The drawings illustrate a preferred embodiment of the new energy core drilling rig. However, the new energy core drilling rig can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the new energy core drilling rig.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the new energy core drilling rig are intended solely for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 As shown, a new energy core drilling rig 10 in one embodiment includes a power system 100, a spindle system 200, a drilling tower system 300, a transmission system 400, a control system 500, and a sensing system 600. The power system 100 includes a motor 110 and a battery pack 120 that drives the motor 110. The spindle system 200 includes a rotator 210 for rotating the drill pipe and a core barrel 220 for being mounted on the drill pipe. The drilling tower system 300 is used to hoist the drill pipe. The transmission system 400 is connected to the power system 100, the spindle system 200, and the drilling tower system 300. The power system 100 drives the spindle system 200 and the drilling tower system 300 through the transmission system 400. The control system 500 is electrically connected to the power system 100 and the transmission system 400 to control the power system 100 and the transmission system 400. The sensing system 600 includes sensors for sensing the operating status of the new energy core drilling rig 10, and the sensors are electrically connected to the control system 500.

[0023] In one embodiment, the motor 110 is a permanent magnet synchronous motor and can be arranged in the motor compartment 112. Specifically, in one embodiment, the power input voltage of the permanent magnet synchronous motor can be 480-700 VDC, the low-voltage control power supply can be 12V, and the control mode can include position, speed, and torque modes. The permanent magnet synchronous motor of the new energy core drilling rig 10 can be controlled to run at a constant speed when on a straight road or up and down slopes. The permanent magnet synchronous motor can also have multi-faceted protection functions such as position error, overcurrent, overvoltage or undervoltage, overtemperature, output short circuit and overload. In one embodiment, the permanent magnet synchronous motor can also have a stall protection function. When the output current is greater than a certain value, or when the motor 110 cannot rotate for more than 5 seconds, the motor 110 driver will stop the motor 110 from running, and the bus will report a stall fault.

[0024] In one embodiment, the power system 100 may further include a housing 130 . The new energy core drilling rig 10 may further include a frame 700 located at the bottom of the housing 130 , the drilling tower system 300 , and the transmission system 400 .

[0025] See also Figure 2 The battery pack 120 may include a plurality of battery boxes 122 and a high voltage junction box 124, wherein the high voltage junction box 124 and part of the battery boxes 122 are located in the housing 130, and the other part of the battery boxes 122 are located in the rack 700. Figure 3 and Figure 4. Further, in one embodiment, the battery box 122 may include lithium iron phosphate square batteries and a battery management system sampling module, and the battery management system sampling module is used to sample voltage, temperature and insulation. In this embodiment, the number of battery boxes 122 is four, and a total of 192 228Ah lithium iron phosphate square batteries are used. In one embodiment, the high-voltage junction box 124 may be installed with battery management system host modules, relays, fuses and other sub-components. In one embodiment, the single cell model of the lithium iron phosphate square battery is LFP228, with a rated energy of approximately 140.9KWh, an available power of 5%~100% SOC, a charging conversion efficiency of up to 90%, a rated voltage of approximately 618.12V, an operating voltage range of 480V-700.8V, and a rated capacity of approximately 228Ah.

[0026] In one embodiment, the battery pack 120 may further include a DC / DC converter 126 for converting voltage. The DC / DC converter 126 may be disposed within the housing 130 .

[0027] See also Figure 1 In one embodiment, the control system 500 may include an electric control box 510, a controller disposed in the electric control box 510, an LED display 520 disposed on the electric control box 510, and an operating table 530. The LED display 520 and the operating table 530 are both electrically connected to the controller. The sensors of the sensing system 600 may include one or more of a speed sensor 610, a displacement sensor 620, a level 630, a load-bearing sensor 640, and a safety sensor 650. The sensing system 600 can help the new energy core drilling rig 10 avoid the technical defects of traditional core drilling rigs, improve the stability of the equipment, and achieve data standardization and procedural operation. Multiple functions such as the whole machine horizontal adjustment and electric induction control have been optimized to improve operation accuracy and reliability.

[0028] Specifically, a rotation speed sensor 610 can be installed on the rotator 210 to sense the rotation speed of the drill pipe. An LED display 520 is electrically connected to the rotation speed sensor 610 to display the rotation speed of the drill pipe. Traditional core drills typically rely on the operator's experience to determine the drill head rotation speed. The new energy core drill rig 10 incorporates a digital display of the rotation speed, allowing the operator to intuitively monitor the drill head rotation speed and make precise adjustments based on demand. This digital display not only optimizes drilling tool performance but also improves the accuracy and level of proceduralization of construction.

[0029] Displacement sensor 620 is mounted on transmission system 400 and is used to sense the travel distance of the drill rod. LED display 520 is electrically connected to displacement sensor 620 to display the travel distance of the drill rod. Traditional core drills rely on the operator's experience to estimate the depth during drilling, making it difficult to accurately measure the depth and unable to accurately determine successful drilling in hard rock formations. The newly added displacement sensor 620 visually displays the drilling depth and accumulates the total depth, providing greater accuracy and convenience during construction.

[0030] The level 630 is used to sense the levelness of the new energy core drill 10. In one embodiment, the level 630 can be mounted on the motor compartment 112. The LED display 520 is electrically connected to the level 630 to display the levelness of the new energy core drill 10. The newly added level 630 on the new energy core drill 10 can intuitively display verticality and accurately indicate balance offset, making the data more scientific, reducing reliance on operator experience, and thus improving construction accuracy.

[0031] A load sensor 640 is mounted on the drilling tower system 300 and is used to sense the load of the drilling tower system 300. An LED display 520 is electrically connected to the load sensor 640 to display the load of the drilling tower system 300. When lifting objects with traditional core drilling rigs, operators cannot visually identify the weight, which can lead to mechanical overload and create safety hazards. The new energy core drilling rig 10 features a new load display function that measures the weight of objects in real time during the lifting process, helping operators effectively prevent overloading accidents, improve construction safety, and ensure work quality.

[0032] The safety sensor 650 is used to issue an alarm when the new energy core drilling rig 10 moves. In one embodiment, the safety sensor 650 can be a buzzer alarm device that can effectively indicate the equipment's backward movement status, prevent safety hazards caused by backward movement, improve operational safety, and ensure smooth construction.

[0033] In the new energy core drilling rig 10, the power system 100 drives the motor 110 via the battery pack 120. The motor 110 drives the spindle system 200 and the derrick system 300 via the transmission system 400 to operate the new energy core drilling rig 10. Because the new energy core drilling rig 10 uses electricity as its power source, it has significant advantages in terms of environmental protection and energy utilization.

[0034] First, because it uses renewable energy, the new energy core drill rig 10 produces no diesel exhaust during operation, thus avoiding atmospheric pollution and helping to maintain clean air, achieving near-zero pollution. Furthermore, the drill rig operates with low noise levels, effectively reducing noise pollution to operators and the surrounding environment, minimizing potential noise damage to the auditory, nervous, cardiovascular, and immune systems, and enhancing operator comfort.

[0035] Secondly, the new energy core drilling rig 10 reduces dependence on oil resources and increases energy flexibility. Its energy supply can include battery power, and the electricity required to charge the batteries can be converted from various energy sources, such as coal, natural gas, hydropower, solar power, and wind power. Especially during nighttime charging, peak power consumption can be avoided, helping to balance the load on the power grid, reduce operating costs, and improve economic efficiency.

[0036] In summary, the new energy core drilling rig 10 can not only avoid exhaust gas emissions and significantly reduce noise, but also reduce operating costs and energy consumption, and is more in line with sustainable development needs.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
