Description

Technical Field

[0001] This invention relates to the field of curtain wall profile testing technology, and in particular to a salt spray testing device and method for curtain wall profiles. Background Technology

[0002] Salt spray testing is an environmental test that uses artificially simulated salt spray conditions created by salt spray testing equipment to assess the corrosion resistance of products or metallic materials. It is divided into two main categories: natural environment exposure testing and artificial accelerated simulated salt spray environment testing. Artificial simulated salt spray environment testing uses a testing device with a certain volume—a salt spray test chamber—to artificially create a salt spray environment within its volume to assess the product's salt spray corrosion resistance.

[0003] In the existing technology, in order to conduct durability tests on curtain wall performance, salt spray tests are conducted on curtain wall profiles. However, the scenarios simulated by existing salt spray test devices are quite different from actual usage conditions. For example, the test scenarios are mostly static, while the actual scenarios are more complex, resulting in poor accuracy and effectiveness of the test results. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of poor salt spray test results for curtain wall profiles in the prior art, and to propose a salt spray test device and test method for curtain wall profiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A salt spray testing device for curtain wall profiles includes an annular platform and an annular groove disposed at the upper end of the annular platform. An annular plate is rotatably connected to the upper end of the annular groove. A salt spray generator is fixedly installed at the upper end of the annular plate, and the output end of the salt spray generator extends into the annular groove. A driving part for driving the annular plate to rotate is provided on the annular platform. A plurality of circumferentially distributed circular holes are disposed at the upper end of the annular plate. A turntable is rotatably connected to each of the plurality of circular holes. An inclined insertion hole is provided on each of the plurality of turntables. An automatic deflection mechanism for driving the turntables to rotate forward and backward is provided on the annular plate.

[0007] In order to drive the annular plate to rotate in the annular groove, preferably, the driving unit includes a drive motor fixedly installed on the outer wall of the annular platform, a drive gear fixedly installed on the output shaft of the drive motor, and an annular gear meshing with the drive gear fixedly installed on the annular plate.

[0008] To drive the curtain wall profiles to reciprocate, preferably, the automatic deflection mechanism includes a support fixedly connected to the annular plate, a rotating rod rotatably connected to the support, wherein a worm gear and a driven gear are fixedly installed at both ends of the rotating rod, and a worm wheel meshing with the worm gear is fixedly installed on the outer wall of the turntable; a first arc gear and a second arc gear are fixedly installed on the inner wall of the annular platform through a bracket, the teeth of the first arc gear and the second arc gear have opposite directions, and both the first arc gear and the second arc gear mesh with the driven gear.

[0009] To make the curtain wall profile more stable, preferably, the inner wall of the upper port of the socket is provided with a groove of the same width, and a sliding plate is slidably connected in the groove, wherein the sliding plate and the inner wall of the groove are elastically connected by a retaining spring.

[0010] To facilitate pushing the slide plate 9, a push handle is fixedly installed at the upper end of the slide plate, and a sealing strip is provided on the outer wall of the slide plate.

[0011] To simulate a sandstorm environment, preferably, the lower end of the turntable is fixedly connected to two symmetrically arranged side plates, and a sliding rod is fixedly connected between the two side plates. The sliding rod is parallel to the insertion hole, and a slider is slidably connected to the outer wall of the sliding rod. The lower end of the slider is fixedly connected to a vertical tube, and a brush is fixedly installed on the outer wall of the vertical tube.

[0012] To blow air onto the curtain wall profile, a telescopic airbag is further fixedly installed between the slider and one of the side plates. Multiple nozzles are also installed on the outer wall of the vertical tube. The telescopic airbag is fixedly connected to and communicates with the vertical tube through a connecting pipe. A one-way valve is fixedly installed on each nozzle and the lower end of the vertical tube.

[0013] To further enable the curtain wall profile to undergo multiple annular tests at once, the vertical pipe is provided with a sweeping section, a mixing section and a rinsing section from top to bottom. The sweeping section and the mixing section are each equipped with a brush, and the mixing section and the rinsing section are each equipped with a nozzle. The bottom of the annular groove is filled with rinsing fluid.

[0014] To facilitate the replacement of the flushing fluid in the annular tank, the outer wall of the annular platform is further fixedly connected to an inlet pipe extending into the annular tank, and the bottom of the annular platform is fixedly connected to a drain pipe extending into the annular tank.

