Description

Technical Field

[0001] This application relates to the field of satellite signal receiving equipment, and in particular to a surface treatment device for satellite signal receiving equipment. Background Technology

[0002] Ground-based satellite signal reception typically uses parabolic satellite dishes (commonly known as satellite dishes) for reflection reception. When used outdoors for extended periods, the paint layer on the reflective surface of parabolic satellite dishes will gradually peel off and rust due to the effects of rain, air, and sunlight. Rust will affect the surface smoothness of the antenna, degrade the focusing effect, and weaken the signal received by the parabolic satellite dish. Therefore, it is necessary to maintain the surface of parabolic satellite dishes regularly.

[0003] In related technologies, a surface treatment device for satellite signal receiving equipment is proposed, including a main support plate. A switching shaft is rotatably provided on the right end face of the main support plate. A rotating motor is fixedly provided on the upper end face of the switching shaft. The upper end of the rotating motor is poweredly connected to the rotating shaft. A support mechanism is provided on the upper end of the rotating shaft. A grinding mechanism is provided on the upper side of the parabolic satellite antenna. The grinding mechanism includes a component plate. A flexible wrapping surface is fixedly connected to the lower end face of the component plate. An air-filled cavity is formed between the flexible wrapping surface and the component plate. Sandpaper is detachably installed on the lower surface of the flexible wrapping surface.

[0004] The aforementioned technologies have the following drawbacks: the degree of corrosion varies at different locations on the surface of the parabolic satellite antenna. Inflating the air chamber and then applying sandpaper to the surface of the parabolic satellite antenna, covering the entire surface with sandpaper and performing all-around polishing, has two drawbacks. First, the larger the contact area, the lower the pressure, resulting in poor polishing effect and long polishing time. Second, there is a possibility of over-polishing, which accelerates the wear and tear of the parabolic satellite antenna and wastes resources. Summary of the Invention

[0005] To address the limitation that only parabolic satellite antennas can be uniformly polished from all directions, this application provides a surface treatment device for satellite signal receiving equipment.

[0006] The surface treatment device for a satellite signal receiving equipment provided in this application adopts the following technical solution:

[0007] A surface treatment device for a satellite signal receiving equipment includes: a frame and a cleaning device and a fixing device disposed on the frame. The cleaning device includes a cleaning head disposed on the frame. The frame is provided with a first driving mechanism for driving the cleaning head to rotate along the axial direction of a parabolic satellite antenna, a second driving mechanism for driving the cleaning head to slide radially along the parabolic satellite antenna, a third driving mechanism for driving the cleaning head to rotate, and a fourth driving mechanism for driving the cleaning head to move up and down along the axial direction of the parabolic satellite antenna.

[0008] By adopting the above technical solution, under the combined action of the first drive mechanism, the second drive mechanism, the third drive mechanism and the fourth drive mechanism, the cleaning head rotates on its own axis while revolving and rising and falling along the axis of the parabolic satellite antenna, and translates radially along the parabolic satellite antenna. This allows for point-to-point or all-round grinding of the parabolic satellite antenna, improving the grinding effect and reducing the loss of the parabolic satellite antenna.

[0009] Optionally: The first drive mechanism includes a first motor mounted on a frame, a support rod on the first output shaft of the first motor, the support rod extending radially along the parabolic satellite antenna, and the cleaning head mounted on the support rod.

[0010] By adopting the above technical solution, the first motor drives the support rod to revolve along the axis of the parabolic satellite antenna, and the support rod drives the cleaning head to revolve along the axis of the parabolic satellite antenna. The structure is simple and the drive is efficient.

[0011] Optionally, the second drive mechanism includes a second lead screw rotatably connected to the support rod, the second lead screw extending along the extension direction of the support rod, the cleaning head slidably connected to the support rod along the extension direction of the support rod, the second lead screw passing through the cleaning head and threadedly connected to the cleaning head, a second driven gear coaxially provided on the second lead screw, and a second driving gear ring meshing with the second driven gear on the frame, the second driving gear ring being coaxial with the parabolic satellite antenna.

[0012] By adopting the above technical solution, when the first motor drives the cleaning head to revolve along the axial direction of the parabolic satellite antenna, the second driven gear revolves along the second driving gear ring, the second driven gear rotates on its own axis, the second driven gear drives the second lead screw to rotate, and the second lead screw drives the cleaning head to slide radially back and forth along the parabolic satellite antenna. One first motor can drive the cleaning head to revolve along the axial direction and slide radially back and forth along the parabolic satellite antenna. The transmission is efficient, energy-saving and environmentally friendly, which is in line with the concept of sustainable development.

