Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment technology, specifically to a water supply and drainage device for landfills. Background Technology
[0002] Due to limitations in environmental awareness and technology, municipal solid waste landfills currently employ relatively simple and inefficient methods. However, with increasing environmental awareness and technological advancements, landfills are gradually evolving into more scientific and standardized sanitary landfills. Sanitary landfills require comprehensive water supply and drainage systems to ensure their normal operation and environmental protection.
[0003] Patent CN215669709U discloses a landfill closure drainage system with good drainage performance, including a landfill area and a permeable layer. The permeable layer is located at the bottom of the landfill area, and several water collection branch pipes are located at the bottom of the permeable layer. A water collection tank is located at the bottom of each water collection branch pipe, and the bottom of the water collection tank is connected to a water collection trough via a water collection pipe. A drain pipe is located on one side of the water collection trough, and a second impermeable layer is located at the bottom of the water collection trough. An air guide pipe is located in the landfill area, passing through the surface of the landfill area and the waterproofing device. This utility model provides a landfill closure drainage system with good drainage performance. Its beneficial effects are that the above-mentioned landfill area, permeable layer, impermeable layer, water collection trough, water collection tank, water collection pipe, and water collection branch pipes work together to achieve timely discharge of wastewater generated from the landfill, preventing wastewater accumulation. Furthermore, the impermeable layer at the bottom prevents wastewater from flowing into the ground and contaminating groundwater.
[0004] However, the above technology still has the following problems: during the drainage process of landfill waste, it is easy to cause blockage of drainage pipes. After the waste is landfilled, it is necessary to dig out the treated waste for sorting and processing. The above technology is similar to the existing technology. In addition, during the digging process, it is easy to damage the impermeable layer and drainage pipes. If the landfill needs to be rearranged and constructed before the landfill is completed, it will be time-consuming, labor-intensive and wasteful of resources. Utility Model Content

A threaded groove is opened at the upper end of the support rod, and a support plate is threadedly connected to the threaded groove. A fixed seat is fixedly connected to the support plate, and a laser rangefinder is detachably connected to the fixed seat. A circular hole matching the laser rangefinder is opened on the support plate, and a protective mechanism is fixedly connected to the support plate. A fixed plate is fixedly connected to the upper end of the metal mesh, and a drainage mechanism is fixedly connected to the fixed plate. A suspended ball is slidably connected to the support rod.
[0007] Furthermore, the fixing base includes a rectangular baffle fixedly connected to the support plate, and two tightening bolts are threadedly connected to the rectangular baffle. Each of the two tightening bolts has a pressing plate fixedly connected to its front end.
[0008] Furthermore, a rubber anti-slip and wear-resistant pad is fixedly connected to the extrusion plate.

[0010] Furthermore, the folding barrel is made of TPE.
[0011] Furthermore, the drainage mechanism includes a drainage pump fixedly connected to a fixed plate, with an inlet pipe and an outlet pipe fixedly connected to the drainage pump, the lower end of the inlet pipe being located inside the water collection tank.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1 to 4 A water supply and drainage device for a landfill includes a landfill area 1, several water collection pits dug in the landfill area 1, and an impermeable layer 2 laid in both the landfill area 1 and the water collection pits. A water collection bucket 3 is placed in the water collection pit, and a cylindrical metal mesh 4 is fixedly connected to the top of the water collection bucket 3. A support rod 5 is fixedly connected to the middle part of the water collection bucket 3. A threaded groove 6 is opened at the upper end of the support rod 5, and a support plate 7 is threadedly connected to the threaded groove 6. A fixed seat is fixedly connected to the support plate 7, and a laser rangefinder 8 is detachably connected to the fixed seat. A circular hole 9 matching the laser rangefinder 8 is opened on the support plate 7, and a protective mechanism is fixedly connected to the support plate 7. A fixed plate 10 is fixedly connected to the upper end of the metal mesh 4, and a drainage mechanism is fixedly connected to the fixed plate 10. A suspended ball 24 is slidably connected to the support rod 5.
