At the same time, the present invention relates to a solar collector fixing device capable of withstanding high wind pressure, which can reduce the number of side bars required for fixing and can fix the collector more simply and quickly.

Solar thermal energy is clean and almost infinitely usable compared to nuclear energy or fossil fuel energy, and there are no problems such as radiation pollution, waste generation, and global warming caused by the use of fossil fuel energy. In this regard, it is very popular in recent years as a very environmentally friendly energy. Such solar energy has been applied to various applications such as hot water hot water supply system, solar cell, solar power generation system using solar heat.

Among them, the solar hot water supply & heating system, which is a kind of solar energy regeneration system using solar heat, transfers the absorbing plate that absorbs the solar radiation heat and the transmission glass and the solar radiation heat that generate the greenhouse effect by preventing the re-reflection of the unabsorbed radiant heat. It includes a solar collector consisting of a main pipe, a branch pipe, which is a transfer path, and transfers solar radiation heat generated from the collector to a heat exchanger to heat the heat storage tank. In addition to the collector, the solar hot water supply & heating system includes a plate heat exchanger, an expansion tank, a circulation pump, a heat storage tank, and a solar controller depending on the purpose.

Such solar collectors are often installed on flat lands, but are often installed in places such as building roofs or rooftops where sunlight is well received and less affected by shielding by other buildings.

1 is a schematic perspective view showing that a solar collector is installed on a mounting stand by a conventional fixing device, and FIG. 2 is a side view thereof.

For reference, other device configurations (eg, heat exchangers, circulation pumps, etc.) of the solar energy regeneration system connected to the solar collector are not directly related to the present invention, and thus the drawings are omitted in the accompanying drawings.

As shown in Figure 1 and 2, the solar collector (2) is arranged at regular intervals along a plurality of horizontal bars (3) arranged in parallel at a predetermined interval on the mounting surface of the mounting stand (1). Both ends of the collector 2 are respectively extended to two adjacent side bars 3, and the two sides of the collector 2 are joined to each other by means of a fixing clamp as a fixing device. It is fixed to 3). The fixed clamp is coupled to wrap around the lower edge of the side end of the collector (2), the lower clamp (4) is fastened by the fastening member to the side bar (3), the upper edge of the collector (2) It consists of the sub clamp 5. At one end of the upper clamp 5 and the lower clamp 4, bent portions having fastening holes are formed, respectively.

Third, because the collector to be installed by filling all the clamps for each collector on the side bar (3), there is a problem that the installation work is cumbersome, the installation time takes a lot, and workability in the field is significantly reduced.

Fourth, the larger the number of horizontal bars (3) to be installed on the mounting stand 1, the larger the space required for installation between the side bars (3), the larger the area of the mounting stand (1) corresponding to the mounting intervals Further, the installation area of the collector is reduced by the space required for fastening the fastening member, so that the number of collectors that can be installed on the mounting surface of the mounting stand 1 is reduced, so that the space utilization of the mounting stand 1 is lowered. Its disadvantage is that it doesn't look good either.

The present invention has been made in order to solve the above problems, the object of the present invention is to provide a solar collector fixing device that can withstand high wind pressure that can be connected to the solar collectors connected to each other and can be fixed on the horizontal bar. do.

However, the present invention is not limited to the scope of the following examples, and various modifications are possible within the scope of the technical idea of the present invention described in the claims.

Figure 3 is a schematic side view showing the configuration of a solar collector fixing device capable of withstanding high wind pressure of an embodiment of the present invention, Figure 4 is a plan view and a side view of the upper fixed clamp 20, the lower fixed clamp shown in FIG. And a schematic diagram of the fastening member.

3 and 4, the fixing device of the embodiment according to the present invention, the lower fixing clamp 10 is fixed to the horizontal bar (3), and the upper fixing clamp 20 is coupled to the upper portion of the lower fixing clamp (10) ) And a fastening member for fastening the upper and lower fixing clamps (20, 10).

The lower fixing clamp 10 includes a base plate 11 and a protrusion coupling portion 12 protruding from the base plate 11 and having a width smaller than that of the base plate.

Base plate 11 is a portion that is coupled to the side bar (3) of the mounting stand 1 and can be coupled to the side bar (3) by a separate fastening member like a conventional fixing device. However, as in the present embodiment, the bent portion 13 bent to surround the side and the bottom of the horizontal bar (3) protrudingly formed in the lower base plate, the inner surface and the base plate 11 of the bent portion (13) By fitting the horizontal bar (3) between the lower surface, there is no need for a separate fastening member and fastening work, there is an advantage that can be easily fixed to the lower fixing clamp (10). The height of the bent portion 13 from the bottom of the base plate is slightly smaller than the side height of the side bar 3 so as to force the side bar 3 into the bent portion 13. Grooves 14 for rainwater discharge are formed on the upper surface of the base plate at both sides of the protrusion coupling part 11.

