Description

Technical Field

[0001] The invention relates to the technical field of liquid level meters, and in particular to a wireless remote transmission liquid level meter. Background Art

[0002] Wireless remote level meter is a device that uses wireless communication technology to monitor liquid level. It has an LCD display screen, which is convenient for reading data and configuring parameters on site. Wireless remote level meter can transmit liquid level data to the monitoring center in real time without wiring, and is suitable for environments where it is inconvenient to pull wires on site. It usually has multiple wireless transmission methods such as GPRS, 4G, NB-IoT, LoRa, etc., and is suitable for various industrial environments.

[0003] Among them, non-contact level meters are suitable for various media, including liquid, slurry and granular material level monitoring, such as radar level meters, ultrasonic level meters and laser level meters. The height of the liquid level usually refers to the distance between the liquid surface and the reference plane (usually the ground is used as the reference plane). The non-contact level meter detects the distance from the liquid surface to the level meter by sending a signal and receiving the reflected signal. If the distance between the level meter and the reference plane is known, the height of the liquid surface can be obtained through simple mathematical calculations.

[0004] This type of level meter needs to be installed perpendicular to the surface of the measured medium. If the level meter is not installed perpendicularly, it will cause measurement errors and affect the accuracy of the measurement results. Fig.11 As shown in the figure, in a horizontal state, the height of the level gauge from the ground is H, and the distance measured by the level gauge is G, then the liquid level height L = HG. Fig.12 As shown in the figure; the container is tilted, although the liquid surface remains horizontal, the total volume of the liquid in the container remains unchanged and the liquid surface height will change. The actual height of the liquid level is L1=H-G1. Since the liquid level gauge is not perpendicular to the liquid surface at this time, the distance measured by the liquid level gauge is G2. At this time, the liquid level height is L3=H-G2. Since G2>G1, L3<L1, and the result has a large error.

[0005] At present, container tilting can be caused by many factors, such as uneven force causing center of gravity shift, unstable supporting structure, external environmental influence, etc. Container tilting not only easily increases the actual liquid level measurement error, but also easily makes the pressure distribution inside the container uneven, resulting in stress concentration, thus affecting the structural integrity and safety of the container.

[0006] Based on the above problems, the present invention proposes a wireless remote liquid level meter. Summary of the invention

[0007] The purpose of the present invention is to provide a wireless remote liquid level meter that can detect the actual liquid level height throughout the entire process with high measurement accuracy. It can also monitor container tilt and liquid leakage without adding other monitoring equipment, and can promptly remind staff to take measures when the container tilts or liquid leaks, thereby ensuring the structural integrity and safety of the container and saving costs at the same time.

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Embodiment 1

[0044] This embodiment provides Figure 7 The wireless remote liquid level meter shown is installed on the top of a container 40 . The container 40 includes a tank body 41 and a tank top 42 arranged on the top of the tank body 41 . A butt joint 43 is fixed to one side of the top of the tank top 42 .

[0045] The wireless remote liquid level meter of the first embodiment specifically includes a liquid level detection unit 10 and a support plate 31;

[0046] like Figure 4 As shown, the liquid level detection unit 10 includes a liquid level meter 11, and the liquid level meter 11 is wirelessly connected to the remote control terminal, and the wireless transmission mode can be selected from GPRS, 4G, NB-IoT, LoRa, etc.;

[0047] A level gauge flange 13 is fixed on the outside of the level gauge 11, and an outer sleeve 14 is fixed on the bottom of the level gauge flange 13. The outer sleeve 14 is a retractable and bendable pipe, such as a corrugated pipe;

[0048] A mounting flange 15 is fixed at the bottom of the outer sleeve 14. The outer sleeve 14 and the mounting flange 15 are both arranged outside the antenna 12 of the liquid level meter 11. The liquid level detection part 10 is connected to the butt joint 43 through the mounting flange 15.

[0049] The support plate 31 is arranged on the top of the liquid level detection part 10 to support the liquid level detection part 10. The support plate 31 is fixed on a fixed object, such as a ceiling or wall of a workshop. The liquid level gauge flange 13 is fixed to one side of the bottom of the support plate 31 through a mounting rod 16.

