The invention discloses a spring-adjusted automatic docking air supply device. The spring-adjusted automatic docking air supply device comprises a transmitting mechanism, a receiving mechanism and a mounting bracket, wherein receiving mechanism and the transmitting mechanism both adopt knuckle bearings and therefore can deflect by a certain angle, so that the transmitting mechanism and the receiving mechanism can still work normally under the complicated work conditions that the axes are not aligned in the initial state; a guiding conical mouth adopts a bell mouth and a linear guiding hole, so that the receiving capability of the receiving mechanism is stronger; the linear guiding hole can correct deflection of the transmitting mechanism to enable the axes of the transmitting mechanism and the receiving mechanism to be collinear; a positioning spring and a positioning spring adjustment hanging block are mounted in each of the transmitting mechanism and the receiving mechanism, so that the adjustment is more convenient; and the transmitting mechanism, as well as the receiving mechanism, adopts linear contact between a steel ball and a valve opening for sealing, so that the sealing effect is good. The spring-adjusted automatic docking air supply device eliminates potential safety hazards of workers in high-risk complicated environments, the production automation and the object transport automation are improved, and the production cost is lowered.

A photoelectric composite geophone (1), comprising a housing (101), an optical fiber detection assembly (102) and a piezoelectric detection assembly (103). The optical fiber detection assembly (102) comprises a first compliant cylinder (1021) and a second compliant cylinder (1022), which are coaxially arranged, and a first optical fiber (1023) fixedly wound around the first compliant cylinder (1021) in a clockwise manner, and a second optical fiber (1024) fixedly wound around the second compliant cylinder (1022) in an anticlockwise manner. The piezoelectric detection assembly (103) is located between a lower end face of the first compliant cylinder (1021) and an upper end face of the second compliant cylinder (1022), and comprises a detection base (1031), a first piezoelectric piece (1032) fixedly arranged on an upper surface of the detection base (1031), a second piezoelectric piece (1033) fixedly arranged on a lower surface of the detection base (1031), and an electrical signal transmission line (1034) electrically connected to the first piezoelectric piece (1032) and the second piezoelectric piece (1033). By means of simultaneous measurement of seismic waves by combining the optical fiber detection assembly (102) with the piezoelectric detection assembly (103), the photoelectric composite geophone (1) can more accurately obtain an actual parameter of a vibration signal and has higher accuracy and credibility.
