Description

[0001] A DRILL RIG

[0002] TECHNICAL FIELD

[0003] The present disclosure relates to a drill rig. It further relates to a method for cooling at least one component that generates heat and / or heating at least one component that requires heat on a drill rig.

[0004] BACKGROUND

[0005] Flushing medium may be used on for example blast hole drill rigs or exploration drill rigs, for flushing away chips or cuttings in bore holes. Chips or cuttings may be the material that is produced on drilling. The flushing medium may be a gas, a liquid or a combination of gas and liquid.

[0006] A drill rig may comprise a tank for storing a flushing medium which may be used for flushing. The flushing medium is used for flushing away chips or cuttings, and it may be used to suppress dust formations and to stabilize the borehole.

[0007] The flushing medium is conveyed via channels to a nozzle and the flushing medium is flushed through a nozzle into the bore hole. The flushing medium may be combined with another flushing medium before being flushed through the nozzle.

[0008] A drill rig comprises several components that need to be cooled. Such components may be electric, hydraulic, mechanical and / or pneumatic components. The cooling of the components may be performed with air, oil and / or water cooling wherein water is used in a closed system.

[0009] When electrifying drill rigs, there is a challenge to cool battery systems, hydraulic systems, fuel cells and electrical systems. Large, heavy and space requiring coolers are needed. Access to service and maintenance will require an expensive solution. Overcapacity in order to meet the cooling requirements during effect pikes, stability, for example, may be expensive. The electric system works at lower temperatures than a diesel motor which makes the temperature difference lower, i.e. it will be more demanding to cool an electric system. There is therefore a desire to improve the cooling of drill rigs comprising electric systems. Further, there is a desire to use components in a cold environment that may require components to be heated.

[0064] DETAILED DESCRIPTION

[0065] Drill rigs are becoming electrified in order to reduce the use of, for example, diesel engines. The use of electrified drill rigs reduces the impact on the environment and may further improve the environment for workers. A drill rig comprises several components, such as electric, hydraulic, mechanical, pneumatic components or fuel cells that may need to be cooled. When electrifying drill rigs, it may be challenging to cool components of the drill rig. Electric systems work at lower temperatures than a diesel motor and the temperature difference to the environment will be lower. This makes it more demanding to cool an electric system. Further, it may be difficult to use components, such as batteries for example, in a cold climate. The battery may need to be heated in order to be able to work, or at least work efficiently.

[0066] According to the disclosure a drill rig is provided comprising a flushing system that includes at least one nozzle to provide a first flushing medium and at least one flushing channel arranged to convey first flushing medium from at least one flushing medium storage means to the at least one nozzle. At least one flushing medium storage means may be arranged to store a first flushing medium. The flushing medium storage means may be comprised on the drill rig or a flushing medium storage means may be separate from the drill rig. The first flushing medium may be combined and mixed with a second flushing medium. The first flushing medium may comprise gas and / or liquid. Further, the first flushing medium may be a liquid that may be converted to a gas, for example when leaving the flushing medium storage means or leaving the nozzle. The second flushing medium may comprise gas and / or liquid to flush away chips or cuttings in bore holes. The gas used as second flushing medium may be compressed 15as air. Chips or cuttings may be the material that is produced on drilling. The first flushing medium may also be used to suppress dust formations and to stabilize the borehole. First flushing medium may be used as a second flushing medium.

