一种示功仪供电装置、安装方法和抽油机
摘要：
本发明公开了一种示功仪供电装置、安装方法和抽油机，属于抽油机示功仪领域。所述装置与示功仪相连接，安装于悬绳器上，所述装置包括：发电组件、与所述发电组件连接的蓄电组件；所述发电组件包括壳体、位于所述壳体内部的永磁铁、将所述永磁铁与所述壳体连接的弹簧、位于所述永磁铁附近的金属线圈；所述金属线圈与所述永磁铁的磁感线之间有预设的角度。所述安装方法为：按照所述发电组件中弹簧的长度方向与光杆的长度方向一致的方式安装所述示功仪供电装置。所述抽油机包括所述示功仪供电装置。本发明通过金属线圈会切割永磁铁的磁感线产生电流，实现了不用更换电池而长期为示功仪供电。
摘要（英）：

The invention discloses a dynamometer power supply device, an installation method thereof and a pumping unit, and belongs to the field of oil pumping unit dynamometers. The dynamometer power supply device is connected with a dynamometer and installed on a beam hanger. The dynamometer power supply device comprises a power generation assembly and a power storage assembly connected with the power generation assembly, wherein the power generation assembly comprises a housing, a permanent magnet located inside the housing, springs connecting the permanent magnet and the housing and metal coils nearthe permanent magnet; and a preset angle is reserved between the metal coils and magnetic induction lines of the permanent magnet. The installation method comprises that the dynamometer power supplydevice is installed according to a mode that the length direction of the springs in the power generation assembly is consistent with the length direction of a polished rod. The oil pumping unit comprises the dynamometer power supply device. The metal coils cut the magnetic induction lines of the permanent magnet to generate current, so that the dynamometer power supply device can provide power forthe dynamometer for a long time without changing a battery.
