Remote control sea cucumber fishing robot

Abstract

The invention discloses a remote control sea cucumber fishing robot. The remote control sea cucumber fishing robot includes a rack, drivers, a controller which is provided with an image collector andused for collecting and identifying the positions of sea cucumbers in water and controlling the actions of a sea cucumber suction device, and the sea cucumber suction device which is controlled by thecontroller and sucks the sea cucumbers according to the commands of the controller; the sea cucumber suction device is provided with at least one sea cucumber suction cover capable of sucking the seacucumbers, a sea cucumber suction pipeline, a sea cucumber suction hole switch plate which can open a sea cucumber storage box for the sucked sea cucumbers to enter the sea cucumber storage box and transmit sea cucumber suction negative-pressure to the sea cucumber suction pipeline, the sea cucumber storage box, and a water pump which can form the sea cucumber suction negative-pressure in the seacucumber storage box by pumping water; the controller adopts a machine vision tracking and positioning technology to control the propeller drivers to adjust the fishing position of the robot. The remote control sea cucumber fishing robot is simple in structure and convenient to operate, and is provided with the sea cucumber storage box by itself, no long pipeline is needed, the robot can conductfishing operation in a deep water area, and the two-step method of coarse positioning and accurate positioning is adopted to achieve sea cucumber positioning and fishing to further improve the work efficiency.

Description

technical field [0001] The invention belongs to the technical field of sea cucumber cultivation, and in particular relates to a remote-controlled sea cucumber harvesting robot. Background technique [0002] With the improvement of people's living standards, sea cucumbers have become a more common health food on the table, which has greatly promoted the development of sea cucumber farming technology. Among them, the quality of sea cucumbers cultured at the bottom is close to wild, with high nutritional and economic values. It is the most important breeding method of sea cucumber in my country. Bottom-seeding aquaculture refers to a breeding method in which seafood seedlings of a certain specification are placed at a certain density in a suitable sea area to allow them to grow naturally and continuously multiply on the seabed. There are sea cucumbers, abalones, and scallops, etc. It is 10-40m. At present, sea cucumbers are mainly fished by artificial diving due to the reasons...

Problems solved by technology

However, submersible fishing not only has low output and high cost, but also seriously damages the diver's health, which can easily lead to "diving sickness" and other diseases, and there are frequent incidents of diver's death during operation. Aquaculture enterprises urgently need automated equipment to replace manual fishing.

In addition, with the degradation of the breeding environment, the waters suitable for sea cucumber farming in the shallow sea are getting smaller and smaller, and the farming enterprises have an urgent need to transfer the breeding area to deeper sea areas, but how to fish for grown-up products is the key problem that needs to be solved first. Therefore, the difficulty of sea cucumber fishing has seriously restricted the development of sea cucumber aquaculture in my country.

Although underwater intelligent robots have been widely used in marine activities such as search and rescue and salvage, it is also feasible to use intelligent robots to fish sea cucumbers. requirements; and what it usually adopts is to directly absorb sea cucumbers from underwater to the ship, but this method requires a very long pipeline, which is not suitable for sea cucumber harvesting in areas with large water depths. In addition, due to underwater light, suspended matter, water For reasons such as light absorption and scattering, underwater images usually have low contrast and poor quality, which makes automatic identification of sea cucumbers very difficult and the success rate is very low, far inferior to the accuracy of manual identification of sea cucumbers

However, due to the interference of ocean currents on the seabed and the lag of image transmission, fishing by manual remote control is not only very inefficient, but also very difficult.
