JPS6026358Y2 - Installation structure of solar collector on pedestal - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a so-called solar collector to a fixed frame for converting sunlight into heat, and particularly to one that pursues ease of attachment, durability, and robustness.

Solar collectors are generally installed on a stand at an angle in order to increase solar heat collection efficiency, and the solar collector itself weighs several tens of kilograms, making installation work on site complicated. and dangerous,
Ease of installation and robustness are required.

Furthermore, since the dimensional accuracy of the pedestal cannot be expected to be very high, it is necessary to make the mounting position variable so that dimensional errors in the pedestal can be flexibly dealt with.

Furthermore, since solar collectors are directly exposed to natural phenomena such as weather, they are required to have sufficient rust resistance.

Such rust prevention requires special consideration for frames using channels or angles made of mild steel or the like.

In this regard, in the conventional mounting structure shown in FIG. The solar collector 4 is attached to the pedestal 6 by inserting and tightening the mounting bolt 10 into the hole 7 and the elongated hole 9 bored in the other piece 8 of the connecting member 1 in the direction perpendicular to the pedestal axis. It corresponds to

However, in this case, it is necessary to drill the elongated hole 7 in the frame 6, which has poor corrosion resistance, so the elongated hole 7 must be treated with anti-rust coating, etc. The tightening force of the bolt is weak because the bolt is tightened with a screw, and even if a washer is used, it is still incomplete and the work becomes complicated due to the loss of the washer.

Further, the machining of such long holes itself causes an increase in machining costs.

Furthermore, a tapped hole must be made in the main casing 5 to screw the bolt 3, but since the main casing is a thin plate, the tapped hole penetrates through it, significantly reducing the waterproofness inside the solar collector. .

The heat collector mounting device described in Japanese Utility Model Application Publication No. 53-94336 is also an example of such a conventional device, and in this case, the heat collector mounting position is made variable by an adjuster fitting having a long hole. Similar to the example shown in FIG. 1, this type has various drawbacks such as the bolt tightening force, cost, and the necessity of drilling tapped holes in the main body casing.

Accordingly, the purpose of the present invention is to eliminate the need for using such long holes, etc.
In particular, it is an object of the present invention to provide a mounting structure that eliminates the need to drill holes in the pedestal, can accommodate dimensional errors in the pedestal in the vertical and horizontal directions, and is robust, rust-proof, and highly waterproof.

Next, specific embodiments of the present invention will be described based on the drawings.

FIG. 2 is a perspective view showing a mounting structure according to an embodiment of the present invention, and FIGS. 3 and 4 are a front view and a side view of the same mounting structure.

In these figures, reference numeral 11 denotes a fixed frame, and an L-shaped angle as shown in the figures or a C channel or the like is used.

The solar collector 12 mounted on the frame 11 has a box shape whose sides and bottom are surrounded by a main body casing 13 and a bottom plate 14', and a plurality of heat collecting plates whose bottom and sides are surrounded by heat insulating materials 14 and 15. 16 to collect solar heat.

Heat collecting plates 16, 16. A transparent plate 17 made of glass or the like that closes off the upper part of the main body casing 13 is pressed and fixed to the upper surface of the main body casing 13 by a mounting frame 20 via a bead 1B and a sealing material 9.

A bottom plate 14 having a C-shaped cross section and extending in the axial direction of the main body casing is disposed on the side surface of the main body casing 13 perpendicular to the frame 11.
A mounting groove 21 parallel to ′ is formed, and the mounting groove 21
Two bolts 23 and 23 are fixed to a rectangular mounting plate 22 which is slidable in the axial direction of the groove inserted into the rectangular mounting plate 22 .

One piece 26 of a connecting member 25 having an angular cross-section is in contact with the side surface 24 of the number mounting groove 21, and the two pieces bored in the
The bolts 23.23 are inserted into the holes 27.27,
The connecting member 25 is fixed to the side surface 24 of the mounting groove 21 by a nut 28.28 screwed onto the bolt 23.23.

A hook bolt 31 is inserted into a mounting hole 30 formed in the other piece 29 of the connecting member 25, and a bent end 32 of the hook bolt 31 is hooked onto the lower end of the frame 11.

Therefore, when the nut 33 screwed onto the hook bolt 31 is tightened, the pedestal 11 connecting member 25 is fixed via the hook bolt 31.

In addition, when the nuts 28 and 28 are loosened, the solar collector 12 itself is connected to the connecting member 25 fixed to the frame.
When the main body casing 12 is slidable in the axial direction as indicated by arrow 34 and the nut 33 of the hook bolt 31 is loosened, the connecting member 25 attached to the solar collector 12 is attached to the mount 11 as indicated by the arrow 35 together with the solar collector. The solar collector can be freely slid in the axial direction of the frame, and the solar collector can be mounted at any position in both vertical and horizontal directions with respect to the frame.

As described above, the present invention provides a structure for attaching a solar collector to a fixed frame via a connecting member.
A mounting groove is formed on the side surface of the main body casing of the above solar collector in a direction perpendicular to the mount to allow the connecting member to be slidably attached in a direction parallel to the bottom plate of the main body casing, and the connecting member is attached to the mounting hole drilled in the connecting member. The structure for attaching the solar collector to the stand is characterized by the bent end of the hook bolt being slidably attached to the lower end of the stand, so there is no need to drill long holes in the stand or connecting members. It can accommodate dimensional errors in the frame in either direction, has high corrosion resistance, reduces processing costs, provides a strong mounting condition, and does not require tapping holes in the main body casing itself.
The interior of the solar collector is completely waterproof, preventing deterioration in the performance of the insulation material and condensation on the surface of the transparent plate.
