[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-2 As shown, the present invention provides a marine plate salt spray test chamber, comprising a chamber 1, a connecting plate 2, a material placement plate 3, a salt spray generating device 4, a salt spray collecting device 5, a cover 6, and a drain pipe 8.

[0033] Both walls of the housing 1 are provided with several connecting plates 2. The connecting plates 2 are "L" shaped and form a connection channel with the side wall of the housing 1.

[0034] like Figure 4-5 As shown, the top of the material placement plate 3 has several inclined material placement grooves 32, and the two sides of the material placement plate 3 are provided with buckle plates 31, which are fastened into the connecting channel.

[0035] The test plate is inserted into the inclined material placement groove 32, which has an inclination angle of 15-30°, so that the plate is kept in an inclined state of 15-30° to avoid the droplets of test salt water from accumulating on the plate and affecting the uniformity of the test.

[0036] Depending on the size of the material to be tested, different heights of the placement plate 3 on the connecting plate 2 can be selected, and the placement plate 3 is fastened to the connecting plate 2 by the fastener 31. This detachable connection structure makes it easy to adjust the horizontal position of the placement plate 3 according to the size of the material, and makes it easy to place more materials flexibly.

[0037] like Figure 6 As shown, the salt spray generating device 4 includes a water storage frame 41, a cover plate 47, and a mist outlet pipe 42. The mist outlet pipe 42 is connected to the water storage frame 41 through the cover plate 47. The water storage frame 41 is connected to a test salt water tank. The test salt water is introduced into the water storage frame 41. The mist outlet pipe 42 is connected to an existing atomizing device. Compressed air is atomized into tiny droplets through a nozzle. The atomized salt spray is evenly distributed in the box 1.

[0038] The salt spray generating device 4 also includes a connecting frame 43, which is provided with a conical baffle 44. The conical baffle 44 is located above the mist outlet of the mist outlet pipe 42. The wall of the conical baffle 44 can play a guiding role. The salt spray discharged from the mist outlet pipe 42 is dispersed in all directions along the wall of the conical baffle 44, so as to avoid the salt spray from concentrating in the same area and affecting the test results.

[0039] The bottom of the connecting frame 43 is provided with a connecting ring 45, which is fitted onto the outer wall of the mist outlet pipe 42. The first fastener 46 detachably connects the connecting ring 45 to the mist outlet pipe 42. By loosening the first fastener 46 and moving the connecting ring 45 up and down, the height of the connecting frame 43 can be adjusted, thereby adjusting the distance between the conical stop 44 and the mist outlet of the mist outlet pipe 42, and thus adjusting the mist output.

[0040] like Figure 3 and Figure 7 As shown, the bottom of the box 1 is equipped with a first drain plug 11, a second drain plug 12, and an overflow pipe 13, as follows: Figure 7 As shown, the drain pipe 8 is connected to a first outlet pipe 81, a second outlet pipe 82, and a third outlet pipe 83. The first drain plug 11 is located at the opening of the first outlet pipe 81, the second drain plug 12 is located at the opening of the second outlet pipe 82, and the overflow pipe 13 is connected to the third outlet pipe 83. The second outlet pipe 82 is located between the first outlet pipe 81 and the second outlet pipe 82, and the third outlet pipe 83 is close to the outlet of the drain pipe 8. A ball valve 84 is provided between the second outlet pipe 82 and the third outlet pipe 83.

[0041] After long-term salt spray testing, test salt water will accumulate inside the chamber 1. As the level of the test salt water in the chamber 1 gradually rises, in order to prevent the connecting plate 2 and the material plate 3 from being immersed in the test salt water, the first drain plug 11 and the ball valve 84 can be opened to drain the water.

[0042] To prevent excessive test salt water in the chamber from being drained without timely manual intervention, the height of the overflow pipe 13 at the bottom of the chamber 1 determines the storage depth of the test salt water in the chamber 1. When the liquid level of the test salt water in the chamber 1 exceeds the opening of the overflow pipe 13, the test salt water is automatically discharged from the chamber 1 through the drain pipe 8 from the overflow pipe 13, which is always kept open.

[0043] When it is necessary to clean the tank 1, the ball valve 84 can be opened and the first drain plug 11 can be opened to discharge the test salt water that is lower than the height of the overflow pipe 13 through the first outlet pipe 81 and the drain pipe 8; the second drain plug 12 can be opened to discharge the remaining water in the water storage frame 41 through the second outlet pipe 82 and the drain pipe 8.

[0044] like Figure 2 and Figure 8 As shown, one or more salt spray collection devices 5 are installed inside the chamber 1. Each salt spray collection device 5 includes a collection funnel 51, a transmission pipe 52, and a collection test tube 53. The collection funnel 51 is connected to the collection test tube 53 through the transmission pipe 52. The reliability of the salt spray test depends on the uniformity and stability of salt spray deposition. The collection funnels 51 are distributed at different locations within the chamber 1 to collect salt spray condensate. The liquid is transferred from the transmission pipe 52 to the collection test tube 53 to test the amount of salt spray deposition, ensuring the accuracy of the test results.

[0045] The housing 1 is equipped with a detection window 14, which is connected to an openable access door 15 via an existing latch 16. The collection tube 53 is located at the detection window 14. When testing the salt spray deposition rate, after the collection tube 53 collects the salt spray condensate, the access door 15 is opened, and the collection tube 53 is taken out from the detection window 14, making it convenient to measure and record the amount of salt spray condensate collected in the tube.

[0046] The chamber 1 is equipped with an openable cover 6. Sealing grooves 18 are provided around the top opening of the chamber 1. During testing, the four sides of the cover 6 are located within the sealing grooves 18. During testing, the cover 6 is closed, and water is filled in the sealing grooves 18 to increase the airtightness of the cover 6 to the chamber 1, thus improving the salt spray test effect. Before and after testing, the cover 6 needs to be opened for easy material handling and routine inspection and maintenance of the chamber 1.

[0047] The cover 6 is equipped with a handle 61 for easy opening and closing by hand. The cover 6 is preferably a transparent cover, which allows the tester to directly observe the fogging situation inside the chamber 1 during the test.

[0048] The housing 1 is provided with a limiting plate 7, and the limiting plate 7 is provided with a protective pad 71. The protective pad 71 faces the cover 6. When the cover 6 is opened, the limiting plate 7 can limit the maximum opening range of the cover 6 and provide support for the cover 6 in the open state. The protective pad 71 provides protection for the cover 6 and avoids frequent collisions between the repeatedly opened cover 6 and the limiting plate 7, which would cause wear to the cover 6.

[0049] This utility model discloses a salt spray test chamber for marine plates. The cover 6 is opened, and the plates to be tested are inserted into the material slots 32 of the material plate 3 in appropriate positions. The cover 6 is then closed, and the test salt water prepared according to the required test standard ratio is atomized by the salt spray generator 4. The chamber 1 is equipped with an existing temperature and humidity control system to ensure that the temperature and humidity of the test environment are maintained within the required range, thereby realizing the salt spray test on the plates inside the chamber 1.

[0050] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
