[0022] A method for using a drainage blind pipe to prevent crystallization blockage comprises the following steps:

[0023] S1. When in use, first rotate the adjustment rod inside the adjustment tube, so that the lower part of the adjustment rod with the disc rises inside the blind tube body. At this time, the disc brings the lower parts of the four X-shaped hinged rods to rise synchronously, so that the upper and lower ends of the X-shaped hinged rods tend to move relative to each other. Then, the end of the X-shaped hinged rod close to the blind tube body moves toward the inner wall of the blind tube body with the hinged scraper.

[0024] S2. During the movement of the scraper, the scraper releases the overlap limit with the side wall of the disc, and the torsion spring elastically recovers to rotate the U-shaped connecting block and the scraper on the surface of the support rod, so that the T-shaped pin between the U-shaped connecting block and the scraper rotates to the insertion hole position of the side wall of the U-shaped bracket. When the T-shaped pin is inserted into the inside of the insertion hole, the scraper is locked in an inclined state;

[0025] S3, then rotate the adjustment tube and move it along the axis direction of the filter plate, so that the adjustment tube drives the X-shaped hinged rod and the defined scraper to rotate synchronously to scrape and clean the inner wall of the blind tube body. When the interior of the blind tube body is cleaned, rotate the adjustment rod in the opposite direction to reset the X-shaped hinged rod and move the hinged scraper toward the adjustment tube. During this process, the lower part of the X-shaped hinged rod drives the scraper bar to slide on the surface of the support rod through the pull rope, and the scraper bar scrapes and cleans the surface of the scraper. At the same time, the top of the scraper in an inclined state cleans the bottom of the filter plate through the bristles.

[0026] S4. When the scraper moves to the bottom position of the cone sleeve, the pressure rod on the top of the scraper is compressed and moves the movable sleeve downward. At this time, the inclined groove on the surface of the movable sleeve slides with the T-shaped pin, so that the T-shaped pin is released from the plug-in hole. As the scraper continues to move, when the scraper moves to the side wall of the disc, the four retracted scrapers fit the surface of the disc to wrap the disc in a ring shape and restrict it to the lower position of the adjusting tube.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, by using the blind tube body, the adjusting mechanism, the cleaning mechanism and other components in coordination, the adjusting mechanism drives the cleaning mechanism to operate, so that the cleaning mechanism can effectively clean the bottom of the filter plate while cleaning the crystals on the inner wall of the blind tube body, thereby improving the convenience of use.

[0029] In the present invention, by using the scraper, scraper strip and support rod together, when the four scrapers are gathered together and reset, the scraper strip will slide on the surface of the support rod to automatically clean the scraper surface after cleaning, thereby improving the use effect of the scraper.

[0030] In the present invention, through the coordinated use of components such as scrapers, discs and regulating tubes, when the scrapers are not in use, the four scrapers gather in a ring shape toward the regulating tube, and the side walls of the scrapers overlap with the surface of the disc to wrap the lower part of the regulating tube, effectively reducing the pollution of sewage to the X-shaped hinged rod position and improving the service life. At the same time, the gathered scrapers reduce the interference caused by the blind pipe body when transporting sewage. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figures 1 to 12 The present invention provides a technical solution: a drainage blind pipe for preventing crystallization blockage, comprising a blind pipe body 1, a connecting sleeve 2 is movably sleeved at the lower part of the blind pipe body 1, a filter sleeve 3 is threadedly connected at the upper part of the blind pipe body 1, a filter plate 4 is fixedly connected at the middle part of the filter sleeve 3, and the bottom of the filter plate 4 is overlapped at the top of the blind pipe body 1.

[0048] The adjustment mechanism 6 includes an adjustment rod 601, which is threadedly connected to the inside of the adjustment tube 5. The bottom of the adjustment rod 601 penetrates the adjustment tube 5 and extends to the inside of the blind tube body 1. The bottom of the adjustment rod 601 is fixedly connected with a disc 602, and the top of the disc 602 is fixedly connected with four main hinge blocks 603 at equal intervals along the circumference. The four main hinge blocks 603 correspond to four X-shaped hinge rods 7 one by one, and the lower part of the X-shaped hinge rod 7 away from the side of the blind tube body 1 is hingedly installed with the corresponding main hinge block 603. It should be noted that when the adjustment rod 601 moves up and down inside the blind tube body 1 with the disc 602, the disc 602 deforms with the hinged X-shaped hinge rod 7, and the cleaning mechanism 8 is adjusted.

