Description

Technical Field

[0001] The present application relates to the technical field of automobile battery testing, and in particular to a salt spray water test bench. Background Art

[0002] In the field of electric vehicles, electric vehicle batteries need to undergo salt spray testing, which simulates a corrosive environment through high salinity and humidity to test the components' waterproofness, corrosion resistance, and rust resistance. The more commonly used testing method is to intersperse salt water spray conditions with salt spray conditions.

[0003] An existing invention patent application with publication number CN116067866A discloses a fuel cell salt spray testing device and method. The testing device comprises a test chamber and a salt water supply device. The test chamber is equipped with a salt spray evaporator, a heating device, a salt spray evaporation controller, a salt content sensor, and a temperature controller. The salt water supply device is connected to the salt spray evaporator, which is electrically connected to the salt spray evaporator and the salt content sensor. The salt spray evaporator and the salt content sensor are each electrically connected to the salt water supply device. The device and testing method encompass corrosion testing of the entire fuel cell engine system during operation and in a static environment, as well as testing of engine components and their materials. Testing can be performed under both operating and static conditions by spraying salt spray and water vapor to simulate a corrosive environment.

[0004] The inventor believes that different car batteries have different external dimensions, and there are also situations where the battery needs to be tested together with the external structure. When spraying salt water on them, it is difficult to completely cover the surface of the components. If excessive spraying and large-area spraying are used, a lot of waste will be caused. Summary of the Invention

[0005] The present application provides a salt spray water stand, which is equipped with multiple adjustable nozzles to facilitate the adjustment of the landing point of the salt water spray to adapt to the shape of the test piece, avoid extensive water spraying methods, and reduce salt water waste.

[0006] The present application provides a salt spray water spraying stand, which adopts the following technical solutions:

[0007] A salt spray water spray stand comprises a frame and a material holding rack for placing test pieces. The frame is provided with multiple bases, a cylinder 1 is rotatably mounted on the base, a nozzle is fixed to the outer wall of the cylinder 1, and the nozzle is connected to a water pipe. A support is fixed to the frame, and the cylinder 1 leans against the support at an angle. The base is rotatably connected to the frame, the base is transmission-connected to a gear, and the frame is slidably connected to a rack, and the rack is used to mesh with the gear.

[0008] By adopting the above technical solution, a water spraying condition is interspersed with a salt spray condition within a salt spray chamber, and the water spraying condition is generated by a nozzle. Multiple nozzles can provide more water spraying positions, improve the salt water coverage rate, and can spray water at the required locations, avoiding waste caused by excessive spraying and large-area spraying. By controlling the extension and contraction of cylinder 1, the height position of the corresponding nozzle can be adjusted, thereby adjusting the spraying position and changing the landing point of the salt water. The orientation of the nozzle can be adjusted by rotating the base, so that the nozzle is facing the area where water is to be sprayed. When the rack is pulled back and forth, the meshing gear rotates, which drives the corresponding nozzle to swing at an angle, thereby expanding the salt water spray range.

[0009] Optionally, a sliding connection is established between the gear and the base through a keyway structure, and the gear disengages from the rack after sliding upward. The inner wall of the gear is provided with a spring clip, and the outer wall of the base is provided with a slot for the spring clip to engage, and the height of the slot is higher than the rack.

[0010] By adopting this technical solution, after sliding the gear upward, the spring clip engages the slot, maintaining the gear at that height. After the gear is separated from the rack, the base can be rotated independently to adjust the initial orientation of the corresponding nozzle. Sliding the gear downward re-engages the rack. The corresponding gear can also be disengaged from the rack, preventing the nozzle from swinging at an angle and improving the spraying effect at a specific location.

[0011] Optionally, a second cylinder is fixed to the frame, and the telescopic end of the second cylinder is fixed to the rack.

[0012] By adopting the above technical solution, the rack is driven to move back and forth by the second cylinder, thereby driving the meshing gear to rotate.

[0013] Optionally, the water pipe is connected to the water tank through a pump.

[0014] Optionally, the support member includes a support rod slidably connected to the frame and a contact rod for contacting the cylinder 1, wherein the contact rod has a bent section.

[0015] By adopting the above technical solution, the adjustable range of the nozzle spraying is further improved by the bent contact rod. When the contact rod slides with the support rod, the cylinder fits the bent contact rod to swing, thereby causing the spraying angle of the nozzle to swing.

