Description
Technical Field
[0001] This utility model belongs to the field of solar water heater technology, specifically relating to a sealing structure for a solar water heater storage tank. Background Technology
[0002] Currently, due to their significant energy-saving and environmentally friendly effects, solar water heaters are being used more and more widely. A solar water heater is a device that converts solar energy into heat energy, heating water from a low temperature to a high temperature to meet people's hot water needs in daily life and production. Solar water heaters are classified into vacuum tube solar water heaters and flat-plate solar water heaters according to their structure, with vacuum tube solar water heaters being the dominant type, accounting for 95% of the domestic market share. A vacuum tube household solar water heater consists of collector tubes, a water tank, and supporting components. The conversion of solar energy into heat energy mainly relies on the vacuum collector tubes. The vacuum collector tubes utilize the principle that hot water rises and cold water sinks, creating a micro-circulation of water to achieve the desired hot water temperature. Most existing solar water heaters have the water tank located inside the outer shell for protection; however, after prolonged use, the tank may become damaged, making it difficult for repair workers to disassemble and inspect the internal condition, thus affecting the repair results.
[0003] Therefore, a water tank structure for a solar water heater, with announcement number "CN215864106U", is described. The upper shell is located above the lower shell, the water tank body is placed inside the lower shell, a snap-fit assembly is located on the side of the lower shell, and a sealing assembly is located on the inner wall of the lower shell. The upper and lower shells are movably connected. With the water tank body placed inside the lower shell and the snap-fit assembly on the side of the lower shell, the upper and lower shells are snapped together. Through the snap-fit assembly, the upper shell can be opened from the lower shell, allowing maintenance personnel to easily inspect and repair the water tank body inside the lower shell, thus improving maintenance efficiency.
[0004] However, for the water tank structure of the above-mentioned solar water heater, although the reset block above the spring is raised, the reset block will raise the retaining block, and the fixing block is set on the side of the upper shell to support the retaining block. When the retaining block is raised, the fixed block that is fixedly connected will be raised, and the upper shell will open from the lower shell. However, there are still some obvious defects in the use of the above-mentioned water tank structure: the water tank of the above-mentioned water tank structure is sealed inside by two semi-circular shells. During disassembly and maintenance, because the surface of the water tank is smooth, it is not possible to easily lift the water tank out of the semi-circular shell for maintenance. In addition, the gap between the water tank and the semi-circular shell is small, and tools cannot be inserted for disassembly and assembly. Utility Model Content
[0005] The purpose of this utility model is to provide a sealing structure for a solar water heater storage tank to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a solar water heater storage tank, comprising:
[0007] The water storage tank has an arc-shaped elastic retaining ring on its exterior via a limiting slot for locking and fixing the water storage tank.

[0008] A semi-circular sealing shell A is connected to a semi-circular sealing shell B, which seals and covers the water storage tank, via an embedded hinge on one end of the semi-circular sealing shell A. The semi-circular sealing shell A is slidably disposed outside the semi-circular assembly slide plate. After the semi-circular sealing shell A and the semi-circular sealing shell B seal and cover the water storage tank, their two ends are screwed with side sealing screw caps that tighten and seal the two ends of the water storage tank.
[0009] Preferably, the limiting groove is integrally formed and recessed at both ends of the water tank surface, and the arc elastic retaining ring is engaged inside the limiting groove to fix the water tank on the inner side of the semi-circular assembly slide plate, which can stably fix the water tank on the inner side of the semi-circular assembly slide plate and ensure the stability of the water tank position within the semi-circular assembly slide plate.
[0010] Preferably, the outer surface of the semi-circular assembly slide plate is provided with strip-shaped sliders on both sides to allow the water tank to slide out of the semi-circular sealing shell A and the semi-circular sealing shell B during disassembly and assembly.
[0011] Preferably, the inner wall of the semi-circular sealing shell A is provided with strip grooves on both sides, and the semi-circular assembly slide plate allows the water tank to slide and be disassembled on the semi-circular sealing shell A through the cooperation of the strip slider and the strip groove. This allows the water tank to slide out of the semi-circular sealing shell A and the semi-circular sealing shell B more smoothly during disassembly and assembly, reducing the difficulty of disassembly and assembly and improving the convenience of operation.
[0012] Preferably, the side sealing screw cap is threadedly sealed at both ends after the semi-circular sealing shell A and the semi-circular sealing shell B are sealed together, and the side sealing screw cap is provided with a rubber top plate inside to seal and tighten the two ends of the water tank, which ensures the smoothness and stability of the water tank sliding in the semi-circular sealing shell A, making the disassembly and assembly of the water tank more convenient and efficient, and improving the work efficiency of maintenance.
