[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] See also Figure 1-4In the utility model, a self-regulating water-saving secondary water supply device comprises a mounting base 1, a water storage tank 2 is fixedly mounted on the mounting base 1, a voltage stabilizing compensator 3 is mounted on the top of the water storage tank 2, a water inlet pipe 11 is fixedly connected to the top of the water storage tank 2, a water outlet pipe 4 is fixedly mounted on the mounting base 1 and one side of the water outlet pipe 4 is connected and fixed with the water storage tank 2 through a vertical branch, a fixing frame 5 is mounted on the mounting base 1, three groups of booster pumps 6 arranged at equal distances are mounted on the fixing frame 5, the bottom input end of the booster pump 6 is vertically connected with the water outlet pipe 4 through a pipeline, a water supply pipe 7 is fixedly connected to the right side of the fixing frame 5, and the left side of the water supply pipe 7 is respectively connected and fixed with the output ends of the three booster pumps 6 through branches, an outlet energy storage regulating device 8 is mounted on the fixing frame 5, the bottom port of the outlet energy storage regulating device 8 is vertically connected and fixed with the water supply pipe 7, a pressure detection sensor 9 is mounted on the water supply pipe 7, and a frequency conversion control cabinet 10 is fixedly mounted on the mounting base 1.
[0022] In the utility model, the base 1 is installed as the support for the installation of the device. When in use, the municipal pipeline is connected to the inside of the water inlet pipe 11 to fill the water storage tank 2. The pressure stabilizing compensator 3 is used to adjust the pressure to stabilize when the water level inside the water storage tank 2 changes. During normal use, the three booster pumps 6 operate at the same time, the water inlet pipe 11 supplies water normally, and the booster pump 6 boosts the water supply of the water inlet pipe 11 to supply it to the user, ensuring the stability of the water pressure during peak hours. During peak hours, the outlet water pressure of the water supply pipe 7 is high. At this time, part of the high-pressure water flow enters the outlet energy storage regulating device 8 for storage. When the water consumption decreases, the pressure detection sensor 9 detects that the outlet water pressure of the water supply pipe 7 increases, and the frequency conversion control cabinet 10 starts to control the three booster pumps 6 to gradually sleep. Finally, when the water consumption is completely zero, all the booster pumps 6 are all dormant. At this time, during the low period of low water consumption, if a small amount of water is generated , then the high-pressure water flow inside the outlet energy storage regulating device 8 automatically flows out to supplement the pressure of the water supply pipe 7, avoiding repeated starting of the booster pump 6 until the water volume of the outlet energy storage regulating device 8 is exhausted. At this time, the pressure detection sensor 9 detects that the outlet water pressure of the water supply pipe 7 drops and reaches the set value. At this time, the frequency conversion control cabinet 10 gradually ends the dormancy of the booster pump 6, and flexibly adjusts the speed and start-up number of the booster pump 6 according to the pressure change, thereby realizing the device with a more energy-saving adjustment mode, extending the life of the motor, and the advantages of more flexible adjustment of water saving, solving the problem in the prior art that when a small amount of water is used, generally only one group of units will be operated to maintain the pressure, and the other units will be dormant to save electricity. However, this method still requires frequent starting and stopping during the period of small water use, which not only consumes the life of the motor, but also greatly reduces the effect of energy saving and water volume regulation, and the effect is not good.
[0023] See also Figure 2, wherein: the outlet energy storage regulating device 8 includes a connecting valve 81, a high-pressure resistant outer tank 82 and an elastic inner tank 83, the bottom port of the high-pressure resistant outer tank 82 is connected and fixed to the water supply pipe 7 through the connecting valve 81, the outer side of the high-pressure resistant outer tank 82 is fixedly connected to the fixing frame 5, the top and bottom of the elastic inner tank 83 are fixedly connected to the inner wall of the high-pressure resistant outer tank 82, and the bottom end of the elastic inner tank 83 is connected to the bottom port of the high-pressure resistant outer tank 82.
[0024] In the utility model, the water supply pipe 7 is connected to the high-pressure resistant outer tank 82 through the connecting valve 81, and the space between the high-pressure resistant outer tank 82 and the elastic inner tank 83 is filled with high-stability high-pressure nitrogen. The connecting valve 81 is used to conveniently disconnect the water supply to carry out inspection and maintenance of the high-pressure resistant outer tank 82. When the device is supplying water at full power and high pressure, part of the high-pressure water flows into the elastic inner tank 83 through the connecting valve 81, expands it, and compresses the nitrogen that already has pressure to store water and energy, so as to meet the small amount of water demand during low peak hours, and the energy-saving effect is better.
[0025] See also Figure 2 , wherein: an operating handle 811 is installed on the outer side of the connecting valve 81, and the operating handle 811 extends horizontally outward.
[0026] In the utility model, the switch of the connecting valve 81 can be conveniently controlled by operating the handle 811, which is convenient for inspection and maintenance operations.
[0027] See also Figure 1 , wherein: a liquid level sensor 21 is installed inside the water storage tank 2 , and the output end of the liquid level sensor 21 is electrically connected to the input end of the pressure detection sensor 9 .
[0028] In the utility model, the internal water level status of the water tank 2 is detected in real time by the liquid level sensor 21. When the municipal water supply is cut off, the water stored in the water tank 2 is used to maintain the water supply of the equipment. When the liquid level of the water tank 2 drops to a dangerous water level, the frequency conversion control cabinet 10 controls the booster pump 6 to stop working to avoid damage to the equipment.
[0029] See also Figure 1 , wherein: a maintenance check valve 41 is installed on the connecting branch between the water outlet pipe 4 and the water storage tank 2.
[0030] In the utility model, the check valve 41 is used to facilitate the inspection and maintenance of the water outlet pipe 4, and can prevent the backflow of water to generate negative pressure.
[0031] See also Figure 1 , wherein: a control check valve 71 is installed on the connecting branch between the water supply pipe 7 and the booster pump 6.
[0032] In the utility model, the check valve 71 is controlled to prevent the water flow inside the water supply pipe 7 from flowing back and generating negative pressure, and the inspection and maintenance operation is convenient.
[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