[0015] A salt spray test method for curtain wall profiles, the operation steps are as follows:

[0016] Step 1: When using the device, insert the curtain wall profile to be tested into the socket, and then start the salt spray generator and drive motor;

[0017] Step 2: The ring plate sweeps the curtain wall profiles in the salt spray environment;

[0018] Step 3: When it is necessary to adjust the airflow force on the curtain wall profile, adjust the operating power of the drive motor;

[0019] Step 4: As the driven gear slides past the first arc gear and the second arc gear in sequence, the turntable will deflect in the forward direction and then in the reverse direction in sequence.

[0020] Step 5: Under the action of centrifugal force, the slider drives the brush to sweep across the outer wall of the curtain wall profile, simulating manual cleaning of the curtain wall and sand and dust sliding across the curtain wall;

[0021] Step 6: When the test is completed, turn off the salt spray generator and drive motor, and pull the curtain wall profile out of the socket.

[0022] Compared with the prior art, the present invention provides a salt spray testing device for curtain wall profiles, which has the following beneficial effects:

[0023] 1. The salt spray testing device for curtain wall profiles uses a drive motor to rotate an annular plate, which in turn causes the curtain wall profiles to sweep in a salt spray environment. This ensures that the gas in the salt spray environment comes into full contact with the surface of the curtain wall profiles, guaranteeing the test results. Furthermore, the circumferentially sweeping curtain wall profiles also ensure that the gas in the salt spray environment within the annular groove is fully mixed, further guaranteeing the test results. On the other hand, the flowing airflow in the salt spray environment also simulates the wind blowing effect on the curtain wall profiles in actual use, significantly improving the test results.

[0024] 2. The salt spray test device for this curtain wall profile uses a turntable that rotates in the forward and reverse directions in sequence as the passive gear slides through the first and second arc gears. This simulates the curtain wall profile being subjected to salt spray blowing from different directions, making the test process more accurate and ensuring the accuracy of the test results.

[0025] 3. The salt spray test device for this curtain wall profile uses a rotating annular plate to drive the turntable to sweep around the circumference. The slider will slide towards one of the side plates under the action of centrifugal force, thereby driving the brush on the vertical tube to sweep across the outer wall of the curtain wall profile, thus simulating manual cleaning of the curtain wall and wind and sand sliding across the curtain wall, further improving the accuracy and effect of the curtain wall profile test.

[0026] 4. The salt spray testing device for this curtain wall profile uses a telescopic airbag that, when compressed, releases the absorbed salt spray gas into the vertical pipe and then sprays it onto the outer wall of the curtain wall profile from the nozzle on the outer wall of the vertical pipe. This blows off the particulate matter generated after the reaction on the outer wall of the curtain wall profile and allows the salt spray gas to come into more thorough contact with the curtain wall profile, further improving the test results.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example 1:

[0038] Reference Figures 1-7 A salt spray testing device for curtain wall profiles includes an annular platform 1 and an annular groove 2 disposed at the upper end of the annular platform 1. An annular plate 3 is rotatably connected to the upper end of the annular groove 2. A salt spray generator 5 is fixedly installed at the upper end of the annular plate 3. The output end of the salt spray generator 5 extends into the annular groove 2. The annular platform 1 is provided with a driving part for driving the annular plate 3 to rotate. Multiple circumferentially distributed circular holes 4 are disposed at the upper end of the annular plate 3. A turntable 6 is rotatably connected to each of the multiple circular holes 4. Each of the multiple turntables 6 is provided with an inclined insertion hole 7. The annular plate 3 is provided with an automatic deflection mechanism for driving the turntables 6 to rotate forward and backward.

[0039] During use, the curtain wall profile to be tested is inserted into the socket 7. Then, the salt spray generator 5 is activated, and the drive unit rotates the annular plate 3 at the upper end of the annular groove 2. This causes the curtain wall profile in the socket 7 to sweep circumferentially within the annular groove 2, thus allowing the curtain wall profile to sweep in the salt spray environment. This ensures that the gas in the salt spray environment fully contacts the surface of the curtain wall profile, guaranteeing the test effect. Furthermore, the circumferentially sweeping curtain wall profile also ensures that the salt spray environment and gas in the annular groove 2 are fully mixed, further guaranteeing the test effect. On the other hand, the flowing salt spray environment airflow also simulates the wind blowing effect on the curtain wall profile in actual use, significantly improving the test effect. During this period, the automatic deflection mechanism drives the turntable 6 to deflect forward and backward sequentially, thus simulating the salt spray blowing from different directions on the curtain wall profile, making the test process more accurate and ensuring the accuracy of the test results.

