Description

Technical Field

[0001] This utility model mainly relates to the field of environmental simulation and testing technology, specifically to an outdoor equipment rain test device. Background Technology

[0002] In the research and development and production of outdoor equipment, rain testing is a key step in testing the waterproof performance and environmental adaptability of the equipment.

[0003] Traditional outdoor equipment rain test devices mostly adopt a fixed structure. The spray rack cannot be folded and stored, occupying a large amount of test space. Moreover, it is easy to waste space resources when the equipment is not in use. Fixed spray racks are difficult to adjust their position flexibly according to the test equipment of different sizes, resulting in uneven rain coverage and poor test results. Some devices do not fully consider the insufficient support caused by flexible connecting parts in their structural design, resulting in poor stability of the spray rack during the test, which affects the accuracy and reliability of the test data.

[0004] Existing rain test devices cannot simultaneously meet the multiple requirements of space utilization, test flexibility and structural stability. For example, although some devices have folding functions, the sealing performance decreases after folding, leading to water leakage. Or, although they can be moved and adjusted, they lack an effective support structure, and there is a risk of shaking during operation.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0031] See attached document Figure 1-4 An outdoor equipment rain test device includes a ground track 1 and a spray frame. The lower end of the spray frame is equipped with pulleys 2 that match the ground track 1. The spray frame includes two side pipe frames 3 and an upper pipe frame 4. One end of the side pipe frame 3 is equipped with a water inlet pipe 14, and a pressure regulating valve 17 is provided on the water inlet pipe 14. The two upper pipe frames 4 are located above the side pipe frames 3. Corrugated pipes 5 are provided on the two upper pipe frames 4. A transverse connecting pipe 15 is connected between the two corrugated pipes 4. The upper pipe frame 4 and the side pipe frame 3 are connected by a corrugated pipe 6. Supporting rods 7 are also provided at both ends of the side pipe frame 3. Several spray heads 8 are distributed on the inner side of the side pipe frame 3 and the lower end of the upper pipe frame 4. A vertical connecting pipe 16 is connected to the side pipe frame 3.

[0032] The core structure of this outdoor rain test device includes a ground track 1 and a spray frame. The two are dynamically coordinated through mechanical connection. The lower end of the spray frame is equipped with a pulley 2 that is precisely matched with the ground track 1. The pulley 2 is made of polyurethane and is fixedly connected to the bottom support of the spray frame through a bearing seat. It can slide freely along the T-shaped groove of the track 1. The ground track 1 has a two-section structure and is locked in the middle with screws. During use, it can be fixed to the ground with bolts.

[0033] The main body of the spray frame consists of two side pipe frames 3 and an upper pipe frame 4. The side pipe frames 3 are vertical, and their lower ends are fixed to the support beam of the pulley 2 by bolts. Their upper ends are connected to the upper pipe frame 4 by the bent pipe 10. The two upper pipe frames 4 are set parallel to the top of the side pipe frames 3 and are sealed to the bent pipe 10 by corrugated pipes to form a top horizontal support structure. The spray frame is erected on the ground track 1 by the pulley 2. During the test, the position can be adjusted by sliding along the track so that the spray frame covers the equipment under test in the center, or it can be moved back and forth according to the test requirements to realize the rain simulation at different positions.

[0034] Corrugated pipe 5 and corrugated pipe 6 serve as flexible connecting components. The sleeve joints 9 at both ends are made of stainless steel and are fixed to the pipe ports of the upper pipe rack 4 and the side pipe rack 3 by threaded connection. O-rings are set on the inner side of the sleeve joints to ensure that the water flow is sealed and leak-proof. Corrugated pipe 5 connects the two upper pipe racks 4 laterally, allowing them to fold relative to each other. Corrugated pipe 6 is used to connect the upper pipe rack 4 and the side pipe rack 3, allowing the upper pipe rack 4 and the side pipe rack 3 to fold relative to each other. When the device is not in use, the two side pipe racks 3 can be folded inward by the flexible deformation of corrugated pipe 5 and corrugated pipe 6, and the upper pipe rack 4 is pressed down at the same time, so that the spray rack shrinks into a flat shape, which greatly reduces the storage space and avoids occupying the test site.

