[0035] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1-3As shown, an embodiment of the present invention provides a deformation monitoring and alarm device for the junction of a new and old culvert. The device comprises a detection platform 10, with a barrier 20 disposed on each left and right side of the detection platform 10, the barrier 20 being higher than the detection platform 10. A detection structure is disposed in the center of the detection platform 10. The detection structure comprises a rolling element 21 and a pressure detection unit 22. The two pressure detection units 22 are located on the left and right sides of the rolling element 21, respectively. Each pressure detection unit 22 is provided with a first elastic unit 23, which is connected to the barrier 20 and is in a natural state. When the rolling element 21 rolls and comes into contact with any of the pressure detection units 22, the reading of the pressure detection unit 22 changes. A suspension structure 30 is also disposed on the barrier 20, which is used to secure the detection platform 10 at the junction of the new and old culverts. Specifically, two suspension structures 30 are provided, each with its top end hinged to the top of the new or old culvert and its bottom end hinged to the barrier 20. Under the action of the suspension structure 30 , when settlement occurs between the new culvert and the old culvert, the detection platform 10 can tilt, so that the rolling body 21 rolls under the action of its own weight and contacts the pressure detection unit 22 .

[0037] The alarm device also includes a signal processing unit 40 and an alarm unit, wherein the signal processing unit 40 is connected to the pressure detection unit 22 by signal, and the signal processing is connected to the alarm unit by signal. Specifically, the pressure detection unit 22 outputs a pressure signal to the signal processing unit 40. The pressure signal is derived from the pressure signal generated by the pressure detection unit 22 being squeezed by the rolling body 21. The inclination angle of the detection platform 10 is positively correlated with the pressure borne by the pressure detection unit 22. After receiving the pressure signal, the signal processing unit 40 processes the pressure signal and converts it into the height of the settlement. According to the processing result, the signal processing unit 40 outputs a command signal to the alarm unit, and the command signal can adjust the state of the alarm unit.

[0038] Preferably, the alarm unit includes a warning light 51 and / or an alarm bell 52. The warning light 51 is a three-color warning light. In this embodiment, the three-color warning light adjusts its state according to different command signals, emitting red, yellow, and green light to indicate different colors to the observer. The pressure detection unit 22 is a pressure sensor. The rolling element 21 is a cylinder that can roll left and right.

[0039] Furthermore, a middle box 60 is provided outside the detection platform 10, and the side walls of the middle box 60 are fixedly connected to the blocking part 20. The bottom of the detection platform 10 is higher than the bottom of the middle box 60, and an accommodation cavity is formed between the bottom of the detection platform 10 and the bottom of the middle box 60. The signal processing unit 40 is arranged in the accommodation cavity, and the alarm unit is arranged at the bottom of the middle box 60.

[0040] Furthermore, an outer box is provided outside the middle box 60. The outer box includes a left box 71, a right box 72, and a sliding guide groove 73. The left box 71 includes a set of opposite first panels 711 and a first side panel provided on one side of the first panel 711. A first upper panel is provided above the first side panel and the first panel 711. A first through hole for the suspension structure 30 to pass through is provided on the first upper panel. A transparent first lower panel is provided below the first side panel and the first panel 711. Similarly, the right box 72 includes a set of opposite second panels 712 and a second side panel provided on one side of the second panel 712. A second upper panel is provided above the second side panel and the second panel 712. A first through hole for the suspension structure 30 to pass through is provided on the second upper panel. A transparent second lower panel is provided below the second side panel and the second panel 712. The first side panel is opposite to the second side panel. The aforementioned sliding guide groove 73 is fixedly set on the edges of the two first panels 711 away from the first side edge. The two second panels 712 are slidably set in the sliding guide groove 73 away from the edges of the second side panel.

[0041] In this embodiment, the left box body 71 is fixed on the top wall of the new culvert, and the right box body 72 is set on the top wall of the old culvert. Under the action of the sliding guide groove 73, the left box body 71 and the right box body 72 can move up and down independently.

