Description

Technical Field

[0001] This utility model belongs to the technical field of secondary water supply equipment, and more specifically, it relates to a water supply network pressure regulating and energy-saving device. Background Technology

[0002] In the field of secondary water supply technology, water supply equipment is often needed to ensure users' water needs. For example, in the water supply of high-rise buildings, a water supply network pressure regulating and energy-saving device is particularly important to ensure that each floor receives stable water pressure. Traditional water supply network pressure regulating equipment often faces problems such as unstable water pressure and energy waste.

[0003] However, traditional water supply network pressure regulating and energy-saving devices do not have good pressure stabilization and filtration detection functions. As a result, during long-term water supply, the water pressure in the pipeline fluctuates greatly and there are more impurities in the water flow. The water pump will start and stop frequently, which will accelerate the wear and tear of the water pump components. Under the impact of the water flow, the pipe connection is prone to loosening and leakage, which will easily lead to water waste. This will not only affect the stability of the water supply and cause insufficient water pressure on some floors, but also increase energy consumption due to the ineffective operation of the water pump, thereby increasing the water supply cost. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a water supply network pressure regulating and energy-saving device, which solves the technical problem that traditional water supply network pressure regulating and energy-saving devices do not have good pressure stability and filtration detection functions.

[0005] The purpose and effect of this utility model's water supply network pressure regulating and energy-saving device are achieved by the following specific technical means:

[0006] A water supply network pressure regulating and energy-saving device includes an installation plate, and a pressure stabilizing component is installed on the top of the installation plate.

The first pressure stabilizing gas tank and the second pressure stabilizing gas tank are symmetrically arranged above the installation plate.

[0007] Multiple sets of variable frequency pumps are installed between the first pressure-stabilizing gas tank and the second pressure-stabilizing gas tank. The input end pipe of the variable frequency pump is connected to a filter element for easy disassembly and observation of water quality, and the output end pipe of the variable frequency pump is connected to a turbine generator for power generation and energy saving.

[0008] The top of the mounting plate is equipped with multiple sets of acceleration sensors for detecting whether the device parts are loose, the bottom of the mounting plate is equipped with a rubber pad, and a controller is installed at one end of the mounting plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting up a first pressure-stabilizing gas tank and a second pressure-stabilizing gas tank, this utility model enables the device to stabilize the pressure at the inlet and outlet of the water supply network, thereby improving the device's pressure regulation capability.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0029] Example:

[0030] like Figures 1 to 5As shown, this utility model provides a water supply network pressure regulating and energy-saving device, including a mounting plate 11. The mounting plate 11 provides a stable installation foundation for the entire device, allowing it to be placed in a predetermined position and improving its stability.

[0031] A pressure stabilizing assembly is installed on the top of the mounting plate 11. The pressure stabilizing assembly includes a first pressure stabilizing tank 12 for stabilizing the pressure at the inlet of the device and a second pressure stabilizing tank 13 for stabilizing the pressure at the outlet of the device. By setting the first pressure stabilizing tank 12 and the second pressure stabilizing tank 13, the pressure at the inlet and outlet can be stabilized respectively, so that the device can adapt to different water pressure conditions and improve the device's ability to regulate pressure.

[0032] Both the first pressure-stabilizing gas tank 12 and the second pressure-stabilizing gas tank 13 are equipped with vacuum suppressors to ensure that the device does not generate negative pressure. The first pressure-stabilizing gas tank 12 and the second pressure-stabilizing gas tank 13 are symmetrically arranged above the mounting plate 11. This symmetrical layout helps to balance the overall stress on the device, making the device operate more smoothly.

[0033] Multiple sets of variable frequency pumps 14 are installed between the first pressure stabilizing gas tank 12 and the second pressure stabilizing gas tank 13. The device can adjust the water pressure and flow rate according to the actual water demand through the operation of the variable frequency pumps 14, so that the device can cope with different water use scenarios and improve the device's adaptability in water supply.

