Component shown in figure and corresponding mark: lifting air port 10, protector 11, guide rail 20, screw mandrel 21, nut 22, kinematic link 23, group of motors 30, rain detector 31, manual operation well 40, manual operation system 41, water proof ring 42.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, one of the present utility model adjustable for height ascending/decending surface wind outlet structure, comprise the air port, ground that air exhaust passage is formed on ground, it also comprises: lifting air port 10, is made up of waterproofing materials, in hollow columnar, is arranged in air port, ground; Lifting gear, to be installed in air exhaust passage and to be formed with ascending/decending air port 10 and be in transmission connection; Rain detector 31, controls lifting gear action; Protector 11, is fixedly installed in the upper port in ascending/decending air port 10.
Namely in air port, ground, lifting air port 10 is installed, automatic rising, the decline of lifting air port 10 is controlled by lifting gear, overcome the dependence of air port to permanent water-resistant barricade, on air port, ground, permanent waterproof barricade need not be set, reduce the requirement to air port surrounding environment, save floor space, decrease the impact of air port on civic landscape, improve disguise and the interruption-free in air port.Control lifting air port automatic lifting running status and adjustable height according to weather conditions Real-Time Monitoring with automatic by rain detector, effectively improve stability and the reliability of air port lifting, avoid rainwater to pour in down a chimney ventilation hole; The upper port of lifting air port 10 is provided with protector, can effectively prevent foreign matter, rainwater enters in air exhaust passage.
Lifting air port 10 is made up of the waterproofing materials possessing rigidity, usually can adopt aluminium alloy plate material.
With reference to Fig. 1, for simplifying lifting gear and making its structure more compact, described lifting gear is made up of a set of active leading screw and nut mechanism and at least a set of passive leading screw and nut mechanism, initiatively leading screw and nut mechanism is driven by group of motors 30, formed between passive leading screw and nut mechanism or between passive leading screw and nut mechanism and active leading screw and nut mechanism by link gear and be in transmission connection, the action of group of motors 30 is controlled by rain detector 31.
With reference to Fig. 1, as the typical form of structure of one, the cross section of described air exhaust passage, lifting air port 10 is rectangular, and the corner in air exhaust passage arranges the guide rail 20 vertically extended by air port, ground respectively downwards.Described lifting gear comprises a set of active leading screw and nut mechanism and the passive leading screw and nut mechanism of two covers that form by screw mandrel 21 and the nut 22 that is meshed with it, and screw mandrel 21 is fixedly mounted in guide rail 20, and 22, nut is fixedly connected with the bottom of lifting air port 10.Described link gear comprises kinematic link 23, and is installed on kinematic link 23 two ends and the conical tooth wheels be meshed being installed on screw mandrel 21 lower end.
During the rainy day, rain detector 31 detects signal, pass to group of motors 30, electric machine rotation, the screw mandrel 21 in direct-drive active leading screw and nut mechanism, and the screw mandrel 21 in passive leading screw and nut mechanism is driven through kinematic link 23, nut 22 drives lifting air port 10 steadily to rise along guide rail 20, until lifting air port 10 body large part is more than air port, ground, is born the function of waterproof barricade by lifting air port 10, stop ground rainwater to enter in air exhaust passage, play and prevent flooding object.During fine day, rain detector 31 detects signal, passes to group of motors 30, motor reversal, and air port 10 steadily drops to below air port, ground along guide rail 20.
With reference to Fig. 1, for avoiding also controlling lifting air port 10 position in the situations such as power failure, the inherent initiatively leading screw and nut mechanism side of described air exhaust passage is also provided with the manual operation well 40 vertically extended by air port, ground downwards, is provided with the manual operation system 41 be in transmission connection with active leading screw and nut mechanism in manual operation well 40.The gear train of the screw mandrel 21 that manual operation system 41 can be connected in active leading screw and nut mechanism by transmission shaft driven is usually formed.
With reference to Fig. 1, described protector 11 can adopt rainproof grid, or adopts by the power-operated shutter of rain detector 31 control action.For avoiding rainwater to flow in air exhaust passage from the gap between air port, ground and lifting air port 10, air port, described ground is installed with the water proof ring 42 acting on lifting air port 10 lateral wall.
Some principles of a kind of adjustable for height ascending/decending surface wind outlet structure of the above the utility model that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
