Description

Technical Field

[0001] The embodiments of this utility model relate to the field of exploration equipment technology, specifically to a portable shallow seismic exploration correction instrument. Background Technology

[0002] In the field of shallow seismic exploration, seismic correction instruments play a crucial role. They preprocess acquired seismic wave data to eliminate the influence of factors such as surface conditions and wave field propagation characteristics, providing a reliable basis for subsequent geological interpretation. However, existing seismic correction instruments have many inconveniences when operating in the field.

[0003] Traditional seismic exploration correction instruments typically employ a fixed shell structure with a less compact internal module layout, resulting in a large overall size and weight. When facing complex terrain environments such as mountains, deserts, and jungles, exploration personnel find it difficult to easily carry and quickly transport the equipment, significantly reducing the efficiency of field operations.

[0004] Furthermore, most of the signal interfaces, control panels, and other components of the existing equipment are exposed, making them susceptible to damage from bumps and squeezing during transport. This also increases the space occupied by the equipment and further complicates transportation. Additionally, accidental activation is common during transport, and the lack of effective protective measures makes it vulnerable to damage from rain, dust, and other harsh environments. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides a portable shallow seismic exploration correction instrument, which solves the technical problem that existing seismic exploration correction instruments in the field are inconvenient to carry and transport.

[0006] According to one aspect, at least one embodiment of the present invention provides a portable shallow seismic exploration correction instrument, comprising:

[0007] A housing for housing the exploration instrument;

[0008] Rollers, which are rotatably connected to the bottom of the housing for contact with the ground;

[0009] A pull rod unit is disposed on the side wall of the housing, and the pull rod unit includes:

[0010] Mounting plate, the mounting plate is disposed on the side wall of the housing, and the mounting plate has an opening facing away from the roller;

[0011] A first slide rod is slidably disposed within the first slide groove, and the first slide rod is arranged to extend out of the first slide groove after sliding.

[0012] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of the present invention, the first slide rod has a second slide groove opened along the length direction, and the pull rod unit further includes:

[0013] The second slide rod is slidably disposed within the second slide groove; the second slide rod is arranged such that after sliding within the second slide groove, it can drive the first slide rod to slide within the first slide groove.

[0014] For example, in a portable shallow seismic exploration correction instrument provided by at least one embodiment of the present invention, the second slide bar has a third slide groove along its length, and the portable shallow seismic exploration correction instrument further includes:

[0015] The third slide rod is slidably disposed in the first slide groove, and the second slide rod is swung on the third slide rod. After the box is laid flat, the second slide rod slides out of the first slide groove and can swing on the third slide rod so that the length direction of the second slide rod is perpendicular to the ground.

[0016] A probe is slidably disposed within the third groove, and the probe is arranged such that it can extend out of the third groove after sliding, for extending into the ground to perform detection.

[0017] For example, in a portable shallow seismic exploration and correction instrument provided in at least one embodiment of the present invention, the probe has an operating part on the side wall away from the housing. The operating part extends out of the third slide groove and the second slide groove, and is located outside the first slide rod, for driving the probe to slide in the third slide groove.

[0018] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of the present invention, the operating part has a positioning hole, the second slide bar has a mounting hole, and the positioning hole and the mounting hole are locked by a locking rod to limit the position of the operating part relative to the second slide bar.

[0019] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of the present invention, the locking rod is slidably disposed in the mounting hole, and an elastic element is directly provided between the locking rod and the inner wall of the mounting hole. The elastic element is used to provide a force for the locking rod to approach the positioning hole.

[0020] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of the present invention, one end of the locking rod extends out of the mounting hole and has a gripping part. The gripping part is used to move the locking rod out of the positioning hole after being gripped, so as to release the position of the operating part relative to the second slide rod.

[0021] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of this utility model, the housing includes:

[0022] The main body, wherein the roller is rotatably connected to the bottom of the main body, and the mounting plate is disposed on the outer wall of the main body;

[0023] A cover, one side of which is hinged to one side of the main body, is arranged so that, when rotated, the cover and the main body together house the exploration instrument.

[0024] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of the present invention, the mounting plate has a foot pad on the side away from the main body, and the foot pad is used to contact the ground after the box is laid flat.

[0025] For example, in a portable shallow seismic exploration correction instrument provided in at least one embodiment of the present invention, the main body has a snap-lock on the side away from the hinge point with the cover, and the snap-lock is used to limit the position of the cover relative to the main body.

[0026] The beneficial effects of the embodiments of this utility model are as follows:

[0027] In this invention, the housing provides storage space for the exploration instrument, isolating it from the external environment and preventing direct exposure of components such as signal interfaces and control panels. This reduces the risk of damage caused by bumps and squeezing during transport, while the compact layout helps reduce the overall size of the equipment. Rollers are rotatably connected to the bottom of the housing, forming a movable support structure. Combined with the sliding extension function of the pull rod unit, this allows operators to move the equipment like a suitcase, significantly reducing the difficulty of transporting it in complex terrains such as mountains and deserts, and improving the convenience of field operations.

