The upper half circumference of the heat collecting pipe is a light-gathering concave surface 5.1.

The Fresnel condenser lens is in a strip shape, and the heat collecting tube is equal to the Fresnel condenser lens in length.

The water injection pipe and the hot water outlet pipe are hoses.

The technical principle is as follows:

the Fresnel lens is fully distributed with textures, the textures have a light condensation effect, when the area is large, the focal point is long, the focal point is formed by sunlight focusing, light heat energy is collected on one point by the focal point to form a light spot, the light spot is in heat conduction with the light condensation concave surface of the heat collecting pipe, heat is conducted into water in the heat collecting pipe to heat the water, the water is heated, and the water in the heat preservation water storage tank is circularly heated through the water pump and the pipeline for hot water supply application.

The tracking light hole has the following functions: when the sun rises from the east to the west and falls, the light path is an arc line, the arc light hole cover is consistent with the light path in arc shape, the light holes are distributed on the light hole cover, when the sunlight passes through the first light hole, the sunlight irradiates on the corresponding photodiode, the photodiode generates electric energy, the electric energy is amplified and transmitted to the driving coil of the stepping motor to generate a magnetic field, the magnetic field attracts the magnetic pole arranged on the rotor of the stepping motor to enable the stepping motor to rotate for a certain angle, and the stepping motor is arranged on the light collecting cover bracket to drive the light collecting cover to rotate for a certain angle together with the Fresnel light collecting lens to always face the sunlight, so that the Fresnel light collecting lens can track the sunlight to rotate, and the heat collecting efficiency is improved.

When sunlight irradiates the second light hole, the second photodiode emits current, another coil of the stepping motor is connected in an amplifying mode, the coil generates a magnetic field, and the magnetic poles on the rotor rotate to positions corresponding to the coil under the action of the magnetic field to form rotor angle stepping.

When the sun rises from the east again in the night, the stepping motor is still excited from one end to the other end when light irradiates on the first photodiode, and the rotor continues to rotate in a stepping mode.

The innovation points are as follows: a long-strip Fresnel condenser lens is adopted as a focusing heat energy capturing device; a heat collecting pipe with a light-gathering concave surface is used as a heat collecting pipe; the light-gathering cover is controlled to face the sunlight all the time by the light tracking device and the stepping motor, and the heat collection efficiency is improved.

The method is characterized in that:

under natural conditions, sunlight rotates along with the earth, and irradiates the ground at different angles, in particular, the sunlight irradiates on the same day in common, namely, the sunlight irradiates a certain ground object point at different angles, and the illumination intensity of the ground object point receiving the sunlight is different along with the movement of the sunlight; if sunlight is focused, light rays per unit area are focused on one point, and heat can be concentrated due to the heat of the sunlight; the Fresnel lens is a plane with refraction textures, is light and thin, and can be large in area, so that the focusing effect of the Fresnel lens is very good and can be practically applied, while a common convex lens cannot be large and cannot be practically applied; the strip-shaped conical cylindrical Fresnel condenser lens is used for focusing sunlight, the sunlight utilization area can be large, the sunlight is collected at high power, the heat energy of the sunlight can be collected in a large area by adopting the strip-shaped heat collecting tube side, the heat energy is exchanged with water, the high output power is achieved, the water heating capacity is strong, and therefore a large amount of hot water can be obtained for users to use.

Sunlight can rotate on the unthreaded hole device by an angle, and the sunlight tracking device can be applied to sunlight irradiation, so that the sunlight tracking function can be realized.

That is to say, the Fresnel condenser is used for focusing sunlight to generate heat to heat water, so that the solar water heater not only can be applied practically, but also has high heat utilization rate.
