Description

[0002] Currently, solar heat pipe collectors, as a clean energy utilization device, are widely used in hot water supply systems in residential, commercial, and industrial sectors.

[0003] However, existing solar heat pipe collectors have significant shortcomings in corrosion resistance. On the one hand, most existing collectors lack corrosion protection mechanisms and cannot actively withstand corrosion reactions, leading to internal wall corrosion, thinning, or even damage to the collector components after long-term use. This not only affects heat transfer efficiency but may also cause fluid leakage risks. On the other hand, some devices use bolts or other methods to fix the corrosion-resistant components to the collector tubes, which requires a lot of maintenance time when the corrosion-resistant components fail due to corrosion. Moreover, the replacement process can easily cause secondary damage to the collector components, further shortening the overall service life of the equipment. Therefore, we propose a solar heat pipe collector with a corrosion-resistant structure that is easy to replace and maintain. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-7 This utility model provides a technical solution: a solar heat pipe collector, comprising: The insulated water tank 1 has an insulated cavity inside, which is used to store the fluid to be heated and keep the stored fluid warm to reduce heat loss. When the collector is running, the fluid to be heated is first injected into the insulated cavity of the insulated water tank 1. After the collector tube 2 converts solar energy into heat energy and transfers it to the fluid, the insulated cavity will block the heat from spreading to the outside. Even during periods without sunlight, the fluid temperature can be kept stable, thereby achieving the effect of continuously storing fluid and reducing heat loss, which greatly improves the insulation effect and energy utilization efficiency of the fluid. The solar collector 2 is fixedly installed on the insulated water tank 1 to absorb solar energy and convert it into heat energy to heat the fluid in the insulated water tank 1. When sunlight shines, the heat-absorbing layer of the solar collector 2 efficiently captures solar radiation energy, converts it into heat energy, and then transfers it to the fluid in the water tank through the connection between the solar collector 2 and the insulated water tank 1, causing the fluid temperature to gradually rise. The tubular structure of the solar collector 2 can maximize the contact with sunlight and increase the heat absorption area, thereby achieving the function of efficiently converting solar energy and heating the fluid, and thus greatly improving the thermal energy conversion efficiency of the system. Multiple sets of sealing rings 3 are evenly spaced and installed on the circumferential side of the heat collector tube 2 to prevent fluid leakage inside the heat collector tube 2 and heat loss caused by the entry of external air. During the assembly of the heat collector, multiple sets of sealing rings 3 are installed at equal intervals along the circumferential side of the heat collector tube 2. Their annular structure fits tightly against the outer wall of the heat collector tube 2, filling the gap between the heat collector tube 2 and the metal rod assembly 4, preventing fluid inside the heat collector tube 2 from seeping out from the gap, and at the same time isolating external cold air from entering the heat collection area, preventing heat from being carried away by the cold air. This achieves the functions of sealing and preventing leakage and blocking the heat loss channel, thereby greatly improving the sealing performance and heat retention effect of the system. Metal rod assembly 4 is mounted on sealing ring 3 and is used to preferentially induce corrosion reaction through sacrificial anode to protect the heat collector tube 2 from corrosion. During the operation of the heat collector, the anode head 403 of metal rod assembly 4 extends into the inner cavity of heat collector tube 2 and comes into contact with the fluid. Because the anode head 403 is made of a metal material with higher electrochemical activity than heat collector tube 2, it will preferentially undergo oxidation reaction with the corrosive medium in the fluid, consuming itself to prevent corrosion of the inner wall of heat collector tube 2. When the anode head 403 is worn to a certain extent, it can be disassembled and replaced to continue to play a protective role. Thus, it achieves the effect of preferentially resisting corrosion to protect heat collector tube 2, thereby greatly improving the service life of heat collector tube 2 and system durability.

