Description

Technical Field

[0001] The utility model relates to the field of application of water supply and drainage pipelines, and more particularly to a water seal bend and a pipeline system. Background Art

[0002] With the rapid economic development, the drainage requirements of various systems vary greatly, and more and more functions are required for various drainage pipe fittings. Especially in places such as bathrooms, balconies, kitchens, and sinks, water seal bends are often needed to prevent odors and the discharge of sundries. However, the water seal bends are often blocked, resulting in problems such as drainage backflow and odor return. Existing water seal bend pipe fittings are difficult to solve this problem.

[0003] In view of this, it is particularly necessary to provide a pipe fitting that can reduce pipeline blockage or can be dredged in time after pipeline blockage. Summary of the Utility Model

[0007] The cutting device includes a cutting head extending into the bending part from the installation port and a power source capable of driving the cutting head to rotate. A second connection part capable of sealing the installation port is sleeved on the power source, and the first connection part and the second connection part are fixedly connected.

[0008] In an optional embodiment, the installation port is located outside the bending part of the bending part.

[0009] In an optional embodiment, the first connection part is a first flange ring, the second connection part is a second flange ring, and the first flange ring and the second flange ring are fixed by bolts.

[0030] First Embodiment

[0031] Please refer to Figure 1 and Figure 2 In this embodiment, a water seal is provided, which includes a bent portion 100. An installation opening for installing a cutting device is provided on the bent portion 100, and a first connection portion 200 is provided on the installation opening;

[0032] The cutting device includes a cutting head 400 extending into the bent portion 100 from the installation opening and a power source 500 capable of driving the cutting head 400 to rotate. A second connection portion 300 capable of sealing the installation opening is sleeved on the power source 500, and the first connection portion 200 and the second connection portion 300 are fixedly connected.

[0033] In the embodiment of the present utility model, a cutting device is installed on the bent portion 100 of the water seal. When sundries accumulate in the water seal and there is a tendency of blockage in the pipeline, the cutting device can be turned on to cut the sundries that cause blockage in the pipeline. As the cutting progresses, the blockage gradually decreases. When the blockage is small enough, it can move forward under the drive of the water flow in the pipeline, thereby dredging the blocked area. Similarly, even if the pipeline is already blocked, the cutting device can be turned on to dredge the blocked area.

[0034] In this embodiment, there are no restrictions on the shape, size, etc. of the installation opening, as long as the cutting head 400 can extend into the bent portion 100, and at the same time, the power source 500 can partially pass through the installation opening to achieve the purpose of driving the cutting head 400 to rotate.

[0035] In some embodiments, the installation opening is located outside the bent portion 100.

[0036] Normally, the outside of the water seal is located below, where sundries are more likely to accumulate and the pipeline is more likely to be blocked. Therefore, the installation opening is set below. In addition, when some high-density or relatively important sundries block the pipeline and cannot be cut by the cutting device or need to be recovered and cannot be cut by the cutting device, the installation opening can also be opened to take out the required sundries.

[0037] In some embodiments, the first connection portion 200 is a first flange ring, the second connection portion 300 is a second flange ring, and the first flange ring and the second flange ring are fixed by bolts.

[0038] In some embodiments, the first connection portion 200 and the second connection portion 300 can also adopt an internal and external thread structure to achieve their threaded connection. In this embodiment, flange connection is more convenient, labor-saving, and there is no problem that the threaded connection becomes stuck after long-term use and is difficult to disassemble.

[0039] In some embodiments, a sealing ring 600 is further disposed between the end face of the second flange ring close to the cutting head 400 and the mounting opening.

[0040] The presence of the sealing ring 600 can prevent water leakage. In this embodiment, the sealing ring 600 can be a rubber ring. In order to prevent the position of the sealing ring 600 from shifting during the assembly of the device, in some embodiments, an annular groove can also be provided on the second flange ring to position the sealing ring 600.

[0041] In some embodiments, the power source 500 includes a motor, and the cutting head 400 is mounted on the output shaft of the motor.

[0042] In some embodiments, the cutting head 400 can be mounted on a rotating shaft. A handwheel is provided at one end of the rotating shaft passing through the bending portion 100. The cutting head 400 is driven to rotate by rotating the handwheel. However, this method is inconvenient to operate and time-consuming for dredging the pipeline. Therefore, in this embodiment, the motor is used to drive the cutting head 400. When there is a tendency of blockage or after blockage occurs, the motor can be turned on, and then turned off after dredging.

[0043] For the installation method of the output shaft and the cutting head, clamping or any other method that can stably connect the two in the prior art can be adopted.

[0044] It should be noted that in some embodiments, in order to reduce the water in the pipeline from entering the motor through the output shaft after long-term use, waterproof work needs to be done. Specific measures can be selected in the prior art, such as selecting a motor with better waterproof performance; however, using an ordinary motor can also achieve the effect of dredging the pipeline, but the service life is slightly reduced.

[0045] In some embodiments, two or more cutting teeth 410 are provided on the cutting head 400, and the two or more cutting teeth 410 are evenly distributed circumferentially on the cutting head 400, as Figure 3 shown.

[0046] The two or more cutting teeth 410 can increase the cutting efficiency on the one hand and are beneficial to improving the service life of the cutting head 400 on the other hand.

[0047] Generally, considering the cutting efficiency, service life and cost, it is sufficient to provide 3 - 5 cutting teeth 410 on the cutting head 400.

[0048] In some embodiments, the distance between the cutting teeth 410 and the axis of the cutting head 400 gradually increases in the direction away from the cutting head 400. On the one hand, this can increase the area covered by the cutting head 400. On the other hand, during the cutting process, a force can be applied to the blockage in the direction of the axis of the cutting head 400, which is beneficial to "pull" the blockage around the coverage area into the coverage area for cutting, thereby facilitating the improvement of the dredging efficiency.

[0049] In some embodiments, each of the cutting teeth 410 has more than two cutting edges. One of the cutting edges is arranged along the tangent direction of the rotation of the cutting tooth 410 along the cutting head 400, and the other cutting edges form an acute angle with the tangent direction of the rotation of the cutting tooth 410 along the cutting head 400. This is beneficial to improving the dredging efficiency.

[0050] In some embodiments, it further includes a timer, the timer is connected to a controller, and the controller is also in signal connection with the power source 500.

[0051] The timer is connected to the controller of the power source, enabling the power source to start and stop regularly, reducing or alleviating pipeline blockage.
