Description

Technical Field

[0001] The present application relates to the technical field of secondary water supply, and in particular to a secondary water supply storage device. Background Art

[0002] As an important supplemental water supply method for cities, secondary water supply systems play an irreplaceable role in high-rise building water supply. Due to limited municipal water supply pressure, secondary water supply ensures a stable water supply for high-rise buildings by increasing pressure and storage systems, significantly improving the quality of life for urban residents. However, with the widespread use of secondary water supply systems, water quality safety issues have become increasingly prominent, especially water pollution, which has become a major challenge facing secondary water supply systems. To address water pollution, existing technologies generally use various methods to improve secondary water supply equipment. Common methods include installing a vent cap that connects to the atmosphere to ensure pressure balance in the container; using a sealed air pressure tank to isolate the water from external air to prevent water contamination; or installing a filter in the water tank to filter the air inside the tank and reduce the entry of impurities from the air. In addition, some systems install filters or filtration devices on the inlet and outlet pipes to directly prevent impurities from entering the water storage system. While the above-mentioned methods have helped improve the water quality safety of secondary water supply systems to a certain extent, conventional secondary water supply storage equipment lacks a simple, water-isolating device that effectively prevents water contamination within the storage tank. For example, while existing pressure tanks can partially isolate air, air can still enter the water due to pressure differential fluctuations, causing hypochlorous acid to come into contact with air and deteriorate water quality. This limits the efficiency and reliability of existing methods in field applications. Utility Model Content

[0010] The following will be combined with the Figure 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described. The embodiments described are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0011] The embodiment of the present application provides a secondary water supply and storage device, referring to Figure 1 and Figure 2 The secondary water supply and storage device includes a water tank 1, with water inlet and outlet pipes 11 disposed at the bottom and an air inlet pipe 12 fixedly connected to the top. A piston assembly 2 is installed within the tank 1 to separate air from the water. The inner diameter of the piston assembly 2 abuts the inner wall of the tank 1, allowing it to slide within the tank 1 as the water level rises and falls. This design effectively isolates air from water, preventing air from entering the water due to pressure differentials and deteriorating water quality.

[0012] Reference Figure 2 and Figure 3 The piston assembly 2 includes a positioning plate 21, a pressure plate 22 and a positioning ring 23. The pressure plate 22 is located at the bottom of the positioning plate 21, and the positioning ring 23 is used to connect the positioning plate 21 and the pressure plate 22. A closed cavity 24 is formed between the positioning plate 21, the pressure plate 22 and the positioning ring 23. In order to improve the sealing effect and adapt to different environmental conditions, the pressure plate 22 and the positioning ring 23 are both made of elastic materials, such as silicone materials or rubber materials. In practical applications, other elastic materials such as neoprene, natural rubber, etc. can also be used. When the water pressure changes, the pressure plate 22 and the positioning ring 23 are deformed, squeezing the cavity 24 to make it fit more tightly with the inner wall of the water tank 1, effectively improving the sealing performance, thereby reducing the possibility of air entering the water.

[0013] Specifically, an arc-shaped rubber pad 25 is provided outside the positioning ring 23, forming a sealed cavity 26 between the rubber pad 25 and the positioning ring 23. When the positioning ring 23 deforms due to changes in water pressure, this deformation pushes the rubber pad 25 closer against the inner wall of the water tank 1, further enhancing the sealing effect. The rubber pad 25 itself also has a certain degree of elasticity, so it can adapt to changes in the inner wall of the water tank 1 during use, ensuring long-term stable sealing performance. The rubber pad 25 can also be made of a variety of materials, such as silicone, natural rubber, or other materials with good elasticity, to adapt to the needs of use in different environmental conditions.

[0014] The working principle of this embodiment is as follows: the design of piston assembly 2 not only simplifies the complex sealing structure of the prior art, but also significantly enhances the sealing effect through the use of elastic materials, making it suitable for a variety of environmental conditions. The sliding of piston assembly 2 in response to changes in water level separates the air and water inside water tank 1, reducing direct contact between air and hypochlorous acid in the water. Furthermore, the presence of elastic material gives piston assembly 2 excellent deformability, adapting to pressure changes in different environments. This improves the reliability and stability of the overall device, significantly improving water quality and safety, and meeting the needs of users.

