Description

Underground water burst monitoring device Technical Field The utility model relates to the field of underground monitoring equipment, in particular to an underground water burst monitoring device. Background Underground water burst hazard is a key work which needs to be focused on in coal mine production security work. The water burst can cause equipment damage, and the tunnel and supporting equipment are destroyed when serious. Because of the existence of the aquifer, water gushing conditions cannot be avoided due to superposition of risks such as geological structures, precipitation, natural disasters, influence of adjacent mines and the like in the exploitation process, and the method is particularly important for timely finding the water gushing conditions. The water burst monitoring equipment in the prior art has certain drawbacks, firstly, the selection of the sensor is unreasonable, a water logging sensor or a water level sensor is commonly used, wherein the water logging sensor is influenced by underground humid environment and frequently has false alarm conditions, the water level sensor has deformation influences due to positions such as a roadway and a goaf, or the arrangement position of the sensor has deformation influences, the water level detection caused is inaccurate, the sensor is damaged or the alarm is not timely, and corresponding solving equipment is still lacked at present for the problem. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the underground water inflow monitoring device which is simple in structure, less influenced by arrangement environment and safer to use. The device comprises a bracket, a triggering floating ball mechanism, a sensor and an alarm unit; The support is an assembly foundation of the equipment and is also an arrangement foundation of the equipment stably configured at a water burst monitoring position; The support is movably provided with a triggering floating ball mechanism, and the triggering floating ball comprises a floating ball arranged at the bottom, a guide rod integrally arranged on the floating ball and a triggering block at the end of the guide rod; The upper part of the bracket is provided with a sensor, and the setting position of the sensor corresponds to the position of the trigger block and the floating travel; The sensor signal is connected with the alarm unit. The effect of realizing with this is, gushes water the condition and appears the back, and the floater rises and drives the trigger piece and rise to sensor sensing area, and the sensor reports to the alarm unit, and alarm unit reports to the police. The underground water gushing monitoring device has the beneficial effects that the underground water gushing monitoring device solves a plurality of problems existing in underground water gushing monitoring devices in the prior art, and realizes water gushing monitoring with high resistance to geological change without being influenced by humidity with a simple structure and low manufacturing cost. In particular, the trigger stroke of the device is adjustable, and the application range is wider. Drawings FIG. 1 is a schematic diagram of a downhole water burst monitoring device according to the present utility model; FIG. 2 is a schematic view of an assembly structure of the underground water gushing monitoring device according to the present utility model based on FIG. 1; Reference numerals: 1-alarm unit 2-sensor 3-supporting plate 4-connecting rod 5-trigger block 6-guide rod 7-floating ball 8-bottom plate 9-supporting column base The achievement of the objects, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings, in conjunction with the embodiments. Detailed Description Referring to fig. 1 and 2, the underground water burst monitoring device comprises a bracket, a trigger floating ball mechanism, a sensor 2 and an alarm unit 1; The support is an assembly foundation of the equipment and is also an arrangement foundation of the equipment stably configured at a water burst monitoring position; the support is movably provided with a triggering floating ball mechanism, and the triggering floating ball 7 comprises a floating ball arranged at the bottom, a guide rod 6 integrally arranged on the floating ball 7 and a triggering block 5 at the end of the guide rod 6; The upper part of the bracket is provided with a sensor 2, and the setting position of the sensor 2 corresponds to the position of the trigger block 5 and the floating travel; The sensor 2 is in signal connection with the alarm unit 1.
