Automatic water stop device

Abstract

The invention relates to an automatic water stop device which comprises a face plate (1), a hinged base (3) and a base (5). The hinged base (3) is arranged at one end of the base (5), one end of the face plate (1) is hinged to the hinged base (3), the other end of the face plate (1) can perform arc rotation along the hinged base (3), and a water inlet-outlet hole (51) is formed in one end of the base (5). The automatic water stop device further comprises a floating plate (2). The floating plate (2) is arranged on the face, close to the base (5), of the face plate (1). When water enters the base (5) from the water inlet-outlet hole (51) or space above the base (5), the floating plate (2) can drive the face plate (1) to upwards rotate along the hinged base (3) under the effect of floating force of the water. According to the automatic water stop device, external-force driving is not needed, the water is automatically stopped, and the automatic water stop device is simple in structure, low in cost and easy to install.

Description

1. Technical field [0001] The invention relates to a water retaining device, in particular to an automatic water retaining device. 2. Background technology [0002] In recent years, urban waterlogging due to short-term torrential rains has also occurred from time to time, especially in underground garages. Due to the inability to discharge water in time, a large number of vehicles have been flooded, and similarly, huge property losses have also been caused. The reason is that, on the one hand, the torrential rains in recent years have become more and more violent, and the inflow of water in the drainage design is insufficiently estimated; on the other hand, there are also technical difficulties, and it is difficult to take preventive measures, such as Use sandbags to block the water flow and prevent it from flowing into the garage from the garage exit, but the sandbags are difficult to carry.

Problems solved by technology

[0002] In recent years, due to short-term torrential rains, urban waterlogging has also occurred from time to time, especially in underground garages. Because the water cannot be discharged in time, a large number of vehicles have been flooded. Similarly, huge property losses have also been caused.

The reason is that, on the one hand, the torrential rains in recent years have become more and more violent, and the inflow of water in the drainage design is insufficiently estimated; on the other hand, there are also technical difficulties, and it is difficult to take preventive measures, such as Use sandbags to block the water flow and prevent it from flowing into the garage from the garage exit, but the sandbags are difficult to carry

Chinese patent 201320723563.4 proposes a waterproof and submerged system for underground garages, which requires external power and monitoring of the water level to achieve water retention. The system is complex and the reliability is reduced; Floating barrel chambers and water storage tanks corresponding to multiple floating bucket chambers. The upper part of each water storage tank is c
