Description
Technical Field
[0001] This utility model belongs to the field of water supply system technology, specifically relating to a water supply main pipeline pumping control system. Background Technology
[0002] Currently, many villages suffer from unstable water levels in their main water supply pipelines. Sometimes the pipelines contain water, sometimes not, causing the pipeline pumps to run dry and waste energy, frequently burning out motors. While attempts have been made to avoid peak water usage times and control pump operation with float switches, these fully automated measures have proven unreliable, with pumps still frequently running dry due to empty pipelines. To solve the problem of pipeline pumps failing to pump properly due to unstable water levels in the main pipelines, relying solely on intelligent systems is insufficient, and manual labor is also problematic. During pumping, managers must constantly monitor the pressure gauges, and if no water is available, the power must be immediately shut off, consuming a significant amount of time and effort.
[0003] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a water supply main pipeline pumping control system. Utility Model Content
[0004] The purpose of this invention is to provide a water supply main pipeline pumping control system, which can solve the problem that the pipeline pump cannot pump water normally due to unstable water level in the main water supply pipeline.
[0005] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0006] A water supply main pipeline pumping control system includes a 4G three-phase remote switch, a pipeline pump, a first time-delay relay, a second time-delay relay, a three-phase relay, a self-resetting electric ball valve, an exhaust pipe, a pipeline level sensor, an intermediate relay, a 220V to 24V transformer, a pipeline pressure gauge, and a monitoring camera.
[0007] The 4G three-phase remote switch is connected to the pipeline level sensor, intermediate relay, first time delay relay and second time delay relay respectively through a 220V to 24V transformer. The normally open contact of the intermediate relay is connected to the coil circuit of the first time delay relay and the three-phase relay respectively. The self-resetting electric ball valve is installed on the exhaust pipe and controlled by the second time delay relay. The monitoring camera is aimed at the pipeline pressure gauge and the exhaust pipe outlet.
[0008] In one or more embodiments of this utility model, the self-resetting electric ball valve is configured to have its opening action prioritized over the start of the pipeline pump via a second time delay relay, and the pipeline pump is configured to start after the self-resetting electric ball valve is fully closed via a first time delay relay.
[0009] In one or more embodiments of this utility model, the pipeline liquid level sensor is provided with a four-wire output interface, wherein the four wires include a yellow wire, a blue wire, a black wire, and a brown wire;
[0010] The yellow wire is connected to the negative terminal of the intermediate relay, the blue and black wires are connected together to the negative terminal of the 220V to 24V transformer, and the brown wire is connected to the positive terminal of the 220V to 24V transformer.
[0011] In one or more embodiments of this utility model, the negative terminal of the 220V to 24V transformer is also simultaneously connected to the d contact of the second time delay relay and the i contact of the first time delay relay.
[0012] In one or more embodiments of this utility model, the positive terminal of the 220V to 24V transformer is also connected to the positive terminal of the intermediate relay and the c and e contacts of the second time delay relay, and the f contact of the second time delay relay is connected to the negative terminal of the self-resetting electric ball valve.
[0013] In one or more embodiments of this utility model, the normally open contact a of the intermediate relay is connected to the normally open contact h of the first time delay relay, the normally open contact b of the intermediate relay is connected to the neutral line N and the coil neutral line of the three-phase relay, and the contact g of the first time delay relay is connected to the coil live line of the three-phase relay.
[0014] In one or more embodiments of this utility model, the first and second time-delay relays are adjustable time relays. The second delay range is set to close after 10 seconds, which is the time it takes for the self-resetting electric ball valve to fully open. After power failure, the self-resetting electric ball valve will self-reset within 10 seconds. The first delay is set to open after 20 seconds, which means that the pipeline pump will automatically start when the self-resetting electric ball valve is fully closed. The first and second time-delay relays are adjustable time relays.
[0015] In one or more embodiments of this utility model, the monitoring camera is a network camera with night vision function, which shares a communication module with a 4G three-phase remote switch to realize remote video monitoring.
[0016] In one or more embodiments of this utility model, the 4G three-phase remote switch integrates an Internet of Things (IoT) communication module, which supports remote power control, status monitoring, and alarm push functions via a mobile APP.
[0017] In one or more embodiments of this utility model, the exhaust pipe is located at the highest point of the main water supply pipeline.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0024] like Figure 1 As shown, a water supply main pipeline pumping control system according to one embodiment of the present invention includes a 4G three-phase remote switch 20, a pipeline pump 40, a first time delay relay 10, a second time delay relay 60, a three-phase relay 30, a self-resetting electric ball valve 70, an exhaust pipe, a pipeline liquid level sensor 80, an intermediate relay 90, a 220V to 24V transformer 50, a pipeline pressure gauge, and a monitoring camera.
