Description

Technical Field

[0001] The utility model belongs to the technical field of radar level meters, in particular to a radar level meter fixing device. Background Art

[0002] Radar level meters are key industrial instruments used in a wide range of industries, including chemical, petroleum, grain storage, and water treatment, to measure the height of materials within containers without contact.

[0003] In industrial production, radar level meters are widely used for liquid level measurement. However, existing radar level meter fixing devices can usually only be installed on covered tanks, and there are certain difficulties in installing and fixing uncovered tanks. At the same time, existing fixing devices are also insufficient in maintaining the verticality of the radar level meter, which can easily lead to measurement errors. For this reason, we propose a radar level meter fixing device. Utility Model Content

[0004] In order to solve the problem that the existing radar level meter fixing device can usually only be installed on a tank body with a cover, and there are certain difficulties in installing and fixing the uncovered tank body, and at the same time, the existing fixing device is also insufficient in maintaining the verticality of the radar level meter, which easily leads to measurement errors, the utility model provides the following technical solutions: A radar level meter fixing device includes a connecting plate, cylinders are provided on both sides of the connecting plate, and clamps are provided at the telescopic ends of the two cylinders. A control unit is provided on the connecting plate, a position sensor is provided on the connecting plate, and a radar level meter is installed on the bottom of the connecting plate through a straightening mechanism, and the straightening mechanism is used to adjust the radar level meter to be perpendicular to the liquid surface.

[0005] Preferably, the straightening mechanism includes a support plate, a rotating shaft, a rotating ring, and a fixing part. There are two support plates, and the two support plates are respectively arranged on both sides of the bottom of the connecting plate. A rotating shaft is provided between the two support plates. A rotating ring is rotatably provided on the rotating shaft. Fixing parts are respectively provided on both sides of the rotating ring. A radar level meter is provided at the bottom of the rotating ring. The posture of the radar level meter is adjusted by gravity so that it can remain perpendicular to the liquid surface for measurement.

[0006] Preferably, an electromagnet is provided between the fixing member and the rotating ring, and the rotating ring is made of iron, so as to fix the radar level meter.

[0007] Preferably, two counterweights are symmetrically arranged on the radar level meter, and the two counterweights are bolts with exactly the same structure to prevent the radar level meter from becoming unstable due to device tilt or external force. In addition, the counterweight can be adjusted in position by rotation, thereby achieving fine-tuning of the center of gravity of the radar level meter.

[0008] Preferably, a gasket is provided on the inner side of the splint, and the gasket is designed to be replaceable. Irregular protrusions are provided on the gasket, and the irregular protrusions are made of hard rubber or soft plastic. The distribution design of the irregular protrusions matches the surface shape of the can to be clamped, which helps to reduce damage to the surface of the can and improve the clamping effect.

[0009] Preferably, the connecting plate, supporting plate and rotating shaft are all made of stainless steel or alloy materials, which ensures the strength and corrosion resistance of the device.

[0010] Preferably, the fixing piece is made of polytetrafluoroethylene or a polymer composite material, which helps to reduce friction and wear.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] During operation, the entire device is moved to the top position of the uncovered tank body, and the control unit controls the cylinder to extend to a certain distance to ensure that the splint can exceed the two side edges of the tank body. After the cylinder is extended to the predetermined position, the control unit instructs the cylinder to start contracting, driving the splint to move closer to the tank body. When the splint contacts the outer surface of the tank body, the gasket on the inside of the splint contacts the surface of the tank body, and the irregular protrusions on the gasket increase the friction to ensure that the splint can firmly clamp the tank body during the tightening process to prevent the device from sliding or shifting. The position sensor monitors the position and clamping force of the splint in real time, and feeds back the data to the control unit. After the tank body is firmly clamped, the rotating ring is installed on the rotating shaft and can rotate freely. Due to the action of gravity, the rotating ring will automatically adjust its position so that the radar level meter is naturally perpendicular to the liquid surface, ensuring that the radar level meter can automatically correct to a vertical state even if there is a slight deviation during installation, thereby improving the liquid level measurement. To improve the accuracy of the measurement, after the radar level meter automatically adjusts to the vertical position under the action of gravity, the operator starts the electromagnet through the control unit. After the electromagnet is energized, the rotating ring is firmly adsorbed and locked on the fixing part to prevent the rotating ring from moving during the measurement process, ensuring that the radar level meter remains stable during measurement. If the center of gravity of the radar level meter is found to be slightly offset during installation or use, it may cause the device to be unstable. The operator can adjust the counterweight on the radar level meter. By rotating the counterweight, the position can be fine-tuned to adjust the center of gravity of the radar level meter to ensure that it remains stable and vertical, further improving the measurement accuracy. The radar level meter can be stably installed on uncovered tanks of different diameters and shapes, and the gravity automatic straightening function can be used to ensure that the radar level meter is always perpendicular to the liquid surface, effectively solving the inconvenience of traditional devices in uncovered tank applications and significantly improving the accuracy and reliability of liquid level measurement.

[0020] Two counterweights 13 are symmetrically arranged on the radar level meter 9. The two counterweights 13 are bolts with exactly the same structure to prevent the radar level meter from becoming unstable due to device tilt or external force. In addition, the counterweight 13 can be adjusted in position by rotating it, thereby achieving fine-tuning of the center of gravity of the radar level meter 9.

[0023] The fixing member 8 is made of polytetrafluoroethylene or a polymer composite material, which helps to reduce friction and wear.

[0024] Working principle: When working, the entire device is moved to the top position of the uncovered tank body, and the control unit 4 controls the cylinder 2 to extend to a certain distance to ensure that the splint 3 can exceed the two side edges of the tank body. After the cylinder 2 is extended to the predetermined position, the control unit 4 instructs the cylinder 2 to start contracting, driving the splint 3 to move closer to the tank body. When the splint 3 contacts the outer surface of the tank body, the gasket 12 on the inside of the splint 3 contacts the surface of the tank body.

After the tank body is firmly clamped, the rotating ring 10 is installed on the rotating shaft 7 and can rotate freely. Due to the action of gravity, the rotating ring 10 will automatically adjust its position so that the radar level meter 9 is naturally perpendicular to the liquid surface, ensuring that the radar level meter 9 can automatically correct to a vertical state even if there is a slight deviation during installation, thereby improving The accuracy of liquid level measurement, when the radar level meter 9 automatically adjusts to a vertical position under the action of gravity, the operator starts the electromagnet 11 through the control unit 4. After the electromagnet 11 is energized, the rotating ring 10 is firmly adsorbed and locked on the fixing part 8 to prevent the rotating ring 10 from moving during the measurement process, ensuring that the radar level meter 9 remains stable during measurement. If the center of gravity of the radar level meter 9 is found to be slightly offset during installation or use, it may cause the device to be unstable. The operator can adjust the counterweight 13 on the radar level meter 9. By rotating the counterweight 13, its position can be fine-tuned, thereby adjusting the center of gravity of the radar level meter 9 to ensure that it remains stable and vertical, further improving the accuracy of measurement, and can be stably installed on uncovered tanks of different diameters and shapes. At the same time, the gravity automatic straightening function is used to ensure that the radar level meter 9 is always perpendicular to the liquid surface, effectively solving the inconvenience of traditional devices in uncovered tank applications and significantly improving the accuracy and reliability of liquid level measurement.
