To more specifically illustrate the principle of the driving device provided by the embodiments of the present invention to realize one-time measurement of data at multiple positions in a hole, the following description is exemplified by using seismic exploration to obtain geological parameters:

In some embodiments, as shown in fig. 3, the transmission 6 connects the driving part 22 and the motion sensing element 31 to convert the rotational motion of the driving part 22 into a linear motion and to drive the motion sensing element 31 into a linear motion. For example, the transmission device 6 is a rack-and-pinion mechanism, a pinion is fixed to the driving member 22 and rotates under the driving of the driving member 22, a rack performs a linear motion under the driving of the pinion, the motion sensor element 31 is fixed to the rack, and the motion sensor element 31 performs a linear motion under the driving of the rack.

Further, as shown in fig. 4, the transmission device 6 is a transmission device in a screw transmission form, and the screw transmission is a mechanical transmission for realizing conversion between rotary motion and linear motion by screwing a screw and a thread tooth surface. Specifically, the transmission 6 includes a screw 61 and a slide table 62. The screw 61 is fixed with the driving part 22, the sliding table 62 is sleeved outside the screw 61 and is matched with the screw thread of the screw 61 to form a transmission device in a spiral transmission mode, and the sliding table 62 is driven by the screw 61 to perform linear motion. The motion sensor element 31 is fixed to the slide table 62, and the slide table 62 drives the motion sensor element 31 to perform linear motion. Specifically, the sliding table 62 is provided with a threaded hole, and the sliding table 62 is sleeved outside the screw 61 through the threaded hole. The internal thread of the threaded hole is matched with the external thread of the screw rod 61, the screw rod 61 and the sliding table 62 form a spiral transmission device, and one end of the screw rod 61 is connected with the driving part 22 through the coupler 7 and rotates under the driving of the driving part 22. Under the interaction between the external threads of the screw 61 and the internal threads of the threaded hole of the slide table 62, the slide table 62 moves linearly in the length direction of the screw 61.

In some embodiments, as shown in fig. 4, the measuring device further includes a limiting member 8, the limiting member 8 is fixed to the fixing member 1, one end of the screw 61 is connected to the driving member 22, the other end of the screw 61 is provided with the limiting member 8, and when the sliding table 62 moves to the other end of the screw 61, the limiting member 8 prevents the sliding table 62 from moving continuously, so as to prevent the sliding table 62 from falling off the screw 61.

In some embodiments, as shown in fig. 4, the measuring device further includes a guide rail 9, the guide rail 9 is fixed to the fixing member 1, and a length direction of the guide rail 9 is parallel to a length direction of the screw 61. As shown in fig. 5, the slide table 62 is provided with a guide rail groove 63, the guide rail 9 is positioned in the guide rail groove 63, and the interaction force between the guide rail 9 and the guide rail groove 63 restricts the rotation of the slide table 6 around the axis of the screw 61, so that the slide table 62 can only move linearly along the length direction of the screw 61 under the driving of the screw 61.

The screw pitch of the screw 61 is uniform, and the movement distance of the slide table 62 can be accurately controlled by controlling the rotation angle of the screw 61, thereby accurately controlling the displacement of the movement sensing element 31 fixed to the slide table 62. Specifically, the relationship between the displacement of the slide table 62 and the rotation angle of the screw 61 is:

where s is the displacement of the slide table 62, d is the pitch of the screw 61, and θ is the rotational angle of the screw.

Meanwhile, considering that the measuring device measures in the drill hole, the internal space of the drill hole is limited, and the control of the overall size of the measuring device is of great importance. Compared with a transmission device in the form of a gear rack and the like, the transmission device in the form of a screw transmission can improve the control precision of the displacement of the motion sensing element 31 on the premise of not increasing the size of the measuring device.

Taking a transmission device in a size rack form as an example, on the premise that the control accuracy of the rotation angle output by the driving device 2 is not changed, the larger the number of teeth of the gear is, the higher the control accuracy of the displacement of the motion sensing element 31 is, while the diameter of the reference circle of the gear is proportional to the number of teeth of the gear, the larger the number of teeth of the gear is, the larger the size of the gear is, and in order to improve the control accuracy of the displacement of the motion sensing element 31, the size of the gear needs to be increased, and further the whole size of the measuring device.

However, in the case of the screw-type transmission 6, on the premise that the control accuracy of the rotational angle output from the driving device 2 is not changed, the smaller the pitch of the screw 61, the higher the control accuracy of the displacement of the motion sensor element 31, and the smaller the pitch of the screw 61, the smaller the size of the screw, and the larger the size of the entire measuring device.

In some embodiments, the driving device 2 is a stepping motor, and the control accuracy of the displacement of the motion sensor element 31 is further improved by precisely driving the rotation angle of the screw 61 by the stepping motor.
