[0029] As Figure 1 shown, an intelligent security system for a drinking water room and a water supply pump room includes a detection device installed at the entrance of the drinking water room 1 and a control cabinet 2 installed in the drinking water room 1;

[0030] The detection device includes a plurality of detection switches 3 connected in parallel and all arranged at the entrance, and the detection switches 3 are used to detect illegal intrusion of personnel into the drinking water room 1 through the entrance;

[0031] The control cabinet 2 includes a water supply control circuit, and the detection switch 3 is connected to the water supply control circuit;

[0032] Among them, when any one of the plurality of detection switches 3 is disconnected, the water supply control circuit controls the water pump to stop working, and controls the inlet solenoid valve 7 on the inlet pipe 6 and the outlet solenoid valve 8 on the outlet pipe 5 to close, so as to control the closing of the inlet pipe 6 and the outlet pipe 5.

[0033] It should be noted that when any one of the plurality of detection switches 3 is disconnected, that is, when illegal intrusion is activated, the water supply control circuit first controls the water pump to stop working immediately. Then, after a few seconds of delay, the water supply control circuit controls the closing of the inlet solenoid valve 7 and the outlet solenoid valve 8 to control the closing of the inlet pipe 6 and the outlet pipe 5 of the drinking water tank 4. Then, the remote alarm 9 alarms the person in charge of the pump room. After taking a water sample to the scene for testing and confirming the safety of the water sample manually, the protection circuit is manually reset through the 4G switch SB in the control cabinet. At this time, the inlet solenoid valve 7 and the outlet solenoid valve 8 are opened, the water pump works normally, and the water supply resumes normal.

[0034] The utility model directly applies electrical automation components, solenoid valves, and the Internet of Things platform to create a domestic water supply room and a rural water pump room to protect the drinking water tank and the water pump well, and prevent illegal intrusion and poisoning of the security system.

[0035] The utility model directly applies a long-distance infrared photoelectric switch, electrical automation components, solenoid valves, and an Internet of Things platform to create a domestic water supply room and a rural water pump room, which protect the drinking water tank 4 and the water pump well to prevent illegal intrusion and poisoning into the security system.

[0036] The utility model adopts an intelligent automation protection system for the drinking water room 1, which can detect whether there is illegal intrusion, and when an intrusion occurs, it can close all booster pump groups, deep pump groups related to the drinking water tank 4 or the drinking water well, and the connected water supply pipelines, and then send an alarm to the supervisors through a platform built by the Internet of Things, such as a mobile APP or a computer program. After an intrusion occurs, the supervisors can first notify professional personnel to detect whether the water quality is safe, and then decide whether to reset the security system and resume water supply.

[0037] The utility model will use three groups of parallel long-distance infrared photoelectric switches at each entrance door, window, etc. of the drinking water room 1. Once a person enters under the operating state of the system, one or several long-distance infrared photoelectric switches will be disconnected. After the long-distance infrared photoelectric switch is disconnected, the signal will be transmitted to the security control cabinet through electrical components such as intermediate relays and AC contactors. After receiving the signal, the control cabinet will immediately disconnect the output circuit related to the water pump to prevent subsequent solenoid valve actions from causing pipeline overpressure, and control the solenoid valves set in each pipeline to perform a closing action to block all pipelines to prevent pollutants from flowing to other places through the pipelines. And it will cause the data collector to send an alarm to the supervisors through a platform built by the Internet of Things, such as a mobile APP or a computer program. After the supervisors find the problem, they will dispatch personnel to the site for investigation, extract and detect the water sample, and remotely reset the security system after confirming that the water sample meets the drinking standard. At this time, all solenoid valves will be opened first, and then the water pump will be restarted. At this time, the water supply will return to normal.

[0038] The advantages of the utility model compared with the traditional inspection and security of the water pump room are: low cost, fast response speed, not affected by the quality of personnel, able to quickly and effectively isolate the water source where an accident occurs, and reduce subsequent losses. At the same time, it is also convenient for security personnel to conduct safety monitoring of the drinking water room.

