Description
integrally pressed fiberglass communication well Technical Field
[0001] This utility model relates to the field of fiberglass communication well technology, and more specifically to a fiberglass communication well that is integrally pressed and molded. Background Technology
[0002] With the rapid development of communication technology, FRP (fiberglass reinforced plastic) communication wells, as an important component of communication network infrastructure, play a crucial role in protecting communication cables, preventing groundwater infiltration, and extending cable lifespan through their sealing performance. However, traditional FRP communication wells have some shortcomings in their sealing design, mainly in the following aspects:
[0003] 1. Simple Sealing Structure: Traditional FRP communication wells typically rely on simple rubber sealing rings for sealing. This method is prone to deterioration in sealing performance over long-term use due to aging, deformation, or improper installation. In some designs, the well cover is only connected to the well body by bolts, and the sealing performance depends on the tightness of the bolts. Once the bolts loosen or the sealing ring is damaged, leakage is likely to occur.
[0004] 2. The contradiction between sealing and opening: To improve sealing, some manhole covers are designed as a single piece of molded material. However, this design may make the cover difficult to open, increasing maintenance difficulty. While some designs employ double-layer covers or complex sealing structures, these designs often increase the complexity of installation and maintenance, and in actual use, improper installation can easily affect the sealing effect.
[0005] 3. Insufficient environmental adaptability: In complex outdoor environments, such as high humidity and high corrosiveness, the durability of traditional sealing structures is poor, easily leading to seal failure. Some sealing designs fail to adequately consider the sealing problem between the manhole cover and the road surface, causing rainwater and harmful gases to seep into the manhole through the joint between the manhole cover and the road surface.
[0006] 4. High maintenance costs: In traditional sealing designs, once the sealing ring is damaged, the replacement process is complex, requiring the removal of the manhole cover and even damage to the road surface, increasing maintenance costs. Some sealing structures have complex designs and require high installation precision; if the installation is not done properly, the sealing performance cannot be guaranteed, further increasing the difficulty of maintenance.
[0007] In summary, existing FRP (fiberglass reinforced plastic) communication well sealing designs suffer from insufficient sealing performance, inconvenient maintenance, poor environmental adaptability, and high maintenance costs. Therefore, developing a sealing structure for FRP communication wells that offers high sealing performance, convenient maintenance, strong environmental adaptability, and low cost is of significant practical importance. Summary of the Invention
[0008] In view of this, the present invention provides an integrally pressed fiberglass communication well, which aims to solve the above-mentioned technical problems.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A one-piece molded fiberglass communication well, comprising:
[0011] The well body is integrally pressed and formed, with a wellhead at the top and an annular sealing groove formed at the bottom of the wellhead;
[0012] The cover body includes a lower cover body and an upper cover body. The lower cover body is fastened to the top edge of the annular sealing groove, and an circumferential rubber ring inserted into the annular sealing groove is fixed to the edge of the lower cover body. The upper cover body is fastened to the wellhead and is fastened to the edge of the wellhead by bolts. Multiple springs are fixedly connected between the bottom surface of the upper cover body and the top edge of the lower cover body. An adjustment assembly is connected between the upper cover body and the lower cover body, and the adjustment assembly can adjust the up and down movement of the lower cover body.
[0013] Through the above technical solution, the well body of this utility model is integrally pressed and formed, resulting in a more robust structure that effectively prevents deformation, improves the stability and service life of the well body, and reduces sealing risks caused by splicing or welding processes. The annular sealing groove and the circumferential rubber ring fixed to the edge of the lower cover cooperate to form a double sealing structure. The rubber ring is compressed within the annular sealing groove, effectively preventing groundwater from seeping into the well, protecting communication cables, and improving sealing performance. The cover body adopts a double-layer structure of a lower cover and an upper cover, connected by multiple springs. The spring force continuously applies pressure to the circumferential rubber ring, maintaining a good sealing effect even when the sealing performance decreases due to aging or deformation of the rubber ring. An adjustment component connects the upper and lower covers, allowing adjustment of the lower cover's vertical movement. This allows the lower cover to be adjusted downwards after the circumferential rubber ring ages or wears, further tightening the rubber ring, thereby extending the service life of the sealing structure and reducing maintenance costs.
[0014] Preferably, in the above-mentioned integrally molded fiberglass communication well, the adjustment assembly includes an adjustment screw and guide rods. The top of the adjustment screw is rotatably connected to the upper cover, and the bolt head of the adjustment screw is exposed. The threaded shaft of the adjustment screw is threadedly connected to the lower cover and passes through the lower cover. Multiple guide rods are arranged around the adjustment screw. The top of each guide rod is fixed to the bottom surface of the upper cover and slides downwards through the lower cover in a sealing manner. The threaded shaft of the adjustment screw is threadedly connected to the lower cover, and the vertical position of the lower cover can be precisely controlled by rotating the adjustment screw. This threaded connection method is simple to operate, has high adjustment accuracy, and can effectively solve the sealing problem caused by the aging of the rubber ring. Multiple guide rods are arranged around the adjustment screw, with the top of the guide rod fixed to the upper cover and sliding downwards through the lower cover in a sealing manner. The function of the guide rods is to ensure that the lower cover moves smoothly up and down in the vertical direction during adjustment, avoiding skewing or shaking due to the rotation of the adjustment screw, thereby ensuring the stability and reliability of the sealing structure.
