When the torpedo anchor strikes the seabed, the anchor body penetrates the ecological outer shell and enters the soil. The ecological outer shell and the internal elastic support mechanism remain on the soil surface, forming an artificial reef. The anchor body includes an anchor body, a rotating mechanism located within the anchor body, and an anchor solid embedded in a groove around the anchor body. The anchor solid is pivotally connected to the rotating mechanism. After the anchor body penetrates the soil, the rotating mechanism rotates, causing the anchor solid to rotate out of the anchor body and insert into the soil. An ejector plate containing a mixed bacterial solution is installed inside the anchor solid. When the anchor solid rotates out of the anchor body groove, the ejector plate is ejected from the anchor solid and inserts into the soil. In this invention, after the torpedo anchor penetrates, the ecological outer shell remains on the soil surface as an artificial reef. The mixed bacterial solution's MIP (microbial polymerase) effect consolidates the soil around the torpedo anchor. The internal design of the anchor body with an unfolding mechanism enhances the load-bearing capacity after penetration, achieving both ecological and engineering benefits.

Description

Technical Field

[0001] This invention relates to a torpedo anchor, and more particularly to an eco-friendly torpedo anchor and its method of use. Background Technology

[0002] In recent years, the development of offshore oil and gas resources has gradually shifted from shallow to deep waters. Fixed platforms, due to their increasing cost with depth, are generally only suitable for shallow waters, while floating platforms, which are more versatile, are mostly used in deep-sea areas. Floating platforms rely on their own buoyancy to support their superstructure weight and are anchored in place by a mooring system. The mooring system, as a component of deep-sea floating structures, plays a crucial role in their operational safety. Torpedo anchors, a type of dynamically installed anchor that has emerged in recent years, have advantages over other anchor types, including no need for various auxiliary devices, simple and short installation cycle, low economic cost, and minimal impact of installation costs on water depth. They are widely considered one of the most promising deep-sea anchoring foundations.

[0003] The installation of torpedo anchors primarily relies on descent, which consists of two parts: descent in seawater and penetration into the seabed soil. Previous studies have focused on conical anchor tips to ensure sufficient penetration depth. However, while this conical tip maximizes the anchor's penetration capability, the resistance encountered during descent is greater than that of an optimal streamlined design, resulting in significant kinetic energy loss and reduced penetration ability. Furthermore, torpedo anchors have always suffered from insufficient load-bearing capacity. Existing research often attempts to enhance load-bearing capacity by altering the physical structure, such as increasing the contact area between the anchor and the soil, through methods like partially extended and expanded tail fins. However, with time and changes in the complex marine environment, the cyclical loads caused by waves weaken the surrounding soil, gradually reducing the anchor's load-bearing and pull-out resistance. Summary of the Invention

[0004] Purpose of the invention: The present invention aims to provide an ecological torpedo anchor and its method of use that reduces kinetic energy loss and improves the penetration capability and pull-out bearing capacity of the torpedo anchor.

[0005] Technical Solution: The present invention discloses an ecological torpedo anchor, comprising a streamlined ecological outer shell and an anchor body and an elastic support mechanism disposed within the ecological outer shell. The anchor body is located below the elastic support mechanism. When the torpedo anchor strikes the seabed soil, the anchor body penetrates the head of the ecological outer shell and enters the soil. The ecological outer shell and the internal elastic support mechanism remain on the soil surface, forming an artificial reef. The anchor body includes an anchor body, a rotating mechanism disposed within the anchor body, and an anchor solid embedded in a groove around the anchor body. The anchor solid is pivotally connected to the rotating mechanism. After the anchor body penetrates the soil, the rotating mechanism rotates, causing the anchor solid to rotate out of the anchor body and insert into the soil. The anchor solid is provided with a pop-out plate containing a mixed bacterial solution. When the anchor solid rotates out of the anchor body groove, the pop-out plate pops out from the anchor solid and inserts into the soil.

[0006] Preferably, the pop-out rigid plate is elastically pivotally connected to the anchor body, and when the anchor body is located in the anchor body groove, the pop-out rigid plate is constrained by the anchor body groove and is in an elastically compressed state.

