Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an online real-time safety monitoring device for foundation pits. Background Technology

[0002] In the process of rapid urbanization, various large-scale construction projects are emerging one after another. Whether it is a towering skyscraper, a complex and huge underground utility tunnel, or a busy and orderly subway transportation hub, the construction of these projects cannot be separated from a crucial basic link: the foundation pit project. As the foundation of the entire construction project, the construction quality and safety of the foundation pit project are directly related to whether the subsequent project can be carried out smoothly, as well as the stability and safety of the building during use.

[0003] The existing monitoring devices require manual redeployment for each monitoring session. This manual redeployment involves moving, installing, and debugging the equipment, as well as completing the final preparations. This process is quite cumbersome and takes a lot of time. As a result, completing a deployment may take several hours or even longer, which prevents the monitoring work from being carried out in a timely manner.

[0004] Therefore, there is an urgent need to provide an online real-time safety monitoring device for foundation pits to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an online real-time safety monitoring device for foundation pits.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution: an online safety real-time monitoring device for foundation pits, including a connecting pipe, an installation ring fixedly connected to the bottom of the outer wall of the connecting pipe, a rotating component installed on the inner wall of the connecting pipe, a detector fixedly connected to the top of the rotating component, and a protective component installed on the top of one side of the outer wall of the connecting pipe.

[0007] The present invention is further configured such that: the rotating assembly includes a fixed rod fixedly connected to the bottom of the detector, a connecting plate fixedly connected to the bottom of the fixed rod, a limiting component fixedly connected to the inner wall of the connecting tube, a rotating rod rotatably connected to the bottom of the connecting plate, a driven gear fixedly connected to the outer wall of the rotating rod, an installation plate fixedly connected to the inner wall of the connecting tube, a motor installed at the bottom of the installation plate, and a driving gear fixedly connected to the output end of the motor.

[0008] The above technical solution involves first starting the motor, which drives the drive gear to rotate. The drive gear then drives the driven gear, which in turn drives the rotating rod to rotate synchronously. Simultaneously, the rotating rod also drives the connecting plate to rotate synchronously along the inner wall of the limiting component. Subsequently, the connecting plate drives the fixed rod to rotate synchronously, and as the fixed rod rotates, it also drives the detector to rotate synchronously, thereby achieving the purpose of rotation.

[0009] The present invention is further configured such that: the inner wall of the limiting member is provided with a rotating groove, and the bottom and top of the connecting plate are closely fitted with the corresponding surfaces of the rotating groove.

[0010] The above technical solution makes the connection between the connecting plate and the limiting component more stable during rotation. When the motor drives the driving gear, which in turn drives the driven gear and the rotating rod to rotate, a certain torque and vibration will be generated. By tightly fitting the connecting plate with the rotating groove, the shaking and offset caused by these forces can be effectively reduced, ensuring the stability of the entire rotating assembly during operation and avoiding the normal operation of the detector due to loose connection.

[0011] The present invention is further configured such that the driving gear meshes with the driven gear, and the driving gear and the driven gear are on the same plane.

[0012] The above technical solution ensures efficient and stable power transmission between the two gears. The motor drives the active gear to rotate, and the torque generated can be directly and smoothly transmitted to the driven gear, reducing power loss during the transmission process.

[0013] The present invention is further configured such that: the protective component includes a mounting plate fixedly connected to one side of the outer wall of the connecting pipe, an mounting pipe fixedly connected to the top of the inner wall of the mounting plate, a hydraulic cylinder mounted on the top of the mounting pipe, a protective pipe fixedly connected to the output end of the hydraulic cylinder, a plurality of limiting blocks fixedly connected to the outer wall of the protective pipe, and a plurality of limiting grooves opened on the inner walls of both the mounting pipe and the connecting pipe.

[0014] With the above technical solution, when the equipment needs to be used, the hydraulic cylinder is first started, which drives the protective tube to move upward. At the same time, multiple limit blocks will also move synchronously along the inner wall of the corresponding limit groove until the entire detector is exposed. After the test is completed, the hydraulic cylinder is started again, which drives the protective tube to move downward until the multiple limit blocks move to the bottom of the limit groove.

[0015] The present invention is further configured such that: the mounting plate is an integral structure with the connecting pipe and the mounting plate, and the mounting plate, the connecting pipe and the mounting plate are all made of high carbon steel.

[0016] Through the above technical solution, when the torque, vibration and other forces generated by the detector during rotation are transmitted to the mounting plate and connecting pipe, the integrated high-carbon steel structure can evenly distribute and bear these forces, ensuring the stability and reliability of the entire device during operation and reducing monitoring errors or equipment failures caused by structural damage.

[0017] The present invention is further configured such that: each of the plurality of limiting blocks is matched with a corresponding limiting groove, and each pair of limiting blocks is set at a 90° angle.

[0018] The above technical solution enables precise constraint of components in multiple directions. In the foundation pit monitoring device, this multi-angle limiting method can accurately position components such as detectors in both horizontal and vertical directions, ensuring that they are in the optimal monitoring position and angle, thereby improving the accuracy and reliability of monitoring data.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up a rotating component, this utility model eliminates the need to frequently travel between different detection points to rearrange the equipment. At the same time, the direction and angle of the detector can be adjusted simply by rotating the component, which greatly reduces manpower input.

