SU59359A1 - Installation for measuring evaporation from a water surface - Google Patents

Description

The practice of using stationary evaporators (systems of Lermontov-LyuboSlavbky, L'vovich, etc.) and rain gauges for work afloat yielded negative results.

In addition to the inconvenience in obscuration of these devices during their afloat work, and the environment of their work require a fundamentally different structural decision for both the instruments themselves and the way they are installed in water.

The subject of this author's certificate is a device for measuring evaporation from a water surface, which, like the well-known, consists of a raft, an evaporator and a rain gauge, but differs from them mainly due to the fact that the evaporator and rain gauge are floating and connected. with the raft by means of a flexible connection (and not mounted on it); this operation prevents the evaporator and rain gauge from shocks. In addition, the apparatus has a number of features listed below in the subject of the invention.

The invention is illustrated in the drawing; in FIG. 1 which shows the proposed installation in the plan, in FIG. 2 shows a section along AB (FIG. 1),

in fig. 3 - a floating evaporator in plan (one half), in FIG. 4 is a side view thereof; in FIG. 5 is a floating rain gauge in the plan; FIG. b - side view, in fig. 7 shows the longitudinal check valve of the rain gauge and in FIG. 8 - water epna tube in longitudinal section.

As stated above, the installation consists of a vaporizer, a rain gauge and a raft, which is a floating structure for these devices. In addition, the floating frame may have a floating raft located around the frame on which meteorological instruments are installed.

The floating railing (not shown in the drawing) is designed as an octagon made of 18-20 diameter logs, fastened together by a scarf iron iron shoes. In one of the vertices of the octagon there is a passage for the boat. The attachment of the buoyant frame 1 to the buoyant enclosure, as well as the buoyant evaporator 2 and the rain gauge 3 to the frame 1 are not designed to be rigid, but elastic, in the form of a system of thrones 4 on the blocks 5 with counterweights 6. This mounting is largely guaranteed by devices 2 and 3 from jolts in

time of agitation and thus from splashing water out of the device and, conversely, from getting water into these latter.

The buoyant fence is secured in place by the Korea system. Anchors are attached to the fence not tightly, but through blocks with counterweights. Thus, the vertical movements of the floating barrier connected with the change in the water level of the reservoir are carried out by moving the counterweights associated with the fodder through the blocks.

The buoyant frame 1 is designed in a square plan, made of wood, with a grating platform 7 for access to the instruments and for the placement of meteorological equipment, for example, an anemometer 8, etc.

The fastening of the frame 1 to the fence is also advisable to perform elastic pas counterweights.

The floating evaporator 2 has a receiving area in the form of a square of 10,000 dM- (100 cm side of the square). The possibility of an arbitrary change in the height of the sides of the evaporator is hell with a mirror of water by appropriately moving the floats 9 supporting the evaporator in the guide bars 10.

Additionally, it is possible to change the draft and the buoyancy of the evaporator by supplying water to the floats, for which they are made hollow. The float is released from water by means of a hand-autofuncture hand pump.

The evaporator is equipped with a system of trap pockets against splashing water out of the evaporator.

At the sides of the evaporator, special water discharge shelves have been released to prevent water from entering the device.

Inside the evaporator, diaphragm 11 is installed diagonally 11 - dampers (of plywood).

For measuring the levels, the evaporator is equipped with a water meter tube, which is located at heats 13 with indicators 14 for making level readings on the scale of the glass tube 12. The scale zero can be set (if desired) at different elevations by appropriately moving the glass tube 12, fastened with a cap nut 15. The evaporator can be easily equipped with a level recorder. The evaporator readings recorded by the float 13 can be detected from the shore using binoculars.

The evaporator and float body is made of sheet iron. The frame is made of angle iron.

The floats are provided with a feed nipple 16 and a water tube 17.

The buoyant rain gauge 3 also has a receiving area of 10,000 cm — in the form of a square with a side of 100 cm.

A rain gauge receiver 20 is received with a capacity of approximately 8 liters. As in the evaporator, the possibility of an arbitrary change in the height of the flanges above the water mirror is provided here by appropriate movement of floats 18 supporting the rain gauge in the guide bars 19. It is possible to control the draft and stability of the rain gauge with the help of a cargo attached to the bottom of the receiver 20.

The extraction of water from the receiver 20 of the rain gauge is carried out pneumatically by means of a hand-held auto-pump. Air from the pump is supplied to the tube 21, the measuring vessel is connected to the tube 22.

A check valve 23 is installed in the receiver in order to close the receiving opening during the extraction of water from the receiver. The valve is a shut-off cone 24, pressed by the spring 25, and a regulating screw 26 and covered with a grid 27 attached to the rain body.

The subject matter of the invention.
