Description

Technical Field

[0001] The present invention relates to the technical field of photothermal converters, and particularly to a photothermal converter with double-lens debugging. Background Art

[0002] A photothermal converter is a device or system that can convert sunlight into heat energy. One of the most common photothermal converters is a solar water heater. The solar water heater absorbs sunlight and uses a photothermal converter (such as a solar collector) to convert it into heat energy for heating water. This conversion process can provide hot water supply and reduce the demand for traditional energy sources.

[0003] When the existing photothermal converter is working, since it relies on solar energy for heating, the adjustability of the overall conversion efficiency of the device is poor, and the conversion speed varies greatly in winter and summer environments. There are problems such as a low conversion rate in winter, insufficient water temperature, and too high temperature in summer, resulting in thermal stress cracking, and thus the service life of the photothermal converter is relatively low. Summary of the Invention

[0004] The purpose of the present invention is to provide a photothermal converter with double-lens debugging to overcome the above-mentioned defects in the prior art.

[0005] According to a photothermal converter with double-lens debugging of the present invention, it includes a frame. On the left side of the upper end surface of the frame, an adjustment box is fixedly provided. On the right side of the upper end surface of the frame, a storage box is fixedly provided. On the left end surface of the storage box, multiple converters are fixedly provided. Above the converter, a lower convex lens is rotatably provided. Above the upper end surface of the lower convex lens, an upper concave lens is rotatably provided. The lower end surface of the upper concave lens and the upper end surface of the lower convex lens are arc-shaped and fit each other. The upper concave lens and the lower convex lens are made of lens glass materials and cooperate with each other.

[0006] An adjustment cavity is provided in the adjustment box. On the lower wall of the adjustment cavity, five mounting bases are fixedly provided. Above the mounting base, a driving wheel is rotatably provided. On the front end surface of the upper concave lens, an upper transfer rod is fixedly provided. On the rear end surface of the lower convex lens, a lower transfer shaft is fixedly provided. The left end surfaces of the upper transfer rod and the lower transfer shaft extend into the adjustment cavity, and sliding gears capable of sliding left and right are provided on the outer circumferential surfaces. The sliding gear is key-connected to the upper transfer rod.

[0007] In some embodiments, a rotating motor is fixedly provided on the upper end surface of the mounting base, and the left end surface of the driving wheel is power-connected to the rotating motor.

[0008] In some embodiments, two fixed side frames are fixedly arranged on the upper end surface of the mounting base plate. The right end surface of the fixed side frame is rotatably connected between the upper transfer rod and the lower transfer shaft on the same side. A slidable frame capable of moving left and right is arranged on the lower end surface of the sliding gear. The slidable frame is slidably connected to the sliding gear. A sliding cylinder is fixedly arranged on the lower side of the right end surface of the fixed side frame. The right end surface of the sliding cylinder can perform telescopic movement and is fixedly connected to the left end surface of the slidable frame. A limiting rod is fixedly arranged above the sliding cylinder. The left end surface of the limiting rod is fixedly connected to the right end surface of the fixed side frame. The outer cylindrical surface of the limiting rod is slidably connected to the slidable frame, which can play a role in limiting.

[0009] In some embodiments, an inner cavity is arranged inside the converter. An inner layer pipe is fixedly arranged inside the inner cavity. A storage cavity is arranged inside the storage box. The left wall of the storage cavity is communicated with the right wall of the inner cavity.

[0010] In some embodiments, a temperature detector is fixedly arranged on the upper wall of the inner cavity. The temperature detector can detect the temperature of the inner cavity and the light-facing part of the upper end surface of the converter, and transmit a signal to the outside when the temperature of the converter is too high or too low.

[0011] In some embodiments, five buffer boxes are fixedly arranged on the lower side of the right end surface of the adjustment box. A buffer cavity is arranged inside the buffer box. The left end surface of the converter extends into the buffer cavity. A buffer spring is fixedly connected between the left end surface of the converter and the left wall of the buffer cavity.

[0012] In some embodiments, a blowing frame is fixedly arranged on the upper end surface of the adjustment box. The right end surface of the blowing frame can eject gas. Two air injection pumps are fixedly arranged on the left end surface of the blowing frame.

