Description

The utility model relates to solar technology and water heating installations and can be used to heat water (snow, ice) in expeditionary conditions, as well as in remote areas and zones of low temperatures.

Known water heating installation (RU 2324121, F24J 2/34, publ. 05/10/2008), including a container, inside of which a solar energy absorber is installed on floats, made in the form of a funnel with a drain pipe directed towards the bottom of the container, a tap connected with a hose to drain tube, the drain tube is made protruding into the funnel, the wall of the funnel forming is hollow, while the wall cavity in its upper part, below the immersion level, communicates with the space located behind the outer wall, and at the drain tube it communicates with the space behind its inner wall.

The disadvantage of the analogue is limited mobility, as well as design features that are inapplicable in the harsh climatic conditions of northern latitudes.

Known solar water heater (RU 141541, F24J 2/20, publ. 07.08.2013), including a rectangular screen, equipped with a system for supplying cold and removing heated water, in which the screen is made of a sheet of translucent material with a honeycomb structure, located with the orientation of the channels in vertical plane, with a funnel hermetically fixed on the upper part, communicating with the inner channels of the screen, inside which a perforated pipe for water supply is placed, and a tray installed under the lower part of the screen for receiving heated water, and the funnel and the tray are connected by an overflow pipeline.

The disadvantage of the analogue is manual regulation of the water flow rate by tilting the screen, which reduces the autonomy of the device.

Known mobile solar water heating installation (RU 72047, F24J 2/42, publ. 03/27/2008), containing a transport unit in the form of a rectangular container, including a front wall, rear wall, bottom and roof, in the inner space of which is rigidly installed for its entire length an inclined partition structurally connecting the upper longitudinal edge of the rear wall with the front wall with an inclination towards the latter, the roof of the container of which and part of the front wall are hinged, solar collectors are installed respectively on the surface of the inclined partition of the container, on the inner surface of the folding part of the front wall and on the inner surface of the hinged roof, the accumulator tank, the pumping group and the rest of the equipment, and pipelines are installed in the inner space of the container under the inclined partition.

The disadvantage of the analogue is the impossibility of controlling the overheating of water and the use of materials of construction subject to energy loss from heat exchange.

The closest to the proposed device is a solar heater (RU 2250420, F24J 2/00, publ. 04/20/2005), which includes a heat-insulating body with a glazed window, a heat-conducting container for liquid located in the body, including one with a black or selective outer surface, supplying and liquid outlet pipes made in the form of a single neck in the upper part of the tank, in the lower part of the tank there is a flat or flat support base of the solar heater with stiffening ribs, a glazed window in a removable or non-removable, hard, or semi-rigid, or soft heat-insulating body is made with an inclination of 30- 120 degrees relative to the plane of the reference base.

The disadvantage of this device is the low efficiency when using one glazed window, as well as the filling / draining system of the used liquid in the form of a single neck, which leads to inconvenience in operation and the possible presence of impurities in the resulting liquid that affect the quality of water.

The task of the utility model is to increase the efficiency of converting solar energy into thermal energy.

The technical result of the utility model is to increase the accumulation of solar energy.

The task and the technical result are achieved by the fact that an autonomous water-heating device, including a heat-insulating body, a heat-conducting container with a black surface, a neck for water supply, a glazed window, according to the utility model contains a glazed window in the upper part of the body, a heat-insulating material along the perimeter of the heat-insulating body with the exception of the area where glazed windows are located, an optical installation based on Fresnel lenses located between the glazed windows and a heat-conducting tank, panels with closable openings on the outer top and front walls of the device, a removable mechanical filter with a sump and a tap for water supply in the lower part of the case.

The essence of the utility model is illustrated by drawings, where Fig. 1 shows a general view of an autonomous water heating device in a working (deployed) position; in fig. 2 schematically shows a cross-section of a self-contained water heater in transport position.

An autonomous mobile water heating device includes a heat-insulating housing 1 with glazed windows on the upper 2 and front 3 walls of the device, inside which there is a heat-conducting container for liquid 4, made of stainless steel 5 with a black surface and thickened walls facing the sides with glazed windows 2 , 3, heat-insulating material, for example, made of ecowool 6, 7 along the perimeter of the heat-insulating body 1, with the exception of the area of location of glazed windows 2, 3, a supply pipe for supplying water (snow, ice) in the form of a neck 8, located in the upper part of the body, optical installation based on Fresnel lenses 9, 10, located between glazed windows 2, 3 and heat-conducting capacity 4 and limited by panels with closable openings 11, 12 on the top and front walls of the device, removable mechanical filter 13 with a sump 14, a tap for water supply 15 at the bottom of the case, cover 16 on the back of the case for access to the removal a mechanical filter 13 with a sump 14 and a tap 15.

An autonomous mobile water heater works as follows. In sunny weather (for the Arctic zone on a polar day), the heat-insulating body 1 is installed on a previously prepared base, which can be either rotating or stationary, and is oriented by glazed windows 2, 3 towards the sun. The heat-conducting container 4, the body of which is made of stainless steel 5 with a black surface, enclosed in a heat-insulating material 6, 7, which makes it possible to compensate for the heat loss from the walls of the structure when interacting with the environment, is filled with water (snow, ice) through the neck 8. Sun rays, passing through an optical installation based on Fresnel lenses 9, 10, the conical surface of which faces the heat-conducting container 4, fall on the walls made of stainless steel 5, and heat the water in the heat-conducting container 4. For uniform heating of the water, the front and top walls are thickened, and the bottom and three side walls of the body of the heat-conducting container 4 are covered with black thermal paint. The intensification of the stratification process (stratification of a liquid by density due to a temperature gradient) can be achieved by additionally introducing an optical setup based on Fresnel lenses not only on the side, but also on the upper wall. To prevent overheating of the water in the heat-conducting container 4, the optical installation based on Fresnel lenses 9, 10, through which the sun's rays enter, is equipped with panels with closable sections 11, 12, which reduce the active area of the received ray fluxes. The heated water passes through a removable mechanical filter 13 with a sump 14 and enters the area of the tap 15, which is accessed through the cover 16 on the back of the heat-insulating body 1.

So, the claimed utility model allows you to improve the design of the solar heater and increase the efficiency of converting solar energy into thermal energy, increase the accumulation of solar energy.
