Problems solved by technology

[0004] Before the research and development of the present invention, due to the uncertainty and persistence of the floating film, and the hysteresis caused by its harmful effect, farmers mostly ignored the treatment of the floating film, or only removed the floating film by manual fishing. low efficiency, poor effect
There is no cheap, environmentally friendly, time-saving and labor-saving physical method to automatically remove the floating film in the industry.

Embodiment Construction

[0050] 1. Before using this invention, check whether the power supply is sufficient, whether there is water leakage or water seepage in the body, and whether the rotating buckle (3) is stuck. When in use, just turn on the power switch and put it in the pond. During use, make proper inspections to observe whether the salvage machine is working normally and whether there are accidents such as grounding. After use, remove the power supply and clean the machine in time, especially salvage the parts such as the propeller (1), the floating film collector (2), the floating film storage device (4) and the anti-air lift (8).

[0051] 2. When the area of ​​the pond is too large or the floating film is relatively concentrated, the working range of the salvage machine can be circled with the barrier (17) according to the position of the floating film. When in use, unfold the barrier, insert the metal sticks at both ends on the bank of the pond, circle the working range of the salvage mac...

Abstract

The invention relates to an automatic fishing device for a prawn shed aquaculture water surface floating film. The floating film generally refers to an organic matter layer floating on the water surface in the aquaculture process, can hinder oxygen exchange between water and air, consumes oxygen, generates harmful substances and increases the aquaculture risk. Due to uncertainty and sustainabilityof the floating film and hysteresis caused by the harmful effect of the floating film, treatment of the floating film is generally ignored in the industry, and no cheap, environment-friendly and labor-saving floating film removing device exists in the industry at present. According to the automatic fishing device, the physical fishing mode, a gas stripping principle and an automatic steering technology are adopted to continuously and automatically fish and separate the floating film on the water surface, and a barrier is used for cooperation, so that the floating film fishing efficiency can be greatly improved, and the practicability of the device is enhanced. The device provides a new method for fishing and separating the floating film in aquaculture.

Description

technical field [0001] The invention relates to an automatic fishing device for floating membranes, in particular to a device suitable for automatic fishing of floating membranes on the water surface of prawn small shed cultivation. Background technique [0002] Floating film generally refers to a layer of film formed by floating and accumulating dead algae and organic matter during the aquaculture process. Under aerated conditions, the surface tension of the air bubbles can cause dead algae to aggregate with various organic debris in the water, forming a thicker floating film layer on the water surface. The floating film will constantly surface or sink into the water in various changes of the water body. [0003] Floating film has two main hazards to aquaculture. On the one hand, a large number of floating membranes cover the surface of the water body, hindering the oxygen exchange between water and air; on the other hand, when the dead algae and organic debris in the flo...
