Description

Technical Field

[0001] This utility model relates to the field of cable insulation protection technology, specifically to an insulating double-layer hybrid coating sleeve. Background Technology

[0002] By installing insulating sleeves on the surface of cables, both insulation protection and environmental corrosion resistance and mechanical protection can be achieved. However, existing insulating sleeves rely on only a single material (such as epoxy resin or silicone rubber), making it difficult to balance insulation and weather resistance (e.g., epoxy resin has high insulation strength but is prone to embrittlement, while silicone rubber has good weather resistance but low insulation breakdown voltage). In addition, the cross-section of existing insulating sleeves is mainly circular. When used in narrow spaces (such as inside equipment enclosures or wall cable trays), redundant gaps are easily generated between the sleeves and surrounding structures (such as metal frames or other pipelines), resulting in wasted space. Furthermore, when connecting and extending adjacent insulating sleeves, they are mainly fixed by welding or clamps. Although this ensures the strength of the connection, the overall operation is relatively complicated, reducing the convenience of connecting adjacent insulating sleeves.

[0003] Therefore, there is an urgent need for an insulating double-layer hybrid coated sleeve to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: an insulating double-layer hybrid coated sleeve, comprising a sleeve body, wherein the cross-section of the sleeve body is square, and the inner and outer side walls of the sleeve body are respectively provided with a core insulating layer and a functional protective layer, and the sleeve body is provided with a connecting component for connecting adjacent sleeves.

[0005] The inner and outer walls of the sleeve body are provided with grooves to enhance the mechanical interlocking force of the coating material, and the grooves are arranged alternately.

[0006] The connecting assembly includes multiple connecting frames fixedly connected to three side walls of the sleeve body near the connecting end. Each connecting frame has a fixing hole on one side, and a connecting plate is slidably connected to each fixing hole. Insert plates are fixedly connected to the three side walls of the sleeve body away from the connecting frames, and each insert plate has an insertion hole. The sleeve body is provided with a driving assembly for driving each connecting plate.

[0007] Each of the connecting plates has an inclined surface on the side closest to the adjacent sleeve body.

[0008] The drive assembly includes a T-shaped rod fixedly connected to the side of the connecting frame near the fixing hole. A drive plate is slidably connected to the T-shaped rod. One end of the drive plate is connected to the connecting plate. A spring is sleeved on the side wall of the T-shaped rod. The two ends of the spring are respectively connected to the side wall of the T-shaped rod and the drive plate.

[0009] A U-shaped plate is slidably connected to the side wall of the sleeve body, and the end of each drive plate away from the connecting plate is connected to the U-shaped plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model's insulating double-layer hybrid coating sleeve utilizes a core insulating layer and a functional protective layer on the inner and outer surfaces of the sleeve body. The inner layer focuses on insulation strength, while the outer layer emphasizes environmental protection. This dual-layer hybrid coating design addresses the shortcomings of single-material performance, thereby improving the sleeve's insulation and weather resistance during use. Furthermore, the square cross-section of the sleeve body reduces redundant gaps with surrounding structures when used in confined spaces and prevents rolling. Simultaneously, the connecting components ensure strong connections between adjacent sleeves while simplifying the connection and positioning operations compared to existing welding and clamp-type connections, thus improving the ease of connecting adjacent sleeves.

[0017] 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.

[0018] Example 1

[0019] Please see Figures 1-4 The figure shows an insulating double-layer hybrid coating sleeve, including a sleeve body 1 with a square cross-section. The inner and outer side walls of the sleeve body 1 are respectively provided with a core insulating layer 2 and a functional protective layer 3. The sleeve body 1 is provided with a connecting component for connecting adjacent sleeves.

[0020] It should be noted that: through the core insulation layer 2 and functional protective layer 3 on the inner and outer surfaces of the bushing body 1, the inner layer focuses on insulation strength, while the outer layer emphasizes environmental protection. This double-layer hybrid coating collaborative design addresses the shortcomings of single material performance, thereby improving the insulation and weather resistance of the bushing during use. Furthermore, the square cross-section of the bushing body 1 not only reduces redundant gaps with surrounding structures when used in narrow spaces but also prevents rolling. At the same time, the connection components ensure the connection strength between adjacent bushings while simplifying the operation of limiting the connection between adjacent bushings compared to existing welding and clamp connections, thus improving the convenience of connecting adjacent bushings.

[0021] It should be emphasized that: the core insulation layer 2 is a mixture of modified epoxy resin, nano Al2O3 and silane coupling agent, and is coated on the inner wall of the sleeve body 1 by vacuum dip coating; the functional protective layer 3 is a mixture of fluororubber, boron nitride microfiber and carbon black, and is coated on the outer wall of the sleeve body 1 by electrostatic spraying.

