Embodiment 1

[0065] An ROV-based underwater equipment retracting device includes an ROV-end connecting part and an equipment-end connecting part. The connecting part at the ROV end is connected to the ROV load-bearing frame through bolts, etc., and transmits the lifting weight to the main lifting point of the ROV body, and has the function of combining and locking the lifting points. The connecting part of the equipment end is connected with the load-bearing part of the top center of the equipment body through the welding process, and has the function of combining lifting points. The overall installation is shown as figure 1 shown.

[0066] The connecting part of the ROV end consists of a main frame 1, two lifting columns 2, a guide body 3, an underwater docking camera 4, a support body 5, a locking cylinder 6, a connecting body 7, a contact sensor 8, two lock shafts 9 and two The guide body 3 is generally made of nylon material, which is connected with the lifting column 2 and has a gui...

Embodiment 2

[0076] According to the device of embodiment 1, the steps of the underwater equipment deployment method are as follows:

[0077] Step 1: Operate the ROV deployment crane system to lift the ROV from the deck to the deployment height; install the connecting parts of the ROV end to the load-bearing part of the ROV chassis as a whole through bolts, etc.

[0078] Step 2: Connect the inlet and outlet ports of the locking cylinder 6 to the valve box of the ROV operation tool through the high-pressure oil pipe, retract the telescopic rod of the locking cylinder 6 through the ROV console; connect the underwater docking camera 4 and the contact sensor 8 Connect to the reserved interface of the ROV electrical interface box through a watertight cable, and display the monitoring screen on the monitor.

[0079]Step 3: Move the underwater equipment to be deployed under the ROV, operate the ROV deployment crane to move the horizontal position of the ROV, and connect the connecting parts at th...

Embodiment 3

[0085] According to the device of embodiment 1, the underwater equipment recovery method steps are as follows:

[0086] Step 1: Lift the ROV from the deck to the deployment height by operating the deployment crane system of the ROV; install the connecting parts of the ROV end to the bearing part of the chassis of the ROV through bolts, and get ready;

[0087] Step 2: Connect the oil inlet and oil return port of the locking cylinder 6 to the valve box of the ROV's operation tool through the high-pressure oil pipe, and retract the telescopic rod of the locking cylinder 6 through the console of the ROV; The camera 4 and the contact sensor 8 are connected to the reserved interface of the electrical interface box of the ROV through a watertight cable to obtain a monitoring picture;

[0088] Step 3: Deploy the ROV into the water, fly to its vicinity according to the precise longitude and latitude when the underwater equipment is deployed, turn on the underwater docking camera 4, obt...

Abstract

The invention discloses an underwater equipment deploying and retracting device, a laying method and a recycling method based on an ROV, which is used for achieving butt joint and locking of underwater equipment and an operation type remote operated vehicle (ROV) body and completing deploying and retracting of the underwater equipment by controlling the ROV. The device comprises an ROV end connecting component and an equipment end connecting component, wherein the ROV end connecting component is connected with the ROV body, and the equipment end connecting component is connected with the underwater equipment; when the device is used for laying the underwater equipment, the ROV end connecting component and the equipment end connecting component are in butt joint and locked on a deck to forma combined body, the combined body is laid to a seabed mounting point by laying the ROV body, and the laying of the underwater equipment is completed by unlocking the device; when the device is usedfor recycling the underwater equipment, the ROV end connecting component and the equipment end connecting component are in butt joint and locked at the seabed to form a combined body, the combined body is recycled to the deck by recycling the ROV body, and the underwater equipment is recycling by unlocking the device.

Description

technical field [0001] The invention relates to the technical field of seabed observation equipment and seabed observation network, in particular to an ROV-based underwater equipment retracting device, deploying and recovering method. Background technique [0002] The seabed observation network is an open ocean comprehensive observation system formed by interconnecting a series of ocean observation instruments and land-based information processing equipment by using submarine photoelectric composite cables and wireless acoustic communication. The underwater part of the submarine observation network usually includes underwater equipment such as the main submarine base station, junction box, and scientific observation platform. [0003] The conventional retraction method of the underwater equipment of the seabed observation network is completed through the cooperation of the ship-borne hoisting equipment and ROV. When deploying, use the gantry crane to hoist the underwater eq...
