[0030] The present invention sets a mounting seat assembly 10, a water storage tank 20, a gas extraction assembly 30 and a drainage assembly 40 to work together, so that the gas extraction pipe 31 can extract gas at the main gas release position in the coal seam, effectively reducing the local gas concentration in the tunnel, thereby solving the potential safety hazard and ensuring the safety of the entire mine tunnel, equipment and workers during coal mining. It also allows the drainage pipe 41 to transport the liquid in the accommodating chamber 21 to the bottom of the tunnel, effectively solving the water gushing problem, avoiding the workers and equipment from being sprayed by the gushing water, which is more beneficial to the health of the workers and the stable operation of the equipment, and ensuring the safe production working environment of the excavation working face; by arranging the drainage pipe 41 along the top plate 50 and the side wall 70 of the tunnel , effective avoidance of personnel and equipment in the tunnel is achieved. By arranging the gas extraction pipe 31 along the roof 50 and / or the side wall 70 of the tunnel, effective avoidance of personnel and equipment in the tunnel is also achieved, thereby ensuring smooth passage of personnel and equipment; by arranging the projection of the penetration hole 60 to be located within the projection of the water storage tank 20, the gas extraction effect and the water collection effect are guaranteed; the present invention has a simple structure and low cost, is easy to assemble and subsequently maintain, and can be quickly installed and used when water and gas gush out of the anchor hole in the tunnel; at the same time, the tunnel roof gas and water collection device proposed by the present invention can be directly used before the anchor cable or anchor rod is withdrawn, is not affected by the anchor cable or anchor rod, and can be reused, which is suitable for large-scale promotion and use.

[0031] like Figure 1 and Figure 2 As shown, the mounting seat assembly 10 includes multiple groups of mounting parts, and the mounting parts include a base 11 and a movable seat 12. The base 11 is detachably arranged on the top plate 50, and the movable seat 12 is hinged to the base 11 through a universal ball, and the movable seat 12 is connected to the water tank 20; wherein, the multiple groups of mounting parts are arranged at circumferential intervals around the water tank 20, and the multiple mounting parts jointly support the water tank 20.

[0032] By setting up a mounting seat assembly including a base 11 and a movable seat 12, a universal ball joint is used to achieve stable installation of the water tank 20 on the irregular tunnel roof 50, thereby improving the adaptability and stability of the device in complex environments; the design of multiple groups of mounting parts jointly supporting the water tank 20 ensures uniform force on the water tank 20, extends the service life of the device, and reduces maintenance costs.

[0033] like Figure 1As shown, the tunnel roof gas and water collection device also includes a driving assembly and a detection sensor. The driving assembly is detachably arranged on the roof 50 and is drivingly connected to the water tank 20; the detection sensor is used to detect whether there is an object under the water tank 20; wherein, when the detection sensor does not detect that there is an object under the water tank 20, the driving assembly can drive the water tank 20 to tip over, so as to tip the water in the accommodating chamber 21 to the bottom of the tunnel.

[0034] By setting up a driving component and a detection sensor, it is possible to automatically detect whether there is an obstacle under the water tank 20, thereby avoiding possible damage to personnel or equipment during dumping, and improving the safety and intelligence level of the device; by setting up a detection sensor, the water accumulated in the water tank 20 can be dumped immediately to prevent excessive water from affecting the gas extraction efficiency and maintain the continuous and efficient operation of the device.

[0035] like Figure 1 As shown, the tunnel roof gas and water collection device also includes a liquid level sensor, which is arranged in the accommodating chamber 21 and is used to detect the liquid level height in the accommodating chamber 21; wherein, when the liquid level sensor detects that the liquid level height is higher than the set value and the detection sensor does not detect that there is an object under the water tank 20, the driving component drives the water tank 20 to dump to empty the accommodating chamber 21.

[0036] By setting a liquid level sensor, the liquid level in the accommodating chamber 21 can be accurately controlled, and the problems caused by excessive or insufficient extraction can be avoided by coordinating the gas extraction and drainage process. By setting a central controller, the power of the driving fan can be adjusted according to the data monitored by the gas concentration sensor, realizing the intelligent management of gas extraction and improving the safety and efficiency of gas extraction.

[0037] like Figure 1 As shown, the periphery of the opening 22 of the water tank 20 is in contact with the top plate 50 or has a gap; and / or the drain pipe 41 and / or the gas extraction pipe 31 adopts a retractable hose; the connection position of the drain pipe 41 and the accommodating chamber 21 is lower than the connection position of the gas extraction pipe 31 and the accommodating chamber 21.

