Fishery net cage device capable of being automatically regulated and controlled based on temperature changes

Abstract

The invention belongs to the field of fishery, and particularly relates to a fishery net cage device capable of being automatically regulated and controlled based on temperature change. The device comprises a first bracket and a second bracket, a frame is fixedly connected between the first bracket and the second bracket, transparent glass is embedded at the upper side and the lower side of the frame, and a plurality of disturbance mechanisms are arranged in the frame. A sliding rod is slidably connected between the first bracket and the second bracket, a net cage is fixedly connected to the sliding rod, the second bracket is designed in a hollow manner, the second bracket is communicated with the frame, a rotating shaft is rotatably connected to the second bracket, and a first wire wheeland a second wire wheel are connected to the rotating shaft in a sleeving manner. Steel wire ropes are wound on the first wire wheel and the second wire wheel. The device can automatically ascend anddescend a net cage according to different air temperatures in winter and summer seasons, labor loss caused by manual regulation and control is avoided, and timeliness of regulation and control of thenet cage is guaranteed.

Description

technical field [0001] The invention belongs to the field of fishery, and in particular relates to a fishery net cage device that can be automatically regulated based on temperature changes. Background technique [0002] Cage fish farming is a new technology for the development of intensive production in today's world aquaculture industry. It has the advantages of high output, low cost, small investment, easy management, land saving, water saving and energy saving, and effective development of large water surface fisheries in rivers, lakes and reservoirs. . [0003] When carrying out net cage fish farming in rivers, it is often necessary to adjust the depth of the net cage in the water according to the changes of the seasons. In summer, the temperature is high and the solubility of oxygen in the water is reduced. The fish will have difficulty breathing, so they like to go to the water surface and absorb the oxygen in the air. Oxygen, at this time, the net cage needs to be r...

Problems solved by technology

[0003] When carrying out net cage fish farming in rivers, it is often necessary to adjust the depth of the net cage in the water according to the changes of the seasons. In summer, the temperature is high and the solubility of oxygen in the water is reduced. The fish will have difficulty breathing, so they like to go to the water surface and absorb the oxygen in the air. Oxygen, at this time, the net cage needs to be raised to the water surface. In winter, due to the low temperature, the water surface temperature is low, which is not suitable for fish to survive, and the underwater temperature is high, so the net cage needs to be lowered to the water in winter. Generally, it is adjusted by manually moving the cages according to the changes of the seasons, which is a great waste of manpower, and manual adjustments cannot guarantee timeliness
