The drainage structure usually includes an intercepting ditch; the intercepting ditch is located upstream of the waste rock dump and is used to intercept and deflect surface runoff to prevent it from entering the waste rock dump; the drainage ditch; the drainage ditch network is used to collect and transport water in the waste rock dump and lead it to sedimentation tanks or other treatment facilities; the sedimentation tank is used to remove suspended solids in the wastewater. After the wastewater enters the sedimentation tank, the solid particles settle to the bottom, and the clarified water overflows from the top. Through appropriate drainage structures, the water flow in open-pit mine waste rock dumps can be effectively managed, ecological restoration can be promoted, and environmental pollution can be prevented.

A positioning plate is mounted on the drainage channel, an adjusting mechanism is arranged in the positioning plate, a sleeve that is retracted and contracted by a first spring is arranged on the adjusting mechanism, and a baffle is arranged on the sleeve, and a blocking net is arranged on the baffle, so that debris on the surface of the water flow in the drainage channel can be intercepted to prevent blockage of the drainage channel, and the height of the blocking net can be adjusted by the adjusting mechanism to meet the needs of actual use.

[0004] However, the barrier net of this device can only have a certain interception effect on the debris inside the drainage channel, which is not convenient for personnel to clean up the intercepted debris. In this way, when a lot of debris is accumulated in front of the barrier net, it will affect the drainage effect of the drainage channel. Therefore, a drainage structure based on the ecological restoration of open-pit mine waste rock dump is provided. Utility Model Content

[0022] refer to Figure 1 , Figure 2 A U-shaped frame 9 is fixedly installed on the top surface of the drainage channel 1, and a small winch 10 is fixedly installed on the top surface of the U-shaped frame 9. A wire rope 11 is wound inside the small winch 10 and connected. One end of the wire rope 11 extends to the inner bottom surface of the small winch 10, and one end of the wire rope 11 is fixed to the inside of the lifting ring 8; the small winch 10 is a device for lifting or moving heavy objects. The small winch is usually powered by an electric motor and drives the drum and the wire rope 11 to rotate, so as to facilitate the lifting of heavy objects. The small winch 10 is an existing structure. This application only uses it without improving its structure, so no further elaboration is made here.

[0023] refer to Figure 1 A monitoring camera 12 is fixedly installed on the inner wall of the U-shaped frame 9, and a control box 13 is fixedly installed on the side of the U-shaped frame 9.

[0024] The implementation principle of the embodiment of the drainage structure for ecological restoration of open-pit mine waste rock dump in the present application is as follows: the user first installs the device inside the drainage channel 1, and then intercepts the impurities mixed in the water inside the drainage channel 1 through the provided interception plate 2, and the water flowing inside the drainage channel 1 flows and is discharged normally through the drainage hole 1 3, so that the impurities in the water inside the drainage channel 1 can be prevented from blocking the drainage channel 1 as much as possible;

[0025] When the interception plate 2 intercepts a lot of debris and hinders the flow of water, the personnel starts the motor on the small winch 10 to drive the drum and the wire rope 11 to rotate, so that the wire rope 11 drives the interception plate 2 and the V-shaped plate 4 to move upward. When the interception plate 2 moves upward, the limiting groove 14 is set to limit it so that it will not shake, thereby improving stability. When the interception plate 2 and the V-shaped plate 4 move to a suitable height, the personnel can clean the debris at the bottom of the V-shaped plate 4 through the cleaning hole 5. After the debris is cleaned, the small winch 10 drives the interception plate 2 and the V-shaped plate 4 to reset, so as to facilitate the re-interception of the debris in the water inside the drain 1. The device has a simple structure and is easy to operate. It can effectively intercept the debris in the water inside the drain 1 and is convenient for cleaning the intercepted debris. At the same time, in conjunction with the monitoring camera 12, personnel can remotely monitor the situation of the interception plate 2 inside the drain 1, so that personnel can respond in time.
