Description

[Detailed Description of the Invention] The present invention relates to a solar heat collection device that collects sunlight energy and uses it as a water heater or the like.

More specifically, a fall prevention plate that doubles as a reflector is installed at the bottom of the collector, and it can be installed on a steep slope on a balcony to efficiently collect solar heat, and in the event of a typhoon, etc., it can be reduced with a simple operation and is safe. This is an attempt to increase heat and collect heat.

Conventionally, solar heat collectors are installed on the roof of a house to collect solar heat, but since the intensity and angle of sunlight differ in summer and winter, it is necessary to set the collector at a gentle slope to suit the summer season. A reflector was placed on top of the collector to collect heat during the winter.

However, if the above solar heat collector is placed at a steep slope on the wall or balcony of an apartment building, the heat collection efficiency will be significantly reduced in the summer due to reflection from the surface of the collector, and the reflector is fixed. This has the disadvantage that sunlight can only be reflected and heat collected during a portion of the daylight hours that change over time.

In addition, since the surface of the collector is made of a sunlight-transmitting material such as glass, if the glass breaks, the broken pieces may fall and pose a danger to the floor below, making it unsuitable from a safety point of view. Met.

There is a technique described in Japanese Utility Model Application Publication No. 162062/1983 that allows the angle of the reflecting plate to be changed in order to correspond to the change in the sunlight angle.

This technology is related to electric water heaters that use solar heat.
A reflective plate that reflects sunlight is provided on the front of the heat receiving surface of the metal tank so that the reflection angle can be changed, and fixed reflective plates are provided on the top, bottom, left and right of the heat receiving surface.

There are devices that obtain solar heat by reflecting sunlight onto a heat-receiving surface using these multiple reflectors, but since the front reflector is opened and closed in a spread shape using arc-shaped metal fittings, there are disadvantages of high manufacturing costs and It is dangerous if the front reflector is installed protruding from the balcony during periods of strong winds such as 2018 or typhoons such as autumn, and it has no choice but to close during this period, preventing the original heat collection from occurring. There were also drawbacks that impaired the effectiveness.

The present invention was developed in view of the slope, and is installed at a steep slope on a balcony etc., and by configuring a fall prevention plate that also serves as a reflector at the bottom of the collector so that the reflective part can be reduced or expanded, the collector surface The purpose of the present invention is to provide a solar heat collection device that can efficiently and safely collect sunlight depending on the season, whether there is strong wind or not, while also preventing danger to the lower floors due to broken glass, etc. .

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

However, embodiments of the present invention are not limited thereto.

In each figure, 1 is the solar heat collecting device according to the present invention, 2 is the collector that constitutes this, and the lower part is a reflective plate made of metal etc. that reflects the end of the stainless steel to prevent falling. A plate 3 is connected to the collector 2 with a shaft 4 interposed therebetween.
It is mounted rotatably relative to the

Further, as shown in FIG. 2, the fall prevention plate 3 has a reflective portion 3a.
and 3b, and the reflective part 3b is configured to be slidable inside the reflective part 3a, and the reflective area of the fall prevention plate 3 (and the area of the wind receiver) can be increased or decreased.

Reference numeral 5 is for regulating the angle of the fall prevention plate 3 provided at the bottom of the collector, so that the angle of the fall prevention plate 3 is regulated so that it remains above horizontal even if it rotates with respect to the above-mentioned shaft 4. It was made in 1997.

7 is a support member for supporting and fixing the solar heat collector 1 on a balcony or the like, and a concrete 8 on the balcony or the like.
This is a member that supports and fixes the embedded solar heat collector 1.

Since the present invention is configured as described above, for example, the solar heat collecting device 1 is fixed on the balcony using the support member 7,
The fall prevention plate 3, which also serves as a reflector, may be rotated to adjust the reflection angle so that sunlight can be collected by the collector 2.

In addition, the fall prevention plate 3 expands and contracts the reflective part 3b housed in the reflective part 3a according to the strength of the wind that accompanies seasonal changes, increasing and decreasing the area of the wind receiver to improve safety. What is necessary is to improve the heat collection efficiency.

The representative embodiments of the present invention have been described above, but it goes without saying that the fall prevention plate 3 which also serves as a reflector in the present invention may be fixed to the collector 2 at an angle of 90°, for example.

According to this invention, since a fall prevention plate is provided at the bottom of the collector that also serves as a reflector, it is possible to efficiently collect sunlight to the collector even if the collector is installed on a steep slope such as a balcony. Even if, for example, the surface of the collector is crushed due to an accident, the fall prevention plate can prevent the crushed pieces from falling to the lower floor, making it extremely safe even when used on the balcony of an apartment complex.

In addition, since the two reflective parts that make up the fall prevention plate are configured to be slidable, the reflective parts can be slid to expand and contract to increase or decrease the area of the wind receiver, allowing the wind to change depending on the season. It is possible to obtain appropriate solar heat by adjusting the reflected solar light by taking into account the wind pressure due to the strength of the wind, and it is possible to efficiently collect sunlight to the collector with a simple configuration of two sliding reflective parts. It can be manufactured at low cost.
