The left side of the rotating rod 42 penetrates through the left side of the connection box 41 and is fixedly connected to the turntable 43. The surface of the rotating rod 42 and inside the connection box 41 is fixedly sleeved with the threaded cylinder 44. The bottom of the right inner wall of the connection box 41 is movably connected to the transmission rod 45 through a bearing seat.

[0023] As a technical optimization solution of the present invention, through the setting of the limiting mechanism 6, the moving plate 48 can drive the sliding plate 64 to move accordingly, and the sliding plate 64 moves stably inside the rectangular plate 61, so that the moving direction of the moving plate 48 is stable.

[0024] Reference Figure 5 , a slide rail 7 is provided at the back end of the rectangular plate 61 corresponding to the position of the sliding plate 64, and the slide rail 7 is used in cooperation with the sliding plate 64.

[0025] As a technical optimization solution of the present invention, through the setting of the slide rail 7, the sliding plate 64 can move left and right inside the slide rail 7, and at the same time play a role in limiting, avoiding the phenomenon that the sliding plate 64 breaks away during the movement.

[0026] Reference Figure 4 , a reinforcing block 8 is fixedly connected to the left side of the moving plate 48 corresponding to the position of the sliding plate 64, and the reinforcing block 8 is used in cooperation with the sliding plate 64.

[0027] As a technical optimization solution of the present invention, through the setting of the reinforcing block 8, it can assist the sliding plate 64 to work and at the same time play a role in strengthening, avoiding the phenomenon that the sliding plate 64 is deformed and broken due to excessive load during the movement.

[0028] Reference Figure 3 , mounting blocks 9 are fixedly connected to the front end and the back end of the top of the U-shaped plate 35 corresponding to the position of the connection box 41, and the mounting blocks 9 are used in cooperation with the connection box 41.

[0029] As a technical optimization solution of the present invention, through the setting of the mounting block 9, it can assist the connection box 41 to be fixedly installed, avoiding the phenomenon that the connection box 41 becomes loose on the surface of the U-shaped plate 35.

[0030] Reference Figure 4 , anti-slip grooves are provided at the front end and the back end of the surface of the turntable 43, and the turntable 43 is used in cooperation with the anti-slip grooves.

[0031] As a technical optimization solution of the present invention, through the setting of the turntable 43, the frictional resistance can be increased, avoiding the phenomenon of slipping and loosening during the process of the user's hand-held operation.

[0032] Reference Figure 2 , clamping grooves are provided at the left end and the right end of the inner side of the U-shaped plate 35 corresponding to the position of the perforated plate 51, and the U-shaped plate 35 is used in cooperation with the perforated plate 51.

[0033] As a technical optimization solution of the present invention, through the setting of the U-shaped plate 35, it can assist the perforated plate 51 to work and at the same time play a role in positioning, avoiding the situation that the U-shaped plates 35 are installed too close to each other and cannot achieve the effect.

[0034] Working principle and usage process of the present invention: When in use, start the operation of the electric telescopic rod 32. The operation of the electric telescopic rod 32 adjusts the up-and-down movement of the connecting plate 33. The up-and-down movement of the connecting plate 33 drives the overall up-and-down adjustment of the V-shaped plate 34 and the U-shaped plate 35 to be at the height position of the cooling tower body 1. Then, the perforated plate 51, the low-density sound-absorbing material 52, and the high-density sound-absorbing material 53 are integrally inserted into the card slot of the U-shaped plate 35. Then, manually rotate the turntable 43. The clockwise rotation of the turntable 43 drives the rotation of the rotating rod 42 and the threaded barrel 44. The rotation of the threaded barrel 44 drives the rotation of the toothed ring 47. The rotation of the toothed ring 47 drives the double-toothed disk 46 and the transmission rod 45 to rotate accordingly. When the double-toothed disk 46 rotates, it drives the toothed plate 49 to move to the right. The movement of the toothed plate 49 to the right drives the moving plate 48 to move accordingly. When the moving plate 48 moves, it drives the sliding plate 64 to stably move along the slide rail 7 inside the rectangular plate 61. Then, the moving plate 48 moves out of the outside of the connection box 41 and is on both sides of the U-shaped plate 35 to clamp and position the perforated plate 51, preventing the perforated plate 51 from detaching from the inside of the U-shaped plate 35. When the noise of the cooling tower body 1 passes through the perforated plate 51, it is transmitted from the low-density sound-absorbing material 52 to the high-density sound-absorbing material 53, and the sound-absorbing effect is better. Coupled with the arc-shaped setting of the perforated plate 51, a higher noise reduction amount can be achieved. In addition, the arc-shaped arrangement of the perforated plate 51 can prevent high-frequency noise from directly passing through, avoiding high-frequency failure. Moreover, the arc-shaped outer shape of the perforated plate 51 can force the incoming air flow to be converted from the horizontal direction to the vertical direction, making the air flow uniformity of the packing layer of the cooling tower body 1 better and more conducive to the normal operation of the cooling tower body 1. Similarly, the turntable 43 can be rotated in the reverse direction to control the moving plate 48 to retract into the inside of the connection box 41 and separately take out the perforated plate 51 for maintenance. It is also possible to control the number of perforated plates 51 on the U-shaped plate 35 to cope with noise adjustments of different degrees.

[0035] In summary: The silencer for the air inlet of the high-position cooling tower with a diversion function, through the cooperation of the cooling tower body 1, the connecting seat 2, the lifting mechanism 3, the seat body 31, the electric telescopic rod 32, the connecting plate 33, the V-shaped plate 34, the U-shaped plate 35, the positioning mechanism 4, the connection box 41, the rotating rod 42, the turntable 43, the threaded barrel 44, the transmission rod 45, the double-toothed disk 46, the toothed ring 47, the moving plate 48, the toothed plate 49, the sound-absorbing mechanism 5, and the limiting mechanism 6, solves the problems that the length of the existing sheet-type silencer is limited, and due to the arrangement of the sheet-type silencer, it is difficult for the air flow to pass through directly above the sheet-type silencer, which has an adverse effect on the normal use of the high-position cooling tower.
