Description

Technical Field

[0001] This invention relates to the field of steam drilling technology, and in particular to an integrated steam drill. Background Technology

[0002] In glacier research, drilling operations are often required on the ice surface for purposes such as extracting ice cores for physical analysis, installing ice ablation probes, detecting the internal structure of the ice, and detecting the physical characteristics of the ice.

[0003] Glacier drilling rigs are divided into two categories: core drilling rigs and hole drilling rigs. Core drilling rigs are primarily used to extract ice cores. Although they can also create glacier boreholes, their bulky structure, numerous auxiliary devices, and slow drilling speed limit their use in glacier surveying where drilling is the primary objective. Hole drilling rigs mainly include steam drills, hot water drills, and electric drills. Due to the large overall weight, high energy consumption, and slow drilling speed of hot water drills and electric drills, steam drills are currently the most commonly used for glacier drilling.

[0004] The steam drill consists of a steam generator, a drill bit, and water pipes. During operation, the steam generator is placed stably on the ice surface. Its pressure vessel is pre-filled with 4-5L of clean water. The gas furnace at the bottom of the steam generator heats the water in the pressure vessel to boiling, generating steam. When the steam pressure reaches 0.2-0.3 MPa, the valve is opened, allowing steam to be ejected through the water pipe and the drill bit for drilling into the ice. The steam drill bit is a straight-through copper tube approximately 60 cm long, with one or more nozzles at the head to facilitate steam ejection. When the steam pressure drops to 0.05-0.1 MPa, the valve is closed, and the process is repeated once the steam pressure increases.

[0005] Existing steam drills have some insurmountable drawbacks in operation, such as: (1) In order to reduce the weight of the steam drill and make it easier to carry in glacial areas, the steam generators are all made of aluminum, and the walls of their pressure vessels are relatively thin. The working pressure is generally less than 0.3 MPa. Therefore, the drilling depth of existing steam drills is limited due to the low working pressure; (2) Current steam drills adopt a split design where the steam generator and the drill bit are separate. After the steam generator generates high-temperature steam, it is transported to the drill bit through a water pipe. Then the steam is sprayed out and drilled. In this process, although the water pipe is insulated to minimize the heat loss of steam during transportation, a considerable amount of heat is still lost through the water pipe wall due to the increase in water temperature because the borehole is filled with melt water. Moreover, as the drilling depth increases, the heat dissipation of the water pipe will also increase rapidly, thereby reducing the drilling rate. In addition, during the process of high-temperature steam reaching the drill bit through the water pipe, the steam expands in the pipe, which directly reduces the pressure and temperature of the steam at the nozzle of the drill bit. When the water pipe is long, the pressure and heat loss caused by the expansion in the pipe will be difficult to ignore, directly affecting the drilling efficiency of the drill bit. Summary of the Invention

The steam generator includes a coil and a combustion mechanism. The inlet end of the coil is connected to the outlet end of the gas supply pipe, and the combustion mechanism is located near the coil and can be connected to an external gas source. The combustion mechanism heats the gas-liquid mixture in the coil into steam by burning gas. One end of the drill bit is connected to the steam generator, and the other end is equipped with a nozzle connected to the outlet end of the coil.

[0008] Optionally, the atomizer is an atomizing tube, the gas-liquid mixing chamber is the inner cavity of the atomizing tube, the outer wall of the atomizing tube is provided with multiple atomizing holes, and the atomizing tube is fitted with a tubular filter that can filter out impurities in the water; the gas delivery pipe extends into the liquid storage chamber, the atomizing tube is located in the liquid storage chamber, and the upstream and downstream of the atomizing tube and the gas delivery pipe are connected.

[0009] Optionally, the nozzle has a flow channel, and the diameter of the flow channel gradually increases along the flow direction of the medium within the flow channel.

[0010] Optionally, the combustion mechanism includes a gas-air mixing chamber near the coil, with a nozzle on the gas-air mixing chamber and an ignition component on one side of the nozzle; the gas-air mixing chamber can be connected to an external gas source and an external high-pressure gas source, and the external air and gas are mixed in the gas-air mixing chamber and then sprayed out from the nozzle and ignited by the ignition component.

[0011] Optionally, the steam generator also includes a combustion chamber, in which the coil and combustion mechanism are located; a drill bit connector is detachably connected to one end of the combustion chamber, and the end of the drill bit connector away from the combustion chamber is detachably connected to the drill bit; the drill bit connector is provided with a first connecting pipe, one end of which is connected to the coil in the combustion chamber, and the other end of which is connected to the nozzle in the drill bit.

[0012] Optionally, both the liquid storage device and the combustion chamber are tubular, with one end of the liquid storage device and one end of the combustion chamber threaded together; a connector is provided in the liquid storage device or the combustion chamber, which can separate the liquid storage chamber of the liquid storage device from the inner cavity of the combustion chamber.

