[0002] In steel enterprises, sealed gas holders are commonly used to store coal gas. These oil-sealed gas holders typically consist of a cabinet containing the coal gas. A piston is installed inside the cabinet, and by adding a counterweight to the piston, the pressure of the stored coal gas inside the cabinet is maintained at the specified level. An oil groove is located at the bottom of the cabinet, containing sealing oil. This sealing oil is primarily used for sealing, lubricating, and cooling the piston against the cabinet's side walls.

[0003] In related technologies, observation windows are installed on the side wall of the gas holder, opposite the bottom oil groove. These windows allow for observation of the sealing fluid level, quality, and any related malfunctions within the holder. However, this method relies on manual observation. Firstly, manual observation cannot achieve real-time monitoring; instances of excessively high or low fluid levels during monitoring intervals can easily cause gas holder malfunctions. Secondly, manual observation has limited accuracy, making it prone to errors in judging fluid level and sealing fluid quality. Summary of the Invention

[0005] This application aims to address the problems of limited real-time level detection and accuracy in existing technologies that rely on observation windows to monitor the level of sealing fluid inside gas holders. By installing a detection device connected to the gas storage tank, the sealing fluid flows into the device, and its level is detected. This allows for real-time monitoring of the sealing fluid level without requiring additional space within the gas storage tank. Furthermore, the use of a detection device eliminates the possibility of errors from manual observation, thus improving the accuracy of sealing fluid level detection.

[0010] In some embodiments, the detection device further includes an early warning unit that performs early warning operations based on oil level information and / or water level information, including: If the difference between the oil level information and the preset oil level information is greater than the first threshold, the control warning unit will issue the first warning information. If the difference between the water level information and the preset water level information is greater than the second threshold, the control and early warning unit will issue a second early warning message.

[0011] In some embodiments, the detection device further includes a temperature sensing element and a heating element, and the method for detecting the sealing fluid further includes: Obtain the ambient temperature detected by the temperature sensor; If the ambient temperature is less than or equal to the preset temperature, the heating element will be controlled to heat the water at the bottom of the sealing oil.

[0012] In some embodiments, the detection device further includes a communication unit, and the method for detecting the sealing fluid further includes: The control communication unit sends oil level information and / or water level information to electronic devices associated with the detection device.

[0013] Secondly, this application proposes a gas storage cabinet, comprising: The cabinet includes a liquid storage space for storing sealing fluid, which includes sealing oil and water. The side wall of the cabinet has through holes. The detection device is installed in the cabinet and connected to the cabinet through a through hole.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0021] Please see Figure 1 This is a schematic flowchart of a method for detecting a sealing liquid provided in an embodiment of this application. The method for detecting a sealing liquid is used in a gas storage cabinet, wherein the gas storage cabinet includes a cabinet body and a detection device. The cabinet body stores a sealing liquid, and the cabinet body has a through hole. The detection device is connected to the cabinet body through the through hole. The sealing liquid includes sealing oil and water.

[0022] Specifically, the sealing fluid detection method provided in this application can be used to detect the level of sealing fluid stored inside a gas storage cabinet, that is, to detect the storage volume of sealing oil and water. It should be noted that the gas storage cabinet can be used to store gas; exemplarily, the gas storage cabinet can be a thin oil-sealed gas holder. The gas storage cabinet can consist of a cabinet body composed of a base plate, uprights, side panels, a top plate, and a conduit. A piston that can move up and down is installed inside the cabinet. Gas enters the cabinet from the bottom and is stored in the space enclosed by the base plate, piston, and side panels. By adding a counterweight to the piston, the pressure of the gas stored inside the cabinet is made to meet specified requirements. When the pressure in the inlet pipe of the cabinet is higher than the pressure inside the cabinet, gas enters the gas holder, pushing the piston upward. When the pressure in the inlet pipe is lower than the pressure inside the cabinet, the gas inside the cabinet is expelled, and the piston begins to descend.

