Description

Technical Field

[0001] This invention relates to the field of gravimeter technology, and more specifically to a gravimeter support and adjustment platform device. Background Technology

[0002] A gravimeter, also known as a gravitational accelerometer, is an instrument used to determine the acceleration due to gravity. There are two types: absolute gravimeters and relative gravimeters. Absolute gravimeters measure the absolute gravity at a point on the Earth's surface with an accuracy of tens of microgals; relative gravimeters measure the difference in gravity between two points on the Earth's surface with an accuracy of 10–20 μGal. Gravimeters usually refer to relative gravimeters. Gravimeters are widely used in measuring the Earth's gravitational field, observing solid tides, monitoring crustal deformation, and in gravity exploration.

[0003] When researchers use gravimeters for outdoor measurements, current gravimeter support and adjustment platform devices often lack sufficient terrain adaptability. In some areas with soft soil, these surfaces cannot provide a stable support foundation for traditional platforms in harsh environments. For example, in windy weather, the wind will act directly on the gravimeter, leading to the risk of the gravimeter tipping over and breaking. Summary of the Invention

A circular ring plate is slidably connected to the top wall of the base. Multiple rectangular frames are evenly distributed on the top of the circular ring plate. Each rectangular frame has multiple sets of air guiding mechanisms on its inner sidewall. Each set of air guiding mechanisms includes a guide plate rotatably connected to the inner sidewall of the rectangular frame via a circular shaft. An outer annular rack is fixedly connected to the top wall of the circular ring plate. A circular cavity is formed in the inner wall of the mounting base, and an inner annular rack is slidably connected to the inner wall of the cavity. Multiple rotating rods are rotatably connected through the sidewall of the mounting base, and both ends of each rotating rod are fixedly connected to...

[0007] Preferably, the reinforcing pile has a spiral groove on its side wall, and a guide column is fixedly connected to the inner side wall of the guide tube, with the guide column and the spiral groove being slidably connected.

[0008] Preferably, the inner wall of the support column has an inner cavity, and multiple stabilizing rods are evenly distributed and slidably connected through the inner sidewall of the inner cavity. A tension spring is sleeved and fixedly connected to the sidewall of the stabilizing rod, and the tension spring is fixedly connected to the inner sidewall of the inner cavity.

[0009] Preferably, the inner wall of the inner cavity is provided with a sliding cavity, and a piston rod is slidably connected to the inner wall of the sliding cavity, with a frustum block fixedly connected to one end of the piston rod.

[0010] Preferably, the base has multiple columnar boxes fixedly connected to its bottom wall, and the inner side wall of each columnar box is slidably connected with a sliding plug. One end of the reinforcing pile passes through the inner wall of an adjacent columnar box and is rotatably connected to the side wall of the sliding plug.

[0011] Preferably, a connecting pipe is fixedly connected through the inner wall of the columnar box, and the other end of the connecting pipe is fixedly connected to the inner wall of the adjacent sliding cavity.

[0012] Preferably, a T-shaped limiting rod is slidably connected through the inner wall of the cavity, and a tension spring is fixedly connected to the side wall of the T-shaped limiting rod. The tension spring is fixedly connected to the side wall of the rectangular frame. A limiting groove is opened on the side wall of the wedge plate, and the limiting groove is inserted and connected to the T-shaped limiting rod after moving a certain distance with the wedge plate.

[0013] Preferably, the drive gear and the toothed belt are meshed together, the first gear and the outer ring rack are meshed together, the second gear and the inner ring rack are meshed together, and the wedge-shaped push plate and the wedge plate slide against each other.

[0014] Preferably, the plurality of support columns are fixedly connected to the bottom wall of the base, and the mounting base is fixedly connected to the top of the base.

