Power generation device that harnesses energy from tree trunk expansion

Abstract

The invention relates to a power generation device utilizing trunk expansion energy. The power generation device comprises a generator, a rotating shaft of the generator is connected with the output end of a gear set for magnifying speed ratio, an input gear of the gear set for magnifying the speed ratio is meshed with an outer gear ring of a spring barrel, the spring barrel is mounted on a spring barrel support which is mounted on a base, a first rope connection port is mounted on one side of the base, a second rope connection port is formed on the other side of the base, one end of a rope is connected with the first rope connection port, the rope is wound on a tree trunk, the other end of the rope penetrates the second rope connection port to be mounted on a rope winding gear which is located in the base and mounted on a rope winding control shaft, and a coil spring is arranged in the rope winding gear. The power generation device utilizing the trunk expansion energy is effectively applicable to forest occasions and good in practicability.

Description

technical field [0001] The invention relates to a power generating device, in particular to a power supply device which is applied to a wireless sensor for forest fire prevention and can solve the problem of the sensor. Background technique [0002] Wireless sensor networks have broad application prospects in environmental monitoring, smart home, transportation, precision agriculture and other fields, and have attracted more and more attention. As an important component of wireless sensor networks, sensor nodes are usually scattered in a certain area to monitor, sense and collect information of various environments and monitoring objects in real time. The sensor node deployment environment and the actual application requirements determine that the node power supply is difficult to connect to the normal power system for power supply in most cases. In addition, because nodes are often placed in harsh and complex environments, the cost of battery replacement is further increas...
