Detailed Implementation

[0018] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0019] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0020] The present invention will be further described below with reference to embodiments and accompanying drawings: As attached Figure 1As shown, the wellhead insulation and heating device includes a power drive unit 1, a strong magnet 2, a spiral copper tube 3, and a heat exchanger 4. The strong magnet 2 is fixedly installed on the power output end of the power drive unit 1. The spiral copper tube 3 is located near the strong magnet 2. One end of the spiral copper tube 3 is fixedly installed together with the liquid inlet end of the heat exchanger 4, and the other end of the spiral copper tube 3 is fixedly installed together with the liquid outlet end of the heat exchanger 4. The strong magnet 2, the spiral copper tube 3, and the heat exchanger 4 are all existing and publicly known components. The strong magnet 2 and the spiral copper tube 3 can both be disc-shaped, and their proximity can be adjusted according to actual conditions. Based on the principle of electromagnetic induction, the strong magnet 2 rotates, and the spiral copper tube 3 heats up, causing the antifreeze liquid inside to circulate and dissipate heat in the heat exchanger 4, thereby providing insulation heat for the oil and water wellheads. In this way, through the combined use of the power drive device 1, the strong magnet 2, the spiral copper tube 3, and the heat exchanger 4, the residual energy of the pumping unit or clean energy is used for heating and insulation, preventing freezing and blockage of the oil and water wellhead equipment, ensuring the safety of oilfield equipment in winter, and featuring safety, reliability, and environmental protection. It also facilitates operation, reduces operating costs, and eliminates electrical safety hazards.

[0021] Example 1, as shown in the attached document Figure 2 As shown, the power drive device 1 includes a right-angle bevel gear box 5 and a friction wheel 6; the power input end of the right-angle bevel gear box 5 and the friction wheel 6 are connected together by a flexible shaft 7, and a strong magnet 2 is fixedly installed on the power output end of the right-angle bevel gear box 5. Both the right-angle bevel gear box 5 and the friction wheel 6 are existing and publicly known.

[0022] Example 1 can be further optimized and / or improved according to actual needs: As attached Figure 2 As shown, the power input end of the right-angle bevel gear box 5 and the flexible shaft 7 are fixedly mounted together by a coupling 8. This coupling 8 facilitates installation.

[0023] As attached Figure 2 As shown, a base 9 is fixedly installed at the bottom of the right-angled bevel gear box 5. The base 9 makes the right-angled bevel gear box 5 more stable.

[0024] During operation, the friction wheel 6 can rotate by friction with moving parts such as the pulley, belt or polished rod of the pumping unit. Through the transmission of the flexible shaft 7, it drives the strong magnet 2 on the right-angle bevel gear box 5 to rotate. Due to electromagnetic induction, the spiral copper tube 3 heats up, causing the antifreeze liquid inside to circulate and dissipate heat in the heat exchanger 4, thereby providing heat preservation for the oil and water wellhead.

[0025] Example 2, as shown in the attached document Figure 3As shown, the power drive device 1 includes a solar panel 10, a rechargeable battery 11, and a motor 12. The rechargeable battery 11 is connected to the solar panel 10 and the motor 12 via wires 13. A strong magnet 2 is fixedly installed on the power output end of the motor 12. The solar panel 10, the rechargeable battery 11, and the motor 12 are all existing and publicly known components. Thus, the strong magnet 2 can be rotated by the solar panel 10 or a small wind turbine, or the strong magnet 2 can be directly rotated by the pumping unit motor. This can also heat up the spiral copper pipe 3, causing the heat-conducting liquid inside to circulate in the heat exchanger 4 after being heated, thereby providing the required heat for the oil and water wellhead.

[0026] Example 2 can be further optimized and / or improved according to actual needs: Depending on the requirements, motor 12 can be a miniature motor for easy movement or operation.

[0027] As attached Figure 3 As shown, a base 9 is fixedly installed at the bottom of the motor 12. The base 9 makes the motor 12 more stable.

[0028] As attached Figure 1 , 2 As shown in Figure 3, one end of the spiral copper tube 3 and the liquid inlet end of the heat exchanger 4 are fixedly installed together through the first connecting pipe 14, and the other end of the spiral copper tube 3 and the liquid outlet end of the heat exchanger 4 are fixedly installed together through the second connecting pipe 15. A liquid flow pipe 16 is fixedly installed on the second connecting pipe 15, and a valve 17 is fixedly installed on the liquid flow pipe 16. In this way, the liquid flow pipe 16 is used for filling the heat transfer fluid and venting the air in the heat exchanger 4.

[0029] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
