Description

Technical Field

[0001] This utility model relates to the field of propeller technology, specifically a variable pitch propeller based on lightweight carbon nylon material. Background Technology

[0002] In many fields such as aviation, marine and industrial fluid transportation, propellers are a key power propulsion component, and their performance directly affects the operating efficiency, energy consumption and stability of the entire system.

[0003] Traditional propellers are mostly made of metal materials, such as aluminum alloys and stainless steel. While these metal materials have a certain strength, they are also heavy, increasing the overall weight of the propeller assembly. During operation, more energy is required to drive the propeller. In addition, metal materials are prone to corrosion and wear in harsh environments, such as humid marine environments or industrial environments containing corrosive media. The pitch of traditional propellers is usually fixed and cannot be adjusted in real time according to the actual working environment and conditions. For example, during the takeoff phase of an aircraft, a large thrust is required to overcome gravity and air resistance. If the pitch is too small, the thrust generated by the propeller will be insufficient, leading to an increased takeoff distance and even affecting flight safety. During the cruise phase, an excessively large pitch will increase the load on the propeller, resulting in increased energy consumption. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a variable-pitch propeller based on lightweight carbon nylon material, which solves the problems of heavy propellers, easy damage, difficult pitch adjustment, and inconvenient maintenance through material, structure, and variable-pitch design.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a variable-pitch propeller based on lightweight carbon nylon material, comprising: a central circle, the central circle including a helical device, the outer wall of the helical device being rotatably connected to the inner wall of the central circle, the central circle further including an adjustment device, the outer wall of the adjustment device being slidably connected to the inner wall of the central circle, the adjustment device driving the helical device to rotate by sliding, the helical device including a rotating rod, a locking block being fixedly connected to the side wall of the rotating rod, and a helical blade being fixedly connected to the inner wall of the locking block by bolts, the helical blade being made of lightweight carbon nylon material.

[0008] Preferably, the outer wall of the rotating rod is rotatably connected to the inner wall of the central circle, and the outer wall of the rotating rod is arranged in a circumferential array along the central axis of the central circle. This structural layout makes the propeller uniformly stressed during rotation, making the operation more stable, effectively reducing the risk of component wear and failure caused by uneven stress, and extending the service life of the propeller.

[0009] Preferably, the adjustment device includes a passive plate, a pull rod rotatably connected to the side wall of the passive plate, and a trapezoidal plug rotatably connected to the end of the pull rod away from the passive plate. The side wall of the passive plate is fixedly connected to the end of the round rod away from the locking block. When the equipment is in operation, the fluid will rush into the chamber opened in the inner wall of the central circle. As the pressure of the fluid in the chamber gradually increases, the trapezoidal plug slides open along the trapezoidal groove under the pressure.

[0010] Preferably, the outer wall of the trapezoidal plug is slidably connected with a trapezoidal groove, which is formed on the inner wall of the central circle.

[0011] Preferably, a compression spring is fixedly connected to the bottom end of the passive plate, and the bottom end of the compression spring is fixedly connected to the inner wall of the central circle. When the pressure in the chamber changes and the trapezoidal plug moves to drive the passive plate, the compression spring can provide a certain buffer and restoring force.

[0012] Preferably, the inner wall of the central circle has a cavity, and a trapezoidal hole is fixedly connected above the central circle located on the trapezoidal groove. The top of the cavity communicates with the outside through the trapezoidal groove.

[0013] (III) Beneficial Effects

[0014] This invention provides a variable-pitch propeller based on lightweight carbon nylon material. It has the following advantages:

[0015] This invention, through the combination of a spiral device and an adjustment device, utilizes lightweight carbon nylon material to manufacture the spiral blade, significantly reducing the overall weight of the propeller. This helps reduce energy consumption during equipment operation. Simultaneously, the carbon nylon material possesses excellent strength and corrosion resistance, enabling the propeller to operate stably and reliably even in harsh environments, effectively resisting wear and corrosion. When the fluid flows into the chamber, the movement of the trapezoidal plug drives the pull rod, which in turn displaces the passive plate, ultimately causing the spiral blade to change angle, achieving an adaptive pitch effect. This allows the propeller to automatically adjust its pitch according to the actual conditions of the fluid. When the pressure inside the chamber changes, the trapezoidal plug's movement causes the passive plate to move, and the compression spring provides a certain amount of buffering and restoring force. The spiral blade is bolted to the rotating rod via a locking block, ensuring the stability of the spiral blade during high-speed rotation, preventing it from loosening and falling off, and facilitating future replacement.

[0022] 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.

[0023] Example

[0024] Please see Figure 1-5 This utility model provides a technical solution: a variable pitch propeller based on lightweight carbon nylon material, comprising:

[0025] The central circle 1 includes a spiral device 2, the outer wall of which is rotatably connected to the inner wall of the central circle 1. The central circle 1 also includes an adjustment device 3, the outer wall of which is slidably connected to the inner wall of the central circle 1. The adjustment device 3 drives the spiral device 2 to rotate by sliding. The central circle 1 comes into contact with the fluid, forming a certain pressure, which causes the adjustment device 3 to change in the inner cavity of the central circle 1, driving the spiral device 2 to rotate, thereby realizing the adaptive pitch function of the spiral device 2 to adapt to different working environments.

