Holding pole power supply

Abstract

The invention discloses a holding pole power supply. The holding pole power supply comprises a circular ring-shaped box to be installed on a supporting rod; the center of the circular ring-shaped boxis provided with a cylindrical cavity, and the cylindrical cavity is used for encircling the supporting rod; a plurality of battery cells are uniformly arranged inside the circular ring-shaped box; and when the holding pole power supply is installed on the supporting rod, the center of gravity of the holding pole power supply is positioned on the cross section of the supporting rod. Through the implementation of the embodiment, the stability of the holding pole power supply can be improved, and simultaneously, the problem of local overheating caused by the fact that the heat dissipation amongthe battery cells in the holding pole power supply is inconsistent is avoided, so that the service life of the holding pole power supply is prolonged.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a pole-holding power supply. Background technique [0002] Nowadays, with the gradual popularization and commercialization of 4G / 5G, and the development of network technologies such as the Internet of Things and automatic driving, the pole-mounted secondary power supply (referred to as pole-mounted power supply) used to supply power to radio frequency transmitters, cameras, signal lights, etc. ) are in great demand. In the outdoor environment, the existing pole-mounted power supply is usually designed in a square shape and installed on the side of a support pole (such as a utility pole), such as figure 1 As shown, the pole-holding power supply includes a square power box and components such as batteries arranged in the power box, which are installed through connectors and hung on the side of the support pole. However, since the pole-mounted power supply is generally heav...

Problems solved by technology

However, since the pole-mounted power supply is generally heavy, this design and installation method has disadvantages such as unstable center of gravity and large windward area. Especially in bad weather, the pole-mounted power supply has the risk of falling and poor stability; In the power box of this kind of square pole power supply, the layout of the battery cells is usually based on the traditional battery layout method, that is, multiple sets of battery cells are used in parallel, and multiple sets of battery cells are arranged together in a form of stacking and dense arrangement.

However, in this arrangement, the heat dissipation between the cells is uneven, and the temperature difference between the cells is large. It is easy to cause local overheating during the charging and discharging process of the battery, which reduces the performance and service life of the local cells, and even causes local overheating.
