Description

Technical Field

[0001] The utility model relates to the technical field of marine escape capsules, in particular to a hydraulic control drive device for marine escape capsules. Background Art

[0002] In traditional hydraulic control systems for marine escape pods, common technical solutions typically combine a simple gear transmission structure with a linear hydraulic drive. The typical design includes a rotating handle and a set of gear assemblies, which transmit the rotational motion to the hydraulic device through mechanical force, driving the plunger or piston to produce pressure changes to achieve steering control of the escape pod. However, traditional gear transmissions are mostly direct meshing transmissions, which are prone to problems such as unstable meshing, rapid gear wear, and loose connections. Especially under emergency operations and high loads, the transmission efficiency and stability are poor. In addition, the plungers inside the hydraulic drive device mostly reciprocate in a straight line, which cannot effectively reduce frictional resistance, and the system's response speed and stability are insufficient.

[0003] In existing traditional hydraulic control devices, the connection between gears and shafts mostly adopts a simple direct meshing design. During long-term use or high-intensity operation, problems such as loose connections and poor gear meshing are prone to occur. This not only reduces transmission efficiency and causes operational lags, but also increases wear on the transmission system and shortens the service life of the device. Therefore, in emergency situations, traditional devices find it difficult to achieve fast and precise hydraulic control, affecting the safety and reliability of the escape pod. In view of this, research and improvements are conducted on the existing problems, and a hydraulic control drive device for marine escape pods is provided to solve the current problems. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Utility Model Content

[0010] In a preferred embodiment, the present invention can be further configured such that an adjustable stopper is provided on the inner side of the plunger rod. The stopper controls the flow rate and pressure of the fluid by adjusting the plunger rod's stroke length to meet the hydraulic requirements under different operating conditions. By adopting the above technical solution, by adding an adjustable stopper on the inner side of the plunger rod, the plunger rod's stroke length can be flexibly adjusted, thereby precisely controlling the hydraulic flow rate and pressure, adapting to various operating environments, and improving the system's applicability and accuracy.

[0011] In a preferred embodiment, the present invention can be further configured such that the one-way liquid outlet groove is an elongated through-hole structure, which is used to maintain communication between the plunger rod's inner cavity and the liquid outlet nozzle during the plunger rod's movement.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] Example 1:

[0025] The present invention provides a hydraulically controlled drive device for a marine escape pod, comprising a drive base 100, a hydraulic control assembly 200, a rotor 300, and several plunger rods 400 located inside the hydraulic control assembly 200. The rotor 300 is rotatably mounted inside the drive base 100, with an inclined guide plate 310 provided on one side of the rotor 300. A steering gear 110, designed to connect to a steering column, is rotatably mounted on the surface of the drive base 100. The steering gear 110 meshes with one end of the rotor 300 for transmission. This design transmits steering operations to the rotor 300, achieving hydraulic control.

[0026] The hydraulic control assembly 200 includes a pump cylinder 210, a hydraulic sensor assembly 220, and a plurality of piston cylinders 230 located inside the pump cylinder 210. A liquid inlet 211 and a liquid outlet 212 are provided on both sides of the pump cylinder 210, wherein one end of the liquid inlet 211 is connected to the end of the piston cylinder 230 to form a hydraulic channel. A liquid guide hole is provided on the surface of the piston cylinder 230, which is located in the middle and connected to the end of the liquid outlet 212, for the inflow and outflow of liquid. A one-way liquid inlet 410 and a one-way liquid outlet groove 420 are provided on the surface of the plunger rod 400, and a one-way valve is provided on the inner side of the plunger rod 400 for liquid flow between the one-way liquid outlet groove 420 and the one-way liquid inlet 410 to ensure that the liquid can only flow in one direction, thereby improving the accuracy of hydraulic control.

[0027] Working effect: Through the coordination between the various components, this design enables the rotation to be stably transmitted to the rotor 300 when operating the steering gear 110, thereby controlling the movement of the plunger rod 400, ensuring the effective transmission and reliability of the hydraulic pressure.

