On the market manual film-coiling device and electronic film-coiling device are arranged now, but also need manually to operate, indoorly do not reach desirable temperature, fruits and vegetables can better normal growth.Temperature and humidity in the greenhouse is a very large difficult problem, and we discharge temperature and humidity by the mode that ventilating fan is installed in a side in greenhouse, and low temperature and high relative humidity and the hot and humid disease that causes just can control to minimum like this.
The utility model content
In view of above-mentioned, the utility model will provide a kind of daylight full-automatic temperature-controlling equipment, and it can regulate the temperature in the greenhouse automatically.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of daylight full-automatic temperature-controlling equipment, comprise the greenhouse by solar heat that constitutes by the hyaline membrane that covers outside frame and the frame, electronic film-coiling device is housed on the end face of greenhouse by solar heat, one side of greenhouse by solar heat is installed ventilating fan, electronic film-coiling device and ventilating fan are controlled by automatic temperature control circuit, this automatic temperature control circuit comprises first temperature sensor, first temperature controller, second temperature sensor, second temperature controller, forward and reverse controller, wherein:
The output of first temperature sensor connects the input of first temperature controller, the break-make of first temperature controller control electrical machinery of ventilator;
The output of second temperature sensor connects the input of second temperature controller, and second temperature controller is controlled the break-make of forward and reverse controller;
Forward and reverse controller is serially connected in the electric power loop of electronic film-coiling device.
Further: described forward and reverse controller is to have two pairs of normally closed nodes and two pairs of relays of often opening node, and its normally closed node and Chang Kai node are respectively with electronic film-coiling device forward with oppositely insert in the electric power loop of electronic film-coiling device.
Further: being connected in series respectively in the forward of described electronic film-coiling device and the reverse electrical source loop is just changeing time timer and reversing time timer.
When the temperature in the daylight greenhouse is higher than the temperature of setting, automatic temperature control circuit will start ventilating fan and/or make electronic film-coiling device volume film, realize ventilating, make the temperature and humidity in the greenhouse by solar heat descend, otherwise, then close ventilating fan and/or electronic film-coiling device is put film, make that the temperature in the greenhouse by solar heat rises, thereby regulate the temperature in the greenhouse by solar heat automatically, make it the temperature that keeps desirable.
Automatic temperature control circuit the utlity model has following advantage: owing to can remain on the temperature in the greenhouse by solar heat desirable temperature, prevent that temperature is fluctuated, so can reduce the generation of fruits and vegetables damage by disease and insect, alleviate the agricultural chemicals spending, increase carbonic acid gas in indoor concentration, the saving of labor, save time, laborsaving, be peasant's increasing both production and income support that provides the necessary technical.
With the strawberry is example, can reduce behind employing the utility model to rot the fruit rate more than 70%, and output increases more than 8%, can reduce pesticide dosage in addition, so that the residue of pesticide of fruits and vegetables still less, guarantees that the common people are able to eat relieved fruits and vegetables.
Description of drawings
Fig. 1 is automatic temperature control circuit figure of the present utility model;
Fig. 2 is the circuit diagram of forward and reverse controller.
Embodiment
Be described further below in conjunction with accompanying drawing.
The utility model is a kind of daylight full-automatic temperature-controlling equipment, comprise the greenhouse by solar heat that constitutes by the hyaline membrane that covers outside frame and the frame, electronic film-coiling device is housed on the end face of greenhouse by solar heat, and a side of greenhouse by solar heat is installed ventilating fan, and electronic film-coiling device and ventilating fan are controlled by automatic temperature control circuit.
As shown in Figure 1, this automatic temperature control circuit comprises the first temperature sensor R1, the first temperature controller T1, the second temperature sensor R2, the second temperature controller T2, forward and reverse controller A.K1 is the power switch of automatic temperature control circuit.Wherein:
