Description

Technical Field

[0001] This utility model relates to the field of cable well technology, and in particular to a modular sealing device for cable wells. Background Technology

[0002] Outdoor cable wells are often subject to intrusion from rainwater and external water sources, causing water accumulation inside the wells. Therefore, during or after the construction of cable well projects, before the cables are laid in the cable wiring channels between cable wells, it is necessary to use a sealing device to seal the ports of the cable wiring channels in the cable wells. This is to prevent the water levels between cable wells from being connected through the cable wiring channels, which could lead to water entering multiple or even dozens of cable wells due to water entering one cable well.

[0003] A search revealed a modular sealing device for cable wells in patent document CN222349772U. The device includes a sealing column with a rectangular cavity recessed at its end face. A series of threading modules are inserted into the rectangular cavity. A main pressure half-disc and a secondary pressure half-disc are symmetrically pressed onto the end face of the sealing column outside the rectangular cavity. The main and secondary pressure half-discs have opposing triangular openings at their respective disc bodies, which are vertically connected to the opening of the rectangular cavity. The neatly arranged threading modules inside the sealing column are symmetrically secured to the cables using C-shaped spring seats with elastic rubber structures, achieving an aesthetically pleasing and effective cable arrangement. This facilitates cable location tracking during maintenance. Furthermore, the modular assembly of the threading modules at the sealing column allows for the selection of appropriate modules based on the size of the incoming and outgoing cables. The threading modules can be easily disassembled and reused during maintenance and replacement, resulting in low maintenance costs and meeting the modular sealing requirements for cable wells.

[0004] Based on the above search and combined with existing technology, it was found that the existing modular sealing devices for cable wells can only limit the module on one side where the cable is installed. This means that when the cable needs to be pulled out for maintenance, some components (such as the aforementioned cable threading module and C-shaped spring seat) will be pulled out, causing the module to disintegrate and requiring reinstallation, which increases the workload of maintenance work and is inconvenient to use. In addition, the existing modular sealing devices for cable wells are structurally unstable and will also result in poor sealing effect. Therefore, a modular sealing device for cable wells is needed.

[0027] 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.

[0028] Example: Reference Figures 1-4 The modular sealing device for cable wells shown includes: a limiting frame 1, a plug 2, a conduit 3, a support column 4, and an internal hex bolt 5;

[0029] The limiting frame 1 is a hollow frame. The middle part of the limiting frame 1 forms a solid body, and the outer part forms a ring body that adapts to the cable well. There are two limiting frames 1, which are set at intervals.

[0030] The plug 2 is a block with a fan-shaped top section. The upper and lower ends of the plug 2 abut against the two limiting frames 1 respectively. Multiple plugs 2 are arranged and distributed in a circular array along the middle axis of the limiting frame 1. Multiple plugs 2 together form a cylinder.

[0031] The conduit 3 is detachably fixed to the plug 2 by a threaded structure. The conduit 3 vertically penetrates the plug 2, and a conduit hole 31 for the cable to pass through is opened in the middle of the conduit 3. Multiple conduits 3 are provided and correspond to multiple plugs 2 respectively.

[0032] The lower end of the support column 4 is fixed to the lower limit frame 1, and the upper end of the support column 4 is detachably fixed to the upper limit frame 1 by means of internal hex bolts 5.

[0033] The frames of the two limiting frames 1 are both abutted against the upper and lower ends of the plug 2, and both correspond to the side wall positions where the two plugs 2 are in contact with each other.

[0034] Based on the above structure, the plug 2 is clamped and limited by the cooperation of the two limiting frames 1, so that the limiting frames 1 can be used in cable wells to block the cable wells. At the same time, a detachable cable tube 3 is provided and fixed to the plug 2 by a threaded structure. This can not only meet the cable threading requirements, but also ensure that the position of the cable tube 3 is fixed, so that it can remain stable when threading and pulling out cables, which is convenient to use. In addition, the cable tube 3 can be disassembled and replaced, making it more flexible and convenient to use.

[0035] Furthermore, the cross-sectional areas of the multiple plugs 2 are not equal. Some plugs 2 (which may be all or some plugs 2) have mounting holes 21 for inserting the conduit 3, while other plugs 2 (which may be some plugs 2) do not have mounting holes 21 and are only used for sealing.

[0036] The inner diameters of the wire holes 31 on the multiple conduits 3 are different, and the inner diameters of the multiple mounting holes 21 are respectively adapted to the outer diameters of the multiple conduits 3.

[0037] Multiple cable-passing holes 31 with different inner diameters of cable-passing pipes 3 can be used to pass cables of different diameters, thereby further improving the flexibility of the modular sealing device for cable wells and adapting to different cable passing requirements.

[0038] Furthermore, the lower end of the plug 2 has a screw hole 22 with a diameter smaller than that of the mounting hole 21 and connected to the mounting hole 21. The lower end of the conduit 3 is integrally formed with an external threaded tube 32 that is compatible with the screw hole 22. The screw hole 22 and the external threaded tube 32 cooperate to form a threaded structure connecting the plug 2 and the conduit 3.

[0039] Furthermore, the upper end of the support column 4 is provided with a screw groove 41, and the upper limit frame 1 is provided with a stepped hole for the internal hex bolt 5 to pass through. The lower end of the internal hex bolt 5 is screwed into the screw groove 41, and the nut part of the internal hex bolt 5 is embedded in the upper part of the stepped hole of the limit frame 1 and abuts against the limit frame 1.

[0040] Furthermore, the upper end of the conduit 3 has an anti-slip tube head 33 with anti-slip grooves, which makes it easier for workers to twist the conduit 3 and makes it easier to install and remove the conduit 3.

[0041] Furthermore, each of the two limiting frames 1 has a limiting notch 11 on one side that is close to each other. The upper and lower ends of the plug 2 are respectively embedded in the two limiting notches 11, which strengthens the limiting effect of the two limiting frames 1 on the plug 2 and improves the stability of the plug 2 during use.

[0042] The working principle of this utility model is as follows: In daily use, the operator first installs the lower limiting frame 1 inside the cable well, fixing the outer side of the limiting frame 1 to the inner wall of the cable well to form a seal. Then, multiple suitable plugs 2 are placed in the limiting notches 11 of the lower limiting frame 1, forming a cylinder. Next, a suitable conduit 3 is inserted into the mounting hole 21, and the conduit 3 is fixed to the plugs 2 through the engagement of the external threaded tube 32 and the threaded hole 22. Finally, the upper limiting frame 1 is fastened onto the multiple plugs 2, and then... Tighten the hex bolt 5 to secure the upper limiting bracket 1; through the cooperation of the two limiting brackets 1, the plug 2 is clamped and limited, and the limiting bracket 1 can be used in cable wells to achieve the sealing of cable wells. At the same time, a detachable conduit 3 is set and fixed to the plug 2 through a threaded structure. This can not only meet the cable threading requirements, but also ensure that the position of the conduit 3 is fixed, so that it can remain stable when threading and pulling out cables, which is convenient to use. In addition, the conduit 3 can be disassembled and replaced, making it more flexible and convenient to use.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
