Description

Technical Field

[0001] This application belongs to the technical field of solar heat exchangers, and particularly relates to a solar heat exchanger. Background Art

[0002] A solar heat exchanger utilizes the irradiation of solar light to convert solar energy into heat energy, and then transfers the heat energy to a fluid to increase the temperature of the fluid. Its principle can be divided into two types: direct heating and indirect heating. In direct heating, solar energy directly irradiates the fluid to convert solar energy into heat energy. In indirect heating, solar energy irradiates a radiation plate, and the radiation plate then transfers the heat to the fluid. This type of solar heat exchanger usually consists of a solar heat radiation plate and a heat exchanger. The solar heat radiation plate absorbs solar light and converts it into heat energy, and the heat exchanger transfers the heat energy generated by the radiation plate to the fluid.

[0003] The patent with the publication number CN211316620U discloses a water flow circulation heat exchanger based on solar heating, which includes a water tank. A support rod is welded to the top surface of the water tank. A solar tube is installed on one side of the support rod. A heat conduction column is installed at the bottom of the solar tube through one side of the water tank. A heat exchange coil is installed inside the water tank. One end of the heat exchange coil passes through the box door and is welded to a first water inlet pipe. The other end of the heat exchange coil passes through the box door and is welded to a water outlet pipe. A second water inlet pipe is welded through one end of the box door.

[0004] The above patent adjusts the height by setting a support column and a rolling cylinder, and locks it with a screw. Although a fixed effect can be achieved, simply relying on bolts for fastening has a poor effect. After long-term support of heavy objects and then disassembling and tightening again, the thread will wear, and finally the fixed effect cannot be achieved, so improvement is needed. Utility Model Content

[0005] The purpose of this application is to provide a solar heat exchanger that can solve the above problems.

[0006] The purpose of this application is to provide a solar heat exchanger, including:

[0007] A water tank with a heat exchange component installed inside;

[0008] A solar tube arranged on the top of the water tank;

[0009] A support device arranged at the bottom of the water tank, including a base, a telescopic rod and a locking mechanism;

[0010] Among them, the telescopic rod includes a support rod and an adjustment rod slidably arranged inside the support rod, and the locking mechanism is used to fix the support rod and the adjustment rod.

[0011] By adopting the above-mentioned solar heat exchanger, by installing the heat exchange component in the water tank and setting the solar tube on the top of the water tank, it is possible to effectively collect solar energy and convert it into heat energy to heat the water in the water tank, thereby achieving efficient energy conversion. The design of the support device allows the entire solar heat exchanger to be adjusted in height and angle according to actual needs during installation, thereby optimizing the reception of sunlight. At the same time, the locking mechanism ensures the stability of the support rod and the adjustment rod after adjustment, enhancing the overall adaptability and installation flexibility of the equipment. The base serves as the supporting part of the support device, which is used to keep the heat exchanger stable and not shaken during operation. The design of the telescopic rod and the locking mechanism ensures the safe operation of the equipment in complex environments.

[0012] Furthermore, the locking mechanism comprises:

[0013] The main locking structure includes an adjustment gap arranged on the support rod and an adjuster sleeved outside the support rod and used to tighten the support rod;

[0014] The secondary locking structure includes a mounting protrusion, a stopper matched with the mounting protrusion, and a fastener matched with the stopper thread. The fastener can be rotated to pass through the mounting protrusion and the support rod in sequence and then matched with the adjustment rod.

[0015] The size of the adjustment gap is adjusted by turning the adjuster, so that the support rod clamps the adjustment rod to complete the fixation.

[0016] By setting up the main locking structure, the support rod and the adjustment rod can be initially locked. When locking, the distance of the adjustment gap on the support rod can be adjusted by turning the adjuster. As the distance of the adjustment gap becomes smaller, the diameter of the support rod becomes smaller, thereby clamping the adjustment rod inside the support rod to complete the fixation of the telescopic rod. After the main locking structure is locked, the fastener is rotated so that the fastener passes through the mounting protrusion, the support rod, and then contacts the adjustment rod in sequence, thereby completing the secondary fixation. The combined use of the main locking structure and the secondary locking structure provides double protection for the fixation of the telescopic rod, further enhances the connection strength between the support rod and the adjustment rod, and ensures that the telescopic rod can remain stable and not shake in any usage scenario.