[0067] A drill rig 10 is shown in Figure 17, which will also be referred to below in the text. The drill rig 10 of the embodiment of Figure 17 comprises a component 4 which generates heat and a component 5 that requires heat. Two components are shown, but several components may be used or only one component may be used. Figure 17 describes an example of a drill rig 10. A tank 1 is comprised on the drill rig 10 and is arranged for storing a first flushing medium. In some examples of embodiments herein, the tank 1 is comprised, such as located, separate from the drill rig 10, and may then be a tank, a reservoir, a basin, pool, a dam or a pond. The drill rig 10 comprises a flushing system (not shown in figure 17), wherein the flushing system comprises a nozzle 32 to provide first flushing medium and a flushing channel (not shown in figure 17). A tank 1 is comprised on the drill rig 10. When workers start a work shift with the blast hole drill rig 10, the tank 1 of the blast hole drill rig 10 is filled with a first flushing medium. In the area of the use of the blast hole drill rig, there is usually not possible to refill the tank 1 or continuously provide the blast hole drill rig 10 with first flushing medium to be used for flushing bore holes. The blast hole drill rig 10 will be travelled or transported to the work area. During the work shift, the first flushing medium will be used for flushing or it may be used for dust suppressing and to stabilize the borehole, and the first flushing medium will be sprayed or flushed through the nozzle 32. The first flushing medium may also be provided in the nozzle 32 together with a second flushing medium. When the first flushing medium is sprayed through the nozzle 32 and the first flushing medium is conveyed from the tank 1 to the nozzle 32, for example, the first flushing medium may cool a component 4 that generates heat or, for example, the first flushing medium may heat a component 5 that requires heat. The flushing system may enhance the cooling of components, that generate heat, of the drill rig 10. Alternatively, the flushing system may enhance the heating of components, that require heat, of the blast hole drill rig 10. The first flushing medium in the tank 1 may be consumed during the work shift. The blast hole drill rig 10 may be transported to a location, where the tank 1 may be refilled. Alternatively, a supply vehicle may be transported to the blast hole drill rig 10 for refilling the at least one tank 1. As a further alternative, the at least one tank 1 may be refilled when starting the next work shift. A tank 1 has been disclosed in this embodiment, but in other examples of embodiments, a flushing medium storage means may be a reservoir, a basin, a pool, a dam or a pond.

[0068] For an exploration drill rig, a flushing medium storage means may for example be comprised separate from the drill rig. An flushing medium storage means separate from a drill rig may be a tank, a reservoir, a basin, a pool, a dam or a pond for example. The first flushing medium will be used in the same manner as disclosed above for the blast hole drill rig. For an exploration drill rig, it may then be possible to transport a reservoir to the drill rig and to use the medium of the reservoir as a first flushing medium as disclosed above.

[0069] Several embodiments of the disclosure comprising a flushing system are disclosed in Figures 1-16, which will be described below. The flushing system in the figures are schematic and the embodiments may also include for example additional components and additional channels.

[0074] The drill rig 10 may be a blast hole drill rig or the drill rig may be an exploration drill rig.

[0075] At least a part of the heat generated by the at least one component 4 the generates heat may be transferred to the first flushing medium or to the closed circuit channel medium.

[0076] Several alternatives of components which generate heat and components that require heat may be cooled and / or heated according to the disclosure. Several channels may be arranged for cooling and heating components on a drill rig. Some embodiments of the disclosure will be described below. The drawings are schematical. A flushing system including a flushing channel 3 and a nozzle 2 is disclosed in Figures 1 to 16. A flushing medium storage means 1 is disclosed. The flushing medium storage means 1 may be comprised, such as located, on the drill rig 10 or separate from the drill rig 10. Further, the embodiments may comprise at least one component 4, 5, additional channels, such as at least one optional circulating channel 8, 9 or at least one optional closed circuit channels 6, 7. The drill rig 10 is not shown in those figures. A bore hole 15 is illustrated in the figures.

[0077] Figure 1 discloses a flushing system according to an embodiment of the disclosure. The flushing system disclosed includes a flushing channel 3 and a nozzle 2. A flushing medium storage means 1 is disclosed in the figure. The nozzle 2 may be positioned in the area of the bore hole 15 during use in order to flush the bore hole 15. However, the nozzle may also be used for suppressing dust in the environment and does not have to be used in the area of the bore hole. According to the embodiment in figure 1 , the flushing channel 3 is arranged to cool a component 4 that generates heat. The flushing channel 3 is arranged so that heat generated by the component 4 that generates heat is transferred to the first flushing medium in the flushing channel 3. The flushing channel 3 is conveying first flushing medium to the nozzle 2. At the same time as the first flushing medium is conveyed through the flushing channel 3 to the nozzle 2, the component 4 may be cooled and the cooling may be performed when the component is used. When flushing is performed by a drill rig, the cooling requirement may be the largest.

