Description

Technical Field

[0001] This utility model relates to the field of material simulation application experimental technology, and in particular to an environmental simulation testing device for composite material products. Background Technology

[0002] As a high-precision device, aircraft have high requirements for the materials used in their various components. The entire aircraft material system needs to meet comprehensive performance requirements such as lightweight, high strength, and resistance to extreme environments. Therefore, some components need to use various advanced composite materials, such as polymer-based composite materials and ceramic-based composite materials.

[0003] The requirement for aircraft materials to withstand extreme environments is related to the aircraft's own operating environment. Aircraft fly at high altitudes and generally need to withstand strong convective air currents. Sometimes they also fly in clouds and are subject to impacts from hail and icy rain. These extreme environmental characteristics put great challenges to the materials used in aircraft.

[0004] Therefore, it is necessary to test the performance and quality of composite materials before their application in aircraft. To ensure the validity of the test results, it is necessary to simulate the actual working environment of aircraft as closely as possible. However, simulating extreme high-altitude environments in a small laboratory is quite difficult. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an environmental simulation testing device for composite material products, so as to solve the technical problem in the prior art of how to simulate the extreme high-altitude environment as closely as possible in a small laboratory.

[0006] To achieve the above objectives, this utility model provides an environmental simulation testing device for composite material products, including a testing chamber for simulating extreme high-altitude environments. The testing chamber contains a mounting base for mounting and positioning the product to be tested. The environmental simulation testing device further includes: A mixing chamber is located on the left and right sides of the testing box. The inner side of the mixing chamber is open and communicates with the inner cavity of the testing box, while an air inlet pipe is connected to the outer side of the mixing chamber. The outer end of the air inlet pipe is connected to an external fan. An ice slag funnel is fixedly connected to the top of the testing box. The bottom of the ice slag funnel is equipped with a crusher, and the lower end of the ice slag funnel has an opening that communicates with the mixing chamber. The exhaust chambers located on the left and right sides of the testing chamber are used to exhaust the airflow inside the testing chamber.

[0007] Furthermore, a filter plate is fixedly connected to the inner opening of the mixing chamber, and the filter plate is provided with several uniformly arranged through holes.

[0008] Furthermore, an ice-blocking net is fixedly installed at the inner opening of the exhaust chamber. The ice-blocking net has several evenly arranged through holes, and the diameter of the through holes on the ice-blocking net is smaller than the diameter of the through holes on the filter plate.

[0009] Furthermore, an air extraction pipe is connected to the side wall of the exhaust chamber, and the outer end of the air extraction pipe is connected to an external air extraction machine.

[0010] Furthermore, the front of the testing box is provided with a door, while the back of the testing box is provided with a slag discharge drawer, which is slidably connected to the bottom of the testing box.

[0011] Furthermore, the bottom of the filter plate is provided with a groove, and the mounting base is suspended in the detection box by the bottom support, and the height of the mounting base is above the groove.

[0012] Furthermore, a drain pipe is connected to the bottom of the testing box, and a filter screen is installed at the connection port of the drain pipe.

[0013] The beneficial effects of this utility model are as follows: 1. A testing chamber for simulating extreme high-altitude environments is provided, and the testing chamber is completely sealed to avoid external interference. An air inlet pipe and an exhaust pipe are respectively installed on the left and right sides of the testing chamber, and the air inlet pipe and exhaust pipe are connected to an external fan and exhaust fan, respectively, to simulate high-speed airflow within the testing chamber and to adjust the air pressure inside the testing chamber, making the environment inside the testing chamber closer to the real extreme high-altitude environment.

[0014] 2. A mixing chamber is set up between the air inlet duct and the detection box. An ice slag funnel is set up on the mixing chamber and a crusher is set up at the bottom of the ice slag funnel. Therefore, ice slag or small ice cubes can be mixed into the mixing chamber and these ice slag are filled into the detection box along with the high-speed airflow, thereby simulating the environment inside the high-altitude cloud layer.

[0015] 3. A filter plate is installed at the inner opening of the mixing chamber to prevent excessively large ice blocks from entering the testing chamber and damaging the products being tested. Additionally, a trough is provided at the bottom of the filter plate to allow large ice blocks to fall into the testing chamber. Furthermore, a finer ice-blocking mesh is installed at the inner opening of the exhaust chamber to trap ice fragments or small ice blocks within the testing chamber. Finally, after testing, these ice fragments and blocks are removed through the slag discharge drawer for reuse, minimizing waste. Attached Figure Description

[0025] The first aspect of the utility model, such as Figure 1 , Figure 2 and Figure 3As shown, aircraft fly at high altitudes and generally need to withstand strong convective air currents. Sometimes they also fly in clouds and are subject to impacts from hail and freezing rain. These extreme environmental characteristics put great pressure on the materials used in aircraft. Therefore, before the application of composite materials in aircraft, their performance and quality need to be tested. The purpose of this invention is to simulate the extreme high-altitude environment as much as possible to test the composite material product 01.

