DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0034] As Figure 1-6 shown, a light aging acceleration test device according to an embodiment of the present utility model includes a base body 1, a mounting table 2, a storage rack 3, a first mounting rack 4 and a reflector 5. The mounting table 2 is connected to the base body 1. The mounting table 2 has a mounting surface 21 facing away from the base body 1, and the mounting surface 21 is arc-shaped. The storage rack 3 includes a connecting portion 31 and a storage portion 32. The storage portion 32 is located on the side of the mounting table 2 away from the base body 1 and faces the mounting surface 21. The storage portion 32 is used for placing the materials to be tested. The connecting portion 31 connects the storage portion 32 and the mounting table 2. There are multiple first mounting racks 4. The multiple first mounting racks 4 are arranged in a row along the arc-shaped direction of the mounting surface 21. There are two rows of first mounting racks 4 on the mounting surface 21 that are symmetric about the first reference plane A. Each first mounting rack 4 is connected with a reflector 5. Each reflector 5 cooperates to converge light to the storage portion 32. Among them, the first mounting rack 4 includes a first connecting column 41, a second connecting column 42 and a mirror frame 43. The first connecting column 41 and the second connecting column 42 are both arranged on the mounting surface 21, and the length directions of both of them intersect with the mounting surface 21. One end of the mirror frame 43 close to the first reference plane A is movably connected to the first connecting column 41, and the end away from the first reference plane A is movably connected to the second connecting column 42. The length of the second connecting column 42 is adjustable, and the reflector 5 is arranged on the mirror frame 43. Since the length of the second connecting column 42 is adjustable, therefore, by changing the length of the second connecting column 42, the angle of the reflected light of the reflector 5 can be changed, and by changing the angle of the reflected light of the reflector 5, the light concentration magnification of the light aging acceleration test device and the irradiation uniformity of the materials to be tested can be changed, which is more conducive to the progress of the light aging acceleration test.

[0035] As a specific implementation of this embodiment, the first connecting column 41 is hinged to the mirror frame 43, and the second connecting column 42 is connected to the mirror frame 43 in a universal joint manner. By adjusting the length of the second connecting column 42, the mirror frame 43 can rotate towards or away from the first reference plane A around its connection with the first connecting column 41.

[0036] As Figure 6As shown in the figure, the second connecting column 42 includes a first column body 421, a second column body 422 and a connecting member 423. The first column body 421 is arranged on the mounting surface 21. A sliding groove 4211 is provided on the side surface of the first column body 421 facing away from the mounting surface 21. A first connecting hole 4212 communicating with the sliding groove 4211 is provided on the circumferential side surface of the first column body 421. The second column body 422 is inserted into the sliding groove 4211. The second column body 422 is provided with a plurality of second connecting holes 4221 penetrating along its radial direction. The plurality of second connecting holes 4221 are arranged along the axial direction of the second column body 422. The first connecting hole 4212 corresponds to one of the second connecting holes 4221. The connecting member 423 passes through the first connecting hole 4212 and the second connecting hole 4221 corresponding to the first connecting hole 4212, so as to connect the first column body 421 and the second column body 422. Specifically, when the first connecting hole 4212 corresponds to different second connecting holes 4221, the height of the second connecting column 42 is different. Based on this, when it is necessary to adjust the height of the second connecting column 42, the connecting member 423 is removed, and then the second column body 422 is slid in the sliding groove 4211 according to the required height, so as to adjust the first connecting hole 4212 to correspond to one of the second connecting holes 4221. Finally, the connecting member 423 is passed through the first connecting hole 4212 and the corresponding second connecting hole 4221 to connect the first column body 421 and the second column body 422, thereby completing the height adjustment of the second connecting column 42. As a specific implementation of this embodiment, the connecting member 423 includes a bolt and a nut. The bolt passes through the first connecting hole 4212 and the second connecting hole 4221 and is connected to the nut, so as to connect the first column body 421 and the second column body 422.

