Description

Technical Field

[0001] The utility model relates to the field of surge power generation, in particular to a transmission guide component used in a surge power generation system. Background Art

[0002] The surge power generation system is a power generation system installed on an offshore platform, which collects surge energy from the waves and converts it into electrical energy for use on the offshore platform. The surge power generation system is equipped with a special-shaped floating body and a transmission guide assembly. The special-shaped floating body floats on the sea and rises and falls with the waves, and drives the transmission guide assembly to swing in the vertical plane. The transmission guide assembly is then connected to the generator through a transmission to convert the swinging mechanical energy into electrical energy. However, in actual use, the transmission guide assembly is not only subject to the force of up and down swinging, but also to the force in the front and back directions. The force in the front and back directions applied to the bearings can easily cause damage to the bearings, reduce the service life of the bearings, and increase maintenance costs.

[0003] Therefore, how to create a new transmission guide assembly for a surge power generation system is one of the current important research and development topics. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a transmission guide assembly for a surge power generation system, so as to limit the displacement of the rotating arm in the front-rear direction, reduce the axial force of the bearing, extend the service life of the bearing, and reduce the maintenance cost, thereby overcoming the shortcomings of the prior art.

[0005] In order to solve the above technical problems, the utility model provides a transmission guide assembly for a surge power generation system, including a support, a swivel arm and a fixed shaft. The swivel arm is connected to the fixed shaft through a bearing so that the swivel arm swings around the fixed shaft. The support has two parallel limit plates. The swivel arm is located in the gap between the two limit plates. A plurality of balls are installed on the side surface of the limit plate facing the swivel arm. The outer surface of the balls abuts against the front and rear side walls of the swivel arm to limit the displacement of the swivel arm in the front and rear directions and allow the swivel arm to swing within the rotation plane.

[0006] As an improvement of the present invention, the balls are arranged in a rectangular array on the side surface of the limiting plate.

[0007] Furthermore, the support also includes a bottom plate, which is connected and fixed to the truss of the offshore platform by bolts.

[0008] Furthermore, the number of the supports is two, and the two supports are symmetrically arranged at equal intervals on the left and right sides of the fixed axis.

[0009] After adopting such a design, the utility model has at least the following advantages:

[0010] 1. By setting a ball on the side of the limit plate of the support, the displacement of the swing arm in the front and rear directions can be effectively limited, thereby reducing the axial force of the bearing, extending the service life of the bearing and reducing maintenance costs;

[0011] 2. The balls are arranged in a rectangular array on the side surface of the limit plate, which can ensure that the rotating arm is in contact with the balls throughout the swing process. The balls can bear the force in the front and rear directions and ensure that the rotating arm can swing smoothly;

[0012] 3. Simple structure, easy to manufacture and install. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The above is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] See also Figure 1 and Figure 2 The utility model provides a transmission guide assembly for a surge power generation system, comprising a rotating arm 1, a fixed shaft 2, a bearing 3, and a support 4.

[0018] The rotating arm 1 is connected to the fixed shaft 2 via a bearing 3 , so that the rotating arm 1 can swing up and down around the fixed shaft 2 in a vertical plane.

[0019] There are two supports 4 , which are symmetrically arranged at equal intervals on the left and right sides of the fixed shaft 2 .

[0020] The support 4 includes a bottom plate limiting plate 41 , a bottom plate 42 and a ball bearing 43 .

[0021] The bottom plate 42 is arranged horizontally and connected and fixed to the truss of the offshore platform by bolts. Two limit plates 41 are welded and fixed on the bottom plate 42. The two limit plates 41 are arranged in parallel with a gap between them. The swing arm 1 is located in the gap between the two limit plates 41, which is used to limit the swing arm 1 in the front and rear directions. A plurality of balls 43 arranged in a rectangular array are installed on the side surface of each limit plate 41 facing the swing arm 1, and the outer surface of the ball 43 abuts against the front and rear side walls of the swing arm 1.

[0022] When the swing arm 1 swings up and down due to the force of the waves, the force in the front-to-back direction is transmitted to the support 4 by the ball 43, reducing the axial force on the bearing 3 and extending the service life of the bearing 3. At the same time, the rolling of the ball 43 can ensure that the swing arm 1 can swing smoothly.

[0023] The utility model has the advantages of simple structure, easy manufacture and convenient installation, prolonging the service life of the bearing, reducing the maintenance cost and ensuring the long-term continuous operation of the surge power generation system.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
