Fixing the first connecting plate 312 and the second connecting plate 314 on the surface of the foundation pit bottom 2; that is, the first support plate 322 is fixed, so that the second support plate 342 is attached to and abuts against the foundation pit wall 1 via the springs 35, the foundation pit wall 1 is supported, the telescopic members 333 do not extend and retract at this time, the first support plate 322 is supported at the first angle, and the floor area is reduced.
Illustratively, when the foundation pit wall 1 is offset, the soil at the foundation pit wall 1 pushes the second support plate 342 to move towards the first support plate 322, and when the second support plate 342 leaves above the second connecting plate 314, the soil covers the second connecting plate 314 at the same time, and as the soil amount increases, the soil pressure applied to the second connecting plate 314 gradually increases, so that the first connecting plate 312 is further fixed.
Illustratively, as the second shield 342 moves toward the first shield 322, the second latch 362 moves within the second through slot 325 until the first signal transmitter 363 contacts the first signal receiver 326, causing a signal connection and transmitting the signal into the controller. Meanwhile, the third connection plate 331 moves in the first through groove 323, so that the travel of the third connection plate 331 on the sliding plate 327 is increased; at this time, the controller controls the first motor 332 to increase the included angle between the output shaft end of the telescopic assembly 333 and the third connecting plate 331, and support the first support plate 322 at a second angle, where the first angle is smaller than the second angle, and the second angle is smaller than or equal to 45 °; and one end of the output shaft of the telescopic component 333 is controlled by the controller to extend, so that the first clamping block 335 is clamped and abutted against the top end of the vertical sliding chute 324, and the supporting strength is increased. And when the second support plate 342 moves towards the first support plate 322, the second support plate 342 and the original foundation pit wall 1 form a cavity, and the cavity can be used for containing the soil collapsed by the offset of the original foundation pit wall 1 to form a buffer area, so that the gravitational potential energy of the soil at the original foundation pit wall 1 is reduced, the support difficulty is reduced, and the support mechanism 3 is more stable.
Further, two adjacent groups of supporting mechanisms 3 can be fixedly connected, so that the whole supporting capacity of the supporting mechanisms is improved.

As illustrated by way of example in fig. 8. In the figure, C0 is the origin on the projection screen 43, and is the laser initial position of the displacement measuring instrument 42. When the body of the displacement measurer 42 moves and the laser point emitted by the body is at C1, the camera in the displacement measurer extracts the pixel information of the laser point on the projection screen 43, and calculates a vertical displacement a and a horizontal displacement b by the processor, wherein a represents the displacement of the foundation pit wall 1, and b represents the sinking amount of the foundation pit bottom 2.
Further, the positions of the first signal transmitter 363 and the first signal receiver 326 may be adjusted, and determined according to the displacement amount of the second clamping block 362, for example, when the second clamping block 362 is displaced by 1cm, that is, is in the emergency position, the first signal transmitter 363 may contact with the first signal receiver 326 to send an emergency signal to the controller, and automatically start the telescopic assembly 333 to strengthen the support, and when the displacement amount of the second clamping block 362 is less than 1cm and is in the safety position, the emergency signal is not sent, and the signal is sent to the controller through the displacement measurer 42, and the staff takes corresponding measures.
The electric power foundation pit safety monitoring system based on the Internet of things, provided by the embodiment of the invention, has the following working principle:
a plurality of groups of supporting mechanisms 3 are arranged at the junction of the foundation pit wall 1 and the foundation pit bottom 2 in a linear array; attaching the second support plate 342 to the foundation pit wall 1; the retaining plate 311 is buried in the foundation pit bottom 2. Fixing the first connecting plate 312 and the second connecting plate 314 on the surface of the foundation pit bottom 2; that is, the first support plate 322 is fixed, so that the second support plate 342 is attached to and abuts against the foundation pit wall 1 via the springs 35, the foundation pit wall 1 is supported, the telescopic members 333 do not extend and retract at this time, the first support plate 322 is supported at the first angle, and the floor area is reduced. The positions of the adjacent two fifth connecting plates 41 on the track 364 are then adjusted so that the laser beams from the two displacement measuring devices 42 are located at the origin on the projection screen 43.
When the foundation pit wall 1 deviates, the soil at the foundation pit wall 1 pushes the second support plate 342 to move towards the first support plate 322, and when the second support plate 342 leaves above the second connecting plate 314, the soil can cover the second connecting plate 314, and the soil pressure applied to the second connecting plate 314 gradually increases gradually along with the increase of the soil amount, so that the first connecting plate 312 is further fixed.
As the second shield 342 moves toward the first shield 322, the second latch 362 moves within the second slot 325 until the first signal transmitter 363 contacts the first signal receiver 326, causing a signal connection and transmitting the signal into the controller. Meanwhile, the third connection plate 331 moves in the first through groove 323, so that the travel of the third connection plate 331 on the sliding plate 327 is increased; at this time, the controller controls the first motor 332 to increase the included angle between the output shaft end of the telescopic assembly 333 and the third connecting plate 331, and support the first support plate 322 at a second angle, where the first angle is smaller than the second angle, and the second angle is smaller than or equal to 45 °; and one end of the output shaft of the telescopic component 333 is controlled by the controller to extend, so that the first clamping block 335 is clamped and abutted against the top end of the vertical sliding chute 324, and the supporting strength is increased.
And when the second support plate 342 moves to the first support plate 322, a cavity is formed between the second support plate 342 and the original foundation pit wall 1, and the cavity can be used for containing the soil collapsed by the offset of the original foundation pit wall 1 to form a buffer area, so that the gravitational potential energy of the soil at the original foundation pit wall 1 is reduced, the support difficulty is reduced, and the support mechanism 3 is more stable.
When the foundation pit bottom 2 sinks, the sinking amount can be measured through the displacement measurer 42, and data are sent to the controller for early warning, and corresponding measures are taken by staff.
Meanwhile, the controller can be remotely operated through gateway equipment, so that the purpose of remote control is achieved.
