Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In order to solve the technical problem that this application will solve, provide a mine infiltration water sample collection system in pit, as in fig. 1 and fig. 2, the device includes: the collecting nozzle 2 is provided with a horn-shaped opening, the collecting nozzle 2 is used for effectively receiving seepage water from the wall of a roadway, and the small-diameter end of the collecting nozzle 2 is connected with one end of the water collecting pipe 3, so that mixed water can conveniently flow into the water collecting pipe 3; the other end of the water collecting pipe 3 is connected with a water conduit 5 with the diameter smaller than that of the water collecting pipe 3 through a reducer union 4; the water guide pipe 9 led out from the free end of the water guide pipe 5 is inserted into the water collecting bottle 92; a grit chamber 7 is arranged in the middle of the water collecting pipe 3, the water collecting pipe 3 and the grit chamber 7 are in a T-shaped three-way structure, and a sand discharge port 71 controlled by a manual valve 8 is arranged at the bottom of the grit chamber 7; a filter screen 6 for preventing the solid mixture from passing through is arranged from the right side of the grit chamber 7 to the top of the water collecting pipe 3; the front end of the water collecting pipe 3 is provided with a front bracket 32 with adjustable height; a rear bracket 51 with the height smaller than that of the front bracket 32 is arranged below the water conduit 5, and the height-adjustable structure of the front bracket 32 adopts a spiral adjusting mode.
The utility model discloses a theory of operation is: firstly, a circular arc surface is ground on the water seepage wall 1, so that the water collecting nozzle 2 is in close contact with the circular arc surface without a gap, and then the front support 32 is adjusted to a position exceeding the rear support 51. Seepage water flows into the water collecting pipe 3 from the water collecting nozzle 2; due to the obstruction and gravity action of the filter screen 6, the solid mixture in the water flow directly enters the grit chamber 7. Because the depth in the grit chamber 7 is great, solid particles such as large-particle silt and small-particle silt directly deposit in the grit chamber 7, most of the upper layer of the grit chamber 7 is suspension liquid with small silt, the suspension liquid slowly flows into the right side of the water collecting pipe 3 through the filtering and penetrating effects of the filter screen 6, and the filtered water passes through the guide of the water guide pipe 5 and enters the water collecting bottle 92 through the water guide pipe 9.
During this operation, the diameter of the penstock 5 is smaller than the function of the collector pipe 3: on the one hand, the filtered water is filled into the water collecting bottle 92 more conveniently, and on the other hand, the water flowing into the water collecting bottle 92 is slowed down, so that small-particle silt cannot be attached to the filter screen 6. When the flow rate is slow, the water flow does not impact the small particles directly on the surface of the screen 6, and the small particles can directly discharge the solid mixture from the sand outlet 71 when the valve 8 is opened during cleaning.
As in fig. 1 and fig. 2, the utility model discloses in the implementation, on the tiny particle that lets float in grit chamber 7 the superiors can not drop filter screen 6 for utilizing gravity, can also be to the left side slope of collector pipe 3 the upper end of filter screen 6, the below of tiny particle after the slope just is grit chamber 7 like this, filter screen 6's effect only plays the separation effect, can't let the tiny particle fall on filter screen 6, the diameter of deuterogamying leading water pipe 5 is less than collector pipe 3, let the water velocity after filtering relatively slow, water after the filtration does not have enough big kinetic energy to impact on filter screen 6 with tiny particle silt.
The utility model discloses a more specific embodiment is as shown in figure 1: the lower end of the filter screen 6 is connected to the seam 31 on the right side of the three-way structure.
In order to collect a water sample conveniently, a water stopping clip 91 is arranged on the water guide pipe 9, and the water stopping clip 91 has the following functions: on one hand, the water collecting bottle 92 is convenient to take down when the water collecting bottle 92 is full; the other function is that the water-stopping clip 91 can limit the speed of the water sample flowing into the water collecting bottle 92, and the water-stopping clip 91 can limit the water flow speed, which is generally used when the grit chamber 7 is full. Because the fuller silt will allow more small particles to float near the screen 6 and not settle to the bottom of the grit chamber 7.
When the water collecting nozzle 2 is used for collecting seepage water, in order to enable the arc surface of the seepage water wall 1 to be tightly attached to the collecting plate 21, the transverse collecting plate 21 is arranged at the lower part of the large-diameter end of the water collecting nozzle 2, and the collecting plate 21 with the arc surface structure can be better attached to the plane of the seepage water wall 1.
