Description

Technical Field

[0001] The present invention relates to the technical field of satellite transmission microwave antenna cleaning devices, and more specifically, to a broadcasting and television satellite transmission microwave antenna cleaning device. Background Art

[0002] Satellite TV transmission technology is a technology that collects digital TV program information and sends it to a synchronous satellite 38,000 kilometers above the ground via microwaves from a satellite ground transmitting station. The synchronous satellite forwards the information back to the ground using microwaves, and the user's TV receives satellite digital TV programs through a small satellite receiving antenna with no obstruction to the satellite and a satellite set-top box. However, microwave antennas used for satellite transmission will have their service life and signal transmission affected by dust, rain, snow, ice and other factors, so they need to be cleaned.

[0003] The document with the prior art publication number CN215744959U provides a radio and television microwave antenna cleaning device, which is provided with a collection box and a steering rod, the steering rod is arranged at both ends of the collection box, and a baffle is arranged between the two steering rods. A collection plate is arranged on the baffle, and a fixing rod is arranged on the left end of the collection box. Two cutouts are arranged at the top of the fixing rod, a thread is arranged at the top of the fixing rod, a fixing ring is arranged at the top of the fixing rod, and a pressing pump is arranged on the collection box. The above-mentioned radio and television microwave antenna cleaning device has the following problems: the device is too simple in setting, and only collects water through a collection box. After entering the sponge, the antenna table surface needs to be wiped manually. The antenna table is at a high place, which is not only dangerous, but also can only clean the lower part, and cannot perform comprehensive and regular thorough cleaning of the antenna table surface. In addition, although other existing microwave antenna cleaning devices are equipped with a composite multiple drive device to adapt to the cleaning of bowl-shaped microwave antennas, this design can only achieve multi-position cleaning in different radial directions and at different angles. However, since the rotating motor drive mechanism does not have a locking function after power is cut off, the motor shaft is in a free rotation state, which makes it easy to slip under the rotation of centrifugal force and the radial staying position of the bristles can only be controlled after power is turned on.

[0004] In view of this, we propose a cleaning device for microwave antennas of broadcasting and television satellite transmissions. Summary of the invention

[0037] See also Figure 1-5 , the present invention provides a technical solution:

[0038] A radio and television satellite transmission microwave antenna cleaning device comprises a feed reflector frame 1, the feed reflector frame 1 is arranged at one end of a vertical pole 2, and a feed pole 3 is fixedly arranged in the middle of the feed reflector frame 1;

[0039] A circumferential cleaning mechanism 4 is arranged outside the feed rod 3, and the circumferential cleaning mechanism 4 comprises a transposition cleaning column 5, and a sleeve 6 which is rotatably matched with the feed rod 3 is fixedly arranged at one end of the transposition cleaning column 5;

[0040] The circumferential cleaning mechanism 4 also includes a rotation drive, which can drive the transposition cleaning column 5 to revolve;

[0041] A moving frame 7 is slidably arranged outside the transposition cleaning column 5 , at least one cleaning component is arranged outside the moving frame 7 , and a moving drive capable of driving the cleaning component on the moving frame 7 to move is also arranged inside the moving frame 7 .

