Description

Technical Field

[0001] The present invention relates to the technical field of underwater sealed electric cylinders, and in particular to a driving source device based on reversing transmission. Background Art

[0002] A drive source device based on reversing transmission usually refers to a system that connects the power source through a certain mechanical structure (such as a belt, chain or gear) to achieve reversing rotation. In the electric cylinder device, this type of structure is mainly used to transmit the linear or rotational motion of the power source to the electric cylinder, while changing the direction of motion or transmission ratio as needed to adapt to specific application scenarios. The following are the key points of this device: Power source: Common power sources include servo motors, stepper motors or AC / DC motors. Reversing transmission system: Such as pulleys, chain drives or gear sets, which can achieve reversing or speed changes according to design requirements. Electric cylinder body: Linear output is achieved through screws, ball screws or linear guides. Control system: Used to adjust the direction of motion, speed and positioning accuracy.

[0003] The driving source device based on reversing transmission is widely used on ships, mainly including the following aspects; Steering system: underwater electric cylinders are usually used to control the steering system of ships to help ships turn and maneuver. Through the power and motion control provided by the electric cylinder, the steering system can accurately adjust the rudder angle, thereby affecting the direction and navigation path of the ship. Valve control: underwater electric cylinders can be used to control various valves on ships, such as cabin valves, water tank valves, radiator valves, etc. Through the movement of the electric cylinder, the opening and closing of these valves can be remotely controlled to control the operating status of various systems on the ship.

[0004] In the marine environment, the application of electric cylinders needs to pay special attention to waterproof performance, because ships are often in high humidity, salt spray and vibration environments, and may face the risk of water splashing, soaking or moisture erosion. If the waterproof performance is insufficient, the electronic components of the electric cylinder will be damaged, and the mechanical structure will rust or fail. Especially in the contact area between the power source and the conversion device, this part of the area cannot be sealed in a fully enclosed manner because the output end of the power source must rotate. There must be a certain gap, which makes it easy for water to enter when the water pressure is too high. The existing drive source device based on reversing transmission has done a lot of work on the outer shell sealing of the conversion device and the electric cylinder body, but the protection of the rotating part of the power source and the connection between the power conversion device is not in place.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a driving source device based on reversing transmission to solve the above technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is to design a driving source device based on reversing transmission, which is needed to be used on board a ship, and to design the seal between the power source output end and the reversing transmission device, thereby making up for the shortcomings of the prior art in this field.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0008] A driving source device based on reversing transmission, comprising a driving motor, a sealing mechanism, a reversing driving box, a telescopic cylinder and a hook;

[0009] The output end of the driving motor is arranged on the side of the reversing driving box, and the reversing driving box is used to transmit the rotational motion of the driving motor to the telescopic cylinder through the driving wheel, the driven wheel and the belt, and at the same time change the motion direction or the transmission ratio as needed, so as to realize the rapid extension and retraction of the telescopic cylinder, and the sealing mechanism is installed inside the reversing driving box;

[0010] The sealing ring in the sealing mechanism intercepts the water entering from the side of the reversing drive box, and the rotating assembly collects and controls the water entering from the gap between the contact surface and the rotating rod, and confines it in the water storage chamber under the action of centrifugal force;

[0011] The telescopic cylinder is installed on the other side of the reversing drive box. The telescopic cylinder converts the rotational motion of the driven wheel into the linear motion of the telescopic cylinder through a ball screw or the like. The hook is installed at the outermost end of the telescopic cylinder. The hook is used to connect other components to facilitate expansion work.

[0012] The sealing mechanism comprises a rotating rod, a sealing assembly, a fixing assembly and a rotating assembly;

[0013] The rotating rod is installed at the output end of the driving motor, and the two ends of the rotating rod are respectively fixed on the output end of the driving motor and the active rotor, and is a component connecting the driving motor and the active rotor. The sealing component is installed on the side of the reversing drive box, and the sealing component is used to isolate the outside world and the reversing drive box to prevent water from entering. The fixed component is installed around the sealing component. The fixed component reduces the gap between the sealing component and the reversing drive box by pressing down the sealing component to ensure the sealing performance. The rotating component is installed on the rotating rod, and the rotating component rotates with the rotating rod. On the one hand, the stability of the rotation is improved, and on the other hand, the water is intercepted to prevent it from further entering the reversing drive box.

