Description

Technical Field

[0001] The present invention relates to the technical field of satellite communication equipment, and specifically relates to a satellite communication device. Background Art

[0002] Satellite communication is the communication between radio communication stations on the earth (including the ground and the lower atmosphere) using satellites as relays, and the signal device is used to receive satellite signals and send them to other devices, usually installed on high-rise buildings.

[0003] Currently, in the prior art, due to the high installation position of the satellite communication device and few obstacles, the external environment has a great impact on the antenna of the satellite communication device. The antenna of the satellite communication device is exposed to the external environment for a long time and is vulnerable to rain erosion. At the same time, the antenna of the satellite communication device will also be attached with dust due to being exposed to the external environment for a long time, thereby affecting the signal reception strength of the antenna. In view of this, the present invention proposes a satellite communication device. Summary of the Invention

The protection mechanism includes:

[0007] A first elastic telescopic rod, the end of the telescopic end of the first elastic telescopic rod is fixedly connected to a connecting block;

[0008] A steel wire rope, one end of the steel wire rope is fixedly connected to the connecting block, and the other end of the steel wire rope is fixedly connected to a protective cover;

[0009] And a plurality of fixed pulleys, the steel wire rope is slidably connected to the fixed pulleys. By driving the connecting block to move upward through the first elastic telescopic rod, the steel wire rope moves, and the steel wire rope pulls the protective cover to open.

[0010] Preferably, the antenna mechanism includes an antenna housing, a slider is slidably connected to the inner wall of the antenna housing, the slider is fixedly connected to the output end of the electric telescopic rod, an installation block is fixedly connected to the upper side of the slider, an antenna rod is arranged on the top of the installation block, and the installation block and the antenna rod are elastically connected by a button spring.

[0011] Preferably, an elastic telescopic rod II is fixedly connected to the upper side of the slider. A fixing ring is fixedly connected to the telescopic end of the elastic telescopic rod II, and the fixing ring is fixedly connected to the inner wall of the antenna housing. A guiding strip is fixedly connected to the outer wall of the antenna rod. A round rod is slidably connected in the guiding strip. The round rod is hinged with a hinged rod, and one end of the hinged rod away from the guiding strip is hinged to the inner wall of the fixing ring. When the slider moves upward, it drives the mounting block to move upward, and the telescopic end of the elastic telescopic rod II is compressed. The round rod slides in the guiding strip. When the round rod slides to the bottom end of the guiding strip, the mounting block continues to move upward, and the hinged rod moves to drive the antenna rod to rotate.

[0012] Preferably, the elastic telescopic rod I is fixedly connected to the lower side of the slider. Multiple groups of fixed pulleys are dispersedly fixedly connected to the outer wall and the inner wall of the antenna housing. The protective cover and the top of the antenna housing are elastically connected by a button spring. When the protective cover is subjected to the pulling force of the steel cable, the two protective covers will compress the button spring to perform an opening movement. When the protective cover is no longer subjected to the pulling force of the steel cable, under the reset action of the button spring, it can drive the protective cover to reset, thereby closing the protective cover to protect the antenna rod, preventing the antenna rod from being eroded by rain in the external environment due to long-term exposure to the air, and also preventing a large amount of dust from adhering to the antenna rod, reducing the influence on the signal reception intensity of the antenna rod.

[0013] Preferably, multiple groups of the antenna rod, the guiding strip, the round rod and the hinged rod are provided. By pulling with multiple groups of hinged rods, multiple groups of antenna rods are unfolded.

[0014] Preferably, a trapezoidal block is fixedly connected to the outer wall of the telescopic end of the electric telescopic rod. Multiple groups of trapezoidal blocks are provided, and multiple groups of trapezoidal blocks are arranged in an equidistant array.

