Description

Technical Field

[0001] This invention belongs to the field of outdoor protection technology for wireless communication equipment, and particularly relates to a protective mechanism for wireless communication relay equipment adapted to extreme outdoor environments. Background Technology

[0002] Outdoor wireless communication relay equipment is a key node in ensuring wireless communication network signal coverage. In order to obtain good signal propagation effect, such equipment is usually installed in unobstructed outdoor high places, such as signal towers and rooftops. However, these high places are not conducive to staff climbing up and down frequently.

[0003] In extreme salt fog environments such as coastal areas, the air circulation at high altitudes is strong, and the salt fog continues to adhere to the antenna surface with the wind. Due to the high humidity and significant temperature difference between day and night at high altitudes, it is difficult to evaporate naturally and gradually condenses and dries into a dense salt frost crystal layer.

[0004] Traditional wireless communication repeater equipment uses protective mechanisms to passively block salt spray corrosion. However, since the antennas of outdoor wireless communication repeater equipment need to transmit signals outwards, they cannot be completely blocked by the protective mechanisms. Some parts are always exposed to the outside world, so the antennas are still subject to long-term salt spray corrosion, leading to signal attenuation. At the same time, salt spray can seep into the equipment through the connection gap between the antenna and the repeater, corroding electronic components and causing malfunctions, rendering the outdoor wireless communication repeater equipment ineffective. Summary of the Invention

[0005] The purpose of this invention is to provide a protective mechanism for wireless communication relay equipment adapted to extreme outdoor environments, in order to solve the technical problems of antenna corrosion and connection sealing failure in the prior art under outdoor salt spray environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A protective mechanism for wireless communication relay equipment adapted to extreme outdoor environments includes an antenna mounted on a wireless communication repeater, and further includes: a scraping assembly including a scraping air ring for cleaning the outer surface of the antenna; a protective assembly including a folding cover for driving the scraping air ring to move up and down; and an air supply assembly including an air supply cylinder, which controls the expansion degree of the scraping air ring during the up and down movement of the scraping air ring, so that the scraping air ring is adapted to the size of the antenna.

[0007] According to some embodiments, a sealing detection component is also included, comprising: a first connecting half-cover, disposed at the connection between the wireless communication repeater and the antenna, and connected to a second connecting half-cover by bolts; a plurality of sealing rings, respectively disposed inside the first connecting half-cover and the second connecting half-cover; and an air inlet pipe, fixedly installed on the second connecting half-cover.

[0008] According to some embodiments, a unidirectional conveying assembly is also included, comprising: a fourth connecting pipe, fixedly mounted on the first connecting half-cover, with a sealing cover fixedly mounted inside; a fixing frame, fixedly mounted inside the fourth connecting pipe, with a first screw rotatably mounted thereon; a threaded frame, threadedly connected to the first screw and slidably connected to the fixing frame; a sealing block, used to seal the sealing cover and connected to the threaded frame via a first spring; a first rotating shaft, rotatably mounted on the fourth connecting pipe, with a first bevel gear fixedly mounted thereon; and a second bevel gear, fixedly mounted on the first screw and meshing with the first bevel gear.

[0009] According to some embodiments, the unidirectional conveying assembly further includes: a fifth connecting pipe, which is slidably mounted on the fourth connecting pipe, with a third connecting pipe disposed above it; and a connecting frame, one end of which is fixedly connected to the sealing block and the other end of which is fixedly connected to the fifth connecting pipe.

[0010] According to some embodiments, the protective component includes: a second connecting ring, fixedly installed on the top of the folding cover; the folding cover is threadedly connected to the first connecting half cover and the second connecting half cover, the folding cover is fixedly connected to the third connecting pipe, and the first connecting ring is fixedly installed inside the folding cover.

[0011] According to some embodiments, the gas supply assembly further includes: a winding frame, fixedly installed on the second connecting ring, on which a second rotating shaft is rotatably mounted; and a pull rope, wound around the second rotating shaft, with one end fixedly connected to the first connecting ring.

[0012] According to some embodiments, the gas supply assembly further includes: a power storage box, which is fixedly installed on the winding frame and rotatably connected to the second rotating shaft; and a coil spring, which is disposed inside the power storage box, with one end fixedly connected to the second rotating shaft and the other end fixedly connected to the power storage box.

