This causes the third hinge block to drive the first damper to extend and drive the first spring to stretch and generate elastic force. At the same time, the third hinge block can drive the connecting block to move upward through the first damper, causing the second damper to shorten and drive the second spring to compress and generate elastic force.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-7 This utility model provides a technical solution: an oilfield additive injection device, including a storage tank 2, a threaded cover 1 on the top of the storage tank 2, a stirring and cleaning mechanism 4 on the top of the storage tank 2, a fixing plate 3 connected to the bottom of the storage tank 2, a water pump 6 connected to the top of the fixing plate 3, an injection pipe 7 connected to one side of the water pump 6, a suction pipe 8 connected to one side of the water pump 6, the other end of the suction pipe 8 passing through the bottom of the fixing plate 3 and communicating with the bottom of the storage tank 2, and a shock absorption mechanism 5 provided at the bottom of the fixing plate 3;

[0035] The stirring and cleaning mechanism 4 includes a support base 402 and an internal gear ring 406. The bottom of the support base 402 is connected to the top of the storage tank 2. A motor 401 is connected to the top of the support base 402. The output shaft of the motor 401 passes through the top of the support base 402 and is connected to a gear 405. A first external gear ring 407 meshes with one side of the gear 405. A connecting pipe 408 is connected to the inner wall of the first external gear ring 407. A water inlet pipe 403 is rotatably connected to the top of the connecting pipe 408. Multiple stirring blades 414 are connected to the outer wall of the connecting pipe 408. Two bent connecting pipes 410 are connected to the outer wall of the connecting pipe 408. A rotating pipe 409 is rotatably connected to one end of each bent connecting pipe 410. The outer wall of the rotating tube 409 is connected to a second external toothed ring 411. The outer wall of the rotating tube 409 is connected to two first nozzles 412. The outer wall of the first nozzles 412 is connected to multiple second nozzles 413. The top of the internal toothed ring 406 is connected to the top of the inner wall of the storage tank 2. The two sides of the internal toothed ring 406 are respectively engaged with one side of the two second external toothed rings 411. A through hole 9 is opened at the top of the inner wall of the storage tank 2. The inner wall of the through hole 9 is rotatably connected to the outer wall of the connecting tube 408. The top of the connecting tube 408 extends to the outside of the through hole 9, and the bottom of the connecting tube 408 extends into the storage tank 2. A support block 404 is connected to the outer wall of the water inlet pipe 403. The bottom of the support block 404 is connected to the top of the storage tank 2.

[0036] The specific implementation method is as follows: The output shaft of the motor 401 rotates, driving the gear 405 to rotate. When the gear 405 rotates, it meshes with the first external gear ring 407, causing the first external gear ring 407 to rotate. The rotation of the first external gear ring 407 drives the connecting pipe 408 to rotate. The rotation of the connecting pipe 408 drives the two bent connecting pipes 410 and multiple stirring blades 414 to rotate. The rotation of the stirring blades 414 can agitate the additives in the storage tank 2, thereby preventing the additives in the storage tank 2 from settling due to prolonged storage time, and thus improving the activity of the additives. The bending pipe 410 rotates, causing the second outer toothed ring 411 and the rotating pipe 409 to rotate around the inner toothed ring 406. The rotation of the rotating pipe 409 around the inner toothed ring 406 causes the first nozzle 412 and the second nozzle 413 to rotate around the inner toothed ring 406 along with the rotating pipe 409, so that the cleaning water sprayed from the first nozzle 412 and the second nozzle 413 can be sprayed more evenly. During the rotation of the second outer toothed ring 411 around the inner toothed ring 406, the second outer toothed ring 411 can rotate on its own axis by meshing with the inner toothed ring 406. The rotation of the rotating tube 409 causes the first nozzle 412 and the second nozzle 413 to rotate around the rotating tube 409 as the axis of rotation. This further makes the spraying of the first nozzle 412 and the second nozzle 413 more uniform, thereby improving the cleaning effect of the first nozzle 412 and the second nozzle 413 and making the cleaning of the storage tank 2 more convenient. At the same time, the second nozzle 413 can also clean the stirring blade 414. The first nozzles 412 on both sides are symmetrically distributed, so the first nozzles 412 on both sides... 2 can clean the first nozzle 412 opposite to each other. The cleaning water can enter from the inlet pipe 403, then enter the bend pipe 410 and the rotating pipe 409 through the connecting pipe 408, and finally spray out from the first nozzle 412 and the second nozzle 413. The wastewater after cleaning can be drawn out from the extraction pipe 8 by the water pump 6, and then discharged through the injection pipe 7. Similarly, the addition of additives is also achieved by the water pump 6, the extraction pipe 8 and the injection pipe 7. Rotating the threaded cover 1 can open the opening at the top of the storage tank 2, so that the additives can be added into the storage tank 2.

