Description

Technical Field

[0001] The present invention belongs to the technical field of base station power supplies, and particularly relates to a micro power module for a communication base station. Background Art

[0002] A base station, namely a public mobile communication base station, is a form of radio station. It refers to a radio transceiver station that transmits and receives information between a mobile communication switching center and a mobile phone terminal within a certain radio coverage area. The operation of each component structure of the base station requires power supply and distribution by the base station power supply. The existing communication base station power supplies usually use a method of first parallel connection, then series connection, and then encapsulation to form the battery pack inside the base station power supply.

[0003] In the prior art, the communication base station power supply usually integrates a plurality of batteries into a power supply housing, and dissipates heat from the entire base station power supply by sending air into the power supply housing. During the operation of the base station power supply, heat dissipation control is achieved by monitoring the temperature inside the power supply housing. When a battery inside the base station power supply catches fire due to a short circuit or other faults, only when the staff discovers and conducts external fire extinguishing treatment can it be dealt with. It is impossible to achieve precise fire extinguishing inside the base station power supply, thereby reducing the fire extinguishing effect of the base station power supply. For this reason, we provide a micro power module for a communication base station to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] For specific embodiment 1, please refer to Figure 1-17, the present invention is a micro power module for a communication base station, which includes a power shell 1, and multiple groups of battery modules 2 are installed inside the power shell 1 (divided into upper, middle and lower groups); a conduction control component 3 corresponding to each battery module 2 is installed on the power shell 1; among them, the battery module 2 includes a battery installation component 4, a conductive mechanism 5 and a powder fire extinguishing component 9; the battery installation component 4 includes a battery installation cylinder 401, and a number of battery bodies 13 connected in series are installed inside the battery installation cylinder 401; the conductive mechanism 5 includes a conductive component 6 and a first conductive part 7, the conductive component 6 includes a fixed support part, and a second conductive part 8 is rotatably installed on one side of the support part, and the battery installation cylinder 401 is fixedly installed between the first conductive part 7 and the second conductive part 8 to ensure synchronous rotation among the first conductive part 7, the second conductive part 8 and the battery installation cylinder 401, and the series connection of each battery body 13 inside the battery installation cylinder 401 is realized through the first conductive part 7 and the second conductive part 8.

[0037] The powder fire extinguishing component 9 is arranged inside the battery installation cylinder 401 and is coaxial with it. The powder fire extinguishing component 9 is composed of an outer storage part and an inner storage part. The outer storage part is fixedly connected to and communicates with the support part, that is, the rotation of the outer storage part is prevented through the support part. The inner storage part is in clearance fit inside the outer storage part and penetrates the first conductive part 7 (the inner storage part can rotate); the outer storage part includes a diversion cavity and a storage cavity. The diversion cavity is used to connect the inner cavity of the battery installation cylinder 401 and the support part, that is, the air flow can be transported into the inner cavity of the battery installation cylinder 401 through the support part and the diversion cavity for air cooling of each battery body 13 installed in the battery installation cylinder 401. The outer storage part is provided with an outer powder spraying hole 901 communicating with the storage cavity, and the inner storage part is provided with inner powder spraying holes 902 corresponding to and offset from the outer powder spraying hole 901 one by one. The dry powder for fire extinguishing is stored between the outer storage part and the inner storage part (the dry powder is in solid powder form).

[0038] The conduction control component 3 includes a first air guide cavity 301 and a second air guide cavity 302. A transmission component meshing with the inner storage part is arranged inside the first air guide cavity 301. The first air guide cavity 301 is communicated with the second air guide cavity 302 through an air guide port 303, and the second air guide cavity 302 is communicated with the inner storage part; a first air duct and a second air duct are respectively installed on the power shell 1. The first air duct is used to transport the air flow into each support part, and then enter the inner cavity of the battery installation cylinder 401 through each support part and the diversion cavity for heat dissipation of the battery body 13. The second air duct is used to transport the air flow into each first air guide cavity 301, and the continuously entering air flow in the first air guide cavity 301 pushes the transmission component to move and drives the inner storage part to rotate.