The protrusion coupling portion 12 is formed to protrude from the center of the base plate 11, both sides of the protrusion coupling portion 12 is located at the same distance from both ends of the base plate. At the time of coupling the solar collector 2, the sides of the solar collector 2 are located on both sides of the protrusion coupling part 12, and both upper surfaces of the base plate 11 extending from both sides of the protrusion coupling part 12. The lower portion of the solar collector (2) is located, so that both sides of the projecting coupling portion 12 and the upper surface of both sides of the base plate 11 is coupled surface portion of the shape surrounding the lower edge of one side of the solar collector (2) do. Since the adjacent solar collectors 2 are respectively coupled to both sides of the protrusion coupling portions with the protrusion coupling portions 12 interposed therebetween, the width of the protrusion coupling portions 12 is equal to the set interval required between the solar collectors 2. It needs to be formed. Since the upper fixing clamp 20 is coupled from the upper portion of the lower fixing clamp 10, the upper surface of the protruding coupling portion 12 is a coupling surface for the upper fixing clamp 20, the fastening member ( A fastening hole 12a into which 30 is inserted is formed. Preferably, the fastening hole 12a may be formed to extend into the protrusion coupling part to be a fastening groove 12b. With this configuration, when the bolt 31 as a fastening member can be inserted into the fastening groove 12b at the time of fastening, when the nut 32 is fastened to the bolt 31 by tightening for fastening, Since the bottom of the fastening groove 12b can support the bolt head, not only the fastening work can be facilitated, but also the nut 32 can be tightened more firmly, thereby providing a stronger fastening force to the upper and lower fixing clamps 20 and 10. There is an advantage to this. A weight loss part is formed between the protrusion coupling part 12 and the base plate 11, thereby reducing the weight of the lower fixing clamp 10. The shape of the weight portion, as shown in Figure 3, but may be a form in which both the space between the protrusion coupling portion 12 and the base plate 11 is empty, as shown in Figure 6 to be described later, protrusion coupling It is also possible to have a form in which both sides are emptied except for the lower part of the part in which the negative fastening groove 12b is formed. The former slimming part has an advantage of further reducing the weight of the lower fixing clamp 10, and the latter form has an advantage of reinforcing the supporting force of the fastening member 30 inserted into the fastening groove 12b. There is this.

The upper fixing clamp 20 may include a protrusion coupling plate 22 protruding in a direction opposite to the protrusion coupling portion 12 of the lower fixing clamp 10, and a base plate extending from both ends of the protrusion coupling plate. 21). The width of the base plate 21 and the protruding coupling plate 22 of the upper fixed clamp 20 is not particularly limited, but the base plate 11 and the protruding coupling portion of the lower fixed clamp 10 to be correspondingly coupled thereto. It is preferable to form the same as the width of (12). In addition, the height of the protrusion of the protrusion coupling plate 22 of the upper fixing clamp 20 and the height of the protrusion of the protrusion coupling portion 12 of the lower fixing clamp 10, so that a strong clamp force can be applied between the upper and lower fixing clamp, It is necessary to set such that the engaging surfaces of the projecting engaging portion 12 and the projecting engaging plate 22 are in close contact with each other when the fixing clamp is fastened. In addition, if the protrusion height of the protrusion coupling portion 12 and the protrusion coupling plate 22 is too different, the coupling member 30 which is positioned on the coupling surface of the protrusion coupling portion and the protrusion coupling plate at the time of fastening is the top or the like. Since it is excessively biased toward either side of the lower part, the protruding height of the protruding coupling part 12 and the protruding coupling plate 22 is set so that the position of the fastening member 30 at the time of fastening is located in the middle of the upper and lower fixing clamps as much as possible. It is desirable to.

Engaging projections 21a are formed at both ends of the base plate 21 of the upper fixing clamp 20, and the engaging projections 21a are engaged with the stepped portions of the frame of the solar heat collector 2. It is possible to secure the collector 2 more securely.

The distance between both ends of the protruding coupling plate 22 of the upper fixing clamp 20 and both ends of the base plate 21 extending therefrom is the same. When the solar collector 2 is coupled, both sides of the solar collector 2 are located on both sides of the protruding coupling plate 22, and both lower surfaces of the base plate 21 extending from both sides of the protruding coupling plate 22. The upper portion of the solar collector (2) is located, so that the mating surface portion of the both sides of the protruding coupling plate 22 and the lower side of both sides of the base plate 21 surrounds the upper edge of one side of the solar collector (2) do. The lower surface of the protruding coupling plate 22 becomes a coupling surface with respect to the lower fixing clamp 10, and a coupling hole 22a into which the coupling member is inserted is formed.

The type of the fastening member 30 for fastening the upper and lower fixing clamps is not particularly limited. For example, bolts 31, nuts 32, etc., as shown, may be used. Of course it can be used.

FIG. 5 is a schematic side view illustrating a process of installing the collector 2 on the side bar 3 using the fixing device of the solar collector 2 of the embodiment of FIG. 3.

