[0024] In this example, under the action of the floating board 5 and the pontoon bar 7, the support base 1 can be supported, which is convenient for supporting the inverter 4. When it is windy and rainy, the water suction pump 12 is running, and the water suction pump 12 absorbs water through the water suction pipe 13, so that the water enters the inside of the pontoon bar 7, which can increase the weight of the floating board 5 and the pontoon bar 7 and enhance the stability of the support base 1 in windy and rainy weather. When the drainage pump 10 is running, the water inside the pontoon bar 7 is discharged through the drainage pipe 11, so that the weight of the floating board 5 and the pontoon bar 7 is reduced, and the support base 1 can be supported.

[0025] like Figure 2and Figure 5 As shown, the utility model provides a mounting device for a water photovoltaic array inverter 4, a limiting structure is arranged between the mounting bar 6 and the mounting sleeve 9, the limiting structure includes a groove 8, the groove 8 is opened on both sides of the mounting bar 6, a fixing rack 21 is arranged inside the groove 8, a fixing tooth plate 24 is movably inserted inside the groove 8, the fixing tooth plate 24 is clamped with the fixing rack 21, a clamping screw 23 is movably inserted on both sides of the mounting sleeve 9, the clamping screw 23 is rotatably connected with the fixing tooth plate 24, a pressure rod 22 is movably inserted on both sides of the mounting sleeve 9, the pressure rod 22 is connected with the fixing tooth plate 24, a pressure spring 26 is sleeved on the surface of the pressure rod 22, a connecting plate 25 is installed at one end of the pressure rod 22, and the connecting plate 25 is movably sleeved on the surface of the clamping screw 23;

[0026] In this example, when the floating plate 5 and the buoy bar 7 are damaged, the user rotates the clamping screw 23, and the clamping screw 23 drives the fixing tooth plate 24 to move. Under the action of the pressure rod 22 and the clamping spring 26, the fixing tooth plate 24 can prevent the fixing tooth plate 24 from rotating with the clamping screw 23.

When the inverter 4 contacts the card block 15, the card block 15 is squeezed into the interior of the mounting block 14, so that the card block 15 is squeezed into the interior of the mounting block 14, compressing the retaining spring 17. When the inverter 4 is fully inserted into the interior of the assembly groove 3, the card block 15 pops out under the action of the retaining spring 17, and the card block 15 fits with the upper end of the inverter 4, thereby facilitating the rapid installation of the inverter 4.
