Abstract
The utility model discloses a ventilation fan air door automatic switch device in pit, including the driving motor that the driving fan air door opened and shut, post the magnetic steel sheet in this driving motor's pivot, install on the support that is close to driving motor with the hall sensor of magnetic steel sheet cooperation action, hall sensor links to each other with the PLC controller, and driving motor's positive and negative control circuit is being connected to the PLC controller, orders about driving motor through the PLC controller and carries out positive and negative rotation. The utility model discloses it is rational in infrastructure, can solve ventilation fan air door automatic switch's in the pit problem.
Description
Technical Field
The utility model relates to a ventilation fan air door automatic switch device in pit.
Background
The design of the mine underground fan and the power distribution room is far earlier, the control of a plurality of fans cannot realize the above-ground operation, and the air door is particularly the same. Due to the great promotion of the construction of the existing smart mine, the underground less humanization and unmanned property are the targets of the smart mine. The starting and stopping of the fan can be completed only by carrying out corresponding transformation and communication with the distribution room, but the opening of the air door cannot be realized in the distribution room (the air door needs to be closed for reducing resistance when the fan is started, and the air door is opened for supplying air after the starting is completed), at least more than 2 fans are far away in each mine field, the operation of the air door is only on the field, no cable or optical fiber is led to the distribution room on the field, and the cost of re-laying the cable for realizing the automatic closing of the air door is very high. Therefore, the problem of automatic opening and closing of the air door is imminent.
Disclosure of Invention
An object of the utility model is to provide a ventilation fan air door automatic switch device in pit can solve ventilation fan air door automatic switch's in pit problem.
The utility model discloses an aim at realize like this: the utility model provides a ventilation fan air door automatic switch device in pit, includes the driving motor that the driving fan air door opened and shut, pastes the magnetic steel piece in this driving motor's pivot, and the hall sensor who cooperatees the action with the magnetic steel piece is installed on the support that is close to driving motor, and hall sensor links to each other with the PLC controller, and driving motor's positive and negative control circuit is being connected to the PLC controller, orders about driving motor through the PLC controller and carries out positive and negative rotation.
The utility model discloses paste the magnetic steel piece on the main shaft of current fan to install hall sensor. The Hall device is used as a sensor of a rotating speed measuring system, and has the advantages of firm structure, small volume, light weight, long service life, convenient installation and the like. A signal wire for inducing the rotation of the main shaft by the Hall sensor is connected into a customized singlechip (STC 15W408 AS) circuit, a pulse signal is input into the singlechip to count the pulse, the pulse is compared with the pulse (the lowest rotating speed of the normal start of the fan) set in the singlechip, the fan is started when the pulse is greater than the set pulse, and the fan is closed when the pulse is less than the set pulse, so that the normally open contact switch of the relay is driven. Additionally installing a switch-on delay and switch-off delay switch, a forward and reverse rotating contactor of an air door driving motor, and the like. When the fan is started, the normally open contact of the relay is normally closed, the delay switch is switched on for timing, the delay time is set according to the operation requirement of the air door, the air door motor is driven to positively transmit the contactor after the time is up, the air door is opened (the contactor and the air door are opened for limiting interlocking, and the contactor is disconnected after being opened in place), and the automatic opening of the air door is realized. When the fan stops, the normally closed contact of the relay is normally opened, the delay closing switch is switched on for timing, the delay time is set according to the operation requirement of the air door, the air door motor is driven to close the contactor after the time is up, the air door is closed (the contactor and the air door are closed and are in limit interlocking, and the contactor is switched off after being closed in place), and the automatic air door closing is realized.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the circuit connection structure of the present invention.
Detailed Description
The utility model provides a ventilation fan air door automatic switch device in pit, as shown in figure 1, including the driving motor 6 that the driving fan air door opened and shut, it has magnet steel sheet 2 to paste in this driving motor's pivot 3, install on the support that is close to driving motor with the hall sensor 4 of magnet steel sheet cooperation action, hall sensor 4 links to each other with PLC controller 5, PLC controller 5 is connecting driving motor's positive and negative control circuit 1 that changes, positive and negative control circuit 1 is current control circuit, concrete connection structure is no longer repeated. The PLC 5 drives the driving motor 6 to rotate positively and negatively, so that the aim of automatically controlling the opening and closing of the ventilation fan air door is fulfilled.
Claims (1)