[0034] like Figures 2 to 4 As shown, the input pipe of the variable frequency pump 14 is connected to a filter element, which includes an installation pipe 22 and a transparent semi-circular tube 23. The transparent semi-circular tube 23 can be easily installed in the installation groove on the installation pipe 22, making the device more compact and reasonable in structure. Both the installation pipe 22 and the transparent semi-circular tube 23 have slots, in which filter elements 24 are held. The device can filter water by using this method of holding the filter elements 24, removing impurities and improving its water purification capacity. At the same time, the transparent semi-circular tube 23 allows operators to directly observe the water quality, enhancing the convenience of water quality monitoring. The transparent semi-circular tube 23 can be made of HDPE material.

[0035] Multiple sets of leak-proof gaskets 25 are installed at the connection between the transparent semi-circular tube 23 and the installation pipe 22. Leak-proof baffles 26 are installed at both ends of the installation groove. The installation of leak-proof gaskets 25 and leak-proof baffles 26 can prevent water leakage at the connection, so that the device can maintain good sealing during long-term operation and improve the reliability of the device.

[0036] The output pipe of the variable frequency pump 14 is connected to a turbine generator 15 for power generation and energy saving. The device can drive the turbine generator 15 to operate through water flow, providing additional electrical energy to the controller 18, thereby achieving the purpose of power generation and energy saving. This allows the device to recover some energy during the water supply process, improving the energy utilization efficiency of the device and enhancing its energy-saving capabilities. The controller 18 can be an FS300 type controller.

[0037] like Figure 1 , Figure 2 As shown, multiple sets of acceleration sensors 16 are installed on the top of the mounting plate 11 to detect whether the device parts are loose. By setting up the acceleration sensors 16, the vibration of each part of the device can be monitored. Once a part becomes loose, the acceleration sensors 16 can detect it in time and provide feedback, enabling the device to provide early warning of potential safety hazards and improving the safety of the device's operation. The acceleration sensors 16 can be BMI160 type inertial measurement units.

[0038] The bottom of the mounting plate 11 is equipped with a rubber pad 17. The rubber pad 17 can play a role in shock absorption and buffering, reducing the transmission of vibration generated during the operation of the device to the ground, making the device operate more smoothly, and also reducing noise, thus improving the device's operational stability and noise reduction capabilities.

[0039] The mounting plate 11 has a controller 18 installed at one end. The device can centrally control and adjust the operating parameters of the entire device by remotely or directly operating the controller 18, so that the device can operate according to the actual situation.

[0040] The bottom of the first pressure-stabilizing gas tank and the second pressure-stabilizing gas tank are respectively welded with a first bracket 19 and a second bracket 21. The bottom of the first bracket 19 and the second bracket 21 are threaded to the mounting plate 11. The first bracket 19 and the second bracket 21 can further fix the pressure-stabilizing gas tank, making the overall structure of the device more reliable and improving the structural stability of the device.

[0041] like Figures 1 to 3 As shown, the multiple variable frequency pumps 14 are divided into two groups. Each group of pumps 14 has a temperature sensor 27 installed on its motor to detect motor overload. By monitoring the motor temperature using the temperature sensor 27, an overload can be detected, causing the temperature to rise. The temperature sensor 27 will promptly send a signal, allowing the device to take timely measures to prevent motor damage and improving the safety of motor operation. The temperature sensor 27 can be a PT100 resistance temperature sensor.

[0042] The output ends of the two sets of variable frequency pumps 14 are connected through the first water supply pipe 28, which is connected to the input end of the turbine generator 15. The output end of the turbine generator 15 is connected to the input end of the second pressure stabilizing gas tank 13 through the second water supply pipe 29. This pipeline connection method not only enables the reuse of energy, but also allows the water to flow along a predetermined path, ensuring smooth water transmission between components and improving the overall operating efficiency of the device.

[0043] A pressure sensor 32 is installed on the second water supply pipe 29, and a flow sensor 33 is installed at the output end of the second pressure stabilizing tank 13. By setting up the pressure sensor 32 and the flow sensor 33, the pressure and flow information of the water can be monitored, enabling the device to adjust its operating parameters in a timely manner based on this data, thus improving the device's ability to monitor and control water flow parameters. The pressure sensor 32 can be a PX409 series pressure sensor, and the flow sensor 33 can be a CN351 type flow sensor.

