The first inclined surface and the second inclined surface enable the blocking block to be stuck in the blocking groove, thereby completing the fixation of the adjacent fixed plates; the second rubber layer ensures the sound insulation tightness of the adjacent fixed plates; when dismantling, push the push plate to move the blocking block upward, and the blocking block will be out of the blocking groove, so that the adjacent fixed plates can be separated.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 13As shown, the noise reduction and isolation mechanism for engineering construction described in the present invention includes a fixing plate 1, a first through groove 11 is vertically opened in the middle of the fixing plate 1, a first groove 14 is opened at the top of the fixing plate 1, a two-way threaded column 15 is rotatably connected to the middle of the bottom end of the first through groove 11, the top of the two-way threaded column 15 passes through the fixing plate 1 and extends into the first groove 14, a nut is fixed to the top of the two-way threaded column 15, a first threaded groove 18 is opened on the nut, a limiting hole 191 is opened at the bottom end of the first groove 14, a first threaded column 19 is threadedly connected to the first threaded groove 18, and two locking nut are slidably connected in the first through groove 11. The first expansion plate 12 and the second expansion plate 13 are symmetrically distributed on the bidirectional threaded column 15. The bidirectional threaded column 15 is connected to two sliding plates 16 through a screw nut pair. The sliding plate 16 is slidably connected to the first through groove 11. The sliding plate 16 is hinged to the side wall of the first expansion plate 12 and the side wall of the second expansion plate 13 respectively through two hinge rods 17. The first expansion plate 12 and the second expansion plate 13 are convex. After the first expansion plate 12 and the second expansion plate 13 are pushed out of the first through groove 11, both of them seal the space between the adjacent side walls of the first expansion plate 12 and the second expansion plate 13 through a seal, and the fixed plate 1 side wall is provided with a vacuum warning component, which vacuums the space between the adjacent side walls of the first expansion plate 12 and the second expansion plate 13. The first expansion plate 12 and the second expansion plate 13 are both provided with two first cavities 192. When in use, the nut is rotated by an electric nut gun to drive the bidirectional threaded column 15 to rotate, and the two sliding plates 16 to move toward each other, and the first expansion plate 12 and the second expansion plate 13 are driven to extend out of the first through slot 11 through the hinge rod 17, thereby adjusting the size of the entire fixed plate 1. At the same time, under the same volume of plate material, the coverage area is increased, and the first expansion plate 1 2 and the second expansion plate 13 are expanded, the space between the adjacent surfaces of the first expansion plate 12 and the second expansion plate 13 forms a sealed cavity under the action of the seal, and the first expansion plate 12 and the second expansion plate 13 are both provided with a first cavity 192, which can reflect sound waves and reflect them back to the direction of the sound source to achieve the purpose of canceling noise; during construction, some equipment has a relatively high noise level, and the fixed plate 1 uses the vacuum warning component to vacuum the cavity between the adjacent surfaces of the first expansion plate 12 and the second expansion plate 13, and uses the near-vacuum environment to increase the sound insulation effect of the fixed plate 1, which can be targeted and applied to different noise environments.

[0039] The vacuum warning component includes an exhaust pipe 2 and a fixed cylinder 22. The exhaust pipe 2 is fixedly connected to the side wall of the fixed plate 1. The exhaust pipe 2 is communicated with the first through groove 11. The exhaust pipe 2 is located on the vertical center line of the first through groove 11. A switch valve 21 is installed on the exhaust pipe 2. The fixed cylinder 22 is fixedly connected to the side wall of the fixed plate 1. An elastic air bag 23 is provided in the fixed cylinder 22. One end of the elastic air bag 23 is communicated with the first through groove 11. The position of the fixed cylinder 22 and the center of the first through groove 11 coincide with each other. An indicator column 24 is fixedly connected to one end of the elastic air bag 23. The indicator column 24 passes through the fixed cylinder 22 and is provided with a fluorescent layer 25. When working, when it is necessary to increase the noise reduction effect in a targeted manner, a vacuum pump is used to connect the exhaust pipe 2 through a pipeline for vacuuming. During the vacuum operation, the first through groove 11 remains sealed under the action of the sealing member. When the air is extracted, the elastic airbag 23 is sucked flat, thereby driving the indicator column 24 to shrink and enter the fixed tube 22 (at this time, the fluorescent layer 25 of the indicator column 24 will also enter the fixed tube 22, and the fluorescent layer 25 will not leak out of the fixed tube 22, indicating that the fixed plate 1 is in a vacuum state). After the vacuum is exhausted, the noise is effectively reduced. At the same time, after the switch valve 21 is closed, the vacuum state in the first through groove 11 is maintained (approximately vacuum, and the sealing member cannot be completely sealed, and air will slowly enter). Because after air enters the first through groove 11, the elastic airbag 23 will expand, push out the indicator column 24, and after the fluorescent layer 25 is exposed, it indicates that the noise reduction state is normal.

