Aeration device for aquaculture

Abstract

The invention discloses an oxygen increasing device for aquaculture. The device comprises a breeding pool composed of a breeding dam with the trapezoidal section and a pool bottom with the edge sinking towards the center, a supporting frame covers the outer portion of the breeding pool, and a controller is arranged on the breeding dam; a water quality detector is arranged on the side wall of the bottom of the breeding dam, a sewage draining device is arranged at the pool bottom, and the sewage draining device comprises a sewage draining passage; the portion above the sewage draining passage isconnected with a spherical cover through a compression spring, a supporting rod is arranged at the bottom of the spherical cover and located in the sewage draining passage, and a magnetic block is arranged at the bottom of the supporting rod; a stand rod is arranged on the inner wall of the sewage draining passage and located below the supporting rod, and an electromagnet corresponding to the magnetic block is arranged on the stand rod. The device achieves full-ecological breeding, breeding water can be recycled, water draining and releasing can be intelligently and synchronously conducted, the dissolved oxygen in breeding water can be increased, and the survival rate of various aquatic products is improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aeration device for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. Generally, it includes the whole process of cultivating aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture has methods such as extensive cultivation, intensive cultivation and high-density intensive cultivation. Extensive cultivation refers to small and medium-sized Seeds are placed in natural waters, and aquatic products are grown entirely on natural bait, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas, etc. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as fish...

AI Technical Summary

Problems solved by technology

[0003] However, when a variety of aquatic animals are cultured artificially, they all face differences between the breeding environment and their natural growth environment, such as dissolved oxygen, etc., compared with their natural growth environment, which affects the success rate and quality of breeding. Dissolved oxygen and other factors, if the breeding density of aquatic animals is increased, water quality deterioration, insufficient dissolved oxygen, and frequent occurrence of diseases will occur. Therefore, the breeding density of aquatic animals is also very limited, so it is necessary to increase the breeding area. Requires high cost of farming equipment and labor costs