[0023] In addition, an oil groove is usually provided at the bottom of the cabinet. The oil groove is used to store the sealing fluid, and the sealing fluid is driven by a pump or other driving device, allowing it to circulate within the pipes inside the cabinet. This ensures that the sealing fluid is delivered between the piston and the side wall of the cabinet. Specifically, the oil pump drives the sealing fluid at the bottom of the cabinet, causing it to enter the oil tank at the top of the cabinet. Then, the sealing fluid flows under gravity along the side wall of the cabinet to the space between the piston and the side wall, and finally flows back to the oil groove at the bottom of the cabinet, thus completing the circulation process of the sealing fluid.

[0024] The sealing fluid effectively seals the space between the piston and the cabinet's side wall. Specifically, the sealing fluid forms an oil film between the piston and the cabinet's side wall, preventing gas leakage from gaps. The sealing fluid also maintains the internal pressure of the cabinet, stabilizing it through the oil film and preventing external air from entering or gas from escaping. The oil film also acts as a buffer, reducing the impact between the piston and the cabinet's side wall.

[0025] The sealing fluid also serves as a lubricant, lubricating the contact surface between the piston and the side wall of the cabinet, reducing friction and wear, extending equipment life, ensuring smooth operation, making piston movement more stable, and preventing jamming or vibration.

[0026] The sealing fluid also plays a cooling role. Through the sealing fluid, the piston absorbs and carries away the heat generated by the friction between the piston and the cabinet wall during the piston movement, preventing local overheating and thus achieving a stable operating temperature. In addition, the sealing fluid can achieve cooling during circulation, thereby helping to maintain the stability of the internal temperature of the gas holder.

[0027] In addition, the sealing fluid can absorb impurities inside the cabinet, thus cleaning it. It also protects the metal surfaces of the piston and cabinet, preventing corrosion.

[0028] Specific methods for testing sealing fluid may include: S110. After the sealing fluid in the cabinet enters the detection device, the liquid level information of the sealing fluid in the detection device is detected.

[0029] Specifically, after the sealing fluid in the cabinet enters the detection device, the liquid level information of the sealing fluid in the detection device can be detected. The detection device can be installed on the cabinet, located on the outside of the cabinet. Simultaneously, a through-hole can be opened in the cabinet, through which the detection device connects to the interior of the cabinet. It should be noted that because the detection device is connected to the interior of the cabinet, the sealing fluid inside the cabinet can enter the detection device. In this way, the detection device can detect the liquid level information inside itself.

[0030] Specifically, the detection device is connected to the interior of the cabinet through a through-hole. It should be noted that this connection allows the sealing fluid inside the cabinet to enter the detection device. By detecting the level of the sealing fluid inside the device, the oil level of the sealing fluid inside the cabinet can be determined.

[0031] For example, the through-hole on the cabinet can be directly opened at the level of the sealing fluid at the bottom of the cabinet. This way, when the detection device is connected to the cabinet through the through-hole, the sealing fluid can flow directly into the detection device. At this time, the level of the sealing fluid in the detection device is the same as the level of the sealing fluid in the cabinet. After the detection device detects the level of the sealing fluid inside itself, it also obtains the level of the sealing fluid in the cabinet. In other words, at this point, the oil level information of the sealing fluid inside the cabinet is the same as the liquid level information in the detection device.

[0032] S120, Detect the water level information at the bottom of the sealing oil.

[0033] Specifically, water is stored at the bottom of the sealing oil, and the water level can be monitored using a detection device. It should be noted that the sealing fluid may also contain water, which can be used to assist in sealing, regulate the temperature of the sealing oil, and flush away impurities inside the cabinet. However, in actual operation, the amount of water stored should not be too large to avoid affecting the sealing and lubrication effects of the sealing oil. Therefore, monitoring the water level allows for real-time monitoring of the water level at the bottom of the sealing oil, preventing excessive water accumulation from affecting the operation of the gas storage cabinet.

[0034] S130. Determine the oil level information of the sealing oil based on the liquid level information and water level information.