[0040] The sealing member includes a meandering groove 3, which is symmetrically provided on the first deployment plate 12 and the second deployment plate 13. A meandering rubber layer 31 is fixedly connected to the meandering groove 3. The inside of the meandering rubber layer 31 is hollow, and the meandering rubber layer 31 is inflated by the inflation unit. During operation, the first deployment plate 12 and the second deployment plate 13 are in an open state, and the meandering rubber layer 31 in the meandering groove 3 is inflated by the inflation unit, so that the meandering rubber layer 31 is tightly attached to the inner wall of the first through groove 11, forming a sealed cavity between the adjacent surfaces of the first deployment plate 12 and the second deployment plate 13. On the one hand, the cavity is formed for normal noise reduction, and on the other hand, it is convenient for subsequent vacuuming operations.

[0041] The inflation unit includes an extrusion plate 34. Second grooves 32 are provided on the upper and lower side walls of the first deployment plate 12 and the second deployment plate 13. Two symmetrically distributed extrusion plates 34 are fixedly connected to the upper and lower side walls of the first through groove 11. The extrusion plates 34 are slidably connected in the second grooves 32. An airbag 33 is fixed between the side walls of the second groove 32 and the side walls of the extrusion plates 34. The airbag 33 is connected to the inner cavity of the circular rubber layer 31 through a hose. During operation, when the first deployment plate 12 and the second deployment plate 13 are in the deployed state, the extrusion plates 34 squeeze the airbag 33, allowing the gas in the airbag 33 to be filled into the inner cavity of the circular rubber layer 31, causing it to expand and complete the sealing operation.

[0042] Two symmetrically distributed third grooves 4 are provided on the side wall of the first deployment plate 12, and a sliding block 41 is fixed to the bottom of the third groove 4 by a spring. The sliding block 41 is slidably connected to the third groove 4, and a locking groove 42 is provided on the side of the two sliding blocks 41 away from each other. A first inclined surface 48 is provided on the side wall of the sliding block 41 away from the bottom of the third groove 4. Two symmetrically distributed fourth grooves 43 are provided on the side wall of the second deployment plate 13, and the positions of the third groove 4 and the fourth groove 43 correspond to each other. A fifth groove 44 is provided on the side of the two fourth grooves 43 away from each other, and a locking block 45 is fixed to the bottom of the fifth groove 44 by a spring. A second inclined surface 49 is provided on the side wall of the locking block 45 away from the bottom of the fourth groove 43. The first inclined surface 48 and the second inclined surface 49 are parallel to each other. A second through groove 46 is provided on the side wall of the second deployment plate 13, and the second through groove 46 and the fifth groove 44 is connected, and a push plate 47 is slidably connected in the second through groove 46. The push plate 47 is fixed on the locking block 45, and the sliding block 41 is limited in the third groove 4 by the positioning member. The side walls of the first expansion plate 12 and the second expansion plate 13 are fixed with the second rubber layer 491; when working, when the adjacent fixed plate 1 is fixedly installed to form a barrier, the positioning member is released from the fixing of the sliding block 41, and the sliding block 41 partially extends out of the third groove 4 under the action of the spring force and extends into the fourth groove 43 of the adjacent second expansion plate 13. The locking block 45 is locked in the locking groove 42 through the first inclined surface 48 and the second inclined surface 49, completing the fixation of the adjacent fixed plate 1. The second rubber layer 491 ensures the sound insulation tightness between the adjacent fixed plates 1. When it needs to be removed, push the push plate 47 to move the locking block 45 upward, so that the locking block 45 is separated from the locking groove 42, and the adjacent fixed plates 1 can be separated.

[0043] The positioning member includes a positioning groove 5 and a sixth groove 51. The top of the sliding block 41 is provided with a positioning groove 5. The positioning groove 5 is located behind the positioning groove 42. The third groove 4 and the second groove 32 are partially connected. The adjacent surfaces of the two extrusion plates 34 are provided with a sixth groove 51. The bottom of the sixth groove 51 is fixed with a positioning block 52 by a spring. The positioning block 52 is moved by the pushing unit. The side wall of the positioning block 52 away from the bottom of the third groove 4 is provided with a third inclined surface 53. The side wall of the sliding block 41 close to the bottom of the third groove 4 is provided with a fourth inclined surface 54. The third inclined surface 53 and the fourth inclined surface 54 are parallel to each other. When the plate 1 is not in use, the first unfolding plate 12 and the second unfolding plate 13 are retracted in the first through groove 11. In order to prevent the sliding block 41 from extending out of the third groove 4, a positioning block 52 and a positioning groove 5 are provided. When the fixed plate 1 is transported or stored, the sliding block 41 is manually pushed completely into the third groove 4, and the positioning block 52 is stuck in the positioning groove 5. When the first unfolding plate 12 and the second unfolding plate 13 are in the open state, the positioning block 52 moves up and out of the positioning groove 5 under the action of the pushing unit, releasing the state of the sliding block 41 positioned in the third groove 4, allowing the sliding block 41 to extend to complete the fixation of the adjacent fixed plate 1.

