Description

Technical Field

[0001] The present invention relates to the technical field of antenna protective covers, and in particular to a antenna cover and a base station antenna. Background Art

[0002] The fifth generation of mobile communication technology is the latest generation of cellular mobile communication technology, which is an extension of 4G, 3G and 2G systems. The performance goals of 5G are high data rate, reduced latency, energy saving, cost reduction, increased system capacity and large-scale device connection.

[0003] Existing base station antennas are generally divided into indoor antennas and outdoor antennas. Outdoor base station antennas are further divided into omnidirectional antennas and directional antennas. In practical applications, directional antennas are more widely used than omnidirectional antennas. Directional antennas generally look like a board, so they are also called plate antennas. Plate antennas are mainly composed of radiation units (diopter), reflectors (bottom plates), power distribution networks (feeding networks), and packaging protection (radomes).

[0004] In order to make the signal coverage of the outdoor base station antenna wider, the antenna is usually installed at a high place. Therefore, it is easy for birds to stand on the antenna. Birds standing on the antenna cover to defecate easily cause bird droppings to accumulate on the antenna cover, affecting the heat dissipation of the antenna. After the bird droppings accumulate, bacteria breed in the bird droppings, which easily leads to aging and damage of the antenna cover shell. Many base station antennas are installed on the top of the mountain. There are more birds in the mountains and forests, so it is more likely to cause the above-mentioned problem of bird droppings accumulating on the antenna cover. And because the antenna cover is installed at a high altitude, it is very inconvenient to manually clean the surface of the antenna cover.

[0005] After searching, it was found that the Chinese invention patent with application number: CN202010891185.5 and titled "A 5G base station antenna cover" has proposed a solution to the above problem. However, the solution of this patent is designed for cylindrical omnidirectional antennas, and does not design plate antennas. And because plate antennas are generally tilted, plate antennas are more likely to allow bird droppings to accumulate on their surfaces than omnidirectional antennas.

[0006] To this end, a radome and a base station antenna are proposed. Summary of the invention

[0007] The object of the present invention is to provide a radome and a base station antenna to solve the problem in the above background technology that the accumulation of bird droppings on the radome affects the life of the radome and the heat dissipation of the antenna.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A antenna cover and a base station antenna, comprising a shell body, the interior of the shell body is hollow, the bottom of the shell body is provided with an opening, a sealing plate is detachably installed at the opening, and the upper and lower sides of the back side of the shell body are provided with connecting parts for fixing the shell; a guide groove is provided on the shell body, and a cleaning component is provided on the shell body, and the cleaning component comprises a cleaning ring slidably sleeved on the outside of the shell body, the cleaning ring is used to slidably scrape the outer wall of the shell body, a guide block is provided on the cleaning ring corresponding to the guide groove, the guide block is slidably installed in the guide groove, a guide column is fixed on the upper side of the guide groove of the guide groove, a steel cable is fixedly connected to the guide block, a counterweight block is also slidably installed in the guide groove, one end of the steel cable away from the guide block bypasses the guide column and is fixedly connected to the counterweight block, the counterweight block is used to pull the cleaning ring and keep the cleaning ring at the upper end of the guide groove, and the shell body is also provided with a driving component for pushing the cleaning ring downward along the guide groove.

[0010] The driving assembly drives the cleaning ring to move downward, and the cleaning ring scrapes the side wall of the outer shell body when sliding, keeping the outside of the outer shell body clean, avoiding the accumulation of bird droppings on the outside of the outer shell body, avoiding the accumulation of bird droppings on the outside of the outer shell body and affecting the heat dissipation of the antenna inside the antenna cover, and also avoiding the problem of aging and damage of the antenna cover caused by bird droppings accumulation, thereby ensuring the service life of the antenna cover.

[0011] When the driving assembly no longer drives the cleaning ring to move downward, the counterweight slides downward along the guide groove under the action of its own gravity, and the cleaning ring is pulled upward by the counterweight under the pulling of the steel cable, and the cleaning ring is reset.

[0012] Preferably, the upper surface of the cleaning ring is perpendicular to the side surface of the outer shell body, and the driving assembly includes a water storage portion arranged on the cleaning ring, the water storage tank is located on the cleaning ring on the front side of the outer shell body, a drain outlet is provided at the bottom of the water storage portion, a cover plate for closing the drain outlet is rotatably provided at the drain outlet, a support rod is fixedly installed on the lower side of the outer shell body, a push rod is fixed on the support rod corresponding to the drain outlet, and when the cleaning ring slides down to the bottom along the guide groove, the push rod lifts the cover plate upward and opens the drain outlet.

