[0009] The present invention has the following beneficial effects:

[0010] This invention utilizes a cleaning component. When the outer surface of the tough cleaning plate contacts the airport floor, the weight of the dust collection box causes a sliding plate inside the cylindrical rod to move inward along with a square plate and an arc-shaped push plate due to the reaction force. The square plate's movement compresses a spring, while the arc-shaped push plate's movement compresses the water in the water tank. When the sliding plate returns to its original position under the influence of the spring, the water in the water tank enters the water guide channel under negative pressure, then flows out through the outlet via a water limiting plate, thus wetting the outer surface of the tough cleaning plate. This rolling cleaning method allows for multiple cleanings of stubborn deposits on the airport floor, significantly improving cleaning efficiency. The cleaning effect on the airport floor is achieved by using water-limiting plates to restrict the direction of water flow. Their unique tilt angle makes it extremely difficult for water to flow back into the water storage tank. Water flowing out of the storage tank, due to the tilt angle, is accelerated in speed and efficiency. As the curved push plate is pushed inward, the corresponding push rod inserts into the water channel inside. Because the push rod and the water channel have the same shape and size, the water in the storage tank flows into the water channel located elsewhere under the pushing force of the curved push plate. This ensures that each flexible cleaning plate is wetted with high efficiency, indirectly improving cleaning efficiency.

[0011] This invention utilizes a baffle, allowing workers to move the dust collection box by pushing a lever. The pushed dust collection box then moves via rollers. The baffle on its left side pushes away any debris on the ground that might obstruct the movement of the dust collection box, thus improving its mobility and reducing water stains on the airport floor, thereby enhancing the overall cleanliness. The connecting plate can also limit the position of the long lever and simultaneously restrict the movement of the rollers.

[0012] This invention uses a dust collection box to start the vacuuming device and motor. The large gear starts to rotate under the influence of the rotating rod. Relying on the meshing effect, it drives the large gears on both sides and the small gear at the bottom to rotate. The small gear drives the cylindrical rod to rotate together through a short rod. The rotating cylindrical rod cleans the airport floor through the flexible cleaning plate. Relying on the rolling cleaning component, while cleaning the dust and attached objects on the airport floor, it can also wet the flexible cleaning plate on the outside of the cleaning component, so that the cleaned dust can adhere to the flexible cleaning plate, which greatly improves the cleaning effect of the airport floor and reduces dust.

[0013] This invention utilizes a dust extraction device that uses a circular tube and a suction pipe to remove dust generated during cleaning by the cleaning components, reducing dust pollution and significantly improving the efficiency of cleaning airport floors. It also avoids the psychological impact of dust pollution on passengers. Furthermore, the invention employs a water tank that, due to the downward flow of water, replenishes the water tank when the water level in the storage tank decreases by rapidly flowing into the storage tank through a guide pipe and a delivery pipe under the influence of gravity.

The square plate 103 is fixedly connected to the left and right sides inside the dust collection box 1, and the square plate 103 has a round opening inside. The shape and size of the round opening are the same as the shape and size of the suction pipe 102. Through the suction device 2, the suction device 2 will suck up the dust raised by the cleaning component 107 during cleaning through the round tube 101 and the suction pipe 102, which reduces the occurrence of dust and greatly improves the efficiency of vacuuming and cleaning the airport floor. It also avoids the psychological impact on passengers caused by dust.

[0027] Cleaning components 107 are provided on the left and right sides inside the dust collection box 1. Small gears 106 are provided at the front and rear ends of the cleaning components 107. Large gears 105 are provided on the top of the small gears 106. A rotating rod 104 is horizontally fixedly connected inside the large gear 105.

[0028] Five large gears 105 mesh with each other, and large gears 105 and small gears 106 mesh with each other.

[0029] The large gear 105 located at the central shaft is rotatably connected to the motor 7 via the rotating rod 104, and the lower end of the outer surface of the cleaning component 107 is at the same height as the lower end of the outer surface of the roller 12.

[0031] Dust collection box 1, the dust collection box 1 is in the shape of an inverted concave shape, a dust collection device 2 is fixedly connected to the top of the dust collection box 1, a water tank 3 is fixedly connected to the back of the dust collection box 1, a straight rod 4 is fixedly connected to the right side of the dust collection box 1, and a push rod 5 is fixedly connected to the right end of the straight rod 4 laterally.

