Technical Field

[0001] This utility model relates to the field of coal mine water level early warning technology, specifically a coal mine underground water prevention and control early warning device. Background Technology

[0002] Coal is the most important solid fuel and a type of combustible organic rock. It is formed by the gradual accumulation of thick layers of lush vegetation that grew over a certain geological period in suitable geological environments, and then buried underwater or in silt, undergoing natural coalification over a long geological period. my country's coalfields have complex hydrogeological conditions, and currently about 18% of my country's unexploited coal reserves are under serious threat from water hazards.

[0003] Existing underground water control early warning devices in coal mines typically utilize floats. When the water level rises, the floats inside the device rise to contact a certain structure, thereby triggering an alarm and achieving the early warning function.

[0004] However, the detection depth of this early warning method cannot be adjusted, making it unsuitable for coal mines with varying risk levels; furthermore, water flowing into the device can introduce some slag and soil, affecting the accuracy of the device's detection. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a coal mine underground water prevention and early warning device, which solves the problem of the inability to adjust the detection depth, while avoiding the influence of slag and soil on the detection structure.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a coal mine underground water control early warning device is proposed, comprising a threaded cylinder, a rotary motor, and an early warning mechanism. A drill bit is provided at the bottom of the threaded cylinder, and the rotary motor is connected to the top of the threaded cylinder. The early warning mechanism includes an installation rod and sensors. A plurality of through holes are provided in the threaded groove of the threaded cylinder, and an installation groove is provided inside the threaded cylinder, which communicates with the through holes. The installation rod is disposed in the installation groove, and a plurality of sensors are provided on the installation rod. The sensors are disposed inside the through holes, and a filter head is provided outside the through holes, which is threadedly connected to the through holes.

[0007] According to one embodiment of the present invention, a filter screen is provided on the filter head.

[0008] According to one embodiment of the present invention, the outer peripheral wall of the filter head is provided with a mounting plate, and the mounting plate is provided with a plurality of slots in a ring shape, the mounting plate being used to install the filter head.

[0009] According to one embodiment of the present invention, the mounting plate is equipped with a matching mounting head, and the mounting head is provided with a locking block, which is adapted to the locking slot.

[0010] According to one embodiment of the present invention, the rotary motor is fixedly mounted on the support plate, and its output end is connected to the top of the threaded cylinder. Auxiliary support components are provided on both sides of the support plate.

[0011] According to one embodiment of the present invention, the auxiliary support assembly includes a support cylinder and a support column. The support column is telescopically disposed inside the support cylinder. A spring is disposed inside the support cylinder, with one end of the spring connected to the inside of the support cylinder and the other end connected to the support column.

[0012] According to one embodiment of the present invention, a folding cover is provided at the bottom of the support plate, and the threaded cylinder is disposed inside the folding cover.

[0013] According to one embodiment of the present invention, the size of the mounting rod is adapted to the mounting groove.

[0014] According to one embodiment of the present invention, a handle is provided on the top of the support plate.

[0015] According to one embodiment of the present invention, a collection frame is provided at the bottom of the support plate, and the top of the folding cover is fixedly disposed inside the collection frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a rotary motor to drive a connected threaded cylinder to rotate. Since a drill bit is located at the bottom of the threaded cylinder, it drills into the ground during rotation. As the threaded cylinder penetrates deeper into the ground, a mounting rod with a sensor installed in its mounting groove, through a through-hole communicating with the threaded groove, allows the sensor to monitor the surrounding environment. When the data detected by the sensor exceeds a preset normal range, the early warning system receives the signal and activates corresponding early warning measures, such as issuing an audible and visual alarm, to remind personnel to take appropriate flood control measures.

[0018] 2. The filter screen on the filter head of this utility model can block impurities in the water, preventing them from entering the through-hole and contacting the sensor, thus ensuring the normal operation of the sensor. Simultaneously, because the slot on the mounting plate matches the locking block on the mounting head, when installing the filter head, simply align the locking block of the mounting head with the slot on the mounting plate and rotate it to complete the installation and fixation of the filter head; for disassembly, simply rotate the mounting head in the opposite direction. This facilitates the installation and replacement of the filter head, and allows for quick handling when the filter screen is clogged or damaged, ensuring the filtration effect and thus guaranteeing the accuracy of sensor monitoring. Furthermore, the annularly designed locking slot makes the installation more stable and less prone to loosening. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 4As shown, a coal mine underground water control early warning device includes a threaded cylinder 1, a rotary motor 2, and an early warning mechanism. A drill bit 11 is provided at the bottom of the threaded cylinder 1, and the rotary motor 2 is connected to the top of the threaded cylinder 1. The early warning mechanism includes an installation rod 3 and sensors 31. A plurality of through holes 12 are provided in the threaded groove of the threaded cylinder 1. An installation groove 13 is opened inside the threaded cylinder 1, and the installation groove 13 communicates with the through holes 12. The installation rod 3 is disposed in the installation groove 13, and a plurality of sensors 31 are provided on the installation rod 3. The sensors 31 are disposed inside the through holes 12, and a filter head 4 is disposed outside the through holes 12. The filter head 4 is threadedly connected to the through holes 12.

