Detailed Description
The embodiment of the application provides outdoor communication power equipment which is used for supplying power to a communication device. The outdoor communication power supply device can be hung and installed on a carrier, so that a factory building is not required to be established, and a station is not required to be selected. In addition, the outdoor communication power supply equipment can realize self-sealing so as to meet the requirement of an outdoor power supply environment.
In this embodiment, the communication device is a base station. The base station is also called public mobile communication base station, and is a form of radio station, and refers to a radio transceiver station for transmitting information with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. It will be appreciated that in other embodiments, the communication device may be other types of communication equipment, such as a wireless lightning arrester, a server, etc., without limitation.
In order that those skilled in the art will better understand the present application, embodiments of the present application will be described with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an installation of an outdoor communication power supply device according to an embodiment of the application. As shown in fig. 1, the outdoor communication power supply apparatus 100 may be suspended from a carrier 200 for powering communication devices (not shown). Wherein the carrier 200 includes, but is not limited to, the communication device itself, a wall, a pole, etc., supporting carrier. In the embodiment of the present application, the outdoor communication power supply apparatus 100 is suspended from a communication base station and is used to supply power to the communication base station.
Specifically, the outdoor communication power supply apparatus 100 may be mounted on the carrier 200 by a mounting structure 300. The mounting structure 300 may be integrated with the outdoor communication power supply apparatus 100 or may be separate from the outdoor communication power supply apparatus 100, so long as the outdoor communication power supply apparatus 100 can be fixedly mounted on the carrier 200, and is not limited herein.
As a specific implementation, the outdoor communication power supply apparatus 100 includes a base 10 and at least one power supply module 20 detachably mounted on the base 10. The mounting structure 300 is fixed to the base 10 and fixedly mounts the base 10 to the carrier 200.
Referring to fig. 2 in combination, fig. 2 is a functional block diagram of a base according to an embodiment of the application. The base 10 comprises an input busbar, an output busbar and at least one connection 11. The at least one connection 11 is electrically connected between the input bus bar and the output bus bar. Wherein the input bus is for receiving power from an external power source. Each connection 11 is used for mounting one power supply module 20. The output bus is for connection with at least one load 400 to power the at least one load 400. The load 400 is a component of the communication device that needs to be powered.
When at least one power supply module 20 is mounted on the base 10 through the at least one connection portion 11, the at least one power supply module 20 is electrically connected with the output bus bar and supplies power to the at least one load 400 through the output bus bar. In addition, when the power supply module 20 is mounted on the connection part 11, the base 10 and the power supply module 20 are connected in a sealing manner, so as to ensure that the outdoor communication power supply device 100 meets the requirement of an outdoor power supply environment.
It should be noted that the input bus and the output bus may also perform signal transmission with the connected device. For example, the input bus may be in signal communication with an external power source to which it is connected, and the output bus may be in signal communication with a load.
In the embodiment of the present application, since the outdoor communication power supply apparatus 100 can be suspended and mounted on a carrier 200, it is unnecessary to build a factory building and to select a site. In addition, when the at least one power supply module 20 is mounted on the base 10, the at least one power supply module 20 is in sealing connection with the base 10, so that the outdoor communication power supply device 100 can also realize self-sealing to meet the requirement of an outdoor power supply environment.
In addition, the base 10 includes a lightning protection module 12. In this embodiment, the base 10 includes two lightning protection modules 12, and one lightning protection module 12 is disposed on the input bus, and the other lightning protection module 12 is disposed on the output bus. This can prevent the outdoor communication power supply apparatus 100 from being affected and damaged by weather such as lightning.
In addition, in a specific implementation, the number of the at least one connection portion 11 is more than two, so that at least two power supply modules 20 can be connected in parallel, and since the more than two connection portions 11 are connected in parallel between the input bus and the output bus, the installation and maintenance of a single module do not affect the operation of other modules, so that the outdoor communication power supply device 100 can also supply power uninterruptedly during maintenance.
Referring to fig. 3, fig. 3 is a functional block diagram of an outdoor communication power supply device according to an embodiment of the application. As shown in fig. 3, the at least one power supply module 20 includes at least one of a rectifying module, a high voltage direct current output module (HVDC module), a battery module, a photovoltaic module, a DC/DC module, and a power distribution module.
Specifically, the rectification module is used for converting alternating current into direct current. The HVDC module is used for outputting high voltage (e.g. 380V) direct current. The battery module is used for storing energy and providing corresponding direct-current electric energy. The photovoltaic module is used for converting light energy into electric energy. The DC/DC module is used for converting the first direct current voltage into the second direct current voltage. The second dc voltage may be greater than the first dc voltage or less than the first dc voltage, specifically according to the actual requirement. The power distribution module is used for dividing the existing voltage into a plurality of paths and outputting the paths. The voltages of the respective paths may be the same or different according to specific load requirements.
