Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 As shown, a pile foundation measuring device for marine structures includes a bottom plate 1 and a connecting plate 2;

[0028] Arc-shaped slotted grooves 4 are provided on the opposite sides of the bottom plate 1 and the connecting plate 2. Connecting components 3 are arranged on the front and back surfaces between the bottom plate 1 and the connecting plate 2. A mounting plate 5 is arranged on the top of the bottom plate 1. A mounting component 6 is arranged between the mounting plate 5 and the bottom plate 1. A placing groove 8 is provided on the top of the bottom plate 1. A clamping component 7 is arranged inside the placing groove 8. A measuring component 9 is jointly arranged inside the placing groove 8. During work, first, the slotted grooves 4 of the bottom plate 1 and the connecting plate 2 are assembled with the pile foundation, and the bottom plate 1, the connecting plate 2 and the external pile foundation are installed through the connecting component 3. Then, the pile foundation, the bottom plate 1 and the connecting plate 2 are inserted into the water together. After insertion, the measuring component 9 measures the penetration depth of the pile foundation. At the same time, the mounting component 6 facilitates the disassembly of the mounting plate 5, the measuring component 9 and the bottom plate 1, and also facilitates the disassembly and maintenance of the measuring component 9, so that the device can meet more usage requirements and has strong practicability. The parts inside the measuring component 9 can also be clamped and installed through the clamping component 7, which is convenient for disassembly, maintenance and replacement.

[0029] A through hole 10 penetrating up and down is provided on the left side inside the bottom plate 1 and on the right side inside the connecting plate 2; during operation, it is convenient for an external steel chain to penetrate through the through hole 10 to tie the bottom plate 1 and the connecting plate 2, so as to facilitate pulling the bottom plate 1 and the connecting plate 2 out of the water after the measurement is completed.

[0030] The connecting component 3 includes fixing plates 301 fixedly connected to the left sides of the front and rear surfaces of the connecting plate 2. A through jack 302 is provided on the left side inside the fixing plate 301. Mounting holes 304 are provided on the right sides of the front and rear surfaces of the bottom plate 1. An electric push rod 305 is fixedly installed inside the mounting hole 304. The output end of the electric push rod 305 is fixedly connected to a plug rod 303, and the plug rod 303 is inserted into the jack 302; during operation, the electric push rod 305 drives the plug rod 303 to move and be inserted into the jack 302 to connect the bottom plate 1 and the connecting plate 2. And when the measurement is completed, the electric push rod 305 drives the plug rod 303 to move, and then the plug rod 303 moves out of the jack 302, so that the connection between the bottom plate 1 and the fixing plate 301 disappears, and the bottom plate 1 and the connecting plate 2 can be separated.

[0031] The clamping component 7 includes inner grooves 702 provided on the front and rear surfaces inside the placement groove 8. A slider 704 is slidably connected inside the inner groove 702. A third spring 703 is fixedly connected between the slider 704 and the inner groove 702. One side of the slider 704 is fixedly connected to a clamping rod 705. One end of the clamping rod 705 is fixedly connected to an L-shaped clamping plate 701; during operation, by moving the L-shaped clamping plate 701 to drive the clamping rod 705 to move, and after the clamping rod 705 moves, it drives the slider 704 to slide inside the inner groove 702, and when the slider 704 slides, it squeezes the third spring 703 to make the third spring 703 have a rebounding force. Then, the rebounding force of the third spring 703 enables the two L-shaped clamping plates 701 to clamp an object.

