A solar energy collecting and storing device

Abstract

This invention discloses a solar thermal energy storage device, relating to the field of solar energy storage technology. It includes a water tank, support frames, vacuum tubes, and inlet / outlet ports. Two support frames are respectively installed on the bottom sides of the water tank. The invention utilizes a trigger rod to drive a rotating seat, which, through the cooperation of a planar threaded strip and a translation block, causes three locking plates to move inward synchronously, automatically clamping the vacuum tube placement end. A ratchet and a locking lever ensure that the tubes tighten under their own weight. When inserted into the water tank, a flipping short column and a flipping groove cause the screw to rise, first pushing multiple vacuum tubes to flip before straight insertion. The entire process requires no electricity. Simultaneously, a trumpet-shaped sealing gasket gradually tightens as insertion deepens to enhance sealing, and a support crossbar distributes the end pressure. Multiple adjustable arc-shaped support rings allow for independent fine-tuning of the angle of each vacuum tube, effectively overcoming axial misalignment caused by support frame deformation and comprehensively ensuring installation stability and efficiency.

Description

Technical Field

[0001] This invention relates to the field of solar energy storage technology, specifically to a solar thermal energy storage device. Background Technology

[0002] Solar energy generally refers to the radiant energy of sunlight. It is a renewable energy source, and its basic utilization methods can be divided into four categories: photothermal utilization, photoelectric utilization, photochemical utilization, and photobiological utilization. Among these four types, photothermal conversion technology is the most mature and has the most products. Solar thermal power generation is a new energy technology that collects solar thermal energy through a concentrating system and uses a thermal storage device to achieve continuous power supply. Currently, the most widely used, technologically mature, and economically viable application of solar thermal conversion is in solar water heaters.

[0003] For example, Chinese patent CN113587452B discloses a solar water heater. This patented technology uses a support frame with two support rods to fix the water tank. A movable base plate that can slide along the length of the inclined rod is movably installed at the bottom of the support rod. The movable base plate is provided with a clamping mechanism that can hold the bottom end of the vacuum tube, so that by driving the movable base plate to slide, each vacuum tube can be quickly inserted and installed into the water tank.

[0004] However, the following problems still exist in the implementation of this patented technology:

[0005] Although the patented technology describes how to install vacuum tubes in batches, the clamping mechanism it uses is a uniform clamping method. That is, when the vacuum tubes are installed in the two sets of clamps in sequence, it is only in the initial installation and positioning process. In the stage where all the vacuum tubes are placed into the clamps one by one but have not yet been tightly fixed, the entire installation process is in an extremely unstable state. A gust of wind or a worker accidentally touching the movable base plate may cause individual or even a large number of vacuum tubes to slip out of the clamps, collide with each other and break. Moreover, for maintenance and replacement of vacuum tubes due to damage caused by hail, foreign objects or other factors in daily use, it is impossible to unlock and pull out the broken vacuum tubes to be replaced, resulting in inconvenience in use. Summary of the Invention

[0006] The purpose of this invention is to provide a solar thermal energy collection and storage device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides a solar thermal energy storage device, comprising a water tank, a support frame, vacuum tubes, and inlet / outlet ports. Two support frames are respectively installed on the bottom sides of the water tank. A plurality of vacuum tubes are arrayed on the bottom side of the water tank, and the vacuum tubes are parallel to the diagonal braces of the support frames.

[0008] The top array of the mounting base plate is provided with a clamping self-locking component, which includes three locking plates and a lever. When the vacuum tube is placed in sequence, the placement and pressing of the vacuum tube can drive the three locking plates to move closer to the clamp simultaneously, and the lever can be used to restrict the return of the locking plates, thereby pressing the vacuum tube tighter and tighter.

[0009] The side wall of the support frame is provided with a flip-mounting component, which includes a flip-mounting short column slidably mounted on one side of the two support frames that are close to each other, so as to guide the mounting base plate to flip and move by means of the horizontal movement of the flip-mounting short column:

[0010] The internal array of the support crossbar is provided with an insertion fine-tuning component, which includes an arc-shaped support ring to adjust the insertion angle of the multiple vacuum tubes by means of the minute movement of the multiple arc-shaped support rings.

