[0002] Geothermal exploration drilling equipment is mainly used to explore and develop thermal energy resources hidden underground. This type of equipment usually uses advanced drilling and well-drilling technology to obtain information such as underground temperature, heat flux density, and geological structure.

[0003] Existing geothermal exploration drilling equipment lacks a dedicated self-cleaning device for the drilling device, and workers need to manually clean it after drilling is completed, which slows down work efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides a geothermal exploration drilling device, which overcomes the shortcomings of the prior art and aims to solve the problem that the existing geothermal exploration drilling equipment lacks a dedicated self-cleaning device for the drilling device, and that the staff needs to manually clean it after drilling is completed, which delays work efficiency.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A drilling equipment for geothermal exploration, comprising a drilling tower, a lifting motor is installed above the interior of the drilling tower, a screw is installed at the output end of the lifting motor, a lifting platform is rotatably connected to the outer wall of the screw, a drilling motor is fixedly installed below the lifting platform, a rotating connecting piece is fixedly connected to the output end of the drilling motor, a drill rod is installed below the rotating connecting piece, two groups of bases are installed below the interior of the drilling tower, cleaning motors are installed inside the two groups of bases, water tanks and cleaning racks are arranged above the two groups of bases, the cleaning racks are located on the inner sides of the two groups of water tanks, openings corresponding to the drill rods are opened inside the cleaning racks, multiple groups of nozzles are installed above the cleaning racks, and the nozzles are arranged toward the drill rods, a water pump is installed on one side of the water tank, a water pipe is installed at the output end of the water pump, the water pump extends to the top of the cleaning rack and is connected to the multiple groups of nozzles, and cleaning brushes are fixedly installed at the output ends of the two groups of cleaning motors.

[0006] By adopting the above technical scheme, a lifting motor is set to drive the rotation of the screw rod, so that the lifting platform can move up and down, thereby driving the drilling motor to move up and down, and the drilling motor is set to drive the rotation of the drill rod to realize drilling on the ground. After the drilling is completed, the drill rod can be lifted and the cleaning brush can be driven by the cleaning motor to clean the drill rod. The cleaning water is brought from the inside of the water tank to the nozzle on the cleaning frame through the water pump and sprayed out by the nozzle. The cleaning brush and the nozzle cooperate with each other to complete the cleaning of the drill rod. This setting can effectively reduce the frequency of manual cleaning, improve the working efficiency of the equipment, ensure that each drilling sampling sample will not be contaminated by drill bit residue, facilitate the staff's analysis of the drilling samples, and the sprayed water can also accelerate the heat dissipation, so that the drill rod cools faster, thereby improving the working efficiency of the device.

[0009] As a preferred technical solution of the present application, two groups of booster rods are installed on both sides of the interior of the drilling tower, and the outer walls of the two groups of booster rods are sleeved on both sides of the lifting platform.

[0014] By adopting the above technical solution and setting a multi-wing cutting structure, the cutting area can be effectively increased and the drilling efficiency can be effectively improved.

[0015] As a preferred technical solution of the present application, a transparent scale observation window is installed on one side of the two groups of water tanks.

[0016] By adopting the above technical solution and providing a transparent scale observation window, the staff can better observe the water level inside the water tank, thereby avoiding the influence of insufficient water level on the cleaning of the drill rod.

[0017] Beneficial effects of this application:

[0018] 1. By setting a lifting motor, the screw can be driven to rotate, so that the lifting platform can move up and down, thereby driving the drilling motor to move up and down. By setting the drilling motor, the drill rod can be driven to rotate to realize drilling on the ground. After the drilling is completed, the drill rod can be lifted and the cleaning motor can be used to drive the cleaning brush to clean the drill rod. The cleaning water is brought from the inside of the water tank through the water pump to the nozzle on the cleaning rack and sprayed out by the nozzle. The cleaning brush and the nozzle cooperate with each other to complete the cleaning of the drill rod. This setting can effectively reduce the frequency of manual cleaning, improve the working efficiency of the equipment, ensure that each drilling sampling sample will not be contaminated by drill bit residues, facilitate the staff's analysis of drilling samples, and the sprayed water can also accelerate heat dissipation, so that the drill rod cools faster, and improves the working efficiency of the device.

[0019] 2. By setting up a micro cooling pump, the heat dissipation effect of the drill bit can be achieved by circulating the liquid inside the liquid cooling tube. After the liquid cooling tube absorbs heat at the top of the drill bit, it can discharge the heat through the drill rod. This setting avoids the waste of resources and ensures the heat dissipation efficiency. The device is relatively simple and will not affect the drilling process. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the drilling motor 401, the rotation of the drill rod 501 can be driven to realize the drilling of the ground. After the drilling is completed, the drill rod 501 can be lifted and driven by the cleaning motor 201 to drive the cleaning brush 701 to clean the drill rod 501.

After the drilling is completed, the drill rod 501 can be lifted and the cleaning brush 701 can be driven by the cleaning motor 201 to clean the drill rod 501. The cleaning water is brought from the inside of the water tank 6 to the nozzle on the cleaning frame 7 through the water pump 601 and sprayed out by the nozzle.