[0039] In some embodiments, such as Figure 4 and Figure 5As shown, the power supply housing 1 includes a first side plate 101 and a second side plate 102 which are oppositely arranged. Installation openings 103 are provided on both the first side plate 101 and the second side plate 102. The first air duct includes an air inlet docking pipe 104. The end of the air inlet docking pipe 104 is connected to a U-shaped air guide pipe 105 installed on the first side plate 101. A first air guide pipe 106 is connected to the U-shaped air guide pipe 105. The end of the first air guide pipe 106 is connected to a second air guide pipe 107 installed on the second side plate 102. The second air duct includes a third air guide pipe 108 connected to the air inlet docking pipe 104. The end of the third air guide pipe 108 is connected to a fourth air guide pipe 109. Control valves 110 (which can be set as electric valves, such as solenoid valves, and each control valve 110 is externally powered) are installed on both the air inlet docking pipe 104 and the third air guide pipe 108. When the control valve 110 on the air inlet docking pipe 104 is opened and the control valve 110 on the third air guide pipe 108 is closed, the first air duct is in an open state at this time. The external air supply device transports the air flow into the air inlet docking pipe 104, and then it is transported to the inside of the upper and lower support parts by the U-shaped air guide pipe 105. At the same time, the air flow in the U-shaped air guide pipe 105 enters the inside of the middle support part along the first air guide pipe 106 and the second air guide pipe 107. In this way, the air flow can be continuously transported into the inner cavities of the battery installation cylinders 401. The air flow entering the inner cavities of the battery installation cylinders 401 is used for air-cooling the battery bodies 13. When the control valve 110 on the air inlet docking pipe 104 is closed and the control valve 110 on the third air guide pipe 108 is opened, the second air duct is in an open state at this time. The external air supply device transports the air flow into the air inlet docking pipe 104, and then it is continuously transported to the first air guide cavity 301 by the third air guide pipe 108 and the fourth air guide pipe 109.

[0040] In some embodiments, such as Figure 6 and Figure 7As shown, the conduction control component 3 further includes a conduction control box 304 installed in the corresponding installation port 103. A partition plate 305 is fixed inside the conduction control box 304. The first air guide cavity 301 and the second air guide cavity 302 are respectively located on both sides of the partition plate 305. A ventilation pipe 306 is tightly inserted into one side of the conduction control box 304 (that is, the ventilation pipe 306 can be detached from the insertion port on the conduction control box 304). The transmission component includes a piston plate 307 slidably arranged in the first air guide cavity 301. A meshing part 308 is fixed on one side of the piston plate 307. An elastic element 309 connected to the meshing part 308 is arranged inside the first air guide cavity 301. The ventilation pipe 306 and the fourth air duct 109 are tightly inserted and matched with each other (that is, the ventilation pipe 306 can also be detached from the fourth air duct 109). In the initial state, the piston plate 307 abuts against the inner wall of the conduction control box 304 under the elastic force of the elastic element 309. At this time, the ventilation pipe 306 is blocked by the piston plate 307. The air flow continuously conveyed to each ventilation pipe 306 through the second air duct enters into each first air guide cavity 301. The piston plate 307 is driven to move away from the ventilation pipe 306 by the wind pressure. The meshing part 308 that moves synchronously with the piston plate 307 gradually compresses the elastic element 309 until the meshing part 308 abuts against the inner wall of the conduction control box 304. At this time, the piston plate 307 moves to the right side of the air guide port 303. The air flow entering the first air guide cavity 301 from the ventilation pipe 306 enters into the second air guide cavity 302 along the air guide port 303. The air flow entering the second air guide cavity 302 enters into the storage cavity of the outer storage part through the inner storage part, and the outer powder spraying holes 901 are aligned with the corresponding inner powder spraying holes 902.