[0042] A slide groove is provided on the body of the arc-shaped transposition cleaning column 5, and a plurality of arc-shaped grooves are provided in the slide groove. A mass ball is arranged in the slide groove, and is fixedly connected to one end of a spring in the slide groove body, and the other end of the spring is connected to the mass ball. A first magnetic block is embedded in the mass ball, and a second magnetic block is embedded in the moving gear 19. The first motor 13 rotates at a variable speed or a uniform speed, wherein the second motor 21 is turned on in the uniform speed rotation mode, and the second motor 21 is turned off when running at a variable speed. This design makes it possible to use the changing centripetal force to make it unnecessary to turn on the second motor 21 when performing full-position coverage cleaning. The bowl-shaped inner surface of the microwave antenna can be cleaned in all directions only by the rotation of the first motor 13. Specifically, the second motor 21 is turned off, so that the moving gear 19 is restored to a free moving state, so that the arc-shaped transposition cleaning column 5 is driven to rotate during the rotation of the first motor 13. The centrifugal force drives the mass ball to move outward. The mass ball drives the two moving gears 19 to move toward the outer side of the arc-shaped transposition cleaning column 5 under the action of the magnetic adsorption force. Since the first motor 13 rotates at a changing speed or a uniform speed and a spring is provided at the end of the mass ball, the mass ball can stay in different arc grooves at different speeds and different rotation angles, so that the inner surface of the microwave antenna can be cleaned in all directions. If cleaning at a fixed circular ring position is required, it is only necessary to operate the first motor 13 at a substantially constant speed. Considering the gravity of the mass ball itself when rotating to the lower semicircle, the speed can be larger when it is located at the top within a circular cycle, and smaller when it is located at the lower semicircle.

[0043] In this technical solution, through the setting of the circular cleaning mechanism 4, when in use, circular motion can be directly performed on the feed reflector frame 1 for cleaning, and there is no need for staff to climb to a high place for wiping and cleaning. This not only reduces the risk factor, but also, compared with manual work, the entire surface can be thoroughly cleaned by replacing the cleaning column, and there will be no missed cleaning or incomplete cleaning, thereby improving the cleaning effect and automation.

[0044] Specifically, the transposition cleaning column 5 is arranged in an arc-shaped structure, which is adapted to the curvature of the feed reflection frame 1 .

[0045] In this technical solution, the cleaning component can move along the curvature of the feed reflector frame 1 when moving, so that the bristles 16 move along the feed reflector frame 1 for cleaning, thereby further improving the cleaning effect.

[0046] Furthermore, the rotation drive includes a transmission gear 8 fixedly arranged on the outer wall of the feed rod 3, a gear cavity 10 is opened at one end of the replacement cleaning column 5, a driving gear 11 is arranged inside the gear cavity 10, and the outer wall of the driving gear 11 extends through the inner wall of the gear cavity 10 to the inside of the sleeve 6 and is meshed and connected with the transmission gear 8.

[0047] In this technical solution, the rotation drive drives the transposed cleaning column 5 to perform circular motion, thereby performing circular cleaning on the feed source reflection frame 1.

[0048] Furthermore, a limiting ring groove 9 is provided on the inner circumferential wall of the sleeve 6 , and the limiting ring groove 9 is slidably connected to the outer wall of the transmission gear 8 .

[0049] In this technical solution, the sleeve 6 restricts the transmission gear 8, thereby ensuring that the transposed cleaning column 5 performs stable circular motion and does not deviate from the surface of the feed reflector frame 1.

[0050] Furthermore, a chassis 12 is fixedly provided on the outer wall of the sleeve 6 , a first motor 13 is provided inside the chassis 12 , an output end of the first motor 13 extends through the inner wall of the chassis 12 to the inside of the gear cavity 10 and is coaxially fixedly connected with the driving gear 11 .

[0051] In this technical solution, the first motor 13 drives the driving gear 11 to rotate, and through meshing with the transmission gear 8, the circular motion of the transposition cleaning column 5 is achieved.

[0052] It is worth noting that the middle part of the movable frame 7 is in a circular structure and is arranged in a certain arc, which is compatible with the transposition cleaning column 5 .

[0053] In this technical solution, the movable frame 7 can move inward and outward on the outer wall of the transposition cleaning column 5 to be cleaned by the cleaning disk 15 .

[0054] It is worth noting that the cleaning assembly includes a fixed block 14, a cleaning disc 15 is slidably arranged inside the fixed block 14, and bristles 16 are arranged on the outside of the cleaning disc 15;

[0055] A plurality of telescopic rods 17 are disposed on the outer wall of the cleaning plate 15 , one end of the telescopic rod 17 is connected and fixed to the outer wall of the cleaning plate 15 , and the other end of the telescopic rod 17 is connected and fixed to the inner wall of the fixing block 14 .