[0013] According to some embodiments, the air supply assembly further includes: a positioning frame, fixedly installed on the accumulator box, on which an air supply cylinder is fixedly installed; a second screw, rotatably installed on the air supply cylinder and fixedly connected to the second rotating shaft; and a pressing plate, threadedly connected to the second screw and slidably connected to the air supply cylinder.

[0014] According to some embodiments, the scraping assembly further includes: a fixing ring, which is fixedly connected to the scraping air ring and connected to the second connecting ring via a flexible ring; an air supply ring, located inside the scraping air ring, on which a first connecting pipe fixedly connected to the fixing ring is fixedly installed; and a second connecting pipe, which is fixedly installed on the second connecting ring, with one end fixedly connected to the air supply cylinder and the other end slidably connected to the first connecting pipe.

[0015] According to some embodiments, the protective assembly further includes: a slide rod, slidably mounted on the second connecting ring and fixedly connected to the fixed ring; a compression column, fixedly mounted on the bottom end of the slide rod; a second spring, one end fixedly connected to the fixed ring and the other end fixedly connected to the second connecting ring; the air supply assembly further includes: a cam, fixedly mounted on the second rotating shaft.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The folding cover of the present invention, driven by dry hot air, moves the scraping air ring up and down along the outer surface of the antenna. The air supply cylinder synchronously adjusts the expansion degree of the scraping air ring to adapt to the size of different parts of the antenna. The scraping air ring completely peels off the salt frost crystal layer by the friction of the contact and the melting of the hot air. When the folding cover is fully unfolded, the scraping air ring is separated from the antenna, and the internal gas blows away the cleaned salt frost, avoiding secondary pollution, protecting the antenna surface from corrosion, and ensuring the stability of signal transmission and reception.

[0017] 2. Before cleaning the antenna, the present invention performs a sealing test on the connection between the antenna and the repeater using a sealing detection component. If hot air can push the sealing block and the sealing cover apart after being introduced, it indicates that the seal is effective; otherwise, it indicates that the seal has failed. The pressure of the first spring can also be adjusted by rotating the first shaft to adapt to different sealing test requirements, preventing salt spray from entering from the connection gap and protecting the internal electronic components from corrosion.

[0018] 3. When the second rotating shaft of the present invention rotates, it will drive the cam to squeeze the slide bar, causing the scraping air ring to move up and down while vibrating at a high frequency and a small amplitude, which enhances the peeling effect on stubborn salt deposits. After cleaning, the coil spring is released, which drives the scraping air ring to automatically reset. There is no need for staff to climb for maintenance. Moreover, by connecting an external extension pipe, staff can also perform high-altitude operations without climbing to high places, reducing the number of high-altitude operations.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0025] This invention is described in detail with reference to the accompanying drawings. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0026] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Example 1: As Figures 1 to 11 As shown, the outdoor extreme environment-adapted wireless communication relay equipment protection mechanism includes an antenna 102 installed on the wireless communication repeater 101; the outdoor extreme environment-adapted wireless communication relay equipment protection mechanism also includes a scraping component 120, a protective component 140, and an air supply component 150; wherein, the scraping component 120 includes a scraping air ring 122 for cleaning the outer surface of the antenna 102; the protective component 140 includes a folding cover 141 for driving the scraping air ring 122 to move up and down; the air supply component 150 includes an air supply cylinder 158, which controls the expansion degree of the scraping air ring 122 during the up and down movement of the scraping air ring 122, so that the scraping air ring 122 is adapted to the size of the antenna 102.

[0029] It should be noted that the wireless communication repeater 101 and antenna 102 are installed outdoors at a high altitude, unobstructed and with strong air circulation. In the extreme salt spray environment, salt spray at high altitudes will continuously adhere to the outer surface of antenna 102 with the wind. Due to the high humidity and temperature difference between day and night at high altitudes, the salt spray cannot evaporate quickly and will gradually condense and dry on the surface of antenna 102, forming a dense salt frost crystal layer. After long-term accumulation, the salt frost will corrode antenna 102, leading to signal attenuation; moreover, the salt spray will penetrate into the device through the connection gap between antenna 102 and wireless communication repeater 101, corroding the electronic components of wireless communication repeater 101 and causing equipment failure.

