Description

Technical Field

[0001] This utility model relates to the field of industrial Internet of Things (IoT) explosion-proof gas carbon emission monitoring technology, specifically an explosion-proof carbon emission monitoring and acquisition module based on NB-IoT. Background Technology

[0002] The existing carbon emission monitoring modules lack component synergy, with most devices only capable of single gas detection functions. They lack integrated design with core components such as air pumps, pneumatic valves, and alarm devices, resulting in a large overall size and complex installation of the monitoring system. Furthermore, additional control units are required to achieve closed-loop management of detection, transmission, early warning, and control, increasing the equipment procurement costs and maintenance difficulties for enterprises. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an explosion-proof carbon emission monitoring and acquisition module based on NB-IoT, which solves the problems of high equipment procurement costs and maintenance difficulties.

[0005] (II) Technical Solution

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an explosion-proof carbon emission monitoring and acquisition module based on NB-IoT, comprising: a main pipe, both ends of which are fixedly connected to flanges; a tee pipe fixedly connected to the main pipe via the flanges; a tee pneumatic ball valve penetrating the outer wall of the tee pipe; an exhaust pipe penetrating one end of the outer wall of the tee pipe via a flange; and a diversion chamber penetrating the other end of the outer wall of the tee pipe via a flange. A branch pipe is penetrating the outer wall of the diversion chamber away from the tee pipe via a flange. The cooperation between the tee pipe and the tee pneumatic ball valve allows for flexible adjustment of the gas flow path, improving the module's adaptability to different monitoring scenarios. The exhaust pipe ensures timely discharge of normally monitored gas; the diversion chamber buffers and stabilizes the gas, reducing the interference of gas pressure fluctuations on subsequent monitoring stages; and the branch pipe enables reasonable gas diversion, providing support for subsequent multi-unit monitoring or processing.

[0007] Preferably, a reinforcing sleeve is fixedly connected to the outer wall of the main pipe, and an air pump is fixedly connected to the outer wall of the reinforcing sleeve in the middle. The suction end of the air pump passes through the reinforcing sleeve and extends into the interior of the main pipe. Three branch pipes are provided. The application of the air pump provides stable power for the gas to be transported from the main pipe to the monitoring stage, ensuring that the gas to be monitored can reach the monitoring components smoothly, avoiding monitoring delays or failures due to insufficient gas flow power, and improving the timeliness of monitoring. The three branch pipes increase the selection of gas transport paths, enabling the module to simultaneously meet the gas requirements of multiple subsequent units, improving the module's multifunctionality and flexibility of use, adapting to more complex monitoring and processing scenarios, and expanding the application range of the module. At the same time, the four-in-one gas detector transmits the detected gas concentration value to the PLC controller via wires as an electrical signal. The PLC controller receives the signal, performs calculations and comparisons, and when the gas concentration value exceeds the preset value, the PLC controller transmits a control command via wires as an electrical signal to the three-way pneumatic ball valve. The three-way pneumatic ball valve executes the command, closing the discharge pipe and connecting the branch pipes with the main pipe, achieving the effect of diverting and reducing the gas concentration value.

[0008] Preferably, the outlet of the air pump is connected to a delivery pipe via a flange. A four-in-one gas detector is connected to the outer wall of the delivery pipe at the end furthest from the air pump via the flange. A connection hole is provided on the outer wall of the four-in-one gas detector at the end furthest from the delivery pipe. The four-in-one gas detector has a built-in NB-IoT module. When the air pump extracts the gas to be monitored from the main pipe, the gas is delivered through the air pump outlet via the flange-connected delivery pipe to the four-in-one gas detector at the other end of the delivery pipe. Upon receiving the gas, the four-in-one gas detector immediately detects and analyzes various related components in the gas, obtaining key data. If the functionality of the four-in-one gas detector needs to be expanded, such as by adding data storage or connecting to an external display device, corresponding auxiliary equipment can be connected through the connection hole on the outer wall furthest from the delivery pipe. Simultaneously, after detection, the built-in NB-IoT module of the four-in-one gas detector processes the detected gas data according to a set method and remotely transmits it to a designated monitoring platform or terminal device via the NB-IoT network, enabling staff to remotely obtain gas monitoring data in real time.

