Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifeboats, and particularly relates to a highly stable engine system for a lifeboat. Background Technique
[0002] For a free-fall lifeboat, the lifeboat directly falls onto the water surface under the action of gravity from a high place, and the lifeboat will directly bear the impact force generated by the water surface. The existing engines used in lifeboats are directly installed at the bottom inside the boat body through fasteners. The impact force may impact the internal structure of the engine, the connection between the engine and the boat body, and the connection between the engine and the propeller shaft, which may cause problems such as insufficient stability of the engine system and the propeller shaft, thus affecting the normal use of the lifeboat. Content of the Utility Model
[0003] The purpose of the utility model is to provide a highly stable engine system for a lifeboat. Through the design of an outer protection frame and side sliding seats, it can enable the engine to have a sliding trend in the front-back direction at the bottom of the boat. No matter what the angle of the impact force is, it can be transferred into a front-back movement trend. Through the design of spring parts, the impact force can be buffered, so as to protect the engine system from the impact force cancellation, thereby improving the stability and service life of the engine system.
[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0005] The utility model is a highly stable engine system for a lifeboat, which includes a boat body, an engine body, a propeller shaft, an outer protection frame and a group of side sliding seats. The propeller shaft penetrates the tail end of the bottom of the boat body and is connected with a propeller, and the propeller shaft is inclined with respect to the boat body;
[0006] The engine body is fixed inside the outer protection frame. A plurality of horizontal rollers are fixed on the upper part of one opposite side of the outer protection frame through mounting seats, and a plurality of vertical rollers are fixed on the lower part of one opposite side of the outer protection frame;
[0007] The two side sliding seats are respectively arranged on both sides of the outer protection frame. A slide rail body is arranged on the lower part of the inner side of the outer protection frame, and slide seat bodies are arranged at both ends of the upper part of the inner side of the outer protection frame. The vertical rollers roll along the slide rail body, and the horizontal rollers roll along the inner side surface of the side sliding seats;
[0008] The side sliding seats are fixed on the bottom inside the boat body. A rear output end is arranged at the rear side of the engine body, and the rear output end is connected with the end of the propeller shaft through a universal joint coupling, and the height of the rear output end is lower than that of the propeller shaft;
[0009] Guide rods are fixed on the front side and the rear side of the mounting seat. The guide rods penetrate the slide seat bodies and are slidably connected with the slide seat bodies. A spring part sleeved on the guide rods is arranged between the slide seat bodies and the mounting seats.
[0010] Furthermore, the mounting base includes a horizontal plate which is fixed to the outside of the outer protection frame. A number of reinforcing ribs are linearly arranged between the horizontal plate and the outer protection frame, and the guide rod is fixed to the reinforcing ribs.
[0011] Furthermore, it further includes a liquid extraction pump which is fixed to the bottom of the front side of the outer protection frame through a connecting seat. The liquid inlet of the liquid extraction pump is connected with a liquid extraction elbow pipe, and the liquid outlet of the liquid extraction pump is connected with an output hose.
[0012] Furthermore, the slide rail body is of a C-shaped structure, and the distance between the upper edge and the lower edge of the slide rail body is the same as the outer diameter of the vertical roller.
[0013] Furthermore, universal balls are provided at the end of the core shaft of the vertical roller, and the universal balls roll along the inner wall of the slide rail body.
[0014] Furthermore, a number of relief openings for cooperating with the engine body are provided on the outer protection frame, and a number of heat dissipation areas are provided on the outer protection frame.
[0015] The utility model has the following beneficial effects:
[0016] 1. Through the design of the outer protection frame and the side sliding seat, the utility model can enable the engine to have a sliding trend in the front and back directions at the bottom of the boat. No matter what the impact angle is, the impact force can be transferred into a front and back movement trend. Through the design of the spring member, the impact force can be buffered, so as to offset and protect the impact force on the engine system, thereby improving the stability and service life of the engine system.
[0017] 2. The universal joint coupling is used for connecting the engine and the propeller shaft in the utility model, which can indirectly realize the separation between the engine and the propeller shaft. The self-weight of the propeller shaft is small, thus ensuring the stability of the propeller shaft. Similarly, when the engine has a buffer slip, the universal joint coupling can still ensure the connection between the propeller shaft and the engine.
[0018] 3. Through the design of the liquid extraction pump, the utility model can jointly use the driving force of the engine with the propeller shaft to pump the water in the boat body. And the liquid extraction pump does not require a separate power source, which is beneficial to control and has the advantages of energy saving and reducing the occupied space.
[0019] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings
