[0021] Example 1

[0022] like Figure 1-4 The figure shows the first embodiment of the utility model, which provides a noise reduction device for mine blasting, including a noise reduction unit 1. The noise reduction unit 1 includes a steel plate box 11, and a buffer assembly 2 is provided on the back of the steel plate box 11. Both ends of the steel plate box 11 are fixedly connected with connecting plates 3, one side of the right end connecting plate 3 is fixedly connected with a clamping strip 5, and one side of the left end connecting plate 3 is fixedly connected with a clamping seat 4. The inner cavity of the steel plate box 11 is respectively provided with a concrete plate 12, a glass fiber board 13, a plastic board 14 and a sound-absorbing cotton board 15. The buffer assembly 2 includes a movable plate 21, one side of the movable plate 21 is fixedly connected with a spring 22, and the other end of the spring 22 is fixedly connected to the steel plate box 11, and the back of the steel plate box 11 is fixedly connected with a damper 23, and the other end of the damper 23 is fixedly connected to the movable plate 21.

[0023] like Figure 1-4As shown, the connecting plate 3 or the card strip 5 enters the inner cavity of the card seat 4 to achieve card connection, and then multiple steel plate boxes 11 can be spliced, so that the mine blasting location can be enclosed, and the blasting impact force can be resisted by the spring 22, and the impact force will drive the movable plate 21 to squeeze the spring 22 and the damper 23, thereby causing the spring 22 and the damper 23 to deform, thereby buffering the impact force. At the same time, the reset elastic force of the spring 22 and the damper 23 can drive the movable plate 21 to reset, thereby buffering and offsetting the impact force generated by the blasting. When the blasting sound wave is transmitted to the steel plate box 11, the steel plate box 11 initially resists the noise generated by the blasting, and the concrete plate 12 can block the sound wave, and the fiberglass board 13 and the plastic board 14 can rebound the sound wave, making it difficult for the sound wave to transmit outward. The remaining sound waves can be absorbed by the sound-absorbing cotton board 15, thereby effectively achieving the noise reduction effect and preventing the noise from being transmitted outward to interfere with the lives of nearby residents.

[0024] Example 2

[0025] Reference Figure 1-4 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the concrete slab 12 is located at the rear end of the inner cavity of the steel plate box 11, and the fiberglass board 13 is located at the front end of the concrete slab 12, the plastic board 14 is located at the front end of the fiberglass board 13, and the sound-absorbing cotton board 15 is located at the front end of the plastic board 14, and one end of the connecting plate 3 and the card strip 5 extends to the inner cavity of the card seat 4 and is movably connected to the inner cavity of the card seat 4.

[0027] A bolt 6 is threadedly connected to one side of the base 4, and a positioning hole 7 is opened on one side of the connecting plate 3 and the clamping strip 5. One end of the bolt 6 extends to the inner cavity of the positioning hole 7 and is threadedly connected to the inner cavity of the positioning hole 7.

[0028] Both ends of the movable plate 21 are fixedly connected to the limiting strips 211 . A limiting slot 311 is defined on one side of the connecting plate 3 . The limiting strip 211 is located in the inner cavity of the limiting slot 311 and is movably connected to the inner cavity of the limiting slot 311 .

[0029] like Figure 1-4 As shown, when the movable plate 21 receives the impact force and moves, it can drive the limit bar 211 to slide along the inner cavity of the limit groove 311, thereby limiting the movable plate 21 to prevent the movable plate 21 from being dislocated during movement. At the same time, the connecting plate 3 or the card strip 5 enters the inner cavity of the card seat 4 to achieve card connection, and the bolt 6 rotates while moving to one side and gradually enters the inner cavity of the positioning hole 7, thereby realizing the positioning and fixation of the connecting plate 3 and the card strip 5 and the card seat 4, so that multiple steel plate boxes 11 can be spliced.

[0030] Example 3

[0031] Reference Figure 3 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0032] In this embodiment, a warning component 8 is provided on the front of the steel plate box 11. The warning component 8 includes a warning plate 81. The front of the warning plate 81 is provided with a warning sheet and a reflective strip.

[0033] The back of the warning plate 81 is fixedly connected with a magic tape 82, and the front of the steel box 11 is fixedly connected with a magic tape 83. The magic tape 83 and the magic tape 82 are bonded to each other at their adjacent sides.

[0034] like Figure 3 As shown, the warning piece on the warning plate 81 can remind people of dangerous construction sites and prevent them from approaching. At the same time, the reflective strip can reflect light at night to remind people of danger at night. The warning plate 81 drives the Velcro 82 and the Velcro 83 to adhere to each other, thereby fixing the warning plate 81.

[0035] When in use, first enter the inner cavity of the card seat 4 through the connecting plate 3 or the card strip 5 to achieve card connection, and then rotate the bolt 6. The bolt 6 moves to one side while rotating and gradually enters the inner cavity of the positioning hole 7, thereby realizing the positioning and fixation of the connecting plate 3 and the card strip 5 and the card seat 4. Multiple steel plate boxes 11 can be spliced ​​together, which is convenient for fencing the mine blasting position. The blasting impact force can be resisted by the spring 22, and the impact force will drive the movable plate 21 to squeeze the spring 22 and the damper 23, thereby causing the spring 22 and the damper 23 to deform, thereby achieving the buffering of the impact force. At the same time, the restoring elastic force of the spring 22 and the damper 23 can drive the movable plate 21 to reset, thereby buffering and offsetting the impact force generated by the blasting. When the blasting sound wave is transmitted to the steel plate box 11, the steel plate box 11 initially resists the noise generated by the blasting, and the concrete plate 12 can block the sound wave, and the fiberglass plate 13 and the plastic plate 14 can rebound the sound wave, making it difficult for the sound wave to transmit outward, and the remaining sound waves can be absorbed by the sound-absorbing cotton board 15, thereby effectively achieving the effect of noise reduction and preventing the noise from transmitting outward and interfering with the lives of nearby residents.
