Description

Technical Field

[0001] This utility model relates to the field of solar thermal collection technology, and in particular to a solar indoor and outdoor concentrating solar collector. Background Technology

[0002] Solar energy, as a clean energy source, is finding increasingly wider applications. With growing environmental awareness, solar energy is being used more frequently in daily life, such as in solar cookers, which are gradually replacing traditional stoves. However, current solar cookers typically use short-focal-length concave mirrors to reflect sunlight for cooking and boiling water. Because of the short focal length of the concave mirrors, the cookware used on these solar cookers is very close to the cooker, usually placed on top of it. Furthermore, solar cookers can only be used outdoors in full sunlight, requiring users to operate the cookware under high temperatures and direct sunlight, creating a harsh environment that can lead to heatstroke, especially in summer.

[0003] A portable solar cooker, as disclosed in patent CN220728556U, includes a concentrating plate for focusing sunlight, a cookware rack movably connected to the concentrating plate, and a support angle adjustment device for supporting and adjusting the pitch angle of the concentrating plate. The concentrating plate is foldable; when the solar cooker is not in use, the cookware is removed, and the concentrating plate is folded inward by rotating two sub-plates, thus folding the cookware rack between the two sub-plates, making the solar cooker easy to carry. However, the cookware needs to be placed on the solar cooker's support, requiring the user to operate and use the cookware outdoors in high temperatures and direct sunlight, resulting in a harsh operating environment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a solar indoor and outdoor concentrating collector to solve the problem that current solar cookers can only be used outdoors, and the environment is harsh when operating the cooker.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An indoor / outdoor solar concentrator includes a chassis. A first support rod and a reflector are connected sequentially from bottom to top on the chassis. A second support rod and a concentrator are connected sequentially from bottom to top on the chassis next to the first support rod. Sunlight shines on the concentrator, is focused by the concentrator, and then shines on the reflector. After being reflected by the reflector, the sunlight passes through an opening in the room and is focused onto a heating container inside the room.

[0007] Furthermore, the condenser lens is covered by a frame, the frame is fixedly connected to the condenser lens, and the condenser lens is rotatably connected to the second support rod.

[0008] Furthermore, the frame includes an inner ring and an outer ring that are sequentially fitted around the condenser lens. The condenser lens is fixedly connected to the inner ring, the inner ring and the outer ring are rotatably connected, and the outer ring is rotatably connected to the second support rod. The axis of rotation between the inner ring and the outer ring is perpendicular to the axis of rotation between the outer ring and the second support rod.

[0009] Furthermore, one end of the second support rod is rotatably connected to the outer ring, and the other end is provided with a second linear slide rail between it and the chassis. The track of the second linear slide rail is fixedly connected to the chassis, and the slider of the second linear slide rail is fixedly connected to the end of the second support rod away from the outer ring.

[0010] Furthermore, a first linear slide rail is provided between the first support rod and the chassis. The first linear slide rail is perpendicular to the second linear slide rail.

The slider of the first linear slide rail is fixedly connected to the end of the first support rod away from the reflector.

[0011] Furthermore, the first support rod is universally connected to the reflector. The reflector includes a frame and a lens mounted on the frame. A connecting block is fixedly connected to the side of the frame away from the lens. The first support rod includes a swing rod, a lock nut, and a vertical rod arranged sequentially on the side of the connecting block away from the frame. One end of the vertical rod is connected to the chassis, and the other end is threaded to the lock nut. One end of the swing rod is fixedly connected to the connecting block, and the other end is a ball head inserted into the lock nut. After the lock nut is tightened, the ball head is clamped between the lock nut and the vertical rod.

[0012] Furthermore, a second lead screw is arranged parallel to the second linear slide rail, the second lead screw is rotatably connected to the chassis, a second nut is fixedly connected to the end of the second support rod away from the condenser lens, the second nut is threadedly connected to the second lead screw, and a second crank is fixedly connected to the end of the second lead screw.

[0013] Furthermore, a first lead screw is arranged parallel to one side of the first linear slide rail. The first lead screw is rotatably connected to the chassis. A first nut is fixedly connected to the end of the first support rod away from the reflector. The first nut is threadedly connected to the first lead screw.

[0014] Furthermore, the second support rod includes a support tube, a third nut, and a third lead screw connected sequentially between the chassis and the condenser lens. The third nut is rotatably connected to the end of the support tube away from the chassis. One end of the third lead screw is inserted into the support tube, and the other end is connected to the condenser lens. The third lead screw and the third nut are connected by a through thread. The third lead screw has a keyway along its axial direction, and a key that can slide within the keyway is provided. The key is fixedly connected to the support tube.

[0015] Furthermore, the condenser lens is one of a convex lens, a converging lens, a prism, a Fresnel lens, or a concave condenser lens.

