Description

Technical Field

[0001] The invention relates to the technical field of sensors, in particular to an automatic detection sensor for deformation of building components distributed in a matrix. Background Art

[0002] Building components refer to the parts that make up the various elements of a building. Building components play a vital role in construction, and together they constitute the structure and function of a building. For example, floors are used to separate floors, bear and transfer loads; walls have the functions of bearing, enclosing and dividing spaces; columns are used to support the weight of the building and transfer loads to the foundation; the foundation is the supporting structure of the building, bearing the weight of the entire building. The materials of these components can be diverse, such as concrete, steel, wood, etc., and appropriate materials are selected according to specific designs and needs. In addition, building components include not only structural elements, but also decorative components, such as doors, windows, decorative panels, etc. These components not only enhance the functionality of the building, but also improve the beauty and comfort of the building.

[0003] In the construction of buildings, rectangular distributed building components are often used to support the buildings. In order to ensure the stability of the construction, it is necessary to detect whether the rectangular distributed building components are deformed. Therefore, sensors for detecting deformation are needed.

[0004] For example, a vibration displacement sensor with application number 202122640165.3 that is easy to dissipate heat can cool the probe by adjusting the position on the subject through the cooling sleeve. At the same time, when the sensor is not in use, the cooling sleeve is adjusted to store the probe inside it, which can protect the probe. However, the device still has certain defects.

[0005] The probe is protected by the cooling cover, but the left side of the cooling cover has an opening, so the probe cannot be completely protected by the cooling cover. Therefore, when the sensor is idle, a large amount of dust will adhere to the surface of the probe, reducing the sensing accuracy of the probe.

[0006] Therefore, we propose a matrix-distributed automatic detection sensor for building component deformation in order to solve the problems raised above. Summary of the invention

[0007] The purpose of the present invention is to provide a matrix-distributed automatic detection sensor for deformation of building components, so as to solve the problem raised in the above background technology that the existing displacement sensors on the market currently have a protective effect on the probe through a cooling sleeve, but the left side of the cooling sleeve is provided with an opening, so that the probe cannot be completely protected by the cooling sleeve. Therefore, when the sensor is idle, a large amount of dust will adhere to the surface of the probe, thereby reducing the sensing accuracy of the probe.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solutions: a matrix-distributed automatic detection sensor for building component deformation, comprising a horizontal plate and a displacement sensor body, wherein the displacement sensor body is arranged 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 bar is installed above the displacement sensor body through a hinge assembly, and a protective cover is installed on the connecting bar through a connecting assembly;

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

[0011] With the above structural design, the surface of the building components distributed in the matrix is ​​detected by the detection probe on the displacement sensor body, wherein the sensitive element senses the building components distributed in the matrix through the detection probe, and the position change measured by the sensitive element is transmitted to the conversion element, and the position change is converted into an electrical signal by the conversion element, so as to determine whether the building components distributed in the matrix are deformed.

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

[0013] With the above structural design, when the position of the displacement sensor body is finely adjusted, the displacement sensor body can be moved up and down along the slide groove through the limit slider, so that the displacement sensor body is more stable when moving up and down.

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

[0019] With the above structural design, when the displacement sensor body is used, after the protective cover is opened, the protective cover just vertically abuts against the baffle assembly. At the same time, under the action of the counterweight block, the center of gravity of the protective cover is lowered to make 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 adsorbed by the magnetic block on the displacement sensor body.

[0020] Preferably, the connecting assembly includes a limit plate, a fixed sleeve, a circular groove, a telescopic spring, a movable rod, an intermediate block, an arc block and a limit ball.

[0025] When the connecting strip and the protective cover are installed by adopting the above-mentioned structural design, the movable rod is pressed downward, and the movable rod moves downward, driving the middle block and the arc block to move downward, so that the arc block no longer squeezes the limiting ball. At this time, the fixed sleeve is inserted into the positioning groove and the inclined groove on the protective cover. At this time, the telescopic spring is in a compressed state, and then the movable rod is released. The movable rod moves upward under the action of the rebound force of the telescopic spring, driving the middle block and the arc block to move upward, so that the arc block squeezes the limiting ball, and 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, the movable rod is pressed to complete the disassembly of the protective cover, thereby facilitating the replacement of the protective cover.
