Description

Technical Field

[0001] The utility model relates to the technical field of hydrological measurement, in particular to a mine hydrological measurement device. Background Art

[0002] Measuring the amount of water inflow in a mine is an important part of mine hydrological survey. The amount of water inflow has a very important impact on the selection of mine construction plans and water prevention and control measures, the length of the mine construction period and its economic benefits. Accurately measuring the amount of water inflow in a mine can provide a reliable hydrogeological basis for formulating a safe and reasonable construction plan, thereby speeding up mine construction and saving infrastructure investment.

[0003] Prior art, for example, a utility model is a device for measuring water inflow in a mine based on the buoy method, with the authorization announcement number CN219327562U. By threading a spiral lifting cover on the buoy, the height between the spiral lifting cover and the buoy can be adjusted according to different water flow rates, so that the first photoelectric sensor and the second photoelectric sensor can detect the movement of the buoy, so that the device can be used to measure mines with different water inflows.

[0004] At present, there is still a lack of a device that measures the flow rate by using an ultrasonic flow meter and indirectly measures the water depth through a distance sensor to achieve flow rate and flow monitoring, while ensuring that the distance measuring frame moves smoothly along the U-shaped frame to ensure the measurement of the distance measuring sensor.

[0005] Therefore, in view of the above problems, a mine hydrological measurement device is proposed to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model develops a mine hydrological measuring device, which measures the flow velocity by adopting an ultrasonic flow meter and indirectly measures the water depth by a distance measuring sensor, thereby realizing flow velocity and flow rate monitoring, and at the same time ensures that the distance measuring frame moves smoothly along the U-shaped frame to ensure the distance measuring sensor measurement.

[0007] The technical solution of the utility model to solve the technical problem is as follows: the utility model provides a mine hydrological measurement device, including: a drainage ditch, the drainage ditch is connected to a bracket, the drainage ditch is connected to a U-shaped frame; an ultrasonic flow meter is connected to the bracket; a distance sensor is connected to the horizontal plate of the U-shaped frame; a distance frame, the two vertical rods of the U-shaped frame pass through the distance frame respectively, the distance frame is connected to symmetrical vertical plates, and the symmetrical vertical plates are respectively connected to buoyancy blocks; a controller is connected to the bracket, and the ultrasonic flow meter and the distance sensor are respectively electrically connected to the controller. The flow velocity is measured by using an ultrasonic flow meter, and the water depth is indirectly measured by a distance sensor, so as to realize flow velocity and flow monitoring.

[0008] As an optimization, the distance measuring frame is connected to the vertical axis, the vertical axis bearing is connected to symmetrical round tubes, and the symmetrical round tubes are respectively connected to protective plates. By adopting a reciprocating protective plate, floating objects are prevented from contacting the U-shaped frame, ensuring that the distance measuring frame moves smoothly along the U-shaped frame when the water level changes.

[0009] As an optimization, the symmetrical vertical plates are respectively connected to the horizontal plates, the symmetrical horizontal plates are respectively connected to the central axis of the turntable by bearings, the symmetrical eccentric parts of the turntable are respectively connected to the L-shaped rods, and the symmetrical L-shaped rods are respectively connected to the corresponding protective plates. By using the turntable, the protective plates can swing back and forth when the turntable rotates.

[0010] As an optimization, the symmetrical vertical plates are respectively connected to the central axis of the water wheel by bearings, the two ends of the central axis of the water wheel are respectively connected to the driving bevel gears, the central axes of the symmetrical turntables are respectively connected to the driven bevel gears, and the symmetrical driving bevel gears are respectively meshed with the corresponding driven bevel gears. By meshing the water wheel and the bevel gears and using the water flow to drive, the swing of the protective plate is realized, which is convenient to use.

[0011] As an optimization, the material of the buoyancy block includes wood, plastic, rubber and foam and its surface is smooth. By utilizing its buoyancy, the driven bevel gear is slightly above the water surface, and the rangefinder etc. float on the water surface.

[0012] As an optimization, the surface of the protective plate is smooth, so that debris can be discharged to both sides after contacting the protective plate, avoiding contact with the U-shaped frame.

[0013] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0014] (1) This device measures flow velocity by using an ultrasonic flow meter and indirectly measures water depth through a distance sensor to achieve flow rate and flow monitoring.

[0015] (2) This device uses a reciprocating protective plate to prevent floating objects from contacting the U-shaped frame, ensuring that the ranging frame moves smoothly along the U-shaped frame.

