Description

Technical Field

[0001] The utility model relates to the technical field of combustion performance detection devices, in particular to a detection device for the combustion performance of litter. Background Art

[0002] In the fields of environmental science, forest ecology, fire science, etc., the combustion performance of litter (the part of plants that die and fall to the ground in the forest) has always been an important research direction. The combustion performance of litter is not only related to the risk assessment and prevention of forest fires, but also directly affects the stability of the forest ecosystem and the carbon cycle process. Therefore, accurately and efficiently detecting the combustion performance of litter is of great significance for protecting forest resources and the ecological environment.

[0003] Traditional detection devices for the combustion performance of litter often have some problems. First of all, they usually cannot simulate the complex terrain conditions where litter is located in the natural environment, such as the influence of slope changes on the combustion process. This limitation makes the detection results deviate greatly from the actual situation and it is difficult to accurately reflect the combustion performance of litter in the real environment. Secondly, the waste gas generated during the combustion process by traditional devices is often directly discharged into the environment, posing potential health and safety risks to experimental personnel and the surrounding environment. In addition, these devices often lack an effective waste gas purification and exhaust system and cannot effectively reduce the harmful gas emissions generated during the combustion process, thus exacerbating the environmental pollution problem. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a detection device for the combustion performance of litter.

[0005] The utility model is realized by adopting the following technical solutions: A detection device for the combustion performance of litter includes a slope adjustment mechanism, a detection main body, and a waste gas treatment mechanism. The slope adjustment mechanism is located inside the detection main body, and the waste gas treatment mechanism is located on the top of the detection main body.

[0006] As a further improvement of the above solution, the slope adjustment mechanism includes a combustion base. The bottom of the combustion base is fixedly connected with a first movable part. The inner wall of the first movable part is rotatably connected with a first connecting column. The outer wall of the first connecting column is fixedly connected with a first fixing part. The bottom of the first fixing part is fixedly connected with a support column. The bottom of the support column is fixedly connected with a heat insulation plate. The inner wall of the heat insulation plate is rotatably connected with a lead screw. The outer wall of the lead screw is fixedly connected with a large gear. The large gear is meshed with a chain. One end of the chain away from the large gear is meshed with a small gear. The inner wall of the small gear is fixedly connected with a motor. The bottom of the motor is fixedly connected with a base. The outer wall of the lead screw is rotatably connected with a sliding column. The inner wall of the sliding column is fixedly connected with a lifting rod. One end of the lifting rod away from the sliding column is fixedly connected with a telescopic rod.

[0007] Through the above technical solution, a lead screw, a large gear, a small gear, a chain, a motor and a sliding column are installed. The motor drives the small gear to rotate, thereby driving the chain and the large gear to rotate. The lead screw rotates under the action of gear transmission. Since the sliding column is threadedly connected to the lead screw, the rotation of the lead screw causes the sliding column to move up and down along the axial direction of the lead screw. Since the lifting rod and the telescopic rod are fixedly connected to the sliding column, the telescopic rod will move together with the sliding column, thereby changing the inclination angle of the combustion base.

[0008] As a further improvement of the above solution, the number of the support columns is set to two, and the number of the telescopic rods is set to two.

[0009] Through the above technical solution, by installing the support column and the telescopic rod, the function of adjusting the slope of the combustion base is realized. Specifically, the support column serves as the main support structure. Through the telescopic movement of the telescopic rod, the included angle between the combustion base and the horizontal plane can be changed, so as to simulate the combustion environment under different slope conditions.

[0010] As a further improvement of the above solution, the detection main body includes a housing. One side of the housing is fixedly connected with a transparent observation housing. Doors are rotatably connected to both ends of the front side of the transparent observation housing. One side of the transparent observation housing is fixedly connected with a movable device, and an observation scale plate is rotatably connected to the inner wall of the movable device.

[0011] Through the above technical solution, by installing the observation scale plate and combining it with the transparent observation housing, it allows experimenters to observe key parameters such as the flame height and spread speed during combustion in real time without opening the detection main body.

[0012] As a further improvement of the above solution, the inner wall of the housing is fixedly connected with a heat insulation plate. The inner wall of the housing is in contact connection with the combustion base. The bottom of the telescopic rod is fixedly connected with the top of the heat insulation plate.

[0013] Through the above technical solution, by installing the heat insulation plate, the heat insulation plate separates the combustion area from other parts of the detection device such as the motor, preventing the high temperature from damaging the internal sensitive components and extending the service life of the device.

[0014] As a further improvement of the above solution, the waste gas treatment mechanism includes a gas collecting hood. The gas collecting hood is flange-connected with a first pipe on the inner wall. A fan is fixedly connected to the inner wall of the first pipe. One end of the first pipe away from the gas collecting hood is flange-connected with a treatment unit, and a second pipe is flange-connected to the outer wall of the treatment unit.

[0015] Through the above technical solution, by installing a fan, the rotation of the fan generates negative pressure, enabling the exhaust gas generated during the combustion process to be captured by the air hood more quickly and effectively and guided into the first pipeline, thereby improving the efficiency of exhaust gas collection.

[0016] As a further improvement of the above solution, the top of the outer shell is fixedly connected to the bottom of the air hood, and the first pipeline and the processing unit are located on the back of the outer shell.

[0017] Through the above technical solution, by installing an air hood and a processing unit, and through the combined use of the air hood and the processing unit, the exhaust gas generated during the combustion process can be quickly collected and processed, thereby shortening the experimental period and improving the experimental efficiency.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] In the present utility model, by setting a slope adjustment mechanism, first, the staff places the litter on the top of the combustion base through the opened door, and the staff ignites the litter through the burner to conduct an experiment in the transparent observation outer shell. When slope adjustment is required, the motor receives a start signal and starts to work. The motor drives the small gear to rotate. The small gear meshes with the large gear through a chain, thereby driving the large gear to rotate. The large gear drives the lead screw to rotate synchronously. The rotation of the lead screw causes the sliding column to move up and down along the axial direction of the lead screw. The sliding column drives the lifting rod to move up and down accordingly, and the lifting rod drives the telescopic rod to move up and down, achieving a change in the inclination angle of the combustion base and realizing slope adjustment.

[0020] In the present utility model, by setting an exhaust gas treatment mechanism, the exhaust gas from combustion passes through the air hood, and then the fan transports the exhaust gas through the first pipeline to the processing unit. The processing unit includes exhaust gas treatment equipment, such as filters, adsorbents, etc., for removing harmful substances in the exhaust gas. The exhaust gas treated by the processing unit is discharged or recycled through the second pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
