[0002] With increasing environmental awareness and technological advancements, green exploration drilling rigs are gradually becoming important equipment in fields such as geological exploration and resource development. Green exploration drilling rigs aim to reduce environmental impact, improve energy efficiency, and utilize environmentally friendly materials and technologies to achieve efficient, safe, and environmentally friendly drilling operations.

[0003] After completing drilling operations, green exploration drilling rigs need to perform a pipe-pulling operation to remove the drill rods from the borehole. At this time, the drill rod surface often carries a large amount of silt or other deposits, necessitating cleaning. In existing technologies, drill rods are typically cleaned manually one by one, which is time-consuming, labor-intensive, and inefficient. Therefore, this invention proposes a drill rod cleaning device for green exploration drilling rigs to solve the aforementioned problems. Utility Model Content

[0004] The main purpose of this invention is to provide a green drilling rig drill pipe cleaning device to improve drill pipe cleaning efficiency.

[0005] To achieve the above objectives, the green exploration drilling rig drill rod cleaning device proposed in this utility model includes a cleaning cylinder, a water inlet pipe, and a mud scraper. The cleaning cylinder has openings at both ends, allowing the drill rod to pass through from one end to the other. The cleaning cylinder includes a cleaning cylinder body and a connecting seat detachably connected to one end of the cleaning cylinder body. A water storage chamber is formed inside the cleaning cylinder body. The water inlet pipe is connected to the outer wall of the cleaning cylinder body, with one end connected to the water storage chamber and the other end connected to a water source. A plurality of water outlet holes are formed on the inner wall of the cleaning cylinder body, and these outlet holes are connected to the water storage chamber. Brush bristles are provided on the inner wall of the cleaning cylinder body for brushing away deposits on the outer wall of the drill rod. A mud scraper is provided at the end of the connecting seat furthest from the cleaning cylinder body, and the mud scraper can abut against the outer wall of the drill rod for preliminary removal of deposits.

[0006] Preferably, a connecting block is connected to the outer wall of the cleaning cylinder body, and a connecting plate is connected to the side of the connecting block away from the cleaning cylinder body. The connecting plate is connected to the end of the drilling rig feed beam. The connecting plate has multiple connecting holes that penetrate the plate thickness, and the connecting holes are symmetrically distributed on both sides of the connecting block.

[0007] Preferably, the cleaning cylinder further includes an embedding plate, and the bristles are evenly distributed on one side wall of the embedding plate; the inner wall of the cleaning cylinder body has multiple axially extending embedding grooves, which are centrally symmetrically distributed about the axis of the cleaning cylinder body; the embedding plate is embedded in the embedding groove and is flush with the inner wall of the cleaning cylinder body; one end of the embedding groove passes through the bottom wall of the cleaning cylinder body, and the connecting seat can abut against the embedding plate.

[0008] Preferably, the brush bristles include soft bristles and hard bristles; the embedding plate includes a first embedding plate and a second embedding plate; the soft bristles are evenly distributed on one side wall of the first embedding plate; the hard bristles are evenly distributed on one side wall of the second embedding plate; the first embedding plate and the second embedding plate are spaced apart.

[0009] Preferably, the water outlet is disposed between two adjacent embedding grooves, and the plurality of water outlets are equally spaced along the axial direction of the cleaning cylinder body.

[0010] Preferably, the scraper includes two oppositely arranged scraping assemblies, and the drill rod can pass between the two scraping assemblies; the scraping assembly includes an arc-shaped plate, a protective pad, and a connecting rod; one end of the connecting rod is connected to the connecting seat, and the other end of the connecting rod is connected to the arc-shaped plate; the protective pad is provided on the side of the arc-shaped plate opposite to the connecting rod, and the protective pad is used to abut against the outer wall of the drill rod.

[0029] This utility model proposes a green drilling rig drill rod cleaning device.

[0030] Please refer to Figures 1 to 4The green exploration drilling rig drill rod cleaning device includes a cleaning cylinder, a water inlet pipe 3, and a scraper 4. The cleaning cylinder has openings at both ends, allowing the drill rod to pass through from one end to the other. The cleaning cylinder includes a cleaning cylinder body 1 and a connecting seat 2 detachably connected to one end of the cleaning cylinder body 1. A water storage chamber 12 is provided inside the cleaning cylinder body 1. The water inlet pipe 3 is connected to the outer wall of the cleaning cylinder body 1, with one end of the water inlet pipe 3 connected to the water storage chamber 12 and the other end connected to a water source. A plurality of water outlet holes 13 are provided on the inner wall of the cleaning cylinder body 1, and the water outlet holes 13 are connected to the water storage chamber 12. The inner wall of the cleaning cylinder body 1 is provided with bristles, which are used to brush away the deposits on the outer wall of the drill rod. A scraper 4 is provided at the end of the connecting seat 2 away from the cleaning cylinder body 1, and the scraper 4 can abut against the outer wall of the drill rod for preliminary scraping of deposits.

