[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] A pipe-laying vessel applicable to the beach and sea (hereinafter referred to as the pipe-laying vessel), referring to 1- Figure 2, the main body is composed of a hull assembly 100, a hoisting assembly 300, and a plow head assembly 200. The hull assembly 100 serves as the installation carrier for the hoisting assembly 300 and the plow head assembly 200. The movement of the hull assembly 100 drives the plow head assembly 200 to perform trenching and backfilling operations, and the pipe-laying operation is achieved through the coordinated action of the hoisting assembly 300 and the plow head assembly 200. Specifically, the main body of the hull assembly 100 consists of a hull member 101, a wheel structure 107, and a lifting structure 112. The wheel structure 107 is assembled on the hull member 101 and serves as the support and moving carrier for the hull member 101. Correspondingly, the lifting structure 112 is assembled on the wheel structure 107 and is configured to be able to drive the hull member 101 to lift, so as to control the height of the hull member 101 and the plow head assembly 200. Back to Figure 1 and 2 , continue to describe the pipe-laying ship. The hull member 101 has a first end 101a and a second end 101b in the first direction. The first end 101a is configured as the tail end of the hull member 101. Correspondingly, the plow head assembly 200 is assembled at the first end 101a of the hull member 101. In some embodiments, the plow head assembly 200 includes a plate member 201 and a plurality of plow head members 202. The plurality of plow head members 202 are assembled on the plate member 201 and perform trenching and backfilling operations as the hull member 101 moves. At the same time, the lifting of the plow head assembly 200 is synchronized with the lifting of the hull member 101, that is, the operating height of the plow head assembly 200 can be controlled through the lifting structure 112 to achieve the control of the trenching depth. In some embodiments, the plate member 201 includes an installation portion 201a connected to the hull member 101 and a main body portion 201b extending to the outer end of the hull member 101. The lower surface of the main body portion 201b is configured as the installation surface of the plow head member 202, and the end of the main body portion 201b away from the installation portion 201a is configured to be inclined downward, that is, the height of the end of the main body portion 201b away from the hull member 101 is less than the height of the end adjacent to the hull member 101. In some embodiments, the plurality of plow head members 202 are arranged in a linear array on the lower surface of the main body portion 201b. Exemplarily, two sets of plow head groups are provided on the plate member 201. A single set of plow head groups includes a plurality of plow head members 202 spaced along the length direction of the main body portion 201b, and the two sets of plow head groups are spaced in the width direction of the main body portion 201b. Back to Figure 1 and 2, continue to describe the pipe-laying vessel. The above-mentioned hoisting assembly 300 includes a seat member 301 and a bracket member 302. The bracket member 302 is assembled on the base member and configured to be able to rotate around the axis of the seat member 301. At the same time, the hoisting assembly 300 further includes a hook member 304, which is connected to the bracket member 302 through a rope 303 and can realize the lifting and lowering of the hook member 304 through the retraction and release of the rope 303. Further, a placement structure 400 is also provided on the hull member 101. The placement structure 400 is configured to be able to accommodate the pipe conveyed by the hoisting assembly 300. The pipe is placed on the placement structure 400 in a manner extending along the length direction of the hull member 101 and is configured to be able to slide from the placement structure 400 into the trench pre-dug by the plow head assembly 200 during the movement of the bow member. In some embodiments, the placement structure 400 includes a plurality of roller members 401. The plurality of roller members 401 are arranged at intervals along the length direction of the pipe-laying vessel, and a single roller member 401 is configured to be able to rotate around its own axis. During the pipe-laying operation, the pipe is transported to the roller member 401 by the hoisting assembly 300. During the movement of the hull member 101, the pipe moves in the opposite direction of the movement direction of the hull member 101 on the roller member 401 and falls into the trench to complete the pipe-laying operation.

[0032] During the operation of the pipe-laying vessel, when the pipe-laying vessel reaches the designated pipe-laying location, the hull member is lowered through the lifting structure, so that the plow head member is lowered and digs a trench deep into the beach bottom. The pipeline is lifted by the crane assembly and placed on the placement structure. As the hull member moves, the pipe slides on the rollers and thus slides into the trench dug by the plow head. Since the structure of the plow head can achieve backfilling after digging, the pipeline can be smoothly laid.

[0033] First embodiment of the hull assembly 100:

[0034] Refer to Figure 3In this embodiment, the hull structure 101 is configured as an air cushion vehicle and includes a hull portion 103 and an air cushion portion 104, wherein the air cushion portion 104 is configured to be filled with gas and float on the surface of the water body, and the hull portion 103 is configured as an installation carrier of the wheel structure 107, the hoisting assembly 300 and the plowshare assembly 200. Specifically, the wheel structure 107 includes at least four wheel components 111 distributed at the four corners of the hull structure 101, and correspondingly, the lifting structure 112 is configured as a hydraulic cylinder body 113 connecting the wheel component 111 and the hull portion 103. The liquid cylinder body is assembled on the hull part 103, and the output end of the hydraulic cylinder body 113 is connected to the wheel body component 111, and the hydraulic cylinder body 113 is tilted. The lifting and lowering of the hull frame and the plowshare assembly 200 are realized by the extension and retraction of the output end of the hydraulic cylinder body 113. At this time, during the movement of the hull component, when the hull component advances to a relatively deep mudflat, the piston rod of the hydraulic cylinder body slowly rises with the water depth, and the distance between the wheel body structure and the bottom surface of the hull component increases, so that the bottom of the hovercraft can always be kept higher than the mudflat water surface, the friction force encountered during the forward movement is small, and the air cushion part can be prevented from being damaged.

[0035] Embodiment 2 of the hull assembly 100:

The first wheel group 108 and the second wheel group 109 are arranged at intervals along the length direction of the hull member 101 and cooperate to achieve the support and movement of the hull member 101. Both the first wheel group and the second wheel group 109 include a first shaft body 110 extending along the width direction of the hull member 101 and wheel body members 111 assembled at both ends of the first shaft body 110. Corresponding to the wheel structure 107, that is, the first wheel group 108 is arranged adjacent to the first end 101a of the hull member 101, and the second wheel group 109 is arranged adjacent to the second end 101b of the hull member 101. The above-mentioned lifting structure 112 is assembled on the first wheel group 108. Exemplarily, the lifting structure 112 is configured as a hydraulic cylinder body 113. The hydraulic cylinder body 113 is assembled on the shaft of the first wheel group 108, and the output end of the hydraulic cylinder body 113 is connected to the subsequent ship body 105. Correspondingly, the above-mentioned hull member 101 includes a ship body 105 and a driving structure 106. Among them, the driving structure 106 is assembled on the first wheel group 108, and the plow head assembly 200 is assembled at the first end 101a of the ship body 105. And the first end 101a of the ship body 105 is configured to be able to rotate around the second end 101b under the action of the lifting structure 112, so as to realize the height adjustment of the plow head assembly 200. Exemplarily, the above-mentioned driving structure 106 includes a box structure. Structures such as a motor and a transmission are provided inside the box structure to drive the second wheel group 109 to rotate to realize the movement of the pipe-laying ship. At the same time, the box structure and the ship body 105 are rotationally connected through components such as a second shaft body 114 to realize the support of the ship body 105 and allow it to rotate around the first end 101a.
