[0043] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0044] This invention provides an integrated surface-to-solar chemical dosing device for oil and gas wellheads, such as... Figure 1-12 As shown, the device includes a drug storage unit 1 and a drug injection pump 2; it also includes a drug distribution unit 4, which is connected to the outlet of the drug injection pump 2, and has multiple individually openable and closable outlet pipes 402; the drug distribution unit 4 is equipped with an intercepting filter screen 405 for intercepting drug flocculation; a cleaning unit 8, which is located on the side of the intercepting filter screen 405 away from the outlet pipes 402, for cleaning the surface of the intercepting filter screen 405; a conveying unit 6, which is located below the cleaning unit 8, for collecting the flocculation cleaned from the intercepting filter screen 405, and the discharge position of the conveying unit 6 is connected to a drain bottom pipe 104 located below the drug storage unit 1, with a valve 105 installed below the drain bottom pipe 104; and a wind and solar power supply unit 5, which is installed behind the drug storage unit 1. Both the drug storage unit and the drug distribution unit are fixedly installed on the top of a support frame, which provides overall support and can fix the entire device to the ground at the oil and gas wellhead.

[0045] In specific implementation, by setting up a drug distribution mechanism 4 with multiple independently openable and closable drug outlet pipes 402, different drug outlet pipes 402 can dispense drugs independently, and the drug outlet pipes 402 can be connected to different drug addition positions at the oil and gas wellhead to achieve drug addition at different locations; furthermore, an intercepting filter screen 405 is set up in the drug distribution mechanism 4 to filter the drug and intercept the condensate in the drug. At the same time, the intercepting filter screen 405 is equipped with a cleaning mechanism 8 to clean the intercepting filter screen 405 and ensure smooth flow of the intercepting filter screen 405; furthermore, a conveying mechanism 6 is set up to convey the condensate cleaned from the intercepting filter screen 405, so that the condensate enters the drain bottom pipe 104 below the drug storage mechanism 1. When maintaining the drug storage mechanism 1, the drain bottom pipe 104 is opened to discharge the drug, and the collected condensate can be discharged together. No manual maintenance and cleaning of the drug distribution mechanism 4 is required.

[0046] The medicine storage mechanism 1 is used to store medicines and also has a stirring structure inside to ensure the uniformity of the medicines inside.

[0047] like Figure 2 As shown, the medicine storage tank 101 is used to store medicines. The mixing of the medicines is achieved by the first motor 103 driving the stirring shaft 106 to rotate inside the medicine storage tank 101. The stirring shaft 106 is used to stir the medicines inside the medicine storage tank 101 through the blades. The medicine inlet 102 is used to add medicines inside the medicine storage tank 101. The partition 107 is used to separate the internal space of the drain bottom pipe 104, forming an upper chamber and a lower chamber. The lower chamber is used to store the flocculated material conveyed to the drain bottom pipe 104 by the conveying mechanism 6. The upper chamber is connected to the injection pump 2 through the connecting pipe 10 to supply medicines to the injection pump 2. The partition 107 is used to prevent the flocculated material in the lower chamber from being sucked into the injection pump 2.

[0048] like Figure 1-11As shown, the dispensing mechanism 4 includes a rectangular box 401, a dispensing pipe 402, a dispensing pipe 403, a second motor 404, an intercepting filter screen 405, a cylinder 406, an end shaft 4061, a connecting port 407, and a port 408. The dispensing pipe 403 is fixedly connected to one side of the rectangular box 401. The end of the dispensing pipe 403 away from the rectangular box 401 is connected to the dispensing port of the dispensing pump 2. The dispensing pipe 402 is fixedly connected to the side of the rectangular box 401 away from the dispensing pipe 403, and one end of the dispensing pipe 402 extends into the rectangular box 401. The end of the dispensing pipe 402 inside the rectangular box 401 is fitted against the cylindrical surface of the cylinder 406 to seal the end of the dispensing pipe 402. The cylindrical surface of the cylinder 406 has multiple connecting holes that communicate with the interior of the cylinder 406, and multiple connecting ports 407 correspond one-to-one with multiple medicine outlet tubes 402. The multiple connecting ports 407 are spirally distributed on the cylindrical surface of the cylinder 406. One end of the cylinder 406 is closed, and the other end is provided with a port 408 that communicates with the interior of the cylinder 406. An end shaft 4061 is fixedly connected to the closed end of the cylinder 406, and the end shaft 4061 is coaxially arranged with the cylinder 406. The second motor 404 is fixedly installed on the outer wall of the rectangular box 401, and the output shaft end of the second motor 404 is fixedly connected to the end shaft 4061. The intercepting filter screen 405 is installed inside the rectangular box 401.

