Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a petroleum drilling rig transformer. Background Art

[0002] During oil drilling, the oil drilling rig drives the drilling tool to break the rock, drill underground, and drill a wellbore of a specified depth for the oil or gas extraction machine to obtain oil or natural gas. When the oil drilling rig is in use, a transformer is generally used to control the voltage and current conversion of the oil drilling rig to ensure the normal use of the oil drilling rig.

[0003] In a Chinese patent with publication number CN215298992U, a transformer for oil drilling rigs is disclosed, which is separated from the first groove by a support frame, so that the adhesive Velcro and the sponge ring slide out from the inside of the tube body. Under the action of the adhesive Velcro, the wet sponge ring is easy to remove and replace, thereby ensuring the water absorption effect of the sponge ring, which is beneficial to absorb raindrops dripping from the outside, and solves the problem that rainwater easily enters the transformer and causes a short circuit in the wires; however, when the above-mentioned transformer for oil drilling rigs is actually used, the sponge ring generally absorbs the water in the pipeline, but when the sponge ring is replaced, it needs to be pulled out from the adhesive Velcro, so that impurities of the sponge ring are easily left on the surface of the adhesive Velcro, resulting in the sponge ring after replacement. The sponge ring is easily not firmly adhered when it is pasted again, resulting in detachment, affecting the stable absorption of water by the sponge ring and affecting the use of the transformer.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1 An oil rig transformer is shown, comprising:

[0027] The transformer body 1 has two symmetrically distributed tubes 11 installed on the transformer body 1, a retractable support frame 12 is installed in the tube body 11, a sponge ring 13 is installed on the support frame 12, and the sponge ring 13 is used to absorb the moisture in the tube body 11; the structure and principle of the transformer body 1 and the support frame 12 are both prior arts, and specific reference is made to the comparative document (publication number CN215298992U, patent name is transformer for oil drilling rigs), which will not be repeated here.

[0028] As can be seen from the above, when in use, the support frame 12 is first moved outward along the tube body 11, and then the sponge ring 13 is installed on the support frame 12, thereby completing the installation of the sponge ring 13, and the support frame 12 moves into the tube body 11 and returns to its original position, so that the sponge ring 13 is in contact with the tube body 11, so that the sponge ring 13 absorbs the water droplets generated in the tube body 11, solving the problem that rainwater easily enters the transformer and causes a short circuit, ensuring that the transformer body 1 can maintain a stable connection with the oil drilling rig, and ensuring the normal use of the oil drilling rig.

[0029] refer to Figure 1-Figure 4 As shown, multiple mounting components 2 are used to fit the sponge ring 13 tightly in the tube body 11. Each mounting component 2 includes a support rod 22 that is telescopically mounted on the support frame 12 and a support plate 21 that is mounted in the sponge ring 13. The support rod 22 is provided with a fixing component for positioning and mounting the support plate 21. The support frame 12 is provided with an elastic component for driving the support rod 22 to adjust. The fixing component includes a fixing seat 28 fixed to the bottom end of the support rod 22 and a threaded groove 29 provided on the fixing seat 28 and the support plate 21, and a screw 27 is threadedly connected in the threaded groove 29.

[0030] The elastic component includes a through groove 23 opened on the support frame 12 for the support rod 22 to slide, and a contact plate 24 fixed on the support rod 22. A positioning cavity for the contact plate 24 to slide is opened in the through groove 23, and a spring 26 is arranged between the contact plate 24 and the positioning cavity; a moving plate 25 is also slidably connected in the positioning cavity, and the top end of the moving plate 25 is fixedly connected to one end of the spring 26, and the moving plate 25 is sleeved on the outside of the support rod 22.

[0031] Through the above technical solution:

[0032] When in use, first pick up one of the support plates 21 and move it close to one side of the support frame 12, then keep the thread groove 29 opened on the support plate 21 and the thread groove 29 opened on the fixing seat 28 overlapped, and then screw one end of the screw rod 27 into the thread groove 29, so that the support rod 22 and the support plate 21 are screwed and installed. Similarly, the other support plates 21 and the support rod 22 are positioned and installed in sequence. Secondly, the sponge ring 13 is placed in the tube body 11, and there is a distance between the support plate 21 and the tube body 11, so that pushing the support plate 21 drives the support rod 22 to move downward along the through groove 23, and the support rod 22 moves downward to drive the contact plate 24 to move downward along the positioning cavity, so that the spring 26 is located between the contact plate 24 and the moving The movable plates 25 are compressed, and then the distance between the support plate 21 and the tube body 11 is adjusted, and then the sponge ring 13 is sleeved on the outside of the support plate 21 and connected to one side of the support frame 12, and then the support plate 21 is loosened, and the tightening and reset thrust of the spring 26 drive the support plate 21 to reset, so that the outside of the sponge ring 13 is in contact with the tube body 11, and the sponge ring 13 and the tube body 11 can be stably fitted, so that the sponge ring 13 can maintain stable absorption of water in the tube body 11, thereby avoiding the existing adhesive Velcro surface easily leaving impurities of the sponge ring 13, resulting in the sponge ring 13 after replacement being easily stuck when it is pasted again, and it is easy to be detached, thereby ensuring the normal use of the transformer body 1.

[0033] In addition, refer to Figure 1-Figure 3 as well as Figure 5 As shown, a fine-tuning component 3 for pushing the movable plate 25 to move is provided on the support frame 12. The fine-tuning component 3 includes a mounting column 31 fixed to the bottom end of the movable plate 25 and a screw hole 32 opened at the bottom end of the support frame 12. A threaded column 33 is screwed on the bottom end of the support frame 12, and one end of the threaded column 33 is screwed into the screw hole 32 and rotatably connected to the bottom end of the mounting column 31; a handle 34 is also fixed to one end of the threaded column 33, and an anti-slip ring is fixedly sleeved on the outside of the handle 34; a retractable connecting column is also fixed in the positioning cavity, and the top end of the connecting column is fixed to the bottom end of the movable plate 25.

[0034] Through the above technical solution:

[0035] When in use, the handle 34 is pinched and rotated. At this time, the handle 34 rotates to drive the threaded column 33 and the screw hole 32 to rotate and move into the positioning cavity. Then the threaded column 33 pushes the mounting column 31 to move upward along the positioning cavity, and the movable plate 25 is adjusted upward along the positioning cavity. During the movement of the movable plate 25, the connecting column is driven to extend and retract, and the spring 26 is compressed between the contact plate 24 and the movable plate 25, thereby adjusting the tension of the spring 26. At the same time, the adjustment of the tension of the spring 26 adjusts the pressure between the support plate 21 and the sponge ring 13, so that the sponge ring 13 is tightly fitted between the support plate 21 and the tube body 11, which can ensure that the sponge ring 13 is tightly connected to the tube body 11 without being too tight, thereby ensuring the stable installation between the sponge ring 13 and the tube body 11, further avoiding the sponge ring 13 from detaching, and ensuring the normal use of the transformer main body 1.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
