Description

Technical Field

[0001] This application relates to the field of covers, and more particularly to a visual cable trench cover. Background Technology

[0002] Substations contain numerous cable trenches, within which high-voltage cables and secondary cables connect to primary equipment, and these trenches are covered. During routine substation operation and maintenance, maintenance personnel need to periodically inspect the interior of these cable trenches.

[0003] Currently, the covers used to seal cable trenches are generally made of acrylic glass, allowing for direct observation of the trench's interior. However, because cable trenches often contain water, and due to temperature variations, fog or condensation can easily form on the inside of the cover, failing to dissipate over time and affecting the visibility of the trench's interior. Utility Model Content

[0004] In order to effectively remove fog and condensation on the inside of the cover plate and improve the observation of the inside of the cable trench, this application provides a visual cable trench cover plate.

[0005] This application provides a visual cable trench cover, which adopts the following technical solution:

[0006] A visual cable trench cover includes a transparent cover body and two graphene heating films. The two graphene heating films are disposed on the lower side of the transparent cover body, and a visible area is formed between the two graphene heating films.

[0007] Optionally, both graphene heating films are arranged along the length of the transparent cover plate body.

[0008] Optionally, a thermally conductive and heat-resistant adhesive layer is provided between each of the graphene heating films and the transparent cover plate body.

[0009] Optionally, the lower side of the transparent cover plate body is provided with a frosted area, which is located on both sides of the visible area, and the frosted area is provided in a one-to-one correspondence with the graphene heating film.

[0010] Optionally, the lower side of the transparent cover plate body is provided with a frosted area, which is located on both sides of the visible area, and the frosted area is provided in a one-to-one correspondence with the graphene heating film.

[0011] Optionally, the lower side of the transparent cover plate body is provided with a frosted area, which is located on both sides of the visible area, and the frosted area is provided in a one-to-one correspondence with the graphene heating film.

[0012] Optionally, the upper side of the transparent cover plate body is provided with an anti-slip film, which is located on both sides of the visible area, and the anti-slip film is provided in a one-to-one correspondence with the graphene heating film.

[0013] Optionally, the edges of the transparent cover body are rounded.

[0014] Optionally, the transparent cover body includes a first glass layer, an intermediate adhesive film layer, and a second glass layer arranged sequentially from top to top.

[0015] Optionally, the upper side of the first glass layer is provided with a transparent self-cleaning coating.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. By using a graphene heating film, when fog or condensation adheres to the inner surface of the transparent cover, the graphene heating film, when connected to an external circuit and turned on, generates a large amount of heat. This causes the inner surface of the transparent cover to heat up rapidly, evaporating the moisture and ensuring the clarity of the cover, thus improving the observation of the cable trench's interior. Since the graphene heating film is opaque, to maximize the visible area of ​​the transparent cover while ensuring efficient heating of its inner surface, this application uses two spaced-apart graphene heating films. The space between the films serves as the visible area for personnel to observe the interior of the cable trench.

[0018] 2. By connecting two graphene heating films in parallel to the controller, the controller can simultaneously control the power supply to both graphene heating films, ensuring defogging efficiency and simplifying the control logic, thus reducing the cost of the control module. On the other hand, the two graphene heating films can work independently, and the failure of one film does not affect the working status of the other, which helps to extend the defogging life of the transparent cover plate.

[0019] 3. By setting the first glass layer, the intermediate film layer and the second glass layer, the transparent cover plate body becomes a laminated glass, which effectively improves the explosion-proof performance of the transparent cover plate body and enhances its safety; in addition, laminated glass has good thermal insulation effect, which can effectively isolate the heat transfer between the upper and lower sides of the transparent cover plate body, so that after the transparent cover plate body is defogged once, the visible area can remain fog-free for a long time, thus achieving energy saving.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail below.

[0026] Example:

[0027] This application discloses a visual cable trench cover. (Refer to...) Figure 1 A visual cable trench cover includes a transparent cover body 1 and two graphene heating films 2. The two graphene heating films 2 are disposed on the lower side of the transparent cover body 1. Both graphene heating films 2 are arranged along the length direction of the transparent cover body 1, and a visible area 3 is formed between the two graphene heating films 2.

