Description

The invention consists of two parts: I) a receiving device or a sinker with two contacts and with a soluble electrolyte or with a float that is lowered into a borehole and rolled into a circuit signals the moment the device is immersed in water, and 2) the drum, winding t and wire , connected to the receiver weights, have 1, its devices, which provide winding of both traction and especially wires with regular consecutive cuffs, which allows determining with sufficient accuracy the height of the water level by the number of revolutions of the drum.

In FIG. 1 shows a vertical section of a sinker; FIG. l-option-contact device with a float; FIG. 2, 3 and 4-view of the drum and casing, respectively, from the side, front and top; FIG. 5- detail of one end of the axis of the drum; FIG. 6 - part of the carriage and the screwed part in it.

On the ground (Fig. 1), there is a larger sinker g through which the paired wire passes and ends at the bottom with two contacts s, between which there is an electrolyte soluble in water t. Instead of the latter, a float t can be applied, attached to the warp walls of the cylinder EI Ji with threads and a chain when the sinker sinks

into the water (Fig. 1) - T and p and the wire and the double cylindrical drum a b fixed to the axis OOi are wound on a fixed pipe (Figs. 2, 3 and 4). The winding goes evenly with laying the wire and the wire exactly in turn, and therefore the length of the unwound rod can be determined by the number of revolutions of the drum.

For precision winding, pull on a part of the drum and the device is strengthened by means of clamps / on the casing of the borehole and in such a way that the end of the pull, j, pulled by the weight g, passes through guide pins along the axis of the borehole. When the drum is rotated using the knob e for unwinding the crud, the entire drum with its axis OOi moves with each full rotation in the axial direction by a distance equal to the diameter of the thrust prop. Thus, the drum-hanging part of the thrust rod and the guide device n invariably appear on the extension of the borehole axis. Such a movement of the drum occurs due to cutting at the end of its axis, which, in its cylindrical part, lies in the sleeve / 1 (Fig. 4 and 5), and through the sleeve / 2 goes but cutting, whose pitch is equal to the diameter of the thread.

For accuracy of the wire and to another part of the drum b, the following device serves.

On the fixed clamp Oz (Figs. 2 and 3), on which the guiding device W is fastened, a roller τ is mounted on the axis 0s, which serves as a guide for the wire and; on the clamp Oz, as on an axis, the carriage b is fitted, equipped with a roller Tc on axis 0 and held from the angular displacement of the guide I sliding along the clamp Oz. Between the branches of the carriage b, mounted on the axis 02, there is a part i, freely rotating on this axis, cylindrical with an annular undercut, (Figs. 3, 4 and 6); the full width of each ring is equal to the diameter of the wire. The separating both parts of the drum (and 6 the annular protrusion d is provided on its cylindrical surface with a screw thread, the pitch of which is also equal to the wire diameter; the thread is applied in such a way that at each complete revolution of the drum a, the carriage b is displaced in the direction of the drum axis by the length of the diameter of the wire, at which the wire hanging from the drum part b gets the further desired direction by the rockers b and t,

At the top, parts of the device are wires and are connected to an electric battery and signal

device (electroscope, electric bell, etc.). Even with a small immersion of the contacts S or a float t in the water, the current closes and a signal is given.

The subject of the pathet.

1.A device for measuring the level of water in boreholes by closing an electric current circuit using a sinker, characterized in that the cylinder lowered into SREV has two insulated wires that go to the bottom of the cylinder and serves as a cavity in the lower part to place a soluble electrolyte that, when it reaches the cylinder, makes fresh water a conductor of electricity (Fig. 1), in order to close the current.

2. In the apparatus specified in paragraph 1, a device for lowering the instrument into a well, characterized by the use of a two-piece a and 6 drum equipped with a screw axis OOi for moving it along the axis when turning, and located on the drum between the parts a and & cutting d serving to move the carriage 1g, pushes the rollers and; and w, which serve to guide the pair of electrical wires. f ng 2 Fkg.4