[0014] The sealing assembly includes a sealing ring, a positioning ring, a contact surface, a clamping ring and a mounting groove; the sealing ring is installed on the side of the reversing drive box, and the sealing ring is used to isolate the reversing drive box from the outside world; the positioning ring is installed on the top of the sealing ring, and the positioning ring is used to reinforce the structure of the sealing assembly and help the rotating rod to be positioned; the clamping ring is installed below the sealing ring, and the clamping ring is used to be clamped in the reversing drive box; the mounting groove is arranged on the inner side of the sealing ring, and the mounting groove is used to accommodate the part of the rotating ring in the rotating assembly; the sealing ring, the positioning ring and the clamping ring are set to rubber materials, and the rubber material can achieve better sealing under pressure conditions; the sealing ring radius value is set to 1.2 times the clamping ring radius value, so as to set a larger transition zone to prevent water from entering from below the sealing ring; the contact surface is provided with a wear-resistant metal coating, and the contact surface is the direct contact area between the sealing assembly and the rotating rod. The use of wear-resistant materials helps to extend the service life; the mounting groove is set to a ring shape to accommodate the rotating ring.

[0015] The fixing assembly includes a fixing block, a connecting elbow, a connecting block, a fixing pin and a supporting spring; the fixing block is installed on the side of the reversing drive box, the lower end of the connecting elbow is installed on the fixing block, the other end of the connecting elbow is installed with a connecting block, the fixing pin is installed under the connecting block, the fixing pin is fixed inside the reversing drive box, and the fixing effect of the sealing assembly is ensured, and the supporting spring is installed under the connecting block. The vertical height value of the connecting elbow is less than the height value of the supporting spring, so that the supporting spring is always in a compressed state, and because the fixing block is fixed on the surface of the reversing drive box, the supporting spring can always apply downward pressure to the sealing assembly to ensure that the gap between the sealing assembly and the reversing drive box is reduced.

[0016] The rotating assembly includes a rotating ring, a mounting block and a water inlet; the rotating ring is mounted on the outer surface of the rotating rod, and the mounting block is mounted on the rotating ring. The mounting block is arranged in a ring shape. On the one hand, the mounting block is used to be clamped in the mounting groove to ensure the compactness of the structure, thereby improving the sealing performance. On the other hand, the cross-sectional shape of the mounting block is arranged in a right-angled trapezoid, thereby intercepting the incoming water and making it flow into the water inlet; the water inlet is opened on the rotating ring, and the water inlet is responsible for inputting the incoming water into the water storage chamber for collection and storage.

[0017] The rotating assembly also includes a water storage chamber, an air storage chamber and an oil storage chamber; the water storage chamber, the air storage chamber and the oil storage chamber are sequentially opened inside the rotating ring from the inside to the outside, the water storage chamber is used to store the collected water to prevent it from overflowing and affecting other structures, the air storage chamber is provided with gas to help adjust the balance of the cavities on both sides, and the oil storage chamber is placed with lubricating oil, which can be delivered to the rotating groove during rotation. On the one hand, it is difficult to disassemble the reversing drive box frequently for maintenance in underwater use scenarios, which may cause the sealing to deteriorate. This design can ensure the lubrication between the rotating ring and the reversing drive box, and on the other hand, sufficient lubricating oil will enhance the sealing between the rotating ring and the reversing drive box. There are 2-4 groups in the vertical direction, and adjacent water storage chambers are connected to each other to ensure that a larger space for water can be provided.