[0032] Limiting plate 6 is arc-shaped. A motor 7 is fixedly connected to the inner top surface of limiting plate 6. A baffle 8 is provided at the left end of dust collection box 1, and a support block is fixedly connected to the right side of baffle 8. Baffle 8 is connected to dust collection box 1 through support block. A long rod 11 is horizontally arranged directly below the inner surface of dust collection box 1. Rollers 12 are fixedly connected to the front and rear ends of long rod 11, and the lower end of the outer surface of roller 12 is in contact with the ground. A connecting plate is fixedly connected to the outer surface of long rod 11, and the top of the connecting plate is connected to dust collection box 1. The position of long rod 11 can be limited by the connecting plate, and the roller 12 can also be limited.

[0033] The dust collection box 1 includes a round tube 101, a suction pipe 102, and a square plate 103. The round tube 101 is located inside the dust collection box 1, and the suction pipe 102 is fixedly connected to the left and right sides of the round tube 101. The suction pipe 102 is connected to the vacuuming device 2 through the round tube 101. The square plate 103 is fixedly connected to the left and right sides inside the dust collection box 1, and the square plate 103 has a round opening inside. The shape and size of the round opening are the same as the shape and size of the suction pipe 102. By starting the vacuuming device 2 and the motor 7 through the dust collection box 1, the large gear 105 starts to rotate under the influence of the rotating rod 104, relying on the meshing effect. Simultaneously, the large gears 105 on both sides and the small gear 106 at the bottom are driven to rotate. The small gear 106 drives the cylindrical rod 71 to rotate together through the short rod. The rotating cylindrical rod 71 cleans the airport floor through the flexible cleaning plate 72. Relying on the rolling cleaning component 107, while cleaning the dust and attachments on the airport floor, the flexible cleaning plate 72 on the outside of the cleaning component 107 is also wetted, so that the cleaned dust can adhere to the flexible cleaning plate 72, which greatly improves the cleaning effect of the airport floor and reduces dust.

[0034] Cleaning components 107 are provided on the left and right sides inside the dust collection box 1. Small gears 106 are provided at the front and rear ends of the cleaning components 107. Large gears 105 are provided on the top of the small gears 106. A rotating rod 104 is horizontally fixedly connected inside the large gear 105.

[0035] Five large gears 105 mesh with each other, and large gears 105 and small gears 106 mesh with each other.

[0036] The large gear 105 located at the central shaft is rotatably connected to the motor 7 via the rotating rod 104, and the lower end of the outer surface of the cleaning component 107 is at the same height as the lower end of the outer surface of the roller 12.

[0037] Cleaning assembly 107 includes a cylindrical rod 71, a flexible cleaning plate 72, a sliding plate 73, a square plate 74, and an arc-shaped push plate 75. The flexible cleaning plate 72 is fixedly connected to the outer surface of the cylindrical rod 71. A water storage tank is horizontally arranged at the central axis of the cylindrical rod 71, and the water storage tank is cylindrical in shape. A groove is formed on the outer side of the water storage tank, and the arc-shaped push plate 75 is slidably connected to the inside of the groove. A square groove is formed on the side of the groove away from the water storage tank, and the sliding plate 73 is slidably connected to the inside of the square groove. Sliding grooves are formed on the left and right sides of the inner wall of the square groove, and the square plate 74 is slidably connected to the inside of the sliding grooves. When the outer surface of the flexible cleaning plate 72 comes into contact with the airport ground through the cleaning assembly 107, it is subjected to the gravity of the dust collection box 1. The sliding plate 73 located inside the cylindrical rod 71 is affected by the reaction force, which will drive the square plate 74 and the arc-shaped push plate 75 to move inward together. When the square plate 74 moves, it will squeeze the spring, and when the arc-shaped push plate 75 moves, it will squeeze the water in the water tank. When the sliding plate 73 returns to its original position under the influence of the spring, the water in the water tank will enter the water guide channel under the influence of the negative pressure effect, and then flow out from the outlet through the water limiting plate 76, thereby achieving the effect of wetting the outer surface of the tough cleaning plate 72. Through the rolling cleaning method, the stubborn attachments on the airport floor can be cleaned multiple times, which greatly improves the cleaning effect of the airport floor.

[0038] The top of the sliding plate 73 is fixedly connected to the inner surface of the tough cleaning plate 72, and the bottom of the sliding plate 73 is fixedly connected to the inner surface of the arc-shaped push plate 75. The cylindrical rod 71 is connected to the pinion 106 through a short rod, and the pinion 106 is rotatably connected to the dust collection box 1 through the short rod.

[0039] The square plate 74 is fixedly connected to the sliding plate 73. The shape and size of the square plate 74 are the same as those of the slide groove. A spring is fixedly connected to the bottom of the square plate 74, and the end of the spring away from the square plate 74 is connected to the inner wall of the slide groove.