[0016] Optionally, a cylinder three is fixed to the frame, and the telescopic end of the cylinder three is fixed to the support rod.

[0017] By adopting the above technical solution, cylinder three is used to drive the support rod to move back and forth.

[0018] Optionally, the contact rod includes multiple sleeve rods and multiple sliding rods, each end of the sliding rod corresponds to a sleeve rod, the sleeve rod is slidingly connected to the sliding rod, multiple adjustment rods are threadedly connected to the support rod, the end of the adjustment rod is rotatably connected to a head, and the sleeve rod is rotatably connected to the head.

[0019] By adopting the above technical solution, the adjusting rod is rotated, and the adjusting rod adjusts the distance between the mandrel and the support rod through the threaded connection. After the distance between the mandrel and the support rod is changed, adaptive sliding occurs between the sleeve rod and the slide rod, and adaptive rotation occurs between the sleeve rod and the mandrel, thereby changing the bending shape of the contact rod and customizing the swing angle range of the nozzle to adapt to the specific test piece shape, thereby improving adaptability.

[0020] Optionally, the support rod is provided with an adjustment hole for the adjustment rod to pass through, and a screw head is fixed to the end of the adjustment rod away from the top head, and the screw head is located outside the adjustment hole.

[0021] By adopting the above technical solution, the adjusting rod is driven to rotate by twisting the head.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Multiple nozzles can provide more spraying positions, improve the brine coverage rate, and can spray water at the required positions to avoid waste caused by excessive spraying and large-area spraying;

[0024] 2. By controlling the extension and contraction of cylinder 1, the height of the corresponding nozzle can be adjusted, thereby adjusting the spraying position and changing the landing point of the salt water;

[0025] 3. The angle of the nozzle can be adjusted in multiple directions and can be automatically swung to increase the spraying range. The position and range of the swing can also be adjusted to improve the adaptability to the test piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 This embodiment discloses a salt spray water spraying stand, comprising a frame 1 and a material holding rack 2 for placing test pieces. Frame 1 is provided with multiple bases 3, rotatably mounted with cylinders 4. Spray heads 5 are fixed to the outer wall of cylinders 4. Support members 6 are fixed to frame 1, and cylinders 4 lean against them at an angle. Salt water sprayed from spray heads 5 is sprayed parabolically onto the test pieces in material holding rack 2. The extension and retraction of cylinders 4 adjust the height of spray heads 5, thereby adjusting the spraying position.

[0034] The telescopic end of the cylinder 1 4 is set downward, the telescopic end of the cylinder 1 4 is hinged to the base 3, and the cylinder 1 4 is in contact with the support member 6 through the side wall of the cylinder body.

[0035] The support member 6 of this embodiment is a rod fixed to the frame 1. The nozzle 5 is connected to a water pipe 51, which is connected to the water tank through a pump. Each water pipe 51 has a corresponding solenoid valve for controlling the flow of brine into the corresponding water pipe 51.

[0036] The base 3 is rotatably connected to the frame 1, with the base 3 rotating about a horizontal plane. A gear 31 is drivingly connected to the base 3, and a rack 11 is slidingly connected to the frame 1. The rack 11 is configured to mesh with the gear 31. Specifically, a keyway structure establishes a sliding connection between the gear 31 and the base 3, allowing the gear 31 to disengage from the rack 11 when it slides upward. A spring clip 32 is provided on the inner wall of the gear 31, and a slot 33 is provided on the outer wall of the base 3 for the spring clip 32 to engage. The slot 33 is positioned higher than the rack 11.

[0037] By sliding the gear 31 upward, the spring clip 32 engages the slot 33, thereby maintaining the gear 31 at that height, preventing the gear 31 from spontaneously moving downward and keeping the gear 31 disengaged from the rack 11. This structure allows the operator to select the number and position of the gears 31 to be rotated by the rack 11. For positions of the nozzle 5 that do not need to rotate for spraying, the corresponding gear 31 can be disengaged from the rack 11.

[0038] Cylinder 2 (12) is fixed to frame 1. The telescopic end of cylinder 2 (12) is fixed to rack 11. Cylinder 2 (12) drives rack 11 back and forth, which in turn drives the meshing gear 31 to rotate, thereby driving the base 3 and nozzle 5 to rotate the angle, expanding the spray range. The cylinder body of cylinder 2 (12) is located outside the salt spray chamber, and the piston rod of cylinder 2 (12) penetrates the salt spray chamber and is fixed to rack 11.