[0018] The rotating assembly also includes a rotating groove, a rotating ball and an oil outlet; the rotating groove is opened on the side of the rotating ring, and the setting of the rotating groove can improve the rotation stability of the rotating ring. A sufficient amount of lubricating oil is arranged inside the rotating groove, and the sealing effect can be further achieved through an oil seal. Through the combination of multiple rotating grooves and a reversing rotating box, it can be ensured that the axis position during the rotation process will not be offset. The rotating ball is arranged inside the rotating groove, and the rotating ball is used to reduce the friction during the rotation process. The oil outlet is opened in the middle of adjacent rotating balls, and the oil outlet is used to input lubricating oil into the rotating groove. One end of the oil outlet is connected to the oil storage chamber.

[0019] The reversing drive box includes a protective shell, a driving wheel, a driven wheel and a belt; the protective shell is set as the main part of the reversing drive box, and the protective shell is produced by an integrated forming process such as casting, so as to reduce the possibility of water ingress, the driving wheel is installed inside the protective shell, the active rotation and the rotation rod are connected, the driven wheel is installed next to the driving wheel, the size of the driving wheel and the driven wheel can be set as needed to meet different usage requirements, the belt is installed on the outer surface of the driving wheel and the driven wheel, and the belt is used to connect the driving wheel and the driven wheel to achieve reversing.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The present invention significantly improves the sealing performance and stability between the sealing component and the reversing drive box by providing a sealing mechanism and adopting a multi-level and multifunctional protective structure. By providing a fixing component, the sealing component can fit the reversing drive box more closely, thereby effectively preventing the infiltration of external moisture or other impurities. At the connection between the rotating rod and the reversing drive box, the present invention introduces a rotating ring structure, which can intelligently collect a small amount of moisture that may enter. The rotating ring can not only effectively collect and store moisture, but also prevent the moisture from further overflowing or entering the internal mechanical structure through its special design, thereby protecting the core components in the reversing drive box.

[0022] (2) In addition, in order to solve the problem of insufficient lubrication that may result from long-term operation, the present invention provides an oil storage chamber. The oil storage chamber can automatically replenish the rotating groove by precisely controlling the release of lubricating oil, thereby ensuring that the lubrication system is always in the best condition and reducing friction and wear during mechanical operation. This design greatly improves the operating efficiency and service life of the equipment. In order to further enhance the sealing effect, the present invention adopts a design scheme of multiple continuous oil seals. Through this design, multiple barriers are formed, and moisture is blocked after passing through the first oil seal. Even if a small amount of moisture breaks through, the subsequent oil seals can continue to function, ensuring that the inside of the reversing drive box always remains dry.

[0023] (3) The present invention is particularly suitable for application scenarios such as ships that require strict sealing performance, especially the sealing requirements between the power source output end and the reversing transmission device. This innovative design makes up for the shortcomings of the existing technology in this field, not only improving the waterproof performance of the equipment, but also enhancing the reliability and operational stability of the overall system, meeting the urgent needs of modern ship equipment for high-performance sealing systems.

DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1-9As shown, a driving source device based on reversing transmission integrates components such as a driving motor 1, a sealing mechanism 2, a reversing driving box 3, a telescopic cylinder 4 and a hook 5, and realizes efficient power transmission and multifunctional expansion through a compact structural design. The output end of the driving motor 1 is set on the side of the reversing driving box 3, and the rotary motion is transmitted to the telescopic cylinder 4 through the active runner 32, the driven runner 33 and the belt 34, while supporting the adjustment of the motion direction and the transmission ratio to meet different work requirements. The sealing mechanism 2 is located inside the reversing driving box 3, and its sealing ring 221 can effectively intercept the water inflow from the side, while the rotating component 24 captures the water that penetrates into the gap between the contact surface 223 and the rotating rod 21, and guides it to the water storage chamber 244 by centrifugal force, ensuring that the water will not spread or damage the internal structure. The telescopic cylinder 4 is installed on the other side of the reversing driving box 3, and the rotary motion is converted into linear motion by means of a ball screw, etc., to achieve efficient and accurate telescopic operation. The hook 5 component at its end is used to connect other components to provide good expansibility. The device has a compact structure, strong sealing, and high power transmission efficiency. It is suitable for a variety of scenarios such as automation equipment and marine machinery. It performs particularly well in environments with high requirements for waterproofing and dustproofing, making up for the shortcomings of traditional drive devices in terms of sealing and transmission flexibility.