[0016] The positive effects of this utility model are:

[0017] This invention collects and focuses outdoor sunlight onto an indoor heating container to heat it. Therefore, the heating container can be operated without going outdoors, and the indoor environment is significantly better than the outdoor environment, greatly improving the operator's working conditions. Sunlight passes sequentially through a convex lens and a reflector. The convex lens can be made with a long focal length, thereby reducing its thickness, manufacturing cost, and weight.

[0030] For ease of description, in the following description, the direction that is consistent with the second linear slide rail 7 is "longitudinal", and the direction that is perpendicular to the second linear slide rail 7 in the horizontal plane is "lateral".

[0031] Example 1

[0032] like Figures 1 to 2 As shown, an opening 2 is made in the wall of room 3 on the sunny side. A heating container 1, such as a pot, is placed above the opening 2 inside room 3. A solar indoor / outdoor concentrating collector includes a rectangular base 9, with first omnidirectional casters installed near the four corners of the bottom of the base 9. On the base 9, a first support rod 5 and a reflector 4 are connected sequentially from bottom to top on the left side. The first support rod 5 is vertically arranged. On the base 9, a second support rod 8 and a concentrating mirror 11 are connected sequentially from bottom to top to the right of the first support rod 5. There are two second support rods 8, and the concentrating mirror 11 is mounted between the two second support rods 8. Figure 1 The diagram illustrates the optical path of sunlight passing through a concentrator 11 and a reflector 4. Sunlight strikes the concentrator 11, is focused by it, and then strikes the reflector 4. After being reflected by the reflector 4, the sunlight passes through the opening 2 and converges at the bottom of the heating container 1, heating it. The concentrator 11 is a convex lens. The base 9 can move forward, backward, left, and right, and can also rotate 360° in place, facilitating the tracking of the sun and focusing the light spot onto the bottom of the heating container 1. Simultaneously, the size of the light spot can be adjusted to precisely control the temperature generated when the light spot strikes the bottom of the heating container 1.

[0033] Therefore, the heating container 1 can be operated without going outside room 3, and the environment inside room 3 is significantly better than outside room 3, thus greatly improving the operator's working environment. Because the convex lens can use a long focal length, its thickness can be reduced, lowering manufacturing costs and consequently reducing weight.

[0034] The heating container 1 can be a pot, a solar panel, or other items that need to be heated by focused sunlight.

[0035] Example 2

[0036] Combination Figures 3 to 5 As shown, the difference between this embodiment and Embodiment 1 is that:

[0037] The condenser lens 11 is covered by a frame 10, the frame 10 is fixedly connected to the condenser lens 11, and the condenser lens 11 is rotatably connected to the second support rod 8.

[0038] The frame 10 includes an inner ring 13 and an outer ring 12 that are sequentially fitted around a condenser lens 11. The condenser lens 11 is fixedly connected to the inner ring 13. The inner ring 13 and the outer ring 12 are rotatably connected by a pair of symmetrically arranged pivots 22 on the outer circumference of the inner ring 13. The outer ring 12 is rotatably connected to the second support rod 8 by another pair of symmetrically arranged pivots 22 on the outer circumference of the outer ring 12. These pivots 22 are horizontally arranged, and their axes are perpendicular.

[0039] By moving the condenser lens 11, its orientation can be adjusted so that it can be aligned with the sun, thereby receiving more and stronger sunlight.

[0040] The upper ends of the two second support rods 8 are rotatably connected to both sides of the outer ring 12, and the lower ends are provided with two parallel second linear slide rails 7 between the base 9. Both second linear slide rails 7 are arranged longitudinally, and the tracks of both second linear slide rails 7 are fixedly connected to the base 9. A rectangular strip-shaped second mounting plate 23 is fixedly connected to the top of the slider of the two second linear slide rails 7, and the lower ends of the two second support rods 8 are fixedly connected to the second mounting plate 23.

[0041] A longitudinal second lead screw 24 is arranged parallel between the two second linear slide rails 7. Both ends of the second lead screw 24 are rotatably connected to lugs welded to the base 9. A second nut 26 is fixedly connected to the bottom of the second mounting plate 23, and the second nut 26 is threadedly connected to the second lead screw 24. A second crank 25 is fixedly connected to the end of the second lead screw 24. Cranking the second crank 25 moves the second mounting plate 23 longitudinally, thereby moving the condenser lens 11 longitudinally and adjusting its longitudinal position to facilitate the focusing of light from the condenser lens 11 onto the reflector 4.

[0042] Two parallel horizontal first linear slide rails 6 are provided between the first support rod 5 and the chassis 9. The first linear slide rail 6 is perpendicular to the second linear slide rail 7. The tracks of the two first linear slide rails 6 are fixedly connected to the chassis 9. A rectangular first mounting plate 15 is fixedly connected to the top of the slider of the two first linear slide rails 6. The lower end of the first support rod 5 is fixedly connected to the top center of the first mounting plate 15.

