Description

Technical Field

[0001] This utility model relates to the field of pressurized water tank technology, and in particular to an integrated pressurized water tank for solar heating. Background Technology

[0002] ① To ensure pressure resistance, traditional solar pressurized water tanks often use a thickened inner tank wall to resist internal pressure by increasing the material thickness. However, the increased wall thickness directly leads to a significant increase in the overall weight of the tank, which not only increases the cost of raw materials but also requires additional load-bearing support during transportation and installation, especially in rooftop installation scenarios where the load-bearing capacity of the building structure may be limited. At the same time, the heavy tank is prone to structural stress due to its own weight during long-term use, which indirectly reduces the service life of the equipment.

[0003] ② To address the issue of heavy inner casings, some improvement solutions employ the design of adding concave or convex reinforcing ribs to the casing surface. By stamping regularly distributed recesses or bulges into the casing wall, the geometry of the reinforcing ribs alters the stress distribution path of the casing, effectively dispersing internal pressure loads. This structure can reduce wall thickness and overall weight under the same pressure requirements, while simultaneously improving the structure's resistance to deformation, such as reducing fatigue damage under cyclic thermal expansion and contraction conditions.

[0004] ③ Although concave or convex reinforcing ribs improve pressure resistance and weight reduction, the continuous concave-convex structure they form results in an irregular undulating surface on the enclosure. This structural characteristic directly causes the equipment to have a rough appearance and makes cleaning difficult, as scale easily accumulates in the recesses and is difficult to remove. At the same time, the concave-convex structure significantly increases the contact area between the enclosure and the ambient air, causing heat to dissipate to the outside through the metal wall at an accelerated rate, resulting in a significant reduction in thermal insulation performance. In essence, the concave-convex geometry on which weight reduction improvement depends becomes a double burden of sacrificing aesthetics and thermal efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated pressurized water tank for solar heating, which solves the problems of rough appearance and difficulty in cleaning caused by the uneven surface structure of concave or convex reinforcing ribs, as well as the decrease in heat preservation performance caused by the increase in heat dissipation area.

[0006] To achieve the above objectives, this utility model provides an integrated pressurized water tank for solar heating, comprising an integrally formed cylindrical inner tank. The inner tank has corrugated reinforcing ribs on its radially outer side. Transmission connectors are fixedly installed above and below the reinforcing ribs on the radially outer side of the inner tank. The transmission connectors can be connected to the input and output ends of the solar energy source via threads. The bottom end of the inner tank is concave upward and extends to form a connecting screw groove. Connecting connectors are welded and installed in four directions along the center point of the connecting screw groove at the bottom end of the inner tank. The connecting connectors can be connected to an external pressure relief valve, a pressure gauge, and a water inlet pipe via threads.

[0007] The inner box is welded to the outside of the outer casing. The outer casing is formed by welding a single piece of sheet metal. The weld seam of the outer casing allows the transmission connector to pass through.

[0008] Three pads are welded to the side of the outer casing away from the transmission connector. An assembly plate is welded to the side of the pads opposite to the outer casing. Assembly holes are opened on both sides of the assembly plate.

[0009] The outer casing has an upper cover welded to its top and a lower cover welded to its bottom. The lower cover is recessed inward and extends to form a through groove.

[0010] A connecting screw block runs through the through groove. The connecting screw block is threaded into the connecting screw groove so that the heating tube passes through the inside of the inner box. The heating tube is fixedly installed at one end of the connecting screw block.

[0011] A power cord is installed through the connecting screw block at one end opposite to the heating tube. The output end of the power cord is connected to the corresponding interface of the heating tube to realize the electric heating of the water source inside the inner box. The input end of the power cord is connected to an external power source.

