Description

Technical Field

[0001] The present invention relates to the technical field of torpedo anchors, in particular to a recyclable umbrella-type torpedo anchor. Background Art

[0002] Existing torpedo anchor technologies include:

[0003] CN114954786A discloses a torpedo anchor with a retractable anchor plate and its installation method. The invention comprises an anchor cable, an anchor body, an anchor tip, multiple anchor wings, multiple sets of retractable anchor plate structures, and several sets of electromagnetic correction devices. The electromagnetic correction devices maintain the torpedo anchor in a vertical position during descent, increasing its penetration depth and improving positioning accuracy. The retractable anchor plate structure increases the contact area between the torpedo anchor body and the seabed soil and the normal load-bearing area, thereby increasing its ultimate bearing capacity and stability.

[0004] CN115367050A discloses a submarine torpedo anchor and its grouting reinforcement method. This invention includes an anchor rod, anchor eye, anchor tip, anchor wings, and a deep-sea high-strength valve. This invention utilizes multi-step grouting to diffuse the slurry around the anchor body, forming a grouting mass, thereby preventing the uncertainty caused by seabed soil and seawater on subsequent grouting diffusion.

[0005] CN218703742U Torpedo Anchor. This invention includes an anchor body, a connecting structure, a counterweight, and a cable. This anchor allows the counterweight to be recovered and reused after the anchor body is inserted into the seabed, thus avoiding resource waste.

[0006] CN116080823A discloses a torpedo anchor containing an expansion airbag. The invention comprises an anchor body, anchor wings, and an anchor head. An expansion control airbag is positioned between the anchor body and the anchor head. When the electric heating control device is activated, the air in the anchor chamber is slowly heated to the decomposition temperature of sodium azide. At this point, the sodium azide rapidly decomposes and releases a large amount of nitrogen, which expands the folded airbag, increasing the horizontal cross-sectional area of ​​the torpedo anchor and improving its pullout bearing capacity.

[0007] CN212267764U describes a new torpedo anchor based on a flat anchor load-bearing system. The invention comprises an anchor body, a tail fin, a wedge-shaped anchor head for deflection, and a mooring ring. During actual use, the anchor body, under the action of the anchor chain, gradually becomes perpendicular to the direction of force applied, expanding the torpedo anchor's load-bearing area and significantly improving its ultimate pullout capacity.

[0008] CN218431623U discloses a torpedo anchor with a freely retractable fluke. The invention comprises an anchor body, a transmission device located inside the anchor body, and a movable fluke. By pulling a traction bar and rotating a gear, the fluke is extended or retracted, achieving the effects of increased load-bearing capacity and recyclability.

[0009] CN212267765U A torpedo anchor provided with an additional anchor body and the additional anchor body can be unfolded outward. The invention mainly consists of an anchor body, anchor wings, an additional anchor body, a fixed hinge and an anchor head. However, when the torpedo anchor is subjected to tension, the torque generated by the force acting on the additional anchor body on the fixed hinge of the anchor head causes the additional anchor body to unfold outward under the action of the torque, thereby expanding the stress area.

[0010] CN115303417A A recoverable side wing spread torpedo anchor suitable for deep sea anchoring. The invention includes a penetration anchor head, the anchor body is welded at the top of the penetration anchor head, and the anchor body is rotatably connected with the wing plate at the bottom of both sides, and a short chain is fixedly arranged on the opposite side of the two groups of wing plates. The invention releases the constraint of the long chain by pulling the recovery steel cable upward, turns over the wing plate parallel to the anchor body, and makes the wing plate resistance return to the minimum state, so that the side wing spread torpedo anchor can be recovered by pulling the main steel cable upward, and the side wing spread torpedo anchor can be recovered.

[0011] CN107933828A A new type of torpedo anchor with an expandable anchor head and its installation method. The invention includes an anchor head composed of four conical plates, a guide rod, an anchor body, an anchor tail cover plate, a cable ring, etc. The invention expands the conical plates of the torpedo anchor head, increases the stress area of the anchor body, and further improves the carrying capacity of the anchor body.

[0012] CN108860473B A torpedo anchor with partially deployable tail wings. The invention mainly includes rotating tail wings and fixed tail wings. After penetrating the seabed, a certain distance is pulled up by the anchor chain to make the rotating tail wings rotate to fully deploy, and the rotating tail wings can hold a large amount of seabed soil after deployment.

