Description

Technical Field

[0001] The utility model relates to the technical field of impellers, and more particularly to an impeller for a bare pump type ship propeller. Background Art

[0002] A ship is a means of transportation that can sail or anchor in waters for transportation or operations. Early ships were generally made of natural materials such as wood, bamboo, and hemp, and required human power to drive them. With the advancement of technology, ships are now mostly made of steel, aluminum, fiberglass, acrylic, and various composite materials, and are generally equipped with a propeller. The propeller is generally equipped with a rotating impeller. The rotation of the impeller continuously pushes the water backward, and the reaction force generated by the water pushing backward makes the ship move.

[0003] The shortcomings of the existing technology: When the existing impeller is in use, the blades are easily damaged when they hit relatively hard objects due to the high-speed rotation, and water plants and long objects in the water are easily entangled on the impeller, causing the impeller to not rotate normally, affecting the movement of the ship. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an impeller for a bare pump type ship propeller to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: an impeller for a bare pump type ship propeller, comprising a drive shaft, an impeller placed on the outside of the drive shaft, a protective sleeve fixedly connected to the outside of the impeller, the protective sleeve comprising a sleeve body, a connecting column fixedly connected to the outside of the sleeve body, and a cutting ring fixedly connected to the top of the connecting column.

[0006] Preferably, the right sides of the sleeve body and the cutting ring are both arranged obliquely.

[0007] Preferably, the drive shaft includes a shaft body, a column is fixedly connected to the left side of the shaft body, a column groove is provided on the outside of the column, a clamping block is movably connected to the inside of the column, the left side of the column is set as an arc surface, and a first spring is fixedly connected between the clamping block and the shaft body.

[0008] Preferably, the impeller includes a shaft sleeve, a clamping plate is movably connected inside the shaft sleeve, a block groove is provided on the left side of the shaft sleeve, a shaft groove is provided inside the shaft sleeve, a blade is fixedly connected to the outside of the shaft sleeve, and a second spring is fixedly connected between the clamping plate and the shaft sleeve.

[0009] Preferably, the outer sides of the drive shaft, the protective sleeve and the impeller are all coated with an anti-oxidation layer.

[0010] Preferably, the transverse length of the impeller is smaller than the transverse length of the protective sleeve.

[0011] Technical effects and advantages of this utility model:

[0012] 1. The utility model is provided with a protective sleeve, which is beneficial to protecting the impeller and reducing the possibility of collision between the impeller and hard objects. The impeller drives the protective sleeve to rotate through the rotation of the drive shaft, and then the cutting ring rotates. The edge of the cutting ring is relatively sharp, and foreign matter can be cut during rotation to prevent foreign matter from being entangled on the outside of the propeller, ensuring that the ship can move better. The right sides of the sleeve and the cutting ring are both obliquely arranged to reduce the resistance to its forward movement.

[0013] 2. The utility model is convenient for the installation of the impeller by providing a drive shaft and an impeller. During installation, the plug post is aligned with the shaft groove and inserted into it. During insertion, the block will contact the shaft sleeve. Through continuous insertion, the block will be retracted into the interior of the plug post, thereby enabling the plug post to be further inserted into the shaft sleeve. After that, the plug post squeezes the card plate, and the card plate is retracted into the interior of the shaft sleeve by squeezing, so that the plug post can be fully inserted into the shaft sleeve. After the plug post is fully inserted into the shaft sleeve, the card plate can be inserted into the column groove under the action of the second spring, further preventing the plug post from rotating. At the same time, the block will extend under the action of the first spring, thereby limiting the impeller, so that the impeller is fixed, and the block is in the block groove after being extended and retracted, further preventing the plug post from rotating, thereby ensuring the stability of the connection between the drive shaft and the impeller, and being relatively simple to install.

The rotation of the drive shaft 1 causes the impeller 3 to drive the protective sleeve 2 to rotate, thereby causing the cutting ring 203 to rotate. The edge of the cutting ring 203 is relatively sharp, and foreign matter can be cut during rotation to prevent foreign matter from being entangled on the outside of the propeller, thereby ensuring that the ship can move better.

[0021] Furthermore, the right sides of the sleeve body 201 and the cutting ring 203 are both arranged obliquely. By arranging the right sides of the sleeve body 201 and the cutting ring 203 obliquely, the forward resistance can be lowered.

