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 connected to the corresponding floating bucket chamber through a water guide pipe, and a water grate is covered on the top of each water storage tank. A flood control baffle is provided on the top of each floating bucket chamber by rotating the shaft cover, and the reinforced support cover set in the floating bucket chamber is supported and arranged at the lower part of the flood control baffle, and each floating bucket chamber is provided with a floating bucket, the floating bucket The top is rotatably connected with one end of the reinforcement rod through a bearing, and the other end of the reinforcement rod is connected with the flood baffle through the reinforcement cover plate, and a drain pipe is connected to the lower side wall of each buoy chamber

When the structure is sunny or the amount of rain is small, the water retaining board is placed horizontally on the same level as the ordinary road. As the rainfall increases, it will automatically play the role of retaining water, but it is necessary to set up a floating bucket room, a storage tank, etc., and the system Complex, difficult to construct and install
