DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0019] like Figure 1 , 2As shown in Figure 3, an automatic monitoring device for tunnel settlement deformation proposed by an embodiment of the utility model includes a device bottom plate 1, which is a horizontally placed rigid plate body, a lower left metal plate 2 is fixedly installed on the left side of the top surface of the device bottom plate 1, a lower right metal plate 3 is fixedly installed on the right side of the top surface of the device bottom plate 1, an insulating support plate 4 is fixedly provided in the middle of the top surface of the device bottom plate 1, and a metal ball 5 is supported on the top surface of the insulating support plate 4, a device cover body 6 is connected to the side cover buckle of the device bottom plate 1, an upper left metal plate 7 is fixedly provided on the left side of the inner cavity of the device cover body 6, and an upper right metal plate 8 is fixedly provided on the right side of the inner cavity of the device cover body 6, the upper left metal plate 7 is located directly above the lower left metal plate 2, and the upper right metal plate 8 is located at the lower right metal plate Directly above the metal plate 3, the upper left metal plate 7 and the upper right metal plate 8 are arranged to be tilted downward from the middle of the inner cavity to both ends of the device cover 6; a first battery 9 and a first monitor 10 are fixed to the left side of the inner cavity of the device cover 6, the positive pole of the first battery 9 is electrically connected to the upper left metal plate 7, the negative pole of the first battery 9 is electrically connected to the negative terminal interface of the first monitor 10, and the lower left metal plate 2 is electrically connected to the positive terminal interface of the first monitor 10; a second battery 11 and a second monitor 12 are fixed to the right side of the inner cavity of the device cover 6, the positive pole of the second battery 11 is electrically connected to the upper right metal plate 8, the negative pole of the second battery 11 is electrically connected to the negative terminal interface of the second monitor 12, and the lower right metal plate 3 is electrically connected to the positive terminal interface of the second monitor 12.

[0020] In this embodiment, the main body of the device is placed on the ground in the tunnel, and the bottom plate 1 of the device is parallel to the ground. At this time, the metal ball 5 is located on the top surface of the insulating support plate 4 and will not roll left and right. When the ground in the tunnel sinks, if the ground in the tunnel sinks at the left end of the main body of the device, the metal ball 5 rolls to the left end until it rolls to the left end of the lower left metal plate 2 and the upper left metal plate 7, so that the two are electrically connected. At this time, the current of the first battery 9 is connected to the positive terminal interface of the first monitor 10 through the upper left metal plate 7, the metal ball 5, and the lower left metal plate 2, and then returns to the first battery 9 through the negative terminal interface of the first monitor 10. In this process, the first monitor 10 is started to send a settlement signal; similarly, if the ground in the tunnel sinks at the right end of the main body of the device, the second monitor 12 sends a settlement signal, so that the staff can determine the direction of the settlement in the tunnel.

[0021] In this embodiment, the first monitor 10 and the second monitor 12 can be sound alarms with buzzers. When the metal ball 5 is connected to the power of the two, the two emit an alarm sound to remind the staff who are monitoring the tunnel settlement that this section of the tunnel has settled. The first monitor 10 and the second monitor 12 can also be light alarms with warning lights. When the metal ball 5 is connected to the power of the two, the two emit flashing light to remind the staff who are monitoring the tunnel settlement that this section of the tunnel has settled.

[0022] Furthermore, the corners at both ends of the device base plate 1 are threadedly connected with adjustment screws 13, and the two pairs of adjustment screws 13 are used to adjust the horizontality of the device base plate 1, the lower left metal plate 2 and the lower right metal plate 3, so that the metal ball 5 is on the top surface of the insulating support plate 4 when it has not settled.

[0023] Furthermore, a sealing ring 14 is provided at the junction between the device cover 6 and the device bottom plate 1 .

[0024] Among them, the sealing ring 14 is used to seal the junction between the device cover 6 and the device bottom plate 1 to prevent water from entering the device and causing the power supply to be mistakenly connected to the two monitors, and to prevent the four metal plates and metal balls 5 in the inner cavity of the device from rusting, so that the device can be placed in a tunnel in a humid environment for a long time to monitor settlement.

[0025] Furthermore, a circular arc groove 15 is provided in the middle of the top surface of the insulating support plate 4 , and the metal ball 5 is placed in the circular arc groove 15 .

[0026] The arc groove 15 limits the position of the metal ball 5 to prevent the metal ball 5 from rolling to the left or right when it is slightly shaken or slightly settled, thereby avoiding the two monitors from being connected by mistake.

[0027] Furthermore, rolling grooves are provided at the central axis of the top surfaces of the left lower metal plate 2 and the right lower metal plate 3. The rolling grooves facilitate the rolling of the metal ball 5, preventing the metal ball 5 from being stuck when rolling from the middle of the device bottom plate 1 to its two ends, thereby affecting the monitoring of tunnel settlement.

[0028] Furthermore, the lower left metal plate 2, the lower right metal plate 3, the upper left metal plate 7 and the upper right metal plate 8 are aluminum alloy plates or copper alloy plates, and the metal ball 5 is a copper alloy ball or a silver alloy ball, which has good conductivity and can conduct current well to ensure the sensitivity of monitoring.

[0029] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
