[0015] The beneficial effects of the present invention are:

[0016] 1. In the present invention, the energy-saving and explosion-proof intelligent electromagnetic wax prevention device for oil wellheads is powered by a superconducting coil through an energy storage power supply, so that the superconducting coil generates a 0.1-10THz tunable electromagnetic pulse. When the electromagnetic field frequency forms a quantum resonance with the vibration frequency of the CH bond of the wax molecule (2.47THz), the activation energy of paraffin crystallization is increased, which fundamentally inhibits the formation of crystal nuclei. At the same time, a strong magnetic field is established through the superconducting coil to exert a strong excitation effect on the paraffin molecules in the crude oil, thereby achieving the effect of preventing and removing wax. Hydrocarbons have high magnetism. When the external magnetic field is perpendicular to the plane of the paraffin molecules, the magnetically treated crude oil can cause the wax crystal molecules and their clusters to undergo magnetic induction resonance, thereby producing a destructive scattering effect. This effect reduces the possibility of paraffin molecules precipitating and crystallizing on the pipe wall. Secondly, under the action of a magnetic field of a certain intensity, the hydrogen bonds of paraffin may change. This change can interrupt the hydrogen bonds between paraffin molecules, thereby changing their structure and strength, making it difficult to form a stable skeleton. This mechanism effectively inhibits the aggregation phenomenon between wax crystals, thereby achieving the purpose of preventing wax;

[0017] 2. In the present invention, the energy-saving explosion-proof oil wellhead intelligent electromagnetic wax prevention device introduces the liquid nitrogen in the liquid nitrogen storage tank into the connecting shell by starting the pump body, and introduces it into the explosion-proof shell through the connecting pipe to cool the superconducting coil, thereby maintaining the ultra-low temperature use environment of the superconducting coil. Subsequently, the liquid nitrogen is discharged through the outlet pipe, and when the liquid nitrogen flows through the connecting shell, it drives the toggle blade to rotate, and drives the horizontal axis and the first bevel gear to rotate. The first bevel gear drives the vertical axis to rotate through the meshing with the second bevel gear. The vertical axis drives the two circular rings to rotate in opposite directions through the meshing of the third bevel gear and the two bevel gear rings, and drives the corresponding arc-shaped dispersion blades to rotate. The arc-shaped dispersion blades push the liquid nitrogen to fully circulate in the explosion-proof shell to ensure the cooling efficiency and uniformity of the superconducting coil.

[0018] 3. In the present invention, for the intelligent electromagnetic paraffin prevention device for energy-saving explosion-proof oil production wellheads, the dielectric constant of crude oil is monitored by a quantum Hall effect sensor, the temperature inside the pipe is monitored by a temperature sensor, and the detection results are transmitted to the controller. The controller analyzes the sensor information, inversely calculates the crystallization trend of wax molecules in real time, and adjusts the working voltage and frequency of the energy storage power supply in real time according to the analysis results, so as to adjust the frequency and intensity of the magnetic field generated by the superconducting coil to meet the paraffin prevention requirements;

[0019] 4. In the present invention, for the intelligent electromagnetic paraffin prevention device for energy-saving explosion-proof oil production wellheads, solar energy is received by a photovoltaic panel and converted into electrical energy, which is then stored in a storage battery. The storage battery supplies power to the controller pump body and the energy storage power supply. The telescopic movement of the electric push rod drives the support seat and the photovoltaic panel to rotate around the vertical plate, thereby adjusting the angle of the photovoltaic panel in real time to ensure the photovoltaic power generation efficiency;

[0020] 5. In the present invention, for the intelligent electromagnetic paraffin prevention device for energy-saving explosion-proof oil production wellheads, by controlling the rotation of the rotating ring and driving a plurality of clamping plates to move away from each other through the cooperation of the arc-shaped groove and the corresponding connecting column, the clamping plates are disengaged from the clamping grooves, and the compression spring is compressed, thereby releasing the fixation of the positioning flange. Then it can be moved horizontally, and the positioning flange and the heat preservation cover are used to remove the explosion-proof shell from the outside of the pipe for convenient cleaning and maintenance;

[0021] 6. In the present invention, for the intelligent electromagnetic paraffin prevention device for energy-saving explosion-proof oil production wellheads, the superconducting coil can form a strong magnetic field in the crude oil pipeline to achieve the effect of paraffin prevention. The cooling mechanism and the dispersion mechanism can realize the efficient cooling of the superconducting coil to ensure the continuous working effect. The photovoltaic power generation mechanism improves the energy conservation and environmental protection performance of the paraffin prevention device, and the installation mechanism facilitates disassembly and maintenance.

[0047] In this embodiment, during use, the superconducting coil 9 is powered by the energy storage power supply 16, so that the superconducting coil 9 generates an adjustable electromagnetic pulse of 0.1 - 10 THz. When the electromagnetic field frequency forms a quantum resonance with the vibration frequency (2.47 THz) of the C-H bond of the paraffin molecule, the activation energy of paraffin crystallization is increased, fundamentally inhibiting the formation of crystal nuclei. At the same time, a strong magnetic field is established through the superconducting coil 9 to exert a strong excitation effect on the paraffin molecules in the crude oil, thereby achieving the effect of preventing and removing wax. Hydrocarbons have relatively high magnetism. When the external magnetic field is perpendicular to the plane of the paraffin molecules, the magnetically treated crude oil can cause the paraffin crystal molecules and their clusters to undergo magnetic induction resonance, and then produce a destructive scattering effect. This effect reduces the possibility of paraffin molecules precipitating and crystallizing on the pipe wall. Secondly, under the action of a magnetic field of a certain intensity, the hydrogen bonds of paraffin may change.

The liquid nitrogen is then discharged through the outlet pipe 13, and when the liquid nitrogen flows through the connecting shell 203, it drives the paddle 507 to rotate, and drives the horizontal shaft 506 and the first bevel gear 508 to rotate. The first bevel gear 508 drives the vertical shaft 504 to rotate by meshing with the second bevel gear 509. The vertical shaft 504 drives the two circular rings 501 to rotate in the opposite direction through the meshing of the third bevel gear 510 and the two bevel gear rings 503. The arc-shaped dispersion blades 502 are driven to rotate in the explosion-proof housing 8, and the liquid nitrogen is fully circulated in the explosion-proof housing 8 through the arc-shaped dispersion blades 502 to ensure the cooling efficiency and uniformity of the superconducting coil 9. The dielectric constant of the crude oil is monitored through the quantum Hall effect sensor 12, and the temperature in the pipe body 1 is monitored through the temperature sensor 11.
