Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sewage discharge, and more specifically, to a device for preventing drainage pipelines from being blocked. Background Art

[0002] The residential drainage system is an indispensable part of the building water supply and drainage system, and the smooth flow of the drainage system is closely related to our thousands of households. However, in actual daily life, due to various reasons such as construction and later management and operation, the indoor drainage system of the residence is often blocked. Although the drainage of the first floor is discharged separately, if the drainage riser of the second floor and above is blocked, the drainage will be poor or even backflow. If the blockage in the drainage riser cannot be removed in time, the sewage will gradually spread to the floor drain of the indoor bathroom and the sanitary ware of the toilet, which will bring a very bad experience to the residents. At present, the main way to clear the drainage pipe is to manually split it at the pipe connection, take out the blockage, and then reconnect the pipe. This method is prone to leakage when the pipe is not connected in place, and there are also problems such as incomplete emptying of the blockage and unsanitary conditions. Utility Model Content

[0003] An object of the present invention is to solve at least the above problems and to provide at least the advantages which will be described below.

[0017] Figure 1 This is a schematic diagram of the structure of the device for preventing drainage pipe blockage according to the utility model; DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 As shown, the utility model provides a device for preventing drainage pipes from being blocked, comprising:

[0021] A drainage pipe 1, which is arranged vertically;

[0022] The filter sheet 1 2 and the filter sheet 2 5 are arranged obliquely in the drainage pipe 1 and can rotate in the drainage pipe 1; the filter sheet 2 5 is arranged below the filter sheet 1 2 and remains stationary in the vertical direction; the center of the filter sheet 2 5 is fixedly connected with a center rod 3, and the other end of the center rod 3 is hinged to the center of the filter sheet 1 2;

[0023] A spring 4, two ends of which are fixedly connected to the filter plate 1 2 and the filter plate 2 5 respectively;

[0024] A sewage cleaning pipe 8 is connected to the drainage pipe 1, and the connecting port faces the lower end of the filter plate 2 5; a sewage collecting frame 9 is arranged in the sewage cleaning pipe 8 near the connecting port; the sewage collecting frame 9 has at least one opening, and the opening faces the connecting port; the end of the sewage cleaning pipe 8 away from the connecting port is detachably connected to a cover 7.

[0025] In this technical solution, during normal drainage, the water flow impacts the filter sheet 1 2 and the filter sheet 2 5, driving the two to rotate around the central rod 3; during the rotation process, the energy exchange with the working medium (gas, liquid, or a mixture of the two) is completed, ensuring that the drainage pipe 1 is unobstructed, and at the same time, impurities gradually accumulate on the filter sheet 1 2. When the impurities accumulate to a certain weight, they will overcome the elastic force of the spring 4, causing the filter sheet 1 to flip vertically, and then the impurities will fall from the filter sheet 1 2 to the filter sheet 2 5. Since the filter sheet 2 5 is tilted and the dirt collecting frame 9 is facing the lower end of the filter sheet 2 5, the impurities will be further pushed into the dirt collecting frame 9 under the action of gravity. It is only necessary to open the cover 7 regularly and pull out the dirt collecting frame 9 for cleaning to prevent the drainage pipe 1 from being blocked, without the need to disassemble the drainage pipe or manually clear the blockage. The vertical position of the filter plate 2 in the drainage pipe 1 can be kept stationary by setting a limit block on the inner wall of the drainage pipe 1 to support the filter plate 2 5 so that the filter plate 2 5 is inclined and does not slide down along the drainage pipe 1 while being able to rotate freely; a slot can also be set on the inner wall of the drainage pipe 1 to limit the filter plate 2 5 in the vertical direction without restricting its rotation.

[0026] In another embodiment, in order to ensure the strength of the filter plate 1 2 and the filter plate 2 5 so that they can bear a certain amount of impurities and meet the anti-corrosion requirements, the filter plate 1 2 and the filter plate 2 5 are stainless steel discs, and a plurality of filter holes are evenly opened on the stainless steel discs.

[0027] In another embodiment, the filter sheet 1 2 and the filter sheet 2 5 have an inclination angle of 30° to 40°, and the two are arranged in parallel. An appropriate inclination angle can prevent excessive accumulation of impurities on the filter sheet, which would affect normal drainage.

[0028] In another embodiment, the spring 4 is provided in plurality, and the plurality of springs 4 are symmetrically arranged about the center of the central rod. The spring 4 provides support for the filter sheet 1 2 during normal drainage, and quickly resets the filter sheet 1 2 after impurities fall from the filter sheet 1 2 onto the filter sheet 2 5.

[0029] In another embodiment, the sewage cleaning pipe 8 is a square pipe, and the size of the sewage collecting frame 9 matches the size of the sewage cleaning pipe 8, so that the sewage collecting frame 9 can be pushed to the connecting port along the inner wall of the sewage cleaning pipe 8. The outer size of the sewage collecting frame 9 matches the inner size of the sewage cleaning pipe 8, and the gap between the two is minimized as much as possible, so that impurities can directly enter the sewage collecting frame 9 from the filter plate 2 5. Preferably, the inner bottom surface of the sewage collecting frame 9 is not higher than the top surface of the lower end of the filter plate 2 5.

[0030] Furthermore, the cover 7 is fixedly connected to a connecting rod 6 on one side facing the sewage cleaning pipe 8, and the other end of the connecting rod 6 is connected to the sewage collecting frame 9. When the cover 7 is pulled out, the sewage collecting frame 9 can be pulled out at the same time, and the sewage collecting frame 9 can be pushed in through the cover 7, thereby avoiding manual contact with the sewage collecting frame 9, making the process of clearing the blockage more convenient and hygienic. The cover 7 can be connected to the sewage cleaning pipe 9 by means of a lock, a bolt or a threaded connection. When the cover 7 is threadedly connected to the sewage cleaning pipe 9, the connecting rod 6 is rotatably connected to the sewage collecting frame 9. A sealing gasket is also provided between the cover 7 and the sewage cleaning pipe 9.

[0031] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