[0078] For example, when an engine of a drill is in operation, the requirement of cooling may be high. At the same time, when drilling is performed the flushing of the bore hole may be used and the cooling of the drill engine will be performed at the same time. I.e., the cooling requirement when drilling will fit with the use of the flushing system.

[0079] According to the embodiment of Figure 1 the flushing system is arranged for cooling the component 4 which generates heat. In Figure 1 a flushing medium channel 18 for providing a second flushing medium is schematically shown. The flushing medium channel 18 and the flushing channel 3 may be combined in a suitable way and in a suitable location of the channels. The at least one flushing medium channel 18 and the at least one flushing channel 3 are connected to a common channel for providing a mixture of second flushing medium and first flushing medium.

[0080] Figures 1 to 16 show embodiments of the disclosure, where a flushing system is shown.

[0081] Further, flushing medium storage means, components and channels are also shown in the embodiments. In the description of the figures below, the description of some parts of the embodiments are not mentioned for all figures. The embodiments are only examples.

[0082] Further, an embodiment of Figure 2 discloses a flushing system and a flushing medium storage means 1 is disclosed. The embodiment comprises a component 5 which requires heat. The first flushing medium in the flushing medium storage means 1 or in the flushing channel 3, needs to have a temperature which is high enough to heat the component 5. This may be achieved by that the first flushing medium in the flushing medium storage means 1 is heated. An alternative is that the flushing medium storage means 1 is comprised in an area which is warmer than the position of the component 5. Further, the first flushing medium in the flushing channel 3 at the location of the component 5, needs to have a higher temperature than the component 5. According to the embodiment of Figure 2, the flushing system is arranged for heating the component 5 that requires heat.

[0083] In Figure 3 an embodiment of a flushing system is disclosed and a flushing medium storage means 1 is disclosed. The embodiment of Figure 3 further comprises an optional circulating channel 8. The circulating channel 8 is arranged to convey first flushing medium from the flushing medium storage means 1 and return it back to the flushing medium storage means 1. A component 4, which generates heat, is arranged so that heat generated by the component 4 is transferred to the first flushing medium in the optional circulating channel 8. The first flushing medium is conveyed back to the flushing medium storage means 1 in which the temperature of the first flushing medium will rise. The first flushing medium of the flushing medium storage means 1 is conveyed via the flushing channel 3 to the nozzle 2. The function of the first flushing medium for flushing is not affected by that the temperature has been raised. In Figure 3 is a heat exchanger 50 schematically shown. In this embodiment in Figure 3, heat transferred from the component 4 to first flushing fluid in the optional circulating channel 8, is transferred via the heat exchanger 50. The heat exchanger 50 may be used in further embodiments, but is only shown in Figure 3.

[0084] The embodiment of Figure 4 discloses a component 5 which requires heat. The embodiment discloses a flushing system and a flushing medium storage means 1 is disclosed. The embodiment further comprises an optional circulating channel 8. The optional circulating channel 8 is arranged so that heat is transferred from the first flushing medium in the optional circulating channel 8 to heat the component 5 that requires heat. The first flushing medium of the flushing medium storage means 1 may have a higher temperature than the component 5 or the first flushing medium of the optional circulating channel may have a higher temperature than the component 5 at the location of the component 5. The first flushing medium conveyed in the flushing channel 3 is conveyed to a nozzle 2 and may be used for flushing the bore hole 15.

[0085] Figure 5 shows an embodiment, wherein a first optional circulating channel 8 is arranged so that heat generated by at least one component 4, that generates heat, is transferred to the first flushing medium of the first optional circulating channel 8. A second optional circulating channel 9 is arranged so that heat is transferred to at least one component 5, that requires heat, from the first flushing medium of the second optional circuit channel 9. The component 4, that generates heat, is cooled, and the component 5, that requires heat, is heated. The cooling of component 4 and the heating of the component 5 may be performed at the same time.