[0038] like Figure 3 As shown, the sealing mechanism 2 is composed of a rotating rod 21, a sealing component 22, a fixed component 23 and a rotating component 24, which is intended to ensure the sealing and stability of the reversing drive box 3, prevent water or other external substances from entering the system, and maintain the efficient operation of the drive system.

[0039] The rotating rod 21 is installed at the output end of the driving motor 1 and is a key component connecting the driving motor 1 and the driving wheel 32. The two ends of the rotating rod 21 are respectively fixed to the output end of the driving motor 1 and the driving wheel 32. During operation, the rotating rod 21 assumes the main function of power transmission, and transmits the power of the motor to the driving wheel 32 through its stable rotation. Since the design of the rotating rod 21 requires it to withstand greater pressure and frequent rotation, its material and structure must have good strength and durability.

[0040] The sealing component 22 is installed on the side of the reversing drive box 3. The main function of the sealing component 22 is to isolate the external environment from the communication between the reversing drive box 3 and prevent external moisture or impurities from entering the drive system. The sealing component 22 is usually made of a highly sealing material, which can withstand high pressure or humid environment, and effectively prevent moisture penetration, protecting the internal mechanical parts from corrosion or damage. The sealing component 22 is precisely designed to ensure sealing while adapting to dynamic changes of the equipment.

[0041] The fixing assembly 23 is installed around the sealing assembly 22, and the sealing performance is further enhanced by pressing down. The fixing assembly 23 ensures that the gap between the sealing assembly 22 and the reversing drive box 3 is reduced, thereby effectively improving the sealing effect and preventing the sealing assembly 22 from being displaced or failing due to long-term use. The stable installation of the fixing assembly 23 also improves the structural strength of the entire sealing system, so that it can still maintain normal operation under high load conditions.

[0042] The rotating assembly 24 is mounted on the rotating rod 21 and rotates synchronously with the rotation of the rotating rod 21. The rotating assembly 24 has two main functions: first, by improving the stability of the rotation, it ensures the stable connection between the rotating rod 21 and the active rotating wheel 32; second, the rotating assembly 24 also plays a role in intercepting moisture, preventing water or other liquids from further entering the reversing drive box 3. This design effectively improves the adaptability of the reversing drive box 3 in harsh environments and reduces the potential threat of external moisture to the internal system.

[0043] like Figure 4 As shown, the sealing mechanism 2 is composed of a rotating rod 21, a sealing component 22, a fixed component 23 and a rotating component 24, and has a compact structure design and clear functions, which effectively improves the sealing performance and operating stability of the device.

[0044] The rotating rod 21 is a key connecting member between the driving motor 1 and the driving wheel 32. One end of the rotating rod 21 is fixed to the output end of the driving motor 1, and the other end is fixed to the driving wheel 32. By accurately transmitting the rotational motion of the motor, the subsequent mechanism is driven to operate efficiently. The high strength and wear resistance of the rotating rod 21 ensure stability during high-speed operation, and provide a solid foundation for the installation of the sealing mechanism 2.

[0045] The sealing component 22 is installed on the side of the reversing drive box 3 to isolate the external environment from the internal structure, effectively preventing external moisture or dust from entering the reversing drive box 3. Its design focuses on achieving efficient sealing, especially providing reliable protection in humid or watery environments. The material of the sealing component 22 is corrosion-resistant and high-temperature-resistant, and can withstand the test of harsh environments for a long time.

