Description

Technical Field

[0001] This utility model relates to the field of electromagnetic detection technology, and in particular to a magnetometer hanger for electromagnetic detection. Background Technology

[0002] Electromagnetic detection systems are a technology used in geological exploration and resource surveys. The magnetometer mount is one of the key components. The magnetometer mount is mainly used to suspend and stabilize the magnetometer, ensuring that it can accurately measure changes in the geomagnetic field when operating in the air. The magnetometer mount is designed to improve the range of magnetometer probe angle adjustment, facilitate installation and secure fixation, and at the same time, not interfere with the magnetometer and its electromagnetic transmitting and receiving devices.

[0003] According to the description in the patent application CN 208535498 U, "This utility model discloses a magnetometer hanger for a time-domain airborne electromagnetic detection system, comprising a probe box, a counterweight box, a long hanger tube, a perforated tube clamp, a balancing tail fin, and a fixing fixture; the probe box is located at one end of the long hanger tube, the counterweight box is located at the other end of the long hanger tube, and the balancing tail fin and fixing fixture are located at the tail end of the long hanger tube near the probe box end; a magnetometer probe is installed inside the probe box; the perforated tube clamp is fixed to the tube body of the long hanger tube. The probe box includes a probe holder, a rotatable spherical shell, and a probe box outer shell; the probe holder is fixed inside the rotatable spherical shell, and the rotatable spherical shell is located inside the probe box outer shell and can rotate. All materials are glass fiber or engineering plastics."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this invention utilizes a rotatable spherical shell within the probe housing to adjust the angle of the magnetometer probe, ensuring that the angle between the probe's central axis and the Earth's magnetic field remains within a suitable range. This guarantees accurate data measurement. Simultaneously, counterweights within the counterweight box maintain balance at both ends of the long tube of the pylon, ensuring the overall stability of the magnetometer pylon during flight. The balancing tail fin further enhances stability during flight. However, because the long tube of the pylon cannot be extended or retracted, the fixed length may lead to displacement under vibration or impact, affecting the stability of the detection equipment and the accuracy of the detection results. Furthermore, the inability to adjust the height and angle of the pylon significantly limits the flexibility and applicability of the detection equipment. Therefore, an improved magnetometer pylon for electromagnetic detection is needed to address these issues. Utility Model Content

[0006] To overcome the limitations of the magnetometer hanger used in electromagnetic detection, which cannot extend or retract its long tube, the fixed length of the hanger may cause displacement under certain vibrations or impacts, affecting the stability of the detection equipment and the accuracy of the detection results. Since the hanger length cannot be extended or retracted, users cannot adjust the height and angle of the hanger as needed, which greatly limits the flexibility and applicability of the detection equipment.

[0007] The technical solution of this utility model is as follows: a magnetometer hanger for electromagnetic detection includes a fixed outer rod, an air pump housing, and an adjustment assembly. A telescopic inner rod is installed inside the fixed outer rod. A fixed mounting base is fixedly connected to the outside of the telescopic inner rod. A balance tail fin is fixedly connected inside the fixed mounting base and is located outside the telescopic inner rod. A counterweight box is installed on the back of the fixed outer rod. The adjustment assembly is located on the front of the telescopic inner rod. An air pump housing is fixedly connected to the outside of the fixed outer rod. An air pump body is installed inside the air pump housing. A pneumatic push rod is fixedly connected to the front of the air pump body and is fixedly connected to the back of the telescopic inner rod. A sliding indicator rod is fixedly connected to the outside of the telescopic inner rod and is slidably connected inside the fixed outer rod.

[0008] Preferably, the fixed outer rod has a groove at the corresponding position of the pneumatic push rod, and the pneumatic push rod slides inside the groove.

[0009] Preferably, the fixed outer rod has a groove at the corresponding position of the sliding indicator rod, and the sliding indicator rod slides inside the groove.

[0010] Preferably, a fixed connecting seat is fixedly connected to the outside of the fixed mounting base, a limiting mounting seat is fixedly connected to the outside of the fixed outer rod, and a limiting rod is fixedly connected to the front of the limiting mounting seat, with the limiting rod sliding inside the fixed connecting seat.

[0011] Preferably, several fixed connecting seats are provided, and the several fixed connecting seats are evenly fixedly connected to the outside of the fixed mounting seat.

[0012] Preferably, the adjustment assembly includes a probe box base, a protective plate and a probe box shell are fixedly connected to the back of the probe box base, a rotatable spherical shell and a hemispherical shell are provided inside the probe box base, a lower clip and an upper shell clip are provided inside the rotatable spherical shell and the hemispherical shell, and a probe box cover is provided on the top of the probe box base.

[0013] Preferably, the probe box base has grooves at corresponding positions of the rotatable spherical shell and the hemispherical shell, and the rotatable spherical shell and the hemispherical shell rotate inside the grooves.

