Description

[Detailed description of the invention] (a) Industrial application field The present invention is an improvement of a solar heat collector housing fixing device that is capable of arranging and fixing multiple solar heat collector housings on a mounting plate. Regarding.

(b) Background Art Conventionally, when a plurality of housings containing built-in solar heat collectors are fixed on a mounting plate installed on the roof of a building, etc., as shown in Japanese Utility Model Publication No. 35-29078, for example, In addition, since the mounting part with the screw hole protruding from the side surface of the end of the housing is screwed to the mounting plate, when multiple solar heat collector housings are installed in parallel, There was a drawback that the mounting portions protruding from the side surfaces of the ends of the body were a hindrance, making it impossible to juxtapose them sufficiently close to each other.

In addition, in order to reduce the mounting area of the solar heat collectors while arranging them closely together, it is best to make the mounting part of the heat collector case as hidden from the surface as possible. It's difficult to get rid of. for example,
Although it is sufficient to provide a recess at the corner, consideration must be given to the formation of the recess so as not to reduce the heat collection area of the heat collector itself.

By the way, it is necessary to store connecting pipes, heat insulating material, etc. together with the solar heat collector inside the casing, and the recess inevitably cannot secure enough space for fixing the casing. Such a narrow recess does not provide sufficient work space, and tools such as a box screwdriver (wrench) cannot be used for screwing, making it difficult to perform simple and strong installation work.

(c) Purpose of the invention The present invention has been made in view of the above-mentioned facts, and is a solar heat collector housing of a type in which a plurality of solar heat collector housings are arranged and fixed in parallel on a mounting plate. The fixing device utilizes a small amount of dead space on both sides of the end of the casing, which not only reduces the mounting area of the casing, but also makes fixing the casing a simple task.
Moreover, the aim is to ensure that it is carried out firmly.

(d) Key points of the invention The present invention provides a pair of recesses in which the end corners of the solar heat collector housing are recessed inward, and a mounting board for the housing is placed in each of these pair of recesses. At the same time, the mounting board is provided with a notch for screwing.
In addition, in the case where a plurality of solar heat collector casings are arranged and fixed on the mounting plate by tightening and fixing these mounting boards on the mounting plate with screws through these notches, this mounting board has , a notch is provided at a position where a long hole is formed when the solar heat collector housings are juxtaposed and the screw fixing notches of the mounting board are adjacent to each other, and the notch has a length that covers the notch, and the notch has a length that covers the notch. It is characterized in that a mounting washer having a hole for inserting a screw is interposed in the inner portion thereof, and the screw is passed through the notch so that the mounting board is tightened and fixed to the mounting plate.

(E) Example of the invention An example of the invention shown in the drawings will be described below. In Fig. 1, 1 is a solar heat collector housing, and inside the housing 1, a plurality of vacuum tube type solar heat collector tubes 2, 2... are arranged between a pair of frames 3, 3'. It is stored as set up. These solar heat collecting pipes 2, 2... communicate in series within the above-mentioned frames 3, 3', and one frame 3 has a liquid inlet pipe connected to these solar heat collecting pipes 2, 2... 4 and a liquid outlet pipe 5, heating liquid such as water is introduced from the liquid inlet pipe 4 to a plurality of solar heat collecting pipes 2, 2... connected in series, and the heat collecting pipes 2 , 2 . . . after being heated by sunlight, the liquid is discharged from the drain pipe 5. The casing 1 is provided with a pair of recesses 6, 6, which are formed by recessing inward into the casing, on the end side surfaces thereof, and the bottom plate of the casing 1 is inserted into the recesses 6.
A mounting board 7 is provided to protrude inwardly, and an elongated screw notch 8 is bored in the mounting board 7 from the end face toward the center of the board.

FIGS. 2 and 3 show an installation example in which the solar heat collector casings 1 and 1 described above are arranged side by side and placed on a mounting plate 9. Reference numeral 10 denotes a mounting washer that straddles a pair of adjacent mounting boards 7, 7 and fixes these boards at the same time;
Reference numeral 1 denotes a tightening screw, and the two housings 1, 1 are placed close to the mounting plate 9 so that the open end surfaces 12, 12 between the screw fixing notches 8, 8 of the mounting substrates 7, 7 face each other. At the same time, cover the mounting boards 7, 7 with the end face of the mounting washer 10, insert the tightening screw 11 into the shaft support hole 13 of the mounting washer 10, and pass through the screw fixing notches 8, 8 of the mounting board. It is designed to be fastened and fixed to the mounting plate 9 at the same time.

(f) Effects of the invention As explained above, the solar heat collector housing fixing device of the present invention has a structure in which when a plurality of solar heat collector housings are lined up and fixed on a mounting plate, A pair of recesses are provided with the end corners recessed inward,
A mounting board for the housing is provided in each of the recesses,
An elongated screw-shaped notch for screw fixing is bored in the mounting board at a position where the opening of this notch and the opening of the notch of the mounting board in the adjacent housing recess form one hole. Then, the casings are arranged close to each other so that the screw fixing notches of such a mounting board are close to each other,
By tightening and fixing both mounting boards to the above-mentioned mounting plate with a single screw via the mounting washer that spans both mounting boards, the mounting part of the casing to the mounting plate can be attached to the end surface of the casing. Therefore, multiple solar heat collector casings can be placed closer together on both the left and right sides, compared to a case where the mounting part of the solar heat collector casing protrudes from the casing. This allows a larger number of casings to be placed in parallel on both sides of the mounting plate, allowing for a larger area for solar heat collection. Furthermore, according to the present invention, when installing two solar heat collector casings, a pair of mounting boards are simultaneously fixed on the mounting plate using mounting washers, and this fixing is done using a single screw. This can be done by simply tightening the screws through the notches of the mounting board, and therefore the installation workability is good, and therefore it can be safely mounted even in dangerous places such as the roof of a building. In addition, the screw tightening work for this installation is done in the middle of the mounting boards of adjacent cases, and the area twice the recess can be used as a work space, so there is less dead space in the case, and if only one recess is used, the box cannot be installed. Even if you cannot use tools such as screwdrivers, you can use them.
It can be firmly fixed using screws such as bolts. Furthermore, since the notches for screwing in the mounting board of this proposal are in the form of long holes, it is possible to adjust the juxtaposition gap between two adjacent solar heat collector casings, and when replacing the casing due to damage etc. Simply loosen the screws fixing the mounting board and move the casing in the direction of the long hole in the screw fixing notch to disengage the board and the mounting washer, so only the solar collector casing needs to be replaced. This has effects such as being able to easily remove the solar heat collector casing and easily fixing a new solar heat collector casing to be replaced. In addition, since the mounting portion does not protrude from the housing, packaging of the housing becomes easier, transportation costs can be reduced, and the appearance is not spoiled, providing excellent practical effects.
