Description

Technical Field

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

[0002] Water supply and drainage refers to the urban water supply system, drainage system and building water supply and drainage, referred to as water supply and drainage. The water supply project is a project that supplies living and production water for residents and factories, mines and transportation enterprises, as well as water for fire fighting and road greening. The water supply and drainage system consists of water supply sources, water intake structures, raw water pipelines, water treatment plants and water supply networks. It has the function of collecting and transporting raw water and improving water quality.

[0003] An existing patent (publication number: CN216379799U) discloses a water supply and drainage anti-clogging device for construction projects, comprising a crushing barrel, a drive motor, a drive shaft, and crushing blades disposed on the crushing barrel, a cleaning brush disposed on the drive shaft, an inlet pipe and an outlet pipe disposed on the sides of the crushing barrel, a filter screen disposed at one end of the outlet pipe, a valve disposed on the inlet pipe, a storage barrel disposed below the crushing barrel, a storage net disposed within the storage barrel, a pull rod disposed within the storage net, the pull rod being hingedly connected to the storage net, a long-bristled brush disposed on the pull rod, and an observation window disposed on the side of the storage barrel. The crushing blade disposed at one end of the drive shaft facilitates crushing of wastewater, preventing it from clogging the drainpipe. The cleaning brush cooperates with the filter screen to facilitate repeated scrubbing of the filter screen, preventing it from clogging the mesh. The rotational engagement between the long-bristled brush and the storage net facilitates quick and convenient cleaning of the storage net later.

[0004] In the above patented technology, large impurities are cleaned by setting a crushing blade, and the filter cover is cleaned by a cleaning brush to avoid pipe blockage. However, it is unable to promptly determine whether a blockage has occurred inside the water supply and drainage pipe. When the water supply and drainage pipe is found to be blocked, sewage cannot be discharged, resulting in sewage backflow, which is inconvenient to clean and causes a certain degree of pollution. Therefore, a water supply and drainage device for construction projects is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0026] Please refer to Figure 1-Figure 5 The utility model provides a technical solution: a water supply and drainage device for construction engineering, comprising a first drainage pipe 1, a second drainage pipe 3 and a filter box 2 located between the first drainage pipe 1 and the second drainage pipe 3, the top outer surface of the first drainage pipe 1 is fixedly connected to a convergence tube 4, the top outer surface of the convergence tube 4 is movably inserted with an insertion rod 5, the bottom outer surface of the insertion rod 5 is fixedly connected to a spring 6, the bottom outer surface of the spring 6 is fixedly connected to a floating plate 7, the top outer surface of the insertion rod 5 is fixedly connected to an extrusion block 8, the top outer surface of the convergence tube 4 is fixedly connected to a sleeve 9, the top inner surface of the sleeve 9 is installed with a switch button 10, the top outer surface of the sleeve 9 is installed with an audible and visual alarm 11, the switch button 10 and the audible and visual alarm are connected. The alarm 11 is electrically connected. In this embodiment, when the inside of the filter box 2 is clogged, the sewage is discharged slowly. When there is a lot of sewage, the sewage enters the converging tube 4. The sewage causes the float 7 to move upward, causing the insertion rod 5 to move upward, and the insertion rod 5 drives the extrusion block 8 to move upward. When the extrusion block 8 contacts the switch button 10, the sound and light alarm 11 sounds an alarm, thereby reminding the staff to dredge the pipeline in time. By setting the spring 6, when the staff fails to dredge the pipeline in time, the water level of the water flow in the converging tube 4 will rise. When the extrusion block 8 contacts the switch button 10, as the water level rises, the spring 6 is deformed, providing a channel for the rising water level to prevent sewage from flowing back.

[0027] A U-shaped tube 20 is fixedly connected between the first drain pipe 1 and the second drain pipe 3. A first valve 21 is provided at one end of the first drain pipe 1 close to the filter box 2, a second valve 22 is provided at one end of the second drain pipe 3 close to the filter box 2, and a third valve 23 is provided at one end of the U-shaped tube 20 close to the first drain pipe 1. In this embodiment, when it is necessary to replace the filter screen 18 inside the filter box 2 or to inspect and repair its internal parts, the first valve 21 and the second valve 22 are closed, and the third valve 23 is opened to allow water to enter through the U-shaped tube 20 and be discharged through the second drain pipe 3. The filter box 2 can then be disassembled without affecting the use of the device. In this way, the filter box 2 can be disassembled without affecting the normal use of the drainage device.

