[0041] Example 1

[0042] like Figures 1-7 As shown in the figure, in this embodiment, a floating photovoltaic displacement monitoring device is provided, including a floating platform 1, on which multiple floats 3 are uniformly fixedly installed on the lower surface of the floating platform 1; a counterweight box 4 is provided below the floating platform 1, and a counterweight block 401 is provided inside the counterweight box 4; the floating platform 1 and the counterweight box 4 are connected by a connecting rod 5; a power module 8 and a control module 12 are installed inside the counterweight box 4; wherein, a receiving cavity 101 is provided around the floating platform 1, and a photovoltaic panel 6 is provided inside the receiving cavity 101; a sealing gasket is provided at the opening of the receiving cavity 101; and a hydraulic cylinder 7 is provided on the floating platform 1 for driving the photovoltaic panel 6 to slide out or slide into the receiving cavity 101; the output shaft of the hydraulic cylinder 7 is connected to the side wall of the corresponding photovoltaic panel 6.

[0043] As shown in Figure 6 The floating platform 1 is square in shape, and each side of the floating platform 1 is provided with a containing cavity 101. Adjacent two containing cavities 101 are staggered in layout. Each containing cavity 101 is provided with a photovoltaic panel 6. The floating platform 1 is provided with a plurality of oil cylinders 7. Each photovoltaic panel 6 is driven to slide by two oil cylinders 7.

[0044] As shown in Figure 2 When the output shaft of the oil cylinder 7 is extended, the output shaft of the oil cylinder 7 drives the photovoltaic panel 6 to slide out of the inside of the containing cavity 101. At this time, the photovoltaic panel 6 is exposed outside. In a sunny environment, after the photovoltaic panel 6 is illuminated, the photovoltaic panel 6 converts light energy into electrical energy.

[0045] As shown in Figure 1 When the output shaft of the oil cylinder 7 is retracted, the output shaft of the oil cylinder 7 drives the photovoltaic panel 6 to retract into the inside of the containing cavity 101. At this time, the photovoltaic panel 6 is stored in the inside of the containing cavity 101. In a night or typhoon environment, it is beneficial to protect the photovoltaic panel 6 from being damaged.

[0046] The upper surface of the floating platform 1 is fixed with a mounting plate 2 for mounting detection equipment. The surface of the mounting plate 2 is uniformly provided with a plurality of mounting holes. The photovoltaic panel 6, the power module 8, the control module 12, the oil cylinder 7 and the detection equipment connected through the mounting plate 2 are electrically connected,

[0047] The monitoring equipment on the mounting plate 2 performs real-time monitoring. The monitoring equipment transmits the monitored data to the control module 12. The control module 12 transmits the received data to an external terminal through a wireless module. When it is sunny, the control module 12 controls the oil cylinder 7 to start. The oil cylinder 7 drives the photovoltaic panel 6 to extend and unfold from the containing cavity 101. The photovoltaic panel 6 converts light energy into electrical energy. The power module 8 stores the converted electrical energy. When it is a severe environment, the control module 12 controls the oil cylinder 7 to start. The oil cylinder 7 drives the photovoltaic panel 6 to retract into the containing cavity 101, thereby effectively protecting the photovoltaic panel 6.

[0050] When the floating platform 1 floats horizontally in the water, the floating box 902 is suspended on the support frame 901.

[0051] When the floating platform 1 is tilted and shaken in water, the floating box 902 on the side where the floating platform 1 is tilted downward is immersed in water and supports the side where the floating platform 1 is tilted downward by buoyancy.

[0052] A limiting pressing plate 903 is arranged above each floating box 902 on the supporting frame 901, and the lower surface of the limiting pressing plate 903 is parallel to the upper surface of the floating platform 1.

[0053] As shown in Figure 5 When the floating box 902 is rotated upward, the side wall of the floating box 902 is against the side wall of the limiting pressing plate 903, the floating box 902 is in the maximum rotation range, at this time, the floating box 902 is parallel to the upper surface of the floating platform 1, and the floating platform 1 can be better supported by buoyancy at this time.

[0054] A top pressing table 904 is arranged on the side wall of the supporting frame 901, when the floating box 902 is against the side wall of the top pressing table 904, the floating box 902 is in an inclined state, and when the floating platform 1 is tilted downward, the floating box 902 can be ensured to rotate toward the limiting pressing plate 903, the stability of the floating box 902 to the floating platform 1 is increased, and the floating platform 1 is further prevented from tilting and overturning.
