Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building exterior wall seepage detection device for building construction projects. Background Technology

[0002] Building exterior walls have functions such as water resistance, moisture resistance, and high temperature resistance. Often, after the construction of building exterior walls is completed, water seepage testing is required. During the water seepage testing of building exterior walls, water needs to be sprayed onto the building exterior walls to soak the walls. After a period of time, the testing personnel check the interior walls for water stains to determine the water seepage capacity of the building exterior walls.

[0003] However, existing building exterior wall seepage detection equipment still has certain problems:

[0004] For example, a building exterior wall seepage detection device for building construction projects with application number CN202121750125.8 relates to the field of exterior wall seepage detection technology. It includes an adjusting column, a base and a water tank. The top of the base is equipped with sleeves on both sides, and the adjusting column is slidably connected inside the sleeve. The top of the adjusting column is equipped with a top plate. An adjusting structure is provided at the middle position of the bottom end of the top plate. A collection structure is provided at the middle position of the top of the base. Support structures are provided on both sides of one end of the base.

[0005] Existing methods for detecting water seepage in building exterior walls mainly rely on manual visual inspection. Manual visual inspection is inefficient and difficult to detect some subtle water seepage traces. Moreover, it is difficult to conduct comprehensive inspections of complex structures such as building corners and curved exterior walls, which limits the demand for inspections and affects the efficiency of inspection.

[0006] Therefore, we propose a building exterior wall seepage detection device for building construction projects to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a building exterior wall seepage detection device for building construction projects, in order to solve the problems of the building exterior wall seepage detection methods proposed in the background art, which mainly rely on manual visual observation. Manual visual observation is inefficient and difficult to detect some subtle seepage traces. Moreover, it is difficult to conduct all-round detection on complex structures such as building corners and curved exterior walls, which limits the detection needs and affects the efficiency of detection.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a building exterior wall seepage detection device for building construction projects, comprising a vehicle body and a controller. The controller is installed on the top of the vehicle body, and a frame is provided on the upper surface of the vehicle body. Two sets of first sliding grooves are symmetrically opened on the inner side of the frame. A first motor is installed at the top of the frame, and a lead screw is movably connected to the output end of the first motor. A slide block is threaded to the outer surface of the lead screw. First sliders that are slidably connected to the first sliding grooves are fixed on both sides of the slide block. An electric push rod is installed on the outer side of the slide block, and a detection head is fixed to the output end of the electric push rod. A bearing is embedded in the upper surface of the vehicle body, and a third motor is installed inside the vehicle body. A drive shaft is movably connected to the output end of the third motor. A first bevel tooth is fixed to the outer surface of the drive shaft, and a second bevel tooth meshes with the outer surface of the first bevel tooth. A transmission shaft is fixed to the upper surface of the second bevel tooth, and the transmission shaft passes through the middle of the bearing and is fixedly connected to the bottom of the frame.

[0009] Using the above technical solution, the third motor drives the first bevel gear through the drive shaft, and through meshing with the second bevel gear, the transmission shaft rotates within the bearing, realizing the horizontal rotation of the frame; the first motor drives the lead screw to rotate, causing the slide to move up and down along the first slide groove, which, together with the electric push rod, pushes the detection head to move horizontally, allowing the detection head to be positioned in multiple directions, enabling the detection head to flexibly adjust the detection orientation, expanding the detection range of different areas of the exterior wall, improving the comprehensiveness and convenience of the equipment detection, and effectively detecting water seepage in the exterior wall.

[0010] Preferably, a plurality of humidity sensors are mounted on the outer surface of the detection head, and the humidity sensors are arranged in a rectangular array. An infrared detector is mounted at the center of the detection head.

[0011] Using the above technical solution, the humidity sensor detects humidity by sensing changes in the water molecule content on the exterior wall surface, and the infrared detector captures the temperature distribution differences on the exterior wall using the principle of infrared radiation. The two sensors obtain wall information from the dimensions of humidity and temperature, respectively. The rectangular array of humidity sensors can comprehensively and accurately detect wall humidity, and the infrared detector can intuitively present the wall temperature field. The combination of the two can quickly and accurately determine whether there is water seepage on the exterior wall and the location and extent of the seepage.

[0012] Preferably, a water tank is placed on top of the vehicle body, and a water pump is connected to the outside of the water tank through a connecting pipe. A water supply pipe is connected to the middle of the water pump, and a nozzle is installed at the top of the water supply pipe, extending to one side of the detection head. A valve is installed between the water supply pipe and the nozzle.

[0013] Using the above technical solution, the water tank is used to store the water required for testing, and the water pump provides power to deliver the water to the nozzles, simulating rainfall to spray water on the exterior wall, assisting in the detection of water seepage on the exterior wall under different water spraying conditions; the nozzles extend to one side of the detection head, which can spray water more accurately in the detection area of ​​the detection head, making the detection environment more realistic; the valves can flexibly control the water flow, opening or closing the spray at any time according to the detection needs, and can also adjust the water volume to meet the requirements of diverse detection scenarios.

