Embodiment Construction

[0014] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 2 As shown, the present invention is a detection device for automatically adjusting the installation angle of a radar level gauge, which includes a radar level gauge 2 , a linear actuator 3 and a controller 4 . The silo 1 includes a cylindrical structure in the upper half and a conical structure in the lower half. The radar level gauge 2 is located on the top of the silo 1, and is set offset to avoid the position of the feeding hole in the middle of the silo. The linear actuator 3 includes a horizontal tie rod that can be stretched back and forth horizontally. One end of the horizontal tie rod is fixedly connected with the radar level gauge 2 and drives the radar level gauge 2 to rotate around a fixed fulcrum. The above-mentioned straight stroke actuator 3 and radar level gauge 2 are respectively connected with the con...

Abstract

The invention discloses a detection device for automatically adjusting the installation angle of a radar level gauge, which comprises a radar level gauge located on the top of a silo and a straight-stroke actuator that drives the radar level gauge to rotate, and the straight-stroke actuator can move back and forth horizontally Move, and drive the radar level gauge to rotate around the fixed fulcrum; the linear actuator and the radar level gauge are respectively connected to the controller, and the radar level gauge transmits the detected material level distance signal to the controller, directly The travel actuator transmits the horizontal execution travel signal to the controller. The invention utilizes the straight-stroke actuator to drive the radar level gauge to rotate, and at the same time, the controller obtains the optimal tilt angle of the radar level gauge according to the material level distance signal of the radar level gauge and the horizontal execution stroke of the straight-stroke actuator, and according to The optimal inclination angle corrects the real material level value of the silo, so that when the radar level gauge is installed away from the feeding hole in the center of the silo and measures the material level of the silo with a cone section, the measurement accuracy can be greatly improved.

Description

technical field [0001] The invention relates to an instrument installation detection device, in particular to a detection device for automatically adjusting the installation angle of a radar level gauge. Background technique [0002] Usually, in most projects, the upper half of the solid material buffer bin is a cylinder, the lower half is a cone, and the top of the bin is filled in the middle, such as figure 1 shown. In order to continuously detect the material level of the silo, the radar material level gauge is widely used at present. In order to avoid the material flow, the radar level gauge can only be installed away from the feeding hole in the middle. If the radar level gauge is installed vertically, the radar wave will be emitted on the cone section at the bottom of the silo and cannot detect the bottom of the silo. In the prior art, a radar level gauge with a universal flange is usually used, and its installation angle can be manually adjusted so that it is roughl...
