[0026] Embodiment 1:

[0027] In view of the problem that the external wall sunshade device in the prior art only has the function of sunshading, which leads to the waste of light energy, it is considered to use the sunshade and its installation structure as a channel for water circulation, and use the heat energy of sunlight to heat the water supply of the building while providing sunshade. Figure 1 As shown, a preferred embodiment of an exterior wall sunshade device described in the utility model is a device comprising an exterior wall 1, a plurality of sunshades 2 spaced apart outside the exterior wall 1, at least two pipes 3 are provided on the exterior wall 1, a flow channel 4 is provided inside the sunshade 2, movable joints 5 connected to the flow channel 4 and the two pipes 3 are provided above and below the sunshade 2, respectively, the movable joints 5 can rotate axially relative to the pipes 3, a driving arm 6 is provided on the movable joint 5, the driving arms 6 of the plurality of sunshades 2 are hinged with a connecting member 7, and traction mechanisms 8 are provided on both sides of the connecting member 7.

[0028] The above-mentioned exterior wall shading device can drive the driving arm 6 through the connecting piece 7 through the traction mechanism 8, and then drive the movable joint 5 to rotate around the axial direction relative to the pipe fitting 3, so as to realize the deflection of the sun visor 2 relative to the pipe fitting 3, to change the direction of the sun visor 2 and the distance between adjacent sun visors 2, to adapt to the direction of sunlight incidence to improve the shading effect, and also meet the ventilation requirements; at the same time, the building water supply can be introduced into the pipe fitting 3 connected to the movable joint 5 below the sun visor 2, so that the water flow fills the internal flow channel 4 of the sun visor 2, and then is discharged from the pipe fitting 3 connected to the movable joint 5 above the sun visor 2, and the heat energy absorbed by the light of the sun visor 2 is exchanged with the internal water to heat the water supply for the building, thereby achieving the purpose of energy saving and emission reduction, thereby solving the problem of light energy waste in the prior art and meeting the application requirements of green buildings.

[0029] Further, such as Figure 2 As shown, a supporting keel 9 is provided on the outer wall 1, and brackets 10 are provided between the two pipe fittings 3 and the supporting keel 9 respectively. The installation position and angle of the sun visor 2 can be further adjusted by supporting and installing the pipe fittings 3 through the brackets 10 to further meet the reference requirements of the building.

[0030] Furthermore, a reflective film 11 corresponding to the sun visor 2 is provided on the exterior wall 1. The reflective film 11 can be attached to the window glass of the exterior wall 1 in the form of a transparent film, or can be attached to the surface of the exterior wall 1 in a small area. When the sun visor 2 is deflected and there is a gap between adjacent sun visors 2, the light leaking through the gap or reflected by the sun visor 2 is reflected onto the sun visor 2, thereby further increasing the sunshade and building water supply heating effects.

[0031] Furthermore, the plurality of sun visors 2 include at least one row, and at least two pipe fittings 3 are respectively located above and below each row of sun visors 2. The top pipe fitting 3 is connected to a water outlet pipe 12, and the pipe fitting 3 below each row of sun visors 2 is connected to a solenoid valve 13. The solenoid valve 13 can be used to control the opening and closing and flow rate of the pipe fitting 3. For example, the flow rate can be reduced when the sunlight is not strong, and the flow rate can be increased when the sunlight is strong.

[0032] Furthermore, a flow meter 14 is provided on the water outlet pipe 12 or the pipe fitting 3, and the flow meter 14 can be used to monitor the flow rate.

[0033] Furthermore, it includes a water tank 15, and the water tank 15 is connected to a water pump 16. The water pump 16 is connected to the pipe fitting 3 under each row of sun visors 2, and the water outlet pipe 12 is connected to the water tank 15. After cold water is injected into the water tank 15, the water in the water tank 15 is pumped to the pipe fitting 3 under the sun visor 2 through the water pump 16. After the water is heated, its specific gravity decreases and it is easier to rise and enter the water tank 15 from the water outlet pipe 12, which can increase the circulation of water and make the water temperature rise to a certain stability. The hot water in the water tank 15 is then used for water supply in the building, and the structure is simpler.

[0034] Furthermore, the traction mechanism 8 includes a traction rope 81, a guide wheel 82 and a reel 83. One end of the traction rope 81 is connected to the connecting member 7, and the other end of the traction rope 81 is connected to the reel 83 by passing around the guide wheel 82. The guide wheel 82 can prevent the traction rope 81 from detaching from the reel 83. The reel 83 can be wound to pull the traction rope 81, thereby pulling the connecting member 7 and driving the drive arm 6 to deflect.

[0035] Furthermore, there are at least two connecting members 7 which are respectively connected to the driving arms 6 above and below the sun visor 2, and there are multiple traction ropes 81 which are connected to the same side of multiple connecting members 7, so that the traction mechanism 8 on the same side can simultaneously pull the driving arms 6 above and below the sun visor 2, further improving the stability of the sun visor 2.

[0036] The deflection principle of the sunshade 2 of the above-mentioned exterior wall sunshade device is as follows: Figure 3 As shown:

[0037] like Figure 3 As shown in (a), when the sun is shining directly, the traction mechanism 8 on the left and right sides can be adjusted to make the sun visor 2 perpendicular to the sun; Figure 3 As shown in (b), when the sun shines from the right side, the traction mechanism 8 on the left side, i.e., the wire reel 83, can be wound up, and the traction mechanism 8 on the right side, i.e., the wire reel 83 can be unwound. Then, the connecting member 7 moves to the left while driving the driving arms 6 of the plurality of sun visors 2 to deflect to the left around the axis of the movable joint 5, so that the plurality of sun visors 2 are synchronously deflected toward the sun. Similarly, Figure 3As shown in (c), when sunlight shines from the left side, the cable can be wound up through the traction mechanism 8 on the right, i.e., the cable reel 83, and unwound through the traction mechanism 8 on the left, i.e., the cable reel 83. Then, the connecting member 7 moves to the right while driving the driving arms 6 of the plurality of sun visors 2 to deflect to the right around the axial direction of the movable joint 5, so that the plurality of sun visors 2 are synchronously deflected toward the sunlight. The synchronous deflection of the plurality of sun visors 2 can be achieved by using two traction mechanisms 8, which can simplify the adjustment drive, especially for large-area sunshades, reduce costs, and facilitate practical use.

[0038] Embodiment 2:

[0039] Based on the same inventive concept, Figure 4 As shown, another preferred embodiment of an exterior wall shading device described in the utility model is different from Example 1 in that a plurality of sunshades 2 are arranged in multiple rows, and the movable joints 5 below the upper row of sunshades 2 are connected to the same pipe 3 as the movable joints 5 above the lower row of sunshades 2, so the number of installed pipes 3 can be saved, and the solenoid valve 13 is used to control the water inlet flow of each row of sunshades 2, and the adjustable drive of large-area sunshades can be realized to meet the application requirements of green buildings.
