Protection structure for preventing water and soil erosion of cable in cable trench and production method thereof

Abstract

The invention discloses a protection structure for preventing water and soil erosion of a cable in a cable trench and a production method thereof. The protection structure comprises a lifting adjusting bracket, a bracket adjusting plate, an adjusting bolt shaft, a compression spring and a cable erecting mechanism; according to the depth of the cable trench and the actual cable erecting height, theposition of an embedded threaded cover in the vertical guide rail is adjusted, and the overall height of a cable erecting mechanism is increased; the erection height of the cable can be flexibly adjusted; the cable is prevented from being soaked in muddy water; meanwhile, in the erecting process of the cable, the cable is wound or penetrates through the inner roller body of an erecting roller, and the cable can be straightened or loosened by adjusting a fastening nut, so that overall installation of the cable is facilitated; the cable penetrates through an adjusting rotating wheel, an inner rotating disc and a guide sleeve in the movable plate of an outer sleeve, so that the cable is convenient to arrange. The area of the cable exposed outside is greatly reduced, and the risk of water andsoil erosion is reduced. The cable is erected orderly, is convenient to arrange and adjust, and is suitable for actual use of most cable trenches.

Description

technical field [0001] The invention relates to the technical field of cable trenches, in particular to a protection structure for cables in cable trenches against soil erosion and a production method thereof. Background technique [0002] Cable trench is an underground pipeline used to place and protect cable facilities, and is an indispensable infrastructure in power plants, substations, municipal engineering and large factories and mines. However, due to terrain or design factors, it is easy to accumulate water in the cable trench during heavy rain or rainy season. If the water level is too high, the cables in the cable trench will be soaked in water for a long time and corroded, which will not only damage the insulation of the cable, but also affect its In severe cases, it will also cause the cable to burst due to water ingress. The cable trenches in the prior art are equipped with drainage structures or drainage systems for drainage, but due to the fixed brackets used f...

However, due to terrain or design factors, it is easy to accumulate water in the cable trench during heavy rain or rainy season. If the water level is too high, the cables in the cable trench will be soaked in water for a long time and corroded, which will not only damage the insulation of the cable, but also affect its In severe cases, it will also cause bursting due to water ingress of the cable. The cable trenches of the prior art are equipped with drainage structures or drainage systems for drainage, but due to the fixed brackets used for erecting cables in the cable trenches, after the installation is completed After experiencing heavy rain or drainage system failure, the drainage speed in the cable trench is slower than the speed of accumulated water, which will cause the water level in the cable trench to continue to rise, and eventually the erection cable will be soaked in muddy water, resulting in soil and water pollution. Corrosion, resulting in damage to cables or corrosion damage to fixing brackets
