Description

An agricultural deep well rescue device

technical field

The invention belongs to the technical field of rescue and salvage equipment, and in particular relates to an agricultural deep well rescue device suitable for salvaging people or objects in small-diameter deep wells in rural areas.

Background technique

Agricultural wells are an important facility for farmland irrigation and drinking water for humans and animals in my country, especially in the north, and an important material basis for the development of agricultural production. Agricultural mechanized wells are drilled into vertical deep wells, generally ranging from tens of meters to tens of meters, with a diameter of 30 to 50 centimeters. Many mechanized wells are distributed in the fields due to long-term lack of management, where farmers, children or animals, etc. If you don’t pay attention, you will fall into the well and cause safety accidents. In recent years, incidents of cannibalism and wounding have occurred frequently in rural irrigation wells, causing many families to suffer misfortune, seriously threatening the safety of farmers’ lives and property, and affecting rural economic development. According to incomplete statistics, there are approximately 4 to 5 million motorized wells in the country, and 400 to 500 incidents of cannibalism and wounding by motorized wells occur every year in the country, resulting in direct economic losses of 36 million yuan.

Generally there are three kinds of rescue methods in the field of deep well rescue at present: 1. Rescuers directly go down the well to rescue 2. Rescuers utilize self-made ropes to rescue 3. Large-scale excavating equipment rescues. All there is very big defect in these three kinds of methods themselves. 1. The rescue method that the rescuers directly go down the well is very dangerous to the rescuers themselves, and the firefighters who go down the well to rescue often go down the well in an upside-down state. If a person stands on his head for a long time, dizziness, dyspnea, etc. will appear, and even fainting will occur in severe cases. When the well is narrow and the person falling into the well falls into a deep position, it will become more dangerous for the rescuers to go down the well to rescue people, because even the rescuers themselves are easy to get stuck by the well wall. In many cases, this method cannot be implemented. 2 The scope of use of self-made rope rescue is very small, and it can only play its role when the person who fell into the well is conscious and can move some limbs. It will fail when it is clear or the limbs are stuck and unable to move. 3 The time required for this rescue method of using large-scale excavation equipment is particularly long, often reaching more than 5 hours, which greatly reduces the survival rate of those who fell into the well. In the process of excavator digging, if it is not handled properly, it will easily cause landslides and cause huge potential safety hazards.

According to the statistical data, in recent years, there have been frequent accidents in which people accidentally fell into the well. Although fire rescue personnel were able to rush to the scene to carry out rescue when many accidents occurred, there are not many examples of successful rescue. Maintaining above 70% is shocking.

Therefore, it is very necessary to design an efficient and safe underground rescue machine to solve many problems in the field of underground rescue in my country, and to ensure the safety of those who fall into the well.
