Description
Technical Field
[0001] The utility model belongs to the technical field of suction anchors, and particularly relates to a novel suction anchor device. Background Technique
[0002] An anchor generally refers to a ship anchor, which is the main component of the anchoring equipment. It is an iron-made ship-stopping device connected to the ship by a chain. Throwing the anchor to the bottom of the water can make the ship stop steadily. The traditional anchor has relatively less reliable grip than the suction anchor, and it is more troublesome to recover the anchor. Moreover, when the suction anchor is in use, during the process of the anchor barrel sinking into the soil, the soil body surges into the pipe to form a soil plug effect. For the surging soil body, the anchor barrel lacks the function of blocking, and the soil body entering the injection and drainage pipe will affect the subsequent injection and drainage effect. Content of the Utility Model
[0003] The purpose of the utility model is to provide a novel suction anchor device to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A novel suction anchor device includes a suction anchor body, which includes an anchor barrel and a top cover. The top cover is connected to the top end of the anchor barrel. A reinforcing mechanism is connected to the middle of the upper end of the top cover. Suction anchor lifting points are symmetrically arranged at the upper end of the reinforcing mechanism. The top end of the top cover is symmetrically communicated with a water guide pipe. One side of the upper end of the anchor barrel is connected with an anchoring point. A water injection and drainage mechanism is arranged in the middle of the upper end of the anchor barrel;
[0006] The reinforcing mechanism includes reinforcing ribs, primary reinforcing members and secondary reinforcing members. The reinforcing ribs are connected to the middle of the top end of the top cover. The primary reinforcing members cover the upper end and the ends of the reinforcing ribs. The secondary reinforcing members are connected to the upper end of the top cover, and both ends of the secondary reinforcing members are connected to the reinforcing ribs;
[0007] The water injection and drainage mechanism includes a cavity, a driving motor, a driving lead screw, an isolation circular plate, a lifting circular plate and a threaded hole. The cavity is opened in the middle of the bottom end of the reinforcing rib. The driving motor is arranged in the cavity and is fixedly connected to the middle end of the top of the top cover through a positioning bolt. The top end of the driving lead screw is connected to the output end of the bottom of the driving motor. The isolation circular plate is arranged above the inner cavity of the anchor tube. The lifting circular plate is arranged above the isolation circular plate. The threaded hole is opened in the middle of the lifting circular plate and penetrates through the lifting circular plate up and down. The bottom end of the driving lead screw penetrates through the top cover and the threaded hole and is connected to the isolation circular plate through a bearing. The outer wall of the driving lead screw is threadedly connected to the threaded hole through a thread. When the driving motor is started to drive the driving lead screw to rotate, when the drainage function needs to be realized, the lifting circular plate is raised, and the water in the chamber between the upper end of the lifting circular plate and the anchor tube is extruded by the water guide pipe. When the upper surface of the lifting circular plate contacts the top cover, the water is emptied. The chamber between the bottom surface of the lifting circular plate and the isolation circular plate forms a negative pressure. The pressure outside the anchor tube is greater than the pressure inside, and a downward pressure is formed at the top of the anchor tube. The more water is discharged from the anchor tube, the greater the pressure difference between the inside and the outside, that is, the greater the additional downward pressure applied to the anchor tube. When the pressure overcomes the mud penetration resistance of the anchor tube, the anchor tube continues to sink until it reaches the predetermined depth. On the contrary, when the water injection function needs to be realized, the lifting circular plate is lowered. As the lifting circular plate descends, the water outside the anchor tube flows into the anchor tube through the water guide pipe. When the bottom surface of the lifting circular plate contacts the isolation circular plate, a positive pressure will be generated, that is, an upward pulling force will be generated to pull the anchor tube out of the seabed;
[0008] The water injection and drainage mechanism further includes a first-stage trigger switch and a second-stage trigger switch. The first-stage trigger switch is embedded in the top of the isolation circular plate, and the second-stage trigger switch is embedded in the bottom of the top cover. When the lifting circular plate rises and contacts the second-stage trigger switch, the second-stage trigger switch transmits a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the driving motor to turn off. When the lifting circular plate descends and contacts the first-stage trigger switch, the first-stage trigger switch transmits a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the driving motor to turn off. Thus, through the first-stage trigger switch and the second-stage trigger switch, the driving motor can be timely turned off to prevent the driving motor from being damaged.