[0015] Compared with existing technologies, the advantages of this invention are: 1. When the ambient wind force in the measurement area where the level is located gradually increases, since the multiple guide plates inside each rectangular frame are in a horizontal state, when the wind force acts on the multiple guide plates, it causes the ring plate to slide to produce a rotation effect. Furthermore, the wedge-shaped push plate provided on each rectangular frame will contact the side wall of an adjacent outer convex plate after moving a certain distance. If the wind force does not continue to increase, the wedge-shaped push plate will stop moving under the interference of the outer convex plate after it contacts the adjacent outer convex plate. 2. When the wind force continues to increase, there is a safety hazard of the gravimeter being blown over by the wind. At this time, the kinetic energy of the rectangular frame driving the wedge pusher increases. By setting up structures such as wedge pushers, circular shafts and drive gears, multiple guide plates are tilted upwards. When the external wind force impacts the tilted upward guide plates, the airflow is forced to be guided obliquely upwards. According to the momentum theorem, the upward guidance of the airflow by the guide plates will result in a reaction force in the direction of downwards, thus effectively generating a downward force. That is, for this device, a downward force can be obtained at this time, which makes the device more stable. 3. When the wind pushes the multiple guide plates in the rectangular frame to move, causing the rectangular frame to slide around the side of the gravimeter, the rectangular frame and multiple guide plates can form a local blocking area by changing the airflow direction, similar to the principle of a wind deflector. The rectangular frame and multiple guide plates can disperse wind pressure and reduce the wind intensity that directly impacts the gravimeter. This design can reduce the direct effect of lateral wind on the gravimeter and form a dynamic barrier. 4. During the sliding process of the circular plate, by setting the first gear, rotating rod and second gear and other structures, the L-shaped rod drives the circular block fixedly connected to it to move synchronously. Since the circular block is embedded and rotated on the side wall of the reinforcing pile, the circular block will drive the reinforcing pile to move synchronously, so that one end of the reinforcing pile is inserted into the soil again, improving the support effect on the gravimeter and preventing the gravimeter from being blown over by strong winds. 5. During the movement of the reinforcing pile, since the reinforcing pile has a spiral groove on its side wall and a guide column is fixed on the inner side wall of the guide tube, and the guide column and the spiral groove are slidably connected, the reinforcing pile will rotate during the insertion into the soil, which facilitates the insertion of the reinforcing pile into the soil. 6. By setting up structures such as connecting pipes, cylindrical boxes, and piston columns, the pile will drive the sliding plug to move synchronously during the movement of the pile. This will squeeze mineral oil into the sliding cavity and push the piston column and the frustum block to move. This will cause multiple stabilizing rods to move a distance away from the inner cavity and insert into the soil. Multiple stabilizing rods will extend outward from the bottom side wall of the support column, thereby improving the stability of the support column and avoiding safety hazards such as tipping over when the gravimeter is in strong winds.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Reference Figure 1 - Figure 10 A gravimeter support and adjustment platform device includes a base 1, a mounting base 2, and multiple support columns 31. The top wall of the base 1 has an annular groove, in which a circular ring plate 3 is slidably connected. Multiple rectangular frames 4 are evenly distributed on the top of the circular ring plate 3. Each rectangular frame 4 has multiple sets of air guiding mechanisms on its inner sidewall. Each air guiding mechanism includes a guide plate 6 rotatably connected to the inner sidewall of the rectangular frame 4 via a circular shaft 5. An outer annular rack 17 is fixedly connected to the top wall of the circular ring plate 3. The inner wall of the mounting base 2 has a circular cavity 39 (e.g., ...). Figure 2 and Figure 3 As shown), an inner annular rack 21 is slidably connected to the inner wall of the cavity 39. Multiple rotating rods 18 are rotatably connected through the side wall of the mounting base 2. A first gear 19 and a second gear 20 are fixedly connected to the two ends of each rotating rod 18. A reciprocating screw 23 is rotatably connected through the inner walls of the base 1 and the mounting base 2. The reciprocating screw 23 is a bidirectional automatic reciprocating screw, meaning that the nut can automatically reverse direction at the end of its stroke regardless of whether the screw rotates forward or backward. The side wall of the reciprocating screw 23 is fixedly connected to the inner annular rack 21 via multiple crossbars 41. A threaded sleeve 40 is threaded onto the side wall of the reciprocating screw 23. A connecting plate 24 (as shown) is installed on the bottom wall of the threaded sleeve 40 via an electromagnetic clutch 42. Figure 10 As shown), the electromagnetic clutch 42 is existing technology. The electromagnetic clutch 42 uses the principle of electromagnetic induction and the friction between the inner and outer friction plates to enable the driven part to engage or disengage with two rotating parts in the mechanical transmission system without the driving part stopping its rotation. Multiple L-shaped rods 25 are fixedly connected to the connecting plate 24. Each support column 31 has a guide tube 26 fixedly connected to its side wall through an extension column. A reinforcing pile 27 slides through the guide tube 26. A rotating ring block 30 is embedded in the side wall of the reinforcing pile 27. The end of the L-shaped rod 25 away from the connecting plate 24 is fixedly connected to the adjacent ring block 30.

