Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiberglass silencing well technology, and more specifically to a high-strength and corrosion-resistant fiberglass silencing well. Background Technology
[0002] In urban infrastructure construction and industrial sectors, various types of wells are widely used, such as municipal drainage wells, water supply wells, power wells, and communication wells. These wells are typically located in areas such as roads, squares, and factory areas. As a key component, the performance and functionality of the well cover directly affect the overall usability of the well and the quality of the surrounding environment.
[0003] Traditional manhole covers have several prominent problems over long-term use. Firstly, many manhole covers are made of materials with insufficient strength and corrosion resistance, making them prone to damage and corrosion, especially in harsh natural or industrial environments. This shortens their lifespan, and frequent replacements not only increase maintenance costs but can also pose a safety threat to pedestrians and vehicles due to missing or damaged covers. Secondly, when vehicles pass over manhole covers or when water flows around them, noise is generated between the cover and its base, as well as within the cover's structure. This noise can cause pollution in areas with high environmental quiet requirements, such as residential areas, hospitals, and schools, interfering with people's normal lives and work.
[0004] To address these issues, the market demand for high-performance manhole covers and silenced manholes is growing. While some current silenced manhole designs alleviate noise problems to some extent, most solutions focus on adding special sound-absorbing materials or employing complex overall manhole structures. However, they often fail to adequately consider sound absorption in the manhole cover area and do not fully utilize the space beneath the cover for targeted structural sound absorption. Furthermore, some sound-absorbing structures lack sufficient strength and corrosion resistance, making it difficult to meet the requirements for high-strength and corrosion-resistant applications. This hinders the ability to ensure both effective sound absorption and the long-term stable and reliable operation of the manhole cover and the entire manhole structure.
[0005] Against this backdrop, a high-strength and corrosion-resistant fiberglass silencing well was designed, with a particular focus on optimizing the silencing structure at the bottom of the well cover. This design effectively reduces the noise generated by the well cover while ensuring that the well cover and well body possess high strength and excellent corrosion resistance. This has become a technical challenge that urgently needs to be overcome in related fields, and it also has significant practical application value and broad development prospects. Utility Model Content
[0006] In view of this, the present invention provides a high-strength and corrosion-resistant fiberglass silencing well, which aims to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A high-strength and corrosion-resistant fiberglass silencing well includes a fiberglass well body and a fiberglass cover connected to the top of the fiberglass well body; it also includes a silencing component disposed between the fiberglass well body and the fiberglass cover.
[0009] The noise reduction assembly includes an integrally formed annular connecting part and a sinking part. The annular connecting part is connected between the fiberglass well body and the fiberglass cover body. The sinking part is located below the fiberglass cover body, and the bottom surface of the sinking part has noise reduction ribs.
[0010] Through the above technical solution, this utility model designs the silencing components as an integrally formed annular connecting part and a settling groove, resulting in good integrity and high connection strength. This effectively enhances the sealing between the manhole cover and the manhole body, preventing water seepage and debris entry. The silencing ribs reduce noise when vehicles pass over the manhole cover or when water flows through it, improving the surrounding environment and reducing noise pollution. The manhole body and cover, made of fiberglass, have excellent corrosion resistance, resisting chemical corrosion in harsh environments and industrial settings, extending service life and reducing maintenance costs.
[0011] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing manhole, a sound-absorbing buffer rubber pad is provided between the annular surface of the annular connecting part and both the fiberglass manhole body and the fiberglass cover. The use of the sound-absorbing buffer rubber pad effectively buffers vibrations generated when vehicles pass by, reduces direct collisions between the manhole cover and the manhole body, and lowers noise. The flexibility and elasticity of the rubber pad can better fill gaps at the connection point, further improving the sealing between the manhole cover and the manhole body, preventing rainwater and sewage infiltration, and protecting the facilities inside the manhole.
[0012] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing manhole, the bolt assembly passes through the fiberglass cover, the annular connecting portion, the silencing buffer rubber pad, and the fiberglass manhole body to achieve a tight connection. The tightening effect of the bolt assembly ensures a tight connection between the fiberglass cover, the silencing assembly, and the fiberglass manhole body, improving the stability of the overall structure and preventing the manhole cover from loosening or shifting. The bolt connection method is simple, reliable, easy to operate, convenient for installation and subsequent maintenance and replacement, reducing construction difficulty and maintenance costs.