[0040] Furthermore, the inner wall of the upper port of the socket 7 is provided with a groove 8 of the same width, and a sliding plate 9 is slidably connected in the groove 8. The sliding plate 9 and the inner wall of the groove 8 are elastically connected by a retaining spring 10. Before the curtain wall profile is inserted into the socket 7, the sliding plate 9 is pushed away from the port of the socket 7, then the curtain wall profile is inserted into the socket 7, and finally the sliding plate 9 is pushed in. The sliding plate 9 will then press against the outer wall of the curtain wall profile under the action of the retaining spring 10, thereby making the curtain wall profile more stable. When the curtain wall profile is not inserted into the socket 7, the sliding plate 9 will block the socket 7 under the action of the retaining spring 10, thereby preventing the salt spray gas in the annular groove 2 from flowing out of the socket 7 and protecting the surrounding environment.

[0041] Furthermore, a push handle 11 is fixedly installed on the upper end of the skateboard 9, and a sealing strip is provided on the outer wall of the skateboard 9. Pushing the skateboard 9 with the push handle 11 can be more effortless and convenient, and the sealing strip can improve the sealing between the skateboard 9 and the socket 7.

[0042] Example 2:

[0043] Reference Figure 1 , Figure 2 , Figure 5 as well as Figure 6 The implementation is basically the same as in Example 1, but further, a specific implementation scheme of the drive unit is disclosed.

[0044] The drive unit includes a drive motor 12 fixedly mounted on the outer wall of the annular plate 1, a drive gear 13 fixedly mounted on the output shaft of the drive motor 12, and an annular gear 14 fixedly mounted on the annular plate 3 and meshing with the drive gear 13.

[0045] During use, the curtain wall profile to be tested is inserted into the socket 7, and then the salt spray generator 5 and drive motor 12 are started. The salt spray generator 5 generates a salt spray environment in the annular groove 2, while the drive motor 12 drives the annular gear 14 to rotate through the drive gear 13. The annular gear 14 drives the annular plate 3 to rotate at the upper end of the annular groove 2, thereby causing the curtain wall profile in the socket 7 to sweep circumferentially in the annular groove 2. This sweeping motion of the curtain wall profile in the salt spray environment ensures that the gas in the salt spray environment comes into full contact with the surface of the curtain wall profile, guaranteeing the test effect. Furthermore, the circumferentially sweeping curtain wall profile also ensures that the salt spray environment in the annular groove 2 is fully mixed with the gas, further guaranteeing the test effect. On the other hand, the flowing salt spray environment airflow also simulates the wind blowing effect on the curtain wall profile in actual use, significantly improving the test effect.

[0046] Example 3:

[0047] Reference Figures 1-3 , Figures 5-6Similar to Example 2, but further, a specific implementation scheme for the automatic deflection mechanism is disclosed.

[0048] The automatic deflection mechanism includes a support 15 fixedly connected to the annular plate 3, a rotating rod 16 rotatably connected to the support 15, wherein a worm gear 17 and a driven gear 18 are fixedly installed at both ends of the rotating rod 16 respectively, and a worm wheel 19 meshing with the worm gear 17 is fixedly installed on the outer wall of the turntable 6; a first arc gear 21 and a second arc gear 22 are fixedly installed on the inner wall of the annular platform 1 through a bracket 34, the teeth of the first arc gear 21 and the second arc gear 22 are opposite in direction, and both the first arc gear 21 and the second arc gear 22 are engaged with the driven gear 18;

[0049] When the annular plate 3 rotates, it also drives the passive gear 18 to sweep around its circumference. The passive gear 18 will mesh with the first arc gear 21 and the second arc gear 22 in sequence. When the passive gear 18 meshes with the first arc gear 21, the passive gear 18 will rotate forward, thereby driving the driving gear 13 to rotate forward. The driving gear 13 will then drive the worm gear 17 to rotate forward through the rotating rod 16. The worm gear 17 will drive the turntable 6 to rotate forward through the worm wheel 19. The turntable 6 will cause the curtain wall profile to deflect. When the passive gear 18 meshes with the second arc gear 22, the passive gear 18 will rotate in reverse, thereby driving the turntable 6 to deflect in the opposite direction. Thus, as the passive gear 18 slides past the first arc gear 21 and the second arc gear 22 in sequence, the turntable 6 will deflect in the forward and reverse directions in sequence, thereby simulating that the curtain wall profile is subjected to salt spray blowing from different directions, thus making the test process more accurate and ensuring the accuracy of the test results.

