[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] The utility model provides a monitoring device for deformation of highway guardrails, the device comprising a box 11 in a square structure, Figure 1 1 is a schematic diagram of the cross-sectional structure of the box, wherein the front side plate 111, the upper side plate 112, the rear side plate 113 and the lower side plate 114 enclose an internal space. The internal space accommodates a first mounting plate 12 and a second mounting plate 13. The first mounting plate 12 and the second mounting plate 13 are perpendicular to each other, wherein the first mounting plate 12 is vertically arranged on the rear side plate 113.

[0027] The first mounting plate 12 is provided with a displacement sensor 121 , a tilt sensor 122 and an MPPT controller 123 . The displacement sensor 121 , the tilt sensor 122 and the MPPT controller 123 are all electrically connected to the energy storage power supply 14 provided on the lower side plate 114 .

[0028] Sensors are windows for sensing, acquiring and monitoring information, among which the displacement sensor 121 includes eddy current displacement sensor, laser displacement sensor, capacitive displacement sensor, inductive displacement sensor, resistive displacement sensor, magnetostrictive sensor, light displacement sensor, photoelectric displacement sensor, digital displacement sensor, and servo vibration pickup; the inclination sensor 122 includes capacitive, resonant, thermal convection and optical types.

[0029] The MPPT (Maximum Power Point Tracking) controller 123 is also called the maximum power point tracking solar charging controller. It monitors the voltage and current of the photovoltaic panel in real time, as well as external environmental conditions such as temperature and light intensity, and adjusts the output voltage and current to make the photovoltaic panel work at its optimal power point, thereby maximizing the energy collection efficiency.

[0030] A control unit 131 , a first gear 132 , a first capstan drum 133 , a second gear 134 , a second capstan drum 135 , a roller 136 and a level 137 are disposed on the second mounting plate 13 .

[0031] The control unit 131 is electrically connected to the displacement sensor 121 and the inclination sensor 122 , and the energy storage power supply 14 provides a working voltage for the control unit 131 .

[0032] The control unit 131 is used to receive the transmission data signals of the displacement sensor 121 and the tilt sensor 122, process the data signals, and transmit the processing results to the cloud server or client through the signal transmitter 1311 set on the upper side plate 112. The energy storage power supply 14 provides the signal transmitter 1311 with a working voltage, and the control unit 131 is electrically connected to the signal transmitter 1311.

[0033] Corresponding to the horizontal contact of the displacement sensor 121, the first gear 132 is coaxially arranged with the first capstan 133, the first capstan 133 matches the horizontal contact of the displacement sensor 121, and the rotation of the first capstan 133 can be monitored and sensed by the displacement sensor 121. The first gear 132 rotates in the same direction as the first capstan 133, so the first gear 132 and the first capstan 133 can be welded together or integrally formed. Among them, the radius of the first gear 132 is greater than the radius of the first capstan 133, and preferably, the radius of the first gear 132 is equal to 2 to 4 times the radius of the first capstan 133.

[0034] It is known that when the displacement sensor 121 is a contact displacement sensor, such as a stretching displacement sensor, the lead wire of the displacement sensor is wound around the outside of the first capstan 133, and the displacement is monitored by rotating and stretching the lead wire by the first capstan 133. When the displacement sensor 121 is a non-contact displacement sensor, the displacement can be determined by monitoring the rotation arc length of the first gear 132 and / or the first capstan 133.

[0035] The first gear 132 is meshed with the second gear 134, and the gear ratio (transmission ratio) between the first gear 132 and the second gear 134 is 6 to 4. The second gear 134 is coaxially arranged with the second capstan drum 135 and rotates in the same direction. The radius of the second gear 134 is smaller than the radius of the second capstan drum 135. Preferably, the radius of the second gear 134 is equal to 1 / 2 to 1 / 4 of the radius of the second capstan drum 135.

[0036] The second winch drum 135 is wound with a lead wire 138 and horizontally passes through a guide tube 1111 disposed on the front side plate 111 through a roller 136. The front end of the lead wire 138 is fixed to a guardrail at a turn of a highway or a guardrail prone to landslides ( Figure 3 ), when the highway guardrail collides or landslides, the guardrail is deformed, causing the lead wire 138 wound on the second winch drum 135 to stretch, thereby causing the first gear 132 to mesh and rotate with the second gear 134. The rotation of the first gear 132 drives the first winch drum 133 to rotate. The displacement sensor 121 detects the displacement change and transmits the data signal to the control unit 131. The deformation of the guardrail is calculated through the transmission ratio relationship. When the deformation of the guardrail is greater than the preset threshold (such as 10 cm), the control unit 131 controls the signal transmitter 1311 to transmit the monitoring data to the cloud server or client. Among them, the inclination sensor 122 is used to monitor the horizontal shaking of the box. When the guardrail is instantly greatly deformed and the box shakes, it can be detected by the inclination sensor 122 and the data signal is transmitted to the control unit 131. When the tilt angle is greater than the preset threshold (such as 10 degrees), the control unit 131 controls the signal transmitter 1311 to transmit the corresponding monitoring data to the cloud server or client.

[0037] The level meter 137 disposed on the second mounting plate 13 is used to calibrate the horizontality of the installation of the box body 11 .

[0038] A photovoltaic panel 15 and a camera 16 are arranged on the outside of the box 11. The photovoltaic panel 15 is electrically connected to the MPPT controller 123 to charge the energy storage power supply 14; the camera 16 is electrically connected to the control unit 131. When the displacement sensor 121 and / or the tilt sensor 122 detects a signal change, the control unit 131 controls the camera 16 to start working, take photos or videos, and transmit the information processed by the camera 16 to the cloud server or client through the signal transmitter 1311 in real time. When the sensor does not detect a signal change, the camera 16 is in a closed state, which can reduce energy consumption.

[0039] When the transmission ratio is set too large, the radius of the first gear 132 will increase, and the volume of the box 11 will increase, thereby increasing the manufacturing cost. In order to avoid the above situation, the present application proposes another solution, see Figure 2, which is different from the structure of the above embodiment, is that a third gear 139 is arranged between the first gear 132 and the second gear 134, and the third gear 139 is meshed with the first gear 132 and the second gear 134 for transmission respectively. Preferably, the gear number ratio (transmission ratio) of the first gear 132 and the third gear 139 is 6 to 4, and the gear number ratio (transmission ratio) of the third gear 139 and the second gear 134 is 6 to 4; similarly, multiple intermediate gears can also be arranged to achieve a suitable transmission ratio.

If the specific posture changes, the directional indication will also change accordingly.
