The to-be-solved technical problem of the utility model lies in overcoming the not enough of prior art, provides a novel screw protection casing, for solving above-mentioned technical problem, the utility model discloses a technical scheme's basic concept is:
the utility model provides a novel propeller protective cover, includes a bottom steel strip that has toughness, bottom steel strip is the ring form, and its end to end department forms the breach, bottom steel strip is located the fixed welding of the relative rear side surface of breach has a bow-shaped skeleton, and bow-shaped skeleton is located breach top branch and has two bow-shaped frame tributaries, and the below of two bow-shaped frame tributaries welds with the end to end department of bottom steel strip respectively, the end to end department below of bottom steel strip still is provided with the nut that matches each other, the fixed welding in bottom steel strip ring week has a plurality of supports, and the upper end of support all welds the formation cover body through bow-shaped skeleton.
The support includes that the integrative outside spreader bar that makes progress that bends and inwards concentrates the pole, and both junctions present the streamlined of arcuation, and the lower extreme fixed welding that makes progress outside spreader bar takes in the bottom billet, and the upper end leans out, the upper end an organic whole of the outside spreader bar that upwards is provided with inwards concentrates the pole, the upper end leanin of inwards concentrating the pole just is fixed in on the bow-shaped skeleton.
And elastic plates which are symmetrically arranged are fixed on the inner side surfaces of the head and the tail of the bottom steel strip.
After the technical scheme is adopted, compared with the prior art, the utility model following beneficial effect has.
With this device cover in the screw outside of ship, press the head and the tail department of bottom steel strip for the breach that it formed is sealed, then carries out spacing fixed in two nuts through the bolt screw in, accomplishes the installation back, can effectively avoid the screw to stir into pasture and water or collide the foreign matter in rotating, the effectual screw body that has protected.
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Drawings

In the drawings:
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the back side of the present invention.
In the figure: 1-bottom steel strip; 2-an arched framework; 3-a scaffold; 4-a nut; 5-an elastic plate; 21-a bow-shaped frame; 31-upward outward expansion rod; 32-inwardly centering rod.
It should be noted that the drawings and the description are not intended to limit the scope of the inventive concept in any way, but to illustrate the inventive concept by those skilled in the art with reference to specific embodiments.
Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments, and the following embodiments are used for illustrating the present invention, but do not limit the scope of the present invention.
As shown in fig. 1 to 2, a novel propeller protection cover, including a bottom steel strip 1 that has toughness, this steel strip 1 can be the lath, also can be the reinforcing bar form, bottom steel strip 1 is the ring form, its head and the tail department forms the breach, bottom steel strip 1 is located the relative rear side surface fixed welding of breach and has a bow-shaped skeleton 2, and bow-shaped skeleton 2 is located breach top branch and has two bow-shaped frame tributaries 21, and the below of two bow-shaped frame tributaries 21 welds with the head and the tail department of bottom steel strip 1 respectively, bottom steel strip 1's head and the tail department below still is provided with the nut 4 of mutual matching, the fixed welding of 1 all circles of bottom steel strip has a plurality of supports 3, and the upper end of support 3 all welds through bow-shaped skeleton 2 and forms the cover body. With this device cover in the screw outside of ship, press the head and the tail department of bottom steel strip 1 for the breach that it formed is sealed, then carries out spacing fixed in two nuts 4 through the bolt screw in, accomplishes the installation back, can effectively avoid the screw to stir into pasture and water or collide the foreign matter in rotating, the effectual screw body that has protected.
In order to reduce the hull and go in this protection casing to the resistance that rivers led to the fact, design into integrative outside flaring 31 and the inside central rod 32 that bends and form with support 3, both junctions present the streamline of arcuation, the lower extreme fixed welding of the outside flaring 31 of making progress is on bottom steel strip 1, the upper end leans out, the upper end an organic whole of the outside flaring 31 of making progress is provided with inside central rod 32, the inside slope of the upper end of the pole 32 of inwards concentrating just is fixed in on bow-shaped skeleton 2, the design can receive the water resistance like this.
In this example, the inner side surfaces of the head and the tail of the bottom steel strip 1 are fixed with the elastic plates 5 which are symmetrically arranged, so that in the installation process, the bottom steel strip 1 is installed on the base of the propeller after sealing the gap, and the compactness is increased.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
