The spring 36 is movably sleeved on the sliding vertical rod 34, the bottom end of the reset spring 36 is fixedly connected to the L-shaped mounting plate 32, and the bottom end of the adjacent sliding vertical rod 34 is fixedly sleeved with a lifting horizontal plate 37, the lifting horizontal plate 37 is slidably connected to the L-shaped mounting plate 32, the middle part of the lifting horizontal plate 37 is fixedly plugged with a vertical guide rod 311, and the middle part of the L-shaped mounting plate 32 is penetrated with a vertical guide hole 312, the vertical guide rod 311 is slidably inserted in the vertical guide hole 312, and the vertical guide rod 311 and the vertical guide hole 312 are used in combination to adjust the lifting The movement and adjustment of the horizontal plate 37 plays a role of limiting and guiding, and a rain collecting frame 38 used in conjunction with it is integrally formed on one side of the lifting horizontal plate 37.

It is connected to an L-shaped stabilizing rod 39 distributed in an array, the ends of the L-shaped stabilizing rod 39 are fixedly connected to the anti-skid oblique rods 310 distributed in an array, and the angle between the anti-skid oblique rods 310 on both sides of the transfer base plate 11 is an obtuse angle.

[0029] By adopting the above technical scheme, during the test, if it rains, rainwater will gradually flow into the rain collecting frame 38, which can further gradually increase the deadweight of the test turntable, thereby gradually improving the stability of the test turntable, and thus ensuring the stable test of the satellite communication antenna. In addition, with the introduction of rainwater, the rain collecting frame 38 will be driven to move downward gradually, thereby driving the lifting horizontal plate 37, the L-shaped stabilizing rod 39 and the limiting side rod 61 to move downward gradually, thereby driving the sliding vertical rod 34, the fixing ring 35, the anti-slip diagonal rod 310, the connecting sleeve rod 62 and the limiting rubber sleeve 63 to move downward gradually and squeeze the reset spring 36. When an appropriate amount of rainwater is received in the rain collecting frame 38, the anti-slip diagonal rod 310 will contact the ground, and the limiting rubber sleeve 63 will contact the directional roller 14, thereby further improving the stability of the test turntable, and thus further ensuring the stable test of the satellite communication antenna.

[0030] The auxiliary mechanism 4 includes a mounting rotating rod 41, a symmetrically distributed rotating socket 315 is opened on the circular mounting frame 33, and the mounting rotating rod 41 is rotatably inserted in the rotating socket 315, the outer side of the mounting rotating rod 41 is rotatably sleeved with a shielding rotating plate 42, and the shielding rotating plate 42 is rotatably clamped in the circular mounting frame 33, and the top of the opposite end of the shielding rotating plate 42 is opened with a mounting sink 43, and the mounting sink 43 is detachably provided with a rain absorbing sponge 44, and the clamping mechanism 5 includes a mounting rotating shaft 51, and the mounting rotating shaft 5 The mounting shaft 51 is fixedly mounted on the shielding rotating plate 42, and the top end of the mounting shaft 51 is rotatably sleeved with a rotating collar 52, the bottom end of the rotating collar 52 is fixedly mounted with a reset torsion spring 53, and the reset torsion spring 53 is movably sleeved on the mounting shaft 51, the bottom end of the reset torsion spring 53 is fixedly connected to the shielding rotating plate 42, and the rotating collar 52 is integrally formed with a Z-shaped clamping rod 54, the bottom end of the Z-shaped clamping rod 54 is slidably fitted with the shielding rotating plate 42, and the Z-shaped clamping rod 54 can fit with the top end of the rain absorbing sponge 44.