[0013] Optionally: The third drive mechanism includes a support block slidably connected to the support rod along the extension direction of the support rod, the second lead screw passes through the support block and is threadedly connected to the support block, the support block is provided with a third motor, and the cleaning head is provided on the third output shaft of the third motor.

[0014] By adopting the above technical solution, the third motor drives the cleaning head to rotate. When polishing the parabolic satellite antenna, the cleaning head moves while rotating, which improves the polishing effect.

[0015] Optionally: The fourth drive mechanism includes a telescopic rod mounted on the third output shaft of the third motor. The telescopic rod extends and retracts along the axial direction of the parabolic satellite antenna. The cleaning head is mounted on the telescopic rod. A support plate is slidably connected to the support block along the axial direction of the parabolic satellite antenna. The cleaning head is rotatably connected to the support plate. A fourth lead screw is mounted on the support block. The fourth lead screw extends along the axial direction of the parabolic satellite antenna. The fourth lead screw passes through the support plate and is threadedly connected to the support plate. A third driving gear is mounted on the third output shaft. A third driven gear that meshes with the third driving gear is slidably connected to the fourth lead screw along the extension direction of the fourth lead screw. An adjustment component is mounted on the fourth lead screw for adjusting the position of the third driven gear so that the third driven gear meshes with or separates from the third driving gear.

[0016] By adopting the above technical solution, under the adjustment of the adjustment component, when the third driving gear and the third driven gear mesh, the third motor drives the cleaning head to rotate. At the same time, under the transmission action of the third driving gear and the third driven gear, the fourth lead screw rotates, the fourth lead screw drives the support plate to rise and fall, and the support plate drives the cleaning head to rise and fall along the axial direction of the parabolic satellite antenna. One third motor can simultaneously drive the cleaning head to rotate and rise and fall, which is highly efficient, energy-saving and environmentally friendly, and in line with the concept of sustainable development. When it is necessary to perform fixed-height grinding on the parabolic satellite antenna, under the adjustment of the adjustment component, the third driving gear and the third driven gear separate, and the third motor only drives the cleaning head to rotate.

[0017] Optionally, the adjustment assembly includes first electromagnets respectively located at both ends of the third driven gear, and second electromagnets that attract the first electromagnets are located on both sides of the third driven gear on the fourth lead screw.

[0018] By adopting the above technical solution, under the attraction of the first electromagnet and the second electromagnet, the third driven gear slides along the axial direction of the fourth lead screw, thereby realizing the meshing or separation between the third driving gear and the third driven gear. The structure is simple and the adjustment is convenient.

[0019] Optionally: The telescopic rod is provided with an air bladder at its end, and the cleaning head is located at the bottom of the air bladder.

[0020] By adopting the above technical solution, the cleaning head is flexibly attached to the parabolic satellite antenna, which reduces the possibility of damage to the parabolic satellite antenna and extends its service life.

[0021] Optional: The support rod is equipped with a blower, the blower's exhaust head is equipped with an inflation pipe, the telescopic rod is equipped with an inflation head, the inflation head is coaxially rotatably connected to an inflation ring, the airbag is located at the bottom of the inflation head, the bottom of the airbag is equipped with an exhaust hole, the exhaust hole faces the parabolic satellite antenna, the blower, inflation pipe, inflation ring, inflation head and airbag are connected in sequence, and the air intake volume in the airbag is greater than the exhaust volume.

[0022] By adopting the above technical solution, the gas generated by the blower passes sequentially through the inflation pipe, inflation ring, inflation head, and airbag before being sprayed onto the surface of the parabolic satellite antenna. While polishing the parabolic satellite antenna, it also cleans up the debris, reducing the possibility of debris adhering to the parabolic satellite antenna again. Since the inflation ring is rotatably connected to the inflation head, the possibility of the inflation pipe becoming tangled is reduced. Because the inflation volume in the airbag is greater than the deflation volume, the airbag is always saturated while cleaning debris, thus playing a role in flexible support.

[0023] Optional: The blower has an exhaust pipe at its air inlet head, an exhaust ring and a filter box on the support rod, an exhaust hole on the exhaust ring facing the parabolic satellite antenna, and the exhaust ring, filter box, exhaust pipe and blower are connected in sequence.

[0024] By adopting the above technical solution, the blown debris passes through the exhaust hole and exhaust ring in sequence and enters the filter box, reducing the possibility of debris being blown up and polluting the environment or causing secondary pollution to the parabolic satellite antenna, and improving the cleaning effect; one blower can simultaneously achieve the cleaning and collection of debris, which is energy-saving and environmentally friendly, and in line with the concept of sustainable development.

