[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a noise reduction structure for an air compressor, comprising a support plate 1, two bottom shock absorbing devices 7 are installed above the support plate 1, a shock absorbing plate 6 is arranged above the two bottom shock absorbing devices 7, an air compressor assembly 5 is installed above the shock absorbing plate 6, side shock absorbing devices 2 are installed on both sides of the air compressor assembly 5, a temperature sensor 4 is installed above the air compressor assembly 5, the two bottom shock absorbing devices 7 are connected to the shock absorbing plate 6 through a noise reduction and moisture-proof device 3, and a mobile support device 8 is installed below the support plate 1.

[0023] Specifically, the noise reduction and moisture-proof device 3 includes a fixed frame 31, a first sound-absorbing cotton 32, a second sound-absorbing cotton 33, a movable frame 34, a moisture-proof component 35, a screw 36, a movable plate 37 and a motor 38. The fixed frame 31 is installed between the two bottom shock-absorbing devices 7, the shock-absorbing plate 6 and the two side shock-absorbing devices 2 and located outside the shock-absorbing plate 6 and the two side shock-absorbing devices 2. The first sound-absorbing cotton 32 is installed at the bottom of the fixed frame 31, and two motors 38 are installed above the fixed frame 31. Screws 36 are installed on both sides of the two motors 38 away from each other, and a movable plate 37 is installed on the outside of the screw 36 through threads. The movable frame 34 is installed on the movable plate 37 and located outside the fixed frame 31. The second sound-absorbing cotton 33 is installed in the side wall of the movable frame 34, and moisture-proof components 35 are installed on both sides of the fixed frame 31 near the edge.

[0024] By adopting the above technical solution, the staff can choose whether to perform noise reduction work when necessary through the cooperation of structures such as the screw rod 36 and the movable plate 37, so as to better meet the work needs in different situations.

[0025] Specifically, the height of the outer bottom surface of the movable plate 37 is equal to the height of the outer top surface of the fixing frame 31 .

[0026] By adopting the above technical solution, the structure can ensure that the outer bottom surface of the movable plate 37 and the outer top surface of the fixed frame 31 can be closely attached to each other, thereby preventing the movable plate 37 from rotating and deviating during the movement process.

[0027] Specifically, the moisture-proof component 35 includes a mesh tube 351 and a silica gel desiccant 352 . The mesh tubes 351 are installed at the edge positions of both sides of the fixing frame 31 , and the silica gel desiccant 352 is arranged inside the mesh tube 351 .

[0029] When this embodiment is used, when the air compressor needs to use the structure for noise reduction, the two motors 38 in the noise reduction and moisture-proof device 3 are started, thereby driving the two screw rods 36 to rotate. The screw rods 36 are threadedly connected to the movable plate 37, and the movable plate 37 and the fixed frame 31 are tightly attached to each other, so the two screw rods 36 drive the two movable frames 34 to move until the two movable frames 34 and the fixed frame 31 are tightly attached to each other, and then the noise generated by the air compressor assembly 5 is silenced and reduced by the cooperation of the first silencer cotton 32 and the second silencer cotton 33.

The lifting frame 81 is installed below the support plate 1, and the base plate 83 is arranged on the inner side of the lifting frame 81. The electric lifting column 82 is installed between the outer top surface of the base plate 83 and the inner top surface of the lifting frame 81, and a plurality of brake wheels 84 are installed below the base plate 83.

[0032] By adopting the above technical solution, the staff can move the position of the structure to a certain extent through the brake wheel 84 when necessary, thereby reducing the difficulty of moving the structure and alleviating the labor burden of the staff.

[0033] Specifically, the movable support device 8 further includes a friction rubber ring 85 , and the friction rubber ring 85 is installed below the lifting frame 81 .

[0034] By adopting the above technical solution, the structure can enhance the friction between the lifting frame 81 and the ground through the friction rubber ring 85, thereby reducing the possibility of accidental movement of the structure when it is not needed.

[0035] When the present embodiment is used, when the position of the structure needs to be moved, the electric lifting column 82 in the mobile support device 8 is started, thereby driving the lifting frame 81 to move until the friction rubber ring 85 is separated from the ground, and then the structure is pushed, and the structure is moved to a specified position through the brake wheels 84 under the bottom plate 83, and then the electric lifting column 82 is started, so that the friction rubber ring 85 contacts the ground again, and the movement is completed.

The sound-absorbing layer adopts glass wool to improve the sound insulation and noise reduction effect. A side shock-absorbing device is provided between the air compressor and the soundproof cabin to further buffer the vibration generated by the air compressor. A temperature sensor is provided on the top of the inner cavity of the soundproof cabin. The temperature sensor is connected to the control system of the oxygen generator. A semiconductor refrigeration plate is provided on the outer wall of the air compressor. The temperature sensor monitors the internal temperature of the soundproof cabin in real time. When the internal temperature of the soundproof cabin is too high, the temperature sensor feeds back the information to the control system of the oxygen generator. The control system of the oxygen generator controls the operation of the semiconductor refrigeration plate to cool down the inside of the soundproof cabin to ensure the normal operation of the air compressor.

[0037] The working principle and use process of the utility model are as follows: when the air compressor needs to use the structure for noise reduction, the two motors 38 in the noise reduction and moisture-proof device 3 are started, thereby driving the two screw rods 36 to rotate, the screw rods 36 are threadedly connected to the movable plate 37, and the movable plate 37 and the fixed frame 31 are tightly attached to each other, so the two screw rods 36 drive the two movable frames 34 to move until the two movable frames 34 and the fixed frame 31 are tightly attached to each other, and then the noise generated by the air compressor component 5 is silenced and reduced by the cooperation of the first silencer cotton 32 and the second silencer cotton 33, and the side shock absorbing device 2, the shock absorbing plate 6 and the bottom shock absorbing device 3 are used to reduce the noise. The vibration device 7 can buffer the vibration caused by the air compressor assembly 5, the temperature sensor 4 plays a role in measuring temperature, the silica gel desiccant 352 in the mesh tube 351 in the moisture-proof assembly 35 can play a role in moisture-proof and drying, and the support plate 1 plays a supporting role; when the position of the structure needs to be moved, the electric lifting column 82 in the mobile support device 8 is started, thereby driving the lifting frame 81 to move until the friction rubber ring 85 is separated from the ground, and then the structure is pushed, and the structure is moved to the specified position through the various brake wheels 84 under the bottom plate 83, and then the electric lifting column 82 is started, so that the friction rubber ring 85 is re-contacted with the ground, and the movement is completed.
