Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat collector, and particularly to a structure for attaching a transparent plate to a solar heat collector casing.

This type of structure conventionally used is shown in FIGS. 1-3.

In Figure 1, sealing materials or gaskets 2' and 3' are arranged in a sandwich pattern above and below the outer edge of a transparent plate 1', and a transparent temporary retainer with an L-shaped cross section is applied from above the upper gasket 3'. Material 4'
The gaskets 2' and 3' are covered with gaskets 2' and 3' and tightened to the side wall frame 7' of the casing 6' of the solar heat collector using screws 5' etc. to protect the transparent plate 1' from rain. Since it is impossible to apply sufficient pressure in the vertical direction, there is a drawback in sealing performance.

In Figure 2, screw 5' is installed perpendicularly to the upper surface of transparent temporary holding material 4' in order to apply sufficient pressure to gaskets 2' and 3'. Rainwater easily enters through the holes, and there is a risk that the entered rainwater may flow along the upper surface of the side wall frame 7' and enter the inside of the heat collecting device.

In FIG. 3, a light-transmitting plate support portion 8' that protrudes upward from the upper surface of the side wall frame 7' is erected to prevent the rainwater that has entered into the heat collecting device from entering the inside of the heat collecting device. A screw attachment portion 9' is provided upright outside the transparent plate support portion 8' on the upper surface.

Rainwater that has entered through the screw holes of the screws 5' is prevented from entering the heat collecting device by the tall transparent plate support part 8', and passes through the drain hole 10' provided at the base of the screw mounting part 9'. The liquid flows through a channel 11' formed between the transparent temporary holding material 4' and the screw attachment part 9' and is appropriately discharged to the outside.

The conventional example shown in Figure 3 seems to have an almost perfect structure, but
Similar to the conventional example shown in FIGS. 1 and 2, a large number of screws are used to attach the transparent temporary holding material.

On the other hand, heat collectors are usually installed on a sloped surface facing south, such as a roof.

Therefore, when a strong north wind blows against this, negative pressure acts on the light-transmitting plate on the leeward slope, and a force acts on the light-transmitting plate.

In order to overcome the above problems, the diameter of the screw and the length of the screw portion had to be increased, which tended to make the screw seat of the screw thicker, which in turn led to an increase in the weight of the casing.

Heat collectors are originally installed on roofs with low strength, and an increase in weight is extremely undesirable from the viewpoint of handling.

The present invention has been made in view of the drawbacks of the conventional structure.According to the present invention, a transparent plate support portion that supports the lower surface of the transparent plate is provided on the inner edge of the upper surface of the side wall frame of the box-shaped casing that is open at the top. At the same time, an engaging part that engages with the transparent temporary holding material is formed near the center of the upper surface of the side wall frame body, and an engaging part that engages with the above-mentioned engaging part is formed near the center of the lower surface of the transparent temporary holding material. When the engaging part of the transparent temporary holding material is engaged with the engaging part of the side wall frame after the above-mentioned transparent plate is placed on the transparent plate supporting part, A wedge material is press-fitted between the lower outer edge of the temporary holding material and the upper outer edge of the side wall frame of the casing, so that the transparent plate is inserted between the transparent plate support and the lower inner edge of the transparent temporary holding material. The present invention provides a structure of a solar heat collecting device in which the solar heat collecting device is closely sandwiched between

Hereinafter, the present invention will be described with reference to embodiments with reference to the accompanying drawings.

As shown in FIGS. 4 to 6, header pipes 2.2 are connected to the ends of heat collecting pipes 1 arranged at predetermined intervals, and heat collecting plates 3 are assembled between the heat collecting pipes 1. The heat collector is attached to the casing 4 to form a heat collector, which is housed in the casing 4.

Reference numeral 5 denotes a supply/drainage cap attached to the end of the header pipe 2 and protruding outward from the casing 4.

The heat collecting pipe 1 is made of a metal material with good thermal conductivity such as copper, and is made of a metal material with good thermal conductivity such as copper, and the heat collecting plate 3 is made of an extruded material such as an aluminum alloy, and the surface facing the sun is painted black. Or perform endothermic treatment such as selective absorption membrane.

The casing 4 has a box shape with an upper opening and is composed of a side wall frame 6 and a bottom plate 7, and the side wall frame 6 and the bottom plate 7 are joined with pot rivets 8 or the like.

