An exhaust duct 3 is fixedly connected to the top surface of the cooling tower body 1, and the number of exhaust ducts 3 is two, and the two exhaust ducts 3 are arranged in parallel, and exhaust fans 4 are fixedly installed in the two exhaust ducts 3. A fixed frame 5 is fixedly installed in each air inlet 2, and a main guide vane 6 and a secondary guide vane 7 are installed in the fixed frame 5, wherein the number of the secondary guide vanes 7 is multiple, and the multiple secondary guide vanes 7 are symmetrically arranged with the main guide vane 6 as the center. The two ends of the main guide vane 6 and the multiple secondary guide vanes 7 are respectively fixedly connected with a transmission shaft 8, and the main guide vane 6 and the multiple secondary guide vanes 7 are respectively rotatably installed in the fixed frame 5 through the transmission shaft 8. The fixed frame 5 is also equipped with a transmission mechanism, and the transmission mechanism is used to drive the main guide vane 6 and the multiple secondary guide vanes 7 to swing at the same time.

[0028] The main function of the cooling tower body 1 is to reduce the water temperature through heat exchange between water and air, thereby ensuring the normal operation of the system. When the exhaust fan 4 in the exhaust duct 3 is started, dry air from the outside is sucked into the cooling tower body 1 from the air inlet 2. When the dry air flows through the air inlet 2, the main guide vane 6 and multiple auxiliary guide vanes 7 guide the dry air so that the dry air flows evenly into the cooling tower body 1 and performs heat exchange on the inclined tubes in the cooling tower body 1. When it is necessary to adjust the guide angles of the main guide vane 6 and the auxiliary guide vane 7, the main guide vane 6 and the auxiliary guide vane 7 are driven to swing at the same time through the transmission mechanism, thereby improving the cooling effect of the inclined tubes in the cooling tower body 1 according to the actual required air inlet direction.

[0029] For details, see Figure 2-Figure 4 The transmission mechanism includes a rack 9, one end of a transmission shaft 8 extends into the frame cavity of the fixed frame 5, and a gear 10 is fixedly sleeved on one end of the transmission shaft 8. The rack 9 is vertically arranged, and the rack 9 is slidably installed in the frame cavity of the fixed frame 5, and the rack 9 is meshed with multiple gears 10 at the same time.

[0030] In addition, in order to facilitate the swinging of the main flow blade 6, the fixed frame 5 is also equipped with a swing assembly, which includes a swing pair 11 and a swing rod 12. The side wall of the main flow blade 6 is provided with a swing groove 13, and the swing rod 12 is installed in the fixed frame 5, one end of the swing rod 12 extends into the swing groove 13, and one end of the swing rod 12 is hinged to the groove wall of the swing groove 13.

The swing pair 11 is set at an obtuse angle, and one end of the swing pair 11 is fixedly connected to the connecting shaft 15, and the other end of the swing pair 11 is rotatably connected to the swing rod 12.

[0031] When the connecting shaft 15 is driven to rotate, the connecting shaft 15 drives the swinging pair 11 set at an obtuse angle to swing. Under the continuous rotation of the connecting shaft 15, the swinging pair 11 drives the swinging rod 12 to swing, and the swinging rod 12 drives the main guide vane 6 to swing back and forth. The main guide vane 6 drives the gear 10 to rotate back and forth through the transmission shaft 8, and the gear 10 drives the rack 9 to move up and down, and the rack 9 then drives the auxiliary guide vane 7 to swing back and forth through the corresponding gear 10. By swinging and guiding the main guide vane 6 and the auxiliary guide vane 7 at the same time, the dry air flowing through the air inlet 2 is evenly blown to the inclined tube in the cooling tower body 1, thereby improving the cooling effect of the inclined tube.

[0032] See also Figure 3 and Figure 4In order to facilitate the continuous rotation of the connecting shaft 15, a driving member is installed on the fixed frame 5, and the driving member is a fan body 16. The fan body 16 is rotatably and movably installed in the fixed frame 5. A cross bar 17 is coaxially fixedly connected to the inner side of the fan body 16. A block 18 is fixedly connected to one end of the cross bar 17 facing the main flow blade 6. A square groove 19 is opened at the end of the connecting shaft 15 away from the main flow blade 6, and the block 18 is plugged into the square groove 19.

