Description

Technical Field

[0001] The present application relates to the technical field of transmission devices, and in particular to a building wind power transmission device. Background Art

[0002] Transmission equipment is an important part of the mechanical system, mainly used to transmit power and motion. For the method of rotational transmission, for example, Chinese invention patent CN2024119897402 discloses a gear transmission device for rotating amusement facilities, which mainly records the solution of uniform distribution of the rotational transmission drive position. At the same time, Chinese invention patent CN202411899321X discloses a transmission device and a pan-tilt camera, which mainly records the solution of adjusting the angle of the lens module.

[0003] During the wind capture transmission process, the wind is unstable and sometimes strong and sometimes weak, and the wind direction is not fixed, which can easily cause the central axis transmission process to be affected by strong force and affect the rotation, or cause the mechanical structure of the central axis to be damaged. Therefore, even if the drive position is evenly distributed and the active drive angle can be changed, the adaptability of the wind capture process is still very poor. Summary of the invention

[0004] The present invention provides a building wind power transmission device, which can adaptively change the windward surface of a wind blade according to the wind direction, thereby preventing strong wind from affecting the rotation effect of a transmission center shaft and the stability of a mechanical structure.

[0006] Among them, the advantage of the adaptive angle offset mechanism is that it can change the angle of the transmission blade according to the wind direction and wind force, thereby preventing the blades from being subjected to wind forces from multiple directions and affecting the rotation of the transmission shaft and the mechanical structure.

[0008] Among them, the advantage of the buffer component is that when the transmission blades are hit by strong winds, the buffering and shock-absorbing effects of the shock-absorbing springs and shock-absorbing blocks can offset the strong wind force and protect the structure of the transmission device from being damaged by strong winds.

[0009] Preferably, the adaptive angle offset mechanism further comprises a base plate and a rotating disk, the lower end of the rotating seat and the rotating disk are fixed, the rotating disk is rotatably mounted on the base plate, and the fixed block is fixed to the upper end of the base plate.

[0014] Among them, the function of the one-way rotating component is to maximize the energy utilization rate. If it can rotate in both directions, it will easily lead to the loss of wind energy during the transmission process.

DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present application.

[0023] It should be clear that the embodiments described below are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by technicians in the relevant field without making creative work are within the scope of protection of the present application.

[0024] Embodiment 1: This embodiment describes in detail the scheme of the building wind power transmission device: like Figure 1-Figure 5 As shown, a building wind power transmission device includes a transmission shaft 6, a transmission blade 12 and an adaptive angle offset mechanism; The adaptive angle offset mechanism includes a connecting rod 19, a steering end 8, a rotating rod 14, a bottom plate 17, a rotating disk 16 and a buffer assembly; one end of the rotating rod 14 is fixed to the transmission blade 12, and the other end is fixed to the steering end 8; the connecting rod 19 is vertically fixed to the end of the transmission shaft 6, and both ends of the connecting rod 19 are provided with a transmission end 9, and accordingly, the steering end 8 is provided with an arc groove adapted to the movement path of the transmission end 9. The lower end of the rotating seat 15 is fixed to the rotating disk 16, and the rotating disk 16 is rotatably mounted on the bottom plate 17, and the fixing block 10 is fixed to the upper end of the bottom plate 17.

[0025] Among them, the buffer assembly includes a fixed block 10, a shock-absorbing block 11, a shock-absorbing spring and a rotating seat 15; a connecting piece is fixedly provided on the fixed block 10, and the number of connecting pieces is two. The shock-absorbing block 11 and the connecting piece are connected by a shock-absorbing spring; the rotating seat 15 is rotatably connected to the rotating rod 14, and an impact block 13 is provided at the side end of the rotating seat 15, and the shock-absorbing block 11 is located on the rotational movement path of the impact block 13.

[0026] The connection relationship and working principle between the components of the adaptive angle offset mechanism are as follows: When the transmission blades 12 are driven by wind, they can rotate. Since the transmission end 9 and the steering end 8 are rotatable and slidable, the steering end 8 can drive the transmission end 9 to rotate in the circumferential direction during the circumferential rotation, and is not restricted by the horizontal rotation of the steering end 8 itself ( Figure 3 As shown, the connection point between the connecting rod 19 and the transmission shaft 6 is located exactly in the center of the steering end 8).

[0027] The connection relationship and working principle of the components of the buffer assembly are as follows: The spring and the damping block of the buffer assembly reduce the impact of sudden wind force on the transmission shaft and extend the life of the equipment. Specifically, the impact block 13 contacts the damping block 11 when subjected to force, and releases the force after the deformation of the spring is buffered.

