A safe and intelligent drainage system and drainage method

Abstract

A system for safe intelligent drainage comprises a draining main pipe, a first water falling port, a second water falling port, ..., an Nth water falling port, a first confluence point, a second confluence point, ..., and an N confluence point. The first water falling port, the second water falling port, ..., and the Nth water falling port are connected with the first confluence point, the second confluence point, ..., and the N confluence point respectively through a first drainage branch pipe, a second drainage branch pipe, ..., and an Nth drainage branch pipe, and accumulated water is sequentially drained into the draining main pipe through the water falling ports, the drainage branch pipes and the confluence points. The head end of the first drainage branch pipe is provided with a valve, head ends and tail ends of the remaining drainage branch pipes are provided with valves, the tail ends of the draining main pipe between the confluence point in the water flow direction are respectively provided with valves, and the valves are in an open state and a closed state. According to the system for safe intelligent drainage and a drainage method, water is leaked in shortest time, roofing safe drainage is not influenced, and water leakage points are selectively maintained in time.

Description

technical field [0001] The invention relates to the field of roof drainage, in particular to a safe and intelligent drainage system and a drainage method. Background technique [0002] In the roof rainwater drainage system used in the prior art, the drainage pipes are made of plastic materials. Due to the thermal expansion and contraction of the pipes and the excessive vacuum negative pressure formed in some pipes due to improper design, the problem of being sucked flat may occur, and as the pipes Aging, there are other hidden dangers such as water leakage and breakage at the pipe connection. Once the pipe leaks, it is impossible to repair the pipe immediately, and at the same time, it cannot effectively solve the water leakage completely to ensure the safety of the entire roof drainage. [0003] In the prior art, the general procedures for emergency repair after water leakage occurred are: the customer calls for repair-manufacturer's response-temporary solution to the probl...

AI Technical Summary

Problems solved by technology

[0004] The problems existing in the prior art are: a. There is a time interval between the repair report and the emergency repair; b. Measures such as temporary blocking and bandaging of the water outlet and the water leak can only reduce a certain amount of water leakage, but cannot completely solve the water leakage problem; Due to height difference and slippery conditions, when it rains, emergency repair personnel go up and down the roof and there are potential personal safety hazards during emergency repair construction; d. The time interval between repair reporting and emergency repair causes a large amount of water in the customer's room, causing losses; e. During the time of blocking the drain, During the emergency repair of the water leak, the drainage system cannot drain normally, resulting in an increase in the amount of water on the roof, and there is a risk of flooding; f. Due to the leaky gap or the water outlet is not tightly sealed, there is water inside and outside the pipe, and electric melting and hot melting cannot be performed To connect the pipes, only temporary measures can be taken, and the water leakage cannot be completely eliminated
