Abstract
The invention discloses a ventilation structure for an intelligent greenhouse. An air inlet mechanism comprises an air inlet pipe connected with the first end of a three-way valve. The second end of the three-way valve is connected with a third fan extending into the greenhouse, and the third end of the three-way valve is sequentially connected with a heater and a second fan extending into the greenhouse. An air inlet channel is connected with a temperature sensor. The temperature sensors, the three-way valve, the third fan and the second fan are all connected with a controller. The air inlet mechanism of the ventilation structure for the intelligent greenhouse is provided with the temperature sensor and two air inlet pipelines, when the temperature is lower than a preset threshold, the heater is started, the air inlet pipeline with heater is opened, and at this time, the temperature of inflow air is not too low and can meet the requirement; when the outside temperature is higher than the preset threshold, the other air inlet pipeline is opened and the air directly flows into the greenhouse to meet the requirement. The structure has the advantages of meeting usage requirements of users and saving energy.
Description
Technical field
The present invention relates to intelligent greenhouse technical field, more particularly to a kind of aeration structure for intelligent greenhouse.
Background technology
Continued to develop with agrotechnical, chamber planting has turned into a kind of main flow industry, it is necessary to often give greenhouse ventilation during greenhouse use, for example, plant just should be aerated hardening after emerging according to warm indoor temperature and outside air temperature situation, primarily to reducing warm indoor temperature, increase warm indoor air flows, exclude moisture, rice shoot excessive growth is prevented, is beneficial to rice shoot and is adapted to outside air temperature as early as possible, improve quality.During greenhouse ventilation, many vegetable growers are that, using unified air vent mode, east, the ventilating opening at west two set and be also just as greatly.But, greenhouse east, west two are influenceed by sunlight and external air flow, and temperature difference is very big.Especially in cold ground area, big greenhouse internal-external temperature difference is larger, and the cold air of traditional draft type is directly entered in big greenhouse, and plant can influence the growth conditions of plant due to directly contacting cold gas, greatly reduce the survival rate of plant.
The content of the invention
The purpose of the present invention is directed to technological deficiency present in prior art, and provides a kind of aeration structure for intelligent greenhouse.
To realize the purpose of the present invention, the invention provides a kind of aeration structure for intelligent greenhouse, including air inlet mechanism and air draft mechanism, the air inlet mechanism includes intake stack, the intake stack is connected with triple valve first end, the end of the triple valve second is connected with the 3rd blower fan for extending into the greenhouse, the end of the triple valve the 3rd is sequentially connected heater and extends into second blower fan in the greenhouse, temperature sensor is also associated with the air intake passage, the temperature sensor, triple valve, 3rd blower fan, second blower fan is connected with controller, the air draft mechanism includes exhaust duct and extends into first blower fan in the greenhouse, first blower fan is connected with controller.
Wherein, the air inlet mechanism is separately positioned on the opposite side in greenhouse with air draft mechanism.
Wherein, the controller is PLC.
Compared with prior art, the present invention, sets air inlet mechanism and air draft mechanism, and air inlet mechanism sets temperature sensor and two-way air inlet pipeline, when temperature is less than predetermined threshold value, start heater, open the air inlet pipeline with having heaters, now, the temperature of the air of entrance will not be too low, meets and requires；When external temperature height predetermined threshold value, an other air inlet pipeline is started, air is directly entered greenhouse, then meet and require, such structure is set, both met the use demand of user, and save energy.
Brief description of the drawings
Fig. 1 show structural representation of the invention；
In figure, the blower fans of 1- first, 2- exhaust ducts, the blower fans of 3- second, the blower fans of 4- the 3rd, 5- heaters, 6- triple valves, 7- intake stacks, 8- temperature sensors.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It should be noted that, " connection " the described herein and word for expressing " connection ", such as " be connected ", " connected ", be both directly connected to another part including a certain part, be also connected with another part by miscellaneous part including a certain part.
As shown in Figure 1, the invention provides a kind of aeration structure for intelligent greenhouse, including air inlet mechanism and air draft mechanism, the air inlet mechanism includes intake stack, the intake stack is connected with triple valve first end, the end of the triple valve second is connected with the 3rd blower fan for extending into the greenhouse, the end of the triple valve the 3rd is sequentially connected heater and extends into second blower fan in the greenhouse, temperature sensor is also associated with the air intake passage, the temperature sensor, triple valve, 3rd blower fan, second blower fan is connected with controller, the air draft mechanism includes exhaust duct and extends into first blower fan in the greenhouse, first blower fan is connected with controller.
Wherein, the air inlet mechanism is separately positioned on the opposite side in greenhouse with air draft mechanism.
Wherein, the controller is PLC.
The present invention, sets air inlet mechanism and air draft mechanism, and air inlet mechanism sets temperature sensor and two-way air inlet pipeline, when temperature is less than predetermined threshold value, start heater, open the air inlet pipeline with having heaters, now, the temperature of the air of entrance will not be too low, meets and requires；When external temperature height predetermined threshold value, an other air inlet pipeline is started, air is directly entered greenhouse, then meet and require, such structure is set, both met the use demand of user, and save energy.
When use, the signal gathered by temperature sensor, controller control air inlet mechanism selects air inlet pipeline, meanwhile, exhaust pipeline is opened in control, and intelligent, automation is greatly improved, and meets the use demand of user.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
