Height-adjustable bearing support assembled on water surface under assistance of buoyancy

The invention belongs to the technical field of indoor pool test equipment, and provides a buoyancy-assisted water surface assembled height-adjustable bearing bracket, which comprises a plurality of self-floating brackets, a test load bracket, an inflation and deflation pipeline valve group, an inflation hose group and an inflation air compressor, the test load support is erected on the uppermost layer of the self-floating support assembly, the plurality of self-floating supports are all provided with buoyancy units, the buoyancy units are connected with the inflation and deflation pipeline valve group through the inflation hose group, and compressed air is provided by the inflation air compressor. The buoyancy-assisted water surface assembled height-adjustable bearing support is used for large device tests of indoor pools, the height of the support can be flexibly adjusted according to test requirements, then the underwater depth of a carried test device is adjusted, and the limitation of the lifting height
