Abstract
The utility model discloses a baffle plate door device for a gas turbine air intake channel. The baffle plate door device comprises a baffle plate door body, wherein a control device is arranged on the baffle plate door body; the control device comprises an electric executor which is installed at the end of a baffle plate door shaft, and a limiting switch and a controller which are installed on the baffle plate door shaft; the output end of the limiting switch is connected with the input end of the controller; and the output end of the controller is connected with the electric executor. When a baffle door is opened or closed, the limiting switch acts on, an action control signal is transmitted from the contact of the limiting switch, the information about opening or closing is displayed on a display screen, a signal is transmitted to the electric executor through the controller, and the baffle plate door is opened or locked through the electric executor, so that injury accidents that a gas turbine and personnel are injured because of false action are prevented, and therefore, the security of the baffle plate door device is improved.
Description
Technical field
The utility model relates to a kind of baffle door, particularly is arranged on the baffle door on combustion machine intake duct.
Background technique
Baffle door is positioned at the intake duct of combustion machine gas handling system; thereby the baffle door device is mainly used in avoiding humid air at sealing gas handling system protection combustion machine in combustion machine shutdown situation when stopping transport to be invaded and harassed, and guarantees the effect of using dry air to purge in combustion machine compressor inlet zone.The unlatching of traditional baffle door is many by manual control, and easily because misoperation causes injury accident to combustion machine and personnel, safety in utilization is relatively poor.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of baffle door device for combustion machine intake duct, and this baffle door can be monitored baffle door, avoids occurring misoperation, thereby has improved the Security of combustion machine.
In order to solve the problems of the technologies described above, a kind of baffle door device for combustion machine intake duct of the utility model, comprise the baffle door body, described baffle door body is provided with control gear, described control gear comprises the electric actuator that is arranged on the baffle door axle head, is arranged on limit switch, controller on the baffle plate door-hinge, the output terminal of described limit switch is connected with the input end of described controller, and the output terminal of described controller is connected with described electric actuator.
Above-mentioned a kind of baffle door device for combustion machine intake duct, wherein, described controller is single-chip microcomputer.
Above-mentioned a kind of baffle door device for combustion machine intake duct, wherein, the output terminal of described controller is connected to display screen.
The beneficial effects of the utility model:
When baffle door is opened or is closed, limit switch can move, the action control signal can be sent in the contact of limit switch, in the information that shows the screen display "on" and "off", and by controller generation signal to electric actuator, by electric actuator, baffle door is opened or locked, prevent misoperation and cause injury accident to combustion machine and personnel, thereby having improved Security of the present utility model.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural drawing of control gear in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of baffle door device for combustion machine intake duct of the utility model, comprise baffle door body 1, described baffle door body 1 is provided with control gear 2, described control gear 2 comprises the electric actuator 21 that is arranged on the baffle door axle head, is arranged on limit switch 22, controller 23 on the baffle plate door-hinge, and the output terminal of described limit switch 22 is connected with the input end of described controller 23, and the output terminal of described controller 23 is connected with described electric actuator 21.Electric actuator 21 is a kind of angle rotary control gear, is mainly here the opening and closing action of carrying out baffle door, and it is installed on the axle head of baffle door, and it moves by program control.Described controller 23 is single-chip microcomputer.The output terminal of described controller 23 is connected to display screen 24, and display screen 24 can be arranged on baffle door.Limit switch quantity is unrestricted, can design according to specific requirement, can be 3.
Baffle door is opened (dotted line position in Fig. 1) or when closing, limit switch can move, the action control signal can be sent in the contact of limit switch, in the information that shows the screen display "on" and "off", and by controller generation signal to electric actuator, by electric actuator, baffle door is opened or locked, prevent misoperation and cause injury accident to combustion machine and personnel, thereby having improved Security of the present utility model.
Above embodiment's description is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
