Detailed Description
The invention will be further described in detail with reference to the following examples, which are given in the accompanying drawings.
As shown with reference to figures 1-5,
an intelligent fresh air system for an agricultural greenhouse started by memory temperature comprises a detection component 1 installed in the greenhouse and a ventilation component 2 matched with the detection component 1, wherein the detection component 1 comprises at least two detection components which are respectively positioned at the lower part and the higher part of the greenhouse, the detection component 1 comprises a memory alloy 11 with the metamorphic temperature of 35-40 ℃, a power supply 12 electrically connected with the memory alloy 11 and a contact 13 matched with the memory alloy 11 and connected with a signal emission component 6, and the signal emission component 6 is in communication connection with the ventilation component 2; when the memory alloy 11 reaches the metamorphosis temperature, the memory alloy contacts the contact 13, and the ventilation component 2 acquires a detection signal of a signal transmitting device; when the ventilation part 2 acquires the detection signals of the two signal emitting devices, the ventilation part 2 starts ventilation.
Carry out automatic ventilation through detection component 1 cooperation ventilation component 2, realize thermostatic control, in fact, ventilation component 2 can set up delay circuit, carries out the short duration through the delay effect and ventilates to cooperate the detection signal of detection component 1 to judge whether need continue to ventilate, if still have detection signal after one section lasts the end of ventilating, then continue next section and continue to ventilate this moment, until detection component 1 no longer sends detection signal. Control through delay circuit, avoid ventilation unit 2 to appear at the temperature smart boundary point and break and make repeatedly and lead to equipment operation unstable.
Specifically, the detection component 1 is controlled through the memory alloy 11, and the signal emission component 6 is matched with the ventilation component 2 to be remotely controlled, so that the assembly efficiency is improved. The on-off control of the signal is controlled through the deformation of the memory alloy 11, when the temperature of the memory alloy 11 reaches the metamorphosis temperature, the memory alloy 11 deforms, and at the moment, the power supply 12 and the contact 13 can be conducted when the deformation occurs by matching with the contact 13, so that the detection signal is generated. This effect can adjust the transformation temperature in accordance with the ratio of the internal components of the memory alloy 11. The metamorphosis alloy that this scheme adopted is 35 ~ 40 degree centigrade scope, can avoid the high temperature in heat retaining. In the optimization of this scheme, still will detect part 1 and set up respectively in low department and eminence two places position, because the carbon dioxide concentration of low department is higher, actually has the temperature difference with the eminence, can set up the memory alloy 11 that 35 degrees centigrade is metamorphosis temperature in this scheme in the relatively higher position, and 40 degrees centigrade is the memory alloy 11 setting of metamorphosis temperature in the low department, because the carbon dioxide concentration of low department is higher, can also provide carbon dioxide and promote crops to grow when possessing the heat preservation effect. Generally, the temperature difference is big round the clock winter in some areas, leads to inside high temperature easily under the sufficient condition of illumination daytime, is unfavorable for crops to grow on the contrary, can suitably cool down through foretell ventilation part 2 cooperation detection part 1 this moment to detection effect is stable, need not detect with the help of electronic sensor. Because the concentration of carbon dioxide that detection part 1 of low department is located is higher, if keep not reaching the early warning line within 40 degrees centigrade, if the temperature that detection part 1 of eminence detected reaches 35 degrees centigrade, open the ventilation, the double detection can ensure that ventilation part 2 can not be too early ventilate.
In order to maintain the content of carbon dioxide while reducing the temperature, the ventilation component 2 is connected with a ventilation pipeline 3, and the ventilation pipeline 3 is positioned at the high position outside the greenhouse; this air pipe 3's entry is connected with ventilation unit 2, exports and big-arch shelter internal connection, and when ventilation unit 2 ventilated, the ambient gas in the extraction big-arch shelter entered into air pipe 3 to return inside the big-arch shelter after cooling through air pipe 3.
Through letting air inflow air pipe 3, utilize air pipe 3 to cool down the air to air pipe 3 is located the eminence position, the air after the cooling can sink, begin to mix the cooling with original ambient gas from the inside low department of big-arch shelter, and then improve the cooling effect, and can keep carbon dioxide content, avoid the heat preservation effect to descend and lead to the effect of keeping warm at night to weaken, also avoid influencing crops growth simultaneously.
In order to increase the heat dissipation area of the ventilation duct 3 and enhance the heat dissipation effect, the ventilation duct 3 is a corrugated pipe.
In further arrangement, the ventilation duct 3 is provided with a plurality of through holes 31, and a detachable blocking plate 4 is arranged at a position corresponding to the through holes 31, and the blocking plate 4 annularly covers the outer surface of the ventilation duct 3 at a position corresponding to the through holes 31 so as to block the through holes 31.
Through set up through-hole 31 on ventilation pipe 3, can reduce carbon dioxide content when needs, through letting the carbon dioxide in the pipeline pass through-hole 31 and outside release, and then progressively reduce carbon dioxide content, for example the difference in temperature is lower round clock and when the temperature is higher, just lower to the requirement of heat preservation effect, can effectively cool down through the mode of releasing carbon dioxide. Because the high end of temperature is seasonal, consequently can be fast and effectual regulate and control temperature through the manual work to separation board 4, because manual operation's cycle is long, consequently can not frequent operation, consequently the switching of two kinds of states can be accomplished to simple structure.
In order to facilitate the installation of the blocking plate 4, a plurality of protrusions 41 are arranged on the blocking plate 4, the positions of the protrusions 41 correspond to the positions of the through holes 31, the through holes 31 are arranged on the outer surface of the ventilation duct 3 in an array manner, and when the protrusions 41 are embedded in the corresponding through holes 31, the blocking plate 4 is assembled on the ventilation duct 3; the barrier panel 4 has a spring force tending to return to a flat panel.
Through the cooperation of arch 41 and through-hole 31, can realize the shutoff to through-hole 31 when separation board 4 parcel is on air pipe 3 surface to because separation board 4 has the elasticity of recovering to the flat board, consequently when separation board 4 parcel is on air pipe 3, still just can be just by the restoring force, through the joint of arch 41 and through-hole 31 this moment, can realize the fastening, do not need operating personnel to fasten separation board 4, for example adopt the staple bolt to cramp etc..
In order to improve the release effect of carbon dioxide, an end of the through hole 31 corresponding to the inner wall of the ventilation duct 3 facing the airflow source is provided with an inclined surface 51 or an arc groove 52, and when the airflow passes through the through hole 31, part of the airflow flows out through the inclined surface 51 or the arc groove 52.
The inclined surface 51 and the arc-shaped groove can facilitate the outflow of air flow, thereby improving the release of carbon dioxide.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
