Description
Technical field
The utility model relates to a kind of blower fan apparatus, relate in particular to a kind of under DC low-voltage condition, can identify temperature and humidity and can be automatically or the blower fan of telecontrol.
Background technique
At present, known large wind-force blower fan adopts Ac more and carries out work by gate-controlled switch, and for there is no household electricity, and the need of work such as unattended equipment room, Switching Station reduces the operational site of temperature or humidity impracticable.DC fan can carry out work in solar powered environment, coordinates temperature and humidity sensing controller can reach automatically or the function of telecontrol.And existing minority DC fan relative size wind-force is less, the angle of blade and air-flow or blade pitgh are generally all non-adjustable, can not meet the work object of ventilation in Switching Station, ring main unit, cooling, dehumidifier, and can not automatically control according to the temperature and humidity in cabinet.
Model utility content
Provide a kind of controlled blower fan in order to overcome above-mentioned the deficiencies in the prior art the utility model, can identify showing temperature and humidity can carry out automatically or telecontrol simultaneously, and change that the blade of traditional DC fan and the angle of air-flow or blade pitgh can not be adjusted to can manual tune, can not only under low-voltage direct condition, work, can lead to manual tune simultaneously, the angle turning down and increase movable vane adapts to the variation of air quantity, blast, it regulates efficiency high, blower fan is worked in high efficiency region, reach the electricity consumption large ventilation that reduces.
The utility model solves the technological scheme that its technical problem adopts:
DC low-voltage intelligent temperature and humidity control blower fan, it is characterized in that comprising sensor, controller, direct current axial fan, power power supply unit composition, controller, direct current axial fan and power power supply unit current loop in series, sensor wiring terminal is connected on controller sensing control wiring terminal.
Described direct current axial fan adopts impeller angle adjustable structure, flow blower casing connects motor and impeller, impeller one side is fixed on flow blower casing, opposite side is according to the adjusting track of impeller, track groove is set on flow blower casing, when adjusting, adopt bolton, angle of regulation range is between 10-40 degree.
Described sensor is Temperature-Humidity Sensor.
Described controller is with RS485 remote communication interface.
The beneficial effects of the utility model are, can under the direct current condition of solar energy supply, carry out work, regulate by movable vane that to realize wind-force large, electricity consumption is little, realize left unguarded according to automatic control and the telecontrol of ambient temperature and humidity simultaneously, equipment volume is little, conveniently in Switching Station and ring main unit, installs.

embodiment:
embodiment 1:
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in Figure 1 and Figure 2, DC low-voltage intelligent temperature and humidity control blower fan, comprise that sensor 1, controller 2, power power supply unit 3, direct current axial fan 4 form, controller 2, direct current axial fan 4 and power power supply unit 3 current loop in series, sensor 1 wiring terminal is connected on controller 2 sensing control wiring terminals.
Direct current axial fan 4 adopts impeller 5 angle adjustable structures, flow blower casing 7 connects motor 6 and impeller 5, impeller 5 one sides are screwed on flow blower casing 7, opposite side is according to the adjusting track of impeller 5, track groove is set on flow blower casing 7, when adjusting, adopt bolton, angle of regulation range is between 10-40 degree.
Sensor 1 adopts polymer inlet temperature and humidity sensor, be made in conjunction with stable analog circut and switch power technology, temperature and humidity sensor controller 10 adopts the actuating of relay, controller digital display screen 9 shows temperature and humidity value in nixie tube mode, have blower fan, sensor fault instruction, change to send function, can supply remote monitoring with RS485 communication interface, user is very clear and can pass through programming button 11 initialization system parameter voluntarily.This equipment integrates measurement, demonstration, control, cooling dehumidifier and communication, and precision is high, measuring range is wide, and energy long-term work is in the rugged environment such as strong-electromagnetic field.Fan shroud 8 is in blower fan outermost, to blower fan until protective action.
When work, sensor 1 detects temperature and humidity information in Switching Station or ring main unit, and be delivered to controller 2 by controller 2 analysing and processing: in the time that the temperature in cabinet, humidity meet or exceed predefined value, relay contact closure in controller 2, direct current axial fan 4 switches on power and starts working, to carrying out air blast dehumidifier in cabinet; After a period of time, temperature in the cabinet or humidity are away from setting value, and the relay contact in controller 2 disconnects, and air blast stops.
Direct current axial fan working principle:
As Fig. 3, after fan motor 12 switches on power, impeller 5 carries out High Rotation Speed, gas axially enters impeller 5 from intake grill, be subject to impeller 5 pushing of upper blade and make gas energy raise, then flow into diffuser 13, deflection air-flow is become axial flow by diffuser 13, gas is imported to diffuser pipe simultaneously, further gas kinetic energy is converted to pressure energy, finally introduce working line.The setting angle of blade is set according to working environment, and can changes by manual tune, turn down and the angle that increases movable vane adapts to the variation of air quantity, blast, it regulates efficiency high, and can make direct current axial fan 4 work in high efficiency region.