First, the horizontal bar 3 is inserted between the lower surface and the bent portion of the lower fixing clamp 10 to fix the lower fixing clamp 10 to one side of the horizontal bar 3 (FIG. 5 (a)).

Next, the opposite sides of the two collectors 2 adjacent to the engaging surface portion of the lower fixing clamp 10 are positioned, and the upper fixing clamp 20 is positioned at the upper and lower fixing clamps 10 of the opposite sides of the collector 2. ) And placed on () (FIG. 5B).

Thereafter, the fixing bolt 31 is fastened to the fastening hole (22a) formed in the projecting coupling plate 22 of the upper fixed clamp 20 and the fastening hole (12a) formed in the projecting coupling portion 12 of the lower fixed clamp (10) and Inserted into the fastening groove (12b) is extended and pushed to the bottom of the fastening groove, and then tighten the nut 32 to the bolt 31 from the upper surface of the protruding coupling plate 22 to complete the fastening operation ( 5 (c)).

6 is a schematic side view showing a state in which the installation of the collector 2 is completed by the fixing device of the present invention. As described above, between the protrusion coupling portion 12 and the base plate 11 of the lower fixing clamp 10 shown in FIG. 6, the lower portion of the portion where the coupling groove 12b of the protrusion coupling portion 12 is formed is formed. Excluding both sides of the hollow portion is formed, the weight is reduced, thereby reducing the weight of the lower fixing clamp 10, and at the same time to strengthen the bearing capacity of the fastening member 30 inserted into the fastening groove.

As shown in Figure 6, the fixing device of the present invention, unlike the conventional collector (2) fixing device in which the collector (2) is coupled to only one side of the upper and lower clamps, the solar collector (2) on both sides of the upper and lower fixing clamp It is characterized in that it has a coupling surface portion to be coupled. In such a support structure, since the collectors 2 adjacent to each other are connected to each other through upper and lower fixing clamps, it is possible to form a collector structure that is more robust and durable.

Solar collector (2), the nature of the collector (2) should be located at the top of the building. This is where wind pressure is most directly affected. Therefore, the solar collector 2 should be designed to withstand the high wind pressure of the mounting stand 1 to which the collector 2 is fixed, and to be fixed to the bottom of the mounting stand 1, The high accuracy of the collector (2) on the mounting surface of 1) is to be designed in consideration of these high wind pressure conditions. According to the present invention, since the collectors 2 form a rigid support structure that is interconnected with each other, durability against high wind pressure becomes very good.

In addition, as shown in Figure 6, as the collector 2 is attached to both sides of the upper and lower fixing clamps, when the lower fixing clamp 10 is installed on one side bar (3) to one side bar (3) Since one end portion of two adjacent collectors 2 can be naturally stretched and installed, the number of side bars 3 required as compared with the conventional fixing device can be greatly reduced.

On the other hand, the conventional fixing device has a structure in which the collectors 2 are respectively coupled to upper and lower clamps provided on separate horizontal bars 3, so that the number of the horizontal bars 3 provided between the adjacent collectors 2 is higher than that of the present invention. I needed a lot. Referring to FIG. 1, the conventional fixing device has a structure in which the fastening members 6 are fastened to the bent portions formed at one end portions of the upper and lower clamps 3 and 4, respectively. The pair of left and right upper and lower clamps opposed to each other on the side bars 3 of the pairs could not be located together. In addition, separate coupling members are required for coupling the left and right upper and lower clamps facing each other, resulting in fastening operation and cost increase. On the contrary, in the present invention, since the collectors 2 are simultaneously connected to both sides of the upper and lower fixing clamps 20 and 10, and only one fastening member is fastened to the center of the upper and lower fixing clamps, the lower fixing clamp 10 is fixed. It is sufficient that only the space in which is to be located (that is, the space on one side bar 3) is reduced, and the number of members and the working time required for fastening are much reduced.

In the mounting stand 1 shown in FIGS. 1, 2 and 6, only two rows of two collectors are arranged along the installation surface, but the number of stages of the collectors 2 is within the design limit. Can be increased. In the conventional fixing device, since two horizontal bars 3 are required for one collector 2, the number of side bars 3 installed on the mounting stand 1 increases as the number of steps increases (for example, 2 n horizontal bars (3) are required when the singular is n). However, the present invention, since the adjacent collector 2 is fixed across one side bar (3), n + one side bar (3) is required when the n-stage collector (2) is installed, the required side bar ( The number of 3) will be drastically reduced.

In addition, as the number of the side bars 3 decreases, the area occupied by the side bars 3 and the area between the side bars 3 on the installation surface is reduced, so that the collector 2 can be installed more densely and more. Its space utilization is improved and its installation appearance is also improved.

In the installation of the collector 2, two collectors 2 adjacent to the left and right sides of the lower fixing clamp 10 can be placed at the same time and installed by one fastening between the upper and lower fixing clamps. I can make it simple.