[0046] like Figure 5 As shown, the fixing assembly 23 is installed around the sealing assembly 22, and adopts a downward pressure design, so that the sealing assembly 22 can fit the surface of the reversing drive box 3 more closely. By reducing the gap between the sealing assembly 22 and the reversing drive box 3, the fixing assembly 23 effectively improves the sealing performance of the entire sealing mechanism 2, avoiding leakage problems caused by looseness or excessive gaps. At the same time, the fixing assembly 23 enhances the impact resistance of the sealing assembly 22, and adapts to working conditions with frequent vibrations or load fluctuations.

[0047] The rotating assembly 24 is mounted on the rotating rod 21, and rotates synchronously with the rotating rod 21, playing multiple functions. On the one hand, it significantly improves the stability of the rotating rod 21 through a special structural design, reduces shaking and mechanical stress during operation, and ensures the high efficiency and continuity of power transmission; on the other hand, the rotating assembly 24 can effectively intercept water, especially for a small amount of water entering from the gap between the rotating rod 21 and the sealing assembly 22, through the centrifugal force generated during rotation, it is blocked outside or guided to a specific water storage area, further protecting the inside of the reversing drive box 3 from water damage.

[0048] Through the cooperation of the rotating rod 21, the sealing assembly 22, the fixed assembly 23 and the rotating assembly 24, the entire sealing mechanism 2 forms a highly integrated protection system, which not only ensures the sealing performance, but also takes into account the operational stability and reliability of the equipment. This design is particularly suitable for industrial scenarios that require high sealing and high durability, such as ship machinery, transmission equipment in humid environments, etc., making up for the shortcomings of the traditional sealing mechanism 2 in terms of stability and environmental adaptability.

[0049] The sealing assembly 22 has a compact structure and multiple functions, and is mainly composed of a sealing ring 221, a positioning ring 222, a contact surface 223, a clamping ring 224 and a mounting groove 225. The various parts cooperate with each other to achieve efficient sealing and stable installation of the reversing drive box 3.

[0050] The sealing ring 221 is installed on the side of the reversing drive box 3. Its main function is to isolate the inside of the reversing drive box 3 from the outside world, effectively preventing moisture, dust or other impurities from entering the internal precision structure. The sealing ring 221 is made of rubber material. With its flexibility and adaptability to pressure changes, it can provide a stable sealing effect under different working conditions and meet the use requirements of the equipment in high humidity or high temperature environments.

[0051] The positioning ring 222 is located on the top of the sealing ring 221, and is used to enhance the overall structural strength of the sealing assembly 22, while providing accurate positioning support for the rotating rod 21 to ensure its stability and concentricity during operation. The design of the positioning ring 222 enables the sealing assembly 22 to remain reliably fixed when subjected to mechanical vibration or other external forces, and is not easy to shift, thereby improving the long-term operating performance of the equipment.

[0052] The clamping ring 224 is installed at the bottom of the sealing ring 221, and is used to firmly clamp the sealing assembly 22 in the reserved position of the reversing drive box 3. The radius value of the clamping ring 224 is accurately calculated, and the ratio of the radius value of the clamping ring 224 to the radius value of the sealing ring 221 is 1:1.2. This difference design forms a larger transition area, which can effectively prevent moisture from penetrating from under the sealing ring 221. The elastic properties of the rubber material enable the clamping ring 224 to fit closely to the inner surface of the reversing drive box 3 during installation, thereby enhancing the sealing performance.

[0053] The contact surface 223 is the direct contact area between the sealing assembly 22 and the rotating rod 21. In order to improve durability, a wear-resistant metal coating is provided on its surface. This coating can not only effectively reduce the friction and wear generated during the rotation process, but also prevent deformation or sealing performance degradation during long-term use, thereby extending the service life of the sealing assembly 22. The contact surface 223 further improves the functionality of the sealing ring 221 by precisely matching with the rotating rod 21.

