DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] A water supply and drainage anti-blocking device, such as Figure 1 , Figure 2As shown, it includes a box body 1, and the openings on the upper and lower sides of the box body 1 are connected and fixedly installed in sequence to form a drainage pipe. The upper tube 2 and the lower tube 3 are connected and connected through the box body 1, and the same inner tube 4 is slidably provided in the upper tube 2 and the lower tube 3. The outer periphery of the inner tube 4 is respectively in airtight sliding contact with the inner periphery of the upper tube 2 and the outer periphery of the lower tube 3. A strip slide groove is provided on the lower tube 3, and a slider is slidably installed in the strip slide groove. The slider is fixed on the inner tube 4, which can increase the stability of the inner tube 4 moving up and down in the lower tube 3. The cross sections of the box body 1, the upper tube 2, the lower tube 3 and the inner tube 4 are all circular. A filter screen plate 5 is fixedly provided on the upper end of the inner tube 4. The filter screen plate 5 is a plate with filtering holes. The filter screen plate 5 filters the inner tube 4. The upper port is sealed, and the filter screen plate 5 is an inverted cone, which is convenient for the filtered material on its top side to slide to the periphery. A partition 6 is fixedly provided in the inner tube 4, and a water storage chamber 7 is formed inside the inner tube 4 above the partition 6. A siphon tube 8 is provided in the water storage chamber 7. One end of the siphon tube 8 passes through the partition 6 and is located below the partition 6, and the other end is located above the partition 6. The inner tube 4 is connected to the drain pipe through a reset elastic member 9, and the reset elastic member 9 is a spring telescopic rod. One end of the spring telescopic rod is fixedly connected to the partition 6, and the other end is fixedly connected to the lower tube 3. A slag discharge port 10 is provided on the box body 1, and a sealing cover 11 is installed with the internal thread of the slag discharge port 10. The bottom side of the box body 1 is inclined, and the slag discharge port 10 is located on the lower side of the bottom side of the box body 1. The present invention has a simple structure and an ingenious design. The sewage is filtered through the filter mesh plate 5, and the filtered material remains on the top side of the filter mesh plate 5. The sewage is collected in the water storage chamber 7, thereby reducing the noise generated by the sewage frequently flowing through the sewer. The gravity of the sewage in the water storage chamber 7 is used to move the filter mesh plate 5 downward, so that the filtered material is discharged into the box body 1, reducing the influence of the filtered material on the filter mesh plate 5. Finally, the sewage in the water storage chamber 7 is discharged by the siphon 8, thereby completing the treatment of the sewage and reducing the blockage of the sewer. The present invention can meet actual needs and is suitable for promotion. When using the present invention, firstly, the drainage pipe of the device is connected to the sewer for discharging sewage, or the device is used alone, so that the sewage is passed into the upper pipe 2, and the sewage flows into the water storage chamber 7 through the filtering holes of the filter screen plate 5. The filtered matter in the sewage remains on the top side of the filter screen plate 5, and the sewage is preliminarily filtered. As the sewage gathers in the water storage chamber 7, the gravity of the sewage increases, so that the inner pipe 4 together with the filter screen plate 5 moves downward, and the reset elastic member 9 is compressed and stores energy; until the upper end of the inner pipe 4 moves out from the upper pipe 2, the filtered matter on the top side of the filter screen plate 5 slides toward the periphery and enters the box body 1, the filtered matter is cleaned, and the influence of the filtered matter on the filtering effect of the filter screen plate 5 is reduced. The filtered matter in the box body 1 can be cleaned through the slag discharge port 10; until the sewage in the water storage chamber 7 reaches the drainage water level of the siphon pipe 8, the sewage in the water storage chamber 7 is quickly discharged by the siphon pipe 8, and the inner pipe 4 moves upward and resets under the elastic thrust of the reset elastic member 9.

[0020] Specifically, if Figure 1 and Figure 2As shown, coaxial reserved holes are provided on the filter screen plate 5 and the partition plate 6 described in this embodiment, and the same vertical shaft 20 is rotatably installed in the reserved hole. The vertical shaft 20 is rotatably connected to the reserved hole by sealed bearings to reduce water leakage of the reserved hole. A spiral groove 21 is provided on the outer periphery of the vertical shaft 20. The spiral groove 21, the vertical shaft 20, the reserved hole, the filter screen plate 5 and the partition plate 6 are coaxially arranged. A sliding rod 22 is slidably provided in the spiral groove 21. The sliding rod 22 is fixed to the lower tube 3 through a connecting rod. A plurality of strip plates 23 are fixedly installed on the upper end of the vertical shaft 20, and the strip plates 23 are in sliding contact with the top side of the filter screen plate 5. When the inner tube 4 moves downward, the vertical shaft 20 is driven downward by the partition plate 6 and the filter screen plate 5, and the slide rod 22 slides along the spiral slide groove 21, so that the vertical shaft 20 rotates, and the vertical shaft 20 drives the strip plate 23 to rotate. The strip plate 23 can scrape and clean the filtered material on the top side of the filter screen plate 5, clean the filter holes, and make the filtered material fall to the periphery.

