Description

Technical Field

[0001] This invention relates to the technical field of borehole gas leak prevention devices, specifically to borehole gas leak prevention devices. Background Technology

[0002] Mining, as a means of utilizing natural resources, requires excavation and drilling operations on mountains or terrain to extract flammable gases and materials deep underground, thus facilitating the application of these resources by humans. However, this process is often accompanied by certain dangers. As the drilling depth increases, the uncontrollability also increases. Therefore, a drilling device for monitoring methane gas is also used.

[0003] Traditional monitoring drilling devices lack a mechanism to synchronously monitor the pipeline vibration during drilling. This means they cannot isolate vibration interference signals generated by fluctuations during operation, making them susceptible to external interference and increasing the risk of drilling operations. Furthermore, traditional devices lack a real-time slag removal system, preventing the immediate removal of slag after entry. The integrated design of traditional drilling devices also increases the difficulty of maintenance after prolonged use, reducing their practicality. Therefore, we propose a drilling gas leakage prevention device. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-7A drilling gas leak prevention device includes a collection tank 1. A auger 2 is fixedly installed at the bottom of the collection tank 1. A slag discharge pipe 4 is rotatably connected to the inner wall of the auger 2. A vertical rod 6 and a first connecting pipe 7 pass through the top of the collection tank 1. An axial flow fan 3 is fixedly installed at the top of the first connecting pipe 7. A pressure tank 5 is located on the left side of the collection tank 1. A support pipe 11 is fixedly installed along the outer edge of the collection tank 1. A controller 10 is fixedly mounted at the top of the support pipe 11. A first wire 12 is fixedly installed at the output port of the controller 10. A junction box 15 is fixedly installed at the end of the first wire 12 away from the controller 10. A fourth wire 17 is fixedly installed at the output port of the junction box 15. A third wire 16 is fixedly installed at the bottom of the junction box 15. A laser methane sensor 8 and a carbon monoxide sensor 9 are respectively installed above the collection tank 1. A second wire 13 is fixedly installed on the left side of the carbon monoxide sensor 9. A first wire 18 and a second wire 19 are fixedly installed on the top of the laser methane sensor 8. A first drain pipe 18 is fixedly installed along the outer edge of the collection tank 1. The first exhaust pipe 20 has a second connecting pipe 21 fixedly sleeved at its top end, and a second exhaust pipe 30 fixedly mounted at its top end. A support rod 22 is fixedly mounted on the left side of the auger 2. A pressure-connecting air pipe 23 passes through the outer wall of the pressurization tank 5. A push valve 24 is fixedly mounted at the top end of the support rod 22. A vibrator 26, a first fixing block 27, and a second fixing block 29 are fixedly mounted on the outer edge of the collecting tank 1. A water valve 25 is rotatably connected to the outer wall of the second fixing block 29. A filter 28 is fixedly mounted on the top of the first fixing block 27. A first limit rod 14 passes through the outer wall of the water valve 25. Through the junction box 15, the third wire 16, the fourth wire 17, the second wire 13, the first wire 18, and the second wire 19, the detection devices in the device can be connected in series. When the gas pressure of the detection part is too high, the controller 10 can control the operating status of each unit, thereby achieving automatic detection and further improving the safety of the device during operation.

[0027] The ends of the first wire 18 and the second wire 19 furthest from the laser methane sensor 8 are fixedly assembled to the top of the pressurization tank 5 and the push valve 24, respectively. An observation window is provided on the outer edge of the collection tank 1, and a drilling interface is provided on the outer edge of the upright 6. The observation window allows the user to view the working status inside the collection tank 1, thereby improving the user's monitoring of the drilling device. The drilling interface facilitates the user's installation of the drilling equipment, thereby improving the user's installation efficiency and working efficiency.

[0028] The second fixing block 29 is fixedly provided with a second limiting rod on its outer wall, and the water valve 25 is rotatably connected to the outer wall of the second fixing block 29 through the cooperation of the first limiting rod 14 and the second limiting rod. The second limiting rod can fix the water valve 25, so that the user can deliver the water source to the pole 6 for dust suppression after connecting the external water source, thereby achieving the effect of automatic output of slag and improving the practicality of the drilling device.

