DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail in connection with the embodiment below:

[0023] Embodiment 1

[0024] As Figures 1-5 The utility model discloses a drainage structure, including dam 1, the surface of dam 1 is provided with retractable mechanism 3, the surface of retractable mechanism 3 is provided with drainage mechanism 2, and drainage mechanism 2 includes horizontal drainage pipe 201, is fixedly installed on the surface of dam 1, and one end of horizontal drainage pipe 201 extends to the outside of dam 1, and the surface of horizontal drainage pipe 201 is fixedly installed with flexible hose 202, and the inside of flexible hose 202 is provided with spring 205, and one end of flexible hose 202 is fixedly installed with movable drainage pipe 203, and the surface of movable drainage pipe 203 is fixedly installed with fixed seat 206, and fixed seat 206 is fixedly installed on the surface of retractable mechanism 3, and the top end of movable drainage pipe 203 is fixedly installed with escape-proof net 204, and retractable mechanism 3 includes motor 301, and motor 301 is fixedly installed on the surface of dam 1, and the output of motor 301 is fixedly installed with capstan 303, and the surface of capstan 303 is movably installed with support frame 302, and support frame 302 is provided with two groups, and support frame 302 is symmetrically distributed on the surface of capstan 303, and support frame 302 is fixedly installed on the surface of dam 1, and the surface of capstan 303 is provided with rope 305, and the surface of rope 305 is movably installed with fixed pulley 304, and fixed pulley 304 is provided with two groups, and fixed pulley 304 is symmetrically distributed on the two sides of capstan 303 and is fixedly installed on the surface of dam 1, and one end of rope 305 is fixedly installed on the surface of fixed seat 206.

[0025] In this embodiment, the horizontal drain pipe 201 and the movable drain pipe 203 are connected by a flexible hose 202. When it is necessary to discharge water from inside the dam 1, the motor 301 drives the winch 303 on the surface of the support frame 302 to rotate, causing the rope 305 to slide on the surface of the fixed pulley 304. At this time, the spring 205 drives the flexible hose 202 to gradually rebound to a horizontal state, causing the movable drain pipe 203 on the surface of the flexible hose 202 to gradually tilt. The spring 205 is located inside the inner wall, so it will not come into contact with the water flow and cause rust, and it will also avoid entanglement of debris and blockage. At the same time, it provides support for the flexible hose 202, preventing the flexible hose 202 from deforming due to water pressure, thus preventing escape. When the net 204 comes into contact with the water flow, a counterweight is placed on the outside of the fixed base 206. Under the action of gravity, the escape-proof net 204 sinks into the water and will not float. At this time, the water flows through the escape-proof net 204 into the movable drain pipe 203, and then through the flexible hose 202 to be discharged from the pond through the horizontal drain pipe 201, causing the water level in the dam 1 to drop. The escape-proof net 204 can prevent the aquatic animals in the pond from escaping. When drainage is not needed, the motor 301 drives the winch 303 to wind up the rope 305, causing the movable drain pipe 203 to gradually rise until it is perpendicular to the horizontal drain pipe 201. At this time, the escape-proof net 204 is higher than the water level, and drainage can be stopped, which improves the adaptability of the device.

[0026] The working principle of this drainage structure will be explained in detail below.

[0027] like Figures 1-5 As shown, the horizontal drain pipe 201 and the movable drain pipe 203 are connected by a flexible hose 202. When it is necessary to discharge water from inside the dam 1, the motor 301 drives the winch 303 on the surface of the support frame 302 to rotate, causing the rope 305 to slide on the surface of the fixed pulley 304. At this time, the spring 205 drives the flexible hose 202 to gradually rebound to a horizontal state, causing the movable drain pipe 203 on the surface of the flexible hose 202 to gradually tilt. The spring 205 is located inside the inner wall, so it will not come into contact with the water flow and cause rust, and it will also avoid entanglement of debris and blockage. At the same time, it provides support for the flexible hose 202 and prevents the flexible hose 202 from deforming due to water pressure. At this time, the escape net 2... When the device comes into contact with the water flow, a counterweight is placed on the outside of the fixed base 206. Under the action of gravity, the escape-proof net 204 sinks into the water and will not float. At this time, the water flows through the escape-proof net 204 into the movable drain pipe 203, and then through the flexible hose 202 to be discharged from the pond through the horizontal drain pipe 201, causing the water level in the dam 1 to drop. The escape-proof net 204 can prevent the aquatic animals in the pond from escaping. When drainage is not required, the motor 301 drives the winch 303 to wind up the rope 305, causing the movable drain pipe 203 to gradually rise until it is perpendicular to the horizontal drain pipe 201. At this time, the escape-proof net 204 is higher than the water level, and drainage can be stopped, which improves the adaptability of the device.

[0028] The utility model has made the detailed description to the utility model generally, but can make some modification or improvement to it on the basis of the utility model, this is obvious to the general skilled person in the technical field. Therefore, the modification or improvement without departing from the utility model thought spirit, all are within the protection scope of the utility model.
