Description

Technical Field

[0001] The present application relates to the technical field of collectors, and in particular to a sun-chasing solar thermal collector. Background Art

[0002] A solar thermal collector is a device that collects solar radiation energy and converts it into thermal energy for utilization through interaction with matter. Currently, the most commonly used solar collection devices are mainly flat-plate collectors, vacuum tube collectors and focusing collectors. Usually, solar thermal utilization is divided into low-temperature utilization, medium-temperature utilization and high-temperature utilization according to the different temperatures that can be achieved and the different uses. When cruise ships are traveling on the water, they often need to use solar thermal collectors to collect and store energy.

[0003] The invention patent with the authorization announcement number CN117928112B discloses a light-chasing solar thermal collector, including a carrier plate, a protective frame rotatably connected to the top of the carrier plate, a solar thermal collector plate arranged on the top of the protective frame, a frame plate arranged outside the solar thermal collector plate, a light-chasing mechanism arranged on the top of the carrier plate, a mounting plate arranged at the bottom of the carrier plate, a shock-absorbing mechanism arranged on the top of the mounting plate, and a cleaning assembly arranged on the frame plate. The solar thermal collector plate is driven to move by the light-chasing mechanism, and the collector is buffered and shock-absorbed by the shock-absorbing mechanism.

[0004] However, since the solar thermal collector is externally installed obliquely above the carrier plate and the collector is designed to be angular, when the collector needs to be carried, the collector not only takes up a large space, but also easily causes damage to the solar thermal collector. Summary of the invention

[0005] In order to improve the portability of the collector, the present application provides a sun-chasing type solar thermal collector.

[0006] The present application provides a tracking solar thermal collector, which adopts the following technical solution:

[0007] A light-chasing solar thermal collector comprises a base, a light-chasing seat is movably arranged on the top surface of the base, the base is provided with a moving mechanism for driving the light-chasing seat to move and chase light, a fixed seat is swingably arranged on the top surface of the light-chasing seat, a receiving groove is provided on the surface of the fixed seat, a heat collecting plate is provided in the receiving groove, a photoresistor is provided on the surface of the fixed seat, the photoresistor is electrically connected to the moving mechanism, and the light-chasing seat is provided with a folding component for folding and storing the fixed seat.

[0008] By adopting the above technical solution, the heat collecting plate is installed through the accommodating groove to protect the heat collecting plate. When the collector needs to be used, the fixing seat is unfolded through the folding component, and the heat collecting plate is tilted and installed on the top surface of the light chasing seat through the fixing seat. When light shines on the photoresistor, the photoresistor transmits the electrical signal to the moving mechanism, and the heat collecting plate is finally driven to move toward the light through the moving mechanism. After use, the storage fixing seat is reset through the folding component, which reduces the overall size of the collector, thereby facilitating the convenience of carrying the collector.

[0009] Optionally, the folding assembly includes a first hinged rod and a second hinged rod, the first hinged seat is provided on both inner sides of the light-chasing seat, the second hinged seat is symmetrically provided on the bottom surface of the fixed seat, the first hinged rod and the second hinged rod are both provided in the light-chasing seat, one end of the first hinged rod and the second hinged rod are respectively hinged to the first hinged rod, the other end of the first hinged rod and the second hinged rod are respectively hinged to the second hinged seat, and the light-chasing seat is provided with a tightening member for cooperating to drive the fixed seat to move.

[0010] By adopting the above technical solution, under the connection action of the first hinged rod and the second hinged rod, the fixed seat swings in the direction away from the light chasing seat. At the same time, with the cooperation of the tightening member, the fixed seat is positioned at the end of the swing, which is beneficial to improve the convenience of folding and storing the solar collector and tilting the solar collector for collection.

[0011] Optionally, the tightening member is a first spring, the first spring is arranged in the light-chasing seat, one end of the first spring is connected to the first hinge seat, and the other end of the first spring is connected to the second hinge seat.

