Description

Technical Field

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

[0002] A satellite antenna, commonly known as a large dish, is a metal parabolic surface that is responsible for reflecting satellite signals into the feed and low-noise block downconverter (LNB) located at the focal point. The function of a satellite antenna is to collect weak signals transmitted by satellites and remove as much noise as possible. Most antennas are usually parabolic in shape, and some multi-focus antennas are composed of a combination of a spherical surface and a parabolic surface.

[0003] Chinese Patent Application No. 2023208193844 discloses a satellite antenna, including an antenna main body and a support base plate. A hydraulic inner rod is installed below the antenna main body, and a hydraulic outer rod is installed at the bottom of the hydraulic inner rod. A connecting plate is installed on the outer side of the hydraulic inner rod, and a first rotating shaft is installed at the middle position of the connecting plate. An inner support rod is installed below the first rotating shaft, and an outer support rod is installed below the inner support rod. The support base plate is installed at the bottom of the outer support rod, and a second rotating shaft is arranged below the support base plate. A mounting frame is installed at the middle position of the second rotating shaft, and a mounting plate is installed at the bottom of the mounting frame. And a plug rod is arranged at the bottom of the mounting plate. A limiting plate is installed on the outer wall of the hydraulic outer rod; the utility model is convenient for folding during transportation, occupies less space during transportation, reduces transportation costs, and can improve the placement stability of the antenna main body, so that it is in a stable state during operation.

[0004] The circular cover on the above satellite antenna is an integrated structure. Although the integrated structure has strong stability, there are the following deficiencies: First, the satellite antenna needs to be installed on the top of a building or at a higher place, and it will encounter strong wind currents. When the wind is strong, the strong wind current is likely to overturn the satellite antenna, resulting in the satellite antenna being unusable. Second, in snowy weather, snowflakes will continuously fall and accumulate on the circular cover, easily crushing the circular cover. Therefore, we propose a Beidou satellite antenna. Summary of the Invention

[0005] The purpose of the present invention is to provide a Beidou satellite antenna for the deficiencies of the prior art.

[0039] Embodiment 1: As Figures 1 - 12 shown, this embodiment provides a Beidou satellite antenna, which includes a bearing mechanism 1, a side lobe mechanism 2 installed on the bearing mechanism 1, and an antenna body 3 installed on the side lobe mechanism 2. The bearing mechanism 1 includes a fixed seat 100, a rotating table 101 rotatably installed on the fixed seat 100, a mounting seat 102 installed on the rotating table 101, a first rotary driving member 103 installed on the mounting seat 102, a U-shaped frame 104 installed at the output end of the first rotary driving member 103, a protective cover 201 installed on the U-shaped frame 104, and the rotation of the rotating table 101 is driven by a motor.

[0040] The side lobe mechanism 2 includes: a protective cover 201; a rotating rod 202 rotatably arranged in the protective cover 201; a connecting plate a 203 installed on the rotating rod 202; a plurality of side lobes a 204 installed on the connecting plate a 203; a rotating sleeve 205 sleeved outside the rotating rod 202; a connecting plate b 206 installed on the rotating sleeve 205; a plurality of side lobes b 207 installed on the connecting plate b 206; and a driving assembly 21 arranged in the protective cover 201.

[0041] The driving component 21 includes a linear driving member a211 installed inside the protective cover 201 and a fixed plate 213. A moving ring 212 is installed at the output end of the linear driving member a211, and the moving ring 212 is sleeved outside the rotating rod 202. A rotary driving member a214 is installed on the fixed plate 213, and a gear a215 is installed at the output end of the rotary driving member a214. A gear b216 is rotatably arranged on the fixed plate 213. The gear a215 and the gear b216 are meshed. A chute 2161 is formed inside the gear b216, and the rotating rod 202 slides in the chute 2161. It should be noted that: a T-shaped ring groove (not shown in the figure) is formed inside the moving ring 212, and a T-shaped ring block (not shown in the figure) is installed on the rotating rod 202, and the T-shaped ring block rotates in the T-shaped ring groove.

[0042] A third rotary driving member 217 is installed on the fixed plate 213, and a third gear 218 is installed at the output end of the third rotary driving member 217.

A groove 2162 is formed inside the gear b216, and the convex block 2023 slides in the groove 2162.

[0043] In this embodiment, the circular cover is assembled by a plurality of side flaps a204 and a plurality of side flaps b207. When encountering strong wind currents, the linear driving member a211 drives the moving ring 212 to move upward, driving the rotating rod 202, the connecting plate a203, and the side flap a204 to move upward. At this time, the side flap a204 and the side flap b207 are staggered and not aligned. Then, the rotary driving member a214 drives the gear a215 to rotate, driving the gear b216 and the rotating rod 202 to rotate, driving the side flap a204 to move above the side flap b207. The linear driving member a211 drives the side flap a204 to move so that it is close to and aligned with the side flap b207. At this time, the side flap a204 is stacked on the side flap b207 (the state is as Figure 7 shown); the strong wind current passes through the gap on the side of the side flap a204 and the side flap b207, greatly reducing the possibility of the satellite antenna being overturned.