[0037] The shock absorption mechanism 5 includes multiple hinge seats 504 and two connecting blocks 505. The top of the hinge seat 504 is connected to the bottom of the fixed plate 3. A hinge rod 503 is hinged to one side of the hinge seat 504, and a first hinge block 502 is hinged to the other side of the hinge rod 503. A wheel 501 is rotatably connected to the other side of the first hinge block 502. Two second dampers 510 are connected to the top of the connecting block 505. One end of the moving part of the second damper 510 is connected to the bottom of the fixed plate 3. A second spring 511 is sleeved on the second damper 510. The two ends of the second spring 511 are connected to the top of the connecting block 505 and the bottom of the fixed plate 3, respectively. Both sides of the connecting block 505 are connected to a first damper 508. One end of the moving part of the first damper 508 is connected to a third hinge block 507. A second hinge block 506 is hinged to one side of the third hinge block 507. One side of the second hinge block 506 is in contact with one side of the hinge rod 503. A first spring 509 is sleeved on the first damper 508. The two ends of the first spring 509 are connected to one side of the third hinge block 507 and one side of the connecting block 505, respectively. A slider 512 is connected to one side of the second hinge block 506. A groove 513 is opened on one side of the hinge rod 503. The inner wall of the groove 513 is slidably connected to the outer wall of the slider 512.

[0038] The specific implementation method is as follows: When the wheel 501 is subjected to the force of a bumpy road surface, the wheel 501 can drive the hinge rod 503 to rotate around the hinge seat 504 through the first hinge block 502. Since the sliding groove 513 on one side of the hinge rod 503 and the slider 512 on one side of the second hinge block 506 are both T-shaped, during the rotation of the hinge rod 503 around the hinge seat 504, the sliding groove 513 can drive the second hinge block 506 to slide along one side of the hinge rod 503 and rotate around the third hinge block 507 through the slider 512, so that the third hinge block 507 drives the first damper 508 to extend and drive... The first spring 509 stretches to generate elastic force, while the third hinge block 507 can drive the connecting block 505 to move upward through the first damper 508. The upward movement of the connecting block 505 causes the second damper 510 to shorten and the second spring 511 to compress to generate elastic force. The combined force of the first damper 508, the first spring 509, the second damper 510, and the second spring 511 can buffer the impact of the wheel 501's bumps, thereby keeping the fixed plate 3 and the storage bin 2 stable and preventing the storage bin 2 from tipping over due to bumps, thus improving the overall stability of the device.

[0039] Working principle: When in use, start the motor 401. The output shaft of the motor 401 rotates, driving the gear 405 to rotate. The gear 405 meshes with the first external gear ring 407, driving the first external gear ring 407, the connecting pipe 408, and multiple stirring blades 414 to rotate. This allows the stirring blades 414 to agitate the additives in the storage tank 2. The rotation of the connecting pipe 408 drives the two bent connecting pipes 410 to rotate. The rotation of the bent connecting pipes 410 drives the second external gear ring 411, the rotating pipe 409, multiple first nozzles 412, and multiple second nozzles. 413 rotates around the inner gear ring 406, allowing the first nozzle 412 and the second nozzle 413 to evenly clean the inner wall of the storage tank 2. During the rotation of the second outer gear ring 411 around the inner gear ring 406, the second outer gear ring 411 can rotate by meshing with the inner gear ring 406, thus driving the rotating tube 409 to rotate. The rotation of the rotating tube 409 drives the first nozzle 412 and the second nozzle 413 to rotate around the rotating tube 409 as the axis of rotation, thereby further making the spraying more even. When the wheel 501 is subjected to... When subjected to the force of a bumpy road surface, wheel 501 can drive hinge rod 503 to rotate around hinge seat 504 via first hinge block 502. Since the sliding groove 513 on one side of hinge rod 503 and the slider 512 on one side of second hinge block 506 are both T-shaped, during the rotation of hinge rod 503 around hinge seat 504, sliding groove 513 can drive second hinge block 506 to slide along one side of hinge rod 503 and rotate around third hinge block 507 via slider 512, so that third hinge block 507 drives first damper 5 08 extends and causes the first spring 509 to stretch and generate elastic force. At the same time, the third hinge block 507 can drive the connecting block 505 to move upward through the first damper 508. The upward movement of the connecting block 505 causes the second damper 510 to shorten and causes the second spring 511 to compress and generate elastic force. The resistance of the first damper 508 and the second damper 510 and the elastic force of the first spring 509 and the second spring 511 can buffer the force of the wheel 501 bumping, so that the fixed plate 3 and the storage bucket 2 can remain stable.
