Abstract
Description
Technical Field
[0001] This application relates to the technical field of exploration equipment, and particularly relates to a magnetometer for prospecting measurement. Background Art
[0002] Magnetometers are widely used in prospecting. They mainly study geological structures and their distribution patterns by measuring the intensity and direction of the geomagnetic field, and search for various mineral resources. Magnetometers can be divided into two categories: absolute magnetometers and relative magnetometers. Their main uses are to collect magnetic anomaly data and measure rock magnetic parameters.
[0003] The most commonly used high-precision prospecting instrument in prospecting is the proton magnetometer, which is mainly developed based on the principle of the free precession of hydrogen proton magnetic moments in the geomagnetic field. It has the advantages of high sensitivity and wide range, and is suitable for global measurements. This instrument performs well in detecting iron ore, non-ferrous metal deposits, etc., and can also perform gradient measurements.
[0004] Existing proton magnetometers include a magnetometer main unit, a probe, a probe rod, accessory parts, and an instrument packing box. When in use, technicians first assemble the probe rod, then install the probe on the probe rod, and then electrically connect the probe and the magnetometer main unit with a special data cable. Next, the measurement operation can be started. The general process is as follows: First, place the magnetometer main unit at the working location, install the battery, turn on the switch, and then the measurement personnel hold the probe rod with the probe and insert it into the pre-marked measurement point to start the measurement work. During the measurement, due to the limited length of the connection line between the magnetometer main unit and the probe, when the measurement personnel move the probe rod and the probe, they often move the magnetometer main unit together. When reaching the measurement point, because the probe rod needs to be inserted vertically at the measurement point, the measurement personnel often place the relatively heavy magnetometer main body on the ground first for the convenience of inserting the probe rod. After inserting the probe rod, they then squat in front of the magnetometer main body to perform corresponding operations. Such operations are not only troublesome but also the measurement personnel need to squat frequently and are easily fatigued. If the number of personnel during the measurement is increased, the labor cost will be correspondingly increased. Content of the Utility Model
[0005] This application provides a magnetometer for prospecting measurement, which is convenient for measurement personnel to perform prospecting operations outdoors.
[0006] The above object of this application is achieved through the following technical solutions:
[0007] An outer protective shell is installed outside the magnetometer main unit. The outer protective shell is provided with a protective cover. One end in the width direction of the protective cover is hinged to the outer protective shell, and the other end in the width direction of the protective cover is connected to the outer protective shell through a buckle assembly;
[0008] One opposite side exterior part in the length direction of the outer protective case is respectively provided with a strap, and two ends of the strap are respectively connected with the outer side wall of the corresponding side of the outer protective case through a set of detachable connection components;
[0009] When the magnetometer host is located at the front side of the surveyor's body, the length of the strap satisfies that after it is hung on the surveyor's shoulder, the magnetometer host can hover at a position below the surveyor's chest;
[0010] A handle is fixedly arranged at the middle position of the top of the outer protective case.
[0011] Furthermore, a Japanese character buckle for adjusting its length is threaded on the strap.
[0012] Furthermore, the connection component includes a hook and a buckle that are buckled together. The hook is fixedly installed at one end of the strap, and the buckle is movably connected with the outer side wall of the outer protective case through a binding strap.
[0013] Furthermore, a plurality of clamping components are arranged on the back side of the outer protective case along the vertical direction, and each clamping component can place one section of the probe rod.
[0014] Furthermore, the clamping component includes two pipe clamps arranged along the length direction of the outer protective case, and the two pipe clamps are arranged at intervals along the length direction of the outer protective case.
[0015] Furthermore, the pipe clamp includes a fixed clamping plate and a movable clamping plate. The fixed clamping plate is fixedly installed on the outer protective case. One end of the movable clamping plate and the fixed clamping plate in the height direction of the outer protective case are movably hinged together through a first pin shaft, and the other end of the movable clamping plate and the fixed clamping plate in the height direction of the outer protective case are detachably connected together.
[0016] Furthermore, a first notch is arranged at the middle position of one end of the fixed clamping plate far away from the first pin shaft, and a second notch is arranged at the position corresponding to the first notch on the movable clamping plate; a second pin shaft is arranged through the first notch along the length direction of the outer protective case, a rotating ring is movably sleeved on the second pin shaft, a butterfly bolt is fixedly connected to the rotating ring, and the width of the nut of the butterfly bolt is greater than the width of the second notch.
[0017] Furthermore, a storage bag is respectively installed on one opposite side in the length direction of the outer protective case, and the position of the storage bag on the outer side wall of the outer protective case is lower than the buckle on the corresponding side.
