Description

Technical Field

[0001] The utility model relates to the technical field of cable construction, and more specifically, to a waterproof cable trench. Background Art

[0002] With the development of society and industry, the demand for electricity is increasing, and correspondingly, the layout of cables is also increasing. There is high voltage current in the cable, and the cable needs to be protected. The existing practice is to set up a cable trench, in which most of the cables are buried. The cable trench is generally cast and sealed by a sealing cover plate on the upper end surface.

[0003] Publication No. CN206894196U discloses a high-strength and high-sealing cable trench for construction, comprising a cable trench body, a compacted soil layer is arranged at the bottom of the cable trench body, a crushed stone cushion layer is arranged above the compacted soil layer, a plain concrete cushion layer is arranged above the crushed stone cushion layer, a concrete foundation is arranged above the plain concrete cushion layer, and cable trench walls are arranged on both sides of the surface of the concrete foundation. In the above technical scheme, the device is provided with a waterproof layer on the inner side of the cable trench body, and the contact surfaces of the cable trench cover and the cable trench body are provided with sealing pads, so that the waterproof effect of the device is better, which effectively prevents the cable from being corroded due to water ingress in the cable trench body and increases the service life of the cable.

[0004] In the above technical solution, the cable trench cover and the cable trench body are sealed by means of a sealing gasket. The service life of the cable is between 20 and 30 years. During this period, after long-term use, the sealing performance of the sealing gasket is greatly reduced due to aging and other reasons. External rainwater can easily enter the interior of the cable trench body through the gap between the cable trench cover and the cable trench body, causing the cable to be soaked in water and affecting its service life.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0023] A waterproof cable trench, such as Figure 1-Figure 3 As shown, it includes a cable trench body 1, and mutually symmetrical drainage trenches 2 are fixedly connected on both sides of the cable trench body 1. A plurality of cover plates 3 extending to the top of the drainage trench 2 are detachably connected to the top of the cable trench body 1. A plurality of through grooves 4 are opened on both sides of the cover plates 3 near the drainage trench 2. Drainage parts for preventing water leakage at the connection of the cover plates 3 are arranged on the cover plates 3. When it rains, rainwater can be blocked by the cover plates 3 and enter the drainage trench 2 along the through grooves 4. The cable trench body 1 and the drainage trench 2 body are separated from each other, so that rainwater cannot enter the cable trench body 1. The drainage parts can prevent water leakage at the parts connected to the plurality of cover plates 3, so that the cable trench body 1 is kept dry, thereby extending the service life of the cable. The dry environment can maintain the insulation performance of the cable, prevent problems such as insulation reduction or short circuit caused by moisture, and improve the operation rate of the cable.

[0024] Guide plates 5 are fixedly connected to both sides of the cable trench body 1, and an embedding groove 6 is provided on the cover plate 3. The top of the guide plate 5 is clamped in the embedding groove 6. When the water flow at the through groove 4 is slow, the guide plate 5 can intercept the rainwater spreading at the bottom of the cover plate 3 to prevent the rainwater from flowing into the cable trench body 1 along the cover plate 3. The embedding groove 6 can make the connection between the guide plate 5 and the cover plate 3 tighter to prevent rainwater from seeping into the cable trench body 1.

[0025] The drainage component includes a connecting groove 7 and a groove 8 opened on one side of the cover plate 3. One side of the connecting groove 7 is fixedly connected to the side of the cover plate 3 away from the groove 8, and the other side of the connecting groove 7 is clamped in the groove 8 of the adjacent cover plate 3. Both ends of the connecting groove 7 are connected to the drainage groove 2. The connecting groove 7 can intercept water dripping from the gap between the cover plates 3 and the cover plates 3. The connecting groove 7 can be inserted into the groove 8 so that the connecting groove 7 and the cover plate 3 can be tightly connected. The slope of the connecting groove 7 close to the cover plate 3 gradually decreases from the center to the height on both sides, ensuring that rainwater can flow into the drainage ditch 2 along the slope, reducing the time that rainwater stays in the connecting groove 7, preventing rainwater from entering the cable trench body 1, and preventing the cable from getting wet.

[0026] An insulation layer 9 is fixedly connected to the inner wall of the cable trench body 1 . The insulation layer 9 has a heat insulation function. The insulation layer 9 can reduce the temperature change on the surface of the cable trench body 1 and reduce the occurrence of condensed water inside the cable trench body 1 .

[0027] A plurality of cable mounting brackets 10 are fixedly connected to the top of the insulation layer 9. The cable mounting brackets 10 can elevate the cables for installation. When the cable trench body 1 is cracked or leaks other water, a certain distance is maintained between the cables and the bottom surface of the cable trench body 1, thereby preventing the cables from directly contacting water and providing time for repairing the cable trench body 1. A plurality of drying boxes 11 are detachably connected to the inside of the cable trench body 1. The drying boxes 11 are provided with desiccants. The desiccant can absorb water vapor in the air, thereby ensuring that the inside of the cable trench body 1 remains dry.

[0028] The normal use of this utility model is as follows:

[0029] When it rains, most of the rainwater can flow into the drainage ditch 2 along the through groove 4 and be discharged. During the rainfall process, the rainwater flowing in from the gap between the two cover plates 3 can be intercepted by the connecting groove 7 and flows into the drainage ditch 2 along the connecting groove 7, preventing the rainwater from entering the cable trench body 1 and affecting the service life of the cable. The thermal insulation layer 9 on the inner surface of the cable trench body 1 reduces the temperature change on the surface of the cable trench body 1, thereby reducing the occurrence of condensed water, and together with the desiccant, reduces the water vapor inside the cable trench body 1 to ensure the dryness of the interior.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