[0013] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing well, the silencing ribs include multi-ring annular ribs disposed on the bottom surface of the trough section. The multi-ring annular rib design can more effectively disperse and absorb noise waves, gradually weakening the sound energy through multiple reflections and refractions, thereby further reducing noise and improving the silencing effect. The multi-ring annular ribs increase the structural strength of the trough section, making it more stable under vehicle loads and water flow impacts, and less prone to deformation or damage.
[0014] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing well, the settling tank has an annular step, on which a sound-absorbing plate is fixed. The sound-absorbing plate further absorbs and reflects sound waves, working synergistically with the sound-absorbing ribs to form a multi-layered sound-absorbing structure, more effectively reducing noise. The annular step design provides stable support for the sound-absorbing plate while enhancing the overall rigidity of the settling tank, ensuring good structural performance under stress.
[0015] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing well, an annular rubber gasket is provided between the upper outer wall of the settling tank and the inner wall of the fiberglass well body, and a gap exists between the lower outer wall of the settling tank and the inner wall of the fiberglass well body. The annular rubber gasket effectively seals the upper connection between the settling tank and the fiberglass well body, preventing water ingress and providing a buffering effect to reduce vibration transmission. The lower gap design allows for a certain degree of displacement and deformation, preventing structural damage caused by thermal expansion and contraction or foundation settlement. The presence of the gap allows for a more uniform stress distribution when the settling tank bears loads, reducing localized stress concentration and extending the service life of the structure.
[0016] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing well, the lower sidewall of the settling tank is connected to multiple clamping components, which abut against the inner sidewall of the fiberglass well body. The clamping components tightly abut against the lower sidewall of the settling tank and the inner sidewall of the fiberglass well body, further improving the sealing performance, preventing water and impurities from entering the well from the side, and also enhancing the connection stability between the settling tank and the well body, thus improving the overall structural load-bearing capacity. By adjusting the position and number of the clamping components, the silencing components can be better adapted to fiberglass well bodies of different sizes and shapes, improving the product's versatility and applicability.
[0017] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing well, the tightening assembly includes a bolt rod and a rubber head. The bolt rod is threadedly connected to the lower sidewall of the settling tank, and the rubber head is fixed to the end of the bolt rod and abuts against the inner sidewall of the fiberglass well body. The threaded connection between the bolt rod and the settling tank provides a reliable mechanical connection, ensuring the stability and adjustability of the tightening assembly. The rubber head abuts against the inner sidewall of the fiberglass well body, increasing friction and sealing, preventing the tightening assembly from sliding or loosening. The use of the rubber head avoids direct contact between the bolt rod and the fiberglass well body, reducing wear and scratches on the well body surface, extending the service life of the well body, and maintaining a good sealing effect.
[0018] Preferably, in the aforementioned high-strength, corrosion-resistant fiberglass silencing well, a drainage hole is provided on the settling tank. The drainage hole design allows for the timely drainage of rainwater or sewage accumulated in the settling tank, preventing water buildup within the silencing components and avoiding impacts on the silencing effect and damage to the internal structure. It also reduces the risk of corrosion to the well body and cover from water accumulation. By draining water, a dry environment is maintained inside the silencing components and the well body, helping to maintain the strength and corrosion resistance of the fiberglass material and ensuring the long-term stable operation of the entire silencing well.
[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a high-strength and corrosion-resistant fiberglass silencing well, which has the following beneficial effects:
[0020] 1. Structural Stability: The high strength and stability of the entire silencer structure are ensured by the special design of the fiberglass manhole body and cover combined with the silencing components, as well as the tight connection of the bolted components, enabling it to withstand vehicle loads and external impacts. Design details such as multi-ring ribs, ring steps, and tightening components enhance the connection strength between the silencing components and the manhole body, further improving the overall structural stability and load-bearing capacity.