[0015] Preferably, a cleaning device is provided on the outer wall of the antenna housing. The cleaning device includes an air chamber. The air chamber is fixedly connected to the outer wall of the antenna housing. A one-way jet port and a one-way filter air inlet are opened on the outer wall of the air chamber. A piston is connected to a piston plate in the air chamber. By using the one-way filter air inlet, when the outside air is inhaled into the air chamber, the air will be filtered. The one-way jet port can eject the gas in the air chamber to clean the antenna rod and clean the dust attached to the antenna rod during the use of the device.

[0016] Preferably, a vertical rod is fixedly connected to the lower side of the piston plate. A return spring is sleeved on the outer surface of the vertical rod. Two ends of the return spring are respectively fixedly connected to the lower side of the piston plate and the inner surface of the air chamber.

[0017] Preferably, the vertical rod is hinged with a connecting rod. One end of the connecting rod away from the vertical rod is hinged with a cross rod. The cross rod penetrates through the outer wall of the antenna housing and is slidably connected to the outer wall of the antenna housing.

[0018] Preferably, a fixing block is fixedly connected to the outer wall of the cross bar. The fixing block and the inner wall of the antenna housing are elastically connected through a connecting spring. By moving the trapezoidal block upward to squeeze the cross bar, the cross bar moves away from the trapezoidal block, driving the connecting rod to move. The connecting rod pulls the vertical rod downward, causing the piston plate to slide in the air chamber.

[0019] The present invention provides a satellite communication device, which has the following beneficial effects:

[0020] (1) Through the use of the protection mechanism and the antenna mechanism, when the device needs to be used, by starting the electric telescopic rod, the antenna rod can extend from the antenna housing. During this process, the two protective covers open. When the device is not in use, the antenna rod can retract into the antenna housing. At the same time, the two protective covers close to protect the antenna rod, preventing the antenna rod from being eroded by rain in the external environment due to long-term exposure to the air, and also preventing a large amount of dust from adhering to the antenna rod, reducing the influence on the signal reception intensity of the antenna rod.

[0021] (2) Through the use of the protection mechanism, when the protective cover is opened to the maximum extent and the output end of the electric telescopic rod drives the slider to continue moving upward, the telescopic end of the elastic telescopic rod 1 is gradually stretched under the action of the steel wire rope, and thus it will not affect the slider's continued upward movement.

[0022] (3) Through the use of the antenna mechanism, after the antenna rod extends out of the antenna housing, when the round rod slides to the bottom end of the guide bar, the continued upward movement of the slider will cause the antenna rod to rotate under the action of the hinge rod, and multiple antenna rods will unfold, which can increase the signal range of the antenna. However, the relative antenna signal intensity decreases and the anti-interference ability decreases. During the process of the multiple antenna rods closing together, the signal range of the antenna shrinks, the antenna signal intensity increases, and the anti-interference ability increases, which is suitable for different external environments.

[0023] (4) Through the use of the cleaning device, when the antenna rod retracts back into the antenna housing after use, the one-way air jet port can eject gas to blow away the dust adhering to the antenna rod, reducing the dust adhering to the antenna rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The realization of the purpose, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9, the present invention provides a satellite communication device, which includes a fixing frame 1. The top of the fixing frame 1 is connected to a connecting frame 3. An electric telescopic rod 2 is fixedly connected to the outer wall of the connecting frame 3. An antenna mechanism 4 is arranged on one side of the connecting frame 3 away from the electric telescopic rod 2, and a protection mechanism 5 is arranged on the antenna mechanism 4.

