Description

Technical Field

[0001] The invention relates to the technical field of soundproof covers, and in particular to an integrated soundproof cover made of melamine-based sound-absorbing material. Background Art

[0002] With the rapid development of industrialization and urbanization, various types of mechanical equipment play a vital role in daily life and industrial production. However, these equipment often generate a lot of noise during operation, which not only affects the physical and mental health of operators, but also may cause noise pollution to the surrounding environment and interfere with the normal life of residents. Therefore, how to effectively reduce the noise of mechanical equipment during operation has become an urgent problem to be solved.

[0003] Among the many noise reduction measures, the integrated silent cover is popular because of its compact structure, convenient installation and significant noise reduction effect. The silent cover is wrapped around the outside of the unit to form a relatively closed space. It uses the principles of sound absorption, sound insulation and reflection to limit the noise generated by the unit within the cover, thereby achieving the purpose of noise reduction. Among them, the selection of sound-absorbing materials is crucial to the noise reduction effect of the silent cover.

[0004] As a new type of porous sound absorbing material, melamine-based sound absorbing material has been widely used in the field of noise reduction due to its excellent sound absorption performance, good heat resistance and chemical stability. Melamine-based sound absorbing materials have a large number of microporous structures inside, which can effectively absorb and consume sound energy, thereby reducing the propagation of sound. At the same time, melamine-based materials also have high heat resistance and chemical stability, and can maintain stable sound absorption performance in harsh working environments.

[0005] However, there are also some challenges when applying the integrated silent cover based on melamine-based sound-absorbing materials to the noise reduction of the unit. Among them, the most prominent problem is that after the silent cover is installed outside the unit, it is difficult to observe the operation inside the unit. This is mainly because the design of the silent cover needs to take into account the maximization of the noise reduction effect, so its structure is often relatively closed, with poor light transmittance and visibility.

[0006] Specifically, when the silent cover is completely wrapped around the outside of the unit, although it can effectively isolate the noise, it will also block the operator's direct observation of the internal status of the unit. This may make it difficult for the operator to discover and deal with the unit failure or abnormal situation in time, thus affecting the normal operation and safe production of the equipment.

[0007] Therefore, there is a need for an integrated soundproof cover made of melamine-based sound-absorbing material to overcome the above-mentioned problems. Summary of the invention

[0008] In order to solve the above problems, an embodiment of the present invention provides an integrated soundproof cover made of melamine-based sound-absorbing material, which achieves the purpose of solving the problems raised in the background technology.

[0009] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: an integrated mute cover made of melamine-based sound-absorbing material, comprising a cover body arranged outside the unit, the cover body comprising an outer shell and a melamine foam fixedly connected to the inside of the outer shell;

[0010] The cover body is provided with an observation component for observing the unit;

[0011] The observation assembly includes a through hole 1 formed on the housing, a through hole 2 formed on the melamine foam 1 and connected to the through hole 1, a universal assembly disposed inside the through hole 1, and an observation tube disposed inside the universal assembly and passing through the through hole 2;

[0012] The observation tube comprises a tube body arranged inside the universal assembly, laminated glass fixedly connected to both ends of the tube body, melamine foam 2 fixedly connected to the inside of the tube body, and melamine foam 3 fixedly connected to the outside of the tube body; the melamine foam 3 is located inside the through hole 2, and the diameter of the melamine foam 3 is greater than the diameter of the through hole 2;

[0013] When the cylinder is rotated to observe the unit inside the cover, the melamine foam three is in a compressed state to keep the through hole two in a sealed state.

[0014] As a further improvement of the above technical solution:

[0015] The universal joint assembly comprises a connecting ring 1 rotatably arranged inside a through hole 1, and a connecting ring 2 rotatably arranged inside the connecting ring 1; the rotation direction of the connecting ring 1 is perpendicular to the rotation direction of the connecting ring 2.

[0016] The observation assembly also includes a compensation assembly arranged inside the cover body for observing the unit; the compensation assembly is used to cover the blind area when the observation tube directly observes.

