The utility model discloses a double fan ventilation system, what the switching that can follow main air blower, standby fan suited carries out the automatic switch -over protection to airflow channel, has effectively avoided the loss of air output, has also avoided the fan to damage because of flowing backward the air current simultaneously.
Description
Technical field
The utility model is related to the ventilating system of the underground engineerings such as underground mining, constructing tunnel, is concretely two fans
Ventilating system.
Background technology
In the underground engineerings such as underground mining, tunnel excavation, it is required for being blown to driving face by ventilating system.By
Worked 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, sent
Connected by three-way air duct between wind air duct, once power supply or mechanical breakdown occurs in main air blower, standby fan can be opened automatically immediately
It is dynamic, it is ensured that continuous air feed.
Existing three-way air duct is in Y types or T-shaped, and containing a discharge pipe, two blast pipes, three airducts are mutually interconnected
It is logical.During work, when main air blower is blown as a example by, fraction can enter standby fan so as to cause wind loss, cause 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 into standby fan can also hinder maintenance to standby fan,
Even result in the damage of standby fan.
Utility model content
The utility model provides a kind of two fans ventilating system, can be logical to air-flow with the switching of main air blower, standby fan
Road carries out automatic switchover protection, it is to avoid wind loss and avoid blower fan from being damaged because pouring in down a chimney air-flow.
Two fans ventilating system of the present utility model, including main blast pipe and standby blast pipe, and with it is described two enter
The discharge pipe that the port of export of airduct is communicated, with main blast pipe to that should have main air blower, with standby blast pipe to that should have standby fan,
The intersection of two blast pipes outlet be provided with can by the baffle plate of axis of rotation, baffle plate can after rotation respectively with main blast pipe or
The inwall contact of standby blast pipe, baffle plate is connected to console by extending to the strut in the external world, and console passes through what is be connected
Motor and control device are connected with main air blower and standby fan respectively.After baffle plate is contacted with the inwall of corresponding blast pipe, can hinder
Trapping stream pours in down a chimney as in corresponding blower fan from the blast pipe.Because main air blower and standby fan only have one of them section at the same time
Interior startup, therefore baffle plate acquiescence is what is contacted with the inwall of standby blast pipe, after main air blower breaks down to be stopped, being started standby
During blower fan, the enabling signal of standby fan is sent in described control device simultaneously, and control device can be by PLC or single-chip microcomputer
Deng composition, its control program uses common automatic control program.Control device is opened according to the enabling signal of standby fan
Dynamic motor is rotated, and motor carries out extension and contraction control by console to strut.Rotated around the axis by the flexible drive baffle plate of strut
To being contacted with main air intake inside pipe wall, that realizes main blast pipe pours in down a chimney air-flow closing.When main air blower is enabled again, carry out on similar
The operation stated.
Further, strut is provided with sealing ring with the intersection of main blast pipe or standby blast pipe, can avoid normal blowing
When air-flow excessive leakage.
Further, the motor is either-rotation motor, convenient to control the flexible of strut, and is using an either-rotation motor
Can, it is cost-effective without using two one-way motors simultaneously.
Specifically, the worm-gear-worm in the console by coordinating is connected with strut.
Two fans ventilating system of the present utility model, can with main air blower, standby fan switching be adapted to air-flow
Passage carries out automatic switchover protection, effectively prevent the loss of air output, while it also avoid blower fan being damaged because pouring in down a chimney air-flow.
Specific embodiment with reference to embodiments, remakes further specifically to the above of the present utility model
It is bright.But this scope for being interpreted as the above-mentioned theme of the utility model should not be only limitted to following example.It is new this practicality is not departed from
In the case of the above-mentioned technological thought of type, according to various replacements or change that ordinary skill knowledge and customary means are made,
Should be included in the range of the utility model.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model two fans ventilating system.
Specific embodiment
Two fans ventilating system of the present utility model as shown in Figure 1, including main blast pipe 1 and standby blast pipe 2, Yi Jiyu
The discharge pipe 3 that the port of export of described two blast pipes is communicated.1 pair should have main air blower 6 with main blast pipe, with standby blast pipe 2 pairs
There should be standby fan 7.Being provided with the intersection of two outlets of blast pipe 1 be able to can turned by the baffle plate 4 of axis of rotation, baffle plate 4
Inwall after dynamic respectively with main blast pipe 1 or standby blast pipe 2 is contacted.Baffle plate 4 is connected to by extending to the strut 10 in the external world
Console 9, and strut 10 is provided with sealing ring with the intersection of main blast pipe 1 or standby blast pipe 2.By matching somebody with somebody in console 9
The worm-gear-worm structure control strut 10 of conjunction stretches.The control that console 9 passes through the motor 5 and single chip computer architecture being connected is filled
Put 8 to be connected with main air blower 6 and standby fan 7 respectively, wherein motor 5 is either-rotation motor.
The acquiescence of baffle plate 4 is what is contacted with the inwall of standby blast pipe 2, after main air blower 6 breaks down to be stopped, being started standby
During blower fan 7, the enabling signal of standby fan 7 is sent in the control device 8 of the single chip computer architecture simultaneously, wherein single-chip microcomputer
Control program uses 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 console 9 to strut 10.Rotated around the axis by the flexible drive baffle plate 4 of strut 10
To being contacted with the inwall of main blast pipe 1, that realizes main blast pipe 1 pours in down a chimney air-flow closing.When main air blower 6 is enabled again, class is carried out
Like above-mentioned operation.
