[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4The present utility model provides a technical solution: a high-efficiency, energy-saving building window insulation device comprising an insulation frame 1, which is rectangular with an open end. A first groove 2 is defined in the left inner wall of the insulation frame 1. A rotating shaft 301 is rotatably mounted between the upper and lower ends of the first groove 2 via torsion springs 4 and bearings. The torsion springs 4 enable the rotating shaft 301 to automatically rotate, thereby facilitating the automatic retraction of the insulation cloth 3. The insulation cloth 3 is wound around the shaft surface of the rotating shaft 301. The insulation cloth 3 is made of an insulating material, such as a sunscreen coating, and can effectively absorb and reflect strong sunlight. Two second grooves 6 are respectively provided on the upper and lower side walls of the inner cavity of the heat insulation frame 1. The left and right ends of the bidirectional screw 13 are respectively mounted on the two side walls of the groove cavity of the second groove 6 at the top via bearings. The left and right ends of the guide rod 7 are respectively welded to the two side walls of the groove cavity of the second groove 6 at the bottom. The movable block 8 is movably sleeved on the rod surface of the guide rod 7. The screw block 14 is screwed on the rod surface of the bidirectional screw 13. The upper and lower ends of the connecting frame 9 are respectively welded between the adjacent side walls of the screw block 14 and the movable block 8. The purpose is to enable the screw block 14 and the movable block 8 to move horizontally back and forth together under the action of the guide rod 7 when the bidirectional screw 13 rotates, thereby driving the connecting frame 9 to move horizontally back and forth together. A first motor 12 is fixed to the left side wall of the top of the heat insulation frame 1 via bolts and is connected to the left end of the bidirectional screw 13 via a coupling. The purpose is to drive the bidirectional screw 13 to rotate. The front and rear side walls of the connecting frame 9 are respectively provided with a pressing assembly and a cleaning assembly. By setting the pressing assembly, the insulation cloth 3 can be pressed against the front side wall of the connecting frame 9. When the window needs to be insulated, the first motor 12 is started to make the connecting frame 9 pull the insulation cloth 3 from the left side to the right side, thereby unfolding the insulation cloth 3, so that the insulation cloth 3 blocks the sunlight from the window, reflects and absorbs the heat brought by the sunlight, and achieves the effect of insulating the window. When insulation is not needed, the insulation cloth 3 can be taken out from under the pressing assembly. Under the action of the torsion spring 4, the rotating shaft 301 automatically reels the insulation cloth 3, which is very convenient.

[0022] The pressing assembly includes a pressing groove 10 provided on the front side wall of the connecting frame 9 , and the pressing groove 10 is used for placing the thermal insulation cloth 3 to be pressed. The upper and lower ends of the compression groove 10 are provided with mounting brackets 11 welded to the surface of the connecting bracket 9. The middle plate body of the extrusion plate 15 is rotatably connected to the frame body of the mounting bracket 11 via the pinion. A spring 16 is welded between the outer end plate body of the extrusion plate 15 and the frame body of the connecting bracket 9. The inner end plate body of the extrusion plate 15 is welded with a compression column 17, and the column body of the compression column 17 can be inserted into the groove cavity of the compression groove 10. The end away from the center of the clamping cavity of the two extrusion plates 15 is the outer end, and the opposite is the inner end. Under the action of the compression assembly, the outer end of the extrusion plate 15 can be pressed in advance, so that the inner end of the extrusion plate 15 can drive the compression column 17 to tilt, thereby placing the thermal insulation cloth 3 in the compression groove 10. Loosening the extrusion plate 15 can make the compression column 17 automatically reset under the action of the spring 16 to compress the thermal insulation cloth 3 located in the compression groove 10, thereby fixing one end of the thermal insulation cloth 3, and then the thermal insulation cloth 3 is driven to unfold by the connecting bracket 9. The cleaning assembly includes two rectangular plates 18 welded to the rear side walls of the connecting frame 9. The inner side walls of the two rectangular plates 18 are rotatably connected to the mounting plates 20 via bearings. A brush roller 21 and a liquid spray pipe 22 are welded between the adjacent side walls of the two mounting plates 20. A second motor 19 is fixed to the wall of the upper rectangular plate 18 via bolts. The output end of the second motor 19 is connected to the shaft end of the upper mounting plate 20 via a coupling. The purpose is to facilitate the rotation of the mounting plate 20 and thereby control the use sequence of the brush roller 21 and the liquid spray pipe 22. A connecting groove 25 is provided inside the liquid spray pipe 22, and liquid spray holes 23 connected to the connecting groove 25 are uniformly provided on the surface of the liquid spray pipe 22. A liquid injection hole 24 connected to the connecting groove 25 is provided on one side wall of the end of the liquid spray pipe 22. The purpose is to allow the liquid injection hole 24 to be externally connected to a cleaning liquid delivery device so that the cleaning liquid passes through the connecting groove 25 and is sprayed from the liquid spray hole 23 onto the window surface. Fixing plates 5 are welded at the four corners of the heat insulation frame 1 to facilitate fixing the heat insulation device at a designated position.

[0023] When the window needs to be cleaned, first control the second motor 19 to drive the mounting plate 20 to rotate, so that the side where the spray pipe 22 is located is close to the window, thereby spraying cleaning liquid onto the window through the spray hole 23, and then control the second motor 19 to rotate the mounting plate 20, so that the side where the brush roller 21 is located is close to the window. As the first motor 12 drives the bidirectional screw rod 13 to rotate, under the action of the guide rod 7, movable block 8, screw block 14 and connecting frame 9, the brush roller 21 is driven to brush the surface of the window back and forth, thereby cleaning the dust and dirt on the surface of the window to prevent it from being affected by excessive accumulation of dust and dirt.
