[0036] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below. In addition, for the purpose of more clearly describing the present invention, parts not connected to the invention will be omitted from the drawings.

[0037] like Figure 1-3 As shown, an automatically installable narrowband antenna satellite targeting device includes: a lower mounting box 100, two upper mounting boxes 200, and a satellite targeting mechanism 300;

[0038] The lower mounting box 100 is equipped with casters at the four corners of its lower end to facilitate manual pushing and transportation;

[0039] The upper mounting box 200 is hinged to both the left and right sides of the upper end of the lower mounting box 100.

[0040] The lower mounting box 100 and the two upper mounting boxes 200 are equipped with a star-aligning mechanism 300.

[0041] like Figure 4 , Figure 5 As shown, a drive motor 110 is fixedly installed at the middle of the upper part of the bottom plate of the lower mounting box 100, and the drive motor 110 is a dual-output shaft motor;

[0042] Both output shafts of the drive motor 110 are fixedly connected to drive rods 111;

[0043] Both drive rods 111 are fixedly equipped with first gears 112 on the side of the front and rear side plates of the lower mounting box 100;

[0044] The two drive rods 111 pass through the side plate of the lower mounting box 100 and are fixedly equipped with engaging gears 113;

[0045] The outer sides of both engaging gears 113 are engaged with second gears 114. That is, when the second gears 114 can rotate normally, the engaging gears 113 can drive the second gears 114 to rotate synchronously. When the second gears 114 cannot rotate, the engaging gears 113 can rotate independently relative to the second gears 114.

[0046] The two second gears 114 are each meshed with a third gear 115 on both the left and right sides, and all four third gears 115 can be rotatably mounted on the front and rear end side plates of the lower mounting box 100.

[0047] A fourth gear 116 is fixedly installed on the side of each of the four third gears 115 away from the drive motor 110;

[0048] The four fourth gears 116 are installed to rotate synchronously with one end of their corresponding first belts 117.

[0049] The other ends of the four first belts 117 are respectively installed to rotate synchronously with their corresponding fifth gears 118.

[0050] Each of the four fifth gears 118 has a round rod fixedly installed in the middle of the side near the drive motor 110 and can be rotatably installed inside the corresponding fixed gear 119.

[0051] The four fixed gears 119 are respectively fixedly installed on the corresponding top plates 121 at the four corners of the upper end of the upper and lower mounting boxes 100;

[0052] A second belt 120 is mounted on the outer side of the four fixed gears 119;

[0053] like Figure 4-6 As shown, the two upper mounting boxes 200 are fixedly provided with first mounting rods 210 on the front and rear sides of the lower end on the side away from each other, and the four first mounting rods 210 can be rotatably installed in the slots opened in their corresponding top plates 121, and the four first mounting rods 210 are fixedly connected to their corresponding fifth gears 118.

[0054] The upper ends of the two upper mounting boxes 200, which are located away from each other, are rotatably equipped with second mounting rods 220, and the front and rear ends of the two second mounting rods 220 are fixedly provided with sixth gears 221.

[0055] The four sixth gears 221 are installed synchronously with their corresponding second belts 120. That is, when the upper mounting box 200 rotates along the first mounting rod 210, the relative position of the sixth gear 221 and the fixed gear 119 changes, causing the sixth gear 221 to rotate in the opposite direction to the rotation direction of the upper mounting box 200, thereby driving the second mounting rod 220 to rotate.

[0056] A support plate 222 is fixedly installed at the lower end of each of the two second mounting rods 220, that is, when the second mounting rod 220 rotates, the support plate 222 will rotate towards the ground.

[0057] like Figure 2 , Figure 7-10 As shown, the satellite tracking mechanism 300 includes: a first fixing plate 310, a second fixing plate 320, a control component 330, a third fixing plate 340, and a communication device 350;

[0058] The first fixing plate 310 is fixedly disposed inside the lower end of the lower mounting box 100;

[0059] A control motor 311 is fixedly installed at the lower middle part of the first fixing plate 310, and the control motor 311 is located at the upper end of the drive motor 110;

[0060] The output end of the control motor 311 passes through the first fixing plate 310 and is fixedly connected to the control rod 312, and the outer side of the control rod 312 is provided with a threaded groove.

[0061] The control rod 312 has a moving groove 313 on both the front and rear sides on the first fixed plate 310;

[0062] Both of the moving slots 313 have abutment members 314 slidably installed on their inner sides, and the upper cross section of the two abutment members 314 is arc-shaped, and the lower end is threaded onto their corresponding rotating rods 315.

[0063] The two rotating rods 315 are provided with threads in opposite directions on their outer sides, and they are respectively rotatably mounted on the first mounting plate 316 fixedly disposed at the lower end of the first fixing plate 310;

[0064] A seventh gear 317 is fixedly installed on the side of both rotating rods 315 away from the control motor 311;

[0065] The outer peripheries of the two seventh gears 317 are respectively installed to rotate synchronously with the upper end of their corresponding third belts 318;

[0066] The lower ends of the two third belts 318 are installed synchronously with their corresponding first gears 112. That is, when the first gear 112 rotates, it will drive the seventh gear 317 and the rotating rod 315 to rotate through the third belts 318. Thus, through the threaded engagement of the rotating rod 315 and the abutment 314, the abutment 314 moves horizontally along the moving groove 313.

