Existing micro-rain radars are generally installed in open environments, such as on rooftops or streetlights, thus requiring protection, such as installing a radar dome. Current domes are mostly spherical or cylindrical in shape, but snow can still accumulate on the top of the dome during snowfall. Snow accumulation can cause signal attenuation and increase measurement errors; if the snow accumulation is large, it can directly affect the radar's transmission and reception capabilities, blocking electromagnetic wave propagation and causing the radar to malfunction. Therefore, the micro-rain radar dome needs to be snow-proof. Simultaneously, the dome must have sufficient strength to resist damage from birds. Utility model content:

Several annularly distributed grooves 14 are formed on the inner wall of the thickened wall 13 and penetrate through the lower end face of the thickened wall 13. A circular aluminum alloy heat-conducting ring 3 is inserted into the bottom of the body 12. The upper end face of the aluminum alloy heat-conducting ring 3 abuts against the lower end face of the thickened wall 13. The outer ring of the upper end face of the aluminum alloy heat-conducting ring 3 is formed with several vertical heat-conducting plates 31, which are respectively inserted into the slots 14 of the cover body 12. The outer ring of the lower end face of the aluminum alloy heat-conducting ring 3 is formed with a downwardly extending connecting sleeve 34. Several annularly distributed second bolts 6 are screwed onto the connecting sleeve 34, and the ends of the second bolts 6 are inserted into the cover body 12.

[0022] An annular connecting plate 21 is formed on the outer wall of the middle part of the mounting bracket 2. The connecting plate 21 is inserted into the connecting sleeve 34 of the aluminum alloy heat-conducting ring 3 and abuts against the lower end face of the aluminum alloy heat-conducting ring 3. An annular heating wire mounting groove 33 is formed on the lower end face of the aluminum alloy heat-conducting ring 3. A carbon fiber heating wire 4 is inserted and fixed in the heating wire mounting groove 33. An annular connecting plate 32 is formed on the inner ring of the aluminum alloy heat-conducting ring 3. Several annularly distributed first bolts 5 are inserted into the connecting plate 32. The lower end of the first bolts 5 is screwed and fixed to the connecting plate 21. An annular radar mounting plate 7 is fixedly connected to the upper end of the mounting bracket 2. The radar mounting plate 7 is set in the thickened wall 13 on the upper side of the heat-conducting plate 31.

[0023] The central axis of the silicon nitride ceramic cover 1, the central axis of the mounting bracket 2, and the central axis of the aluminum alloy heat-conducting ring 3 coincide;

[0024] The first bolt 5, the second bolt 6, and the heat-conducting plate 31 are all uniformly distributed in a ring around the central axis of the aluminum alloy heat-conducting ring 3.

[0025] The bottom outer ring of the mounting bracket 2 is formed with several annularly evenly distributed mounting holes. The outer wall of the connecting plate 21 on the mounting bracket 2 abuts against the inner wall of the connecting sleeve 34, and the outer wall of the connecting sleeve 34 abuts against the inner wall of the bottom of the cover 12.

[0026] A wire-passing groove 35 is formed on the side wall of the heating wire mounting groove 33 on the aluminum alloy heat-conducting ring 3, which passes through the connecting plate 32. A wire-passing hole is formed on the mounting bracket 2, which is connected to the wire-passing groove 35. The wiring of the carbon fiber heating wire 4 can pass through the wire-passing groove 35 and the wire-passing hole and be electrically connected to the power cord inside the mounting bracket 2.

When it snows, the remote switch can be turned on to heat the silicon nitride ceramic cover 1 through the carbon fiber heating wire 4, thereby preventing snow from accumulating on the silicon nitride ceramic cover 1. The heating temperature of the carbon fiber heating wire 4 is 20℃~30℃.

[0027] The thickness of the heat-conducting plate 31 on the aluminum alloy heat-conducting ring 3 is equal to the width of the slot 14 on the cover 12; this increases the contact area between the heat-conducting plate 31 and the cover 12, thereby improving the heat conduction effect.

[0032] Working principle: This structure is a highly reliable rain radome structure that protects against snow accumulation and bird damage. It includes the main body of the rain radome and its installation and connection structure. The rain radome is composed of a silicon nitride ceramic cover 1 consisting of an arc-shaped top 11 and a cylindrical ring-shaped cover 12. The silicon nitride ceramic cover 1 itself can resist bird damage by utilizing the material properties of the silicon nitride ceramic cover 1.

[0033] Meanwhile, compared with other ceramic materials, it has better thermal conductivity. Therefore, an aluminum alloy heat-conducting ring 3 is set between the silicon nitride ceramic cover 1 and the mounting bracket 2. A carbon fiber heating wire 4 is installed inside the aluminum alloy heat-conducting ring 3. The carbon fiber heating wire 4 can generate heat when energized. The heat can be transferred to the silicon nitride ceramic cover 1 through the aluminum alloy heat-conducting ring 3 and the heat-conducting plate 31 on the aluminum alloy heat-conducting ring 3 to raise the temperature. As a result, the snowflakes falling on the silicon nitride ceramic cover 1 will melt and flow down as water, without snow accumulation. At the same time, ceramic materials have good corrosion resistance, and the silicon nitride ceramic cover 1 has a long service life as a rain radar cover.

[0034] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