[0014] Preferably, a mounting base is fixed on one side of the detection head, and two sets of second sliding grooves are symmetrically opened on the outer side of the mounting base. A second motor is mounted on the upper end face of the mounting base, and a reverse threaded rod is movably connected to the output end of the second motor. Two sets of second sliders are threadedly connected to the outer surface of the reverse threaded rod, and a clamping plate is fixed on the outer side of the two sets of second sliders. An anti-slip pad is adhered to the clamping surface of the clamping plate.

[0015] Using the above technical solution, the second motor drives the reverse threaded rod to rotate. Due to the reverse thread design, the two sets of second sliders will move towards or away from each other along the second slide groove, thereby driving the clamping plate to open and close. The anti-slip pad increases the friction to assist in clamping. The clamping plate spacing can be flexibly adjusted, which can stably clamp the outer surface of the nozzle. The anti-slip pad can prevent the nozzle from slipping, improve the accuracy of the nozzle spraying water, and ensure the convenience and stability of the testing work.

[0016] Preferably, the water supply pipe is a retractable flexible hose, and the nozzle is a rigid pipe structure.

[0017] Using the above technical solution, the water supply pipe with a telescopic flexible hose structure can freely extend and retract to change its length according to the movement of the detection head, while the nozzle with a rigid pipe structure can maintain a fixed shape and spray direction. The two work together to adapt to the position changes of the detection head. The telescopicity of the water supply pipe ensures that the water path is unobstructed when the detection equipment is detecting at different positions, and the rigid structure of the nozzle ensures that the spray direction is stable and accurate, thereby effectively simulating rainfall to detect water seepage on the exterior wall.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

The third motor drives the first bevel gear through the drive shaft, and through meshing with the second bevel gear, the transmission shaft rotates in the bearing, realizing the horizontal rotation of the stand; the first motor drives the lead screw to rotate, causing the slide to move up and down along the first slide groove, which, together with the electric push rod, pushes the detection head to move horizontally, allowing the detection head to be positioned in multiple directions, enabling the detection head to flexibly adjust the detection direction, expanding the detection range of different areas of the exterior wall, improving the comprehensiveness and convenience of the equipment detection, and effectively detecting water seepage in the exterior wall;

[0020] 2. The humidity sensor detects humidity by sensing changes in the water molecule content on the exterior wall surface, while the infrared detector captures differences in the temperature distribution of the exterior wall using the principle of infrared radiation. The two sensors obtain wall information from the dimensions of humidity and temperature, respectively. The rectangular array of humidity sensors can comprehensively and accurately detect wall humidity, while the infrared detector can intuitively present the wall temperature field. The combination of the two can quickly and accurately determine whether there is water seepage on the exterior wall and the location and extent of the seepage. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-5This utility model provides a technical solution: a building exterior wall seepage detection device for building construction projects, including a vehicle body 1 and a controller 2. The controller 2 is installed on the top of the vehicle body 1. A stand 3 is provided on the upper end of the vehicle body 1. Two sets of first sliding grooves 4 are symmetrically opened on the inner side of the stand 3. A first motor 5 is installed at the top of the stand 3. A lead screw 6 is movably connected to the output end of the first motor 5. A slide seat 7 is threadedly connected to the outer surface of the lead screw 6. First sliders 8 that are slidably connected to the first sliding grooves 4 are fixed on both sides of the slide seat 7. An electric push rod 9 is installed on the outer side of the slide seat 7. A detection head 10 is fixed to the output end of the electric push rod 9. A plurality of humidity sensors 11 are installed on the outer surface of the detection head 10, and the humidity sensors 11 are distributed in a rectangular array. An infrared detector 12 is installed at the center of the detection head 10.

[0029] The vehicle body 1 serves as the basic support, and the controller 2 installed on it is used to coordinate the operation of the equipment. The upright frame 3 on the upper surface of the vehicle body 1 provides the mounting and moving track for the detection components. The two sets of first sliding grooves 4 symmetrically arranged on the inner side of the upright frame 3 cooperate with the first sliders 8 on both sides of the slide block 7, enabling the slide block 7 to slide stably. After the first motor 5 at the top of the upright frame 3 is started, its output end drives the lead screw 6 to rotate. Since the lead screw 6 is threadedly connected to the slide block 7, it drives the slide block 7 to move up and down along the first sliding groove 4, realizing the vertical position adjustment of the detection head 10; the electric push rod 9 on the outer side of the slide block 7 can... The telescopic mechanism allows the detection head 10 to move horizontally, enabling it to reach different locations on the exterior wall for detection. The humidity sensors 11 on the outer surface of the detection head 10 are arranged in a rectangular array, which can comprehensively and accurately detect humidity changes at various points on the exterior wall surface and promptly detect signs of water seepage. The infrared detector 12 at the center of the detection head 10 can capture infrared radiation from the exterior wall surface. By analyzing temperature differences, it can intuitively present whether there are any water seepage points on the exterior wall, as well as the extent and degree of water seepage, providing comprehensive and reliable data support for accurately judging the water seepage situation on the exterior wall.