[0042] A second elastic unit 74 is further provided between the outer box body and the middle box body 60 . The second elastic unit 74 is provided between the left box body 71 and the middle box body 60 , and between the right box body 72 and the middle box body 60 .

[0043] The second elastic unit 74 is used to resist horizontal vibration to prevent the pressure detection unit 22 from making a false alarm due to vibration during monitoring.

[0044] Specifically, the second elastic unit 74 is a leaf spring fixed to the left and right housings 71 and 72. A universal ball bearing 75 is located at the highest point of the leaf spring, abutting the sidewall of the middle housing 60. During vibration, the leaf spring effectively mitigates left-right vibrations. The universal ball bearing 75 also reduces friction between the leaf spring and the middle housing 60, ensuring that the leaf spring maintains contact with the middle housing 60 to mitigate lateral vibrations while not hindering vertical sliding between the middle housing 60 and the outer housing.

[0045] Preferably, a guide groove 76 is further provided on one side of the middle box body 60 facing the left box body 71 and the right box body 72. The guide groove 76 is arranged along the vertical direction, and the universal ball bearing 75 abuts against the guide groove 76. Under the restriction of the guide groove 76, the universal ball bearing 75 can only slide along the direction of the guide groove 76 to prevent the universal ball bearing 75 from being separated from the guide groove 76.

[0046] The present application also includes a power supply structure 80, which includes a solar panel electrically connected to a battery, which is electrically connected to the signal processing unit 40 and the alarm unit. The solar panel is located outside the culvert and converts solar energy into electrical energy, which is stored in the battery. The battery continuously powers the signal processing unit 40 and the alarm unit.

[0047] Preferably, the power supply structure 80 further includes a support steering plate, and the solar panel is fixed on the support steering plate. Driven by the support steering plate, the solar panel faces the sun.

[0048] Preferably, the alarm device further includes a transmission unit 90, which is signal-connected to the signal processing unit 40. The transmission unit 90 is used to signal-connect to the cloud platform and display the results processed by the signal processing unit 40 on the cloud platform.

[0049] The aforementioned suspension structure includes an upper hinge seat, a lower hinge seat and a connection, wherein the two ends of the connecting rod are respectively hinged to the upper hinge seat or the lower hinge seat, the upper hinge seat is fixedly set on the top of the new culvert or the old culvert, and the lower hinge seat is fixedly set on the blocking part 20.

[0050] When using this application, the application is hung at the junction of the new and old culverts, where one end of the detection platform 10 is fixed to the top wall of the new culvert through a suspension structure 30, and the other end of the detection platform 10 is fixed to the top wall of the old culvert through another suspension structure 30, the left box body 71 is fixedly connected to the top wall of the new culvert, and the right box body 72 is fixedly connected to the top wall of the old culvert.

[0051] For example, if an old culvert settles, the old culvert moves downward, causing the right side of the detection platform 10 to lower. Under its own weight, the rolling element 21 rolls rightward and contacts the pressure detection unit 22. The reading of the pressure detection unit 22 changes, and a pressure signal is transmitted to the signal processing unit 40. The signal processing unit 40 controls the alarm unit to issue different instructions based on the pressure signal. As the old culvert moves downward, the right side box 72, which is fixedly connected to the old culvert, descends synchronously. Because a sliding guide groove 73 is provided between the right side box 72 and the left side box 71, the left side box 71 does not interfere with the descent of the right side box 72 when the old culvert descends.

[0052] Preferably, in the present application, the existing technology can be used to divide the sinking height into three types: safe height, warning height and alarm height, and the warning can be given by the color of the warning light 51 or the sound of the alarm bell 52.

[0053] The present application only uses one detection structure to detect the settlement of new and old culverts, and the detection structure uses a pressure detection unit 22 for detection, which effectively reduces costs.

[0054] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
