DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides an implementation scheme: in the modern climate environment testing process, when the test box simulates the rain environment, it can often only simulate the rainfall environment of rain, usually using a fixed angle, and cannot effectively simulate the rain incident angle, and cannot truly restore the impact of rain on the reliability of workpieces under different angles, resulting in inaccurate test results.

[0023] In view of the above problems, the present application discloses an environmental reliability test box, wherein the equipment uses a test box body 1 as the main detection container, the test box body 1 is a cavity shell with a rectangular structure, a test door is provided on one side of the test box body 1, the test door is hinged to the test box body 1 for opening and closing the test box body 1 so as to put in and take out the workpiece to be tested, a placement table 2 is provided in the center of the test box body 1 for placing the workpiece, a plurality of groups of spray controllers are arranged around the test box body 1, and the placement table 2 is wrapped in an encircling trend, so as to facilitate the simulation of rain erosion problems from different angles, and the plurality of groups of spray controllers are installed on a plurality of walls of the test box body 1 except the bottom surface of the test box body 1, and are adjusted accordingly according to the different sizes of the walls of the test box body 1;

[0024] Furthermore, according to the instructions attached Figure 1-3 It can be seen that the specific components of the spray controller include a rectangular shell 3, a water supply pipeline 4 installed on one side of the shell 3, a plurality of spray heads 5 arranged in a matrix installed on the other side of the shell 3, and an angle adjustment component connecting the plurality of spray heads 5;

[0025] In the specific implementation process, the water supply pipeline 4 draws water for simulation from the outside, and a water supply pump 9 is connected to the water supply pipeline 4. The simulated rainwater is pumped into the housing 3 through the water supply pump 9. A diversion tank 7 is arranged in the housing 3 and is connected to the water supply pipeline 4 and a plurality of sprinkler heads 5 respectively. The rainwater is diverted by the diversion effect of the diversion tank 7, so that it is evenly sprayed from the plurality of sprinkler heads 5. The angle adjustment component can synchronously adjust the angles of the plurality of sprinkler heads 5 on the same diversion tank 7 in an integrated manner, thereby changing the angle of the sprinkler head 5 to simulate the real incident angle of rainwater;

[0026] In order to better simulate the spraying environment of rainwater, a pulse control valve 6 is provided at the connection position between one side of the housing 3 and the water supply pipeline 4. By pulse switching of the pulse control valve 6, the water is pulsed out from one side of the sprinkler head 5 to simulate the falling rainwater.

[0027] Furthermore, one side of the diversion liner 7 is a partially conical structure, and the other side of the diversion liner 7 is a rectangular structure matching the size of the outer shell 3. The hollow inner cavity of the diversion liner 7 matches the shape of the two sides, and the gradual transition realizes a uniform diversion effect, so that the rainwater is sprayed from different sides of the sprinkler head 5;

[0028] In order to better disassemble and assemble the sprinkler controller, a number of outer panels 8 are provided on the outer shell 3, and a number of mounting grooves are provided on the outside of the test box 1. The number of mounting grooves and the number of outer panels 8 are connected by a number of bolts. By disassembling and assembling the bolts, the outer panels 8 and the mounting grooves can be locked and unlocked, thereby removing the outer shell 3 from the test box for easy maintenance and inspection.

[0029] As a preferred solution, further, a plurality of through holes are provided on the plurality of outer panels 8 for a plurality of bolts to pass through and connect with a plurality of mounting grooves.

[0030] As a preferred solution, further, a plurality of flow diversion guide seats 10 are provided on the flow diversion liner 7 and arranged at intervals on one side of the shower head 5 to improve the uniformity of the flow diversion and guidance.

[0031] As a preferred solution, further, a plurality of spherical grooves 11 arranged in a rectangular array are provided on the diversion liner 7, and a plurality of spherical nozzles 12 connected to the spherical grooves 11 are provided at the tail end of the sprinkler head 5. The spherical nozzles 12 are matched and connected with the spherical grooves, so that the spherical nozzles can rotate in the spherical grooves, and the openings on the spherical nozzles 12 can allow simulated rainwater to pass from the spherical grooves into the sprinkler head 5, thereby ensuring the sealing of the rainwater entry and the position of the spherical grooves 11 while achieving angle adjustment.

[0032] As a preferred solution, further, the angle adjustment assembly includes a matrix frame 13, a plurality of adjustment ports corresponding to the spray heads 5 are provided on the matrix frame 13, and a first linear screw module 14 is connected to one side of the matrix frame 13, and a second linear screw module 15 is connected to one side of the first linear screw module 14, and the movement directions of the first linear screw module 14 and the second linear screw module 15 are perpendicular;

[0033] In the specific implementation process, the adjustment ports arranged in a matrix on the matrix frame 13 correspond to the spray heads 5, and the spray heads 5 are assembled, so that the matrix frame 13 can control the angles of several spray heads 5 in an integrated manner. The first linear screw module 14 and the second linear screw module 15 constitute a two-way adjustment system in a plane. The movement of the first linear screw module 14 is adjusted by the second linear screw module 15 to change one direction of the matrix frame 13, and then the other movement direction of the matrix frame 13 is changed by the first linear screw module 14. Then, under the two-way adjustment of the matrix frame 13, the end opening direction of the spray head 5 is adjusted, and the corresponding angle adjustment matching of the spray head 5 is achieved through the activity of the spherical groove and the spherical nozzle 12.

[0034] From the above, it can be generally known that the environmental reliability test box, by arranging multiple groups of spray controllers on a rectangular structure box, simulates rain spraying on the workpiece in an omnidirectional manner. The spraying direction of multiple groups of spray heads 5 of the spray controller can be adjusted through the angle adjustment component. It has a simple structure and is easy to control. It can omnidirectionally simulate the spray angle of rain in real conditions, so that the workpiece can work in a more realistic rain spray environment, thereby improving the accuracy of the reliability test.
