Abstract
An automatic temperature-controlled sky-light for green house without artificial power supply consists of mainly film-pressing hoop, static window blade and movable window blade. The opening edge of the house film is held between the film-pressing hoop and the matching surface of the static window blade, and the static window blade and the movable window blade are installed together through one shaft. Both the static window blade and the movable window have equidistant-distributed but dislocated air permeating holes, and have connected tensile springs and memory alloy tensile springes with opposite turning moment respectively. The temperature-controlled sky-light has simple structure, and can open and close automatically according to temperature change without needing electric power supply.
Description
The invention belongs to the automatic temperature controlling sky-light for green house that does not need energy operation.
At present the green house constant temperature system all disposes aircondition, and need be provided with the energy could work, local inapplicable to away from power supply, even to economy rural area preferably, and also because of its complex structure, the cost height, planting cost rises thereupon, and can not extensively popularize; Skylight temperature-controlling system complex structure manually, cost is also higher, needs people often to observe variation of temperature, and therefore field management inconvenience often cause the damage of plant species.
The purpose of this invention is to provide a kind of automatic temperature controlling sky-light for green house that need not power supply, it is simple in structure, cost is low, undergoes technological transformation, and can vary with temperature and controls open and close action automatically.
Implementation of the present invention is: mainly be made up of press mold hoop, static window leaf, active window leaf, the edge of opening of canopy film is clipped between the mating surface of press mold hoop and static window leaf, active window leaf and static window leaf are fitted together by axle, the air-vent that five equilibrium is arranged on the two, and be connected with opposite extension spring of torque and memory metal respectively between the air-vent on the active window leaf and the dislocation of static window leaf, active window leaf and static window leaf.
This skylight is according to the metal phase change principle of dynamics, and the extension spring that utilizes the SMA memory metal to make detects booth top hot air temperature, produces the moment of windowing or closing window.When booth top air themperature rose because of sunshine, the temperature that is installed in the SMA memory metal at booth top was also followed rising.Rise to the phase transition temperature T of SMA memory metal when temperature
aThe time, the SMA extension spring in mechanism will produce transformation stress shrinks extension spring, and radiant type active window leaf mechanism produces angular displacement opens the skylight.Air themperature descends in the canopy because cross-ventilated effect makes, when temperature drops to phase transition temperature T
aWhen following, the transformation stress in the SMA extension spring disappears, and under the extension spring effect of another opposing torque, radiant type active window leaf mechanism produces opposite angular displacement closes the skylight.
Below, the specific embodiment of the present invention according to Figure of description provides is further described its structure.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a side-looking structural representation of the present invention;
Fig. 3 is a press mold hoop of the present invention place partial structurtes schematic diagram.
Referring to accompanying drawing, this skylight mainly is made up of press mold hoop 1, static window leaf 2, active window leaf 3, and the edge of opening of canopy film 4 is clipped in the mating surface gap of press mold hoop 1 and static window leaf 2 (seeing Fig. 2,3), and this skylight is fixed on the booth.Active window leaf 3 is fitted together (Fig. 2) with static window leaf 2 by axle 5, the two all is discoid, active window leaf 3 is contained in the re-entrant cavity of static window leaf 2 belows, and their cooperation outward flange has relative annular groove 6, and annular groove forms the inside and outside aeroseal (Fig. 3) of canopy herein.The radial fan-shaped air-vent 7 that five equilibrium is arranged on active window leaf 3 and the static window leaf 2, and in off position the time, the air-vent 7 on the active window leaf 3 and the mutual dislocation of static window leaf 2, when open, 7 (see figure 1)s that coincide together of air-vent.Depart from its axle center on the active window leaf 3 and locate a hinged connecting lever 8, the two ends of connecting lever 8 are connecting a extension spring 9 that phosphor bronze makes and an end of memory metal 10 respectively.The other end of this two extension spring 9,10 is connected on the static window leaf 3, phase countershaft 5 forms opposite torque (Fig. 1), when temperature is higher than phase transition temperature, memory metal 10 shrinks, and the extension spring 9 of phosphor bronze has heat deformability and elasticity preferably, produces necessarily elongation, the rotating torque that memory metal 10 produces is bigger, so window is open, when temperature was lower than phase transition temperature, then action was opposite.Sleet umbrella 11 is equipped with in static window leaf 2 tops, can avoid rain, snow to the erosion of this window motion, simultaneously also and avoid burning sun that the direct irradiation of memory metal 10 is produced misoperation.The phase transition temperature of memory metal 10 can be adjusted in 20～40 ℃ by manufacturer according to the actual needs of plant, and also can adorn micrometer adjusting screw on the motion of this window, does to adjust among a small circle near phase transition temperature.
From technique scheme of the present invention, it is in light weight that this window and traditional electric control temperature skylight relatively have, body Long-pending little, small investment, Non-energy-consumption is easily popularized, and is easy for installation, and the advantages such as long service life are in fact one and suit The booth temperature adjustment skylight of China's national situation.
