[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 8 As shown, the present invention provides a silent powered skid device, comprising: a base 1, a sound-absorbing wall 2 surrounding the base 1, and a sound-absorbing ceiling 3, which are detachably connected from bottom to top to form a closed powered skid body; a working device is provided inside the powered skid body, and an air outlet silencer 11 is provided inside the powered skid body corresponding to the main noise component that generates noise from the working device; an exhaust fan 12 is provided on the inner wall of the sound-absorbing wall 2 corresponding to the main noise component; an air outlet is provided on the sound-absorbing ceiling 3 corresponding to the air outlet silencer 11, and a dustproof plate 4 is rotatably connected to the air outlet; an air inlet silencer 5 is embedded in the sound-absorbing wall 2 at the end of the powered skid body away from the air outlet silencer 11.

[0021] In this technical solution, the sound-absorbing wall 2 and the sound-absorbing ceiling 3 constitute a sound-absorbing cover structure, achieving overall noise reduction by interrupting the propagation path of noise generated by the working equipment inside the power skid body and absorbing noise. The base 1, the sound-absorbing wall 2, and the sound-absorbing ceiling 3 are connected sequentially by fasteners. As an example, the working equipment in this embodiment is a continuous tubing device, and the silent power skid device can also be applied to other special equipment. For the continuous tubing device, its main noise-generating device is the power system 6. Therefore, the power system 6 is set at one end inside the power skid body, and the exhaust silencer 11 is set next to it. Then, the intake silencer 5 is set on the sound-absorbing wall 2 at the other end. By setting an exhaust fan 12 near the power system 6, an air circulation path is formed inside the power skid body. That is, external air enters the power skid body through the intake silencer 5. Under the action of the exhaust fan 12, the heat generated during the operation of the working equipment is carried away and discharged through the exhaust silencer 11 and the air outlet. Therefore, the silent power skid device, while achieving air convection within the power skid body, also ensures that noise is not transmitted outside the skid or is attenuated to a low noise frequency. Through noise spectrum analysis and sound insulation calculation, the noise reduction effect of the silent power skid device is improved by more than 40% compared to conventional power skid devices, ensuring that the noise level of the engine 10 at a distance of 1 meter from the power skid does not exceed 85 decibels under normal operation. Preferably, the sound-absorbing wall 2 has air intake sound-absorbing bodies 5 on both opposite sides, the number of exhaust fans 12 is flexibly set according to heat dissipation requirements, and the inner wall of the sound-absorbing wall 2 is equipped with a temperature control switch for the exhaust fans 12, which integrates a temperature sensor and is set to turn on the exhaust fan 12 when the temperature inside the power skid body is detected to be higher than 60°C. In another technical solution, such as Figures 4 to 6 The air intake silencing body 5 includes two sets of acoustic black hole structures 51 and a labyrinthine silencing structure 52 disposed between them. The acoustic black hole structure 51 includes a first shell 511 and noise reduction unit bodies 512 evenly distributed on the shell 511. The noise reduction unit body 512 is a cylinder with one open end. Multiple first sound absorption holes are provided on the inner wall and bottom plate of the noise reduction unit body 512. Multiple sound wave baffles 513 are spaced apart along the axial direction inside the noise reduction unit body 512. Each sound wave baffle 513 has a second sound absorption hole. Each second sound absorption hole is coaxially arranged with the noise reduction unit body 512, and the hole diameter decreases sequentially from the open end to the bottom plate. The noise reduction unit bodies 512 on the two acoustic black hole structures 51 are symmetrically arranged, and the open ends of both face away from the labyrinthine silencing structure 52.

[0022] Furthermore, such as Figure 4As shown, the labyrinthine noise reduction structure 52 includes a second housing, and multiple labyrinthine channels are arranged from top to bottom inside the second housing; both ends of each labyrinthine channel extend to the outside of the second housing and respectively abut against the bottom plate of the noise reduction unit 513 of the two sets of acoustic black hole structures 52.

