Description
Technical field
The invention belongs to the technical field of measuring wind-force size instrument, relate in particular to a kind of anemometry instrument that utilizes the visualize of bulb brightness to evaluate wind-force size.
Background technology
at present, existing increasing country develops wind resource, utilizes wind-force to produce electric energy, and the clean energy resource of environmental protection is provided; On the other hand, natural wind is larger or form wind spout, is also very fearful and serious to the destruction of physical environment and human habitat.Wind-force is ubiquitous, and it is exactly blowing of person sensation wind-force that the mankind experience the most direct method of wind-force.Current, the whole world is quite ripe to the early warning report analytic system technology of natural wind, and its accuracy and precognition wind-force disaster etc. are also comparatively accurate.But this type of wind scale is measured and early warning system is only applicable to use in actual outdoor environment, its volume is comparatively huge, and structure is also comparatively complicated.For for testing, show, the work of the anemometry demonstration of the purposes such as teaching is just not too applicable, these all require the structure of this anemometry device must reach simply, it is less that volume also needs, and needs are light and be convenient for carrying.The defects such as the anemoscope of using in existing school just guessed and the size of wind-force be there is accuracy not high by the pop one's head in velocity magnitude of rotation of runner, and the grasp of anemometry is not strong.
Summary of the invention
For the problem of existing anemoscope Shortcomings, the invention provides a kind of anemometry instrument, this anemometry instrument changes the resistance of graphite resistance by the size of wind-force, thereby cause the variation of electric current in circuit, the brightness of bulb is changed, and indicate the size of wind-force to make experiment effect more directly perceived by the registration of reometer, and more science, lively and interesting, it is also more accurate that the grade of its wind-force is measured.
To achieve these goals, the invention provides a kind of anemometry instrument, comprise insulating support seat and be located at the insulating support bar on insulating support seat, on insulating support bar, be hung with the graphite core bar that presss from both sides connection with two electricians, each electrician's folder connects respectively one end of graphite core bar, and one of them electrician's folder is conduction electrician folder; On described insulating support bar, be also provided with the adjustable metal bar being flexibly connected with graphite core bar, adjustable metal bar is connected with bulb, and bulb is connected with bulb switch, and bulb switch is connected with reometer, reometer is connected with stabilized voltage supply, and stabilized voltage supply connects conduction electrician folder; Described adjustable metal bar, bulb, bulb switch, reometer, stabilized voltage supply, conduction electrician's folder are connected in series formation circuit loop successively by wire.In the time of wind blows adjustable metal bar, the adjustable metal bar segment distance that slides on graphite core body, bulb switch turn-on current, now the resistance size of that section of graphite core body between adjustable metal bar and conduction electrician folder is inversely proportional to the electric current of bulb, judges the grade of this wind-force by demonstrations such as the brightness of bulb and the numerical value of reometer.
Further, on described insulating support bar, be also provided with towards the fan of adjustable metal bar, fan is connected with the regulated power supply that can change fan electrical current, is also provided with fan swicth between fan and regulated power supply.In the time being indoor environment, this anemometry instrument, for effects such as teaching demonstrations, need to be added to the fan that wind-force is provided, fan is aimed at adjustable metal bar and can be blown adjustable metal bar and slide certain distance; The electric current that regulated power supply need to be installed to be provided electric current and change fan is controlled the size of wind-force.The circuit of fan work is complete relatively independent separation with the circuit of bulb work, can not be subject to reciprocal influence.
Further, described adjustable metal bar bottom is connected with and is subject to aerofoil.Be subject to the lifting surface area of aerofoil for Chinese People's Anti-Japanese Military and Political College's wind-force, so that the slip of adjustable metal bar is more accurate and stressed convenience.
Further, described adjustable metal bar is provided with and contacts with graphite core bar and can realize the card article that adjustable metal bar becomes to be flexibly connected with graphite core bar shaped.Slide and change the resistance size of graphite core body energising in the activity that is stuck in graphite core body good contact and realizes adjustable metal bar by card article.
Further, between electrician's folder or insulating support rod and card article, be provided with the back-moving spring that can make card article reset.
Further, described adjustable metal bar is installed on insulating support bar so that rotation axis is hinged.The hinged activity that realizes adjustable metal bar with rotation axis is slided, convenient and simple direct.
Further, on described insulating support bar, be also provided with lamp socket, bulb is installed on lamp socket; Switch and fan are installed on insulating support bar.
While surveying wind-force, closed fan swicth and bulb switch, regulate regulated power supply, thereby change by the electric current of fan, changes the speed of fan rotation, observes the brightness of bulb and the registration of reometer, relatively the size of wind-force.In the time that the registration of the electric current of this experiment is 0.18A, the brightness of bulb is darker, and wind-force is probably 3 grades, and in the time that the registration of electric current is 0.2A, the brightness of bulb brightens, and wind-force also becomes greatly, and wind-force is probably 4 grades.In the time that the registration of electric current is 0.24A, it is very bright that the brightness of bulb becomes, and wind-force is probably 5 grades.When calm, adjustable metal bar is vertical, and wind is stronger, and the angle of adjustable metal bar deflection is larger.
In sum, anemometry instrument of the present invention changes the resistance of graphite resistance by the size of wind-force, thereby cause the variation of electric current in circuit, brightness by bulb changes, and indicate the size of wind-force to make experiment effect more directly perceived by the registration of reometer, more science, lively and interesting, it is also more accurate that the grade of its wind-force is measured.Be conducive to promote to impart knowledge to students, improve results of learning, classmates are by watching the experiment of demonstration anemometry instrument, not only vivid but also intuitively concrete, excited classmates' learning interest, vigorous.
