Unlike the electrical stress monitoring method, the water level change is mainly based on the physical properties of water, such as volume change, thereby ensuring the reliability of stress monitoring.

[0017] 3. Through the setting of early warning mechanism, once the stress reaches the dangerous threshold, the stress monitoring device can issue a sound warning. The loud alarm can immediately attract the attention of on-site personnel. Even if the on-site personnel are focusing on other work tasks or are in a position where they cannot visually observe the display of the monitoring device, such as behind machinery or in a dim basement, the sound warning can effectively convey information.

When the stress on the top of the top plate 203 disappears, the pad 209 will move upward under the action of the first spring 210. When the pad 209 moves downward, it will drive the first threaded rod 208 to move downward.

The first pulley 214 and the second pulley 215 are connected by a belt. The bottom of the protective plate 205 is fixedly installed with a second toothed plate 216.When the third gear 206 rotates, the rotating third gear 206 can drive the first tooth plate 212 and the slide plate 211 inside the third sliding groove 202 to slide, and the sliding of the slide plate 211 can drive the second threaded rod 213 to move inside the threaded sleeve 217, thereby driving the threaded sleeve 217 to rotate, and the rotation of the threaded sleeve 217 can drive the first pulley 214 to rotate, and the rotation of the first pulley 214 can drive the second pulley 215 to rotate, so that the bidirectional threaded rod 204 rotates, thereby driving the protective plate 205 to move, so that the protective plate 205 can be deployed. The setting of the protective plate 205 can prevent objects from falling due to changes in the stress of the top building, and provide physical protection for the staff at the bottom to prevent the staff at the bottom from being injured by falling objects from high altitude.

The display box 312 is made of a transparent material, and a scale mark is engraved on the outside of the display box 312. The staff can judge the stress at the top by observing the water level inside the display box 312. When the stress at the top disappears, the first partition 311 moves downward, thereby driving the connecting rod 314 to move downward, and then the second partition 313 can be driven to move downward. The downward movement of the second partition 313 can squeeze the water inside the display box 312.The water inside the display box 312 re-enters the water tank 310 through the water pipe 315, and at the same time the water level inside the display box 312 will also drop, so that the staff can monitor the stress by observing the change of the water level inside the display box 312.

[0025] Reference Figure 1-Figure 10 This embodiment also proposes an automated stress monitoring method, which is applicable to the above-mentioned assembled stress monitoring device, and the steps are as follows: S1: First, the staff installs the entire device to the place where stress monitoring is required. When the top of the top plate 203 is squeezed by the stress of the top, the pad 209 moves downward, thereby squeezing the first spring 210, and at the same time driving the first threaded rod 208 to move downward; S2: As the stress changes, the third gear 206 continues to rotate, thereby driving the threaded sleeve 217 to rotate, and the rotation of the threaded sleeve 217 can drive the first pulley 214 to rotate, and the rotation of the first pulley 214 can drive the second pulley 215 to rotate, so that the bidirectional threaded rod 204 rotates, thereby driving the protective plate 205 to move, so that the protective plate 205 can be unfolded; S3: When the protection plate 205 is unfolded outward, the first partition plate 311 can move upward inside the water tank 310, so that the water inside the water tank 310 enters the display box 312 through the water pipe 315. The staff can judge the stress condition of the top by observing the water level inside the display box 312; S4: When the protection plate 205 is unfolded outward, the second tooth plate 216 can be driven to move, so that the lever 409 can be rotated, and the rotating lever 409 can rotate the blocking rod 411 and the rotating plate 410, so that the reciprocating rod 413 can slide upward, and the upward sliding of the reciprocating rod 413 can drive the piston plate 415 to slide upward, and the upward sliding of the piston plate 415 can squeeze the second spring 416; S5: When the lever 409 drives the blocking rod 411 to rotate to a certain angle, no force is generated between the lever 409 and the blocking rod 411, and the second spring 416 returns to its original state under the action of the elastic force, causing the hammer head 417 to fall downward at a high speed. The downward fall of the hammer head 417 can hammer the metal plate 418, causing the metal plate 418 to make a sound, thereby alerting the staff.