[0025] Optionally, the fixing device includes a cylinder mounted on a frame, with the piston rod of the cylinder facing the cleaning head. A bracket is provided on the piston rod of the cylinder, and multiple negative pressure heads are arranged around the bracket. The negative pressure heads are used to adhere to the back of the parabolic satellite antenna and fix the parabolic satellite antenna in place.

[0026] By adopting the above technical solution, the parabolic satellite antenna is placed on multiple negative pressure heads. Under the adsorption of the negative pressure heads, the parabolic satellite antenna is fixed. The cylinder drives the parabolic satellite antenna to rise and fall, which is convenient for cleaning and disassembly. The structure is simple and the fixation is stable.

[0027] In summary, this application has the following beneficial effects:

[0028] 1. Under the combined action of the first drive mechanism, the second drive mechanism, the third drive mechanism and the fourth drive mechanism, the cleaning head rotates on its own axis while revolving and moving up and down along the axis of the parabolic satellite antenna and translating radially along the parabolic satellite antenna. This allows for fixed-point or all-round grinding of the parabolic satellite antenna, improving the grinding effect and reducing the loss of the parabolic satellite antenna.

[0029] 2. The airbag blows up the polishing debris, and the exhaust ring collects the debris, cleaning it in real time, which effectively reduces the possibility of secondary pollution and improves the polishing effect. Attached Figure Description

Detailed Implementation

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This embodiment: A surface treatment device for a satellite signal receiving equipment, referring to... Figure 1 and Figure 2 It includes: a frame 1 and a cleaning device and a fixing device mounted on the frame 1. During grinding, the fixing device is used to fix the parabolic satellite antenna, and the cleaning device is used to grind the parabolic satellite antenna. The operation is convenient and the grinding efficiency is improved.

[0038] The fixing device includes a cylinder 81 installed at the bottom of the frame 1. The piston rod of the cylinder 81 faces upward, and a bracket 82 is fixedly connected to the piston rod of the cylinder 81. The bracket 82 is cross-shaped, and four negative pressure heads 83 are arranged around the bracket 82. The negative pressure heads 83 are located at the ends of the bracket 82 and face upward. The negative pressure heads 83 are used to adhere to the back of the parabolic satellite antenna and fix the parabolic satellite antenna.

[0039] During polishing, cylinder 81 drives bracket 82 to descend to a predetermined height, which facilitates the installation of the parabolic satellite antenna by the staff. During installation, the back of the parabolic satellite antenna is placed against bracket 82. Under the adsorption of negative pressure head 83, the parabolic satellite antenna is fixed. Cylinder 81 drives the parabolic satellite antenna to rise to a predetermined height, which facilitates the cleaning device to polish the parabolic satellite antenna.

[0040] The cleaning device includes a cleaning head 2 located on top of the frame 1. The cleaning head 2 is sandpaper and faces downwards. It should be noted that an airbag 61 is fixedly connected between the frame 1 and the cleaning head 2. The advantage of this arrangement is that the airbag 61 provides flexible support, which on the one hand makes the cleaning head 2 fit more tightly with the parabolic satellite antenna, resulting in better polishing effect; on the other hand, it reduces the possibility of damage to the parabolic satellite antenna.

[0041] The frame 1 is provided with a first drive mechanism for driving the cleaning head 2 to revolve around the axis of the parabolic satellite antenna, a second drive mechanism for driving the cleaning head 2 to slide radially along the parabolic satellite antenna, a third drive mechanism for driving the cleaning head 2 to rotate, and a fourth drive mechanism for driving the cleaning head 2 to move up and down along the axis of the parabolic satellite antenna.

[0042] After cylinder 81 raises the parabolic satellite antenna to a predetermined height, under the combined action of the first drive mechanism, the second drive mechanism, the third drive mechanism, and the fourth drive mechanism, the cleaning head 2 rotates on its own axis while revolving and rising and falling along the axis of the parabolic satellite antenna, and translates radially along the parabolic satellite antenna. This allows for fixed-point, fixed-height, or all-around grinding of the parabolic satellite antenna, improving the grinding effect and reducing the loss of the parabolic satellite antenna.

[0043] The first drive mechanism includes a first motor 21 mounted on the top of the frame 1, with the first output shaft of the first motor 21 facing downwards. A support rod 22 is fixedly connected to the first output shaft of the first motor 21, extending radially along the parabolic satellite antenna. The cleaning head 2 is mounted on the bottom of the support rod 22. During grinding, the first motor 21 drives the support rod 22 to rotate along the axial direction of the parabolic satellite antenna, and the support rod 22 drives the cleaning head 2 to rotate along the axial direction of the parabolic satellite antenna.

