Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit deformation monitoring technology, and in particular to a deep foundation pit deformation monitoring device. Background Technology

[0002] Deep foundation pit engineering is a critical link in building construction, underground space development and infrastructure construction. Its stability directly affects the safety of the project. Because deep foundation pit excavation is easily affected by geological conditions, groundwater, surrounding loads and other factors, it may lead to slope displacement, support structure deformation and even collapse accidents. Therefore, real-time and accurate deformation monitoring is of great significance for early warning of risks and guidance of construction.

[0003] In existing technologies, some devices are equipped with rain covers, but they need to be opened and closed manually and cannot respond to sudden rainfall. After long-term use, dirt accumulates on the surface of the protective cover, affecting the monitoring accuracy. Therefore, we propose a deep foundation pit deformation monitoring device. Utility Model Content

[0004] This invention is a deep foundation pit deformation monitoring device proposed to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deep foundation pit deformation monitoring device includes a deformation monitor, a support mounting unit, a deformation monitoring unit, an automatic rain protection unit, and a stable ground-mounting unit.

[0007] The support mounting part is used to support and install the deformation monitor;

[0008] The deformation monitoring unit is installed inside the support installation unit and is used for deep foundation pit deformation monitoring;

[0009] The automatic rain protection unit is located on the upper side of the support mounting part and is used to protect the deformation monitor from rain. The automatic rain protection unit includes an electric push rod, which is located inside the support mounting part. The output end of the electric push rod is provided with a transparent protective cover, and an automatic cleaning component is provided on one side of the transparent protective cover.

[0010] The stable ground-seat portion is located on the lower side of the support mounting portion.

[0011] Preferably, the support mounting part includes a mounting housing, one side of which is connected to a housing cover, and the outer side of the mounting housing is provided with a plurality of oblique ventilation holes.

[0012] Preferably, the deformation monitoring unit includes an electronic controller, which is disposed inside the mounting housing. A first partition is disposed inside the mounting housing and above the electronic controller. A battery is disposed on the upper side of the first partition. A second partition is disposed above the battery. A first motor is disposed on the upper side of the second partition. A third partition is disposed on the upper side of the first motor. A mounting base is disposed at the output end of the first motor. The deformation monitor is mounted on the upper side of the mounting base. A control switch is disposed on the outer side of the mounting housing.

[0013] Preferably, the automatic cleaning component includes an electronically controlled base disposed inside the transparent protective cover. A second motor is disposed on the upper side of the electronically controlled base. A first gear is disposed on the output shaft end of the second motor. A second gear is meshed with one side of the first gear. A gear ring is meshed with one side of the second gear. A top plate is disposed on the upper side of the gear ring. A scraper is disposed on the outer side of the top plate. One side of the scraper abuts against the outer side of the transparent protective cover. Rain sensors are disposed on the upper side of several of the top plates.

[0014] Preferably, the stable grounding part includes a grounding plate, which is disposed on the lower side of the mounting housing. A plurality of fixing holes are provided on one side of the grounding plate, and fixing spikes are provided in the fixing holes. Positioning spikes are provided on the lower side of the grounding plate.

[0015] In summary, this utility model has all-weather monitoring and automated protection functions. By setting up an automatic rain protection unit, when triggered by the rain sensor, the electric push rod automatically drives the transparent protective cover to cover the deformation monitor, avoiding rainwater erosion or mirror contamination, ensuring the continuity of monitoring data. Combined with the automatic cleaning component (gear-driven scraper system) of the transparent protective cover, it can remove water droplets or mud stains attached to the cover surface in real time, further ensuring monitoring accuracy and significantly improving the reliability of the device in severe weather.

[0016] This utility model adopts a modular layered structure design. By setting up a support mounting part, it adopts an integrated design of mounting shell and partition 1, partition 2 and partition 3, and arranges components such as electronic controller, battery, motor 1 and so on in functional layers, which not only optimizes space utilization, but also facilitates maintenance and repair.

[0017] This invention enhances air circulation inside the housing by incorporating slanted ventilation holes, preventing overheating of electronic components and extending the lifespan of the equipment.

[0018] This utility model has dynamic monitoring and multi-directional adjustment capabilities. By setting up a deformation monitoring unit, which drives the mounting base to rotate via a motor, the deformation monitor can achieve multi-angle monitoring, breaking through the field of view limitations of traditional fixed monitoring. It is especially suitable for the accurate collection of deformation data in different directions of deep foundation pits, reducing the risk of monitoring blind spots.

[0019] This invention features adaptive cleaning and low-power operation. The automatic cleaning component employs a linkage structure of gear one, gear two, and gear ring, with motor two as the power source, driving the scraper to circulate and scrape along the outer wall of the transparent protective cover. This results in high cleaning efficiency and low energy consumption. The trigger-type control of the rain sensor further reduces unnecessary energy consumption and improves the battery's endurance.

