Description

Technical Field

[0001] This invention relates to the field of sensor technology, specifically to an automatic detection sensor for deformation of matrix-distributed building components. Background Technology

[0002] Building components refer to the parts that make up the various elements of a building. They play a crucial role in construction, collectively constituting the building's structure and function. For example, floors separate floors and bear and transfer loads; walls function as load-bearing structures, enclosures, and space dividers; columns support the building's weight and transfer loads to the foundation; and the foundation is the building's supporting structure, bearing the weight of the entire building. These components can be made from a variety of materials, such as concrete, steel, and wood, with appropriate materials selected based on specific design and requirements. Furthermore, building components include not only structural elements but also decorative components such as doors, windows, and decorative panels. These components not only enhance the building's functionality but also improve its aesthetics and comfort.

[0003] In building construction, rectangular building components are often used to support the building. To ensure the stability of the construction, it is necessary to detect whether the rectangular building components are deformed. Therefore, deformation detection sensors are required.

[0004] For example, a vibration displacement sensor with heat dissipation that is easy to dissipate can cool the probe by adjusting the position of the probe through the setting of the cooling sleeve. At the same time, when the sensor is not in use, the cooling sleeve can be adjusted to store the probe inside, which can protect the probe. However, the device still has certain defects.

[0005] The cooling sleeve protects the probe, but it has an opening on the left side, which prevents the probe from being completely protected. As a result, when the sensor is not in use, a lot of dust will accumulate on the surface of the probe, reducing its sensing accuracy.

[0006] Therefore, we propose an automatic detection sensor for the deformation of building components with a matrix distribution, in order to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic detection sensor for the deformation of matrix-distributed building components, in order to solve the problem mentioned in the background art that the existing displacement sensors on the market use a cooling sleeve to protect the probe, but the left side of the cooling sleeve has an opening, so the probe cannot be completely protected by the cooling sleeve. Therefore, when the sensor is not in use, a lot of dust will adhere to the surface of the probe, which will reduce the sensing accuracy of the probe.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automatic detection sensor for deformation of matrix-distributed building components, comprising a horizontal plate and a displacement sensor body, wherein the displacement sensor body is disposed above the horizontal plate, and a detection probe and a magnetic block are installed on the left side of the displacement sensor body; a fixing plate is installed above the right side of the horizontal plate, and a driving assembly is installed on the left side of the fixing plate; a connecting strip is installed above the displacement sensor body via a hinge assembly, and a protective cover is installed on the connecting strip via a connecting assembly;

[0009] A power supply assembly and a baffle assembly are installed on the top of the displacement sensor body, and a rack is installed on the right side of the baffle assembly. A positioning groove is provided on the top of the protective cover, and a sloping groove is provided below the positioning groove.

[0010] Preferably, the displacement sensor body consists of a sensitive element and a conversion element. The sensitive element can sense the position change of the measured object, while the conversion element converts the position change into an electrical signal or other form of signal output. The sensitive element senses the matrix-distributed building components through a detection probe.

[0011] Using the above structural design, the surface of the matrix-distributed building components is detected by the detection probe on the displacement sensor body. The sensitive element senses the matrix-distributed building components through the detection probe, and transmits the position change measured by the sensitive element to the conversion element. The conversion element converts the position change into an electrical signal, thereby determining whether the matrix-distributed building components have deformed.

[0012] Preferably, a groove is provided on the left side of the fixing plate, and a limiting slider is engaged inside the groove. The limiting slider is fixed to the right side of the displacement sensor body, and a sliding connection structure is formed between the limiting slider and the groove.

[0013] With the above structural design, when the position of the displacement sensor body is finely adjusted, the displacement sensor body can move up and down along the slide groove through the limiting slider, thus making the displacement sensor body more stable when moving up and down.

[0014] Preferably, the drive assembly includes a connecting plate, a servo motor, a transmission shaft, and a gear mechanism. The connecting plate is mounted on the left side of the fixed plate, and the servo motor is mounted on the rear side of the connecting plate. The transmission shaft is mounted on the front side of the servo motor via an output shaft, and a gear mechanism is mounted on the transmission shaft. The servo motor is a self-locking type motor.

[0015] With the above structural design, when the servo motor drives the transmission shaft to rotate, the transmission shaft can drive the gear mechanism to rotate. When the servo motor is turned off, the position of the servo motor will not change.

[0016] Preferably, the gear mechanism meshes with the rack, and the gear mechanism is fixedly connected to the transmission shaft.

