Description

Technical Field

[0001] This utility model belongs to the field of protective clothing testing, and specifically relates to a high-energy raindrop impact testing device for protective clothing. Background Technology

[0002] Currently, my country has a huge number of outdoor workers, spanning numerous industries such as construction, transportation, power, and municipal services. These include construction workers, building repairmen, road maintenance workers, drainage cleaners, sanitation workers, delivery and courier workers, and various emergency personnel who also need to work outdoors in rainy environments to ensure city operations or perform emergency rescue missions. Precipitation (rain, snow, fog) in outdoor working environments poses challenges to the life, safety, and health of these workers. Unprotected workers in rainy environments may suffer injuries due to cold stress, such as hypothermia, frostbite, hypothermia, or adverse reactions. Slowing down can lead to injuries due to the inability to complete tasks safely. Cold stress usually occurs in very low-temperature environments, but when precipitation makes the environment humid and clothing wet, coupled with strong winds that often accompany precipitation, it can cause cold stress injuries to unprotected personnel at even lower temperatures. In recent years, there have even been several cases of outdoor hypothermia in summer in my country. Providing protection for these workers with occupational rainproof clothing is crucial. Due to the key role of occupational rainproof clothing in work and emergency rescue, it has been included in my country's national standard for emergency supplies allocation coding.

[0003] However, when existing protective suits are tested for rain impact, they are usually sprayed directly onto the protective suits with water guns to observe their waterproof performance. However, the fixed-point spraying of water guns cannot simulate the rain conditions in real environmental conditions, and the test results are not accurate.

[0004] Therefore, given the shortcomings of the above solutions in actual manufacturing and implementation, a high-energy raindrop impact testing device for protective clothing is provided to solve the problem that the existing methods generally involve spraying water directly onto the protective clothing with a water gun to observe its waterproof performance, but the fixed-point spraying of the water gun cannot simulate the rain conditions in real environment, and the test results are not accurate. Utility Model Content

[0009] The bottom of the water storage tank is fixedly connected to a side plate assembly with a sliding groove. A displacement assembly is slidably connected inside the sliding groove. A gear assembly that meshes with the drive wheel is fixedly connected to the outside of the displacement assembly. Two slider assemblies with protruding structures are fixedly connected to the outside of each displacement assembly in opposite directions. A water shield for sealing the water outlet at the bottom of the nozzle assembly is also fixedly connected to the inside of every two longitudinally adjacent displacement assemblies.

[0010] In a preferred embodiment, a windproof box for placing a dummy and storing water is fixedly connected to the top surface of the ground.

[0011] In one preferred embodiment, the support components are provided in four locations, with each pair of laterally adjacent support components forming a group.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-6 As shown, a high-energy raindrop impact testing device for protective clothing includes: a ground 1, a support component 1011 fixedly connected to the top surface of the ground 1, a water storage tank 2 fixedly connected to the inner side of the support component 1011, and an installation mechanism 3 fixedly connected to the outer side of the water storage tank 2.

[0031] The installation mechanism 3 is internally fixedly connected to an inlet pipe 301 for introducing water into the water storage tank 2. The bottom end of the inlet pipe 301 is fixedly connected to an inlet flange 3011 for connecting to an external pipeline. The outside of the inlet pipe 301 is fixedly connected to a solenoid valve 3012 for controlling the flow of water.

[0032] An installation plate 3013 is fixedly connected to the outside of the water storage tank 2. Every two longitudinally adjacent installation plates 3013 form a group. A servo motor 3014 is provided at the top of each group of installation plates 3013. An output shaft is provided at the bottom of the servo motor 3014. The output shaft is connected to the drive wheel 3015.

[0033] The bottom of the water storage tank 2 is fixedly connected to a side plate assembly 201 with a sliding groove. A displacement assembly 3016 is slidably connected inside the sliding groove. A gear assembly 3017 that meshes with the drive wheel 3015 is fixedly connected to the outside of the displacement assembly 3016. Two slider assemblies 3018 with protruding structures are fixedly connected to the outside of each displacement assembly 3016 in opposite directions. A water shield 3019 for sealing the water outlet at the bottom of the nozzle assembly 2011 is also fixedly connected to the inside of every two longitudinally adjacent displacement assemblies 3016. A digital display screen 2013 for displaying the temperature data detected by the temperature probe 2012 is fixedly connected to the front of the water storage tank 2.

[0034] Among them, a windproof box 101 for placing a dummy and storing water is fixedly connected to the top surface of the ground 1. There are four support components 1011 in total, and each pair of horizontally adjacent support components 1011 forms a group.

[0035] Among them, two sets of support components 1011 are fixedly connected to the front and rear sides of the top surface of the ground 1, and two side plate components 201 are provided, which are fixedly connected to the left and right sides of the bottom surface of the water storage tank 2.

