Description

Technical Field

[0001] This utility model relates to the field of testing tools, specifically to a multi-angle high-pressure rain spray test device. Background Technology

[0002] Rain testing devices are primarily used to test the performance of equipment under different rain conditions, such as testing the waterproofing of exterior automotive components. However, traditional rain testing devices have significant limitations. First, the spray angle is limited, typically spraying water from only one or a few fixed directions, failing to comprehensively simulate the complex and varied rain scenarios in reality, resulting in inaccurate test results. Second, they lack flexibility. For example, the automatically adjustable high-pressure water spray testing device disclosed in Chinese Patent Publication No. CN212493544U presents cumbersome and costly adjustments to the spray position and angle for devices of different sizes, consuming considerable time and manpower, leading to low experimental efficiency. Therefore, developing a rain testing device capable of spraying high-pressure water from multiple angles, with flexible adjustments and high efficiency, is of considerable practical significance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a multi-angle high-pressure rain spray test device.

[0004] The technical solution adopted in this utility model is as follows: A multi-angle high-pressure rain spray test device includes a device body and a device under test disposed within a housing. The device body is used to spray high-pressure water jets towards the device under test at multiple angles to simulate a rain test, wherein: The enclosure has a guide rail and a shelf at its bottom. The guide rail is located on one side of the shelf, and the device body is movably mounted on the guide rail. The device to be tested is mounted on the shelf. The device body includes a slider, an arc-shaped bracket, and a water spray module. The slider is movably mounted on a guide rail, and the arc-shaped bracket is fixed to the slider by a triangular iron. The arc-shaped bracket is arranged as a quarter-circle arc extending towards the device under test. The water spray module is installed at equal intervals on the arc-shaped bracket, wherein the water spray module includes the following components: The nozzle is cylindrical in shape, with its front end pointing towards the device under test and spraying a fan-shaped high-pressure water stream. The mounting hole is located on the side of the nozzle and is connected to the high-pressure pipeline; The fastener is located behind the nozzle and is assembled with the arc-shaped bracket.

[0005] This technical solution utilizes an arc-shaped bracket to distribute the water spray modules at multiple angles, simulating rain scenarios from different directions to test the waterproof performance of equipment. The guide rail and slider work together to adjust the position of the device body, quickly adapting to devices of different sizes and improving experimental efficiency. Specifically, the enclosure constructs a closed experimental space; the guide rail and slider work together to allow the device body to move horizontally, facilitating adjustment of the initial water spray position; the arc-shaped bracket, with its quarter-circle arc segment, utilizes geometric properties to allow the water spray modules to cover the device at multiple angles, simulating rain from different directions; the columnar nozzle design facilitates the convergence and spraying of high-pressure water; mounting holes connect to high-pressure pipelines to ensure stable water input; and fixing components securely mount the nozzles to the arc-shaped bracket, ensuring precise spray direction. The entire system achieves multi-angle high-pressure rain simulation through a coordinated mechanical structure. It should be noted that the high-pressure pipeline is a flexible hose, therefore its movement with the guide rail will not interfere with the overall movement of the arc-shaped bracket.

[0006] In addition, the multi-angle high-pressure rain spray test device proposed in this utility model also has the following additional technical features: According to one embodiment of the present invention, at least one set of device bodies is provided inside the cover, and each set of device bodies intermittently sprays high-pressure water jets toward the device under test, with each set of device bodies serving as a backup for the others.

[0007] In this technical solution, multiple sets of device bodies serve as backups for each other. If one set fails, the others can continue operating, avoiding experimental interruptions and ensuring the successful completion of the experiment. Intermittent spraying reduces the continuous impact of high-pressure water flow on the equipment under test, and the alternating spraying of each device body extends its service life.

[0008] According to one embodiment of this utility model, a control valve is installed on the high-pressure pipeline to control the water pressure and flow rate. The control valve is used to control the sequential spraying of water from different nozzles and adjust the spraying time of each nozzle to quickly switch between different experimental modes. A pressure sensor and a flow sensor are installed on the high-pressure pipeline to detect the water pressure and flow rate, respectively.

[0009] This technical solution achieves flexible control over the spray sequence and timing of different nozzles by installing a control valve and equipping it with a controller on the high-pressure pipeline, thereby enabling more efficient switching between various experimental modes. The controller forms a closed-loop control system through the control valve, pressure sensor, and flow sensor.

