Solar collectors with known parabolic reflectors have high temperature collection but have high convective and radiant heat losses in the collector (eg solar cookers), while linear parabolic collectors use vacuum tubes but are concentric glass. It is possible to maintain high vacuum because the distance between wall and collector wall is small, and it is difficult to close airtight by heterogeneous combination of glass and metal, and there was a lot of vacuum breakage due to thermal expansion and contraction during long-term operation.

From an optical point of view, there was light that was reflected back to the outside due to spherical aberration and tracking error at the outer periphery of the reflector, even though it was manufactured precisely with proper RIM angle and condensing ratio, and a casein-type condenser was introduced in various literatures. The secondary reflector, which receives the focal spot and reflects it to the heat collector, should reflect the received light to 100%. However, some light is absorbed as heat and heated to high temperature, resulting in a large loss of incident light.

In addition, the use of the conventional collector was inefficient as a separate device completely separated for heating medium heat production and midstream pure water production, in the present invention is characterized by having two functions as one device.

The present invention is to produce both the heat collecting medium and the distilled pure water while reducing the heat collection heat loss and optical photovoltaic loss pointed out as described above, according to the accompanying drawings, there is a screw portion for fastening in the upper portion and a vacuum forming hole on both sides of the body ( 14-1) and a parabolic with an angle member casing rim 6 formed on the outer circumference of the support rod 14 having a vacuum forming mechanism formed with a conical toilet seat of the airtight ball 20 and a through-hole for mounting the compression spring 19. The hollow ring (9) is joined to the picking ring (15) in the center of the casing (3) by a nut (16) at the lower end of the supporting rod (14), and threaded outwardly on both sides of the center line of the casing rim (6). The parabolic reflector 2 is attached to the inner surface of the casing, and a screw-fastening screw part and a hole for pipe construction are machined under the ash cone. Support Rod (14) The heat medium inlet side pipe 4 penetrates through the rib 9 and attaches white (4-1FIN) at the inner rim of the rim 6 (the outer circumference of the parabolic collector), and the other end of the bottom of the heat collecting body 10 at the other end. Connected to and supported by the support 29 as a preheat collector, a pipe drawn out from the top of the house advertisement heat collector 10 to the third rib 9 is formed as a heat medium outlet side. (10) A bushing (13) made of a heat-resistant material on the upper part and a heat insulating film (11) and a reflector (12) on the outside are covered with a solid shape, and the U-shaped packing ring (7) is formed on the outer circumference of the parabolic permeable body (1). And the packing ring 15 is placed on the rim (6) surface and fastened to the upper part of the heat collecting body 10 with the bolt 16, and the casing 3 and the permeable body 1 At the junction and the circumference, the angle band (5) is wrapped around the material and tensioned with the fastener (5-1) to assemble the whole into a convex lens shape. The packing material 8 is filled around the ifes 4 and 22, and the packing press 8-1 is used to seal the screwed heat pipe at the end of the rib 9 at the end of the rib 9 and insert the ball 20 into the support rod 14. When the vacuum pump is operated by assembling the intake pipe unit of the vacuum pump to the protruding screw portion of the support rod 14, the internal space air on the lens is discharged to a vacuum, and the ball 20 adheres closely to the conical toilet seat. Since the cap (17) is fastened to the place where the vacuum pump piping unit was assembled with the spring (19) inserted and compressed, the cover (18) was put on the upper and lower screw joints, and together with the angle band (5) material surroundings The airtight caulking 21 was used as the collector body.

Thrust bearing (23-1) and journal bearing (23) on the inlet side ribs (9) are assembled to the short support column (25) and journal bearing (23) on the heat medium outlet side (9). 25) assembled to the base 27, and the collector body is rotated in an inclined state, the base frame (28) front end is composed of the pivot joint in front of the base frame (28), and jackscrew-shaped height adjustment (39) from the rear side The height was adjusted so that the collector body tracked the sun.

The motor 30 that can be rotated forward and backward on the base 27 plate is geared and geared down to transfer power to the lead or bent axis 33 on the support support 36. The lead is guided by the guide shaft 35. The collector fork 34, which is moved along the screw shaft 33, is sandwiched between the two ribs 9 between the casings 3 and the clouding rod 24 bent, so that the collector body rotates during the light receiving time from sunrise to sunset. (The angle from "A" to "B" in Figure 3) while tracking the sun, the motor drive signal is not shown in the drawing, but the motor drive signal is a 24 hour timer switch operating time (day) and stop time ( Night), and set the time zone for a certain period of time in the operating time zone, time stop (pause period) operation control to continue the movement and stop the minute distance during the day and position detection switch (40) on one side support support (36) just before sunset Motor 30 when the carrier fork 34 reaches As the direction of rotation changes when reduced to Sunrise operation is the beginning of a myeongil Kane off all power except the 24 hour timer is still one day be released from the same track movement.

