Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit monitoring, and more specifically, to an automatic monitoring device for the vertical displacement of foundation pit columns. Background Technique

[0002] An automatic monitoring device for the vertical displacement of foundation pit columns is a professional device used to monitor the vertical displacement of foundation pit columns in real time and automatically. It is mainly based on high-precision measurement technology. Sensors installed near the foundation pit columns sense the displacement of the column surface, and then convert these physical signals into electrical signals for processing and analysis, and finally obtain the data of vertical displacement.

[0003] At the foundation pit construction site, there are numerous construction machinery, transport vehicles and construction workers moving around. Without protective devices, a large amount of dust generated during foundation pit construction easily adheres to displacement sensors and other monitoring components, thus affecting the measurement accuracy and greatly reducing the accuracy of monitoring data. Therefore, it is necessary to design an automatic monitoring device for the vertical displacement of foundation pit columns with an auxiliary mechanism to solve the above problems. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide an automatic monitoring device for the vertical displacement of foundation pit columns. This solution provides a physical barrier for the displacement sensor with an electrically conductive corrugated protective cover, and the displacement sensor rotates automatically by an installed electric rotating base. The friction force of the flexible long bristles on the outer wall of the displacement sensor has a cleaning effect on the displacement sensor. The dust swept off by the flexible long bristles can be adsorbed through a wide-mouth straw, automatically cleaning the dust on the surface of the displacement sensor to ensure the detection performance of the displacement sensor.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] An automatic monitoring device for the vertical displacement of foundation pit columns includes a foundation pit column. The upper end of the foundation pit column is fixedly connected with a plurality of supporting side rods, and the plurality of supporting side rods are evenly distributed. The upper ends of the plurality of supporting side rods are fixedly connected with a top circular cover. The lower end of the top circular cover is fixedly connected with an electrically conductive corrugated protective cover. The lower end of the electrically conductive corrugated protective cover is fixedly connected with a heightening and matching hollow ring. The upper end of the foundation pit column is fixedly connected with an installed electric rotating base. The upper end of the installed electric rotating base is installed with a displacement sensor. The displacement sensor is located at the middle position among the plurality of supporting side rods. The right inner wall of the heightening and matching hollow ring is installed with a cleaning component plate. One end of the cleaning component plate close to the displacement sensor is fixedly connected with a plurality of flexible long bristles. The left inner wall of the heightening and matching hollow ring is provided with a dust suction inner frame, and the inner end of the dust suction inner frame is fixedly connected with a suction pump.

[0007] Further, the output end of the suction pump is fixedly connected with a wide-mouth suction pipe, and the wide-mouth suction pipe extends to the outside of the dust suction inner frame.

[0008] Further, the wide-mouth suction pipe cooperates with the flexible long brush bristles, and a vertical chute is provided on the right inner wall of the heightening and cooperating hollow ring.

[0009] Further, an electromagnetic card hole is fixedly connected to the upper inner wall of the vertical chute, and an inner slider is slidably connected to the inner end of the vertical chute.

[0010] Further, the inner slider is connected to the cleaning component plate, and metal rods are symmetrically and fixedly connected to the upper and lower ends of the inner slider.

[0011] Further, the metal rod at the upper end is engaged with the electromagnetic card hole, and a data acquisition module and a wireless transmission module are arranged at the inner end of the displacement sensor.

[0012] Further, a remote control terminal is externally connected to the displacement sensor, and the remote control terminal is connected to the data acquisition module and the wireless transmission module.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] (1) In this solution, the electric corrugated protective cover provides a physical barrier for the displacement sensor, effectively preventing external objects on the construction site from directly hitting the displacement sensor, and at the same time resisting the influence of bad weather, playing the functions of windproof, rainproof and sun protection. At the same time, the heightening and cooperating hollow ring is surrounded outside the displacement sensor, and the extended flexible long brush bristles are closely attached to the outer wall of the displacement sensor. The displacement sensor rotates by the installed electric rotating seat, and the friction force of the flexible long brush bristles on the outer wall surface of the displacement sensor is used to clean the displacement sensor. The dust swept off by the flexible long brush bristles can be adsorbed by the wide-mouth suction pipe through the suction pump in the dust suction inner frame on its back, automatically cleaning the dust on the surface of the displacement sensor to ensure the detection performance of the displacement sensor.

[0015] (2) At the same time, the connection method between the cleaning component plate and the heightening and cooperating hollow ring is to insert the metal rod on the inner slider into the corresponding electromagnetic card hole, and the electromagnetic card hole is energized to make it magnetically connected to the metal rod.

