Description

Technical Field

[0001] This invention relates to the field of base station antenna technology, specifically to a miniaturized 5G base station antenna. Background Technology

[0002] Base station antennas are crucial connecting bridges in mobile communication equipment, and their quality directly impacts the communication quality of mobile devices. Currently, MIMO (Multi-input Multi-output) technology, which employs multiple radiating elements for signal transmission and reception, is one of the key technologies of 5G and has attracted significant industry attention. MIMO technology utilizes numerous array antennas in the base station transceiver to achieve greater wireless data throughput and connection reliability. Compared to previous single / dual polarized antennas and 4 / 8 channel antennas, massive MIMO technology can improve spectrum and energy utilization efficiency through different dimensions (spatial domain, time domain, frequency domain, polarization domain, etc.). 3D shaping and channel prediction technologies can adaptively adjust the phase and power of each antenna element, significantly improving the beam pointing accuracy of the system and concentrating signal strength in specific pointing areas and specific user groups. While enhancing user signals, it can significantly reduce self-interference and neighboring cell interference within the cell, thus becoming an excellent technology for improving the carrier ratio of user signals. 5G communication base stations emit high-frequency radio waves, making communication faster and smoother. Because high-frequency radio waves can cause attenuation, 5G communication coverage is dense. Base stations are usually installed in high locations such as buildings or mountains. Affected by seasonal weather, base station antennas are easily damaged by external wind, frost, rain, snow, etc. At the same time, the heat dissipation capacity of existing communication base station antennas is poor and their self-cleaning ability is weak, increasing equipment maintenance costs.

A drive tube is rotatably connected to the surface of the fixed shaft. A push mechanism connected to the power module is fixedly connected to the surface of the drive tube. A sealing cover is hinged to the top of the window frame. The end of the push mechanism away from the drive tube is fixedly connected to the surface of the sealing cover. The push mechanism includes a support arm fixedly connected to the surface of the drive tube. An auxiliary push arm is rotatably connected to the end of the support arm away from the drive tube via a pivot.

[0009] Preferably, the rainwater collection module includes a water collection umbrella, which is inverted umbrella-shaped. A pole is fixedly connected to the mounting rod in the middle of the water collection umbrella. Multiple ropes are fixedly connected to the edge of the water collection umbrella around the pole. A water-absorbing sponge is provided on the surface formed by the ropes. A water storage tank with a filter module installed and connected to the infusion pipe is provided at the bottom of the water collection umbrella. A mechanical level gauge is provided in the water storage tank.

[0010] Preferably, the constricted section of the protective shell is provided with an air inlet pipe that connects the inside and outside of the protective shell.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Rainwater is collected by a water-collecting umbrella, and then initially filtered by an absorbent sponge. The rainwater is then filtered again by a filter module in a water storage tank to ensure the cleanliness of the rainwater entering the storage tank and the cleanliness of the rainwater entering the atomizing nozzle through the infusion tube. This reduces the amount of water used to cool the base station antenna while improving the cooling effect.

[0016] 2. The air inlet duct and louvers of the protective shell are designed to reduce the amount of air entering the shell by tilting the air inlet duct outwards. The opening and closing of the louvers, combined with the sealing cover, controls the airflow into and out of the protective shell, and controls the direction of airflow into the shell. Combined with the shape of the protective shell, the rotation of the shell creates a pressure difference between the inside and outside. When cooling is needed, air enters through the air inlet duct and exits through the louvers. The air carries away heat as it circulates, improving the heat dissipation effect.

[0017] 3. When the protective shell rotates, it drives the cleaning brush of the heat dissipation cleaning module to rotate, thereby cleaning the dust attached to the base station antenna, keeping the base station antenna clean, and ensuring that the heat generated by the base station antenna during operation can be quickly exchanged with the surrounding air.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1:

[0029] like Figure 1-8 The miniaturized 5G base station antenna shown includes a base station antenna 4 located in the middle of a mounting rod 2. A heat dissipation and cleaning module 3 that wraps around the base station antenna 4 is rotatably connected to the middle of the mounting rod 2. A rainwater collection module 6 that cooperates with the heat dissipation and cleaning module 3 is threadedly connected to the top of the mounting rod 2. A power module 7 that is connected to the heat dissipation and cleaning module 3 is threadedly connected to the mounting rod 2.

[0030] The heat dissipation and cleaning module 3 includes a protective shell 305 with an annular cross-section. The diameter of the protective shell 305 gradually decreases from the end near the rainwater collection module 6 to the lower end near the base station antenna 4, and the diameter of the protective shell 305 decreases sharply from the lower end of the base station antenna 4 to the end of the protective shell 305. Multiple cleaning brushes 301 are arranged circumferentially inside the protective shell 305. The cleaning brushes 301 are elongated and arranged along the axial direction of the mounting rod 2. The cleaning brushes 301 are interference-fitted with the base station antenna 4. Multiple heat dissipation modules 302 are arranged circumferentially inside the protective shell 305. The heat dissipation modules 302 are arranged at intervals with the cleaning brushes 301. The heat dissipation modules 302 are elongated and arranged along the axial direction of the mounting rod 2.

