Initially, two kickboards 11 are close to each other, and flexible subassembly 5 is for shortening the state, and the position of closing plate is in the intermediate position in water storage chamber, and photovoltaic board 3 tends to be parallel with kickboard 11, and two adjacent showy subassemblies 1 do not connect through coupling assembling 4.
During operation, two adjacent floating assemblies 1 are spliced through the connecting assembly 4, namely the plug connector 41 is fixedly connected with the limiting piece 42, so that the floating assemblies 1 form a water floating type photovoltaic power station, for example, one of the connected floating assemblies 1 is used, the gravity of the photovoltaic panel 3 is utilized to immerse one end of the water inlet cavity 13, the water level of the water inlet cavity 13 just can be irrigated into the water storage cavity 12, the gravity center of the floating panel 11 is sunk, the draught depth of the floating panel 11 on the water surface is improved, the stability of the device is improved, the liquid conversion between the water storage cavity 12 and the water inlet cavity 13 is maintained through the overflow cavity 14, when the water surface fluctuates, the ripple can penetrate through the overflow cavity 14, the vibration duration and the amplitude of the floating panel 11 can be rapidly reduced, so that the floating assembly 1 has the basis for opening the photovoltaic panel 3, and then follow spot and survey the real-time angle of locating the sun through solar energy ware, thereby reach the control maincenter with the testing result upload, thereby make the control maincenter adjust the flexible length extension of retractable assembly 5, and then the extension length through retractable assembly 5 drives kickboard 11 and removes, thereby when kickboard 11 removes, coupling assembling 4 slides on sliding tray 1102, thereby pass through control maincenter feedback to supporting component 2 according to coupling assembling 4 at sliding tray 1102's sliding distance, thereby make supporting component 2's inclination take place to rotate, adjust photovoltaic panel 3's angle to relative with the sun, realize the normal use to photovoltaic power plant this moment.
However, when the wind sensor detects that the wind on the water surface reaches or exceeds 7 grades of wind, the wind can affect the safe use of the photovoltaic panel 3, so that the wind sensor uploads the detected result to the control center, and then the control center makes a contraction instruction on the telescopic assembly 5 to control the distance between the two floating plates 11 to be reduced, so that the position of the photovoltaic panel 3 and the floating plates 11 are parallel to each other, it should be noted that, in the use process, the control instruction of the wind sensor is prior to the instruction of the solar light tracker, that is, when the wind greater than or equal to 7 grades of wind is generated under the fine weather and the duration is long (the duration is greater than or equal to 5 minutes), the telescopic assembly 5 performs the contraction process without executing the instruction of the solar light tracker, so as to achieve the purpose of protecting the photovoltaic panel 3, and when the angle of the photovoltaic panel 3 is adjusted under the strong wind weather, at the moment, the sealing plate moves towards one end far away from the photovoltaic plate 3 through the contraction of the air pressure telescopic rod, so that the volume of a water storage cavity in the water storage cavity 12 is increased, the gravity of the floating plate 11 is continuously increased, so that the draught of the floating plate 11 in water is increased, and the movement of the sealing plate is dually controlled by the angles of the wind sensor and the photovoltaic plate 3, namely, when the wind sensor detects that the wind power is more than or equal to 7 levels and the photovoltaic panel 3 and the floating plate 11 are approximately parallel, the control center controls the sealing plate to move, but when the photovoltaic panel 3 alone rotates to be parallel to the floating plate 11, the sealing plate does not move, when the wind sensor alone detects that the wind power is more than or equal to 7 grades, the condition of instantaneous wind power can occur, the sealing plate is not moved, and the influence of continuous reciprocating movement on the sealing effect of the sealing plate is avoided.
Simultaneously because photovoltaic board 3 covers on the surface of water for a long time to can produce relative influence to quality of water, for the convenient influence to quality of water changes, thereby ensure that water quality sensor contacts with the surface of water all the time, upload the result that detects to the control maincenter through the water quality testing sensor, and upload data to research center through the control maincenter, record the influence of showy formula photovoltaic power plant's in service behavior on the surface of water on this, use as the data of scientific research with this.
Example 2
Since the solar tracker in embodiment 1 can adjust the angle of the photovoltaic panel 3 only according to the seasonal change angle of the sun, the photovoltaic panel 3 cannot sufficiently face the sun when the sun is in the east-west fall, and the photovoltaic panel 3 cannot sufficiently utilize the sunlight.
Furthermore, on the basis of embodiment 1, a rotating part is arranged on one side of each floating plate 11 far from the water surface, the supporting component 2 is rotatably connected onto the rotating part, the rotating part stretches across the two floating plates 11, the rotating axis of the rotating part is located on the fixed floating plate 11, the rotating plates are in interference connection on the moving floating plates 11, the rotating angle of the rotating part on the fixed floating plate 11 is 135 degrees, and the rotating power of the rotating part is a rotating motor, wherein the work of the rotating motor is controlled by a solar light tracker, so that the photovoltaic panel 3 can rotate along with the movement of the sun one day while meeting the seasonal inclination angle, and the conversion rate of light is improved.