[0030] Every day, during designated time periods, operators use pre-installed outdoor extension pipes to introduce temperature-controlled dry hot air into the protective component 140. These extension pipes are suitable for high-altitude installations and can transport hot air over long distances. The pipes are also treated with anti-corrosion and dustproof sealing to prevent salt spray from entering the pipes and affecting the hot air delivery. After the hot air enters the protective component 140, it gradually fills the cavity, forming a stable driving force to power the movement of the second spring 144 of the drive component. At the same time, the hot air can preheat the inside of the protective component 140 to prevent salt spray from condensing inside the protective component 140 and causing the component to jam. At this time, the air supply component 150 is on standby, and the air supply cylinder 158 is in the initial adjustment state.

[0031] When the internal hot air pressure of the protective component 140 reaches a preset value, the hot air pushes the folding cover 141 to perform axial extension and retraction, which in turn drives the scraping component 120 connected to the folding cover 141 to move up and down as a whole, and finally drives the scraping air ring 122 to move axially at a uniform speed along the outer surface of the antenna 102.

[0032] Throughout the entire process of the scraping air ring 122 moving up and down, the air supply cylinder 158 inside the air supply assembly 150 works synchronously in real time to control the internal air pressure of the scraping air ring 122, thereby adjusting its expansion degree to ensure that the scraping air ring 122 is always adapted to the outer surface size of the antenna 102. When the scraping air ring 122 moves to the narrow end of the antenna 102, the air supply cylinder 158 controls the increase of the internal air pressure of the scraping air ring 122, so that the scraping air ring 122 expands synchronously to adapt to the size of the narrow end of the antenna 102, preventing insufficient expansion of the scraping air ring 122 and failure to make close contact with the surface of the antenna 102, thus affecting the cleaning effect.

[0033] Driven by the folded cover 141, the scraping air ring 122 moves up and down at a constant speed along the outer surface of the antenna 102. The cleaning layer attached to its outer surface, in a state of close contact with the surface of the antenna 102, thoroughly scrapes and adsorbs the salt frost crystal layer on the surface of the antenna 102. For loose salt frost powder and salt frost crystals, the frictional force formed by the expansion pressure of the scraping air ring 122, combined with the assistance of hot air, melts the salt frost completely off the surface of the antenna 102. When the folded cover 141 is fully unfolded, the scraping air ring 122 will detach from the antenna 102. In this way, the gas inside the folded cover 141 will directly blow away all the salt frost cleaned by the scraping air ring 122, ensuring the cleanliness of the scraping air ring 122. This not only extends the service life of the scraping air ring 122, but also prevents secondary pollution.

[0034] like Figure 2 and Figure 3 As shown, the sealing detection assembly 110 includes a first connecting half cover 111, a second connecting half cover 112, a sealing ring 113, and an air inlet pipe 114; the first connecting half cover 111 is disposed at the connection between the wireless communication repeater 101 and the antenna 102, and is connected to the second connecting half cover 112 by bolts; multiple sealing rings 113 are respectively disposed inside the first connecting half cover 111 and the second connecting half cover 112; the air inlet pipe 114 is fixedly installed on the second connecting half cover 112.

[0035] It should be noted that the first connecting half-cover 111 and the second connecting half-cover 112 have threaded grooves on their tops. The first connecting half-cover 111 and the second connecting half-cover 112 are fixed together with bolts and fixed at the connection between the wireless communication repeater 101 and the antenna 102. This prevents the connection between the wireless communication repeater 101 and the antenna 102 from being exposed to the outside world and directly affected by salt spray, which would affect the connection between the wireless communication repeater 101 and the antenna 102. Furthermore, by setting the sealing ring 113, the upper and lower ends of the wireless communication repeater 101 and the antenna 102 can be sealed to prevent salt spray from entering and form a sealed space. In addition, the air inlet pipe 114 can be connected to an external extension pipe, which is convenient for staff to directly supply air.

