Description

Technical Field

[0001] The present invention relates to the technical field of satellite antennas, and in particular to a satellite antenna. Background Art

[0002] Satellite antennas, as key equipment for receiving and sending satellite signals, their stability and performance are crucial to the quality of communication; and various factors in the external environment, such as wind, rain, sunshine, temperature changes, etc., may have adverse effects on satellite antennas, thereby affecting their normal operation. Therefore, satellite antennas need to be protected. Its main function is to protect the antenna system from the influence of the external environment.

[0003] The high-frequency head is a key component in the satellite antenna system, responsible for receiving and converting weak signals from the satellite. Since it is directly exposed to the external environment, it is particularly susceptible to adverse weather factors such as wind, rain, lightning, temperature changes and physical shocks. The existing automatic antenna protective cover can automatically sense rain or high temperature weather through sensors. When rain or high temperature weather is sensed, the protective cover body in the retractable slot automatically opens to protect the antenna and prevent rain, high temperature and other adverse weather from affecting the antenna body, greatly improving the service life of the antenna. However, when the protective cover is used to protect the entire antenna, the protective cover will affect the reception of satellite signals and also have a great impact on the heat dissipation function of the satellite high-frequency head.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Reference Figure 1-Figure 11 , including a parabolic reflection pot body 1 and a mounting base plate 2 as a mounting carrier for mounting the parabolic reflection pot body 1, and also including: a plurality of fixing frames 6 are fixedly connected to the surface of the parabolic reflection pot body 1, a protective outer cover 5 is provided on the fixing frame 6, a high-frequency head body 15 is provided in the protective outer cover 5, and the high-frequency head body 15 is fixedly connected to the fixing frame 6 extending into the protective outer cover 5; a cleaning component 8 for cleaning the surface of the parabolic reflection pot body 1 is provided on the parabolic reflection pot body 1; a power chamber 10 is provided on the parabolic reflection pot body 1, a receiving chamber 11 is provided on the power chamber 10, a driving gear 17 for driving the cleaning component 8 is provided in the power chamber 10, and a turbine 18 rotating synchronously with the driving gear 17 is provided in the receiving chamber 11; a through pipe 12 is connected between the receiving chamber 11 and the protective outer cover 5, and a vent 14 is opened on the bottom surface of the protective outer cover 5.

[0023] In the present invention, the parabolic reflector dish 1 and the tuner body 15 cooperate to receive and transmit signals; When in use, the cleaning component 8 cleans the surface of the parabolic reflective pot 1 to prevent external pollutants from adhering to the surface of the parabolic reflective pot 1 and affecting the reception and transmission of signals of the parabolic reflective pot 1; The protective cover 5 is made of materials with good weather resistance and corrosion resistance such as polyvinyl chloride (PVC), engineering plastics (ABS) or polycarbonate. These materials are relatively low in cost. At the same time, these materials also have certain wave transmission properties and have little interference with the signal of the tuner body 15. When the turbine 18 is running, a suction effect will be generated, and the air in the protective outer cover 5 will be drawn out through the through pipe 12, and the external cold air will be sucked into the protective outer cover 5 through the vent hole 14, thereby accelerating the cooling of the high-frequency head body 15. The high-frequency head body 15 will generate heat during operation. If the heat is not dissipated in time, its performance may be reduced or even damaged. The flow of cold air can take away the heat on the high-frequency head body 15, thereby reducing its temperature and ensuring its normal operation.

[0024] Reference Figure 1-Figure 11 A support frame 3 is provided on the mounting base plate 2 , a rotating assembly 4 is fixedly connected to the support frame 3 , and the parabolic reflection pot body 1 is fixedly connected to the rotating assembly 4 .

