Ultraviolet radiation illuminometer capable of measuring underwater light intensity

The invention discloses an ultraviolet radiation illuminometer capable of measuring underwater light intensity, belongs to the technical field of illuminometers, and aims to solve the problem that the detection data of a traditional illuminometer is not accurate enough because the position of a probe is inconvenient to coincide with an underwater position to be detected by the traditional illuminometer. According to the folding mechanism, a connecting line segment is taken, the connecting line segment is located in the folding mechanism through the position of an annular connecting piece, the connecting line segment is limited by multiple sets of first limiting assemblies and second limiting assemblies, and a third folding strip can rotate with one end of a second folding strip as the circle center; the second folding strip can rotate by taking one end of the first folding strip as the circle center, that is, the detection position of the photosensitive probe is changed by rotating and folding the first foldi
