Description

Technical Field

[0001] The present application relates to the field of geological disaster technology, and specifically to a geological disaster early warning device. Background Art

[0002] A geological disaster early warning device is a device or system used to monitor, detect and warn of geological disasters. Its main function is to warn and predict potential geological disaster risks by real-time monitoring of changes in the geological environment, so as to detect and prevent possible geological disasters in advance, thereby reducing disaster losses and protecting people's lives and property.

[0003] When a mine accident occurs, groundwater around the mine will flow into the mine, causing a sudden drop in the groundwater level. Therefore, the sudden change in the groundwater level is related to the safe operation of the mine. It is necessary to monitor the changes in the groundwater level in real time through a groundwater level monitoring system to warn of abnormal groundwater levels that may cause mine collapse. However, most of the current measurements and records of groundwater levels are still done manually, making it difficult to quickly provide real-time graded warnings for changes in groundwater levels. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology and to propose a geological disaster early warning device to solve the problems existing in the prior art.

[0005] In order to achieve the above objectives, the utility model provides a geological disaster warning device, including a device frame, the top of the device frame is fixedly connected to a bracket, the inner surface of the bracket is rotatably connected to a winding roller, the outer surface of the winding roller is wound with a cable, the bottom of the cable is provided with a float cover, the device frame is provided with a guide mechanism for guiding the cable to pass, and the device frame is provided with a graded warning mechanism for constantly monitoring changes in groundwater levels.

[0006] Preferably, the guiding mechanism comprises a tube fixedly installed on the inner side of the device frame, and a guide wheel is fixedly installed on the top of the tube. The downward movement trajectory of the cable can be relatively limited by the guiding mechanism, so that it can move downward smoothly along the fixed trajectory, while also reducing the damage caused when passing through the tube.

[0007] Preferably, the line gathering mechanism includes a line gathering roller fixedly connected to the bottom of the device frame, and a line groove is provided on the outer surface of the line gathering roller. The cable can be wrapped around the line gathering roller for several turns through the line gathering mechanism to provide a certain space for normal water level changes.

[0008] Preferably, the graded warning mechanism includes a warning electrical box fixedly mounted on a device frame, the top wires of the warning electrical box are connected to a buzzer alarm light, and the graded warning mechanism can directly convert the change in water level into the change in the alarm sound of the buzzer alarm light.

[0009] Preferably, a sliding rheostat is provided inside the early warning electrical box, and a sliding shaft is provided on the sliding rheostat.

[0010] Preferably, a lightweight connecting frame is slidably connected to the outer surface of the sliding shaft, the bottom of the lightweight connecting frame is fixedly connected to the cable, and a sliding variable resistance piece is arranged at the end of the lightweight connecting frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The geological disaster early warning device can convert the change of groundwater level into the change of alarm sound of buzzer alarm light through the graded early warning mechanism. The louder the alarm sound, the more rapid the change of groundwater level is. Different degrees of real-time alarm monitoring can be carried out on outsiders to accurately understand the trend and speed of water level changes, improve the timeliness and accuracy of early warning, and take countermeasures more timely.

[0013] 2. For this geological disaster early warning device, when the groundwater level drops slightly within the normal range, the float cover will continue to be lowered by pulling the cable under the action of gravity until the float cover floats on the groundwater surface after the water level changes. During this process, the cable will gradually detach from the wire groove on the surface of the wire gathering roller and will not trigger the graded early warning mechanism.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4 A geological disaster early warning device includes a device frame 1, a bracket 4 is fixedly connected to the top of the device frame 1, a winding roller 5 is rotatably connected to the inner surface of the bracket 4, a cable 6 is wound around the outer surface of the winding roller 5, a floating cover 7 is arranged at the bottom of the cable 6, a guide mechanism for guiding the cable 6 to pass is arranged on the device frame 1, a line gathering mechanism is arranged on the device frame 1, and a graded early warning mechanism for constantly monitoring the changes in the groundwater level is arranged on the device frame 1.

