Description

Technical Field

[0001] This invention relates to the field of water supply and drainage pipeline technology, and in particular to a water supply and drainage pipeline that is easy to clear blockages. Background Technology

[0002] During construction, a large number of water supply and drainage pipes need to be installed. Although traditional water supply and drainage pipes have filters installed inside to filter impurities in the water, these filters need to be removed and cleaned after a period of use to prevent them from becoming clogged. However, cleaning traditional water supply and drainage pipes often requires manual disassembly, which is not only too troublesome but also not timely enough. Furthermore, the pipes cannot function properly during cleaning, thus reducing their practicality. Summary of the Invention

[0009] Furthermore, a transparent window is fixedly embedded inside the left end face of the collection box, and a filter screen plate is fixedly connected to the right side inside the collection box, with a filter screen fixedly embedded inside the upper part of the filter screen plate; when the collection box is installed to the lower end of the rectangular connecting pipe, the filter screen plate is slidably connected to the inner side of the U-shaped slide rail.

[0010] Furthermore, the scraping assembly includes a drive plate, a transverse guide rod, a first magnetic strip, a passive plate, a transverse slide rod, a second magnetic strip, and a rubber scraper sleeve.

[0013] Furthermore, when the crushing mechanism is in a rotating state, the actuating column drives the drive frame and the unclogging brush to move back and forth, and the bristles on the unclogging brush are in close contact with the left side of the filter screen. Beneficial effects

[0014] 1. This invention, through the cooperation of a drive box, transmission shaft, synchronous rotating shaft, and crushing mechanism, enables the water source to pass through the drive box. The hydraulically driven impeller drives the drive shaft, two drive pulleys, two first transmission pulleys, the transmission shaft, the second transmission pulley, the third transmission pulley, the synchronous rotating shaft, two first bevel gears, two second bevel gears, and two crushing rotating shafts to rotate. This causes the crushing rotating shafts to rotate the crushing blades at both ends. The rotating crushing blades then shred large debris in the water, preventing large debris from directly covering the filter screen surface and thus improving the reliability of the filter screen during use.

[0015] 2. This invention, through the cooperation of the crushing mechanism and the unblocking mechanism, enables the connecting ring to rotate during the rotation of the crushing blade. When the right connecting ring rotates, it drives the actuating column to rotate. The actuating column then drives the drive frame and the unblocking brush to move back and forth. The bristles on the unblocking brush are in close contact with the left side of the filter screen. The back-and-forth movement of the unblocking brush removes the debris attached to the left side of the filter screen, effectively preventing the filter screen from becoming clogged. This allows the water supply and drainage pipe to achieve automatic unblocking, eliminating the need for manual disassembly and unblocking. This is not only more convenient but also ensures more timely automatic unblocking.

[0016] 3. This invention, through the cooperation of tee fitting A, valve A, valve B, tee fitting B, valve C, and valve D, allows for the following: when it is necessary to clean the debris collected inside the collection box, first, valves A and C are manually closed, then the collection box at the bottom of the front square pipe can be removed for cleaning. After cleaning the debris inside the front collection box, valves A and C are manually opened again, then valves B and D are closed, and finally the collection box at the bottom of the rear square pipe can be removed for cleaning. Thus, when cleaning the debris collected inside the collection box, it is not necessary to close all valves, avoiding disruption to normal water supply and improving the practicality of this water supply and drainage pipeline.

[0017] 4. By setting up a scraping component, this invention allows the first magnetic strip to move back and forth along with the second magnetic strip by manually moving the drive plate when the right side of the transparent window is blocked by pollutants in the water. This, in turn, moves the rubber scraper sleeve back and forth, thus scraping away the pollutants blocking the right side of the transparent window. This makes it easier to see through the debris inside the collection box. Attached Figure Description

Through the cooperation of the drive box 4, the hydraulic drive impeller 403, the drive shaft 401 and the drive pulley 402, no additional motor is needed when driving the crushing mechanism 9 to operate, thus saving more energy. A first transmission pulley 501 is fixedly installed at both the front and rear ends of the transmission shaft 5, and a second transmission pulley 502 is fixedly installed on the outer middle side of the transmission shaft 5; the two first transmission pulleys 501 are connected to the two drive pulleys 402 respectively through two belts.

[0032] like Figure 1 , Figure 4 and Figure 8 As shown, a transparent window 701 is fixedly embedded inside the left end face of the collection box 7, and a filter screen plate 702 is fixedly connected to the right side inside the collection box 7, and a filter screen 703 is fixedly embedded inside the upper end of the filter screen plate 702; when the collection box 7 is installed to the lower end of the rectangular connecting pipe 201, the filter screen plate 702 is slidably connected to the inner side of the U-shaped slide rail 204, and the collection box 7 is used to collect the filtered debris.

