Description

Technical Field

[0001] This utility model relates to the field of mine water technology, specifically a water inrush point flow monitoring device. Background Technology

[0002] By measuring parameters such as water inflow and water level in real time, abnormal water level changes can be quickly detected, and the risk of water inrush can be warned in a timely manner. By analyzing the correlation between water inflow and mining progress, the selection of mining areas can be optimized, and operations in high water level areas can be avoided.

[0003] Chinese patent CN221099793U discloses a Doppler flow meter, including a detection probe, a data transmission line, a flow meter body, and a convenient component. The convenient component includes a connecting plate, an extension rod, a connecting rod, a suction cup, a cylinder, a motor, a limiting component, a hexagonal transmission rod, a support rod, a support base, and a support frame. In using this invention, the data transmission line is inserted into the detection probe and the flow meter body. The detection probe is attached to the connecting plate by the suction cup, and the flow meter body is clamped onto the support frame. The cylinder drives the extension rod to extend from the connecting rod, thus extending the detection range. The other side of the connecting rod is mounted on the support rod via the hexagonal transmission rod. The output end of the motor drives the hexagonal transmission rod to rotate and adjust the height of the detection probe, changing the detection position to ensure that the flow velocity at different locations can be fully detected.

[0004] The above solution can detect flow velocity at different locations, but when adjusting the detection probe, the communication cable may become loose. Loose communication cable can lead to unstable signal transmission. In harsh environments, the communication cable may sway with the wind, which may cause intermittent transmission interruption or data abnormality, thus affecting the accuracy of flow monitoring at the water inrush point. Utility Model Content

[0005] The purpose of this invention is to provide a water inrush point flow monitoring device to solve the problem mentioned in the background art that communication cables may sway with the wind, potentially causing intermittent transmission interruptions or data anomalies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow monitoring device for a water inrush point, comprising a U-shaped bracket, an adjustable height assembly on the top of the U-shaped bracket, a display fixedly mounted on the top of the adjustable height assembly, a communication cable fixedly mounted on one side of the display, a flow meter probe fixedly mounted on one end of the communication cable, the flow meter probe being fixedly connected to the U-shaped bracket, a tensioning assembly on one side of the adjustable height assembly, a limit assembly on the top of the tensioning assembly, and a direction pointer movably connected to the outer end of the adjustable height assembly;

[0007] Preferably, the tensioning assembly includes a fixed plate, which is fixedly installed on one side of the adjusting assembly. A winding reel is drivenly connected to one side of the fixed plate, and a rotating handle is fixedly installed on one side of the winding reel.

[0008] Preferably, the limiting component includes a guide rod, which is fixedly installed on one side of the fixed plate. An adjusting plate is slidably connected to the outer end of the guide rod, and a spring is sleeved on the outer end of the guide rod. An insertion rod is fixedly installed on one side of the adjusting plate, and a plurality of insertion slots are provided through one side of the winding reel.

[0009] Preferably, the height adjustment component includes a storage rod, which is fixedly installed on the top of the U-shaped bracket. A T-shaped threaded tube is fixedly installed on the top of the storage rod, and the top of the T-shaped threaded tube has multiple adjustment slots.

[0010] Preferably, the outer end of the T-shaped threaded tube is threadedly connected to a T-shaped threaded sleeve, and an adjusting probe passes through the interior of the T-shaped threaded sleeve. One side of the adjusting probe is fixedly connected to the display.

[0011] Preferably, the fixed plate is fixedly connected to the other side of the adjusting probe, and the communication cable passes through the fixed plate and is wound around the outer end of the winding reel.

[0012] Preferably, the two sides of the spring are fixedly connected to the fixed plate and the adjusting plate respectively, and the insertion rod is engaged with the insertion slot.

[0013] Preferably, the adjusting probe passes through the T-shaped threaded tube and is slidably connected to the inner wall of the receiving rod, and the T-shaped threaded sleeve is fitted on the outer end of the adjusting probe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a tensioning component and rotating the handle, the winding reel rotates, which can wind and tension the communication cable. When the communication cable is not in use, it can be wound up for easy carrying. At the same time, when adjusting the height of the equipment, the tension of the communication cable can also be adjusted to avoid signal attenuation or short circuits due to slack in the communication cable. Especially in harsh environments, stable tension helps to reduce the impact of external interference on transmission quality, making the flow monitoring of the water inrush point more accurate.

[0016] 2. By setting a limiting component, the insertion rod is locked inside the insertion slot, which can limit the winding reel and prevent it from rotating due to external factors. This prevents the communication cable from becoming loose during winding, thus making the winding of the communication cable more stable and improving the stability of the communication cable transmission.
