Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1, the embodiment of the utility model provides an indoor water supply and drainage device for a large hydropower station technology, which comprises a water outlet tank 1, a water outlet pipe 2, a water filtering barrel 3, a gravity block 4, a rotating shaft 5 and a metal alarm block 6, wherein the water outlet tank 1 and the water outlet pipe 2 are vertically arranged, the water outlet pipe 2 is fixedly arranged in the water outlet tank 1, water outlets 7 are symmetrically arranged at the upper end of the water outlet pipe 2, a filtering hole 8 is arranged at the bottom of the water filtering barrel 3, the water filtering barrel 3 is arranged at the top end of the water outlet pipe 2, a rope 9 is fixedly connected with the top end of the water filtering barrel 3, the tail end of the rope 9 is fixedly connected with the gravity block 4, the rotating shaft 5 is horizontally rotatably arranged on the water outlet pipe 2, water wheels 10 and alarm wheels 11 are fixedly arranged at two ends of the rotating shaft 5, and the metal alarm block 6 is hung above the alarm wheels 11 and is in contact with the alarm wheels 11.

The working principle is as follows: the gravity of the gravity block 4 is larger than the impact force of the water filtering barrel 3 and normal drainage on the water filtering barrel 3, when the water filtering barrel 3 is normally drained, the water filtering barrel 3 is hung on the top of the water outlet pipe 2 under the action of the gravity block 4, the water outlet 7 of the water outlet pipe 2 is blocked by the side wall of the water filtering barrel 3, and water drained from the upper part of the water outlet pipe 2 flows downwards in the water outlet pipe 2 through the water filtering barrel 3; when the water inflow of the drainage ditch is increased, the impact force of inflow water to the water filtering barrel 3 is increased, the water filtering barrel 3 descends, the water outlet 7 of the water outlet pipe 2 is exposed, redundant accumulated water is drained from the water outlet hole, the water discharged from the water outlet hole impacts the water wheel 10 on the rotating shaft 5, the rotating shaft 5 is driven to rotate, the alarming wheel 11 is driven to strike the metal alarming block 6, an alarm is sent out, the staff is reminded of checking abnormal conditions, when foreign matters in the drainage ditch enter the water filtering barrel 3, the water filtering barrel 3 is unsmooth in drainage, the weight of the water filtering barrel 3 is increased, the water outlet 7 of the water outlet pipe 2 is exposed, redundant accumulated water is drained from the water outlet hole, the water discharged from the water outlet hole impacts the water wheel 10 on the rotating shaft 5, the rotating shaft 5 is driven to rotate, the alarming wheel 11 is driven to strike the metal alarming block 6, and an alarm is sent out, so that the staff is reminded of checking abnormal conditions, and the foreign matters in the water filtering barrel 3 are cleared.

In order to avoid that the accumulated water in the water outlet tank 1 covers the metal alarm block 6 and is not easy to give an alarm, as shown in fig. 1, two symmetrical grooved pipes 12 are also fixedly arranged in the water outlet tank 1, the rotating shaft 5 is rotationally connected with the grooved pipes 12, and the alarm wheel 11 is positioned in the grooved pipes 12. The alarming wheel 11 and the metal alarming block 6 are separated from the water of the water outlet tank 1 by the grooved pipe 12, so that the alarming effect is better.

In order to facilitate the metal alarm block 6 to make a louder sound, as shown in fig. 1, a supporting rod 13 is fixedly connected in the grooved tube 12, and the metal alarm block 6 is hinged at the end of the supporting rod 13. The rotating alarm wheel 11 continuously impacts the metal alarm block 6 to make a sound to indicate an alarm, and the metal alarm block 6 is preferably a copper block.

In order to limit the gravity block 4, as shown in fig. 1, the gravity block 4 is disposed in the grooved tube 12, the support rod 13 is provided with a through hole 14, and the rope 9 is inserted into the through hole 14. Preventing the filter tub 3 from being lowered too low.