[0013] The water storage part is used to store rainwater. When it rains, rainwater will enter the water storage part and be collected. As the rainwater is continuously collected, the weight of the rainwater also increases. Finally, when the weight of the rainwater and the cleaning ring is greater than the weight of the counterweight, the cleaning ring moves downward under the action of gravity, and the counterweight is pulled upward. When the cleaning ring moves downward, it will scrape and clean the side of the shell body. When the cleaning ring moves downward to the limit position, the top rod on the shell body will push the cover plate upward, the drain port is opened, and the water stored in the water storage part is discharged from the drain port. Because the weight of the cleaning ring becomes lighter after the water in the water storage part is discharged, the cleaning ring is pulled upward by the counterweight. At this time, under the action of the gravity of the cover plate, the cover plate closes the drain port again. The water storage part resumes the water storage function. In this way, the cleaning ring can be driven by natural factors to clean the shell body without adding additional power, which helps to save costs.

[0014] In addition, by utilizing the rainy period, during the process of storing water inside the water storage part, the rainwater soaks the bird droppings and dust on the outer shell body, which helps to facilitate the scraping of the bird droppings and dust by the cleaning ring, thereby improving the cleaning effect.

[0015] Preferably, a fixing ring is also fixed on the cleaning ring, and the fixing ring surrounds the outside of the outer shell body. A ring groove is opened on the outer wall of the fixing ring, and a swivel is rotatably installed inside the ring groove. A bird-repelling rod is fixedly installed on the swivel, and the bird-repelling rod is facing the top of the outer shell body.

[0016] In general, the plate antenna is installed at an inclined angle to the vertical direction, and the bird-repellent stick is also installed at an inclined angle along with the outer shell. When a bird stands on the bird-repellent stick, the swivel will start to rotate due to uneven force. When the bird-repellent stick rotates, it can scare away the birds on the top of the outer shell and the birds standing on the bird-repellent stick, preventing the birds from staying on the antenna cover, thereby helping to reduce the possibility of birds defecation above the antenna cover and bird droppings sticking to the antenna cover.

[0017] Because the driving assembly relies on rainwater to drive, the shell body cannot be scratched on non-rainy days. The setting of the bird repellent stick can drive away birds on non-rainy days to prevent a large amount of bird droppings from accumulating on the shell body. It can avoid the situation where the cleaning ring is difficult to clean after excessive accumulation of bird droppings, and ensure the stability of the cleaning ring.

[0018] Preferably, the upper and lower sides of the counterweight block are both provided with inclined guide parts, and the bottom of the guide groove is provided with an inclined drainage part. The guide part on the counterweight block makes the counterweight block look like an isosceles trapezoid, and the drainage part is inclined downward. The guide part and the drainage part can prevent bird droppings, dust, leaves and other debris from accumulating inside the guide groove. The counterweight block can remove dust, leaves and other debris from the inside of the guide groove when it moves.

[0019] Preferably, a plurality of blades are fixedly mounted on the outer wall of the rotating ring, and the plurality of blades are evenly distributed around the circumference and mounted on the fixed ring, and each blade is perpendicular to the end face of the rotating ring. The arrangement of the blades can utilize wind energy to drive the bird-repelling rod, so that the bird-repelling rod is no longer driven only by the gravity of the birds, and the antenna cover is generally arranged at a high place, where there are abundant wind resources, and when the blades are blown by the wind, the rotating ring and the bird-repelling rod can be driven by the wind to activate the bird-repelling function, which reduces the activation conditions of the bird-repelling function of the bird-repelling rod and helps to improve the bird-repelling efficiency and effect of the bird-repelling rod.

[0020] The arrangement of the blades enables the bird-repelling rod to be effectively driven by wind energy even when the antenna cover is in a vertical state (that is, the shell body is in a vertical state), thereby reducing the limitations of the use of the bird-repelling rod.

[0021] Preferably, a bird-repelling ball is fixedly installed on the top of the bird-repelling stick, the interior of the bird-repelling ball is hollow, and a plurality of collision balls are placed inside the bird-repelling ball. A paddle is fixedly installed on the shell body, and the paddle is a bendable and deformable plastic sheet. When the bird-repelling ball collides with the paddle, the collision balls are driven to collide with each other and make a sound.