[0017] Further: the regulator comprises:

[0018] A limiting ring, with mounting lugs provided at both ends;

[0019] A limit rod, one end of which passes through the mounting lug and the other end of which is provided with a limit head;

[0020] A holding part, one end of which is connected to one end of the limit rod passing through the mounting lug, and an eccentric rotating shaft is provided at one end of the holding part connected to the limit rod, and the holding part is rotatably connected to the limit rod through the eccentric rotating shaft;

[0021] Wherein, an activity space is formed between the two mounting lugs, a first elastic member is arranged in the activity space, and the first elastic member is sleeved on the limiting rod.

[0022] In this application, the regulator is used to adjust the adjustment gap. During adjustment, the user can toggle the holding part. Since the holding part is rotationally connected to the limiting rod through an eccentric rotating shaft, when the larger-radius end of the holding part is pressed against the mounting lug under the influence of the eccentric rotating shaft, the distance between the two mounting lugs becomes smaller, and the first elastic member is squeezed, thereby squeezing the adjustment gap, making the gap of the adjustment gap smaller, and further tightening the support rod and fixing the adjustment rod. At the same time, when the smaller-radius end of the holding part is pressed against the mounting lug under the influence of the eccentric rotating shaft, the distance between the two mounting lugs becomes larger under the influence of the reset of the first elastic member. At this time, the gap of the adjustment gap is reset, and further, the support rod and the adjustment rod can move relative to each other, and the adjustment of the telescopic rod can be continued.

[0023] Furthermore, a separation ring is arranged at the contact part between the holding part and the mounting lug, and the separation ring is sleeved on the limiting rod.

[0024] By providing the separation ring, direct contact between the holding part and the mounting lug can be avoided. Since the holding part is the main part operated by the user, frequent operation may cause friction and wear between the holding part and the mounting lug, and the arrangement of the separation ring can effectively prevent the occurrence of such wear, thereby prolonging the service life of the regulator.

[0025] Furthermore, a protective layer is arranged on the inner wall of the limiting ring, and a strip-shaped groove adapted to the adjustment gap is arranged on the protective layer.

[0026] The protective layer is arranged on the inner wall of the limiting ring, which plays a role in protecting the outer wall of the support rod from wear. A strip-shaped groove adapted to the adjustment gap is arranged on the protective layer, which can deform together with the limiting ring when the limiting ring deforms, avoiding affecting the tightening of the adjustment gap and the tightening work of the support rod.

[0027] Furthermore, the secondary locking structure further includes:

[0028] A through hole, arranged on the mounting protrusion and penetrating through the support rod, and a concave ring is arranged inside it;

[0029] An adjusting ring, arranged on the fastening member and capable of sliding in the through hole;

[0030] A second elastic member, arranged between the concave ring and the adjusting ring and sleeved outside the fastening member;

[0031] Wherein, the adjusting ring can move along with the movement of the fastening member.

[0032] The through hole is arranged on the mounting projection and penetrates through the support rod, providing a passage for the fastener and the adjusting ring to pass through. The design of the through hole enables the secondary locking structure to be integrated into the support rod, without occupying extra space, while ensuring the compactness of the structure. The concave ring is arranged inside the through hole, providing a support point for the second elastic member and used to ensure that the second elastic member can be stably installed in the through hole and generate sufficient elastic force when compressed. The adjusting ring is arranged on the fastener and can slide inside the through hole, enabling the user to drive the adjusting ring to move inside the through hole by rotating the fastener, thereby realizing the adjustment of the locking force between the support rod and the adjusting rod. The fastener is in threaded cooperation with the limiting member, and the support rod and the adjusting rod can be locked by rotating the fastener. The second elastic member is arranged between the concave ring and the adjusting ring and sleeved outside the fastener. The second elastic member generates elastic force when compressed, not only providing a pre-tightening force for the fastener to ensure the initial stability of the locking, but also being able to assist the disassembly process through the elastic force when disassembling the fastener, making the disassembly easier and more convenient.

[0033] The beneficial effects of this application are as follows:

[0034] 1. By setting the locking mechanism, the stability of the support rod and the adjusting rod after adjustment can be ensured, enhancing the overall adaptability and installation flexibility of the device. The base, as the supporting part of the supporting device, is used to keep the heat exchanger stable and non-shaking during operation. In combination with the design of the telescopic rod and the locking mechanism, the safe operation of the device in a complex environment is ensured;

[0035] 2. By using the main locking structure and the secondary locking structure in combination, double guarantee is provided for the fixation of the telescopic rod, further enhancing the connection strength between the support rod and the adjusting rod, and ensuring that the telescopic rod can remain stable and non-shaking in any usage scenario;

[0036] 3. The support rod and the adjusting rod can be locked by rotating the fastener. The second elastic member is arranged between the concave ring and the adjusting ring and sleeved outside the fastener. The second elastic member generates elastic force when compressed, not only providing a pre-tightening force for the fastener to ensure the initial stability of the locking, but also being able to assist the disassembly process through the elastic force when disassembling the fastener, making the disassembly easier and more convenient.