[0031] The protective shell 305 has a trapezoidal cross-section that is wider at the top and narrower at the bottom. Its upper and lower ends are rotatably connected to the mounting rod 2 through sealed bearings. The protective shell 305 is provided with multiple window frames that allow communication between the inside and outside. The window frames are provided with louvers 306. On the outer side of the protective shell 305, there are multiple fan blade modules 5 arranged at intervals along the axial direction of the mounting rod 2 in the area between every two louvers 306. The fan blade module 5 includes a rotating shaft that is rotatably connected to the protective shell 305, and also includes a fan blade 501 provided at the top of the rotating shaft. The distance from the top of each fan blade 501 to the protective shell 305 is distributed in a sinusoidal curve along the axial direction of the mounting rod 2 and in a sinusoidal curve along the circumference of the protective shell 305.

[0032] The louver 306 is rotatably connected to the inner wall of the protective shell 305 via a pivot. A fixed shaft is fixedly connected to the inner side of the protective shell 305. A drive tube is rotatably connected to the surface of the fixed shaft. A push mechanism connected to the power module 7 is fixedly connected to the surface of the drive tube. A sealing cover is hinged to the top of the window frame. The end of the push mechanism away from the drive tube is fixedly connected to the surface of the sealing cover. The push mechanism includes a support arm fixedly connected to the surface of the drive tube. An auxiliary push arm is rotatably connected to the end of the support arm away from the drive tube via a pivot. The end of the auxiliary push arm away from the support arm is rotatably connected to the side of the sealing cover via a pivot.

[0033] The heat dissipation module 302 includes an infusion pipe 308 arranged axially along the mounting rod 2, a protective sleeve is provided axially on the outside of the infusion pipe 308, an atomizing nozzle 303 connected to the rainwater collection module 6 through the infusion pipe 308 is installed on one side of the protective sleeve, a heating module 307 connected to the power module 7 is provided on both sides of the protective sleeve, and a heat dissipation plate 304 is provided on the side of the heating module 307.

[0034] The rainwater collection module 6 includes a water collection umbrella 601, which is an inverted umbrella shape. A pole 602, which is fixedly connected to the mounting rod 2, is provided in the middle of the water collection umbrella 601. Multiple ropes, which are fixedly connected to the edge of the water collection umbrella 601, are provided around the pole 602. A water-absorbing sponge is provided on the surface formed by the ropes. A water storage tank 603, which is equipped with a filter module and connected to the infusion pipe 308, is provided at the bottom of the water collection umbrella 601. A mechanical level gauge is provided inside the water storage tank 603.

[0035] The protective shell 305 has an air inlet pipe 309 on its contraction section that connects the inside and outside of the protective shell 305. There is at least one air inlet pipe 309 and they are arranged in a ring at intervals around the axis of the protective shell 305. The angle between the air inlet pipe 309 and the axis of the protective shell 305 is 90 degrees to 135 degrees.

[0036] The bottom of the mounting rod 2 is provided with a temporary storage box 1 that is connected to the water storage tank 603. The temporary storage box 1 is a hollow barrel shape. A liquid level sensor is provided inside the temporary storage box 1. A water pump connected to the infusion pipe 308 is provided inside the temporary storage box 1.

[0037] The protective shell 305 also includes a left half shell and a right half shell connected at the end face. The area enclosed by the left half shell and the right half shell constitutes a temperature and humidity regulating cavity isolated from the outside world. The left half shell and the right half shell are detachably connected by a sealing hinge.

[0038] The power module 7 is threadedly connected to the solar panel and wind power generation module of the mounting rod 2.

[0039] In this embodiment, the base station antenna 4 is enclosed by the area formed by the left and right half shells that are detachably and fixedly connected by hinges through contact between the left and right end faces, thereby isolating the base station antenna 4 from the surrounding environment. In order to ensure that the signal is not blocked, the protective shell 305 is made of inorganic materials, such as plastic, rubber or plexiglass.

[0040] In order to enable the protective shell 305 to rotate, the base station antenna 4 is fixed on the mounting rod 2, and sealed bearings that cooperate with the protective shell 305 are installed at the upper and lower ends of the base station antenna 4, thereby isolating the base station antenna 4 from the external environment. The protective shell 305 can effectively protect the base station antenna 4, thereby reducing the interference of the outside world such as wind, frost, rain and snow due to seasonal weather changes, and ensuring the stability of signal transmission.

[0041] The base station antenna 4 generates heat during operation. If the excess heat cannot be dissipated into the atmosphere in time, the temperature of related equipment in the base station antenna 4 will rise, eventually damaging the base station antenna 4. Therefore, the diameter of the protective shell 305 gradually decreases downwards along the axial direction of the mounting rod 2, and rapidly narrows at the lower end where it meets the sealed bearing. When the protective shell 305 rotates, a pressure difference is generated between the inner and outer sides of the protective shell 305. To facilitate heat exchange with the outside environment, several spaced window frames are provided on the outer side of the protective shell 305. The window frame is equipped with louvers 306, and the protective shell 305 is provided with an air inlet pipe 309 that connects the inside and outside of the protective shell 305 on the rapidly narrowing section. There is at least one air inlet pipe 309, which is arranged in a ring around the axis of the protective shell 305 at intervals, and the angle between the air inlet pipe 309 and the axis of the protective shell 305 is 90 degrees to 135 degrees, preferably 120 degrees, to reduce the amount of rainwater entering the interior of the protective shell 305 through the air inlet pipe 309 when it rains.