[0035] Specifically, after obtaining the overall liquid level information of the sealing fluid and the water level information at the bottom of the sealing oil, the oil level information of the sealing oil can be obtained based on the liquid level information and the water level information. It can be understood that by subtracting the water level information from the overall liquid level information of the sealing fluid, the oil level information of the sealing oil can be obtained, and then the storage quantity of the sealing oil can be determined based on the oil level information.

[0036] S140. Conduct early warning operations based on oil level information and / or water level information.

[0037] Specifically, after determining the oil and water levels of the sealing fluid in the cabinet, the detection device can also issue warnings based on these levels. Understandably, if the amount of sealing oil at the bottom of the cabinet is too high or too low, it will affect the actual operation of the gas storage cabinet. That is, if the oil level is too high or too low, the normal operation of the gas storage cabinet cannot be guaranteed. In this case, a warning operation is needed to notify relevant personnel to replenish the sealing oil or drain the excess sealing oil in time to prevent malfunction. Similarly, if the amount of water in the cabinet is too high or too low, a warning operation can also be issued to notify relevant personnel to replenish or drain the water in time to ensure the normal operation of the gas storage cabinet.

[0038] In summary, the sealing fluid detection method proposed in this application connects the detection device to the cabinet of the gas storage tank. After the sealing fluid enters the detection device inside the cabinet, the device can detect the liquid level information of the sealing fluid inside itself and the water level information of the water at the bottom of the sealing oil. Based on the liquid level information and water level information, the oil level information of the sealing oil inside the cabinet can be determined, realizing real-time detection of the storage amount of sealing oil and water inside the cabinet. It does not require manual observation, avoids the existence of detection gaps, and avoids the leakage of sealing fluid during the detection gap process, which could damage the gas storage tank. It also avoids the errors that may occur in manual judgment, thus improving the accuracy of the detection of the storage amount of sealing oil and water.

[0039] In some instances, the detection device includes a first detection element and a second detection element, which detect the liquid level information of the sealing fluid in the detection device, including; Obtain the first detection signal of the first detection component; The liquid level information is determined based on the first detection signal; The water level at the bottom of the sealing oil is detected, including: Acquire the second detection signal of the second detection component; The water level at the bottom of the sealing oil is determined based on the second detection signal.

[0040] In this embodiment, the detection device can specifically detect the liquid level information of the sealing fluid and the water level information inside itself through the first detection element and the second detection element.

[0041] Specifically, after the sealing liquid and water enter the detection device in the cabinet, the first detection signal of the first detection element can be obtained, and then the liquid level information of the sealing liquid in the detection device can be determined based on the first detection signal.

[0042] For example, the first detection element can be a magnetostrictive level gauge. A float is attached to the outside of the sensor rod of the magnetostrictive level gauge, and this float can move up and down along the rod as the liquid level changes. Specifically, different models of magnetostrictive level gauges can be selected according to the density of the sealing oil so that the float can be suspended on the surface of the sealing oil. Inside the float is a set of permanent magnetic rings. When the magnetic field of the pulse current meets the magnetic field of the magnetic rings generated by the float, the magnetic field around the float changes, causing the waveguide wire made of magnetostrictive material to generate a torsional wave pulse at the location of the float, which is the first detection signal. The first detection signal is transmitted back along the waveguide wire at a fixed speed, and the detection mechanism determines the liquid level information of the sealing fluid based on the first detection signal.

[0043] Accordingly, for the detection of water level information, a second detection signal of the second detection element can be obtained, and then the water level information of the water at the bottom of the sealing oil can be determined based on the second detection signal.

[0044] For example, the second detection element can also be a magnetostrictive level gauge. A suitable model of magnetostrictive level gauge can be selected based on the density of the water, allowing the float to suspend on the water surface, specifically at the interface between the water and the sealing oil. When the pulsed current magnetic field encounters the magnetic field of the magnetic ring generated by the float, the magnetic field around the float changes, causing the waveguide wire made of magnetostrictive material to generate a torsional wave pulse at the location of the float—that is, the second detection signal. This second detection signal travels back along the waveguide wire at a fixed speed, and the detection mechanism determines the water level information based on the second detection signal.

