[0026] As Figures 1-7 shown, a glass surface cleaning device for construction of the present utility model includes an active suction cup 1 and a driven suction cup 2. Cleaning scrapers 3 are connected to the side walls of the active suction cup 1 and the driven suction cup 2 facing each other. The glass is clamped between the cleaning scraper 3 of the active suction cup 1 and the cleaning scraper 3 of the driven suction cup 2. The cleaning scraper 3 abuts against the glass. A fixed magnet plate 4 is fixedly connected to the side wall of the driven suction cup 2 facing away from the cleaning scraper 3. A handle 15 is fixedly connected to the side wall of the active suction cup 1 facing away from the cleaning scraper 3. A rubber sleeve 16 is fixedly connected to the handle 15. Anti-slip patterns are provided on the outer wall of the rubber sleeve 16. Safety ropes 14 are fixedly connected to both the active suction cup 1 and the driven suction cup 2. A connection groove 201 is provided on the side wall of the driven suction cup 2 facing away from the cleaning scraper 3. The fixed magnet plate 4 is fixedly connected in the connection groove 201. A movable magnet assembly 5 is connected to the side wall of the active suction cup 1 facing away from the cleaning scraper 3. The movable magnet assembly 5 includes a connection frame 6 and a movable magnet plate 8. The connection frame 6 is a rectangular frame. The connection frame 6 is fixedly connected to the side wall of the active suction cup 1. The movable magnet plate 8 is a rectangular plate. Rotating shafts 801 are fixedly connected to the middle positions of the two side walls along the length direction of the movable magnet plate 8. The rotating shafts 801 extend out of the movable magnet plate 8. Fixed seats 13 are fixedly connected to the two symmetric inner walls inside the connection frame 6. The two rotating shafts 801 are respectively rotatably connected to the two fixed seats 13. The movable magnet plate 8 faces the fixed magnet plate 4. The movable magnet plate 8 is parallel to the fixed magnet plate 4. The movable magnet plate 8 and the fixed magnet plate 4 are magnetically attracted to each other.

[0027] When the utility model is in use, since the movable magnet plate 8 and the fixed magnet plate 4 attract each other magnetically, the active suction cup 1 and the driven suction cup 2 are stably clamped on both sides of the glass. At this time, moving the active suction cup 1 through the handle can drive the driven suction cup 2 to move synchronously, so as to realize the cleaning of the glass by the cleaning squeegee 3. When in use, water or cleaning agent can be sprayed on the glass and the cleaning squeegee 3 to improve the cleaning effect. When it is necessary to separate the active suction cup 1 and the driven suction cup 2 after cleaning, rotate the movable magnet plate 8 to reverse the magnetic pole of the movable magnet plate 8, so that the movable magnet plate 8 repels the fixed magnet plate 4 magnetically, and the active suction cup 1 and the driven suction cup 2 can be easily separated, without the need to use great force to pull the active suction cup 1 and the driven suction cup 2 or force the active suction cup 1 and the driven suction cup 2 to be misaligned, ensuring that the glass will not be damaged or misaligned, reducing the labor intensity of the staff and improving the work efficiency.

[0028] The settings of the handle 15 and the rubber sleeve 16 facilitate the staff to hold, and the anti-slip lines on the outer wall of the rubber sleeve 16 can increase the friction, which is helpful for use.

[0029] The setting of the safety rope 14 improves the use stability of the utility model. When in use, the end of the safety rope 14 far from the active suction cup 1 or the driven suction cup 2 is fixedly connected to other fixed components, so as to prevent the equipment from being damaged or causing a smashing accident after the active suction cup 1 or the driven suction cup 2 accidentally detaches.

[0030] Two movable magnet plates 8 form a magnet pair 7. The two movable magnet plates 8 in a magnet pair 7 are symmetrical, there is a gap between the mutually approaching sides of the two movable magnet plates 8 in a magnet pair 7, and the two movable magnet plates 8 in a magnet pair 7 are both rotatably connected inside the connecting frame 6 through the fixed seat 13.

[0031] There are multiple magnet pairs 7, and the multiple magnet pairs 7 are linearly arranged locally along the width direction inside the connecting frame 6.

[0032] The settings of the multiple magnet pairs 7 and the two movable magnet plates 8 included in each magnet pair 7 are to increase the magnetic force between the movable magnet plate 8 and the fixed magnet plate 4, so as to make the clamping of the glass by the active suction cup 1 and the driven suction cup 2 more stable.

[0033] There is a gap between the mutually approaching sides of the two movable magnet plates 8 in a magnet pair 7 to ensure that the movable magnet plate 8 does not collide and interfere when rotating. Similarly, there should also be a gap between the mutually approaching sides of the two adjacent movable magnet plates 8 between the two magnet pairs 7.

