Description

Technical Field

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

[0002] Satellite antennas mainly function by receiving electromagnetic wave signals transmitted by satellites. When satellites are orbiting in space, they continuously send high-frequency electromagnetic waves containing various information (such as TV program signals, communication signals, weather data signals, etc.) to the surface of the earth. The parabola (usually in the shape of a dish) of the satellite antenna can reflect these weak signals and converge them onto the high-frequency head at the focal position. The function of the high-frequency head is to amplify and down-convert the received high-frequency signals, converting them into lower-frequency signals so that subsequent signal processing equipment (such as satellite receivers) can decode them and perform other operations.

[0003] At present, satellite antenna interference cancellers are usually installed on the supporting columns of satellite antennas to offset or reduce the influence of interference. In order to make the interference canceller work better, air cooling is usually adopted. However, since the satellite antenna is at a high place, especially in some open or harsh environmental conditions, the surface of the heat dissipation window of the interference canceller is easily adsorbed on the surface of the heat dissipation window due to air circulation and internal heating of the interference canceller, and even some particles such as hair are accumulated on the heat dissipation window, resulting in the internal heat of the interference canceller unable to be discharged, which can easily cause a short circuit in the internal circuit and eventually lead to damage. However, the traditional way of cleaning the heat dissipation window is generally to manually climb up with the help of tools and then manually clean it. This cleaning method is too dangerous and increases labor intensity, resulting in slow efficiency and inability to achieve automatic control of cleaning the heat dissipation window.

[0021] In the present invention, while the fan 4 rotates, the active rod 6 is driven to rotate continuously, and through the first synchronous belt 8, the driven rod 7 is driven to keep rotating, thereby driving the circular cylinder 9 to rotate continuously. The automatic control mechanism 11 can automatically control the first rotating rod 10 to follow the rotation of the circular cylinder 9, thereby causing the half gear 12 to rotate and repeatedly mesh with the teeth on the inner walls of both sides of the rectangular frame 13, thereby causing the rectangular frame 13 to slide back and forth left and right, thereby driving the two brush plates 15 to slide back and forth left and right on the surface of the heat dissipation window 5 through the T-shaped connecting plate 14 at the bottom, so that dust, particles, hair and other dirt on the heat dissipation window 5 can be removed, and the through hole of the heat dissipation window 5 is kept open, which is helpful to circulate the air in the adaptive interference canceller box 3 and maintain good heat dissipation. There is no need for manual cleaning by humans, which greatly reduces the labor intensity of the staff.

[0022] In some embodiments, the heat dissipation window 5 is set to be inclined, the first rotating rod 10 passes through the adaptive interference canceller box 3, the left side of the fan 4 is fixedly connected to the left inner wall of the adaptive interference canceller box 3, the outer sleeve of the half gear 12 and the rectangular frame 13 is provided with a waterproof box 1201, the waterproof box 1201 is fixedly connected to the adaptive interference canceller box 3, a slide groove is opened at the bottom of the waterproof box 1201, and the T-shaped connecting plate 14 is slidably connected to the slide groove of the waterproof box 1201.

[0023] In the present invention, the tilted setting of the heat dissipation window 5 can effectively prevent rainwater from entering the interior of the adaptive interference canceller box 3, and the waterproof box 1201 can prevent rainwater from contacting the half gear 12 and the rectangular frame 13, making it convenient for the half gear 12 and the rectangular frame 13 to move stably.

[0024] A slide plate 16 is fixedly connected to the right bottom surface of the adaptive interference canceller box 3, and two groups of brush plates 15 are provided, and the two groups of brush plates 15 are symmetrically arranged with the center line of the T-shaped connecting plate 14 as the symmetry axis. A slide rod 17 is fixedly connected to the bottom surface of the two groups of brush plates 15, and the slide rod 17 is slidably connected in the slide plate 16.

