RU61702U1 - HYDROMETRIC WINCH - Google Patents

Abstract

The utility model is a lifting device, namely a winch for creating holding forces and moving measuring devices in the production of hydrological measurements using small-sized floating equipment. A disadvantage of existing hydrometric winches is the impossibility of their use on small vessels due to the impossibility of rigid fastening on a deck having a small thickness, which creates its deformation when operating hydrometric winches. A hydrometric winch is proposed, including a view placed on two racks with a cable wound on it and an indicator of its length, a take-out boom with a stop at one end and a guide block through which the cable runs off at the other, characterized in that the take-out boom has a transverse cross at one end placed emphasis and fixed platform for attaching view racks.

Description

The utility model relates to the field of lifting devices, namely to winches, and can be used to create holding forces and move measuring devices during hydrological measurements using small-sized floating equipment.

Hydrometric winches are known, containing a bed with a drum (view) placed on it, on which a cable is wound, an extension boom with a guide block at the end through which the cable runs, a depth counter (Chebotarev A.I. Hydrological Dictionary. L .: Gidrometeoizdat, 1970 p.67, Bykov V.D., Vasiliev A.V., Hydrometry L.: Hydrometeoizdat - 1977).

Known portable hydrometric winch for measurements on rivers (Index C88.1.01 of the Hydrological Operational Multipurpose System of the World Meteorological Organization (http://www.wmo.ch/web/homs/projects/Components/Russian/c88101.html)) from the bridge with hydrometer turntables or bathometers mounted on a frame, on the cable drum of which a suspension cable with a conductive core is attached.

The PI-24M hydrometric winch is also known (PI-24M hydrometric winch. State enterprise Gidrometpribor advertising prospectus 199053, St. Petersburg, VO, 2nd line, d.23), taken as a prototype containing a view with wound on two racks on it with a cable, a pointer to the length of the cable, an extension boom with an emphasis on the deck at one end and a guide block on the other through which the cable runs. The view and the boom are attached to the deck autonomously.

The disadvantage of these analogues and prototype is the impossibility of their use on small vessels due to the impracticability of rigid fastening

on a deck having a small thickness, which creates its deformation during the operation of hydrometric winches.

The purpose of this utility model is to ensure the use of hydrometric winches on small vessels.

The goal is provided by changing the design of the boom.

This technical result is obtained due to the fact that in the well-known hydrometric winch the extension boom is equipped with a platform for connecting to the view posts and a "T" -shaped stop.

The essence of the invention is illustrated in the drawing.

Figure 1 shows the design of the solution.

The proposed hydrometric winch includes (Fig. 1) a view placed on two racks 1 with a cable length indicator 2 with a cable 3 wound on it, a take-out boom 4 with a transverse stop 5 at one end, a guide block 6 through which the cable runs off, at the other and a platform for attaching a view 7 located between them.

The proposed hydrometric winch is used as follows (Figure 1).

The take-off arrow 4 with the transverse T-shaped stop 5 located at one end and the view 2 fixed to it is placed in such a way that the stop is placed at the junction of the deck and the side of the small vessel having an angle of 90 ° or less. With the extension boom 4 fixed in this way, the measuring devices are immersed in water using the view 2.

Claims (2)

1. Hydrometric winch, including a view placed on two racks with a cable wound on it and an indicator of its length, a take-out boom with a stop at one end and a guide block through which the cable runs off at the other, characterized in that the take-out boom has a transverse cross at one end fixed emphasis. 2. The winch according to claim 1, characterized in that for fastening the view on the boom, the latter is equipped with a fixed platform for attaching the racks of the view.