[0032] The measurement component 9 includes a displacement sensor 901 disposed between the two L-shaped clamping plates 701. A signal transceiver is provided inside the displacement sensor 901. A measuring rod 902 is fixedly connected to the right side of the mounting plate 5. A vertically penetrating groove 903 is formed at the right end of the measuring rod 902. A distance measuring roller 904 is rotatably connected inside the groove 903. During operation, the bottom plate 1 and the connecting plate 2 are installed on the outer surface of an external pile foundation through the connecting component 3. When the pile foundation sinks to the seabed, the bottom plate 1 and the connecting plate 2 will encounter resistance when they meet the seabed soil mass, causing the bottom plate 1 and the connecting plate 2 to fit on the seabed surface and no longer sink. Then the pile foundation continues to penetrate into the soil. At this time, a relative displacement will be generated between the pile foundation and the measurement component 9, thereby driving the distance measuring roller 904 to rotate. And the displacement sensor 901 will convert the number of turns of the distance measuring roller 904 into displacement data, so as to calculate the penetration depth of the pile foundation. And the measured data is sent to an external workbench through the signal transceiver. At the same time, the displacement sensor 901 is clamped and installed through the L-shaped clamping plate 701, and it is convenient for disassembly, inspection, replacement and reinstallation of the displacement sensor 901.

[0033] The installation component 6 includes a plurality of uniformly distributed installation grooves 605 formed at the top of the bottom plate 1. An insertion plate 606 is inserted into the installation groove 605, and the top of the insertion plate 606 is fixedly connected to the bottom of the mounting plate 5. A through chute 611 is formed inside the insertion plate 606. Installation rods 609 are slidably connected to both the left and right sides inside the chute 611. A second spring 610 is sleeved on the outer surface of the installation rod 609. Slots 612 are formed on both the left and right sides inside the installation groove 605, and the ends of the installation rods 609 are inserted into the slots 612.

[0034] A through-hole 608 is provided on the upper surface inside the sliding groove 611. A pressing rod 607 is slidably connected inside the through-hole 608, and the outer surface of the pressing rod 607 is in contact with the end of the mounting rod 609. A plurality of uniformly distributed through-channels 604 are provided inside the mounting plate 5. A pull rod 602 is slidably connected inside the through-channel 604, and the bottom end of the pull rod 602 is fixedly connected to the top end of the pressing rod 607. A first spring 603 is sleeved on the outer surface of the pull rod 602. Handle plates 601 are fixedly connected to the top ends of the front two pull rods 602 and the top ends of the rear two pull rods 602. During operation, the insertion plate 606 is stably inserted into the mounting groove 605 by inserting the mounting rod 609 into the insertion slot 612, and the mounting plate 5 is stably mounted on the top of the bottom plate 1. When it is necessary to disassemble the mounting plate 5 and the measuring assembly 9, first move the handle plate 601 so that the handle plate 601 drives the pull rod 602 to move. After the pull rod 602 moves, the first spring 603 is compressed so that the first spring 603 has a rebounding force. Then, the movement of the pull rod 602 drives the pressing rod 607 to move so that the pressing rod 607 is disengaged from the extrusion of the mounting rod 609. After the mounting rod 609 is released from the extrusion, the originally compressed second spring 610 has a rebounding force, and the rebounding force of the second spring 610 causes the mounting rod 609 to slide out of the insertion slot 612 and contract inside the sliding groove 611. In this way, the mounting rod 609 can be disengaged from the limit installation of the insertion plate 606, and then by moving the mounting plate 5, the insertion plate 606 can be removed from the mounting groove 605, so that the mounting plate 5 and the measuring assembly 9 can be disassembled and repaired. When reinstalling, first pull the handle plate 601 so that the handle plate 601 drives the extrusion to move, and the mounting rod 609 is received inside the sliding groove 611. Then, insert the insertion plate 606 into the mounting groove 605 to connect the mounting plate 5 and the bottom plate 1, and then release the handle plate 601 so that the pull rod 602 moves under the action of the rebounding force of the first spring 603 to drive the pressing rod 607 to move and extrude the mounting rod 609. Since the elastic coefficient of the first spring 603 is greater than that of the second spring 610, the pressing rod 607 can extrude the mounting rod 609 and the second spring 610, and the mounting rod 609 is inserted into the insertion slot 612 to limit the installation of the insertion plate 606, so that the insertion plate 606 is stably installed between the mounting plate 5 and the bottom plate 1.
