Problems solved by technology

In the past construction process, during the drilling construction process, when the water came out of the hole, if it was too late to pull out the drill hole, the only option was to put the drill pipe into the hole, and then close the valve to stop the water. If the drill pipe was pulled out, the hole would be There will be water gushing out. When the water gushing out of the borehole is large and the pressure is high, the gushing water will rush directly to the drilling rig equipment, which will cause damage to the drilling rig equipment. At the same time, the gushing water will also affect the The impact of the crowd around the drilling equipment will affect the safety of people

Embodiment 1

[0035] like Figure 1-6 Shown a kind of water exploration and drainage hole blowout preventer, including drill pipe 1, ore body 2 and drill hole 3, the drill pipe 1 is inserted into the ore body 2 through the drilling rig equipment and forms a drill hole on the ore body 2 3. The port of the borehole 3 located on the outer wall of the ore body 2 is provided with a shunt mechanism for guiding and shunting the gushing water flow inside the borehole 3. The shunt mechanism includes a fixed plate 4 with a circular hole 41 in the center, which is fixed on a fixed plate. The diversion cylinder 8 on the disk 4 and in the annular structure, the diversion cylinder 8 is hollow inside and the upper and lower ends are open, and the diversion cylinder 8 and the circular hole 41 are arranged concentrically, and the inner diameter of the diversion cylinder 8 is equal to the circular hole 41 The diameter of the diversion cylinder 8 and the circular hole 41 is larger than the diameter of the bor...

Embodiment 2

[0038] The difference between embodiment 2 and embodiment 1 is that, as Figure 7-9As shown, the bottom end of the fixed plate 4 is provided with a protective mechanism for gathering the water flow at the lower end of the circular hole 41. The adjustment mechanism on the flow cylinder 8 and the telescopic adjustment of the bellows 12, the upper port of the bellows 12 is fixedly connected with the bottom end of the fixed plate 4 through the upper connecting ring 13, and the lower port of the bellows 12 is fixedly connected with the borehole 3. The lower connecting ring 16, which covers the port, can cover the area between the port of the borehole 3 and the fixed plate 4 through the corrugated pipe 12, so that more water flowing from the borehole 3 can flow into the guide tube 8, in order to reduce the outflow of the water flow from the lower port of the diversion cylinder 8, improve the gathering effect of the water divider on the gushing water flow, and at the same time enhanc...

Abstract

The invention discloses a blowout preventer for water exploration and discharge drilling and a working method thereof, which belong to the technical field of coal mine safety production and include a drill pipe, an ore body and a drill hole. The drill pipe is plugged into the mine body through drilling equipment and A borehole is formed on the ore body, and the port of the borehole is located on the outer wall of the ore. A diversion mechanism is provided to guide and divert the water flowing out of the borehole. The diversion mechanism includes a fixed plate with a round hole in the center . The guide tube which is fixed on the fixed plate and has a ring structure. In the present invention, when a large amount of water gushes out inside the borehole, most of the gushing water can be diverted through the diversion cylinder, and finally discharged from the water outlet pipe at the water outlet on the diversion cylinder, thereby preventing the gushing water flow It will directly rush to the drilling rig equipment to protect the drilling rig equipment, and at the same time, it can also reduce the possibility of the impact of the gushing water flow on the people around the drilling rig equipment, so as to realize the protection of people.

Description

technical field [0001] The invention relates to the technical field of safe production in coal mines, and in particular relates to a blowout prevention water separator for water exploration and drainage holes. Background technique [0002] At present, in the mining industry, geophysical prospecting cannot accurately describe the water-bearing state in the formation, but can only roughly delineate the water-bearing area. [0003] According to the regulations, in the process of water exploration and drainage construction, it is necessary to accurately grasp the water output of the detection and drainage holes and the water inflow volume of the drilling holes, so as to provide basic information for the water detection and drainage work. In the previous construction process, during the drilling construction process, when water came out of the hole, if it was too late to pull out the drilling hole, the only way was to put the drill pipe into the hole, and then close the valve to ...