[0036] The water storage tank 2 has a rectangular array of nozzle assemblies 2011 fixedly connected inside, and the nozzle assemblies 2011 are connected to the water storage tank 2. A temperature probe 2012 for monitoring water temperature is fixedly connected inside the water storage tank 2.

[0037] In use, first, the protective suit to be tested is put on the dummy placed in the windproof box 101. The ground 1 serves as the basic support for the entire device. The four support components 1011 on its top surface are connected in pairs to the front and rear sides of the top surface of the ground 1, which stably support the water storage tank 2. The installation mechanism 3 is fixed on the outside of the water storage tank 2. The water inlet pipe 301 is connected to the external water source pipeline through the water inlet flange 3011. When the solenoid valve 3012 is opened, water flows into the water storage tank 2 through the water inlet pipe 301. The nozzle assembly 2011, which is arranged in a rectangular array inside the water storage tank 2, is connected to the water storage tank 2, and water will flow into the nozzle assembly 2011.

[0038] The test dummy should wear appropriately sized test underwear for clothing testing. The size of the clothing should match the dummy. Zippers, buttons, pockets, etc., should be fastened to simulate normal use. The drawstring at the hem of the jacket should be tightened. If the clothing has a hood, it should be placed over the dummy's head in a normal wearing posture, and the drawstring should be tightened. If the clothing does not have a hood, the dummy's head should be covered with a plastic bag or other waterproof material to prevent water from entering the clothing from the head. However, the plastic bag should not cover the seams at the shoulders and collar. If water is found to enter the clothing from the dummy's face or through the hood during the test, the hood should be removed, and the head should be covered with a plastic bag. The test should be repeated, and the data and phenomena recorded. If the pant legs are adjustable, they should be adjusted to the tightest position. The cuffs and pant legs of the test underwear should be adjusted to about 45 mm above the ends of the test sample's top and pant legs to prevent water from seeping into the underwear at the wrists or ankles.

[0039] The mounting plates 3013 on the outside of the water storage tank 2 are arranged in pairs longitudinally. The servo motor 3014 at the top of each set of mounting plates 3013 is started. The output shaft at the bottom of the servo motor 3014 drives the drive wheel 3015 to rotate. The drive wheel 3015 meshes with the toothed assembly 3017 on the outside of the displacement assembly 3016. Since the displacement assembly 3016 is located in the slide groove of the side plate assembly 201, and the slider assembly 3018 on the outside of the displacement assembly 3016 cooperates with the slide groove, the displacement assembly 3016 slides stably. When the drive wheel 3015 rotates, it drives the displacement assembly 3016 to move in the slide groove of the side plate assembly 201 through the toothed assembly 3017.

[0040] After temperature and humidity conditioning, the test underwear and samples were worn on a simulated dummy. Temperature and humidity conditioning was carried out under standard atmospheric conditions according to the method specified in GB / T6529. The back of the water tank 2 was filled with an appropriate volume of water (e.g., 100L) by connecting the water inlet flange 3011 of the water inlet pipe 301 to an external water pump and opening the solenoid valve 3012 to supply water. After the water tank was filled (water flowed out of the water tank), the water shield was opened for testing. The opening method was that every two longitudinally adjacent displacement components 30 The water shield 3019 connected to the inner side of 16 will move with the movement of the displacement component 3016. When the displacement component 3016 moves to the appropriate position and the water shield 3019 no longer closes the water outlet at the bottom of the nozzle component 2011, the water in the nozzle component 2011 will spray out to simulate raindrops impacting the protective clothing. By controlling the rotation direction and speed of the servo motor 3014, the moving speed and position of the displacement component 3016 can be changed, thereby adjusting the number and position of the opening and closing of the water outlet of the nozzle component 2011 to realize the simulation of different rainfall modes.

[0041] The test lasts for 1 hour. After the test, wait 2 minutes to avoid water on the surface of the clothing affecting the test results. Then, remove the test garment from the mannequin, taking care to avoid water droplets on the underwear. Use appropriate methods to test the area of ​​water stains on the underwear, accurate to one square centimeter. The test should be conducted using at least two garments of the same size, and the average value of the test results should be used as the final result. If a garment fails the test, it should be tested again, and the result should be recorded in the report.

[0042] During the test, the temperature probe 2012 inside the water storage tank 2 monitors the water temperature in real time, and the monitoring data is transmitted to the digital display screen 2013 at the front end of the water storage tank 2 for display, so that the operators can understand the water temperature at any time. Water temperature is also a factor affecting the performance of protective clothing. Rainwater at different water temperatures may have different impact effects on protective clothing. By monitoring the water temperature, the performance of protective clothing can be evaluated more comprehensively.

[0043] The windproof box 101 and the water storage tank 2 can be connected by a water pipe. The water used after testing in the windproof box 101 can be pumped back into the water storage tank 2 for subsequent testing and reuse, so as to achieve the purpose of water conservation.