[0040] The sliding plate 73 has a water guide groove inside, and a water limiting plate 76 is fixedly connected inside the water guide groove. The water limiting plate 76 is inclined. Water outlets are opened on the left and right sides inside the water guide groove. The positions of the water outlets correspond to the positions of the tough cleaning plate 72. A round rod is fixedly connected horizontally inside the water storage tank. A top rod 77 is fixedly connected to the outer surface of the round rod. Through the water limiting plate 76, the direction of water flow is restricted. Due to its special inclination angle, it is very difficult for water to flow back into the water storage tank. The water flowing out of the water storage tank will be accelerated to a certain extent due to its inclination angle.

[0041] The six push rods 77 are arranged in a hexagonal shape, and the positions of the push rods 77 correspond to the positions of the water guide channels. The shape and size of the top of the push rod 77 are the same as those of the water guide channels. When the arc-shaped push plate 75 is pushed inward, the push rod 77 at the corresponding position will be inserted into the water guide channel inside it. Since the push rod 77 has the same shape and size as the water guide channel, the water in the water storage channel will flow into the water guide channel located in other positions under the influence of the pushing force of the arc-shaped push plate 75. This allows each tough cleaning plate 72 to be wetted, and the wetting efficiency is high, which indirectly improves the cleaning efficiency.

[0042] The water tank 3 includes a water inlet 31, a water guide pipe 32, and a water delivery pipe 33. The water inlet 31 is fixedly connected to the central axis at the top of the water tank 3. The water guide pipe 32 is fixedly connected to the left and right sides at the bottom of the water tank 3. The water delivery pipe 33 is fixedly connected to the left side of the water guide pipe 32. Through the water tank 3, relying on the downward flow of water, when the water in the storage tank decreases, the water inside the water tank 3 will quickly enter the storage tank through the water guide pipe 32 and the water delivery pipe 33 under the influence of gravity, which can replenish the water lost in the storage tank.

[0043] The water supply pipe 33 extends through the back of the dust collection box 1 and to the right of the small gear 106 on the right side on the left side. The water supply pipe 33 also extends through the short rod on the left side and into the water storage tank.

[0044] The number of cylindrical rods 71, water supply pipes 33 and water guide pipes 32 are the same, and the short rod is rotatably connected to the outer surface of the water guide pipe 32.

[0045] A specific application of this embodiment is as follows: Workers can move the dust collection box 1 by pushing the push rod 5. The pushed dust collection box 1 will then move via the rollers 12. The baffle 8 on its left side can push some debris on the ground that might affect the movement of the dust collection box 1 to both sides. Before moving the dust collection box 1, the vacuuming device 2 and the motor 7 are started. The large gear 105 begins to rotate under the influence of the rotating rod 104. Through meshing, it simultaneously drives the large gears 105 on both sides and the small gear 106 at the bottom to rotate. The small gear 106 will rotate via the short rod... The cylindrical rod 71 rotates along with the dust collection box 1, and the rotating cylindrical rod 71 cleans the airport floor through the flexible cleaning plate 72. When the outer surface of the flexible cleaning plate 72 contacts the airport floor, under the weight of the dust collection box 1, the sliding plate 73 inside the cylindrical rod 71 is affected by the reaction force, which drives the square plate 74 and the arc-shaped push plate 75 to move inward together. When the square plate 74 moves, it compresses the spring, and when the arc-shaped push plate 75 moves, it compresses the water in the water tank. When the sliding plate 73 returns to its original position under the influence of the spring, the water in the water tank will be affected by the negative pressure effect. The water enters the water guide channel and then flows out of the outlet through the water limiting plate 76, thus wetting the outer surface of the tough cleaning plate 72. When the tough cleaning plate 72 contacts the ground, it will drive the sliding plate 73 to move. When it contacts the outer surface of other cylindrical rods 71, it will also be affected by the reaction force, causing the sliding plate 73 to move. The water limiting plate 76 achieves the function of restricting the direction of water flow. Relying on its special tilt angle, it makes it extremely difficult for water to flow back into the water storage tank. When the arc-shaped push plate 75 is pushed inward, the corresponding top rod 77 will insert into the water tank inside. The push rod 77 has the same shape and size as the water guide channel, so under the push of the arc-shaped push plate 75, the water in the water storage tank will flow into the water guide channel located in other positions under its thrust. Relying on the characteristic of water flowing downward, when the water in the water storage tank decreases, the water inside the water tank 3 will quickly enter the water storage tank through the water guide pipe 32 and the water supply pipe 33 under the influence of gravity, which can replenish the water lost in the water storage tank. At this time, the vacuuming device 2 will suck up the dust raised by the cleaning component 107 during cleaning through the round pipe 101 and the vacuum pipe 102, reducing the occurrence of dust.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
