Description

Technical Field

[0001] The invention belongs to the technical field of reliability test equipment, and particularly relates to an ice-water impact test chamber. Background Art

[0002] The ice-water impact test chamber is an existing reliability test equipment. The ice-water impact test is a performance test that simulates the extremely cold environment in winter when ice water splashes onto the heating system or components when driving on a wet road surface. It can also be applied to the performance tests of other automotive parts, raw materials, and devices.

[0003] For a relatively traditional ice-water impact test equipment, such as an ice-water impact test chamber described in the existing patent CN201720641409.0, it conducts tests by spraying ice water on the test piece through a nozzle. With the improvement of test requirements, the current ice-water impact test not only includes ice-water spraying tests but also ice-water immersion tests. In order to integrate the two tests, we propose an ice-water impact test chamber. By storing the ice water during the spraying test in the water storage gap formed between the bottom of the ice water tank and the bottom of the immersion chamber, and storing the ice water during the immersion test in the ice water tank, the ice water used in the spraying test and the ice water used in the immersion test can be separated from each other. At the same time, during the spraying test, the sprayed ice water will not enter the ice water tank, avoiding the change in the temperature of the ice water inside the ice water tank caused by the sprayed ice water.

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1:

[0032] As Figures 1 to 5An ice-water impact test chamber shown in the figure includes an outer box body 100, an inner box body 101 and a refrigeration unit 102. The inner box body 101 and the refrigeration unit 102 are both placed inside the outer box body 100. At the corners of the inner box body 101, connecting ribs 103 are fixedly arranged, and a ring-shaped rectangular platform 104 is fixedly connected by all the connecting ribs 103. The inner box body 101 is divided into a spraying chamber 105 and an immersion chamber 106 up and down through the ring-shaped rectangular platform 104. A water leakage gap is formed between each side of the ring-shaped rectangular platform 104 and the inner wall of each side of the inner box body 101.

[0033] A spraying mechanism and a basket mechanism are arranged in the spraying chamber 105. The basket mechanism includes a lifting drive device 107, a basket 108 and a frame 109. The lifting drive device 107 is used to drive the frame 109 to move up and down. The basket 108 is fixedly arranged on the lower side of the frame 109. A first sealing plate 110 which is slidably sealed with the inner side of the ring-shaped rectangular platform 104 is also fixedly arranged at the bottom of the frame 109. The upper surface of the ring-shaped rectangular platform 104 and the upper surface of the first sealing plate 110 are jointly processed into an inclined structure which slopes from the center of the ring-shaped rectangular platform 104 to each side from top to bottom. A second sealing plate 111 is also arranged at the top of the frame 109. An ice water tank 112 is arranged in the immersion chamber 106. The upper side of the ice water tank 112 is an opening which matches the basket mechanism. The ice water tank 112 is suspended, and a water storage gap is formed between the bottom of the ice water tank 112 and the bottom of the immersion chamber 106. The spraying mechanism is communicated with the bottom of the immersion chamber 106. The bottom of the ice water tank 112 and the bottom of the immersion chamber 106 are respectively communicated with the refrigeration unit 102 through a connecting pipe 113.

[0034] The ring-shaped rectangular platform 104 can be fixed in the inner box body 101 through the connecting ribs 103, so as to separate the spraying chamber 105 and the immersion chamber 106, and the formed water leakage gap can leak water downward; the frame 109 is used to install the basket 108, and the frame 109 can be driven by the lifting drive device 107, so that the basket 108 moves up and down into the spraying chamber 105 and the immersion chamber 106; when the basket 108 rises completely to the spraying chamber 105 for an ice-water spraying test, the first sealing plate 110 can seal the inner side of the ring-shaped rectangular platform 104; when the basket 108 descends completely to the ice water tank 112 in the immersion chamber 106 for an ice-water immersion test, the second sealing plate 111 can seal the inner side of the ring-shaped rectangular platform 104;

[0035] Water is injected into the ice water tank 112, and at the same time, water is injected into the water storage gap formed between the bottom of the ice water tank 112 and the bottom of the immersion chamber 106. After being communicated with the refrigeration unit 102 through the connecting pipe 113, the refrigeration unit 102 can cool the water into ice water, and the spraying mechanism sprays the ice water in the water storage gap between the bottom of the ice water tank 112 and the bottom of the immersion chamber 106.

