Description

Technical Field

[0001] This utility model belongs to the field of building wall inspection technology, and in particular relates to a device for detecting hollow areas in building walls. Background Technology

[0002] Detection of hollow walls is a crucial step in the quality acceptance of building projects, directly impacting the safety and durability of structures. Failure to monitor and maintain in a timely manner can lead to a decline in the waterproofing, insulation, and soundproofing performance of walls, and may even cause serious structural problems such as large-scale peeling of wall plaster and difficulty in tightly adhering and fixing decorative materials, posing a potential threat to personal safety. In the field of building project quality inspection, the detection of hollow walls is of paramount importance, which has led to a growing demand for specialized testing equipment.

[0003] A Chinese patent application with publication number CN113671031B discloses a method and apparatus for detecting hollow walls. The method includes: acquiring an audio signal generated by tapping the wall; acquiring a first feature and a second feature of the audio signal; splicing the first feature and the second feature to obtain a spliced ​​feature; acquiring a recognition result corresponding to the spliced ​​feature based on a preset audio detection network model; and determining whether the wall is in a hollow state based on the recognition result. This method can improve the accuracy of hollow wall detection while reducing labor costs.

[0004] While the above-mentioned equipment can be effective in detecting hollow walls, different wall materials have varying degrees of adaptability to the testing equipment, which may affect the testing results. For example, existing wall hollow detection devices typically require manual tapping of each area multiple times to confirm the presence of hollow areas, increasing the testing time. In large-scale construction projects, the testing work is exceptionally arduous and time-consuming. The experience, force, and tapping method of different operators can all affect the test results, leading to missed or false detections. When testing walls at high altitudes, the sound cannot be clearly heard by the operator, further reducing the accuracy of the judgment. Fixed tapping balls can also develop sharp edges after long-term wear in the same area, easily scratching the wall surface and causing trouble for later repairs.

[0005] To address this issue, we provide a device for detecting hollow areas in building walls. Utility Model Content

[0006] The purpose of this utility model is to provide a wall hollow detection device. By combining the detection component and the extension component, it solves the problems in the prior art where the detection results may be affected by the experience, force and tapping method of different operators, and the fixed tapping ball is prone to scratching the wall surface after long-term use.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a device for detecting hollow areas in building walls, comprising a fixed plate, a detection component at the bottom of the fixed plate, a marking component fixedly connected to one side of the fixed plate, a connecting component fixedly connected to the bottom side of the fixed plate, an extension component at the bottom of the connecting component, and a base for the detection component. The bases are equidistant from each other, with the top of the base fixedly connected to the fixed plate. A contact plate is located on the top of the base, and a first upright is fixedly connected to the bottom of the contact plate. A first limiting plate is fixedly connected to the bottom of the first upright, and a first spring is fixedly connected to the bottom of the first limiting plate. The top of the base is bolted to the bottom of the fixed plate. The contact plate, being a circular plate structure, has the first upright extending vertically downward from its bottom center. The diameter of the first limiting plate matches the inner diameter of the base cavity, allowing it to slide up and down along the inner wall of the base without tilting or jamming. The top end of the first spring is fixedly connected to the bottom end of the first spring, which is fixed to the center of the bottom of the inner cavity of the base. In its natural state, the first spring is slightly extended, pushing the first limiting plate upward so that the top of the contact plate is higher than the top surface of the base, maintaining a ready state for contact with the wall. This device forms a matrix detection structure through the contact plates, which can cover a large wall area at one time, improving detection efficiency. During detection, the contact plates are in contact with the wall surface. When encountering a hollow area, the contact plate will be displaced due to the hollow inside the wall, causing the first upright to move synchronously, which compresses the first spring with the first limiting plate. At the same time, the marker plate moves with the contact plate, and the position of the hollow area can be directly observed by the position change of the marker plate. Since each contact plate cooperates with the base through an independent first upright, first limiting plate and first spring, the displacement of a single contact plate will not interfere with the detection state of other contact plates, ensuring the continuity and stability of the detection process and guaranteeing the reliability of the detection results.

