[0002] The magnetotelluric field refers to the electric and magnetic fields in the earth's natural electromagnetic field that change with time. Its period range is extremely wide. The magnetotelluric field is caused by external factors of the earth, that is, the electromagnetic effect caused by the particle flow and electromagnetic radiation continuously emitted by the sun in the space around the earth. These external factors include natural phenomena such as solar wind (solar particle radiation flow with high conductivity) and lightning.

[0003] The magnetotelluric sounder is an important tool for performing magnetotelluric sounding, which uses natural alternating electromagnetic fields to study the electrical structure of the earth. Its working principle is to use the natural alternating electromagnetic field as the field source and infer the electrical structure and depth information of underground rock formations by measuring the changes in the electromagnetic field at a certain point on the surface or underground.

[0004] At present, when the existing magnetotelluric depth sounder is in use, since the electrode rod and the conductor are designed to be separated, the electrode rod needs to be placed in the ground in advance before it can be stabilized. When placing the electrode rod, it needs to rely on staff to pick it up and move it. As a result, when the existing magnetotelluric depth sounder is in use, it is impossible to place the electrode rod in position and make holes in position. Therefore, a device is needed to improve the above problem. Summary of the invention

[0037] As Figure 7 , the displacement device 16 includes a guide rail 36, a limit plate 37, a supporting cavity 38 and a driving wheel 39.