[0010] According to one embodiment of the present invention, the arc-shaped bracket is provided with four water spray modules, and the mounting holes on the four water spray modules are respectively oriented at 0°, 30°, 60° and 90° for connection to external high-pressure pipelines.

[0011] In this technical solution, the four water spray modules are installed at four different angles: 0°, 30°, 60°, and 90°. Therefore, the mounting holes and high-pressure pipes on them are also fixed according to this angle. The 0°-90° angle setting is closer to the actual rain shower scenario.

[0012] According to one embodiment of the present invention, the bending direction of the arc-shaped bracket ensures that the device under test is always located below it.

[0013] In this technical solution, the device under test is always positioned below it. Utilizing the geometric characteristics of the arc shape, a relatively concentrated water jet area can be formed. This also prevents the arc-shaped support from colliding with the device under test during its movement along the slide rail, thus protecting the device's safety.

[0014] According to one embodiment of the present invention, a drive shaft is provided at the bottom of the shelf to drive the device under test at the top of the shelf to rotate.

[0015] In this technical solution, a drive shaft is installed at the bottom of the shelf. A motor drives the drive shaft to rotate, and the rotational power is transmitted to the top of the shelf through the connection between the drive shaft and the shelf, causing the device under test to rotate accordingly. A single rotation process can complete multi-angle detection of the device, eliminating the need for multiple adjustments to the device position or detection angle, thus saving time and labor costs.

[0016] Compared with the prior art, this utility model has the following advantages: The water spray module is distributed at multiple angles by an arc-shaped bracket to simulate rain scenarios from different directions and test the waterproof performance of the equipment; the guide rail and slider work together to adjust the position of the device body, quickly adapt to equipment of different sizes, and improve experimental efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 like Figures 1 to 3 As shown, this embodiment provides a multi-angle high-pressure rain spray test device, including a device body 3 and a device under test 5 disposed within a housing 1. The device body 3 is used to spray high-pressure water jets towards the device under test 5 at multiple angles to simulate a rain test, wherein: The cover 1 has a guide rail 2 and a shelf 4 at its bottom. The guide rail 2 is located on one side of the shelf 4, and the device body 3 is movably mounted on the guide rail 2. The device to be tested 5 is mounted on the shelf 4. The device body 3 includes a slider 31, an arc-shaped bracket 32, and a water spray module 33. The slider 31 is movably mounted on the guide rail 2. The arc-shaped bracket 32 ​​is fixed to the slider 31 by a triangular iron. The arc-shaped bracket 32 ​​is arranged in the form of a quarter-circle arc extending towards the device under test 5. The water spray modules 33 are evenly installed on the arc-shaped bracket 32. The water spray module 33 includes the following components: Nozzle 331 is arranged in a columnar shape, with its front end facing the device under test 5 and spraying a fan-shaped high-pressure water stream; Mounting hole 332 is located on the side of nozzle 331 and is connected to high pressure pipeline; The fastener 333 is located behind the nozzle 331 and is assembled with the arc-shaped bracket 32.

[0023] like Figures 1 to 3 As shown, this technical solution uses an arc-shaped bracket 32 ​​to distribute the water spray modules 33 at multiple angles, simulating rain scenarios from different directions to test the waterproof performance of the equipment. The guide rail 2 and slider 31 work together to adjust the position of the device body 3, quickly adapting to different sizes of the test equipment 5 and improving experimental efficiency. Specifically, the cover 1 constructs a closed experimental space, and the guide rail 2 and slider 31 work together to realize the horizontal movement of the device body 3, facilitating the adjustment of the water spray starting position. The arc-shaped bracket 32 ​​is a quarter-circle arc segment, utilizing geometric characteristics to allow the water spray modules 33 to cover the test equipment 5 from multiple angles, simulating rain from different directions. The columnar setting of the nozzle 331 facilitates the convergence and spraying of high-pressure water flow, and the mounting hole 332 connects to the high-pressure pipeline to ensure stable water flow input. The fixing component 333 securely mounts the nozzle 331 onto the arc-shaped bracket 32, ensuring accurate water spray direction. The entire system achieves multi-angle high-pressure rain simulation through the coordinated mechanical structure. It should be noted that the high-pressure pipeline is a flexible hose, so it moves with the guide rail 2 without interfering with the overall movement of the arc-shaped bracket 32.