[0054] The mounting groove 225 is provided on the inner side of the sealing ring 221 and is designed in an annular shape to accommodate the rotating ring 241 in the rotating assembly 24. The annular structure of the mounting groove 225 ensures the stable positioning of the rotating ring 241 and prevents loosening or dislocation caused by high-speed rotation or external force. In addition, the design of the mounting groove 225 enhances the cooperative working effect between the sealing assembly 22 and the rotating assembly 24, so that the entire device maintains high efficiency and tight sealing during operation.

[0055] In general, the design of the sealing assembly 22, through the ingenious combination of the sealing ring 221, the positioning ring 222, the clamping ring 224, the contact surface 223 and the mounting groove 225, not only realizes the sealing protection of the reversing drive box 3, but also takes into account the durability and installation stability of the assembly. The dual application of rubber material and wear-resistant metal further enhances the reliability and adaptability of the sealing assembly 22. This sealing assembly 22 is particularly suitable for complex industrial scenes that require waterproofing and dustproofing, and can significantly improve the service life and operating efficiency of the equipment, while making up for the shortcomings of traditional sealing structures in durability and environmental adaptability.

[0056] The fixing assembly 23 includes a fixing block 231, a connecting elbow 232, a connecting block 233, a fixing pin 234 and a supporting spring 235; the fixing block 231 is installed on the side of the reversing drive box 3, the lower end of the connecting elbow 232 is installed on the fixing block 231, the other end of the connecting elbow 232 is installed with a connecting block 233, the fixing pin 234 is installed below the connecting block 233, the fixing pin 234 is fixed inside the reversing drive box 3, and the fixing effect of the sealing assembly 22 is ensured, and the supporting spring 235 is installed below the connecting block 233. The vertical height value of the connecting elbow 232 is less than the height value of the supporting spring 235, so that the supporting spring 235 is always in a compressed state, and because the fixing block 231 is fixed on the surface of the reversing drive box 3, the supporting spring 235 can always apply downward pressure to the sealing assembly 22, so as to reduce the gap between the sealing assembly 22 and the reversing drive box 3.

[0057] like Figure 7-8As shown, the rotating assembly 24 includes a rotating ring 241, a mounting block 242 and a water inlet 243, and has a compact and reasonable structural design, which aims to improve the sealing performance of the device and achieve effective treatment of incoming moisture.

[0058] The rotating ring 241 is installed on the outer surface of the rotating rod 21 and rotates synchronously with the rotating rod 21. As the core part of the rotating assembly 24, the rotating ring 241 can not only enhance the stability of the rotating rod 21, but also provide an additional protection layer for the sealing system, effectively preventing water from intruding into the interior by guiding moisture.

[0059] The mounting block 242 is arranged above the rotating ring 241 and adopts a ring-shaped design. On the one hand, the mounting block 242 ensures the stability and compactness of the entire structure by snapping into the mounting groove 225, thereby further improving the sealing performance; on the other hand, the cross-sectional shape of the mounting block 242 is designed to be a right-angled trapezoid. This unique structure can effectively intercept the water infiltrated from the outside and prevent it from freely diffusing, while guiding the water to the water inlet 243 to achieve precise control.

[0060] The water inlet 243 is provided at the top of the rotating ring 241 to receive the water guided by the mounting block 242. The water entering the water flows into the water storage chamber 244 through the water inlet 243 for centralized collection and storage, so as to prevent the water diffusion from damaging the internal precision structure.

[0061] The rotating assembly 24 realizes the dual functions of sealing and water treatment through the cooperation of the rotating ring 241, the mounting block 242 and the water inlet 243, provides a guarantee for the stable operation of the equipment in a humid environment, and demonstrates the design advantages of high efficiency and reliability.

[0062] The rotating assembly 24 also includes a water storage chamber 244, an air storage chamber 245 and an oil storage chamber 246, which are sequentially opened inside the rotating ring 241 from the inside to the outside, forming a multifunctional liquid and gas management system to ensure the stable operation of the equipment in harsh environments.

