Description

Technical Field

[0001] This utility model relates to the field of power cooling tower technology, and in particular to an adjustable louver device and a cooling tower. Background Technology

[0002] To improve the cooling efficiency of power cooling towers, louvers are typically installed. These louvers enhance heat dissipation, prevent debris from entering the tower, and protect against cold air impacts in winter, ensuring normal operation. Currently, cooling tower louvers are fixed. While fixed louvers are inexpensive and durable, they have limited adaptability to extreme weather conditions.

[0003] A related technology provides an adjustment mechanism for louvers in a cooling tower, including a window frame mounted on the cooling tower and multiple louvers rotatably connected to the window frame. Lifting rods and support rods are mounted on the window frame. The lifting rods are located on both sides of the window frame and are slidably connected to the window frame. Each lifting rod has multiple linearly and evenly distributed support rods, each of which is fixedly connected to the lifting rod. The louvers are positioned between the support rods. A connecting plate is positioned between two lifting rods and is fixedly connected to the lifting rod. A drive mechanism mounted on the outer wall of the cooling tower is also connected to the connecting plate. The drive mechanism can drive multiple louvers to rotate synchronously to adjust the angle of the louvers. However, when the louvers are subjected to external impacts or repeated impacts, the louvers may collide with the support rods, causing damage to the contact area between the louvers and the support rods, reducing the reliability and lifespan of the louvers.

[0023] The beneficial effects of this utility model are:

[0024] The present invention provides an adjustable louver device and a cooling tower. The adjustable louver device is used to adjust the angle of the louvers and includes a louver assembly, a buffer assembly, and a drive assembly. The louver assembly includes a window frame, which is fixedly connected to the cooling tower body. Multiple louvers are rotatably connected to the window frame. The buffer assembly includes a connector and at least one elastic buffer. The connector is fixedly connected to the pivot of the multiple louvers.

[0025] When adjusting the angle of the louvers, the adjustable louver device provides power through the drive component, and achieves synchronous movement of multiple louvers with the help of connectors. The power is transmitted by elastic buffers or connectors. When the louvers are subjected to external impact, the elastic buffers absorb part of the impact energy through their own elastic deformation, thereby buffering the direct impact force on the louvers and connectors. This avoids damage to the connectors or plastic deformation of the louvers due to excessive instantaneous impact force. In addition to transmitting power, the connectors work with the buffers of the elastic buffers to reduce the transmission of impact between multiple synchronously moving louvers, preventing the louvers from causing uncoordinated displacement or structural damage due to impact, thus ensuring the overall stability and service life of the adjustable louver device.

[0037] This embodiment provides an adjustable louver device for adjusting the angle of the louver 12, such as... Figure 1 and Figure 2 As shown, the adjustable louver device includes a louver assembly 1, a buffer assembly 2, and a drive assembly 3. The louver assembly 1 includes a window frame 11, which is fixedly connected to the cooling tower body 20. Multiple window blades 12 are rotatably connected to the window frame 11. The buffer assembly 2 includes a connector 21 and at least one elastic buffer 22. The connector 21 is fixedly connected to the rotating shaft of the multiple window blades 12. Along the first direction, at least one elastic buffer 22 is fixedly connected to one end of the connector 21. The elastic buffer 22 can be fixedly connected to the cooling tower body 20. The fixed end of the drive assembly 3 is fixedly connected to the cooling tower body 20, and the output end of the drive assembly 3 is drively connected to the other end of the elastic buffer 22 or the connector 21.

[0038] When adjusting the angle of the window slats 12, the adjustable louver device is powered by the drive assembly 3. The synchronous movement of multiple window slats 12 is achieved through the connector 21. Power is transmitted using the elastic buffer 22 or the connector 21. When a window slat 12 is subjected to external impact, the elastic buffer 22 absorbs some of the impact energy through its elastic deformation, thus buffering the direct impact on the window slats 12 and the connector 21. This prevents damage to the connector 21 or plastic deformation of the window slats 12 due to excessive instantaneous impact force. The connector 21, in addition to transmitting power, works in conjunction with the buffering effect of the elastic buffer 22 to reduce the transmission of impact among the multiple synchronously moving window slats 12, preventing uncoordinated displacement or structural damage to the window slats 12 due to impact, thereby ensuring the overall stability and service life of the adjustable louver device. It should be noted that in this embodiment, the elastic buffer 22 is snap-fitted to one end of the connector 21. In other embodiments, the elastic buffer 22 is welded or bonded to one end of the connector 21, etc. No limitations are imposed here.

[0039] Optionally, in this embodiment, the window 12 has a cavity inside. The cavity in the window 12 makes it lighter, reduces manufacturing costs, and decreases resistance when opening and closing. In other embodiments, the window 12 may also be solid, etc. No limitation is made here.

[0040] Optionally, the outer surface of the window 12 is coated with an anti-corrosion coating. Since the window 12 is exposed to the external environment for a long time, the anti-corrosion coating can better protect the window 12, extend its service life, and prevent the window 12 from discoloring or peeling off due to corrosion, thus ensuring the aesthetics and structural integrity of the window 12.