[0044] like Figures 1-2The diagram illustrates a portable shallow seismic exploration and correction instrument according to an embodiment of the present invention, comprising a housing 1, rollers 3, and a pull rod unit 4. The housing 1 houses the exploration instrument 2, and rollers 3 are rotatably connected to its bottom. These rollers 3 are connected to a bearing seat at the bottom of the housing 1 via an axle, allowing free rotation around the axle to accommodate movement in different directions. The pull rod unit 4 is located on the side wall of the housing 1 and includes a mounting plate 41 and a first sliding rod 42. The mounting plate 41 is a flat plate structure, fixedly connected to the side wall of the housing 1. A first sliding groove 411 is formed on its side facing the outside of the housing 1. The opening of the first sliding groove 411 faces away from the bottom of the housing 1 where the rollers 3 are located, so that the first sliding rod 42 extends towards the top of the housing 1. The first sliding rod 42 is a rod-shaped structure, and its cross-sectional shape matches the cross-sectional shape of the first sliding groove 411, for example, both being rectangular, to ensure that the first sliding rod 42 can slide within the first sliding groove 411 along the extension direction of the groove. One end of the first slide rod 42 is located inside the first slide groove 411, and the other end can slide out of the first slide groove 411 to form an operating end for the user to hold. When it is necessary to move the box 1, the user applies force to pull the first slide rod 42, causing it to slide out along the first slide groove 411. At this time, the user can hold the extended end of the first slide rod 42 and use the rotation of the roller 3 to move the box 1 by dragging. When the pull rod unit 4 is not needed, the first slide rod 42 is pushed to retract into the first slide groove 411, reducing the overall space occupied by the box 1 and facilitating storage and transportation.

[0045] The housing 1 provides space for the exploration instrument 2, isolating it from the external environment and preventing direct exposure of components such as signal interfaces and control panels. This reduces the risk of damage from bumps and squeezing during transport, while the compact layout helps reduce the overall size of the equipment. Rollers 3 are rotatably connected to the bottom of the housing 1, forming a movable support structure. Combined with the sliding extension function of the pull rod unit 4, this allows operators to move the equipment like a suitcase, significantly reducing the difficulty of transporting it in complex terrains such as mountains and deserts, and improving the convenience of field operations. The opening of the first sliding groove 411 on the mounting plate 41 faces away from the roller 3, ensuring a reasonable force distribution between the extension direction of the first sliding rod 42 and the support direction of the roller 3. This ensures the stability of the housing 1 during dragging and avoids tilting or tipping due to unreasonable force direction of the pull rod. The matching design of the first sliding rod 42 and the first sliding groove 411 ensures smooth sliding and prevents the first sliding rod 42 from disengaging from the groove during movement through structural limiting, enhancing the reliability of the pull rod unit 4.

[0046] like Figures 3-4As shown, the first slide rod 42 has a second slide groove 421 extending along its length. The extension direction of the second slide groove 421 is consistent with the length direction of the first slide rod 42. The second slide rod 43 is a rod-shaped structure, and its cross-sectional shape matches the cross-sectional shape of the second slide groove 421, for example, both are rectangular. The second slide rod 43 is slidably disposed within the second slide groove 421. One end of the second slide rod 43 is located within the second slide groove 421, and the other end can slide out of the second slide groove 421. A limiting structure, such as a protrusion, is provided at the end of the second slide rod 43 near the first slide rod 42. The protrusion contacts and engages with the inner wall of the first slide groove 411. When the second slide rod 43 slides within the second slide groove 421, the protrusion drives the first slide rod 42 to slide within the first slide groove 411. Specifically, when the user applies force to pull the extended end of the second slide rod 43, the second slide rod 43 slides along the second slide groove 421, and the protrusion at its end pushes the first slide rod 42 to slide along the first slide groove 411, thereby realizing the synchronous movement of the first slide rod 42 and the second slide rod 43; conversely, when the user pushes the second slide rod 43, the protrusion drives the first slide rod 42 to retract.

[0047] The two-stage sliding structure of the second slide rod 43 and the first slide rod 42 allows the overall length of the pull rod unit 4 to be adjusted by the relative sliding of the two slide rods, which can adapt to the usage needs of operators of different heights and improve operating comfort. The matching design of the second slide groove 421 and the second slide rod 43 ensures the stability of their relative positions during sliding. The setting of the limiting structure ensures that the sliding of the second slide rod 43 can reliably drive the movement of the first slide rod 42, avoiding the phenomenon of disengagement or jamming between the slide rods, and enhancing the smoothness of operation and structural reliability of the pull rod unit 4.

