Currently, the more common test method is to intersperse the salt water spraying condition in the salt spray condition.

[0003] The existing invention patent application with the publication number CN116067866A discloses a fuel cell salt spray test device and a test method. The test device includes a test chamber and a salt water supply device; a salt spray evaporation device, a heating device, a salt spray evaporation controller, a salt content sensor, and a temperature controller are provided on the test chamber; the salt water supply device is connected to the salt spray evaporation controller, the salt spray evaporation controller and the salt content sensor are electrically connected to each other, and the salt spray evaporation controller and the salt content sensor are respectively electrically connected to the salt water supply device. The device and test method of this invention include the corrosive tests on the whole fuel cell engine system during operation and in a static environment, and also include the tests on engine components and their materials; the corrosive environment can be simulated by spraying salt spray and water vapor, and the tests can be carried out under operating conditions or static conditions.

[0004] The inventor believes that there are differences in the external dimensions of different automotive batteries, and there are also occasions where the battery is tested together with the external structure. When spraying salt water on it, it is difficult to completely cover the surface of the component. If the methods of excessive spraying and large-area spraying are adopted, a large amount of waste will be caused. Summary of the Invention

[0005] This application provides a salt spray and water spray bench. By providing a plurality of adjustable nozzles, it is convenient to adjust the landing points of the salt water spray to adapt to the shape of the test piece, avoid the extensive water spraying method, and reduce the waste of salt water.

[0006] A salt spray and water spray bench provided by this application adopts the following technical solutions: A salt spray and water spray bench includes a frame, a loading rack for placing the test piece. A plurality of bases are provided on the frame. A first cylinder is rotatably installed on the base. A nozzle is fixed to the outer wall of the first cylinder. The nozzle is communicated with a water pipe. A support member is fixed to the frame. The first cylinder leans against the support member obliquely; the base is rotatably connected to the frame. The base is drivingly connected with a gear. A rack is slidably connected to the frame. The rack is used to mesh with the gear.

[0007] By adopting the above technical solution, in the salt spray chamber, the water spraying operation is interspersed in the salt spray working condition, and the water spraying operation is generated by the nozzle. Multiple nozzles can provide more water spraying positions, improve the salt water coverage rate, and can perform fixed-point water spraying on the required positions, avoiding waste caused by excessive spraying and large-area spraying. By controlling the expansion and contraction of the first cylinder, the height position of the corresponding nozzle can be adjusted, so as to adjust the spraying position and change the landing point of the salt water. The orientation of the nozzle can be adjusted by rotating the base, so that the nozzle faces the part to be sprayed with water. When the rack is pulled to slide back and forth, the engaged gear rotates, thereby driving the corresponding nozzle to swing, so as to expand the salt water spraying range.

[0008] Optionally, a sliding connection is established between the gear and the base through a keyway structure. After the gear slides upward, it disengages from the rack. A spring buckle is provided on the inner wall of the gear, and a slot for the spring buckle to engage is provided on the outer wall of the base. The height position of the slot is higher than that of the rack.

[0009] By adopting the above technical solution, after the gear is slid upward, the spring buckle is inserted into the slot, so as to maintain the gear at this height position. After the gear is separated from the rack, the base can be independently rotated, so as to adjust the initial orientation position of the corresponding nozzle. After the gear is slid downward, it meshes with the rack again. The corresponding gear and rack can also be disengaged, so as to avoid the swing angle of the nozzle and improve the spraying effect on specific positions.

[0010] Optionally, a second cylinder is fixed to the frame, and the telescopic end of the second cylinder is fixed to the rack.

[0011] By adopting the above technical solution, the second cylinder drives the rack to move back and forth, and then drives the engaged gear to rotate.

[0012] Optionally, the water pipe is communicated with the water tank through a pump.

[0013] Optionally, the support member includes a support rod slidably connected to the frame and a contact rod for contacting the first cylinder. The contact rod has a bent section.

