[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this utility model without creative efforts shall fall within the protection scope of this utility model.

[0036] The following will, in conjunction with the accompanying drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] To solve the technical problems existing in the prior art, an embodiment of the present utility model provides a safety production management system for a gas pressure regulating and metering cabinet.

[0038] See Figure 1 , which shows a block diagram of a safety production management system for a gas pressure regulating and metering cabinet according to an embodiment of the present utility model.

[0039] As Figure 1 shown, a safety production management system for a gas pressure regulating and metering cabinet includes:

[0040] a control module, a combustible gas detection module, a fire detection module, a pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet, a pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, a pneumatic fully open valve for the pressure regulating and metering cabinet to vent, and a fire extinguishing module;

[0041] Among them, the combustible gas detection module is connected to the control module and transmits a gas leakage signal to the control module;

[0042] The fire detection module is connected to the control module and transmits a fire signal to the control module;

[0043] The control module is respectively connected to the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet, the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, the pneumatic fully open valve for the pressure regulating and metering cabinet to vent, and the fire extinguishing module, and controls the working states of the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet, the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, the pneumatic fully open valve for the pressure regulating and metering cabinet to vent, and the fire extinguishing module respectively.

[0044] It can be understood that the combustible gas detection module is used to detect the gas volume in the gas pressure regulating and metering cabinet. When the gas volume exceeds the safety value, it indicates that there is a gas leakage phenomenon at present, and the combustible gas detection module sends a gas leakage signal to the control module.

[0045] It can be understood that the fire detection module is used to detect whether there is a fire in the gas pressure regulating and metering cabinet. If there is a fire, it sends a fire signal to the control module.

[0046] It is understandable that the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet and the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet are respectively arranged at the gas inlet and outlet of the pipeline in the pressure regulating and metering cabinet. Opening the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet allows gas to enter the pipeline in the pressure regulating and metering cabinet, while closing it prohibits gas from entering. Opening the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet allows gas to be output from the pipeline in the pressure regulating and metering cabinet, and closing it prohibits gas from being output from the pipeline in the pressure regulating and metering cabinet.

[0047] It is understandable that a blow-off pipe is connected to the pipeline in the pressure regulating and metering cabinet, and the fully open pneumatic blow-off valve of the pressure regulating and metering cabinet is arranged on the blow-off pipe. When the fully open pneumatic blow-off valve of the pressure regulating and metering cabinet is opened, gas can be discharged through the blow-off pipe.

[0048] When a leakage occurs in this system, the upstream and downstream of the pressure regulating and metering cabinet can be urgently cut off, and at the same time, the gas in the cabinet can be discharged. In the early stage of a fire or the generation of combustible smoke, the pre-stored fire extinguishing module can be used for early automatic fire extinguishing to achieve safe production management without unattended operation.

[0049] It should be noted that the control module, combustible gas detection module, and fire detection module used in this utility model should have explosion-proof functions. For example, the control module can be an explosion-proof RTU (Remote Terminal Unit), the combustible gas detection module can be an explosion-proof combustible gas detector, the fire detection module can be an explosion-proof smoke detector and fire alarm, and the fire extinguishing module can be a fire extinguishing device, and the fire extinguishing device also has explosion-proof functions.

[0050] Next, an example of the emergency treatment process of this system for gas leakage is provided.

[0051] As Figure 2 shown, the explosion-proof combustible gas detector detects the leakage signal and transmits it to the explosion-proof RTU. The explosion-proof RTU controls the emergency cut-off of the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet and the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, and then the explosion-proof RTU controls the emergency full opening of the fully open pneumatic blow-off valve of the pressure regulating and metering cabinet, and transmits it to the (gas distribution station) control center station through 4G and 5G signals.

[0052] Next, an example of the emergency treatment process of this system for a fire is provided.

