Description

Technical Field

[0001] This utility model relates to the field of sound insulation structure technology, and in particular to a sound insulation structure for noise control in power plants. Background Technology

[0002] As a key hub in the energy sector, power plants are factories that convert natural energy into electrical energy. During the operation of power plants, the continuous operation of various equipment generates high-intensity noise. This noise not only disturbs the surrounding ecological environment and affects the normal living habits of plants and animals, but also has a serious negative impact on the quality of life of nearby residents. Long-term exposure to noise can cause hearing damage, sleep disorders, and cardiovascular diseases in residents.

[0003] A search revealed Chinese patent publication number CN211525853U, which discloses a noise control structure for a computer room. The structure includes a base with four symmetrically fixed support feet at its bottom. A soundproof cover is attached to the end of the base away from the support feet. A main unit chassis is fixedly installed at the top of the base, inside the soundproof cover. Several clips are symmetrically fixed to the two outer side walls of the main unit chassis, each clip holding a water pipe. A water outlet is fixedly installed at the end of the soundproof cover away from the base. An inlet is fixedly installed on one side of the outlet, and one end of the inlet is fixedly connected to the water pipe. The end of the water pipe away from the inlet is fixedly connected to the outlet. This utility model is a noise control structure for computer rooms. The noise control structure is equipped with a soundproof cover, which can cover the host chassis in a closed space, effectively improving its sound insulation effect. At the same time, water cooling is used to cool and dissipate heat from the host chassis, effectively improving its heat dissipation performance. However, in actual use, it needs to be installed by several clips in sequence, which is cumbersome during installation and disassembly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a noise control and sound insulation structure for power plants, aiming to improve the problem of the existing technology requiring installation through a series of corresponding clips, which makes the installation and disassembly process cumbersome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a noise control and sound insulation structure for power plants, comprising a base, wherein a fixing plate 1 is fixedly connected to both the left and right sides of the base, and a fixing plate 2 is fixedly connected to the rear side of the base; a sliding groove 1 is provided on the top of each of the two fixing plates 1, and a sliding groove 2 is provided on the top of the fixing plate 2; a metal plate 1 is slidably connected inside each of the two sliding grooves 1, and a metal plate 2 is slidably connected inside the sliding groove 2; a fixing groove is provided at both ends of the front side of the metal plate 2; fixing bolts are rotatably connected to the upper and lower ends of the left and right sides of the metal plate 2; the rear sides of the two metal plates 1 are slidably connected to the interior of the corresponding fixing grooves; two fixing holes are provided at the rear ends of the two metal plates 1 on opposite sides; glass wool boards are fixedly connected to the adjacent sides of the two metal plates 1 and the front side of the metal plate 2; an installation groove is provided on the top of the base; and a shock-absorbing mechanism is provided on the top of the base.

[0006] Through the above technical solution: when using the noise control and sound insulation structure for power plants, during installation, the sliding groove 1 on the top of fixed plate 1 and the sliding groove 2 on the top of fixed plate 2 are used to flexibly install metal plate 1 and metal plate 2 respectively. Metal plate 1 and metal plate 2 can initially block noise. By using fixing bolts to pass through the fixing grooves and turn into the corresponding fixing holes, metal plate 1 and metal plate 2 can be firmly connected to ensure the stability of the sound insulation structure. Glass wool boards are fixedly connected to the adjacent side of the two metal plates 1 and the front side of the metal plate 2. Glass wool boards have excellent sound absorption characteristics. During the propagation process, noise will be absorbed by the multi-layer composite structure composed of glass wool boards, metal plate 1 and metal plate 2, thereby achieving efficient sound insulation and noise reduction.

[0007] As a further description of the above technical solution:

[0008] The shock absorption mechanism includes multiple telescopic rods. One end of each telescopic rod is fixedly connected to one side of a corresponding glass wool board, and the other end of each telescopic rod is fixedly connected to a corresponding U-shaped plate. Both ends of two adjacent sides of the two U-shaped plates are provided with circular grooves. Springs are fixedly connected inside the multiple circular grooves, and the other end of each of the multiple springs is fixedly connected to a corresponding shock absorption plate.

