[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, the utility model provides a communication base station power box, including a box body 1 and a sealing plate 2 arranged at the lower end of the box body 1.

[0029] like Figure 2As shown, the box body 1 is provided with two rows of parallel external power interfaces 3 and internal electronic interfaces 4 in the enclosed space of the sealing plate 2. The external power interface 3 is used for external power supply, and the internal electronic interface 4 is used for powering the electronic components inside the power box.

[0030] There are at least two external power interfaces 3 and internal electronic interfaces 4 respectively, all external power interfaces 3 are independently distributed, and all internal electronic interfaces 4 are distributed in parallel to form a wiring terminal.

[0031] A shiftable power connection assembly 5 is provided between the external power interface 3 and the internal electronic interface 4. The shiftable power connection assembly 5 is used to connect different external power interfaces 3 to the wiring terminals to replace different power supplies.

[0032] In this embodiment, there are multiple power sources for the communication base station, which can be a substation, a high-voltage transmission line, a regional substation, a distribution transformer, AC power, or a lithium battery. In order to improve the probability of fault tolerance and obstacle avoidance, at least two power sources must be selected to power the communication base station. Therefore, in this embodiment, the number of external power supply interfaces 3 for external power supply is at least two.

[0033] In order to simply and conveniently replace the power supply, this embodiment uses a shiftable power connection assembly 5 as a device for connecting the external power interface 3 and the internal electronic interface 4. The same end of all internal electronic interfaces 4 forms a wiring terminal connected to the electronic components inside the power box. The same group of external power interfaces 3 and internal electronic interfaces 4 constitute a power-on unit.

[0034] When the shiftable power connection assembly 5 is moved to different groups of external power interfaces 3 and internal electronic interfaces 4, different power supplies can be connected to perform power supply work.

[0035] In addition, it should be noted that the function of the sealing plate 2 is to maintain the sealing of the base station power box. When the sealing plate 2 is opened, it is used to replace the power supply, and when the sealing plate 2 is closed, the entire box body 1 forms a sealed structure.

[0036] Furthermore, a baffle plate 6 is provided inside the box body 1 at the upper ends of the external power interface 3 and the internal electronic interface 4, and at least one track 7 is provided on the baffle plate 6 along its length direction. The shiftable power connection component 5 is installed on the track 7 and moves linearly along the track 7.

[0037] The main function of the baffle plate 6 is, on the one hand, to provide a bearing platform for the shiftable power connection assembly 5, and the shiftable power connection assembly 5 can move linearly along the track 7 on the baffle plate 6; on the other hand, the baffle plate 6 is mainly used to protect the electronic components in the power box to form a safe environment isolated from the outside world.

[0038] like Figure 3 As shown, the shiftable power connection assembly 5 includes a base plate 51 and a slot 52 formed in the base plate 51, a connector 53 is installed in the slot 52, and the connector 53 moves in opposite directions along the slot 52 until both ends of the connector 53 are respectively connected to the external power interface 3 and the internal electronic interface 4.

[0039] The connecting member 53 includes a hollow cavity 531 disposed at the center of the slot 52. Two metal guides 532 are installed inside the hollow cavity 531. The metal guides 532 are provided with a push panel 533 at the end close to the hollow cavity 531. Figure 4 As shown, an elastic block 534 is provided on the push panel 533 , and sawtooth grooves 535 are provided on both sides of the slot 52 . The push panel 533 is fixed by the locking action of the elastic block 534 and the sawtooth grooves 535 .

[0040] In this embodiment, the working process of the shiftable power connection assembly 5 is mainly as follows:

[0041] 1. The base plate 51 is mounted on the track 7 and can move linearly along the track 7;

[0042] 2. Use the push panel 533 to drive the two metal guides 532 to move in opposite directions, wherein one metal guide 532 is connected to the external power interface 3, and the other metal guide 532 is connected to the internal electronic interface 4. Since the two metal guides 532 themselves are in full contact under the restriction of the hollow cavity 531, the two metal guides 532 connect the external power interface 3 with the internal electronic interface 4, thereby enabling power connection.

[0043] 3. Due to the locking effect of the elastic block 534 and the sawtooth groove 535, the position of the metal guide 532 will be relatively fixed, thereby ensuring the stability of power connection.

[0044] At least two elastic protrusions 8 are provided on the track 7, and each elastic protrusion 8 corresponds exactly to each group of external power interface 3 and internal electronic interface 4. The elastic protrusion 8 is used to calibrate the position of the shiftable power connection component 5. When the shiftable power connection component 5 moves to the elastic protrusion 8, the two metal guides 532 are pushed in opposite directions until they are respectively connected to the external power interface 3 and the internal electronic interface 4, so that the power can be turned on.

[0045] When the power supply needs to be replaced, the bottom plate 51 needs to continue to move along the track 7 , and continue to push the bottom plate 51 to deform the elastic protrusion 8 until the bottom plate 51 moves to the position of the next elastic protrusion 8 .

[0046] It should be noted that there is a position deviation between the same group of external power interface 3 and internal electronic interface 4, and the position deviation is the same as the vertical distance between the central axes of the two metal guides 532, thereby ensuring the alignment of the metal guide 532 with the external power interface 3 and the internal electronic interface 4.

[0047] Therefore, this embodiment utilizes the linear movement of the shiftable power connection assembly 5 to replace different power supplies to be connected to the power box for power supply, ensuring that only one power supply is connected at the same time, and the method of replacing the power supply is simple and convenient.

[0048] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
