Description

Technical Field

[0001] The invention belongs to the technical field of underwater equipment, and in particular relates to a deep-sea large-capacity adjustable double-retractable local static sealing winch device. Background Art

[0003] The ocean vertical profile detector mainly consists of three parts: a float (sensor), a winch (cable reeling and releasing device) and a base (fixed positioning). The winches used in current detectors are mostly integrated into the float or base. Even with an integrated compact design, they are still oversized and overweight for the float. However, if it is integrated into the base, although there are no weight and size restrictions, the expensive and reusable winch almost becomes a disposable device. The detectors range from hundreds of meters to thousands of meters, and the winch integrated into the base needs to operate under high pressure all the time. As the failure rate increases, the salvage cost also increases accordingly.

[0004] At the same time, most underwater winches currently use a single-sided cable-retracting design. Due to the large torque required on the seabed, the device operates at a low speed. To increase the operating speed, it is necessary to replace it with a larger motor and use more energy. This will further increase the size of the underwater winch, and the regular cable arrangement of the cable reel will cause the device to shift when it is retracted and released.

[0005] Compared with the traditional integrated underwater winch design, the split underwater winch has great advantages. However, due to the split design, the winch is exposed in the ocean. As a special-shaped body in the cable, the winch will cause the fluid to exert force on the device, resulting in instability of the device.

[0006] Due to the weight and volume limitations of the underwater winch, the complexity of the dynamic seal structure, the device offset caused by the cable retracting and releasing, and other issues, the existing treatment methods can only solve some of the problems to a certain extent by continuously reducing the available space, using integral seals instead of split seals, and adopting guide wheel structures. Summary of the invention

[0007] The invention is based on the design of a split underwater winch and proposes a deep-sea large-capacity adjustable double-retractable local static sealing winch device.

[0008] The present invention proposes a deep-sea large-capacity adjustable double-retractable local static seal winch device, comprising a circular step winch, a floating baffle, a floating counterweight, a magnetic coupling coupling, a motor, a connecting bracket and a frame; wherein the circular step winch is a long cylinder with steps both inside and outside, the external steps are used to fix and limit the floating baffle, and the internal steps are used to fix and limit the magnetic coupling coupling, the motor and the electronic component assembly; the stator of the motor is fixed to the inside of the circular step winch by bolts, and the rotor of the motor is fixedly connected to the outer rotor of the magnetic coupling coupling; the inner rotor of the magnetic coupling coupling is connected to the transmission shaft by a shaft key, and the other end of the transmission shaft is fixed to the connecting bracket; the connecting bracket is connected to the frame; the floating baffle and the floating counterweight are installed on the outside of the circular step winch; a space for storing cables is formed between adjacent floating baffles; embedded end covers are provided at both ends of the circular step winch; the embedded end covers are connected to the connecting bracket through bearings.

[0009] Preferably, the floating baffle is a hollow circular ring plate, and the inner ring of the plate is provided with a step structure that matches the outer step of the circular step winch.

[0010] Preferably, a cable guide groove is reserved on the frame; a cable sleeve is installed in the cable guide groove.

[0011] Preferably, a deflector is provided on the outside of the circular stepped winch; the upper and lower ends of the deflector are respectively opened towards each other, and the openings are slightly larger than the tangent distance from the maximum radius of the retractable cable to the cable sleeve.

[0012] Preferably, reinforcing ribs are provided inside the air deflector.

[0013] Preferably, the maximum outer diameter of the frame is slightly smaller than the minimum aperture of the connecting bracket. Preferably, the maximum outer diameter of the embedded end cover is greater than the maximum outer diameter of the circular stepped capstan; and the embedded portion thereof is sealed by a double-layer O-ring.

[0014] Preferably, the embedded end cover is provided with a sensor opening and a cable opening.

[0015] The present invention solves the weight and volume restrictions of the winch device in the prior art through a split design. At the same time, the double retractable structure and the external cable guide frame are used to ensure the force centering of the underwater winch during the cable retracting and releasing process, and to ensure the stable operation of the device. Secondly, due to the use of magnetic coupling couplings, the internal waterproof parts are partially statically sealed, and the structure is simple and the waterproof and pressure-resistant effects are significant. Finally, the floating baffle adopts a quick-disassembly and quick-installation design, which is convenient for disassembly and assembly, and baffles of different diameters can be used for different cable capacities, and the compatibility is strong. The water-contacting materials of the device are mostly made of titanium alloy and POM (Saigang), which effectively avoids the problem of long-term underwater corrosion.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0018] The invention proposes a deep-sea large-capacity adjustable double-retractable local static seal winch device, the structure of which is Figure 1 and 2 As shown, it is mainly composed of a frame 2, a connecting bracket 5, a circular step winch 4, a floating baffle 10, a floating counterweight 3, a deflector 11, and an internal magnetic coupling coupling 7, a motor 8, and an electronic component assembly 9.

[0019] Among them, Figures 2 to 6 As shown, the circular step winch 4 is a long cylindrical structure made of POM material with steps inside and outside, wherein the internal steps are mainly used to fix and limit the magnetic coupling 7, the motor 8 and the electronic component assembly 9. The external steps are used to fix and limit the floating baffle 10.