[0017] The compensation component includes a through groove opened on the shell, a gap opened on the melamine foam and connected to the through hole, a connecting piece passed through the gap, an adjusting piece passed through the gap, and an observation mirror hinged at the end of the connecting piece and the end of the adjusting piece; the connecting piece and the adjusting piece are both hard thin sheets.

[0018] The outer part of the shell is fixedly connected with a guide rail, and the connecting piece is fixedly connected with a sliding block which is slidably arranged inside the guide rail.

[0019] A cover is arranged outside the guide rail.

[0020] One side of the melamine foam 1, the melamine foam 2 and the melamine foam 3 is provided with a sound absorbing groove.

[0021] The cover body is formed by splicing a symmetrical left half and a right half that are hinged to each other, and the melamine foam is arranged to protrude from the edge of the shell.

[0022] The bottom of the left half and the bottom of the right half are both provided with wheel sets;

[0023] The wheel set comprises a fixing block fixedly connected to the outside of the housing, a screw rod threadedly connected to the inside of the fixing block, and a universal wheel arranged at the bottom end of the screw rod.

[0024] The cover body is provided with a heat dissipation component for dissipating heat;

[0025] The heat dissipation assembly comprises a heat dissipation hole opened on the cover body, a heat dissipation fan arranged at the heat dissipation hole, and a noise reduction unit arranged outside the cover body and connected to the heat dissipation hole.

[0026] The beneficial effects of the embodiments of the present invention are:

[0027] The cover body is provided with an observation assembly for observing the unit; the unit inside the cover body can be observed through the observation assembly, so that the staff can timely grasp the working status of the unit; when observing the unit inside the cover body through the observation assembly, the staff can observe the operation of the unit through the observation tube, and at the same time, the direction of the observation tube can be adjusted through the universal assembly, so as to observe different positions of the unit;

[0028] Under normal circumstances, an observation window is provided on the cover body to facilitate observation of the unit inside the cover body, but the observation window is usually made of glass, and its noise reduction effect is limited. Even if the glass is replaced with vacuum glass with a certain noise reduction effect, it still cannot achieve a good noise reduction effect. At the same time, in order to have a sufficient observation range, the size of the observation window is usually large, which further aggravates the intensity of the noise. Therefore, the present application adopts an observation tube to observe the unit inside the cover body. First, the melamine foam arranged inside the tube body and the laminated glass arranged at both ends of the tube body can effectively reduce the noise passing through the inside of the tube body. At the same time, the tube body can be moved through the universal assembly, which reduces the diameter of the tube body while ensuring a sufficient observation range, further reduces the transmission intensity of the noise, and avoids the transmission of the unit noise.

[0029] The observation assembly also includes a compensation assembly arranged inside the cover body for observing the unit; the compensation assembly is used to cover the blind area when the observation tube is directly observed; the compensation assembly is used in conjunction with the observation tube, and when the observation tube is used to observe the unit, the back of the unit cannot be observed through the observation tube, so the compensation assembly is used to cover the blind area when the observation tube is observed, so that the back of the unit can be observed through the observation tube;

[0030] The connecting piece and the adjusting piece are both hard thin pieces, so that the thickness of the connecting piece and the adjusting piece is relatively small. When the connecting piece and the adjusting piece are inserted into the inside of the gap, based on the elastic properties of the melamine foam, the melamine foam can clamp the connecting piece and the adjusting piece inserted into the inside of the gap, so that no gap is generated at the gap, thereby preventing noise from being transmitted.

[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0052] See also Figures 1 to 12 The embodiment of the present invention discloses an integrated mute cover made of melamine-based sound-absorbing material, comprising a cover body 1 arranged outside the unit, the cover body 1 comprising an outer shell 11 and a melamine foam 12 fixedly connected to the inside of the outer shell 11; the melamine foam is a flexible open foam made of melamine as a raw material, which has excellent sound absorption; the melamine foam 12 is used to reduce the working noise of the unit inside the cover body 1;

[0053] The cover body 1 is provided with an observation component 2 for observing the unit; the unit inside the cover body 1 is observed through the observation component 2, so that the staff can grasp the working status of the unit in time;

