Description

Technical Field

[0001] This invention relates to the field of water seepage detection technology, and more specifically, to a device for detecting water seepage in building walls. Background Technology

[0002] Water seepage in building walls is a common quality hazard in construction projects. It not only affects the building's appearance but can also lead to decreased structural strength, damp damage to interior decorations, and even mold growth, seriously impacting the building's safety and durability. Therefore, accurate and efficient detection of wall seepage after construction or during use is crucial. Currently, the mainstream methods for detecting wall seepage in the industry are mainly divided into two categories: manual water spraying and sensor-based detection. Manual water spraying requires inspectors to spray water onto the wall surface using tools such as hoses and watering cans, and then visually inspect for dampness or leakage. This method is cumbersome, labor-intensive, and heavily influenced by the inspector's subjective judgment, resulting in low detection efficiency, large errors, and difficulty in covering high or large areas of the wall. In contrast, sensor observation method has gradually become the mainstream choice for wall seepage detection due to its advantages of convenient detection, high efficiency and accurate results. Its core is to use infrared probes and moisture meters to objectively collect and analyze the moisture content and leakage of the wall, effectively avoiding the subjectivity and limitations of manual detection.

[0003] However, existing sensor-based detection methods still have significant technical shortcomings in practical applications, hindering their detection effectiveness and widespread application. On the one hand, these methods require a transport device to move the infrared probe and moisture meter across the wall surface for full-area detection. However, existing transport devices often employ a track and robot structure, requiring precise installation and fixation of the track before detection, resulting in complex and time-consuming procedures. Furthermore, the combined track and robot design is cumbersome, with numerous components, significantly increasing manufacturing and maintenance costs. On the other hand, existing transport devices lack stability during movement. Vibration and swaying of the device itself are directly transmitted to the infrared probe and moisture meter, causing data deviations and affecting the accuracy of seepage detection. This is especially problematic when detecting minute leaks, where such swaying errors can lead to missed or false detections. In addition, some transport devices lack mobility, making them unsuitable for detecting walls of different heights and structural types, further limiting their applicability. Therefore, developing a simple, low-cost, stable, and highly accurate building wall seepage detection device has become a pressing technical challenge for the industry.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] In view of the problems in related technologies, the present invention proposes a building wall seepage detection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this invention is implemented as follows:

[0007] A building wall seepage detection device includes: a motion device, a moisture meter, and a suspension cable. The suspension cable is used to install on the wall to be tested, and the moisture meter is installed at the bottom of the motion device. Both the motion device and the moisture meter are connected to the suspension cable for transmission.

[0008] The motion device includes a protective shell, an assembly shell is snapped into the inner wall of the protective shell, the sling slides through the protective shell and the assembly shell, an auxiliary displacement component is assembled at the bottom of the assembly shell, and a drive component is assembled at the top of the assembly shell.

[0009] A bracket is fixedly installed on the outer wall of the protective shell. A servo motor is fixedly installed on the top of the bracket. A swing arm is fixedly installed on the output end of the servo motor. A second servo motor is fixedly installed on the top of the swing arm. An infrared sensor is fixedly installed on the output end of the second servo motor.

[0010] Furthermore, the auxiliary displacement component includes: a bridge-shaped frame, which is fixedly connected to the inner wall of the middle part of the assembly shell; a strip box is fixedly installed on the bottom inner wall of the bridge-shaped frame; a powder-passing groove is opened on the inner wall of the strip box; the left end of the powder-passing groove passes through the bottom of the strip box; a cable-passing cylinder is fixedly installed on the top left end of the strip box; and an anti-slip powder box is fixedly installed on the top right end of the strip box. Both the anti-slip powder box and the cable-passing cylinder are connected to the powder-passing groove, and the sling slides through the bridge-shaped frame and the cable-passing cylinder.

[0011] Furthermore, a transmission roller is rotatably connected to both sides of the bottom of the assembly shell, and the sling is engaged with the two sets of transmission rollers. A gear is fixedly installed on the end wall of the transmission roller located on the outside of the assembly shell, and the two sets of gears mesh.

[0012] Furthermore, the driving component includes a base plate, which is fixedly connected to the inner wall of the top of the assembly shell. A sliding groove is provided on the base plate, and an inner sliding track is provided on the inner wall of the top of the assembly shell. Sliding blocks are slidably connected to both sides of the sliding groove, and the two sets of sliding blocks are symmetrically arranged. A limiting frame is fixedly installed on the top of the sliding block, and the top of the limiting frame is slidably connected to the inner sliding track on the top of the assembly shell. A transmission roller is rotatably connected to the inner wall of the limiting frame.