[0038] In an embodiment of the present invention, in order to be applicable to different external environments, specifically, the antenna mechanism 4 includes an antenna housing 41. A slider 42 is slidably connected to the inner wall of the antenna housing 41. The slider 42 is fixedly connected to the output end of the electric telescopic rod 2. An installation block 44 is fixedly connected to the upper side of the slider 42. An antenna rod 46 is arranged on the top of the installation block 44, and the installation block 44 and the antenna rod 46 are elastically connected by a button spring. An elastic telescopic rod two 43 is fixedly connected to the upper side of the slider 42. A fixing ring 45 is fixedly connected to the telescopic end of the elastic telescopic rod two 43, and the fixing ring 45 is fixedly connected to the inner wall of the antenna housing 41. A guiding strip 47 is fixedly connected to the outer wall of the antenna rod 46. A round rod 48 is slidably connected in the guiding strip 47. The round rod 48 is hinged with a hinged rod 49, and one end of the hinged rod 49 away from the guiding strip 47 is hinged to the inner wall of the fixing ring 45. By the upward movement of the slider 42, the installation block 44 is driven to move upward, the telescopic end of the elastic telescopic rod two 43 is compressed, and the round rod 48 slides in the guiding strip 47. When the round rod 48 slides to the bottom end of the guiding strip 47, the installation block 44 continues to move upward, the hinged rod 49 moves, driving the antenna rod 46 to rotate, so that multiple groups of antenna rods 46 are unfolded, which can increase the signal range of the antenna, but the relative antenna signal strength decreases and the anti-interference ability decreases. During the process of the multiple groups of antenna rods 46 being closed together, the signal range of the antenna shrinks, the antenna signal strength increases, and the anti-interference ability increases, which is applicable to different external environments.

[0039] Further, in order to protect the antenna rod 46 and ensure the normal use of the device, specifically, the protection mechanism 5 includes a first elastic telescopic rod 51, a steel cable 53 and a fixed pulley 55. The end of the telescopic end of the first elastic telescopic rod 51 is fixedly connected with a connecting block 52. The first elastic telescopic rod 51 is fixedly connected to the lower side of the slider 42. One end of the steel cable 53 is fixedly connected with the connecting block 52, and the other end of the steel cable 53 is fixedly connected with a protective cover 54. The protective cover 54 is elastically connected to the top of the antenna housing 41 through a button spring. A plurality of groups of fixed pulleys 55 are provided, and the steel cable 53 is slidably connected to the fixed pulleys 55. The plurality of groups of fixed pulleys 55 are dispersedly and fixedly connected to the outer wall and the inner wall of the antenna housing 41. The output end of the electric telescopic rod 2 drives the slider 42 to rise, so that the first elastic telescopic rod 51 drives the connecting block 52 to move upward, so that the steel cable 53 moves, and the steel cable 53 pulls the protective cover 54 to open, so that the antenna rod 46 can extend out of the antenna housing 41. When the device is not in use, the output end of the electric telescopic rod 2 is reset, driving the slider 42 to descend. Then, the protective cover 54 rotates in place under the reset force of the button spring, so that the two protective covers 54 are closed, achieving the effect of protecting the antenna rod 46, preventing the antenna rod 46 from being eroded by rain in the external environment due to long-term exposure to the air, and also preventing a large amount of dust from adhering to the antenna rod 46, reducing the influence on the signal reception intensity of the antenna rod 46.

