[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Example 1:

[0029] A noise reduction device for a gas compressor includes a base 1 and an air compressor 3 mounted above the base 1. The base 1 is provided with a placement slot 101 corresponding to a soundproof cover 4. The bottom of the soundproof cover 4 is placed within the placement slot 101, providing a suitable storage location for the soundproof cover 4. An air inlet duct 301 and an air outlet duct 302 are located above the air compressor 3. Air is drawn in through the air inlet duct 301 and discharged through the air outlet duct 302. A connecting base 303 is fixedly connected to the bottom of the air compressor 3. A damping rod 304 is fixedly connected to the periphery of the lower surface of the connecting base 303. A spring 305 is connected to the outer side of the damping rod 304. The bottom of the damping rod 304 is connected to the upper surface of the base 1. The damping rod 304 and the spring 305 together form a shock absorption system that effectively absorbs vibrations generated by the air compressor 3 during operation, reducing noise and mechanical damage. A soundproof cover 4 is provided outside the air compressor 3, wrapping around the exterior of the air compressor 3 to provide sound insulation and noise reduction. The interior of the soundproof cover 4 is covered with a layer of glass wool sound-absorbing material, which can further absorb noise and improve the noise reduction effect. The outside of the soundproof cover 4 is provided with a lifting structure, and the front and rear sides of the soundproof cover 4 are provided with cooling mechanisms;

[0030] The cooling mechanism includes an air cooling unit;

[0031] The air cooling unit includes a heat dissipation fin 5, a connecting rod 601, a heat dissipation support frame 602, a groove 603, a second threaded rod 604, a second motor 605, a slider 606, a screw nut 607 and a heat dissipation fan 608. The heat dissipation fin 5 is fixedly connected to the back of the sound insulation cover 4, the connecting rod 601 is fixedly connected to the four sides of the heat dissipation support frame 602, and the other end of the connecting rod 601 is fixedly connected to the back of the sound insulation cover 4. The grooves 603 are respectively provided on the upper and lower surfaces of the heat dissipation support frame 602, the second threaded rod 604 is arranged in the lower groove 603, the output end of the second motor 605 is connected to the second threaded rod 604 through a coupling, the screw nut 607 is threadedly connected to the second threaded rod 604, the slider 606 is slidably connected to the upper groove 603, and the upper and lower surfaces of the heat dissipation fan 608 are fixedly connected between the screw nut 607 and the slider 606. The rotation of the heat dissipation fan 608 accelerates the air flow, takes away the heat inside the sound insulation cover 4, and achieves cooling. The adjustment mechanism composed of the second motor 605 and the second threaded rod 604 and other components can adjust the position of the cooling fan 608 to adapt to different cooling requirements.

[0032] Example 2: Based on Example 1, the cooling mechanism further includes a water cooling unit, comprising a heat sink 7, a support base 8, a chute 801, two electric push rods 802, and a first magnet 803. The back of the heat sink 7 is fixedly connected to the front of the soundproof enclosure 4, the support base 8 is fixedly connected to the bottom of the heat sink 7, the chute 801 is disposed within the support base 8, the electric push rod 802 is fixedly connected to one side of the chute 801, and the output end of the electric push rod 802 is connected to the first magnet 803. A second magnet 804 is disposed on the bottom of the heat sink 7. The sides of the first and second magnets 803 and 804 that are close to each other attract each other. Coolant is contained within the heat sink 7. The electric push rod 802 drives the first magnet 803 to move. Due to the attraction between the first and second magnets 803 and 804, the second magnet 804 follows the movement of the first magnet 803, thereby stirring the coolant and facilitating heat dissipation from the heat sink 7.

[0033] The lifting mechanism comprises a sliding seat 201, a fixed plate 202, a motor 203, and a threaded rod 204. The bottom of the sliding seat 201 is fixedly connected to the upper surface of the base 1, while the bottom surface of the fixed plate 202 is fixedly connected to the upper surface of the sliding seat 201. The motor 203 is threadedly connected to the front of the fixed plate 202 via bolts. The output end of the motor 203 is connected to the sliding seat 201 via a coupling. The threaded rod 204 is disposed within the sliding seat 201. A connecting block is threadedly connected to the threaded rod 204, which is fixedly connected to the soundproof enclosure 4. The lifting mechanism comprises two groups, one on each side of the soundproof enclosure 4. The rotation of the motor 203 drives the threaded rod 204, thereby driving the soundproof enclosure 4 up and down, facilitating maintenance and operation. The two groups of lifting mechanisms ensure stable raising and lowering of the soundproof enclosure 4, improving the safety and reliability of the device.

[0034] Working Principle: The air compressor 3 is connected to the damping rod 304 and spring 305 via the connector 303, forming a shock-absorbing system. When the air compressor 3 is operating, the vibrations generated are effectively absorbed by the damping rod 304 and spring 305, reducing noise and mechanical damage. The soundproof cover 4 wraps around the outside of the air compressor 3, providing sound insulation and noise reduction. The glass wool sound-absorbing material covering the interior of the soundproof cover 4 further absorbs noise, enhancing the noise reduction effect. When the air compressor 3 is operating, heat is generated in the cavity within the soundproof cover 4. The cooling mechanism is installed on the outside of the soundproof cover 4. The air-cooling unit accelerates air flow through the rotation of the cooling fan 608, removing heat from the interior of the soundproof cover 4. The water-cooling unit stirs the coolant in the heat dissipation tank 7 to dissipate heat more quickly. The electric push rod 802 drives the magnetic block 1 803 to move. Due to the attraction between the magnetic block 1 803 and the magnetic block 2 804, the magnetic block 2 804 moves with it, stirring the coolant and improving heat dissipation efficiency.

[0035] When the air compressor 3 needs to be repaired, the motor 1 203 is started, and the rotation of the motor 1 203 drives the threaded rod 1 204 to rotate, thereby driving the sound insulation cover 4 to rise and fall, which is convenient for maintenance and operation.
