[0042] 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.

[0044] Reference Figure 1-Figure 9 , a phased array antenna for satellite communication, comprising a phased array antenna body 1, and further comprising:

[0051] Among them, the protection mechanism 3 includes a protection shell 31 fixed on the top of the supporting leg 2, the phased array antenna body 1 is detachably installed in the protection shell 31, a ventilation slot 32 is opened on the top of the protection shell 31, and a side cover 33 is hinged on the front of the protection shell 31 through a hinge, and dust nets are fixed in the side cover 33 and the ventilation slot 32.

[0052] The water collecting mechanism 4 comprises a rain collecting box 41 fixed on the back of the protective shell 31 , and the outer surface of the rain collecting box 41 is connected to a water collecting tank 42 .

[0053] Among them, the pumping mechanism 5 includes an installation box 51 fixed on the top of the protective shell 31, and a rotating rod 52 is rotated on the inner wall of the installation box 51 through a bearing. An impeller 53 is fixed to the left end of the rotating rod 52, and a turntable 54 is fixed to the end of the rotating rod 52 away from the impeller 53. A push rod 55 is fixed to the front side of the turntable 54, and the push rod 55 slides in the moving shell 56. Moving rods 57 are fixed on both side surfaces of the moving shell 56. The moving rod 57 is slidably connected to the inner wall of the installation box 51, and a piston cylinder 58 is fixed to the back of the installation box 51, and a piston disk 59 is fixed to one end of one of the moving rods 57, and the piston disk 59 moves in the piston cylinder 58.

[0054] Among them, the pumping mechanism 5 also includes a water inlet pipe 510 and a water outlet pipe 511 connected to the outer surface of the piston cylinder 58, a water inlet valve 512 is arranged at the connection between the water inlet pipe 510 and the piston cylinder 58 through a rotating shaft, a water outlet valve 513 is arranged at the connection between the water outlet pipe 511 and the piston cylinder 58 through a rotating shaft, a block 5131 is fixed in the water outlet pipe 511 for preventing the water outlet valve 513 from turning over, one end of the water inlet pipe 510 is connected to the rain collecting box 41 through a hose 1 514, a water cooling pipe 515 is fixed in the protective shell 31, one end of the water outlet pipe 511 is connected to the water cooling pipe 515 through a hose 2 516, and the other end of the water cooling pipe 515 is connected to the rain collecting box 41 through a hose 3 517.

[0055] The water cooling tube 515 is fitted to the top of the phased array antenna body 1 and is arranged in a "U" shape.

[0056] In a preferred embodiment, the water collecting trough 42 and the rain collecting box 41 are arranged on the protective shell 31. When it rains, rain falls into the water collecting trough 42 and flows from the water collecting trough 42 into the rain collecting box 41. The rain collecting box 41 is used to collect rain. When the vehicle is driving, the phased array antenna body 1 can be cooled by wind. The impeller 53 is set so that the impeller 53 rotates under the influence of the wind. The rotation of the impeller 53 drives the rotating rod 52 and the rotating disk 54 to rotate. The rotating disk 54 drives the rotating rod 52 and the rotating disk 54 to rotate. The push rod 55 is driven to rotate, and the push rod 55 can slide in the moving shell 56 and the moving rod 57 can slide on the inner wall of the installation box 51, thereby driving the moving shell 56 and the moving rod 57 to reciprocate horizontally. Since the moving rod 57 is connected to the piston plate 59, the piston plate 59 is driven to move in the piston cylinder 58. When the piston plate 59 moves upward, the pressure generated drives the water inlet valve 512 to flip upward counterclockwise, so that the opening of the water inlet pipe 510 is opened. Since the water inlet pipe 510 is connected to the collecting pipe through the hose 514, the water inlet valve 512 is driven to rotate counterclockwise, so that the water inlet pipe 510 is opened. When the rain box 41 is connected, the rainwater in the rain collecting box 41 will be drawn into the piston cylinder 58. At the same time, when the piston disc 59 moves upward, the pressure generated will drive the water outlet valve 513 to rotate downward clockwise. The setting of the stopper 5131 will block the turning of the water outlet valve 513, so that the opening of the water outlet pipe 511 is closed. At this time, rainwater will enter the piston cylinder 58 from the water inlet pipe 510, but will not flow out from the water outlet pipe 511. Similarly, when the piston disc 59 moves downward, the water inlet valve 512 will close the opening of the water inlet pipe 510, and the water outlet valve 513 will close the water outlet pipe 511. 513 will open the opening of the water outlet pipe 511, so that rainwater enters the water cooling pipe 515 from the water outlet pipe 511 and the hose two 516, and then flows back into the rain collecting box 41 from the water cooling pipe 515 and the hose three 517, so that the rainwater forms a reflux channel in the water cooling pipe 515. The water cooling pipe 515 fits the phased array antenna body 1, and the flowing rainwater forms water cooling to dissipate the heat of the phased array antenna body 1 again. The "U" design of the water cooling pipe 515 increases the contact area between the water cooling pipe 515 and the phased array antenna body 1, thereby improving the heat dissipation effect.