[0036] In the specific use process, the following steps are included:

[0037] Step ①: First, cool the water in the water storage gap between the bottom of the ice water tank 112 and the bottom of the soaking chamber 106 to between 0°C and 4°C through the refrigeration unit 102, and cool the water in the ice water tank 112 to between 0°C and 4°C.

[0038] Step ②: Conduct a spraying test. Drive the basket mechanism to rise completely to the spraying chamber 105 through the lifting drive device 107. At this time, as shown in Figure 3 and Figure 5 , the basket 108 is in the spraying chamber 105, and the first sealing plate 110 at the bottom of the frame 109 seals the inside of the ring rectangular table 104. People put the test piece into the basket 108.

[0039] Step ③: Spray the ice water in the water storage gap between the bottom of the ice water tank 112 and the bottom of the soaking chamber 106 onto the test piece in the basket 108 through the spraying mechanism. Since the first sealing plate 110 seals the inside of the ring rectangular table 104, and at the same time, since the upper surface of the ring rectangular table 104 and the upper surface of the first sealing plate 110 are jointly processed into an inclined structure that slopes downward from the center of the ring rectangular table 104 to each side, the sprayed ice water will not enter the ice water tank 112, but will flow along the inclined structures of the upper surface of the ring rectangular table 104 and the upper surface of the first sealing plate 110, and reflow into the water storage gap between the bottom of the ice water tank 112 and the bottom of the soaking chamber 106 through the water leakage gaps formed between the sides of the ring rectangular table 104 and the inner walls of the sides of the inner box body 101. Thus, during the spraying process, the ice water can be recycled, and at the same time, the refrigeration unit 102 can cool the ice water to ensure that the ice water maintains its temperature during the spraying cycle.

[0040] Step ④: Conduct a soaking test. Drive the basket mechanism to descend completely to the ice water tank 112 through the lifting drive device 107. The second sealing plate 111 seals the inside of the ring rectangular table 104, so that the test piece is completely immersed in the ice water tank 112 for an ice water soaking test.

[0041] Step ⑤: Drive the basket mechanism to rise and fall periodically through the lifting drive device 107, and then the spraying test and the soaking test on the test piece can be carried out reciprocally.

[0042] In this embodiment, by storing the ice water during the spraying test in the water storage gap formed between the bottom of the ice water tank 112 and the bottom of the soaking chamber 106, and storing the ice water during the soaking test in the ice water tank 112, the ice water used in the spraying test and the ice water used in the soaking test can be separated from each other. At the same time, during the spraying test, the sprayed ice water will not enter the ice water tank 112, avoiding the change in the temperature of the ice water inside the ice water tank 112 caused by the sprayed ice water.

[0043] In this embodiment, the spraying mechanism is further described. As shown inFigure 3 and Figure 4 As shown in Figure 4 , the spraying mechanism includes a water pump box 114, a connecting hose 115, a spray head 116 and an adjusting member. The input end of the water pump box 114 is communicated with the bottom pipeline of the soaking chamber 106, the output end of the water pump box 114 penetrates through the spraying chamber 105 and is communicated with the connecting hose 115 through a pipeline, the connecting hose 115 is connected with the spray head 116, and the adjusting member is used to adjust the height of the spray head 116. The spray head 116 is of a flat head triangular structure and is provided with a strip-shaped water spraying port 117 arranged horizontally. The adjusting member includes a mounting plate 118 and a T-shaped connecting plate 119. The mounting plate 118 is provided with a strip-shaped sliding groove, and the T-shaped connecting plate 119 is provided with a locking bolt 120 that is slidably matched with the strip-shaped sliding groove. The connecting hose 115 is fixed to the T-shaped connecting plate 119.

[0044] During the implementation of step ②, the height of the spraying mechanism can also be adjusted through the adjusting member. Specifically, by loosening the locking bolt 120 and then moving the locking bolt 120 to slide in the strip-shaped sliding groove of the mounting plate 118, the T-shaped connecting plate 119 can be made to pull the connecting hose 115 and the spray head 116, thereby adjusting the position of the spray head 116. After the adjustment is in place, the locking bolt 120 is tightened again to fix the T-shaped connecting plate 119 and the mounting plate 118.