[0023] The labyrinthine silencing structure 52 in the air intake silencing body 5 is fixed to the middle of the two sets of acoustic black hole structures 51 by welding. The first shell 511 of the acoustic black hole structure 51 is a hollow cuboid structure, and then the mounting holes of each noise reduction unit 512 are stamped out. The remaining space inside the first shell 511 is filled with sound-absorbing cotton strips. The structure of the noise reduction unit 512 is as follows: Figure 6 As shown, external air circulates into the interior of the power skid body through the first sound-absorbing holes, the second sound-absorbing holes, and the labyrinthine channels. The second shell of the labyrinthine noise-absorbing structure 52 has the same size and structure as the first shell 511, and its interior forms multiple continuous wave-shaped labyrinthine channels through partitions. When the working equipment is running, noise waves enter the acoustic black hole structure 51 near the interior of the power skid body. First, the sound waves reach the first sound wave baffle 513. Part of the sound waves continue to be transmitted through the second sound-absorbing holes on the sound wave baffle 513, while another part of the sound waves is blocked and refracted by the first sound wave baffle 513 and then enters the first shell 511 through the first sound-absorbing holes on the noise reduction unit 512. Multiple refractions occur gradually inside, and the noise energy is converted into heat energy, causing the sound wave intensity to gradually weaken. It is further absorbed by the sound-absorbing strips, further reducing the noise energy until all the noise energy is converted into heat energy. In this manner, the second and last sound wave baffles 513 separate and eliminate sound waves respectively, thereby weakening some of the noise sound waves. The remaining noise sound waves finally enter the corresponding labyrinthine channel through the first sound-absorbing hole on the bottom plate of the noise reduction unit 513. In the labyrinthine channel, multiple refractions and absorptions are performed to weaken the noise waves. The weakened sound waves are discharged through the acoustic black hole structure 51 on the outside. At this time, the output noise sound waves have a significantly reduced intensity compared to the original noise sound waves.

[0024] The acoustic black hole structures 51 on both sides of the air intake silencer body 5 are symmetrically arranged, so that there is no need to distinguish between the front and back of the air intake silencer body 5 during installation, and the silent power device can achieve bidirectional sound wave noise reduction from the inside to the outside and from the outside to the inside.

[0025] In another technical solution, the air outlet silencing body 11 includes a plurality of vibration damping and noise reduction plates 111 fixedly mounted on a bracket, and a power rod assembly 112 is provided between two adjacent vibration damping and noise reduction plates 111; a drive assembly 113 is fixedly mounted on the bracket, and the drive assembly 113 is used to drive each of the power rod assemblies 112 to rotate.

[0026] Furthermore, such as Figure 8 As shown, the vibration damping and noise reduction plate 111 includes a third shell 1114 and a labyrinthine core 1111, a damping rubber layer 1112, and a rigid sound-absorbing cotton layer 1113 arranged sequentially from the inside to the outside within the third shell 1114. The third shell 1114 includes multiple layers of wall panels, each layer of which is uniformly provided with multiple third sound-absorbing holes, and the third sound-absorbing holes on adjacent layers of wall panels are staggered. Considering that the exhaust silencer 11 is located close to the power system 6, the vibration of the power system 6 during operation must also be considered while reducing noise. Therefore, after the exhaust silencer 11 is installed, multiple vibration damping and noise reduction plates 111 are installed, wherein the third shell 1114 is a hollow structure, and the noise wave blocking effect is formed through the third sound-absorbing holes on it. Some of the sound waves that enter the interior of the third shell 1114 are reflected and collided by the multi-fiber structure of the rigid sound-absorbing cotton layer 1113, and part of them are converted into heat energy, which further weakens the sound wave intensity. The rigid sound-absorbing cotton layer 1113 is nested inside the damping rubber layer, mainly used for vibration reduction, mitigating the resonance hazards caused by the vibration of the dynamic system, and improving the service life and effectiveness of the vibration damping and noise reduction plate 111. The labyrinth-shaped core 1111 includes multiple stacked E-shaped sound-absorbing panels. Sound waves are refracted multiple times within the labyrinth-shaped body 1111 and are ultimately completely absorbed. Since the vibration damping and noise reduction plate 111 only has a sound wave incident end and no sound wave emitting end, the sound waves entering its interior will be completely absorbed by its structure.