[0012] This utility model discloses an integrated pressurized water tank for solar heating. Its core structure includes an integrally formed cylindrical inner tank. Corrugated tubular reinforcing ribs are directly formed on the radially outer side of the inner tank. This corrugated structure, through continuous concave-convex curved surface geometry, forms a self-supporting pressure-bearing frame on the inner tank wall, significantly improving its resistance to internal water pressure expansion and deformation. Simultaneously, the corrugated gaps naturally form a static air insulation layer, blocking the heat conduction path. Dual-path transmission connectors are fixedly installed above and below the radially outer side of the inner tank, respectively, and are threadedly and sealed to the medium output pipe and return pipe of the solar collector system. This allows for direct circulation of high-temperature medium into the inner tank to release heat, and guides cooling medium back to the collector system in a two-way closed-loop flow. The bottom of the inner tank is concave upwards to form a connecting screw groove. Multiple connecting joints are evenly welded around the center of this screw groove. These joints are independently connected to an external pressure relief valve via threads, enabling automatic unloading when pressure exceeds limits, continuous monitoring of the inner tank status by a pressure gauge, replenishment of cold water through the inlet pipe, and output of hot water through the drain pipe—all functions of a multi-functional integrated interface.

[0013] This structure achieves a dual technological breakthrough through the unique geometry of its corrugated tubular reinforcing ribs: its continuous curved surface evenly disperses the stress on the inner tank wall, significantly reducing the material thickness required for the same pressure bearing capacity; simultaneously, the static air enclosed within the corrugated gaps forms a highly efficient heat insulation barrier, making it difficult for heat to dissipate outwards through the metal tank, thus solving the persistent problem of heat loss caused by the increased exposed surface area of ​​traditional concave-convex reinforcing ribs; and the smooth transition surface of the corrugated structure avoids the defects of concave or convex structures that are prone to dirt accumulation and difficult to clean. The design of dual-path transmission joints running through the reinforcing ribs and directly into the inner tank cavity eliminates the heat loss nodes of traditional external piping. The process of high-temperature medium directly contacting the water for heating and cooling medium seamlessly returning to the collector achieves zero transition loss, greatly improving the solar thermal conversion efficiency. The coordinated design of the bottom connecting screw grooves and the surrounding interface group highly integrates pressure relief monitoring and fluid management functions. The pressure gauge and pressure relief valve form a dual overpressure protection mechanism, and the independent channels for the inlet and outlet pipes avoid disturbance between hot and cold water. The concave structure of the screw grooves compresses the overall height of the inner tank, providing a compact mounting base for the multi-functional interfaces.

[0014] During overall operation, the stress dispersion of the corrugated ribs and the heat preservation of the air gap work simultaneously, the efficient operation of the medium direct heat exchange path, and the real-time monitoring of the bottom safety center, the three core modules work together to solve the inherent contradiction between pressure strength, heat retention performance, lightweight and aesthetics without external assistance, so as to achieve the long-term reliable operation of the solar heating system under complex working conditions.

[0022] Please see Figures 1-4 .