[0038] By providing the drainage pipe 41 and / or the gas extraction pipe 31, the flexibility of the pipeline layout is increased, the undulation of the inner wall of the tunnel and the movement of the equipment are adapted, and the versatility of the device is improved. The drainage pipe 41 and the gas extraction pipe 31 are designed at different connecting positions in the accommodating chamber 21, which ensures the gas extraction efficiency while avoiding the entry of water during the extraction process, thereby optimizing the extraction and drainage process.

[0039] like Figure 1 As shown, the water tank 20 is a stepped cylindrical structure, and the size of the opening 22 of the water tank 20 is larger than the bottom size of the water tank 20 .

[0040] By designing the structure of the water tank 20, the size of the opening 22 is larger than the bottom size, which effectively increases the ability to collect and contain gas and water and reduces the need for frequent cleaning or replacement. At the same time, the stepped structure not only ensures sufficient volume, but also enhances the structural stability of the water tank 20 and improves the overall durability of the device.

[0041] The quick-release design of the water tank 20 and the quick-connect design of the interface greatly improve the installation and maintenance efficiency of the device. In addition, the use of highly corrosion-resistant, high-temperature-resistant and wear-resistant materials ensures the long-term stable operation of the device in harsh environments, providing strong technical support for coal mine safety production.

[0042] like Figure 1 As shown, the gas extraction component 30 also includes a driving fan and a collecting tank. The driving fan and the collecting tank are respectively connected to the gas extraction pipe 31. The driving fan is used to drive the gas extraction pipe 31 to extract the gas in the accommodating chamber 21 and transport it to the collecting tank for storage.

[0043] By providing a driving fan and a collecting tank, it is ensured that the gas gushing out from the penetration hole 60 can be effectively and safely extracted and stored, reducing the risk of gas accumulation in the tunnel; by providing a collecting tank, a temporary storage space is provided for the gas, which facilitates the subsequent recycling of the gas and promotes the efficient recycling of resources.

[0044] like Figure 1 As shown, the tunnel roof gas and water collection device also includes a central controller and a gas concentration sensor. The gas concentration sensor is used to detect the gas concentration in the tunnel; the central controller is electrically connected to the gas concentration sensor and the driving fan respectively; the central controller adjusts the power of the driving fan accordingly according to the gas concentration detected by the gas concentration sensor.

[0045] By setting up the linkage between the central controller, gas concentration sensor and driving fan, the gas extraction efficiency can be dynamically adjusted according to the gas concentration in the tunnel, thus avoiding waste of resources and improving the safety and economy of extraction.

[0046] like Figure 1 As shown, a mounting seat assembly 10, a water storage tank 20, a gas extraction assembly 30 and a drainage assembly 40 form a group of functional structures, and the functional structures are multiple groups, and the multiple groups of functional structures are arranged in a one-to-one correspondence with the penetration holes 60 of multiple anchor cables or anchor rods.

[0047] By providing a mounting base assembly 10, a water storage tank 20, a gas extraction assembly 30 and a drainage assembly 40 to form a group of functional structures, and correspondingly arranging a plurality of penetration holes 60, multi-point rapid collection of gas and water on the tunnel roof is achieved, the coverage of the device is enhanced, and the overall extraction efficiency is improved.

[0048] like Figure 1 As shown, the tunnel roof gas and water collection device also includes a filter screen, which is arranged at the connection between the drain pipe 41 and the accommodating chamber 21 to filter the substances entering the drain pipe 41.

[0049] By setting a filter net at the connection point between the drain pipe 41 and the accommodating chamber 21, impurities in the water are effectively filtered, preventing the drain pipe 41 from being blocked, and ensuring the smooth drainage process; the discharge of filtered water reduces pollution to the underground environment of the coal mine, meeting the requirements of environmentally friendly mining.

