Problems solved by technology

In the fishponds in gardens, freshwater fish are commonly seen, and the ornamental value of freshwater fish is far less than that of tropical fish, and the cultivation of tropical fish is relatively difficult, and the water temperature needs to be controlled, and the water temperature controller in the prior art usually adopts manual control. With monitoring, the workload is heavy, which is not conducive to promotion

Abstract

The invention discloses an automatic temperature controller for a tropical fish culture pond in a garden. The automatic temperature controller comprises a heating rod, a direct current power supply, a temperature sensor, a first operational amplifier, a second operational amplifier, first to tenth resistors, a first potentiometer, a second potentiometer, a first diode, a second diode, a field-effect tube and a relay. The temperature sensor is adopted as a temperature control device, and outputs different signal voltages at different water temperatures, signals are amplified by the operational amplifies, and the amplified drive voltage controls the field-effect tube, so that the control end of the relay controls the temperature rising of the heating rod. Compared with the prior art, the automatic temperature controller can control the water temperature automatically according to the water temperature in a fishpond, keeps the water temperature in the control range, is free from manual control, reduces workload, realizes intelligent control, and has popularization and use values.

Description

【Technical field】 [0001] The invention relates to an auxiliary device for cultivating tropical fish in gardens, in particular to an automatic temperature controller for cultivating ponds for tropical fish in gardens. 【Background technique】 [0002] The garden style is a beautiful natural environment and recreation created by using engineering technology and artistic means in a certain area, by transforming the terrain (or further building mountains, stacking stones, and water management), planting trees and flowers, building buildings, and arranging garden roads. The realm is called a garden. It is unique in Chinese Han architecture, and the one with great achievements is the classical garden architecture. In the fishponds in gardens, freshwater fish are commonly seen, and the ornamental value of freshwater fish is far less than that of tropical fish, and the cultivation of tropical fish is relatively difficult, and the water temperature needs to be controlled, and the wate...