[0029] The vibrator 26 is electrically connected to the push valve 24. The inside of the collecting tank 1 is pressurized through the cooperation of the pressurization tank 5 and the pressurized air pipe 23. The inside of the upright 6 is equipped with a sprayer. The push valve 24 can cooperate with the vibrator 26 to reduce the vibration force on the collecting tank 1 and various detection devices, thereby reducing the interference on the detection devices and improving the accuracy of data acquisition by the drilling device. The sprayer can spray water on the slag, thereby improving the dust reduction effect of the drilling device, making it easier for users to recycle the slag and further improving the user's work efficiency.

[0030] The device includes three support tubes 11, which are evenly distributed along the outer edge of the collecting tank 1. The support tubes 11 support the laser methane sensor 8, carbon monoxide sensor 9, and controller 10, thereby ensuring the stability of the laser methane sensor 8, carbon monoxide sensor 9, and controller 10 during operation. At the same time, while maintaining the operation functions of the three, the space occupied by the drilling device is reduced, thereby reducing the floor area of ​​the drilling device and making the drilling device compact and aesthetically pleasing.

[0031] The first wire 12, the end furthest from the controller 10, and the second wire 13, the end furthest from the carbon monoxide sensor 9, are both fixedly mounted to the right side of the junction box 15. The third wire 16, the end furthest from the junction box 15, is fixedly mounted to the outer edge of the collection tank 1. The junction box 15 can connect the laser methane sensor 8 and the carbon monoxide sensor 9 to the controller 10, thereby enabling the controller 10 to control the laser methane sensor 8 and the carbon monoxide sensor 9 in a timely manner, thus ensuring the safety of workers during operation.

[0032] The end of the fourth wire 17 furthest from the junction box 15 is fixedly mounted to the left side of the laser methane sensor 8. The laser methane sensor 8, carbon monoxide sensor 9, and controller 10 are all fixedly connected to the collection tank 1 through the support tube 11. By utilizing the cooperation of the fourth wire 17 and the junction box 15, the installation process of the drilling device is simplified, thereby reducing the difficulty of operating the drilling device, thus improving the user's installation efficiency and facilitating the user's later maintenance.

[0033] The back of the collecting tank 1 is fixed with an LED display screen, and the upright 6 and the first connecting pipe 7 are both made of galvanized metal. The LED display screen can display the data collected by the drilling device in a timely manner, which makes it convenient for users to collect data. Galvanized metal has certain hardness and wear resistance, which can extend the service life of the upright 6 and the first connecting pipe 7, thereby reducing the maintenance cost of the device.

[0034] The upright 6 and the first connecting pipe 7 are connected by the axial flow fan 3, and the second connecting pipe 21 is fixedly connected to the collecting bucket 1 through the first exhaust pipe 20. The cooperation between the axial flow fan 3 and the first connecting pipe 7 can suck the slag into the upright 6, thereby discharging the slag into the inside of the collecting bucket 1. In this way, the slag is transported to the outside of the collecting bucket 1 by the cooperation of the auger 2 and the slag discharge pipe 4, thereby improving the practicality of the drilling device.

[0035] The working principle is as follows: First, the pressurized air pipe 23 is installed into the pressurization tank 5. Then, the pressurization tank 5 is connected to the collection tank 1. Subsequently, the spray water source is connected to the sprayer. During drilling, after the spray settles, the pressurization tank 5 pressurizes the inner wall of the slag discharge pipe 4 to achieve pneumatic slag discharge from the bottom. Then, the auger 2 automatically discharges the slag, realizing simultaneous drilling and slag discharge, which is automated. When the drilling gas exceeds the preset values ​​of methane and carbon monoxide, the controller 10 starts working, the slag discharge pipe 4 stops rotating, and the sprayer also stops spraying to prevent a large amount of water vapor from entering the pipeline with negative pressure. When the methane and carbon monoxide values ​​in the borehole drop back to normal values, the slag discharge pipe 4 continues to work automatically to discharge slag, and the sprayer also automatically turns on and starts working normally. Thus, this device solves the problem of difficult slag discharge during drilling, which required time-consuming and labor-intensive manual observation and cleaning. It achieves slag discharge as soon as it enters, realizing a fully automated effect.