[0044] The input ends of the two sets of variable frequency pumps 14 are connected by a three-way pipe 34. The three-way pipe 34 is connected to the output flange of the installation pipe 22. The input end of the installation pipe 22 is connected to the output flange of the first pressure stabilizing gas tank 12 through the third water supply pipe 31. Through this pipe connection structure, the water flow can be reasonably distributed, making the device more scientific and reasonable in terms of water flow distribution and improving the water flow distribution efficiency of the device.

[0045] The specific usage and function of this embodiment are as follows:

[0046] The device is supported by the mounting plate 11, and the rubber pad 17 plays a role in shock absorption and noise reduction, providing a foundation for the stable operation of the entire device. The acceleration sensor 16 monitors the vibration of the device parts. Once there are signs of loosening of the parts, it can promptly feed back to the controller 18. The controller 18 then remotely connects to a mobile phone or computer to remind the staff to perform maintenance and ensure the safe operation of the device.

[0047] The first pressure stabilizing gas tank 12 stabilizes the pressure at the inlet of the device. When the inlet pressure of the water supply network fluctuates, the first pressure stabilizing gas tank 12 acts as a buffer, absorbing or releasing pressure to keep the water pressure entering the subsequent components relatively stable. For example, when the inlet pressure decreases during peak water usage, the gas tank releases gas to replenish the pressure and ensure that the subsequent components work normally.

[0048] The second pressure stabilizing tank 13 is responsible for stabilizing the water pressure at the outlet of the device. After being pressurized by the variable frequency pump 14 and generated by the turbine generator 15, the water flows into the second pressure stabilizing tank 13, where it is pressure stabilized to ensure that the water pressure output to the user is stable and to avoid damage to the user's water equipment due to water pressure fluctuations.

[0049] The two sets of variable frequency pumps 14 and the filter stage adjust the water pressure and flow rate by changing the motor speed under the control of the controller 18 according to the actual water demand. The temperature sensor 27 monitors the motor temperature of the variable frequency pump 14. If the motor overloads and the temperature rises, it will promptly feed back to the controller 18 to avoid motor damage. The controller 18 will stop or run the variable frequency pump 14 according to the temperature.

[0050] The filter element connected to the input end of the variable frequency pump 14 has an installation pipe 22 that matches the transparent semi-circular tube 23. The filter element 24 is stuck in the slot to filter the water entering the variable frequency pump 14. The transparent semi-circular tube 23 allows the operator to visually observe the water quality. If the water quality deteriorates, the leak-proof baffle 26 can be opened, and the filter element 24 can be removed and replaced through the slot. The leak-proof pad 25 ensures that there is no water leakage at the connection between the transparent semi-circular tube 23 and the installation pipe 22.

[0051] In the power generation and energy saving process, the water flow output by the variable frequency pump 14 drives the turbine generator 15 to operate, converting part of the kinetic energy of the water flow into electrical energy, thereby achieving power generation and energy saving. This part of the electrical energy can be fed back to the device or integrated into other power systems, thus improving energy utilization efficiency.

[0052] In the monitoring and control process, the pressure sensor 32 on the second water supply pipe 29 monitors the pressure of the water flow after passing through the turbine generator 15, and the flow sensor 33 at the output end of the second pressure stabilizing tank 13 monitors the outflow rate. These data are transmitted to the controller 18, which adjusts the working state of the variable frequency pump 14 based on the pressure and flow data to ensure that the device is always in a stable operating state.

[0053] In the water distribution stage, the input ends of the two sets of variable frequency pumps 14 are connected by a three-way pipe 34. The three-way pipe 34 is connected to the output end of the installation pipe 22. The installation pipe 22 is then connected to the output end of the first pressure stabilizing tank 12 through the third water supply pipe 31, ensuring that each component can obtain water of appropriate flow rate and making the whole device operate smoothly.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
