The partition 14 is provided in the cavity 13, and the pontoon body 10 can be supported by the partition 14, further improving the structural strength of the pontoon body 10. Specifically, the plug-in groove 12 extends from the side wall 11 along the partition 14 toward the center of the pontoon body 10, that is, the plug-in groove 12 is provided at the position where the partition 14 is located, so that the plug-in portion 20 is plugged into the partition 14, which has better connection strength and connection reliability.

[0049] In some optional embodiments of the present application, the fasteners may also be sequentially passed through the cover plate 15, the partition plate 14, the plug-in portion 20 and the bottom plate 16, so that the fasteners are passed through a deeper position of the pontoon body 10, further improving the stability of the fasteners to the plug-in portion 20.

In this way, the fastener can be smoothly penetrated through the cover plate 15, the partition plate 14 and the plug-in portion 20 through the first through hole 151, the second through hole 141 and the third through hole 21, thereby improving the convenience of installation.

[0052] In the embodiment of the present application, optionally, the water surface photovoltaic buoyancy box further includes a sealing member; the sealing member is connected to the outer periphery of the first through hole 151 to seal the first through hole 151. The first through hole 151 opened on the cover plate 15 is sealed by the sealing member, so that the cover plate 15 has good sealing performance, and prevents water from penetrating into the buoyancy box body 10 from the first through hole 151. For example, the sealing member can be silicone or rubber, etc., and the embodiment of the present application does not limit the specific type of the sealing member.
