[0016] 1. The present invention provides a fluid filter drain valve. After draining is completed, the handle is rotated in the opposite direction to move the sealing block downward to seal the valve body. During this process, water is supplied to the inside of the water inlet pipe, and the water enters the sealing sleeve through the water inlet pipe, and then is transported to the rotating disk through the water trough on the water delivery pipe, and then is transported to the inside of the scraper through the connecting pipe, and finally discharged through the water outlet hole. At this time, the water flow will impact and clean the inner wall of the groove, and in this process, the blade is impacted by the water flow, so that the blade drives the fixed block to rotate, and then drives the connecting shaft to rotate, and the rotation of the connecting shaft The two sets of rotating discs rotate in opposite directions, so the two sets of rotating discs will drive the two sets of scrapers to scrape along the inner wall of the groove, and the inner wall of the groove can be cleaned with the help of water spray, and the cleaned mud and sand impurities are cleaned to the bottom of the groove and collected by the collecting component, thereby avoiding the obstruction of the sealing block by the mud and sand, and then through the action of the cleaning component and the collecting component, it is convenient to clean the mud and sand on the inner wall of the groove and collect it through the action of the collecting component, thereby solving the problem of mud and sand accumulating at the bottom of the groove and affecting the sealing performance of the sealing block in the prior art.

[0017] 2. The fluid filter drain valve provided by the present invention will drive the torsion spring to contract during the rotation of the connecting shaft.

Therefore, the action of the connecting shaft will reset the two sets of rotating disks, and then reset the scraper.

[0018] 3. The present invention provides a fluid filter drain valve. When cleaning the fluid filter, the threaded column is rotated by turning the handle, and the prismatic column is moved by the threaded connection between the threaded column and the prismatic column, and the collection box is driven to move by the movement of the prismatic column, which facilitates the flushing and cleaning of the mud and sand in the collection box. In addition, when cleaning the collection box, the sealing sleeve seals both ends of the groove, and the collection box is installed at the bottom end of the groove. Therefore, after the collection box is removed, the sealing of the valve body as a whole is not affected. Therefore, the cleaning of the collection box needs to be carried out after the valve body is sealed, and the collection box cannot be cleaned during the drainage process.

The rotating disk 10 is connected to a connecting pipe 11, and the connecting pipe 11 is connected to a scraper 12 that is fitted with the inner wall of the groove 2. The scraper 12 is hollow and connected to the connecting pipe 11. A plurality of water outlet holes 13 are provided on the scraper 12. The cleaning component scrapes off impurities on the groove 2 through the action of the scraper 12 and sprays water in conjunction with the water outlet holes 13 to facilitate scraping mud and sand impurities into the collecting component for collection. The cooperation of the cleaning component and the collecting component facilitates cleaning of the mud and sand and collecting the cleaned mud and sand, thereby avoiding mud and sand remaining in the groove 2 and affecting the sealing of the valve body 1.

[0033] The cleaning assembly includes a water inlet pipe 14 that is slidably connected to the column 4. The top of the water inlet pipe 14 extends to the outside of the column 4 and is fixedly connected to a connecting piece 15. The other end of the water inlet pipe 14 is connected to the interior of the sealing sleeve 3. Both ends of the sealing sleeve 3 are fixedly connected to sealing pieces 16. A water pipe 17 that is connected to the rotating disk 10 is installed between the two groups of sealing pieces 16. Several groups of water troughs 18 are opened on the water pipe 17, and a water pipe 17 that is connected to the rotating disk 10 is installed in the sealing sleeve 3. The rotating member 19 is used to drive the two groups of rotating disks 10 to rotate and make the rotation directions of the two groups of rotating disks 10 opposite. The water flow is transported to the inside of the sealing sleeve 3 through the water inlet pipe 14, and then enters the inside of the two groups of rotating disks 10 through the action of the water delivery pipe 17. It is then transported to the scraper 12 through the connecting pipe 11 and finally discharged through the water outlet 13 to clean the inner wall of the groove 2. At the same time, the water flow can be used as power to make the rotating member 19 run, drive the two groups of rotating disks 10 to rotate in opposite directions, and then make the two groups of scrapers 12 rotate in opposite directions.

