Detailed implementation manners

[0027] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0028] An automatic dropping device for a gantry type static cone penetration testing equipment, as Figure 1-8 shown, includes a static cone penetration testing equipment 1. The static cone penetration testing equipment 1 automatically falls to the seabed. A probe is provided at its bottom. After falling on the seabed, it inserts into the seabed for data collection and transmits the data back through satellite connection.

[0029] During the dropping process, a hull system and a dropping system 2 are used. The dropping system 2 is arranged on the hull system. The hull system is controlled to travel to a predetermined sea area; the dropping system 2 is connected to the static cone penetration testing equipment 1 and controls it to be dropped from the hull system to a predetermined position;

[0030] Specifically, the hull system is an unmanned boat, which includes a boat body 7, a control box 5, a generator 6, a main engine 8, and a jet pump 9. As Figure 1 、 5 shown, the unmanned boat is composed of a boat body 7, a control box 5, a generator 6, a fuel tank 29, a main engine 8, etc.; it can be remotely controlled or automatically controlled to move to a predetermined sea area according to the navigation;

[0031] Specifically, the overall composition of the gantry scheme is as Figure 1 、 2 shown. The entire gantry type autonomous dropping device mainly consists of an unmanned boat, a winch 4, a locking mechanism 19, a hanging frame mechanism 3, and a hook releasing mechanism. The base of the winch 4 is fixed on the deck in the middle section of the unmanned boat, so that the hanging frame mechanism 3 is configured to be movably arranged on one side of the hull and is controlled to rotate out of the hull to form a frame for dropping the static cone penetration testing equipment 1 outside the hull; as Figures 4-6 shows the process of the hanging frame mechanism 3 rotating from the inside of the hull to the outside.

[0032] And the hanging frame mechanism 3 and the locking mechanism 19 are fixed on the deck at the tail of the unmanned boat, and the hook releasing mechanism is fixedly connected to the end of the rope 18. The winch 4 is connected to the static cone penetration testing equipment 1 through the hanging frame mechanism 3 to form the dropping control for it. Specifically, the end of the rope 18 is connected to the static cone penetration testing equipment 1 through an automatic hook releasing mechanism 28; as Figure 3As shown in the figure, the decoupling mechanism includes a suspension plate. A plurality of hooks are hinged around the suspension plate. A suspension ring for connecting the rope 18 is provided in the middle of the suspension plate. The hooks are hinged and distributed around the suspension plate. When the hooks are not subject to external forces, the hook openings face downward due to their own gravity and are in a balanced state. When the hooks are in a loaded state, they can maintain the state where the hook openings face upward. When the static cone penetration device reaches the underwater detection point, the hooks are not loaded. The rope 18 continues to extend. To balance its own weight, the hook openings gradually turn outward. During this period, the suspension ring slides out of the hooks, thus realizing the automatic decoupling process.

[0033] Furthermore, the hanger mechanism 3 includes a base 10, a gantry 11, and a first hydraulic cylinder 12. The hanger is arranged at the tail of the hull. Bases 10 are respectively arranged on both sides of the tail of the hull. The gantry 11 is hinged on the two bases 10. The feet 14 of the two side struts 13 of the gantry 11 are respectively hinged to one end of the base 10. The other end of the base 10 is hinged with the first hydraulic cylinder 12. The other end of the first hydraulic cylinder 12 is hinged to the middle of the strut 13. The first hydraulic cylinder 12 controls the upper part of the gantry 11 to rotate out of the hull. To meet the requirements of supporting the static cone penetration equipment 1, a pair of hydraulic cylinders are used to realize the rotation of the gantry 11. As Figure 2 shown, it is the structure diagram of the hanger mechanism 3.

[0034] The hanger mechanism 3 drives the gantry to rotate around the joint of the foot 14 of the strut 13 by controlling the rod of the first hydraulic cylinder 12 to extend, so as to complete the conversion of the position of the static cone penetration device. The pulley serves as the lifting fulcrum of the rope 18. The pulley is rotatably arranged on the rotating bracket 16. The tension sensor is used to detect the tension received by the fulcrum and is used to judge whether the static cone penetration device reaches the bottom of the water. Furthermore, a rotating bracket 16 is provided in the middle of the top cross beam 15 of the gantry 11. The upper end of the rotating bracket 16 is hinged to the ear seat 17 arranged in the cross beam 15, so that the lower end of the rotating bracket 16 swings along with the movement of the static cone penetration equipment 1 and the gantry 11. As Figure 3 shown, in actual use, a tension sensor can be set on the rotating bracket 16. To ensure the accuracy of the measurement of the tension sensor, the sensor is installed at the upper end of the pulley bracket. To ensure the stability of its measurement, a rotating bracket 16 is designed on the other side, so that the measured tension direction is always the vertical direction. By detecting the tension acting on it by the rope 18, it can be reflected whether the static cone penetration equipment 1 has sunk to the bottom. After sinking to the bottom, the automatic decoupling mechanism 28 disconnects the static cone penetration equipment 1 from the rope 18, and then controls the winch 4 to reel in according to the tension signal.

