Problems solved by technology

[0004] The slope indicator has high requirements on the stability of the beam. The traditional heliport slope indicator sets the beam elevation angle of the equipment by manually adjusting the mechanical locking device. The adjustment process is complicated and the adjustment accuracy is difficult to guarantee.
In addition, in some scenarios, for example, it is necessary to park the helicopter on a temporary take-off and landing platform. The temporary take-off and landing platform generally does not have good stability, and there is a need for quick installation and elevation angle adjustment of the slope indicator. The traditional adjustment method is in After adjusting the beam elevation angle, it will be a fixed beam elevation angle, which is not applicable to temporary take-off and landing platforms

[0061] In a first exemplary embodiment of the present disclosure, a portable self-stabilizing grade indicator is provided.

[0062] figure 1 It is a structural schematic diagram of a portable self-stabilizing gradient indicator according to an embodiment of the present disclosure. figure 2 It is a schematic structural diagram of a bracket assembly according to an embodiment of the present disclosure. image 3 For such figure 1 The portable self-stabilizing grade indicator shown is a view of the box enclosure in the main box from the right side. Figure 4 For such figure 1 The perspective view of the remaining structure of the main case in the portable self-stabilizing grade indicator shown after removing the case shell. Figure 5 For such Figure 4 An exploded view of the structure shown.

[0063] refer to Figure 1-Figure 5 As shown, the portable self-stabilizing gradient indicator of the present disclosure includes: a bracket assembly 200; and a main chassis 100, whi...

[0086] In the second exemplary embodiment of the present disclosure, an elevation angle adjustment method based on any portable self-stabilizing grade indicator mentioned in the present disclosure is provided.

[0087] The elevation adjustment method of the present embodiment includes:

[0088] Step S11: receiving preset state information, the preset state information includes a preset elevation angle;

[0089] For example, in a scene of adjusting the elevation angle of the light beam, the user triggers the elevation angle adjustment mode on the display module 140 through the control button, and sets the working elevation angle of the target (incline adjuster). It is assumed that the status information may include other status information, such as light intensity, flash frequency, etc., in addition to the preset elevation angle.

[0090] In a scene of landing on the temporary lifting center, the wirelessly transmitted preset state information (including the preset elevation a...

[0095] In a third exemplary embodiment of the present disclosure, an application of any portable self-stabilizing gradient indicator mentioned in the present disclosure in a temporary take-off and landing platform is provided, and the temporary take-off and landing platform includes the following platform One: helipad, mobile airport, offshore work platform, roof apron or trailer platform.

[0096] The slope indicator of the present disclosure is suitable for various temporary lifting platforms. For example, when the equipment installation platform is unstable, the main box will tilt with the vibration of the temporary lifting platform. At this time, the inclinometer can monitor the optical structure inside the box. The angle of inclination changes. The control module controls the stepping motor on the angle stage to adjust the elevation angle of the optical structure relative to the bottom surface (or horizontal plane, bottom plate, ground, etc.), thus effectively ensuring tha...

Abstract

The invention discloses a portable self-stabilizing slope indicator, an elevation angle adjusting method and application thereof. The slope indicator comprises: a support assembly; a mainframe box which is detachably connected with the bracket assembly and is used for outputting a three-color light beam to indicate a slope signal, wherein the mainframe box comprises a box body shell and an internal device located in the box body shell, and the internal device comprises: an optical structure used for outputting three-color light beams; an inclinometer which is arranged on the optical structureand used for monitoring the elevation angle of the three-color light beam relative to the ground; an angular position table, wherein the optical structure is arranged on the angular position table, and the angular position table can controllably rotate relative to the elevation angle of the ground; and a control module which is used for controlling the angular position table to rotate according tothe elevation angle, fed back by the inclinometer, of the three-color light beam relative to the ground so as to adjust the three-color light beam to be output at a preset elevation angle. The portable self-stabilizing slope indicator has the advantages of high adjusting precision, high adjusting speed, high reliability and convenience in carrying.

Description

technical field [0001] The disclosure belongs to the field of optics, and relates to a portable self-stabilizing gradient indicator, a method for adjusting an elevation angle and an application thereof. Background technique [0002] The three-color visual approach slope indicator (hereinafter referred to as the slope indicator) is a device that integrates light, mechanics and electricity, and guides the helicopter to return at night or under low visibility conditions. The slope indicator provides the pilot with a relatively stable descent angle light guidance signal relative to the ground level, and guides the helicopter to the sky above the takeoff and landing platform. [0003] The slope indicator can provide the pilot with three slope signals: yellow - above the approach course, green - on the approach course, red - below the approach course. A typical slope indicator beam has a vertical angle of 14°, of which the vertical angle of yellow light is 8°, the vertical angle ...
