Description

Technical Field

[0001] The invention relates to the technical field of air compressor noise reduction, in particular to an integrated sound insulation cover. Background Art

[0002] The noise generated by the air compressor during operation mainly comes from mechanical vibration, airflow fluctuations and resonance phenomena during its operation. These noises not only affect the health of operators, but also interfere with the surrounding environment. Therefore, effective noise control measures become particularly important. Soundproof enclosures, as a common noise suppression device, can significantly reduce noise propagation by isolating the air compressor from the external environment.

[0003] Currently, there are many sound insulation enclosure products on the market, which usually use lightweight structural materials with high transmission loss capacity to block the propagation of sound waves. A common practice is to add rib structures to the metal plate surface, or coat its surface with damping materials to suppress the sound wave radiation caused by resonance and vibration. In addition, the inside of the sound insulation enclosure can be treated with sound-absorbing materials or special acoustic designs to further reduce the noise level inside the enclosure. However, the air compressor needs to dissipate heat through ventilation during operation. The higher the heat generated, the greater the noise leaked as the ventilation volume increases. Therefore, it is particularly important to balance the relationship between noise reduction and ventilation.

[0004] The existing Chinese patent application with publication number CN102434498A discloses an air compressor soundproof enclosure, including a soundproof enclosure body, the soundproof enclosure body is sleeved on a support frame, an air compressor is arranged on the support frame inside the soundproof enclosure body, a buffer component is arranged between the air compressor and the support frame, an air inlet is arranged on one side of the soundproof enclosure body, an air inlet silencer is arranged on the air inlet, a muffler box is arranged on the top of the soundproof enclosure body, an air outlet is arranged on the top of the muffler box, an air outlet silencer is arranged on the air outlet, an axial flow fan is arranged inside the muffler box at the air outlet, a sound absorbing lining is arranged on the inner wall of the soundproof enclosure body, a muffler filler is arranged in the muffler box, and a sealing ring is arranged between the soundproof enclosure body and the support frame. The advantages of this invention are: after installing the soundproof enclosure, the noise emitted by the air compressor can meet environmental protection requirements, and troubleshooting is convenient, which fundamentally solves the problem of air compressor noise disturbing the public; However, when the above technical solution is in use, it is impossible to control the position movement of the air inlet and the air outlet, so that when the heating area changes, the ventilation and heat dissipation effect is not good, and accurate ventilation cannot be performed according to the heat distribution, which leads to an increase in the air volume required for heat dissipation, and further leads to a deterioration in the sound insulation effect. Therefore, a soundproof enclosure with integrated ventilation control function is required. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides an integrated sound insulation cover, including an air compressor 100, a shell 200, an adjustment mechanism and an outlet noise reduction mechanism. By adjusting the position of the adjustment frame 302, the position of the air vent 1004 is moved to achieve precise cooling of the area of ​​the air compressor 100, reduce the air volume required for cooling, avoid the weakening of the sound insulation effect caused by excessive air volume, and circulate air through multiple air intake ports 2001 to enhance the internal gas fluidity and improve the overall cooling effect.

[0033] Specifically, it includes: an air compressor 100; The shell 200 has two layers, and is mounted on the outside of the air compressor 100 to isolate it from the outside. A cavity 301 is provided between the two layers of the shell 200. An air inlet 201 is provided above the shell 200. Cold air enters the cavity 301 through the air inlet 201 to cool the air compressor 100 and absorb heat. The regulating mechanism includes a cavity 301, in which a regulating frame 302 is slidably arranged. When the regulating frame 302 slides in the cavity 301, the position where the cold air enters the air compressor 100 from the cavity 301 is controlled to change; The outlet noise reduction mechanism includes a transition chamber 401. The transition chamber 401 is provided in the cavity 301. The hot air after absorbing heat is discharged through the transition chamber 401 with noise reduction and noise isolation.

[0034] Among them, the shell 200 includes an inner shell 1001 and an outer shell 1002, the outer shell 1002 and the transition chamber 401 are penetrated with an air outlet 1003, the inner shell 1001 is provided with air holes 1004 at equal intervals, and the adjustment frame 302 is also provided with air holes 1004 at increasing intervals, and the cavity 301 is filled with elastic composite sound insulation material.

[0035] Preferably, the composite sound insulation material has three layers. The outer layer is made of high-density polyethylene HDPE, which provides excellent sound insulation performance while being weather-resistant and waterproof. The middle layer uses rock wool material with a high sound absorption coefficient to absorb sound waves in a specific frequency band and reduce resonance. The inner layer is made of high-temperature resistant and fire-resistant mineral wool to ensure safety and performance when the air compressor is running at 100 high temperatures.