[0026] The propeller assembly 2 includes a rotating rod 20, with a locking block 21 fixedly connected to the side wall of the rotating rod 20. A spiral blade 22 is fixedly connected to the inner wall of the locking block 21 by bolts. The spiral blade 22 is made of lightweight carbon nylon. The outer wall of the rotating rod 20 is rotatably connected to the inner wall of the central circle 1. The outer wall of the rotating rod 20 is arranged in a circumferential array along the central axis of the central circle 1. The rotating rod 20 in the propeller assembly 2 rotates due to the rotation of the passive plate 30. During this process, since the locking block 21 is fixedly connected to the side wall of the rotating rod 20, and the spiral blade 22 is fixedly connected to the locking block 21 by bolts, it rotates synchronously with the rotating rod 20, realizing the function of adaptive variable pitch. The spiral blade 22 is made of lightweight carbon nylon, which is lightweight and significantly reduces the overall weight of the propeller. At the same time, it has good strength and corrosion resistance, enabling the propeller to operate stably and reliably in harsh environments and effectively resisting wear and corrosion.

[0027] The adjustment device 3 includes a passive plate 30, a pull rod 31 rotatably connected to the side wall of the passive plate 30, a trapezoidal plug 32 rotatably connected to the end of the pull rod 31 away from the passive plate 30, a fixed connection between the side wall of the passive plate 30 and the end of the round rod away from the locking block 21, and a trapezoidal groove 34 slidably connected to the outer wall of the trapezoidal plug 32. The trapezoidal groove 34 is opened on the inner wall of the central circle 1. As the pressure of the fluid in the chamber 35 gradually increases, the trapezoidal plug 32 opens along the trapezoidal groove 34 on the inner wall of the central circle 1 under the action of pressure. During this process, since the pull rod 31 is rotatably connected to the passive plate 30, the movement of the trapezoidal plug 32 will drive the pull rod 31 to move, thereby causing the passive plate 30 to rotate. The passive plate 30 causes the spiral device 2 to rotate, thereby realizing the spiral adaptive variable pitch function, and can also automatically adjust the pitch according to the actual situation of the fluid.

[0028] A compression spring 33 is fixedly connected to the bottom end of the passive plate 30. The bottom end of the compression spring 33 is fixedly connected to the inner wall of the center circle 1. When the pressure in the chamber 35 decreases or disappears, the compression spring 33 will push the passive plate 30 to reset. The passive plate 30 drives the trapezoidal plug 32 to move in the opposite direction along the inner wall of the trapezoidal groove 34 through the pull rod 31. At the same time, it causes the spiral device 2 to rotate in the opposite direction, so that the spiral device 2 returns to the initial or appropriate angle, in preparation for the next adaptive variable pitch.

[0029] A cavity 35 is provided on the inner wall of the central circle 1. A trapezoidal hole 36 is fixedly connected above the trapezoidal groove 34 of the central circle 1. The top of the cavity 35 is connected to the outside through the trapezoidal groove 34. During the rotation of the central circle 1, it comes into contact with the external fluid, and the external fluid enters the cavity 35 inside the central circle 1 through the trapezoidal hole 36.

[0030] When in use, the central circle 1 comes into contact with the fluid, creating a certain pressure, which causes the adjustment device 3 to change within the cavity of the central circle 1, driving the screw device 2 to rotate, thus realizing the adaptive pitch function of the screw device 2 to adapt to different working environments.

[0031] When the equipment starts running, the central circle 1 rotates and comes into contact with the external fluid. The external fluid enters the chamber 35 inside the central circle 1 through the trapezoidal hole 36. As the pressure of the fluid in the chamber 35 gradually increases, the trapezoidal plug 32 opens along the trapezoidal groove 34 on the inner wall of the central circle 1 under the pressure. During this process, since the pull rod 31 is rotatably connected to the passive plate 30, the movement of the trapezoidal plug 32 will drive the pull rod 31 to move, which in turn causes the passive plate 30 to rotate. The passive plate 30 causes the screw device 2 to rotate, thereby realizing the function of adaptive variable pitch of the screw. At the same time, it can also automatically adjust the pitch according to the actual situation of the fluid.

[0032] When the pressure inside chamber 35 decreases or disappears, the compression spring 33 pushes the passive plate 30 to reset. The passive plate 30 drives the trapezoidal plug 32 to move in the opposite direction along the inner wall of the trapezoidal groove 34 via the pull rod 31, and at the same time causes the screw device 2 to rotate in the opposite direction, so that the screw device 2 returns to the initial or appropriate angle, in preparation for the next adaptive variable pitch.

[0033] When the adjusting device 3 moves due to the pressure of the fluid, the rotating rod 20 in the propeller device 2 rotates due to the rotation of the passive plate 30. During this process, since the side wall of the rotating rod 20 is fixedly connected to the locking block 21, and the locking block 21 is fixedly connected to the propeller blade 22 by bolts, it rotates synchronously with the rotating rod 20 to realize the function of adaptive variable pitch. The propeller blade 22 is made of lightweight carbon nylon material. This material is lightweight, which significantly reduces the overall weight of the propeller. At the same time, it has good strength and corrosion resistance, which enables the propeller to operate stably and reliably in harsh environments and effectively resists wear and corrosion.

[0034] When the propeller blade 22 needs to be replaced, simply loosen the bolts between the propeller locking block 21 and the inner wall of the propeller blade 22, and the new propeller blade 22 can be installed.