[0021] The water supply and drainage device for landfills in this utility model is structurally similar to existing landfill closure drainage systems with good drainage performance. For example, patent CN215669709U discloses a landfill closure drainage system with good drainage performance. The main improvement of this utility model is that the pipeline runs above the landfill area 1, avoiding pipeline blockage and preventing damage to the pipeline during garbage excavation. Figures 1 to 4As shown, the water supply and drainage device for landfills in this utility model, when in use, first, the suspended ball 24 is fitted onto the support rod 5, then the laser rangefinder 8 is placed inside the rectangular baffle 11, and the tightening bolt 12 is screwed on so that the pressing plate 13 is in contact with the laser rangefinder 8 and presses the laser rangefinder 8 to fix it. The laser rangefinder 8 can be removed by reversing the operation. At the same time, the folding bucket 20 is connected to the internal threaded tube 18 through the threaded rod 19. The rotating plate 17 is rotated so that the folding bucket 20 is directly above the laser rangefinder 8. The folding bucket 20 is unfolded downwards to cover the laser rangefinder 8, thereby controlling the laser rangefinder. The rangefinder 8 is protected from rain, etc. The folding bucket 20 can be removed by reversing the operation. Since there are multiple water collection pits dug inside the landfill area 1, and the water collection bucket 3 is installed in the water collection pit, the water in the landfill waste will flow into the water collection bucket 3 under the interception effect of the cylindrical metal mesh 4 with small aperture. The suspended ball 24 will move upward under the action of buoyancy, thereby changing the distance measured by the laser rangefinder 8, and thus transmitting the signal to start the drainage pump 21. The drainage pump 21 starts to drain the water inside the water collection bucket 3. When the water level is low, the laser rangefinder 8 will transmit the signal to shut off the drainage pump 21, thereby stopping the drainage.
[0022] It should be noted that: multiple water collection pits are set up in landfill area 1, so that multiple water collection buckets 3 can be placed. Since the terrain is basically the same, there are gaps between the garbage inside landfill area 1, and water can still slowly seep into other areas. It is not necessary for all laser rangefinders 8 to work at the same time. They can be used in intervals, according to shifts, using one laser rangefinder 8 and drainage pump 21 on one water collection bucket 3. This satisfies the drainage needs and also extends the service life of the laser rangefinder 8 and drainage pump 21.
[0023] like Figure 3 As shown, the fixed base includes a rectangular baffle 11 fixedly connected to the support plate 7. Two tightening bolts 12 are threadedly connected to the rectangular baffle 11, and a pressing plate 13 is fixedly connected to the front end of each of the two tightening bolts 12.
[0024] Specifically, first, the levitation ball 24 is placed on the support rod 5, then the laser rangefinder 8 is placed inside the rectangular baffle 11, and the tightening bolt 12 is tightened so that the pressing plate 13 is in contact with the laser rangefinder 8 and presses the laser rangefinder 8 to fix it. The laser rangefinder 8 can be removed by repeating the operation.
[0025] like Figure 3 As shown, a rubber anti-slip and wear-resistant pad 14 is fixedly connected to the extrusion plate 13.
[0026] Specifically, the rubber anti-slip and wear-resistant pad 14 can enhance the fixing effect and reduce damage to the laser rangefinder 8.
[0027] like Figure 4 As shown, the protective mechanism includes a connecting rod 15 fixedly connected to the support plate 7. Two parallel limiting plates 16 are fixedly connected to the connecting rod 15. A rotating plate 17 is rotatably connected to the connecting rod 15. An internally threaded tube 18 is fixedly connected to the front end of the rotating plate 17. A threaded rod 19 is threadedly connected to the internally threaded tube 18. A folding barrel 20 is fixedly connected to the lower end of the threaded rod 19.
[0028] Specifically, the folding bucket 20 is connected to the internal threaded tube 18 via the threaded rod 19. The rotating plate 17 is rotated so that the folding bucket 20 is positioned directly above the laser rangefinder 8. The folding bucket 20 is then unfolded downwards to cover the laser rangefinder 8, thus providing rain protection for the laser rangefinder 8. The folding bucket 20 can be removed by performing the reverse operation.
[0029] like Figure 4 As shown, the folding barrel 20 is made of TPE.
[0030] Specifically, TPE (thermoplastic elastomer) materials are particularly suitable for folded parts because they have good elasticity and durability, allowing for multiple folds without easily being damaged.
[0031] like Figure 2 As shown, the drainage mechanism includes a drainage pump 21 fixedly connected to the fixed plate 10. The drainage pump 21 is fixedly connected to an inlet pipe 22 and an outlet pipe 23. The lower end of the inlet pipe 22 is located inside the water collection tank 3.
[0032] Specifically, the water in the landfill waste flows into the collection bucket 3 due to the interception effect of the cylindrical metal mesh 4 with a small aperture. The suspended ball 24 moves upward under the action of buoyancy, which reduces the distance measured by the laser rangefinder 8 and transmits the signal to start the drainage pump 21. The drainage pump 21 starts to drain the water inside the collection bucket 3. When the water level drops, the laser rangefinder 8 transmits the signal to shut down the drainage pump 21 and stop the drainage.
[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
