Description

Technical Field

[0001] This invention belongs to the field of building interior wall inspection technology, specifically a building interior wall verticality inspection device. Background Technology

[0002] The verticality of interior walls is a commonly used quality indicator in building decoration and acceptance. Current on-site testing typically uses a straightedge and feeler gauge, or a spirit level and plumb line for comparison, and sometimes laser levels are used. These methods mostly require the operator to stop at multiple points on the wall, align with the baseline, and visually read or record the measurements. The measurement process is greatly affected by visibility conditions and the operator's skill level. For long or high walls, repeated movement and multiple alignments are necessary, which is inefficient. Furthermore, in construction environments with complex lighting, high dust levels, or confined spaces, the stability of readings and alignment can easily decrease.

[0003] To improve portability and intuitiveness, some solutions utilize gravity pendulums to detect tilt. Some solutions incorporate electronic angle sensors and display or alarm units, providing numerical output, but these have higher structural costs and maintenance requirements, and are more sensitive to on-site factors such as drops, impacts, dust, and vibrations. While some purely mechanical solutions do not rely on electronic components, their triggering structures often suffer from unstable thresholds, sensitivity drift due to friction and wear, or false triggering caused by localized protrusions and deposits on the wall. Furthermore, existing solutions have limited ability to indicate tilt direction and tilt level, making it difficult to quickly distinguish and reproduce judgments during continuous movement along a wall.

[0004] Therefore, it is necessary to provide a wall verticality detection device suitable for construction sites, which can provide intuitive feedback as it moves along the wall and reduce the impact of false triggering caused by local protrusions and attachments. Summary of the Invention

[0005] The purpose of this invention is to provide a device for detecting the verticality of interior walls in buildings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the verticality of interior walls of buildings, comprising: A mobile frame, wherein the mobile frame is provided with a guide mechanism for moving to conform to the wall surface; A gravity sensing component, pivotally connected within the movable frame, includes a pendulum that swings relative to the tilt of the movable frame, and a triggering magnetic element is provided at the lower end of the pendulum. Acoustic feedback components, including a reciprocating motion unit and a magnetic repulsion triggering unit; The reciprocating motion unit includes an interference element and a driving source, and the driving source drives the interference element to be in a continuous reciprocating motion state. The magnetic repulsion triggering unit includes an impact member that is elastically held in a non-triggering position, and a force-receiving magnetic member disposed on the impact member and opposite to the same pole of the triggering magnetic member. When the moving frame tilts and aligns the triggering magnetic component with the force-bearing magnetic component, the magnetic repulsion between the two drives the impact component to overcome the elastic force and move, causing the impact component to enter the movement trajectory of the interference component and undergo a mechanical collision, thereby emitting an audible signal.

[0007] Preferably, the gravity sensing component further includes a rotating shaft and a traction unit; the rotating shaft is horizontally mounted between the inner walls of the moving frame via bearings, and the traction unit connects the rotating shaft and the pendulum; the triggering magnetic component is constructed as a magnetic rod vertically fixed at the bottom of the pendulum, and the bottom end of the magnetic rod is machined into a cone shape.

[0008] Preferably, the magnetic repulsion triggering unit further includes a support arc-shaped platform fixed in the mobile frame, the top surface of which is arc-shaped and located below the pendulum swing trajectory; The supporting arc-shaped platform has several sets of through mounting holes, and the impact component and the force-receiving magnetic component are movably sleeved in the mounting holes. The impact component includes an assembly rod and an impact head located at the bottom of the assembly rod. A return spring is sleeved around the assembly rod. A support sleeve is provided at the bottom of the supporting arc-shaped platform. The return spring is fixedly connected between the force-receiving magnetic component and the support sleeve to keep the force-receiving magnetic component in the mounting hole.

[0009] Preferably, the mounting holes are divided into two groups, left and right, and symmetrically distributed on both sides of the supporting arc-shaped platform, with multiple mounting holes in the same group arranged at equal intervals along the arc surface; The triggering magnetic element is located in the central region between the two sets of mounting holes in the initial vertical state.

