[0042] Most of the road cleaning equipment on the market is to fix the cleaning part around the roller. Such equipment will have the following problems in the process of use: when there are protruding parts on the ground, or the ground is uneven, due to the integrated design of the cleaning part and the roller in the existing equipment, the cleaning part cannot adjust itself on the roller, so that the cleaning will not only damage the cleaning part, but also the cleaning effect of the road cleaning equipment is not satisfactory.

[0043] In view of this, the present application provides an airport road cleaning device 100, which can solve the problem of poor uneven road cleaning effect, Figures 1 to 4 An embodiment of the airport road cleaning device 100 provided by the present application is described below in conjunction with specific drawings.

[0044] Please refer to Figures 1 to 2 An embodiment of the structure of the airport road cleaning device 100 and the cleaning roller 2 provided by the present application is shown in the figure, which includes a rack 1, the rack 1 includes a plurality of wheels 11 for driving the rack 1 to move; a cleaning roller 2, the cleaning roller 2 includes a rotating roller 21 and a cleaning part 22, the rotating roller 21 is arranged on the rack 1, and the rotating roller 21 can rotate around its own axis direction, the rotating roller 21 is provided with a limiting part 211 corresponding to the cleaning part 22, for limiting the cleaning part 22 to be partially limited in the rotating roller 21, and making the cleaning part 22 can move along the diameter direction of the rotating roller 21.

[0045] In the technical scheme of the present application, the operator can drive the frame 1 together with the entire airport pavement cleaning device 100 on the ground through the wheels 11, and the external transmission mechanism can drive the rotating roller 21 to rotate around its own axis, thereby forcing the cleaning part 22 installed on the rotating roller 21 to rotate with the rotating roller 21, driving and throwing the garbage on the ground to the designated place, thereby achieving the purpose of cleaning the garbage. In the technical scheme of the present application, by providing the limiting part 211 corresponding to the cleaning part 22 on the rotating roller 21, the cleaning part 22 can be partially limited in the rotating roller 21, and the cleaning part 22 can also be supported to move along the diameter direction of the rotating roller 21, that is, the cleaning length of the cleaning part 22 can change with the flatness of the pavement, so that the cleaning part 22 can always be in close contact with the ground during the cleaning process, improving the cleaning effect of the airport pavement cleaning device 100 on uneven pavement, thereby widening the application range of the airport pavement cleaning device 100.

[0046] In the technical scheme of the present application, the limiting part 211 includes the accommodating groove 2111 formed by the recessed side wall of the rotating roller 21, one end of the cleaning part 22 is placed in the accommodating groove 2111, and a spring 3 is arranged between the end of the cleaning part 22 and the bottom wall of the accommodating groove 2111, and a plurality of springs 3 are arranged at intervals along the extension direction of the accommodating groove 2111. In this way, the overall strength of the cleaning part 22 can be greatly improved by using the limiting relationship between the cleaning part 22 and the accommodating groove 2111, and the cleaning range of the cleaning part 22 is increased by arranging a plurality of springs 3 between the end of the cleaning part 22 and the bottom wall of the accommodating groove 2111, which utilizes the damping and extension characteristics of the spring 3, that is, the rigid collision between the cleaning part 22 and the accommodating groove 2111 is slowed down, and the cleaning range of the cleaning part 22 is increased.

[0047] Further, the cleaning part 22 includes a support strip plate 221 and a rubber strip plate 222, one end of the support strip plate 221 is recessed to form a fixing groove, for storing the rubber strip plate 222, and the other end is placed in the accommodating groove 2111; the fixing groove further includes a mounting hole 2211 penetrating the corresponding side wall of the fixing groove and a bolt 2212 penetrating the mounting hole 2211, the bolt 2212 can move along the axial direction of the mounting hole 2211, and the rubber strip plate 222 is connected with the support strip plate 221 through the bolt 2212. In this way, the support strip plate 221 is arranged between the rotating roller 21 and the rubber strip plate 222, which can effectively transmit the elastic force of the spring 3 by the rigidity of the support strip plate 221, and the cleaning range of the cleaning part 22 is increased, and the rubber strip plate 222 and the support strip plate 221 are detachably connected through the bolt 2212, so that the operator can replace the rubber strip plate 222 in time when it is excessively worn.

