Description

Technical Field

[0001] The utility model relates to the technical field of oil level gauges, in particular to an oil level gauge capable of remote monitoring. Background Art

[0002] As a key equipment in steel production, the efficient and stable operation of the steelmaking converter is crucial to the smooth operation of the entire steel production line. Among the many components of the converter, the reducer in the tilting area plays an extremely important role. It not only directly affects the tilting operation of the converter, but also is related to the safety and efficiency of the entire steelmaking process. Among them, the main function of the tilting reducer is to achieve precise control and smooth movement of the converter through the driving force of the motor when the converter is tapping steel and slag. In this process, the reducer converts the high-speed rotation of the motor into the low-speed and high-torque output required by the converter through its internal gear transmission system. This conversion not only ensures the accuracy of the converter's movement, but also ensures safety during operation.

[0003] However, in order to ensure the long-term stable operation of the tilting reducer, daily maintenance work is particularly important. Monitoring the oil level inside the reducer is a key link in maintenance work. Therefore, regularly checking the oil level inside the reducer and replenishing the lubricating oil in time are of great significance for extending the service life of the reducer and ensuring the normal operation of the converter. In the prior art, there are certain difficulties in monitoring the oil level of the tilting reducer. Since the local oil level gauge is installed on the outside of the reducer casing and is affected by the mechanical protection of the transmission area, the clarity and accuracy of observing the oil level are limited. The unclear oil level display and the long observation distance make it difficult for staff to accurately judge the actual oil level inside the reducer. This not only increases the difficulty of maintenance work, but also increases the risk of equipment failure due to inaccurate oil level monitoring. Therefore, a remotely monitored oil level gauge is needed. Utility Model Content

[0004] The embodiment of the utility model provides an oil level gauge that can be remotely monitored, which at least partially solves the technical problems in the prior art that the liquid level display is relatively vague and the actual internal oil level cannot be accurately judged due to the long observation distance due to the installation of mechanical protection in the transmission area, thereby realizing remote and accurate monitoring of the oil level gauge.

[0005] In the first aspect, in order to solve the above technical problems, the embodiments of the present utility model provide the following technical solutions:

[0006] An oil level gauge capable of remote monitoring comprises:

[0007] A main body container, the main body container is connected to the device under test through a pipeline;

[0008] A magnetic float, the magnetic float is arranged in the main container, and the height of the magnetic float changes synchronously with the liquid in the main container;

[0009] A magnetic induction device, which is disposed on the outer wall of the main container and detects the position of the magnetic float by magnetic induction;

[0010] A programmable logic controller, wherein the signal input end of the programmable logic controller is connected to the signal output end of the magnetic induction device to receive the oil level information from the magnetic induction device; the signal output end of the programmable logic controller is connected to the signal input end of the host computer to send the oil level information to the host computer for display.

[0018] Optionally, a drain port is provided at the lower end of the main container, and the drain port is sealed by a lower cover.

[0019] Optionally, the main container is cylindrical.

[0020] One or more technical solutions provided in the embodiments of the present utility model have at least the following technical effects or advantages:

[0021] The main container and the equipment under test achieve oil level synchronization through the principle of communicating vessels to ensure that the oil levels of the two are consistent. The magnetic float moves with the oil level change, and this action triggers the magnetic induction device to convert the real-time oil level information into electrical signals. These electrical signals are then sent to the programmable logic controller for processing. Through this system, the programmable logic controller can remotely transmit the liquid level data of the oil level gauge to the host computer, allowing maintenance personnel and inspection personnel to easily monitor the lubrication status of important equipment. It not only reduces the daily workload of maintenance personnel, but also improves the automation level of the equipment. More importantly, once the oil level of the equipment drops abnormally, the system can detect it in time, thereby preventing equipment accidents caused by lubrication failure, and further enhancing the safety of equipment operation.

In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0033] The embodiment of the utility model provides an oil level gauge that can be remotely monitored, which at least partially solves the technical problems in the prior art that the liquid level display is relatively vague and the actual internal oil level cannot be accurately judged due to the long observation distance due to the installation of mechanical protection in the transmission area, thereby realizing remote and accurate monitoring of the oil level gauge.