[0037] In some other embodiments, the first mounting bracket 4 has an even number of columns of more than two columns. Each column of the first mounting brackets 4 is symmetric with each other about the first reference plane A. At this time, the lengths of the first connecting column 41 and the second connecting column 42 are both adjustable. Thus, the angle of the light reflected by the reflector 5 can also be changed. As one implementation manner, both the first connecting column 41 and the second connecting column 42 are electric telescopic rods.

[0038] Such as Figure 3As shown, the mounting surface 21 includes a first mounting sub-surface 211 and a second mounting sub-surface 212. There are multiple first mounting sub-surfaces 211, and the multiple first mounting sub-surfaces 211 are arranged in an arc in a row. There are two columns of first mounting sub-surfaces 211 that are symmetric about the second reference plane B. The second mounting sub-surface 212, the first reference plane A, and the second reference plane B are perpendicular to each other pairwise, and the second mounting sub-surface 212 is located between the two columns of second mounting sub-surfaces 212. In a single row of first mounting sub-surfaces 211, along the direction away from the second reference plane B, the included angle between the first mounting sub-surface 211 and the second mounting sub-surface 212 gradually increases; among them, in a single row of first mounting brackets 4, the first mounting brackets 4 are respectively arranged on the first mounting sub-surface 211 and the second mounting sub-surface 212, and the placement part 32 faces the second mounting sub-surface 212. Specifically, both the first mounting sub-surface 211 and the second mounting sub-surface 212 are planes, and their settings are conducive to the installation of the first mounting seat. The first mounting sub-surfaces 211 arranged in an arc are conducive to the reflector 5 converging light to the placement part 32.

[0039] As Figure 1 shown, the light aging acceleration test device further includes a second mounting bracket 6. There are multiple second mounting brackets 6, and the multiple second mounting brackets 6 are arranged in a row along the arc direction of the mounting surface 21. There is at least one row of second mounting brackets 6 between the two rows of first mounting brackets 4, and each second mounting bracket 6 is provided with a reflector 5; in a single row of second mounting brackets 6, the second mounting brackets 6 are respectively arranged on the first mounting sub-surface 211 and the second mounting sub-surface 212, which is convenient for the installation of the second mounting bracket 6. By setting the second mounting bracket 6 to increase the number of reflectors 5 installed, the light collecting area of the light aging acceleration test device can be increased, which is more conducive to improving the irradiation uniformity of the light aging acceleration test device for the test materials.

[0040] As Figure 1 and Figure 4As shown in the figure, the photoaging acceleration test device has a first direction X, and the first direction X is perpendicular to the first reference plane A; the placement part 32 includes a mounting rod 321, a mounting block 322 and a support rod 323. The mounting rod 321 is connected to the connection part 31, and the length direction of the mounting rod 321 is parallel to the first direction X. The mounting block 322 has a receiving groove 3221, and the notch of the receiving groove 3221 faces the mounting surface 21. The length direction of the support rod 323 is parallel to the first direction X. Support rods 323 are provided on both side surfaces of the receiving groove 3221 along the first direction X. The support rods 323 are located at the notch of the receiving groove 3221, and the mounting rod 321 is located in the receiving groove 3221. One of the support rods 323 is connected to the mounting rod 321. The support rods 323 are spaced apart from the mounting rod 321 and define a receiving space for placing the material to be tested. By using this structure to place the material to be tested, the structure is simple, and the material to be tested is convenient and stable to place. Specifically, the two support rods 323 at the notch of the receiving groove 3221 are spaced apart, and the reflector 5 converges the light onto the material to be tested between the two support rods 323. As a specific implementation of this embodiment, the support rod 323 is connected to the mounting rod 321 through a screw and a nut. A nut is provided between the support rod 323 and the mounting rod 321 to space the support rod 323 and the mounting rod 321 apart. Nuts are provided at both ends of the screw in its length direction to connect the support rod 323 and the mounting rod 321.