[0048] Further, the side wall of the fixed groove part near the notch position is inclined downward to form an avoiding groove 2213, which is used to provide a containing space for the deformation of the rubber strip 222. In this way, on the one hand, it can effectively avoid the rigid collision between the rubber strip 222 and the fixed groove part, so that the rubber strip 222 is invalid due to excessive wear. On the other hand, it can provide more activity space for the rubber strip 222, thereby increasing the cleaning range of the cleaning part 22.

[0049] Further, the rubber strip 222 includes a plurality of rubber blocks 2221 arranged along the length direction of the rubber strip 222. In this way, the rubber strip 222 can be softer and more effective to use. When facing uneven road surface, the design of the plurality of rubber blocks 2221 can greatly reduce the impact on the corresponding part of the rubber strip 222 on the flat road surface.

[0050] In the technical scheme of the present application, the rack includes a collection bin 12, and the bin opening of the collection bin 12 corresponds to the cleaning roller 2 and is used to store and arrange road surface garbage. The collection bin 12 is connected with the rack 1 through bolts. In this way, the ground garbage can be effectively collected, and the collection bin 12 and the rack 1 are detachably connected through bolts. When the collection bin 12 is full of garbage, the operator can replace it in time.

[0051] Further, the application also provides an airport pavement cleaning device 100, which comprises a rack 1, a rotating roller 21 rotatably mounted on the rack along a horizontal axis, a containing groove 2111 arranged in the radial direction of the rotating roller 21, an opposite movable plate and a supporting strip plate 221 arranged in the containing groove 2111, a spring 3 arranged between the movable plate and the bottom wall of the containing groove 2111, a first linear driving mechanism arranged between the movable plate and the supporting strip plate 221, a containing groove arranged at the end face of the supporting strip plate 221, a clamping seat arranged in the containing groove, a second linear driving mechanism arranged between the clamping seat and the bottom wall of the containing groove, and a rubber strip plate 222 clamped and arranged on the clamping seat, a plurality of conductive copper sheets arranged at the side of the rubber strip plate 222 and spaced along the length direction of the rubber strip plate 222; the airport pavement cleaning device 100 further comprises a circuit structure, a plurality of detection circuits are arranged in parallel on the circuit structure, and a plurality of conductive copper sheets are arranged on a plurality of detection circuits; in this way, by adding the first linear driving mechanism, the second linear driving mechanism and the conductive copper sheets, the staff can know the wear condition of the rubber strip plate 222 in real time according to the number of signals in the detection circuit in an open circuit state, and the length of the rubber strip plate 222 extending out of the supporting strip plate 221 is controlled by the first linear driving mechanism and the second linear driving mechanism, so that the rubber strip plate 222 has sufficient cleaning length, and the cleaning efficiency of the airport pavement cleaning device 100 is effectively ensured.

[0052] It should be noted that the first linear driving mechanism and the second linear driving mechanism are not limited, and can be electric push rods or micro cylinders.

[0053] Further, the application provides a control method of the airport pavement cleaning device 100, which refers to Figure 5 , Figure 5 which is a flowchart of the first embodiment of the control method of the airport pavement cleaning device 100.

[0054] The control method of the airport pavement cleaning device 100 comprises the following steps:

[0055] Step S10: acquiring the current open circuit signal number of the detection circuit in an open circuit state;

[0056] Step S20: determining the current wear amount of the rubber strip plate 222 according to the current open circuit signal number;

[0057] Step S30: determining the first driving parameter according to the current wear amount;

[0058] Step S40: controlling the first linear driving mechanism to move according to the first driving parameter.

