Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel solar energy collector for installation on a roof, and in particular to a solar energy collector (hereinafter simply referred to as a collector) with improved energy collection efficiency and ease of assembly.

Traditionally, solar energy collectors have been used. (For example, Japanese Unexamined Patent Publication No. 52-35341 and Utility Model Application No. 52-35341)
(Refer to Publication No. 52134) In the former case, the solar energy collector is partially buried in the heat insulating material, which has poor thermal efficiency, and the cover glass frame is made of a single plate, so if the cover glass frame is damaged, the entire plate must be replaced. I didn't have to. In the latter case, the solar energy collector is fitted into a notch in the roof structure, which has the disadvantage that rain can enter through the gap. In addition, there was another conventional example (for example, see JP-A-54-158736) in which cover glasses were arranged side by side, but in this case, if the cover glasses had different dimensions,
There was some wobbling when fitting, and the upper part of the connecting member had weak elasticity, making it easy for the cover glass to come off even if it was fitted.

The purpose of the present invention is to improve the energy collection effect of the collector, improve the efficiency of collector assembly work, and improve rain protection. At the same time, the vertical beam of the cover glass frame is fitted to the support part formed by
There is a collector equipped with a solar energy collection device below the cover glass frame.

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

FIG. 1 shows a metal roof equipped with a solar energy collector according to an embodiment of the invention, 1 the collector installed on one half of the roof, 2 the connections carrying the cover glass frame, which will be described in detail later. A solar energy collection device is disposed below the cover glass frame. 3 is the eave cover material, 4 is the ridge member, 2'
indicates a connecting member on the side of the roof.

The roofing material constituting the metal roof on the side where the collector 1 is installed has a heat insulating material 9 between the metal plate (preferably an aluminum alloy plate) 7 on the surface and the base material 8 on the bottom, as shown in the cross section in Fig. 2. A connecting extension part formed of a main body part 10 interposed in a sandwich-like configuration, and a metal plate 7 extending horizontally along the side end surface of the main body part 10 and then horizontally outward from the side edge of the bottom base material 8. 1
1, and a low rising portion 12 is provided at the outermost edge of the connecting extension portion 11. Also metal plate 7
has longitudinal protrusions 13 on its surface and small irregularities 14 between them, and its overall shape is simpler than that of conventional structures. As shown in FIG.
, and a draining wall profile 6 (FIG. 4) is attached to the ridge as will be described in detail later. Therefore, the rising portions 12 provided on the side edges of adjacent roofing materials are connected to each other via the connecting member 2 to form the roof on the side where the collector 1 is disposed (FIG. 18).

Next, a horizontal bar for attaching a solar energy collection device,
Connecting members 2, 2' to which the cover glass frame is fixed
I will explain about it.

As shown in FIG. 5, the connecting member 2 in this embodiment has a main body with a generally groove-shaped cross section, which is composed of vertical walls facing each other and a bottom wall connecting the two, and supports are provided on both sides of the main body. Groove 15 and support section 16 above it
are provided to protrude upward and integrally with the main body, and the cover glass frame is attached to the connecting member 2 via the support portion 16. Further, drain grooves 116 formed between the vertical wall of the main body and the support grooves 15 and 16 respectively form drainage channels for condensed water. Then, cover 1 covers the upper opening of the main body.
7 is adapted to be mounted on the main body by engaging its inner leg piece with a protrusion on the vertical wall 121 of the main body. Further, the connecting member 18 is fitted between the vertical walls 121 of the connecting member 2 by engaging the engaging edges at both ends in the engaging grooves 118 provided in the middle part of each wall, thereby reducing the elasticity of the upper part of the connecting member 18. I'm trying to improve it. Figure 6 shows the cross-sectional shape of the outermost connecting member of the collector, the inner half being constructed similarly to that shown in Figure 3, but the outer half being a solar energy collector. Or, while it is widened to provide room for accommodating related elements such as supply and drain pipes, it lacks the outer support groove 15 and the support part 16 and is flattened. In FIG. 6, elements corresponding to those in FIG. 5 are shown with the same numerals appended with '' to distinguish them.