In one embodiment, in order to simultaneously plug as many power supply modules 20 as possible to ensure a power supply output, the number of the connection portions 11 should be greater than or equal to the number of the power supply modules 20.
In addition, in one embodiment, any two connection portions 11 are electrically connected to each other. Thus, when the input bus is not connected to the power supply, one of the power supply modules 20 can also supply power to the load 400 through the other power supply module 20 so as to meet the power supply requirements of different loads 400, for example, the battery module can also supply power to other loads 400 after converting the voltage through the DC/DC module while supplying power to one load 400, and the power supply modules and the connection part can be mixed and inserted at will without limitation.
Referring to fig. 4, fig. 4 is a functional block diagram of an outdoor communication power supply device according to another embodiment of the present application. In this embodiment, the base 10 further includes a monitoring module 13. The monitoring module 13 is electrically connected to the at least one connection portion 11, and is used for monitoring whether the power supply module 20 is mounted on each connection portion 11, that is, for monitoring whether the power supply module 20 is electrically connected to the connection portion 11. When it is monitored that the power supply module 20 is mounted on a certain connection portion 11, the voltage and current of the power supply module 20 can be detected, and whether the power supply module 20 fails or not can be determined, so that the reliability of power supply is improved.
Specifically, a monitoring pin may be provided at each connection portion 11 for monitoring whether or not the power supply module 20 is mounted in the connection portion 11. For example, when the power supply module 20 is mounted on the connection part 11, the monitor pin outputs a low level, and when the power supply module 20 is inserted into the connection part 11, the monitor pin outputs a high level, so that whether the power supply module 20 is mounted on the connection part 11 can be monitored by the change of the level of the monitor pin.
In addition, the monitoring module 13 may also monitor and manage the entire power supply system to obtain the voltage and current of the communication power supply system, and further obtain the system status information to ensure the normal operation of the outdoor communication power supply device 100. In one embodiment, when the power supply module 20 includes a battery module, the monitoring module 13 may also be configured to monitor the temperature and current of the battery to obtain battery status information. In addition, the monitoring module 13 may be further configured to monitor the current of the load 400 to obtain load status information.
Referring to fig. 5 and 6, fig. 5 is a perspective view of an outdoor communication power supply device according to an embodiment of the present application, and fig. 6 is a front view of the base and the power supply module according to fig. 5 in an embodiment. Wherein, each power supply module 20 is provided with a plug-in connection part 21 to realize the installation of the power supply module 20 and the connection part 11. In the embodiment of the present application, the connection portion 11 and the plug portion 21 are waterproof connectors, and further, the sealing connection between the base 10 and the power supply module 20 is realized through the waterproof connectors. Specifically, if the connection portion 11 is a male connector, the insertion portion 21 is a female connector; if the connection portion 11 is a female connector, the insertion portion 21 is a male connector.
Referring to fig. 7 and 8 in combination, fig. 7 is a schematic installation diagram of the power supply module and the base in fig. 6, and fig. 8 is a cross-sectional view of the outdoor communication power supply device in fig. 5 in one embodiment. Specifically, the base 10 includes a housing having a substantially rectangular parallelepiped shape. The housing includes a pair of spaced apart main panels 101 and a plurality of side panels 102 connected end-to-end and between the pair of main panels 101. One of the main panels 101 is provided with at least one connecting portion 11 at intervals, and the other main panel 101 is suspended and mounted on the carrier 200 by a mounting structure 300.
The power supply module 20 is also substantially flat and rectangular parallelepiped, and the plugging portion 21 is disposed on the plugging surface 201, where the plugging surface 201 refers to one end surface of the rectangular parallelepiped power supply module 20 with a smaller area. It will be appreciated that, for aesthetic purposes, the dimension of the main panel 101 in the first direction is the same as the dimension of the end face of the power module 20 provided with the plug-in portion 21 in the first direction, so that the power module 20 is substantially flush with the end of the base 10 after the power module 20 is mounted on the base 10 (as shown in fig. 5). In the present embodiment, the first direction is a longitudinal direction of an end surface of the power supply module 20 where the plug-in portion 21 is provided.
In one embodiment, the plugging surface 201 protrudes in a direction away from the plugging surface 201 along both ends of the first direction to form an elongated flat plate-shaped mounting portion 22, and the mounting portion 22 is provided with a mounting hole 221. Accordingly, the housing of the base 10 is provided with spaced apart fastening holes 14 on a pair of opposed side panels 102.
