Description

Technical Field

[0001] This utility model belongs to the technical field of concrete cable cover plates, specifically relating to a concrete cable cover plate with a replaceable counterweight structure. Background Technology

[0002] Cable trenches are underground conduits used for laying and replacing power or telecommunications cables. They also serve as the protective structure for the cable installations. These trenches come in rectangular, circular, and arched forms and typically require covers for protection. A search revealed that application number "CN202021075883.X" discloses a method where "under the action of a locking mechanism, the cover is locked to the cable trench and difficult to open. The cover can only be removed by pulling the handle to activate the locking mechanism. During the rainy season, rainwater on the top of the cover enters the guide channel through gaps and flows into the drainage hole, thus seeping into the ground." Rainwater will enter the guide channel through multiple inlet channels and be discharged, effectively draining rainwater near the cable trench. The locking mechanism ensures the cover plate is securely locked to the cable trench, preventing it from being easily opened. Pulling the handle activates the locking mechanism, allowing the cover plate to be removed. During the rainy season, rainwater on the top of the cover plate will enter the guide channel through gaps and flow into the drainage holes, effectively seeping into the ground. Simultaneously, rainwater from the ground will enter the guide channel through multiple inlet channels and be discharged, effectively draining rainwater near the cable trench. However, the above-mentioned comparison document still has the following problems in actual use:

[0003] In actual use, the counterweight structure cannot be replaced, making it unsuitable for different scenarios and lacking versatility. Furthermore, it requires manual lifting with a crowbar, and it is prone to tilting and falling off during lifting, making it inconvenient to lift.

[0004] Therefore, providing a cover plate that enables quick replacement of counterweights and is easy to lift is highly practical. Utility Model Content