[0020] This invention features high stability and adaptability to various geological conditions, including soft soil and gravel, through a combination of a stable base and a dual-stage ground spike (fixed ground spike + positioning ground spike). The fixed holes allow for adjustable ground spike depth, enhancing resistance to wind loads and vibration interference, and preventing data deviations caused by foundation displacement during monitoring.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] like Figures 1-5 As shown, a deep foundation pit deformation monitoring device includes a support installation unit 1, a deformation monitoring unit 2, an automatic rain protection unit 3, and a stable ground-mounting unit 4. These components work together to achieve automated, high-precision monitoring of deep foundation pit deformation and provide rain protection, ensuring long-term stable operation.

[0029] The support mounting part 1 includes a mounting housing 11, which is made of high-strength waterproof material such as engineering plastic or aluminum alloy. It has multiple partitions inside to support various functional modules. The housing cover 12 is connected to one side of the mounting housing 11 by a hinge, which facilitates the maintenance of internal circuits and equipment. When the housing cover 12 is closed, it has a waterproof sealing strip to prevent rainwater from seeping in. The slanted vent holes 13 are evenly distributed on the outer wall of the mounting housing 11 and are slanted to prevent rainwater from entering directly. They are used for heat dissipation and to maintain internal air circulation to prevent electronic components from overheating.

[0030] The deformation monitoring unit 2 includes an electronic controller 22, which is installed at the bottom of the mounting housing 11. The controller 22 controls the operating logic of the entire monitoring device, including data acquisition, storage, and transmission. A 4G / Wi-Fi module is optional. A partition 23, located above the electronic controller 22, separates the control area from the power supply area. The battery 24 uses a lithium battery or solar panel to provide continuous power and support long-term outdoor operation. A second partition 25, located above the battery 24, isolates the power supply area from the drive area.

[0031] Motor 26 is a servo motor or stepper motor, with its output connected to mounting base 28. It can be rotated from 0° to 360° in a controlled manner, driving deformation monitor 21 to perform multi-angle monitoring. Partition 3 27 is located above motor 26 and is used to fix the motor and reduce vibration interference. Deformation monitor 21 is a high-precision laser rangefinder or tilt sensor, installed on mounting base 28, and collects data such as foundation pit displacement and settlement in real time. Control switch 29 is located on the outside of mounting housing 11 and is used to manually start and stop the equipment or switch working modes.

[0032] 4. The automatic rain protection unit 3 includes an electric push rod 31, which is vertically fixed to the inner top of the mounting housing 11. After receiving a signal from the rain sensor 310, the electric push rod 31 automatically extends and retracts, driving the transparent protective cover 32 to rise and fall. The transparent protective cover 32 is made of high-strength acrylic or tempered glass, which does not affect optical monitoring when covering the deformation monitor 21, and at the same time prevents rainwater and dust from contaminating the lens.

[0033] The automatic cleaning component includes an electronic control base 33, which is fixed inside the transparent protective cover 32 and has a built-in control circuit. It starts the cleaning program in response to the rainfall signal. The motor 34 drives the gear 35 to rotate. Through the meshing of the gear 36 and the gear ring 37, the top plate 38 and the scraper 39 move circumferentially along the outer wall of the transparent protective cover 32 to remove water droplets or stains. The rainfall sensor 310 is installed on the top plate 38 to detect the rainfall intensity in real time and trigger the closing of the protective cover and the cleaning action.

[0034] The stabilizing base 4 includes a base plate 41, which is a circular base made of metal or composite material. It is fixed to the bottom of the mounting housing 11 by bolts. Fixing holes 42 are evenly distributed along the edge of the base plate 41 for inserting fixing spikes 43 to adapt to different soil conditions. The fixing spikes 43 are adjustable-length spiral nails that enhance wind resistance and lateral displacement resistance after being screwed into the ground. The positioning spikes 44 are vertically set on the lower surface of the base plate 41 and have a conical structure, which facilitates quick insertion into soft soil or gravel layers and provides initial positioning.

[0035] Workflow of this embodiment:

[0036] Deployment phase: Place the device at the monitoring point, press down the positioning spike 44 for initial fixation, and screw in the fixing spike 43 to the required depth;

[0037] Monitoring phase: The system is started by controlling switch 29, and motor 26 rotates deformation monitor 21 according to the set program to collect pit data and transmit it to the terminal;

[0038] Rain protection phase: After the rain sensor 310 detects rainfall, the electric push rod 31 pushes the transparent protective cover 32 to close, and at the same time the motor 34 drives the scraper 39 to clean the cover surface in a cycle until the rain stops and it resets.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