[0009] Through the above technical solution: when the power plant equipment installed in the mounting slot vibrates during operation, the telescopic rod pushes the U-shaped plate towards the center according to the size of the equipment, causing the two damping plates to clamp the equipment. At this time, the vibration is transmitted to the damping plates, and the damping plates compress the spring, causing it to contract into the circular groove, which causes the spring to deform. The spring has good elastic potential energy and can absorb and buffer the energy of the vibration.

[0010] As a further description of the above technical solution:

[0011] A switch is fixedly connected to the front side of the base, and the switch is electrically connected to the telescopic rod.

[0012] The above technical solution is used to control the extension and retraction of the telescopic rod, and to adjust the position of the sound insulation structure or the shock absorption effect when needed.

[0013] As a further description of the above technical solution:

[0014] The base has movable slots on the front and back sides of its top, and movable blocks are fixedly connected to the front and back sides of the bottom of the two U-shaped plates.

[0015] The above technical solution provides a movable space for the shock absorption mechanism, allowing for flexible adjustment of its position in different usage scenarios.

[0016] As a further description of the above technical solution:

[0017] The front side of each of the two metal plates is provided with a protective plate, and the rear side of each of the two protective plates is provided with a protective groove. The two protective grooves are slidably connected to the front outer wall of the corresponding metal plate.

[0018] The above technical solution can protect the metal plate, prevent it from being hit or scratched by external forces, and extend its service life.

[0019] As a further description of the above technical solution:

[0020] Limiting grooves are provided on the front and rear sides of the interior of the two U-shaped plates, and limiting blocks are fixedly connected to the front and rear sides of the two damping plates. The multiple limiting blocks are slidably connected to the interior of the corresponding limiting grooves.

[0021] The above technical solution avoids excessive displacement of the damping plate during the damping process, ensuring stable operation of the damping mechanism in a vibration environment and maintaining a good damping effect.

[0022] As a further description of the above technical solution:

[0023] The outer walls of the plurality of fixing bolts are slidably connected with washers, and one side of each of the plurality of washers is respectively attached to one side of the corresponding metal plate.

[0024] The above technical solution can increase the contact area between the fixing bolt and the second metal plate, and disperse the pressure when tightening the fixing bolt, preventing the surface of the second metal plate from being damaged due to excessive local pressure.

[0025] As a further description of the above technical solution:

[0026] One end of each of the fixing bolts passes through the fixing groove and is rotatably connected to the inside of the corresponding fixing hole, and the size of the fixing bolt and the fixing hole are matched.

[0027] The above technical solution firmly connects metal plate one and metal plate two, ensuring the stability of the sound insulation structure frame and enabling the entire sound insulation structure to withstand certain external forces.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, metal plate one and metal plate two are flexibly installed through sliding groove one and sliding groove two, and fixed bolts are used to pass through the fixed groove and rotate into the corresponding fixed hole for secure connection. The glass wool board and the metal plate form a composite structure for sound insulation, which realizes convenient installation, stable structure, and efficient sound insulation and noise reduction, effectively reducing noise pollution from power plants.

[0030] 2. In this utility model, when the power plant equipment vibrates during operation, the telescopic rod pushes the U-shaped plate to move according to the size of the equipment, which drives the damping plate to clamp the equipment. The vibration is transmitted to the damping plate, causing it to compress the spring. The spring contracts and deforms in the circular groove, absorbing and buffering the vibration energy, thus achieving effective vibration reduction of the equipment, ensuring stable operation of the equipment, and reducing noise and component wear caused by vibration.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a noise control and sound insulation structure for power plants, including a base 1. Fixing plates 3 are fixedly connected to both the left and right sides of the base 1, forming a side frame support structure. A fixing plate 4 is fixedly connected to the rear side of the base 1, forming a rear frame support structure and completing the overall frame. Sliding grooves 5 are provided on the top of both fixing plates 3, allowing metal plates 7 to slide flexibly. Sliding grooves 6 are provided on the top of the fixing plate 4, allowing metal plates 8 to slide flexibly. Metal plates 7 are slidably connected inside both sliding grooves 5, providing initial noise isolation and structural support. Metal plates 8 are slidably connected inside sliding grooves 26, also providing initial noise isolation and structural support. Fixing grooves 9 are provided at both ends of the front side of the metal plate 8, facilitating the installation of metal plates 7. The upper and lower ends of the left and right sides of the second metal plate 8 are rotatably connected with fixing bolts 10. The fixing bolts 10 are used to securely connect the first metal plate 7 and the second metal plate 8. The rear sides of the two first metal plates 7 are slidably connected to the interior of the corresponding fixing grooves 9. The rear ends of the two metal plates 7 on the opposite sides are provided with two fixing holes 11. The fixing holes 11 cooperate with the fixing bolts 10 to achieve a secure connection. The adjacent sides of the two first metal plates 7 and the front sides of the second metal plate 8 are fixedly connected with glass wool boards 12. The glass wool boards 12 have excellent sound absorption characteristics and can efficiently absorb noise. The top of the base 1 is provided with a mounting groove 13. The mounting groove 13 facilitates the fixing with other equipment. The top of the base 1 is provided with a shock absorption mechanism 2. The shock absorption mechanism 2 is used to absorb and buffer external vibrations to ensure the stability of the sound insulation structure. The front side of the base 1 is fixedly connected with a switch 14. The switch 14 is used to control the extension and retraction of the telescopic rod 201. The switch 14 is electrically connected to the telescopic rod 201 to realize remote control of the telescopic rod 201.

