Description
Technical field
The utility model relates to coal mining field.Be specifically related to underground coal mine air duct tailrace.
Background technology
The air duct of underground coal mine ventilation system is hung above stringing and top, tunnel side, and employee is when air duct discharges water, not easy to operate, need stop stringing, and impact is produced.
Utility model content
The utility model provide a kind of reasonable in design simple, without the need to stopping stringing, ascend operation, stand in air inlet channel below air duct just operable underground coal mine air duct tailrace.
In order to achieve the above object, the utility model has following technical scheme:
The utility model underground coal mine air duct tailrace, tailrace is fixedly connected with hollow wood cylinder by a bolt, tailrace is a short tube, described short tube is divided into two hemizonids, and a hemizonid is rotor, and second half ring body is fixed body, described rotor is rotationally connected by a turning cylinder and fixed body, the medial surface of described rotor is fixedly connected with an annulus, described fixed body is provided with a through hole with annulus correspondence position, separately have a nylon rope to be connected with annulus through through hole.
Further, the through hole lower limb on described fixed body is light face.
Further, described short tube is galvanized pipe.
Further, described hollow wood tube length 1.5m, interior diameter is 25mm.
Owing to taking above technical scheme, the utility model has the advantage of:
The utility model structure is simple, and cost of manufacture is low; Operating personnel may stand in air inlet channel below air duct, use tailrace just can directly discharge water, without the need to stopping stringing, ascend operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1, hollow wood cylinder 2, nylon rope 3, fixed body 4, rotor 5, bolt
Detailed description of the invention
Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.
See Fig. 1, the utility model underground coal mine air duct tailrace, tailrace is by a bolt and a long 1.5m, interior diameter is that the hollow wood cylinder 1 of 25mm is fixedly connected with, tailrace is a short tube, this short tube is a galvanized pipe, short tube is divided into two hemizonids, a hemizonid is rotor 4, second half ring body is fixed body 3, described rotor 4 is rotationally connected by a turning cylinder (not shown) and fixed body 3, the medial surface of described rotor 4 is fixedly connected with an annulus, described fixed body is provided with a through hole with annulus correspondence position, a nylon rope 2 is separately had to be connected with annulus through through hole, through hole lower limb on fixed body 3 is light face.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