[0022] The bird-repelling ball rotates along with the bird-repelling rod. When the bird-repelling ball passes the position of the paddle, the paddle collides with the bird-repelling ball. The paddle is deformed after the collision and avoids the bird-repelling ball, so that the bird-repelling ball can pass the paddle without getting stuck. When the paddle collides with the bird-repelling ball, the collision balls inside the bird-repelling ball also collide with each other and the collision balls also collide with the inner wall of the bird-repelling ball. The collision of the collision balls will make a sound, and the sound can be used to drive away the birds. Further, birds are prevented from excreting and nesting on the antenna cover, and bird droppings are prevented from accumulating outside the antenna cover, thereby ensuring the service life of the antenna cover and the heat dissipation efficiency of the antenna inside the antenna cover.

[0023] Preferably, a plurality of balls are arranged between the inner ring of the rotating ring and the annular groove, and the plurality of balls are evenly distributed between the inner ring of the rotating ring and the annular groove with the inner ring axis as the reference circumference. The balls convert the sliding friction between the inner ring of the rotating ring and the annular groove into rolling friction, which helps to reduce the resistance encountered when the rotating ring rotates, so that the rotating ring can rotate with a smaller driving force, thereby reducing the starting conditions of the rotating ring, and further reducing the bird-repelling starting conditions of the bird-repelling ball and the bird-repelling stick. The bird-repelling effect is further improved, and birds are prevented from defecating and nesting on the antenna cover.

[0024] Preferably, the surface of the paddle is provided with a vibration part, which is a plurality of evenly spaced protrusions. The setting of the vibration part allows the bird-repelling ball to further impact and vibrate the bird-repelling ball by utilizing the rebound force of the paddle itself and the uneven surface of the vibration part when colliding with the paddle, so that the vibration amplitude and frequency of the collision ball inside the bird-repelling ball are higher, thereby increasing the sound emitted by the bird-repelling ball, which helps to further disperse the birds. Prevent birds from standing on the antenna cover to defecate, and prevent birds from nesting on the antenna cover.

[0025] A base station antenna comprises the above-mentioned antenna cover, and also comprises a base plate, a vibrator and a feeding network. The base plate is fixedly installed inside the outer shell body of the antenna cover. There are multiple vibrators, and the multiple vibrators are evenly fixed on the base plate. One side of the base plate where the vibrator is located faces the front direction of the antenna cover body. The feeding network is fixedly arranged at the bottom of the base plate, and the interface of the feeding network extends through the sealing plate to the outside of the antenna cover body.

[0026] The antenna is protected inside by the antenna cover, which effectively ensures the heat dissipation effect of the antenna, thereby ensuring the stability of the signal transmission of the antenna. Since the bird droppings are prevented from affecting the aging of the antenna cover, the service life of the antenna cover is increased. Therefore, it is also avoided that the antenna is damaged due to rainwater contacting the antenna after the antenna cover is damaged, thereby also improving the service life of the antenna.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. An antenna cover designed by the present invention is provided with a cleaning ring which is slidably arranged on the outer shell body. The driving assembly is used to drive the cleaning ring to move downward to scrape the outer part of the outer shell body, thereby keeping the outer part of the outer shell body clean, avoiding the accumulation of bird droppings on the outer part of the outer shell body, avoiding the accumulation of bird droppings on the outer part of the outer shell body to affect the heat dissipation of the antenna inside the antenna cover, and also avoiding the problem of aging and damage of the antenna cover caused by the accumulation of bird droppings, thereby ensuring the service life of the antenna cover.

[0029] 2. The antenna cover designed by the present invention is also provided with a swivel, a bird-repelling stick and a bird-repelling ball on the cleaning ring. The bird-repelling stick and the bird-repelling ball are used to drive away birds, so as to prevent birds from standing on the antenna cover to defecate and build nests on the antenna cover, thereby further ensuring the service life of the antenna and preventing the accumulation of bird droppings from affecting the heat dissipation of the antenna inside the antenna cover.

[0030] 3. A base station antenna designed by the present invention utilizes the above-mentioned antenna cover to protect the antenna inside, which effectively ensures the heat dissipation effect of the antenna, and further ensures the stability of the signal transmission of the antenna. Since the influence of bird droppings on the aging of the antenna cover is avoided, the service life of the antenna cover is increased. Therefore, the situation in which the antenna is damaged due to the contact of rainwater with the antenna after the antenna cover is damaged and the antenna is damaged is avoided, thereby also improving the service life of the antenna.

