[0019] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, the present invention provides a stop device for a submersible pump on an offshore platform, comprising a stop truss assembly 5, which includes a truss IV, a rotating sleeve V, and a rotating sleeve of the rotating sleeve V fixedly connected to one end of the truss IV. It also includes a truss slide plate assembly 3, which includes two upright plates I, which are fixed parallel to each other on the deck of the offshore platform. Each upright plate has a slide groove II with a certain stroke. A shaft plate III is perpendicular to the two upright plates I at one end, fixing the two upright plates I in place. The stop truss assembly 5 is connected to the truss slide plate assembly 3 through the cooperation of the spindle of the rotating sleeve V with the slide groove II. A bushing is provided on the shaft plate III, and a push screw 2, threadedly engaged with the bushing, passes through the shaft plate III and is fixedly connected to the rotating sleeve of the rotating sleeve V. During operation, under the lifting of the crane, the submersible pump determines its position height based on the changes in the platform's height above the sea surface and the depth of its descent during different sea conditions. Once the submersible pump reaches the appropriate height, the propulsion screw 2 is manually rotated to push the stop truss assembly 5 (truss IV, rotating shaft V) forward through groove II of the truss slide plate assembly 3 on both sides, clamping the submersible pump pipe and freeing it from the long-term load of the crane. This allows the submersible pump to operate normally under different sea conditions. When the position height needs to be adjusted, the propulsion screw 2 is manually rotated in the opposite direction to push the stop truss assembly 5 (truss IV, rotating shaft V) back through groove II of the truss slide plate assembly 3 on both sides, releasing the clamp on the submersible pump pipe. Under the lifting of the crane, the submersible pump can then readjust its position height. When the stop truss assembly 5 is not in operation, it is lifted from one end of the outside by a manual hoist. At this time, the stop truss assembly 5 is rotated upward by rotating the sleeve V, and the bottom is uncovered, so that the anti-corrosion paint can be applied. After the paint is applied, the stop truss assembly 5 is rotated downward by a manual hoist and placed on the deck of the offshore platform.

[0021] Specifically, the push screw 2 is fixedly connected to the rotating sleeve of the rotating sleeve V through the movable sleeve VI. The end of the push screw 2 is equipped with the movable sleeve VI, so that it can flexibly push the stop truss assembly 5 without getting stuck.

[0022] Specifically, the slide groove II is oval in shape, which allows for a good range of adjustment in the horizontal direction.

[0023] Specifically, a limiting and fixing plate 4 is provided to fix the truss IV on the deck of the offshore platform. The limiting and fixing plate 4 is fixed to prevent the truss from moving and deviating from its position.

[0024] Specifically, a rotating handle 1 is fixedly provided on one side of the push screw 2 to facilitate labor-saving operation by the operator.

[0025] Specifically, the two upright plates I are fixed to the deck of the offshore platform by welding. Welding can form a larger contact area on the joint surface, thus providing better strength and seismic resistance.

[0026] Specifically, the limiting and fixing plate 4 is fixed to the truss IV on the deck by welding. Welding can form a larger contact area on the connection surface, thereby providing better firmness and seismic resistance.

[0027] Specifically, the spindle of the rotating sleeve V is provided with rolling bearings at both ends. Through the cooperation of the rolling bearings with the slide groove II, it is connected to the truss slide plate assembly 3. The rolling bearings can protect the spindle of the rotating sleeve V and the slide groove II, making it convenient for operators to operate with less effort.

[0028] The above description is merely an exemplary embodiment of this application and is not intended to limit the scope of protection of this application. The scope of protection of this application is determined by the appended claims.
