Embodiment
[0022] see figure 1 , the present invention provides a marine riser detection transportation device, which mainly includes two parts: a reciprocating unit 1 installed at the starting position of the riser detection and a transportation body 2, wherein the shape of the transportation body 2 is similar to a cylinder, and the whole cylinder is divided into two parts Two halves, one side is connected by hinge 21, and the other side is connected by hasp switch 22, and hasp switch 22 can adopt existing structure, can get final product to opening and locking two half cylinders, and installation and dismounting are very easy. When the conveyor main body 2 is installed, it is only necessary to open the hasp switch 22, and the two semi-cylinders can rotate around the hinge shaft until the opening is larger than the diameter of the standpipe 10, and then the conveyor main body 2 can freely pass through the barrier installed on the inner wall of the cylinder. The cross runner 3 is install...

The invention discloses a marine riser detection and conveying device, which comprises a conveying main body, at least three cross runners and a reciprocating motion unit, wherein the conveying main body comprises two semi-circular shells with one sides being hinged in the axial direction and the other sides being provided with hasp switches; the cross runners comprise stepped shafts, connecting sleeves capable of being arranged on the stepped shafts in a rotating manner, and radially elastic clamping wheels connected to the connecting sleeves; the two ends of the stepped shafts are arranged on the inner walls of the semi-circular shells; the reciprocating motion unit comprises a guide pipe, a ball receiving switch and a ball throwing switch; the guide pipe is positioned at a detection starting position and used for accommodating counterweight balls therein; the ball receiving switch is arranged on the guide pipe and emerges from the water under the action of the ball throwing switch to automatically receive one counterweight ball and sending the counterweight ball into the ball throwing switch; the ball throwing switch is arranged on the conveying main body, and runs to the bottom of the sea under the gravity action of the received counterweight ball to automatically throw the counterweight ball; and under the action of buoyant force, the ball receiving switch is pushed up to continuously receive the next counterweight ball.
Description
technical field [0001] The invention relates to marine riser detection technology, in particular to a marine riser detection, detection, transportation device and detection system. Background technique [0002] The marine riser is the pipeline connecting the seabed and the floating body on the sea surface, and its main function is to transport oil or natural gas; as a transmission pipeline connecting the underwater production system and the floating structure, it is an important part of the deep-sea oil and gas field development system. Due to the time-varying nature of deep-water marine environmental loads and the complexity of the interaction between the riser and the seabed soil, the in-place safety of the riser has unique challenges and obvious uncertainties. Once a failure occurs, the safety of the entire oil production system will be jeopardized , and even lead to a series of serious accidents. If there is a set of devices that can detect and solve faults before riser...