DETAILED DESCRIPTION

[0040] See also Figures 1 to 8 The present invention provides a radome and a base station antenna, and the technical solution is as follows:

[0041] A radome, comprising a shell body 1, wherein the interior of the shell body 1 is hollow, an opening 2 is provided at the bottom of the shell body 1, a sealing plate 3 is detachably installed at the opening 2, and a connecting portion 4 for fixing the shell is provided on both the upper and lower sides of the back of the shell body 1; a guide groove 5 is provided on the shell body 1, and a cleaning assembly is provided on the shell body 1, wherein the cleaning assembly comprises a cleaning ring 6 slidably sleeved on the outside of the shell body 1, the upper surface of the cleaning ring 6 is perpendicular to the side surface of the shell body 1, and the cleaning ring 6 is used to clean the outer surface of the shell body 1. The side wall is slidably scraped, and a guide block 7 is provided on the cleaning ring 6 corresponding to the guide groove 5. The guide block 7 is slidably installed inside the guide groove 5. A guide column 8 is fixed on the upper side of the guide groove 5. A steel cable 9 is fixedly connected to the guide block 7. A counterweight 10 is also slidably installed inside the guide groove 5. The end of the steel cable 9 away from the guide block 7 bypasses the guide column 8 and is fixedly connected to the counterweight 10. The upper and lower sides of the counterweight 10 are provided with inclined guide parts 20. The guide parts 20 on the counterweight 10 make the counterweight 10 look like an isosceles trapezoid. An inclined sewage discharge part 21 is provided at the bottom of the guide groove 5, and the sewage discharge part 21 is inclined downward. The counterweight 10 is used to pull the cleaning ring 6 and keep the cleaning ring 6 at the upper end of the guide groove 5. The shell body 1 is also provided with a driving component for pushing the cleaning ring 6 downward along the guide groove 5.

[0042] refer to Figure 1 , Figure 4 , Figure 6 as well as Figure 7 The driving assembly includes a water storage portion 11 arranged on the cleaning ring 6, and the water storage tank is located on the cleaning ring 6 on the front side of the shell body 1. A drain outlet 12 is opened at the bottom of the water storage portion 11, and a cover plate 13 for closing the drain outlet 12 is rotatably arranged at the drain outlet 12. A support rod 14 is fixedly installed on the lower side of the shell body 1, and a push rod 15 is fixed on the support rod 14 corresponding to the drain outlet 12. When the cleaning ring 6 slides down to the bottom along the guide groove 5, the push rod 15 pushes the cover plate 13 upward and opens the drain outlet 12.

[0043] refer to Figure 1 , Figure 4 , Figure 5 as well as Figure 7A fixing ring 16 is also fixed on the cleaning ring 6. The fixing ring 16 surrounds the outside of the shell body 1. An annular groove 17 is provided on the outer wall of the fixing ring 16. A rotating ring 18 is rotatably installed inside the annular groove 17. A plurality of balls 26 are arranged between the inner ring of the rotating ring 18 and the annular groove 17. The plurality of balls 26 are evenly distributed between the inner ring of the rotating ring 18 and the annular groove 17 with the inner ring axis as the reference circumference. A plurality of blades 22 are also fixedly installed on the outer wall of the rotating ring 18. The plurality of blades 22 are evenly distributed on the fixing ring 16. Each blade 22 is perpendicular to the end face of the rotating ring 18. A bird-repelling rod 19 is fixedly installed on the rotating ring 18. The bird-repelling rod 19 faces the top of the shell body 1. A bird-repelling ball 23 is fixedly installed on the top of the bird-repelling rod 19. The interior of the bird-repelling ball 23 is hollow. A plurality of collision balls 24 are placed inside the bird-repelling ball 23. A paddle 25 is fixedly installed on the shell body 1. A vibration part 27 is provided on the surface of the paddle 25. The vibration part 27 is a plurality of evenly spaced protrusions. The paddle 25 is a bendable and deformable plastic sheet.

[0044] When installing, refer to Figure 2 The shell body 1 is fixedly mounted on the mounting column 31 through the connecting plate 32, and the shell body 1 and the mounting column 31 are installed at an inclination angle of α. In this embodiment, the angle α is selected to be 30°.

