Problems solved by technology

However, due to its light weight and high material performance requirements; and there are many sediments in the flood, the buoyancy of the water retaining board is too small, and it is easily affected by the mud and sand in the flood, so the water retaining board cannot float
[0005] The electrically activated active flood protection device needs manual control, and in order to avoid short circuit, the electric device needs to be set at a higher position; the transmission distance is longer; and it cannot be used in case of power failure
[0006] Manually installed flood protection devices are too time-consuming and may not be installed in an emergency

Embodiment 1

[0038] Such as Figure 1 to Figure 5 As shown, this embodiment discloses a flood prevention device for the entrance of an underground building, which includes a storage tank-1 located at the entrance of the underground building; The bottom of the holding tank 1 is supported by a cylinder 3, and the air inlet of the cylinder 3 communicates with the gas generator 5; the gas generator 5 utilizes the chemical reaction between water and chemical substances in the flood to generate gas, and the The chemical substance is calcium carbide 53, and the calcium carbide 53 is calcium carbide; and the air pressure generated by the release of the gas drives the preset structure to perform a movement to form a waterproof structure; the preset structure includes the accommodation tank 1, the water retaining plate 2 and the cylinder 3, the waterproof structure is the integral structure when the cylinder 3 is extended in the preset structure. When the gas generator 5 is submerged in water, the ...

Embodiment 2

[0044] Such as Figure 3 to Figure 7 As shown, this embodiment discloses a flood prevention device for the entrance of an underground building, which includes a storage tank-1 located at the entrance of the underground building; The bottom of the holding tank-1 is supported by an airbag 4, and the air inlet of the airbag 4 is connected to the gas generator 5; the gas generator 5 utilizes the chemical reaction between water and chemical substances in the flood to generate gas, and the The chemical substance is calcium carbide 53, and the calcium carbide 53 is calcium carbide; and the air pressure generated by the release of the gas drives the preset structure to perform a movement to form a waterproof structure; the preset structure includes the accommodation tank 1, the water retaining plate 2 and the airbag 4, the waterproof structure is the integral structure when the airbag 4 is inflated in the preset structure. When the gas generator 5 is submerged in water, the generated...

Embodiment 3

[0050] This embodiment discloses a vehicle flood control method, the method is to use the water in the flood to react with chemical substances to generate gas; and the air pressure generated by the release of the gas drives the preset structure to perform a movement to form a waterproof structure, or the The release of the gas activates the preset structure to form a waterproof structure. The chemical substance is calcium carbide, and the calcium carbide is calcium carbide. When the flood water comes into contact with calcium carbide, a violent reaction occurs and acetylene is released; the generation of acetylene initiates or drives the preset structure to form a waterproof structure. Human control is not required, and the power obtained by simply using the buoyancy of water is more sufficient.

Abstract

The invention discloses an underground building entrance flood control method and device and a vehicle flood control method. According to the method and the device, water in the flood and chemical substances are subjected to chemical reaction to generate gas; and a preset structure is driven by the air pressure generated by the release of the air to move to form a waterproof structure, or the preset structure is started by the release of the air to form the waterproof structure, the chemical substance is calcium carbide, the calcium carbide is calcium carbide, after the flood is in contact with the calcium carbide, violent reaction occurs, acetylene is released, acetylene generation starts or drives the preset structure to form the waterproof structure, manual control is not needed, and power obtained by the device is more sufficient than power obtained by purely utilizing buoyancy of water.

Description

technical field [0001] The invention relates to the technical field of flood control for underground buildings, in particular to a flood control device for an entrance of an underground building and a method for preventing floods at the entrance of an underground building. [0002] The invention also relates to the technical field of vehicle flood protection, in particular to a method for vehicle flood protection. Background technique [0003] When underground buildings such as subways and underground garages suffer from floods, they are prone to be flooded backwards, endangering life, property and health. Present underground building flood prevention device is generally divided into two parts. The first part is to install a flood retaining device at the entrance of the underground building; the second part is to install a pumping device or a water storage device at the lowest point of the underground building. For flood-retaining devices, such as subways, steps of 30-60cm...