[0057] By adopting this technical solution, the collected rainwater can be pumped out during the driving of the car, and the wind power can be used to pump out the rainwater collected in the water collection mechanism 4. The phased array antenna body 1 is cooled by a combination of air cooling and water cooling, which has a better heat dissipation effect. The collected rainwater is used to dissipate heat, which reduces the waste of water resources.

[0058] In a preferred embodiment, by setting the supporting legs 2, when the phased array antenna body 1 is installed, a certain gap can be maintained between the phased array antenna body 1 and the ground. By setting the protective shell 31, the phased array antenna body 1 can be installed in the protective shell 31, which can provide certain protection for the phased array antenna body 1. In combination with the setting of the dustproof net, sand and stones can be prevented from entering the protective shell 31 to cause damage to the phased array antenna body 1 while allowing heat to be dissipated.

[0059] By adopting this technical solution, the gap between the phased array antenna body 1 and the vehicle body is used to avoid the bottom cover of the phased array antenna body 1 from fitting with the vehicle body, making it difficult to clean the connection, while improving the protection performance of the phased array antenna body 1.

[0060] Reference Figure 1-Figure 9 , a phased array antenna for satellite communication, comprising a phased array antenna body 1, and further comprising:

[0061] A support leg 2 is arranged below the phased array antenna body 1, and the support leg 2 is used to leave a gap between the phased array antenna body 1 and the vehicle body to facilitate cleaning of the connection therebetween;

[0062] A protection mechanism 3 is located on the outer surface of the phased array antenna body 1, and the protection mechanism 3 is used to block sand and stones;

[0063] A water collection mechanism 4 is arranged on the protection mechanism 3, and the water collection mechanism 4 is used to collect rainwater;

[0064] A pumping mechanism 5 installed on the protection mechanism 3, the pumping mechanism 5 is used to extract rainwater and cooperate with air cooling to assist heat dissipation;

[0065] A cleaning mechanism 6 is arranged at the bottom of the protection mechanism 3, and the cleaning mechanism 6 is used to clean the connection between the phased array antenna body 1 and the vehicle body;

[0066] The swing mechanism 7 is arranged on the supporting leg 2, and the swing mechanism 7 is used to increase the cleaning range of the cleaning mechanism 6.

[0067] Among them, the cleaning mechanism 6 includes a rectangular box 61 fixed at the bottom of the protective shell 31, an air bag 62 is fixed on the bottom wall of the rectangular box 61, an air nozzle 63 is fixed at the center of the air bag 62, the top of the air nozzle 63 is connected to a connecting pipe 64, the outer surface of the piston cylinder 58 is connected to an air intake hose 65, and the other end of the air intake hose 65 is connected to the connecting pipe 64.

[0068] In a preferred embodiment, a rectangular box 61 is fixed to the bottom of the protective shell 31 so that there is a gap between the air nozzle 63 and the vehicle body, so that the gas blown out of the air nozzle 63 can be blown to the top of the vehicle body, and is connected with the connecting pipe 64 through the air intake hose 65. When the piston disc 59 moves upward, the gas in the piston cylinder 58 is squeezed, so that the squeezed gas enters the connecting pipe 64 from the air intake hose 65, and then enters the air nozzle 63 from the connecting pipe 64. The gas is intermittently ejected from the air nozzle 63 to blow away dust and sand, and the part of the phased array antenna body 1 covering the vehicle body can be cleaned while the vehicle is driving.

[0069] By adopting this technical solution, the piston disk 59 can be intermittently moved by wind to extract the collected rainwater to dissipate the heat of the phased array antenna body 1. At the same time, the movement of the piston disk 59 in the piston cylinder 58 can be used to simultaneously clean the part of the phased array antenna body 1 covering the vehicle body, making it more convenient for users to clean the roof later.

[0070] Reference Figure 1-Figure 9 , a phased array antenna for satellite communication, comprising a phased array antenna body 1, and further comprising:

[0071] A support leg 2 is arranged below the phased array antenna body 1, and the support leg 2 is used to leave a gap between the phased array antenna body 1 and the vehicle body to facilitate cleaning of the connection therebetween;

[0072] A protection mechanism 3 is located on the outer surface of the phased array antenna body 1, and the protection mechanism 3 is used to block sand and stones;

[0073] A water collection mechanism 4 is arranged on the protection mechanism 3, and the water collection mechanism 4 is used to collect rainwater;

[0074] A pumping mechanism 5 installed on the protection mechanism 3, the pumping mechanism 5 is used to extract rainwater and cooperate with air cooling to assist heat dissipation;

[0075] A cleaning mechanism 6 is arranged at the bottom of the protection mechanism 3, and the cleaning mechanism 6 is used to clean the connection between the phased array antenna body 1 and the vehicle body;

[0076] The swing mechanism 7 is arranged on the supporting leg 2, and the swing mechanism 7 is used to increase the cleaning range of the cleaning mechanism 6.

