Description

Technical Field

[0001] The invention relates to the technical field of high-pressure jet waterproof testing, in particular to an IPX9K testing device capable of performing multiple tests continuously and a water circulation control system. Background Art

[0002] The international test standard of IPX9K requires that the temperature of the high-pressure jet water in the test be 80+ / -5 degrees, the water spray flow rate be (15+ / -1)L / min, and the test be conducted at one water spray angle for 30S. One test cycle of four different water spray angles takes a total of 2 minutes. The amount of water required for one test cycle is 30L. If a sample is tested for 30 cycles continuously, nearly 1 ton of water will be required.

[0003] Defects: The waterproof test of automobile parts mainly simulates the various parts of the car, and bears the test of high-temperature and high-pressure water jets from all directions for a certain period of time. After the test, the sealing, electrical properties, insulation, etc. of the samples are required to be the same as before the test.

[0004] In order to solve the above defects, the prior art (application number: 201820782520.6, Chinese patent with authorization announcement date of 2018-12-04) discloses a multi-point spraying device for waterproofing test of automobile parts. During the test, the servo motor is started, and the servo motor drives the turntable to rotate through the rotating shaft, and the turntable drives the fixture to rotate and then drives the automobile parts to rotate. The water supply mechanism is controlled to supply water to the four nozzles in sequence, and each nozzle sprays high-pressure water for a set time at different angles toward the automobile parts through the nozzle to test the waterproof performance of the automobile parts.

[0005] However, the existing box-type IPX9K test device has the following problems:

[0006] (1) There is only one test water tank, which is fixed and inconvenient to clean. The residual water after the test also flows directly back to the water tank. The test water tank will accumulate more and more impurities. These impurities will be sprayed onto the surface of the sample under test together with the high-pressure test water under the action of the booster water pump, causing additional impact on the surface of the sample and affecting the accuracy of the test results.

[0007] (2) The test water tank has a small volume and a slow heating speed. It usually takes about one hour to heat the water in the test water tank from the normal temperature of 25 degrees to the required 80 degrees for the test. Moreover, the capacity of one tank of water is not enough to test two test cycles. After the residual water after the test flows back to the test water tank, or after the tap water is automatically replenished, it takes more than half an hour to heat the water in the test water tank to 80 degrees again. Even if a sample is only tested for one cycle, after testing the first sample, it takes a long time to test the second sample. The detection efficiency is low and cannot meet the testing needs of a large number of tasks in the laboratory.

[0008] (3) In particular, when some new energy vehicles require a test sample to undergo dozens of continuous cycles of simulation tests during the research and development stage, the existing experimental equipment cannot meet the customer's commissioned test requirements, so the above problem needs to be solved urgently.

[0009] Therefore, we proposed an IPX9K test device and water circulation control system that can perform multiple tests continuously in order to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 10 , the present invention provides the following technical solutions: an IPX9K test device and a water circulation control system capable of continuous multiple tests;

[0043] Embodiment 1: In order to solve the problem that the existing test device in the prior art has low detection efficiency and cannot meet the needs of continuous multiple tests, the following solution is disclosed. Figure 1-Figure 6 As shown, it includes a cabinet 1, a 1 / 4 arc-shaped water spray bracket 2 is arranged above the cabinet 1, and the arc-shaped water spray bracket 2 is respectively equipped with spray heads 3 at the positions of 0 degrees, 30 degrees, 60 degrees and 90 degrees.

[0044] A controller 30 is installed on the upper right side of the cabinet 1, a sample support plate 4 is arranged in the middle position above the cabinet 1, a drain hole 7 is opened and fixed on the left side of the top of the cabinet 1, a quick heating box 8 is installed on the left side inside the cabinet 1, and a water pipe 9 is arranged inside the quick heating box 8; a test water tank 16 is installed on the right side inside the cabinet 1, a constant temperature water tank 12 is installed inside the cabinet 1 between the quick heating box 8 and the test water tank 16, a temperature sensor 14 and a liquid level sensor 15 are bolted on the left side of the constant temperature water tank 12 and the test water tank 16, an over-temperature protector 17 is bolted on the upper left side of the test water tank 16, and a heating pipe 13 is bolted inside the quick heating box 8, the constant temperature water tank 12 and the test water tank 16; the cabinet A water pump 39 is installed inside the cabinet 1, and both ends of the water pump 39 are respectively connected to the constant temperature water tank 12 and the test water tank 16 through the second connecting pipe 22. A booster pump 6 and a chiller 18 are installed on the right side of the top of the inner wall of the cabinet 1. The drain hole 7 is arranged in a funnel shape, and the water pipe 9 is spirally arranged inside the rapid heating box 8, and both ends of the water pipe 9 pass through the top and bottom of the rapid heating box 8. One end of the water pipe 9 is connected to the quick connector 10 at the lower end of the drain hole 7, and the other end of the water pipe 9 is fixedly connected to the top of the constant temperature water tank 12. The water inlet end of the booster pump 6 is connected to the water outlet of the test water tank 16 and the chiller 18 through the third connecting pipe 23, and a first connecting pipe 21 is fixedly connected between the chiller 18 and the constant temperature water tank 12.