[0034] The rotating member 19 includes a connecting shaft 20 rotatably connected to the sealing plate 16, one end of the connecting shaft 20 is fixedly connected to the rotating disk 10, and the other end of the connecting shaft 20 is connected to a reversing member 25 connected to another group of rotating disks 10, and the connecting shaft 20 is fixedly connected to a fixed block 21 installed at a position below the water inlet pipe 14, and the outer side surface of the fixed block 21 is fixedly connected to multiple groups of connecting columns 22, and the connecting columns 22 are fixedly connected to blades 23, and a reset member 24 is installed between the connecting shaft 20 and the sealing plate 16. The blades 23 are impacted by the action of water flow, so that the blades 23 drive the fixed block 21 to rotate, and then drive the connecting shaft 20 to rotate, and the rotating disk 10 is driven to rotate by the rotation of the connecting shaft 20, while the other group of rotating disks 10 rotates in the opposite direction through the action of the reversing member 25.

[0035] The reversing member 25 includes a second spur gear 26 fixedly connected to the connecting shaft 20, a third spur gear 27 is meshed on the outer side of the second spur gear 26, the axis of the third spur gear 27 is fixedly connected to a rotating column 28 rotatably connected to the sealing plate 16, and a gear ring 29 is meshed on the outer side of the third spur gear 27, and a fixing ring 30 fixedly connected to another group of rotating disks 10 is fixedly connected to the gear ring 29. When the connecting shaft 20 rotates, the second spur gear 26 will also be driven to rotate. Therefore, the third spur gear 27 is driven to rotate by the action of the second spur gear 26, and then the gear ring 29 drives the fixing ring 30 to rotate through the rotation of the third spur gear 27, thereby driving the other group of rotating disks 10 to rotate.

[0036] The reset member 24 includes a connecting block 31 fixedly connected to the connecting shaft 20, a torsion spring 32 fixedly connected to the connecting block 31, and an end of the torsion spring 32 fixedly connected to a fixing column 33 fixedly connected to the sealing sheet 16. The setting of the torsion spring 32 can reset the two groups of scrapers 12 after the water flow stops, avoiding the cleaning of the groove 2 when the valve is opened next time.

[0037] After the sewage is discharged, the first flat gear 6 is driven to rotate by rotating the handle 8, and the sealing sleeve 3 is driven to move upward by the column 4. At this time, the valve body 1 is opened to discharge sewage. In the process of sewage discharge, the mud and sand impurities in the sewage will be adsorbed on the inner wall of the groove 2. In order to ensure its sealing, the mud and sand need to be cleaned. Therefore, after the sewage is discharged, the first flat gear 6 is driven to move downward by reversing the handle 8, so that the sealing sleeve 3 is reset to seal the valve body 1. In this process, water is transported to the inside of the sealing sleeve 3 through the action of the water inlet pipe 14, and then the water enters the inside of the sealing sleeve 3 through the action of the water inlet pipe 14, and then is transported to the rotating disk 10 through the water delivery trough 18 on the water delivery pipe 17, and then is transported to the inside of the scraper 12 through the connecting pipe 11, and finally is discharged through the action of the water outlet 13. At this time, the water flow will impact and clean the inner wall of the groove 2. In this process, the blade 23 is impacted by the action of the water flow, so that the blade 23 drives the fixed block 21 to rotate. The rotation of the connecting shaft 20 drives the rotating disk 10 to rotate. In addition, the rotation of the connecting shaft 20 will also drive the second flat gear 26 to rotate. Therefore, the third flat gear 27 is rotated by the action of the second flat gear 26. The rotation of the third flat gear 27 causes the gear ring 29 to drive the fixed ring 30 to rotate, thereby driving the other set of rotating disks 10 to rotate. Since the rotation direction of the second flat gear 26 is opposite to the rotation direction of the third flat gear 27 and the gear ring 29, and the second flat gear 26 is consistent with the rotation direction of the connecting shaft 20, the two sets of rotating disks 10 will rotate in opposite directions, thereby causing the two sets of scrapers 12 to rotate in opposite directions, thereby causing the scrapers 12 to scrape along the inner wall of the groove. Through the action of rotation, the two sets of scrapers 12 are finally all vertically downward and in contact with each other. At this time, the cleaning is completed and the water flow is stopped. Then, through the action of the two sets of scrapers 12, all the mud and sand are scraped to the bottom of the groove 2 and collected by the collection assembly, thereby preventing the mud and sand from affecting the sealing sleeve 3.