[0015] Preferably, in the aforementioned integrally molded fiberglass communication well, the top surface of the upper cover has a countersunk hole corresponding to the adjusting screw. The countersunk hole is used to sink the circular bolt head of the adjusting screw, and the top surface of the circular bolt head has a turning groove. The countersunk hole design allows the bolt head of the adjusting screw to be hidden inside the cover, preventing it from protruding from the cover surface and thus avoiding potential impact or damage to the bolt head during use, improving the aesthetics and safety of the cover. The turning groove on the top surface of the circular bolt head facilitates the use of tools to turn the adjusting screw. The turning groove design makes adjusting the adjusting screw more convenient and quick, improving maintenance efficiency.
[0016] Preferably, in the aforementioned integrally molded fiberglass communication well, a cover is fastened to the top surface of the countersunk hole. The cover further protects the bolt head of the adjusting screw, preventing dust, debris, or rainwater from entering the countersunk hole, thereby extending the service life of the adjusting screw and maintaining the cleanliness and aesthetics of the cover surface.
[0017] Preferably, in the aforementioned integrally molded fiberglass communication well, the threaded connection between the adjusting screw and the lower cover is coated with a sealing oil film. This sealing oil film effectively prevents leakage at the threaded connection, further improving sealing performance, and also provides lubrication, reducing friction between the threads and extending their service life.
[0018] Preferably, in the aforementioned integrally molded fiberglass communication well, a sealing gasket is provided at the interlocking edge between the upper cover and the well opening. The sealing gasket further enhances the sealing performance between the cover and the well opening. The sealing gasket effectively fills the tiny gaps between them, preventing rainwater, groundwater, or harmful gases from seeping into the well through the joint between the cover and the well opening, thereby better protecting the communication cables.
[0019] Preferably, in the aforementioned integrally molded fiberglass communication well, the inner bottom wall of the well body has an upwardly protruding overflow port, which communicates with the outside of the bottom wall of the well body. When excessive water accumulates in the well, the excess water can be drained out through the overflow port, preventing water from soaking the communication cables, thereby improving the drainage performance and safety of the communication well and extending the service life of the cables.
[0020] Preferably, in the aforementioned integrally molded fiberglass communication well, a support plate is fixed to the lower inner side of the well body. The support plate has a through hole in its center, and a water filter screen is installed at the through hole. The support plate serves a protective function, housing the communication pipeline below it. If water accumulates, it will remain below the support plate and will not affect the pipeline. The water filter screen filters impurities in the accumulated water, preventing them from clogging the overflow outlet, ensuring unobstructed drainage, and further improving the protective performance of the communication well.
[0021] Preferably, in the aforementioned integrally molded fiberglass communication well, the support plate is an assembled structure and is fixedly connected to the inner wall of the well body by bolts. This design makes the installation and disassembly of the support plate more convenient and quick, facilitates the maintenance and repair of the communication pipeline below the support plate, and also facilitates the cleaning or replacement of the water filter screen, reducing maintenance costs.
[0022] Preferably, in the aforementioned integrally molded fiberglass communication well, the support plate has an inverted conical structure. This inverted conical structure allows water accumulating below the support plate to flow more smoothly to the center of the support plate and be discharged outside the well through a filter screen and overflow outlet, further improving drainage efficiency and enhancing the communication well's anti-water accumulation performance.
[0023] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an integrally pressed fiberglass communication well, which has the following beneficial effects:
[0024] 1. Enhanced Sealing Performance: Multiple seals are formed through the interlocking of the annular sealing groove and the circumferential rubber ring, the double-layer cover structure, and the sealing gasket between the upper cover and the wellhead. This effectively prevents groundwater, rainwater, and harmful gases from seeping into the well, protecting communication cables. A spring provides continuous pressure, ensuring the circumferential rubber ring fits tightly against the sealing groove. Even if the rubber ring ages or deforms, the seal can be further tightened using the adjustment mechanism, ensuring long-term stable sealing performance.
[0025] 2. Optimized Maintenance Convenience: The design of the adjustment components (including the adjustment screw and guide rod) allows for easy restoration of sealing performance after aging or wear of the sealing elements, eliminating the need for frequent seal replacements and reducing maintenance costs and complexity. Details such as the countersunk hole, screw groove, and snap-on cap make the adjustment screw operation more convenient while protecting it from external interference, ensuring safer and more efficient maintenance.
[0026] 3. Enhanced Environmental Adaptability: The sealing oil film at the threaded connection of the adjusting screw and the corrosion resistance of the overall fiberglass material ensure that the communication well maintains good sealing and structural performance even in complex environments with high humidity and high corrosion. The overflow port and water filter effectively prevent water from soaking the communication cables, while the protective function of the support plate further protects the cables from water and impurities, adapting to different environmental conditions.
[0027] 4. Improved structural stability and service life: Robust and durable, reducing the risk of deformation and leakage, and improving the overall structural stability. Easy to install and maintain, while the inverted cone-shaped structure optimizes drainage efficiency, further extending the service life of the communication well. Attached Figure Description