[0025] like Figures 1 to 5 As shown, embodiment 1: a mine hydrological measurement device, comprising: a drainage ditch 1, the drainage ditch 1 is connected to a bracket 2, the drainage ditch 1 is connected to a U-shaped frame 5; an ultrasonic flow meter 3, connected to the bracket 2; a distance sensor 6, connected to the horizontal plate of the U-shaped frame 5; a distance frame 7, two vertical rods of the U-shaped frame 5 respectively pass through the distance frame 7, the distance frame 7 is connected to symmetrical vertical plates 17, and the symmetrical vertical plates 17 are respectively connected to buoyancy blocks 11; a controller 4, connected to the bracket 2, the ultrasonic flow meter 3 and the distance sensor 6 are respectively electrically connected to the controller 4. By using the ultrasonic flow meter 3 to measure the flow velocity, the water depth is indirectly measured by the distance sensor 6, and the flow rate and flow rate monitoring is realized.

[0026] The ultrasonic flowmeter 3 adopts the non-contact measurement principle, which does not require direct contact with the fluid, avoids contamination and resistance, and ensures the accuracy and stability of the measurement. Its measurement accuracy is high. With the help of advanced ultrasonic technology, the ultrasonic flowmeter has high-precision flow measurement capabilities and can meet the strict requirements of industrial production for flow measurement accuracy. For example, the flow measurement range of some ultrasonic Doppler flowmeters can reach 0.02~7.00m / s, and the measurement accuracy is ±1.0%±cm / s.

[0027] The model of the controller 4 is STM32F103VCT6.

[0028] The model of the distance measuring sensor 6 is BL-30NZ.

[0029] The workflow of this embodiment is:

[0030] The ultrasonic flowmeter 3 measures the water flow velocity, and the distance sensor 6 measures the distance between it and the distance frame 7. Using the distance between the distance sensor 6 and the bottom surface of the drain ditch 1 and the distance between the distance frame 7 and the liquid level, the controller 4 calculates the liquid level height, and uses the width of the drain ditch 1 to calculate the real-time cross-section of the water flow, which is multiplied by the flow velocity to obtain the flow rate.

[0031] Embodiment 2: This embodiment is further described on the basis of embodiment 1, wherein the distance measuring frame 7 is connected to the vertical shaft 10, the vertical shaft 10 is connected to the symmetrical circular tubes 18 by bearings, and the symmetrical circular tubes 18 are respectively connected to the protective plates 8. By adopting the reciprocating protective plates 8, floating objects are prevented from contacting the U-shaped frame 5, ensuring that the distance measuring frame 7 moves smoothly along the U-shaped frame 5 when the water level changes.

[0032] The symmetrical vertical plates 17 are respectively connected to the horizontal plates 16, the symmetrical horizontal plates 16 are respectively bearing-connected to the central axis of the turntable 12, the symmetrical eccentric parts of the turntable 12 are respectively rotationally connected to the L-shaped rods 9, and the symmetrical L-shaped rods 9 are respectively rotationally connected to the corresponding protective plates 8. By adopting the turntable 12, when the turntable 12 rotates, the reciprocating swing of the protective plates 8 is achieved.

[0033] The symmetrical vertical plates 17 are respectively connected to the central axis of the water wheel 13 by bearings, and the two ends of the central axis of the water wheel 13 are respectively connected to the driving bevel gear 14, and the central axis of the symmetrical turntable 12 is respectively connected to the driven bevel gear 15, and the symmetrical driving bevel gears 14 are respectively meshed with the corresponding driven bevel gears 15. By adopting the meshing of the water wheel 13 and the bevel gears and driving by the water flow, the swing of the protective plate 8 is realized, which is convenient to use.

[0034] The material of the buoyancy block 11 includes wood, plastic, rubber and foam and its surface is smooth. Utilize its buoyancy to realize that the driven bevel gear 15 is slightly above the water surface, and the rangefinder 7 etc. float on the water surface.

[0035] The surface of the protective plate 8 is smooth, so that the debris can be discharged to both sides after contacting the protective plate 8, and avoid contacting the U-shaped frame 5.

[0036] The workflow of this embodiment is:

[0037] When water flows, it drives the water wheel 13 to rotate, the water wheel 13 drives the active bevel gear 14 to rotate, the active bevel gear 14 drives the driven bevel gear 15 and the turntable 12 to rotate, the turntable 12 drives the L-shaped rod 9 to swing, the L-shaped rod 9 drives the protective plate 8 to swing, and the protective plate 8 drives the round tube 18 to rotate.

[0038] As the water level changes, under the action of buoyancy, the buoyancy block 11 moves, the buoyancy block 11 drives the vertical plate 17 to move, the vertical plate 17 drives the distance measuring frame 7 to move along the U-shaped frame 5, the vertical plate 17 and the distance measuring frame 7 drive the horizontal plate 16, the water wheel 13, the active bevel gear 14, the driven bevel gear 15, the turntable 12, the L-shaped rod 9, the vertical shaft 10, the round tube 18 and the protective plate 8 to move.

[0039] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
