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 protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a multi-channel pressure equalization distribution device for a hydraulic system in oil extraction, including multiple connecting seats 3, each with a connecting flange at both ends. The connecting seats 3 are connected to the hydraulic system pipelines via the connecting flanges, allowing the pipelines of the connecting seats 3 to be connected, so that hydraulic oil can flow into different branches through the multiple connecting seats 3. A quick-connect mechanism 2 is provided between the multiple connecting seats 3. Each of the multiple connecting seats 3 is equipped with a pressure sensor 5 and a pressure regulating mechanism 4. The pressure sensor 5 and the pressure regulating mechanism 4 are connected to a programmable PLC 1. The pressure sensor 5 is model PT124B-2506. The pressure sensor 5 can be used to monitor the hydraulic oil pressure in the multiple connecting seats 3 in real time, and the pressure can be adjusted and distributed by the pressure regulating mechanism 4 through the programmable PLC 1, thereby improving system efficiency and reliability.

[0022] The quick-connect mechanism 2 includes a T-shaped insert block 202. One end of the T-shaped insert block 202 has a first inclined surface 204 and a limiting groove 203. An insert groove 201 is formed on one side surface of the connecting seat 3. The T-shaped insert block 202 and the insert groove 201 are respectively disposed on both sides of the connecting seat 3. The T-shaped insert block 202 matches the insert groove 201, allowing the T-shaped insert block 202 to be inserted into the insert groove 201. A movable block 205 is provided at the top of the insert groove 201, and the bottom surface of the movable block 205 is fixedly connected... A guide slider 206 is connected to the connecting seat 3, and a guide groove is provided on the connecting seat 3. The movable block 205 is slidably connected to the connecting seat 3 through the guide slider 206 and the guide groove, so that the movable block 205 can move along the guide groove. A first spring 207 is provided at one end of the guide slider 206, and a trapezoidal block 208 is fixedly connected to the bottom surface of the guide slider 206. A movable locking block 209 is provided on one side of the bottom of the trapezoidal block 208. The bottom end of the movable locking block 209 extends into the embedded groove 201, so that it can engage with the T-shaped embedded block 201. 02 makes contact and can be inserted into the limiting groove 203 for locking. The bottom end of the movable block 209 is provided with a second inclined surface 210, and the top end of the movable block 209 is provided with a second spring 211. The first spring 207 is disposed between the guide slider 206 and the inner wall of the connecting seat 3, and the second spring 211 is disposed between the top of the movable block 209 and the inner wall of the connecting seat 3, so that the first spring 207 can be used to reset the guide slider 206, and the second spring 211 can be used to reset the movable block 209. A rotating seat 212 is fixedly connected to the movable block 209. A pry bar 213 is rotatably connected inside the rotating seat 212. A support seat 214 is provided at the bottom of the pry bar 213. The support seat 214 is fixedly installed inside the connecting seat 3, and the top of the support seat 214 contacts the bottom surface of the pry bar 213, so that the pry bar 213 can rotate around the support seat 214. The free end of the pry bar 213 contacts the inclined surface of the trapezoidal block 208, so that the movement of the trapezoidal block 208 can drive the pry bar 213 to rotate.

[0023] Please see Figure 1 and Figure 4The pressure regulating mechanism 4 includes a mounting base 401, which is fixedly mounted on the connecting seat 3. A rotating shaft 402 is rotatably connected inside the mounting base 401. A valve plate 403 is fixedly connected to the bottom end of the rotating shaft 402. A sealing ring 404 is fixedly connected to the side surface of the valve plate 403 to increase the sealing between the valve plate 403 and the inner wall of the connecting seat 3. A worm gear 405 is fixedly connected to the top end of the rotating shaft 402. A worm 406 is provided on one side of the worm gear 405. The self-locking function of the worm 406 and the worm gear 405 can improve the stability of the valve plate 403. A drive motor 407 is fixedly connected to the end of the worm 406. The drive motor 407 is a servo motor, which can be easily controlled. The drive motor 407 can drive the worm 406 to rotate, which in turn drives the worm gear 405 to rotate, which in turn drives the rotating shaft 402 to rotate, which in turn drives the valve plate 403 to rotate, thereby adjusting the opening and regulating the pressure inside the connecting seat 3.

[0024] During operation, the T-shaped insert block 202 is inserted into the insert groove 201. The T-shaped insert block 202 uses the first inclined surface 204 to push the second inclined surface 210 upward, which in turn pushes the movable locking block 209 upward and compresses the second spring 211. After the T-shaped insert block 202 is fully inserted into the insert groove 201, the movable locking block 209 is above the limiting groove 203. The second spring 211 releases pressure and pushes the movable locking block 209 into the limiting groove 203 for locking, thus completing the assembly.

[0025] When dismantling is required, push the movable block 205. The movement of the movable block 205 causes the trapezoidal block 208 to move. The trapezoidal block 208 pushes the pry bar 213 to rotate through its own inclined surface. The pry bar 213 rotates around the top of the support base 214. The rotation of the pry bar 213 causes the movable locking block 209 to move upward, pulling the movable locking block 209 out of the limiting groove 203, releasing the constraint on the T-shaped embedded block 202, and disassembling the connecting seat 3. This allows for flexible installation according to the actual number of devices used, improving the flexibility of use.

[0026] During use, pressure sensor 5 monitors the oil pressure in the branch in real time and transmits the monitored pressure signal to programmable PLC 1. Programmable PLC 1 controls drive motor 407 according to preset value. Drive motor 407 drives worm gear 406 to rotate. Worm gear 406 rotates, which in turn drives worm wheel 405 to rotate. Worm wheel 405 rotates, which in turn drives shaft 402 to rotate. Shaft 402 rotates, which in turn drives valve plate 403 to rotate, adjusting the opening so that the pressure inside connecting seat 3 can be regulated.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
