Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid level meters, in particular to a remote intelligent liquid level meter. Background Art
[0002] Float level gauge The float level gauge mainly uses the principle of the float floating up and down on the liquid surface to measure the liquid level. Due to its simple working principle, simple structure, high reliability and stability, it is widely used in chemical, petroleum, food processing and other industries.
[0003] In addition, the communication interface set on the float level gauge can be used to communicate with other devices or systems, such as data transmission and remote monitoring through serial ports, Ethernet, Modbus and other protocols to achieve remote intelligent monitoring.
[0004] In the related art, due to the accuracy requirements of the float type liquid level meter, a small gap needs to be maintained between the float and the float rod to ensure that the movement of the float in the liquid can be accurately transmitted to the measuring device, which can prevent measurement errors caused by excessive gaps.
[0005] However, when the gap is too small, the contact area between the float and the float rod increases, and the float may get stuck on the float rod, causing measurement errors. In addition, when liquid is poured into or discharged from the container, measurement errors may also be caused by liquid flow and float rotation. Therefore, the accuracy of existing float-type liquid level meters in dynamic measurements needs to be improved. Summary of the invention
[0006] The utility model aims to solve one of the technical problems in the above-mentioned technology at least to a certain extent.
[0007] To achieve the above-mentioned purpose, the utility model proposes a remote intelligent liquid level meter in the first aspect, comprising: a mounting head, a float rod, a magnetic sensor, a magnetic float, a signal converter, a threaded joint and a baffle sleeve, wherein the float rod is arranged in the mounting head, and a plurality of slide grooves are provided at equal angles along the length direction on the outer wall of the float rod; the magnetic sensor is arranged at the top of the mounting head, and the signal converter is connected to the magnetic sensor; the magnetic float is provided with a through groove along the central axis, a plurality of rollable balls are embedded on the inner wall of the through groove, and the plurality of balls correspond to the plurality of slide grooves one by one, the magnetic float is sleeved on the float rod, and the balls are rolled in the corresponding slide grooves; the threaded joint is coaxial with the float rod and is arranged in the mounting head; the baffle sleeve is sleeved outside the float rod and is threadedly connected to the threaded joint, wherein a connecting notch is provided at the bottom of the baffle sleeve, and an exhaust notch is provided at the top of the baffle sleeve.
[0008] In addition, the remote intelligent liquid level meter proposed in the utility model may also have the following additional technical features:
[0009] As a further description of the above technical solution: the signal converter has a built-in communication interface.
[0010] As a further description of the above technical solution: two detachable limit rings are arranged on the float rod, and the magnetic float is arranged on the float rod between the two limit rings.

DETAILED DESCRIPTION
[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0025] The remote intelligent liquid level meter according to the embodiment of the utility model is described below with reference to the accompanying drawings.
[0026] like Figure 1 and Figure 2 As shown, the remote intelligent liquid level meter of the embodiment of the utility model may include a mounting head 100 , a float rod 200 , a magnetic sensor 300 , a magnetic float 400 , a signal converter 500 , a threaded joint 600 and a choke sleeve 700 .
[0027] The float rod 200 is disposed in the mounting head 100 , and a plurality of slide grooves 201 are provided on the outer wall of the float rod 200 at equal angles along the length direction.
[0028] As a possible scenario, a threaded groove is provided on the outer wall of the mounting head 100 so as to be threadedly connected to the mounting position of the liquid container 800 .
[0029] The magnetic sensor 300 is disposed on the top of the mounting head 100 , and the signal converter 500 is connected to the magnetic sensor 300 .
[0030] It should be noted that the magnetic sensor 300 transmits the detected position signal of the magnetic float 400 to the signal converter 500. The signal converter 500 amplifies, filters, linearizes, and other processes the signal acquired by the magnetic sensor 300 to improve the quality and stability of the signal and ensure that it meets the input requirements of the electronic device. The conditioned physical signal is then converted into a standard electrical signal, usually an analog signal (such as a voltage or current signal), and the converted electrical signal is output to an external electronic device, such as a data acquisition system, a display screen, a controller, etc.
[0031] like Figure 4 and Figure 5 As shown, the magnetic float 400 is provided with a through groove 401 along the central axis, and a plurality of rollable balls 402 are embedded on the inner wall of the groove 401, and the plurality of balls 402 correspond one by one to the plurality of slide grooves 201. The magnetic float 400 is sleeved on the float rod 200, and the balls 402 are rolled in the corresponding slide grooves 201.
