Description

Technical Field

[0001] The utility model belongs to the field of water supply, and in particular relates to a pipeline node monitoring unit applied in a water supply pipeline and a secondary water supply system comprising the pipeline node monitoring unit. Background Art

[0002] The water supply system is a complex network designed to deliver clean and safe water from the water source to households, industries and commercial users. It is mainly composed of water sources, water treatment, water pumps or pumping stations, water pipelines, control systems and other parts. Large-scale water supply systems include municipal water supply systems, and small-scale water supply systems include community secondary water supply systems. Both large and small water supply systems need to be regularly inspected and maintained.

[0003] At present, the main force for inspection and maintenance of water supply systems is still patrol personnel. In order to cooperate with the work of patrol personnel, sensors are installed at key locations such as water pumps or pumping stations to monitor the operating conditions of water pumps or pumping station equipment in real time, and to centrally supervise key locations such as water pumps or pumping stations in the water supply system. As a result, the supervision of the water supply system pipelines is neglected. Due to the complexity of the pipeline distribution, when problems occur in the pipelines, they cannot be discovered and handled in time, affecting the normal water supply of the water supply system.

[0004] In response to the above problems, patent document CN113944883B discloses a monitoring and dispatching integrated system for urban water supply networks, which discloses that multiple network monitoring units are set on the pipelines. The network monitoring units are used to monitor the water pressure, water flow, and water quality information of the water supply network measurement points, and the water pressure of the water supply pipes at each monitoring point is tracked in real time through the network monitoring units. Although this solution pays attention to the working conditions of each measurement point in the network, when an abnormal situation occurs in the measurement point pipeline, the water pressure can only be adjusted through the water supply pressure equipment associated with the pipeline, and there is a lack of means for more detailed regulation. Utility Model Content

[0005] The utility model aims to overcome the problem of lack of monitoring of existing water supply system pipelines, and to provide a pipeline node monitoring unit capable of performing discrete section monitoring on the water supply system pipelines and a secondary water supply system including the pipeline node monitoring unit.

[0006] The utility model solves the technical problem by adopting a timely solution: a pipeline node monitoring unit comprises a receiving pipe, a solenoid valve, a pressure sensor and a flow sensor, wherein the solenoid valve, the pressure sensor and the flow sensor are connected in series on the receiving pipe, and connectors are provided at both ends of the receiving pipe.

[0007] Optionally, a power distribution module and a wireless communication module protected by a shell are fixed on the receiving tube, the power distribution module is electrically connected to the wireless communication module, and the solenoid valve, pressure sensor and flow sensor are electrically connected to the power distribution module and the wireless communication module respectively.

[0008] Optionally, a temperature sensor, a visual sensor and a water quality sensor are also provided on the receiving pipe, and the temperature sensor, the visual sensor and the water quality sensor are electrically connected to the power distribution module and the wireless communication module respectively.

[0009] Optionally, the connecting piece is a pipe joint or a flange.

[0010] The secondary water supply system includes a control center, secondary water supply equipment and pipelines. A plurality of pipeline node monitoring units are distributed in the pipelines, and the pipeline node monitoring units communicate with the control center in real time.

[0011] Usage and principle of the utility model: when in use, multiple pipeline node monitoring units are distributed in the pipeline of the water supply system and connected in series therewith. The pipeline node monitoring units are powered on and communicate with the control center of the water supply system in real time through wired or wireless forms. The pipeline node monitoring units can have their own position information, and the control center can also mark the position of the pipeline node monitoring units. The pipeline node monitoring units collect the working condition information of the pipeline section through their own sensors and transmit it to the control center in real time. The control center adjusts the opening and closing and the opening degree of the solenoid valve of the pipeline node monitoring unit according to the working condition information of the section, so as to achieve the regulation of pipeline pressure and pre-processing and alarm when a fault occurs, thereby realizing a more stable water supply pressure and ensuring normal water supply to the maximum number of users.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model can monitor and control the pipeline sections of the water supply system, so that the water supply system can realize discrete automatic monitoring of the entire pipeline, thereby effectively reducing the hazards of system failures, achieving a more stable water supply pressure in the system and ensuring normal water supply to the maximum number of users in the system.
