[0032] Example

[0033] Reference Figures 1-4The present invention discloses an integrated rain detection device, including a rain chamber body 1, an external pipeline module 2, and a circulating water tank 3. The rain chamber body 1 includes a box steel structure 4 that serves as the skeleton of the rain chamber body 1. An internal spray pipe 5 and a lighting lamp are fixed to the box steel structure 4 by bolts or welding. The internal spray pipe 5 includes a top spray pipe 6 installed on the box steel structure 4 and side spray pipes 7 installed on both sides of the box steel structure 4. Spray nozzles 8 are installed on the top spray pipe 6 and the side spray pipes 7 respectively.

[0034] The internal spray pipes 5, through the multi-directional pipe arrangement on the top and sides and in coordination with the spray nozzles 8, simulate a rainfall environment, so that the water flow can fully and evenly cover key waterproof testing areas such as vehicle body seams, doors, windows, and sunroofs. The lighting provides illumination for the interior of the rain chamber 1, making it easy for staff to observe the spray status in real time.

[0035] The steel structure 4 of the box body has a reserved unified water supply interface 9 and power supply interface 10. All water supply interfaces 9 are centrally located in the same position, and all power supply interfaces 10 are centrally located in the same position. The external pipeline module 2 can quickly connect with the rain chamber body 1 through the preset water supply interface 9 and power supply interface 10.

[0036] In this embodiment, the external pipeline module 2 is a prefabricated integrated module, including an integrated carrier 11 and a water supply pipe assembly 12, a vacuum tank 13, a water pump 14, and a filter 15 mounted on the integrated carrier 11. This invention adopts a standardized integrated design for the external pipeline module 2, prefabricating and assembling this module in the manufacturing plant. Utilizing specialized equipment and personnel ensures welding quality and connection accuracy, solving the problem of unstable quality in traditional on-site construction and improving the overall reliability of the equipment. This makes it a standard product applicable to all rain shower equipment. During on-site installation, only the external pipeline module 2 needs to be connected to the rain shower chamber 1 to complete the installation of this set of equipment. There is no need for cumbersome pipe cutting, welding, and debugging work on-site, thereby greatly reducing on-site construction difficulties, shortening the on-site construction cycle, reducing construction costs, and improving the quality and stability of the equipment.

[0037] Specifically, the water supply pipe group 12 includes a first water supply pipe 16, a second water supply pipe 17, a third water supply pipe 18, a bypass pipe 19, and multiple connecting branch pipes 20.

[0038] One side of the first water supply pipe 16 is connected to the circulating water tank 3, and the other side is connected to the vacuum tank 13. The vacuum tank 13 is used to stabilize the flow and replenish pressure and prevent negative pressure, maintain the pressure stability of the water supply system, avoid water supply abnormalities caused by pressure fluctuations, and ensure the stable operation of the water supply system. The other side of the vacuum tank 13 is connected to the input end of the water pump 14, and the output end of the water pump 14 is connected to the second water supply pipe 17. The other side of the second water supply pipe 17 is connected to the top of the filter 15. The first water supply pipe 16 and the water pump 14 are located on both sides of the vacuum tank 13, and the first water supply pipe 16 is connected to the upper side of the vacuum tank 13, and the water pump 14 is connected to the lower side of the vacuum pipe. The filter 15 connected to the second water supply pipe 17 is equipped with a filter screen to intercept impurities and prevent the spray pipes and nozzles from being blocked, thus ensuring the stability of the spray water quality.

[0039] The bottom of the filter 15 is connected to the third water supply pipe 18, and the end of the third water supply pipe 18 is sealed by a flange. In this embodiment, multiple connecting branches 20 are respectively connected to the body of the third water supply pipe 18, and the other side is respectively connected to the top spray pipe 6 and the side spray pipe 7 through the water supply interface 9. In this embodiment, the water supply interface 9 is a flange.

[0040] Pressure sensors 21 and flow sensors 22 are respectively installed on multiple connecting pipes 20; pressure regulating valves and electromagnetic flow sensors 22 are installed on the top spray pipe 6 and the side spray pipe 7.

[0041] Furthermore, one end of the bypass pipe 19 is connected to the second water supply pipe 17, and the other end is connected to the filter 15 and located below the filter screen. A bypass valve is installed on the bypass pipe 19. Under normal circumstances, the bypass valve is in the closed state. When the filter 15 is clogged, the bypass valve opens, and water flows directly from the second water supply pipe 17 to the third water supply pipe 18 at the bottom of the filter 15 through the bypass pipe 19, bypassing the clogged filter screen to achieve emergency water supply and ensure the continuous operation of the sprinkler system. At this time, the staff can open the inspection cover of the filter 15 to clean or replace the filter screen without affecting the operation of the equipment. After maintenance is completed, the bypass valve is closed, and the equipment returns to normal filtration and water supply status.