[0025] Embodiment:

[0026] Please refer to Figures 1-3, a kind of automatic monitoring device for vertical displacement of foundation pit columns, including a foundation pit column 1. At the upper end of the foundation pit column 1, a plurality of support side rods 4 are fixedly connected. The plurality of support side rods 4 are equidistantly distributed. At the upper ends of the plurality of support side rods 4, a top circular cover 7 is fixedly connected. At the lower end of the top circular cover 7, an electric corrugated protective cover 6 is fixedly connected. At the lower end of the electric corrugated protective cover 6, a heightening and matching hollow ring 5 is fixedly connected. At the upper end of the foundation pit column 1, an installation electric swivel base 2 is fixedly connected. At the upper end of the installation electric swivel base 2, a displacement sensor 3 is installed. The displacement sensor 3 is located at the middle position among the plurality of support side rods 4. On the right inner wall of the heightening and matching hollow ring 5, a cleaning component plate 15 is installed. At one end of the cleaning component plate 15 close to the displacement sensor 3, a plurality of flexible long brush hairs 16 are fixedly connected. On the left inner wall of the heightening and matching hollow ring 5, a dust suction inner frame 8 is opened. At the inner end of the dust suction inner frame 8, a suction pump 9 is fixedly connected.

[0027] Please refer to Figures 1-4 , at the output end of the suction pump 9, a wide-mouth suction pipe 10 is fixedly connected. The wide-mouth suction pipe 10 extends to the outside of the dust suction inner frame 8. The wide-mouth suction pipe 10 cooperates with the flexible long brush hairs 16. On the right inner wall of the heightening and matching hollow ring 5, a vertical sliding groove 11 is opened. At the upper inner wall of the vertical sliding groove 11, an electromagnetic clamping hole 12 is fixedly connected. At the inner end of the vertical sliding groove 11, an inner slider 14 is slidably connected. The inner slider 14 is connected to the cleaning component plate 15. At the upper and lower ends of the inner slider 14, metal rods 13 are symmetrically fixedly connected. The metal rod 13 at the upper end is clamped with the electromagnetic clamping hole 12. Inside the displacement sensor 3, a data acquisition module and a wireless transmission module are provided. The displacement sensor 3 is externally connected to a remote control terminal. The remote control terminal is connected to the data acquisition module and the wireless transmission module.

[0028] Please refer to Figures 1-4, in this solution, the displacement sensor 3 is installed on the installation electric turntable 2, and the installation electric turntable 2 is installed on the foundation pit column 1 to be used for real-time vertical displacement of the foundation pit column 1. The data acquisition module in the displacement sensor 3 processes and analyzes the data collected in the foundation pit, and then uses the wireless transmission module to wirelessly transmit the monitoring data to the remote monitoring terminal externally connected to the displacement sensor 3, realizing the automatic monitoring and real-time data transmission of the vertical displacement of the foundation pit column, improving the accuracy and efficiency of monitoring and effectively avoiding the occurrence of personnel safety accidents. Moreover, during the detection process of the displacement sensor 3, an electrically corrugated protective cover 6 driven by a hydraulic mechanism to stretch can be arranged around the displacement sensor 3, so that the electrically corrugated protective cover 6 can enclose the displacement sensor 3 inside it when the displacement sensor 3 pauses monitoring, providing a physical barrier for the displacement sensor 3, effectively preventing external objects on the construction site from directly hitting the displacement sensor 3. The electrically corrugated protective cover 6 can isolate external foreign objects to a certain extent and at the same time resist the influence of bad weather, playing the functions of wind prevention, rain prevention and sun protection. In the environment of foundation pit construction, dust is easy to adhere to the surface of the displacement sensor 3. Therefore, when the electrically corrugated protective cover 6 stretches, the heightening and matching hollow ring 5 can be enclosed outside the displacement sensor 3, so that the flexible long bristles 16 in the extended state are in close contact with the outer wall of the displacement sensor 3, and the displacement sensor 3 rotates by itself through the installation electric turntable 2, and the flexible long bristles 16 generate a cleaning effect on the outer wall surface of the displacement sensor 3 by using the friction force on the outer wall of the displacement sensor 3. The dust swept off by the flexible long bristles 16 can be adsorbed by the suction pump 9 in the dust suction inner frame 8 on its back through the wide-mouth straw 10, automatically cleaning the dust on the surface of the displacement sensor 3 to ensure the detection performance of the displacement sensor 3. At the same time, the connection method between the cleaning component plate 15 and the heightening and matching hollow ring 5 is that the metal rod 13 on the inner slider 14 is inserted into the corresponding electromagnetic card hole 12, and the electromagnetic card hole 12 is electrified to make it magnetically connected with the metal rod 13. When the flexible long bristles 16 need to be manually replaced, only need to control the electromagnetic card hole 12 to be powered off by using an external control terminal, and the whole cleaning component plate 15 can fall out of the vertical chute 11, facilitating the quick cleaning and replacement of the flexible long bristles 16.

[0029] The above is only the preferred specific implementation mode of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present utility model.