[0053] As Figure 3 shown, the explosion-proof fire and smoke alarm detects the fire signal and transmits it to the explosion-proof RTU. The explosion-proof RTU controls the emergency cut-off of the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet and the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, and then the explosion-proof RTU controls the emergency full opening of the fully open pneumatic blow-off valve of the pressure regulating and metering cabinet, and the explosion-proof RTU controls the start of the fire extinguishing device, and transmits it to the (gas distribution station) control center station through 4G and 5G signals.

[0054] In some feasible embodiments, based on the foregoing solution, it further includes: a monitoring module;

[0055] The monitoring module is connected to the control module.

[0056] It can be understood that the monitoring module is used to monitor the situation inside the gas pressure regulating and metering cabinet in real time and transmit the monitoring data to the control module.

[0057] In some feasible embodiments, based on the foregoing solution, the monitoring module adopts an explosion-proof camera.

[0058] Such as Figure 4 shown, the explosion-proof camera is equipped with an SD memory card, and the data monitored by the explosion-proof camera in real time is transmitted to the control module, and the control module then remotely transmits it to the (gas distribution station) control center station through 4G or 5G signals.

[0059] In some feasible embodiments, based on the foregoing solution, it further includes: a flow detection module;

[0060] The flow detection module is connected to the control module.

[0061] In some feasible embodiments, based on the foregoing solution, the flow detection module adopts an explosion-proof flowmeter.

[0062] Such as Figure 4 shown, the explosion-proof flowmeter is used to detect the flow situation in the pipeline of the gas pressure regulating and metering cabinet and transmit the flow data to the control module, and the control module then remotely transmits it to the (gas distribution station) control center station through 4G or 5G signals.

[0063] In some feasible embodiments, based on the foregoing solution, it further includes: a pressure detection module;

[0064] The pressure detection module is connected to the control module.

[0065] In some feasible embodiments, based on the foregoing solution, the pressure detection module adopts an explosion-proof pressure transmitter.

[0066] Such as Figure 4 shown, the pressure detection module is used to detect the pressure situation in the pipeline of the gas pressure regulating and metering cabinet and transmit the pressure data to the control module, and the control module then remotely transmits it to the (gas distribution station) control center station through 4G or 5G signals. When the pressure is too high or too low, the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet and the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet can be closed through the control module.

[0067] In some feasible embodiments, based on the foregoing solution, it further includes: a differential pressure generator and a storage battery;

[0068] The differential pressure generator generates electricity based on the pipeline differential pressure inside the pressure regulating and metering cabinet;

[0069] The differential pressure generator is connected to the storage battery;

[0070] The storage battery is respectively connected to the control module, the combustible gas detection module, the fire detection module, the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet, the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, the fully open pneumatic relief valve of the pressure regulating and metering cabinet, the fire extinguishing module, the monitoring module, the flow rate detection module and the pressure detection module.

[0071] It should be noted that both the differential pressure generator and the storage battery need to have explosion-proof functions.

[0072] Such as Figure 5 , Figure 6 As shown, the differential pressure generator is connected in parallel to the pipeline in the pressure regulating and metering cabinet, generates electricity by using the differential pressure, and the generated current is transmitted to the explosion-proof USP storage battery for storage. The storage battery is then respectively connected to the explosion-proof RTU, the explosion-proof combustible gas detector, the explosion-proof smoke detector, the fire alarm, the body-type fire extinguishing sheet, the pneumatic cut-off valve at the inlet of the pressure regulating and metering cabinet, the pneumatic cut-off valve at the outlet of the pressure regulating and metering cabinet, the fully open pneumatic relief valve of the pressure regulating and metering cabinet, the explosion-proof flow meter, the explosion-proof pressure transmitter and the explosion-proof camera to provide power for these devices, so that the system does not need to be externally powered.

[0073] Since the system uses the differential pressure of the pipeline in the pressure regulating and metering cabinet to generate electricity, which is a clean energy source, it has the advantages of longer power generation time and being unaffected by weather compared with solar energy and wind energy, providing a power supply guarantee for the safety production management system of the pressure regulating and metering cabinet.

The present invention is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include common general knowledge or conventional technical means in the technical field not disclosed by the present invention. It should be understood that the present invention is not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
