In the embodiment, the multi-stage oil cylinder 7 is adopted to replace a probe rod in the traditional static sounding equipment, the characteristics of long working stroke and high penetration force of the multi-stage oil cylinder 7 are fully utilized, and when the probe 10 penetrates underwater, the multi-stage oil cylinder 7 is controlled to act, so that a piston rod of the multi-stage oil cylinder 7 gradually extends underwater, and the continuous penetration operation of the probe 10 can be implemented.
In the process, the continuity of the penetration of the probe 10 can be really realized by only utilizing the characteristic that the multistage oil cylinder 7 can be continuously extended without continuously increasing the traditional probe rod or configuring a complex penetration mechanism for driving the probe rod, thereby not only reducing the labor intensity and improving the operation efficiency, but also ensuring the operation safety.
In the technical scheme, the multi-stage oil cylinder 7 is directly connected with the probe 10 for injection, so that the problem of probe rod slipping is solved, a surface sand layer can be penetrated easily, and the accident that the probe rod is bent or broken when touching a hard sand layer can be effectively avoided.
In this embodiment, the outside of the multi-stage cylinder 7 is also provided with a lifting cylinder composed of two sets of single cylinders 8 and a connecting block 9, and the lifting cylinder mainly has the following functions: 1. the multi-stage oil cylinder 7 is clamped and fixed, and the stability of the multi-stage oil cylinder 7 in the process of penetrating the probe 10 is ensured; 2. when the probe 10 is installed, the lifting oil cylinder can lift the multi-stage oil cylinder 7 upwards, so that the installation part of the probe 10 is positioned inside the equipment cabin, the operation is not required to be carried out at the bottom of the equipment cabin, and the convenience of the operation is greatly improved. 3.

In the present embodiment, the depth detection means functions to detect the penetration depth of the probe 10. The main innovation point of the device lies in that the structural characteristics of the diameter change of the piston rod of the multistage oil cylinder 7 are fully considered, a return mechanism is designed, and the detection wheel 172 and the auxiliary wheel 175 generate continuous radial extrusion force on the piston rod of the multistage oil cylinder 7 through the two supporting rods 173 and the two extension springs 174, so that the piston rod can always generate friction with the detection wheel 172 in the downward extending process, and the accuracy of the detection of the penetration depth of the probe 10 by the rotary encoder 176 is also ensured.

Because the oil tank of underwater operation needs to be sealed, when oil is reduced, vacuum can be formed in the oil tank, if a hard oil tank is adopted, the normal flow of hydraulic oil can be influenced, the oil tank is easily crushed by seawater, and when the oil is increased, high pressure can be formed in the oil tank, so that not only can back pressure of oil backflow be formed, but also the oil tank can be possibly burst.
In this embodiment, an oil tank capable of stretching and retracting along with the change of the oil quantity of hydraulic oil is configured in the equipment bin, so that the influence of the change of the oil on the oil tank is solved. When the oil amount in the oil tank is reduced, the compression spring 151 extends to push the top plate 153 to move downwards so as to compress the oil tank, and since the oil tank is made of flexible material (nitrile rubber, silica gel and the like) and is provided with an annular outward protrusion 154, when the top plate 153 compresses the upper part of the oil tank to deform, the part is gradually compressed to be flat. When the hydraulic oil is injected into the oil tank, the oil tank can be opened again.
In addition, the extension stroke of the multi-stage oil cylinder 7 is long, so that different exploration depth requirements can be met, and the application range of the equipment is further expanded. Meanwhile, after the multi-stage oil cylinder 7 is completely contracted, the axial occupied space of the multi-stage oil cylinder is small, and the multi-stage oil cylinder is suitable for occasions with small installation space.
The multistage oil cylinder 7 is arranged in the center of the whole set of equipment, in the process of downward penetration, the counter force of rock soil borne by the probe 10 is superposed with the gravity center of the equipment on the same straight line, the equipment is jacked and turned over by taking any point as a fulcrum, the stability of the equipment is effectively ensured, and the counter force provided by the self weight of the equipment can be utilized to the maximum extent. If the moment arm of the counterforce exerted by the rock soil is not in the center of the device, the moment arm of the counterforce exerted by the rock soil is larger than that of gravity, so that the stability of the device in the construction process is poor.
In this embodiment, the single cylinder of the lift cylinder is realized by adopting the following structure: the hydraulic control device comprises a piston rod and a cylinder sleeve, wherein two ends of the cylinder sleeve are opened, the cylinder sleeve is sleeved on the piston rod, two oil way holes are formed in the piston rod from the end face inwards and penetrate through the side wall of the piston rod, one end of each oil way hole is correspondingly communicated with an upper oil cavity or a lower oil cavity in the cylinder sleeve, and the other end of each oil way hole is connected with a hydraulic operation valve.