[0009] Preferably, the outer wall of the isolation circular plate is connected to the inner wall of the anchor tube, ensuring the isolation effect of the upper and lower spaces inside the anchor tube by the isolation circular plate. When the soil plugging effect occurs, the incoming soil is not easy to enter the water guide pipe, thereby ensuring the water injection and drainage effect of the water guide pipe. The outer wall of the lifting circular plate is in sliding fit with the anchor tube, ensuring the sealing between the outer wall of the lifting circular plate and the anchor tube and making it convenient for the lifting circular plate to lift, so as to ensure the water lifting effect of the lifting circular plate and cooperate with the water guide pipe to better realize the water injection and drainage function.
[0010] Preferably, communication ports are symmetrically opened at the front and rear of the upper end of the lifting circular plate, and the bottom ends of the communication ports penetrate through the lifting circular plate.
[0011] Preferably, limiting round rods are symmetrically connected to the front and rear of the bottom end of the top cover, and the bottom ends of the limiting round rods penetrate through the communication ports and are connected to the isolation round plate, restricting the lifting round plate while not affecting its lifting, and preventing the lifting round plate from rotating with the rotation of the driving lead screw.
[0012] Preferably, the reinforcing rib includes a circular middle part and strip-shaped end parts. The circular middle part is located in the middle of the top of the top cover, and the strip-shaped end parts are circumferentially and arrayedly connected to the outer wall of the circular middle part, and there are eight groups of strip-shaped end parts. While ensuring the strengthening effect of the reinforcing rib, the material consumption of the reinforcing rib is reduced, the production cost of the reinforcing rib and the self-weight of the reinforcing rib are lowered.
[0013] Preferably, both ends of the secondary strengthening member are respectively connected to the strip-shaped end parts. There are two secondary strengthening members with different specifications, and taking two different secondary strengthening members as a group, eight groups of secondary strengthening members are installed and are respectively located between adjacent two strip-shaped end parts, so as to further strengthen the strength of the top cover in cooperation with the reinforcing rib.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the water guide pipe and in cooperation with the water injection and drainage mechanism, water injection and drainage in the anchor barrel are realized, so that rapid anchoring and unanchoring can be achieved through the positive and negative pressure methods. And through the primary trigger switch and the secondary trigger switch, after the water is emptied and filled, information is transmitted to the peripheral device in time, and the driving motor is controlled by the peripheral device to be closed in time. At the same time, the setting of the isolation round plate can prevent the incoming soil mass from interfering with the water injection and drainage effect when the soil plug effect occurs.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Example 1
[0021] Please refer to Figures 1 - 4 As shown in the figure, a new type of suction anchor device includes a suction anchor body, which comprises an anchor barrel 1 and a top cover 2. The top cover 2 is connected to the top end of the anchor barrel 1. In the middle of the upper end of the top cover 2, a strengthening mechanism is connected. On the upper end of the strengthening mechanism, suction anchor suspension points 3 are symmetrically arranged. On the top of the top cover 2, water guide pipes 4 are symmetrically communicated. On the upper side of one side of the anchor barrel 1, an anchoring point 5 is connected. In the middle of the upper end of the anchor barrel 1, a water injection / drainage mechanism is arranged;
[0022] The strengthening mechanism includes strengthening ribs 6, primary strengthening members 7 and secondary strengthening members 8. The strengthening ribs 6 are connected to the middle of the top end of the top cover 2. The primary strengthening members 7 cover the upper end and the ends of the strengthening ribs 6. The secondary strengthening members 8 are connected to the upper end of the top cover 2, and both ends of the secondary strengthening members 8 are connected to the strengthening ribs 6;
