Description

Technical Field

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

[0002] Radar level meters are measuring instruments based on the time-travel principle. A probe emits a high-frequency pulse that propagates at the speed of light. When the pulse hits the surface of a material, it reflects back and is received by a receiver within the meter. By measuring the time difference between emission and reception, combined with the velocity of the beam, the distance between the material surface and the sensor can be determined, and thus the liquid level and material level. Radar level meters are widely used in industry and water conservancy. In this industry, radar level meters, with their non-contact, high-security, and high-precision characteristics, have become an indispensable component of water conservancy monitoring systems. They can provide continuous monitoring at key locations such as rivers, bridges, reservoirs, and sluice gates. However, because these measurement areas often have large detection ranges and complex, dynamically changing monitoring environments, conventional fixed brackets are used to secure radar level meters. This results in a fixed and limited monitoring range, which no longer meets practical needs. There is an urgent need to develop a mounting bracket that can improve the adaptability of radar level meters to complex monitoring environments and enable large-scale monitoring. Utility Model Content

[0003] In view of this, in order to solve the above technical problems, the utility model proposes an adjustable bracket device for a radar level meter. Through reasonable structural design, it has the functions of lifting, steering, and telescoping, which can effectively expand the monitoring range of the radar level meter and improve the adaptability of the radar level meter.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0009] An extension mechanism includes a mounting beam connected to the rotating end of the rotating assembly, an extension assembly mounted on the mounting beam and extendable in the horizontal direction, and a radar level meter is mounted on the extension end of the extension assembly.

[0010] The extension mechanism can be extended forward in the horizontal direction, and the rotation mechanism can be rotated in the horizontal direction to achieve steering, thereby effectively expanding the monitoring range of the radar level meter and enabling monitoring in multiple positions with higher accuracy and greater adaptability. At the same time, a lifting mechanism is provided to adjust the height of the radar level meter to adapt to different monitoring environments.

[0011] Furthermore, the lifting assembly includes a driving motor installed on the top of the column shell, a screw installed in the inner cavity of the column shell and driven by the driving motor, a screw nut mounted on the screw, and a sliding seat connected to the screw nut; the side wall of the column shell is provided with a vertical sliding groove, the bottom of the sliding seat passes through the sliding groove and extends into the inner cavity of the column shell and is fixed to the screw nut, and the movable seat is fixed on the end face of the sliding seat.

[0013] Furthermore, the rotating assembly includes a mounting base fixed on the movable base, a rotating column rotatably mounted on the mounting base, and a driving motor for driving the rotating column to rotate; the upper end of the rotating column is fixedly connected to one end of the mounting beam.

[0014] The second driving motor drives the rotating column to rotate, and the mounting beam connected to the rotating column is driven to rotate in the horizontal direction with the rotating column as the center, thereby realizing the rotation of the radar level meter and expanding the monitoring range.

[0015] Furthermore, the upper end surface of the mounting seat is provided with a mounting groove, and the bottom of the rotating column is rotatably mounted in the mounting groove through a rotating bearing; the outer side wall of the rotating column is circumferentially provided with a circle of racks, and the output end of the driving motor 2 is installed with a gear meshing with the rack; the rotating column is fixed to one end of the mounting beam by means of flange bolts.
