[0003] In magnetotelluric (MT) operations, the probe and the connecting cable between the probe and the acquisition instrument are susceptible to external wind noise, which can cause them to sway and cut magnetic field lines, interfering with the acquired data. Existing technologies mostly focus on preventing probe swaying to reduce wind noise, but there are few dedicated protective devices for the cable harness.

Figures 1-7 As shown, the device includes a probe windproof barrel, a wire harness windproof tube, and a wire harness clip. The probe windproof barrel includes a probe windproof barrel body 1. A wedge-shaped ring 10 is provided at the bottom of the probe windproof barrel body 1. When in use, the wedge-shaped ring 10 is inserted into the soil to prevent air convection from flowing into the device through the gaps and interfering with the probe.
[0027] A rubber bottom ring 5 is provided on the outer side of the wedge ring 10. The rubber bottom ring 5 is elastic and can fit tightly with the ground to reduce gaps. A long ground spike 4 is provided at the lower end of the rubber bottom ring 5. When in use, the long ground spike 4 is inserted into the ground to fix the probe windproof barrel.
[0028] An extension fixing block 3 is also provided on the outer bottom of the probe windproof casing 1. A long ground spike 4 is provided at the lower end of the extension fixing block 3. The extension fixing block 3 can further fix the probe windproof casing to prevent it from loosening. At the same time, in order to reduce wind resistance, the probe windproof casing 1 is shaped like a truncated cone with a spherical crown.
[0029] The wire harness windproof tube body 2 has fastening holes 9 and fastening pins 11 at both ends. An external connecting pipe 6 is provided on the outer side of the bottom of the probe windproof tube body 1. The external connecting pipe 6 is used to connect the wire harness windproof tube. The opening of the external connecting pipe 6 is also provided with fastening holes 9, which can be assembled with the fastening pins 11 on the wire harness windproof tube body 2 during use.
[0030] The wire harness windproof tube includes a wire harness windproof tube body 2. A wedge-shaped strip 12 is provided at the bottom of the wire harness windproof tube body 2. A rubber strip 7 is provided on the outside of the wedge-shaped strip 12. A short ground spike 8 is provided at the lower end of the rubber strip 7.

The wedge-shaped strip 12 is inserted into the soil to prevent air convection from flowing into the gaps of the device and interfering with the wire harness.
[0031] To reduce wind resistance, the cross-sectional shape of the wire harness windproof tube body 2 is arc-shaped. The wire harness windproof tube body 2 is equipped with a wire harness clip, which includes a retaining ring 13 and a ground pin 14. The retaining ring 13 is used to hold the wire harness, and the ground pin 14 is used to fix the wire harness and the retaining ring 13 to the ground.
[0032] Because the conductivity of metal and carbon fiber materials can affect the detection of the probe, in this embodiment, the probe windproof barrel body 1, the wire harness windproof tube body 2, the extension fixing block 3, the long ground spike 4, the short ground spike 8, the external connecting pipe 6, the wedge ring 10, the wedge strip 12, the retaining ring 13, and the ground pin 14 are all made of engineering plastics.
[0033] The wind noise reduction device for a magnetotelluric magnetic track receiver described in this embodiment operates as follows:
[0034] First, the detection point is selected and pre-treated. After clearing away surface debris, the magnetotelluric probe is buried in the soil at the designated depth. Then, the wiring harness connecting the probe and the detector is laid. During the wiring process, a wiring harness clip is used at intervals to secure the wiring harness with a clip ring 13. Then, the ground pin 14 at the bottom of the clip ring 13 is vertically inserted into the ground to achieve segmented fixation of the wiring harness on the ground.
[0035] Install the probe windproof casing. Insert the wedge-shaped ring 10 and the long ground spike 4 at the bottom of the probe windproof casing body 1 into the soil, ensuring the rubber bottom ring 5 is tightly fitted to the ground. Simultaneously press the extension fixing block 3, allowing the long ground spike 4 at its lower end to insert into the ground at the same time. Then, connect the wire harness windproof tube from the external connecting pipe 6 on the outer side of the bottom of the probe windproof casing body 1. Align and engage the fastening pin 11 at one end of the wire harness windproof tube body 2 with the fastening hole 9 at the opening of the external connecting pipe 6, completing the connection of the first section of the windproof tube.
[0036] Connect the windproof tubes of the wire harness segment by segment according to the above connection method. During the connection process, ensure that the wedge strip 12 at the bottom of each windproof tube is inserted into the soil, the rubber strip 7 is in contact with the ground, and the short ground spike 8 is inserted into the soil for fixation, until all the laid wire harnesses are completely covered by the windproof tubes.
[0037] Therefore, this utility model adopts the above-mentioned anti-wind noise device for a magnetotelluric receiver. The wire harness is fixed by a wire harness clip, a windproof barrel is set on the outside of the probe, and a windproof tube is set on the outside of the wire harness. The device is fixed by long and short ground spikes. The wedge-shaped structure next to the ground spikes penetrates into the soil to block wind intrusion. The rubber strip enhances the fit between the device and the ground. The windproof barrel of the probe and the windproof tube of the wire harness are connected and assembled by fastening holes and fastening pins to ensure full protection. This achieves simultaneous protection of the probe and the wire harness, effectively reducing the impact of wind noise.