[0044] The second drive mechanism includes a second lead screw 31 rotatably connected to the support rod 22. The second lead screw 31 extends along the extension direction of the support rod 22 and is parallel to the support rod 22. The cleaning head 2 is slidably connected to the support rod 22 along the extension direction of the support rod 22. The support rod 22 has a groove for the cleaning head 2 to slide. The second lead screw 31 passes through the cleaning head 2 and is threadedly connected to the cleaning head 2. A second driven gear 32 is coaxially fixedly connected to the end of the second lead screw 31. A second driving gear ring 33 that meshes with the second driven gear 32 is fixedly connected to the frame 1. The second driving gear ring 33 is coaxial with the parabolic satellite antenna and is located on the periphery of the support rod 22.

[0045] When the first motor 21 drives the cleaning head 2 to revolve along the axial direction of the parabolic satellite antenna, the second driven gear 32 abuts against the second driving gear ring 33 and slides along the second driving gear ring 33. The second driving gear ring 33 drives the second driven gear 32 to rotate, and the second driven gear 32 drives the second lead screw 31 to rotate. The second lead screw 31 drives the cleaning head 2 to slide back and forth along the support rod 22. The first motor 21 alone achieves omnidirectional coverage of the parabolic satellite antenna by the cleaning head 2, which is energy-saving, environmentally friendly, and in line with the concept of sustainable development.

[0046] Reference Figure 3 and Figure 4 The third drive mechanism includes a support block 41 slidably connected within a groove, and a second lead screw 31 passing through and threadedly connected to the support block 41. A third motor 42 is mounted at the bottom of the support block 41, with its third output shaft facing downwards. The cleaning head 2 is mounted on the third output shaft of the third motor 42. As the cleaning head 2 moves along the parabolic satellite antenna, the third motor 42 drives the cleaning head 2 to rotate, resulting in relative rotation between the cleaning head 2 and the parabolic satellite antenna, further improving the polishing effect.

[0047] The fourth drive mechanism includes a telescopic rod 51 fixedly connected to the third output shaft of the third motor 42. The telescopic rod 51 extends and retracts along the axial direction of the parabolic satellite antenna. The telescopic rod 51 includes a first rod body and a second rod body. The first rod body is fixedly connected to the end of the third output shaft, and the second rod body is slidably connected to the first rod body along the length direction of the first rod body 91.

[0048] The cleaning head 2 is installed at the end of the second rod. A support plate 52 is slidably connected to the support block 41 along the axial direction of the parabolic satellite antenna. The support plate 52 is located below the third motor 42. The cleaning head 2 is rotatably connected to one side of the support plate 52. A fourth lead screw 53 is rotatably connected to the support block 41. The fourth lead screw 53 extends along the axial direction of the parabolic satellite antenna. The fourth lead screw 53 passes through the support plate 52 and is threadedly connected to the support plate 52.

[0049] A third drive gear 54 is coaxially fixedly connected to the third output shaft. A third driven gear 55 that meshes with the third drive gear 54 is slidably connected to the fourth lead screw 53 along the extension direction of the fourth lead screw 53. An adjustment component is provided on the fourth lead screw 53 for adjusting the position of the third driven gear 55 so that the third driven gear 55 meshes with or separates from the third drive gear 54.

[0050] When the parabolic satellite antenna needs to be polished in all directions, under the adjustment of the adjustment component, the third driving gear 54 and the third driven gear 55 mesh, and the third motor 42 drives the cleaning head 2 to rotate along the support plate 52. At the same time, under the transmission action of the third driving gear 54 and the third driven gear 55, the fourth lead screw 53 rotates. The fourth lead screw 53 drives the support plate 52 to rise and fall, and the support plate 52 drives the cleaning head 2 to rise and fall along the axis of the parabolic satellite antenna, thereby realizing the all-round polishing of the parabolic satellite antenna.

[0051] When the parabolic satellite antenna needs to be ground at a fixed height, the third driven gear 55 and the third driving gear 54 are separated under the adjustment of the adjustment component, and the third motor 42 only drives the cleaning head 2 to rotate along the support plate 52, thereby realizing the grinding of the parabolic satellite antenna at a fixed height.