[0013] Optionally, the connector is provided with a second pipe, a third pipe, a fourth pipe, and a fifth pipe; one end of the second and third pipes are respectively connected to an external gas source and an external high-pressure gas source, and the other end of the second and third pipes are both connected to the gas-air mixing chamber cavity; one end of the fourth pipe is connected to the outlet end of the gas transmission pipeline, and the other end is connected to the inlet end of the coil; one end of the fifth pipe is connected to the combustion chamber cavity, and the other end is connected to an exhaust pipe leading to the outside.

[0014] Optionally, the second connector is connected to a gas pipe that can communicate with an external gas source at one end near the liquid storage unit, and the third connector is connected to an air pipe that can communicate with an external high-pressure gas source at one end near the liquid storage unit; one side of the gas transmission pipe, exhaust pipe, gas pipe and air pipe are all located inside the liquid storage unit.

[0015] Optionally, a flame observation hole is provided on one side of the combustion chamber, and a high-temperature resistant transparent glass is installed in the flame observation hole.

[0016] Optionally, the coil is a conical spiral coil.

[0017] The technical solution provided by the embodiments of the present invention has the following advantages compared with the prior art:

[0018] 1. By installing an atomizer on the gas pipeline, the water output from the liquid storage chamber can be atomized, and a place for mixing high-pressure air and atomized water droplets can be provided. When the high-pressure air flows through the atomizer, it will carry atomized water droplets. Therefore, when the high-pressure air carrying droplets flows through the coil, the gas-liquid mixture can be rapidly heated and pressurized and sprayed out through the nozzle. This design can generate steam pressure higher than that of conventional steam drills, which can significantly increase the drilling depth of steam drills.

[0019] 2. Since the drill bit is directly connected to the steam generator, and the outlet end of the coil is directly connected to the nozzle inside the drill bit, the steam can be delivered to the nozzle immediately after it is generated. Therefore, the steam drill of the present invention can reduce the heat loss of steam during the transportation process. Compared with the traditional split-type steam ice drill, the steam drill of the present invention can maximize the preservation of the heat energy and pressure of the steam. Even when the drilling depth increases, it can reduce the energy loss caused by the transportation distance, thereby ensuring the working efficiency of the drill bit.

[0020] 3. By setting up a steam generator including a coil and a combustion mechanism, the combustion mechanism can directly heat the gas-liquid mixture in the coil by burning gas, and heat the gas-liquid mixture into steam with a certain pressure; the structure of the coil can more efficiently convert the heat of the gas into the heat energy of the medium, so that the medium can be rapidly vaporized in the closed coil and form high pressure. Therefore, the steam drill of the present invention can break through the pressure limit of 0.3MPa and can drill into deeper ice layers. Attached Figure Description

An atomizer is connected to the gas supply pipe 32, and the atomizer has a gas-liquid mixing chamber that is connected upstream and downstream of the gas supply pipe 32. Water stored in the liquid storage chamber is atomized into water droplets by the atomizer and flows into the gas-liquid mixing assembly. The gas is mixed with high-pressure air in the gas pipeline 32 to form a gas-liquid mixture. The steam generator 2 is equipped with a coil 21 and a combustion mechanism 4. The inlet end of the coil 21 is connected to the outlet end of the gas pipeline 32. The combustion mechanism 4 is close to the coil 21 and can be connected to an external gas source. The combustion mechanism 4 heats the gas-liquid mixture in the coil 21 into steam by burning the gas. One end of the drill bit 1 is connected to the steam generator 2, and the other end is equipped with a nozzle 11. The nozzle 11 is connected to the outlet end of the coil 21.

[0034] In this embodiment, the air in the gas pipeline 32 is high-pressure air.

[0035] like Figure 4 and Figure 5 As shown, the combustion mechanism 4 includes a gas-air mixing chamber 41 near the coil 21. The gas-air mixing chamber 41 is provided with a nozzle 43, and an ignition component 42 is provided on one side of the nozzle 43.

Currently, the existing ignition high-voltage pack 46 can integrate ignition and flame sensing functions, so the ignition high-voltage pack 46 also has a control function.

[0038] like Figure 1 , Figure 3 and Figure 6 As shown, the steam generator 2 also includes a combustion chamber 22, and the coil 21 and the combustion mechanism 4 are both located in the combustion chamber 22. One end of the combustion chamber 22 is detachably connected to a drill bit connector 5, and the end of the drill bit connector 5 away from the combustion chamber 22 is detachably connected to the drill bit 1. The drill bit connector 5 is provided with a first connecting pipe 51, one end of the first connecting pipe 51 is connected to the coil 21 in the combustion chamber 22, and the other end is connected to the nozzle 11 in the drill bit 1.

[0039] In this embodiment, the drill bit connector 5 is entirely based on existing technology.

[0040] like Figure 1 , Figure 3 and Figure 7 As shown, both the liquid storage component 31 and the combustion chamber 22 are tubular bodies, with one end of the liquid storage component 31 and one end of the combustion chamber 22 being threadedly connected; the combustion chamber 22 is provided with a connector 6, which can separate the liquid storage cavity of the liquid storage component 31 from the inner cavity of the combustion chamber 22.