[0018] In summary, the present application includes at least the following beneficial technical effects:
[0019] When the surveyor needs to conduct prospecting operations in a designated area, they can first hold the main body of the magnetometer in front of their chest, and then hang the two straps along the length of the outer protective case of the main body of the magnetometer on their shoulders respectively. At this time, after letting go, the main body of the magnetometer can hover below the chest of the surveyor. Since the weight of the entire magnetometer main body is borne by the shoulders of the surveyor, it is more labor-saving and comfortable compared to holding the main body of the magnetometer by hand. Moreover, in this way, when the surveyor is prospecting, they can also free up both hands, which is convenient for manipulating the exploration rod to align with the measurement point. When the exploration rod is aligned with the measurement point, the surveyor does not need to bend down, but only needs to lower their head to perform corresponding operations on the main body of the magnetometer inside the outer protective case. It is significantly more convenient to use compared to the prior art, and there will be no fatigue caused by frequent squatting and standing up. When it is necessary to go to other areas for prospecting operations, the surveyor can place the main body of the dynamometer behind them and hang the two straps on their shoulders, which is also very convenient to carry.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts also belong to the scope of protection of this application.
[0026] As Figure 1 and Figure 2 shown, a magnetometer for prospecting measurement disclosed in this application includes a magnetometer main body 1 and a probe rod 2. An outer protective shell 3 is installed on the outside of the magnetometer main body 1. The outer protective shell 3 is provided with a protective cover 4. One end of the protective cover 4 in the width direction is hinged to the outer protective shell 3, and the other end of the protective cover 4 in the width direction is connected to the outer protective shell 3 through a buckle assembly 5; on the outer sides of a pair of opposite sides in the length direction of the outer protective shell 3, a shoulder strap 6 is respectively provided. Both ends of the shoulder strap 6 are respectively connected to the outer side wall of the corresponding side of the outer protective shell 3 through a set of detachable connection components 7; when the magnetometer main body 1 is located in front of the body of the measuring person, the length of the shoulder strap 6 is such that after it is hung on the shoulder of the measuring person, the magnetometer main body 1 can hover at a position below the chest of the measuring person; a handle 8 is fixedly provided at the middle position of the top of the outer protective shell 3.
[0027] In the above embodiments, the outer protective shell 3 provided on the outside of the magnetometer main body 1 of this application cooperates with the protective cover 4 to effectively protect the magnetometer main body 1 and prevent the magnetometer main body 1 from being damaged by bumps during use. One end of the protective cover 4 is hinged to the outer protective shell 3, and the other opposite end of the protective cover 4 can be connected to the outer protective shell 3 through the buckle assembly 5, which is convenient for the measuring person to open the protective cover 4 at any time according to needs during use to expose the magnetometer main body 1 in the outer protective shell 3, or after using the magnetometer main body 1, buckle the protective cover 4 on the outer protective shell 3 to store and protect the magnetometer main body 1.
[0028] When the existing magnetometer main body 1 for prospecting is in use, it is mostly carried by the measuring person to the outdoor work location by hand, and then the probe rod 2 equipped with a probe is vertically inserted into one of the points to be measured. After the probe rod 2 is inserted, the measuring person bends down to perform corresponding operations on the magnetometer main body 1. When it is necessary to measure the next point, the measuring person needs to pick up the magnetometer main body 1 again, pull out the probe rod 2, and move to the next work location to repeat the above operations. In this way, not only is it very troublesome for the measuring person to operate, but also the measuring person needs to frequently bend down and pick up and put down the magnetometer main body 1 with both hands when measuring and moving the equipment, which is very likely to increase the fatigue of the measuring person during work and affect the measuring efficiency.
[0029] On opposite sides in the length direction of the outer protective shell 3 of the present application, a strap 6 is respectively installed, and the length of the strap 6 is such that when it is hung on the shoulders of the surveyor, the outer protective shell 3 equipped with the magnetometer main unit 1 hovers in the area below the chest of the surveyor, so that the outer protective shell 3 equipped with the magnetometer main unit 1 becomes a structure similar to a backpack. When the surveyor moves over a long distance, the magnetometer main unit 1 can be carried on the back or chest through the two straps 6, and the weight of the magnetometer main unit 1 is borne by the weight of the own shoulders. Compared with holding the magnetometer main unit 1 by hand, it is not only labor-saving but also comfortable. When carrying out the measurement work in the marked measurement point area at the measurement site, the surveyor can place the outer protective shell 3 equipped with the magnetometer main unit 1 in front of the chest, and the buckle assembly 5 on the protective cover 4 and the outer protective shell 3 also faces the front of the surveyor's chest. Then, the two straps 6 are slung on the own shoulders. Next, the probe rod 2 equipped with the probe can be inserted into one of the points to be measured. After inserting the probe rod 2, open the protective cover 4, and the relevant operations for measuring the magnetometer main unit 1 can be directly carried out in the outer protective shell 3 without bending down. After recording the data, directly pull out the probe rod 2 and move to the next point to be measured.
