[0024] Example

[0025] like Figure 1 - Figure 7 As shown, this embodiment proposes a signal acquisition device for a base station communication equipment test device, which includes a base 1. The top of the base 1 is provided with a collection mechanism 6 for collecting signals. The top of the base 1 is rotatably connected to an angle mechanism 3 for adjusting the steering angle of the collection mechanism 6. The top of the collection mechanism 6 is provided with a pitch mechanism 5 for adjusting the pitch angle of the collection mechanism 6. The outside of the collection mechanism 6 is provided with a protective mechanism 2 for performing a protective function. A linkage mechanism 4 is provided between the angle mechanism 3 and the protective mechanism 2. The angle mechanism 3 drives the protective mechanism 2 to open and close through the linkage mechanism 4.

[0026] In this embodiment, the angle mechanism 3 includes a first limiting shaft 31, the top of the base 1 is fixedly connected to the first limiting shaft 31, the top of the first limiting shaft 31 is rotatably connected to the first gear 32, the top of the first gear 32 is fixedly connected to the turntable 33, and a mounting bracket 34 is provided on one side of the turntable 33. The mounting bracket 34 is fixedly connected to the base 1, and an angle motor 35 is installed on the mounting bracket 34. The motor shaft of the angle motor 35 is fixedly connected to a second gear 36, and the second gear 36 engages with the first gear 32. The angle motor 35 drives the turntable 33 around the first limiting shaft through the second gear 36 and the first gear 32. The shaft 31 rotates, and a support frame 37 is fixedly connected to the turntable 33 in an offset manner. A top fork 39 in the shape of a "凵" is welded to the top of the support frame 37, and a control box 38 is provided at the bottom end of the support frame 37. The interior of the control box 38 is used for electronic components. When it is necessary to adjust the orientation angle of the collection mechanism 6, the angle motor 35 is first started. The angle motor 35 drives the second gear 36 to rotate, and the second gear 36 engages the first gear 32. Then, the turntable 33 rotates around the first limit axis 31 at the top of the base 1. The turntable 33 drives the mounting bracket 34 and the top fork 39 to rotate, thereby adjusting the horizontal angle of the collection mechanism 6.

[0027] In this embodiment, the pitch mechanism 5 includes a mounting rod 51, and a mounting rod 51 is provided at the top of the mounting bracket 34. A second limiting shaft 58 is fixedly connected to the mounting rod 51, and the second limiting shaft 58 is rotatably connected to the top fork 39. The mounting rod 51 is rotatably connected to the top fork 39 through the second limiting shaft 58. A limiting slide 52 is provided on the mounting rod 51, and a slider 53 is slidably connected inside the limiting slide 52. A stroke motor 54 is installed at one end of the mounting rod 51, and a lead screw 55 is fixedly connected to the motor shaft of the stroke motor 54. The lead screw 55 is rotatably connected to the mounting rod 51, and the lead screw 55 is threadedly connected to the slider 53. An extension bracket 56 is welded to the mounting bracket 34, and a second hydraulic cylinder 57 is installed between the extension bracket 56 and the slider 53; then it is necessary to adjust the pitch angle of the acquisition mechanism 6, Then the second hydraulic cylinder 57 is started, and the second hydraulic cylinder 57 drives the mounting rod 51 through the slider 53, so that the mounting rod 51 rotates around the second limit axis 58. Then the angle between the mounting rod 51 and the mounting bracket 34 changes, and the corresponding pitch angle of the acquisition mechanism 6 changes. Through the adjustment of the angle mechanism 3 and the pitch mechanism 5, the acquisition mechanism 6 can quickly find the signal to be collected, and the collection and capture is faster. When the second hydraulic cylinder 57 is fixed, the stroke motor 54 is started, and the stroke motor 54 drives the screw 55 to rotate, and the screw 55 drives the slider 53 to move inside the limit slide groove 52, so that the pitch angle of the acquisition mechanism 6 can be further adjusted, and this adjustment is more precise, which is convenient for detailed fine-tuning and alignment after the acquisition mechanism 6 finds the approximate signal.

