DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-Figure 7 As shown:

[0026] The present embodiment provides a water collection, water saving and seepage control device for a slope in a mining area, including a guide plate 1, a carrier 2 is installed in front of the guide plate 1, a guide sleeve 27 is fixed in the middle of the carrier 2, a guide column 3 is installed in the guide sleeve 27, a truss 4 is fixed on the top of the guide plate 1, the truss 4 is provided with a through hole 5, the through hole 5 is connected from top to bottom, and an isolation net 6 covering the through hole 5 is installed on the top surface of the truss 4, a water tank 7 is provided in front of the guide plate 1, rainwater falls on the isolation net 6, is filtered by the isolation net 6 and then leaks into the water tank 7, and the water tank 7 is connected to On the top of the guide column 3, the water tank 7 can follow the guide column 3 to move up and down. The bottom end of the guide column 3 passes through the bottom of the guide sleeve 27. A set 8 is fixed to the bottom end of the guide column 3. The set 8 is located below the carrier 2. A plug hole 9 is provided on the set 8. A suspension rod 10 is inserted into the plug hole 9. A first tension spring 11 is connected between the end of the suspension rod 10 and the carrier 2. When the water tank 7 descends, it pushes the guide column 3 to descend, and the guide column 3 pushes the set 8 to descend. The set 8 and the suspension rod 10 drag the first tension spring 11 downward, so that the first tension spring 11 is elastically stretched;

[0027] The top of the water tank 7 opens upward and is directly opposite to the bottom of the through opening 5. A cleaning rod 12 is installed in the middle of the top surface of the isolation net 6. A pull rope 13 is connected to the cleaning rod 12. The other end of the pull rope 13 extends downward from the side of the truss 4 and is connected to the water tank 7. When the water tank 7 descends, the pull rope 13 is dragged by the pull rope 13, and the cleaning rod 12 is dragged by the pull rope 13 from the middle of the isolation net 6 to the end of the isolation net 6.

[0028] The water tank 7 is at two symmetrical locations on the left and right, the pull ropes 13 are two symmetrical pull ropes 13 on the left and right, and the cleaning rods 12 are two symmetrical pull ropes 13 on the left and right. The pull rope 13 on the left extends upward from the left side of the truss 4 and is connected to the cleaning rod 12 on the left. The pull rope 13 on the right extends upward from the right side of the truss 4 and is connected to the cleaning rod 12 on the right. A second tension spring 26 is connected between the two cleaning rods 12.

[0029] The socket 9 is opened from the left side of the kit 8 to the right side of the kit 8, and the suspension rod 10 is inserted from the left side of the socket 9 to the right side of the socket 9. The left and right ends of the suspension rod 10 are symmetrical on the left and right sides of the kit 8. There are two first tension springs 11 on the left and right. The bottom ends of the two first tension springs 11 are respectively connected to the left and right ends of the suspension rod 10, and the top ends of the two first tension springs 11 are upwardly connected to the carrier 2.

[0030] A connecting plate 14 is installed between the left and right water tanks 7 , and the top end of the guide column 3 is connected to the middle position of the connecting plate 14 .

[0031] The left and right ends of the truss 4 are each connected with a discharge plate 15, and the discharge plate 15 gradually tilts outward from the top downward, and the carrier 2 is a U-shaped bent part, so that the left and right ends of the carrier 2 are provided with a covering portion 16 extending upward to near the bottom of the two discharge plates 15, and the two discharge plates 15 are both provided with a wire opening 25, and the pull rope 13 passes through the wire opening 25.

[0032] Vertical guide rails 17 are arranged on the inner surfaces of the left and right covers 16, and a support rod 18 is connected to the bottom surfaces of the two water tanks 7. The bottom ends of the two support rods 18 are inclined outward and are equipped with casters 19, which are rollingly mounted on the guide rails 17 on the same side. The lifting and lowering of the two water tanks 7 is more stable.

[0033] An inlay opening is provided on the bottom surface of the water tank 7, in which a rubber plate 20 is fixed, and a tight hole 21 is provided on the rubber plate 20. A conical rod 22 is fixed on the bottom surface of the carrier 2, and the tight hole 21 corresponds to the top of the conical rod 22. When the water tank 7 is lowered to press the tight hole 21 onto the conical rod 22, the conical rod 22 is inserted into the tight hole 21. The conical rod 22 is a hollow structure, and water holes 23 are provided at the top and bottom ends thereof. When the top end of the conical rod 22 is inserted into the tight hole 21, rainwater in the water tank 7 leaks into the cavity of the conical rod 22, and then leaks outward from the water hole 23 on the bottom end of the conical rod 22.

[0034] The carrier 2 is provided with a seepage hole 24 , and the seepage hole 24 is close to the cone piercing rod 22 .

