The electromagnetic induction device 2 includes a cylindrical magnet 21 and a copper coil 22, in this embodiment, the cylindrical magnet 21 is a cylinder, the cylindrical magnet 21 is movably and elastically connected to the housing 1, preferably, a suspension spring 23 is disposed below the upper end cover 13, one end of the suspension spring 23 is fixed on the upper end cover 13, the other end of the suspension spring 23 is connected to a magnet base 24, the cylindrical magnet 21 is fixed on the magnet base 24, so that when the turbo drill vibrates, the cylindrical magnet 21 also vibrates along with the suspension spring, the copper coil 22 is fixed under the cylindrical magnet 21, in this embodiment, the copper coil 22 is wound on the lower end cover 14, the electromagnetic induction device 2 is configured to generate a current to power the three-dimensional vibration sensor, specifically, when the cylindrical magnet 21 vibrates up and down, a magnetic flux in the copper coil 22 changes, so that an induced current is generated in the copper coil 22.
Referring to fig. 2 and 3, the first friction nano-generator 3 includes a first PTFE film 31 and a first copper electrode 32, the first copper electrode 32 is fixed on the lower surface of the cylindrical magnet 21, the first PTFE film 31 is located under the first copper electrode 32 and a gap is left between the first PTFE film and the first copper electrode 32, the first PTFE film 31 is attached to the upper surface of the lower end cap 14 and located above the copper coil 22, in this embodiment, since the first PTFE film 31 and the first copper electrode 32 have different electronegativities, when the cylindrical magnet 21 drives the first copper electrode 32 to collide with the first PTFE film 31, a first electrical signal is generated, and the first electrical signal pulse is consistent with the vibration frequency of the cylindrical magnet 21, and at this time, the vibration frequency of the cylindrical magnet 21 is the same as the vibration frequency of the worm wheel, the first friction nano-generator 3 can thus be used to measure the vibration frequency of the worm gear drill in the vertical direction.
The second friction nanometer power generation devices 4 are uniformly distributed in the housing 1, each second friction nanometer power generation device 4 includes a T-shaped collision column 41, an arc blade 42, a second PTFE film 43 and a second copper electrode 44, the T-shaped collision column 41 is located around the cylindrical magnet 21, the T-shaped collision column 41 is connected to the arc blade 42, in this embodiment, a large head end of each T-shaped collision column 41 is close to the cylindrical magnet 21, the other end of each T-shaped collision column passes through the inner casing 11 and is connected to an inner arc surface of the arc blade 42, a return spring 45 is sleeved outside the T-shaped collision column 41, the return spring 45 is located between the large head end of the T-shaped collision column 41 and the inner casing 11, in this embodiment, after the cylindrical magnet 21 collides with any one T-shaped collision column 41, the collided T-shaped collision column 41 automatically returns under the action of the return spring 45 corresponding to the T-shaped collision column, so that each of the T-shaped striking posts 41 can be continuously struck by the columnar magnet 21.

The working principle of the invention is as follows:
before deep well drilling, the three-dimensional vibration sensor is installed on the turbine drilling tool, when the turbine drilling tool vibrates up and down, the columnar magnet 21 also vibrates up and down, so that the first copper electrode 32 and the first PTFE film 31 are in contact with each other, the first electric signal can be generated due to the fact that the two materials are different in electronegativity, the first electric signal pulse is consistent with the vibration frequency of the turbine drilling tool, the vibration frequency of the turbine drilling tool in the vertical direction can be measured through the first friction nano power generation device 3, and at the moment, due to the electromagnetic effect, when the columnar magnet 21 vibrates up and down, the copper coil 22 generates induced current, so that the induced current can be used for supplying power to the three-dimensional vibration sensor; when the turbo drill vibrates horizontally, the columnar magnet 21 also vibrates horizontally and impacts one of the T-shaped impact columns 41 around the columnar magnet, at this time, the T-shaped impact column 41 drives the fan-shaped blade 41 connected with the columnar magnet to move radially, causing the second PTFE membrane 43 on the fan-shaped blade 41 to impinge on the second copper electrode 44, thereby generating the second electrical signal, because the four T-shaped collision columns 41 are arranged on the periphery of the columnar magnet 21, the vibration frequency of the worm gear drilling tool in the horizontal direction and the front-back direction can be measured, therefore, the vibration frequency of the worm gear drilling tool in the three-dimensional direction can be obtained by the working principle, in addition, the electric quantity generated by the first friction nano power generation device 3 and the second friction nano power generation device 4 of the quagsanju tree can be collected, so that the three-dimensional vibration sensor or other components can be powered.
According to the three-dimensional vibration sensor based on the friction nano generator and the electromagnetic induction, the vibration frequencies of the worm gear drilling tool in the vertical direction, the horizontal direction and the front and back directions are measured through the first friction nano generator 3 and the fourth friction nano generator 4 respectively, so that the worm gear drilling tool is monitored in real time, the three-dimensional vibration frequency of the worm gear drilling tool is obtained, and therefore abnormality can be found in time and the worm gear drilling tool can be adjusted; in addition, the invention can generate induction current through the electromagnetic induction device 2, thereby supplying power to the three-dimensional vibration sensor.