[0026] Specifically, a testing chamber 101 is provided, and a mounting base 103 is provided inside the testing chamber 101 for mounting and positioning the product 01 to be tested. The testing chamber 101 is completely sealed to avoid external interference, and a temperature regulation module is also provided on the testing chamber 101 to regulate the temperature inside the testing chamber 101.

[0027] A mixing chamber 104 is provided on one side of the testing chamber 101. The inner side of the mixing chamber 104 is open and communicates with the inner cavity of the testing chamber 101. An air inlet pipe 105 is connected to the outer side of the mixing chamber 104, and the outer end of the air inlet pipe 105 is connected to an external fan. An exhaust chamber 110 is located on the other side of the testing chamber 101 to exhaust the airflow inside the testing chamber 101. An exhaust pipe 112 is also connected to the side wall of the exhaust chamber 110, and the outer end of the exhaust pipe 112 is connected to an external exhaust fan.

[0028] An air inlet pipe 105 and an air extraction pipe 112 are respectively installed on the left and right sides of the test chamber 101. The air inlet pipe 105 and the air extraction pipe 112 are connected to an external fan and an external air extraction fan, respectively. They are used to simulate high-speed airflow in the test chamber 101 and to adjust the air pressure inside the test chamber 101 so that the environment inside the test chamber 101 is closer to the actual high-altitude extreme environment.

[0029] In addition, an ice slag funnel 106 is fixedly connected to the top of the testing box 101. A crusher 107 is provided at the bottom of the ice slag funnel 106, and the lower end of the ice slag funnel 106 has an opening that communicates with the mixing chamber 104.

[0030] Therefore, ice shavings or small ice cubes can be mixed into the mixing chamber 104, and these ice shavings can be filled into the detection chamber 101 along with the high-speed airflow, thereby simulating the environment inside the high-altitude cloud layer.

[0031] The second aspect of this utility model is as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in order to reduce consumption and lower costs, a filter plate 108 is fixedly connected to the inner opening of the mixing chamber 104 in this embodiment. The filter plate 108 has a plurality of evenly arranged through holes. An ice-blocking net 111 is fixedly installed at the inner opening of the exhaust chamber 110. The ice-blocking net 111 has a plurality of evenly arranged through holes, and the diameter of the through holes on the ice-blocking net 111 is smaller than the diameter of the through holes on the filter plate 108.

[0032] Preferably, the bottom of the filter plate 108 is provided with a groove 109, and the mounting base 103 is suspended in the test box 101 by the bottom support, and the height of the mounting base 103 is above the groove 109.

[0033] A filter plate 108 is installed to prevent large ice blocks from entering the testing chamber 101 and damaging the product 01 to be tested. In addition, a trough 109 is provided at the bottom of the filter plate 108 so that these large ice blocks can fall into the testing chamber 101 through the trough 109. Furthermore, a finer ice-blocking net 111 is installed on the inner opening of the exhaust chamber 110 to intercept ice chips or small ice blocks and keep them in the testing chamber 101.

[0034] In addition, a drain pipe is connected to the bottom of the testing box 101, and a filter screen is provided at the connection port of the drain pipe. The front of the testing box 101 is provided with a door 102, while the back of the testing box 101 is provided with a slag discharge drawer 113, which is slidably connected to the bottom of the testing box 101.

[0035] Therefore, after the ice shards and ice cubes enter the testing chamber 101, only those that melt into water and flow away, and those that are too small to be carried away by the wind, remain in the testing chamber 101. Finally, after the testing is completed, these ice shards and ice cubes are removed through the slag discharge drawer 113 for reuse, minimizing consumption.

[0036] In summary, this invention provides a testing chamber 101 for simulating extreme high-altitude environments. The testing chamber 101 is completely sealed to prevent external interference. An air inlet pipe 105 and an exhaust pipe 112 are respectively installed on the left and right sides of the testing chamber 101, and these pipes are connected to an external fan and exhaust fan, respectively. This allows for the simulation of high-speed airflow within the testing chamber 101 and the adjustment of the air pressure inside, making the environment within the testing chamber 101 closer to real-world extreme high-altitude environments. A mixing chamber 104 is located between the air inlet pipe 105 and the testing chamber 101. An ice slag funnel 106 is installed on the mixing chamber 104, and a crusher 107 is located at the bottom of the ice slag funnel 106. Therefore, ice slag or small ice cubes can be mixed into the mixing chamber 104, allowing these ice slag to be introduced into the testing chamber 101 along with the high-speed airflow, thereby simulating the environment within high-altitude clouds.

[0037] A filter plate 108 is installed at the inner opening of the mixing chamber 104 to prevent excessively large ice blocks from entering the testing chamber 101 and damaging the product 01 to be tested. Additionally, a trough 109 is provided at the bottom of the filter plate 108 to allow large ice blocks to fall into the testing chamber 101. Furthermore, a finer ice-blocking mesh 111 is installed at the inner opening of the exhaust chamber 110 to trap ice fragments or small ice blocks within the testing chamber 101. Finally, after testing, these ice fragments and blocks are removed through the slag discharge drawer 113 for reuse, minimizing waste.