The connecting members 2, 2' having the above configuration have a rising portion 12
The connecting member 2, 2' is mounted and fixed between the metal roofing members connected together via the connecting member 2, 2', and a horizontal beam 37 for mounting the solar energy collecting device is attached to this connecting member 2, 2'. That is, as shown in FIGS. 18 to 20, a required number of horizontal beams 37 are installed at the connection site of each cover glass frame extending from the ridge toward the eaves and at a height above the roofing material, as described later. In the horizontal position, the connecting members 2 and 2' are attached perpendicularly between adjacent connecting members 2 and 2' (hereinafter simply referred to as connecting members 2 and 2'), forming an intersecting structure. This horizontal bar 37 has bolts 42 at both ends to connect the connecting member 2,
2', the shaft portion of the bolt 42 is loosely fitted into the bolt insertion hole in the flat plate portion of the horizontal beam 37. Specifically, as shown in FIG.
is held in a fitted state in the grooves at both ends of the groove-shaped portion of the horizontal bar 37 by a holding member fixed to the upper surface with a bolt inserted through the slot 40, and the horizontal bar 37 is connected to the connecting member 2,
2' so as to be movable in the longitudinal direction.

Note that 39 is an energy dissipation prevention means, such as a heat insulating member, which is interposed between the horizontal beam 37 and the solar energy collection device, and is designed to block heat transfer between the two and prevent the collected energy from dissipating to the outside. ing.

Next, FIGS. 12 to 14 show the connection member 2,
15 and 17, the ridge cover glass frame, the eaves edge cover glass frame, and the middle cover glass frame are shown, which constitute the cover glass frame to be assembled to the roof ridge 2'. The connecting members 2, 2' are successively connected to each other from the top to the eaves through vertical bars, which will be described later.
2' (Fig. 29).
First, the ridge cover glass frame (FIG. 12) consists of an upper ridge section 22, an intermediate lower section 21, and a pair of vertical sections 19.
(shown in FIGS. 10, 9, and 7, respectively), between the upper and lower horizontal parts protruding from one side of each, for example, in the case of the vertical crosspiece 19, parallel to each other connected at the vertical part 25. The peripheral edge of the cover glass G is sandwiched between the upper horizontal part and the lower horizontal part 27 of the cover glass via a gasket, and the ends of each crosspiece are joined together so that the whole has a rectangular shape in plan view. Similarly, the intermediate cover glass frame and the eaves edge cover glass frame are connected to each other by sandwiching the glass G between the upper and lower horizontal portions of each frame that forms the periphery of these frames, and are combined into a rectangular shape in plan view. It is adapted to be fitted into the connecting members 2, 2'. However, for the middle cover glass frame, the upper crosspiece 2
In place of 2, the intermediate upper crosspiece 20 in FIG. 8 is used, and in place of the upper crosspiece 22 and lower crosspiece 21 in the cover glass frame at the eave edge, the intermediate upper crosspiece 20 in FIG. 8 and the lower eaves lower crosspiece in FIG. 23 is used. In addition, as the frame of these cover glass frames, extrusion molding of aluminum alloy is preferably used.

Furthermore, in this embodiment, in order to improve the solar energy collection efficiency, energy dissipation prevention means, such as a heat insulating partition member, is arranged along the periphery of each cover glass frame at a lower position of each cover glass frame. First, as shown in FIG. 21, a vertical partition member 43 is attached to the side of the connecting members 2, 2' parallel to the side edges of the cover glass frame. The member 43
As shown in FIG. 25, it has a structure in which a heat insulating material 48 having a substantially trapezoidal cross section is integrated into the inside of an outer plate 47 made of aluminum alloy thin plate and having a substantially U-shaped cross section. Mounting fittings that engage with the support grooves 15 and support portions 16 of the connecting members 2, 2' are fixedly installed at both ends of the wall and the lower wall, and the member 43 is attached to the connecting members 2, 2' via these fittings. It is designed to be installed. This vertical partition member 43 is located at a side edge position of the cover glass frame and extends in the height direction between the opposing surfaces of the frame and the horizontal bar 37, and blocks energy dissipation to the side of the solar energy collection device. are doing.

In addition, the upper and lower edges of each cover glass frame are marked with the markings shown in Figure 22~
As shown in FIG. 24, a ridge partition member 44, an eaves partition member 45, and an intermediate partition member 4
6 are respectively fitted to block energy dissipation from the solar energy collection device towards the ridge and eaves as well as dissipation through the gap between the cover glass frames. The heat insulating partition members in the ridge, eaves, and intermediate portions each have a structure in which a heat insulating material is loaded inside an extruded aluminum profile as shown in FIGS. 26 to 28.

The details of each cover glass frame and each of the partition members 43 to 46 described above will be explained below along with the procedure for attaching them to the connecting members 2, 2', etc. Note that, prior to the installation of these elements, the connecting members 2 and 2' are placed between the mutually connected roofing members, the horizontal beams 37 are fixed to the members 2 and 2', and the solar energy collection Equipment such as water supply and drainage pipes are attached. Next, the above-mentioned vertical partition member 43 (FIG. 21) connects the connecting member 2,
It is attached via a mounting bracket that engages with the support portion 16 and support groove 15 of 2'. Moreover, the ridge partition member 44 (FIGS. 22 and 26) is arranged on the ridge cover glass frame by fitting the bottom notch into the water supply and drainage pipe and fitting the bottom engagement recess into the corresponding engagement protrusion. On the other hand, the eaves partition member 45 (FIGS. 24 and 27) is similarly arranged at the lower edge of the eaves track cover glass frame, and the intermediate partition member 46 has a half cross section. The upper half of the supply and drain pipes are fitted into the circular bottom notch holes and placed at the joining site of the cover glass frame.