[0063] The water storage chamber 244 is located in the innermost layer and is mainly used to store collected water. This water usually comes from the gap between the rotating assembly 24 and the sealing structure, and is collected in the water storage chamber 244 through the guidance of the rotating ring 241. The design of the water storage chamber 244 not only ensures that water will not overflow and affect other key structures, but also effectively prevents moisture from damaging the equipment. Through this water collection function, the presence of water can be better managed and the risk of equipment failure in a humid environment can be reduced.

[0064] The air storage chamber 245 is located outside the water storage chamber 244 and contains gas. The main function of the air storage chamber 245 is to help adjust the balance of the chambers on both sides and maintain the stability of the internal pressure. Since the rotating assembly 24 may generate pressure fluctuations during operation, the air storage chamber 245 can effectively buffer these fluctuations, ensuring that the device remains balanced and stable under various operating conditions, thereby preventing sealing problems or mechanical failures caused by uneven pressure.

[0065] The oil storage chamber 246 is located at the outermost layer and contains lubricating oil, which is designed to deliver lubricating oil to the rotating groove 247 during the rotation process. The delivery of lubricating oil not only ensures the smooth operation between the rotating ring 241 and the reversing drive box 3, but also reduces friction and wear. Especially in underwater or humid environments, since it is difficult to regularly disassemble and maintain the reversing drive box 3, this automatic lubrication design ensures the lubricity of the equipment during long-term operation, and avoids the reduction of sealing and equipment damage caused by insufficient lubrication. In addition, sufficient lubricating oil can also enhance the sealing between the rotating ring 241 and the reversing drive box 3, effectively extending the service life.

[0066] In the vertical direction, the water storage chamber 244, the air storage chamber 245 and the oil storage chamber 246 are designed to be arranged adjacent to each other in 2-4 groups and interconnected through a common structure. This design not only provides a larger water storage space, but also increases the capacity of the chamber, ensuring that water can be effectively collected and stored during long-term operation while maintaining the stability of the system. This innovative design allows the rotating component 24 to maintain excellent sealing and lubricity even in frequent rotations and complex environments, greatly improving the reliability and durability of the equipment.

[0067] The rotating assembly 24 also includes a rotating groove 247, a rotating ball 248 and an oil outlet 249. These structures work together to significantly improve the stability and operating efficiency of the rotating assembly 24, ensuring the long-term reliability of the equipment under high loads and harsh environments.

[0068] The rotating groove 247 is provided on the side of the rotating ring 241 and is ingeniously designed. Its main function is to improve the rotation stability of the rotating ring 241. During the rotation process, the rotating groove 247 provides storage space for the lubricating oil, thereby ensuring that the lubricating oil can be evenly distributed and maintain a stable lubrication effect. In addition, the structure of the rotating groove 247 helps to achieve sealing through an oil seal, prevent lubricating oil leakage, and reduce friction and wear. The precise combination of the multiple rotating grooves 247 and the reversing drive box 3 ensures that the axial position of the rotating ring 241 will not be offset during the rotation process, thereby improving the stability and operation accuracy of the rotating ring 241.

[0069] The rotating ball 248 is arranged inside the rotating groove 247, and its main function is to reduce the resistance caused by friction during the rotation process. As an efficient rolling element, the rotating ball 248 can effectively reduce the contact friction between the rotating ring 241 and the rotating groove 247, reduce energy loss, and improve the efficiency and life of the overall rotating system. The use of the rotating ball 248 also reduces mechanical wear and extends the service life of the sealing assembly 22.

[0070] The oil outlet 249 is located between adjacent rotating balls 248 and plays a vital role. The design of the oil outlet 249 can ensure that the lubricating oil is continuously input into the rotating groove 247, providing sufficient lubrication for the rotating ring 241, reducing friction and temperature rise, and thus ensuring the smooth operation of the system. One end of the oil outlet 249 is connected to the oil storage chamber 246 to form a closed lubricating oil circuit. Through this circuit, the lubricating oil is continuously circulated and transported, ensuring the flow and replenishment of the lubricating oil in the entire system, avoiding the depletion of the lubricating oil, and maintaining the long-term stability of the system.

