[0019] As Figures 1-4 Shown, a simple and convenient settlement monitoring device, including measuring tube 1 and outer tube 2, measuring tube 1 both ends are closed, and the outer tube 2 one end is open and the other end is closed, and the measuring tube 1 one end is connected with the outer tube 2, and the spring 9 is arranged between the measuring tube 1 bottom and the outer tube 2 inside bottom, and the scale 102 is arranged on the measuring tube 1 surface, and the alarm device is further arranged on the outer surface upper portion position of the outer tube 2, and the measuring tube 1 reaches the outer tube 2 bottom alarm device alarm.

[0020] The measuring tube 1 is a key component for actually measuring the settlement change, which is closed at both ends to prevent external substances from entering and affecting the measurement accuracy. The measuring tube 1 is provided with scales 102 on the surface, which are used to directly read the change of the settlement amount, so that the monitoring result is intuitive and visible. The outer tube 2 serves as a structure for protecting and supporting the measuring tube 1, and one end is open to allow the measuring tube 1 to move freely inside, and the other end is closed to ensure that the spring 9 is correctly installed and kept in a compressed state. The spring 9 is located between the bottom of the measuring tube 1 and the inner bottom of the outer tube 2, which functions to maintain the position of the measuring tube 1 without external pressure, and provides a restoring force when the roof settles or the floor heaves, allowing the measuring tube 1 to accurately reflect the change in the settlement amount.

[0021] The alarm device is provided on the outer surface of the outer tube 2 at a position above, which is used to issue an alarm when the measuring tube 1 sinks to the bottom of the outer tube 2 due to the settlement of the roof, reminding the monitoring personnel that the settlement has reached a preset dangerous value and corresponding measures need to be taken.

[0022] In use, first fix one end of the measuring tube 1 to the roof of the roadway, and the other end of the outer tube 2 is supported on the floor. When the roadway deforms and causes the roof to sink or the floor to heave, the measuring tube 1 will move downward with the movement of the roof, and in this process the spring 9 will be compressed, and the scales 102 on the measuring tube 1 will show the specific settlement amount. If the settlement amount exceeds the safety threshold, the alarm device will start to alarm the staff in time.

[0023] The whole device is simple in design and easy to operate, and is suitable for long-term monitoring of the settlement of the roof and floor in various underground engineering, especially for cost-sensitive application scenarios.

[0024] In the preferred scheme, the structure of the alarm device is that the outer wall of the outer tube 2 is provided with at least one inclined elastic sheet 7, one end of the elastic sheet 7 is connected with the outer wall of the outer tube 2, the other end is provided with a hammer 6, the outer wall of the outer tube 2 at the corresponding position of the hammer 6 is provided with an electric ring 8, a magnet 10 is provided on the upper position of the tube body of the measuring tube 1, the magnet 10 absorbs the hammer 6 to abut against the electric ring 8 to form a passage, and the buzzer 4 alarms.

[0025] The outer wall of the outer tube 2 is equipped with at least one inclined elastic piece 7, one end of which is fixed to the outer wall of the outer tube 2, and the other end is raised and equipped with a hammer 6. The outer wall of the outer tube 2 at the corresponding position of the hammer 6 is provided with a contact ring 8, which is used to contact the hammer 6 to form part of the circuit. The upper part of the measuring tube 1 is equipped with a magnet 10. When the measuring tube 1 drops to a certain position due to the settlement of the roof, the magnet 10 attracts the hammer 6, making the hammer 6 tightly contact the contact ring 8 to form a closed circuit, and the buzzer 4 starts to alarm. Once the measuring tube 1 rises back to its original position due to the recovery of the roof or human adjustment, the attraction of the magnet 10 to the hammer 6 weakens, and the hammer 6 returns to its original position under the action of the elastic piece 7, and separates from the contact ring 8, causing the circuit to be disconnected, and the buzzer 4 stops alarming. This design can effectively monitor and timely report the settlement of the roof, ensuring safety.

[0026] In use, the device is installed in a place where settlement needs to be monitored, the measuring tube 1 is fixed to the upper structure, such as the roof of the tunnel, and the outer tube 2 is fixed to the lower structure, such as the floor. As the upper structure settles, the measuring tube 1 will drop relative to the outer tube 2. When the amount of settlement reaches a critical value, the relative position of the magnet 10 on the measuring tube 1 and the hammer 6 changes, eventually causing the hammer 6 to contact the contact ring 8, closing the circuit and activating the buzzer 4, thereby sending a warning signal to alert workers that the settlement has reached the warning level.

[0027] In the preferred embodiment, the alarm device is arranged inside the protective shell 3, and the battery 5 and the buzzer 4 are arranged inside the protective shell 3.

[0028] The protective shell 3 is used to encapsulate and protect the internal components, including the battery 5 and the buzzer 4. The battery 5 provides power for the entire alarm device, ensuring that the buzzer 4 can work normally when receiving a trigger signal and emit an alarm sound. The buzzer 4 is located inside the protective shell 3 and can emit a sound when the circuit is closed, serving as a warning.

[0029] In use, the battery 5 inside the protective shell 3 provides power support. When the measuring tube 1 drops, causing the magnet 10 to attract the hammer 6 to contact the contact ring 8 to form a closed circuit, the buzzer 4 is powered on and starts to emit an alarm sound. Conversely, if the measuring tube 1 rises back to its original position, the attraction of the magnet 10 to the hammer 6 weakens, and the hammer 6 separates from the contact ring 8 under the action of the elastic piece 7, the circuit is disconnected, and the buzzer 4 stops alarming. The protective shell 3 not only protects the internal components from the external environment, but also makes the entire device more compact, easy to install and maintain.

[0030] In the preferred embodiment, the battery 5 is electrically connected to the elastic piece 7 and the buzzer 4, and the buzzer 4 is electrically connected to the contact ring 8.

[0031] The battery 5 provides power for the whole alarm system, and through the electrical connection with the elastic sheet 7 and the buzzer 4, the circuit can be closed when needed. The elastic sheet 7 is fixed on the outer wall of the outer tube 2 at one end, and is buckled at the other end and provided with the hammer 6, which cooperates with the contact ring 8 and functions as a switch. The contact ring 8 is arranged on the outer wall of the outer tube 2 and is electrically connected with the buzzer 4. When the hammer 6 contacts the contact ring 8, the circuit is closed, the buzzer 4 is powered and emits an alarm sound.

[0032] In the preferred embodiment, the top of the measuring tube 1 is provided with a first support plate 101. The bottom of the outer tube 2 is provided with a second support plate 201. The top of the measuring tube 1 is provided with the first support plate 101 to increase the connection strength and stability between the measuring tube 1 and the structure above, such as the roadway roof. The bottom of the outer tube 2 is provided with the second support plate 201 to enhance the fixing effect of the outer tube 2 and the structure below, such as the floor. The first support plate 101 and the second support plate 201 work together to increase the support distance of the whole device and improve the accuracy and reliability of the measurement.

[0033] In the preferred embodiment, the materials of the measuring tube 1 and the outer tube 2 are pvc or pe. The application preferably uses pvc material.

[0034] The above-mentioned embodiments are only preferred technical solutions of the present application, and should not be regarded as limitations of the present application. The protection scope of the present application should be based on the technical solutions recited in the claims, including equivalent replacement solutions of the technical features recited in the claims. That is, equivalent replacement improvements within this range are also within the protection scope of the present application.