[0045] In summary, by setting up a first and a second detection element, the liquid level information of the sealing fluid and the water level information within the detection device can be automatically detected. This eliminates the need for manual observation, avoids detection gaps, and prevents sealing fluid leakage during the detection process that could damage the gas storage cabinet. It also avoids errors that may occur with manual judgment, thus improving the accuracy of sealing fluid level detection.

[0046] In some instances, the detection device also includes an observation window to detect the level of the sealing fluid within the detection device, including: The initial liquid level information of the sealing fluid in the detection device and the liquid level image in the observation window are collected. The initial liquid level information is corrected based on the liquid level image to obtain the liquid level information.

[0047] In this embodiment, the detection device may also be provided with an observation window, through which the height of the sealing liquid inside the detection device can be directly observed, thereby cooperating with the first detection element to detect the liquid level information of the sealing liquid, so as to further improve the detection accuracy of the liquid level information.

[0048] Specifically, when detecting the level information of the sealing fluid, firstly, the initial level information of the sealing fluid and the level image through the observation window can be acquired. Then, the initial level information is corrected based on the level image to obtain the level information of the sealing fluid.

[0049] In summary, the detection of liquid level information does not rely entirely on the detection results of the initial liquid level of the sealing liquid directly by the detection device. It can also combine the liquid level image to correct the initial liquid level information, thereby obtaining the liquid level information and improving the accuracy of liquid level information detection.

[0050] In addition, by setting an observation window on the detection device, staff can easily observe the internal sealing fluid, make it easier for them to judge the quality of the sealing fluid, and further facilitate the management of the gas storage cabinet.

[0051] In some instances, the detection device also includes an early warning unit that performs early warning operations based on oil level information and / or water level information, including: If the difference between the oil level information and the preset oil level information is greater than the first threshold, the control warning unit will issue the first warning information. If the difference between the water level information and the preset water level information is greater than the second threshold, the control and early warning unit will issue a second early warning message.

[0052] In this embodiment, different warning messages can be used to monitor the oil level of the sealing oil and the water level of the water inside the cabinet. This makes it easier for staff to judge the storage volume of the sealing oil and water, and further facilitates the management of the gas storage cabinet.

[0053] Specifically, the detection device may include an early warning unit that can issue different operational information when the storage levels of sealing oil and water are abnormal.

[0054] For example, if the difference between the sealing oil level information and the preset oil level information is greater than a first threshold, it indicates that the amount of sealing oil stored in the cabinet is too much or too little, which may affect the operation of the gas storage cabinet. In this case, the warning unit can be controlled to issue a first warning message. When the operator receives the first warning message, they can determine that the amount of sealing oil stored in the cabinet is abnormal and take timely action. Similarly, if the difference between the water level information and the preset water level information is greater than a second threshold, it indicates that the amount of water stored in the cabinet is too much or too little. In this case, the warning unit can be controlled to issue a second warning message. When the operator receives the second warning message, they can determine that the amount of water stored in the cabinet is abnormal and take timely action.

[0055] In summary, by issuing first and second warning messages through the early warning unit, it is possible to distinguish between abnormal storage levels of sealing oil and water, facilitating timely handling by staff and improving the management efficiency of gas storage cabinets.

[0056] In some instances, the detection device also includes a temperature sensing element and a heating element, and the method for detecting the sealing fluid also includes: Obtain the ambient temperature detected by the temperature sensor; If the ambient temperature is less than or equal to the preset temperature, the heating element will be controlled to heat the water at the bottom of the sealing oil.

[0057] In this embodiment, the detection device may further include a temperature detection element, which can be used to detect the ambient temperature of the environment in which the gas storage cabinet is located. It is understood that since water is stored at the bottom of the gas storage cabinet, when the ambient temperature is low, such as below 0 degrees Celsius, the water at the bottom of the cabinet will freeze. This will not only affect the circulation of the sealing oil and water at the bottom of the cabinet, but also affect the auxiliary sealing and lubrication effects of the water.

