The air inlet of the air compressor 17 extends to the outside of the connecting rod 4 through the air inlet pipe. In actual use, the air inlet of the air compressor 17 needs to be connected to an external dehumidifier. The dehumidifier can be a rotary dehumidifier. The model and size of the dehumidifier can be set according to the requirements and are not limited here. A temperature sensor 18 is installed at the air outlet of the air compressor 17.

The inner cavity of the blower plate 6 is connected to the inner cavity of the connecting rod 4 through the inner cavity of the rotating ring 3 and the inner cavity of the hollow partition plate 15.

[0034] As described above, the protective structure allows for compressed air blowing to the outer casing of the Beidou receiver, preventing sand, hail, or rainstorms from directly impacting the casing, reducing the impact force on the casing, and extending its service life. Furthermore, when the electric heating network 16 is working, the blower plate 6 can blow out hot air to melt ice or snow on the surface of the casing, preventing ice and snow from affecting the use of the Beidou receiver.

[0035] In addition, the outer casing is equipped with a rainstorm monitoring sensor and a hail sensor (not shown in the figure). Both the rainstorm monitoring sensor and the hail sensor are existing technologies, and their models and positions can be set according to requirements without limitation. The rainstorm monitoring sensor can be used to monitor rainstorms, and the hail sensor can be used to monitor hail. The controller of this application can determine whether there is rainstorm or hail based on the monitoring results, and then control the operation of the protective structure as needed. The compressed air blown out by the blower plate 6 can blow away or buffer the rainstorm or hail, avoid the rainstorm or hail directly impacting the outer casing, reduce the impact of natural disasters on this application, and facilitate the use of the Beidou receiver.

[0036] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0037] In summary, this application improves upon existing BeiDou receivers by incorporating a triple shock absorption design. This reduces the impact of hydropower station slope vibrations on the receiver's stability, facilitating its operation. Furthermore, during use, the controller of this hydropower station slope monitoring BeiDou receiver can determine the presence of heavy rain or hail based on the monitoring results from the rainstorm and hail sensors. Consequently, it can control the protective structure as needed. When the protective structure is in operation, servo motor 7 drives the blower plate 6 to rotate, as shown in the figure. The air compressor 17 then compresses the incoming outside air and compresses the air... The compressed air is blown into the inner cavity of the connecting rod 4. The compressed air in the inner cavity of the connecting rod 4 enters the blower plate 6 through the hollow partition plate 15, the rotating ring 3 and the hollow rotating shaft 21. The compressed air in the blower plate 6 is sprayed onto the outer shell, blowing away the rain or hail around the outer shell and preventing the rain or hail from directly impacting the outer shell, thus protecting the outer shell. In addition, the temperature sensor 18 monitors the temperature of the compressed air discharged from the air compressor 17. If it is necessary to melt the snow or ice on the outer shell, the controller of this application can control the working frequency of the electric heating network 16 according to the monitoring result of the temperature sensor 18, so that the hot air blown out by the blower plate 6 can melt the snow or ice while reducing the energy consumption of this application.

[0038] Compressed air blown out by the blower plate 6 is used to blow away rain or hail, avoiding direct impact of rain or hail on the outer casing, reducing the impact of natural disasters on this application, and facilitating the use of the Beidou receiver.