[0009] The present invention is further configured such that the marking assembly includes a stabilizing rod, one side of which is fixedly connected to a fixing plate, and a mounting tube is fixedly connected to the top of the stabilizing rod. A limiting plate is fitted inside the mounting tube, and a threaded rod is movably connected to the bottom of the limiting plate via a rotating shaft. One side of the threaded rod penetrates the surface of the mounting tube and is fixedly connected to a tensioning rod. The mounting tube and the limiting plate cooperate to form a reliable adjustment base. The operator rotates the tensioning rod to drive the threaded rod to rotate, thereby adjusting the position of the limiting plate inside the mounting tube. This adapts to different marking devices, improves the adaptability and ease of operation of the marking assembly, and ensures the accuracy of marking void positions.

[0010] The present invention is further configured such that a second upright is fixedly connected to the bottom of the first limiting plate, and a marker plate is fixedly connected to the bottom of the second upright. The second upright moves the marker plate through the displacement of the first limiting plate, so that the marker plate can synchronously reflect the position change of the contact plate. This direct transmission relationship ensures the timeliness and accuracy of the hollow detection signal transmission. The operator can identify the hollow area by observing the state of the marker plate, which simplifies the detection and judgment process and improves the efficiency of hollow identification.

[0011] The present invention is further configured such that the connecting assembly includes four connecting rods, one side of which is fixedly connected to a fixed plate and the other side of which is fixedly connected to a stabilizing plate. A fixed rod is fixedly connected to one side of the stabilizing plate. The four connecting rods form a stable support structure, which evenly distributes the force on the fixed plate to the stabilizing plate, thereby enhancing the overall structural strength and stability of the device.

[0012] The present invention is further configured such that the extension assembly includes a first extension rod, one side of which is threadedly connected to a fixed rod, a second extension rod is sleeved on the surface of the first extension rod, and a limiting mechanism is sleeved in the inner cavity of the first extension rod. The threaded connection between the first extension rod and the fixed rod facilitates the disassembly and assembly of the extension assembly and the initial length adjustment. The second extension rod sleeved on the surface of the first extension rod realizes the extension and retraction of the length. With the help of the limiting mechanism, different extension lengths are fixed. This design allows the device to flexibly adapt to wall inspection at different heights, and can complete high-altitude operations without additional auxiliary tools, thus expanding the applicability of the device.

[0013] The present invention is further configured such that the limiting mechanism includes a second spring, the bottom of the second spring is fixedly connected to the first extension rod, and the top of the second spring is fixedly connected to a second limiting plate. The elastic force of the second spring can push the second limiting plate to achieve stable limitation on the relative position of the first extension rod and the second extension rod. When it is necessary to adjust the extension length, simply press the second limiting plate to change the limiting state. The operation is simple and can ensure the structural stability after adjustment, avoid accidental slippage during the extension process, and improve the safety of the device.

[0014] The present invention is further configured such that a first baffle is fixedly connected to one side of the second extension rod, a gripping rod is fixedly connected to one side of the first baffle, and a second baffle is fixedly connected to one side of the gripping rod. The gripping rod provides a comfortable gripping position for the operator, making it easy to apply force for wall detection operations. The first baffle and the second baffle can prevent the hand from slipping off the gripping rod during operation, thus improving the overall operating experience.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses multiple contact plates arranged in a matrix to cover a certain wall area. When the wall is being inspected, if a contact plate encounters a hollow area, the contact plate will shift. At the same time, due to the cooperation of the contact plate, the first limiting plate, the first upright, the second upright and the first spring, the marking plate will move synchronously without affecting the normal inspection of other contact plates, thus ensuring the continuity and stability of the inspection.

[0017] 2. This utility model, through the combined use of the first extension rod and the second extension rod, along with the second spring and the second limiting plate, enables the device to be easily extended to a higher height while maintaining stability. This design allows operators to complete the inspection of high walls without the need for ladders or other auxiliary tools, which improves work efficiency and reduces the risks of working at heights.

