Abstract
The invention relates to an airtight box for an intermediate head of a cable. The structure of the airtight box is characterized in that a through hole is formed along the axial direction inside a box body; the through hole is provided with outer edges at the two ends of the box body, and sealing strips are arranged between the outer edges and the cable. The airtight box disclosed by the invention is used for replacing a cable well to protect the intermediate head of the cable, which not only eliminates the cost for building the cable well but also greatly shortens the repair period; the airtight box is convenient to carry, simple to operate, capable of retaining sealing and corrosion resistances and mechanical strength for a long time under the ground, stable in test data and firm in structure, and the materials and manufacturing process satisfy the standards; therefore, the airtight box is worth of popularization and application.
Description
Technical field
The present invention relates to a kind of electric power system auxiliary equipment, relate in particular to a kind of cable intermediate joint stuffing box, belong to electric power application.
Background technology
The fault of cable line generally occurs in terminals place and nonterminal head place; terminals place fault can be made cable termination again; but the fault that approximately has 70%-90% in the failure analysis report of power supply enterprise occurs in nonterminal place; while repairing this fault, must make cable intermediate joint; then build by laying the cable joint that cable shaft is repaired with protection; the expense of building by laying of cable shaft is very high; generally at several ten thousand yuan; bring very large expense expenditure to power supply enterprise; and waste time and energy, labour intensity is large.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of cable intermediate joint stuffing box is provided, solved and while repairing cable mid head in prior art, need build by laying that the cost that cable shaft causes is high, the large problem of intensity.
Technical scheme of the present invention is as follows:
The inside of casing is provided with through hole vertically, and through hole is provided with outer at the two ends of casing, between outer and cable, is provided with sealing strip.
Described casing is made up of upper and lower two housings, and the lower surface of upper shell is provided with groove I vertically, and the upper surface of lower house is provided with groove II vertically, and groove I formation through hole corresponding with groove II, uses bolted between two housings.
Between two described housings, be provided with sealant.
Described groove I and groove II are semicircle, and two semicircle groove I and groove II form manhole, and aperture and the cable size of manhole match.
Described through-hole diameter is less than width and the height of casing.
Described outer equates at the development length of tank ends.
Described outer development length is 100mm.
Advantageous effect of the present invention is as follows:
Can replace cable shaft protection cable intermediate joint, the water resistance of cable intermediate joint stuffing box and mechanical compressive property are better than cable shaft, stuffing box can directly be embedded in underground use, can not be damaged by pressure, also can not be corroded, guarantee the dry intact of cable joint inside, reduce the expense expenditure of building by laying cable shaft, also can greatly shorten the reparation duration of cable joint simultaneously; Easy to carry, simple to operate, can be for a long time in underground maintenance sealing, anticorrosion, mechanical strength.

Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe structure of the present invention in detail.
Embodiment
As shown in Figure 1-2, casing 1 is made up of upper and lower two housings, between two housings, sealant is set after fastening with bolt 2 between two housings; The lower surface of upper shell is provided with semicircle groove I vertically at center, the upper surface of lower house is provided with semicircle groove II vertically at center, two semicircle groove I formation manholes 3 corresponding with groove II, aperture and the cable size of manhole match, and through-hole diameter is less than width and the height of casing; Through hole is provided with two outers 4 equal in length at the two ends of casing, between outer and cable, be provided with sealing strip.
The preferred embodiments of the present invention are that tank material is stainless steel, and model is 301.The long 1900mm of casing apparent size, wide 500mm, high 500mm, manhole size Ф 80mm-200mm, to both sides, each outer length of extending is 100mm to manhole, weight 26kG.
Sealant and sealing strip adopt waterproof gasket cement, and sealant material is polyurethane, and chemical molecular formula is (C10H8N2O2C6H14O3) x, and serviceability temperature-30 of casing ℃ are to 60 ℃, and humidity requirement is less than 85%.
The present invention is easy to carry, simple to operate, and through three tests and visual examination, test data is stable, sound construction, and material and manufacture craft meet standard, obtain the consistent favorable comment of shop floor worker, are worthy of popularization.