[0025] In the present invention, by sliding two sets of sliding rods 17 in the slide slot plate 16 , the sliding directions of the two brush plates 15 can be limited, which helps to make the sliding of the brush plates 15 more stable.

[0026] The automatic control mechanism 11 includes a fixed plate 18, which is fixedly connected to the top inner wall of the adaptive interference canceller box 3. A telescopic rod 19 penetrates the bottom surface of the fixed plate 18. The telescopic rod 19 is rotatably connected to the fixed plate 18, and the right end of the telescopic rod 19 is fixedly connected to the first rotating rod 10.

[0027] In the present invention, the fixing plate 18 facilitates the support of the telescopic rod 19, which helps to make the rotation of the telescopic rod 19 more stable.

[0028] A slide groove is provided on the left side surface of the telescopic rod 19, and a rectangular plate 20 passes through the slide groove surface of the telescopic rod 19. The rectangular plate 20 is rotatably connected to the telescopic rod 19, and a first spring 21 is sleeved on the slide groove surface of the telescopic rod 19. One end of the first spring 21 is fixedly connected to the rectangular plate 20, and the other end of the first spring 21 is fixedly connected to the left side of the slide groove of the telescopic rod 19.

[0029] In the present invention, when the rectangular plate 20 slides to the left, the first spring 21 is compressed, and the first spring 21 facilitates the rectangular plate 20 to be reset.

[0030] The left end surface of the telescopic rod 19 is fixedly connected with a strip plate 22, and the left side surface of the strip plate 22 is hinged with two push plates 23, and the left side surfaces of the two push plates 23 are hinged with friction plates 24. The outer parts of the two friction plates 24 are sleeved with a limit frame 25, and the two side surfaces of the limit frame 25 are provided with sliding holes, and the friction plates 24 are slidably connected with the sliding holes of the limit frame 25.

[0031] In the present invention, when the strip plate 22 is pushed to the left, the two push plates 23 will be pushed to rotate, and then under the limit of the limit frame 25, the two friction plates 24 will slide outward and contact the inner wall of the rotating circular cylinder 9, generating friction between them, so that the limit frame 25, friction plate 24, push plate 23, and strip plate 22 can rotate together with the circular cylinder 9.

[0032] The bottom surface of the rectangular plate 20 is hinged with an inclined plate 26, and the bottom surface of the inclined plate 26 is hinged with a sliding plate 27. A sealing cylinder 28 is fixedly connected to the bottom inner wall of the adaptive interference canceller box 3. The internal piston of the sealing cylinder 28 is connected to a first piston plate 29. The sealing cylinder 28 and the first piston plate 29 are fixedly filled with expandable gas. The top of the first piston plate 29 is fixedly connected to the sliding plate 27. The sliding plate 27 penetrates the sealing cylinder 28 and is slidably connected to the sealing cylinder 28.

[0033] In the present invention, when the surface of the heat dissipation window 5 is blocked by impurities such as dust and hair, the heat in the adaptive interference canceller box 3 cannot be discharged in time, and the internal temperature will gradually increase. At this time, the easily expandable gas in the sealing tube 28 expands under the action of thermal expansion, thereby pushing the first piston plate 29 to slide upward, and then pushing the sliding plate 27 to slide upward, through the inclined plate 26, and then pushing the rectangular plate 20 on the telescopic rod 19 to compress the first spring 21 to the left and slide, so that the telescopic rod 19 can be pulled to the left for a distance, pushing the strip plate 22 on the left, thereby pushing the two push plates 23 to push the friction plate 24 to the left, and finally following the rotation of the circular tube 9, so that the telescopic rod 19 rotates, and then drives the first rotating rod 10 to rotate, and finally controls the brush plate 15 to press the heat dissipation window 5 cleaning; after the heat dissipation window 5 is cleaned, the through holes on the surface are slowly opened, the heat in the adaptive interference canceller box 3 is gradually discharged, and the internal temperature will gradually return to normal. Therefore, under the effect of cold shrinkage, the easily expandable gas in the sealing tube 28 will no longer expand, so that the first piston plate 29 is lowered, and the sliding plate 27 is pulled downward, and the elastic force of the first spring 21 is assisted, so that the extended part of the telescopic rod 19 is reset, and the strip plate 22 and the two push plates 23 on the left are pulled, so that the friction plate 24 is contracted into the limit frame 25 and no longer contacts the inner wall of the circular tube 9, so that the telescopic rod 19 automatically stops rotating, and then the first rotating rod 10 also stops rotating, and then the external brush plate 15 is controlled to stop cleaning, and automatic control can be achieved without manual cleaning.

