Abstract
Description
Technical Field
[0001] This invention relates to the field of underwater towing winch impeller technology, and more specifically, to a cylindrical support type towing winch impeller. Background Technology
[0002] In the current field of underwater exploration, unmanned underwater deployment and retrieval systems generally consist of a towed body, tow cable, deployment and retrieval device, and winch. Whether using an underwater vehicle for autonomous exploration or a towed body for towed exploration, this system is essential for the smooth deployment of instruments and equipment connected to the tow cable from the mother ship platform into the water. After the equipment completes its designated task through towing at a fixed depth, it must be safely and smoothly retrieved back to the deck. Therefore, the deployment and retrieval system is a crucial link between the mother ship platform and the underwater medium. The winch in the deployment and retrieval system directly acts on the tow cable, handling the cable's retrieval, deployment, and towing while also bearing the enormous tension generated by the cable. The quality of the winch is critical to the system's successful mission execution. However, currently, using a single underwater winch is often constrained by factors such as size, weight, and towing force, so it is usually designed as a cable storage winch and a towing winch. The cable storage winch is responsible for storing the tow cable and only needs to withstand a certain range of low tension, so the required structural strength is not high. The towing winch, on the other hand, is responsible for bearing the majority of the tension generated by the tow cable, requiring not only high structural strength but also a lightweight design that cannot contribute too much to the overall weight of the winch. For the non-watertight drive motor, sealing treatment is also required, which presents a significant design challenge. Summary of the Invention

Therefore, the objective of this invention is to propose a cylindrical support type towing winch impeller that achieves a lightweight and miniaturized design while meeting requirements for volume, weight, and sealing.
[0004] To achieve the above and other related objectives, the present invention provides a cylinder-supported towing winch impeller, comprising: A sealing cylinder has a front sealing cover installed at its front end and a rear sealing cover installed at its rear end.

A detachable wheel groove is fixedly installed on the outer periphery of the wheel spokes. The detachable wheel groove is used to wind the towing cable and transmit towing tension.
[0006] In one embodiment of the present invention, it further includes: The mounting bracket is fixedly connected to the mounting flange on one side of the sealing cylinder; The mounting plate is fixedly connected to the mounting bracket; The small bushing is fitted into the mounting plate on its outer side.

Secondly, the flange at the rear of the cylinder is securely fastened to the towing winch mounting frame, ensuring the cylinder remains stationary. Finally, the supporting flange in the middle of the cylinder provides support for the bushing and spokes, eliminating potential strength issues associated with the cantilever structure. Therefore, it possesses good overall integrity and strength, significantly improving the structural compactness.
[0015] The present invention discloses a cylindrical support type towing winch impeller, which simultaneously satisfies the functions of motor installation and sealing, sealing cylinder installation and fixing, and shaft sleeve and impeller support. This makes the overall structure of the towing winch more compact. Under the conditions of meeting volume, weight and sealing requirements, it achieves lightweight and miniaturized design, and provides a sealing environment and installation and fixing bracket for motors without watertight structures.

[0033] Please see Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of a single wheel structure of a cylindrical support type towing winch according to an embodiment of the present invention; Figure 2 This is a schematic diagram of a cylindrical support type towing winch impeller according to an embodiment of the present invention. The present invention provides a cylindrical support type towing winch impeller, comprising: a front sealing cover 6 sealed at the front end of a sealing cylinder 2, and a rear sealing cover 1 sealed at the rear end of the sealing cylinder 2; the sealing cylinder 2, the front sealing cover 6, and the rear sealing cover 1 together constitute a sealing cylinder body; the front end of a motor 3 is fixed to the front sealing cover 6, the output cable of the motor 3 is connected to the rear sealing cover 1, the output shaft of the motor 3 is connected to a rotating shaft 13, and a dynamic seal is formed between the rotating shaft 13 and the front sealing cover 6; the sealing cylinder body provides a watertight environment for the motor 3.
[0034] The present invention provides a cylindrical support type towing winch impeller that simultaneously satisfies the functions of motor installation and sealing, sealing cylinder installation and fixing, and shaft sleeve and impeller support, making the overall structure of the towing winch more compact and achieving lightweight and miniaturized design while meeting the requirements of volume, weight and sealing.