[0012] By adopting the above technical solution, when the heat collecting plate needs to be tilted to collect heat, the fixing seat is flipped up and swung in the direction away from the light chasing seat. At this time, the fixing seat is flipped along the swinging path of the first hinged rod and the second hinged rod, and the fixing seat stretches the first spring. When the fixing seat is released, the first spring releases the elastic force and drives one end of the fixing seat to press against the top surface of the light chasing seat, thereby finally tilting the heat collecting plate. Similarly, when the fixing seat is reset and flipped, the fixing seat is reset and flipped along the swinging path of the first hinged rod and the second hinged rod, and the first spring is stretched again. When the fixing seat is released, the spring releases the elastic force and presses the fixing seat against the top surface of the light chasing seat, which is beneficial to improve the stability of the fixing seat in the positioning at the swinging end.

[0013] Optionally, the moving mechanism includes a spline shaft and a sleeve, a first motor is arranged in the base, the spline shaft is coaxially connected to the output end of the first motor, the sleeve sliding sleeve is arranged on the spline shaft, the top end of the sleeve extends above the base, the top end of the sleeve is fixedly connected to the bottom surface of the light chasing seat, the first motor is electrically connected to the photoresistor, and the base is provided with a lifting component for driving the sleeve to rise and fall.

[0014] By adopting the above technical solution, when the first motor is started, the output shaft of the first motor drives the spline shaft to rotate, the spline shaft drives the sleeve to rotate, the sleeve drives the light-chasing seat to rotate, and the light-chasing seat finally drives the heat collecting plate to rotate. Since the sleeve and the spline shaft slide relative to each other, under the lifting assembly, the sleeve rises and falls relative to the spline shaft, the sleeve drives the light-chasing seat to rise and fall, and the light-chasing seat finally drives the heat collecting plate to rise and fall, which is beneficial to improve the stability of the lifting and rotation of the heat collecting plate.

[0015] Optionally, the lifting assembly includes a gear, a second motor is provided on the inner wall of the base, an output shaft of the second motor is coaxially connected to the gear, a climbing tooth is provided on the side wall of the sleeve, the gear is meshed with the climbing tooth, and the second motor is electrically connected to the photoresistor.

[0016] By adopting the above technical solution, when the second motor is started, the output shaft of the second motor drives the gear to rotate, the gear engages with the climbing gear, the gear drives the shaft sleeve to rise and fall through the climbing gear, the shaft sleeve drives the light chasing seat to rise and fall, and the light chasing seat finally drives the solar collector to rise and fall, which is beneficial to improve the stability of the solar collector plate lifting and falling.

[0017] Optionally, two heat collecting plates are provided, two photoresistors are provided, the two photoresistors are arranged between the two heat collecting plates, and the fixing seat is provided with a spacing mechanism for separating the two photoresistors.

[0018] By adopting the above technical solution, the two photoresistors are separated by a spacing mechanism, so that the division of labor of the two photoresistors is clearer, which is beneficial to improving the recognition of the light source direction by the photoresistors.

[0019] Optionally, the spacing mechanism includes a spacer block, a surface of the fixing seat is provided with an embedding groove, the spacer block is slidably arranged in the embedding groove, the two photoresistors are symmetrically arranged on both sides of the spacer block, a handle is provided on the surface of the spacer block, and the fixing seat is provided with a fixing component for fixing the spacer block.

[0020] By adopting the above technical solution, when it is necessary to separate two photoresistors, the spacer is pulled out of the groove by the handle, and then fixed by the fixing assembly. At this time, the spacer separates the two photoresistors, so that when light shines on one of the photoresistors, one of the photoresistors is not interfered by the other photoresistor, thereby sending out a more accurate electrical signal, which is beneficial to improve the accuracy of the photoresistor signal transmission.

[0021] Optionally, the fixing assembly includes an insert rod, and sliding grooves are provided on both sides of the spacer block, the insert rod slides in the sliding grooves, the fixing seat is provided with a slot based on the slot wall of the embedding slot, one end of the insert rod is plugged into the slot, the side wall ring of the insert rod is provided with a pressure ring, the side wall of the insert rod is sleeved with a second spring, one end of the second spring is connected to the side wall of the pressure ring, and the other end of the second spring is connected to the slot wall of the slot.

