For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example: Refer to Figure 1-7 , a building water supply and drainage system energy-saving control method, comprising the following steps: S1: water flows into the drainage pipe 11 from the water inlet, and flows along the inner wall of the drainage pipe 11 to the bent pipe 1; S2: The flow potential energy of the water flow in the drainage pipe 11 drives the toggle assembly 3 at the bent pipe 1 to automatically work, so that the toggle assembly 3 moves the debris deposited at the corner of the bent pipe 1, so that the debris can continue to flow toward the water outlet of the drainage pipe 11 along the water flow; S3: After the water flows through the inside of the bent pipe 1 , the impact component 4 impacts the debris remaining at the corner of the bent pipe 1 , so that the debris will not be retained in the bent pipe 1 .

[0024] Reference Figure 1-7As a preferred technical solution of the present invention, further, the bent pipe 1 is arranged on the drainage pipe 11, an arc-shaped shell 2 is fixedly provided on the outside of the bent pipe 1, the arc-shaped shell 2 and the bent pipe 1 are communicated with each other, a toggle assembly 3 for removing debris at the corner of the bent pipe 1 is arranged between the bent pipe 1 and the arc-shaped shell 2, an impact assembly 4 is connected to the toggle assembly 3, and a gear transmission mechanism is arranged between the toggle assembly 3 and the impact assembly 4.

[0025] Specifically, by utilizing the water flow in the drainage pipe 11, the potential energy carried by the water flow automatically drives the toggle component 3 at the bent pipe 1 to work, thereby avoiding the working energy consumption caused by the drive of the electric equipment. At the same time, the toggle component 3 prevents debris from being easily deposited at the bottom of the corner of the drainage pipe 11, making the corner of the drainage pipe 11 not easily blocked, thereby ensuring the normal operation of the drainage system. When the toggle component 3 is working, the gear transmission mechanism is used to drive the impact component 4 to move, so that the impact extracts part of the water flowing in the bent pipe 1. When there is no water flowing in the drainage pipe 11, the impact component 4 is reset and the extracted water is discharged, so that the discharged water impacts the bend of the bent pipe 1, further preventing debris from being deposited at the bottom of the corner of the drainage pipe 11, thereby ensuring the normal operation of the drainage system.

[0026] Reference Figure 1 , Figure 2 and Figure 4 As a preferred technical solution of the present invention, further, the toggle assembly 3 includes a rotating rod 301 rotatably connected to the arc-shaped housing 2 and a toggle plate 302 uniformly arranged on the outside of the rotating rod 301 in a circumferential manner, and the toggle plate 302 is movably abutted against the inner wall of the bent pipe 1.

[0027] Specifically, the flow potential energy of the water flow in the drainage pipe 11 drives the toggle plate 302 to rotate, and the toggle plate 302 drives the rotating rod 301 to rotate. When the toggle plate 302 rotates, it toggles the debris deposited at the corner of the bent pipe 1, so that the debris can continue to flow along the water flow to the outlet of the drainage pipe 11, making it difficult for the debris to settle at the bottom of the corner of the drainage pipe 11, and making the corner of the drainage pipe 11 difficult to be blocked, thereby ensuring the normal operation of the drainage system.

[0028] Reference Figure 1 , Figure 2 and Figure 4 As a preferred technical solution of the present invention, further, the toggle plate 302 includes a main board body 3021 fixedly connected to the rotating rod 301, and a plurality of recessed holes 3022 are provided on the main board body 3021. The inner wall of each recessed hole 3022 is rotatably connected to a movable plate 3023 through a pin shaft, and the movable plate 3023 and the inner wall of the recessed hole 3022 are movably abutted against each other, and the inner walls of the recessed hole 3022 and the movable plate 3023 are provided with matching extrusion slopes.

[0029] Specifically, by providing a rotatable movable plate 3023 on the main body 3021 of the toggle plate 302, when the toggle plate 302 passes over the corner of the bent pipe 1, the toggle plate 302 automatically droops, causing the concave hole 3022 of the main body 3021 to leak out. On the one hand, the resistance to the upward rotation of the toggle plate 302 is reduced, and on the other hand, the toggle plate 302 is prevented from toggling the water flowing in the bent pipe 1 into the arc-shaped outer shell 2, causing the water to re-enter the bent pipe 1 and flow, affecting the discharge rate of the water from the drainage pipe 11, thereby ensuring the smooth and orderly operation of the toggle component 3.

