Title:
SELF-PROPELLED VACUUM DEVICE AND NOZZLE POSITION CONTROL METHOD FOR THIS DEVICE
Document Type and Number:
Japanese Patent JP2023165229
Kind Code:
A
Abstract:
To automatically control a nozzle position of a self-propelled vacuum device to more reliably suck up deposits.SOLUTION: A self-propelled vacuum device 10 is capable of rotating a vacuum nozzle 16 around a rotation shaft 24 (point A) provided on a vehicle body 12 using a power cylinder 20. A tilt angle sensor is provided to detect a tilt angle θ of the vehicle body 12. A target nozzle angle φref around the rotation shaft 24 (point A) is calculated based on the tilt angle θ and a target height yref of a tip of the nozzle 16. Rotation of the nozzle 16 around the rotation shaft 24 is feedback-controlled using the target nozzle angle φref as a target value.SELECTED DRAWING: Figure 1
