[0033] like Figures 1-2 As shown, a spherical antenna with grooves is composed of several circular coils 1 wound together to form a sphere, and each of the circular coils 1 has several concave grooves 2 on which copper wire is wound.
[0034] Working principle:
[0035] like Figure 3 As shown, the antenna utilizes the principle of electromagnetic induction to detect the trajectory and depth of underground buried rays. First, a signal is injected into the buried ray via a dedicated transmitter, causing it to emit electromagnetic waves. Then, two spherical antennas positioned at different heights from the ray receive the electromagnetic signals from the underground pipeline at their respective locations. Finally, by further processing the received signals, the location and depth of the ray can be deduced.
[0036] Example 2
[0037] like Figures 4-7 As shown, the lightning protection testing instrument using a spherical antenna includes an upper structure 3, a lower antenna structure 6, and an intermediate connecting structure; the upper structure 3 and the lower antenna structure 6 are connected to form a whole through the intermediate connecting structure.
[0038] The upper structure 3 includes a data acquisition end 31 and an upper spherical antenna 32; the top of the data acquisition end 31 is equipped with a display screen 34, a hand handle 33, and a plastic box 35 for accommodating the display screen 34; the upper spherical antenna 32 is connected to the data acquisition end 31 through a cylindrical component;
[0039] The lower antenna structure 6 includes one lower spherical antenna and two hemispherical antennas;
[0040] The intermediate connecting structure consists of a foldable folding disc 4 and a knob 5 for fixing the folding disc 4.
[0041] The folding disk 4 is composed of a left cover 43, a right cover 44, a left cover 41 of the upper fixing seat 46, a right cover 42 of the lower fixing seat 45;
[0042] The left cover 41 of the upper fixed seat of the turntable, the left cover 42 of the lower fixed seat of the turntable, the left cover 43 of the turntable, the right cover 44 of the turntable, the right cover 45 of the lower fixed seat of the turntable, and the right cover 46 of the upper fixed seat of the turntable are placed together in sequence;
[0043] The left cover 41 of the upper fixed seat, the right cover 46 of the upper fixed seat, the left cover 42 of the lower fixed seat and the right cover 45 of the lower fixed seat are fixed together with the left cover 43 of the upper fixed seat, the right cover 44 of the upper fixed seat and the knob 5 through screws; the left cover 42 of the lower fixed seat, the right cover 45 of the lower fixed seat and the left cover 43 of the upper fixed seat, the right cover 44 of the upper fixed seat leave a space for the rotation of the upper fixed seat; the left cover 42 of the lower fixed seat and the right cover 45 of the lower fixed seat leave a space for the rotation of the knob 5.
[0044] Working principle:
[0045] In order to ensure that the folding part remains stable during use and prevent accidental unfolding or loosening during use, the device is designed with a knob locking mechanism, as shown in Figures 8-10 .
[0046] Knob locking function: the folding disc 4 of the device is connected with the knob 5. Each folding point position is equipped with a knob 5 and a folding disc 4. When the device is folded to a certain state, the user can rotate the knob 5, and the locking mechanism inside the knob 5 will be activated to generate enough friction or mechanical force to firmly fix the folding disc 4 at the predetermined position. As shown in Figure 11 .
[0047] Locking principle: the knob 5 drives the built-in locking element to be connected with the folding disc 4 by rotating, forming a stable connection. When rotating the knob 5, the internal buckle tightly matches to ensure that the folding disc 4 cannot be accidentally loosened or shifted. In this way, when the device is unfolded for use, the folding disc 4 will be firmly locked to ensure the stability of the structure. When the knob 5 is locked, the device cannot be folded.
[0048] Unlocking function: when the device is folded, the user only needs to rotate the knob 5 counterclockwise to release the fixing of the locking device, allowing the folding part to loosen and return to the folded state. (As shown in Figures 12-13 .
[0049] The utility model discloses a circular antenna with a groove, which can quickly calculate the depth and trend of the ground net in combination with an external embedded hardware module, and the depth and trend can be directly observed by naked eyes.
[0050] The folding structure improves the portability of the device.
[0051] The knob 5 is locked at the folding position to prevent the two parts of the instrument from loosening after unfolding or folding.
[0052] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and equivalent technologies, the utility model also intends to include these modifications and variations.