[0010] Preferably, the reciprocating motion unit further includes: The fixed sleeve is fixed inside the mobile frame; A movable crank is slidably sleeved inside the fixed crank sleeve, and an elastic element is connected in the fixed crank sleeve. The elastic element is fixedly connected to the end of the movable crank. An arc-shaped plate is connected to the other end of the movable crank rod, and the interference element is constructed as a plurality of excitation plates arranged in an array on the inner wall of the arc-shaped plate.

[0011] Preferably, the reciprocating motion unit further includes a magnetic drive mechanism for converting rotational motion into the reciprocating oscillation of the arc plate; The magnetic drive mechanism includes a driven magnetic block disposed on the outer wall of the arc-shaped plate, and an active magnetic block driven to rotate by a drive source. The active magnetic block is configured to periodically approach and repel the driven magnetic block during rotation, thereby pushing the movable crank to compress the elastic element, and restoring it using the restoring force of the elastic element when it moves away.

[0012] Preferably, the driving source is a motor; the output shaft of the motor is connected to a rotating fan blade, the mobile frame is provided with an air duct, the rotating fan blade is located on the air inlet side of the air duct, the mobile frame is provided with an air outlet, the air duct is connected to the air outlet, and air is discharged through the air outlet toward the contact area between the guide mechanism and the wall, for blowing away the wall attachments during the detection process.

[0013] Preferably, the impact head at the bottom of the impact member is detachably connected; the impact heads located in different mounting holes are made of different materials and are configured to emit different timbres when colliding with the interference member to distinguish the tilt level.

[0014] Preferably, the mobile frame is externally connected to a support arm for handheld operation; the guiding mechanism consists of casters mounted vertically on the side of the mobile frame.

[0015] A method for detecting the verticality of interior walls in buildings includes the following steps: Step 1: Start-up and bonding. Start the motor to drive the interference component in a continuous reciprocating motion. The guide mechanism area is continuously purged through the air duct, and the moving frame is bonded to the wall to be tested. Step 2: Motion detection, the mobile frame is continuously moved vertically along the wall by the support arm; Step 3: Sound identification. Determine the wall verticality based on whether sound is generated during the movement and the characteristics of the sound: If a short and discontinuous sound is emitted and then disappears, it is determined to be a local protrusion on the wall or interference from non-structural attachments, and is not recorded; if a continuous mechanical collision sound is emitted, it is determined that the verticality of the wall in that area is out of tolerance; if a continuous collision sound with different timbres is emitted, the current tilt level is identified based on the preset correspondence between the material of the impactor and the timbre.

[0016] The beneficial effects of this invention are as follows: 1. This invention forms a moving base that rolls along the wall by using a moving frame and a guiding mechanism. With the help of a gravity sensing component, it realizes real-time perception of the tilt state of the moving frame, so that the detection process can be carried out continuously while moving along the wall. This reduces the operational burden caused by stopping at each point for alignment and visual reading, and improves the efficiency of inspection.

[0017] 2. This invention uses a pendulum and a triggering magnetic component as the tilting trigger source, and utilizes the magnetic force of the force-bearing magnetic component and the impact component to achieve trigger displacement. This makes the triggering process mainly based on magnetic coupling, reducing the friction, wear and jamming probability of the purely mechanical toggle structure, which is conducive to maintaining the long-term stability of the trigger threshold.

[0018] 3. The present invention sets up a reciprocating motion unit to keep the interfering element in a continuous reciprocating motion state, and maintains the gap between the impact head and the interfering element when the magnetic repulsion triggering unit is not triggered, so as to avoid ineffective friction and noise; when triggered, the impact head enters the motion trajectory of the interfering element and collides, thereby converting the tilted state of the wall into an acoustic signal, and the feedback form is intuitive.

[0019] 4. The present invention sets mounting holes in left and right groups and distributed along the arc surface on the supporting arc platform, so that the deflection of the pendulum can be triggered by different hole positions, thereby realizing the differentiation of tilt direction; at the same time, the tilt level classification is formed by the hole position distribution density and hole position sequence, which facilitates the improvement of discrimination ability without introducing electronic sensors.

[0020] 5. The present invention sets the impact head as a detachable structure, and impact heads of different materials can be configured in different mounting holes so that they produce different timbres when they collide with the exciter, thereby providing a more intuitive level indication method, facilitating quick on-site judgment and verification, and also facilitating replacement and maintenance after wear.