[0022] Please see Figure 4 The inner and outer walls of the sleeve body 1 in the figure are provided with grooves 4 for enhancing the mechanical interlocking force of the coating material, and the grooves 4 are arranged in an alternating manner.

[0023] It should be noted that the mechanical bonding force of the coating material on the surface of the sleeve body 1 can be improved by multiple interlocking grooves 4.

[0024] Please see Figure 2 and Figure 3 The connecting components shown in the figure include multiple connecting frames 501 fixedly connected to three side walls of the sleeve body 1 near the connecting end. Each connecting frame 501 has a fixing hole 502 on one side. Each fixing hole 502 is slidably connected to a connecting plate 503. Insert plates 504 are fixedly connected to three side walls of the sleeve body 1 away from the connecting frames 501. Each insert plate 504 has an insertion hole 505. The sleeve body 1 is provided with a driving component for driving each connecting plate 503. Each connecting plate 503 has an inclined surface 506 on the side near the adjacent sleeve body 1.

[0025] It should be noted here that by setting up the connecting components, while ensuring the connection strength of adjacent sleeves, the operation of limiting the connection between adjacent sleeves can be simplified compared with the existing welding and clamp connection, thereby improving the convenience of connecting adjacent sleeves.

[0026] Working principle: When installing protective sleeves on cables, firstly, based on the required cable length, connect two or more sleeve bodies 1 to each other. During the connection process, align the connecting ends of two adjacent sleeve bodies 1 (ideally, install rubber washers at the connecting ends of adjacent sleeve bodies 1), and then push the two adjacent sleeve bodies 1 closer together. As the two sleeve bodies 1 move closer together, when each insert plate 504 is inserted into the connecting frame 501, it will abut against the connecting plate 503. Then, the interaction force of the inclined surface 506 and the guiding force of the fixing hole 502 will... When the connecting plate 503 is pushed away from the insert plate 504, as the two sleeve bodies 1 move closer to each other, when the end faces of the two sleeve bodies 1 abut, the connecting plate 503 will engage with the insertion hole 505 on the insert plate 504. Then, under the elastic force of the spring 603, the connecting plate 503 is pushed into the insertion hole 505. By using the blocking effect of the insertion of the connecting plate 503, the connection limit of the adjacent sleeve bodies 1 is realized. Thus, while ensuring the connection strength of the adjacent sleeves, compared with the existing welding and clamp connection, the operation of limiting the connection of the adjacent sleeves can be simplified, thereby improving the convenience of connecting the adjacent sleeves.

[0027] After the adjacent sleeve body 1 is connected and limited, the cable can be inserted into the sleeve body 1. After the cable is inserted into the sleeve body 1, the sleeve body 1 can be placed at the cable laying location. Since the cross-section of the sleeve body 1 is square, it can not only reduce the redundant gap with the surrounding structure when used in narrow spaces, but also prevent rolling. The inner and outer surfaces of the sleeve body 1 are respectively the core insulation layer 2 and the functional protective layer 3, and are coated with insulating protective coating. This allows the inner layer to focus on insulation strength and the outer layer to focus on environmental protection. The dual-layer hybrid coating collaborative design solves the shortcomings of single material performance, thereby improving the insulation and weather resistance of the sleeve during use.

[0028] Example 2

[0029] Please see Figure 2 and Figure 3This embodiment further illustrates Example 1. The driving assembly shown in the figure includes a T-shaped rod 601 fixedly connected to the side of the connecting frame 501 near the fixing hole 502. The T-shaped rod 601 is slidably connected to a driving plate 602. One end of the driving plate 602 is connected to the connecting plate 503. A spring 603 is sleeved on the side wall of the T-shaped rod 601. The two ends of the spring 603 are respectively connected to the side wall of the T-shaped rod 601 and the driving plate 602.

[0030] It should be noted here that the setting of the drive component facilitates the driving of each connecting plate 503, thereby realizing the release of the connection limit between two adjacent sleeve bodies 1.

[0031] Please see Figure 2 and Figure 3 The sleeve body 1 in the figure is slidably connected to a U-shaped plate 604 on its side wall, and the end of each drive plate 602 away from the connecting plate 503 is connected to the U-shaped plate 604.

[0032] It should be noted here that the U-shaped plate 604 facilitates the synchronous driving of each connecting plate 503, thereby releasing the connection limit of two adjacent sleeve bodies 1.
