[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] Reference Figure 1-8 , a building water supply and drainage device, comprising a main pipe 1 connected to a drainage pipeline, a secondary pipe 2 is fixedly arranged in the middle of the main pipe 1, and a second through hole 14 for water circulation is opened on the secondary pipe 2;
[0029] A filter screen 7 is detachably connected in the secondary pipe 2, and a filter screen inlet 8 of the filter screen 7 faces the water inlet of the main pipe 1;
[0030] A drum mechanism is also provided in the secondary pipeline 2 , and two water passages are provided on the drum mechanism for controlling whether water passes through the filter screen 7 .
[0031] In a specific embodiment of the utility model, the main pipe 1 is divided into two ends, namely, a water inlet and a water outlet. The main pipe 1 is used to connect the drainage pipeline, and the filter screen 7 in the auxiliary pipe 2 is used to filter the discharged sewage to avoid blockage caused by excessive accumulation of solid dirt in the drainage pipe.
[0032] The drum mechanism with two water passages can be used to change the position through which water passes when passing through the auxiliary pipe 2. One of the water passages passes through the filter screen 7. This is the normal state in which the filter screen 7 is used to filter sewage. When the filter screen 7 is cleaned or replaced, water passes through the other water passage, thereby replacing or cleaning the filter screen 7 without stopping the water flow.
[0033] The secondary pipeline 2 runs through the main pipeline 1 horizontally, and the secondary pipeline 2 and the main pipeline 1 are in a cross shape; Figure 5 In the state shown, the second through hole 14 on the auxiliary pipe 2 is used to connect the water inlet and the water outlet of the main pipe 1. In this solution, the upper end of the main pipe 1 is the water inlet, and the lower end is the water outlet; the main pipe 1 is mainly used to connect the drainage pipeline for water flow, and the auxiliary pipe 2 provides an installation position for the filter 7 and the drum mechanism.
[0034] The drum mechanism includes a drum 12, which is rotatably disposed in the auxiliary pipeline 2, and a partition 9 is fixedly disposed inside the drum 12. A first through hole 13 and a filter hole 10 are opened on the drum 12, and the first through hole 13 and the filter hole 10 are separated by the partition 9 so that the drum 12 has two water passages; the drum 12 is rotatably disposed in the auxiliary pipeline 2, and the first through hole 13 and the filter hole 10 thereon can be connected to the second through hole 14;
[0035] The two water passages are specifically: the flow path of one of the water passages is that water enters from the water inlet of the main pipe 1, then flows into the drum 12 from the first through hole 13, and flows to the water outlet of the main pipe 1 after passing through the filter screen 7. This state can be referred to Figure 3 As shown; the flow path of the other water passage is that water enters from the water inlet of the main pipe 1, then flows into the drum 12 from the filter hole 10, and then flows to the water outlet of the main pipe 1. This state can be referred to Figure 8 That is, the switching of the two water paths only requires twisting the drum 12, that is, when the central axis of the first through hole 13 is vertical, water enters the drum 12 from the first through hole 13, and when the central axis of the filter hole 10 is vertical, water enters the drum 12 from the filter hole 10.
[0036] The projection of the central axis of the first through hole 13 and the central axis of the filter hole 10 is in a vertical state. The specific position states of the two can be referred to Figure 6 This arrangement can change the center axis of the first through hole 13 to be vertical or horizontal when the drum 12 is rotated 90 degrees, and the center axis of the corresponding filter hole 10 to be horizontal or vertical.
[0037] A knob 11 is fixedly provided on one end of the drum 12 close to the filter hole 10. The knob 11 is located outside the drum 12, and the knob 11 and the drum 12 are connected by a rotating shaft; the rotating shaft passes through the end of the drum 12 and is rotatably connected to the drum 12, one end of the rotating shaft is fixedly connected to the end face of the drum 12, and the other end is fixedly connected to the knob 11. In order to prevent the knob 11 from malfunctioning, a knob end cover 4 can be used for protection, and the knob end cover 4 is detachably connected to the end of the auxiliary pipe 2 by bolts.
[0038] The filter screen 7 is inserted into the drum 12 and sealed by the filter screen end cover 3. The filter screen end cover 3 is detachably connected to the end of the auxiliary pipe 2, and the filter screen end cover 3 is detachably connected to the end of the auxiliary pipe 2 by bolts. When installing the filter screen 7, the filter screen 7 is directly inserted into the drum 12, and then the filter screen end cover 3 is connected to the auxiliary pipe 2 by bolts, and the filter screen end cover 3 is used to seal the filter screen 7 to prevent water from flowing out or the filter screen 7 from detaching from the drum 12.
[0039] A clamping block 6 is fixedly provided at the outer end of the filter screen 7, and a clamping groove 5 is opened at the end of the auxiliary pipe 2 close to the filter screen 7, and the clamping block 6 and the clamping groove 5 match each other; the clamping block 6 and the clamping groove 5 can be used to limit the filter screen 7 to prevent the filter screen 7 from rotating with the rotation of the drum 12; during installation, when inserting the filter screen 7 into the drum 12, it is necessary to pay attention to the clamping block 6 to be inserted into the clamping groove 5. Only in this way can the filter screen 7 be limited. Otherwise, the filter screen 7 may rotate with the rotation of the drum 12, causing the direction of the filter screen inlet 8 of the filter screen 7 to change. If the direction of the filter screen inlet 8 is turned to the direction of the water outlet of the main pipe 1, it will cause solid dirt to re-enter the drainage pipe.
[0040] Workflow: Under normal use, refer to Figure 3 , the central axis of the first through hole 13 on the rotating drum 12 is in a vertical state, at this time, the filter inlet 8 of the filter screen 7 coincides with the first through hole 13 at the top, and the sewage in the upstream drainage pipe enters from the water inlet of the main pipeline 1, and enters the rotating drum 12 and the filter screen 7 from the first through hole 13 at the top and the filter inlet 8, and then flows out from the first through hole 13 at the bottom, and finally is discharged into the downstream drainage pipe from the water outlet of the main pipeline 1. In this process, the filter screen 7 can filter and collect solid dirt in the sewage, reduce the solid dirt in the drainage pipe, and reduce the risk of pipe blockage; when replacing or cleaning the filter screen 7, refer to Figure 8 , remove the knob end cover 4, and then turn the knob 11 to make the knob 11 drive the shaft and the drum 12 to rotate, so that the central axis of the first through hole 13 is in a horizontal state, and the central axis of the filter hole 10 is in a vertical state. At this time, after the sewage enters the main pipeline 1, it will enter the drum 12 through the upper filter hole 10 and then flow out from the lower filter hole 10. The solid dirt and debris in the sewage will be blocked outside the drum 12 under the action of the filter hole 10, acting as a temporary filtering structure. Since a partition 9 is provided in the drum 12, it is equivalent to completely separating the sewage from the filter screen 7. At this time, the filter screen end cover 3 can be directly removed, and then the filter screen 7 can be taken out for replacement or cleaning, and then the cleaned or replaced filter screen 7 can be reinserted and blocked with the filter screen end cover 3, and then the drum 12 can be rotated to its original state, and the water flow path can be switched, so that the solid dirt and debris just remaining outside the drum 12 enter the filter screen 7, and normal filtering operation is performed, completing the replacement or cleaning of the filter screen 7 without stopping the water flow.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
