Description

Technical Field

[0001] The invention belongs to the technical field of gravity measurement equipment, and in particular to a microgravity measurement device and method. Background Art

[0002] Microgravity measurement refers to the measurement accuracy and the gravity effect caused by the object of measurement and exploration are measured in micro-gamma values. Since the micro-measurement method has low requirements for the abnormal field strength and has the advantages of being fast and economical, the microgravity measurement method is widely used in the fields of mineral exploration and prospecting.

[0003] When using a microgravity measurement device to search for ore bodies, the staff will move the microgravity measurement device to the measurement point after planning the measurement point, and conduct multiple measurements at the measurement point. During the measurement process, in order to avoid the influence of differences in the field environment on the accuracy of gravity detection, it is usually necessary to first set up the instrument chassis at the observation point, and then take out the gravity meter, place it on the chassis, and perform multiple adjustments to the chassis, such as horizontal adjustment and accuracy adjustment. At the same time, since the microgravity measurement device is a precision instrument, during the transportation and use of the microgravity measurement device, it is necessary to follow a number of precautions, such as handling with care, strictly prohibiting collisions, and keeping the instrument horizontal, which makes the transportation and use of the microgravity measurement device more troublesome.

[0004] In order to enhance the convenience of transportation and use of gravity measuring instruments in the related art, a bracket that is easy to adjust and adjust is usually used to store and support the gravity measuring instruments. For example, Chinese patent application number 2016211288248 discloses a gravimeter, which can reduce the impact of vibration on the gravimeter through an inverted L-shaped rod and a shock absorber. At the same time, during transportation, the impact on the gravimeter can be less than that of using foam sponge pads, soft pads, etc. However, it is found in the actual transportation process that due to the lack of restriction on the shaking range of the gravimeter in this scheme, on the one hand, when transported by vehicle, the gravimeter is easily affected by inertial force and produces a large range of movement, increasing the risk of the gravimeter being bumped or tipped over. On the other hand, the gravimeter deflects too much during the shaking process, causing its internal structure to shake, increasing the probability of failure of the gravimeter.

[0042] Embodiment 1

[0043] Refer to the instruction manual Figure 1-6 The microgravity measuring device of the present invention comprises a gravimeter 1 and a storage box 11 for storing the gravimeter 1, wherein a cushioning cotton sheet is filled between the gravimeter 1 and the storage box 11;

[0045] A base 2, wherein the base 2 is a plate-shaped structure, and the storage box 11 is located above the base 2;

[0046] A support frame 21, wherein the support frame 21 is mounted on the base 2, and a connecting shaft 22 is mounted on one end of the support frame 21 away from the base 2;

[0047] Buffer spring 23, a buffer groove 24 is provided on the storage box 11, the connecting shaft 22 extends into the buffer groove 24, and buffer springs 23 are fixedly installed at both upper and lower ends of the connecting shaft 22, and the buffer spring 23 elastically connects the storage box 11 and the connecting shaft 22;

[0048] A limit spring 25, wherein the limit spring 25 is fixedly mounted at the bottom of the storage box 11, and the limit spring 25 is connected to the support frame 21;

[0049] The horizontal adjustment component is installed on the support frame 21, and the horizontal adjustment component is used to maintain the horizontal placement of the storage box 11;

[0050] The horizontal adjustment assembly includes an adjustment rail 26, which is fixedly mounted on the support frame 21. The adjustment rail 26 is designed to be arc-shaped, and the adjustment rail 26 is designed to be coaxial with the connecting shaft 22.

[0051] A slow-release block 27 is slidably installed in the adjusting rail 26, the slow-release block 27 is frictionally connected with the adjusting rail 26, and the limit spring 25 extends and is fixed on the slow-release block 27;

[0052] The adjustment rail 26 is fixedly connected to the support frame 21 at a 90-degree angle. The support frame 21 is rotatably mounted on the base 2. A gravity block 28 is fixedly mounted on one end of the adjustment rail 26.

[0053] An annular groove 3 is formed on the base 2 , and an extension rod 31 is fixedly mounted on the support frame 21 . The extension rod 31 extends into the annular groove 3 to support the support frame 21 .

[0054] When gravity measurement is used to detect a mining area, it is necessary to use transportation equipment to carry the gravimeter 1 to transfer positions between multiple measurement points. As a precision instrument, the gravimeter 1 is subject to vibration and deflection during transportation, which will increase the probability of failure of the gravimeter 1. In order to reduce the impact of the transportation process on the gravimeter 1, the present invention provides a shock-absorbing component and a horizontal leveling component, which, on the one hand, reduces the impact of vibration on the gravimeter 1, and on the other hand, limits the deflection angle of the gravimeter 1, thereby reducing the probability of failure of the gravimeter 1.

