[0023] See also Figure 1-5 , an embodiment provided by the utility model:

[0024] A large equipment noise reduction device, comprising:

[0025] The main body includes a sound insulation board 1, a diagonal support stabilizing bracket 11 is fixedly connected to the surface of the sound insulation board 1, a running wheel 12 is arranged on the lower surface of the diagonal support stabilizing bracket 11, and a stainless steel frame 13 is fixedly connected to the top of the sound insulation board 1;

[0026] The docking mechanism includes a first fixing block 2, the first fixing block 2 is fixedly connected to one side of the sound insulation board 1, and the other side of the sound insulation board 1 is fixedly connected to a second fixing block 21, a No. 1 nut 22 is fixedly connected to the surface of the sound insulation board 1, and a No. 1 bolt 23 is threadedly connected to the surface of the No. 1 nut 22, and a No. 2 nut 24 is fixedly connected to the surface of the sound insulation board 1, and a No. 2 bolt 25 is threadedly connected to the surface of the No. 2 nut 24. The docking mechanism can quickly dock multiple groups of sound insulation boards 1 together, thereby reducing the noise of large equipment, ensuring the installation time of the sound insulation board 1, and providing sufficient working time for the use of large equipment.

[0027] Furthermore, a sound insulation mechanism is provided at the bottom of the sound insulation board 1, a guide frame 3 is fixedly connected to the surface of the sound insulation board 1, a sound insulation bottom plate 31 is slidably connected to the surface of the guide frame 3, a No. 3 bolt 32 is threadedly connected to the surface of the sound insulation bottom plate 31, and an anti-skid plate 33 is fixedly connected to the bottom of the sound insulation bottom plate 31. The sound insulation mechanism can soundproof the bottom of the sound insulation board 1, thereby improving the sound insulation effect of the sound insulation board 1.

[0028] Furthermore, two groups of first fixing blocks 2 are provided, and two groups of second fixing blocks 21 are provided. The horizontal height of the second fixing blocks 21 is higher than the horizontal height of the first fixing blocks 2. When two groups of sound insulation boards 1 are docked, the second fixing blocks 21 will be directly above the sound insulation boards 1, thereby facilitating the docking between the sound insulation boards 1.

[0029] Furthermore, a circular hole is opened on the surface of the second fixing block 21, and a circular hole is opened on the surface of the first fixing block 2. The No. 1 bolt 23 penetrates the circular holes of the first fixing block 2 and the second fixing block 21 at the same time, and the No. 2 bolt 25 penetrates the circular holes of the first fixing block 2 and the second fixing block 21 at the same time. The No. 1 bolt 23 limits one side of the two groups of sound insulation boards 1 through the first fixing block 2 and the second fixing block 21, and the No. 2 bolt 25 limits the other side of the second fixing block 21 through the first fixing block 2 and the second fixing block 21, thereby completing the position limitation between the two groups of sound insulation boards 1.

[0030] Furthermore, the horizontal heights of the No. 2 nut 24 and the No. 1 nut 22 are the same and lower than the first fixing block 2 and the second fixing block 21. The No. 1 nut 22 and the No. 2 nut 24 are staggered on the sound insulation board 1, ensuring that both sides of the sound insulation board 1 can be docked, thereby improving the stability of the docking of the sound insulation board 1.

[0031] Furthermore, a guide groove is opened on the surface of the guide frame 3, and the sound insulation bottom plate 31 is in an "L" shape. The sound insulation bottom plate 31 slides on the guide groove of the guide frame 3. During the sliding process, the sound insulation bottom plate 31 will drive the anti-skid plate 33 to slide, and the anti-skid plate 33 will eventually slide to the ground. The anti-skid plate 33 increases the friction with the ground. The sound insulation bottom plate 31 can soundproof the sound insulation board 1 and the ground, thereby improving the overall sound insulation effect of the sound insulation board 1.

[0032] Furthermore, two groups of threaded grooves are opened on the surface of the sound insulation base plate 31, and a circular hole is opened on the surface of the guide frame 3. The No. 3 bolt 32 passes through the circular hole of the guide frame 3 and one group of threaded grooves of the sound insulation base plate 31 for threaded connection. When the sound insulation base plate 31 cannot slide downward on the guide frame 3, the circular hole of the guide frame 3 is aligned with the threaded groove at the top of the sound insulation base plate 31. When the sound insulation base plate 31 cannot slide upward, the circular hole of the guide frame 3 is aligned with the threaded hole of the sound insulation base plate 31.

[0033] Working principle: The sound insulation board 1 is moved by the walking wheel 12 at the bottom of the diagonal support stabilizing bracket 11, and the side edges of the two groups of sound insulation boards 1 are contacted and connected together. At this time, the second fixing block 21 will move to the top of the first fixing block 2, and the No. 1 nut 22 will move to the bottom of the first fixing block 2 and the second fixing block 21. At this time, the No. 1 bolt 23 is rotated on the No. 1 nut 22, so that the No. 1 bolt 23 passes through the first fixing block 2 and the second fixing block 21, and then the No. 2 bolt 25 is rotated on the No. 2 nut 24, so that the No. 2 bolt 25 passes through the first fixing block 2 and the second fixing block 21, thereby completing the docking work of the two groups of sound insulation boards 1 near large equipment.

[0034] The No. 3 bolt 32 is rotated on the threaded groove at the top of the sound insulation base plate 31, and the No. 3 bolt 32 is removed from the sound insulation base plate 31, so that the sound insulation base plate 31 can slide on the guide frame 3. When the sound insulation base plate 31 cannot slide downward on the guide frame 3, the anti-slip plate 33 is in contact with the ground. Then the No. 3 bolt 32 is passed through the circular hole of the No. 3 bolt 32 and is threadedly connected with the threaded groove at the bottom of the sound insulation base plate 31 to limit the position of the sound insulation base plate 31 on the guide frame 3, thereby limiting the position of the sound insulation base plate 31 at the bottom of the sound insulation board 1. The sound insulation base plate 31 insulates the bottom of the sound insulation board 1 from the ground, thereby improving the sound insulation effect of the sound insulation board 1.
