Description

Technical Field

[0001] The invention belongs to the technical field of wall water seepage detection, and in particular relates to a building exterior wall water seepage detection device. Background Art

[0002] In the field of construction, the waterproof performance of exterior walls is of vital importance. It is directly related to the service life of the building, structural stability and the quality of life of the residents. In actual projects, the problem of water seepage in building exterior walls is extremely common and has become a chronic disease that plagues the construction industry. Water seepage in exterior walls will not only cause water stains, mold, peeling and other conditions on the interior walls, affecting the interior aesthetics and living comfort, but in severe cases it may also cause damage to the wall structure and reduce the overall safety of the building.

[0003] At present, a variety of detection methods have been developed to address the problem of water seepage on building exterior walls, such as the traditional water sprinkling test method, infrared thermal imaging detection method, ultrasonic detection method, etc. Among them, the water sprinkling method is widely used because of its simple structure and low cost. Its working principle is to use a water sprinkling device to continuously and evenly spray water on the exterior wall to simulate a rainfall environment, and observe whether there are signs of water seepage on the indoor wall, so as to judge the waterproof performance of the exterior wall. When the device simulates water sprinkling on the wall, the roller in contact with the water source will produce friction changes due to infiltration, which directly leads to a decrease in the fit stability of the water seepage detection device when it moves on the wall, thereby causing deviations in the wall water seepage detection data. In addition, the existing wall structures are diverse, especially for exterior walls with inclined angles. The contact wheel of the existing device lacks an adaptive adjustment mechanism and cannot achieve dynamic fit according to the inclination of the wall, further exacerbating the detection error.

[0015] 3. The present invention is equipped with an adjustable water seepage component. When the device needs to simulate different water seepage conditions, the first motor drives the perforated tube to rotate at a set speed, and evenly distributed water seepage holes are formed on its surface when it contacts the wall.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, an embodiment of the present invention provides a building exterior wall water seepage detection device, including a lifting component 1, a fixing component 2 is installed on the top of the lifting component 1, and also includes a linkage fitting water seepage mechanism, the linkage fitting water seepage mechanism includes a water seepage component 3, the water seepage component 3 is fixedly installed on the left side of the fixing component 2, the outer edge of the water seepage component 3 is fixedly installed with a fitting component 4, and the top of the fixing component 2 is fixedly connected to a lifting component 5.

The inner sides of the two arc frames 42 are elastically connected with springs 44 on the upper and lower sides. The other side of the two connecting rods 43 is movably hinged with two T-shaped rods 45, and the upper and lower sides of the two T-shaped rods 45 are movably hinged with second hydraulic rods 46. The inner sides of the two T-shaped rods 45 are rotatably installed with a first roller 47 and a second roller 48 from top to bottom; the connecting rod 43 is composed of a rectangular bar and a rotating wheel, and the other ends of the two groups of springs 44 are in contact with the outer edge of the rotating wheel of the connecting rod 43. The fixed ends of the two groups of second hydraulic rods 46 are movably hinged with the inner side of the long strip 41, and the surface roughness of the first roller 47 is greater than that of the second roller 48. The first roller 47 and the second roller 48 can be exchanged within the two T-shaped rods 45.

[0021] When the device moves along the inclined wall, the second hydraulic rod 46 adjusts the expansion angle of the T-shaped rod 45 through the hinge point, so that the first roller 47 or the second roller 48 is selectively pressed according to the wall material, so that the roller always maintains parallel contact with the wall. During adjustment, the connecting rod 43 can slide in the arc frame 42, and the spring 44 is compressed to generate a reverse force, pushing the T-shaped rod 45 to fit the wall. The surface roughness of the first roller 47 is relatively high, which is suitable for drying walls to increase friction. The surface of the second roller 48 is relatively smooth, which can reduce friction resistance after infiltration. By swapping the positions of the two rollers, the movement requirements under different working conditions can be adapted.

[0022] Among them, the lifting assembly 1 includes a base 11, four first hydraulic rods 12 are inserted into the top of the base 11, the telescopic ends of the four first hydraulic rods 12 are fixedly connected to two horizontal bars 13, the tops of the two horizontal bars 13 are fixedly connected to two vertical bars 14, and the two horizontal bars 13 and the two vertical bars 14 together form a well-shaped frame.

[0023] Four first hydraulic rods 12 are vertically installed at the four corners of the base 11. Their telescopic ends are cross-connected by horizontal bars 13 and vertical bars 14 to form a stable cross-shaped frame. When the first hydraulic rods 12 are synchronously extended, the cross-shaped frame drives the fixed components and the water seepage detection mechanism to rise smoothly in the vertical direction to perform an upward water seepage test from bottom to top.

[0024] Among them, the fixed component 2 includes a fixed shell 21, which is fixedly installed on the top of the criss-cross frame. Two water storage tanks 22 are fixedly installed on the right side of the fixed shell 21. A rubber block 23 is fixedly connected between the two water storage tanks 22. The left end of the rubber block 23 is fixedly connected to the inner wall of the fixed shell 21. A collection box 24 is fixedly connected to the left side of the fixed shell 21. A slide 25 is fixedly installed on the left side of the collection box 24. A plurality of inclined grooves 26 are opened on the left inner wall of the collection box 24; the plurality of inclined grooves 26 are equidistantly distributed on the left inner wall of the collection box 24, and the right side of the two long strips 41 is fixedly connected to the left side of the fixed shell 21.

[0025] The collection box 24 contacts the wall through the slide 25 installed on the left side. The inclined groove 26 opened on its inner wall guides the leaking water to be collected in a specific direction during the detection process. When the device moves along the wall, the water in the water storage tank 22 flows through the seepage component 3 and acts on the wall. The excess water that penetrates into the wall is intercepted by the collection box 24 and used to judge the amount of seepage.

