Problems solved by technology

[0003] At present, household heliostats sold in China are basically simplified versions of industrial heliostats, which are inconvenient to install and use.
Wikoda Corporation of the United States launched Solenica's CAIA, which is a heliostat product suitable for home environments. The light direction sensor of this product is an indispensable part of the heliostat. The sensor is fixed and installed on the heliostat through an arc bracket. In the front, because the distance between the sensor and the reflector is relatively close, it will block part of the incident light and reflected light, and the efficiency is low. In addition, this design method of CAIA is not conducive to reducing the cost of household heliostats

Embodiment 1

[0055] This embodiment provides a household heliostat, such as Figure 1-2 As shown, it includes: a reflector 1; in this embodiment, the reflector 1 can be an optical reflector.

[0056] The supporting mechanism includes a bracket 4 and a base 8 , the bracket 4 is arranged on the upper part of the base 8 , and the reflector 1 is rotatably arranged on the bracket 4 .

[0057] The first driving mechanism comprises: a first driving device and a pitch rotary encoder 2; the first driving device includes: a reduction motor 3 and a first torque limiter; the reduction motor 3 communicates with the first torque limiter through the first torque limiter The mirror 1 is connected to drive the mirror 1 to rotate in the pitch direction; the pitch rotary encoder 2 is connected to the pitch rotation axis of the mirror 1 for feeding back the pitch angle of the mirror 1 in the pitch direction In this embodiment, preferably but not limited to this method, the geared motor is preferably a geared...

Embodiment 2

[0065] This embodiment provides a method for determining the sun, which is applied to the household heliostat described in Embodiment 1, including:

[0066] Obtain the angle from the reflector to the target position;

[0067] Calculate the pitch angle and azimuth angle of the sun position at the current moment according to the current time, time zone, and latitude and longitude;

[0068] According to the angle of the reflector to the target position and the angle of the pitch angle and the azimuth angle of the sun position, the target angle of the normal line of the reflector is determined, and the control mechanism controls the rotation of the reflector so that the The current angle of the reflector is equal to the target angle of the normal of the reflector, so that the sunlight can be reflected to the target position;

[0069] The above mentioned angles include: pitch angle and azimuth angle.

[0070] Before equating the mirror's current angle to the target angle of the m...

Embodiment 3

[0083] This embodiment can be used alone, and can also be used in combination with the above embodiments. This embodiment provides a method for determining the date, including the following steps:

Abstract

The invention provides a household heliostat and a heliostat method. The household heliostat comprises a reflecting mirror, a first driving mechanism, comprising a first driving device and a pitchingrotary encoder; the first driving device comprising a speed reducing motor and a first moment limiter, and the speed reducing motor being connected with the reflecting mirror through the first momentlimiter; a second driving mechanism, comprising a second driving device and an azimuth rotary encoder; the second driving device comprising a motor, a speed reducer and a second moment limiter; the motor being connected with the reflecting mirror through the speed reducer and the second moment limiter; and a control mechanism, connected with the gear motor, the pitching rotary encoder, the motor and the azimuth rotary encoder. According to the invention, through the control mechanism, the first driving mechanism and the second driving mechanism, accurate tracking of light of the sun is realized, and sunlight is accurately reflected to a target position. The household use of the heliostat is fully considered, and the heliostat has the characteristics of simplicity in installation, convenience in use and low cost.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a household heliostat and a heliostat method. Background technique [0002] The north-facing residence has poor indoor lighting all year round. Even if the orientation is south-facing, some indoor corners cannot be exposed to sunlight. With the commercial operation of solar thermal power plants, the application of heliostats in the industrial field is becoming more and more mature, and household heliostats are gradually entering thousands of households. [0003] At present, household heliostats sold in China are basically simplified versions of industrial heliostats, which are inconvenient to install and use. Wikoda Corporation of the United States launched Solenica's CAIA, which is a heliostat product suitable for home environments. The light direction sensor of this product is an indispensable part of the heliostat. The sensor is fixed and installed on the helios...
