Needless to say, the content protected by the present utility model does not involve improvements to software and methods.

[0033] The working principle of the large-diameter geothermal drilling support device provided by the utility model is as follows:

[0034] When in use, the whole is installed. According to the diameter and length of the drill rod on the geothermal drilling equipment, the motor 303 is started by the controller to drive the screw rod 301 to rotate. Under the limiting effect of the limiting rod on the mounting block 302, the screw rod 301 drives the two mounting blocks 302 to move relatively, thereby adjusting the use position of the two support mechanisms 4. At this time, the positions of the two support mechanisms 4 are such that the drill rod can pass through the middle position of the two support mechanisms 4, and the support ring 402 on the support mechanism 4 contacts the outer wall of the drill rod, thereby performing certain support and limiting on the drill rod during use, thereby improving the stability of the drill rod during use;

[0035] When the drill rod moves downward in the process of drilling, the drill rod and the support ring 402 come into contact. If the drill rod reaches a certain position, the drill rod will squeeze the support ring 402. When the support ring 402 is squeezed, the support ring 402 drives the retaining frame 405 to squeeze the spring 406, and drives the guide rod 404 to move. When the drill rod exceeds the corresponding displacement range, the guide rod 404 drives the trigger block 502 and the trigger button 504 to contact and squeeze, thereby triggering the alarm 503 to alarm. At this time, the drill rod can be well supported and limited by the interaction between the mounting ring 401 and the support ring 402, and the staff can timely understand the excessive deviation of the drill rod, so as to make timely adjustments according to the actual operation conditions, thereby improving the safety during the drilling operation.

[0036] At the same time, in the process of drilling a hole on the geothermal surface, the telescopic rod 603 is started to drive the nozzle 605 close to the drill rod, the water inlet end of the water pump 601 is connected to the corresponding water source pipeline, and the water pump 601 is started. Water enters the diversion pipe 604 through the bellows 602, and then is sprayed onto the drill rod through the nozzle 605, thereby lubricating the drill rod and improving the drilling efficiency of the drill rod.

[0037] Compared with the related art, the geothermal large-diameter drilling support device provided by the utility model has the following beneficial effects:

[0038] The utility model provides a large-aperture drilling support device for geothermal use, which is formed by a support column 1, a mounting frame 2, a moving mechanism 3, a supporting mechanism 4, a monitoring mechanism 5 and a lubricating mechanism 6. The large-aperture drilling support device for geothermal use can support the drill rod in the process of drilling a hole on the geothermal surface, improve the stability of the drill rod during operation, and monitor the displacement of the drill rod. When the displacement exceeds the safe displacement range, an alarm can be given in time, so that the staff can timely understand the excessive displacement of the drill rod, so as to make timely adjustments according to the actual operation conditions, thereby improving the safety during the drilling operation.

[0039] The moving mechanism 3 can drive the two supporting mechanisms 4 to move relative to each other to support the drill rod, thereby improving the stability of the drill rod. The monitoring mechanism 5 can promptly give an alarm when the drill rod is excessively displaced, so that the staff can promptly understand the situation of excessive displacement of the drill rod, so as to make timely adjustments according to the actual working conditions, thereby improving the safety during the drilling operation.
