Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0018] See also Figure 1-2 , the utility model provides a technical solution:

[0019] Embodiment 1: A monitoring control system comprises a control panel, wherein a main control module is installed in the control panel, a communication module is also installed in the control panel, and a gas leakage sensor 7, several alarms 3, a temperature sensor, an electric energy unit, an upper liquid level sensor 4 and a lower liquid level sensor 5 are arranged outside the control panel;

[0020] Specifically, multiple alarms 3 are provided for different alarm contents;

[0021] 1. Water level upper limit alarm When the water level reaches the upper limit, the liquid level sensor detects that the water level has reached the upper limit, and the water is not drained in time, the local sound and light buzzer alarms, and the remote monitoring computer alarms at the same time.

[0022] 2. Water shortage and leakage alarm

[0023] A liquid level sensor is set at the bottom of the drainer to monitor the water level of the drainer. When the water level drops to the alarm level, an alarm will be sounded in the remote monitoring computer to provide early warning when there is water shortage.

[0024] 3. Gas leak alarm

[0025] A gas alarm 3 is arranged near the drainer to monitor the gas concentration around the drainer. When the concentration exceeds the standard, a local sound and light buzzer alarms, and an alarm is also sounded on a remote monitoring computer.

[0026] 4. External power supply abnormality alarm

[0027] The drainer is powered by UPS uninterruptible power supply. When the external power supply stops, the local sound and light buzzer alarms and the remote monitoring computer alarms at the same time.

[0028] 5. Low temperature alarm of drainer body

[0029] When the electric heating of the drainer body fails and the temperature is lower than 5 degrees, the local sound and light buzzer will alarm, and the remote monitoring computer will also alarm.

[0030] The electric energy unit includes a battery, an electric energy controller, a current sensor and a power supply. The power supply is connected to the current sensor, the current sensor is connected to the main control module, the electric energy controller is bidirectionally electrically connected to the main control module, and the electric energy controller is connected to the battery.

[0031] The control panel is connected to the main control module, the communication module is bidirectionally electrically connected to the main control module, the main control module is respectively connected to a plurality of the alarms 3, the gas leakage sensor 7, the temperature sensor, the upper liquid level sensor 4 and the lower liquid level sensor 5 are respectively connected to the main control module.

[0032] Embodiment 2: An intelligent gas drainer of a monitoring and control system comprises a gas pipeline 1, a drain box body 2 is provided at the bottom of the gas pipeline 1, a gas inlet structure is provided between the drain box body 2 and the gas pipeline 1, a plurality of alarms 3 are installed on the upper side of the drain box body 2, an overflow control structure is installed on the side of the drain box body 2 away from the gas inlet structure, an upper liquid level sensor 4 and a lower liquid level sensor 5 are respectively inserted on the side wall of the drainer body and located on the upper and lower sides of the drain control structure, a protective cover 6 is installed outside the drain control structure, a gas leakage sensor 7 is embedded at the bottom of the protective cover 6, and a control panel is embedded on the outer side of the drain box body 2;

[0033] Specifically, when the external power supply is cut off due to power outage, line maintenance, or unexpected failure, the system will automatically switch to UPS power supply. This drainer uses a high-power lithium battery, which can provide continuous power supply for 7-8 days in winter and 9-10 days in summer. If the external power supply stops, the sound and light alarm buzzer on the panel of the explosion-proof box 16 will sound an alarm;

[0034] When the water level reaches the upper line and the water cannot be discharged, the sound and light alarm buzzer on the panel of the explosion-proof box 16 will sound an sound and light alarm.

[0035] When the electric heating of the drainer fails and the temperature is lower than 5 degrees, the local sound and light buzzer alarms, and the remote alarm is also activated. When the outdoor temperature is higher than +10 degrees, the power supply of the heating cable is automatically cut off, which can effectively extend the service life of the heating cable.

[0036] Embodiment three: The gas introduction structure includes a primary valve 8, which is connected to the gas pipeline 1. An air intake pipe 9 is installed at the lower side of the primary valve 8, and the air intake pipe 9 is inserted into the drainage box body 2. A detection port 10 and an electric explosion-proof cut-off secondary valve 11 are installed in sequence on the air intake pipe 9 and at the lower side of the primary valve 8. The electric convenient cut-off secondary valve is connected to the main control module.

[0037] The drainage box body 2 is provided with a water inlet 12 and an air inlet 13 on the left and right sides of the air inlet pipe 9, respectively. A sewage hand hole 14 and a sewage hole 15 are provided on the lower side of the side wall of the drainage box body 2 in sequence from top to bottom. An explosion-proof box 16 is provided inside the drainage box body 2.

[0038] Specifically, the secondary valve and drain outlet of the drainer will be automatically closed when a gas leak alarm occurs. The upper secondary valve of the drainer uses an electric shut-off valve, and the drain outlet uses an electric 304 stainless steel explosion-proof electric ball valve 18. When the CO gas sensor detects a leak alarm, the system automatically closes the upper electric secondary valve and the drain outlet electric ball valve at the same time. After the maintenance personnel go to the site for inspection and processing, the CO gas sensor cannot detect any leaks, and the alarm will be automatically released.

[0039] Embodiment 4: The overflow control structure includes an overflow pipe 17, which is inserted on the side wall of the drainage box body 2. The overflow pipe 17 is in the shape of a "door", and the port of the overflow pipe 17 located in the drainage box body 2 is lower than the port on the outside. The port on the outside of the overflow pipe 17 passes through the protective cover 6. An explosion-proof electric ball valve 18 is installed on the overflow pipe 17, and the explosion-proof electric air valve is connected to the main control module. The position of the lower liquid level sensor 5 is higher than the inner and outer ends of the overflow pipe 17. A drain pipe 19 is inserted on the outside of the drainage box body 2 and located at the overflow pipe 17. A funnel-shaped water inlet is opened on the top of the drain pipe 19. The water inlet is located directly below the outer port of the overflow pipe 17, and the water inlet end of the drain pipe 19 is higher than the inner port of the overflow pipe 17.

[0040] Specifically, the pressure of gas pipeline 1 is unstable, and sometimes overpressure occurs. Our intelligent drainer uses explosion-proof electric ball valve to control drainage, and the maximum pressure resistance can reach more than 0.6MPa, so it is not affected by gas pressure;

[0041] This intelligent drainer does not use the old water self-sealing principle, but relies on a liquid level sensor to control the water level. There is no problem of water shortage and no need to add water.

[0042] When the water level drops to the limit, the liquid level sensor detects that the water level has dropped to the limit and automatically starts the explosion-proof electric-controlled ball valve to close the drain outlet, so there is no leakage problem.
