Description

Technical Field

[0001] The invention relates to the field of coal mine water hazards, and in particular to a coal mine water hazard early warning and emergency drainage integrated device. Background Art

[0002] In the long history of coal mining, water hazards have always been a major hidden danger threatening safe production. With the development of the times, the scale of coal mining has continued to expand, the mining depth has continued to increase, the geological conditions have become more complex, and the water hazard problem has become increasingly serious. The traditional coal mine water hazard early warning mainly relies on manual monitoring using some simple instruments and equipment. Workers need to go down the mine regularly and observe key parameters such as water level and water pressure in the mine based on experience and a small number of simple tools such as simple water level gauges and pressure gauges. However, the collection and analysis of these instrument data mostly require manual operation, which is inefficient and cannot issue early warning signals in a timely and effective manner. In addition, the size of the drainage outlet for emergency drainage in traditional coal mines is usually fixed. In this way, when facing water hazards, once the scale of the water hazard is large and the amount of water gushing increases dramatically, the drainage speed of the fixed drainage outlet is difficult to meet the actual drainage needs, resulting in a large amount of accumulated water that cannot be discharged in time, which may lead to serious consequences such as tunnel flooding and equipment damage, posing a great threat to coal mine safety production.

[0049] When the photoelectric sensor 8 is triggered, the controller 15 will respond immediately and start the small cylinder 505. The small cylinder 505 drives the tooth plate 506 to move smoothly, and then the tooth 503 engaged with it starts to rotate, prompting the lower drainage cover 502 to rotate a certain angle.

The lower drainage cover 502 rotates to a predetermined angle to ensure that the second leakage port 510 is accurately connected with the first leakage port 504, thereby achieving efficient drainage.

[0051] Water inlet holes are provided around the lower end of the outer wall of the detection box 1, and the inner wall of the water inlet hole is provided with a filter screen 9. The filter screen 9 can effectively filter out impurities, particles and other foreign matter in the water to prevent these debris from entering the interior of the detection box 1 and causing damage to the buoy 7, thereby extending the service life of various components of the device and ensuring the stable operation of the water hazard warning function. At the same time, it also prevents impurities from clogging the drainage channel and ensures the normal operation of the drainage system.

[0052] The outer wall of the upper drain cover 501 is snap-fitted with the inner wall of the connection box 2, and the lower drain cover 502 is snap-fitted with the card plate of the inner wall of the connection box 2, which ensures the stability of the positions of the upper drain cover 501 and the lower drain cover 502 in the connection box 2.

[0053] A plurality of leakage holes 508 are provided at the edges of the upper surfaces of the upper drainage cover 501 and the lower drainage cover 502. The plurality of leakage holes 508 provided on the upper drainage cover 501 and the lower drainage cover 502 correspond to each other, further increasing the number of drainage channels and improving drainage efficiency. When a water disaster occurs, the accumulated water can be discharged more quickly, effectively reducing the speed of water level rise and alleviating the harm of the accumulated water to the mine.

[0054] A mounting groove 10 is provided at the front end of the other side of the upper surface of the detection box 1, a transmission module 11 is provided at the lower end of the inner wall of the mounting groove 10, a controller 15 is provided in the middle of the inner wall of the mounting groove 10, and a snap-in plate 12 is snap-fitted at the upper end of the inner wall of the mounting groove 10, providing a stable and safe installation position for the transmission module 11 and the controller 15, and the snap-in plate 12 plays a good protective role to ensure their normal operation, and the transmission module 11 can timely transmit the water level information detected by the photoelectric sensor 8 to the outside world, and the controller 15 can respond quickly according to the preset program to control the operation of equipment such as the small cylinder 505, thereby realizing the automation and intelligent control of water hazard warning and emergency drainage.

[0055] The upper end of the outer wall of the buoy 7 slides with the upper end of the inner wall of the detection box 1, and the upper end of the positioning plate 6 fits with the lower end of the buoy 7, so that the buoy 7 can slide up and down stably in the detection box 1. The positioning plate 6 plays a role in positioning and auxiliary stabilization, ensuring that the buoy 7 is always in the correct position during the rising process.

[0056] Working principle: When water flows in the mine, the water flows into the detection box 1 through the water inlet holes opened around the lower end of the outer wall of the detection box 1. The filter screen 9 arranged on the inner wall of the water inlet hole can effectively filter impurities in the water to prevent them from damaging the internal components. As the water level rises, the buoy 7 in the detection box 1 begins to rise under the buoyancy of the water. The upper end of the outer wall of the buoy 7 slides with the upper end of the inner wall of the detection box 1, and the upper end of the positioning plate 6 fits with the lower end of the buoy 7, which ensures the stability of the buoy 7 during the rising process.

[0057] When the buoy 7 rises to a certain height, its upper end contacts the photoelectric sensor 8 provided at the upper end of the inner wall of the detection box 1. After the photoelectric sensor 8 is triggered, the optical signal is converted into an electrical signal, which is transmitted to the controller 15 installed in the middle of the inner wall of the front mounting groove 10 on the other side of the upper surface of the detection box 1. At the same time, the transmission module 11 will also transmit the signal containing the water level information to the outside world through its own communication method such as Bluetooth, Wi-Fi, etc., so that relevant personnel or systems can obtain water hazard warning information in time. When the controller 15 receives the signal from the photoelectric sensor 8, it determines that the water level has reached the dangerous warning value, and immediately starts the small cylinder 505 fixed on the inner wall of the connecting groove 13 of the fixed box 4. The output end of the small cylinder 505 pushes the tooth plate 506 to move, and the tooth plate 506 is meshed with the teeth 503 fixedly connected to the outer wall of the lower drainage cover 502. The teeth 503 rotate in the rotating groove 14, and the inner wall of the rotating groove 14 fits with the first ball 509, so that the teeth 503 rotates more smoothly. At the same time, the slide plate 511 fixed at the upper edge of the lower drain cover 502 slides in the slide groove 507 opened at the lower edge of the upper drain cover 501. The inner wall of the slide groove 507 fits with the second ball 512, which ensures the stability of the lower drain cover 502 when rotating. As the lower drain cover 502 rotates to a certain angle, the second water leakage port 510 that was originally not connected is connected with the first water leakage port 504, the drainage channel is widened, and the drainage volume is significantly increased, so that the accumulated water in the mine can be quickly discharged to cope with the threat of water damage;

[0058] Under normal circumstances, the outer wall of the upper drain cover 501 is snap-fitted with the inner wall of the connection box 2, and the lower drain cover 502 is snap-fitted with the card plate of the inner wall of the connection box 2. At this time, the drainage channel is in a relatively small state, and a small amount of normal water may be drained through the corresponding leakage holes 508 opened at the edges of the upper surfaces of the upper drain cover 501 and the lower drain cover 502.

Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device.
