Description

Technical Field

[0001] The utility model relates to the technical field of wall waterproof detection, in particular to a construction wall waterproof detection device for engineering. Background Art

[0002] After the decoration of the building's wall is completed, the project supervisor needs to inspect the waterproof performance of the wall. At present, the project supervisor generally uses a spray bottle to spray water on the wall. After the water is sprayed on the wall, observe whether the water droplets are absorbed and diffused by the wall. If more water is absorbed and diffused, it means that the waterproof performance of the wall is poor. On the contrary, if the water droplets hang on the wall, and the water droplets diffuse and are less absorbed, it proves that the waterproof performance of the wall is good.

[0003] The Chinese utility model patent with announcement number CN220120660U discloses a waterproof detection device for building walls for engineering purposes, including a shell, and a universal wheel is installed at the bottom of the shell, and the setting of the universal wheel facilitates the movement of the shell. A water storage tank is installed on the top of the shell, and a spray assembly, a receiving assembly and a measuring assembly are fixedly connected to one side of the shell. The spray assembly is used to spray water onto the wall to be tested, the receiving assembly is used to receive the water sprayed by the spray assembly, and the measuring assembly is used to collect and intuitively display the water received by the receiving assembly. The water collected by the measuring assembly is used to judge the waterproof performance of the wall, which reduces the error of judging the waterproof performance of the wall based on experience. This application has the effect of improving the accuracy of measuring the waterproof performance of the wall.

[0004] However, the above patent still has the following shortcomings during actual use: First, the water-absorbing sponge of the patent moves upward along the wall to be inspected to absorb the sprayed moisture. Since the water-absorbing sponge is in a long strip shape, the water-absorbing sponge is greatly worn by friction with the wall for a long time, and the water-absorbing sponge needs to be replaced frequently, increasing maintenance costs; Second, the water-absorbing sponge of the patent needs to be moved to correspond to the abutment plate before the pressure plate can squeeze water out of the water-absorbing sponge. Once the water-absorbing sponge cannot absorb the sprayed moisture in a single time, the water-absorbing sponge needs to be moved multiple times to correspond to the abutment plate, affecting the detection efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a construction wall waterproof detection device for engineering purposes, so as to solve the problems proposed in the above-mentioned background technology that the water-absorbing sponge is subject to large wear and tear due to friction with the wall for a long time, and the water-absorbing sponge needs to be replaced frequently, which increases the maintenance cost; and the water-absorbing sponge cannot absorb all the sprayed water in a single time, so the water-absorbing sponge needs to be moved multiple times to correspond to the abutment plate, which affects the detection efficiency.
