Description

Technical Field

[0001] The invention relates to the technical field of sound attenuation, and in particular to a movable sound attenuation shutter for industrial plants. Background Art

[0002] In high-noise industrial sites such as pump rooms, compressor rooms, and diesel generator rooms, it is usually necessary to use ventilation systems to remove the waste heat generated by equipment operation. These ventilation systems usually use mechanical exhaust and natural air supply through lower rainproof and air supply louvers. However, the existing rainproof and air supply louvers have obvious design defects. Their opening area is fixed and there are no effective sound absorption or sound insulation measures. As a result, noise is easily transmitted to the outdoors through the air supply vents, which not only has adverse effects on the surrounding environment and personnel health, but also may make it difficult for the factory boundary noise level to meet the requirements of environmental protection regulations.

[0003] In the prior art, common sound-absorbing shutters include "herringbone", "V" and "M" structures. These shutters are mainly used to reduce noise at the heat dissipation outlets of equipment, rather than for overall noise control in factories. In addition, most of the current sound-absorbing shutters are fixed in design and cannot be opened and closed according to actual needs. They have a single function and lack flexibility, making it difficult to meet the needs of industrial factory air intakes for noise control under different working conditions.

[0004] Therefore, there is an urgent need for a double-layer sound-absorbing shutter that can realize electric control opening and closing, and is used for the air supply vent design of industrial plants.

[0005] In view of the above problems, the present invention is proposed. Summary of the invention

[0006] The invention discloses a movable sound-absorbing shutter for industrial plants, aiming to solve the technical problems existing in the prior art.

[0007] The present invention provides a movable sound-absorbing shutter for industrial plants, comprising a frame, a shutter part and a driving part, wherein the shutter part and the driving part are both arranged inside the frame;

[0008] The louver part is provided with a plurality of louvers and a plurality of rotating shafts corresponding to the louvers, the louvers are in an inverted V shape, and the rotating shafts are fixedly connected to both sides of the inverted V shape of the louvers;

[0009] The driving part is provided with at least one driving rod, a driver and a controller, the driving rod is bridged with the rotating shaft, the driver is fixedly arranged at the bottom of the driving rod, and the controller is arranged outside and connected with the driver;

[0010] When the driving rod moves up and down along the axis of the driving rod under the control of the driver and the controller, the rotating shaft rotates under the drive of the driving rod and drives the shutters to open and close, so as to provide air supply or silence the industrial plant.

[0011] As a preferred technical solution, the plurality of louvers are evenly distributed along the axial direction of the driving rod.

[0012] As a preferred technical solution, a plurality of rotating shafts are arranged on both sides of the inverted V-shape of the shutter to form two rows, and the straight line direction of the two rows of rotating shafts is parallel to the axial direction of the driving rod.

[0013] As a preferred technical solution, multiple rotating shafts are evenly distributed in a row, and their intervals are equal to the intervals between multiple louvers.

[0014] As a preferred technical solution, the number of rotating shafts is twice the number of louvers.

[0015] As a preferred technical solution, the number of driving rods is 2, and the two driving rods are arranged in parallel.

[0016] As a preferred technical solution, the louvers are arranged in a multi-layer structure.

[0017] As a preferred technical solution, the louver includes a first louver layer, at least one second louver layer, at least one third louver layer and at least one fourth louver layer. The first louver layer is a supporting layer, the second louver layer is a damping layer, the third louver layer is a sound absorbing layer, and the fourth louver layer is a surface protective layer.

[0018] As a preferred technical solution, the multi-layer structure of the louver is 7-13 layers.

[0019] As a preferred technical solution, the frame is provided with a first frame layer, a second frame layer, a third frame layer and a fourth frame layer which are connected in sequence; the fourth frame layer is in contact with the outside and adopts a stainless steel wire mesh; the third frame layer adopts thick glass wool; the second frame layer adopts thick modified asphalt; and the first frame layer adopts stainless steel.

[0020] The technical solution adopted by the present invention can achieve at least one of the following beneficial effects:

[0021] 1. The present invention adopts an inverted V-shaped shutter structure design, combined with the multi-layer structure of the frame and the multi-layer structure of the shutter, so that the movable sound-absorbing shutter can effectively achieve noise control in both the open and closed states. When open, the inverted V-shaped shutter forms a sound-absorbing channel, significantly increases the sound-absorbing length, and can reduce 10-15dB of noise; when closed, the sound insulation effect is more prominent, and 20-30dB of noise can be isolated, effectively preventing noise leakage in the workplace.

