[0050] Referring to the embodiments described in detail below with reference to the accompanying drawings, the advantages and features of the present utility model and the methods for realizing them will become apparent. However, the present utility model is not limited to the embodiments disclosed below, but can be implemented in various different forms. The provision of this embodiment is only to complete the disclosure of the present utility model and enable those skilled in the art to fully understand the scope of the present utility model, and the present utility model is only limited by the scope of the claims. The same reference numerals represent the same components throughout the specification.

[0051] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0052] As Figures 4 - 16 shown, this embodiment provides a foreign object cleaning device for an air-floating platform, including a vehicle body 1, and a foreign object detector 2, a brush cleaning mechanism 3, and a vacuum cleaner 4 that are all arranged on the vehicle body 1. The vehicle body 1 can move on the air-floating platform 100; the detection end of the foreign object detector 2 is oriented towards the air-floating platform 100, and the foreign object detector 2 is used to detect whether there is a foreign object 200 in the air holes 101 of the air-floating platform 100; the brush cleaning mechanism 3 includes a brush 31 and a cleaning driving member (not shown in the figure), and the cleaning driving member can drive the brush 31 to lift and lower, so that the brush 31 can enter and exit the air holes 101 of the air-floating platform 100. The cleaning driving member is signal-connected to the foreign object detector 2; the vacuum cleaner 4 can suck out the foreign object 200 on the surface of the air-floating platform 100, and the vacuum cleaner 4 is signal-connected to the foreign object detector 2.

[0053] It should be noted that when the foreign object detector 2 detects that there is a foreign object in one of the air holes 101 of the air-floating platform 100, at this time, the foreign object detector 2 is aligned with this air hole 101. The foreign object detector 2, the brush cleaning mechanism 3, and the vacuum cleaner 4 are arranged in sequence on the vehicle body 1. In other words, the relative positions among the foreign object detector 2, the brush cleaning mechanism 3, and the vacuum cleaner 4 are fixed, and the foreign object detector 2, the brush cleaning mechanism 3, and the vacuum cleaner 4 are located on the same straight line. Therefore, only by controlling the vehicle body 1 to move along the connection line direction between the foreign object detector 2 and the brush cleaning mechanism 3, the brush 31 can be aligned with this air hole 101 for cleaning.

[0054] The foreign object cleaning device for the air-floating platform of this embodiment can automatically detect whether the air holes 101 of the air-floating platform 100 are blocked by foreign objects through the foreign object detector 2. When the air holes 101 are blocked, it can control the vehicle body 1 to move so that the brush 31 is aligned with the blocked air hole 101, then drive the brush 31 to descend and extend into the blocked air hole 101 through the cleaning driving member, and then drive the brush 31 to rise to bring the foreign object 200 in the air hole 101 to the surface of the air-floating platform 100 through the brush 31. Finally, the foreign object 200 is sucked out by the vacuum cleaner 4, achieving the purpose of automatically detecting blockage and cleaning. Compared with the prior art, the working efficiency is high, and by regularly detecting and cleaning the air-floating platform 100, blockage of the air holes 101 can also be prevented in advance.

[0055] It should be noted that the foreign object 200 blocked in the air hole 101 generally has a certain viscosity and a small viscosity. Other foreign objects without viscosity can be washed away by the airflow passing through the air hole 101 and will not cause blockage. Therefore, when the brush 31 enters the air hole 101, the foreign object 200 will hang on the brush 31 instead of being poked by the brush 31 to the lower end of the air hole 101. When the foreign object 200 hangs on the brush 31 and the brush 31 is located in the air hole 101, the inner wall of the air hole 101 will squeeze the brush 31 through the foreign object 200, causing the bristles of the brush 31 to deform; when the brush 31 is withdrawn from the air hole 101, the extrusion force on its bristles disappears, and at this time the bristles will rebound and reset. Since the contact area between the foreign object 200 blocked in the air hole 101 and the brush 31 is very small and the viscosity of the foreign object 200 is small, the foreign object 200 can be separated from the brush 31 under the action of gravity, the elastic force of the bristles, and the suction force of the vacuum cleaner 4 and will not continue to adhere to the brush 31.

[0056] It should be further noted that the depth of the brush 31 entering the air hole 101 in this embodiment is not limited. Exemplarily, the lower end of the brush 31 can be located inside the air hole 101 or can penetrate out from the lower end of the air hole 101.

[0057] In this embodiment, the vehicle body 1 is provided with moving wheels 11, which facilitate the movement of the vehicle body 1 on the air floating platform 100.

[0058] In some other embodiments, a moving driving member (not shown in the figure) can also be provided. The moving driving member can be detachably installed on the air floating platform 100 by means of clamping or clamping, etc., so as to drive the vehicle body 1 to slide on the air floating platform 100 through the moving driving member.