[0050] Example 4:

[0051] Reference Figure 7 It is basically the same as Example 3, but with the addition of a specific implementation plan for simulating sandstorms.

[0052] The lower end of the turntable 6 is fixedly connected to two symmetrically arranged side plates 23. A slide rod 24 is fixedly connected between the two side plates 23. The slide rod 24 is parallel to the insertion hole 7. A slider 25 is slidably connected to the outer wall of the slide rod 24. A vertical tube 26 is fixedly connected to the lower end of the slider 25. A brush 27 is fixedly installed on the outer wall of the vertical tube 26.

[0053] When the annular plate 3 rotates, it drives the turntable 6 to sweep around its circumference. The turntable 6 then drives the slider 25 to sweep synchronously. The slider 25 slides towards one of the side plates 23 under the action of centrifugal force, thereby driving the lower vertical tube 26 to slide synchronously. The vertical tube 26 drives the brush 27 on the outer wall to sweep across the outer wall of the curtain wall profile, thereby simulating manual cleaning of the curtain wall and wind and sand sliding across the curtain wall, further improving the accuracy and effect of the curtain wall profile test. When the turntable 6 deflects in the opposite direction, the slider 25 slides towards the other side plate 23 under the action of centrifugal force. Thus, the reciprocating deflection of the turntable 6 causes the vertical tube 26 to slide back and forth, thereby driving the brush 27 to slide back and forth on the outer wall of the curtain wall profile.

[0054] Example 5:

[0055] Reference Figure 7 The implementation is basically the same as in Example 1, but with a further addition of a specific implementation plan for blowing air onto the curtain wall profile.

[0056] A telescopic airbag 30 is fixedly installed between the slider 25 and one of the side plates 23. Multiple nozzles 28 are also installed on the outer wall of the vertical tube 26. The telescopic airbag 30 is fixedly connected to and communicates with the vertical tube 26 through the connecting pipe 31. A one-way valve 29 is fixedly installed on each nozzle 28 and the lower end of the vertical tube 26.

[0057] As the slider 25 slides back and forth, it intermittently squeezes and stretches the telescopic airbag 30. When stretched, the telescopic airbag 30 draws in the vertical pipe 26 through the connecting pipe 31. The vertical pipe 26 then draws in the salt spray gas from the annular groove 2. When the telescopic airbag 30 is squeezed, it discharges the drawn salt spray gas into the vertical pipe 26 and then sprays it from the nozzle 28 on the outer wall of the vertical pipe 26 onto the outer wall of the curtain wall profile. This blows off the particulate matter generated after the reaction on the outer wall of the curtain wall profile and allows the salt spray gas to come into more full contact with the curtain wall profile, further improving the test results.

[0058] Furthermore, the vertical pipe 26 is provided with a sweeping section 35, a mixing section 36 and a rinsing section 20 from top to bottom. The sweeping section 35 and the mixing section 36 are each provided with a brush 27, and the mixing section 36 and the rinsing section 20 are each provided with a nozzle 28. The bottom of the annular groove 2 is filled with rinsing liquid.

[0059] Because the bottom of the annular groove 2 is equipped with flushing fluid, when the vertical pipe 26 draws in air, it will draw in the flushing fluid and spray it onto the curtain wall profile through the nozzle 28 for flushing, thereby simulating the effects of rain and artificial washing. Since the vertical pipe 26 is equipped with a sweeping section 35, a mixing section 36, and a flushing section 20 from top to bottom, the curtain wall profile will be subjected to different test processes. For example, in the sweeping section 35, the curtain wall profile will only be brushed by the brush 27, thus simply simulating the erosion of the curtain wall profile by wind and sand. In the flushing section 20, the curtain wall profile will only be blown by the nozzle 28, thus simply simulating simple flushing. In the mixing section 36, the curtain wall profile will be both swept and flushed, allowing the curtain wall profile to undergo simulated tests of different environments at once, making the test process and results more diverse.

