[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figure 1-Figure 7 As shown, the flow guiding device for the outside of the air cooling tower according to the embodiment of the present invention comprises an annular guide rail 1 and a plurality of flow guiding members 2 .

[0035] The annular guide rail 1 is arranged around the air cooling tower 100 along the circumference of the air cooling tower 100. A plurality of guide members 2 are connected to the annular guide rail 1, and the guide members 2 are movable along the extension direction of the annular guide rail 1. The guide members 2 include a mounting frame 21 and a roller shutter curtain 22. The roller shutter curtain 22 is connected to the mounting frame 21. The mounting frame 21 is rotatable around a first axial direction, and the first axial direction is parallel to the height direction of the mounting frame 21 (e.g., Figure 3 In the up and down direction in the figure), the guide member 2 has a first state and a second state. In the first state, the shutter curtain 22 is used to block the installation frame 21; in the second state, the shutter curtain 22 is spaced apart from the installation frame 21.

[0036] Specifically, Figure 1-Figure 4 As shown, the annular guide rail 1 is in a circular shape and is arranged adjacent to the air cooling tower 100 along the circumference of the air cooling tower 100 so that the guide member 2 is installed on the annular guide rail 1 and can adjust the wind direction and wind speed blowing toward the air cooling tower 100 by changing its position and its own deflection angle.

[0037] It can be understood that the guide member 2 is installed on the annular guide rail 1, and the plurality of guide members 2 can be movable on the annular guide rail 1, so that the plurality of guide members 2 can be properly arranged in the circumferential direction of the air cooling tower 100 in different use environments. Figure 1 As shown, a plurality of flow guides 2 can be evenly arranged in the circumferential direction of the air cooling tower 100; or, as shown in FIG. Figure 2 As shown, a plurality of flow guides 2 can be arranged on one side of the air cooling tower 100. Of course, the plurality of flow guides 2 can also be arranged in a manner of uneven spacing. In addition, the flow through the flow guide 2 can be controlled by changing the opening and closing degree of the rolling shutter curtain 22 (i.e., controlling the spacing between the rolling shutter curtain 22 and the mounting frame in the second state).

[0038] That is, when the ambient wind affects the cooling performance of the air cooling tower 100, the guide member 2 can adjust the state of the guide member 2 according to the wind direction and wind speed to optimize the air flow and reduce the negative impact of the wind on the cooling effect.

[0039] It should be noted that the guide member 2 can be connected to the annular guide rail 1 through an electric slide or a platform driven by a motor, so as to drive the guide member 2 to move on the annular guide rail 1. In addition, the mounting frame 21 can be driven by an electric motor, a drive motor, and a transmission mechanism driven by a motor, so that the mounting frame 21 can rotate.

[0040] In other words, the flow guide device for the outside of the air-cooling tower according to the embodiment of the present invention can set multiple flow guide members 2 at different positions on the annular guide rail 1 according to different wind directions, and can also adjust the angle between the rolling shutter curtain 22 and the wind direction by rotating the mounting frame 21, so as to guide the circumferential flow of air of the air-cooling tower 100, reduce the influence of external wind on the cooling effect of the air-cooling tower 100 in different seasons or environments, and ensure the safe operation of the air-cooling tower 100 unit.

[0041] In some embodiments, the flow guide device for the outside of the air cooling tower of the embodiment of the present invention also includes a first driving member 3, the first driving member 3 includes a first driving part and a first mounting part, the first mounting part is connected to the mounting frame 21, the first driving part is connected to the annular guide rail 1, and the first driving part is used to drive the first mounting part to move along the extension direction of the annular guide rail 1.

[0042] It is understandable that if Figure 1-Figure 4 As shown, the first driving part is a power component for driving the first mounting part to move along the extension direction of the annular guide rail 1. The first driving part may include one or more motors (such as a stepper motor, a servo motor, etc.), and the motor may increase the torque through a reducer to meet the driving requirements. Optionally, the first driving part also includes a transmission device, such as a gear, a belt, a chain, etc., for converting the rotational motion of the motor into a linear motion.