[0040] Specifically, when using the noise control and sound insulation structure for power plants, during installation, the sliding groove 5 on the top of the fixed plate 1 and the sliding groove 6 on the top of the fixed plate 2 are used to flexibly install the metal plate 1 7 and the metal plate 2 8 respectively. The metal plate 1 7 and the metal plate 2 8 can initially block noise. By using the fixing bolts 10 to pass through the fixing grooves 9 and rotate into the corresponding fixing holes 11, the metal plate 1 7 and the metal plate 2 8 can be firmly connected to ensure the stability of the sound insulation structure. Glass wool boards 12 are fixedly connected to the adjacent side of the two metal plates 1 7 and the front side of the metal plate 2 8. The glass wool boards 12 have excellent sound absorption characteristics. During the propagation process, the noise will be absorbed by the multi-layer composite structure composed of glass wool boards 12, metal plates 1 7 and metal plates 2 8, thereby achieving efficient sound insulation and noise reduction. The switch 14 is used to control the extension and retraction of the telescopic rod 201. When it is necessary to adjust the position of the sound insulation structure or adjust the vibration reduction effect, the telescopic rod 201 can be extended or shortened by operating the switch 14.

[0041] Reference Figure 1 and Figure 4 The shock absorption mechanism 2 includes multiple telescopic rods 201. These rods 201 can extend and retract according to external vibrations, adjusting their length to adapt to different vibration amplitudes. One end of each telescopic rod 201 is fixedly connected to one side of a corresponding glass wool board 12, transmitting the vibration received by the glass wool board 12 to the telescopic rod 201, thus conducting the vibration energy. The other end of each telescopic rod 201 is fixedly connected to a corresponding U-shaped plate 202. Circular grooves 203 are formed at both ends of adjacent sides of the two U-shaped plates 202. These grooves 203 provide installation positions for springs 204, ensuring their stable function. Springs 204 are fixedly connected inside each of the multiple circular grooves 203, absorbing and buffering vibration energy through their elastic deformation. To effectively reduce the propagation of vibration, the other ends of multiple springs 204 are fixedly connected to corresponding damping plates 205, which transmit the vibration buffered by the springs 204 to the damping plates 205 for final vibration dispersion. Limiting grooves 19 are provided on the front and rear sides of the interior of the two U-shaped plates 202. The limiting grooves 19 restrict the movement range of the damping plates 205 to prevent excessive displacement of the damping plates 205 during vibration. Limiting blocks 20 are fixedly connected to the front and rear sides of the two damping plates 205. The limiting blocks 20 cooperate with the limiting grooves 19 to ensure that the damping plates 205 move within the specified range. Multiple limiting blocks 20 are slidably connected to the interior of the corresponding limiting grooves 19, so that the damping plates 205 can slide flexibly within the limited range and stably perform vibration damping work.

[0042] Specifically, when the power plant equipment installed in the mounting slot 13 vibrates during operation, the telescopic rod 201 pushes the U-shaped plate 202 towards the center according to the size of the equipment, so that the two damping plates 205 clamp the equipment. At this time, the vibration is transmitted to the damping plate 205, and the damping plate 205 compresses the spring 204, causing it to contract into the circular groove 203, which causes the spring 204 to deform. The spring 204 has good elastic potential energy, which can absorb and buffer the energy of the vibration. During the vibration reduction process, the damping plate 205 is prevented from excessive displacement, ensuring that the vibration reduction mechanism 2 operates stably in the vibration environment.