[0014] Preferably, a torsion spring is fixedly connected to the outer wall of the rotating seat, and the other end of the torsion spring is fixedly connected to the bottom inner wall of the support base. A through hole is provided on the top of the mounting base corresponding to the trigger rod.

[0015] Preferably, the flip-mounting component includes two short support columns, with one end of each short support column being fixedly connected to the outer walls of the two sides of the mounting base plate. A groove is provided on one side of each short support column corresponding to the two adjacent support frames, and the outer wall of the short support column is slidably connected to the inner wall of the groove. A long support column is fixedly connected to one side of the mounting base plate, and a connecting rod is hinged to the outer wall of the long support column. A connecting block is hinged to the other end of the connecting rod, and a screw is fixedly connected to the top of the connecting block. A mounting box is fixedly connected to one side of one of the support frames. The outer wall of the screw is slidably mounted inside the mounting box, and a worm gear is threaded onto the outer wall of the screw.

A worm is rotatably mounted inside the mounting box, and the outer wall of the worm meshes with the outer wall of the worm gear for transmission. A handle is rotatably connected to one side of the outer wall of the mounting box, and one end of the handle is fixedly connected to one end of the worm.

[0016] Preferably, the two adjacent ends of the flipping short columns are respectively fixedly connected to the outer walls of the two sides of the mounting base plate, and the flipping short columns are located between the supporting short columns and the supporting long columns. The two adjacent sides of the supporting frames are provided with a sliding groove II corresponding to the flipping short columns, and the inner wall of the sliding groove II is provided with a flipping groove corresponding to the flipping short columns.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. During the installation of vacuum tubes in a solar water heater, the downward movement of the trigger rod during tube placement causes the rotating seat to rotate. This, combined with the cooperation of the planar threaded strip and the translation block, causes the three locking plates to move inward synchronously, automatically clamping and fixing the placement end of the vacuum tube. This eliminates the risk of semi-fixation during the pre-installation stage. Furthermore, the ratchet and locking lever work together to ensure the vacuum tubes become increasingly tighter after placement due to their own weight, guaranteeing installation stability during sequential placement. The system also allows for subsequent individual disassembly, improving the efficiency of vacuum tube installation and removal, as well as overall operational stability.

[0020] 2. When installing vacuum tubes in a solar water heater, the system utilizes a combination of a flipping short column and a flipping groove to rotate multiple vacuum tubes before straight insertion as the screw rises. This eliminates the need for a motor-driven rotation, reducing power dependence and failure rates, aligning with the trend towards simplified outdoor equipment design. Furthermore, the funnel-shaped sealing gasket compresses the conical inner wall of the gasket as insertion deepens, linearly increasing the contact pressure with the tube wall and resulting in a uniformly rising sealing pressure. This ensures a tighter fit to the microscopic unevenness of the vacuum tube surface, guaranteeing a superior seal. Additionally, the support crossbar provides extra support points for the rotated vacuum tubes, preventing excessive pressure on the clamping points and potential breakage, thus ensuring the integrity of the vacuum tube installation.

[0021] 3. When installing the vacuum tubes of a solar water heater, the insertion angle of each vacuum tube can be finely adjusted by multiple adjustable arc-shaped support rings as the vacuum tube is about to be inserted into the water storage tank. This avoids the problem of the installation axis of some vacuum tubes being misaligned due to deformation of the support frame over time, which would prevent accurate insertion. This helps to ensure the installation efficiency of the vacuum tubes. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1-6This invention provides a solar thermal energy storage device, including a water tank 1, a support frame 2, vacuum tubes 3, and inlet / outlet 4. Two support frames 2 are respectively installed on the bottom of both sides of the water tank 1. Several vacuum tubes 3 are arrayed on the bottom side of the water tank 1. The several vacuum tubes 3 are parallel to the diagonal braces of the support frames 2. Two inlet / outlet 4 are respectively installed on the two end faces of the water tank 1. A mounting base plate 5 is installed on the bottom of the side of the two support frames 2 that is close to each other. A support crossbar 9 is fixedly connected to the side of the two support frames 2 that is close to each other, corresponding to the vacuum tubes 3.