[0028] In this embodiment, the collection mechanism 6 includes an antenna patch 61. A plurality of antenna patches 61 are provided at one end of the mounting rod 51 facing away from the stroke motor 54. The antenna patches 61 are in the shape of fan-shaped arc pieces. One of the antenna patches 61 farthest from the stroke motor 54 is fixedly connected to the mounting rod 51, and the remaining antenna patches 61 are rotatably connected to the mounting rod 51. A second shaft sleeve 63 is fixedly connected to the other antenna patch 61 closest to the stroke motor 54. The second shaft sleeve 63 is rotatably connected to the mounting rod 51. One end of the second shaft sleeve 63 is fixedly connected to a worm gear 64. A protective shell 67 is fixedly connected to the mounting rod 51. The worm gear 64 is located inside the protective shell 67. A transceiver motor 65 is installed on the top of the protective shell 67. A worm 66 is fixedly connected to the motor shaft of the transceiver motor 65. The worm 66 is rotatably connected to the protective shell 67, and the worm 66 and the worm gear 64 are engaged. The outer edge size of the piece 61 increases successively, and a fourth limiting strip 62 is provided on both sides of the antenna patch 61; the antenna component for collecting signals is composed of multiple antenna patches 61 with successively increasing outer edge groove sizes. After the multiple antenna patches 61 are unfolded, the receiving area increases, the collection is more sufficient, and the effect is better. When encountering special weather, in order to reduce the impact of the external environment on the antenna patch 61, the receiving and discharging motor 65 can be started, and the receiving and discharging motor 65 drives the worm 66 to rotate, and the worm 66 engages the worm gear 64. The worm gear 64 drives the corresponding antenna patch 61 to rotate around the mounting rod 51 through the second shaft sleeve 63. The antenna patch 61 drives another adjacent antenna patch 61 to move through the fourth limiting strip 62. In this way, the multiple antenna patches 61 are finally folded together, thereby greatly reducing the unfolded area, reducing the resistance to wind, and facilitating storage.

[0029] In this embodiment, the protective mechanism 2 includes a track ring 21, a track ring 21 is provided at the top of the base 1, and a first protective cover 22 and a second protective cover 23 are provided on the track ring 21. The first protective cover 22 and the second protective cover 23 are connected to the track ring 21 by rollers. The top of the second protective cover 23 of the first protective cover 22 is semicircular, and the outer dimensions of the first protective cover 22 are slightly larger than the second protective cover 23. The first protective cover 22 and the second protective cover 23 are unfolded to protect the angle mechanism 3, the linkage mechanism 4, the pitch mechanism 5 and the collection mechanism 6. A first limit strip 24 is welded on one side of the first protective cover 22, and a third limit strip 26 is welded on the side of the second protective cover 23 close to the first limit strip 24, and a second limit strip 25 is welded on the other side of the second protective cover 23; after the antenna patch 61 is folded, the angle motor 35 rotates the turntable 33 to a suitable position, at which time it just docks with the block 45 is at the top position of the matching slot block 47, the first hydraulic cylinder 46 is started, driving the deflection frame 44 to deflect the angle around the connecting shaft 42, so that the docking block 45 is engaged with the notch position of the matching slot block 47, and the second protective cover 23 is temporarily connected together through the docking block 45 and the matching slot block 47. While the turntable 33 continues to rotate, the second protective cover 23 also rotates. The second protective cover 23 rotates on the track ring 21 through components such as rollers, thereby facilitating the sharing of a power output to drive the protective mechanism 2 to deploy or protect, reducing redundant power settings; when collecting signals and after deploying the protective cover, the first hydraulic cylinder 46 can be started to disengage the docking block 45 from the matching slot block 47, so that the turntable 33 no longer drives the second protective cover 23 to move during rotation. At this time, the load of the angle motor 35 is reduced, and the angle motor 35 has more power to adjust the acquisition mechanism 6, making it easier to use.

[0030] In this embodiment, the linkage mechanism 4 includes a limiting protrusion 41, a plurality of limiting protrusions 41 are welded on the inner wall of the second protective cover 23, a connecting shaft 42 is rotatably connected to the plurality of limiting protrusions 41, a first shaft sleeve 43 is rotatably connected to the connecting shaft 42, a deflection frame 44 is fixedly connected to the first shaft sleeve 43, the deflection frame 44 is in the shape of a triangular fork, a U-shaped docking block 45 is welded to one end of the deflection frame 44, a matching groove block 47 is fixedly connected to the turntable 33, the docking block 45 and the matching groove block 47 are used in conjunction with each other, and a first hydraulic cylinder 46 is installed between the inner wall of the second protective cover 23 and the deflection frame 44; a component for protecting the entire device It consists of a first protective cover 22 and a second protective cover 23. When the collection mechanism 6 is in operation, the first protective cover 22 and the second protective cover 23 overlap and fold together. When protection is needed, the linkage mechanism 4 starts to connect to the angle mechanism 3, driving the second protective cover 23 to move on the track ring 21. After that, the second limit bar 25 on the second protective cover 23 contacts the first limit bar 24, thereby driving the first protective cover 22 to move. At this time, the third limit bar 26 is already inside the first protective cover 22. Then the first protective cover 22 and the second protective cover 23 are combined into a relatively safe enclosed space, isolating the outside world and providing sufficient protection for the device.

