Description

Technical Field

[0001] The present invention belongs to the technical field of heat transfer detection of composite materials. Specifically, it particularly relates to a rapid test device for the heat transfer performance of materials. Background Art

[0002] A rapid test device for the heat transfer performance of fiber composite materials refers to a device that can quickly and accurately measure the heat transfer performance of fiber composite materials under different conditions. This device precisely measures and analyzes key parameters such as the heat transfer rate and thermal conductivity of fiber composite materials by simulating the actual working environment and application conditions; the rapid test device for the heat transfer performance of fiber composite materials is of great significance for promoting the development and application of fiber composite material technology. By quickly and accurately testing the heat transfer performance of fiber composite materials, it can provide strong data support for scientific researchers and enterprises, helping them better understand the performance characteristics and application scope of the materials, thereby promoting scientific and technological innovation and industrial upgrading.

[0003] In the operation process of the existing rapid test devices for the heat transfer performance of fiber composite materials, a closed detection box is generally used to heat and detect the samples. Although this design ensures the stability and accuracy of the test environment, it brings some inconveniences and potential safety hazards in the actual operation process; specifically, when the test is completed, the staff needs to manually take out the samples from the detection box. However, since the detection box will reach a relatively high temperature during the test and there will still be some residual hot air in the box after the test is completed, when the staff reaches into the detection box to take the samples, it is not only inconvenient to operate but also faces the risk of being scalded by the hot air. This risk not only affects the work efficiency but also may pose a threat to the personal safety of the staff. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the invention with reference to the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts shall fall within the scope of protection of the invention.

[0021] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0022] Please refer to Figures 1-8 As shown, the present invention is a rapid test device for the heat transfer performance of materials, including a detection box 1. A connecting shaft 2 is rotatably installed inside the detection box 1. One end of a rod member 3 is rotatably installed on the connecting shaft 2, and the other end of the rod member 3 is rotatably installed with a slider 4. The slider 4 is slidably connected inside a chute 26. The chute 26 is opened on a box door 5. The box door 5 is rotatably installed on the detection box 1. A detection frame 6 is fixedly installed on the connecting shaft 2. An electric heater 7 is fixedly installed inside the detection frame 6. Two fixing mechanisms are arranged inside the detection frame 6, and the fixing mechanisms are used for clamping composite materials.

[0023] The working principle of the rapid test device for the heat transfer performance of materials proposed by the present invention is as follows: First, open the box door 5. During the opening process of the box door 5, the slider 4 is synchronously driven to slide along the inside of the chute 26 opened on the box door 5, thereby driving the rod member 3 to rotate inside the detection box 1, and then driving the connecting shaft 2 to rotate, and further driving the detection frame 6 to rotate, so that the detection frame 6 rotates to the outside of the detection box 1. At this time, the fiber composite material sample can be clamped by the fixing mechanism, avoiding the need for the operator to reach into the detection box 1 for fixing.

[0024] Similarly, after the fiber composite material sample is fixed, close the box door 5, thereby driving the above device to reset.

[0025] It should be noted that after the heat transfer performance test of the fiber composite material sample is completed, open the box door 5, thereby driving the detection frame 6 to the outside of the detection box 1, which is convenient for the staff to take it, avoiding the hands reaching into the detection box 1 and being scalded by the remaining hot air, and improving the safety.

[0026] In one embodiment, for the above clamping mechanism, the clamping mechanism includes a frame 8 provided on the detection frame 6. The frame 8 is fixedly installed inside the detection frame 6. A turbine 9 is rotatably installed inside the detection frame 6. The turbine 9 is fixedly installed with a clamping hand 10. A rotating shaft 11 is rotatably installed inside the frame 8. One end of a connecting rod 12 is fixedly installed on the rotating shaft 11, and the other end of the connecting rod 12 is rotatably installed on the clamping hand 10.

[0027] In one embodiment, for the above turbine 9, there are two turbines 9, clamping hands 10, rotating shafts 11 and connecting rods 12. The two turbines 9 are engaged with a worm 13, and the worm 13 passes through the frame 8 and is rotatably installed on the detection frame 6.

[0028] The working principle of a rapid test device for the heat transfer performance of materials proposed by the present invention is that by rotating the worm 13, the two turbines 9 are driven to rotate, and then the clamping hands 10 are driven to rotate, thereby driving the two connecting rods 12 and the rotating shaft 11 to rotate. Furthermore, the two clamping hands 10 move simultaneously towards the central axis of the frame 8, so as to fixedly clamp the fiber composite material sample, and then it is convenient to carry out subsequent heat transfer performance detection.

[0029] In one embodiment, for the above detection box 1, a water storage tank 14 is fixedly installed inside the detection box 1. A filter screen 15 is movably installed in the water storage tank 14. One end of a water delivery pipe 16 is fixedly communicated with the water storage tank 14, and the other end of the water delivery pipe 16 passes through the detection box 1 and is communicated with a pump body 17.

[0030] In one embodiment, for the above pump body 17, the pump body 17 is fixedly installed on a water tank 18. The water tank 18 is fixedly installed on the top of the detection box 1, and a water pump is arranged inside the water tank 18.

[0031] In one embodiment, for the above water tank 18, the water tank 18 is communicated with a flow dividing plate 19 through a water pipe. The flow dividing plate 19 is fixedly installed on the inner top surface of the detection box 1, and the flow dividing plate 19 is fixedly installed with a plurality of spray holes 20.

[0032] In one embodiment, for the above detection frame 6, a hole 21 is opened at the bottom of the detection frame 6, and the detection frame 6, the flow dividing plate 19 and the water storage tank 14 are flush with each other.

[0033] The working principle of a rapid test device for the heat transfer performance of materials proposed by the present invention is that after the heat transfer performance detection of the fiber composite material sample is completed, the water pump inside the water tank 18 is started, so that the water is conveyed through the water pipe to the inside of the flow dividing plate 19 and finally sprayed out through the spray holes 20, thereby cooling the fiber composite material sample and the inside of the detection box 1, preventing high temperature from possibly damaging the components inside the detection box 1 and shortening its service life.

[0034] It should be noted that after cooling down, it is also possible to avoid the situation of scalding when subsequent staff take out the fiber composite material sample.

[0035] Furthermore, during the above operation, the water that has not been evaporated by high temperature drips through the holes 21 onto the filter net 15 to filter impurities, and then drips into the inside of the water storage tank 14 for storage. Finally, the pump body 17 is started to suck the filtered water into the inside of the water tank 18 through the water delivery pipe 16 for secondary utilization.

[0036] In one embodiment, for the above-mentioned box door 5, a transparent observation window 22 is fixedly installed on the box door 5, a handle 23 is fixedly installed on the box door 5, and a sliding groove 26 is opened on the side away from the handle 23.

[0037] In one embodiment, for the above-mentioned detection box 1, a control panel 24 is fixedly installed on one side of the detection box 1. The control panel 24 is used to display the temperature inside the detection box 1. The control panel 24 is electrically connected to a control button 25, and the control button 25 is used to adjust the temperature of the electric heater 7.

[0038] The working principle of a rapid test device for the heat transfer performance of materials proposed by the present invention is that the detection process of the fiber composite material sample can be observed in real time through the transparent observation window 22, and the temperature inside the detection box 1 is displayed through the control panel 24. At the same time, the temperature of the electric heater 7 is adjusted by using the control button 25, so as to test the fiber composite material sample.