[0039] The working principle of Embodiment 1 is as follows: When in use, first move the support wing frame 2 and the magnetotelluric detector 3 to the designated test area, and then move the entire guiding mechanism 1 inside the support wing frame 2 away from the magnetotelluric detector 3. At the same time, the conductive wire inside the magnetotelluric detector 3 can be connected to the top end of the electrode rod 31, so that the data of the electrode rod 31 during operation can be transmitted to the inside of the magnetotelluric detector 3. Subsequently, when the electrode rod 31 needs to work, the driving wheel 39 can be started, so that the driving wheel 39 can drive the support cavity 38 to displace. When the support cavity 38 moves to the designated test area, through the control switches installed inside the magnetotelluric detector 3 and matching with the driving motor 27 and the hydraulic cylinder 35, the driving motor 27 can be started first to drive the lead screw 23 to rotate. Since the support base plate 8 is threadedly sleeved on the outer ring of the lead screw 23, when the lead screw 23 rotates clockwise, the support base plate 8 can be driven to move downward. At this time, when the support base plate 8 moves downward, it can drive the first rack 6 to displace along the second gear 19, thereby driving the second gear 19 and the third gear 26 to rotate simultaneously, so that the winding wheel 25 can be released. The elasticity of the return spring 33 will drive the displacement bracket 32 to displace towards the end away from the support top frame 17, thereby avoiding interference between the drill 11 and the electrode rod 31 when the drill 11 moves downward. At the same time, when the support base plate 8 moves downward, it can drive the first gear 12 to move downward along the surface of the second rack 24. Thus, the first gear 12 can drive the worm 9 to rotate. When the worm 9 rotates, it can drive the worm gear 10 to rotate, so that the drill bit of the drill 11 can rotate downward. When the first gear 12 completely passes over the second rack 24, the drill bit of the drill 11 can rotate to be vertically downward. Due to the self-locking property between the support base plate 8 and the worm 9, the drill 11 can be prevented from shaking. Subsequently, when the support base plate 8 continues to move downward, it can drive the photoelectric sensor 13 to contact the contact frame 21, so that the photoelectric sensor 13 can sense the signal, thereby starting the drill 11, causing the drill bit inside the drill 11 to rotate. Subsequently, when the support base plate 8 continues to move downward, it can drive the drill bit in the drill 11 to penetrate the through hole at the bottom end of the support cavity 38 and contact the ground, thereby drilling a hole in the ground. And, before the support base plate 8 moves downward to the limit position, the photoelectric sensor 13 can always be located on the surface of the contact frame 21, thereby ensuring that the drill 11 is in a working state. Subsequently, when a hole is drilled in the ground, the driving motor 27 can be started again to drive the lead screw 23 to rotate counterclockwise, so that the lead screw 23 can drive the support base plate 8 to displace upward, so that the drill 11 can be withdrawn from the ground. Subsequently, when the photoelectric sensor 13 passes upward through the contact frame 21, the drill 11 can be powered off. Subsequently, when the support base plate 8 continues to displace upward, it can drive the first gear 12 to contact and mesh with the second rack 24, so that when the support base plate 8 moves upward subsequently, the first gear 12 can rotate in the reverse direction, so that the worm gear 10 can drive the drill 11 to flip upward again.It is convenient to rotate the drill bit part in the drilling machine 11 upward. At the same time, when the support substrate 8 continues to move upward, it can drive the first rack 6 to contact and mesh with the second gear 19, so as to drive the second gear 19 and the third gear 26 to rotate simultaneously. When the winding wheel 25 rotates, it can pull the displacement bracket 32 to displace towards the end close to the support top frame 17, so that the electrode rod 31 can approach the ground opening. When the support substrate 8 moves upward and resets, it can drive the drilling machine 11 to move upward to the limit position. Moreover, the bottom tooth of the first rack 6 can mesh with the second gear 19, so as to prevent the second gear 19 from rotating again. At the same time, the winding wheel 25 can pull the connecting rope 29 to displace to the limit position, so that the bottom end of the electrode rod 31 can be vertically aligned with the hole in the ground. At this time, the control switch of the hydraulic cylinder 35 can be started, so that the piston rod inside the hydraulic cylinder 35 can move downward until the bottom end of the electrode rod 31 is inserted into the hole in the ground, so that the electrode rod 31 can carry out normal detection work. Subsequently, when the electrode rod 31 completes the detection work, the control switch of the hydraulic cylinder 35 can be turned on again, so that the hydraulic cylinder 35 can drive the electrode rod 31 to reset upward, which is convenient to remove the electrode rod 31 from the hole in the ground. Then, the drive motor 27 is started to drive the lead screw 23 to rotate clockwise, so that the support substrate 8 can move downward. Until the support substrate 8 drives the first rack 6 to pass downward through the second gear 19, the connecting rope 29 can be completely released, so that the return spring 33 can pull the electrode rod 31 to move until it fits with the limiting plate 37, completing the reset work of the electrode rod 31. And when the support substrate 8 drives the first rack 6 to completely pass through the second gear 19, it can drive the first gear 12 to move the full stroke on the second rack 24, so that the drilling machine 11 can drive the drill bit vertically downward, which is convenient for the drilling machine 11 to carry out drilling work again. At the same time, when the drill bit of the drilling machine 11 is vertically downward, there is a 5 cm gap between the drill bit and the top end of the electrode rod 31, so as to avoid interference between the drilling machine 11 and the electrode rod 31, and the work is completed.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figure 8 shown, the support wing 2 further includes a protective cover plate 40, a threaded rod 41 and a nut 42. The protective cover plate 40 is fixedly installed on the threaded rod 41. The threaded rod 41 is symmetrically and slidably inserted inside the support wing 2, and the nut 42 is threadedly sleeved at the bottom outer circle of the threaded rod 41.

[0042] When implementing this embodiment, when the device is not in use, the protective cover plate 40 can be slidably sleeved on the top of the guiding mechanism 1 until the threaded rod 41 penetrates through the bottom end of the support wing 2, so that the guiding mechanism 1 can be integrally wrapped and protected. Subsequently, the nut 42 can be screwed and sleeved on the bottom outer circle of the threaded rod 41 until the nut 42 is fastened to the bottom end of the support wing 2, so that the protective cover plate 40 can be restrictedly installed on the top of the guiding mechanism 1, and the guiding mechanism 1 can be protected.