[0013] Preferably, one end of the side sealing screw cap is provided with a rubber sealing collar, and the rubber sealing collar is sealed and fitted to both ends of the surfaces of the semi-circular sealing shell A and the semi-circular sealing shell B after the side sealing screw cap is threaded and sealed. The side sealing screw cap is threaded and sealed at both ends, which can effectively seal both ends of the water storage tank. The internal rubber top plate seals and tightens the two ends of the water storage tank, which enhances the sealing effect, prevents water from leaking from both ends of the water storage tank, and ensures the sealing performance and safety of the solar water heater water storage tank.
[0014] Preferably, the embedded grooves are provided on one side of the surface of the semicircular sealing shell A and the semicircular sealing shell B respectively. The two ends of the embedded hinge are fixed in the embedded grooves by screws so that the semicircular sealing shell A and the semicircular sealing shell B can be sealed together. This connection method not only ensures the connection strength between the two, but also facilitates opening and closing, and makes it convenient for the water storage tank to be inspected and maintained.

The inner wall of the semicircular sealing shell B is provided with a sealing strip that fits and seals against the semicircular mounting plate. The through-hole slots facilitate the passage of water inlet / outlet pipes and overflow pipes, meeting the functional requirements of the solar water heater. The sealing rubber rings ensure the sealing of the water pipe passage points and prevent water leakage. The sealing strip on the inner wall of the semicircular sealing shell B fits and seals against the semicircular mounting plate, further enhancing the sealing effect.
[0016] Compared with the prior art, the technical effects and advantages of this utility model are: the sealing structure of the solar water heater storage tank,

The outer surface of the semi-circular assembly slide plate is equipped with a strip-shaped slider, and the inner wall of the semi-circular sealing shell A is equipped with a strip-shaped groove. The strip-shaped slider and the strip-shaped groove cooperate to allow the water storage tank to slide out of the semi-circular sealing shell A and the semi-circular sealing shell B more smoothly during disassembly and assembly. This solves the problem that existing water tanks are difficult to lift out of the semi-circular shell due to their smooth surface and the small gap that makes it impossible to insert tools for disassembly and assembly. It reduces the difficulty of disassembly and assembly, and improves the convenience of operation and the efficiency of maintenance work.
[0018] The side-sealing screw caps are threaded and sealed at both ends of the semi-circular sealing shells A and B after they are sealed together. An internal rubber top plate seals and tightens the seal at both ends of the water tank.

These designs ensure the sealing of all parts of the water tank, preventing water leakage and ensuring the airtightness and safety of the solar water heater's water tank.
[0019] The circular sealing shell A and the semi-circular sealing shell B are connected by an embedded hinge. The two ends of the embedded hinge are fixed in the inner groove. This connection method not only ensures the connection strength between the two, but also facilitates opening and closing, making it convenient for inspection and maintenance of the water tank. At the same time, the limiting groove is integrally formed and recessed, and the arc elastic retaining ring is engaged in the limiting groove, which can firmly engage and fix the water tank on the inner side of the semi-circular assembly slide plate, ensuring the stability of the water tank's position within the semi-circular assembly slide plate and making the entire structure reliable.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 This utility model provides a technical solution: a sealing structure for a solar water heater storage tank, comprising:
[0028] The water storage tank 1 has an arc-shaped elastic retaining ring 3 on its exterior, which is provided by a limiting groove 2 for locking and fixing the water storage tank 1. The limiting groove 2 is directly engaged with the arc-shaped elastic retaining ring 3. Through a tight fit, the water storage tank 1 is tightly connected to the semi-circular assembly slide plate 4. The arc-shaped elastic retaining ring 3 is fixed with a semi-circular assembly slide plate 4, which is a semi-circular structure for sliding out and sealing assembly of the water storage tank 1. The limiting groove 2 is integrally formed at both ends of the water storage tank 1 and is used to connect with the arc-shaped elastic retaining ring 3. This securely locks and fixes the water storage tank 1 to the inside of the semi-circular assembly slide plate 4, ensuring the stability of the position of the water storage tank 1 during the operation of the entire system. One end of the arc-shaped elastic retaining ring 3 is engaged in the limiting groove 2 of the water storage tank 1, and the other end is fixed to the semi-circular assembly slide plate 4, which serves as a bridge connecting the water storage tank 1 and the semi-circular assembly slide plate 4.
[0029] The water tank 1 is connected to the water storage tank 1 by an arc-shaped elastic retaining ring 3, and the strip-shaped slider 9 on its outer surface is slidably connected to the strip groove 10 on the inner wall of the semi-circular sealing shell A5, thereby realizing the sliding function of the water storage tank 1 within the semi-circular sealing shell A5.