[0021] 2. By setting up protective components, this utility model can block the corrosion of the outer shell and internal materials of the device by factors such as ultraviolet rays, oxygen, and moisture, thereby slowing down the aging rate of the materials. At the same time, it can also reduce the wear of internal parts of the device, reduce the failure rate, and facilitate disassembly and installation, making it convenient for maintenance personnel to conduct regular inspections and maintenance of the device, thus improving management efficiency.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 5A real-time online safety monitoring device for foundation pits includes a connecting pipe 1, with an installation ring 2 fixedly connected to the bottom of the outer wall of the connecting pipe 1, and a rotating assembly 3 installed on the inner wall of the connecting pipe 1. The rotating assembly 3 includes a fixed rod 301 fixedly connected to the bottom of a detector 4, a connecting plate 302 fixedly connected to the bottom of the fixed rod 301, a limit member 303 fixedly connected to the inner wall of the connecting pipe 1, a rotating rod 304 rotatably connected to the bottom of the connecting plate 302, a driven gear 305 fixedly connected to the outer wall of the rotating rod 304, and an installation plate 306 fixedly connected to the inner wall of the connecting pipe 1. A motor 307 is mounted on the bottom of the mounting plate 306, and a drive gear 308 is fixedly connected to the output end of the motor 307. First, the motor 307 is started, causing it to drive the drive gear 308 to rotate. Then, the drive gear 308 drives the driven gear 305, which in turn drives the rotating rod 304 to rotate synchronously. Simultaneously, the rotating rod 304 also drives the connecting plate 302 to rotate synchronously along the inner wall of the limiting member 303. Subsequently, the connecting plate 302 drives the fixed rod 301 to rotate synchronously. While the fixed rod 301 rotates, it also drives the detector 4 to rotate synchronously, thereby achieving the purpose of rotation. The inner wall of the limiting member 303 is provided with a rotating groove, and the bottom and top of the connecting plate 302 are tightly fitted with the corresponding surfaces of the rotating groove. This makes the connection between the connecting plate 302 and the limiting member 303 more stable during rotation. When the motor 307 drives the drive gear 308, which in turn drives the driven gear 305 and the rotating rod 304 to rotate, a certain torque and vibration will be generated. The tight fit between the connecting plate 302 and the rotating groove can effectively reduce the shaking and offset caused by these forces, ensuring the stability of the entire rotating assembly 3 during operation and preventing the detector 4 from being affected by loose connections. The drive gear 308 meshes with the driven gear 305, and the drive gear 308 and the driven gear 305 are on the same plane. This ensures that the power is transmitted efficiently and stably between the two gears. The torque generated by the motor 307 driving the drive gear 308 to rotate can be directly and smoothly transmitted to the driven gear 305, reducing the loss in the power transmission process.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a detector 4 is fixedly connected to the top of the rotating assembly 3. A protective assembly 5 is installed on the top of one side of the outer wall of the connecting pipe 1. The protective assembly 5 includes a mounting plate 501 fixedly connected to one side of the outer wall of the connecting pipe 1. A mounting pipe 502 is fixedly connected to the top of the inner wall of the mounting plate 501. A hydraulic cylinder 503 is installed on the top of the mounting pipe 502. A protective pipe 504 is fixedly connected to the output end of the hydraulic cylinder 503. Multiple limit blocks 505 are fixedly connected to the outer wall of the protective pipe 504. Multiple limit grooves 506 are opened on the inner walls of both the mounting pipe 502 and the connecting pipe 1. When the equipment needs to be used, the hydraulic cylinder 503 is first started, so that the hydraulic cylinder 503 drives the protective pipe 504 to move upward. At the same time, the multiple limit blocks 505 will also move synchronously along the inner wall of the corresponding limit grooves 506 until the detector 4 is fully exposed. After the detection is completed, the hydraulic cylinder 503 is started again, so that the hydraulic cylinder 503 drives the protective pipe 504 to move downward until the multiple limit blocks 505 move downward. The device can be moved to the bottom of the limiting groove 506. The mounting plate 501 is an integral structure with the connecting pipe 1 and the mounting plate 501. The mounting plate 501, the connecting pipe 1 and the mounting plate 501 are all made of high carbon steel. When the torque, vibration and other forces generated by the detector 4 during rotation are transmitted to the mounting plate 501 and the connecting pipe 1, the integral high carbon steel structure can evenly distribute and bear these forces, ensuring the stability and reliability of the entire device during operation, and reducing monitoring errors or equipment failures caused by structural damage. Multiple limiting blocks 505 are matched with corresponding limiting grooves 506, and every two limiting blocks 505 are set at a 90° angle. This can accurately constrain the components in multiple directions. In the foundation pit monitoring device, this multi-angle limiting method can accurately position the detector 4 and other components in both horizontal and vertical directions, ensuring that they are in the optimal monitoring position and angle, thereby improving the accuracy and reliability of the monitoring data.

[0031] In use, when the equipment is needed, the hydraulic cylinder 503 is first activated, causing the protective tube 504 to move upward. At the same time, multiple limit blocks 505 move synchronously along the inner wall of the corresponding limit groove 506 until the detector 4 is fully exposed. Then, the motor 307 is activated, causing the drive gear 308 to rotate. Subsequently, the drive gear 308 drives the driven gear 305, which in turn drives the rotating rod 304 to rotate synchronously. Simultaneously, the rotating rod 304 also drives the connecting plate 302 to rotate synchronously along the inner wall of the limit member 303. Then, the connecting plate 302 drives the fixing rod 301 to rotate synchronously. While the fixing rod 301 rotates, it also drives the detector 4 to rotate synchronously, thereby achieving the purpose of rotation detection. After the monitoring is completed, the hydraulic cylinder 503 is activated again, causing the protective tube 504 to move downward until the multiple limit blocks 505 move to the bottom of the limit groove 506.
