[0030] See also Figure 5 As shown, a signal receiver with a lightning protection structure, the signal receiver mounting assembly 4 is used to install the signal receiver, the top of the fixed base plate 401 is fixedly connected with a threaded column 402, and the external thread of the threaded column 402 is connected with a first adjusting nut 403, the top of the first adjusting nut 403 is provided with an adjusting port 404, and the top of the adjusting port 404 is provided with a second adjusting nut 405, the inner diameter of the adjusting port 404 is larger than the outer diameter of the threaded column 402, and the inner diameter of the adjusting port 404 is smaller than the outer diameter of the first adjusting nut 403, and the outer diameter of the first adjusting nut 403 is consistent with the outer diameter of the second adjusting nut 405, the four corners of the signal receiver base plate 1 can be raised and lowered by screwing the adjusting nuts, so that it is convenient to level the signal receiver base plate 1 after fixing the fixed base plate 401, so that the signal receiver on its top can be horizontally installed and fixed on the ground.

[0031] See also Figure 6As shown, a signal receiver with a lightning protection structure, the switch component 5 is used to switch the second lightning protection shell 304, the switch housing 501 forms a rotating structure with the second lightning protection shell 304 through the rotating shaft 502, and the shape of the switch housing 501 is hemispherical, the clamping block 503 and the bayonet 504 form a clamping structure, and the clamping block 503 and the switch housing 501 are integrated, and the bayonet 504 and the first lightning protection shell 301 are integrated, and the clamping block 503 and the bayonet 504 can be fixed and opened by rotating the switch housing 501, so as to facilitate the fixing or opening of the second lightning protection shell 304, and the shape of the rotating switch housing 501 is also set to be hemispherical, without sharp corners, so as to prevent sharp discharge from causing lightning.

[0032] Working principle: First, when installing the signal receiver, four holes are dug on the ground, and the fixed bottom plate 401 is buried in the holes, and the holes are sealed with concrete, and the fixed bottom plate 401 is fixed at the same time. After being buried and fixed, if the signal receiver bottom plate 1 is not in a horizontal state due to the uneven ground or errors when fixing the fixed bottom plate 401 with concrete, the first adjustment nut 403 and the second adjustment nut 405 can be screwed to adjust the lower or higher corner of the signal receiver bottom plate 1;

[0033] In the spring and summer when there are thunderstorms, in thunderstorm weather, the staff can rotate and close the second lightning protection shell 304, and rotate the switch shell 501 at the same time. The switch shell 501 rotates with the block 503 until the block 503 rotates and snaps into the inside of the bayonet 504 to fix it. At this time, the first lightning protection shell 301 and the second lightning protection shell 304 together form a spherical protective shell. The tip discharge phenomenon refers to the existence of a sharp metal object in space. Due to the concentration of charge on the surface of the tip, the surface area of ​​the tip is very small. Even if the atmospheric electric field is weak, a higher electric field will be formed between the tip and the air. Once the potential difference that breaks through the air is reached, the metal tip will emit bursts of electric sparks. No matter it is rectangular or needle-shaped, there is a tip. Places, such as the corner part of a rectangle, the tip of a needle, etc., only a circle has no tip discharge phenomenon, and it is not easy to attract lightning. Therefore, the spherical protective shell covers the outside of the signal receiver, which is convenient for preventing the sharp antenna part of the signal receiver from attracting lightning, and the outer walls of the first lightning protection shell 301 and the second lightning protection shell 304 are coated with metal conductive paint. The metal conductive paint has a conductive property. When lightning approaches the lightning protection shell, electrostatic induction occurs, and the charged body causes ion oscillation in the electron cloud of the metal, thereby forming an electric field inside the metal shell. Due to the conductivity of the metal, these electric fields can be naturally distributed and dissipated on the surface of the metal shell, and will not enter the interior of the lightning protection shell, and will not affect the signal receiver inside the lightning protection shell;

[0034] When it is not a thunderstorm, the second lightning protection shell 304 can be turned open to expose the signal receiver and continue to receive signals. In the autumn and winter seasons, when there is rain but no lightning, the second lightning protection shell 304 is also in an open state. At the same time, the blocking cover 308 is opened, and the rainwater inside the second lightning protection shell 304 can be discharged from the second drain port 306, and the rainwater in the first lightning protection shell 301 can be discharged from the first drain port 302 at its bottom.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