[0035] When in use, the guide plate 1 is fixed on the slope of the mining area, and the isolation net 6 is located above. Rainwater falls on the isolation net 6, and after fine filtration by the isolation net 6, the water falls into the two water tanks 7 for collection. Filter nets can also be set in the two water tanks 7 for further filtration. When the water weight in the two water tanks 7 is greater than the pulling force of the two first tension springs 11 on the two suspension rods 10, the two water tanks 7 descend, and at the same time, the connecting plate 14 is used to push the guide column 3 to descend along the guide sleeve 27, and the guide column 3 drives the set 8 to descend, and the set 8 drives the suspension rod 10 to descend, and the two first tension springs 11 are dragged downward by the two ends of the suspension rod 10, and the two first tension springs 11 are elastically stretched. At this time, two technical effects will be produced. One technical effect is that the tight holes 21 on the two water tanks 7 will fall on the conical thorn rod 22, and the tight holes 21 will be expanded by using the taper of the conical thorn rod 22, and the water in the two water tanks 7 will flow into the top of the conical thorn rod from the water hole 23. The water in the water tank 7 is discharged into the lumen of the water tank 7, and then discharged to the carrier 2 from the bottom end of the water hole 23, and finally slowly discharged downward through the seepage hole 24 on the carrier 2; another technical effect is that when the two water tanks 7 descend, the left and right pull ropes 13 will be dragged downward at the same time, and the top ends of the two pull ropes 13 will drag the two cleaning rods 12 at the same time, moving from the middle of the truss 4 to the two ends of the truss 4, and the second tension spring 26 is elastically stretched. The bottom surfaces of the two cleaning rods 12 are actually attached to the isolation net 6. Therefore, when the two cleaning rods 12 move from the middle of the isolation net 6 to the two ends of the isolation net 6, it is equivalent to cleaning the impurities such as leaves intercepted on the isolation net 6 to one side, and the cleaned impurities are slid to the two sides of the device by the discharge plate 15 at a long distance. It can be seen that even if the isolation net 6 is located at a higher position, there is no need to manually clean the impurities, and after the impurities on the isolation net 6 are cleaned, the mesh of the isolation net 6 is kept connected from top to bottom. It can be seen from the above-mentioned action principle that the implementation of the latter technical effect (automatic cleaning of impurities on the isolation net 6) is based on the former technical effect (automatic discharge of water in the water tank 7), utilizing natural conditions, without the need for human operation, and without the need to add complex mechanical structures and automated power equipment.

[0036] It is necessary to further point out that: the water tank 7 falls on the conical thorn rod 22, and the conical thorn rod 22 penetrates into the tight hole 21 to expand the tight hole 21, and then extends the top of the water hole 23 into the box. At this time, the caster 19 rolls to the bottom end of the guide rail 17 and is restricted and no longer descends, and the support rod 18 is used to restrict the bottom surface of the water tank 7 above the carrier 2, so as to expose the bottom end of the water hole 23. At this time, the water in the water tank 7 enters the tubular cavity of the conical thorn rod 22 through the top of the water hole 23, and is finally discharged to the carrier 2 from the bottom end of the water hole 23. At this time, not only the water tank 7 is used to drain water slowly, but also the water tank 7 is used to slide rainwater from the high end of the guide plate 1 (equivalent to the high end of the mine slope) to the low end of the guide plate 1 (equivalent to the low end of the mine slope). First, the water flow originally flowing through the slope is protected by the guide plate 1 to avoid landslide. Secondly, the water flow is concentrated in the form of sliding from high points to low points for slow discharge, which plays a protective role on the slopes of the mining area.

[0037] As the amount of rain decreases, or as the amount of water in the water tank 7 is discharged to a certain extent after a sunny day, the first tension spring 11 rebounds and shortens upward, and at the same time, the suspension rod 10 is used to drag the kit 8 upward again, and the guide column 3 is lifted upward by the kit 8, and the connecting plate 14 is pushed upward by the top of the guide column 3, and the two water tanks 7 are lifted and reset by the connecting plate 14. At the same time, the second tension spring 26 elastically shortens, and while shortening, the two cleaning rods 12 are reset, waiting for the next rainy day, the water tank 7 repeats the rainwater collection and slow discharge work, and the cleaning rod 12 repeats the synchronous cleaning work on the isolation net 6.

[0038] It is necessary to further point out that: in addition to using the inner side surface to install the guide rail 17 for guiding the caster 19, the two cover parts 16 also use the outer side surface to assist the discharge plate 15, so that the impurities cleaned off the isolation net 6 are blocked and prevented from falling onto the guide plate 1. The bottom end of the guide rail 17 exceeds the bottom end of the cover part 16 to reach the bottom of the carrier 2, and a limit plate is provided at the bottom end of the guide rail 17 to limit the descending stroke of the caster 19. When the tight hole 21 on the water tank 7 falls on the cone thorn rod 22, and the bottom surface of the water tank 7 uses the water hole 23 on the cone thorn rod 22 to drain water, the caster 19 reaches the bottom end of the guide rail 17 and the stroke is limited. At this time, there is a gap between the bottom surface of the water tank 7 and the carrier 2 for drainage.

[0039] What needs to be further pointed out is: Figure 5 , Figure 7 As shown, the seepage hole 24 is actually a rectangular gap opened on the carrier 2. When the water tank 7 is lowered to the restricted position, the support rod 18 will be inserted into the seepage hole 24. The seepage hole 24 does not affect the water tank 7 to drain water outwards through the water hole 23 on the cone rod 22, and at the same time, it provides a descending space for the support rod 18. The setting of the support rod 18 and the caster 19 makes the lifting and lowering action of the water tank 7 more stable.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.
