specific Embodiment approach 1

[0023] Specific Embodiment 1: In this embodiment, the building drainage water seal damage real-time detection device, the building drainage system includes sanitary appliances, traps 5, drainage standpipes 6, drainage branch pipes, clearing equipment, lifting equipment, local sewage treatment structures and roof extensions Ventilation pipe 4, the sanitary appliance communicates with the drainage branch pipe through the water trap 5, and the drainage branch pipe communicates with the drainage vertical pipe 6, and the water in the drainage vertical pipe 6 is introduced into the local sewage treatment structure by the lifting equipment, and the drainage vertical pipe 6 The top of the roof is provided with a top-extending air pipe 4, and the peripheral surface of the drain standpipe 6 is provided with clearing equipment; the real-time detection device includes an intelligent pressure transient analysis management software system 1 and a pressure transient detection and identificatio...

specific Embodiment approach 2

[0025] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the water hammer monitoring pressure sensor 3 is connected with the intelligent pressure transient analysis management software system 1 through the GPRS remote transmission communication function.

[0026] Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0027] Specific embodiment three: the method of using the real-time detection device for building drainage water seal damage in this embodiment is completed according to the following steps:

[0028] Step 1: Find the length of each pipe in the construction drawing of the drainage system of the building to be tested and the distance between each trap 5 and the drainage standpipe 6, and measure the pressure transient signal generator 2 and the water hammer monitoring pressure sensor 3 in the drainage distance on riser 6;

[0029] Step 2: Utilize the length of each pipeline in step 1, the distance between each trap 5 and the drainage riser 6, and the distance between the pressure transient signal generator 2 and the water hammer monitoring pressure sensor 3 on the drainage riser 6, and Combined with the construction drawing of the drainage system of the building to be tested, an equal-scale hydraulic model of the drainage system to be tested is constructed in the intelligent pres...

Abstract

The invention discloses a real-time detection device for building drainage water seal damage and a method for using the same, and relates to the technical field of building drainage water seal detection and analysis. The purpose of the present invention is to solve the problem that the existing building drainage system requires manpower to enter the room and rely on manual on-site visual inspection or sniffing to complete the water seal inspection, and it is difficult to find out the failure of the water seal in time. Method: By extracting the high scan rate data and recording the pressure fluctuation curve Xn+1 in the functional module and the pressure fluctuation curve X in the database 0 ~Xn are compared respectively, in the pressure fluctuation curve X 0 From ~Xn, find the pressure fluctuation curve that is most consistent with the pressure fluctuation curve Xn+1 pressure fluctuation trend. The corresponding simulated working condition is the actual situation of the water seal of the drainage system of the building to be tested, and the water seal is intact or the specific water seal failure position is obtained. conclusion. The invention can obtain a building drainage water seal damage real-time detection device and a using method thereof.

Description

technical field [0001] The invention relates to the technical field of detection and analysis of building drainage water seals, in particular to a real-time detection device for building drainage water seal damage and a method for using the same. Background technique [0002] The main function of the building's drainage system is to quickly remove the discharge of appliances, and at the same time ensure that the dirty gas in the sewage pipe network will not enter the indoor space and pollute the environment. The main protection is the water seal in the trap. Water seal is a measure to use a certain height of hydrostatic pressure to resist the change of air pressure in the drain pipe and prevent gas and small insects in the drain pipe from entering the room. There are no disinfection measures for the drainage system in the building in the urban water system circulation, so the water seal of the drainage system becomes the only line of defense to isolate the virus inside the ...