[0017] With the above structural design, the servo motor is started, and the servo motor drives the transmission shaft to rotate through the output shaft. The transmission shaft drives the gear mechanism to rotate, and the gear mechanism drives the rack to move up and down, thereby driving the baffle assembly to move up and down. This, in turn, drives the displacement sensor body connected to the baffle assembly to move up and down, thus facilitating the movement of the displacement sensor body and enabling the detection of deformation at different heights of the matrix-distributed building components.

[0018] Preferably, a handle and a counterweight are installed on the left side of the protective cover, with the counterweight located below the handle.

[0019] With the above structural design, when using the displacement sensor body, after the protective cover is opened, the protective cover is perpendicularly abutted against the baffle assembly. At the same time, under the action of the counterweight, the center of gravity of the protective cover is lowered, making the protective cover more stable. When closing the protective cover, the protective cover is rotated downward along the hinge assembly, so that the protective cover is attracted by the magnetic block on the displacement sensor body.

[0020] Preferably, the connecting assembly includes a limiting plate, a fixing sleeve, a circular groove, a telescopic spring, a movable rod, a middle block, an arc-shaped block, and a limiting ball. The limiting plate is installed below the connecting strip, and the fixing sleeve passes through both the left and right sides of the limiting plate. Circular grooves are opened on both the left and right sides below the fixing sleeve. A telescopic spring is installed inside the fixing sleeve, and a movable rod is installed on the telescopic spring. The lower end of the movable rod passes through the middle block and the arc-shaped block. Limiting balls are provided on both the left and right sides above the arc-shaped block.

[0021] The above structural design allows for the connection and disassembly of the connecting strip and protective cover via connecting components.

[0022] Preferably, the fixed sleeve has a hollow internal structure, the center line of the fixed sleeve coincides with the center line of the movable rod, and the movable rod and the fixed sleeve form a sliding connection structure.

[0023] With the above structural design, the movable rod can move up and down along the fixed sleeve when subjected to force.

[0024] Preferably, when the telescopic spring is in its free state, the limiting ball is located on the arc surface of the arc block, and the limiting ball passes through the circular groove.

[0025] With the above structural design, when installing the connecting strip and protective cover, press down on the movable rod. The movable rod moves downward, causing the middle block and the arc-shaped block to move downward, so that the arc-shaped block no longer squeezes the limiting ball. At this time, insert the fixing sleeve into the positioning groove and the inclined groove on the protective cover. At this time, the telescopic spring is in a compressed state. Then release the movable rod. Under the action of the telescopic spring's rebound force, the movable rod moves upward, causing the middle block and the arc-shaped block to move upward, so that the arc-shaped block squeezes the limiting ball. The limiting ball moves outward and engages with the fixed inclined groove on the protective cover, thereby realizing the installation of the protective cover. Similarly, pressing the movable rod completes the disassembly of the protective cover, thus facilitating the replacement of the protective cover.

[0026] Preferably, when the telescopic spring is compressed, the limiting ball is located on the side of the middle block, and the limiting ball does not completely penetrate the circular groove.

[0027] The above structural design allows the circular groove to limit the limiting ball when the telescopic spring is in its free state, preventing the limiting ball from deviating.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the deformation of the building components in this matrix distribution is automatically detected by a sensor.

[0029] 1. Equipped with a gear mechanism, the servo motor is started, and the servo motor drives the transmission shaft to rotate through the output shaft. The transmission shaft drives the gear mechanism to rotate, and the gear mechanism drives the rack to move up and down, thereby driving the baffle assembly to move up and down. This, in turn, drives the displacement sensor body connected to the baffle assembly to move up and down, thus facilitating the movement of the displacement sensor body and enabling the detection of deformation at different heights of the matrix-distributed building components.

[0030] 2. With a limit ball installed, when installing the connecting strip and protective cover, press down on the movable rod. The movable rod moves downward, causing the middle block and the arc block to move downward, so that the arc block no longer squeezes the limit ball. At this time, insert the fixing sleeve into the positioning groove and the inclined groove on the protective cover. At this time, the telescopic spring is in a compressed state. Then release the movable rod. The movable rod moves upward under the action of the telescopic spring, causing the middle block and the arc block to move upward, so that the arc block squeezes the limit ball. The limit ball moves outward and engages with the fixed inclined groove on the protective cover, thereby realizing the installation of the protective cover. Similarly, press the movable rod to complete the disassembly of the protective cover, which facilitates the replacement of the protective cover.

