Description

Technical Field

[0001] This utility model relates to the technical field of concrete structures, and in particular to a displacement monitoring device for concrete structures. Background Technology

[0002] Displacement monitoring devices commonly used in concrete structures are capable of real-time monitoring of displacement changes in the horizontal or vertical directions. They convert displacement signals into measurable and processable electrical or digital signals and transmit the data to an acquisition system for analysis and processing. This allows engineers to assess the safety, stability, and durability of the structure based on this data, promptly identify potential safety risks, and take necessary maintenance measures.

[0003] Existing displacement sensors mainly include displacement sensors, surveying instruments, GNSS displacement monitoring stations, tilt displacement monitoring instruments, multi-point displacement gauges, and various other displacement gauges (such as wire displacement gauges, steel wire displacement gauges, and differential resistance displacement gauges). During their use, displacement sensors typically utilize physical effects such as inductance, capacitance, and resistance to sense changes in displacement. For example, when a concrete structure undergoes displacement, the physical parameters inside the sensing element (such as inductance and capacitance values) change. This change is captured by the signal processing circuit and converted into a corresponding electrical signal. After further processing and analysis, key parameters such as the displacement amount and displacement velocity of the concrete structure can be obtained.

[0004] However, these devices often need to operate for extended periods in harsh environments. Without necessary maintenance and inspection, the equipment is prone to malfunction or performance degradation. For example, sensors may be damaged or malfunction due to environmental factors such as dust and humidity, leading to inaccurate or interrupted data acquisition. Overall maintenance requires the user to completely disassemble the device before it can be retrieved for maintenance. After maintenance, it needs to be reinstalled, making the entire process cumbersome and complex. Therefore, this application provides a displacement monitoring device for concrete structures to meet this need. Utility Model Content

[0005] The purpose of this application is to provide a displacement monitoring device for concrete structures, which solves the problem that the entire structure needs to be disassembled before maintenance in the prior art, thereby simplifying the maintenance process.

[0006] To achieve the above objectives, this application provides the following technical solution: a displacement monitoring device for concrete structures, comprising a detection body, a receiving cavity formed in the side wall of the detection body, and an insertion slot formed inside the receiving cavity, into which a mounting plate is inserted, and the mounting plate is disposed inside the receiving cavity, a first magnetic suction plate is fixedly connected inside the receiving cavity, and a first magnetic suction element is fixedly connected to the side wall of the mounting plate, the first magnetic suction plate and the first magnetic suction element are adapted to each other, and the first magnetic suction plate and the first magnetic suction element are used to limit the position of the mounting plate, and a displacement sensor is disposed inside the mounting plate.

[0007] Preferably, a compression spring is fixedly connected inside the mounting plate, and a clamping member is fixedly connected to the free end of the compression spring. The two clamping members are used to clamp the displacement sensor.

[0008] Preferably, both the clamping member and the displacement sensor are fixedly connected to the sidewalls of the clamping member and the displacement sensor, and the sidewalls of the clamping member are provided with grooves and concave-convex grooves, with two adjacent grooves and concave-convex grooves being compatible.

[0009] Preferably, two silicone pads are fixedly connected inside the insertion slot, and an insertion part is provided at the bottom of the mounting plate, the insertion part being located between the two silicone pads.

[0010] Preferably, the cavity has an internal mounting groove, and two electric push rods are fixedly connected inside the mounting groove. The free ends of the two electric push rods are provided with the same side baffle, and the side baffle is located on one side of the mounting plate.

[0011] Preferably, the top of the testing body is provided with a U-shaped groove, and a guide plate is fixedly connected inside the U-shaped groove. A guide member is slidably connected to the side wall of the guide plate, and a sealing cover is fixedly connected to the top of the guide member. The sealing cover is used to seal the testing body.

[0012] Preferably, a level is fixedly installed on the outside of the testing body, and a mounting bracket is fixedly connected to the side wall of the testing body.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model has a reasonable structure. By setting up a plug-in mounting plate, during long-term use, the mounting plate can be directly pulled, so that the mounting plate is subjected to force and the force is transmitted to the first magnetic suction component. When the pulling force on the first magnetic suction component is greater than the magnetic attraction force between the first magnetic plate and the first magnetic suction component, the first magnetic plate and the first magnetic suction component will separate under the action of the pulling force, so that the mounting plate loses its fixed connection structure. The mounting plate can then be directly pulled, so that the mounting plate is pulled out along the plug-in slot, thereby completing the disassembly steps of the mounting plate and the displacement sensor. Then, the displacement sensor can be directly maintained, making the maintenance of the displacement sensor more convenient.

[0015] 2. In this utility model, by setting up clamping components, before use, the clamping components can be pulled directly, causing the clamping components to be subjected to force and transmitting the force to the compression spring. This causes the compression spring to deform and shorten, thereby increasing the distance between the two clamping components. This allows different types of displacement sensors to autonomously enter between the two clamping components. Upon release, the clamping components will autonomously reset under the action of the deformation reaction force of the compression spring. This ensures that the two clamping components can quickly clamp the displacement sensor from both sides, keeping the displacement sensor stable during use, and effectively clamping and limiting different types of displacement sensors.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0028] The following is combined Figure 1-4 The embodiments shown illustrate the technical solution of this utility model:

[0029] The device includes a detection body 1, a receiving cavity 2 on the side wall of the detection body 1, and an insertion groove 3 inside the receiving cavity 2. A mounting plate 4 is inserted into the insertion groove 3 and is located inside the receiving cavity 2. A first magnetic suction plate 5 is fixedly connected inside the receiving cavity 2, and a first magnetic suction element 6 is fixedly connected to the side wall of the mounting plate 4. The first magnetic suction plate 5 and the first magnetic suction element 6 are compatible and are used to limit the position of the mounting plate 4. A displacement sensor 7 is provided inside the mounting plate 4.