[0021] 6. Based on the structure of the motor driving the rotating fan blades and blowing towards the contact area between the guide mechanism and the wall through the air duct, the present invention can reduce the caster jumping and momentary deflection caused by dust particles and other adhering objects, reduce the probability of short false triggers, and thus improve the stability and repeatability of the motion detection process.

Detailed Implementation Example

[0024] like Figures 1 to 8 As shown, this embodiment provides a building interior wall verticality detection device, including a movable frame 1, a guide mechanism 2, a gravity sensing component 3, and an acoustic feedback component. The movable frame 1 is used to support the various functional components and form an overall frame that can move along the wall surface. It can be constructed as a shell structure or a frame structure, and has an internal mounting cavity for installing the gravity sensing component 3, the reciprocating motion unit 4, and the magnetic repulsion triggering unit 5.

[0025] The guide mechanism 2 is located on the side of the mobile frame 1 facing the wall, and is used to fit against the wall and guide the mobile frame 1 to move smoothly along the wall. The guide mechanism 2 can adopt a caster structure with the upper and lower parts distributed. The casters can be installed on the mobile frame 1 through the axle. The outer circumference of the casters rolls in contact with the wall to reduce the pushing and pulling resistance and reduce the interference of the wall surface attachments on the detection. The mobile frame 1 is externally connected to the support arm 11. The support arm 11 is used for hand-held pushing and pulling operation, so that the mobile frame 1 moves along the wall from top to bottom or from bottom to top for detection.

[0026] The gravity sensing component 3 is pivotally connected inside the movable frame 1 to sense the tilt of the movable frame 1 relative to the vertical direction. The gravity sensing component 3 includes a pendulum 301 and a triggering magnetic component 302. The pendulum 301 swings relative to the movable frame 1 as it tilts. Furthermore, the gravity sensing component 3 also includes a rotating shaft 303 and a traction part 304. The rotating shaft 303 is horizontally mounted between the inner walls of the movable frame 1 via bearings. The traction part 304 connects the rotating shaft 303 and the pendulum 301, allowing the pendulum 301 to swing freely around the rotating shaft 303. The triggering magnetic component 302 is constructed as a magnetic rod vertically fixed to the bottom of the pendulum 301. The bottom end of the magnetic rod is machined into a cone shape to provide a clearer directionality and improve trigger stability during swing positioning.

[0027] The acoustic feedback component includes a reciprocating motion unit 4 and a magnetic repulsion triggering unit 5. The reciprocating motion unit 4 is used to keep the interference element 401 in a continuous reciprocating motion state. The magnetic repulsion triggering unit 5 is used to guide the impact element 501 into the motion trajectory of the interference element 401 when the tilt triggering condition is met, so that the impact element 501 and the interference element 401 will have a mechanical collision and emit a sound signal.

[0028] The reciprocating motion unit 4 includes a fixed curved sleeve 402, a movable curved rod 403, an elastic element 7, an arc-shaped plate 404, and an interference element 401. The fixed curved sleeve 402 is fixedly mounted inside the movable frame 1. The movable curved rod 403 is slidably fitted inside the fixed curved sleeve 402. The elastic element 7 is disposed in the fixed curved sleeve 402 and fixedly connected to the end of the movable curved rod 403, allowing the movable curved rod 403 to reciprocate within the fixed curved sleeve 402 and reset under the elastic action of the elastic element 7. The arc-shaped plate 404 is connected to the other end of the movable curved rod 403. The interference element 401 is constructed as an array of excitation plates arranged on the inner wall of the arc-shaped plate 404. The excitation plates can be of an elastic plate structure, used to form an interference trajectory that can be impacted during the reciprocating motion.

[0029] The reciprocating motion unit 4 also includes a magnetic drive mechanism 405, used to convert rotational motion into reciprocating oscillation of the arc plate 404. The magnetic drive mechanism 405 includes a driven magnetic block 4051 disposed on the outer wall of the arc plate 404, and an active magnetic block 4052 driven to rotate by a drive source. The active magnetic block 4052 is configured to periodically approach and repel the driven magnetic block 4051 during rotation, thereby pushing the arc plate 404 to oscillate and causing the movable crank 403 to compress the elastic element 7. When the active magnetic block 4052 moves away from the driven magnetic block 4051, the restoring force of the elastic element 7 drives the movable crank 403 and the arc plate 404 to reset, realizing the continuous reciprocating motion of the exciter plate on the arc plate 404. The drive source can be a motor 8, and the output shaft of the motor 8 can be connected to the rotating structure of the active magnetic block 4052 to realize continuous rotational drive.