[0036] Preferably, the upper half of the shell 200 is semicircular, and the lower half is rectangular. A circular array of air holes 1004 is opened in the upper half of the inner shell 1001. Two air inlets 201 are also provided and symmetrically arranged in the upper half of the outer shell 1002. The air inlet 201 is directly connected to the cavity 301, thereby transmitting cold air to the inside of the cavity 301.

[0037] Preferably, in this embodiment, the air holes 1004 on the inner shell 1001 are distributed in an array with equal spacing of 20 cm, and the air holes 1004 on the adjustment frame 302 are arranged in an arithmetic progression with a starting distance of 20 cm and increasing by 5 cm each time, so that whenever the adjustment frame 302 slides 5 cm in the cavity 301, only one air hole 1004 on the adjustment frame 302 coincides with the air hole 1004 on the inner shell 1001, so that the position where the gas on the cavity 301 is blown into the air compressor 100 moves by 0.05 m.

[0038] Preferably, the adjustment frames 302 are interlocked and spliced ​​with each other and slide synchronously in the cavity 301, so as to adjust the position of the cold air entry point according to the distribution of the heating area of ​​the air compressor 100, achieve precise cooling, and prevent the sound insulation effect from being weakened due to large flow of gas in and out.

[0039] Among them, an air inlet 2001 is provided at one end of the transition chamber 401 close to the inner shell 1001, and a curtain 2002 is rotatably provided on the inner wall of the air inlet 2001. In the initial state, the curtain 2002 is sealed and embedded with the inner wall of the air inlet 2001 under the action of gravity.

[0040] More preferably, an isolation plate 2003 is horizontally provided in the transition chamber 401, and a push-pull plate 2004 is provided between the isolation plate 2003 and the inner wall of the transition chamber 401, and the push-pull plate 2004 is driven by a push-pull rod to slide back and forth vertically along the isolation plate 2003.

[0041] The push-pull rod is controlled by a cylinder to make the push-pull plate 2004 swing back and forth. The cylinder and the air inlet 201 are connected in parallel to the same air pipe, so that the reciprocating swing rate of the push-pull plate 2004 is synchronously adjusted with the air intake rate of the air inlet 201.

[0042] Furthermore, an air intake port 2001 is provided on each side of the push-pull plate 2004 , and the push-pull plate 2004 always reciprocates in the middle area between the two air intake ports 2001 .

[0043] Among them, Figure 7 The isolation plate 2003 is located at both ends of the push-pull plate 2004 and has through grooves 2005 . A gate plate 2006 is rotatably provided at one end of the isolation plate 2003 near the air outlet 1003 .

[0044] Among them, the curtain 2002 can only be opened toward the transition chamber 401 from the initial state, and the gas outlet 1003 is opened in the area of ​​the transition chamber 401 below the isolation plate 2003, so that the gas can only flow out from below the isolation plate 2003.

[0045] More preferably, the gate plate 2006 is rotatably arranged on the inner wall of the air outlet 1003, and the gate plate 2006 is sealed and engaged with both sides of the inner wall of the air outlet 1003 when the rotation angle is minimum and maximum respectively, and a sound insulation filter material is arranged in the transition chamber 401 to reduce the noise of the discharged gas.

[0046] Preferably, the two sides of the transition chamber 401 are sealed with the inner shell 1001 and the outer shell 1002 respectively, so that the hotter exhaust gas cannot enter the cavity 301, and the gate 2006 and the curtain 2002 have opposite switching states, so that the air compressor 100 is always isolated from the outside world to avoid weakening the sound insulation effect during exhaust.

[0047] In summary, when in use, the cooling gas enters the cavity 301 through the air inlet 201, and is sprayed to the corresponding area of ​​the air compressor 100 along the air holes 1004 on the adjustment frame 302 that coincide with the inner shell 1001, thereby ensuring precise cooling while ensuring the sound insulation effect. At the same time, the temperature of each area inside the inner shell 1001 is detected by a sensor, the internal temperature distribution is obtained, and the movement of the adjustment frame 302 is regulated until the adjustment frame 302 in the higher temperature area coincides with the air holes 1004 of the inner shell 1001, so that the cooling gas is sprayed out from this area, thereby achieving precise cooling of this area of ​​the air compressor 100, reducing the air volume required for cooling, and avoiding the weakening of the sound insulation effect due to excessive air volume.

