Abstract
The invention discloses a kind of pneumatic switch and using the method for a pneumatic switch protection fans load, the wherein described pneumatic switch includes shell and switch module, the shell is equipped with mounting hole, strainer mounting hole is equipped at the air intake of shell for installing strainer, switch module includes the sense wind piece hinged by axis pin of housing central section position upper end air inlet side setting, feel the mounting bracket with shell vertical axis tilt adjustable of the shell upper end setting on the inside of wind piece, it is disposed in mounting bracket close to switch, pass through the control circuit of signal wire connection load close to switch.The beneficial effects of the invention are as follows：Easy for installation, high sensitivity and adjustable can meet sea, desert, be applied in the complex environments such as mine and cheap, stability is good.
Description
Technical field
The present invention relates to electrical equipment technical fields, more particularly to a kind of pneumatic switch.
Background technology
Have pressure switch currently on the market, incuded by pressure size, has prodigious limitation to use environment.In sand
It is used in desert, dust is excessive, is easy to block；After not working for a long time or use 1 year or more, the frequent failure of pressure switch；In sea
It is used on the harbour of side, pressure switch malfunction is often generated since seashore air quantity is excessive；Dry type is supported on installation pressure switch
It is very not convenient, can be only installed at wind turbine outlet air position or resistance region, if wind turbine because failure stop, internal temperature energy
Reach 500 DEG C, it is easy to pressure switch be caused to be damaged；Pressure switch is expensive simultaneously.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, it easy for installation, high sensitivity pneumatic is opened the present invention provides a kind of
It closes.
The technical solution adopted in the present invention is：A kind of pneumatic switch, including shell and switch module, on the shell
Strainer mounting hole is equipped with equipped with mounting hole, at the air intake of shell for installing strainer, switch module includes housing central section position
Upper end air inlet side setting the sense wind piece hinged by axis pin, feel wind piece on the inside of shell upper end setting with shell vertical pivot
The mounting bracket of line tilt adjustable, in mounting bracket placement loaded close to switch close to switch by signal wire connection
Control circuit.
Preferably, the strainer is fixed by bolt and shell strainer mounting hole.
Preferably, the strainer is the wire netting of 5*5mm.
Preferably, the pneumatic switch is fixed on entirely through shell bores on fan supporter.
Preferably, the adjustable extent at the angle of inclination is 3-45 degree.
Preferably, the shell all round closure.
Compared with prior art, the beneficial effects of the invention are as follows：Easy for installation, high sensitivity and adjustable can meet in sea
On, desert is applied in the complex environments such as mine and cheap, and stability is good.
Using the method for a pneumatic switch protection fans load, which is characterized in that wherein the method includes：
(a) method that a monitoring wind turbine starts；With
The close switch that (1) the one sense wind piece for being articulated in an axis pin is placed in close to one in a mounting bracket,
Described in axis pin be connected to a shell of the pneumatic switch, wherein described；
(2) coherent signal being had been started up close to one determination wind turbine of switch transmission is to load；
(b) method that a monitoring wind turbine stops；
(1) the sense wind piece is far from the close switch；And
(2) described to send the coherent signal of a determination wind turbine stopping to load close to switch.
Description of the drawings
Fig. 1 is the structure chart of the present invention；
Fig. 2 is air inlet direction of the present invention view；
Fig. 3 is the A-A direction views of Fig. 2 of the present invention.
In figure：1. shell, 2. mounting holes, 3. strainer mounting holes, 4. strainers, 5. close to switch, and 6. axis pins, 7. feel wind pieces,
8. mounting bracket, 9. signal wires.
Specific implementation mode
In order to be more clearly understood that technical scheme of the present invention, the following further describes the present invention with reference to the drawings.
A kind of pneumatic switch as shown in Figure 1, Figure 2, Figure 3 shows, including shell 1 and switch module, 1 surrounding of shell envelope
It closes, prevents wind direction by the sea unstable, sense wind piece is blown and allows pneumatic incorrect switching；Shell 1 is equipped with mounting hole 2,
It is the wire netting of 5*5mm that strainer mounting hole 3 is equipped at the air intake of shell 1 for installing strainer 4, the strainer, can be hindered
Keep off all be more than 5*5 sundries, tiny sundries can directly from wind turbine weight directly through, to load have no effect, switch
Component includes the sense wind piece 7 hinged by axis pin 6 of 1 medium position upper end air inlet side of shell setting, 7 inside of sense wind piece
The mounting bracket 8 with shell vertical axis tilt adjustable of 1 upper end of shell setting, the adjustable extent at the angle of inclination are
3-45 degree, the sensitivity that the difference of angle then switchs is different, and the close switch 5 of placement in mounting bracket 8 passes through signal close to switch
The control circuit of the connection load of line 9, the pneumatic switch are fixed on entirely through shell bores on fan supporter.
When dry type load wind turbine starts, flabellum rotation will generate suction, suction to it is certain when sense wind sector-meeting act,
To close close to switching.When sense wind piece is against close to switch, close switch is closed, sends a signal to load, determine wind turbine
Start, load can load；On the contrary, when load stops or wind turbine breaks down stoppings, the suction of wind turbine is inadequate, feel wind piece because
For automatic sagging reset of conducting oneself with dignity, load is just sent a signal to close to switch, wind turbine stops, according to actual requirement, load alarm or
Person unloads, and the first pipe protection is carried out to load.
The above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application range,
The equivalent change or modification that feature and principle are done, is included within the scope of present patent application.
