Description

[Detailed description of the invention] This invention is a solar simulator in a light environment experimental device, that is, a rotation control device for an artificial solar device, more specifically, a solar simulator installed at the upper part of the experimental device is capable of rotational and tilting movement, and light is emitted from the simulator. Regarding the control device for reliably rotating the solar simulator with a small driving force in a device configured to irradiate the irradiation table with a light beam similar to sunlight, the gist of the device is to The rotation is connected to the movement of a balance weight set at a predetermined position, and the rotation of the simulator is controlled by the balance weight (i.e., movement with the same movement effect as the sun)
The aim is to ensure that this is done.

The present invention will be explained in detail below with reference to the attached drawings. A is a solar simulator with a light source, a reflective deflection plate, etc. installed inside, and a light beam/reflection deflection plate within the frame 1 to obtain a predetermined irradiation area. In the figure, left and right guides 3, 3 and up and down guides 4, 4 are installed on the frame 1 so that the provided light emitting unit 2 can be reciprocated from side to side and up and down.
The simulator A itself is configured to be able to perform horizontal and vertical reciprocating movements by a drive shaft 5.6 and a motor 7.8. It is integrally fixed to the support column 10.
．． 10 is fixedly supported integrally with a support shaft 11 which is installed horizontally at the lower end and is supported by a bearing of the machine base, etc., and the support shaft 11 is supported via a lever 12 and a shaft 13 etc. which are integrated with the support shaft. is connected to a rotary drive source C which is fixedly fixed, thereby supporting the support shaft 1.
1 in the direction of arrow H in Figure 1.
is configured to be able to rotate back and forth.

Therefore, for the operation of the solar simulator used in the solar house as described above, it is desired that the solar simulator rotates at the same speed as the earth's rotation, that is, extremely slowly and continuously. In order to obtain a predetermined irradiation area, the device shown in Fig. 3 must be moved in the horizontal and vertical directions, and the simulator A must also be rotated at a certain precise minute rotation angle. Moreover, the light emitting section must be stopped for a certain period of time until the operation of the light emitting section is completed at each rotation angle, which requires an extremely large holding force.

However, the weight of the simulator A is large, and since the support shaft 11 that is integrated with the simulator is fixed to the outside of the lower end of the support shaft 11, an excessive load is applied to the support shaft 11, and the simulator It is extremely difficult to rotate A with high precision and with a small drive as described above.

In this proposal, the above problem is completely solved by a control device that is linked to the simultaneous movement of simulator A.The control device is designed to react to the balance weight simulators installed at predetermined positions, so that simulator A A predetermined portion of the rotation mechanism and a balance weight are interlocked and connected so that the balance weight moves in the direction of inhibiting rotation of the simulator.

As shown in Fig. 1, in this case, a swinging balance weight 15 is installed integrally connected with a driven shaft 16 at the upper end of a support column 14 which is set up in a position that does not interfere with the rotation of the solar simulator A. 16 and the support shaft 11 are interlocked and connected by an appropriate transmission means such as a chain 17 or a belt gear, and the balance weight is simultaneously or slightly delayed as the simulator A rotates downward in the width direction of the arrow in the figure. 15 swings upward in the direction of the arrow 1 in the figure, and when the simulator A swings upward in the opposite direction of the arrow, the balance weight 15 is configured to swing downward, or the balance weight 15
The balance weight 15 is suspended and moved up and down, and when the simulator A rotates downward, the balance weight 15 is hoisted up to the driven shaft 16 and is raised, and conversely, when the simulator A rotates upward, it is configured to descend.

The balance weight 15 and the support shaft 11 in the simulator rotation device are connected by fixing the support shaft 11 and the driven shaft 16 integrally to a single chain and sprocket, a single belt and a pulley, or a support shaft 11.16. The interlocking connection may be made by meshing gears, or the interlocking connection may be made by using a chain 17 or a belt as shown in FIGS. 1 and 2, but as described above, It is an essential condition that the balance weight 15 be connected in such a way that it operates in the rotation suppression (control) direction of the simulator A.

Since the irradiation table B installed below the solar simulator A as described above is configured to be able to rotate horizontally in accordance with the rotation of the simulator, half-day irradiation can be done even during thermal full-day irradiation experiments. The range of movement is sufficient to reciprocate within the rotation angle (90'C) from the upright position shown in Fig. 1 to the rotational descent in the direction of arrow H until the horizontal position. Preferably, a hydraulic cylinder is used as shown in FIG.

When using rotational driving force like a normal motor, engine, etc., the drive shaft and the support shaft 11 are connected via a source gear and various types of converters for intermittent reversal as appropriate.

Reference numeral 18 in FIG. 3 indicates a brake, and reference numeral 19 in FIG. 1 indicates a supporting column for mounting a transmission mechanism such as a chain, which is erected and fixed on both sides of the solar simulator.

In the case of the embodiments shown in FIGS. 1 and 2, the operation of the present invention as described above is such that the simulator A is integrally moved with the support 10 in the direction of the arrow H by rotating the support shaft 11 with the rotation drive source C. At the same time, the rotational force of the support shaft is transmitted to the driven wheel 16 integrated with the balance weight 15 via the sprocket 20, the chain 17, the shaft 211 (sprocket) 211, the sprocket 23, the chain 17, and the sprocket 24. to swing the balance weight 15 in the upward direction while gradually rotating the simulator A to a horizontal state, or conversely, when rotating the simulator from a horizontal state to the upright state shown in FIG. The dynamic drive source C1 support shaft 11 is operated in the opposite direction to rotate the simulator in the upright direction, and at the same time, the balance weight 15 is swung downward from the raised state.

In this way, the movement control mechanism of the present invention has a balance weight of 15
is made to move in the direction of inhibiting the rotation of the simulator A by using the rotational driving force of the simulator A, so that the rotation of the simulator A can be controlled so that an excessive load is not applied to the support shaft 11, and the driving force is small. In addition, since the rotation of the simulator A is operated by the drive source C attached to the support shaft 11 at the bottom of the device, the movement of the support column 10 can be made accurate, and the center of gravity of the entire device can be adjusted. is placed downward, making it stable and compact.

Furthermore, the supports 10 and 10 are spaced apart from each other, and the balance way H
5 and 15 are also spaced apart from each other and also from the pillars 10 and 10, so that they do not interfere with the movement of simulator A and the irradiation, and furthermore, the swinging of balance weight 15 degrees 15 is in the direction of approaching or away from the direction of rotation of simulator A. Therefore, the stability of the device as a whole is good even when they rotate relative to each other.
