Description

Technical Field

[0001] This utility model relates to the field of anchor structure technology, specifically a plow-shaped anchor device. Background Technology

[0002] Anchors play an important role in many fields. Their core function is to provide fixation and stability. In the field of navigation, anchors are used to stabilize ships in specific waters, resist the effects of wind, waves and currents, and ensure the safety of ships. At the same time, in marine engineering and aquaculture, anchors fix platforms, cages or monitoring equipment to ensure their normal operation in complex marine environments and reduce losses caused by displacement.

[0003] In existing technologies, traditional anchors mainly consist of anchor claws and anchor shanks. The anchor claws are used to penetrate the seabed soil to provide gripping force, while the anchor shank connects to the anchor chain and transmits the tension to the entire structure. The anchor claws and anchor shanks work together to achieve reliable positioning.

[0004] However, when using traditional anchors, because the anchor and anchor chain are rigidly connected, stress concentration is prone to occur in complex sea conditions, causing excessive instantaneous tension on the anchor chain, which can lead to the anchor claws coming off or breaking. To address this problem, this utility model proposes a plow-shaped anchor device. Utility Model Content

[0005] The purpose of this invention is to provide a plow-shaped anchor device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plow-shaped anchor device, comprising: an anchor claw, a connecting handle disposed inside the anchor claw, an anchor handle disposed at one end of the connecting handle, a connecting frame fixedly installed inside the anchor claw, a connecting handle being inserted into the connecting frame, and a buffer spring disposed between the anchor handle and the connecting handle.

[0007] Preferably, the anchor claw includes a conical claw, an auxiliary frame, and a mounting plate. The mounting plate is fixedly installed inside the conical claw, the auxiliary frame is fixedly installed on the surface of the mounting plate away from the conical claw, and a connecting frame is fixedly installed on the surface of the mounting plate.

[0008] Preferably, a connecting pipe is provided on the upper surface of the connecting frame, and fixed bearings are fixedly installed on the inner walls of both ends of the connecting pipe. The outer ring surface of the fixed bearing is fixedly connected to the inner wall of the connecting pipe, and a limit groove is provided on the side wall of the connecting frame.

[0009] Preferably, the connecting handle includes a connecting assembly and a connecting rod. The connecting assembly includes a connecting shaft, a limiting shaft, and a fixing frame. The fixing frame is fixedly installed at one end of the connecting rod. The connecting shaft is fixedly inserted into the upper end of the fixing frame. The connecting shaft is placed inside the connecting tube. The outer walls of both ends of the connecting shaft are fixedly connected to the inner ring surface of the fixing bearing. The limiting shaft is fixedly inserted into the lower end of the fixing frame. The limiting bearing is fixedly installed on the outer walls of both ends of the limiting shaft. The inner ring surface of the limiting bearing is fixedly connected to the outer walls of both ends of the limiting shaft. The limiting bearing is stuck in the limiting groove.

[0010] Preferably, the angle between the connecting rod and the anchor claw is maintained between 40° and 50°, and a buffer groove is provided at the end of the connecting rod away from the anchor claw. A buffer spring is fixedly installed on the inner wall of the buffer groove at the end away from the anchor claw.

[0011] Preferably, the anchor handle has an inner cavity near the connecting handle end, and a clip is fixedly installed on the side wall of one end of the inner cavity. The clip can be inserted into the buffer groove, and one end of the buffer spring in the buffer groove abuts against the surface of the clip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention proposes a plow-type anchor device. In use, the entire device can be thrown out. When the device contacts the seabed and moves forward, the cone-shaped anchor claws engage with the soil. Simultaneously, the connecting shank rotates within the connecting frame, allowing the anchor claws to penetrate deeper into the soil as the vessel moves. When the anchor shank and anchor chain are taut, the buffer spring located between the anchor shank and connecting shank undergoes elastic deformation, effectively absorbing and dispersing the impact force caused by waves or external forces during vessel movement. This prevents excessive instantaneous tension on the anchor claws from the soil, thus avoiding the problem of the anchor claws detaching or breaking due to excessive instantaneous tension.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a plow-shaped anchor device, including: an anchor claw 1, a connecting handle 2 provided inside the anchor claw 1, an anchor handle 3 provided at one end of the connecting handle 2, a connecting frame 4 fixedly installed inside the anchor claw 1, the connecting handle 2 being inserted into the connecting frame 4, and a buffer spring 5 provided between the anchor handle 3 and the connecting handle 2.

[0023] When in use, the entire device can be thrown out. When the device contacts the seabed soil and moves forward, the anchor claw 1, due to its conical structure, can bite into the soil. At this time, the connecting handle 2 will also rotate in the connecting frame 4, allowing the anchor claw 1 to penetrate deeper into the soil during the movement of the ship. When the anchor handle 3 and the anchor chain are in a taut state, the buffer spring 5 located between the anchor handle 3 and the connecting handle 2 can undergo elastic deformation, which can effectively absorb and disperse the impact force caused by waves or external forces during the movement of the ship, and prevent the anchor chain from exerting excessive instantaneous tension on the anchor claw 1. This avoids the problem of the anchor claw 1 coming off the soil or breaking due to excessive instantaneous tension of the anchor chain.

