Description

Technical Field

[0001] This application relates to the field of water supply equipment technology, specifically a constant pressure water supply device with pressure adaptive regulation. Background Technology

[0002] The development of water supply equipment technology is driven by multiple factors. Population growth and urban expansion have highlighted the inefficiency of traditional equipment, while rising water demand has forced technological upgrades. Energy conservation and environmental protection requirements have spurred the development of energy-saving technologies such as variable frequency speed control to reduce energy consumption and water waste.

[0003] A search revealed a constant pressure water supply device with pressure adaptive regulation, patent publication number "CN219411068U". This device features a multi-stage pump, along with a threaded shaft and water pumps, allowing for multi-user operation and adjustable water flow rates. To ensure the device can meet the needs of multiple users, the multi-stage pumps are evenly installed on all four sides of the water pump, improving the device's efficiency. The water flow rate of the multi-stage pumps can be adjusted by regulating the threaded bolts, thus better protecting the multi-stage pumps from damage. Furthermore, a remote pressure gauge and frequency converter record the user's water flow rate and usage. The water pump control software automatically adjusts parameters based on changes in user flow, achieving an adaptive function.

[0004] The above technical features have the following shortcomings: the device adjusts the water flow rate by using a multi-stage pump in conjunction with a threaded shaft and a water pump, but its flow rate detection relies on remote pressure gauges and frequency converters to record data. This indirect detection method may have data lag or deviation. In addition, as a user water supply device, the device does not have a substantial water quality filtration and detection structure. During long-term operation, it is impossible to control the water quality, which may affect water safety.

[0005] Therefore, a constant pressure water supply device with adaptive pressure regulation is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-6 This utility model provides a technical solution for a constant pressure water supply device with adaptive pressure regulation: A constant pressure water supply device with adaptive pressure regulation includes a water tank 1 and a main water pipe 2 connected to the outer wall of the water tank 1. A passive valve mechanism is provided on the outer wall of the main water pipe 2 near the water tank 1. A filter box 5 is fixedly connected to the other side of the main water pipe 2 and the passive valve mechanism. Multiple filter plates 6 are slidably installed inside the filter box 5. A handle 7 is fixedly connected to the outer wall of the common side of the multiple filter plates 6. A pressure regulating chamber 10 is connected to the other side of the filter box 5. A water quality detection mechanism for detecting water quality is provided between the filter box 5 and the pressure regulating chamber 10. A water turbine blade 12 is rotatably installed inside the pressure regulating chamber 10. A main shaft 13 is fixedly connected to one side of the water turbine blade 12. One end of the main shaft 13 passes through the inner wall of the pressure regulating chamber 10 and is connected to a speed detection drive mechanism.

[0026] In this embodiment, a detection water pipe 23 is fixedly connected to the output end of the filter box 5, and a regulating chamber connecting pipe 11 is fixedly connected to the output end of the detection water pipe 23. The other side of the regulating chamber connecting pipe 11 is fixedly connected to the outer wall of the pressure regulating chamber 10. The water quality detection mechanism includes a detection pipe 8 fixedly installed on the outer wall of the output end of the filter box 5. A detection device 9 for detecting water quality is fixedly connected to the outer wall of the detection pipe 8. The detection device 9 is linked with the alarm system. When the water quality does not meet the standard, the alarm is automatically triggered. The other side of the detection pipe 8 is fixedly connected to the outer wall of the detection water pipe 23. Part of the water output from the filter box 5 enters the detection device 9 through the detection pipe 8. The detection device 9 analyzes the water quality and provides real-time feedback on the quality status of the filtered water.

[0027] In this embodiment, the passive valve mechanism includes a valve rod 4 rotatably mounted on the outer wall of the main water pipe 2. The other end of the valve rod 4 passes through the outer wall of the main water pipe 2 and a circular valve 3 is fixedly connected to its end. Rotating the valve rod 4 on the outer side of the main water pipe 2 causes the circular valve 3 at its end to rotate inside the main water pipe 2. When the circular valve 3 is perpendicular to the diameter of the main water pipe 2, the water flow is closed; when it is parallel, it is fully open, thereby realizing the control of water flow interruption in the main water pipe 2.