[0086] The cooling and heating may alternatively be performed separately. The cooling of component 4 may be performed and the heat generated from component 4 will be transferred to the first flushing medium of the first optional circulating channel 8. During this time, the second optional circulating channel 9 will be closed from first flushing medium communication with the flushing medium storage means 1. When the first flushing medium of the first optional circulating channel 8 is conveyed back to the flushing medium storage means 1 the temperature of the first flushing medium in the flushing medium storage means 1 will be raised. After some time, the flow of first flushing medium in the first optional circulating channel 8, which is arranged so that heat generated by the component 4 is transferred to the first flushing medium of the first circulating channel 8, is stopped by closing the first flushing medium communication of the first optional circulating channel 8 with the flushing medium storage means 1. Then the second optional circulation channel 9 will be opened and the first flushing medium of the circulation channel 9 may be conveyed to and from the flushing medium storage means 1. The second optional circulating channel 9 is arranged to heat the component 5 that requires heat while the first flushing medium in the second optional circulating channel 9 is conveyed from the flushing medium storage means 1 and back to the flushing medium storage means 1. When the first flushing medium of the second optional circulating channel 9 is conveyed back to the flushing medium storage means 1 the temperature of the first flushing medium in the flushing medium storage means 1 will be lowered. The closing and opening of the optional circulating channels 8, 9 may be performed with control valves 11. The control valves are schematically shown in the figure and may be arranged on other locations. The embodiment of figure 5 shows control valves 11 as an example and the control valves are not necessary. Control valves may also be used in other embodiments, for example in the embodiments of the other figures.

[0087] The at least one optional circulating channel 8, 9 convey first flushing medium from the at least one flushing medium storage means 1 and return it back to the at least one flushing medium storage means 1. The flushing medium storage means 1 has openings wherein the optional circulating channel 8, 9 is connected to the flushing medium storage means 1 and first flushing medium may be conveyed via the openings to and from the at least one optional circulating channel 8, 9. Each end of a circulating channel 8, 9 is connected to an opening of the flushing medium storage means 1. The openings may be arranged in all embodiments comprising circulating channels 8, 9.

[0088] The disclosure may comprise a closed circuit channel 6, 7. By a closed circuit channel is e.g., meant that no first flushing medium can enter the closed circuit channel 6, 7 or no closed circuit channel medium may flow out from the closed circuit channel 6, 7. The closed circuit channel medium of the closed circuit channel 6, 7 is separate from the first flushing medium of the at least one flushing medium storage means 1.

[0089] In Figure 6 an embodiment showing a flushing system is disclosed, and the embodiment further comprises a flushing medium storage means 1 and closed circuit channel 6. The closed circuit channel 6 is a closed circuit meaning that the closed circuit channel medium will only be circulating in the closed circuit channel without medium connection with the first flushing medium of the flushing medium storage means 1. No first flushing medium may enter to the closed circuit channel 6 from the flushing medium storage means 1 and no closed circuit channel medium of the closed circuit channel 6 may go from the closed circuit channel 6 to the flushing medium storage means 1. The closed circuit channel 6 is arranged so that heat generated by the component 4 is transferred to the closed circuit channel medium in the closed circuit channel 6. The closed circuit channel 6, 7 may pass through the flushing medium storage means 1. A part of the closed circuit channel 6, 7 is passing through the flushing medium storage means 1, which can be seen in Figure 6, by the closed circuit channel 6 which has a part extending in the flushing medium storage means 1. Further, the flushing medium storage means 1 has openings wherein the at least one closed circuit channel 6, 7 can enter and exit the flushing medium storage means 1 for passing through the flushing medium storage means 1. This may also apply for other embodiments comprising closed circuit channels.

[0090] Further, according to an embodiment, Figure 7 discloses a component 5 which requires heat. A closed circuit channel 6 is arranged so that heat is transferred from the closed circuit channel medium in the closed circuit channel 6 to heat the component 5 that requires heat. The first flushing medium of the flushing medium storage means 1 may have a higher temperature than the component 5 or the closed circuit channel medium of the closed circuit channel 6 may have a higher temperature than the temperature of the position of the component 5. The closed circuit channel medium of the closed circuit channel 6 may then heat the component 5 which requires heat.