[0056] In addition, a spring 18 is sleeved on the outer side of the telescopic rod 17 .

[0057] In this technical solution, through the setting of the cleaning component, the spring 18 pushes the cleaning plate 15 to fit tightly against the outer wall of the feed reflector frame 1, so that it can always adapt to the curvature change of the feed reflector frame 1 and always apply a certain external force to it, thereby better cleaning the surface of the feed reflector frame.

[0058] In addition, the mobile drive includes two mobile gears 19 rotatably arranged on the inner side of the mobile frame 7, an output box 20 is fixedly arranged on the outer side of the mobile frame 7, a second motor 21 is arranged inside the output box 20, and an output shaft of the second motor 21 passes through the outer wall of the output box 20 and extends to the inside of the mobile frame 7 and is coaxially fixedly connected with one of the mobile gears 19;

[0059] The mobile drive also includes a fixed rack 22 disposed on the outer wall of the transposition cleaning column 5, and the fixed rack 22 is meshedly connected with the mobile gear 19;

[0060] The shaft of the moving gear 19 is coaxially connected and fixed to the fixing block 14 .

[0061] In addition, the teeth of the movable gear 19 are arranged in an arc shape, and the fixed rack 22 is arranged in an arc shape along the outer wall of the transposition cleaning column 5 .

[0062] In this technical solution, through the setting of mobile drive, the cleaning component can move inward and outward along the transposition cleaning column while performing circular motion cleaning. While moving and cleaning, the cleaning disc is also rotating, thereby improving the cleaning effect within the same area.

[0063] When the radio and television satellite transmission microwave antenna cleaning device is needed, the controller drives the output shaft of the first motor 13 to rotate, thereby driving the driving gear 11 to rotate, and through the meshing of the driving gear 11 and the transmission gear 8, the transposition cleaning column 5 is driven to revolve around the feed rod 3, so that the bristles 16 perform cleaning work;

[0064] At the same time, the output shaft of the second motor 21 is driven to rotate, which drives the moving gear 19 to rotate, and a fixed rack 22 is set on the outer wall of the transposition cleaning column 5. Through the engagement of the transposition cleaning column 5 with the fixed rack 22, the moving frame 7 can move inward and outward on the transposition cleaning column 5. At the same time, through the setting of the moving gear 19, the fixed block 14 is driven to rotate, so that the cleaning disc 15 rotates for cleaning, thereby improving the cleaning effect. The fixed block 14 and the cleaning disc 15 are connected by a telescopic rod 17. Through the push of the spring 18, the bristles 16 are always in contact with the surface of the feed reflection frame 1, thereby ensuring the cleaning effect.

[0065] Specifically, by means of the changing centripetal force, it is not necessary to turn on the second motor 21 when performing full-position coverage cleaning. The bowl-shaped inner surface of the microwave antenna can be cleaned in all directions only by the rotation of the first motor 13. Specifically, the second motor 21 is turned off, so that the moving gear 19 is restored to a free moving state, so that the arc-shaped transposition cleaning column 5 is driven to rotate during the rotation of the first motor 13. The centrifugal force drives the mass ball to move toward the outside. The mass ball drives the two moving gears 19 toward the outside of the column of the arc-shaped transposition cleaning column 5 under the action of the magnetic adsorption force. Since the first motor 13 rotates at a changing speed or a uniform speed and a spring is provided at the end of the mass ball, the mass ball can stay in different arc grooves at different speeds and different rotation angles, so that the inner surface of the microwave antenna can be cleaned in all directions. If cleaning at a fixed circular position is required, it is only necessary to operate the first motor 13 at a substantially constant speed. Considering the gravity of the mass ball itself when rotating to the lower semicircle, the speed can be larger when it is located at the top within a circular cycle, and smaller when it is located at the lower semicircle.