[0013] In some embodiments, a control panel is fixedly arranged on the right end surface of the frame. The control panel can receive the signals of the temperature detector and the external Internet, and control the start and stop of each sliding cylinder and the rotating motor.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. When the temperature detector detects that the temperature is too high, the present invention can drive the slidable frame to slide by starting the sliding cylinder on one side of the upper transfer rod, so that the sliding gear on one side of the upper transfer rod moves to a position flush with the driving wheel. At this time, by rotating the sliding gear on this side counterclockwise by 90 degrees, the upper concave lens on the upper side is rotated 90 degrees to the front side. At this time, the sunlight on the upper side will shine on the lower convex lens on the lower side, and under the characteristic of the cylindrical protrusion on the upper end surface of the lower convex lens, the light divergence work is realized, so as to reduce the thermal conversion work amplitude of the converter, and thus slowly reduce the temperature on the surface and inside of the converter to a suitable range.

[0016] 2. When the temperature detected by the temperature detector is too low, the invention can activate the sliding cylinder on one side of the lower transfer shaft, drive the sliding frame to move left and right, thus driving the sliding gear on one side of the lower transfer shaft to slide to a position flush with the driving wheel. By making the driving wheel rotate counterclockwise, the sliding gear on this side is driven to rotate, and then the lower transfer shaft together with the lower convex lens is driven to rotate downward by 90 degrees. At this time, the sunlight on the upper side penetrates the upper concave lens and converges on one side of the upper end face of the converter under the action of the concave surface on the lower end face of the upper concave lens, realizing the light concentration work, thereby increasing the surface temperature of the converter and increasing the photothermal conversion efficiency of the invention.

[0017] 3. The invention enables the air injection pump to absorb external air and blow it to one side of the upper concave lens, the lower convex lens and the converter through the blowing frame. Through high-speed air blowing, it can reduce the surface temperature of the upper concave lens and the lower convex lens and perform dust removal work. At the same time, after moving the sliding gears on both sides to the right to be flush with the driving wheel, when the driving wheel rotates, the upper concave lens and the lower convex lens on the upper side both move away from above the converter. Under the blowing work of the blowing frame, it can further accelerate the cooling speed of the converter, so as to provide emergency heat dissipation work when the temperature detected by the temperature detector is too high and difficult to drop for a long time, improving the safety performance of the invention.

[0018] 4. When the converter is performing heat conversion work, the buffer spring can reduce the thermal stress extrusion caused by the thermal expansion and contraction of the converter, preventing the converter from cracking due to thermal expansion and contraction, thereby further improving the safety performance and service life of the invention.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Refer to Figures 1 - 8 , which is the first embodiment of the present invention. This embodiment provides an embodiment of a photothermal converter for double-lens debugging, including a frame 11. On the left side of the upper end face of the frame 11, an adjustment box 12 is fixedly provided. On the right side of the upper end face of the frame 11, a storage box 18 is fixedly provided. On the left end face of the storage box 18, multiple converters 20 are fixedly provided. Above the converter 20, a lower convex lens 16 is rotatably provided. Above the upper end face of the lower convex lens 16, an upper concave lens 15 is rotatably provided. The lower end face of the upper concave lens 15 and the upper end face of the lower convex lens 16 are arc-shaped and fit each other. The upper concave lens 15 and the lower convex lens 16 are made of lens glass materials and cooperate with each other;

[0032] The adjustment box 12 is provided with an adjustment cavity 21. Five mounting bottom plates 27 are fixedly arranged on the lower wall of the adjustment cavity 21. A driving wheel 25 is rotatably arranged above the mounting bottom plate 27. A upper adapter rod 17 is fixedly arranged on the front end face of the upper concave lens 15. A lower adapter shaft 34 is fixedly arranged on the rear end face of the lower convex lens 16. The left end faces of the upper adapter rod 17 and the lower adapter shaft 34 extend into the adjustment cavity 21, and sliding gears 24 capable of sliding left and right are arranged on the outer circumferential surfaces thereof. A key connection is adopted between the sliding gear 24 and the upper adapter rod 17.

[0033] A rotating motor 23 is fixedly arranged on the upper end face of the mounting bottom plate 27. The left end face of the driving wheel 25 is power-connected to the rotating motor 23. When the rotating motor 23 is started, it drives the driving wheel 25 to rotate counterclockwise, thereby driving the sliding gear 24 in the same plane as it to rotate. After the front sliding gear 24 meshes with the driving wheel 25, it drives the upper adapter rod 17 to rotate, thereby driving the upper concave lens 15 to rotate upward by ninety degrees.