[0091] In Figure 8 is an embodiment, comprising two optional closed circuit channels 6, 7, shown. Figure 8 discloses an embodiment wherein a first closed circuit channel 6 is arranged so that heat generated by a component 4 that generates heat is transferred to the closed circuit channel medium of the closed circuit channel 6. Further, a second closed circuit channel 7 is arranged so that heat is transferred from the closed circuit channel medium of the second closed circuit channel 7 to the component 5, which component 5 requires heat. The cooling of component 4 and the heating of the component 5 may be performed at the same time.

[0092] The transfer of heat in the first closed circuit channel 6 and the transfer of heat in the second closed circuit channel 7 may alternatively be performed separately. The cooling of component 4 may be performed and the heat generated from component 4 will be transferred to the closed circuit channel medium of the first optional closed circuit channel 6. During this time, the closed circuit channel medium may be stopped from flowing in the second closed circuit channel 7. When the medium of the first closed circuit channel 6 is conveyed in the first closed circuit channel 6 through the flushing medium storage means 1 , the temperature of the first flushing medium in the flushing medium storage means 1 will be raised. Closed circuit channel medium will be conveyed in the first closed circuit channel 6 which will be passing through the flushing medium storage means 1 in the first closed circuit channel 6. After some time, the closed circuit channel medium in the first closed circuit channel 6, which is arranged to cool the component 4, may be stopped from flowing in the first closed circuit channel 6. Then the closed circuit channel medium in the second closed circuit channel 7 may be started to flow through the second closed circuit channel 7. The second closed circuit channel 7 is arranged so that the closed circuit channel medium of the second closed circuit channel 7 heats the component 5 that requires heat. When the medium of the second closed circuit channel 7 is conveyed in the second closed circuit channel 7 through the flushing medium storage means 1 , the temperature of the first flushing medium in the flushing medium storage means 1 may be lowered. The stopping and starting of the flow of the closed circuit channel medium of the optional closed circuit channels 6, 7 may be performed with control valves. Control valves can be arranged in a similar way as illustrated in figure 5.

[0093] In Figure 9 is a further embodiment of the disclosure shown. The embodiment of Figure 9 comprises a flushing channel 3. Two components 4, 5 are included in the embodiment. The flushing channel 3 is arranged so that heat generated by the component 4 that generates heat is transferred to the first flushing medium in the flushing channel 3 and heat is transferred from the first flushing medium in the flushing channel 3 to the component 5 that requires heat. The component 4 that generates heat is arranged downstream from the flushing medium storage means 1 and the component 5 that requires heat is arranged downstream from the component 4 that generates heat. By this arrangement a component 4 may be cooled by the first flushing medium in the flushing channel 3 and at the same time the component 5 that requires heat may be heated.

[0094] Figure 10 discloses a further embodiment. The flushing system is disclosed including a flushing channel 3 and a nozzle 2. A flushing medium storage means 1 and two components 4, 4 which generate heat are included in the embodiment.

Further, the closed circuit channel 6, 7 medium in the at least one closed circuit channel may be water.

[0102] The first flushing medium may be added to or combined with a second flushing medium. In figure 1 is a flushing medium channel 18 shown. The first flushing medium may be combined with a second flushing medium as shown in figure 1. Any of the embodiments in figures 2-16 may also comprise a flushing medium channel 18.

[0103] A second flushing medium may be gas, liquid or a combination of gas and liquid. A second flushing medium may be for example a second flushing medium in the form of a compressed gas, such as compressed air, supplied from a compressor. The second flushing medium may comprise liquid or may consist of a liquid. The liquid may be water.

[0104] When flushing a bore hole, the flushing may be performed with a mixture of a first flushing medium and a second flushing medium.

Further, a component that may require heat may be a driving compartment 34 of a drill rig 10. A further example of a component that may require heat may be a battery system which need to be warmed in order to be used for starting in a cold climate.

[0113] In some embodiments, heat may be needed to be transferred to the first flushing medium in the flushing medium storage means 1, the first flushing medium in the flushing channel 3, the first flushing medium in the at least one optional circulating channel 8, 9 and / or the closed circuit channel medium in the at least one optional closed circuit channel 6, 7. Heat may be transferred from an external source. This could be the case if the drill rig 10 e.g. only comprises at least one component 5 that requires heat.

