Description

FIELD OF THE INVENTION The present invention relates to a propeller hydrometer locomotive in which the rotation of the rotating magnets and the reed seal are controlled.

Until now, I know the time lag of the hydrometric propeller speed by interrupting the fire contact, interrupting the flow of the avon through the photoalectric element, driving the pulses in the electromagnetic circuit, and switching the reed seal with a permanent magnet rod in a magnetic magnet in the arrangement.

This apdaob is not used in a marine propeller type hydromotrlokoj propeller that has a permanent magnet rod exoentrices located at the end of the ooi teleaa propeller, with its magnetlocal oa yo parallel and oaou teleaa propeller. The reed seal I is located behind the end of the ooi teleaa propeller and its 00 is perpendicular to the ooi of the propeller body and the magneto shaft and the parmanent rod magnet used. In the construction of a particular type of propeller aa uses a miniature reed seal which can switch on already the low intensity of the magnetic field and the exoentricated rod magnet, whose dimensions may not be increased relative to the effort to minimize the diameter of the toloo and the non-spherical micrometer. while wrapping the propeller in the morea environment.

The aforementioned nodotaths are removed by the use of two toroidal porcelain magnets placed on a propeller according to the invention, the essence of which is the use of such toroidal magnesia, that the magnetlocates laterally in the longitudinal section of the magnet. The alpha angle and these magnets are located adjacent to the propeller shaft and that the magnet locates and crosses the magnets. This leads to the deformation of the magnetic field * and around the magnotes and to the side of the surface of the magnets that cross and oi, and the intensity of the magnetic field weaves so much that it is not enough

20G 020 to engage the propeller shaft of the placed reed suction. With such ueporiadaai rotate the aa axis of the propeller together with Magnet! spina reed seal only once per revolution.

Connection of two toroidal magnets with rotated magnetloc axis so that the same axis crosses and by placing Jasýčková or a seal parallel to the axis of rotation of the propeller axis and thus the magnets to switch the reed tongue sealing once per revolution of the propeller and no additional anti-magnet with wheel to the sealing axis away from the propeller axis, the construction is very simple without the laborious adjustment of the anti-magnet.

FIG. 1 shows a cross-sectional view of a toroidal magnet along a longitudinal plane and rotating its magnet of its local axis by an angle. FIG. 2 shows the connection of two magnets of this type with the [alpha] 1 [alpha] rotation according to the invention.

FIG. 2, two permanently toroidal magnets 2 and 2 are positioned, which magnetic coil 4 and g are slipping together.

The permanent toroidal magnets 2, 3 used are magnetized in the longitudinal plane of the toroid cross-section such that the magnetlocation axis 4 is deflected from the longitudinal axis by an angle λ. The minimum value of the angle is determined by the diameter of the magnet of the toroid cross section 4.5, and the maximum value of the value of the angle is less than the right angle.

By circumscribing the pairs of permanent toroidal magnlets 2, 3 on a common axis identical to the rotary axis 1 of the hydrometri-ice propeller and rotating the IOH magneto-eyes 4, 5 so that they intersect on the surface of the permanent toroidal magnlets 2, 3. such that on the secret side of the surface where the α and the magnetic axes 4, 6 slip, the intensity of the magnetlocal pole decreases to such an extent that it is not sufficient to close the reed magnetic seal 6 located as described while the opposite side of the surface has pexmanent toroidal magnets 2; where the magnet locates axes 4, 6, the pole intensity sufficient to switch on the reed magnetlocal seal 6. Thus, in the rotor of an ox 1 of a hydxometlok propeller, the reed magnetic seal 6 is only switched once per revolution of the axis 1-prop and thus allows to read speed.

With this arrangement and the use of the permanent toroidal magnets 2, 3 according to the invention, the reed switching of the reed magnetlock seal 6 ropes once per revolution of the hydrometriockey propeller makes it possible to calculate its revolutions and eliminates the need for additional magnet. , which is placed behind the seal so that the magnetic half of one pole of the torch magnet is reduced.

The above-mentioned principle is possible to use * in all devices, in which it is necessary to sense * revs so that the output signal is one pulse per one revolution oal.

to engage the tele-axis axis of the propeller plug. In such an arrangement, the rotating body and the propeller body are only once per revolution. The connection of the toroidal magnets and the rotating magnetic axis so that and to cross and the reed plugs are parallel to the axis of rotation of the oa and drills and thereby the imagnets and turns the reed plug only once for one revolution of the propeller and cannot be used by an additional magnet and oaa perpendicular to the oai anchor amerom oai propeller, designing is very simple without laborious adjustment of the magnet. 1 shows a resistor-like magnet according to the longitudinal plane and the rotation of its magnet by the angle X, FIG. 2 appending yard of these magnets and turning oai according to the invention. 2 and 2 are permanently toroidal magnesia 2 and 2 ' and the magnetic oa 4 and a ' are crossing, the reed maguetical plug 6, which is parallel to the 2 ' 1 free-to-use only once per turn. The permanently toroidal magnets 2, 3 used are magnetized in the longitudinal plane of the to-roid section so that the magnetos 4 and 4 are diverted from the longitudinal angle x. The minimum value of the angle is determined by the magnet positioning of the locus 4, 5 by the toroid and the maximum value of the angle Λ being smaller than the right angle. A permanent toroidal magnet 2, 3 is placed on the common yoke and the rotating axle of the hydrometric propeller is rotated and the magneto-rocker 4, 5 is rotated so that the aatieto crosses the permanent magnet toroidal magnets 2, 3 ' that on that side of the surface where aa magnetic and 4, 4 crosses, and the intensity of the magnetic pole is so diminished that it is not enough to engage the reed magnetic plug6, according to popia, he has pexmanent toroidal magnets 2, 2 · e and magna oai on the opposite side of the post 4, the field strength is sufficient to engage the reed magnetloid 6.
