Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, so as to further understand the concept, the technical problems solved, the technical features constituting the technical solutions, and the technical effects brought by the technical solutions.

As shown in fig. 1-2, a basement water-proof and drainage structure in a water-rich area comprises a basement base surface 1, a drainage groove 2 with a slope is cut on the basement base surface 1, a drainage filter plate 3 is embedded above the drainage groove 2, a floating ball hydraulic control switch 4 is fixedly installed on the top surface of one end of the bottom of the drainage filter plate 3 close to the low point of the drainage groove 2, a drainage port 8 is arranged on the side wall of the low point of the drainage groove 2 and is communicated with a dark drainage pipe 9 through the drainage port 8, and a check disc 12 for blocking the drainage port 8 is hinged to the top of the joint of the drainage port 8 and the dark drainage pipe 9 where the dark drainage pipe 9 is communicated with an underground rainwater pipe 11; the device also comprises a water pumping pipe 5 extending into the bottom of the low point of the drainage channel 2, wherein the water pumping pipe 5 is communicated with an underground rainwater pipe 11 through a water pumping pump 6, and the water pumping pump 6 is electrically connected with a floating ball hydraulic control switch 4; the well lid 10 is installed to the input of secret downspout 11 is inlayed.

In the use of the utility model, the accumulated water on the basement base surface 1 can be concentrated in the drainage groove 2, because the drainage groove 2 has a slope, and the end at the low point is a drainage end, the accumulated water can reach the dark drainage pipe 9 through the drainage port 8 along the drainage groove 2 and finally be directly drained into the underground rainwater pipe 11, and the non-return disc 12 can be flushed up when the accumulated water passes through the drainage port 8, so that the drainage of the accumulated water is not influenced. When the water level in the underground rainwater pipe 11 rises, the water of the underground rainwater pipe 11 flows back to the hidden drainage pipe 9, the water pressure can attach the check disc 12 to the drainage port 8, and the water of the underground rainwater pipe 11 is prevented from flowing back to the drainage groove 2 or the basement base surface 1. When the accumulated water on the basement base surface 1 is too much and the drainage speed of the drainage groove 2 is too low, the water level of the drainage groove 2 rises too much to trigger the floating ball hydraulic control switch 4 to start the water suction pump 6, the accumulated water can be directly discharged into the underground rainwater pipe 11 from the water suction pipe 5, and the drainage overflow of the drainage groove 2 is avoided.

As a preferred embodiment, the pumping pipe 5 communicates with the top of the underground rainwater pipe 11.

In this embodiment, the upper end intercommunication of drinking-water pipe 5 and secret downspout 11 discharges unnecessary ponding from the top to in the secret downspout 11 through the effect of suction pump 6, leads to the water backward flow that suction pump 6 took out when avoiding the inside water yield of secret downspout 11 to be more.

In a preferred embodiment, the area of the check disc 12 is larger than that of the drain opening 8, and a blocking protrusion 13 matched with the size of the drain opening 8 is arranged at the center of the check disc 12.

In the present embodiment, the check disc 12 can cover the whole water discharge opening 8, and the blocking protrusion 13 is inserted into the water discharge opening 8 for blocking, so that the water discharge opening 8 can be completely blocked without leaving a large gap, and the check effect of the check disc 12 on the discharged water in the underground rainwater pipe 11 can be ensured.

As a further embodiment, the disc surface of the non-return disc 12 on the side close to the water outlet 8 is provided with a rubber pad.

In this embodiment, the effect of rubber pad lies in ensuring that the water in the underground rainwater pipe 11 rises to the time of non return dish 12 height on the water, compresses tightly non return dish 12 in the 8 outsides of outlet through the water pressure effect to carry out waterproof sealing through the rubber pad, because the water pressure in the underground rainwater pipe 11 is obviously greater than the water pressure in the water drainage tank 2 this moment, consequently ponding in the water drainage tank 2 is more and more, and arrange to the underground rainwater pipe 11 in through suction pump 6 and drinking-water pipe 5, avoid ponding backward flow in the underground rainwater pipe 11 to the water drainage tank 2 and underground indoor.

As a preferred embodiment, the drainage filter plate 3 is clamped on the basement base surface 1 at two sides of the drainage groove 2 through elastic buckles at the left end and the right end of the lower surface.

In this embodiment, be connected for dismantling between the basement base face 1 of drainage filter plate 3 and drainage groove 2 both sides, the bayonet socket is cut for 2 both sides through the drainage groove on basement base face 1 to concrete connection mode, and the elasticity buckle of going out through drainage filter plate 3 lower surface is impressed drainage filter plate 3 in the bayonet socket to play fixed drainage filter plate 3 and make things convenient for follow-up drainage filter plate 3 of demolising and clean and change floater liquid accuse switch 4's purpose inside drainage groove 2. The elastic buckle is the prior art, and therefore the specific structure thereof is not described herein.

The terms "connected" and "fixed" in the description of the present invention may be fixed, formed, welded, or mechanically connected, and the specific meaning of the above terms in the present invention is understood.