[0041] Optionally, in this embodiment, the connector 21 is made of aluminum alloy. Aluminum alloy has low density, good corrosion resistance, and high strength. In other embodiments, the connector 21 may also be made of stainless steel or the like. No limitation is imposed here.

[0042] Specifically, in this embodiment, the connector 21 is a connecting rod. In other embodiments, the connector 21 may also be a connecting plate or a connecting block, etc. No limitations are imposed here.

[0043] Specifically, in this embodiment, the elastic buffer 22 is a spring. In other embodiments, the elastic buffer 22 can also be a leaf spring, a spring-rubber composite, or a gas spring, etc. No limitation is imposed here.

[0044] Optionally, in this implementation, such as Figure 1 and Figure 2As shown, the buffer assembly 2 includes a connector 21 and an elastic buffer 22 fixedly connected to one end of the connector 21. The elastic buffer 22 is fixedly connected to the cooling tower body 20, and the output end of the drive assembly 3 is drively connected to the other end of the connector 21. When the angle of the window 12 is adjusted, the drive assembly 3 operates, and power is transmitted to the elastic buffer 22 through the output end, so that the angle of the window 12 is adjusted. After the window 12 is adjusted, when the window 12 is subjected to external impact, the elastic buffer 22 will undergo elastic deformation, thereby absorbing the external impact and preventing the external impact from damaging the window 12. In some other embodiments, the buffer assembly 2 includes a connector 21 and an elastic buffer 22. Along the first direction, the elastic buffer 22 is fixedly connected to the lower end of the connector 21, and the output end of the drive assembly 3 is drively connected to the connector 21. No limitation is made here.

[0045] Optionally, in other embodiments, the buffer assembly 2 may further include a connector 21 and two elastic buffers 22. Along the first direction, the two elastic buffers 22 are fixedly connected to both ends of the connector 21, with one elastic buffer 22 fixedly connected to the cooling tower body 20, and the output end of the drive assembly 3 being drive-connected to the other elastic buffer 22. With elastic buffers 22 fixedly connected to both ends of the connector 21, when the angle of the window 12 is adjusted, the elastic buffer 22 drive-connected to the output end of the drive assembly 3 transmits power to the multiple window 12s, compressing the other elastic buffer 22. After the window 12 is adjusted, when the window 12 is subjected to an external impact, the compressed elastic buffer 22 is stretched, and the other is compressed through the elastic buffer 22; or the compressed elastic buffer 22 continues to be compressed, and the other continues to be stretched through the elastic buffer 22. Both elastic buffers 22 simultaneously undergo elastic deformation to absorb impact energy and buffer power fluctuations. The two together cancel out the impact force, avoiding rigid collisions.

[0046] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, the drive assembly 3 includes a drive member 31, a gear 32, and a rack 33. The fixed end of the drive member 31 is fixedly connected to the cooling tower body 20. The gear 32 is coaxially sleeved on the output end of the drive member 31, and the gear 32 rotates synchronously with the drive member 31. The rack 33 extends along a first direction and meshes with the gear 32. The rack 33 is fixedly connected to the elastic buffer 22 or the connecting member 21. When adjusting the angle of the window 12, the drive member 31 rotates, driving the gear 32, which is coaxially sleeved on the output end of the drive member 31, to rotate. Since the rack 33 and the gear 32 are meshed, the rack 33 reciprocates along the first direction, simultaneously driving the elastic buffer 22 or the connecting member 21, so as to achieve synchronous adjustment of the angles of multiple window 12s. In other embodiments, the drive assembly 3 includes a mounting base and a linear motor. The mounting base is fixedly connected to the cooling tower body 20, and the linear motor is fixedly connected to the mounting base. The output end of the linear motor is fixedly connected to the connecting member 21 or the elastic buffer 22, etc. No limitation is made here.

[0047] It should be noted that in this embodiment, the rack 33 is fixedly connected to the connector 21. In other embodiments, the rack 33 may also be fixedly connected to the elastic buffer 22, etc. No limitations are imposed here.

[0048] Specifically, in this embodiment, the driving component 31 is a rotary handle. In other embodiments, the driving component 31 may also be a drive handwheel, a rotary motor, or a rotary cylinder, etc. No limitation is imposed here.

[0049] Optionally, the cooling tower body 20 is provided with multiple positioning holes, the drive component 31 has a limit hole, and the drive assembly 3 also includes a limit pin, which can be inserted into the limit hole and any one of the positioning holes. After the angle of the window 12 is adjusted, the limit pin can be inserted into the limit hole and any corresponding positioning hole, so that the drive component 31 stops rotating. The mechanical limiting effect of the limit pin restricts the relative rotation between the drive component 31 and the cooling tower body 20, thereby locking the drive component 31 and ensuring that the angle of the window 12 remains stable. It should be noted that the limit hole is located on the outermost side of the rotating handle along the extension direction of the handle.

[0050] This embodiment also provides a cooling tower, including a cooling tower body 20 and an adjustable louver device, the adjustable louver device being disposed on the cooling tower body 20. By applying this adjustable louver device, the elastic buffer 22 can absorb the impact force received by the window 12, reducing the transmission of impact among multiple synchronously moving window 12s, preventing the window 12 from causing uncoordinated displacement or structural damage due to impact, thereby improving the service life of the window 12.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
