Description

Technical Field

[0001] The present application belongs to the technical field of foundation pit monitoring, and specifically relates to a signal transfer station for deep foundation pit support monitoring. Background Art

[0002] As a foundation project for underground structure construction, deep foundation pits are crucial for construction safety. As the depth of the foundation pit increases, the risk of collapse increases exponentially. At the same time, the anti-floating problem of underground structures becomes increasingly prominent. This is especially true in areas with densely populated buildings and near rivers. High lateral earth pressure, high soil moisture content, and frequent rainy weather further increase the risk of foundation pit collapse. Therefore, the research and application of deep foundation pit deformation monitoring technology has become particularly important. Effective monitoring can not only provide early warning of potential risks and prevent them from happening, but also significantly reduce economic costs compared to post-disaster reconstruction after collapse, achieve resource recycling, and effectively protect the lives and property of the people and construction workers.

[0003] Traditional foundation pit monitoring systems, such as the LRK Internet of Things sensor foundation pit monitoring system, although they have the advantage of high precision and can realize the automatic collection of deep horizontal displacement (inclinometer), the inclinometer also has functions such as automatic calibration, initial zeroing, and real-time wireless transmission, which can monitor the foundation pit support situation in real time. However, the LRK Internet of Things sensor foundation pit monitoring system adopts sensor direct transmission technology and is connected through a large number of signal lines, which is very cumbersome. When the sensor transmits wirelessly, due to the problems of construction site and foundation pit area, the signal transmission distance of some sensors is long, which affects the stability of signal transmission, and the port connection is relatively complicated, and data processing is troublesome, which affects the stability of monitoring and the convenience of use. The traditional monitoring system is limited by the above factors and the layout flexibility is insufficient, so further improvements can be made. Summary of the Invention

[0004] The present application provides a signal transfer station for deep foundation pit support monitoring, which has the characteristics of improving monitoring efficiency, more flexible layout, and more convenient and safe use, thereby solving the problems in the above-mentioned background technology.

[0005] In order to achieve the above application objectives, this application provides the following technical solutions:

[0006] The present application provides a signal transfer station for deep foundation pit support monitoring, which includes a box body and a mounting plate. The top surface of the mounting plate is rotatably connected to a sleeve through a rotating connecting seat. The sleeve is internally threaded with a screw. The box body is fixedly installed on the top surface of the screw. A partition is fixedly installed inside the box body. A battery is fixedly installed on the top surface of the partition. A wireless communication module and a signal receiver are fixedly installed inside the box body below the partition. A solar panel is fixedly installed on the top surface of the box body through a top frame. The input end of the wireless communication module is connected to the output end of the signal receiver. The wireless communication module, the signal receiver and the solar panel are connected to the battery. The wireless communication module includes a LoRa gateway, a Zigbee coordinator and a 4GDTU.

[0007] Furthermore, the antenna of the signal receiver extends out of the box, and the box adopts a hard plastic structure.

[0008] Furthermore, the solar panel and the battery are supporting equipment, and the solar panel is arranged at an angle.

[0009] Furthermore, an internal thread that matches the screw thread is provided inside the sleeve, and a hexagonal column is fixedly sleeved on the surface of the sleeve.

[0010] Furthermore, a mercury switch is fixedly mounted on the top surface of the partition, an alarm is fixedly mounted on one side surface of the box, and the input end of the alarm and the output end of the mercury switch are electrically connected to the battery to form a circuit.

[0011] Furthermore, a guide cylinder is fixedly mounted on the top surface of the mounting plate, a guide rod is slidably inserted into the interior of the guide cylinder, and the top surface of the guide rod is fixedly connected to the bottom surface of the box body.

[0012] Furthermore, a door is hinged on the front facade of the box body.

[0013] Furthermore, a fixing bolt is threadedly connected through the surface of the mounting plate.

[0014] Compared with the existing technology, the signal transfer station for deep foundation pit support monitoring provided by this application has the following beneficial effects:

[0015] (1) This application uses a signal receiver, a wireless communication module and a battery. The box is installed on the outside of the foundation pit. The signal receiver receives the electrical signal sent by the signal transmitter of the deep foundation pit deformation monitoring sensor, analyzes the data through the wireless communication module, and converts it into a network signal and transmits it to the monitoring main frame to complete the data transfer. Compared with the traditional direct transmission system, this application uses solar energy to generate electricity through solar panels and uses batteries for storage to complete wireless power supply and wireless data transmission, reducing the complex problems of the direct transmission system signal end and avoiding the trouble of pulling wires for power supply. It improves the flexibility of the layout and the convenience of installation and use. The signal transfer is carried out through this transfer station, which solves the problem that the traditional signal transmitter has a limited transmission distance and is difficult to send signals directly to the monitoring host, thereby improving the monitoring sensitivity and the monitoring efficiency.

[0016] (2) This application uses a box with adjustable height. The staff can use a wrench to rotate the hexagonal column, thereby driving the sleeve to rotate along the rotating connecting seat. The sleeve and the screw produce relative rotation, and a relative lift is formed between the sleeve and the screw, thereby driving the screw to rise and fall, and driving the box to rise and fall, making it easier for the box to move beyond the enclosure range, reducing signal obstruction, and also making it easier for staff to carry out inspection and maintenance, further improving the convenience of use.

[0017] (3) This application uses a mercury switch and an alarm. When the transfer station is hit by a collision, the mercury switch is activated and the alarm is triggered to alert the staff that the invention is in danger of collision damage. The staff is reminded to carry out timely maintenance to avoid a larger safety accident caused by a monitoring failure, thereby improving the safety of the application.
