[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0032] See also Figure 1 - Fig. 9 As shown, this embodiment provides an anti-blocking device for building water supply and drainage, including a drainage channel 1, and also including:

[0033] The drainage frame 2 is fixedly connected to the bottom of the drainage channel 1, and the contact surface between the drainage frame 2 and the drainage channel 1 is provided with drainage holes 3 at equal intervals;

[0034] The drain cover 4 is located above the drain channel 1, and the front and rear surfaces of the drain cover 4 are symmetrically provided with mounting grooves for mounting the connecting block 33;

[0035] An installation assembly is disposed inside the plurality of connection blocks 33 and is used to fix the drain cover 4 to the drain channel 1;

[0036] The filter assembly is located above the drain cover 4 and is used to filter impurities in the water;

[0037] The connection frame 15 is located inside the drainage channel 1. A cleaning scraper 19 is provided outside the connection frame 15. The front and rear surfaces of the connection frame 15 are fixedly connected with mounting plates 16. The bottoms of the two mounting plates 16 are symmetrically provided with receiving grooves 21.

[0038] The adjustment components are respectively arranged on the front and rear surfaces of the drain channel 1 and are used to adjust the horizontal positions of the connection frame 15 and the cleaning scraper 19.

[0039] The fixing assembly is disposed inside the plurality of receiving grooves 21 and is used for disassembling and installing the connection frame 15 and the cleaning blade 19 .

[0040] The above working principle: when it is necessary to discharge the water in the city, it is only necessary to install the drain 1 first. When the drain 1 is installed to the designated position, the drain cover 4 and the drain 1 are fixed by installing the assembly. At this time, the water in the city will fall into the interior of the drain 1 through the drain cover 4, and then be discharged to the interior of the drain frame 2 through the drain hole 3, and then be discharged through the drain frame 2, thereby achieving the purpose of discharging the water in the city. Since the water in the city may contain impurities such as garbage, the impurities such as garbage may cause blockage to the drain cover 4 and the interior of the drain 1. Therefore, the filter assembly can effectively intercept and filter the impurities such as garbage, thereby preventing the garbage from passing through the drain. The cover 4 falls into the interior of the drain 1. When the inner wall of the drain 1 needs to be cleaned, the adjusting component starts to operate. At this time, the adjusting component will drive the connecting frame 15 and the cleaning scraper 19 to move synchronously. During the movement of the cleaning scraper 19, the inner wall of the drain 1 can be effectively cleaned. When the cleaning scraper 19 needs to be disassembled, replaced or cleaned, the connecting frame 15 and the cleaning scraper 19 can be easily disassembled through the fixing component, thereby facilitating the staff to disassemble, replace or clean the cleaning scraper 19 without the need for the staff to use tools such as bolts, which effectively improves the disassembly and assembly efficiency of the cleaning scraper 19, reduces the workload of the staff, and saves time and effort.

[0041] In order to facilitate the staff to install the drain cover 4 and the drain channel 1, the installation component includes a first telescopic rod 30 fixedly connected to the inside of the plurality of connecting blocks 33, the telescopic ends of the plurality of first telescopic rods 30 are fixedly connected to the arc-shaped clamping blocks 31, the outsides of the plurality of first telescopic rods 30 are sleeved with reset springs 32, the plurality of reset springs 32 are abutted between the arc-shaped clamping blocks 31 and the connecting blocks 33, the outsides of the plurality of connecting blocks 33 are provided with guide grooves for the movement of the arc-shaped clamping blocks 31, the front end surface and the rear end surface of the drain channel 1 are provided with guide grooves for the movement of the arc-shaped clamping blocks 31, and when the drain cover 4 and the drain channel 1 need to be installed, it is only necessary to plug the drain cover 4 into the drain channel 1. The drain cover 4 will move inside the drain channel 1, and the connecting block 33 will drive the arc block 31 to move synchronously. When the connecting block 33 drives the arc block 31 to move to the inside of the drain channel 1, the arc block 31 will be squeezed. At this time, the arc block 31 will squeeze the first telescopic rod 30 and the reset spring 32 synchronously. When the connecting block 33 drives the arc block 31 to move to the guide grooves on the front and rear surfaces of the drain channel 1, the reset spring 32 is reset, driving the arc block 31 to move synchronously. When the arc block 31 is inserted into the guide grooves on the front and rear surfaces of the drain channel 1, the drain cover 4 can be fixed to the drain channel 1.

[0042] Considering that the water in the external environment may contain impurities such as garbage, which may cause the drain cover 4 and the interior of the drain channel 1 to be blocked, the filter assembly includes a filter plate 5 located above the drain cover 4, and a bottom plate 9 is symmetrically arranged at the bottom of the filter plate 5.

During the movement of the movable plate 26, the resistance spring 27 will be squeezed, and the movable plate 26 will also drive the plug rod 29 to move synchronously. At this time, the bottom plate 9 is plugged into the inside of the mounting frame 8, and then the pull plate is released. At this time, the resistance spring 27 is reset, driving the movable plate 26 to move synchronously, and the movable plate 26 drives the plug rod 29 to move synchronously. When the plug rod 29 is plugged into the guide grooves on both sides of the outer wall of the bottom plate 9, the bottom plate 9 can be fixed to the mounting frame 8.

The extrusion is performed synchronously, and then the mounting plate 16 is plugged into the interior of the fixed frame 17. At this time, the mounting plate 16 will drive the fixing rod 23 to move synchronously. When the mounting plate 16 drives the fixing rod 23 to move into the guide grooves on both sides of the outer wall of the fixing frame 17, the connecting spring 24 is reset, driving the fixing rod 23 to move synchronously.
