Description

Technical Field

[0001] This utility model belongs to the field of noise reduction barrier technology, and in particular relates to a multi-band sound-absorbing barrier for noise reduction in substations. Background Technology

[0002] With the rapid development of modern economy and society, the electricity load is increasing day by day, resulting in higher and higher transmission voltage levels. High-voltage and ultra-high-voltage outdoor substations are becoming more and more common. Since the main transformers and power distribution equipment of outdoor substations are all open, noise sources can spread freely to the outside world. Excessive noise from substations has become an urgent problem that substations need to solve, and it also affects the development of power grid construction to a certain extent.

[0003] Noise control measures are basically implemented by controlling the sound source and the sound propagation path. Among them, source control is the most effective method, but it is difficult and time-consuming. Currently, substations in service mainly adopt noise reduction control along the sound source propagation path. Sound barriers are a commonly used noise reduction measure in substations, but the location of the barriers is relatively fixed, which affects the daily maintenance of the substation. Utility Model Content

[0004] This utility model provides a multi-band sound-absorbing barrier for noise reduction in substations, aiming to solve the problem that the sound barrier mentioned in the background technology is a commonly used noise reduction measure in substations, but the barrier position is relatively fixed, which affects the daily maintenance of the substation.

[0007] Preferably, the base is provided with a guide groove, and a slider is fixed to the bottom of the noise reduction plate. The slider is slidably installed in the guide groove to limit the installation path of the noise reduction plate.

[0008] Preferably, the top of the base is provided with a shock-absorbing pad for supporting the substation to reduce resonance noise, and the bottom of the base is provided with a support leg for supporting the base to assist drainage.

[0009] Preferably, the noise reduction plate consists of a main board slidably mounted on the base, metal plates respectively fixed on both sides of the main board, and sound-absorbing pads for absorbing noise. The metal plates are used to isolate flames, and the main board has holes for assisting in noise absorption.

[0010] Preferably, the bottom of the noise reduction plate is inlaid with ball bearings that contact the top of the base to reduce friction, and the groups of noise reduction plates are provided with sealing gaskets on the sides that are close to each other.

[0011] Preferably, the support leg consists of a threaded cylinder fixed to the bottom of the base, a threaded rod threaded inside the threaded cylinder, and a support plate installed at the bottom of the threaded rod to increase the contact area with the ground.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a multi-band sound-absorbing barrier for noise reduction in substations, such as... Figure 1-4 As shown, the multi-band sound-absorbing barrier for substation noise reduction includes: a base 1 for supporting the substation; noise-reducing panels 2 slidably mounted on the top of the base 1 and arranged in groups around the outside of the substation; an arc-shaped top plate 3 fixed to the top of the noise-reducing panels 2; a support net 4 set on the base 1 for assisting in the output of rainwater; handles 5 installed on the opposite side of the noise-reducing panels 2 to provide operating grip points; and a positioning structure set on the noise-reducing panels 2 to stabilize the protection range of the noise-reducing panels 2.

[0022] In this embodiment, a base 1 provides a stable support foundation for the entire noise reduction barrier, ensuring its secure installation around the substation (the substation in this application is a box-type substation). Noise reduction panels 2, which are slidably mounted on top of the base 1 and arranged in groups around the substation, allow for flexible adjustment of the noise reduction range to meet the noise reduction needs of different substations, effectively reducing noise propagation. An arc-shaped top plate 3 further enhances the noise reduction effect and provides some protection. A support net 4 helps to drain rainwater, preventing rainwater accumulation from damaging the barrier and substation and extending the barrier's service life. A handle 5 provides a gripping point for operators, facilitating the installation, adjustment, and maintenance of the noise reduction panels 2. A positioning structure stabilizes the protection range of the noise reduction panels 2, ensuring the stability and reliability of the noise reduction effect.

[0023] In a further preferred embodiment of the present invention, the positioning structure includes a connecting plate 6 fixed on the noise reduction plate 2 and a fixing bolt 7 threadedly mounted on the connecting plate 6 and threadedly connected to the base 1 for stabilizing the connecting plate 6. The fixing bolt 7 is provided with an adjustment block for providing an operating grip point, and the bottom of the adjustment block is provided with an anti-slip pad that contacts the top of the base 1 to increase friction.

[0024] In this embodiment, by setting the connecting plate 6 and fixing bolts 7, the noise reduction plate 2 can be stably fixed on the base 1, which enhances the structural stability of the entire noise reduction barrier, plays a good positioning role, effectively prevents the noise reduction plate 2 from shifting or shaking, and ensures the durability of the noise reduction effect. By setting the adjusting block on the fixing bolt 7, a convenient operating grip point is provided for the operator, making the installation and removal of the fixing bolt 7 more convenient and quick, and improving work efficiency. By setting the anti-slip pad at the bottom of the adjusting block, the friction between the adjusting block and the top of the base 1 is increased, further improving the stability of the fixing bolt 7, so that the noise reduction plate 2 is not easy to loosen when subjected to external force.

