Problems solved by technology

However, these facilities are very inconvenient to arrange in the rain. If they are arranged in advance, they will hinder the normal use of the roads. Moreover, after the heavy rain, they need to be removed manually, which is time-consuming and laborious.

Embodiment 1

[0020] Embodiment 1: as figure 1 The louvered flood wall shown includes a fixed column 1 fixed on the ground, and the fixed column 1 can be fixed against the left wall or hidden inside the left wall. Such as Figure 4 As shown, the right wall 6 is provided with a wall water-tight sealing layer structure.

[0021] An upper beam 2 and a lower beam 3 are respectively hinged on the upper side and the lower side of the fixed column 1 through a rotating shaft, and a plurality of water-retaining sheets 5 are sequentially hinged between the upper beam 2 and the lower beam 3, and each water-retaining sheet 5 passes through The rotating shaft at the center of its upper and lower ends is installed between the upper beam 2 and the lower beam 3 . Edge sealing strips are provided at the ends of the upper beam 2 and the lower beam 3 . A driving mechanism 4 is arranged inside the fixed column 1, and the driving mechanism 4 drives the upper beam 2 or the lower beam 3 to rotate along its rot...

Embodiment 2

[0027] Embodiment 2: On the basis of Embodiment 1, a sheet automatic closing drive mechanism is provided. see Figure 9 and Figure 10 , the sheet automatic closing drive mechanism includes a push-pull rod 18, a series of shaft holes are evenly distributed on the push-pull rod 18, and a push-pull drive shaft 17 is provided at the upper or lower end of each water-retaining leaf 5, each push-pull drive The shaft 17 is installed in each shaft hole of the push-pull rod 18 in turn. The end of the push-pull rod 18 is provided with a stopper, and the stopper is located outside the rotating shaft of the upper crossbeam 2 or the lower crossbeam 3 . The movement of push-pull rod 18 can be driven by hand to realize the closure of each water-retaining leaf, and the end block 19 of the push-pull rod can also be utilized to contact the rotating shaft to realize the automatic closing of each water-retaining leaf.

Abstract

The invention discloses a louver type flood control wall, which comprises a column fixed on the ground, an upper beam and a lower beam are respectively hinged on the upper side and the lower side of the column through a rotating shaft, and a plurality of baffles are sequentially hinged between the upper beam and the lower beam Water sheets, each water retaining sheet is installed between the upper beam and the lower beam through the rotating shaft at the center of the upper and lower ends. The present invention can be in the hidden state in the normal non-flood period without affecting the normal use of the channel. When the flood comes, the flood control wall is dropped by controlling the driving mechanism, and the folding flood control wall is reinforced and fixed by using the auxiliary rod. Thus, the flood control function can be quickly completed. The operation is convenient and fast, and no other flood protection facilities are required. The invention has the advantages of simple structure, fast operation and good use effect, and is very suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of flood control equipment for entrances and exits of underground spaces, and in particular relates to a louvered flood control wall. Background technique [0002] In recent years, frequent rainstorms and abnormal rainfall have sounded the alarm for our country's flood control work. Due to the changes in the precipitation runoff process brought about by urbanization and the lack of urban drainage capacity, urban areas will frequently suffer from waterlogging in the event of heavy rain. . It seriously threatens the safety of people's life and property and the effective operation of urban underground facilities. In the face of this situation, the traditional method of flood control is to use sandbags and wooden boards to block the influx of rainwater. However, the sudden onslaught of heavy rain often has no time to find sandbags and other flood control items. Anti-blocking threatens the safety of people's li...