[0055] Specifically, before gravity detection, the gravimeter 1 is first placed inside the storage box 11, and then the buffer cotton sheet is filled in the gap between the storage box 11 and the gravimeter 1, and then the entire device is placed on the transportation equipment. At this time, the gravity of the gravimeter 1 and the storage box 11 acts on the connecting shaft 22 through the buffer spring 23, and then is transmitted to the support frame 21 and the base 2 to achieve elastic support for the storage box 11. During the movement of the transportation equipment, when the transportation equipment vibrates due to factors such as uneven ground, the device vibrates under the action of inertia, and the vibration is transmitted to the base 2, and then transmitted from the base 2 to the support frame 21 and the connecting shaft 22. Since the connecting shaft 22 is connected to the storage box 11 through the buffer spring 23, when the vibration force is transmitted to the storage box 11 through the buffer spring 23, the buffer spring 23 is deformed by the force, thereby offsetting and consuming the force, resulting in a low efficiency of transmitting the vibration to the storage box 11, thereby maintaining the stability of the storage box 11 and the gravimeter 1 inside. When the storage box 11 or the transportation equipment is subjected to the inertial force in the horizontal direction, the storage box 11 rotates around the connecting shaft 22 under the action of the inertial force. When the storage box 11 is deflected, it pulls the limit spring 25 and the release block 27. The release block 27 slides in the inner cavity of the adjustment rail 26. The release block 27 is frictionally connected to the adjustment rail 26, so when the release block 27 slides, the friction force hinders the movement of the release block 27, and then cooperates with the limit spring 25 to buffer the deflection of the storage box 11, so that the deflection angle of the storage box 11 is reduced under the action of inertia, so that the overall stability of the device on the transportation equipment is strong, and the influence of vibration and inertia on the gravimeter 1 is reduced. The support frame 21 is rotatably connected to the base 2, and an extension rod 31 and an annular groove 3 are provided. When in use, when the direction of the force acting on the storage box 11 is different from the direction of the adjustment rail 26, the limit spring 25 pulls the release block 27 and The adjusting rail 26 is pulled, so that the supporting frame 21, the adjusting rail 26 and the storage box 11 rotate on the base 2, causing the adjusting rail 26 to gradually align with the direction of the inertial force exerted on the release box, thereby facilitating the deflection of the storage box 11 and reducing the impact exerted on the storage box 11. At the same time, the setting of the gravity block 28 causes the adjusting rail 26 and the supporting frame 21 to rotate on the base 2 when there is a deviation between the base 2 and the horizontal plane, so that the adjusting rail 26 is aligned with the deflection direction of the base 2. Under the action of gravity, the storage box 11 pulls the limit spring 25 and the release block 27, and finally makes the bottom surface of the storage box 11 flush with the horizontal plane, thereby keeping the gravimeter 1 placed vertically.

[0056] The present invention provides a shock-absorbing component, elastically supports the storage box 11, and cooperates with the deflection of the storage box 11 to effectively buffer the inertial force in the vertical and horizontal directions, thereby reducing the vibration of the storage box 11. At the same time, during transportation, the existence of structures such as the adjustment rail 26 and the connecting shaft 22 allows the storage box 11 to adjust its position under the action of gravity, so that the gravimeter 1 can always remain vertical after being stabilized, thereby reducing the probability of failure of the gravimeter 1.

[0057] Embodiment 2

[0058] This embodiment is improved on the basis of the first embodiment. Figure 1-6 A limiting mechanism is installed in the adjusting rail 26, and the limiting mechanism is used to limit the sliding range of the slow-release block 27. The limiting mechanism includes:

[0059] The limiting block 4 is provided with a limiting groove 41 on the inner wall of the adjusting rail 26, and the limiting block 4 is installed in the limiting groove 41. The end of the limiting block 4 away from the limiting groove 41 is located on the moving path of the slow-release block 27;

[0060] The limiting mechanism further includes a gravity slide plate 42. A moving groove 43 is provided on the adjusting rail 26. The gravity slide plate 42 is slidably installed in the moving groove 43. The moving groove 43 and the limiting groove 41 are both designed to be conductive.

[0061] Magnetic sheets 44, the limiting grooves 41 are symmetrically and evenly distributed on both sides of the inner wall of the adjustment rail 26, and the limiting blocks 4 are fixedly installed with magnetic sheets 44 on one side close to each other, and the corresponding two magnetic sheets 44 repel each other;

[0062] Deflection protrusions 45, the two ends of the gravity slide plate 42 are fixedly mounted with deflection protrusions 45, the limit blocks 4 are extended into the moving grooves 43 through the limit grooves 41, and the limit blocks 4 are located on the moving path of the deflection protrusions 45;

