Abstract

PURPOSE:To enable the constant stable fixation of a solar heat collector which is installed for use on a roof, even when the wind blows up. CONSTITUTION:A hole 9 for providing a connecting device for fitting a fixation wire is made in the end of a fixation-wire fitting arm 6. Numeral 10 denotes the fixation wire. By adopting such a construction, the jointing point of the fixation wire 10 to a supporting frame 2 can be set at a positions as high as required from the floor surface of the supporting frame so that the relation between the strength angle thetaT of the fixation wire 10 and an angle theta of fitting a heat collector is thetaT>theta. When a force FW blowing the collector upward acts with the wind so that it rotates the supporting frame around the supporting point D of the rear leg of the supporting frame, a force FM which acts in parallel to a line connecting the jointing point C of the rear frame member of the frame to the fixation wire with the supporting point D is necessitated on the front frame member side so as to counter the rotation of the frame, and a tensile force F is generated in the fixation wire to meet this necessity. This construction thus secures the stability of the frame, and accordingly it can prevent the heat collector from being unsteady when a strong wind blows, and the consequent damage of the collector and a roof.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an installation mechanism that can always stably fix a solar heat collector installed on a roof, even when the wind blows up. be.

Conventional bridge construction and its problems As a means of installing a solar heat collector on a roof, as shown in Figs. Fix the heater (31), and then install the heat collector (3)
In order to prevent the wires from being blown away by the wind, falling down or falling down during an earthquake, the
and a part of the roof (1).

Generally, the angle θG of the roof is often around 22° to 30°, but the installation angle θ of the heat collector is 30° to improve heat collection efficiency.
It is often set to a higher value. Therefore, when the inclination angle θG of the roof is small and the installation angle 6 of the heat collector is large, the installation angle θ of the heat collector and the tension angle θT of the overhead wire 00) are θT
There may be a relationship of θ.

As shown in Figure 7, when the relationship between θT and θ exists, the heat collector (3
) is blown up from below by the wind, and the force is concentrated when it blows up, and the connection points B and C of the heater (3), the pedestal (if it is larger than the weight of IIJ, the overhead wire uO) and the pedestal (lυ) are easily connected [ The positions of B' and C' were moved, and the stability of the heat collector could not be maintained with the overhead wire (10) alone.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned difficulties and to provide a mechanism that can ensure the stability of a heat collector no matter what state the heat collector is installed in.

Structure of the Invention In order to achieve the above object, the solar coupling device according to the present invention is installed in a structure in which the connection point with the overhead wire can be selected above the floor surface of the trestle, so that the tension angle θ of the overhead wire can be adjusted.
T and the mounting angle θ of the heat collector can be selected so that JT > θ at all times, which reduces the tension acting on the overhead wire and eliminates the risk of the heat collector being uneasy due to wind blowing up like in the past. Qualitativeness can also be resolved.

Description of examples An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

In the figure, (1) is a roof, and (2) is a frame attached to the roof +11 at an angle, on which a heat collector (3) is placed.

(4) is the front frame of the floor portion of the pedestal (2), which is located at a lower position than the rear frame. (5) is the side frame of the frame (2), (6) is the overhead wire attachment arm that stands upright on the corner of the floor of the frame (2), and (7) is fixed to the corner of the floor of the frame (2). It is a reinforcing plate that also serves as a bent leg (8), and is bent along the longitudinal direction as shown in Figure 3, with one bent side serving as the front frame (4) and the other side serving as the side frame (5). At the same time, the overhead wire mounting arm (
6) is fixed. A hole (9) is provided at the tip of the overhead wire attachment arm (6) for providing a connecting device for attachment of the overhead wire. 00) is an overhead wire. Note that similar effects can be obtained even when the rear frame is made lower than the m1 frame.

By adopting such a configuration, the connection point between the overhead wire 00) and the pedestal (2) is aligned with the pedestal floor surface so that the tension angle θT of the overhead wire 10 and the heat collector mounting angle θ are vT>θ. It can be placed as high as necessary to ensure the wind resistance stability of the collector.

That is, as shown in Fig. 4, the force l! is blown upward by the wind on the heat collector. When W acts, the pedestal tries to rotate around the fulcrum of the rear leg of the pedestal. To counter this, a line connecting the direct connection point C between the rear frame and the overhead wire and the fulcrum on the front frame side is used. A force called FM parallel to is required, and a tension of 1' is generated in the overhead wire accordingly. As shown in Fig. 4, when vT becomes large and becomes BT', an anti-rotation force of 1'M' is required, and although this pMt is not much different from FM, it is larger than θT', so F' is It can be seen that it is significantly smaller than F.

Effects of the Invention As described above, the present invention has the above-described configuration, so the mount can be stabilized and the collector can be prevented from shaking during strong winds, and damage to the collector and the roof can be prevented. It can be prevented.

In addition, since the connection point between the trestle and the overhead wire can be selected above the trestle floor surface, vT can be increased, and as a result, the tension acting on the overhead wire can be reduced, so the number of overhead wires can be reduced. It is possible to save money and change to a thinner catenary line.
