[0005] Regarding the above-mentioned related technologies, when the data acquisition device is applied in the petroleum refining equipment, the sensor will directly contact the high-temperature gas and corrosive gas in the petroleum refining equipment, causing the sensor to be exposed to the high-temperature and corrosive gas, affecting the accuracy of the sensor measurement data. Utility Model Content

[0006] In order to improve the accuracy of sensor measurement data and reduce the influence of high temperature environment and corrosive environment on sensor measurement accuracy, the utility model provides a petroleum refining data acquisition device based on the Internet of Things.

[0007] The utility model provides a petroleum refining data acquisition device based on the Internet of Things, which adopts the following technical solutions:

[0008] An Internet of Things-based petroleum refining data acquisition device comprises a housing, a gas sensor disposed on the housing, and a control unit disposed on the housing, wherein the gas sensor and the control unit are electrically connected;

[0009] The shell is further provided with an isolation chamber, the isolation chamber is provided with a first ventilation hole, and the first ventilation hole is communicated with the outside of the shell;

[0010] The housing is further provided with a first rotating member, a first sealing member, and a first driving member. The first rotating member is provided corresponding to the first ventilation hole. The first sealing member is provided on the end surface of the first rotating member close to the first ventilation hole. The first driving member is fixedly installed on the housing and is in transmission connection with the first driving member.

[0011] The gas sensor is installed inside the isolation chamber, and the gas sensor and the first driving member are both connected to the control unit via electrical signals.

[0012] By adopting the above technical solution, when it is necessary to use a gas sensor to detect gas in the oil refining process, the first ventilation hole of the isolation chamber is connected to the space inside the oil refining equipment, and the control unit controls the first driving member to drive the first rotating member to rotate and open the first ventilation hole on the isolation chamber. At this time, the gas in the oil refining equipment flows into the isolation chamber, and the gas sensor contacts the gas in the oil refining equipment and performs detection and analysis; when the gas sensor completes the analysis of the gas in the isolation chamber, the control unit controls the first driving device to drive the first rotating member to rotate, and the first rotating member rotates to cover the first ventilation hole on the isolation chamber. The first sealing member on the first rotating member further seals the first ventilation hole. At this time, the interior of the isolation chamber and the oil refining equipment are isolated from each other, and the sensor no longer contacts the gas in the oil refining equipment. In this way, when gas detection is required, the isolation chamber is opened, the gas sensor detects the air inside the isolation chamber, and the isolation chamber is closed after the detection is completed, reducing the time the gas sensor is exposed to the high-pressure corrosive environment, reducing the impact of the high-temperature corrosive environment on the gas sensor, and thereby improving the measurement accuracy of the gas sensor.

[0013] Optionally, the isolation chamber is further provided with a second ventilation hole, the second ventilation hole is arranged opposite to the first ventilation hole, and the second ventilation hole is connected to the outside of the shell;

[0014] The housing is further provided with a second rotating member, which is arranged corresponding to the second ventilation hole. A second sealing member is provided on the end surface of the second rotating member close to the second ventilation hole. The second rotating member is transmission-connected to the first driving member.

[0015] By adopting the above technical solution, the control unit will control the first driving member to drive the first rotating member to rotate and open the first vent hole on the isolation chamber, and the second rotating member and the second sealing member will rotate synchronously with the first rotating member to close the second vent hole, so that the second vent hole is in a closed state. At this time, the gas in the petroleum refining equipment can only be exchanged through the first vent hole and the gas in the isolation chamber; when the control unit controls the first driving device to drive the first rotating member to rotate to close the first vent hole, the second rotating member and the second sealing member will rotate synchronously with the first rotating member to open the second vent hole. At this time, the inside of the isolation chamber and the petroleum refining equipment are isolated from each other, and the air outside the isolation chamber and the petroleum refining equipment is exchanged, so that the sensor is in an external clean environment. The second ventilation hole is set in this way to connect the external environment with the interior of the isolation chamber, and the second rotating part and the second sealing part are controlled to close the second ventilation hole when the first ventilation hole is opened, so that the isolation chamber and the internal ventilation of the petroleum refining equipment are connected. The gas sensor detects the gas inside the isolation chamber. When the first ventilation hole is closed, the second ventilation hole is opened to connect the isolation chamber with the external clean environment. This can naturally cool the gas sensor and reduce the continuous corrosion of the corrosive gas on the gas sensor inside the isolation chamber, further reducing the impact of the corrosive gas on the gas sensor and improving the measurement accuracy of the gas sensor.