[0013] The top of the bridge frame is rotatably connected to a rotating plate, and both ends of the rotating plate are rotatably connected to push columns. The end walls of the two sets of push columns are rotatably connected to the side walls of the corresponding slide blocks. A motor is fixedly installed on the inner wall of the top of the bridge frame, and the output end of the motor is fixedly connected to the middle of the rotating plate.

[0014] Furthermore, a rotating shaft is rotatably connected to the inner wall of the assembly shell, and a slot is formed on the rotating shaft. Helical gears are slidably connected to both sides of the slot. A locking block is provided on the inner wall of the middle part of the helical gears, and the locking block engages with the slot. Helical gears are fixedly installed on the front wall of the transmission rollers. Helical gears mesh with helical gears on the corresponding side. Helical gears are rotatably connected to the end wall of the slide block on the corresponding side.

[0015] Motor 2 is fixedly installed on the outer wall of the assembly shell, and the output end of motor 2 is fixedly connected to the end wall of the rotating shaft. Helical gear 3 is rotatably connected to the inner wall of the assembly shell. Helical gear 4 is fixedly installed on the right end wall of the rotating shaft, and helical gear 4 meshes with helical gear 3. Belt conveyor 1 is installed on the end wall of helical gear 3 located outside the assembly shell. Belt conveyor 2 is installed on the bottom outer wall of belt conveyor 1, and the output end of belt conveyor 2 is fixedly connected to the outer gear.

[0016] Furthermore, a pulley is rotatably connected to the top of the protective shell, and a pulley is rotatably connected to the bottom of the moisture meter, and both pulleys are used to contact the wall.

[0017] Furthermore, the moisture meter is fixedly connected to the bottom of the assembly housing, and the sling passes through the moisture meter.

[0018] Furthermore, the powder passage is used to fill anti-slip powder, and the anti-slip powder can fall onto the sling through the powder passage.

[0019] Furthermore, the first servo motor is used to drive the swing arm to rotate the second servo motor, and the second servo motor is used to drive the infrared sensor to rotate.

[0020] Furthermore, the moisture meter detects moisture based on the absorption characteristics of infrared light of a specific wavelength, which is used to make a preliminary judgment on whether the wall is leaking, and the infrared probe is used to conduct detailed detection of the leaking area.

[0021] The beneficial effects of this invention are:

[0022] This invention replaces the complex form of existing tracks and handling robots by setting up a combination structure of slings and motion devices. Before testing, only the two ends of the sling need to be fixed to the top and bottom of the wall respectively to carry out the testing operation. No additional track installation and debugging are required, which greatly simplifies the testing preparation process. At the same time, the overall structure of the device is simplified and the parts are rationally arranged, which effectively reduces the manufacturing and maintenance costs of the equipment. Meanwhile, with the cooperation of the anti-slip powder box and powder passage in the auxiliary displacement component, when the motion device moves along the sling, the anti-slip powder is automatically dropped onto the surface of the sling by the natural vibration of the sling. This significantly increases the friction between the transmission roller and the sling. With the motor one driving the rotating plate and the push column in the drive component to drive the slide and limit frame to move, the transmission roller two can accurately clamp the sling. This can quickly stabilize the device when the moisture meter detects water seepage, avoiding the interference of the motion device shaking to the sensor. Combined with the multi-angle adjustment function of the infrared probe by the servo motor one and servo motor two, the accuracy of water seepage area detection is ensured, which effectively solves the problem of insufficient detection accuracy caused by shaking in existing devices.

[0023] Furthermore, this invention drives the rotating shaft to rotate via motor two, which in turn drives the helical gear set and belt conveyor to rotate the transmission roller one and transmission roller two synchronously. This enables the moving device to move smoothly and efficiently along the suspension cable. Combined with the real-time monitoring of the moisture meter and the precise detection of the infrared probe, an integrated detection process of full-area scanning, leakage location and detailed detection is formed, which greatly improves the detection efficiency. At the same time, the setting of pulley one and pulley two not only helps the device to maintain stable movement, but also can adapt to different wall surface structures, which broadens the applicability of the device. Overall, it meets the core requirements of low cost, high precision and high efficiency in the detection of water seepage in building walls. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0042] According to an embodiment of the present invention, a device for detecting water seepage in building walls is provided.

[0043] like Figures 1-13 As shown, the building wall seepage detection device according to an embodiment of the present invention includes a motion device 100, a moisture meter 200 and a suspension cable 300. The suspension cable 300 is installed on the wall to be tested, and the moisture meter 200 is installed at the bottom of the motion device 100 and is connected to the suspension cable 300 in a transmission manner. The motion device 100 includes a protective shell 110, and an assembly shell 120 is snapped into the inner wall of the protective shell 110. The suspension cable 300 slides through the protective shell 110 and the assembly shell 120. An auxiliary displacement component 130 is assembled at the bottom of the assembly shell 120, and a drive component 150 is assembled at the top of the assembly shell 120.

