Technical Field

The application relates to the technical field of building drainage, in particular to a building drainage structure.

Background

The drainage structure refers to a general body formed by combining facilities such as collection, transportation, water quality treatment, drainage and the like of drainage in a certain mode; the building drainage structure is an important structure in the building, and can drain rainwater on a roof rapidly in rainy season to prevent house water seepage.

Along with the increase of urban water consumption, water resource consumption is more and more, in order to save energy, the current header tank that is provided with and is linked together with the drain pipe is concentrated the surplus rainwater and is collected in the header tank to with rainwater conversion usable water resource.

Because the rainwater contains a large amount of impurities, the rainwater is filtered in the prior art, a filter screen is usually arranged in a drain pipe to remove larger solid impurities, and then disinfection, sterilization and other working procedures are carried out by adding disinfectant into the water collecting tank in time manually, so that the rainwater is purified to a certain extent, the purified rainwater can be used as domestic water, and energy is saved. However, since rainfall occurs more in summer and the number of rainfall in summer is also large, the frequency of disinfectant addition increases with the increase of the number of rainfall, and at this time, the manual disinfection is troublesome, so that further improvement is required.

Through adopting above-mentioned technical scheme, when rainfall is great, the circulation of drain pipe internal water is more this moment, it is also great to pressing the pressure of briquetting, it is probably appearing when the rainwater in the header tank and communicating pipe intercommunication back this moment, the rainwater just reduces pressing the pressure of briquetting, the liquid outlet just closes this moment, but, this period, along with the rainwater in the header tank increases, and after the liquid outlet that sets up on the rainwater is higher than the kit, it is possible that the rainwater appears entering into the kit through first communication hole, the liquid outlet, mix with the disinfectant, thereby make the disinfectant diluted, with the effect of disinfecting to the rainwater that collects next time. And when diluting the disinfectant, the disinfectant flows into the water collection tank along with water flow, so that the quantity of the disinfectant added into the water collection tank is more, and the frequency of adding the kit into the water collection tank is affected.

Therefore, when the rainwater quantity reaches the level with the lower surface of the first control floating plate below, the first control floating plate gradually floats along with the increase of the rainwater due to the characteristics of the first control floating plate, so that the control rod has a jacking effect, the liquid outlet and the first communication holes are staggered, the possibility that the external rainwater enters the kit through the first communication holes and the liquid outlet and is mixed with the disinfectant is reduced, the possibility that the disinfectant in the kit is diluted is reduced, and the quantity of the disinfectant in the water collecting tank can be controlled.

Preferably, a sealing gasket is arranged on the surface of the first control floating plate close to the control rod.

Through adopting above-mentioned technical scheme, for reducing the possibility that external rainwater enters into the kit through the clearance between first control floating plate and the kit, be close to the surface of control pole at first control floating plate this moment and be provided with sealed the pad to increase the packing to the clearance between first control floating plate and the kit, with the possibility that the rainwater entered into the kit in order to reduce, in order to improve the concentration to the interior disinfectant of kit and keep and reduce the production of unnecessary disinfectant in the header tank.
