Description

Drip vented cable sheath

technical field

The utility model relates to the technical field of protection devices for electric pole pull wires of electric power and communication lines, in particular to a dripping ventilation type pull wire sheath.

Background technique

At present, the use of sealed cable protection sleeves on the cable stays of utility poles has played a protective role to a certain extent, and the phenomenon of guy wires being stolen has been reduced. But backguy is made up of multi-strand steel strands, and when the backguy protective sleeve snaps and engages on the steel strands, its contact part is not tight enough, and there is a certain gap. During heavy rain, due to the high water flow rate, the amount of rainwater entering the cable protective cover along the cable is relatively small, while when it is rainy and continuous, the fine water droplets enter the cable protective cover along with the silt, and accumulate in the lower part of the cable. In the silt section, the air in the sheath is humid, which causes serious corrosion of the guy wire and reduces the service life of the guy wire. When running into strong winds, the backguy is easily interrupted, causing a large area of broken wire accidents, and the consequences are disastrous.

Utility model content

The technical problem to be solved by the utility model is to provide a simple structure, safe and reliable drip-ventilated cable sheath, which can prevent the corrosion of the cable caused by water and sand accumulation in the cable sheath, and ensure the service life of the cable.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a drip ventilating pull wire sheath, including a round tube, characterized in that there is a clamping part on the outer wall of the round tube in the longitudinal direction, and the bottom of the round tube Both sides are respectively provided with at least 6 through ventilation circular holes, and the two sides of the seam are respectively provided with at least 6 dripping circular holes.

A groove with a circular cross-section is provided on one side of the clamping portion, and a convex edge with a circular cross-section matching the other side of the clamping portion matches the groove.

The ventilation round holes have a diameter of 0.8 cm and are symmetrically arranged on both sides of the bottom of the round tube at a longitudinal interval of 5 cm. The dripping round holes have a diameter of 0.6 cm and are symmetrically arranged on both sides of the bottom of the clamping part at a longitudinal interval of 5 cm. side.

The beneficial effect produced by adopting the above-mentioned technical scheme is that: the utility model installs a ventilation circular hole and a dripping circular hole on the original pull wire sheath device. The hole discharges the sediment carried in the rainwater. The utility model maintains good ventilation in the pull wire sheath through the ventilation round hole, avoids a humid environment in the pull wire sheath, so that there is no water or sand in the pull wire sheath. It avoids the corrosion phenomenon of the pull wire, ensures the strength of the pull wire, and prolongs the service life of the pull wire.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is a schematic diagram of the structure of the utility model dripping ventilation type guy wire sheath.

As shown in Figure 1, 1 round pipe, 2 clamping parts, 3 round holes for ventilation, and 4 round holes for dripping water.

Detailed ways

As shown in Fig. 1, a kind of drip ventilated pull wire sheath comprises a round tube 1, which is characterized in that there is a clamping part 2 longitudinally on the outer wall of the round tube 1, and at least two sides of the bottom of the round tube 1 are provided with There are 6 penetrating ventilation round holes 3, and at least 6 dripping round holes 4 are respectively provided on both sides of the clamping part 2. A groove with a circular cross-section is provided on one side of the engaging portion 2 , and a convex edge with a circular cross-section matching the other side of the engaging portion 2 is provided with the groove. The ventilation round holes 3 have a diameter of 0.8 cm and are symmetrically arranged on both sides of the bottom of the round tube 1 at a longitudinal interval of 5 cm. The dripping round holes 4 have a diameter of 0.6 cm and are symmetrically arranged at the clamping part at a longitudinal interval of 5 cm. 2 on both sides of the bottom.

For the modification of the ventilating round hole of the utility model, at the place 30cm away from the ground on both sides of the bottom of the pull wire sheath, left and right symmetrical round holes with a diameter of 0.8cm are drilled, and the longitudinal distance of the round holes is 5cm, and at least six circles are arranged in sequence from top to bottom. The hole extends to the ground, and the left and right symmetrical round holes form a good ventilation. The modification of the drip hole of the utility model is to drill symmetrical round holes with a diameter of 0.6 cm on both sides of the lower abdomen seam of the pull wire sheath, and the longitudinal distance of the round holes is 5 cm. When rainwater enters the pull wire sheath, it passes through the drip hole Drain the sediment carried by the rainwater.

The utility model installs ventilation round holes and drip round holes on the original pull wire sheath device. When encountering heavy rain or continuous rainy weather, the utility model discharges the sediment carried in the rainwater through the drip round holes. The utility model maintains good ventilation in the cable sheath through the ventilation hole, avoiding the humid environment in the cable sheath, so that there is no water or sand in the cable sheath, avoiding the corrosion of the cable and ensuring the strength of the cable. The service life of the pull wire is extended.
