At the same time, it studies the earth's geological structure, rock composition, and paleontological evolution, etc., to provide basic data and scientific basis for mineral resource development, environmental protection, disaster prevention, and other work.

[0003] Among them, geological exploration does require the use of a variety of equipment, and drilling rigs are one of the indispensable equipment for geological exploration, which is used to drill groundwater sources or conduct geological exploration sampling.

Therefore, a new technical solution needs to be designed to solve the problem, which can effectively support the middle part of the drill rod. Utility Model Content

[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: a drilling straightening device for geological exploration, including a drill pipe 1, multiple groups of drill pipes 1 are provided, a first mounting ring 12 is fixedly installed on one side of the outer wall of multiple groups of drill pipes 1, a second mounting ring 13 is fixedly installed on the other side of the outer wall of multiple groups of drill pipes 1, and a straightening support mechanism is installed between adjacent two groups of the first mounting ring 12 and the second mounting ring 13;

[0021] The straightening support mechanism includes multiple groups of arc-shaped brackets 2 fixedly installed at equal intervals between the first mounting ring 12 and the second mounting ring 13, an airbag 21 installed inside multiple groups of arc-shaped brackets 2, and a pressure gauge 22 communicated and installed on one side of the airbag 21.

A drill bit is fixedly installed at one end of one side of the drill pipe 1, and the drill bit is rotatably connected to the drill hole 11. Multiple groups of drill pipes 1 are all distributed inside the drill hole 11.

[0022] In this technical solution, an external air pump is docked with the airbag 21 inside the straightening support mechanism, and the airbag 21 inside multiple groups of arc-shaped brackets 2 is slowly inflated. After the airbag 21 continuously expands, it can effectively support the middle part of multiple groups of arc-shaped brackets 2, not only further straighten the drill pipe 1 effectively, but also support and protect multiple groups of arc-shaped supports.

[0023] In some technical solutions, an air outlet pipe 23 is communicated and installed on the other side of the airbag 21, and a solenoid valve 24 is fixedly installed at the other end of the air outlet pipe 23.

[0024] In this technical solution, through the pressure gauge 22 communicated and installed on one side of the airbag 21, the air pressure inside the airbag 21 can be detected at all times. When the air pressure inside the airbag 21 reaches the set value of the pressure gauge 22, a signal will be sent to the control processor to control the solenoid valve 24 at the port of the air outlet pipe 23. Not only the gas inside the airbag 21 is discharged to protect the airbag 21, but also the control processor receiving the signal will synchronously transmit the signal to the operator's central control computer to warn the operator that the drill pipe 1 is squeezed by the mountain body.

[0025] In some technical solutions, a fixing piece 32 is fixedly installed on the side wall of each group of the first mounting rings 12, and each group of fixing pieces 32 is fixedly installed with multiple groups of pressure gauges 22 through bolts respectively, so as to fix the pressure gauges 22.

[0026] In this technical solution, when each group of drill rods 1 is installing the first mounting ring 12, the second mounting ring 13, the arc bracket 2, the airbag 21 and the barometer 22, the barometer 22 can be fixed by connecting the barometer 22 to the fixing part 32, thereby preventing the loose barometer 22 from falling and being damaged when the drill rod 1 is working inside the drill rod 1.

[0027] In some technical solutions, positioning rings 31 are fixedly installed on both sides of each group of airbags 21, and positioning holes are opened on both sides of each group of positioning rings 31. Positioning bolts are threadedly installed in the two corresponding groups of positioning holes, so that the airbags 21 can be positioned on the drill rod 1.

[0028] In this technical solution, each group of airbags 21 can be fixed by the positioning bolts installed through the positioning ring 31, ensuring that each group of airbags 21 is firmly positioned on the outer wall of the drill pipe 1 and distributed inside the arc-shaped bracket 2.

[0029] In some technical solutions, the outer walls of each set of first mounting rings 12 and second mounting rings 13 are provided with multiple sets of equidistantly distributed connecting holes, and each set of connecting holes is threadedly installed with connecting bolts 3, so that the first mounting rings 12 and second mounting rings 13 can be positioned on the drill pipe 1.

[0030] In this technical solution, multiple groups of first mounting rings 12 and second mounting rings 13 can be firmly fixed to the outer wall of the drill pipe 1 through the connecting bolts 3 installed with threads in each group of connecting holes, and the arc frame between the first mounting rings 12 and the second mounting rings 13 can be fixed.

[0031] When a drilling righting device for geological exploration is used, it should be noted that the utility model is a drilling righting device for geological exploration, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0032] When in use, firstly, by respectively fixing the first mounting ring 12 and the second mounting ring 13 on both sides of the middle of each group of drill rods 1, and cooperating with the multiple groups of equally spaced arc-shaped brackets 2 installed between each group of the first mounting rings 12 and the second mounting rings 13, the drill rod 1 can be supported so that the drill rod 1 is located in the middle of the borehole 11, so as to prevent the drill rod 1 from always being attached to the inner wall of the borehole 11, which may easily cause the drill rod 1 to bend. At the same time, the external air pump is connected to the airbag 21 in the straightening support mechanism, and the airbag 21 inside the multiple groups of arc-shaped brackets 2 is slowly inflated. After the airbag 21 is continuously expanded, the middle part of the multiple groups of arc-shaped brackets 2 can be effectively supported, which not only further effectively straightens the drill rod 1, but also effectively straightens the drill rod 1. At the same time, an air outlet pipe 23 is installed on the other side of the airbag 21, and a solenoid valve 24 is fixedly installed on the other end of the air outlet pipe 23. A pressure gauge 22 is installed on one side of the airbag 21 to detect the internal air pressure of the airbag 21 at all times. When the internal air pressure of the airbag 21 reaches the set value of the pressure gauge 22, a signal will be transmitted to the control processor to control the solenoid valve 24 at the port of the air outlet pipe 23, which not only discharges the internal gas of the airbag 21 and protects the airbag 21, but also the control processor that receives the signal will synchronously transmit the signal to the operator's central control computer to warn the operator that the drill rod 1 is squeezed by the mountain.