[0031] The top array of the mounting base plate 5 is provided with clamping self-locking components 6.

[0032] Furthermore, the clamping self-locking component 6 includes multiple support bases 601, the bottoms of which are respectively arrayed and fixedly mounted on the top of the mounting base plate 5. A rotating seat 602 is rotatably connected to the inner wall of the bottom of each support base 601, and a chuck 603 is fixedly connected to the top of the rotating seat 602. The outer wall of the chuck 603 is slidably connected to the inner wall of the support base 601. A trigger rod 604 is slidably connected to the middle of both the chuck 603 and the rotating seat 602. A through groove is provided through the bottom of the seat 601, and a limiting block 605 is symmetrically fixedly connected to the inner wall of the through groove. A limiting groove 606 is symmetrically provided on the bottom outer wall of the trigger rod 604, and the outer wall of the limiting block 605 slides against the inner wall of the limiting groove 606. A ball 607 is fixedly connected to the outer wall of the trigger rod 604. A spiral groove 608 is provided on the inner wall of the rotating seat 602 corresponding to the ball 607, and the outer wall of the ball 607 slides against the inner wall of the spiral groove 608.

[0033] Specifically, when installing the vacuum tube 3, the vacuum tube 3 is first placed in the middle of the three locking plates 612 and pressed down. Then, it is fixedly installed on the top of the mounting base plate 5 by the bottom of multiple support bases 601. The bottom inner wall of the support base 601 is rotatably connected to a rotating seat 602, and the top of the rotating seat 602 is fixedly connected to a chuck 603. The outer wall of the chuck 603 is in contact with the inner wall of the support base 601 and is slidably connected to it. The middle of the chuck 603 and the rotating seat 602 are slidably connected to trigger rods 604, so that the top of the trigger rods 604 can be squeezed during the pressing process to make the vacuum tube 3 descend.

[0034] Next, a through groove is provided through the bottom of the support base 601, and a limiting block 605 is symmetrically fixedly connected to the inner wall of the through groove. A limiting groove 606 is symmetrically provided on the bottom outer wall of the trigger rod 604, and the outer wall of the limiting block 605 slides against the inner wall of the limiting groove 606. A ball 607 is fixedly connected to the outer wall of the trigger rod 604. A spiral groove 608 is provided on the inner wall of the rotating seat 602 corresponding to the ball 607, and the outer wall of the ball 607 slides against the inner wall of the spiral groove 608. Thus, the rotation of the trigger rod 604 is limited by the cooperation of the limiting groove 606 and the limiting block 605. Then, the rotation of the rotating seat 602 is driven to rotate by the cooperation of the spiral groove 608 and the ball 607 during the descent of the trigger rod 604.

[0035] Next, a planar threaded strip 609 is fixedly connected to the top of the chuck 603. Three limiting grooves 611 are equally spaced on the top of the support base 601, and a translation block 610 is slidably connected to the inner wall of the limiting groove 611. The bottom of the translation block 610 meshes with the planar threaded strip 609. The opposite sides of the three locking plates 612 are fixedly connected to the opposite ends of the three translation blocks 610. Thus, when the rotating seat 602 drives the chuck 603 to rotate, the limiting grooves 611 can restrict the translation block 610, causing the translation block 610 to move linearly under the drive of the planar threaded strip 609. In turn, it moves inward synchronously with the locking plates 612, automatically clamping and fixing the placement end of the vacuum tube 3, eliminating the semi-fixed risk in the pre-installation stage.

