Description

Technical Field

[0001] The invention relates to a matrix type dynamic rain test device, and relates to the technical field of detection equipment. Background Art

[0002] After the production of some products is completed, a rain test is required to test the product's waterproof performance, sealing performance, etc.

[0003] Rain test usually uses a sprinkler system to conduct multi-directional spray test on the product, and also simulates the rain effect in different environments through flow and pressure control, so as to test the real data of the product under different spray conditions. However, the nozzle setting of the existing sprinkler system is not reasonable. Only multiple single nozzles are set on each single pipeline, and its coverage is limited. It is inevitable that the product cannot be fully covered during spraying, which easily causes test differences in regional spray effects and affects the test structure. At the same time, the response speed of flow and water pressure control is slow, and the effect is poor when dynamic adjustment is performed. Since the monitoring mechanism only detects the flow and pressure on the water pump, the spraying conditions of each pipeline are not fully monitored. When an abnormality occurs in a pipeline, it cannot be discovered and checked in time, affecting the test effect.

DETAILED DESCRIPTION

[0025] See Figure 1-Figure 7As shown, the technical solution adopted in this specific embodiment is: it includes a spray box body 1, a pipe bracket 2, the pipe bracket 2 is arranged on the outside of the spray box body 1 and extends to the top, an axial water storage pipe 15 is arranged on the top of the pipe bracket 2, and a plurality of spray main pipes 14 are arranged in parallel below the water storage pipe 15 through a connecting pipe, and a first flow pressure integrated transmitter 27 is provided on the connecting pipe, and the spray main pipe 14 is an inverted U-shaped structure, and the vertical sections on both sides of the spray main pipe 14 extend to the bottom along the side wall of the spray box body 1, and the spray main pipe 14 is provided with a Y-shaped spray head 16 toward the center side of the spray box body 1, and water supply pipes 8 are provided on the bottom of both sides of the spray main pipe 14, a water tank 6 is provided on the outside of the spray box body 1, and a diversion pipe 9 is provided at the bottom of the water tank 6 to connect with the water supply pipe 8. A control system 26 is also provided on the outside of the spray box body 1. In this embodiment, the equipment is installed as a whole in the installation slot of the test site. The inverted U-shaped design of the spray main pipe enables the spray main pipe to The spray heads are arranged in a Y-shape on the inside of the spray main pipe, facing the center of the spray box. The spray heads are symmetrically arranged on the spray main pipe, with two heads in each group. The spacing between the spray main pipes matches the spray surface range of the spray heads. That is, the spacing between the two groups of spray main pipes is slightly smaller than the sum of the spray surface radii of two adjacent spray pipes. Therefore, the spray surfaces of two adjacent spray heads on the two groups of spray main pipes intersect at the edges. Since the spray heads in the same group are arranged in a Y-shape, their spray surfaces also intersect at the edges. The spray heads are arranged at equal distances along the entire spray main pipe, forming a matrix arrangement. Therefore, it can effectively cover the entire surface of the test equipment, such as the vehicle, except for the bottom surface. Traditional spray systems, most of which are equipped with a main nozzle and a small number of auxiliary nozzles on a single spray pipe, have a smaller coverage area. The equipment surface often suffers from regional uneven spraying due to insufficient coverage or excessive intersection, affecting the spray test effect.

[0026] This embodiment also provides a multi-mode spray system, and multi-mode spray modes are preset in the control system, which can simulate light rain, moderate rain, heavy rain and rainstorm modes, and are controlled according to the flow rate per minute. The first flow and pressure integrated transmitter integrates flow and pressure sensors, and can monitor the spraying situation in real time. The detection data will also be returned to the control system in real time to ensure the accuracy of the simulation effect. At the same time, it can also be determined whether a pipeline is abnormal through monitoring data. Maintenance personnel can inspect the corresponding pipeline according to system feedback, eliminate faults in time, and ensure the smooth progress of the test.

[0027] To be more specific, a filter 10 is provided in the middle of one side of the bottom of the spray box 1, and a second variable frequency water pump 11 is provided on the filter 10, which is connected to the water storage pipe 15 through a circulation pipe 13, and a pressure gauge 12 is provided on the circulation pipe 13 near the second variable frequency water pump 11. In this embodiment, the filter is installed in the installation groove of the test site and is not exposed to the surface of the site. It filters and recycles the spray water. A pressure gauge is provided on it to monitor the output pressure to ensure that the output is normal. The pressure gauge will transmit the data back to the control system, which can be observed on site or monitored by the control system, so that effective monitoring can be achieved during the use of circulating water to prevent the filter from failing and impurities from flowing into the circulation pipe and causing blockage and poor circulation.

