Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically a high stability testing device for building exterior walls. Background Technology

[0002] Building exterior walls are the external enclosure structures of buildings, the walls that directly contact the building with the external environment. Their core functions are to define building space, resist the influence of the natural environment, and bear certain functions. High-stability testing devices are a type of equipment that can maintain accurate measurement, reliable data output, and stable working state during long-term operation in complex environments.

[0003] Traditional installations often rely on mechanical fixing, such as expansion bolts, which require the wall to have sufficient strength. However, they have poor compatibility with lightweight walls and decorative exterior walls. Expansion bolts may damage the wall structure, easily leading to wall cracks and water seepage. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing high stability testing devices for building exterior walls rely on expansion bolts for fixation, but expansion bolts may damage the wall structure and easily lead to wall cracks and water seepage.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a high stability detection device for building exterior walls includes a box for installing the detection device, a power module for providing rotational power is installed inside the box, a control box for providing vacuum adsorption is fixedly connected to one end of the box away from the power module, a second rotating shaft for providing rotation is installed between the bearing seat and the control box, a fixing frame for supporting the power device is provided inside the box near the bearing seat, a fixing plate for connecting the detection device is fixedly connected to the center of the bottom of the box, and a top cover for sealing and waterproofing is fastened to the top of the box.

[0006] The beneficial effects of this utility model are: the fixed plate is fixedly connected to the center of the bottom of the box, providing a standardized installation interface for various testing components, adapting to different testing needs, and the sealed and waterproof design of the top cover can effectively block the intrusion of external rainwater and dust, protect the power module and control box and other precision components inside the box, extend the service life of the device, and enable it to adapt to complex outdoor environments.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, several sets of connecting posts are evenly distributed at the bottom of the box, and suction cups are fixed to the bottom of each connecting post. A sliding groove for moving the striking device is opened at the center of one end of the box.

[0009] Furthermore, the control box contains an electrically connected negative pressure sensor, a vacuum pump, a first lithium battery module, a first controller, and a relay. Several sets of ventilation slots are provided on both sides of the control box, and a negative pressure pipe is connected between the vacuum pump and the suction cup at the bottom of the box.

[0010] Furthermore, a third rotating shaft is installed near the top of the fixed frame. A motor is installed at one end of the third rotating shaft, and a drive wheel is fixedly connected to the end of the third rotating shaft away from the motor. The motor drives the third rotating shaft to rotate the drive wheel.

[0011] Furthermore, the power module includes a first rotating shaft, with bearing seats symmetrically fitted at both ends near the edges of the first rotating shaft. A bracket is fixed between the bottom of the bearing seats and the bottom surface inside the housing. A cam plate is fixed at the center of the outer side of the first rotating shaft. A driven wheel is fitted on the first rotating shaft at one end corresponding to the driving wheel. A belt is fitted between the driving wheel and the driven wheel.

[0012] Furthermore, support plates that are fixed to the bottom surface of the box are fitted at both ends of the second rotating shaft near the edge. A mechanical arm is fitted at the center of the outer side of the second rotating shaft. A connecting plate is fixed to the bottom of the end of the mechanical arm away from the second rotating shaft. A detection hammer is fixed to the center of the bottom of the connecting plate. A force transmission pad is fixed to the center of the bottom of the detection hammer.

[0013] Furthermore, a mounting plate is provided below the fixed plate, and several sets of spring dampers are distributed circumferentially between the fixed plate and the mounting plate. Each spring damper is fitted with a shock-absorbing spring on its outer side. A cylinder is fixedly connected to the center between the fixed plate and the mounting plate, and a piston rod is connected below the cylinder. A vibration sensor is fixedly connected to the bottom of the piston rod. A control box is fixedly connected to the bottom of the mounting plate. The control box contains a second lithium battery module, a second controller, a storage module, and an ultrasonic exchange module that are electrically connected to each other. The cylinder drives the piston rod to extend and retract the vibration sensor.