[0071] In summary, the ingenious design of the rotating groove 247, the rotating ball 248 and the oil outlet 249 not only ensures the stable operation of the rotating assembly 24, but also prolongs its service life through effective lubrication and friction control. The combination of these structures enables the rotating assembly 24 to maintain high efficiency and low wear performance under high load and high frequency working conditions, and is particularly suitable for industrial equipment requiring high reliability and complex working environments.

[0072] like Fig. 9 As shown, the reversing drive box 3 is composed of a protective shell 31, a driving wheel 32, a driven wheel 33 and a belt 34, and each part is precisely matched to ensure the efficient operation and sealing performance of the entire drive system.

[0073] The protective shell 31 is the main part of the reversing drive box 3, and plays a role in protecting the internal components. The protective shell 31 is produced by an integrated molding process such as casting, which can ensure that the structure of the protective shell 31 is more solid, avoid seams or weak links, and effectively reduce the possibility of water ingress, ensuring the normal operation of the device in a humid or underwater environment. Through the integrated design, the sealing of the protective shell 31 is greatly improved, reducing the risk of external moisture or other impurities entering the interior.

[0074] The driving wheel 32 is installed inside the protective shell 31 and is directly connected to the rotating rod 21, responsible for transmitting the rotational motion of the drive motor 1 to the entire system. The design of the driving wheel 32 enables it to stably transmit power, and at the same time cooperates with the driven wheel 33 to achieve efficient motion conversion. The rotation of the driving wheel 32 cooperates with the rotating rod 21, so that the reversing drive box 3 can run smoothly and provide sufficient power output.

[0075] The driven wheel 33 is installed next to the driving wheel 32, and its size can be adjusted according to actual needs to meet the load requirements in different usage scenarios. The size and relative position of the driving wheel 32 and the driven wheel 33 determine the transmission ratio and movement mode, so it can be customized according to the needs of the equipment to ensure the flexibility and adaptability of the drive system.

[0076] The belt 34 is installed on the outer surface of the driving wheel 32 and the driven wheel 33, and is responsible for connecting the two and transmitting power. The use of the belt 34 ensures smooth transmission of power and realizes the reversing function by changing the direction of rotation. The material and tension of the belt 34 are carefully designed to ensure that it can maintain stable performance during long-term operation, reduce wear and improve transmission efficiency.

[0077] Through these sophisticated designs, the reversing drive box 3 not only ensures efficient power transmission, but also has better sealing and durability, adapts to various complex working environments, and ensures the long-term reliable operation of the equipment.

[0078] The waterproof sealing principle of the present invention is as follows: the fixing block 231 is installed on the side of the reversing drive box 3, the fixing pin 234 is installed inside the reversing drive box 3, and the supporting spring 235 presses down the sealing ring 221 to reduce the gap between the sealing ring 221 and the reversing drive box 3 to ensure the sealing performance;

[0079] When the water pressure is high, the area between the rotating rod 21 and the contact surface 223 may not be completely sealed. A small amount of water enters the reversing drive box 3, is intercepted by the mounting ring in the mounting groove 225, and enters the water storage chamber 244 through the water inlet 243, ensuring that it will not overflow to other places. Even if a small amount of water enters the outer side of the rotating ring 241 from the gap between the mounting ring and the mounting groove 225, it will be intercepted by the lubricating oil in the rotating groove 247, thereby ensuring the sealing of this part.

[0080] The driving motor 1 works, driving the rotating rod 21 to rotate, and the rotating ring 241 installed on it rotates accordingly. The lubricating oil inside the oil storage chamber 246 enters the rotating groove 247 through the oil outlet 249 under the action of centrifugal force to automatically fill the lubricating oil, thereby reducing the number of maintenance times and ensuring the sealing of the reversing drive box 3 as much as possible.

Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the widest scope consistent with the principles and novel features disclosed herein.
