Abstract
The invention relates to a dual-fan ventilation system. The dual-fan ventilation system comprises a main air inlet pipe, a standby air inlet pipe and an air outlet pipe communicated with the outlet ends of the two air inlet pipes, wherein the main air inlet pipe corresponds to a main fan, and the standby air inlet pipe corresponds to a standby fan; a baffle plate capable of rotating through a rotating shaft is arranged at the junction of outlets of the two air inlet pipes, can be in contact with the inner wall of the main air inlet pipe or the standby air inlet pipe after rotating respectively, and is connected to a console through a support rod extending to the outside; the console is connected with the main fan and the standby fan through a motor and a control device which are connected respectively. According to the dual-fan ventilation system, automatic switching protection over an airflow passage can be adaptively realized along with switching of the main and standby fans, so that loss of the air discharge volume is effectively avoided, and meanwhile, the fans are also prevented from being damaged by a backflowing airflow.
Description
Technical field
The present invention relates to the ventilating system of the underground engineering such as underground mining, constructing tunnel, it is concretely two fans ventilation
System.
Background technology
In the underground engineerings such as underground mining, tunnel excavation, it is required for blowing to driving face by ventilating system.By
Work long hours in blower fan and easily break down, therefore at present frequently with dual air blowers and dual power, its main air blower, standby fan, send
Connected by three-way air duct between wind air duct, once power supply or mechanical breakdown in main air blower, standby fan can open immediately automatically
Dynamic it is ensured that continuous air feed.
Existing three-way air duct is in Y type or T-shaped, containing a discharge pipe, two blast pipes, three airduct phase interconnection
Logical.During work, when main air blower is blown as a example, fraction can enter standby fan thus leading to wind loss, leads to reality
Air output is not enough, easily causes potential safety hazard, therefore in order to ensure air output it is necessary to increase the work(of main air blower, standby fan
Rate, considerably increases the cost of whole system；Meanwhile, the air-flow entering standby fan also can hinder the maintenance to standby fan,
Even result in the damage of standby fan.
Content of the invention
The invention provides a kind of two fans ventilating system, with the switching of main air blower, standby fan, gas channel can be entered
Row automatically switches protection, it is to avoid wind loss and avoid blower fan to damage because pouring in down a chimney air-flow.
The two fans ventilating system of the present invention, including main blast pipe and standby blast pipe, and with described two blast pipes
The discharge pipe that communicates of the port of export, with main blast pipe to there being main air blower, with standby blast pipe to there being standby fan, at two
Blast pipe outlet intersection be provided with can by the baffle plate of axis of rotation, baffle plate can after rotation respectively with main blast pipe or standby
The contact internal walls of blast pipe, baffle plate is connected to control station by extending to the strut in the external world, and control station passes through the motor being connected
It is connected with main air blower and standby fan respectively with control device.After the contact internal walls of baffle plate and corresponding blast pipe, gas can be intercepted
Stream is from this blast pipe pours in down a chimney as corresponding blower fan.Open in section at the same time because main air blower and standby fan only have one of them
Dynamic, therefore baffle plate acquiescence is and the contact internal walls of standby blast pipe, after main air blower breaks down stopping, starting standby fan
When, the enabling signal of standby fan is simultaneously sent in described control device, and control device can be by structures such as PLC or single-chip microcomputers
Become, its control program adopts common automatic control program.Control device starts electricity according to the enabling signal of standby fan
Machine rotates, and motor carries out extension and contraction control by control station to strut.By the flexible drive baffle plate of strut rotate around the axis to
Main blast pipe contact internal walls, that realizes main blast pipe pours in down a chimney air-flow closing.When enabling main air blower again, carry out similar above-mentioned
Operation.
Further, strut and the intersection of main blast pipe or standby blast pipe are provided with sealing ring, can avoid normally drying
Seasonal epidemic pathogens stream excessive leakage.
Further, described motor is either-rotation motor, conveniently controls the flexible of strut, and using an either-rotation motor is
Can, without simultaneously using two one-way motors, cost-effective.
Specifically, the worm-gear-worm passing through cooperation in described control station is connected with strut.
The two fans ventilating system of the present invention, can with main air blower, standby fan switching be adapted to gas channel
Carry out protection of automatically switching, effectively prevent the loss of air output, it also avoid blower fan simultaneously and damage because pouring in down a chimney air-flow.
Specific embodiment with reference to embodiments, is described in further detail to the above of the present invention again.
But this scope being interpreted as the above-mentioned theme of the present invention should not be only limitted to Examples below.Thinking without departing from the above-mentioned technology of the present invention
In the case of thinking, the various replacements made according to ordinary skill knowledge and customary means or change, all should include at this
In bright scope.
Brief description
Fig. 1 is the structural representation of two fans ventilating system of the present invention.
Specific embodiment
The as shown in Figure 1 two fans ventilating system of the present invention, including main blast pipe 1 and standby blast pipe 2, and with described
The discharge pipe 3 that the port of export of two blast pipes communicates.With main blast pipe 1 to should have main air blower 6, with standby blast pipe 2 to should have
Standby fan 7.It is provided with the baffle plate 4 that can pass through axis of rotation in the intersection of two blast pipe 1 outlets, baffle plate 4 can be after rotation
Contact internal walls with main blast pipe 1 or standby blast pipe 2 respectively.Baffle plate 4 is connected to control by extending to the strut 10 in the external world
Platform 9, and strut 10 is provided with sealing ring with the intersection of main blast pipe 1 or standby blast pipe 2.Pass through cooperation in control station 9
Worm-gear-worm structure control strut 10 stretches.Control station 9 passes through 8 points of the control device of the motor 5 and single chip computer architecture being connected
It is not connected with main air blower 6 and standby fan 7, wherein motor 5 is either-rotation motor.
Baffle plate 4 acquiescence is and the contact internal walls of standby blast pipe 2, after main air blower 6 breaks down stopping, starting standby
During blower fan 7, the enabling signal of standby fan 7 is simultaneously sent in the control device 8 of described single chip computer architecture, wherein single-chip microcomputer
Control program adopts common automatic control program.Control device 8 starts motor 5 according to the enabling signal of standby fan 7
Rotate, motor 5 carries out extension and contraction control by control station 9 to strut 10.Rotated around the axis by the flexible drive baffle plate 4 of strut 10
Extremely with main blast pipe 1 contact internal walls, that realizes main blast pipe 1 pours in down a chimney air-flow closing.When enabling main air blower 6 again, carry out class
Like above-mentioned operation.
