The mine tailing pond flood drainage and water return system is of a well-hole type structure, namely a drainage vertical shaft with a hole opening is built in a water area at the tail of a mine tailing pond area, the vertical shaft is connected with a drainage pressure tunnel, the pressure of the pressure tunnel is prevented from being too large, the damage of a tunnel outlet is caused, a pressure reduction vertical shaft needs to be built near the pressure tunnel outlet to reduce the pressure in the tunnel, the pressure reduction vertical shaft is generally high and is more than dozens of meters, and the water level change in the pressure reduction vertical shaft needs to be monitored at any time in order to know the pressure change and the flow condition in the tunnel, so the water level in the vertical shaft needs to be measured frequently.
The current methods for measuring the water level in the shaft well commonly used are as follows:
firstly, adopt the level gauge to measure the water level elevation in the shaft, although this kind of method precision is high, can monitor the water level change in the shaft at any time, nevertheless because the tailing storehouse is located remote area more, the installation level gauge need lay longer communication line, invests in greatly, the maintenance cost is high.
Secondly, adopt well water level electricity survey rope to measure, climb to the decompression shaft top through the people, slowly put down probe end survey rope to the well, when the probe touches water, the pointer table can swing or the light, stop putting down the survey rope at this moment, look over the scale label of well head department survey rope and be well water level, although this kind of method measurement accuracy is high, the cost is lower, nevertheless has following several kinds of shortcomings: the danger coefficient is large, people need to climb to the top of the high tower for measurement, and great potential safety hazards exist; the operation is inconvenient, and the water level change condition in the tower cannot be observed at any time.
Disclosure of Invention
The utility model aims at providing a low, the long service life of investment cost, measurement accuracy height, convenient and fast's a device for tailing storehouse decompression shaft water level measurement.
The purpose of the utility model is realized by the following technical scheme:

Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the bracket of the present invention.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the utility model discloses a device for tailing storehouse decompression shaft water level measurement, its characterized in that sets up two pulleys 7 on this support 3 including setting up the support 3 at decompression shaft well head, twines steel cable 4 on these two pulleys 7, sets up the ball end and the weight end of floating that set up respectively at this steel cable 4 both ends, along the vertical scale 1 that sets up of decompression shaft wall of a well, the ball end include two floaters 5 and a weight 6, the weight end include an iron ball 2.
The weight of the floating ball end is greater than that of the weight end, and the difference between the weights of the floating ball end and the weight end is less than the buoyancy of the two floating balls 5.
Two holes are arranged on the bracket 3, the floating ball end of the steel rope 4 passes through one hole and hangs down into the decompression shaft, and the heavy hammer end of the steel rope 4 passes through the other hole and hangs down beside the scale 1.
The utility model discloses a device for tailing storehouse decompression shaft water level measurement, including removing floater 5, heavy object 6, pulley 7, weight iron ball 2, steel cable 4, support 3, scale 1. Firstly, a support 3 is manufactured according to the diameter size of a wellhead of the pressure reduction shaft, 20# channel steel is generally adopted as a material, and two holes are formed in the support 3 and are used as passing holes for steel ropes 4 at a floating ball end and a heavy hammer end. A pulley 7 is respectively arranged at two openings of the bracket 3 to support the steel rope 4 to pass and slide;
manufacturing a 'floating ball-heavy hammer' device, which is divided into a floating ball end and a heavy hammer end, wherein the floating ball end consists of two floating balls 5 and a heavy object 6, the heavy hammer end consists of an iron ball 2, the floating ball end and the heavy hammer end are connected by a steel rope 4, the weight of the floating ball end is slightly larger than that of the heavy hammer end, and the difference between the weights of the floating ball end and the heavy hammer end is smaller than the buoyancy of the floating ball 5; the floating ball 5 can be made of stainless steel or plastic;
the device can be installed after being manufactured, firstly, the bracket 3 is installed at the top end of the pressure reducing vertical shaft by a crane and is firmly welded with an embedded part of the pressure reducing vertical shaft, then a floating ball-heavy hammer device is installed, the water level in the vertical shaft at the moment is measured by a well water level electric measuring rope, the position of the heavy hammer at the moment is marked, and the marking is sequentially carried out up and down at intervals of a measuring unit according to the mark.
The principle is as follows: because the weight of the floating ball end is greater than that of the counterweight end, and the weight difference between the floating ball end and the counterweight end is less than the buoyancy of the floating ball, the floating ball 5 can keep balance on the water surface, and the scale of the position of the iron ball 2 of the counterweight is the actual water level value in the well.
The utility model discloses a device for tailing storehouse decompression shaft water level measurement is a device that is used for water level measurement in all kinds of shafts such as tailing storehouse decompression shaft, through install "floater-weight" device on the shaft, and draw scale 1 on the shaft, pass through pulley 7 with steel cable 4 and be connected floater 5 and weight iron ball 2, utilize water to floater 5's buoyancy, when water level variation, observe 2 place scale intervals of weight iron ball and can accurately measure the shaft water level value, the device investment cost is low, long service life, measurement accuracy is high, convenient and fast.
