Description

Technical Field

[0001] The utility model belongs to the technical field of propeller protection, and particularly relates to a propeller protection cover for a rescue boat. Background Art

[0002] During water rescue, when a rescue boat is traveling in the water for rescue work, since the water area often contains obstacles such as stones, waterweeds, fishing nets, etc., the external engine propeller of the boat is easily hit by stones or entangled by waterweeds and fishing nets during the rotation process; in addition, when rescue personnel are performing rescue tasks underwater, the propeller is also very likely to cause harm to the rescue personnel, resulting in injury accidents. The above situations will also cause damage to the propeller, bringing many inconveniences to the rescue process.

[0003] Chinese Patent with application number CN202021910187.6 discloses a new type of propeller protection cover, which includes a bottom steel strip with toughness. The bottom steel strip is circular, with a notch formed at the head and tail. A bow-shaped skeleton is fixedly welded on the rear surface of the bottom steel strip opposite to the notch. The bow-shaped skeleton branches into two bow-shaped frame brackets above the notch, and the lower parts of the two bow-shaped frame brackets are respectively welded to the head and tail of the bottom steel strip. Nuts that match each other are also provided below the head and tail of the bottom steel strip. A plurality of brackets are fixedly welded around the circumference of the bottom steel strip, which can effectively prevent the propeller from being entangled in waterweeds or colliding with obstacles during rotation and protect the propeller. However, this device has problems of insecure connection with the propeller and poor protection effect during actual use, and has poor applicability, which limits its application range. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a propeller protection cover for a rescue boat, which is an outboard engine propeller protection cover with convenient installation, easy disassembly and better protection effect, in response to the increasingly complex water rescue situation, so as to effectively solve the problems existing in the prior art.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A propeller protection cover for a rescue boat includes a protection cover, and the protection cover includes a propeller front guard ring and a propeller rear guard ring. The propeller front guard ring and the propeller rear guard ring are fixedly connected by evenly distributed side rods. The propeller front guard ring is provided with front guard rods that diverge outward. The other ends of the front guard rods are centrally connected to the outside of the propeller front guard ring. The front guard rods are overall spindle-shaped. A vertical reinforcing plate device is fixedly connected to the propeller front guard ring, and a water knife plate is fixedly connected to the front end of the reinforcing plate device.

[0007] As a further configuration of the above scheme, the propeller front guard ring includes a front upper guard ring and a front lower guard ring, both of which are semicircular, the front upper guard ring is parallel to the propeller rear guard ring and the center of the circle coincides with that of the propeller rear guard ring, the lower side of the front lower guard ring is close to the propeller rear guard ring, and the horizontal projection of the front lower guard ring coincides with that of the propeller rear guard ring.

[0008] As a further configuration of the above scheme, the reinforcement plate device includes a reinforcement plate, which is in a broken line shape as a whole. The reinforcement plate is parallel to the front guard ring of the propeller, and the bending part of the reinforcement plate is fixedly connected to the outer end of the front guard rod. An upper splint is provided at the upper end of the reinforcement plate, and the other end of the upper splint is fixedly connected to the rear guard ring of the propeller. The upper splint separates the rear guard ring of the propeller, and a middle splint and a lower splint are provided in sequence below the upper splint, which are parallel to each other and horizontally arranged.

[0009] As a further configuration of the above solution, snap-fit ​​buckle plates are symmetrically arranged at the lower ends of both side surfaces of the upper clamping plate.

[0010] As a further configuration of the above solution, the protective cover is made of magnesium alloy, and the overall weight of the protective cover is light and the structural strength is high.

[0011] The working principle of the utility model is as follows: Figure 2 As shown, the existing propeller mechanism includes a propeller body, an outer machine center axis plate, a water pressure plate and a connecting plate. During installation, align the upper clamping plate with the connecting plate front to back, and place the upper clamping plate above the water pressure plate, align the snap-fitting plate with the water pressure plate front to back, push the protective cover, the connecting plate enters the upper clamping plate and abuts against the rear side of the reinforcing plate, the snap-fitting plate is engaged with the water pressure plate, and at the same time, the middle clamping plate and the lower clamping plate clamp the outer machine center axis plate at the same time, and one end of the middle clamping plate and the lower clamping plate stick out of the outer machine center axis plate, and the propeller body is just located in the protective cover, and the upper clamping plate, the middle clamping plate and the lower clamping plate are locked with bolts, and the upper clamping plate, the middle clamping plate and the lower clamping plate are fixed to the outer machine center axis plate and the connecting plate, so that the entire protective cover is fixed to the propeller mechanism, and the protective cover protects the propeller body; When working, the propeller body rotates to push the rescue boat forward. The propeller front guard ring, propeller rear guard ring and side rods protect the sides of the propeller body. At the same time, the propeller front guard ring, front guard rod and reinforcement plate device are overall a shuttle shape with the tip forward. While protecting the front of the propeller body, it is beneficial to reduce water flow resistance and reduce power loss. The water jet plate can contact the underwater obstacles in advance to play a protective role, and can also cut and divert obstacles to prevent obstacles from hanging on the front end of the protective cover or being drawn into the propeller body, thereby ensuring the stable operation of the propeller mechanism; the protective cover is made of magnesium alloy and is welded as a whole. It has the characteristics of light weight and high structural strength.

[0012] The utility model has the following beneficial effects:
