Embodiment Construction

[0030] A new type of mechanical coal mine water tank water depth and water level measuring device such as figure 1 , consists of photoelectric encoder 1, housing 2, left coupling 3, left bearing support 4, steel wire rope 5, drum 6, right bearing support 7, right coupling 8, drum motor 9 to form a drum lifting device.

[0031] The clamping device is composed of a screw 10, a clamping motor 11, a polished rod 12 and a clamping baffle 13.

[0032] Such as figure 2 , the drum motor 9 is connected to the drum 6 through the right coupling 8, and the drum 6 is wound with a steel wire rope 5, and the drum motor 9 rotates to drive the drum 6 to rotate, so as to realize the action of retracting the wire rope 5, and finally the weight 14 is lifted; at the same time, the drum 6 The shaft is connected with the photoelectric encoder 1 through the left shaft coupling 3, and the rotation angle of the drum 6 is detected in real time by the photoelectric encoder 1.

Abstract

The invention belongs to the field of coal mine automatic detection, and discloses a method and a device for measuring water depth, water level and coal slime thickness of a coal mine water tank. The traditional method of measuring the depth of coal mine water tanks mainly relies on ultrasonic detection. Because the water at the junction of the mud-water interface is very turbid, the effect is poor. The measurement method of the present invention collects the rotation pulse signal of the photoelectric encoder in real time through the programmable controller, thereby measuring and calculating the real-time data such as the descending displacement, speed, acceleration and acceleration difference of the weight under the drum, and judging the water surface of the water tank The two critical points of the mud-water interface with the water tank, so as to calculate the falling distance of the weight, and finally obtain the water depth, water level and slime thickness of the coal mine water tank. The measuring device of the present invention consists of three parts: a roller lifting device, a clamping device and a control device. The invention is a mechanical detection sensor with strong anti-pollution ability, and realizes the simultaneous detection of water depth, water level and thickness of coal slime in a water tank.

Description

technical field [0001] The invention belongs to the field of coal mine automatic detection, and relates to a method and a device for measuring water depth, water level and coal slime thickness of a coal mine water tank. Background technique [0002] The traditional method of measuring water depth and water level in coal mine water tanks mainly relies on ultrasonic detection. Because the water at the junction of the mud-water interface in coal mine water tanks is very turbid, the measurement results are poor and it is easy to misjudge. At present, there is no sensor that can reliably Realize simultaneous detection of water level, water depth and slime thickness in coal mine water tank. [0003] Aiming at the problem of digital monitoring and control of the existing coal mine water tank, the present invention designs a safe, stable and reliable mechanical coal mine water tank water depth, water level and slime thickness detection sensor, which realizes the coal mine water tank...
