The invention relates to a gravity-type anchor block device, in particular to a recyclable gravity-type anchor block device.

As the world ’s energy demand continues to grow and global energy resources are gradually depleted, advanced countries have begun to compete to develop technologies that use marine resources to generate electricity, such as offshore wind power floating platforms, ocean current power generation devices, and wave power generation devices. , And ocean temperature difference power generation devices. However, related equipment for power generation of general marine resources needs to be anchored in a specific sea area without being affected by sea wind, waves or ocean currents or drifting away from the original site. At present, there are currently anchorages used to fix the seabed. Pile foundations, anchors, and gravity anchor blocks are among the most commonly used.

Since the material of gravity anchor block is mainly composed of concrete or iron block, which is carried by its own gravity, the cable of the floating power generating device has a strong pulling force, thereby ensuring the stability of the power generating device and allowing the power generating device to be installed in the sea. The bed will not be taken away from the original site by waves and currents. However, the gravity anchor block is currently installed on the sea floor during construction. Due to the heavy weight, it sinks too quickly during installation and cannot be accurately installed at the predetermined position, which not only increases the difficulty and period of construction, but also is not conducive to personnel. In addition to the maintenance process, it is not easy to carry out subsequent recovery and decommissioning procedures, resulting in many gravity anchor blocks being abandoned and deposited on the sea floor.

Therefore, an object of the present invention is to provide a recyclable gravity anchor block device, which can not only perform installation and construction quickly and efficiently, but also have the convenience of recycling for subsequent use or decommissioning.

The branched air pipe bearing the weight and communicating with the trunk air pipe, the trunk air pipe and the branch air pipe are suitable for allowing the air intake pipe to penetrate through and make one end of the air intake pipe communicate with the accommodation space, Wherein, the seawater may be injected into the accommodation space through the trunk gas pipe to the accommodation space to settle the anchor base, and the gas may enter the accommodation space from the intake pipe to allow the seawater contained in the accommodation space to pass through the accommodation space. The trunk trachea is then discharged through the branch trachea to allow the anchor base to float.

In some embodiments, the trunk trachea has a first trunk end in communication with the accommodating space, and a second trunk end located on the opposite side of the first trunk end. A first branch end connected with the two trunk ends and a second branch end located on the opposite side of the first branch end, and the position of the second branch end is higher than the position of the first branch end.

In some implementation forms, the second trunk end of the trunk air pipe and the first trunk end of the branch air pipe are arc-shaped, so that the air intake pipe can penetrate through and make one end of the air intake pipe. And communicate with the accommodation space.

In some embodiments, a connecting structure provided on the anchor base is further included. The connecting structure includes at least one ring hole member fixed to the top wall of the anchor base.

The anchor base 1 includes a A bottom wall 11, a surrounding wall 12 extending upward from a peripheral edge of the bottom wall 11, and a top wall 13 horizontally extending from a top edge of the surrounding wall 12, and the bottom wall 11, the surrounding wall 12, and the top wall 13 cooperate with each other to define an accommodation space 14. The top wall 13 penetrates to form a personnel entrance 15 and a manhole cover 16 is arranged above the personnel entrance 15 and cooperates with the aperture of the personnel entrance 15 to cover the personnel entrance 15 15 is suitable for providing personnel to enter and leave the accommodation space 14. The ballast unit 2 is disposed in the accommodating space 14 and includes a weight 21 uniformly disposed on the bottom wall 11 of the anchor base 1. In this embodiment, the load-bearing object 21 is, for example, gravel, concrete, iron block, or other bulky filling material, to ensure the balance stability and weight of the recyclable gravity anchor block device.

The trachea unit 3 is disposed on the anchor base 1 and includes a trunk gas pipe 31 penetrating the weight 21 of the ballast unit 2 and communicating with the accommodation space 14 of the anchor base 1, and A branch gas pipe 32 penetrating the surrounding wall 12 of the anchor base 1 and penetrating the weight 21 of the ballast unit 2 and communicating with the trunk gas pipe 31. The trunk gas pipe 31 and the branch pipe The air pipe 32 is a material that is impermeable to water and air, and the trunk air pipe 31 and the branch air pipe 32 are suitable for allowing the air inlet pipe 9 to extend inward, and one end of the air inlet pipe 9 and the anchor base The accommodation spaces 14 of 1 communicate with each other. Further, the trunk gas pipe 31 has a first trunk end 311 in communication with the accommodation space 14 of the anchor base 1 and a second trunk end 312 on the opposite side of the first trunk end 311, In this embodiment, the trunk gas pipe 31 extends vertically, so the first trunk end 311 is located above the second trunk end 312. The branch trachea 32 has a first branch end 321 in communication with the second trunk end 312 of the main trunk tube 31, and a second branch end 322 on the opposite side of the first branch end 321. In this embodiment, the branch trachea 32 extends obliquely, and the height of the second branch end 322 is higher than the first branch end 321, the first trunk end 311, and the second trunk end 312. In this way, it is ensured that seawater can smoothly flow out or flow into the accommodation space 14 of the anchor base 1. On the other hand, since the height of the weight 21 is slightly lower than the first trunk end 311, the purpose is to minimize the seawater that cannot be discharged, so as to increase the aeration space of the accommodation space 14.

