Embodiment 1

[0026] Embodiment 1: In this embodiment, the firefighter's rescue device is used as a test sample. During the experiment, the fireman's rescue device of the tested sample is placed on the sample support 9 in the disaster element receiving device 8, and the first hydraulic support 16 is adjusted so that the slideway 12. The bottom end is 2 m away from the surface of the sample support 9. Adjust the surface of the sample support 9 so that the surface of the test sample is perpendicular to the linear direction of the slideway 12. Add the mixture of rock and soil to the supply tank 14. Adjust the second hydraulic support 18 to make the slideway 12. The inclination angle is 60°. Adjust the first hydraulic support 16 so that the inclination angle of the supply tank 14 is 30°. Five displacement sensors 11 are arranged on the surface of the slideway 12. The distance between two adjacent displacement sensors 11 is 0.6 m. Take Go to the first baffle plate 13 on the side of the supply tan...

Embodiment 2

[0027] Embodiment 2: In this embodiment, the emergency communication equipment is used as a test sample, soil is added to the supply tank 14, the support 18 is adjusted to make the slideway inclination angle 45°, and the hydraulic support 16 is adjusted to make the supply tank 14 inclination angle 45°. Adjust the combined hydraulic support 16 so that the bottom of the slideway 12 is 2 m away from the upper surface of the sample support 9, put down the first baffle 13 on the side of the supply tank 14, and adjust the hydraulic push rod 15 so that the second baffle 19 on the side of the supply tank 14 pushes the soil Sliding, the soil falls on the disaster element receiving device 8 through the slideway 12 to simulate the landslide disaster process. The signal received by the sensor is input to the main control computer 1 through digital-to-analog conversion for data storage and calculation processing, and the data acquisition is closed after 2 hours of the experiment. device.

Embodiment 3

[0028] Embodiment 3: as image 3As shown, in this embodiment, the test samples in the disaster element receiving device 8 are reasonably arranged to study the damage degree of the samples in different positions. The sample holder 9 is set in the disaster element receiving device 8, with 5 rows and 6 columns in total, each The interval between each column is 0.6 m, and the interval between each column is 0.5 m. Helmet lights are selected as experimental samples, and the helmet lights are placed horizontally on the upper surface of the sample support 9 in rows 1, 3, and 5, and the helmet lights are vertically placed in rows 2 and 4. Place on the upper surface of the sample holder 9, wherein the lamp face of the helmet lamp of the second exercise is upward, and the bottom surface of the helmet lamp of the fourth exercise is upward, add rocks into the supply tank 14, adjust the bracket 18 to make the inclination angle of the slideway 12 Adjust the first hydraulic support 16 so tha...

Abstract

The invention discloses a device for simulating and testing a damage mechanism of emergency resources under the action of geological disasters, and belongs to the field of safety engineering detection. The device comprises an experimental platform, a geological disaster simulation system, an artificial climate simulation system, a disaster-bearing system and a measurement and control system; the geological disaster simulation system and the disaster-bearing system are arranged on the experimental platform; and the center line of the artificial climate simulation system coincides with the center line of a slide way in the geological disaster simulation system and is located on the upper portion of the slide way, the geological disaster simulation system is connected with the disaster-bearing system, and the disaster-bearing system is connected with the measurement and control system. The defect that the emergency resource performance detection is incomplete under the conditions of lack of actual disaster conditions and multi-disaster coupling in the prior art is overcome, support is provided for perfecting the emergency resource performance detection method, and a basic experimental device is provided for researching the damage mechanism of the emergency resources under the actual disaster conditions and the multi-disaster coupling conditions.

Description

technical field [0001] The invention relates to the field of safety engineering detection, in particular to a damage simulation experiment system for small emergency equipment under the action of multiple disasters. Background technique [0002] Emergency resources are emergency materials, equipment, facilities, etc. that provide services for rescue and rescue in the event of natural disasters, major or emergency events. When geological disasters such as landslides, mudslides, and landslides occur, emergency resources will be greatly impacted or buried. It is very important to ensure the normal use of emergency resources in the geological disaster environment to ensure the health and safety of emergency rescue personnel and improve the efficiency of emergency rescue. [0003] According to the national standard "Environmental Testing of Electrical and Electronic Products" (GB / T2423.5, GB / T2423.6), when performing impact and collision tests, the samples are fixed on the test ...