[0014] Furthermore, reflective strips are fixed around the outer edge of the top cover near the top, and heat insulation cotton is fixed inside the top cover to insulate against external heat.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: The negative pressure sensor, vacuum pump, first controller and relay integrated inside the control box form an intelligent feedback system, forming a closed-loop control logic of detection, adjustment and stabilization. The negative pressure sensor monitors the negative pressure value in the suction cup in real time and transmits the data to the first controller. When external factors cause the negative pressure to drop, the controller quickly starts the vacuum pump to replenish the pressure through the relay, ensuring that the negative pressure is always maintained at the preset threshold. When the negative pressure is too high, the controller shuts down the vacuum pump to avoid excessive adsorption that could cause local deformation of the wall surface. Attached Figure Description

[0031] Working principle: During operation, the vacuum adsorption system in the control box 2 first fixes the device to the external wall. The first lithium battery module powers the vacuum pump, negative pressure sensor, first controller, and relay in the control box 2. After the first controller issues a command, the relay starts the vacuum pump. The vacuum pump extracts the air from the suction cup 102 below the bottom connecting column 101 of the box 1 through the negative pressure pipe 201, creating a negative pressure in the suction cup 102, thus tightly adsorbing it onto the building's external wall. The negative pressure sensor monitors the negative pressure value in the suction cup 102 in real time and feeds the data back to the first controller. When the negative pressure is lower than the preset threshold, the first controller controls the vacuum pump to start again to replenish the pressure through the relay. When the negative pressure is too high, the vacuum pump stops working, thereby dynamically maintaining a stable adsorption force to ensure that the device does not fall off during the testing process. The ventilation slots 202 on both sides of the control box 2 dissipate heat for the vacuum pump, ensuring its continuous and reliable operation.

[0032] The power module 4 provides power for the striking action of the detection hammer 504. After the motor 302 on the fixed frame 3 starts, it drives the third rotating shaft 301 to rotate. The drive wheel 303 at one end of the third rotating shaft 301 rotates accordingly. The drive wheel 303 drives the driven wheel 405 on the first rotating shaft 401 to rotate through the belt 406, thereby causing the first rotating shaft 401 to rotate. The two ends of the first rotating shaft 401 are fixed inside the box 1 by the bearing seats 402 and the bracket 404. The cam plate 403 at the center of its outer side rotates together with the first rotating shaft 401. During the rotation, the cam plate 403, in cooperation with the striking device, converts the rotational motion into the up-and-down reciprocating motion of the detection hammer 504, providing power for striking the outer wall.

[0033] The two ends of the second rotating shaft 5 are fixed inside the box 1 by the support plate 501. The mechanical arm 502 at the center of its outer side can rotate with the second rotating shaft 5, thereby adjusting the striking angle and position of the detection hammer 504. When the detection hammer 504 moves under the drive of the power module 4, the detection hammer 504 at the bottom of the connecting plate 503 transmits the force evenly to the outer wall surface under the action of the force transmission pad 505, striking the wall. At the same time, the cylinder 604 below the fixed plate 6 drives the piston rod 605 to extend and retract, causing the vibration sensor 606 to contact the wall. The vibration generated after the wall is struck is captured by the vibration sensor 606, and the vibration sensor 606 converts the vibration signal into an electrical signal.

[0034] The electrical signal collected by the vibration sensor 606 is transmitted to the control box 607 at the bottom of the mounting plate 601. The second lithium battery module in the control box 607 powers the second controller, storage module and ultrasonic exchange module. The second controller receives the vibration signal and processes it. The storage module stores the processed detection data. The ultrasonic exchange module can wirelessly transmit the data to external devices for real-time viewing by staff. In addition, the spring damper 602 between the fixed plate 6 and the mounting plate 601 and the shock-absorbing spring 603 on the outside can effectively absorb the interference of the device's own vibration on the vibration sensor 606, ensuring that the collected vibration signal is accurate and reliable.
