Description
Technical field
The utility model belongs to technical field of wind power generation, and in particular to a kind of Megawatt fan bottom of towe cabinet door safety lock.
Background technology
Megawatt fan bottom of towe cabinet door typically adopts mechanical lock at present, needs private key to open, and key is circular emptying aperture,
Once losing or forgetting to carry key, operation maintenance personnel screwdriver or other hard boards is needed to force to turn on, this
Sample operation is highly vulnerable to breakage the shape of keyhole, can not only affect the aesthetic property of cabinet door, also can make troubles to finishing operations, seriously
Meeting destroy cabinet door keyhole so that cabinet door cannot be opened.While this lock safety coefficient that can be opened with external force easily is not yet
Height, is easily opened by stranger, causes unnecessary loss.
Utility model content
The utility model provides a kind of Megawatt fan bottom of towe cabinet door safety lock, overcomes existing machinery lock to need using specially
Opened with key, operation inconvenience, security not high the problems such as.
A kind of Megawatt fan bottom of towe cabinet door safety lock that the utility model is provided, including password typing device, blower fan
PLC, micromachine, mechanical lock mechanism, man-machine interface, SCADA system, blower fan alarm lamp, the password typing device pass through I/O
Module is connected with blower fan PLC, and the micromachine input is connected with I/O module, output end and mechanical lock mechanism connect, described
Man-machine interface and SCADA system are connected with blower fan PLC respectively, and the blower fan alarm lamp is connected with SCADA system.
Further, the mechanical lock mechanism includes to cooperate travelling gear, meshing gear, dead bolt, the transmission
Gear is fixedly connected with the motor shaft of micromachine.
The beneficial effects of the utility model：Electronic lock is combined with encryption apparatus, is verified by key feeding cipher and opens
Door lock, has prevented various inconvenience and the hidden danger that brings using the mechanical lock of private key.Break down when password typing device or
During person's unpowered, opening door lock can also be gone by special-purpose machinery key, more insure reliable.The PLC carried using blower fan is done
Logic control, it is possible to achieve the faster logic judgment of password, maximized make use of blower fan resource, eliminate ordinary electronic lock institute
The chip of needs, has saved cost.Realize reporting to the police in bottom of towe man-machine interface and SCADA system, facilitate Field Force to pacify blower fan
The monitoring of full property, more safe and reliable, tool has been widely used and wide market prospects.
Description of the drawings
Fig. 1 is the utility model safety lock theory diagram.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model, it is impossible to the restriction being interpreted as to the concrete protection domain of the utility model.
Embodiment one
With reference to Fig. 1, a kind of Megawatt fan bottom of towe cabinet door safety lock, including password typing device, blower fan PLC, micro-
Type motor, mechanical lock mechanism, man-machine interface, SCADA system, blower fan alarm lamp, the password typing device by I/O module with
Blower fan PLC connects, and the micromachine input is connected with I/O module, output end and mechanical lock mechanism connect, the man-machine boundary
Face and SCADA system are connected with blower fan PLC respectively, and the blower fan alarm lamp is connected with SCADA system.The mechanical lock mechanism bag
Include cooperate travelling gear, meshing gear, dead bolt, the travelling gear is fixedly connected with the motor shaft of micromachine.Institute
State mechanical lock mechanism can also password typing device break down or unpowered in the case of, opened by mechanical key.
Workflow is as follows：Operation maintenance personnel cabinet door password key in device input cipher, I/O module by signals collecting simultaneously
Transmission fan PLC, blower fan PLC make logic judgment by the program that writes in advance, if password is correct, blower fan PLC passes through
I/O module output signal makes micromachine energising start rotation, drives mechanical lock mechanism, and the travelling gear of the mechanical lock mechanism is solid
It is mounted on motor shaft, meshing gear is engaged with travelling gear, drives meshing gear to rotate and drive dead bolt by travelling gear, make
Dead bolt is moved to left and right along motor shaft, just can achieve the purpose that unlocks, shut.
If electronic cipher input error more than three times, blower fan PLC could be made that logic judgment, touch in bottom of towe cabinet man-machine interface
" bottom of towe cabinet door prohibits warning " DTC is sent out, man-machine interface alarm lamp becomes red.Meanwhile, Central Control Room SCADA system also will collection
To alarm failure code, blower fan alarm lamp becomes red, realizes remote alarms, reminds operation maintenance personnel to take measures.