[0059] Optionally, as Figure 4 shown, the foreign object detector 2, the brush cleaning mechanism 3, and the vacuum cleaner 4 are arranged in sequence along the traveling direction of the vehicle body 1. That is to say, the foreign object detector 2, the brush cleaning mechanism 3, and the vacuum cleaner 4 are arranged on the same straight line, and this straight line is parallel to the traveling direction of the vehicle body 1. When the vehicle body 1 is traveling, the air hole 101 can be detected by the foreign object detector 2 first, then the blocked air hole 101 can be cleaned by the brush cleaning mechanism 3, and finally the foreign object 200 can be sucked out by the vacuum cleaner 4, which is beneficial to reducing the moving distance of the vehicle body 1 and improving the detection and cleaning efficiency.

[0060] In some other embodiments, as Figure 5As shown in the figure, two foreign object detectors 2 can also be provided. Along the driving direction of the vehicle body 1, one foreign object detector 2 is arranged on the side of the brush cleaning mechanism 3 away from the vacuum cleaner 4, and the other foreign object detector 2 is arranged on the side of the vacuum cleaner 4 away from the brush cleaning mechanism 3. Thus, one foreign object detector 2 can be used to detect whether the air holes 101 are blocked, and after cleaning the air holes 101, the other foreign object detector 2 can be used to determine whether the foreign objects 200 have been removed. This not only ensures the cleaning effect, but also reduces the moving distance of the vehicle body 1, having the functions of energy saving and improving the detection and cleaning efficiency.

[0061] Optionally, the brush cleaning mechanism 3 further includes a rack 33 and a gear 34. The rack 33 is fixedly arranged on the brush 31, and the brush 31 is slidably arranged on the vehicle body 1 in the vertical direction; the gear 34 meshes with the rack 33, and the gear 34 is fixedly connected to the driving end of the cleaning driving member. The cleaning driving member can drive the gear 34 to rotate, the gear 34 drives the rack 33 to move up and down, and the rack 33 drives the brush 31 to move up and down. Thus, the structure is simple, easy to implement, and can improve the lifting stability of the brush 31, and the cleaning effect is better. Preferably, the cleaning driving member is a motor.

[0062] In some other embodiments, a cylinder or an electric push rod can also be used as the cleaning driving member to drive the brush 31 to move up and down, and the brush 31 is slidably arranged on the vehicle body 1 in the vertical direction, improving the lifting stability of the brush 31 and the cleaning effect is better.

[0063] Optionally, the brush 31 includes a brush rod 311 and a brush head. The brush rod 311 is connected to the cleaning driving member; the brush head includes a plurality of bristles 312, and the plurality of bristles 312 are arranged on the outer periphery of the brush rod 311. Thus, it is convenient to take out the foreign objects 200 in the air holes 101 through the bristles 312, ensuring that the foreign objects 200 can be completely removed.

[0064] Optionally, the lower end of the bristle 312 is connected to the brush rod 311, and the upper end of the bristle 312 inclines radially away from the brush rod 311 along the brush rod 311. Exemplarily, as Figure 11 shown, the included angle between the bristle 312 and the brush rod 311 is a, and 45°≤a≤60°. Thus, it can be ensured that the bristles 312 can grip the foreign objects 200, avoiding the bristles 312 from bending under the gravity of the foreign objects 200 and causing the foreign objects 200 to fall off, and the cleaning effect is better.

[0065] Exemplarily, the included angle a between the bristle 312 and the brush rod 311 can be any value between 45° and 60°, such as a can be 45°, 50°, 55° or 60°, etc.

[0066] Optionally, the vehicle body 1 includes a carriage 12, a brush cleaning mechanism 3 is arranged inside the carriage 12, and a cleaning port 121 for the brush 31 to enter and exit the carriage 12 is provided at the bottom of the carriage 12. When the brush 31 is needed, the brush 31 can extend through the cleaning port 121 to clean the blocked air holes 101; when the brush 31 is not needed, the brush 31 can be retracted into the carriage 12 through the cleaning port 121 for storage, making the foreign object cleaning device of the air floating platform more tidy and beautiful.

[0067] Further, the foreign object detector 2 can be arranged inside the carriage 12, and an avoidance port 122 is provided at the bottom of the carriage 12 opposite to the detection end of the foreign object detector 2 to ensure the normal operation of the foreign object detector 2, which is beneficial to further improve the aesthetics of the foreign object cleaning device of the air floating platform.

[0068] Further, the vacuum cleaner 4 can be arranged inside the carriage 12, and the suction port 41 of the vacuum cleaner 4 is arranged at the bottom outside the carriage 12, which is convenient for the suction port 41 to suck foreign objects 200 on the air floating platform 100, and is also beneficial to further improve the aesthetics of the foreign object cleaning device of the air floating platform.

