[0003] In order to protect the array antenna, the antenna is usually installed in a protective cover. Under the protection of the protective cover, the antenna is not easily damaged. However, since the protective cover is in a sealed state, a resonant cavity is easily formed in the enclosed space, resulting in a decrease in effective radiation power and a reduction in coverage radius, thereby reducing the signal transmission quality.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-3 A 5G high-gain array antenna comprises a fixing base 1, which is fixedly connected to a base standing column 2. A plurality of fixing plates 3 are connected to the fixing base 1 at equal intervals along the axis direction. One end of each fixing plate 3 is fixedly connected to a protective cover 4. An antenna body 7 is fixedly connected to each protective cover 4. A linear motor 8 is fixedly connected to the inner wall of each protective cover 4. The output end of each linear motor 8 is fixedly connected to a retractable absorbing nail array member 9 through a connecting shaft 11. Each retractable absorbing nail array member 9 is located on the outside of the corresponding antenna body 7. A plurality of heat dissipation scales 10 are connected to each protective cover 4 at equal intervals along the axis direction. An inspection port 5 is opened at the upper end of each protective cover 4, and a sealing plate 6 is sealed in each inspection port 5.

[0020] Working principle: The fixing base 1 is fixed on the base standing column 2. The fixing base 1 fixes the protective cover 4 through the fixing plate 3. The protective cover 4 protects the antenna body 7. When the antenna body 7 is working, the linear motor 8 is started and drives the retractable absorbing nail array member 9 to move through the connecting shaft 11. After the retractable absorbing nail array member 9 moves, the equivalent dielectric constant in the protective cover 4 is changed, the resonance condition is destroyed, and the standing wave distribution is disturbed. The resonant cavity effect will not be formed in the protective cover 4, thereby preventing the effective radiation power from being reduced and the coverage radius from being shortened, thereby improving the signal transmission quality. At the same time, the heat generated by the antenna body 7 after operation will increase the internal temperature of the protective cover 4. Several heat dissipation scales 10 improve the heat dissipation performance of the protective cover 4, preventing the antenna body 7 from burning due to the increase in the internal temperature of the protective cover 4. When the antenna body 7 fails, the sealing plate 6 can be removed and maintenance can be carried out through the inspection port 5, thereby facilitating the maintenance of the internal components of the protective cover 4.

[0021] Example 2: The fixing base 1 fixes the protective cover 4 through the fixing plate 3. In windy weather, since the protective cover 4 has only one fixed position, it is easy to cause the connection between the fixing plate 3 and the protective cover 4 to crack, thereby affecting the use of the protective cover 4. Figure 2-3 As another preferred embodiment of the present invention, the difference from Example 1 is that a positioning mechanism 12 is connected between the plurality of protective covers 4, and the positioning mechanism 12 includes a plurality of limiting seats 121, and the plurality of limiting seats 121 are sleeved to the bottom ends of the corresponding protective covers 4. A connecting rod 122 is fixedly connected between two adjacent limiting seats 121, and the plurality of limiting seats 121 and the connecting rod 122 are an integral structure. A first connecting plate 123 is connected to the plurality of connecting rods 122, and one end of each first connecting plate 123 is fixedly connected to the fixing plate 3; The fixing plate 3 fixes the first connecting plate 123, and the first connecting plate 123 fixes the limiting seat 121. Several limiting seats 121 are limited by the connecting rod 122. After the limiting seat 121 is sleeved on the bottom end of the protective cover 4, the protective cover 4 is limited to prevent the protective cover 4 from shifting, so that the connection between the fixing plate 3 and the protective cover 4 will not crack, thereby improving the fixing effect of the protective cover 4.

[0022] Example 3: When the protective cover 4 protects the antenna body 7, the protective cover 4 is in the air. In rainy, snowy, and hail weather, the hail collides with the protective cover 4, and the protective cover 4 is prone to cracking due to the collision, thereby exposing the antenna body 7 and easily causing damage to the antenna body 7. Figure 4-7As another preferred embodiment of the present invention, the difference from embodiment 1 is that a shielding mechanism 13 is connected to the fixed base 1 to prevent the protective cover 4 from breaking due to collision. The shielding mechanism 13 includes a fixed rod 131, one end of the fixed rod 131 is fixedly connected to the fixed base 1, and the other end of the fixed rod 131 is fixedly connected to a groove frame 132. The groove frame 132 is located just above the fixed base 1. An electric telescopic rod 133 is fixedly connected to the groove frame 132. The telescopic end of the electric telescopic rod 133 is fixedly connected to a movable frame 134. The base column 2 passes through the movable frame 134. The inner wall of the movable frame 134 is aligned with the base column 2. There is a gap between the columns 2. The axis of the movable frame 134 is in the same straight line as the axis of the groove frame 132. A plurality of second connecting plates 135 are rotatably connected to the movable frame 134 along the axis direction at equal intervals. One end of each second connecting plate 135 is rotatably connected to a shielding assembly 136. Several shielding assemblies 136 are located above the corresponding protective cover 4. One end of each shielding assembly 136 is rotatably connected to the same mounting frame 137. The bottom end of the mounting frame 137 is rotatably connected to a plurality of third connecting plates 138 along the axis direction at equal intervals. One end of each third connecting plate 138 is connected to the fixed seat 1. In rainy, snowy, or hail weather, the electric telescopic rod 133 is activated to drive the movable frame 134 to move downward by a set distance. After the movable frame 134 moves downward, the corresponding shielding components 136 are deployed through the plurality of second connecting plates 135. The shielding components 136 are smoothly deployed under the limit of the mounting frame 137. The plurality of shielding components 136 are located above the corresponding protective covers 4 to protect the protective covers 4 and prevent collisions between the hail and the protective covers 4. Thus, the protective covers 4 will not be cracked due to the collisions, thereby improving the protective effect of the protective cover 4 on the antenna body 7 and making the antenna body 7 less susceptible to damage. In clear weather, the electric telescopic rod 133 drives the movable frame 134 to move upward a set distance. After the movable frame 134 moves upward, the several shielding components 136 are retracted and folded, exposing the several protective covers 4, thereby not affecting the operation of the antenna body 7 in the protective cover 4.

