Description

The utility model relates to solar technology that provides measurement of solar radiation. It can be used in environmental monitoring: in meteorology, climatology and ecology.

A device [1] is known, comprising a housing, two thermocouples made of metal with a shape memory effect, one of which is open to sunlight, and the other is closed by a light screen, while both thermocouples are kinematically connected to each other and to the rotation axis, which is equipped with a writing an element interacting with a recording device fixing the oscillatory movements of the writing element. These movements occur due to the temperature difference between the shielded and unshielded elements, reflecting the change in the level of solar radiation.

The disadvantage of this device is the inability to process and transmit the received data in real time.

The task that this utility model is aimed at is creating a real-time device.

The specified technical result in the implementation of the utility model is achieved by the fact that, as in the known method of measuring solar radiation, the device comprises a housing, two identical thermocouples made of metal with a shape memory effect, one of which is open to sunlight, and the other is closed by a light screen , while both thermocouples are kinematically connected with each other and the axis of rotation.

In contrast to the known device, the device is equipped with a strain gauge [2] mounted on an elastic plate and constituting a single elastic element with one end of which is installed in the housing, and the other is in contact with a leash mounted on the axis of rotation, the rotation of which is ensured by a leash the bending moment of the elastic element, which gives an electrical signal proportional to the angle of bending.

The realization of this goal is based on the work of metal elements with a shape memory effect, connected in a differential circuit relative to each other using the rotation axis. With a different degree of illumination by the sun's rays, the pair elements have a temperature difference, therefore, due to the shape memory effect and the differential circuit of switching on the elements, the axis rotates in one direction or another by an angle proportional to the temperature difference. The rotation of the axis is transmitted to the elastic element, which ensures its bending by an angle proportional to the degree of illumination, i.e. the level of solar radiation. The elastic element generates an electrical signal proportional to the bending angle, which, with the help of electronic equipment, enters the information processing center in real time.

In FIG. The proposed device is presented. It contains heat-sensitive elements 1 and counter springs 2, pairwise separated by a light screen 3, attached to the ends of the lever 4, freely rotating relative to the axis 5, on which the leash 6 is fixed, which is in contact with the elastic element 7 connected to the electronic unit 8.

The device operates as follows. Since two identical elements 1, separated by a light screen 3, are connected by means of levers 4 towards each other with respect to the direction of rotation of axis 5, this axis in the absence of solar radiation (with the same course of temperature change on elements 1) will remain stationary, but with different the course (the presence of radiation) will rotate, turning by an angle proportional to the temperature difference on each element 1, transmitting a bending moment to the elastic element 7 by means of a leash 6. The magnitude of the bend and issued electrically of the signal element 7 will be proportional to the temperature difference between the illuminated and non-illuminated element 1, i.e. the intensity of solar radiation. The electronic unit 8 will receive and transmit signals coming from the element to the data center.

As a result of the operation of the device, information on the current level of solar radiation in real time will be obtained.