A translucent plate support part 9 having a C-shaped groove etc. on the upper part is erected on the inner edge of the upper surface of the side wall frame 6 of the casing 4. A gasket 10 is fitted into the C-shaped groove 9A of the support part 9 and placed on the gasket 10. The lower edge of the transparent plate 11 is placed.

Further, near the outer edge of the upper surface of the side wall frame 6, a protrusion 12 having a substantially ]-shaped cross section is provided upright.

The protrusion 12 has at its upper end an arcuate recess 13 constituting a downwardly directed engaging portion.

On the other hand, the light-transmitting plate holding member 14 has a long side portion 14A that is substantially parallel to the top and bottom.
and a short side part 14B, and is formed in a square cross section, and the free end of the short side part 14B has an arcuate part 15 constituting an engaging part that fits into the arcuate recess 13 of the protrusion 12. Be prepared.

It is preferable that the arcuate portion 15 is formed to have a circular cross section so that it can rotate smoothly within the arcuate recess 13.

During installation, the arc portion 15 of the transparent temporary holding material 14 is fitted into the arcuate recess 13 of the protrusion 12, and the long side 14A of the transparent temporary holding material 14 and the transparent plate support portion are first fitted. Translucent plate 1 placed on 9
1 and another gasket 16 is inserted between the two.

In this state, the force that clamps the transparent plate 11 is not yet acting on both gaskets 1° and 16.

Next, a rod-shaped wedge member 17 made of aluminum alloy, synthetic rubber, or the like is press-fitted from the outside between the short side 14B of the transparent temporary holding member 14 and the outer edge of the upper surface of the side wall frame 6 of the casing 4.

When the wedge material 17 is press-fitted, the transparent temporary holding material 14 is rotated by the lever principle using the contact line between the arc-shaped recess 13 and the circular arc portion 15 as a rotational fulcrum, and the transparent temporary holding material 14 The gasket is strongly pressed by the inner edge of the lower surface of the long side portion 14A to tightly sandwich the transparent plate 11 between the gaskets 10 and 16.

Furthermore, even if rainwater enters between the upper gasket 16 and the transparent plate 11, it will flow through the channel part 18 between the transparent plate support part 9 and the protrusion 12, and the notch 19 shown in FIG. through which it is discharged to the outside.

FIGS. 9 to 14 are diagrams showing another embodiment of the present invention, and the same parts as in the above-described first embodiment are given the same reference numerals.

The embodiment shown in FIGS. 9 and 10 differs from the first embodiment in the position where the arcuate portion 15 protrudes from the light-transmitting temporary presser 14, and FIGS. Arc portion 15
The directions are different from each other.

In the embodiment shown in FIG. 11, the arcuate recess 13 does not directly protrude from the center of the upper surface of the side wall frame 6, but is formed by bending from a protrusion 12' formed on the outer edge of the side wall frame.

In the embodiment shown in FIG. 12, a descending step is formed from near the center of the upper surface of the side wall frame 6 toward the outer edge, so that the protrusion 12 is made to protrude outward, and an arcuate recess 13 is formed at the tip of the protrusion 12. It is.

The embodiment shown in FIGS. 13 and 14 is a press-fitted wedge material 17.
In order to prevent the slider from falling off during use, engaging portions 20 and 21 for engagement with wedge members are formed on the light-transmitting temporary holding member 14 and the side wall frame 6, respectively.

Even when replacing the transparent plate due to breakage, etc., it can be disassembled with one hand by raising one end of the wedge and pulling it out.

The present invention is constructed as described above, and instead of using screws as in the conventional structure, a wedge material is used instead. Therefore, even if the holding material and side wall frame are made thinner and lighter in structure, sufficient strength can be achieved. It is extremely easy to assemble and disassemble.

Also, unlike the conventional screw structure, which requires point contact at intervals, the long rod-shaped wedge member provides uniform line contact, resulting in a complete watertight seal.

Furthermore, since the engagement portion between the light-transmitting temporary holding material and the protrusion is located on the side surface of the casing, there is little water leakage from here.

Further, according to the embodiment, even if rainwater enters between the upper gasket and the light-transmitting plate, it can be drained to the outside through the channel portion, and has many advantages.