[0014] By adopting the above technical solution, through the bent contact rod, the adjustable range of the nozzle spraying is further improved. When the contact rod slides along with the support rod, the first cylinder swings along with the bent contact rod, so that the spraying angle of the nozzle swings.

[0015] Optionally, a third cylinder is fixed to the frame, and the telescopic end of the third cylinder is fixed to the support rod.

[0016] By adopting the above technical solution, the third cylinder is used to drive the support rod to move back and forth.

[0017] Optionally, the contact rod includes a plurality of sleeve rods and a plurality of sliding rods. Sleeve rods are correspondingly arranged at both ends of each sliding rod. The sleeve rods are slidably connected to the sliding rods. A plurality of adjusting rods are threadedly connected to the support rod. A top head is rotatably connected to the end of each adjusting rod. The sleeve rod is rotatably connected to the top head.

[0018] By adopting the above technical solution, by rotating the adjusting rod, the distance between the top head and the support rod is adjusted through the threaded connection effect. After the distance between the top head and the support rod changes, an adaptive sliding occurs between the sleeve rod and the sliding rod, and an adaptive rotation occurs between the sleeve rod and the top head, thereby changing the bending shape of the contact rod, customizing the swing angle range of the nozzle, making it adapt to the shape of a specific test piece, and improving the adaptability.

[0019] Optionally, the support rod is provided with an adjusting hole for the adjusting rod to pass through. A screwing head is fixed to the end of the adjusting rod away from the top head. The screwing head is located outside the adjusting hole.

[0020] By adopting the above technical solution, the adjusting rod is rotated by the screwing head.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Multiple nozzles can provide more water spraying positions, improve the salt water coverage rate, and can perform fixed-point water spraying at the required positions, avoiding waste caused by excessive spraying and large-area spraying; 2. By controlling the telescoping of the first cylinder, the height position of the corresponding nozzle can be adjusted, thereby adjusting the spraying position and changing the landing point of the salt water; 3. The angle of the nozzle is adjustable in multiple directions and can achieve automatic swinging, improving the spraying range. The swinging position and range can also be adjusted, improving the adaptability to the test piece. Description of the Drawings

Detailed implementation mode

[0024] The following further details the present application in conjunction with the attached drawings.

[0025] Embodiment 1

[0026] Referring to Figure 1 and Figure 2 This embodiment discloses a salt spray water spraying bench, including a frame 1 and a material holding rack 2 for placing test pieces. A plurality of bases 3 are provided on the frame 1. A first cylinder 4 is rotatably installed on the base 3, and a nozzle 5 is fixed to the outer wall of the first cylinder 4. The frame 1 is fixed with a support member 6, and the first cylinder 4 leans against the support member 6 obliquely. The brine sprayed from the nozzle 5 is sprayed on the test pieces on the material holding rack 2 in a parabolic manner. When the first cylinder 4 expands and contracts, the height position of the nozzle 5 can be adjusted, thereby adjusting the spraying position.

[0027] The telescopic end of the first cylinder 4 is arranged downward, and the telescopic end of the first cylinder 4 is hinged to the base 3. The first cylinder 4 contacts the support member 6 through the side wall of the cylinder body.

[0028] 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, and the water pipe 51 is connected to a water tank through a pump. Each water pipe 51 is provided with an electromagnetic valve for controlling the on-off of the brine in the corresponding water pipe 51.

[0029] The base 3 is rotatably connected to the frame 1, and the rotation plane of the base 3 is a horizontal plane. The base 3 is drivingly connected to a gear 31, and a rack 11 is slidably connected to the frame 1. The rack 11 is used to mesh with the gear 31. Specifically, a sliding connection is established between the gear 31 and the base 3 through a keyway structure. After the gear 31 slides upward, it disengages from the rack 11. A spring buckle 32 is provided on the inner wall of the gear 31, and a card slot 33 for the spring buckle 32 to be snapped into is provided on the outer wall of the base 3. The height position of the card slot 33 is higher than that of the rack 11.