[0020] The spring-loaded locking assembly 5 is mounted on the sealing ring 3 and is used to quickly and easily detach and fix the metal rod assembly 4 and the sealing ring 3, thereby improving the assembly and maintenance efficiency of the metal rod assembly 4. When assembling the metal rod assembly 4, after inserting the main rod 402 of the metal rod assembly 4 into the mounting hole 301 of the sealing ring 3, the fixing ring 501 of the spring-loaded locking assembly 5 will wrap around the rotating head 401. The locking rods 4013 on both sides of the rotating head 401 will pop out and lock into the locking holes 502 of the fixing ring 501 under the action of the locking spring 4012, thus completing the fixation. During maintenance, pressing the locking rods 4013 will release the lock and quickly disassemble the metal rod assembly 4, thereby achieving the functions of quick assembly and convenient disassembly of the metal rod assembly 4, and thus greatly improving the assembly efficiency and subsequent maintenance convenience of the metal rod assembly 4. Tail bracket 7 is installed at the end of the collector tube 2 away from the insulated water tank 1. It is used to support and position the end of the collector tube 2 away from the insulated water tank 1 to ensure the stability of the collector tube 2 installation. During the collector installation stage, the tail bracket 7 and the insulated water tank 1 are fixed from both ends of the collector tube 2. The support structure of the tail bracket 7 supports the free end of the collector tube 2, counteracts the downward force generated by the weight of the collector tube 2 itself, and resists the impact of external forces such as wind on the collector tube 2. This prevents the collector tube 2 from bending or breaking due to uneven stress, thereby achieving the function of supporting and positioning the free end of the collector tube 2, and thus greatly improving the stability of the collector tube 2 installation and the overall structural strength of the system. Furthermore, the inner wall of the insulated water tank 1 is equipped with multiple sets of arc-shaped flow-guiding protrusions, which are evenly distributed along the axial direction of the inner wall of the insulated water tank 1. When the heat collection pipe 2 transfers heat into the insulated water tank 1, the fluid in the water tank that is close to the heat collection pipe 2 is heated first, its density decreases, and it flows upward. At this time, the arc-shaped flow-guiding protrusions will guide the low-temperature fluid to flow towards the heat collection pipe 2, forming an orderly convection circulation. This avoids the low-temperature fluid from depositing at the bottom of the water tank, which would cause uneven heating. This allows all the fluid in the water tank to come into uniform contact with the heat, thereby achieving the effect of guiding the fluid circulation and avoiding uneven heating, and thus greatly improving the heating uniformity and heating efficiency of the fluid. Furthermore, the circumferential side of the sealing ring 3 has multiple sets of mounting holes 301, and a sealing sleeve 302 is installed inside the mounting holes 301. When assembling the metal rod assembly 4, the main rod 402 of the metal rod assembly 4 is inserted into the sealing sleeve 302 in the mounting hole 301. The sealing sleeve 302 tightly wraps the outer wall of the main rod 402, filling the gap between the main rod 402 and the mounting hole 301, preventing the fluid in the heat collection tube 2 from leaking from the gap between the mounting hole 301 and the main rod 402, and preventing external air from entering the heat collection tube 2 through the gap. This achieves the function of sealing the gap between the mounting hole 301 and the main rod 402, thereby greatly improving the overall sealing effect of the sealing ring 3. Furthermore, both the mounting hole 301 and the sealing sleeve 302 are conical, and the inner diameter of the opening at the end of the mounting hole 301 and the sealing sleeve 302 closest to the heat collector tube 2 is smaller than the inner diameter of the opening at the end furthest from the heat collector tube 2. When the main rod 402 of the metal rod assembly 4 is inserted, the conical structure guides the main rod 402 to be inserted precisely. As the main rod 402 is pushed toward the heat collector tube 2, the fit between the sealing sleeve 302 and the main rod 402 gradually increases, and the gap gradually decreases, forming a sealing effect that becomes tighter as it is inserted. At the same time, the conical structure can also enhance the fixing effect of the mounting hole 301 on the sealing sleeve 302, preventing the sealing sleeve 302 from falling off. This achieves the effect of guiding the main rod 402 to be installed precisely and enhancing the sealing effect, thereby greatly improving the installation accuracy and sealing reliability. Furthermore, the inner wall of the sealing sleeve 302 is provided with multiple annular sealing grooves 303, and sealing rings 304 are fixedly connected inside the annular sealing grooves 303. When the sealing sleeve 302 wraps around the main rod body 402 of the metal rod assembly 4, the sealing rings 304 in the annular sealing grooves 303 will deform under the compression of the main