[0044] When encountering snowy weather, the linear driving member a211 drives the moving ring 212 to move upward, driving the rotating rod 202, the connecting plate a203, and the side flap a204 to move upward. At this time, the side flap a204 and the side flap b207 are staggered and not aligned. Then, the rotary driving member a214 drives the gear a215 to rotate, driving the gear b216 and the rotating rod 202 to rotate, driving the side flap a204 to move above the side flap b207. The linear driving member a211 drives the side flap a204 to move so that it is close to and aligned with the side flap b207. At this time, the side flap a204 is stacked on the side flap b207 (the state is as Figure 7 shown); at this time, the accumulated rain and snow fall along the gap on the side of the side flap a204 and the side flap b207, greatly reducing the possibility of the satellite antenna being damaged by pressure.

[0045] Example 2: As Figures 1 - 12 shown, the components that are the same as or corresponding to those in Example 1 are labeled with the corresponding reference numerals in Example 1. For the sake of simplicity, only the differences from Example 1 will be described below. The difference between this Example 2 and Example 1 is that:

[0046] This example further includes a water collection mechanism 4, and the water collection mechanism 4 includes: a water collection hole 400, which is opened in the connecting plate a 203 and the connecting plate b 206; a collection cover 401, which is installed below the connecting plate b 206; a water storage tank 402, which is provided on one side of the fixed seat 100; a return pipe 403, through which the collection cover 401 and the water storage tank 402 are connected; a heating assembly 41, which is provided on the water storage tank 402.

[0047] The heating assembly 41 includes: a water inlet pipe 411, which is provided at one end of the water storage tank 402 and the rotating rod 202; a drain pipe 412, which is provided at one end of the water storage tank 402 and the rotating rod 202; an inflow groove 2021 and an outflow groove 2022 are opened in the rotating rod 202; a flow groove 410 is opened in the side lobe a 204, and the water inlet pipe 411, the inflow groove 2021, the flow groove 410, the outflow groove 2022, and the drain pipe 412 are connected; a black heating tape 413, which is provided on the side lobe a 204, and the positions of the black heating tape 413 and the flow groove 410 correspond.

[0048] In this example, in rainy weather, the first rotation driving member 103 drives the side lobe mechanism 2 to rotate upward. At this time, rainwater falls on the side lobe mechanism 2, and the rainwater falls into the collection cover 401 along the water collection hole 400 and flows into the water storage tank 402 through the return pipe 403 for storage;

[0049] When it is sunny, the water flow in the water storage tank 402 is pumped into the water inlet pipe 411 through a power pump (a conventional technical means in this field). The water flow flows back to the water storage tank 402 along the inflow groove 2021, the flow groove 410, the outflow groove 2022, and the drain pipe 412. The black heating tape 413 absorbs sunlight to heat the water flow in the flow groove 410, so that the heated water flow is returned to the water storage tank 402. The water storage tank 402 is provided with heat insulation cotton to keep the hot water warm, and a heating block can also be provided in the water storage tank 402 to keep the hot water warm.

[0050] Example 3: As Figures 1 - 12 shown, the components that are the same as or corresponding to those in Example 1 are labeled with the corresponding reference numerals in Example 1. For the sake of simplicity, only the differences from Example 1 will be described below. The difference between this Example 3 and Example 1 is that:

[0051] This embodiment further includes a support mechanism 5, and the support mechanism 5 supports the antenna body 3. The support mechanism 5 includes a fixed rod 501, the fixed rod 501 is arranged inside the rotating rod 202, and the antenna body 3 is installed at the top of the fixed rod 501; a connecting seat 502 is installed on the fixed rod 501, two avoidance grooves 5021 are formed in the connecting seat 502, a swing arm 503 is rotatably arranged in the avoidance groove 5021, and a support rod 504 is slidably arranged in the swing arm 503.

[0052] A rotating shaft 505 is installed on the swing arm 503, a fifth gear 506 is installed on the rotating shaft 505, two rack plates 507 are arranged in the connecting seat 502, and the rack plates 507 and the fifth gear 506 are meshed; a fourth rotation driving member 508 is installed in the connecting seat 502, a sixth gear 509 is installed at the output end of the fourth rotation driving member 508, and the sixth gear 509 and the fifth gear 506 are meshed.

[0053] A sliding groove 5031 and a receiving cavity 5032 are formed in the swing arm 503, a T-shaped slide bar a510 and a slide bar b511 are installed in the support rod 504, and the T-shaped slide bar a510 slides in the sliding groove 5031;

[0054] The slide bar b511 slides in the receiving cavity 5032, a water pipe a512 is arranged at one end of the rotating shaft 505, the water pipe a512 is communicated with the slide bar b511, a water spraying hole 5041 and a flow cavity 5042 are formed in the support rod 504, and a water pipe b513 is installed at the other end of the rotating shaft 505, and the water pipe b513 is communicated with the sliding groove 5031.

