Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, specifically a floating device for optical cable junction boxes that is installed in underground pipe wells and adapts to changes in water level through buoyancy. Background Technology

[0002] In underground manholes used in low-voltage electrical engineering, the traditional fixed installation method for fiber optic junction boxes, which involves fixing them to the manhole wall, presents numerous problems. Underground manholes are frequently plagued by water accumulation and fluctuating water levels, making fixed junction boxes susceptible to submersion. This leads to water erosion of the fiber optic connections, causing oxidation and corrosion, increased optical signal transmission loss, and even communication interruptions. Even if not submerged, ground vibrations transmitted through the manhole wall can loosen the fiber optic connections inside the junction box, affecting signal quality. Furthermore, traditional junction boxes use complex installation methods such as screw fixing, making installation and disassembly difficult in the confined space of the manhole, severely impacting construction efficiency and subsequent maintenance, and failing to meet the requirements of low-voltage electrical engineering for stable and convenient fiber optic connections. Utility Model Content

[0003] To address the problem that the traditional fixed installation method of fiber optic splice boxes in the aforementioned underground well scenarios is prone to flooding due to fluctuating water levels, which affects the quality of fiber optic signals, this application provides a floating device for fiber optic splice boxes that adapts to water levels in underground wells. This device improves the adaptability of fiber optic splice boxes to changes in water level, reduces the risk of flooding, and enhances the stability of fiber optic signals.

[0004] The purpose of this utility model is to provide an adaptive water level optical cable junction box floating device, comprising: a buoyancy base, the buoyancy base including an EPP foam sealed float; a universal ball joint mounting base connected above the buoyancy base, a universal ball joint connected to the upper middle part of the universal ball joint mounting base, the other end of the universal ball joint connected to a bearing platform, a wear-resistant silicone shock-absorbing layer provided on the upper part of the bearing platform, and an optical cable junction box connected above the wear-resistant silicone shock-absorbing layer.

[0005] Preferably, a counterweight device is provided in the lower half of the buoyancy base.

[0006] Preferably, the counterweight device is a stainless steel hoop evenly arranged around the circumference of the buoyancy base, and counterweight blocks are evenly arranged around the circumference of the stainless steel hoop.

[0007] Preferably, the support platform is an aluminum platform.

[0008] Preferably, the support platform is surrounded by a splash guard.

[0009] Preferably, the universal ball joint is covered with a silicone waterproof cover.

[0010] Preferably, a V-shaped groove is provided on the bearing platform, the position of the V-shaped groove corresponds to the L-shaped fixing foot of the optical cable junction box, and a spring-type self-locking device is fixedly installed in the V-shaped groove.

[0011] Preferably, the L-shaped fixing foot is a metal foot, and a neodymium magnet positioning block is provided at the entrance of the spring-loaded self-locking device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model's adaptive water level optical cable junction box anti-immersion device uses an EPP foam-sealed float on the buoyancy base to keep the junction box afloat on the water surface, mitigating the risk of flooding and ensuring stable fiber optic connections. A universal ball joint connects the buoyancy base and the support platform, automatically adjusting the platform's angle according to water level fluctuations to maintain horizontality. Combined with a wear-resistant silicone shock-absorbing layer on the upper part of the support platform, this double protection significantly reduces the impact of external vibrations on the optical fiber junction box, lowers the risk of loose fiber optic connections, ensures stable optical signal transmission, enhances the overall stability and reliability of the device, and extends its service life.

[0020] 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.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, an adaptive water level optical cable junction box floating device includes: a buoyancy base 1, the buoyancy base 1 including an EPP foam sealed float, the outer surface of the float being covered with an HDPE waterproof layer to ensure no risk of water leakage in long-term immersion environment; a stainless steel hoop 2 is installed around the lower half of the buoyancy base, and four counterweights 3 are evenly distributed on the hoop, so that the center of gravity of the device is located below the center of buoyancy, forming a stable inverted pendulum structure.

[0022] The buoyancy base 1 is connected to a universal ball joint mounting base 4 above it. Specifically, the universal ball joint mounting base 4 is connected to the top of the buoyancy base 1 by M6 stainless steel bolts. The PTFE cup seat 6 of the universal ball joint 5 is connected to the middle of the base by bolts. The PTFE cup seat is embedded in and connected to a stainless steel ball 7, and the ball and the PTFE cup seat 6 form a low-resistance rotating pair. The universal ball joint 5 is covered with a silicone waterproof cover, and the edge of the waterproof cover is sealed to the base with an O-ring.

[0023] The other end of the universal ball joint 5 is connected to the support platform 8. Specifically, an anodized aluminum alloy plate is used as the support platform 8, and a splash guard 9 is integrally formed around the platform to enhance impact resistance. A silicone shock-absorbing layer 10 is attached to the upper surface of the support platform 8. An optical cable junction box 11 is connected above the wear-resistant silicone shock-absorbing layer 10. Specifically, two V-shaped cross grooves 12 are provided on the support platform 8 for positioning the connection of the optical cable junction box 11. The position of the V-shaped grooves 12 corresponds to the L-shaped fixing feet 13 of the optical cable junction box. The L-shaped fixing feet 13 are provided with locking holes 14, such as... Figure 4 As shown, the L-shaped fixing foot 13 is a metal foot. A spring-loaded self-locking device 15 is provided at the fixing position of the L-shaped fixing foot 13. The spring-loaded self-locking device 15 includes a locking seat 16 and an elastic piece 17. The elastic end of the elastic piece 17 is bent and contacts the locking seat 16. It should be noted that the spring-loaded self-locking device described in this embodiment is a commercially available product of the prior art and does not constitute a disclosure of this application. A neodymium magnet positioning block 18 is provided at the entrance of the spring-loaded self-locking device 15.

[0024] The installation process for this application is as follows:

[0025] Inside the branch shaft of the underground utility tunnel, the assembled floating device is placed on the water surface. The buoyancy base 1 floats automatically and is kept vertical by a counterweight device. The universal ball joint 5 allows the bearing platform 8 to freely adjust its angle within a certain range, keeping the bearing platform 8 as horizontal as possible.

[0026] The operator aligns the optical cable junction box 11 with four L-shaped fixing feet 13 at the bottom with the V-shaped groove 12 of the support platform 8. Under the attraction of the neodymium magnet positioning block 18, the L-shaped fixing feet 13 slide into the V-shaped groove 12 with a certain positioning accuracy, further pushing the junction box to the spring-loaded self-locking device 15, pushing the L-shaped fixing feet 13 into the locking seat 16, so that the elastic sheet 17 deforms under the thrust and rebounds to lock into the locking hole 14 on the L-shaped fixing foot 13.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