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

[0028] Example 1

[0029] Please see Figure 1-7 This utility model is a device for detecting hollow walls in building structures, including a fixed plate 1, a detection component 2 at the bottom of the fixed plate 1, a marking component 3 fixedly connected to one side of the fixed plate 1, a connecting component 4 fixedly connected to one side of the bottom of the fixed plate 1, an extension component 5 at the bottom of the connecting component 4, a base 21 at which the bases 21 are equidistantly arranged, a contact plate 22 at the top of the base 21, a first upright 23 fixedly connected to the bottom of the contact plate 22, a first limiting plate 24 fixedly connected to the bottom of the first upright 23, and a first spring 25 fixedly connected to the bottom of the first limiting plate 24.

[0030] Specifically: The top of the base 21 is fixed to the bottom of the fixing plate 1 by bolts. A contact plate 22 is embedded in the top of the base 21. The contact plate 22 is a circular plate structure, with a first upright 23 extending vertically downward from the bottom center. The diameter of the first limiting plate 24 is adapted to the inner diameter of the base 21, allowing it to slide up and down along the inner wall of the base 21 without tilting or jamming. The bottom center of the first limiting plate 24 is fixedly connected to the top of the first spring 25, and the bottom end of the first spring 25 is fixed to the bottom center of the inner cavity of the base 21. In its natural state, the first spring 25 is in a slightly extended state, pushing the first limiting plate 24 upward, so that the top of the contact plate 22 is higher than the top surface of the base 21, maintaining a ready state for contact with the wall. The contact plates 22 form a matrix detection structure, which can cover a large wall area at once, improving detection efficiency. During detection, the contact plates 22 are in contact with the wall surface. When encountering a hollow area, the contact plates 22 will be displaced due to the hollow inside the wall, causing the first upright 23 to move synchronously. This causes the first limiting plate 24 to compress the first spring 25. At the same time, the marker plate 7 moves with the contact plates 22. The position of the hollow area can be directly observed by the position change of the marker plate 7. Since each contact plate 22 cooperates with the base 21 through an independent first upright 23, first limiting plate 24 and first spring 25, the displacement of a single contact plate 22 will not interfere with the detection status of other contact plates 22, ensuring the continuity and stability of the detection process and guaranteeing the reliability of the detection results.

[0031] Example 2

[0032] Please see Figure 1-7 Based on Embodiment 1, the marking component 3 includes a stabilizing rod 31, with a mounting tube 32 fixedly connected to the top of the stabilizing rod 31. A limiting plate 33 is fitted inside the mounting tube 32. One side of the stabilizing rod 31 is fixedly connected to a fixing plate 1. A threaded rod 34 is movably connected to the bottom of the limiting plate 33 via a pivot. One side of the threaded rod 34 penetrates the surface of the mounting tube 32 and is fixedly connected to a tensioning rod 35. A second upright 6 is fixedly connected to the bottom of the first limiting plate 24. A marking plate 7 is fixedly connected to the bottom of the second upright 6. The connecting component 4 includes four connecting rods 41. One side of the connecting rod 41 is fixedly connected to the fixing plate 1, and the other side of the connecting rod 41 is fixedly connected to the stabilizing rod 31. The plate 42 is fixedly connected, and a fixing rod 43 is fixedly connected to one side of the stabilizing plate 42. The extension component 5 includes a first extension rod 51, one side of which is threadedly connected to the fixing rod 43. A second extension rod 52 is sleeved on the surface of the first extension rod 51. A limiting mechanism 53 is sleeved in the inner cavity of the first extension rod 51. The limiting mechanism 53 includes a second spring 531, the bottom of which is fixedly connected to the first extension rod 51. A second limiting plate 532 is fixedly connected to the top of the second spring 531. A first baffle 8 is fixedly connected to one side of the second extension rod 52. A gripping rod 9 is fixedly connected to one side of the first baffle 8. A second baffle 10 is fixedly connected to one side of the gripping rod 9.

