Abstract

A device for measuring the temperature of the surface layer of water allows continuous measurement of the surface temperature of the sea in a wide range of surface wave intensities. A resistance thermocouple in the form of a thread is attached to the bottom of the non-wettable halyard. The halyard connects the main buoy with the auxiliary float. The main buoy is equipped with a diverting wing fixed to a bracket. The bracket is associated with a vertical axis passing through the center of the bu. A truncated hollow cone trimmed with fabric is attached to the auxiliary float on a schert with a load. 1 ill.

Description

The invention relates to oceanographic technology and is intended for continuous measurement of the surface temperature of a pest. The device can be used with drifting oceanographic vessels or autonomously. In addition, it can be used to study the surface temperature of any freshwater bodies.

The aim of the invention is to improve the accuracy of surface waves of the layer,

In FIG. 1 and 2 show the proposed device.

The main buoy 1 has a cylindrical shape and is made of polystyrene foam, a vertical axis 2 passes through its center, which is connected by bearings to the bracket 3. In the lower part, the outlet wing 4 is attached to the bracket. In this case, the buoy 1 can freely rotate relative to the wing 4. The wing 4 represents

a metal plate curved along a cylindrical surface. A cable 5 is attached to the bracket 3, connecting the main buoy with the vessel in drift and conducting measurements. A junction box 6 (or measuring unit) is installed on buoy 1, which is connected by cable 7 to a measuring and recording complex on board the vessel. The auxiliary float 8 is connected to the buoy 1 by a floating non-wettable halyard 9, which is held on the surface, tracking its deformation (agitation). A thermocouple of resistance 11 in the form of a thread is connected to the halyard 9 with ties 10 connected to the junction box 6. A thermocouple can also be used as a thermocouple. A pin 12 is attached to the bottom of the auxiliary float 8 with a length of 1 m and a load 13 at the end. In the middle part of the pads 12, floating measles is attached in the form of a truncated hollow circular cone wrapped in fabric, and the core is attached

supports the larger base of the cone in one way or another.

The buoyancy of the main bu 1 is selected so that under a weight load (bracket 3. wing 4, junction box 6) it rises above the water surface no more than 5-10 cm. Auxiliary float 8 is also made of foam, and with a weight load of 13 and core 14 it should rise 1-2cm above the surface.

The device operates as follows (figure 2): the vessel 15 drifts under the influence of wind. A device is lowered from the bow; under the action of the flow, a deflecting buoy 4 generates a force 1, which brings the main buoy 1 out of the perturbed hull of the vessel area 16. As a result of the impact of the flow on the floating core 14, the auxiliary buoy 8 is removed from the main After this, a file 9 with a temperature transducer 11. The length of a temperature transducer 11 and a file 9 is chosen before the start of the experiment, based on the required scale of averaging the surface temperature of the sea.

The buoy 1 is attached by a cable 5 to the bow of the vessel or of any structure such as an arrow and follows the drift vessel outside the track (disturbed by the hull of the vessel area).

The signals from the thermal converter 11, as well as other sensors that can be installed on the OQHOBHOM buoy 1, are transmitted via cable 7 to the measuring and recording complex 17 installed on the vessel.

Due to the fact that the halyard 9 monitors surface deformation, surface waves do not affect the operation of the device.
