Example 1
The embodiment provides a walking system of a submarine drilling rig, as shown in fig. 1, comprising: loading platform 1, spliced pole 2, flotation tank 3, supporting legs 4, power device 5 and positioner.
The loading platform 1 is connected with the buoyancy tank 3 through a connecting column 2, and the loading platform 1 is used for loading a drilling device of a submarine drilling rig. The connecting columns 2 are selected to be in proper number according to the size of the loading platform 1 so as to achieve stable connection. Preferably, the number of the connecting columns is more than 4, and as shown in fig. 1, the number of the connecting columns 2 is 4, and the connecting columns are respectively connected to four corners of the rectangle of the loading platform 1.
The buoyancy tank 3 comprises a water charging and discharging device for discharging water through the buoyancy tank 3 to lift the walking system of the subsea drilling machine or sucking water through the buoyancy tank 3 to lower the walking system of the subsea drilling machine. The buoyancy tank 3 may be an integrated buoyancy tank, and the water is filled and drained by the integrated buoyancy tank. Preferably, the buoyancy tank 3 includes at least two small buoyancy tanks working independently, each of which can be operated by filling and draining water independently, so that the loading platform 1 can move slightly obliquely, avoid obstacles, or correct the inclination of the walking system of the seafloor drilling rig caused by the influence of the complex ocean environment such as ocean currents. As shown in fig. 1, the buoyancy tank 3 includes two small buoyancy tanks working independently, which are respectively located at the left and right sides below the loading platform 1, and each small buoyancy tank is connected with 2 connecting columns 2 to connect with the loading platform 1. By controlling the water suction and drainage amount, the submarine drilling machine can be controlled to slowly descend and ascend, and the moving precision is improved.
A power device 5 is loaded on the connecting column 2 and used for pushing the walking system of the submarine drilling rig to move when the walking system of the submarine drilling rig is in a floating state so as to reach a target area. The movement here refers to the movement due to the forward, backward, leftward and rightward directions (positive and negative x-axis and y-axis directions as shown in fig. 1) of the propulsion force, and the movement due to the forward, backward, leftward and rightward directions of the propulsion force and the filling and draining of the buoyancy tank.
Preferably, the power plant 5 comprises, but is not limited to, a propeller plant. As shown in fig. 2, the propeller arrangement comprises a forward propulsion propeller arrangement 51, a backward propulsion propeller arrangement 52, a left propulsion propeller arrangement 53 and a right propulsion propeller arrangement 54. The forward propulsion propeller device 51, the backward propulsion propeller device 52, the leftward propulsion propeller device 53 and the rightward propulsion propeller device 54 are respectively arranged on different outer side surfaces of the connecting column 2, as shown in fig. 2, the four groups of propeller devices 51, 52, 53 and 54 are all arranged on the outer side surface of the connecting column 2, so that water flow is not blocked during propulsion, and the propulsion efficiency is improved. Two forward propulsion propeller devices 51 are respectively installed on the left side surface and the right side surface of the left front and right front connection columns 2 for performing forward propulsion motion control, two backward propulsion propeller devices 52 are respectively installed on the left side surface and the right side surface of the left rear and right rear connection columns 2 for performing backward propulsion motion control, two leftward propulsion propeller devices 53 are respectively installed on the front side surface and the rear side surface of the left front and left rear connection columns 2 for performing leftward propulsion motion control, and two rightward propulsion propeller devices 54 are respectively installed on the front side surface and the rear side surface of the right front and right rear connection columns 2 for performing rightward propulsion motion control. And two propeller devices in each group can ensure the stable operation of translational propulsion, realize the turning movement control with angles and improve the flexibility of the propulsion movement of the power device. Preferably, walking control of the power device and positioning of the positioning device are adopted, and two moving modes of coarse adjustment and fine adjustment are adopted, wherein the coarse adjustment is realized by controlling the propeller device to realize large-displacement walking of the submarine drilling machine and move to a target drilling area; and then fine adjustment is carried out, namely, the propeller device is controlled to move in a micro displacement mode, so that the submarine drilling machine can find the well drilling position accurately.
The supporting feet 4 are connected and positioned at the bottom of the buoyancy tank 3 and used for standing up the buoyancy tank 3 and sitting on the seabed ground. As shown in fig. 1, four supporting legs 4 are connected to the bottom of the buoyancy tank, which play a role in supporting the working platform and reducing the contact with the sediment on the seabed, so that when the buoyancy tank drains water and rises, the friction force generated by the contact of the sediment and the bottom buoyancy tank can be effectively reduced, and the problem of adhesion force generated by the buoyancy tank and the sediment on the seabed is solved.
Preferably, the support feet 4 are connected to the buoyancy tank 3 in a manner allowing relative movement. The supporting legs 4 and the buoyancy tank 3 can move relatively to adapt to different seabed conditions, and the relative movement mode can be realized through a gear rack or hydraulic pressure mode and the like.
Preferably, the support feet 4 comprise telescopic means for adjusting the length of the support feet 4 to accommodate uneven seabed ground, keeping the loading platform level.

According to the submarine drilling rig walking system, the floating box is used for draining water, the submarine drilling rig is lifted, the submarine drilling rig is moved to a target area through the power device, then the floating box is used for absorbing water, the submarine drilling rig is lowered and is located in the target area, and walking under the sea is achieved. The traveling device can accurately reach a target area and automatically move to the next working place, and has the advantages of flexible movement, high precision, more convenient operation, stronger applicability and wider practical range. Meanwhile, the cost required in the process of dismounting and mounting of the traditional submarine drilling machine and hoisting of the floating crane is saved, and the cost can be greatly reduced.