[0036] To ensure stability after clamping, a ratchet 613 is fixedly connected to the outer wall of the rotating base 602. The outer wall of the locking lever 614 is slidably connected to the inner wall of the support base 601. The end of the locking lever 614 away from the ratchet 613 extends through the interior of the support base 601 to the exterior. A handle 615 is rotatably connected to the extended end of the locking lever 614. A tension spring 616 is fixedly connected to one end of the handle 615 facing the locking lever 614. The other end of the tension spring 616 is fixedly connected to the outer wall of the support base 601. Thus, the tension spring 616 can elastically drive the locking lever 614 to press it against the tooth groove of the ratchet 613. During clamping, the ratchet 613 can only rotate in one direction and cannot be reversed to unlock. This allows the vacuum tube 3 to achieve a tightening effect by utilizing its own weight after placement, ensuring installation stability during the sequential placement of the vacuum tube 3.

[0037] Next, a pressure rod 617 is eccentrically fixed to one end of the handle 615 facing the support base 601, and the outer wall of the pressure rod 617 is slidably connected to the inside of the support base 601. A torsion spring 618 is fixedly connected to the outer wall of the rotating seat 602, and the other end of the torsion spring 618 is fixedly connected to the bottom inner wall of the support base 601. A through hole 619 is opened on the top of the mounting base 5 corresponding to the trigger rod 604, so that energy can be stored through the torsion spring 618 during the clamping process. When unlocking, the handle 615 can be pulled outward to drive the locking rod 614 to disengage from the ratchet 613, and automatically reset under the rebound force of the torsion spring 618, thus having the ability to disassemble independently afterwards.

[0038] Then, during single-person operation, after pulling out the handle 615, the vacuum tube 3 is still pressed on the trigger rod 604 and cannot be unlocked. Therefore, by setting the pressure rod 617, after pulling out the handle 615, the pressure rod 617 will be pulled out from the support base 601 at the same time. At this time, the handle 615 can be rotated so that the pressure rod 617 presses against the outer wall of the support base 601 to keep the latch 614 and the ratchet 613 in a continuously disengaged state, which is convenient for single-person operation.

[0039] In Example 2, based on the above examples, the side wall of the support frame 2 is provided with a flip-mounting component 7.

[0040] Furthermore, the flip-mounting component 7 includes two short support columns 701. The ends of the two short support columns 701 that are close to each other are fixedly connected to the outer walls of both sides of the mounting base plate 5. On the side of the two support frames 2 that are close to each other, corresponding to the short support columns 701, a sliding groove 702 is provided, and the outer wall of the short support column 701 is slidably connected to the inner wall of the sliding groove 702. A long support column 703 is fixedly connected to one side of the mounting base plate 5, and a connecting rod 704 is hinged to the outer wall of the long support column 703. A connecting block 705 is hinged to the other end of the connecting rod 704, and the top of the connecting block 705 is fixedly connected to... A screw 706 is attached, and a mounting box 707 is fixedly connected to one side of one of the support frames 2. The outer wall of the screw 706 is slidably installed inside the mounting box 707. A worm gear 708 is threadedly connected to the outer wall of the screw 706, and the two ends of the worm gear 708 are rotatably engaged with the inner wall of the mounting box 707. A worm 712 is rotatably installed inside the mounting box 707, and the outer wall of the worm 712 meshes with the outer wall of the worm gear 708 for transmission. A handle 713 is rotatably connected to one side of the outer wall of the mounting box 707, and one end of the handle 713 is fixedly connected to one end of the worm 712.

[0041] Specifically, after the multiple vacuum tubes 3 are placed and installed, two short support columns 701 are fixedly connected to the outer walls of the mounting base plate 5 on both sides by their adjacent ends. The adjacent sides of the two support frames 2 are provided with corresponding grooves 702 on the short support columns 701, and the outer walls of the short support columns 701 are slidably connected to the inner walls of the grooves 702. A long support column 703 is fixedly connected to one side of the mounting base plate 5, and a connecting rod 704 is hinged to the outer wall of the long support column 703. A connecting block 705 is hinged to the other end of the connecting rod 704. A screw 706 is fixedly connected to the top of block 705. A mounting box 707 is fixedly connected to one side of one of the support frames 2. The handle 713 can be turned to drive the worm gear 712 to rotate, which in turn drives the worm wheel 708 to rotate. The position of the worm wheel 708 is restricted by the mounting box 707. The screw 706 is threaded to the center of the worm wheel 708, and the screw 706 is restricted from rotating. The handle 713 can be turned to drive the screw 706 to rise, and the mounting base plate 5 can be moved by the support column 703.