[0023] The water injection / drainage mechanism includes a cavity 9, a driving motor 10, a driving lead screw 11, an isolation circular plate 12, a lifting circular plate 13 and a threaded hole 14. The cavity 9 is opened in the middle of the bottom end of the strengthening ribs 6. The driving motor 10 is arranged in the cavity 9, and the driving motor 10 is fixedly connected to the middle of the top of the top cover 2 through a positioning bolt. The top end of the driving lead screw 11 is connected to the output end of the bottom of the driving motor 10. The isolation circular plate 12 is arranged above the inner cavity of the anchor barrel 1. The lifting circular plate 13 is arranged above the isolation circular plate 12. The threaded hole 14 is opened in the middle of the lifting circular plate 13, and the threaded hole 14 penetrates through the lifting circular plate 13 up and down. The bottom end of the driving lead screw 11 penetrates through the top cover 2 and the threaded hole 14, and is connected to the isolation circular plate 12 through a bearing. The outer wall of the driving lead screw 11 is threadedly connected to the threaded hole 14 through threads. When the driving motor 10 is started to drive the driving lead screw 11 to rotate, when the drainage function needs to be realized, the lifting circular plate 13 is lifted, and the water in the chamber between the upper end of the lifting circular plate 13 and the anchor barrel 1 is extruded through the water guide pipe. When the upper surface of the lifting circular plate 13 contacts the top cover 2, the water is emptied. And a negative pressure is formed in the chamber between the bottom surface of the lifting circular plate 13 and the isolation circular plate 12. The pressure outside the anchor barrel 1 is greater than the pressure inside. A downward pressure is formed at the top of the anchor barrel 1. The more water is discharged from the anchor barrel 1, the greater the pressure difference between the inside and the outside is, that is, the greater the additional downward pressure applied to the anchor barrel 1 is. When the pressure overcomes the mud penetration resistance of the anchor barrel 1, the anchor barrel 1 continues to sink until it reaches the predetermined depth. On the contrary, when the water injection function needs to be realized, the lifting circular plate 13 is lowered. As the lifting circular plate 13 descends, the water outside the anchor barrel 1 flows into the anchor barrel 1 through the water guide pipe 4. When the bottom surface of the lifting circular plate 13 contacts the isolation circular plate 12, a positive pressure will be generated, that is, an upward pulling force is generated to pull the anchor barrel 1 out of the seabed;
[0024] The water injection and drainage mechanism further includes a primary trigger switch 15 and a secondary trigger switch 16. The primary trigger switch 15 is embedded in the top of the isolation circular plate 12, and the secondary trigger switch 16 is embedded in the bottom of the top cover 2. When the lifting circular plate 13 rises and contacts the secondary trigger switch 16, the secondary trigger switch 16 transmits a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the driving motor 10 to turn off. When the lifting circular plate 13 descends and contacts the primary trigger switch 15, the primary trigger switch 15 transmits a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the driving motor 10 to turn off. Thus, through the primary trigger switch 15 and the secondary trigger switch 16, the driving motor 10 can be timely turned off to prevent the driving motor 10 from being damaged.
[0025] Reference Figure 3 and Figure 4 As shown, the outer wall of the isolation circular plate 12 is connected to the inner wall of the anchor barrel 1, ensuring the isolation effect of the upper and lower spaces inside the anchor barrel 1 by the isolation circular plate 12. When the soil plug effect occurs, the incoming soil mass is not easily introduced into the water conduit 4, thereby ensuring the water injection and drainage effect of the water conduit 4. The outer wall of the lifting circular plate 13 is in sliding fit with the anchor barrel 1, ensuring the sealing between the outer wall of the lifting circular plate 13 and the anchor barrel 1 while facilitating the lifting of the lifting circular plate 13, thus ensuring the water lifting effect of the lifting circular plate 13 and better realizing the water injection and drainage function in cooperation with the water conduit 4.
