Meanwhile, the foam board is in interference fit with the inner wall of the plastic baffle. In addition, in order to increase the speed of rainwater infiltration on the surface of the floating block 6 and reduce accumulated water, as shown in fig. 1 and shown in the drawing, a plurality of through holes 18 are formed in the surface of the foam board, the through holes 18 are arranged along the height direction of the floating block 6, and the diameter of the through holes 18 is gradually reduced from large to small from one end close to the sunken drainage groove 3 to the other end. At this moment, the through hole 18 is arranged in a funnel shape with a large upper part and a small lower part, so that the phenomenon that a large amount of water below the floating block 6 is upwards reverse-infiltrated can be effectively reduced.
In order to facilitate the planting of plants, as shown in fig. 1 and 2, a plurality of planting holes 7 are formed in the floating block 6, the planting holes 7 are filled with soil layers, and SAP particles (not shown in the figure) with high water absorption values containing plant nutrient solutions are arranged in the soil layers. Wherein the plant nutrient solution adopts potassium sulfate compound fertilizer. The greening plants are planted in the soil layer, and nutrient components required by plant growth can be obtained by absorbing the plant nutrient solution in the soil. In addition, in order to facilitate the plants to absorb water, as shown in fig. 1 and fig. 2, a water absorption rod 16 is arranged in the planting hole 7, the water absorption rod is made of sponge material, one end of the water absorption rod 16 upwards penetrates through the foam board towards the planting groove direction and is fixed on the foam board through knotting, meanwhile, the water absorption rod 16 is in direct contact with the soil layer, and the other end of the water absorption rod 16 downwards extends to the bottom of the planting water tank 2 and is immersed in the water body. From this through the adsorption of sponge, can be with being located the water conservancy diversion of planting basin 2 to plant the inslot to for vegetation provides required moisture, and the existence of the water in the basin can not cause negative effect to the normal growth of plant yet.
As shown in fig. 2, in order to facilitate the control of the water level in the planting water tank 2, the sinking type drain tank 3 is provided with a flip plug 8 at an end close to the planting water tank 2. Wherein, flip stopper 8 has a cylindrical shape's pivot 9 along its diameter welding, and the middle part of pivot 9 is along welding on flip stopper 8's diapire, and the both ends of pivot 9 then outwards stand out outside flip stopper 8 along flip stopper 8's diameter, and the both ends of pivot 9 rotate respectively simultaneously and connect on two relative inner walls that set up of formula of sinking water drainage tank 3, and the operator can realize opening and shutting drain pipe 5's effect through flip stopper 8 from this.
Meanwhile, as shown in fig. 1 and 2, an annular groove (not marked in the figures) is formed in the circumferential side wall of the flip plug 8, an elastic rubber ring 12 is sleeved in the annular groove, and the rubber ring 12 protrudes out of the annular groove at a side far away from the annular groove. When the sewer pipe is covered, the rubber ring 12 is abutted against the inner wall of the sunken drainage groove 3. In addition, as shown in fig. 1 and 2, an inverted U-shaped engaging lug is welded at the edge of the flip plug 8 away from the rotating shaft 9, a rope 10 is bound on the engaging lug, a U-shaped engaging lug is integrally connected to the floating ball, and the other end of the rope 10 is bound on the engaging lug of the floating ball. In addition, a torsion spring 11 is sleeved on the rotating shaft 9, the middle part of the torsion spring 11 is fixedly arranged on the bottom wall of the flip plug 8, and two ends of the torsion spring are wound on the rotating shaft 9 and are welded and fixed with the end part of the rotating shaft 9. Therefore, when the torsion spring 11 is in a natural state, the flip plug 8 is sealed and covered on the inner wall of the sunken drainage groove 3, and the automatic closing of the flip plug 8 can be realized.
As shown in fig. 1 and 2, when the water level in the planting water tank 2 rises in rainy season, the floating block 6 rises along with the water level, and after the floating block 6 rises to a certain height, the buoyancy of the floating block 6 is larger than the torsional force of the torsion spring 11, the flip cover plug 8 turns around the rotating shaft 9, so that the end with the rope 10 turns upwards, and at the moment, the pipe opening of the drain pipe 5 is opened, so that the water body in the planting water tank 2 is discharged into the municipal rainwater pipe along the drain pipe 5, and the directional drainage of rainwater is realized. Meanwhile, the water level in the planting water tank 2 is lowered, the floating block 6 moves downwards along with the lowering, when the pulling force of the buoyancy on the rope 10 is smaller than the torsional force of the torsion spring 11, the flip cover plug 8 is restored to the horizontal state again under the action of the torsion spring 11 to close the drain pipe 5, and therefore the effect of automatically controlling the water level can be achieved.
In order to reduce the odor overflow in the drain pipe 5, as shown in fig. 2, a baffle plate with a protrusion 13 at the center is fixedly arranged on the inner wall of the sunken drain tank 3, a drain opening 14 is arranged at the center of the protrusion 13, the drain opening 14 is communicated with the drain pipe 5, and the protrusion 13 is positioned at the center part below the rotating shaft 9. Meanwhile, the flip plug 8 is provided with an elastic arc-shaped plate 15 on one side close to the sunken drainage groove 3, the elastic arc-shaped plate 15 is hemispherical, the center of the elastic arc-shaped plate 15 is fixedly arranged on the flip plug 8, two ends of the elastic arc-shaped plate 15 are bent towards the sunken drainage groove 3, and at the moment, the horizontal height of two ends of the elastic arc-shaped plate 15 is lower than that of the bulge 13 in the covering state of the flip plug 8. Therefore, when water is accumulated between the baffle plate and the bulge 13, a water seal state is formed between the baffle plate and the elastic arc-shaped plate 15, so that the phenomenon that the odor in the drain pipe 5 overflows can be reduced.
