Technical field
The present invention relates to a kind of instrument installation detecting device, more particularly to a kind of adjust automatically radar level gauge setting angle
Detection means.
Background technology
Under normal circumstances, solid material surge bunker upper semisection is cylinder in most of engineerings, and lower semisection is cone, storehouse
The charging of top center, as shown in Figure 1.In order to continuously detect bin-level, widely used at present is radar level gauge.In order to avoid
Stream, radar level gauge can only avoid the charging aperture installation of center, if radar level gauge is vertically-mounted, radar wave will be launched
Bin bottom can not be detected in the cone section of feed bin bottom.Generally use carries the radar material position of universal flange in the prior art
Meter, which can manually adjust its setting angle, makes it roughly be directed at bin bottom.But Adjustment precision is low, essence is unable to reach
Quasi- control, it is higher for the skill set requirements of operating personnel.
It would therefore be highly desirable to solve the above problems.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of radar level gauge setting angle can be caught automatically and correct reality
The detection means of the adjust automatically radar level gauge setting angle of border material position value.
Technical scheme：To realize object above, the invention discloses a kind of adjust automatically radar level gauge setting angle
Detection means, including the radar level gauge at the top of feed bin and the Direct Travel executing agency of drive radar level gauge rotation,
The Direct Travel executing agency can level move back and forth, and drive radar level gauge rotated around fixed pivot；The executing agency and
Radar level gauge is connected with controller respectively, the radar level gauge by the material position distance signal transmission of detection to controller,
Level is performed stroke signal and transmitted to controller by Direct Travel executing agency.
Wherein, the Direct Travel executing agency is K apart from the vertical range of fixed pivot, the water of the Direct Travel executing agency
The flat stroke that performs is S, and the rotation angle of inclination of the radar level gauge is α, wherein
Preferably, the controlling level H in the feed bin, whereinL is radar material position
Count the material position distance of detection.
Furthermore the bottom of the feed bin is pyramidal structure.
Further, the radar level gauge is offset at the top of feed bin.
Preferably, the Direct Travel executing agency include can horizontal flexible girt back and forth, the one of the girt
End is fixedly connected with radar level gauge, and drives radar level gauge to be rotated around fixed pivot.
Beneficial effect：Compared with prior art, the present invention has following remarkable advantage：The present invention performs machine using Direct Travel
Structure drives radar level gauge rotation, while controller is according to the material position distance signal of radar level gauge and Direct Travel executing agency
Level performs stroke, obtains the optimum tilt angle of radar level gauge, and according to the true material of optimum tilt angle amendment feed bin
Place value so that radar level gauge avoid storage hopper center charging aperture install and measure with cone section bin-level when, can carry significantly
High measurement accuracy.
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the present invention.
Embodiment
Technical scheme is described further below in conjunction with the accompanying drawings.
As shown in Fig. 2 a kind of detection means of adjust automatically radar level gauge setting angle of the present invention, including radar material position
Meter 2, Direct Travel executing agency 3 and controller 4.Feed bin 1 includes the cylindrical structure of upper semisection and the conical structure of lower semisection.
Radar level gauge 2 is located at the top of feed bin 1, and biases and set, and avoids the charging hole site of feed bin center.Direct Travel executing agency 3
Including can horizontal flexible girt back and forth, one end of the girt is fixedly connected with radar level gauge 2, and drives radar
Level-sensing device 2 rotates around fixed pivot.Above-mentioned Direct Travel executing agency 3 and radar level gauge 2 are connected with controller 4 respectively, its
Level is performed stroke by the material position distance signal transmission of detection to controller 4, Direct Travel executing agency 3 by middle radar level gauge 2
Signal is transmitted to controller 4.
Wherein, Direct Travel executing agency 3 is K apart from the vertical range of fixed pivot, can use K=100mm.The Direct Travel is held
The horizontal stroke that performs of row mechanism 3 is S, and the rotation angle of inclination of radar level gauge 2 is α, wherein
Under the hole capital after selling all securities state of feed bin 1, radar level gauge 2 is under the driving of Direct Travel executing agency 3, and slowly rotation from vertical direction, it revolves
Turn tilt angle alpha to incrementally increase, radar level gauge detection material position distance L first incrementally increase, after progressively reduce.And material position distance
It is best angle that L changes flex point rotates tilt angle alpha when occurring, and material position distance L change flex point occurs twice in the present invention,
Optimum angle alpha is corresponded to respectively1And α2, in radar level gauge installs rotary course, rotation angle of inclination that controller detects
α1≤α≤α2When, it is suitable setting angle.
The present invention corrects the controlling level H in material in the rotation tilt angle alpha automatically captured according to controller, wherein
The present invention drives radar level gauge rotation using Direct Travel executing agency, while controller is according to radar level gauge
Material position distance signal and the horizontal of Direct Travel executing agency perform stroke, obtain the optimum tilt angle of radar level gauge, and root
According to the true material position value of optimum tilt angle amendment feed bin so that radar level gauge is installed and surveyed avoiding storage hopper center charging aperture
When amount is with cone section bin-level, measurement accuracy is greatly improved.
