[0024] See also Figure 1-Figure 4 As shown, the present invention is a carrier phase detection device for a satellite positioning system, comprising a detection box 1 and a box cover 2, wherein a carrier phase differential measuring instrument 7 and a power supply 8 are fixedly arranged inside the detection box 1, a charging port 101 is arranged at the front end of the detection box 1, an operating part 102 is arranged at the upper end of the detection box 1, a receiving groove 104 is arranged at the upper end of the detection box 1, a first mounting rod 3 and a second mounting rod 4 are adapted to be installed in the receiving groove 104, a communication antenna 301 is arranged on the first mounting rod 3, and a detection probe 401 is arranged on the second mounting rod 4, a group of adjustment components 5 are symmetrically arranged on both sides of the detection box 1, a transmission component 6 is arranged in the middle of the adjustment component 5, and the transmission component 6 is simultaneously transmitted and matched with the adjustment components 5 at both ends.

[0025] Specifically, the carrier phase differential measuring instrument 7 is a device that can process the differential method of the carrier phase observations of two measuring stations in real time, thereby obtaining high-precision positioning. Its principle is that the base station receiver is set up on a reference point with known or unknown coordinates, continuously receives all visible GNSS (Global Navigation Satellite System) satellite signals, and sends the data such as the coordinates of the measuring station, pseudo-range observations, carrier phase observations, satellite tracking status and receiver working status to the mobile station through a wireless data link. While receiving the data from the base station, the mobile station synchronously observes and collects the GNSS satellite carrier phase data, solves the carrier phase integer ambiguity through differential processing within the system, and finally obtains the plane coordinates and elevation of the mobile station based on the correlation between the mobile station and the base station. Among them, the communication antenna 301 on the first mounting pole 3 is used to realize the wireless communication transmission of the detection data, and the detection probe 401 on the second mounting pole 4 is used to realize the collection of carrier phase data.

[0026] like Figure 5-Figure 8 As shown, the adjustment assembly 5 includes a main body 51, an upper rotating part 52, a lower rotating part 53 and a transmission shaft 56. The upper rotating part 52 and the lower rotating part 53 are rotatably mounted on the upper and lower ends of the main body 51 respectively. An upper shaft sleeve 521 is fixedly penetrated in the upper rotating part 52, and a lower shaft sleeve 531 is fixedly penetrated in the lower rotating part 53. An adjustment rod 54 is coaxially penetrated inside the upper shaft sleeve 521 and the lower shaft sleeve 531. The adjustment rod 54 is rotatably matched with the upper shaft sleeve 521, and the adjustment rod 54 is fixedly connected with the lower shaft sleeve 531. The upper end of the detection box 1 is penetrated by There is a limiting groove 103, the top of the adjusting rod 54 passes through the limiting groove 103, the bottom ends of the first mounting rod 3 and the second mounting rod 4 are respectively threadedly connected with the corresponding top ends of the adjusting rod 54, the transmission shaft 56 is horizontally rotatably installed inside the main body 51, and the end of the transmission shaft 56 close to the adjusting rod 54 is sleeved with an adjusting bevel gear 561, the bottom end of the upper rotating part 52 is provided with an upper bevel gear ring 522, and the top end of the lower rotating part 53 is provided with a lower bevel gear ring 532, and the adjusting bevel gear 561 is meshed with the upper bevel gear ring 522 and the lower bevel gear ring 532 at the same time.

[0027] Specifically, by setting the adjustment component 5, when the main body 51 undergoes axial rotation, since the adjustment rod 54 is arranged through the upper sleeve 521 and the lower sleeve 531, the main body 51 will drive the upper rotating part 52 and the lower rotating part 53 to deflect synchronously, thereby causing the adjustment rod 54 to deflect, so as to achieve the swing angle adjustment of the communication antenna 301 and the detection probe 401. When the transmission shaft 56 undergoes axial rotation, since the adjustment bevel gear 561 is meshed with the upper bevel gear ring 522 and the lower bevel gear ring 532 at the same time, the transmission shaft 56 will drive the upper rotating part 52 and the lower rotating part 53 to rotate simultaneously, wherein the lower rotating part 53 will drive the adjustment rod 54 to rotate synchronously, and the upper rotating part 52 will rotate in the opposite direction outside the adjustment rod 54, so as to impose axial constraints on the rotation process of the adjustment rod 54, so that it can be kept rotating in the upper sleeve 521 and the lower sleeve 531 to improve the balance stability, thereby achieving the rotation angle adjustment of the communication antenna 301 and the detection probe 401. The swinging process and the rotation process of the adjustment rod 54 are independently controlled by the main body 51 and the transmission shaft 56 respectively. The two adjustment processes are carried out independently of each other and do not interfere with each other. They can effectively improve the communication receiving range of the communication antenna 301 and the detection range of the detection probe 401, which is beneficial to the carrier phase detection process.

[0028] like Figure 6 and Figure 7 As shown, a support seat 55 is provided on the outside of the main body 51, and the support seat 55 is fixedly connected to the detection box 1. The main body 51 is rotatably installed in the support seat 55. Rotation grooves 511 are provided at the upper and lower ends of the main body 51. The upper rotating part 52 and the lower rotating part 53 are respectively rotatably installed in the corresponding rotation grooves 511. A clearance groove 512 is provided inside the main body 51, and the adjusting bevel gear 561 is provided in the clearance groove 512. The first bevel gear 513 is sleeved on one end of the main body 51 close to the transmission assembly 6.

[0029] Specifically, the support seat 55 can provide rotation support for the main body 51, so that the main body 51 always maintains a horizontal state during the rotation along the axial direction; the upper rotating part 52 and the lower rotating part 53 are rotatably installed in the rotating groove 511, so that the upper rotating part 52 and the lower rotating part 53 can realize self-rotation while also being able to swing synchronously with the main body 51; the yield groove 512 can provide sufficient activity space for the adjusting bevel gear 561 to engage with the upper bevel gear ring 522 and the lower bevel gear ring 532.