After assembling and arranging the above-mentioned elements, the cover glass frames shown in FIGS. 12 to 14 are sequentially installed between the connecting members 2 and 2 via the vertical bars 19, starting from the one on the eaves side, for example. Ru. During installation, the second
As shown in Fig. 9, it is sufficient to simply fit the hanging legs 24 of the vertical beam 19 into the grooves of the support parts 16 of the connecting members 2, 2', and there is no need to mechanically connect the two as in the conventional type. , work efficiency has been improved. In the eaves cover glass frame fitted to the connecting members 2, 2' in this way, the eaves partition member 45 is connected to the lower crosspiece 23 with bolts inserted through the insertion holes at both ends of the upper wall. The seal attached to the downward protrusion 36 (Fig. 11) of the crosspiece 23
3 and the upper wall of member 45 are sealed. Furthermore, the eaves edge cover glass frame is attached to the lower horizontal part of the eave edge lower crosspiece 23 via the eave tip of the partition member 45 to the ridge side edge of the positioning metal fitting 54 (FIG. 33) fixedly installed on the upper surface of the roof material. It is designed to be positioned by bringing the tips into contact. In addition, a rising part 30 is formed on the ridge side end of the lower parallel surface 29 of the intermediate upper crosspiece 20 (FIG. 8) forming the upper edge of the cover glass frame at the eaves edge, and this rising part 30 is used to cover the intermediate part. A partition member 46 is fixed to the glass frame (FIGS. 24, 30, and 31).

Next, the intermediate cover glass frame adjacent to the eaves cover glass frame is fitted to the connecting members 2, 2' in substantially the same manner as the eaves cover glass frame, but the intermediate lower crosspiece 21 forming the lower edge of the frame is fitted to the connecting members 2, 2'. The adjustment mounting plate 148 connects the front end of the plate 148 on the eaves side to the intermediate partition member 4.
It is attached so that it can come into contact with the outer surface of the ridge side of No. 6, and the 30th
When the intermediate cover glass frame is attached to the eave edge cover glass frame as shown in FIG. 31 from the separated state shown in the figure, the position of the intermediate cover glass frame relative to the eave edge cover glass frame is defined.
After both glass frames are placed in a predetermined position, they are connected by a connecting fixing rod 51. That is, as shown in FIG. 32, groove structure forming means 49 are fixed to the vertical beam 19 of the cover glass frame at the eaves and the lower beam 21 of the middle cover glass frame, respectively, so that the groove passages 50 of each are aligned with each other. Then, the rods 51 inserted into the groove passages 50 are fastened with bolts 52, and both glass frames are easily and reliably fixed in the predetermined positions. At this time, the lower rail 21
The upper surface of the upper edge of the upper crosspiece 20 is covered with a cover portion 31 extending long toward the eaves, thereby forming a waterproof structure. (Figure 31).

Next, another intermediate cover glass frame is fitted onto the connecting members 2, 2' adjacent to the already installed intermediate cover glass frame, and both glass frames are joined with the intermediate partition member 46 interposed therebetween. This fitting and coupling is done in the same manner as described above, so the explanation will be omitted.

Furthermore, the ridge cover glass frame is connected to the connecting members 2, 2'.
The lower crosspiece 21 is connected to the upper crosspiece 20 of the adjacent intermediate cover glass frame in the same manner as described above. On the other hand, the ridge upper crosspiece 22 is
As shown in Figure 9, its upper edge is fastened with a bolt 69 to a connecting metal fitting fixed to the connecting member, and the space between the upper crosspiece 22 and the connecting metal fitting is sealed with a sealing material attached to the downward protrusion 33 on the lower surface. The ridge partition member 44 is fastened to this connecting fitting with bolts inserted through both ends of the upper wall of the member 44, which has an L-shaped cross section.

In order to further securely fix each cover glass frame fitted to the connecting members 2, 2' as described above, the rising portion 26 of the vertical bar 19 (FIG. 7) of each frame is
The tip of the cover 17 is adapted to engage with a side edge engaging recess of the cover 17. A small protrusion 28 is provided at the tip of the extension 27 inside the lower horizontal portion to form a flow channel on the bottom surface of the horizontal portion to facilitate drainage of dew water.