[0026] The rotary motor 2 is started, which drives the threaded cylinder 1 connected to it to rotate. Since the bottom of the threaded cylinder 1 is equipped with a drill bit 11, the drill bit 11 drills into the ground during rotation. As the threaded cylinder 1 continues to go deeper into the ground, the mounting rod 3 with a sensor 31 installed in its mounting groove 13, through the through hole 12 communicating with the threaded groove, enables the sensor 31 to monitor the surrounding environment.

[0027] During underground coal mine operations, surrounding water and other substances come into contact with the filter head 4. After being filtered by the filter screen 41 on the filter head 4, the water reaches the sensor 31. The sensor 31 transmits the sensed water level, water pressure, water quality, and other relevant data to the subsequent signal processing and early warning system, thereby enabling the monitoring of water control data in the coal mine. When the data monitored by the sensor 31 exceeds the preset normal range, the early warning system receives the signal and activates corresponding early warning measures, such as issuing audible and visual alarms, to remind workers to take appropriate water control measures.

[0028] The filter head 4 is provided with a filter screen 41; the outer peripheral wall of the filter head 4 is provided with a mounting plate 42, and the mounting plate 42 is provided with a plurality of slots 43 arranged in a ring. The mounting plate 42 is used to install the filter head 4; the mounting plate 42 is equipped with a matching mounting head 5, and the mounting head 5 is provided with a locking block 51, which is adapted to the slots 43.

[0029] The filter screen 41 on the filter head 4 blocks impurities in the water, preventing them from entering the through hole 12 and contacting the sensor 31, thus ensuring the normal operation of the sensor 31. The slot 43 on the mounting plate 42 is adapted to the locking block 51 on the mounting head 5. When installing the filter head 4, align the locking block 51 of the mounting head 5 with the slot 43 of the mounting plate 42 and rotate it to complete the installation and fixation of the filter head 4; when disassembling, simply rotate the mounting head 5 in the opposite direction.

[0030] The filter head 4 is designed for easy installation and replacement. When the filter screen 41 becomes clogged or damaged, it can be quickly addressed to ensure filtration efficiency and thus guarantee the accuracy of the sensor 31's monitoring. Simultaneously, the annularly designed slot 43 ensures a more secure installation and prevents loosening.

[0031] The rotary motor 2 is fixedly mounted on the support plate 6. The auxiliary support assembly includes a support cylinder 61 and a support column 62. The support column 62 is telescopically disposed inside the support cylinder 61. A spring 63 is disposed inside the support cylinder 61. One end of the spring 63 is connected to the inside of the support cylinder 61, and the other end is connected to the support column 62.

[0032] The support column 62 is telescopically mounted inside the support cylinder 61, and one end of the spring 63 inside the support cylinder 61 is connected to the inside of the support cylinder 61, while the other end is connected to the support column 62. During the drilling process where the rotary motor 2 drives the threaded cylinder 1 underground, when encountering uneven ground conditions, the support column 62 will automatically extend and retract according to the actual ground conditions under the action of the spring 63, adjusting the support height to provide stable support for the support plate 6 and the rotary motor 2.

[0033] The support plate 6 has a folding cover 7 at its bottom, and the threaded cylinder 1 is disposed inside the folding cover 7. The support plate 6 has a collection frame 8 at its bottom, and the top of the folding cover 7 is fixedly disposed inside the collection frame 8.

[0034] During the drilling process of the threaded cylinder 1, debris and other impurities will be ejected. The folding cover 7 gradually contracts as the threaded cylinder 1 is drilled in, preventing debris from being ejected into the surrounding environment.

[0035] The mounting rod 3 is sized to fit the mounting groove 13, allowing it to be installed tightly and securely within the groove. During the drilling and subsequent monitoring processes, the mounting rod 3 will not wobble or shift within the groove 13, ensuring the sensor 31 remains in a fixed position and accurately monitors the surrounding environment.

[0036] A handle 9 is provided on the top of the support plate 6. When handling or moving the early warning device, the operator can hold the handle 9 on the top of the support plate 6 to easily apply force and perform operations such as moving or adjusting the position of the device.

[0037] The working principle of this invention is as follows: The rotary motor 2 is started, driving the threaded cylinder 1 connected to it to rotate. Since the bottom of the threaded cylinder 1 is equipped with a drill bit 11, the drill bit 11 drills into the ground during rotation. As the threaded cylinder 1 continues to penetrate underground, the mounting rod 3 with a sensor 31, located in its mounting groove 13, monitors the surrounding environment through a through hole 12 connected to the threaded groove. During underground coal mine operations, surrounding water and other substances come into contact with the filter head 4. After being filtered by the filter screen 41 on the filter head 4, the water reaches the sensor 31. The sensor 31 transmits the sensed water level, water pressure, water quality, and other relevant data to the subsequent signal processing and early warning system, thereby achieving the monitoring of water control data in the coal mine. When the data monitored by the sensor 31 exceeds the preset normal range, the early warning system receives the signal and activates corresponding early warning measures, such as issuing audible and visual alarms, to remind workers to take appropriate water control measures.

[0038] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
