Water surface working platform

The invention relates to the field of water quality monitoring, in particular to a novel water surface working platform which can be massively installed on water-quality on-line monitoring equipment. The water surface working platform comprises an upper deck and a glass fiber-reinforced plastic grating, wherein a protective handrail is arranged on the upper surface of the upper deck, and one or more independent sealed cabins are arranged at the bottom of the upper deck. The water surface working platform further comprises a submerged shackle and a platform submerged object, wherein the submerged shackle is connected with the bottoms of the independent sealed cabins through one or more submerged anchor chains, and the platform submerged object is connected with the submerged shackle through the submerged anchor chains. According to the water surface working platform, a solar panel can be installed on a device box, a storage battery, a data collection and sending module and the like can be installed in the device box, four lifting lugs on the edge of the deck can also serve as bitts, and a worker can come in and go out conveniently through a working door. A monitoring instrument installation pipe penetrates through the water surface working platform from top to bottom and extends into water.
