[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown in the figure, this embodiment provides a safety protection system for drilling equipment.

[0026] A safety protection system for drilling equipment includes a fixed frame 1, on which multiple hydraulic telescopic rods 2 are fixedly installed. Multiple hydraulic tanks 17 are symmetrically fixedly installed on the top surface of the fixed frame 1. A hydraulic pump 18 connected to the hydraulic telescopic rods 2 is fixedly installed on one side of each hydraulic tank 17. A fixed plate 29 is fixedly installed on the output end of the multiple hydraulic telescopic rods 2. A first motor 3 is fixedly installed on the fixed plate 29. A drill rod 4 extending below the fixed plate 29 is fixedly installed on the output end of the first motor 3. A drill bit 5 is fixedly installed at the bottom of the drill rod 4. A gas detection mechanism 6 is provided on the drill rod 4. The gas detection mechanism 6 includes an installation groove 7 opened inside the drill rod 4. A wireless pressure sensor 8 is installed inside the installation groove 7. One end of the wireless pressure sensor 8 is attached to the bottom end of the drill bit 5. An installation frame 9 is fixedly installed on the top of the fixed frame 1. A wireless conversion terminal 10 is installed inside the installation frame 9.

[0027] By setting up the gas detection mechanism 6, the gas pressure inside the borehole can be detected in real time. A wireless pressure sensor 8 is installed after the connection of the drill bit 5. The wireless pressure sensor 8 detects the gas pressure inside the borehole. Since the wireless pressure sensor 8, the wireless conversion terminal 10, the first motor 3, the hydraulic telescopic rod 2 and the hydraulic pump 18 are connected by wires, when the gas pressure exceeds the limit, it is detected by the wireless pressure sensor 8. The wireless pressure sensor 8 transmits the signal to the wireless conversion terminal 10 set on the outside of the equipment, so that the wireless conversion terminal 10 can control the switch to stop the operation of the first motor 3, the hydraulic pump 18 and the hydraulic telescopic rod 2, so that the drill rod 4 and the drill bit 5 can run, avoiding the phenomenon of the drill getting stuck at the nozzle and preventing accidents.

[0028] In this embodiment, as Figures 1-5 As shown, a mounting plate 11 is fixedly installed on the wireless pressure sensor 8. The mounting plate 11 is fixedly connected to the first motor 3 by multiple bolts 12. A support plate 13 is installed on the mounting frame 9 and located at the bottom of the wireless conversion terminal 10. The support plate 13 is connected to the mounting frame 9 by multiple shock absorbers 14. An alarm 15 is fixedly installed on one side of the mounting bracket 1. An operation display screen 16 is fixedly installed on the mounting bracket 1 below the alarm 15. The wireless pressure sensor 8, hydraulic telescopic rod 2, first motor 3, hydraulic pump 18, wireless conversion terminal 10, alarm 15 and operation display screen 16 are all electrically connected by wires.

[0029] The mounting plate 11 and bolts 12 not only securely mount the wireless pressure sensor 8 in the mounting slot 7, improving stability, but also allow for easy disassembly and replacement in case of damage. The support plate 13 and shock absorber 14 provide shock absorption for the wireless conversion terminal 10, preventing damage caused by vibrations during drilling. The alarm 15 and operation display screen 16 serve as warnings; when the wireless pressure sensor 8 detects excessive gas pressure, the wireless conversion terminal 10 can... The signal transmitted by the linear pressure sensor 8 is sent to the alarm 15, causing the alarm 15 to sound to alert the staff. At the same time, the operation display screen 16 can also display the values ​​for the staff to see. Since the wireless pressure sensor 8, hydraulic telescopic rod 2, first motor 3, hydraulic pump 18, wireless conversion terminal 10, alarm 15 and operation display screen 16 are all electrically connected by wires, when a fault is detected, the wireless pressure sensor 8 and wireless terminal converter 10 can automatically control the start and stop of the hydraulic telescopic rod 2 and the first motor 3, and can also control the alarm 15 to start the alarm.

[0030] In this embodiment, as Figures 1-5 As shown, fixing blocks 19 are fixedly installed on both sides of the bottom of the fixing frame 1. A second motor 20 is fixedly installed on the top of the fixing block 19. A screw 21 fixedly connected to the output end of the second motor 20 is movably installed inside the fixing block 19. A movable block 22 connected by a thread is provided on the screw 21. A support frame 23 penetrating the bottom of the fixing block 19 is fixedly installed at the bottom of the movable block 22. A plug rod 24 is fixedly installed at the bottom of the support frame 23. A protective frame 25 fixedly installed on the fixing frame 1 is provided on the outside of the alarm 15 and the operation display screen 16. A movable door 26 is movably installed on the protective frame 25 by a hinge. Multiple sound outlets 27 are opened on the movable door 26. A viewing window 28 installed on the movable door 26 is provided below the wireless conversion terminal 10.

[0031] The fixed frame 1 is stably supported by the fixed block 19, the second motor 20, the screw 21, the movable block 22, the support frame 23, and the insertion rod 24. After the fixed frame 1 is placed, the two second motors 20 are started synchronously by the operation display screen 16, which drives the screw 21 to rotate. The rotation of the screw 21 drives the movable block 22, which pushes the support frame 23 to lower the insertion rod 24. The insertion rod 24 is inserted into the ground to provide balanced support for the fixed frame 1 and prevent tilting. The protective frame 25 and the movable door 26 protect the alarm 15 and the operation display screen 16 from damage caused by collisions. The sound outlet 27 and the viewing window 28 allow the sound emitted by the alarm 15 to be transmitted outwards, while the viewing window 28 allows the operation display screen 16 to be viewed directly through the movable door 26.

[0032] In this embodiment, as Figures 1-5 As shown in the figure, the working process of the safety protection system for drilling equipment provided in this embodiment is as follows:

[0033] Step 1: Place the entire fixing frame 1 at the hole opening, push the push rod movable block 22 to make the support screw 21 rotate and extend into the ground for fixed support, then start the first motor 3 to drive the drill rod 4 to rotate, start the hydraulic telescopic rod to drive the drill rod 4 to descend, so that the drill bit 5 drills into the hole;

[0034] Step 2: During the drilling process, the wireless pressure sensor 8 detects the gas pressure. When the wireless pressure sensor 8 detects that the gas pressure exceeds the limit, it transmits a signal to the wireless conversion terminal 10. At the same time, the wireless conversion terminal 10 transmits signals to the alarm 15 and the operation display screen 16 and controls the switch to stop the equipment. The staff who receive the warning from the alarm 15 can view the value through the operation display screen 16 and adjust the equipment.
