Abstract
Description
Technical Field
[0001] This utility model relates to a drainage device, and more particularly to a drainage device for open-pit mining, belonging to the technical field of drainage equipment. Background Technology
[0002] Open-pit mining involves removing the topsoil and surrounding rock from the ore body, transporting the waste rock to a spoil heap, and directly extracting ore from the exposed ore body. Open-pit mining is superior to underground mining when the ore body is shallowly buried or has surface outcrops.
[0003] During the mining process, groundwater and surface water from rock strata accumulate in the mine pit. However, existing drainage systems in open-pit mines often have difficulty controlling the immersion depth of the drainage pipes. If the immersion depth is too shallow, it is difficult to drain the water from the mine, while if the immersion depth is too deep, the pipes can become embedded in the ore layer and easily become blocked.
[0004] In view of the problem that the immersion depth of drainage pipes is often difficult to control when drainage devices are used in open-pit mines, this utility model proposes a new solution. Utility Model Content
[0005] The main purpose of this utility model is to provide a drainage device for open-pit mining in order to overcome the shortcomings of the existing technology.
[0006] The objective of this utility model can be achieved by adopting the following technical solution:
[0007] A drainage device for open-pit mining includes a float plate with a drainage mechanism on its inner side. The drainage mechanism includes a pumping pipe movably installed on the inner side of the float plate, a connecting pipe connected to the top outer wall of the pumping pipe, and a positioning mechanism slidably connected to the float plate. The positioning mechanism includes multiple insertion rods slidably connected to the float plate, a positioning plate installed between the multiple insertion rods, a filter frame connected to the bottom of the float plate, and the bottom end of the pumping pipe located inside the filter frame.
[0008] Preferably, there are three cutting rods arranged in a triangular pattern.
[0009] Preferably, the bottom end of the cutting rod is provided with a pointed tip, and a support plate located below the positioning plate is connected to the outer wall of the bottom of the cutting rod.
[0010] Preferably, the float plate has a sliding hole that is slidably connected to the cutting rod, and the positioning plate is connected to a sliding tube that cooperates with the cutting rod.
[0011] Preferably, the top of the float is connected to a lifting mechanism that cooperates with the pumping pipe. The lifting mechanism includes a mounting plate installed on the outer wall of the pumping pipe, and an electric lifting rod is installed between the float and the mounting plate.
[0012] Preferably, the bottom surface of the filter frame has a first through hole in the middle that cooperates with the water pumping pipe, and a cover plate is rotatably installed on the bottom surface of the filter frame.
[0013] Preferably, the positioning plate has a second through hole in the middle that cooperates with the water pumping pipe.
[0014] Preferably, a rotating sleeve located on one side of the first through hole is fixedly connected to the bottom surface of the filter frame, and a rotating rod that rotates with the rotating sleeve is connected to one side of the cover plate, and a torsion spring is installed on the rotating rod.
[0015] Preferably, the end of the connecting pipe furthest from the pumping pipe is connected to a flange.
[0016] Preferably, the outer wall at the bottom of the pumping pipe is provided with a water-permeable hole.
[0017] The beneficial technical effects of this utility model are as follows: According to the drainage device for open-pit mining of this utility model, the drainage mechanism, installed on the float, can float directly on the water surface for pumping. The drainage mechanism automatically lowers as the water level drops, ensuring the pumping pipe remains at a constant depth without manual height adjustment. The pumping pipe also avoids direct embedding into the mineral layer, preventing blockages. The positioning mechanism prevents the float from drifting arbitrarily and affecting drainage. Multiple insertion rods are slidably connected via the positioning plate, allowing for fixation on uneven water surfaces. The filter frame enables filtration, preventing blockages.

