DETAILED DESCRIPTION

[0032] 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.

[0034] Reference Figure 1-Figure 13 A satellite antenna for mobile communication comprises a bottom support frame 1 and a parabolic antenna 2 rotatably arranged above the bottom support frame 1, a feed rod 3 is fixedly mounted on the parabolic antenna 2, a mounting tube 4 is fixedly connected to the back surface of the parabolic antenna 2, a dual-axis motor 5 is fixedly connected to the right inner wall of the mounting tube 4, and further comprises: a first rotating rod 6, fixedly connected to the left output end of the dual-axis motor 5; a mounting block 7, fixedly connected to the left end surface of the first rotating rod 6, a soft water-absorbing scraper 8 is fixedly connected to the surface of the mounting block 7; a hard scraper 9, hinged to the surface of the mounting block 7, a connecting plate 10 is fixedly connected to the top surface of the hard scraper 9, a baffle 11 is fixedly connected to the side surface of the connecting plate 10, and a resisting plate 12 is hinged to the top surface of the connecting plate 10.

[0035] In the present invention, when dust and rainwater accumulate in the parabolic antenna 2, the staff installs the mounting block 7 and the soft water-absorbing scraper 8 and the hard scraper 9 on the surface between the first rotating rod 6, and then adjusts the parabolic antenna 2 to a vertical state with the ground or aligned with the ground, and then starts the dual-axis motor 5 to drive the first rotating rod 6 to rotate, thereby driving the soft water-absorbing scraper 8 and the hard scraper 9 to rotate at the same time, and scraping the rainwater and dust and other impurities on the inner wall of the parabolic antenna 2, thereby effectively scraping off the dust and accumulated water and other impurities in the parabolic antenna 2, reducing the adsorption of dust and rainwater on the parabolic antenna 2, and no manual cleaning is required, which can improve the stability of communication of the satellite antenna and enable the antenna to receive satellite signals more accurately.

[0036] Reference Figure 1-Figure 12 In some embodiments, the feed rod 3 is provided with three groups, the first rotating rod 6 passes through the parabolic antenna 2 and is rotatably connected to the parabolic antenna 2, the soft water-absorbing scraper 8 is slidably connected to the inner wall of the parabolic antenna 2, the hard scraper 9 is slidably connected to the inner wall of the parabolic antenna 2, and a torsion spring 15 is fixedly connected between the contact plate 12 and the connecting plate 10.

[0037] A connecting rod 13 is fixedly connected between the hard scraper 9 and the soft water-absorbing scraper 8. A first spring 14 is sleeved on the surface of the connecting rod 13. One end of the first spring 14 is fixedly connected to the soft water-absorbing scraper 8, and the other end of the first spring 14 is fixedly connected to the hard scraper 9.

[0038] In the present invention, the elastic force of the first spring 14 is smaller than the torsion force of the torsion spring 15. When the soft water-absorbing scraper 8 scrapes the parabolic antenna 2, the soft water-absorbing scraper 8 absorbs the accumulated water. When the hard scraper 9 drives the top connecting plate 10 and the contact plate 12 to rotate with the soft water-absorbing scraper 8, the contact plate 12 contacts the feed rod 3. Then the contact plate 12 drives the hard scraper 9 to contact and fit with the soft water-absorbing scraper 8 by compressing the first spring 14 to squeeze the soft water-absorbing scraper 8, and the accumulated water absorbed by the soft water-absorbing scraper 8 is removed. After being squeezed out and falling off, the contact plate 12 is then rotated by compressing the torsion spring 15, disengaged from the feed rod 3, and then again contacts with the next feed rod 3, and performs such a reciprocating operation, so that the soft water-absorbing scraper 8 can clear the accumulated water and dust from the parabolic antenna 2 while squeezing out the accumulated water, thereby accelerating the speed at which the accumulated water and dust in the parabolic antenna 2 fall off; through the first spring 14, after the hard scraper 9 contacts and squeezes the soft water-absorbing scraper 8, when the contact plate 12 is disengaged from the feed rod 3, the hard scraper 9 is automatically reset.

[0039] The right output end of the dual-axis motor 5 is fixedly connected with a second rotating rod 16 , the right end surface of the second rotating rod 16 is fixedly connected with a first protrusion 17 , and the right bottom surface of the mounting tube 4 is fixedly connected with a rectangular plate 18 .

[0040] Reference Figure 1-Figure 10 In some embodiments, the top surface of the rectangular plate 18 is fixedly connected to a piston cylinder 19, the internal piston of the piston cylinder 19 is connected to a piston plate 20, the top surface of the piston plate 20 is fixedly connected to a push rod 21, and the top surface of the push rod 21 is fixedly connected to a slider 22.

[0041] In the present invention, the dual-axis motor 5 is started to control the soft water-absorbing scraper 8 and the hard scraper 9 to clean the parabolic antenna 2. At the same time, the dual-axis motor 5 drives the second rotating rod 16 to rotate synchronously, thereby driving the first protrusion 17 to rotate. When the protruding part of the first protrusion 17 rotates, the slider 22 can be pushed upward, and the slider 22 drives the push rod 21 to push the piston plate 20 to compress the air in the piston cylinder 19; the push rod 21 is slidably connected to the piston cylinder 19, and when the slider 22 drives the push rod 21 upward, it helps to make the push rod 21 slide up and down more stably.

