[0030] Working principle: When the equipment starts up, it first provides energy through the energy storage module 1012 inside the housing mechanism 1. The charging port at the top can pre-store the power to ensure the normal operation of each component. The energy storage module 1012 is electrically connected to the control terminal 1013. The control terminal 1013, as the core control unit, receives preset program instructions or remote control signals, and then sends action instructions to each motor, push rod and other power components to coordinate the orderly operation of each mechanism. The top of the housing mechanism 1 is sealed by the cover plate mechanism 2. The cover plate mechanism 2 is fixed to the housing mechanism 1 by the fixing bolt 2011 passing through the limiting hole 201, forming a closed space to protect the core components such as the energy storage module 1012, control terminal 1013 and partition assembly 2012 from the environmental factors such as dust and rainwater of the construction site. When the robot is in its initial folded state, each actuator retracts to its minimum volume: the unfolding push rod 2013 is in a retracted state, causing the bearing mechanism 3 to approach the shell mechanism 1; the first arm 3016 and the second arm 4 are folded together, with the second arm 4 stored in the notch of the first arm 3016; the extended legs 4012 are brought close to the second arm 4 under the retraction of the extension push rod 4011. At this time, the entire robot is compact, making it easy to transport and store. When it needs to be deployed for patrol in a construction site, the control terminal 1013 sends an extension command to the unfolding push rod 2013 to start the unfolding procedure. There are four deploying push rods 2013, which are divided into two groups and fixed to the front and rear sides of the two partition assemblies 2012 inside the housing mechanism 1. The two deploying push rods 2013 in each group are arranged opposite each other. After receiving the command, the deploying push rods 2013 extend synchronously. The bearing mechanism 3 connected to its outer side moves away from the housing mechanism 1 under the action of the thrust. There are four opposing slider assemblies 301 fixed on the outer side of the bearing mechanism 3. The slider assembly 301 is embedded in the guide groove 1011 of the guide wing plate 101 on the outer side of the housing mechanism 1. The guide groove 1011 is arranged longitudinally to provide a sliding track for the slider assembly 301. Under the thrust of the deploying push rods 2013 and the guidance of the slider assembly 301, the bearing mechanism 3 moves stably in a straight line to avoid deviation or jamming, and ensure that the two sets of bearing mechanisms 3 are symmetrically deployed to the preset position to provide stable support for the subsequent action of the support arm. When the bearing mechanism 3 is unfolded in place, the control terminal 1013 starts the servo motor A3012 on the bearing mechanism 3, which is installed at the top end of the baffle assembly 3011 on the side of the bearing mechanism 3 close to the shell mechanism 1, with its output shaft extending downward and connected to the first transmission member 3013. The side of the bearing mechanism 3 away from the shell mechanism 1 is rotationally connected to the connecting seat 3014, and the second transmission member 3015 is coaxially installed on the rear side of the connecting seat 3014. Both the first transmission member 3013 and the second transmission member 3015 are bevel gear structures and vertically meshed. When the servo motor A3012 operates, the output shaft drives the first transmission member 3013 to rotate, and through gear meshing transmission, the second transmission member 3015 rotates synchronously and drives the connecting seat 3014 to rotate. The first supporting arm 3016 fixed outside the connecting seat 3014 synchronously turns with the connecting seat 3014, realizing the angle adjustment of the first supporting arm 3016 in the horizontal direction and providing a basis for the robot to adjust the walking direction or adapt to the terrain; The side of the first supporting arm 3016 away from the connecting seat 3014 is hingedly connected to the second supporting arm 4, and the servo motor B401 is installed outside the first supporting arm 3016. Its output shaft is connected to the first supporting arm 3016 through a bearing seat and directly connected to the second supporting arm 4. When the robot needs to fold the supporting arm, the servo motor B401 operates forwardly to drive the second supporting arm 4 to swing around the hinge point towards the first supporting arm 3016, and finally embeds into the missing slot at the end of the first supporting arm 3016, completing the folding and storage of the two supporting arms and reducing the overall volume. When the supporting arm