[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] For examples, see Figure 1-Figure 5 As shown, this embodiment provides a marine oil and gas connector anchoring device, including a fixing sleeve 1, which is fixed to the connector by bolts 14. The fixing sleeve 1 can be annular, and sliders 2 are movably provided on both sides of the fixing sleeve 1. One side of the slider 2 is movably connected to a limiting sleeve 3, and an anchor rod 4 is slidably provided in the limiting sleeve 3. The anchor rod 4 is hammered, and the connector is anchored when the anchor rod 4 is inserted into the seabed soil layer.

[0025] Among them, the limiting grooves 31 are symmetrically opened in the limiting sleeve 3, and the limiting strips 411 are symmetrically arranged on the outer side of the anchor rod 4. The limiting strips 411 are slidably connected with the limiting grooves 31, which can improve the stability of the anchor rod 4 moving downward when being hammered.

[0026] At the same time, a pair of annular edges 11 are arranged on the outside of the fixing sleeve 1, and the slider 2 is slidably connected to the pair of annular edges 11, so the position of the slider 2 can be adjusted according to the required anchoring position, and a plurality of fixing holes 12 are opened on the annular edge 11, and a positioning pin 13 is inserted into the fixing hole 12. The slider 2 is fixed by the positioning pin 13 to improve the stability of the slider 2.

[0027] Since the limiting sleeve 3 can also be rotated according to needs to further anchor the position, the slider 2 and the limiting sleeve 3 are fixed by the positioning pin 21 to ensure the stability of the limiting sleeve 3.

[0028] In order to strengthen the anchoring of the connector, a plurality of through holes 45 are opened on the outer wall of the lower end of the anchor rod 4, and spikes 47 are slidably arranged in the through holes 45. When the anchor rod 4 is inserted into the seabed soil layer, the spikes 47 slide out of the through holes 45 to anchor the connector.

[0029] In order to make the spike 47 slide out of the through hole 45 and insert into the seabed soil layer, a push plate 43 is provided in the anchor rod 4, and the upper end of the push plate 43 is slidably connected to the slide groove 49 opened at the upper end of the anchor rod 4, and the lower end of the push plate 43 is slidably connected to the straight groove 412 opened at the lower end of the anchor rod 4. A plurality of push blocks 44 are provided at the lower end of one side of the anchor rod 4, and the position of the push block 44 corresponds to the position of the spike 47. Therefore, when the push plate 43 slides, the push block 44 pushes the spike 47, so that the spike 47 slides out of the through hole 45, thereby enhancing the anchoring effect.

[0030] A plurality of through holes 42 are provided on the other side of the anchor rod 4. A screw rod 41 is threadedly connected to the through hole 42. One end of the screw rod 41 is in contact with one side of a push plate 43. The screw rod 41 is rotated to push the push plate 43 to move.

[0031] A limiting rod 5 is fixedly arranged on the upper end of the anchor rod 4, and the push plate 43 is slidably connected to the limiting rod 5. When the push plate 43 slides, it is limited by the limiting rod 5, which can improve the stability of the push plate 43.

[0032] In order to prevent the spike 47 from separating from the anchor rod 4, an extension tube 46 is provided on the inner side of the through hole 45. One end of the spike 47 extends out of the extension tube 46. The extension tube 46 has a certain length, which makes the spike 47 more stable. At the same time, a spring 48 is connected between one end of the spike 47 and one end of the extension tube 46. The spring 48 connects the spike 47 and the extension tube 46 to improve the stability of the spike 47.

[0033] When the utility model is used for the anchoring device of the marine oil and gas connector, the fixing sleeve 1 is fixed on the connector, and the position of the slider 2 on the annular edge 11 is adjusted according to the required anchoring position, and the anchor rod 4 is hammered downward to insert the anchor rod 4 into the seabed soil layer to complete the anchoring of the connector. At the same time, the screw rod 41 is rotated to make the screw rod 41 push the push plate 43 to move, and the push block 44 contacts the spike 47 to push the spike 47 out of the anchor rod 4. After the spike 47 is inserted into the seabed soil layer, the anchoring effect of the connector is enhanced.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
