Description

Technical Field

[0001] The invention relates to a torpedo anchor, in particular to a torpedo anchor capable of deepening the anchoring length. Background Art

[0002] In recent years, more and more floating structures (floating docks, floating offshore wind turbines, etc.) have been used for the development of marine resources, transportation of materials and personnel, and construction of offshore islands and reefs. Floating structures can adapt to complex and changing marine environments and geological conditions, and the pull-out resistance of their anchoring structures is the key to fully exerting the effectiveness of floating structures, and has received great attention from researchers in the marine engineering community. Among them, the torpedo anchor foundation is the latest new type of foundation developed, which has the characteristics of simple and efficient installation and economical cost. In particular, it overcomes the shortcomings of traditional anchor foundations that are heavily dependent on operating water depth and installation equipment, and is considered to be the new type of foundation with the most development potential.

[0003] The installation of a torpedo anchor is relatively quick and easy. It only requires lifting the anchor in the water to a certain distance from the mud surface, releasing the anchor body, and penetrating the soil under its own weight to reach the specified depth. However, in hard sandy soil, it is difficult for the anchor body to reach the specified soil layer by its own weight alone, and the bearing capacity cannot meet the design requirements. Summary of the invention

[0004] The purpose of the present invention is to provide a torpedo anchor with a deeper anchoring length in order to overcome the defects of the above-mentioned prior art that the anchor body is difficult to reach the specified soil layer by its own weight in the hard sandy layer and the bearing capacity cannot meet the design requirements.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A torpedo anchor capable of deepening the anchoring length comprises an anchor body and an anchor head which are engaged with each other, wherein a screw is arranged in the anchor body, one end of the screw is connected to the anchor head via a nut, and the other end is fixed with a motor with a power storage function, the motor is connected to the anchor body via a connecting rod, and a rotating blade is arranged on the rod body of the screw near one end of the nut.

[0007] The number of the rotating blades is 4.

[0008] The rotating blade comprises a blade and a spring, and the blade is composed of a plurality of blade sections.

[0009] Preferably, the number of the blade sections is 4, including a first blade section, a second blade section, a third blade section and a fourth blade section, and the lengths of the first blade section, the second blade section, the third blade section and the fourth blade section decrease in sequence.

[0010] The first blade section, the second blade section and the third blade section are provided with slot blocks and grooves engaged with the slot blocks.

[0011] Preferably, the groove and the groove block are respectively arranged at two ends of the first blade section, the second blade section and the third blade section, and the groove block is connected to the first blade section, the second blade section and the third blade section through a spring sheet.

[0012] The spring is arranged inside the blade section and passes through the four blade sections.

[0013] A mooring hole is arranged on one end of the anchor body away from the anchor head, and a mooring steel cable is arranged in the mooring hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention adds a rotating blade at the anchor head. When encountering a hard soil layer, the motor is started to drive the rotating blade to cut the hard soil layer, so that the torpedo anchor reaches a specified depth and meets the pull-out resistance requirements.

[0016] 2. The present invention is provided with a slot block and a groove engaged with the slot block, which fixes the blade section when the blade section is extended, thereby preventing the blade section from being separated when cutting the soil layer, and improving the stability of the rotating blade.

[0017] 3. The blade sections of the present invention are connected by springs, so that they can be compressed in the anchor body when not in use and can be ejected in time when the soil layer needs to be cut. The blade sections have high flexibility and can adapt to various terrains. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0027] like Figure 1 As shown, a torpedo anchor capable of deepening the anchoring length comprises an anchor body 2 and an anchor head 8 which are engaged with each other, a screw rod 5 is arranged in the anchor body 8, one end of the screw rod 5 is connected to the anchor head 8 via a nut 7, and a motor 3 with a power storage function is fixed to the other end, the motor 3 is connected to the anchor body 2 via a connecting rod 4, and a rotating blade 6 is arranged on the rod body of the screw rod 5 near the nut 7.

[0028] like Figure 4 As shown, the number of the rotating blades 6 is four.

[0029] The rotating blade 6 comprises a blade and a spring 9, and the blade is composed of a plurality of blade sections.

[0030] like Figure 6 As shown, the number of blade sections is 4, including a first blade section 13, a second blade section 14, a third blade section 15 and a fourth blade section 16, and the lengths of the first blade section 13, the second blade section 14, the third blade section 15 and the fourth blade section 16 decrease in sequence.

[0031] The first blade segment 13 , the second blade segment 14 and the third blade segment 15 are provided with slot blocks 11 and grooves 12 engaged with the slot blocks.

[0032] like Figure 5 As shown, the groove 12 and the groove block 11 are respectively arranged at the two ends of the first blade segment 13, the second blade segment 14 and the third blade segment 15, and the groove block 11 is connected to the first blade segment 13, the second blade segment 14 and the third blade segment 15 through a spring sheet.

[0033] The spring 9 is arranged inside the blade section and passes through the four blade sections.

[0034] like Figure 3 As shown, a mooring hole 10 is provided at one end of the anchor body 2 away from the anchor head 8, and a mooring steel cable 1 is provided in the mooring hole.

[0035] Embodiment 1

[0036] like Figure 2As shown, when the anchor head 8 encounters a hard soil layer and reaches a specified depth, the motor 3 rotates to drive the anchor head 8 to separate from the anchor body 2, and the rotating blade 6 freely contacts the anchor body 2 and the anchor head 8. When the anchor head 8 and the anchor body 2 reach a certain distance, due to the loss of support, the spring 9 pre-loaded inside ejects the blade section, and the slot block 11 is stuck in the corresponding groove 12, completing the extension of the rotating blade 6. Driven by the motor 3, the rotating blade 6 begins to rotate and cut the soil layer, so that the torpedo anchor is continuously lowered and finally reaches the specified depth.