[0020] The stator of the motor 8 is connected to the circular step winch 4 by bolts, so that the circular step winch 4 and the motor stator are completely fixed, and the rotor of the motor is inserted into the reserved step of the outer rotor 71 of the magnetic coupling coupling, and the outer rotor of the magnetic coupling coupling and the rotor of the motor are completely fixed by bolts.

[0021] The isolation cover 72 of the magnetic coupling coupling is fixed to the magnetic coupling end cover 42, wherein a reserved sealing ring groove is provided on the contact surface between the isolation cover 72 and the magnetic coupling end cover 42 for local static sealing to ensure the normal operation of the motor and internal electronic components.

[0022] The inner rotor 73 of the magnetic coupling coupling is inside the isolation cover 72 of the magnetic coupling coupling, wherein the inner rotor 73 is connected to the transmission shaft 74 via a shaft key.

[0023] The other end of the transmission shaft 74 is square and is inserted into the connecting bracket 5. In order to ensure correct positioning, a shaft stopper 6 is used to fix it.

[0024] After the electronic component assembly 9 is connected to the motor 8, it is limited by a circular stepped winch. The numerous electronic components 92 are fixed using an electronic component box 91 to ensure that the electronic components are stationary during operation. Secondly, the sensor is connected to the outside world through the sensor opening 47 on the motor end cover 45.

[0025] The cables required by the electronic component assembly 9 are connected to the outside through the cable opening 44 on the motor end cover 45 to ensure the power supply system and information transmission system of the winch.

[0026] The magnetic coupling end cover 42 and the motor end cover 45 are respectively installed with the connecting bracket 5 through the first bearing 43 and the second bearing 46, so as to ensure that the cylinder composed of the circular step winch 4 and the two end covers can stably rotate on the connecting bracket 5. The magnetic coupling end cover, the motor end cover and the circular step winch are designed to be embedded, and the embedded part is sealed by a double-layer O-ring.

[0027] The connecting bracket 5 is fixed to the frame 2 by bolts. In order to ensure smooth retraction and extension of the cable, a cable sleeve 1 is installed on the frame 2 to guide the cable up and down to the center position.

[0028] The floating baffle 10 and the floating counterweight 3 are installed on the circular step winch, which can accommodate the cable and counterweight the buoyancy and center of gravity of the winch. In the present invention, there are three floating baffles 10, the outer side of the floating baffle 10 is regularly hollowed out to form a hollow structure, and the inner ring is provided with a stepped structure that matches the outer step of the circular step winch 4. Because the pressure on both sides of the cable of the outer ring is reduced and it is also for the lightness of the device. The upper cable channel 48 and the lower cable channel 49 are reserved on the floating counterweight 3.

[0029] The function of the flow guide cover 11 is to reduce the effect of the fluid on the device by diverting the flow, and the upper and lower ends are respectively opened, and the openings are slightly larger than the tangent connection from the maximum radius of the cable to the cable sleeve 1 to ensure smooth cable retraction and release. The interior of the flow guide cover 11 is reinforced with reinforcing ribs to ensure its integrity under long-term seawater impact.

[0030] After the two cables are connected through the cable opening 44, they are connected to the cable grooves of the cables through the upper cable channel 48 and the lower cable channel 49. In order to ensure the sealing of the cable opening, a watertight joint is used to connect it to the internal cabin.

[0031] The winch device of the present invention retracts and releases the cable by passing two cables through the cable guide grooves reserved in the upper and lower frames 2, and then installing the cable sleeve 1. The cable sleeve 1 is made of polytetrafluoroethylene material, and the lower end is fixed by a retaining ring to prevent the cable from being brought out during the retraction and release process. After that, the cables are respectively wound close to the middle baffle plate, and after winding one or two layers, they are led to the motor end cover 45 through the upper cable channel 48 and the lower cable channel 49 reserved by the circular ladder winch 4, the floating baffle plate 10 and the floating counterweight block 3 to connect to the watertight joint fixed on the motor end cover, completing the cable operation of the underwater winch.

[0032] Push the middle floating baffle directly into the higher step through the lower step side, then use nuts to fix the floating baffle and the circular step winch, and then push the floating baffles on both sides into the steps on both sides from both ends respectively. Finally, push the floating counterweight block directly into the circular step winch, squeezing the floating baffles on both sides. At this time, the external parts of the circular step winch have been installed.

[0033] Install the motor 8 through the side with the larger stepped hole, such as Figure 2 Then use nuts to fix the circular ladder winch to the motor, and then follow the steps below. Figure 2 The outer rotor of the magnetic coupling is installed on the right end of the motor. After the outer rotor is aligned with the motor, the countersunk bolts are installed inside the inner rotor to completely fix it to the rotor of the motor. Then install the electronic component 92 into the electronic component box 91, as shown in the following figure. Figure 2 Push it into the circular step winch from the left end to complete the installation of the internal parts of the circular step winch.