[0050] The detection principle of the actual liquid level in the container 40 in the first embodiment is:

[0051] The support plate 31 is installed on the fixed objects around the container 40, such as the ceiling and wall of the workshop, and then the level gauge flange 13 on the level gauge 11 is fixed to the support plate 31 by the installation rod 16. The level gauge 11 is installed horizontally with the ground as the reference plane so that the antenna 12 is perpendicular to the ground (the level gauge 11 can be detected by a level meter or other equipment to see whether it is installed horizontally). Then the container 40 is moved to the bottom of the level gauge 11, and the installation flange 15 on the level gauge 11 is connected to the butt pipe 43;

[0052] When the container 40 is tilted due to uneven force applied, resulting in the displacement of the center of gravity, unstable supporting structure, external environmental influence, etc., the liquid level gauge 11 is fixed, and the liquid level height changes, such as Figure 8 As shown, at this time, the height of the liquid level gauge 11 from the liquid surface is B, and the height of the liquid level gauge 11 from the ground is A (which can be measured by a distance measuring device after the liquid level gauge 11 is installed on the support plate 31). At this time, the actual height of the liquid surface is C=AB.

[0053] The state of the wireless remote liquid level meter of the first embodiment does not change with the change of the container 40, and can be kept vertical to the liquid surface at any time, thereby realizing the full detection of the actual liquid level height, and the measurement accuracy is high.

[0054] Embodiment 2

[0055] This embodiment 2 provides Figure 1-3 The wireless remote liquid level meter shown is installed on the top of a container 40. The container 40 whose liquid level needs to be detected includes a tank body 41 and a tank top 42 arranged on the top of the tank body 41. Both sides of the top of the tank top 42 are fixed with butt joints 43.

[0056] The wireless remote liquid level meter of the second embodiment specifically includes a liquid level detection unit 10 , a liquid level detection unit 20 and a support unit 30 .

[0057] like Figure 4 As shown, the liquid level detection part 10 includes a liquid level meter 11, which is wirelessly connected to the remote control terminal, and the wireless transmission mode can be selected from GPRS, 4G, NB-IoT, LoRa, etc.; a liquid level meter flange 13 is fixed on the outside of the liquid level meter 11, and an outer sleeve 14 is fixed at the bottom of the liquid level meter flange 13. The outer sleeve 14 is a retractable and bendable pipe, such as a corrugated pipe; a mounting flange 15 is fixed at the bottom of the outer sleeve 14, and the outer sleeve 14 and the mounting flange 15 are both arranged on the outside of the antenna 12 of the liquid level meter 11, and the liquid level detection part 10 is connected to one of the butt pipes 43 through the mounting flange 15.

[0058] like Figure 5As shown, the liquid level detection part 20 is arranged on one side of the liquid level detection part 10, and the liquid level detection part 20 includes a liquid level gauge 21, and the liquid level gauge 21 is wirelessly connected to the remote control terminal, and the wireless transmission mode can be selected from GPRS, 4G, NB-IoT, LoRa, etc.; a liquid level gauge flange 23 is fixed on the outside of the liquid level gauge 21, and an outer protective tube 24 is fixed at the bottom of the liquid level gauge flange 23. The outer protective tube 24 uses a retractable and bendable pipe, such as a corrugated tube; a mounting flange 27 is fixed at the bottom of the outer protective tube 24, and the outer protective tube 24 and the mounting flange 27 are both arranged on the outside of the antenna 22 of the liquid level gauge 21, and the liquid level detection part 20 is connected to another docking pipe 43 through the mounting flange 27;

[0059] At least one group of floating block structures 25 are also provided on the outside of the second liquid level detection part 20. The floating block structures 25 are provided on the inside of the outer protective tube 24 and the second mounting flange 27. The floating block structures 25 include a vertical rod 251 and a floating block 252 fixed to the bottom of the vertical rod 251. In practice, the vertical rod 251 can be a telescopic rod, preferably an electric telescopic rod such as an electric cylinder or an electric push rod. When the second liquid level detection part 20 and the container 40 are installed, the vertical rod 251 is contracted to shorten the overall length of the second liquid level detection part 20, thereby facilitating the installation of the second liquid level detection part 20 and the container 40. After the installation is completed, the vertical rod 251 is extended to allow the floating block 252 to contact the top of the liquid surface.