[0009] Preferably, an alarm light is installed on the side of the air pump away from the four-in-one gas detector. The outer wall below the alarm light is fixedly connected to a reinforcing sleeve fitted onto the outer wall of the main pipe. A PLC controller is fixedly connected to the outer wall of the main pipe. The PLC controller controls the four-in-one gas detector, air pump, alarm light, and three-way pneumatic ball valve through wires. As the control core of the module, the PLC controller realizes centralized control of the four-in-one gas detector, air pump, alarm light, and three-way pneumatic ball valve, eliminating the need for manual operation of each component, simplifying the operation process, reducing manual operation costs and the probability of operational errors. Through the coordinated control of each component by the PLC controller, a rapid response can be made in the event of abnormalities, and the operating status of each component can be adjusted in a timely manner to control the development of abnormalities. The alarm light can issue a warning signal in a timely manner when the module malfunctions, making it easy for staff to quickly detect abnormalities and take countermeasures, reducing safety risks or monitoring data deviations caused by failure to handle abnormalities in a timely manner. The model of the four-in-one gas detector is LBMD4X, the model of the air pump is 4-HL, and the model of the alarm light is BLD2.

[0010] (III) Beneficial Effects

[0011] This invention provides an explosion-proof carbon emission monitoring and acquisition module based on NB-IoT. It has the following advantages:

[0012] (I) This explosion-proof carbon emission monitoring and acquisition module based on NB-IoT improves management convenience and scenario adaptability by relying on NB-IoT technology and flexible structure. The NB-IoT module built into the four-in-one gas detector transmits the detection data to the monitoring platform over a long distance. Staff can obtain data without on-site duty. The monitoring platform can centrally manage data from multiple modules, providing support for carbon emission control and realizing dynamic monitoring of carbon emission gases throughout the entire cycle. This reduces the cost and difficulty of manual management. The three-way pipe and the three-way pneumatic ball valve work together to adjust the gas flow path. The three pipes realize multi-path gas diversion, adapting to scenarios such as single monitoring and multi-unit synchronous monitoring. The module is connected to external equipment through flanges, making it easy to install and disassemble. It can be flexibly installed in different industrial scenarios without large-scale modification of existing equipment, thus improving scenario adaptability.

[0013] (II) This explosion-proof carbon emission monitoring and acquisition module based on NB-IoT improves monitoring efficiency through multi-component collaboration and enhances safety performance through hardware. On the one hand, the main pipe is sealed to the external equipment via a flange, and the gas pump draws gas from the main pipe and delivers it to the four-in-one gas detector through a sealed delivery pipe, reducing gas leakage and ensuring the detection parameters. The PLC controller receives data in real time and compares it with preset thresholds. In case of abnormality, it controls the three-way pneumatic ball valve to adjust the gas path and the alarm light to warn, realizing the linkage of collection, judgment and response, reducing the delay of manual intervention. On the other hand, the reinforced casing ensures the structural stability of the main pipe, improves the explosion-proof performance of the module, adapts to industrial explosion-proof environments, avoids safety accidents caused by equipment operation, and ensures the safety of monitoring data and on-site operations.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution for an explosion-proof carbon emission monitoring and acquisition module based on NB-IoT, including: a main pipe 1, with flanges 12 fixedly connected to both ends of the main pipe 1, a three-way pipe 11 fixedly connected to the main pipe 1 through the flanges 12, a three-way pneumatic ball valve 8 connected through the outer wall above the three-way pipe 11, an exhaust pipe 6 connected through the flange 12 at one end of the outer wall of the three-way pipe 11, a diversion chamber 7 connected through the flange 12 at the other end of the outer wall of the three-way pipe 11, and a branch pipe 13 connected through the flange 12 to the outer wall of the diversion chamber 7 away from the three-way pipe 11.

[0021] A reinforcing sleeve is fixedly connected to the outer wall of the main pipe 1. An air pump 4 is fixedly connected to the outer wall of the intermediate reinforcing sleeve. The suction end of the air pump 4 passes through the reinforcing sleeve and extends into the interior of the main pipe 1. Three branch pipes 13 are provided.

[0022] The air outlet of the air pump 4 is connected to the delivery pipe 10 through the flange 12. The outer wall of the delivery pipe 10 away from the air pump 4 is connected to the four-in-one gas detector 3 through the flange 12. The outer wall of the four-in-one gas detector 3 away from the delivery pipe 10 has a reserved connection hole. The four-in-one gas detector 3 has an NB-IoT module built in.

[0023] An alarm light 5 is installed on the side of the air pump 4 away from the four-in-one gas detector 3. The outer wall below the alarm light 5 is fixedly connected to the reinforcing sleeve that fits into the outer wall of the main pipe 1. A PLC controller 2 is fixedly connected to the outer wall of the main pipe 1. The PLC controller 2 controls the four-in-one gas detector 3, the air pump 4, the alarm light 5, and the three-way pneumatic ball valve 8 through wires.