[0034] In the embodiment of the present utility model, there is provided Figure 1 and Figure 2 A remotely monitorable oil level gauge is shown, comprising:

[0035] The main body container 1 is connected to the device under test through the pipeline 3. The main body container 1 is the basic component of the entire oil level gauge. It is connected to the device under test (reducer) through the pipeline 3. The oil level of the main body container 1 and the oil level of the device under test are synchronized by using the communicating vessel principle, thereby realizing real-time monitoring of the oil level. In addition, the main body container 1 is made of corrosion-resistant and high-temperature resistant materials to ensure stable operation in various environments.

[0036] The magnetic float 5 is arranged in the main container 1, and the height of the magnetic float 5 changes synchronously with the liquid in the main container 1. The magnetic float 5 is the core component of the liquid level gauge, and it rises and falls with the change of the liquid level in the main container 1. Since the magnetic float 5 has a built-in magnet, it can interact with the external magnetic induction device 8, thereby realizing non-contact detection of the oil level.

[0037] The magnetic induction device 8 is arranged on the outer wall of the main container 1, and uses magnetic induction to detect the position of the magnetic float 5, so as to obtain the oil level information. Among them, the magnetic induction device 8 has the characteristics of high sensitivity and fast response speed, and can monitor the change of the oil level in real time. At the same time, since it adopts a non-contact detection method, it will not cause pollution or interference to the oil.

[0038] Programmable logic controller 11, the signal input end of the programmable logic controller 11 is connected to the signal output end of the magnetic induction device 8 to receive the oil level information from the magnetic induction device 8; the signal output end of the programmable logic controller 11 is connected to the signal input end of the host computer 12 to send the oil level information to the host computer 12 for display.

[0039] Among them, the programmable logic controller 11 (PLC) is the control center of the oil level gauge. Its signal input end is connected to the signal output end of the magnetic induction device 8, and receives the oil level information from the magnetic induction device 8. The PLC processes and analyzes this information through an internal preset program, and then sends the processed results to the host computer 12. The PLC has powerful data processing capabilities and stable working performance, which can ensure the accuracy and real-time performance of the oil level information. The host computer 12 is the remote monitoring terminal of the oil level gauge. Its signal input end is connected to the signal output end of the PLC, receives the oil level information from the PLC, and displays it on the interface of the host computer 12, such as Figure 3 As shown. Through the host computer 12, the user can view the changes in the oil level in real time and perform corresponding operations and adjustments as needed. The host computer 12 is usually equipped with a user interface and powerful data processing functions, making remote monitoring more convenient and efficient.

[0040] Furthermore, an oil level gauge window 9 is provided on the main container 1 .

[0041] Among them, the setting of the oil level gauge window 9 allows the operator to directly observe the oil level in the container without relying on other equipment or data interpretation. This intuitive display method makes oil level detection simple and clear, and reduces misjudgment caused by interpretation errors or equipment failures. At the same time, through the oil level gauge window 9, the operator can grasp the changes in the oil level in real time without waiting for equipment detection or data transmission. This is extremely important for maintenance, and can detect oil level abnormalities in time and take corresponding measures. In addition, the oil level gauge window 9 is highly reliable, easy to maintain, and low in cost.

[0042] Furthermore, the oil level gauge window 9 is provided with a scale for marking the amount of oil.

[0043] It should be noted that, in addition to clarifying the oil level data, the setting of the scale can also be used to compare the parameters obtained by the host computer 12 , thereby ensuring the accuracy of the oil level parameters in the host computer 12 .

[0044] Furthermore, a control valve 2 is provided on the pipeline 3 connecting the main container 1 and the device under test.