[0036] like Figure 3 , Figure 10 and Figure 11As shown, the unidirectional conveying assembly 130 includes a third connecting pipe 131, a fourth connecting pipe 132, a fifth connecting pipe 133, a connecting frame 134, a first rotating shaft 135, a first bevel gear 136, a second bevel gear 137, a fixing frame 138, a first screw 139, a threaded bracket 1391, a first spring 1392, a sealing block 1393, and a sealing cover 1394. The fourth connecting pipe 132 is fixedly installed on the first connecting half cover 111, and the sealing cover 1394 is fixedly installed inside the fourth connecting pipe 132. The fixing frame 138 is fixedly installed inside the fourth connecting pipe 132, and the first screw 139 is rotatably installed on the fixing frame 138. The threaded bracket 1391 is threadedly connected to the first screw 139. 1. It is slidably connected to the fixed frame 138; the sealing block 1393 is used to seal the sealing cover 1394, and the sealing block 1393 is connected to the threaded frame 1391 through the first spring 1392; the first rotating shaft 135 is rotatably mounted on the fourth connecting pipe 132, and the first bevel gear 136 is fixedly mounted on the first rotating shaft 135; the second bevel gear 137 is fixedly mounted on the first screw 139, and the second bevel gear 137 meshes with the first bevel gear 136; the fifth connecting pipe 133 is slidably mounted on the fourth connecting pipe 132, and the third connecting pipe 131 is provided above the fifth connecting pipe 133; one end of the connecting frame 134 is fixedly connected to the sealing block 1393, and the other end of the connecting frame 134 is fixedly connected to the fifth connecting pipe 133.

[0037] It should be noted that when hot air is supplied from the air inlet pipe 114, the supplied hot air will enter the first connecting half-cover 111 and the second connecting half-cover 112. Due to the sealing of the sealing ring 113, a sealed space is formed between the first connecting half-cover 111 and the second connecting half-cover 112. In this way, the gas can only enter the fourth connecting pipe 132 and act on the sealing block 1393 in the fourth connecting pipe 132. If the gas cannot separate the sealing block 1393 from the sealing cover 1394 as the gas is continuously supplied, it indicates that the seal between the first connecting half-cover 111 and the second connecting half-cover 112 has failed. This is not conducive to the protection of the connection between the wireless communication repeater 101 and the antenna 102. In this way, the connection between the wireless communication repeater 101 and the antenna 102 can be checked before each cleaning when the scraping air ring 122 is moved upward, so as to avoid the antenna 102 becoming unusable due to damage to the connection caused by salt spray.

[0038] Furthermore, if the first connecting half-cover 111 and the second connecting half-cover 112 are properly sealed, the gas will directly separate the sealing block 1393 and the sealing cover 1394. In this way, the sealing block 1393 will move upward. The upward movement of the sealing block 1393 will cause the fifth connecting pipe 133 to move upward through the connecting bracket 134. The upward movement of the fifth connecting pipe 133 will connect with the third connecting pipe 131. In this way, the third connecting pipe 131 and the fourth connecting pipe 132 are connected without leakage, which can effectively deliver the gas into the folding cover 141 and continuously inject gas into the folding cover 141 until the folding cover 141 unfolds and drives the scraping air ring 122 to move upward for cleaning.

[0039] Furthermore, by rotating the first rotating shaft 135, the first screw 139 can be rotated by means of the first bevel gear 136 and the second bevel gear 137. The first screw 139 can drive the threaded frame 1391 to move, so that the threaded frame 1391 can squeeze or release the first spring 1392. If the first spring 1392 is squeezed, the pressure exerted by the sealing block 1393 on the sealing cover 1394 will be greater, and the required air pressure impact separation force will also be greater. If the first spring 1392 is released, the pressure exerted by the sealing block 1393 on the sealing cover 1394 will be less, and the required air pressure impact separation force will also be less. This allows for more effective testing of the seals at the first connecting half cover 111 and the second connecting half cover 112 to different degrees according to actual testing needs, and to test whether the seals at the first connecting half cover 111 and the second connecting half cover 112 meet the standards.

[0040] like Figure 4 and Figure 6 As shown, the protective assembly 140 includes a folding cover 141, a first connecting ring 142, a second connecting ring 143, a second spring 144, a slide rod 145, and a compression post 146; the folding cover 141 is threadedly connected to the first connecting half cover 111 and the second connecting half cover 112, and the folding cover 141 is fixedly connected to the third connecting pipe 131; the first connecting ring 142 is fixedly installed inside the folding cover 141; the second connecting ring 143 is fixedly installed on the top of the folding cover 141.