[0028] In this embodiment, the speed detection drive mechanism includes a rotating wheel 14 fixedly connected to one end of the main shaft 13. A fixing ring 15 is rotatably mounted on the outer wall of the rotating wheel 14. A plurality of fixing rods 17 are fixedly connected to the outer wall of the fixing ring 15. The other ends of the plurality of fixing rods 17 are fixedly mounted on the outer wall of the pressure regulating chamber 10. The rotation of the main shaft 13 drives the rotating wheel 14 to rotate synchronously. The fixing ring 15 is fixed to the outer wall of the pressure regulating chamber 10 through the fixing rods 17, providing stable support for the rotating wheel 14 and ensuring good concentricity when it rotates.

[0029] In this embodiment, two fixed side plates 19 are fixedly connected to the outer wall of the other side of the fixed ring 15. Infrared detectors 16 are fixedly connected to the opposite side of the two fixed side plates 19. Servo reducer motors 20 are fixedly connected to the opposite side of the two infrared detectors 16. The output end of the servo reducer motor 20 is fixedly connected to the outer wall of the wheel 14. Holes are opened on the outer wall of the wheel 14 corresponding to the positions of the two infrared detectors 16. Infrared emitters 18 are fixedly connected to the outer wall of the pressure regulating chamber 10 corresponding to the positions of the two infrared detectors 16. When the wheel 14 rotates, the infrared emitter 18 on the outside of the pressure regulating chamber 10 emits infrared light. When the wheel 14 rotates, the holes on its outside rotate with it. When the infrared light passes through the holes, it is received by the infrared detectors 16. The rotation speed of the wheel 14 is calculated by the signal on / off frequency. The infrared detectors 16 detect its rotation speed. The servo reducer motor 20 outputs driving force to the wheel 14 according to the detection result. By controlling the rotation speed of the wheel 14 to counteract the rotation speed driven by the water flow, the water flow rate and pressure are adjusted.

[0030] In this embodiment, auxiliary water pipes 21 are fixedly installed on both sides of the pressure regulating chamber 10. Multiple branch water pipes 22 are connected to the outer walls of the two auxiliary water pipes 21. The constant pressure water flow after being regulated by the pressure regulating chamber 10 is diverted to the auxiliary water pipes 21 on both sides, and then transported to different water terminals through the multiple branch water pipes 22 on the auxiliary water pipes 21.

[0031] The working principle is as follows: During use, first rotate the valve stem 4 on the outside of the main water pipe 2, causing the circular valve 3 at the end to rotate inside the main water pipe 2. Water from the water tank 1 flows into the filter box 5 through the main water pipe 2. Inside the filter box 5, the water undergoes multi-layer filtration through multiple slidingly installed filter plates 6. These filter plates can be periodically removed for cleaning or replacement using the handle 7. The filtered water is then transported to the pressure regulating chamber 10 via the detection pipe 23. During this process, some water flows through the detection pipe 8 into the detection device 9, which detects impurities, pH value, and other indicators in the water, providing real-time feedback on the filtered water quality. Meanwhile, during the water pressure regulation stage… In the first stage, the water flow drives the water turbine blades 12 in the pressure regulating chamber 10 to rotate, and the main shaft 13 rotates synchronously with it. The infrared light emitted by the infrared transmitter 18 is received by the infrared detector 16 through the hole on the rotor 14. The rotation speed is calculated by the signal frequency to obtain the water flow speed information. According to the rotation speed data, the servo reduction motor 20 outputs a corresponding reverse torque to act on the rotor 14 to adjust its rotation resistance, thereby controlling the rotation speed of the water turbine blades 12 to stabilize the water pressure and form a counterforce with the water flow to regulate the water pressure. Finally, the constant pressure water flow is diverted through the auxiliary water pipes 21 on both sides of the pressure regulating chamber 10 to multiple branch water pipes 22 and delivered to each water point.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