[0030] The magnetic repulsion triggering unit 5 includes a supporting arc-shaped platform 503, mounting holes 504, an impact element 501, a force-receiving magnetic element 502, and a reset elastic structure. The supporting arc-shaped platform 503 is fixed inside the movable frame 1, and its top surface is arc-shaped and located below the swing trajectory of the pendulum 301. Several sets of through mounting holes 504 are opened on the supporting arc-shaped platform 503. The mounting holes 504 can be divided into two groups and symmetrically distributed on both sides of the supporting arc-shaped platform 503. Multiple mounting holes 504 in the same group are arranged at equal intervals along the arc surface, so that different mounting holes 504 correspond to different pendulum deflection positions. The triggering magnetic element 302 is located in the central area between the two sets of mounting holes 504 in the initial vertical state.

[0031] The impact element 501 is movably sleeved within the mounting hole 504 and held in a non-triggered position by the reset elastic structure. The impact element 501 includes an assembly rod 5011 and an impact head 5012 located at the bottom end of the assembly rod 5011. The impact head 5012 is located above the exciter plate of the arc plate 404 and has a pre-reserved gap with the exciter plate, so that the impact head 5012 does not enter the movement trajectory of the interference element 401 when in the non-triggered position. The force-bearing magnetic element 502 is disposed on the impact element 501 and is opposite to the triggering magnetic element 302 with the same pole, thereby generating a magnetic repulsion force when the two are aligned. The reset elastic structure may include a reset spring 6. A support sleeve 12 is provided at the bottom of the supporting arc platform 503. The reset spring 6 is connected between the impact element 501 and the support sleeve 12, so that the impact element 501 is held in an upward non-triggered position when there is no magnetic repulsion force or the magnetic repulsion force is insufficient, and is pushed downward by the elastic force under the push of the magnetic repulsion force.

[0032] Both the triggering magnetic component 302 and the force-receiving magnetic component 502 can be permanent magnets or component structures with permanent magnets. To achieve magnetic repulsion triggering, the opposite end faces of the triggering magnetic component 302 and the force-receiving magnetic component 502 are configured with opposite poles, so that they generate magnetic repulsion when aligned. The triggering magnetic component 302 can be fixed to the mounting position at the bottom of the pendulum 301 by interference fit, adhesive fixation, or pressure plate locking. The force-receiving magnetic component 502 can be fixed to the upper end of the assembly rod 5011 or to the upper part of the impact component 501.

[0033] It is worth noting that this device uses the aforementioned "magnetic repulsion drive" instead of the traditional "mechanical lever contact drive," which has significant technical advantages: the triggering magnetic component 302 and the force-receiving magnetic component 502 always maintain a non-contact state. This means that the pendulum 301 will not be affected by the frictional resistance caused by the mechanical lever structure during the swing positioning process, thus ensuring high sensitivity of gravity sensing. At the same time, the downward movement of the impact component 501 is achieved by the magnetic repulsion force overcoming the spring force, avoiding the wear, jamming, or breakage problems that are prone to occur in rigid transmission structures during long-term reciprocating triggering, and greatly extending the service life of the device in dusty environments.

[0034] A limiting step or limiting retaining ring can be provided on the assembly rod 5011 to cooperate with the supporting arc-shaped platform 503 or the supporting sleeve 12 to form an upper limit. To prevent the impact head 5012 from moving too far downward, causing interference with the arc-shaped plate 404 or damaging the exciter, a lower limiting structure, such as a limiting screw or a limiting shoulder, can be provided between the supporting sleeve 12 and the impact head 5012 to maintain a controllable gap after the impact head 5012 enters the movement trajectory of the interference member 401.

[0035] The elastic force of the reset spring 6 and the elastic element 7 can be set in combination with the trigger sensitivity and the requirements for preventing false alarms. Increasing the elastic force of the reset spring 6 can improve the ability to prevent false triggering, and increasing the elastic force of the elastic element 7 can improve the reciprocating frequency of the excitation plate and the consistency of reset.