[0022] 2. The present invention has a remote control function, which can flexibly adjust the opening and closing state of the blinds according to the production needs of the industrial plant, which is convenient and efficient and improves applicability.

[0023] 3. The shutters of the present invention have a multi-layer structure, which combines the functional characteristics of materials such as the supporting layer, damping layer, sound absorbing layer and protective layer to further improve the sound absorption and sound insulation effects. The multi-layer design is flexible and has a wide range of applications. The frame is composed of multiple layers of high-efficiency sound insulation materials, including stainless steel wire mesh, thick glass wool, modified asphalt and stainless steel, which helps to enhance the stability and sound insulation performance of the overall structure.

[0024] 4. Through the optimized design of the driving rod and the rotating shaft, the opening and closing movement of the shutter is stable and reliable, and the application of materials such as stainless steel and glass wool improves the corrosion resistance and durability of the equipment, making it suitable for long-term use in industrial environments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a movable sound-absorbing shutter for industrial plants, and more particularly, relates to a sound-absorbing shutter for air supply in industrial plants, which can be opened and closed by electric control, such as Figure 1-Figure 4 As shown, it includes a frame 1, a steel plate 2 arranged inside the frame 1, a shutter part 3 and a driving part 4. The cavity part between the frame 1 and the steel plate 2 is used as a window frame, and is partially embedded in the wall of the industrial plant.

[0036] The frame 1 is used to provide support and fixing functions, and also plays the role of sound insulation and sealing. In order to enhance the above effects, Figure 3As shown, the frame 1 includes a first frame layer 11, a second frame layer 12, a third frame layer 13 and a fourth frame layer 14 connected in sequence. The fourth frame layer 14 is arranged at the outermost layer of the frame 1 and is in contact with the outside world. The fourth frame layer 14 is used as a protective surface layer and adopts a stainless steel wire mesh, which is mainly used to protect the internal structure and functional layers (such as sound absorption layer and damping layer) of the frame from erosion and mechanical damage of the external environment, thereby extending the overall service life. The third frame layer 13 is arranged on the inner side of the fourth frame layer 14 and is connected thereto. The third frame layer 13 is a sound absorption layer, which is mainly used to absorb sound wave energy, reduce the reflection and propagation of sound waves inside the frame 1, thereby improving the noise reduction effect of the soundproof shutter. Preferably, the third frame layer 13 adopts thick glass wool, and its thickness is 2-3mm. The second frame layer 12 is arranged on the inner side of the third frame layer 13 and is connected thereto. The second frame layer 12 is a damping layer, which is used to reduce the noise radiation caused by structural vibration, thereby further improving the overall soundproofing effect of the soundproof shutter. In order to enhance the above effect, preferably, the second frame layer 12 is made of thick modified asphalt with a thickness of 5-7 mm. The first frame layer 11 is arranged on the inner side of the second frame layer 12, is a support layer, and is made of stainless steel. Preferably, the thickness of the first frame layer 11 is 2-3 mm.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the louver portion 3 includes a plurality of louvers 31 and a plurality of rotating shafts 32 corresponding to the louvers 31. Figure 2 As shown, the louver 31 is in an inverted V shape, and the angle of the inverted V shape can be adjusted. Two rotating shafts 32 are respectively provided on the corresponding single louver 31, and the two rotating shafts 32 are respectively fixedly connected to the two V-shaped edges of the louver 31. When the rotating shaft 32 rotates, the louver 31 is driven to rotate to adjust the angle of its inverted V shape; the inverted V-shaped angle range is 0°-45°, that is, at 0°, the louver 31 is closed and in a vertical state, forming a double-layer blade structure, and at 45°, the louver 31 opens to the maximum angle. In order to better achieve the above-mentioned adjustment effect, preferably, the number of rotating shafts 32 is twice that of the louver 31. Further preferably, the number of louvers 31 is 9-15; the number of rotating shafts 32 is 18-30. During the design, if the number of louvers 31 is too small, the sound insulation effect cannot be guaranteed. If the number of louvers 31 is too large, the overall structural complexity will be increased, the reliability will be reduced, and the economic cost will be increased.

