Description

Technical Field

[0001] This utility model relates to the field of materials testing, and in particular to a simulated rainfall test stand with waterproof outer casing. Background Technology

[0002] Rain simulation testing benches for outerwear waterproofing are key experimental devices used in the apparel industry to evaluate the waterproof performance of waterproof fabrics and garments. With the increasing functionality of outdoor sports and rain gear products, consumers are demanding higher waterproofing performance from clothing in complex rainy environments. These testing benches simulate natural rainfall conditions to quantitatively test the waterproofing capabilities of key areas such as garment seams, fabric coatings, and seam sealing, providing data support for product development, quality control, and standards certification.

[0003] Traditional simulated rainfall testing platforms cannot fully cover the water absorption of all surfaces of clothing, especially creating blind spots in areas prone to water accumulation such as cuffs, hems, and shoulders. Furthermore, static spray patterns cannot replicate the dynamic impact of oblique rainfall on clothing, leading to discrepancies between test results and real-world usage scenarios, making it difficult to comprehensively verify the waterproof reliability of clothing under complex weather conditions. Utility Model Content

An annular guide rail and an annular nozzle are fixedly arranged below the fixed frame. The annular nozzle is located in the inner region of the annular guide rail. A moving component is slidably connected to the outer side of the annular guide rail. A fan for generating airflow is fixedly connected to the moving component. The motor is used to drive the moving component to move along the annular guide rail, so as to drive the fan to rotate around the suspension position of the outer jacket.

[0017] Example: This example provides a simulated rainfall test bench for the waterproofness of the outer casing. See [link / reference]. Figure 1-4 Specifically, it includes a fixed frame 1, a base plate 11 installed at the bottom of the fixed frame 1, and a motor 16. A suspension frame 12 for supporting the jacket to be tested is installed at the center of the upper surface of the base plate 11. An annular guide rail 13 and an annular nozzle 14 are fixedly installed below the fixed frame 1. The annular nozzle 14 is located in the inner area of ​​the annular guide rail 13. A moving component 2 is slidably connected to the outer side of the annular guide rail 13. A fan 15 for generating airflow is fixedly connected to the moving component 2. The motor 16 is used to drive the moving component 2 to move along the annular guide rail 13 so as to drive the fan 15 to rotate around the suspension position of the jacket.

[0018] In this embodiment, the fixed frame 1 and the base plate 11 constitute the main frame of the equipment, providing structural support. The suspension frame 12 fixes the outer jacket under test, ensuring it is in the center of the test position, which is the same as the function of a clothes hanger in the prior art. The annular guide rail 13 provides an annular motion path for the moving component 2, guiding the fan 15 to rotate around the outer jacket. The area of ​​the annular guide rail 13 is the same as the area of ​​the base plate 11. The vertically downward spray angle of the annular nozzle 14 forms a uniform water curtain around the outer jacket, simulating a rainfall environment. Moreover, the annular nozzle 14 has a voltage stabilizer to achieve a uniform and stable drop of the water curtain. The moving component 2 and the fan 15 rotate, causing the fan 15 to blow the water curtain to form a dynamic oblique water flow, impacting the various surfaces of the outer jacket. The motor 16 drives the moving component 2 to move along the guide rail, controlling the rotation trajectory of the fan 15. The motor 16 drives the moving component 2 to move along the annular guide rail 13, causing the fan 15 to rotate around the outer jacket. The annular nozzle 14 sprays out a water curtain, and the airflow generated by the fan 15 blows the water curtain toward the outer casing, forming a multi-directional, dynamic, oblique rainfall simulation that covers all surfaces of the outer casing and eliminates the test blind spots of traditional equipment.

[0019] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the moving component 2 includes a support plate 21, a motor 16 is fixedly mounted on the upper surface of the support plate 21, a gear 22 is fixedly provided at the output end of the motor 16, a toothed ring 23 is fixedly provided on the outer wall of the annular guide rail 13, the toothed ring 23 meshes with the gear 22, a support member is provided below the support plate 21, the support member is in contact with both sides of the annular guide rail 13, a connector is provided on one side of the support plate 21, and the connector is connected to the fan 15.

[0020] In this embodiment, the support plate 21 carries the motor 16, gear 22, and fan 15, serving as the main structure of the moving component 2. The motor 16 and gear 22 are driven by a gear 22-gear ring 23, converting the rotational force of the motor 16 into a circular motion along the guide rail. The gear ring 23 is fixed to the outer wall of the circular guide rail 13 and meshes with the gear 22 to ensure transmission accuracy and motion stability.

[0021] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the support includes four rotating wheels 3 and two annular bars 31. The four rotating wheels 3 are connected to the support plate 21 through shafts. The two annular bars 31 are respectively installed on the inner and outer sides of the annular guide rail 13. The groove in the middle of the rotating wheel 3 is located on the annular bar 31.

[0022] In this embodiment, the rotating wheel 3 contacts the annular bar 31 through a groove, reducing moving friction and supporting the weight of the support plate 21. The annular bar 31 serves as a guide structure for the guide rail, preventing the moving component 2 from derailing and ensuring accurate motion trajectory. The rotating wheel 3 rolls along the annular bar 31, converting sliding friction into rolling friction, reducing energy consumption and wear. The inner and outer annular bars 31 together constrain the position of the rotating wheel 3, preventing the moving component 2 from shifting and ensuring that the fan 15 rotates stably along the set path.

[0023] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the connector includes a connecting frame 4 that is fixedly connected to the support plate 21. The lower end of the connecting frame 4 is provided with two rotating shafts 41. The ends of the rotating shafts 41 are fixedly connected to the side of the fan 15, and nuts 42 are provided at the threads of the rotating shafts 41.

[0024] In this embodiment, the connecting frame 4 connects the support plate 21 and the fan 15, transmitting motion force. The rotating shaft 41 allows the fan 15 to rotate around the rotating shaft 41 to adjust the angle, and the nut 42 fixes the adjusted position.

[0025] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a connecting pipe 5 is fixedly provided at the upper end of the annular nozzle 14. The connecting pipe 5 is connected to an external water supply device, and water is transported into the annular nozzle 14 by pressure, and a water curtain is sprayed vertically downward through the annular nozzle 14.

[0026] In the specific implementation process, such as Figure 1 As shown, a water tank 6 is provided on the upper edge of the base plate 11. The vertically downward water curtain from the annular nozzle 14 falls directly into the water tank 6, surrounding the outer sleeve on the suspension bracket 12. A water outlet pipe 61 is fixedly provided on the edge of the base plate 11 and connected to the water tank 6. The water tank 6 collects the water flowing down after testing, preventing water from overflowing. The water outlet pipe 61 discharges the water in the water tank 6 to an external recycling system, realizing the recycling of water resources.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