[0048] At the same time, the cooling gas drives the cylinder and the push-pull rod to move back and forth at the same frequency, so that the push-pull plate 2004 moves back and forth. When the push-pull plate 2004 moves to the left, the curtain 2002 in the air inlet 2001 on the left is sealed with the inner wall due to the increase in air pressure, and the curtain 2002 in the air inlet 2001 on the right rotates outward and detaches from the air inlet 2001 due to the decrease in air pressure. The cooled gas enters the transition chamber 401 through the air inlet 2001, and at the same time, the gas on the right enters the bottom of the isolation plate 2003 along the through groove 2005 The push-pull plate 2004 moves in the opposite direction, and the right side gas blows the gate plate 2006 to rotate leftward through the through groove 2005 on the right side of the push-pull plate 2004 and is discharged from the gas outlet 1003, thereby realizing the active suction and discharge of the gas inside the soundproof enclosure at the same time. This reciprocating process improves the gas exchange rate while ensuring the sound insulation effect. At the same time, multiple air inlets 2001 evenly inhale air, which enhances the internal gas fluidity and improves the overall cooling effect.

[0049] Example 2 Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the position of the air inlet 2001 can be moved, so that it can be adjusted to different positions according to different scenes, further accurately ventilating and cooling, and at the same time, the vibration is eliminated after multiple reflections in each chamber, thereby increasing the contact area and reducing the wind speed, thereby avoiding noise caused by excessive wind speed.

[0050] Specifically, a movable groove 3001 is formed through the transition bin 401 and the inner shell 1001, a rotating wheel 3002 is rotatably provided in the movable groove 3001, a belt 3003 is fitted on the outer wall of the rotating wheel 3002, a rotating column is rotatably provided on the belt 3003, and a slider 3004 is provided at the other end of the rotating column.

[0051] The air inlet 2001 is slidably disposed in the movable groove 3001 , the slider 3004 is slidably disposed on the inner wall of the air inlet 2001 , and folding curtains 3005 are respectively connected between the outer walls on both sides of the air inlet 2001 and the inner wall of the movable groove 3001 .

[0052] In this embodiment, the air inlet 2001 is a rectangular hollow frame, the moving groove 3001 is a rectangular long groove, the air inlet 2001 moves up and down along the moving groove 3001, and the slider 3004 is a rectangular block and slides along the horizontal inner wall of the air inlet 2001.

[0053] Preferably, the rotating wheels 3002 are symmetrically arranged at both ends of the movable groove 3001, and the belt 3003 rotates as a whole following the rotating wheel 3002, thereby driving the slider 3004 to move. When the air intake port 2001 moves up and down, the folding curtains 3005 on the upper and lower sides extend or contract and at the same time seal the movable groove 3001, so that the gas after heat exchange can only flow through the air intake port 2001.

[0054] Furthermore, in this embodiment, two ends of the air inlet 2001 are respectively connected to the inner shell 1001 and the outer shell 1002 to form a sealed cavity.

[0055] A flow channel plate 3006 is provided at one end of the air inlet 2001 away from the push-pull plate 2004 , an isolation chamber 3007 is vertically provided on the flow channel plate 3006 , and sound-absorbing layers 3008 are provided on both end surfaces of the air inlet 2001 and the isolation chamber 3007 .

[0056] Preferably, the sound-absorbing layer 3008 is made of foldable elastic diamond-shaped tubes, and the interior of the sound-absorbing layer 3008 is filled with sound-absorbing material to decelerate the exhaust gas and reduce wind noise. One end of the sound-absorbing layer 3008 close to the through groove 2005 is fixedly arranged on the inner wall of the through groove 2005 and the sound-absorbing layer 3008 has holes.

[0057] More preferably, the sound absorbing layer 3008 above the flow channel plate 3006 is provided with a coil groove 3009, and the sound absorbing layer 3008 below the flow channel plate 3006 is provided with an S-shaped groove 3011, and the internal spaces of the chambers on the sound absorbing layer 3008 are arranged in order from large to small.

[0058] More preferably, after the heat exchange gas flows out from the air intake 2001, it passes through the coil groove 3009, the isolation chamber 3007 and the S-shaped groove 3011 respectively, and finally flows out from the hole at one end close to the through groove 2005 to the through groove 2005, thereby increasing the contact area between the gas and the silencer material, absorbing the amplitude in the airflow, and avoiding resonance.

[0059] Among them, in other embodiments, when the air intake port 2001 and the isolation chamber 3007 slide upward synchronously along the flow channel plate 3006, the curtain 2002 is closed, so that the gas is squeezed into the sound-absorbing layer 3008 below. When sliding downward synchronously, the curtain 2002 opens, and the gas is sucked into the sound-absorbing layer 3008 above. This reciprocating process can realize the intake and heat dissipation of a single air intake port 2001 without moving the push-pull plate 2004, thereby meeting the exhaust requirements of a small flow of hot air.