[0015] Example 2

[0016] Reference Figure 2 and Figure 4 This embodiment differs from the previous embodiment in that a filter assembly is provided on the air intake pipe 12 to further purify the air entering the water tank. This filter assembly includes a filter element 121, which is used to filter impurities from the air entering the water tank. Filter element 121 is bolted to the air intake pipe 12, making it easy to install and remove, clean, and replace.

[0017] Specifically, the filter element 121 includes multiple filter layers, which can effectively remove impurities such as dust and particles in the air and purify the air entering the water tank. In order to improve the filtering effect, a microporous filter material, such as meltblown cloth, is provided inside the filter element 121, which has a high filtering efficiency and can effectively capture fine particles in the air. In addition, the outer shell of the filter element 121 is made of high-strength materials, such as stainless steel or engineering plastics, to ensure its structural strength and corrosion resistance, and to maintain good filtering performance during long-term operation. The filter element 121 is installed by fixing it to the air intake pipe 12 with bolts to ensure a stable installation and facilitate subsequent replacement and cleaning.

[0018] The principle behind this embodiment is that by adding a filter assembly to the intake pipe 12, the quality of air entering the water tank can be further improved, reducing water contamination caused by airborne impurities. The design of the filter element 121 not only ensures excellent filtration but also facilitates maintenance and replacement, ensuring long-term stable operation of the secondary water supply and storage system and improving water quality safety.

[0019] Example 3

[0020] Reference Figure 2 and Figure 4 This embodiment differs from the previous embodiment in that multiple baffles 122 are installed within the air intake pipe 12. Each baffle 122 is tilted downward, primarily to block water vapor from the air and reduce its ingress into the water tank 1. This design effectively prevents excessive moisture from entering the water tank 1, reducing potential water contamination in the secondary water supply system.

[0021] Specifically, the baffles 122 within the air intake pipe 12 are multiple pieces, typically made of metal materials such as stainless steel or aluminum alloy. Each baffle 122 is tilted downward, effectively intercepting water vapor in the air, thereby reducing the amount of water vapor entering the water tank 1. These baffles 122 are fixed to the interior of the air intake pipe 12 by welding or snapping, ensuring structural stability and high interception efficiency. The specific number of baffles 122 can be adjusted according to actual needs to meet different usage scenarios. In actual applications, other materials with good diversion effects, such as high-strength composite materials, can also be used to meet the usage requirements in different environments.

[0022] The principle behind this embodiment is that by providing a downwardly angled baffle 122 within the air intake pipe 12, it effectively reduces the amount of water vapor in the air that enters the water storage tank 1, thereby reducing the risk of water contamination. The design of multiple baffles 122 not only ensures high interception efficiency but also structural stability and ease of installation, enhancing the practicality and stability of the overall device and further improving water quality safety.

[0023] Example 4

[0024] Reference Figure 1 The difference between this embodiment and the above-mentioned embodiment is that an accumulator 3 is provided on the inlet and outlet water pipes 11. The accumulator 3 is used to stabilize the pressure fluctuations in the water supply system. The accumulator 3 is provided on the inlet and outlet water pipes 11 to effectively absorb the water hammer effect and balance the instantaneous pressure drop in the water supply system, preventing excessive pressure in the system from causing pipeline fatigue. The accumulator 3 is generally made of high-strength materials, such as alloy steel or high-strength composite materials, to ensure its pressure-bearing capacity. In actual applications, the volume and pressure level of the accumulator 3 can be selected according to specific needs to ensure its stable operation under different usage conditions.

[0025] The operating principle of this embodiment is as follows: by installing an accumulator 3 on the inlet and outlet pipes 11, pressure fluctuations in the water supply system can be effectively balanced, preventing pipe fatigue and water pollution caused by excessive pressure. The design of accumulator 3 not only improves the reliability and stability of the entire device, but also extends the system's service life, ensuring the efficient operation of the secondary water supply system. The overall technical solution is not only structurally simpler, but also improves performance through cross-disciplinary innovative design, significantly improving the water quality and safety of the secondary water supply system.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