[0041] It should be noted that the gas entering the third connecting pipe 131 will enter the folded cover 141. As the gas continues to enter, it will fill the folded cover 141. Since the scraping gas ring 122 is initially expanded and in close contact with the antenna 102, a sealed space will be formed from the folded cover 141 to the scraping gas ring 122. This sealed space will continuously expand under the action of the gas, allowing the scraping gas ring 122 to clean the outer surface of the antenna 102.

[0042] like Figures 4 to 8As shown, the air supply assembly 150 includes a second rotating shaft 151, a winding frame 152, a pull rope 153, a positioning frame 154, a power storage box 155, a cam 156, a coil spring 157, an air supply cylinder 158, a pressing plate 159, and a second screw 1591. The winding frame 152 is fixedly mounted on the second connecting ring 143, and the second rotating shaft 151 is rotatably mounted on the winding frame 152. The pull rope 153 is wound around the second rotating shaft 151, and one end of the pull rope 153 is fixedly connected to the first connecting ring 142. The power storage box 155 is fixedly mounted on the winding frame 152, and the power storage box 155 is connected to the second rotating shaft 151. The second rotating shaft 151 is rotatably connected; the coil spring 157 is disposed inside the power storage box 155, one end of the coil spring 157 is fixedly connected to the second rotating shaft 151, and the other end of the coil spring 157 is fixedly connected to the power storage box 155; the positioning frame 154 is fixedly installed on the power storage box 155, and the air supply cylinder 158 is fixedly installed on the positioning frame 154; the second screw 1591 is rotatably installed on the air supply cylinder 158, and the second screw 1591 is fixedly connected to the second rotating shaft 151; the extrusion plate 159 is threadedly connected to the second screw 1591, and the extrusion plate 159 is slidably connected to the air supply cylinder 158.

[0043] like Figure 9 As shown, the scraping assembly 120 includes a fixing ring 121, a scraping air ring 122, an air supply ring 123, a first connecting pipe 124, a second connecting pipe 125, and a flexible ring 126. The fixing ring 121 is fixedly connected to the scraping air ring 122, and the fixing ring 121 is connected to the second connecting ring 143 through the flexible ring 126. The air supply ring 123 is located inside the scraping air ring 122, and the first connecting pipe 124, which is fixedly connected to the fixing ring 121, is fixedly installed on the air supply ring 123. The second connecting pipe 125 is fixedly installed on the second connecting ring 143, one end of the second connecting pipe 125 is fixedly connected to the air supply cylinder 158, and the other end of the second connecting pipe 125 is slidably connected to the first connecting pipe 124.

[0044] It should be noted that when the second connecting ring 143 begins to drive the scraping air ring 122 upward, the pull rope 153 is released. As the pull rope 153 is released, the second rotating shaft 151 rotates continuously. The rotation of the second rotating shaft 151 first causes the coil spring 157 to coil and store energy. Then, it drives the second screw 1591 to rotate. Since the second screw 1591 has a reverse thread, the extrusion plate 159 extrudes the gas in the air supply cylinder 158, causing the gas to enter the air supply ring 123 through the second connecting pipe 125 and the first connecting pipe 124. The gas is then evenly distributed to all parts of the scraping air ring 122 through the air supply ring 123, allowing the scraping air ring 122 to expand synchronously. This prevents uneven expansion and ensures the scraping air ring 122 adheres better to the antenna 102. Even as the scraping air ring 122 moves upward and the size of the antenna 102 decreases, the pressure of the scraping air ring 122 on the antenna 102 remains constant, allowing the scraping air ring 122 to better clean the outer surface of the antenna 102. After cleaning, the air supply is stopped, causing the sealing block 1393 to lose its compression. This causes the fifth connecting pipe 133 to separate from the third connecting pipe 131, releasing the gas inside the folding cover 141. Due to the loss of gas drive, the coil spring 157 is also released, causing the second rotating shaft 151 to rotate in the opposite direction and rewind the pull rope 153. This pulls the scraping air ring 122 downward to return to its original position. During this process, the reverse rotation of the second rotating shaft 151 also causes the compression plate 159 to continuously retract the gas supplied to the scraping air ring 122 for continued use next time.