[0058] Accordingly, the detection device also includes a heating element. When the temperature detection element detects that the ambient temperature is too low, the heating element can also heat the water at the bottom of the sealing oil to prevent the water from freezing. This prevents the water from freezing and affecting the circulation of the sealing oil and water at the bottom of the cabinet, and also avoids affecting the auxiliary sealing body and lubrication effect of the water.

[0059] Specifically, during the operation of the gas storage cabinet, a temperature sensor can be used to monitor the ambient temperature output by the gas storage cabinet. If the ambient temperature detected by the temperature sensor is less than or equal to a preset temperature, the heating element can be activated to heat the water at the bottom of the sealing oil, preventing the water from freezing. The preset temperature can be set to 0 degrees Celsius.

[0060] In summary, by setting up temperature detection and heating elements, the temperature detection element is used to monitor the ambient temperature of the gas storage cabinet. When the ambient temperature is less than or equal to the preset temperature, the heating element is used to heat the water at the bottom of the sealing oil to prevent the water from freezing. This prevents the frozen water from affecting the circulation of the sealing oil and water at the bottom of the cabinet, and also avoids affecting the auxiliary sealing and lubrication effects of the water.

[0061] In some instances, the detection device also includes a communication unit, and the method for detecting sealing fluid also includes: The control communication unit sends oil level information and / or water level information to electronic devices associated with the detection device.

[0062] In this embodiment, the detection device may also be equipped with a communication unit. Through the communication unit, the oil level information and water level information of the sealing oil in the cabinet can be sent to the electronic device associated with the detection device, so that the staff holding the electronic device can know the storage amount of sealing oil and water in the cabinet in a timely manner, thereby further facilitating the staff to manage the operation of the gas storage cabinet.

[0063] Please see Figure 2 The above is a structural block diagram of a gas storage cabinet provided in an embodiment of this application. The gas storage cabinet 200 includes: Cabinet 202 includes a liquid storage space for storing sealing fluid, which includes sealing oil and water. The side wall of cabinet 202 has a through hole 204. The detection device 206 is installed in the cabinet 202 and is connected to the cabinet 202 through the through hole 204. The sealing liquid enters the detection device 206 through the through hole 204. The control device 208 is electrically connected to the detection device 206 and is used to perform the sealing liquid detection method as described in any of the above embodiments.

[0064] The gas storage cabinet 200 provided in this application includes a cabinet body 202, which includes a liquid storage space, suitable for storing sealing liquid. Exemplarily, the cabinet body 202 can be composed of a bottom plate, uprights, side panels, a top plate, and a conduit. A piston capable of vertical movement is installed inside the cabinet body 202. Gas enters the cabinet body 202 from the bottom and is stored within the space enclosed by the bottom plate, piston, and side panels. The liquid storage space is located at the bottom. A driving device such as an oil pump drives the sealing liquid, allowing it to circulate within pipes inside the cabinet body 202, thereby delivering the sealing liquid between the piston and the side walls of the cabinet body 202. Specifically, the sealing fluid at the bottom of the cabinet 202 is driven by an oil pump, so that the sealing fluid enters the oil tank at the top of the cabinet 202 through the oil pump. Then, the sealing fluid flows along the side wall of the cabinet 202 by gravity to the space between the piston and the side wall of the cabinet 202, and then flows back to the oil groove at the bottom of the cabinet 202, thus realizing the circulation process of the sealing fluid.

[0065] Furthermore, the gas storage cabinet 200 may also include a detection device 206, which can be mounted on the cabinet body 202 and located outside the cabinet body 202. Simultaneously, a through hole 204 can be provided on the cabinet body 202, through which the detection device 206 communicates with the interior of the cabinet body 202. It should be noted that because the detection device 206 is connected to the interior of the cabinet body 202, the sealing fluid inside the cabinet body 202 can enter the detection device 206. In this way, the detection device 206 can detect the level of the sealing fluid inside itself, and thus determine the level of the sealing fluid inside the cabinet body 202 based on the level of the sealing fluid inside itself.

