[0023] Reference Figure 1-Figure 8A satellite antenna with high-efficiency signal amplification includes an installation box 1, an antenna body 2 is arranged above the installation box 1, an electrical component group 21 is installed inside the installation box 1, and an adjustment plate 4 distributed at equal intervals is arranged in the installation box 1 to evenly disperse the airflow entering the installation box 1; a cooling member is installed on the inner wall of one side of the installation box 1 to cool the electrical component group 21; a T-shaped rod 5 is installed on one side of the adjustment plate 4, and when the T-shaped rod 5 moves up and down, it drives the adjustment plate 4 to rotate and adjust, and at the same time, the airflow passing through the T-shaped rod 5 is diverted and transported to the inner wall of the installation box 1.

[0024] In the prior art, when a satellite antenna is working, it is necessary to improve the reception or transmission performance of satellite signals. Generally, electrical components such as low-noise amplifiers and stacked power amplifiers and digital signal processing technology are added to the antenna system to achieve higher output power and efficiency and reduce interference with satellite signals. However, since these electrical component groups 21 are installed in the installation box 1, a large amount of heat is generated under long-term working conditions. If the temperature is not cooled in time, it will easily cause failures and reduce the performance of satellite signal reception. Although fans are installed in the prior art for cooling by blowing air, due to the different distribution positions of these electrical components, the cooling effect of a single fan is poor. In addition, some satellite antennas are installed in harsh environments such as high temperatures and are more susceptible to the influence of high temperature environments. In this solution, by installing a fan in the installation box 1, the fan can be cooled by the fan. An adjusting plate 4 is arranged inside to evenly disperse the incoming cold air and increase the blowing range of the airflow. The heat dissipation and cooling of the electrical components installed in various parts of the installation box 1 can be carried out. At the same time, when the inside of the installation box 1 is cooled by blowing air, the T-shaped rod 5 can be driven to move up and down. During the lifting operation, part of the airflow passing through the T-shaped rod 5 can be collected and then enter the inside of the connecting tube 51, and finally transported to the central part of one side of the adjusting plate 4, thereby improving the overall uniformity and strength of the airflow after passing through the adjusting plate 4. Among them, when the T-shaped rod 5 reciprocates up and down, part of the airflow can also be collected and then transported to the inner wall of the installation box 1, so that an air protection layer is formed in the inner wall of the installation box 1, which blocks the external temperature from being transmitted to the inside of the installation box 1, making the satellite antenna more stable when used in harsh environments.

[0025] In a preferred embodiment, referring to Figure 6 , Figure 7 and Figure 8The cooling component includes a mounting frame 30 fixed to the inner wall of the mounting box 1, a driving unit 31 is installed on the mounting frame 30, a fan blade 32 is installed on the output end surface of the driving unit 31, an eccentric wheel 33 is fixed to the output end of the driving unit 31, a moving plate 43 is attached to the surface of the eccentric wheel 33, a moving rod 42 is fixed to one end of the moving plate 43, a connecting frame 41 is fixed to the end of the moving rod 42, one side of the connecting frame 41 is rotatably connected to a plurality of adjustment plates 4 through a pin shaft, and the plurality of adjustment plates 4 are rotatably connected to the mounting box 1 through a pin shaft, an extrusion spring 40 is fixed to the top of the connecting frame 41, and the end of the extrusion spring 40 is fixedly connected to the mounting box 1.

[0026] Among them, the driving part 31 is a private service motor. When working, it can introduce external cold air into the interior of the installation box 1, blow air to dissipate heat and cool down the electrical component group 21 inside the installation box 1. After the cold air enters the interior of the installation box 1, the eccentric wheel 33 rotates and squeezes to drive the movable plate 43 to move up and down. Under the elastic rebound force of the squeezing spring 40, multiple adjustment plates 4 swing up and down, so that the incoming air flow is evenly dispersed through multiple adjustment plates 4, and the blowing range of the air flow is improved, so that the electrical component group 21 installed in the installation box 1 can obtain a better blowing and cooling effect. Compared with the blowing form in a single position state in the prior art, the cold air blowing range is wider, and after being evenly dispersed, the airflow is smoother, avoiding strong air from causing damage to the electrical component group 21, and there is no need to add too many power sources, saving manufacturing costs. A dust net and a filter can be installed on one side of the mounting frame 30 to avoid the air entering the installation box 1 from being affected by dust and moisture.