[0035] Specifically, the cylindrical support type towing winch impeller of the present invention further includes: a support flange installed in the middle of the outer wall of the sealing cylinder 2; the support flange is fixedly connected to the spokes 7 through a large bushing 4, so that the spokes 7 changes from a cantilever structure to a double-supported simply supported beam; a detachable wheel groove 5 is fixedly installed on the outer periphery of the spokes 7, and the detachable wheel groove 5 is used to wind the towing cable and transmit the towing tension.
[0036] Specifically, the cylindrical support type towing winch impeller of the present invention further includes: a mounting frame 8 fixedly connected to a mounting flange on one side of the sealing cylinder 2; a mounting plate 9 fixedly connected to the mounting frame 8; and a small bushing 10 sleeved into the mounting plate 9.
[0037] Specifically, the cylinder-supported towing winch impeller of the present invention further includes: an encoder 11 fixed to the sealing cylinder 2 and located inside the rear sealing cover 1; an encoder shaft 12 connected to the encoder 11; and the encoder shaft 12 and the shaft 13 coaxially connected.
[0038] In one embodiment of the present invention, a cylindrical support type towing winch impeller of the present invention is connected as follows: the rear sealing cover 1, the sealing cylinder 2, and the front sealing cover 6 are connected and fastened together by screws, nuts, and sealing rings to form a sealing cylinder. The motor 3 is fixed to the front sealing cover 6 by screws, and the output end is connected to the rotating shaft 13 by a flat key. The support flange on the sealing cylinder 2 is sequentially fitted with a large bushing 4, a spoke 7, a detachable wheel groove 5, and the rotating shaft 13. The detachable wheel groove 5 and the spoke 7, and the spoke 7 and the rotating shaft 13 are both connected and fastened together by screws. After the rotating shaft 13 is sequentially fitted with a small bushing 10 and adjusting washers of different thicknesses, the rear end ( Figure 1 The left side of the middle section is installed in conjunction with the front sealing cover 6, and the front end ( Figure 1 The right side of the sealing cylinder 2 is installed in conjunction with the mounting plate 9. Finally, the rear mounting flange of the sealing cylinder 2 is connected and secured to the mounting bracket 8 at the rear end of the cylinder body with screws, and the mounting plate 9 is connected and secured to the mounting bracket 8 at the front end of the cylinder body with screws. In addition, the test equipment required for the system, such as the encoder 11 and encoder shaft 12, can be installed inside the towing winch shaft 13.
[0039] Figure 1This diagram illustrates a cylinder-supported towing winch impeller structure, primarily composed of a rear sealing cover 1, a sealing cylinder 2, a motor 3, a large shaft sleeve 4, a detachable wheel groove 5, a front sealing cover 6, wheel spokes 7, a mounting bracket 8, a mounting plate 9, a small shaft sleeve 10, an encoder 11, an encoder shaft 12, and a shaft 13. The motor 3 is fixed to the front sealing cover 6 via a front mounting flange using screws. The front sealing cover 6 is then secured to the sealing cylinder 2, and the sealing cylinder 2 is subsequently secured to the mounting bracket 8 using screws and nuts. Therefore, when the motor 3 rotates, the main body remains stationary, while only the output shaft rotates. At the output end, the motor 3's output shaft is connected to the shaft 13 via a key. The shaft 13 is connected to the wheel spokes 7, and the wheel spokes 7 are connected to the detachable wheel groove 5. Therefore, when the output shaft rotates, it will drive the detachable wheel groove 5 on the wheel spoke 7 to rotate. Thus, during the winding and unwinding operation, the friction between the tow cable and the detachable wheel groove 5 can offset most of the towing force, thereby bearing most of the tow cable tension. This reduces the tension of the tow cable entering and leaving the cable storage winch and causes it to fluctuate within a small range, effectively protecting the operational safety of the cable storage winch and the entire subsystem.