[0028] To be more specific, a first variable frequency water pump 7 is provided at the bottom of the water tank 6 and is connected to a diversion pipe 9. Specifically, a water tank bracket 5 for fixing the water tank is provided at the bottom of the water tank, and the water tank bracket is also used to protect the first variable frequency water pump. The water supply pipe 8 is connected to the diversion pipe 9 through a control valve 901, and a second flow pressure integrated transmitter 902 is provided at the connection section between the control valve 901 and the diversion pipe 9. The water supply of the overall spraying system is extracted from the water tank by the first variable frequency water pump, and the water is transported to the water supply pipe through the diversion pipe and then to the spray main pipe for spraying. The control valve needs to be closed when not in use to prevent water supply due to misoperation when no test is performed. The second flow pressure integrated transmitter can monitor the water output in real time to ensure normal output and can promptly feedback to the control system for timely processing in case of abnormality.

[0029] To be more specific, the water tank 6 is provided with a multi-stage filtering mechanism (not shown) and a stirring mechanism (not shown), a water inlet pipe 601 is provided on the top of the water tank 6, a one-way injection valve 602 is provided on the side of the water tank 6, and a pH detection device (not shown) for detecting water quality is also provided inside the water tank 6. A drain valve (not shown) for discharging waste water is also provided at the bottom of the water tank 6. In this embodiment, the water tank is a multi-stage filtering and water quality regulating mechanism. In order to better simulate the rain conditions in the natural environment, reagents of different pH values ​​can be injected through the one-way injection valve, and then output after stirring through the stirring mechanism, so that more accurate test data close to the real environment can be obtained.

[0030] To be more specific, the spray box body 1 is hingedly provided with a box door 101 at both axial ends. The setting of the box door is used for the transportation of test equipment and is also convenient for subsequent observation by the operator. A spray auxiliary pipe 19 is provided on the inner wall of the box door 101. Two groups of spray auxiliary pipes 19 are provided on each side. The spray auxiliary pipe 19 is arranged in an inverted E shape, and the vertical section is arranged downward along the box door 101. In this embodiment, the spray auxiliary pipe is provided on the inner wall of the box door, so as to cooperate with the spray main pipe to form a spray test in five directions. A Y-shaped spray head 16 is also provided on the spray auxiliary pipe 19, and auxiliary pipe connectors 151 are symmetrically provided at both ends of the water storage pipe 15. The auxiliary pipe connector 151 is connected to the connector 191 on the spray auxiliary pipe 19 through a pipeline. The water supply of the spray auxiliary pipe is realized through the water storage pipe, and its spraying time will be slightly later than the spray main pipe, and it will spray synchronously after spraying for a period of time.

[0031] To be more specific, a water storage base 3 is provided at the bottom of the spray box 1, and a rectangular supporting platform 4 is provided in the middle of the water storage base 3. A water tank is provided between the water storage base 3 and the supporting platform 4. The water tank cooperates with the filter 10, and a seepage panel 301 is provided on the surface of the water tank. In this embodiment, since the entire equipment is set on the ground, and the water storage base is set in the installation groove on the ground, the supporting platform is set at the center of the water storage base, and both it and the water storage tank are rectangular structures. A seepage panel with slots is provided on the water tank. The water after spraying flows from the seepage panel into the water tank, and then is filtered through the filter, and the second variable frequency water pump extracts it for circulating water use.

