Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, specifically a deep-sea oil drill bit anti-sway stabilization device. Background Technology

[0002] In deep-sea oil drilling, due to factors such as rapid water flow, complex seabed, and great drilling depth, the drill bit is prone to swaying during the drilling process. This not only affects drilling efficiency but may also cause the drilling trajectory to deviate from the intended target, and even lead to safety accidents. Therefore, the research and application of anti-sway stabilization devices for deep-sea oil drill bits are particularly important.

[0003] Anti-sway stabilization devices for deep-sea oil drill bits are widely used in deep-sea oil drilling operations. By using these devices, drilling efficiency can be significantly improved, drilling costs reduced, and the occurrence of safety accidents decreased. Specifically, these devices ensure that the drill bit remains stable during drilling, preventing deviation from the predetermined trajectory; at the same time, they also reduce drill bit wear and damage, extending its service life.

[0004] Existing oil drilling tools generally use a combination of drill bit and sleeve for direct drilling. However, during use and observation, it has been found that when the drill bit comes into contact with a relatively hard rock layer, the drill bit will shake, causing the drill pipe and sleeve to come into contact and resulting in damage to the drill pipe.

[0005] Therefore, a deep-sea oil drill bit anti-sway stabilization device is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A deep-sea oil drill bit anti-sway stabilization device of this utility model includes a rotating shaft; a sleeve is fixedly connected to the end of the rotating shaft; a drill bit is disposed outside the rotating shaft; multiple fixed seats are fixedly connected to the rotating shaft; a connecting assembly is fixedly connected to the fixed seats; a connecting plate is fixedly connected to the end of the connecting assembly; a pair of fixed columns are fixedly connected to the connecting plate; a roller is rotatably connected between the pair of fixed columns. By fixing multiple fixed seats to the rotating shaft, fixing the connecting assembly to the fixed seats, and rotatably connecting the roller between the pair of fixed columns, when the rotating shaft rotates, it drives the roller to roll on the inner wall of the drill bit, which can limit the sway amplitude of the rotating shaft during use and reduce the situation where the rotating shaft sways excessively due to vibration when the drill bit contacts the seabed during use.

[0008] Preferably, the connecting assembly includes a first telescopic rod; the first telescopic rod and the fixed seat are fixedly connected; the other end of the first telescopic rod and the connecting plate are fixedly connected; the first telescopic rod is located inside the spring; by fixing the first telescopic rod between the fixed seat and the connecting plate, and fixing the spring to the outside of the first telescopic rod, when the shaft shakes too much, the first telescopic rod is compressed; when the shake decreases, the spring pushes the roller out to contact the inner wall of the drill bit, which can buffer the shaking generated by the shaft and reduce the possibility of damage to the shaft due to excessive shaking.

[0009] Preferably, a plurality of second telescopic rods are fixedly connected to the fixed base; the other end of the second telescopic rod is fixedly connected to the connecting plate. By fixing a plurality of second telescopic rods to the fixed base, the second telescopic rods are compressed when the spring is compressed and extended when the spring is extended, which enables the spring to operate stably during compression and extension and reduces the shaking of the connecting plate during use.

[0010] Preferably, a pair of fixing plates are fixedly connected to the connecting plate; multiple brush bristles are fixedly connected to the fixing plates. By fixing multiple brush bristles to the fixing plates, when the brush bristles move, they contact the inner wall of the drill bit to clean the inner wall of the drill bit, reducing the situation where impurities and debris adhere to the inner wall of the drill bit during use, which would cause the roller to run unevenly on the inner wall of the drill bit.

[0011] Preferably, a scraper is fixedly connected to the connecting plate; the scraper is located between the connecting plate and the roller. By fixing the scraper to the connecting plate, when the roller moves, the scraper contacts the roller surface to clean the roller surface, reducing the situation where impurities and debris adhere to the roller surface during use, which would make it difficult for the roller to move normally.

[0012] Preferably, an elastic cloth is fixedly connected to the fixed base; the spring and the second telescopic rod are located inside the elastic cloth; the other end of the elastic cloth is fixedly connected to the connecting plate. By fixing the elastic cloth to the fixed base, the elastic cloth is covered when it is extended, which can reduce the situation where impurities and debris adhere to the first telescopic rod during use, causing the first telescopic rod to jam.