[0031] In this invention, the drill rod can pass through the cleaning cylinder. The cleaning cylinder body 1 has a water storage chamber 12, which is connected to a water source via an inlet pipe 3. The inner wall of the cleaning cylinder body 1 has several outlet holes 13 communicating with the water storage chamber 12, and the inner wall of the cleaning cylinder body 1 is provided with bristles. Therefore, when the drill rod passes through the cleaning cylinder, the water storage chamber 12 sprays water onto the outer wall of the drill rod through the outlet holes 13, and the bristles can scrub the outer wall of the drill rod, thus cleaning away the deposits on the outer wall of the drill rod, saving time and effort, and improving the efficiency of cleaning the drill rod. The end of the connecting seat 2 furthest from the cleaning cylinder body 1 is provided with a scraper 4. Therefore, before the drill rod enters the cleaning cylinder body 1 for cleaning, the scraper 4 can initially scrape off the deposits on the outer wall of the drill rod, which helps improve the cleaning effect. In summary, the green exploration drilling rig drill rod cleaning device is simple and practical, with good cleaning effect, which can greatly save the cost of manual cleaning and improve the efficiency of drill rod cleaning.

[0032] Specifically, the cleaning cylinder body 1 is cylindrical; the water inlet pipe 3 is located at the end of the cleaning cylinder body 1 away from the connecting seat 2; the end of the water inlet pipe 3 away from the cleaning cylinder body 1 is provided with a connector; and the mud scraper 4 is detachably connected to the connecting seat 2.

[0033] In this embodiment, the water inlet pipe 3 is connected to the valve port of the drilling rig's pressure relief valve. Furthermore, the water inlet pipe 3 is connected to a water flow booster device, such as a booster pump, to further increase the water flow pressure, thereby increasing the speed at which the water flows out of the outlet hole 13, thus improving the cleaning effect.

[0034] Preferably, a connecting block 6 is connected to the outer wall of the cleaning cylinder body 1, and a connecting plate 5 is connected to the side of the connecting block 6 away from the cleaning cylinder body 1. The connecting plate 5 is connected to the end of the drilling rig feed beam. The connecting plate 5 has a plurality of connecting holes 51 that penetrate the plate thickness, and the connecting holes 51 are symmetrically distributed on both sides of the connecting block 6.

[0035] The green exploration drilling rig drill rod cleaning device is fixedly installed at the end of the drilling rig feed beam and located below the drilling rig holder. When the drilling rig is lifted, it is pulled out by rotation. As the drill rod passes through the cleaning cylinder and the mud scraper 4, it rotates and moves simultaneously, facilitating comprehensive cleaning of the drill rod's outer wall and improving the cleaning effect. Specifically, the connecting hole 51 is a threaded hole, and the green exploration drilling rig drill rod cleaning device is bolted to the drilling rig feed beam. In this embodiment, there are six connecting holes 51, with three connecting holes 51 symmetrically arranged on each side of the connecting block 6.

[0036] Preferably, the cleaning cylinder further includes an embedding plate, and the bristles are evenly distributed on one side wall of the embedding plate; the inner wall of the cleaning cylinder body 1 has multiple axially extending embedding grooves 14, which are centrally symmetrically distributed about the axis of the cleaning cylinder body 1; the embedding plate is embedded in the embedding groove 14, and the embedding plate is flush with the inner wall of the cleaning cylinder body 1; one end of the embedding groove 14 passes through the bottom wall of the cleaning cylinder body 1, and the connecting seat 2 can abut against the embedding plate.

[0037] The bristles are mounted on the embedded plate, which is detachably connected to the inner wall of the cleaning cylinder body 1. This facilitates the replacement of worn bristles, improving the durability of the device. Furthermore, it allows for the selection of appropriate bristles based on the deposits on the outer wall of the drill rod, increasing the device's applicability and improving cleaning effectiveness. During operation, the connecting seat 2 is removed, and the embedded plate can be pushed out from the end of the embedded groove closest to the connecting seat 2 for replacement. Specifically, the embedded plate is elongated and curved to ensure its surface is flush with the inner wall of the cleaning cylinder body 1. Protrusions are provided on both sides of the embedded plate, and the embedded groove 14 matches the shape of the embedded plate, preventing the embedded plate from radially disengaging from the cleaning cylinder body 1.

