Description

Technical Field

[0001] This utility model relates to the field of low-pressure water supply technology, specifically to an Internet of Things (IoT) low-pressure water supply structure. Background Technology

[0002] Networked low-pressure water supply refers to using Internet of Things (IoT) technology to monitor and control the pressure and flow of a water supply system, enabling more intelligent water resource management. In traditional water supply systems, pressure and flow control typically relies on manual operation and periodic inspections, which can lead to water waste and system instability. IoT technology, however, allows for real-time monitoring of water supply network pressure and flow data, and enables automatic adjustments via remote control systems, thereby improving water supply efficiency and reliability.

[0003] In IoT-based low-pressure water supply systems, various sensors and actuators are typically installed to collect and control data. For example, pressure sensors monitor water pressure in pipes, flow sensors measure the rate of water flow, and temperature and water quality sensors monitor water quality. These sensors transmit data to a central control system, which analyzes the data and makes corresponding decisions, such as adjusting the operating status of pump stations or opening or closing valves, to maintain appropriate water pressure and flow.

[0004] In existing IoT pipeline sub-units or IoT metering water supply systems, for low-pressure water supply, there are often problems such as limited functionality of pipeline sub-units, inaccurate water flow measurement, and inconvenience in managing multiple water supply units. Therefore, these systems do not meet the current needs. To address this, we propose an IoT low-pressure water supply structure. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Example 1: This example aims to address the shortcomings of existing IoT-enabled water supply systems with pipeline units or IoT metering devices. In low-pressure water supply scenarios, these systems often suffer from issues such as limited functionality of the pipeline units, inaccurate flow measurement by the water purification flow meter (120), and inconvenient management of multiple water supply lines (112). Please refer to [link / reference needed]. Figures 1-4 A low-pressure water supply structure for the Internet of Things (IoT) includes a pressure tank 110, a cold water tank 111, a water pipe 112, a self-priming booster pump 113, a flow switch 114, a main unit 115, and a secondary unit 116. The secondary unit 116 is located to the side of the main unit 115 and to one side of the pressure tank 110. The cold water tank 111 is located to the other side of the pressure tank 110. The water pipe 112 connects the pressure tank 110 and the cold water tank 111. The self-priming booster pump 113 is mounted on the water pipe 112. A water hammer eliminator 117 is mounted on the side of the self-priming booster pump 113. An inlet solenoid valve 118 is mounted on the side of the water hammer eliminator 117. A flow switch 114 is mounted on the side of the inlet solenoid valve 118. A TDS probe 119 is mounted on the side of the flow switch 114. A flow meter 120 is mounted on the side of the TDS probe 119. An inlet 121 is provided at the end of the water pipe 112.

[0024] There are three secondary sub-units 116. The three secondary sub-units 116 are connected to the main sub-unit 115 by a first connecting pipe 122. The main sub-unit 115 is connected to the flow meter 120 by a second connecting pipe 123.

[0025] The water pipe 112 includes a first branch pipe 124 and a second branch pipe 125. The first branch pipe 124 is located at the bottom of the second branch pipe 125. One end of the first branch pipe 124 is connected to the flow meter 120 and the cold water tank 111. One end of the second branch pipe 125 is connected to the flow meter 120, and the other end of the second branch pipe 125 is connected to the pressure tank 110. A connecting end 126 is installed on the end of the second connecting pipe 123. The main unit 115 has a connecting port 127 corresponding to the connecting end 126, and the connecting end 126 is inserted into the connecting port 127.

[0026] If the main control board of the device's IoT system has water, but the cold water tank 111, pressure tank 110, and the sub-unit connected to the sub-unit connection port 127 are in a water shortage state, the high-pressure switch will close and conduct. Simultaneously, the inlet solenoid valve 118 will be energized and open the water circuit switch. Cold purified water flows through the inlet 121, through the self-priming booster pump 113, water hammer eliminator 117, inlet solenoid valve 118, high-pressure check valve, high-pressure switch, TDS probe, and high-precision flow meter 120, respectively, into the cold water tank 111, pressure tank 110, and the sub-unit connected to the sub-unit connection port 127. If the inlet pressure is too low, the self-priming booster pump 113 will also draw water from the pipeline to the cold water tank 111, pressure tank 110, and the sub-unit connected to the sub-unit connection port 127. Once the main sub-unit 115, cold water tank 111, pressure tank 110, and the sub-unit connected to the sub-unit connection port 127 are all full, the high-pressure switch will trip. The device enters standby mode.

[0027] When the water consumption in the device's IoT main control board reaches 0, the IoT main control board will enter a locked state, and the water inlet solenoid valve 118 will lose power and enter a water circuit closed state.

[0028] In this embodiment, by setting up multiple secondary sub-units 116 and connecting them to the main sub-unit 115 via the first connecting pipe 122, the system can simultaneously supply water to multiple terminal devices, thereby solving the problem of the single function of pipeline sub-units in the existing system and enhancing the system's flexibility and scalability. The main sub-unit 115 is connected to the flow meter 120 via the second connecting pipe 123 to monitor the purified water flow in real time, ensuring the accuracy of the flow meter 120 in the water supply system and solving the problem of inaccurate flow meter readings in the existing system.

[0029] Example 2 aims to address the problem of water pipe 112 becoming loose or detached due to vibration or water pressure fluctuations. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-4 A retaining ring 130 for external installation is fitted onto the water pipe 112. A retaining plate 131 is mounted on the retaining ring 130. A threaded hole 132 is formed on the retaining plate 131, and a threaded rod 133 is threaded into the threaded hole 132. An internal threaded ring 134 is provided in the connection port 127, and an external threaded ring 135 is provided on the outside of the connection end 126. The external threaded ring 135 is threadedly connected to the internal threaded ring 134.

[0030] A sealing ring 140, made of rubber, is fitted over the water pipe 112 near the water inlet 121. The sealing ring 140 provides good elasticity and sealing performance, effectively preventing leakage between the water pipe 112 and the water inlet 121. Anti-slip pads 141, also made of rubber, are installed at the bottom of both the main unit 115 and the secondary unit 116. These anti-slip pads provide good anti-slip performance, effectively preventing the equipment from sliding due to vibration or external forces during operation, thus improving the stability and safety of the equipment.

[0031] In this embodiment: a fixing ring 130 is fitted onto the water pipe 112, and a fixing plate 131 is mounted on the fixing ring 130. The fixing plate 131 has a threaded hole 132, and a threaded rod 133 is threaded into the threaded hole 132. This design makes the installation of the water pipe 112 more stable and facilitates its fixation to the external structure. The threaded connection ensures that the water pipe 112 is firmly connected to other equipment, preventing the water pipe 112 from loosening or falling off due to vibration or water pressure fluctuations.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