[0030] By sliding the gear 31 upward, the spring buckle 32 is inserted into the card slot 33, thereby maintaining the gear 31 at this height position, preventing the gear 31 from moving downward spontaneously, and keeping the gear 31 disengaged from the rack 11. Through this structure, personnel can select the number and position of the gears 31 driven by the rack 11. For the position of the nozzle 5 that does not need to rotate and spray, the gear 31 corresponding to the nozzle 5 can be disengaged from the rack 11.

[0031] The frame 1 is fixed with a second cylinder 12. The telescopic end of the second cylinder 12 is fixed to the rack 11. By driving the rack 11 to move back and forth through the second cylinder 12, the engaged gear 31 is driven to rotate, thereby driving the base 3 and the nozzle 5 to rotate by an angle, expanding the spraying range. The cylinder body of the second cylinder 12 is located outside the salt spray box, and the piston rod of the second cylinder 12 penetrates into the salt spray box and is fixed to the rack 11.

[0032] 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 the salt spray box 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, so as to adjust the initial orientation position of the corresponding nozzle 5, and the gear 31 can be 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 meshing gear 31 to rotate, thereby driving the corresponding nozzle 5 to swing the angle, thereby expanding the salt water spraying range; for the position that needs to be sprayed intensively, the corresponding gear 31 can be disengaged from the rack 11, thereby avoiding the nozzle 5 from swinging the angle and improving the spraying effect at the 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.

[0033] The salt spray chamber is equipped with an atomizing nozzle, and the salt spray environment in the salt spray chamber is generated by the atomizing nozzle. The entire test device requires a water spraying stand to cooperate with the salt spray chamber, and the water spraying condition is interspersed with the specified salt spray condition, and the water spraying condition is generated by nozzle 5.

[0034] Embodiment 2

[0035] Reference Figure 3 and Figure 4 , a salt spray water spraying stand, the difference between the second embodiment and the first embodiment is that: the support member 6 includes a support rod 61 slidably connected to the frame 1, and a contact rod 62 for contacting the cylinder 1 4, and the contact rod 62 has a bent section. When the cylinder 1 4 leans against the contact rod 62, the bent contact rod 62 makes the multiple cylinders 1 4 present different tilt angles.

[0036] 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.

[0037] The contact rod 62 includes a plurality of sleeve rods 71 ​​and a plurality of slide rods 72. The two ends of the slide rod 72 correspond to the sleeve rods 71. The sleeve rods 71 ​​are slidably connected to the slide rods 72. The support rod 61 is threaded with a plurality of adjustment rods 7. The ends of the adjustment rods 7 are rotatably connected to the top heads 73. The sleeve rods 71 ​​are rotatably connected to the top heads 73. The multiple sets of top heads 73, the sleeve rods 71, and the adjustment rods 7 are combined into a curved shape that contacts the cylinder 4. After the distance between the top heads 73 and the support rod 61 changes, an adaptive sliding occurs between the sleeve rods 71 ​​and the slide rods 72, and an adaptive rotation occurs between the sleeve rods 71 ​​and the top heads 73.

[0038] 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 .

[0039] The implementation principle of the second embodiment is as follows: By bending the contact rod 62, the adjustable range of the spraying of the nozzle 5 is further improved. When the contact rod 62 slides, the first cylinder 4 swings in contact with the bent contact rod 62, so that the spraying angle of the nozzle 5 swings. Through the reciprocating telescoping of the third cylinder 63, the nozzle 5 is driven to swing reciprocally, improving the spraying range. By rotating the screw head 70 to drive the adjusting rod 7 to rotate, the adjusting rod 7 adjusts the distance between the top head 73 and the support rod 61 through the thread connection effect, thereby changing the bending shape of the contact rod 62, customizing the swing angle range of the nozzle 5 to adapt to the shape of a specific test piece, and improving the adaptability.

[0040] When the third cylinder 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 first cylinder 4, and thus adjusting the spraying position of the nozzle 5 and changing the landing point of the brine.

[0041] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
