The embodiments relate to the field of power supply technologies, and in particular, to a pole-mounted power supply.
Currently, with the gradual popularization and commercial use of 4G/5G and the development of network technologies such as the Internet of Things and self-driving, there is a very large demand for a pole-mounted secondary power supply (a pole-mounted power supply for short) used to supply power to a radio frequency transmitter, a camera, a signal light, and the like. In an outdoor environment, an existing pole-mounted power supply is usually designed as a square, and is mounted on a side face of a support pole (such as a utility pole). As shown in
Embodiments provide a pole-mounted power supply, so that stability of the pole-mounted power supply can be improved, and a problem of local overheating caused by inconsistent heat dissipation between electrochemical cells in the pole-mounted power supply is avoided, thereby prolonging a service life of the pole-mounted power supply.
According to a first aspect, an embodiment provides a pole-mounted power supply. The pole-mounted power supply includes an annular tank to be mounted on a support pole, there is a cylindrical cavity at a center of the annular tank, the cylindrical cavity is configured to encircle the support pole, a plurality of electrochemical cells are evenly disposed in the annular tank, and a center of gravity of the pole-mounted power supply is located on a cross section of the support pole when the pole-mounted power supply is mounted on the support pole. For example, in the annular tank, centers of gravity of the plurality of electrochemical cells are evenly distributed around a center line of the cylindrical cavity. In this way, when the pole-mounted power supply is mounted on the support pole, the center of gravity (F) of the pole-mounted power supply is located on the cross section of the support pole. In a possible embodiment, the center of gravity of the pole-mounted power supply even can be located at a center of the cross section of the support pole. The cross section is located inside the support pole, and the cross section is perpendicular to the center line of the cylindrical cavity.
It can be learned that, in this embodiment, the pole-mounted power supply is designed as the annular tank having the cylindrical cavity at the center, so that the pole-mounted power supply can encircle the support pole after being mounted on the support pole. In addition, because the plurality of electrochemical cells of the pole-mounted power supply are evenly arranged in the annular tank, the center of gravity of the pole-mounted power supply can be located on the cross section (even the center) of the support pole. Therefore, through implementation of this embodiment, stability of the pole-mounted power supply can be improved. In addition, because the electrochemical cells are evenly distributed, surrounding environments of all the electrochemical cells are basically consistent, and therefore, heat dissipation situations of all the electrochemical cells are also basically consistent, thereby avoiding a problem of local overheating caused by inconsistent heat dissipation between the electrochemical cells, and prolonging a service life of the pole-mounted power supply.
In an embodiment, the annular tank is divided into two semi-circular columnar structures, a movable hinge is disposed at a first junction of the two semi-circular columnar structures, and the two semi-circular columnar structures are movably connected by using the movable hinge. An adjustable fastening structure is disposed at a second junction of the two semi-circular columnar structures, and when the two semi-circular columnar structures are closed into the annular tank by using the movable hinge, the adjustable fastening structure is configured to lock the annular tank.
In this embodiment, for a plurality of electrochemical cells to be evenly disposed in the annular tank, in the annular tank, centers of gravity of the plurality of electrochemical cells are evenly distributed around the center line of the cylindrical cavity. For example, the plurality of electrochemical cells in internal space of the annular tank have various arrangement manners.
In a possible arrangement manner, a plurality of square electrochemical cells or soft-package electrochemical cells (for example, 16 square electrochemical cells) are arranged in the internal space of the annular tank, each electrochemical cell has an electrochemical cell tab, the electrochemical cell tab is arranged upwards on a surface of the electrochemical cell, and busbars of electrochemical cell tabs of different electrochemical cells are connected by using a soft connection (for example, a wire connection) or a hard connection (for example, a copper sheet connection). Centers of gravity of these electrochemical cells are evenly distributed around the center line of the cylindrical cavity of the annular tank. For example, these electrochemical cells are radially distributed in the internal space around the center line of the cylindrical cavity. A maximum cross section of each electrochemical cell is coplanar with the center line of the cylindrical cavity. An included angle between respective maximum cross sections of adjacent electrochemical cells is 22.5°, and a sum of these included angles is 360°. In a possible embodiment, n layers of pole-mounted power supplies may be designed based on an actual power consumption requirement. In this case, it may be understood that a sum of included angles 7 of all the pole-mounted power supplies is n times 360°, where n is an integer greater than or equal to 1.