[0021] 2. Noise Reduction Effect: The comprehensive use of various noise reduction structures, such as noise-reducing ribs, noise-reducing plates, and noise-reducing buffer rubber pads, effectively reduces the collision noise between the manhole cover and the manhole body, as well as the noise generated by water flow impact, significantly improving the surrounding environment and reducing noise pollution. The multi-layered noise reduction structure design allows sound waves to be continuously absorbed, reflected, and refracted during propagation, gradually weakening the sound energy and thus achieving a better noise reduction effect.
[0022] 3. Corrosion Resistance: The well body and cover are made of fiberglass, giving them excellent corrosion resistance. They can withstand the erosion of chemicals in harsh natural and industrial environments, extending service life and reducing maintenance costs. The use of non-metallic components such as rubber heads also avoids electrochemical corrosion between different materials, further enhancing the overall corrosion resistance of the device.
[0023] 4. Sealing performance: The rational layout of sealing components such as sound-absorbing buffer rubber pads and annular rubber pads effectively prevents the penetration of rainwater, sewage, and impurities, protecting the facilities inside the well and improving the sealing performance between the well cover and the well body. The tight contact between the tightening components and the inner wall of the fiberglass well body further enhances the sealing effect and ensures the airtightness of the space under the well cover.
[0024] 5. Drainage performance: The drainage holes on the settling tank can promptly drain accumulated rainwater or sewage, preventing water from accumulating inside the silencing components, thus avoiding affecting the silencing effect and damaging the internal structure. It also reduces the risk of corrosion to the well body and cover from accumulated water. The gap design allows the settling tank to better adapt to water flow during drainage, preventing blockages and improving drainage efficiency.
[0025] 6. Installation and Maintenance: The bolt connection method is simple, reliable, and easy to operate, facilitating installation and subsequent maintenance and replacement, thus reducing construction difficulty and maintenance costs. The adjustability of the clamping component allows the silencing assembly to adapt to FRP well bodies of different sizes and shapes, improving the product's versatility and applicability, and facilitating installation and use in various scenarios.
[0026] 7. Overall Performance: This FRP (fiberglass reinforced plastic) silencing manhole, while ensuring high strength and corrosion resistance, optimizes the sound-absorbing structure at the bottom of the cover, achieving excellent noise reduction. It overcomes the shortcomings of traditional manhole covers in terms of noise and durability, meeting market demand for high-performance manhole covers and silencing manholes. The synergistic effect of various design details enables this FRP silencing manhole to operate stably and reliably for a long time in practical applications, providing a high-quality and efficient solution for urban infrastructure construction and industrial sectors, with significant economic and social benefits.

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] See appendix Figure 1 To be continued Figure 4 This utility model discloses a high-strength and corrosion-resistant fiberglass silencing well, including a fiberglass well body 1 and a fiberglass cover 2 connected to the top of the fiberglass well body 1; it also includes a silencing component 3 disposed between the fiberglass well body 1 and the fiberglass cover 2.
[0040] The noise reduction component 3 includes an integrally formed annular connecting part 31 and a sinking part 32. The annular connecting part 31 is connected between the fiberglass well body 1 and the fiberglass cover body 2. The sinking part 32 is located below the fiberglass cover body 2. The bottom surface of the sinking part 32 has a noise reduction rib plate 321.
[0041] To further optimize the above technical solution, a sound-absorbing buffer rubber pad 33 is provided between the annular surface of the annular connecting part 31 and the fiberglass well body 1 and the fiberglass cover 2.
[0042] To further optimize the above technical solution, the bolt assembly 4 passes through the fiberglass cover 2, the annular connection part 31, the sound-absorbing buffer rubber pad 33 and the fiberglass well body 1 to achieve a tight connection.
[0043] To further optimize the above technical solution, the sound-absorbing rib plate 321 includes a multi-ring annular rib plate 3211 disposed on the bottom surface of the trough of the settling trough 32.
[0044] To further optimize the above technical solution, the settling tank 32 has an annular step 322, and a sound-absorbing plate 34 is fixed on the annular step 322.
[0045] To further optimize the above technical solution, an annular rubber pad 35 is provided between the upper outer wall of the settling tank 32 and the inner wall of the fiberglass well body 1, and there is a gap between the lower outer wall of the settling tank 32 and the inner wall of the fiberglass well body 1.
