Intelligent cooling system for aquaculture pond

Abstract

The invention discloses an intelligent cooling system for an aquaculture pond. The intelligent cooling system comprises support piles, a top curtain bracket, a top net curtain, a lower curtain bracket, a lower net curtain, a plurality of water distribution pipes, a filtering device and an automatic temperature control spraying system, wherein the support piles are arranged on pond ridges on the periphery of the aquaculture pond; the top curtain bracket and the lower curtain bracket are successively supported and covered on the water surface of the pond through the support piles; the top net curtain and the lower net curtain are respectively paved on the top curtain bracket and the lower curtain bracket; the water distribution pipes are arranged under the top curtain bracket; a plurality of spray nozzles are arranged on the horizontal sections of the water distribution pipes; the spray nozzles are used for spraying under the effect of the power supplied by high-pressure pumps arranged at water supply ends of the water distribution pipes; the high-pressure pumps are arranged in the filtering device. In high-temperature season, the system provided by the invention can control the water temperature at 25-28 DEG C, the water temperature difference between upper and lower layers is less than 1 DEG C, the average value of dissolved oxygen of the upper and lower layer water is maintained above 4mg/L and the excellent ecological environment is created for oviposition, oogenesis and incubation of crayfish.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to an intelligent cooling system for aquaculture ponds, in particular to an intelligent cooling system for shrimp and crab aquaculture ponds. Background technique [0002] The high temperature in summer is conducive to the growth of aquatic animals, but it is also a key season with frequent diseases, high mortality and difficult management. Moreover, excessively high water temperature in summer can easily lead to low oxygen and poor water quality in the culture pond for a long time. The water body is stratified due to temperature difference, and the dissolved oxygen in the bottom low-temperature water is low; the food intake of aquatic animals decreases, the digestion and absorption rate decreases, and the growth rate slows down. , the ability to resist stress is reduced, and the growth and molting of shrimp and crabs are also affected. The suitable spawning and hatching water temperature ...

Problems solved by technology

However, the cooling structure is complicated and the input cost is high, so it is not suitable for large-scale application

Chinese patent application (publication number CN 103478007 A) discloses a ventilation structure for symbiotic aquaculture, which can use natural ground cooling and heat to achieve heating and cooling purposes, but the ventilation structure needs to build walls and tops, which is not suitable for pond aquaculture
