[0002] Communication base stations are the core equipment of mobile communication networks, responsible for transmitting and receiving wireless signals, ensuring stable communication connections for mobile devices such as smartphones while they are in motion. The supporting systems for communication base stations include towers, equipment rooms, power supplies, air conditioning, and other equipment, providing support for various systems within the communication base station.

[0003] Some communication base stations (such as macro base stations) are generally located in areas with higher terrain (such as mountain tops or highlands) to improve signal coverage by utilizing the terrain; they are avoided in low-lying areas, canyons, or areas blocked by tall buildings to prevent signal attenuation caused by reflection and diffraction.

[0004] To ensure the long-term normal operation of electrical equipment within the power cabinet, current technology typically uses air conditioning to regulate the temperature. However, due to... In some regions, temperatures vary greatly depending on the season or time of day. The locations of communication base stations (such as macro base stations) within the power supply cabinets are also relatively remote, resulting in higher power transmission costs. The long-term use of air conditioning for temperature regulation significantly increases the operating costs of communication base stations.

Detailed Implementation

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0022] Example like Figures 1 to 6As shown in the figure, this embodiment designs a power cabinet structure for a communication base station, including a power cabinet 2, a lifting mechanism 6, a PLC controller, and other structures.

[0023] The power cabinet 2 is a vertical, elongated cabinet, comprising an inner cabinet 22 and an outer shell 21. The inner cabinet 22 is a sealed structure, housing various electrical equipment and is isolated from the natural environment to prevent dust and other debris from entering and affecting the safe operation of the electrical equipment. The outer shell 21 is located outside the inner cabinet 22, providing protection for it. A side ventilation channel 23 is formed between the outer shell 21 and the inner cabinet 22. When airflow passes through the side ventilation channel 23, it cools the inner cabinet 22, ensuring the stability of the electrical equipment's operation.

[0024] The power supply cabinet 2 is installed at the mounting port on the top of the base station equipment room 1 of the communication base station during use. The upper part of the power supply cabinet 2 is located outside the base station equipment room 1, and the lower part of the power supply cabinet 2 is located inside the base station equipment room 1. Several ventilation holes can be provided on the outer cabinet shell 21, so that natural air can come into contact with the surface of the inner cabinet 22 through the ventilation holes, thereby cooling the inner cabinet 22. A rotatable perforated plate can be provided on the inner side of the ventilation hole, and the upper part of the perforated plate is rotatably connected to the upper hole of the ventilation hole, so that natural air can enter the outer cabinet shell 21 through the ventilation hole, while the airflow inside the outer cabinet shell 21 is difficult to exhaust through the ventilation hole.

[0025] The lifting mechanism 6 is installed on the inner top of the base station equipment room 1. The lifting mechanism 6 includes an internal threaded sleeve 62, a lead screw 65, a transmission chain 66, and a lifting motor 61. The four internal threaded sleeves 62 are respectively located at the four corners of the bottom of the power cabinet 2. The four lead screws 65 are threadedly engaged with the four internal threaded sleeves 62. The top of the four lead screws 65 is connected to the driven sprockets 67. The driving sprocket 69 on the output shaft of the lifting motor 61 is connected to the driven sprockets 67 through the transmission chain 66. When the lifting motor 61 is energized and rotates forward or reverse, the driving sprocket 69 also rotates synchronously, and drives the four driven sprockets 67 to rotate through the transmission chain 66, which in turn causes the lead screw 65 to rotate, thereby controlling the internal threaded sleeves 62 to move up and down along the lead screw 65, thus realizing the lifting control of the power cabinet 2.

[0026] The lifting mechanism 6 also includes a top mounting base 610, with a bottom ring frame 63 located below it, and the two are fixed together by an L-shaped frame 64; the upper and lower ends of the lead screw 65 are rotatably connected to the top mounting base 610 and the bottom ring frame 63, respectively. The bottom ring frame 63 and the L-shaped frame 64 effectively improve the stability of the power cabinet 2 during lifting.

[0027] The PLC controller is installed in the base station equipment room 1. Temperature sensors are installed both indoors and outdoors, and the PLC controller is connected to these sensors to collect indoor and outdoor temperature data. Additionally, the PLC controller is connected to the lifting motor 61 to control the lifting position of the power cabinet 2. The PLC controller can adjust the ratio of the indoor to outdoor portion of the power cabinet 2 based on the temperature difference. When the temperature difference exceeds a threshold, the lifting mechanism 61 can control the power cabinet 2 to rise or fall, increasing the outdoor portion or increasing the indoor portion, thereby changing the volume of the outdoor portion and achieving different cooling effects from natural wind.

[0028] Flat internal heat exchange tubes 27 are embedded in the inner wall of the inner cabinet 22. The internal heat exchange tubes 27 are S-shaped, with one end of the tube in the width direction located inside the inner cabinet 22 and the other end located outside the inner cabinet 22. A circulating heat exchange medium is contained within the internal heat exchange tubes 27, enabling heat exchange circulation. Furthermore, both the inner and outer sides of the inner cabinet 22 can undergo rapid heat exchange via the internal heat exchange tubes 27.

