[0017] like Figures 1 to 6As shown, the present invention relates to a real-time information monitoring device for preventing collapse of deep foundation pits, comprising a spherical shell 1, with a pressure sensor 2 fixedly sleeved inside the spherical shell 1. It is worth noting that the pressure sensor 2 is a conventional instrument of the prior art. The pressure sensor 2 is used to monitor the pressure changes of the foundation pit on the support plate in real time. The pressure sensor should have high precision, high sensitivity, and good stability, accurately measuring minute pressure changes and converting the pressure signal into an electrical signal for transmission to the monitoring system. A support mechanism 3 is provided on the outside of the spherical shell 1; the protection mechanism 3 includes a central support 301, a protection unit 4, and a fixing unit 5. The protective unit 4 is fixedly connected to the spherical shell 1, and the fixing unit 5 is fixedly connected to the protective unit 4. The middle bracket 301 is fixedly sleeved on the side surface of the spherical shell 1. Transmission brackets 302 are respectively provided at both ends of the spherical shell 1, and the two transmission brackets 302 are respectively fixedly connected to the pressure sensor 2 by the first bolt. Several first support rods 303 are provided on the side surface of the middle bracket 301, and several second support rods 304 are respectively provided on the opposite side of the two transmission brackets 302. The first support rods 303 and the second support rods 304 are movably connected to the fixing bracket 305 by the first pin. It is worth noting that the fixing bracket 305 is fixedly connected to the first support rods 303 and the second support rods 304 by the first pin. The fixed frame 305 can clamp and fix the mounting block 401. Through the movement of the first support rod 303 and the second support rod 304, the fixed frame 305 moves outward to contact the surrounding wall, providing a stable monitoring environment for the device. Gaskets 306 are fixedly connected to both sides of the spherical shell 1. Conical springs 307 are fixedly connected to the side of the two gaskets 306 away from the central support 301, and the conical springs 307 are fixedly connected to the transmission support 302. It is worth noting that the conical springs 307 prevent the transmission support 302 from affecting the use of the pressure sensor 2 due to its own weight. Furthermore, the conical springs 307... The compression capacity of 07 ensures that when the transmission bracket 302 applies force to the pressure sensor 2, it is not affected by the thickness of the conical spring 307 during compression. By setting up the protective unit 4, the protective airbag 404 can be deployed in time to protect the monitoring device in the event of a deep foundation pit collapse, thereby improving the service life of the monitoring device. At the same time, the support mechanism 3 provides the triggering condition for the airbag while supporting the device. In addition, during installation, the device is fixed by contacting the inner wall of the hole with the hook 506, which helps to improve the service life of the device and reduce the cost of real-time monitoring of collapse prevention.

[0018] In an embodiment of the present invention, a plurality of first hinge frames 301a are provided on the side surface of the central support 301, and a first support rod 303 is movably connected to the inner walls on both sides of the first hinge frame 301a via a second pin. A plurality of second hinge frames 302a are respectively provided on the side surfaces of the two transmission supports 302, and the second hinge frames 302a correspond in position to the first hinge frames 301a. A second support rod 304 is movably connected to the inner walls on both sides of the second hinge frame 302a via a third pin. In another embodiment of the present invention, the protective unit 4 includes several mounting blocks 401, which are respectively fixedly connected inside the fixing frame 305. Two mounting blocks 401 are respectively fixedly connected to metal plates 402 on opposite sides. It is worth noting that the metal plates 402 themselves have elastic deformation characteristics. In use, the metal plates 402 move inside the movable box 403 by moving the fixing frame 305. When the metal plates 402 move a certain distance inside the movable box 403, the protective airbags 404 inside them pop out from inside the movable box 403 to protect the spherical shell 1 and the pressure sensor 2. The other two mounting blocks 401 are respectively fixedly connected to the movable boxes 403 on both sides, and the metal plates 402 are inserted into the movable boxes 403. Each movable box 403 is fixedly connected to a protective airbag 404. In the event of a deep foundation pit collapse, the spherical shell 1... The transmission brackets 302 on both sides are subjected to external pressure and squeezed towards the spherical shell 1. This causes the first support rod 303 and the second support rod 304 to move synchronously, causing the mounting block 401 to move outward. During this process, the movement of the mounting block 401 causes the metal plate 402 to move outward from inside the movable box 403. When the metal plate 402 moves a certain distance, the protective airbags 404 on both sides of the spherical shell 1 pop outward to protect the surface of the spherical shell 1, enabling the pressure sensor 2 to be used multiple times and improving the service life of the device. By setting the metal plate 402, when the two transmission brackets 302 are subjected to external force, the fixed frame 305 can be driven to move outward, causing the metal plate 402 to move out of the movable box 403, realizing the pop-out of the protective airbags 404, protecting the detection device, and improving the protective effect of the device.