[0060] Then, if Figure 6 As shown, the support part 30 is arranged on the top of the liquid level detection part 10 and the liquid level detection part 20 to support the liquid level detection part 10 and the liquid level detection part 20, the support part 30 includes a support plate 31, the liquid level gauge flange 13 is fixed to one side of the bottom of the support plate 31 through the mounting rod 16, a top plate 32 is provided on the top of the support plate 31, at least one telescopic rod 34 is fixed on the top of the top plate 32, a fixing plate 35 is fixed on the top of the telescopic rod 34 to fix the support part 30 on a fixed object, the telescopic rod 34 can be telescoped to install the fixing plate 35 on the ceiling, wall, etc. of the workshop, and the telescopic rod 34 needs to be fixed in length after the telescopic rod 34 is telescoped. You can choose to use threads to connect the rods of the telescopic rod 34, or you can choose to use bolts to tighten the rods of the telescopic rod 34.

[0061] The second liquid level detection part 20 is slidably connected to the support part 30, so that the second liquid level gauge flange 23 is slidably connected to the support part 30 through at least one set of guide structures 26. Figure 5As shown, the guide structure 26 includes a track 261 and a slider 262 slidably arranged on the outside of the track 261. The top of the track 261 is fixed to the other side of the bottom of the support plate 31, and the slider 262 is fixed to the level gauge flange 23; the slider 262 is provided with a fixing device 263 capable of fixing the slider 262 and the track 261. The fixing device 263 can be an electric device such as a micro electric cylinder and a micro electric push rod. When the piston rod of the electric device passes through the slider 262 and presses against the outside of the track 261, the slider 262 is fixed to the track 261. When the piston rod of the electric device is separated from the track 261, the slider 262 can slide along the track 261.

[0062] The working principle of the second embodiment is:

[0063] Install the fixing plate 35 on the fixed objects around the container 40, such as the ceiling and wall of the workshop, and then use the installation rod 16 to fix the level gauge flange 13 on the level gauge 11 to one side of the support plate 31, and install and fix the track 261 on the level gauge 21 to the other side of the support plate 31. With the ground as the reference plane, the level gauge 11 and the level gauge 21 need to be installed horizontally so that the antenna 12 and the antenna 22 are perpendicular to the ground, and the bottom end surfaces of the antenna 12 and the antenna 22 need to be kept at the same height, and then use the fixing device 263 to fix the slider 262 and the track 261 so that the level gauge 21 is at a fixed height; then move the container 40 to the bottom of the level gauge 11 and the level gauge 21, and connect the mounting flange 15 on the level gauge 11 and the mounting flange 27 on the level gauge 21 to the two butt pipes 43 on the container 40 respectively;

[0064] When no liquid is injected into the container 40, as Fig. 9 As shown, the liquid level gauge 11 can detect the distance C from the bottom of the container 40, and the liquid level gauge 21 can detect the distance D from the bottom of the container 40. Different values ​​of C and D indicate that the container 40 is tilted during installation, and personnel are required to adjust the installation state of the container 40 until the values ​​of C and D are the same to keep the container 40 installed horizontally.

[0065] Next, the locking of the slider 262 and the track 261 by the fixing device 263 is released, and then the liquid to be stored is injected into the container 40. In the initial state, the floating block structure 25 is at the top of the liquid surface. Fig.10 As shown, at this time, the detection height of the liquid level gauge 11 and the liquid level gauge 21 from the liquid surface is C1, and the height of the liquid level gauge 11 from the ground is A1 (A1 can be measured by a distance measuring device after the liquid level gauge 11 and the liquid level gauge 21 are installed on the support part 30), and the initial height of the liquid surface E=A1-C1;

[0066] Since the float structure 25 changes with the liquid level height, when the height of the float structure 25 changes, the liquid level gauge 21 is driven to move up and down along the guide structure 26, so that the height of the liquid level gauge 21 changes with the liquid level height. Therefore, the distance C1 between the liquid level gauge 21 and the liquid surface remains unchanged, and the initial height A1 of the liquid level gauge 11 and the liquid level gauge 21 from the ground remains unchanged. Therefore, the liquid level gauge 21 detects the initial liquid level height E throughout the whole process.

