[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments:
[0021] AsFigures 1 to 5 As shown in Figures 1 to 5 , this embodiment provides a power generation device for the balance weight of a pumping unit, which generates electricity by using the rotational mechanical energy of the balance weight 1 of the pumping unit. It includes an annular fence 2, a first permanent magnet 3, a second permanent magnet 4, and an induction coil. An annular fence 2 is fixedly arranged on the outer periphery of the balance weight 1 of the pumping unit. The annular fence 2 is detachably connected to the outer periphery of the balance weight 1 of the pumping unit. Correspondingly, the annular fence 2 is clamped on the outer periphery of the balance weight 1 of the pumping unit. A plurality of first permanent magnets 3 and second permanent magnets 4 are circumferentially arranged at intervals on the inner circumference of the annular fence 2. Both the first permanent magnet 3 and the second permanent magnet 4 are in a columnar structure.
[0022] The annular fence 2 includes a first annular fence and a second annular fence. The first permanent magnets 3 are circumferentially arranged at intervals in the first annular fence, and the second permanent magnets 4 are circumferentially arranged at intervals in the second annular fence. The positive and negative poles of the first permanent magnets 3 and the second permanent magnets 4 are arranged opposite to each other. The first permanent magnets 3 and the second permanent magnets 4 are arranged offset in their circumferential direction to ensure the magnetic field strength. An annular column 5 is arranged on the outside of the annular fence 2. The annular column 5 surrounds the annular fence 2. A wire 6 is wound around the annular column 5 to form an induction coil. When the pumping unit works, the balance weight 1 of the pumping unit rotates, driving the first permanent magnets 3 and the second permanent magnets 4 to rotate. Then, the wire 6 of the induction coil cuts the magnetic induction lines to generate an induced electromotive force, that is, an induced current is generated. The induction coil is connected to an electrical device, and the wire and the electrical device together form a closed circuit. The induced current can be used to drive the electrical device to work. The induction coil is connected to the power grid, and the generated induced current can be fed into the power grid for storage or subsequent use.
[0023] The induction coil is detachably connected to the pumping unit. The induction coil can be clamped or fixed to the pumping unit by silicon steel sheets or bolts to ensure that it surrounds the annular fence 2. Thus, it effectively ensures the change effect of the magnetic flux of the induction coil when the balance weight 1 of the pumping unit rotates, ensuring the power generation effect. At the same time, when work such as well repair and parameter adjustment is carried out on the pumping well, the induction coil can be temporarily disassembled without affecting the normal oil production work of the oil well;
[0024] As an implementable mode, a track (not shown in the figure) is designed between the induction coil and the balance weight 1 of the pumping unit. The induction coil can be slidably arranged along the track. When work such as well repair and parameter adjustment is carried out on the pumping well, the induction coil moves away from the pumping unit through the track, and can be reset after the construction is completed.
[0025] There are two balance weights on the pumping unit. When the present utility model is used, two sets are made and respectively correspond to the balance weights for power generation work.
[0026] During use, the balance weight 1 of the pumping unit rotates continuously, driving the annular fence 2 to rotate, driving the first permanent magnet 3 and the second permanent magnet 4 to rotate. Further, the magnetic induction lines of the rotating first permanent magnet 3 and second permanent magnet 4 cut the wires 6 of the induction coil, generating an induced electromotive force. The induction coil is connected to an electrical device or the power grid for utilizing or storing the generated electrical energy.
[0027] The power generation device of the present utility model is not only applicable to the balance weight of the pumping unit, but can be used for power generation work in any structure that effectively utilizes other rotational mechanical energy.
[0028] The above-described embodiments are only the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features, and principles described within the scope of the patent of the present utility model should be included within the scope of the patent application of the present utility model.
