Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides an embodiment: a safety monitoring device for bridge construction management, comprising a driving vehicle 1, a monitoring camera 10 is arranged on the top of the driving vehicle 1, a cavity 2 is opened inside the driving vehicle 1, and a translation frame 3 is penetrated inside the cavity 2;

[0023] An air pump 12 is installed on the inner side of both ends of the translation frame 3, and one end of the air pump 12 is connected to the outer side of the driving vehicle 1. An air outlet pipe 14 is installed on both sides of the top of the driving vehicle 1 below the monitoring camera 10, and the bottom end of the air outlet pipe 14 is connected to the air pump 12 through a connecting pipe 13. The top of the air outlet pipe 14 is evenly provided with air outlet holes 17.

[0024] The connecting pipe 13 is located in the inner wall of the driving vehicle 1, and the air outlet 17 faces the camera surface of the monitoring camera 10;

[0025] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when in use, the obstacle is used to block the forward movement of the driving vehicle 1, so that the translation frame 3 moves in the opposite direction, thereby realizing the compression effect of the air pump 12, so that the air outlet pipe 14 produces an upward jet, so as to achieve the jet cleaning effect on the camera surface of the monitoring camera 10, and the expansion and contraction friction of the air pump 12 is used to reduce the self-vibration effect of the spring 4 during the resetting and expansion process;

[0026] Both sides of the translation frame 3 extend to the outside of the driving vehicle 1 and are equipped with baffles 11;

[0027] The cross-sectional size of the baffle 11 is adapted to the cross-sectional size of the driving vehicle 1, and a buffer pad 15 is installed on the outer side of the baffle 11;

[0028] Specifically, Figure 1 , Figure 2 As shown, when in use, the cushion 15 is used to achieve a buffering effect and reduce collision damage to the baffle 11;

[0029] A fixed box 6 is installed inside the cavity 2, and a single chip computer 9 is arranged inside the fixed box 6. Pressure sensors 8 are installed on both sides of the fixed box 6.

[0030] Two pressure sensors 8 are provided, and the two pressure sensors 8 are symmetrically structured about the central axis of the driving vehicle 1;

[0031] Both ends of the translation frame 3 outside the pressure sensor 8 are sleeved with fixed sleeves 5, and one side of the fixed sleeve 5 close to the pressure sensor 8 is installed with an extrusion convex block 7;

[0032] The positions of the extrusion convex block 7 and the pressure sensor 8 correspond to each other on the left and right. In the initial state, the pressure sensor 8 and the extrusion convex block 7 are spaced apart from each other.

[0033] The output end of the pressure sensor 8 is electrically connected to the input end of the single chip computer 9 through a wire, and the output end of the pressure sensor 8 is electrically connected to the input end of the alarm 16;

[0034] A spring 4 is installed on the other side of the fixed sleeve 5, and one end of the spring 4 is connected to the inner wall of the cavity 2. The translation frame 3 forms a left-right sliding structure with the driving vehicle 1 through the cooperation of the cavity 2, and the sliding direction is parallel to the moving direction of the driving vehicle 1. Alarms 16 are installed on both sides of the top of the driving vehicle 1, and the shooting direction of the monitoring camera 10 is perpendicular to the moving direction of the driving vehicle 1.

[0035] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when the baffle 11 is moved during use, the extrusion protrusion 7 produces an extrusion property on the pressure sensor 8, thereby cooperating with the function of the single-chip computer 9 to facilitate the opening and closing control of the alarm 16 and the driving vehicle 1, ensuring the clearance of the forward obstacles during the position transfer of the monitoring camera 10, and playing a reminder and early warning effect.

[0036] Working principle: When the utility model is used, the driving vehicle 1 is first started to move forward, and then the driving vehicle 1 drives the monitoring camera 10 to move synchronously, so that the monitoring camera 10 moves along the bridge construction direction, so as to monitor the construction site;

[0037] Secondly, when the driving vehicle 1 encounters an obstacle while moving, the obstacle first contacts the buffer pad 15. Due to the continuous movement of the driving vehicle 1, the baffle 11 drives the translation frame 3 to move in the opposite direction, so that the spring 4 on one side of the driving vehicle 1 is extended and the spring 4 on the other side is compressed, and then the extrusion convex block 7 on one side is close to the pressure sensor 8 and squeezes the pressure sensor 8, so that the pressure sensor 8 transmits the pressure signal to the single-chip microcomputer 9. The single-chip microcomputer 9 controls the driving vehicle 1 and the alarm 16, so that the alarm 16 sounds and the driving vehicle 1 stops. Due to the function of the alarm 16, the staff on site are reminded to move the obstacle to ensure the continuous forward movement of the driving vehicle 1.

[0038] Finally, due to the effect of the obstacle, the baffle 11 on one side is driven to approach the driving vehicle 1, so that the translation frame 3 compresses the air pump 12 on one side, so that the air pump 12 can inflate the connecting pipe 13, and the air passes through the connecting pipe 13 into the interior of the air outlet pipe 14, and is exhausted to the outside through the air outlet 17, so that the gas impacts the camera surface of the surveillance camera 10 to achieve a certain cleaning effect.
