[0024] In an optional embodiment of the present invention, a main channel 29 is provided on the cleaning strip 26, and the inner wall of the main channel 29 is connected to the outer wall of the cleaning strip 26 where the cleaning layer 36 is located through a branch channel 37.

[0031] In an optional embodiment of the present invention, the inner cavity of the heat recovery device 7 is filled with clean water, and the inner wall of the inner cavity of the heat recovery device 7 is provided with a heat conductive layer, which is connected to the first heat conductive pipe 5. The heat conductive layer helps to quickly absorb heat and transfer heat to the clean water.

[0032] Implementation process: The present invention can be used in infrastructure construction.

[0033] When the sound waves of external noise are transmitted to the sound-absorbing cotton, since the sound-absorbing cotton usually has a large number of fiber structures inside, these fibers are intertwined to form a complex network. The sound waves will cause the fibers to vibrate. During the vibration process, the fibers use their damping characteristics to convert the energy of the sound waves into heat energy and consume it, thereby absorbing noise and ensuring indoor auditory comfort.

[0034] When the external ambient temperature is too high, the external heat will be transferred to the wall body 1, and the centrifugal pump 8 will be turned on. The driving component in the centrifugal pump 8 will drive the impeller component and the first gear 9 to rotate, thereby driving the coolant in the first heat pipe 5 and the second heat pipe 6 to flow through centrifugal force. The coolant absorbs part of the heat on all the wall bodies 1 and transfers the heat to the heat recovery device 7 for heat recovery. The heat recovery device 7 transfers the heat to the clean water inside to heat the clean water for use by indoor personnel.

[0035] When it is necessary to wipe and clean the glass window 35, the electromagnet 14 is turned on to generate a magnetic repulsive force, which repels the permanent magnet 13, causing the gear plate 11 and the second gear 12 to overcome the elastic force of the first spring 15 and move upward until the second gear 12 is engaged with the first gear 9 and the third gear 16 at the same time. The first gear 9 drives the second gear 12, the third gear 16, the first worm gear 17, and the first worm 18 to rotate rapidly. After the first worm 18 is decelerated by the reducer 19, the second worm gear 20 rotates slowly, thereby driving the second worm gear 24, the first sprocket 21, the second sprocket 22, and the first chain 23 to rotate. The second sprocket 22 will drive the first sprocket 21 on the adjacent wall body 1 to move through the liquid tank 34, and the transmission block 25 moves along the trajectory of the first chain 23, thereby driving the two extension bars 28 and the cleaning bar 26 to move back and forth left and right, turning on the liquid pump in the heat recovery device 7 to extract the clean water in the heat recovery device 7, thereby Clean water enters the main channel 29 through the elastic telescopic liquid tube 27 and is then sprayed onto the cleaning layer 36 through the branch channel 37. The cleaning layer 36 is moistened with clean water and then wipes the glass window 35. The elastic telescopic liquid tube 27 can be elastically extended and retracted without affecting the movement of the cleaning strip 26. When the cleaning strip 26 moves to the right until the push-type nozzle 33 is inserted into the liquid adding channel 31, the liquid adding channel 31 pushes the one-way valve 30 to open, thereby releasing the one-way valve 30 from sealing the liquid adding channel 31. The push-type nozzle 33 is blocked, and the push-type nozzle 33 extends into the main channel 29. The cleaning strip 26 continues to move to the right. The right wall of the cleaning strip 26 pushes the push-type nozzle 33 to press, so that the cleaning liquid in the extension strip 28 is sprayed into the main channel 29 through the push-type nozzle 33 and mixed with clean water, thereby improving the cleaning and disinfection ability of the glass window 35. After the cleaning strip 26 moves to the left, the push-type nozzle 33 will be separated from the liquid adding channel 31, and the one-way valve 30 is reset under the action of elastic force to re-block the liquid adding channel 31.

[0036] The present invention realizes heat energy communication and recovery between walls by fixing multiple wall bodies 1 to each other and cooperating with a first heat conducting pipe 5, a second heat conducting pipe 6, a heat recovery device 7 and a centrifugal pump 8. The centrifugal pump 8 is provided with a drive assembly and an impeller assembly. After startup, it can quickly circulate the coolant and promptly transfer the heat on the wall to the heat recovery device 7, so that the heat is converted and stored in the internal clean water. This can not only controllably adjust the temperature of the wall body 1 to achieve thermal insulation, but also provide usable heat energy for the room, with the advantages of high energy efficiency, energy saving and environmental protection. The window channel 2 is equipped with a glass window 35. The transmission groove 3 at the bottom cooperates with the sprocket chain mechanism. The window surface cleaning operation can be carried out by the power system driven by the centrifugal pump 8, avoiding the safety risks caused by manual scrubbing. The cleaning strip 26 is provided with a cleaning layer 36, which is soft and conforms to the glass surface and can effectively remove dust and dirt during the reciprocating motion. The cleaning strip 26 is driven by the transmission block 25 to realize automatic cleaning of the window surface, improving the convenience of operation and cleaning efficiency. The heat recovery device 7 is equipped with a liquid pump and an elastic telescopic liquid pipe 27, which makes the liquid delivery process flexible and reliable. The elastic telescopic liquid pipe 27 has good telescopic adaptability during the movement of the cleaning strip 26 and does not affect the operation of the movement mechanism. Cleaning liquid is automatically injected from the liquid tank 34 into the main channel 29 via the push-type nozzle 33. After mixing with clean water, it is sprayed onto the cleaning layer 36, enhancing the sterilization effect during the window cleaning process. The main channel 29 is equipped with a one-way valve 30 and a buffer layer 32 to effectively prevent liquid backflow and spray impact during the liquid filling process, improve the sealing performance, and ensure safe and stable operation of the system. In addition, the sound insulation cotton has honeycomb holes and the sound-absorbing cotton is made of glass fiber, which can effectively reduce the transmission of external noise, has good sound absorption and sound insulation effects, and improves the comfort of the living or office environment; In summary, the present invention integrates multiple functions such as thermal insulation, heat recovery, intelligent cleaning and sound insulation. It has a reasonable structure and a high degree of automation. It is suitable for modern infrastructure renovation and construction, and has significant application value in improving building energy conservation and intelligent management.
