Description

Technical Field

[0001] The utility model relates to the field of long-distance oil and gas pipeline communications, in particular to a termite-proof optical cable wiring device for long-distance oil and gas pipelines. Background Art

[0002] Junction boxes are usually used when connecting long-distance pipeline communication optical cables, and most of the junction boxes are located in manholes (handholes), which are low in terrain and prone to humid environments, which are then attacked by termites. Termites not only build nests inside the junction boxes, but also chew on the cable sheaths and insulation layers, leading to serious consequences such as cable breakage and signal interruption. In addition, termites also secrete corrosive substances such as formic acid, which accelerate the corrosion of metal parts and further aggravate the degree of damage to the optical cable junction box. The bottom of the manhole (handhole) is usually sealed. If the manhole (handhole) is not tightly sealed, water is easily accumulated and cannot be removed by itself. Long-term accumulation of water can easily damage the optical cable junction box and even produce toxic gases. Summary of the invention

[0005] Particularly, a first sealing gasket is provided on the top of the manhole body, and a sealing cover is threadedly connected to the top of the manhole body.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] like Figure 1-Figure 4 As shown, a termite-proof optical cable wiring device for long-distance oil and gas pipelines includes a manhole body 1 and a wiring box 2. The manhole body 1 is provided with threading sleeves 101 on both sides, a plurality of drainage holes 102 are provided at the bottom, a filter screen 103 is provided in the drainage holes 102, a drainage pipe 104 connected to the drainage holes 102 is provided at the bottom of the manhole body 1, a cover 105 is installed on the top of the manhole body 1, a first sealing gasket 106 is provided on the top of the manhole body 1, and the cover 105 is threadedly connected to the top of the manhole body 1;

[0019] The junction box 2 is placed in the manhole body 1, and four limit seats 107 are provided at the bottom of the manhole body 1. The four corners of the bottom of the junction box 4 are placed on the limit seats 107 and limited by the limit seats 107. Wire threading holes 201 corresponding to the wire threading sleeve 101 are provided on both sides of the junction box 2. The wire threading sleeve 101 and the wire threading hole 201 are covered with sealing rubber sleeves, and the optical cable passes through the sealing rubber sleeves. A box cover 202 is installed on the top of the junction box 2, and a second sealing gasket 205 is provided on the top of the junction box 2. The box cover 202 is hinged on one side of the top of the junction box 2, and a movable plate 204 is provided on the side away from the hinge. The movable plate 204 is fixed to the junction box 2 by bolts. A side grid 203 is provided on the outside of the junction box 2 and the box cover 202. The inner and outer walls of the junction box 2 and the box cover 202 are coated with a layer of anti-termite agent, and a number of desiccant bags are placed inside the junction box 2.

[0020] Specifically, the agent of the anti-termite agent layer is one of 2.5% cypermethrin microemulsion with a concentration of 156 mg / L or more, 5% cypermethrin water emulsion with a concentration of 500 mg / L or more, and 10% cypermethrin microcapsule suspension with a concentration of 312 mg / L or more; the anti-termite agent is coated on the inner and outer walls of the junction box 2, which can kill and repel termites.

[0021] Specifically, by providing a drainage hole 102 and a drainage pipe 104 at the bottom of the manhole body 1, the manhole body 1 can drain the accumulated water by itself, keep the interior dry, change the humid environment inside the manhole body 1, create an environment that is not conducive to the survival of termites, and at the same time, rainwater and accumulated water are drained away in time to avoid contact with the optical cable. At the same time, when mud is found during the inspection process, it can be cleaned through the drainage hole 102.

[0022] Specifically, the grid 203 is crack-resistant and protects the junction box 2. The grid 203 is made of a material that can resist secretions deposited by termites, such as stainless steel. The hardness of stainless steel is sufficient to prevent it from being corroded by termites. The size of the holes on the grid 203 is smaller than the size of the termite head.

The threading sleeve 102 and the threading hole 201 are covered with a sealing rubber sleeve. The optical cable is passed through the threading sleeve 101 and the sealing rubber sleeve on the threading hole 201, and connected inside the junction box 2. The sealing rubber sleeve can be sealed with epoxy resin, and then the box cover 202 and the cover 105 are closed. When there is water inside, it can be drained through the drainage hole 102 and the drainage pipe 104. The manhole body 1 of the utility model is convenient for self-draining of collected water and keeping the interior dry. The junction box 2 has an anti-termite effect, has a good overall protection effect on the optical cable wiring position, and is easy to use.

[0024] The manhole of the utility model is convenient for draining the accumulated water by itself, keeping the interior dry, forming an environment that is not conducive to the survival of termites. The junction box 2 has the effect of killing and driving away termites. The manhole and the junction box 2 have good sealing and waterproof effects, have good overall protection effect on the optical cable, and are easy to use.