needs to be unfolded for walking, the servo motor B401 operates reversely to drive the second supporting arm 4 to rotate out of the missing slot and swing to a preset angle such as a straight line or an obtuse angle with the first supporting arm 3016, forming a complete walking support structure. The side of the second supporting arm 4 away from the first supporting arm 3016 is fixed with an extension push rod 4011, which is vertically arranged with the second supporting arm 4. The output end of the extension push rod 4011 is connected to the expansion supporting leg 4012, which is provided with a cylindrical guide rod on the side close to the second supporting arm 4. The guide rod matches the through hole on the second supporting arm 4. When the robot needs to adjust the supporting range or adapt to uneven terrain, the control terminal 1013 controls the extension push rod 4011 to extend and retract. When the extension push rod 4011 extends, it drives the expansion supporting leg 4012 to move away from the second supporting arm 4, and the guide rod slides along the through hole to ensure that the expansion supporting leg 4012 extends smoothly and increases the supporting area. When it retracts, the expansion supporting leg 4012 retracts and the guide rod resets synchronously, reducing the space occupation. The anti-skid pad outside the expansion supporting leg 4012 can enhance the friction with the ground to avoid slipping during patrol and improve the walking stability of the robot on complex ground such as soil and gravel; The top end of the cover plate mechanism 2 is fixed with a transversely arranged guide rail mechanism 5, a driving motor 501 output shaft connected with a transmission screw rod 5011 is arranged on the right side of the guide rail mechanism 5, a moving mechanism 6 slidingly connected inside the guide rail mechanism 5 is matched with the transmission screw rod 5011 through an internal screw hole, and a guide sliding block 601 on the outer side of the moving mechanism 6 slides along the inner wall of the guide rail mechanism 5; when the monitoring range needs to be adjusted, the driving motor 501 is operated to drive the transmission screw rod 5011 to rotate, and the moving mechanism 6 slides transversely along the guide rail mechanism 5 under the thread transmission and the guiding effect of the guide sliding block 601, so that the horizontal adjustment of the monitoring position is realized. A steering motor 6011 output shaft connected with a bevel gear A 6012 is arranged on the front end of the moving mechanism 6, a rotating shaft member 6013 rotatingly connected inside the bevel gear A 6012 is arranged with a bevel gear B 6014 meshing with the bevel gear A 6012 on the outer side, and a tray mechanism 7 is fixed on the top end of the rotating shaft member 6013; when the steering motor 6011 is operated, the bevel gear A 6012 drives the bevel gear B 6014 to rotate, the rotating shaft member 6013 rotates with it and drives the tray mechanism 7 to horizontally steer, so that the orientation of the monitoring unit 701 and the illuminating lamp 7011 on the outer side of the tray mechanism 7 is adjusted, 360-degree dead-angle-free monitoring and illumination coverage are realized, and the needs of the environment monitoring and light supplement of the building site night patrol are met. In addition, two clamping push rods 7012 are fixed in the transverse slot on the top end of the tray mechanism 7, and a clamping assembly 7013 is connected on the inner side of the clamping push rod 7012; when the explosion-proof tool needs to be carried, the clamping push rod 7012 is extended to drive the clamping assembly 7013 to clamp the tool; when the tool does not need to be carried, the clamping push rod 7012 is retracted to release the tool, and the multifunctionality of the robot is improved. When the patrol task is completed or the robot needs to be transferred, the control terminal 1013 starts the folding program: first, the extension push rod 4011 is retracted to drive the extension supporting leg 4012 to be retracted close to the second supporting arm 4; then, the servo motor B 401 is operated in the forward direction to fold the second supporting arm 4 into the missing slot of the first supporting arm 3016; subsequently, the servo motor A 3012 is operated in the reverse direction to drive the first supporting arm 3016 to rotate to the position close to the bearing mechanism 3 through the transmission member; finally, the unfolding push rod 2013 is retracted to pull the bearing mechanism 3 to move along the guide sliding slot 1011 to the shell mechanism 1, until all the mechanisms are reset to the initial folding state, the storage is completed, at this time, the fixed bolt 2011 ensures the close connection between the cover plate mechanism 2 and the shell mechanism 1, protects the internal components, and facilitates the rapid transfer.
