Aquaculture tank

Abstract

The invention discloses an aquaculture tank. The aquaculture tank comprises a floating platform, net cages, a sundries blocking apparatus, a feeding apparatus and a control module, wherein a through hole is formed at the plane center of the floating platform, the through hole divides the floating platform into at least two aquaculture units with equal areas, the net cages are arranged in the aquaculture units, each net cage comprises a frame body with a cuboid structure and a net arranged on the sides and bottom of the frame body, the sundries blocking apparatus is arranged ahead the net cages, the sundries blocking apparatus comprises a circular rod vertically arranged right ahead the net cages and left guide rods and right guide rods arranged on the circular rod in pairs, the feeding apparatus comprises a sealed feed storage cavity, a pressurizer, a feed conveying pipe, nozzles and quantitative valves, the control module comprises a controller, water flow sensors and pressure sensors, the water flow sensors are arranged on the side walls of the net cages, the pressure sensors are arranged on the nozzles, the controller is connected with an electric telescopic rod and controls theelectric telescopic rod according to water flow velocity signals, and the controller is connected with the quantitative valves and controls the opening and closing of the quantitative valves according to pressure signals of the pressure sensors.

Description

technical field [0001] The invention relates to the field of aquaculture equipment, and more specifically, the invention relates to an aquaculture tank. Background technique [0002] It has become a relatively common way to use breeding boxes to cultivate aquatic products such as fish and shrimp. The breeding boxes can be placed in rivers, lakes or oceans for more flexible farming. The breeding box farming has the advantages of small space occupation and reasonable use of natural resources. The advantages of easy resources, feeding and salvage are deeply loved by farmers. [0003] The structure of existing breeding box is comparatively simple, usually on the basis of building the floating platform, a plurality of net cages are set on the floating platform, and the net cages stretch into the water to provide the space for breeding, and the water entry depth of the net cages is generally set higher.

Problems solved by technology

[0003] The structure of existing breeding box is comparatively simple, usually on the basis of building the floating platform, a plurality of net cages are set on the floating platform, and the net cages stretch into the water to provide the space for breeding, and the water entry depth of the net cages is generally set higher. Deep, because the water temperature changes greatly in the shallower position, and the ground noise is loud, which is not conducive to the growth of aquatic products. The upper part of the cage is generally set open to facilitate feeding.

There are several problems in such a breeding box: firstly, the water entry depth of the net cage is set at a relatively deep position from the beginning and is fixed and cannot be adjusted. We know that the deeper the net cage enters the water, the greater the impact of the water flow. When the water flow becomes stronger due to rain or other reasons, the cage will become unstable due to strong impact and even the structure will be destroyed, resulting in the loss of aquatic products; secondly, the current feeding method is to directly put the feed into the cage , the feed that is not eaten by the fish will directly sink to the bottom of the water or be washed away by the water flow, resulting in a waste of feed; in addition, the net cages stretched into the water are easily cut by the branches and plates brought by the water flow, and the aquatic products are from broken Hole escapes, causing damage
