of the connecting cables of the existing photometer are arranged outside, and the cables are easily stretched and bent during the operation of the equipment to cause malfunction.
