Description

Technical Field

[0001] This utility model relates to the field of coal mine detection, and in particular to a device for detecting water accumulation in coal mine goaf areas. Background Technology

[0002] After coal mine exploration and mining, the goaf areas left behind pose a significant risk. To avoid affecting surrounding mines, the water accumulation in the goaf areas must be monitored regularly to prevent goaf erosion and collapse. When conducting water accumulation detection, a transient electromagnetic instrument is required. To use the transient electromagnetic instrument, one end of the water accumulation detection cable with a plug is connected to the transient electromagnetic instrument, and the other end is deployed into the goaf area to be monitored, thus enabling the detection of water bodies in the coal mine goaf areas.

[0003] A search revealed a Chinese patent publication number CN220271575U that discloses a device for detecting water accumulation in coal mine goaf areas. This patent includes an electric rope winding and unwinding mechanism and a support platform that can be mounted on the electric rope winding and unwinding mechanism. The electric rope winding and unwinding mechanism includes a rotatable support bracket and a drum rotatably mounted between the support brackets. The drum has a cavity with one open end, and a slot communicating with the cavity is opened along its axial direction on the side wall of the drum. The water accumulation detection electric rope is wound around the outside of the drum. One end of the water accumulation detection electric rope with a plug extends into the cavity through the slot and can extend out of the cavity opening. The end of the water accumulation detection electric rope extending out of the cavity can be plugged into a transient electromagnetic instrument. When in use, the support frame of this device is deployed above the goaf. Rotating the drum allows the water detection rope wound on it to be lowered into the goaf more easily, making the deployment of the water detection rope more convenient. However, this device lacks a means of guiding the detection rope, which means that the detection rope needs to be manually guided during its entry into the goaf, resulting in low safety. Furthermore, existing coal mine goaf water detection devices may experience bending or jamming of the detection rope during its entry into the goaf due to the complex conditions inside the goaf, affecting the accuracy of the detection data.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6As shown, a coal mine goaf water accumulation detection device includes a movable frame 101. Several casters 102 are provided at the bottom of the movable frame 101. A push handle 103 is bolted to the movable frame 101. Several wire holes 104 are provided on one side of the movable frame 101, arranged in a ring with the mounting shaft 201 as the center. A placement platform 105 is bolted to one side of the movable frame 101, allowing the transient electromagnetic instrument to be fixed on the placement platform 105 for easy operation during water accumulation detection. An installation mechanism is provided on the movable frame 101, including a mounting shaft 201 bolted to the inside of the movable frame 101. A sliding groove 202 is provided on the mounting shaft 201, and a rotating sleeve 203 is slidably connected to the sliding groove 202. A winding seat 204 is rotatably connected to the rotating sleeve 203, and a through hole 205 is provided on one side of the winding seat 204. A drive mechanism is provided on the upper part, which includes a mounting ring 301 slidably connected to a mounting shaft 201. A mounting plate 302 is bolted to the mounting ring 301, and a power component 303 is bolted to the mounting plate 302. The power component 303 includes a dust cover and a motor. A transmission component is provided at the power output end of the power component 303. The output shaft of the motor extends out of the dust cover and is connected to the transmission component. The transmission component is used to drive the winding seat 204 to rotate. A guide mechanism is provided on the movable frame 101, which includes a fixed shaft 401. A guide seat 402 is movably mounted on the fixed shaft 401. A connecting component is provided between the guide seat 402 and the winding seat 204. A shaking mechanism is provided at the output end of the power component 303. The shaking mechanism is used to shake the detection rope. A locking mechanism is provided on the mounting plate 302. The locking mechanism is used to lock the position of the rotating sleeve 203.

[0027] In this embodiment, the transmission component includes a first gear 304, which is connected to the power output end of the power component 303 via a coupling. A second gear 305 meshes on the first gear 304, and the second gear 305 is bolted to one end of the winding seat 204. When the motor on the power component 303 starts, the first gear 304 and the second gear 305 drive the winding seat 204 to rotate, and the winding seat 204 can unwind the detection rope wound on it.

[0028] In this embodiment, the connecting assembly includes several collars 403, which are rotatably connected to one side of the guide seat 402, the second gear 305, and the first gear 304, respectively. The collars 403 are connected to the same connecting plate 404 by bolts. The connecting plate 404 enables the winding seat 204 to move synchronously with the power assembly 303 and the guide seat 402 when it moves along the axial direction of the mounting shaft 201, thereby adjusting the position of the detection rope on the moving frame 101. This allows the rope to accurately enter the goaf area of ​​the coal mine and perform multi-point detection, improving detection accuracy.

[0029] In this embodiment, a connecting seat 405 is bolted to the connecting plate 404, and a guide plate 406 is bolted to the connecting seat 405. After the detection rope is unwound from the winding seat 204, it passes through the connecting seat 405 and the guide seat 402 and enters the goaf area. The guide seat 402 and the connecting seat 405 play a good guiding role, and no manual guidance is required.

[0030] In this embodiment, the rocking mechanism includes an eccentric shaft 501, which is bolted to the power output end of the power assembly 303 and is eccentrically positioned. A rocker arm 502 is rotatably connected to the eccentric shaft 501. A connecting shaft 503 is rotatably connected to the end of the rocker arm 502 away from the eccentric shaft 501. A push rod 504 is bolted to the connecting shaft 503. A connecting rod 505 is slidably connected to the push rod 504. The connecting rod 505 is bolted to the bottom of the guide plate 406. A guide ring 506 is welded to the end of the push rod 504 away from the connecting shaft 503.

[0031] In this embodiment, the locking mechanism includes a fixing plate 601, which is bolted to one side of the mounting plate 302. A locking rod 602 is threaded onto the fixing plate 601, and a friction block 603 is bolted to one end of the locking rod 602. By rotating the locking rod 602, the locking rod 602 can move up and down along the threads of the fixing plate 601, thereby causing the friction block 603 to abut against the mounting shaft 201, thus locking the movement of the rotating sleeve 203 on the mounting shaft 201.

[0032] Working principle: When using this device, the winding seat 204 with the detection rope wound around it is moved to the goaf area, and the guide ring 506 is placed directly above the wiring position in the goaf area. At this time, the power assembly 303 is activated. The power assembly 303 drives the winding seat 204 to rotate through the first gear 304 and the second gear 305, causing one free end of the detection rope to extend from the winding seat 204. After passing through the guide plate 406, the guide seat 402, and the guide ring 506, the free end begins to be lowered vertically into the goaf area. At this time, the other end of the detection rope is inside the through hole 205, and a certain amount of slack is left at this end. After the detection rope enters the water accumulation area in the goaf area, it is inserted into the transient electromagnetic instrument to prevent the detection rope from being damaged. After multiple turns of winding on the shaft 201, during the winding seat 204's rotation and wire release process, the eccentric shaft 501 rotates along with the output end of the power assembly 303. The eccentric shaft 501 drives the connecting shaft 503 to move via the rocker arm 502. The connecting shaft 503 drives the push rod 504 to reciprocate along the through hole of the connecting rod 505. The push rod 504 drives the guide ring 506 to reciprocate back and forth, thereby causing the detection rope to sway to a certain extent. Even if the detection rope encounters an obstacle when it descends into the goaf, it is not easy to get stuck or bend, which is conducive to vertically entering the water accumulation area. After entering the water accumulation area, one end of the detection rope in the exit hole 205 is passed through the wire hole 104 and inserted into the transient electromagnetic instrument to observe the water accumulation situation in the goaf.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