[0024] In use, the device is connected to a suitable location via flange 12. The carbon emission-related gas to be monitored first enters the module's main pipe 1. The main pipe 1 forms a sealed connection with external equipment or pipelines through flanges 12 fixed at both ends, ensuring no leakage during gas transportation and achieving centralized gas collection. The collected gas then flows into a three-way pipe 11, which is connected to the main pipe 1 via flange 12. The three-way pipe 11 serves as the core component for gas diversion, and its outer wall is connected to a three-way pneumatic ball valve 8. The valve status can be adjusted according to actual monitoring needs, thereby changing the gas flow path. When it is not necessary to divert part of the gas... During deep monitoring, the three-way pneumatic ball valve 8 controls the gas flow to the discharge pipe 6 connected to one end of the three-way pipe 11 via the flange 12, so that the gas under normal monitoring is discharged in time. When multi-unit monitoring or processing of gas is required, the three-way pneumatic ball valve 8 guides the gas into the diversion chamber 7 connected to the other end of the three-way pipe 11 via the flange 12. The diversion chamber 7 acts as a buffer and pressure stabilizer for the incoming gas, reducing the interference of gas pressure fluctuations on subsequent monitoring links. Then, the gas is reasonably diverted through the three branch pipes 13 connected to the flange 12 via the outer wall of the diversion chamber 7, providing a stable gas source for subsequent multi-path monitoring or processing.

[0025] Simultaneously with the gas introduction, the air pump 4, fixedly connected to the reinforcing sleeve on the outer wall of the main pipe 1, starts working. The suction end of the air pump 4 penetrates the reinforcing sleeve and extends into the interior of the main pipe 1, enabling it to directly extract the gas to be monitored from the main pipe 1. This provides stable power for the gas delivery to the detection stage, avoiding monitoring delays or failures due to insufficient gas flow power. The gas extracted by the air pump 4 is sealed and transported through the delivery pipe 10 connected by the flange 12 at its outlet end. The end of the delivery pipe 10 away from the air pump 4 is connected to the four-in-one gas detector 3 through the flange 12, ensuring that the gas enters the interior of the four-in-one gas detector 3 stably and without leakage. After receiving the gas, the four-in-one gas detector 3 immediately detects and analyzes various carbon emission-related components in the gas, obtains key parameters such as gas concentration, and completes the data acquisition work.

[0026] After completing data acquisition, the four-in-one gas detector 3 transmits the detected gas concentration data in real time as an electrical signal to the PLC controller 2 fixedly connected to the outer wall of the main pipe 1. The PLC controller 2, as the control core of the module, immediately calculates the data and compares it with preset thresholds upon receiving the signal: when the detected gas concentration value is within the normal range, the PLC controller 2 maintains the current operating state of each component, i.e., the gas pump 4 maintains stable power operation, the three-way pneumatic ball valve 8 maintains the gas flow path to the discharge pipe 6, and the alarm light 5 remains off, ensuring normal module monitoring and gas emission; when a gas concentration value is detected... When the gas concentration exceeds the preset threshold, the PLC controller 2 immediately triggers intelligent control instructions, which are transmitted to the relevant components in the form of electrical signals through wires: on the one hand, it controls the three-way pneumatic ball valve 8 to adjust the valve state, close the discharge pipe 6 passage and connect the branch pipe 13 with the main pipe 1, thereby reducing the local gas concentration through the branch pipe 13 and avoiding safety risks caused by excessive concentration; on the other hand, it controls the alarm light 5 to light up, so as to remind the on-site staff or remote monitoring personnel to pay attention to the abnormal situation in a timely manner with a clear warning signal. At the same time, it can adjust the operating power of the air pump 4 according to actual needs to optimize the gas extraction rate and further assist in controlling the gas concentration.

[0027] The NB-IoT module built into the four-in-one gas detector 3 processes the key gas data detected according to a preset format after gas detection. Then, it transmits the data remotely to a designated monitoring platform or terminal device via the NB-IoT network. This remote transmission method eliminates the need for on-site personnel and is particularly suitable for hazardous environments such as industrial explosion-proof areas. It reduces on-site operational risks and allows personnel to obtain monitoring data in real time. At the same time, the remote monitoring platform can centrally manage and analyze the data transmitted from multiple modules, providing data support for carbon emission control and realizing full-cycle dynamic monitoring of carbon emission gases.

[0028] Throughout the entire operation, all components are sealed together via flange 12. The reinforced sleeve ensures the structural stability of the main pipe 1, improving the explosion-proof performance of the module from a hardware perspective. The coordinated control of the PLC controller 2 with each component and the remote data transmission of the NB-IoT module enable intelligent and information-based monitoring from a software perspective. Ultimately, a complete working loop of gas flow, data acquisition, intelligent decision-making, and remote feedback is formed, ensuring the module's efficient monitoring and control of carbon emission gases.
