Abstract

A power generator device utilizing residual potential energy comprises a support frame (1), a driven wheel (4), a crank mechanism (5), and a power generator (9). The crank mechanism (5) is fitted on the support frame (1). The driven wheel (4) is disposed at a front end of the crank mechanism (5). A driven wheel center shaft (10) is fixedly installed at the center of the driven wheel (4). An eccentric shaft (11) of the driven wheel is fixedly installed at an eccentric position of the driven wheel (4). The driven wheel (4) is rotatably connected to a belt pulley at a front end of an output shaft of the power generator (9) via a conveyor belt. The power generator device utilizing residual potential energy has a novel design. A motor (2) fitted on a beam pumping unit converts electrical energy of the pumping unit into mechanical energy. During a down stroke of the beam pumping unit, the weight of an underground sucker rod (8) of the pumping unit converts lifting potential energy into a free-fall movement, and part of the potential energy is converted into kinetic energy under the action of a balancing block. The potential energy for underground oil pumping during the down stroke is greater than the partially converted kinetic energy. The invention utilizes the residual potential energy means to convert the unconverted potential energy into electrical energy, thereby realizing energy harvesting and conversion.

Power generation device using residual potential energy

Technical field

The invention relates to a power generating device, in particular to a power generating device using residual potential energy.

Background technique

Beam pumping unit, also known as beam pumping unit, beam-type crank balance pumping unit, refers to a pump unit that contains a beam, which is commutated by a link mechanism, and the crank weight is balanced, commonly known as a hoe. In terms of oil extraction methods, there are rod-type oil extraction equipment (in terms of oil extraction methods, they can be divided into two categories, that is, rod-type oil extraction equipment and non-rod-type oil extraction equipment).

Power generation is the conversion of hydropower, fossil fuel (coal, oil, natural gas, etc.) thermal energy, nuclear energy, solar energy, wind energy, geothermal energy, ocean energy, etc. into electricity using power generation power devices. Fossil fuels are currently used for power generation, but there are not many fossil fuel resources and they are depleting. Humans have gradually used renewable energy sources (hydropower, solar energy, wind energy, geothermal energy, ocean energy, etc.) to generate electricity. At present, everyone is familiar with Wind power and solar power have inadequate aspects. When there is no wind, wind power cannot be used to generate electricity. When there is no sun or rainy days, solar power cannot generate power. The beam pumping unit can generate potential energy during the working process. It is then converted into kinetic energy, but potential energy is partially lost in the process of being converted into kinetic energy.
