[0020] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 and 2 As shown in the figure, this embodiment discloses an experimental device for burning fallen leaves with different moisture contents, including a combustion chamber 1 and a control and observation chamber 2, with a glass partition 3 between the combustion chamber 1 and the control and observation chamber 2.

[0022] The control observation room 2 is equipped with a drying box. The drying box is used to measure the moisture content of fallen leaves. The basic principle of measuring the moisture content in the drying box is to calculate the moisture content by measuring the weight change of the material before and after drying.

[0023] The combustion chamber 1 is equipped with sensor components, a video camera, an air conditioner 4, a humidifier 5, a fireproof cover 6, and a remote-controlled trolley 7. A lifting device 8 is installed above the fireproof cover 6, and a collector 9 for collecting fallen leaves is installed below the fireproof cover 6. The collector 9 is connected to the fireproof cover 6 by multiple steel wire ropes 10. The lifting device 8 can lift the fireproof cover 6 and the collector 9 together.

[0024] A water tank 11 is provided below the collector 9. The area of ​​the water tank 11 is larger than the area of ​​the collector 9, so that after the lifting device 8 lowers the collector 9, the collector 9 can be placed in the water tank 11.

[0025] The sensor components mainly include temperature and humidity sensors and infrared temperature sensors. The sensor components and video camera are installed and fixed on the inner wall of combustion chamber 1. The sensor components and video camera are connected to the controller of control observation room 2 via data cable. The controller can be a desktop computer, and the desktop computer host is equipped with a corresponding data interface.

[0026] The remote-controlled vehicle 7 is equipped with a robotic arm 701, and a burner 702 is located at the front end of the robotic arm 701. The burner 702 is connected to a gas cylinder via a hose. The burner 702 has a built-in igniter to ignite the combustion gas. It should be noted that both the remote-controlled vehicle 7 and the robotic arm 701 are existing technologies. Those skilled in the art can purchase existing modules online for assembly, or directly purchase existing finished products.

[0027] In this embodiment, the collector 9 is a wire basket made of metal. The wire basket is arranged horizontally in this embodiment.

[0028] In this embodiment, the combustion chamber 1 and the control observation room 2 are converted from shipping containers, and the outer walls of the shipping containers corresponding to the combustion chamber 1 and the control observation room 2 are provided with doors 13.

[0029] In this embodiment, the lifting device 8 is a winch, which is fixed to the roof of the combustion chamber 1, and the rope wound on the winch is connected to the fireproof cover 6.

[0030] like Figure 3 As shown, the fireproof cover 6 includes a shell 601, the bottom surface of which is covered with a fireproof layer 602, and a lifting lug 603 is provided on the top of the shell 601. The lifting lug 603 is connected to the rope on the winch. The wire rope 10 is connected to the shell 601.

[0031] The operating principle of this invention is as follows: fallen leaves in the sampling area are collected, a portion of the collected fallen leaves are selected for a burning experiment on the moisture content of the fallen leaves, and then the remaining part is subjected to a burning experiment.

[0032] A layer of fallen leaves is laid flat in the collector 9. The lifting device 8 is used to lift the fireproof cover 6 and the collector 9 together. Then, the burner 702, which has a built-in igniter, can ignite the combustion gases to form a fire source. The position and direction of the fire source can be adjusted by operating the remote control trolley 7 and the robotic arm 701, thereby simulating the effect of external fire heat radiation on the fallen leaves.

[0033] The air conditioner remote control can be used to adjust the air temperature and air volume of the air conditioner 4. The humidifier 5 can be used to adjust the air humidity in the combustion chamber 1. The video camera and sensor components can monitor and record the combustion status, environmental conditions and combustion temperature in the combustion chamber 1 in real time, so as to better understand the combustion process of the debris.

[0034] The ash from the burning leaves in the collector 9 can fall into the water tank 11 below. After the leaves in the collector 9 have burned out, the lifting device 8 lowers the fireproof cover 6 and the collector 9 together. At this time, the collector 9 can be placed in the water tank 11, and the water in the water tank 11 extinguishes the burning ash and charcoal. At the same time, the bottom of the fireproof cover 6 contacts the ground of the combustion chamber 1, forming a certain degree of isolation, which is conducive to the extinguishing of the burning ash.

[0035] In this embodiment, a sealing strip 12 is provided at the bottom of the fireproof cover 6. The sealing strip 12 is made of high-temperature resistant material and can improve the sealing performance between the bottom of the fireproof cover 6 and the ground of the combustion chamber 1. The sealing strip 12 is fixed to the bottom edge of the cover 601.

[0036] It should be noted that an exhaust fan and an air inlet are installed on the outer wall of the container corresponding to combustion chamber 1.

[0037] Example 2

[0038] like Figure 4 As shown, in this embodiment, the basket is arranged at an angle, and the slope of the basket can be controlled by adjusting the length of each steel wire rope 10 to simulate the burning of fallen leaves at different slopes. The rest of the structure in this embodiment is the same as in Embodiment 1.

[0039] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
