The invention discloses a submarine floating icebreaking load measurement test device and a submarine floating icebreaking load measurement test method. The submarine floating icebreaking load measurement test device comprises a test box, an ice block clamp, a moving assembly, a lifting assembly, an angle adjusting assembly and an observation assembly. Wherein the ice block clamp, the moving assembly, the lifting assembly and the angle adjusting assembly are all arranged in the test box, the ice block clamp is used for fixing ice blocks, the moving assembly is used for driving the submarine model to move in the horizontal direction, the lifting assembly is used for driving the submarine model to move in the vertical direction, and the angle adjusting assembly is used for adjusting the pitch angle of the submarine model. The observation assembly is used for recording the stress condition and the water outlet posture of the submarine model. According to the test device, the position and posture of the submarine model can be adjusted through the moving assembly, the lifting assembly and the angle adjusting assembly, so that different icebreaking conditions are simulated; and the icebreaking process of the submarine model is recorded through a force sensor and a camera. The invention relates to the field of submarine icebreaking test research.

The present invention relates to the technical field of corrosion resistance test equipment, and discloses a flow mixed gas corrosion test device, including a body, a test chamber is opened on the top of the front of the body, and a mixing box is fixedly installed on the back of the body. The flow mixed gas corrosion test device, by arranging a heating sleeve, a first heating plate and a second heating plate, can preliminarily heat the mixed gas inside the mixing chamber due to the design of the first heating plate, and the mixed gas carrying humidity will be heated and insulated for a second time due to the design of the heating sleeve, so as to prevent condensation water from being generated in the pipeline, and the design of the second heating plate can achieve heating and insulation of the internal environment of the test chamber, so as to avoid condensation water from being generated inside the test chamber, and at the same time, due to the cooperation between the heating sleeve, the first heating plate and the second heating plate, the temperature of the mixed gas can be changed to meet different test requirements, thereby increasing the practicality of the device.

This utility model discloses a reverse osmosis test device for nuclear power industry wastewater, including a main frame consisting of a horizontally arranged chassis and a support. A high-pressure pump is mounted on the chassis, and a reverse osmosis membrane is detachably mounted on the support. The outlet of the high-pressure pump is connected to the inlet of the reverse osmosis membrane via a pipe. The clear water outlet of the reverse osmosis membrane is connected to a pipe, and the high-concentration water outlet of the reverse osmosis membrane flows back to the inlet of the reverse osmosis membrane via a pipe. The reverse osmosis membrane is connected to the pipe via a quick-release connecting device. Roller components are provided at the bottom of the chassis. This utility model allows for the replacement of different models of reverse osmosis membranes, facilitating multiple tests with different models of reverse osmosis membranes based on varying raw water data requirements. Furthermore, the reverse osmosis membrane is easy to install and remove, and the operation is simple.
