Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of antifreeze of water supply systems, in particular to an energy-saving water-use pressurizing system. Background Art
[0002] In plateau areas, due to long water supply pipelines, low temperatures, and long winters, the tap water supply system often faces problems such as low water pressure, insufficient water volume, and easy freezing at water points. This makes it impossible to guarantee safe water supply at each water point, and therefore there is an urgent need to improve the water supply system. Currently, a water storage tank can be added to the pump station to lead to a booster pump to increase the water pressure to the corresponding boost value for the scenario, and a pressure tank can be installed at the outlet of the booster pump. The pressure tank capacity is proportional to the number of use points to ensure the water pressure impact at each use point. In terms of anti-freeze, electric heating cables are usually used to prevent ice from forming in the water storage tank. Electric heating cables have high energy consumption and can be used in areas with sufficient power supply. However, in some remote areas where power supply is insufficient, low-energy consumption measures are needed to complete the anti-freeze of the pump station water storage tank. Utility Model Content
[0003] In view of the problem that existing technical solutions require low-energy-consumption water tank anti-freezing measures in remote and cold areas, the utility model provides an energy-saving water boosting system.

[0005] Preferably, the outer tube is a stainless steel tube, and the inner tube is a metal bellows tube.
[0006] Preferably, the outer wall of the inner tube is further provided with a tube clamp, and a plurality of the tube clamps are arranged in sequence along the length direction of the inner tube.
[0007] Preferably, the phase change thermal storage material is paraffin.
[0008] Preferably, an inner tube is also provided inside the return pipe, and both ends of the inner tube are closed and filled with phase change heat storage material.
[0009] The beneficial effects of the utility model are as follows: the solar energy is converted into thermal energy by the solar water heater, and a circulating water heat exchange system is formed to transfer the heat to the water in the water tank; at the same time, the phase change thermal storage material is used to store heat; when there is no sunlight radiation, the phase change thermal storage material releases heat to the circulating water and the water in the water tank; the power supply only needs to maintain the normal operation of the circulating pump, which greatly reduces the energy consumption compared with the existing technology; the circulating water does not directly contact the water in the water tank, and there are two layers of protection between the phase change thermal storage material and the water in the water tank, so the risk of leakage is small, thereby ensuring the safety of water use.

DETAILED DESCRIPTION
[0013] The following is a more detailed description of the embodiments of the present invention with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the invention after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0014] The utility model provides Figure 1-2 The energy-saving water boosting system shown includes a water tank 10, a booster pump 20, and a pressure tank 30. The water tank 10 is provided with an inlet pipe 11, which is connected to a submersible pump in a pipe well. The water tank 10 is connected to the booster pump 20 via a connecting pipe. The outlet of the booster pump 20 is connected to a water supply pipe 21 extending to various water use points. The booster pump 20 can effectively increase the water pressure in the water supply pipe 21, and the water tank 10 acts as a buffer to prevent the booster pump 20 from idling. The bottom of the pressure tank 30 is connected to the outlet of the booster pump 20. The pressure tank 30 is sealed. When the valve at the water use point is closed, the water in the water supply pipe 21 enters the pressure tank 30 under the pressure of the booster pump, causing the water level inside to rise, compressing the air until pressure equilibrium is reached. When the valve at the water use point is opened, the compressed air and high water level in the pressure tank 30 boost the water supply pipe 21. The volume of the pressure tank 30 is proportional to the number of water use points, and it is ensured that the water supply pipe 21 is always full of water.
[0015] As altitude increases, air, dust, and moisture gradually decrease. Plateau regions offer high atmospheric transparency, strong direct solar radiation, extensive direct sunlight, and long sunshine hours, resulting in abundant solar energy resources. Therefore, in situations of insufficient power supply, solar energy resources should be fully utilized to prevent freezing of pump station water supply lines. To prevent freezing of water supply lines at low temperatures, particularly within water storage tanks, the present invention also includes a circulating heat exchanger.
[0016] The circulating heat exchange device includes a solar water heater, which includes a water tank 41. The water outlet of the water tank 41 is connected to a heat exchange tube 42, which is disposed within the water storage tank 10. The heat exchange tube 42 is connected to a circulation pump 43, which is connected to the water inlet of the water tank 41 via a return pipe 44. During the day, the solar water heater converts solar energy into heat energy to heat the circulating water in the water tank. Under the action of the circulation pump 43, the heated circulating water circulates within the water tank, the heat exchange tube, and the return pipe, bringing heat to the water in the water storage tank. Specifically, the solar water heater can be a flat-plate solar water heater, in which the water tank 41 is disposed on top of the water storage tank 10; the heat exchange tube 42 is a serpentine tube or a spiral tube to enhance the heat exchange effect.
[0017] The heat exchange tube 42 includes an outer tube 421 and an inner tube 422 disposed within the outer tube 421. The outer tube 421 is connected to the water tank 41 and the circulating pump 43 at both ends, respectively. The inner tube 422 is sealed at both ends and filled with a phase-change thermal storage material 423. Circulating water flows between the outer tube 421 and the inner tube 422. During normal daytime operation of the solar water heater, the heat of the circulating water is transferred not only to the water in the water tank 10 but also to the phase-change thermal storage material 423, causing it to undergo a phase change and store heat. At night or when there is no sunlight, the phase-change thermal storage material 423 releases heat to the circulating water and transfers it to the water in the water tank 10, preventing freezing. Furthermore, the phase-change thermal storage material 423 and the water in the water tank 10 are protected by two layers of protection, the outer tube and the inner tube. Even if the inner tube is damaged, it will not directly contaminate the water, ensuring water safety.
[0018] Specifically, the outer tube 421 can be made of a stainless steel tube, and the inner tube 422 can be made of a metal bellows, which can be bent into the interior of the outer tube 421, and the outer wall of the inner tube 422 is further provided with a tube clamp 424, such as Figure 2 As shown, the tube clamp 424 has multiple legs extending toward the outer tube 421, which are used to hold the inner tube 422 in the center of the outer tube 421. Multiple tube clamps 424 can be arranged in sequence along the length of the inner tube 422, and then the inner tube 422 is inserted into the outer tube 421. The phase-change thermal storage material 423 can be paraffin wax, which is relatively low in cost.
[0019] The outer walls of the water tank 41, the return pipe 44, the water storage tank 10, and the water supply pipe 21 are all provided with a thermal insulation layer to reduce heat loss.
[0020] Preferably, an inner tube is also provided inside the return pipe 44 , both ends of the inner tube are closed and filled with phase change heat storage material. The specific structure can refer to the heat exchange tube to increase the heat storage capacity.
[0021] The above is a description of one or more embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