[0007] Preferably, the upper surface of the ejector plate is provided with a liquid storage tank, and a semi-cylindrical injection pipe is provided at the bottom of the ejector plate. One end of the injection pipe is pivotally connected to the bottom of the ejector plate, and the other end is a free end embedded in the anchor body. When the ejector plate is ejected from the anchor body, the free end of the injection pipe falls and inserts into the soil under the action of soil resistance. The injection pipe contains a mixed bacterial solution for solidifying the soil.

[0008] Preferably, the inner surface of the ecological shell and the elastic support mechanism are coated with nutrient salt paint, and the ecological shell is provided with an injection pipe containing a mixed bacterial solution for soil solidification.

[0009] Preferably, the elastic support mechanism includes a folding frame and a spring pressure plate. The folding frame includes upper and lower fixed plates and a folding skeleton disposed between the upper and lower fixed plates. The spring pressure plate includes several spring groups and a connecting plate. The upper end of the spring group is connected to the lower fixed plate of the folding frame, and the lower end is connected to the connecting plate.

[0010] Preferably, the elastic support mechanism is movably connected to the anchor body via an anchor chain; both the folding frame and the spring pressure plate are provided with through holes to facilitate the passage of the anchor chain, and a pressure valve for limiting the sliding of the anchor chain is provided between the spring pressure plate and the anchor chain; the pressure valve includes several groups of limiting blocks and springs, one end of the spring is connected to the connecting plate, and the other end is connected to the limiting block, and a group of opposite limiting blocks abut against the anchor chain. When the pressure is greater than a specified value, the pressure valve opens to allow the anchor chain to slide in the through hole.

[0011] Preferably, the rotating mechanism includes a rotating shaft and a power mechanism. A gear is provided on the rotating shaft at a position opposite to the groove of the anchor body. The anchor body is sleeved on the rotating shaft and meshes with the gear of the rotating shaft. When the rotating shaft rotates, it drives the anchor body to rotate and extend out of the groove of the anchor body.

[0012] Preferably, the anchor body is a fan-shaped or arc-shaped steel sheet with sharp outer edges.

[0013] Preferably, the head of the ecological shell is a calcium carbonate layer and is provided with a weakening groove; the outer layer of the main body of the ecological shell is a calcium carbonate sleeve, the inner layer is a metal cylinder, the tail of the ecological shell is provided with an openable baffle, and the ecological shell is provided with holes all around.

[0014] The method of using an ecological torpedo anchor according to the present invention includes the following steps:

[0015] (a) Pre-preparation of mixed bacterial solution;

[0016] (b) After injecting the ejector plate into the mixed bacterial solution, place it into the anchor body, and then place the anchor body into the groove of the anchor body in sequence. Apply pressure to make the ejector plate constrained by the inner wall of the groove of the anchor body.

[0017] (c) Open the tail of the anchor body, pivot the rotating mechanism to the anchor body, close the tail of the anchor body and connect the anchor chain;

[0018] (d) Open the baffle at the tail of the ecological shell, insert the anchor body and the elastic support mechanism into the ecological shell in sequence, and finally close the tail of the ecological shell.

[0019] (e) The assembled ecological torpedo anchor is dropped into the water. After it penetrates the soil, the rotating mechanism is started to drive the anchor body to rotate out of the anchor body and insert into the soil. During the outward rotation of the anchor body, the ejected steel plate ejects the anchor body outward and inserts into the soil, and the mixed bacterial solution is injected into the soil.