[0050] The specific working process and principle of an embodiment of the present invention are now described in detail as follows:

[0051] The device for quickly collecting water and gas at the anchor hole position on the top plate 50 of the excavation working face includes a trapezoidal cubic water storage tank 20 with an opening 22 on the upper part, a 50mm straight pipe is welded on the left side of the water storage tank 20 near the upper opening, and is used to connect the 75mm gas extraction pipe 31; a 50mm straight pipe is welded on the right side of the water storage tank 20 near the bottom direction, and is used to connect the 75mm drainage pipe 41;

[0052] When in use, the water storage tank 20 is hung on the top plate 50 around the penetration hole 60, and the gas gushing out of the penetration hole 60 enters the extraction system through the upper opening and the gas extraction pipe 31, and the gushing water enters the drainage pipe 41 through the lower opening and is discharged to the tunnel floor below the side wall 70;

[0053] Since the inner wall of the underground tunnel is usually uneven, the inner wall of the tunnel needs to be processed before the water tank 20 is hung and installed so that the water tank 20 can be installed smoothly. In view of this situation, a water tank 20 mounting seat assembly 10 is designed. The mounting seat assembly 10 includes a base 11, a universal ball and a movable seat 12. The base 11 and the universal ball structure are fixed together. The base 11 can be fixed to the tunnel side wall 70 or the top plate 50 by expansion bolts. A spherical cavity communicating with the outside is provided in the mounting seat assembly 10, and the spherical joint is hinged in the spherical cavity. The water tank 20 is fixed to the mounting seat assembly 10 by bolts to achieve its own all-round adjustment, and there is no need to select the installation position. For details, please refer to Figure 1 and Figure 2 ;

[0054] When water and gas gush out of the anchor cable hole in the tunnel, it can be quickly installed and used to prevent gas from flowing into the tunnel area. At the same time, the water gush out of the anchor cable hole can be led to one side of the tunnel to avoid workers being exposed to water during operation.

[0055] The present invention can be used directly before the anchor cable is withdrawn, is not affected by the anchor cable, can be used until the gas in the anchor cable hole is stable, and then the hole is sealed and continuously pumped out, and the present invention can be reused.

[0056] In terms of cost, welding the trapezoidal cube water tank 20 requires 5 kg of steel, calculated at 8,500 yuan / ton, so one trapezoidal cube water tank costs 42.5 yuan; using a 75mm hose for 15 meters, 25 yuan / meter, 375 yuan; each set of equipment costs 417.5 yuan; based on the normal excavation of 10m per shift at the excavation face, the coal volume per meter is 30.9 tons, and 309 tons of coal are produced per shift. Calculated at 220 yuan per ton of coal at Baode Coal Mine, the coal produced by the excavation face per shift is sold at 67,980 yuan; calculated based on the abnormal gas outflow from the anchor hole causing the gas to exceed the limit and affect the excavation production for at least 2 shifts, the direct economic benefit reaches 67,980*2=135,960 yuan; the use of the tunnel roof gas and water collection device proposed by the present invention can reduce the probability of gas exceeding the limit when the anchor hole gas of the excavation face gushes abnormally, thereby ensuring that the excavation face has a safe production working environment.

[0057] In summary, the present invention provides a tunnel roof gas and water collection device, which can cooperate with the installation base assembly 10, the water storage tank 20, the gas extraction assembly 30 and the drainage assembly 40 to extract gas at the main gas release position in the coal seam, effectively reducing the local gas concentration in the tunnel, thereby solving the potential safety hazard and ensuring the safety of the entire mine tunnel, equipment and personnel during coal mining. The drainage pipe 41 can also transport the liquid in the accommodating chamber 21 to the bottom of the tunnel, effectively solving the water gushing problem and preventing the personnel and equipment from being sprayed by the gushing water, which is more conducive to the health of the personnel and the stable operation of the equipment, and ensuring the safe production working environment of the excavation working face. By arranging the drainage pipe 41 along the roof of the tunnel 50 and the side wall 70 of the tunnel, effective avoidance of personnel and equipment in the tunnel is achieved. By arranging the gas extraction pipe 31 along the roof 50 and / or the side wall 70 of the tunnel, effective avoidance of personnel and equipment in the tunnel is also achieved, thereby ensuring smooth passage of personnel and equipment; by arranging the projection of the penetration hole 60 to be located within the projection of the water storage tank 20, the gas extraction effect and the water collection effect are guaranteed; the present invention has a simple structure and low cost, is easy to assemble and subsequently maintain, and can be quickly installed and used when water and gas gush out of the anchor hole in the tunnel; at the same time, the tunnel roof gas and water collection device proposed by the present invention can be directly used before the anchor cable or anchor rod is withdrawn, is not affected by the anchor cable or anchor rod, and can be reused, so it is suitable for large-scale promotion and use.