[0013] The advantages of this utility model are:

[0014] 1. The deep-sea oil drill bit anti-sway stabilization device of this utility model has multiple fixed seats fixed to the rotating shaft, connecting components fixed to the fixed seats, and a roller rotatably connected between a pair of fixed columns. When the rotating shaft rotates, it drives the roller to roll on the inner wall of the drill bit, which can limit the sway amplitude of the rotating shaft during use and reduce the situation where the rotating shaft sways too much due to vibration when the drill bit comes into contact with the seabed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a deep-sea oil drill bit anti-sway stabilization device includes a rotating shaft 1; a sleeve 11 is fixedly connected to the end of the rotating shaft 1; a drill bit 12 is disposed outside the rotating shaft 1; multiple fixed seats 13 are fixedly connected to the rotating shaft 1; a connecting assembly 14 is fixedly connected to the fixed seat 13; a connecting plate 15 is fixedly connected to the end of the connecting assembly 14; a pair of fixed columns 16 are fixedly connected to the connecting plate 15; a roller 17 is rotatably connected between the pair of fixed columns 16. During use, the rotating shaft 1 and the drill bit 12 are used in conjunction. When in use, the rotating shaft 1 is connected to the drive mechanism to rotate the rotating shaft 1. When the rotating shaft 1 rotates, it drives the sleeve 11 to rotate to perform drilling work. When the sleeve 11 rotates, it drives the fixed seat 13 to rotate. When the fixed seat 13 rotates, it drives the connecting assembly 14 to rotate. When the connecting assembly 14 rotates, it drives the connecting plate 15 to rotate. When the connecting plate 15 rotates, the roller 17 rolls on the inner wall of the drill bit 12. By fixing multiple fixed seats 13 to the rotating shaft 1, fixing the connecting assembly 14 to the fixed seat 13, and rotating the roller 17 between a pair of fixed columns 16, the rotation of the rotating shaft 1 drives the roller 17 to roll on the inner wall of the drill bit 12. This can limit the shaking amplitude of the rotating shaft 1 during use and reduce the situation where the rotating shaft 1 shakes too much due to vibration when the drill bit 12 contacts the seabed during use.

[0025] like Figure 2 As shown, the connecting assembly 14 includes a first telescopic rod 2; the first telescopic rod 2 and the fixed seat 13 are fixedly connected; the other end of the first telescopic rod 2 and the connecting plate 15 are fixedly connected; the first telescopic rod 2 is located inside the spring 21; when the sleeve 11 contacts the seabed and causes shaking, the rotating shaft 1 shakes; when the shaking is too large, the rotating shaft 1 moves towards the drill bit 12, at which time the spring 21 is compressed; when the shaking amplitude decreases, the spring 21, under its own elastic force, pushes the roller 17 towards the drill bit 12. When the roller 17 is pushed out, it contacts the inner wall of the drill bit 12 to maintain the stable operation of the rotating shaft 1. A first telescopic rod 2 is fixed between the fixed seat 13 and the connecting plate 15, and a spring 21 is fixed outside the first telescopic rod 2. When the shaking amplitude of the rotating shaft 1 is too large, the first telescopic rod 2 is compressed. When the shaking amplitude is reduced, the spring 21 pushes the roller 17 out to contact the inner wall of the drill bit 12, which can buffer the shaking generated by the rotating shaft 1 and reduce the possibility of damage to the rotating shaft 1 due to excessive shaking.

[0026] like Figure 3As shown, multiple second telescopic rods 3 are fixedly connected to the fixed base 13; the other end of the second telescopic rod 3 is fixedly connected to the connecting plate 15. When the rotating shaft 1 shakes too much, the spring 21 is compressed. When the spring 21 is compressed, the second telescopic rod 3 is compressed accordingly. When the rotating shaft 1 tends to be stable, the second telescopic rod 3 is stretched accordingly. By fixing multiple second telescopic rods 3 to the fixed base 13, the second telescopic rod 3 is compressed accordingly when the spring 21 is compressed, and the second telescopic rod 3 is stretched accordingly when the spring 21 is stretched. This allows the spring 21 to operate stably during compression and stretching, reducing the shaking of the connecting plate 15 during use.

