[0002] A cooling tower is an industrial equipment that dissipates heat into the atmosphere through the circulation of water to lower the temperature of the water and achieve the purpose of cooling. A cooling tower is usually composed of a cooler, a water pump, a water tank, a radiator and a fan. Its working principle is to spray hot water into the cooling tower through a spray device, and heat is exchanged with the air through a heat exchanger in the cooler to lower the temperature of the water.
[0003] Since the cooling tower itself is a large equipment, its operation will generate strong vibrations, resulting in loud noise. In real life, most people only install sound-absorbing cotton on the outside of the cooling tower to reduce noise. The vibration generated by the operation of the cooling tower is not dealt with, so the actual noise reduction effect is not ideal, which will affect the living environment of surrounding residents. Utility Model Content

[0006] As a further improvement of the present technical solution, the fixing assembly includes a sliding column fixedly connected to the bottom end of the upper fixing plate, a storage column is slidably connected to the outer side of the sliding column, the bottom end of the storage column is fixedly connected to the lower fixing plate, and multiple groups of sliding columns and storage columns are fixedly connected between the upper fixing plate and the lower fixing plate and are evenly distributed in a circular manner.
[0007] As a further improvement of the present technical solution, the auxiliary shock absorbing mechanism includes a fixed cylinder fixedly connected at the four corners of the top end of the base plate, a movable cylinder is slidably connected inside the fixed cylinder, the top end of the movable cylinder is fixedly connected to the workbench, fixed plates are fixedly connected to the outer sides of the movable cylinder and the fixed cylinder, and a second buffer spring for assisting shock absorption of the cooling box is fixedly connected between a pair of fixed plates.
[0008] As a further improvement of the technical solution, grooves are provided in the inner walls around the shell and extend to the top, and a sound insulation board is slidably connected to the inside of the groove.
[0009] As a further improvement of the technical solution, handles for replacing the sound insulation boards are fixedly connected to the top ends of the four sound insulation boards.
[0010] As a further improvement of the technical solution, an arc-shaped sound-absorbing panel is fixedly connected between every two adjacent sound insulation panels.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. When the closed cooling tower noise reduction device is running, the internal parts will generate strong vibrations, which makes the noise louder. Therefore, by setting the first buffer spring and the second buffer spring, the sliding connection between the sliding column and the storage column, the fixed cylinder and the movable cylinder cooperates with the buffer spring to reduce the vibration amplitude and correspondingly reduce the noise decibel of the device.

At the same time, the moving cylinder 11 slides inside the fixed cylinder 10, and the sliding column 8 slides inside the storage column 9, so that the workbench 4 is Always keep it in a horizontal state to prevent the cooling box 2 from moving due to vibration when the equipment is running. By opening a groove in the inner wall around the shell 1 and installing a sound insulation board 14 inside the groove, the noise is absorbed and the noise decibel is further reduced. The setting of the arc sound-absorbing board 16 avoids the noise passing through the gap between the sound insulation boards 14 without being processed. At the same time, the four sound insulation boards 14 are connected as a whole by the arc sound-absorbing board 16.
