Description

Technical Field

[0001] The utility model belongs to the technical field of radar level meters, in particular to a radar level meter with convenient adjustment of measurement angle. 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 transmission 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 and material levels. Existing radar level meters are primarily installed horizontally. When the measured material is piled, the mounting angle cannot be adjusted. Directly horizontally measuring results in significant errors, affecting measurement accuracy. Utility Model Content

[0009] The mounting frame is fixed to the radar level meter, and the rotating shaft on the mounting frame and the adjustment frame can rotate relative to each other, thereby driving the mounting frame to rotate with the rotating shaft as the center of the circle, thereby adjusting the angle on the front and rear vertical surfaces. Since the movable shaft can slide along the arc groove, it does not affect the rotation of the rotating shaft. After adjusting to the required angle, the movable shaft is fixed to the adjustment frame by tightening the locking nut, thereby fixing the position of the mounting frame, and finally achieving the adjustment of the measuring angle of the radar level meter on the front and rear vertical surfaces;

[0010] The rotating rod and the support frame on the adjustment frame can rotate relative to each other, thereby driving the adjustment frame to rotate with the rotating rod as the center of the circle, so as to adjust the angles on the left and right vertical planes. Since the moving rod can slide along the second arc groove, it does not affect the rotation of the rotating rod. After adjusting to the required angle, the moving rod is fixed to the support frame by screwing and tightening the locking nut, thereby fixing the position of the adjustment frame, and finally realizing the adjustment of the measuring angle of the radar level meter on the left and right vertical planes.

[0014] When the rotating shaft rotates in the rotating shaft hole, the moving shaft slides along the arc groove, which plays a guiding and stabilizing role. After rotating to the required angle, the position is fixed by tightening the locking nut to play a limiting role.

[0015] Furthermore, the adjustment frame includes a left side plate and a right side plate with the arc groove 1, and a rear side plate connecting the left side plate and the right side plate; one end of the rotating rod and the moving rod is fixed on the rear side plate.

[0016] Furthermore, the support frame is an L-shaped plate structure, a rotating rod hole is opened at a position corresponding to the rotating rod, and the arc groove 2 is opened above the rotating rod hole with the rotating rod hole as the center; the rotating rod can be rotatably inserted into the corresponding rotating rod hole.