[0022] By adopting the above technical solution, when the insertion rod moves in a direction away from the slot, the insertion rod squeezes the second spring through the pressure ring. When the insertion rod is released, the second spring releases the elastic force and drives the insertion rod to move in a direction close to the slot through the pressure ring. At this time, the insertion rod is inserted into the slot, which is beneficial to improve the stability of the spacer fixed in the groove.

[0023] Optionally, a buried groove is provided on the top surface of the fixed seat, a piston air pump is hingedly arranged in the buried groove, the piston end of the piston air pump is hinged to the bottom surface of the fixed seat, a hose is provided to connect the pump barrel of the piston air pump, an air pipe assembly is pre-installed in the fixed seat, the air pipe assembly is connected to the accommodating groove, and the end of the hose away from the piston air pump is connected to the air pipe assembly.

[0024] By adopting the above technical solution, when the fixing seat is swung and unfolded, the fixing seat stretches the piston air pump. When the collector is used for a long time, the surface of the heat collecting plate is easily stained with dust. When the heat collecting plate is folded and stored, the fixing seat squeezes the piston air pump, and the piston air pump discharges gas. The gas is ejected through the hose and the air pipe assembly in turn, thereby blowing air to the surface of the heat collecting plate to blow off the dust on the surface of the heat collecting plate, so that the dust on the surface of the heat collecting plate can be cleaned when the fixing seat is folded and stored, which is beneficial to improve the convenience of cleaning the dust on the surface of the heat collecting plate.

[0025] In summary, this application includes the following beneficial technical effects:

[0026] The heat collecting plate is installed through the accommodating groove to protect the heat collecting plate. When the collector needs to be used, the fixing seat is unfolded through the folding component, and the heat collecting plate is installed obliquely on the top surface of the light chasing seat through the fixing seat. When light shines on the photoresistor, the photoresistor transmits the electrical signal to the moving mechanism, and the heat collecting plate is finally driven to move toward the light through the moving mechanism. After use, the storage fixing seat is reset through the folding component to reduce the overall size of the collector, which is conducive to improving the convenience of carrying the collector.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Example:

[0035] See also Figure 1 and Figure 2A light-chasing solar thermal collector comprises a base 1. The base 1 is cylindrical in shape, and a light-chasing seat 2 is movably mounted on the top surface of the base 1. The light-chasing seat 2 is in the shape of a rectangular parallelepiped. The base 1 is mounted with a moving mechanism, and the moving mechanism is used to drive the light-chasing seat 2 to move in a light-chasing manner. A fixed seat 3 is swingably mounted on the top surface of the light-chasing seat 2, and a folding assembly is mounted on the light-chasing seat 2, and the folding assembly is used to fold and store the fixed seat 3. A receiving groove 4 is provided on the surface of the fixed seat 3, and the number of the receiving grooves 4 is set to two, and the two receiving grooves 4 are symmetrically arranged about the center line of the fixed seat 3. The two receiving grooves 4 are respectively mounted with heat collecting plates 5, and the heat collecting plates 5 are plates that absorb sunlight incident through a transparent cover layer and convert light energy into heat energy, and heat is transferred by a heat collecting fluid. A photoresistor 6 is fixedly mounted on the surface of the fixed seat 3, and a control system 31 is installed in the base 1, and the control system 31 is electrically connected to the photoresistor 6 and the moving mechanism respectively.

[0036] The control system 31 is a conventional method in this field. The control system 31 includes a chip and a processor. The control system 31 is used to receive the electrical signal of the photoresistor 6 and send a moving electrical signal to the moving mechanism. The photoresistor 6 can convert the optical signal into an electrical signal. When light is irradiated on the photoresistor 6, the photoresistor 6 converts the optical signal into an electrical signal, and then transmits the electrical signal to the control system 31. The control system 31 then transmits the electrical signal to the moving mechanism. The moving mechanism drives the light chasing seat 2 to move, and the light chasing seat 2 finally drives the heat collecting plate 5 to move in the direction of light irradiation, thereby realizing the light chasing function.