[0041] In this embodiment, since the drill bit 1 and the drill bit connector 5 are threadedly connected, the drill bit connector 5 and the combustion chamber 22 are threadedly connected, and the combustion chamber 22 and the liquid storage device 31 are threadedly connected; in order to facilitate component disassembly and maintenance, the outer walls of the drill bit 1, the drill bit connector 5, the combustion chamber 22 and the liquid storage device 31 are provided with wrench lap surfaces at opposite ends.

[0042] The connector 6 is provided with a second pipe 61, a third pipe 62, a fourth pipe 63, and a fifth pipe 64; one end of the second pipe 61 and the third pipe 62 are respectively connected to an external gas source and an external high-pressure gas source, and the other end of the second pipe 61 and the third pipe 62 are both connected to the inner cavity of the gas-air mixing chamber 41; one end of the fourth pipe 63 is connected to the outlet end of the gas transmission pipeline 32, and the other end is connected to the inlet end of the coil 21; one end of the fifth pipe 64 is connected to the inner cavity of the combustion chamber 22, and the other end is connected to an exhaust pipe 65 leading to the outside.

[0043] The second connecting pipe 61 is connected to a gas pipe 66 that can be connected to an external gas source at one end near the liquid storage unit 31, and the third connecting pipe 62 is connected to an air pipe 67 that can be connected to an external high-pressure gas source at one end near the liquid storage unit 31; one side of the gas transmission pipe 32, the exhaust pipe 65, the gas pipe 66 and the air pipe 67 are all located inside the liquid storage unit 31.

[0044] In this embodiment, the gas supply pipe 32, exhaust pipe 65, gas pipe 66 and air pipe 67 are wrapped with wire harness corrugated tubing or waterproof tape to form a pipe bundle.

[0045] A flame observation hole 23 is provided on one side of the combustion chamber 22, and a high-temperature resistant transparent glass is installed in the flame observation hole 23.

[0046] like Figure 3 and Figure 8 As shown, the atomizer is an atomizing tube 9, the gas-liquid mixing chamber is the inner cavity of the atomizing tube 9, the outer wall of the atomizing tube 9 is provided with multiple atomizing holes, and the atomizing tube 9 is fitted with a tubular filter element 91 that can filter impurities in the water; the gas supply pipe 32 extends into the liquid storage chamber, the atomizing tube 9 is located in the liquid storage chamber, and the upstream and downstream of the atomizing tube 9 and the gas supply pipe 32 are connected.

[0047] In this embodiment, the diameter of the atomizing hole is between 0.2 and 0.6 mm, and the filter element 91 is made of high-density filter cotton.

[0048] The coil 21 is a conical hollow spiral coil. In this embodiment, the coil 21 is made of copper.

[0049] The nozzle 11 has a flow channel, and the diameter of the flow channel gradually increases along the flow direction of the medium inside the flow channel.

[0050] In this embodiment, the external gas source is an air pump 7, and the outlet of the air pump 7 is connected to the gas transmission pipeline 32 and the air pipe 67 via a diversion tee pipe 68; the external gas source is a gas cylinder 8, and the gas cylinder 8 is connected to the gas pipe 66; a first valve 69 is provided on the air pipe 67.

[0051] Working principle:

[0052] The drill rod, formed by connecting the drill bit 1, steam generator 2, and gas-liquid mixing assembly 3, is placed vertically on the ice surface. Clean water is added to the storage chamber from the top of the storage container 31. The switches of the air pump 7 and gas tank 8 are turned on to introduce a small amount of air and gas into the gas-air mixing chamber 41. The mixture ejected from the nozzle 43 is ignited by the ignition assembly 42. The flame condition is observed through the flame observation hole 23. The air pump 7 and gas tank 8 are adjusted to make the flame stable, the firepower moderate, and the steam ejected from the nozzle 11 powerful. During this process, the high-pressure air in the gas pipeline 32 carries mist-like water droplets to the coil 21 for rapid heating. The steam after being heated and pressurized is ejected through the nozzle 11 at the end of the drill bit 1 to impact and melt the ice.

[0053] When the liquid storage unit 31 is completely submerged in the borehole, the melt water can flow into the liquid storage unit 31 from its top to form a positive circulation for water supply; the exhaust gas generated after the flame combustion impacts the coil 21 and the drill bit connector 5 and then flows in reverse direction, flowing towards the side where the connector 6 is located, and then is discharged through the exhaust pipe 65; during the process of the exhaust gas being transported through the exhaust pipe 65, heat exchange occurs with the melt water outside the pipe, causing the exhaust gas temperature to drop rapidly, thereby avoiding damage to the pipelines in the tube bundle caused by high temperature.

[0054] If the flame goes out unexpectedly during drilling, the flame sensing needle will send a high-level signal back to the ignition high-voltage transformer, illuminating its flameout indicator light and triggering the ignition high-voltage transformer to automatically ignite. After successful ignition, the flameout indicator light will go out. If ignition still fails after a few seconds, the machine should be stopped immediately for troubleshooting.

[0055] Observe the change in the pressure gauge reading on air pump 7. If the pressure continues to rise, it may mean that the nozzle is blocked by mud and sand in the ice. In this case, the machine should be stopped immediately to clear the air passage.

[0056] The above embodiments are merely a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