[0041] In some embodiments, such as Figure 12 and Figure 13As shown, a plurality of battery support tubes 402 are circumferentially arranged on the inner wall of the battery installation cylinder 401. A number of strip-shaped heat dissipation holes 403 are formed on the circumferential side surface of the battery support tube 402. Axial through ports 404 corresponding to the battery support tubes 402 one by one are formed on the circumferential side surface of the battery installation cylinder 401. A fixed number of battery bodies 13 can be serially installed into the battery support tubes 402 through the axial through ports 404. The battery support tubes 402 are communicated with the corresponding axial through ports 404. A number of battery bodies 13 are serially installed inside the battery support tubes 402. The air flow entering the inner cavity of the battery installation cylinder 401 enters the inside of the battery support tubes 402 along each strip-shaped heat dissipation hole 403, and then flows out to the outside of the battery installation cylinder 401 through each axial through port 404. In this way, the contact air-cooling heat dissipation of each battery body 13 can be realized. By directly flowing the air flow through the surface of the battery body 13, compared with the heat dissipation method of directly flowing the air flow through the inner cavity of the power supply case 1, the heat dissipation method in this embodiment can achieve precise heat dissipation of each battery body 13, which is beneficial to improving the heat dissipation effect of the entire base station power supply; The support part includes a first support tube 501. A support disc 502 is fixed at the end of the first support tube 501. A first magnetic disc 503 is fixedly installed on the circumferential side surface of the first support tube 501. The U-shaped air duct 105 and the second air duct 107 are respectively tightly inserted into the corresponding first support tubes 501. In this way, the air flow can be transported into each first support tube 501 through the first air duct.

A second support tube 505 is communicated and arranged on one side of the first support cover 504. The second conductive part 8 includes a second support cover 506 rotatably arranged on the support disc 502. The first support cover 504 and the second support cover 506 are respectively sleeved and installed at both ends of the battery installation cylinder 401 (connected by fasteners); a positive electrode conductive member 507, a negative electrode conductive member 508 and an arc-shaped conductive member 509 are arranged inside both the first support cover 504 and the second support cover 506. The arc-shaped conductive member 509 is connected to the positive electrode conductive member 507 and the negative electrode conductive member 508 on both sides thereof. A first wiring part electrically connected to the corresponding negative electrode conductive member 508 is installed on one side of the first support cover 504 (this first wiring part is arranged at position A and is connected to the corresponding negative electrode conductive member 508). A second wiring part 510 electrically connected to the corresponding positive electrode conductive member 507 is installed on the circumferential side of the second support cover 506 (this second wiring part 510 is arranged at position B and is connected to the corresponding positive electrode conductive member 507). That is, the negative electrode conductive member 508 on the first support cover 504 is electrically connected to the negative electrode of the corresponding battery body 13, the positive electrode conductive member 507 on the first support cover 504 is electrically connected to the positive electrode of the corresponding battery body 13, the negative electrode conductive member 508 on the second support cover 506 is electrically connected to the negative electrode of the corresponding battery body 13, the positive electrode conductive member 507 on the second support cover 506 is electrically connected to the positive electrode of the corresponding battery body 13.

The second wiring part 510 on the middle-layer battery module 2 is connected to the first wiring part on the upper-layer battery module 2 through a wire. The first wiring part on the lower-layer battery module 2 and the second wiring part 510 on the upper-layer battery module 2 are electrically connected to the power interface, and power supply to external devices is realized through the power interface.

[0043] When the assembly of the base station power supply is completed and put into use, the internal temperature of the base station power supply is monitored in real time by the temperature sensor inside the power supply housing 1. The external air supply device, the temperature sensor, and the control valves 110 on the air inlet docking pipe 104 and the third air duct 108 are all controlled by the control system. The opening and closing times of the external air supply device and the control valve 110 on the air inlet docking pipe 104 are set in the control system. Every certain period of time, the control system starts the external air supply device and opens the control valve 110 on the air inlet docking pipe 104, and conveys the air flow to the inside of each first support pipe 501 through the first air duct. The air flow entering the first support pipe 501 enters the outer material storage part, and then enters the inside of the battery installation cylinder 401 through the diversion cavity on the outer material storage part. The air flow entering the battery installation cylinder 401 realizes the air-cooling of each battery body 13. The air flow passing through each battery installation cylinder 401 enters the inner cavity of the power supply housing 1 and is then discharged through the exhaust grille on the power supply housing 1, thereby realizing the heat dissipation of the entire base station power supply. After reaching the heat dissipation time set by the control system, the control system controls to close the external air supply device and the control valve 110 on the air inlet docking pipe 104, or the temperature threshold for heat dissipation is set by the control system. When it is monitored that the internal temperature of the power supply housing 1 is approaching the set threshold, the control system controls to start the external air supply device and open the control valve 110 on the air inlet docking pipe 104, and realizes the air-cooling of the battery body 13 through the first air duct.