[0028] When fog or condensation adheres to the inner surface of the transparent cover body 1, the graphene heating film 2, after being connected to an external circuit and turned on, generates a large amount of heat, causing the inner surface of the transparent cover body 1 to heat up rapidly. This evaporates the moisture on the inner surface of the transparent cover body 1, ensuring the clarity of the transparent cover body 1 and improving the observation effect on the inside of the cable trench. Since the graphene heating film 2 is an opaque object, in order to maximize the visible area of ​​the transparent cover body 1 while ensuring the heating efficiency of the inner surface of the transparent cover body 1, this application provides two spaced graphene heating films 2. The space between the two graphene heating films 2 serves as the visible area 3, allowing personnel to observe the inside of the cable trench.

[0029] Reference Figure 1-2A thermally conductive and heat-resistant adhesive layer 4 is provided between the graphene heating film 2 and the transparent cover plate body 1. In this embodiment, the thermally conductive and heat-resistant adhesive layer 4 is made of silicone glass glue or polyimide glass glue. A frosted area 5 is provided on the lower side of the transparent cover plate body 1, and the frosted area 5 is located on both sides of the visible area 3, with each frosted area 5 corresponding to a graphene heating film 2. Because the surface of the frosted area 5 is frosted, it can effectively enhance the bonding strength between the thermally conductive and heat-resistant adhesive layer 4 and the contact surface of the transparent cover plate body 1, thereby reducing the possibility of the graphene heating film 2 detaching from the transparent cover plate body 1, and ensuring that the inner side of the transparent cover plate body 1 has a stable defogging effect.

[0030] Reference Figure 2-3 An anti-slip film 6 is adhered to the upper side of the transparent cover body 1. The anti-slip film 6 improves the anti-slip effect of the upper side of the transparent cover body 1, preventing pedestrians from slipping and ensuring public safety. To avoid the anti-slip film 6 obstructing the view of the visible area 3, the anti-slip film 6 is set on both sides of the visible area 3, and the anti-slip film 6 is set in a one-to-one correspondence with the graphene heating film 2.

[0031] Reference Figure 1 The edges of the transparent cover body 1 are rounded, which reduces the sharpness of the edges and improves safety. On the other hand, the rounded edges increase the stress area at the edges, preventing the transparent cover body 1 from breaking when subjected to external impact during use and ensuring the service life of the transparent cover body 1.

[0032] Reference Figure 3 The transparent cover body 1 includes a first glass layer 11, an intermediate adhesive film layer 12, and a second glass layer 13 arranged sequentially from top to bottom. This makes the transparent cover body 1 a type of laminated glass, effectively improving its explosion-proof performance and safety. Furthermore, laminated glass has excellent thermal insulation properties, effectively isolating heat transfer between the upper and lower sides of the transparent cover body 1. This allows the visible area 3 to remain fog-free for a longer period after a single defogging operation, achieving energy savings. Since the first glass layer 11 is exposed on the outside of the cable trench, a transparent self-cleaning coating 14 is provided on its upper side to improve its dustproof effect. In this embodiment, the transparent self-cleaning coating 14 is a transparent superhydrophilic coating; after being washed by road surface water, dirt adhering to its surface can be quickly peeled off, achieving a self-cleaning effect.

[0033] Reference Figure 4The visualized cable trench cover also includes a controller 7, with two graphene heating films 2 connected in parallel and electrically connected to the output of the controller 7. In this embodiment, the rated operating voltage of each graphene heating film 2 is DC 24V. Thus, on the one hand, the controller 7 can simultaneously and centrally control the power supply to and from the two graphene heating films 2, ensuring defogging efficiency, and the control logic is simple, reducing the cost of the control module; on the other hand, the two graphene heating films 2 can work independently, and the damage to one does not affect the working state of the other, which helps extend the defogging life of the transparent cover body 1.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
