[0002] at present,

[0003] As an important tool for liquid storage and transportation, oil drums are widely used in various fields such as industry, agriculture, and life. In the process of using oil drums, accurately grasping the liquid level in the drum is of great significance to ensure production safety and improve use efficiency.

[0004] However, traditional liquid level detection methods can often only provide a single liquid level information, and cannot accurately measure the liquid level at different positions inside the oil barrel, which limits the application scope and accuracy of liquid level detection to a certain extent. For example, the Chinese patent with patent number CN219265426U discloses a non-destructive oil barrel liquid level telemetry system, which is applied to the oil barrel. The oil barrel includes a barrel body and an oil cover; an oil port is provided on the top surface of the barrel body; the non-destructive oil barrel liquid level telemetry system includes a threaded connector, a liquid level sensor, an NB-IoT wireless module, a wireless base station, a cloud platform and a user terminal.

This limitation may lead to misjudgment of the liquid amount in the oil barrel, thereby affecting the accuracy of inventory management and safety monitoring. Utility Model Content

DETAILED DESCRIPTION

[0038] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] like Figures 1 to 6As shown, an oil barrel liquid level telemetry system is applied to an oil barrel, and the oil barrel includes a barrel body 7; the oil barrel liquid level telemetry system includes an oil barrel connector 1, a collection and communication control box 2, a liquid level sensor 3, a data platform 4, and a user terminal 5; the oil barrel liquid level telemetry system has a simple structure, and the oil barrel connector 1, the collection and communication control box 2, the liquid level sensor 3, the data platform 4, and the user terminal 5 of the oil barrel liquid level telemetry system, the structural parts and software used are mature and reliable, and most of them are common and easily available structures on the market, with low cost, which is more conducive to market promotion and application. The oil barrel connector 1 is threadedly connected to the top surface of the barrel body 7; through the threaded connection between the oil barrel connector 1 and the top surface of the barrel body 7, the structural connection is stable and reliable, the structure is simple, and the disassembly and assembly are convenient, which is convenient for stable detection of the liquid level in the oil barrel, thereby achieving the effect of remote monitoring and management. The collection and communication control box 2 is connected to the oil barrel connector 1 and is electrically connected to the liquid level sensor 3; the collection and communication control box 2 is connected to the data platform 4 for data communication; the data platform can be a cloud platform such as Alibaba Cloud, Huawei Cloud, and Baidu Cloud. The user terminal 5 is connected to the cloud platform for data communication and is used for user operation; the liquid level sensor 3 includes a detection rod 31 and a floating liquid level sensing element 32. The detection rod 31 is connected to the lower end of the oil barrel connector 1; at least three floating liquid level sensing elements 32 are arranged from the bottom end of the detection rod 31 to the top end thereof, and are used to detect the liquid level at the corresponding position of the barrel body 7.

[0040] The oil barrel liquid level telemetry system improves the liquid level sensor 3, combines the detection rod 31 and the floating liquid level sensing element 32 to form the liquid level sensor 3, and arranges at least three floating liquid level sensing elements 32 from the bottom end of the detection rod 31 to the top end thereof, which can monitor the liquid level at multiple positions in the oil barrel in real time, realizes the monitoring of the liquid level at multiple positions in the oil barrel, improves the accuracy and comprehensiveness of the liquid level detection, and more accurately reflects the actual situation of the liquid level in the oil barrel. At the same time, by setting up the oil barrel connector 1, the acquisition communication control box 2, the liquid level sensor 3, the data platform 4, and the user terminal 5, the liquid level sensor 3 detects the liquid level at different positions in the oil barrel, forms a liquid level signal, and feeds it back to the acquisition communication control box 2. Then, after the acquisition communication control box 2 receives the liquid level signal, it sends the data to the data platform 4. Then, the data platform 4 stores, processes and analyzes the received liquid level signal, generates a liquid level change curve, liquid level alarm and other information, and displays it to the user through the display module. The user can view the liquid level information and receive alarm information at any time through the user terminal 5 device, thereby realizing remote monitoring and management of the liquid level of the oil barrel, improving work efficiency, reducing manual intervention, and reducing safety hazards.

[0041] In this embodiment, there are three float liquid level sensing elements 32; one of the float liquid level sensing elements 32 is located at the bottom end of the detection rod 31, and the other two float liquid level sensing elements 32 are respectively located at the middle upper end and the top end of the detection rod 31. By designing the positions of the three float liquid level sensing elements 32 on the detection rod 31 in this way, they correspond to the low, middle and high liquid levels in the oil barrel, respectively, so as to realize the monitoring of the liquid levels at different positions in the oil barrel. Of course, the number of float liquid level sensing elements 32 on the detection rod 31 can be reasonably designed according to the needs.

[0042] In this embodiment, the float level sensing element 32 includes an upper limit spring 321, a lower limit spring 322, a reed switch 323, a magnetic ring 324 and a float 325; the upper limit spring 321 and the lower limit spring 322 are installed on the detection rod 31 from top to bottom; the upper limit spring 321 and the lower limit spring 322 are installed on the detection rod 31 as fixed points, which limit the up and down movement range of the magnetic ring 324 and the float 325. The reed switch 323 is installed on the detection rod 31 and is located below the upper limit spring 321, and is electrically connected to the acquisition communication control box 2; the reed switch 323 is responsible for converting the state change of the magnetic ring 324 into an electrical signal output. The magnetic ring 324 can be slidably sleeved on the detection rod 31 and can reciprocate along the up and down direction of the detection rod 31, and can be magnetically attracted to the reed switch 323; the magnetic ring 324 can slide freely along the detection rod 31 and interact with the reed switch 323. The float 325 is sleeved on the outer peripheral side of the magnetic ring 324, and is used to drive the magnetic ring 324 to reciprocate along the up and down direction of the detection rod 31. The core components of the float liquid level sensing element 32 include an upper limit retaining spring 321, a lower limit retaining spring 322, a reed switch 323, a magnetic ring 324 and a float 325. Among them, the float 325 is installed on the outside of the magnetic ring 324, and floats up and down with the change of the liquid level. When the liquid level in the oil barrel rises, the float 325 rises accordingly, pushing the magnetic ring 324 to move upward. When the magnetic ring 324 approaches or contacts the reed switch 323, the magnetic attraction between the two causes the state of the reed switch 323 to change, thereby triggering the output of the electrical signal, specifically forming a liquid level signal output. Conversely, when the liquid level drops, the float 325 and the magnetic ring 324 also drop, the reed switch 323 returns to its original state, and stops outputting electrical signals. The design principle of the float liquid level sensing element 32 is simple and efficient. It uses the buoyancy principle to achieve liquid level detection without the need for complex mechanical structures or electronic components, thereby reducing the failure rate and maintenance costs. Secondly, the float liquid level sensing element 32 has a fast response speed and can reflect liquid level changes in real time, making it suitable for occasions that require a quick response. In addition, the float liquid level sensing element 32 has high accuracy and stability. Through precise component design and installation, it can achieve accurate measurement of the liquid level height and has good long-term operating stability.

Then, after the control board 22 receives the liquid level signal and the power signal from the power supply module 24, it forms data and sends these data to the data platform 4 through the wireless communication module 23. Then, the data platform 4 stores, processes and analyzes these data, generates liquid level change curves, liquid level alarms and other information, and displays them to the user through the display module. The user can view the liquid level information and receive alarm information at any time through the user terminal 5 device, thereby realizing remote monitoring and management of the liquid level of the oil barrel, improving work efficiency, reducing manual intervention, and reducing safety hazards.
