Description
Technical Field
[0001] This utility model relates to the fields of large-scale infrastructure construction and civil engineering technology, specifically to an anti-salt spray sensor arrangement structure for intelligent monitoring of large-volume concrete. Background Technology
[0002] In the fields of large-scale infrastructure construction and civil engineering, the application of mass concrete is extremely widespread. For example, in key structures such as bridges, dams, and high-rise building foundations, mass concrete constitutes the main body of these engineering structures. However, due to the large volume of mass concrete and the difficulty in dissipating internal heat, temperature cracks often occur, which in turn affect the integrity and durability of the structure. In addition, in coastal areas or areas with severe salt spray environments, concrete structures also face the problem of salt spray corrosion. Harmful substances such as chloride ions in salt spray can penetrate into the concrete, accelerate the corrosion of steel bars, and further shorten the service life of the structure.
[0003] To effectively monitor the performance changes of large-volume concrete during construction and use, especially temperature stress and salt spray erosion, intelligent monitoring technology has emerged. As the core component of the intelligent monitoring system, the arrangement and resistance to environmental interference of sensors directly affect the accuracy and reliability of monitoring data. Traditional sensor arrangement methods often have problems such as inconvenient installation, unstable fixing, and susceptibility to environmental influences. Especially in salt spray environments, the corrosion resistance and long-term stability of sensors become key factors restricting the monitoring effect. Utility Model Content

The first sliding rod position can be firmly locked by the double locking of the first nut and the second nut, ensuring the stability of sensor installation. At the same time, the sensor can be inserted and removed by sliding the first sliding rod, which greatly simplifies the disassembly and assembly process and improves construction and maintenance efficiency.
[0015] 2.

[0025] This utility model provides the following technical solution:
[0026] Example 1
[0027] Please see Figure 1-4This utility model provides a technical solution: a salt spray sensor arrangement structure for intelligent monitoring of large-volume concrete, including a fixed cylinder 1 and a sensor 2. The top of the fixed cylinder 1 is provided with an installation arrangement mechanism 3, and the bottom of the inner wall of the fixed cylinder 1 is provided with a buffer mechanism 4.
[0028] The installation and arrangement mechanism 3 includes a first slide rod 31, which is located at the top of the fixed cylinder 1. A first screw 32 is fixedly connected to the top of the first slide rod 31, and a fixed frame 33 is fixedly connected to the top of the fixed cylinder 1. A first nut 34 and a second nut 35 are threadedly connected to the surface of the first screw 32. Three insertion holes 36 are opened on the surface of the fixed cylinder 1, and slots 37 are opened on the surface of the first slide rod 31.
[0029] The top of the fixed cylinder 1 has a hole that matches the first slide rod 31, and the surface of the first slide rod 31 is penetrated and slidably connected to the hole.
[0030] The top of the fixing frame 33 has a hole, and the diameter of the hole is larger than the diameter of the screw 32. The screw 32 is located inside the hole. The first nut 34 is located below the top of the inner wall of the fixing frame 33, and the second nut 35 is located above the fixing frame 33.
[0031] The three sockets 36 are on the same vertical line. The sensor 2 is inserted into the sockets 36 and the slot 37. The sensor 2 is limited by the up and down movement of the first slide bar 31.
[0032] Example 2
[0033] Please see Figure 5 Furthermore, based on Example 1, a buffer mechanism 4 is obtained.
[0034] The buffer mechanism 4 includes a fixed ring 41, which is fixedly connected to the bottom of the fixed cylinder 1. A second slide rod 42 is slidably connected to the inner wall of the fixed ring 41. A limit ring 43 is fixedly connected to the surface of the second slide rod 42. A spring 44 is sleeved between the fixed ring 41 and the limit ring 43 on the surface of the second slide rod 42. A disc 45 is fixedly connected to the bottom end of the second slide rod 42.
[0035] The bottom of the inner wall of the fixed cylinder 1 is provided with a hole that matches the second slide rod 42, and the surface of the second slide rod 42 is penetrated and slidably connected to the hole.
[0036] One end of the spring 44 is fixedly connected to the bottom of the inner wall of the fixing ring 41, and the other end of the spring 44 is fixedly connected to the top of the limiting ring 43.
[0037] In actual operation, when this device is used, first loosen the first nut 34 and the second nut 35 on the first screw 32, which is located in the fixing frame 33. At this time, the first slide rod 31 can slide up and down along the matching hole at the top of the fixing cylinder 1. Slide the first slide rod 31 so that the slot 37 on the surface of the slide rod is coaxially aligned with the three vertically linearly distributed insertion holes 36 on the surface of the fixing cylinder 1. Then, insert one end of the sensor 2 into the insertion hole 36 of the fixing cylinder 1 and the slot 37 of the slide rod in sequence to complete the initial positioning. Tighten the first nut 34 and the second nut 35 and use the clamping force of the two nuts on the fixing frame 33 to lock the position of the first screw 32, thereby fixing the first slide rod 31 and keeping the slot 37 and the insertion hole 36 aligned. Finally, the sensor 2 is firmly limited to prevent it from shifting during concrete construction or use.
[0038] When concrete is subjected to external impact, the force first acts on the disc 45 at the bottom of the buffer mechanism 4. The disc 45 transmits the force to the second slide rod 42 fixed thereto. The second slide rod 42 slides upward along the matching hole at the bottom of the inner wall of the fixed cylinder 1, causing the limiting ring 43 on the surface of the slide rod to move upward synchronously. At this time, the limiting ring 43 compresses the spring 44 located between the bottom of the fixed ring 41 and the top of the limiting ring 43. The spring 44 absorbs the impact force through elastic deformation. After the external force disappears, the spring 44 releases its elastic potential energy, pushing the limiting ring 43, the second slide rod 42 and the disc 45 to reset, realizing the cycle of automatic reset of impact absorption, and avoiding the impact force from acting directly on the sensor 2 throughout the process.
[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
