Description

Technical Field

[0001] The present invention relates to the technical field of marine penetration equipment, and in particular to a probe rod recovery device of a winding static penetration equipment. Background Art

[0002] Existing winding-type static penetration probe equipment primarily consists of a roller assembly for probe insertion and retrieval, a probe straightening device, and other measurement, control, and auxiliary devices. The probe is bent and wound between the inner and outer rollers of the roller assembly, with the outer roller being fixed. A motor drives the inner roller in forward and reverse rotation, while the roller assembly's planetary gear mechanism drives three screw-nut pairs to achieve axial and reverse motion of the inner roller, thus completing the probe insertion and retrieval motion.

[0003] However, there are deficiencies in the prior art:

[0004] 1. The probe rod is prone to fatigue damage due to repeated bending and straightening. It is a consumable part that needs to be replaced frequently. After the probe rod is bent, it is clamped between the inner and outer rollers. Due to the rebound force, there is a lot of pressure between it and the outer roller, making it very difficult to disassemble and replace.

[0005] 2. When the probe penetrates the seabed, the combined effects of the aforementioned rebound force and the penetration reaction force create a significant pressure between the probe and the fixed outer drum. As the probe slides circumferentially along the outer drum to extend and penetrate, significant friction exists between the two. As penetration depth increases, the penetration reaction force increases, further increasing the friction between the two. This friction severely restricts penetration depth.

[0006] 3. The planetary gear mechanism that achieves the axial reciprocating motion of the inner drum requires high machining and installation precision. Furthermore, the planetary gear mechanism must coordinate with three sets of screw nut pairs and three sets of guide pins and sleeves, further increasing the difficulty of machining and installation.

[0007] Therefore, there is an urgent need for a probe rod recovery device for a winding-type static penetration probe equipment to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-Figure 5 As shown, this embodiment provides a probe rod recovery device for a winding static penetration equipment, including a frame 18, on which a probe rod recovery mechanism 20 is installed, and the probe rod recovery mechanism 20 includes a reduction motor 11, and the output shaft of the reduction motor 11 is transmission-connected to the second flange 10, and the second flange 10 is detachably connected to the first flange 9, and the center of the first flange 9 is rotatably connected to the center shaft 5, and the side wall of the first flange 9 is fixedly connected to the second side plate 8, and the side of the second side plate 8 away from the first flange 9 is provided with a first side plate 6, and a roller 4 is installed between the first side plate 6 and the second side plate 8, and the roller 4 is threadedly connected to the center shaft 5, and a probe rod 3 is wound around the outside of the roller 4.

[0030] One end of the probe rod 3 is fixed to the drum 4, and the other end is equipped with a probe, which is used to insert into the seabed to collect data. When recovering the probe rod, the reduction motor 11 at the probe rod recovery mechanism 20 works and transmits power to the reduction motor 11 output shaft. The output shaft transmits power to the second flange 10, and the second flange 10 is connected to the first flange 9, and the first flange 9 is connected to the second side plate 8, thereby transmitting power to the second side plate 8. The second side plate 8 drives the drum 4 and the first side plate 6 to rotate. Since the hub of the drum 4 and the central shaft 5 are matched at the place where the pitch is the diameter of the probe rod 3, the drum 4 can move axially by the distance of the probe rod 3 every time it rotates one circle, ensuring fixed-point penetration and recovery. The present invention does not have an outer drum 4, which avoids friction between the probe rod 3 and it, reduces wear, makes penetration and recovery more convenient, and simplifies the overall structure, which is convenient for installation and disassembly. The central shaft 5 is a fixed structure that only bears bending moment but does not transmit torque, thereby ensuring the bearing capacity and strength of the central shaft 5 and improving the service life of the central shaft 5.

[0031] In a further optimized solution, a one-way bearing 12 is sleeved on the outer side of the output shaft of the reduction motor 11. A first B-type flat key 13 is installed on the inner ring of the one-way bearing 12, which is clamped to the output shaft of the reduction motor 11. A second B-type flat key 15 is installed on the outer ring of the one-way bearing 12, which is clamped to the inner side of the second flange 10. The output shaft of the reduction motor 11 drives the inner ring of the one-way bearing 12 to rotate through the first B-type flat key 13. In this direction, the inner and outer rings of the one-way bearing 12 are locked (i.e., synchronous rotation is achieved). Therefore, power can be transmitted to the second flange 10 through the one-way bearing 12 and the second B-type flat key 15. The second flange 10 is connected to the first flange 9, thereby driving the drum 4 to rotate.