[0027] Furthermore, such as Figure 7As shown, the power rod assembly 112 includes a vertically arranged power rod 1121, the bottom of which is rotatably connected to the bracket. Multiple noise reduction components are fixedly mounted on the power rod 1121. Each noise reduction component includes a fan 1122 and a barrier 1123 arranged sequentially from bottom to top. The barrier 1123 is horn-shaped and fitted onto the power rod 1121, with its diameter gradually increasing from bottom to top. The power rod assembly 112 serves as the execution structure for the air outlet silencer body 11. The power rod 1121 rotates under the action of the drive assembly 113, thereby driving the fan 1122 and the barrier 1123 to rotate. The fan 1122 causes the noise sound waves to flow upward rapidly. When the noise sound waves are incident on the barrier 1123, air movement is formed at the top of the barrier 1123. Due to the viscous resistance of the air and the frictional resistance at the top, some of the sound energy is converted into heat energy, achieving partial noise attenuation. The vibration damping and noise reduction plates 111 on both sides further reduce the remaining noise. Preferably, the drive assembly 113 can be equipped with a drive motor for each power rod 1121, or a gear set or other transmission mechanism can be used to enable one drive motor to drive multiple power rods 1121 to rotate. In another technical solution, a partition wall 9 is provided inside the power skid body, dividing the interior of the power skid body into a control compartment and an equipment compartment. The sound-absorbing wall 2, the partition wall 9, and the sound-absorbing ceiling 3 have the same structure, all including a fourth shell and rigid sound-absorbing cotton filled in the fourth shell. Multiple layers of sound-absorbing panels are provided on the side of the fourth shell facing the interior of the power skid body. Each layer of the sound-absorbing panel has multiple fourth sound-absorbing holes, and the fourth sound-absorbing holes on adjacent layers are staggered. The sound-absorbing panels are metal plates, and the number of fourth sound-absorbing holes per square meter of the sound-absorbing panel is not less than 10,000. When sound waves enter the sound-absorbing panel, they are continuously weakened and interrupted during propagation through the staggered fourth sound-absorbing holes. Combined with the rigid sound-absorbing cotton, this ensures the noise reduction and sound insulation effect of the power skid body. The equipment compartment is mainly used to install the power system 6 and generator 8, which generate noise and heat, as well as the hydraulic oil tank 7 required for the operation of the power system 6 and generator 8. Therefore, the air inlet silencer 5 and the air outlet silencer 11 are both located in the equipment compartment to ensure the noise reduction effect of the equipment compartment. The control compartment is equipped with a power hose roller, an accumulator, and a control box, etc.; the partition wall 9 has hydraulic pipeline holes 25 and electrical pipeline holes 24, which enable the control of the equipment in the equipment compartment from within the control compartment.

[0028] In another technical solution, the sound-absorbing wall 2 is provided with one or more sound-absorbing doors 10. The structure of the sound-absorbing door 10 is the same as that of the sound-absorbing wall 2, and sound-absorbing rubber is fixed on the sound-absorbing wall 2 at the connection point with the sound-absorbing door 10. The sound-absorbing door is mainly used for maintenance or equipment access. The sound-absorbing rubber ensures that after the sound-absorbing door is closed, the internal noise will not leak out through the connection point between the sound-absorbing door 10 and the sound-absorbing wall 2.

[0029] In another technical solution, the dustproof panel 4 is a fiberglass grating, one side of which is connected to the sound-absorbing ceiling 2 via a hinge. A ladder is provided on the outside of the sound-absorbing wall 2. When the silent powered sled is not in operation, the operator climbs the ladder to the top and flips the dustproof panel 4 over to cover the air outlet, preventing debris such as branches and sand from entering the silent powered sled. When the silent powered sled is in operation, the dustproof panel 4 is flipped open to ensure the ventilation of the air outlet silencer 11.

[0030] In another technical solution, a muffler 13 is provided on the main noise-generating equipment. Taking a coiled tubing system as an example, mufflers 13 are provided at both the engine exhaust pipe and the generator exhaust pipe in the power system 6 to reduce the gas noise in the engine exhaust pipe and the generator exhaust pipe.

[0031] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