[0024] Example 2: Based on Example 1, in order to better engage the anchor into the soil layer, an anchor claw 1 is provided. The anchor claw 1 includes a conical claw 6, an auxiliary frame 7 and an installation plate 8. The installation plate 8 is fixedly installed inside the conical claw 6. The auxiliary frame 7 is fixedly installed on the surface of the installation plate 8 away from the conical claw 6. The connecting frame 4 is fixedly installed on the surface of the installation plate 8.

[0025] In order to make the anchor claw 1 better engage in the soil layer, the cone claw 6 in the anchor claw 1 forms an acute angle with the ground. At the same time, the end of the cone claw 6 near the soil layer is relatively sharp and can be deeply inserted into the soil layer. Furthermore, an auxiliary frame 7 is fixedly installed on the surface of the cone claw 6 near the ground layer. The auxiliary frame 7 can always prevent the cone claw 6 from sticking to the soil layer, thereby allowing the cone claw 6 to engage in the soil layer better.

[0026] A connecting pipe 10 is provided on the upper surface of the connecting frame 4. Fixed bearings 11 are fixedly installed on the inner walls of both ends of the connecting pipe 10. The outer ring surface of the fixed bearings 11 is fixedly connected to the inner wall of the connecting pipe 10. A limit groove 9 is opened on the side wall of the connecting frame 4.

[0027] The connecting handle 2 is always locked inside the connecting tube 10 of the connecting frame 4 via the connecting shaft 15, and the limiting shaft 16 is locked in the limiting groove 9 opened on the side wall of the connecting frame 4. The limiting shaft 16 can be displaced along the limiting groove 9, so that the angle between the connecting handle 2 and the anchor claw 1 is always kept within 40°-50°. The anchor claw 1 can maintain the optimal force angle in this angle state, avoiding the problem of insufficient gripping force or difficulty in insertion caused by the angle being too large or too small. This allows the anchor claw 1 to be more firmly embedded in the soil layer, thereby enhancing the overall stability.

[0028] Example 3: Based on Example 2, a connecting handle 2 is provided to avoid excessive instantaneous tension on the entire device. The connecting handle 2 includes a connecting assembly 13 and a connecting rod 14. The connecting assembly 13 includes a connecting shaft 15, a limiting shaft 16, and a fixing frame 17. The fixing frame 17 is fixedly installed at one end of the connecting rod 14. The connecting shaft 15 is fixedly inserted into the upper end of the fixing frame 17. The connecting shaft 15 is placed inside the connecting tube 10. The outer walls of both ends of the connecting shaft 15 are fixedly connected to the inner ring surface of the fixed bearing 11. The limiting shaft 16 is fixedly inserted into the lower end of the fixing frame 17. The outer walls of both ends of the limiting shaft 16 are fixedly connected to the inner ring surface of the fixed bearing 11. A limiting bearing 18 is fixedly installed, and the inner ring surface of the limiting bearing 18 is fixedly connected to the outer walls of both ends of the limiting shaft 16. The limiting bearing 18 is locked in the limiting groove 9. The angle between the connecting rod 14 and the anchor claw 1 is maintained between 40° and 50°. A buffer groove 19 is opened at the end of the connecting rod 14 away from the anchor claw 1. A buffer spring 5 is fixedly installed at the end of the inner wall of the buffer groove 19 away from the anchor claw 1. An inner cavity is opened at the end of the anchor handle 3 near the connecting handle 2. A clamp 12 is fixedly installed on the side wall of one end of the inner cavity. The clamp 12 can be locked into the buffer groove 19. One end of the buffer spring 5 in the buffer groove 19 abuts against the surface of the clamp 12.

[0029] During use, when the anchor chain is subjected to a strong tensile force, the locking piece 12 in the inner cavity of one end of the anchor handle 3 is locked in the buffer groove 19, and the buffer groove 19 is equipped with a buffer spring 5. When the anchor handle 3 is subjected to the anchor chain, the locking piece 12 will act on the buffer spring 5. Under the action of the buffer spring 5, part of the tensile force can be effectively absorbed and dispersed, reducing the impact on the connecting rod 14 and the anchor claw 1, thereby avoiding the risk of the anchor claw 1 being damaged or dislodged due to excessive tensile force on the entire device.

[0030] Working principle: In actual use, the entire device can be thrown out. When the device contacts the seabed and moves forward, the anchor claw 1, due to its conical structure, can bite into the soil. At this time, the connecting handle 2 will also rotate in the connecting frame 4, allowing the anchor claw 1 to penetrate deeper into the soil during the movement of the ship. When the anchor handle 3 and the anchor chain are in a taut state, the buffer spring 5 located between the anchor handle 3 and the connecting handle 2 can undergo elastic deformation, which can effectively absorb and disperse the impact force caused by waves or external forces during the movement of the ship, and prevent the anchor chain from exerting excessive instantaneous tension on the anchor claw 1. This avoids the problem of the anchor claw 1 coming off the soil or breaking due to excessive instantaneous tension of the anchor chain.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