[0026] Among them, the water seepage component 3 includes a rectangular block 31, which is fixedly installed on the left side of the fixed shell 21. A plurality of circular holes 32 are opened on the left side of the rectangular block 31, and a perforated tube 33 is rotatably installed in the plurality of circular holes 32. The front end of the perforated tube 33 is fixedly connected to the first motor 34, and a plurality of rectangular grooves 35 are opened at the bottom of the plurality of circular holes 32. A shift bar 36 is movably hinged in the plurality of rectangular grooves 35, and the front side of the shift bar 36 is fixedly connected to the second motor 37; the plurality of circular holes 32 and the plurality of rectangular grooves 35 are equidistantly opened on the left side of the rectangular block 31, and connecting pipes are installed in the perforated tube 33 and the rectangular grooves 35, and the two connecting pipes are fixedly connected to the two water storage tanks 22.

[0027] When the device needs to simulate different water seepage conditions, the first motor 34 drives the perforated tube 33 to rotate at a set speed, and its surface will form evenly distributed water seepage holes when it contacts the wall. At the same time, the second motor 37 drives the dial 36 to swing periodically in the rectangular groove 35, directing the water flow output by the water storage tank 22 to the water seepage holes at different angles. By adjusting the operating parameters of the two groups of motors, the distribution density and water seepage amount of the water seepage holes can be controlled. First, it adapts to the detection needs of walls of different materials, and second, it saves water resources. The sampling form of detection is used to expand the detection range of a single operation.

[0028] Preferably, the lifting assembly 5 includes two universal joints 51, which are fixedly installed on the top of the fixed shell 21. The tops of the two universal joints 51 are fixedly connected to ropes 52. The other ends of the two ropes 52 are wrapped with a rotating shaft 53. The outer edge of the rotating shaft 53 is sleeved with a top shell 54. The rotating shaft 53 is rotatably installed on the right bottom of the top shell 54. A winch 55 is fixedly installed inside the top shell 54. The outer edges of the two ropes 52 are wrapped around the outer edges of the winch 55. The front and rear sides of the top shell 54 are movably hinged with fixing bolts 56.

[0029] The fixing bolt 56 allows for flexible installation of the hoisting assembly 5. When the device needs to be hoisted on an inclined wall for testing, the winch 55 adjusts the hanging position of the fixed shell 21 by tightening or loosening the rope 52. The universal joint 51 allows the rope 52 to deflect freely in the vertical space, so that the water seepage assembly 3 maintains vertical contact with the wall. The rotating shaft 53 cooperates with the top shell 54 to achieve uniform winding of the rope 52, avoiding single-point stress concentration.

[0030] Working principle: When using the present invention, the equipment can be tested for water seepage from bottom to top through the lifting component 1, or the equipment can be tested for water seepage from top to bottom by hoisting through the hoisting component 5, so as to adapt to different test environments and different detection areas. The four first hydraulic rods 12 are vertically installed at the four corners of the base 11, and their telescopic ends are cross-connected by the horizontal bars 13 and the vertical bars 14 to form a stable well-shaped frame. When the first hydraulic rods 12 are synchronously extended, the well-shaped frame drives the fixing component and the water seepage detection mechanism to be lifted smoothly in the vertical direction to perform an ascending water seepage test from bottom to top.

[0031] The fixing bolt 56 allows for flexible installation of the hoisting assembly 5. When the device needs to be hoisted on an inclined wall for testing, the winch 55 adjusts the hanging position of the fixed shell 21 by tightening or loosening the rope 52. The universal joint 51 allows the rope 52 to deflect freely in the vertical space, so that the water seepage assembly 3 maintains vertical contact with the wall. The rotating shaft 53 cooperates with the top shell 54 to achieve uniform winding of the rope 52, avoiding single-point stress concentration.

[0032] When the device moves along the inclined wall, the second hydraulic rod 46 adjusts the expansion angle of the T-shaped rod 45 through the hinge point, so that the first roller 47 or the second roller 48 is selectively pressed according to the wall material, so that the roller always maintains parallel contact with the wall. During adjustment, the connecting rod 43 can slide in the arc frame 42, and the spring 44 is compressed to generate a reverse force, pushing the T-shaped rod 45 to fit the wall. The surface roughness of the first roller 47 is relatively high, which is suitable for drying walls to increase friction. The surface of the second roller 48 is relatively smooth, which can reduce friction resistance after infiltration. By swapping the positions of the two rollers, the movement requirements under different working conditions can be adapted.

[0033] When the device needs to simulate different water seepage conditions, the first motor 34 drives the perforated tube 33 to rotate at a set speed, and its surface will form evenly distributed water seepage holes when it contacts the wall. At the same time, the second motor 37 drives the dial 36 to swing periodically in the rectangular groove 35, directing the water flow output by the water storage tank 22 to the water seepage holes at different angles. By adjusting the operating parameters of the two groups of motors, the distribution density and water seepage amount of the water seepage holes can be controlled. First, it adapts to the detection needs of walls of different materials, and second, it saves water resources. The sampling form of detection is used to expand the detection range of a single operation.

[0034] The collection box 24 contacts the wall through the slide 25 installed on the left side. The inclined groove 26 opened on its inner wall guides the leaking water to be collected in a specific direction during the detection process. When the device moves along the wall, the water in the water storage tank 22 flows through the seepage component 3 and acts on the wall. The excess water that penetrates into the wall is intercepted by the collection box 24 and used to judge the amount of seepage.
