Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for supporting a solar water heater outdoors.

Solar water heaters have the highest heat absorption efficiency when sunlight is irradiated at right angles to the water heater. However, the support devices for conventional solar water heaters (hereinafter simply referred to as water heaters) have been fixed, so even if the water heater is installed at an angle so that the sun's rays are irradiated almost at right angles to the water heater,
As the sun moves, the angle at which the water heater is irradiated changes and the irradiation comes from an oblique direction, which has the disadvantage of reducing the efficiency of solar heat absorption. Therefore, the amount of time the sun's rays are irradiated at right angles is shortened, and thermal energy cannot be used effectively, resulting in better water heating effects.

The present invention eliminates the conventional drawbacks in support devices for solar water heaters, and provides a solar water heater support device that can hold the water heater in a state where sunlight is irradiated almost at right angles for a long period of time. The object of this invention is that the inclination angle of the support frame that supports the water heater can be changed.

Next, one embodiment of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes an underframe formed in the shape of a rectangular frame from a shaped steel material, and substantially mountain-shaped base pieces 2, 2 are fixed to the outer sides of both left and right ends on one side of the underframe. Reference numeral 3 is a vertical frame formed into a rectangular frame shape using a separate shaped steel material, and reinforcing members 4 made of band-shaped flat iron plates crossed in an X shape are fixed to the upper and lower parts of the back side of the vertical frame. The lower left and right ends of the vertical frame 3 are inserted between the left and right base pieces 2, 2 of the underframe 1, and are pivoted 5 so as to be rotatable. The left and right vertical bars 6, 6 of the vertical frame 3 are provided with shaped steel having a U-shaped cross section facing inward, and are provided with a number of holes for inserting locking pins at appropriate intervals in the vertical direction. 7 is installed through the front and rear direction. Further, one end of the upper horizontal rod 8 projects slightly outward from the end of the vertical rod 6.

Reference numeral 9 denotes a support frame formed in the shape of a rectangular frame from shaped steel material, which supports the solar water heater. A reinforcing member 11 is provided in which the shaped steel material is extended in the longitudinal and lateral directions. The outer dimensions of the support frame 9 are formed to be slightly smaller than the inner dimensions of the vertical frame 3, and the lower left and right ends of the support frame 9 are vertically hung on the left and right sides above the horizontal rods 12 at the bottom of the vertical frame 3. It is inserted between the upright pieces 13, 13 and rotatably pivoted. Further, both ends of the upper horizontal bar 10 are inserted inside the U-shaped cross section of the left and right vertical bars 6, 6 of the vertical frame 3, as shown in Fig. 4, and can be moved up and down inside. There is.

Reference numeral 14 denotes a winder which can be rotated by being fitted onto a supporting shaft 15 which is fixed and protrudes in the lower part of the vertical rod 6 in the horizontal direction on the side where the horizontal rod 8 at the upper part of the vertical frame 3 projects outward. It is a cylinder with several grip sticks 1 at its outer end.
A handle ring 17 having 6 radially arranged thereon is fixed.

Pulleys 18 and 19 are rotatably provided at the top of the support frame 9 near both left and right ends of the horizontal bar 10, and pulleys 18 and 19 are rotatably provided near the insides of the left and right vertical bars 6 and 6 of the vertical frame 3. Pulleys 20 and 21 are installed at the bottom of the horizontal rod 8.
is rotatably provided, and a pulley 22 is also rotatably provided below the portion where the horizontal rod 8 projects outward from the vertical rod 6. In FIGS. 2 and 4, 23 is a wire rope with one end fixed to the lower left part of the horizontal rod 8, and is connected to the pulley 1 of the horizontal rod 10.
8 and the pulley 20 on the upper part of the rope, it is pulled to the right, then the pulley 22 on the right end is suspended, and the other end of the rope is wound around the winding tube 14 an appropriate number of times. It is fixed to the winding tube. Another wire rope 24 has one end fixed to the lower right part of the horizontal rod 8, and then connects to the pulley 19 of the horizontal rod 10 and the pulley 2 above it.
1, and is further hung around a pulley 22 at the right end to reach the lower part, and the other end of the rope is wound around a winding tube 14 an appropriate number of times and then fixed to the winding tube 14. 2
5 is a solar water heater supported and fixed on a support frame 9.

As shown in FIG. 1, the solar water heater support device of this example is used by placing and fixing the water heater 25 on the support frame 9, and placing the device at an appropriate location such as on the ground or on the roof of a building. It is something. When changing the inclination angle of the support frame 9 that supports the water heater 25 according to the irradiation angle of the sun, it can be done by rotating the handle wheel 17. That is, as shown in FIG. 1, when the grip bar 16 of the handle ring 17 is rotated in the direction to unwind the rope, the upper part of the support frame 9 is lowered by the amount that the rope is unwound, and the angle of inclination changes. In this case, since the two ropes are unwound by the same length, the horizontal bar 10 of the support frame 9 descends while maintaining its horizontal state. A locking pin (not shown) is inserted into a hole 7 provided in the vertical rod 6 at an appropriate angle of inclination to receive and lock the horizontal bar 10 at the top of the support frame 9. By increasing the number of pin insertion holes 7, the inclination angle can be finely adjusted.

Further, by rotating the handle ring 17 in the opposite direction, the wire rope can be wound up to raise the upper part of the support frame 9, and the support frame 9 can be positioned at an appropriate inclination angle. When the upper part of the support frame 9 is raised and lowered, both ends of the horizontal bar 10 move up and down within the U-shaped grooves of the vertical bars 6, and do not come off. It rotates back and forth around the pivot point at the bottom end.

In this way, the angle of the support frame 9 can be changed at appropriate intervals so that the sunlight always irradiates the water heater 25 at a substantially right angle, and the absorption efficiency of solar heat can be extremely improved.

Furthermore, since the support device of this example has a lightweight structure, when moving the installation location, it can be easily moved as is.
By removing the bolts at the lower part of the frame or the pivot points at the lower part of the support frame 9, it can be folded, making it even easier to carry.

Note that when using a large water heater, etc., it is possible to rotate the winding cylinder 14 by a motor, but in the case of a small water heater, it is more appropriate to use a hand-cranked system to reduce manufacturing costs. .

As described above, in the present invention, the angle of inclination of the support frame that supports the solar water heater can be freely changed by rotating the handle wheel, so that the angle of sunlight irradiating the water heater is always approximately at right angles. It has the advantage of being able to maintain high heat absorption efficiency at all times, resulting in a good water heating effect and the ability to effectively utilize solar thermal energy.

Further, the present invention has a simple structure, is easy to operate, and has a lightweight structure and is foldable, so it can be easily moved from one place to another.