[0030] A semi-circular sealing shell A5 is movably connected to a semi-circular sealing shell B7 at one end via an embedded hinge 6. Its inner wall has strip grooves 10 on both sides, which cooperate with the strip sliders 9 of the semi-circular mounting plate 4 to guide the sliding of the water storage tank 1. Made of [high-strength sealing material name], it possesses excellent sealing performance and structural strength, effectively protecting the water storage tank 1 and preventing leakage. Together with the semi-circular sealing shell B7, it forms a sealed space, sealing the water storage tank 1 internally to ensure no hot water leakage. One end is connected to the semi-circular sealing shell B7 via the embedded hinge 6, allowing it to rotate around the hinge to open and close with the semi-circular sealing shell B7. The strip grooves 10 on its inner wall are slidably connected to the strip sliders 9 of the semi-circular mounting plate 4, and the exterior is threadedly connected to the side sealing cap 8 to seal one end of the water storage tank 1.
[0031] A semi-circular sealing shell A5 is movably connected to a semi-circular sealing shell B7, which seals the water tank 1, via an embedded hinge 6. B7 works in conjunction with A5 to seal the water tank 1. A sealing strip 15 is provided on its inner wall, fitting snugly against the semi-circular mounting slide plate 4 to further enhance the overall sealing performance. Also made of [high-strength sealing material name], it works in conjunction with A5 to ensure the sealing effect of the water tank 1 and prevent hot water leakage. A5 is slidably positioned outside the semi-circular mounting slide plate 4.
[0032] After the semi-circular sealing shells A5 and B7 are sealed and closed to the water storage tank 1, their two ends are screwed with side sealing caps 8 to tighten and seal the two ends of the water storage tank 1. The threads seal the two ends of the semi-circular sealing shells A5 and B7 after they are sealed and closed. An internal rubber top plate 11 is provided for sealing and tightening the two ends of the water storage tank 1; a rubber sealing collar 12 is provided at one end, which, after the thread seal, seals and adheres to the two ends of the surfaces of the semi-circular sealing shells A5 and B7. Made of [corrosion-resistant metal material], it ensures that the sealing performance will not be affected by corrosion during long-term use. The two ends of the semi-circular sealing shells A5 and B7 are sealed by tightening the threads, while the rubber top plate 11 and rubber sealing collar 12 further enhance the sealing effect. A locking assembly is provided on the other side of the combined semi-circular sealing shells A5 and B7.
[0033] The limiting groove 2 is integrally formed and recessed at both ends of the surface of the water tank 1, and the arc-shaped elastic retaining ring 3 engages inside the limiting groove 2 to fix the water tank 1 inside the semi-circular assembly slide plate 4. The outer surface of the semi-circular assembly slide plate 4 has strip-shaped sliders 9 on both sides, allowing the water tank to slide out of the semi-circular sealing shell A5 and semi-circular sealing shell B7 during assembly and disassembly. These sliders are located inside the side sealing screw cap 8 and have good elasticity and sealing performance. When the side sealing screw cap 8 is tightened, the rubber top plate 11 tightly presses against both ends of the water tank 1, effectively preventing water leakage from both ends of the water tank 1 and improving the sealing effect. Through its own elastic deformation, it tightly fits both ends of the water tank 1, filling any possible gaps and achieving a good seal.
[0034] The inner wall of the semi-circular sealing shell A5 has strip grooves 10 on both sides, which are installed at one end of the side sealing cap 8. After the side sealing cap 8 is threaded and sealed, the rubber sealing ring 12 fits tightly against both ends of the surfaces of the semi-circular sealing shell A5 and the semi-circular sealing shell B7, further enhancing the sealing effect and reducing the possibility of leakage. By fitting tightly against the surfaces of the semi-circular sealing shell A5 and the semi-circular sealing shell B7, water is prevented from leaking from the connection between the side sealing cap 8 and the semi-circular sealing shell.
[0035] The semi-circular assembly slide plate 4, through the cooperation of the strip slider 9 and the strip groove 10, allows the water tank 1 to slide within the semi-circular sealing shell A5 for assembly and disassembly. The strip slider 9, in conjunction with the strip groove 10 on the inner wall of the semi-circular sealing shell A5, enables smooth sliding of the water tank 1 within the shell, greatly facilitating its disassembly, assembly, and maintenance. Simultaneously, it provides a sliding carrier for the water tank 1, allowing it to be installed and removed within the sealed space formed by the semi-circular sealing shell A5 and the semi-circular sealing shell B7.
[0036] The side sealing cap 8 is threaded and seals both ends of the semi-circular sealing shell A5 and the semi-circular sealing shell B7 after they are sealed together. Inside the side sealing cap 8 is a rubber top plate 11 that tightly seals and presses against both ends of the water storage tank 1. Located inside the side sealing cap 8, it has good elasticity and sealing performance. When the side sealing cap 8 is tightened, the rubber top plate 11 tightly presses against both ends of the water storage tank 1, effectively preventing water leakage from both ends of the water storage tank 1 and improving the sealing effect. Through its own elastic deformation, it tightly fits against both ends of the water storage tank 1, filling any possible gaps and achieving a good seal.