[0043] A first lead screw 20 is provided transversely between the two first linear slide rails 6. The two ends of the first lead screw 20 are respectively rotatably connected to lugs welded to the chassis 9. A first nut 19 is fixedly connected to the bottom of the first mounting plate 15. The first nut 19 is threadedly connected to the first lead screw 20. A first crank 21 is fixedly connected to the end of the first lead screw 20. Cranking the first crank 21 moves the first mounting plate 15 laterally, thereby moving the reflector 4 laterally to facilitate the reception of sunlight gathered by the condenser 11.

[0044] Therefore, when the position of the sun changes, the condenser lens 11 is moved, and the first crank 25 is turned to adjust the vertical position of the condenser lens 11. The second crank 21 is turned to adjust the horizontal position of the reflector 4. Thus, after the angle of sunlight changes, the condenser lens 11 can be aligned with the sun again, and the light gathered by the condenser lens 11 can be irradiated onto the reflector 15.

[0045] Example 3

[0046] Combination Figure 5 and Figure 6 As shown, the first support rod 5 is omnidirectionally connected to the reflector 4. The reflector 4 includes a horizontal frame 27 and a lens 28 mounted on the frame 27. The lens 28 is a plane mirror. A frustum-shaped connecting block 14 is welded to the bottom surface of the frame 27. The first support rod 5 includes a swing rod 16, a lock nut 17, and a vertical rod 18 arranged vertically from top to bottom on the lower side of the connecting block 14. The lower end of the vertical rod 18 is fixedly connected to the first mounting plate 15, and the upper end is threadedly connected to the lock nut 17. The upper end of the swing rod 16 is threadedly connected to the connecting block 14, and the lower end is a ball head inserted into the lock nut 17. After the lock nut 17 is tightened, the ball head is clamped between the lock nut 17 and the vertical rod 18.

[0047] After loosening the lock nut 17, the reflection direction of the reflector 4 can be adjusted. When the reflected light shines on the bottom of the heating container 1 through the hole 2, the lock nut 17 can be locked again, so that even after the position of the sun changes, the light can still be focused on the heating container 1.

[0048] The second support rod 8 includes a support tube 32, a third nut 30, and a third lead screw 29 connected sequentially between the second mounting plate 23 and the condenser lens 11. The third nut 30 is rotatably connected to the upper end of the support tube 32. The lower end of the third lead screw 29 is inserted into the support tube 32, and the upper end is rotatably connected to the outer ring 12. The third lead screw 29 and the third nut 30 are connected by a thread. The third lead screw 29 is provided with a keyway 33 along its axial direction. A key 31 that can slide in the keyway 33 is provided therein. The key 31 is fixedly connected to the support tube 32.

[0049] Four levers are fixedly connected at intervals on the circumference of the third nut 30. Turning the levers causes the third nut 30 to rotate, which in turn causes the third lead screw 29 to move up and down, thereby adjusting the height of the condenser lens 11 and the distance between the condenser lens 11 and the reflector 4. At the same time, by turning the condenser lens 11, shaking the first crank 25, shaking the second crank 21, and adjusting the reflection direction of the reflector 4, the sunlight can be easily focused onto the bottom of the heating container 1 after the position of the sun changes.

[0050] Example 4

[0051] like Figure 7 As shown, the difference between this embodiment and Embodiment 3 is that:

[0052] The upper part of the wall on the sunny side of room 3 protrudes outward, and the opening 2 is located at the bottom of the protruding part, so as to facilitate the tracking of the sun after the sun's position changes, and also to reduce the distance between the chassis and room 3.

[0053] Example 5

[0054] like Figure 8 As shown, the difference between this embodiment and Embodiment 3 is that:

[0055] The heating container 1 is installed on the outer side of the sunny side wall of room 3, so that the heating container 1 can be heated from outdoors.

[0056] Example 6

[0057] like Figure 9 As shown, the difference between this embodiment and Embodiment 3 is that:

[0058] A horizontal turntable 35 is installed on the ground. A reduction motor 34 is fixedly installed near the left end of the turntable 35. The rotation axis of the reduction motor 34 is downward and fixedly connected to the ground. A second omnidirectional caster is provided on the right side of the bottom surface of the turntable 35. There are two second omnidirectional casters centered on the reduction motor 34. The first omnidirectional casters at the bottom of room 3 and chassis 9 are both installed on the turntable 35.

[0059] When the geared motor 34 rotates, it can drive the room 3 and the chassis 9 to rotate around the geared motor 34, thus facilitating the tracking of the sun.

[0060] Example 7

[0061] like Figure 10 As shown, the difference between this embodiment and Embodiment 6 is that:

[0062] The geared motor 34 is located at the center of the turntable 35, and four second swivel casters are evenly distributed around the geared motor 34 along the circumference.

[0063] When the geared motor 34 rotates, it can drive the room 3 and the chassis 9 to rotate around the geared motor 34, thus facilitating the tracking of the sun.
