The water condition elevation calibration device further comprises a pay-off angle digital display piece 58, the pay-off angle digital display piece 58 is sleeved on the main shaft 56 for rotary fit, a cycloid arm 581 and an angle pointer 582 which extend to the stranded wire sleeve 55 are arranged on the cycloid arm 581, a long groove 583 for a rope 6 to pass through is axially formed in the cycloid arm 581 along the stranded wire sleeve 55, the long groove 583 and the axis of the stranded wire sleeve 55 are located on the same vertical line path, an angle window 512 and an angle scale are formed in the position, corresponding to the angle pointer 582, of the shell 51, the float 5 is parallel to the water surface, the counterweight anchor falls on the ground, the pay-off angle digital display piece rotates along with the inclination of the rope 6 to obtain the degree of an included angle between the rope 6 and the ground, and the data processing platform obtains an elevation approximate value of the float 5 relative to the ground through a sine function according to the pay-off length value and the degree of the included angle between the rope 6.
When there is a current at the matrix point, the float 5 tends to drift away with the current impact and is not in a vertical position with the weight anchor 4, resulting in elongation of the rope 6 beyond the actual elevation distance.
The invention therefore contemplates a pay-off angle display 58, with the float 5 being held parallel to the water surface by the buoyancy material 52, and the weight anchor 4 being fixed to the ground, also parallel to the ground, with both being offset, with only the rope 6 being inclined.
Through the pay-off angle digital display 58 coaxially arranged with the stranded wire sleeve 55, as the rope 6 passes through the long groove 583 of the cycloid arm 581, the long groove 583 and the axis of the stranded wire sleeve 55 are in the same vertical line path, when the rope 6 tilts, the cycloid arm 581 can be impacted, so that the pay-off angle digital display 58 swings synchronously, the relationship between the tilting angle of the rope 6 and the rotation angle of a pointer is tested in advance, a scale table is formed, the tilting angle of the rope 6 can be reversely pushed out through the pointer to obtain a close angle value in the subsequent use, and then the elevation approximation value of the float 5 relative to the ground is obtained through a sine function through the known pay-off length value and the included angle degree of the rope 6.
The counterweight anchor 4 is provided with a locking mechanism, the locking mechanism comprises a hook arm 41, a sliding block 42 and a return spring 43, the vertical bottom surface of the counterweight anchor 4 is provided with a sliding groove 44, the outer circumferential surface is provided with a hinge seat, the hinge seat is provided with a through groove 47 penetrating through the sliding groove 44, one end of the hook arm 41 is hinged with the hinge seat, the other end hooks the float 5, the hook arm 41 surrounds the hinge end, a plurality of teeth 45 extending into the sliding groove 44 through the through groove 47 are arranged around the hinge end, the sliding block 42 is inserted into the sliding groove 44 to be vertically matched with the sliding groove 44, the sliding block 42 is provided with a rack 46 corresponding to the side surface of the through groove 47 along the vertical direction, the return spring 43 is arranged between the groove bottom of the sliding groove 44 and the sliding block 42, the rack 46 is meshed with the teeth 45 on the hook arm 41, the counterweight anchor 4 falls on the ground, the rack 46 drives the hook arm 41 to rotate around the hinge seat to be unfolded, and the float 5 is unhooked and separated from the counterweight anchor 4.
Because the weight of the counterweight anchor is large, and the buoyancy material 52 is arranged on the floating piece, the natural counterweight anchor 4 falls to the water channel in the downward posture after the device enters water, the sliding block 42 contacts the ground, the rack 46 drives the hook arm 41 to rotate to the side far away from the floating piece, the floating piece is unhooked from the counterweight anchor 4, and the buoyancy material 52 drives the floating piece to automatically separate and rise. While the hook arms 41 are unfolded, supporting feet are formed to hook the bottom surface, so that the balance weight anchor is further kept stable.
A first torsion spring is arranged between the main shaft 56 and the stranded wire sleeve 55, and the first torsion spring drives the stranded wire sleeve 55 to rotate relative to the paying-off direction; a second torsion spring is arranged between the hook arm 41 and the hinge seat, and the second torsion spring drives the hook arm 41 to rotate towards one side of the floating piece.
The torsion spring arranged at the stranded wire sleeve 55 prevents the rope 6 from loosening naturally, and the rope 6 can be rewound to a certain extent along with the water level, so that the counting is automatically corrected. And the water surface rises, the buoyancy is larger than the torsion force of the torsion spring, and the rope is automatically unreeled. By providing a torsion spring at the hook arm 41, the hook arm 41 can be prevented from being spread out in advance.
