Preferably, the face of joint that the footpath by hole makes progress along rudder stock of left half cover and right half cover is sealed engagement face.
Preferably, rudder stock is provided with seal ring by the week edge in hole, and sealing circle is set on rudder stock hermetically.
Preferably, seal ring is government rubber seal ring.
Preferably, the face of joint between sealing protection cover and the top planes of rudder blade assembly is sealed engagement face.
Preferably, in protective cover, fill with and have lubricating oil.
Preferably, the top of left half cover and/or right half cover is provided with the filling oilhole for filling lubricating oil.
Preferably, the bottom of left half cover and/or right half cover is provided with for discharging the outage of lubricating oil.
Pass through technique scheme, on the flap type rudder that the utility model provides, be provided with sealing protection cover, sealing protective cover covers at the top of transmission component and extends downward the top planes of rudder blade assembly, so just can avoid ship floating debris in water in the process of work to be wound into transmission component completely and also can avoid the damage of the things such as silt to transmission component completely, what extended flap type rudder is service life.Sealing protection cover is Split type structure and removably connects simultaneously, simple in structure, easily fitting operation.
Other feature and advantage of the present utility model partly in detail are described the specific embodiment subsequently.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
The utility model provides a kind of flap type rudder, as shown in Figure 2, flap type rudder comprises rudder stock assembly 1, rudder blade assembly 2 and the transmission component 3 between rudder stock assembly 1 and rudder blade assembly 2, flap type rudder also comprises sealing protection cover 5, and sealing protective cover 5 covers at the top of transmission component 3 and extends downward the top planes of rudder blade assembly 2.As shown in Figure 3, rudder stock assembly 1 comprises rudder stock 4, is formed with rudder stock by hole 8 on the end face of sealing protection cover 5, the footpath along rudder stock by hole 8 upwards, the left side that protective cover 5 forms Split type structure partly cover 7 and the right side partly cover 6, a left side is partly covered 7 and is partly covered 6 with the right side and removably connect.In other words, a left side partly cover 7 and the right side partly cover and on 6, be formed with respectively a semi-circular recesses, two semi-circular recesses are combined into described rudder stock by hole 8, left partly cover 7 and right partly cover 6 faying face at rudder stock by the radial face in hole 8.
In prior art, the structure of flap type rudder as shown in Figure 1, comprise rudder stock assembly 1, rudder blade assembly 2 and the transmission component 3 between rudder stock assembly 1 and rudder blade assembly 2, this transmission component 3 is exposed to outside completely, ship floating debris in water in traveling process twines easily around entering transmission component 3, the things such as while silt are also to transmission component being caused to damage, and what shortened flap type rudder is service life.The utility model arranges sealing protection cover 5 on flap type rudder, has avoided ship floating debris in water in the process of work to be wound into transmission component 3 completely and also can avoid the damage of the things such as silt to transmission component completely, and what extended flap type rudder is service life.Sealing protection cover is Split type structure and removably connects simultaneously, simple in structure, easily fitting operation.Left partly cover 7 and right 6 the faying face of partly covering overlap with the cross-sectional plane that the footpath by hole 8 makes progress along rudder stock, can guarantee that, in the working process of ship, sealing protection cover 5 has excellent stability.
In the present embodiment, the noise producing in order to reduce sealing protection cover in ship process 5, preferably, left partly cover 7 with right 6 the face of joint that the footpath by hole 8 makes progress along rudder stock of partly covering be sealed engagement face.In order further to reduce noise, more preferably, rudder stock is provided with seal ring by the week edge in hole 8, and sealing circle is set on rudder stock 4 hermetically.In order further to reduce noise, still more preferably, the face of joint between sealing protection cover 5 and the top planes of rudder blade assembly 2 is sealed engagement face.Wherein, in order to make seal ring more durable in use, preferably seal ring is government rubber seal ring.
In the present embodiment, in order to reduce the loss in transmission component 3 working processs, preferably, the interior filling of protective cover 5 has lubricating oil.Lubricating oil just can play lubricating effect like this, to reduce the loss of transmission component 3.
In the present embodiment, for the ease of inject lubricating oil in sealing protection cover 5, preferably, left partly cover 7 and/or right 6 the top of partly covering be provided with the filling oilhole for filling lubricating oil.