[0044] The pushing unit includes a third through slot 55. Third through slots 55 are provided on both side walls of the extrusion plate 34 in the second groove 32 on the first deployment plate 12. The third through slots 55 are connected to the sixth groove 51. Track slide grooves 57 are provided on both side walls of the second groove 32 on the first deployment plate 12. The track slide grooves 57 in the two second grooves 32 on the first deployment plate 12 are symmetrically arranged. A sliding column 56 is slidably connected in the third through slot 55. One end of the sliding column 56 is slidably connected in the track slide groove 57, and the other end of the sliding column 56 is fixed to the side wall of the positioning block 52. The track slide groove 57 includes a vertical slot 58, a first oblique slot 59 and a horizontal slot 591. The first oblique slot 59 is located between the vertical slot 58 and the horizontal slot 591. One end of the vertical slot 58 close to the bottom of the second groove 32 is connected to the end of the first oblique slot 59 close to the bottom of the second groove 32. The other end of the first oblique slot 59 is connected to the horizontal slot 591. When the first and second unfolding plates 12 and 13 are in the state of being connected, the distance from the horizontal groove 591 to the bottom of the second groove 32 is greater than the distance from the bottom end of the vertical groove 58 to the bottom end of the second groove 32; when working, when the first unfolding plate 12 and the second unfolding plate 13 extend out of the first through groove 11, the sliding post 56 on the positioning block 52 moves in the track slide groove 57, and the sliding post 56 enters the horizontal groove 591 through the first inclined groove 59 at the end of the vertical groove 58 close to the bottom end of the second groove 32, and moves the positioning block 52, thereby disengaging from the positioning groove 5 and releasing the positioning of the sliding block 41; when storing or transporting the fixed plate 1, the first unfolding plate 12 and the second unfolding plate 13 are retracted in the first through groove 11, the sliding post 56 is located at the end of the vertical groove 58 close to the bottom end of the second groove 32, and then the sliding block 41 is manually pushed. Under the action of the third inclined surface 53 and the fourth inclined surface 54, the sliding block 41 allows the positioning block 52 to be stuck in the positioning groove 5, completing the storage of the sliding block 41.

[0045] The two third grooves 4 are provided with a seventh groove 6 on the side away from each other, and the bottom of the seventh groove 6 is fixed with a stopper 61 through a spring, and a first slide groove 62 is provided on the side wall of the second groove 32, and the first slide groove 62 is connected to the seventh groove 6, and a moving block 63 is fixed on the stopper 61, and the moving block 63 extends into the second groove 32 through the first slide groove 62, and a fifth inclined surface 64 is provided on the side wall of the bottom end of the moving block 63, and a push rod 65 is fixed on the side wall of the extrusion plate 34, and the push rod 65 and the fifth inclined surface 64 are relative to each other, and the width of the stopper 61 is greater than the width of the positioning groove 42 and the positioning groove 5; when working, the width of the stopper 61 is greater than the width of the positioning groove 42 and the positioning groove 5, and the stopper 61 cannot enter the positioning groove 42 and the positioning groove 5 When the sliding block 41 is extended out of the third groove 4, the stopper 61 moves down to block the retraction of the sliding block 41, and provides a resisting force when the sliding block 41 is extended into the fourth groove 43, and the stopper 45 is snapped into the stopper groove 42 to avoid the situation where the installation is not in place; when the sliding block 41 is subsequently stored, the first expansion plate 12 and the second expansion plate 13 are first retracted into the first through groove 11, and the push rod 65 moves by pushing the moving block 63, allowing the stopper 61 to retract into the seventh groove 6 without affecting the retraction of the sliding block 41.