[0020] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: 1. It draws on the design concept of armor-piercing discarding sabot projectiles, leaving an ecological outer shell on the soil surface as an artificial reef after the torpedo anchor penetrates. Utilizing the MIP (microbial polymerase) effect of the pre-formed microbial community, it improves the marine environment while further consolidating the anchor body with the surrounding environment, enhancing its load-bearing capacity. Simultaneously, the torpedo anchor is designed with an internal deployment mechanism, directly increasing the horizontal cross-sectional area of ​​the torpedo anchor by inserting the anchor body and ejecting the rigid plate, thereby improving the torpedo anchor's pull-out bearing capacity. Furthermore, after the ejected rigid plate is inserted into the soil, it releases the pre-formed microbial solution to consolidate the soil surrounding the anchor body, further enhancing its load-bearing capacity. 1. Enhanced bearing capacity; 2. A streamlined ecological shell is fitted over the main body of the anchor, giving it the optimal motion form in fluids, which can greatly reduce the resistance loss of the torpedo anchor falling in water, increase the penetration depth of the torpedo anchor, and improve the pull-out bearing capacity of the torpedo anchor; 3. The MIP method is used to consolidate the upper part of the anchor body and the surrounding soil, which increases the friction between the anchor body and the surrounding soil and the weight of the upper soil, and increases the shear area and shear strength of the soil in the upper part of the anchor body, which greatly enhances the pull-out bearing capacity of the torpedo anchor; 4. The materials and technologies used are almost all environmentally friendly, taking into account both engineering and ecological attributes. Attached Figure Description

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0035] In recent years, scientific research has shown that the marine ecological environment is deteriorating, and the degradation of coral reefs is threatening the habitats of many marine organisms. Scientists have developed various forms of artificial reefs and discovered that some long-operating offshore platforms have formed ecosystems composed of marine attached organisms on their bottoms. Due to the large size of torpedo anchors, a type of offshore platform mooring system, they can also serve as a good carrier for artificial reefs. Based on this, the design aims to leave an outer shell on the soil surface after the torpedo anchor penetrates, serving as an artificial reef. Simultaneously, the pre-formed microbial community's MIP (microbial polymerase chain reaction) effect can be used to consolidate the soil around the torpedo anchor, enhancing its bearing capacity and achieving the ecological benefits of the torpedo anchor. This outer shell design can draw inspiration from the design of armor-piercing discarding sabot (APDS) projectiles. APDS projectiles are improved versions of traditional armor-piercing projectiles designed to enhance their destructive power. They consist of a tungsten alloy core smaller than the main gun caliber, encased in a lightweight metal ring of the same caliber as the main gun. Upon firing, the lightweight metal ring detaches, while the tungsten alloy core continues its trajectory towards the target. This is to balance the aerodynamic requirements of firing high-speed projectiles from large-caliber tank guns with the requirement of a projectile tip that penetrates armor. Meanwhile, the shape that minimizes drag when an object moves forward in the ocean is streamlined. Therefore, the outer shell can be designed to be streamlined to reduce drag when the torpedo anchor moves forward.

[0036] like Figure 1-2 As shown, the ecological torpedo anchor of this invention includes an ecological outer shell 1, an anchor body 2, and an elastic support mechanism 3. Both the elastic support mechanism 3 and the anchor body 2 are housed within the ecological outer shell 1, with the anchor body located below the elastic support mechanism. The elastic support mechanism 3 is movably connected to the anchor body 2 via an anchor chain 4. When the torpedo anchor strikes the seabed, the anchor body pierces the head of the ecological outer shell and penetrates into the soil. The ecological outer shell and the internal elastic support mechanism remain on the soil surface, forming an artificial reef.

[0037] The ecological outer shell 1 is streamlined, providing excellent drag reduction. It features a calcium carbonate anchor wing 5 on the outer side to maintain stability during the torpedo anchor's descent. The head of the ecological outer shell 1 is a calcium carbonate layer with a weakening groove, facilitating penetration of the ecological outer shell 1 by the anchor body 2. The outer layer of the ecological outer shell 1 is a calcium carbonate sleeve, and the inner layer is a steel cylinder. The inner side of the steel cylinder has a groove for accommodating the injection pipe 6, which contains a pre-prepared mixed bacterial solution. This mixed bacterial solution is cultured and prepared using the MIPC method and includes components such as Bacillus pasteurellii and urea; the specific component content can be adjusted according to the seawater environment of the application site. The tail of the ecological outer shell 1 has an openable baffle, and the entire ecological outer shell has holes to facilitate the movement of marine organisms. The injection pipe 6 has lateral seepage holes that seal with the groove in the inner layer of the ecological outer shell. Figure 12 As shown.

