Since the raising of temperature in base station machine room is the heat run because of electrical equipment, external environment temperature of not standing is led
It causes.As throughout the year with air-conditioning come the interior temperature that keeps standing (mainly cool down), then spring, the autumn, when the morning and evening of three season of winter and summer
Between outdoor low temperature can radiating and cooling advantage it is ignored, so as to cause the waste of electric energy, operation cost is high.
Therefore common carrier largely uses fresh air system in communication base station room, passes through in transition season outdoor cold air is direct
Base station machine room is introduced to reduce indoor temperature, to which power consumption and operation cost be greatly lowered, extend air-conditioning uses the longevity
Life.Fresh air system is discharged into indoor design scheme after all using air draught and filtering substantially, since filter device is using one section
After time, dust can excessively block strainer, cause air output deficiency and the undesirable hidden danger of running effect.Therefore fresh air system
The method that manufacturer is generally used artificial cleaning strainer, the method need to carry out frequent maintenance, and which adds the later stages
Maintenance cost and maintenance work, to bringing great inconvenience in practical application.
【Utility model content】
The purpose of this utility model is to provide for a kind of can be realized in fresh air system internal screen dust accumulation automatically more
Strainer is changed, it is easy to maintain, the fresh air system automatic filtering system of cooling-down effect is not influenced.
In order to achieve the above object, the utility model provides following technical solution：Fresh air system automatic filtering system, packet
Include rain cover, intake stack, filter device, wind turbine and electric cabinet, the rain cover is set to outside wall, the rain cover with pass through
The intake stack of wall is used cooperatively, and the filter device is set among intake stack and wind turbine, and the filter device includes
Strainer, screen support frame, the first strainer shaft, the second strainer shaft, the first filter screen shell and the second filter screen shell, the strainer
Both ends rotating around in the first strainer shaft and the second strainer shaft, the strainer is close to screen support frame and intake stack phase
Even one end, the screen support erection are placed in air inlet, and the first strainer shaft is arranged in the first filter screen shell, institute
It states the second strainer shaft to be arranged in the second filter screen shell, the first strainer shaft is driven by motor to be rotated, before the strainer
End is additionally provided with air flow sensor；The motor, wind turbine and air flow sensor and electric cabinet are electrical connected, electric cabinet timing or
Quantitatively control motor operation.
Preferably, the rain cover is " 7 " font, the lower end of the rain cover is equipped with guard.
Preferably, the strainer is one kind in non-woven fabrics, nylon wire or plastic wire.
The beneficial effects of the utility model：By the way that rain cover is arranged in exterior wall, it can prevent rainwater from entering intake stack
And the service life of filter device and wind turbine is influenced, be also prevented from the isometric bigger substance of leaf is sucked by wind turbine, can be with
The entrance for preventing the toys such as butterfly, muroid, controlling motor rotation by electric cabinet timing or quantitative mode can not tear open
In the case of unloading fresh air system, the rotation to the first strainer shaft is realized, and then realize the replacement of strainer.The utility model structure
Simply, it can realize the automatic replacement of strainer in the case where not dismantling fresh air system, improve the service life of filter device,
Post facility frequency of maintenance and maintenance cost are reduced indirectly.
【Description of the drawings】
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the operation principle block diagram of the utility model；
Marginal data：Rain cover 1, guard 11, intake stack 2, filter device 3, strainer 31, screen support frame 32, first

Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing being described in further detail to the technical solution of the utility model.
Refering to fig. 1, fresh air system automatic filtering system, including rain cover 1, intake stack 2, filter device 3,4 and of wind turbine
Electric cabinet 5, the rain cover 1 are set to outside wall, and the rain cover 1 is used cooperatively with by the intake stack 2 of wall, the mistake
Filter device 3 is set among intake stack 2 and wind turbine 4, and the filter device 3 includes strainer 31, the filter of screen support frame 32, first
Net shaft 33, the second strainer shaft 34, the first filter screen shell 35 and the second filter screen shell 36, the both ends of the strainer 31 rotating around
In the first strainer shaft 33 and the second strainer shaft 34, the strainer 31 is close to screen support frame 32 and is connected with intake stack 2
One end, the screen support frame 32 are set to 4 air inlet of wind turbine, and the first strainer shaft 33 is arranged in the first filter screen shell 35
On, the second strainer shaft 34 is arranged in the second filter screen shell 36, and the first strainer shaft 33 is driven by motor 37 revolves