[0030] Compared with the prior art, the magnetometer of the present application saves the trouble of the surveyor frequently getting up and squatting during use, is simple and convenient to operate, and the weight of the magnetometer main unit 1 can be borne by the shoulders with stronger load-bearing capacity through the strap 6, which is significantly more comfortable and labor-saving compared with the way of holding by hand. In addition, during measurement, a single surveyor can efficiently complete the measurement work, effectively saving labor costs.
[0031] Further, as Figure 1 and Figure 2 shown, a Japanese character buckle 9 for adjusting its length is threaded on the strap 6.
[0032] In the above embodiments, the strap 6 of the present application is arranged in the above manner. During use, users of different heights can adjust the length of the strap 6 through the Japanese character buckle 9 so that the outer protective shell 3 equipped with the magnetometer main unit 1 hovers at a suitable height for themselves, effectively improving the applicability of the magnetometer of the present application.
[0033] Further, as Figure 3 shown, the connecting component 7 includes a hook 71 and a buckle 72 buckled together. The hook 71 is fixedly installed at one end of the strap 6, and the buckle 72 is movably connected to the outer side wall of the outer protective shell 3 through a binding strap 73.
[0034] In the above embodiments, hooks 71 are connected to both ends of the two straps 6 of the present application, and two buckle rings 72 are installed on opposite side walls in the length direction of the outer protective shell 3. During use, the hooks 71 of the straps 6 are hung on the two buckle rings 72 in the corresponding area of the outer protective shell 3, thus completing the assembly of the straps 6 and the outer protective shell 3. When the strap 6 is worn and needs to be replaced, the surveyor can simply loosen the hook 71 of the damaged strap 6 from the corresponding buckle ring 72, which is flexible and convenient to operate.
[0035] Further, as Figure 2 shown, a plurality of clamping components 10 are provided on the back side of the outer protective shell 3 in the vertical direction, and each clamping component 10 can hold one section of the probe rod 2.
[0036] In the above embodiments, in actual production, since the probe rod 2 is relatively long, for convenient storage and transportation, the probe rod 2 is usually composed of a plurality of sub-rods that can be threadedly connected together. During use, these sub-rods are connected end to end in sequence, and when storing and transporting, these sub-rods can be disassembled one by one. However, usually these probe rods 2 need to be packaged in a separate packaging bag, which is not convenient to carry. The plurality of clamping components 10 provided on the back side of the outer protective shell 3 of the present application can hold these sub-probe rods 2 of the probe rod 2 one by one. In this way, when storing these probe rods 2, the trouble of storing these probe rods 2 in a separate backpack can be saved. When traveling long distances, the surveyor only needs to carry the outer protective shell 3 equipped with the magnetometer main unit 1 on the back, which will be more convenient.
[0037] Further, as Figure 2 shown, the clamping component 10 includes two pipe clamps 101 arranged along the length direction of the outer protective shell 3, and the two pipe clamps 101 are arranged at intervals along the length direction of the outer protective shell 3.
[0038] In the above embodiments, when one section of the probe rod 2 (one of the sub-rods of the probe rod 2) is placed in the two pipe clamps 101 with a certain interval, the two pipe clamps 101 provide uniform supporting force for this section of the probe rod 2, so that it is stably fixed on the outer protective shell 3 and prevents it from shaking during movement.
[0039] Further, as Figure 2 and Figure 3 shown, the pipe clamp 101 includes a fixed clamping plate 1011 and a movable clamping plate 1012. The fixed clamping plate 1011 is fixedly installed on the outer protective shell 3. The movable clamping plate 1012 and the fixed clamping plate 1011 are movably hinged together at the same end in the height direction of the outer protective shell 3 through a first pin shaft 1013, and the other end of the movable clamping plate 1012 and the fixed clamping plate 1011 in the height direction of the outer protective shell 3 are detachably connected together.