[0045] The working principle of this embodiment: Workers connected the air inlet pipe 114 of the sealing test component 110 through an external extension pipe and introduced dry hot air to first perform a sealing test on the connection between the wireless communication repeater 101 and the antenna 102.

[0046] Hot air enters the sealed space formed by the first connecting half-cover 111 and the second connecting half-cover 112. If the seal is effective, the hot air will enter the fourth connecting pipe 132, pushing the sealing block 1393 to overcome the elastic force of the first spring 1392 and separate from the sealing cover 1394. The sealing block 1393 drives the fifth connecting pipe 133 to move upward through the connecting bracket 134, and connects with the third connecting pipe 131, so that the hot air can be smoothly delivered to the protective component 140. If the seal fails, the hot air cannot push the sealing block 1393, indicating that the seal at the connection is damaged and needs to be maintained in time.

[0047] The first screw 139 can be rotated by rotating the first shaft 135, which drives the first bevel gear 136 to mesh with the second bevel gear 137; the threaded frame 1391 slides to compress or release the first spring 1392, adjusting the initial pressure of the sealing block 1393 to adapt to different sealing detection requirements.

[0048] Hot air enters the folding cover 141 through the third connecting pipe 131, pushing the folding cover 141 to unfold axially, causing the second connecting ring 143, the fixing ring 121 and the scraping air ring 122 to move upward at a constant speed along the outer surface of the antenna 102.

[0049] When the folding cover 141 is unfolded, the first connecting ring 142 pulls the pull rope 153, causing the second rotating shaft 151 to rotate, and the coil spring 157 coils up to store power; at the same time, the second rotating shaft 151 drives the second screw 1591 to rotate, and the extrusion plate 159 extrudes the gas in the air supply cylinder 158. The gas is transported to the air supply ring 123 through the second connecting pipe 125 and the first connecting pipe 124, and is evenly injected into the scraping air ring 122 to adjust its expansion degree so that it always fits the size of different parts of the antenna 102; during the movement, the scraping air ring 122, through the friction of contact and the assistance of hot gas, melts and peels off the salt frost crystal layer on the surface of the antenna 102.

[0050] When the folding cover 141 is fully unfolded, the scraping air ring 122 detaches from the antenna 102, and the gas inside the folding cover 141 is quickly ejected, blowing away the scraped salt frost and preventing secondary pollution.

[0051] After cleaning, the gas supply is stopped, the sealing block 1393 resets under the action of the first spring 1392, the fifth connecting pipe 133 separates from the third connecting pipe 131, and the gas in the folding cover 141 is released; the coil spring 157 releases its stored force, driving the second rotating shaft 151 to rotate in the opposite direction, winding the pull rope 153, pulling the folding cover 141 to retract and reset, and the scraping gas ring 122 moves down along the antenna 102 to return to its initial position; at the same time, the second rotating shaft 151 drives the second screw 1591 to rotate in the opposite direction, the extrusion plate 159 resets, and the gas in the scraping gas ring 122 is retracted for the next use.

[0052] Example 2: As Figures 4 to 6 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that: The slide rod 145 is slidably mounted on the second connecting ring 143, and the slide rod 145 is fixedly connected to the fixed ring 121; the extrusion column 146 is fixedly mounted on the bottom end of the slide rod 145; one end of the second spring 144 is fixedly connected to the fixed ring 121, and the other end of the second spring 144 is fixedly connected to the second connecting ring 143; the cam 156 is fixedly mounted on the second rotating shaft 151.

[0053] The working principle of this embodiment: When the second rotating shaft 151 starts to rotate, it will drive the cam 156 to rotate. The rotation of the cam 156 will squeeze the squeezing column 146, causing the slide rod 145 and the second spring 144 to vibrate up and down continuously. This will drive the fixed ring 121 connected to it, so that the scraping air ring 122 will vibrate at a high frequency and a small amplitude as it moves upward along the antenna 102, thus achieving vibration-type cleaning. This will enhance the removal effect of salt spray crystals and stubborn dust on the surface of the antenna 102 and improve the cleaning effect.