[0066] For example, the through hole 204 on the cabinet 202 can be directly opened at the level of the sealing fluid at the bottom of the cabinet 202. Thus, when the detection device 206 is connected to the cabinet 202 through the through hole 204, the sealing fluid can flow directly into the detection device 206 through the through hole 204. At this time, the level of the sealing fluid in the detection device 206 is equal to the level of the sealing fluid in the cabinet 202. After the detection device 206 detects the level of the sealing fluid inside itself, it also obtains the level of the sealing fluid in the cabinet 202.

[0067] It should be noted that the through hole 204 on the cabinet 202 can be a through hole 204 opened in the original observation window of the cabinet 202. That is, the detection device 206 can be installed using the through hole 204 of the original observation window on the gas storage cabinet 202 to achieve communication between the detection device 206 and the cabinet 202. Specifically, the main body of the detection device 206 can be opened according to the size of the through hole 204 of the original observation window of the cabinet 202, and then connected to the cabinet 202 through components such as flanges and sealing rings to achieve communication between the main body and the cabinet 202, so that the sealing fluid of the cabinet 202 can enter the main body to detect the oil level and water level information of the sealing oil. In addition, a valve can also be installed in the through hole 204, and the opening and closing of the valve can achieve communication between the inside of the cabinet 202 and the outside.

[0068] Furthermore, the gas storage cabinet 200 also includes a control device 208, which is electrically connected to the detection device 206, thereby enabling the execution of the sealing liquid detection method as described in any of the above embodiments.

[0069] In summary, the gas storage cabinet 200 provided in this application includes a cabinet body 202 and a detection device 206. The detection device 206 is connected to the cabinet body 202 so that the sealing liquid in the liquid storage space of the cabinet body 202 can enter the detection device 206. The control device 208 is electrically connected to the detection device 206 and can perform the sealing liquid detection method as described in any of the above embodiments. Therefore, the gas storage cabinet 200 has all the beneficial effects of the above-described sealing liquid detection method, which will not be elaborated further here.

[0070] In some instances, the detection device 206 includes: The main body 210 is set in the cabinet 202 and is connected to the cabinet 202 through the through hole 204. The sealing liquid enters the main body 210 through the through hole 204. The first detection element 212 is disposed on the main body 210 and is used to detect the liquid level information of the sealing fluid inside the main body 210; The second detection element 214 is disposed on the main body 210 and is used to detect the water level information at the bottom of the sealing oil when water is stored at the bottom of the sealing fluid.

[0071] In this embodiment, please refer to Figure 3This is one of the structural schematic diagrams of the detection device in the gas storage cabinet provided in the embodiments of this application. The cabinet 202 may include a main body 210 and a first detection element 212 and a second detection element 214 disposed on the main body 210. The main body 210 is disposed in the cabinet 202 and is connected to the cabinet 202 through a through hole 204 on the cabinet 202. Specifically, it can be connected to the liquid storage space of the cabinet 202 so that the sealing liquid in the liquid storage space can enter the main body 210.

[0072] Furthermore, the first detection element 212 can be disposed on the main body 210, and at least a portion of the first detection element 212 can extend into the interior of the main body 210 to detect the liquid level information of the sealing fluid inside the main body 210. Correspondingly, the second detection element 214 can also be disposed on the main body 210, and at least a portion of the second detection element 214 can extend into the interior of the main body 210 to detect the water level information at the bottom of the sealing oil.

[0073] For example, both the first detection element 212 and the second detection element 214 can be magnetostrictive level gauges. A float is attached to the outside of the sensor rod of the magnetostrictive level gauge, and this float can move up and down along the rod as the liquid level changes. Specifically, the float can be selected according to the density of the sealing oil and the water. That is, the float of the first detection element 212 can float on the surface of the sealing oil, and the float of the second detection element 214 can float on the surface of the water, that is, at the interface between the sealing oil and the water. There is a set of permanent magnetic rings inside the float. When the magnetic field of the pulse current meets the magnetic field of the magnetic rings generated by the float, the magnetic field around the float changes, thereby causing the waveguide wire made of magnetostrictive material to generate a torsional wave pulse at the location of the float. This torsional pulse wave travels back along the waveguide wire at a fixed speed, and the detection mechanism determines the liquid level information of the sealing liquid and the water level information of the water based on the torsional pulse wave.