Next, as shown in FIGS. 34 and 35,
An eaves shape member 58 in which a lower end bent protrusion of an eaves front cover member 57 formed by integrally bonding a heat insulating part 56 as an energy dissipation prevention means to the inner surface projects outward from the eave tip edge of the roof body. is fitted to, and
At the bent portion of the upper end of the member 57, the edge of the eaves of the upper surface cover member 55, one end of which is fitted between the upper wall of the lower crosspiece 23 and the upwardly inclined wall 34, is inserted into the groove hole 158 of the edge of the eaves.
The member 57 is fixed by a bolt 59 inserted through the eaves, and the member 57 forms a waterproof structure in cooperation with the lower eave edge member 23. As shown by broken lines in FIG. 35, a plurality of drainage holes 60 are provided at appropriate locations on the lower surface of the bent protrusion at the lower end of the front cover member 57 for the eaves to completely drain the condensed water from the eaves. We are expecting.

Figures 36 to 38 show how to treat the tips of the connecting members at the eaves, and the front parts of the connecting members 2, 2' are used to accommodate the water supply pipe 61 and drain pipe 62 that form part of the solar energy collection device. is notched, and above the front part, the connecting members 2, 2'
The connecting member 63 interposed between the upper parts of the vertical walls is fixed using a fastener 64, and the Z-shaped mounting piece 67 fixed to the inside of the upper part of the cap 65 is attached to the connecting member 63 through the slot 66 of the mounting piece 67. The cap 65 is fixed by connecting it with a bolt that passes through the cap 65.

For this cap fixing work, the connecting member 2,
A working hole is provided on the upper surface of the cover 17 at 2', and a cover 68 is slidably fitted into the cover 17 in advance, and after the work is done, it is moved forward in the direction of the arrow and is fixed by frictional engagement inside the cap 65. , the working hole is shielded from the outside.

As shown in Fig. 39, the connection process at the ridge of this structure generally follows the above-mentioned mounting procedure, and in this structure, the cover glass frame ridge upper crosspiece 2
2 is connected to the connecting member with bolts 69 as shown in the figure, and the hot water piping section 70 extending in the left-right direction of the roof is connected to the ridge section member 72 having a substantially L-shaped cross section and incorporating the ridge section heat insulation partition member 44 and the heat insulating material 71. Therefore, it is placed in an enclosed space. The drainage wall 6 (FIG. 4) is attached to the ridge side end of the roof main body 10 across the protrusion 13 of the main body 10, and is attached to the inner edge of the inner half of the wall 6 in the vertical direction. Projections 73, 7 protruding together
4 and the inner side of the wall 6 with the metal plate 7 constituting the upper surface of the metal roof being sandwiched between protrusions 75 and 76 which are offset from each other and project from the middle of the outer half of the wall 6. They are tightly connected using bolts 77 that pass through the peripheral walls of the halves. Also, wall 6
A shallow notch 78 is provided in the outer half of the arcuate peripheral wall to further ensure the tightening effect.

In addition, in FIG. 39, those arranged above in the ridge are a conduit 79, a communication pipe 80, and a water sprinkling pipe 81 having a large number of pores, which constitute the elements of the cleaning water sprinkling device of this collector. The supply of cleaning water to the conduit 79 can be carried out, for example, by a water supply pipe that passes longitudinally through the connecting member from the eaves. An embodiment of such a system is shown in FIG. 40, in which 81 and 82 are horizontal and vertical water conduits, respectively, and 83 is a water supply pipe running longitudinally between the vertical walls of the connecting members 2, 2'. Note that FIG. 41 is a partially cutaway view of the upper part of the connecting member to clearly show the state of the piping.

According to the present structure configured as above, the vertical bars of the cover glass frame are fitted into the upward supporting parts formed on the sides of the connecting members arranged in parallel, and solar energy is collected below the glass frame. Since the device is attached, when the cover glass frame is installed on a roof structure, since the invention of the present application has the above configuration, the cover glass frame has vertical bars on both sides, and vertical bars on the top and bottom of the frame. Since the upper and lower crosspieces are attached, the cover glass frame can be engaged and installed without using bolts, nuts, or other tightening members, making installation convenient. There is no need to worry about rainwater draining into the eaves and getting wet. Further, since the engaging groove is provided in the center of the vertical wall of the connecting member and the connecting member is engaged with the engaging groove, the elasticity of the upper portion of the connecting member can be improved. In addition, since the adjustment mounting plate is attached to the lower crosspiece of the cover glass frame, even if the size of the cover glass frame is short, it can be adjusted with the adjustment mounting plate, making it convenient to attach the cover glass frame.