[0038] In addition, during the rotation of the connecting shaft 20, the torsion spring 32 will be driven to contract. Therefore, after the water flow stops, the torsion spring 32 will automatically reset after losing the torque. Therefore, the action of the torsion spring 32 will drive the connecting shaft 20 to reset. Therefore, the action of the connecting shaft 20 will reset the two sets of rotating disks 10, and then reset the scraper 12.

[0039] Example 2

[0040] See also Figure 9 and Figure 10This embodiment further illustrates the first embodiment. The collecting assembly shown in the figure includes a collecting box 34 slidably connected to the valve body 1. The bottom end of the collecting box 34 is fixedly connected to a prismatic column 35. The outer side surface of the prismatic column 35 is slidably connected to a fixing frame 38 fixedly connected to the valve body 1, and a fixing sleeve 37 is fixedly connected to the fixing frame 38. A threaded column 36 threadedly connected to the prismatic column 35 is rotatably connected to the fixing sleeve 37, and a turning handle 39 is fixedly connected to the end of the threaded column 36.

[0041] In this embodiment, it is necessary to regularly clean the mud and sand in the collection box 34 to prevent excessive mud and sand inside the collection box 34 from affecting the sealing effect of the sealing sleeve 3 on the valve body 1. When cleaning it, the threaded column 36 is rotated by turning the handle 39, and then the prismatic column 35 is moved through the threaded connection between the threaded column 36 and the prismatic column 35, and then the collection box 34 is driven to move by the movement of the prismatic column 35, which makes it easy to flush and clean the mud and sand in the collection box 34.

[0042] In addition, when cleaning the collection box 34, the sealing sleeve 3 seals both ends of the groove 2, and the collection box 34 is installed at the bottom end of the groove 2. Therefore, after the collection box 34 is removed, it does not affect the overall sealing of the valve body 1. Therefore, the cleaning of the collection box 34 needs to be carried out after the valve body 1 is sealed, and the collection box 34 cannot be cleaned during the sewage discharge process.

[0043] Example 3

[0044] See also Figure 1 and Figure 7 The present embodiment further explains the first and second embodiments. The outer sides of the turning handle 39 and the handle 8 are both provided with anti-slip sleeves to increase the friction during rotation, thereby facilitating the rotation of the handle 8 and the turning handle 39. The two ends of the collecting box 34 are not closed, which is beneficial for cleaning the mud and sand inside the collecting box 34. There are two groups of torsion springs 32, which are symmetrically installed on the connecting shaft 20. The setting of the two groups of torsion springs 32 increases the torque, thereby facilitating the reset of the connecting shaft 20, so that the two groups of rotating disks 10 drive the two groups of scrapers 12 to reset. The end of the scraper 12 is conical, and the conical surface position of the scraper 12 is in contact with the inner wall of the groove 2, which is beneficial for scraping the inner wall of the groove 2, thereby facilitating the cleaning of mud and sand impurities adsorbed on the inner wall of the groove 2.