[0031] When the present invention is in use, when it is necessary to adjust the orientation angle of the collection mechanism 6, the angle motor 35 is first started, and the angle motor 35 drives the second gear 36 to rotate, and the second gear 36 engages the first gear 32, so that the turntable 33 rotates around the first limit axis 31 at the top of the base 1, and the turntable 33 drives the mounting bracket 34 and the top fork 39 to rotate the angle, so that the horizontal angle of the collection mechanism 6 can be adjusted; then, if it is necessary to adjust the pitch angle of the collection mechanism 6, the second hydraulic cylinder 57 is directly started, and the second hydraulic cylinder 57 drives the mounting rod 51 through the slider 53, so that the mounting rod 51 rotates the angle around the second limit axis 58, then the angle between the mounting rod 51 and the mounting bracket 34 changes, and the corresponding pitch angle of the collection mechanism 6 changes, and the angle motor 35 is used to adjust the pitch angle of the collection mechanism 6. By adjusting the structure 3 and the pitch mechanism 5, the acquisition mechanism 6 can quickly find the signal to be collected, and the collection and capture is faster. When the second hydraulic cylinder 57 is fixed, the stroke motor 54 is started, and the stroke motor 54 drives the screw 55 to rotate, and the screw 55 drives the slider 53 to move inside the limiting slide 52, so that the pitch angle of the acquisition mechanism 6 can be further adjusted, and this adjustment is more precise, which is convenient for detailed fine-tuning and alignment after the acquisition mechanism 6 finds the approximate signal; the antenna component for collecting signals is composed of a plurality of antenna patches 61 with increasing outer edge groove sizes. After the plurality of antenna patches 61 are unfolded, the receiving area increases, the collection is more sufficient, and the effect is better. In case of special weather, in order to reduce the impact of the external environment on the antenna patches, When the antenna patch 61 is affected, the retractable motor 65 can be started, and the retractable motor 65 drives the worm 66 to rotate, and the worm 66 engages the worm gear 64. The worm gear 64 drives the corresponding antenna patch 61 to rotate around the mounting rod 51 through the second shaft sleeve 63. The antenna patch 61 drives another antenna patch 61 close to it to move through the fourth limit strip 62. In this way, multiple antenna patches 61 are folded together, thereby greatly reducing the unfolded area, reducing the resistance to wind, and facilitating storage; after the antenna patch 61 is folded, the angle motor 35 rotates the turntable 33 to a suitable position. At this time, the docking block 45 is just at the top position of the matching slot block 47, and the first hydraulic cylinder 46 is started, driving the deflection frame 44 to deflect the angle around the connecting shaft 42. The docking block 45 is engaged with the notch position of the matching groove block 47, and the second protective cover 23 is temporarily connected together through the docking block 45 and the matching groove block 47. When the turntable 33 continues to rotate, the second protective cover 23 also rotates accordingly. The second protective cover 23 rotates on the track ring 21 through components such as rollers, thereby facilitating the sharing of a power output to drive the protective mechanism 2 to deploy or protect, thereby reducing redundant power settings. When collecting signals and after the protective cover is deployed, the first hydraulic cylinder 46 can be started to disengage the docking block 45 from the matching groove block 47, so that the turntable 33 no longer drives the second protective cover 23 to move during rotation. At this time, the load on the angle motor 35 is reduced, and the angle motor 35 has more power to adjust the acquisition mechanism 6, making it easier to use.The protective assembly for the entire device consists of a first protective cover 22 and a second protective cover 23. When the collection mechanism 6 is operating, the first and second protective covers 22 and 23 overlap and fold together. When protection is required, the linkage mechanism 4 activates and connects to the angle mechanism 3, driving the second protective cover 23 to move on the track ring 21. The second limiting bar 25 on the second protective cover 23 then contacts the first limiting bar 24, thereby driving the first protective cover 22 to move. At this point, the third limiting bar 26 is already inside the first protective cover 22. The first and second protective covers 22 and 23 combine to form a relatively safe enclosed space, isolating the device from the outside world and providing sufficient protection.
