Multifunctional underwater working device for fishery

Abstract

The invention discloses a multifunctional underwater working device for fishery. The multifunctional underwater working device comprises a device main body, wherein a driving system for providing power is arranged on the device main body; an underwater camera system and a control system are mounted at the top of the device main body; underwater lighting devices are respectively mounted on two sides of the underwater camera system and the control system; a cavity which passes through transversely is formed inside the device main body; a functional unit component is mounted at the head of the cavity; a conveying pipe and an umbilical cable are arranged at the tail part of the cavity; one end of the conveying pipeline is communicated with the tail part of the cavity; the other end of the conveying pipeline is connected with a ship-mounted pump; one end of the umbilical cable is connected with the driving system, the underwater camera system, the control system and the underwater lighting devices; the other end of the umbilical cable is connected with the ship-mounted pump and a ship-mounted operation platform.

Description

technical field [0001] The invention relates to the field of fishery mechanical devices, in particular to a multifunctional underwater operation device for fishery. Background technique [0002] The total length of my country's mainland coastline is 32,647 kilometers, including 18,412 kilometers of mainland coastline and 14,235 kilometers of island coastline. Aquaculture enterprises use coastline resources to carry out various aquaculture production activities, including shallow sea raft aquaculture, shallow seabed multiplication aquaculture, and seawater cage aquaculture. The aquaculture area is 650,000 hectares, accounting for 40.1% of mariculture, and the aquaculture output is 6.76 million tons, accounting for 51.3% of mariculture. Shellfish and algae are the main types of shallow sea raft culture and bottom sowing culture. While obtaining a large amount of economic benefits, production and management operations such as harvesting bottom-sowed aquatic products and clean...

Problems solved by technology

For example, the underwater cleaning of the nets of the net cages is mainly carried out by divers who dive into the water with special cleaning equipment to clean the nets of each net cage one by one. life safety

The acquisition of sediment in the breeding area, the monitoring of the anchor rope of the cage, and the underwater inspection of the breeding status of the deep-water cage all need to be completed by special underwater operations. The depth exceeding 20m can be reached by unconventional divers, and the cost of professional deep diving Expensive, unbearable for ordinary farming enterprises

Therefore, the limitation of water depth, the danger of operation, and the high cost of operation of underwater special operations have seriously hindered the development of the industry.
