Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is related to the improvement of the support device for the heat collection tube in the solar heat collector. This paper proposes a support device that is easy to solve and can be installed on a rooftop or the like and can withstand strong winds.

0002

[Conventional technology]

Conventionally, it has been known to use tubular collectors to collect solar heat (for example, (For example, Utility Model Application No. 50-96247) In addition, a large number of such tubular heat collectors are arranged in parallel. It is also well known to install on rooftops etc.

0003

[Problem that the idea aims to solve]

However, due to its purpose, the above heat collector is not suitable for use on rooftops or other unobstructed areas. It must be installed in a place where there is strong Light weight is preferred. In particular, tubular heat collectors using glass tubes are It has the advantage of being able to freely adjust the installation angle, but the fixed part is circular and weak. Because of this, it is difficult to fix, and there are problems in that it is difficult to maintain strength against wind pressure and the like.

0004

[Means to solve the problem]

This idea can solve the problems mentioned above, and its gist is as follows: The roller has a heat exchange section installed in each of a large number of parallel heat collection tubes, and heat is transferred inside the heat exchange section. It is inserted into a manifold with a flow path for the transfer medium and supported, and the bottom of the heat collection tube is In a solar heat collector in which the part is supported by a support rod installed parallel to the manifold. , hold the bottom of the heat collecting tube with a U-shaped clip, and then attach both legs to the support rod. Insert the two legs through the pair of openings and connect them together on the back side of the support rod. On the other hand, below the manifold and support rod, there is a direction perpendicular to these. A plurality of support rails are provided on the support rail, and the manifold and support rod are attached to the U It is fixed with a letter-shaped fixture.

[0005]

[Effect]

The support device according to this invention is configured as described above, that is, the support device according to the invention is configured as described above. Insert and fix the heat exchanger at the top end into the manifold, and clip the lower end to the support rod. Fix it in a loop shape to form an integral frame, and then fix it to several support rails. In particular, U-shaped clips and U-shaped fixtures are used for fixation. This makes it possible to fix and disassemble with simple operations, and also to remove fixing members such as heat collecting pipes and support rods. Since it is held in place, it does not loosen and can withstand strong winds. The following is based on the drawing. I will explain the idea in detail.

[0006]

【Example】

In Fig. 1, reference numeral 1 indicates a heat collecting tube made of a glass tube with a heat collecting plate sealed inside. Pipe 2 is a manifold with a water pipe for heat transfer inside, and 2a is the water pipe. It is an entrance/exit. The above heat collecting pipe 1 passes through the manifold 2 and connects its top to this water pipe. The heat exchange parts are inserted and connected.

[0007] Next, reference numeral 3 denotes a support rod that fixes the bottom of the heat collection pipe 1. 1 is installed as follows. That is, as shown in Figures 3 and 4, Hold the bottom of the heat tube with a U-shaped clip 4, and attach both legs of the clip 4 to the support rod 3. These tips are connected with a wire 5 after being inserted through the provided through hole. 6 is loose It is made of rubber, and the clip itself is made of a thin spring plate.

[0008] Next, in FIG. 1, reference numeral 7 fixes the support rod 3 and manifold 2. It is a support rail, and several rails are provided in the direction perpendicular to these, and the manifold 2 is , is fixed to this support rail 7 with a U-shaped fixture 8 as shown in FIGS. 5 and 6. There is. That is, the manifold 2 is held from above and its legs 8a are supported. It is inserted into the through hole of the holding rail 7 and fastened with a nut 8b on the back side thereof.

[0009] In addition, the support 3 to which the bottom of the heat collecting pipe 1 is fixed is also a U-shaped fixture as shown in FIG. 9 is fixed to the support rail 7, and in this way, the heat collecting pipe 1 and the manifold The support rail 7 to which the card 2 is fixed is further attached to the support frame 10 as shown in FIG. It is being

0010 This device is constructed as described above, and the top of the heat collecting pipe 1 is connected to the manifold 2. The bottom part is held and supported by a U-shaped clip 4. When the heat collecting pipe 1 is firmly fixed by being fixed to the retaining rod 3 to form a loop, In both cases, the integrally constructed frame is further fixed with several U-shaped fixtures 8. It is fixed and reinforced to the support rail 7, and can withstand strong winds. In addition, it is easy to assemble and disassemble without welding, and it can be installed in high places. It is also very convenient.

[0011]

[Effect of the idea]

As is clear from the above explanation, this idea is a heat collecting device that connects a large number of heat collecting tubes in parallel. In solar heat collectors designed to form a It is constructed in the form of a one-piece frame and can withstand strong winds when installed in high places such as rooftops. At the same time, it is easy to assemble and disassemble, and maintenance is easy, so the practical benefits are It is significant.