[0042] A second spring 23 is sleeved on the surface of the push rod 21, one end of the second spring 23 is fixedly connected to the slider 22, and the other end of the second spring 23 is fixedly connected to the piston cylinder 19. A conveying hose 24 penetrates the surface of the feed rod 3 close to the soft water-absorbing scraper 8, and the conveying hose 24 is fixedly connected to the feed rod 3.

[0043] A spray plate 25 is fixedly connected to the bottom surface of the delivery hose 24, and one end of the delivery hose 24 away from the spray plate 25 is fixedly connected to the piston cylinder 19. A one-way valve 26 is fixedly installed on the surface of the delivery hose 24. A support plate 27 is fixedly connected to the top right surface of the bottom support frame 1, and a cleaning agent barrel 28 is placed on the top surface of the support plate 27. A suction pipe 29 is fixedly connected between the cleaning agent barrel 28 and the piston cylinder 19, and a one-way valve 26 is fixedly installed on the suction pipe 29 and the delivery hose 24.

[0044] In the present invention, the push rod 21 pushes upward and squeezes the second spring 23. When the first protrusion 17 rotates to the non-protruding part, the second spring 23 causes the push rod 21 to pull the piston plate 20 downward to reset, thereby driving the slider 22 to reset, and at the same time, the cleaning agent is sucked from the cleaning agent barrel 28 through the suction tube 29. Then the first protrusion 17 causes the slider 22 to drive the push rod 21 upward again, squeezes the cleaning agent through the piston plate 20, squeezes it out of the delivery hose 24, and enters the spray plate 25. Then the spray plate 25 sprays the parabolic antenna 2 is cleaned, and the dust that is difficult to remove is cleaned by reciprocating operation, so that the cleaning agent can be used to assist in cleaning while the soft water-absorbing scraper 8 and the hard scraper 9 are cleaning, so that the cleaning effect is better and the dust on the parabolic antenna 2 is removed faster; the one-way valve 26 can prevent the cleaning agent from being squeezed out from the suction pipe 29 when squeezing, and prevent the cleaning agent from being sucked from the delivery hose 24 when sucking; of course, the suction pipe 29 and the cleaning agent barrel 28 can be disassembled to achieve scraping of dust while assisting the jet airflow to blow it away.

[0045] Reference Figure 1-Figure 13 In some embodiments, a mounting circular plate 30 is fixedly connected to the back surface of the parabolic antenna 2, and the mounting circular plate 30 is rotatably connected to the first rotating rod 6. An L-shaped plate 31 is fixedly connected to the top surface of the mounting circular plate 30. The left side surface of the L-shaped plate 31 is fixedly connected to the parabolic antenna 2. A limiting groove is provided on the bottom surface of one end of the L-shaped plate 31 away from the mounting circular plate 30, and a limiting slide rod 32 is slidably connected in the limiting groove of the L-shaped plate 31.

[0046] In the present invention, the limiting sliding groove in the L-shaped plate 31 allows the limiting sliding rod 32 to only slide vertically in the limiting sliding groove of the L-shaped plate 31 .

[0047] The bottom surface of the limiting slide rod 32 is fixedly connected with a knocking rod 33, the bottom surface of the right end of the knocking rod 33 is hinged with an inclined plate 34, the bottom surface of the inclined plate 34 is hinged with a driving rod 35, and the surface of the first rotating rod 6 is penetrated by a second protrusion 36, and the second protrusion 36 is fixedly connected to the first rotating rod 6.

[0048] A guide rod 37 is fixedly connected to the top surface of the driving rod 35. The top of the guide rod 37 passes through the L-shaped plate 31 and is slidably connected to the L-shaped plate 31. A third spring 38 is sleeved on the surface of the guide rod 37. One end of the third spring 38 is fixedly connected to the driving rod 35, and the other end of the third spring 38 is fixedly connected to the L-shaped plate 31.

[0049] In the present invention, while the dual-axis motor 5 drives the first rotating rod 6 to rotate, it can also drive the second protrusion 36 to rotate. When the protrusion of the second protrusion 36 rotates to contact the driving rod 35, the driving rod 35 will slide upward. Under the hinged connection of the inclined plate 34 and the limited sliding action of the limiting slide 32, the limiting slide 32 drives the knocking rod 33 to slightly knock the L-shaped plate 31, so that the mounting circular plate 30 and the parabolic antenna 2 as a whole will produce a slight vibration, so that some dust and accumulated water as well as some silt and impurities adsorbed on the parabolic antenna 2 can be shaken off, which is better. The auxiliary soft water-absorbing scraper 8 and the hard scraper 9 scrape the impurities on the parabolic antenna 2 to make the dust and the like fall off faster; when the driving rod 35 moves upward, the third spring 38 will be compressed upward through the guide rod 37 to slide. When the protrusion of the second protrusion 36 does not conflict with the driving rod 35, the third spring 38 will automatically drive the guide rod 37 and the driving rod 35 to reset downward, thereby driving the inclined plate 34 and the knocking rod 33 to reset. In this reciprocating operation, the knocking rod 33 can repeatedly knock on the L-shaped plate 31, causing the parabolic antenna 2 to vibrate slightly as a whole, so that some stubborn dirt can be removed.

[0050] 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.