[0038] The elastic support mechanism 3 includes a folding frame 31 and a spring pressure plate 32. The folding frame 31 includes upper and lower fixed plates and a folding skeleton disposed between the upper and lower fixed plates. Figure 3-6 As shown. The spring pressure plate 32 includes several spring assemblies and a connecting plate. The lower end of each spring assembly is connected to the connecting plate, and the upper end is connected to the lower fixing plate of the folding frame, as shown. Figure 10 As shown. Both the folding frame 31 and the spring pressure plate 32 have through holes to facilitate the passage of the anchor chain 4. A pressure valve 33 is provided between the spring pressure plate 32 and the anchor chain 4 to restrict the sliding of the anchor chain 4. The pressure valve prevents excessive pressure from damaging the components. The pressure valve 33 includes several groups of limiting blocks and springs. One end of the spring is connected to the connecting plate, and the other end is connected to the limiting block. A group of opposing limiting blocks abuts against the anchor chain 4. When the anchor chain is under tension, the pressure valve opens when the pressure exceeds a certain level, allowing the anchor chain 4 to slide within the through hole. Figure 11 As shown.

[0039] The inner surfaces of the ecological shell 1, the folding frame 31, and the spring pressure plate 32 are all coated with nutrient salt paint.

[0040] When the torpedo anchor strikes the seabed soil, the anchor body 2 pierces the ecological shell 1 and continues to penetrate the soil. The ecological shell 1 and the elastic support mechanism 3 remain on the soil surface. The anchor body 2 pulls the spring pressure plate 32 through the anchor chain 4, causing the spring assembly inside to stretch and store elastic potential energy. When the connecting plate withstands resistance to a certain extent, the pressure valve 33 inside the through hole opens, allowing the anchor chain to pass freely. After the anchor body has penetrated, the pressure valve closes again, fixing the relative position of the anchor chain and the anchor body. At the same time, the folding frame 31 gradually unfolds under the pull of the spring pressure plate 32. The fixing plate of the folding frame 31 presses the injection pipe 6 into the soil, injecting mixed bacterial solution into the soil above the anchor body. The mixed bacterial solution in the soil decomposes urea through the mineralization of Bacillus pasteurellii to generate carbonate ions, which combine with calcium ions in the sea to form calcium carbonate and consolidate the surrounding soil. Because the outer layer of the ecological shell is made of environmentally friendly calcium carbonate, and the internal nutrient coating attracts marine life to attach, the perforations around the shell and the complex structure of the internal folding frame further attract a large number of marine organisms to attach and inhabit it. Diatoms and other reef-building animals will attach and inhabit the shell, creating a sturdy bio-reef on its surface and inside, increasing its weight and solidifying it with the surrounding environment. Figure 5-6 As shown.

[0041] like Figure 13As shown, the anchor body 2 includes an anchor body 21, a rotating mechanism 22 disposed within the anchor body 21, and an anchor body 23 embedded in the grooves around the anchor body 21. The anchor body 23 is a fan-shaped or arc-shaped steel sheet with a sharp outer side. The rotating mechanism 22 includes a rotating shaft 221 and a power mechanism 222. The rotating shaft 221 is perpendicular to the grooves of the anchor body, and a gear is provided at a position opposite to the grooves. The anchor body 23 is horizontally arranged, with one end disposed in the groove of the anchor body and the other end disposed on the rotating shaft and meshing with the gear on the rotating shaft. The grooves around the anchor body 21 are staggered, with each groove closed on the left and open on the right, with one side closed to prevent excessive rotation of the anchor body. One or more sets of rotating shafts 221 can be provided, and one or more sets of power mechanisms 222, i.e., motors, can be provided. The cable for operating the motor is disposed on the anchor chain 4, and the cable is wrapped with a rubber protective layer.

[0042] After the torpedo anchor penetrates the soil, the motor starts, driving the rotating shaft 221 to rotate, which in turn drives the anchor body 23 to rotate. When it rotates to a certain angle, part of the anchor body extends out of the anchor body and inserts into the soil, such as... Figure 7 As shown. The anchor bodies 23 are arranged alternately on the anchor body, which can increase the cross-sectional area of ​​the torpedo anchor by 2 to 3 times and strengthen the vertical pull-out bearing capacity and horizontal tensile moment of the torpedo anchor.