[0052] The adjustment assembly includes a first electromagnet 56 fixedly connected to the top and bottom of the third driven gear 55, and a second electromagnet 57 fixedly connected to the fourth lead screw 53 above and below the third driven gear 55, which is attracted to the first electromagnet 56. It should be noted that both the first electromagnet 56 and the second electromagnet 57 have their own power supply.

[0053] When the first electromagnet 56 and the second electromagnet 57 are energized, and the first electromagnet 56 at the top of the third driven gear 55 attracts the second electromagnet 57 above the third driven gear 55, the third driven gear 55 slides to the top of the fourth lead screw 53, and engages with the third driving gear 54. When the first electromagnet 56 at the bottom of the third driven gear 55 attracts the second electromagnet 57 below the third driven gear 55, the third driven gear 55 slides to the bottom of the fourth lead screw 53, and disengages from the third driving gear 54.

[0054] When grinding a parabolic satellite antenna, a large amount of debris is stirred up, causing secondary pollution. Therefore, in this embodiment, a blower 62 is installed on one side of the support rod 22. An inflation pipe 63 is fixedly connected to the exhaust head of the blower 62. The inflation pipe 63 is a flexible hose. A hollow inflation head 64 is fixedly connected to the bottom of the second rod 92. The outer ring of the inflation head 64 is provided with an array of first through holes. A hollow inflation ring 65 is coaxially rotatably connected to the inflation head 64. The inner ring of the inflation ring 65 is provided with an array of second through holes.

[0055] The airbag 61 is fixedly connected to the bottom of the inflation head 64. The bottom periphery of the airbag 61 is provided with an array of exhaust holes 66, which face the parabolic satellite antenna. The blower 62, inflation pipe 63, inflation ring 65, inflation head 64 and airbag 61 are connected in sequence. The air intake volume in the airbag 61 is greater than the air exhaust volume.

[0056] The gas generated by the blower 62 passes sequentially through the inflation pipe 63, inflation ring 65, inflation head 64, air bladder 61, and exhaust port 66 before being blown onto the parabolic satellite antenna, cleaning debris in real time, reducing the possibility of secondary pollution and improving the polishing effect. In addition, because the air intake volume in the air bladder 61 is greater than the exhaust volume, the air bladder 61 can be kept saturated in real time, providing flexible support for the cleaning head 2.

[0057] Debris raised in the air is easily dispersed, causing secondary pollution. Therefore, in this embodiment, an exhaust pipe 71 is fixedly connected to the air inlet of the blower 62, and an exhaust ring 72 and a filter box 73 are fixedly connected to the support rod 22. The exhaust ring 72 is located around the parabolic satellite antenna, and an array of exhaust holes 74 are arranged around the bottom of the exhaust ring 72, facing the parabolic satellite antenna. The exhaust ring 72, filter box 73, exhaust pipe 71, and blower 62 are connected in sequence. The raised debris passes through the exhaust holes 74 and the exhaust ring 72 in sequence and enters the filter box 73, where the debris is collected in real time, effectively reducing the possibility of secondary pollution.

[0058] The implementation principle of the surface treatment device for a satellite signal receiving equipment according to this application embodiment is as follows: a negative pressure head 83 abuts against the back of a parabolic satellite antenna to fix the parabolic satellite antenna, and a cylinder 81 raises the parabolic satellite antenna to a predetermined height. A first motor 21 drives a cleaning head 2 to rotate along the axial direction of the parabolic satellite antenna. Under the transmission action of a second driving gear ring 33 and a second driven gear 32, a second lead screw 31 rotates, and the cleaning head 2 slides radially back and forth along the parabolic satellite antenna.

[0059] The third motor 42 drives the cleaning head 2 to rotate. Under the transmission action of the third driving gear 54 and the third driven gear 55, the cleaning head 2 moves up and down along the axial direction of the parabolic satellite antenna, thereby achieving all-round grinding of the parabolic satellite antenna. Under the adjustment action of the first electromagnet 56 and the second electromagnet 57, when the third driving gear 54 and the third driven gear 55 are separated, the cleaning head 2 does not move up and down along the axial direction of the parabolic satellite antenna, thereby achieving fixed-height grinding of the parabolic satellite antenna. This improves the grinding effect and reduces the loss of the parabolic satellite antenna.

[0060] The gas generated by the blower 62 passes sequentially through the inflation pipe 63, inflation ring 65, inflation head 64, air bag 61, and exhaust port 66 before being blown onto the parabolic satellite antenna, cleaning up debris in real time. The airborne debris passes sequentially through the exhaust port 74 and exhaust ring 72 before entering the filter box 73, where it is collected in real time, effectively reducing the possibility of secondary pollution.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