[0030] During its use, the detection body 1 can be placed in a suitable position, and the displacement sensor 7 can be used to detect it directly, thus ensuring the stability of its overall use. When used for a long time, the mounting plate 4 can be pulled directly, so that the mounting plate 4 is subjected to force and the force is transmitted to the first magnetic suction member 6. When the pulling force on the first magnetic suction member 6 is greater than the magnetic attraction between the first magnetic suction plate 5 and the first magnetic suction member 6, the first magnetic suction plate 5 and the first magnetic suction member 6 will separate under the action of the pulling force, so that the mounting plate 4 loses its fixed connection structure. The mounting plate 4 can then be pulled directly, so that the mounting plate 4 is pulled out along the insertion slot 3, thus completing the disassembly steps of the mounting plate 4 and the displacement sensor 7. Then the displacement sensor 7 can be maintained directly, making the maintenance of the displacement sensor 7 more convenient.

[0031] A compression spring 8 is fixedly connected inside the mounting plate 4, and a clamping member 9 is fixedly connected to the free end of the compression spring 8. The two clamping members 9 are used to clamp the displacement sensor 7.

[0032] Before use, the clamping member 9 can be pulled directly, causing it to be subjected to force and transmit that force to the compression spring 8. This causes the compression spring 8 to deform and shorten, increasing the distance between the two clamping members 9. This allows different models of displacement sensors 7 to autonomously enter between the two clamping members 9. Once released, the clamping member 9 will autonomously reset under the reaction force of the deformation of the compression spring 8. This ensures that the two clamping members 9 can quickly clamp the displacement sensor 7 from both sides, keeping the displacement sensor 7 stable during use and effectively clamping and limiting different models of displacement sensors 7.

[0033] Both the clamping member 9 and the displacement sensor 7 are fixedly connected to the side walls of the snap-fit ​​member 10, and the side walls of the snap-fit ​​member 10 are provided with grooves and convex grooves, with two adjacent grooves and convex grooves matching each other.

[0034] During the clamping of the displacement sensor 7 by the clamping member 9, the connecting snap-fit ​​10 on the clamping member 9 will move closer to the snap-fit ​​10 connected to the displacement sensor 7, so that the two snap-fit ​​10 can be engaged by their own grooves, thereby ensuring the stability of the clamping member 9 in clamping and fixing the displacement sensor 7 and avoiding the possibility of displacement or tilting during use.

[0035] The internal fixed connection of the insertion slot 3 consists of two silicone pads 11, and the bottom of the mounting plate 4 is provided with an insertion part, which is located between the two silicone pads 11.

[0036] The insertion part can effectively place the mounting plate 4 inside the accommodating cavity 2. At this time, the insertion part and the silicone pad 11 can also effectively increase the contact friction between the mounting plate 4 and the insertion groove 3, so that it remains stable during use and avoids the possibility of displacement or tilting.

[0037] The cavity 2 has an installation groove 12 inside, and two electric push rods 13 are fixedly connected inside the installation groove 12. The free ends of the two electric push rods 13 are provided with the same side baffle 14, and the side baffle 14 is located on one side of the installation plate 4.

[0038] During its use, the electric push rod 13 can be directly controlled by an external controller, so that the electric push rod 13 can effectively drive the side baffle 14 to move, so that the two side baffles 14 can move closer to each other. When the side baffle 14 moves to a suitable position, the side baffle 14 will effectively limit the position of the mounting plate 4, thereby making the mounting plate 4 more stable during use and avoiding the possibility of the mounting plate 4 shifting or falling off under the action of external force.

[0039] The top of the testing machine body 1 is provided with a spiral groove 15, and a guide plate 16 is fixedly connected inside the spiral groove 15. A guide member 17 is slidably connected to the side wall of the guide plate 16, and a sealing cover plate 18 is fixedly connected to the top of the guide member 17. The sealing cover plate 18 is used to seal the testing machine body 1.

[0040] During maintenance, the sealing cover 18 can be pulled directly, so that the sealing cover 18 can effectively transfer its pulling force to the guide 17, so that the guide 17 can effectively slide along the guide plate 16, thereby allowing direct maintenance operations to be performed on the inside of the testing machine body 1, making maintenance more convenient and ensuring its stability during use.

[0041] A level 19 is fixedly installed on the outside of the testing body 1, and a mounting bracket 20 is fixedly connected to the side wall of the testing body 1.

[0042] During its use, the testing body 1 can be quickly installed directly through the mounting bracket 20, so that the testing body 1 remains stable during use. At the same time, the setting of the level 19 during installation can also better ensure that the testing body 1 is installed horizontally, avoiding the possibility of tilting or shifting.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