[0048] like Figure 3 , Figure 4 and Figure 7 As shown, the second slide rod 43 has a third slide groove 431 along its length. The third slide rod 44 is a rod-shaped structure, and its cross-sectional shape matches the cross-sectional shape of the first slide groove 411. The third slide rod 44 is slidably disposed within the first slide groove 411. The second slide rod 43 is oscillatingly disposed on the third slide rod 44 via a hinge structure. For example, one end of the third slide rod 44 is provided with a pin, and a hinge hole is provided at the corresponding position of the second slide rod 43. The second slide rod 43 is sleeved on the pin through the hinge hole, allowing the second slide rod 43 to swing around the pin. When the box 1 is laid flat, the third slide rod 44 slides out along the first slide groove 411, causing the second slide rod 43 to slide out of the first slide groove 411. At this time, the operator can swing the second slide rod 43 around the pin so that its length direction is perpendicular to the ground. The detection rod 5 is a rod-shaped structure, and its cross-sectional shape matches the cross-sectional shape of the third slide groove 431. The detection rod 5 is slidably set in the third slide groove 431. One end of the detection rod 5 is located in the third slide groove 431, and the other end can slide out of the third slide groove 431 for extending into the ground for detection.

[0049] The hinged structure between the third slide rod 44 and the second slide rod 43 allows the second slide rod 43 to be converted into a vertical support state when the housing 1 is laid flat. Combined with the sliding extension function of the detection rod 5, this realizes the transformation of the equipment from the transportation state to the detection operation state. The third slide groove 431 provides sliding guidance for the detection rod 5, ensuring the accuracy of the direction when the detection rod 5 extends into the ground. The hinged structure allows the second slide rod 43 to adjust its angle according to operational needs, enhancing the adaptability of the equipment under different terrain conditions.

[0050] like Figures 3-6 As shown, an operating part 51 is provided on the side wall of the end of the probe 5 away from the housing 1. The operating part 51 is a protruding structure, and its shape is, for example, cuboid. The operating part 51 can extend out of the third slide groove 431 and the second slide groove 421, and is located outside the first slide rod 42. The operator holds the operating part 51 and applies force to push or pull the probe 5, causing it to slide in the third slide groove 431, thereby controlling the extension or retraction state of the probe 5.

[0051] The operating part 51 provides the operator with a direct point of force application, facilitating the sliding operation of the probe rod 5 and avoiding the problem of difficulty in applying force when the probe rod 5 is hidden in the groove. The protruding structure of the operating part 51 matches the size of the groove, ensuring that the operating part 51 will not disengage from the groove during sliding, while effectively transmitting the operator's force, improving the convenience and reliability of the operation of the probe rod 5, and enabling the operator to quickly adjust the extension length of the probe rod 5 to meet the needs of different detection depths.

[0052] like Figures 3-6 As shown, the operating part 51 has a positioning hole 52, which is a circular hole penetrating the operating part 51. The second slide rod 43 has a mounting hole 432 at a corresponding position, which is also a circular hole penetrating the second slide rod 43. When the axis of the positioning hole 52 is aligned with that of the mounting hole 432, the locking rod 6 can pass through the positioning hole 52 and the mounting hole 432 to lock the position of the operating part 51 relative to the second slide rod 43. The locking rod 6 is a cylindrical rod-shaped structure, and its diameter matches the inner diameter of the positioning hole 52 and the mounting hole 432. A limit cap is provided at one end of the locking rod 6 to prevent the locking rod 6 from completely disengaging from the mounting hole 432.

[0053] The locking rod 6, in conjunction with the positioning hole 52 and the mounting hole 432, forms a mechanical locking structure. This effectively restricts the sliding of the operating part 51 relative to the second sliding rod 43, ensuring that the probe rod 5 maintains a fixed extension length during the detection process. This prevents the probe rod 5 from accidentally sliding due to external vibration or collision, which could affect the accuracy of the detection data.

[0054] like Figures 3-6As shown, the locking rod 6 is slidably disposed within the mounting hole 432. An elastic element 7 is disposed between the locking rod 6 and the inner wall of the mounting hole 432. The elastic element 7 is, for example, a spring. The spring is sleeved on the locking rod 6, with one end abutting against the bottom of the mounting hole 432 and the other end abutting against the limiting cap of the locking rod 6. The elastic force provided by the elastic element 7 makes the locking rod 6 always tend to move closer to the positioning hole 52. When the positioning hole 52 is aligned with the mounting hole 432, the locking rod 6 automatically inserts into the positioning hole 52 under the action of the elastic element 7, thereby achieving locking.