rod body 402, tightly adhering to the outer wall of the main rod body 402, forming multiple annular sealing barriers. Even if one sealing ring 304 is slightly damaged, the other sealing rings 304 can still maintain the sealing effect and avoid leakage, thereby achieving the function of constructing multiple sealing barriers and enhancing sealing redundancy, thus greatly improving the sealing tolerance and long-term sealing effect of the sealing sleeve 302. Furthermore, the metal rod assembly 4 includes a rotating head 401, with a main rod 402 fixedly connected to the bottom of the rotating head 401. An anode head 403 is threadedly connected to the bottom of the main rod 402, and the anode head 403 extends into the inner cavity of the heat collection tube 2. Elastic elements are provided on both sides of the rotating head 401. During assembly, the operator holds the metal rod assembly 4 through the rotating head 401 and inserts the main rod 402 into the sealing sleeve 302. The elastic elements assist in locking with the spring-loaded locking assembly 5. When the anode head 403 needs to be replaced due to corrosion, it can be removed from the main rod 402 by simply rotating the anode head 403 through the threaded structure. After replacing the new anode head 403, it can be reinstalled without replacing the entire metal rod assembly 4. This achieves the functions of convenient gripping and assembly and individual replacement of the anode head 403, thereby greatly improving the ease of assembly and the economy of component replacement. Furthermore, the elastic element includes grooves 4011 formed on both sides of the rotating head 401. A locking spring 4012 is fixedly connected to the inner wall of the groove 4011, and a locking rod 4013 is fixedly connected to the other end of the locking spring 4012. During the process of inserting the metal rod assembly 4 into the spring lock assembly 5, the locking rod 4013 will first be squeezed by the fixing ring 501, compressing the locking spring 4012 and retracting into the groove 4011. When the locking rod 4013 moves to the position of the locking hole 502, the locking spring 4012 releases its elastic force, pushing the locking rod 4013 to pop out and lock into the locking hole 502, thus achieving automatic locking. When disassembling, pressing the locking rod 4013 to compress the spring will retract it, thereby achieving the functions of automatic locking and convenient unlocking, which greatly improves the cooperation efficiency and operation convenience of the metal rod assembly 4 and the spring lock assembly 5. Furthermore, the spring lock assembly 5 includes a fixing ring 501 installed on the outer wall of the sealing ring 3. Both sides of the fixing ring 501 are provided with locking holes 502 that are adapted to the locking rod 4013. When assembling the metal rod assembly 4, the fixing ring 501 provides installation and positioning space for the rotating head 401, ensuring that the locking rod 4013 can be accurately aligned with the locking hole 502. When the locking rod 4013 is engaged in the locking hole 502, the fixing ring 501 restricts the movement of the locking rod 4013 through the locking hole 502, thereby fixing the position of the metal rod assembly 4. During maintenance, the structure of the fixing ring 501 also facilitates the operation of the locking rod 4013 by the staff, thereby achieving the function of positioning and fixing the metal rod assembly 4, and thus greatly improving the stability and ease of operation of the metal rod assembly 4.

[0021] Furthermore, the main rod 402 is located inside the mounting hole 301, and the outer wall of the main rod 402 is interference-fitted with the inner conical surface of the sealing sleeve 302. During assembly, after the main rod 402 is inserted into the sealing sleeve 302, the interference fit structure causes the sealing sleeve 302 to undergo slight deformation, tightly wrapping the outer wall of the main rod 402 and eliminating the gap between them. At the same time, the friction generated by the interference fit can initially fix the position of the main rod 402, and the auxiliary spring lock assembly 5 achieves double fixation, preventing the main rod 402 from shaking during operation. This enhances the sealing effect and initially fixes the main rod 402, thereby greatly improving the sealing performance and stability of the metal rod assembly 4 installation. Furthermore, both the bottom of the insulated water tank 1 and the tail frame 7 are fixedly connected to support legs 8. During the installation of the solar collector, the support legs 8 at the bottom of the insulated water tank 1 will contact the ground to support the weight of the water tank and the fluid inside. The support legs 8 at the bottom of the tail frame 7 will support the weight of the tail frame 7 and the free end of the solar collector tube 2. At the same time, the support legs 8 can be adjusted in height to ensure that the insulated water tank 1 and the tail frame 7 are on the same horizontal plane, avoiding uneven stress on the solar collector tube 2 due to installation tilt. This achieves the function of supporting the overall weight of the equipment and adjusting the installation level, thereby greatly improving the stability and horizontal accuracy of the solar collector installation.