[0032] Further optimizing the solution, a compensation washer 14 is attached to one side of the one-way bearing 12, and the compensation washer 14 is sleeved on the outer side of the output shaft of the reduction motor 11. The compensation washer 14 limits the one-way bearing 12 to ensure good transmission performance.

[0033] A further optimization scheme is to provide a threaded section on the central shaft 5, and a screw nut 17 is fixedly connected to the inner ring of the drum 4, which is threadedly connected to the threaded section. The threaded portion at the hub of the drum 4 is formed into a screw nut 17, which is threadedly connected to the threaded section, facilitating the movement of the drum 4. At the same time, the screw nut 17 is made of the relatively wear-resistant material aluminum bronze, which improves wear resistance and is also easy to replace.

[0034] In a further optimization scheme, a plurality of guide posts 7 are fixedly connected between the first side plate 6 and the second side plate 8, and a plurality of guide sleeves are fixedly connected to the roller 4. The guide posts 7 are arranged in a one-to-one correspondence with the guide sleeves, and the guide posts 7 extend through the guide sleeves. The guide posts 7 are located between the first side plate 6 and the second side plate 8, serving as a connection to facilitate force transmission. The guide sleeves cooperate with the guide posts 7. When the first side plate 6 and the second side plate 8 rotate, the roller 4 rotates, completing the recovery of the probe rod 3.

[0035] Further optimizing the scheme, the outer rings of the first flange 9 and the second flange 10 are respectively equipped with bearing bushes 16. The bearing bushes 16 are made of wear-resistant materials such as bronze and anti-friction alloy, and an oil film is provided between the first flange 9 and the second flange 10 to play a lubricating role.

[0036] A further optimized solution is that friction wheels 1 are symmetrically provided at the penetration end of the probe rod 3. The probe rod 3 passes between the two friction wheels 1 and is slidably connected to the friction wheels 1. The friction wheels 1 are driven by an external motor. The friction wheels 1 are provided for the penetration of the probe rod 3. This application has both the penetration and recovery functions of the probe rod 3, and is highly practical.

[0037] To further optimize the solution, a straightener 2 is provided above the friction wheel 1 , and the straightener 2 is used to straighten the probe rod 3 .

[0038] In a further optimized solution, a bearing support bracket 19 is fixed to the frame 18, and the end of the central shaft 5 passes through the top of the bearing support bracket 19 and is fixed to the bearing support bracket 19. The central shaft 5 is fixed to the top of the bearing support bracket 19, so that the central shaft 5 only bears bending moment but does not transmit torque, and has higher strength.

[0039] To further optimize the solution, a reduction motor bracket 21 is fixedly connected to the side of the frame 18 away from the bearing seat bracket 19. The reduction motor 11 passes through the top of the reduction motor bracket 21 and is fixed to the reduction motor bracket 21. The reduction motor bracket 21 supports the reduction motor 11 and ensures the stability of the structure.

[0040] Working principle:

[0041] When the probe 3 retracts, the reduction motor 11 drives the second flange 10 via the one-way bearing 12. The second flange 10 is then bolted to the first flange 9, driving its rotation. Both flanges 9 and 10 are supported by sliding bearings and the frame 18. The first flange 9 is bolted to the second side plate 8, driving its rotation. The second and first side plates 8 are fixedly connected to each other via six guide posts 7. The first and second side plates 6, 8, are supported on the central shaft 5 via sliding bearings. The first and second side plates 6, 8, rotate together around the central shaft 5. One end of the central shaft 5 is connected to and supported by the second side plate 8, while the other end is fixedly connected to the bearing support 19. The roller 4 has six guide sleeves that mate with the guide posts 7, driving its rotation. The roller 4, driven by the guide posts 7, rotates by engaging the rectangular threaded sections on the central shaft 5. Each rotation of the roller 4 corresponds to one thread pitch, where the thread pitch is equal to the diameter of the probe 3. As the drum 4 rotates, the probe rod 3 on the drum 4 is recovered - bent and wound side by side on the drum 4. When the probe rod 3 performs the recovery movement, the two friction wheels 1 are moved away from each other through the external sliding component, thereby disengaging the probe rod 3 from the friction wheel 1 and completing the recovery movement.

[0042] As the probe 3 penetrates, the friction wheel 1 below pulls it downward, and the straightener 2 straightens the bent probe 3. At this point, the drum 4 passively rotates and moves axially, enabling continuous penetration of the probe 3. Due to the action of the one-way bearing 12, the second flange 10, which rotates with the drum 4, only drives the inner ring of the one-way bearing 12; the outer ring of the one-way bearing 12, which is connected to the reduction motor 11, does not rotate. Therefore, the recovery motion is automatically decoupled from the reduction motor 11 motion.

Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