[0020] The mounting base 2 has multiple protruding plates 11 fixedly connected to its side wall. The protruding plates 11 are semi-cylindrical in structure. A cavity 7 is opened in the inner wall of the rectangular frame 4. A wedge plate 9 is slidably connected to the inner wall of the cavity 7. A toothed belt 10 is fixedly connected to the side wall of the wedge plate 9. Figure 6As shown), a drive gear 8 is fixedly connected to one end of the circular shaft 5, and a wedge-shaped push plate 12 is slidably connected through the side wall of the cavity 7. A reset spring 13 is fixedly connected to the side wall of the wedge-shaped push plate 12, and the reset spring 13 is fixedly connected to the side wall of the rectangular frame 4.

[0021] The reinforcing pile 27 has a spiral groove 28 on its side wall, and a guide column 29 is fixedly connected to the inner side wall of the guide tube 26. The guide column 29 and the spiral groove 28 are slidably connected.

[0022] The inner wall of the support column 31 has an inner cavity 32 (such as...) Figure 8 As shown), multiple stabilizing rods 34 are evenly distributed and slidably connected to the inner sidewall of the inner cavity 32. Tension springs 35 are fixedly connected to the sidewall of the stabilizing rods 34, and the tension springs 35 are fixedly connected to the inner sidewall of the inner cavity 32.

[0023] The inner wall of the inner cavity 32 is provided with a sliding cavity 38, and a piston column 33 is slidably connected to the inner wall of the sliding cavity 38. One end of the piston column 33 is fixedly connected to a frustum block 43.

[0024] The base 1 has multiple columnar boxes 36 fixedly connected to its bottom wall. The inside of the columnar boxes 36 is filled with mineral oil. The inner side wall of the columnar boxes 36 is sealed and slidably connected with a sliding plug 37. One end of the reinforcing pile 27 passes through the inner wall of the adjacent columnar box 36 and is rotatably connected to the side wall of the sliding plug 37.

[0025] A connecting pipe 44 is fixedly connected through the inner wall of the columnar box 36. The other end of the connecting pipe 44 is fixedly connected to the inner wall of the adjacent sliding cavity 38. A balance hole is opened on the top wall of the columnar box 36.

[0026] A T-shaped limiting rod 15 is slidably connected through the inner wall of cavity 7. A tension spring 16 is fixedly connected to the side wall of T-shaped limiting rod 15. The tension spring 16 is fixedly connected to the side wall of rectangular frame 4. A limiting groove 14 is opened on the side wall of wedge plate 9. After moving a certain distance with wedge plate 9, the limiting groove 14 is inserted and connected to T-shaped limiting rod 15.

[0027] The drive gear 8 and the toothed belt 10 are meshed and connected, the first gear 19 and the outer ring rack 17 are meshed and connected, the second gear 20 and the inner ring rack 21 are meshed and connected, and the wedge-shaped push plate 12 and the wedge plate 9 slide against each other.

[0028] A level (not shown in the figure) is installed on the base 1, multiple support columns 31 are fixedly connected to the bottom wall of the base 1, and the mounting base 2 is fixedly connected to the top of the base 1. In this invention, the user first fixes the gravimeter 22 inside the mounting base 2, then inserts the multiple support columns 31 set at the bottom of the base 1 into the soil of the area where gravity acceleration needs to be measured, and uses a level to determine whether the base 1 and the gravimeter 22 are level.

[0029] In the initial state, the multiple guide plates 6 inside each rectangular frame 4 are horizontal to each other (e.g., Figure 1 As shown), at this time, the multiple guide plates 6 in the rectangular frame 4 are parallel to each other, thus minimizing the resistance to the wind and ensuring that subsequent operations will not be initiated due to misjudgment in a normal wind environment. When the ambient wind force in the measurement area gradually increases, the enhanced wind force acts on the multiple guide plates 6 and the rectangular frame 4 under the action of the continuously increasing wind force. The rectangular frame 4 will drive the circular ring plate 3 to slide to produce a rotation effect. Then the circular ring plate 3 will move synchronously with the multiple rectangular frames 4 fixed on its top. The wedge-shaped push plate 12 provided on each rectangular frame 4 will contact the side wall of an adjacent outer convex plate 11 after moving a certain distance. If the wind force does not continue to increase, the wedge-shaped push plate 12 will stop moving under the interference of the outer convex plate 11 after it contacts the adjacent outer convex plate 11.