[0013] There are still some problems in the existing related torpedo anchors. The specific problems are described as follows:

[0014] (1) Although some torpedo anchors enhance the carrying capacity through deformation means, they do not consider how to recover;

[0015] (2) Some torpedo anchors consider recovery, but only part of the structure can be recovered, and cannot be completely reused;

[0016] (3) Some torpedo anchors consider both increasing the carrying capacity and recovery, but the key parts involved in recovery are prone to deformation when bearing load, and the vertical load resistance is weak, thereby affecting the recovery. SUMMARY

[0017] The present application provides a recoverable umbrella-type torpedo anchor, which aims to solve the technical problems existing in the prior art.

[0018] The present invention provides a recyclable umbrella-type torpedo anchor, comprising a mooring line, an auxiliary cable, a torpedo anchor shell, a wing plate, a restraining ring, a core tube, a tow bar, and a position-limiting clasp.

[0040] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with reference to the drawings and examples.

[0041] As shown in Figures 1 to 5 the present application, a recyclable umbrella-shaped torpedo anchor comprises a mooring line 7, an auxiliary cable 8, a torpedo anchor shell 1, a wing plate 2, a constraint ring 6, a core barrel 5, a traction strip 3, and a limiting snap ring 4. The top of the torpedo anchor shell 1 is connected with the mooring line 7, and the bottom of the torpedo anchor shell 1 is provided with a cone head 11. The core barrel 5 is composed of a plurality of barrel petals 51, and the bottom of each barrel petal 51 is hinged to the cone head 11. The wing plate 2 is hinged to the torpedo anchor shell 1. The limiting snap ring 4 is connected with the wing plate 2 through the traction strip 3. The auxiliary cable 8 is connected with the constraint ring 6.

[0042] When the torpedo anchor is launched, the constraint ring 6 is sleeved on the top of the core barrel 5, the limiting snap ring 4 is clamped in the core barrel 5, and the wing plate 2 keeps closed and close to the torpedo anchor shell 1 by relying on the water flow when descending.

[0043] When the torpedo anchor works, the wing plate 2 is opened in the shape of an umbrella by tensioning the mooring line 7.

[0044] When the torpedo anchor is recycled, the constraint ring 6 is separated from the top of the core barrel 5 by the auxiliary cable 8, the barrel petals 51 are unfolded, and the limiting snap ring 4 is separated from the core barrel 5, so as to destroy the umbrella-shaped structure of the wing plate 2.

[0045] During the installation and launching stage of the torpedo anchor, the torpedo anchor is launched at a predetermined position and penetrates into the seabed by relying on its own weight. During the working stage, the mooring line 7 is tensioned to open the umbrella-shaped structure and enhance the bearing capacity. During the recycling stage, the auxiliary cable 8 is tensioned to destroy the umbrella-shaped structure and reduce the bearing capacity, and then the mooring line 7 is tensioned for recycling.

[0046] After recycling, the wing plate 2, the traction strip 3 and the limiting snap ring 4 are not left in the seabed. When entering the recycling state, the bottom of the wing plate 2 is still connected to the torpedo anchor shell 1, the traction strip 3 is connected to the wing plate 2, and the limiting snap ring 4 is connected to the traction strip 3. At this time, the wing plate 2 cannot provide resistance as in the working state, and the mooring line 7 is pulled during recycling to pull out all the torpedo anchor structures from the seabed.

[0047] The wing plate 2 is hinged to the outside of the torpedo anchor shell 1, the core barrel 5 is located inside the torpedo anchor shell 1, and the torpedo anchor shell 1 is provided with a shell hole 12 for the traction strip 3 and the limiting snap ring 4 to enter and exit.

[0048] When the torpedo anchor is launched, the traction strip 3 is folded inside the torpedo anchor shell 1, one end of the traction strip 3 passes through the shell hole 12 and is connected with the wing plate 2. When the torpedo anchor works, the traction strip 3 is taut and one end of the traction strip 3 passes through the shell hole 12 and is connected with the wing plate 2. When the torpedo anchor is recycled, the traction strip 3 and the limiting snap ring 4 pass out of the shell hole 12.

