Description

Technical Field

[0001] The utility model relates to the technical field of building water supply and drainage, in particular to a building water supply and drainage anti-blocking device. Background Art

[0002] Water supply and drainage are divided into water supply system and drainage system. The water supply system draws natural water from rivers, lakes and reservoirs, and uses a series of physical and chemical methods to purify the water into tap water that meets the standards for production and domestic water use. The drainage system centrally treats the sewage and wastewater used in our production and life, and then discharges it into rivers, lakes and reservoirs after treatment.

[0003] When water flows in the water supply and drainage pipes, impurities are often mixed in the water, which will cause blockage in the pipes over time, resulting in water being unable to flow. For this reason, filters are often installed to collect and clean the debris in the pipes. Although filters are used for cleaning, large impurities in the water source are easily blocked on the surface of the filter, causing filtration to be easily blocked. In addition, when cleaning the impurities in the pipes, the entire device needs to be stopped, which is inconvenient for subsequent use. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 As shown, a building water supply and drainage anti-blocking device comprises a pipe body 1, a rotating rod 2 is arranged inside the pipe body 1, the right end of the rotating rod 2 is fixedly connected with an impeller 3, a plurality of blades 4 are fixed around the surface of the other end of the rotating rod 2, a connecting pipe 16 is fixedly connected to the left end of the pipe body 1 by bolts, a filter screen 17 is arranged inside the connecting pipe 16, a scraper 15 is fixedly connected to the left end of the rotating rod 2, the outer side of the scraper 15 is fitted with the right side of the filter screen 17, a discharge pipe 5 is connected to the bottom of the pipe body 1, a sealing cover 6 is connected to the internal thread of the bottom end of the discharge pipe 5, fixing plates 7 are fixedly connected to both sides of the front of the inner cavity of the pipe body 1, and a screw 8 is rotatably connected between the two fixing plates 7, a screw sleeve 9 is threadedly connected to the surface of the screw 8, a baffle 10 is fixedly connected to the bottom of the screw sleeve 9, and a force structure 11 for driving the screw 8 to rotate is arranged inside the pipe body 1.

[0024] The force-applying structure 11 includes a crank 111, a movable rod 112, a first bevel gear 113 and a second bevel gear 114. The movable rod 112 is rotatably connected to the inside of the surface of the pipe body 1, one end of the movable rod 112 is fixed to one side of the crank 111, and the other end of the movable rod 112 is fixed to one side of the first bevel gear 113. The other side of the first bevel gear 113 is meshed with the second bevel gear 114, and the inside of the second bevel gear 114 is fixed to the surface of the screw 8. In this way, when the screw 8 is driven to rotate, the crank 111 can be rotated, and the movable rod 112 and the first bevel gear 113 can be driven to rotate, and at the same time, the second bevel gear 114 can be driven to rotate, thereby driving the screw 8 to rotate.

[0025] Connecting plates 12 are fixedly connected to both sides of the rear inner cavity of the pipe body 1, and a fixing rod 13 is fixed between the two connecting plates 12. A movable sleeve 14 is movably connected to the surface of the fixing rod 13, and the bottom of the movable sleeve 14 is fixed to the top of the baffle 10, so that the baffle 10 can be auxiliary supported to facilitate its left and right movement.

[0026] The size of the baffle 10 is larger than the size of the aperture of the connection between the pipeline body 1 and the discharge pipe 5, so that before each discharge, the baffle 10 can be driven to block the connection between the pipeline body 1 and the discharge pipe 5.

[0027] A support plate 18 is fixed to the top of the inner cavity of the pipe body 1, and the inside of the support plate 18 is movably connected to the surface of the rotating rod 2, so that the rotating rod 2 can be auxiliary supported and its stability during rotation can be maintained.

[0028] A sealing gasket 19 is provided on the bottom surface of the baffle 10, and the sealing gasket 19 fits with the bottom of the inner cavity of the pipeline body 1, thereby increasing the sealing effect between the baffle 10 and the pipeline body 1 and preventing the baffle 10 from blocking the connection between the pipeline body 1 and the discharge pipe 5 and causing a large amount of water leakage.

[0029] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0030] Working principle: When in use, as the water source flows, the impeller 3 is driven to rotate, and the rotating rod 2 is driven to rotate together, and the blade 4 is also driven to rotate. The large impurities in the water source can be broken as the blade 4 rotates, so that they become smaller impurities and fall down to the inside of the discharge pipe 5. Then the water source will continue to be filtered through the filter 17. Since the filter 17 filters the water source many times, a large amount of impurity particles will be mixed on its surface. In order to avoid clogging, the rotation of the rotating rod 2 will also drive the scraper 15 to rotate, thereby scraping off the impurities on the surface of the filter 17, and the scraped impurities will also fall into the inside of the discharge pipe 5. In order to avoid the accumulation of impurities at the discharge pipe 5, The device has more substances and does not affect the normal use of the device. The crank 111 can be rotated to drive the movable rod 112 and the first bevel gear 113 to rotate, and at the same time drive the second bevel gear 114 and the screw 8 to rotate, thereby driving the screw sleeve 9 and the baffle 10 to move to the left, thereby blocking the connection between the pipeline body 1 and the discharge pipe 5. After that, the sealing cover 6 can be rotated to take out the impurities inside the discharge pipe 5. After the removal is completed, the baffle 10 can be driven back to the starting position by the force structure 11. At this time, impurities will fall from the top surface of the baffle 10. In this way, with the flow of water, the impurities dropped from the top of the baffle 10 will be transported to the left again and fall into the inside of the discharge pipe 5 again.
