DETAILED DESCRIPTION
[0032] In order to make the technical scheme of the present application better understood by those skilled in the art, the present application will be further described in detail below with reference to the accompanying drawings.
[0033] Embodiment: Please refer to Figure 1 - Figure 5 A multifunctional fishing head, comprising a fishing barrel 1, a stand 2 installed on the top of the fishing barrel 1, a sliding sleeve 3 installed on the outside of the stand 2, and a lifting rope 4 installed on the top of the sliding sleeve 3, further comprising:
[0034] A rotating block 5 is rotatably connected inside the fishing barrel 1, a motor 16 is installed inside the stand 2, and the output end of the motor 16 is fixedly connected to the center of the top of the rotating block 5.
[0035] The rotating block 5 can be driven to rotate by controlling the motor 16.

The cleaning mechanism comprises a second sliding groove 8 formed in the interior of the rotating block 5, a second sliding block 9 slidably connected in the interior of the second sliding groove 8, and a scraping strip 10 fixedly connected to the bottom of the second sliding block 9. A plurality of springs 11 are fixedly connected to the top of the second sliding block 9, and the top ends of the springs 11 are fixedly connected to the inner wall of the top of the second sliding groove 8. A scraping ring 12 is further fixedly connected to the inner wall of the fishing barrel 1, and the scraping ring 12 is located below the rotating block 5. A mud collecting groove 13 is formed in the bottom of the rotating block 5, and the mud collecting groove 13 is located directly below the second sliding groove 8. The scraping strip 10 penetrates through the mud collecting groove 13, and the two sides of the bottom of the scraping strip 10 are provided with inclined grooves.
[0037] When the worker who dives into the interior of the oil well puts the fishing barrel 1 on the exterior of the drill bit, the lifting rope 4 is driven to move downward, the fishing barrel 1 moves downward synchronously under the action of its own gravity, and in this process, the scraping ring 12 scrapes off the dirt and impurities on the exterior of the drill bit. When the top of the drill bit abuts against the bottom of the scraping strip 10, the rotating block 5 rotates, thereby driving the scraping strip 10 to rotate synchronously along the top of the drill bit, and the dirt on the top of the drill bit is gathered on the same side of the scraping strip 10. With the continuous downward movement of the fishing barrel 1, the scraping strip 10 moves towards the interior of the second sliding groove 8, and the springs 11 are compressed. When the bottom of the rotating block 5 abuts against the top of the drill bit, the dirt and impurities gathered on the same side of the scraping strip 10 enter the interior of the mud collecting groove 13.
[0038] The fixing mechanism is installed in the interior of the rotating block 5 and the interior of the fishing barrel 1, and is used for fixing the cleaned drill bit. The fixing mechanism comprises a plurality of first electromagnets 14 installed in the interior of the rotating block 5 and a plurality of second electromagnets 15 installed on the inner wall of the fishing barrel 1. The second electromagnets 15 are located above the scraping ring 12.
[0039] After the dirt and impurities gathered on the same side of the scraping strip 10 enter the interior of the mud collecting groove 13, the first electromagnets 14 and the second electromagnets 15 are electrified at the same time, thereby simultaneously adsorbing and fixing the drill bit from the top and the side of the drill bit.
[0040] The protection mechanism is connected with the sliding sleeve 3 and the fishing barrel 1 respectively, and is used for supporting the bottom of the fixed drill bit. A plurality of first sliding grooves 6 are formed in the outer wall of the stand 2 along the height direction thereof, and a first sliding block 7 is slidably connected in the interior of each first sliding groove 6. The top of the first sliding block 7 is fixedly connected to the bottom of the sliding sleeve 3. The protection mechanism comprises a plurality of protection mechanisms, and the number of the protection mechanisms in the embodiment is four. The four protection mechanisms are arranged in a ring array around the lifting rope 4 as the center. The protection mechanism comprises a support 18 fixedly connected to the outer wall of the fishing barrel 1 and a connecting rod 19 hingedly connected to the outer wall of the sliding sleeve 3.

The included angle between the linkage frame 20 and the supporting block 21 is 90°.
[0041] After the drill bit is adsorbed and fixed, the lifting rope 4 drives the sliding sleeve 3 to move upward, the first sliding block 7 moves upward along the inner wall of the first sliding groove 6 synchronously, in the process, the four connecting rods 19 drive the bottom end of the four linkage frames 20 to rotate around the hinge point of the respective support 18 towards the drill bit, thereby driving the four supporting blocks 21 to rotate to the bottom of the drill bit, thereby providing auxiliary support to the drill bit during the upward movement of the drill bit driven by the lifting rope 4, improving the safety of the drill bit fishing.
[0042] A plurality of flow guide holes 17 are formed on the outer wall of the fishing barrel 1.
[0043] The flow guide holes 17 are arranged to allow the liquid inside the fishing barrel 1 to be discharged through the flow guide holes 17 during the entry of the drill bit into the fishing barrel 1.
[0044] Working principle: when the staff working in the oil well puts the fishing barrel 1 on the drill bit, drives the lifting rope 4 to move downward, the fishing barrel 1 moves downward synchronously under the action of its own gravity, in the process, the scraper ring 12 scrapes off the dirt and impurities on the outside of the drill bit, when the top of the drill bit abuts against the bottom of the scraper strip 10, since the rotating block 5 rotates, it drives the scraper strip 10 to rotate along the top of the drill bit synchronously, gathering the dirt on the top of the drill bit on one side of the scraper strip 10, as the fishing barrel 1 continues to move downward, the scraper strip 10 moves towards the inside of the second sliding groove 8, the spring 11 is compressed, when the bottom of the rotating block 5 abuts against the top of the drill bit, the dirt and impurities gathered on one side of the scraper strip 10 enter the mud collecting groove 13, after the dirt and impurities gathered on one side of the scraper strip 10 enter the mud collecting groove 13, the first electromagnet 14 and the second electromagnet 15 are energized at the same time, the drill bit is adsorbed and fixed from the top and the side, after the drill bit is adsorbed and fixed, the lifting rope 4 drives the sliding sleeve 3 to move upward, the first sliding block 7 moves upward along the inner wall of the first sliding groove 6 synchronously, in the process, the four connecting rods 19 drive the bottom end of the four linkage frames 20 to rotate around the hinge point of the respective support 18 towards the drill bit, thereby driving the four supporting blocks 21 to rotate to the bottom of the drill bit, thereby providing auxiliary support to the drill bit during the upward movement of the drill bit driven by the lifting rope 4, improving the safety of the drill bit fishing.