[0035] A bend 10 is installed at the upper end of the side pipe support 3. The bend 10 adopts a 90° arc structure. One end of the bend 10 is fixed to the top pipe of the side pipe support 3 by welding, and the other end is connected to the sleeve joint 9 by thread. The sealing ring inside the sleeve joint 9 fits tightly with the port of the bend 10 to prevent water leakage. The bend 10 makes the upper pipe support 4 and the side pipe support 3 form a vertical connection. At the same time, it provides an installation interface for the second corrugated pipe 6, ensuring that the second corrugated pipe 6 rotates with the upper pipe support 4 when folded. The second corrugated pipe 6 adapts to the angle change through elastic deformation, without affecting the pipeline connectivity.

[0036] Multiple branch pipes 11 are evenly distributed on the pipes of the side pipe rack 3 and the upper pipe rack 4. The branch pipes 11 are connected to the main pipe. The device uses the side pipe rack 3 and the upper pipe rack 4 as the main pipes, forming a flow pipeline with the branch pipes 11. Spray heads 8 are vertically installed at the ends of the branch pipe racks. The spray heads 8 are fan-shaped nozzles with adjustable spray angles. The spray heads 8 on the inside of the side pipe rack 3 spray water towards the side of the equipment, and the spray heads 8 at the bottom of the upper pipe rack 4 spray water towards the top of the equipment, forming a three-dimensional rain coverage. The diameter of the branch pipes 11 is designed according to the flow rate of the main pipe. The water inlet pipe 14 is connected to the water source. The pressure is increased or decreased by the pressure regulating valve 17. The pressure regulating valve 17 is equipped with a pressure gauge, which can monitor the water pressure in real time to ensure that the water pressure of each spray head 8 is uniform and meets the requirements of the water flow intensity in the rain test standard.

[0037] Positioning pins 12 are welded to the outer sides of both the side tube frame 3 and the upper tube frame 4. The positioning pins 12 are cylindrical and are vertically fixed to the preset positions on the outer sides of the tube frames, corresponding to the installation points of the support connecting rods 7. The support connecting rods 7 are metal rods with positioning grooves 13 at both ends. The width of the positioning grooves 13 matches the diameter of the positioning pins 12. By inserting the positioning pins 12 into the positioning grooves 13, the support connecting rods 7, the side tube frame 3, and the upper tube frame 4 form a triangular support structure. When the spray frame is unfolded, the positioning grooves 13 at both ends of the support connecting rods 7 are fitted onto the positioning pins 12 and fixed by pins or retaining rings to prevent the support connecting rods from falling off and to ensure that the spray frame remains stable during the test. When it is necessary to fold the spray frame, simply remove the fixing pins and remove the support connecting rods 7 from the positioning pins 12 to achieve flexible folding of the spray frame.

[0038] The horizontal connecting pipe 15 and the vertical connecting pipe 16 are respectively connected to the upper pipe rack 4 and the side pipe rack 3 by locking nuts to form a detachable structure. They can be added or removed according to the size of the test equipment. The horizontal connecting pipe 15 can realize the adjustment of the width of the device, and the vertical connecting pipe 16 can realize the adjustment of the height of the device.

[0039] In summary, this technical solution utilizes the flexible connection between corrugated pipe one and corrugated pipe two to allow the spray frame to be folded into a flat shape. The sealing design of the sleeve joint ensures that the pipeline does not leak when folded, thus solving the problem of space occupation. The horizontal movement of the spray frame is achieved through the cooperation of pulleys and ground tracks, and the position can be adjusted according to the equipment size, making the rain coverage more precise. The support link 7 is movably connected to the positioning slot through the positioning pin, forming a triangular support when the spray frame is unfolded, compensating for the insufficient support of the flexible corrugated pipe connection and ensuring the structural stability of the spray frame during the test.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
