It is necessary to constantly adjust the negative pressure at the borehole opening. During the process of controlling the negative pressure, water and coal slag can easily be drawn into the main system, causing system fluctuations.

[0003] Gas-water separators are key equipment in high-gas and coal and gas outburst mines. Traditional gas-water separators suffer from problems such as difficulty in adjusting the negative pressure at the orifice and difficulty in draining water. Utility Model Content

[0018] This utility model provides an embodiment:

[0019] like Figure 1 As shown, an integrated blowout prevention device includes: a water discharger 1, a pneumatic control box 2, pneumatic valves, and connecting pipe fittings. The water discharger 1 includes an upper cylinder and a lower cylinder connected by a first connecting pipe fitting 4.1. The upper cylinder has ports at its upper end for connecting the orifice airbag, water tank, water tank cover, tail pump, and orifice backup negative pressure, respectively. The upper end of the upper cylinder is also connected to two blowout prevention airbags via connecting pipe fittings. These two airbags connect two negative pressure pipelines. One of the blowout prevention airbags has a #5 pneumatic valve 3.5 at its end furthest from the water discharger 1. A #2 pneumatic valve 3.2 is installed on the first connecting pipe fitting 4.1. A #4 pneumatic valve 3.4 is installed at the bottom end of the lower cylinder. Pneumatic valves 3.2, 3.4, and 3.5 are connected to the pneumatic control box 2, which has handles for controlling the operation of the pneumatic valves. The drilling rig operator controls water release and negative pressure via a pneumatic control box.

[0020] In this embodiment, the eight-hole drainer serves as the core execution unit, supporting independent drainage of multiple gas streams; the pneumatic control box incorporates a precision control module, enabling both manual and automatic operation; the 8-point piping system, coupled with standard pneumatic valves, forms a stable gas transmission channel; and the high-pressure air duct, along with connecting straight and elbow fittings, constitutes a flexible pneumatic control network. The entire device seamlessly connects to the main gas extraction pipeline via a 4-inch negative pressure pipe, constructing a complete auxiliary control system for gas extraction.

[0021] In addition, a pneumatic directional valve is installed inside the pneumatic control box 2. The pneumatic directional valve is controlled by a handle, and the pneumatic control box 2 is located in the drilling rig operator's operating position. The pneumatic directional valve includes a water discharge control valve connected to pneumatic valves 3.2 (2#) and 3.4 (4#) and a negative pressure control valve connected to pneumatic valve 3.5 (5#). The pneumatic directional valve converts the compressed air signal into mechanical power, which is transmitted to the corresponding pneumatic valve through a high-pressure air pipe.

[0022] The upper and lower cylinders are connected by a second connecting pipe 4.2. The second connecting pipe 4.2 and the first connecting pipe 4.1 are located on opposite sides of the water dispenser 1. A manual valve 3.1 (#1) is installed on the end of the second connecting pipe 4.2 near the upper cylinder, and a manual valve 3.3 (#3) is installed on the bottom of the lower cylinder opposite to the pneumatic valve 3.4 (#4). Manual valves 3.1 and 3.3 correspond to manual mode. Manual valve 3.3 can be used to release air during automatic water dispensing, thereby accelerating the water dispensing speed.

[0023] A baffle 5 is installed on the upper part of the inner cavity of the upper cylinder near the #2 pneumatic valve 3.2. The baffle 5 is used to intercept impurities floating on the liquid surface to prevent pipe blockage.

[0024] Working principle analysis:

[0025] Under normal conditions, #1, #3, and #4 are off, and #2 is on.

[0026] Water discharge status: #2 is closed, #4 is open;

[0027] Anti-blowout negative pressure on: Open valve #5.

[0028] This device is based on pneumatic control principles and is remotely operated via a multi-functional switch handle on the pneumatic control box. When the operator moves the control handle, the pneumatic reversing valve inside the control box converts the compressed air signal into mechanical power, which is transmitted to the pneumatic gate valve actuator through a high-pressure air duct. On one hand, the pneumatic gate valve opens and closes rapidly, precisely controlling the discharge of water accumulated in the eight-hole drain, effectively preventing water from clogging the extraction pipeline; on the other hand, the device can instantly adjust the negative pressure at the orifice, achieving dynamic balance of extraction pressure by synchronously controlling the gate valves of each branch pipeline. The entire operation process requires no on-site human intervention, significantly improving the automation level and operational safety of the gas extraction system.

[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