[0036] The active magnetic block 4052 is fixedly mounted on the output shaft of the motor 8 via a connecting ring that is fixedly sleeved on the output shaft of the motor 8, and rotates with the output shaft of the motor 8. The installation position of the active magnetic block 4052 relative to the driven magnetic block 4051 is set to be eccentric, so that the active magnetic block 4052 periodically approaches the driven magnetic block 4051 with each revolution and generates a magnetic repulsive force to push the arc plate 404 to shift. Subsequently, as the rotation angle changes, the active magnetic block 4052 gradually moves away from the driven magnetic block 4051, and the arc plate 404 is reset under the action of the elastic element 7.

[0037] In an optional configuration, the impact head 5012 is detachably connected to the lower end of the mounting rod 5011, for example, via a threaded connection. The impact heads 5012 located in different mounting holes 504 are configured to be made of different materials to create a mapping feedback chain of "tilt angle - hole position - material - timbre". Specifically, the impact head 5012 located in the mounting hole 504 near the center of the supporting curved platform 503 (corresponding to a small tilt angle) is made of nylon or hard rubber, which produces a low, muffled sound when colliding with the metal exciter, indicating a slight deviation from tolerance. The impact head 5012 located in the mounting holes 504 on both sides of the supporting curved platform 503 (corresponding to a large tilt angle) is made of stainless steel or copper, which produces a crisp, sharp metallic knocking sound when colliding with the metal exciter, indicating a serious deviation from tolerance. Inspectors can intuitively judge the severity of the wall tilt simply by listening to the difference in timbre (muffled or crisp) without visually inspecting the equipment.

[0038] Before leaving the factory or using the device, calibration can be performed by pushing it onto a standard vertical wall surface to ensure that the trigger magnetic component 302 is centered between the two sets of mounting holes 504 in a vertical position. Centering can be achieved by adjusting the mounting angle of the supporting curved platform 503 or by adjusting the assembly position of the trigger magnetic component 302 and the pendulum 301. Subsequently, the corresponding trigger hole positions and timbre can be recorded on calibration surfaces with different known tilt angles, thereby establishing the correspondence between tilt level and acoustic feedback.

[0039] In this embodiment, the device may also include a purging structure to reduce false alarms. When the drive source is a motor 8, the output shaft of the motor 8 can be connected to a rotating fan blade 9. An air duct 10 is provided on the movable frame 1, and the rotating fan blade 9 is located on the air inlet side of the air duct 10. Specifically, the air duct 10 is connected to the air outlet 15 through the air pipe 14, so that the air volume is discharged through the air outlet 15 towards the contact area between the guide mechanism 2 and the wall, which is used to purge the wall adhering objects during the detection process, reduce the drop-off of the casters caused by particulate matter and improve the detection stability. The air duct 10 can be connected to the air supply duct 13, which is fixed on the inner wall of the movable frame 1 so as to guide the fan blade air volume into the air duct 10.

[0040] Specifically, the motor drives the fan blades 9 to rotate, and the resulting airflow is collected by the air supply duct 13 and guided through the air duct 14 to the air outlet 15 to blow onto the wall. Example

[0041] Based on Embodiment 1, the number of mounting holes 504 and the hole density can be adjusted according to the required grading accuracy. If finer tilt level identification is required, the number of mounting holes 504 can be increased and the hole spacing reduced in the arc direction of the supporting arc platform 503, making it easier for the triggering magnetic element 302 to correspond to different mounting hole 504 positions at different deflection angles, thereby driving the corresponding impact element 501 to produce collision sounds of different timbres or frequencies. Correspondingly, the elasticity of the return spring 6, the sliding fit clearance of the impact element 501, and the initial distance between the triggering magnetic element 302 and the force-receiving magnetic element 502 can be adjusted to meet different sensitivity requirements and avoid false triggering caused by slight vibrations. The above parameters can be set by those skilled in the art according to wall inspection specifications and usage scenarios. Example

[0042] Based on Embodiment 1 or Embodiment 2, in addition to the upper and lower distributed casters, the guide mechanism 2 can also adopt a multi-wheel group or roller strip structure to improve the fit of the mobile frame 1 on the rough wall surface; the support arm 11 can be set as a detachable or telescopic structure to adapt to different working heights and operator postures; in addition to the motor 8, the drive source of the reciprocating motion unit 4 can also be other drive structures that can provide continuous rotation output. The magnetic drive mechanism 405 still realizes the reciprocating swing of the arc plate 404 through the periodic approach and repulsion of the active magnetic block 4052 and the driven magnetic block 4051, thereby ensuring the basic conditions for the continuous movement of the interference member 401.