[0049] In this embodiment, Figures 1 to 12 As shown, the adjusting rod 601 is composed of a rotating rod, a bearing and a vertical rod. The surface of the rotating rod is provided with an external thread. The bearing is fixedly connected between the rotating rod and the vertical rod. The disc 602 is fixedly connected to the bottom of the vertical rod.

[0050] A thread groove is provided on the upper portion of the inner wall of the adjusting tube 5 , and the rotating rod is threadably connected to the thread groove via an external thread.

[0051] A slide groove is vertically provided on the inner wall of the adjusting tube 5, and sliders are fixedly connected to both sides of the vertical rod, and the two sliders are slidably connected to the inside of the two slide grooves. It should be noted that: through the bearing setting, the rotating rod will not rotate with the vertical rod and the rotating disk during rotation, avoiding interference; and the slide groove cooperates with the slider to ensure that the vertical rod and the disk 602 can move vertically stably.

[0052] The lower part of the adjusting tube 5 is hinged with four secondary hinge blocks at equal intervals along the circumference, and the upper part of the X-shaped hinge rod 7 away from the side of the blind tube body 1 is hingedly installed with the corresponding secondary hinge blocks.

[0053] In this embodiment, Figures 1 to 12As shown, the cleaning mechanism 8 includes a cone sleeve 801 , which is fixedly connected to the bottom of the filter plate 4 , and the regulating tube 5 is movably inserted in the middle of the cone sleeve 801 .

[0054] A U-shaped bracket 802 is hingedly connected to the upper part of the side of the X-shaped hinge rod 7 away from the adjustment tube 5, waist-shaped grooves 803 are provided on both sides of the lower part of the U-shaped bracket 802, the lower part of the side of the X-shaped hinge rod 7 away from the adjustment tube 5 is hinged between the two waist-shaped grooves 803, and a support rod 804 is vertically fixedly connected to the side of the U-shaped bracket 802 away from the X-shaped hinge rod 7. It should be noted that a hinge pin is slidably connected between the two waist-shaped grooves 803, and the lower part of the X-shaped hinge rod 7 is hingedly installed at the middle position of the hinge pin.

[0055] The upper and lower parts of the support rod 804 are both hinged with U-shaped connection blocks 805, and a torsion spring 806 is fixedly connected between the inner wall of the U-shaped connection block 805 and the surface of the support rod 804. A scraper 807 is fixedly connected between the side walls of the two U-shaped connection blocks 805, and the side wall of the scraper 807 overlaps the inner wall of the blind tube body 1. The top of the scraper 807 is fixedly connected with bristles 808 that match the filter plate 4. It should be noted that: the U-shaped bracket 802 and the support rod 804 will not rotate under the restriction of the X-shaped hinge rod 7. At this time, under the action of the torsion spring 806, the U-shaped connection block 805 can rotate on the surface of the support rod 804 with the unrestricted scraper 807 to adjust the angle of the scraper 807; when the scraper 807 is in an inclined state, it is convenient to scrape the inner wall of the blind tube body 1, and the scraper 807 in an inclined state can effectively clean the bottom of the filter plate 4 through the bristles 808.

[0056] A moving groove 809 is vertically provided in the middle of the inner wall of the scraper 807, and a moving sleeve 810 is vertically slidably connected inside the moving groove 809. A pressure rod 811 matching with the cone sleeve 801 is fixedly connected to the top of the moving sleeve 810, and the upper part of the pressure rod 811 is movably inserted in the top of the scraper 807, and a pressing spring 812 is fixedly connected between the bottom of the moving sleeve 810 and the inner bottom surface of the moving groove 809. It should be noted that when the scraper 807 moves toward the adjustment tube 5 with the pressure rod 811, the pressure rod 811 will first contact with the cone sleeve 801, and then the scraper 807 will contact with the side wall of the disc 602 at the lower position of the adjustment tube 5, ensuring that the scraper 807 is unlocked before deflection.