[0032] As a possible situation, the number of the slide grooves 201 is three, and the three slide grooves 201 are arranged at an angle of 120 degrees along the axial direction of the float rod 200, and the number of the balls 402 is also correspondingly three.
[0033] The threaded joint 600 is coaxial with the float rod 200 and is disposed in the mounting head 100 . The baffle sleeve 700 is sleeved outside the float rod 200 and is threadably connected to the threaded joint 600 .
[0034] Among them, Figure 3 As shown, a communication slot 701 is provided at the bottom of the baffle sleeve 700 , and an exhaust slot 702 is provided at the upper portion of the baffle sleeve 700 .
[0035] Specifically, if Figures 1 to 6 As shown, when the relevant staff installs the remote intelligent liquid level meter of the utility model, first, the relevant staff screws the baffle sleeve 700 into the threaded joint 600, and then installs the mounting head 100 at the mounting position of the liquid container 800, and then the float rod 200, the magnetic float 400, and the baffle sleeve 700 are all extended into the liquid container 800.
[0036] When the liquid level in the liquid container 800 changes, the magnetic float 400 floats on the liquid surface and moves on the float rod 200 following the change in the liquid level. At this time, the ball 402 rolls in the corresponding slide groove 201. Since the contact area between the ball 402 and the slide groove 201 is smaller, the jamming scene can be effectively reduced.
[0037] When the liquid container 800 is filled or discharged, since the connecting slot 701 is connected to the liquid container 800, the liquid level change in the liquid container 800 is consistent with the liquid level change in the baffle sleeve 700, and due to the blocking effect of the baffle sleeve 700, the impact of the flowing liquid on the magnetic float 400 can be effectively blocked. Since the ball 402 is limited in the slide groove 201 and cooperates with the blocking effect of the baffle sleeve 700, the rotation of the magnetic float 400 caused by the flow of liquid can be avoided, and the shaking of the magnetic float 400 caused by the impact of the flowing liquid on the magnetic float 400 is reduced. The change of the exposed area of the surface is smaller, and the buoyancy of the magnetic float 400 is more stable, thereby ensuring the accuracy of the liquid level measurement.
[0038] In one embodiment of the present invention, the signal converter 500 has a built-in communication interface, which can be used to communicate with other devices or systems, such as data transmission and remote monitoring through serial ports, Ethernet, Modbus and other protocols to achieve remote intelligent monitoring.
[0039] In one embodiment of the utility model, two detachable limit rings 202 are provided on the float rod 200, and the magnetic float 400 is arranged on the float rod 200 between the two limit rings 202. Relevant staff can adjust the positions of the two limit rings 202 in advance according to the actual measurement range.
[0040] It should be noted that the two limit rings 202 can limit the movement range of the magnetic float 400 within the measuring range to ensure that the float does not exceed the designed liquid level range, thereby preventing the magnetic float 400 from excessively moving inside the liquid level meter, thereby causing inaccurate measurement results or damaging the equipment.
[0041] In addition, the limit ring 202 can also protect the magnetic float 400. When the magnetic float 400 approaches the upper and lower limits of the liquid level meter, the limit ring 202 can prevent the magnetic float 400 from continuing to move up or down, thereby avoiding collision or damage between the magnetic float 400 and other components inside the liquid level meter.
[0042] In one embodiment of the present invention, an external thread is provided on the outer wall of the threaded joint 600, and an internal thread is provided on the top inner wall of the baffle sleeve 700, wherein the internal thread is threadably connected to the external thread, wherein the exhaust notch 702 is lower than the position of the internal thread.
[0043] It can be understood that when the remote intelligent liquid level gauge of the embodiment of the utility model is installed at the installation position of the liquid container 800, the baffle sleeve 700 extends into the liquid container 800. When the liquid flows into the baffle sleeve 700, the air in the baffle sleeve 700 is discharged from the exhaust slot 702. Then, the air pressure in the baffle sleeve 700 always remains consistent with the air pressure in the liquid container 800, so that the measurement accuracy of the liquid level is more accurate.
[0044] In summary, according to the remote intelligent liquid level meter of the embodiment of the utility model, a slide groove 201 is opened on the float rod 200, and a rotatable ball 402 is arranged in the magnetic float 400, so that the ball 402 rolls in the slide groove 201, which can not only reduce the contact area between the magnetic float 400 and the float rod 200 and reduce the jamming, but also, due to the axial limitation of the magnetic float 400 by the slide groove 201, the rotation of the magnetic float 400 can be avoided. By setting the flow-blocking sleeve 700 outside the float rod 200, the influence of liquid flow on the float can be reduced, so as to improve the accuracy of dynamic measurement.
