Specifically, in an initial state, the swing arm 104 is in a loose or swing state, the stopper 512 is suspended in the mounting groove 501 by a tension spring, the shift lever 510 is also integrally located in the mounting groove 501, the compression spring 421 pushes the embedded post 419 to approach the inner baffle, at this time, the mounting groove 501 and the trigger groove 517 are not in an aligned position, the stopper 512 is integrally in a cylindrical structure, the slider 602 is initially located in the stopper 512, and the clamping post 606 is located in the sliding hole 605.

When the device is used, firstly, the swing arm 104 and the swing block 108 are pulled to move to the right side to be at a certain height, the outer baffle 418 and the embedded column 419 are close to each other, the mounting groove 501 and the trigger groove 517 are in aligned positions, the power accumulating gear 414 and the spur rack 416 are in a meshed state, then the pull rope 520 is pulled to pull the stop block 512 into the trigger groove 517, the telescopic device 503 composed of the short rod and the long rod 505 is in an extended state, the slide block 602 on the left side in the stop block 512 slides to the left side of the shift lever 510 to the left side of the stop block 512 under the influence of self gravity, the clamping column 606 on the same side also extends out of the slide hole 605, as shown in fig. 12, at this time, the pull rope 520 is loosened, the stop block 512 is pulled upwards by the tension spring, the telescopic device 503 is contracted, the motion of the shift lever 510 relative to the stop block 512 can be divided into linear motion in the axial direction and linear motion in the radial direction, and the slide block 602 on the left side is pushed to move to the right by the linear motion, so that the slide block 602 on the left side cannot completely return to the cylinder of the stop block 512, when the stopper 512 drives the left slider 602 to move upward to the position where the slide hole 605 corresponds to the slot 519, the left clip column 606 extends into the left slot 519, the stopper 512 is locked in the trigger slot 517 and cannot move upward, and at this time, the swing arm 104 starts to swing.

The swing arm 104 swings to the left, the transmission gear 401 rotates around the buffer plate and the rack in the arc structure, the transmission gear 401 rotates clockwise to drive the transmission ratchet 409, the power accumulation gear 414 and the locking ratchet 410 to rotate clockwise, the power accumulation gear 414 rotates clockwise to drive the spur rack 416 to move downwards, the spur rack 416 drives the power accumulation column 404 to move downwards, and the power accumulation spring 405 on the upper portion of the power accumulation column 404 is compressed; before the swing arm 104 reaches the vicinity of the vertical position after being released, the swing arm 104 is in an acceleration stage, when the lower side of the swing arm 104 swings to the left, the stopper 512 can be driven by the swing arm 104 to swing to the left by taking the connecting shaft 110 as a supporting point, the swing speed of the stopper 512 can provide a centrifugal force, the centrifugal force can enable the stopper 512 to move downwards by overcoming the tensile force of the tension spring, the slider 602 on the left side of the stopper 512 can be pulled back to the inner side of the shift lever 510 by the tension spring of the slider 602 on the left side, the stopper 512 is still in the trigger groove 517, the outer baffle 418 and the embedded column 419 are continuously prevented from being away from each other, the force storage gear 414 and the spur rack 416 are kept in a meshed state, when the swing arm 104 swings to the vicinity of the vertical position, the centrifugal force borne by the stopper 512 is the largest, the telescopic device 503 is pulled to the longest, the influence of the gravity component is reduced, and the slider 602 on the left side is pulled back to the vicinity of the axis position of the stopper 512 by the tension spring of the slider 602.

After the swing arm 104 is in a deceleration stage after swinging to a vertical position, the swing block 108 has been swung to a certain height to the left side at this time, the right slider 602 in the stopper 512 slides to the right side under the action of gravity component force and slides to the outer side of the right deflector rod 510, when the swing speed of the swing arm 104 to the left side is reduced to a certain value, the swing speed of the stopper 512 is reduced, the centrifugal force applied to the stopper 512 is reduced, the stopper 512 is pulled upwards by the tension spring, at this time, the deflector rod 510 on the right side of the stopper 512 prevents the right slider 602 from moving to a direction close to the axis of the stopper 512, the right latch 606 also extends out of the right slide hole 605 due to self gravity, when the slide hole 605 of the right slider 602 and the right latch groove 519 on the right side are at the same height, the right latch 606 enters the latch groove 519, the stopper 512 is latched by the right latch 606, when the swing block 108 swings to the left peak, the stopper 512 is still in the latch groove 517, outer stop 418 remains in close proximity to inset column 419 and power gear 414 remains engaged with spur rack 416.

When the swinging block 108 swings to the highest point to the left side, the swinging speed is reduced to zero, then the swinging block swings to the right side, when the swinging block 108 swings from the left side to the right side, the transmission gear 401 rotates anticlockwise around the rack 113, the transmission gear 401 rotates anticlockwise and drives the transmission ratchet 409 to rotate anticlockwise, the locking ratchet 410 cannot rotate anticlockwise, the power storage transmission shaft 407 cannot rotate anticlockwise, and the power storage spring 405 on the upper portion of the power storage column 404 cannot release elastic potential energy.

When the swing arm 104 is about to stop swinging, the swinging speed of the swing arm 104 is relatively low, and the swing arm 104 is near the vertical position, at this time, the clamping posts 606 at both sides of the stopper 512 are pulled back into the sliding hole 605 by the tension springs of the clamping posts 606 connected with each other, because the swinging speed is relatively low, the centrifugal force applied to the stopper 512 is reduced, the stopper 512 is pulled back into the mounting groove 501 by the tension springs, if the slider 602 at one side of the stopper 512 is pushed to the outside of the stopper 512 by the shift lever 510 at the same side, the slider 602 slides out along the sliding slope 518 at the outlet of the trigger groove 517, and then the whole calibration structure is pulled back into the vertical mounting groove 501 by the tension springs.

Then, the embedded columns 419 are far away from the outer baffle 418 and close to the inner baffle 420 by the compression springs 421 on the upper side and the lower side of the outer baffle 418, so that the spur racks 416 arranged on the inner side of the power storage columns 404 are disengaged from the power storage gear 414, the power storage gear 414 cannot prevent the spur racks 416 from moving downwards, and the power storage springs 405 on the upper parts of the power storage columns 404 release elastic potential energy to drive the swing arms 104 to vibrate; after the swing arm 104 completely stops moving, the clamping screw is screwed down, so that the swing block 108 is locked with the detection plate 106, the pointer on the reverse side is used for deviation checking of the scale marks, the difference value and the change are calculated to obtain the inclination and the deformation of the water gate, the error influence of the rotation friction force and the gravity factor is solved, the detection accuracy of the device on the plane of the water gate is improved, the timely maintenance and the safe use of the water gate are guaranteed, and the life and property safety of people is further guaranteed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