[0045] When using, refer to Figure 1 In the initial state, the counterweight 10 pulls the cleaning ring 6 through the steel cable 9 under the action of gravity and keeps the cleaning ring 6 always at the upper end of the guide groove 5, and the cover plate 13 also closes the drain port 12 under the action of its own gravity. When it rains, rainwater falls into the water storage part 11 and accumulates inside the water storage part 11. At this time, rainwater will also fall on the shell body 1, and the rainwater will soak and soften the bird droppings, dust, etc. adhered to the shell body 1. As rainwater continues to accumulate in the water storage part 11, when the total mass on the cleaning ring 6 is greater than the mass of the counterweight 10, the cleaning ring 6 begins to slide downward, and the counterweight 10 slides upward driven by the steel cable 9. When the cleaning ring 6 slides downward, it scrapes the side of the shell body 1 to scrape off the dust, bird droppings and other debris on the outside of the shell body 1.

[0046] When the cleaning ring 6 slides down to the lowest position, refer to Figure 1 , Figure 6 and Figure 7, the cover plate 13 will abut against the top rod 15 below, and the top rod 15 will push the cover plate 13 upward from the bottom and open the drain port 12. At this time, the rainwater accumulated in the water storage part 11 will be discharged from the drain port 12 outside the water storage part 11. After the cleaning ring 6 loses the weight of the rainwater, the overall weight decreases. When the weight of the cleaning ring 6 is lower than the weight of the counterweight 10, the counterweight 10 will pull the cleaning ring 6 upward to reset the cleaning ring 6. After the rainwater is completely discharged from the drain port 12, the cover plate 13 rotates again under its own gravity to close the drain port 12. At this time, the water storage part 11 can accumulate rainwater again. In this way, rainwater can be used as power to clean the antenna cover back and forth.

[0047] In normal times, refer to Figure 2 Since the shell body 1 and the mounting column 31 are installed at an angle, and the cleaning ring 6 is perpendicular to the shell body 1, the cleaning ring 6 is also inclined with respect to the horizontal plane. At this time, if a bird stands on the bird-repelling rod 19 and the bird-repelling ball 23, the imbalance of the swivel 18 caused by the weight of the bird will cause the swivel 18 to start rotating, making it impossible for the bird to stand on the bird-repelling rod 19 and the bird-repelling ball 23. The rotation of the bird-repelling rod 19 and the bird-repelling ball 23 can also scare the birds standing on the top of the antenna cover or on the connecting plate 32 and the mounting column 31, and drive the birds away.

[0048] In addition, refer to Figure 4 , Figure 5 as well as Figure 7 When the bird-repelling ball 23 rotates, it will pass through the paddle 25. The rotation of the bird-repelling ball 23 will collide with the paddle 25, and then the collision balls 24 inside the bird-repelling ball 23 will collide with each other to produce sound. The sound can also be used to scare and drive away birds, prevent birds from standing on the antenna cover to defecate, and prevent birds from building nests on the antenna cover.

[0049] refer to Figure 7 The blades 22 are additionally provided on the outside of the swivel 18. When the blades 22 are blown by the wind, the swivel 18 will be driven to rotate. The rotation of the swivel 18 will drive the bird-repelling ball 23 to rotate together, so that the bird-repelling ball 23 will continuously collide with the paddle 25, thereby further increasing the sound frequency of the bird-repelling ball 23, further improving the bird-repelling effect, and preventing birds from standing on the antenna cover to defecate, and preventing birds from building nests on the antenna cover.

[0050] A base station antenna, reference Figures 1 to 8, including the above-mentioned antenna cover, and also including a base plate 28, a vibrator 29 and a feeding network 30. The base plate 28 is fixedly installed inside the outer shell body 1 of the antenna cover by bolts. There are multiple vibrators 29, and the multiple vibrators 29 are evenly fixed on the base plate 28. One side of the base plate 28 where the vibrator 29 is located faces the front direction of the antenna cover body. The feeding network 30 is fixedly arranged at the bottom of the base plate 28, and the interface of the feeding network 30 extends through the sealing plate 3 to the outside of the antenna cover body.

[0051] When using, refer to Figure 1 and Figure 8 The antenna is protected inside by the antenna cover, which effectively ensures the heat dissipation effect of the antenna, thereby ensuring the stability of the signal transmission of the antenna. Since the bird droppings are prevented from affecting the aging of the antenna cover, the service life of the antenna cover is increased. Therefore, it is also avoided that the antenna is damaged due to rainwater contacting the antenna after the antenna cover is damaged, thereby also improving the service life of the antenna.