[0069] Optionally, the outer diameter of the brush head is D, the outer diameter of the brush rod 311 is d1, and the inner diameter of the cleaning port 121 is d2, where d1 < d2 < D. When the brush 31 passes through the cleaning port 121, the bristles 312 can be squeezed by the inner wall of the cleaning port 121 and the opening end face of the cleaning port 121 to clean the brush 31 and prevent foreign objects 200 from adhering to the bristles 312.

[0070] Optionally, the inner diameter of the air hole 101 of the air floating platform 100 is d0, the outer diameter of the brush head is D, and D = d0 + x, where 5% d0 ≤ x ≤ 15% d0. This can not only ensure that the brush head can smoothly enter and exit the air hole 101, but also ensure that the brush head can take out all foreign objects 200, preventing some foreign objects 200 from remaining in the air hole 101 and affecting the cleaning effect.

[0071] Exemplarily, the outer diameter D of the brush head can be any value between d0 + 5% d0 and d0 + 15% d0. For example, D can be d0 + 5% d0, d0 + 6% d0, d0 + 7% d0, d0 + 8% d0, d0 + 9% d0, d0 + 10% d0, d0 + 11% d0, d0 + 12% d0, d0 + 13% d0, d0 + 14% d0, d0 + 15% d0, etc.

[0072] Optionally, the plurality of bristles 312 include a plurality of first bristles 3121 and a plurality of second bristles 3122, and the length of the first bristles 3121 is greater than the length of the second bristles 3122. By the cooperation of bristles 312 with different lengths, it can be ensured that foreign objects 200 can be firmly grasped by the bristles 312 and there will be no problem of foreign objects 200 falling off.

[0073] In this embodiment, the foreign object detector 2 is an infrared ranging sensor. In some other embodiments, the foreign object detector 2 can also be a photographing device such as a camera.

[0074] Let the distance value measured by the infrared ranging sensor be denoted as H, and the distance between the upper surface of the air-floating platform 100 and the infrared ranging sensor be denoted as H p .

[0075] When using the air-floating platform foreign object cleaning device to detect and clean the foreign objects on the air-floating platform 100, the vehicle body 1 moves at a constant speed on the air-floating platform 100 and detects each air hole 101 according to a preset route (such as Figure 7 the route indicated by the arrow in

[0076] As Figure 12 shown, when H = H p , it indicates that the infrared ranging sensor has not been aligned with the air hole 101, and the vehicle body 1 continues to move forward.

[0077] As Figure 13 shown, when H is greater than a predetermined value H0 (for example, the predetermined value H0 is equal to the sum of H p and the depth of the air hole 101. Of course, the predetermined value H0 can also be greater than the sum of H p and the depth of the air hole 101), it indicates that the infrared ranging sensor has been aligned with the air hole 101 and there is no foreign object 200 in this air hole 101, and the vehicle body 1 continues to move forward.

[0078] As Figure 14 shown, when H > H p , it indicates that the infrared ranging sensor has been aligned with the air hole 101 and there is a foreign object 200 in this air hole 101. Then, the vehicle body 1 is moved forward by a distance equal to the horizontal distance between the infrared ranging sensor and the brush 31 (since the horizontal distance between the infrared ranging sensor and the brush 31 is a fixed value, the control method of controlling the vehicle body 1 to move forward a fixed distance when H > H p is a prior art and will not be elaborated here), so that the brush 31 is aligned with this air hole 101. Then, the cleaning driving member is driven to drive the brush 31 to extend into this air hole 101, and the foreign object 200 is taken out to the surface of the air-floating platform 100. Then, the vehicle body 1 continues to move forward, and the foreign object 200 is sucked out by the vacuum cleaner 4. After the foreign object 200 is sucked out by the vacuum cleaner 4, the vehicle body 1 can be retracted and the foreign object detector 2 can be used to confirm whether the foreign object 200 has been removed.

[0079] As Figure 15 shown, when H < H pWhen it indicates that there is a foreign object 200 on the surface of the air-floating platform 100 or at the orifice of the air hole 101, the vehicle body 1 is moved forward by a preset distance (the preset distance is a value set in advance, for example, the preset distance is equal to the distance between two adjacent air holes 101, and the preset distance can be selected according to requirements and is not limited herein), so as to suck out the foreign object 200 through the vacuum cleaner 4, and then the control module of the vehicle body 1 is used to control the vehicle body 1 to retreat and confirm whether the foreign object 200 has been removed through the foreign object detector 2.

[0080] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be manufactured in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or basic characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all aspects and not restrictive.
