Description

A seawater transparency measuring instrument

technical field

The utility model relates to a marine detection device, in particular to a seawater transparency measuring instrument.

Background technique

Seawater transparency refers to the degree of clarity of the ocean water body, and is a very intuitive marine environment parameter. In the field of marine environment research, the transparency of seawater is an important factor affecting the working distance of underwater optical imaging and underwater laser detection. With the continuous development of ocean detection technology, the measurement of seawater transparency is becoming more and more important in the development of underwater optical imaging technology. This parameter provides an important basis for the performance evaluation of underwater optical imaging system and the analysis of factors affecting underwater imaging quality. .

At present, the seawater transparency is mainly measured by the Sebster disc method. The Sephardt disc method is a commonly used on-site seawater transparency measurement method. This method uses a white disc to observe the transparency in water. The specific operation process is as follows: the tester puts a white disc (the diameter of the white disc is 30cm ) into the seawater vertically until just invisible; the depth at which the white disc disappears is called transparency. However, this measurement method requires manual operation and observation, and cannot be permanently installed. It is difficult to realize the water quality within a certain time range. Continuous measurement will cause difficulties, and manual close-range observation is required, resulting in inconvenient operation.

Utility model content

Purpose of the utility model: In order to overcome the deficiencies of the prior art above, the utility model provides a seawater transparency measuring instrument. The operator can observe the observation camera through the wireless transmitter, which avoids close-range observation, is easy to operate, and can realize remote control. Good practicality.

Technical solution: A seawater transparency measuring instrument, including a ship's side chamber, a support rod, a guide wheel, an observation camera, and a disc; 2. Motor, reel, screw, slider, wireless transmitter;

Wherein, the first motor drives the screw rod, the screw rod engages the thread set in the center of the slider, the upper end of the slider is connected to the inner end of the support rod, the support rod is parallel to the screw rod and the inner end is placed in the ship's side compartment, and the outer end of the support rod extends out of the ship's side compartment The end of the support rod is provided with a bracket to install the observation camera. The outer end of the support rod is connected to the guide wheel. Driven by two motors, the wireless transmitter is placed on the upper side of the ship's side compartment, and the storage battery provides working power for the first and second motors and the wireless transmitter.

Further, the slider is fixedly connected to the support rod.

Further, the guide wheel is flexibly connected to the support rod.

Further, the second motor is provided with a detection sensor.

Beneficial effects: the utility model has a simple structure and a reasonable design. By setting the first motor, the second motor, the observation camera and the wireless transmitter, the ship side warehouse is set in the seawater, and the first motor drives the screw to rotate, so that the slider moves and the The support rod is pushed out to the outside, and then the second motor drives the reel to rotate so that the disc sinks into the seawater. The operator realizes the observation camera through the wireless transmitter to observe, avoiding close-range observation, easy to operate, and the detection sensor can effectively Detect the length of the connecting rope, so that remote control can be realized, and the practicability is good.
