[0027] In this embodiment, a discharge port 12 is formed at the bottom end of the inner annular groove 3. The discharge port 12 is used to discharge drilling fluid, which is convenient for taking out materials during use.

[0028] In this embodiment, one end of the side flow tube 2 is fixedly connected to a fixed disk 13, one end of the sealing plate 9 close to the fixed disk 13 is fixedly connected to a connecting column 14 and penetrates the fixed disk 13, and the other end of the connecting column 14 is fixedly connected to a limiting plate 15, and the limiting plate 15 is in contact with the fixed disk 13;

[0029] During the blocking installation, the limiting plate 15 moves toward the fixed plate 13 , and the installation is completed when the limiting plate 15 and the fixed plate 13 are tightly attached to each other.

[0030] In this embodiment, both sides of one end of the limiting plate 15 close to the fixed plate 13 are fixedly connected to fixed blocks 16, and the other ends of the two fixed blocks 16 are fixedly connected to trapezoidal blocks 17;

[0031] The fixing block 16 and the trapezoidal block 17 are combined together to form an L-shaped edge, which is convenient for subsequent installation and limiting.

[0032] In this embodiment, mounting grooves 18 are provided on both sides of one end of the fixing plate 13 close to the limiting plate 15, telescopic holes are provided at one end of the outer side of the mounting grooves 18, and limiting rods 19 are provided on the inner walls of the two telescopic holes;

[0033] The fixing block 16 and the trapezoidal block 17 are arranged in the installation groove 18, and the limiting rod 19 is clamped on the L-shaped edge, so the trapezoidal block 17 can be limited, thereby completing the installation operation, which is convenient and quick.

[0034] In this embodiment, telescopic grooves 20 are provided at both ends of the two telescopic holes, springs 21 are fixedly connected to the outer ends of the four telescopic grooves 20, sliders 22 are fixedly connected to the inner ends of the four springs 21, and the four sliders 22 are fixedly connected to the limit rods 19;

[0035] The spring 21 can bring the slider 22 back to its original position in the telescopic slot 20 , so that the limiting rod 19 automatically clamps the trapezoidal block 17 .

[0036] In this embodiment, the two limit rods 19 are in contact with the fixed block 16 and the trapezoidal block 17 respectively, and are used to block the trapezoidal block 17, and the four sliders 22 and the telescopic slot 20 are adapted in shape;

[0037] The slider 22 moves with the limiting rod 19 to return to its original position and contacts the trapezoidal block 17 and the fixed block 16, thus quickly completing the limiting process.

[0038] It should be noted that the utility model is a storage device for oilfield chemical products. When in use, it is only necessary to pull the limit rod 19 outward to release the limit of the trapezoidal block 17. At this time, the sealing plate 9 can be pushed outward under the pressure of the drilling fluid inside the storage tank 1, so that the drilling fluid is discharged from the discharge port 12, which is convenient for use.

[0039] After use, the limiting plate 15 can be pushed to move with the connecting column 14 to one side of the first annular groove 4, and the limiting ring 10 and the second airbag 11 are respectively inserted into the second annular groove 5 and the first annular groove 4. When the limiting ring 10 contacts the ball 7, it will push to move to the inner side of the placement groove 6, thereby squeezing the first airbag 8. At the same time, the second airbag 11 and the first airbag 8 will also squeeze each other, so that the sealing of the side flow tube 2 can be strengthened to prevent the drilling fluid from leaking or volatilizing, thereby avoiding pollution of the surrounding environment.

[0040] When the limit plate 15 is pushed, the fixed block 16 and the trapezoidal block 17 will be inserted into the installation groove 18, and when the trapezoidal block 17 and the limit rod 19 are in contact, the limit rod 19 will be squeezed to move the limit rod 19 outward. When the limit plate 15 and the fixed plate 13 are tightly attached together, the trapezoidal block 17 is also installed. At this time, the limit rod 19 will be moved inward by the reset action of the spring 21, thereby clamping the trapezoidal block 17 and completing the installation limit of the limit plate 15. Therefore, the blocking can be completed quickly, so that the discharge can be carried out according to the required amount to avoid waste caused by excessive discharge.