[0028] Example 2:

[0029] In this embodiment, the present invention further improves the design of the rotor 300 to enhance the sensitivity of hydraulic control and the smoothness of operation. Specifically, the surface of the rotor 300 is designed as a bevel structure, and the inclined guide plate 310 is arranged at an angle, so that the plunger rod 400 can closely abut the surface of the inclined guide plate 310 during the sliding process. At this time, the rotor 300 and the inclined guide plate 310 are connected by a flat shaft plate 311, ensuring that the plunger rod 400 can slide smoothly during the movement. This design enables the plunger rod 400 to perform uniform reciprocating motion on the inclined surface, reducing frictional resistance and ensuring a smoother fluid flow.

[0030] The plunger rod 400 is sheathed with a spring. One end of the spring slides over the inner side of the piston cylinder 230, while the other end is fitted with a brim located on the outer periphery of the arc-shaped hemispherical surface. The two ends of the spring abut against the brim and the surface of the hydraulic control assembly 200, respectively. During use, the spring's elasticity ensures that the plunger rod 400 automatically resets after each movement, enhancing the device's continuous operation capability.

[0031] In addition, the hydraulic pressure sensing assembly 220 is fixed to the surface of the pump cylinder 210, and its input end is connected to the end of the piston cylinder 230. This allows real-time monitoring of the hydraulic pressure inside the piston cylinder 230, ensuring that the hydraulic pressure state can be accurately controlled and monitored during use.

[0032] Working Effect: By designing the plunger rod 400 to mate with the inclined guide plate 310, the plunger rod 400 ensures smoother movement and reduces mechanical losses within the system. Furthermore, the automatic reset function of the spring structure enhances the continuous operation of the hydraulic control device. Furthermore, the monitoring function of the hydraulic sensor assembly 220 enables dynamic monitoring of the hydraulic system, improving safety and accuracy.

[0033] Additional improved features:

[0034] One end of the rotor 300 is provided with a key shaft that meshes with the steering gear 110. The steering gear 110 has a larger diameter than the key shaft. This design ensures stability during the meshing transmission process, prevents loose connections, and ensures that the device maintains high transmission efficiency and stability over long-term use.

[0035] An adjustable stopper is located inside the plunger rod 400. By adjusting the position of the stopper, the stroke length of the plunger rod 400 can be controlled, thereby adjusting the flow rate and pressure of the fluid. This design can adapt to the hydraulic requirements of different working conditions and enhance the operational flexibility of the system.

[0036] The one-way liquid outlet groove 420 is designed as a long through-hole structure to ensure that the inner cavity of the plunger rod 400 and the liquid outlet pipe port 212 can always be connected during the movement of the plunger rod 400, so that the liquid can flow in and out smoothly without blockage or insufficient flow.

[0037] Working effect: The key shaft design ensures the reliability and durability of the mechanical transmission; the adjustable limiter enables the hydraulic device to be flexibly adjusted to adapt to different hydraulic needs; the design of the long through-hole structure ensures the stability and smoothness of the liquid flow, improving the overall performance of the hydraulic system.

[0038] Through the detailed description of the two embodiments above, this utility model expands and supplements the original claims, fully demonstrating its practical application in a hydraulic control system for a marine escape pod. Design improvements in mechanical transmission, fluid flow control, and dynamic monitoring significantly enhance the device's stability, accuracy, and applicability.

[0039] Working principle and usage process: During the manual operation and rotation of the steering column of the escape capsule, the steering gear 110 drives the rotor 300 to rotate inside the drive seat 100, and the spring on the surface of the plunger rod 400 elastically pushes one end of each plunger rod 400 to continuously abut the surface of the inclined guide plate 310. During the rotation of the rotor 300, the inclined inclined guide plate 310 pushes the plunger rod 400 to reciprocate inside the piston cylinder 230. During the return movement of the plunger rod 400, the liquid in the hydraulic pipeline connected to the end of the liquid inlet pipe 211 enters the interior of the piston cylinder 230, and through the forward movement of the plunger rod 400, the liquid flow inside the piston cylinder 230 enters the interior of the plunger rod 400 through the one-way liquid inlet 410, and is guided by the one-way liquid outlet groove 420 under the guidance of the one-way valve, and then guided through the liquid outlet pipe 212. After the liquid outlet pipe 212 is guided, the hydraulic boost is input into the propeller and rudder of the escape capsule for hydraulic steering control.