[0034] Two fixed side frames 31 are fixedly arranged on the upper end face of the mounting bottom plate 27. The right end faces of the fixed side frames 31 are rotatably connected to the upper adapter rod 17 and the lower adapter shaft 34 on the same side. A sliding frame 33 capable of moving left and right is arranged on the lower end face of the sliding gear 24. A sliding connection is adopted between the sliding frame 33 and the sliding gear 24. A sliding cylinder 22 is fixedly arranged on the lower side of the right end face of the fixed side frame 31. The right end face of the sliding cylinder 22 can perform telescopic movement and is fixedly connected to the left end face of the sliding frame 33. A limiting rod 32 is fixedly arranged above the sliding cylinder 22. The left end face of the limiting rod 32 is fixedly connected to the right end face of the fixed side frame 31. The outer circumferential surface of the limiting rod 32 is slidably connected to the sliding frame 33, which can play a limiting role. When the sliding cylinder 22 is started, it drives the sliding frame 33 to move left and right, thereby driving the sliding gear 24 to slide between the upper adapter rod 17 and the lower adapter shaft 34, thereby adjusting the connection relationship between the driving wheel 25 and the sliding gear 24.

[0035] An inner cavity 28 is provided in the converter 20. An inner layer pipe 29 is fixedly arranged in the inner cavity 28. A storage cavity 26 is provided in the storage box 18. The left wall of the storage cavity 26 is communicated with the right wall of the inner cavity 28.

[0036] By activating the sliding cylinder 22 on one side of the upper transfer rod 17, the sliding frame 33 can be driven to slide, so that the sliding gear 24 on one side of the upper transfer rod 17 moves to a position flush with the driving wheel 25. At this time, by activating the rotating motor 23, the sliding gear 24 on this side can be driven to rotate counterclockwise by 90 degrees, thereby driving the upper transfer rod 17 to rotate by 90 degrees, and then causing the upper concave lens 15 on the upper side to rotate by 90 degrees to the front side. At this time, the sunlight on the upper side will shine on the lower convex lens 16 on the lower side, and under the characteristic of the cylindrical protrusion on the upper end face of the lower convex lens 16, the light divergence work can be realized, thereby reducing the thermal conversion work range of the converter 20, and then slowly reducing the surface and internal temperature of the converter 20 to a suitable range.

[0037] The sliding cylinder 22 on one side of the lower transfer shaft 34 can be activated to drive the sliding frame 33 to move left and right, so as to drive the sliding gear 24 on one side of the lower transfer shaft 34 to slide to a position flush with the driving wheel 25, and by activating the rotating motor 23, the driving wheel 25 can be driven to rotate counterclockwise, thereby driving the sliding gear 24 on this side to rotate, and further driving the lower transfer shaft 34 together with the lower convex lens 16 to rotate downward by 90 degrees. At this time, the sunlight on the upper side penetrates the upper concave lens 15 and will converge on one side of the upper end face of the converter 20 under the action of the concave surface on the lower end face of the upper concave lens 15, realizing the light concentration work, thereby increasing the surface temperature of the converter 20 and increasing the photothermal conversion work efficiency of the present invention.

[0038] Embodiment 2

[0039] Refer to Figures 1 - 8 , in order to prevent the converter 20 from overheating during the thermal conversion work, resulting in thermal stress cracking or fragmentation due to thermal expansion, a buffer box 37 and a temperature detector 30 are provided;

[0040] A temperature detector 30 is fixedly provided on the upper wall of the inner cavity 28. The temperature detector 30 can detect the temperature of the inner cavity 28 and the light-facing part of the upper end face of the converter 20, and transmit a signal to the outside when the temperature of the converter 20 is too high or too low.

[0041] Five buffer boxes 37 are fixedly provided on the lower side of the right end face of the adjustment box 12. A buffer cavity 35 is provided in the buffer box 37. The left end face of the converter 20 extends into the buffer cavity 35, and a buffer spring 36 is fixedly connected between the left end face of the converter 20 and the left wall of the buffer cavity 35.

[0042] A blowing rack 13 is fixedly arranged on the upper end surface of the adjustment box 12. The right end surface of the blowing rack 13 can eject gas. Two air injection pumps 14 are fixedly arranged on the left end surface of the blowing rack 13. The air injection pumps 14 can inject air into the blowing rack 13, so that external air is sprayed to one side of the upper concave lens 15, the lower convex lens 16 or the converter 20 through the blowing rack 13.

[0043] A control panel 19 is fixedly arranged on the right end surface of the machine frame 11. The control panel 19 can receive the signals of the temperature detector 30 and the external Internet, and control the start and stop of the sliding cylinders 22 and the rotating motor 23 at various positions.