[0025] In a further preferred embodiment of the present invention, the base 1 is provided with a guide groove 8, and the bottom of the noise reduction plate 2 is fixed with a slider 9. The slider 9 is slidably installed in the guide groove 8 to limit the installation path of the noise reduction plate 2.

[0026] In this embodiment, by setting the guide groove 8 and the slider 9, the noise reduction plate 2 can be installed along a predetermined path, which plays a role in positioning and guiding, avoiding deviation or misalignment of the noise reduction plate 2 during installation, and improving installation efficiency and accuracy. The slider 9 slides in the guide groove 8, making the installation process of the noise reduction plate 2 smoother, reducing friction and resistance during installation, and reducing installation difficulty and labor intensity. At the same time, this design also makes the noise reduction plate 2 more convenient in subsequent maintenance and adjustment. The noise reduction plate 2 can be easily moved or replaced as needed, improving the flexibility and maintainability of the entire noise reduction barrier, making the noise reduction work of the substation more efficient and convenient.

[0027] In a further preferred embodiment of the present invention, the top of the base 1 is provided with a shock-absorbing pad 13 for supporting the substation to reduce resonance noise, and the bottom of the base 1 is provided with a support leg for supporting the base 1 to assist drainage.

[0028] In this embodiment, by setting the shock-absorbing pad 13 on the top of the base 1, the substation is effectively supported and the resonance noise is reduced, which plays a good role in shock absorption and buffering, reduces the noise pollution caused by vibration during the operation of the substation, and improves the overall noise reduction performance of the noise reduction barrier. By setting the support leg at the bottom of the base 1, it not only plays the role of stabilizing the support of the base 1, but also helps to realize the drainage function, prevents rainwater from accumulating around the base 1, and avoids equipment damage or safety hazards that may be caused by water accumulation.

[0029] In a further preferred embodiment of the present invention, the noise reduction plate 2 is composed of a main board 10 slidably mounted on the base 1, metal plates 11 respectively fixed on both sides of the main board 10, and sound-absorbing pads 12 for absorbing noise. The metal plates 11 are used to isolate flames, and the main board 10 is provided with holes for auxiliary noise absorption.

[0030] In this embodiment, a noise reduction board 2 is formed by setting a main board 10, a metal plate 11, and a sound-absorbing pad 12, achieving a comprehensive noise reduction and protection effect. The main board 10 provides a stable structural foundation for the noise reduction board 2, and its internal hole design plays an auxiliary role in absorbing noise, enhancing the noise reduction effect. The addition of the metal plate 11 not only isolates the flame and improves the safety of the noise reduction barrier, but also reflects noise to a certain extent, further improving the noise reduction performance. The sound-absorbing pad 12 directly absorbs noise and reduces the propagation of noise. This multi-layered and multi-functional noise reduction board 2 design makes the noise reduction work of the substation more comprehensive and efficient, while ensuring the safe operation of the equipment.

[0031] In a further preferred embodiment of the present invention, the bottom of the noise reduction plate 2 is inlaid with a ball bearing that contacts the top of the base 1 to reduce friction, and the groups of noise reduction plates 2 are provided with sealing gaskets on the sides that are close to each other.

[0032] In this embodiment, by embedding ball bearings at the bottom of the noise reduction plate 2 that contact the top of the base 1, the friction is reduced, making the noise reduction plate 2 slide more smoothly or adjust its position, reducing the difficulty of operation and labor intensity, and also reducing the noise generated by friction. The sealing gaskets on the side of the noise reduction plates 2 arranged in groups play a good sealing role, effectively preventing noise from leaking from the gaps between the noise reduction plates 2, and further improving the overall noise reduction performance of the noise reduction barrier.

[0033] In a further preferred embodiment of the present invention, the support leg consists of a threaded cylinder fixed to the bottom of the base 1, a threaded rod threadedly installed inside the threaded cylinder, and a support plate installed at the bottom of the threaded rod to increase the contact area with the ground.

[0034] In this embodiment, by setting a support leg consisting of a threaded cylinder, a threaded rod, and a support plate, the height and stability of the base 1 can be flexibly adjusted. The threaded cylinder is fixed to the bottom of the base 1, providing a stable connection base for the support leg. The threaded rod is threaded inside the threaded cylinder, allowing the height of the support leg to be adjusted according to actual needs, thereby adapting to different terrains and installation environments, and playing a role in height adjustment. The support plate is installed at the bottom of the threaded rod, increasing the contact area with the ground and improving the stability of the support leg, making the entire noise reduction barrier more stable and reliable.

[0035] In summary, compared with related technologies, this device supports the overall structure with a base 1 and has a sliding noise reduction plate 2 that surrounds the substation. This allows for flexible adjustment of the noise reduction range to meet the needs of different substations, effectively reducing noise propagation and facilitating substation maintenance. The positioning structure consisting of a connecting plate 6 and fixing bolts 7 ensures that the noise reduction plate 2 is stably fixed on the base 1, preventing displacement and shaking, and guaranteeing a long-lasting noise reduction effect.