[0030] As the wind continues to increase, there is a safety hazard that the gravimeter 22 may be blown over. At this point, the kinetic energy of the rectangular frame 4 driving the wedge-shaped pusher 12 increases. The wedge-shaped pusher 12 will then slide against the side wall of the outer convex plate 11, squeezing the corresponding return spring 13. Furthermore, the wedge-shaped pusher 12 will also cause the wedge-shaped plate 9, which is sliding against it, to move a certain distance. The wedge-shaped plate 9 will then drive the toothed belt 10, which is fixedly connected to it, to move synchronously. The toothed belt 10 will then drive the drive gear 8, which is meshed with it, to rotate at a certain angle. The drive gear 8, through the round shaft 5 fixedly connected to it, will drive the guide plate 6 to rotate at a certain angle. Consequently, all the guide plates 6 will be in an upward tilted state. During the sliding process of the wedge plate 9, when the limiting groove 14 and the T-shaped limiting rod 15 on the side wall of the wedge plate 9 correspond, the T-shaped limiting rod 15 will be inserted into the limiting groove 14 under the elastic force of the tension spring 16, thereby limiting the wedge plate 9. At this time, the multiple guide plates 6 will be in a locked and stable state. When the external wind force impacts the inclined upward guide plate 6, the airflow is forced to be guided obliquely upward. According to the momentum theorem, the upward guidance of the airflow by the guide plate 6 will result in a reaction force in the downward direction, thereby effectively generating a downward force. That is, for this device, a downward force can be obtained at this time, which can make the device more stable.

[0031] When the wind pushes the multiple guide plates 6 in the rectangular frame 4 to move, causing the rectangular frame 4 to slide in a circle around the side of the gravimeter 22, the rectangular frame 4 and the multiple guide plates 6 can form a local blocking area by changing the airflow direction, similar to the principle of a wind deflector. The rectangular frame 4 and the multiple guide plates 6 can disperse the wind pressure and reduce the wind intensity that directly impacts the gravimeter 22. This design can reduce the direct effect of the lateral wind force on the gravimeter 22 and form a dynamic barrier.

[0032] Since the outer ring rack 17 is meshed with the first gear 19, and the second gear 20 is meshed with the inner ring rack 21, during the sliding of the ring plate 3, the ring plate 3 will drive the first gear 19, the rotating rod 18, and the second gear 20 to rotate via the outer ring rack 17. In turn, the second gear 20 will drive the inner ring rack 21 to slide, thus producing a rotational effect. The inner ring rack 21 will then drive the reciprocating screw 23 to rotate via multiple crossbars 41. After the reciprocating screw 23 rotates, the threaded sleeve 40 connected to its side wall will move along the reciprocating... The lead screw 23 moves axially, and the screw sleeve 40 drives multiple L-shaped rods 25 to move synchronously through the electromagnetic clutch 42 and the connecting plate 24. At this time, the electromagnetic clutch 42 is energized by the controller, so that the L-shaped rods 25 drive the ring block 30 fixedly connected to them to move synchronously. Since the ring block 30 is embedded and rotated on the side wall of the reinforcing pile 27, the ring block 30 will drive the reinforcing pile 27 to move synchronously, so that one end of the reinforcing pile 27 is inserted into the soil again, improving the support effect on the gravimeter 22 and preventing the gravimeter 22 from being blown over by strong winds.

[0033] Meanwhile, during the movement of the reinforcing pile 27, because the reinforcing pile 27 has a spiral groove 28 on its side wall and a guide post 29 is fixed to the inner side wall of the guide tube 26 (such as... Figure 8 and Figure 9 As shown), the guide post 29 and the spiral groove 28 are slidably connected. Therefore, the reinforcing pile 27 will rotate during insertion into the soil, facilitating its insertion. Simultaneously, the reinforcing pile 27 will drive the sliding plug 37 to move synchronously. The sliding plug 37 will slide a certain distance within the cylindrical box 36. Since the cylindrical box 36 is filled with mineral oil, the sliding plug 37 will squeeze the mineral oil into the connecting pipe 44 during its movement, and ultimately, this portion of mineral oil will enter the sliding cavity 38. When the piston column 33 is pushed to slide a certain distance, the truncated cone block 43 fixed at one end of the piston column 33 will come into contact with one end of multiple stabilizing rods 34, and push the multiple stabilizing rods 34 to move a certain distance away from the inner cavity 32. Then, these stabilizing rods 34 will be inserted into the soil after being pushed by the truncated cone block 43. Multiple stabilizing rods 34 will extend outward from the bottom side wall of the support column 31, thereby improving the stability of the support column 31 and avoiding safety hazards such as the gravimeter 22 tipping over when the external wind is strong.

[0034] This device, by setting up parallel guide plates 6, wedge-shaped push plates 12 and outward convex plates 11, will not trigger subsequent operations in normal wind conditions, thus avoiding excessive support and adjustment of the gravimeter 22 in normal environments. However, when the wind gradually increases and reaches a certain "critical value", the wind force is used to continuously improve the support and adjustment effect on the gravimeter 22, so as to avoid the gravimeter 22 being affected by strong winds and causing safety hazards.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