[0040] In the above embodiments, the movable clamping plate 1012 and the fixed clamping plate 1011 of the present application are both arc-shaped structures. In this way, when they cooperate to clamp the probe rod 2, the contact area with the surface of the probe rod 2 can be increased, so that the probe rod 2 can be clamped more stably. One end of the movable clamping plate 1012 is hinged to the fixed clamping plate 1011 through the first pin shaft 1013. A detachable connection can be achieved between the other opposite end of the movable clamping plate 1012 and the fixed clamping plate 1011 through existing connecting parts such as bolts and nuts or binding ropes when connecting. Taking bolts and nuts as an example, after one section of the probe rod 2 is placed between the movable clamping plate 1012 and the fixed clamping plate 1011, the probe rod 2 can be firmly fixed by screwing the bolt and the nut matching with the bolt. When the probe rod 2 needs to be removed, the surveyor only needs to loosen the bolt and the corresponding nut, so that the installation and removal of the probe rod 2 on the outer protective shell 3 are very convenient.
[0041] Further, as Figure 3 shown, a first notch 11 is provided at the middle position of the end of the fixed clamping plate 1011 far from the first pin shaft 1013, and a second notch 12 is provided at the position of the movable clamping plate 1012 corresponding to the first notch 11; a second pin shaft 13 is provided through the first notch 11 along the length direction of the outer protective shell 3, a rotating ring 14 is movably sleeved on the second pin shaft 13, a butterfly bolt 15 is fixedly connected to the rotating ring 14, and the width of the nut of the butterfly bolt 15 is greater than the width of the second notch 12.
[0042] In the above embodiments, one end of the threaded section of the butterfly bolt 15 is movably installed in the first notch 11 of the fixed clamping plate 1011 through the rotating ring 14 and the second pin shaft 13. After one sub-rod of the probe rod 2 is placed between the movable clamping plate 1012 and the fixed clamping plate 1011, the surveyor closes the movable clamping plate 1012, swings the butterfly bolt 15 on the fixed clamping plate 1011 to rotate it into the second notch 12 of the movable clamping plate 1012. At this time, the nut on the butterfly bolt 15 is located on the side of the second notch 12 away from the first notch 11. The surveyor can tighten the nut of the butterfly bolt 15 to fix the sub-rod of the probe rod 2 by using the movable clamping plate 1012 and the fixed clamping plate 1011. Subsequently, when assembling the probe rod 2, the surveyor loosens the nut on the butterfly bolt 15 and rotates the butterfly bolt 15 to make it leave the second notch 12 on the movable clamping plate 1012. At this time, the restriction of the butterfly bolt 15 on the movable clamping plate 1012 can be released, and the movable clamping plate 1012 can be freely opened to take out the corresponding sub-rod of the probe rod 2. In this application, the connecting member connecting the fixed clamping plate 1011 and the movable clamping plate 1012 is preferably the butterfly bolt 15 because the nut of the butterfly bolt 15 is in the shape of a ram's horn, which is convenient for the surveyor to exert force when tightening. In addition, the butterfly bolt 15 is movably connected to the fixed clamping plate 1011 through the rotating ring 14 and the second pin shaft 13, so that the butterfly bolt 15 can always be connected to the fixed clamping plate 1011, which is convenient for the surveyor to take the butterfly bolt 15 at any time when installing and disassembling the movable clamping plate 1012, and can also prevent the butterfly bolt 15 from being lost.
[0043] Further, as Figure 1 and Figure 2 shown, a storage bag 16 is respectively installed on a pair of opposite sides in the length direction of the outer protective shell 3, and the position of the storage bag 16 on the outer side wall of the outer protective shell 3 is lower than the corresponding buckle 72.
[0044] In the above embodiments, the storage bag 16 provided on the outer protective shell 3 can be used to store the probe, the connecting wire and some other accessory parts. In this way, during the journey, the surveyor can store most of the sub-devices of the magnetometer through the outer protective shell 3, improving the convenience during use. The storage bag 16 is arranged below the corresponding buckle 72 on the outer protective shell 3, which can prevent the strap 6 from squeezing the storage bag 16 during use.
[0045] The implementation principle of this embodiment is as follows: when the surveyor needs to perform prospecting operations in a designated outdoor area, the accessories such as the probe rod 2 and the probe on the magnetometer main unit 1 can be taken off first, then assembled, and then the outer protective shell 3 containing the magnetometer main unit 1 is held in front of the chest. Then, the two straps 6 are respectively hung on the two shoulders. At this time, after letting go, the magnetometer main unit 1 can hover at a suitable position in front of the surveyor's chest, and then the formal detection work can be started.
[0046] The surveyor holds the assembled sounding rod 2 in one hand and inserts its tip into one of the pre-marked points to be measured. After insertion, open the protective cover 4 on the outer protective shell 3, and operate and record the detection data on the magnetometer main unit 1 inside the outer protective shell 3 with both hands. Then, pull out the sounding rod 2 and move it to the next point to be measured and repeat the above operation. Compared with the prior art, it is significantly more convenient and efficient to use, and there will be no fatigue caused by frequent squatting and standing up.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
