Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-8 , an embodiment provided by the present invention:

[0026] A flat-roof water seepage detection device for residential buildings, including a heightening block 1, a negative pressure chamber 10, and a rotating main shaft 13. A liquid tank 2 is arranged on the top of the heightening block 1 to increase the gravitational potential energy of the liquid tank 2 and the liquid inside the liquid tank 2. The liquid The inside of the box 2 is pr...

Abstract

The invention discloses a residential building flat water seepage detection device. The device comprises a heightening block, a negative pressure cabin, and a rotating main shaft; a liquid tank is arranged at a top end of the heightening block, and a pressure plate is arranged in the liquid tank, and a pressure weight block is fixedly arranged at the top end of the pressure plate; an airbag is arranged at the top end of the pressure weight block, connecting air pipes are arranged at two sides of the airbag, a sealing rubber sleeve is arranged at a bottom end of the balance weight plate, one-way valves are embedded at two sides of the negative pressure cabin, a sealing ring is arranged at the bottom of the negative pressure cabin, a sealing plate is sleeved on an outer wall of the rotatingmain shaft, and first exhaust fan blades are uniformly arranged at the outer wall of the rotating main shaft. Whether the inclined cracks are existent adjacent to a detection point can be effectivelydetected, a detection item is broadened, the detection project is broadened, the detection result is more intuitive, the use is more convenient, and detection device can make accurate judgment.

Description

technical field [0001] The invention relates to the field of water seepage detection devices, in particular to a water seepage detection device for flat roofs of residential buildings. Background technique [0002] Due to the poor construction technology of residential buildings and the poor building materials used, the flat roof of residential buildings is prone to leakage, and oblique cracks are prone to appear inside the flat roof. However, the existing smog method for water seepage detection cannot detect oblique cracks. The oblique cracks with internal water accumulation will also affect the detection results when using infrared thermal imaging detection devices. The water seepage detection is not comprehensive enough. At the same time, the commonly used roofing The leak detection device has a long detection time and high detection cost, and is not suitable for leak detection of flat roofs of residential buildings. Contents of the invention [0003] The object of the...
