[0044] On the basis of the above structure, the filter assembly 9 includes a return pipe 91, a filter pipe 92, a filter screen 93, a sewage pipe 94 and a cover 95. The return pipe 91 is embedded and fixed at the bottom of the outer cover 81. The return pipe 91 is connected to the return chamber 82. The filter pipe 92 is threadedly sleeved on the outer side of the bottom of the return pipe 91. The middle inner wall of the filter pipe 92 is fixedly connected with an inclined filter screen 93.

[0047] In this embodiment, by manually rotating the threaded rod 16, the third movable block 17, the guide rod 18 and the second movable block 15 can be controlled to rise vertically synchronously, and at this time, the scissor-type telescopic rods 64 provided on the right sides of the two vertical plates 5 can be controlled to operate synchronously.

[0048] The present invention also provides a construction engineering wall waterproof acceptance detection device and a method of using the same, the steps of which include:

[0049] Step 1: Connect the external water supply pipe and sewage pipe to the high-pressure nozzle 83 and the filter tube 92 respectively, and then manually rotate the threaded rod 16 according to the specific wall point to be sampled, and control the second movable block 15 and the third movable block 17 to rise synchronously through the guide rod 18, and then push the rear fixed plate 7 and the front fixed plate 10 to move synchronously through the two scissor-type telescopic rods 64 until they reach the designated detection position;

[0050] Step 2: Start the servo motor 3 to control the screw rod 4 to rotate, so that the movable tube 2 uses the protruding structure of its outer wall to drive the rear vertical plate 5, the connecting rod assembly 6, the rear fixed plate 7, the spray assembly 8 and the filter assembly 9 to move forward synchronously until the first rubber ring 84 and the second rubber ring 13 are tightly pressed and fitted with the inner and outer walls of the wall respectively;

[0051] Step 3: Turn on the external water pump, supply clean water to the high-pressure nozzle 83 through the existing hose, and continuously spray it toward the wall with pressurized water through the high-pressure nozzle 83 to simulate heavy rain weather. On the other side of the wall, the humidity sensor 12 detects the water seepage of the wall, so as to obtain the waterproof performance data of the wall, and determine whether the wall waterproof acceptance is qualified based on the actual data.

[0052] The working principle of the present invention is as follows:

[0053] When in use, firstly, the hose connected to the water supply source is fixedly connected to the water inlet end of the high-pressure nozzle 83, and the hose for recycling water is fixedly connected to the water outlet end at the bottom of the filter tube 92, and then the device is installed and placed through the door and window openings reserved in the building wall. Figure 8The state shown in the figure is shown in the figure, and the servo motor 3 is started to control the screw rod 4 to rotate. Since the outer walls on both sides of the movable tube 2 are provided with protruding structures, and the inner walls on both sides of the handle 1 are provided with groove structures, the screw rod 4 can control the movable tube 2 to stably extend and slide inside the handle 1 when the screw rod 4 rotates, and the movable tube 2 can drive the rear vertical plate 5, the connecting rod assembly 6, the rear fixed plate 7, the spray assembly 8 and the filter assembly 9 to move forward stably along the guide rod 18 synchronously, so that the first rubber ring 84 and the second rubber ring 13 are respectively tightly pressed and fitted with the inner and outer walls of the wall, which can reduce the interference of external factors on the detection process, enhance the reliability and accuracy of the detection results, and also facilitate the device to be applicable to building walls of different thicknesses for waterproof performance acceptance monitoring;

[0054] The external water source is supplied to the high-pressure nozzle 83 through the existing water pump and hose, and the water is continuously sprayed toward the wall to be tested after being pressurized by the high-pressure nozzle 83 to simulate rainstorm weather. On the other side of the wall, the water seepage of the wall can be detected by the humidity sensor 12, so that the waterproof performance data of the wall can be obtained. During the detection process, the funnel-shaped water return chamber 82 is used to facilitate the water sprayed on the wall to flow back to the water return pipe 91, and the water can be recycled through the filter pipe 92, which is convenient for the reuse of water, so as to save resources and be more environmentally friendly. In the process of water recycling, the impurities such as fine stones on the wall mixed in the water can be filtered and purified through the filter screen 93, and the cover 95 can be unscrewed after the device is used, and the impurities can be discharged and cleaned in time through the sewage pipe 94 to avoid blockage and affect the return water.

[0055] At the same time, the device is also provided with a threaded rod 16. By manually rotating the threaded rod 16, the third movable block 17 can be controlled to drive the second movable block 15 to move vertically upward synchronously through the guide rod 18. At this time, the scissor-type telescopic rods 64 provided on the right sides of the two vertical plates 5 can be used to control the rear fixed plate 7 and the front fixed plate 10 to move horizontally in the same direction synchronously, so as to facilitate the flexible adjustment of the waterproof detection position of the wall, so as to achieve the purpose of multi-point detection. The measured data on the waterproof performance of the building wall is more reliable, and the device is relatively small in size, easy to carry, and more flexible to use.

[0056] It should be noted that the circuit control principle involved in this device and the humidity sensor 12 and controller 11 all adopt mature existing technical means and products, which are not the protection scope emphasized in this case. They are direct citations of existing technologies and will not be described in detail.

[0057] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
