Description

Technical Field

[0001] The present application relates to the technical field of portable satellite antennas, and in particular to a maintenance device for a portable satellite station. Background Art

[0002] A portable satellite station is a mobile communication station, which usually consists of a satellite antenna, power amplifier, power system and base. When in use, it can be quickly deployed on any terrain, and a satellite communication link can be established within 3 minutes to achieve two-way transmission of images, data and voice. In natural disasters or emergencies, conventional communication facilities may not work properly. Portable satellite base stations can provide temporary communication networks to help rescuers communicate and coordinate. In remote areas or outdoor adventures, conventional communication facilities may not be covered. Portable satellite base stations can provide reliable communication services to ensure the safety of participants. In remote areas or places without ground communication facilities, portable satellite base stations can provide reliable communication services to meet the communication needs of local residents.

[0003] Portable satellite stations are usually used in areas that are not covered by the network, such as plateaus, forests or deserts. This means that the portable satellite station will often be exposed to the environment as a whole. Therefore, it is easy for the portable satellite station to be covered with dust and other impurities. Among them, satellite antennas and power amplifiers are the most affected. Impurities such as dust or dead leaves on the satellite antenna will affect the effect of its signal transmission; the power amplifier will generate heat when working, so heat dissipation fins will be set at the end to improve its heat dissipation capacity, but the gaps between these heat dissipation fins are also easy to accumulate dust, dead leaves and other impurities. If these impurities are not cleaned in time, it will affect the heat dissipation function of the power amplifier, and then affect the operation of the power amplifier.

[0004] At present, the traditional cleaning and maintenance method for portable satellite stations is to use a rag to process the surface of the satellite antenna and the cooling fins of the power amplifier device. When cleaning with a rag, dust is easy to adhere to the rag, which requires users to frequently clean or replace the rag. In addition, the rag does not thoroughly clean the dust and other impurities in some joints on the surface of the satellite antenna and the gaps between the cooling fins of the power amplifier device. These dusts will still have a negative impact on the operation of the portable satellite station. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0027] like Figure 1-Figure 3 As shown, a maintenance device for a satellite portable station disclosed in the present application includes an equipment box 2 detachably mounted on a satellite portable station base 1, a vacuum main unit 3 is arranged in the equipment box 2, one side of the vacuum main unit 3 is connected to a cleaning head 5 via a rubber hose 4; the interior of the cleaning head 5 is a cavity structure, and one side thereof is open; a cleaning brush 6 is arranged at the open portion of the cleaning head 5, and the end shafts at both ends of the cleaning brush 6 are rotatably connected to the cleaning head 5; one of the end shafts of the cleaning brush 6 is connected to a power unit 8 via a power transmission component 7; the power unit 8 can drive the cleaning brush 6 to rotate at the open portion of the cleaning head 5 via the power transmission component 7, and clean the satellite portable station antenna 9 or the heat dissipation fins 10 of the satellite portable station power amplifier device through the bristles of the cleaning brush 6.

[0028] In the above embodiments, the satellite portable station is generally composed of an antenna, a power amplifier, a base, and a power system. The power amplifier has a gain effect on the satellite antenna receiving and transmitting data. When the power amplifier is overheated during operation, it will affect other use effects. Therefore, the power amplifier is usually provided with heat dissipation fins for improving the heat dissipation capacity. In addition, the antenna of the satellite portable station usually has a gap that needs to be spliced ​​in order to facilitate disassembly and assembly. When the satellite portable station is used outdoors, it is easy for dust or impurities such as dead branches and leaves to adhere to its surface. These impurities will affect the use of the antenna and the power amplifier. Therefore, users usually use a rag to clean the heat dissipation fins of the antenna and the power amplifier when inspecting and maintaining the satellite portable station.

[0029] When using a rag to clean small particles of impurities such as dust, these small particles of impurities often adhere to the rag. In order to ensure the cleaning effect of the rag during the cleaning process, the user needs to frequently clean the rag or replace it with a new one to ensure the cleaning effect. In addition, during the cleaning process, it is difficult to effectively clean some joint gaps on the antenna or the grooves between the heat dissipation fins of the power amplifier equipment, which affects the final maintenance and cleaning effect. Even these dusts that cannot be cleaned will still have a certain negative impact on the work of the satellite portable station in the future.

[0030] The equipment box 2 of the present application has the function of storing the entire maintenance device, and the equipment box 2 is connected to the base of the satellite portable station, so that the maintenance device can be used at any time when the satellite portable station needs to be cleaned. The vacuum main unit 3 of the present application is provided with a high-speed exhaust fan. When the high-speed exhaust fan is working, negative pressure can be generated in the vacuum main unit 3, so that the cleaning head 5 can generate suction through the rubber hose 4. Its working principle and method of use are similar to those of industrial vacuum cleaners in the prior art, so its specific structure is not repeated here. The cleaning head 5 connected to the vacuum main unit 3 through the rubber hose 4 can generate suction at its open part when the vacuum main unit 3 is working, so that the user holds the handle under the cleaning head 5 to move it along the antenna of the satellite portable station or the heat dissipation fin of the power amplifier device, and the cleaning head 5 can use the suction at its open part to suck away impurities such as dust that are not firmly attached to the heat dissipation fins of the antenna and the power amplifier device.

