Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically a simple horizontal displacement monitoring device. Background Technology

[0002] Horizontal displacement monitoring devices can capture minute displacement changes of objects such as mountains and the ground in real time, promptly detecting signs of geological disasters such as landslides and ground subsidence. They play a crucial role in the safety monitoring of major projects such as reservoir dams, bridges, and high-rise buildings. By monitoring the deformation of these structures and preventing collapses and other safety accidents, they are widely used.

[0003] However, traditional monitoring devices have the following drawbacks:

[0004] 1. Traditional monitoring devices are complex in structure and cumbersome to operate, which increases the cost of horizontal displacement monitoring.

[0005] 2. The displacement of the mountain or the base is subtle and slow, so it is difficult for staff to monitor a monitoring point for a long time. They can only use periodic inspections, which not only makes it impossible to obtain real-time horizontal displacement data, but also incurs huge labor costs. Summary of the Invention

[0006] The purpose of this utility model is to provide a simple horizontal displacement monitoring device to solve the problems in the background art, where traditional monitoring devices have complex structures and are cumbersome to operate, making it impossible to monitor data in real time and also resulting in high labor costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A simple horizontal displacement monitoring device, comprising a measuring pin, an installation platform fixedly mounted on the top of the measuring pin, a monitoring cavity opened at the top of the installation platform, an electrically connected tilt sensor, a controller and a power module fixedly mounted on the bottom wall of the monitoring cavity, and a circular level fixedly mounted on the installation platform;

[0008] The tilt sensor is installed coaxially with the center of the probe.

[0009] Preferably, the mounting platform has a small hole on its side leading to the detection chamber.

[0010] Preferably, the side of the mounting platform is fixed with an offset warning sensor indicator strip, which completely covers the small hole.

[0011] Preferably, the control offset warning sensor indicator light strip is electrically connected to the power module and the controller, respectively.

[0012] Preferably, the upper surface of the circular level is provided with numerical scale lines.

[0013] Preferably, grooves are provided on both sides of the installation platform.

[0014] Preferably, the lower surface of the installation platform has a fixing groove adapted to the test nail.

[0015] Preferably, the side of the mounting platform is provided with a threaded hole that communicates with the fixing groove, and a fixing screw with its end abutting against the test nail is threaded into the threaded hole.

[0016] Preferably, the controller includes an AD conversion module, a control module, and a wireless communication module.

[0017] Preferably, a wireless communication module is used to enable communication between the controller and external communication devices.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This device is small in size and easy to use. When staff are on site, they can determine the degree of tilt by observing the position of the bubble in the circular level. The light strip can provide a direct warning by emitting light, which reduces the difficulty and cost of monitoring.

[0020] 2. When staff are not on site, tilt angle information can still be received through external devices, so staff do not need to stay at the monitoring point for a long time, which can reduce labor costs. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] like Figure 1-4 As shown, in which, Figures 1 to 3 Only the structural diagram of this device is given; the connection methods of electrical components are not described in detail. Figure 4 and the following Figure 5 As shown in the figure. This utility model provides a simple horizontal displacement monitoring device, including a measuring nail 1, an installation platform 2 fixedly mounted on the top of the measuring nail 1, a monitoring cavity 9 opened on the top of the installation platform 2, an inclination sensor 10, a controller 11 and a power module 12 electrically connected to each other fixedly mounted on the bottom wall of the monitoring cavity 9, and a circular level 4 fixedly mounted on the installation platform 2, which can be fixed by adhesive bonding or threaded connection;

[0031] The tilt sensor 10 is installed coaxially with the center of the probe 1.

[0032] The mounting platform 2 has a small hole 6 on its side leading to the detection chamber 9. The side of the mounting platform 2 is fixed with a deviation warning sensor indicator strip 5, which completely covers the small hole 6.

[0033] The wire can pass through the small hole 6, thereby realizing the electrical connection between the equipment in the monitoring cavity 9 and the offset warning sensor indicator strip 5.

[0034] The offset warning sensor indicator strip 5 is electrically connected to the controller 11 and the power module 12 respectively. The power module 12 is used to supply power to the offset warning sensor indicator strip 5, the tilt sensor 10 and the controller 11. The controller 11 receives the tilt angle data sent by the tilt sensor 10 and sends different control signals according to the tilt angle to control the offset warning sensor indicator strip 5 to light up and turn off.

[0035] The controller 11 includes an AD conversion module, a control module, and a wireless communication module. When the control module detects that the tilt angle information reaches the threshold, it sends a control signal to control the offset warning sensor indicator 5 to light up.

[0036] When the control module detects that the tilt angle is 0, it sends a control signal to the drive module to turn off the offset warning sensor indicator light (band 5).

[0037] The wireless communication module is used to enable communication between the controller 11 and external communication devices. After the controller 11 receives the tilt angle information collected by the tilt sensor 10, the AD conversion module converts the information from analog signal to digital signal and sends it to the external communication device held by the staff through the wireless communication module.

[0038] The upper surface of the circular level 4 has several numerical scale lines 7. After the bubble in the circular level shifts, the user can observe the distance of the shift by visually observing the numerical scale lines 7.

[0039] The mounting platform 2 has grooves 8 on both sides. The grooves 8 improve the unevenness of the circular level 4, making it easier for users to pick up the circular level 4.

[0040] The side of the mounting platform 2 is provided with a threaded hole that communicates with the fixing groove, and a fixing screw 3 with its end abutting against the measuring nail 1 is threaded into the threaded hole.

[0041] In use: Place the top of the measuring nail 1 in the fixing groove. The top of the measuring nail 1 has been frosted. The user rotates the fixing screw 3 relative to the mounting platform 2. The fixing screw 3 rotates and translates relative to the mounting platform. When the fixing screw 3 contacts the measuring nail 1, it will hold the measuring nail 1 in place, thus fixing the measuring nail to the mounting platform. Then, fix the circular level 4 on the mounting platform 2. The circular level 4 has an adjustable screw. When the device is in a horizontal state, the bubble will be in the center of the circular level 4. Because the liquid is horizontal under the action of gravity, the bubble will naturally float at the highest point of the liquid, that is, the center of the circular level 4. If the device is tilted, the bubble in the circular level 4 will also tilt. Due to the action of gravity, the liquid always remains horizontal. When tilting occurs, the bubble will move to the higher position, that is, to the side opposite to the tilt direction. This can be used to determine whether it is level.

[0042] During monitoring, the controller 11 receives tilt angle information collected by the tilt sensor 10, and after AD conversion, sends it to the external communication device held by the staff, enabling remote monitoring. When the tilt angle reaches the set threshold, the control module in the controller 11 sends a control signal to control the offset warning sensor indicator light 5 to light up. At this time, the staff present can intuitively know that the tilt angle is too large, and adjust the adjustable screw or other methods to make the bubble return to the center position, so that the device returns to a horizontal state. At this time, the control module in the controller 11 sends a control signal to control the offset warning sensor indicator light 5 to turn off.