[0026] Specifically, the working process or working principle of the assembled stress monitoring device is as follows: first, when the top of the top plate 203 is squeezed by the stress of the top, the pad 209 will move downward to squeeze the first spring 210. When the stress on the top of the top plate 203 disappears, under the action of the first spring 210, the pad 209 will move upward. When the pad 209 moves downward, it will drive the first threaded rod 208 to move downward. Because the pad 209 and the top plate 203 are tightly fitted, when the pad 209 moves downward, the first threaded cylinder 207 will rotate, while the first threaded rod 208 and the pad 209 will not rotate under the action of friction. At the same time, the rotation of the first threaded cylinder 207 can drive the third gear 206 to rotate. When the third gear 206 rotates, the rotating third gear 206 can drive the first tooth plate 212 and the slide plate 211 inside the third sliding groove 202 to slide, and the sliding of the slide plate 211 can drive the second threaded rod 213 to move inside the threaded sleeve 217, thereby driving the threaded sleeve 217 to rotate, and the rotation of the threaded sleeve 217 can drive the first pulley 214 to rotate, and the rotation of the first pulley 214 can drive the second pulley 215 to rotate, thereby making the bidirectional threaded rod 204 rotate, thereby driving the protective plate 205 to move, so that the protective plate 205 can be deployed. The setting of the protective plate 205 can prevent objects from falling due to changes in stress in the top building, and provide physical protection for the staff at the bottom to prevent the staff at the bottom from being injured by falling objects from high altitude.

[0027] When the protective plate 205 moves, the second tooth plate 216 at the bottom of the protective plate 205 moves. The movement of the second tooth plate 216 can drive the first gear 301 to rotate, and the rotating first gear 301 can make the third tooth plate 303 move up and down inside the first sliding groove 302. The up and down movement of the third tooth plate 303 can drive the cross plate 304 to move up and down, thereby driving the third threaded rod 305 to move up and down. The up and down movement of the third threaded rod 305 can drive the second threaded cylinder 307 to rotate, and the rotating second threaded cylinder 307 can drive the third threaded cylinder 308 to rotate. The rotating third threaded cylinder 308 can make the fourth threaded rod 309 move up and down inside the third threaded cylinder 308. The up and down movement of the fourth threaded rod 309 can drive the inside of the first partition 311 to move up and down. The water inside the water tank 310 is set on the top of the first partition 311. When the display box 312 is expanded outward, the first partition 311 can move upward inside the water tank 310, so that the water inside the water tank 310 enters the inside of the display box 312 through the water pipe 315. The display box 312 is made of a transparent material, and a scale mark is engraved on the outside of the display box 312. The staff can judge the stress at the top by observing the water level inside the display box 312. When the stress at the top disappears, the first partition 311 moves downward, thereby driving the connecting rod 314 to move downward, and then driving the second partition 313 to move downward. The downward movement of the second partition 313 can squeeze the water inside the display box 312, so that the water inside the display box 312 re-enters the inside of the water tank 310 through the water pipe 315, and at the same time, the water level inside the display box 312 will also drop, so that the staff can monitor the stress by observing the change of the water level inside the display box 312.

[0028] When the protection plate 205 is unfolded outward, the second tooth plate 216 can be driven to move, and then the second gear 401 can be driven to rotate, and then the H-shaped plate 403 slidably installed in the second sliding groove 402 can be driven to move up and down, so as to drive the fourth gear 405 to rotate, and the rotation of the fourth gear 405 can drive the fifth gear 406 to rotate, and the rotation of the fifth gear 406 can drive the sixth gear 407 to rotate, and the rotation of the sixth gear 407 can drive the rotating shaft 408 to rotate, and the rotation of the rotating shaft 408 can drive the lever 409 to rotate, and the rotating lever 409 can make the blocking rod 411 and the rotating plate 410 rotate, and the rotation of the rotating plate 410 can drive the connecting shaft 412 to rotate. The eccentric rotation of the connecting shaft 412 can drive the reciprocating rod 413 to slide upward inside the mounting tube 414, and the upward sliding of the reciprocating rod 413 can drive the piston plate 415 to slide upward, and the upward sliding of the piston plate 415 can squeeze the second spring 416. When the lever 409 drives the baffle rod 411 to rotate to a certain angle, no force is generated between the lever 409 and the baffle rod 411, and the second spring 416 returns to its original state under the action of the elastic force, so that the reciprocating rod 413 can be instantly restored to its original position, and the hammer head 417 can fall downward at a very high speed. The downward falling of the hammer head 417 can hammer the metal plate 418, causing the metal plate 418 to make a sound, thereby warning the staff.
