In an embodiment of the above technical solution, a plane size of the water baffle is larger than a size of the ventilation opening.
In one embodiment of the above technical scheme, the water stop strip is a water-swelling rubber water stop strip, the periphery of the back surface of the water baffle is attached in a loop, and the adjacent edges are overlapped.
In one embodiment of the above technical solution, the plane size of the water baffle is 80-120mm larger than the size of the vent, the outer sides of the water stop strips and the water baffle are 50-60mm, and the overlapping length between the adjacent water stop strips is at least 100 mm.
In one embodiment of the above technical solution, the vent sidewall connecting member is a rectangular steel plate having a mounting hole thereon.
In one embodiment of the above technical scheme, the water baffle fixing member comprises an angle steel and a fastening bolt, a thick nut is welded at the middle position of one side arm of the angle steel, a round hole is formed in the position, corresponding to the thick nut, of the angle steel, and the fastening bolt is connected in the thick nut and the round hole; the side wall connecting member of the vent is vertically welded to the middle part of the side edge of the other side arm of the angle steel.
This subassembly is at the attached sealing rod in the back of breakwater, and the breakwater is fixed through multiunit installation component, and the installation component passes through expansion bolts to be fixed in the vent lateral wall, and the breakwater can be dismantled through the installation component and compress tightly in vent department. Particularly, the square steel plate of the mounting assembly is fixed on the side wall of the vent through an expansion bolt, the water baffle covers the vent after being attached to the water stop strip, and then the square steel plate is tightly pressed through a fastening bolt connected to angle steel. When the water level reaches the vent in the flood season, the water stop strip on the back of the water baffle expands when encountering water to play a sealing role and blocks flood together with the water baffle. And after the flood season, taking down the fastening bolt and then taking down the water baffle for storage. The water baffle and the fastening bolt can be reused in the later flood season, and the water stop band needs to be replaced. This subassembly can use repeatedly after the installation for the first time promptly, and secondary installation is convenient and fast moreover.

Detailed Description
As can be seen from fig. 1 to 4, the flood control assembly for temporarily closing the ventilation opening of the air supply/exhaust well of the underground pipe gallery in the flood season disclosed in the present embodiment includes a water baffle 1, a water stop 2 and a mounting assembly 3.
The plane size of the water baffle 1 is larger than the size of the ventilation opening, and the periphery of the water baffle preferably exceeds the size of the four sides of the ventilation opening by 100 mm.
The water baffles at the air vents are manufactured according to actual requirements.
The water baffle can be made of wood plates or metal plates, and when the wood plates are adopted, the thickness of the water baffle is preferably 14-18 mm. When the metal plate is adopted, the aluminum alloy plate with the thickness of 2mm is preferably selected, so that the water baffle is light in weight and convenient to process and install.
The water stop strip 2 is made of water-swelling rubber water stop strip with back glue, and the thickness of the water stop strip is at least 6 mm.
The water stop strips 2 are attached to the back of the water baffle 1, when the water stop strips are attached, the distance between the outer sides of the water stop strips and the edge of the water baffle is preferably 50mm, the water stop strips are mutually lapped to form a ring, and the lapping length is not less than 100 mm.
The mounting assembly 3 includes angle steel 31, square steel plate 32, thick nut 33 and fastening bolt 34.
The square steel plate 32 is used as a vent side wall connecting member, and a round hole is formed in the center of the square steel plate and fixed to the vent side wall through an expansion bolt.
The angle steel 21, the thick nut 33 and the fastening bolt 34 are used as a water baffle fixing component, a round hole is formed in the middle of one side arm of the angle steel, the thick nut 33 is welded on the outer side of the round hole, and the fastening bolt 34 is connected in the thick nut 33 and the round hole.
The square steel plate 32 is vertically welded to the middle part of the side edge of the other side arm of the angle steel 21.
The installation process of this flood control subassembly is as follows:
and selecting a water baffle with proper size according to the size of the ventilation opening, determining that the length direction and the width direction respectively adopt a plurality of groups of mounting assemblies according to the condition that the distance between adjacent mounting assemblies is not more than 500 mm.
And determining the installation position of the expansion bolt according to the selected height of the water baffle, positioning and punching the side wall of the ventilation opening and installing the expansion bolt.
And mounting assemblies are respectively mounted at the expansion bolts, and fastening bolts of the mounting assemblies are screwed into the thick nuts.
And installing the water baffle attached with the water stop strip, screwing each fastening bolt to tightly press the water baffle, and plugging the ventilation opening. When the water level reaches the vent in the flood season, the water stop strip on the back of the water baffle expands when encountering water to play a sealing role, and blocks flood together with the water baffle, so that the plugging effect is reliable.
And after the flood season, taking down the fastening bolt of the mounting assembly, then taking down the water baffle plate, and reserving the angle steel and the square steel plate integral piece of the mounting assembly at the vent.
The water baffle and the fastening bolt which are taken down are stored and can be repeatedly installed and used when needed later. This subassembly can use repeatedly through the installation for the first time promptly, and secondary installation is very convenient moreover.
