Description
Technical field
The utility model relates to a kind of livestock breeding facility, especially can control the pig house temperature automatically and can not send the visible light unlikely heating installation that is bitten by pig again.
Background technology
Many pig houses all use powerful incandescent lamp to shine to allow pig heating, result can make pig be subjected to unnecessary illumination and too high temperature factor influence; And sell on the market now, also the exothermal infrared blanket of some pig-breeding family use is easily bitten bad by pig again.So a kind of pig house heating installation need be arranged at present, allow people can control the pig house temperature automatically but can not make pig be subjected to unnecessary illumination and the influence of too high temperature factor, simultaneously also can be by the pig destruction that bites.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, economical and practical temperature-control pigsty heating installation, the pig house temperature can be controlled automatically but can not make pig be subjected to unnecessary illumination and the influence of too high temperature factor, can also avoid suffering simultaneously the destruction that bites of pig.
The purpose of this utility model is achieved through the following technical solutions: it is by transformer, the rectifier bridge heap, filter capacitor, adjustable resistance, temperature sensor, fixed resistance, triode, relay, heating installation is formed, it is characterized in that: the secondary coil of transformer connects the rectifier bridge heap, be connected in series variable resistance successively behind one end of the positive polarity termination filter capacitor of rectifier bridge heap, one end of temperature sensor and fixed resistance, connect the base stage of triode between temperature sensor and the fixed resistance, the radiation utmost point of this triode connects the other end of described fixed resistance, connect the other end of described filter capacitor and the negative polarity end of rectifier bridge heap behind the collector series relay coil of this triode, the negative polarity end ground connection of rectifier bridge heap; The rectifier bridge heap is positive polarity rectifier bridge heap, and the secondary coil of transformer can be exported 12V voltage, and triode is NPN transistor, and temperature sensor is NTC type thermistor; Above-described transformer, rectifier bridge heap, filter capacitor, adjustable resistance, temperature sensor, fixed resistance, triode and relay are all concentrated to be welded on the circuit board; Terminals of the normally-closed contact of relay are drawn the back with lead and are connected with heating installation, connect an end of transformer again, connect an end of transformer after another terminals of the normally-closed contact of relay are drawn with lead; Described heating installation adopts the infrared heating lamp that can send black light.
The beneficial effects of the utility model are, are conducive to be the growing and breed the environment that provides good of live pig, realize energy-saving and emission-reduction; Simultaneously with low cost, simple in structure, economy and durability, market capacity is big, has sizable promotional value.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
1 transformer among the figure, 2. rectifier bridge heap, 3. filter capacitor, 4. adjustable resistance, 5. temperature sensor, 6. fixed resistance, 7. triode, 8. relay, 9. heating installation.
Embodiment
In Fig. 1, transformer (1), rectifier bridge heap (2), filter capacitor (3), adjustable resistance (4), temperature sensor (5), fixed resistance (6), triode (7), relay (8) and heating installation (9) have constituted the utility model.The secondary coil of transformer (1) connects rectifier bridge heap (2), the adjustable resistance (4) of connecting successively behind one end of the positive polarity termination filter capacitor (3) of rectifier bridge heap (2), one end of temperature sensor (5) and fixed resistance (6), connect the base stage of triode (7) between temperature sensor (5) and the fixed resistance (6), the radiation utmost point of this triode (7) connects the other end of described fixed resistance (6), connect the other end of described filter capacitor (3) and the negative polarity end of rectifier bridge heap (2) behind collector series relay (8) coil of this triode (7), the negative polarity end ground connection of rectifier bridge heap (2); Rectifier bridge heap (2) is positive polarity rectifier bridge heap, and the secondary coil of transformer (1) can be exported 12V voltage, and triode (7) is NPN transistor, and temperature sensor (5) is NTC type thermistor; Above-described transformer (1), rectifier bridge heap (2), filter capacitor (3), adjustable resistance (4), temperature sensor (5), fixed resistance (6), triode (7) and relay (8) are all concentrated to be welded on the circuit board; Terminals of the normally-closed contact of relay (8) are drawn the back with lead and are connected with heating installation (9), connect an end of transformer (1) primary coil again, connect an end of transformer (1) primary coil after another terminals of the normally-closed contact of relay (8) are drawn with lead.Like this, inferior cascade rectifier bridge heap (2) and the filter capacitor (3) of transformer (1), connect the triode bias pressure circuit that forms with adjustable resistance (4), temperature sensor (5), fixed resistance (6) and triode (7) again, described triode bias pressure circuit and relay (8) are formed temperature detect switch (TDS), and relay (8) normally-closed contact terminals are derived the back with lead and linked to each other with heating installation (9).The resistance that regulates adjustable resistance (4) can make triode (7) in temperature sensor (5) conducting and make relay (8) adhesive when being in a certain temperature value.When environmental temperature became big, NTC thermistor resistance diminished thereupon.The voltage of fixed resistance (6) raises, when reaching the triggering and conducting voltage of triode (7), triode (7) conducting, electric current flows through the coil of relay (8), relay (8) gets electronic work, cut off the power supply circuits of heating installation (9), so that the pig house temperature is controlled automatically and can not made pig be subjected to too high temperature effect.And when environmental temperature diminished, NTC thermistor resistance became big thereupon.The voltage of fixed resistance (6) reduces, and when not reaching the triggering and conducting voltage of triode (7), triode (7) ends, and electric current does not flow through the coil of relay (8), and the power supply circuits of heating installation (9) are recovered as a result.Described heating installation (9) adopts the infrared heating lamp can send black light, is placed in the pig house not the place that can be touched by pig, has both avoided making pig to be subjected to unnecessary illumination effect, can also avoid suffering simultaneously the destruction that bites of pig.