[0043] The first mounting portion is located on the upper part of the first driving portion, and the first mounting portion is used to fix the mounting frame 21. The mounting frame 21 and the first mounting portion can be connected to each other by plugging, threading or welding, so as to be firmly connected to the mounting frame 21.

[0044] When the motor is started, the rotational motion is converted into linear motion of the first mounting part through the transmission device. The first mounting part moves on the annular guide rail 1, thereby driving the mounting frame 21 and the guide member 2 connected thereto to move together. In addition, the first drive member 3 enables the guide device to be automatically or remotely controlled, and adjusts the position of the guide member 2 according to changes in the ambient wind speed and wind direction, thereby improving the cooling efficiency of the air-cooling tower 100. In the case of rapidly changing wind conditions, the first drive member 3 can respond quickly and adjust the state of the guide device to protect the air-cooling tower 100 from the influence of the wind. In other words, due to the reduction of human intervention, the automated drive device can reduce the risk of operational errors and improve the reliability of the system.

[0045] In some embodiments, the flow guide device for the outside of the air cooling tower of the embodiment of the present invention also includes a second driving member 4, the second driving member 4 includes a second mounting portion and a second driving portion, the second mounting portion is connected to the first mounting portion, the second driving portion is connected to the mounting frame 21, and the second driving portion is used to drive the mounting frame 21 to rotate around the first axial direction.

[0046] It is understandable that if Figure 1-Figure 4 As shown, the second mounting portion is a component for connecting the first mounting portion and the second driving portion to ensure a stable connection between the first mounting portion and the second driving portion, and allow the two to work together. The second driving portion is a power component for driving the mounting frame 21 to rotate around the first axial direction. The second driving portion includes one or more motors that can provide sufficient torque to achieve the rotation of the mounting frame 21. And the second driving portion also includes a reduction device to adapt to the required torque and speed requirements. Optionally, the second driving portion also includes a transmission mechanism (such as gears, belts, chains, etc.) that may be used to convert the rotational motion of the motor into the rotational motion of the mounting frame 21.

[0047] In some embodiments, the flow guide device for the outside of the air cooling tower according to the embodiment of the present invention further includes a damping member 5 , which is detachably connected to the first mounting portion, and at least a portion of the damping member 5 abuts against the mounting frame 21 .

[0048] It is understandable that the damping member 5 is connected to the first mounting portion by a detachable connection, for example, bolts, buckles, latches, etc. can be used between the bottom of the damping member 5 and the first mounting portion to facilitate installation and maintenance. At least a portion of the damping member 5 (i.e., the portion adjacent to the mounting frame 21) is against the mounting frame 21, and the portion can be a soft rubber or silicone pad, or a metal or plastic member with elasticity and damping properties.

[0049] That is, when the flow guide device is acted upon by external forces (such as wind), the damping member 5 absorbs energy through its elastic deformation, thereby reducing the impact force transmitted to the mounting frame 21 and the flow guide 2. The damping member 5 can also reduce the vibration generated by the flow guide device when it moves or rotates, thereby improving the dynamic stability of the system. The damping member 5 can be in the form of a block, a pad, a rod, or other shapes suitable for absorbing vibration and impact.

[0050] Preferably, there are multiple damping members 5, and the multiple damping members 5 are arranged in the thickness direction of the mounting frame 21 (eg Figure 3 In the front-to-back direction, the two sides of the mounting frame 21 are arranged relatively. It can be understood that Figure 3 and Figure 4 As shown, a plurality of damping members 5 are respectively arranged at the front and rear sides of the mounting frame 21 in the front-rear direction of the mounting frame 21 .