[0033] Specifically: A reliable adjustment base is formed by the cooperation of the mounting tube 32 and the limiting plate 33. The operator rotates the tension rod 35 to drive the threaded rod 34 to rotate, thereby adjusting the position of the limiting plate 33 within the mounting tube 32. This adapts to different marking devices, improving the adaptability and ease of operation of the marking assembly 3 and ensuring the accuracy of hollow area marking. The second upright rod 6 moves the marker plate 7 through the displacement of the first limiting plate 24, allowing the marker plate 7 to synchronously reflect the positional changes of the contact plate 22. This direct transmission relationship ensures the timeliness and accuracy of hollow area detection signal transmission. The operator identifies the hollow area by observing the state of the marker plate 7, simplifying the detection and judgment process and improving the efficiency of hollow area identification. The four connecting rods 41 form a stable support structure, evenly distributing the force on the fixed plate 1 to the stable plate 42, enhancing the overall structural strength and stability of the device. The threaded connection between the first extension rod 51 and the fixed rod 43 facilitates the disassembly and assembly of the extension assembly 5. With initial length adjustment, the second extension rod 52 is sleeved on the surface of the first extension rod 51 to achieve length extension and contraction. Combined with the limiting mechanism 53, different extension lengths are fixed. This design allows the device to flexibly adapt to wall inspections at different heights, enabling high-altitude operations without additional auxiliary tools, thus expanding the device's applicability. The elastic force of the second spring 531 pushes the second limiting plate 532, achieving stable limitation on the relative position of the first extension rod 51 and the second extension rod 52. When the extension length needs adjustment, simply press the second limiting plate 532 to change the limiting state. This simple operation ensures structural stability after adjustment, preventing accidental slippage during extension and improving the safety of the device. The grip rod 9 provides a comfortable grip for operators, facilitating the application of force for wall inspection. The first baffle 8 and the second baffle 10 prevent hands from slipping off the grip rod 9 during operation, enhancing the overall operating experience.

[0034] The working principle of this utility model is as follows: Before wall detection, the operator holds the gripping rod 9 and presses the second limiting plate 532. The second limiting plate 532 compresses the second spring 531 and moves downward, releasing the restriction on the relative position of the first extension rod 51 and the second extension rod 52. Then, the operator pushes the second extension rod 52, causing it to slide along the surface of the first extension rod 51 until the device length is adapted to the wall detection height. At the start of the detection, the operator holds the device's detection component 2 towards the wall through the gripping rod 9, so that the contact plate 22 is in contact with the wall surface. Under natural conditions, the first spring 25 is in a slightly extended state, and its elastic force is transmitted to the contact plate 22 through the first limiting plate 24 and the first upright rod 23, ensuring that the contact plate 22 is always in a stable position. When in close contact with the wall surface, if the area corresponding to the contact plate 22 is a hollow area, the contact plate 22 will displace into the base 21, causing the first upright 23 to move synchronously. The first upright 23 will further push the first limiting plate 24 to compress the first spring 25, thereby causing the marker plate 7 to change position. The position of the hollow area can be intuitively presented by the displacement of the marker plate 7. If it is necessary to mark the hollow area, the operator will rotate the tension rod 35 in the marking assembly 3 in advance. The tension rod 35 will drive the threaded rod 34 to rotate in the mounting tube 32. The threaded rod 34 will push the limiting plate 33 to slide through the rotating shaft, adjust the position of the limiting plate 33 to fix the marking device, and then mark the hollow area indicated by the marker plate 7.

[0035] Throughout the testing process, the base 21 is stably connected to the fixed plate 1 by bolts. The four connecting rods 41 evenly distribute the force on the fixed plate 1 to the stabilizing plate 42, and then transmit it to the fixed rod 43 and the extension assembly 5 through the stabilizing plate 42, ensuring the overall stability of the device structure and avoiding testing deviations due to uneven force. At the same time, each contact plate 22 is coordinated with an independent first upright rod 23, a first limiting plate 24 and a first spring 25. The displacement of a single contact plate 22 will not interfere with the testing status of other contact plates 22, ensuring the continuity of the testing process and the reliability of the testing results.