[0049] The traction bar 3 can adopt a chain structure such as an iron chain or a steel cable. The length of each traction bar 3 can be selected according to the angle at which the wing plate 2 is unfolded, so as to ensure that when the traction bar 3 is tightened, the wing plate 2 flips to the required angle to present an umbrella-shaped structure. When deployed, the wing plate 2 is close to the torpedo anchor shell 1. At this time, the traction bar 3 is not subjected to force, and the traction bar 3 is retracted and wound in the torpedo anchor shell 1 for standby use. When recovered, the core tube 5 releases the restriction on the limit snap ring 4, and the wing plate 2 drags the limit snap ring 4 out of the shell hole 12 through the traction bar 3. At this time, the wing plate 2 has no restraining force, and the entire umbrella-shaped configuration is destroyed, reducing the bearing capacity.

[0050] like Figure 6 As shown, the limiting snap ring 4 includes a limiting head 41, a connecting rod 42, and a traction ring 43. The two ends of the connecting rod 42 are connected to the limiting head 41 and the traction ring 43, respectively. The traction ring 43 is connected to the traction bar 3. The connecting rod 42 passes through the core tube 5, and the limiting head 41 is clamped inside the core tube 5. The limiting head 41 can adopt a spherical head, a square head, or other structures, and the traction ring 43 can adopt a circular ring, a square ring, or other structures. The traction ring 43 is used to fix one end of the traction bar 3. The limiting head 41 is used to confine the entire limiting snap ring 4 within the core tube 5 when the core tube 5 is constrained, so that the traction ring 43 can pull the traction bar 3 to maintain the umbrella shape of the wing panel 2.

[0051] like Figure 7 As shown, the cylinder petals 51 are plate-like structures. Multiple cylinder petals 51 form a hollow core tube 5. The side of the cylinder petals 51 is provided with a limiting concave edge 52. When the core tube 5 is constrained, the limiting concave edges 52 of two adjacent cylinder petals 51 are connected to form a limiting hole 53. The connecting rod 42 passes through the limiting hole 53. The aperture of the limiting hole 53 is larger than the rod diameter of the connecting rod 42 and smaller than the width of the limiting head 41. The plate-like cylinder petal 51 structure is one embodiment of the cylinder petal 51. The plate shape can be an arc plate, a flat plate, an angled plate, etc. Different plate-like cylinder petals 51 form different hollow core tube 5 structures when constrained by the constraint ring 6. That is, the core tube 5 can be cylindrical or square. Each concave limiting edge 52 forms half of a limiting hole 53. When two concave limiting edges 52 meet, the limiting hole 53 formed can restrain the limiting snap ring 4. Specifically, the connecting rod 42 of the limiting snap ring 4 is inserted into the limiting hole 53, the limiting head 41 is exposed in the hollow area in the center of the core tube 5, and the pulling ring 43 is exposed on the periphery of the core tube 5. When the core tube 5 is released, the multiple petals 51 will disperse under the pulling force of the limiting snap ring 4, and the limiting hole 53 will be destroyed, thereby allowing the limiting snap ring 4 to separate from the core tube 5.

[0052] like Figure 8As shown, the cylinder petals 51 are block-shaped structures, and a plurality of cylinder petals 51 form a solid core tube 5. The side surfaces of the cylinder petals 51 are provided with limiting grooves 54 adapted to the limiting heads 41 and the connecting rods 42. When the core tube 5 is constrained, the limiting grooves 54 of two adjacent cylinder petals 51 are docked to form a limiting chamber, and the limiting heads 41 and the connecting rods 42 are stuck in the limiting chamber. The block-shaped cylinder petal 51 structure is another embodiment of the cylinder petals 51. There is no limit on the thickness of the cylinder petals 51. In order to obtain greater strength, the cylinder petals 51 can be made into a solid structure. The block-shaped structure can be a block-shaped structure with arc edges, a block-shaped structure with flat edges, a block-shaped structure with angled edges, and the like. Different block-shaped cylinder petals 51 form different solid core tube 5 structures when constrained by the constraint ring 6, that is, the core tube 5 can be cylindrical or square. Each limiting groove 54 forms a half-surface limiting chamber. When two limiting grooves 54 meet, the limiting chamber formed can restrain the limiting snap ring 4. Specifically, the limiting head 41 and connecting rod 42 of the limiting snap ring 4 are partially engaged within the limiting chamber, while the traction ring 43 is exposed on the periphery of the core tube 5. When the core tube 5 is released, the multiple petals 51 will disperse under the pulling force of the limiting snap ring 4, destroying the structure of the limiting chamber and allowing the limiting snap ring 4 to separate from the core tube 5.

