Description

Automatic opening and closing window for barn

The utility model relates to the on/off window on a kind of warehouse of storing up grain.

At present, the on/off window in the warehouse of storing up grain generally all is manual the unlatching, when the rainfall of outside, needs window is closed, and prevents that grain from making moist, and when outside weather eyeball is good, then window should be opened, and logical light ventilates.Because manual opening and closing windows effort is time-consuming, labour intensity is big, especially when the unexpected variation of weather has little time to close window, can cause the loss that has grain in reserve in the silo, so people press for a kind of silo automatic open and close window at present.

The purpose of this utility model is exactly in order to address this problem, and a kind of silo automatic open and close window is provided.

Technical solution of the present utility model as shown in the figure.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is power supply reason figure of the present utility model.

Such as Fig. 1, the utility model has four pulley A in the four jiaos of horizontal settings in upper end of silo interior wall, B, C, D, be wound with a ring shape steel wire rope 1 above them, annular wire rope 1 is take motor 2 as power, by motor 2 just, A can be smoothly taken turns in counter-rotating, B, C, D is just doing, oppositely mobile, directly over the body of wall inwall of each window of silo, be equipped with the interior angle pulley 3 of a horizontal setting, correspondingly directly over each window, be equipped with the outer angle pulley 4 of a positioned vertical outside the body of wall under the eaves, in a couple on each window, angle pulley 3, all be wound with a backguy 5 on 4, one end of each backguy 5 and the correspondence position of annular wire rope 1 are affixed, affixed in the middle of the bottom of window 6 outer surfaces of the other end and each automatic window, be provided with the spacing change-over switch FXK of stroke above the silo interior wall, the correspondence position of the backguy of FXK and annular wire rope 1 is affixed. Electronic The control circuit of machine 2 such as Fig. 2, this circuit is made up of electronic control section and automatic control section, and electronic control section is often opened button ZA, FA and A.C. contactor C by forward, reverse starting₁、C ₂Form, forward starts often opens button ZA and A.C. contactor C₁And A.C. contactor C₂Normally-closed contact C_2－1Serial connection, reverse starting is often opened button F A and A.C. contactor C₂And A.C. contactor C₁Normally-closed contact C_1－1Serial connection, these two branch roads also connect a together termination power phase line, and the other end connects zero-power line, A.C. contactor C by the spacing change-over switch FXK of stroke and normally closed button TA₁Normally opened contact C_1－2And relay J₂Normally opened contact J_2－1All be attempted by forward and start the two ends of often opening button ZA, A.C. contactor C₂Normally opened contact C_2－2And relay J₁Normally opened contact J_1－1All be attempted by reverse starting and often open the two ends of button F A. Motor 2 is by cross-coupled A.C. contactor C₁And C₂Normally opened contact C_1－3、C _1－4、C _1－5, and C_2－3、C _2－4、C _2－5Be connected with power supply triple line X, Y, Z. Automatically control section is made up of wet control and light-operated circuit, and their power supply is by transformer B, bridge rectifier block D, integrated package of pressure-stabilizing DW and capacitor C₁′、C ₂' the direct current regulation circuit that forms provides, and this mu balanced circuit elementary is connected between the phase line and its zero line of power supply. Wet control circuit is by moisture probe L, compositing amplification tube BG₁、BG ₂And relay J₁Form, light-operated circuit is by photosensitive tube BG₅, compositing amplification tube BG₃、BG ₄And relay J₂Form, the power end of wet control circuit directly is connected with the output of direct current regulation circuit, and the power end of light-operated circuit passes through relay J₁Normally-closed contact J_1－2Be connected with the output of direct current regulation circuit. Moisture probe L and the photosensitive tube BG of automatic control section₅All be placed on the roof of silo outside or outside the eaves.

The course of work of the present utility model is as follows, and state shown in Figure 2 is the spacing change-over switch FXK of stroke and connect to starting the loop, shows that granary window is opened, waits to close, and this moment, window was opened indicator lamp L₂Bright. When pressing reverse starting and often open button F A, A.C. contactor C₂Adhesive, its normally opened contact C_2－2Closed, make the FA self-insurance, motor 2 drives annular wire rope 1 backward rotation, backguy 5 on each window 6 that then originally was tightened up is come up, and each window 6 is slowly closed downwards by own wt, when each window 6 is closed fully, the backguy that is fixed on the spacing change-over switch FXK of stroke on the steel wire rope 1 is pulled, the movable contact of FXK is transformed into forward by the reverse starting loop and starts in the loop (getting ready for windowing next time), the reverse starting loop so and dead electricity, C₂Discharge, motor 2 stalls, window is opened indicator lamp L₂Go out, window is closed indicator lamp L₁Bright. At this moment, start when often opening button ZA A.C. contactor C if press forward₁The adhesive self-insurance, motor 2 drives steel wire rope 1 forward and rotates, steel wire rope 1 drives the backguy 5 of each window, each window 6 is slowly pulled open, when each window 6 was fully withdrawn, the backguy that is fixed on the spacing change-over switch FXK of stroke on the steel wire rope 1 was pulled again, and the movable contact of FXK starts the loop by forward and is switched to again (for the next window that closes is got ready) in the reverse starting loop, therefore forward starts the loop and dead electricity, A.C. contactor C₁Discharge, motor 2 stalls, this moment, window was closed indicator lamp L₁Go out, and L₂Bright, the expression window is opened. When weather rains suddenly or silo administrator night's rest when raining, moisture probe L meets the water conducting, makes compositing amplification tube BG₁、BG ₂Conducting, then relay J₁Get electric adhesive, so it is attempted by the normally opened contact J that reverse starting is often opened button F A two ends_1－1Connect, if this moment, window 6 was opened, it will be closed immediately so, at J₁During adhesive, it is serially connected in the normally-closed contact J in the light-operated circuit_1－2Disconnect, the output of light-operated circuit and D.C. regulated power supply is disconnected, so it quits work. J_1－2Adding be in order to prevent lightning or to still have sunray when rainy and the light-operated circuit misoperation that causes. When rain excessively sunny The time, the moisture content on the humidity control head L is evaporated, not conducting of L, BG₁、BG ₂Also not conducting, J₁Dead electricity and discharge J₁Normally-closed contact J_1－2Conducting makes the light-operated circuit power connection, photosensitive tube BG₅Be subjected to the illumination conducting, compositing amplification tube BG₃、BG ₄Also conducting, then relay J₂Get electric adhesive, it is attempted by the forward startup and often opens the normally opened contact J at button ZA two ends_2－1Connect, each window 6 is opened immediately, finish light-operated function of windowing.

The utility model opens and closes the window of silo and has realized automation, need not the administrator one by one window go to open and close, significantly reduced labour intensity, especially when the unexpected variation of weather was rained, the utility model can be closed each window automatically, and the grain that the energy wall is exempted from the silo incurs loss, have easy for operation, time saving and energy saving, automaticity height, advantages such as dependable performance.
