The body support 13 is supported on the base 14, and the above-mentioned medium inlet section and each leakage plugging training pipe section are supported by the body support 13.

[0074] In this embodiment, the material of the support 13 is an angle steel of 75*75*5mm, and the fixed support method is welding.

[0075] At each of the four corners above the base 14, there is designed one lifting lug 1401 with an allowable load of 3.25T.

The leakage points include but are not limited to drilling small holes, cutting cracks, welding defects, using damaged ball valve packing, etc.

[0081] When in use, the medium is injected into the system through the quick connector 101 of the medium inlet section.

The positions of the leakage points can be planned in advance according to the training requirements.

[0084] After the training is completed, if the medium is liquid, it is necessary to open the second valve 802 of the drain port of the basket filter plugging training pipe section 8, the fourth valve 1002 of the drain port of the square atmospheric pressure storage tank plugging training pipe section 10, and the sixth valve 1102 of the drain port of the cylindrical pressure storage tank plugging training pipe section 11 to drain the liquid medium in the system.

[0085] During the training process, leaked and emptied liquid is collected on the base 14 and directed out through a hose connected to the drain pipe 1404 to avoid contamination.

[0086] After the training is completed, the device can be transferred to the lifting area with the help of a hydraulic vehicle, and then lifted to other decks for storage by a crane, or transported to other offshore platforms for training.

[0087] According to the above scheme of the utility model, the utility model does not need to set up power components such as water tanks and water pumps. It only needs to be connected to the fresh water, hot water, factory air, etc. of the offshore platform public station through a quick connector to achieve the filling and replenishment of the medium.

[0088] The utility model can not only carry out plugging training for liquid leakage, but also carry out plugging training for gas and gas-liquid mixed medium.

[0089] This utility model focuses on the training of welds, elbows, tees, reducers, pipe caps, filters, storage tanks, valve bodies, valve packings and other positions of offshore platform oil, gas and water treatment pipelines. It is more comprehensive and targeted.

[0090] The utility model is specially used for on-site training of offshore platforms, and can realize the dragging and transfer of the device by a hydraulic vehicle and the transportation of the crane between platforms.

[0091] The utility model is used for offshore platform operators to carry out targeted plugging training for different pipeline positions, thereby improving the plugging skills of the front-line personnel.

[0092] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