[0037] When the collector needs to be carried, the fixing seat 3 is folded and stored on the top surface of the light-chasing seat 2 through the folding assembly, reducing the overall volume of the collector and improving the convenience of carrying. Conversely, when the collector needs to be used for heat collection, the fixing seat 3 is unfolded through the folding assembly. At this time, the fixing seat 3 is inclined to the top surface of the light-chasing seat 2, and the inclined heat collecting plate 5 is conducive to maximizing the contact with light.

[0038] For details, see Figure 2 , the moving mechanism includes a spline shaft 7 and a sleeve 8. A first motor 9 is fixedly installed in the base 1, and the output shaft of the first motor 9 is vertically upward. The spline shaft 7 is installed in the base 1, and the spline shaft 7 is vertically arranged. The bottom end of the spline shaft 7 is coaxially fixedly connected with the output shaft of the first motor 9. The sleeve 8 is slidingly sleeved on the side wall of the spline shaft 7, and the top end of the sleeve 8 passes through the top surface of the base 1, and the top end of the sleeve 8 is fixedly connected with the bottom center of the light chasing seat 2. Among them, the first motor 9 is electrically connected to the photoresistor 6 and the control system 31 respectively.

[0039] In addition, in order to further improve the light-chasing ability of the heat collecting plate 5, the base 1 is also equipped with a lifting assembly, which includes a gear 10. A second motor 11 is fixedly installed on the inner wall of the base 1, and the output shaft of the second motor 11 is coaxially fixedly connected to the gear 10. The side wall of the sleeve 8 is fixedly connected with a climbing tooth 12, which is distributed along the vertical direction of the sleeve 8, and the gear 10 is meshed with the climbing tooth 12. Among them, the second motor 11 is electrically connected to the photoresistor 6 and the control system 31 respectively.

[0040] When light shines on the photoresistor 6, the photoresistor 6 converts the light signal into an electrical signal and transmits it to the control system 31. The control system 31 then transmits the electrical signal to the first motor 9. The first motor 9 starts, and the output shaft of the first motor 9 drives the spline shaft 7 to rotate. The spline shaft 7 drives the shaft sleeve 8 to rotate. The shaft sleeve 8 then drives the light chasing seat 2 to rotate. The light chasing seat 2 drives the heat collecting plate 5 to rotate through the fixed seat 3. At this time, the heat collecting plate 5 rotates in the direction of the light.

[0041] In addition, when the light rises, the photoresistor 6 converts the light signal into an electrical signal and transmits it to the control system 31. The control system 31 then transmits the electrical signal to the second motor 11. The second motor 11 starts, and the output shaft of the second motor 11 drives the gear 10 to rotate. The gear 10 drives the sleeve 8 to rise through the climbing gear 12, and the sleeve 8 drives the light chasing seat 2 to rise. The light chasing seat 2 drives the heat collecting plate 5 to rise through the fixed seat 3. At this time, the heat collecting plate 5 rises in the direction of the light.

[0042] For details, see Figure 3 The folding assembly includes a first hinged rod 13 and a second hinged rod 14. The first hinged seat 15 is fixedly installed on both symmetrical inner sides of the light chasing seat 2. The second hinged seat 16 is symmetrically fixedly installed on the bottom surface of the fixed seat 3 corresponding to the position of the first hinged seat 15. The number of the first hinged rod 13 and the second hinged rod 14 is provided in two groups, the length of the first hinged rod 13 is shorter than the length of the second hinged rod 14, one end of the first hinged rod 13 is hinged to the first hinged seat 15, and the other end of the first hinged rod 13 is hinged to the second hinged seat 16. One end of the second hinged rod 14 is hinged to the first hinged seat 15, and the other end of the second hinged rod 14 is hinged to the second hinged seat 16.