[0039] The implementation principle of a salt spray water spray stand in the embodiment of the present application is as follows: the material rack 2 and the frame 1 are both placed in a salt spray chamber for use, and the test piece is placed on the material rack 2. After the gear 31 is slid upward, the base 3 can be rotated independently, thereby adjusting the initial orientation position of the corresponding nozzle 5, and the gear 31 is slid downward to re-engage with the rack 11. By controlling the reciprocating extension and contraction of the cylinder 2 12, the rack 11 is driven to slide back and forth, thereby driving the meshed gear 31 to rotate, thereby driving the corresponding nozzle 5 to swing angle, thereby expanding the salt water spraying range; for positions that need to be sprayed with emphasis, the corresponding gear 31 can be disengaged from the rack 11, thereby avoiding the nozzle 5 from swinging angle and improving the spraying effect at a specific position. By controlling the extension and contraction of the cylinder 1 4, the height position of the corresponding nozzle 5 can be adjusted, thereby adjusting the spraying position and changing the landing point of the salt water.

[0040] The salt spray chamber is equipped with an atomizing nozzle, which generates the salt spray environment inside the chamber. The entire test device requires a water spray stand to be coordinated with the salt spray chamber. The water spray conditions are interspersed with the specified salt spray conditions. The water spray conditions are generated by nozzle 5.

[0041] Example 2

[0042] Reference Figure 3 and Figure 4 A salt spray water spray stand is provided. Embodiment 2 differs from Embodiment 1 in that a support member 6 includes a support rod 61 slidably connected to the frame 1 and a contact rod 62 for contacting a cylinder 1 (4). The contact rod 62 has a bent section. When a cylinder 1 (4) leans against the contact rod 62, the bent contact rod 62 causes the multiple cylinders 1 (4) to assume different tilt angles.

[0043] The frame 1 is fixed with a cylinder three 63, the cylinder body of the cylinder three 63 is located outside the salt spray chamber, the telescopic end of the cylinder three 63 is fixed to the support rod 61, and the cylinder three 63 is used to drive the support rod 61 to move back and forth.

[0044] The contact rod 62 includes multiple sleeve rods 71 and multiple slide rods 72. Each end of the slide rod 72 has a sleeve rod 71, and the sleeve rods 71 and the slide rods 72 are slidably connected. Multiple adjustment rods 7 are threadedly connected to the support rod 61. The ends of the adjustment rods 7 are rotatably connected to the plugs 73, and the sleeve rods 71 and the plugs 73 are rotatably connected. The multiple sets of plugs 73, sleeve rods 71, and adjustment rods 7 are combined to form a curved shape that contacts the cylinder 4. When the distance between the plugs 73 and the support rod 61 changes, adaptive sliding occurs between the sleeve rods 71 and the slide rods 72, and adaptive rotation occurs between the sleeve rods 71 and the plugs 73.

[0045] The support rod 61 is provided with an adjustment hole 64 for the adjustment rod 7 to pass through. The adjustment hole 64 is a threaded hole. A screw head 70 is fixed to the end of the adjustment rod 7 away from the top head 73 . The screw head 70 is located outside the adjustment hole 64 .

[0046] The operating principle of Example 2 is as follows: The curved contact rod 62 further increases the adjustable spray range of the nozzle 5. When the contact rod 62 slides, the cylinder 1 4 oscillates in alignment with the curved contact rod 62, causing the spray angle of the nozzle 5 to oscillate. The reciprocating extension and contraction of the cylinder 3 63 drives the nozzle 5 to oscillate, increasing the spray range. By rotating the screw 70, the adjustment rod 7 rotates. The adjustment rod 7, through a threaded connection, adjusts the distance between the head 73 and the support rod 61, thereby changing the curved shape of the contact rod 62. This allows the nozzle 5's oscillation range to be customized to suit the specific test piece shape, improving adaptability.

[0047] When the cylinder three 63 stops working, the position of the top head 73 can also be adjusted by rotating the adjusting rod 7, thereby changing the inclination angle of the cylinder one 4, thereby adjusting the spraying position of the nozzle 5 and changing the landing point of the brine.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