[0051] That is, the damping member 5 can significantly reduce vibration and noise caused by wind force, etc., and improve the operating environment of the air cooling tower 100. And by reducing the impact force, the damping member 5 helps to protect the structural parts of the guide device and prolong its service life. When the guide device moves or rotates, the damping member 5 can provide stable support and reduce potential damage caused by instability.

[0052] Preferably, the rolling shutter curtain 22 includes a plurality of shutter curtain pieces 221 , and in the height direction of the mounting frame 21 , the ratio of the distance between two adjacent shutter curtain pieces 221 to the width of one shutter curtain piece 221 is greater than or equal to 0.1 and less than or equal to 0.3.

[0053] It is understandable that if Figure 6 As shown, the distance between two adjacent shutter curtain pieces 221 is a, and the width of the shutter curtain piece 221 is b, then That is, the shape, size and arrangement of the shutter blades 221 need to take into account the principles of aerodynamics to ensure that air can pass through the guide device smoothly while reducing resistance and noise.

[0054] In addition, the shutter curtain piece 221 can be made of a lightweight material with good weather resistance, such as aluminum alloy, stainless steel or special plastic, so as to withstand the influence of wind and environmental conditions.

[0055] In some embodiments, the mounting frame 21 further includes a mounting groove 222, which is formed on the inner wall surface of the mounting frame 21, and a portion of the roller shutter curtain 22 is placed in the mounting groove 222. Figure 3-Figure 5 As shown, the shutter curtain 22 also includes a retractable assembly, which is used to collect and release multiple shutter curtain pieces 221. The retractable assembly is placed in the mounting groove 222 to prevent the retractable assembly from being damaged by external forces during use. In addition, both ends of the shutter curtain piece 221 are also placed in the mounting groove 222, so that the sealing performance between the shutter curtain 22 and the mounting frame 21 is better during use.

[0056] In other embodiments, the shutter curtain 22 includes a first curtain 223 and a second curtain 224, and the first curtain 223 and the second curtain 224 are arranged at intervals along the thickness direction of the mounting frame 21. It can be understood that, if Figure 5 As shown, the first curtain 223 and the second curtain 224 are arranged side by side in the front-to-back direction, and the two can serve as backup for each other, that is, when the first curtain 223 cannot work normally for some reason, the second curtain 224 can also provide certain protection. In addition, the design of the double-layer roller shutter curtain 22 provides more control options. The first curtain 223 and the second curtain 224 can be opened and closed independently or simultaneously to meet different air flow requirements.

[0057] That is to say, the two layers of curtains can provide better sealing effect, especially in the closed state, they can fit tightly to reduce air leakage, and by adjusting the interval and opening and closing state between the two layers of curtains, the air flow path can be optimized and the cooling efficiency of the air cooling tower 100 can be improved.

[0058] In some further embodiments, in the second state, the first curtain 223 is spaced apart from the upper end of the mounting frame 21 , and the second curtain 224 is spaced apart from the lower end of the mounting frame 21 .

[0059] It is understandable that if Figure 6 and Figure 7 As described above, the first curtain 223 is opened from bottom to top, while the second curtain 224 is opened from top to bottom. Thus, the first curtain 223 and the second curtain 224 can be opened at different positions to make the interval between the mounting frame 21 have different opening and closing degrees, thereby being suitable for different use environments.

[0060] Alternatively, if Figure 6 As shown, the shutter curtain piece 221 also has a plurality of vent holes 225, which penetrate the shutter curtain piece 221 along the thickness direction of the shutter curtain piece 221, and the plurality of vent holes 225 extend along the extension direction of the shutter curtain piece 221 (such as Figure 3 It is understood that the plurality of vent holes 225 are arranged on the shutter sheet 221, so that in a windy environment, a small amount of gas can be allowed to pass through while ensuring sealing, thereby reducing the pressure difference caused by gas accumulation and improving the sealing performance. In addition, the interval arrangement of the vent holes 225 can help prevent the shutter sheet 221 from being deformed due to force, that is, it can provide a certain degree of elasticity in different directions.