[0059] In the first embodiment of the control method of the airport pavement cleaning device 100 provided by the application, the current wear amount of the rubber strip plate 222 is determined by obtaining the number of open circuit signals of the detection circuit in open circuit. The number of open circuit signals is directly proportional to the wear amount, that is, the more the number of open circuit signals, the greater the wear amount. Then, the first driving parameter is determined according to the size of the wear amount. It should be noted that the first driving parameter includes the distance value of driving the support strip plate 221 to move away from the movable plate. The first linear driving mechanism is controlled to drive the support strip plate 221 to move to the corresponding position according to the distance value. In this way, it is ensured that the rubber strip plate 222 has sufficient cleaning length, which ensures the cleaning efficiency and improves the utilization rate of the rubber strip plate 222.

[0060] Reference Figure 6 , Figure 6 The flowchart of the second embodiment of the control method of the airport pavement cleaning device 100 provided by the application is shown.

[0061] Based on the first embodiment, the plurality of conductive copper sheets includes a first limit conductive copper sheet.

[0062] The control method of the airport pavement cleaning device 100 provided by the embodiment further includes:

[0063] Step S50: When the open circuit signal of the detection circuit in which the first limit conductive copper sheet is located is obtained, the first linear driving mechanism is controlled to reset to the initial state.

[0064] Step S60: Determine the first limit wear amount of the rubber strip plate 222 according to the number of current open circuit signals.

[0065] Step S70: Determine the second driving parameter according to the first limit wear amount.

[0066] Step S80: Control the second linear driving mechanism to move according to the second driving parameter.

[0067] Step S90: After the second linear driving mechanism moves to the target state, the number of current open circuit signals is cleared, and the steps of the method of S10-S40 are re-executed.

[0068] The second embodiment of the control method of the airport pavement cleaning device 100 provided by the application needs to be explained that the specific position of the first limit conductive copper sheet is not limited, and is selected according to the length of the rubber strip 222. In this embodiment, the first limit conductive copper sheet is arranged at the middle position of the rubber strip 222. When the open circuit signal of the detection circuit where the first limit conductive copper sheet is located is obtained, it indicates that the wear amount has reached the first limit wear position. At this time, the first linear driving mechanism is controlled to return to the starting stroke position. The first limit wear amount of the rubber strip 222 is determined according to the number of current open circuit signals. The second driving parameter is determined according to the first limit wear amount. The second linear driving mechanism is controlled to move according to the second driving parameter. It needs to be explained that the second driving parameter is the distance value of driving the rubber strip 222 to move outward. The distance value is equal to the length value of the first limit wear amount, so as to ensure that the rubber strip 222 has enough cleaning length. At this time, the first linear driving mechanism is reset to the initial state, so as to avoid that the rubber strip 222 extends too long distance. After the second linear driving mechanism moves to the target state, the number of current open circuit signals is cleared, and the steps of the method of S10-S40 are executed again. In this way, the cleaning surface of the rubber strip 222 can be fully utilized, the utilization rate is improved, and the environment is saved.

[0070] Based on the second embodiment, the plurality of conductive copper sheets include a second limit conductive copper sheet.

[0071] The control method of the airport pavement cleaning device 100 of the embodiment further comprises:

[0072] Step S100: When the open circuit signal of the detection circuit where the second limit conductive copper sheet is located is obtained, update prompt information is generated.

[0073] In the third embodiment of the control method of the airport pavement cleaning device 100 provided by the application, the second limit conductive copper sheet is included in the plurality of conductive copper sheets, and the specific position of the second limit conductive copper sheet is not limited, and can be determined according to the overall length of the rubber strip 222. For example, in this embodiment, the second limit conductive copper sheet is arranged at the middle of the rubber strip 222 and close to the clamping seat. When the open circuit signal of the detection circuit in which the second limit conductive copper sheet is arranged is acquired, it indicates that the wear reaches the second limit position. At this time, the replacement prompt information is generated to prompt the replacement of the rubber strip, so as to avoid that the cleaning effect of the airport pavement cleaning device 100 is poor due to excessive wear of the rubber strip 222.
