Abstract
The utility model discloses a rapid water injection device used for a monitoring system for an overlying strata water flowing fractured zone. The rapid water injection device comprises a first connecting piece, a second connecting piece and fastening nuts. The first connecting piece is in butt joint with the second connecting piece. The second connecting piece extends out of the fastening nut. A step surface that matches the second connecting piece is arranged inside the fastening nut. The fastening nut is in threaded connection with the first connecting piece. The second connecting piece is connected with a three-way pipe member, and another two branches of the three-way pipe member are respectively connected with a rubber pipe and a well water pipe. The rapid water injection device is reasonable in design and simple in structure, is convenient to operate, enables water injection time during a monitoring process for the overlying strata water flowing fractured zone to be shortened by 2/3, and enables the efficiency to be doubled.
Description
Technical field
The utility model relates to the equipment that a kind of colliery is used for surveying overlying strata band water fissure zone development height, relates in particular to a kind of quick water filling device for overlying strata height of water flowing fractured zone monitoring system.
Background technology
In the mine, especially in the coal mine roof plate that fissure zone is comparatively grown, the mode of normal use water filling wastage detects the development degree in top board crack, just drill to roof by geological drilling rig, to boring a certain section in water filling, water can permeate in roof strata by the crack, when stablizing, flow rate of water flow picks up counting, the flow of (2min) water in time according to the rules, the wastage of water is just judged the development degree in crack in the top board.
In the existing both-end shutoff overlying strata water flowing fractured zone detecting devices, be to advance in boring by geological drilling rig, the water inlet of employing two-way, wherein shutoff capsule one tunnel adopts the water inlet of internal diameter 8mm high-pressure rubber pipe, external control desk valve, another road plugging hole section adopts the drilling rod water inlet of the hollow of geological drilling rig self, boring is outer to link to each other the high-pressure rubber pipe of drilling rod with internal diameter 8mm by a reducer union, high-pressure rubber pipe connects the control desk valve, and do not allow rotation between reducer union and the high-pressure rubber pipe, when reducer union is installed, cause high-pressure rubber pipe to twine easily.In actual mechanical process, wanting to fill with drilling rod needs nearly 30 minutes of time spent, and wherein water injection time accounts for 94% of this working cycle, and work efficiency is low, and more past boring deep required time is more long, and its water injection time shared proportion in working cycle is more big.How to shorten water injection time, become important measures shortening each net cycle time and increase work efficiency.According to the relevant knowledge of permanent orifice outflow problem in the fluid mechanics, flow is to be directly proportional with the cross-sectional area in aperture, how to realize that therefore not waiting the Fast transforms through water pipe is to shorten overlying strata water flowing fractured zone detection time, the key of increasing work efficiency.