[0063] During transportation, in order to limit the deflection angle of the storage box 11, so that the deflection angle of the gravimeter 1 in the storage box 11 is maintained within a certain range compared to the horizontal plane, a limiting mechanism is set to hinder the movement of the release block 27. Specifically, when the device is stably placed, the gravity slide 42 slides in the moving groove 43 under the action of gravity. During the sliding of the gravity slide 42, the limiting blocks 4 are pushed one by one by the deflection protrusions 45 installed at the end. When the gravity slide 42 is stable, under the action of gravity, the middle part of the gravity slide 42 is aligned with the release block 27, and under the action of the deflection protrusions 45 at both ends of the gravity slide 42, the limiting blocks 4 aligned with the two ends of the gravity slide 42 are pushed and extended into the moving groove 43 through the limiting groove 41. When the storage box 11 deflects under the action of inertia, the storage box 11 pulls the limiting spring 25 and the release block 27. At this time, the corresponding gravity slide 4 The limit blocks 4 at both ends of 2 are located on the movement path of the slow-release block 27, so the slow-release block 27 is limited, so that the slow-release block 27 can only slide within the distance between the two limit blocks 4. After the slow-release block 27 is limited, the rotation range of the storage box 11 is limited, thereby preventing the gravimeter 1 from deflecting too much. When the base 2 and the adjustment rail 26 deviate from the horizontal plane, the gravity slide 42 slides under the action of gravity and always remains in the horizontal direction. When the gravity slide 42 slides again, the limit blocks 4 that have been pushed shrink back into the limit groove 41 under the repulsive action of the magnetic sheet 44, and then when the adjustment rail 26 moves compared to the horizontal plane, the limit range of the limit blocks 4 is readjusted, and the deflection of the storage box 11 under the action of gravity is coordinated, so that the gravimeter 1 is always maintained within a certain angle compared to the horizontal plane, thereby reducing the probability of failure of the gravimeter 1 during transportation.

[0064] Embodiment 3

[0065] This embodiment is improved on the basis of the second embodiment. Figure 1-6 An extension frame 5 is fixedly mounted on the support frame 21, and an extension plate 51 is slidably mounted inside the extension frame 5. A driven groove 52 is provided at the bottom of the adjustment rail 26, and a driven rod 53 is mounted on the extension plate 51. The driven rod 53 extends to the inside of the adjustment rail 26 through the driven groove 52, and the driven rod 53 is located on the moving path of the release block 27.

[0066] An extension slot 54 is fixedly installed on the extension plate 51, and the driven rod 53 is slidably installed in the extension slot 54. A driven spring 55 is fixedly installed in the extension slot 54, and the driven spring 55 is fixedly connected to the driven rod 53;

[0067] Under the action of inertia, when the storage box 11 deflects, the release block 27 moves under the pull of the limit spring 25, and the release block 27 pushes the follower rod 53 to move when it moves. The follower rod 53 pushes the extension plate 51 to extend through the follower spring 55. The extension plate 51 cooperates with the base 2 to support the entire device, which can effectively reduce the probability of the entire equipment tipping over. At the same time, the follower spring 55 makes the follower rod 53 and the extension plate 51 elastically transmitted. When the extension plate 51 is hindered from extending, the follower rod 53 can compress the follower spring 55, so that the storage box 11 can still deflect to a certain extent, thereby reducing the deflection angle of the storage box 11 while reducing vibration.

[0068] A microgravity measurement device method, the method comprising the following steps:

[0069] S1: placing the gravimeter 1 in the storage box 11, and after the placement is completed, filling the buffer cotton sheet into the gap between the gravimeter 1 and the storage box 11;

[0070] S2: After the filling is completed, the device is placed on the transport equipment. Under the action of gravity, the storage box 11 and the support frame 21 rotate on the base 2, and the adjustment rail 26 is installed with a gravity block 28 at one end and tilted toward the base 2;

[0071] S3: The gravity slide 42 slides in the moving groove 43. The gravity slide 42 drives the deflection protrusion 45 to move during the sliding process. During the movement of the deflection protrusion 45, the limit block 4 is pushed to slide in the limit groove 41. When the gravity slide 42 is stable, the two limit blocks 4 corresponding to the deflection protrusion 45 extend to the inside of the adjustment rail 26.

[0072] S4: When the storage box 11 slides due to vibration or inertia, the storage box 11 pulls the release block 27 to move through the limit spring 25. When the release block 27 moves, it pushes the driven rod 53 and the extension plate 51 to move, and cooperates with the base 2 to support the entire device;

[0073] S5: After the entire device is transported to the measuring point, the entire device is placed on the measuring point. Under the action of gravity, the storage box 11 rotates and automatically deflects to level the gravimeter 1. The staff measures the gravity of the measuring point by themselves.

When the gravity slide plate (42) is stable, the two limit blocks (4) corresponding to the deflection protrusion (45) extend into the inside of the adjustment rail (26); S4: When the storage box (11) slides due to vibration or inertia, the storage box (11) pulls the slow-release block (27) to move through the limit spring (25), and the slow-release block (27) pushes the driven rod (53) and the extension plate (51) to move, and cooperates with the base (2) to support the entire device; S5: After the entire device is transported to the measuring point, the entire device is placed on the measuring point. Under the action of gravity, the storage box (11) rotates and automatically deflects to level the gravimeter (1). The staff measures the gravity of the measuring point by themselves.
