The utility model relates to a louver capable of automatically adjusting an inclination angle, which comprises a main structure of a conventional structure such as a louver frame 1, a plurality of louver blades 2 and other integral louver frames, wherein the structure is mainly used for controlling the louver blades and mainly comprises an outer shell 3, and a driving assembly, a timing control element and a blade control mechanism are arranged in the outer shell 3; the following description is divided into two parts of a driving control principle and a fan blade control mechanism:

a fan blade control mechanism:

as shown in fig. 2 of the attached drawings, the fan blade control mechanism comprises a main shaft 4 and a follow-up rod; the main shaft 4 is arranged inside the outer shell 3, and the main shaft 4 is connected with the driving assembly and drives the main shaft 4 to rotate through the driving assembly; the two ends of the main shaft 4 are provided with followers which are bearing seats 12, the bearing seats 12 are used for supporting and fixing the main shaft 4, meanwhile, the rotation of the main shaft 4 is not influenced, and the maintenance is simple and convenient.

As shown in fig. 2 of the attached drawings of the specification, a track groove 5 is formed in the surface of the main shaft 4, the follower rod is in sliding fit in the track groove 5, so as to drive the louver blades 2 to rotate, and the specific structure of the follower rod of the blade control mechanism is a rotating crank 7 and a connecting rod; one end of the rotating crank 7 is connected with the louver fan blades 2 and can rotate in a matched mode in a window frame of the louver, the other end of the rotating crank 7 is provided with a connecting shaft 8, the tail end of the connecting shaft 8 is provided with a sliding ball body 9, and the sliding ball body 9 slides in a matched mode in the track groove 5.

The unfolding view of the track groove 5 of the main shaft 4 is shown in the attached drawing fig. 3 of the specification, and can be divided into a two-stage displacement process which is divided into a high point position 13 and a low point position 14, when the main shaft 4 rotates to drive the rotating crank 7 and the sliding ball 9 to enter the high point position 13 in the track groove 5, the rotating crank 7 drives the louver blades 2 to be in a horizontal state, namely the louver blades 2 are opened, so that the indoor entering illumination amount is sufficient; when the main shaft 4 rotates to drive the rotating crank 7 and the sliding ball 9 to be at the low point 14 in the track groove 5, the louver blades 2 are in a vertical state, namely the louver blades 2 are closed, and the plurality of louver blades 2 are matched to shield indoor illumination, so that the indoor environment is in a dark environment.

However, the above solution has disadvantages, and from the viewpoint of production and processing costs and installation, the number of louver blades 2 to be installed should be set up with the corresponding track groove 5 on the main shaft 4, so that the production and processing costs are greatly increased, and therefore, in order to further save the production costs and increase the installation speed of the device, the following structure is adopted to improve:

as shown in the attached figure 2 of the specification, a transmission rod 10 is movably connected between the adjacent rotating cranks 7, and the transmission rod 10 is movably connected with the rotating cranks 7 through a short shaft 16. The track groove 5 is only required to be arranged at the rotating crank 7 at any position of the two ends of the main shaft 4, and the rotating crank 7 at any position of the two ends is connected with other rotating cranks 7 through the short shaft 16, so that the rotating crank 7 at any position of the two ends can synchronously drive other rotating cranks 7 to rotate together when sliding in the sliding groove, and further the opening and closing of the shutter blades 2 are controlled.

The driving control principle is as follows:

the driving component is a small-sized low-speed motor 11 with a brake, and can quickly stop the rotating motor, so that the precision of the inclination angle of the louver is improved, therefore, the low-speed motor 11 with low rotating speed is used as a power source, and the rotating shaft of the motor is connected with the spindle 4. The shading degree of the louver blades 2 is ensured, the light transmittance error of the louver can be further reduced by the slow rotating speed of the low-speed motor 11, the control and the rotating speed are convenient, and the voltage rotating speed can be changed from 0.83r/min to 300 r/min. When the motor rotates at an excessively high speed, the spindle 4 drives the rotating crank 7 to generate inertia shutter blades 2, so that the situation of poor shading is easily caused, and the precision is affected.

According to different growth periods of plants and different varieties of plants, the required light quantity and the required light-dark alternating frequency are different at night, so that the light-dark alternating frequency can be set for adjusting time, namely the rotating frequency of the low-speed motor 11, the timing control element controls the driving component to be opened and closed at fixed time, the control element is a timer switch, the timer switch controls the driving component to be opened and closed at fixed time, the timer switch controls the connection of a motor circuit in unit time, and the opening and closing of the low-speed motor 11 are controlled by setting the time of the required light-dark alternating frequency. For example, if the light-dark alternation frequency time period is required to be 50min each time, the set time is 25min, so that the low-speed motor 11 is driven every 25min to enter the light illumination time, and then enters the dark time after 25 min.

Because the angle of the blind greatly affects the indoor transmittance, and the deviation is probably several degrees, the precision of the device is further improved by setting a structure, and a microswitch 6 is arranged inside the outer shell 3, and the microswitch 6 controls the circuit connection of the driving component. The microswitch 6 is a switch in which an external mechanical force acts on an action reed through a transmission element to quickly connect or disconnect a fixed contact and a movable contact at the tail end of the microswitch. The micro switch 6 has a minute contact interval and a snap action mechanism, and a contact mechanism for performing a switching operation with a predetermined stroke and force is covered by a housing, and has a small external shape with a driver. As shown in the attached figure 3 of the specification, a salient point 15 is arranged on the main shaft 4, so that when the main shaft 4 rotates, the salient point contacts with a contact of the micro switch 6, the circuit of the low-speed motor 11 is controlled to be powered off, the angle of the blades 2 of the shutter is further accurately controlled, and the shading degree of the shutter is improved.

The using method is detailed as follows:

setting light and dark alternating frequency at a timer switch, wherein in an illumination period, the low-speed motor 11 is in circuit communication, the low-speed motor 11 drives the main shaft 4 to rotate, the sliding ball 9 slides from a low point position 14 to a high point position 13 in the track groove 5, and drives the rotating crank 7 and the shutter blades 2 to rotate, so that the shutter blades 2 are horizontal, and the shutter blades 2 are opened, so that the indoor space is in an illumination state; in the dark period, the low-speed motor 11 is in circuit communication, the low-speed motor 11 drives the spindle 4 to rotate, the sliding ball 9 slides from the high point position 13 to the low point position 14 in the track groove 5, the rotating crank 7 and the shutter fan blades 2 are driven to rotate, the shutter fan blades 2 are vertical, the shutter fan blades 2 are closed, and the indoor dark room state is achieved.