[0054] The observation assembly 2 includes a through hole 1 21 formed on the housing 11, a through hole 22 formed on the melamine foam 12 and connected to the through hole 1 21, a universal assembly 23 disposed inside the through hole 1 21, and an observation tube 24 disposed inside the universal assembly 23 and passing through the through hole 22;

[0055] When observing the unit inside the housing 1 through the observation assembly 2, the staff can observe the operation of the unit through the observation tube 24, and at the same time, the direction of the observation tube 24 can be adjusted through the universal assembly 23 to observe different positions of the unit;

[0056] In actual use, the observation tube 24 is mainly directed toward the working status indicator light of the unit. This is because the cover body 1 forms a closed space after the unit is covered therein, so that the inside of the cover body 1 is relatively dark, and it is difficult to observe through the observation tube 24. However, the working status indicator light is a luminous body, which is convenient for observing the working status indicator light through the observation tube 24. At the same time, in order to solve the problem that the inside of the cover body 1 is dark and difficult to observe through the observation tube 24, a lighting lamp can be installed inside the cover body 1, so that the internal space of the cover body 1 is illuminated by the lighting lamp, which is convenient for observation.

[0057] The observation tube 24 includes a tube body 241 arranged inside the universal assembly 23, a laminated glass 242 fixedly connected to both ends of the tube body 241, a melamine foam 243 fixedly connected inside the tube body 241, and a melamine foam 3 244 fixedly connected to the outside of the tube body 241; the melamine foam 3 244 is located inside the through hole 22, and the diameter of the melamine foam 3 244 is greater than the diameter of the through hole 22; the melamine foam has good elasticity, and when the diameter of the melamine foam 3 244 is greater than the diameter of the through hole 22, the melamine foam 3 244 and the melamine foam 1 12 are both in a compressed state, so that when the tube body 241 moves, the compression and deformation recovery of the melamine foam 3 244 and the melamine foam 1 12 can ensure the closed state of the through hole 22, thereby preventing noise from penetrating from the through hole 22;

[0058] When the cylinder 241 is rotated to observe the unit inside the housing 1, the melamine foam 3 244 is in a compressed state to keep the through hole 22 in a sealed state;

[0059] In actual use, the staff observes the operation of the unit inside the cover body 1 through the cylinder 241, and fills the through hole 22 with the melamine foam 244 on the cylinder 241, so as to prevent the noise of the unit from being transmitted through the through hole 22 when the unit is running; at the same time, the noise of the unit operation is also easy to be transmitted from the inside of the cylinder 241, and the melamine foam 243 inside the cylinder 241 is used to reduce the noise passing through the inside of the cylinder 241; the inside of the cylinder 241 adopts the laminated glass 242, and the laminated glass 242 has a certain noise reduction effect, so as to further reduce the noise;

[0060] Under normal circumstances, an observation window is provided on the cover body 1 to facilitate observation of the unit inside the cover body 1. However, the observation window is usually made of glass, and its noise reduction effect is limited. Even if the glass is replaced with vacuum glass with a certain noise reduction effect, a good noise reduction effect cannot be achieved. At the same time, in order to have a sufficient observation range, the size of the observation window is usually large, which further aggravates the intensity of the noise. Therefore, the present application adopts an observation tube 24 to observe the unit inside the cover body 1. First, the melamine foam 243 arranged inside the tube 241 and the laminated glass 242 arranged at both ends of the tube 241 can effectively reduce the noise passing through the inside of the tube 241. At the same time, the tube 241 can be moved through the universal assembly 23. The diameter of the tube 241 is reduced while ensuring a sufficient observation range, thereby further reducing the transmission intensity of the noise and avoiding the transmission of the unit noise.

[0061] As a further illustration of this application:

[0062] The universal joint assembly 23 includes a connecting ring 1 231 rotatably arranged inside the through hole 1 21, and a connecting ring 232 rotatably arranged inside the connecting ring 1 231; the rotation direction of the connecting ring 1 231 and the rotation direction of the connecting ring 2 232 are perpendicular; the cylinder 241 is arranged inside the connecting ring 2 232, and the cylinder 241 can be rotated at different angles through the connecting ring 1 231 and the connecting ring 2 232.

