What are the advantages and disadvantages of underwater cameras?

The underwater camera has its own unique advantages, but it also exists its own shortcomings. The main features are in the following three aspects:

1) The images returned when encountering turbid water are blurred, and the parts to be inspected cannot be observed very well, or even cannot be seen.

2) The simple camera can only be pre-installed in a fixed location. It cannot be inspected within a certain range under the control of the operator. The efficiency is not high enough.

3) It is pre-installed on the gate. It may collide with other objects during the submerged water and cause damage.

Despite the shortcomings of underwater cameras, as an auxiliary device for troubleshooting, it has an active role in the maintenance of the turbine generator units.

The operation of the six cascade power station reservoir areas in the Lixian River Basin in Yunnan Datang International is sufficient to illustrate this point. Therefore, the water quality of the reservoir is excellent, and turbidity is rarely encountered during the maintenance period, which effectively avoids the turbidity of the water flow. it is not possible to tour the inspection within the predetermined range, the efficiency is not high enough, and it is susceptible to collisions. Depending on the actual situation of each power station, the underwater robot can be used to install the camera.

The biggest advantage of underwater cameras is to intuitively and truly reflect the problems that exist under water, ordinary cameras are moderately priced and suitable for most hydropower plants. They have special advantages in solving underwater problems in hydraulic engineering. Under the premise of changing the existing basic equipment of the power plant, it is an effective method to help eliminate common underwater problems in the maintenance process of the hydropower unit. This equipment has succeeded in the use of the company. It has a very high application value in the inspection and repair process of the turbine generator unit. It is an effective tool for the maintenance personnel to deal with the problems under the water.

Judging from the effect of introduction and use , it has low investment , high efficiency and remarkable economic benefits , and plays an active role in saving expenses and striving for crew maintenance period . It can be extended to its water and electricity station machine unit by step-by-step completion, promotion and promotion to its water power hub new application.
