Description

Technical Field

[0001] This utility model relates to the field of meteorological radar testing and calibration technology, and in particular to a tilt adjustment device for millimeter-wave cloud measuring instruments. Background Technology

[0002] Millimeter-wave cloud measuring instruments are meteorological detection devices primarily used for high-precision monitoring of parameters such as cloud structure, particle phase, and liquid water content. Currently, most mainstream millimeter-wave cloud measuring instrument antennas have a non-rotatable structure, pointing perpendicular to the ground upwards. When calibrating a metal sphere, because the antenna is perpendicular to the horizontal ground upwards, the metal sphere can only be suspended directly above the cloud measuring instrument antenna. Since the distance between the metal sphere and the cloud measuring instrument antenna must meet far-field conditions during calibration, the UAV needs to carry the metal sphere to a considerably high position, placing high demands on the UAV's performance. Secondly, the UAV is inevitably within the cloud measuring instrument's signal beam during calibration. To reduce the impact of the UAV's own echo on the calibration results, the connecting rope between the UAV and the metal sphere needs to be at least three times the length of the cloud measuring instrument's distance gauge. A longer connecting rope increases the swing amplitude of the metal sphere in the air due to environmental wind, making it prone to swinging to the edge of the distance gauge or outside the gauge during testing, compromising the accuracy of the calibration results.

[0003] Therefore, this application develops a tilt adjustment device for millimeter-wave cloud measuring instruments to solve the above problems. Utility Model Content

[0004] This invention proposes a tilt adjustment device for millimeter-wave cloud measuring instruments to solve the problem of difficulty in ensuring the accuracy of calibration results in existing systems.

[0006] Furthermore, the first support includes a first rod, a hinge, and a first locking plate. The hinge is used to connect the upper end of the first rod to the connector on the bottom of the millimeter-wave cloud measuring instrument, and the first locking plate is disposed at the lower end of the first rod.

[0007] Furthermore, the second support includes a second rod and a second locking plate, with the second locking plate disposed at the lower end of the second rod.

[0023] like Figure 1 and Figure 2 As shown, a tilt adjustment device for a millimeter-wave cloud measuring instrument includes: The base includes a fixed base 2 and a rotating base 4. One side of the rotating base 4 is rotatably connected to the fixed base 2. The rotating base 4 is used to detachably mount the bottom of the millimeter-wave cloud measuring instrument. The base slot 8 is horizontally fixed to one side of the fixed base 2, and a row of slot openings 9 are distributed at intervals on the base slot 8. The first support has an upper end that is rotatably connected to one side of the rotating base 4, and the lower end of the first support is provided with a first plug-in part that can be engaged with each slot 9. The second support has a second plug-in part at its lower end that engages with each slot 9, and the upper end of the second support is used to connect to the detachable support of the millimeter-wave cloud measuring instrument 14.

[0024] In one embodiment, the first support includes a first rod 7, a second hinge 6, and a first locking plate 710. The hinge is used to connect one end of the first rod 7 to a connector on the bottom of the millimeter-wave cloud measuring instrument, and the first locking plate 710 is disposed at the lower end of the first rod 7.

[0025] In one embodiment, the second support includes a second rod 11 and a second locking plate, with the second locking plate disposed at the lower end of the second rod 11.

[0026] In one embodiment, a row of through holes is provided on each side of the second rod, the through holes being used to connect with the fixture 13 on the millimeter-wave cloud measuring instrument 14 via pins. The fixture 13 is provided with a hinge structure, the hinge structure being hinged to the upper end of the second rod 11. The second rod 11 is supported and connected to the fixture 13 on the millimeter-wave cloud measuring instrument 14.

[0027] In one embodiment, the second rod 11 is a telescopic rod.

[0028] In one embodiment, a first angular bracket 1 and a second angular bracket 3 are respectively provided on both sides of the fixed base 2. The two angular brackets are respectively horizontally arranged on both sides of the fixed base 2. The fixed base 2 and the first angular bracket 1 and the second angular bracket 3 are all provided with fixing bolts for fixing, such as fixing bolt 12.

[0029] In one embodiment, one end of the base slot 8 extends to the bottom of the fixed base 2 and is connected to the bottom of the fixed base 2, and the other end of the base slot 8 is connected to a fixing rod 10, which is arranged longitudinally and has fixing bolts for fixing.

[0030] In one embodiment, a reinforcing rod is provided longitudinally at the bottom of the fixed base 2. The reinforcing rod connects the bottom of the fixed base 2 with the base slot 8, and a fixing bolt for fixing is provided on the reinforcing rod.

[0031] In one embodiment, the fixed base 2 and the rotating base 4 are rotatably connected on one side by a first hinge 5, and the fixed base 2 and the rotating base 4 are connected on the other side by a detachable latch.

[0032] The working principle of this utility model is as follows: Secure the upper end of the second support to the fixture 13 using a pin. Manually push the cloud measuring instrument to tilt it, inserting the other end of the second support into the theoretical position in the slot of the device base. Insert the first support into the slot as well, fixing the cloud measuring instrument at a certain tilt angle and maintaining stability. Measure the tilt angle using an angle meter. If the tilt angle does not meet the desired value, adjust the slot position of the support rod to fine-tune the tilt angle of the cloud measuring instrument to the desired value.

[0033] The base replaces the original millimeter-wave cloud measuring instrument base, ensuring the cloud measuring instrument antenna remains vertically upward and allowing the entire instrument to tilt using its hinge structure. Supports extending in the tilting direction are designed to provide sufficient support when the cloud measuring instrument tilts. The first and second angled brackets extending to both sides prevent the cloud measuring instrument from tipping over, improving overall stability. The base slot 8 is used to insert the first and second supports, preventing them from sliding. The first support is installed on the tilting side of the base to distribute the pressure on the second support, improving overall safety. The fixing device 13 is the main stress point when the cloud measuring instrument tilts. It is installed on the tilting side of the cloud measuring instrument chassis, on the same vertical plane as the base slot 8. The upper end of the support rod is fixed by passing a pin through the holes on both the support rod and the fixing device. The fixing device 13 also has a hinge structure, allowing adjustment of the angle between the second support and the cloud measuring instrument chassis after the support rod is fixed. The second support is the main load-bearing component of the device. One end is connected to the fixing device 13 and the other end is inserted into the base slot 8, so that the cloud measuring instrument body, the second support and the base form a stable rigid triangular structure. The rod of the second support is designed with holes for pin fixing, and the bottom end of the second support is designed as a plate to be easily inserted into the slot.

[0034] This invention relates to a tilt adjustment device for a millimeter-wave cloud measuring instrument, which tilts the cloud measuring instrument to form a variable angle with the ground and can maintain a stable tilt for a long time. After the cloud measuring instrument is tilted, the beam no longer points vertically upward. When calibrating the metal ball, the UAV can be placed outside the beam, reducing the required flight altitude of the UAV to meet the far-field conditions, avoiding interference from the UAV's own echo on the test results, and reducing the length of the connecting rope between the metal ball and the UAV, thus greatly reducing the impact of environmental wind on the stability of the metal ball.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
