Description

Technical Field

[0001] The utility model relates to the technical field of Secchi disk auxiliary equipment, in particular to an automatic lifting device applied to a Secchi disk. Background Art

[0002] The Secchi disk is a testing device used to measure the transparency or light transmittance of water. The disk is divided into four black and white parts from the center. The transparency of water depends on the turbidity (the degree of turbidity caused by various plankton and suspended matter in the water) and the chromaticity (the color caused by suspended organisms and dissolved organic matter). When using it, sink the Secchi disk to a depth that is just not visible, so as to calibrate the maximum transparency of water.

[0003] When measuring water transparency, the Secchi disc needs to be equipped with a lead sinker, a measuring line with scale marks and a wire take-up box for controlling the lifting and lowering to assist in the operation. The lead sinker is installed at the bottom of the Secchi disc to act as a counterweight, and then one end of the measuring line is connected to the Secchi disc, and the other end is wrapped around the rotating shaft of the wire take-up box. The Secchi disc is then placed in the external water area to be tested. The staff holds the wire take-up box and manually controls the rotation of the rotating shaft in the wire take-up box by shaking the handle, thereby driving the measuring line to drive the Secchi disc to be raised and lowered, so that the Secchi disc can be placed flat in the water and gradually sink until the white color of the disc surface can no longer be seen. The length mark value of the measuring line below the water surface is recorded, which is the water transparency, to complete the water transparency detection operation.

[0004] However, in actual operation, it is inconvenient to stably control the lifting and lowering of the measuring line by manually operating the take-up box, and the working height is prone to change, which affects the stability of the Secchi disk during lifting operations. Furthermore, it is inconvenient to drive the Secchi disk to automatically lift and lower the measuring line by manually operating the take-up box. This makes it inconvenient to adjust the lifting height of the Secchi disk, affecting the convenience of the lifting and lowering adjustment operation when operating the Secchi disk to measure water quality transparency.

The small battery is arranged on the bracket, and the measuring line of the power supply end of the small battery is electrically connected to the self-locking motor.

[0010] Furthermore, a slide groove is opened on one side wall of the slide seat, a bolt is passed through the slide groove, one end of the bolt is threadedly connected to a preset screw hole on the side wall of the mounting plate, and a rubber pad is sleeved on one end of the bolt, and the rubber pad abuts against the side wall of the slide groove.