[0030] A water tank 13 is placed on top of the vehicle body 1. A water pump 14 is connected to the outside of the water tank 13 via a connecting pipe. A water supply pipe 15 is connected to the middle of the water pump 14. A nozzle 16 is installed at the top of the water supply pipe 15 and extends to one side of the detection head 10. A valve 17 is installed between the water supply pipe 15 and the nozzle 16. The water supply pipe 15 is a flexible hose, and the nozzle 16 is a rigid pipe structure. A mounting base 18 is fixed to one side of the detection head 10. Two sets of second sliding grooves 19 are symmetrically opened on the outside of the mounting base 18. A second motor 20 is installed on the upper end of the mounting base 18. A reverse threaded rod 21 is movably connected to the output end of the second motor 20. Two sets of second sliders 22 are threadedly connected to the outer surface of the reverse threaded rod 21. A clamping plate 23 is fixed to the outside of the two sets of second sliders 22. An anti-slip pad 24 is adhered to the clamping surface of the clamping plate 23.

[0031] The water tank 13 on top of the vehicle body 1 is used to store the test water. The water pump 14 draws water from the water tank 13 through the connecting pipe and delivers it to the nozzle 16 through the water supply pipe 15. The valve 17 can control the water flow to simulate rainfall and conduct a water spray test on the outer wall to assist in detecting water seepage. The water supply pipe 15 is a telescopic hose that can freely extend and retract with the position of the test head 10 to ensure unobstructed water flow. The nozzle 16 has a rigid pipe structure to maintain a stable spray direction. The second motor 20 on the mounting base 18 on one side of the test head 10 drives the reverse threaded rod 21 to rotate, causing the two sets of second sliders 22 to move towards or away from each other along the second sliding groove 19, driving the clamping plate 23 to open and close. The anti-slip pad 24 can increase the friction, thereby firmly clamping and fixing the nozzle 16 extending to one side of the test head 10. The fixed nozzle 16 moves according to the movement of the test head 10, thereby expanding the spray range, increasing the detection area, and ensuring the flexibility of the detection work.

[0032] A bearing 25 is embedded in the upper end face of the vehicle body 1. A third motor 26 is installed inside the vehicle body 1. The output end of the third motor 26 is movably connected to a drive shaft 27. A first bevel tooth 28 is fixed on the outer surface of the drive shaft 27. A second bevel tooth 29 meshes with the outer surface of the first bevel tooth 28. A transmission shaft 30 is fixed on the upper end face of the second bevel tooth 29. The transmission shaft 30 passes through the middle of the bearing 25 and is fixedly connected to the bottom of the support frame 3.

[0033] After the third motor 26 installed inside the vehicle body 1 starts, its output end drives the drive shaft 27 to rotate. The first bevel tooth 28 fixed on the outer surface of the drive shaft 27 rotates accordingly. Since the first bevel tooth 28 and the second bevel tooth 29 mesh with each other, the second bevel tooth 29 is driven to rotate. The second bevel tooth 29 drives the transmission shaft 30 on the upper end face to rotate stably in the bearing 25 embedded on the upper end face of the vehicle body 1. The transmission shaft 30 is fixedly connected to the bottom of the stand 3, which finally realizes the rotation of the stand 3 in the horizontal direction. This allows the detection head 10 and the spray head 16 installed on the stand 3 to flexibly adjust the detection position and spray angle, expand the detection range of different areas of the outer wall, realize multi-angle detection in the horizontal direction, and improve the comprehensiveness and convenience of equipment detection.

[0034] Working principle: For this type of building exterior wall seepage detection equipment used in building construction projects, during operation, the third motor 26 inside the vehicle body 1 drives the first bevel gear 28 to rotate via the drive shaft 27. This, in turn, meshes with the second bevel gear 29, causing the transmission shaft 30 to rotate within the bearing 25, thereby driving the upright frame 3 to rotate horizontally. At the top of the upright frame 3, the first motor 5 drives the lead screw 6 to rotate, causing the slide 7 to move up and down along the first slide groove 4. This, in conjunction with the electric push rod 9 on the slide 7, pushes the detection head 10 horizontally, achieving multi-directional positioning of the detection head 10. Water in the water tank 13 above the vehicle body 1... Water is pumped by pump 14 and delivered to nozzle 16 via pipe 15. Valve 17 controls the on / off state to simulate rainfall. Pipe 15 is extendable to adapt to the position of detection head 10. Nozzle 16 is driven by a second motor 20 on mounting base 18 on one side of detection head 10, which drives reverse threaded rod 21 to clamp and fix the nozzle, and moves with detection head 10 to expand the spraying range. During detection, humidity sensor 11 in rectangular array on detection head 10 detects changes in humidity on the exterior wall, and central infrared detector 12 captures infrared radiation to analyze temperature differences, providing data support for judging water seepage.

[0035] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