[0042] To ensure that the mounting base 5 is parallel to the ground during the placement of vacuum tubes 3, facilitating the installation of multiple vacuum tubes 3, and to restore the angled insertion angle during subsequent insertions, the ends of the flip-up short column 709 are fixedly connected to the outer walls of both sides of the mounting base 5. The flip-up short column 709 is located between the support short column 701 and the support long column 703. A second sliding groove 710 is provided on the side of the two support frames 2 that is close to each other, corresponding to the flip-up short column 709. The inner wall of the second sliding groove 710 is provided with a flip groove 711 corresponding to the flip-up short column 709. The inner wall of the flip groove 711 is arc-shaped. The design allows the mounting base plate 5 to rotate using the support column 701 as a fulcrum when the supporting column 703 moves. This is achieved by using the rotating short column 709 and the rotating groove 711 as a pivot point. Once the rotating short column 709 disengages from the rotating groove 711 and slides into the second sliding groove 710, it is unable to continue rotating due to the restriction of the second sliding groove 710. Combined with the cooperation of the support column 701 and the first sliding groove 702, the mounting base plate 5 can then move diagonally without the need for a motor-driven rotation, reducing power dependence and failure rate, and conforming to the trend of simplified design for outdoor equipment.

[0043] To prevent the clamping end of the vacuum tube 3 from being crushed due to excessive pressure during insertion after flipping, the support crossbar 9 is provided to provide additional support points for the multiple vacuum tubes 3 after flipping, thus preventing excessive pressure on the clamping position of the vacuum tube 3 and causing crushing, and ensuring the installation integrity of the vacuum tube 3.

[0044] Next, during insertion, an insertion interface is provided at the connection point between the water tank 1 and the vacuum tube 3. A sealing gasket 10 is fixedly installed on the inner wall of the insertion interface. The sealing gasket 10 is funnel-shaped, with the end of the sealing gasket 10 facing the vacuum tube 3 having the largest opening. Compared with traditional sealing components such as O-rings or flat gaskets, which only have narrow line or point contact in the initial stage of insertion, the sealing pressure is concentrated at one point, which can easily wear down the insertion end of the vacuum tube 3 and may cause leakage. However, with this device, after the vacuum tube 3 is inserted and contacts the sealing gasket 10, the seal becomes stronger as the insertion depth increases. The conical inner wall of the gasket 10 is continuously compressed, and the contact pressure with the tube wall of the vacuum tube 3 insertion end increases linearly. The sealing pressure also rises uniformly until the insertion end of the vacuum tube 3 passes through the sealing gasket 10 and extends into the interior of the water tank 1. It can adapt to scratches, dust or slight ellipticity on the surface of the vacuum tube 3. The trumpet-shaped structure adds a strong axial component force on the basis of radial stress. This axial force forces the sealing gasket 10 material to fit more tightly to compensate for the micro-unevenness on the surface of the vacuum tube 3, ensuring the sealing and leak-proof performance after installation.

[0045] In embodiment three, based on the above embodiments, the internal array of the support crossbar 9 is provided with insertion fine-tuning components 8.

[0046] Furthermore, the support crossbar 9 has grooves 801 arrayed on the side facing the vacuum tube 3, the outer wall of the arc-shaped support ring 802 fits and matches the inner wall of the groove 801, the side of the arc-shaped support ring 802 away from the vacuum tube 3 is rotatably connected to a screw 803, and the other end of the screw 803 is fixedly connected to an adjusting handle 804, the outer wall of the screw 803 is threadedly connected to the inside of the support crossbar 9.

