Embodiment Construction
[0023] see figure 1 , the electric hoist 2 is fixed on the hanger 1, the rope drum winding number sensor 7 is set on one side of the hoist rope drum 3, the hook of the rope drum steel wire rope 5 is connected to the water quality detection device 6, and the water quality detection device 6 is respectively provided with a water surface Sensor 8 and bottom sensor 9.
[0024] see Figure 2A , Figure 2B and Figure 2C , the setting of the rope drum number of turns sensor 7 is: the rope drum end plate 4 that rotates with the gourd rope drum 3 is set on one side of the gourd rope drum 3, and the rope drum end plate 4 is located on the outer end surface of the rope drum end plate 4. On the same circumferential position of each rotating speed sensor magnet block 14 is uniformly arranged, and a machine box 15 is set in the rope drum reduction box 12 corresponding to the rope drum end plate 4, and there are two speed sensor magnet blocks in the machine box 15. The Hall element 16 i...

The invention discloses an underwater penetration sensor in a water quality detector. The underwater penetration sensor in the water quality detector is characterized in that the water quality detector is provided with a water level sensor and an underwater sensor; the electric block of the water quality detector is provided with a rope drum winding number sensor. When the water quality detector is used for detecting water quality, the water level sensor transmits signals after the detector arrives at the water level; the rope drum winding number sensor on the electric block starts to accountthe underground penetration, so that the water quality detector can detect a plurality of water quality indexes according to the appointed water depth accurately; when the detector arrives the water bottom, the underground sensor transmits a signal, and the electric block stops lowering the water quality detector. The underwater penetration sensor has the characteristics of high precision, good resolution, reliable working, simple operation, automatic control and the like; and the underwater penetration sensor is an advanced detection auxiliary apparatus.
Description
technical field [0001] The invention relates to a control device for the water entry depth of a water quality detection device, in particular to a water entry depth sensor of the water quality detection device. Background technique [0002] Water quality testing in the prior art uses equipment such as manual hoists or electric hoists, which can only lift and lower the water quality testing device, and cannot hoist the water quality testing device into a designated water depth for water quality testing in a controlled manner. Contents of the invention [0003] In order to avoid the shortcomings of the above-mentioned prior art, the present invention provides a water entry depth sensor for a water quality detection device, in order to accurately measure the position where the water quality detection device reaches the water surface or the bottom of the water, and the depth of the water entry, so that the water quality detection The device can accurately detect various water ...
