However, if it is made in the shape of a pipe with a circular column, it can be received from the front even if the angle of incidence of the sun's rays is distorted.

A reflection unit 123 may be further included so that sunlight may be evenly irradiated throughout.

At this time, the reflective unit 123 may be simply formed in a flat plate shape, but is not limited thereto, and a concave curved surface may be repeatedly formed on a surface facing each of the heat collecting units 121 to reflect the sun. It is preferable to maximize the heat collecting function of the heat collecting unit 100 by intensively irradiating light rays to each of the plurality of heat collecting units 121 .

It may further include an alarm unit 240 that generates an alarm through an alarm sound, and the alarm unit 240 can be interlocked with the user's mobile device so that the user located inside the building can directly contact the alarm unit 240. Even if it is not possible to check the problem, it is possible to quickly respond to the initial problem by identifying the occurrence of the problem in real time.

At this time, the control unit 500 receives the information sensed by the environment sensor 200 and generates a drive signal for rotating the rotation support unit 300 in the horizontal and/or vertical directions, as described above. The driving of the rotation support 300 may be differently controlled according to information transmitted from the sensor 220, the raindrop sensor 210, and the air flow meter 230.

For example, the control unit 500 controls the heat collecting unit 100 in response to the irradiation direction of the sun's rays detected by the tracking sensor 220 (which can be interpreted as including both the angle of incidence and the movement of the sun). In addition to receiving the sun's rays from the front, the rotation support part 300 is installed so that the insolation time of the sun's rays irradiated to the heat collecting part 100 can be increased according to the direction of the sun moving from sunrise to sunset. By rotating in the horizontal and vertical directions, the heat collecting function of the solar heat using the sunlight in the heat collecting unit 100 can be maximized.

In addition, the control unit 500 detects that snow or rain is falling by the raindrop sensor 210, and when the detected amount of rain exceeds a preset amount of precipitation, the control unit 500 drives the rotation support unit 300 to move the house By adjusting the vertical angle of the heat unit 100, the surface of the heat collecting unit 100 can be naturally washed by flowing rainwater, and when snow is detected by the raindrop sensor 210, the rotation support unit 300 is driven to adjust the vertical angle so that the heat collecting part 100 is completely vertical with respect to the ground, snow is accumulated on the top of the heat collecting part 100, and the heat collecting part 100 and It is possible to prevent damage to the rotation support part 300 from occurring.

In addition, the control unit 500 may preferentially select one of the heat collection function and the protection function according to the strength of the wind sensed by the air flow meter 230 so that the rotation support unit 300 can be driven.

For example, when the intensity of the wind sensed by the air flow meter 230 is less than a predetermined value, it is determined that there is little risk of damage or failure due to wind pressure, and according to the irradiation direction of the sun's rays detected by the tracking sensor 220 By allowing the heat collection unit 100 to rotate, it is possible to preferentially perform the function of collecting solar heat, and in the case of strong winds or typhoons in which the wind intensity detected by the air flow meter 230 exceeds a predetermined value. In this case, it is determined that there is a high risk of damage or failure due to wind pressure, and the heat collecting part 100 is rotated in a horizontal or vertical direction so that the front of the heat collecting part 100 does not face the wind. It is possible to ensure that the protection function of is performed first.

In this way, the rotation support unit 300 rotates in horizontal and vertical directions by the control unit 500 receiving information detected by the environment sensor 200 so that the heat collecting unit 100 can be rotated.

Here, the vertical and horizontal directions mean the vertical and horizontal directions based on the ground on which the support module 330 is installed, and it can be understood that reciprocating rotation in both directions is possible, not in one direction. The rotation of the heat collecting unit 100 by the rotation of the rotation support unit 300 can be more easily understood with reference to the above description.