[0035] Further, the hanger mechanism 3 further includes a locking mechanism 19. The locking mechanism 19 selects a hydraulic cylinder as an actuator, and the extension of the hydraulic cylinder is used to push the locking block 22 to continuously apply a certain contact pressure to the static cone penetration equipment 1. Since the installation space in the width direction of the unmanned boat is limited, the hydraulic cylinder is placed along the longitudinal axis of the boat body, and the longitudinal force is converted into a lateral clamping force through a connecting rod transmission mechanism. The structure of the locking mechanism 19 is as shown in Figure 7 , 8 . The locking mechanism 19 is arranged on the deck of the boat body, and the locking mechanisms 19 are respectively arranged on both sides of the placement position of the static cone penetration equipment 1 to form clamping and fixing of the static cone penetration equipment 1.

[0036] Specifically, the locking mechanism 19 includes a bottom plate 20, a second hydraulic cylinder 21, a locking block 22, and a connecting rod structure 23. An accommodation chamber 24 is formed inside the bottom plate 20. An outlet 25 for the telescopic movement of the locking block 22 is provided on one side of the accommodation chamber 24. The second hydraulic cylinder 21 and the connecting rod structure 23 are arranged in the accommodation chamber. The second hydraulic cylinder 21 is arranged at one end of the accommodation chamber 24 far from the outlet 25. The connecting rod structure 23 includes a first connecting rod 26 and a second connecting rod 27. One end of the first connecting rod 26 is hinged to the locking block 22, and the other end is hinged to the hydraulic rod end of the second hydraulic rod. One end of the second connecting rod 27 is hinged in the middle of the first connecting rod 26, and the other end is hinged at one end of the accommodation chamber 24 far from the second hydraulic cylinder. One end of the cylinder body of the second hydraulic cylinder 21 is hinged and arranged in the accommodation chamber 24. Figure 7 As shown in the figure, it is the state where the locking block 22 of the locking mechanism 19 on one side contracts, Figure 8 and it is the state where the locking block 22 extends.

[0037] This launching device adopts the gantry crane method. Before launching, the static cone penetration equipment 1 is placed under the hanger on the rear deck of the unmanned boat and fixed in position by the locking mechanism 19. The rope 18 of the winch 4 on the boat is connected to the static cone penetration equipment 1 through the pulley above the hanger. The end of the rope 18 is connected to the unhooking mechanism, and a tension sensor is installed above the pulley. The overall structure layout is as shown in Figure 1 , 2 , and Figure 4.

[0038] The launching process is as shown in Figures 4-6 . In this scheme, locking mechanisms 19 are installed on both sides of the static cone penetration equipment 1 to maintain its stability on the boat before launching. The locking mechanism 19 realizes the locking function by pushing the locking block 22 through a hydraulic cylinder, as shown in Figure 7 . Before launching, the hydraulic cylinders of the locking mechanisms 19 on both sides of the static cone penetration equipment 1 need to be retracted first, and the locking blocks 22 start to move away from the equipment, thus releasing the locked state of the equipment, as shown in Figure 8 .

[0039] Start launching, as shown inFigure 4 As shown, first start the winch 4. The winch 4 retracts part of the rope 18, and at the same time disengages the static cone penetration equipment 1 from the deck and hoists it to a certain height to ensure that it does not collide with the hull 7 during the dropping process.

[0040] Secondly, the first hydraulic cylinders 12 on both sides of the hanger mechanism 3 are synchronously advanced to make the hanger swing backward around the fulcrum of the base 10. At the same time, the winch 4 steadily pays out the rope as the hanger rotates, ensuring that the relative position between the static cone penetration equipment 1 and the pulley remains unchanged. The collaborative working process is as Figure 5 shown. When the first hydraulic cylinder 12 is pushed to the farthest end, the static cone penetration equipment 1 reaches above the dropping water area, completing the position transformation between the deck and the dropping point, as Figure 6 shown.

[0041] Then, the winch 4 continues to lower the rope 18. When the value of the tension sensor on the hanger returns to zero, it is confirmed that the static cone penetration equipment 1 reaches the underwater detection area.

[0042] Finally, the winch 4 continues to lower the rope 18 by 1 m. Due to the lack of the action of the equipment gravity, the ring on the hook release mechanism pushes upward out of the hook opening during this process, realizing the automatic hook release action. Thus, the dropping of the static cone penetration equipment 1 is completed.

[0043] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
