Description
Technical field:
The utility model relates to fan technology field, more specifically to a kind of fan preventing frost for plant.
Background technique:
Frost is in mean daily temperature more than 0 DEG C, and temperature drops at short notice to be enough to crop is injured or the diastrous weather of death; Especially the impact of Late frost is more outstanding.Late frost appears at 3 annual ~ April, and now, crop starts to germinate, and serious frost causes dropping in production over a large area as crops such as tealeaves, and agriculture harvest is inflicted heavy losses on.
Frost protection fan is the temperature inversion according to weather, by the cryosphere of the heat zone air on upper strata below the effect of passing through fan flows to, crop growth environment temperature is raised, effectively reduces frost calamity and occur.
The existing fan for frost protection adopts the high-speed high-power axial-flow blower of diameter 900mm, rotating speed 950rpm, power 3.0Kw, sweeps wind for raising active area adopts to shake the head.This fan energy consumption is large, and noise is high, and because rotating speed is high, Security is low.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of plant frost prevention to freeze fan, and its noise is little, runs balance, and Safety performance is better, and structure is simple, and intelligence degree is high.
Technology solution of the present utility model is as follows:
A kind of plant frost prevention freezes fan, comprise column, the lower end of column is embedded in underground, the upper end of column is fixedly fixed with supporting plate, reducing motor is fixed on supporting frame, supporting frame is bolted on supporting plate, and the rotating shaft of reducing motor is fixed with central turnplate, and fan blade is fixed on central turnplate;
Lower temperature transducer is fixed on the bottom of column, on the top that upper temperature transducer is fixed on column or supporting frame, the temperature signal of lower temperature transducer and upper temperature transducer flows to the motor control chip of reducing motor, and motor control chip controls reducing motor work according to the temperature signal of lower temperature transducer and upper temperature transducer.
The rotation diameter of described fan blade and central turnplate is 4 ~ 8 meters, and the number of fan blade 7 is 3 ~ 8.
Height between described fan blade and ground is 4 ~ 10 meters.
The beneficial effects of the utility model are:
Its noise is little, runs balance, and Safety performance is better, and structure is simple, and intelligence degree is high.
Accompanying drawing illustrates:

Fig. 2 is the plan view of Fig. 1.
In figure: 1, column; 2, ground; 3, supporting plate; 4, supporting frame; 5, reducing motor; 6, central turnplate; 7, fan blade; 8, lower temperature transducer; 9, upper temperature transducer.
Embodiment:
Embodiment: see shown in Fig. 1,2, a kind of plant frost prevention freezes fan, comprise column 1, the lower end of column 1 is embedded under ground 2, the upper end of column 1 is fixedly fixed with supporting plate 3, and reducing motor 5 is fixed on supporting frame 4, and supporting frame 4 is bolted on supporting plate 3, the rotating shaft of reducing motor 5 is fixed with central turnplate 6, fan blade 7 is fixed on central turnplate 6;
Lower temperature transducer 8 is fixed on the bottom of column 1, on the top that upper temperature transducer 9 is fixed on column 1 or supporting frame 4, the temperature signal of lower temperature transducer 8 and upper temperature transducer 9 flows to the motor control chip of reducing motor 5, and motor control chip works according to the temperature signal control reducing motor 5 of lower temperature transducer 8 and upper temperature transducer 9.
The rotation diameter D of described fan blade 7 and central turnplate 6 is 4 ~ 8 meters, and the number of fan blade 7 is 3 ~ 8.
Height H between described fan blade 7 and ground 2 is 4 ~ 10 meters.
Working principle: the utility model, for the shortcoming of said fans, has carried out Promethean improvement.The utility model adopts 1.5Kw motor, and rotating speed is that the pole of 40 ~ 70rpm slowly runs, and almost can't hear the sound of fan running, reaches 1200m by effect plant area
2above.Be a low energy, the plant frost prevention of safe low noise freezes fan
The utility model motor control chip adopts single-chip microcomputer, Automatic control of single chip microcomputer reducing motor 5 operates, instantly temperature≤3 DEG C that detect of temperature transducer 8, when going up the temperature that temperature transducer 8 under the temperature > that temperature transducer 9 detects detects, fan is opened automatically simultaneously; When the temperature that on the temperature > that detects of temperature transducer 8, temperature transducer 9 detects instantly or the temperature > 3 DEG C that lower temperature transducer 8 detects, fan does not operate.
