[0028] Embodiment 1

[0029] This embodiment provides an experimental device for testing the dynamic parameters of litter combustion, as Figure 1As shown, it includes an electronic scale 4 for measuring the weight of withered and fallen leaves. A radiometer 8 is provided on the side of the electronic scale 4, and a thermocouple 9 is provided above the electronic scale 4. The combustion dynamic parameters of withered and fallen leaves are monitored by the electronic scale 4, the radiometer 8, and the thermocouple 9.

[0030] It also includes a circular slide rail 1. The electronic scale 4 is located at the center of the circular slide rail 1, and a camera 7 for aligning with the withered and fallen leaves is provided outside the circular slide rail 1.

[0031] As Figure 1 shown, an adjustable blower 2 is slidably connected to the top of the circular slide rail 1. A slider is fixedly installed at the bottom of the adjustable blower 2. The slider adopts an arc structure. By sliding the slider, the position of the adjustable blower 2 is changed, that is, the blowing direction of the adjustable blower 2 is changed to test the influence of winds at different angles on the combustion of withered and fallen leaves. A wind baffle 3 is slidably connected to the top of the circular slide rail 1. The wind baffle 3 adopts an arc structure. The ambient wind is blocked by the common wind baffle 3 to reduce the error of the combustion experiment.

[0032] As Figure 2 shown, a height adjustment assembly 5 is provided on the top of the electronic scale 4. The height adjustment assembly 5 includes a pressure equalizing plate 51, an adjustment rod 52, and a combustion support plate 53. The top of the pressure equalizing plate 51 is rotatably connected to the adjustment rod 52. The left end of the combustion support plate 53 is rotatably connected to the pressure equalizing plate 51. The end of the adjustment rod 52 contacts the combustion support plate 53. The pressure equalizing plate 51 is fixedly installed on the top of the electronic scale 4. Withered and fallen leaves are placed on the combustion support plate 53. A plurality of grooves are provided at the bottom of the combustion support plate 53. The plurality of grooves are distributed at equal angular intervals in a straight line. The adjustment rod 52 is inserted into the grooves.

[0033] The combustion support plate 53 is supported by rotating the adjustment rod 52. The groove into which the adjustment rod 52 is selected to be inserted is used to adjust the inclination angle of the combustion support plate 53, that is, to change the area of the wind blown by the adjustable blower 2 acting on the withered and fallen leaves. The pressure equalizing plate 51 distributes the gravity of the adjustment rod 52, the combustion support plate 53, and the withered and fallen leaves thereon, making the gravity borne by the electronic scale 4 uniform and reducing the weighing error.

[0034] In this embodiment, by selecting one of the plurality of grooves to be engaged with the adjustment rod 52, the inclination angle of the combustion support plate 53 is adjusted, that is, the area of the wind blown by the adjustable blower 2 acting on the withered and fallen leaves is changed. At the same time, the adjustable blower 2 is slid to change the included angle between it and the withered and fallen leaves to test the influence of winds at different angles on the combustion of withered and fallen leaves.

[0035] Embodiment 2

[0036] Based on Embodiment 1, this embodiment proposes an experimental device for testing the combustion dynamic parameters of litter, as Figure 3 and Figure 4As shown, an avoidance component 6 is provided at the end of the thermocouple 9. There is also an avoidance component 6, which includes a vertical plate 61, a support rod 63, and a layer block 64. The vertical plate 61 is arranged on the left side of the electronic scale 4. A slideway is opened on the side of the vertical plate 61. The end of the thermocouple 9 slides up and down in the slideway. A layer block 64 is opened inside the vertical plate 61. The rod of the thermocouple 9 is hinged to the support rod 63, and the support rod 63 is clamped with the layer block 64.

[0037] A plurality of layer blocks 64 are provided and are arranged at equal intervals in a straight line in the slideway on the side of the vertical plate 61. A scale is fixedly installed on the side of the vertical plate 61. Selecting a layer block 64 to be clamped with the support rod 63 can adjust the height of the thermocouple 9. When adjusting the inclination angle of the combustion support plate 53, by adjusting the height of the thermocouple 9, the distance between the thermocouple 9 and the height adjustment component 5 is maintained. At the same time, the support rod 63 and the layer block 64 cooperate to support the thermocouple 9, preventing the thermocouple 9 from tilting, resulting in a change in the distance between its end and the height adjustment component 5, which affects the monitored combustion dynamic data.

[0038] There is a distance between the end of the support rod 63 and the vertical plate 61. A positioning member 62 is slidably connected at the distance between the vertical plate 61 and the support rod 63. The positioning member 62 adopts a comb-shaped structure. When the positioning member 62 is inserted into the vertical plate 61, the positioning member 62 is located at the end of the support rod 63.

[0039] The support rod 63 is limited by the positioning member 62. When the height of the thermocouple 9 needs to be adjusted, the positioning member 62 is pulled away from the end of the support rod 63, and the support rod 63 can rotate upward. At this time, the thermocouple 9 is pulled upward to increase the distance between the support rod 63 and the layer block 64, and the support rod 63 can be taken out of the vertical plate 61.

[0040] In this embodiment, when adjusting the inclination angle of the combustion support plate 53, by adjusting the height of the thermocouple 9, the distance between the thermocouple 9 and the height adjustment component 5 is maintained. At the same time, the support rod 63 and the layer block 64 cooperate to support and fix the position of the thermocouple 9, preventing the thermocouple 9 from tilting, resulting in a change in the distance between its end and the height adjustment component 5, which affects the monitored combustion dynamic data.

[0041] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