[0045] Next, with reference to the accompanying drawings, the solar heat exchanger provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0046] Embodiment 1:

[0047] As Figures 1 to 3 shown, the embodiment of the present application provides a solar heat exchanger, including:

[0048] A water tank 100, inside which a heat exchange component is installed;

[0049] The solar tube 110 is disposed on the top of the water tank 100;

[0050] The supporting device is arranged at the bottom of the water tank 100, and includes a base 300, a telescopic rod 400 and a locking mechanism;

[0051] The telescopic rod 400 includes a support rod 410 and an adjustment rod 420 slidably disposed in the support rod 410 , and the locking mechanism is used to fix the support rod 410 and the adjustment rod 420 .

[0052] In some implementations of the embodiments of the present application, Figure 1 As shown, by using the above-mentioned solar heat exchanger, by installing the heat exchange component in the water tank 100 and setting the solar tube 110 on the top of the water tank 100, it is possible to effectively collect solar energy and convert it into heat energy, heat the water in the water tank 100, and achieve efficient energy conversion. The design of the support device allows the entire solar heat exchanger to be adjusted in height and angle according to actual needs during installation, thereby optimizing the reception effect of sunlight. At the same time, the locking mechanism ensures the stability of the support rod 410 and the adjustment rod 420 after adjustment, enhancing the overall adaptability and installation flexibility of the equipment. The base 300 serves as the supporting part of the support device, which is used to keep the heat exchanger stable and not shaken during operation. The design of the telescopic rod 400 and the locking mechanism ensures the safe operation of the equipment in complex environments.

[0053] Embodiment 2:

[0054] An embodiment of the present application provides a solar heat exchanger. In addition to the above-mentioned technical features, the solar heat exchanger of the embodiment of the present application also includes the following technical features.

[0055] like Figures 2 to 4 As shown, the locking mechanism includes:

[0056] The main locking structure 500 includes an adjustment gap 510 disposed on the support rod 410 and an adjuster 520 sleeved outside the support rod 410 and used to tighten the support rod 410;

[0057] The secondary locking structure 600 includes a mounting protrusion 610, a stopper 620 matched with the mounting protrusion 610, and a fastener 630 threadedly matched with the stopper 620. By rotating the fastener 630, the fastener 630 can pass through the mounting protrusion 610 and the support rod 410 in sequence and then match with the adjustment rod 420.

[0058] The size of the adjustment gap 510 is adjusted by toggling the adjuster 520 , so that the support rod 410 clamps the adjustment rod 420 to complete the fixation.

[0059] In the embodiment of the present application, the support rod 410 and the adjustment rod 420 can be initially locked by setting the main locking structure 500. When locking, the distance of the adjustment gap 510 on the support rod 410 can be adjusted by turning the adjuster 520. As the distance of the adjustment gap 510 decreases, the diameter of the support rod 410 decreases accordingly, thereby clamping the adjustment rod 420 in the support rod 410 to complete the fixation of the telescopic rod 400. After the main locking structure 500 is locked, the fastener 630 is rotated so that the fastener 630 sequentially passes through the mounting protrusion 610, the support rod 410 and then contacts the adjustment rod 420, thereby completing the secondary fixation. The combined use of the main locking structure 500 and the secondary locking structure 600 provides double protection for the fixation of the telescopic rod 400, further enhances the connection strength between the support rod 410 and the adjustment rod 420, and ensures that the telescopic rod 400 can remain stable and not shake in any use scenario.

[0060] Embodiment 3:

[0061] An embodiment of the present application provides a solar heat exchanger. In addition to the above-mentioned technical features, the solar heat exchanger of the embodiment of the present application also includes the following technical features.

[0062] like Figures 2 to 5 As shown, the regulator 520 includes:

[0063] The limiting ring 521 has mounting lugs 522 at both ends thereof;

[0064] A limiting rod 523, one end of which passes through the mounting lug 522, and the other end of which is provided with a limiting head 524;

[0065] The holding portion 525 has one end connected to one end of the limiting rod 523 passing through the mounting lug 522, and an eccentric shaft 526 is provided at one end of the holding portion 525 connected to the limiting rod 523, and the holding portion 525 is rotatably connected to the limiting rod 523 via the eccentric shaft 526;

[0066] An activity space 527 is formed between the two mounting lugs 522 . A first elastic member 528 is disposed in the activity space 527 , and the first elastic member 528 is sleeved on the limiting rod 523 .