[0053] There is no limit to the number of tube petals 51 that make up the core tube 5. One or more limiting snap rings 4 can be connected between two tube petals 51. There is no limit to the number of wing plates 2 hinged to the torpedo anchor shell 1. One limiting snap ring 4 can be connected to one wing plate 2, or multiple wing plates 2 can be connected to the same limiting snap ring 4. One wing plate 2 can also be connected to multiple limiting snap rings 4 at the same time. Various combinations can be matched according to actual needs.

[0054] like Figure 4 and Figure 5 As shown, the bottom of the cylindrical petals 51 is provided with an avoidance chamfer 55 to provide expansion space for the bottom of the cylindrical petals 51. The avoidance chamfer 55 ensures that when each cylindrical petal 51 is spread out, there is enough space at the bottom for it to turn over. If the avoidance chamfer 55 is not provided, the cylindrical petals 51 may collide with each other during the expansion process, resulting in failure to spread smoothly and continued jamming of the limit clamp 4.

[0055] A first protruding foot 56 is provided at the bottom of the cylindrical petal 51, and a second protruding foot 13 is provided on the cone head 11. The first protruding foot 56 and the second protruding foot 13 are hingedly connected via a rotating shaft 14. Through the structural coordination of the first protruding foot 56, the second protruding foot 13, and the rotating shaft 14, the bottom of the cylindrical petal 51 can be flipped relative to the cone head 11, thereby allowing the cylindrical petals 51 to spread apart to release the limiting snap ring 4. The hinge height of the first protruding foot 56 at the bottom of the cylindrical petal 51 can be adjusted according to actual needs, and the position of the second protruding foot 13 on the cone head 11 can also be adjusted accordingly to meet the spreading angle of the cylindrical petals 51 when the space inside the torpedo anchor housing 1 is of different sizes, thereby ensuring that the limiting snap ring 4 can be completely released when spreading apart.

[0056] The top of the petals 51 is provided with a step 57. When the petals 51 are restrained, the steps 57 form a boss on the top of the core barrel 5, onto which the restraining ring 6 is clamped. During the deployment and operation of the torpedo anchor, the restraining ring 6 clamps onto the core barrel 5 to limit the movement of the retaining ring 4. During the retrieval of the torpedo anchor, the restraining ring 6 simultaneously disengages, allowing the petals 51 to disperse and release the retaining ring 4.

[0057] When the torpedo anchor is recovered, the restraining ring 6 is released from the top of the core barrel 5 by tensioning the auxiliary cable 8 or by heat-melting the restraining ring 6 with the auxiliary cable 8. The circular hole 61 in the restraining ring 6 is used to connect the auxiliary cable 8. The restraining ring 6 can be released in various ways, such as by tensioning the restraining ring 6 to displace it from the core barrel 5 or by heat-melting it to remove its binding force on the core barrel 5.

[0058] The specific working principle of this recyclable umbrella-type torpedo anchor is:

[0059] S1. Release the torpedo anchor at the predetermined location and let it penetrate the seabed by gravity.

[0060] S2. Pull the mooring line 7 upwards, and the wing plate 2 is subjected to the force of the soil and opens to a certain angle, entering the working state.

[0061] S3. Tension the auxiliary rope 8 and pull the restraint ring 6 out from the upper part of the core tube 5. At this time, the upper part of the tube petals 51 of the core tube 5 loses its restraint, and the lower part is hinged to the torpedo anchor shell 1. It expands outward under the action of the tension of the limiting clamp 4. After expansion, the gap between the tube petals 51 of the core tube 5 becomes larger so that the limiting head 41 can pass through. At this time, the torpedo anchor becomes a recovered state.

[0062] S4. Pull the mooring line 7. The wing plate 2 transfers the tension to the towing bar 3 and the limit clamp 4, and pulls the two out of the shell hole 12 of the torpedo anchor shell 1. At this time, the wing plate 2 loses its bearing capacity. Continue to pull the mooring line 7 and recover the torpedo anchor.

[0063] The specific advantages of this recoverable umbrella-type torpedo anchor are:

[0064] 1) Traditional torpedo anchors have weak ability to resist vertical loads. This invention integrates the torpedo anchor with an umbrella structure to compensate for this deficiency.

[0065] 2) In traditional torpedo anchors, only part of the structure of partially recyclable torpedo anchors can be recycled. However, the present invention can recycle the entire torpedo anchor structure and reuse it repeatedly.

[0066] 3) The structure used for recovery is a simple mechanical structure, and the key components are relatively non-deformable, which makes it highly reliable in deep-sea environments where complex operations are difficult.

[0067] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