[0041] As Figure 1 shown in the figure, the connection part 31 includes a connecting rod 311. In the first direction X, connecting rods 311 are provided at both ends of the mounting table 2. The two ends of the mounting rod 321 are respectively connected to the connecting rods 311 at both ends of the mounting table 2, which can make the placement part 32 stable. The photoaging acceleration test device further includes a fan 7. The fan 7 is provided on one of the connecting rods 311, and a through hole 3111 penetrating along the first direction X is provided on the connecting rod 311. The through hole 3111 is located on the side of the mounting rod 321 close to the mounting table 2, and the air outlet end of the fan 7 faces the through hole 3111. Specifically, the air generated by the operation of the fan 7 blows out from the through hole 3111, and it will pass under the test material. Based on this, the temperature of the test material can be taken away, and based on this, the temperature of the test material can be prevented from being too high, ensuring the normal progress of the test work.

[0042] Furthermore, as Figure 4 shown in the figure, the photoaging acceleration test device further includes a water cooling pipe 8. The water cooling pipe 8 is provided in the receiving groove 3221. Specifically, when the photoaging acceleration test device is working, cold water can circulate through the water cooling pipe 8. Based on this, it can cooperate with the fan 7 to take away the temperature of the test material, prevent the temperature of the test material from being too high, and ensure the normal progress of the test work. As a specific implementation of this embodiment, the water cooling pipe 8 is a serpentine pipe, which extends along the first direction X, and can improve its cooling effect on the test material.

[0043] As Figure 1 shown, the light aging acceleration test device further includes a first spray pipe 9. At least one connecting rod 311 is provided with the first spray pipe 9. The first spray pipe 9 is located on the side of the mounting rod 321 close to the mounting table 2. The spray end of the first spray pipe 9 faces between the two connecting rods 311. The first spray pipe 9 is used for spraying water to change the humidity of the environment where the material to be tested is located. Specifically, based on the setting of the first spray pipe 9, the light aging acceleration test device can perform spraying according to the test needs to simulate the accelerated aging test of the test material under different humidities.

[0044] In practical applications, the light aging acceleration test device works outdoors. The reflector 5 reflects sunlight and converges the sunlight onto the test material on the placement part 32. Based on this, the reflector 5 is prone to dust accumulation. As Figure 1 shown, the light aging acceleration test device further includes a second spray pipe 10. The second spray pipe 10 is located on the side of the mounting table 2 away from the seat body 1. The spray end of the second spray pipe 10 faces the mounting surface 21 directly. The second spray pipe 10 is used for spraying water to clean the dust accumulated on the reflector 5, which can ensure the cleanliness of the reflector 5.

[0045] As Figure 1 and Figure 2 shown, the seat body 1 includes a base 11, a first driving member 12, a mounting column 13 and a second driving member 14. The first driving member 12 is arranged on the seat body 1. The mounting column 13 is arranged vertically, and its bottom is connected to the first driving member 12. The second driving member 14 is arranged on the top of the mounting column 13. The mounting table 2 is connected to the second driving member 14. The first driving member 12 is used to drive the mounting column 13 to rotate around its axis. The second driving member 14 is used to drive the mounting table 2 to rotate around the first axis. The first axis is perpendicular to the axis of the mounting column 13. In practical applications, the attitude of the light aging acceleration test device can be adjusted by the first driving member 12 and the second driving member 14 so that the reflector 5 faces the sun, which is beneficial to the reflector 5 reflecting sunlight. In addition, a tracking sensor and an illuminance sensor can be set to cooperate with the first driving member 12 and the second driving member 14 to enable the light aging acceleration test device to automatically track the sun. As a specific implementation of this embodiment, the first driving member 12 is a slewing drive device, and the second driving member 14 includes a motor with a brake.

[0046] The water supply device for supplying water to the first spray pipe 9 and the second spray pipe 10, and the second spray pipe 10 can be connected to the first driving member 12 through a connecting structure. Under the action of the first driving member 12, the first spray pipe 9, the second spray pipe 10 and the water storage device also rotate with the mounting column 13; or the first spray pipe 9 is detachably connected, and the second spray pipe 10 is independently arranged. When the mounting table 2 needs to adjust its attitude, the first spray pipe 9 is removed from the connecting rod 311. The present invention does not limit this.

[0047] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