[0045] It should be noted that the setting of the control valve 2 is intended to accurately adjust the oil flow in the pipeline 3 to ensure that the oil enters the main container 1 at the required rate, thereby achieving precise control of the oil level. Secondly, in maintenance, overhaul or emergency situations, the control valve 2 can be closed to isolate the main container 1 from the equipment under test, prevent the oil from continuing to flow, and protect the safety of the equipment and operators. Finally, by adjusting the opening of the control valve 2, the pressure in the pipeline 3 can be controlled to prevent damage to the equipment or affect the accuracy of oil level detection due to excessive or insufficient pressure.

[0046] Furthermore, the control valve 2 is an electric control valve 2 , which is connected to a programmable logic controller 11 . The programmable logic controller 11 controls the opening of the electric control valve 2 under the control of a host computer 12 .

[0047] The electric control valve 2 is used to achieve automatic control; through the control of the host computer 12, the opening of the electric control valve 2 can be adjusted remotely and automatically, thereby achieving precise control of the oil flow and pressure and improving the automation of the system. At the same time, the electric control valve 2 usually has a high control accuracy and can respond to small changes in opening, thereby ensuring the accuracy and stability of oil level detection. Centralized control and management of the entire oil level monitoring system is achieved, and the operation and maintenance efficiency of the system is improved.

[0048] Furthermore, the pipeline 3 is connected to the device under test through the flange 4 .

[0049] It should be noted that the flange 4 connection can provide a stable and reliable connection method, ensure a tight connection between the pipeline 3 and the device under test, and prevent medium leakage. Moreover, the flange 4 connection has a standardized design, and is relatively easy to install and disassemble, which can greatly improve work efficiency and reduce installation and maintenance costs. In addition, the flange 4 connection can achieve complete compliance with stress distribution and has a high sealing performance, thereby effectively preventing the leakage of liquid or gaseous media and ensuring the safe operation of the pipeline 3 system. At the same time, the flange 4 connection has a high connection strength and reliability, is not easy to loosen, fall off or fail after installation, and can maintain a stable connection state for a long time.

[0050] Furthermore, the programmable logic controller 11 is wirelessly connected to the magnetic induction device 8 via the wireless transceiver 10. The wireless connection gets rid of the limitation of physical cables, so that the communication between the PLC and the magnetic induction device 8 is no longer restricted by distance and position, allowing the operator to monitor directly indoors, further reducing the burden on the operator.

[0051] Furthermore, an alarm connected to the programmable logic controller 11 by wire or wirelessly. Specifically, based on the preset oil level threshold in the programmable logic controller 11, the alarm is triggered to alarm, and the staff is reminded to maintain the reducer in time.

[0052] Furthermore, a drain port 7 is provided at the lower end of the main container 1 , and the drain port 7 is sealed by a lower cover 6 .

[0053] The drain port 7 is used to conveniently and quickly drain the oil in the main container 1, meeting the needs of daily maintenance and operation. When it is not necessary to drain the liquid, the drain port 7 is sealed by the lower cover 6 to isolate the inside and outside of the container, prevent foreign impurities from entering the container or liquid leakage, and ensure the purity and safety of the liquid in the container.

[0054] Furthermore, the main body container 1 is cylindrical. The advantages of the cylindrical main body container 1 are that it has a simple and stable structure, can effectively withstand internal pressure, and ensure the safety of the container; at the same time, it has a high space utilization rate, can maximize storage capacity, and reduce space waste; in addition, the cylindrical design is easy to manufacture and maintain, reduces costs, and has strong adaptability, can be widely used in a variety of industrial occasions, and also shows good anti-deformation ability in the face of natural disasters, which guarantees the safety of stored substances to a certain extent.

[0055] In summary, the embodiments of the utility model provide an oil level gauge that can be remotely monitored, including: utilizing a programmable logic controller 11 to remotely transmit the liquid level data of the oil level gauge to a host computer 12, thereby facilitating the lubrication control of important equipment by maintenance personnel and inspection personnel, reducing the daily workload of maintenance personnel, and improving the automation level of the equipment. When a sudden drop in the oil level of the equipment affects the normal operation of the equipment, it can be discovered in time, thereby preventing the failure of equipment lubrication from causing an accident to expand, thereby improving safety.