[0039] In this embodiment, as Figure 1As shown in the figure, at the entrance of the drinking water room 1, a set of detection switches consisting of three remote infrared photoelectric switches is provided. This can also be set at multiple entrances, and this figure is just an example. Once someone illegally enters from the entrance, the photoelectric switches will detect it, and the control cabinet will close the booster pump, the inlet solenoid valve 7, the outlet solenoid valve 8, disconnect the drinking water tank 4 from the water pipe network. At the same time, the remote alarm 9 will alarm the security personnel. After the security personnel arrive at the scene to confirm safety, they will take a water sample for inspection. After confirming the safety of the water sample, the anti-illegal intrusion and poisoning security system will be remotely reset to restore normal water supply.

[0040] In this embodiment, the detection switch 3 is a remote infrared photoelectric switch.

[0041] In this embodiment, the number of the detection devices is at least one, and the number of at least one detection device corresponds one-to-one to the number of entrances of the drinking water room 1.

[0042] In this embodiment, the detection device includes three detection switches 3, and the three detection switches 3 are detection switch SQ1, detection switch SQ2, and detection switch SQ3.

[0043] In this embodiment, the control cabinet 2 further includes a remote alarm 9, and the remote alarm 9 is connected to the water supply control circuit; wherein, when any one of the multiple detection switches 3 is disconnected, the water supply control circuit controls the remote alarm 9 to alarm.

[0044] In this embodiment, the water supply control circuit includes an intermediate relay KA1, an inlet solenoid valve YV1, and an outlet solenoid valve YV2;

[0045] The detection switch SQ1, the detection switch SQ2, and the detection switch SQ3 are connected in parallel between the live wire L of the AC power supply and the intermediate relay KA1. The normally closed contact KT of the intermediate relay KA1 is connected between the live wire L and the coil of the intermediate relay KA1. The normally open contacts of the intermediate relay KA1 are respectively connected to the inlet solenoid valve YV1, the outlet solenoid valve YV2, and the remote alarm B1; the normally closed contact of the intermediate relay KA1 is connected to the water supply manual / automatic control circuit;

[0046] The inlet solenoid valve YV1 and the outlet solenoid valve YV2 are respectively connected to the normally open contacts of the intermediate relay KA1;

[0047] The remote alarm B1 is connected to the normally open contact of the intermediate relay KA1.

[0048] Wherein, the inlet solenoid valve YV1 is the inlet solenoid valve 7, the outlet solenoid valve YV2 is the outlet solenoid valve 8, and the remote alarm B1 is the remote alarm 9.

[0049] As Figure 2 shown, when a person invades from the entrance, the detection switches SQ1, SQ2, or SQ3 will close when they sense someone breaking in. After the detection switches close, the coil of the intermediate relay KA1 will be energized. Then, the normally open contact of KA1 will close and the normally closed contact of KA1 will open. After the normally open contact of KA1 closes, a self-locking circuit of KA1 will be formed, and the water inlet solenoid valve YV1 will be started. The water outlet solenoid valve YV2 disconnects the drinking water tank from the water pipe network, and the remote alarm 9 will be powered on to alarm and remind the security personnel. After the normally closed contact of KA1 opens, both the manual and automatic water supply circuits will be disconnected, and the water pump will stop running. After the security personnel confirm the safety of the site and the water sample, they can remotely disconnect the 4G switch SB4G to reset the anti-illegal intrusion and poisoning security system. During the reset process, the relay will be delayed in energizing, so the solenoid valve will open first and the water pump will start later to prevent overpressure in the pipeline and restore normal water supply.

[0050] In this embodiment, the water supply control circuit further includes a 4G switch, and the 4G switch is connected to the coil of the intermediate relay KA1 through the normally open contact of the intermediate relay KA1.

[0051] It should be noted that Figure 3 is the circuit schematic diagram of the constant pressure water supply circuit in the prior art provided by the embodiment of the present application. As Figure 3 shown, when the main contactor KM2 of the existing constant pressure water supply control main circuit is energized, it is automatically for variable frequency constant pressure control, and when the manual KM1 is energized, it is for on-site button control. And a voltmeter and an ammeter are configured.

[0052] The technical features of the above embodiments can be combined arbitrarily as long as there is no contradiction in the combination of these technical features. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered to be within the scope described in this specification.
