SU10646A1 - Device for transmitting the distance between the readings of the water level in the water tank - Google Patents

Description

The present invention relates to devices for transmitting the readings of the water level in a water pressure tank, in which the device indicates the water level; It is controlled by pulses of the inductor current coupled to the axis, rotating when the float tank floating in the water is raised or lowered. According to the invention, in order to obtain clear current pulses on an axis, driven by a float with a counterweight, a fist is pushed into a video holder, driving a bar with a weight, which sits on the inductor axis. With a marked rod, the inductor bark, rotating slowly during the first half of a turn, does not produce a current, and when it drops rapidly in the second half of a turn, it sends a current pulse to the instrument, indicating the water level in the tank.

In the schematic drawing of FIG. 1 shows the pulse-sending part of the device proposed; FIG. 2-part of it; FIG. 3-noted device for indicating water level; FIG. 4-polarized electromagnet of this device; FIG. 5 is a circuit for incorporating the latter into the circuit and the inductor.

The proposed device consists of a float 15 (Fig. 1) connected by a Gall chain and a gear wheel 3 with an axis 2,

carrier fist 4 in the form of a half disk with lead plates 17, then an inductor 7, on the axis of which a rod 5 is fixed with a load 6 at its end, rotates together with the inductor shaft using a half disk 4, and finally, an instrument indicating the level of water supplied with polarized an electromagnet 8, 9, 10 with bark 11, 11 connected through gears 12 and 13 with the gear wheel 14, sitting on the axis of the arrow moving against the graduated dial; Inductor 7 and shaft 2 of wheel 3 are mounted on bracket 1, attached to the wall 18 of the water. The diameter of the wheel 3 must be chosen so that one of its turn corresponds to the movement of the ball in the tank per unit length.

The operation of the device is as follows:

The float 15, when it moves up or down (depending on raising or lowering the level in the tank), causes the inductor 7 to rotate by means of a chain of Gall, a gear wheel 3 and a cam 4 acting on the rod 5, which due to its slow movement at the first half turn, not, but at the second, being believed quickly, due to the fall under the action of force

The tin rod 5, sends an electrical impulse to the device, indicating the level of liquid in the tank. Therefore, in the latter, the arrow must move in jerks, moving from one indication to another, differing by one from the first.

The current pulse, which enters the polarized electromagnet 8, 9, 10 (Fig. 3), causes (depending on the current direction) one or the other of the cores 11, which release one of the wheels 12 or 13, which comes into rotation under the action of the weight of the weight 16 and turns on one tooth in the appropriate direction gear wheel 14 with an arrow.

The subject of the patent.

1. A device for transmitting to a distance the water level readings in a water tank, in which the device indicating the water level is controlled by pulses of an inductor coupled to an axis, rotating - when a water tank floating in water rises or lowers, characterized by for coupling osn-2 driven in rotation by moving the float 15, with the axis of the inductor 7, a fist 4 is mounted on the axis 2 in the form of a half-disk, and the rod 5 is fixed on the axis of the inductor 7 with a weight b at its end with the aim of lifting the rod 5 measles inductor 7, rotating slowly during the first half of the rotation of axis 2, did not give a noticeable current, and with a rapid fall of the rod at the beginning of the second half of the rotation of axis 2, the measles of the inductor 7 during fast rotation gave a current pulse in the circuit enclosing the device indicating the water level in tank

 2. In the device described in paragraph 1, the use of a device indicating the water level in the tank and consisting of a polarized electromagnet 8, 9, 10, cor 11, 11 of which act, depending on the direction of current into the winding 10 of the electromagnet, to one of wheels 12 or 13, allowing it to rotate under the influence of the weight of the weight and v13 {1v rotation on one tooth in the corresponding side of the gear 14, which sits on the axis of the arrow, moving against the graduated dial.
