Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage treatment, in particular to a rainwater drainage mechanism used for sealing a landfill. Background Art
[0002] With the continuous development of industry, the treatment of industrial solid waste has become a major problem for many companies. At present, the method of disposing industrial solid waste is usually to use landfills to bury the waste. After the industrial solid waste is filled, the landfill needs to be sealed to prevent rainwater from entering the landfill, causing leachate and polluting the surrounding environment.
[0003] After a traditional landfill is filled with garbage, a cover needs to be placed on the landfill to seal the opening of the landfill pool. If it rains, rainwater on the cover will usually flow into the garbage through the gap between the cover and the landfill, which is likely to produce leachate and cause pollution to the surrounding environment.
[0004] Therefore, we propose a rainwater drainage mechanism for landfill closure in order to solve the above-mentioned problems. Utility Model Content
[0005] The utility model aims to solve the problem that rainwater flows into garbage along the gap between the cover plate and the landfill.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rainwater drainage mechanism for landfill closure, comprising a landfill pool and a cover plate covering the opening of the landfill pool, drainage grooves are provided at the edges of the top of the cover plate, and a plurality of drainage outlets are provided at the bottom of the drainage grooves, one of the drainage outlets is provided with a three-way connector, and the remaining multiple drainage outlets are provided with connectors, one end of the three-way connector and the ends of multiple connectors are fixed with connecting pipes, and the multiple connecting pipes are connected by multiple connectors, and the other end of the three-way connector is provided with a drainage pipe for drainage.
[0007] Furthermore: a filter cover is installed on the upper part of the drainage trough, and a plurality of filter holes are opened on the filter cover.
[0008] Further: a fixing seat is fixed on the outer surface of the filter cover, a first bolt is installed inside the fixing seat, and a threaded hole used in conjunction with the first bolt is installed on the cover plate.
[0009] Furthermore: the top of the cover plate is provided with an inclined slope, and the middle part of the top of the cover plate is higher than the part at the edge of the top of the cover plate.
[0010] Furthermore: a plurality of grooves are provided on the top of the landfill pool, and the outer diameter of the grooves is larger than the aperture of the connecting pipe.
[0011] Furthermore: each of the connecting heads is provided with a plurality of clamps, and both ends of the clamps are connected to the cover plate via second bolts.
[0012] Beneficial effects of the utility model:
[0013] The utility model provides a drainage groove at the edge of the top of the cover plate, so that rainwater on the cover plate can flow into the drainage groove, reducing rainwater from directly flowing into the gap between the landfill pool and the cover plate, avoiding the generation of leachate, and reducing pollution to the surrounding environment; a plurality of connecting pipes and drainage pipes are provided at the bottom of the drainage groove, so that the water in the drainage groove can be discharged to the outside of the landfill pool and the cover plate in time, reducing the overflow of the water in the drainage groove due to excessive water.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0021] Embodiments of the present utility model:
[0022] A rainwater drainage mechanism for landfill closure comprises a landfill pool 1, and the landfill pool 1 is pre-buried in the ground. By setting the landfill pool 1, garbage can be put into the landfill pool 1. A cover plate 2 is placed at the opening on the top of the landfill pool 1. The cover plate 2 is set to close the landfill pool 1, thereby reducing the pollution of the garbage in the landfill pool 1 to the external environment. The top of the cover plate 2 is provided with an inclined slope, and the middle position of the top of the cover plate 2 is higher than the position at the top edge of the cover plate 2, so that rainwater on the top of the cover plate 2 can flow to the edge, thereby reducing the accumulation of water on the cover plate 2.
[0023] A drainage groove 3 is provided at the edge of the top of the cover plate 2. Through the setting of the drainage groove 3, rainwater on the cover plate 2 can flow into the drainage groove 3, reducing the rainwater on the cover plate 2 from flowing into the garbage through the gap between the landfill pool 1 and the cover plate 2, avoiding the mixing of rainwater and garbage to produce leachate, and reducing the degree of environmental pollution. A filter cover 10 is provided on the upper part of the drainage groove 3, and a plurality of filter holes are provided on the filter cover 10. Through the setting of the filter cover 10, larger debris can be filtered and larger impurities are reduced from clogging in the drain port 4. A fixing seat 11 is fixed to the outer surface of the filter cover 10. The first bolt 12 passes through the fixing seat 11 and is threadedly connected to a threaded hole (not shown in the figure) provided on the cover plate 2, thereby fixing the filter cover 10.
[0024] Four drainage outlets 4 are fixed at equal intervals at the bottom of the drainage trough 3, one of the drainage outlets 4 is equipped with a three-way connector 5, and the other three drainage outlets 4 are each provided with a connector 6, one end of the three-way connector 5 and one end of the multiple connectors 6 are each equipped with a connecting pipe 7, and one end of the multiple connecting pipes 7 is connected to the same multi-connector 8, which is a four-way connector, and the other end of the three-way connector 5 is equipped with a drainage pipe 9. Through the arrangement of the connecting pipe 7 and the drainage pipe 9, rainwater in the drainage trough 3 can be discharged in time, reducing the overflow of rainwater in the drainage trough 3.
[0025] A plurality of grooves 13 are provided on the top of the landfill pool 1 , and the outer diameter of the groove 13 is larger than the outer diameter of the connecting pipe 7 . Through the provision of the grooves 13 , a plurality of connecting pipes 7 can be placed in the grooves 13 , respectively.
[0026] Each connector 6 is provided with a plurality of clamps 14 , and both ends of the clamps 14 are connected to the cover plate 2 via second bolts 15 . The arrangement of the clamps 14 serves to fix the connecting pipe 7 .
[0027] If rainwater falls on the upper part of the cover plate 2, since the upper part of the cover plate 2 is provided with an inclined slope, the rainwater on the cover plate 2 can flow into the drainage trough 3, and larger impurities (for example, leaves) can be filtered through the filter cover 10. The rainwater in the drainage trough 3 flows to the three-way connector 5 and the multiple drainage pipes 9 through multiple drainage ports 4 respectively. The rainwater in the multiple connectors 6 all flows into the drainage pipe 9 through the connecting pipe 7, and the rainwater in the three-way connector 5 directly flows into the drainage pipe 9. The rainwater is discharged to the outside of the landfill pool 1 and the cover plate 2 through the drainage pipe 9, thereby reducing the rainwater entering the landfill pool 1 from the gap between the landfill pool 1 and the cover plate 2.
