【Example】

 Example 1. 1 is a diagram showing the overall configuration of a control device for an opening / closing plate material according to Embodiment 1 of the present invention. In the figure, 1 is a switchboard housing, 2 is a device housed in the panel, 3 is an intake port, 4 is an exhaust port, 5 is a cylinder, 6 is a piston, and 7 is provided so as to close the intake port 3; A possible intake port shutter, 8 is provided so as to close the exhaust port, an exhaust port shutter that can be moved up and down, 9 is a pulley, and 10 is a wire connected to each of the shutters 7 and 8 described above. It is connected to the piston 6 via a pulley 9. The cylinder 5 constitutes a heat-sensitive operating member, and operates so that the piston 6 projects in the direction of arrow A by being heat-sensitive according to the principle described later.

In the control device for the opening / closing plate material configured as described above, the in-panel temperature of the switchboard housing 1 becomes higher than the ambient temperature of the panel due to the amount of heat generated by the in-board storage device 2. According to the present invention, if the temperature inside the panel is below the allowable temperature of the storage device 2 inside the panel, the natural ventilation is stopped, and if it exceeds the allowable temperature, the cooling is performed by natural ventilation. The temperature change in the board is used by changing the pressure change due to the expansion and contraction of the substance in the cylinder 5 mounted on the upper part of the board into the force and movement amount acting on the piston 6.

In the present embodiment, when the temperature inside the board rises, the piston 6 acts in the direction of arrow A, and the intake port shutter 7 and the exhaust port shutter 8 which are connected by the wire 10 via the pulley 9 are closed. The intake port 3 and the exhaust port 4 are opened by moving in the arrow direction. With this, ventilation by natural convection is performed and the storage device 2 in the panel is cooled. Further, when the temperature inside the panel decreases, the piston 6 acts in the direction opposite to the direction of the arrow A, pulling up the intake port shutter 7 and the exhaust port shutter 8 in the direction opposite to the direction of the arrow B, and stopping ventilation by natural convection. . That is, the opening / closing plate is opened / closed by interlocking the opening / closing plate member composed of the shutters 7 and 8 provided so as to close the opening composed of the intake / exhaust ports 3 and 4 with the heat-sensitive operating member composed of the cylinder 5 which operates by heat. As a result, the intake and exhaust of air are minimized, pollution is delayed and maintenance is reduced. In addition, the automatic opening and closing of the opening and closing member is facilitated.

FIG. 2 is a sectional view showing details of the cylinder 5 according to the first embodiment of the present invention. The cylinder 5 is constructed as follows. That is, a rubber bag 5c for expansion and contraction is located on the bottom side in a cylindrical body 5b having a bottom 5a, and thermal expansion of, for example, olive oil, salt, mercury or the like having a large coefficient of thermal expansion is performed in this rubber bag 5c. The member 5d is stored. A cylinder 5f is provided at the center of the top plate 5e of the cylindrical body 5b, and a piston 5g is stored in this cylinder 5f. A pressure receiving plate 5h is provided at the lower end of the piston 5g, and the pressure receiving plate 5h is grounded to the rubber bag 5c. Reference numeral 5i is a spring for urging the piston 5g toward the rubber bag 5c. When receiving heat, the thermal expansion member 5d expands, the rubber bag 5c is enclosed, and the piston 5g is pushed up against the spring 5i.

That is, the temperature change in the board is used by changing the pressure change due to the expansion and contraction of the substance in the cylinder 5 attached to the upper part of the board into the force and movement amount acting on the piston 6.

When the thermal expansion coefficient of the thermal expansion member is monitored, the body expansion coefficient of olive oil at 20 ° C. is 0.721.

Therefore, in the present invention, gas may be used instead of liquid such as olive oil.

Example 2. In the first embodiment described above, the cooling by natural ventilation is described, but as shown in FIG. 3, the piston 6 projects and the wire 10 moves in proportion to the temperature inside the panel, so the limit switch 12 detects this. Then, the fan 11 is driven. That is, ventilation is not performed below Ta (° C), cooling is performed by natural ventilation when Ta (° C) to Tb (° C), and fan 11 is operated when Tb (° C) is exceeded and cooling is performed by forced ventilation. As described above, it becomes easy to effectively detect the temperature change in the panel due to the ambient temperature change and change the cooling method depending on the ambient temperature. In addition, the opportunity for fan operation can be reduced, and energy conservation and maintenance periods can be extended. The temperature Ta is 45 ° C., and the temperature Tb is 50 ° C., for example.

Example 3. In the first embodiment described above, the intake port 3 and the exhaust port 4 are opened and closed by interlocking the open / close plate member with the heat-sensitive operating member. However, as shown in FIG. 4, the intake port 3 and the exhaust port 4 are connected to each other. By attaching the bimetal 13a, which is formed by stacking the iron plate 13b and the acrylic plate 13c, as an opening / closing member, the bimetal 13a is displaced to the position 13f as the temperature inside the panel increases, so that the intake port 3 and the exhaust port 4 are opened, The opening / closing member is automatically opened / closed. As described above, since the opening / closing member is composed of the heat sensitive member, the number of parts is reduced and the structure is simplified as compared with the first embodiment.

Example 4. FIG. 5: is a figure which shows the window glass part of a building. The cylinder 5 of the present invention is attached to the wall 17 or the like at the upper part of the window glass 13 which receives the solar radiation.

In this embodiment, the present invention is applied to the opening M as a window of a building, and the opening M provided in the wall 17 of the building is closed by the window glass 13 and used for ventilation of solar radiation. Function. Support rods 19 extending upward and downward are provided on the left and right sides of the inside of the opening M, and the centers of the long blind plates 14a, 14a extending in the longitudinal direction are rotatably pivoted to the support rods 19. Supported. Reference numeral 16 denotes an angle adjusting drum rotatably and pivotally mounted on a support rod 19, to which a blind angle adjusting cord 15 is hung, and the cord 15 hangs downward so that one side of the blind plate 14a, 14a is connected to one end and the other side is connected to the other ends of the blind plates 14a, 14a. The angle adjusting drum 16 rotates in the direction of arrow F to rotate the blind plates 14a, 14a in the closing direction, and in the opposite direction. Displace as shown and rotate in the opening direction. The piston 6 and the angle adjusting drum 16 are interlocked via a pinion rack mechanism (not shown), and when the piston 6 projects, the drum 16 rotates in the arrow F direction.

That is, the angle of the blind 14 is changed by rotating the blind angle adjusting drum 16 using the same action as described above when receiving the solar radiation.

According to the fourth embodiment, the sunlight rays from the window glass 13 can be automatically shielded, and the manual opening and closing can be omitted.

[Effect of device]

 As described above, according to the control device of the opening / closing plate material of claim 1, the opening / closing plate material provided so as to close the opening portion is opened / closed by interlocking with the heat-sensitive operation member that operates by heat. Since the opening / closing plate material is opened only when it is heat-sensitive, it is possible to obtain an effect that contamination is delayed and maintenance is easy.

According to the control device of the second aspect, since the opening / closing plate member provided so as to close the opening is made of a bimetal which operates by heat, the opening is opened and closed. Under this condition, the effect that it can be automatically opened and closed is obtained.

According to the control device of the third aspect, since the opening portion is configured by the intake and exhaust ports of the switchboard housing or the window of the building, these can be automatically opened and closed.