[0025] In the present invention, the mounting base plate 2 is the cornerstone of the entire structure, which provides a stable mounting platform. The mounting base plate 2 is usually made of solid material to ensure that it can withstand the weight of the entire structure and the force generated during operation; the support frame 3 includes a plurality of vertical poles and horizontal plates; the rotating component 4 is fixedly connected to the support frame 3, and is used to realize the rotation and tilting functions of the parabolic reflection pot body 1. By loosening the fastening screws on the rotating component 4 and then controlling the rotating component 4, the direction and angle of the parabolic reflection pot body 1 can be adjusted to adapt to different signal reception or energy focusing requirements. After the adjustment is completed, the fastening screws are tightened again to prevent the rotating component 4 from rotating.

[0026] Reference Figure 1-Figure 11 The two ends of the protective cover 5 are provided with end covers 13 , the bottom surface of one end of the protective cover 5 is provided with a vent hole 14 , and the bottom surface of the other end of the protective cover 5 is connected to the through pipe 12 .

[0027] In the present invention, the bottoms of the end caps 13 at both ends of the protective cover 5 extend out, so that the vent holes 14 have a certain degree of protection capability, and rain and snow can be prevented from entering the protective cover 5; When the turbine 18 rotates, a suction effect is generated, and the air in the protective outer cover 5 is drawn out through the through pipe 12, and the external cold air is sucked into the protective outer cover 5, thereby accelerating the cooling of the high-frequency head body 15. The high-frequency head body 15 generates heat during operation. If the heat is not dissipated in time, its performance may be reduced or even damaged. The flow of cold air can take away the heat on the high-frequency head body 15, thereby reducing its temperature and ensuring its normal operation.

[0028] Reference Figure 1-Figure 11 A mounting ring 7 is fixedly connected to the edge of the parabolic reflector pot body 1, and an annular groove is provided on the mounting ring 7 near the edge of the center of the circle. A ring gear 19 is rotatably connected in the annular groove, and the cleaning component 8 is fixedly connected to the ring gear 19; a driving gear 17 is meshed and connected to the ring gear 19, and a driving part 9 is provided on the mounting base plate 2, and the driving gear 17 is connected to the output end of the driving part 9 through a driving rod 16.

[0029] In the present invention, an arc-shaped stopper 1901 is provided on the ring gear 19, and the arc surface of the arc-shaped stopper 1901 fits with the inner ring of the ring gear 19. The arc-shaped stopper 1901 can assist the ring gear 19 to rotate more stably, and at the same time, the arc-shaped stopper 1901 can prevent contamination impurities from entering the power chamber 10; The driving part 9 is a servo motor, which is used to drive the driving gear 17 to rotate. The driving gear 17 drives the ring gear 19 to rotate. The ring gear 19 rotates, so that the cleaning component 8 performs a circular motion on the parabolic reflective pot body 1 to comprehensively clean the parabolic reflective pot body 1.

[0030] Reference Figure 1-Figure 11A notch groove is provided at the bottom of the mounting ring 7 , and the notch groove and the parabolic reflective pot body 1 form a drainage groove 20 .

[0031] In the present invention, dust, bird droppings, rain and snow and other polluting impurities are easily accumulated on the parabolic reflective pot 1. The main function of the parabolic reflective pot 1 is to reflect or focus energy, such as electromagnetic waves. When the surface is covered with polluting impurities, the reflection efficiency will be significantly reduced. For applications such as radar antennas, the polluting impurities on the parabolic reflective pot 1 will interfere with the reception and transmission of signals. Impurities such as bird droppings and dust may cause signal attenuation, distortion or complete loss, thereby affecting the performance and accuracy of the radar system. In addition, polluting impurities such as rain, snow, and bird droppings contain corrosive substances, such as acids and salts, which will accelerate the corrosion and aging process of the surface of the parabolic reflective pot 1. If exposed to these polluting impurities for a long time, the material and coating of the parabolic reflective pot 1 may be seriously damaged. The cleaning brush 1 801 and the cleaning brush 2 2301 will sweep away the pollutants on the parabolic reflective pot body 1 , and the pollutants will be discharged through the drain trough 20 , thereby preventing excessive accumulation of pollutants on the parabolic reflective pot body 1 .

