DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] See also Figure 1~Figure 4 ,in Figure 1 is a side view of the first embodiment of the utility model, Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 A partial enlarged view of point B in the middle. Figure 4 The utility model Figure 2 Sectional view along the CC line.

[0027] The utility model provides a photothermal reflector installation structure, including a reflector 101, an anti-dropping piece, a mirror bracket 102, two mounting frames 103 and an adjustment mechanism, the adjustment mechanism including a driven gear 106, a first motor 107, a mounting box 108 and an L-shaped frame 109, the anti-dropping piece including a knob bolt 111, two L-shaped blocks 112 and an anti-dropping plate 113, the above-mentioned scheme solves the technical problem that the angle of the reflector 101 is not easy to adjust, thereby reducing the practicality, because the mirror fixing bracket and the collector main bracket are fixedly connected by bolts.

[0028] According to this specific embodiment, an inverted L-shaped plate 104 is provided at one end of the mirror bracket 102, and a support shaft 105 is provided in the middle of the mirror bracket 102. The reflector 101 is fixedly connected to the mirror bracket 102 through the anti-slip component, and is located on the upper end surface of the mirror bracket 102 and is abutted against the inverted L-shaped plate 104. The anti-slip component is located at the other end of the mirror bracket 102. The mirror bracket 102 is rotatably connected to the corresponding mounting bracket 103 through the support shaft 105, and is located between the two mounting brackets 103. The arrangement of the support shaft 105 and the mounting bracket 103 can facilitate the support of the mirror bracket 102, and the anti-slip component and the inverted L-shaped plate 104 can facilitate the fixing of the reflector 101, thereby preventing the reflector 101 from loosening or falling off.

[0029] The output end of the first motor 107 is provided with a driving gear 110, the driven gear 106 is fixedly connected to the support shaft 105, and is sleeved on one end of the support shaft 105, and is also located in the installation box 108, the first motor 107 is fixedly connected to the L-shaped frame 109, and is located on the L-shaped frame 109, the driving gear 110 is meshed with the driven gear 106, and is located on the outside of the driven gear 106, and is also located in the installation box 108, and the installation box 108 is fixedly connected to the L-shaped frame 109. The support shaft 105 passes through the mounting box 108, and the L-shaped frame 109 is fixedly connected to the corresponding mounting frame 103 and is located at the inner top of the mounting frame 103. The driven gear 106 is driven to rotate by the driving gear 110, so that the driven gear 106 drives the support shaft 105 to rotate, so that the angle of the mirror bracket 102 can be adjusted, thereby driving the reflector 101 to move, thereby improving the practicability of the reflector 101.

[0030] Secondly, the volume of the driven gear 106 is many times that of the driving gear 110. The small driving gear 110 drives the large driven gear 106 to rotate, which can change the speed of the output shaft. Since the number of teeth of the large and small gears is different, their rotation speeds will also be different; the rotation speed of the small gear is usually faster than that of the large gear. Therefore, during the transmission process, the rapid rotation of the small gear can be converted into the slow rotation of the large gear, thereby reducing the speed; thereby improving the accuracy of adjusting the angle of the reflector 101.

[0031] Again, the anti-slip plate 113 is provided with an adjustment slot 114, the knob bolt 111 is threadedly connected to the mirror bracket 102, and is located at the other end of the mirror bracket 102, and passes through the adjustment slot 114, the two L-shaped blocks 112 are fixedly connected to the mirror bracket 102, and are located at the other end of the mirror bracket 102, the anti-slip plate 113 is slidably connected to the corresponding L-shaped blocks 112 respectively, and is located between the two L-shaped blocks 112, and abuts against the mirror bracket 102 and the reflector 101, by rotating the knob bolt 111 clockwise, the knob bolt 111 is threadedly connected to the mirror bracket 102, and the anti-slip plate 113 is tightly abutted against the mirror bracket 102 and the reflector 101, when the reflector 101 needs to be removed, the knob bolt 111 is rotated counterclockwise to move the anti-slip plate 113 away from the reflector 101.

[0032] When the utility model is used to adjust the angle of the reflector 101, the first motor 107 is started to drive the driving gear 110, the driving gear 110 is meshed with the driven gear 106, and the support shaft 105 is rotated under the action of the driven gear 106, so that the mirror bracket 102 drives the reflector 101 to rotate around the support shaft 105, thereby completing the adjustment of its angle, thereby solving the technical problem that the angle of the reflector 101 is not easy to adjust due to the fact that the mirror fixing bracket and the collector main bracket are fixedly connected by bolts, thereby reducing the practicality.

[0033] The second embodiment is:

The stability of the mounting frame 103 can be improved by the reinforcing rods 201, and the arrangement of the fixing rings 202 and the fixing bolts 203 can facilitate the installation of the device.

[0037] The cleaning mechanism is disposed on the supporting shaft 105 and is also supported against the upper end surface of the reflecting mirror 101 .

The second motor 207 drives the rotating shaft 205, so that the rotating shaft 205 drives the multiple telescopic components to move, and the cleaning brush 204 wipes the upper end surface of the reflector 101, thereby cleaning the dust and dirt on the surface of the reflector 101, and the telescopic component has the function of adaptively adjusting the curvature of the upper end surface of the reflector 101.
