Abstract

PURPOSE:To easily and securely shield light when it is not necessary to collect heat and easily and securely focus light when collecting heat, by providing a reflecting plate capable of being rotated between a closed condition and an open condition of a surface of a heat collector provided with a transmitting body at an upper part thereof. CONSTITUTION:A box form heat collector 21 provided with the transmitting body 22 at an upper part thereof is placed on a slanted surface of a stand 24. The reflecting plate 26 is pivotally supported by a supporting means 27 provided at the lower end of the stand 24 through a rotary shaft 28 so that the plate 26 can be rotated between a condition of covering the surface of the heat collector 21 and a condition of opening the surface. In this case, the opened condition of the plate 26 is supported by the supporting means 29 to set an open angle. In the closed conditon of the plate 26, the tip of the plate 26 is supported by a supporting means 30 provided at the top of the stand 24. When it is not necessary to collect heat, the surface of the heat collector 21 is covered by the reflecting plate 26. On the other hand, when collecting heat, not only the sun light is projected directly to the transmitting body 22 but also the reflected light from the plate 26 is projected to the body 22, whereby heat-collecting efficiency is enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat collecting device, which not only receives and receives light from a transparent body 11Cw when necessary, but also utilizes a reflector to effectively collect heat, and when not needed, The idea is to apply the reflector in reverse and use it as a shielding plate to prevent sunlight from passing through the transparent body.

As shown in Figures 1 and 2 of the conventional Kiyo gravel collection device rj, a transparent body (tl) is placed on the top,
Base #Ii by tilting the heat collector (3) equipped with the mounting legs (2) at the bottom! (4) Reinstall the mount (5) on the slope of J: and attach a light-shielding sheet (6) made of cloth or the like to block sunlight to the upper end of the mount (5) (V-) for complete winding. A support (8) supporting the winding shaft (7) is fixed.

One end of the saliva base sheet (6) is a sheet rolled up m (7)
The other end is attached to the wire (9). The wire (5) is attached to a wire winding shaft 11) supported by a support DDVC fixed to the lower end of the pedestal (5). Therefore, when mixing heat, l/c as shown in Figure 1
The light shielding sheet (6) is wound around the sheet numbering shaft (7),
The front surface 1c of the transparent body (1) of the water tank (3) has no impediments, so it can collect heat normally, and the unnecessary TJ8# can be shielded from light by winding the wire (9) manually or electrically. sheet-
6) comes down and covers the transparent body (1) of the heat collector (3), as shown in Figure 2, so that it cannot be drained. By the way, this aT! At t1c, if a large number of heat collectors (3) are used for commercial purposes, the strict light device that is only used occasionally becomes a very expensive item. Since it was for one purpose only and was not useful during the light, it seemed overpriced.

The present invention has been made to eliminate these conventional problems, and uses a reflector to increase the concentration of solar heat in the heat collector. When the heat medium circulation pump of the 41st period is broken or the load ρ is low due to the off-season, etc., the 4VC reflector plate is reversed and placed over the heat collector SI]Ii to use it as a light plate. A heat collector equipped with yc is installed on a pedestal, a reflector plate is provided that is rotatable between a closed state and an open state on the surface of the collector, and a support for regulating the opening angle of this reflector plate is provided. The ingredients were supplemented.

The present invention has the above configuration, so that when collecting solar heat, the reflector f! :The nest can be left open with its sides open and supported by a support that regulates the opening angle. The reflected light also enters, and as a result, secretion can be collected effectively. Also, when not in use, rotate the reflector around the reminiscence monk to the surface side of the collector, and set = 4p! By changing the surface of the vessel from an open state to a closed state, the reflecting plate acts as a light shielding plate, which prevents sunlight from passing through the transparent body.

In the following, an embodiment of the present invention will be explained based on the drawings (FIGS. 6 and 4). 211 is a box-shaped drain with a transparent body on the top, and a mounting plate is attached to the bottom. (211 is the VC installed directly above the slope of the pedestal E. G is the four foundations that receive the pedestal. 1261 is pivotally supported by the rotation axis with respect to the supporter at the lower end of the pedestal. This reflector +261
Covering the surface of (7L collector 2) (closed state)
And a collector! ! The surface of υ can be rotated between the open state and the open state. A support for supporting the closed state of the 4μ reflector plate and setting the opening angle. (A) is a support installed at the top of the mount that supports the tip of the reflector @ when the reflector plate is in the closed state. It is a ingredient. Although not shown, in order to prevent the reflector from being excited by wind, etc., attach the reflector to the support with screws, locks, etc.
VC is set to fix it. Therefore, there is no need to collect heat.
ζ, If the surface of the heat collecting acn is covered with the reflective plate (261), the reflective plate (261) will act as a light shielding plate and will not collect heat. To,
Since the light reflected by the reflector also enters, the heat collection effect can be enhanced.

The solar heat collection rigidity of the present invention can be implemented as described below, and the following effects can be obtained.

■ During construction, inspection, breakdown, etc., by placing a reflective plate over the surface of the dust collector, it has a light blocking effect and prevents dry firing of the collector #I. Also, when the heat medium etc. in the heat collector is not circulating, 'Ic can prevent the heat medium etc. from boiling.

■ During the construction period, the soil may be cured until the start of operation, which can prevent pollution from water and dust.

■ Even if roof tiles or other objects fly during a typhoon, covering the surface of the dust collector with a reflective plate can prevent damage to the transparent body of the dust collector.

■ When the reflector is open, the light reflected by the reflector is incident, so the amount of heat collected can be improved.

■ As a reflector for Ji-Cen-Pai, switching between the reflector and the light-shielding plate when heat collection is not required can be done in a relatively short time with occasional operations.

■ In the example, the rotating shaft of the reflector is located at the bottom of the heat collector, but if a VC is provided at the top of the collector, the VC can be placed on the back of the reflector and the dust collector. If it is tightened, it will act as a windbreak and reduce the amount of radiation from the heat collector.
