[0041] Working principle: When in use, since the top guide body 3 is fixedly installed inside the water distributor body 1 and the top connecting tube 2, the water distributor body 1 and the top connecting tube 2 can have a good protective effect on the top guide body 3, and by fixing the first bottom bracket 6, the second bottom bracket 7, and the bottom guide body 8 inside the bottom connecting tube 5 and the bottom joint 9, the first bottom bracket 6, the second bottom bracket 7, and the bottom guide body 8 can be well protected. By installing the first threaded protective sleeve 11 inside one end of the top joint 4 and installing the second threaded protective sleeve 12 outside one end of the bottom joint 9, the top joint 4 and the bottom joint 9 can be protected. When in use, when water flows through the top joint 4, the top connecting tube 5, and the bottom connecting tube 5, the top guide body 3 can be well protected. After the connecting tube 2 and the top guide body 3 are transported to the inside of the water distributor body 1, during normal water injection, the water enters the oil and casing annular space through the water injection channel of the plug 10 and the eccentric hole of the water distributor body 1 and is then injected into the formation; when water is injected into the inside of the top connecting tube 2 through the top joint 4, the water flow can be filtered by the cleaning component 14 inside the water filter tank 13, effectively avoiding the plug 10 and the eccentric hole being blocked when there are too many impurities, thereby affecting the normal drainage; the flip motor 145 outside the rotating frame 144 on one side of the mounting base 143 works, and the flip seat 148 can be driven to rotate between the two rotating frames 144 through the motor shaft, so that the second water filter frame 147 and the first water filter frame 147 respectively connected to the outside of the two flip seats 148 146 rotates. During the rotation process, the second water filter frame 147 is rotated first, and then the first water filter frame 146 is rotated, so that the anti-collision groove outside the water filter plate 149 on the end face of the first water filter frame 146 is convenient for fitting with the outer wall of the transmission shaft sleeve 1410 on the end face of the second water filter frame 147. After the flipping is completed, at this time, the water filter plates 149 on the end faces of the first water filter frame 146 and the second water filter frame 147 are located outside one end of the top joint 4, and the electric guide rail 141 inside the guide groove on the inner side of the water filter groove 13 works, and the guide rail slide 142 can drive the mounting base 143 to move up, so that the top end faces of the first water filter frame 146 and the second water filter frame 147 are convenient for fitting with one end of the top joint 4. When water flows through the top joint 4 and is injected into the top connection When the water flows into the interior of the receiving tube 2, the water flow is filtered by the water filter plate 149, thereby effectively filtering out impurities in the water. The filtered water flow impacts the spiral blade 1414 at the top of the transmission shaft 1411, which can drive the spiral blade 1414 to rotate. As the spiral blade 1414 rotates, the transmission shaft 1411 is driven to rotate inside the transmission bearing inside the transmission sleeve 1410. The rotating transmission shaft 1411 can drive the cleaning brush 1413 at the bottom of the follower support rod 1412 to clean the surface of the water filter plate 149, thereby preventing impurities from clogging the surface of the water filter plate 149, thereby affecting the filtering effect of the water filter plate 149. The filtered water is injected into the interior of the water distributor body 1 through the top guide body 3 through the water filter trough 13, thereby facilitating water distribution.When the surface of the water filter plate 149 needs to be cleaned, the water injection channel can be closed by the plug 10, and the second water filter frame 147 and the first water filter frame 146 on the side of the flip seat 148 can be reset by the flip motor 145. The water flow is injected into the filter tank 13 inside the top connection tube 2 through the top joint 4 to wash the first water filter frame 146 and the water filter plate 149 on the surface of the second water filter frame 147, so that the water flow flushes the impurities to the top guide body 3 and is discharged through the water distributor body 1, the bottom connection tube 5 and the bottom joint 9. ;

[0042] A method for using a water distributor for oil production comprises the following steps:

[0043] Step S1: When in use, since the top guide body 3 is fixedly installed inside the water distributor body 1 and the top connecting tube 2, the water distributor body 1 and the top connecting tube 2 can have a good protective effect on the top guide body 3, and by fixing the first bottom bracket 6, the second bottom bracket 7, and the bottom guide body 8 inside the bottom connecting tube 5 and the bottom joint 9, the first bottom bracket 6, the second bottom bracket 7, and the bottom guide body 8 can be well protected. By installing the first threaded protective sleeve 11 inside one end of the top joint 4 and installing the second threaded protective sleeve 12 outside one end of the bottom joint 9, the top joint 4 and the bottom joint 9 can be protected;

[0044] Step S2: When in use, after water flows through the top joint 4, the top connecting tube 2 and the top guide body 3 and is transported to the inside of the water distributor body 1, during normal water injection, the water flows through the water injection channel of the plug 10 and the eccentric hole of the water distributor body 1 into the annular space of the oil and casing and then is injected into the formation;

[0045] Step S3: When water is injected into the top connection tube 2 through the top joint 4, the water flow can be filtered by the cleaning assembly 14 inside the water filter tank 13, effectively preventing the plug 10 and the eccentric hole from being blocked when there are too many impurities, thereby affecting the normal drainage; the flip motor 145 outside the rotating frame 144 on one side of the mounting base 143 works, and the flip seat 148 can be driven to rotate between the two rotating frames 144 through the motor shaft, so that the second water filter frame 147 and the first water filter frame 146 respectively connected to the outside of the two flip seats 148 rotate. During the rotation process, the second water filter frame 147 is rotated first, Then the first water filter frame 146 is rotated, so that the anti-collision groove outside the water filter plate 149 on the end face of the first water filter frame 146 is convenient for fitting with the outer wall of the transmission shaft sleeve 1410 on the end face of the second water filter frame 147. After the flipping is completed, at this time, the water filter plates 149 on the end faces of the first water filter frame 146 and the second water filter frame 147 are located outside one end of the top joint 4, and the electric guide rail 141 inside the guide groove on the inner side of the water filter tank 13 works, and the guide rail slide 142 can drive the mounting base 143 to move up, so that the top end faces of the first water filter frame 146 and the second water filter frame 147 are convenient for fitting with one end of the top joint 4. When water flows through the top joint 4 and is injected into the top When the inside of the connecting tube 2 is connected, the water flow is filtered through the water filter plate 149, so as to effectively filter out impurities in the water. The filtered water flow impacts the spiral blade 1414 at the top of the transmission shaft 1411, which can drive the spiral blade 1414 to rotate. As the spiral blade 1414 rotates, the transmission shaft 1411 is driven to rotate inside the transmission bearing inside the transmission shaft sleeve 1410. The rotating transmission shaft 1411 can drive the cleaning brush 1413 at the bottom of the follower support rod 1412 to clean the surface of the water filter plate 149, so as to prevent impurities from clogging the surface of the water filter plate 149, thereby affecting the filtering effect of the water filter plate 149. The filtered water passes through the filter plate 149, and the filter plate 149 is cleaned. The filtered water tank 13 is injected into the interior of the water distributor body 1 through the top guide body 3, so as to facilitate water distribution. When the surface of the water filter plate 149 needs to be cleaned, the water injection channel can be closed by the plug 10, and the second water filter frame 147 and the first water filter frame 146 on one side of the flip seat 148 can be driven to reset by the flip motor 145. The water flows through the top joint 4 into the filter tank 13 inside the top connecting tube 2 to flush the first water filter frame 146 and the water filter plate 149 on the surface of the second water filter frame 147, so that the water flow flushes the impurities to the top guide body 3 and is discharged through the water distributor body 1, the bottom connecting tube 5 and the bottom joint 9.