As described above, the collector body can also track the year-round sun height with the manual height adjusting device 27, and the solar body can be tracked during the day by the intermittent movement of the timer-operated motor. Therefore, the inlet pipe 4 is a supply water pipe line, the outlet pipe 22 is a storage tank (41, heat storage tank or hot water tank) with a flash fire hose (47) piping configuration, natural convection circulation or forced to the pump It is circulated to supply, heat and store the heat medium.

A plurality of heavy-duty discharge holes 43-1 are formed in the head by extending openings that can be flanged to an upper center of the tank 41, and a funnel-type sump 43 connected to the distilled water (PW) withdrawal pipe 44 at the bottom thereof. ) The same float (45 FLOAT) of the same shape through which the central axis hole is penetrated is connected to the lower part of the tank, and the lower portion of the Hurenji is blocked by the tank 41. The flange of the tank 41, the steam in the tank 41 passes through the steam discharge hole (43-1) of the upper portion of the sump, the distilled water condensed by the heat exchange cooling with the supply cold water in the coil 48 condensed Since it is collected at (43) and descends along the withdrawal pipe (44), the distilled water generator was used to collect and use in a separate sump.

When pure water is required, the valve on the withdrawal pipe 44 may be opened and used. When not necessary, the float 45 may rise due to the generated distilled water buoyancy in the sump 43 to discharge the steam to the cooling coil. It is blocked and stored as a heat source in the tank.

6 is a vacuum state sensor device installed inside the assembly body of the collector, and puts a small amount of colored fluid 53 into a graduated transparent cylinder 50 and sets the position under atmospheric pressure with a hermetic piston 51 loaded therein. Attached to the support rod 14 and the collector body is in a vacuum state, the piston 51 position is higher than the initial position, and the colored fluid 53 space is increased in volume so that the final position is determined at the vacuum degree set in the collector. During operation, the degree of vacuum breakdown inside the collector is visually detected by the piston position, that is, the reduction of the colored fluid space volume, so that the collector body can be checked for vacuum breakdown.

Since the outer circumferential ray of the ordinary parabolic reflector is hard to be collected at the focus of the heat collector (spherical aberration), the solar light outside the reflector 2 region is composed of a coil (4) having a white (4-1) pipe on the water supply side. After the preheating of the heat medium in the form of a flat plate collector, the reflected light of the reflector 2 is focused at the bottom of the focused high temperature collector 10 so that the heat medium is heated to a high temperature, and the heating rod is heated to a high temperature. ) And the heat-resistant bushing 13 is fastened up and down in the casing (3) and the transparent transparent body (10) to serve as a central boogie, so that even if the interior is in a vacuum state can be structurally stable.

The externally drawn reflector 2-1 has an outlet pipe pipe 22 that is always at a high temperature, so that the radiant heat loss is large, so that the additional reflector 2-1 is additionally collected to compensate for the heat loss.

Since the outer side of the heat collector 10 has a large radiant heat loss, the reflective light of the surface reflector 12 acts on the preheater as shown in FIG. will be.

Since the inside of the collector body is usually vacuum, the surface of the collector or reflector 2 does not come into contact with air, so no damage, contamination and freezing occur, and the light collector 10 of the central part heated to a high temperature has a boundary wall in contact with external air ( 1,3) Because the distance from the member to play a long distance, it may be a lower vacuum than known vacuum tube heat collecting tube.

8 is a diagram illustrating a method of installing a plurality of apparatuses of the present invention. In the left-side series installation method, the initial collector outlet pipe is sequentially connected to the next collector inlet pipe, and a high temperature medium is required. Multiple collectors in the inlet and outlet pipes resulted in increased military production.

Solar collectors are installed outdoors, while resisting the long-term resistance to strong winds, tracking requires a small force, the collector body of the present invention is a convex lens shape, the wind resistance is less than any heat collector, the shape is rotated Since the upper and lower weight balances can be easily adjusted with respect to the center axis of the support shaft, the moving force is consumed.