[0027] like Figure 4 As shown, a pair of fixing plates 4 are fixedly connected to the connecting plate 15; multiple bristles 41 are fixedly connected to the fixing plate 4. When the connecting plate 15 rotates, it drives the fixing plate 4 to rotate accordingly. When the fixing plate 4 rotates, it drives the bristles 41 to move accordingly. When the bristles 41 move, they contact the inner wall of the drill bit 12. At this time, the bristles 41 clean the inner wall of the drill bit 12. By fixing multiple bristles 41 to the fixing plate 4, when the bristles 41 move, they contact the inner wall of the drill bit 12 to clean the inner wall of the drill bit 12, reducing the situation where impurities and debris adhere to the inner wall of the drill bit 12 during use, causing the roller 17 to run unevenly on the inner wall of the drill bit 12.

[0028] like Figure 5 As shown, a scraper 5 is fixedly connected to the connecting plate 15; the scraper 5 is located between the connecting plate 15 and the roller 17. When the roller 17 is moving, the scraper 5 contacts the surface of the roller 17. At this time, the scraper 5 cleans the surface of the roller 17. By fixing the scraper 5 to the connecting plate 15, the scraper 5 contacts the surface of the roller 17 when the roller 17 is moving, thus cleaning the surface of the roller 17. This reduces the situation where impurities and debris adhere to the surface of the roller 17 during use, which could cause the roller 17 to have difficulty moving normally.

[0029] like Figure 5 As shown, an elastic cloth 6 is fixedly connected to the fixed base 13; the spring 21 and the second telescopic rod 3 are located inside the elastic cloth 6; the other end of the elastic cloth 6 is fixedly connected to the connecting plate 15. When the spring 21 is compressed, the elastic cloth 6 is compressed accordingly; when the spring 21 is extended, the elastic cloth 6 extends accordingly. When the elastic cloth 6 is extended, it covers the spring 21. By fixing the elastic cloth 6 to the fixed base 13 and covering the elastic cloth 6 when it is extended, the problem of impurities and debris adhering to the first telescopic rod 2 during use, which could cause the first telescopic rod 2 to jam, can be reduced.

[0030] Working principle: During use, the rotating shaft 1 and drill bit 12 work together. When in use, the rotating shaft 1 is connected to the drive mechanism to rotate it. When the rotating shaft 1 rotates, it drives the sleeve 11 to rotate for drilling. The rotation of the sleeve 11 drives the fixed seat 13 to rotate, which in turn drives the connecting assembly 14 to rotate. The rotation of the connecting assembly 14 then drives the connecting plate 15 to rotate. When the connecting plate 15 rotates, the roller 17 rolls on the inner wall of the drill bit 12. When the sleeve 11 contacts the seabed and vibrates, the rotating shaft 1 vibrates. When the vibration is too large, the rotating shaft 1 moves towards the drill bit 12, at which point the spring 21 is compressed. When the vibration amplitude decreases, the spring 21, under its own elastic force, pushes the roller 17 towards the drill bit 12. At this point, the roller 17 and the drill bit 12... The inner wall contact maintains the stable operation of the rotating shaft 1. When the rotating shaft 1 shakes too much, the spring 21 is compressed. When the spring 21 is compressed, the second telescopic rod 3 is also compressed. When the rotating shaft 1 becomes stable, the second telescopic rod 3 is stretched. When the connecting plate 15 rotates, it drives the fixing plate 4 to rotate. When the fixing plate 4 rotates, it drives the brush bristles 41 to move. When the brush bristles 41 move, they contact the inner wall of the drill bit 12. At this time, the brush bristles 41 clean the inner wall of the drill bit 12. When the roller 17 moves, the scraper 5 contacts the surface of the roller 17. At this time, the scraper 5 cleans the surface of the roller 17. When the spring 21 is compressed, the elastic cloth 6 is also compressed. When the spring 21 is stretched, the elastic cloth 6 is stretched. When the elastic cloth 6 is stretched, it covers the spring 21.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