[0034] Install the motor end cover 45 with two O-rings for sealing. Figure 2 The left side of the circular step winch is fixed to the circular step winch with bolts. Since the maximum outer diameter of the end cover is larger than the circular step winch, the left floating counterweight installed in the previous step can be clamped, thereby ensuring that the floating body on the left side of the winch is completely fixed.

[0035] After fixing the inner rotor 73 of the magnetic coupling coupling to the transmission shaft 74 through the shaft key, install the bolts to fix the transmission shaft and the inner rotor to ensure the connection and fixation, then insert the transmission shaft into the magnetic coupling end cover 42, and then install the isolation cover sealing ring of the magnetic coupling coupling 7, put it on the inner rotor that has been inserted into the end cover, and then fix the isolation cover to the magnetic coupling end cover through bolts. After installing the installed right end cover into the installed outer rotor, fix it to the circular ladder capstan through bolts in the same way as the left side.

[0036] At this point the winch drum and cable have been installed, then install the bearings of the two end covers. Figure 2 The right side needs to be fixed with a retaining ring, and then the connecting brackets 5 are pushed onto both sides, and then the shaft stops on both sides are installed to limit the position. Finally, the frame 2 is aligned with the reserved holes in the connecting bracket 5 to complete the installation of the main structure of the underwater winch. Finally, the deflector 11 is covered on the outside of the winch cylinder device, and then the reserved circular holes on the contact surfaces of the two deflectors are positioned with bolts and nuts.

[0037] The present invention discloses a deep-sea large-capacity adjustable double-retractable local static sealing winch device, wherein a frame 2 is used for a single centering cable groove and an overall centering device for retracting and releasing cables, so that the cables can be placed relatively neatly in the cable groove, and the centering stability of the device can be ensured during the cable retraction and release process. Secondly, the frame is made of titanium alloy material to ensure that the device structure will not fail due to corrosion during long-term use in the deep sea. The tail end of the frame is installed in a deep hole reserved in a connecting bracket 5, wherein the maximum outer diameter of the frame is slightly smaller than the minimum aperture of the connecting bracket, so that a gap is left during installation so that the frame tube can be filled with seawater, the pressure on the frame is reduced, and the service life is increased. The frame is fixed to the connecting bracket by bolts and nuts, wherein the middle points of the four sides of the connecting bracket are respectively provided with hanging The ears facilitate the transportation and lifting of the device. At the same time, the connecting bracket also serves as a limiting device for the capstan cylinder. Since the distance between the frame and the connecting bracket is fixed, the distance between the connecting brackets is also fixed. The position of the middle capstan cylinder is limited by the shaft stops 6 on both sides. At the same time, in order to ensure the normal rotation of the circular step winch, the first bearing 43 and the second bearing 46 are respectively installed on the connecting bracket 5 to ensure that they can still operate normally under strong radial force. At the same time, the bearings are fixed with retaining rings to ensure that the cylindrical roller bearings operate within the designed range. Finally, the two ends of the circular step winch 4 are evenly connected and fixed to the magnetic coupling end cover 42 and the motor end cover 45 through countersunk nuts, and the two end covers respectively have two O-ring grooves for sealing.

[0038] The embedded connection contact surfaces between the circular step winch 4 and the two end covers adopt transition fit to ensure the safety of the high-pressure static sealing of the device. Secondly, the maximum outer diameter of the end cover is larger than the maximum outer diameter of the circular step winch, ensuring that the middle floating structure can be clamped by the end cover.

[0039] The floating baffle 10 and the floating counterweight 3, only the middle floating baffle needs to be installed from one end of a specific small step, such as Figure 1 The left side of the float baffle and the float counterweight on both sides can be installed from both ends of the winch in the order of placing the float baffle first and then the attached counterweight. After the device is fully installed and can be debugged normally, the two halves of the deflector 11 can be directly covered on the float capstan, and then positioned and fixed through the round holes on the contact surface of the two deflectors.

[0040] The internal structure includes a magnetic coupling 7, a motor 8, and an electronic component 9. First, install the motor and fix it on the circular step winch, then install the outer rotor 71 of the magnetic coupling coupling on the rotor of the motor. Then, connect the inner rotor and the transmission shaft and put it into the hole of the magnetic coupling end cover. Then, cover the isolation cover of the magnetic coupling coupling on the inner rotor and fix it to the magnetic coupling end cover, and then install it on the installed outer rotor. Finally, assemble the electronic components and the electronic component box, connect the electronic components to the motor, and push them into the circular step winch. Then, install the sealing end of the watertight joint on the motor end cover, connect it to the electronic components, and then install the motor end cover to complete the installation of the winch.

[0041] In this embodiment, the clockwise rotation or counterclockwise rotation of the motor can drive the rotation of the winch, because the rotor of the motor is fixed to the bracket through a magnetic coupling coupling, so the rotor of the motor is fixed, and the stator of the motor is connected to the circular step winch, and the two ends of the circular step winch are fixed with bearings so that the circular step winch can rotate at will, so the stator of the motor will drive the winch to rotate to complete the task of retracting and releasing the cable.
