[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 2 The utility model provides an embodiment: energy-saving variable frequency water supply equipment, including an electric control cabinet 1, a water tank 3, a low water level sensor 4 is fixedly connected to the water tank 3, the low water level sensor 4 is electrically connected to the electric control cabinet 1, a water outlet pipe 12 is fixedly connected to the water tank 3, a shunt pipe 13 is fixedly connected to the water outlet pipe 12, three groups are arranged on the shunt pipe 13, a butterfly valve 6 is fixedly connected to the shunt pipe 13, a check valve 7 is fixedly connected to the shunt pipe 13, and a water supply pipe 14 is fixedly connected to the end of the shunt pipe 13 away from the water outlet pipe 12. Through the integrated variable frequency control technology, the water pump 5 can automatically adjust the speed and flow rate according to actual needs, avoiding the high energy consumption of traditional constant speed pumps at partial load. When the water demand is small, the water pump 5 slows down and runs, significantly reducing energy consumption and achieving high efficiency and energy saving. At the same time, the low water level sensor 4 monitors the water level of the water tank 3 in real time. Once the water level is lower than the preset threshold, the water replenishment mechanism is automatically triggered to prevent the water pump 5 from idling, protect the equipment and ensure the continuity of water supply.

[0027] A rubber flexible connector 8 is fixedly connected to the shunt pipe 13, and a water pump 5 is fixedly connected to the end of the rubber flexible connector 8 away from the shunt pipe 13. A pressure sensor 9 is fixedly connected to the water supply pipe 14, and a pressure gauge 10 is fixedly connected to the water supply pipe 14. A pressure stabilizing tank 11 is arranged on the water supply pipe 14. A low water level sensor 4, a water pump 5, a butterfly valve 6, a check valve 7, a pressure sensor 9, a pressure gauge 10, and a pressure stabilizing tank 11 are electrically connected to the electric control cabinet 1. A tap water pipe 15 is fixedly connected to the water tank 3, and a liquid level control valve 2 is fixedly connected to the tap water pipe 15. The liquid level control valve 2 is located directly above the water tank 3. The length and width of the water tank 3 are as follows: The dimensions of the water supply pipe 14 are 4000CM and 3000CM, and the length and width of the electric control cabinet 1 are 2300CM and 1500CM. The pressure sensor 9 arranged on the water supply pipe 14 cooperates with the pressure regulating tank 11 to ensure that the water supply pressure is stable within the set range, avoiding water inconvenience or equipment damage caused by pressure fluctuations. This not only improves the user experience, but also extends the service life of pipelines and water-using equipment. At the same time, the check valve 7 equipped in the system effectively prevents water backflow and protects the safety of the water supply system. At the same time, the application of rubber soft connectors 8 reduces vibration and noise transmission, and improves the operating stability and service life of the equipment.

[0028] Working principle: First, a low water level sensor 4 is fixedly installed on the water tank 3. The sensor monitors the water level in the water tank 3 in real time. When the water level drops to the preset low water level threshold, the low water level sensor 4 will send a signal to the electric control cabinet 1. After receiving the low water level signal, the electric control cabinet 1 will immediately trigger the alarm mechanism to remind the operator to pay attention to the water level of the water tank 3 and may start the water replenishment program. When the water level of the water tank 3 is lower than the set value, the electric control cabinet 1 will control the liquid level control valve 2 on the tap water pipe 15 to open, allowing tap water to enter the water tank 3 until the water level reaches a safe level. After confirming that the water level in the water tank 3 is sufficient, the electric control cabinet 1 will start the water pump 5 according to the water supply demand. The water pump 5 is connected to the diverter pipe 13 through a rubber soft connector 8 to reduce vibration and noise transmission. Then the water pump 5 adopts frequency conversion technology to automatically adjust the speed according to the actual demand of the water supply pipe 14. When the water supply demand increases, the speed of the water pump 5 increases to increase the water supply. Conversely, when the demand decreases, The rotation speed is reduced, and energy consumption is reduced. The butterfly valve 6 arranged on the shunt pipe 13 is used to adjust the water supply of each branch, and the check valve 7 prevents the water from flowing back, so as to ensure the stability and safety of the water supply system. In this way, the water flow can be prevented from flowing back on the water supply pipe 14. A pressure-stabilizing tank 11 is arranged on the water supply pipe 14 to provide a stable water supply pressure during peak water use or when the water pump 5 is temporarily shut down, so as to reduce the impact of pressure fluctuations on the system. Secondly, a pressure sensor 9 and a pressure gauge 10 are installed on the water supply pipe 14 to monitor the water supply pressure in real time. When the pressure exceeds the preset range, the electric control cabinet 1 will adjust the rotation speed of the water pump 5 or start the standby pump to maintain the stability of the water supply pressure. Therefore, the electric control cabinet 1 integrates a variety of sensors and controllers, so as to realize the intelligent management of the entire water supply system, including automatic water replenishment, frequency conversion control of the water pump 5, pressure monitoring and regulation and other functions, thereby reducing manual intervention and improving the automation degree and operation efficiency of the system.