[0026] Reference Figure 3 As shown, communication ports 17 are symmetrically arranged at the front and rear of the upper end of the lifting circular plate 13, and the bottom ends of the communication ports 17 penetrate through the lifting circular plate 13.
[0027] Reference Figure 3 and Figure 4 As shown, limiting circular rods 18 are symmetrically connected to the bottom end of the top cover 2 at the front and rear, and the bottom ends of the limiting circular rods 18 penetrate through the communication ports 17 and are connected to the isolation circular plate 12, restricting the lifting circular plate 13 without affecting its lifting, and preventing the lifting circular plate 13 from rotating with the rotation of the driving lead screw 11.
[0028] Reference Figures 1 - 3 As shown, the reinforcing rib 6 includes a circular middle part and strip-shaped end parts. The circular middle part is located in the middle of the top of the top cover 2, and the strip-shaped end parts are circumferentially arranged and connected to the outer wall of the circular middle part, and there are eight groups of strip-shaped end parts. While ensuring the strengthening effect of the reinforcing rib 6, the material consumption of the reinforcing rib 6 is reduced, and the production cost and self-weight of the reinforcing rib 6 are lowered.
[0029] Reference Figures 1 - 3As shown, both ends of the secondary reinforcing member 8 are respectively connected to the strip-shaped ends. There are two secondary reinforcing members 8 with different specifications, and taking two different secondary reinforcing members 8 as a group, eight groups of secondary reinforcing members 8 are installed and are respectively located between adjacent two strip-shaped ends, so as to further strengthen the strength of the top cover 2 in cooperation with the reinforcing rib 6.
[0030] Working principle: Lift the suction anchor body and slowly lower it into the water until it is above the seabed. When the suction anchor body is placed on the seabed, slowly release the tension on the hook, and let part of the anchor barrel 1 sink into the mud by its own weight. When the internal and external water pressures and the self-weight of the anchor barrel 1 reach equilibrium, the anchor barrel 1 stops sinking. Start the drive motor 10 to drive the drive screw 11 to rotate. When the drainage function needs to be realized, raise the lifting circular plate 13 to squeeze the water in the chamber between the upper end of the lifting circular plate 13 and the anchor barrel 1 out through the water guide pipe. When the upper surface of the lifting circular plate 13 contacts the top cover 2, the water is emptied. The chamber between the bottom surface of the lifting circular plate 13 and the isolation circular plate 12 forms a negative pressure, and the external pressure of the anchor barrel 1 is greater than the internal pressure, forming a downward pressure on the top of the anchor barrel 1. The more water is discharged from the anchor barrel 1, the greater the pressure difference between the inside and outside, that is, the greater the additional downward pressure applied to the anchor barrel 1. When the pressure overcomes the resistance of the anchor barrel 1 entering the mud, the anchor barrel 1 continues to sink until it reaches the predetermined depth. On the contrary, when the drainage function needs to be realized, lower the lifting circular plate 13. As the lifting circular plate 13 descends, the water outside the anchor barrel 1 flows into the anchor barrel 1 through the water guide pipe 4. When the bottom surface of the lifting circular plate 13 contacts the isolation circular plate 12, a positive pressure will be generated, that is, an upward pulling force is generated to pull the anchor barrel 1 out of the seabed. When the lifting circular plate 13 rises and contacts the secondary trigger switch 16, the secondary trigger switch 16 transmits a signal to the external device terminal. The external device terminal receives the signal and controls the drive motor 10 to turn off. When the lifting circular plate 13 descends and contacts the primary trigger switch 15, the primary trigger switch 15 transmits a signal to the external device terminal. The external device terminal receives the signal and controls the drive motor 10 to turn off. Thus, through the primary trigger switch 15 and the secondary trigger switch 16, the drive motor 10 can be turned off in time to prevent the drive motor 10 from being damaged.