[0044] Moisture meter 200 is fixedly connected to the bottom of assembly shell 120, and sling 300 passes through moisture meter 200. A bracket 190 is fixedly installed on the outer wall of protective shell 110. A servo motor 191 is fixedly installed on the top of bracket 190. A swing arm 192 is fixedly installed at the output end of servo motor 191. A servo motor 193 is fixedly installed at the top of swing arm 192. An infrared probe 194 is fixedly installed at the output end of servo motor 193. In this invention, servo motor 191 is driven to rotate servo motor 193 at the top of swing arm 192, and servo motor 193 is driven to rotate infrared probe 194, thereby enabling detailed detection of water seepage in the area.

[0045] Specifically, such as Figure 6 , Figures 8 to 10 As shown, the auxiliary displacement assembly 130 includes a bridge frame 131, which is fixedly connected to the inner wall of the middle part of the assembly shell 120. The assembly shell 120 supports the bridge frame 131. A strip box 132 is fixedly installed on the inner wall of the bottom of the bridge frame 131. A powder channel 133 is opened on the inner wall of the strip box 132. The left end of the powder channel 133 passes through the bottom of the strip box 132. The powder channel 133 is always filled with anti-slip powder. When the sling 300 causes the strip box 132 to vibrate, the anti-slip powder in the powder channel 133 can fall onto the sling 300. The top of the left end of the strip box 132 is fixed. A cable guide 134 is installed to limit the movement of the sling 300. An anti-slip powder box 135 is fixedly installed on the top right end of the strip box 132. Both the anti-slip powder box 135 and the cable guide 134 are connected to the powder channel 133. The sling 300 slides through the bridge frame 131 and the cable guide 134. In this invention, when the motion device 100 moves, the sling 300 will vibrate. At this time, the anti-slip powder inside the anti-slip powder box 135 will fall onto the sling 300 through the left end of the powder channel 133, increasing the friction between the transmission roller 140 and the sling 300.

[0046] At the same time, such as Figure 7 As shown, both sides of the bottom of the assembly shell 120 are rotatably connected to transmission rollers 140. The sling 300 is in transmission cooperation with the two sets of transmission rollers 140. Gears 141 are fixedly installed on the end wall of the transmission rollers 140 located on the outside of the assembly shell 120, and the two sets of gears 141 mesh.

[0047] In addition, such as Figure 6 , Figures 11 to 13As shown, the drive assembly 150 includes a base plate 151, which is fixedly connected to the inner wall of the top of the assembly shell 120. The assembly shell 120 provides support for the base plate 151. A groove 152 is formed on the base plate 151, and an inner slide rail 121 is formed on the inner wall of the top of the assembly shell 120. Slide seats 153 are slidably connected to both sides of the groove 152, and the two sets of slide seats 153 are symmetrically arranged. A limit frame 154 is fixedly installed on the top of the slide seat 153. The top of the limit frame 154 is slidably connected to the inner slide rail 121 on the top of the assembly shell 120, which can limit and guide the movement of the limit frame 154. A second transmission roller 155 is rotatably connected to the inner wall of the limit frame 154. The sling 300 can drive and cooperate with the two sets of second transmission rollers 155. The second transmission roller 155 can follow the movement of the limit frame 154, so that the two sets of second transmission rollers 155 can move together. 155 can clamp the sling 300. The top of the bridge frame 131 is rotatably connected to the rotating plate 136. Both ends of the rotating plate 136 are rotatably connected to the push column 137. The end walls of the two sets of push columns 137 are rotatably connected to the side walls of the corresponding slides 153. The top inner wall of the bridge frame 131 is fixedly installed with the motor 138, and the output end of the motor 138 is fixedly connected to the middle of the rotating plate 136. In this invention, when the moisture meter 200 detects water seepage inside the wall, the motor 138 drives the rotating plate 136 to rotate. The two sets of push columns 137 can pull the two sets of slides 153 and the limiting frame 154 to move inward, thereby driving the two sets of transmission rollers 155 to move inward, clamping the sling 300. At the same time, the drive motor 163 is stopped, so that the assembly shell 120 stays on the sling 300.