[0037] A rubber sealing collar 12 is provided at one end of the side sealing screw cap 8. After the side sealing screw cap 8 is threaded and sealed, the rubber sealing collar 12 is tightly fitted to both ends of the surfaces of the semi-circular sealing shell A5 and the semi-circular sealing shell B7, and is installed at one end of the side sealing screw cap 8. After the side sealing screw cap 8 is threaded and sealed, the rubber sealing collar 12 is tightly fitted to both ends of the surfaces of the semi-circular sealing shell A5 and the semi-circular sealing shell B7, further enhancing the sealing effect and reducing the possibility of leakage. By tightly fitting to the surfaces of the semi-circular sealing shell A5 and the semi-circular sealing shell B7, water is prevented from leaking from the connection between the side sealing screw cap 8 and the semi-circular sealing shell.
[0038] The two ends of the embedded hinge 6 are fixed in the embedded groove 13 on one side of the surface of the semi-circular sealing shell A5 and the semi-circular sealing shell B7 respectively, so that the semi-circular sealing shell A5 and the semi-circular sealing shell B7 are sealed and covered.
[0039] The side sealing cap 8 at one end of both the semi-circular sealing shell A5 and the semi-circular sealing shell B7 has multiple through-hole slots 14 for easy passage of water inlet / outlet pipes and overflow pipes. Each through-hole slot 14 contains a sealing ring. The inner wall of the semi-circular sealing shell B7 has a sealing strip 15 that fits snugly against the semi-circular mounting slide plate 4. Made of [sealing rubber material name], it possesses good flexibility and sealing properties, further enhancing the sealing effect between the semi-circular sealing shell B7 and the semi-circular mounting slide plate 4, preventing water leakage. By fitting snugly against the semi-circular mounting slide plate 4, it fills any gaps between them, enhancing the overall sealing performance of the sealing structure.
[0040] Specifically, during use, the water tank 1 has concave limiting grooves 2 integrally formed at both ends of its surface. An arc-shaped elastic retaining ring 3 engages within the limiting grooves 2, thus securing the water tank 1 to the inner side of the semi-circular assembly slide plate 4. This ensures a stable connection between the water tank 1 and the semi-circular assembly slide plate 4, guaranteeing the stability of the water tank 1's position within the semi-circular assembly slide plate 4 and laying the foundation for subsequent sealing and use. The outer surface of the semi-circular assembly slide plate 4 has strip-shaped sliders 9 on both sides, and the inner wall of the semi-circular sealing shell A5 has strip-shaped grooves 10 on both sides. Through the cooperation of the strip-shaped sliders 9 and the strip-shaped grooves 10, the semi-circular sealing shell A5 can slide outside the semi-circular assembly slide plate 4. One end of the semi-circular sealing shell A5 is movably connected to the semi-circular sealing shell B7 via an embedded hinge 6. When sealing the water tank 1 is required, the semi-circular sealing shell B7 rotates around the embedded hinge 6 to cover the semi-circular sealing shell A5, thereby sealing the water tank 1 internally.
[0041] After the semi-circular sealing shells A5 and B7 seal the water storage tank 1, side sealing caps 8 are screwed onto both ends. The rubber top plate 11 inside the side sealing cap 8 can seal and tighten both ends of the water storage tank 1. At the same time, the rubber sealing collar 12 at one end of the side sealing cap 8 will seal and fit against both ends of the surface of the semi-circular sealing shells A5 and B7 after the thread seal, achieving effective sealing and positioning of both ends of the water storage tank 1 and preventing water leakage. A through hole groove 14 is opened on the surface of the side sealing cap 8 at one end of the semi-circular sealing shells A5 and B7 to facilitate water inlet and outlet. The water pipe and overflow pipe protrude through the through-hole groove 14, which is equipped with a sealing ring to ensure the sealing of the water pipe protrusion and prevent water leakage from this part. When maintenance is required on the water storage tank 1, the strip slider 9 of the semi-circular mounting slide plate 4 cooperates with the strip groove 10 of the semi-circular sealing shell A5, allowing the water storage tank 1 to slide smoothly within the semi-circular sealing shell A5. By sliding the water storage tank 1, it can slide out of the semi-circular sealing shell A5 and the semi-circular sealing shell B7, solving the problem that existing water tanks are difficult to lift out of the semi-circular shell due to their smooth surface and the small gap that makes it difficult to insert tools for disassembly and assembly, thus facilitating maintenance operations. At the same time, the semi-circular sealing shell A5 and the semi-circular sealing shell B7 are connected by an embedded hinge 6, which facilitates opening and closing, further facilitating the maintenance and repair of the water storage tank 1.
