Description

Technical Field

[0001] This application relates to the field of clothing performance detection, and in particular to a meteorological rain shower test system. Background Art

[0002] The meteorological rain shower test system tests the rainproof performance of clothing by simulating the natural rain environment. At present, the test standards for clothing rain shower performance in European standards and national standards are different, and the existing meteorological rain shower test systems can only be individually adapted to the tests of European standards or national standards. Utility Model Content

[0003] In order to simultaneously meet the clothing rain shower test requirements of European standards and national standards, this application provides a meteorological rain shower test system.

[0004] A meteorological rain shower test system provided by this application adopts the following technical solutions:

[0005] A meteorological rain shower test system includes a test chamber, a clothes hanging device located in the test chamber, a spray device located above the test chamber, and a water delivery device for controlling water intake.

[0006] The clothes hanging device is used to hang the clothes to be tested.

[0007] The spray device includes a rainwater pool located at the top of the test chamber, and the rainwater pool is provided with an overflow port 45 mm from the bottom.

[0008] The water delivery device is used to control the amount of water delivered to the rainwater pool per unit time.

[0009] By adopting the above technical solutions, when performing European standard detection, a large amount of water is delivered into the rainwater pool so that the liquid level height in the rainwater pool is always maintained at 45 ± 5 mm, meeting the European standard detection requirements. When performing national standard detection, the water delivery device controls the amount of water delivered to the rainwater pool per unit time to meet the national standard detection requirements. Therefore, the solution of this application can be used for both European standard detection and national standard detection.

[0010] Preferably, it further includes spray pipes on the left and right sides of the dummy model.

[0011] By adopting the above technical solutions, the situation of wind and rain is simulated through the spray pipes on both sides.

[0012] Preferably, the spray device further includes a water receiving tray. The height position of the water receiving tray is lower than that of the rainwater pool. The water receiving tray is provided with a linear power element for driving it to move back and forth. The water receiving tray has two position states, namely a water receiving position at the bottom of the rainwater pool and a non-water receiving position away from the bottom of the rainwater pool.

[0013] By adopting the above technical solution, when it is not necessary to simulate rainwater at the top, the water receiving tray is moved to the water receiving position to avoid rainwater dripping from the top and interfering with the detection.

[0014] Preferably, the rainwater pool is 5000 mm above the ground, and 600 - 800 rain holes with a diameter of 0.6 mm are provided at the bottom of the rainwater pool.

[0015] Preferably, the water delivery device includes a water supply station and a water intake control console. The water supply station includes a water tank.

The other end of the European standard rain shower cut-off valve is connected to a European standard rain shower water pipe and is communicated with the rainwater pool.

[0016] By adopting the above technical solution, large particle impurities are filtered through the filter joint. When performing European standard detection, the European standard rain shower cut-off valve is opened, and the pressure reducing valve for water distribution is closed. At this time, water is directly delivered to the rainwater pool through the European standard rain shower water pipe, so that the water in the rainwater pool is maintained at a height of 45 ± 5 mm for simulated rainwater testing, meeting the requirements of European standard detection.

[0017] Preferably, the other end of the double-standard three-way pipe is communicated with a four-way pipe. The other three joints of the four-way pipe are respectively connected to a water pressure transmitter, a water outlet pipe, and a first return pipe. The other end of the first return pipe is communicated with the water tank, and a protection solenoid valve is installed on the first return pipe.

[0018] By adopting the above technical solution, the water pressure transmitter is used to detect the water pressure. When the water pressure is less than or equal to the second preset value, the protection solenoid valve is closed; when the water pressure is greater than the second preset value, the protection solenoid valve is opened, so that the water pressure can be relieved through the first return pipe to avoid excessive water pressure.

[0019] Preferably, the other end of the water outlet pipe is connected to a pressure reducing valve for water distribution. An overflow valve and a second return pipe are respectively connected to the water outlet pipe. The overflow port of the overflow valve and the other end of the second return pipe are both communicated with the water tank, and a flow control solenoid valve is installed on the second return pipe.

[0020] By adopting the above technical solution, the water pressure transmitter is used to detect the water pressure. When the water pressure is less than or equal to the first preset value, the protection solenoid valve and the flow control solenoid valve are closed; when the water pressure is greater than the first preset value and less than or equal to the second preset value, the flow control solenoid valve is opened and the protection solenoid valve is closed; when the water pressure is greater than the second preset value, the protection solenoid valve and the flow control solenoid valve are opened.

[0021] Preferably, the other end of the pressure reducing valve for water separation is connected with four branch pipes, namely a side spray pipe, a light rain simulation pipe, a heavy rain simulation pipe and a rainstorm simulation pipe. A side spray solenoid valve is installed on the side spray pipe, a light rain solenoid valve is installed on the light rain simulation pipe, a heavy rain solenoid valve is installed on the heavy rain simulation pipe, and a rainstorm solenoid valve is installed on the rainstorm simulation pipe.

[0022] Preferably, the water intake control console includes a flowmeter mounting plate, and a right side spray flowmeter, a left side spray flowmeter, a light rain flowmeter, a heavy rain flowmeter and a rainstorm flowmeter located on the flowmeter mounting plate. The water inlets of the side spray flowmeter and the left side spray flowmeter are both connected to the side spray pipe, and the water inlets of the light rain flowmeter, the heavy rain flowmeter and the rainstorm flowmeter are respectively connected to the light rain simulation pipe, the heavy rain simulation pipe and the rainstorm simulation pipe. The water outlets of the right side spray flowmeter and the left side spray flowmeter are connected to the spray pipe, and the water outlets of the light rain flowmeter, the heavy rain flowmeter and the rainstorm flowmeter are all connected to the rainwater pool.

[0023] Preferably, the clothes hanging device includes a rotating table base, a rotating disk rotatably connected above the rotating table base, a dummy model located above the rotating disk, and a rotating drive assembly for driving the rotating disk to rotate.

[0024] By adopting the above technical solution, the dummy model on the rotating disk is driven by the rotating drive member to rotate, so as to simulate the situation of being affected by rain in multiple directions.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When performing European standard detection, a large amount of water is conveyed into the rainwater pool, so that the liquid level height in the rainwater pool is always maintained at 45 ± 5 mm, meeting the requirements of European standard detection. When performing national standard detection, the amount of water conveyed to the rainwater pool per unit time is controlled by the water conveying device, meeting the requirements of national standard detection. Therefore, the solution of the present application can be used for both European standard detection and national standard detection. BRIEF DESCRIPTION OF THE DRAWINGS
