Automatic-and-manual combined type water retaining device and water retaining method thereof

Abstract

The invention discloses an automatic-and-manual combined type water retaining device and a water retaining method thereof. The water retaining device comprises a base and an automatic water fender rotatably arranged on the base, and is characterized in that the water retaining device further comprises one or more manual water fenders used for being detachably mounted on the upper portion of the automatic water fender, and the bottoms of the manual water fenders used for being connected with the automatic water fender can be attached to the free end of the automatic water fender. The method includes the first step of triggering the automatic water fender for giving out an alarm, the second step of preparing installation of the manual water fenders, the third step of installing the manual water fenders, the fourth step of dismounting the manual water fenders and the fifth step of resetting the manual water fenders. The automatic-and-manual combined type water retaining device and the water retaining method thereof have the beneficial effects that the automatic water fender and the manual water fenders are combined, on the one hand, people have enough time to rush to the water retaining device, and on the other hand, the number of the manual water fenders is determined according to the rainfall, so that the effect that rainwater cannot enter underground buildings is guaranteed to the maximum extent, and the automatic water fender can be effectively detected at ordinary times.

Description

technical field [0001] The invention relates to an automatic and manual combined water blocking device and a method for blocking water. Background technique [0002] With the development of urban building groups, especially the utilization of underground buildings, such as: the widespread use of underground shopping malls, underground garages, and underground warehouses, taking effective waterproofing measures in urban underground and low-lying places is the key to avoiding and reducing property losses. Low-lying buildings The most effective way to prevent floods is to set up flood control water gates at the entrance. [0003] The existing water retaining method is to set up water retaining devices at the entrance and exit of the underground building. There are two existing water retaining devices, one is purely manual, as disclosed in the Chinese invention patent No. 201520568201.1, including The brackets on both sides and the detachable water baffles installed on the brac...

Problems solved by technology

Another water retaining device is an automatic water retaining device. The applicant filed a patent application on February 4, 2016. The water retaining plate uses the buoyancy of water to float to realize the automatic water retaining function. The disadvantage of this water retaining device is The cost per unit area of ​​the water retaining plate is high, and the cost will increase greatly for underground buildings that require a large water retaining height

Moreover, due to the increased height of the water retaining plate, the difficulty of installing the automatic water retaining device on the ground will also increase greatly

In addition, if the rainfall is particularly heavy and the depth of the rainwater exceeds the height of the water retaining plate, the rainwater will still enter the underground building through the top of the water retaining plate, causing damage to the property in the underground building.

In addition, the existing automatic water barrier lacks effective means of daily detection