[0042] To prevent rainwater from entering the protective housing 305 through the louvers 306 during rain, a fixed shaft is fixedly connected to the inner side of the protective housing 305. A drive tube is rotatably connected to the surface of the fixed shaft, and a push mechanism connected to the power module 7 is fixedly connected to the surface of the drive tube. A sealing cover is hinged to the top of the window frame. The end of the push mechanism away from the drive tube is fixedly connected to the surface of the sealing cover. The push mechanism includes a support arm fixedly connected to the surface of the drive tube. An auxiliary push arm is rotatably connected to the end of the support arm away from the drive tube via a rotating shaft, and the end of the auxiliary push arm away from the support arm is rotatably connected to the side of the sealing cover via a rotating shaft. The power module drives the push mechanism to rotate, which in turn drives the sealing cover to seal the window frame and prevent rainwater from entering. The sealing cover remains open when there is no rain in summer.

[0043] In order to enable the protective shell 305 to rotate under the action of wind, a fan blade module 5 is installed between the window frames of the protective shell 305. The fan blade module 5 includes a rotating shaft rotatably connected to the protective shell 305, and a fan blade 501 located at the top of the rotating shaft. The distance from the top of each fan blade 501 to the protective shell 305 is distributed in a sinusoidal curve along the axial direction of the mounting rod 2 and in a sinusoidal curve along the circumference of the protective shell 305. That is, the size of the fan blades 501 is different around the protective shell 305. When the wind blows over the protective shell 305, the resultant force on the protective shell 305 is not zero. The resultant force drives the protective shell 305 to rotate around the axis of the mounting rod 2. At the same time, each fan blade 501 is rotatably connected to the rotating shaft. When the wind blows over the fan blade 501, it will deflect, which increases the resultant force.

[0044] In summer, when the wind blows across the protective shell 305, it causes it to rotate. During the rotation, the pressure on the outer surface of the protective shell 305 is less than the pressure on the narrow section of the protective shell 305. Cold air from the outside enters the internal cavity of the protective shell 305 through the air inlet pipe 309 on the narrow section of the protective shell 305 and exchanges heat with the air inside. The heated air is then discharged through the louvers 306. When the pressure around the protective shell 305 is relatively chaotic, cold air from the outside may enter the internal cavity of the protective shell 305 through the louvers 306 and exchange heat with the air inside. Then, it is discharged from the protective shell 305 through the air inlet pipe 309 on the narrow section of the protective shell 305.

[0045] While the protective shell 305 rotates, it drives the cleaning brush 301 on its internal surface to clean the base station antenna 4. At the same time, in order to reduce the interference of external dust, filter modules are installed at the louvers 306 and the air inlet duct 309.

[0046] To enhance the cooling effect, a rainwater collection module 6 is installed at the top of the mounting rod 2. This module includes a water-collecting umbrella 601, which is inverted. An umbrella rod 602, fixed to the mounting rod 2, is located in the middle of the umbrella 601. Multiple ropes, fixed to the edges of the umbrella 601, are arranged around the umbrella rod 602. A water-absorbing sponge is provided on the surface formed by the ropes. At the bottom of the umbrella 601, a water storage tank 603, equipped with a filter module and connected to an infusion pipe 308, is installed. A mechanical level gauge is installed inside the water storage tank 603. To complement the rainwater collection module 6, a temporary storage box 1 is installed at the lower end of the mounting rod 2. The water storage tank 603 is connected to the temporary storage box 1, which is a hollow barrel. A level sensor and a water pump connected to the infusion pipe 308 are installed inside the temporary storage box 1. The temporary storage box 1 can also be replenished with water from the outside.

[0047] When it rains, rainwater is collected and stored through the rainwater collection module 6. When it is necessary to enhance cooling, water in the water storage tank 603 or the temporary storage tank 1 is atomized through the infusion tube 308 and sprayed into the cavity enclosed by the protective shell 305 through the atomizing nozzle 303 installed on the heat dissipation module 302. The water droplets absorb heat and turn into water vapor, which is discharged with the outside air, thereby accelerating the cooling speed.

[0048] In winter, the protective shell 305 can be stopped from rotating by the brake, and then the inner cavity of the protective shell 305 can be heated by the heating module 307 to ensure that the base station antenna works within the normal operating temperature range and consumes less energy. In order to coordinate the work of each module, a microcontroller is installed in the protective shell to connect the atomizing nozzle 303 of the heat dissipation and cleaning module 3, the heating module 307, the power module 7, the water pump and the brake and other functional modules.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