[0022] Furthermore, the drive shaft 1 includes a shaft body 101, and a column 102 is fixedly connected to the left side of the shaft body 101. A column groove 103 is provided on the outside of the column 102. A clamping block 104 is movably connected to the inside of the column 102. The left side of the column 102 is set as an arc surface. A first spring 105 is fixedly connected between the clamping block 104 and the shaft body 101. The column groove 103 is used for inserting the clamping plate 302. The clamping block 104 can be extended and retracted inside the column 102. The left side of the clamping block 104 is set as an arc, and it can be retracted into the interior of the column 102 by squeezing its left side. The column 102 is a hexagonal prism structure, which can drive the impeller 3 to rotate after being inserted.

[0023] Furthermore, the impeller 3 includes a sleeve 301, which is movably connected to a clamping plate 302 inside the sleeve 301, a block groove 305 is provided on the left side of the sleeve 301, and a shaft groove 304 is provided inside the sleeve 301. The outer side of the sleeve 301 is fixedly connected to a blade 303, and a second spring 306 is fixedly connected between the clamping plate 302 and the sleeve 301. The shaft groove 304 is used for inserting the column 102, and the clamping plate 302 can be extended and retracted inside the sleeve 301. The inner edge of the clamping plate 302 is set as an arc, and the clamping plate 302 can be retracted into the interior of the sleeve 301 by squeezing. During installation, the column 102 is aligned with the shaft groove 304 and inserted into it. During insertion, the clamping block 104 will contact the sleeve 301, and the clamping block 104 will be retracted into the interior of the column 102 through continuous insertion. , thereby allowing the plug post 102 to be further inserted into the shaft sleeve 301, and then the plug post 102 squeezes the card plate 302, and through squeezing, the card plate 302 is retracted into the interior of the shaft sleeve 301, so that the plug post 102 can be completely inserted into the shaft sleeve 301. After the plug post 102 is completely inserted into the shaft sleeve 301, the card plate 302 is inserted into the column groove 103 under the action of the second spring 306, further preventing the plug post 102 from rotating. At the same time, the block 104 will extend under the action of the first spring 105, thereby limiting the impeller 3, so that the impeller 3 is fixed, and the block 104 is in the block groove 305 after being extended, further preventing the plug post 102 from rotating, ensuring the stability of the connection between the drive shaft 1 and the impeller 3, and the installation is relatively simple.

[0024] Furthermore, the outer sides of the drive shaft 1, the protective sleeve 2 and the impeller 3 are coated with an anti-oxidation layer to ensure a longer service life.

[0025] Furthermore, the transverse length of the impeller 3 is smaller than the transverse length of the protective sleeve 2, so that the impeller 3 can be completely inside the protective sleeve 2, ensuring that it can better protect the impeller 3 and has a certain noise reduction effect.

[0026] The working principle of the present invention is as follows: when in use, the impeller 3 is installed first, the plug post 102 is aligned with the shaft groove 304 and inserted into it, the block 104 contacts the shaft sleeve 301 during insertion, and the block 104 is retracted into the interior of the plug post 102 through continuous insertion, so that the plug post 102 can be further inserted into the shaft sleeve 301, and then the plug post 102 squeezes the card plate 302, and the card plate 302 is retracted into the interior of the shaft sleeve 301 through squeezing, so that the plug post 102 can be completely inserted into the shaft sleeve 301, and after the plug post 102 is completely inserted into the shaft sleeve 301, the card plate 302 can be inserted into the column groove 103 under the action of the second spring 306, further preventing the plug post 102 from rotating, and the block 104 It will extend under the action of the first spring 105, and then limit the impeller 3, so that the impeller 3 is fixed, and the block 104 is in the block groove 305 after being extended, further preventing the plug column 102 from rotating, ensuring the stability of the connection between the drive shaft 1 and the impeller 3, and it is relatively simple to install. The sleeve 201 has a certain strength, and the impeller 3 is inside it, which can protect the impeller 3 and reduce the possibility of it colliding with hard objects. The rotation of the drive shaft 1 causes the impeller 3 to drive the protective sleeve 2 to rotate, and then causes the cutting ring 203 to rotate. The edge of the cutting ring 203 is relatively sharp, and it can cut foreign matter when rotating to prevent foreign matter from being entangled on the outside of the propeller, ensuring that the ship can move better.