[0043] Working principle and usage process Step 1: Preparation and Start-up The operator holds the support arm 11, so that the guide mechanism 2 is close to the wall to be measured. The moving frame 1 forms a stable rolling contact with the wall. After the drive source motor 8 is started, the motor 8 drives the active magnetic block 4052 to rotate continuously. During the rotation, the active magnetic block 4052 periodically approaches and repels the driven magnetic block 4051, thereby driving the arc plate 404 to swing back and forth. The excitation plates arranged in the array on the inner wall of the arc plate 404 form the motion trajectory of the interference piece 401 in continuous reciprocating motion. At this time, in the non-triggered state, the impact piece 501 is kept in the non-triggered position under the action of the reset spring 6. The impact head 5012 and the excitation plate maintain a gap, so no continuous collision sound is generated. The second step is to detect movement along the wall. The operator pushes or pulls the support arm 11 to move the mobile frame 1 along the wall from top to bottom or from bottom to top. If the verticality of the wall is qualified and the movement is smooth, the pendulum 301 in the gravity sensing component 3 remains in an approximately vertical state under the action of gravity. The triggering magnetic component 302 is located near the center area between the two sets of mounting holes 504 and does not reach the trigger alignment state with the force-bearing magnetic component 502 in any mounting hole 504. Therefore, the impact component 501 does not move down and the device remains in a state without continuous collision sound. Step 3: Tilt Triggering and Vocal Feedback When the movable frame 1 tilts with the wall or due to the wall not being vertical, the pendulum 301 swings relative to the movable frame 1, causing the trigger magnetic component 302 to shift along the arc direction of the supporting arc platform 503 and approach the corresponding position of a certain mounting hole 504. When the trigger magnetic component 302 and the force-bearing magnetic component 502 in the mounting hole 504 are relatively aligned, the two with the same poles generate a magnetic repulsion force. The magnetic repulsion force drives the impact component 501 to overcome the elastic force of the return spring 6 and move downward, so that the impact head 5012 enters the movement trajectory range of the interference component 401. As the exciter plate of the interference component 401 continues to reciprocate, the impact head 5012 and the exciter plate undergo continuous mechanical collision, thereby forming an audible signal. The operator can directly judge the wall verticality deviation by hearing. Step 4: Distinguishing between short and continuous sounds When the mobile frame 1 quickly passes over a local protrusion on the wall, the pendulum 301 will swing momentarily, and the triggering magnetic component 302 and the force-bearing magnetic component 502 may momentarily align. The impact component 501 will briefly move downward and produce a short collision sound. Then the pendulum 301 returns to its original position, and the impact component 501 is reset by the return spring 6, and the sound ends. The operator judges this short sound as non-structural interference. Conversely, when the mobile frame 1 is in a continuously tilted state, the triggering magnetic component 302 and the force-bearing magnetic component 502 remain aligned, and the impact component 501 remains in the triggered displacement state and continuously collides with the exciter, producing a continuous collision sound. The operator judges this continuous sound as a wall verticality deviation.

[0044] Step 5: Tilt Level Identification and Attachment Interference Suppression As the wall tilt angle changes, the pendulum 301 drives the trigger magnetic component 302 to deflect to different positions, which in turn triggers the impact component 501 in different mounting holes 504 to collide. If the impact head 5012 in different mounting holes 504 is made of different materials, it will produce different timbres when it collides with the exciter. The operator can identify the tilt level of the wall according to the preset timbre and hole position level mapping relationship. During the detection process, the motor 8 drives the fan blade 9 to deliver air volume to the air duct 10. The air outlet of the air duct 10 blows the area in contact between the guide mechanism 2 and the wall, which can reduce the probability of caster jumping caused by attached particles, thereby reducing short false alarms and improving detection stability.