[0063] As a further illustration of this application:

[0064] The observation component 2 also includes a compensation component 25 arranged inside the cover body 1 for observing the unit; the compensation component 25 is used to cover the blind area when the observation tube 24 is directly observed; the compensation component 25 is used in conjunction with the observation tube 24. When the observation tube 24 is used to observe the unit, the back of the unit cannot be observed through the observation tube 24. Therefore, the compensation component 25 is used to cover the blind area when the observation tube 24 is observed, and the back of the unit can be observed through the observation tube 24.

[0065] As a further illustration of this application:

[0066] The compensation component 25 includes a through groove 251 provided on the housing 11, a slit 252 provided on the melamine foam 12 and connected to the through hole 21, a connecting piece 253 inserted into the slit 252, an adjusting piece 254 inserted into the slit 252, and an observation mirror 255 hinged at the ends of the connecting piece 253 and the ends of the adjusting piece 254; the connecting piece 253 and the adjusting piece 254 are both hard sheets, so that the thickness of the connecting piece 253 and the adjusting piece 254 is small. When the connecting piece 253 and the adjusting piece 254 are inserted into the slit 252, based on the elastic properties of the melamine foam 12, the melamine foam 12 can clamp the connecting piece 253 and the adjusting piece 254 inserted into the slit 252, so that no gap is generated at the slit 252, thereby preventing noise from being transmitted;

[0067] The sound absorption of the melamine foam 12 is due to the presence of many holes inside the melamine foam 12, which results in a large friction force at the gap 252. When the connecting piece 253 and the adjusting piece 254 are inserted into the gap 252, the connecting piece 253 and the adjusting piece 254 can be limited to prevent the connecting piece 253 and the adjusting piece 254 from moving on their own.

[0068] In actual use, the back of the unit is reflected by the observation mirror 255, so that the back of the unit can be observed by the cooperation of the observation tube 24 and the observation mirror 255. Specifically, after the observation mirror 255 is adjusted to a suitable angle, the observation mirror 255 is observed through the observation tube 24, and the back of the unit can be observed through the reflection of the observation mirror 255;

[0069] When adjusting the angle of the observation mirror 255 , the angle of the observation mirror 255 can be adjusted by adjusting the positions of the connecting piece 253 and the adjusting piece 254 ; meanwhile, the length of the gap 252 determines the moving range of the observation mirror 255 .

[0070] As a further illustration of this application:

[0071] The outside of the shell 11 is fixedly connected to the guide rail 3, and the connecting piece 253 is fixedly connected to the slider 4 which is slidably arranged inside the guide rail 3. In actual use, the movement of the connecting piece 253 is restricted by the slider 4, so that the connecting piece 253 can only move along the guide rail 3, that is, the position of the observation mirror 255 is adjusted by the connecting piece 253; the adjusting piece 254 can move inside the gap 252, and can be pulled and tilted inside the gap 252, so that the angle of the observation mirror 255 can be adjusted by the adjusting piece 254; that is, in actual use, the position of the observation mirror 255 is adjusted by the connecting piece 253, and the angle of the observation mirror 255 is adjusted by the adjusting piece 254.

[0072] As a further illustration of this application:

[0073] A cover 5 is provided on the outside of the guide rail 3. After the position of the observation mirror 255 is adjusted by the connecting piece 253 and the adjusting piece 254, the cover 5 is covered on the outside of the guide rail 3 to protect the connecting piece 253 and the adjusting piece 254 to avoid accidental touching of the connecting piece 253 and the adjusting piece 254.

[0074] As a further illustration of this application:

[0075] A sound absorbing groove 6 is provided on one side of the melamine foam 12, the melamine foam 243 and the melamine foam 3 244; the sound absorbing groove 6 is used to reflect and absorb sound waves multiple times, thereby improving the noise reduction effect;

[0076] At the same time, in order to improve the noise reduction effect, the cylinder 241 can be set to be a trumpet shape, that is, the melamine foam 243 is inclined as a whole, which is convenient for the melamine foam 243 to reflect and absorb noise.

