Description

Technical Field

[0001] This utility model belongs to the field of rain test chambers, and specifically relates to a rain test detection device. Background Technology

[0002] Rain test chambers are specialized testing facilities used to detect and evaluate the rainproof sealing performance of automobiles. Water spray nozzles arranged within the chamber ensure that the exterior surface of the vehicle under test is evenly covered by artificial rain, eliminating dead zones. This testing equipment employs a circulating water treatment system, where the rainfall intensity varies with the pressure and flow rate of the pipeline system to meet specified requirements. However, current technologies often use single spray heads. Although multiple nozzles may be installed, if a nozzle becomes blocked or damaged, it can easily cause uneven spraying, affecting test results. Furthermore, the large number of nozzles presents difficulties in troubleshooting and maintenance, severely impacting usability and efficiency. Additionally, the limited variety of nozzles and the relatively simple simulated scenarios during use cause inconvenience. Utility Model Content

A toothed ring is fixedly wrapped around the outer tube. The toothed ring meshes with a rack. The power source is fixed on the assembly frame. The power source is used to drive the rack to rotate the toothed ring and the outer tube on the inner tube. Multiple nozzles are grouped together and uniformly fixed in a ring on the outer tube. Multiple groups of nozzles are uniformly fixed on the outer tube. A water passage hole is provided through the inner tube near the interior of the laboratory. The number of water passage holes is the same as the number of groups of nozzles. The water passage hole communicates with the nozzle. The width of the water passage hole is greater than the interface between the nozzle and the water passage hole.

[0005] Furthermore, the spraying device also includes a pipe end cap, which is used to seal the inner pipe away from the tee side.

[0006] Furthermore, the spraying device also includes ball bearings, which are embedded in the pipe end cap and the top of the outer pipe, and the ball bearings are used to limit the position of the top of the outer pipe.

[0015] (III) Beneficial Effects One of the above technical solutions has the following advantages or beneficial effects: The device uses a spray pipe with an inner and outer tube structure. The nozzles mounted on the outer tube are arranged in a ring with multiple nozzles in a group. Combined with the toothed ring and the sliding rack structure on the mounting frame, the spray pipe can be rotated by driving the rack to slide, thereby realizing the function of switching between nozzles.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0018] Example 1: This utility model provides a rain test device: its structure includes a laboratory 1, a spray device 2 and a water supply pipe 3. The spray device 2 is installed on the inner side end face and the top of the laboratory 1, and the water supply pipe 3 is used to supply water to the spray device 2. The spray device 2 includes an outer pipe 201, a nozzle 202, a pipe limiting ring 203, a toothed ring 204, a rack 205, an assembly frame 206, a power source 207, a rack limiting ring 208, a main water pipe 209, a tee 210, an inner pipe 211, and a water inlet 214. Multiple inner pipes 211 are connected to the main water pipe 209 via multiple tee 210s. The outer pipe 201 is slidably sleeved on the inner pipe 211. Both the main water pipe 209 and the outer pipe 201 are positioned and assembled on the assembly frame 206 via the pipe limiting ring 203. The assembly frame 206 is fixed to the inner side end face and top of the laboratory 1. A rack 205 is also assembled on the assembly frame 206 via the rack limiting ring 208. The rack 205 slides within the limiting ring 208. The toothed surface of rack 205 is assembled facing the outer tube 201. A toothed ring 204 is fixedly wrapped around the outer tube 201. The toothed ring 204 meshes with the rack 205. The power source 207 is fixed on the assembly frame 206. The power source 207 is used to drive the rack 205 to rotate the toothed ring 204 and the outer tube 201 on the inner tube 211. Multiple nozzles 202 are grouped together and uniformly fixed in a ring on the outer tube 201. Multiple groups of nozzles 202 are uniformly fixed on the outer tube 201. A water passage hole 214 is provided through the inner tube 211 near the inside of the laboratory 1. The number of water passage holes 214 is the same as the number of groups of nozzles 202. The water passage hole 214 communicates with the nozzles 202. The width of the water passage hole 214 is greater than the interface between the nozzles 202 and the water passage hole 214.

[0019] It also includes a drain outlet 4 and a filter plate 5. The filter plate 5 is laid on the bottom surface of the interior of the laboratory 1, and the drain outlet 4 is used to collect the water filtered by the filter plate 5 and discharge it.

[0020] The spray device 2 further includes a sealing ring 216, which surrounds the water passage hole 214 on the side of the inner tube 211 adjacent to the outer tube 201. The sealing ring 216 is used to seal the water passage hole 214 when it is connected to the nozzle 202.

[0021] The sealing ring 216 is made of rubber.

[0022] In use, the vehicle is driven into laboratory 1, and water is supplied through the main water pipe 209 via the water supply pipe 3. Water enters the inner pipe 211 from the main water pipe 209, and then sprays out from the inner pipe 211 through the water passage 214 and the nozzle 202. During use, if a nozzle becomes clogged, or if there are different simulation requirements, the rack 205 can be driven by the power source 207 to rotate the gear ring 204, thereby rotating the outer pipe 201. This allows for the switching of the nozzles 202 assembled in a ring on the outer pipe 201. If a single type of nozzle 202 is assembled, it serves as a backup nozzle. If different types of nozzles 202 are assembled, different simulation scenarios can be switched, avoiding the inconvenience of repairing a single nozzle. This is convenient, quick, and allows for continuous use without dead angles, ensuring the effectiveness and efficiency of the application.

[0023] Example 2: Compared to Embodiment 1, the spray device 2 described in this embodiment further includes a pipe cap 213, which is used to cover the inner pipe 211 on the side away from the tee 210.

[0024] The spray device 2 also includes a ball bearing 212, which is embedded in the top of the pipe end cap 213 and the outer pipe 201. The ball bearing 212 is used to limit the position of the top of the outer pipe 201.

[0025] When in use, the ball bearing 212 can prevent the outer tube 201 from rotating and loosening the tube end cap 213. At the same time, after removing the tube end cap 213, the outer tube 201 can be easily replaced and cleaned, which is convenient for maintenance and use. The rest of the structure and effect remain unchanged.

[0026] Example 3: Compared to the previous embodiments, in this embodiment, each group of multiple nozzles 202 consists of different nozzles.

[0027] The spray device 2 also includes a threaded connector 215, which is used to lock the inner tube 211 to the tee 210.

[0028] Example 4: Compared to the previous embodiments, the power source 207 in this embodiment is a combination of a motor and gears. The motor is fixed on the laboratory 1 or the assembly frame 206, and the motor drives the rack 205 to move through the gears.

[0029] Example 5: Compared to the previous embodiments, the power source 207 in this embodiment is a combination of an electrically controlled telescopic rod 20701 and a connecting plate 20702. The electrically controlled telescopic rod 20701 is fixed on the laboratory 1 or the assembly rack 206, and the connecting plate 20702 is fixed on the rack 205. The telescopic rod body of the electrically controlled telescopic rod 20701 is fixedly connected to the connecting plate 20702.

[0030] The electrically controlled telescopic rod 20701 is a hydraulic pump, a pneumatic pump, or an electric push rod.

[0031] Example 6: Compared to the previous embodiments, the three-way valve 210 in this embodiment adopts an electrically controlled three-way valve, which makes it convenient for users to adjust whether the spray pipe is used and the water pressure of the spray according to their needs, while the rest of the structure and effect remain unchanged.