The fixed pipe 906 is fixedly installed inside the first support pipe 501 (thereby ensuring that the outer material storage cylinder 903 cannot rotate). The outer powder spraying holes 901 are formed on the circumferential side of the outer material storage cylinder 903. The air flow entering the inside of each first support pipe 501 enters the inside of the battery installation cylinder 401 through the fixed pipe 906 and the air outlet 905. The air flow entering the inside of the battery installation cylinder 401 is used to realize the air-cooling of each battery body 13.

[0045] The inner material storage part includes an inner material storage cylinder 907 which is in clearance fit inside the outer material storage cylinder 903 (that is, the outer wall of the inner material storage cylinder 907 is attached to the inner wall of the outer material storage cylinder 903). Inner powder spraying holes 902 are opened on the circumferential side of the inner material storage cylinder 907. A fire extinguishing gas delivery pipe 908 which is communicated with the inner material storage cylinder 907 is fixed at the end of the inner material storage cylinder 907. A gear 909 is installed on the circumferential side of the fire extinguishing gas delivery pipe 908. The fire extinguishing gas delivery pipe 908 is in through fit inside the second support pipe 505. The fire extinguishing gas delivery pipe 908 is rotationally connected with the conduction control box 304 and communicated with the second air guiding cavity 302. The gear 909 is located inside the first air guiding cavity 301 and meshes with the meshing part 308.

[0046] Set a high temperature threshold value (this high temperature threshold value is the temperature when the battery catches fire) in the control system. When the temperature sensor monitors this high temperature threshold value, the control system controls to start the external air supply device and open the control valve 110 on the third air guiding pipe 108. At this time, the second air duct is in an open state. The air flow is continuously delivered into each air delivery pipe 306 through the second air duct, and then is delivered to the first air guiding cavity 301 by the air delivery pipe 306. The piston plate 307 is driven to move away from the air delivery pipe 306 by the wind pressure. The meshing part 308 that moves synchronously with the piston plate 307 gradually compresses the elastic element 309 until the meshing part 308 abuts against the inner wall of the conduction control box 304 (in this process, the gear 909 is driven to rotate a certain angle by the meshing part 308, that is, the inner material storage cylinder 907 rotates a certain angle. At this time, the inner powder spraying holes 902 are aligned with the corresponding outer powder spraying holes 901). At this time, the piston plate 307 moves to the right side of the air guiding port 303. The air flow entering the first air guiding cavity 301 from the air delivery pipe 306 enters the second air guiding cavity 302 along the air guiding port 303. The air flow entering the second air guiding cavity 302 enters the inner material storage cylinder 907 through the fire extinguishing gas delivery pipe 908, and then is discharged to the inner side of the battery installation cylinder 401 through the inner powder spraying holes 902 and the outer powder spraying holes 901. In this process, the fire extinguishing dry powder in the storage cavity on the outer material storage cylinder 903 is blown out by the air flow and covered on the surface of the battery body 13. In this way, the fire extinguishing treatment of the base station power supply can be realized or the fire can be reduced, so as to facilitate the staff to make an emergency fire extinguishing response.

[0047] In some embodiments, such as Figure 9 and Figure 10As shown, the battery module 2 further includes a battery positioning assembly 10. Among them, the battery positioning assembly 10 includes a carrier 1001, on which a positioning cylinder 1002 is fixedly installed.

A positioning cavity 1006 communicating with the arc-shaped air guide cavity 1005 is provided on the inner wall of the positioning cylinder 1002, and an elastic positioning member 1007 (made of high-temperature resistant and fireproof material) is installed inside the positioning cavity 1006. When a certain amount of air is conveyed into the positioning cavity 1006 to cause the elastic positioning members 1007 to gradually expand, the expanded elastic positioning members 1007 are closely attached to the battery body 13 at the corresponding positions, thereby enabling the installation and positioning of each battery body 13. An air guide pipe group 1008 communicating with each arc-shaped air guide cavity 1005 is installed on the carrier 1001, and a horizontal connecting pipe 1009 is installed on the air guide pipe group 1008.