[0077] As a further illustration of this application:

[0078] The cover body 1 is formed by splicing together a symmetrical left half and a right half that are hinged to each other, so that the cover body 1 can be easily covered on the outside of the unit; the melamine foams 12 are all arranged protruding from the edge of the outer shell 11. When the cover body 1 is spliced ​​together, the melamine foams 12 protruding from the edge of the outer shell 11 can ensure that they fit together; when the cover body 1 is located on the ground, the melamine foams 12 protruding from the bottom of the outer shell 11 can ensure that they fit on the ground, thereby ensuring the sound insulation effect.

[0079] As a further illustration of this application:

[0080] The bottom of the left half and the bottom of the right half are both provided with a wheel set 7;

[0081] The wheel set 7 includes a fixed block 71 fixedly connected to the outside of the housing 11, a screw rod 72 threadedly connected to the inside of the fixed block 71, and a universal wheel 73 arranged at the bottom end of the screw rod 72; when it is necessary to open the cover body 1, the screw rod 72 is rotated so that the screw rod 72 extends from the inside of the fixed block 71, and then the universal wheel 73 is supported on the ground to lift the cover body 1, and then the left half and the right half can be pushed to move, so that the cover body 1 can be opened; when it is not necessary to move the cover body 1, the screw rod 72 is rotated so that the universal wheel 73 moves upward, so that the cover body 1 is supported on the ground;

[0082] When the cover body 1 is moved, the universal wheel 73 is supported on the ground, that is, the cover body 1 does not contact the ground, so that the melamine foam 12 protruding from the bottom of the shell 11 does not contact the ground, thereby facilitating the movement of the cover body 1.

[0083] As a further illustration of this application:

[0084] The cover body 1 is provided with a heat dissipation component 8 for dissipating heat;

[0085] The heat dissipation component 8 includes a heat dissipation hole 81 opened on the cover body 1, a heat dissipation fan 82 arranged at the heat dissipation hole 81, and a noise reduction unit 83 arranged outside the cover body 1 and connected to the heat dissipation hole 81; two heat dissipation components 8 are provided, one heat dissipation component 8 is for air intake, and the other heat dissipation component 8 is for air outlet, and the gas circulation inside the cover body 1 is realized through the two heat dissipation components 8, thereby realizing the heat dissipation inside the cover body 1;

[0086] In actual use, the cooling fan 82 in one of the cooling components 8 ventilates the interior of the cover body 1, and the cooling fan 82 in the other cooling component 8 draws out the air inside the cover body 1, thereby achieving air circulation inside the cover body 1;

[0087] The noise of the air entering and exiting the cover body 1 is reduced by the noise reduction unit 83. The noise reduction unit 83 can adopt a noise reduction unit proposed in a cold aluminum ash processing equipment with noise reduction and dust removal function and its noise reduction unit disclosed in CN114289312B. This application will no longer specifically describe the specific structure and specific working principle of the noise reduction unit 83.

[0088] As a further illustration of this application:

[0089] A through hole is provided on the top of the cover body 1, and the pipes and wiring harnesses in the unit can pass through the through hole and out of the cover body 1.

[0090] The working steps / principles of this application are:

[0091] The cover body 1 is arranged outside the unit, and the noise generated by the unit during operation is mainly reflected and absorbed by the melamine foam 12 provided with the sound-absorbing groove 6 to achieve noise reduction;

[0092] When it is necessary to observe the operating status of the unit inside the housing 1, the unit is observed through the cylinder 241; the back of the unit is observed through the reflection of the observation mirror 255;

[0093] When adjusting the observation mirror 255, the position of the observation mirror 255 is adjusted by the connecting piece 253, and the angle of the observation mirror 255 is adjusted by the adjusting piece 254;

[0094] When the cover body 1 is moved, the screw rod 72 is rotated to make the universal wheel 73 supported on the ground to lift the cover body 1, so that the cover body 1 can be pushed to move.