[0042] In this embodiment, a control system is also provided. The control system is signal-coupled with the pressure sensor 21 and the flow sensor 22, and is connected to the water pump 14, the electrical control box, the pressure regulating valve and the electromagnetic flow sensor 22.

[0043] In this embodiment, the water pump 14 provides power for the spray water supply. The water pump 14 adopts frequency conversion control, and the water pump 14 is connected to the vacuum tank 13 through a flexible rubber joint.

[0044] Furthermore, an electrical cabinet 23 is also provided on the integrated carrier 11. The electrical cabinet 23 supplies power to the lighting, switches, high-speed doors and other equipment inside the shower room 1 through the power supply interface 10. Dedicated connectors for high-voltage and low-voltage electricity are provided on the integrated carrier 11 to enable quick connection with the power supply interface 10.

[0045] Based on the modular design concept, the external components of the rain chamber 1 are integrated into a modular assembly, with only water and electricity fixed interfaces connected to the chamber's sprinkler system. By reducing the length of the water supply pipe group 12 and the wiring length of the control system, the space for the entire external pipeline module 2 is compressed.

[0046] Traditional solutions involve external piping arranged according to site conditions in an unrestricted, open manner, resulting in longer piping. With the same configuration as this invention, the external piping length in the traditional solution is approximately 28.5m.

[0047] The external piping of this invention is integrated and optimized, with a total length of approximately 25.1m, saving 3.4m of pipe and reducing the piping length by 12%. See the table below for a detailed comparison.

[0048] Serial Number External piping composition Traditional solution Invention Solution 1 Circulating water tank 3 to vacuum tank 13 4.8m 4.8m 2 Vacuum tank 13 to water pump 14 1.1m 0.2m 3 Water pump 14 to filter 15, including bypass pipe 19 5.1m 5.1m 4 Filter 15 to multiple connecting pipes 20 4.3m 1.8m 5 Three connecting pipes 20 to the rain chamber body 1 4.4m*3 4.4m*3 total 28.5m 25.1m

[0049] The circulating water tank 3 provides water for the equipment. When the vehicle enters the shower chamber 1, the control system starts the water pump 14. The water pump 14 draws water from the vacuum tank 13 through a flexible rubber joint. At this time, a negative pressure is formed inside the vacuum tank 13. Water from the circulating water tank 3 is continuously supplied to the vacuum tank 13 through the first water supply pipe 16. The vacuum tank 13 simultaneously plays the role of stabilizing the flow and replenishing pressure, preventing negative pressure, and maintaining a stable water supply pressure. After being pressurized by the water pump 14, the water is delivered to the filter 15 through the second water supply pipe 17. After impurities are intercepted by the filter screen to ensure water quality, the water flows from the bottom of the filter 15 into the third water supply pipe 18, and then splits into multiple connecting branch pipes 20. Pressure sensors 21 and flow sensors are connected to the branch pipes 20. The device 22 collects pressure and flow data of each branch in real time and feeds it back to the control system. The control system, through parameters, simultaneously links the water pump 14 to adjust the output power of the frequency converter, the opening of the pressure regulating valve on the connecting branch pipe 20, and the electromagnetic flow sensor 22 to ensure the balance and stability of pressure and flow. The water flow finally enters the internal spray pipe 5 of the rain chamber 1 through the water supply interface 9 (flange connection), and is sprayed out through the multi-directionally arranged spray nozzles 8 to simulate the natural rainfall environment, comprehensively and evenly covering key waterproof testing parts such as body seams, doors, windows, and sunroofs. The lighting provides illumination for the interior of the rain chamber 1 so that staff can observe the spray status in real time. The electrical cabinet 23 is connected to the power supply interface 10.

[0050] In this embodiment, the power supply interface 10 uses a stainless steel cable tray for wiring and the connection of the power supply interface 10 is sealed with glue to supply power to the lighting, switches, high-speed doors and other equipment of the rain chamber 1. The whole process achieves rapid on-site docking and installation through modular integration, and ensures the accuracy of testing through closed-loop control. At the same time, the protective design of the enclosure is adapted to the outdoor environment to ensure stable operation of the equipment.

[0051] In one embodiment, the integrated carrier 11 is a box, with a door on the side for personnel and equipment to enter and exit and for equipment maintenance. The box is equipped with an air conditioner for internal temperature control and ventilation, and a floor drain for drainage. In this embodiment, the box can not only meet the integration and fixation of all components, but also ensure the waterproof and dustproof requirements of the open-air site.

[0052] In another embodiment, the integrated carrier 11 can be configured as a base plate, suitable for rain shower equipment built in a workshop.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