[0046] The bottom end of the fixed plate 1 is fixed with a circular block 7, and a threaded hole 73 is provided on the side wall of the circular block 7. A second threaded groove 71 is provided on the side wall of the fixed plate 1. The second threaded groove 71 is connected to the first groove 14. A second threaded column 72 is connected to the second threaded groove 71. Two pairs of third threaded grooves are provided at the bottom end of the fixed plate 1. A detachable universal wheel is provided in the third threaded groove. When a set of fixed plates 1 are stacked up and down, a blocking block 76 is placed in the second groove 32 on the unfolded first unfolding plate 12 and the second unfolding plate 13. , the upper and lower surfaces of the fixed plate 1 are fixedly connected with a third rubber layer 77; in special construction environments, it is sometimes necessary to stack the fixed plates 1, so a circular block 7 is provided. When the fixed plates 1 are stacked, the second threaded column 72 is used for installation, and a third rubber layer 77 is provided to ensure tight fit; there will be a large gap when the first unfolding plate 12 and the second unfolding plate 13 are superimposed, so a blocking block 76 is provided to ensure the sealing of the fixed plates 1 stacked up and down. When multiple fixed plates 1 are set up as horizontal enclosures, universal wheels are installed at the bottom for easy movement.

[0047] A method for operating a noise reduction and isolation mechanism for engineering construction comprises the following steps:

[0048] S1: Rotate the bidirectional threaded column 15, and through the two sliding plates 16 moving toward each other, the hinge rod 17 drives the first expansion plate 12 and the second expansion plate 13 to extend out of the first through slot 11, thereby adjusting the size of the entire fixed plate 1;

[0049] S2: After the first and second deployment plates 12 and 13 are deployed, the positioning member is released from the fixing of the sliding block 41. The sliding block 41 is allowed to partially extend out of the third groove 4 under the action of the spring force and extend into the fourth groove 43 of the adjacent second deployment plate 13. The first and second inclined surfaces 48 and 49 allow the locking block 45 to be locked into the locking groove 42, thus completing the fixing of the adjacent fixed plates 1.

[0050] S3: During removal, the push plate 47 is pushed to move the blocking block 45 upwards, so that the blocking block 45 is disengaged from the blocking groove 42 , thereby completing the separation of the adjacent fixing plates 1 .

[0051] Working principle:

[0052] During use, the nut is rotated by an electric nut gun, driving the bidirectional threaded column 15 to rotate and driving the two sliding plates 16 to move toward each other. The first expansion plate 12 and the second expansion plate 13 are driven to extend out of the first through slot 11 by the hinge rod 17, thereby adjusting the size of the entire fixed plate 1. At the same time, the coverage area is increased under the same volume of plate material. After the first expansion plate 12 and the second expansion plate 13 are expanded, the space between the adjacent surfaces of the first expansion plate 12 and the second expansion plate 13 forms a sealed cavity under the action of the sealing member. At the same time, a first cavity 192 is opened in the first expansion plate 12 and the second expansion plate 13. The cavity can reflect sound waves and reflect them back to the direction of the sound source, thereby achieving the purpose of canceling noise. During construction, some machines and equipment make loud noises, so the surrounding fixed plate 1 uses the vacuum warning component to vacuum the cavity between the adjacent surfaces of the first expansion plate 12 and the second expansion plate 13, creating a nearly vacuum space, thereby increasing the sound insulation effect of the fixed plate 1 and being suitable for different noise environments. When it is necessary to increase the noise reduction effect in a targeted manner, the existing vacuum pump is used to connect the exhaust pipe 2 through the pipeline for vacuuming. Because the first through groove 11 is in a sealed state under the action of the sealing member, the elastic airbag 23 is in a vacuum state during vacuuming. The indicator column 24 is sucked flat, and the fluorescent layer 25 of the indicator column 24 also enters the fixed tube 22. The fluorescent layer 25 does not leak out of the fixed tube 22, indicating that the fixed plate 1 is in a vacuum state. After vacuuming, the noise is effectively reduced. At the same time, after closing the switch valve 21, the vacuum state in the first through groove 11 will be maintained (similar to vacuum, and the seal cannot be completely sealed, and air will slowly enter). After air enters the first through groove 11, the elastic airbag 23 expands, pushing the indicator column 24 out, exposing the fluorescent layer 25, indicating that it is in a normal noise reduction state, indicating that the fixed plate 1's working state; when the adjacent fixed plates 1 are fixedly installed to form a fence, the positioning piece releases the fixation of the sliding block 41, and the sliding block 41 partially extends out of the third groove 4 under the action of the spring force, and extends into the fourth groove 43 of the adjacent second unfolding plate 13, and the first inclined surface 48 and the second inclined surface 49 allow the blocking block 45 to be stuck in the blocking groove 42 to complete the fixation of the adjacent fixed plates 1; the second rubber layer 491 ensures the sound insulation tightness when the adjacent fixed plates 1 are fixed; when dismantling, push the push plate 47 to move the blocking block 45 upwards, so that the blocking block 45 is disengaged from the blocking groove 42, and the fixed plate 1 can be separated.
