Abstract
A kind of sealing of hole of the utility model expands ball device, with sealing of hole sphere, sealing of hole sphere is made of two semicircle spheres, and the top of two halves circle sphere is plane, extruding disk is equipped in the top planes of two halves circle sphere, two halves circle sphere and two extruding disks are linked into an integrated entity by a screw rod；The utility model is simple in structure, easy to use, to temporary cable hole carry out sustainability flexible sealing, solve the problems, such as traditional cable hole expand with heat and contract with cold external force cause block it is not tight；Fast Installation dismounting is suitable for interruption sex work, is blocked daily according to job schedule, effectively realizes the purpose of the anti-toy of waterproof；The assistance personnel needed when use are few；Folding and unfolding is convenient, and installation and transportation are convenient, occupy little space, within 10 seconds；No matter landform, weather, expansion whenever and wherever possible uses.
Description
Technical field
The utility model is related to field of electrical equipment, especially a kind of sealing of hole expands ball device.
Background technology
The cable laying of electric system locates below ground level in cable duct of substation, and cable incoming-outgoing cable duct is being connected to
Cable duct switchgear house is passed in and out during electrical equipment（Vertical direction blocks）And high-tension switch cabinet（Horizontal direction）Closure it is non-
It is often important, first, anti-toy enters high-tension apparatus internal short-circuit second is that prevent summer rainfall anomaly rainwater from pouring in down a chimney enters high pressure along cable
Equipment internal short-circuit, gently then causes switch motion, user's dead electricity, heavy then cause ignition of cable, equipment damage.It is multiple in groundwater condition
The miscellaneous and big region of rainfall, every year due to the transformer and distribution power station percolating water of underground caused by cable termination defect or failure it is more normal
See.Under traditional closure situation, since the characteristic of closure cement and the construction quality of each construction team are irregular, envelope
It is easy within a short period of time to occur in Groundwater infiltration cable duct and transformer and distribution power station after the completion of stifled, greatly increases interior humidity, give
The safe operation of power grid brings very big hidden danger.
Substation control buildings high-tension switch cabinet bottom cable cavern generally uses fire-proof mud or lime to be blocked, due to hole
Without any support, a plurality of cable penetrates external force in maintenance process simultaneously to be led to fire prevention calking recess in hole, sinks, is dry for hole bottom
Split, fall off, anti-toy enter, switchboard assembly it is moisture-proof, fire prevention etc. bring security risk, in recent years each substation because
The next line tripping of holes blocking imperfect tape, electric discharge phenomena happen occasionally.And a large amount of manpower and materials are expended every year to power transformation
Hole of standing carries out benefit envelope, results in waste of resources, and is also brought to working site dirty and inconvenient.
Invention content
The purpose of this utility model is improved aiming at disadvantage mentioned above, provides simple in structure, and easy to make, installation is torn open
Unload a kind of quick and convenient, effectively to be blocked to cable cavern sealing of hole expansion ball device.
A kind of sealing of hole of the utility model expands ball device, it is characterised in that：With sealing of hole sphere, sealing of hole sphere is by two
Semicircle sphere is constituted, and the top of two halves circle sphere is plane, and extruding disk is equipped in the top planes of two halves circle sphere,
Two halves circle sphere and two extruding disks are linked into an integrated entity by a screw rod.
The sealing of hole sphere is made of rubber.
Disk, which is squeezed, one of in the two extruding disk is equipped with hook ring.
The utility model is simple in structure, easy to use, carries out sustainability flexible sealing to temporary cable hole, solves
Traditional cable hole external force of expanding with heat and contract with cold causes to block not tight problem；Fast Installation dismounting is suitable for interruption sex work, daily root
It is blocked according to job schedule, effectively realizes the purpose of the anti-toy of waterproof；The assistance personnel needed when use are few；Folding and unfolding is convenient, peace
Convenient transportation is filled, is occupied little space, within 10 seconds；No matter landform, weather, expansion whenever and wherever possible uses.
Description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1- semicircle spheres, 2- squeeze disk, 3- screw rods, 4- hook rings.
Specific implementation mode
Referring to Fig. 1, a kind of sealing of hole of the utility model expands ball device, has sealing of hole sphere, sealing of hole sphere is by two and half
Round sphere 1 is constituted, and the top of two halves circle sphere is plane, is equipped in the top planes of two halves circle sphere and squeezes disk 2,
Two halves circle sphere and two extruding disks are linked into an integrated entity by a screw rod 3；The sealing of hole sphere is made of rubber；Described two
Disk, which is squeezed, one of in extruding disk is equipped with hook ring 4.In use, sealing of hole sphere is put into cable cavern, then lead to
The nut crossed on tightening screw rod makes both ends squeeze disk extruding two halves circle sphere, makes two halves circle sphere reducing to block cable
Hole when taking out sealing of hole sphere, need to only unclamp nut, hold hook ring and just can be taken off sealing of hole sphere.