[0021] Through the above technical solution, when the device is in use, the cable 6 is first lowered through the winding roller 5 until the float cover 7 is on the water surface of the groundwater level. It will float up under the action of buoyancy, and the line gathering mechanism can provide a normal water level change space. During this process, the graded warning mechanism will not be triggered, but the graded warning mechanism will be triggered when the groundwater level drops sharply.

[0022] Specifically, the guide mechanism includes a tube 2 fixedly inserted into the inner side of the device frame 1 , and a guide wheel 3 is fixedly installed on the top of the tube 2 .

[0023] Through the above technical solution, the left and right sets of guide wheels 3 can allow the cable 6 to be lowered along the corresponding trajectory, reducing the wear caused when passing through the tube 2.

[0024] Specifically, the wire gathering mechanism includes a wire gathering roller 8 fixedly connected to the bottom of the device frame 1, and a wire groove 9 is formed on the outer surface of the wire gathering roller 8.

[0025] Through the above technical solution, when the buoy cover 7 floats on the groundwater surface, the cable 6 can be wound in the wire groove 9 on the wire gathering roller 8. During this process, the cable 6 in the wire groove 9 will basically not be affected by the gravity of the floating buoy cover 7, and thus will basically remain in a wound state on the wire gathering roller 8.

[0026] Specifically, the graded warning mechanism includes a warning electric box 10 fixedly mounted on the device frame 1 , and a buzzer alarm light 11 is connected to the top wire of the warning electric box 10 .

[0027] Through the above technical solution, the buzzer alarm light 11 will gradually emit an alarm sound with higher and higher decibels as the supply current increases.

[0028] Specifically, a sliding rheostat 12 is disposed inside the early warning electrical box 10 , and a sliding shaft 13 is disposed on the sliding rheostat 12 .

[0029] Through the above technical solution, when the sliding rheostat 15 slides up and down along the sliding rheostat 12, the resistance of the sliding rheostat 12 connected to the circuit can be changed.

[0030] Specifically, a lightweight connecting frame 14 is slidably connected to the outer surface of the sliding shaft 13 , the bottom of the lightweight connecting frame 14 is fixedly connected to the cable 6 , and a sliding variable resistance sheet 15 is provided at the end of the lightweight connecting frame 14 .

[0031] Through the above technical solution, the sliding rheostat 15 can slide on the sliding rheostat 12, and the two are electrically connected, and the lightweight connecting frame 14 is also electrically connected to the early warning electrical box 10.

[0032] Working principle: When the device is in use, first rotate the winding roller 5 to let the cable 6 pass through the tube 2 and be lowered until the buoy cover 7 floats on the groundwater surface. At this time, the cable 6 can continue to be lowered for a certain distance, and the cable 6 is wound around the line groove 9 opened on the surface of the line gathering roller 8. When the groundwater level drops slightly within the normal range, the buoy cover 7 will pull the cable 6 to continue to be lowered under the action of gravity until the buoy cover 7 floats on the groundwater surface after the water level changes. During this process, the cable 6 will gradually break away from the line groove 9 on the surface of the line gathering roller 8. When the groundwater level changes dramatically, it is very likely that a mine accident has occurred. The groundwater around the mine will flow into the mine, causing a sudden drop in the groundwater level. During this process, all the cables 6 wound on the line gathering roller 8 are detached from it and will continue to be lowered. At this time, during the lowering process, the cables 6 will drive the lightweight connecting frame 14 to move downward synchronously, so that the lightweight connecting frame 14 slides down along the sliding shaft 13, and the sliding rheostat 15 slides down along the sliding rheostat 12, so that the resistance of the sliding rheostat 12 connected to the circuit is reduced, and the current increases accordingly. At this time, the buzzer alarm light 11 gradually emits more and more piercing alarms, thereby conducting different degrees of real-time alarm monitoring on outside personnel in a hierarchical manner, accurately understanding the changing trend and speed of the water level, improving the timeliness and accuracy of the early warning, and being able to take countermeasures more promptly, thereby ensuring the safety of the staff to the greatest extent.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