[0019] In another embodiment of the present invention, the fixing unit 5 includes two insert cylinders 501, which are respectively fixedly connected to the two transmission brackets 302 on the side away from the central bracket 301. Limiting frames 502 are respectively fixedly sleeved inside the two insert cylinders 501. A transmission rod 503 is movably adjusted on the inner wall of the limiting frame 502. A fixing cylinder 504 is slidably connected inside each insert cylinder 501. It is worth noting that the fixing cylinder 504 and the insert cylinder 501 are slidably connected via a slide rail and a slide groove. In its non-rotating working state, the two fixed cylinders 504 have several strip-shaped grooves 505 on their side surfaces, arranged in a circular array. Each strip-shaped groove 505 has a hook 506 movably connected to its inner walls via a first insert rod, and the groove 505 and hook 506 are compatible. A first spring 507 is fixedly connected between the groove 505 and the hook 506. A transmission button 503a is fixedly sleeved at one end of the transmission rod 503, and a threaded cylinder 503b is fixedly connected to the other end of the transmission rod 503. The threaded cylinder 503b and the fixed cylinder 504 are threadedly matched. In complex geological conditions, a hole is first drilled in the wall using an external drilling device. Then, the insertion cylinder 501 is aligned with the hole, and the transmission knob 503a is rotated using other tools, causing the transmission rod 503 to drive the threaded cylinder 503b to rotate. Since the threaded cylinder 503b and the fixed cylinder 504 are threadedly matched, and the fixed cylinder 504 is limited inside the insertion cylinder 501, the fixed cylinder 504 moves out of the insertion cylinder 501, and the end with the hook 506 contacts the inner wall of the hole. At this time, the first spring 507 applies a force to the hook 506, ensuring that the hook 506 is always in contact with the inner wall of the hole, thereby achieving the overall fixing function of the device. This invention achieves the fixing effect of the monitoring device by having the hook 506 contact the inner wall of the hole. Furthermore, during a collapse, the fixed cylinder 504 is subjected to external force, allowing it to directly exert force on the pressure sensor 2, achieving real-time information monitoring and improving the reliability of the device.

[0020] Working Principle: This embodiment provides a real-time information monitoring device for preventing collapse in deep foundation pits. When used in complex geological conditions, a hole is first drilled in the wall using an external drilling device. Then, the insertion cylinder 501 is aligned with the hole. Next, the transmission knob 503a is rotated using other tools, causing the transmission rod 503 to drive the threaded cylinder 503b to rotate. Since the threaded cylinder 503b is threadedly matched with the fixed cylinder 504, and the fixed cylinder 504 is limited inside the insertion cylinder 501, the fixed cylinder 504 moves out of the insertion cylinder 501, bringing the end with the hook 506 into contact with the inner wall of the hole. At this time, the first spring 507 applies a force to the hook 506, causing the hook 506 to... The device remains in constant contact with the inner wall of the hole, thus achieving overall fixation. During a deep foundation pit collapse, the transmission supports 302 on both sides of the spherical shell 1 are subjected to external pressure and squeezed towards the spherical shell 1. This causes the first support rod 303 and the second support rod 304 to move synchronously, causing the mounting block 401 to move outward. During this process, the movement of the mounting block 401 causes the metal plate 402 to move outward from inside the movable box 403. When the metal plate 402 moves a certain distance, the protective airbags 404 on both sides of the spherical shell 1 pop outward to protect the surface of the spherical shell 1, enabling the pressure sensor 2 to be used multiple times and improving the service life of the device.

[0021] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