[0034] In addition, when the movable magnet plate 8 rotates, it is necessary to consider that the edge of the movable magnet plate 8 should not collide with the inner wall of the connecting frame 6 and the side wall of the active suction cup 1 during the rotation of the movable magnet plate 8. Therefore, the height of the connecting frame 6 should be set appropriately, and a gap should also be provided between the inner wall of the connecting frame 6 and the movable magnet plate 8 arranged near the inner wall of the connecting frame 6. In the present utility model, the rotating shaft 801 is arranged at the middle position of the side wall of the movable magnet plate 8, which minimizes the radius required for the rotation of the movable magnet plate 8, effectively reducing the height of the connecting frame 6 and making the distance between the movable magnet plate 8 and the fixed magnet plate 4 as close as possible, thereby ensuring the use stability.

[0035] The present utility model is provided with a rotatably connected movable magnet plate 8 to achieve magnetic attraction and magnetic repulsion between the movable magnet plate 8 and the fixed magnet plate 4. Since gaps need to be considered and provided between the movable magnet plates 8 and between the movable magnet plate 8 and other components, there is a problem that the rotation of the movable magnet plate 8 cannot be limited during use. If the movable magnet plate 8 accidentally flips during use, it will affect the normal use of the present utility model. To solve this technical problem, the present utility model is provided with a limiting component connected between two movable magnet plates 8 in each magnet pair 7. The limiting component includes a limiting column 9, a guiding sliding plate 10, a support cylinder 11 and a spring 12. The top surface of the support cylinder 11 is provided with a top plate, and a top hole 1101 is provided at the center of the top plate of the support cylinder 11. The bottom surface of the support cylinder 11 is an opening. A blind hole 101 is provided on the side wall of the active suction cup. The bottom end of the support cylinder 11 is fixedly connected in the blind hole 101. A bottom hole 901 is provided at the center of the bottom surface of the limiting column 9. A through hole 1001 is provided at the center of the guiding sliding plate 10. The guiding sliding plate 10 is fixedly connected to the bottom end of the limiting column 9. The through hole 1001 is coaxial with the bottom hole 901. The outer wall of the guiding sliding plate 10 is smaller than the inner diameter of the support cylinder 11, the outer wall of the guiding sliding plate 10 is larger than the outer wall of the limiting column 9, the outer wall of the limiting column 9 is smaller than the inner diameter of the top hole 1101. The guiding sliding plate 10 is slidably connected inside the support cylinder 11, the limiting column 9 is slidably connected in the top hole 1101, the upper part of the limiting column 9 extends out of the hole 1101, the spring 12 is connected in the bottom hole 901, and the two ends of the spring 12 are respectively abutted against the inner bottom surface of the bottom hole 901 and the inner bottom surface of the blind hole 101. The limiting column 9 is a cylinder. Limiting grooves 802 are provided on the two side walls of each movable magnet plate 8 where the rotating shaft 801 is not provided. The limiting grooves 802 are arc grooves. One of the two limiting grooves 802 of each movable magnet plate 8 abuts against the outer wall of the limiting column 9. The number of limiting components is the same as the number of magnet pairs 7, and the number of the blind holes 101 is the same as the number of limiting components.

[0036] When the active suction cup 1 and the driven suction cup 2 hold the glass for normal use, the limiting grooves 802 of the two movable magnet plates 8 in each magnet pair 7 are clamped on the outer wall of the limiting post 9, thereby realizing the limitation of the movable magnet plate 8 and preventing the movable magnet plate 8 from accidentally flipping. When it is necessary to separate the active suction cup 1 and the driven suction cup 2 after use, use a tool or finger to press the top surface of the limiting post 9, so that the limiting post 9 compresses the spring 12 and leaves the limiting groove 802. At this time, the movable magnet plate 8 can be rotated. After the movable magnet plate 8 rotates one circle, the limiting groove 802 on the other side wall of the movable magnet plate 8 will be clamped into the limiting post 9 again.

[0037] Limiting components are arranged between the two movable magnet plates 8 in each magnet pair 7 to realize the limitation of the two movable magnet plates 8, without the need to set limiting components between multiple magnet pairs 7, thereby simplifying the operation and avoiding too many limiting posts 9 that need to be pressed when rotating the movable magnet plate 8.

[0038] It should be noted that the height and outer diameter of the support cylinder 11 should be considered so that the edge of the limiting groove 802 does not interfere with the support cylinder 11 when the movable magnet plate 8 rotates. Figure 2 Taking the section B-B in it as the section, when the movable magnet plate 8 rotates, the rotation trajectory of the limiting groove 802 is a circle centered on the axis of the rotating shaft 801 and with a radius of the straight line from the axis of the rotating shaft 801 to the limiting groove 802. When designing, as long as the edge of the outer diameter of the top surface of the support cylinder 11 does not interfere with the circular rotation trajectory of the limiting groove 802.
