The upper end of the bracket 1 is provided with a mounting plate 2, and at least one mounting hole 8 is opened on the mounting plate 2. The mounting hole 8 is provided with a light source assembly 3. The outer walls of both sides of the light source assembly 3 are connected to the inner wall of the mounting hole 8 through the rotating shaft 4. The interior of the mounting plate 2 is provided with a motor 7, and the output end of the motor 7 is connected to one of the rotating shafts 4. A light sensor 6 is provided on one side of the mounting plate 2, and the motor 7 and the light sensor 6 are respectively connected to the processor 5. In this embodiment, the processor 5 is a PLC processor, which is used to be set on the river bank, and the specific setting position can be selected according to needs. Among them, the light sensor 6 is a sensor for underwater use, which has waterproof performance and is used to detect the visibility of light in the water body, and send the detected information to the processor 5 for processing, so that the light source intensity of the light source assembly 3 can change with the change of the light visibility in the water body. For example, as the depth of the water body increases, the light visibility will decrease. At this time, the light source intensity of the light source assembly 3 will increase, which is used to provide stronger illumination, so as to meet the photosynthesis needs of aquatic plants. Among them, the bracket 1 is arranged in an H shape, which is convenient for supporting. When the bracket 1 is sunk in the water body, the bottom of the bracket 1 will contact the riverbed, or the bracket 1 can be suspended at a specified depth in the water body as needed. A lifting ear 14 is provided at the upper end of the mounting plate 2, which is convenient for carrying the bracket 1, and can cooperate with an external hanging rope to sink the bracket 1 into the water body. The depth of the bracket 1 sunk into the water body is judged according to the length of the hanging rope sunk into the water body.

[0030] The motor 7 is used to drive the rotating shaft 4 to rotate, and the rotating shaft 4 will further drive the light source assembly 3 to rotate, so as to automatically adjust the irradiation angle of the light source assembly 3 as needed, and the motor 7 can be directly controlled to start and stop by the processor 5. The processor 5 can be wirelessly connected to an external smart device (mobile phone or computer), and a control signal can be sent to the processor 5 through the smart device to control the light source assembly 3 and the motor 7.

[0032] When in use, the bracket 1 is directly sunk into the water body or artificially sunk into the water body by connecting the hanging rope with the hanging ear 14, for example, the staff dives into the water and places the bracket 1 at a designated position. As the depth of the bracket 1 sinking into the water body is different, the visibility of the light detected by the light sensor 6 is also different. At this time, the processor 5 will also control the intensity of the light emitted by the light source assembly 3 to meet the photosynthesis needs of aquatic plants. During use, the processor 5 can control the motor 7 to work as needed through the motor 7, so that the motor 7 drives the light source assembly 3 to rotate. After the light source assembly 3 rotates a certain angle, the motor 7 can stop working. Of course, in other embodiments, the motor 7 can always drive the light source assembly 3 to rotate back and forth.