[0077] Among them, the swing mechanism 7 includes a connecting rod 71 fixed on the outer surface of another moving rod 57, a rack 72 is fixed to the bottom end of the connecting rod 71, a circular gear 73 is meshed on the outer surface of the rack 72, a rotating rod 74 is fixed at the axis of the circular gear 73, the rotating rod 74 is rotatably connected to the support leg 2 through a bearing, and a cam 75 is fixed at one end of the rotating rod 74.

[0078] Among them, the swing mechanism 7 also includes a telescopic rod 76 fixed to the front side of the rectangular box 61, one end of the telescopic rod 76 is fixed with an extrusion plate 77, the extrusion plate 77 corresponds to the position of the cam 75, and one side of the extrusion plate 77 is fixed with a slide bar 78, one end of the slide bar 78 slides through the inner wall of the rectangular box 61 and is fixed to the connecting tube 64, and the outer surface of the telescopic rod 76 is sleeved with a return spring 79, and the two ends of the return spring 79 are respectively connected to the rectangular box 61 and the extrusion plate 77.

[0079] In a preferred embodiment, the airbag 62 is fixed to the bottom wall of the rectangular box 61 and the slide bar 78 is connected to the center of the airbag 62. The elastic force of the airbag 62 can be used to prevent the air nozzle 63 from being in a fixed state, so that the air nozzle 63 can swing under force. The airbag 62 is connected to one of the moving rods 57 through the connecting rod 71. When the wind drives the impeller 53 to rotate and drives the moving rod 57 to move left and right, the connecting rod 71 can be driven to move together synchronously. The connecting rod 71 is connected to the rack 72 and drives the rack 72 to move together. The rack 72 drives the circular gear 73 to rotate, and the circular gear 73 drives the rotating rod 2 74 and the cam 75 to rotate. Since the position of the cam 75 and the extrusion plate 77 is relatively close, the connecting rod 71 can be driven to move together. Correspondingly, when the raised end of the cam 75 contacts the extrusion plate 77, the extrusion plate 77 is squeezed, and the extrusion plate 77 squeezes the telescopic rod 76 and the return spring 79, and slides in the inner wall of the rectangular box 61 through the slide bar 78, thereby driving the slide bar 78 to slide to the right. The slide bar 78 is connected to the connecting tube 64, and through the elastic force of the airbag 62, it can drive the connecting tube 64 and the air nozzle 63 to swing. When the raised end of the cam 75 is away from the extrusion plate 77, the elastic force of the return spring 79 can drive the extrusion plate 77 and the connecting tube 64 to reset, so that the air nozzle 63 can swing left and right. When the gas is blown out from the air nozzle 63, the blowing range of the air nozzle 63 can be increased, further improving its cleaning effect.

[0080] By adopting such a technical solution, the impeller 53 is driven to rotate by wind power. In addition to being able to extract rainwater for heat dissipation, the air bag 62 can also be simultaneously swung when blowing sand and gravel, further improving the blowing effect of the air nozzle 63.

[0081] Working principle: When in use, the support leg 2 is fixed to the top of the vehicle body by bolts, and the phased array antenna body 1 is fixed in the protective shell 31, and rainwater can flow into the rain collecting box 41 through the water collecting trough 42 to collect rainwater. When the car is driving, the impeller 53 rotates due to the influence of wind force, and the impeller 53 drives the rotating rod 1 52 and the rotating disk 54 to rotate, and the rotating disk 54 drives the pushing rod 55 to rotate, thereby driving the moving shell 56 and the moving rod 57 to reciprocate left and right in the horizontal direction, thereby driving the piston plate 59 to move in the piston cylinder 58. When the piston plate 59 moves upward, the pressure generated drives the water inlet valve 512 to flip upward counterclockwise, so that the opening of the water inlet pipe 510 is opened. Since the water inlet pipe 510 is connected to the rain collecting box 41 through the hose 1 514, the rainwater in the rain collecting box 41 is pumped into the piston cylinder 58. At the same time, When the piston disc 59 moves upward, the pressure generated will drive the water outlet valve 513 to flip downward clockwise, and the water outlet valve 513 is blocked by the block 5131 and stops, thereby closing the opening of the water outlet pipe 511. At this time, rainwater will enter the piston cylinder 58 from the water inlet pipe 510, but will not flow out from the water outlet pipe 511. Similarly, when the piston disc 59 moves downward, the water inlet valve 512 will close the opening of the water inlet pipe 510, and the water outlet valve 513 will open the opening of the water outlet pipe 511, so that rainwater enters the water cooling pipe 515 from the water outlet pipe 511 and the second hose 516, and then flows back into the rain collecting box 41 from the water cooling pipe 515 and the third hose 517, so that the rainwater forms a reflux channel in the water cooling pipe 515, and the water cooling pipe 515 fits the phased array antenna body 1, and the phased array antenna body 1 is cooled again by the flowing rainwater.

[0082] 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.
