Description

Technical Field

[0001] This utility model relates to the field of fairing technology, specifically to a propeller fairing that is easy to install. Background Technology

[0002] A propeller fairing is a streamlined shell structure installed around a propeller. It is usually made of lightweight, high-strength materials. Its main function is to guide the fluid to flow smoothly through the propeller blades, optimize hydrodynamic performance, reduce turbulence and energy loss, and at the same time protect the propeller, reduce noise and improve propulsion efficiency. It is widely used in propeller systems of equipment such as ships, drones, and underwater robots.

[0003] Currently, in existing technologies, the installation of propeller fairings is cumbersome and requires multiple people to work together, resulting in low installation efficiency. The positioning of the fairings is mostly adjusted manually, which can easily lead to coaxiality deviations, thus affecting the guiding effect. Furthermore, the fairings are prone to loosening and falling off after being subjected to fluid impacts for a long time. In view of this, we propose a propeller fairing that is easy to install. Utility Model Content

[0004] The main objective of this invention is to provide a propeller fairing that is easy to install, thereby solving the problems mentioned in the background section.

A motor is provided on the outer wall of the first connecting cover, and an auxiliary mechanism is provided inside the first connecting cover. The auxiliary mechanism includes a first bevel gear, which is rotatably connected to the inner wall of the first connecting cover and fixedly connected to the output end of the motor.

[0006] Preferably, the first bevel gear meshes with a second bevel gear, the second bevel gear is fixedly connected to a column, and the column is rotatably connected to the inner wall of the outer casing.

[0007] Preferably, a bevel gear three is fixedly connected to the bottom of the column, the bevel gear three meshes with a bevel gear four, the bevel gear four is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the connecting cover two.

[0008] Preferably, the rotating shaft is fixedly connected to a propeller, the outer wall of the connecting cover is fixedly connected to a connecting plate, the connecting plate is provided with an insertion interface and a threaded hole, an L-shaped plate is fixedly connected to the connecting plate, the side wall of the L-shaped plate is provided with a snap-fit ​​interface, and the threaded hole is threaded with a bolt.

[0009] Preferably, the connector is connected to a connector block, the connector block is fixedly connected to a connecting block, and the connecting block is fixedly connected to a flow guide shroud on its side wall.

[0010] Preferably, a movable rod is slidably connected to the side wall of the connecting block, and an auxiliary plate is fixedly connected to the movable rod. The auxiliary plate and the connecting block are connected by a spring. The auxiliary block is fixedly connected to the side wall of the connecting block. By pressing the auxiliary plate, the plug-in block can be aligned with the plug-in interface of the connecting plate and plugged in. After releasing, the spring drives the movable rod and the auxiliary plate to rebound and snap into the locking interface of the L-shaped plate, thus completing the initial positioning of the guide fairing. Then, the guide fairing is reinforced by threaded holes, auxiliary blocks and bolts. The double fixing structure effectively prevents the guide fairing from loosening during operation, greatly simplifies the installation process and improves installation efficiency.

[0011] Preferably, the flow guide is provided with reinforcing ribs.

[0012] This invention provides a propeller fairing that is easy to install.

After releasing, the spring drives the movable rod and the auxiliary plate to rebound and snap into the L-shaped plate's snap interface, thus completing the initial positioning of the fairing. Then, the threaded hole and auxiliary block are used to reinforce the fairing with bolts. The double fixing structure effectively prevents the fairing from loosening during operation, greatly simplifying the installation process and improving installation efficiency.

[0013] (2) The easy-to-install propeller guide fairing uses a motor as a power source to drive bevel gear one and bevel gear two to mesh and rotate in sequence. Then, through the linkage of column, bevel gear three and bevel gear four, the power is transmitted, and finally the shaft and propeller are driven to operate stably. The entire transmission link is tightly meshed, with low power loss, which can ensure that the propeller can continuously output stable power and adapt to the power requirements of various operating scenarios.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 This utility model proposes a propeller fairing that is easy to install, including a shell 1, a connecting plate 2 fixedly connected to the top of the shell 1, a connecting cover 3 fixedly connected to the top of the connecting plate 2, a connecting cover 4 fixedly connected to the bottom of the shell 1, a motor 5 provided on the outer wall of the connecting cover 3, and an auxiliary mechanism 6 provided inside the connecting cover 3. The auxiliary mechanism 6 includes a bevel gear 61, which is rotatably connected to the inner wall of the connecting cover 3, and is fixedly connected to the output end of the motor 5.

[0020] In this embodiment of the utility model, in order to enable the auxiliary mechanism 6 to operate better, specifically, bevel gear 1 61 meshes with bevel gear 2 62, bevel gear 2 62 is fixedly connected to column 63, column 63 is rotatably connected to the inner wall of outer shell 1, bevel gear 3 64 is fixedly connected below column 63, bevel gear 3 64 meshes with bevel gear 4 65, bevel gear 4 65 is fixedly connected to rotating shaft 66, and rotating shaft 66 is rotatably connected to the inner wall of connecting cover 2 4. There is a propeller 67, and a connecting plate 68 is fixedly connected to the outer wall of the connecting cover 2 4. The connecting plate 68 is provided with an insertion interface 613 and a threaded hole 614. An L-shaped plate 611 is fixedly connected to the connecting plate 68. The side wall of the L-shaped plate 611 is provided with a snap-fit ​​interface 612. The threaded hole 614 is threaded with a bolt 621. An insertion block 619 is inserted into the insertion interface 613. A connecting block 615 is fixedly connected to the insertion block 619. A flow guide 69 is fixedly connected to the side wall of the connecting block 615.

[0021] Furthermore, a movable rod 616 is slidably connected to the side wall of the connecting block 615, and an auxiliary plate 617 is fixedly connected to the movable rod 616. The auxiliary plate 617 and the connecting block 615 are connected by a spring 618. An auxiliary block 620 is fixedly connected to the side wall of the connecting block 615. By pressing the auxiliary plate 617, the insertion block 619 can be aligned with the insertion interface 613 of the connecting plate 68 and inserted. After releasing, the spring 618 causes the movable rod 616 and the auxiliary plate 617 to spring back and engage with the L-shaped plate 611.

[0022] In this invention, during use, the output of motor 5 drives bevel gear 61 to rotate. The rotation of bevel gear 61 drives bevel gear 62 to rotate, which in turn drives the fixedly connected column 63 to rotate. The rotation of column 63 drives bevel gear 64 to rotate, which in turn drives bevel gear 65 to rotate. The rotation of bevel gear 65 drives shaft 66 to rotate, which in turn drives propeller 67 to rotate. When installing the guide shield 69, the auxiliary plate 617 is first pushed inward. Press the button, then align the plug block 619 below the fairing 69 with the plug interface 613 on the connecting plate 68 and plug it in. After plugging in, release the auxiliary plate 617. Under the elastic reset action of the spring 618, the movable rod 616 and the auxiliary plate 617 will spring back, so that the auxiliary plate 617 will be snapped into the snap interface 612 of the L-shaped plate 611, thus completing the initial positioning of the fairing 69. Then, the bolt 621 is installed through the threaded hole 614 and the auxiliary block 620, thus completing the final installation and fixation of the fairing 69.