[0045] When the spraying mechanism sprays in step ③, the water pump box 114 is started to pump the ice water in the water storage gap between the bottom of the ice water tank 112 and the bottom of the soaking chamber 106 into the connecting hose 115 and sprayed out by the spray head 116. Since the spray head 116 is of a flat head triangular structure and is provided with a strip-shaped water spraying port 117, the range of the ice water sprayed by the spray head 116 is wider, and by changing the pump water pressure of the water pump box 114, the ice water sprayed by the spray head 116 can form a wave shape.

[0046] Embodiment 2:

[0047] On the basis of Embodiment 1, the ice water tank 112 is further improved. As Figure 6 shown, a floating plate 200 is arranged on the water surface of the ice water tank 112. The floating plate 200 is slidably sealed with the ice water tank 112. A plurality of communicating pipes 201 are further installed on the outer side of the ice water tank 112. The lower ends of the communicating pipes 201 are communicated with the bottom of the ice water tank 112, the upper ends of the communicating pipes 201 are communicated with the upper side of the ice water tank 100, and the floating plate 200 is located between the upper and lower ends of the communicating pipes 201.

[0048] The floating plate 200 can float on the water surface of the ice water tank 112. During the process of step ④, the first sealing plate 110 on the lower side of the basket mechanism will push the floating plate 200 downward. During the downward movement of the floating plate 200, the floating plate 200 will let the ice water in the ice water tank 112 flow out from the bottom of the ice water tank 112 to the upper side of the ice water tank 112 through each connecting pipe 201. When the ice water flows out through each flow pipe 201, multiple spray water columns will be formed, thereby conducting a secondary spray test on the specimen and improving the effect of the spray test. Until the floating plate 200 is pushed by the first sealing plate 110 of the basket mechanism to the bottom of the ice water tank 112, the ice water in the ice water tank 112 will then all be injected to the upper side of the first sealing plate 110 through each connecting pipe 201, and the specimen will be subjected to an immersion test with the ice water in the ice water tank 112;

[0049] After the immersion test is completed, when the basket mechanism rises back to the spray chamber 105, the first sealing plate 110 will push the ice water in the ice water tank 112 upward again, and the ice water will flow back to the bottom of the ice water tank 112 through each connecting pipe 201, causing the floating plate 200 to float again.

[0050] As a further optimization of this embodiment, as Figure 6 shown, temperature probes 202 are installed on the lower side of the floating plate 200 and at the bottom of the immersion chamber 106. A protective frame 203 is fixedly arranged on the lower side of the floating plate 200, and the temperature probe 202 on the lower side of the floating plate 200 is installed in the protective frame 203.

[0051] The provided temperature probe 202 is used to monitor the temperature of the ice water in the ice water tank 112 and the temperature of the ice water stored in the water storage gap formed between the bottom of the ice water tank 112 and the bottom of the immersion chamber 106. When the basket mechanism does not enter the ice water tank 112, the floating plate 200 floats on the ice water surface, and the lower temperature probe 202 is used to monitor the temperature of the ice water in the ice water tank 112. When the basket mechanism descends into the ice water tank 112, the protective frame 203 on the lower side of the floating plate 200 is used to protect the temperature probe 202 from being crushed.

[0052] Embodiment Three:

[0053] On the basis of Embodiment Two, for further optimization, as Figure 7 shown, a ring-shaped rectangular mounting plate 300 is arranged on the upper side of the ice water tank 112, and the ring-shaped rectangular mounting plate 300 is bolted and fixed to the bottom of the ring-shaped rectangular platform 104; by arranging the ring-shaped rectangular mounting plate 300, the upper side of the ice water tank 112 can be bolted and fixed to the bottom of the ring-shaped rectangular platform 104, thereby facilitating installation and disassembly.

[0054] The spray chamber 105, the immersion chamber 106 and the ice water tank 112 are all detachably connected with a sealed viewing window 301, and the outer box body 100 is respectively provided with inspection doors 302 corresponding to the spray chamber 105 and the immersion chamber 106; people can view the test conditions in the spray chamber 105, the immersion chamber 106 and the ice water tank 112 through the sealed viewing window 301 by opening the inspection doors 302 provided on the outer box body 100, and the sealed viewing window 301 is detachably connected and can be removed during maintenance and cleaning, so that people can clean the interiors of the spray chamber 105, the immersion chamber 106 and the ice water tank 112.