A conveying pipe 1103 tightly inserted into the horizontal connecting pipe 1009 is installed on the circumferential side of the support ring 1101 (the conveying pipe 1103 can be tightly inserted into the horizontal connecting pipe 1009 under the action of magnetic attraction). A control valve 110 (this control valve 110 is a manually operated on-off valve) is installed on the conveying pipe 1103. When the control valve 110 on the conveying pipe 1103 is opened, a certain amount of air is conveyed into each arc-shaped air guide cavity 1005 through the conveying pipe 1103, the horizontal connecting pipe 1009, and the air guide pipe group 1008, causing the elastic positioning members 1007 to expand and closely adhere to the battery body 13 to achieve positioning. Subsequently, when the control valve 110 on the conveying pipe 1103 is closed, the installation and positioning of each battery body 13 on the battery module 2 are completed. Two support frames 1010 (connected by fasteners) are symmetrically installed on the top of the carrier 1001. The first support pipe 501 is fixedly installed on the corresponding support frame 1010, and the second support pipe 505 is closely and rotatably connected to the corresponding support frame 1010 (that is, when no external force acts on the second support pipe 505, the first conductive part 7 does not rotate).

[0049] In some embodiments, as Figure 2 、 Figure 3 and Figure 8As shown, a module mounting rack 12 is provided inside the power supply housing 1. The module mounting rack 12 includes a module mounting base 1201. The carrier rack 1001 is inserted and fitted between the module mounting bases 1201. The entire module mounting rack 12 is a detachable assembled structure, and the installation and support of each battery module 2 are realized through the module mounting base 1201.

[0050] Place a certain amount of fire extinguishing dry powder in the storage cavity on the external storage cylinder 903 or in the internal storage cylinder 907. Then, install the battery installation assembly 4 inside the positioning protection cylinder 1002 and make the battery insertion port 1003 face upward. Support the battery installation assembly 4 through the positioning protection cylinder 1002. Next, insert the external storage cylinder 903 into the battery installation cylinder 401, and place the support frame 1010 at the position of the external storage cylinder 903 on the top of the carrier rack 1001. Sleeve and install the second support cover 506 at one end of the battery installation cylinder 401, and realize the fixed connection between the second support cover 506 and the battery installation cylinder 401 through fasteners. Realize the fixed connection between the support frame 1010 and the carrier rack 1001 through fasteners. At this time, the second support cover 506 is in contact with the end of the positioning protection cylinder 1002. Subsequently, insert the internal storage cylinder 907 into the external storage cylinder 903 (keep the internal storage cylinder 907 from rotating by the elastic force of the elastic element 309), and place the support frame 1010 at the position of the internal storage cylinder 907 on the top of the carrier rack 1001. Sleeve and install the first support cover 504 at the other end of the battery installation cylinder 401, and realize the fixed connection between the first support cover 504 and the battery installation cylinder 401 through fasteners. Realize the fixed connection between the support frame 1010 and the carrier rack 1001 through fasteners. Thus, the assembly of one battery module 2 is completed. Subsequently, insert the battery body 13 downward from the position of the battery insertion port 1003 and install it into the upper battery support tube 402 for series connection. Drive the battery installation cylinder 401 to rotate a certain angle by rotating the first conductive part 7 and the second conductive part 8, so that the next battery support tube 402 rotates and aligns with the battery insertion port 1003, and install the same number of battery bodies 13 in series into the battery support tube 402. In this way, the series connection of each battery body 13 inside the battery module 2 is realized. Subsequently, the battery is fixed by the expanded elastic positioning member 1007 closely attached to the battery body 13.

[0051] After completing the series installation of the battery bodies 13 inside each battery module 2, each battery module 2 is installed and supported inside the module mounting frame 12. Then, the module mounting frame 12 carrying the battery module 2 is installed inside the power supply housing 1. After completing the installation of the first side plate 101 and the second side plate 102, the conduction control box 304 is tightly inserted into the corresponding installation opening 103. The ventilation pipe 306 is installed between the conduction control box 304 and the fourth air duct 109. At this time, the U-shaped air duct 105 and the second air duct 107 are respectively tightly inserted into the corresponding first support pipe 501, and the first air duct 106 and the second air duct 107 are connected (flange connection). Thus, the assembly of the entire base station power supply is completed.