[0033] When dry air flows through the air inlet 2, the dry air drives the fan body 16 to rotate, the fan body 16 drives the cross bar 17 to rotate, the cross bar 17 drives the connecting shaft 15 to rotate continuously through the block 18, the connecting shaft 15 drives the swing pair 11 to rotate, the swing pair 11 drives the swing rod 12 to swing, the swing rod 12 then drives the main guide vane 6 to swing back and forth, and the main guide vane 6 finally drives the auxiliary guide vane 7 to swing synchronously.

[0034] It is worth noting that see Figure 2 , Figure 3 and Figure 5 In order to make the main guide vane 6 and the auxiliary guide vane 7 stationary at a certain swing angle, a moving rod 20 is rotatably sleeved on the side wall of the crossbar 17. The two ends of the moving rod 20 are L-shaped, and the two ends of the moving rod 20 extend into the frame cavity of the fixed frame 5. The inner wall of the fixed frame 5 is symmetrically provided with moving grooves 21, and the two ends of the moving rod 20 are slidably connected to the moving grooves 21.

[0035] In addition, in order to facilitate the fixing of the moving rod 20, the cooling tower body 1 is also equipped with a locking assembly, which includes a lock seat 22, which is fixedly connected to the outer wall of the fixed frame 5, and a lock rod 23 is slidably penetrated in the lock seat 22. The side wall of the moving rod 20 is provided with a lock hole 24, and the number of the lock holes 24 is set to two, and the two lock holes 24 are arranged in parallel, and the lock rod 23 is respectively plugged into the two lock holes 24. The side wall of the lock rod 23 is sleeved with a spring 25, one end of the spring 25 is fixedly connected to the side wall of the lock rod 23, and the other end of the spring 25 is fixedly connected to the inner wall of the lock seat 22.

[0036] When the continuous rotation of the connecting shaft 15 needs to be stopped, the locking rod 23 is driven to move away from the moving rod 20, the locking rod 23 squeezes the spring 25, and the locking rod 23 is separated from the locking hole 24. At this time, the moving rod 20 is released from the restriction, and the main deflector drives the cross bar 17 to move away from the main deflector by driving the moving rod 20 to move away from the main deflector, so that the cross bar 17 and the connecting shaft 15 are separated from each other. When the fan body 16 continues to rotate, the fan body 16 no longer drives the connecting shaft 15 to rotate.

[0037] See also Figure 6 and Figure 7In order to facilitate the adjustment of the guiding angles of the main guide vane 6 and the auxiliary guide vane 7, the end of the transmission shaft 8 corresponding to the main guide vane 6 away from the gear 10 also extends into the frame cavity of the fixed frame 5, and the end of the transmission shaft 8 away from the gear 10 is fixedly sleeved with a first bevel gear 26.

[0038] In addition, the fixed frame 5 is also equipped with a rotating member, which is used to drive the first bevel gear 26 to rotate. The rotating member is a knob 27, which is rotatably mounted on the surface of the fixed frame 5. One end of the knob 27 is coaxially fixedly connected to a rotating rod 28, and one end of the rotating rod 28 penetrates and extends into the frame cavity of the fixed frame 5. One end of the rotating rod 28 is fixedly sleeved with a second bevel gear 29, and the second bevel gear 29 is meshed with the first bevel gear 26.

[0039] When the knob 27 is turned, the knob 27 drives the second bevel gear 29 to rotate through the rotating rod 28, the second bevel gear 29 drives the first bevel gear 26 to rotate, the first bevel gear 26 drives the main guide vane 6 to swing through the transmission shaft 8, and the main guide vane 6 finally drives the auxiliary guide vane 7 to swing through the gear 10 and the rack 9, thereby realizing manual change of the guide angles of the main guide vane 6 and the auxiliary guide vane 7.

[0040] It should be noted that, in order to improve safety performance, when using the cooling tower body 1, a ventilation shield is provided on the outside of the fixing frame 5 to prevent injuries caused by accidentally touching the fan body 16.

[0041] The working principle of a cooling tower with a circulating water cooling wind guide device: The main function of the cooling tower body 1 is to reduce the water temperature through heat exchange between water and air, thereby ensuring the normal operation of the system. When the exhaust fan 4 in the exhaust duct 3 is started, dry air from the outside is sucked into the cooling tower body 1 from the air inlet 2. When the dry air flows through the air inlet 2, the main guide vane 6 and the plurality of auxiliary guide vanes 7 guide the dry air so that the dry air flows evenly into the cooling tower body 1 and performs heat exchange on the inclined tubes in the cooling tower body 1.