[0031] By adopting the above technical solution, when in use, if it rains, rainwater will drip onto the rain absorbing sponge 44, and as the rainwater in the rain absorbing sponge 44 is absorbed, its weight will gradually increase, thereby driving the shielding rotating plate 42 to rotate, and then the rainwater can gradually flow into the rain collecting frame 38, and when the test is completed, the rainwater collected in the rain collecting frame 38 can be discharged, and at this time the reset spring 36 will drive the rain collecting frame 38 to move upward, thereby separating the anti-skid inclined rod 310 from the ground, and separating the limiting rubber sleeve 63 from the directional roller 14, and when the weather is clear, the rainwater in the rain absorbing sponge 44 will be gradually evaporated, so that the shielding The baffle plate 42 automatically reverses and resets, thereby sealing the circular mounting frame 33, thereby preventing foreign matter from entering the rain collecting frame 38. In addition, when the rain-absorbing sponge 44 needs to be replaced, the rotating ring 52 needs to be rotated, thereby driving the Z-shaped clamping rod 54 to rotate and twisting the reset torsion spring 53. When the Z-shaped clamping rod 54 rotates ninety degrees, the rotating ring 52 is stopped and the rain-absorbing sponge 44 to be replaced is taken out for replacement, and then the rotating ring 52 is loosened. At this time, the reset torsion spring 53 will drive the Z-shaped clamping rod 54 to reset through the rotating ring 52, thereby the replaced rain-absorbing sponge 44 can be conveniently fixed.

[0032] Working principle: When in use, fix the satellite communication antenna on the antenna mounting plate 217, then push the antenna mounting plate 217 and use the directional roller 14 and the self-locking universal wheel 16 to push the test turntable to a suitable position outdoors and self-lock the self-locking universal wheel 16, then start the multi-stage electric push rod 23, the first motor 211 and the second motor 213, so that the driving rack 25 can be driven to move back and forth through the driving push plate 24, and then the first gear 26 can be driven to rotate back and forth, and further the L-shaped rotating seat 27 can be driven to rotate in the horizontal direction through the second rotating rod 22, and the first The motor 211 will drive the third gear 212 to rotate, thereby driving the second gear 29 to rotate, and then driving the mounting swivel 210 to rotate in the vertical direction through the third rotating rod 28. In addition, the second motor 213 will drive the side gear 214 to rotate, thereby driving the bevel gear 216 to rotate, and then driving the connecting rotating rod 215 to rotate in the vertical direction, and further enabling the antenna mounting plate 217 to perform three-dimensional rotation adjustment, thereby driving the satellite communication antenna to perform three-dimensional rotation adjustment, and then realizing the multi-angle adjustment test of the satellite communication antenna, further effectively improving the test effect;

[0033] During the test, if it rains, rain will drip onto the rain absorbing sponge 44. As the rain absorbing sponge 44 absorbs rain, its weight will gradually increase, thereby driving the shielding rotating plate 42 to rotate, and then the rain can gradually flow into the rain receiving frame 38, further gradually increasing the deadweight of the test turntable, thereby gradually improving the stability of the test turntable, and thus ensuring the stable test of the satellite communication antenna. In addition, as the rain is introduced, the rain receiving frame 38 will be driven to move downward gradually, thereby bringing The movable lifting horizontal plate 37, the L-shaped stabilizing rod 39 and the limiting side rod 61 are gradually moved downward, thereby driving the sliding vertical rod 34, the fixing ring 35, the anti-skid diagonal rod 310, the connecting rod 62 and the limiting rubber sleeve 63 to gradually move downward and squeeze the reset spring 36. When a proper amount of rainwater is received in the rain receiving frame 38, the anti-skid diagonal rod 310 will contact the ground, and the limiting rubber sleeve 63 will contact the directional roller 14, thereby further improving the stability of the test turntable, thereby further ensuring the stable test of the satellite communication antenna;

[0034] When the test is completed, the rainwater collected in the rain collecting frame 38 can be discharged. At this time, the reset spring 36 will drive the rain collecting frame 38 to move upward, so that the anti-skid inclined rod 310 can be separated from the ground, and the limiting rubber sleeve 63 can be separated from the directional roller 14. In addition, when the weather is clear, the rainwater in the rain absorbing sponge 44 will be gradually evaporated, so that the shielding rotating plate 42 can be automatically reversed and reset, and then the circular mounting frame 33 can be blocked, so as to prevent foreign matter from entering the rain collecting frame 38. In addition, when the rain absorbing sponge 44 needs to be replaced, the rotating ring 52 needs to be rotated, so as to drive the Z-type clamping rod 54 to rotate and twist the reset torsion spring 53. When the Z-type clamping rod 54 rotates ninety degrees, the rotating ring 52 is stopped and the rain absorbing sponge 44 to be replaced is taken out for replacement. Then the rotating ring 52 is loosened. At this time, the reset torsion spring 53 will drive the Z-type clamping rod 54 to reset through the rotating ring 52, so that the replaced rain absorbing sponge 44 can be conveniently fixed.
