Description

Technical Field

[0001] This utility model relates to the field of downhole monitoring equipment, and in particular to a downhole water inrush monitoring device. Background Technology

[0002] The hazard of underground water inrush is a key concern in coal mine safety management. Water inrush can damage equipment and, in severe cases, destroy roadways and support structures. Due to the presence of aquifers, water inrush is often unavoidable during mining due to the combined risks of geological structures, precipitation, natural disasters, and the influence of adjacent mines. Therefore, timely detection of water inrush is crucial.

[0003] Existing water inrush monitoring equipment has certain drawbacks. First, the selection of sensors is unreasonable. Water immersion sensors or water level sensors are commonly used. Water immersion sensors are often affected by the humid environment underground and will often cause false alarms. Water level sensors are affected by deformation due to the location of the roadway, goaf, etc., or the sensor placement location, resulting in inaccurate water level detection. This can lead to sensor damage or untimely alarms. There is currently no corresponding solution to this problem. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a downhole water inrush monitoring device that is simple in structure, less affected by the placement environment, and safer to use.

[0005] The equipment includes a support frame, a trigger float mechanism, sensors, and an alarm unit;

[0006] The aforementioned support frame is the assembly basis of this equipment and also the basis for the stable placement of the equipment at the water inrush monitoring position;

[0007] A trigger float mechanism is movably mounted on the bracket. The trigger float includes a float at the bottom, a guide rod integrally mounted on the float, and a trigger block at the end of the guide rod.

[0008] A sensor is installed on the upper part of the bracket, and the sensor is positioned to correspond to the position of the trigger block and the floating stroke setting.

[0009] The sensor signal is connected to the alarm unit.

[0010] The effect achieved is that when water surge occurs, the float rises, causing the trigger block to rise to the sensor's sensing area. The sensor then sends a signal to the alarm unit, which then sounds an alarm.

[0011] The beneficial effects of this utility model are: it solves many problems existing in the current downhole water inflow monitoring equipment, and achieves water inflow monitoring with a simple structure and low cost, which is unaffected by humidity and highly resistant to geological changes. In particular, the trigger stroke of the equipment is adjustable, and its application range is also wider. Attached Figure Description

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 , Figure 2 The present invention provides a downhole water inrush monitoring device, which includes a support, a trigger float mechanism, a sensor 2, and an alarm unit 1.

[0018] The aforementioned support frame is the assembly basis of this equipment and also the basis for the stable placement of the equipment at the water inrush monitoring position;

[0019] A trigger float mechanism is movably mounted on the bracket. The trigger float 7 includes a float at the bottom, a guide rod 6 integrally mounted on the float 7, and a trigger block 5 at the end of the guide rod 6.

[0020] The upper part of the bracket is provided with a sensor 2, and the position of the sensor 2 corresponds to the position of the trigger block 5 and the floating stroke setting;

[0021] The sensor 2 is connected to the alarm unit 1.

[0022] The effect achieved is that when water surge occurs, the float 7 rises, causing the trigger block 5 to rise to the sensing area of ​​the sensor 2. The sensor 2 then sends a signal to the alarm unit 1, which then triggers an alarm.

[0023] Example 1, refer to the accompanying drawings in the specification. Figure 1 The bracket includes a base frame and an adjustable bracket;

[0024] The base frame includes a base plate 8, and the base plate 8 is provided with inclined support columns 9, and at least one column is provided with a rooting hole;

[0025] The effect achieved is that the rooting hole is used for the overall rooting of the equipment; and based on the fact that the equipment is rooted, it is beneficial for the equipment to cope with changes in the geological environment. The upward stroke of its float 7 is always the trigger basis, avoiding equipment damage and false triggering.

[0026] The adjustable bracket is located on the upper part of the base frame and includes a connecting rod 4 integrally mounted on the base plate 8. A support plate 3 is also fixedly mounted on the connecting rod 4. The sensor 2 and the alarm unit 1 are mounted on the support plate 3.

[0027] The effect achieved in this way is to optimize the assembly structure.

[0028] Furthermore, the connecting rod 4 is a tube-sleeve structure, including an inner sleeve and an outer sleeve, and a positioning pin is also provided on the outer sleeve.

[0029] This achieves the effect of raising or lowering the height of sensor 2, which corresponds to the alarm stroke of float 7.

[0030] In Example 2, an assembly hole is provided in the center of the base plate 8, and the guide rod 6 is installed inside the assembly hole.

[0031] The effect achieved is to constrain the guide rod's stroke by 6.

[0032] Furthermore, the inner surface of the assembly hole is provided with ball bearings.

[0033] This achieves the effect of facilitating a smooth ascent of the float 7.

[0034] In Example 3, the sensor 2 is an inductive proximity sensor; the trigger block 5 is a metal sheet.

[0035] This is achieved because inductive proximity sensors are less affected by humidity, making them more suitable for damp underground environments and preventing sensor 2 from being falsely triggered.

[0036] Example 4: The alarm unit 1 integrates a battery, a wireless signal transmission module, and an audible and visual alarm device.

[0037] Preferably, the wireless signal transmitting module is connected to the ground unit.

[0038] This achieves the effect that both the site and the ground can receive the alarm signal immediately.

[0039] In Example 5, the tray 3 is provided with a centrally located mounting hole, and the sensor 2 is fixed in the mounting hole by a double threaded sleeve.

[0040] This facilitates the assembly of sensor 2 and enables precise adjustment of its position.
