Specifically, the retraction and extension driving part comprises a retraction driving motor 28, a corner part 29, a screw rod 21 and a nut 22, wherein the driving end of the retraction driving motor 28 is connected with one end of the screw rod 21, and the nut 22 is in threaded fit with the screw rod 21; the corner piece 29 is hinged on the sealed cleaning cover 6, the upper end of the corner piece 29 is provided with a sliding groove, and a convex block is fixed on the screw nut 22 so as to be in sliding fit with the sliding groove and drive the corner piece 29 to rotate. The corner piece 29 is connected to the auxiliary wheel 16, in particular by means of a lifting bar 30.
Fig. 5 is a simple flow path of the composite multifunctional negative pressure cleaning device for cleaning a wall surface with obstacles, and the cleaning of the mechanism shown in the figure can be divided into 6 steps.
and step 2, the negative pressure cleaning device contacts the working surface after extending out to start cleaning. At this time, the negative pressure cleaning device can be adsorbed to the working surface by the negative pressure effect of the sealed cleaning cover 6, and the spray softening of the internal spray head 2 and the brush scrubbing of the rolling brush are simultaneously carried out. The front end of the negative pressure cleaning device is monitored by the ultrasonic sensor at the front end in real time to be away from the barrier so as to prepare for opening the front flip cover 4.
And step 3, when the distance between the negative pressure cleaning device and the obstacle is smaller than a set value, opening the front flip cover 4, and starting the obstacle end surface cleaning operation after the front contact probe sensor 13 contacts one end surface of the obstacle. This step will enter the end phase after the front contact probe sensor 13 has left the range of the obstacle.
And step 6, preparing to adjust and recover after the negative pressure cleaning device finishes cleaning the preset working range.
In conclusion, the composite multifunctional negative pressure cleaning device has the following advantages:
1. through the negative pressure unit 8, the cleaning unit and the rolling brush, the negative pressure suction force is adopted to combine the cleaning agent spraying and the brush cleaning operation, an effective closed environment is provided for the cleaning agent spraying and the brush cleaning operation through the sealed cleaning cover 6, the situations that the cleaning solution is excessively covered and the used cleaning solution overflows a controllable range to cause secondary pollution to a working surface can be avoided, and the dirty solution is convenient to recycle;
2. the ultrasonic sensor at the front end of the negative pressure cleaning device can detect the distance from the operation front end of the negative pressure cleaning device to the obstacle on the surface of the wall body, so that the basis of whether the negative pressure cleaning device is opened or not and when the flip covers at the front end and the back end are opened is provided for the negative pressure cleaning device, the cleaning range of the rolling brush is effectively expanded, and the negative pressure cleaning device can clean the surface of the vertical position of the obstacle in front of the operation direction.
3. The air in the sealed cleaning cover 6 is pumped out through the negative pressure fan, so that the air pressure in the cavity is obviously lower than the external atmospheric pressure, positive working pressure is provided for the negative pressure cleaning device under the action of pressure difference, and the rolling brush can be ensured to be capable of forcefully brushing the surfaces to be cleaned, such as the glass curtain, the aluminum-plastic plate and the like;
4. this compound negative pressure belt cleaning device can also switch different passing through mode according to the difference of building surface material. In addition to normal cleaning, the auxiliary wheel 16 in the negative pressure cleaning device can provide stable operation support when the surface of the building is in a particulate form or a non-scrubbing lime wall surface, so that the structure of the wall surface is protected, and the mechanical structure and the sealing equipment of the negative pressure cleaning device are protected from being scratched by the wall surface.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various improvements and modifications without departing from the technical principle of the present invention, and those improvements and modifications should be also considered as the protection scope of the present invention.
