Description

Technical Field

[0001] The utility model relates to the field of solar reflectance measuring instruments, in particular to a solar reflectance measuring instrument applicable to different building surfaces. Background Art

[0002] The main function of a solar reflectance measuring instrument is to measure the reflectance of materials, which belongs to the category of optical instruments and is specifically applied to academic fields such as mechanical engineering, optical instruments, and optical testing instruments. This kind of instrument can measure and record the ability of the material surface to reflect light, thereby evaluating the reflection characteristics of the material. The reflectance measuring instrument evaluates the reflection performance of the material by measuring the ratio of the intensity of the reflected light to the intensity of the incident light, that is, the reflectance.

[0003] When in use, the solar reflectance measuring instrument tests the test sample through the measuring head in the instrument. Among them, the measuring head includes a tungsten halogen lamp as a radiation source, a filter for adjusting the wavelength range of the reflected radiation, and a detector for measuring four wavelength ranges. A circular opening with a diameter of 2.5 cm at the top of the measuring head serves as a channel through which the incident and reflected radiation is transmitted to and from the test surface.

[0004] Currently, during the measurement, the staff needs to place the test sample on the circular opening at the top of the measuring head. Since there is a circular opening with a diameter of 2.5 cm left at the top of the measuring head, the size of the test sample must be larger than the circular opening in order to be placed on the circular opening. As shown in the attachment Figure 1 This is not suitable for measuring small-sized materials and has limitations in use. Therefore, a solar reflectance measuring instrument applicable to different building surfaces is designed to solve the above problems. Summary of the Utility Model

[0005] According to the above existing technical problems, the utility model provides a solar reflectance measuring instrument applicable to different building surfaces for measuring building materials of different sizes.

[0006] To achieve the above object, the technical solution of the utility model is as follows:

[0007] A solar reflectance measuring instrument applicable to different building surfaces, characterized by comprising a machine shell, a measuring main body, a limit clamping block, and a positioning component. An opening and closing cover is installed at the test port provided on the machine shell. The measuring main body is installed inside the machine shell. A test head is provided on the measuring main body. A limit clamping block is fixed at a position above the measuring main body on the inner wall of the machine shell. The limit clamping block is connected to the positioning component.

[0008] The positioning component is composed of a positioning frame, a positioning plate, a bidirectional lead screw, and an adjusting knob. One end of the positioning frame is installed with the bidirectional lead screw through a bearing. Both ends of the bidirectional lead screw are respectively threadedly connected to moving blocks. The moving blocks pass through the through slots provided on the positioning frame and are connected to the positioning plate. One end of the bidirectional lead screw is connected to the adjusting knob.

[0009] One end of the positioning plate is slidably connected in the chute provided on the positioning frame.

[0010] One end of the positioning frame is inserted into the limiting slot provided on the limiting block, and a support column is provided below the other end of the positioning frame.

[0011] Specifically, the threads on both sides of the bidirectional lead screw are in opposite directions.

[0012] Specifically, the positioning frame is located above the test head.

[0013] The beneficial effects of the present utility model:

[0014] The present utility model installs a positioning component above the test head of the measurement main body installed in the machine shell. When it is necessary to test the reflected light ability of building materials with different sizes on the surface, the operator places the sample to be tested between the two positioning plates, and then controls the two positioning plates to move towards each other by operating the adjusting knob to complete the positioning of the sample to be tested, increasing the test use range of the instrument. And after the sample to be tested is positioned by the positioning component, compared with directly placing it on the test head at present, it will not deviate in any way during the test process;

[0015] One end of the positioning frame in the positioning component is inserted into the limiting block, and the other end is supported by the support column. It is installed in the machine shell in a detachable manner, which is convenient for the disassembly and installation of the positioning component. Description of the drawings
