Example Embodiment

[0017] Example 1

[0018] See the drawings, the present invention has a box body 1, a vacuum tube 2, a condenser 3 and a sunshade device 5. The vacuum tube 2 and the condenser 3 are arranged in the box body 1, and the condenser 3 is located at the back of the vacuum tube 2. A toughened glass 4 is installed on the front of the body 1, and the sunshade device 5 is arranged in the box 1 and between the vacuum tube 2 and the toughened glass 4.

[0019] The sunshade device 5 includes a reduction motor 5-1, a roller blind shaft 5-2, and a sunshade 5-3. The roller blind shaft 5-2 of the sunshade device 5 is located on the left and right sides of the box. In the embodiment, the roller blind shaft 5-2 is on the left side of the box. A support frame 1-1 is fixed on the upper and lower ends of the left box wall, a motor seat 1-2 is also fixed on the lower end, and the upper and lower ends of the right box wall opposite to the roller shutter shaft 5-2 are respectively fixed A pulley fixing f...

Abstract

The invention discloses a sun-shading vacuum tube flat plate collector, which comprises a box body, a vacuum tube, a condenser and a sun-shading device, wherein the vacuum tube and the condenser are arranged in the box body; the condenser is positioned on the back side of the vacuum tube; a piece of toughened glass is arranged on the front side of the box body; the sun-shading device is arranged in the box body and positioned between the vacuum tube and the toughened glass, and comprises a reducing motor, a rolling blind shaft, a roller and a sun-shading curtain; one end of the sun-shading curtain is fixed on the rolling blind shaft, and a tractive pipe is fixed at the other end of the sun-shading curtain; a guide wheel is fixed at two ends of the tractive pipe respectively; a tractive rope is arranged on the upper side and the lower side in the box body respectively; one end of the tractive rope is fixed on the roller; and the tractive rope is turned after passing through a fixed pulley and the guide wheel on the same side of the tractive rope and then is connected with the tractive rope on the opposite side through a spring. The sun-shading device of the sun-shading vacuum tube flat plate collector is simple in structure, can be rolled smoothly and is difficult to damage.

Description

technical field [0001] The invention relates to a sunshade vacuum tube flat plate heat collector. Background technique [0002] Chinese patent No. 201020196999.9 utility model patent specification discloses a tube-type flat solar collector, which has a row of heat-pipe vacuum tubes. Toughened glass is installed on the front side; the heat pipe type vacuum tube and the concentrator are all in the box body, the water pipe passes through the box body, the heat pipe condensation section of the vacuum tube is inserted into the water pipe and is sealed with the water pipe, and the longitudinal ends of the box body are respectively equipped with There are heat shields surrounding the corresponding ends of the heat pipe vacuum tubes. The above-mentioned utility model adopts a closed-circuit pressure-bearing system, which uses heat medium to heat water. If the sunlight is too strong, the pressure in the system will rise. When the pressure reaches a certain level, the safety valve wi...