[0016] Optionally, the first rotating member and the second rotating member are both installed inside the isolation chamber, the first rotating member and the second rotating member are connected through a transmission assembly, the transmission assembly is connected to the first driving member in a transmission manner, and the first rotating member, the second rotating member and the isolation chamber are coaxially arranged.

[0017] By adopting the above technical solution, the first rotating member and the second rotating member are fixedly installed inside the isolation chamber, so that the various components are arranged along the same axis, which not only reduces the lateral size of the equipment and makes the overall structure more compact, but also improves the accuracy of the synchronous rotation of the first rotating member and the second rotating member. At the same time, installing the first rotating member and the second rotating member inside the isolation chamber can also reduce the direct contact between the various components and the corrosive gas outside the isolation chamber, reduce the erosion of the corrosive gas on the various components, and extend the service life.

[0018] Optionally, the transmission assembly includes a transmission rod and a bevel gear, one end of the transmission rod is fixedly connected to the first rotating member, and the other end is fixedly connected to the second rotating member, the bevel gear is arranged on the transmission rod, and the bevel gear is connected to the gear transmission rod of the output shaft of the first driving member.

[0019] By adopting the above technical solution, when the first driving member rotates, the gear at the end of the output shaft of the first driving member drives the bevel gear to rotate, and the bevel gear is fixedly arranged with the transmission rod so that the transmission rod rotates synchronously with the bevel gear. Since the two ends of the transmission rod are respectively connected to the first rotating member and the second rotating member, the first rotating member and the second rotating member rotate synchronously with the transmission rod. By staggering the first rotating member and the second rotating member and correspondingly arranging the first ventilation hole and the second ventilation hole, the first ventilation hole and the second ventilation hole can be staggered and opened; or by correspondingly arranging the first rotating member and the second rotating member and staggering the first ventilation hole and the second ventilation hole, the first ventilation hole and the second ventilation hole can be staggered and opened. In this way, the transmission rod is directly connected to the first rotating member and the second rotating member, so that power can be accurately transmitted on the transmission rod, reducing energy loss caused by indirect transmission; and the accuracy of the synchronous rotation of the first rotating member and the second rotating member can be improved, reducing the misalignment or delay problem caused by different axes. Stable transmission reduces the possibility of mechanical failure and extends the service life of the equipment.

[0020] Optionally, the transmission assembly also includes a plurality of support members fixedly arranged inside the isolation chamber, the plurality of support members are arranged along the axial direction of the isolation chamber, a support ring is provided at the middle position of each support member, the support ring is coaxially arranged with the isolation chamber, and the support ring is sleeved on the transmission rod.

[0021] By adopting the above-mentioned technical solution, the support member and the support ring can support and limit the transmission rod, so that the position accuracy of the transmission rod can be improved during the rotation process, the vibration of the transmission rod during the transmission process can be reduced, and the wear of the gears on the transmission rod can be reduced. At the same time, the transmission rod can also drive the first rotating member and the second rotating member to rotate, so that the first rotating member and the second rotating member are in a relatively stable position, increasing the sealing degree of the first seal on the first rotating member to the first ventilation hole and the sealing degree of the second seal on the second rotating member to the second ventilation hole; multiple support members are arranged along the axial direction of the isolation chamber, and can also provide multi-point support for the transmission rod, thereby enhancing the stability of the overall structure.

[0022] Optionally, the transmission rod is further provided with a rotating bearing corresponding to the support member one by one, the outer ring of the rotating bearing is fixedly set on the support ring, and the inner ring sleeve of the rotating bearing is set on the transmission rod.

[0023] By adopting the above technical solution, the rotating bearing reduces the friction between the transmission rod and the support ring, because the rolling elements (such as balls or rollers) inside the bearing reduce the sliding friction of the direct contact surface. Reducing friction not only reduces energy loss, but also reduces wear between the transmission rod and the support ring, thereby extending the service life of the device. In addition to reducing the friction between the transmission rod and the support ring, the rotating bearing can also axially limit the transmission rod, reduce vibration and deviation during the rotation of the transmission rod, reduce wear of the bevel gear, and at the same time increase the airtightness of the first seal and the first ventilation hole, the second seal and the second ventilation hole.

[0024] Optionally, a filter device is provided at the second ventilation hole, the filter device is fixedly provided on the shell, and the filter device and the second ventilation hole are sealed.

