Due to seasonal reasons, both summer and winter are seasons with high fire occurrences throughout the year, and we should focus on prevention. Due to the dry weather in winter, all kinds of fire, electricity and gas use greatly increase, leading to a large number of fire accidents. According to statistics from the fire department, the incidence of winter fires in China accounts for 40% of the total number of the year. Therefore, in order to effectively reduce the incidence of fires, we must first do a good job in winter fire prevention and control. For this reason, here are some superficial views on how to do a good job in winter fire prevention and some information about fire fighting robot.
Ⅰ.Several Characteristics of Winter Fire
1.Fires frequently occur in crowded places.
Due to the cold weather in the winter, people like to gather in air-conditioned crowded places such as tea houses and coffee shops to entertain, chat, and play cards to pass the time. In some crowded entertainment venues, a large number of combustible materials are used in violation of regulations to decorate the venues. Once these combustible materials encounter open flames or sparks such as cigarette butts and fireworks thrown away by consumers, they are easily ignited and spread rapidly.
2.Electrical fire accidents have increased.
If you have a chance to see the fire department's alarm record, you can find that electrical fire accidents in winter are significantly higher than other seasons. The 24-hour full-load operation of air conditioners in crowded places can easily lead to electrical fires in such places. Long-term uninterrupted operation of electrical appliances, coupled with their long service life and high socket pressure, can easily lead to electrical fires.
3.Fires are frequent in rural areas.
In recent years, most of the fatal fire accidents occurred in rural areas in winter. This topic is a bit heavy, but we should not avoid it. Because we can only do a better job of fire prevention in rural areas if we face the reality squarely, and can avoid more casualties. Although heating equipment such as electric blankets and electric heaters are cheap and easy to use, they have great safety risks and are likely to cause fire accidents and even deaths due to electric leakage.
Ⅱ.Preventive Measures Against Fire in Winter
1.Strengthen the supervision of fire hazards.
We must fully understand the social hazards of winter fires and attach great importance to winter fire prevention and control. Government departments should implement winter fire prevention and control work to functional departments at all levels, and the functional departments will take the lead to organize the implementation; functional departments should strengthen the inspection of key units and key places according to the annual winter fire prevention work plan, and strive to start from the source to do a good job in fire prevention and control.
2.All sectors of society must conduct self-examination of hidden dangers.
It is necessary to mobilize social units to actively carry out self-inspection of fire hazards and daily fire prevention inspections; organize and mobilize firefighting volunteers to go to various places to find fire hazards. In rural areas, town and village-level joint fire prevention organizations should be mobilized to increase focus on the elderly and families with left-behind children.
3.Intensify propaganda on fire prevention and control in winter.
It is necessary to make full use of mainstream media such as newspapers and TV stations, new media such as Weibo, WeChat public account, and large electronic display screens along the street to strengthen the publicity of winter fire prevention and control work in an all-round way, so that all sectors of society can understand and do To do a good job in winter fire prevention and control, to learn the necessity and importance of common sense of fire safety, and to fully enhance the fire safety awareness and self-rescue ability of all sectors of society.
The crawler robot moves according to the contact between the chain-track sound card rack and the road surface. The development trend of the chain-track sound card rack is large indoor space and more stable driving. The universal chain track robot chassis, the whole vehicle adopts the suspension plan, and it can achieve long-term load shock absorption. The height-to-width ratio adjustment of the automobile chassis cooperates with the driving force motor, so that this model has the advantages of low automobile chassis, strong basis, and strong impact resistance. It is commonly used in intelligent robot movement solutions in chaotic natural environments.
The track main box of the crawler robot touches the road surface, and the driving wheel does not touch the road surface. When the motor drives the driving wheel to rotate, under the drive torque effect of the reducer, the driving wheel is continuously coiled around the chain rail from the rear by the transmission gear on the driving wheel and the toothed transmission gear of the chain rail chain. If the driving force is sufficient and large enough to get rid of the frictional resistance of driving, the roller will flip forward to make the equipment move forward. The front, rear, left, and right chain tracks of the entire chain track organization can be controlled separately, thereby reducing the road turning radius.
Crawled robot platform are commonly used in mechanical equipment and outdoor work equipment.
The strategy of Zhengzhou Defy is to start with robot mobile solutions and mechanical hand, to grow with relentless pursuit of innovative technology and high quality, and finally to make our robots do complicated and dangerous jobs instead of human beings all over the world.
