Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing embodiment of the present utility model is described in detail, it will be more clear making above-mentioned and other purpose of the present utility model, Characteristics and advantages.Reference numeral identical in whole accompanying drawings is indicated identical part.Deliberately do not draw in proportion accompanying drawing, focus on illustrating purport of the present utility model.
Below in conjunction with Fig. 1 the specific embodiment of aerogenerator carbon dust collecting box pick-up unit of the present utility model is elaborated.
The aerogenerator carbon dust collecting box pick-up unit of the utility model embodiment, it comprises: aerogenerator 1, master control cabinet 2, flow switch 3, aerogenerator assistant junction box 5, carbon dust collecting box 8, screen pack 9, radial ventilation pipe 10, air outlet 11, flow switch 3 comprises baffle plate 4, baffle plate 4 stretches in the carbon dust collecting box 8, flow switch 3 connects aerogenerator assistant junction box 5, and aerogenerator assistant junction box 5 connects master control cabinet 2.
In addition, as shown in Figure 1, flow switch 3 is connected with data line by power lead and is connected aerogenerator assistant junction box 5, comprises Switching Power Supply line and signal wire 7 in the aerogenerator assistant junction box 5, and it all is connected with master control cabinet 2.In the utility model specific embodiment, comprise 24V direct supply and programmable logic controller (PLC) (PLC) in the master control cabinet 2, power lead connects the 24V direct supply of master control cabinet 2, and signal wire 7 connects the switching value interface of the WP351 module of programmable logic controller (PLC).
In the utility model specific embodiment, comprise automatic detection circuit in the master control cabinet 2, according to the duty of its corresponding autotest definition flow switch 3, thus the duty of corresponding control aerogenerator 1.In the master control cabinet 2 primary control program is compiled a corresponding autotest; and the definition flow switch signal is that the carbon dust collecting box that showed aerogenerator at 0 o'clock stops up; the master control cabinet can send stop instruction and make fan parking and send a fault-signal to Central Control Room; require the staff to march into the arena the screen pack of carbon powder of generator disposable box cleared up, the aerogenerator disorderly closedown until carbon powder of generator disposable box screen pack can start shooting after clearing up.Show that the carbon powder of generator disposable box is normal when the master control cabinet receives when signal is 1, do not affect blower fan and normally move.After the flow switch energising detection signal is sent to the master control cabinet, the master control cabinet judges by the signal that gathers whether the aerogenerator carbon dust collecting box stops up.
In the utility model specific embodiment, a kind of detection method of aerogenerator carbon dust collecting box pick-up unit also is provided, wherein, aerogenerator carbon dust collecting box pick-up unit comprises: aerogenerator 1, master control cabinet 2, flow switch 3, aerogenerator assistant junction box 5, carbon dust collecting box 8, screen pack 9, radial ventilation pipe 10, air outlet 11, flow switch 3 comprises baffle plate 4, baffle plate 4 stretches in the carbon dust collecting box 8, flow switch 3 connects aerogenerator assistant junction box 5, and aerogenerator assistant junction box 5 connects master control cabinet 2; The detection method of aerogenerator carbon dust collecting box pick-up unit comprises step: a. arranges the setting value of flow switch 3; B. adopt the air mass flow at 3 pairs of air outlet 11 places of flow switch to detect, and testing result is shown by master control cabinet 2; When the flow that c. detects when flow switch 3 was not less than setting value, carbon dust collecting box 8 was without stopping up, and initiatively cabinet 2 is controlled aerogenerators 1 normal operation; The flow that detects when flow switch 3 is during less than setting value, and carbon dust collecting box 8 stops up, and initiatively cabinet 2 control aerogenerators 1 quit work.
