According to buoyancy formula, it is 147kg/ blocks that main floating body, which can provide buoyancy, and it is 68kg/ that modular support floating body, which can provide buoyancy,
Block, then gross buoyancy be：147kg/ block × 117 piece+68kg/ block × 104 piece=24271kg.
Therefore, the present embodiment can fully ensure that the buoyancy demand of water surface photovoltaic generating system.
Installed part workload computing：
It is as follows that the present embodiment using 88 pieces of photovoltaic modulies as a unit calculates its installed part number：
Main floating body connecting bolt：9 row × 24/row=216
Main floating body and modular support floating body connecting bolt：9 row × 52/row=468
Component caging bolt：88 pieces × 2/block=176
Installed part total amount is 860, and the quantity that floating body and component installed part workload averagely arrive every piece of photovoltaic module is about
9.77 part.
Compared with patent US2014224165A1, unit photovoltaic module installed part workload have dropped about 6.Therefore, originally
Embodiment can reduce installed part workload, save cost of labor.
Floating body cost calculation：
The present embodiment is using 88 pieces of photovoltaic modulies as floating body material, wherein floating body needed for a unit calculating monolithic photovoltaic module
Wall thickness and main float value are similar with patent US2014224165A1, CN105186968A, are respectively：
Floating body wall thickness：Upper surface 5mm, remainder 3mm
Float：200mm
Single floating body material requested：
Main floating body：8.67kg/, modular support floating body：It is 6.77kg/ individual
Each floating body material needed for photovoltaic cells is：117 × 8.67kg/+104 × 6.77kg/=1718.47kg
Average monolithic photovoltaic module material requested is：1718.47kg/88=19.5kg
Then compared with patent US2014224165A1, CN105186968A, monolithic photovoltaic module saves material about 1.3kg.
Therefore, the present embodiment can reduce material usage, cost-effective.
Other unspecified parts are prior art.Although above-described embodiment is made that to the present invention and retouched in detail
State, but it is only part of the embodiment of the present invention, rather than whole embodiments, people can also according to the present embodiment without
Other embodiment is obtained under the premise of creativeness, these embodiments belong to the scope of the present invention.