[0031] 3. Equipped with a counterweight, when the displacement sensor body is in use, the protective cover is opened and then vertically abuts against the baffle assembly. At the same time, the counterweight lowers the center of gravity of the protective cover, making it more stable. When closing the protective cover, it is rotated downward along the hinge assembly, causing the cover to be attracted by the magnetic block on the displacement sensor body. The protective cover protects the detection probe and reduces the coverage of dust on the detection probe. Attached Figure Description

[0043] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-10This invention provides a technical solution: an automatic detection sensor for deformation of matrix-distributed building components, comprising a horizontal plate 1, a displacement sensor body 2, a detection probe 3, a magnetic block 4, a fixing plate 5, a sliding groove 6, a limiting slider 7, a connecting plate 8, a servo motor 9, a transmission shaft 10, a gear mechanism 11, a hinge assembly 12, a connecting strip 13, a protective cover 14, a handle 15, a counterweight 16, a power supply assembly 17, a baffle assembly 18, a rack 19, a limiting plate 20, a fixing sleeve 21, a circular groove 22, a telescopic spring 23, a movable rod 24, a middle block 25, an arc-shaped block 26, a limiting ball 27, a positioning groove 28, and an inclined groove 29. The displacement sensor body 2 is disposed above the horizontal plate 1, and the detection probe 3 is installed on the left side of the displacement sensor body 2. Along with the magnetic block 4, the displacement sensor body 2 consists of a sensitive element and a conversion element. The sensitive element can sense the position change of the measured object, while the conversion element converts the position change into an electrical signal or other form of signal output. The sensitive element senses the matrix-distributed building components through the detection probe 3, and detects the surface of the matrix-distributed building components through the detection probe 3 on the displacement sensor body 2. Specifically, the sensitive element senses the matrix-distributed building components through the detection probe 3, and transmits the position change measured by the sensitive element to the conversion element. The conversion element converts the position change into an electrical signal, thereby determining whether the matrix-distributed building components have deformed. A fixing plate 5 is installed on the upper right side of the horizontal plate 1, and a sliding groove is opened on the left side of the fixing plate 5. 6. A limiting slider 7 is engaged inside the slide groove 6. The limiting slider 7 is fixed to the right side of the displacement sensor body 2. The limiting slider 7 and the slide groove 6 form a sliding connection structure. When fine-tuning the position of the displacement sensor body 2, the displacement sensor body 2 can move up and down along the slide groove 6 via the limiting slider 7, thus making the displacement sensor body 2 more stable during up and down movement. A drive assembly is installed on the left side of the fixing plate 5. The drive assembly includes a connecting plate 8, a servo motor 9, a transmission shaft 10, and a gear mechanism 11. The connecting plate 8 is installed on the left side of the fixing plate 5, and the servo motor 9 is installed on the rear side of the connecting plate 8. The transmission shaft 10 is installed on the front side of the servo motor 9 via an output shaft. The gear mechanism 11 is installed on the transmission shaft 10. The gear mechanism 11 and the gear... The racks 19 mesh with each other, and the gear mechanism 11 is fixedly connected to the transmission shaft 10. When the servo motor 9 is started, the servo motor 9 drives the transmission shaft 10 to rotate via its output shaft. The transmission shaft 10 drives the gear mechanism 11 to rotate, and the gear mechanism 11 drives the racks 19 to move up and down, thereby driving the baffle assembly 18 to move up and down. This, in turn, drives the displacement sensor body 2 connected to the baffle assembly 18 to move up and down, thus facilitating the movement of the displacement sensor body 2 and enabling the detection of deformation at different heights of the matrix-distributed building components. The servo motor 9 is a self-locking motor. When the servo motor 9 drives the transmission shaft 10 to rotate, the transmission shaft 10 can drive the gear mechanism 11 to rotate. When the servo motor 9 is turned off, its position remains unchanged.A connecting strip 13 is mounted on the top of the displacement sensor body 2 via a hinge assembly 12, and a protective cover 14 is mounted on the connecting strip 13 via a connecting assembly. A handle 15 and a counterweight 16 are mounted on the left side of the protective cover 14, with the counterweight 16 located below the handle 15. When using the displacement sensor body 2, after opening the protective cover 14, the protective cover 14 is perpendicularly pressed against the baffle assembly 18. Simultaneously, the counterweight 16 lowers the center of gravity of the protective cover 14, making it more stable. When closing the protective cover 14, it is rotated downwards along the hinge assembly 12, causing the protective cover 14 to be attracted by the magnetic block 4 on the displacement sensor body 2.

