Abstract
The utility model provides an energy -conserving air curtain machine, includes door frame, rolling slats door, air curtain machine and controlling means, the rolling slats door sets up the top of door frame, the top of door frame still is equipped with the air curtain machine, the air supply arrangement that the air curtain press packed bale draws together casing, motor, be connected with the motor and the circuit of control motor, air supply arrangement arranges in in the casing, the bottom of casing is equipped with the air outlet, controlling means includes limit switch and PLC controlling means, limit switch arranges in down the bottom of door frame, down limit switch, control motor circuit passing signal line with the PLC controlling means hookup. The utility model discloses can effectually prevent the mosquito entering, when the door is close, need not also can close the air curtain machine through artifical manual control, avoid the electric energy extravagant effectively.
Description
Technical field
The utility model relates to a kind of air curtain, particularly a kind of energy-conservation air curtain device.
Background technology
Air curtain is the airflow driving through-flow or centrifugal wind wheel to produce by high-speed electric expreess locomotive, form the door curtain that one side is invisible, utilize air curtain can blow specific region, drifting dust, such as air curtain is arranged on the passage in each workshop in factory, air curtain is just used for mosquito-proof by some workshops, and door is provided with on the passage that some install air curtain, namely, when opening the door, air curtain blowing prevents mosquito from entering, when door is shut, if do not control the closedown of air curtain manually, then air curtain is also in work, thus cause waste of energy, operationally also comparatively loaded down with trivial details.
Utility model content
The purpose of this utility model is to provide a kind of position according to rolling screen door automatically open or close air curtain, reaches mosquito-proof and the air curtain device of energy-saving effect.
To achieve these goals, the utility model have employed following technical scheme:
A kind of energy-conservation air curtain device, comprise door frame, rolling screen door, air curtain and control device, described rolling screen door is arranged on the top of described door frame, the top of described door frame is also provided with described air curtain, described air curtain comprises housing, motor, the air-supply arrangement be connected with motor and control the circuit of motor, described air-supply arrangement is placed in described housing, the bottom of described housing is provided with air outlet, described control device comprises limit switch and PLC control device, described lower position switch is placed in the bottom of described door frame, described lower position switch, the circuit controlling motor is connected with described PLC control device by holding wire.
Further, described door frame comprises two columns longitudinally arranged, and described lower position switch is placed in the bottom of described column.
Whether, as the further optimization of the technical solution of the utility model, described lower position switch is photoelectric sensor, close for detecting rolling screen door.
Preferably, the length of the housing of described air curtain is consistent with the distance between two columns.
The utility model is applicable to by the mosquito-proof workshop of air curtain, and by installing lower position switch in the bottom of door frame, when rolling screen door arrives the bottom of door frame, lower position switch by signal feedback to PLC, PLC output signal controls the circuit of air curtain, motor quits work, and lower position switch is not when sensing rolling screen door, signal is then delivered to PLC by this lower position switch, electric motor starting, the utility model can effectively prevent mosquito from entering, when door is shut, need not by controlling also can close air curtain manually, efficiently avoid waste of energy.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
The utility model is described in detail referring now to accompanying drawing.
With reference to accompanying drawing 1, a kind of energy-conservation air curtain device, comprise door frame, rolling screen door 2, air curtain 3 and control device, door frame comprises two columns 11 longitudinally arranged, rolling screen door 2 is arranged on the top of door frame, the top of door frame is also provided with air curtain, air curtain comprises housing 31, motor, the air-supply arrangement 32 be connected with motor and the circuit controlling motor, the length of housing 31 is consistent with the distance between two columns 11, the air curtain that such air curtain is formed can be effectively mosquito-proof, air-supply arrangement is placed in housing 31, the bottom of housing 31 is provided with air outlet, control device comprises limit switch 41 and PLC control device 42, lower position switch 41 is photoelectric sensor, monitor curtain rolling door by photoelectric sensor whether to close.
Lower position switch 41 is placed in the bottom of column 11, the circuit of lower position switch 11, control motor is connected with PLC control device 42 by holding wire, when rolling screen door arrives the bottom of door frame, lower position switch by signal feedback to PLC, PLC output signal controls the circuit of air curtain, and motor quits work, and when lower position switch does not sense rolling screen door, signal is then delivered to PLC by this lower position switch, electric motor starting.
Above the utility model embodiment, does not form the restriction to the utility model protection domain.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
