Background At present, the aquaculture field mostly adopts a single-layer factory building or an open-air pond to carry out aquaculture operation, and the planar layout causes low land resource utilization rate, and the productivity is improved and depends on transverse expansion, so that the limitation of land resources is obvious. With the development of the aquaculture industry towards intensification and scale, multi-layer aquaculture plants are attracting attention as the capability of significantly improving the production capacity per unit land area. However, the multilayer cultivation mode brings new technical bottlenecks in terms of logistics transportation while improving the space utilization rate. In the prior art, although the space utilization rate of the multi-layer culture factory building can be improved in theory, in actual operation, due to the lack of a high-efficiency coherent vertical conveying system, the transportation of fish frames among floors is dependent on intermittent lifting equipment (such as an elevator type elevator) or manual transportation, so that a logistics link is broken, the waiting time is long, the overall fish outlet efficiency is low, the productivity advantage of the multi-layer factory building cannot be fully converted into the operation efficiency advantage, and the popularization and the application of the mode are severely restricted. At present, equipment such as a fish pump which is commonly used for vertical transportation of aquatic products has certain transportation capability, but mechanical damage and stress reaction are easily caused to fish bodies in the transportation process. The fish sucking pump sucks the fish body through high-speed water flow, and in the process, the fish body can experience pressure shock, friction and mechanical collision with the pipe wall, so that the problems of scale falling, body surface mucous membrane damage, fin breakage and the like are caused, and the survival rate of aquatic products and commodity quality are seriously influenced. In addition, in the whole process from the culture pond to the transport vehicle, the existing conveying system is always in a fragmentation state, and all links lack of automatic connection, and a large amount of manual participation is needed for operations such as capturing, framing, transferring, loading and the like, so that the labor intensity is high, the labor cost is high, the product quality and the operation safety risk are easily introduced due to inconsistent operation, and the large-scale and standardized operation is difficult to realize. Therefore, developing an automatic vertical conveying device and an integrated conveying system suitable for a multi-layer aquaculture factory building to truly exert the spatial advantage of a multi-layer aquaculture mode, and improving the overall operation efficiency and the product quality has become a key technical requirement for promoting the upgrading of the aquaculture industry.