[0055] In this embodiment, the fourth rotation driving member 508 drives the sixth gear 509 to rotate, drives the rack plate 507 to move, drives the fifth gear 506 and the swing arm 503 to rotate, and the water pump pumps the water flow in the water storage tank 402 through the water pipe b513 to the sliding groove 5031, drives the support rod 504 to extend outwards to support the side lobe a204 and the side lobe b207. It should be noted that: one end of the water pipe b513 is communicated with the sliding groove 5031, and the other end thereof passes through the fixed rod 501 and is communicated with the water storage tank 402. Preferably, two water pumps are provided, one pumps water flow forward and the other pumps water flow in the reverse direction (cooperating with valves), which is a conventional technical means in this field and will not be described in detail here.

[0056] In this embodiment, the water pump pumps the water flow in the water storage tank 402 through the water pipe a512 and the flow cavity 5042 to be sprayed out from the water spraying hole 5041 to clean the side lobe a204 and the side lobe b207. At the same time, when it is rainy or snowy, the side lobe a204 and the side lobe b207 are frozen. The water pump pumps the hot water in the water storage tank 402 through the water pipe a512 and the flow cavity 5042 to be sprayed out from the water spraying hole 5041 to melt the ice on the side lobe a204 and the side lobe b207.

[0057] Working steps

[0058] Step 1, reduce overturning: the circular cover in this embodiment is assembled by multiple side flaps a204 and multiple side flaps b207. When encountering strong wind flow, the linear drive member a211 drives the motion ring 212 to move upward, driving the rotating rod 202, the connecting plate a203, and the side flap a204 to move upward. At this time, the side flap a204 is misaligned with the side flap b207. Then the rotating drive member a214 drives the gear a215 to rotate, driving the gear b216 and the rotating rod 202 to rotate, driving the side flap a204 to move above the side flap b207, and the linear drive member a211 drives the side flap a204 to move so that it is close to and aligned with the side flap b207. At this time, the side flap a204 is piled on the side flap b207 (the state is as shown in FIG. Figure 7 Strong wind flows along the gaps on the sides of the side lobes a204 and b207, greatly reducing the possibility of the satellite antenna flipping over;

[0059] Step 2: Reduce the accumulation of rain and snow: When it snows, the linear drive member a211 drives the motion ring 212 to move upward, driving the rotating rod 202, the connecting plate a203, and the side flap a204 to move upward. At this time, the side flap a204 is misaligned with the side flap b207. Then the rotating drive member a214 drives the gear a215 to rotate, driving the gear b216 and the rotating rod 202 to rotate, driving the side flap a204 to move above the side flap b207. The linear drive member a211 drives the side flap a204 to move so that it is close to and aligned with the side flap b207. At this time, the side flap a204 is piled on the side flap b207 (the state is as shown in FIG. 1 ). Figure 7 shown);

[0060] The accumulated rain and snow fall along the gaps on the sides of the side lobes a204 and b207, greatly reducing the possibility of the satellite antenna being crushed;

[0061] Step 3, water collection and heating process: in rainy weather, the first rotary drive member 103 drives the side flap mechanism 2 to rotate upward, and rainwater falls on the side flap mechanism 2, and falls into the collection cover 401 along the water collection hole 400, and flows through the return pipe 403 to the water storage tank 402 for storage;

[0062] On sunny days, the water in the water tank 402 is pumped into the water inlet pipe 411 by a power pump (a conventional technical means in the art), and the water flows back to the water tank 402 along the inflow groove 2021, the flow groove 410, the outflow groove 2022, and the drain pipe 412. The black heating belt 413 absorbs sunlight to heat the water in the flow groove 410, so that the heated water flows back to the water tank 402. The water tank 402 is provided with heat insulation cotton to keep the hot water warm.

[0063] Step Four: Support Process: The fourth rotary drive 508 drives the sixth gear 509 to rotate, driving the rack plate 507 to move, driving the fifth gear 506 and the swing arm 503 to rotate. The pump draws the water flow in the water storage tank 402 through the water pipe b513 into the sliding groove 5031, and drives the support rod 504 to extend outwards to support the side lobe a204 and the side lobe b207.

[0064] Step Five: Cleaning Process: The pump draws the water flow in the water storage tank 402 through the water pipe a512 and the flow cavity 5042 to be sprayed out from the spray holes 5041 to clean the side lobe a204 and the side lobe b207. At the same time, when it is rainy or snowy, the side lobe a204 and the side lobe b207 are frozen. The pump draws the hot water in the water storage tank 402 through the water pipe a512 and the flow cavity 5042 to be sprayed out from the spray holes 5041 to melt the ice on the side lobe a204 and the side lobe b207.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