[0029] The upper and lower sides of the inner heat exchange tube 27 are respectively abutted against the cabinet wall of the inner cabinet 22 by anti-slip strips 210. The anti-slip strips 210 are made of rubber or plastic materials, which not only increases the connection between the inner heat exchange tube 27 and the inner cabinet 22, but also increases the sealing of the inner cabinet 22 to prevent dust or debris from entering the inner cabinet 22.

[0030] The outer top of the outer casing 21 is equipped with a rotatable non-powered vent 26. The central shaft of the non-powered vent 26 is connected to the second circulation pump body 29 via a reducer 28. The second circulation pump body 29 is connected to the inner heat exchange tube 27 and accelerates the flow of water medium within the inner heat exchange tube 27. The non-powered vent 26 has a rotatable structure and can rotate under the influence of indoor and outdoor temperature differences and natural wind in the base station equipment room 1, thereby driving the second circulation pump body 29 to rotate and promoting the circulation of the medium in the inner heat exchange tube 27.

[0031] The base station equipment room 1 is equipped with a base station heat exchange pipe 5, which is connected to the inner heat exchange pipe 27 via a flexible hose. When the power cabinet 2 is raised or lowered, the flexible hose can adapt to its height change, thereby reducing the constraint on the raising and lowering of the power cabinet 2. A first circulation pump 8 is installed on the pipe between the inner heat exchange pipe 27 and the base station heat exchange pipe 5. The first circulation pump 8 is driven by a motor. When the motor is energized, the first circulation pump 8 can drive the medium to circulate between the inner heat exchange pipe 27 and the base station heat exchange pipe 5. A one-way valve can be connected in series on the flexible hose to prevent the medium from flowing back into the base station heat exchange pipe 5 when the second circulation pump 29 circulates the medium.

[0032] The outer cabinet 21 has a lower cavity 25 at the bottom and an upper cavity 24 at the top; the second circulation pump is installed in the upper cavity 24; both the lower cavity 25 and the upper cavity 24 are located outside the inner cabinet 22, and the cables leading out from the inner cabinet 22 are routed through the lower cavity 25 and the upper cavity 24.

[0033] A ventilation window 12 is provided on the side wall of the base station equipment room 1, and a ventilation fan 7 is provided inside the ventilation window 12. When the ventilation fan 7 is powered on, it can ventilate the base station equipment room 1.

[0034] A wind deflector 10 is provided between the side wall of the outer cabinet 21 and the base station equipment room 1; the wind deflector 10 is used to block air from passing through the gap between the outer cabinet 21 and the base station equipment room 1, thereby preventing the airflow caused by the temperature difference between indoor and outdoor from passing through the gap and affecting the effect.

[0035] A canopy is installed above the base station equipment room 1, and cable hangers 3 are installed on the inner top of the canopy and in the base station equipment room 1. The cables leading out from the bottom of the power cabinet 2 are hung on the cable hangers 3 in the base station equipment room 1, and some cables hang freely. The cables leading out from the top of the power cabinet 2 are hung on the cable hangers 3 on the canopy after passing around the rotating arm 4. The rotating arm 4 is rotatably connected to the canopy, and the middle part of the rotating arm 4 is connected to the canopy through a spring. When the power cabinet 2 moves up and down, the rotating arm 4 can rotate adaptively, thereby avoiding pulling on the cables and affecting the safety of the electrical room equipment operation.

[0036] The power cabinet structure of the communication base station in this embodiment has the following cooling and temperature regulation methods during use: Method 1: The lifting mechanism 6 is used to control the lifting of the power cabinet 2, so that the power cabinet 2 is partially extended outside the base station equipment room 1, completely extended outside the equipment room, or completely placed inside the equipment room, so as to change the cooling effect of the outdoor natural wind on the power cabinet 2.

[0037] Method 2: Through the flat internal heat exchange tube 27, the inner and outer sides of the inner cabinet 22 can be cooled and regulated by the medium.

[0038] Method 3: The airflow created by the temperature difference between indoors and outdoors, or the natural wind from outdoors, drives the non-powered vent 26 to rotate, thereby causing the second circulation pump body 29 to control the medium to circulate between the upper and lower parts of the inner heat exchange tube 27, thus accelerating the circulation between the indoor and outdoor parts of the power cabinet 2 and improving the cooling and temperature regulation effect. In addition, when the natural wind drives the non-powered vent 26 to rotate, the non-powered vent 26 can introduce outdoor air into the side ventilation channel 23 to achieve air cooling.

[0039] Method 4: The second circulation pump 29 operates, causing the medium to flow between the base station heat exchange tube 5 and the inner heat exchange tube 27, thereby realizing heat exchange between the two and thus achieving cooling and temperature regulation of the power cabinet 2.

[0040] Methods 1, 2, and 3 all have extremely low power consumption and are suitable for scenarios such as mountaintop communication base stations. Method 4 also adopts a low-cost heat exchange method, which consumes less electricity compared to turning on the air conditioner.

[0041] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
