At least two groups of frame rods 12 are needed to fix the components, and at least three groups of frame plates 13 are arranged on each group of frame rods 12 to fix the components. The two groups of hack levers 12 are oppositely arranged at two sides of the component, and clamping and fixing of the component are completed through the hack levers 12. Two sets of frame plates 13 positioned above the three sets of frame plates 13 horizontally clamp components. A set of shelves 13 below horizontally support the components.

The first sleeve 131 is sleeved with an elastic device 132. The elastic means 132 push the upper two sets of shelves 13 towards each other. A lower set of shelf plates 13 is fixedly arranged on the first sleeve 131.
The elastic device 132 pushes the two upper groups of frame plates 13 to approach each other, the two upper groups of frame plates 13 clamp the components horizontally, the horizontal direction of the components is limited, the first sleeve 131 drives the lower group of frame plates 13 to rotate, and the lower group of frame plates 13 support the bottom surface of the components and limit the height direction of the components.
The hack lever 12 is also sleeved with a second sleeve 121.

When the frame plates 13 limit the components, high and low gaps exist between the frame plates, flowing salt mist passes through the frame plates 13, and the clamping positions of the components can still be used for salt mist test. Meanwhile, salt mist is prevented from accumulating at the position of the frame plate 13, so that more salt mist is accumulated at the local position of the part, and the salt mist test result is prevented from being influenced. And the salt mist flows between the frame plates 13, and no obstruction is formed, and the air flow of the salt mist is not influenced.
The spraying mechanism 4 comprises a spraying frame 41, a swinging blade 42 for spraying salt mist and a first power device 43 for driving the swinging blade 42 to rotate. The swing blades 42 are rotatably provided in parallel on the spray frame 41. The swing blade 42 is connected to the driving end of the first power device 43.

Brine in the brine source enters the pipeline 45 from the other end of the swing blade 42 and is sprayed out through the spray head 44.
Two streams of salt spray can be formed by spraying salt spray from both sides of the pendulum blade 42. The salt mist sprayed from the spray nozzle 44 near the air blowing device 2 contacts the air flow first, and the flow path of the salt mist is longer, so that the salt mist is more dispersed. The salt mist sprayed out of the spray nozzle 44 at a position far away from the air blowing device 2 contacts with the air flow, and the flow path of the salt mist is shorter, so that the salt mist is more concentrated. One of the two salt mist is dispersed, the other salt mist is concentrated, and when the air blowing device 2 generates air flow to pass through the injection mechanism 4, the two salt mist is alternately blown to the component, so that the salt mist can realize alternate flapping of the component. Thereby simulating the condition of the sea storm, and leading the salt spray test of the component to be more close to the real condition.

The swing rod 311 is connected to the driving end of the sixth power device 312. The sixth power device 312 drives the swing lever 311 and the louver 34 to rotate a certain angle so that the louver 34 can open or close the passage 32.
The fourth power unit 36 drives the impeller 35 to rotate, and the impeller 35 generates an air flow flowing leftward along the passage 32, and suction is formed at a side of the suction bracket 31 close to the component. By opening or closing the louver door 34 at different positions, an adsorption force is formed at different positions on the side of the suction bracket 31 close to the component, and the adsorption force affects the flow direction of the salt mist.

The salt spray test device for ship components further comprises an imaging mechanism 6 for imaging the components and a detection mechanism 7 for detecting the components in the test stand 1. The camera 6 is arranged in the test stand 1 around the component. The detection mechanism 7 is disposed in the test stand 1.
Preferably, the camera mechanism 6 is an industrial camera. Before the salt spray test, the shooting of the component is completed by the shooting mechanism 6, and a three-dimensional model of the component is built. Since the imaging mechanism 6 is provided around the components in the test stand 1, the imaging mechanism 6 can take images of the components from various angles. The three-dimensional model can be used for calculating the data of the salt fog quantity, the flow direction and the path of the salt fog to be settled in advance, so that the service condition of the component is well simulated, and the salt fog test error is avoided.
Preferably, the detection mechanism 7 is a miniature weather detection station. The detection means 7 comprise several detection points. The detection points are distributed in the test stand 1.

The accuracy of the data can be verified by the parameters detected by the detection means 7.
The salt spray test device for ship components further comprises an irradiation mechanism 8 for irradiating the components. The irradiation mechanism 8 includes an irradiation frame 81, a light source 82 of an irradiation member, a blade fan 83 that blows air in the irradiation direction of the external light source 82, and a fifth power device 84 that drives the blade fan 83 to rotate. The leaf fan 83 is rotatably provided in the irradiation frame 81. A fifth power device 84 is provided in the irradiation frame 81.
Preferably, the light source 82 is a light bulb. The irradiation frame 81 is provided on the frame body 11. A light source 82 is provided in the irradiation frame 81 near one end of the component. Preferably, the fifth power device 84 is an electric motor. The blade fan 83 is connected to the driving end of the fifth power device 84.

In the daily use of the component, the component is required to bear the exposure of the sunlight as well as the sea wind and the storm, when the environment of sunlight irradiation needs to be simulated in the salt spray test process, the spraying mechanism 4 is stopped, the air blowing device 2 and the air suction device 3 still generate air flow to bring the salt spray in the test frame 1 out, and then the air blowing device 2 and the air suction device 3 stop working. The light source 82 is turned on and light irradiates the component to complete the insolation of the component. At this time, since the salt content in the test stand 1 is high, a part of salt adheres to the light source 82, and salt particles are formed on the surface of the light source 82 by irradiation of the light source 82, which affects the irradiation effect of insolation. The fifth power device 84 drives the blade fan 83 to rotate and blow air in the irradiation direction, and air flows along the light source 82, so that salt mist is prevented from adhering to the light source 82.
The irradiation frame 81 is provided with a frame door 811 at one end near the component. The frame door 811 is provided on the irradiation frame 81 so as to be relatively slid around the light source 82. The irradiation frame 81 is rotatably provided with a toothed ring 812 near one end of the member. The toothed ring 812 is driven by a seventh power device 813. A fourth gear 814 is rotatably provided in parallel around one end of the irradiation frame 81 near the member. A rack 815 is provided on the housing door 811. The rack 815 slides along the irradiation rack 81. The housing door 811 is coupled to the rack 815. The fourth gear 814 engages one side of the toothed ring 812 and the rack 815, respectively. The drive end of the seventh power device 813 is provided with a fifth gear 816. The fifth gear 816 engages the other side of the toothed ring 812. The seventh power device 813 drives the fifth gear 816 to rotate, the fifth gear 816 drives the toothed ring 812 to rotate, the toothed ring 812 drives the fourth gear 814 to rotate, and the fourth gear 814 drives the rack 815 and the frame door 811 to move.
The rack 815 drives the housing doors 811 to move toward each other, and the housing doors 811 close the light source 82. The rack 815 turns on the light source 82 when the rack door 811 moves away from each other. During salt spray test, the frame door 811 turns off the light source 82, and prevents salt spray from adhering to the light source 82. When the component performs the exposure test, the frame door 811 is opened to open the light source 82, and the rack 815 drives the frame door 811 to move to control the opening degree of the frame door 811, so as to adjust the irradiation range of the light source 82.
