Detailed Description
The invention is further described with reference to the following figures and detailed description.
Example 1: as shown in figures 1 to 7 of the drawings,
a ventilation rainproof intelligent building comprises
The building comprises a building body, wherein the building body comprises a plurality of floors, and a vent hole 11 and an adjustable ventilation window structure are arranged on a wall body 1 of each floor; on each floor:
the adjustable ventilating window structure comprises a round window plate 2 used for shielding a ventilating hole, a rotating shaft 21 coaxially connected with the round window plate, a plate through hole 22 formed in the round window plate, a balancing weight 3 formed in the round window plate and a water storage device formed in the round window plate, wherein the water storage device comprises a transverse hanging shaft 41 rotatably connected with the round window plate, a vertical connecting rod 42 connected with the transverse hanging shaft and a water storage tank 43 fixed at the lower end of the vertical connecting rod, the upper end of the water storage tank is opened, a slow drainage hole is formed in the bottom of the water storage tank, the aperture of the slow drainage hole is 10-50 mm, the rotating shaft is rotatably connected with a wall body of a building, and the balancing weight is fixed to the bottom of the;
when the water storage tank, the rotating shaft and the balancing weight are sequentially arranged from top to bottom, the plate through hole is coaxial with the vent hole;
when the water storage tank, the rotating shaft and the balancing weight are sequentially arranged from bottom to top, the ventilation hole is completely staggered with the plate through hole, and the circular window plate shields the ventilation hole;
when the water storage tank is empty and the water storage tank, the rotating shaft and the balancing weight are sequentially arranged from top to bottom, the gravity center of the adjustable ventilation window is lower than the lowest point of the rotating shaft;
when the water amount in the water storage tank is greater than one fourth of the volume of the water storage tank and the water storage tank, the rotating shaft and the balancing weight are sequentially arranged from bottom to top, the gravity center of the adjustable ventilation window is lower than the lowest point of the rotating shaft.
Under one atmosphere, after the water storage tank is filled with purified water, the time for naturally draining the purified water in the water storage tank through the slow drain hole is 0.5 to 3 minutes (although impurities exist in rainwater, the drainage effect and the drainage time are basically the same as those of the purified water, the purified water is taken as a reference to ensure the accuracy of expression, in practice, the drainage time is not strict, only a certain time is required for draining the water, and the definition of 'draining the water' is not thorough, and in practice, a small amount of residue does not influence the normal work of the invention). The aperture of the slow drain hole is 10 mm to 50 mm, so that the water storage (rainwater storage) speed of the water storage tank is higher than the drainage (rainwater drainage) speed of the rain drainage hole even if the rain is small.
When there is no water or little water in the reservoir (the volume of water in the reservoir is less than one fourth of the volume of the reservoir), the present invention remains in the state of fig. 2, and at this time, normal natural ventilation (natural wind circulation, ventilation realization) is performed in the floor. When the back rains, the water yield is greater than water storage tank volumetric quarter in the water storage tank, because the whole focus of circle window board department shifts, as long as take place any and rock or shake, the pivot will rotate to finally reach "water storage tank, pivot and balancing weight and arrange" this state in proper order by supreme down ", this moment, the ventilation hole staggers completely with the board through-hole, and the ventilation hole has been sheltered from to the round window board, can avoid the rainwater to get into in the floor along with the wind.
After the rain stops, the rainwater in the water storage tank is gradually discharged and drained, and the whole gravity center at the round window plate is transferred and reset again, so that all the structures are automatically reset.
The water storage tank is provided with a filter screen plate 5 covering the opening of the water storage tank, and the aperture of the mesh of the filter screen plate is smaller than that of the slow drain hole. The number of meshes of the screen plate is 50 to 200. The filter screen plate can prevent large-volume impurities from entering the water storage tank, and the mesh aperture of the filter screen plate is smaller than that of the slow drain hole, so that even small-volume impurities enter the water storage tank, the small-volume impurities can be smoothly discharged from the slow drain hole.
The axis of the rotating shaft is horizontal, the axis of the ventilation hole is horizontal, and the round window plate is positioned between the water storage tank and the building body.
On each floor: be equipped with exhaust pipe 6 on the wall body of floor, the exhaust pipe includes horizontal pipe section 61 and standpipe section 62, horizontal pipe section one end and the inside intercommunication of floor, horizontal pipe section other end and standpipe section upper end intercommunication. The air flow path of the exhaust air pipe, namely the horizontal pipe section for air intake and the vertical pipe section for downward air exhaust, ensures the smoothness of air flow circulation, and can not cause rainwater to enter the floor from the exhaust pipe.
The adjustable ventilating window structure also comprises an inflatable sealing ring 23 which is used for sealing and contacting the round window plate, the inflatable sealing ring is fixed on the wall body of the floor, the rotating shaft is rotatably connected with the wall body of the floor through a main bearing 12, a mounting hole 13 is arranged on the wall body of the floor, the main bearing is fixed in the mounting hole, one end of the rotating shaft is arranged in the mounting hole, an elastic air bag 14 which is arranged below the rotating shaft is arranged in the mounting hole, the elastic air bag is communicated with the inflatable sealing ring through an air pipe, the bottom of the elastic air bag is fixed with the wall body, when the water storage tank is empty, and when the water storage tank, the rotating shaft and the balancing weight are sequentially arranged from top to bottom, a pressing block 211 used for extruding the elastic air bag is arranged on the rotating shaft, the axis of the rotating shaft is located between the pressing block and the elastic air bag, the aperture of the central hole of the inflatable sealing ring is larger than that of the vent hole, the aperture of the central hole of the inflatable sealing ring is larger than that of the plate through hole, and the inflatable sealing ring is coaxial with.
When the water in the water storage tank is not available or is low (the water in the water storage tank is less than one fourth of the volume of the water storage tank), the invention is maintained in the state shown in figures 2 and 3, and a gap is formed between the sealing ring and the round window plate or the contact is not tight. When the back rains, the water yield is greater than in the retaining jar when the volumetric quarter of retaining jar, because the whole focus of circle luffer board department shifts, as long as take place any and rock or shake, the pivot will rotate, and finally reach "retaining jar, pivot and balancing weight arrange" this state in proper order by supreme down, "this state because the pivot also drives the briquetting and rotates together, briquetting extrusion elastic airbag, partly gaseous entering inflatable seal circle in the elastic airbag, inflatable seal circle further bloated and sealing contact, compress tightly circle luffer board, thereby can thoroughly avoid wind and rain to get into inside the floor.
Example 2: based on example 1, as shown in fig. 8,
the adjustable ventilation window structure further comprises an anti-wind pipe 15 fixed on the wall body of the floor, the axis of the anti-wind pipe is horizontal, and the round window plate is located in the anti-wind pipe. In embodiment 1, if there is wind perpendicular to the rotating shaft and the wind force is large, the round window plate may start to shake (rotate around the rotating shaft back and forth or out of order) due to the influence of the large wind, so that wind and rain may enter the floor.
