Description

Technical Field

[0001] This utility model relates to the technical field of geological exploration, and in particular to a new energy core drilling rig. Background Technology

[0002] A core drilling rig is a type of core drilling equipment primarily used for the general survey and exploration of metallic or non-metallic solid minerals. It can also be used for engineering geological surveys, hydrogeological investigations, oil and gas field exploration, and water well drilling.

[0003] Traditional core drilling rigs have several drawbacks in terms of environmental and energy utilization. First, since traditional core drilling rigs are usually driven by diesel engines, they inevitably emit exhaust gases during operation, polluting the atmosphere and affecting air quality. In addition, the operation of diesel engines also generates high noise levels, causing noise pollution to operators and the surrounding environment. Long-term exposure to high noise levels may have adverse effects on hearing, the nervous system, the cardiovascular system, and the immune system.

[0004] Secondly, traditional core drilling rigs are heavily reliant on oil resources, which are non-renewable. Long-term dependence on oil not only increases operating costs but also exacerbates resource depletion, hindering sustainable development. Furthermore, traditional core drilling rigs have low energy conversion efficiency, resulting in low energy utilization and further increasing operating costs and environmental burden.

[0005] In summary, traditional core drilling rigs have significant limitations in terms of environmental protection, energy utilization, and operating costs, and urgently need improvement. Utility Model Content

Rather, these embodiments are provided to make the disclosure of the new energy core drilling rig more thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the new energy core drilling rig is for the purpose of describing particular embodiments only and is not intended to be limiting of the 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, in one embodiment, the new energy core drilling rig 10 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 for driving the motor 110. The spindle system 200 includes a rotary head 210 for driving the drill rod and a core tube 220 for mounting on the drill rod. The drilling tower system 300 is used for hoisting the drill rod. The transmission system 400 connects the power system 100, the spindle system 200, and the drilling tower system 300, respectively, and the power system 100 drives the spindle system 200 and the drilling tower system 300 to move through the transmission system 400. The control system 500 is electrically connected to the power system 100 and the transmission system 400 to control them. The sensing system 600 includes sensors for sensing the working state 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, which can be housed within the motor compartment 112. Specifically, in one embodiment, the power input voltage of the permanent magnet synchronous motor can be 480–700VDC, the low-voltage control power supply can be 12V, and the control modes can include position, speed, and torque modes. The permanent magnet synchronous motor of the new energy core drilling rig 10 can maintain a constant speed on straight roads and on inclines and declines. The permanent magnet synchronous motor can also have multi-faceted protection functions such as position error, overcurrent, overvoltage or undervoltage, overtemperature, and output short circuit overload. In one embodiment, the permanent magnet synchronous motor can also have a stall protection function. When the output current exceeds a certain value, or when the motor 110 cannot rotate for more than 5 seconds, the motor 110 driver will stop the motor 110 and report a stall fault on the bus.

[0024] In one embodiment, the power system 100 may further include a housing 130. The new energy core drilling rig 10 also includes 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 multiple 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 within a housing cover 130, and the other part of the battery boxes 122 are located within a frame 700. The battery boxes 122 are described in detail below. Figure 3 and Figure 4Furthermore, in one embodiment, the battery box 122 may include lithium iron phosphate square batteries and a battery management system sampling module, which is used to sample voltage, temperature, and insulation. In this embodiment, there are four battery boxes 122, using a total of 192 228Ah lithium iron phosphate square batteries. In one embodiment, the high-voltage junction box 124 may house the battery management system host module, relays, fuses, and other components. In one embodiment, the lithium iron phosphate square battery cell is model LFP228, with a rated energy of approximately 140.9 kWh, a usable capacity 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 voltage conversion. The DC / DC converter 126 may be disposed within a housing 130.

[0027] See Figure 1 In one embodiment, the control system 500 may include an electrical control box 510, a controller disposed within the electrical control box 510, an LED display 520 disposed on the electrical control box 510, and an operating console 530. Both the LED display 520 and the operating console 530 are electrically connected to the controller. The sensors in the sensing system 600 may include one or more of a speed sensor 610, a displacement sensor 620, a level 630, a load cell 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 equipment stability, and achieve data standardization and procedural operation. It optimizes multiple functions such as overall machine leveling and inductive control to improve operational accuracy and reliability.

[0028] Specifically, the speed sensor 610 can be installed on the rotary head 210 to sense the rotational speed of the drill rod. The LED display 520 is electrically connected to the speed sensor 610 to display the rotational speed of the drill rod. Traditional core drilling rigs typically rely on the operator's experience to judge the head rotation speed, while the new energy core drilling rig 10 adds a data-driven display of the rotational speed, allowing the operator to intuitively monitor the head rotation speed and make precise adjustments as needed. This data-driven display not only optimizes drill bit performance but also improves the accuracy and procedural level of the drilling operation.

[0029] A displacement sensor 620 is mounted on the transmission system 400 to sense the travel distance of the drill rod. An LED display 520 is electrically connected to the displacement sensor 620 to display the travel distance of the drill rod. Traditional core drilling rigs rely on operator experience to estimate drilling depth, making it difficult to accurately measure the drilling depth and determine whether drilling will proceed smoothly when encountering hard rock formations. The newly added displacement sensor 620 can visually display the drilling depth and accumulate the total depth, providing greater accuracy and convenience for construction.

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

[0031] A load cell 640 is installed on the drilling rig system 300 to sense the load on the drilling rig system 300. An LED display 520 is electrically connected to the load cell 640 to display the load on the drilling rig system 300. In traditional core drilling rigs, operators cannot visually identify the weight of objects during lifting, which may lead to mechanical overload and safety hazards. The new energy core drilling rig 10's newly added lifting load display function can measure the weight of objects in real time during lifting, helping operators effectively prevent overload accidents, improve construction safety, and ensure work quality.

[0032] The safety sensor 650 is used to issue a warning when the new energy core drilling rig 10 is displaced. In one embodiment, the safety sensor 650 can be a buzzer warning device, which can effectively indicate the backward movement of the equipment, prevent safety hazards caused by backward movement, improve operational safety, and ensure the smooth progress of construction.

[0033] The aforementioned new energy core drilling rig 10 uses a power system 100 that drives a motor 110 via a battery pack 120. The motor 110 then drives the spindle system 200 and the drilling tower system 300 through a transmission system 400, thereby enabling the new energy core drilling rig 10 to operate. Because the aforementioned 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, driven by new energy sources, the new energy core drilling rig 10 does not produce diesel exhaust emissions during operation, avoiding atmospheric pollution and helping to maintain clean air, achieving near-zero pollution. Furthermore, the rig operates with low noise, effectively reducing noise pollution to operators and the surrounding environment, minimizing potential harm to hearing, the nervous system, the cardiovascular system, and the immune system, and improving operational comfort.

[0035] Secondly, the new energy core drilling rig 10 reduces dependence on oil resources and improves the flexibility of energy utilization. Its power supply can include battery power, and the electricity required for battery charging can be obtained through conversion from various energy sources such as coal, natural gas, hydropower, solar energy, and wind power. Especially when charging at night, it avoids peak electricity consumption, helps balance the grid load, reduces operating costs, and improves economic efficiency.

[0036] In summary, the new energy core drilling rig 10 not only avoids exhaust emissions and significantly reduces noise, but also reduces operating costs and energy consumption, making it more in line with the needs of sustainable development.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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 embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