The air intake system 5 is, for example, an air compressor, which is disposed on a work boat 8 having a cable control pile 81 and an underwater robot control box 82, and is detachably connected to the air intake pipe 9. The tube 9 is a flexible high-pressure tube. When the recyclable gravity anchor block device has been sunk on a sea floor 7 and is to be recovered, the underwater robot control box 82 connected to the work boat 8 is remotely controlled. The robot arm of the underwater robot 4 clamps the outlet end of the air inlet pipe 9 and inserts the branch air pipe 32 from the second branch end 322, and further advances to the trunk air pipe 31, so that the inlet pipe 9 reaches The accommodating space 14 filled with seawater is in a state shown in FIG. 2. The air intake system 5 is used to provide gas to the accommodation space 14 of the anchor base 1 via the air intake pipe 9. The air intake system 5 includes a gas control valve 51. The gas control valve 51 is disposed beside the air intake system 5 and communicates with the air intake pipe 9. The gas control valve 51 is located in the recyclable gravity anchor block device. When the gas expands during the ascent process, it is suitable for releasing gas to allow seawater to enter the accommodating space 14 of the anchor base 1 so as to keep the buoyancy from being excessive. The connecting structure 6 is disposed on the anchor base 1 and includes four ring hole members 61 fixed to the top wall 13 and the surrounding wall 12 of the anchor base 1 and a ring hole connected to the ring hole 61 respectively. The cable 62 of the component 61 and the other end of the cable 62 are connected to the cable control pile 81 on the work boat 8. The number and arrangement of the ring hole members 61 are not limited to the above.

Specifically, the recyclable gravity anchor block device is disposed on the sea floor 7 and is connected to the power generating device or platform on the sea through the cable 62 of the connection structure 6, so that the power generating device or platform on the sea can be stably anchored. Sting in the sea. Since the anchor base 1 is a hollow structure, when it is necessary to sink the recyclable gravity anchor block device into the seabed 7, the air inlet pipe 9 is first inserted into the air pipe unit 3, as shown in FIG. 3 It is shown that seawater is poured into the accommodation space 14 from the second branch end 322, so that the set of the recyclable gravity anchor block device starts to sink, so that seawater can be drawn from the second branch end 322 of the branch air pipe 32 It is injected into the containing space 14 through the trunk gas pipe 31, so that the anchorage base 1 is settled. Therefore, the recyclable gravity anchor block device can sit on the bottom 7. On the other hand, when it is necessary to recover the recyclable gravity anchor block device, as shown in FIG. 2, the intake pipe 9 may be sequentially extended through the branch air pipe 32 and the main air pipe 31, and the The air outlet end of the air inlet pipe 9 communicates with the accommodation space 14 of the anchor base 1, and the gas enters the accommodation space 14 from the air inlet pipe 9, so that the space accommodated in the anchor base 1 is accommodated. The seawater in the installation space 14 is pushed by the pressure of the injected air and flows out from the trunk air pipe 31, and then is discharged through the second branch end 322 of the branch air pipe 32, so that the anchor base 1 floats. Therefore, The recyclable gravity anchor block device can float on the sea level, and after the air inlet pipe 9 is removed from the recyclable gravity anchor block device, the state shown in FIG. 3 is displayed.

In this embodiment, the contact surface between the bottom wall 11 of the anchor base 1 and the sea floor 7 can be designed differently according to the characteristics of the bottom texture of the sea floor 7 and is not limited to a smooth surface or a rough surface. Surface, you can also perform additional anti-slip processing. For example, when the bottom of the seabed is sediment, the contact surface between the bottom wall 11 of the anchor base 1 and the bottom 7 can be designed to be uneven. For example, when the bottom of the seabed is rock, the anchor can be made. A soft pad is installed on the contact surface between the bottom wall 11 of the base 1 and the bottom 7. In addition, the filling height of the weight 21 of the ballast unit 2 in the accommodating space 14 of the anchor base 1 is about 1/3 of the surrounding wall 12 of the anchor base 1. Keeping the center of gravity position of the anchor base 1 below the floating center position, the recyclable gravity anchor block device can resist the sway of the ocean current within the limit tolerable, and will not lean to one side and cause the anchor base 1 presents a tilted state to ensure the balance and stability of the recyclable gravity anchor block device. Therefore, the power generating device or platform on the sea can stand firmly in the target sea area. It should be particularly noted that the design and manufacturer should be able to adjust and combine according to the actual use needs, and the setting method of the anchor base 1 is not limited to the content disclosed in this embodiment.