[0046] To further optimize the above technical solution, the lower sidewall of the settling tank 32 is connected with multiple clamping components 36, which abut against the inner sidewall of the fiberglass well body 1.
[0047] To further optimize the above technical solution, the tightening component 36 includes a bolt rod 361 and a rubber head 362; the bolt rod 361 is threadedly connected to the lower side wall of the settling tank 32, and the rubber head 362 is fixed to the end of the bolt rod 361 and abuts against the inner side wall of the fiberglass well body 1.
[0048] To further optimize the above technical solution, a water leakage hole is provided on the settling tank 32.
[0049] The working principle of the noise reduction component 3 is as follows:
[0050] The synergistic noise reduction of the annular connecting part 31 and the submerged part 32: The annular connecting part 31 in the noise reduction assembly 3 tightly connects the fiberglass manhole body 1 and the fiberglass cover 2, while the submerged part 32 is located below the fiberglass cover 2, forming a relatively enclosed space. When a vehicle passes by or an external impact is applied to the fiberglass cover 2, the submerged part 32 can buffer part of the impact force, reducing the impact energy directly transmitted to the manhole body 1. At the same time, the special design inside the submerged part 32 interferes with the sound propagation path, causing sound waves to reflect and interfere within it, thereby dissipating sound wave energy and achieving the effect of reducing noise.
[0051] The sound-absorbing ribs 321 attenuate sound waves: The sound-absorbing ribs 321 on the bottom surface of the sink 32 are composed of multiple ring-shaped ribs 3211. When sound waves enter the sink 32, these ring-shaped ribs 3211 increase the path length of sound wave propagation and cause the sound waves to reflect back and forth between the ribs 3211. During the reflection process, the energy of the sound waves is gradually absorbed and dissipated by the material of the ribs 3211, thereby effectively reducing the propagation of noise. This multi-ring design can produce good sound-absorbing effects for sound waves of different frequencies, especially for mid-to-low frequency noise, which is attenuated more significantly through multiple reflections and path extension.
[0052] The working mechanism of the sound-absorbing and cushioning rubber pad 33:
[0053] Buffering, vibration reduction, and sound insulation: The sound-absorbing buffer rubber pad 33 between the annular connecting part 31 and the fiberglass manhole body 1 and fiberglass cover 2 plays a crucial role in buffering and vibration reduction. When a vehicle drives over the fiberglass cover 2, the rubber pad 33 can elastically deform, absorbing some of the impact energy and reducing the rigid collision between the cover 2 and the manhole body 1, thereby reducing the resulting impact noise. At the same time, the rubber pad 33 also has a certain sound insulation effect, which can prevent the direct transmission of sound between the contact surfaces of the cover 2 and the manhole body 1, further reducing the noise transmission efficiency.
[0054] The fastening and stabilizing function of bolt assembly 4:
[0055] Ensuring structural tightness and stability: Bolt assembly 4 passes through the fiberglass cover 2, annular connection 31, noise-absorbing buffer rubber pad 33, and fiberglass well body 1, tightly fixing these components together. This fastening method not only ensures the stability and robustness of the entire noise-absorbing well structure, but also effectively resists various forces when vehicles frequently pass by or the external environment changes, preventing loosening and displacement between components. This ensures that the noise-absorbing assembly 3 is always in good working condition, maintaining the stability of its noise-absorbing effect.
[0056] Sealing and support functions of clamping assembly 36:
[0057] Lateral support and sealing: The tightening assembly 36 on the lower sidewall of the settling tank 32 consists of a bolt rod 361 and a rubber head 362. The bolt rod 361 is threadedly connected to the settling tank 32, and the rubber head 362 abuts against the inner sidewall of the fiberglass well body 1, thereby applying a lateral tightening force to the settling tank 32. This not only provides stable lateral support for the settling tank 32 and enhances the deformation resistance of the entire structure, but also forms a sealing barrier through the tight contact between the rubber head 362 and the inner wall of the well body 1, preventing external debris, moisture, etc. from entering the silencing well, thus helping to protect the internal silencing assembly 3 and the well body 1 structure and extending their service life.