[0030] like Figure 6 and Figure 8 As shown, a second bevel gear 562 is sleeved on one end of the transmission shaft 56 close to the transmission assembly 6, a limiting ring protrusion 563 is extended on the outer side of the transmission shaft 56, a groove is provided inside the main body 51, and the limiting ring protrusion 563 is adapted to be rotatably installed in the groove.

[0031] Specifically, the function of the limiting ring protrusion 563 is to impose axial displacement constraints on the transmission shaft 56, so that the transmission shaft 56 will always remain in the main body 51 when it rotates, and will not deviate to the left or right, thereby ensuring the meshing stability of the adjusting bevel gears 561 and the second bevel gear 562 at its two ends.

[0032] like Figure 5 As shown, the transmission assembly 6 includes a first motor 61 and a second motor 62. The output end of the first motor 61 is connected to a swing bevel gear 611, and the swing bevel gear 611 is simultaneously meshed with the first bevel gears 513 at both ends. The output end of the second motor 62 is connected to a rotating bevel gear 621, and the rotating bevel gear 621 is simultaneously meshed with the second bevel gears 562 at both ends.

[0033] Specifically, by setting up the transmission component 6, when the first motor 61 drives the swinging bevel gear 611 to rotate, the swinging bevel gear 611 will drive the main body 51 at both ends to rotate simultaneously through the first bevel gear 513, thereby realizing the synchronous swing adjustment of the communication antenna 301 at both ends and the detection probe 401. Similarly, when the second motor 62 drives the rotating bevel gear 621 to rotate, the rotating bevel gear 621 will drive the transmission shaft 56 at both ends to rotate simultaneously through the second bevel gear 562, thereby realizing the synchronous rotation adjustment of the communication antenna 301 at both ends and the detection probe 401.

[0034] It should be noted that in order to ensure the independence of the adjustment and control processes, the first motor 61 is fixed on one side of the detection box 1, and the second motor 62 is fixed on the top of the detection box 1. The swinging bevel gear 611 and the rotating bevel gear 621 are perpendicular to each other and are respectively meshed with the first bevel gear 513 and the second bevel gear 562 in different planes, so that the swinging process and the rotating process can be independently controlled.

[0035] like Figure 6 and Figure 7 As shown, bearings 57 are sleeved on the outer sides of the upper sleeve 521 and the lower sleeve 531 , and the bearings 57 are rotatably matched with the main body 51 . The bearings 57 can effectively improve the rotation effect between the upper sleeve 521 and the lower sleeve 531 and the main body 51 .

[0036] like Figure 6 As shown, the first mounting rod 3, the second mounting rod 4 and the adjusting rod 54 are all provided with hollow cavities along the axial direction, the communication antenna 301 and the detection probe 401 are respectively connected to one end of the wire, and the other end of the wire passes through the corresponding hollow cavity and is communicatively connected to the carrier phase differential measuring instrument 7.

[0037] Specifically, during the detection process, the wires used for communication and detection will pass through the first mounting rod 3 and the second mounting rod 4 from the inside, respectively, and pass out from the bottom of the corresponding adjustment rod 54, thereby realizing internal routing, making the wire arrangement neat and reasonable, and avoiding the situation where the wires are tangled during the rotation and adjustment of the adjustment rod 54.

[0038] The working principle of the present invention is as follows: Figure 1-Figure 8 As shown, when in use, the first mounting rod 3 and the second mounting rod 4 are respectively screwed into the top of the corresponding adjustment rod 54, wherein the communication antenna 301 on the first mounting rod 3 is used to realize the wireless communication transmission of the detection data, and the detection probe 401 on the second mounting rod 4 is used to realize the acquisition of the carrier phase data. During the detection process, when the first motor 61 drives the swing bevel gear 611 to rotate, the swing bevel gear 611 will drive the main body 51 at both ends to rotate simultaneously through the first bevel gear 513. When the main body 51 undergoes axial rotation, since the adjustment rod 54 is set through the upper sleeve 521 and the lower sleeve 531, the main body 51 will drive the upper rotating part 52 and the lower rotating part 53 to deflect synchronously, thereby causing the adjustment rod 54 to deflect, so as to realize the swing angle adjustment of the communication antenna 301 and the detection probe 401. When the second motor 62 drives the rotating bevel gear 621 to rotate, the rotating bevel gear 621 will drive the transmission shafts 56 at both ends to rotate simultaneously through the second bevel gear 562. When the transmission shaft 56 rotates axially, since the adjusting bevel gear 561 is meshed with the upper bevel gear ring 522 and the lower bevel gear ring 532 at the same time, the transmission shaft 56 will drive the upper rotating part 52 and the lower rotating part 53 to rotate simultaneously, wherein the lower rotating part 53 will drive the adjusting rod 54 to rotate synchronously, and the upper rotating part 52 will rotate in the opposite direction on the outside of the adjusting rod 54 to impose axial constraints on the rotation process of the adjusting rod 54, so as to keep it rotating in the upper shaft sleeve 521 and the lower shaft sleeve 531 to improve the balance stability, thereby realizing the rotation angle adjustment of the communication antenna 301 and the detection probe 401. The swinging process and the rotation process of the adjustment rod 54 are independently controlled by the main body 51 and the transmission shaft 56 respectively. The two adjustment processes are carried out independently of each other and do not interfere with each other. They can effectively improve the communication receiving range of the communication antenna 301 and the detection range of the detection probe 401, which is beneficial to the carrier phase detection process.

[0039] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
