[0030] Furthermore, in order to prevent water from flowing out from the gap between the protective cover 7 and the bottom wall of the annular groove 3001, a sealing strip is provided on the lower side of the protective cover 7.

[0031] The working steps of this embodiment are: The following description is based on the perspective of the figure, where the side where the base frame 1 is located is the front side; The following rotations are from front to back, from top to bottom, and from right to left. When in use, first place the performance testing device for rain gear at a required position; The operator connects an external power supply to all components that need to be powered by electricity, connects a water pipe to the water inlet end of the sprinkler head 6, and connects an external hot air device to the air inlet pipe 402 and the air connection pipe 30301. Before the test, the operator first opens the umbrella 9 to be tested. Figure 7As shown, the opened umbrella 9 is placed in the annular groove 3001 of the receiving plate 3, and the umbrella bead of the umbrella 9 contacts the bottom wall of the annular groove 3001, and then the telescopic parts of the two first electric push rods 101 are controlled to contract, driving the connecting rods 102, the semicircular plates 103, the clamping blocks 104 and the round tube 105 on both sides to move toward the opposite sides, so that the two semicircular plates 103 and the two clamping blocks 104 are combined, and the two clamping blocks 104 clamp the skeleton of the umbrella 9, and the two missing gears 109 are combined to form a complete gear ring, and then the electric slider 202 is controlled to move downward on the electric slide rail 201, and the two electric sliders 202 drive the mounting bracket 5, the sprinkler head 6 and the protective cover 7 to move downward together, until the lower surface of the protective cover 7 contacts the inner bottom wall of the annular groove 3001 of the receiving plate 3, and then the two electric sliders 202 are controlled to stop moving; Then the operator controls the sprinkler head 6 to spray water to test the umbrella 9 for water leakage. The water falling on the umbrella 9 will flow into the annular groove 3001 of the receiving plate 3, and then flow from the plurality of through holes 3002 to the U-shaped grooves 10301 of the two semicircular plates 103, and then flow from the circular tubes 105 of the two semicircular plates 103 to the water storage box 8 below. After the umbrella 9 is continuously sprayed with water for a period of time, the sprinkler head 6 is controlled to stop spraying water; then the two detection components are controlled to operate synchronously. Taking the left detection component as an example, the telescopic parts of the two second electric push rods 301 are controlled to contract, driving the arc plate 302, the arc tube 303, the vertical tube 304, the fixing ring 305, the spring 306 and the water leakage sensor 307 to move upward together, so that the four vertical tubes 304 pass through the semicircular plate 103, and make the four water leakage sensors 307 contact with the rain cloth on the umbrella 9, and then the motor 107 is controlled. The output shaft drives the spur gear 108 to rotate clockwise, and the spur gear 108 drives the clamping block 104, the missing gear 109 and the umbrella 9 to rotate together, and the inner side of the rain cloth of the umbrella 9 is detected by the water leakage sensor 307; when the water leakage sensor 307 rotates one circle along the rain cloth of the umbrella 9 without triggering the alarm, the telescopic parts of all the second electric push rods 301 are controlled to be pushed out, driving the connected parts and the water leakage sensor 307 to move downward together for reset, so that the water leakage sensor 307 no longer contacts the umbrella 9. When water leakage occurs on the umbrella 9, the leaked water will flow downward along the rain cloth of the umbrella 9. When any water leakage sensor 307 contacts water, the conductivity of water will cause the circuit between the electrodes on the water leakage sensor 307 to be turned on, thereby triggering an alarm, prompting the operator that the waterproof performance of the umbrella 9 is unqualified, so as to realize the waterproof performance detection of the umbrella 9.

[0032] During use, especially in windy weather, the umbrella 9 may be subjected to external forces from different directions, including stretching, compression and torsion, etc. At the same time, people tend to twist the umbrella 9 from time to time when using it. If the structure of the umbrella 9 is not strong enough, it is easy to cause problems such as frame deformation and seam cracking, which will affect the reliability and durability of the umbrella 9. Therefore, after the water leakage detection of the umbrella 9 is completed, the operator controls the output shaft rotation speed of the motor 107 to gradually increase, so that the torque applied to the umbrella 9 is within the range that the hand of an ordinary adult male can apply torque, and gradually increases from small to large. Add, simulate the different degrees of external force that the umbrella 9 may encounter in actual use, test the quality and stability of the umbrella 9 structure, stop after rotating 50-60 circles, use the micro camera 10302 or directly remove the umbrella 9 to detect the internal skeleton of the umbrella 9 to confirm whether the internal skeleton of the umbrella 9 is deformed, bent or broken, so as to test the quality and stability of the umbrella 9 structure and ensure the reliability and durability of the umbrella 9. The motor 107 used for waterproof detection is also used to detect the quality and stability of the umbrella 9 structure, thereby reducing power costs and reducing additional device costs.