[0027] In a preferred embodiment, referring to Figure 4 and Figure 5 The top of the movable plate 43 is fixedly connected to one end of the T-shaped rod 5, and the other end of the T-shaped rod 5 is slidably connected to the connecting tube 51. The top of the connecting tube 51 is fixed to the inner wall of the installation box 1. A first chamber 52 is arranged in the connecting tube 51. A first air inlet pipe 53 is installed at one end of the connecting tube 51. An exhaust pipe 54 is fixed at one end of the connecting tube 51. The exhaust pipe 54 slides through the movable plate 43. A one-way valve is arranged at the connection between the exhaust pipe 54 and the first air inlet pipe 53 and the connecting tube 51. A second chamber 61 is provided, and a second air inlet pipe 62 is fixed to the other end of the connecting tube 51, and a delivery pipe 63 is fixed to the other end of the connecting tube 51 on one side of the second air inlet pipe 62, and one end of the delivery pipe 63 is connected to a protective part, and the protective part includes an isolation chamber 64 opened on the inner wall of the installation box 1, and the delivery pipe 63 is connected to the isolation chamber 64. A heat sink 65 is embedded in the inner wall of the bottom of the installation box 1, and a ventilation pipe 66 is installed at the bottom of the installation box 1, and a one-way valve is provided at the connection between the second air inlet pipe 62 and the delivery pipe 63 and the connecting tube 51.

[0028] The above scheme is adopted, wherein the T-shaped rod 5 is composed of a piston and a connecting rod. When the movable plate 43 reciprocates up and down, the T-shaped rod 5 is driven to slide inside the connecting tube 51. When the connecting tube 51 reciprocates, the air blown into the installation box 1 through the fan blades 32 can be extracted through the first air inlet pipe 53, and then transported to the inside of the first chamber 52, and finally ejected through the exhaust pipe 54, and the ejection end of the exhaust pipe 54 is located between the adjustment plate 4 and the cooling element. When the airflow passes through the adjustment plate 4, it will not be disturbed by the eccentric wheel 33. The airflow passing through multiple adjustment plates 4 can be more uniform, and the airflow can be transported through the extraction, extrusion and transportation steps to improve the strength of the airflow transportation, thereby further improving the effect of blowing and cooling. Another part of the airflow is drawn into the interior of the second chamber 61 through the second air inlet pipe 62, and then transported to the interior of the isolation chamber 64 through the delivery pipe 63. The airflow forms a "protective layer" in the isolation chamber 64 to isolate the temperature inside and outside the installation box 1, thereby preventing the external temperature from being transferred to the interior of the installation box 1 and causing interference. The heat sink 65 can conduct the heat in the isolation chamber 64, and the airflow is finally discharged through the ventilation pipe 66.

[0029] A mounting member 101 is installed on the top of the mounting box 1, one end of the mounting member 101 is installed together with the antenna body 2, one side of the mounting box 1 is rotatably connected to a box door 7 through a hinge, a sealing strip is provided on the box door 7, a mounting tube 8 is installed on the inner wall of the top of the mounting box 1, and a rubber sleeve is provided on the inner wall of the mounting tube 8; The mounting member 101 includes a mounting base and a driving motor installed on the mounting base. The motor drives the antenna body 2 to rotate and adjust the elevation angle of the antenna body 2 to adjust the signal transmission. The sealing strip on the box door 7 can be sealed and closed using the box door 7 to prevent external heat from entering the installation box 1. The installation tube 8 is provided to facilitate wiring.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