[0043] It should be noted that see Figure 3 To cooperate with the positioning fixing seat 3, the light chasing seat 2 is also equipped with a tightening member, which is a first spring 17. The first spring 17 is also provided with two groups, one end of the first spring 17 is fixedly connected to the first hinge seat 15, and the other end of the first spring 17 is fixedly connected to the second hinge seat 16.

[0044] When the heat collecting plate 5 needs to be used for heat collection, the fixing seat 3 is first turned up, and the fixing seat 3 swings along the swing path of the first hinge rod 13 and the second hinge rod 14, and the fixing seat 3 stretches the first spring 17. When the fixing seat 3 is released, the first spring 17 releases the elastic force and drives the fixing seat 3 to press against the direction close to the light chasing seat 2. At this time, the fixing seat 3 is tilted and pressed against the top surface of the light chasing seat 2, that is, the heat collecting plate 5 is tilted to absorb the heat of the sun. Similarly, when the folding fixing seat 3 needs to be reset, the fixing seat 3 is swung in the opposite direction, so that the fixing seat 3 stretches the first spring 17 again. At this time, the fixing seat 3 is flipped in the opposite direction along the swing path of the first hinge rod 13 and the second hinge rod 14. When the fixing seat 3 is released, the first spring 17 releases the elastic force, and finally the fixing seat 3 is flatly covered on the top surface of the light chasing seat 2, completing the folding and storage of the heat collecting plate 5.

[0045] It is worth mentioning that see Figure 3 The top surface of the light-chasing seat 2 is provided with a slot 18, and the fixing seat 3 is plugged into the slot 18. When the fixing seat 3 is tilted and pressed against the top surface of the light-chasing seat 2, one end of the fixing seat 3 is plugged into the slot 18. At the same time, under the restriction of the slot 18, it is beneficial to further improve the stability of the heat collecting plate 5 when it is tilted and placed for heat collection.

[0046] See also Figure 1 , Figure 4 and Figure 5 In order to improve the light tracking stability of the heat collecting plate 5, two photoresistors 6 are provided. The two photoresistors 6 are installed between the two heat collecting plates 5, and the fixing seat 3 is installed with a spacing mechanism, which is used to separate the two photoresistors 6.

[0047] The spacing mechanism includes a spacer 19, which is in a T shape. A groove 20 is provided on the surface of the fixing seat 3 corresponding to the shape of the spacer 19, and the groove 20 is located between the two heat collecting plates 5, and the spacer 19 is plugged into the groove 20. In addition, the two photoresistors 6 are symmetrically arranged with the spacer 19 as the center. A handle 21 is fixedly connected to the top surface of the spacer 19.

[0048] It should be noted that, in order to facilitate fixing after the spacer 19 is pulled out, the fixing seat 3 is installed with a fixing assembly, and the fixing assembly includes an insertion rod 22. Slide grooves 23 are provided on both sides of the spacer 19, and the insertion rod 22 is slidably installed in the slide grooves 23, and one end of the insertion rod 22 extends outside the slide groove 23, and the other end of the insertion rod 22 is used for moving. The fixing seat 3 is provided with a slot 24 based on the groove wall of the embedded groove 20, and one end of the insertion rod 22 is plugged into the slot 24. The side wall fixing ring of the insertion rod 22 is provided with a pressure ring 25, and the side wall of the insertion rod 22 is sleeved with a second spring 26, one end of the second spring 26 is fixedly connected to the pressure ring 25, and the other end of the second spring 26 is fixedly connected to the groove wall of the slot 24.

[0049] When the partition is needed, the partition is taken out from the embedded groove 20 by means of the handle 21, and when one end of the insertion rod 22 is aligned with the slot 24, the spring releases the elastic force and drives the insertion rod 22 to slide toward the slot 24 through the pressure ring 25. At this time, one end of the insertion rod 22 is inserted into the slot 24, the spacer 19 is fixed at the current position, and the two photoresistors 6 are separated.