[0042] When the main guide vane 6 and the plurality of auxiliary guide vanes 7 need to be swung back and forth to adjust, the locking rod 23 is driven to move in a direction away from the moving rod 20, the locking rod 23 squeezes the spring 25, and the locking rod 23 is separated from the locking hole 24, and the moving rod 20 is now freed from restriction. After the moving rod 20 is freed from restriction, the moving rod 20 is driven to move in a direction close to the main guide vane 6, and the moving rod 20 drives the cross bar 17 to move in a direction close to the main guide vane 6, and at this time the cross bar 17 is inserted into the square groove 19 through the square block 18. Then the locking rod 23 is released, the spring 25 releases its elastic force, and drives the locking rod 23 to be inserted into the locking hole 24, and the moving rod 20 is fixed at the current position.

[0043] When dry air is sucked and flows through the air inlet 2, the dry air drives the fan body 16 to rotate, the fan body 16 drives the cross bar 17 to rotate, the cross bar 17 drives the connecting shaft 15 to rotate continuously through the block 18, the connecting shaft 15 drives the swing pair 11 to rotate, the swing pair 11 drives the swing rod 12 to swing, and the swing rod 12 then drives the main guide vane 6 to swing back and forth, the main guide vane 6 finally drives multiple auxiliary guide vanes 7 to swing back and forth synchronously, at this time, the dry air is evenly blown to the inclined tube in the cooling tower body 1, and the dry air is finally discharged from the exhaust duct 3 after heat exchange with the inclined tube.

[0044] When the main guide vane 6 and the auxiliary guide vane 7 need to be stationary at a certain swing angle, the lock rod 23 is repeatedly driven to move in the direction away from the moving rod 20 to release the restriction of the moving rod 20, and then the main guide plate drives the cross bar 17 to move in the direction away from the main guide plate by driving the moving rod 20, so that the cross bar 17 and the connecting shaft 15 are separated from each other. When the fan body 16 continues to rotate, the fan body 16 no longer drives the connecting shaft 15 to rotate. Then, the knob 27 is turned, and the knob 27 drives the second bevel gear 29 to rotate through the rotating rod 28, and the second bevel gear 29 drives the first bevel gear 26 to rotate. The first bevel gear 26 drives the main guide vane 6 to swing through the transmission shaft 8. The main guide vane 6 finally drives the auxiliary guide vane 7 to swing through the gear 10 and the rack 9, thereby realizing the manual change of the guide angle of the main guide vane 6 and the auxiliary guide vane 7.

[0045] Embodiment 2: The difference from Embodiment 1 is that the structure of the transmission mechanism is different.

[0046] For details, see Figure 8 and Fig. 9 The transmission mechanism includes a motor 30, one end of the transmission shaft 8 extends into the frame cavity of the fixed frame 5, the motor 30 is fixedly installed in the frame cavity of the fixed frame 5, the output shaft of the motor 30 is fixedly connected to the transmission shaft 8 corresponding to the main flow blade 6, and the motor 30 is electrically connected to the power supply. Adjacent transmission shafts 8 are respectively connected to synchronous pulleys 31.

[0047] When it is necessary to adjust the flow direction of the dry air, the motor 30 is started, and the output shaft of the motor 30 drives the transmission shaft 8 to rotate, and the transmission shaft 8 drives the main guide vane 6 to swing. The main guide vane 6 drives the adjacent transmission shaft 8 to rotate synchronously through the synchronous pulley 31, and the adjacent transmission shaft 8 then drives the corresponding auxiliary guide vane 7 to swing. At this time, the main guide vane 6 and multiple auxiliary guide vanes 7 swing synchronously and guide the dry air flowing through the air inlet 2, which is beneficial to improve the stability of the dry air flowing evenly to the inclined tube in the cooling tower.

[0048] In summary, under the joint guiding action of the main guide vane 6 and the plurality of auxiliary guide vanes 7, the flow direction of the dry air flowing through the air inlet 2 is changed so that the dry air is blown evenly toward the inclined tubes, thereby improving the cooling effect of the inclined tubes in the cooling tower.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