[0048] In addition, such as Figure 6 and Figure 11As shown, a rotating shaft 160 is rotatably connected to the inner wall of the assembly housing 120, providing support for the rotating shaft 160. A slot 161 is formed on the rotating shaft 160, and helical gears 162 are slidably connected to both sides of the slot 161. The helical gears 162 rotate with the rotating shaft 160. A locking block is provided on the inner wall of the middle of the helical gears 162, and the locking block can engage with the slot 161, allowing the helical gears 162 to move laterally on the rotating shaft 160. However, when the rotating shaft 160 rotates, the helical gears 162 can rotate with the rotating shaft 160. A helical gear 156 is fixedly installed on the front wall of the second transmission roller 155. The helical gear 156 meshes with the corresponding helical gear 162. When the rotating shaft 160 rotates, the helical gear 156 and the helical gear 162 drive the second transmission roller 155 to rotate. The helical gear 162 is rotatably connected to the end wall of the corresponding slide block 153. A motor 163 is fixedly installed on the outer wall of the assembly shell 120, and the output end of the motor 163 is fixedly connected to the end wall of the rotating shaft 160. A helical gear 170 is rotatably connected to the inner wall of the assembly shell 120. A helical gear 164 is fixedly installed on the right end wall of assembly housing 120, and helical gear 164 meshes with helical gear 170. A belt conveyor 171 is installed on the end wall of helical gear 170 outside the assembly housing 120. A belt conveyor 172 is installed on the bottom outer wall of belt conveyor 171, and the output end of belt conveyor 172 is fixedly connected to the outer gear 141. In this invention, a drive motor 163 drives the rotating shaft 160 to rotate, thereby causing helical gear 164 to mesh with helical gear 170, and the belt conveyor... The transmission action of device 171 and conveyor 172 can drive two sets of gears 141 to mesh, thereby driving two sets of transmission rollers 140 to rotate, assisting the assembly shell 120 to move. At the same time, the rotation of the rotating shaft 160 can also drive two sets of helical gears 162 and helical gear 156 to mesh, thereby driving two sets of transmission rollers 155 to rotate. In conjunction with the rotation of transmission rollers 140, the assembly shell 120 can slide on the steel cable, thereby driving the moisture meter 200 and infrared probe 194 to move on the wall.

[0049] This technical solution, such as Figure 1 As shown, a pulley 180 is rotatably connected to the top of the protective shell 110, and a pulley 210 is rotatably connected to the bottom of the moisture meter 200. The principle of the moisture meter 200 is that water exhibits strong absorption characteristics for infrared light of certain specific wavelengths. When the material is irradiated with infrared light of these specific wavelengths, the water contained in the material will absorb part of the energy of the infrared light. The more water it contains, the more it absorbs. Therefore, the amount of reduction in reflected light can be measured to calculate the moisture content of the material. Both pulley 210 and pulley 180 are in contact with the wall. In this invention, pulley 180 and pulley 210 can assist the movement of the protective shell 110 and the moisture meter 200.

[0050] Using the above scheme, the specific implementation process is as follows: After installing the motion device 100 and the moisture meter 200 on the sling 300, the sling 300 is installed on the wall to be tested, so that both pulley 180 and pulley 210 are in contact with the wall, and the motion device 100 and the moisture meter 200 are located at the bottom of the wall. The drive motor 2163 drives the rotating shaft 160 to rotate, thereby driving the helical gear 4164 and helical gear 3170 to mesh. Through the transmission action of belt conveyor 171 and belt conveyor 2172, the two sets of gears 141 can be driven to mesh, thereby driving the two sets of transmission rollers 140 to rotate. The auxiliary assembly shell 120 moves, and at the same time, the rotation of the rotating shaft 160 can also drive the two sets of helical gears 162 and 156 to mesh, thereby driving the two sets of transmission rollers 155 to rotate. In conjunction with the rotation of transmission roller 140, the assembly shell 120 can slide on the steel cable, thereby driving the moisture meter 200 and infrared probe 194 to move on the wall, thereby monitoring the water seepage inside the wall. While the moving device 100 is moving, the suspension cable 300 will vibrate. At this time, the anti-slip powder inside the anti-slip powder box 135 will fall onto the suspension cable 300 through the left end of the powder trough 133, increasing the friction between the transmission roller 140 and the suspension cable 300.

[0051] Meanwhile, when the moisture meter 200 detects water seepage inside the wall, the drive motor 138 drives the rotating plate 136 to rotate. Through the two sets of push columns 137, the two sets of slide blocks 153 and limit frame 154 move inward, thereby driving the two sets of transmission rollers 155 to move inward, clamping the sling 300. At the same time, the drive motor 163 stops, so that the assembly shell 120 stays on the sling 300. After that, the drive servo motor 191 drives the servo motor 193 at the top of the swing arm 192 to rotate. The drive servo motor 193 drives the infrared probe 194 to rotate, thereby conducting a detailed detection of the water seepage in the area.
