[0001] The present disclosure relates to a mobile battery and / or a battery hybrid mobile power supply device for supplying power to one or more drill rigs.

Background Art

[0002] The drilling environment is harsh and includes drilling with continuous vibration and impact. An electric drill rig needs to be trammed or moved on track between multiple positions to avoid environmental risks, i.e., during rock blasting, the drill is kept away from the blasting zone and drilling continues at numerous different positions.

[0003] The current state of the art is a diesel hydraulic drive for a tethered mobile electric drill. Such a tethered mobile electric drill is connected to the power grid by an electric cable, for example, more than 300 meters (1000 feet) long. To move the drill over a long distance exceeding 300 - 400 meters, the plug of the drill needs to be unplugged and power supplied by, for example, a diesel hydraulic power unit for driving a hydraulic driven drill truck.

[0004] Alternatively, the drill rig is loaded onto a lowboy trailer and moved or dragged across the ground on steel skids. <​​​​​​​[Overview of the project]

[0007] This disclosure relates to a battery-powered mobile power supply and / or a diesel / hydrogen gas-electric hybrid mobile power supply for powering the drill rig's own system for long-distance travel. The battery / power supply can power the rig when needed and can be used with multiple electric rigs.

[0008] In one embodiment, a single mobile battery / power source can operate multiple electric drills.

[0009] Mobile battery / power solutions can utilize existing grid power for recharging and therefore can be a source of renewable energy.

[0010] The mobile battery power supply unit can be self-propelled or mounted inside a mobile trailer.

[0011] The autonomous, self-propelled power supply unit can be linked to the drill and automatically controlled by guidance from the drill.

[0012] The power supply unit can be a hybrid, using either a diesel engine or a hydrogen gas engine to supply power to the electric rig.

[0013] A detachable mobile power supply unit communicates with the drive assembly and is positioned to move the vehicle when the drive assembly is not operating.

[0014] The above overview and the following description of embodiments will be better understood when read in conjunction with the attached drawings. It should be understood that the illustrated embodiments are not limited to the exact arrangements and means shown. [Brief explanation of the drawing]

[0015] [Figure 1] This is a side view of the electric drill rig and mobile battery / power supply device of the present disclosure. [Figure 2] This is a perspective view of the mobile battery power supply device disclosed herein. [Figure 3] This is a block diagram of a mobile autonomous hybrid power supply unit. [Modes for carrying out the invention]

[0016] As shown in Figure 1, a mining vehicle 10, such as a rotary electric drill rig, includes a deck or carriage 12 and a mast 14 attached to a first end 16 of the carriage. As is well known, the mast 14 is movable between a horizontal stowed position and a vertical operating position, where mounted work equipment or drilling components can be operated. A cab 18 is also provided at the first end 16. The vehicle is powered by a drive assembly 20, which includes known components and is further described herein. The vehicle 10 includes other conventional components, which are not described further herein. Furthermore, other types of vehicles powered by the Mobile Battery and / or Battery Hybrid Mobile Power Supply are also conceivable, and it should be understood that this disclosure is not limited to mining vehicles.

[0017] As described above, in addition to the conventional drive assembly 20, the vehicle 10 can be powered using a battery-powered and / or diesel-electric hybrid mobile power supply unit 30 to power the drill rig's own systems for tramming or long-distance travel. For example, an internal combustion engine (ICE) 46 that uses diesel, an alternative fuel, and an alternative fuel containing hydrogen in an electric fuel cell that uses hydrogen as fuel, as an example.

[0018] As shown in Figure 1, the mobile power supply unit 30 can be detachably attached to the end 17 of the vehicle. For clarity, the power supply unit in Figure 1 is shown at the end of the drill's cable reel, but it does not need to be in that position during transit.

[0019] The mobile power supply unit 30 can be mounted on a trailer 32 that can be attached to the coupling section 34. Although shown as a trailer 32 attached to the deck 12, the mobile power supply unit 30 may be an autonomous, self-propelled power supply unit that is remotely operated by an autonomous or remote control system via a control system 50 located within the vehicle or in the mining environment.

[0020] The mobile power supply unit 30 can be detachably attached to the vehicle power supply unit via a cable 38. Therefore, the vehicle can be powered by the mobile power supply unit 30 when needed, and the mobile power supply unit 30 is detachable so that it can be used in multiple electric vehicles. Thus, one mobile power supply unit can, for example, power multiple electric drill rigs.

[0021] Referring to Figure 2, the mobile power supply unit 30 can be a battery power system in which multiple rechargeable batteries 38 are housed in an air-conditioned housing 40. The mobile power supply unit 30 can be operated by a DC-AC inverter including standard electrical components and a transformer.

[0022] Referring to Figure 3, the mobile power supply 30 can also be a hybrid using a diesel engine or a hydrogen engine 46 to supply power to the electric drive system. In this embodiment, the power supply will be provided by components such as a DC-AC inverter and conditioning, an AC generator to DC generator 42, and a control system 50.

[0023] The power supply can be placed at any position by the drilling rig. By using cameras, GPS, proximity sensors, obstacle and cable detection sensors, and mine maps, autonomous self-propelled and / or remotely controlled power supplies can be placed on either side of the drill and at any distance required for movement to avoid collisions with the drill and obstacles, for example during turning. Along with the aforementioned sensors, cable management software manages the cables to keep them in an appropriate position so as not to run over the cables. The power supply in Figure 1 is shown in a state at the cable reel end of the drill for clarity, but it does not need to be in that position during movement.

[0024] In summary, expensive batteries are only used when needed and are not attached to the drill when not in use. The space required by the battery on the drill is large, and the electric drill would become more expensive. In the battery solution, grid power that can be renewable energy is used for recharging. The mobile battery power supply can be self-propelled or designed to be mounted on a trailer. The autonomous self-propelled power supply can be interlocked with the drill to enable automatic steering and / or can use guidance from the drill.

[0025] Although the present embodiment has been described with respect to its particular aspects, many other variations, modifications, and other uses will be apparent to those skilled in the art. Therefore, it is preferred that the present embodiment be limited only by the appended claims and not by the specific disclosure of this specification.