[0049] By controlling the opening and closing of the inlet pipe 403, the liquid medicine enters the dispensing mechanism 4. Different inlet pipes 403 can be used to dispense the medicine at different locations. The medicine drawn by the dispensing pump 2 enters the rectangular box 401 through the inlet pipe 403, is further filtered by the intercepting filter screen 405, and is then discharged from the outlet pipe 402.

[0050] The opening and closing control of the medicine dispensing tube 402 is achieved by the second motor 404 driving the cylinder 406 to rotate, so that the individual medicine dispensing tube 402 is aligned with its corresponding connecting port 407, allowing the medicine dispensing tube 402 to dispense medicine. The medicine enters the cylinder 406 through the port 408 and then enters the medicine dispensing tube 402 through the connecting port 407, thus realizing the medicine dispensing process.

[0051] like Figure 4-5As shown, the cleaning mechanism 8 includes a scraper 801, a connecting shaft 802, and an elastic connector. One end of the connecting shaft 802 is connected to the scraper 801 through the elastic connector, and one side of the scraper 801 is attached to one side wall of the intercepting filter screen 405. The other end of the connecting shaft 802 is connected to a transmission mechanism 7, and the transmission mechanism 7 is connected to the end shaft 4061. The elastic connector includes a guide rod 803, a perforated plate 804, and a spring 805. The perforated plate 804 is fixedly connected to the connecting shaft 802. A guide hole is provided on the perforated plate 804. The guide rod 803 is connected to the guide hole with a clearance fit, and one end of the guide rod 803 is fixedly connected to the scraper 801. The spring 805 is sleeved on the guide rod 803, and both ends of the spring 805 are fixedly connected to the scraper 801 and the perforated plate 804, respectively.

[0052] The cleaning mechanism 8, driven by the transmission mechanism 7, cleans the surface of the filter screen 405, scraping off the condensed lint from top to bottom. Specifically, the transmission mechanism 7 drives the elastic connector and the scraper 801 to move up and down, while the scraper 801 provides pressure through the elastic connector, pressing it firmly onto the filter screen 405 to ensure a good fit. The spring 805 is in a compressed state, providing pressure to the scraper 801.

[0053] like Figure 4 and Figure 8 As shown, the transmission mechanism 7 includes a vertical drive unit, a third pulley 703, a fourth pulley 704, a shaft 705, and a second synchronous belt 706. The shaft 705 is connected to the vertical drive unit. The fourth pulley 704 is fixedly sleeved onto the shaft 705, and the third pulley 703 is fixedly sleeved onto the end shaft 4061. The second synchronous belt 706 is wound between the third pulley 703 and the fourth pulley 704. The diameter of the third pulley 703 is larger than the diameter of the fourth pulley 704. The vertical drive unit includes a housing 701, an outlet 702, a connecting rod 707, a slider 708, a slide rail 709, a guide sleeve 710, and a guide post 711. The housing 701 is fixedly installed inside the rectangular box 401. On the wall, connecting rod 707, slider 708, slide rail 709, guide sleeve 710 and guide post 711 are all set inside housing 701. One end of connecting rod 707 is fixedly connected to one end of shaft 705, and shaft 705 is rotatably installed with housing 701. The other end of connecting rod 707 is rotatably connected to slider 708, and slider 708 is slidably connected to slide rail 709. Guide sleeve 710 is fixedly connected to slide rail 709. Guide post 711 is connected to guide sleeve 710 and fixedly installed inside housing 701. An outlet 702 for inserting connecting shaft 802 is provided on one side wall of housing 701, and outlet 702 is vertically arranged. One end of connecting shaft 802 is fixedly connected to slide rail 709.

[0054] The transmission mechanism 7 drives the cleaning mechanism 8, allowing the cleaning mechanism 8 to be driven by the second motor 404, eliminating the need for an additional power source. The vertical drive unit converts the rotational motion of the power source into vertical movement to drive the cleaning mechanism 8.

[0055] Specifically, when the second motor 404 drives the cylinder 406 to rotate, changing the opening and closing state of the dispensing tube 402, it simultaneously drives the third pulley 703 to rotate. Through the transmission of the second synchronous belt 706, the fourth pulley 704 rotates, and the connecting rod 707 rotates through the shaft 705. When the connecting rod 707 rotates, it pushes the slide rail 709 and the guide sleeve 710 together along the length direction of the guide post 711 through the slider 708, which drives the connecting shaft 802 to move up and down.

