In addition, if the wind turbine generator system is in bad weather or heavy rain, the working condition that the wind turbine generator system stops when the wind turbine generator system descends to the bottom of the tower is executed, and the wind turbine generator system tower cleaning device is disassembled and stored.
The following describes the control process or notice of four working conditions of the tower cleaning device of the wind generating set so as to better understand the technical scheme of the invention.
Executing a stop condition when the tower is lifted to the top position of the tower: before ascending, checking the UPS electric quantity and whether the cleaning liquid in the cleaning liquid filling barrel is full, and after confirming that all parts are in operation without faults, operating and maintaining personnel operate the manual control unit 5 to trigger an ascending instruction, so that the tower cleaning device of the wind generating set of the invention climbs to the top end of the tower, and the personnel should pay attention to the safe position at a distance. The wind generating set tower cleaning device is initially positioned at the bottom end of the tower, the manual control unit 5 sends an ascending instruction, the climbing mechanism 2 driving module is started, the climbing mechanism 2 driving module (the transmission motor 206) operates to drive the driving shaft of the gear 205 to rotate, so that the wind generating set tower cleaning device ascends along the outer wall of the tower, and the other climbing mechanism push rod driving module (such as the climbing mechanism push rod motor 208) is connected to push the climbing mechanism push rod 203 to extend forwards according to the change of the diameter of the tower, so that the electromagnetic chuck 201 is always kept attached to the outer wall of the tower. When the tower cleaning device of the wind generating set rises to the top end of the tower, a first position sensing unit 207 fixed at the top end of a rack 204 is triggered, a signal of the first position sensing unit 207 is automatically transmitted to a manual control unit 5, and the manual control unit 5 automatically sends out an operation stopping instruction, so that the tower cleaning device of the wind generating set stops rising.
Executing a stop condition when descending to the tower bottom position: the tower cleaning device of the wind generating set is positioned at the top end of the tower, the manual control unit 5 triggers a descending instruction, the transmission motor 206 is started to rotate, the transmission motor 206 connected with the gear 205 drives the shaft to reversely rotate, when the tower cleaning device of the wind generating set descends to the bottom position, the first position sensing unit fixed at the bottom end of the rack 204 is triggered, a signal of the first position sensing unit is automatically transmitted to the manual control unit 5, the manual control unit 5 automatically sends a stop operation instruction, and the tower cleaning device of the wind generating set stops descending.
And the working condition that the outer wall of the tower is continuously and reciprocally cleaned when the middle position is executed is as follows: after the manual control unit 5 issues the cleaning command, the descending time and the descending height of the wind turbine tower cleaning device are triggered by the second position sensor 308, and the wind turbine tower cleaning device is operated to ascend, descend or stop unless the manual control unit 5 remotely controls the signal receiver to issue the command again. The UPS on the cleaning mechanism 3 is an energy supply unit, and the second cleaning mechanism driving module is used to drive the cleaning mechanism 3 to reciprocate along the running track 1, and the triggering mode is the second position sensor 308, and the first cleaning mechanism driving module is used to drive the cleaning mechanism push rod 303, so that the rotating cleaner 304 can be guaranteed to be closely attached to the outer wall of the tower. The cleaning liquid filling barrel contains a self-defined pressurizing function to provide the rotary cleaner 304 with sufficient cleaning liquid. The signal receiver may receive a separate control of the manual control unit 5 in case of a malfunction, and may control all operating conditions of the inventive wind turbine tower cleaning device.
Executing working conditions of remotely controlling the tower to a position to be reached by the tower: although the electric power and the cleaning liquid used by the tower cleaning device of the wind generating set completely meet the actual requirements according to calculation, the working condition basically does not appear, and the situation of the working condition needs to be considered in order to prevent unexpected situations. Therefore, some UPS is best to be used, 3 to 4 sets of UPS are suitable, and the cleaning solution is required to be used in a certain margin. It should be noted that after one set of towers is cleaned, the full power UPS needs to be replaced and the cleaning solution filling barrel filled before the next set of towers is cleaned.
In summary, the cleaning device for the tower of the wind generating set has the following advantages:
the invention discloses a cleaning device for a tower of a wind generating set, which is designed for cleaning the outer part of the tower of the wind generating set with larger and larger diameter and higher tower height at present and some old wind generating sets.