In another possible arrangement manner, a plurality of square electrochemical cells or soft-package electrochemical cells (for example, eight square electrochemical cells) are arranged in the internal space of the annular tank, each electrochemical cell has an electrochemical cell tab, the electrochemical cell tab is arranged upwards on a surface of the electrochemical cell, and busbars of electrochemical cell tabs of different electrochemical cells are connected by using a soft connection (for example, a wire connection) or a hard connection (for example, a copper sheet connection). For example, these electrochemical cells are distributed in the internal space around the center line of the cylindrical cavity in a rotary (or helical) manner, and a maximum cross section of the electrochemical cell is not coplanar with the center line of the cylindrical cavity. An included angle between respective maximum cross sections of adjacent electrochemical cells is 45°, and a sum of these included angles is 360°. In a possible embodiment, n layers of pole-mounted power supplies may be designed based on an actual power consumption requirement. In this case, it may be understood that a sum of included angles 16 of all the pole-mounted power supplies is n times 360°, where n is an integer greater than or equal to 1.
In still another possible arrangement manner, a plurality of cylindrical electrochemical cells (for example, 64 electrochemical cells) are arranged in the internal space of the annular tank, each electrochemical cell has an electrochemical cell tab, the electrochemical cell tab is arranged upwards on a surface of the electrochemical cell, and busbars of electrochemical cell tabs of different electrochemical cells are connected by using a soft connection (for example, a wire connection) or a hard connection (for example, a copper sheet connection). Centers of gravity of these electrochemical cells are evenly distributed around the center line of the cylindrical cavity of the annular tank. For example, a center line of each cylindrical electrochemical cell is parallel to the center line of the cylindrical cavity. These electrochemical cells are radially distributed in the internal space around the center line of the cylindrical cavity, and one group of electrochemical cells are evenly disposed on each radial line. An included angle between a plane constituted by a center line of a group of electrochemical cells on a same radial line and the center line of the cylindrical cavity and a plane constituted by a center line of a group of electrochemical cells on adjacent radial lines and the center line of the cylindrical cavity is 22.5°, and a sum of these included angles 16 is 360°.
In a possible embodiment, n layers of pole-mounted power supplies may be designed based on an actual power consumption requirement. In this case, it may be understood that a sum of included angles of all the pole-mounted power supplies is n times 360°, where n is an integer greater than or equal to 1.
In addition, in this embodiment, the pole-mounted power supply may be mounted on the support pole in various manners. Before mounting, the movable hinge is in a movable connection state, and after mounting, the movable hinge is fixedly fastened to the adjustable fastening structure on the other end. The pole-mounted power supply may be fastened to the support pole based on a structure of the pole-mounted power supply, or may be fastened to the support pole by using a peripheral upper base component and a peripheral lower base component.
In a possible mounting manner, the cylindrical cavity may be configured to clamp the support pole. When the pole-mounted power supply is mounted on the support pole, the adjustable fastening structure is fastened, so that a cavity wall of the cylindrical cavity can be in close contact with the support pole. In other words, when the pole-mounted power supply is mounted on the support pole, a radius of the cylindrical cavity is equal to a radius of a mounting position of the support pole. In this way, the pole-mounted power supply can be fastened to the support pole by using friction between the cavity wall and the support pole.
In another possible mounting manner, the pole-mounted power supply may be fastened to the support pole by using a peripheral component. For example, an angle steel is disposed on each of two ends of the cylindrical cavity of the annular tank of the pole-mounted power supply (in other words, the angle steel is disposed on each of a top edge and a bottom edge of a cavity part of each semi-circular columnar structure). When the pole-mounted power supply needs to be mounted on the support pole, one side of the angle steel is fixedly connected to the annular tank, and the other side of the angle steel is in close contact with the support pole. Angle steels on top edges of cavity parts of the two semi-circular columnar structures are separately set to be connected by using fastening studs, and angle steels on bottom edges of the cavity parts of the two semi-circular columnar structures are also separately set to be connected by using fastening studs. In this way, after being mounted, the pole-mounted power supply may also be fastened to the support pole by using a peripheral component.