[0045] When in use, the test personnel place the sample to be tested on the sample support plate 4, and the electric telescopic rod 27 can drive the sample support plate 4 to rise or fall (the electric telescopic rod 27 contains a motor, which generates power after being powered by a power supply, thereby driving the telescopic movement of the telescopic rod). At the same time, the slider 26 slides left and right and front and back in the cross slide 25 to adjust the position of the sample support plate 4. At the same time, the height of the sample support plate 4 can be adjusted so that the distance between the surface of the sample to be tested and the nozzle 3 meets the range specified by the standard, and the water temperature required for the test is set in the controller 30, thereby determining whether the experimental device starts the high-temperature water circulation system or the cold water test system, and setting the flow rate required for the test, and the nozzle 3 at each angle The water spraying time, the total number of test cycles, and the time interval between each cycle. If it is a continuous multiple test, the time interval between each cycle is set to 0. Then, when conducting a high-temperature water test, the water inlet control and heating control requirements of the test water tank 16 are as follows: If the set test cycle is only 1 time, the control system will control the water inlet of the test water tank 16 to 60L to save water and shorten the heating time of the test water, and the controller 30 will also automatically control the rapid heating box 8 and the constant temperature water tank 12 to not work; if the set number of test cycles is 2 or more, the controller 30 will default the water inlet of the test water tank 16 to 100L, so that it can meet the water consumption of multiple cycle tests, and control The controller 30 will automatically control the heating operation of the rapid heating box 8 and the constant temperature water tank 12, as well as the pumping operation of the water pump 39 and the booster pump 6. Moreover, since the rapid heating box 8, the constant temperature water tank 12 and the test water tank 16 are all installed by slide rails, the relevant connections are all connected by a quick connector 10 structure, which is convenient for disassembling and removing these boxes for repair and maintenance. At the same time, the water pipe 9 of the rapid heating box 8 adopts a spiral structure, which makes the path of the recycled water extended several times, and the water pipe 9 is in direct contact with multiple heating pipes 13, and the heating rate is very fast, which can achieve the requirement of the test water temperature for the recycled water from the inlet of the water pipe 9 to the outlet. At the same time, the constant temperature water tank 12 can further control and stabilize the water temperature coming out of the rapid heating box 8. Within the range of water temperature specified in the experiment, when the water from the constant temperature water tank 12 is pumped into the test water tank 16 and mixed with the remaining test water, the water temperature in the test water tank 16 will not exceed the water temperature specified in the test, thereby ensuring the accuracy of the test. At the same time, the capacity of the test water tank 16 is increased to meet the water consumption of three test cycles, and the power of the heating tube 13 of the test water tank 16 is increased, so that the time required to heat the water in the test water tank 16 from normal temperature tap water to the water temperature of 80 degrees required for the test is shortened by more than half. At the same time, this water tank capacity also comprehensively balances the economy of the total amount of test water used, and also balances the economy of power consumption for test water recovery and heating, and enables the water to reliably and effectively meet the circulation of stable water temperature without causing time interruptions.

[0046] Embodiment 2: Different from Embodiment 1, this embodiment uses the temperature sensor 14, liquid level sensor 15, and over-temperature protector 17 to automatically detect the water temperature and water level, thereby improving safety. For details, refer to Figure 1-Figure 6 and Fig. 9 As shown, the bottoms of the rapid heating box 8, the constant temperature water tank 12 and the test water tank 16 are all installed on three U-shaped chutes 11, the water outlet of the booster pump 6 is connected to the pipeline of the nozzle 3, and a pressure gauge 28 and a flow meter 29 are respectively installed, and the electric telescopic rod 27, the pressure gauge 28 and the flow meter 29 are respectively electrically connected to the controller 30, a filter screen 19 is installed inside the drain hole 7 and on the right side inside the test water tank 16, an overflow port 20 is fixed above the right side of the test water tank 16, a liquid inlet pipe 31 is fixed on the right side of the top of the test water tank 16, and a water valve is installed inside the liquid inlet pipe 31, a quick connector 10 is fixed to the lower end of the drain hole 7, the right side of the chiller 18 and the right end of the liquid inlet pipe 31, the heating pipe 13, the temperature sensor 14, the liquid level sensor 15, the over-temperature protector 17 and the water valve are all electrically connected to the controller 30, the booster pump 6, the water pump 39, the rotating motor 38 and the electric telescopic rod 27 are all electrically connected to the controller 30.