[0014] The beneficial effects of this utility model are as follows: Compared with the magnetometer hanger of electromagnetic detection, which cannot extend or retract the long tube of the hanger, the air pump body set inside the air pump housing generates air pressure to push the air pressure push rod to slide inside the fixed outer rod. When the fixed outer rod slides, it is limited by the set sliding indicator rod, so that the device can be effectively adjusted in length, ensuring the stability of the detection equipment and the accuracy of the detection results, enhancing the flexibility and applicability of the detection equipment, and thus effectively preventing the inability to extend or retract the long tube of the hanger, and the fixed length of the hanger may cause the hanger to shift under certain vibrations or impacts.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 4This utility model provides an embodiment of a magnetometer hanger for electromagnetic detection, including a fixed outer rod 1, an air pump housing 801, and an adjustment assembly. A telescopic inner rod 2 is disposed inside the fixed outer rod 1, and a fixed mounting base 3 is fixedly connected to the outside of the telescopic inner rod 2. A balance tail fin 4 is fixedly connected inside the fixed mounting base 3 and disposed outside the telescopic inner rod 2. A counterweight box 5 is disposed on the back of the fixed outer rod 1. The adjustment assembly is disposed on the front of the telescopic inner rod 2. The air pump housing 801 is fixedly connected to the outside of the fixed outer rod 1, and an air pump body 802 is disposed inside the air pump housing 801. A pneumatic push rod 803 is fixedly connected to the front of the air pump body 802 and is fixedly connected to the back of the telescopic inner rod 2. A sliding indicator rod 804 is fixedly connected to the outside of the telescopic inner rod 2 and is slidably connected inside the fixed outer rod 1. The length of the device can be adjusted by the fixed outer rod 1 and the telescopic inner rod 2. The seat 3 serves to fix the balancing tail fin 4. The counterweight box 5 provides a load-bearing effect for the device. The balancing tail fin 4 provides balance for the device in flight. The air pump body 802, located inside the air pump housing 801, generates air pressure to push the air pressure push rod 803 to slide inside the fixed outer rod 1. When the fixed outer rod 1 slides, the sliding indicator rod 804 limits its movement, thus limiting the extension and retraction of the inner rod 2. The fixed outer rod 1 has a groove corresponding to the position of the air pressure push rod 803. The air pressure push rod 803 slides inside the groove. The groove inside the fixed outer rod 1 corresponding to the position of the air pressure push rod 803 limits the movement of the air pressure push rod 803. The fixed outer rod 1 also has a groove corresponding to the position of the sliding indicator rod 804. The sliding indicator rod 804 slides inside the groove. The groove inside the fixed outer rod 1 corresponding to the position of the sliding indicator rod 804 makes the extension and retraction of the inner rod 2 more stable when sliding.

[0022] Please see Figure 2 - Figure 3 In this embodiment, a fixed connecting seat 805 is fixedly connected to the outer side of the fixed mounting base 3, and a limiting mounting seat 806 is fixedly connected to the outer side of the fixed outer rod 1. A limiting rod 807 is fixedly connected to the front of the limiting mounting seat 806. The limiting rod 807 slides inside the fixed connecting seat 805. When the telescopic inner rod 2 is telescopic, the limiting rod 807 set on the limiting mounting seat 806 will be limited by the fixed connecting seat 805, making it more stable when telescopic. Several fixed connecting seats 805 are provided, and several fixed connecting seats 805 are evenly fixedly connected to the outer side of the fixed mounting base 3. The several fixed connecting seats 805 make the device more stable when sliding.

[0023] Please see Figure 4In this embodiment, the adjustment assembly includes a probe box base 901. A protective plate 902 and a probe box outer shell 903 are fixedly connected to the back of the probe box base 901. A rotatable spherical shell 904 and a hemispherical shell 905 are disposed inside the probe box base 901. A lower clip 906 and an upper shell support 907 are disposed inside the rotatable spherical shell 904 and the hemispherical shell 905. A probe box cover 908 is disposed on the top of the probe box base 901. By fixing the magnetometer to the hemispherical shell 905 and the rotatable spherical shell 904 inside the probe box cover 908, during adjustment, the lower clip... The support 906 and the upper shell support 907 serve to fix the magnetometer. The magnetometer can be adjusted and changed at multiple angles by rotating the probe box outer shell 903 and the rotatable spherical shell 904. The probe box bottom support 901 has a sliding groove at the corresponding position of the rotatable spherical shell 904 and the hemispherical shell 905. The rotatable spherical shell 904 and the hemispherical shell 905 rotate inside the sliding groove. Through the sliding grooves opened inside the probe box bottom support 901 at the corresponding positions of the rotatable spherical shell 904 and the hemispherical shell 905, the rotatable spherical shell 904 and the hemispherical shell 905 can adjust the magnetometer to the required position.

[0024] During operation, the magnetometer is fixed to the hemispherical shell 905 and rotatable spherical shell 904 inside the probe box cover 908. During adjustment, the lower bracket 906 and upper shell bracket 907 fix the magnetometer. The rotation of the probe box shell 903 and rotatable spherical shell 904 allows the magnetometer to be adjusted and changed at multiple angles. When adjusting the length extension, the balancing tail fin 4 provides balance for the device in flight. The air pump body 802 inside the air pump shell 801 generates air pressure to push the air pressure push rod 803 to slide inside the fixed outer rod 1. When the fixed outer rod 1 slides, the sliding indicator rod 804 limits it, so that the extension and retraction of the inner rod 2 can be limited. When the device is in flight, the fixed mounting base 3 fixes the balancing tail fin 4. The counterweight box 5 provides a load-bearing effect for the device. The balancing tail fin 4 provides balance for the device in flight.

[0025] Through the above steps, the air pump body 802, located inside the air pump housing 801, generates air pressure to push the air pressure push rod 803 to slide inside the fixed outer rod 1. When the fixed outer rod 1 slides, it is limited by the sliding indicator rod 804, so that the telescopic inner rod 2 can be limited during telescopic movement. This solves the problem that the magnetometer hanger used for electromagnetic detection cannot extend or retract its long tube. The fixed length of the hanger may cause displacement of the hanger under certain vibrations or impacts, affecting the stability of the detection equipment and the accuracy of the detection results. Since the length of the hanger cannot be extended or retracted, the user cannot adjust the height and angle of the hanger as needed, which greatly limits the flexibility and applicability of the detection equipment.