[0045] A power supply assembly 17 and a baffle assembly 18 are mounted on the top of the displacement sensor body 2. A rack 19 is mounted on the right side of the baffle assembly 18. A positioning groove 28 is formed on the top of the protective cover 14, and a beveled groove 29 is formed below the positioning groove 28. The connecting assembly includes a limiting plate 20, a fixing sleeve 21, a circular groove 22, a telescopic spring 23, a movable rod 24, a middle block 25, an arc-shaped block 26, and a limiting ball 27. A limiting plate 20 is mounted below the connecting strip 13, and a fixing sleeve 21 passes through both the left and right sides of the limiting plate 20. Circular grooves 22 are formed on both the left and right sides below the fixing sleeve 21. The fixed sleeve 21 has a telescopic spring 23 installed inside, and a movable rod 24 is installed on the telescopic spring 23. The lower end of the movable rod 24 is connected to a middle block 25 and an arc-shaped block 26. Limiting balls 27 are provided on both the left and right sides above the arc-shaped block 26. The connecting strip 13 and the protective cover 14 are connected and disassembled through a connecting assembly. The fixed sleeve 21 has a hollow internal structure design. The center line of the fixed sleeve 21 coincides with the center line of the movable rod 24, and the movable rod 24 and the fixed sleeve 21 form a sliding connection structure. When the movable rod 24 is subjected to force, it can move up and down along the fixed sleeve 21. When the spring 23 is in its free state, the limiting ball 27 is located on the arc surface of the arc block 26, and the limiting ball 27 passes through the circular groove 22. When installing the connecting strip 13 and the protective cover 14, press down on the movable rod 24. The movable rod 24 moves downward, causing the middle block 25 and the arc block 26 to move downward, so that the arc block 26 no longer squeezes the limiting ball 27. At this time, insert the fixing sleeve 21 into the positioning groove 28 and the inclined groove 29 on the protective cover 14. At this time, the spring 23 is in a compressed state. Then release the movable rod 24, and the movable rod 24 moves upward under the action of the rebound force of the spring 23. The middle block 25 and the arc-shaped block 26 move upward, causing the arc-shaped block 26 to press the limiting ball 27. The limiting ball 27 moves outward and engages with the fixed inclined groove 29 on the protective cover 14, thereby realizing the installation of the protective cover 14. Similarly, pressing the movable rod 24 completes the disassembly of the protective cover 14, making it easy to replace the protective cover 14. When the telescopic spring 23 is under pressure, the limiting ball 27 is located on the side of the middle block 25, and the limiting ball 27 does not completely penetrate the circular groove 22. When the telescopic spring 23 is in a free state, the circular groove 22 limits the limiting ball 27, so that the limiting ball 27 will not deviate.

[0046] Working principle: When using the automatic detection sensor for deformation of matrix-distributed building components, firstly, the horizontal plate 1 is placed on the workbench. After the protective cover 14 is opened, it is perpendicularly abutted against the baffle assembly 18. At the same time, under the action of the counterweight 16, the center of gravity of the protective cover 14 is lowered, making the protective cover 14 more stable. Then, the matrix-distributed building components are conveyed through the conveying mechanism and passed through the detection probe 3 on the displacement sensor body 2. The detection probe 3 detects the deformation of the surface of the matrix-distributed building components. The servo motor 9 is started, and the servo motor 9 drives the transmission shaft 10 to rotate through the output shaft. The transmission shaft 10 drives the gear mechanism 11 to rotate, and the gear mechanism 11 drives the rack 19 to move up and down, thereby driving the baffle assembly 18 to move up and down, thereby driving the displacement sensor body 2 connected to the baffle assembly 18 to move up and down, thus facilitating the movement of the displacement sensor body 2 and detecting the deformation of the matrix-distributed building components at different heights.

[0047] After the test is completed, when the protective cover 14 is closed, the protective cover 14 is rotated downward along the hinge assembly 12 so that the protective cover 14 is attracted by the magnetic block 4 on the displacement sensor body 2. The protective cover 14 protects the detection probe 3 and reduces the coverage of dust on the detection probe 3.

[0048] When installing the connecting strip 13 and the protective cover 14, press down on the movable rod 24. The movable rod 24 moves downward, causing the middle block 25 and the arc-shaped block 26 to move downward, so that the arc-shaped block 26 no longer presses against the limiting ball 27. At this time, insert the fixing sleeve 21 into the positioning groove 28 and the inclined groove 29 on the protective cover 14. At this time, the telescopic spring 23 is in a compressed state. Then release the movable rod 24. The movable rod 24 moves upward under the action of the telescopic spring 23, causing the middle block 25 and the arc-shaped block 26 to move upward, so that the arc-shaped block 26 presses against the limiting ball 27. The limiting ball 27 moves outward and engages with the fixed inclined groove 29 on the protective cover 14, thereby realizing the installation of the protective cover 14. Similarly, pressing the movable rod 24 completes the disassembly of the protective cover 14, thus facilitating the replacement of the protective cover 14. This completes a series of operations. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0049] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