[0040] In an embodiment of the present invention, in order to further improve the cleanliness of the antenna rod 46 during use, specifically, a trapezoidal block 21 is fixedly connected to the outer wall of the telescopic end of the electric telescopic rod 2. A plurality of trapezoidal blocks 21 are provided, and the plurality of trapezoidal blocks 21 are arranged in an equidistant array. A cleaning device 6 is provided on the outer wall of the antenna housing 41. The cleaning device 6 includes an air chamber 61, and the air chamber 61 is fixedly connected to the outer wall of the antenna housing 41. A one-way jet port 62 and a one-way filtered air inlet 63 are formed on the outer wall of the air chamber 61. A piston is connected to a piston plate 64 in the air chamber 61. A vertical rod 65 is fixedly connected to the lower side of the piston plate 64. A return spring is sleeved on the outer surface of the vertical rod 65, and two ends of the return spring are respectively fixedly connected to the lower side of the piston plate 64 and the inner surface of the air chamber 61. The vertical rod 65 is hinged to a connecting rod 66, and one end of the connecting rod 66 away from the vertical rod 65 is hinged to a cross bar 67. The cross bar 67 penetrates through the outer wall of the antenna housing 41 and is slidably connected to the outer wall of the antenna housing 41. A fixing block 68 is fixedly connected to the outer wall of the cross bar 67. The fixing block 68 and the inner wall of the antenna housing 41 are elastically connected by a connecting spring. By driving the slider 42 to rise through the output end of the electric telescopic rod 2, the trapezoidal block 21 moves upward to squeeze the cross bar 67. Then, the cross bar 67 moves in a direction away from the trapezoidal block 21, driving the connecting rod 66 to move, so that the connecting rod 66 pulls the vertical rod 65 to move downward. Further, the piston plate 64 slides downward in the air chamber 61, sucking the outside air into the air chamber 61 from the one-way filtered air inlet 63, and the one-way filtered air inlet 63 filters the sucked air, filtering out dust and impurities. After the cross bar 67 passes through the trapezoidal block 21, under the reset action of the connecting spring and the return spring, the cross bar 67 is reset and the piston plate 64 is reset, and the gas in the air chamber 61 is ejected through the one-way jet port 62, realizing the cleaning of the antenna rod 46. Further, the antenna rod 46 can be cleaned once before and after use, achieving the effect of improving the cleanliness of the antenna rod 46 during use and ensuring the normal use of the device.

[0041] It should be noted that the above electrical components are all existing technical products. Those skilled in the art select, install and complete the circuit debugging operations according to the needs of use to ensure that each electrical appliance can work normally. The components are all common standard parts or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods, and no specific limitations are made here.

[0042] During use, first start the electric telescopic rod 2. The telescopic end of the electric telescopic rod 2 drives the slider 42 to rise, causing the elastic telescopic rod 1 51 to drive the connecting block 52 to move upward, making the steel cable 53 move. The steel cable 53 pulls the protective cover 54 to open, and then the antenna rod 46 can extend out of the antenna housing 41. During this process, the mounting block 44 moves upward, and the telescopic end of the elastic telescopic rod 2 43 is compressed. The round rod 48 slides within the guide bar 47. When the round rod 48 slides to the bottom end of the guide bar 47, the mounting block 44 continues to move upward, and the articulated rod 49 moves, driving the antenna rod 46 to rotate, causing multiple groups of antenna rods 46 to unfold, which can increase the signal range of the antenna, but the relative antenna signal strength decreases and the anti-interference ability decreases. During the process of multiple groups of antenna rods 46 closing together, the signal range of the antenna contracts, the antenna signal strength increases, and the anti-interference ability increases;

[0043] Meanwhile, during the process of the output end of the electric telescopic rod 2 driving the slider 42 to rise, the elastic telescopic rod 1 51 drives the connecting block 52 to move upward, making the steel cable 53 move. The steel cable 53 pulls the protective cover 54 to open, and then the antenna rod 46 can extend out of the antenna housing 41. When the device is not in use, start the output end of the electric telescopic rod 2 to reset, driving the slider 42 to descend. The protective cover 54 rotates for reset under the reset force of the button spring, closing the two groups of protective covers 54 to achieve the protection of the antenna rod 46;

[0044] Meanwhile, during the process of the output end of the electric telescopic rod 2 driving the slider 42 to rise, the trapezoidal block 21 moves upward and squeezes the cross bar 67. Then the cross bar 67 moves in the direction away from the trapezoidal block 21, driving the connecting rod 66 to move, causing the connecting rod 66 to pull the vertical rod 65 to move downward. Then the piston plate 64 slides downward in the air chamber 61, sucking the outside air into the air chamber 61 from the one-way filtering air inlet 63. And the one-way filtering air inlet 63 filters the inhaled air, filtering out dust and impurities. After the cross bar 67 passes through the trapezoidal block 21, under the reset action of the connecting spring and the reset spring, the cross bar 67 is reset, and the piston plate 64 is reset, spraying the gas in the air chamber 61 through the one-way jet port 62 to achieve the cleaning of the antenna rod 46. Then the antenna rod 46 can be cleaned once before and after use.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