[0024] In addition, the multi-angle high-pressure rain spray test device proposed in this utility model also has the following additional technical features: According to one embodiment of the present invention, at least one set of device bodies 3 is provided inside the cover 1. Each set of device bodies 3 intermittently sprays a fan-shaped high-pressure water stream toward the device under test 5, and each set of device bodies 3 serves as a backup for each other.

[0025] In this technical solution, multiple sets of device bodies 3 serve as backups for each other. If one set fails, the others can continue to operate, avoiding experimental interruption and ensuring the successful completion of the experiment. Intermittent spraying reduces the continuous impact of high-pressure water flow on the device under test 5, and the alternating spraying of each set of device bodies 3 extends its service life.

[0026] According to one embodiment of this utility model, a control valve is provided on the high-pressure pipeline to control the water pressure and flow rate. The control valve is used to control the sequential spraying of water from different nozzles 331 and adjust the spraying time of each nozzle 331 to quickly switch between different experimental modes. A pressure sensor and a flow sensor are provided on the high-pressure pipeline to detect the water pressure and flow rate, respectively.

[0027] This technical solution achieves flexible control over the spray sequence and timing of different nozzles 331 by installing a control valve and equipping it with a controller on the high-pressure pipeline, thereby enabling more efficient switching between various experimental modes. The controller forms a closed-loop control system through the control valve, pressure sensor, and flow sensor.

[0028] According to one embodiment of the present invention, the arc-shaped bracket 32 ​​is provided with four water spray modules 33, and the mounting holes 332 on the four water spray modules 33 are respectively oriented at 0°, 30°, 60° and 90° for connection to external high-pressure pipelines.

[0029] In this technical solution, since the four water spray modules 33 are installed at four different angles, namely 0°, 30°, 60° and 90°, the mounting holes 332 on them are also fixed to the high-pressure pipes according to this angle orientation. The 0°-90° angle setting is closer to the actual rain shower scenario.

[0030] According to one embodiment of the present invention, the bending direction of the arc-shaped bracket 32 ​​ensures that the device under test 5 is always located below it.

[0031] In this technical solution, the device under test 5 is always located below it. Utilizing the geometric characteristics of the arc shape, a relatively concentrated water jet area can be formed. This also prevents the arc-shaped support 32 from colliding with the device under test 5 during its movement along the slide rail, thus protecting the safety of the device under test 5.

[0032] According to one embodiment of the present invention, the bottom of the shelf 4 is provided with a drive shaft, which drives the device under test 5 at the top of the shelf 4 to rotate.

[0033] In this technical solution, a drive shaft is installed at the bottom of the shelf 4. A motor drives the drive shaft to rotate, and the rotational power is transmitted to the top of the shelf 4 through the connection between the drive shaft and the shelf 4, causing the device under test 5 to rotate accordingly. A single rotation process can complete multi-angle detection of the device, eliminating the need for multiple adjustments to the device position or detection angle, thus saving time and labor costs.

[0034] The usage process of the above embodiments is as follows: like Figures 1 to 3 As shown, before the experiment begins, the device under test 5 is placed on the shelf 4. According to the size of the device, the main body 3 is moved by the guide rail 2 and the slider 31 to adjust the starting position of the water spray. The motor is turned on, and the drive shaft drives the device under test 5 on the top of the shelf 4 to rotate. At the same time, the high-pressure water source supplies water to the nozzle 331 through the soft high-pressure pipeline and the mounting hole 332. The nozzle 331 is columnar and concentrates the high-pressure water flow to spray towards the device under test 5. The four water spray modules 33 installed at different angles on the arc-shaped bracket 32 ​​use the arc geometry to cover the device under test 5 from multiple angles, simulating rain from different directions. The controller controls the different nozzles 331 to spray water in sequence and adjust the spraying time through the control valve. The pressure sensor and flow sensor detect the water flow parameters in real time and feed them back to the controller to form a closed-loop control, which can quickly switch the experimental mode.

[0035] When needed, multiple sets of device bodies 3 spray intermittently, and when one set fails, the other sets continue to work.

[0036] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
