Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture, and particularly relates to a culture cage based on a heat pump system and its control system. Background Art

[0002] In recent years, with the development of industrial aquaculture and deep-sea and far-sea aquaculture, culture cages based on heat pump systems have gradually become an important part of modern fisheries; heat pump technology provides a stable and efficient water environment for aquaculture through precise temperature control capabilities; for example, in seawater aquaculture, heat pump equipment made of anti-corrosion materials can effectively resist seawater corrosion, extend the life of the unit, and achieve constant water temperature through an intelligent system.

[0003] For example, an aquaculture cage disclosed in the national patent publication number CN112913747B includes a servo motor driving a lead screw to rotate inside a slide plate and a support plate, and then the slide plate drives a perforated push plate to move inside the first cage. When the perforated push plate moves, a pulley slides inside a slide rail, which can reduce the resistance when the perforated push plate moves. By moving the perforated push plate, food residues in the first cage can be pushed through a conical hole into the second cage for large fish to eat.

[0004] However, the traditional device still has the following problems when in use: Since the lead screw is exposed for a long time, impurities are likely to adhere to its surface, which will then affect the meshing transmission between the lead screw and its mating structure.

The screw rod 6 rotates to drive the matching plate 15 and the filter plate 16 to move along the inner side of the net box 1 2 as a whole, and the remaining fish food in the net box 1 2 is pushed to the inside of the net box 2 3 through the closed plate formed by the filter plate 18 and the filter plate 16 through the partition 4 for the big fish to eat, so as to avoid the food deposition affecting the water quality and reduce the waste of food. When the screw rod 6 rotates to drive the matching plate 15 to move, the brush 34 cleans the outer ring surface of the screw rod 6 to prevent Because the lead screw 6 is exposed to the outside, impurities adhere to its surface, thereby affecting the subsequent meshing transmission of the lead screw 6 and the matching plate 15; when the connecting rod 32 is located at the top of the straight groove 31 by pulling the center rod 38, the electric telescopic rod 27 is started to drive the fixed plate 28 to move downward, and the linkage table 29 will also move downward, so that the linkage table 29 will pull the traction rope 40. Under the action of the counterweight block 39, the center rod 38 will tilt to the side where the traction rope 40 is fixed, and the cleaning plate 33 will also rotate 90 degrees (please refer to Figure 9 ), so that it is easy to move the scraper 35. When the scraper 35 is moved, the cleaning teeth 36 will clean the bristles 34, and the notch 37 can allow the cleaning teeth 36 to deform, so that the cleaning teeth 36 can overlap and fit with the bristles 34 to achieve the best cleaning effect.
