Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] Depend on figure 1 and figure 2 It can be seen that the present invention includes the main structure of the observation tube, a transparent top cover 1, a fixed rod 3, a balance buoy 2, a miniature remote control camera 4, a scale 5, a desiccant 7, a sand filling port 8, an underwater lighting lamp 9, and a sand filling port. A dozen parts of the stone counterweight box. The main structure of the observation tube is made of transparent plexiglass, and the plexiglass wall 6 needs to have a certain thickness (at least 5mm) to ensure a certain compressive strength, so as to prevent the observation tube from being cooled by the air in the tube during the formation or development of the ice sheet. At the same time, it bears ice pressure and shrinks, deforms or even destroys. The main body of the observation tube is a hollow columnar structure, which is...

Abstract

The invention discloses an optical ice thickness observation barrel, and belongs to the technical field of automatic monitoring. The optical ice thickness observation barrel is used for automatically monitoring the ice layer thickness of river ice, lake ice and sea ice. The optical ice thickness observation barrel comprises an observation barrel body and balance float bowls connected with the observation barrel body. The observation barrel body is overall of a hollow cylindrical structure and is divided into an upper space and a lower space. A dividing ruler is arranged on the edge wall of one side of the upper space, a minitype remote control camera is arranged on the edge wall of the inner side, opposite to the dividing ruler, of the upper space, the remote control camera is used for shooting images, the images are transmitted in a wireless mode, the formation, disappearing and development of an ice layer can be automatically monitored in real time, convenience and rapidness are achieved, the labor intensity is lowered, and the monitoring efficiency is improved. According to the optical ice thickness observation barrel, the structure is simple, the steps of the measuring method are simple, the dividing ruler is used for reading directly, measuring errors are small, and measured data are reliable. The optical ice thickness observation barrel is not limited by a measured water area and cannot be influenced by the ambient environment temperature change, and thus good practicability and applicability are achieved.

Description

technical field [0001] The invention relates to an ice layer thickness measuring device, which belongs to the technical field of automatic monitoring, and is mainly applicable to technical fields such as water conservancy and hydrology, and is used for automatic monitoring of the ice layer thickness of river ice, lake ice and sea ice. Background technique [0002] The winter in northern my country is very cold, and the freezing period of rivers, lakes, and reservoirs is long. In practical activities such as operating on ice, ensuring the safety of water delivery under the ice cover during the ice age of water delivery channels, and preventing ice hazards, the thickness of the ice layer is a very important basis. However, there is currently a lack of fast, accurate and relatively economical technical methods and means for real-time automatic monitoring of ice thickness. The current measurement methods of ice thickness mainly include: [0003] (1) Direct measurement Direct mea...