[0060] In summary, when in use, the cooling gas is sprayed to the set area and then absorbs heat. After absorbing heat, it is sucked into the movable groove 3001 by the air intake port 2001 which is under negative pressure, and blows the curtain 2002 to flow out, through the coil groove 3009, the isolation chamber 3007 and the S-shaped groove 3011, and finally flows out to the through groove 2005 from the hole at one end close to the through groove 2005. Since the spaces of each chamber are distributed from large to small, most of the vibrations in the airflow are eliminated after multiple reflections. At the same time, the contact area between the gas and the sound-absorbing material can be increased, so as to absorb the vibrations in the airflow and reduce the wind speed at the same time, thereby avoiding the noise caused by excessive wind speed.

[0061] At the same time, when the heat distribution of the air compressor 100 changes in the vertical direction, the rotating wheel 3002 drives the belt 3003 to rotate, so that the slider 3004 moves with the belt 3003, and at the same time drives the air intake port 2001 to move up and down until it moves to the gas area with the highest heat, and performs air intake and heat dissipation, thereby achieving the best heat dissipation effect.

[0062] Exemplarily, in this embodiment, the control wheel 3002 is controlled to rotate continuously, and the slider 3004 is displaced laterally on the inner wall of the air intake port 2001 at the lowest and highest points, and finally moves in the opposite direction following the belt 3003, so that the air intake port 2001 can be reciprocated up and down to achieve uniform air intake of the internal area of ​​the air compressor 100, thereby enhancing the fluidity of the internal air flow and avoiding the problems of uneven internal air flow distribution and excessive differences in cooling effects of various parts caused by the fixed setting of the air intake port 2001. At the same time, as the air intake port 2001 moves, the chambers distributed from large to small on the sound-absorbing layer 3008 begin to change in proportion. The chamber of the upper sound-absorbing belt increases and the lower sound-absorbing layer 3008 decreases, thereby adjusting the noise reduction effect according to the usage scenario.

[0063] Example 3 Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the temperature parameters of the temperature sensor 4002 are monitored in real time, the ventilation and cooling position is automatically adjusted, and the inlet and outlet air flow rates are controlled according to the noise reduction and sound insulation requirements to meet the sound insulation requirements of the air compressor 100.

[0064] Specifically, a transmission shaft 4001 is disposed on the end surface of the rotating wheel 3002 , a temperature sensor 4002 is disposed in an array at one end of the belt 3003 close to the air compressor 100 , and a driven wheel 4003 is disposed on the inner wall of the inner shell 1001 .

[0065] Among them, a gear 4004 is provided at one end of the driven wheel 4003 that rotates and penetrates the cavity 301 , and a rack 4005 is also slidably provided on the cavity 301 , and the rack 4005 is fixedly connected to the adjustment frame 302 .

[0066] Furthermore, the gear 4004 is meshed with the rack 4005, and a one-way ratchet is provided between the gear 4004 and the driven wheel 4003, so that the gear 4004 rotates unidirectionally following the driven wheel 4003 and remains stationary when the driven wheel 4003 rotates in the opposite direction.

[0067] It also includes a control system, which includes an information acquisition module and an analysis module. The information acquisition module is used to obtain and record the temperature parameters of each temperature sensor 4002, and transmit the temperature parameters to the analysis module. The analysis module is used to analyze the temperature parameters of the temperature sensors 4002 arranged in various areas of the air compressor 100, build a temperature distribution model of each area outside the air compressor 100, and determine whether cooling is required based on the set temperature threshold. When ventilation and cooling are required in some areas, a control instruction is generated.

[0068] Preferably, it also includes an execution unit, which is used to receive control instructions from the analysis module and control the inlet and outlet air flow rates according to the requirements of noise reduction and sound insulation, while controlling the rotation direction and speed of the wheel 3002, so as to adjust the adjustment box 302 and the air outlet 1003 to move to the corresponding area according to the position coordinates in the control instructions.

[0069] More preferably, when the execution unit controls the rotating wheel 3002 to rotate, it will drive the driven wheel 4003 to rotate synchronously therewith, so that the gear 4004 drives the rack 4005 to move, and the adjustment frame 302 moves with the rack 4005, thereby changing the position of the adjustment frame 302 until the overlapping area of ​​the air vents 1004 is aligned with the area that needs ventilation and cooling, and then the driven wheel 4003 is controlled to rotate in the opposite direction. At this time, the position of the adjustment frame 302 remains unchanged, and cold air is continuously sprayed into the cooling area. As the driven wheel 4003 rotates counterclockwise in the opposite direction, the air outlet 1003 follows the belt 3003 to move to the cooling area, forming an in-and-out airflow cycle to cool the area to be cooled. At the same time, precise cooling reduces the total amount of airflow flow, thereby preventing the sound insulation effect from being weakened due to the in-and-out airflow.