[0043] like Figure 9-10 As shown, the anchor body 23 has a pop-out rigid plate 24 inside. One corner of the pop-out rigid plate 24 is pivotally connected to the inside of the anchor body 23, and the other side is connected to the inside of the anchor body through a spring. When the anchor body is located in the anchor body groove, the pop-out rigid plate is constrained by the anchor body groove and the spring is in a compressed state. When the anchor body is screwed out of the anchor body groove, the pop-out rigid plate inside pops out of the anchor body and inserts into the soil, increasing the horizontal area a second time and further enhancing the bearing capacity. The upper surface of the pop-out rigid plate 24 is provided with a liquid storage tank 241, and a semi-cylindrical injection pipe 6 is pivotally installed at the bottom. The semi-cylindrical injection pipe has a seepage hole on its flat side, and the flat side abuts against the pop-out rigid plate. When the pop-out rigid plate is built into the anchor body, the semi-cylindrical injection pipe is sealed. When the pop-out rigid plate pops out of the anchor body, one end of the semi-cylindrical injection pipe detaches from the pop-out rigid plate and opens obliquely into the soil under the action of resistance. The storage tank and injection pipe are equipped with pre-made mixed bacterial solution. After the ejector plate and injection pipe are inserted into the soil, the mixed bacterial solution slowly seeps into the surrounding soil and consolidates the surrounding soil through the action of MICP, further enhancing the bearing capacity.

[0044] The method of using an ecological torpedo anchor according to the present invention includes the following steps:

[0045] (a) Pre-preparation of mixed bacterial solution;

[0046] (b) After injecting the ejector plate into the mixed bacterial solution, place it into the anchor body, and then place the anchor body into the groove of the anchor body in sequence. Apply pressure to make the ejector plate constrained by the inner wall of the groove of the anchor body.

[0047] (c) Open the tail of the anchor body, engage the rotating shaft with the anchor body, connect the rotating shaft to the power unit, close the tail of the anchor body and connect the anchor chain;

[0048] (d) Open the baffle at the tail of the ecological shell, insert the injection tube into the tube groove inside the ecological shell, keep the seepage hole of the injection tube sealed with the tube groove wall, and inject the mixed bacterial solution; then place the anchor body, spring pressure plate and folding frame into the ecological shell in sequence, and finally close the tail of the ecological shell.

[0049] (e) The assembled ecological torpedo anchor is put into the water. After it penetrates the soil, the power mechanism is started to drive the rotating shaft to rotate, which in turn drives the anchor body to rotate out of the anchor body and insert into the soil. During the outward rotation of the anchor body, the ejector plate is no longer constrained by the groove of the anchor body and ejects the anchor body outward under the action of the spring and inserts into the soil, further increasing the horizontal anchoring area of ​​the torpedo anchor. At the same time, one end of the injection pipe is separated from the bottom of the ejector plate and inserted into the soil at an angle to inject mixed bacterial solution into the soil.

[0050] The working principle of this invention is as follows: The streamlined shape of the ecological shell provides excellent drag reduction, and the anchor fins installed on its surface maintain stability during descent. The head of the ecological shell is made of fragile calcium carbonate material. Because the weight and hardness of the anchor body are much greater than those of the ecological shell, the internal anchor body easily penetrates the head of the ecological shell and penetrates into the soil with minimal loss of kinetic energy when the torpedo anchor strikes the seabed through the liquid. After the anchor body penetrates the soil, the ecological shell remaining on the surface acts as an artificial reef, gradually attracting marine organisms to attach and further building the reef, increasing the weight of the ecological shell while consolidating it with the surrounding environment. After the torpedo anchor penetrates the soil, the motor inside the anchor body starts, rotating the shaft and causing the anchor body to rotate clockwise out of the anchor body groove and insert into the soil, enhancing the bearing capacity. At the same time, the built-in ejector steel plate is ejected under the action of a spring, further increasing the horizontal area and strengthening the vertical pull-out bearing capacity and horizontal tensile moment of the torpedo anchor. The pop-out rigid plate built into the anchor body releases mixed bacterial solution during the insertion into the soil, which consolidates the surrounding soil through the action of MICP, further enhancing the bearing capacity.
