Abstract
The utility model discloses a fishing net prevention structure for a propeller shaft of a small-sized boat. The fishing net prevention structure for the propeller shaft of the small-sized boat is simple in structure and small in resistance, and is capable of effectively preventing a fishing net from being coiled into a propeller. The fishing net prevention structure for the propeller shaft of the small-sized boat comprises the propeller shaft (1), a bearing pedestal (2), a sealing device (3) and the propeller (4), wherein the front end of the propeller shaft (1) is connected a coupler of an engine, the bearing pedestal (2), the sealing device (3) and the propeller (4) are connected with the rear end of the propeller shaft (1) in a sleeved mode in sequence. A supporting plate (5) is fixedly connected between the bearing pedestal (2) and a boat body. A fishing net separating plate (6) is arranged on the bearing pedestal (2). The lower end face of the fishing net separating plate (6) is lower than the lowest point of blades of the propeller (4). The fishing net prevention structure for the propeller shaft of the small-sized boat can be applied to the field of shipbuilding.
Description
Technical field
The utility model relates to a kind of small watercraft stern-shaft anti-fish-net structure.
Background technology
In the boats and ships operational process, in case fishing net is rolled on the screw propeller, can cause screw propeller to stop operating or damage, enter sealing arrangement lip place if be involved in fishing net by screw propeller simultaneously along rear bearing block, can make sealing arrangement reduce service life even destruction, finally cause seal failure, therefore be necessary to adopt anti-fishing net device.The present anti-fishing net device that uses, structure and stern shaft seal gland are quite similar, have just done some changes on seal ring, can not fundamentally solve fishing net and be involved in screw propeller in-to-in technical matters, and have defectives such as weak point in service life, difficult replacing, so do not obtain promoting.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, resistance is little, can prevent effectively that fishing net is involved in the small watercraft stern-shaft anti-fish-net structure in the screw propeller.
The technical scheme that the utility model adopted is: the utility model comprises the stern tube shaft that front end is connected with the driving engine coupler and is socketed on rear bearing block, sealing arrangement, the screw propeller of described stern tube shaft rear end successively, be fixedly connected with stay bearing plate between described rear bearing block and the hull, described rear bearing block is provided with the fishing net dividing plate, and described fishing net dividing plate lower surface is lower than the blade nadir on the described screw propeller.
Be provided with an arc transition face between the front end face of described fishing net dividing plate and its lower surface.
The front end face of described fishing net dividing plate be the projection arc surface and thereafter end face be provided with cutting edge portion.The beneficial effects of the utility model are: the utility model comprises the stern tube shaft that front end is connected with the driving engine coupler and is socketed on rear bearing block, sealing arrangement, the screw propeller of described stern tube shaft rear end successively, be fixedly connected with stay bearing plate between described rear bearing block and the hull, described rear bearing block is provided with the fishing net dividing plate, and described fishing net dividing plate lower surface is lower than the blade nadir on the described screw propeller.In the time of ship's navigation, described fishing net dividing plate can be pressed in fishing net under water, because described fishing net dividing plate lower surface is lower than the blade nadir on the described screw propeller, does not contact with fishing net so can guarantee described screw propeller, can guarantee effectively that boats and ships normally move.
Further, be provided with an arc transition face between the front end face of described fishing net dividing plate and its lower surface, described arc transition face can make the easier underwater that is pressed onto of fishing net, thereby can not be suspended on the described fishing net dividing plate.
Further, the front end face of described fishing net dividing plate for the projection arc surface and thereafter end face be provided with cutting edge portion, if fishing net is involved in wherein by described screw propeller, in order to prevent that fishing net from further twining under the drive of described screw propeller, cause to be corrupted to sealing arrangement, this cutting edge can be cut the fishing net that is wound.
Description of drawings
Fig. 1 is the structural representation of small watercraft stern-shaft anti-fish-net structure;
Fig. 2 is the cutaway view of small watercraft stern-shaft anti-fish-net structure.
Specific embodiment
Shown in Fig. 1 ~ 2, the utility model comprises stern tube shaft 1 that front end is connected with the driving engine coupler and the rear bearing block 2 that is socketed on described stern tube shaft 1 rear end successively, sealing arrangement 3, screw propeller 4, be fixedly connected with stay bearing plate 5 between described rear bearing block 2 and the hull 8, be fixedly connected with fishing net dividing plate 6 under the described rear bearing block 2, described fishing net dividing plate 6 lower surfaces will be lower than the blade nadir 50CM on the described screw propeller 4, when ship's navigation, described fishing net dividing plate 6 can be pressed in fishing net under water, guarantee that described screw propeller 4 does not contact with described fishing net dividing plate 6, can guarantee that boats and ships normally move.Be provided with an arc transition face 7 between the front end face of described fishing net dividing plate 6 and its lower surface, the front end face of described fishing net dividing plate 6 for the projection arc surface and thereafter end face be provided with cutting edge portion 9, if fishing net is involved in wherein by described screw propeller, in order to prevent that fishing net from further twining under the drive of described screw propeller, cause to be corrupted to sealing arrangement, this cutting edge can be cut the fishing net that is wound.
Claims (3)
1. small watercraft stern-shaft anti-fish-net structure, comprise that the stern tube shaft (1) that front end is connected with the driving engine coupler reaches rear bearing block (2), sealing arrangement (3), the screw propeller (4) that is socketed on described stern tube shaft (1) rear end successively, be fixedly connected with stay bearing plate (5) between described rear bearing block (2) and the hull (8), it is characterized in that: described rear bearing block (2) is provided with fishing net dividing plate (6), and described fishing net dividing plate (6) lower surface is lower than the blade nadir on the described screw propeller (4).
2. small watercraft stern-shaft anti-fish-net structure according to claim 1 is characterized in that: be provided with an arc transition face (7) between the front end face of described fishing net dividing plate (6) and its lower surface.