[0030] Reference Figure 1-7 As a preferred technical solution of the present invention, further, the impact assembly 4 includes a working tube 401 fixedly arranged on the outside of the bent pipe 1, a piston 402 slidably connected in the working tube 401, and an elastic element 403 arranged between the piston 402 and the inner wall of the working tube 401, the piston 402 is connected to the gear transmission mechanism, and the working tube 401 is provided with a liquid inlet valve and a liquid outlet valve, the working tube 401 is connected to a liquid inlet pipe 404 through the liquid inlet valve, and the end of the liquid inlet pipe 404 away from the working tube 401 is connected to the bent pipe 1, the working tube 401 is connected to a liquid discharge pipe 405 through the liquid outlet valve, and the end of the liquid discharge pipe 405 away from the working tube 401 passes through the bent pipe 1 and extends into the rotating rod 301.

[0031] Furthermore, the gear transmission mechanism includes a main gear 5 arranged on the outside of the rotating rod 301 and a sub-gear 6 meshing with the main gear 5. The main gear 5 and the sub-gear 6 are both rotatably connected to the arc-shaped outer shell 2. A rotating shaft 601 is provided on the sub-gear 6. A reel 602 is provided on the rotating shaft 601. A pull rope 603 is wound around the reel 602. One end of the pull rope 603 away from the reel 602 passes through the working tube 401 and is connected to the piston 402. A protective shell 7 for covering the gear transmission mechanism is fixed on the arc-shaped outer shell 2.

[0032] Furthermore, a coil spring 10 for driving the rotating shaft 601 to rotate is disposed on the arc-shaped housing 2 . The coil spring 10 is sleeved on the outer side of the rotating shaft 601 , and the auxiliary gear 6 is configured as a one-way gear.

[0033] Furthermore, the drain pipe 405 is placed inside the bent pipe 1 and is coaxially arranged with the rotating rod 301. The rotating rod 301 is sleeved on the outside of the drain pipe 405. The rotating rod 301 is provided with a groove 3011. The drain pipe 405 is placed inside the rotating rod 301 and has a plurality of drain ports 4051.

[0034] Specifically, when the rotating rod 301 rotates, the main gear 5 and the sub-gear 6 are meshed and transmitted, and when the sub-gear 6 rotates, the rotating shaft 601 and the reel 602 on the rotating shaft 601 are driven to rotate, and the reel 602 reels the pull rope 603, and the pull rope 603 applies a pulling force to the piston 402 in the working tube 401, and the working tube 401 extracts the water flowing in the bent pipe 1 through the liquid inlet pipe 404. When there is no water flowing in the drainage pipe 11, the toggle assembly 3 stops working, and the rotating shaft 601 is reset and rotated under the action of the coil spring 10, and the rotating shaft 601 drives the sub-gear 6 and the reel 602 to rotate. Since the sub-gear 6 is set as a one-way gear, the resetting rotating sub-gear 6 will not drive the main gear 5 to rotate. When the reel 602 resets and rotates, the pull rope 603 is released, and the piston 402 is reset under the elastic force of the elastic element 403. The working pipe 401 discharges the extracted water through the discharge port 4051 through the discharge pipe 405. The discharged water impacts the bend of the bent pipe 1, further preventing debris from being deposited at the bottom of the corner of the drainage pipe 11, thereby ensuring the normal operation of the drainage system.

[0035] Reference Figure 3 As a preferred technical solution of the present invention, further, a through hole connected to the liquid inlet pipe 404 is opened on the bent pipe 1, and a filter screen 8 is arranged at the through hole; specifically, by arranging the filter screen 8 at the connection between the liquid inlet pipe 404 and the bent pipe 1, it is prevented that when the working pipe 401 extracts the water flowing in the bent pipe 1 through the liquid inlet pipe 404, impurities in the water enter the liquid inlet pipe 404, causing the liquid inlet pipe 404 to be blocked, thereby affecting the normal operation of the impact assembly 4.

[0036] Reference Figure 2 As a preferred technical solution of the present invention, further, a guide plate 9 is fixedly provided in the bent pipe 1, and the guide plate 9 is placed on the inner wall of the bent pipe 1 on one side close to the arc-shaped shell 2; specifically, by arranging the guide plate 9 in the bent pipe 1, the flow direction of the water body in the bent pipe 1 can be guided, so that the water body impacts the toggle plate 302 of the toggle component 3, ensuring that the toggle component 3 works under the impact of the water flow.
