[0002] With the progress of technology and the increasing demand for clean energy, geothermal energy, as a sustainable and environmentally friendly form of energy, is receiving more and more attention. The development and utilization of geothermal energy rely on efficient drilling technologies to ensure safe and economical access to underground heat energy resources. In this field, drilling tools have become indispensable tools in geothermal well drilling due to their high hardness, wear resistance, and corrosion resistance.

[0003] For example, the patent No. CN217632251U discloses a drilling device for geothermal exploration, which includes a bottom plate. Support columns are installed at the four corners of the bottom of the bottom plate. Moving wheels are installed at the bottom of the support columns. A fixing mechanism is arranged on the support columns. Two support sliding rods are vertically installed at the rear end of the top of the bottom plate. The top of the two support sliding rods is jointly connected with a mounting plate. A first motor is installed on the top of the mounting plate. The output end of the first motor penetrates through the mounting plate and is connected with a lead screw. The bottom end of the lead screw is rotatably connected with the bottom plate. The lead screw is arranged between the two support sliding rods. A moving plate is threadedly connected to the lead screw. The moving plate is slidably sleeved on the two support sliding rods. The utility model can firmly fix the drilling device, avoid the drill bit from deflecting during the drilling process, can cool down the drill bit, and improve the service life of the drill bit.

However, the drill bit cooling structure provided by this device cannot comprehensively clean the surface of the drill bit. If not cleaned in time, these substances will form an abrasive layer on the surface of the drill bit, exacerbate the wear of the drill bit, and thus reduce its service life. Summary of the Utility Model

It solves the problem that during deep hole drilling, the drill bit will be subjected to great pressure and friction, which will cause a large amount of rock dust and metal debris to accumulate on the surface of the drill bit. The drill bit cooling structure set by this device cannot comprehensively clean the surface of the drill bit. If not cleaned in time, these substances will form an abrasive layer on the surface of the drill bit, exacerbating the wear of the drill bit and thus reducing its service life.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: An auxiliary structure for a drilling tool used in a geothermal well, including a bottom plate, moving wheels, and a main drilling tool body.

The downward movement of the connecting plate 71 can drive the top plate 63, the connecting rod 62 and the spray head 4 to move downward. When the spray head 4 moves to both sides of the drill bit, turn off the double-headed motor 11, and then start the water pump 14 through the control panel 15 to inject water into the water tank 13, so that the water can be conveyed to the inside of the spray head 4 through the communication pipe 5 and sprayed to wash the surface of the drill bit.

[0038] In summary: For the auxiliary structure of a geothermal well drilling tool, by setting the spray head 4 and the communication pipe 5, after connecting the communication pipe 5 to an external water source and moving the spray head 4 to both sides of the drill bit, the surface of the drill bit can be washed and cleaned, solving the problem that during deep hole drilling, the drill head will be subjected to great pressure and friction, which will cause a large amount of rock dust and metal debris to accumulate on the surface of the drill head. The drill head cooling structure set by this device cannot comprehensively clean the surface of the drill head. If not cleaned in time, these substances will form an abrasive layer on the surface of the drill head, exacerbating the wear of the drill head and thus reducing its service life.