[0056] like Figure 2-4 As shown, the conveying mechanism 6 includes a collection cover 602, which is installed at the bottom of the rectangular box 401. The top of the collection cover 602 is provided with a feed inlet 604 that communicates with the bottom of the rectangular box 401. The feed inlet 604 is located at the bottom of the intercepting filter 405. A ramp strip 9 for docking the intercepting filter 405 with the feed inlet 604 is fixedly connected below the intercepting filter 405.

[0057] The conveying mechanism also includes a conveying pipe 601 and a second pulley 609; one end of the conveying pipe 601 is connected to the collection hood 602, and the other end of the conveying pipe 601 is connected to the drain bottom pipe 104, and the conveying pipe 601 is connected to the lower cavity of the drain bottom pipe 104; a spiral conveying shaft 603 is provided inside the conveying pipe 601, the spiral conveying shaft 603 extends into the collection hood 602, the spiral conveying shaft 603 is rotatably connected to the collection hood 602, and one end of the spiral conveying shaft 603 is fixedly connected to a round shaft located outside the collection hood 602, and the round shaft is sleeved with a A second bevel gear 611 is meshed with a first bevel gear 610. The first bevel gear is connected to a rotating shaft 605. A fixed frame 606 is connected to the bottom of the rectangular box 401. The rotating shaft 605 is rotatably connected to the fixed frame 606. A first pulley 607 is sleeved on the rotating shaft 605. A second pulley 609 is fixedly installed on a third pulley 703. The second pulley 609 and the third pulley 703 are coaxially arranged. A first synchronous belt 608 is wound between the first pulley 607 and the second pulley 609.

[0058] The conveying mechanism 6 is used to convey the condensed flocculation under cleaning. The inclined bar 9 provides guidance for the scraper 801 to scrape the flocculation, so that the flocculation can enter the collection hood 602 through the feed inlet 604. The scraper 801 adopts an elastic connection to ensure that it fits in close contact with the inclined bar 9 when moving.

[0059] The conveying mechanism 6 operates by intercepting the condensed flocculation on the filter screen 405 and feeding it into the collection hood 602 through the feed inlet 604. By driving the screw conveyor shaft 603 to rotate, the flocculation is conveyed through the conveying pipe 601 into the lower cavity of the drain bottom pipe 104. The rotation of the screw conveyor shaft 603 drives the second pulley 609 to rotate through the third pulley 703, and the first pulley 607 to rotate through the first synchronous belt 608. In turn, the first bevel gear 610 is driven to rotate through the rotating shaft 605. The first bevel gear 610 and the second bevel gear 611 mesh and drive the screw conveyor shaft 603 to rotate.

[0060] Through the design of the transmission structure described above, the conveying mechanism 6 is driven by the second motor, so that the conveying mechanism 6 does not need to be equipped with an additional power source.

[0061] like Figure 1 As shown, the wind and solar power supply unit 5 includes a solar power generation device 501, a wind power generation device 502, a battery pack, and a power controller; both the solar power generation device 501 and the wind power generation device 502 are electrically connected to the battery pack, and the battery pack is connected to the power controller.

[0069] Example 4

[0070] This embodiment uses the integrated surface-to-solar chemical dosing device for oil and gas wellheads provided in the above embodiment. It employs three outlet pipes 402, resulting in three connecting ports 407 on the cylinder 406. Rotating the cylinder 406 by 120° allows one connecting port 407 to connect with one outlet pipe 402, while the other outlet pipes 402 are blocked. The transmission ratio between the third pulley 703 and the fourth pulley 704 is 1:6. For every 60° rotation of the third pulley 703, the fourth pulley 704 rotates 360°. After chemical dosing, a 60° rotation ensures that all connecting ports 407 are not aligned with the outlet pipes 402, at which point the scraper is driven to move to the top of the interceptor filter screen 405.

[0071] The integrated surface-wind-solar chemical dosing device for oil and gas wellheads provided by this invention can transport the condensate cleaned from the intercepting filter screen, allowing the condensate to enter the drain pipe below the chemical storage mechanism. When performing maintenance on the chemical storage mechanism, the drain pipe can be opened to discharge the chemical, and the collected condensate can be discharged together. No manual maintenance or cleaning of the chemical dispensing mechanism is required.