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0026] like Figures 1-6 As shown, the drainage device for open-pit mining provided in this embodiment includes a float plate 1, a drainage mechanism 2 provided on the inner side of the float plate 1, a water pumping pipe 3 movably installed on the inner side of the float plate 1, a connecting pipe 4 connected to the top outer wall of the water pumping pipe 3, and a positioning mechanism 5 slidably connected to the float plate 1. The positioning mechanism 5 includes a plurality of insertion rods 6 slidably connected to the float plate 1, a positioning plate 7 installed between the plurality of insertion rods 6, a filter frame 8 connected to the bottom of the float plate 1, and the bottom end of the water pumping pipe 3 located inside the filter frame 8. With the setup of float plate 1 and drainage mechanism 2, the drainage mechanism 2 is installed on float plate 1 and can float directly on the water surface to pump water. The drainage mechanism 2 will automatically lower as the water level drops, and the water pumping pipe 3 can always maintain the depth of the water without manual height adjustment. The water pumping pipe 3 will not directly embed into the mineral layer and cause blockage. With the setup of positioning mechanism 5, float plate 1 can be prevented from drifting randomly and affecting drainage. Multiple insertion rods 6 are slidably connected by positioning plate 7, which can be used to fix uneven bottom surfaces. With the setup of filter frame 8, filtration can be performed to prevent blockage.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, three cutting rods 6 are arranged in a triangular pattern. Each cutting rod 6 has a pointed end. A support plate 9, located below the positioning plate 7, is connected to the outer wall of the bottom of the cutting rod 6. A sliding hole 10 is provided on the float plate 1 to slide with the cutting rod 6. A sliding tube 16, which mates with the cutting rod 6, is connected to the positioning plate 7. The three cutting rods 6, arranged in a triangular pattern, provide stable support. The pointed ends of the cutting rods facilitate insertion, and the support plate 9 prevents the positioning plate 7 from falling off.
[0028] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, the top of the float 1 is connected to a lifting mechanism that cooperates with the water pumping pipe 3. The lifting mechanism includes a mounting plate 11 installed on the outer wall of the water pumping pipe 3, and an electric lifting rod 12 is installed between the float 1 and the mounting plate 11. By setting up the lifting mechanism, the height of the water pumping pipe 3 can be adjusted up and down, thereby adjusting the distance by which the bottom end of the water pumping pipe 3 extends out of the float 1, thus facilitating drainage.
[0029] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, a first through hole 13 is provided in the middle of the bottom surface of the filter frame 8 to cooperate with the water pumping pipe 3. A cover plate 14 is rotatably installed on the bottom surface of the filter frame 8. A second through hole 15 is provided in the middle of the positioning plate 7 to cooperate with the water pumping pipe 3. A rotating sleeve 17 is fixedly connected to the bottom surface of the filter frame 8 on one side of the first through hole 13. A rotating rod 18 that rotatably cooperates with the rotating sleeve 17 is connected to one side of the cover plate 14. A torsion spring 19 is installed on the rotating rod 18. With the first through hole 13 and the second through hole 15, when the water level is low and the float 1 cannot descend, the electric lifting rod 12 can drive the water pumping pipe 3 through the first through hole 13 and the second through hole 15 to pump water from the lower level. With the torsion spring 19 and the cover plate 14, it can be ensured that the cover plate 14 automatically covers the first through hole 13 when no external force is applied.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, a flange 20 is connected to the end of the connecting pipe 4 away from the pumping pipe 3, and a water permeable hole 21 is provided on the outer wall of the bottom of the pumping pipe 3. The flange 20 facilitates connection to an external water pump via a flexible hose, and the water permeable hole 21 enables some filtration.
[0031] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the drainage device for open-pit mining provided in this embodiment is as follows:
[0032] Step 1: Select the pumping location, install three insert rods 6 and positioning plate 7, and then install float plate 1 and drainage mechanism 2 so that float plate 1 floats on the water surface;
[0033] Step 2: Connect the external water pump to the connecting pipe 4 through the external water pipe, and start the external water pump to drain the water;
[0034] Step 3: When the water level is low and the float 1 cannot descend, start the electric lifting rod 12 to drive the water pumping pipe 3 through the first through hole 13 to open the cover plate 14, and through the second through hole 15 to pump water.

Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