[0033] like Figure 1As shown, the scraping assembly 8 includes a drive plate 801, a transverse guide rod 802, a first magnetic strip 803, a passive plate 804, a transverse slide rod 805, a second magnetic strip 806, and a rubber scraper sleeve 807. A transverse guide rod 802 is slidably connected to both the upper and lower ends of the drive plate 801, and the two transverse guide rods 802 are fixedly installed on the left end face of the collection box 7. A first magnetic strip 803 is provided on the right end face of the drive plate 801. A transverse slide rod 805 is slidably connected to both the upper and lower ends of the passive plate 804, and the two transverse guide rods 806 ... right end face of the collection box 7. The slide bar 805 is fixedly connected to the inside left side of the collection box 7. The passive plate 804 has a second magnetic strip 806 in the middle of the left side, and a rubber scraper sleeve 807 is sleeved on the outer left end of the second magnetic strip 806. The left side of the rubber scraper sleeve 807 is in close contact with the right side of the transparent window 701. With the setting of the scraping component 8, when the right side of the transparent window 701 is blocked by pollutants in the water, the pollutants blocked by the right side of the transparent window 701 can be scraped off, so that it is more intuitive to see through the debris inside the collection box 7.

[0034] like Figure 4 and Figure 10 As shown, the crushing mechanism 9 includes a crushing shaft 901, crushing blades 902, connecting rings 903, a second bevel gear 904, and a lever 905. The crushing shaft 901 is rotatably connected inside the square tube 2, and three crushing blades 902 are fixedly installed at both ends of the crushing shaft 901. A connecting ring 903 is fixedly connected to the outside of each of the three crushing blades 902 on the left and the three crushing blades 902 on the right, and the two connecting rings 903 are rotatably connected to the circular through holes on the two support plates 202 respectively. A lever 905 is fixedly connected to the right end face of the connecting ring 903 on the right. The second bevel gear 904 is installed on the outside of the crushing shaft 901, and the second bevel gear 904 meshes with the first bevel gear 602. The crushing mechanism 9 is used to crush large-volume debris in the water.

[0035] like Figure 10 As shown, the unblocking mechanism 10 includes an unblocking brush 1001, a support guide rod 1002, and a drive frame 1003. The unblocking brush 1001 is slidably connected to a support guide rod 1002 at both its upper and lower ends, and the two support guide rods 1002 are fixedly connected inside the square tube 2. The drive frame 1003 is fixedly connected to the left side of the unblocking brush 1001, and the inner side of the drive frame 1003 is slidably connected to the actuating column 905. When the crushing mechanism 9 is rotating, the actuating column 905 drives the drive frame 1003 and the unclogging brush 1001 to move back and forth. The bristles on the unclogging brush 1001 are in close contact with the left side of the filter screen 703. Through the setting of the unclogging mechanism 10, the debris attached to the left side of the filter screen 703 can be automatically removed, thereby effectively preventing the filter screen 703 from becoming clogged.

[0036] The specific usage and function of this embodiment: In the drainage process, the water source first enters the interior of the tee fitting A1 through the left inlet, then enters the interior of the two square pipes 2 through the two outlets on the right side of the tee fitting A1, and then is filtered by the filter screen 703 to remove impurities from the water. The filtered water source then enters the interior of the tee fitting B3 through the right outlet of the two square pipes 2, then enters the interior of the drive box 4 through the right outlet of the tee fitting B3, and finally is discharged through the right drain outlet of the drive box 4. When water flows through the drive box 4, the water flow impact causes the water-driven impeller 403 to rotate. The water-driven impeller 403 then drives the drive shaft 401 and two drive pulleys 402 to rotate. The two drive pulleys 402 then drive the two first transmission pulleys 501 and the drive shaft 5 via belts. The drive shaft 5 then drives the second transmission pulley 502 to rotate. The second transmission pulley 502 then drives the third transmission pulley 601, the synchronous shaft 6, and the two first bevel gears 602 via belts. The two first bevel gears 602 then drive the two second bevel gears 904 and the two crushing shafts 901 to rotate. This causes the crushing shafts 901 to rotate the crushing blades 902 at both ends. The rotating crushing blades 902 then shred large debris in the water, thus preventing large debris from directly covering the surface of the filter screen 703 and improving the reliability of the filter screen 703 during use. During the rotation of the breaker blade 902, the connecting ring 903 will rotate. When the right connecting ring 903 rotates, it will drive the actuating column 905 to rotate. The actuating column 905 will then drive the drive frame 1003 and the cleaning brush 1001 to move back and forth. The bristles on the cleaning brush 1001 will be in close contact with the left side of the filter screen 703. The cleaning brush 1001, which moves back and forth, can remove the debris attached to the left side of the filter screen 703, thereby effectively preventing the filter screen 703 from becoming clogged. This allows the water supply and drainage pipe to achieve automatic cleaning without the need for manual disassembly. When it is necessary to clean the debris collected inside the collection box 7, first manually close valves A101 and C301 to prevent water from flowing through the front square pipe 2. Then, remove the collection box 7 at the bottom of the front square pipe 2 for cleaning. After cleaning the debris inside the front collection box 7, manually open valves A101 and C301, and then close valves B102 and D302 to prevent water from flowing through the rear square pipe 2. Then, remove the collection box 7 at the bottom of the rear square pipe 2 for cleaning. Thus, when cleaning the debris collected inside the collection box 7, it is not necessary to close all valves, avoiding affecting the normal water supply operation and improving the practicality of this water supply and drainage pipeline.