[0034] In some embodiments, a bearing plate 30 is fixedly connected to the bottom inner wall of the adaptive interference canceller box 3, a second rotating rod 31 is rotatably connected to the right side surface of the bearing plate 30, a protrusion 32 is fixedly connected to the right end surface of the second rotating rod 31, and a second synchronous belt 33 is transmission-connected between the second rotating rod 31 and the first rotating rod 10.

[0035] In the present invention, the second rotating rod 31 can be supported by the bearing plate 30. When the brush plate 15 slides and the telescopic rod 19 drives the first rotating rod 10 to rotate, the second rotating rod 31 is driven to rotate synchronously through the second synchronous belt 33, thereby driving the protrusion 32 to rotate simultaneously.

[0036] A piston cylinder 34 is fixedly connected to the inner wall of the adaptive interference canceller box 3, the internal piston of the piston cylinder 34 is connected to a second piston plate 35, a sliding rod 36 is fixedly connected to the inner surface of the second piston plate 35, the sliding rod 36 passes through the piston cylinder 34 and is slidably connected to the piston cylinder 34, a contact block 37 is fixedly connected to the surface of one end of the sliding rod 36 away from the second piston plate 35, and a second spring 38 is sleeved on the surface of the sliding rod 36.

[0037] One end of the second spring 38 is fixedly connected to the contact block 37, and the other end of the second spring 38 is fixedly connected to the piston cylinder 34. A water outlet hose 39 is fixedly connected between the piston cylinder 34 and the brush plate 15. The water outlet hose 39 passes through the adaptive interference canceller box 3 and is slidably connected to the adaptive interference canceller box 3. A detergent storage box 40 is fixedly installed on the bottom inner wall of the adaptive interference canceller box 3. A water suction pipe 41 is fixedly connected between the detergent storage box 40 and the piston cylinder 34, and a one-way valve is fixedly installed inside the water suction pipe 41 and the water outlet hose 39.

[0038] In the present invention, when the protrusion 32 rotates, when the protruding portion of the protrusion 32 rotates to conflict with the contact block 37, the contact block 37 will drive the sliding rod 36 to slide into the piston cylinder 34, and at the same time compress the second spring 38, thereby driving the second piston plate 35 to compress in the piston cylinder 34. Subsequently, when the protruding portion of the protrusion 32 does not conflict with the contact block 37, the second spring 38 automatically resets the contact block 37, the sliding rod 36 and the second piston plate 35. At the same time, the second piston plate 35 is reset and the detergent storage box 40 is sucked out through the water suction pipe 41. The detergent is absorbed and then squeezed out through the water outlet hose 39 and enters the brush plate 15, and is squeezed out reciprocally, so that the brush plate 15 can be assisted by the detergent to remove dirt while brushing, so that some stubborn dirt on the heat dissipation window 5 can be removed, and the surface of the heat dissipation window 5 can be cleaned more thoroughly; through the hose setting of the water outlet hose 39, it is convenient for the brush plate 15 to drive the water outlet hose 39 to slide, and through the one-way valve in the water outlet hose 39 and the water suction pipe 41, it can prevent water from being sucked in from the water outlet hose 39 when absorbing, and prevent it from being squeezed out from the water suction pipe 41 when squeezing.
