Description

Technical Field

[0001] This invention relates to the fields of power and municipal facilities technology, and specifically to a sealing system for cable trenches and a cover assembly including the system. Background Technology

[0002] Cable trench covers are key components that cover cable trenches, serving load-bearing, protective, and aesthetic purposes. Currently, most common cable trench covers are rectangular plates made of concrete or composite materials, laid directly on the concrete foundation of the cable trench. Adjacent covers are usually connected by a grooved overlap to address waterproofing issues between them.

[0003] However, the inventors discovered that the existing technology has at least the following drawbacks: Due to manufacturing and installation errors, the surface of the concrete foundation of the cable trench inevitably has unevenness, and the cover plate itself may also undergo slight deformation, resulting in gaps between the bottom surface of the cover plate and the concrete foundation. External water (such as rainwater and sprinkler water) can easily seep into the cable trench through these gaps, posing a serious threat to the safe operation of the cables. In addition, the existing gaps can also cause instability after the cover plate is installed, generating noise and shaking when vehicles or pedestrians pass by, affecting the user experience and the long-term structural strength of the cover plate.

[0004] Therefore, there is an urgent need for an improved cover plate system that can effectively seal the gap between the cover plate and the cable trench foundation, and also has the functions of quiet operation and leveling. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cable trench sealing system and cover plate assembly that is simple in structure, easy to install, has a good sealing effect, and can effectively reduce noise.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a cable trench sealing system, comprising: a cover plate body; an elastic sealing strip; and a connecting structure disposed on the bottom surface of the cover plate body for detachably fixing the elastic sealing strip to the cover plate body, and causing a portion of the elastic sealing strip to protrude from the bottom surface of the cover plate body, so that when the cover plate body is installed on the cable trench foundation, the protruding portion forms an elastic sealing contact with the surface of the cable trench foundation.

[0007] Preferably, the connecting structure is a T-groove formed on the bottom surface of the cover plate body, and the elastic sealing strip is provided with a T-shaped head that mates with the T-groove.

[0008] Preferably, the connection structure consists of multiple mounting holes formed on the bottom surface of the cover plate body, and the elastic sealing strip has a protrusion that is interference-fitted with the mounting holes.

[0009] Preferably, the elastic sealing strip is made of rubber, silicone, or EPDM rubber.

[0010] Preferably, the cross-sectional shape of the elastic sealing strip is a hollow tubular shape or a multi-lip shape.

[0011] Preferably, the elastic sealing strip is continuously arranged circumferentially along the bottom surface of the cover plate body.

[0012] Preferably, the elastic sealing strip is distributed intermittently on the bottom surface of the cover plate body.

[0013] In a second aspect, the present invention provides a cable trench cover assembly, comprising a cable trench foundation and at least one cable trench sealing system as described above, wherein the cable trench sealing system is installed on the cable trench foundation via the elastic sealing strip.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Excellent sealing performance: The elastic sealing strip, which protrudes above the bottom of the cover plate, forms a tight elastic contact with the surface of the cable trench foundation, effectively sealing the installation gaps and preventing moisture from seeping into the cable trench.

[0015] 2. Significant noise reduction and shock absorption effect: The elastic sealing strip acts as a buffer layer, absorbing the energy generated by the cover plate due to pressure or vibration, eliminating the "clanging" sound produced when vehicles or pedestrians pass by.

[0016] 3. Automatic leveling function: The elastic sealing strip can compensate for the height difference caused by uneven foundation or deformation of the cover plate, making the cover plate more stable after installation and avoiding tilting and uneven stress.

[0017] 4. Easy installation and reliable connection: The detachable connection structure, such as "T-slot" or "round hole and protrusion", makes the installation and subsequent replacement of the sealing strip very convenient and the connection is firm.

[0018] 5. Wide adaptability: This solution has a simple structure and can be widely used in cable trench covers of various materials, exhibiting good versatility. Attached Figure Description

[0019] Figure 1 This is a three-dimensional exploded view of Embodiment 1 of the present invention.

[0020] Figure 2 This is a three-dimensional exploded view of Embodiment 2 of the present invention.

[0021] Figure 3 This is a cross-sectional schematic diagram of the cable trench sealing system of the present invention in its installed and used state. Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0023] like Figure 1 As shown, this embodiment provides a cable trench sealing system. The system includes a standard-sized composite material cover body 1. Two T-slots 3 extending along the width direction are machined on the bottom surface of the cover body 1.

[0024] Correspondingly, a strip-shaped elastic sealing strip 2 is provided, which is made of EPDM rubber with excellent weather resistance. The upper part of each elastic sealing strip 2 is integrally formed with a T-shaped head 21 that matches the shape of the T-slot 3. During installation, the T-shaped head 21 of the elastic sealing strip 2 is slid into one end of the T-slot 3 to complete the fixation.

[0025] like Figure 3 As shown, when this cover system is placed on the cable trench foundation 5, the protruding elastic sealing strip 2 is compressed under the weight of the cover and the external load. Its elastic deformation not only completely fills the gap between the cover body 1 and the uneven cable trench foundation 5, achieving reliable sealing and waterproofing, but also provides good shock absorption and noise reduction. Example

[0026] like Figure 2 As shown, this embodiment shares the same core concept as Embodiment 1, differing only in the form of the connection structure. In this embodiment, the bottom surface of the cover plate body 1 is pre-formed with multiple evenly distributed circular holes serving as mounting holes 4. The upper surface of the elastic sealing strip 2 is integrally formed with multiple cylindrical protrusions 22 corresponding to the positions of the mounting holes 4. The diameter of the protrusions 22 is slightly larger than the diameter of the mounting holes 4, forming an interference fit. During installation, simply pressing the protrusions 22 into the corresponding mounting holes 4 achieves reliable fixation of the elastic sealing strip 2.

[0027] Regarding the arrangement, the elastic sealing strip 2 can be arranged in parallel as described in Example 1, or it can be distributed in an intermittent dot matrix or short strip shape.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