In another embodiment, the support pole may not be standardized, and the support pole may have different diameters. Also, regardless of a change of the support pole, at least one second support pole with a standard diameter may be connected. In this case, the pole-mounted power supply may also be mounted on the second support pole. In this case, an equivalent effect is achieved. In still another embodiment, there are uneven diameters on a top part and a bottom part of the support pole. Generally, the diameter gradually decreases from bottom to top. In this case, a ring in the middle of the pole-mounted power supply may also be gradient, so that the ring can be naturally fastened on the pole (
In an embodiment, in addition to the electrochemical cells, other conventional power auxiliary components such as a Battery Management System (BMS), a busbar, a heating film, and a necessary reinforcing piece are disposed in the annular tank in this embodiment. These power auxiliary components are located between the electrochemical cells, or located on an upper part of the electrochemical cell, or located on a lower part of the electrochemical cell, or located on a surface of the electrochemical cell. This is not specifically limited herein.
It can be learned that, in the embodiments, the pole-mounted power supply is designed as the annular tank having the cylindrical cavity at the center, so that the pole-mounted power supply can encircle the support pole after being mounted on the support pole. In addition, because the plurality of electrochemical cells of the pole-mounted power supply may be evenly arranged in the annular tank in a plurality of deployment manners, the center of gravity of the pole-mounted power supply can be located on the cross section (even the center) of the support pole. Therefore, through implementation of the embodiments, stability of the pole-mounted power supply can be improved, and impact from severe weather is avoided. In addition, because the electrochemical cells are evenly distributed, surrounding environments of all the electrochemical cells are basically consistent, and working temperature is also consistent, so that it is ensured that temperature between the electrochemical cells is consistent, in other words, heat dissipation situations of all the electrochemical cells are basically consistent, thereby avoiding a problem of local overheating caused by inconsistent heat dissipation between the electrochemical cells, and prolonging the service life of the pole-mounted power supply. In addition, it can be learned from the plurality of deployment manners of the electrochemical cells described above that the pole-mounted power supply provided in the embodiments has relatively strong expandability, can be widely applicable to an application scenario with increasing requirements for an electric quantity such as a 5G scenario, and has relatively strong applicability.

In this embodiment, the movable hinge 5 and the fastening structure 6 are disposed on the annular tank 1 of the pole-mounted power supply, and the annular tank may be divided into two semi-circular columnar structures (201 and 202). The movable hinge 5 is disposed at a junction (an overlapping position) of ends of the two semi-circular columnar structures, and the two semi-circular columnar structures are movably connected by using the movable hinge 5. The adjustable fastening structure 6 is disposed at a junction (an overlapping position) of the other ends of the two semi-circular columnar structures, and when the two semi-circular columnar structures are closed into the annular tank 1 by using the movable hinge 5, the adjustable fastening structure 6 is configured to lock the annular tank 1. Because the pole-mounted power supply (the annular tank 1) can be opened into the two semi-circular columnar structures based on the movable hinge 5, it is convenient to arrange the electrochemical cells in the corresponding internal space 2, and it is convenient to mount the pole-mounted power supply on the support pole.

This is not specifically limited herein. Regardless of an arrangement manner, because total weight of the electrochemical cells is a main part of weight of the pole-mounted power supply, the center of gravity of the ring-shaped columnar pole-mounted power supply in this embodiment can be kept on the cross section of the support pole 10.
In this embodiment, the pole-mounted power supply may be mounted on the support pole 10 in various manners. Before mounting, the movable hinge 5 is in a movable connection state, and after mounting, the movable hinge 5 is fixedly fastened to the adjustable fastening structure 6 on the other end. The pole-mounted power supply may be fastened to the support pole 10 based on a structure of the pole-mounted power supply, or may be fastened to the support pole 10 by using a peripheral upper base component and a peripheral lower base component.