[0021] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, a brush is provided on one side of the strip plate 23 close to the filter screen plate 5. The brush can increase the cleaning effect of the strip plate 23 on the filter holes of the filter screen plate 5.

[0022] Further, such as Figure 1 and Figure 2 As shown, a crushing knife 40 is fixedly arranged on the filter screen plate 5 in this embodiment. When the vertical shaft 20 drives the strip plate 23 to rotate along the axis of the vertical shaft 20, the strip plate 23 moves in the gap between the crushing knife 40 and the filter screen plate 5, so that the strip plate 23 and the crushing knife 40 interact with each other, and can break the filter material with a larger volume into the filter material with a smaller volume. The broken filter material can pass through the filter hole of the filter screen plate 5 and enter the water storage chamber 7 for secondary filtration.

[0023] Furthermore, Figure 1 As shown, in this embodiment, a fine-pore filter screen plate 50 is fixedly installed in the lower tube 3, and a slag discharge hole 51 is provided on the side of the lower tube 3, and a sealing cover is provided in the slag discharge hole 51. The fine-pore filter screen plate 50 can perform secondary filtration on the sewage, filter out smaller filtrate, improve the accuracy of sewage filtration, and perform coarse filtration first and then fine filtration, thereby reducing the influence of large-volume filtrate on the fine-pore filter screen plate 50; the filtrate on the fine-pore filter screen plate 50 can be cleaned through the slag discharge hole 51.

[0024] Furthermore, Figure 1As shown, the lower end of the vertical shaft 20 in this embodiment is fixedly connected to the upper end of the telescopic shaft 60, the telescopic shaft 60 is coaxially arranged with the vertical shaft 20, the lower end of the telescopic shaft 60 is rotatably mounted on the lower tube 3 through the shaft seat 61, the lower end of the telescopic shaft 60 is fixedly mounted with a brush plate 62, and the brush of the brush plate 62 is in contact with the top side of the fine-pore filter screen 50. When the vertical shaft 20 moves up and down, the upper end of the telescopic shaft 60 is driven to telescope up and down; when the vertical shaft 20 rotates, the telescopic shaft 60 is driven to rotate, and the telescopic shaft 60 drives the brush plate 62 to rotate, and the brush of the brush plate 62 cleans the fine-pore filter screen 50 to reduce the blockage of the fine-pore filter screen 50.

[0025] Furthermore, Figure 1 As shown, the inner circumference of the inner tube 4 in this embodiment is fixedly installed with a coaxial spiral blade ring 70, and the spiral blade ring 70 is located below the lower end of the siphon tube 8. The sewage discharged from the siphon tube 8 falls on the spiral blade ring 70 and flows downward along the spiral blade ring 70, increasing the sewage flow path, slowing down the flow speed, and thus reducing the flow noise; at the same time, the sewage flows along the spiral blade ring 70, which can form a vortex impact, and the sewage flowing down can increase the impact effect on the fine-pore filter screen plate 50, so as to better clean the filter holes of the fine-pore filter screen plate 50; and as the height of the spiral blade ring 70 changes, the impact cleaning position of the fine-pore filter screen plate 50 changes continuously, cleaning a larger range.

[0026] Furthermore, Figure 1 As shown, the box body 1 of this embodiment is provided with a pressure relief hole 80, and a sealing cover is installed in the pressure relief hole 80. By opening the sealing cover in the pressure relief hole 80, the aggregation degree of the filtrate in the box body 1 can be observed, and the filtrate can be discharged through the slag discharge port 10.

[0027] Furthermore, Figure 1 As shown, the side wall of the lower tube 3 in this embodiment is provided with a plurality of filter holes 90 connected to the bottom of the box body 1, and the size of the filter holes 90 is the same as the filter hole size of the filter mesh plate 5. The sewage carried by the filtered material in the box body 1 flows back into the lower tube 3 through the filter holes 90.

[0028] Furthermore, Figure 1 and Figure 2As shown, in the embodiment, an elastic rubber tube 100 is slidably arranged in the upper tube 2, and the elastic rubber tube 100 is made of waterproof and corrosion-resistant materials. A fixed ring 101 and a movable ring 102 are fixedly arranged at both ends of the elastic rubber tube 100 in sequence. The fixed ring 101, the movable ring 102, and the elastic rubber tube 100 are respectively coaxially arranged with the upper tube 2, and the fixed ring 101 is fixed on the upper tube 2, and the movable ring 102 is fixedly connected with the vertical shaft 20 through a connecting rod. When the inner tube 4 drives the vertical shaft 20 to move downward, the movable ring 102 is driven downward by the connecting rod, and the elastic rubber tube 100 is stretched, and the dirt attached to its inner wall falls off. When the vertical shaft 20 rotates, the movable ring 102 is driven to rotate, so that the elastic rubber tube 100 is twisted, and the inner diameter of the elastic rubber tube 100 is retracted inward, reducing the sewage and the filtered material from continuing to be discharged downward, so that the discharged sewage is gathered in the middle of the filter screen plate 5, reducing the sewage from entering the box body 1, and reducing the large volume of filtered material from directly entering the box body 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