[0028] The inner surface of the filter box 2 is provided with a mounting frame 17, and a filter screen 18 is provided inside the mounting frame 17. The top inner surface of the filter box 2 is fixedly connected with a vertical plate, and the outer surface of the vertical plate is rotatably penetrated by a rotating shaft 13. The outer surface of the rotating shaft 13 near the filter screen 18 is fixedly connected with a cleaning brush 16, and the cleaning brush 16 is movably fitted with the outer surface of the filter screen 18. In this embodiment, when the rotating shaft 13 rotates, it drives the cleaning brush 16 to rotate, and the surface of the filter screen 18 is cleaned by the cleaning brush 16, and impurities on the surface of the filter screen 18 are removed.

[0029] A motor 12 is fixedly mounted on the top outer surface of the filter box 2. A driving bevel gear 14 is fixedly sleeved on the output end of the motor 12. A driven bevel gear 15 is fixedly sleeved on the outer surface of the rotating shaft 13. The driving bevel gear 14 is movably engaged with the outer surface of the driven bevel gear 15. In this embodiment, the motor 12 drives the driving bevel gear 14 to rotate, driving the driven bevel gear 15 to rotate the rotating shaft 13.

[0030] A cross is fixedly connected to the inner surface of the filter box 2, and the rotating shaft 13 is rotatably connected to the outer surface of the cross. In this embodiment, by setting the cross, larger impurities such as plastic bags are intercepted. When drainage is not performed, the impurities fall under the action of their own gravity.

[0031] The top outer surface of the mounting frame 17 is fixedly connected with a mounting plate 19, and the mounting frame 17 is movably inserted into the inner surface of the filter box 2. The mounting plate 19 is fixedly connected to the top outer surface of the filter box 2 by bolts. In this embodiment, the mounting plate 19 can be easily removed by removing the bolts, thereby pulling the mounting plate 19 to drive the mounting frame 17 so that the filter screen 18 can be taken out and replaced.

[0032] The bottom outer surface of the filter box 2 is fixedly connected to two receiving boxes 24, and the two receiving boxes 24 are fixedly connected to the bottom outer surface of the filter box 2 by bolts. In this embodiment, the two receiving boxes 24 are respectively located below the cross and the mounting frame 17, so that impurities can fall into the interior of the mounting frame 17, and the receiving boxes 24 can be disassembled by unscrewing the bolts, thereby cleaning the impurities inside the receiving boxes 24.

[0033] The left and right outer surfaces of the filter box 2 are fixedly connected with telescopic tubes, and the outer surfaces of the two telescopic tubes opposite to the first drain pipe 1 and the second drain pipe 3 are provided with flanges. In this embodiment, the telescopic tubes are connected to the first drain pipe 1 and the second drain pipe 3 through the flanges, thereby connecting the filter box 2 to the first drain pipe 1 and the second drain pipe 3. By providing the telescopic tubes, the telescopic tubes can be extended and retracted when the filter box 2 is disassembled, providing a channel for the filter box 2.

[0034] A first sealing gasket is provided at the connection between the mounting plate 19 and the filter box 2 . In this embodiment, the first sealing gasket is provided to increase the sealing performance of the connection between the mounting plate 19 and the filter box 2 .

[0035] The connection between the two receiving boxes 24 and the filter box 2 is provided with a second sealing gasket. In this embodiment, the sealing performance of the connection between the receiving box 24 and the filter box 2 is increased by providing the second sealing gasket.

[0036] Working principle: When the utility model is in use, water flows through the first drain pipe 1 and filters the water when passing through the filter box 2. When the inside of the filter box 2 is blocked, the sewage is discharged slowly. When there is a lot of sewage, the sewage enters the gathering tube 4, and the sewage makes the float plate 7 move upward, making the rod 5 move upward, and the rod 5 drives the squeezing block 8 to move upward. When the squeezing block 8 contacts the switch button 10, the sound and light alarm 11 sounds an alarm, thereby reminding the staff to dredge the pipeline in time. When dredging, the motor 12 is turned on, and the motor 12 drives the rotating shaft 13 to rotate, driving the active bevel gear 14 to rotate. The driving bevel gear 14 drives the driven bevel gear 15 to rotate so that the rotating shaft 13 rotates, thereby driving the cleaning brush 16 to rotate, and the surface of the filter screen 18 is cleaned by the cleaning brush 16, and the impurities on the surface of the filter screen 18 are cleared and fall into the interior of the receiving box 24 for collection. When it is necessary to replace the filter screen 18 inside the filter box 2 or to overhaul its internal parts, the first valve 21 and the second valve 22 are closed, and the third valve 23 is opened to allow water to enter through the U-shaped tube 20 and be discharged through the second drain pipe 3, and then the filter box 2 is disassembled without affecting the use of the device.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