Further, in order to facilitate the operator to insert and pass the air inlet pipe 9 through the branch air pipe 32 and the main air pipe 31, and at the same time let one end of the air pipe 9 pass through the container of the anchor base 1. In the space 14, in this embodiment, the second trunk end 312 of the trunk air pipe 31 and the first trunk end 321 of the branch air pipe 32 have an arc shape design, and the second branch end 322 It is horn-shaped, so that the air inlet pipe 9 can easily penetrate and extend inside, and one end of the air inlet pipe 9 can communicate with the accommodation space 14. In addition, the position of the second branch end 322 must be higher than the position of the first branch end 321 to prevent the regenerative gravity anchor block device from sinking to the bottom of the sea 7 when the branch trachea The opening of 32 (that is, the second branch end 322) is buried. In particular, it should be noted that the designer and the manufacturer can adjust according to the actual use needs. The arrangement of the trachea unit 3 is not based on this embodiment. The disclosure is limited, and those who can also achieve the effect of the trachea unit 3 are regarded as conventional changes in this embodiment.

Generally speaking, during the construction of the recyclable gravity anchor block device, firstly, the anchor base 1 is built in a dock on the coast (not shown in the figure). After the device is properly completed, the person can import and export 15 The load-bearing object 21 is filled into the accommodation space 14 of the anchor base 1 by a conveyor belt, a sand pump or other methods. Then, tow the recyclable gravity anchor block device to the installation target sea area through a construction ship, use the cable 62 to connect and fix the power generation device or platform to be anchored, and insert the air inlet pipe 9 to the air pipe unit 3, Seawater is poured into the accommodating space 14 from the second branch end 322, so that the retrievable gravity anchor block device starts to sink, and finally, the air inlet pipe 9 is removed. In particular, in order to allow the air remaining in the accommodating space 14 to be exhausted as much as possible when the anchor base 1 sinks to the bottom, an appropriate size buoyancy member is added to the outlet of the intake pipe 9 (not shown in the figure). (Out), so that the outlet of the air inlet pipe 9 is kept on the inner water surface of the accommodating space 14. During the installation and retrieval process, the work boat 8 needs to operate the cable 62 to hold the anchor base 1 in order to control its movement.

The air inlet pipe 9 can be temporarily inserted before the retrievable gravity anchor block device sinks. When the retrievable gravity anchor block device is settled on the seabed 7, it can be transported by the air intake system 5. The gas enters the air inlet pipe 9 and passes through the gas into the accommodation space 14 of the anchorage base 1 to increase the buoyancy of the recyclable gravity anchor block device. As the water depth increases, the air is compressed and the buoyancy becomes smaller. Control the sinking speed of the recyclable gravity anchor block device, and adjust the anchorage anchorage point of the recyclable gravity anchor block device. If the recyclable gravity anchor block device is to be recovered and decommissioned, the air inlet pipe 9 is inserted into the air pipe unit 3, and the gas is delivered to the anchor base 1 through the air inlet system 5. In the accommodating space 14, the seawater originally contained in the accommodating space 14 of the anchorage base 1 is discharged by the infiltration of gas, so that the recyclable gravity anchor block device slowly rises toward the sea level. As the depth gradually decreases, the pressure in the accommodating space 14 of the anchor base 1 also decreases, and excess gas is naturally released from the opening of the branch air pipe 32, or the air pipe unit 3 passes through. The air inlet pipe 9 is released by adjusting the gas control valve 51 and keeps the recyclable gravity anchor block device to continue to float until the recyclable gravity anchor block device floats at sea level.

Referring to FIG. 4, there is a second embodiment of the present invention. The overall structure and use method of the recyclable gravity anchor block device are substantially the same as those of the first embodiment, and the second embodiment is similar to the first embodiment. The main difference is that in this embodiment, the ballast unit 2 further includes a spacer 22 covering the weight 21, because in this embodiment, the weight 21 is, for example, gravel or other specific gravity. In the case of particles, the spacer 22 can prevent the weight 21 from rolling down to the opening of the trunk air pipe 31 (that is, the first trunk end 311), thereby preventing the air pipe unit 3 from being blocked.

In summary, the recyclable gravity anchor block device of the present invention uses the air inlet pipe 9 capable of being filled with gas to change the recyclable gravity anchor block by introducing or discharging seawater in the sea. Floating state of the device. On the one hand, seawater can be injected from the branch air pipe 32 through the main air pipe 31 into the accommodation space 14 to settle the anchor base 1; on the other hand, gas can enter the accommodation space 14 from the intake pipe 9 The seawater contained in the accommodation space 14 is passed through the trunk air pipe 31 and then discharged through the branch air pipe 32 to float the anchor base 1, and the recyclable gravity anchor block device can not only assist personnel to quickly and effectively The installation and construction, as well as the convenience of recyclable operation, can indeed achieve the purpose of cost invention.

However, the above are only examples of the present invention.