[0023] This utility model provides an integrated pressurized water tank for solar heating. The core component of the tank includes an integrally formed cylindrical inner tank 101. Corrugated reinforcing ribs 102 are directly formed or welded to the radial outer side of the inner tank 101. This structure significantly improves the overall pressure resistance of the inner tank 101 and forms an air insulation layer to enhance heat preservation. Transmission connectors 103 are fixedly installed above and below the reinforcing ribs 102 on the radial outer side of the inner tank 101. These transmission connectors 103 are used to connect the medium inflow and outflow pipes of the solar energy system via threads, realizing heat input and hot water output. A connecting threaded groove 104 is formed by an upwardly recessed groove at the center of the bottom of the inner tank 101. Multiple connecting joints 105 are evenly welded around the center point of the connecting groove 104 along the circumferential direction. These connecting joints 105 are respectively connected to an external pressure relief valve for pressure safety protection, a pressure gauge for real-time monitoring of the pressure of the inner tank 101, a water inlet pipe for cold water replenishment, and a drainage pipe for hot water discharge. To protect the inner tank 101 and improve aesthetics, an outer protective sleeve 106, formed by rolling and welding a single piece of metal sheet, is integrally welded to the outside of the inner tank 101 and the reinforcing rib 102. The weld seam of the outer protective sleeve 106 needs to be precisely machined to allow the transmission joint 103 to extend through. This overcomes the disadvantages of the traditional thick-walled cylinder being heavy or the concave reinforcing rib 102 affecting the appearance. Three parallel pads 107 are welded and fixed to the outer wall of the outer casing 106 on the side opposite to the transmission connector 103. An assembly plate 108 is welded to the outer end of each pad 107 facing outward. Assembly holes 109 are provided on both sides of each assembly plate 108 to facilitate the fixing of the entire water tank in the installation position. The top end of the outer casing 106 is welded and sealed with an upper cover 110, and the bottom end is welded with a lower cover 111 with a specific structure. The lower cover 111 extends inward to form a through groove 112 coaxial with the bottom of the inner tank 101. A connecting screw block 113 is installed through the through groove 112 and is fastened to the connecting screw groove 104 at the bottom of the inner tank 101 by threads. Ensuring mechanical strength and sealing; a heating tube 114 is fixedly installed inside the water tank through the connecting screw block 113, and the heating tube 114 is immersed in water to provide auxiliary electric heating; the other end of the connecting screw block 113 opposite to the heating tube 114 leads out a power line 115, the output end of the power line 115 is deeply inserted into the interior and reliably connected to the corresponding electrical interface of the heating tube 114, and its input end is reserved for external connection to the power supply line, so as to start electric heating of the internal water source when needed; the whole structure, through the precise assembly and spatial coordination of the above components, realizes the integration of functions such as pressurized heat storage, dual-source heating (solar energy priority, electric auxiliary supplement), safety monitoring (pressure relief, pressure measurement) and convenient installation.

[0024] Working principle: First, the coils of the solar energy system are placed inside the inner tank 101. Then, the heated medium is introduced into the coils in the inner tank 101 through the transmission connector 103. This medium circulates inside the inner tank 101 and transfers heat, gradually raising the temperature of the water stored in the inner tank 101. At the same time, the electric auxiliary heating system provides supplementary heat energy through the heating pipe 114 when needed to ensure stable water temperature. The corrugated tubular reinforcing ribs 102 of the inner tank 101 play a significant role in pressure-bearing environments, enhancing the overall durability of the inner tank 101. The inner tank 101 is pressurized to prevent deformation caused by pressure fluctuations. The corrugated structure of the reinforcing rib 102 forms an air insulation layer, improving insulation, reducing heat loss, and optimizing energy efficiency. Once the water is heated, the inner tank 101 stores the hot water under pressure and outputs it to the heating or heating terminal equipment via the connecting joint 105 after connecting to the drainage pipe. During this process, the inlet pipe replenishes water through the connecting joint 105. The pressure relief valve and pressure gauge monitor the pressure in the inner tank 101 in real time and automatically adjust the pressure relief to prevent overpressure risks. This reflects… The connecting joint 105 provides a coordinated function; the heating tube 114 is located inside the inner box 101 and is connected to an external power source via the power cord 115 to achieve electric heating, complementing solar heating and ensuring continuous operation of heating around the clock; structurally, the outer casing 106 is welded to wrap around the inner box 101, providing mechanical protection and aesthetic appeal. Compared to the weight and unsightly appearance caused by the thick cylinder wall or concave reinforcing ribs 102 in traditional technologies, this solution is lightweight and aesthetically pleasing; the transmission joint 103 connects both the input and output ends, working in conjunction with the heating tube 114 to achieve heating circulation; the outer casing 106, combined with the cover, protects the inner box 101 and the heating components, while the pad rod 107 and assembly plate 108 facilitate installation and fixation; the corrugated reinforcing ribs 102 and the outer casing 106 together improve structural stability and reduce energy loss, while the connecting bolt 113 ensures that the heating tube 114 is sealed and penetrated to prevent leakage; in this way, the components work seamlessly together to achieve efficient, safe, and long-lasting solar heating, reducing maintenance costs and improving the user experience.
