[0020] (1) This case sets up: an adjustable cleaning structure, thereby solving the problem that the open-pit mine drainage device in the above case adopts a filter screen to prevent mud and sand from being blocked, but the filter screen is prone to blockage during long-term use, thereby affecting the drainage effect. When the drainage device body is working to drain water, the suction force generated during the operation of the drainage device body drives the water to force the connecting spring and the through-hole plate to move toward the inside of the connecting tube. When the through-hole plate is forced to move toward the inside of the connecting tube, it drives the thorn rod to move synchronously.

When the baffle rotates synchronously, the mud and particles carried by the water flow come into contact with the baffle. At this time, the mud and particles collide with each other or the rotational force of the baffle remains on both sides of the baffle. When the baffle stops working, the mud and particles fall to the bottom of the connecting frame and are discharged through the outlet pipe below the connecting frame.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a drainage device for open-pit mines to prevent silt blockage, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , it includes a drainage structure 1. The drainage structure 1 includes a drainage device body 101 as the main body. The drainage device body 101 is fixedly connected to the connection frame 103 in an inlaid manner through a water inlet pipe 102. At the same time, an installation bearing 104 is fixedly installed inside the connection frame 103 through a connecting rod. A connecting shaft 105 passes through the installation bearing 104. One end of the connecting shaft 105 is fixedly connected to an impeller 106, and the other end of the connecting shaft 105 is fixedly connected to a through-hole disc 107. Among them, the components of the drainage device body 101 are all installed according to the components in the comparative document. When using the components in the comparative document to set up the drainage device body 101, it can effectively achieve the normal drainage effect. And the above components form a driving rotation structure. When using the above components to form a driving rotation structure, it can effectively rotate and disperse and rotate and strike the nearby sediment and particles.

[0031] In the above solution, further, a baffle 108 is fixedly welded on the surface of the through-hole disc 107, and the baffle 108 is arc-shaped. When the above components are arc-shaped, it can effectively ensure that when the above components rotate under force, they can rotate and strike the sediment and particles transported nearby. The connection frame 103 is fixedly connected with a filter net 109 in an inlaid manner.

[0032] As Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , an adjustment and cleaning structure 2 is provided inside the drainage structure 1. The adjustment and cleaning structure 2 includes a connection cylinder 201 with an installation groove 202 opened inside. A slide rod 203 passing through a slider 204 is fixed inside the installation groove 202. At the same time, a through-hole plate 205 is fixed between the sliders 204.

[0033] In the above solution, further, a connection spring 206 is fixed on one side of the through-hole plate 205. The connection shape between the through-hole plate 205 and the connection spring 206 is in a "sub" shape. By setting the above components in a "sub" shape, it not only reflects the practicality of the installation of the above components, but also reflects the elastic connection of the installation of the above two. And when the connection shape of the above two is in a "sub" shape, it reflects the axial and longitudinal axis symmetry of the installation of the above two, and also reflects the elastic adjustment and elastic recovery of the installation of the above two. The connection spring 206 is fixedly connected to the connection cylinder 201 through another through-hole plate 205. At the same time, a thorn rod 207 is fixed on the other side of the through-hole plate 205.

[0034] In the above solution, further, the connection cylinder 201 is fixedly wrapped around one end of the water inlet pipe 102 through an installation hole, and the connection cylinder 201 is in a U-shaped cylinder setting.

[0035] In the above scheme, when the drainage device body 101 is working to drain water, the suction force generated during the operation of the drainage device body 101 drives the water to force the connecting spring 206 and the through-hole plate 205 to move toward the inside of the connecting cylinder 201. When the through-hole plate 205 is forced to move toward the inside of the connecting cylinder 201, it drives the thorn rod 207 to move synchronously. When the thorn rod 207 contacts the filter screen 109, the thorn rod 207 pierces the particles and sediment stuck in the filter screen 109 to ensure the normal interception and filtration of the filter screen 109. When the impeller 106 is driven by the flow to rotate, the through-hole disk 107 and the baffle 108 are driven to rotate synchronously through the connecting shaft 105. When the baffle 108 is driven to rotate synchronously, the silt and particles carried by the water flow contact the baffle 108. At this time, the silt and particles collide with the force or the rotational force of the baffle 108 on the silt and particles remains on both sides of the baffle 108. When the baffle 108 stops working, the silt and particles fall to the bottom of the connecting frame 103 and are discharged through the outlet pipe below the connecting frame 103.
