Description

Technical Field

[0001] The invention relates to the technical field of propellers, and in particular to a novel blade and tail wing angle rotation device. Background Art

[0002] Currently, a propeller is a device that converts any form of energy into mechanical energy. Thrust is generated by rotating blades or jets (of water). It can be used to drive a vehicle forward, or as a source of power for other devices such as generators. The origin of propellers began to be associated with Archimedes, who used a screw to raise water for irrigation and rescue boats, so famous that it was called an Archimedean screw. It is possible that the spiral motion in space (the spiral was a special application of Archimedes) was used for irrigation by the Egyptians for centuries. Leonardo da Vinci used this principle to drive his theoretical helicopter, the sketch of which involved a large canvas screw head. The twisted airfoil shape of the modern aircraft propeller was pioneered by the Wright brothers. Although some earlier engineers tried to model air propellers on marine propellers, the Wright brothers realized that propellers were basically the same as wings, and were able to use data on wings from their earlier wind tunnel experiments. They also introduced a twist along the length of the blade. This was necessary to ensure that the angle of attack of the blade remained relatively constant along its length. Their initial propeller blades were only about 5% less efficient than their modern equivalents, which were available about 100 years later. The understanding of slow-speed propeller aerodynamics was fairly complete by the 1920s, but later requirements for smaller diameters to handle more power have compounded the problem.

[0003] The existing new blade and tail angle rotation device has the following problems: some existing blades and tail wings used in propellers are difficult to adjust flexibly and effectively, especially in the lateral design of the tail wing, it is impossible to simply and effectively achieve a steering effect at a certain angle, resulting in defects in the operation of the device, and the existing patents are not easy to solve such problems. Therefore, a new blade and tail angle rotation device is urgently needed to solve the above problems. Summary of the invention

[0004] Based on the technical problem that the existing novel blade and tail wing angle rotation device cannot simply and effectively achieve a certain angle steering effect in the lateral design of the tail wing, the present invention proposes a novel blade and tail wing angle rotation device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A novel blade and tail wing angle rotation device comprises a base plate, a mounting frame is fixedly connected to the top outer wall of the base plate, a fixing seat is fixedly connected to one side of the top outer wall of the mounting frame, a support rod is connected to the top outer wall of the fixing seat through a hinge, a cross wing is fixedly connected to the top end of the support rod, an arc-shaped slide groove is opened on the top outer wall of the cross wing, an arc-shaped slide block is slidably connected to the inner wall of the arc-shaped slide groove, a fixing rod is fixedly connected to one side of the top outer wall of the support rod, an air guide plate is sleeved on the outer wall of the fixing rod near the top, a transfer rod is fixedly connected to one side of the bottom outer wall of the air guide plate, and the bottom end of the transfer rod is fixedly connected to an arc-shaped slide block The top of the block is fixedly connected with soft steel wires on both side outer walls of the arc-shaped sliding block, four mounting plates are fixedly connected on one side outer wall of the fixing seat, a fixed pulley is fixedly connected on the outer walls on the opposite sides of the two mounting plates, an adjusting frame is fixedly connected on one side outer wall of the mounting frame, two adjusting grooves are opened on one side outer wall of the adjusting frame, fixed shafts are fixedly connected on both side outer walls of the mounting frame, sliding sleeves are sleeved on the outer walls of the two fixed shafts, and adjusting rods are fixedly connected on one side outer walls of the two sliding sleeves, the adjusting rod is adapted to the adjusting groove, and one end of the soft steel wire passes around the fixed pulley and is fixedly connected to one side outer wall of the adjusting rod.

[0007] As a further solution of the present invention: a fixing plate is fixedly connected to the top outer wall of the mounting frame, a second motor is fixedly connected to the outer wall of one side of the fixing plate, one end of the output shaft of the second motor is keyed to a rotating shaft, and one end of the rotating shaft is fixedly connected to a fan blade.

[0008] As a further solution of the present invention: a mounting groove is formed on one side of the outer wall at the top of the mounting frame, and the inner walls on both sides of the mounting groove are connected to the same threaded rod through bearings.

[0009] As a further solution of the present invention: the first motor is fixedly connected to the outer wall of one side of the mounting frame, and one end of the output shaft of the first motor is keyed to one end of the threaded rod.

[0010] As a further solution of the present invention: a threaded block is threadedly connected to the outer wall of the threaded rod, the top of the threaded block is connected to a connecting rod via a hinge, and one end of the connecting rod is hinged to the outer wall of one side of the support rod.

[0011] As a further solution of the present invention: bolts are provided at the four corners of the outer wall of the top of the base plate.

[0012] As a further solution of the present invention: one end of the two adjusting rods is fixedly connected with a handle.

[0013] As a further solution of the present invention: shock-absorbing pads are fixedly connected to the four corners of the outer wall at the bottom of the base plate.

[0014] The beneficial effects of the present invention are:

[0015] 1. By setting the cross wing, soft steel wire and adjustment frame, the second motor drives the fan blade to rotate, and the fan blade blows wind backward to use the reverse force for propulsion. The cross wing connected to the fixed seat can change the longitudinal propulsion position of the device in conjunction with the blowing wind force. The first motor drives the threaded rod to rotate, and the threaded block on the outer wall of the threaded rod drives the connecting rod to move, thereby adjusting the angle of the cross wing. One end of the adjusting rod connected by the sliding sleeve on the outer wall of both sides of the mounting frame is adapted to the adjusting groove. One end of the soft steel wire is fixed on the arc-shaped slider, and the other end is fixedly connected to the outer wall of the adjusting rod. By adjusting the different gears of the adjusting rod in the adjusting groove, the adjustment of different lateral angles of the wind guide plate is realized, thereby easily changing the lateral steering of the device to be propelled;

[0016] 2. By setting the adjustment slot and the handle, the adjustment slot is divided into different gears, from high to low, and the deviation angle of the air guide plate can be changed from small to large with the adjustment rod, and then the deflection of the air guide plate can be simply operated through the two adjustment rods. The handle set at one end of the adjustment rod has a soft texture and also has a large friction force, which can make the adjustment more stable;

[0017] 3. By setting the shock-absorbing pad, the fan blade installed on one side of the fixed plate will cause the device to shake when it rotates. After the bolts on the bottom plate are fixed to the device to be propelled, it is very likely that the fixing position is not flat enough, causing the device to shake after it starts working. The set shock-absorbing pad can play a good buffering role between the bottom plate and the fixing device, making the propulsion device more stable, thereby facilitating a series of subsequent adjustment work.
