Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a bracket for a ducted fan. Background Art

[0002] The traditional manual boat-boat feeding operation is labor-intensive and has high labor costs. Farmers rely entirely on experience and scatter the bait at random, which cannot meet the requirements of uniform feeding and pesticide application in the entire pond for river crab farming. This is the shortcoming that needs to be filled in the current farming industry. At the same time, the problems of aging and lack of labor faced by river crab farming also make the mechanization and automation of feeding operations particularly important. Moreover, automated feeding boats require a power source to push them. However, crab ponds are different from shrimp ponds. Generally, there are large areas of aquatic plants, which can purify the water quality of crab ponds, increase the dissolved oxygen content of water bodies, provide shade and cool down, and provide river crabs with plant feed and a safe place to live and molt. However, most traditional unmanned boats in the past were propelled by underwater propellers. Even if the propellers were not entangled in aquatic plants, the aquatic plants damaged by the propellers would cause economic losses. Therefore, in order to prevent the propellers from being entangled in aquatic plants, it is of certain economic value to develop an unmanned boat that does not require underwater propulsion. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a bracket for a ducted fan, which is used to solve the problem that most traditional unmanned boats in the prior art are propelled by underwater propellers, and the underwater propellers will be entangled by aquatic plants in crab ponds and the underwater propellers will also destroy the aquatic plants.