[0025] The 4G three-phase remote switch 20 is connected to the pipeline level sensor 80, intermediate relay 90, first time delay relay 10 and second time delay relay 60 respectively through the 220V to 24V transformer 50. The normally open contact a of the intermediate relay 90 is connected to the normally open contact h of the first time delay relay 10. The normally open contact b of the intermediate relay 90 is connected to the neutral wire N and the coil neutral wire of the three-phase relay 30. The contact g of the first time delay relay 10 is connected to the coil live wire of the three-phase relay 30.
[0026] The pipeline level sensor 80 is equipped with a four-wire output interface, consisting of a yellow wire 101, a blue wire 102, a black wire 103, and a brown wire 104. The yellow wire 101 is connected to the negative terminal of the intermediate relay 90. The blue wire 102 and the black wire 103 are both connected to the negative terminal of the 220V to 24V transformer 50. The negative terminal of the 220V to 24V transformer 50 is also connected to the d-contact of the second time-delay relay 60 and the i-contact of the first time-delay relay 10.
[0027] Brown wire 104 is connected to the positive terminal of 220V to 24V transformer 50. The positive terminal of 220V to 24V transformer 50 is also connected to the positive terminal of intermediate relay 90 and the c and e contacts of second time delay relay 60. The f contact of second time delay relay 60 is connected to the negative terminal of self-resetting electric ball valve 70.
[0028] When the pipeline level sensor 80 detects that the water level has reached the set threshold, the intermediate relay 90 is activated. The normally open contact a of the intermediate relay 90 is connected in series with the normally open contact h of the first time delay relay 10 to form a double interlock control circuit. Only after the self-resetting electric ball valve 70 is completely closed and the water level is normal can the three-phase relay 30 be energized to start the pipeline pump 40.
[0029] Preferably, the first delay relay 10 and the second delay relay 60 are adjustable time relays, with a delay range adjustable from 5 to 300 seconds. In practical applications, the second delay range is set to close after 10 seconds, which is the time it takes for the self-resetting electric ball valve to fully open. After power failure, the self-resetting electric ball valve will self-reset within 10 seconds. The first delay is set to open after 20 seconds, meaning that the pipeline pump automatically starts when the self-resetting electric ball valve is fully closed.
[0030] The self-resetting electric ball valve 70 is installed on the vent pipe and controlled by the second time-delay relay 60. The pipeline pressure gauge is installed at the outlet of the pipeline pump 40, and the monitoring camera is aimed at the pipeline pressure gauge and the outlet of the vent pipe. The vent pipe is located at the highest point of the main water supply pipeline, and the outlet is equipped with a transparent acrylic observation window.
[0031] In addition, the surveillance camera is a network camera with night vision capability, which shares a communication module with the 4G three-phase remote switch 20 to achieve remote video monitoring. The 4G three-phase remote switch 20 integrates an IoT communication module, supporting remote power control, status monitoring, and alarm push functions via a mobile APP.
[0032] Preferably, the opening action of the self-resetting electric ball valve 70 takes precedence over the start of the pipeline pump 40, and a predetermined closing time is set by the second time delay relay 60.
[0033] When adding water to the reservoir, the water operator sends a power-on command to the 4G three-phase remote switch 20 via a mobile app. First, the self-resetting electric ball valve 70 connected to the exhaust pipe is opened. When the pipeline level sensor 80 detects water in the pipeline, the coil switch of the three-phase relay 30 is activated. The time relay connected in series with the intermediate relay 90 activates after the self-resetting electric ball valve 70 is fully closed. Only when all the above conditions are met can power be supplied to the pipeline pump 40 for pumping. Through a monitoring camera, it is possible to observe whether water is coming out of the exhaust pipe and hear the sound of water flow. It is also possible to observe whether the pointer of the pipeline pressure gauge is stable. If it swings back and forth, it indicates that the pumping is abnormal, and the 4G three-phase remote switch 20 needs to be turned off and restarted later.
[0034] The water supply main pipeline pumping control system of this utility model adopts a manual + intelligent control method, which avoids the pipeline pump running dry due to no water in the water supply pipeline in the system controlled by time-controlled switches, and ensures that the pipeline pump pumps normally pump water. It does not require supervision and the operation status can be checked anytime and anywhere by mobile phone, thus freeing up labor.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