[0022] Working Principle: In centralized hot water supply systems for urban residential communities, independent hot water preparation for rural households, and hot water supply projects for industrial and commercial plants, the solar heat pipe collector needs to complete the assembly of its core components before starting the heat energy conversion and utilization process. During assembly, the worker first inserts the main rod 402 of the metal rod assembly 4 into the conical mounting hole 301 on the sealing ring 3. Because both the mounting hole 301 and the sealing sleeve 302 are conical and the inner diameter of the opening near the collector tube 2 is smaller, the outer wall of the main rod 402 can form a tight interference fit with the inner conical surface of the sealing sleeve 302. This not only provides initial fixed support for the metal rod assembly 4 but also directly strengthens the sealing performance at the connection between the metal rod assembly 4 and the collector tube 2. Subsequently, when the main rod 402 is fully inserted into the mounting hole 301, the anode head 403 is fully inserted into the collector tube 2, and the rotating head 401 will also drive the locking rod 4013 to insert into the spring lock assembly. Inside the fixing ring 501 of component 5, the rotating head 401 is rotated to drive the locking rod 4013 to rotate. When the locking rod 4013 rotates to the locking hole 502, the locking spring 4012 will automatically pop out the locking rod 4013 and accurately lock it into the locking hole 502, thereby quickly completing the detachable fixed assembly of the metal rod assembly 4 and the sealing ring 3. Compared with the traditional bolt connection method, this process does not require additional tools, greatly shortening the assembly time and laying the foundation for convenient disassembly during subsequent maintenance. During this process, the sealing ring 304 and the conical structure in the annular sealing groove 303 on the inner wall of the sealing sleeve 302 can form a double sealing protection, thereby sealing the connection between the metal rod assembly 4 and the heat collection tube 2. This can prevent the fluid in the heat collection tube 2 from leaking from the connection and isolate external air and impurities from entering, avoiding heat loss or a decrease in heat collection efficiency due to sealing problems during subsequent operation. After the metal rod assembly 4 is installed, the solar collector enters the normal operation stage. When sunlight shines, the heat-absorbing coating on the surface of the solar collector tube 2 fully absorbs solar energy and quickly converts it into heat energy. The heat is transferred to the fluid to be heated stored inside the insulated water tank 1 through the connection between the solar collector tube 2 and the insulated water tank 1. At this time, multiple sets of arc-shaped flow-guiding protrusions evenly distributed along the axial direction on the inner wall of the insulated water tank 1 guide the fluid to form an orderly circulation flow, breaking the local uneven heating phenomenon that is prone to occur when the fluid is still. This allows all the fluid in the water tank to be evenly contacted with heat, significantly improving the overall heating efficiency and accelerating the fluid heating rate. At the same time, the tail frame 7 supports and positions the end of the solar collector tube 2 away from the insulated water tank 1 to ensure the stability of the solar collector tube 2 during operation. During continuous operation of the solar collector, the metal rod assembly 4 can provide corrosion protection for the solar collector tube 2 through sacrificial anode. The specific principle is as follows: the anode head 403 of the metal rod assembly 4 is made of metals such as zinc and magnesium, which have higher electrochemical activity than the metal material of the solar collector tube 2. When the anode head 403 comes into contact with the fluid inside the solar collector tube 2, a micro electrochemical battery is formed. Under electrochemical action, the more active anode head 403 will preferentially lose electrons and undergo oxidation corrosion reaction. As the cathode, the solar collector tube 2 avoids oxidation-reduction reaction with the corrosive medium in the fluid because electrons are preferentially provided by the anode head 403. This effectively blocks the corrosion process of the inner wall of the solar collector tube 2, slows down the aging rate of the solar collector tube 2, and significantly extends its service life. Finally, the insulated water tank 1 continuously keeps the heated fluid warm through its internal insulated cavity, reducing heat loss to the external environment and ensuring that the fluid can be maintained in the temperature range that meets the usage requirements for a long time. In addition, the support legs 8 at the bottom of the insulated water tank 1 and the tail frame 7 always provide stable installation support for the entire solar collector, ensuring the continuous and safe operation of the system.