[0023] Example 4: The shielding component 136 blocks hail to prevent the protective cover 4 from cracking due to collision. Due to the high collision intensity, the shielding component 136 is easily deformed, thereby losing the hail blocking effect. Figure 6-7 As another preferred embodiment of the present invention, the difference from embodiment 3 is that the shielding assembly 136 includes a fourth connecting plate 1361, one end of the fourth connecting plate 1361 is rotatably connected to the mounting bracket 137, the upper end of the fourth connecting plate 1361 is rotatably connected to the second connecting plate 135, the other end of the fourth connecting plate 1361 is rotatably connected to a shielding member 1362, the bottom end of the shielding member 1362 is fixedly connected to a spring 1363, and one end of the spring 1363 is fixedly connected to the fourth connecting plate 1361; Shielding member 1362 includes a baffle 13621, one side of which is rotatably connected to fourth connecting plate 1361. The bottom end of baffle 13621 is connected to spring 1363. Baffle 13621 is an aluminum alloy plate, tilted downward, and coated with an oleophobic coating. Baffle 13621 defines a chamber 13622, which contains a honeycomb core 13623. When hail collides with the baffle 13621, the baffle 13621 rotates downward due to the collision. After the baffle 13621 rotates downward, it compresses the spring 1363. The spring 1363 is compressed and generates an elastic force. The elastic force generated by the spring 1363 cushions the baffle 13621 and blocks the rotation of the baffle 13621. The elastic force generated by the compression of the spring 1363 cushions the baffle 13621, thereby reducing the collision intensity between the baffle 13621 and the hail, making the baffle 13621 less likely to be damaged after being hit by the hail, thereby extending the service life of the baffle 13621. At the same time, a chamber 13622 is provided in the baffle 13621 , and the chamber 13622 is filled with a honeycomb core 13623 , which reduces the weight of the baffle 13621 , and the oleophobic coating improves the smoothness of the surface of the baffle 13621 , making it easier for rainwater to clean the surface of the baffle 13621 .

[0024] Example 5: When the electric telescopic rod 133 drives the movable frame 134 to move in the vertical direction, the telescopic end of the electric telescopic rod 133 is easily frozen in cold weather, thereby causing the telescopic end of the electric telescopic rod 133 to be unable to reset. Figure 8-10 As another preferred embodiment of the present invention, the difference from Example 3 is that an antifreeze mechanism 14 for protecting the electric telescopic rod 133 is connected to the groove frame 132. The antifreeze mechanism 14 includes a first open cover 141, which is fixedly connected to the bottom end of the groove frame 132. The bottom end of the first open cover 141 is folded and connected to a plurality of second open covers 142. The second open covers 142 at the bottom are connected to the movable frame 134. The electric telescopic rod 133 is located inside the first open cover 141 and the second open cover 142. A fixing pipe 143 is fixedly connected to the first open cover 141, and a heating pipe 144 is connected to the fixing pipe 143. When the electric telescopic rod 133 drives the movable frame 134 to move downward, the movable frame 134 drives the second open cover 142 to move downward. After the second open cover 142 moves downward, it unfolds. The unfolded second open covers 142 protect the telescopic end of the electric telescopic rod 133 to prevent rain from falling on the telescopic end of the electric telescopic rod 133, thereby preventing ice from forming on the telescopic end of the electric telescopic rod 133. At the same time, the heating tube 144 generates heat after being powered on. The generated heat is transferred to the first open cover 141, and the first open cover 141 transfers the heat to the second open cover 142. After the heat on the second open cover 142 is dissipated, it contacts the telescopic end of the dynamic telescopic rod 133, thereby increasing the temperature on the telescopic end of the dynamic telescopic rod 133 and preventing ice from forming on the telescopic end of the dynamic telescopic rod 133, thereby ensuring that the telescopic end of the dynamic telescopic rod 133 can be retracted and reset.

[0025] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