[0057] The middle part of the movable sleeve 810 is symmetrically provided with through grooves 813, and the two through grooves 813 correspond one to one with the two ends of the U-shaped connecting block 805. The inner wall of the through groove 813 is symmetrically provided with oblique grooves 814, and a T-shaped pin 815 is slidably connected between the two oblique grooves 814. One end of the T-shaped pin 815 passes through the scraper 807 and is movably inserted in the middle part of the corresponding U-shaped connecting block 805. Both ends of the U-shaped bracket 802 are provided with sockets 816, and the two T-shaped pins 815 are movably inserted into the inside of the two sockets 816 respectively.

[0058] The surface of the support rod 804 is movably sleeved with a scraper strip 817, the side wall of the scraper strip 817 overlaps the side wall of the scraper plate 807, and a pull rope 818 is fixedly connected between the surface of the scraper strip 817 and the lower part of the adjacent X-shaped hinge rod 7. It should be noted that: the scraper strip 817 is rotatably connected to the support rod 804, so that the scraper plate 807 can deflect synchronously with the scraper strip 817 during deflection to avoid interference.

[0059] In this embodiment, Figures 1 to 12 As shown, a movable groove is provided inside the U-shaped connecting block 805 , one end of the torsion spring 806 is fixedly connected to the inner wall of the movable groove, and the other end of the torsion spring 806 is fixedly connected to the surface of the support rod 804 .

[0060] In this embodiment, Figures 1 to 12 As shown, an arc-shaped positioning groove is provided on one side of the upper and lower parts of the U-shaped bracket 802, and a positioning pin is fixedly connected to the side walls of the two U-shaped connecting blocks 805, and the two positioning pins are respectively slidably connected to the inside of the two arc-shaped positioning grooves. It should be noted that: by sliding with the positioning pin and the arc-shaped positioning groove, it is ensured that the deflection angle of the scraper 807 can effectively scrape the inner wall of the blind tube body 1.

[0061] In this embodiment, Figures 1 to 12 As shown, the pull rope 818 is replaced by a hinged rod. It should be noted that the hinged rod can increase the service life.

[0062] A rectangular groove is provided on one side of the U-shaped bracket 802 near the scraper 807, and the pull rope 818 is movably inserted in the rectangular groove. It should be noted that when the lower part of the X-shaped hinge rod 7 slides up and down inside the waist-shaped groove 803, the X-shaped hinge rod 7 slides up and down synchronously with the scraper strip 817 on the surface of the support rod 804 through the pull rope 818, so that the scraper strip 817 cleans the surface of the scraper 807.

[0063] In this embodiment, Figures 1 to 12As shown, the top of the scraper 807 is arranged on the same horizontal line as the bottom of the cone sleeve 801. It should be noted that when the four scrapers 807 are folded, they can overlap with the side wall of the disc 602, and the side walls of the four scrapers 807 are overlapped together in a ring shape, end to end, and when not in use, the scrapers 807, the regulating pipe 5 and the disc 602 are wrapped to reduce the pollution of the X-shaped hinge rod 7 by sewage.

[0064] In this embodiment, Figures 1 to 12 As shown, a method for using a drainage blind pipe to prevent crystallization blockage comprises the following steps:

[0065] S1. When in use, first rotate the adjusting rod 601 inside the adjusting tube 5, so that the lower part of the adjusting rod 601 with the disc 602 rises inside the blind tube body 1, and at this time, the disc 602 and the lower parts of the four X-shaped hinged rods 7 rise synchronously, so that the upper and lower ends of the X-shaped hinged rods 7 tend to move relative to each other, and then the end of the X-shaped hinged rod 7 close to the blind tube body 1 moves toward the inner wall of the blind tube body 1 with the hinged scraper 807;

[0066] S2. During the movement of the scraper 807, the scraper 807 releases the overlap limit with the side wall of the disc 602, and the torsion spring 806 elastically recovers to rotate the U-shaped connecting block 805 and the scraper 807 on the surface of the support rod 804, so that the T-shaped pin 815 between the U-shaped connecting block 805 and the scraper 807 rotates to the position of the insertion hole 816 on the side wall of the U-shaped bracket 802. When the T-shaped pin 815 is inserted into the inside of the insertion hole 816, the scraper 807 is locked in an inclined state;