[0038] The driving unit 4 includes a driving rod 41, a driver 42 and a controller 43. The driving rod 41 is connected to the rotating shaft 32. The driving rod 41 can move up and down in the vertical direction (the axial direction of the driving rod 41) and drive the rotating shaft 32 to rotate. Preferably, there are two driving rods 41, which are arranged in parallel. Figure 2As shown, multiple shutters 31 are evenly spaced along the vertical direction of the driving rod 41 to ensure that the angle and position of each shutter 31 are consistent, so that the entire device moves smoothly when the shutters are opened and closed to avoid uneven force. The apex of the inverted V-shaped of the multiple shutters 31 is on the same vertical line, and the two V-shaped edges are symmetrically distributed along the two sides of the vertical line to maintain the overall balance and stability. The multiple rotating shafts 32 fixedly set on the V-shaped edges on the same side of the multiple shutters 31 are located in the same straight line direction, and the spacing is equal, and the spacing is equal to the spacing between the multiple shutters 31. The multiple rotating shafts 32 located on the V-shaped edges on the same side of the multiple shutters 31 are fixed on the same driving rod 41. When the driving rod 41 moves up and down in the vertical direction, it drives the multiple rotating shafts 32 on the same side to rotate, and the multiple rotating rotating shafts 32 drive the same side of the multiple shutters 31 to rotate, forming a specific inverted V-shaped angle. That is, the plurality of rotating shafts 32 form two rows on both sides of the inverted V-shape of the shutter 32 , and the straight lines of the two rows of rotating shafts are parallel to the axial direction of the driving rod 41 .

[0039] like Figure 2 As shown, a driver 42 is fixedly arranged at the bottom of the driving rod 41, and a controller 43 is arranged in connection with the driver 42. The controller 43 is arranged outside the device (not marked in the figure). The operator remotely operates the controller 43 to control the start of the driver 42. Under the control of the driver 42, the driving rod 41 moves up and down in the vertical direction.

[0040] Through the above-mentioned structural design, when the industrial plant does not need air supply, the operator remotely operates the controller 43 to control the driver 42 to start, and the drive rod 41 moves upward in its vertical direction under the control of the driver 42, and the multiple shafts 32 rotate under the drive of the drive rod 41, and at the same time drive the multiple shutters 31 to rotate into an inverted V-shaped state with both sides closed, that is, both sides of the inverted V-shape of the multiple shutters 31 are in a vertical state. At this time, the entire sound-absorbing shutter is in a closed state and forms a sound insulation structure; when the industrial plant needs air supply, the operator remotely operates the controller 43 to control the driver 42 to start, and the drive rod 41 moves downward in its vertical direction under the control of the driver 42, and the multiple shafts 32 rotate under the drive of the drive rod 41, and at the same time drive the multiple shutters 31 to rotate into an inverted V-shaped state. At this time, the multiple shutters 31 form an inverted V-shape of a certain angle, and the sound-absorbing shutter is in an open state. This structural design drives multiple rotating shafts 32 and shutters 31 to achieve linkage through a driving rod 41, and adjusts the opening and closing state of the shutters according to needs, effectively controlling the air circulation while meeting the air supply demand; the inverted V-shaped design enhances the stability of the shutters, maintaining a certain angle when open, and effectively reducing shaking or damage caused by wind or airflow fluctuations; through the automatic control of the driver 42, it reduces the possibility of accidental touches or accidents during manual operation, thereby improving the safety of equipment operation.

[0041] In some preferred embodiments, in order to increase the sound insulation effect of the louvers 31, the louvers 31 are arranged in a multi-layer structure, including a first louver layer 311, a second louver layer 312, a third louver layer 313 and a fourth louver layer 314. Figure 4 As shown, the multi-layer structure of the louver 31 is set to at least 7 layers. Preferably, the multi-layer structure of the louver 31 is 7-13 layers. The first louver layer 311 is a supporting layer, and is made of stainless steel. Preferably, the thickness of the first louver layer 311 is 2-3mm. The second louver layer 312 is a damping layer, which is used to reduce the noise radiation caused by structural vibration, thereby further improving the overall sound-absorbing effect of the sound-absorbing louver. In order to increase the above effects, preferably, the second louver layer 312 uses thick modified asphalt with a thickness of 5-7mm. The third louver layer 313 is a sound-absorbing layer, which uses thick glass wool with a thickness of 2-3mm. The fourth louver layer 314 is a protective layer, which uses a stainless steel wire mesh. As shown Figure 4 As shown, the center of the louver 31 adopts the first louver layer 311, and the second louver layer 312, the third louver layer 313 and the fourth louver layer 314 are arranged in sequence along the two sides to form a 7-layer structure.

[0042] In some preferred embodiments, the steel plate 2 is in a square hollow shape, such as Figure 1 As shown, the vertical edge of the steel plate 2 is connected to the rotating shaft 32 to provide support therefor.

[0043] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
