[0039] The gate body 1 is matched with the gap of the wave-preventing wall.
[0040] The hinging mechanism is composed of the hinge support plate 21, the hinge seat plate 23 and the pluggable hinge shaft 22 arranged at the side edge of the gate.
[0041] The sealing structure comprises the P-shaped waterstop 31 arranged at the edge of the gate.
[0042] The anchor steel bars 24 are welded at the lower part of the hinge seat plate 23, and the anchor steel bars 24 are welded and connected with the internal steel mesh of the wave-preventing wall.
[0043] The locking mechanism 4 is arranged outside the gate body 1, so as to prevent accidental opening.
[0044] The observation window 5 is composed of the vertically arranged explosion-proof glass 51, and the surface is provided with the water level scale mark 52.
[0045] It should be noted that, as Figures 1 to 3 The floodgate comprises the gate body 1, the hinging mechanism, the sealing structure, the locking mechanism 4 and the observation window 5. The gate body 1 is welded by steel structure, and the shape is matched with the size of the gap of the wave-preventing wall, so as to ensure that the gate body 1 is closely combined with the wall body when closed.
[0046] The hinging mechanism is composed of the hinge support plate 21, the hinge seat plate 23 and the pluggable hinge shaft 22 arranged at the side edge of the gate. The hinge seat plate 23 is welded on the top of the wave-preventing wall through the embedded steel plate, and the bottom surface is welded with the multiple anchor steel bars 24 in the C-shaped distribution mode. The material of the anchor steel bars 24 is HRB400, and the diameter is greater than or equal to 16 mm. The anchor steel bars 24 are welded with the internal steel mesh of the wave-preventing wall to form an integral force structure. The pluggable hinge shaft 22 is made of stainless steel, and is inserted into the reserved hole position of the hinge seat plate 23 during installation, so as to realize the rotating opening and closing function of the gate body 1.

The explosion-proof glass 51 preferably adopts a three-layer laminated structure, the outer layer is tempered glass, and the middle layer is PVB film. The explosion-proof glass 51 is embedded in the clamping groove 531 of the I-beam longitudinal beam 53, and the water stop rubber 54 is arranged on the contact surface between the clamping groove 531 and the glass to prevent water seepage. The surface of the explosion-proof glass 51 is printed with the water level scale mark 52 covering the full height of the gate, which is printed with fluorescent paint visible at night, so as to facilitate real-time monitoring of the water level.
[0056] Further, the bottom surface of the hinge seat plate 23 is arranged in a C shape and welded with anchor steel bars 24. The I-beam longitudinal beam 53 adopts Q2435B steel, and the width of the clamping groove 531 is at least 2mm larger than the thickness of the explosion-proof glass 51. After the water stop rubber 54 is installed, polyurethane sealant is filled to enhance the waterproof performance.
[0057] Among them, the locking mechanism 4 adopts the same principle as the existing truck rear compartment hand buckle hook.
