Safe protecting circuit for chicken house power failure and start and system

Abstract

The invention discloses a safe protecting circuit for chicken house power failure and start, and belongs to the technical field of livestock breeding. An OV terminal of a time relay and a COM terminalof the time relay are connected with an NO terminal of a phase sequence protection relay; a COM terminal of the phase sequence protection relay and an NO1 terminal of a direct-current contractor areconnected with an OV terminal of a UPS power supply; a positive electrode side of the time relay, an NO2 terminal of the direct-current contractor, an NO3 terminal of the direct-current contractor anda control terminal positive electrode of the direct-current contractor are connected with a positive electrode side of the direct-current UPS power supply; an NO terminal of the time relay is connected with a control terminal negative electrode of the direct-current contractor; an NO5 terminal of the direct-current contractor and an NO6 terminal of the direct-current contractor are connected withthe positive electrode side of a direct-current electric push rod, an OV terminal of the direct-current electric push rod is connected with an NO4 terminal of the direct-current contractor, and thenthe purpose of completely eradicating the phenomenon that due to power failure, the temperature in a chicken house is too high, chickens die is achieved.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding, and in particular relates to a safety protection circuit and system for power-off start of a chicken coop. Background technique [0002] Chicken house refers to the place where chickens live. According to the breeding objects, there are core chicken house, breeder house, brooder house, rearing house, layer house, broiler house, and environmentally safe livestock and poultry house. [0003] The traditional industrial chicken house not only has the environmental conditions suitable for the growth and development of chickens, but also should meet the requirements of mechanization, scientific management and sanitation and epidemic prevention. [0004] Chicken houses are divided according to the building structure: they are divided into closed type, window type, and open type (open type); at present, closed type chicken houses are widely used in the market, and closed type chick...
