Description
Technical Field
[0001] This utility model relates to the field of energy-saving technology for oil pumping units, specifically to a solar photovoltaic energy-saving device for oil pumping units. Background Technology
[0002] A solar photovoltaic energy-saving device for oil pumping units is a device that uses solar photovoltaic power generation technology to provide power to oil pumping units. As described in Chinese patent application CN116032192A, this technical solution can transmit electrical energy to different batteries for storage as needed. After the batteries have stored enough power, the control system controls the current to be stored in other batteries that are not fully charged. At the same time, a moving block connects to the fully charged batteries, and the current is transmitted to the inverter through the load interface. The inverter converts the current form and supplies it to the oil pumping unit. When encountering adverse conditions such as cloudy or rainy weather or poor sunlight, the power grid connected through the grid interface supplies power to the oil pumping unit with grid current.
[0003] However, the following problems still exist in this technical solution: the heat dissipation holes in this technical solution dissipate heat inside the device cabinet, but external dust enters the device cabinet through the heat dissipation holes and adheres to the electrical components, which can easily affect the heat dissipation of the electrical components.

The solar panel 508 is electrically connected to the first controller 504. A second controller 505 is installed inside the first placement slot 501. An inverter 506 is installed on the rear side of the second controller 505. The inverter 506 is electrically connected to a load interface 507. The load interface 507 is fixed on one side of the inverter 506. One side of the load interface 507 extends out of one side of the power supply box 1. Both the first controller 504 and the second controller 505 are electrically connected to the storage battery 503.
[0031] The electrical energy converted by the solar panel 508 is transmitted to the first controller 504, and then the first controller 504 transmits the electrical energy to the storage battery 503 for storage. After the storage battery 503 stores enough electricity, the current is transmitted through the storage battery 503 to the second controller 505, and then enters the inverter 506 through the second controller 505. The inverter 506 converts the current form and supplies it to the oil pumping unit.

The filter 204 filters dust in the outside air to prevent dust from adhering to the power supply mechanism 5 and affecting the heat dissipation effect. When the filter 204 needs to be replaced, turn the bolt 207 to turn the bolt 207 out from the first threaded hole 205 and the second threaded hole 206, and the filter 204 can be removed from the connecting frame 202 for replacement.