[0067] When the liquid level changes:

[0068] When the liquid level drops, the height of the liquid level gauge 11 from the liquid level is C2. At this time, the actual height of the liquid level is E1=A1-C2, and E1 is less than E. The data is wirelessly transmitted to the remote control terminal, and the remote control terminal sends a signal to the mobile terminal of the staff to inform the staff that the liquid in the container 40 is leaking or the container 40 is tilted, and remind the staff to take timely measures or adjust the container 40;

[0069] When the liquid level rises, E1 is greater than E, and the data is wirelessly transmitted to the remote control terminal, which then sends a signal to the staff's mobile terminal to inform the staff that the container 40 is most likely tilted, and remind the staff to adjust the container 40 in time.

[0070] In addition, during the monitoring process, in order to detect the liquid level height at different positions in the container 40, such as Figure 5 As shown, a motor 33 is fixedly provided between the support plate 31 and the top plate 32, and the motor 33 is used to drive the liquid level detection part 10 and the liquid level detection part 20 to rotate. The motor 33 selects GPRS, 4G, NB-IoT, LoRa and other wireless transmission methods to wirelessly connect with the remote control terminal. At the same time, in order to improve the rotation stability of the support plate 31, multiple connecting rods can be fixed between the support plate 31 and the top plate 32, and the bottom end of the connecting rod is fixed to the support plate 31, and the top end of the connecting rod is rotatably connected to the top plate 32 through a bearing;

[0071] Furthermore, the container 40 needs to be improved as follows: the tank body 41 and the tank top 42 are rotatably connected through a sealed bearing, and a motor 2 is installed on the tank body 41 to drive the tank top 42 to rotate, and the motor 2 works synchronously with the motor 1 33, and the motor 2 selects GPRS, 4G, NB-IoT, LoRa and other wireless transmission methods to be wirelessly connected to the remote control terminal.

[0072] Motor 1 33 drives liquid level detection unit 10 and liquid level detection unit 20 to rotate, and motor 2 synchronously drives tank top 42 to rotate to change the positions of liquid level gauge 1 11 and liquid level gauge 21 in container 40 to detect the liquid level heights at different positions in container 40. When the liquid level fluctuates, the average of multiple liquid level heights can be taken to reduce the detection error.

[0073] First, the liquid level meter 11 and the liquid level meter 21 of the present invention are liquid level meters such as radar level meters, laser level meters, ultrasonic level meters, etc., which transmit signals for detecting liquid levels;

[0074] Secondly, the present invention can be applied to the storage of dangerous goods. Liquid level gauges must usually be installed on dangerous goods storage containers. For example, GB50074-2014 "Petroleum Depot Design Specifications" stipulates that storage tanks with a capacity greater than 100 cubic meters should be equipped with liquid level measurement and remote transmission instruments; in addition, AQ 3036-2010 "Hazardous Chemical Major Hazard Source Tank Area Site Safety Monitoring Equipment Installation Specifications" requires that storage tanks should be equipped with liquid level monitors; and SH / T 3007-2014 "Petrochemical Storage and Transportation System Tank Area Design Specifications" points out that storage tanks with a capacity greater than 100 cubic meters should be equipped with liquid level continuous measurement and remote transmission instruments.

[0075] In addition, hazardous goods storage containers usually need to be placed horizontally because horizontal placement helps ensure uniform distribution of pressure inside the tank and avoids stress concentration caused by tilting, thereby ensuring the structural integrity and safety of the storage container.

[0076] Since the liquid level meter is a device that must be installed on hazardous material storage containers, the liquid level meter of the present invention can monitor the tilting of the container and the leakage of liquid without adding other monitoring equipment. When the container tilts or leaks liquid, it can promptly remind the staff to take measures, thereby ensuring the structural integrity and safety of the container and saving costs.

[0077] Finally, it should be noted that the present invention is aimed at detecting the case where the inclination angle of the container 40 is small, which is not easy for personnel to detect, and is about 0-15°, rather than a large inclination angle or even the container 40 tipping over. In industrial production, personnel will perform regular maintenance, and the probability of the container 40 having a large inclination angle or even tipping over is extremely low. Therefore, the diameters of the outer sleeve 14 and the outer protective tube 24 need to meet the requirement that the outer sleeve 14 and the outer protective tube 24 do not block the signals of the liquid level gauge 11 and the liquid level gauge 21 when the container 40 is tilted.

[0078] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
