Description

A kind of shield of propeller

Technical field

The utility model belongs to technical field of ships, is related to a kind of shield of propeller.

Background technique

Ship is a kind of man made transportation tools mainly run in geographical water.

In addition, inercant ships are commonly referred to as ship, naval ship is known as warship, and small boat is known as ship or boat, is collectively referred to as naval vessel or ship Ship；Internal mainly includes accommodation space, support construction and discharge structure, has the propulsion system using the external or included energy, External form is usually the cleanliness envelope for being conducive to overcome fluid resistance, and material is constantly updated with scientific and technological progress, be in early days wood, bamboo, The nature materials such as fiber crops, modern age are mostly steel and aluminium, glass fibre, acrylic and various composite materials.

Existing propeller for vessels during use, be easy snarled by water plant so that the use of propeller compared with It for difficulty, and then results in propeller and stops operating, cause that ship is inconvenient to use, and the problem that stability is bad.

Summary of the invention

The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of protection of propeller Cover, technical problem to be solved in the utility model is how propeller not to be snarled by water plant.

The purpose of this utility model can be realized by the following technical scheme:

A kind of shield of propeller, including mounting plate, the mounting plate are equipped with propeller, if the propeller includes A dry blade, which is characterized in that shield is covered on the propeller, offered on the bottom plate of the shield several every Plate, forms inlet opening between two adjacent partitions, and the partition is equipped with several blades, the inlet opening and shield Inner cavity is connected to, and is equipped with steel knife on the blade, the steel knife can be rotated with the rotation of blade, and the shield is equipped with Retaining ring is connected between the mounting plate and retaining ring by fastener.

Working principle: first will be covered with shield on propeller so that during use, can by large-scale water plant or Person's impurity snarls, since retaining ring is connect with fastener, so that shield can be driven to rotate during propeller rotational, this When the blade that is equipped with of shield small water plant can be cut and is crushed, while part enters the water plant of shield inner cavity, It can further be cut by the steel knife on blade, under double action, realize to ship in use, avoid Propeller is not snarled by water plant, further improves the stability that propeller uses, while also improving the use of propeller Service life.

In the shield of above-mentioned propeller, there are three the blade is set, three blades along partition length direction Setting.

In the shield of above-mentioned propeller, the steel knife is positioned close to the side of bottom plate.

In the shield of above-mentioned propeller, the partition is equipped with eight, and eight partitions uniformly divide along bottom plate is circumferential Cloth.

In the shield of above-mentioned propeller, width of the partition close to the center of circle of bottom plate is less than partition far from bottom plate The center of circle width.

Compared with prior art, the shield of this propeller has the advantage that: in the blade of partition and the steel knife of propeller Double action under, realize to ship in use, avoid propeller and do not snarled by water plant, further improve spiral shell The stability that rotation paddle uses.

Specific embodiment

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figure 1, the shield of this propeller, including mounting plate 1, mounting plate 1 are equipped with propeller 2, propeller 2 is wrapped Include several blades 21.

Specifically, as depicted in figs. 1 and 2, it is covered with shield 3 on propeller 2, is offered on the bottom plate of shield 3 Several partitions 31, form inlet opening 32 between two adjacent partitions 31, and partition 31 is equipped with several blades 33, inlet opening 32 are connected to the inner cavity 34 of shield 3, and steel knife 22 is equipped on blade 21, and steel knife 22 can be rotated with the rotation of blade 21, Shield 3 is equipped with retaining ring 35, is connected between mounting plate 1 and retaining ring 35 by fastener 4.

Working principle: first will be covered with shield 3 on propeller 2, so that during use, it can be by large-scale water plant Or impurity snarls, since retaining ring 35 is connect with fastener 4, so that shield 3 can be driven during propeller 2 rotates Rotation, the blade 33 that shield 3 is equipped at this time can be cut and are crushed to small water plant, while part enters shield 3 The water plant of inner cavity 34 can further be cut by the steel knife 22 on blade 21, under double action, realize and exist to ship It in use process, avoids propeller 2 and is not snarled by water plant, further improve the stability that propeller 2 uses, while Improve the service life of propeller 2.

As depicted in figs. 1 and 2, there are three blade 33 is set, three blades 33 are arranged along the length direction of partition 31.

As depicted in figs. 1 and 2, steel knife 22 is positioned close to the side of bottom plate.

As depicted in figs. 1 and 2, partition 31 is equipped with eight, and eight partitions 31 are circumferentially uniformly distributed along bottom plate.

As depicted in figs. 1 and 2, partition 31 is less than the width in the center of circle of the partition 31 far from bottom plate close to the width in the center of circle of bottom plate Degree.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