[0067] like Figure 9-12 As shown, the second fixing plate 320 is located above the first fixing plate 310 and is fixedly installed inside the lower mounting box 100;

[0068] The first rotating disk 321 is rotatably mounted in the middle of the second fixing plate 320;

[0069] The lower end of the first rotating disk 321 is fixedly provided with an abutment part 322, and the abutment part 322 can abut against the abutment member 314;

[0070] Connecting plates 323 are fixedly installed on both the front and rear sides of the upper end of the first rotating disk 321;

[0071] A control unit 324 is fixedly installed at the upper center of the first rotating disk 321;

[0072] The control unit 324 has a control slot 325 inside, and the control slot 325 has a spline groove inside.

[0073] like Figure 9-13 As shown, a sliding part 331 is fixedly provided at the lower end of the control component 330, and a spline is provided on the outer side of the sliding part 331, which can slide vertically inside the control groove 325.

[0074] The sliding part 331 has a slot inside, and a threaded groove is provided on the inner side of the slot. It can be tightly installed with the thread on the control rod 312. That is, when the sliding part 331 can rotate, the rotation of the control rod 312 will drive the sliding part 331 to rotate synchronously. When the sliding part 331 cannot rotate, the rotation of the control rod 312 will control the sliding part 331 to move vertically.

[0075] The control component 330 is fixedly provided with connecting rods 332 at both its left and right ends;

[0076] Both connecting rods 332 are rotatably mounted to the lower end of the lifting component 333;

[0077] like Figure 9-14 As shown, a second rotating disk 341 is rotatably mounted in the middle of the third fixing plate 340, and the lower end of the second rotating disk 341 is fixedly connected to the upper end of the connecting plate 323, that is, the second rotating disk 341 rotates synchronously with the first rotating disk 321.

[0078] Both ends of the third fixing plate 340 are provided with passage slots 342 for the lifting component 333 to pass through;

[0079] The front ends of both of the aforementioned slots 342 are fixedly provided with second mounting plates 343 on the third fixing plate 340;

[0080] like Figure 9-15 As shown, an antenna 351 is installed on the upper end of the communication device 350;

[0081] The front end of the communication device 350 is fixedly provided with a rotating rod 352, which can be rotatably mounted on the second mounting plate 343;

[0082] The communication device 350 is fixedly provided with lifting rods 353 at both ends, and the two lifting rods 353 are rotatably installed at the upper end of their corresponding lifting components 333.

[0083] Working principle:

[0084] When transporting and installing narrowband communication equipment: the entire equipment is manually moved to the emergency location. Then, the drive motor 110 controls the drive rod 111 to rotate, which in turn controls the engaging gear 113 to drive the second gear 114 to rotate, and subsequently drives the third gear 115, fourth gear 116, first belt 117, and fifth gear 118 to rotate synchronously. This controls the two upper mounting boxes 200 to rotate and unfold in opposite directions. Simultaneously with the unfolding of the two upper mounting boxes 200, the relative position of the sixth gear 221 and the fixed gear 119 changes, causing the sixth gear 221 to rotate in the same direction as the upper mounting box 200. The drive rod 111 rotates in the opposite direction to rotate the second mounting rod 220, thereby controlling the support plate 222 to rotate closer to the ground. Simultaneously, the first gear 112 on the drive rod 111 drives the seventh gear 317 and the rotating rod 315 to rotate via the third belt 318. This, through the threaded engagement of the rotating rod 315 and the abutment member 314, causes the abutment member 314 to move horizontally along the moving groove 313 towards the abutment portion 322 until the support plate 222 abuts against the ground, ensuring the stability of the overall equipment. At this point, the abutment member 314 and the abutment portion 322 are not fully engaged. Subsequently, the control motor 311 drives the control... The control rod 312 rotates, and due to the tight fit between the control rod 312 and the internal slot of the sliding part 331, the rotation of the control rod 312 will drive the sliding part 331 to rotate synchronously. This will drive the first rotating disk 321 to rotate through the control slot 325, and drive the second rotating disk 341 to rotate through the connecting plate 323. This will drive the communication device 350 on the second rotating disk 341 to rotate until the antenna 351 on the communication device 350 rotates to the optimal position. Then, the drive rod 111 is controlled by the drive motor 110 to continue rotating. At this time, because the support plate 222 abuts against the ground, the engaging gear 113 rotates relative to the second gear 114. Simultaneously, the first gear 112 on the drive rod 111 will drive the abutment 314 to move along the moving groove 313 through the above transmission until the abutment 314 abuts against the abutment 322 to limit the abutment 322, thereby ensuring the stability of the azimuth angle. Then, the control rod 312 is controlled to rotate by the control motor 311. Since the abutment 322 cannot rotate, the sliding part 331 will move upward along the control groove 325 through its threaded engagement with the control rod 312, thereby driving the lifting part 333 to move upward, thereby controlling the communication device 350 to rotate along the rotating rod 352 until it rotates to the optimal azimuth.

[0085] When the narrowband communication device is no longer in use: simply reverse the steps above.
