Description

Family expenses weather forecast center weathervane

Technical field

The utility model relates to a kind ofly measures wind direction or/and the weathervane of wind speed.

Background technology

Patent document number is that the utility model patent of CN2599588Y discloses a kind of " contactless sand prevention weathervane sensor ".This sensor is made up of double leaf weathervane chassis, jewel bearing, magnet steel, pivot, wind direction box, Hall circuit switch, several resistive elements, sleeve and socket.Its advantage is to rotate sensitivity, can prevent that the grains of sand intrusion from running out bearing, and reduced the lead use amount of Hall circuit switch.But this sensor exists following shortcoming and defect: 1, volume ratio is huger, is not suitable for adopting in the heart in the weather forecast of family; 2, because jewel bearing still is exposed among the air, is subjected to the invasion and attack of the grains of sand unavoidably and weares and teares; 3, the complex structure of Hall circuit switch increases cost.

Summary of the invention

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, provides a kind of volume small and exquisite, and the grains of sand are difficult to invade bearing and contactor family expenses weather forecast center weathervane simple in structure.

Another purpose of the present utility model is except achieving the above object, the family expenses weather forecast center weathervane of all right measuring wind.

The designer proposes following technical scheme promptly can realize above-mentioned first purpose: the weathervane of the technical program is the same with prior art, comprises weathervane rotary part, wind direction box, circuit board and coupling sleeve, and its improvement is:

The middle part of said weathervane rotary part is provided with a cap, and the center of this cap is provided with a hole with the housing washer transition fit, is the aperture that the side of B is provided with an assembling magnetic post apart from the length in this hole, and a magnetic post is housed in this aperture;

The center of the case top of said wind direction box is provided with a minor axis that raises up, and the core hole of a rolling bearing and this minor axis wringing fit are assembled together, and the outer ring of this bearing is contained in the hole at above-mentioned cap center; Also be provided with a seam circle that matches with the cap lower end in the periphery of this minor axis;

A circuit board is contained in the top in the above-mentioned wind direction box, 8 tongue tubes parallel with one another at this circuit board upper edge circumference radial equipartition, and each tongue tube is B apart from the distance in the center of circle; It is one group build-out resistor that one end parallel connection of each tongue tube 2, and the resistance after per two build-out resistor parallel connections is all inequality, and the resistance after two groups of adjacent build-out resistor parallel connections is also different; Below this circuit board, also fixing a socket that can be connected with computer;

The top of said coupling sleeve is provided with a cover plate, and this cover plate is assemblied in the wind direction box, and the endoporus of coupling sleeve can connect with the support of weathervane.

After above-mentioned weathervane assembled, the tip of its rotary part was oriented to north.When circuit board and power connection, the weathervane rotary part rotates under air-flow or wind action.If the weathervane rotary part rests on a certain orientation, at this moment the magnetic post of being adorned in the cap certain tongue tube lucky and on the circuit board is relative, then connect this tongue tube, socket outputs to information to detect in the test circuit at family expenses weather forecast center and uses then, and being transferred to computer, computer is through showing the direction of wind on the display screen at family expenses weather forecast center after the software processes; If the magnetic post rests on the centre of certain two tongue tube on the circuit board, then connect this two tongue tubes simultaneously, display screen then can show the particular location of wind direction.Because uniform 8 tongue tubes on the circuit board, these tongue tubes have mated the resistance combination of 16 kinds of different resistances by calculating, therefore can detect the wind directions that resolution is 22.5 degree.

The designer proposes following technical scheme promptly can realize above-mentioned second purpose: this programme is on the basis of such scheme, said weathervane rotary part is designed to one three leaf weathervane rotary part, and it comprises semisphere rotation cap and three semisphere vanes that link up by pull bar respectively that are uniformly distributed along the circumference at middle part; And, in the circuit of circuit board, also be connected to the tongue tube of a measuring wind.Can give the relevant information of test circuit and computer conveying air velocity and on display screen, show the numerical value of wind speed by this switch.

The beneficial effects of the utility model are:

1, this weathervane design compactly, small and exquisite, cost is low, is suitable in the family expenses weather forecast adopting in the heart;

2, owing to be provided with the seam circle that matches with the cap lower end in the periphery of the minor axis at the top of wind direction box, bearing is enclosed in the cavity between cap and the wind direction box, make grit be difficult to invade in the bearing, therefore prolonged the serviceable life of bearing greatly;

3, have only 8 tongue tubes on its circuit board, and the structure of this tongue tube is very simple,, but still can reflects the wind direction in 16 orientation so this circuit board is with low cost;

4, the size of wind speed can also be measured and show to second kind of technical scheme of the present utility model.

In order to make the utility model more clear, it is described further below by drawings and Examples.