[0032] More specifically, two sets of transport guide rails 17 are symmetrically arranged on the water storage base 3, and four self-driven transport seats 18 are arranged on the transport guide rails 17. The transport guide rails 17 are U-shaped structure guide rails, and the vertical section is the guide rail wall. A matching rack 171 is provided on the top of the inner guide rail wall, and a guide bar 172 is provided on the outer wall of the two sections of the guide rail wall. A proximity switch 25 is provided on the inner wall of the outer guide rail wall near the outlet end. Two drive motors 20 are provided at the bottom of the self-driven transport seat 18, and the output end of the drive motor 20 is connected to a drive gear 21 that meshes with the matching rack 171. A plurality of clamping seats 22 are provided on both sides of the bottom of the automatic drive transport seat 18, and two clamping seats 22 are provided on the clamping seat 22. The holding wheel 23 is rollingly connected to the upper and lower end surfaces of the guide bar 172. The clamping seat 22 is also provided with a horizontal guide wheel 24 rollingly connected to the side of the guide bar 172. A switch trigger bracket 28 is also provided at the bottom of the self-driven transport seat 18. In this embodiment, an automatic conveying system is also provided, that is, the self-driven transport seat cooperates with the transport guide rail to enable the in and out transportation operation of the equipment under the control of the control system. At the same time, an anti-misoperation structure, that is, a proximity switch, is also provided. The proximity switch must be set at the output end. When the self-driven transport seat reaches this position, the switch trigger bracket touches the proximity switch, thereby triggering a stop signal. The control system outputs a stop command and the drive motor stops running, so that the equipment can accurately stay in the test area.

[0033] To be more specific, the control system 26 is a PLC control terminal, which is equipped with a rainfall control module and a flow control module. The control system 26 is electrically connected to the first variable frequency water pump 7, the filter 10, the second variable frequency water pump 11, the drive motor 20, the proximity switch 25, the first flow pressure integrated transmitter 27, and the second flow pressure integrated transmitter 902. In this embodiment, the water flow rate can be specifically controlled by the rainfall control module. Different flow rates per minute correspond to different rainfall modes, and specific choices such as light rain, moderate rain, heavy rain and rainstorm can be achieved, thereby simulating the rain effect test in a real environment and improving the validity of the test data. The setting of the variable frequency water pump is conducive to the smooth transition of the flow rate and reduces the test differences.

[0034] The working principle of the present invention is as follows: before conducting a spray test, the water tank 6 is first filled with water by connecting the external water supply system through the water inlet pipe 601, and the acid and alkaline reagents are injected through the one-way injection valve 602 as needed, and the stirring mechanism is started for stirring. The pH detection device detects the pH value. At this time, the device can be fixed on the self-driving transport seat 18 at the same time, and the drive motor 20 is started through the control system 26 to drive the device to move along the transport guide rail 17. When the switch trigger bracket 28 contacts the proximity switch 25, a stop signal is triggered, the drive motor 20 stops working, and the entire device stays in the test area. , close the door 101 at both ends and start the test. The output water volume can be controlled by the first variable frequency water pump 7. The water enters the water supply pipes 8 on both sides from the diversion pipe 9, and goes up from the spray main pipe 14 and is sprayed from each sprinkler head 16. At the same time, the water converges at the top water storage pipe 15, flows to both ends, and then enters the spray sub-pipe 19 for spraying. Except for the bottom, the equipment as a whole is sprayed from five directions. Because the sprinkler head 16 adopts a Y-shaped setting, the water spraying surfaces of the sprinkler heads 16 on the two adjacent groups of sprinkler main pipes 14 intersect at the edge, and every two sprinkler heads on the same root sprinkler main pipe 14 The water spraying surface also crosses at the edge, thus performing a matrix coverage on the equipment, which can save water while ensuring full coverage, thereby effectively improving the spray test effect. During the spraying process, the first flow and pressure integrated transmitter 27 detects the spray flow and pressure in real time, and the control system 26 can select different rainfall modes according to the test needs, such as light rain and heavy rain. With the spraying time control, the water flow rate can be changed quickly and smoothly in real time. Moreover, since the first flow and pressure integrated transmitter 27 is set for each group of spray main pipes 14, each group of spray main pipes 14 can be operated. The working status is monitored. When any problem occurs in any line, the corresponding position will be displayed on the control system 26, so that the group of pipelines can be repaired in time to avoid affecting the test results. The entire spray system can also recycle water. The used water enters the bottom water storage tank, and the filter 10 is immersed in it. The second variable frequency water pump 11 is started to extract the filtered water, which is transmitted to the water storage pipe 15 through the circulation pipe 13 and circulated back to the spray main pipe 14 again. After the circulating water is filtered by the filter 10, the impurities are filtered out and will not cause blockage to the spray head 16, ensuring the smooth flow of the entire pipeline.