[0060] Furthermore, the outer wall of the annular platform 1 is fixedly connected to an inlet pipe 33 extending into the annular groove 2, which allows for easy addition of rinsing liquid to the annular groove 2. The bottom of the annular platform 1 is fixedly connected to a drain pipe 32 extending into the annular groove 2, which facilitates the discharge of wastewater from the annular groove 2.

[0061] A salt spray test method for curtain wall profiles, the operation steps are as follows:

[0062] Step 1: When using, insert the curtain wall profile to be tested into the socket 7, and then start the salt spray generator 5 and the drive motor 12;

[0063] Step 2: The annular plate 3 causes the curtain wall profiles to sweep in the salt spray environment;

[0064] Step 3: When it is necessary to adjust the airflow force on the curtain wall profile, adjust the operating power of the drive motor 12;

[0065] Step 4: As the driven gear 18 slides past the first arc gear 21 and the second arc gear 22 in sequence, the turntable 6 will deflect in the forward direction and then in the reverse direction in sequence.

[0066] Step 5: Under the action of centrifugal force, slider 25 drives brush 27 to sweep across the outer wall of the curtain wall profile, simulating manual cleaning of the curtain wall and sand and dust sliding across the curtain wall;

[0067] Step 6: When the test is completed, turn off the salt spray generator 5 and the drive motor 12, and pull the curtain wall profile out of the socket 7.

[0068] This salt spray testing device for curtain wall profiles involves inserting the curtain wall profile to be tested into the insertion hole 7, then activating the salt spray generator 5 and drive motor 12. The salt spray generator 5 creates a salt spray environment within the annular groove 2, while the drive motor 12 drives the annular gear 14 to rotate via the drive gear 13. The annular gear 14 then drives the annular plate 3 to rotate at the upper end of the annular groove 2, causing the curtain wall profile in the insertion hole 7 to sweep circumferentially within the annular groove 2. This sweeping motion ensures that the gas in the salt spray environment fully contacts the surface of the curtain wall profile, guaranteeing the test results. Furthermore, the circumferentially sweeping curtain wall profile also thoroughly mixes the salt spray environment with the gas within the annular groove 2, further ensuring the test results. On the other hand, the flowing salt spray environment also simulates the wind blowing effect experienced by the curtain wall profile in actual use, significantly improving the test results.

[0069] When the annular plate 3 rotates, it also drives the passive gear 18 to sweep around its circumference. The passive gear 18 will mesh with the first arc gear 21 and the second arc gear 22 in sequence. When the passive gear 18 meshes with the first arc gear 21, the passive gear 18 will rotate forward, thereby driving the driving gear 13 to rotate forward. The driving gear 13 will then drive the worm gear 17 to rotate forward through the rotating rod 16. The worm gear 17 will drive the turntable 6 to rotate forward through the worm wheel 19. The turntable 6 will cause the curtain wall profile to deflect. When the passive gear 18 meshes with the second arc gear 22, the passive gear 18 will rotate in reverse, thereby driving the turntable 6 to deflect in the opposite direction. Thus, as the passive gear 18 slides past the first arc gear 21 and the second arc gear 22 in sequence, the turntable 6 will deflect in the forward and reverse directions in sequence, thereby simulating that the curtain wall profile is subjected to salt spray blowing from different directions, thus making the test process more accurate and ensuring the accuracy of the test results.

[0070] When the annular plate 3 rotates, it drives the turntable 6 to sweep around its circumference. The turntable 6 then drives the slider 25 to sweep synchronously. The slider 25 slides towards one of the side plates 23 under the action of centrifugal force, thereby driving the lower vertical tube 26 to slide synchronously. The vertical tube 26 drives the brush 27 on the outer wall to sweep across the outer wall of the curtain wall profile, thereby simulating manual cleaning of the curtain wall and wind and sand sliding across the curtain wall, further improving the accuracy and effect of the curtain wall profile test. When the turntable 6 deflects in the opposite direction, the slider 25 slides towards the other side plate 23 under the action of centrifugal force. Thus, the reciprocating deflection of the turntable 6 causes the vertical tube 26 to slide back and forth, thereby driving the brush 27 to slide back and forth on the outer wall of the curtain wall profile.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
