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.

[0037] 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. Example 1

[0038] like Figure 1-6 As shown, the adaptive wind force regulating ventilation valve for building construction includes a wind wheel 21, a rotating connecting seat 2 and an adaptive air volume regulating device.

[0039] The wind wheel 21 and the upper end of the rotating connecting seat 2 are detachably connected; the adaptive wind volume adjustment device includes a driving wheel 4, a needle-pendulum transmission rail, a transmission wheel 10, a conical transmission wheel 13, a fixed rod 11 and a wind control plate assembly; the side end of the rotating connecting seat 2 is provided with a meshing tooth portion 5 adapted to mesh with the driving wheel 4, one end of the needle-pendulum transmission rail is transmission-connected to the driving wheel 4, and the other end is transmission-connected to the transmission wheel 10, the two ends of the fixed rod 11 are respectively fixed to the transmission wheel 10 and the conical transmission wheel 13, and the conical transmission wheel 13 is transmission-connected to the wind control plate assembly.

[0040] The needle pendulum transmission rail includes a linear slide rail portion 3 and an arcuate slide rail portion 9. A guide column 7 is eccentrically provided on the driving wheel 4. A slide groove adapted for sliding the guide column 7 is provided on the linear slide rail portion 3. The arcuate slide rail portion 9 is provided with an arcuate rack, which is meshed and transmission-connected with the transmission wheel 10.

[0041] The wind control plate assembly includes a fixed seat 25, a wind control plate 6, a support ring 17, a connecting piece 15, a conical wheel 20, a connecting rod 19, a rotating collar 18 and a lower arc-shaped synchronous rod 16; one end of the wind control plate 6 is rotatably connected to the side wall of the fixed seat 25, and the other end is rotatably connected to the inner side of the support ring 17 through a rotating shaft, one end of the connecting piece 15 is fixed to the rotating shaft, and the other end is rotatably connected to the lower arc-shaped synchronous rod 16, and the upper end of the fixed seat 25 is rotatably connected to the rotating connecting seat 2. The number of connecting pieces 15 is multiple and corresponds to the number of wind control plates 6, and the multiple connecting pieces 15 are rotatably connected to the lower arc-shaped synchronous rod 16 at one end away from the rotating shaft, and the two ends of the upper arc-shaped synchronous rod 14 are rotatably connected to the middle of two adjacent connecting pieces 15. At the same time, the rotating ring 18 is fixed to the side end of the support ring 17, and the rotating shaft is rotatably arranged in the rotating ring 18. One end of the connecting rod 19 is fixed to the connecting piece 15, and the other end is fixed to the conical wheel 20. The conical wheel 20 and the conical transmission wheel 13 are meshed and connected.

[0042] The internal components and working principle of the adaptive air volume adjustment device are as follows:

[0043] See also Figure 3-Figure 5 When the wind wheel 21 is driven by wind to rotate, it will drive the rotating connecting seat 2 to rotate. During the rotation of the rotating connecting seat 2, it will drive the driving wheel 4 engaged with it to rotate. When the driving wheel 4 is rotating, since the guide column 7 is eccentrically fixed at its upper end, the eccentric movement of the guide column 7 will drive the linear slide part 3 to swing left and right (that is, while the guide column 7 slides in the slide groove of the linear slide part 3, it will drive the linear slide part 3 to swing left and right). When the linear slide part 3 swings left and right, it will drive the transmission wheel 10 engaged with it to rotate slightly. The transmission wheel 10 drives the conical transmission wheel 13 to rotate through the synchronous rotation of the fixed rod 11, and then the connecting rod 19 drives the rotating shaft to rotate (with Figure 6 as shown).

[0044] Since the rotating shaft is fixed to the wind control plate 6, the wind control plate 6 can be driven to swing left and right. During the swinging process, the wind control plate 6 will reveal a gap for air to pass through according to the swing amplitude. When the external wind force is strong, the frequency of the swinging of the wind control plate 6 will increase (for example, opening and closing), thereby reducing the strong wind pressure and preventing the strong wind from entering the room head-on and causing damage.

[0045] In the above process, the frequency and amplitude of the left and right swing of the wind control plate 6 are autonomously regulated according to the external wind force. In specific applications, it can be used in combination with opening windows to achieve indoor ventilation adjustment in a windless environment or a strong wind environment.

[0046] like Figure 3 As shown, the wind wheel 21 is fixed on the wind wheel sleeve shaft 200, and a fixing screw 1 is provided at the upper end of the rotating connecting seat 2, and the wind wheel sleeve shaft 200 and the fixing screw 1 are screwed and fixed.

[0047] The wind wheel sleeve shaft 200 and the fixing screw 1 are detachably fixed, which is convenient for disassembly and maintenance of the adaptive air volume adjustment device.

[0048] like Figure 5 As shown, the adaptive air volume regulating device also includes a connecting plate 12 and a positioning rod 8. The connecting plate 12 is fixed to the side end of the fixing seat 25. One end of the positioning rod 8 is fixed to the connecting plate 12, and the other end is rotatably connected to the needle pendulum transmission rail.

[0049] In this embodiment, the adaptive wind control ventilation valve for a building also includes a shell 22, a through hole adapted for the rotation connection seat 2 to pass through is provided in the middle of the shell 22, and a positioning ring for placing the shell 22 is provided at the side end of the rotation connection seat 2.

[0050] like Figure 3 As shown, a connecting air duct 23 is provided at the lower end of the fixing seat 25 , and a threaded ring which is screwed and fixed to the connecting air duct 23 is provided at the middle of the air outlet duct 24 . Example 2

[0051] This embodiment is aimed at Figure 4 and Figure 5 The transmission mode of the needle swing transmission rail is described in detail:

[0052] For the entire transmission process, please refer to Figure 8-Figure 9 As shown:

[0053] exist Figure 8 The middle guide column 7 is located at the lowermost end of the driving wheel 4 .

[0054] by Fig. 9 As shown, when the driving wheel 4 rotates counterclockwise, the position of the guide column 7 changes, and at this time, the arc-shaped slide rail portion 9 rotates slightly.

[0055] by Fig.10 As shown in FIG. 1 , when the driving wheel 4 rotates counterclockwise, the position of the guide column 7 changes, and the arc-shaped slide rail portion 9 changes the direction of rotation until the driving wheel 4 continues to rotate counterclockwise to Figure 8 status.

[0056] Therefore, through the above transmission structure, it is possible to control the transmission wheel 10 to rotate reciprocatingly and periodically. Example 3

[0057] This embodiment mainly describes in detail the application scenario of the adaptive wind force control ventilation valve. Figure 7 For example, the adaptive wind control ventilation valve can be arranged on the top of the house. The windows of the house can be used as horizontal ventilation facilities, while the adaptive wind control ventilation valve is a vertical ventilation facility, which is mainly used for indoor ventilation when the windows are closed in windy weather.
