The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The present invention provides a device for monitoring the deviation of a subway foundation pit. Figure 1-6 As shown, the subway foundation pit deviation monitoring device includes: a base 1 and a support plate 2 arranged on the base 1; a connecting rod 3 fixedly installed on the top of the support plate 2; a feeler rod 4 installed on one side of the connecting rod 3; a U-shaped frame 5 provided above the support plate 2, and a plurality of switch devices 6 are installed in the U-shaped frame 5, and the plurality of switch devices 6 are in sliding contact with the feeler rod 4; and a monitoring mechanism provided on the support plate 2 for monitoring the deviation of the subway foundation pit.

[0027] 2 and 3. The support plate 2 is fixed to the base 1 and the fixing plate 8 is fixed to the base 1 by the fixing bolts 9. The support plate 2 is placed on the base 1 so that the support plate 2 is located between a group of connecting plates 25 on the base 1. The I-shaped rod 26 is then used to connect the connecting plate 25 and the support plate 2, thereby quickly installing the support plate 2. After the support plate 2 is installed, the support rod 7 is synchronously contacted with the support rod of the fixing plate 8. The other I-shaped rod 26 is then inserted into the groove of the support rod 7 and the support rod to connect the support rod 7 and the fixing plate 8. After the connection is completed, the card plate on one side of the support plate 2 and the support rod 7 is rotated to contact the I-shaped rod 26. The I-beam 26 is used for limiting to ensure that the device does not move. After the base 1 is installed, the limiting cylinder 18 is slid to make the limiting cylinder 18 slide away from the leg of the mounting frame 11, thereby exposing the connecting spring 12. When the foundation pit is monitored for offset, when one side of the foundation pit moves, it will drive the fixed plate 8 to move synchronously, so that the fixed plate 8 drives the U-shaped frame 5 to move synchronously. When the U-shaped frame 5 moves, it will drive the switch device 6 to contact the touch rod 4. When the touch rod 4 contacts the switch device 6, the warning light 13 automatically flashes, thereby reminding people that the foundation pit is abnormal. The switch device 6 is driven to move by the U-shaped frame 5, so that when the foundation pit is displaced, people can know in time. At the same time, this device has a compact structure, a small size, and is easy to carry, which is conducive to frequent transfer or use in different workplaces.

[0028] In a further preferred embodiment of the present invention, the monitoring mechanism includes: a mounting bracket 11 provided above the connecting rod 3; a support rod 7 fixedly installed on the legs of the mounting bracket 11; a fixing plate 8 slidably provided at one end of the support rod 7; a plurality of fixing bolts 9 respectively threadedly installed on the fixing plate 8 and the base 1; a connecting rod 10 fixedly installed on the top of the support plate 2, a connecting spring 12 fixedly installed on the top of the connecting rod 10, and the top of the connecting spring 12 is fixedly connected to the legs of the mounting bracket 11; a plurality of warning lights 13 all installed on the top of the mounting bracket 11; a power supply mechanism provided on the mounting bracket 11 for supplying power to the warning lights 13 and the switch device 6; a positioning mechanism provided on the mounting bracket 11 and the connecting rod 10 for positioning the mounting bracket 11.

[0029] In this embodiment, when the foundation pit is displaced, the fixing plate 8 will drive the mounting frame 11 to move synchronously, thereby deforming the connecting spring 12. When the connecting spring 12 is deformed, the mounting frame 11 tilts, thereby causing the switch device 6 in the U-shaped frame 5 to contact the touch rod 4, causing the switch device 6 to start the warning light 13, thereby causing the warning light 13 to flash for warning operation. The setting of the warning light 13 is conducive to timely knowing the displacement of the foundation pit, thereby facilitating subsequent timely protection of the foundation pit and other work.

[0030] In a further preferred embodiment of the present invention, the power supply mechanism includes: a solar panel 14 fixedly mounted on the top of the mounting frame 11; a power storage device 15 mounted on the bottom of the mounting frame 11, and the power storage device 15 is electrically connected to the solar panel 14, the warning light 13 and the switch device 6.

