The material of recuperation layer 13 is heat-storing material, and the material of cover plate 11 is light transmissive material, can be good from glass, translucency Film, the cover plate 11 positioned at upper strata and be located at lower floor recuperation layer 13 between supported by support 12, thermal-arrest canopy 1 enters from periphery Mouth is inclined upwardly to inside outlet, and formation is horn-like, and that is, cover plate 11 and recuperation layer 13 form trumpet-shaped diversion cavity, diversion cavity bag Include horizontal segment and changeover portion, horizontal segment connects into trumpet-shaped diversion cavity with changeover portion, and the runner of changeover portion is from the bottom up gradually Narrow, the both sides of changeover portion are designed using the method that hydrodynamics seeks streamline.The upper port of changeover portion is connected with the lower port of chimney 3 Logical, after thermal current is flowed out by the outlet that the entrance of horizontal segment flows into through changeover portion, enter chimney 3.
Turbine 2 is axial-flow type pressure stage turbogenerator, and turbine 2 is arranged at the export center of changeover portion, such as Fig. 1 With shown in Fig. 3, turbine 2 is provided with 6 turbine wheels 21, leaves space between turbine wheel 21 and chimney wall, is installing When, turbine hub 22 and chimney 3 center overlapping of axles, so that the Pivot axle of turbine 2 and chimney 3 center overlapping of axles.
Wind energy conversion system 4 is H type vertical axis aerogenerator, and as depicted in figs. 1 and 2, wind energy conversion system 4 includes central principal axis 41, wind Power machine blade 42, connecting rod 43 and wind turbine power generation group 44, the center line of central principal axis 41 is overlapped with chimney 3 center line, center master Axle 41 is extended through stator 45 and is fixed with chimney wall to the inside of chimney 3, and stator 45 has guide functions, and wind energy conversion system 4 includes 5 wind-force Machine blade 42, along the distribution of central principal axis 41 even circumferential, the radius of turn of pneumatic equipment bladess 42 is identical with chimney 3 radius, connecting rod 43 are rigidly connected with pneumatic equipment bladess 42, and wind turbine power generation group 44 is arranged on the lower end of central principal axis 41.
Ventilation blower 5 is axial fan, and ventilation blower 5 includes ventilating vane 51 and ventilator hub 52, wheel of divulging information The lower end of the centrally disposed main shaft 41 of hub 52, wind turbine power generation group 44 is placed in ventilator hub 52, ventilator hub 52 with Central principal axis 41 is wholely set；Ventilating vane 51 quantity is 5, and ventilating vane 51 and pneumatic equipment bladess 42 correspond just Property connect, simultaneously as the connecting rod of pneumatic equipment bladess 42 lower end, so that ventilating vane 51 is rotated together with pneumatic equipment bladess 42.
The operation principle of the utility model TRT is that outside air flows into thermal-arrest canopy 1 through thermal-arrest canopy import.White My god, thermal-arrest canopy 1 bottom recuperation layer 13 absorbs solar radiation, and temperature significantly raises, and the air-flow flowing into thermal-arrest canopy 1 is very high with temperature Recuperation layer 13 carries out heat convection, so that the temperature of air-flow is also gradually increasing.Because the radius of thermal-arrest canopy 1 is larger, air-flow has relatively The long heat time.Raise with gas flow temperature, the density of air-flow declines, and the flow velocity of air-flow also can be accelerated therewith, make extraneous sky Gas quickly continuously supplements through thermal-arrest canopy import.To evening, because recuperation layer 13 has very strong insulating power, still Can guarantee that continuing to run with of device.Due to the presence of tall and big hollow cylinder chimney 3, tall and big chimney 3 can produce chimney effect Should, form larger relative pressure in the bottom of chimney 3, therefore thermal current can produce obvious pressure drop after entering changeover portion.Again Drastically narrow plus both sides airflow path in changeover portion, make the speed of air-flow have apparent increasing, export (i.e. cigarette in changeover portion Chimney import) speed of place's thermal current and pressure drop all reach a larger value, so arrange axial-flow type pressure stage turbine herein Machine 2.Ascending air promotes the blade rotation of turbine 2, and drives the corresponding generator of turbine 2 to be generated electricity.
The thermal current flowing through turbine 2 continues on chimney 5 and rises, and in uphill process, the temperature of air-flow is gradually lowered, enthalpy Fall transforms into gravitional force, and the speed of air-flow is slightly decreased.Then air-flow flows in axial fan 5, ventilation by axial flow fan The outside Accelerating Removal air-flow of machine 5.
Because high aerial wind speed is larger, high-altitude natural wind promotes the wind energy conversion system of the H type vertical axis windmill 4 of chimney 3 top Blade 42 rotates, and drives corresponding wind-power electricity generation group 44 to be generated electricity.
Because the pneumatic equipment bladess 42 of H type vertical axis windmill 4 are rigidly connected with the ventilating vane 51 of ventilation blower 5, Ventilating vane 51 is driven to rotate so that ventilation blower 5 normal work together during pneumatic equipment bladess 42 rotation.Normal in ventilation blower 5 During work can outside Accelerating Removal air-flow, so that the air pressure within chimney 3 is declined, be internally formed bigger negative pressure in chimney 3, make The power output obtaining turbogenerator 2 is greatly improved.