[0050] When light is irradiated on one of the photoresistors 6, the spacer 19 blocks the light to prevent the light from irradiating on the other photoresistor 6. When one of the photoresistors 6 receives a light signal and the light signal moves, one of the photoresistors 6 converts the light signal into an electrical signal and sends the electrical signal to the control system 31, and finally drives the light chasing seat 2 to rotate or rise and fall through the control system 31, so that the heat collecting plate 5 always faces the light, thereby achieving light chasing.

[0051] See also Figure 1 , Figure 3 and Figure 4 When the heat collecting plate 5 is used for a long time to chase the light, dust is easily adhered to the surface of the heat collecting plate 5. In order to clean the dust on the surface of the heat collecting plate 5 while the heat collecting plate 5 is folded and stored, a buried groove 27 is provided on the top surface of the fixing seat 3, and a piston air pump 28 is hingedly installed in the buried groove 27. The piston air pump 28 includes a pump barrel and a piston end. The pump barrel is hinged to the groove wall of the buried groove 27, and the piston end is hinged to the bottom surface of the fixing seat 3. An air pipe assembly 29 is pre-installed in the fixing seat 3, and the air pipe assembly 29 is connected to the accommodating groove 4. A hose 30 is fixedly connected to the side wall of the pump barrel, and the end of the hose 30 away from the pump barrel is fixedly connected to the air pipe assembly 29.

[0052] When the heat collecting plate 5 is tilted for heat collection, the piston air pump 28 is in a stretched state. When the heat collecting plate 5 is folded and swung for storage, the fixing seat 3 squeezes the piston end, and the piston end squeezes the gas in the pump barrel to the hose 30, and the gas is blown out through the air pipe assembly 29, and finally the dust on the surface of the heat collecting plate 5 is blown off.

[0053] It is worth mentioning that after the fixing seat 3 is evenly covered with the top surface of the light-chasing seat 2, the cover body can be used to cover the top surface of the fixing seat 3, so as to avoid damage to the heat collecting plate 5 when the collector is carried.

[0054] The working principle of a sun-chasing solar thermal collector:

[0055] When the collector needs to be used, the fixing seat 3 is first flipped up, and the fixing seat 3 swings along the swing path of the first hinge rod 13 and the second hinge rod 14, and the fixing seat 3 stretches the first spring 17. When the fixing seat 3 is released, the first spring 17 releases the elastic force and drives the fixing seat 3 to press in the direction close to the light chasing seat 2. At this time, the fixing seat 3 is tilted and pressed in the slot 18 on the top surface of the light chasing seat 2, that is, the heat collecting plate 5 is tilted.

[0056] Then, the partition is taken out from the embedded groove 20 by means of the handle 21, and when one end of the insertion rod 22 is aligned with the slot 24, the spring releases its elastic force and drives the insertion rod 22 to slide toward the slot 24 through the pressure ring 25. At this time, one end of the insertion rod 22 is inserted into the slot 24, the spacer 19 is fixed at the current position, and the two photoresistors 6 are separated.

[0057] When light is irradiated on one of the photoresistors 6, the spacer 19 blocks the light to prevent the light from irradiating on the other photoresistor 6. When one of the photoresistors 6 receives a light signal and the light signal moves, one of the photoresistors 6 converts the light signal into an electrical signal and sends the electrical signal to the control system 31, and finally drives the light chasing seat 2 to rotate or rise and fall through the control system 31, so that the heat collecting plate 5 always faces the light, thereby achieving light chasing.

[0058] When the collector is used up, the fixing seat 3 is separated from the card slot 18, and resets and swings along the swing path of the first hinge rod 13 and the second hinge rod 14, and finally flatly covers the top surface of the light chasing seat 2 under the elastic force of the first spring 17. It should be noted that during the reset and swinging process of the fixing seat 3, the fixing seat 3 squeezes the piston end, and the piston end squeezes the gas in the pump barrel to the hose 30, and the gas is blown out through the air pipe assembly 29, and finally the dust on the surface of the heat collecting plate 5 is blown off.

[0059] In summary, by resetting the storage fixing seat 3 through the folding assembly, the overall size of the collector is reduced, thereby facilitating the convenience of carrying the collector.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