[0031] The present application also provides a cleaning brush 6 in the open end of the cleaning head 5. When the power unit 8 rotates the cleaning head 5 with the power transmission assembly 7, the cleaning brush 6 contacts the antenna of the satellite portable station or the heat sink of the power amplifier device, and some dust impurities on their surface that are difficult to absorb can be peeled off. The peeled dust and other impurities will be sucked away through the open end of the cleaning head 5. In addition, the surrounding side of the cleaning brush 6 has uniform and dense bristles. When used, these bristles can not only effectively clean the joints of the antenna in the satellite portable station, but also penetrate into the gaps between the heat sinks when cleaning the heat sinks of the power amplifier device. Compared with the prior art, the trouble of frequent cleaning of the rag is saved, the operation is not only simpler and more convenient, but also the cleaning is more comprehensive and clean. For the cleaned satellite portable station, it can ensure that it can subsequently transmit data to the user continuously and stably.

[0032] Furthermore, if Figure 2 As shown, a receiving cavity 11 is provided on a side wall adjacent to a section of the cleaning head 5 and the cleaning brush 6 , and the power transmission assembly 7 is installed in the receiving cavity 11 .

[0033] In the above embodiments, the present application sets the power transmission component 7 in one of the side walls of the cleaning head 5. Compared with setting the power transmission component 7 inside the cleaning head 5, it can avoid the cleaning head 5 from inhaling dust and other impurities and affecting the power transmission component 7, and can also make the internal structure of the cleaning head 5 more concise.

[0034] Furthermore, if Figure 2 and Figure 3 As shown, the power transmission assembly 7 includes a first pulley 71 and a second pulley 72 arranged in the accommodating chamber 11, and the first pulley 71 and the second pulley 72 are connected by a transmission belt 73; the end shaft of the cleaning brush 6 close to the accommodating chamber 11 passes through the side wall of the adjacent side of the accommodating chamber 11 and is fixedly connected to the first pulley 71, and the second pulley 72 is connected to the power unit 8.

[0035] In the above embodiments, the power unit 8 can transmit power to the first pulley 71 through the second pulley 72 and the transmission belt 73, and then the cleaning brush 6 is driven by the first pulley 71 to complete the rotational cleaning effect inside the cleaning head 5.

[0036] Furthermore, if Figure 2 and Figure 3 As shown, the power unit 8 includes a power fan 81 arranged in the cleaning head 5, the power fan 81 is arranged parallel to one side of the cleaning brush 6, and the distance between the power fan 81 in the cleaning head 5 and its opening is greater than the distance between the cleaning brush 6 and its opening; a center shaft 82 passes through the center of the power fan 81 and the two are fixedly connected, both ends of the center shaft 82 are rotatably connected to the cleaning head 5, and the end of the center shaft 82 close to the accommodating chamber 11 is fixedly connected to the second pulley 72.

[0037] In the above embodiments, the fan blade cross section of the power fan 81 of the present application is V-shaped. When the vacuum main unit 3 is working, the cleaning head 5 will generate suction at the open position. In addition to sucking impurities such as dust into the dust collecting components in the vacuum main unit 3, the suction can also allow air with a certain flow rate to pass through the power fan 81. When these air flows through the power fan 81, they will contact the V-shaped fan blades of the power fan 81. The V-shaped fan blades will be pushed by the airflow, so that the power fan 81 can rotate with the center shaft 82 inside the cleaning head 5 at high speed. One end of the rotating center shaft 82 is connected to the second pulley 72, so the second pulley 72 will be rotated together with the power fan 81, and the power will be transmitted to the first pulley 71 and the cleaning brush 6 through the transmission belt 73, so that the effect of driving the cleaning brush 6 to rotate can be achieved by the suction at the cleaning head 5. In this way, not only can the utilization rate of the suction at the cleaning head 5 be improved, but also the efficient rotation of the cleaning brush 6 can be ensured to achieve the maintenance and cleaning effect of the satellite portable station. The power fan 81 of the present application is arranged at a position deeper than the cleaning brush 6 in the cleaning head 5, so as to prevent the power fan 81 from touching the antenna surface of the satellite portable station or the surface of the heat sink of the power amplifier device when rotating, causing scratches on their surfaces, and also to prevent the power fan 81 from affecting the cleaning effect of the cleaning brush 6 due to obstructed rotation.

