The invention belongs to the technical fields of basic engineering such as transportation, municipal administration, water conservancy, and construction. A wire brush drill bit rotary drilling rig and a method for solving buried drills, dropped drills, and stuck drills, including auxiliary walking and transportation equipment, a drill frame, a rotary well frame, a power mechanism, a hollow drill pipe, and a wire brush drill bit. The brush drill bit includes a solid drill rod and wire brushes fixedly distributed on the solid drill rod. The wire brush includes a wire brush body fixedly connected with the solid drill rod and steel wires embedded in the wire brush body. According to the drilling depth, the wear, deformation and bending of the wire brush drill bit during the drilling process, the present invention can effectively analyze and draw the offset and reverse direction of the drill bit accurately, which is convenient for lifting and fishing, and greatly improves the overall The salvage efficiency greatly reduces the difficulty of salvage, and can be applied to the occurrence of various accident situations, which has good promotional significance.

The invention discloses a salvaging tool and a salvaging method. The salvaging tool comprises a housing with an opening in bottom, wherein the lower part of the housing is provided with an elastic salvaging claw part which is arranged in a circumferential direction of the housing and capable of opening and closing in a radial direction of the housing; an opening-closing control line which surrounds in the circumferential direction of the elastic salvaging claw part is arranged on the inner part of the elastic salvaging claw part in a penetration mode; a free end of the opening-closing control line is upward along the housing and penetrates through the top of the housing; and the top of the housing is provided with a cable connecting structure. The salvaging tool and the salvaging method disclosed by the invention can realize salvaging various different litters in a salvaging well, so that operation time is saved, construction is simple and cost is low.

The present invention is applicable to the field of marine operations, and provides an auxiliary fishing device for marine engineering. The fishing device includes a clamping mechanism, and the clamping mechanism includes two clamping parts; a displacement mechanism, and the displacement mechanism includes two displacement parts. , the two displacement parts are driven by forward and reverse servo motors, and the two displacement parts are respectively used to adjust the positions of the two moving seats. The fishing device provided by the present invention adjusts the position of the moving seat through the displacement member, that is, adjusts the position of a single clamping member, so that the distance between the two clamping members can be adjusted to meet the requirements for salvaged objects of different sizes. Grabbing, and the adjusted mobile seat does not affect the realization process of the clamping part on the salvage. The present invention also provides an auxiliary fishing method for ocean engineering, which is realized by the above-mentioned auxiliary fishing device for ocean engineering.

The invention discloses a salvage ship for floating objects on the water surface. The salvage ship comprises a ship body as well as an air flotation device, an interception device, a collection device, a power device and a control device which are arranged on the ship body, wherein the air flotation device is used for performing air flotation on floating objects semi-suspended in water to the water surface; the interception device is used for intercepting the floating objects air-floated on the water surface and preventing air-floated floating objects from diffusing; the collection device is used for recovering the floating objects in a centralized manner; the power device is used for supplying power to the salvage ship for acting; the control device is used for performing uniform control on the air flotation device, the interception device, the power device and the collection device. The salvage ship is large in working surface and high in working efficiency and can effectively salvage the floating objects on the water surface.

The invention discloses a static pressure fishing device which comprises an outer tube, an upper slip ring, a lower slip ring and a feeler lever. The upper slip ring is arranged on the upper portion of an inner cavity of the outer tube, the lower slip ring is arranged on the lower portion of an inner cavity of the outer tube, a guide rod is arranged in the lower slip ring, a center cam is arranged on the guide rod in a penetrating mode and can slide up and down along the guide rod, one side of the center cam is meshed with a movable shaft, the rear end of the movable shaft is arranged in mounting holes formed in the lower slip ring and the side wall of the outer tube in a penetrating mode, a connector is assembled at the lower end of the guide rod and can slide up and down on the guide rod, the upper end of the connector can touch the lower end of the center cam to make the center cam separated from the movable shaft, the upper end of the feeler lever is fixed to the lower end of the connector, and a check valve is assembled at the bottom of the outer tube. The static pressure fishing device has the advantage that the problems that in related drilling operation, down-hole junk is difficult to fish, and the fishing objects are limited are thoroughly solved.

The invention relates to a method for salving a deep-buried cable by using a high-pressure water-injection shallow sea burying material washing device, which is characterized in that: firstly,a special rope for salving cables is arranged in a high-pressure spray gun; the end of the rope is connected with a salving anchor chain; the anchor chain is connected with a group of roller type slaving anchors; then the a platform is positioned; the high-pressure water-injection shallow sea burying material washing device is laid according to a laying procedure; a high-pressure heavy-flow water pump is started and provided to the high-pressure water-injection shallow sea burying material washing device to cut the seabed; and the roller type anchor hooks the cable and dragging the cable out of the water surface. The method has he advantages of effectively salving failed cables deeply buried through the development and improvement of functions of the prior equipment, saving cost and solving the problem of salving deep-buried cables.
