[0004] Therefore, it is necessary to design a rain test chamber resistant to strong winds to solve the above problems. Utility Model Content

The two ends of the high-pressure pump are respectively connected to a water inlet pipe and a spray pipe, and multiple high-pressure nozzles are connected to the bottom of the multiple spray pipes.

[0007] Preferably, a second air guide plate is fixedly connected to the top of the air inlet, and one end of the second air guide plate is attached to one side of the box body, and the width of the second air guide plate is equal to the width of the fixed box.

[0008] Preferably, the outer surface of the housing away from the air inlet has a placement opening, and the outer surface of the placement opening is connected to a mounting cover plate by bolts.

[0009] Preferably, a mounting plate is fixed to the bottom of the housing, and mounting holes are provided at the four corners of the mounting plate, and the air supply pipe is L-shaped.

[0018] 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.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3 This utility model provides a strong wind-resistant rain test chamber, including a chamber body 1. An air inlet 21 is connected to one side of the chamber body 1. Two symmetrical first rotating shafts 11 are rotatably connected to one end of the air inlet 21, and a second bevel gear 10 is fixedly connected to the top of each first rotating shaft 11. A fixed box 8 is fixedly connected to the top of the air inlet 21, and a servo motor 7 is fixedly connected to one side of the fixed box 8. A second rotating shaft 20 is fixedly connected to the output shaft of the servo motor 7, and two symmetrical first bevel gears 9 are fixedly connected to the outer surface of the second rotating shaft 20. The two first bevel gears 9 mesh with the two second bevel gears 10 respectively, and each of the two first rotating shafts 11 is fixedly fitted with an adjustment plate 17, with one end of the two adjustment plates 17 touching each other. An air supply pipe 6 is fixedly inserted into the bottom of the air inlet 21, and a fan 18 is fixedly connected to the bottom end of the air supply pipe 6. Multiple guide ports 4 are connected to both sides of the air inlet 21, and a first air guide plate 3 is fixedly connected between each of the two guide ports 4 and both sides of the air inlet 21. Multiple exhaust holes 16 are opened on one side of the housing 1. A high-pressure pump 15 is fixedly connected to one side of the housing 1. The two ends of the high-pressure pump 15 are respectively connected to a water inlet pipe 14 and a spray pipe 12. Multiple high-pressure nozzles 13 are connected to the bottom of each spray pipe 12. During testing, the test item is placed inside the housing 1, and the high-pressure pump 15 is activated to spray water at high pressure onto the object's surface, thus conducting a rain test. The operation of the fan 18 and the introduction of external wind simulate extreme weather conditions such as heavy rain and strong winds. Air is exhausted through multiple exhaust vents 16. Simultaneously, the air... By turning on the servo motor 7, the meshing of two first bevel gears 9 and two second bevel gears 10 allows the size of the opening between the two control plates 17 to be adjusted, thereby regulating the amount of airflow entering the housing 1. In cases where the external wind force is strong and the housing 1 may not be able to conduct stable testing, the setting of multiple air guide ports 4 can disperse the wind force and avoid excessive impact from the external wind force. Furthermore, the setting of two first air guide plates 3 and one second air guide plate 5 reduces the impact of the wind force on the housing 1, thereby improving the strong wind resistance efficiency of the housing 1.

The width of the second air guide plate 5 is equal to the width of the fixed housing 8.

[0022] To facilitate the placement of test samples inside the housing 1, a placement opening is provided on the outer surface of the housing 1 on the side away from the air inlet 21, and a mounting cover plate 19 is connected to the outer surface of the placement opening by bolts.

[0023] To facilitate the fixation of the device and increase its stability during testing, a mounting plate 2 is fixedly connected to the bottom of the housing 1, and mounting holes are provided at the four corners of the mounting plate 2. The air supply pipe 6 is L-shaped.

[0024] In order to disperse and guide strong external winds and reduce the impact of external wind force on the housing 1, the guide port 4 is arc-shaped, and the guide port 4 is located on both sides of one end of the air supply pipe 6. The outer surface of the housing 1 is provided with an arc shape.

[0025] Furthermore, in order to adjust the amount of airflow into the housing 1, both control plates 17 are rotatably mounted inside the air inlet 21, and the top and bottom of the two control plates 17 are respectively attached to the top and bottom of the inner cavity of the air inlet 21.
