Description

Technical Field

[0001] This invention belongs to the field of power cable installation, and more specifically relates to a wire sealing device with memory repair function. Background Technology

[0002] During the installation of power cables or electrical equipment, a large number of cables pass through electrical cabinets. These cables need to be sealed at the cable passage holes in the cabinet to prevent water, moisture, rodents, and insects. Current technology requires removing and resealing the sealing material each time a cable passage hole is replaced, which is cumbersome. Furthermore, these cable passage holes are often located in inconvenient areas, further hindering the installation and maintenance of electrical equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a wire-passing sealing device with memory repair function, which solves the problem in the prior art that the wire-passing hole needs to be sealed every time the wire or cable passes through the equipment.

[0015] To facilitate understanding of the technical solution of the present invention by those skilled in the art, the technical solution of the present invention will now be further described in conjunction with the accompanying drawings.

[0016] like Figures 1 to 4As shown, the present invention provides a wire-sealing device with memory repair function, comprising a first sealing plate 1, a second sealing plate 2, and a third sealing plate 3 arranged sequentially, parallel to each other and closely attached. The first sealing plate 2 and the third sealing plate 3 are respectively provided with a plurality of first and third wire-passing holes, each connected to an elastic first sealing sleeve 4 and a third sealing sleeve 5. Both the first and third sealing sleeves 4 and 5 are funnel-shaped and extend away from the second sealing plate 2. The diameter of the inlet end of the first and third sealing sleeves 4 and 5 is larger than the cable diameter, and the diameter of the outlet end is smaller than the cable diameter. The first and third sealing plates 1 and 3 are respectively provided with clearance holes 10 facing the third wire-passing hole and the first wire-passing hole, respectively. The second sealing plate 2 is provided with an intermediate wire hole 9 adapted to the first wire hole and the third wire hole, and a baffle plate 6 is provided on the intermediate wire hole 9.

[0017] Based on the above technical solution, the funnel-shaped first sealing sleeve 4 and third sealing sleeve 5 have an inlet size larger than the cable diameter and an outlet size smaller than the cable diameter. Because they are elastic, the outlet is expanded when the cable passes through. This ensures that the cable passes through on the one hand, and on the other hand, the sealing sleeve will partially wrap tightly around the outside of the cable passing through it, thus achieving sealing and plugging between the cable hole and the cable.

[0018] Based on the above technical solution, the setting of the second sealing plate and the baffle on the second sealing plate can provide a sealed barrier for the through hole and the sealing sleeve where no cable passes through, thereby improving its waterproof, moisture-proof and rodent-proof capabilities.

[0019] Based on the above technical solution, the relatively arranged second and third sealing plates, as well as the first and third sealing sleeves, facilitate the passage of cables from both sides and make cable threading easier.

[0020] like Figures 1 to 4As shown, in the technical solution of the present invention, the second sealing plate 2 and the baffle 6 are both made of hard rubber. The first sealing plate 1, the third sealing plate 3, the first sealing sleeve 4, and the third sealing sleeve 5 are all made of polyurethane elastomer. The first sealing plate 1 and the first sealing sleeve 4 are integrally formed, and the third sealing plate 3 and the third sealing sleeve 5 are integrally formed. The second sealing plate 2 and the baffle 6 are integrally formed. The second sealing plate 2, made of hard rubber, provides a supporting force for the first sealing plate 1 and the third sealing plate 3, facilitating the installation and fixing of this wire-threading sealing device. It also helps the wire-threading sealing device maintain a fixed shape. When cables pass through different wire-threading holes on this wire-threading sealing device, it also enables wire threading and wiring, avoiding multiple cables from tangling, and facilitating subsequent electrical equipment maintenance and cable replacement. The first sealing plate 1, the third sealing plate 3, the first sealing sleeve 4, and the third sealing sleeve 5 are made of polyurethane elastomer, giving them elasticity, especially the first sealing sleeve 4 and the third sealing sleeve 5. The inlet diameters of the first sealing sleeve 4 and the third sealing sleeve 5 are larger than the cable diameter, while the outlet diameters of the first sealing sleeve and the third sealing sleeve are smaller than the cable diameter. After the cable passes through the sealing sleeve, the sealing sleeve is pushed outward and wraps around the cable, achieving a seal between the cable and the through hole. When replacing the cable, the original cable is pulled out, and the sealing sleeve retracts to its original position. It can be reused, has a long service life, low cost, and facilitates electrical equipment maintenance and cable replacement.

[0021] like Figures 1 to 4 As shown, in the technical solution of the present invention, metal fixing frames 7 are respectively provided on the sides of the first sealing plate 1 and the third sealing plate 3 away from the second sealing plate 2. The two metal fixing frames 7 are fixed to each other, and each of the two metal fixing frames 7 is provided with mounting holes 8 penetrating the two metal fixing frames. The provision of metal fixing frames 7 facilitates the fixing and installation of this wire-passing sealing device.

[0022] In this technical solution, the baffle 6 is composed of several flexible rubber sheets arranged in a fan shape and evenly distributed around the circumference of the central wire hole. The baffle 6 is opened when the cable passes through and returns to its original position after the cable is pulled out, thereby sealing the central wire hole 9 and also sealing the wire holes through which no cable has passed.

[0023] In this technical solution, the first and third sealing plates are coated with a fire-retardant coating on their sides away from the second sealing plate. The fire-retardant coating is sprayed from a ceramizable epoxy resin coating, which comprises 15-42 parts of unmodified epoxy resin, 10-45 parts of nano-silica-modified epoxy resin, 5-10 parts of wollastonite, 10-15 parts of glass powder, 5-10 parts of ammonium polyphosphate, 3-5 parts of mica, 1-3 parts of aluminum hydroxide, and 4-8 parts of antimony trioxide; the mass fraction of silica in the nano-silica-modified epoxy resin is 30-40%. The fire-retardant coating enables this wiring sealing device to have fire resistance. In the event of a fire, the fire-retardant coating can ceramize, preventing the fire from spreading, controlling the fire in a localized location, and quickly extinguishing it, thus protecting the electrical equipment.

[0024] The technical solution of the present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