[0028] Embodiment 2: The wind power transmission device of the building also includes a power storage and retransmission mechanism; the power storage and retransmission assembly includes a slide rail 30, a slider segment 26, an elastic spring 27, a transmission tooth block 29, a transmission wheel 18, a U-shaped limit block 28, a positioning column and a one-way rotation assembly; the slider segment 26 (the actual length of the slider segment 26 is not as long as shown in the figure, and the figure is only for reference) is slidably installed on the slide rail 30, one end of the elastic spring 27 is fixed to the slider segment 26, and the other end is fixed to the transmission tooth block 29, one end of the U-shaped limit block 28 is fixed to the side end of the slider segment 26, and the other end is in contact with the outer section of the transmission tooth block 29; the transmission wheel 18 and the slider segment 26 are meshed and connected in transmission, and the one-way rotation assembly is connected in transmission with the transmission wheel 18. The end of the slider segment 26 is provided with a through hole adapted to the sliding of the positioning column, and the transmission tooth block 29 is fixed to the end of the positioning column.

[0029] Among them, the one-way rotation component includes a hollow auxiliary wheel 4, a slide rail 21, a telescopic spring 22 and a slider 23; the slide rail 21 is fixed to the side end of the transmission shaft 6, the slider 23 is slidably installed in the slide rail 21, one end of the telescopic spring 22 is fixed to the slider 23, and the other end is fixed to the groove wall on the slide rail 21; a ratchet 25 is provided at the inner end of the auxiliary wheel 4, and the slider 23 is provided with a one-way transmission block 24, the one-way transmission block 24 and the ratchet 25 are one-way transmission, and the auxiliary wheel 4 and the transmission wheel 18 are meshed and transmission connected.

[0030] The connection relationship and working principle of the components of the power storage and retransmission mechanism are as follows: The power storage and retransmission mechanism uses elastic potential energy storage and one-way transmission mechanism to ensure the continuity of power generation. Figure 3 and Figure 5 As shown, when the transmission shaft 6 rotates, it can directly drive the generator connected to it to work. When the transmission shaft 6 drives the auxiliary drive wheel 4 to rotate through the one-way rotation component, it can drive the transmission wheel 18 to rotate, thereby driving the slider segment 26 to slide. When the slider segment 26 slides, it compresses or stretches the reset spring ( Figure 3 and Figure 5 Not shown, one end of the return spring is fixed to the inner end of the slide rail, and the other end is fixed to the transmission gear block 29).

[0031] When the driving wheel 18 drives the slider section 26 to slide to the side end, as shown in FIG. Figure 5As shown, the transmission wheel 18 will mesh with the transmission tooth block 29, but because the transmission tooth block 29 and the slider segment 26 are elastically connected by the elastic spring 27, when the transmission tooth block 29 is pushed to the next tooth position by the transmission wheel 18, it is reset by elastic force, so that the transmission tooth block 29 returns to its original position and meshes with the next tooth position of the transmission wheel 18 again. Therefore, the effect obtained at this time is that the transmission wheel 18 has accumulated power to the limit and is in an idling state. When the wind force decreases or the transmission shaft moves in the reverse direction, the slider segment 26 will drive the transmission wheel 18 to rotate when it is reset due to the pulling force of the reset spring, and then drive the auxiliary wheel 4 to move in the reverse direction again, thereby providing the transmission shaft 6 with additional rotation output power.

[0032] The working principle of the one-way rotating assembly is: like Figure 4 As shown, the transmission shaft 6 can drive the auxiliary wheel 4 to rotate together with it when it rotates counterclockwise, while the transmission shaft 6 will not drive the auxiliary wheel 4 to rotate when it rotates clockwise. The purpose of the one-way drive rotation is to store force only in a specific direction of the transmission shaft 6, so as to avoid the transmission shaft 6 from constantly storing force when rotating, which will weaken the rotation force of the transmission shaft 6 and reduce energy waste.

[0033] This embodiment further comprises a fixing frame 3 and a rotating bearing 2, a transmission shaft 6 and the rotating bearing 2 are rotatably connected, and the rotating bearing 2 is fixed to the fixing frame 3 via a rod.

[0034] In this embodiment, the end of the transmission shaft 6 facing away from the transmission blades 12 may be connected to a generator.

[0035] In this embodiment, limiting rings are provided on both side edges of the auxiliary driving wheel 4, and the transmission wheel 18 is located between the two limiting rings.
