AI Technical Summary

Problems solved by technology

For example, the strong dependence on manual operation is mainly reflected in the fact that some waterproof doors or waterproof panels are purely mechanical structures, and when a dangerous situation occurs, manual operations are required to close or manual on-site splicing is required
If the danger occurs at night and no one is on duty, the danger cannot be stopped in time
In addition, the problems of insufficient water pressure resistance and poor sealing performance are mainly due to different application fields, which require different design requirements.
For example, it is not easy to use plastic flexible folding waterproof doors to meet such flood protection requirements

Embodiment 1

[0070] Embodiment 1: In combination with all the accompanying drawings; the fully automatic waterproof door suitable for the entrance and exit of underground facilities is characterized in that it includes a door installed at the garage door, the door is a single door or a double door,

[0071] The right-angle steel of the column is fixed on the wall at the entrance and exit of the underground garage through expansion bolts 34 as a right-angle area; the column contains a central column 31, and the door leaf is installed on the column through a bearing 30, and the door leaf can rotate around the central column 31 to complete the opening of the waterproof door and close action;

[0072] The two sides of the door leaf body, that is, the two surfaces of the door leaf perpendicular to the ground, contain air pressure sealing strips 24. The air pressure sealing strips 24 are connected to the air circuit 33, and the air circuit 33 is connected with a switching solenoid valve and a pre...

Embodiment 2

[0084] Embodiment 2: As a further improved solution or a side-by-side solution or an optional independent solution, double-layer brushes 36 are provided on both sides of the airbag slot 35, and a stainless steel embedded steel plate 6 is provided on the ground in contact with the sealed airbag; When the waterproof door is opened and closed, the brush 36 can remove foreign matter on the ground; the pre-embedded steel plate 6 with a smooth surface can be closely attached to the sealed air bag as the contact ground. The substantive technical effect and its realization process played by the technical solution here are as follows: the effect of the air bag draw-in groove 35 is under the effect of air pressure, the air bag draw-in groove 35 can limit the sealing form of the sealed air bag 23, and ensure that it is in contact with the ground The limited contact area of ​​the buried steel plate 6 ensures its tightness; the function of the brush 36 is to adopt the alternate design of do...

Embodiment 3

[0085] Embodiment 3: As a further improved solution or a side-by-side solution or an optional independent solution, it also includes a prefabricated seal 32. The prefabricated seal 32 fits on the right-angled area of ​​the column and the semicircular surface of the door leaf to ensure that the water outside the waterproof door Can not infiltrate through the gap; The liquid level gauge 2 37 is arranged on the outer wall of the door leaf. The substantive technical effect and its realization process played by the technical solution here are as follows: the prefabricated seal 32 fits on the right-angled area of ​​the left column and the semicircular surface of the left door, and its effect is: in the air passage 33, there is In the case of air pressure and two air pressure sealing strips 24 all fail, it can also ensure that the water outside the waterproof door will not infiltrate through the gap, and the form of multiple measures will ensure the airtightness of the waterproof door...

Abstract

The invention relates to the field of building infrastructures, in particular to a full-automatic waterproof door and method suitable for underground facility entrances and exits. The right-angle steel of the stand column serves as a right-angle area and is fixed to the wall of the entrance and exit of the underground garage through expansion bolts (34); the door leaf is installed on the stand column through a bearing (30) and can rotate around a center column (31), and opening and closing actions of the waterproof door are completed; the stand column comprises an air pressure sealing strip (24), the interior of the air pressure sealing strip (24) is communicated with an air channel (33), the air channel (33) is connected with a switching electromagnetic valve and a pressure accumulator (27), and the pressure accumulator (27) is connected with a pneumatic pump (11); a sealing air bag (23) at the bottom of the waterproof door ensures the sealing performance; and the sealing air bag (23) is arranged in the air bag clamping groove (35). Compared with a common waterproof door, the waterproof door is high in automation degree, a specially-assigned person does not need to be arranged for guarding, it can be ensured that the waterproof door can be closed in time when a dangerous case occurs, and the protection effect is achieved.

Description

technical field [0001] The invention relates to the field of building infrastructure, in particular to a fully automatic waterproof door and method suitable for entrances and exits of underground facilities. Background technique [0002] With the change of climate, natural disasters have been intensified in recent years. Taking the continuous torrential rain in Zhengzhou in 2021 as an example, because the entrances and exits of underground garages in most residential areas and shopping malls have not installed waterproof doors, hundreds of thousands of vehicles of vehicles were submerged, causing significant economic losses. What's more serious is that the torrential rain poured into the underground subway station and the city's underpass tunnel, which not only caused the flooding of vehicles and facilities, but more unfortunately caused the death of people. Although there are different designs and products of waterproof doors or waterproof boards on the market, there is a ...
