[0036] Example 1

[0037] Reference Figure 1-7 A passive house exterior wall thermal insulation system is used in the field of passive house exterior walls, comprising: an inner wall panel 1, on which a waterproof layer 2, a thermal insulation layer 3, a heat insulation layer 4 and an outer wall panel 5 are arranged from right to left. The waterproof layer 2 is made of a mortar waterproofing agent to prevent water penetration; the thermal insulation layer 3 is made of a rock wool thermal insulation board with excellent thermal insulation performance; the heat insulation layer 4 is made of glass fiber, which can effectively isolate heat transfer; and the outer wall panel 5 is the outermost structure to provide protection.

[0038] On one side of the outer wall panel 5, a mounting groove 14 is designed, in which a heat collecting layer 11 is arranged. The heat collecting layer 11 is made of phenolic foam and can effectively collect solar heat. In addition, a connecting pipe 13 is arranged on the waterproof layer 2, the thermal insulation layer 3, the heat insulating layer 4 and the outer wall panel 5. One end of the connecting pipe 13 is connected to the mounting groove 14, and the other end runs through one side of the inner wall panel 1 for the circulation of air or heat. In order to increase efficiency, two such connecting pipes 13 are arranged.

[0039] On the inner wall of the mounting groove 14, a transparent glass 6 is fixedly installed to allow sunlight to enter and shine on the heat collecting layer 11. At the same time, a groove 7 connected to the mounting groove 14 is also provided on the exterior wall panel 5 for installing a cleaning mechanism and a removal mechanism.

[0040] The cleaning mechanism includes a motor 17, a reciprocating screw 9, a moving block 10, a moving box 8 and a plurality of bristles 12. The motor 17 drives the reciprocating screw 9 to rotate, and through the threaded connection between the screw nut and the reciprocating screw 9, drives the moving block 10 to reciprocate in the groove 7. The moving box 8 fixed at the bottom of the moving block 10 is equipped with bristles 12, which fit against one side of the transparent glass 6 to sweep away dust and snow.

[0041] The cleaning mechanism includes a box body 15, two synchronous wheels 20, a second rotating rod 19, a mounting plate 21 and two blades 23. The second rotating rod 19 is connected to the reciprocating screw 9 through a synchronous belt 28 to achieve synchronous rotation. The second rotating rod 19 and the two first rotating rods 27 are respectively equipped with a second bevel gear and a first bevel gear 22, which realize power transmission through meshing. When the second rotating rod 19 rotates, it will drive the two blades 23 to rotate and generate wind. The wind enters the mobile box 8 through the telescopic hose 16 and blows to the transparent glass 6 through the blowing hole 24 to help remove snow and dust.

[0042] Example 2

[0043] On the basis of the first embodiment, the second embodiment further includes:

[0044] Reference Figure 1-7 An electric heating plate 18 is added in the box body 15 to heat the air in the box body 15, so as to blow out hot air, further improving the effect of removing snow and dust.

[0045] A rubber plug 25 is provided at one end of the connecting pipe 13 to seal the connecting pipe 13 when not needed to prevent outside air or moisture from entering. A pull ring 26 is also provided at one end of the rubber plug 25 to facilitate user pulling.

[0046] A slide groove is provided at the top of the groove 7, and a sliding block matching the slide groove is provided at the top of the moving block 10, thereby reducing the friction force of the moving block 10 during the movement process and improving the operation efficiency of the cleaning mechanism.

[0047] Example 3

[0048] On the basis of the first embodiment, the third embodiment further includes:

[0049] Reference Figure 1-3 The material selections of the waterproof layer 2, the thermal insulation layer 3, the heat insulating layer 4 and the heat collecting layer 11 are all based on their excellent performance and applicability, ensuring the stability and efficiency of the entire system.

[0050] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 17 and the electric heating plate 18 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0051] The working principle and use process of this technical solution are as follows: when there is sunshine during the daytime in winter, the rubber plugs 25 are taken out from the two connecting pipes 13 respectively. When the sunlight shines on the heat collecting layer 11 through the transparent glass 6, the heat collecting layer 11 absorbs the heat in the sunlight so that its temperature rises rapidly, thereby heating the air between the heat collecting layer 11 and the transparent glass 6 to produce a greenhouse effect. Through the connecting pipe 13, convection heating can be provided to the room. When dust or snow accumulates on the transparent glass 6, the motor 17 is started. The motor 17 drives the reciprocating screw 9 to rotate, and the moving block 10 reciprocates in the groove 7 through the threaded connection between the screw nut and the reciprocating screw 9. The moving block 10 drives the moving box 8 and the bristles 12 to move, and the bristles 12 fit on one side of the transparent glass 6 to sweep away the dust and snow, thereby sweeping away the dust and snow on the transparent glass 6 and improving the absorption effect of the heat collecting layer 11.

[0052] At the same time, the second rotating rod 19 rotates synchronously with the reciprocating screw 9 through the synchronous belt 28, driving the blades 23 on the two first rotating rods 27 to rotate. The blades 23 inhale air through the air inlet hole, blow the air into the moving box 8 through the telescopic hose 16, and finally blow it out from the blowing hole 24 to form an airflow to help remove the residue on the transparent glass 6, so that the dust and snow on the transparent glass 6 can be removed. If it is necessary to blow out hot air, the electric heating plate 18 can be started to heat the air in the box body 15, and then blow out hot air to further help remove snow and melt frost. After the moving box 8 is used, it can be driven into the groove 7 by the motor 17, and the transparent glass 6 will not be blocked.

[0053] In winter nights, the rubber plug 25 is inserted into the connecting pipe 13 to block it. The heat stored in the wall itself can be used to radiate heat to the room. The heat radiated from the wall to the room heats the air near the wall, and the heated airflow and the indoor airflow are convected to heat the room. In summer, the user can block the connecting pipe 13 with the rubber plug 25 to prevent the outside heat from entering the room.

[0054] The heat collecting layer 11 is phenolic foam (phenolic foam is a closed-cell rigid foam plastic made of phenolic resin and emulsifiers, curing agents, foaming agents and other additives, which is foamed and cured through a scientific formula. It is known as the king of insulation due to its extremely low thermal conductivity and good thermal insulation performance), and the waterproof layer 2 is a mortar waterproofing agent. The waterproof layer 2 can prevent external rainwater from penetrating into the inner wall panel 1 and causing corrosion to the inner wall panel 1.

[0055] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
