Description

Technical Field

[0001] The utility model relates to the technical field of cable trenches, in particular to a cable trench cover plate made of composite material with strong corrosion resistance. Background Art

[0002] The cable trench is an underground pipeline used to lay and replace power or telecommunication cable facilities. It is also the enclosure structure of the laid cable facilities. The main function of the cable trench is to provide a safe, clean and easy-to-maintain laying channel for the cables. It can also prevent the occurrence of cable aging, short circuit, overheating and other problems. In addition, the cable trench can also reduce the weight burden of the cable itself and extend the service life of the cable. During the construction process, the cable trench can also reduce ground excavation and protect against damage.

[0003] Cable trench covers are generally required to protect the cable facilities in the cable trench and prevent people or objects from falling in. They can also beautify the environment. Cable trench covers are usually detachable, which is convenient for cable maintenance and inspection. When the cable fails or needs maintenance, the cable trench cover can be easily removed to repair and inspect the cable, saving time and labor costs and improving work efficiency.

[0004] The existing Chinese patent with announcement number CN204578037U discloses a cable trench cover, including a support frame, a gasket arranged on the lower side of the support frame, and an upper plate body and a lower plate body arranged on the support frame from top to bottom, the support frame is a frame body formed by connecting two cross beams and two longitudinal beams, the inner cavity of the frame body matches the size of the upper plate body and the lower plate body, the cross-sections of the cross beams and the longitudinal beams are both L-shaped, the upper plate body and the lower plate body are embedded in the frame body and form an integral structure with a horizontal surface with the frame body, the upper plate body is evenly provided with a plurality of through holes, the lower plate body is evenly provided with a plurality of air holes, and the aperture of the air holes is smaller than the aperture of the through holes. The cable trench cover described in the utility model is not only light in weight, but also has sufficient mechanical strength, and has good ventilation and heat dissipation performance.

[0005] However, the above-mentioned device has the following disadvantages: the above-mentioned cable trench cover is a whole cover, corresponding to a fixed cable trench, but for a long-distance, continuous cable trench, the above-mentioned cable trench cover does not meet the installation requirements, and a whole cable trench cover needs to be produced for cable trenches of different lengths. For a longer whole cable trench cover, the production and installation process is relatively inconvenient, so the universality and convenience of the above-mentioned cable trench cover are not high.

[0006] Therefore, it is necessary to provide a composite cable trench cover with strong corrosion resistance to solve the above technical problems. Utility Model Content

[0007] The purpose of the utility model is to provide a composite cable trench cover with strong corrosion resistance, which adopts slots, plug plates, reinforcement rods and limit grooves to stably connect and install multiple cable trench cover bodies, thereby achieving convenience during disassembly and maintenance.

[0008] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a corrosion-resistant composite material cable trench cover, comprising a cover body, a slot is provided at one end of the cover body, a plug plate is fixedly installed at the other end of the cover body, a first fixing plate and a second fixing plate are fixedly installed at the bottom end of the cover body, the first fixing plate and the first fixing plate are respectively arranged at the two ends of the cover body, a bolt is threadedly installed on the side wall of the first fixing plate, a threaded hole is provided on the side wall of the second fixing plate, the threaded hole and the bolt are adapted to each other, a magnetic attraction layer is provided inside the slot, the plug plate is magnetically connected to the slot, a plurality of reinforcement rods are fixedly installed on the side wall of the second fixing plate, a plurality of limit grooves are provided on the side wall of the first fixing plate, and the plurality of reinforcement rods and the limit grooves are adapted to each other.

[0009] By adopting the above technical scheme, when it is necessary to install a cover plate for a cable trench with a longer length, the plug plate on the side wall of the cover plate body is inserted into the slot of another cover plate body, and then the bolt on the first fixing plate is connected to the threaded groove on the second fixing plate of the other cover plate body, thereby realizing the connection between the two cover plate bodies. At the same time, the magnetic attraction layer inside the slot and the plug plate are magnetically attracted to each other, thereby increasing the connection stability of the two cover plate bodies. The connection between the reinforcement rod and the limit groove further increases the stability between the two cover plate bodies. The number of cover plate bodies required is determined according to the length of the cable trench, and then through the above operation, multiple cable trench cover plate bodies can be connected and stably installed, thereby realizing convenience during disassembly and maintenance. At the same time, the number of cover plate bodies can be adjusted for cable trenches of different lengths, thereby increasing the practical performance of the device.

[0010] The utility model is further configured as follows: first sealing strips are fixedly installed on both sides of the cover body, a second sealing strip is fixedly installed on the side wall of one end of the cover body close to the second fixed plate, a sealing groove is opened on the top of one end of the cover body close to the first fixed plate, and the second sealing strip and the sealing groove are adapted to each other.

[0011] By adopting the above technical scheme, the first sealing strips on both sides of the cover body can increase the sealing performance between the cover body and the cable trench. The setting of the second sealing strip and the sealing groove can increase the sealing performance between multiple cover bodies. The sealing performance of the device is increased, which can reduce the entry of external dust and rainwater into the cable trench, thereby increasing the protection of the cable trench.

[0012] The utility model is further configured as follows: a plurality of heat dissipation grooves are provided at the bottom end of the cover plate body, and heat dissipation coatings are provided inside the plurality of heat dissipation grooves.

[0013] By adopting the above technical scheme, the heat dissipation coating is an existing technology, and its function is to increase the heat dissipation performance of the surface of an object, so it is not described in detail. Since the cover body is thick, the heat dissipation performance inside the cable trench is not good. Although the heat dissipation groove does not penetrate the top of the cover body, the heat dissipation coating inside the heat dissipation groove can increase the heat dissipation inside the cable trench.

[0014] The utility model is further configured as follows: a plurality of anti-slip protrusions are arranged on the top of the cover body.

[0015] By adopting the above technical solution, the anti-slip protrusions can increase the friction force on the top of the cover body, preventing pedestrians from stepping on the cover body and slipping, thereby increasing the safety performance of the device.

[0016] The utility model is further configured as follows: a wear-resistant coating is provided on the top of the cover plate body.

[0017] By adopting the above technical solution, the material of the wear-resistant coating is quartz sand, which increases the service life of the cover plate body.

[0018] The utility model is further configured as follows: a cover opening hole is provided at the top end of the cover plate body.

[0019] By adopting the above technical solution and setting the cover hole, the cover plate body can be taken out from the inside of the cable trench.

[0020] In summary, the utility model has the following beneficial effects: when it is necessary to install a cover plate on a cable trench with a longer length, insert the plug plate on the side wall of the cover plate body into the slot of another cover plate body, and then connect the bolt on the first fixing plate with the threaded groove on the second fixing plate of the other cover plate body, thereby realizing the connection between the two cover plate bodies. At the same time, the magnetic attraction layer inside the slot and the plug plate are magnetically attracted to each other, thereby increasing the connection stability of the two cover plate bodies. The connection between the reinforcement rod and the limit groove further increases the stability between the two cover plate bodies. The number of cover plate bodies required is determined according to the length of the cable trench, and then through the above operation, multiple cable trench cover plate bodies can be connected and stably installed, thereby realizing convenience during disassembly and maintenance. At the same time, the number of cover plate bodies can be adjusted for cable trenches of different lengths, thereby increasing the practical performance of the device.