[0067] In the embodiment of the present application, in the present application, the adjuster 520 is used to adjust the adjustment gap 510. When adjusting, the user can turn the holding portion 525. Since the holding portion 525 is rotatably connected to the limit rod 523 through the eccentric rotating shaft 526, when the holding portion 525 is pressed with one end of the larger radius onto the mounting lug 522 under the influence of the eccentric rotating shaft 526, the distance between the two mounting lugs 522 becomes smaller, and the first elastic member 528 is squeezed, thereby squeezing the adjustment gap 510, making the gap of the adjustment gap 510 smaller, thereby tightening the support rod 410 and fixing the adjustment rod 420. At the same time, when the holding portion 525 presses the end with a smaller radius onto the mounting lug 522 under the influence of the eccentric rotating shaft 526, the distance between the two mounting lugs 522 becomes larger due to the reset effect of the first elastic member 528. At this time, the gap of the adjustment gap 510 is reset, so that the support rod 410 and the adjustment rod 420 can move relative to each other, and the adjustment of the telescopic rod 400 can continue.

[0068] Furthermore, a spacer ring 529 is provided at the contact portion between the holding portion 525 and the mounting lug 522 , and the spacer ring 529 is sleeved on the limiting rod 523 .

[0069] By providing an isolation ring 529, direct contact between the holding portion 525 and the mounting lug 522 can be avoided. Since the holding portion 525 is the main part of the user's operation, frequent operation may cause friction and wear between the mounting lug 522, and the provision of the isolation ring 529 can effectively prevent the occurrence of such wear, thereby extending the service life of the regulator 520.

[0070] Furthermore, a protective layer 530 is provided on the inner wall of the limiting ring 521 , and a strip groove adapted to the adjustment gap 510 is provided on the protective layer 530 .

[0071] The protective layer 530 is arranged on the inner wall of the limiting ring 521, and plays a role in protecting the outer wall of the support rod 410 from wear. The protective layer 530 is provided with a strip groove adapted to the adjustment gap 510, and can be deformed together with the limiting ring 521 when it is deformed, so as to avoid affecting the tightening of the adjustment gap 510 and the tightening work of the support rod 410.

[0072] Embodiment 4:

[0073] An embodiment of the present application provides a solar heat exchanger. In addition to the above-mentioned technical features, the solar heat exchanger of the embodiment of the present application also includes the following technical features.

[0074] like Figure 2 and Figure 5 As shown, the secondary locking structure 600 also includes:

[0075] The through hole 640 is provided on the mounting projection 610 and penetrates the support rod 410, and a concave ring 641 is provided inside thereof;

[0076] The adjusting ring 650 is provided on the fastener 630 and can slide within the through hole 640;

[0077] The second elastic member 660 is provided between the concave ring 641 and the adjusting ring 650 and is sleeved outside the fastener 630;

[0078] Wherein, the adjusting ring 650 can move along with the movement of the fastener 630.

[0079] In the embodiment of the present application, the through hole 640 is provided on the mounting projection 610 and penetrates the support rod 410, providing a passage for the fastener 630 and the adjusting ring 650 to pass through. The design of the through hole 640 enables the secondary locking structure 600 to be integrated into the support rod 410 without occupying additional space, while ensuring the compactness of the structure. The concave ring 641 is provided inside the through hole 640, providing a support point for the second elastic member 660 and ensuring that the second elastic member 660 can be stably installed in the through hole 640 and generate sufficient elastic force when compressed. The adjusting ring 650 is provided on the fastener 630 and can slide within the through hole 640, enabling the user to drive the adjusting ring 650 to move within the through hole 640 by rotating the fastener 630, thereby realizing the adjustment of the locking force between the support rod 410 and the adjusting rod 420. The fastener 630 is in threaded cooperation with the limiting member 620, and the locking of the support rod 410 and the adjusting rod 420 can be realized by rotating the fastener 630. The second elastic member 660 is provided between the concave ring 641 and the adjusting ring 650 and is sleeved outside the fastener 630. When the second elastic member 660 is compressed, it will generate elastic force, which not only provides a pre-tightening force for the fastener 630 to ensure the initial stability of the locking, but also can assist the disassembly process through the elastic force when the fastener 630 is disassembled, making the disassembly easier and more convenient.

[0080] It should be noted that in this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