[0043] Reference Figure 1 , Figure 2 and Figure 5The base 1 has movable grooves 15 on both the front and rear sides of its top. The movable grooves 15 provide guide tracks for the movement of the U-shaped plate 202, allowing the U-shaped plate 202 to move in a specific direction on the top of the base 1. Movable blocks 16 are fixedly connected to the front and rear sides of the bottom of the two U-shaped plates 202. Protective plates 17 are provided on the front sides of the two metal plates 7. The protective plates 17 can block the collision and scratch of external objects on the metal plates 7, protect the metal plates 7 from damage, and extend their service life. Protective grooves 18 are provided on the rear sides of the two protective plates 17. The protective grooves 18 are used to slide and connect with the front outer wall of the metal plates 7, which facilitates the installation and removal of the protective plates 17 and makes it convenient to maintain or replace the protective plates 17. The outer walls of the multiple fixing bolts 10 are slidably connected with pads. The pads 21 and shims 21 increase the contact area between the fixing bolts 10 and the second metal plate 8, dispersing the pressure generated when the fixing bolts 10 are tightened, and preventing the surface of the second metal plate 8 from deforming or being damaged due to excessive local pressure. One side of each of the multiple shims 21 is respectively attached to one side of the corresponding second metal plate 8, so that the shims 21 can act tightly on the second metal plate 8 and better perform the function of dispersing pressure. One end of each of the multiple fixing bolts 10 passes through the fixing groove 9 in sequence and is rotatably connected to the inside of the corresponding fixing hole 11. Through this connection method, the first metal plate 7 and the second metal plate 8 are firmly fixed together, ensuring the overall stability of the sound insulation structure. The size of the fixing bolts 10 and the fixing holes 11 are matched to ensure the tightness and reliability of the fixed connection.

[0044] Specifically, the movable block 16, which is fixedly connected to the front and rear sides of the bottom of the U-shaped plate 202, allows the U-shaped plate 202 to move along the movable groove 15, providing movable space for the shock absorption mechanism 2. This allows for flexible adjustment of the position of the shock absorption mechanism 2 in different usage scenarios, protecting the metal plate 7 from external impacts and scratches, extending its service life. It also increases the contact area between the fixing bolt 10 and the metal plate 8, dispersing pressure when tightening the fixing bolt 10, preventing damage to the surface of the metal plate 8 due to excessive local pressure, and firmly connecting the metal plate 7 and the metal plate 8, ensuring the stability of the sound insulation structure frame and enabling the entire sound insulation structure to withstand certain external forces.

[0045] Working principle: When using the noise control and sound insulation structure for power plants, during installation, the sliding groove 5 on the top of the fixed plate 1 and the sliding groove 6 on the top of the fixed plate 2 are used to flexibly install the metal plate 1 7 and the metal plate 2 8 respectively. The metal plate 1 7 and the metal plate 2 8 can initially block noise. By passing through the fixed groove 9 and turning into the corresponding fixed hole 11 through the fixing bolt 10, the metal plate 1 7 and the metal plate 2 8 can be firmly connected to ensure the stability of the sound insulation structure. Glass wool boards 12 are fixedly connected to the adjacent side of the two metal plates 1 7 and the front side of the metal plate 2 8. The glass wool boards 12 have excellent sound absorption characteristics. During the transmission process, the noise will be absorbed by the multi-layer composite structure composed of glass wool boards 12, metal plates 1 7 and metal plates 2 8, thereby achieving efficient sound insulation and noise reduction.

[0046] Furthermore, when the power plant equipment installed in the mounting slot 13 vibrates during operation, the telescopic rod 201 pushes the U-shaped plate 202 towards the center according to the size of the equipment, so that the two damping plates 205 clamp the equipment. At this time, the vibration is transmitted to the damping plate 205, and the damping plate 205 compresses the spring 204, causing it to contract into the circular groove 203, which causes the spring 204 to deform. The spring 204 has good elastic potential energy and can absorb and buffer the energy of the vibration.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
