Description

Technical Field

[0001] This utility model belongs to the technical field of salt spray test chambers, specifically, it relates to a salt spray test chamber with a shelf. Background Technology

[0002] The existing salt spray test chamber is a device used to test the salt spray corrosion resistance of materials and their protective layers. It simulates the salt spray corrosion environment of a marine climate to test the corrosion performance of various materials such as electrical equipment and metal products.

[0003] Chinese patent application CN202420260778.5 discloses a salt spray testing machine with a self-cleaning mechanism. It includes an outer shell and a shelf installed inside the shell. A second water pipe is located at the lower end of the outer shell, with a sealing ring on the right side and a spray head at the upper end. A chamber cover is installed on the upper side of the outer shell, with a limit strip on the lower side and a handheld bracket on the upper side. The machine also includes a salt water tank located inside the shelf, with a water pump at the lower end. A first water pipe is connected to the left side of the water pump, and an atomizing component is installed at the left end of the first water pipe. A first drain outlet is located on the right side of the outer shell. This prior art allows for the replacement of damaged atomizing components after use and enables the cleaning of the inner wall of the device, making it less susceptible to salt spray corrosion and exhibiting good adaptability.

[0004] However, the aforementioned existing technologies still have shortcomings in practical use and need improvement. Typical existing technologies usually require placing the object to be tested on the upper side of a shelf, and then using an atomizing component to atomize the salt water to simulate the environment. Direct placement can easily cause the part in contact with the shelf to not fully contact the atomized environment, thus affecting the uniformity of the test results. Furthermore, if the salt solution is in a relatively static state, the salt in the solution may gradually precipitate, especially when the solution concentration is high or the temperature is low, leading to deviations in the subsequent atomization simulation and affecting the accuracy of the detection. In view of these issues, this utility model is proposed. Utility Model Content

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides a salt spray test chamber with a shelf, including a housing 1. A shelf 2 is provided on the lower side of the inner wall of the housing 1. The shelf 2 is a housing with a space for storing salt solution inside. A fixing plate 3 is provided on the upper side of the shelf 2. A rotating rod 4 is rotatably connected to one side of the fixing plate 3. A first clamping ring 5 is provided on one side of the rotating rod 4. A drive box 6 is provided on one side of the shelf 2. A double-headed motor 7 is provided on one side of the inner wall of the drive box 6. A first driving bevel gear 8 is fixedly connected to the upper end of the double-headed motor 7. A first driven bevel gear 9 that cooperates with the first driving bevel gear 8 is fixedly connected to one end of the rotating rod 4.

[0029] Please see Figure 1 Multiple support legs 17 are fixedly connected to the lower side of the box body 1, and anti-slip pads 18 are fixedly connected to the lower side of the multiple support legs 17. The support legs 17 are used to support the weight of the whole, and the anti-slip pads 18 can increase the stability when placed.

[0030] Please see Figure 1 The shelf 2 has an observation opening 13 on one side. A transparent glass 14 is fixedly connected to the inner wall of the observation opening 13. The capacity of the shelf 2 can be observed through the observation opening 13 via the transparent glass 14.

[0031] Please see Figure 1 A water inlet 15 is provided on one side of the shelf 2. A protective plug 16 is provided on the inner wall of the water inlet 15. Salt water can be added to the inside of the shelf 2 in a measured amount through the water inlet 15. The protective plug 16 can protect the water inlet 15 when it is not in use.

[0032] The upper side of the shelf 2 is provided with a tightening component 10 that cooperates with the first clamping ring 5, the inner wall of the shelf 2 is provided with a stirring component 11 that cooperates with the double-head motor 7, and the lower side of the inner wall of the box 1 is provided with an atomizing component 12.

[0033] Please see Figure 2 The tightening assembly 10 includes a slotted plate 101 fixedly connected to the upper side of the shelf 2, a lead screw 102 rotatably engaged with one side of the inner wall of the slotted plate 101, a tightening plate 103 threadedly engaged with the lead screw 102 and slidably engaged with the slotted plate 101, and a tightening ring 104 rotatably engaged with one side of the tightening plate 103. By rotating the lead screw 102, the tightening plate 103 can be pushed to move in the direction of the rotating rod 4 to tighten and fix both ends of the object. The tightening can be achieved by rotating the first clamping ring 5, which can rotate the tightened item. The tightening ring 104 will rotate on the tightening plate 103 without causing any impact.

[0034] Please see Figure 2 and Figure 3 The stirring assembly 11 includes a stirring rod 111 rotatably fitted on the upper side of the inner wall of the shelf 2, a stirring blade 112 fixedly connected to the stirring rod 111, a worm gear 113 fixedly connected to the stirring rod 111, a worm 114 rotatably fitted on one side of the shelf 2 and meshing with the worm gear 113, a second driven gear 115 fixedly connected to the worm 114 and located on the inner wall of the drive box 6, and a second driving gear 116 fixedly connected to the lower end of the dual-head motor 7 and meshing with the second driven gear 115. When the dual-head motor 7 rotates, the second driving gear 116 drives the second driven gear 115 to rotate, thereby rotating the worm 114 and the worm gear 113, which in turn causes the stirring rod 111 to drive the stirring blade 112 to rotate and stir the liquid inside the shelf 2, reducing the occurrence of sedimentation.

[0035] Please see Figure 1 and Figure 2 The atomizing component 12 includes two liquid pumps 121 fixedly connected to the lower side of the inner wall of the housing 1, L-shaped tubes 122 fixedly connected to the output ends of the two liquid pumps 121, and atomizing nozzles 123 fixedly connected to the near ends of the two L-shaped tubes 122. The input end of the liquid pumps 121 extends into the interior of the shelf 2 through a pipe. Liquid is drawn from the shelf 2 by the liquid pumps 121 and injected into the atomizing nozzles 123 through the L-shaped tubes 122. The salt water can be atomized by the atomizing nozzles 123.

[0036] The implementation principle of a salt spray tester with a shelf in this application embodiment is as follows: When in use, a certain amount of salt water is first injected into the inside of the shelf 2, then the box 1 is opened, and the hardware to be tested is placed between the first clamping ring 5 and the tightening ring 104. The screw 102 rotates in the empty slot plate 101, pushing the tightening plate 103 and the tightening ring 104 to move, so that the two ends of the test can be clamped.

[0037] Then, the brine is drawn from the inside of the shelf 2 by the pump 121 and injected into the atomizing nozzle 123. The brine is atomized in the chamber 1 and comes into contact with the test item to achieve the test. During the test, the first active bevel gear 8 is rotated by starting the dual-head motor 7. The first active bevel gear 8 then drives the rotating rod 4 and the first clamping ring 5 to rotate, which can flip the clamped item so that different parts of the surface can be uniformly corroded by the salt spray, thus improving the accuracy of the atomization test.

[0038] While the dual-head motor 7 rotates, it drives the second driving gear 116 and the second driven gear 115 to rotate, which in turn drives the worm gear 114 to rotate the worm wheel 113 and the stirring rod 111. This allows the stirring blade 112 to stir the brine inside the shelf 2, making the salt more evenly distributed in the water, ensuring a consistent solution concentration, reducing static sedimentation, and improving the atomization effect. All components inside this device are made of corrosion-resistant materials and are regularly maintained.

[0039] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
