Description

Technical Field

[0001] The utility model relates to the field of construction engineering equipment, in particular to a building exterior wall water seepage test device. Background Art

[0002] After the construction of a building, project supervision is required to conduct acceptance inspections on the building. During the acceptance process, multiple performance tests of the building need to be carried out, including the water seepage test of the building wall. Existing water seepage test devices for walls, such as the Chinese utility model patent with the publication number CN209783834U, disclose a device including a water supply component, a spraying component, a bracket for connecting the spraying component, a connecting rod for connecting the bracket to the exterior wall, and a fixing component for fixing the connecting rod. The length direction of the connecting rod is perpendicular to the height direction of the exterior wall. The connecting rod includes an upper rod body and a lower rod body arranged parallel to the upper rod body. The bracket includes a first cross bar and a second cross bar arranged in parallel. The length directions of the first cross bar and the second cross bar are the same as the length direction of the upper rod body. Symmetrically fixed to the side of the first cross bar and the second cross bar away from the exterior wall are a first vertical rod and a second vertical rod. The bracket is driven by a first driving component to move horizontally, and the spraying component is driven by a second driving component to move vertically. When conducting a water seepage test on the exterior wall, it is necessary to test in a certain area. This device sets the nozzle on a planar moving mechanism, and the planar moving mechanism drives the nozzle to move horizontally. After determining a certain area, water is sprayed on the exterior wall area for the water seepage test. Since there is no water blocking structure, the water sprayed on the exterior wall will flow downward along the wall surface, resulting in water loss and reducing the water seepage test effect in the area.

Detailed implementation mode

[0018] The present utility model will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0019] Embodiment: A building exterior wall water seepage testing device includes a test vehicle 1. As shown in the attached Figure 1 drawing, a water spraying assembly 2 is installed on the test vehicle 1. The water spraying assembly mainly includes a water tank arranged on the vehicle body. A water pump is connected to the bottom of the water tank. An inlet pipe is connected to the inlet end of the water tank, and an outlet pipe is connected to the outlet end of the water tank. The liquid outlet end of the water spraying assembly 2 is connected to a nozzle 3, and the nozzle of the outlet pipe is connected to the nozzle; a first cylinder 4 is installed on the platform of the test vehicle 1. The rear end of the first cylinder is connected to a mounting seat, and the first cylinder is installed on the platform of the test vehicle through this mounting seat. The extending end of the first cylinder 4 is connected to a horizontal water baffle 5; first fixing plates 6 are installed on both sides of the platform of the test vehicle 1. An end frame 7 is fixed on the first fixing plate 6. A power component 8 is installed inside the end frame 7. A vertical shaft 9 is rotatably installed in the end frame 7 through a bearing. The output end of the power component 8 is matched with the circumferential part of the vertical shaft 9; a swing frame 10 is arranged on the circumferential part of the vertical shaft 9. A vertical water baffle 11 is installed at the end of the swing frame 10. The horizontal water baffle 5 and the vertical water baffle 11 enclose a test area 12, and the nozzle 3 is arranged in this test area 12. Both the horizontal water baffle 5 and the vertical water baffle 11 have water retaining grooves 21 inside. The edge of the notch of the water retaining groove 21 has a rubber layer. The water retaining groove can temporarily store a certain amount of water, so that the water stays for a longer time, and the rubber layer can have a better blocking effect on the flowing water.

[0020] The power component 8 includes a vertical plate 16 arranged inside the end frame 7. As shown in the attached Figure 2As shown, a second cylinder 17 is installed on one side of the vertical plate 16, and a guiding and limiting slide rail 18 is installed on the other side of the vertical plate 16. A straight rack 19 is slidably installed in the guiding and limiting slide rail 18. The extending end of the second cylinder 17 passes through the guiding and limiting slide rail 18 and is connected to the back side of the straight rack 19. A gear 20 meshing with the straight rack 19 is installed on the circumferential part of the vertical shaft 9. When the second cylinder is started and extends, it drives the straight rack to move in the guiding and limiting slide rail. The straight rack meshes with the gear, causing the gear to rotate and the vertical shaft to rotate accordingly. The vertical water baffle at the end of the swing frame deflects accordingly. The area of the region to be subjected to the water seepage test is different. The deflectable vertical water baffle cooperates with the movable horizontal water baffle to arbitrarily combine into test regions of different areas.

[0021] The swing frame 10 mentioned above includes straight plates 22 arranged on the upper and lower sides of the vertical shaft 9. As shown in the appendix Figure 3 As shown, a limiting rod 23 is installed between the straight plates 22. The ends of the straight plates 22 are provided with second fixing plates 24 connected to the vertical water baffle 11. The swing frame is composed of a plate structure, which has a simple structure, is convenient for disassembly and assembly, and also reduces the weight of the swing frame, making the swing frame more lightweight when rotating. The upper and lower ends of the second fixing plate 24 are connected to the straight plates 22 by screws, which is convenient for the disassembly and installation of the fixing plate. The nozzle 3 is installed on the platform of the test vehicle 1 through a clamping structure. The nozzle adopts a combined structure. A clamping plate is installed on the platform. When installing the nozzle into the clamping plate, part of the nozzle is inserted into the clamping plate, and then the other part of the nozzle is installed. The clamping plate is exactly between the two components.

[0022] The working principle of the present utility model: After determining the exterior wall area to be tested, the first cylinder extends, and the horizontal water baffle comes into contact with the exterior wall. The second cylinder is started, driving the straight rack to move. The straight rack meshes with the gear, causing the vertical shaft and the swing frame to deflect. The vertical water baffle connected to the swing frame deflects and displaces, and the vertical water baffle also comes into contact with the exterior wall. At the same time, the vertical water baffle and the horizontal water baffle enclose a test region, which facilitates the water seepage test within the test region. Secondly, the water baffle can slow down the loss rate of the sprayed water along the building exterior wall, thereby improving the water seepage test effect within the region.