[0067] S3, then rotate the adjusting tube 5 and move it along the axis direction of the filter plate 4, so that the adjusting tube 5 rotates synchronously with the X-shaped hinged rod 7 and the defined scraper 807 to scrape and clean the inner wall of the blind tube body 1. When the interior of the blind tube body 1 is cleaned, the adjusting rod 601 is rotated in the opposite direction to reset the X-shaped hinged rod 7 and move the hinged scraper 807 toward the adjusting tube 5. During this process, the lower part of the X-shaped hinged rod 7 slides on the surface of the support rod 804 with the scraper bar 817 through the pull rope 818, and the scraper bar 817 scrapes and cleans the surface of the scraper 807. At the same time, the top of the scraper 807 in the inclined state cleans the bottom of the filter plate 4 through the bristles 808;

[0068] S4. When the scraper 807 moves to the bottom position of the cone sleeve 801, the pressure rod 811 on the top of the scraper 807 is compressed and moves the movable sleeve 810 downward. At this time, the inclined groove 814 on the surface of the movable sleeve 810 cooperates with the T-shaped latch 815 to slide, so that the T-shaped latch 815 is released from the plug-in hole 816. As the scraper 807 continues to move, when the scraper 807 moves to the side wall position of the disc 602, the four retracted scrapers 807 fit the surface of the disc 602 to wrap the disc 602 in a ring shape and restrict it to the lower position of the regulating tube 5.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.

8. A method for using a drainage blind pipe to prevent crystallization blockage according to claim 7, comprising the following steps: S1. When in use, firstly, the adjusting rod (601) inside the adjusting tube (5) is rotated, so that the lower part of the adjusting rod (601) with the disc (602) rises inside the blind tube body (1), and at this time, the disc (602) and the lower parts of the four X-shaped hinged rods (7) rise synchronously, so that the upper and lower ends of the X-shaped hinged rods (7) tend to move relative to each other, and then the end of the X-shaped hinged rod (7) close to the blind tube body (1) moves toward the inner wall of the blind tube body (1) with the hinged scraper (807); S2. During the movement of the scraper (807), the scraper (807) releases the overlap limit with the side wall of the disc (602), and the torsion spring (806) elastically recovers to cause the U-shaped connecting block (805) and the scraper (807) to rotate on the surface of the support rod (804), so that the T-shaped latch (815) between the U-shaped connecting block (805) and the scraper (807) rotates to the position of the insertion hole (816) on the side wall of the U-shaped bracket (802). When the T-shaped latch (815) is inserted into the inside of the insertion hole (816), the scraper (807) is locked in an inclined state; S3, then rotating the adjustment tube (5) and moving it along the axis direction of the filter plate (4), so that the adjustment tube (5) and the X-shaped hinged rod (7) and the defined scraper (807) rotate synchronously to scrape and clean the inner wall of the blind tube body (1); when the interior of the blind tube body (1) is cleaned, the adjustment rod (601) is rotated in the opposite direction to reset the X-shaped hinged rod (7) and move the hinged scraper (807) in the direction of the adjustment tube (5); during this process, the lower part of the X-shaped hinged rod (7) slides on the surface of the support rod (804) with the scraper bar (817) through the pull rope (818), and the scraper bar (817) scrapes and cleans the surface of the scraper (807), and at the same time, the top of the scraper (807) in the inclined state cleans the bottom of the filter plate (4) through the brush (808); S4. When the scraper (807) moves to the bottom position of the cone sleeve (801), the pressure rod (811) on the top of the scraper (807) is pressed and moves the movable sleeve (810) downward. At this time, the inclined groove (814) on the surface of the movable sleeve (810) and the T-shaped latch (815) slide in cooperation, so that the T-shaped latch (815) is released from the plug hole (816). As the scraper (807) continues to move, when the scraper (807) moves to the side wall position of the disc (602), the four retracted scrapers (807) fit the surface of the disc (602) to wrap the disc (602) in a ring shape and restrict it to the lower position of the regulating tube (5).