[0047] Specifically, to avoid the problem of inaccurate insertion of vacuum tubes 3 due to the misalignment of the installation axis caused by the deformation of the support frame 2 over time, the outer wall of the arc-shaped support ring 802 is fitted and matched with the inner wall of the groove 801. The side of the arc-shaped support ring 802 away from the vacuum tube 3 is rotatably connected to a screw 803, and the other end of the screw 803 is fixedly connected to an adjusting handle 804. The outer wall of the screw 803 is threadedly connected to the inside of the support crossbar 9. Thus, the position of each arc-shaped support ring 802 that contacts and supports the vacuum tube 3 can be adjusted by rotating the adjusting handle 804, and the insertion angle of each vacuum tube 3 can be finely adjusted, thereby helping to ensure the installation efficiency of the vacuum tube 3.

[0048] Working principle: When installing the vacuum tube 3, the vacuum tube 3 is first placed in the middle of the three locking plates 612 and pressed down. This allows the vacuum tube 3 to squeeze the top of the trigger rod 604 during the pressing process, causing it to descend. The interaction between the limiting groove 606 and the limiting block 605 restricts the rotation of the trigger rod 604. Then, with the interaction between the spiral groove 608 and the ball 607, the trigger rod 604 can drive the rotating seat 602 to rotate during its descent. When the rotating seat 602 drives the chuck 603 to rotate, the limiting groove 611 restricts the translation block 610, causing the translation block 610 to move linearly under the drive of the planar threaded strip 609. This, in turn, moves inward synchronously with the locking plate 612, automatically clamping and fixing the placement end of the vacuum tube 3, eliminating the risk of semi-fixation during the pre-installation stage.

[0049] Next, the tension spring 616 elastically drives the lever 614 to press it against the tooth groove of the ratchet 613, so that during the clamping process, the ratchet 613 can only rotate in one direction and cannot be reversed to unlock. This allows the vacuum tube 3 to achieve a tighter and tighter effect after being placed by its own weight, ensuring the installation stability during the sequential placement of the vacuum tube 3.

[0050] Then, during the clamping process, energy can be stored through the torsion spring 618. When unlocking, the lever 614 can be disengaged from the ratchet 613 by pulling the handle 615 outward, and automatically reset under the rebound force of the torsion spring 618, thus having the ability to disassemble independently afterwards.

[0051] Then, when working alone, after pulling out the handle 615, the vacuum tube 3 is still pressed on the trigger rod 604 and cannot be unlocked. Therefore, by setting the pressure rod 617, after pulling out the handle 615, the pressure rod 617 will be pulled out from the support base 601 at the same time. At this time, the handle 615 can be rotated so that the pressure rod 617 presses against the outer wall of the support base 601 to keep the latch 614 and the ratchet 613 in a continuously disengaged state, which is convenient for single-person operation.

[0052] After the multiple vacuum tubes 3 are placed and installed, the rotatable handle 713 drives the screw 706 to rise, thereby using the support column 703 to move the mounting base plate 5. When the support column 703 moves, the mounting base plate 5 can be rotated with the support column 701 as the fulcrum by the setting of the flipping column 709 and the flipping groove 711. When the flipping column 709 disengages from the flipping groove 711 and slides into the slide groove 710, the flipping column 709 cannot continue to rotate under the restriction of the slide groove 710. With the cooperation of the support column 701 and the slide groove 702, the mounting base plate 5 will move diagonally without the need for motor-driven rotation, reducing power dependence and failure rate, which is in line with the trend of simplified design of outdoor equipment.

[0053] Next, to prevent the clamping end of the vacuum tube 3 from being crushed due to excessive pressure during the insertion process after flipping, the support crossbar 9 is set up to provide additional support points for the multiple vacuum tubes 3 after flipping, so as to avoid excessive pressure on the clamping position of the vacuum tube 3 and the situation of squeezing and cracking, thus ensuring the installation integrity of the vacuum tube 3.

[0054] Next, to avoid the problem of the installation axis of the uniformly inserted vacuum tubes 3 being offset due to the deformation of the support frame 2 over time, which would prevent accurate insertion, the position of each arc-shaped support ring 802 that contacts and supports the vacuum tube 3 can be adjusted by rotating the adjustment handle 804, and the insertion angle of each vacuum tube 3 can be finely adjusted, thereby helping to ensure the installation efficiency of the vacuum tubes 3.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
