Abstract
The utility model discloses an automatic air ventilation device of a greenhouse. The automatic air ventilation device of the greenhouse is provided with a temperature sensing probe which is filled with thermal expansion liquid inside, and a hydraulic actuator which is communicated with the temperature sensing probe through a capillary tube. The lower portion of the hydraulic actuator is connected with a pulling rod, a rotating shaft is arranged in the middle of the pulling rod, and the front end of the pulling rod is connected with a pulling rope of a ventilation widow of the greenhouse. When the temperature rises, the thermal expansion liquid inside the temperature sensing probe expands by heat, a transmission shaft of the hydraulic actuator is pushed through the capillary tube to extend out to push the pulling rod to rotate around the rotating shaft, and the pulling rope is driven to open the ventilation window. When the temperature lowers, the thermal expansion liquid in the temperature sensing probe contracts by coldness, the liquid entering the hydraulic actuator flows back into the temperature sensing probe through the capillary tube, the transmission shaft of the hydraulic actuator is taken back, the pulling rod is driven to reset, and the ventilation window is closed.

Technical field
The utility model relates to a kind of green house automatic discharging device, relates in particular to a kind of self-operated type temperature sensing liquid and presses wind apparatus.
Background technology
Existing booth automatic discharging device, usually all need external power supply, comprise complicated temperature sensor, temperature signal processor and accordingly by the motor-driven mechanical transmission mechanism, in the course of work of whole device, need the larger electric energy of consumption rate, and because complex structure, holistic cost is higher.And the simple and easy window that leaks informaton (dragline type) of traditional green house, can not use above-mentioned discharging device, need to reequip to green house the window that leaks informaton of equipped specialized structure.
The utility model content
The utility model is for the proposition of above problem, and a kind of green house automatic discharging device of development, have: its inside is loaded with the temperature-sensing probe of thermally-expansible liquid, and hydraulic actuator, this hydraulic actuator are communicated with described temperature-sensing probe by capillary;
The below of described hydraulic actuator is connected with a pull lever, and the middle part of this pull lever has a rotating shaft, and described pull lever front end is connected with the stay cord of green house vent;
When temperature raises, the thermally-expansible liquid expanded by heating in the described temperature-sensing probe, through described capillary hydraulic pressure actuator, the power transmission shaft that promotes hydraulic actuator stretches out the described pull lever of promotion and rotates around rotating shaft, drives stay cord and opens vent;
When temperature reduces, contractions of catching a cold of the thermally-expansible liquid in the described temperature-sensing probe, the liquid that enters described hydraulic actuator is back in the temperature-sensing probe through capillary, and the power transmission shaft withdrawal of hydraulic actuator drives described pull lever and resets, and closes vent.
Described hydraulic actuator below is provided with heat insulation that is positioned at outside the described power transmission shaft successively, is provided with the attaching nut below heat insulation; Be provided with back-moving spring outside described power transmission shaft is positioned at heat insulation one section, the upper end of this back-moving spring is fixedly connected with the lower surface of described hydraulic actuator.
The upper end of described hydraulic actuator is provided with the thermoregulation knob that is connected with described capillary.
Owing to having adopted technique scheme, the green house automatic discharging device that the utility model provides, this of open and close by increasing self-supporting temperature control vent processed cleverly mode frees the peasant from booth, save greatly and reduce labor cost.And whole apparatus structure is simple, technology maturation, and cost is relatively cheap, does not rely on external power supply simultaneously, and is safe and reliable, and failure rate is low extremely is suitable for promoting on a large scale and using.
Description of drawings

Embodiment
For the purpose, technical scheme and the advantage that make embodiment of the present utility model is clearer, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is known complete description:
As shown in Figure 1:
A kind of green house automatic discharging device can be realized the variation according to environmental temperature, adjusts at any time the opening and closing of green house vent, and the angle of opening.Device mainly comprises:
Inside is loaded with the temperature-sensing probe 1 of thermally-expansible liquid, and the volume of inner thermally-expansible liquid changes with the variation of environmental temperature, utilizes heated liquid to expand and automatically adjusting of the incompressible principle realization of liquid.Expansion of liquids in the temperature sensor is uniformly, and its control action is that ratio is regulated, and can realize at vent opening angle corresponding to different temperature.
This temperature-sensing probe 1 is communicated with a hydraulic actuator 5 by a capillary 2, the hydraulic drive axle 7 of hydraulic actuator 5 is connected with an end of a pull lever 9, this pull lever 9 as shown in Figure 1, the middle part is provided with a rotating shaft 10, pull lever 9 is under the promotion of hydraulic drive axle 7, centered by rotating shaft 10, carry out the rotation of limited angle, the other end of pull lever 9 is connected with the stay cord of vent, can control the opening and closing of vent, and the angle of opening, temperature is higher, liquid volume is larger, and the distance that hydraulic actuator 5 power transmission shafts press down is longer, and the angle of the unlatching of vent is also just larger.
Further, as a better embodiment, described hydraulic actuator 5 belows are provided with heat insulation 6 that is positioned at described power transmission shaft 7 outsides, below heat insulation 6, be provided with the attaching nut, be provided with back-moving spring 71 outside described power transmission shaft 7 is positioned at heat insulation 6 one section, the upper end of this back-moving spring 71 is fixedly connected with the lower surface of described hydraulic actuator 5.
Further, for the convenient unlatching threshold temperature of setting described vent, as a better embodiment, the upper end of described hydraulic actuator 5 is provided with the thermoregulation knob 3 that is connected with described capillary 2.For example when thermoregulation knob is set in 30 ℃, the temperature that perceives when temperature-sensing probe 1 is during greater than 30 ℃, pull lever 9 setting in motions, and when temperature was lower than 30 ℃, pull lever 9 set back and puts.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