[0038] Furthermore, if Figure 3 As shown, a partition plate 12 is fixedly provided in the cleaning head 5, and the partition plate 12 can separate the power fan 81 and the cleaning brush 6 in the cleaning head 5; and there is a gap between the end of the partition plate 12 close to the opening of the cleaning head 5 and the opening of the cleaning head 5.

[0039] In the above embodiment, the partition plate 12 provided in the cleaning head 5 of the present application can separate the internal space of the cleaning head 5 into two parts, and the cleaning brush 6 and the power fan 81 are respectively located in these two parts of the space, and the power fan 81 has an independent air duct inside the cleaning head 5 through the partition plate 12, and the air duct is connected to the rubber hose 4, so that the airflow attracted by the suction generated by the rubber hose 4 will only pass through the space where the power fan 81 is located, and will not enter the space where the cleaning brush 6 is located in the cleaning head. If the power fan 81 and the cleaning brush 6 do not separate the inner cavity of the cleaning head 5 shared by the two, when the airflow flows from the open end of the cleaning head 5 to the rubber hose, it will be dispersed in all areas in the cleaning head 5. Compared with this situation, after the partition plate 12 is provided inside the cleaning head 5 of the present application, it is equivalent to reducing the aperture of the airflow channel when passing through the power fan 81. Under the premise of the same suction, the diameter of the airflow channel is appropriately reduced, which can effectively increase the flow rate of the air at the power fan 81, thereby increasing the power of the power fan 81, and the cleaning effect of the corresponding cleaning brush 6 will also be improved. When the cleaning brush 6 rotates, it will use centrifugal force to throw the dust along the tangential direction of its bristles to the space where the power fan 81 is located. In this application, the end of the partition plate 12 close to the opening is set at a certain distance from the opening of the cleaning head 5 to ensure that these dust impurities can smoothly reach the side of the partition plate 12 close to the power fan 81 so that the dust can be collected through the rubber hose 4.

[0040] Furthermore, if Figure 2 As shown, a circle of flexible rubber retaining ring 13 is fixedly provided on the outer side of the open end of the cleaning head 5.

[0041] In the above embodiments, the flexible rubber retaining ring 13 arranged on the outside of the open end of the cleaning head 5 can reduce the gap between the open end of the cleaning head and the surface of the object to be cleaned during the cleaning process, thereby increasing the suction force on the surface of the object to be cleaned and improving the cleaning effect.

[0042] Furthermore, if Figure 4 As shown, a sponge pad 14 is arranged in the equipment box 2 , and a pipe groove 15 adapted to the length of the rubber hose 4 and a head groove 16 adapted to the outer contour of the cleaning head 5 are arranged on the sponge pad 14 .

[0043] In the above embodiment, the sponge pad 14 in the equipment box 2 is arranged in the above manner. After the cleaning work of the satellite portable station is completed, the head groove 16 can be used to store the cleaning head 5, and the pipe groove 15 can be used to place the rubber hose 4. In this way, the sponge pad 14 can provide better storage and protection for the cleaning head 5 and the rubber hose 4.

[0044] Furthermore, if Figure 5As shown, the equipment box 2 is located between two brackets of the satellite portable station power amplifier device, and the height of the equipment box 2 is not greater than the height of the satellite portable station antenna 9 when it is in the folded state.

[0045] In the above embodiments, the device box 2 of the present application is arranged on the satellite portable station base 1 in the above manner, so that the whole will not be affected by the device box 2 when folding.

[0046] The implementation principle of this embodiment is as follows: when the user needs to maintain and clean the satellite portable station antenna 9 and the satellite portable station power amplifier device heat sink 10 outdoors, open the top cover of the satellite portable station equipment box 2, take out the cleaning head 5 and the rubber hose 4 from the sponge pad 14 of the equipment box 2, and then start the vacuum cleaner 3. The user first slowly moves the cleaning head 5 along the surface of the satellite portable station antenna 9. During the movement, the suction force generated by the open end of the cleaning head 5 can not only directly suck away the loose dust and other impurities on the antenna surface, but also suck away the stubborn dust impurities brushed up by the cleaning brush 6 driven by the internal power fan 81. When the user finishes cleaning the cleaning head 5 along the surface of the satellite portable station antenna 9, the maintenance and cleaning work of the satellite portable station antenna 9 is completed. Then the user can continue to move the cleaning head 5 to clean the satellite portable station power amplifier device heat sink 10, and the principle is the same as above.

[0047] The cleaning brush of the present application can not only clean some dust firmly adhered to the surface of the portable satellite station antenna 9 and the portable satellite station power amplifier device heat sink 10 during the cleaning process, but also thoroughly clean the joints on the surface of the portable satellite station antenna 9 and the gaps between the portable satellite station power amplifier device heat sink 10, and the various impurities cleaned or peeled off can be sucked into the cleaning head 5. Compared with the prior art, the present application is not only simpler and more convenient to operate, but also cleans more comprehensively and cleanly, ensuring that the cleaned portable satellite station can subsequently transmit data continuously and stably.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