[0044] During the conversion work, the air injection pumps 14 and the blowing rack 13 can be started to enable the air injection pumps 14 to absorb external air and blow it to one side of the upper concave lens 15, the lower convex lens 16 and the converter 20 through the blowing rack 13. High-speed air blowing can be used to reduce the surface temperature of the upper concave lens 15 and the lower convex lens 16 and perform dust removal work. At the same time, after moving the sliding gears 24 on both sides to the right to be flush with the driving wheel 25, the upper concave lens 15 and the lower convex lens 16 on the upper side can be separated from above the converter 20 under the rotation of the driving wheel 25. Under the blowing work of the blowing rack 13, the cooling speed of the converter 20 can be further increased, so that when the temperature detected by the temperature detector 30 is too high for a long time and difficult to drop, emergency heat dissipation work can be provided to improve the safety performance of the present invention.

[0045] During the heat conversion work of the converter 20, the buffer spring 36 can reduce the thermal stress extrusion caused by the thermal expansion and contraction of the converter 20, prevent the converter 20 from cracking due to thermal expansion and contraction, and thus can further improve the safety performance and service life of the present invention.

[0046] Specific working process:

[0047] During the photothermal conversion work, the machine frame 11 can be installed on the top surface of an external building, with the converter 20 on the light-facing side, and then the photothermal conversion work can be carried out.

[0048] During the photothermal conversion work, the temperature detector 30 can continuously detect the temperature on the upper end surface and inside the cavity 28 of the converter 20, and transmit the temperature signal to the control panel 19. When the temperature is within the normal range, the upper concave lens 15 and the lower convex lens 16 on the upper side are in a stacked state, and the sunlight on the upper side is evenly incident on one side of the converter 20, and the heat conversion work proceeds normally.

[0049] When the temperature detector 30 detects that the temperature is too high, the sliding cylinder 22 on one side of the upper transfer rod 17 can be activated to drive the sliding frame 33 to slide, so that the sliding gear 24 on one side of the upper transfer rod 17 moves to a position flush with the driving wheel 25. At this time, when the rotation motor 23 is started, the sliding gear 24 on this side can be driven to rotate counterclockwise by 90 degrees, thereby driving the upper transfer rod 17 to rotate by 90 degrees, so that the upper concave lens 15 on the upper side rotates by 90 degrees to the front side. At this time, the sunlight on the upper side will shine on the lower convex lens 16 on the lower side, and under the characteristic of the cylindrical protrusion on the upper end surface of the lower convex lens 16, the light divergence work is realized, thereby reducing the thermal conversion work amplitude of the converter 20, and thus slowly reducing the temperature on the surface and inside of the converter 20 to a suitable range.

[0050] When the temperature detector 30 detects that the temperature is too low, the sliding cylinder 22 on one side of the lower transfer shaft 34 can be activated to drive the sliding frame 33 to move left and right, so as to drive the sliding gear 24 on one side of the lower transfer shaft 34 to slide to a position flush with the driving wheel 25, and by starting the rotation motor 23, drive the driving wheel 25 to rotate counterclockwise, thereby driving the sliding gear 24 on this side to rotate, and further driving the lower transfer shaft 34 together with the lower convex lens 16 to rotate downward by 90 degrees. At this time, the sunlight on the upper side penetrates the upper concave lens 15, and under the action of the concave surface on the lower end surface of the upper concave lens 15, it converges on one side of the upper end surface of the converter 20, realizing the light concentration work, thereby increasing the surface temperature of the converter 20, and thus increasing the photothermal conversion work efficiency of the present invention.

[0051] During the conversion work, by starting the air injection pump 14 and the blowing frame 13, the air injection pump 14 can absorb the outside air and blow it to one side of the upper concave lens 15, the lower convex lens 16 and the converter 20. It can reduce the surface temperature of the upper concave lens 15 and the lower convex lens 16 and carry out dust removal work through high-speed air blowing. At the same time, after moving the sliding gears 24 on both sides to the right to be flush with the driving wheel 25, under the rotation of the driving wheel 25, the upper concave lens 15 and the lower convex lens 16 on the upper side both leave above the converter 20. Under the blowing work of the blowing frame 13, it can further accelerate the cooling speed of the converter 20, so as to provide emergency heat dissipation work when the temperature detected by the temperature detector 30 is too high for a long time and difficult to drop, and improve the safety performance of the present invention.

[0052] During the thermal conversion work of the converter 20, the buffer spring 36 can reduce the thermal stress extrusion caused by the thermal expansion and contraction of the converter 20, and prevent the converter 20 from cracking due to thermal expansion and contraction, thereby further improving the safety performance and service life of the present invention.

[0053] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