[0074] In some instances, the main body 210 has an observation port, and the detection device 206 also includes an observation window 216, which is sealed to the main body 210 and covers the observation port.

[0075] In this embodiment, please refer to Figure 4 The second schematic diagram of the detection device in the gas storage cabinet provided in this application embodiment shows that the detection device 206 can also be provided with an observation window 216. Through the observation window 216, the height of the sealing oil and water inside the detection device 206 can be directly observed, thereby cooperating with the first detection element 212 to detect the liquid level information of the sealing liquid, so as to further improve the detection accuracy of the liquid level information.

[0076] Specifically, when detecting the level information of the sealing fluid, firstly, the initial level information of the sealing fluid and the level image of the observation window 216 can be acquired. Then, the initial level information is corrected based on the level image to obtain the level information of the sealing fluid.

[0077] In summary, the detection of liquid level information does not rely entirely on the detection results of the initial liquid level of the sealing liquid directly by the detection device 206. It can also combine the liquid level image to correct the initial liquid level information, thereby obtaining the liquid level information and improving the accuracy of liquid level information detection.

[0078] In addition, by setting an observation window 216 on the detection device 206, it is convenient for staff to observe the internal sealing liquid, make it easier for staff to judge the quality of the sealing liquid, and further facilitate the management of the gas storage cabinet 200.

[0079] In some instances, the detection device 206 also includes: Temperature detection element 218 is disposed on the main body 210 and is used to detect the ambient temperature around the main body 210; Heating element 220, disposed on body 210, is used to heat the water at the bottom of the sealing oil when water is stored at the bottom of the sealing fluid and the ambient temperature around body 210 is less than or equal to a preset temperature.

[0080] In this embodiment, such as Figure 2 As shown, the detection device 206 may also include a temperature detection element 218, which can detect the ambient temperature of the environment in which the gas storage cabinet 200 is located. It is understood that since water is stored at the bottom of the gas storage cabinet 200, when the ambient temperature is low, such as below 0 degrees Celsius, the water at the bottom of the cabinet 202 will freeze. This will not only affect the circulation of sealing oil and water at the bottom of the cabinet 202, but also affect the auxiliary sealing and lubrication effects of the water.

[0081] Accordingly, the detection device 206 also includes a heating element 220. When the temperature detection element 218 detects that the ambient temperature is too low, the heating element 220 can also heat the water at the bottom of the sealing oil to prevent the water from freezing. This prevents the water from freezing and affecting the circulation of the sealing oil and water at the bottom of the cabinet 202, and also avoids affecting the auxiliary sealing body and lubrication effect of the water.

[0082] Specifically, during the operation of the gas storage cabinet 200, the temperature detection element 218 can be controlled to detect the ambient temperature output by the gas storage cabinet 200. If the ambient temperature detected by the temperature detection element 218 is less than or equal to the preset temperature, the heating element 220 can be controlled to operate, so as to heat the water at the bottom of the sealing oil and prevent the water from freezing. The preset temperature can be set to 0 degrees Celsius.

[0083] In summary, by setting up a temperature detection element 218 and a heating element 220, the temperature detection element 218 is controlled to detect the ambient temperature of the gas storage cabinet 200. When the ambient temperature is less than or equal to the preset temperature, the heating element 220 is controlled to heat the water at the bottom of the sealing oil to prevent the water from freezing. This prevents the water from freezing and affecting the circulation of sealing oil and water at the bottom of the cabinet 202, and also avoids affecting the auxiliary sealing body and lubrication effect of the water.

[0084] Furthermore, such as Figure 2 As shown, the gas storage cabinet 200 can also be equipped with a communication unit 222. Through the communication unit 222, the oil level information and water level information of the sealing oil in the cabinet 202 can be sent to the electronic equipment associated with the detection device 206, so that the staff holding the electronic equipment can know the storage amount of sealing oil and water in the cabinet 202 in a timely manner, thereby further facilitating the staff to manage the operation of the gas storage cabinet 200.