[0047] The switching control requirements for high and low temperature test water are as follows: when conducting a high temperature water test, the controller 30 will connect the water valve of the spiral metal water pipe 9 to the chiller 18, and the water valve of the chiller 18 to the booster pump 6, and open the water valve of the spiral metal water pipe 9 to the constant temperature water tank 12. When only one cycle of low temperature water is tested, the controller 30 will close the water valve of the spiral metal water pipe 9 to the chiller 18, and open the water valve of the spiral metal water pipe 9 to the constant temperature water tank 12, so that the chiller 18 after the test can be cooled. The water flows back directly to the constant temperature water tank 12; when conducting multiple cycles of cold water tests, the controller 30 will close the water valve connecting the water outlet of the spiral metal water pipe 9 to the constant temperature water tank 12, and open the water valve connected to the chiller 18, so that the test water can flow back directly to the chiller 18 for recycling; when conducting low temperature water tests, the controller 30 will control the rapid heating box 8 and the heating pipe 13 of the constant temperature water tank 12 not to work; when other types of cold water tests are required to be carried out using other water spray test devices, the controller 30 will connect the water outlet of the spiral metal water pipe 9 to the chiller 1 8, close the water valve connecting the water outlet of the chiller 18 to the water valve of the booster pump 6, and open the water valve of the spare water outlet of the chiller 18 at the same time, so that other water spray test devices can be connected to the spare water outlet of the chiller 18 to perform other types of cold water tests, and then set the above-mentioned related test parameters and click start. The controller 30 will automatically control the water temperature of the test water tank 16, the rapid heating tank 8, and the constant temperature water tank 12 according to the above-mentioned control requirements, so that they automatically meet the test water temperature requirements of the set test cycle number. When the set test cycle is completed, the controller 30 It will sound continuously to remind the operator to deal with it, and automatically shut down the power of all heating tubes 13, water pump 39 and booster pump 6. When a low-temperature water test is required, the controller will switch to the cold water test system according to the above control requirements to conduct the corresponding cold water test conditions. At the same time, the water temperature in the test water tank 16 is controlled within the temperature range required for the test. In the event that the temperature sensor 14 fails and the water temperature reaches a set temperature value above 85 degrees, the over-temperature protector 17 can forcibly cut off the power of the heating tube 13 to prevent the risk of abnormal overheating.

[0048] Embodiment 3: Different from Embodiment 2, this embodiment uses two clamping plates 37 to move relative to each other, which can clamp and fix the automobile parts, and uses suction cups 32 to adsorb and fix the automobile parts, so as to ensure the stability of the automobile parts during the high-pressure water spray test. Figure 1 , Figure 7 , Figure 8 and Fig.10As shown, a rotating shaft 5 is connected through the top of the inner wall of the cabinet 1, and the bottom end of the rotating shaft 5 is fixedly connected to the output end of the rotating motor 38, and a rotating plate 24 is fixed to the top of the rotating shaft 5, and a cross slide 25 is provided on the upper surface of the rotating plate 24, and a slider 26 is slidably connected to the inner wall of the cross slide 25, and an electric telescopic rod 27 is fixed to the top of the slider 26, and the output end of the electric telescopic rod 27 is fixedly connected to the bottom of the sample support plate 4, and the internal bearing of the sample support plate 4 is connected to a bidirectional threaded rod 36, and one end of the bidirectional threaded rod 36 extends out of the right side of the sample support plate 4, and the outer sides of the two ends of the bidirectional threaded rod 36 are sleeved with clamping plates 37, and the upper surface of the sample support plate 4 is installed with suction cups 3 2, and a piston block 33 is arranged inside the suction cup 32, a piston rod 34 is fixedly connected to the bottom of the piston block 33, and gear blocks are installed at equal intervals on the front of the piston rod 34, a driving gear 35 is symmetrically sleeved and fixed on the outer side of the two-way threaded rod 36, and the threads on the outer sides of the two ends of the two-way threaded rod 36 are in opposite directions, the two clamping plates 37 and the two-way threaded rod 36 are threadedly connected, and the bottom of the clamping plates 37 and the inner wall of the sample support plate 4 are in sliding connection, the outer side of the piston block 33 and the inside of the suction cup 32 are sealed and slidably connected, the bottom of the piston rod 34 passes through the bottom of the suction cup 32 and the inside of the sample support plate 4, and the multiple gear blocks on the piston rod 34 are meshed with the driving gear 35.

[0049] The sample to be tested is placed on the two suction cups 32 on the test sample support plate 4, and the two-way threaded rod 36 is manually rotated to make the two clamping plates 37 move relative to each other and clamp and fix the automobile parts. At the same time, the active gear 35 rotates and drives the meshing piston rod 34 to move downward, so that the piston block 33 moves downward inside the suction cup 32. At this time, the two suction cups 32 generate negative pressure and adsorb and fix the automobile parts, thereby ensuring the stability of the automobile parts during the high-pressure water spraying test.
