[0034] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0036] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of the present invention, a twin-screw gas compressor includes: a mounting base 1; a compressor body 4, fixedly disposed on the outside of the mounting base 1; a noise-reducing shield 2, symmetrically disposed on the outside of the compressor body 4, with rotating shafts fixedly disposed on both outer walls of the shield and rotatably connected to the mounting base 1, and sound-absorbing cotton 3 disposed on the inner side of the shell wall of the noise-reducing shield 2; a control box 5, disposed on the outside of the compressor body 4 and fixedly connected to the mounting base 1; and a flip-opening / closing unit 6, connected to the mounting base 1 and symmetrically disposed, connected to the rotating shafts on both sides of the noise-reducing shield 2, for cooperating with the rotating shafts to realize the synchronous flip-opening and closing of the noise-reducing shield 2 on both sides; wherein, the flip-opening / closing unit 6 includes The system includes a flip control component 8 and an automatic locking component 9. The flip control component 8 is located between the control box 5 and the two noise reduction covers 2 on both sides, connected to the control box 5, and connected to a rotating shaft located on the outside of the noise reduction covers 2. It is used to cooperate with the control box 5 to realize the synchronous flipping of the two noise reduction covers 2 on both sides. The automatic locking component 9 is connected to the control box 5 and is arranged opposite to the flip control component 8. It is used to cooperate with the flip control component 8 to lock the two noise reduction covers 2 on both sides after they are closed. The system also includes a dust removal and air supply unit 7, which is connected to the control box 5 and connected to the two noise reduction covers 2 on both sides after they are closed. It is used to cooperate with the noise reduction covers 2 after they are closed to supply air to the compressor body 4.

[0037] In this embodiment, when the device is running and the compressor body 4 is ready to run, the flip control component 8 drives the noise reduction covers 2 on both sides to rotate around the connection with the mounting base 1. As the noise reduction covers 2 on both sides close, the flip control component 8 can drive the automatic locking component 9 to further lock the closed noise reduction covers 2, ensuring the stability and reliability of the noise reduction covers 2 during use. The sound-absorbing cotton 3 set inside the noise reduction covers 2 can effectively absorb the noise generated by the compressor body 4 during operation, making it difficult for the noise generated by the compressor body 4 to be transmitted to the ears of nearby personnel, thereby reducing the impact of noise on personnel and making it easier for personnel to operate near the compressor body 4 for a long time. In addition, the dust removal and air supply unit 7 will supply air to the operating space of the compressor body 4 after the noise reduction cover 2 is closed, and perform dust removal operation on the supplied air, so that the compressor body 4 can still operate stably after noise reduction, greatly improving work efficiency. This application sets up a flip opening and closing unit 6, which, together with the noise reduction cover 2, can automatically achieve the effect of sound insulation and noise reduction after the compressor body 4 is running, so that the noise generated by the compressor body 4 during operation is not easily transmitted to the ears of nearby personnel, thereby reducing the impact of noise on personnel, which is beneficial for personnel to operate near the compressor body 4 for a long time, and can stably supply air to the compressor body 4 after shielding and noise reduction, ensuring the stability and reliability of the compressor body 4 during operation.

[0038] In one embodiment of the present invention, please refer to Figure 4 , Figure 5 and Figure 7 The flipping control assembly 8 includes: an electric push rod 12, a control frame 13, a fixed rod 14, a control component 15, a guide tube 16, a flipping rack 20, a flipping gear 21, and a control piston 25.

The first push rod is slidably connected to the fixed rod 14, and a spring is fixedly disposed between the first push rod and the fixed rod 14. As the control component 15 moves inside the guide tube 16, the air inside the guide tube 16 enters the control slot, which, together with the control piston 25, drives the rotating rack 20 to move along the T-shaped guide. The rotating rack 20, together with the rotating gear 21 and the rotating shaft, realizes the rotation of the noise reduction cover 2, thereby realizing the opening and closing of the noise reduction cover 2. Through the openable and closable noise reduction cover 2, the operating compressor body 4 can be protected against noise reduction, and it is also convenient for people to maintain the compressor body 4, which enhances the convenience and safety of the equipment during use.

A spring is fixedly disposed between the adjustment frame 22 and the connecting block 23. A positioning rod 24 is fixedly disposed on the side wall of the adjustment frame 22 near the flipping rack 20. The shell wall of the flipping rack 20 is provided with a corresponding insertion hole for the positioning rod 24, which is used to lock the flipping rack 20 in conjunction with the positioning rod 24.

