The right end of the rotating shaft 66 is fixed with a handle, and a synchronous belt 68 is wound around the middle of the rotating shaft 66 through a synchronous wheel.

[0036] Reference Figure 5 As shown, the fixing mechanism 7 includes a second mounting frame 71, a connecting frame 72, a torsion spring 73, a wedge block 74 and a first spring 75. The second mounting frame 71 is welded symmetrically on the right side of the placement plate 4. A connecting frame 72 is rotatably provided on the right side of the second mounting frame 71. The connecting frame 72 and the adjacent second mounting frame 71 are symmetrically connected with torsion springs 73. A wedge block 74 is slidably provided on the left side of the connecting frame 72. The wedge block 74 can clamp the photovoltaic panel 5. A first spring 75 is connected between the wedge block 74 and the adjacent connecting frame 72.

[0037] Reference Figure 6 and Figure 7 As shown, the locking mechanism 8 includes a fixing rod 81, a push rod 82, a second spring 83, a first slide rod 84, a connecting plate 85, a first wedge rod 86, a fixing block 87, a third spring 88 and a first clamping rod 89. The fixing rods 81 are welded symmetrically on both the front and rear sides of the mounting plate 3. The fixing rods 81 on the same side are slidably connected with the push rods 82. The upper side of the push rods 82 is an elastic band. The upper part of the push rods 82 is slidably connected to the placement plate 4. The second spring 83 is connected between the push rods 82 and the adjacent lower fixing rods 81. The first slide rods 84 are symmetrically arranged on the front and rear sides of the top of the floating board 1. The connecting rods 84 are slidably connected between the first slide rods 84 on the same side. The connecting plate 85 and the connecting plate 85 are connected to the bottom of the adjacent push rod 82, and a first wedge rod 86 is welded on the right side of the top of the connecting plate 85, and a fixed block 87 is welded on the left side of the upper part of the first mounting frame 65. The rotating shaft 66 is rotatably connected to the adjacent fixed block 87, and a first clamping rod 89 is slidably provided on the left side of the fixed block 87. The first clamping rod 89 can clamp the rotating shaft 66 and prevent it from rotating. The first clamping rod 89 is engaged with the adjacent rotating shaft 66, and a third spring 88 is connected between the first clamping rod 89 and the adjacent fixed block 87. The first clamping rod 89 is in contact with the adjacent first wedge rod 86, and the connecting plate 85 is slidably connected to the adjacent mounting rod 61.

[0038] When the photovoltaic power generation device is needed, the staff can first adjust the angle of the placement plate 4 according to the angle at which the photovoltaic panel 5 needs to be placed. The staff can rotate the shaft 66 on one side through the handle as needed, and rotate the shaft 66 on the other side through the synchronous belt 68 and the synchronous wheel. The rotation of the shaft 66 drives the gear 67 to rotate, and the rotation of the gear 67 drives the rack 63 to move downward. The rack 63 moves downward and drives the push rod 62 to move downward. The push rod 62 moves downward and can drive the placement plate 4 to rotate through the slide block 64. The rotation of the placement plate 4 will cause the elastic band part of the push rod 82 to deform adaptively. When the placement plate 4 is rotated to a suitable angle, the handle can be stopped, and then The photovoltaic panel 5 can be placed on the placement plate 4, and the photovoltaic panel 5 can be well irradiated by the sun. During the placement process of the photovoltaic panel 5, the photovoltaic panel 5 continues to move after contacting the wedge block 74, so that the wedge block 74 can move to the right, and the first spring 75 is compressed. After the photovoltaic panel 5 passes over the wedge block 74, the wedge block 74 moves to the left and resets under the action of the first spring 75. The wedge block 74 moves to the left and can cooperate with the placement plate 4 to clamp the photovoltaic panel 5. The photovoltaic panel 5 continues to move after contacting the push rod 82. Because the elastic band part of the push rod 82 cannot be contracted too much, when the photovoltaic panel 5 is placed on the placement plate 4, the photovoltaic panel 5 will push the push rod 82 to move downward, and the second spring 83 is compressed. , the push rod 82 moves downward to drive the connecting plate 85 and the first wedge rod 86 to move downward, the first wedge rod 86 moves downward to drive the first clamping rod 89 to move rightward, the third spring 88 is compressed, and the first clamping rod 89 moves rightward to clamp the rotating shaft 66, so that the adjusted placement plate 4 angle can be fixed, and then the staff can place the device on the lake with sufficient sunshine, and the floating board 1 and the pontoon 2 can make the device float on the water, and the photovoltaic panel 5 can collect solar energy and convert it into solar energy. When the photovoltaic panel 5 needs to be removed without using the device to generate electricity, the staff can move the connecting frame 72 to drive the wedge block 74 and the first spring 75 The torsion spring 73 is deformed, and the wedge block 74 rotates and no longer jams the photovoltaic panel 5. The staff can then take out the photovoltaic panel 5 and loosen the connecting frame 72. Under the action of the torsion spring 73, the connecting frame 72, the wedge block 74 and the first spring 75 rotate and reset. After the photovoltaic panel 5 is taken out, the photovoltaic panel 5 no longer presses the push rod 82. Under the action of the second spring 83, the push rod 82, the connecting plate 85 and the first wedge rod 86 move upward and reset. The first wedge rod 86 moves upward and no longer resists the first clamping rod 89. Under the action of the third spring 88, the first clamping rod 89 moves to the left and resets. The first clamping rod 89 moves to the left and no longer jams the rotating shaft 66. In this way, the angle of the placement plate 4 can be adjusted again.

