A cover 2 is hinged to the left end of the upper surface of the housing 1 to close the upper opening of the housing 1. A protective rubber pad 5 is provided in the storage slot of the housing 1 to provide cushioning and shock absorption protection for the acquisition components, reducing damage to the data acquisition device caused by bumps during transportation on rugged mountain roads. A data receiver 3 is installed in the mounting slot at the right end of the protective rubber pad 5. The data receiver 3 can be a GA-RXB-3D model receiver, which can receive the acquired data. Data acquisition sensors 4 are placed in the placement slots at the left end of the protective rubber pad 5. The data acquisition sensors 4 can be IMD-100 model magnetic rod sensors to collect the secondary electric field and electromagnetic field spectrum formed by the discharge of the pore medium in oil and gas reservoirs. The cover 2... The middle part is provided with pressure plate 7, which is installed in conjunction with data acquisition sensor 4. Sliding column 8 is slidably connected in the sliding hole on the surface of pressure plate 7. Limiting pressure plate 9 is provided between the ends of two sliding columns 8 on the same pressure plate 7 that are close to the box body 1. Spring 10 is provided between the limiting plate of the sliding column 8 away from the end of the box body 1 and pressure plate 7. Spring 10 is movably sleeved on the outer arc surface of sliding column 8. After the box cover 2 is closed, the spring 10 is in a stretched state under the support of pressure plate 7. The elastic force generated by spring 10 is applied to the upper end of data acquisition sensor 4 by limiting pressure plate 9, pushing data acquisition sensor 4 completely into the interior of protective rubber pad 5. Lifting handle 11 is rotatably connected to the grooves on the left and right sides of box body 1 through rotating shaft 4, which facilitates lifting and moving box body 1. Buffer partition 12 is filled between the inner shell and outer shell of box body 1. Buffer partition 12 is EPS foam board, which increases the impact resistance of box body 1 and provides better protection for the acquisition device inside box body 1. Limiting mechanism 6 is also included.
[0019] Limiting mechanism 6 includes a lifting support plate 61 and a rotating plate 62. The lifting support plate 61 is vertically slidably connected to the inside of the housing 1 and is located below the protective rubber pad 5. The rotating plate 62 is set on the outer arc surface of the hinge shaft of the housing cover 2 and is connected to the lifting support plate 61 in a transmission manner. The limiting mechanism 6 also includes a connecting rotating plate 63, an inclined rotating plate 64, a sliding column 65, and a sliding groove 66.

During the rotation of the cover 2, the hinge shaft of the cover 2 drives the rotating plate 62 to rotate. Through the relative rotation of the connecting rotating plate 63 and the rotating plate 62, the upper end of the connecting rotating plate 63 is pulled upward. The connecting rotating plate 63 is rotatably connected to the support plate on the upper surface of the inclined rotating plate 64. The connecting rotating plate 63 applies an upward lifting force to the inclined rotating plate 64, causing the inclined rotating plate 64 to rotate counterclockwise.

During the movement, the spring 10 is in a stretched state. Under the elastic force of the spring 10, the limiting pressure plate 9 applies a downward force to the data acquisition sensor 4, pushing the data acquisition sensor 4 completely into the protective rubber pad 5. The protective rubber pad 5 provides good and effective buffer protection for the data acquisition sensor 4 and the data receiver 3, reducing damage to the acquisition device from collisions during transportation. After the acquisition device is moved to the designated position, the housing cover 2 is opened. During the rotation of the housing cover 2... The hinge shaft of the box cover 2 drives the rotating plate 62 to rotate. Through the relative rotation of the connecting rotating plate 63 and the rotating plate 62, the upper end of the connecting rotating plate 63 is pulled upward. The connecting rotating plate 63 is rotatably connected to the support plate on the upper surface of the inclined rotating plate 64. The connecting rotating plate 63 applies an upward lifting force to the inclined rotating plate 64, causing the inclined rotating plate 64 to rotate counterclockwise. Through the movement of the sliding column 65 in the sliding groove 66, an upward pushing force is applied to the lifting support plate 61. The lifting support plate 61 pushes the data acquisition sensor 4 out of the protective rubber pad 5, making it easy to quickly remove the data acquisition sensor 4 and speeding up the laying speed of the acquisition device. After the laying is completed, the data acquisition sensor 4 is used to collect detection data, and the collected data is received by the data receiver 3.