[0025] By adopting the above technical solution, when the second ventilation hole exchanges gas with the external environment, the external air and the air inside the isolation chamber need to first pass through the filtering device when exchanging gas. When the corrosive gas inside the isolation chamber is discharged outward through the second ventilation hole, the filtering device can filter the corrosive gas inside the isolation chamber, reducing the corrosive gas inside the isolation chamber from being directly discharged into the external environment, causing pollution to the environment, and improving the safety of the device; when the external air enters the isolation chamber through the second ventilation hole, the filtering device can effectively remove dust, particulate matter and other potential pollutants in the air entering the isolation chamber, which helps to protect the internal components of the isolation chamber, and at the same time reduces the pollution of oil caused by pollutants entering the oil refining equipment.

[0026] Optionally, a circulation fan is fixedly installed inside the isolation chamber.

[0027] By adopting the above technical solution, the circulating fan can accelerate the air circulation in the isolation chamber, promote the air flow around the gas sensor, and help accelerate the exchange of air inside the isolation chamber with the air inside the oil refining equipment, and between the air inside the isolation chamber and the air in the external environment, so that the gas concentration detected by the gas sensor is more accurate and timely, and the accuracy of the detection data is improved; at the same time, the gas inside the isolation chamber can be quickly exchanged with the gas in the external environment, reducing the damage of high-temperature corrosive gases to various components inside the isolation chamber and extending the service life.

[0028] Optionally, an Internet of Things module is installed inside the shell, and the Internet of Things module is electrically connected to the control unit.

[0029] By adopting the above technical solution, multiple data acquisition devices can be installed at different locations in the oil refining equipment. These multiple data acquisition devices can communicate with each other through the Internet of Things module and send the collected data to a remote management platform. By setting up multiple data acquisition devices equipped with IoT sensors and sending the collected information to the remote management platform for unified analysis, the analyzed data can be made universal, avoiding the one-sided data collection results caused by different local gas conditions, and improving the accuracy of data collection and analysis. At the same time, by installing the Internet of Things module, real-time transmission can be made to a cloud server or remote control center, realizing remote monitoring of gas concentration.

[0030] In summary, the present invention has at least one of the following beneficial technical effects:

[0031] An isolation chamber is set up and a first ventilation hole is set up on the isolation chamber, and a first rotating part is set up in cooperation with the first ventilation hole to close the first ventilation hole. The gas sensor is installed inside the isolation chamber. When the gas sensor is needed for detection, the first rotating part opens the first ventilation hole, and the gas enters the isolation chamber through the first ventilation hole, so that the gas sensor can detect the gas entering the isolation chamber; when the gas sensor is not needed to detect the gas, the first rotating part closes the first ventilation hole. In this way, the contact time of the gas sensor with high-temperature gas or corrosive gas can be reduced, the impact of the high-temperature corrosive environment on the gas sensor can be reduced, and the measurement accuracy and service life of the sensor can be improved.

[0032] A second ventilation hole and a second rotating part for closing the second ventilation hole are provided on the isolation chamber, so that the air inside the isolation chamber can be exchanged with the air in the external environment. This can not only naturally cool down the gas sensor after the detection is completed, but also reduce the continuous corrosion of the gas sensor by the corrosive gas inside the isolation chamber, further reduce the impact of the corrosive gas on the gas sensor, and improve the measurement accuracy of the gas sensor.

[0033] A transmission assembly and a support member are provided so that the first rotating member and the second rotating member can rotate coaxially, so that power can be accurately transmitted on the transmission assembly, reducing energy loss. At the same time, the accuracy of the synchronous rotation of the first rotating member and the second rotating member is improved, the misalignment or delay problems caused by different axes are reduced, the possibility of mechanical failure is reduced, and the service life of the equipment is extended.

[0034] A filtering device is set at the position of the second ventilation hole. When gas exchange is carried out, it can not only reduce the pollution to the environment caused by the corrosive gas inside the isolation chamber being directly discharged into the external environment; it can also remove dust pollutants in the air entering the isolation chamber, reducing the pollution to the oil caused by pollutants entering the oil refining equipment.

[0035] By installing an IoT module in a data acquisition device, multiple data acquisition devices can communicate with each other and work together to simultaneously monitor gases at different locations, thereby improving the accuracy of data acquisition. The IoT module also facilitates remote control and information transmission of the data acquisition device, facilitating distributed installation in petroleum refining equipment.