[0038] Preferably, the brush bristles include soft bristles 7 and hard bristles 9; the embedding plate includes a first embedding plate 8 and a second embedding plate 10; the soft bristles 7 are evenly distributed on one side wall of the first embedding plate 8; the hard bristles 9 are evenly distributed on one side wall of the second embedding plate 10; the first embedding plate 8 and the second embedding plate 10 are spaced apart.

[0039] Specifically, the stiff-bristled brush 9 is used to remove firmly attached substances from the outer wall of the drill pipe, while the soft-bristled brush 7 is used to scrub the outer wall of the drill pipe more thoroughly. The combination of the two can effectively improve the scrubbing effect. Specifically, the length of the soft bristles 7 is greater than the length of the stiff bristles 9.

[0040] Preferably, the water outlet 13 is disposed between two adjacent embedded grooves 14, and the plurality of water outlets 13 are equally spaced along the axial direction of the cleaning cylinder body 1.

The linear arrangement of the water outlets 13 and the elongated arrangement of the brush bristles along the inner wall of the cleaning cylinder body 1 facilitates comprehensive cleaning of the outer wall of the drill rod, improving the cleaning effect.

[0042] Preferably, the scraper 4 includes two scraping assemblies arranged opposite each other, and the drill rod can pass between the two scraping assemblies; the scraping assembly includes an arc-shaped plate 41, a protective pad 42, and a connecting rod 43; one end of the connecting rod 43 is connected to the connecting seat 2, and the other end of the connecting rod 43 is connected to the arc-shaped plate 41; the protective pad 42 is provided on the side of the arc-shaped plate 41 facing away from the connecting rod 43, and the protective pad 42 is used to abut against the outer wall of the drill rod.

[0043] The scraper assembly can effectively scrape off larger deposits on the outer wall of the drill rod. The protective pad 42 can effectively contact the outer wall of the drill rod to ensure the scraping effect, while also effectively preventing the scraper blade from scratching or damaging the drill rod surface, thus extending the service life of the drill rod. Specifically, the scraper assembly is detachably connected to the connecting seat 2, for example, by bolts; the arc plate 41 is semi-circular, and the arc plates 41 of two scraper assemblies can abut against each other to form a circular space through which the drill rod can pass; the protective pad 42 can be a rubber pad.

[0044] Furthermore, the bottom wall and side wall of the arc-shaped plate 41 are connected by a beveled transition to improve the ability to scrape off adhering substances. Even further, telescopic components are symmetrically arranged on both sides of the connecting seat 2, and the connecting rod is connected to the telescopic components. The telescopic components are used to adjust the relative distance between the two arc-shaped plates 41, thereby accommodating drill rods of different diameters.

[0045] Preferably, a first flared end 11 is provided at the end of the cleaning cylinder body 1 away from the connecting seat 2; the end of the first flared end 11 facing away from the connecting seat 2 is the larger end. The larger end of the first flared end 11 facing upwards facilitates the insertion of the drill rod into the cleaning cylinder body 1.

[0046] Preferably, the end of the connecting seat 2 away from the cleaning cylinder body 1 is provided with a second flared end 21; the end of the second flared end 21 facing away from the cleaning cylinder body 1 is the larger end. The larger end of the second flared end 21 facing downwards facilitates the removal of adhering substances from the outer wall of the drill rod from the cleaning cylinder, preventing the adhering substances from accumulating inside the cleaning cylinder and affecting the cleaning effect.

[0047] Preferably, the cleaning cylinder body 1 is threadedly connected to the connecting seat 2.

[0048] The threaded connection facilitates easy assembly and disassembly, making it convenient to replace the brush bristles. Specifically, the lower part of the cleaning cylinder body 1 is provided with an external thread, and the upper part of the connecting seat 2 is provided with an internal thread that matches the external thread, so that the cleaning cylinder body 1 and the connecting seat 2 are threadedly connected.

[0049] Preferably, the connecting rod 43 includes a first rod and a second rod that are perpendicular to each other; the first rod is connected to the outer wall of the connecting seat 2; the second rod abuts against the bottom wall of the connecting seat 2 and is connected to the arc-shaped plate 41.

The first rod is connected to the side wall of the connecting seat 2, which facilitates the assembly and disassembly of the mud scraping assembly. The second rod abuts against the bottom wall of the connecting seat 2, so that the bottom wall of the connecting seat 2 can provide some support for the second rod during mud scraping, thereby improving the structural strength.
