In figure: 1, fan blade 2, favourable turn rotating shaft 3, gravitation iron plate 4, magnet 5, by air blade 6, drive link 7, indicator rotating shaft 8, indicator bearing 9, pointer 10, indicator panel 11, torque spring 12, favourable turn shell.
Embodiment
Below in conjunction with accompanying drawing to embodiment further instruction of the present utility model.
Embodiment 1
As shown in Figure 1: a kind of indicator detecting favourable turn direction and favourable turn speed, comprise fan blade 1, favourable turn rotating shaft 2, by air blade 5, pointer 9, indicator panel 10 and favourable turn shell 12, favourable turn rotating shaft 2 is provided with in described favourable turn shell 12, described favourable turn rotating shaft 2 is provided with fan blade 1, the edge of fan blade 1 is also provided with gravitation iron plate 3, described fan blade 1 correspondence position is provided with by air blade 5, be connected with drive link 6 by air blade 5, described is also provided with magnet 4 by air blade 5 edge placement, described favourable turn shell 12 arranged outside has indicator bearing 8, described indicator rotating shaft 7 is arranged in indicator bearing 8, torque spring 11 is provided with between indicator rotating shaft 7 and indicator bearing 8, described indicator rotating shaft 7 is connected with the drive link 6 through shell of making a connection, described with the indicator rotating shaft 7 of drive link 6 opposite position on be also provided with pointer 9, described indicator panel 10 is fixedly connected with favourable turn shell 12, pointer 9 is positioned at indicator panel 10 just.
The utility model is in use: provided with fan blade in favourable turn rotating shaft, gravitation iron plate fan blade edge is equipped with, be provided with by air blade with fan blade correspondence position, magnet is equipped with on edge to wind-engaging blade edge, be connected by air blade with drive link and pass through indicator rotating shaft and be connected with pointer, drive link can rotate around indicator rotating shaft, indicator rotating shaft is arranged in indicator rotating shaft, torque spring is equipped with in indicator rotating shaft, outside pointer, indicator panel is housed, indicator rotating shaft and indicator panel are installed on favourable turn shell.
When fan blade rotates under bearing of making a connection drives, the swirling eddy produced is rotated by the attractive force between gravitation iron plate and magnet and fan blade, jointly to the effect producing power by air blade, the resistance overcoming torque spring by drive link by air blade drives indicators turn, by observing the running status determined to make a connection in the position of pointer in indicator panel, comprising the height of rotating speed and turning to.
When favourable turn is stopped transport or fan blade comes off, pointer indicates in centre position under the effect of torque spring.
When normally running when making a connection, due to favourable turn axle High Rotation Speed, drive fan blade to rotate, make around fan blade, to produce strong swirling eddy, blow and produce larger moment of torsion by air blade, the reactive torque driving drive link to overcome torque spring by air blade makes needle deflection to maximum position.
When favourable turn rotating speed is lower, the swirling eddy that fan blade produces is more weak, and pointer, under the acting in conjunction of wind-force and torque spring, deflects to the centre position between pointer zero point and maximum position.
When there is reversing due to other reason when making a connection after stoppage in transit, because rotating speed is very low, the swirling eddy that fan blade produces is ignored, and the acting force between gravitation iron plate and magnet accounts for leading factor, under the intermittent action of magnetic pull, pointer is swung at zero crossings.
When favourable turn reverse direction operation, pointer will deflect to opposite side.