[0032] Reference Figure 1-Figure 11 , the mounting ring 7 and the power chamber 10 are connected.

[0033] In the present invention, the connection between the mounting ring 7 and the power chamber 10 is interconnected, so that the ring gear 19 and the driving gear 17 can be meshed and connected together. At the same time, since the connection between the mounting ring 7 and the power chamber 10 is interconnected, when the turbine 18 is running, the turbine 18 will pump the hot air in the protective outer cover 5 into the power chamber 10, and the hot air entering the power chamber 10 will be dispersed through the connection gap between the mounting ring 7 and the ring gear 19, so that dust and impurities from the outside and dust and water droplets cleaned by the cleaning brush 1 801 and the cleaning brush 2 2301 can be prevented from entering the connection gap between the mounting ring 7 and the ring gear 19. Through such a design, the ring gear 19 and the driving gear 17 can be prevented from being contaminated, thereby ensuring their stable and efficient operation. At the same time, the hot air entering the power chamber 10 can remove and quickly dry the water vapor on the power chamber 10 and the ring gear 19, thereby extending the service life of the ring gear 19 and the driving gear 17.

[0034] Reference Figure 1-Figure 11 A cleaning brush 801 is provided at the bottom of the cleaning component 8, a slide groove 21 is opened in the cleaning component 8, a slide bar 23 is slidably connected in the slide groove 21, and a cleaning brush 2301 is provided at the bottom of the slide bar 23; a limit block 22 is provided at the end of the slide groove 21, and a gravity block 24 cooperating with the limit block 22 is provided at one end of the slide bar 23.

[0035] In the present invention, due to the shape characteristics of the parabolic reflective pot body 1, pollutants are more likely to adhere to the lower half of the parabolic reflective pot body 1. The cleaning brush 1 801 is a hard brush, which can strongly clean the lower half of the parabolic reflective pot body 1. The cleaning brush 2 2301 is a soft brush, which can more thoroughly remove pollutants. As the cleaning assembly 8 rotates, when the cleaning assembly 8 rotates to the upper half of the parabola reflective pot body 1, under the action of centrifugal force and gravity (especially the gravity of the gravity block 24), the slide bar 23 slides out of the slide groove 21, so that the cleaning brush 2 2301 on the extended slide bar 23 and the cleaning brush 1 801 on the cleaning assembly 8 form a long-haired brush, which can clean the central part of the parabola reflective pot body 1 (only when the cleaning assembly 8 rotates to the upper half of the parabola reflective pot body 1, the extended slide bar 23 cooperates with the cleaning assembly 8 to clean most areas of the parabola reflective pot body 1). When the cleaning assembly 8 rotates to the lower half of the parabola reflective pot body 1, under the action of the gravity of the gravity block 24 and the slide bar 23, the slide bar 23 retracts into the slide groove 21, and at this time only the cleaning brush 1 801 cleans the lower half of the parabola reflective pot body 1; By controlling the sliding out and retracting of the slide bar 23, the length of the entire cleaning component can be controlled to prevent the excessively long cleaning component from blocking the reflection of the satellite signal by the parabolic reflector pot body 1.

[0036] Reference Figure 1-Figure 11 The high-frequency head body 15 is located at the signal reflection focus of the parabolic reflection pot body 1.

[0037] In the present invention, since the parabolic reflection pot body 1 can reflect and concentrate the signal to the focus, the high-frequency head body 15 is located at the focus and can receive the strongest signal, thereby improving the signal reception efficiency. At the same time, the high-frequency head body 15 is located at the focus, which can ensure the stability of the received signal quality and reduce the image deformation and interference caused by signal fluctuations; and the high-frequency head body 15 is located at the focus, which makes installation and adjustment more convenient. It only needs to adjust the direction and angle of the parabolic reflection pot body 1 to ensure that the high-frequency head body 15 receives the strongest signal.

[0038] 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.
