Description

Technical Field

[0001] The utility model belongs to the technical field of remote control, and in particular relates to a remote closing device for a single well in a water source. Background Art

[0002] At present, most of the power supply for single wells in tap water sources is public lines, which sometimes cause power outages due to bad weather, construction and other reasons. The inability of relevant technicians to obtain power outage information in the first place will cause delays in water supply scheduling and emergency repairs; and because the low-voltage side circuit breaker has a loss of pressure tripping protection, each time the high-voltage side power supply is restored to normal, the technicians need to go to the site to manually operate the low-voltage side circuit breaker to close the switch and supply power to complete the power supply restoration of the equipment; in addition, most of the single wells in the water source are distributed around the urban area, which is far away from the urban area, which further increases the delay in power supply restoration.

[0003] In the prior art, a control device for an intelligent circuit breaker is disclosed with the publication number CN216288267U. The device is centered on a single-chip microcomputer and is equipped with power supply, metering, motor drive and energy storage modules to realize intelligent control of the reclosing circuit breaker. However, the motor driven by the single-chip microcomputer often has the problem of insufficient voltage. The use of energy storage modules to supply power after power failure makes this shortcoming more prominent.

[0004] To this end, the utility model provides a single-well remote closing device for a water source, which also has functions such as power outage alarm, temperature and humidity alarm, etc., and can be used to quickly restore water source power supply to ensure continuous and stable operation of water intake point equipment.

[0008] A temperature and humidity switch KA4 is connected between the monitoring module and the remote control switch, and the remote control switch is also connected to a temperature sensor and a humidity sensor in parallel; the temperature sensor and the humidity sensor are installed in the field operation cabinet and control the opening and closing of the temperature and humidity switch KA4. The temperature sensor and the humidity sensor are responsible for monitoring the temperature and humidity in the field operation cabinet, and control the opening and closing of the temperature and humidity switch KA4 according to the set temperature and humidity thresholds.

[0009] The utility model also includes an opening control module. The closing control module is connected in parallel with the opening control module. The opening control module includes an opening button SB1, an intermediate relay normally open contact KA1 and an opening coil K1 which are connected.

[0010] The monitoring module adopts air circuit breaker.

[0011] The remote switch communicates with the mobile terminal via a built-in 4G wireless network card, and is powered by a battery. The 4G wireless network card and built-in battery enable the remote switch to maintain communication with the mobile terminal even in the event of an external power outage.

[0012] The utility model has the following beneficial effects:

[0015] Figure 2 This is the circuit schematic diagram of the utility model.

[0016] Among them: 1. On-site operation cabinet; 2. Remote control switch; 3. Temperature sensor; 4. Humidity sensor; 5. Low-voltage main circuit breaker; 6. Closing coil; 7. Closing button; 8. Monitoring module. DETAILED DESCRIPTION

[0017] like Figure 1 and Figure 2As shown, a remote closing device for a single well in a water source area comprises an on-site operation cabinet 1, a monitoring module 8 and a control module, wherein the control module comprises a remote control switch 2 and a closing control module connected in parallel; the remote control switch 2 is connected to a mobile terminal for communication; the closing control module comprises a connected switch module, an intermediate relay normally closed contact KA2 and a closing coil 6; the switch module comprises a closing button 7 and a remote control switch normally open contact KA3 connected in parallel; one end of the monitoring module 8 is connected to a low-voltage main circuit breaker 5, and the other end is connected to the remote control switch 2; the remote control switch 2, the low-voltage main circuit breaker 5 and the closing button 7 are installed in the on-site operation cabinet, and the closing coil 6 is arranged inside the low-voltage main circuit breaker 5.

[0018] A temperature and humidity switch KA4 is connected between the monitoring module 8 and the remote switch 2, and the remote switch 2 is also connected to a temperature sensor 3 and a humidity sensor 4 in parallel; the temperature sensor 3 and the humidity sensor 4 are both installed in the field operation cabinet 1, and control the opening and closing of the temperature and humidity switch KA4. The temperature sensor 3 and the humidity sensor 4 are responsible for monitoring the temperature and humidity in the field operation cabinet 1, and control the opening and closing of the temperature and humidity switch KA4 according to the set temperature and humidity thresholds.

[0019] The utility model also includes an opening control module. The closing control module is connected in parallel with the opening control module. The opening control module includes an opening button SB1, an intermediate relay normally open contact KA1 and an opening coil K1 which are connected.

[0020] The monitoring module 8 adopts an air circuit breaker.

[0021] The remote control switch 2 is connected to the mobile terminal for communication via a built-in 4G wireless network card, and a battery is provided inside the remote control switch 2 for power supply. The 4G wireless network card and the built-in battery enable the remote control switch 2 to maintain communication with the mobile terminal even in the event of an external power outage.

[0022] When the power is off, the low-voltage main circuit breaker 5 loses power and disconnects, and the remote control switch 2 sends a power-off alarm signal to the mobile terminal; when the power is restored, the mobile terminal sends a closing signal to the remote control switch 2, and the remote control switch 2 controls the normally open contact KA3 of the remote control switch to close so that the closing coil 6 is energized, and the closing coil 6 is energized to control the low-voltage main circuit breaker 5 to close and realize remote closing;

[0023] Specifically, on the one hand, when the transformer at the single well site of the water source loses power, the low-voltage main circuit breaker 5 loses power and disconnects, and the air circuit breaker cannot detect the low-voltage side voltage signal and transmits the information to the remote control switch 2. On the other hand, when the temperature sensor 3 and the humidity sensor 4 detect that the temperature and humidity in the on-site operation cabinet 1 are too high, the temperature and humidity switch KA4 is disconnected, and the remote control switch 2 cannot detect the voltage signal; when the remote control switch 2 cannot detect the voltage signal, the remote control switch 2 sends a power outage alarm message to the mobile terminal through the 4G wireless network card. After receiving the alarm message, the technician consults the power supply department about the cause of the power outage: if it is an external line power outage, the technician can wait for the external line power supply to be restored and send a closing signal to the remote control switch 2 through the mobile terminal. After the remote control switch receives the command, the normally open contact KA3 of the remote control switch in the switch module is closed, the closing coil 6 is energized, and the low-voltage main circuit breaker 5 is closed to realize the remote closing operation; if it is not an external line power outage, the technician can go to the site to inspect and repair the equipment as soon as possible to restore power supply as soon as possible, thereby improving the efficiency of troubleshooting and ensuring the stable operation of the water system.
