as shown in fig. 18 and 19, the three groups of fixing blocks 483 are all provided with annular motors connected with the rotating sleeve 482, the three groups of fixing blocks 483 are three groups of fixing blocks 483 which are mutually spaced by 120 degrees, the solar panel and the battery are paved on the shell 41, and the annular motors are connected with the solar panel and the battery through relays; the battery is a commercial lithium battery, the surface of the battery is covered with a heat insulation plate, and the annular motor and the relay are selected from commercial motors or the commercial relays for shape adjustment so as to be adaptively arranged on the device; the shell 41 and the driving ring 42 can be made of rigid foam, so that the buoyancy of the floating stabilizer 4 on the water surface of the water body is ensured;
the working principle of the floating stabilizer 4 is as follows:
the bottom of the light collector is clamped and fixed with the connecting table 432, the other end of the optical fiber connected with the light collector passes through the communicating hole arranged on the central rod 43, the optical fiber is sleeved in the sludge by using the metal sleeve, and then the metal sleeve shell is taken out, so that the optical fiber is scattered and distributed in the sludge;
the driving motor is started to rotate the driving gear 46, and under the transmission action of the driving gear 46 and the annular fluted disc 421 of the two groups of driving rings 42, the two groups of driving rings 42 respectively rotate clockwise and anticlockwise, so that a stable dynamic balance state is formed,
when the water surface of the water body fluctuates greatly, the light collector always keeps the direction of gravitation, namely keeps the vertical direction due to the action of the central rod 43, at the moment, the related components of the shell 41 can swing under the action of the sphere 431 of the central rod 43 and the sphere groove 441 of the carrier plate 44, in the swinging process, the first air bag 45 between the shell 41 and the connecting table 432 can be extruded or stretched,
in the dynamic balance air chamber formed by the third air bag 484 and the first air bag 45 using the stabilizer 48, for example, when the first air bag 45 is pressed, the corresponding third air bag 484 is protruded downward, and in the protruded state, the rotation shaft 481 is pushed to the water surface side using the third air bag 484,
therefore, under the above action, the lifted stabilizer 48 can keep the disc 485 in contact with the water body, that is, if the shell 41 is inclined downwards in the left direction as shown in fig. 17, the first air bag 45 in the left direction will be stretched, in the dynamic balance air cavity formed by the third air bag 484 and the first air bag 45, the third air bag 484 will shrink upwards, the disc 485 will be relatively close to the shell 41, the first air bag 45 in the right direction will be extruded, the third air bag 484 in the corresponding position will extend downwards, the disc 485 will be relatively far away from the shell 41, at this time, when the transmission ring 42 rotates, the rotating rod 481 and the rotating sleeve 482 of each stabilizer 48 rotate through the transmission action of the driving gear 46 and the first bevel gear 486 and the second bevel gear 487, and the stable dynamic balance state is formed in the water body through the two groups of discs, so that the risk of rolling over the floating stabilizer 4 will be greatly reduced, and the problem that the disc 485 of the stabilizer 48 will touch the bottom or be separated from the water body due to the water body will be avoided.
