Description

Technical Field

[0001] This utility model relates to the field of monitoring and early warning device technology, specifically a deep foundation pit support displacement monitoring and early warning device. Background Technology

[0002] In the field of construction engineering, displacement monitoring of deep foundation pit support structures is a key link to ensure construction safety. With the acceleration of urbanization and the deepening of underground space development, the scale of deep foundation pit projects continues to expand. The complex geological conditions and rainy construction environment place higher demands on the reliability of monitoring equipment.

[0003] When using early warning devices for foundation pits, the core components such as monitoring sensors and mobile power supplies are mostly installed at the lower part of the equipment support (installing the mobile power supply at a low position can improve the stability of the device). When encountering continuous rainfall, water is easily formed around the foundation pit. The power supply box may be submerged in the water, causing short circuits and component burnout, which in turn causes the monitoring system to malfunction, making it impossible to obtain real-time displacement data of the support structure and lose the early warning function. In order to solve the above problems, the inventor proposes a deep foundation pit support displacement monitoring and early warning device. Utility Model Content

[0004] To address the problem that during periods of continuous rainfall, water can easily accumulate around the foundation pit, potentially causing short circuits in the power supply box due to immersion in the water; the purpose of this invention is to provide a deep foundation pit support displacement monitoring and early warning device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a deep foundation pit support displacement monitoring and early warning device, comprising a U-shaped support frame, a U-shaped plate fixedly connected to the top of the U-shaped support frame, an installation box fixedly connected to the side of the U-shaped plate, a control button fixedly connected to the bottom of the installation box near the center of one side, an L-shaped plate fixedly connected to the bottom of the installation box near the control button, a lifting rod slidably inserted inside the L-shaped plate near one side, a float plate fixedly connected to the bottom of the lifting rod, a touch plate fixedly connected to the top of the lifting rod, and the touch plate and the control button being at the same level, a support plate slidably connected between the inner walls of the two sides of the U-shaped support frame, a power supply box provided at the top of the support plate, support rods symmetrically fixedly connected to the top of the U-shaped plate near the center, a square plate fixedly connected between the two support rods near the top, installation plates symmetrically provided on both sides of the square plate, and a rain shelter body provided between the installation plate and the square plate.

[0006] Preferably, a double-headed electric cylinder is provided near the center inside the square plate, and the output end of the double-headed electric cylinder is fixedly connected to the mounting plate. An electric cylinder is provided at the bottom of the U-shaped plate and above the support plate, and the output end of the electric cylinder is fixedly connected to the support plate.

[0007] Preferably, the mounting box has a detachable door on the side away from the U-shaped plate, and a turntable is rotatably connected to the center of the top of the mounting box, with a monitoring and early warning body installed on the top of the turntable.

[0008] Preferably, a motor is provided at the center of the mounting box, and the output end of the motor is fixedly connected to the turntable.

[0009] Preferably, guide telescopic rods are symmetrically fixedly connected to both sides of the square plate near the center, and one end of the guide telescopic rod is fixedly connected to the mounting plate. A wire harness hole is opened on the side of the mounting box near the center.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. In this utility model, when it rains and the water level reaches a certain level, the float rises, and the lifting rod drives the touch plate to rise. When the touch plate touches the control button, the protection mechanism is automatically triggered, which causes the support plate to lift the power box, keeping the power box away from the ground and preventing the power box from being damaged by being submerged in water, thus ensuring a stable power supply. In addition, the rain shelter body can be extended to provide protection for the monitoring and early warning body and the power box below, preventing them from being eroded by rainwater and extending the service life of the equipment.

[0012] 2. In this utility model, the mobile power supply inside the power box provides power to the electrical mechanism of the equipment, avoiding the need for long wiring harnesses, effectively reducing the risk of people tripping due to messy wiring harnesses, and improving the safety of the working environment.

Mounting plates 24 are symmetrically provided on both sides of the square plate 22. Triangular blocks are symmetrically fixedly connected to the bottom of the mounting plate 24 near the center. A rain shelter body 25 is provided between the mounting plate 24 and the square plate 22. The electrical components in this application and their compatible power supply are electrically connected through wires. A suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection methods are known in the art.

[0022] A double-headed electric cylinder 23 is installed near the center inside the square plate 22, and the output end of the double-headed electric cylinder 23 is fixedly connected to the mounting plate 24.

[0023] By adopting the above technical solution, the double-headed electric cylinder 23 is activated, thereby causing the two fixedly connected mounting plates 24 to move towards each other.

[0024] An electric cylinder 13 is installed at the bottom of the U-shaped plate 2 and above the support plate 11. The output end of the electric cylinder 13 is fixedly connected to the support plate 11.

[0025] By adopting the above technical solution, the working electric cylinder 13 causes the fixedly connected support plate 11 to rise and fall, thereby driving the power supply box 12 to rise.

[0036] Working Principle: When in use, the device first rotates the fixedly connected turntable 31 via the working motor 33, which in turn rotates the monitoring and early warning body 32 to monitor the foundation pit. When it rains and the water level reaches a certain level, the float 36 rises, causing the lifting rod 35 to lift the touch plate 37. When the water level reaches the touch plate 37 and touches the control button 38, the double-headed electric cylinder 23 and the first electric cylinder 13 are activated simultaneously, causing the fixedly connected support plate 11 to lift the power box 12, thus moving the power box 12 away from the ground. At the same time, after the double-headed electric cylinder 23 is activated, the two fixedly connected mounting plates 24 move towards each other, thereby extending the two rain shelter bodies 25. This provides protection for the monitoring and early warning body 32 and the power box 12 below. The mobile power supply inside the power box 12 provides power to the motor 33 and other equipment below the turntable 31, avoiding the risk of people tripping due to long wiring harnesses.