[0033] While the output shaft of the motor 107 is rotating continuously with the umbrella 9 to detect water leakage, quality and stability, the water drops attached to the umbrella 9 are thrown away. After the umbrella 9 rotates for a period of time and the rain attached to the umbrella 9 is thrown away, the output shaft of the motor 107 stops rotating. At this time, the hot air device is controlled to deliver hot air to the two jet pipes 401 and the two air inlet pipes 402, and the umbrella 9 is dried by continuously spraying hot air through the several jet holes of the two jet pipes 401. When the operator observes the drying of the umbrella 9 through the transparent protective cover 7, the hot air drying time is recorded to evaluate the drying rate of the umbrella 9. After the detection is completed, the two jet pipes 401 are controlled to stop delivering gas, and then the two electric sliders 202 are controlled to drive the connected components to reset upwards.

[0034] It should be noted that, when the umbrella 9 stops rotating, the fan is controlled to start, and gas is continuously ejected through the several jet holes of the jet pipe 401, and then the output power of the fan is controlled to gradually increase, so that the airflow ejected from the several jet holes of the jet pipe 401 gradually becomes larger, simulating different degrees of strong wind that the umbrella 9 may encounter in actual use, and testing the wind resistance of the umbrella 9. When the umbrella 9 is obviously deformed, the maximum wind force ejected from the jet pipe 401 at this time is recorded to evaluate the wind resistance of the umbrella 9.

[0035] When the umbrella 9 is used in a strong wind, the umbrella 9 may turn over. After the umbrella 9 turns over, the components of the umbrella 9 are easily damaged, affecting the normal use of the umbrella 9. Therefore, the telescopic parts of all the second electric push rods 301 can be controlled to contract, drive the connected components to move, and move the eight vertical pipes 304 to the inside of the umbrella 9. Then, the external fan can be controlled to start, and the output power can be controlled to be adjusted to the maximum, so that the gas is transported to the air receiving pipe 30301, the arc tube 303 and the vertical pipe 304, and then discharged from the exhaust holes 30401 of the eight vertical pipes 304. The large air blown out through the several exhaust holes 30401 of each vertical pipe 304 The airflow is measured and acts on the inner side of the umbrella 9 to turn the umbrella 9 over. Then, the two electric sliders 202 are controlled to drive the connected parts to move downward, and the two air jets 401 are moved to the upper side of the umbrella 9. Then, the external fan is controlled to be turned on to allow the air jet holes of the two air jets 401 to continuously spray airflow to turn the turned umbrella 9 back to its original state. This operation is repeated for multiple times to ensure the rationality of the test. After the umbrella cloth of the umbrella 9 is turned upward, the external fan is controlled to be turned off. The operator observes whether the frame and the umbrella cover of the umbrella 9 are damaged after the umbrella 9 has been turned over many times to test the overall quality of the umbrella 9.

[0036] It should be noted that, in the process of the sprinkler head 6 spraying water on the umbrella 9, some water droplets will splash around under the action of the umbrella 9 and fall onto other components of the device. The splashing water droplets can be intercepted by the protective cover 7 and confined within the protective cover 7. At the same time, when the umbrella 9 rotates, the splashing water droplets can also be intercepted by the protective cover 7 to prevent the water droplets on the umbrella 9 from being thrown away and causing damage to other electrical components of the device.

[0037] The present invention integrates waterproof detection, structural quality and stability detection, drying rate detection, wind resistance detection and umbrella cover strength detection after flipping, and has high practicality and diversity.

[0039] It also includes a support component, which is connected to the receiving plate 3; the support component includes a joint 505, a U-shaped tube 506 and an airbag 507; an L-shaped channel 3003 is opened on the receiving plate 3; the joint 505 is installed on the upper surface of the receiving plate 3, and the joint 505 is connected to the L-shaped channel 3003; the U-shaped tube 506 is installed on the inner side of the receiving plate 3, and the U-shaped tube 506 is connected to the L-shaped channel 3003; the airbag 507 is embedded in the inner side of the annular groove 3001 of the receiving plate 3, and the U-shaped tube 506 is connected to the airbag 507.

[0040] The working principle of this embodiment is: The operator first adds a large amount of water into the water storage box 8, connects an external air pump to the joint 505, and before testing the umbrella 9, controls the pump 501 to start, and the water in the water storage box 8 is transported to the sprinkler head 6 through the curved pipe 504, the pump 501, the telescopic pipe 502 and the connecting pipe 503, and the tested water will flow back into the water storage box 8 again. Under the action of the pump 501, the water in the water storage box 8 can be recycled, saving a lot of water resources.

[0041] When the umbrella 9 is placed on the receiving plate 3 and clamped, the external pump is controlled to start, and gas is transported into the airbag 507 through the joint 505, the L-shaped channel 3003 and the U-shaped tube 506, so that the airbag 507 expands, and the umbrella 9 is received by the expanded airbag 507 to prevent the water sprayed by the sprinkler head 6 from impacting and deforming the frame of the umbrella 9. After the sprinkler head 6 stops spraying water, the external pump is controlled to extract the gas in the airbag 507, so that the expanded airbag 507 shrinks and no longer receives the umbrella 9.
