[0033] The four corner surfaces of the base 1 are provided with mounting holes 3 .

[0034] When using the reflective screen, the reflective screen is installed at a high place of the equipment. In daily production and life, especially in outdoor equipment, the main heat source is generated by the sun. When the equipment is exposed to the sun, especially in hot summer, the reflective screen is installed at a high place of the equipment to reflect the thermal radiation. The drive motor 5 is started to drive the worm 6 to rotate, the worm 6 drives the worm wheel 7 to rotate, the worm wheel 7 drives the first rotating shaft 4 and the connecting column 8 to rotate, the connecting column 8 drives the reflective screen mounting seat 10, the thermal radiation reflective screen 11, the second rotating shaft 12, the clamping block 13, the connecting rod 14, the arc groove 15 and the clamping groove 16 to rotate, and the angle of the thermal radiation reflective screen 11 is adjusted to facilitate the adjustment of the angle between the thermal radiation reflective screen 11 and the sun, so as to facilitate the reflection of the thermal radiation generated by the sun.

[0035] By using the weft 17, the warp 18 and the aluminum foil 19, it is convenient to improve the reflectivity of thermal radiation. Since the weft 17 and the warp 18 are both glass fiber yarns, the glass fiber yarns have a high reflectivity and can reflect most of the radiant heat back to the heat source, thereby improving the reflection efficiency of thermal radiation.

[0036] When the reflector is used for a long time, the surface of the thermal radiation reflector 11 will absorb a certain amount of dust, and it needs to be cleaned regularly. In order to improve the reflective effect of the thermal radiation reflector 11, the thermal radiation reflector 11 is usually installed at a high place of the equipment. Due to the high position of the thermal radiation reflector 11, it is not convenient to disassemble and clean it. At this time, you only need to pull the card blocks 13 to both ends to make the card blocks 13 rotate around the second rotating shaft 12. The card blocks 13 drive the connecting rod 14 to slide inside the arc groove 15. The two card blocks 13 stretch the spring 20, and the card blocks 13 are separated from the card groove 16, which is convenient for releasing the card connection between the connecting column 8 and the reflector mounting seat 10, and is convenient for disassembling and cleaning the thermal radiation reflector 11 to prevent excessive dust from accumulating on the surface of the thermal radiation reflector 11 and affecting the reflective effect of the thermal radiation reflector 11.

[0037] Furthermore, by engaging the card block 13 with the card slot 16, it is convenient to disassemble and clean the reflective screen mounting base 10 and the thermal radiation reflective screen 11. After the thermal radiation reflective screen has been used for a long time, a certain amount of dust may accumulate on the surface of the thermal radiation reflective screen 11. Disassembling and cleaning the thermal radiation reflective screen 11 can maintain the cleanliness of the surface of the thermal radiation reflective screen 11, ensure effective reflection of thermal radiation, enhance the reflection effect of the thermal radiation reflective screen 11, and extend its service life.

[0038] By adjusting the angle of the thermal radiation reflecting screen 11, it is convenient to change the inclination angle of the thermal radiation reflecting screen 11 and the sun, so as to reflect the thermal radiation generated by the sun, and improve the reflection effect of the thermal radiation reflecting screen 11 on thermal radiation. When the angle of the thermal radiation reflecting screen 11 changes, the direction of the reflected thermal radiation will also change accordingly, which can make more heat be reflected to where it is needed, or reduce the heat transfer to unnecessary areas, and prevent excessive impact on other areas.

[0039] Working principle: when using the reflective screen, install the reflective screen at a high place of the equipment. In daily production and life, especially for outdoor equipment, the main heat source is generated by the sun. When the equipment is exposed to the sun, especially in hot summer, install the reflective screen at a high place of the equipment to reflect the thermal radiation. Start the drive motor 5 to drive the worm 6 to rotate, the worm 6 drives the worm wheel 7 to rotate, the worm wheel 7 drives the first rotating shaft 4 and the connecting column 8 to rotate, the connecting column 8 drives the reflective screen mounting seat 10, the thermal radiation reflective screen 11, the second rotating shaft 12, the block 13, the connecting rod 14, the arc groove 15 and the groove 16 to rotate, and adjust the angle of the thermal radiation reflective screen 11 to facilitate the adjustment of the angle between the thermal radiation reflective screen 11 and the sun, so as to reflect the thermal radiation generated by the sun.

[0040] By using the weft 17, the warp 18 and the aluminum foil 19, it is convenient to improve the reflectivity of thermal radiation. Since the weft 17 and the warp 18 are both glass fiber yarns, the glass fiber yarns have a high reflectivity and can reflect most of the radiant heat back to the heat source, thereby improving the reflection efficiency of thermal radiation. The aluminum foil 19 can also protect against thermal radiation. The aluminum foil 19 can reflect and absorb thermal radiation, thereby preventing it from continuing to be transmitted to the protected object.

[0041] When the reflector is used for a long time, the surface of the thermal radiation reflector 11 will absorb a certain amount of dust, and it needs to be cleaned regularly. In order to improve the reflective effect of the thermal radiation reflector 11, the thermal radiation reflector 11 is usually installed at a high place of the equipment. Due to the high position of the thermal radiation reflector 11, it is not convenient to disassemble and clean it. At this time, you only need to pull the card blocks 13 to both ends to make the card blocks 13 rotate around the second rotating shaft 12. The card blocks 13 drive the connecting rod 14 to slide inside the arc groove 15. The two card blocks 13 stretch the spring 20, and the card blocks 13 are separated from the card groove 16, which is convenient for releasing the card connection between the connecting column 8 and the reflector mounting seat 10, and is convenient for disassembling and cleaning the thermal radiation reflector 11 to prevent excessive dust from accumulating on the surface of the thermal radiation reflector 11 and affecting the reflective effect of the thermal radiation reflector 11.