[0114] The drill rig 10 may be a mobile surface drill rig 10. Drill rigs which are used on the surface do not usually have access to medium which can be used for flushing. The solution of the disclosure is advantageous since the first flushing medium of the flushing system may be used for cooling components and heating components of a mobile surface drill rig.

[0115] It is now referred to Figure 17 which shows a drill rig 10 as already described above. The flushing medium storage means 1 is shown to be comprised on the drill rig 10. This is only an example and should not be seen as limiting, and the flushing medium storage means 1 may also be comprised separate from the drill rig 10 (not shown in Figure 17). In the embodiment of Figure 17 a sensor 14, 16 is arranged in the components 4, 5 to determine a temperature T of the at least one component 4 that generates heat or the at least one component 5 that requires heat and sending the information from the at least one sensor 14, 16 to a second control unit 12. The second control unit 12 may be arranged on the drill rig 10 or outside the drill rig 10. The information may also be sent to a server or a cloudbased server, on site or off site. The second control unit 12 may control the heat transferred from a component 4 that generates heat so the temperature in component 4 is substantially constant or obtains a desired temperature. Further, the second control unit 12 may control the heat transferred to a component 5 that requires heat so the temperature in component 5 is substantially constant or obtains a desired temperature. The second control unit 12 may control the temperatures taking the sensor information into account. In the embodiment, the flushing medium storage means 1 comprises a sensor 13 to determine the temperature T and / or flushing level in the flushing medium storage means 1. Information is sent from the sensor 13 to the second control unit 12. Further, the drill rig of Figure 17 comprises a first control unit 17 and at least one optional control valve 11 configured to selectively open or close the at least one optional circulating channel, the at least one flushing channel 8, 9 and / or the at least one optional closed circuit channel 6, 7.

The driving compartment may be a component that requires heat. A circulating channel 8, 9, a flushing channel 3 or a closed circuit channel 6, 7 may be arranged so that first flushing medium or closed circuit channel medium can transfer heat to the driving compartment. When working in a cold environment, a process may cool a component that generates heat. The heat may be transferred to a first flushing medium in the at least one optional circulating channel 8, 9, a first flushing medium in the at least one flushing channel 3 and / or a closed circuit channel medium in the at least one optional closed circuit channel 6, 7. The flushing system may be arranged to heat a driving compartment.

[0117] The drill rig 10 may be an at least partially electrically driven drill rig 10. The drill rig may have one or more components which are electrically driven. Further, the transportation or driving of the drill rig may be at least partially electrically driven. An electrically driven engine may for example be complemented with a diesel engine. The transportation of driving of the drill rig may be completely electrically driven.

[0118] The component 4 that generates heat or the component 5 that requires heat may be configured to be connectable to an electrical supply. The electrical supply may be a battery, or it may be an electrical network.

[0119] The drill rig 10 may comprise a first control unit 17 and at least one control valve 11 configured to selectively open or close the at least one optional circulating channel 8, 9, the at least one flushing channel 3 and / or the at least one optional closed circuit channel 6, 7. Depending on if a component is to be cooled or heated, different channels need to be open for flow of medium in a channel. Cooling and heating may be performed in the drill rig. Cooling and heating may be performed at the same time. Further, cooling may be performed at one time and heating may be performed at another time. Cooling may be performed for a component 4 that generates heat, and then, heating may be performed for another component 5 that requires heat. For such a drill rig, a first control unit 17 and a control valve 11 may be useful in order to control the flow of medium in the different channels.

[0120] The first flushing medium may comprise a liquid and the drill rig 10 may comprise at least a second nozzle 20 connected to the at least one flushing channel 3. An embodiment showing a second nozzle 20 is shown in figure 16. The at least one second nozzle 20 may be configured to produce a mist of atomized liquid. The mist of atomized liquid may be used for cooling a component 4, which generates heat, on the drill rig. The mist may be sprayed onto a component 4 that generates heat. The mist may be sprayed onto an internal or external component. The mist of atomized liquid may also be used for suppressing dust. A drill rig 10 may have an electrical cable for connection to an electrical network. When the cable is connected to an electrical network, it may be heated. The mist of atomized liquid may be used for cooling a cable.
