Penetrating method of self-adjusting hydraulic static penetrating device suitable for seabed slope area

A penetrating method of a self-adjusting hydraulic static penetrating device suitable for a land slope area, wherein

• the self-adjusting hydraulic static penetrating device suitable for the land slope area comprises an upper adjustable injection platform and a lower adjustable supporting platform, wherein
• the upper adjustable injection platform is fixedly arranged on the lower adjustable supporting platform;
• the upper adjustable injection platform comprises a rack, a control cabin, a penetrating mechanism, a hydraulic station, a balance weight and first jacks;
• the control cabin, the penetrating mechanism, the hydraulic station, the balance weight and the first jacks are all arranged on the rack;
• the four first jacks are installed at a bottom of a steel structure frame, and the first jacks are fixed to the lower adjustable supporting platform;
• the penetrating mechanism comprises a supporting frame, a plurality of groups of pulleys, a feeler lever, a movable mechanical clamping hand, a fixed mechanical clamping hand and an oil cylinder, wherein
• the plurality of groups of the pulleys, the feeler lever, the movable mechanical clamping hand, the fixed mechanical clamping hand and the oil cylinder are all arranged on the supporting frame;
• the fixed mechanical clamping hand is fixedly arranged on a lower part of the supporting frame;
• the movable mechanical clamping hand is positioned above the fixed mechanical clamping hand;
• slide rails in a vertical direction are arranged at two sides of the movable mechanical clamping hand;
• the slide rails are fixedly arranged on the supporting frame;
• the movable mechanical clamping hand is connected with the oil cylinder through a steel wire;
• the movable mechanical clamping hand moves vertically along the slide rails;
• a feeler lever guide sleeve is arranged on a bottom of the supporting frame;
• the feeler lever sequentially passes through the feeler lever guide sleeve, the fixed mechanical clamping hand and the movable mechanical clamping hand;
• and
• a first gyroscope is fixedly arranged on a top of the balance weight;
• the lower adjustable supporting platform comprises a housing and second jacks, wherein
• a hole allowing the feeler lever to pass through is formed in a middle of the housing;
• the second jacks are respectively arranged at four corners of a bottom of the housing;
• and
• a second gyroscope is arranged in the lower adjustable supporting platform;
• wherein, the penetrating method comprises the following steps:
• step 1, putting the self-adjusting hydraulic static penetrating device into seawater, and dropping the self-adjusting hydraulic static penetrating device on a seabed surface:
• putting the self-adjusting hydraulic static penetrating device into seawater through a rope and dropping the self-adjusting hydraulic static penetrating device onto the seabed surface, transmitting a posture condition, on the seabed surface, of the self-adjusting hydraulic static penetrating device through the second gyroscope, thereby obtaining an angle of a seabed slope;
• step 2, adjusting heights of the first jacks and the second jacks to allow the feeler lever to penetrate into a stratum in a vertical direction or at an angle perpendicular to the seabed surface:
• respectively calculating to-be-lifted heights of the four second jacks according to the angle of the seabed slope obtained in step 1 while the feeler lever needs to penetrate into the stratum in the vertical direction, to guarantee that the lower adjustable supporting platform is in a horizontal state;
• setting the angle of the seabed slope to be α, setting a height of the lower adjustable supporting platform to be h1, setting a length of the lower adjustable supporting platform to be a, setting a height of the upper adjustable penetrating platform to be h2, setting a length of the upper adjustable penetrating platform to be b, and lifting two second jacks at low positions by √{square root over ((a cos α−a)2+(a sin α)2)} while the lower adjustable supporting platform is in the horizontal state;
• when the feeler lever needs to penetrate into the stratum at the angle perpendicular to the seabed surface, lifting the two second jacks at the low positions by √{square root over ((a cos α−a)2+(a sin α)2)}, lifting two first jacks towards a high position of the seabed surface by