[0041] In this embodiment, as the rotating rack 20 cooperates with the rotating gear 21 to achieve the rotation and closure of the noise reduction shields 2 on both sides, after the noise reduction shields 2 on both sides are closed, the spring set between the connecting block 23 and the control frame 22 can push the control frame 22 to move. The positioning rod 24 on the control frame 22 will be inserted into the insertion hole on the rotating rack 20 to complete the locking of the rotating rack 20, thereby completing the auxiliary locking of the closed noise reduction shield 2, which helps to improve the stability of the equipment during operation.

[0042] In one embodiment of the present invention, please refer to Figure 3 and Figure 4The automatic locking component 9 includes a trapezoidal pressure block 17, a locking block 18, and a connecting plate 19. The trapezoidal pressure block 17 is symmetrically arranged on both sides of the control frame 13 and is fixedly connected to the control frame 13. A locking block 18 is provided below the inclined end of the trapezoidal pressure block 17. The locking block 18 is slidably connected to the connecting plate 19 fixedly arranged inside the control box 5. A spring is fixedly arranged between the connecting plate 19 and the locking block 18. A locking rod is fixedly arranged on the outer side of the locking block 18 away from the connecting plate 19. A locking groove adapted to the locking rod is provided on the inner wall of the noise reduction cover 2, which is used to cooperate with the locking rod to lock the noise reduction cover 2 after it is flipped and closed.

[0043] In this embodiment, as the control frame 13 moves downward, the noise reduction shields 2 on both sides flip and close. The control frame 13 continues to move downward, and the trapezoidal pressure blocks 17 on both sides of the control frame 13 drive the locking blocks 18 to move closer to the noise reduction shields 2 through the inclined side.

A collaborative cleaning component 11 connected to the drive rod 43 is provided on the outer side of the filter frame 33.

[0045] In this embodiment, as the noise reduction shield 2 closes, the motor 27 drives the drive rod 43 to rotate, which in turn drives the fan 29 to rotate. Outside air enters the air guide box 28 along the air inlet pipe 26 and then enters the dust collector 31 along the air delivery pipe 30. The filter frame 33 removes dust from the air, and the dust-removed air enters the working space along the air delivery pipe 32. The collaborative cleaning component 11, in conjunction with the rotation of the drive rod 43, sweeps the impurities attached to the filter frame 33 into the dust collection box 34. During cleaning, the collaborative cleaning component 11 first... The partition 35 is opened, and impurities are then swept into the inside of the sludge collection box 34. In addition, the elastic support 36 includes a support rod rotatably disposed inside the sludge collection box 34 and a connecting rod slidably connected to the support rod. A spring is fixedly disposed between the connecting rod and the support rod. The other end of the connecting rod is rotatably connected to the partition 35. By setting the dust removal and air supply unit 7, stable air supply can be provided to the compressor body 4 after shielding and noise reduction, and dust removal can be completed in the air supply process, effectively ensuring the stability and reliability of the compressor body 4 during operation.

[0046] In one embodiment of the present invention, please refer to Figure 8 and Figure 9 The collaborative cleaning component 11 includes: a moving guide block 37, a lifting plate 38, a cleaning brush 39, a sliding rod 40, a take-up and release plate 41, a lifting component 42, and a transmission and control component.

[0047] In this embodiment, the lifting component 42 includes a first push rod fixedly disposed on the outer side of the top of the lifting plate 38 and a first piston fixedly connected to the other end of the first push rod. The first piston is connected to the transmission and control component. The moving guide block 37 is parallelogram-shaped. During the rotation of the drive rod 43, the lifting plate 38 can be raised and lowered through the transmission and control component in conjunction with the lifting component 42. The lifting plate 38 drives the cleaning brush 39 to move up and down synchronously through the retracting plate 41. When the cleaning brush 39 moves downward, the slide rod 40, in conjunction with the moving guide block 37, drives the cleaning brush 39 to move closer to the filter frame 33, so that the cleaning brush 39 abuts against the filter frame 33 and... Dust adhering to the filter frame 33 is swept off, and the top plate set on the cleaning brush 39 pushes open the partition 35. The dust falls along the partition 35 into the inside of the sludge collection box 34. Then, the lifting plate 38 moves upward. At this time, the slide rod 40, together with the moving guide block 37, drives the cleaning brush 39 to move away from the filter frame 33, so that the cleaning brush 39 separates from the filter frame 33. This process is repeated to complete the cyclic cleaning of the filter frame 33. By setting the collaborative cleaning component 11, the cleaning brush 39 can be raised and lowered back and forth, and synchronously extended and retracted during the raising and lowering process, so as to avoid the filter frame 33 from clogging and ensure the stability of the equipment during operation.