[0055] The elastic element 7 enables the locking rod 6 to automatically reset and insert into the positioning hole 52, eliminating the need for manual alignment and insertion by the operator. This simplifies the locking operation process and improves work efficiency. The continuous elastic force provided by the elastic element 7 ensures a tight fit between the locking rod 6 and the positioning hole 52, preventing loosening of the locking rod 6 due to vibration or other factors, thus enhancing the reliability of the locking structure. This design converts elastic potential energy into locking force, automating the locking process and improving the convenience and stability of equipment operation.

[0056] like Figures 3-6 As shown, one end of the locking rod 6 extends out of the mounting hole 432 and has a gripping part 61. The gripping part 61 has a disc-shaped structure, and its diameter is larger than the inner diameter of the mounting hole 432 to prevent the locking rod 6 from sliding completely into the mounting hole 432. By gripping the gripping part 61, the operator applies force to pull the locking rod 6, overcoming the elastic force of the elastic element 7, causing the locking rod 6 to move out of the positioning hole 52, releasing the positional restriction on the operating part 51. At this time, the operator can freely slide the probe rod 5.

[0057] The grip 61 provides the operator with a convenient point of application for unlocking; the lock can be released with a simple pulling motion, making the operation intuitive and effortless. The size design of the grip 61 ensures that the operator can hold it stably.

[0058] like Figure 1 , Figure 2 and Figure 8 As shown, the housing 1 includes a main body 11 and a cover 12. The main body 11 is a rectangular shell structure. The rollers 3 are rotatably connected to the bearing seats at the bottom of the main body 11 via axles. The mounting plate 41 is fixedly connected to the outer wall of the main body 11. The cover 12 is a rectangular plate structure that matches the main body 11. One side of the cover 12 is connected to one edge of the main body 11 via a hinge. The hinge includes two hinge pieces, which are fixedly connected to the cover 12 and the main body 11 respectively. The hinge pieces are connected by a pin, allowing the cover 12 to rotate around the pin. When the cover 12 rotates to fit against the main body 11, the two together form a closed space to accommodate the exploration instrument 2.

[0059] The main body 11 and the cover 12 are hinged together to form an openable and closable housing 1, facilitating the insertion and removal of the exploration instrument 2 by operators. The hinge design ensures smooth rotation and reliable connection of the cover 12. The cover 12 and the main body 11 together house the exploration instrument 2, enclosing its signal interface, control panel, and other components within the housing 1. This prevents exposure to impacts, pressure, rain, or dust, enhancing the equipment's protective performance. The enclosed structure of the housing 1 also reduces interference from the external environment during transportation, providing a stable working environment and ensuring the reliability and durability of the equipment under complex field conditions.

[0060] like Figure 1 , Figure 2 and Figure 8 As shown, a foot pad 13 is provided on the side of the mounting plate 41 away from the main body 11. The foot pad 13 has a flat structure, and its shape matches the outer contour of the mounting plate 41. The foot pad 13 is fixed to the mounting plate 41 by bolts or adhesive. When the box 1 is laid flat, the foot pad 13 contacts the ground, forming a support point, and together with the roller 3, supports the box 1, keeping the box 1 in a stable flat state.

[0061] The foot pads 13 provide additional support points when the housing 1 is laid flat, preventing tilting or tipping due to a shift in the center of gravity of the housing 1. Especially on uneven ground, the foot pads 13 increase the contact area between the housing 1 and the ground, distributing the weight of the housing 1 and improving stability. The fixed connection structure between the foot pads 13 and the mounting plate 41 ensures that they will not fall off during handling and operation. Together with the rollers 3 and the pull rod unit 4, the housing 1 can smoothly switch between transport and flat operation states, adapting to different usage scenarios and enhancing the environmental adaptability of the equipment.

[0062] like Figure 1 , Figure 2 and Figure 8 As shown, a snap-fit ​​lock 14 is provided on the side of the main body 11 away from the hinge point with the cover 12. The snap-fit ​​lock 14 includes a latch fixed to the main body 11 and a locking hole fixed to the cover 12. The latch is a hook-shaped structure, and the locking hole is a round hole that matches the latch. When the cover 12 is rotated to fit against the main body 11, the latch is inserted into the locking hole to form a snap-fit, restricting the position of the cover 12 relative to the main body 11 and ensuring that the box 1 is in a closed state.

[0063] The snap-lock 14 provides a reliable locking method for the connection between the cover 12 and the main body 11, preventing the cover 12 from being accidentally opened during transportation due to vibration or external force, and protecting the exploration instrument 2 inside the housing 1 from external environmental influences. The snap-lock structure of the latch and lock hole is simple and practical, allowing operators to manually insert or remove the latch, facilitating the opening and closing of the housing 1. This structure, in conjunction with the hinge structure, forms a stable closed system for the housing 1, improving the overall sealing and protective performance of the equipment, and ensuring the safety and integrity of the exploration instrument 2 during handling and storage.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
