Description

Technical Field

[0001] The utility model belongs to the field of water environment management, and in particular relates to a controllable flap door component for a river outlet. Background Art

[0002] At present, most of the existing flap gates use gravity as the power source for closing the flap gate. When the water level potential energy in the pipeline is greater than the gravitational potential energy of the flap gate and the river water level potential energy, the flap gate opens. When the water level in the pipeline is insufficient, the flap gate is pressed down by its own weight and the static pressure of the external water level to prevent the river water from flowing back into the pipeline. However, due to the disrepair of the flap gate or interference from debris in the river channel or pipeline, a gap will appear between the flap gate plate and the flap gate base, resulting in water leakage. The interception well forms a connecting vessel with the external river channel through the interception pipeline, and some sewage will flow into the river channel by itself and cannot be controlled. According to this situation, a controllable flap gate is needed to solve the above problems. Utility Model Content

[0015] The utility model is described in detail below in conjunction with the accompanying drawings.

[0016] Embodiment 1,

[0017] like Figure 1-3 As shown, a controllable flap gate assembly for a river outlet includes a flap gate base 1 and a flap gate plate 2. The base 1 is installed on a pipe, and the upper end of the flap gate plate 2 is hinged on the flap gate base 1. A static ring 5 and a dynamic ring 3 are respectively provided on the opposite surfaces of the flap gate base 1 and the flap gate plate 2. A groove 6 is opened on the static ring 5, and an electromagnetic coil 10 is arranged in the groove 6. A circular iron sheet 9 is provided on the dynamic ring 3, and the iron sheet 9 and the electromagnetic coil 10 are positioned opposite to each other.

[0018] There are multiple groups of iron sheets 9 and electromagnetic coils 10. In this embodiment, there are three groups of iron sheets 9 and electromagnetic coils 10, which are respectively located on the left and right sides and the lower part of the flap door plate 2 and the flap door base 1.

[0019] The electromagnetic coil 10 is wound around the screw 7 , and the screw 7 is installed in the groove 6 through threads.

[0020] A wire slot 8 is provided on the side of the groove 6 , and the electromagnetic coil 10 is connected to a DC power source through a DC power line, and the DC power line is led out from the wire slot 8 .

[0021] A water level sensor is arranged in the pipeline, and both the DC power supply and the water level sensor are connected to the control system.

[0022] A circular rubber gasket is provided on one side of the flap door base 1 facing the flap door panel 2 to increase airtightness.

[0023] The flap gate base 1 is embedded in advance when pouring concrete, and the steel bars on the flap gate base 1 are welded to the steel bars of the concrete structure to ensure that the flap gate base 1 is fixed to the embankment.

[0024] Arrange the DC power line in the wire slot 8; fix the electromagnetic coil 10 in the groove 6 with screws 7, and connect the DC power line to the electromagnetic coil 10; seal the groove 6 and the wire slot 8 with silicone to improve the waterproof performance.

[0025] When the water level in the pipeline is low and does not reach the set water level of the water level sensor, the controller turns on the DC power supply, and the electromagnetic coil 10 generates magnetism after being energized, attracting the iron sheet 9 on the flap door panel 2, so that the flap door panel 2 fits tightly with the flap door base 1, and the flap door is reliably closed to ensure that sewage does not overflow. When the water level in the pipeline rises and reaches the set water level of the water level sensor, the controller turns off the DC power supply, the electromagnetic coil is powered off and demagnetized, and the attraction to the flap door panel 2 is released. At this time, the water flow that has obtained kinetic energy reaches the flap door panel 2 and pushes the flap door panel 2 open, draining water to the river channel normally, and rainwater flows into the river.