[0031] In this embodiment, since subway stations can dig open-air foundation pits and underground foundation pits, when monitoring the offset of the open-air foundation pit, the solar panel 14 absorbs light during the day, so that the solar panel 14 converts light energy into electrical energy, and transmits the electrical energy to the power storage device 15, thereby storing electricity in the power storage device 15, so that the power storage device 15 supplies power to the warning light 13 and the switch device 6. When monitoring the offset of the underground foundation pit, the solar panel 14 can be removed, and the power storage device 15 can be replaced regularly to supply power to the warning light 13 and the switch device. Through the setting of the power supply mechanism, autonomous power supply can be achieved when monitoring the open-air foundation pit, thereby effectively reducing operating costs.

[0032] In a further preferred embodiment of the present invention, a ring frame 16 is fixedly mounted on the top of the mounting frame 11 , and a lens frame 17 is detachably mounted on the ring frame 16 , and the lens frame 17 covers the warning light 13 and the solar panel 14 .

[0033] In this embodiment, the lens frame 17 is used to focus sunlight onto the solar panel 14, reduce light reflection, increase light absorption, and improve solar energy conversion efficiency. At the same time, when the lens frame 17 needs to be cleaned or replaced, it is only necessary to remove the bolts on the annular frame 16 to remove the lens frame 17, and the loading and unloading is relatively quick. Through the design of the lens frame 17, sunlight is effectively focused onto the solar panel 14, reducing the reflection loss of light, and improving the light absorption rate and the utilization rate of solar energy.

[0034] In a further preferred embodiment of the present invention, the positioning mechanism includes: a limiting cylinder 18 slidably mounted on the connecting rod 10, and the limiting cylinder 18 is in sliding contact with the support legs of the mounting frame 11; a guide groove is opened on one side of the connecting rod 10, and a guide rod 19 is fixedly installed in the guide groove; a guide block 20 slidably mounted on the guide rod 19, and the guide block 20 is fixedly connected to the inner wall of the limiting cylinder 18.

[0035] In this embodiment, when the base 1 and the fixed plate 8 are installed, the limiting cylinder 18 limits the mounting frame 11 to ensure that the connecting spring 12 will not be deformed when the fixed plate 8 is installed, thereby ensuring that the mounting frame will not be skewed. After the fixed plate 8 is installed, the limiting cylinder 18 is slid so that the limiting cylinder 18 slides along the connecting rod 10. When the limiting cylinder 18 slides, it drives the guide block 20 to slide along the guide rod 19, thereby guiding the limiting cylinder 18 for sliding. By sliding the guide block 20 along the guide rod 19, the limiting cylinder 18 is guided for sliding, ensuring that the limiting cylinder 18 will not separate from the connecting rod 10, and it is also beneficial to the subsequent positioning operation of the limiting cylinder 18.

[0036] In a further preferred embodiment of the present invention, a connecting box 21 is fixedly installed on one side of the support leg of the mounting frame 11, a positioning block 22 is provided on the connecting box 21, a U-shaped block 23 is fixedly installed on one side of the limiting cylinder 18, the U-shaped block 23 is adapted to the positioning block 22, and a pull rod 24 is fixedly installed on one side of the positioning block 22.

[0037] In this embodiment, when positioning the limiting cylinder 18, first slide the limiting cylinder 18 so that the limiting cylinder 18 slides and contacts the support leg of the mounting frame 11, so that the U-shaped block 23 pushes the positioning block 22 to one side, and the positioning block 22 slides along one side of the U-shaped block 23. When the positioning block 22 slides to the middle notch of the U-shaped block 23, the positioning block 22 automatically pops into the U-shaped block 22 to limit the U-shaped block 23, thereby ensuring that the limiting cylinder 18 is stable. The U-shaped block is limited by the positioning block, thereby fixing the limiting cylinder, and the operation is relatively quick.

[0038] In a further preferred embodiment of the present invention, a slide rod is fixedly installed in the connection box 21, and a compression spring and a slider are sleeved on the slide rod. The two ends of the compression spring are fixedly connected to one side of the inner wall of the connection box 21 and the slider respectively.

[0039] In this embodiment, when the positioning block 22 moves, it drives the slider to slide along the slide rod, causing the compression spring to stretch. When the positioning block 22 moves to the notch of the U-shaped block 23, the compression spring contracts, thereby bouncing the positioning block 22 into the U-shaped block 23. The positioning block 22 is reset by the compression spring, thereby ensuring that it will not move in the U-shaped block 23, which is beneficial to the fixation of the limit cylinder 18.

[0040] In summary, compared with the related art, the present device has the advantages of compact structure, small size, and portability, which is conducive to frequent transfer or use in different workplaces.
