Description
Technical field
The utility model relates to coal mining apparatus field more particularly to a kind of leting speeper sealing cannula structures.
Background technique
Leting speeper refers to that mine, with advance exploration method, finds out the water-bearing structure of digging front space in mining process
(including water bodys and specific location, the occurrence of conduit pipe etc. such as karst collapse col umn, water-bearing layer, the old dead zones of ponding), and will be in water body
Ponding is unrestrained to be come out, and leting speeper can effectively avoid the generation of coal mine water leak accident.Coal mining execution at present " there is pick that must visit,
First visit and dig afterwards " safety regulation for operations, leting speeper work efficiency and quality directly affect coal mining efficiency and absence from work without reason
Safety, wherein protective sealing casing generally is set in the external of drainage pipeline to prevent drainage pipeline is loaded to be subject to crushing,
For existing sealing cannula structure there are difficult to install, waterproof effect is relatively poor, seriously affects the efficiency and matter of leting speeper operation
Amount.
Utility model content
The purpose of this utility model is to provide a kind of leting speeper sealing cannula structures, to solve the above technical problems.
The utility model uses following technical scheme to achieve the above object:
A kind of leting speeper sealing cannula structure, including fixed plate and sealing casing, it is characterised in that: the sealing casing
More than one, and head and the tail are bolted, wherein the sealing casing for being located at top is connect with fixed plate, the sealing casing
It is welded with spiral rib plate on tube wall, and is respectively arranged with upper terminal pad and lower terminal pad on its top and bottom end, it is described
It is provided with annular groove in upper even disk and lower terminal pad, the annular groove is embedded with waterproof washer, the center of the fixed plate
It is provided with drain-pipe through-hole.
On that basis of the above technical scheme, the thickness of the waterproof washer is greater than twice of annular groove depth.
On that basis of the above technical scheme, the length of the sealing casing is 3M.
On that basis of the above technical scheme, the diameter of the spiral rib plate is greater than the diameter of upper terminal pad and lower terminal pad.
On that basis of the above technical scheme, the upper surface and lower end surface of the drain-pipe through-hole offer annular groove, and
And it is provided with waterproof washer in a ring groove.
On that basis of the above technical scheme, the sealing casing is connect with bolt of fixing plate.
Compared with prior art, the utility model has the advantage that the structure design of the utility model is reasonable, cost
It is low；Sealing casing is designed using spiral rib plate, easy for installation, and can be in close contact with mine hole, and stability is good；Using combination
When design, be readily transported and underground work, length adjustment be flexible；Equipped with waterproof washer, good water-proof effect.