[0039] Example 2

[0040] Based on Example 1, Figure 1 , Figure 8and Fig. 9 As shown, it also includes a splicing mechanism 9, which can splice two adjacent floating photovoltaic power generation devices together. The splicing mechanism 9 includes a first mounting block 91, a clamping column 92, a third mounting frame 93, a second wedge rod 94, a fourth spring 95, a clamping block 96, a fifth spring 97 and a second slide bar 98. The first mounting block 91 is fixedly connected to the left rear side of the top of the floating board 1 by bolts, and a clamping column 92 is welded between the middle part of the first mounting block 91 and the floating board 1. The second slide bar 98 is welded to the left front side of the top of the floating board 1. A block 96 is slidably provided on the rod 98, a fifth spring 97 is connected between the block 96 and the lower side of the second sliding rod 98, the rear side of the block 96 is connected to the connecting plate 85 on the front side, a third mounting frame 93 is welded to the left front side of the top of the floating plate 1, a second wedge rod 94 is slidably provided on the third mounting frame 93 in a left-right symmetrical manner, the second wedge rods 94 are all in contact with the block 96, the second wedge rods 94 can cooperate with the clamping column 92 to achieve a splicing function, and a fourth spring 95 is symmetrically connected front and back between the outer side of the second wedge rod 94 and the third mounting frame 93.

[0041] In order to absorb more solar energy and convert it into electrical energy, more photovoltaic panels 5 need to be placed. The staff can splice multiple devices together. When splicing, the clamping column 92 can be placed between the second wedge rods 94 of another device. Then the photovoltaic panel 5 can be placed on the placement plate 4, and the connecting plate 85 moves downward to drive the clamping block 96 to move downward. The fifth spring 97 is compressed, and the clamping block 96 moves downward to drive the second wedge rod 94 to move inward. The fourth spring 95 is stretched, and the second wedge rod 94 moves inward to clamp the clamping column 9 2, so that the clamping column 92 cannot be moved out from between the second wedge-shaped rods 94, so that the two floating boards 1 can be spliced ​​together, so that more photovoltaic panels 5 can be placed on the water surface to absorb solar energy. When the device is not needed, the connecting plate 85 moves upward to drive the clamping block 96 to move upward, the fifth spring 97 is reset, the clamping block 96 moves upward and no longer resists the second wedge-shaped rod 94. Under the action of the fourth spring 95, the second wedge-shaped rod 94 moves outward and resets and no longer clamps the clamping column 92, so that the clamping column 92 can be separated from the second wedge-shaped rod 94, and then the two floating boards 1 are separated.

[0042] Reference Figure 1 and Fig.10As shown, it also includes an anchoring mechanism 10, which can fix the floatable photovoltaic power generation device on the lake surface. The anchoring mechanism 10 includes a mounting seat 101, a turning handle 102, a winding wheel 103, a pull rope 104 and a fixed anchor 105. The mounting seat 101 is symmetrically fixed to the right side of the top of the floating board 1 through bolts, and the winding wheel 103 is rotatably connected between the mounting seats 101. The turning handle 102 is fixed to the rear side of the winding wheel 103. A pull rope 104 is wound on the winding wheel 103, and a fixed anchor 105 is provided at the other end of the pull rope 104. The fixed anchor 105 can play a fixing role.

[0043] Reference Figure 1 , Fig.11 and Fig.12 As shown, it also includes a locking mechanism 11, which can fix the winding wheel 103. The locking mechanism 11 includes a turntable 111, a push block 112, a second mounting block 113, a second clamping rod 114 and a sixth spring 115. A turntable 111 is provided on the front side of the winding wheel 103, a push block 112 is provided on the right side of the front connecting plate 85, a second mounting block 113 is welded to the lower part of the front mounting seat 101, and a second clamping rod 114 is slidably provided on the second mounting block 113. The second clamping rod 114 can clamp the turntable 111 to fix the winding wheel 103. The sixth spring 115 is connected between the second clamping rod 114 and the second mounting block 113. The second clamping rod 114 is in contact with the push block 112, and a circle of clamping holes that fit with the second clamping rod 114 are opened on the turntable 111.

[0044] Before placing the device on the water surface, a corresponding length of the pull rope 104 can be released according to the depth of the lake. The staff can rotate the handle 102 to drive the reel 103 to rotate and release the pull rope 104. After the device is placed, the fixed anchor 105 can be thrown into the lake, so that the floating board 1 can be fixed there by the fixed anchor 105. The connecting plate 85 moves downward to drive the push block 112 to move downward. The push block 112 moves downward to drive the second clamping rod 114 to move backward and clamp into the clamping hole of the rotating disk 111. The sixth spring 115 is stretched, and the first spring 115 is pulled back. The second clamping rod 114 can clamp the turntable 111, making the turntable 111 unable to rotate, and further making the winding wheel 103 unable to rotate, so as to prevent the floating board 1 from floating around on the water surface when the wind and waves are too strong, thereby affecting the photovoltaic panel 5 to absorb solar energy. The connecting plate 85 moves upward to drive the push block 112 to move upward and no longer resist the second clamping rod 114. Under the action of the sixth spring 115, the second clamping rod 114 moves forward and no longer clamps the turntable 111. In this way, the turning handle 102 can be rotated in the opposite direction to drive the winding wheel 103 to rotate the winding rope 104.
