Abstract
The utility model discloses a protective screening of a propeller of a ship, which comprises a screen arranged at the periphery of the propeller and connected with the bottom of the ship, wherein the screen comprises a bottom protective screening of the propeller arranged below the propeller and a transmission shaft and a rear protective screening of the propeller arranged at the rear of the propeller, and the bottom protective screening and the rear protective screening are connected mutually and are respectively connected with the bottom of the ship. In the utility model, the screen is arranged at the periphery of the propeller of the ship, thus not affecting the function of the water flow and the propeller and preventing foreign bodies from impacting the propeller, and weeds, fishing nets and other sundries are difficult to contact with and wind the propeller, so that the service life of the propeller and the driving safety of the ship are guaranteed.
Description
Technical field
The utility model relates to a kind of grille guard, is specifically related to a kind of propeller for vessels grille guard.
Background technology
Usually, the driving engine of boats and ships is arranged on afterbody, and driving engine is connected with screw propeller through transmission shaft, and the screw propeller of some spitkits normally exposes bottom behind hull, and there is following potential safety hazard in the process of moving in this ship:
1, easy with the water-bed bumps such as stone of screw propeller when the shoal, screw propeller is broken easily;
2, when foreign material such as weeds or fishing net are arranged in the river course, be wrapped in easily on the screw propeller, increase the weight of engine load, even screw propeller can't be rotated.
Therefore, the screw propeller of existing spitkit need install fender guard additional, make screw propeller be not easy to receive the foreign matter impact damage, and foreign material such as weeds or fishing net also is not easy to be wrapped on the screw propeller.
Summary of the invention
In view of this, the utility model provides a kind of propeller for vessels grille guard, make boats and ships in the process of moving screw propeller be not easy to receive the foreign matter impact damage, and foreign material such as weeds or fishing net also are not easy to be wrapped on the screw propeller.
The propeller for vessels grille guard of the utility model, comprise be arranged on screw propeller peripheral and with hull bottom bonded assembly guard.
Further; Said guard comprises the screw propeller foot guard net and the screw propeller rear portion grille guard that is arranged at rear propeller that is arranged at screw propeller and transmission shaft below, and said screw propeller foot guard net interconnects with screw propeller rear portion grille guard and is connected with hull bottom respectively;
Further; Said screw propeller rear portion grille guard is a semicircular ring; The semicircular ring two ends be connected with hull bottom and ring body to extending below; Said screw propeller foot guard net comprises that an end is connected with semicircular ring and the other end extends axially back and hull bottom bonded assembly fender rod along semicircular ring, and said fender rod is evenly spaced apart along the semicircular ring circumferencial direction;
Further, the interval arc length of said fender rod on semicircular ring is 10 ~ 20cm;
Further, said semicircular ring is the semicircle reinforced steel bar ring, and said fender rod is a reinforcement rod.
The beneficial effect of the utility model is: the utility model is provided with guard in the screw propeller periphery of boats and ships; Neither influence the effect of current and screw propeller; Can stop foreign matter bump screw propeller again; And foreign material such as weeds or fishing net also are not easy to contact screw propeller, are not easy to be wrapped on the screw propeller, have guaranteed the life-span and the ship running safety of screw propeller.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the main TV structure scheme drawing of the utility model;
Fig. 2 is the backsight structural representation of the utility model.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.
Fig. 1 is the main TV structure scheme drawing of the utility model, and Fig. 2 is the backsight structural representation of the utility model, and is as shown in the figure, the propeller for vessels grille guard of the utility model, comprise be arranged on screw propeller 2 peripheral and with hull 3 bottom bonded assembly guards 1.
In the present embodiment; Said guard 1 comprises screw propeller foot guard net 11 that is arranged at screw propeller 2 and transmission shaft 4 belows and the screw propeller rear portion grille guard 12 that is arranged at screw propeller 2 rears, and said screw propeller foot guard net 11 interconnects with screw propeller rear portion grille guard 12 and is connected with hull 3 bottoms respectively.
In the present embodiment; Said screw propeller rear portion grille guard 12 is a semicircular ring; The semicircular ring two ends be connected with hull 3 bottoms and ring body to extending below; Said screw propeller foot guard net 11 comprises that an end is connected with semicircular ring and the other end extends axially back and hull 3 bottom bonded assembly fender rods along semicircular ring, and said fender rod is evenly spaced apart along the semicircular ring circumferencial direction.
In the present embodiment, the interval arc length of said fender rod on semicircular ring is 10 ~ 20cm.
In the present embodiment, said semicircular ring is the semicircle reinforced steel bar ring, and said fender rod is a reinforcement rod.
Certainly, guard is not limited to said structure, but it should have certain intensity to support, and the size of the eyelet on the guard, gap etc. suitably, neither influences the effect of current and screw propeller, can stop foreign matters such as stone, weeds, fishing net again.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the preferred embodiment through with reference to the utility model is described the utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of the utility model that does not depart from appended claims and limited.