[0040] To ensure underwater sealing and installation of motors without watertightness, the method employed in this invention is as follows: Figure 1 In the shown configuration, motor 3 is secured to the front sealing cover 6 via screws through the front mounting flange. The output cable of motor 3 is connected to the rear sealing cover 1 via a watertight connector. The output shaft of motor 3 is connected to the rotating shaft 13 via a key, and the rotating shaft 13 forms a dynamic seal with the front sealing cover 6. Therefore, the sealing cylinder, composed of the rear sealing cover 1, the sealing cylinder 2, and the front sealing cover 6, provides a watertight environment for motor 3. Furthermore, the fixation of motor 3 is transformed into the fixation of the sealing cylinder. This design simultaneously achieves underwater sealing and installation fixation of the motor, and is worthy of reference.
[0041] To ensure the strength of the impeller during operation, the method adopted in this invention is as follows: Figure 1 In the shown state, a support flange is added by integral welding in the middle of the sealing cylinder 2. The large bushing 4 and the spokes 7 are then installed sequentially on the support flange using interference fits and clearance fits. Therefore, the originally cantilevered spokes 7 are transformed into a simply supported beam structure with two supports by adding a fulcrum. This not only significantly improves the structural strength of the wheel but also reduces the wall thickness of the spokes 7 and eliminates the original support ribs, greatly reducing the weight of the entire component.
[0042] To ensure the integrity and ease of installation of the towing winch sheave structure, the method adopted in this invention is as follows: Figure 1In the shown state, after the motor 3 is installed, a drying box, a water leakage alarm, and heat sinks can be added inside the sealing cylinder 2 by adding a mounting bracket. After the above equipment is installed, the rear sealing cover 1 is closed, making it, the sealing cylinder 2, and the front sealing cover 6 form a sealed whole. For the rotating part, the rotating shaft 13 is installed with the small bushing 10, adjusting shims, and spokes 7, and then integrally installed with the sealing cylinder. The spokes 7 connect to the large bushing 4 on the outside, and the rotating shaft 13 connects to the motor key on the inside, thus forming a rotating wheel assembly. Finally, this rotating wheel assembly is removed from... Figure 1 As shown, the left side passes through to the right, and the mounting flange on the left sealing cylinder 2 is fastened to the mounting bracket 8 with screws. On the right side, the outer small bushing 10 is inserted into the mounting plate 9, and the mounting plate 9 is fastened to the mounting bracket 8 with screws, thus completing the overall installation of the impeller and the working frame. Finally, external parts and equipment such as the detachable wheel groove 5, encoder shaft 12, and encoder 11 are added, thereby completing the installation of the entire single impeller of the towing winch.
[0043] In one embodiment of the present invention, the working principle of a cylindrical support type towing winch impeller is as follows: The towing winch consists of two impellers with similar structures. The towing cable is wound several times around the impeller groove. When the towing cable is subjected to towing tension, it embeds itself in the impeller groove. The friction generated by the friction between the towing cable and the impeller groove can offset most of the tension, providing a small and relatively constant tension for the cable storage winch. Based on the above principle, this cylindrical support type towing winch impeller also needs to overcome the sealing problems caused by the underwater working environment, as well as the strict requirements on overall size and weight. Specifically, to solve the watertightness problem of the motor and other equipment, a sealing cylinder composed of a front sealing cover, a sealing cylinder, and a rear sealing cover is designed, exhibiting good integrity and compactness. Furthermore, to reduce volume and weight while meeting strength requirements, in addition to using high-strength materials such as titanium alloy, the impeller structure is designed to closely connect with the dimensions of the sealing cylinder, and a double-supported simply supported beam structure is adopted, greatly reducing the overall size and weight of the towing winch and achieving the goal of lightweight design.
[0044] In summary, the cylindrical support type towing winch impeller of the present invention firstly encapsulates the motor inside the cylinder, serving to fix and seal the motor; secondly, the flange at the rear of the cylinder is fastened to the towing winch mounting frame, thus fixing the entire cylinder in place; finally, the supporting flange in the middle of the cylinder provides support for the bushing and spokes, eliminating potential strength hazards of the cantilever structure. Therefore, it has good integrity and strength, and greatly improves the compactness of the structure.
[0045] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
